Description

Technical Field

[0001] This utility model relates to the field of mobile phone repair, specifically a multi-functional clamp with built-in heating function. Background Technology

[0002] In mobile phone motherboard repair, the clamp, as a core positioning device, directly affects repair efficiency and quality. Current mainstream technology uses a mechanical clamping block structure to hold and fix the motherboard, its functionality relying primarily on the precise adjustment of the screw drive mechanism. However, existing clamps have significant technical shortcomings in practical applications: First, insufficient functional integration complicates the operation process. Traditional clamps only have basic physical clamping functions. When performing repairs requiring heating, such as chip desoldering, repair personnel must additionally use hot air guns or infrared heating devices for assistance. This discrete operation mode not only reduces the efficiency of process connections but also increases the error rate due to frequent tool changes, especially during heat source switching, which can easily cause motherboard displacement, directly affecting soldering accuracy. Second, external heating methods have significant thermodynamic defects. When using non-contact heating methods such as hot air guns, the heat radiation range is difficult to control precisely, leading to the risk of thermal damage to sensitive components around the motherboard. Third, the adaptability of the mechanical structure limits its application range. Existing clamps generally use a fixed-spacing clamping block design, which cannot adapt to the size differences of motherboards from different brands of mobile phones. In conclusion, there is an urgent need to develop a mobile phone repair fixture with built-in integrated heating function that can flexibly adapt to different motherboards. Utility Model Content

Both the fixed clamping blocks 2 and the movable clamping block 3 are elongated and flat, and parallel to each other. The movable clamping block 3 moves close to the side of the box body 1, and the direction of movement is perpendicular to the movable clamping block 3. A moving mechanism is provided on the box body 1 to displace the movable clamping block 3. A heating area 4 is also provided on the side of the box body 1, and the heating area 4 is located on the moving path of the movable clamping block 3. A heating mechanism is provided on the inner wall of the box body 1 of the heating area 4. The heating mechanism includes a clamping plate 5 detachably fixed to the inner wall of the box body 1 via bolts. A heating plate 6 is pressed between the clamping plate 5 and the inner wall of the box body 1. Several strip-shaped limiting grooves 14 parallel to the screw 12 are also provided on the side wall of the box body 1. The movable clamping block 3 has a protrusion that engages with the limiting groove 14, and the protrusion is slidably connected in the limiting groove 14. The fixed clamping block 2 and the movable clamping block 3 have several clamping teeth 15 on their sidewalls perpendicular to the moving path of the movable clamping block 3. In this embodiment, an independent heating area 4 is provided on the fixture. This heating area 4 is centrally heated by a heating mechanism built into the fixture, eliminating the need to switch heating tools and ensuring the stability of the motherboard clamping and maintaining the welding accuracy. Secondly, the built-in centralized heating makes it easy to control the heat radiation range, avoiding the risk of heat damage to sensitive components around the motherboard and improving the repair success rate. Furthermore, the fixed clamping block 2 and the movable clamping block 3, which have adjustable spacing between them, can flexibly adapt to the size of motherboards of different brands of mobile phones, effectively enhancing the versatility of the fixture.

[0019] The moving mechanism includes a strip-shaped perforation 10 on the side of the box body 1.
