[0039] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1 - Figure 13 As shown, an automatic inspection machine for battery cell carrier boxes includes an inspection box 1. From left to right, a feeding component 2, a lifting component 3, a traversing component 4, and an unloading component 6 are arranged sequentially in the middle of the inspection box 1. Two sets of lifting components 3 are symmetrically arranged on the left and right sides. The traversing component 4 is located between the two sets of lifting components 3. Inspection components 5 are arranged at both ends of the traversing component 4. A barcode scanner 101 and a card reader 102 are installed on the inner top wall of the inspection box 1, both positioned above the left lifting component 3. After the carrier box is moved above the left lifting component 3, the card reader 102 reads the carrier box information using an RFID reading head, while the barcode scanner 101 takes a picture and reads the carrier box code, comparing it with the chip information for verification. If the information matches, the machine is considered correct; otherwise, the information captured by the camera is used. The chip information is rewritten using the box code as a reference. If the chip information cannot be read, it is determined that the chip is damaged. The computer records the damaged number for easy subsequent repair. The inside of the testing box 1 is equipped with a deformation detection camera 103. There are two deformation detection cameras 103 symmetrically arranged front and back. Both deformation detection cameras 103 are located on the left side of the horizontal moving part 4 and on the front and back sides of the left lifting part 3, respectively. When the horizontal moving part 4 moves the two carrier boxes to the testing parts 5 on the front and back sides, the two carrier boxes will pass through the deformation detection cameras 103 on the front and back sides, so that the deformation detection cameras 103 can detect whether the carrier box is deformed and then determine whether the carrier box is a qualified product. The carrier box is a U-shaped box with open sides, so that the testing part 5 can smoothly test the inner wall of the carrier box.

[0041] The lifting component 3 includes a mounting frame 31 and a lifting placement seat 32, with two mounting frames 31 and two lifting placement seats 32 arranged symmetrically front and rear. The mounting frame 31 is located inside the detection box 1. A drive motor 311 is installed inside the upper end of the mounting frame 31. The output end of the drive motor 311 is connected to a worm gear 312. A worm wheel 313 is meshed with the side wall of the worm gear 312. A threaded rod 314 is installed in the middle of the worm wheel 313. Both the upper and lower ends of the threaded rod 314 are rotatably installed inside the mounting frame 31. A lifting connecting block 315 is threadedly connected to the circumferential surface of the threaded rod 314. A lifting groove is opened inside the mounting frame 31, and the lifting connecting block 315 is located inside the lifting groove. This allows the lifting connecting block 315 to move vertically smoothly. The lifting placement seat 32 includes a lifting support plate 321. One side of the lifting support plate 321 is fixedly connected to the lifting connecting block 315. A speed-regulating motor 322 is provided on the inner bottom wall of the lifting support plate 321. The power output end of the speed-regulating motor 322 is connected to a synchronous belt 323 through a toothed chain mechanism. The synchronous belt 323 is connected to a pulley shaft through a pulley, and the pulley shaft is rotatably mounted on the lifting support plate 321. The toothed chain is driven by two sprockets, which are respectively located at the power output ends of the pulley shaft and the speed-regulating motor 322. This allows the speed-regulating motor 322 to smoothly drive the synchronous belt 323 to rotate when it is working.

[0042] It should be noted that the internal structure of the feeding component 2 and the discharging component 6 is roughly the same as that of the lifting and placing seat 32. Both are equipped with a speed-regulating motor 322. The speed-regulating motor 322 is connected to two synchronous belts 323 through a toothed chain mechanism, so that the carrier box can be smoothly transported from the left side of the feeding component 2 to the right side. After passing through the left lifting component 3, the transverse component 4 and the right lifting component 3, it is moved out of the detection box 1 through the discharging component 6.

[0043] The transverse moving component 4 includes a second mounting bracket 41 and a detection placement seat 42. Two detection placement seats 42 are symmetrically arranged front and rear, allowing two carrier boxes to be simultaneously moved to the front and rear sets of detection components 5 for detection, thus improving detection efficiency. The second mounting bracket 41 is located inside the detection box 1, and a second drive motor 411 is installed inside the mounting bracket 41. The power output end of the second drive motor 411 is connected to a second threaded rod 412. A third threaded rod 413 is located at the front end of the second threaded rod 412. Both the second threaded rod 412 and the third threaded rod 413 have horizontal moving blocks 414 threadedly connected to their circumferential surfaces. The detection placement seat 42 includes a mounting plate 421. The lower surface of the mounting plate 421 is fixedly connected to the upper surface of the horizontal moving blocks 414. A speed-regulating motor 422 is provided on the side of the mounting plate 421 away from the feeding component 2. The power output end of the speed-regulating motor 422 is connected to a synchronous belt 423 via a toothed chain mechanism. The synchronous belt 423 is rotatably mounted on the mounting plate 421 via a pulley and a pulley shaft. Shaft 2 is connected to the power output end of speed-regulating motor 422 via a sprocket and a toothed chain. A lifting cylinder 424 is located in the middle of the upper surface of mounting plate 421. A lifting support plate 425 is located above the lifting cylinder 424. A servo motor 426 is located on the upper surface of the lifting support plate 425. The power output end of the servo motor 426 is connected to a rotating shaft 427 via a toothed chain mechanism. The lower end of the rotating shaft 427 is rotatably mounted in the middle of the lifting support plate 425. A rotary plate 428 is located at the upper end of the rotating shaft 427. Furthermore, the side wall of the rotary plate 428 does not contact the upper inner side wall of the mounting plate 421. At the same time, the rotary plate 428 is positioned between the two synchronous belts 423. When the rotary plate 428 needs to drive the carrier box above it to rotate, the lifting cylinder 424 first drives the lifting support plate 425 and the rotary plate 428 to move upward a certain distance, so that the rotary plate 428 moves above the synchronous belt 423. At this time, the lower end of the carrier box does not contact the surface of the synchronous belt 423. Then the rotary plate 428 can stably drive the carrier box to rotate.

[0044] It should be noted that the threads on the surfaces of threaded rod 2 412 and threaded rod 3 413 have opposite directions of rotation. When threaded rod 2 412 and threaded rod 3 413 rotate synchronously, the two horizontal moving blocks 414 on their surfaces will move closer or further away from each other, thereby driving the two sets of detection placement seats 42 to move closer or further away from each other. When the detection placement seats 42 move closer and closer to the middle of the mounting frame 2 41, the two sets of detection placement seats 42 are exactly located on the right side of the two sets of lifting placement seats 32 on the left, so that the carrier box on the lifting placement seat 32 can be stably transferred to the detection placement seat 42.

[0045] The detection component 5 includes a camera lifting mechanism 51 and a backlight moving mechanism 52. The camera lifting mechanism 51 is located on the right side of the horizontal moving component 4, and the backlight moving mechanism 52 is located on the left side of the horizontal moving component 4. The camera lifting mechanism 51 includes a second lifting device 511, which is located inside the detection box 1. The internal structure of the second lifting device 511 is the same as that of the mounting bracket 31. A lifting connecting plate 512 is movably connected to the lower left side of the second lifting device 511. Defect and crack detection cameras 513 are provided on the upper surfaces of both the front and rear sides of the lifting connecting plate 512. The two defect and crack detection cameras 513 can simultaneously detect the front and rear inner walls of the carrier box, improving detection efficiency. A background light source 514 is provided on the left side of each of the two defect and crack detection cameras 513. The backlight moving mechanism 52 includes a fixing plate 521, and two fixing plates 521 are symmetrically arranged front and rear. Both fixing plates 521 are located in the detection box. Inside 1, telescopic cylinders 522 are provided on the surfaces of the two fixed plates 521. Backlight mounting plates 523 are provided on the right ends of the two telescopic cylinders 522. Sliding limit plates 524 are provided on the upper and lower ends of the outer side of the backlight mounting plates 523. Sliding grooves matching the sliding limit plates 524 are provided on the upper and lower ends of the fixed plates 521. The setting of the sliding limit plates 524 and the sliding grooves provides support for the backlight mounting plates 523, improves the stability of the backlight mounting plates 523, and does not affect the horizontal movement of the backlight mounting plates 523. Background light source II 525 is provided on the inner side of the two backlight mounting plates 523. The two background light sources II 525 are respectively set on the front and rear sides of the detection placement seat 42. The setting of background light source I 514 and background light source II 525 provides light source for the defect and crack detection camera 513, so that the defect and crack detection camera 513 can clearly capture the internal condition of the carrier box and improve the detection quality.

[0046] It should be noted that before the transverse component 4 moves the carrier box to the detection component 5, the backlight mounting plate 523 is in a retracted state, that is, the backlight mounting plate 523 overlaps with the fixed plate 521. The state 11 in the figure is the state after the telescopic cylinder 522 drives the backlight mounting plate 523 to move to the right when the detection placement seat 42 moves the carrier box to the middle of the camera lifting mechanism 51 and the backlight moving mechanism 52.

[0047] Both the feeding component 2 and the discharging component 6 are provided with upper and lower layers, and each layer has two conveying stations symmetrically arranged front and back. The two-layer arrangement of the feeding component 2 can realize the upper and lower layer conveying of carrier boxes, and each layer can convey two carrier boxes at the same time. The upper layer discharging component 6 is the outlet for qualified products, and the lower layer discharging component 6 is the outlet for defective products. The upper layer feeding component 2, the discharging component 6, the lifting placement seat 32 and the detection placement seat 42 are all on the same horizontal plane, so that the carrier box can stably transition between the feeding component 2 and the left lifting placement seat 32, between the lifting placement seat 32 and the detection placement seat 42, between the detection placement seat 42 and the right lifting placement seat 32, and between the right lifting placement seat 32 and the discharging component 6.

[0048] In use, the present invention places two carrier boxes to be tested on the feeding component 2. When the two carrier boxes are placed on the upper feeding component 2, the feeding component 2 can smoothly transfer the carrier boxes to the two lifting placement seats 32 on the left. When the two carrier boxes are placed on the lower feeding component 2, the drive motor 311 drives the worm 312, worm wheel 313 and threaded rod 314 to rotate, so that the lifting connecting block 315 drives the lifting placement seat 32 to move vertically downward until it is flush with the lower feeding component 2. Only then can the feeding component 2 transfer the carrier boxes to the lifting placement seat 32. Then the drive motor 311 rotates in the opposite direction, so that the lifting placement seat 32 drives the carrier boxes to return to the upper position.

[0049] After the carrier box is transferred to the lifting placement seat 32, the barcode camera 101 and the card reader 102 work to read the carrier box information and code, and compare and verify it with the chip information. If the information matches, it is judged to be correct. If it does not match, the chip information is rewritten with reference to the carrier box code captured by the camera. If the chip information cannot be read, it is judged to be damaged and the computer records the damaged number.

[0050] Next, drive motor 2 411 drives threaded rod 2 412 and threaded rod 3 413 to rotate, causing the two horizontal moving blocks 414 to move the two sets of detection placement seats 42 closer to each other and move to the right side of the two lifting placement seats 32 on the left. At this time, the speed regulating motor 1 322 inside the lifting placement seat 32 and the speed regulating motor 2 422 inside the detection placement seat 42 work, so that the carrier box is smoothly moved to the middle of the upper surface of the detection placement seat 42. Then drive motor 2 411 rotates in the opposite direction, driving the two detection placement seats 42 to move to the front and rear two sets of detection components 5 respectively. During the movement, the detection placement seat 42 will carry the carrier box past the deformation detection camera 103. The deformation detection camera 103 will detect whether the carrier box is deformed, and then transmit the detected data to the computer for recording.

[0051] After the inspection placement seat 42 moves the carrier box to the middle of the camera lifting mechanism 51 and the backlight moving mechanism 52, the telescopic cylinder 522 works to move the backlight mounting plate 523 and the second background light source 525 to the right, so that the two second background light sources 525 move to the front and rear sides of the carrier box respectively, providing light sources for the vicinity of the carrier box. Then the lifting device 511 and the defect and crack detection camera 513 work. The lifting device 511 drives the defect and crack detection camera 513 to move vertically, and the defect and crack detection camera 513 can detect whether there are cracks or defects inside the carrier box from bottom to top. The data after detection is transmitted to the computer.

[0052] After the inspection is completed, the telescopic cylinder 522 first moves the backlight mounting plate 523 to the right, so that the backlight mounting plate 523 moves to the left side of the carrier box. Then, the drive motor 411 works to move the inspection placement seat 42 and the carrier box to the left side of the right lifting placement seat 32 in the middle. Then, the carrier box is transferred to the right lifting placement seat 32 by the synchronous belt 423 and the synchronous belt 323 inside the right lifting placement seat 32. Then, according to the result judged by the computer, when the carrier box is qualified, the synchronous belt 323 continues to rotate, and at the same time, the upper discharge part 6 works to move the carrier box out of the inspection box 1 from the upper discharge part 6. When the carrier box is defective, the right drive motor 311 works to move the right lifting placement seat 32 and the defective carrier box down to the left side of the lower discharge part 6. Then, the synchronous belt 323 inside the lifting placement seat 32 and the lower discharge part 6 work to move the defective carrier box out of the inspection box 1 from the lower discharge part 6.
