Description
Technical Field
[0001] This utility model relates to the field of battery testing technology, and in particular to a testing device for testing the appearance of battery modules. Background Technology
[0002] With the rapid development of the new energy industry, battery modules, as core components of electric vehicles and energy storage systems, directly affect product performance and safety due to their appearance quality. During the production process, issues such as surface scratches, dimensional deviations, and assembly defects can lead to hidden dangers such as internal short circuits and poor heat dissipation. Therefore, higher requirements are placed on the accuracy and stability of appearance inspection equipment.
[0003] However, most traditional inspection equipment used for inspecting the appearance of battery modules uses fixed-size fixtures or positioning structures, which are only suitable for battery modules of specific specifications. When producing products of different models or sizes, it is necessary to frequently change the fixtures, which makes the operation cumbersome and time-consuming, and reduces the inspection efficiency.
[0004] For example, on a new energy vehicle battery production line, due to changes in market demand, the company needs to test battery modules of different capacities and sizes. The fixtures of traditional testing equipment cannot be adapted to the size of the new modules, so the staff has to stop the production line, disassemble and replace the special fixtures, a process that consumes a lot of time. Utility Model Content
[0005] This utility model discloses an inspection device for inspecting the appearance of battery modules, aiming to solve the technical problems in traditional inspection devices for inspecting the appearance of battery modules, which mostly use fixed-size fixtures or positioning structures, and are only suitable for battery modules of specific specifications. When producing products of different models or sizes, it is necessary to frequently change the fixtures, resulting in cumbersome and time-consuming operation and reduced inspection efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An inspection device for inspecting the appearance of battery modules includes a workbench, a conveyor belt fixed to the top outer wall of the workbench, a fixed base connected to the top outer wall of the conveyor belt, two symmetrically distributed supports connected to the top outer wall of the workbench, and two cameras connected to one side outer wall of each support, wherein the upper camera has a tilt angle of 30 degrees. The device also includes: a fixing mechanism located on both sides of the fixed base; and an adjustment mechanism including transmission gears installed inside the fixed base, with two symmetrically distributed connecting strips connected inside the fixed base. The connecting strip has multiple equidistant pawls on one outer wall and multiple equidistant locking blocks on the other outer wall. The outer walls of the locking blocks are connected to the outer wall of the transmission gear, and the locking blocks and the transmission gear mesh with each other. The bottom outer wall of the connecting strip has a first limiting block, and one outer wall of the connecting strip has a second limiting block. The top outer wall of the second limiting block has a clamping block. The fixed base has an internal mounting groove and a sliding groove on its top outer wall. Cleaning mechanism: The cleaning mechanism is located on the top outer wall of the camera.
[0008] In this solution, the battery module is placed on the top outer wall of the fixing base. One of the clamping blocks, slidably connected to the top outer wall of the fixing base, is then pushed to move. Simultaneously, a clamping block is connected to the top outer wall of the second limiting block, and a connecting strip is connected to one side outer wall of the second limiting block. This allows the connecting strip to move along with the clamping block. A transmission gear is rotatably connected inside the fixing base, and multiple locking blocks equidistantly distributed on the outer walls of the transmission gear and the two connecting strips mesh with each other. The movement of one connecting strip drives the transmission gear to rotate, which in turn drives the other connecting strip to move. The opposing movement of the two connecting strips causes the two clamping blocks to move towards each other until they are pressed against the two outer walls of the battery module, clamping the battery module to the top outer wall of the fixing base.
[0009] In a preferred embodiment, the fixing mechanism includes push blocks mounted on the outer walls of both sides of the fixing seat. A support bar is connected to one outer wall of the push block. A fixing rod is connected to one end of the support bar near the push block.

A fixing block is connected to the end of the support bar away from the push block. The outer wall of the fixing block fits into the groove formed between the two pawls.
[0010] In this solution, pressing the button compresses the spring, which in turn moves the support bar around the fixed rod, causing the fixed block at the other end of the support bar to disengage from the slot formed by the two pawls, thereby releasing the connection bar from its fixation.
[0011] In a preferred embodiment, the cleaning mechanism includes a motor mounted on the top outer wall of the camera. The output end of the motor is connected to a first bevel gear, and a second bevel gear is connected to the outer wall of the first bevel gear away from the motor. The first and second bevel gears mesh. A screw is connected to the bottom outer wall of the second bevel gear, and a connecting plate is connected to the outer wall of the screw. A plurality of equally spaced brushes are connected to the outer wall of the connecting plate near the camera. Two symmetrically distributed limiting grooves are provided on the outer wall of the camera near the connecting plate, and both ends of the connecting plate are connected to the inner walls of the limiting grooves.
[0012] In this design, when dust appears on the camera lens, the motor is activated, causing the first bevel gear connected to the motor output to move. A second bevel gear is connected to one side of the outer wall of the first bevel gear, and the two gears mesh with each other, causing the first bevel gear to rotate. A screw is connected to the bottom outer wall of the second bevel gear, and a connecting plate is threaded onto the outer wall of the screw. The two ends of the connecting plate are slidably connected to the inner wall of the limiting groove, causing the second bevel gear to rotate the screw. This allows the connecting plate to move up and down within the limiting groove. Multiple brushes are evenly distributed on the outer wall of the connecting plate near the camera, cleaning the camera lens as the connecting plate moves up and down.
[0013] As described above, an inspection device for inspecting the appearance of a battery module includes a workbench. A conveyor belt is fixed to the top outer wall of the workbench, and a fixed base is connected to the top outer wall of the conveyor belt. Two symmetrically distributed supports are connected to the top outer wall of the workbench, and two cameras are connected to one side outer wall of each support. The upper camera has a tilt angle of 30 degrees. The device also includes: a fixing mechanism located on both sides of the fixed base; and an adjustment mechanism including transmission gears installed inside the fixed base. The fixed base has two symmetrically distributed supports connected inside. The connecting strip has multiple equidistant pawls connected to one outer wall and multiple equidistant locking blocks connected to the other outer wall. The outer walls of the locking blocks are connected to the outer wall of the transmission gear, and the locking blocks and the transmission gear mesh with each other. A first limiting block is connected to the bottom outer wall of the connecting strip, a second limiting block is connected to one outer wall of the connecting strip, and a clamping block is connected to the top outer wall of the second limiting block. The fixing seat has an internal mounting groove and a sliding groove on its top outer wall. A cleaning mechanism is located on the top outer wall of the camera.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0023] The inspection device for inspecting the appearance of battery modules disclosed in this utility model is mainly applied to traditional inspection devices for inspecting the appearance of battery modules. Most of these devices use fixed-size fixtures or positioning structures, which are only suitable for battery modules of specific specifications. When producing products of different models or sizes, it is necessary to frequently change the fixtures, which leads to cumbersome and time-consuming operation and reduces inspection efficiency.
[0024] Reference Figure 1 , Figure 2 and Figure 3 An inspection device for inspecting the appearance of a battery module includes a worktable 1, a conveyor belt 2 fixed to the top outer wall of the worktable 1, a fixed base 4 connected to the top outer wall of the conveyor belt 2, two symmetrically distributed supports 3 connected to the top outer wall of the worktable 1, and two cameras 14 connected to one side outer wall of the supports 3, wherein the upper camera 14 has an tilt angle of 30 degrees. The device also includes: a fixing mechanism located on both sides of the fixed base 4; and an adjustment mechanism including transmission gears 6 installed inside the fixed base 4, with two pairs of gears 6 connected inside the fixed base 4. The connecting strip 7 is distributed in a manner that includes multiple pawls 10 evenly distributed on one side of its outer wall and multiple locking blocks 11 evenly distributed on the other side of its outer wall. The outer walls of the locking blocks 11 are connected to the outer walls of the transmission gear 6, and the locking blocks 11 and the transmission gear 6 mesh with each other. The bottom outer wall of the connecting strip 7 is connected to a first limiting block 12, and one side of the outer wall of the connecting strip 7 is connected to a second limiting block 13. The top outer wall of the second limiting block 13 is connected to a clamping block 9. The fixed base 4 has an installation groove 8 inside and a sliding groove 5 on the top outer wall of the fixed base 4. The cleaning mechanism is located on the top outer wall of the camera 14.
[0025] By placing the battery module on the top outer wall of the fixing base 4, one of the clamping blocks 9, which is slidably connected to the top outer wall of the fixing base 4, is pushed to move. At the same time, the top outer wall of the second limiting block 13 is connected to the clamping block 9, and one side outer wall of the second limiting block 13 is connected to the connecting strip 7. This allows the connecting strip 7 to move together with the clamping block 9. At this time, the transmission gear 6 is rotatably connected to the inside of the fixing base 4, and multiple locking blocks 11, which are equidistantly distributed on the outer walls of the transmission gear 6 and the two connecting strips 7, mesh with each other. This allows the movement of one connecting strip 7 to drive the transmission gear 6 to rotate, and the rotation of the transmission gear 6 to drive the other connecting strip 7 to move accordingly. At this time, the two connecting strips 7 move towards each other, so that the two clamping blocks 9 move towards each other until they are attached to the two outer walls of the battery module, clamping the battery module on the top outer wall of the fixing base 4.
[0026] The connecting bar 7, the first limiting block 12, multiple pawls 10 and multiple locking blocks 11 are all installed inside the mounting groove 8. The mounting groove 8 is used to provide installation space for the internal components and to limit their movement.
[0027] Specifically, the transmission gear 6 is located at the center point of the fixed base 4. By installing the transmission gear 6 at the center point of the fixed base 4, the connecting strips 7 connected to the outer wall of the transmission gear 6 are symmetrically distributed inside the fixed base 4, thereby ensuring the uniform transmission of force.
[0028] Reference Figure 2 and Figure 6 In a preferred embodiment, the fixing mechanism includes push blocks 25 installed on the outer walls of both sides of the fixing base 4. A support bar 26 is connected to one outer wall of the push block 25. A fixing rod is connected to one end of the support bar 26 near the push block 25. The two ends of the fixing rod are connected to the inside of the fixing base 4. A spring 24 is connected to the outer wall of the support bar 26 away from the push block 25. A fixing block 27 is connected to the end of the support bar 26 away from the push block 25. The outer wall of the fixing block 27 fits into the groove formed between the two pawls 10.
[0029] By pressing the button 25, the spring 24 is compressed, which in turn causes the support bar 26 to move around the fixed rod, thereby causing the fixing block 27, which is fixedly connected to the other end of the support bar 26, to disengage from the slot formed by the two pawls 10, and thus release the fixation of the connecting bar 7.
[0030] Both the pawl 10 and the fixing block 27 are barbed structures, and the surfaces of the pawl 10 and the fixing block 27 that come into contact with each other are curved surfaces. Through the engagement of the pawl 10 and the fixing block 27, a one-way locking effect is provided during the fixing of the battery module. After the clamping block 9 moves the connecting strip 7 to complete the clamping of the battery module, the pawl 10 can slide along the barbed slope of the fixing block 27. When the pawl 10 slides into the slot of the fixing block 27, the barbed structures of the two form a mechanical lock to prevent the clamping block 9 from retracting due to external force or vibration, and to ensure that the battery module remains in a stable and fixed state during the testing process.
[0031] Reference Figure 4 , Figure 5 and Figure 7 In a preferred embodiment, the cleaning mechanism includes a motor 15 mounted on the top outer wall of the camera 14. The output end of the motor 15 is connected to a first bevel gear 16. A second bevel gear 17 is connected to the outer wall of the first bevel gear 16 away from the motor 15. The first bevel gear 16 and the second bevel gear 17 mesh. A screw 21 is connected to the bottom outer wall of the second bevel gear 17. A connecting plate 23 is connected to the outer wall of the screw 21. A plurality of equally spaced brushes 22 are connected to the outer wall of the connecting plate 23 near the camera 14. Two symmetrically distributed limiting grooves are provided on the outer wall of the camera 14 near the connecting plate 23. The two ends of the connecting plate 23 are connected to the inner wall of the limiting grooves.
[0032] When dust appears on the lens of the camera 14, the motor 15 is started, which drives the first bevel gear 16 connected to the output end of the motor 15 to move together. At this time, the second bevel gear 17 is connected to one side of the outer wall of the first bevel gear 16, and the first bevel gear 16 and the second bevel gear 17 mesh with each other, so that the first bevel gear 16 drives the second bevel gear 17 to rotate. At this time, the screw 21 is connected to the bottom outer wall of the second bevel gear 17, and the connecting plate 23 is threaded to the outer wall of the screw 21. The two ends of the connecting plate 23 are slidably connected to the inner wall of the limiting groove, so that the second bevel gear 17 drives the screw 21 to rotate, thereby realizing the up and down movement of the connecting plate 23 in the limiting groove. At this time, multiple brushes 22 are evenly distributed on the outer wall of the connecting plate 23 near the camera 14, so that the brushes 22 clean the lens of the camera 14 as the connecting plate 23 moves up and down.
[0033] A dust cover 19 is connected to one side of the outer wall of the camera 14. A support plate 18 is connected to the bottom outer wall of the camera 14 away from the motor 15. A collection box 20 is connected to one side of the outer wall of the support plate 18. Multiple connecting blocks are installed on the outer wall of the collection box 20. The motor 15 is inserted into the support plate 18 through the multiple connecting blocks, thereby installing the motor 15 inside the support plate 18 and collecting the dust scraped off by the brush 22.
[0034] Working principle: In use, the battery module is first placed on the top outer wall of the fixing base 4. The operator manually pushes one of the clamping blocks 9 installed on the top outer wall of the fixing base 4. Since the top of the second limiting block 13 is connected to the clamping block 9 and one side is connected to the connecting strip 7, the movement of the clamping block 9 will drive the connecting strip 7 to move together. At this time, the bottom of the transmission gear 6 is rotated and connected to the inside of the fixing base 4 and located at the center point. At the same time, the outer wall of the transmission gear 6 and the multiple locking blocks 11 distributed at equal distances on the outer walls of the two connecting strips 7 mesh with each other. When one of the connecting strips 7 moves, the meshing relationship between the locking blocks 11 and the transmission gear 6 will drive the transmission gear 6 to rotate. The rotation of 6 will drive the other connecting bar 7 to move in the opposite direction, ultimately causing the two clamping blocks 9 to move towards each other until they are pressed against the outer walls of both sides of the battery module, clamping and fixing the battery module. During this process, the transmission gear 6 is installed at the center point of the fixing base 4, ensuring that the two connecting bars 7 are symmetrically distributed, so that the force can be transmitted evenly and the battery module is stably clamped. After the clamping block 9 drives the connecting bar 7 to move and complete the clamping of the battery module, the pawl 10 can slide along the barbed ramp of the fixing block 27 and slide into the slot of the fixing block 27. The barbed structure of the two forms a mechanical lock to prevent the clamping block 9 from retracting due to external force or vibration, ensuring that the battery module remains stable during the testing process. In the fixed state, if it is necessary to release the battery module, press the button 25, the spring 24 is compressed, the support bar 26 moves around the fixing rod, causing the fixing block 27 to disengage from the slot formed by the two pawls 10, thereby releasing the fixing of the connecting bar 7. At this time, the conveyor belt 2 is started to drive the fixing seat 4 into the detection area. At this time, two cameras 14 are installed on the two brackets 3 on the top of the workbench 1. The upper camera 14 is tilted at a 30-degree angle. This multi-angle setting can comprehensively capture the appearance details of the battery module at different positions and angles. When the battery module enters the detection area, the two cameras 14 are started simultaneously to acquire images of the appearance of the battery module and obtain high-definition images. As shown in the data, when dust appears on the lens of camera 14, motor 15 is activated. The output end of motor 15 is connected to the first bevel gear 16. The operation of motor 15 drives the first bevel gear 16 to move together. The first bevel gear 16 meshes with the second bevel gear 17, and the outer wall of one side of the first bevel gear 16 is connected to the second bevel gear 17. Thus, the rotation of the first bevel gear 16 drives the rotation of the second bevel gear 17, and the direction of motion is changed through bevel gear transmission. At this time, a screw 21 is connected to the bottom outer wall of the second bevel gear 17. The outer wall of the screw 21 is threadedly connected to a connecting plate 23. At the same time, the two ends of the connecting plate 23 are slidably connected to the inner wall of the limiting groove on camera 14. When the second bevel gear 17 drives the screw 21 to rotate, due to the limiting effect of the threaded transmission and the limiting groove, the connecting plate 23 moves up and down in the limiting groove. Multiple brushes 22 are evenly distributed on the outer wall of the connecting plate 23 near camera 14. As the connecting plate 23 moves up and down, the brushes 22 clean the lens of camera 14 and remove the dust from the lens surface.The dust cover 19 on one side of the camera 14 can reduce dust adhesion. During the cleaning process, the dust scraped off by the brush 22 falls into the collection box 20, realizing the collection and treatment of dust and keeping the detection environment clean.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
