[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific embodiments.

[0029] As Figure 1 shown, an embodiment provides a sorting device, including a first driving member 51, a driving wheel 52, a driven wheel 54 and a transmission belt 55; the driving wheel 52 is fixed to the power output end of the first driving member 51, the transmission belt 55 is sleeved outside the driving wheel 52 and the driven wheel 54, and at least one partition plate 53 is connected to the outside of the transmission belt 55.

[0030] The first driving member 51 drives the driving wheel 52 to rotate, the driving wheel 52 then drives the transmission belt 55 to rotate, and the partition plate 53 on the transmission belt 55 then rotates accordingly. The partition plate 53 extends to the detection device, and the sorting device 5 is controlled by a computer program. When an unqualified cylindrical battery case 6 is detected, when the unqualified battery case 6 moves to the sorting device 5, the first driving member 51 is started, and the partition plate 53 knocks the battery case 6 off the detection device to achieve the sorting of the battery case 6. If the current object to be sorted does not need to be sorted at this station, the transmission belt 55 does not move.

[0031] Furthermore, a plurality of partitions 53 are evenly connected to the transmission belt 55, and the distance between adjacent partitions 53 is greater than the length of a single object to be tested and less than the sum of the lengths of two objects to be tested. The sorting device 5 is controlled by a computer program. If the battery shell 6 needs to be sorted out, the first driving member 51 is controlled to move, and the transmission belt 55 moves a spacing with the partition 53 to realize the sorting and pushing out of the battery shell 6. The transmission belt 55 moves the spacing of a partition 53, which can not only push out the battery shell 6, but also prevent the partition 53 from blocking the normal moving and transportation route of the battery shell 6. At the same time, according to the actual detection needs, multiple sorting devices 5 can be set on the detection equipment to achieve different sorting requirements. Setting multiple sorting devices 5 and setting different output directions can realize graded sorting, sort out battery shells 6 with different defect levels, and realize graded sorting.

[0032] like Figure 2 As shown, the present invention also provides a cylindrical battery shell appearance inspection device, including a feeding mechanism 1, a transfer mechanism, a detection section and a sorting device 5, the feeding mechanism 1 is arranged at the input end of the transfer mechanism, and the sorting device 5 is arranged above the transfer mechanism; the detection section includes an end face detection section and an outer cylindrical surface detection section, the end face detection section is arranged on the side of the transfer mechanism, and the outer cylindrical surface detection section is arranged above the transfer mechanism.

[0033] The loading mechanism 1 loads the battery shell 6 from the external battery shell 6 barrel, and the loading mechanism 1 transports the battery shell 6 and conveys it to the transfer mechanism. The transfer mechanism conveys the battery shells 6 one by one. During the conveying process, the battery shell 6 will pass through the end face detection section and the outer cylindrical surface detection section, and the outer cylindrical surface and the end face of the battery shell 6 will be inspected respectively. When the corresponding detection section detects that the end face or outer cylindrical surface of the battery shell 6 is defective and unqualified, the unqualified information will be transmitted to the external computer program, and the battery shell 6 will continue to move. When the unqualified battery shell 6 moves to the position of the sorting device 5, the computer program will control the action of the sorting device 5 to push out the unqualified battery shell 6 to achieve sorting. The qualified battery shell 6 continues to move to the next production and processing device for the next process.

[0034] This equipment can complete two inspections with one transfer mechanism, cleverly combines different arrangements of transfer motion pallets, and can complete two inspections with one transfer mechanism, thereby achieving comprehensive inspection of the two end faces and outer cylindrical surface of the cylindrical battery shell 6, and improving the accuracy and efficiency of the inspection.

[0035] Furthermore, if Figures 4-5As shown, the transfer mechanism includes a first transfer section 3 and a second transfer section 4. The first transfer section 3 includes a second driving member 32, a first connecting plate 34, a first support 35, a rotating roller 33, and a first transfer moving support plate 31. The power output end of the second driving member 32 is fixedly connected to one side of the first connecting plate 34. The other side of the first connecting plate 34 is rotatably connected to the first support 35. Two first transfer moving support plates 31 are fixedly arranged side by side at the upper end of the first support 35. A plurality of rotating rollers 33 are arranged in sequence, and the rotating rollers 33 are arranged between the two first transfer moving support plates 31. The second transfer section 4 includes a third driving member 42, a second connecting plate 44, a second support 45, a fixed support plate 43, and a second transfer moving support plate 41. The power output end of the third driving member 42 is fixedly connected to one side of the second connecting plate 44. The other side of the second connecting plate 44 is rotatably connected to the second support 45. The second transfer moving support plate 41 is fixedly arranged at the upper end of the second support 45. Two fixed support plates 43 are arranged side by side, and the second transfer moving support plate 41 is arranged between the two fixed support plates 43.

[0036] The battery case 6 is conveyed from the feeding mechanism 1 to the first transfer section 3, and the battery case 6 falls onto the first transfer moving support plate 31 of the first transfer section 3. Driven by the second driving member 32 through the first connecting plate 34 and the first support 35, the first transfer moving support plate 31 makes a circular motion. When the first transfer moving support plate 31 descends, the battery case 6 is placed on the rotating roller 33, and the rotating roller 33 drives the battery case 6 to rotate by rotation. When the first transfer moving support plate 31 ascends, it drives the battery case 6 to move from one rotating roller 33 to the next rotating roller 33. Through such repeated movements, the battery case 6 is conveyed backward.

[0037] After the battery case 6 passes the outer cylindrical surface inspection on the first transfer section 3, the battery case 6 enters the second transfer section 4. The two fixed support plates 43 are arranged inside the two first transfer moving support plates 31. Moving from the first transfer moving support plate 31 to the fixed support plate 43, the battery case 6 is transferred on the fixed support plate 43 by the second transfer moving support plate 41. Driven by the third driving member 42 through the third connecting plate and the second support 45, the second transfer moving support plate 41 makes a circular motion. When the second transfer moving support plate 41 ascends, it lifts the battery case 6 placed on the fixed support plate 43 and moves it to the placement position of the battery case 6 on the next fixed support plate 43. When the second transfer moving support plate 41 descends, it places the battery case 6 on the placement position of the battery case 6 on the fixed support plate 43 at the next position, realizing the conveyance of the battery case 6.

[0038] Through the above settings of the first transfer section 3 and the second transfer section 4, the battery case 6 is transferred backward one station at a time. The transfer speed can be adjusted by the rotation speeds of the second driving member 32 and the third driving member 42, so that the battery case 6 is detected by the detection section during the transportation process. In the first transfer section 3, the rotating roller 33 drives the battery case 6 to rotate, so that the outer cylindrical surface of the battery case 6 can be detected by the outer cylindrical surface detection section. In the second transfer section 4, the second transfer moving tray 41 moves the battery case 6 as a whole, so that the end face of the battery case 6 can be completely presented in front of the detection end of the end face detection section, so as to clearly and completely detect the situation of the end face of the battery case 6.

[0039] Furthermore, a first bayonet 36 is provided on the first transfer moving tray 31, and a second bayonet 46 is provided on the second transfer moving tray 41. Through the first bayonet 36 and the second bayonet 46, the battery case 6 can be clamped during the transfer process to prevent the battery case 6 from shifting when it is transferred backward.

[0040] Furthermore, the outer cylindrical surface detection section includes a first detection light source 72 and a line array camera 71. Both the first detection light source 72 and the line array camera 71 are arranged above the first transfer moving tray 31. The first detection light source 72 illuminates the outer surface of the battery case 6, providing sufficient brightness for the line array camera 71 to capture the outer cylindrical surface of the battery case 6 and improving the detection accuracy.

[0041] Furthermore, according to the detection requirements, the end face detection section can be provided only on one side of the transfer mechanism to detect only one end face of the battery case 6, or can be provided on both sides of the moving mechanism at the same time to detect the two end faces of the battery case 6 simultaneously. The end face detection section includes a area array camera 81 and a second detection light source 82; the area array camera 81 and the second detection light source 82 are arranged on one side of the fixed tray 43. The second detection light source 82 illuminates the end face of the battery case 6, providing sufficient brightness for the area array camera 81 to capture the end face of the battery case 6 and improving the detection accuracy.

[0042] Further, the end face detection section further includes a slide rail 83, a first slider 84, and a second slider 85. The first slider 84 and the second slider 85 are both slidably connected to the slide rail 83. The second detection light source 82 is fixed to the first slider 84, and the area array camera 81 is fixed to the second slider 85. The second detection light source 82 is arranged in a circular ring shape, and the area array camera 81 is located on the horizontal line where the center of the second detection light source 82 is located. By means of the first slider 84 and the second slider 85, the positions of the area array camera 81 and the second detection light source 82 can be slidably adjusted, realizing flexible adjustment of the distance between the second detection light source 82, the area array camera 81, and the object to be measured. Moreover, no matter how it is adjusted, there will be no tilt or optical center deviation, which is beneficial to the rapid adjustment of the image detection effect and can quickly adjust the detection position to obtain the best detection effect when detecting cylindrical battery cases 6 of different models and specifications.

[0043] Further, as Figure 3 , 6 shown, it further includes an orientation flipping mechanism 2. The orientation flipping mechanism 2 is arranged between the transfer mechanism and the feeding mechanism 1. The orientation flipping mechanism 2 includes a fourth driving member 21, a transmission rod 22, and a rotating seat 24. One end of the transmission rod 22 is fixedly connected to the power output end of the fourth driving member 21, and the other end of the transmission rod 22 is fixedly connected to the rotating seat 24.

[0044] When the battery case 6 comes from the feeding mechanism 1 and first falls onto the rotating seat 24, if the orientation of the battery case 6 is the correct one, the fourth driving member 21 does not act, and the battery case 6 is driven backward by the first transfer moving support plate 31. If the direction of the battery case 6 that falls onto the rotating seat 24 is not the normal detection direction, then the fourth driving member 21 is started. The fourth driving member 21 drives the rotating seat 24 to rotate 180° through the transmission rod 22, so that the battery case 6 on the rotating seat 24 changes its direction, making the mouth or bottom of the battery case 6 face in the same direction. By arranging the orientation flipping mechanism 2 before the cylindrical battery case 6 enters any detection section, the unified orientation of the battery case 6 can simplify the design and implementation of the detection procedure, making the arrangement of devices such as cameras simpler and more accurate, and ensuring that the detection device can operate at a standardized angle. Whether it is visual recognition, dimensional measurement, or other quality inspections, the device can set parameters according to the consistent orientation, reducing the deviations or misjudgments that may occur due to different orientations of the battery case 6, thereby improving the detection speed and accuracy.

[0045] Further, the orientation flipping mechanism 2 further includes a mounting plate 23 and a support seat 25. The transmission rod 22 passes through the mounting plate 23, and the support seat 25 is located on one side of the rotating seat 24 and is mounted on the mounting plate 23. The support seat 25 provides a transfer. After the rotating seat 24 completes the direction adjustment of the battery case 6, the battery case 6 is first transferred to the support seat 25 and then transported backward by the first transfer moving support plate 31.
