Description

Technical Field

[0001] This utility model relates to the technical field of a device for detecting three types of damage to a mobile phone frame, and particularly to a device for detecting three types of damage to a mobile phone frame. Background Technology

[0002] With social development and the rapid iteration of the smartphone industry, the quality of the phone's mid-frame, as a key structural component connecting the screen and the back cover, directly affects the overall performance and appearance of the phone. Conducting "three-damage" (scratches, dents, and cracks) inspections on the phone's mid-frame can effectively screen out unqualified products, prevent mid-frames with quality defects from entering the subsequent assembly process, thereby improving the pass rate of finished phones, reducing after-sales repair costs, and ensuring the user experience.

[0003] Existing methods for detecting three defects in mobile phone frames mostly rely on manual operation. Inspectors need to manually place the frame under the camera and take images from different angles for inspection. This method is problematic because it is difficult to keep the frame position consistent during manual placement, which can lead to shooting angle deviations and unstable inspection results. Furthermore, manual operation requires repeated adjustments to the frame's posture, which is cumbersome, consumes a lot of manpower, and reduces inspection efficiency, making it difficult to meet the needs of large-scale production.

Two upper and lower internal clamping blocks are slidably mounted on the front end of the rotating block. The bidirectional lead screw is threaded through the two clamping blocks. A cross groove is formed on the top of the bidirectional lead screw.

[0009] Preferably, the middle frame body is clamped between the two clamping blocks.

[0013] This utility model provides a device for detecting three defects in the mid-frame of a mobile phone, which has the following beneficial effects:

[0014] (1) Compared with the prior art, the mobile phone mid-frame three-damage detection device is equipped with a translation groove 1, a translation groove 2, an upper arc groove, a lower arc groove, a roller and a drive screw. In use, the drive motor drives the drive screw to rotate, which causes the support rod to drive the roller to move along the groove. The arc trajectory of the arc groove realizes the automatic flipping of the connecting rod and the clamping component. There is no need to manually adjust the posture of the mid-frame, which solves the problem of cumbersome manual flipping of the mid-frame in the prior art.

[0026] 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.

[0027] Depend on Figures 1-9As shown, this utility model provides a mobile phone mid-frame three-damage detection device, including a base 1. A back plate 2 and a support frame 3 are fixedly connected to the top of the base 1. The back plate 2 is fixed to the base 1 by bolts. The support frame 3 adopts a rectangular frame structure with reserved sliding space inside. The back plate 2 is located at the front end of the support frame 3, so that the shooting direction of the camera 6 is precisely aligned with the detection surface of the mid-frame body 9. A support rod 4 is slidably installed inside the support frame 3. The bottom of the support rod 4 cooperates with the drive screw 11 to achieve horizontal movement, and the top is connected to the connecting rod 7 through a bearing. The top of the support rod 4 rotates... The clamping component 5 is mounted on the middle frame 9. The clamping component 5 is fixed to the connecting rod 7 by the rotating block 501 and can rotate synchronously with the connecting rod 7 to achieve multi-angle flipping of the middle frame body 9. The middle frame body 9 is mounted on the front end of the clamping component 5. The middle frame body 9 is kept stable by the clamping force of the clamping block 503 to avoid shaking during shooting. Three cameras 6 are fixedly connected to the front end of the outer wall of the back plate 2. The three cameras 6 are respectively installed at the shooting positions of the front, side and back of the middle frame. The lens focal length is calibrated and can clearly capture the fine scratches, dents and cracks on the surface of the middle frame.

[0028] The front end of the back plate 2 is provided with a first translation groove 201, a second translation groove 202, an upper arc groove 203, and a lower arc groove 204. The inner walls of these grooves are smooth and burr-free, ensuring smooth movement of the roller 8. The first translation groove 201 and the second translation groove 202 are symmetrically distributed on both sides of the front end of the back plate 2. The groove width matches the diameter of the roller 8, providing horizontal guidance for the roller 8. The upper arc groove 203 and the lower arc groove 204 are symmetrically distributed vertically on the front end of the back plate 2. Their arc curvature has been calculated to allow the middle frame body 9 to rotate precisely 90°. The left side of the upper arc groove 203 and the lower arc groove 204 is connected to the right side of the first translation groove 201, and the right side of the upper arc groove 203 and the lower arc groove 204 is connected to the left side of the second translation groove 202, forming a complete loop trajectory to ensure that the roller 8 can move cyclically.

[0029] A connecting rod 7 is rotatably mounted on the top of the support rod 4. One end of the connecting rod 7 is connected to the support rod 4 via a bearing to achieve 360° rotation, and the other end is fixed to the rotating block 501. A clamping assembly 5 is fixedly connected to the front end of the connecting rod 7. The connection strength is ensured by welding to prevent loosening after long-term use. A roller 8 is fixedly connected to the rear end of the connecting rod 7. The roller 8 is a cylindrical structure with a polished surface. It can roll along the groove and reduce frictional resistance. The movement of the roller 8 drives the connecting rod 7 to move synchronously.

[0030] Depend on Figures 5-6As shown, this utility model provides a device for detecting three types of damage to a mobile phone frame. The clamping assembly 5 includes a rotating block 501, a bidirectional lead screw 502, a clamping block 503, and a cross groove 504. The rotating block 501 is fixedly connected to the front end of the connecting rod 7. The rotating block 501 has a sliding guide rail inside to provide movement guidance for the clamping block 503. The bidirectional lead screw 502 is rotatably mounted on the front end of the rotating block 501. The threads at both ends of the bidirectional lead screw 502 are opposite, which can drive the two clamping blocks 503 to move closer or further away synchronously. Two clamping blocks 503 are slidably mounted on the front end of the rotating block 501, which are distributed vertically. The inner side of the clamping block 503 is attached with a flexible rubber pad, which can enhance the clamping friction and avoid damaging the surface of the frame body 9. The threads of the bidirectional lead screw 502 pass through the two clamping blocks 503, and the clamping blocks 503 are precisely displaced through the thread transmission. The top of the bidirectional lead screw 502 has a cross groove 504, which is compatible with a standard screwdriver, making it easy for the operator to quickly adjust the clamping distance.

[0031] Depend on Figures 5-6 As shown, this utility model provides a mobile phone mid-frame three-damage detection device. The mid-frame body 9 is clamped between two clamping blocks 503. The clamping force of the clamping blocks 503 can be precisely controlled by the bidirectional lead screw 502 to ensure that the mid-frame body 9 will neither loosen or shift, nor deform due to excessive clamping.

[0032] Depend on Figure 7 As shown, this utility model provides a device for detecting three defects in a mobile phone frame. A baffle 12 is rotatably installed at the connection points of translation groove 1 (201), upper arc groove 203, and lower arc groove 204, and at the connection points of translation groove 2 (202), upper arc groove 203, and lower arc groove 204. The baffle 12 is made of wear-resistant plastic and can be opened and closed by rotating a pin. The two baffles 12 face opposite directions, respectively guiding the roller 8 to enter the upper arc groove 203 on its outward journey and to enter the lower arc groove 204 on its return journey. Two movable grooves 13 are provided inside the back plate 2, providing space for the movement of the support plate 14. The outer wall of the plate 12 is fixedly connected to the support plate 14. The support plate 14 and the baffle 12 are integrally formed and can move synchronously. The support plate 14 is located inside the corresponding moving groove 13. The edge of the support plate 14 is clearance-fitted with the inner wall of the moving groove 13 to ensure smooth sliding. A spring 15 is fixedly installed inside the moving groove 13. The spring 15 is a compression spring. In the initial state, it pushes the support plate 14 to keep the baffle 12 at the intersection of the grooves. The other end of the spring 15 is fixedly installed on the outer wall of the support plate 14. When the roller 8 passes through, the spring 15 can push the baffle 12 to automatically reset.

[0033] Depend on Figures 7-8As shown, this utility model provides a mobile phone frame three-damage detection device. The inner walls of translation groove 1 201 and translation groove 2 202 are both provided with slots 16. The size of the slots 16 matches the baffle 12. When the roller 8 passes through, the baffle 12 can be completely retracted into the slots 16 to avoid obstructing the movement of the roller 8.

[0034] Depend on Figure 5 As shown, this utility model provides a mobile phone frame three-damage detection device. A drive motor 10 is fixedly installed on the outer wall of the support frame 3. The drive motor 10 is a servo motor, which can accurately control the speed and direction. A drive screw 11 is rotatably installed inside the support frame 3. The drive screw 11 adopts a ball screw structure, which has high transmission efficiency and accurate positioning. The output end of the drive motor 10 is fixedly connected to one end of the drive screw 11, and the power transmission is realized through a coupling. The bottom of the support rod 4 is threaded to the outer wall of the drive screw 11. When the drive screw 11 rotates, the support rod 4 can make linear reciprocating motion along the support frame 3.

[0035] Working principle: During use, the operator places the mid-frame body 9 to be tested between the two clamping blocks 503, inserts a screwdriver into the cross groove 504 at the top of the bidirectional lead screw 502 and rotates it. The bidirectional lead screw 502 drives the two clamping blocks 503 to move relative to each other along the sliding guide rail of the rotating block 501 through threaded transmission until the flexible rubber pads on the inner side of the clamping blocks 503 are tightly attached to the mid-frame body 9, completing the firm fixation of the mid-frame. At this time, the front of the mid-frame body 9 is facing upwards and is on the same vertical line as the camera 6 at the top front of the back plate 2. The camera 6 automatically starts to take pictures of the front of the mid-frame, such as... Figure 1 As shown.

[0036] When the drive motor 10 is started, its output power drives the drive screw 11 to rotate clockwise via the coupling. Since the bottom of the support rod 4 is threadedly connected to the drive screw 11, the support rod 4 moves horizontally to the right along the internal guide rail of the support frame 3. Simultaneously, the roller 8 at the rear end of the connecting rod 7 is embedded in the translation groove 201 and rolls to the right along the translation groove 201 in sync with the support rod 4. When the roller 8 moves to the intersection of the translation groove 201 and the upper arc groove 203, the left-side baffle 12, under the elastic force of the spring 15, is in a position... In the tilted support state, roller 8 is guided by baffle 12 into the upper arc groove 203. Roller 8 continues to move along the arc trajectory of the upper arc groove 203, driving the rotating block 501 and clamping assembly 5 to rotate upward around the bearing at the top of the support rod 4 via connecting rod 7. During this process, the middle frame body 9 rotates synchronously with the clamping assembly 5. When roller 8 moves to the middle section of the upper arc groove 203, the middle frame body 9 rotates exactly 90°, with its side facing upward and aligned with the camera 6 on the front side of the back plate 2. The camera 6 immediately starts capturing an image of the side of the middle frame, as shown in the image. Figure 2 As shown.

[0037] As the support rod 4 continues to move to the right, the roller 8 rolls along the lower slope of the upper arc groove 203. The middle frame body 9 flips due to its own weight. When the roller 8 reaches the intersection of the upper arc groove 203 and the second translation groove 202, the middle frame body 9 has completed a 180° flip, with its back facing upwards. At this point, the roller 8 contacts the right-side baffle 12. With the continuous pushing force of the support rod 4, the baffle 12 compresses the spring 15 in the translation groove 13 through the support plate 14, gradually retracting into the slot 16 on the inner wall of the second translation groove 202. The channel between the upper arc groove 203 and the second translation groove 202 is fully opened, and the roller 8 smoothly enters the second translation groove 202 and moves to the right along it. The back of the middle frame body 9 aligns with the camera 6 at the bottom front of the back plate 2. The camera 6 then starts capturing an image of the back. Figure 3 As shown.

[0038] After the back side inspection is completed, the drive motor 10 receives a reversal signal, drives the lead screw 11 to rotate counterclockwise, the support rod 4 moves back to the left along the support frame 3, and the roller 8 rolls to the left along the translation groove 202. When it reaches the intersection of the translation groove 202 and the lower arc groove 204, the right side baffle 12 pops out of the slot 16 under the return force of the spring 15, guiding the roller 8 into the lower arc groove 204. The roller 8 moves along the arc trajectory of the lower arc groove 204, causing the middle frame body 9 to flip downward. During the process, the other side of the middle frame body 9 gradually faces upward. When the roller 8 moves to the middle section of the lower arc groove 204, this side is aligned with the camera 6 at the corresponding position. The camera 6 starts to capture the image of the other side, such as... Figure 4 As shown.

[0039] The support rod 4 continues to move to the left, and the roller 8 rolls down the slope of the lower arc groove 204 to the intersection with the translation groove 201. At this time, the roller 8 pushes the left baffle 12 to compress the spring 15 and retracts into the slot 16. After entering the translation groove 201, the roller 8 continues to move to the left until the support rod 4 returns to its initial position, and the drive motor 10 stops running. Figure 1 As shown.

[0040] The operator rotates the bidirectional lead screw 502 in the opposite direction to loosen the clamping block 503 from the middle frame body 9, removes the middle frame that has been inspected, and the entire inspection process is completed. The device can then immediately proceed to inspect the next middle frame body 9.
