Technical Field
[0001] This utility model relates to the field of welding equipment technology, and in particular to a spot welding fixture for a mobile phone lens cover plate. Background Technology
[0002] A mobile phone lens cover is a metal protective component that covers the outside of a mobile phone camera lens. It serves to secure multiple camera lenses, flash, and other components on the back of the phone, while also enhancing the phone's aesthetics and brand recognition. Some mobile phone lens covers require copper sheets to be welded to a raised structure on the inner surface. On one hand, the copper sheets can quickly conduct static electricity generated by the lens module and surrounding components to the metal cover and then ground, preventing static damage to the phone's delicate components. On the other hand, copper's excellent thermal conductivity allows it to conduct heat generated by components such as the image stabilization motor in the lens module to the metal cover, facilitating heat dissipation.
[0003] Currently, the welding of copper sheets to the metal cover plates of mobile phone lenses generally employs laser spot welding. This process uses the instantaneous energy of a focused laser beam to locally melt the contact points between the copper sheet and the metal cover plate, forming tiny weld nuggets and achieving a metallurgical bond. However, laser spot welding requires positioning and fixing the metal cover plate to ensure it is in the correct position, preventing movement or shaking, and ensuring accurate weld placement. Therefore, it is necessary to provide a spot welding fixture for mobile phone lens cover plates. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a spot welding fixture for mobile phone lens cover plates, which can position and fix the metal cover plates of mobile phone lenses, ensuring that the metal cover plates of mobile phone lenses are in the correct position and that the position of the welding points is accurate.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A spot welding fixture for a mobile phone lens cover includes a base, an upper cover plate, a pressure plate, and a cylinder arranged sequentially from bottom to top. The base has multiple receiving grooves and multiple guide sleeves. The receiving grooves are used to hold the lens cover product, and the bottom of the receiving grooves has positioning bosses that match the holes in the lens cover product. The guide sleeves are vertically fixed to the edge of the base. The upper cover plate has positioning grooves and multiple guide posts. The bottom of the positioning grooves has multiple guide through holes corresponding to the welding parts of the lens cover product. The guide posts are vertically fixed to the edge of the upper cover plate and match the guide sleeves. The shape of the pressure plate matches the shape of the positioning grooves, and the pressure plate has... Multiple clamping components and welding through holes are provided, corresponding to the guide through holes. The bottom of the clamping components is used to pass through the guide through holes and press the copper sheet to be welded onto the welding part of the lens cover product. The welding through holes are used to allow the laser beam to pass through. The output end of the cylinder is connected to the pressure plate, which is used to drive the pressure plate to move linearly back and forth in the up and down direction. Specifically, the cylinder is vertically installed on the corresponding laser welding worktable and is located outside the pressure plate. The piston rod output end of the cylinder is equipped with a connecting frame, which is fixedly connected to the pressure plate. When the cylinder is working, its piston rod moves linearly back and forth in the up and down direction, thereby driving the pressure plate to move linearly back and forth in the up and down direction through the connecting frame.
[0007] In some embodiments, the pressure plate is provided with a plurality of mounting holes and a first screw hole corresponding to the clamping assembly. The two opposite inner sidewalls of the mounting holes are provided with a first limiting step, and the first screw hole is located on one side of the mounting hole. The clamping assembly includes a pressure block, a fixing plate and a first screw. The pressure block is provided with a second limiting step and a pressure plate. The second limiting step is located on the two opposite outer sidewalls of the upper part of the pressure block. The pressure plate is vertically arranged and fixed on one side of the outer wall of the pressure block. It is used to press the copper sheet to be welded onto the welding part of the lens cover product. The bottom of the pressure block and the pressure plate protrudes through the mounting hole. The second limiting step presses on the first limiting step. The fixing plate is provided with a connecting through hole that matches the first screw hole. The fixing plate is located on the upper end face of the mounting hole. The first screw passes through the connecting through hole and is threadedly connected to the first screw hole.
[0008] In some embodiments, the guide through hole includes a connecting guide through hole for the pressure block and pressure plate and a guide through hole for the copper sheet. The shape of the guide through hole for the pressure block and pressure plate matches the shape of the pressure block and pressure plate, and the shape of the guide through hole for the copper sheet matches the shape of the copper sheet.
[0009] Compared with the prior art, this utility model achieves at least the following beneficial effects:
[0010] The lens cover is placed in the receiving groove, and the positioning boss positions it. The upper cover is placed on the base, and the guide post is inserted into the guide sleeve for precise guidance. The guide through hole on the upper cover is aligned with the welding part on the lens cover. The assembled base and upper cover are placed on the laser welding worktable and below the pressure plate. The pressure plate is located below the laser welding machine and is driven by a cylinder to move downward and press into the positioning groove of the upper cover. The pressure plate provides downward pressure to the upper cover and base, fixing them to the worktable. At the same time, the clamping component and welding through hole on the pressure plate are aligned with the guide through hole on the upper cover, allowing the bottom of the clamping component to pass through the guide through hole and press the copper sheet to be welded onto the welding part of the lens cover. The laser beam of the laser welding machine instantly irradiates the copper sheet through the welding through hole and guide through hole, melting the contact point between the copper sheet and the metal cover of the mobile phone lens to form a tiny weld nugget, thus achieving welding. This invention can position and fix the metal cover plate of a mobile phone lens, ensuring that the metal cover plate of the mobile phone lens is in the correct position and that the position of the solder joint is accurate.

[0018] like Figures 1-4 As shown in the figure, the spot welding fixture for the mobile phone lens cover provided in this application embodiment includes a base 1, an upper cover plate 2, a pressure plate 3 and a cylinder arranged sequentially from bottom to top. The cylinder is not shown in the figure.
[0019] The base 1 has multiple receiving grooves 4 and multiple guide sleeves 5. The receiving grooves 4 are used to place the lens cover plate product 90, and the bottom of the receiving groove 4 has a positioning boss 41 that matches the hole position of the lens cover plate product 90. The guide sleeves 5 are vertically fixed to the edge of the base 1. The upper cover plate 2 has a positioning groove 6 and multiple guide posts 7. The bottom of the positioning groove 6 has multiple guide through holes 61 that correspond to the welding parts of the lens cover plate product 90. The guide posts 7 are vertically fixed to the edge of the upper cover plate 2 and match the guide sleeves 5. The shape of the pressure plate 3 matches the shape of the positioning groove 6, and the pressure plate 3 has multiple guide through holes 61 that correspond to the guide through holes 61. The clamping assembly 8 and the welding through hole 9 are used. The bottom of the clamping assembly 8 is used to pass through the guide through hole 61 and press the copper sheet 100 to be welded onto the welding part of the lens cover plate product 90. The welding through hole 9 is used to allow the laser beam to pass through. The output end of the cylinder is connected to the pressure plate 3, which is used to drive the pressure plate 3 to move linearly back and forth in the up and down direction. Specifically, the cylinder is vertically installed on the corresponding laser welding worktable and is located outside the pressure plate 3. The piston rod output end of the cylinder is equipped with a connecting frame, which is fixedly connected to the pressure plate 3. When the cylinder is working, its piston rod moves linearly back and forth in the up and down direction, thereby driving the pressure plate 3 to move linearly back and forth in the up and down direction through the connecting frame.
[0020] In use, the lens cover plate 90 is placed in the receiving groove 4, and the positioning boss 41 positions the lens cover plate 90. The upper cover plate 2 is placed on the base 1, and the guide post 7 is inserted into the guide sleeve 5 for precise guidance. The guide through hole 61 on the upper cover plate 2 is aligned with the welding part on the lens cover plate 90. The assembled base 1 and upper cover plate 2 are placed on the laser welding worktable and located below the pressure plate 3. The pressure plate 3 is located below the laser welding machine. The pressure plate 3 is driven downward by a cylinder and presses into the positioning groove 6 of the upper cover plate 2. The pressure plate 3 then moves upward. The cover plate 2 and the base 1 provide downward pressure, fixing the upper cover plate 2 and the base 1 to the worktable. At the same time, the clamping component 8 and the welding through hole 9 on the pressure plate 3 are aligned with the guide through hole 61 on the upper cover plate 2, so that the bottom of the clamping component 8 can pass through the guide through hole 61 and press the copper sheet 100 to be welded onto the welding part of the lens cover plate product 90. The laser beam of the laser welding machine irradiates the copper sheet 100 instantly through the welding through hole 9 and the guide through hole 61, causing the contact point between the copper sheet 100 and the lens cover plate product 90 to melt and form a tiny weld nugget, thus achieving welding.
[0021] Specifically, the pressure plate 3 is provided with a plurality of mounting holes 10 and first screw holes 20 corresponding to the clamping assembly 8. The two opposite inner sidewalls of the mounting holes 10 are provided with first limiting steps 101, and the first screw holes 20 are located on one side of the mounting holes 10. The clamping assembly 8 includes a pressure block 81, a fixing plate 82 and a first screw 83. The pressure block 81 is provided with a second limiting step 811 and a pressure plate 812. The second limiting step 811 is located on the two opposite outer sidewalls of the upper part of the pressure block 81. The pressure plate 812 is vertically arranged and fixed to one side of the outer wall of the pressure block 81. The fixing plate 82 is provided with a connecting through hole 821 that matches the first screw hole 20. The fixing plate 82 is located on the upper end face of the mounting holes 10. The first screw 83 passes through the connecting through hole 821 and is threadedly connected to the first screw hole 20. It should be noted that the bottom of the pressure block 81 and the pressure plate 812 protrudes through the mounting hole 10, and the second limiting step 811 of the pressure block 81 presses on the first limiting step 101. Since the fixing plate 82 is fixedly connected to the pressure plate 3 by the first screw 83 and is located on the upper end face of the mounting hole 10, it can restrict the upward movement of the pressure block 81 and the pressure plate 812. The pressure plate 812 is set vertically and has a small cross-sectional area, which can ensure the pressing of the copper sheet 100 and avoid large-area obstruction of the spot welding area of the copper sheet 100.
[0022] The guide through hole 61 includes a connecting guide through hole 611 for the pressure block and a guide through hole 612 for the copper sheet. The shape of the guide through hole 611 for the pressure block and the pressure plate matches the shape of the pressure block 81 and the pressure plate 812. The shape of the guide through hole 612 for the copper sheet matches the shape of the copper sheet 100. Before laser spot welding, by setting the guide through hole 612 for the copper sheet, the copper sheet 100 can be accurately placed at the welding position of the lens cover plate product 90. Then, the laser welding machine is used for welding. The laser beam is focused on the copper sheet 100 through the welding through hole 9 and the guide through hole 612 for welding.
[0023] The edge of the pressure plate 3 is vertically fixed with a downward protruding positioning post 30; the upper cover plate 2 is provided with a positioning hole 40 corresponding to the positioning post 30. The positioning post 30 and the positioning hole 40 cooperate to ensure that the pressure plate 3 is accurately pressed into the positioning groove 6 of the upper cover plate 2.
[0024] The base 1 has countersunk screw holes 50 at both ends of its edge; the guide sleeve 5 has an external thread 51 and an annular shoulder 52. The external thread 51 is located at the lower part of the guide sleeve 5, and the annular shoulder 52 is located below the external thread 51. The guide sleeve 5 is threadedly connected to the countersunk screw hole 50 through the external thread 51.
[0025] The guide post 7 is located at the bottom of the upper cover plate 2. The upper end of the guide post 7 is provided with a second screw hole 71, and the lower end is hemispherical, which is conducive to insertion into the guide sleeve 5. The top of the upper cover plate 2 is provided with a connecting post 60 and a second screw 70 corresponding to the guide post 7. The connecting post 60 is provided with a countersunk hole 601. The guide post 7 and the upper cover plate 2 are fixedly connected by the connecting post 60 and the second screw 70. Specifically, the second screw 70 is passed through the countersunk hole 601 and the upper cover plate 2 in sequence and then threadedly connected to the second screw hole 71.
[0026] The receiving groove 4 has pick-and-place grooves 80 at both ends, which are connected to the receiving groove 4, and the depth of the pick-and-place groove 80 is greater than the depth of the receiving groove 4. The operator inserts his hand into the pick-and-place groove 80 to easily pick up the lens cover plate product 90.
[0027] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
