Description

Technical Field

[0001] The utility model relates to the technical field of PCBA repair, in particular to a clamping device used for PCBA clamping and repair. Background Art

[0002] In the electronics manufacturing industry, PCBA (Printed Circuit Board Assembly) repair and maintenance are crucial as core components of electronic devices. However, significant issues exist in the current PCBA clamping and repair process. These issues not only increase operating costs for companies but also affect the efficiency and quality of repair work.

[0003] First, mainstream PCBA clamping and repair equipment on the market often uses dedicated fixtures designed for specific products. While this "one-to-one" design approach ensures clamping stability and precision to a certain extent, it also leads to high fixture manufacturing costs. With the increasing variety of products, companies need to design and manufacture new clamps for each new product, which undoubtedly increases their financial burden. Furthermore, the large number of fixture types increases management difficulties, easily leading to improper use of fixtures on the production site, which in turn causes trouble and losses.

[0004] Secondly, most existing PCBA clamping fixtures use a clamping block to press against the edge of the PCBA. While simple and straightforward, this method has significant drawbacks. During the clamping process, the clamping block can easily contact components along the edge of the PCBA, especially small and fragile ones, causing damage. This not only increases repair costs but can also affect the performance and quality of the entire electronic product.

[0005] Furthermore, most existing clamping devices lack height adjustment. Maintenance technicians often need to adjust the height of the PCBA to achieve a more comfortable working posture or a clearer field of view, depending on their height, work habits, or specific repair task requirements. However, traditional clamping devices often fail to meet this requirement, causing fatigue or discomfort during extended work, which in turn affects maintenance efficiency and quality.
