[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The embodiment of the present application provides a battery explosion-proof valve detection device, which can calculate the difference between the explosion-proof valve height value and the reference height value. When the difference exceeds the design range, it is determined that the battery explosion-proof valve is unqualified in terms of convexity and concavity, thereby reminding the staff to promptly discover and mark the battery, promptly feedback the convexity and concavity status and make corresponding rapid processing and investigation, so as to avoid appearance problems of batch explosion-proof valves.

[0040] like Figure 1 As shown, an embodiment of the present application provides a battery explosion-proof valve detection device, which may include: a translation component 1, a translation end of the translation component 1 is rotatably connected to an angle adjustment plate 2, and the angle adjustment plate 2 is rotatably connected to a laser emitter 3; the plane where the angle adjustment plate 2 rotates is perpendicular to the plane where the laser emitter 3 rotates.

[0041] Exemplary, specific reference Figure 1 , the translation end of the translation component 1 moves linearly along the Y-axis direction (that is, moves in the front-to-back direction), thereby driving the angle adjustment plate 2 to move linearly along the Y-axis direction, so that the laser emitter 3 on it comes to a suitable position above the battery, wherein the angle adjustment plate 2 can be adjusted with the Y-axis as the rotation axis, and the laser emitter 3 can be adjusted with the X-axis as the rotation axis, that is, the laser emission angle of the laser emitter 3 can be adjusted in the left and right directions by rotating the angle adjustment plate 2, and the laser emission angle of the laser emitter 3 can be adjusted in the front-to-back direction by rotating the laser emitter 3 itself, ultimately ensuring that the laser of the laser emitter 3 can irradiate the explosion-proof valve on the battery top cover, and return to receive the laser, measure the height value between the explosion-proof valve and the laser emitter 3, and use the laser emitter 3 to measure the height value with the battery top cover before measuring the height value of the explosion-proof valve.

[0042] Specifically, by rotating and adjusting the laser emitter 3 itself and the angle adjustment plate 2, the emission angle of the laser can be changed, so that after the laser passes through the PP film (polypropylene film) and is refracted, the receiving end of the laser emitter 3 can receive the completely refracted laser and calculate the height value of the explosion-proof valve. Among them, the laser emitter 3 stores the reference height value pre-measured around the explosion-proof valve in advance, and can calculate the difference between the explosion-proof valve height value and the reference height value. When the difference exceeds the design range, it is determined that the battery explosion-proof valve is unqualified, thereby reminding the staff to promptly discover and mark the battery, promptly feedback the convexity status and make corresponding rapid processing and inspection, so as to avoid appearance problems of batch explosion-proof valves.

The first fastening screw 4 passes through the first waist-shaped hole 2011 and is threadedly connected to the translation end of the translation component 1 to complete the fixing of the angle adjustment plate 2. When the angle adjustment plate 2 needs to be adjusted, the first fastening screw 4 can be loosened first, and then the angle adjustment plate 2 can be rotated to adjust. After adjusting to a suitable angle, the first fastening screw 4 can be tightened to complete the fixing of the angle adjustment plate 2. For details, refer to Figure 3 The second side surface 202 is provided with three second waist-shaped holes 2021, and the through-hole length extension direction of the three second waist-shaped holes 2021 is located in the same circumferential direction. The second fastening screw 5 passes through the second waist-shaped holes 2021 and is threadedly connected with the laser emitter 3 to complete the fixation of the laser emitter 3. When the laser emitter 3 needs to be adjusted, the second fastening screw 5 can be loosened first, and then the laser emitter 3 can be rotated to adjust. After adjusting to a suitable angle, the second fastening screw 5 can be tightened to complete the fixation of the laser emitter 3.

Its first fixed column 6 is fixed to the second rotating block 9. The second rotating block 9 is sleeved on the outer wall of the second fixed column 8 and can rotate with the Z-axis as the rotation axis, so that the position of the laser emitter 3 connected thereto in the XY plane can be adjusted to ensure that the laser emitter 3 is located at a suitable position above the battery.
