[0003]现有装置的夹持结构往往存在驱动分散的问题,多个夹持部件需独立控制,难以实现同步动作,导致对中框的夹持力度不均衡,易出现局部夹持过松或过紧的情况,影响中框检测时的稳定性
[0014] (1) Compared with the prior art, the appearance inspection device for the middle frame uses a first motor, a turntable, an inclined groove, a moving pin, a limiting pin, a clamping plate, a first sponge pad, and a second sponge pad. When the middle frame needs to be clamped and positioned, the second motor 16 is first activated so that the front of the inspection seat 1 faces upward, and then the middle frame is placed on the clamping plate 7. At this time, the first sponge pad 8 contacts the inner top of the middle frame to prevent the clamping plate 7 from directly contacting the middle frame and causing scratches on the middle frame. Then the first motor 3 drives the turntable 4 to rotate. Since the moving pin 6 is located inside the inclined groove 5, the rotation of the turntable 4 will cause the adjacent moving pins 6 to move away from each other, thereby causing the adjacent limiting pins 32 and the clamping plate 7 to move away from each other. Then the second sponge pad 8... The pad 9 contacts the inner wall of the middle frame, which also prevents the clamping plate 7 from directly contacting the inner wall of the middle frame and causing scratches on the inner wall. Then, the four clamping plates 7 fix the middle frame, and the middle frame can be inspected. Compared with the existing appearance inspection, there is often a problem of dispersed drive. Multiple clamping components need to be controlled independently, making it difficult to achieve synchronous action. This results in uneven clamping force on the middle frame, which is prone to local clamping being too loose or too tight, affecting the stability of the middle frame during inspection. This middle frame appearance inspection device can drive the four clamping plates to move synchronously, realizing synchronous and balanced clamping of the middle frame, avoiding the middle frame from shifting or tilting due to uneven force, and providing a stable clamping foundation for subsequent inspection.

[0013] This utility model provides a device for inspecting the appearance of a mid-frame, which has the following advantages:
[0014] (1) Compared with the prior art, the appearance inspection device for the middle frame uses a first motor, a turntable, an inclined groove, a moving pin, a limiting pin, a clamping plate, a first sponge pad, and a second sponge pad. When the middle frame needs to be clamped and positioned, the second motor 16 is first activated so that the front of the inspection seat 1 faces upward, and then the middle frame is placed on the clamping plate 7. At this time, the first sponge pad 8 contacts the inner top of the middle frame to prevent the clamping plate 7 from directly contacting the middle frame and causing scratches on the middle frame. Then the first motor 3 drives the turntable 4 to rotate. Since the moving pin 6 is located inside the inclined groove 5, the rotation of the turntable 4 will cause the adjacent moving pins 6 to move away from each other, thereby causing the adjacent limiting pins 32 and the clamping plate 7 to move away from each other. Then the second sponge pad 8... The pad 9 contacts the inner wall of the middle frame, which also prevents the clamping plate 7 from directly contacting the inner wall of the middle frame and causing scratches on the inner wall. Then, the four clamping plates 7 fix the middle frame, and the middle frame can be inspected. Compared with the existing appearance inspection, there is often a problem of dispersed drive. Multiple clamping components need to be controlled independently, making it difficult to achieve synchronous action. This results in uneven clamping force on the middle frame, which is prone to local clamping being too loose or too tight, affecting the stability of the middle frame during inspection. This middle frame appearance inspection device can drive the four clamping plates to move synchronously, realizing synchronous and balanced clamping of the middle frame, avoiding the middle frame from shifting or tilting due to uneven force, and providing a stable clamping foundation for subsequent inspection.
[0015] (2) Compared with the prior art, the mid-frame appearance inspection device protects the mid-frame through the first sponge pad and the second sponge pad during the clamping process by making flexible contact, thereby reducing the damage to the appearance of the mid-frame caused by the clamping operation.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0026] Depend on Figures 1 to 8 As shown, this utility model provides a mid-frame appearance inspection device, including an inspection base 1. An installation groove 2 is provided inside the inspection base 1. A first motor 3 is fixedly connected to the inner wall of the installation groove 2. A turntable 4 is fixedly connected to the output end of the first motor 3. Four inclined grooves 5 are provided on the side wall of the turntable 4. A movable pin 6 is movably installed inside the inclined groove 5. A limit pin 32 is fixedly connected to the side wall of the movable pin 6. A clamping plate 7 is fixedly connected to the side of the limit pin 32 away from the movable pin 6. A first sponge pad 8 is fixedly connected to the side wall of the clamping plate 7. When it is necessary to clamp and position the mid-frame, the second motor 16 is first activated so that the front of the inspection base 1 faces upwards, and then the mid-frame is placed... On the clamping plate 7, the first sponge pad 8 is in contact with the inner top of the middle frame to prevent the clamping plate 7 from directly contacting the middle frame and causing scratches on the middle frame. Then the first motor 3 works to drive the turntable 4 to rotate. Since the moving pin 6 is located inside the inclined groove 5, the rotation of the turntable 4 will cause the adjacent moving pin 6 to move away from each other, thereby causing the adjacent limit pin 32 and the clamping plate 7 to move away from each other. Then the second sponge pad 9 is in contact with the inner wall of the middle frame, which can also prevent the clamping plate 7 from directly contacting the inner wall of the middle frame and causing scratches on the inner wall of the middle frame. Then the four clamping plates 7 fix the middle frame. At this time, the middle frame can be inspected. The second sponge pad 9 is fixedly connected to the other side wall of the clamping plate 7.
[0027] Depend on Figures 1 to 8As shown, this utility model provides a mid-frame appearance inspection device. The inspection base 1 has a rotating groove 10 inside, with a turntable 4 located inside the rotating groove 10. A wire groove 13 is provided at the bottom of the mounting groove 2. Four first limiting grooves 11 are provided on the inner wall of the rotating groove 10, with limiting pins 32 located inside the first limiting grooves 11. The rotating groove 10 provides rotational space for the turntable 4, and the wire groove 13 provides installation space for the wires of the first motor 3. Two second limiting grooves 12 are provided inside the first limiting grooves 11. Two limiting blocks 31 are fixedly connected to the side wall of the limiting pin 32, located inside the second limiting grooves 12. The limiting blocks 31 and the second limiting grooves 12 cooperate to restrict the movement of the limiting pin 32, preventing deviation during movement. A workbench 14 is provided below the inspection base 1, with two first support plates 15 fixedly connected to the upper surface of the workbench 14. The right first support plate... A second motor 16 is fixedly connected to the side wall of the 15. A first rotating shaft 17 is fixedly connected to the output end of the second motor 16. A rotating ring 18 is fixedly connected to the end of the first rotating shaft 17 away from the second motor 16. A detection seat 1 is rotatably mounted on the inner surface of the 15. When the second motor 16 is working, it can drive the first rotating shaft 17 and the wire groove 13 to rotate, thereby driving the detection seat 1 to rotate around the first rotating shaft 17. This allows the front of the clamped middle frame to face upwards, making it easier for the detection mechanism 28 to detect whether the front of the middle frame is qualified. A third motor 19 is fixedly connected to the side wall of the rotating ring 18. A second rotating shaft 20 is fixedly connected to the output end of the third motor 19. The end of the second rotating shaft 20 away from the third motor 19 is fixedly connected to the side wall of the detection seat 1. When the third motor 19 is working, it can drive the second rotating shaft 20 and the detection seat 1 to rotate, thereby changing the orientation of the side wall of the clamped middle frame, so that the four outer edges of the middle frame can face upwards in sequence for detection by the detection mechanism 28.
[0028] Depend on Figures 1 to 8As shown, this utility model provides a mid-frame appearance inspection device. Four second support plates 21 are fixedly connected to the upper surface of the workbench 14. A fourth motor 22 is fixedly connected to the side wall of the right rear second support plate 21. A first lead screw 23 is fixedly connected to the output end of the fourth motor 22. A moving plate 24 is threadedly connected to the outer surface of the first lead screw 23. A fifth motor 25 is fixedly connected to the side wall of the moving plate 24. A second lead screw 26 is fixedly connected to the output end of the fifth motor 25. A moving seat 27 is threadedly connected to the outer surface of the second lead screw 26. A detection mechanism 28 is fixedly connected to the lower surface of the moving seat 27. The operation of the fifth motor 25 can drive the second lead screw 26 to rotate, thereby driving the moving seat 27 and the detection mechanism 28 to move forward. The fourth motor 22 can drive the first lead screw 23 to rotate, which in turn drives the moving plate 24 to move back and forth, which in turn drives the moving seat 27 and the detection mechanism 28 to move back and forth. This allows the detection mechanism 28 to move back, forth, left, and right, making it easier for the detection mechanism 28 to detect whether there are problems on the surface of the middle frame at different positions. A slide rod 29 is fixedly connected between the second support plate 21 on the left side. The moving plate 24 is sleeved on the outer surface of the slide rod 29. The slide rod 29 can restrict the movement of the moving plate 24 to prevent it from deviating during movement. Four legs 30 are fixedly connected to the lower surface of the worktable 14. The legs 30 can support the worktable 14.
