Description

Technical Field

[0001] This utility model relates to the field of PCBA processing and spot welding technology, specifically a positioning structure for PCBA processing and spot welding equipment. Background Technology

[0002] PCBA boards, or PCAs, are generally classified by the insulating part of the substrate. Common materials include bakelite boards, fiberglass boards, and various types of plastic boards. The main processing steps of PCBA boards are to integrate components on the PCB board through SMT and DIP. The main difference is that SMT does not require drilling holes on the PCB, while DIP requires inserting the pins of the components into pre-drilled holes.

[0003] Currently, many PCBA boards are irregularly shaped, and the commonly used positioning structures cannot be adjusted locally, making it difficult to effectively fix irregularly shaped PCBA boards. This leads to unstable fixation during PCBA board processing and spot welding, affecting the spot welding effect. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning structure for PCBA processing spot welding equipment. By using this structure, the problem of existing PCBA processing spot welding equipment positioning structures being unable to make local adjustments and having difficulty in effectively fixing irregularly shaped PCBA boards is solved, resulting in unstable fixing during PCBA board processing spot welding and affecting the spot welding effect.

A connecting block is provided at the end of the hydraulic telescopic rod away from the hydraulic cylinder. A push plate is provided below the connecting block. A moving block is provided at the end of the push plate away from the hydraulic cylinder. The moving block is in contact with the inner wall above the spot welding station. The moving block is moved by pushing the push plate through the hydraulic telescopic rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model proposes a positioning structure for a PCBA processing spot welding equipment. A hydraulic cylinder in positioning component one controls a hydraulic telescopic rod, which pushes a push plate to move a moving block towards the center of the mounting groove.
