[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figure 1-3 As shown, this application provides a visual inspection device for battery module terminals, including a body 1. Two visual inspection cameras 4 are installed inside the body 1. The cameras have automatic focusing and image enhancement functions and can capture the features of battery module terminals. To adapt to the inspection requirements of battery module terminals of different specifications, adjustment components 2 are provided on both sides inside the body 1.

[0034] like Figure 4 As shown, the adjustment assembly 2 includes support plates 21 that are bolted to both sides inside the body 1. The support plates 21 are made of high-strength aluminum alloy, which has good strength and lightweight characteristics. Guide rails 22 are fixedly installed on opposite sides of the two support plates 21. Adjustment screws 23 are rotatably installed inside the guide rails 22. The surface of the screws is precision ground and hardened to ensure transmission accuracy and wear resistance.

[0035] A first slider 24 is slidably mounted on the guide rail 22. The first slider 24 is connected to the adjusting screw 23 by a nut (not shown in the figure). The upper end of the adjusting screw 23 passes through the guide rail 22 and is fixedly mounted with a rotating handle 25 wrapped with anti-slip rubber (not shown in the figure), which makes it easy for the operator to rotate the adjusting screw 23.

[0036] A first limiting block 26 and a second limiting block 27 are fixedly installed on both sides of the outer wall of the slider by bolts. Both the first limiting block 26 and the second limiting block 27 are made of high-hardness engineering plastic, which has a certain degree of toughness and wear resistance. The upper and lower ends of the first limiting block 26 and the second limiting block 27 are fixedly connected by bolts. The first limiting block 26 has a first semi-circular groove 29 inside, and the second limiting block 27 has a second semi-circular groove 28 inside. A circular groove is formed between the first semi-circular groove 29 on the first limiting block 26 and the second semi-circular groove 28 on the second limiting block 27.

[0037] like Figure 4-5 As shown, a connecting plate 210 is fixed on one side of the visual inspection camera 4, and a circular locking block 211 is fixed on one side of the connecting plate 210. The circular locking block 211 on the connecting plate 210 is snapped into the circular slot and can rotate flexibly in the circular slot, thereby achieving precise adjustment of the rotation angle of the visual inspection camera 4.

[0038] A fastening bolt 212 is provided on one side of the first limiting block 26. The fastening bolt 212 is threadedly connected to the threaded hole (not shown in the figure) on the first limiting block 26. One end of the fastening bolt 212 passes through the first limiting block 26 and fits tightly with the circular locking block 211. By tightening the fastening bolt 212, the rotation position of the circular locking block 211 can be locked to ensure that the camera remains stable during the detection process.

[0039] like Figure 2-3 As shown, the internal structure of the machine body 1 has two moving components 3. The moving component 3 includes an electric slide rail 31 fixedly installed inside the machine body 1. A second slider 32 is slidably connected to the electric slide rail 31. The second slider 32 is threadedly connected to a drive screw (not shown in the figure) inside the electric slide rail 31. A placement platform 33 is fixedly installed on the second slider 32. The surface of the placement platform 33 is provided with an anti-slip rubber pad (not shown in the figure) for accurately placing the battery module terminals to be tested.

[0040] like Figure 1 As shown, protective doors 5 are hinged to both sides of the machine body 1. The protective doors 5 are made of transparent high-strength acrylic material, which makes it easy to observe the internal testing process. A PLC control panel 6 is fixed at the top of the machine body 1. Operators can easily set testing parameters, start and stop the testing program, and view the testing results through the PLC control panel 6.

[0041] The PLC control panel 6 incorporates advanced image processing algorithms and data analysis software, enabling rapid processing and analysis of images captured by the visual inspection camera 4. It automatically determines whether there are defects in the battery module terminals and generates detailed inspection reports. Adjustable height support legs 7 are installed at the four corners of the lower part of the machine body 1. The bottom of the support legs 7 is equipped with anti-slip rubber pads to adapt to different ground conditions and ensure the stability of the equipment during operation.

[0042] Working Principle: When facing the need to inspect battery module terminals of different specifications, the operator first adjusts the position and angle of the visual inspection camera 4 using the adjustment component 2. Holding the rotating handle 25, which is covered with anti-slip rubber at the upper end of the adjusting screw 23, and rotating it clockwise or counterclockwise, the operator utilizes the threaded transmission principle of the screw and nut to allow the first slider 24 to slide precisely vertically on the guide rail 22. Since the visual inspection camera 4 engages with the circular slot formed by the circular locking block 211 on the connecting plate 210 and the first limiting block 26 and the second limiting block 27, the movement of the first slider 24 causes the camera to rise and fall synchronously, achieving vertical position adjustment to match battery module terminals of different heights.

[0043] After completing the vertical position adjustment, if it is necessary to adjust the camera's shooting angle, the fastening bolt 212 on one side of the first limit block 26 can be loosened to release the lock on the circular locking block 211. At this time, the circular locking block 211 on the connecting plate 210 can rotate flexibly within the circular slot formed by the first semicircular groove 29 and the second semicircular groove 28. The operator can manually fine-tune the camera angle according to the actual testing requirements so that the camera can capture the details of the battery module terminals from the best perspective. After the angle is adjusted to the correct position, tighten the fastening bolt 212 so that one end fits tightly against the circular locking block 211. The tightening force of the threaded connection locks the rotation position of the camera, ensuring that the camera will not shift or shake during subsequent testing.

[0044] Meanwhile, the operator sets the operating parameters of the electric slide rail 31 according to the size and shape of the battery module terminals to be tested via the PLC control panel 6. The PLC control panel 6 transmits control commands to the drive system inside the electric slide rail 31. The drive screw starts to rotate under the drive of the motor, and the second slider 32, which is threadedly connected to the drive screw, slides smoothly on the electric slide rail 31, moving the placement platform 33, which is fixedly installed on it, to the appropriate position. The anti-slip rubber pad on the surface of the placement platform 33 can effectively increase the friction between the platform and the battery module terminals, ensuring that the terminals remain stable during placement and testing and will not shift due to vibrations generated by the operation of the equipment.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
