[0013] Preferably, the second gear forms a rotating structure with the fixed plate via a second rotating shaft, and the second gear meshes with the first gear.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows: When in use, the electric push rod is activated, causing the sleeve to move. This moves the transmission gear fixedly connected to the end of the first rotating rod along the first rack, moving the inspection table into the inspection cabinet. The guide rod then slides down along the guide groove, allowing the light shield to cover the outside of the phone charger casing being inspected, preventing interaction between external light and the inspection light source. Combined with an adjustable diffuser, the incident light can be evenly scattered in all directions, creating a uniform diffuse reflection effect on the charger casing surface, reducing excessive localized reflections on the phone charger casing. Simultaneously, the four sides of the phone charger casing are cleaned during the feeding process, further improving the accuracy of the inspection. The specific method is as follows: Equipped with a feeding mechanism, cleaning mechanism, supplementary lighting, main telescopic rod, diffuse reflector, and auxiliary telescopic rod, the sleeve moves when the electric push rod is activated. This causes the transmission gear fixedly connected to the end of the first rotating rod to move along the first rack, which in turn moves the second rack along the transmission gear. This moves the testing platform into the testing cabinet, while simultaneously causing the guide rod to slide down along the guide groove. This allows the light shield to cover the outside of the mobile phone charger casing being tested, preventing external light from interacting with the testing light source and improving the accuracy of testing the mobile phone charger casing. Furthermore, by activating the supplementary light, the light is directed onto the diffuse reflector plate. With the combined action of the main telescopic rod and the auxiliary telescopic rod, the angle of the diffuse reflector plate can be adjusted, allowing the light to be reflected onto the surface of the phone charger casing. This disperses the incident light evenly in all directions, creating a uniform diffuse reflection effect on the surface of the charger casing and reducing excessive localized reflections on the phone charger casing. Simultaneously, the light shield blocks external light, further improving the accuracy of the phone charger casing inspection. Furthermore, as the testing platform moves to feed material, the first receiving block moves synchronously. Under the traction of the receiving rod, the cabinet door flips and closes along the testing cabinet, realizing automatic door closing during the feeding process. This eliminates the need for manual door closing, improving the efficiency of feeding and discharging. Furthermore, as the testing platform moves into the testing cabinet, it drives the auxiliary gear to contact the third rack, causing the auxiliary gear to rotate. Under the action of the spring pawl, the reciprocating screw rotates, thereby driving the screw sleeve to move back and forth along the limit plate. This allows the electrostatic dust removal brush to clean the floating dust on the outer wall of the mobile phone charger casing, preventing the floating dust from adhering and refracting the detection light, reducing the false judgment rate during testing, and further improving the accuracy of testing the mobile phone charger casing. The device is equipped with a testing platform, a cleaning mechanism, a first gear, a drive motor, a second rotating shaft, and a second gear. When the testing platform is fed, it will drive the first gear and the second gear to mesh. At this time, the drive motor is started, which will cause the second gear, which is fixedly connected to one end of the second rotating shaft, to rotate. This will cause the first gear to rotate, thereby driving the reciprocating screw to rotate. This will cause the transmission disc to idle inside the auxiliary gear. With the cooperation of the first chuck and the second chuck, the clamped mobile phone charger shell can also be flipped over, realizing the flipping and re-cleaning operation during testing, further improving the accuracy and efficiency of testing mobile phone charger shells.

A guide rail 36 is fixedly connected to the outer wall of the first rack 35. A second rack 37 is movably connected to the outer wall of the transmission gear 34. An inspection table 38 is fixedly connected to the top of the second rack 37. A T-shaped block 39 is fixedly connected to the bottom. A supplementary light 11 is installed inside the testing cabinet 1. A main telescopic rod 12 is installed inside the testing cabinet 1. A diffuse reflector 13 is hinged to the output end of the main telescopic rod 12. An auxiliary telescopic rod 14 is hinged to the outer wall of the main telescopic rod 12. The output end of the auxiliary telescopic rod 14 is hinged to the diffuse reflector 13 for angle adjustment. A sleeve 32 and a first rotating rod 33 form a rotating structure. A transmission gear 34 forms a rotating structure with the sleeve 32 via the first rotating rod 33. The transmission gear 34 is symmetrically arranged about the central axis of the first rotating rod 33. The transmission gear 34 meshes with a first rack 35. 4 engages with the second rack 37. The guide rail 36 is fixedly installed on the inner wall of the testing cabinet 1. The guide rail 36 has a slotted design. The T-shaped block 39 and the guide rail 36 form a sliding structure. The outer wall of the testing table 38 is fixedly connected to the first receiving block 381. The inner wall of the first receiving block 381 is movably connected to the receiving rod 382. The outer wall of the receiving rod 382 is movably connected to the second receiving block 383. The outer wall of the second receiving block 383 is movably connected to the cabinet door 384. The cabinet door 384 has a T-shaped sliding groove 385 inside. The outer wall of the cabinet door 384 is movably installed with the second rotating rod 386. The first receiving block 381 and the receiving rod 382 are hinged together. The receiving rod 382 and the... The second receiving block 383 is hinged and forms a sliding structure with the cabinet door 384 through the T-shaped slide groove 385. The cabinet door 384 forms a rotating structure with the testing cabinet 1 through the second rotating rod 386. A guide plate 3811 is fixedly connected to the outer wall of the first receiving block 381. A guide groove 3812 is opened inside the guide plate 3811. A guide rod 3813 is movably connected inside the guide groove 3812. A light shield 3814 is fixedly connected to one end of the guide rod 3813. The guide plate 3811 forms a sliding structure with the guide rod 3813 through the guide groove 3812. The guide rod 3813 is symmetrically arranged about the central axis of the light shield 3814.

[0020] By activating the electric push rod 31, the sleeve 32 moves, causing the transmission gear 34, which is fixedly connected to the end of the first rotating rod 33, to move along the first rack 35. Since the transmission gear 34 meshes with the first rack 35, it rotates during movement. Because the transmission gear 34 meshes with the second rack 37, it moves the second rack 37 along the transmission gear 34, and the stroke of the second rack 37 is twice that of the transmission gear 34. This moves the inspection table 38 into the inspection cabinet 1. At this time, the T-shaped block 39 slides along the groove on one side of the guide rail 36, allowing the mobile phone charger casing installed on the inspection table 38 to be fed quickly. Conversely, when the transmission gear 34 moves to the end position of the first rack 35, it moves the inspection table 38 out of the inspection cabinet 1, facilitating material removal after defect detection. As the inspection table 38 moves and feeds material, it causes the first receiving block 381 to move synchronously. Under the traction of the receiving rod 382, ​​the second receiving block 383 slides along the T-shaped groove 385. Under the action of the second rotating rod 386, the cabinet door 384 is driven to flip and close along the inspection cabinet 1. During the movement of the first receiving block 381, the guide plate 3811 is driven to move, so that the guide rod 3813 slides along the guide groove 3812. When the guide rod 3813 moves to the turning point of the guide groove 3812, it drives the guide rod 3813 to slide down along the guide groove 3812, so that the light shield 3814 is pulled down. Finally, when the inspection table 38 is fully fed, the light shield 3814 covers the outside of the mobile phone charger shell being inspected, which can block the outside light. At this time, the supplementary light 11 is turned on, so that the light hits the diffuse reflection plate 13. With the cooperation of the main telescopic rod 12 and the auxiliary telescopic rod 14, the angle of the diffuse reflection plate 13 can be adjusted so that the light is reflected by the diffuse reflection plate 13 onto the surface of the mobile phone charger shell. At this time, the appearance defects of the mobile phone charger shell can be collected and analyzed by the image acquisition camera 2, thereby realizing the appearance inspection of the mobile phone charger shell.

[0021] Reference Figure 3 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, a cleaning mechanism 4 is fixedly connected to the top of the testing table 38. The cleaning mechanism 4 includes a U-shaped support frame 41 fixedly installed on the top of the testing table 38. A limit plate 42 is fixedly connected to the inner wall of the U-shaped support frame 41. A reciprocating screw 43 is movably connected inside the U-shaped support frame 41. A transmission disk 44 is fixedly connected to one end of the reciprocating screw 43. A spring pawl 441 is movably connected to the outer wall of the transmission disk 44. An auxiliary gear 442 is movably connected to the outer wall of the transmission disk 44. A ratchet groove 443 is opened inside the auxiliary gear 442. A third rack 45 is movably connected to the outer wall of the auxiliary gear 442. An L-shaped bracket 46 is fixedly connected to the outer wall of the third rack 45. The top of the L-shaped bracket 46 is fixedly installed on the inner wall of the testing cabinet 1. A threaded sleeve 47 is movably connected to the outer wall of the reciprocating screw 43. A receiving plate 48 is fixedly connected to the outer wall of the threaded sleeve 47. An electrostatic dust removal brush 49 is fixedly connected to the outer wall of 48. A first chuck 431 is fixedly connected to the outer wall of the reciprocating screw 43. A movable column 432 is fixedly connected to the outer wall of the first chuck 431. A second chuck 433 is movably connected to the outer wall of the movable column 432. A clearance groove 434 is provided inside the second chuck 433. A first rotating shaft 435 is fixedly connected to the inner wall of the second chuck 433. An assembly block 436 is fixedly connected to one end of the first rotating shaft 435. An auxiliary gear 442 is meshed with a third rack 45. The auxiliary gear 442 forms a rotating structure with the U-shaped support frame 41 through the reciprocating screw 43. A threaded sleeve 47 forms a sliding structure with the limiting plate 42 through the reciprocating screw 43. The movable column 432 is movably connected to the second chuck 433 through the clearance groove 434. The assembly block 436 forms a rotating structure with the U-shaped support frame 41 through the first rotating shaft 435.

[0022] As the testing platform 38 moves into the testing cabinet 1, during the feeding process, it drives the auxiliary gear 442 to contact the third rack 45. Because the auxiliary gear 442 and the third rack 45 are meshed, the auxiliary gear 442 rotates. Under the action of the spring pawl 441, it drives the internal transmission disc 44 to rotate, causing the reciprocating screw 43 to rotate. This, in turn, drives the threaded sleeve 47 to reciprocate along the limit plate 42, allowing the electrostatic dust removal brush 49 to clean the dust on the outer wall of the mobile phone charger casing. Furthermore, the rotation of the reciprocating screw 43 drives the first chuck 4... 31. When the movable column 432 moves into the clearance groove 434, it will drive the second chuck 433 to rotate. When the movable column 432 moves out, the second chuck 433 rotates exactly 90°, so that the assembly block 436 fixedly connected to the outer wall of the first rotating shaft 435 rotates 90°. This allows the mobile phone charger shell to rotate on all four sides during the feeding process, and the reciprocating electrostatic dust removal brush 49 will clean the four sides. When the assembly block 436 rotates, the electrostatic dust removal brush 49 moves to the positions on both sides of the mobile phone charger shell without interference.

[0023] Reference Figure 3 , Figure 8 , Figure 10 , Figure 11 and Figure 13 As shown, the other end of the reciprocating screw 43 is fixedly connected to the first gear 5.

The output shaft of the drive motor 7 is fixedly connected to the second rotating shaft 8 through the coupling. One end of the second rotating shaft 8 is fixedly connected to the second gear 9. The U-shaped receiving frame 41 is equipped with a limit component 10. The limit component 10 includes a spring rod and a positioning block, which are used to disassemble and install the mobile phone charger shell. The second gear 9 forms a rotating structure with the fixing plate 6 through the second rotating shaft 8. The second gear 9 is meshed with the first gear 5.

[0024] When the inspection table 38 feeds material, it will drive the first gear 5 to mesh with the second gear 9. At this time, the drive motor 7 is started, which will cause the second gear 9, which is fixedly connected to one end of the second rotating shaft 8, to rotate, causing the first gear 5 to rotate, thereby driving the reciprocating screw 43 to rotate. At this time, the direction of rotation of the transmission disk 44 is the same as the direction of the ratchet groove 443. Under the action of the spring pawl 441, the transmission disk 44 rotates freely in the auxiliary gear 442, that is, the auxiliary gear 442 remains stationary. With the cooperation of the first chuck 431 and the second chuck 433, the clamped mobile phone charger shell can also be flipped over, realizing the flipping and re-cleaning operation during inspection.
