The battery exterior vision inspection apparatus 100 according to an embodiment of the application includes a stage 10, an illumination mechanism 20, an imaging mechanism 30, and a rotary drive 40.Reference is made to FIGS. 1 to 3. The cradle 10 serves as a mounting base; the illumination mechanism 20 includes a first adjustment structure 21 and a light source 22, the first adjustment structure 21 being mounted on the cradle 10 and connected to the light source 22 to adjust 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 being mounted on the cradle 10 and connected to the camera 32 to adjust the orientation and / or height of the camera 32 relative to the battery 200; the rotary drive 40 serves to clamp the battery 200 and rotate the battery 200.In the battery exterior vision inspection device 100, by connecting the light source 22 to the first setting structure 21, the orientation and / or height of the light source 22 can be adjusted via the first setting structure 21 to light different areas of the battery 200; by connecting the camera 32 to the second setting structure 31, the orientation and / or height of the camera 32 can be adjusted to image different areas of the battery 200, and the battery 200 is driven to rotate by providing the rotary drive 40, so that the entire circumferential surface of the battery 200 can be irradiated by the light source 22 and photographed by the camera 32 for recognition to improve the accuracy of vision inspection of the battery 200.Specifically, the battery 200 in this embodiment is exemplified with a cylindrical battery.Reference is made to FIGS. 1, 4 and 5. The cylindrical battery 200 is conveyed by a conveyor chain. After the cylindrical battery 200 has arrived at a predetermined position, the entire rotary actuator 40 moves upward to jack the cylindrical battery 200 onto the conveyor chain. The battery exterior vision inspection apparatus 100 of the embodiment further includes a lift drive 50, which lift drive 50 is connected to the rotary drive 40 and is used to drive the rotary drive 40 for raising or lowering, so that the rotary drive 40 is driven by the lift drive 50 for raising and lowering, thus enabling support of the battery for inspection and detachment after completion of inspection, so that the cylindrical battery 200 can be further transported away from the conveyor chain after completion of inspection.Specifically, in the present embodiment, the stroke drive 50 includes a support frame 51 and a second linear module 52 disposed on the support frame 51, and the second linear module 52 is disposed along the vertical direction and connected to the rotary drive 40, thereby driving the rotary drive 40 to perform stroke movement.Reference is made to FIGS. 4 and 5. The rotary drive mechanism 40 of the present embodiment includes a driving member 41, a gear assembly 42, and a rotating sleeve 43, the gear assembly 42 being drivingly connected between the driving member 41 and the rotating sleeve 43, and the rotating sleeve 43 being configured to clamp the cylindrical battery 200 in pairs to drive the cylindrical battery 200 to rotate under the drive of the driving member 41. Under the drive by the drive member 41, the power is transmitted to the rotating sleeve 43, and the rotating sleeve 43 supports the cylindrical battery 200. At the same time, the rotation of the rotating sleeve 43 can also rotate the cylindrical battery 200 synchronously.Here, the driving member 41 of the present embodiment is a driving motor.Specifically, the gear arrangement 42 comprises a drive wheel 421, a conveyor belt 422 and a gear wheel 423, wherein the drive wheel 421 is connected to the drive element 41, the conveyor belt 422 is in gear connection with the drive wheel 421 and the gear wheel 423, the gear wheel 423 is assigned one-to-one to the rotating sleeve 43 and is arranged coaxially thereto, thus the drive wheel 421 is driven to rotate by rotation of the drive motor and the drive wheel 421 drives the conveyor belt 422 to rotate. The rotation of the conveyor belt 422 drives the gear 423 to rotate, and the gear 423 is disposed coaxially with the rotating sleeve 43 so that the rotating sleeve 43 can be driven to rotate, thus the rotation of the cylindrical battery 200 is driven by the rotation of the rotating sleeve 43 and the camera 32 can image various surface areas of the cylindrical battery 200.In order to ensure the support stability for the cylindrical battery 200, the gear arrangement 42 comprises two drive wheels 421, two conveyor belts 422 and two gear sets, wherein one of the drive wheels 421, one of the conveyor belts 422 and one of the gear sets are associated with one another for movement transmission, wherein each of the gear sets comprises at least one pair of gear wheels 423; wherein the rotary drive 40 comprises two rotating sleeve groups and one of the rotating sleeve groups, one of the gear sets and one of the conveyor belts 422 are associated with one another for movement transmission, wherein each of the rotating sleeve groups comprises at least one pair of rotating sleeves 43, wherein each of two opposing pairs of rotating sleeves 43 serves for tensioning one of the cylindrical batteries 200. By providing two sets of rotating sleeve sets arranged in opposition and two pairs of rotating sleeve sets arranged in opposition to support a cylindrical battery, stable support for the cylindrical battery 200 is achieved; at the same time, by the manner of supporting a cylindrical battery 200 by two pairs of rotating sleeves 43, compared to the use of each rotating sleeve 43 having a longer length, since the surface of the rotating sleeve 43 must be covered with a rubber structure protecting the cylindrical battery 200, a reduction in the manufacturing cost of the rotating sleeve 43 is achieved by supporting by the rotating sleeve 43 having a shorter length.Since a conveyor belt 422 needs to drive the rotating sleeve 43 in each group to ensure the tension of each conveyor belt 422, the transmission assembly 42 may naturally also include two tension wheels 44, and one tension wheel 44 is used for tensioning a conveyor belt 422 to ensure the tension of each conveyor belt 422 and realize the stable transmission of movement of the rotating sleeve 43.Reference is made to Figures 6 to 8. In an embodiment of the application, it is arranged that, when adjusting the light source 22, the first adjustment structure 21 includes a first adjustment frame 211, a first slide post 212, and a first mounting bracket 213, the first mounting bracket 213 being connected to the light source 22, the first adjustment frame 211 being provided with a first arc groove 2111, the first slide post 212 being connected to the first mounting bracket 213, and being slidably disposed relative to the first arc groove 2111 to adjust the illumination angle of the light source 22. When the beam angle of the light source 22 needs to be adjusted, the first slide post 212 slides into the first arc groove 2111 and at different positions of the first arc groove 2111, so that a beam angle of the light source 22 is realized.Specifically, the first mounting bracket 213 includes a first plate body 2131 and a second plate body 2132 which are separated and disposed on opposite sides of the first adjustment frame 211, the second plate body 2132 is used for installing the light source 22, the set screw 215 connects the first plate body 2131 and the second plate body 2132, and is passed through the first arc groove 2111 and can also slide in the first arc groove 2111, and the first slide post 212 is a pin and also slides in the first arc groove 2111. Thus, by arranging the pin to slide in the first arc groove 2111 in association with the sliding movement of the set screw 215, since the pin abuts against and can slide on the groove wall of the first arc groove 2111, the accuracy of the light source 22 in the first arc groove 2111 in sliding is improved.Reference is made to FIGS. 7 and 8. The first adjustment structure 21 further includes an adjustment screw 214 connected between the first mounting bracket 213 and the light source 22 and for adjusting the height of the light source 22.
