In the manufacturing workshop, loading and unloading, as a high-frequency scene in the industry, undertakes the task of connecting workpieces in different processes. However, the traditional loading and unloading method using manual displacement has major defects such as low accuracy and insufficient efficiency.
Manufacturers in various industries have begun to automate transformations, and flexible robots are suitable for multiple scenarios, giving full play to their flexibility and freedom in a small space. Realize batch loading and unloading, accurate position, taking into account the revolutionary changes of efficiency and safety, and double the productivity of the factory.
01 Hot plate welding loading and unloading
Hot plate welding: refers to heating two mutually welded parts to achieve the melting state of the welding surfaces of the materials, and applying a certain pressure to achieve the effect of mutual welding.
Hot plate welding is one of the commonly used welding methods in sanitary ware production workshops. Manual loading and unloading is not only costly in labor (one person can only take care of one piece), but also the hidden dangers caused by high temperature environment to workers are also the focus of concern for manufacturers. .
After a bathroom manufacturer adopts a corporate collaborative robot: one robot can take care of two pieces of equipment, avoiding the risk of high temperature environments, and the easy-to-teach point will shorten the debugging time of products that need to be replaced, and is more suitable for production lines with many varieties and low batches.
02 Computer board/air conditioning board/PCB board loading and unloading
The vigorous development of electronics and electrical appliances has led to the application of printed circuit boards such as PCB boards, computer boards and air-conditioning boards. How to quickly and efficiently integrate various sheet metal components into various electronic devices is a test for the robotic arm.
Take the PCB board as an example. It looks like a thin piece, but it is actually made of multi-layer materials through complicated processes. PCB production has a standardized and strict process flow. We can roughly divide the equipment involved in production into three categories: process equipment, wiring equipment and testing equipment. Copper-clad laminates, synthetic resins and other raw materials and semi-finished products are produced on-site, and are transferred between cutting, drilling, electroplating, etching, coating and other process equipment according to the process.
In the overall PCB process, the use of multi-joint industrial robots to place boards in the exposure, development, browning, etching, and AOI processes is the most popular. Most of the automation connection equipment integrates multi-joint industrial robots. The needs of industry users and system integrators mainly focus on the following aspects:
high tempo, high speed
At present, there are about 1,500 PCB companies in mainland China, mainly distributed in the Pearl River Delta, Yangtze River Delta, and Bohai Rim, where the electronics industry is highly concentrated in developed coastal areas, where industry competition is fierce. How to improve the production efficiency of each link and boost the production capacity of the whole line is an unavoidable link. According to the current technical conditions, the five factors that affect the beat and speed are the size of the board, the movement space of the robot, the change of the suction cup, the stability of the equipment rack, and the number of stations.
High protection, no chips, no oil leakage
In addition to production efficiency, the yield rate is also the focus of PCB manufacturers. Due to the mechanical structure of industrial robots, there will be friction between the moving parts during the movement, which may cause lubricating oil and debris to fall off, which will undoubtedly damage the quality of the PCB and cause user losses.
cost-effective
Industrial robots are the key "components" of connected equipment. Maintaining cost advantages and low failure rates under the condition of meeting the load and tact will further optimize the user's project investment and daily maintenance costs, and achieve the purpose of reducing costs and increasing efficiency.
high usability
From the perspective of effectively utilizing materials and reducing overall costs, PCBs are developing in the direction of large sizes. At present, the size of large-area PCBs is 1250mm*730mm. In order to be able to grasp and carry stably, usually system integrators will design a large number of vacuum chucks, solenoid valves and sensors on the "handle", and the number of sensors has also increased accordingly. In robot design, it is necessary to consider the convenience of installing new external signals; in terms of scheme design and debugging, industrial robots that support offline simulation technology can easily carry out scheme debugging and design optimization in a virtual environment.
High-precision, safer, and easy-to-assemble robots can be easily applied to precision loading and unloading work. Human-machine collaboration and multi-machine collaboration are carried out through robots and automated production equipment to complete multi-station, multi-link, and multi-variety links and switches. Production efficiency and yield rate have been greatly improved.
The six-degree-of-freedom joint design allows the robot to better plan and complete complex motion paths, and can be used freely in a small space.
03 CNC loading and unloading
In mechanical processing, in order to improve work efficiency and product quality, CNC machine tools are more and more used in various parts processing fields, while the traditional manual and cylinder loading and unloading methods have large errors, high defect rates and difficult speed control And other problems, limiting the production efficiency.
In response to the needs of CNC machine tool automation, CNC automatic loading and unloading solutions have been applied.
Using collaborative robots instead of operators, one manipulator can correspond to multiple CNCs, automatically complete the loading and unloading tasks in the process of machine tool processing, effectively improve production efficiency, and easily realize automatic loading and unloading and workpiece clamping for you, which is "machine replacement". mature and ideal products.
At the same time, compared with manual loading and unloading, robot loading and unloading fully guarantees operation consistency and realizes standardized production of products.
