[0002] In the fierce competition of the global electronics industry, countries are actively seeking their own development advantages to gain a competitive edge in the market. As a crucial link in the electronics manufacturing industry, China has demonstrated strong competitiveness in the international market thanks to its low production costs, high efficiency, and rapid product iteration capabilities. However, the pressure holding process, a key step in ensuring product quality and performance during electronic product manufacturing, faces numerous challenges.

[0003] In production environments lacking advanced auxiliary tools, the pressure holding operation of electronic products often relies on traditional manual clamping with vises. This method is not only inefficient but also makes it difficult to guarantee product yield, failing to meet the demands of large-scale mass production. Furthermore, due to the uncontrollable factors of manual operation, the quality consistency of products within the same batch cannot be guaranteed, posing significant challenges to the company's quality control and cost management.

[0062] This invention is widely used in various jigs and fixtures and automated equipment. It is easy to operate, saves a lot of time, and reduces the chance of employees making mistakes, thereby greatly improving processing efficiency and saving processing costs.

[0063] 1. Fixture usage: The quick-pressing and pressure-holding jig for electronic products ensures high and stable repeated clamping and positioning accuracy when fixing and installing pressure-holding products. It uses the center of the product as a fixed reference and always uses the fixed reference of the jig as the center. The center of the two products fits into the center of the jig, realizing the function of automatic positioning. The operator does not need to worry about whether it is placed in place, which greatly improves the efficiency of manual labor and saves half of the material unloading time.

[0064] 2. Regarding product clamping accuracy: The rapid up-and-down pressing and holding fixture can align the theoretical center of the product with the theoretical center of the fixture. This solves the problem of product center offset caused by improper manual operation during traditional manual visual positioning, which leads to increased product defects during clamping and alignment. For electronic products, the rapid up-and-down pressing and holding fixture only needs to be placed in the guide limit groove, and it can automatically fit and clamp under the action of the cylinder. This saves a lot of time and cost of manual alignment and reduces product inconsistencies caused by operators, resulting in product defects.

[0065] 3. In terms of assembly and maintenance: The components of the mechanism have simple structures, and all accessories can be directly processed using CNC, milling machines and grinding machines. Precision is easy to control, and fixtures can be made quickly and maintenance cycles are short.

[0066] 4. In terms of versatility: The entire structure is clearly hierarchical, and the fixtures can be made into universal parts. When changing to similar products, only the intermediate body needs to be made, which can greatly save costs and eliminate the need for the entire set to be made.

[0067] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
