DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. 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.

[0022] Battery separator is an important material for battery production, and the uniformity of its transverse and longitudinal thickness is an important indicator of separator quality.

[0023] In the testing workshop, the diaphragm is usually sampled, and the thickness of multiple points on the diaphragm surface is tested by contact thickness testing instrument. Before each test, the battery diaphragm needs to be placed flat in a predetermined position to ensure the continuity and accuracy of the test.

[0024] In order to prevent the warping of the battery diaphragm from affecting the thickness detection, the battery diaphragm needs to be limited. The size of a single detection platform is limited, and only a limited area of ​​the battery diaphragm can be limited at a time. In the process of replacing the battery diaphragm for thickness detection, the battery diaphragm needs to be loaded and unloaded at intervals, which affects the efficiency of the battery diaphragm thickness detection.

[0025] Some designs extend the detection platform outward in the horizontal plane, and the same set of thickness detection elements are located at different positions in the horizontal plane to detect the thickness of the battery diaphragm, which can improve the efficiency of battery diaphragm thickness detection to a certain extent; however, designing multiple detection platforms in the horizontal plane occupies a large horizontal area, affecting the placement of more detection equipment; at the same time, the detection platforms in the horizontal plane are arranged circumferentially, and the battery diaphragms at different positions need to be loaded and unloaded in turn, causing inconvenience in operation.

[0026] In order to solve the above problems, refer to the attached Figure 1 -Attached Figure 4A diaphragm thickness detection device includes a detection mechanism 200 and a carrying device for carrying the diaphragm. The battery diaphragm is limited by the carrying device to ensure the stability and accuracy of the fixed position of the battery diaphragm. At the same time, the battery diaphragm is continuously tested for thickness by the detection mechanism 200 to determine whether the battery diaphragm meets the requirements.

[0027] Specifically, the bearing device includes a hollow bearing frame 100, a plurality of bearing openings 110 are opened on the surface of the bearing frame 100, a driving shaft 120 is installed on the first side of the bearing frame 100, and the plurality of bearing openings 110 are arranged circumferentially around the driving shaft 120; a bearing platform 300 is detachably connected to the bearing opening 110, the bearing opening 110 is connected inside and outside, and the diaphragm is fixed to the inner surface of the bearing platform 300, wherein the driving bearing frame 100 is driven to rotate and control different bearing platforms 300 to rotate to the detection position to complete the continuous detection of the diaphragm thickness, and when the thickness of the battery diaphragms on the surfaces of different bearing platforms 300 is detected, the driving shaft 120 is rotated by a predetermined angle so that the different bearing platforms 300 are located at the bottom position (towards the position of the detection mechanism 200), and the detection mechanism 200 is extended to continuously detect the thickness of the battery diaphragm surface at different positions to determine whether the thickness of the battery diaphragm meets the requirements; continuing the above operation can detect the thickness of the battery diaphragms at different positions.

[0028] Here, the rotation of the driving shaft 120 and the thickness detection of the detection mechanism 200 can be automatically performed by a manipulator. The staff only needs to disassemble and replace the tested supporting platform 300 and the battery diaphragm from the top position, which greatly improves the efficiency of battery diaphragm detection.

[0029] In summary, through the above-mentioned arrangement, multiple supporting platforms 300 are located in a virtual circle in the vertical space, will not occupy the horizontal space, and will not affect the layout of other detection equipment; at the same time, the automatic detection of the corresponding battery diaphragm thickness can be completed by controlling the supporting platform 300 to rotate to the bottom position. The detection personnel only need to replace the supporting platform 300 that has been rotated to the top for detection at a constant position, which simplifies the operation process and greatly improves the efficiency of battery diaphragm thickness detection.

[0030] Preferably, the load-bearing opening 110 is a step surface, and the load-bearing platform 300 and the load-bearing opening 110 are detachably connected via a locking workpiece 400. Through the design of the step surface, the inner side of the load-bearing platform 300 is locked and positioned by the load-bearing opening 110, and at the same time, the load-bearing platform 300 and the load-bearing opening 110 can be locked by the locking workpiece 400, thereby further ensuring the stability of the load-bearing platform 300 during the detection process and ensuring the accuracy of the thickness detection result.

[0031] Preferably, the locking workpiece 400 is a locking column, a first locking opening 320 is opened on the side wall of the supporting platform 300, and a second locking opening 111 is opened on the side wall of the supporting opening 110. During the detection process, the supporting platform 300 is placed in a predetermined position, and the locking column is inserted into the first locking opening 320 and the second locking opening 111 to complete the locking and limiting of the supporting platform 300 and the supporting opening 110. The length of the locking column here can be determined according to the size of the supporting platform 300 to ensure the stability of the limiting of the supporting platform 300; at the same time, a thread can be designed between the outer surface of the locking column and the second locking opening 111 to achieve the fixation of the locking column and further ensure the stability of the overall structure.

[0032] An array of negative pressure openings 310 are provided on the surface of the supporting platform 300, and an air nozzle connected to the negative pressure opening 310 is fixed to the side wall of the supporting platform 300. The battery diaphragm is placed flatly on the side with the negative pressure opening, and the air nozzle is connected to the negative pressure device to complete the negative pressure fixation of the battery diaphragm. The above-mentioned fixing method can achieve rapid fixation of the battery diaphragm and is easy to operate. Similarly, the traditional mechanical fixing method can be selected to fix the battery diaphragm to ensure the stability of the battery diaphragm under detection.

[0033] Specifically; the detection mechanism 200 includes a detection arm 210, at the end of which is installed a telescopic element 220, and at the telescopic end of the telescopic element 220 is fixed a thickness detection element 230. The telescopic element 220 can be controlled to be in different positions through the detection arm 210 to quickly detect the thickness of the battery diaphragm at different positions; during the detection process, the detection arm 210 and the telescopic element 220 cooperate with each other to achieve efficient and rapid automatic detection; at the same time, during the overall rotation of the supporting frame 100, the telescopic element 220 is controlled to be in a retracted state to avoid the collision of the thickness detection element 230 with the supporting platform 300, thereby ensuring the normal operation of the overall structure.

[0034] The cross-section of the carrier frame 100 is preferably designed to be a regular polygon, such as a rectangle, a regular hexagon, etc., and the multiple carrier openings 110 are one side of the regular polygon. According to the number of the carrier openings 110, the carrier frame 100 is constantly controlled to rotate at a predetermined angle, so that each carrier platform 300 can be located directly below the detection mechanism 200. There is no need to adjust the deflection angle of the detection mechanism 200, which simplifies the control process and further improves the efficiency of the detection.

[0035] 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.
