Assembly line is also called assembly line. An industrial production method means that each production unit only focuses on the processing of a certain fragment to improve work efficiency and output; according to the assembly line, it can be roughly divided into: belt flow assembly line and board. Chain, double speed chain, plug-in line, mesh belt line, suspension line and drum line these seven types of lines. It generally consists of traction elements, load bearing members, drive devices, tensioners, redirection devices, and support elements. The pipeline has high expandability and can be designed according to the needs of the delivery volume, conveying speed, assembly station, auxiliary components (including quick connectors, fans, lights, sockets, crafts, kanban, console, 24V power supply, wind batch, etc. Welcome; The assembly line is an effective combination of man and machine, which fully reflects the flexibility of the equipment, and it combines the organic combination of the delivery system, accompanying fixtures, on-line special machines, and testing equipment to meet the transportation requirements of various product types. With synchronous transmission (forced) or non-synchronous transmission (flexible), according to the choice of configuration, assembly and transport requirements can be achieved.The transport line is indispensable in the mass production of enterprises.
The advantages of the assembly line
1. Integrate production process, can arrange a variety of workstations on the assembly line to meet production needs;
2. High scalability, can design the assembly line that meets the product production demand according to the factory's demand;
3. Saving factory production costs, to a certain extent, saving the number of production workers, to achieve a certain degree of automated production, the initial investment is not large, the high rate of return
The characteristics of the assembly line
1. The degree of professionalism in the workplace is high.
2. The process is closed, the work place is arranged in the order of the process, and the labor object makes a one-way movement between processes.
3. The processing time for each process is the same as the number of work sites for each process.
4. Each process is produced according to a uniform beat. The so-called beat refers to the production interval of two adjacent products.
Pipeline form
1. According to whether the production object is moving, it can be divided into fixed flow production line and mobile flow production line.
2. According to the number of production varieties, it can be divided into single-type flow production line and multi-type flow production line.
3. According to the degree of continuous production, it can be divided into continuous flow production line and intermittent flow production line.
4. According to the method of realizing rhythm, it can be divided into forced beat water production line and free beat water production line.
5. According to the degree of mechanization, it can be divided into three types of manual, mechanized and automated production lines.
Line features
Plug-in pipeline:
Widely used in the electronics industry. The assembly and configuration of the production line plug-in line can be arbitrarily changed. The speed of the plug-in line can be used to adjust the required conveying speed with the variable-speed knob. The width can be at any time with the width of the circuit board. The fuselage is made of aluminum alloy. The hand-push plug line adopts the aluminum profile rail as the transmission medium. Therefore, the thread body friction is small, no noise, no need to add any lubricating oil, no pollution to the printed board.
Roller assembly line
Features: Wide range of products to be carried, with less restrictions; with the use of stoppers, it can realize the continuous, taktaging and accumulating functions of the product; the lifting and translation device can realize offline repair or detection of products without affecting The entire assembly line runs.
Belt type assembly line
Features: Lighter load bearing, less shape restriction; synchronous operation with the production line, it can realize the product's climbing and steering; with the belt as the carrier and conveying, the product can be smoothly conveyed with low noise; the light material or product can be realized longer Distance delivery.
Double speed chain conveying line
Features: The differential conveying line adopts double-speed chain traction. The tooling plate can be freely conveyed. The blocker is used to position the workpiece to move freely or stop. The workpiece can be automatically lifted at both ends, and the transition can be shifted laterally. It is also possible to install rotation (90 degrees, 180 degrees), special planes, inspection equipment, robots, etc. on the body or on the side of the body.
Packaging line
Technical Note: Packaging production line with a lamp with fan packaging production line and lamp packaging production line, general with fan with fan packaging production line is widely used, simple operation. Mainly used in electronics factory, hardware factory, toy factory and some other packaging workshop. Sitting in the middle of the workbench with a conveyor belt. Improve production efficiency, greatly reduce labor, pay
Uses and features: The packaging production line is composed of cover-type adsorption corrugating machine, paper holder, glue applicator, double-sided machine, paper cutter, preheat roll, double bridge, and glue making machine. Its characteristics are high degree of automation, convenient operation and maintenance, high production efficiency, good quality cardboard, compact structure, beautiful appearance.
Basic knowledge
1: The assembly line must always be from left to right or from right to left?
In general, because most people are accustomed to the right hand, the assembly line flows from left to right. However, because of the limitation of the area of ​​some factories, it may cause at least one of the two or more pipelines to flow in the opposite direction.
2:U-shaped assembly line is the most appropriate?
Not necessarily, the production line layout must be based on the product's characteristics and craftsmanship.
3: The faster the assembly line, the higher its production capacity?
The level of production capacity should depend on the operating time of the bottleneck process and the fastest working time of each station. If it is forced to increase the speed of the production line, it will cause many problems.
4: Is the assembly line designed to ship products?
not completely. The ultimate goal is still to achieve the "continual value flow" of the product.
5: Why is the production rate just lower at the time of work or shift?
It is a stage of preparation and it is a period of time when problems occur. So the management of the shift is very critical. 6: Should the streamline speed settings be kept constant? Every day?
In the same product category should be constant, in the production of different products on the same line, there will be changes in speed. At the same time, because of the problem of new employees, the line speed will decrease.
7: Pitch mark Can only put one product per cell?
Not necessarily, should be the pursuit of stable production flow
8: The faster the pre-assembly process, the better? Is it better to buffer more inventory?
No, it should be produced on demand. However, the pre-assembly processing speed can be slightly faster than the assembly speed.
9: The assembly line is easy to find backlog, Kanban can show progress, and the line length reminds employees to do it quickly?
The first two are correct, but the third is not necessarily. It is not appropriate to urge employees when the production cycle is normal. This can cause unnecessary problems (for example, urges employees to change their hands-on changes, and the inspection is ignored. )
10: The line lengther said that someone asked for leave, couldn't line up? If I can't borrow people, can I separate my employees?
First of all, the assembly line cannot strictly complete the follow-up of all assignments. Because there are few people in one area, there will be a decline in production, but not much. Where else does the emergency response occur? Managers do not consider these common problems, then he can open a factory?
11: Is it reasonable for employees to stand in production or sit in production?
Due to product/condition/facilities
12: The container on the streamline should be dedicated or generic. What is his size?
Most general-purpose designs should be designed, and general-purpose special treatment cannot be used.
13: How highly reasonable is the width of the streamline and the height and width of the machine?
According to ergonomic principles, the sitting table is 65~75CM high, the seat is 38~45, the standing table is 85~95CM, the seat is 58~62, and there are 20~30 board feet.
