[0012] Further, a controller is provided inside the testing machine body, and a display screen and a control switch are provided outside, which is convenient to achieve effective control.

[0013] Furthermore, the frame includes a left support plate and a right support plate. The top of the left support plate and the right support plate jointly support the top beam. The left support plate, the right support plate and the top beam are locked by bolts. The bottom of the left support plate and the right support plate is locked on the upper surface of the testing machine body by bolts, which is convenient for realizing the positioning and installation of the detection component.

[0014] Furthermore, a guiding slide rail is provided on the inner side of the frame, and a slider for matching the guiding slide rail is provided on the detection component, which is convenient for realizing that the detection component can move vertically downward along the frame without deviation.

[0015] Furthermore, a connecting rod is fixedly connected to the top of the moving bracket, and the connecting rod is detachably installed at the bottom of the piston rod.

[0016] Furthermore, the moving bracket is in the shape of "冂". The bottom of the moving bracket is locked with the lower clamping plate. The lower clamping plate and the upper clamping plate are locked by bolts. A gap for clamping the to-be-tested protection plate is provided between the upper clamping plate and the lower clamping plate. Setting the gap is convenient for the installation and placement of the to-be-detected protection plate.

[0017] Furthermore, there are two lower clamping plates, and a clamping convex part is provided on the top of each lower clamping plate; during assembly, the upper clamping plate is pressed on the clamping convex part.

[0018] Furthermore, edge grooves are provided on the outer sides of both sides of the upper clamping plate, and a baffle is provided on the outer side of the lower clamping plate; during assembly, the moving bracket passes through the edge grooves of the upper clamping plate and is installed downward on the limiting groove formed by the clamping convex part of the lower clamping plate and the baffle, which is convenient for better limiting and installing the edges of the moving bracket.

[0019] The second aspect provided by the present utility model is:

[0020] A lithium battery protection plate testing machine system includes a PLC control terminal and at least one of the above-mentioned lithium battery protection plate testing machines. The PLC control terminal is used to control the lithium battery protection plate testing machine to perform tests;

[0021] and when there are multiple lithium battery protection plate testing machines, they are tested in turn;

[0022] The to-be-detected protection plate is a whole plate or a whole plate assembled by several small plates.

[0023] Furthermore, the lithium battery protection plate testing machine system further includes an actuator and an external touch screen, so as to realize the automatic testing work of the lithium battery protection plate through this system.

[0026] (3) Beneficial effects

[0027] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model sets an induction plate on the upper surface of the testing machine body and sets several test points on the induction plate. By switching the connection between each test point and the protection board to be tested, the model tests each small board of a whole board. The pressure condition between the test point and the protection board to be tested determines whether the protection board is defective. The model tests whether the protection board can work normally under various protection conditions and obtains the results. By setting a detection component above the induction plate to drive the protection board to be tested downward, the model simulates the working state of the battery under different pressures and tests whether the protection board can work normally under various pressure conditions. The model tests the pressure resistance performance of the lithium battery protection board, ensuring that it will not be damaged or fail under extreme conditions, and records the results effectively. This reduces the errors and inefficiencies of manual measurement, improves intelligent processing operations, and proposes a lithium battery protection board testing machine system that provides a scheme to test six boards at a time in turn, greatly improving testing efficiency. It can use fewer testing machines to test a protection board composed of multiple small boards. With a simple structure and few moving parts, the test is accurate and intuitive, and the test results, whether good or bad, can be displayed on the screen. Attached Figure Description

[0035] The present invention will be further described below with reference to the embodiments.

[0036] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "vertical", "horizontal", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] like Figure 1-3 As shown, this embodiment provides a lithium battery protection board testing machine, including a testing machine body 1. The testing machine body 1 includes an induction plate 11 disposed at its top center for testing. The induction plate 11 has several test points. To facilitate the limiting of the induction plate 11, this solution proposes that the edge of the induction plate 11 be provided with a limiting block 12. The limiting block 12 is L-shaped. The induction plate 11 is electrically connected to the testing machine body 1. A frame 2 is mounted on the outside of the induction plate 11. A detection component 3 for testing the protection board 4 to be tested is provided in the middle of the frame 2. See the appendix for details. Figure 1 The frame 2 includes a left support plate and a right support plate. The tops of the left and right support plates together support the top beam. The left and right support plates and the top beam are locked together by bolts. The bottoms of the left and right support plates are locked to the upper surface of the test machine body 1 by bolts.

[0038] The detection component 3 includes a hydraulic cylinder 31, with a piston rod 32 extending downwards from the hydraulic cylinder 31. A movable bracket 34 is mounted below the piston rod 32. The bottom of the movable bracket 34 is provided with an upper clamping plate 36 and a lower clamping plate 37 for clamping the test protection plate 4. A limiting step 371 is provided on the inward side of the lower clamping plate 37. To improve the movement of the movable bracket 34 along a predetermined direction and to make the sliding smoother, a guide rail 21 is provided on the inward side of the frame 2. The detection component 3 is provided with a slider 35 for matching the guide rail 21. A connecting rod 33 is fixedly connected to the top of the movable bracket 34. The connecting rod 33 is detachably mounted on the bottom of the piston rod 32.

[0039] In order to better treat the clamping effect of the test protection board 4, the moving bracket 34 is in the shape of "冂". The bottom of the moving bracket 34 is locked with the lower clamping plate 37. The lower clamping plate 37 and the upper clamping plate 36 are locked by bolts. There is a gap for inserting the test protection board 4 between the upper clamping plate 36 and the lower clamping plate 37. There are two lower clamping plates 37, and a clamping convex part is provided at the top of each lower clamping plate 37. During assembly, the upper clamping plate 36 is pressed on the clamping convex part. In order to realize the limit of the left support plate and the right support plate, edge grooves are provided on both sides of the upper clamping plate 36 outward, and a baffle 372 is provided on the outside of the lower clamping plate 37. During assembly, the moving bracket 34 passes through the edge groove of the upper clamping plate 36 and is installed downward on the limit groove formed by the clamping convex part of the lower clamping plate 37 and the baffle 372.

[0040] In order to effectively detect and display defective boards, a controller is provided inside the test machine body 1, and a display screen 13 and a control switch 14 are provided outside, which is convenient for test operation and classification of defective products.

[0041] When the utility model is in use, the test protection board 4 to be tested is installed between the upper clamping plate 36 and the lower clamping plate 37 of the moving bracket 34. The hydraulic cylinder 31 is used to drive the piston rod 32 to descend, and the connecting rod 33 also descends, driving the moving bracket 34 and the test protection board 4 to descend, and then contacting the induction plate 11 of the test machine body 1. Whether the parameters of each detection point of the test protection board 4 are qualified is sensed through the test points on the induction plate 11. When the hydraulic cylinder 31 converts the pressure to the limit position of the protection board 4, check whether the parameters are qualified, and then judge whether it is a defective board, reducing the complexity of manual detection. At the same time, a lithium battery protection board testing machine system is also proposed in this solution, including a PLC control terminal and the above-mentioned lithium battery protection board testing machine. The PLC control terminal is used to control the lithium battery protection board testing machine to perform tests; and when there are multiple lithium battery protection board testing machines, they are tested in turn. Specifically, in practice, we will form an integrated automated testing system with six lithium battery protection board testing machines, an actuator (existing), a PLC control terminal (existing), and an external touch screen (existing). Therefore, six test protection boards 4 can be tested each time during use, and through setting programs, they can be tested in turn, and at most sixty protection boards can be tested each time. After the test is completed, we can also view the positions of the defective boards on the external touch screen and then screen them out. It should be noted that the main improvement in this solution is the lithium battery protection board testing machine part, and other components in the system can be arranged and combined according to the prior art.

[0042] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
