Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to a testing mechanism. Background Technology

[0002] In battery production, the battery surface needs to be painted. Painting is a crucial surface treatment step, primarily used for purposes such as corrosion protection, insulation, aesthetics, or labeling of the battery casing or specific components. However, during the painting process, defects may occur in the paint film due to fluctuations in process parameters (such as spraying distance, air pressure, and paint viscosity), environmental factors (such as temperature, humidity, and dust), or equipment conditions (such as nozzle blockage and mechanical deviations). These defects include uneven thickness, bubbles, particles, runs, missed areas, or color differences. These defects not only affect the product's appearance quality but may also reduce the protective performance of the paint film, thereby impacting the long-term reliability and safety of the battery.

[0003] However, the current industry standard for testing the surface quality of batteries requires a separate testing workbench. Each battery needs to be transferred to the testing workbench separately, which is a cumbersome process that seriously affects production efficiency. Furthermore, the transfer process can easily cause product damage, affecting the product yield. Utility Model Content

[0023] In the current technology, the industry requires a separate inspection workbench to inspect the surface quality of batteries. Each battery needs to be transferred to the inspection workbench separately, which is a complicated process that seriously affects production efficiency. In addition, the transfer process can easily cause product damage, affecting the product yield.

[0024] This utility model proposes a testing mechanism.

[0025] Please see Figures 1 to 4In one embodiment of this utility model, the detection mechanism includes: a frame 100, a conveyor line 700, a rotating component 300, and a lifting component 400. The frame 100 is equipped with a detection camera for acquiring surface information of the product 600 to be tested. The conveyor line 700 is located on the frame 100 and is used to convey the product 600 to be tested. The rotating component 300 is located on the frame 100 and above the conveyor line 700, and is used to clamp the product 600 to be tested and drive it to rotate. The lifting component 400 includes a lifting drive module 410 and a lifting frame 420. The lifting drive module 410 is located on the frame 100, and the lifting frame 420 drive module is connected to the lifting frame 420 and drives the lifting frame 420 to move vertically, causing the product 600 to reciprocate between the conveyor line 700 and the detection position. At the detection position, the detection camera scans the product 600 to be tested.

[0026] It should be noted that, in specific implementation, the product under test 600 can be a cylindrical battery or other product adapted to the conveyor line 700. The conveyor line 700 can be a roller-axis type or other conveyor line adapted to the product under test 600; this embodiment is not limited to any particular type. The rotating component 300 can clamp the product under test 600 while simultaneously driving it to rotate, so that during the rotation of the product under test 600, the detection camera can acquire surface information of the entire circumferential surface of the product under test 600. The detection camera can be a 3D laser camera or other detection cameras; this embodiment is not limited to any particular type.

[0027] In this embodiment, the conveyor line 700, the rotating assembly 300, and the lifting assembly 400 are all fixedly mounted on the frame 100. The rotating assembly 300 is located above the conveyor line 700. The lifting assembly 400 lifts the product under test 600 to the detection position. A detection camera is also mounted on the frame 100. The detection camera scans the surface of the product under test 600 to obtain surface information. The lifting assembly 400 lifts the product under test 600 from the conveyor line 700 to the detection position for detection. The detection position can include multiple locations, set according to the actual location of the product under test 600 to be detected and the detection program. The detection positions include those corresponding to the rotating assembly 300. A detection camera is located above the rotating assembly 300. When the lifting assembly 400 lifts the product under test 600 to the position corresponding to the rotating assembly 300, the rotating assembly 300 clamps the product under test 600 and simultaneously drives it to rotate. During this rotation, the detection camera acquires surface information of the outer peripheral surface of the product under test 600. Additionally, it can be understood that the detection positions also include those away from the rotating assembly 300. At these positions, detection cameras are located on both sides of the frame 100. These cameras acquire surface information of the two end faces of the product under test 600, thereby completing the detection of the entire outer surface of the product under test 600.

[0028] The lifting drive module of the lifting component 400 adopts a servo motor screw structure or cylinder structure, and is vertically fixed on the frame 100. The lifting frame 420 is L-shaped. The lifting drive module 410 drives the frame 100 to move up and down in the vertical direction to realize the transfer of the product under test 600.

[0029] This utility model's technical solution uses a frame 100 as a support, and a detection camera is set on the frame 100 to detect and acquire the surface information of the product 600 under test. The product 600 is transported via a conveyor line 700 to simplify the detection process. Specifically, a lifting drive module 410 drives a lifting frame 420 to move up and down, causing the product to reciprocate between the conveyor line 700 and the detection position, facilitating the detection camera's scanning of the product 600. A rotating component 300 corresponds to the detection position. When the lifting drive module 410 lifts the product 600 to the detection position, the rotating component 300 also clamps the product 600 and drives it to rotate. During this rotation, the detection camera acquires the surface information of the product 600. Thus, the surface quality inspection of the product 600 can be completed while it is being transported by the conveyor line 700, improving production efficiency and reducing the risk of product damage.

[0030] In one embodiment, the lifting frame 420 is provided with a groove 421, which is adapted to the product under test 600 and is used to accommodate the product under test 600, and the groove 421 is provided in a one-to-one correspondence with the product under test 600.

[0031] Specifically, the top end face of the lifting frame 420 has a groove 421. There are multiple grooves 421, and the multiple grooves 421 are spaced apart. The distance between the grooves is adapted to the distance between the products 600 to be tested. In this way, the lifting component 400 can lift multiple products 600 to be tested in one operation, thereby improving the testing efficiency and production efficiency.

[0032] refer to Figure 4 As shown, the lifting frame 420 further includes a lifting plate 422 and two sets of toothed plates 423 disposed on the lifting plate 422. The lifting plate 422 is connected to the lifting drive module 410. The two sets of toothed plates 423 are arranged side by side. A groove 421 is disposed on the toothed plate 423, and the groove opening is located on the side of the toothed plate 423 away from the lifting plate 422. The grooves 421 of the two sets of toothed plates 423 are arranged opposite to each other, and the two opposite grooves 421 are used to accommodate the same product 600 to be tested.

[0033] Specifically, the lifting drive module 410 is connected to the lifting plate 422. In order to ensure the stability when lifting the product under test 600, in this embodiment, the lifting plate 422 is provided with two sets of toothed plates 423 arranged side by side. The top of the toothed plate 423 is provided with a groove 421. The two opposite grooves 421 on the two toothed plates 423 accommodate the same product under test 600, thereby improving the stability of the product under test 600 when lifting.

[0034] In one embodiment, the detection mechanism further includes a controller and a memory. The controller is communicatively connected to the detection camera, which transmits surface information to the controller. The controller calculates and analyzes the surface information, and the memory is communicatively connected to the controller and used to store the surface information.

[0035] In the specific implementation process, the inspection camera may be a 3D laser camera, a 2D camera, or other types of camera, designed according to the actual product requirements; no limitation is made in this embodiment. The inspection camera scans the surface of the product under test (600) to acquire surface information and outputs a brightness map and a height map. After the controller acquires the brightness map, it uses deep learning to find the defect area and maps it to the height map. By filtering out a certain number of the highest and lowest points in the defect area on the height map, and by fitting a reference plane with several points around the defect area, the distance from the defect point to the plane is calculated. The difference between the distance and a preset threshold is determined, thereby determining whether it is a defect or a good product. In addition, the surface information of the acquired brightness map and depth map, as well as the data of the analysis and calculation, are stored in the memory for easy retrieval and verification.

[0036] In one embodiment, the detection camera includes a first camera 200 and a second camera. There are two second cameras, which scan both ends of the product under test 600 respectively. The first camera 200 is located above the product under test 600 and is used to scan the outer peripheral surface of the product under test 600.

[0037] It should be noted that surface inspection requires testing the peripheral surface and both end faces of the product under test 600. In practice, the first camera 200 is positioned above the product under test 600, which is rotated by the rotating assembly 300, and acquires surface information of the entire outer peripheral surface during the rotation of the product under test 600. The second camera is located on the frame 100, and captures images of the end faces of the product under test 600 when the lifting assembly 400 drives the product under test 600 to rise and it is positioned between the conveyor line 700 and the rotating assembly 300, or above the rotating assembly 300.

[0038] Furthermore, in this embodiment, the detection position includes a first detection position and a second detection position. At the first detection position, the rotating component 300 clamps the product under test 600, and the first camera 200 scans the outer peripheral surface of the product under test 600. At the second detection position, the second camera scans the end face of the product under test 600.

[0039] Understandably, when the lifting component 400 drives the product under test 600 away from the conveyor line 700 and rises to a position corresponding to the rotating component 300, this position serves as the first detection position of the product under test 600. The lifting component 400 then drives the product under test 600 to a position between the conveyor line 700 and the rotating component 300, or to a position above the rotating component 300, which serves as the second detection position of the product under test 600. In specific implementation, the lifting component 400 can either drive the product under test 600 to the first detection position first, and then drive it to the second detection position after detection, or it can first drive the product under test 600 to the second detection position, and then move it to the first detection position for detection after detection. This embodiment does not impose any limitations; it can be determined according to the actual production design.

[0040] refer to Figure 2 and Figure 3 As shown, in one embodiment, the rotating assembly 300 includes a rotating shaft 310, an active clamping part 320, and a fixed clamping part 330. Both the active clamping part 320 and the fixed clamping part 330 are provided with a rotating shaft 310. At the first detection position, the active clamping part 320 and the fixed clamping part 330 approach each other to clamp the product under test 600, and the rotating shaft 310 drives the product under test 600 to rotate.

[0041] In this embodiment, the active clamping part 320 and the fixed clamping part 330 are arranged opposite to each other, with the product to be tested 600 located between them. The active clamping part 320 provides clamping power, causing the active clamping part 320 and the passive clamping part to move closer together and clamp the product to be tested 600. In specific implementation, both the active clamping part 320 and the fixed clamping part 330 are equipped with cylinders, and the cylinders are connected to clamping plates. The cylinders drive the two clamping plates to move closer together and clamp the product to be tested 600. Alternatively, the active clamping part 320 is equipped with a motor, and the motor is connected to a lead screw. Both the active clamping part 320 and the fixed clamping part 330 are equipped with clamping plates and connected to the lead screw. The threads on the lead screw connecting the two clamping plates have opposite directions. In this way, the motor drives the lead screw to rotate, causing the two clamping plates to move closer together to clamp the product to be tested 600 or move away from each other to release it. In addition, a rotating shaft 310 is provided on the clamping plate and is rotatably connected to the clamping plate. The movement of the clamping plate drives the rotating shaft 310 to move synchronously.

[0042] In one embodiment, the rotating shaft 310 is connected to a drive assembly, which includes a drive shaft 350 and a magnetic wheel 340. Both the drive shaft 350 and the rotating shaft 310 are provided with magnetic wheels 340, and the magnetic wheels 340 drive the rotating shaft 310 to rotate through magnetic force.

[0043] In practical implementation, the drive shaft 350 extends along the direction of multiple rotating shafts 310 arranged in parallel. Magnetic wheels 340 are spaced apart on the drive shaft 350, and magnetic wheels 340 are also provided on the rotating shafts 310. The drive shaft 350 is also connected to a motor, which drives the drive shaft 350 to rotate. Under the action of the magnetic wheels 340, the multiple rotating shafts 310 are driven to rotate synchronously. Of course, the drive shaft 350 can be located in the active clamping part 320 or the fixed clamping part 330, and the rotating shafts 310 that cooperate with the drive shaft 350 are equipped with magnetic wheels 340.

[0044] refer to Figure 1 and Figure 2 As shown, in one embodiment, the testing mechanism further includes a purging assembly 500, which includes a purging pipe 510 and an air nozzle 520 disposed on the purging pipe 510. The purging pipe 510 is disposed on the frame 100, and the air nozzle 520 blows air towards the product 600 to be tested. In specific implementation, it is understood that the purging pipe 510 is externally connected to an air pump or gas pipeline to provide gas to the purging pipe 510. The gas passes through the purging pipe 510 and is blown out from the air nozzle 520 to purge the product 600 to be tested, avoiding dust and other debris on the surface of the product 600 from affecting the testing. The purging pipe 510 adopts a universal curved pipe, which can arbitrarily adjust the position and purging direction of the purging pipe 510 and the air nozzle 520 to adapt to different needs. Furthermore, multiple purging pipes 510 are provided, and the positions of the air nozzles 520 are reasonably set to ensure that the entire outer periphery of the product 600 to be tested can be purged. In this embodiment, before the detection camera detects the product under test 600, the surface is first blew by the purging component 500 to avoid debris affecting the detection.

[0045] In one embodiment, the frame 100 includes a support frame 120 and a testing frame 110. The testing frame 110 is disposed on the support frame 120. The conveyor line 700, the rotating component 300, and the lifting component 400 are all disposed on the support frame 120. The testing camera is connected to a base 130, which is disposed on the testing frame 110. The testing frame 110 is also provided with a hanger, and the hanger is provided with a light source 140, which illuminates the product 600 to be tested.

[0046] Specifically, the support frame 120 serves as the support for the entire mechanism and includes multiple interconnected square steel or channel steel, etc. The inspection frame 110 forms a gantry structure, and the base 130 is fixed on the inspection frame 110 to suspend and fix the inspection camera. The hanger is connected to the inspection frame 110 and is equipped with a light source 140. The light source 140 cooperates with the inspection camera to provide light for inspection and improve the accuracy of inspection.
