Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0032] Please refer to Figures 1-7 , the present utility model provides a technical solution: a lithium battery bulging detection device, provided with a detection frame 1 that is convenient for positioning and assembly, and the upper surface of the detection frame 1 is rotatably connected with a conveyor belt 2, and a lithium battery body 3 is centrally conveyed on the upper surface of the conveyor belt 2;

[0034] The detection frame 1 and the infrared laser detector 4 form an internal nested structure, and the detection frame 1 and the infrared laser detector 4 form a threaded adjustment limiting sliding structure through the threaded rod 5 and the embedding kit 6, and the embedding kit 6 and the detection frame 1 form a limiting snap-fitting structure, and at the same time, the infrared laser detector 4 is symmetrically arranged about the middle section of the inner surface of the detection frame 1.

[0035] During use, the detection rack 1 is fixed at the position where the lithium battery body 3 is produced, and the completed lithium battery body 3 is stably moved onto the conveyor belt 2 assembled on the detection rack 1, and the lithium battery body 3 is centered for conveying. During the conveying process, the height of the lithium battery body 3 passing through can be detected by the infrared laser detector 4 assembled on the detection rack 1. According to the production height range of the lithium battery body 3, the motor on the upper side of the inlay kit 6 assembled and clamped by the detection rack 1 is controlled to operate, the threaded rod 5 is controlled to rotate for positioning, and the infrared laser detector 4 is driven to adjust the height accordingly, so as to adapt to the height required during the production of the lithium battery body 3, and effectively detect the height of the lithium battery body 3 through non-contact physical means, avoiding the situation of the lithium battery body 3 bulging;

[0036] The bevel gear set 7 is rotatably connected to the conveyor belt assembled on the detection rack 1. One set of gears in the bevel gear set 7 is threadedly connected to a lead screw 8, and this gear is positioned and rotated on the inner surface of the detection rack 1. The lower surface of the lead screw 8 is provided with a fixing plate 9. At the same time, the lower surface of the fixing plate 9 is connected to a telescopic assembly 10, and the lower surface of the telescopic assembly 10 is connected to a moving plate 11. An extrusion spring 12 is assembled between the moving plate 11 and the fixing plate 9, and the extrusion spring 12 is nested on the inner surface of the telescopic assembly 10;

[0037] The spur gear 13 is rotatably connected to the middle section of the inner surface of the moving plate 11. The outer surface of the spur gear 13 is meshed with a rack 14, and the rack 14 is limited and slidably connected to the inner surface of the moving plate 11. The lower surface of the rack 14 is provided with a detection component 15. At the same time, a limiting strip 16 is installed on the upper surface of the detection component 15, and the limiting strip 16 is limited and slidably arranged on the inner surface of the moving plate 11.

[0038] The bevel gear set 7 and the detection rack 1 form a linkage rotation structure through the conveyor belt. One set of gears in the bevel gear set 7 and the detection rack 1 form a positioning rotation structure. One set of gears in the bevel gear set 7 and the lead screw 8 form a threaded structure. At the same time, the lead screw 8 and the fixing plate 9 form an integrated structure. The fixing plate 9 and the moving plate 11 form an elastic telescopic structure through the telescopic assembly 10 and the extrusion spring 12. At the same time, the fixing plate 9 and the moving plate 11 and the detection rack 1 form a limiting sliding structure.

[0039] The moving plate 11 and the rack 14 form a meshing sliding structure through the spur gear 13. The rack 14 is arranged at equal angles about the central axis of the inner surface of the spur gear 13. The rack 14 and the detection component 15 and the limiting strip 16 form an integrated structure. At the same time, the limiting strip 16 and the moving plate 11 form a supporting sliding structure.

[0040] The detection head 17 is nested and connected to the inner surface of the detection component 15, and the locking part 18 is snap-connected to the outer surface of the detection head 17, and the locking part 18 is threadedly connected to the inner surface of the detection component 15.

[0041] The detection component 15 and the detection head 17 form a built-in nested structure, and the detection head 17 is symmetrically arranged about the middle section of the outer surface of the detection component 15. Moreover, the detection component 15 and the detection head 17 form a limit clamping structure through the locking part 18, and the outer surface shape of the locking part 18 is an arc structure.

[0042] When the conveyor belt 2 on the detection rack 1 stably conveys the lithium battery body 3, when physically detecting the height of the lithium battery body 3, the first detection can be effectively formed. Thus, according to the motor assembled on the detection rack 1 later, the conveyor belt can be effectively driven to rotate. Then, the rotation of the conical gear set 7 is adjusted by the shaft rotation, and a set of gears in the conical gear set 7 is stably nested in the detection rack 1 to form a positioning rotation. Moreover, the threaded rotation between this gear and the lead screw 8 is controlled, and the fixing plate 9 on which the lead screw 8 is installed is controlled to move up and down. Also, the moving plate 11 connected to the telescopic assembly 10 assembled under the fixing plate 9 is controlled to move synchronously. When the detection head 17 assembled under the moving plate 11 contacts the positive and negative electrodes of the lithium battery body 3, the elastic telescopic property between the fixing plate 9 and the moving plate 11 is generated by the compression spring 12 outside the telescopic assembly 10, which improves the stability of the contact between the detection head 17 and the positive and negative electrodes of the lithium battery body 3, and effectively detects the voltage and resistance of the lithium battery body 3 to identify whether there is a bulging situation in the lithium battery body 3. Moreover, when the fixing plate 9 and the moving plate 11 move in position, they can form a limit sliding within the detection rack 1 to prevent deflection. In addition, the motor on the moving plate 11 drives the straight-tooth gear 13 to control the position adjustment of the rack 14 arranged at equal angles. Thus, the distance between the detection heads 17 under the detection component 15 installed on the rack 14 is controlled. Also, the limiting strip 16 installed in cooperation with the detection component 15 forms a limit sliding on the inner surface of the moving plate 11, thus preventing the situation of falling. Moreover, the stability of the detection head 17 during use is controlled, and the detection head 17 is stably nested and assembled on the inner surface of the detection component 15. Furthermore, the locking part 18 with threaded rotation is used to squeeze the detection head 17, which improves the stability of the assembly of the detection head 17 and prevents it from falling off. In addition, the detection heads 17 are symmetrically distributed on the left and right sides of the outer surface of the detection component 15, and thus the minimum distance and the maximum distance can be used, improving the convenience of detection.
