These parts are not only diverse in material, but also vary greatly in size and specifications and have complex structural features. Currently, the traditional clamping mechanisms used in the detection process are mostly rigid fixed designs, which have obvious limitations: on the one hand, due to the diverse shapes of mobile phone parts and their rapid updates, fixed fixtures are difficult to adapt to the rapid switching needs of different models, resulting in low efficiency of the inspection line; on the other hand, modern high-precision optical inspection systems have strict requirements for working distance and focal length adjustment, while traditional clamping mechanisms cannot achieve precise adjustment of the part height while maintaining stable clamping, which seriously restricts the adaptability and detection accuracy of the inspection system. Therefore, there is an urgent need for an adaptive clamping mechanism for the detection of surface defects in mobile phone parts. Utility Model Content

Detailed Implementation
[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: it includes a base 1 and a placement plate 2, with the placement plate 2 provided on the upper part of the base 1;
[0027] It also includes:
[0028] Two sliders 3 are slidably mounted in the first grooves 4 opened on the front and rear sides of the bottom wall of the base 1. An adapter 6 is rotatably mounted on the first slider 3 via a rotating shaft. A second slider 8 is slidably mounted in the second grooves 7 opened on the left and right sides of the upper part of the adapter 6. A second spring 23 is fixedly mounted on the left and right sides inside the second groove 7. One end of the second spring 23 is fixedly connected to the second slider 8. During the idle process of the clamping mechanism, the rebound thrust generated by the second spring 23 can prevent the adapter 6 from tilting during this process.
[0029] Motor 9, the motor 9 is fixedly installed on the rear side wall of the base 1, and a bidirectional lead screw 10 is fixedly installed on the output shaft of the motor 9. The bidirectional lead screw 10 is rotated through two first slide grooves 4 via bearings, and the first slider 3 is rotated on the bidirectional lead screw 10 via threads.
[0030] There are four movable rods 12, which are fixedly mounted on four second-order sliders 8. The four movable rods 12 are movably mounted in four movable slots 13 opened on the upper part of the base 1. A lifting rod 14 is movably inserted into the movable rod 12. A lifting plate 15 is fixedly mounted on the upper end of the lifting rod 14. A silicone clamping block 16 is provided on the upper part of the lifting plate 15. Several movable blocks 24 are distributed with rounded corners on the lifting rod 14. The movable blocks 24 are movably mounted in the strip grooves 25 opened on the inner wall of the movable rod 12. The movable blocks 24 can not only limit the lifting distance of the lifting rod 14 to prevent the lifting rod 14 from detaching from the movable rod 12, but also prevent the lifting rod 14 from rotating and affecting the clamping stability of the silicone clamping block 16 on the mobile phone parts.
[0031] An electric push rod 17 is fixedly installed in a fixed groove 18 opened in the middle of the upper part of the base 1. The upper end of the electric push rod 17 is fixedly connected to the placement plate 2. Guide rods 20 are fixedly installed at the four corners of the bottom of the placement plate 2. The guide rods 20 are movably inserted into the base 1. The guide rods 20 can provide auxiliary guidance for the movement of the placement plate 2, thereby effectively improving the stability of the placement plate 2.
[0032] The base 1 is provided with a centering positioning mechanism 19, which includes:
[0033] Gear 19-1 is rotatably mounted inside base 1 via a rotating shaft. Movable frames 19-9 are movably mounted on the left and right sides of the base 1. A rack 19-2 that meshes with gear 19-1 is fixedly mounted on the side wall of the movable frame 19-9. A movable rod 19-3 is fixedly mounted on one end of the movable frame 19-9. The two movable rods 19-3 are movably mounted in the movable slots 5 opened on the left and right sides of the upper part of the base 1.
[0034] The threaded limiting rod 19-4 is threaded and rotated through the left moving rod 19-3. The bottom wall of the base 1 is provided with a groove 11 that matches the lower end of the threaded limiting rod 19-4. A first spring 19-5 connected to the moving rod 19-3 is fixedly installed in the moving groove 5.
[0035] Two movable plates 19-6 are fixedly mounted on the upper ends of two movable rods 19-3 respectively. Vertical rods 19-7 are fixedly mounted on the front and rear sides of the upper part of the movable plate 19-6. The upper end of the threaded limiting rod 19-4 passes through the movable plate 19-6 and is fixedly mounted with an adjusting handle 19-8. By using the rebound thrust of the first spring 19-5 on the movable rod 19-3, and the meshing of the gear 19-1 and the two racks 19-2, the vertical rods 19-7 on the left and right sides can be used to center the mobile phone parts. A rotating cylinder 21 is rotatably mounted on the vertical rod 19-7 through a bearing. A silicone sleeve 22 is fixedly mounted on the rotating cylinder 21. The silicone sleeve 22 can prevent the mobile phone parts from directly contacting the vertical rods 19-7 and causing damage. The rotating cylinder 21 can rotate on the vertical rods 19-7 to prevent the mobile phone parts from moving back and forth during the clamping process and causing friction and wear with the vertical rods 19-7.
[0036] When using this utility model, the mobile phone part is placed on the upper part of the placement plate 2. The rebound force applied by the first spring 19-5 to the moving rod 19-3, and the meshing of the gear 19-1 and the two racks 19-2, can achieve the centering positioning of the mobile phone part on the left and right vertical rods 19-7. Then, the motor 9 is started, and the motor 9 drives the bidirectional lead screw 10 to rotate, so that the two first sliders 3 move synchronously in opposite directions. The first slider 3 drives the adapter 6 to move. The adapter 6 drives the movable rod 12 to move through the second slider 8. The movable rod 12 drives the silicone clamping block 16 to move closer to the mobile phone part through the lifting rod 14 and the lifting plate 15, so that the silicone clamping blocks 16 on the front and rear sides can clamp and fix the mobile phone part. During this process, the adapter 6 will also tilt due to the different shapes of the mobile phone part, and change the position of the second slider 8 in the second slide groove 7, so as to achieve adaptive clamping of the mobile phone part by the four silicone clamping blocks 16.
[0037] After the mobile phone parts are clamped and fixed, the vertical rod 19-7 on one side can be moved away from the mobile phone parts. By using the cooperation of the moving frame 19-9, gear 19-1, moving rod 19-3 and rack 19-2, the vertical rods 19-7 on both sides can move synchronously in opposite directions, so that the silicone sleeves 22 on both sides are disengaged from the mobile phone parts. After the threaded limit rod 19-4 moves to the position corresponding to the groove 11, the adjusting handle 19-8 can be rotated. The adjusting handle 19-8 drives the threaded limit rod 19-4 to rotate, so that the lower end of the threaded limit rod 19-4 is inserted into the groove 11, thereby limiting the moving rod 19-3. Then, the electric push rod 17 is activated. The electric push rod 17 can drive the placement plate 2 to move up and down to adjust the height of the mobile phone parts. By using the friction generated between the silicone clamping block 16 and the mobile phone parts, the silicone clamping block 16, the lifting rod 14 and the lifting plate 15 can also move up and down to keep the mobile phone parts clamped and fixed.
[0038] Compared with the prior art, the beneficial effects of this utility model are:
[0039] By setting up a bidirectional lead screw 10 driven by motor 9, and coordinating with the linkage structure of slider 3 and adapter 6, the synchronous adaptive clamping action of the silicone clamping blocks 16 on both the front and rear sides can be realized. This not only ensures the uniform distribution of clamping force, but also automatically adjusts the clamping angle according to the different shapes of mobile phone parts, effectively solving the problem of poor adaptability of traditional clamps to parts of different shapes.
[0040] The centering positioning mechanism 19 achieves automatic centering positioning of the mobile phone parts by the meshing transmission of gear 19-1 and rack 19-2, combined with the elastic reset function of spring 19-5. Furthermore, the flexible contact design of rotating cylinder 21 and silicone sleeve 22 ensures positioning accuracy while avoiding damage to the surface of the parts caused by hard contact. It is particularly suitable for the non-destructive clamping requirements of high-precision mobile phone parts.
[0041] With the cooperation of the lifting rod 14, the lifting plate 15, the silicone clamping block 16 and the electric push rod 17, the height of the mobile phone parts can be adjusted in the clamping state to adapt to the working distance required by different testing equipment.
[0042] The guide rod 20 can provide auxiliary guidance for the movement of the placement plate 2, thereby effectively improving the stability of the placement plate 2.
[0043] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
