Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of middle frame detection, in particular to a fully automatic high-precision detection device for mobile phone middle frame rivets. Background Art
[0002] A mobile phone's midframe is the core support structure of the phone, typically made of metal or high-strength plastic. It supports internal components such as the motherboard, battery, and camera, and provides overall mechanical stability. The design of the midframe not only affects the durability and strength of the phone, but also significantly influences its appearance and feel. A high-quality midframe effectively protects internal components from impact while tightly fitting the outer shell and screen to ensure optimal functionality and appearance. Mobile phone midframe rivets are the fixing components used to connect the various parts of the phone's midframe. They are typically made of metal and ensure the stability and durability of the phone's structure. During the phone manufacturing process, rivets tightly secure the midframe to other internal components, enhancing overall mechanical strength and helping to maintain the consistency of the phone's appearance.
[0003] However, errors are inevitable in the production process of mobile phone middle frames, which may cause the rivets of the mobile phone middle frames to be too high or offset. Unqualified mobile phone middle frames will damage the screen and other components when the mobile phone is assembled. At this time, a visual inspection instrument is needed to perform high-precision inspection of the mobile phone middle frame. During the inspection, the staff needs to place the mobile phone middle frames one by one under the visual inspection instrument for inspection. The middle frames can only be taken out and loaded after the inspection of the previous middle frame is completed, which reduces the loading speed and work efficiency. At the same time, the visual data stored by the visual inspection instrument is fixed within a certain range. If there is an offset when placing the mobile phone middle frame, it will lead to missed detection or detection errors, thereby reducing the detection accuracy. Utility Model Content

A worm 7 is engaged with one side of the worm wheel 6. When the worm 7 rotates, it engages the worm wheel 6 to rotate, so that the worm wheel 6 drives the rotating ring 4 to rotate on the outer surface of the fixed column 5. A carrier plate 8 is provided above the adjustment structure 3. The adjustment structure 3 facilitates adjustment of the rotation angle of the carrier plate 8. Four groups of placement seats 9 are fixedly connected to the upper surface of the carrier plate 8. A group of middle frame bodies 10 are respectively provided on the upper surface of each group of placement seats 9. The placement seats 9 are convenient for placing the middle frame bodies 10.

The fixed structure 11 includes a sliding block 12, a positive and negative threaded rod 13 and a clamping plate 14. There are two groups of sliding blocks 12, and the two groups of sliding blocks 12 are slidably connected to the inside of the slide groove on the upper surface of the placement seat 9. A threaded hole is provided at one end of the two groups of sliding blocks 12, and the positive and negative threaded rod 13 is threadedly connected to the threaded hole at one end of the two groups of sliding blocks 12. The upper surfaces of the two groups of sliding blocks 12 are fixedly connected with a clamping plate 14, and the two groups of clamping plates 14 are respectively located on both sides of the middle frame 10. The fixed structure 11 facilitates the fixation of the middle frame 10.
[0021] In the specific implementation process, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, two groups of mounting plates 15 are fixedly connected to the upper surface of the detection platform 1, and through holes are opened on the side surfaces of the two groups of mounting plates 15. Four groups of support columns 16 are fixedly connected to the lower surface of the detection platform 1, and the support columns 16 provide a stable supporting force for the detection platform 1.
[0022] Among them, the lower end of the fixed column 5 is fixedly connected to the upper surface of the detection platform 1, and the fixed column 5 plays the role of rotatably installing the rotating ring 4 on the upper surface of the detection platform 1. The upper end of the rotating ring 4 is fixedly connected to the lower surface of the supporting plate 8. When the rotating ring 4 rotates on the outer surface of the fixed column 5, it can drive the supporting plate 8 to rotate.
[0023] Among them, the two ends of the worm 7 are rotatably connected to the inside of the through holes on the side surfaces of the two groups of mounting plates 15. The mounting plates 15 play the role of mounting the worm 7 on the upper surface of the detection platform 1. A servo motor 17 is provided at one end of the worm 7. The servo motor 17 is electrically connected to an external power supply. The power output end of the servo motor 17 is fixedly connected to one end of the worm 7. The bottom of the servo motor 17 is fixedly connected to the upper surface of the detection platform 1. The servo motor 17 is controlled to start, and the rotation of the power output end of the servo motor 17 drives the worm 7 to rotate.
[0024] Among them, a through hole is provided on the outer surface of the mounting seat 9, and the through hole on the outer surface of the mounting seat 9 is connected to the slide groove on the upper surface of the mounting seat 9. One end of the positive and negative screw rods 13 is rotatably connected to the inner wall of the slide groove on the upper surface of the mounting seat 9, and the other end of the positive and negative screw rods 13 passes through the through hole on the outer surface of the mounting seat 9 and extends to the outer surface of the mounting seat 9. The positive and negative screw rods 13 can rotate inside the through hole on the outer surface of the mounting seat 9, and the positive and negative screw rods 13 extend to the outer surface of the mounting seat 9 and are fixedly connected to the rotating wheel 18. The rotating wheel 18 is convenient for the operator to hold and rotate the positive and negative screw rods 13. The threaded holes at one end of the two sets of sliding blocks 12 are respectively located at the positive and negative teeth on the outer surfaces of the positive and negative screw rods 13. When the positive and negative screw rods 13 rotate, the positive and negative teeth on the outer surfaces of the positive and negative screw rods 13 are respectively threadedly connected to the threaded holes at one end of the two sets of sliding blocks 12, so that the two sets of sliding blocks 12 extend to the slide groove on the upper surface of the mounting seat 9 and slide close to or away from each other.
[0025] Among them, the clamping plate 14 is fixedly connected to the side close to the middle frame body 10 with a rubber pad 19, and the rubber pad 19 is attached to the outer surface of the middle frame body 10 away from the clamping plate 14. The rubber pad 19 prevents the clamping plate 14 from directly and rigidly contacting the middle frame body 10, and prevents the clamping plate 14 from scratching the middle frame body 10. The rubber pad 19 is attached to the side of the outer surface of the middle frame body 10 with a serrated anti-skid groove. The serrated anti-skid groove on one side of the rubber pad 19 increases the friction between the rubber pad 19 and the middle frame body 10, so that the clamping plate 14 can clamp the middle frame body 10 more tightly.
[0026] The working principle provided by the present invention is as follows: when it is necessary to perform rivet inspection on the middle frame body 10, the operator first places the middle frame body 10 on the upper surface of the placement seat 9, the operator holds and rotates the rotating wheel 18, and when the rotating wheel 18 rotates, it drives the positive and negative threaded rods 13 to rotate. When the positive and negative threaded rods 13 rotate, the positive and negative threads on the outer surfaces of the positive and negative threaded rods 13 are respectively threadedly connected with the threaded holes at one end of the two sets of sliding blocks 12, so that the two sets of sliding blocks 12 extend to the slide grooves on the upper surface of the placement seat 9 and slide close to each other. When the two sets of sliding blocks 12 approach each other, the clamping plates 14 on both sides of the middle frame body 10 are driven to approach each other, so that the rubber pads 19 on one side of the clamping plates 14 are attached to the outer surfaces of both sides of the middle frame body 10, so that the middle frame body 10 is fixed in the specified position. , to prevent the placement position of the middle frame 10 from being offset. After the inspection of the middle frame 10 is completed, the operator can hold the reversing wheel 18 to reverse the positive and negative screws 13. At this time, the sliding blocks 12 are away from each other, thereby causing the rubber pad 19 to separate from the middle frame 10, making it convenient for the operator to remove the middle frame 10. When the inspection of the previous middle frame 10 is completed, the servo motor 17 can be controlled to start. The power output end of the servo motor 17 rotates to drive the worm 7 to rotate. When the worm 7 rotates, it engages the worm gear 6 to rotate, so that the worm gear 6 drives the rotating ring 4 to rotate on the outer surface of the fixed column 5. When the rotating ring 4 rotates, it drives the bearing plate 8 to rotate. When the bearing plate 8 rotates, the next middle frame 10 is rotated to the bottom of the visual inspection instrument 2 for inspection.
