Modes for Carrying Out the Invention

[0015] Please refer to FIG. 1 to FIG. 8 , which illustrate a battery appearance inspection device 100 according to an embodiment of the present application, including a frame 10 , a lighting mechanism 20 , an imaging mechanism 30 , and a rotation drive mechanism 40 .

[0016] 1 to 3 , the frame 10 serves as an installation base; the lighting mechanism 20 includes a first adjustment structure 21 and a light source 22. The first adjustment structure 21 is mounted on the frame 10 and connected to the light source 22 for adjusting the orientation and / or height of the light source 22 relative to the battery 200. The imaging mechanism 30 includes a second adjustment structure 31 and a camera 32. The second adjustment structure 31 is mounted on the frame 10 and connected to the camera 32 for adjusting the orientation and / or height of the camera 32 relative to the battery 200. The rotation drive mechanism 40 is used to clamp the battery 200 and drive the battery 200 to rotate.

[0017] The above-mentioned battery appearance inspection device 100 is connected to the light source 22 through the first adjustment structure 21, so that the direction and / or height of the light source 22 can be adjusted through the first adjustment structure 21, thereby providing illumination to different areas of the battery 200; the camera 32 is connected through the second adjustment structure 31, so that the direction and / or height of the camera 32 can be adjusted, thereby imaging different areas of the battery 200, and a rotation drive mechanism 40 is set to drive the battery 200 to rotate, so that the entire circumferential surface of the battery 200 can be illuminated by the light source 22 and photographed by the camera 32 for inspection, thereby improving the accuracy of the appearance inspection of the battery 200.

[0018] Specifically, the battery 200 in this embodiment is described by taking a cylindrical battery as an example.

[0019] Wherein, please refer to Figures 1, 4 and 5. The cylindrical battery 200 is transported by the conveyor chain. When the cylindrical battery 200 reaches the predetermined position, the entire rotating drive mechanism 40 moves upward to lift the cylindrical battery 200 on the conveyor chain. The battery appearance inspection device 100 of this embodiment also includes a lifting drive mechanism 50. The lifting drive mechanism 50 is connected to the rotating drive mechanism 40 and is used to drive the rotating drive mechanism 40 to rise or fall. In this way, the lifting drive mechanism 50 drives the rotating drive mechanism 40 to rise and fall, thereby realizing the support detection of the battery and the separation after the detection is completed, so that the cylindrical battery 200 can continue to be transported away by the conveyor chain after the detection is completed.

[0020] Specifically, the lifting drive mechanism 50 in this embodiment includes a support frame 51 and a second linear module 52 arranged on the support frame 51. The second linear module 52 is arranged in the vertical direction and connected to the rotation drive mechanism 40, thereby driving the rotation drive mechanism 40 to perform lifting and lowering movements.

[0021] Referring to Figures 4 and 5, the rotation drive mechanism 40 of this embodiment includes a driving member 41, a transmission assembly 42 and a rotating sleeve 43. The transmission assembly 42 is transmission-connected between the driving member 41 and the rotating sleeve 43. The rotating sleeve 43 is configured to clamp the cylindrical battery 200 in pairs so as to drive the cylindrical battery 200 to rotate under the drive of the driving member 41. In this way, under the drive of the driving member 41, power is transmitted to the rotating sleeve 43, and the cylindrical battery 200 is supported by the rotating sleeve 43. At the same time, the rotation of the rotating sleeve 43 can also synchronously drive the cylindrical battery 200 to rotate.

[0022] The driving member 41 of this embodiment is a driving motor.

[0023] Specifically, the transmission assembly 42 includes a driving gear 421, a conveyor belt 422 and a transmission gear 423. The driving gear 421 is connected to the driving member 41, and the conveyor belt 422 is respectively connected to the driving gear 421 and the transmission gear 423. The transmission gear 423 and the rotating sleeve 43 are coaxially arranged in a one-to-one correspondence. Therefore, under the rotation of the driving motor, the driving gear 421 is driven to rotate, and the driving gear 421 drives the conveyor belt 422 to rotate. The rotation of the conveyor belt 422 drives the transmission gear 423 to rotate. Since the transmission gear 423 is coaxially arranged with the rotating sleeve 43, it can drive the rotating sleeve 43 to rotate, so that the rotation of the rotating sleeve 43 drives the rotation of the cylindrical battery 200, so that the camera 32 can image different surface areas of the cylindrical battery 200.

[0024] In order to ensure the support stability of the cylindrical battery 200, the transmission assembly 42 includes two driving gears 421, two conveyor belts 422 and two groups of transmission gear groups. A driving gear 421, a conveyor belt 422 and a group of transmission gear groups correspond to the transmission setting, and each group of transmission gear groups includes at least one pair of transmission gears 423; the rotation drive mechanism 40 includes two groups of rotating sleeve groups, and one group of rotating sleeve groups, a group of transmission gear groups and a conveyor belt 422 correspond to the transmission setting, and each group of rotating sleeve groups includes at least one pair of rotating sleeves 43, wherein each pair of rotating sleeves 43 is used to clamp a In this way, by setting two relatively arranged groups of rotating sleeve groups, one cylindrical battery 200 is supported by two relatively arranged pairs of rotating sleeves 43, thereby achieving stable support for the cylindrical battery 200; at the same time, the method of supporting one cylindrical battery 200 by two pairs of rotating sleeves 43 is relatively different from the method of using each rotating sleeve 43 with a longer length. Since the surface of the rotating sleeve 43 needs to be covered with a glue structure that protects the cylindrical battery 200, the supporting method of the rotating sleeve 43 with a shorter length in this embodiment reduces the production cost of the rotating sleeve 43.

[0025] It can be understood that since a conveyor belt 422 needs to transmit the rotating sleeve 43 in each group, in order to ensure the tension of each conveyor belt 422, the transmission assembly 42 can also include two tensioning wheels 44, one tensioning wheel 44 is used to tension a conveyor belt 422 to ensure the tension of each conveyor belt 422 and realize stable transmission of the rotating sleeve 43.

[0026] Please refer to Figures 6 to 8. In one embodiment of the present application, when adjusting the light source 22, the first adjustment structure 21 includes a first adjustment frame 211, a first sliding column 212 and a first mounting frame 213. The first mounting frame 213 is connected to the light source 22. The first adjustment frame 211 is provided with a first arc groove 2111. The first sliding column 212 is connected to the first mounting frame 213 and is slidably arranged with the first arc groove 2111 to adjust the illumination angle of the light source 22. In this way, when the illumination angle of the light source 22 needs to be adjusted, the illumination angle of the light source 22 is achieved by sliding the first sliding column 212 in the first arc groove 2111 and sliding to different positions of the first arc groove 2111.

[0027] Specifically, the first mounting frame 213 includes a first plate 2131 and a second plate 2132, which are separated and arranged on opposite sides of the first adjustment frame 211. The second plate 2132 is used to be mounted on the light source 22. The locking screw 215 connects the first plate 2131 and the second plate 2132 and is disposed through the first arcuate groove 2111 and can slide within the first arcuate groove 2111. The first sliding post 212 is a pin that also slides within the first arcuate groove 2111. Thus, by providing the pin to slide within the first arcuate groove 2111, the locking screw 215 can slide together, and the pin can slide against the groove wall of the first arcuate groove 2111, thereby improving the accuracy of the sliding adjustment of the light source 22 within the first arcuate groove 2111.

[0028] Please refer to Figures 7 and 8. The first adjustment structure 21 also includes an adjusting screw 214. The adjusting screw 214 is connected between the first mounting bracket 213 and the light source 22 and is used to adjust the height of the light source 22. The height of the light source 22 can be adjusted by turning the bolt to lower or raise the light source 22, thereby achieving adjustment of the height position of the light source 22.

[0029] Please refer to Figures 6 and 8. In one embodiment of the present application, when adjusting the angle of the camera 32, the second adjustment structure 31 includes a second adjustment frame 311, a second sliding column (not shown in the figure) and a second mounting frame 313. The second mounting frame 313 is connected to the camera 32. The second adjustment frame 311 is provided with a second arc groove 3111. The second sliding column is connected to the second mounting frame 313 and is slidably arranged with the second arc groove 3111 to adjust the illumination angle of the light source 22. In this way, when adjusting the camera 32, the second sliding column slides along the second arc groove 3111, thereby realizing the adjustment of the camera 32 to different positions on the second adjustment frame 311, thereby realizing the adjustment of the illumination angle of the camera 32.

[0030] Specifically, similar to the installation method of the light source 22, the second mounting bracket 313 of this embodiment includes a third plate 3131 and a fourth plate 3132, which are separated and arranged on opposite sides of the second adjustment bracket 311. The fourth plate 3132 is used to connect to the camera 32. The locking screw connects the third plate 3131 and the fourth plate 3132 and is inserted into the second arcuate groove 3111 and can slide within the second arcuate groove 3111. The second sliding post is a pin that also slides within the second arcuate groove 3111. Thus, by providing the pin to slide within the second arcuate groove 3111, the locking screw can slide against the groove wall of the second arcuate groove 3111, thereby improving the accuracy of the sliding adjustment of the light source 22 within the second arcuate groove 3111.

[0031] In order to facilitate the adjustment of the height position of the camera 32, the second adjustment structure 31 also includes a linear slide 314, which is connected between the camera 32 and the second mounting bracket 313, and is used to adjust the height of the camera 32. When the height position of the camera 32 needs to be adjusted, the bolt in the linear slide 314 is turned to drive the camera 32 to rotate along the gear rod, thereby adjusting the height position of the camera 32.

[0032] In addition, in order to achieve precise adjustment of the imaging angle of the camera 32, the second adjustment structure 31 also includes an arc slide 315, which is connected between the linear slide 314 and the second mounting bracket 313, specifically, between the linear slide 314 and the fourth plate 3132, and is used to adjust the illumination angle of the camera 32 in the front and rear directions and / or the illumination angle in the left and right directions. In this way, the second slide column slides in the second arc groove 3111 to achieve preliminary adjustment of the angle of the camera 32. After the preliminary adjustment is completed, the camera 32 is finely adjusted by screwing different bolts in the arc slide 315 to ensure the accurate orientation of the camera 32.

[0033] Specifically, the arc-shaped slide 315 of this embodiment includes two adjustment parts 3151, one adjustment part 3151 is used to adjust the camera 32 to swing in the front and back directions, and the other adjustment part 3151 is used to adjust the camera 32 to swing in the left and right directions, thereby achieving the effect of precise adjustment of the orientation angle of the camera 32 through the cooperation of the two adjustment parts 3151.

[0034] Please refer to Figures 1 to 3. In one embodiment of the present application, since the rotation drive mechanism 40 can support multiple cylindrical batteries 200, corresponding to the placement positions of the multiple cylindrical batteries on the rotation drive mechanism 40, the battery appearance inspection device 100 also includes a first linear module 60. The first linear module 60 is connected to the frame 10 and is used to drive the lighting mechanism 20 and the imaging mechanism 30 to perform linear motion in the horizontal direction. Therefore, after completing the scan of a cylindrical battery 200, the lighting mechanism 20 and the imaging mechanism 30 are driven by the first linear module 60 to perform linear motion in the horizontal direction so that they can approach different batteries.

[0035] The usage process of the above-mentioned battery appearance inspection device 100 is as follows: according to the different sizes of the cylindrical batteries 200, the light source 22 is slid along the first arc groove 2111 to adjust the illumination angle of the light source 22, and the adjustment screw 214 is turned to adjust the placement height of the light source 22; the camera 32 is slid along the second arc groove 3111 to achieve preliminary adjustment of the illumination angle of the camera 32, and the linear slide 314 is used to adjust the placement height of the camera 32, and the arc slide 315 is used to achieve precise adjustment of the illumination angle of the camera 32. After completing the adjustment of the light source 22 and the camera 32, the cylindrical battery 200 can be loaded through the conveyor chain, so that the cylindrical battery 200 can be lifted and rotated by the lifting drive structure and the rotation drive mechanism 40 respectively.
