Description

An automatic welding system for flexible circuit boards

technical field

The utility model relates to the field of automatic welding facilities, in particular to an automatic welding system for a flexible circuit board.

Background technique

The flexible circuit board is referred to as the soft board and also called the flexible circuit board. It is a circuit board mainly composed of copper foil, acrylic, epoxy resin thermosetting adhesive and film, etc. Many advantages. Flexible circuit boards are usually used in commercial electronic equipment, car dashboards, printers, hard disk drives, floppy disk drives, fax machines, car mobile phones, general phones, notebook computers, cameras, video cameras, CD-ROM, Hard drives, watches, computers, cameras, medical equipment and other electronic products and equipment. In the production process of flexible circuit boards, it is usually necessary to solder together multiple components. However, in the prior art, there are defects such as slow clamping speed and low welding productivity. In addition, the prior art also has defects such as easy deformation of the flexible circuit board, difficulty in positioning, and low clamping efficiency.

When processing small electronic components such as flexible circuit boards in factories, due to the small size of the components, they are usually placed on structures such as pallets, and then the pallets are stacked on the shelves, or the pallets are clamped by clamps. on the workbench. In the process of processing the components, in the prior art, the pallets are manually transported between the material rack and the worktable, which has low efficiency and a large workload of the operator. Although some automatic handling robots used in engineering can also automatically transport pallets between material racks and worktables by installing specially designed fixtures, it is found in practice that robots position pallets, grab pallets, move pallets, and release pallets. It takes a lot of time to wait, resulting in low efficiency of loading and unloading. In addition, the repeated movement of the robot between empty pallet racks, workbenches, and pallet recovery racks requires high-frequency word positioning and steering, which also takes time, further reducing the efficiency of loading and unloading.

In the factory, the suction cup is a common automatic operation tool, which is used to replace the manual clamping and moving the workpiece by suction. The suction cups in the prior art include a deformable disk body and a suction hole located in the center of the disk body. When using the prior art suction cups to operate precision devices, especially small precision electronic devices, there are many defects. For example, the suction force is too large, the positioning is difficult, and the accurate adsorption is difficult. For example, the suction cup has a single function. For example, a single electronic device is adsorbed at a time, resulting in very low efficiency. In addition, in the prior art, when the workpiece needs to be assembled, combined and other linkage operations, the suction cup is usually installed on the mobile platform to facilitate picking and placing materials. For various operations, multiple devices need to be set up, which leads to high equipment costs and large space occupation.
