In the following description, many specific details are set forth to facilitate a full understanding of the utility model.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Battery separators are important components in battery production. Their material properties directly affect the quality of the battery. During the production process, battery separators need to be fully tested, including thickness testing.

[0025] Since the battery diaphragm is relatively thin, the traditional detection process is to use a thickness meter to measure the thickness of the battery diaphragm. During the detection process, the battery diaphragm is cut into a predetermined size and placed on the detection platform of the meter. The detection probe is manually adjusted to different positions on the diaphragm surface to achieve continuous detection of the thickness of different areas on the diaphragm surface.

[0026] The traditional manual inspection method has low inspection efficiency, and the inspection area on the surface of the battery diaphragm is completely manually aligned by the operator. The coverage and inspection accuracy of various areas on the surface of the battery diaphragm are poor. It is difficult to match the inspection position and thickness data during the inspection process, and the inspection results cannot meet the needs of high-precision inspection and analysis.

[0027] In order to solve the above problems, refer to the attached Figure 1 -Attached Figure 5A robot arm for battery diaphragm detection includes a mounting platform 100. A first arm assembly 400 for grabbing a detection platform 200 and a second arm assembly 500 for grabbing a detection probe 300 are arranged on the surface of the mounting platform 100. The first arm assembly 400 includes a telescopic structure for controlling the linear movement of the detection platform 200. The first arm assembly 400 and the second arm assembly 500 cooperate to realize automatic detection of the surface of the battery diaphragm, replacing manual operation, thereby greatly improving the efficiency of battery diaphragm detection.

[0028] Specifically; the second arm assembly 500 includes a rotating joint 520 and a detection end 510, and the detection probe 300 is installed at the bottom position of the detection end 510. The second arm assembly 500 and the detection platform 200 are arranged circumferentially around the rotation axis of the detection end 510. The detection platform 200 is controlled to move linearly during the rotation of the detection end 510 by the rotating joint 520 to complete the continuous detection of the thickness of the battery separator 700. During the rotation of the detection end 510 controlled by the rotating joint 520, the detection probe 300 at the end of the detection end 510 can contact multiple battery separators 700 in turn to complete the continuous automatic detection of the surface thickness of multiple battery separators 700, which greatly improves the detection. At the same time, through the cooperation of the first arm assembly 400 and the second arm assembly 500, all-round detection of various areas on the surface of the battery separator can be performed, and the thickness of the detection area can be summarized according to the background data of the first arm assembly 400, the second arm assembly 500, and the detection probe 300 to generate a distribution state diagram of the surface thickness of the battery separator 700, meeting the needs of all-round detection.

[0029] It should be noted here that the detection probe 300 at the end can be selected as a roller style, moving on the surface of different detection platforms 200 to detect the thickness of the battery separator 700. Similarly, a combination of a disc-shaped probe and a telescopic structure can be selected to cooperate with the telescopic structure during the rotation of the detection end 510 to complete continuous detection of different areas.

[0030] A negative pressure assembly is installed on the upper end of the detection platform 200 for gripping the battery separator 700 under negative pressure. The battery separator 700 is in a stable limited state on the upper end of the detection platform 200 to ensure the stability of the battery separator 700 during the thickness detection process.

[0031] The specific detection end 510 includes a first mounting arm 513 and a second mounting arm 511. The side wall of the first mounting arm 513 is fixed with a locking workpiece 512 for fixing the second mounting arm 511. The second mounting arm 511 and the first mounting arm 513 are slidably connected. Different second mounting arms 511 can be replaced according to different detection conditions to adaptively install different detection probes 300.

[0032] A mounting column 110 is fixed at the middle position of the upper end of the mounting platform 100, and the second arm assembly 500 is rotatably connected to the mounting column 110. The second arm assembly 500 rotates around the mounting column 110, and the position of the second arm assembly 500 can be located through the mounting column 110. The battery diaphragm 700 and the detection platform 200 are disposed on the outside of the mounting column 110 and are arranged circumferentially around the mounting column 110.

[0033] Preferably, the first arm assembly 400 is arranged at the bottom position of the mounting column 110, and the second arm assembly 500 is arranged at the top position of the mounting column 110. The first arm assembly 400 and the second arm assembly 500 are staggered, and the second arm assembly 500 can be located at an upper position to detect multiple battery separators 700 downward.

[0034] Specifically, the telescopic structure of the first arm assembly 400 is a hydraulic telescopic rod, and a pump fluid assembly 600 for controlling the extension of the hydraulic telescopic rod is also provided inside the rotating joint 520. When the rotating joint 520 controls the rotation of the detection end 510, the pump fluid assembly 600 is controlled to pump liquid into the hydraulic telescopic rod in a quantitative and timed manner, which can push the hydraulic telescopic rod to extend, and finally control the detection platform 200 to move linearly in a predetermined direction to complete the drive control.

[0035] By setting the above structure, the extension and retraction of the first arm assembly 400 is automatically controlled during the rotation control of the rotating joint 520, which simplifies the control structure and improves the control coordination accuracy of the first arm assembly 400 and the second arm assembly 500.

[0036] Specifically; the rotating joint 520 includes a rotating base 522 and a rotating ring 521 fixed relatively to the mounting platform 100, the pumping assembly 600 includes a pumping protrusion 610 fixed on the side wall of the rotating ring 521, and also includes a pumping bag 620 located on the rotating path of the pumping protrusion 610, the pumping bag 620 is elastic and is connected to the hydraulic telescopic rod. In the process of controlling the continuous rotation of the rotating ring 521, it can drive the pumping protrusion 610 to rotate synchronously to squeeze the corresponding pumping bag 620, and is connected to two pumping pipes with built-in one-way valves. The first pumping pipe is connected to the hydraulic telescopic rod, and the other pumping pipe is connected to the oil tank. In the process of periodic extrusion, one-way pumping of oil can be realized to control the extension of the hydraulic telescopic rod.

[0037] It should be noted here that the pump capsule 620 is arranged on the side opposite to the corresponding hydraulic telescopic rod. After the rotating ring 521 drives the detection probe 300 to rotate to the side away from the corresponding hydraulic telescopic rod, the corresponding pump capsule 620 is squeezed; a return oil pipeline with a built-in valve is connected between the pump capsule 620 and the oil tank to facilitate resetting the hydraulic telescopic rod and realize continuous thickness detection.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
