Description

Technical Field

[0001] This utility model is applied to the field of product pressing, and in particular relates to an assembly fixture opening and closing mechanism. Background Technology

[0002] With the rapid development of manufacturing technology, consumers are increasingly demanding higher product quality, especially in the consumer electronics sector, such as the mobile phone industry. To enhance product competitiveness, manufacturers are constantly introducing new processes to improve product quality. Waterproofing has become one of the most important performance indicators for electronic products like mobile phones. To achieve waterproofing, many internal components of a mobile phone need to be tightly bonded using adhesive technology and then allowed to cure after bonding. During the curing process, to ensure a complete seal between components, a certain amount of pressure needs to be applied and maintained for a period of time.

[0003] However, traditional manual assembly methods have many shortcomings, such as low precision, low efficiency, and difficulty in guaranteeing quality. In order to meet the market's demand for high quality, high precision, and high efficiency, customers urgently need to develop jigs and automatic jig opening and closing mechanisms that can assist in product assembly.

[0004] Currently, the common practice is to separate product assembly and fixture opening / closing into two independent workstations. This approach is not only complex but also lacks stability, making it difficult to maintain consistent quality. Therefore, designing a mechanism capable of automatic opening / closing, precise positioning, and fixture fixing is particularly important. This mechanism should be able to drive the cover module to move back and forth, keeping the product in a fixed position, thereby simplifying the process and improving stability and quality.

[0005] Therefore, based on the above problems, if an automatic opening and closing mechanism for assembly fixtures could be designed, this mechanism could precisely position and fix the fixture, and drive the cover module to move back and forth via a drive component, allowing the cover module to push the product to a fixed position. This opening and closing structure is simple, compact, and highly precise, providing reliable technical support for mass production, standardization, and professional automation of assembly. It can effectively solve the aforementioned problems. Summary of the Invention
