[0002] The sealing of the explosion-proof valve, pole and other components of the battery cover has a great impact on the safety of battery use. Therefore, the battery cover needs to be tested for sealing during the production process. Currently, helium testing devices are generally used on the market to test the sealing of the battery top cover.

[0003] As attached Figure 1 As shown, the existing helium detection mechanism is mainly composed of a fixture, a driving member and a back plate. A cavity for placing the battery is provided inside the fixture, and holes corresponding to the explosion-proof valve and poles of the battery cover are provided on the bottom wall of the cavity, and sealing rings are provided around the holes to ensure airtightness; the driving member is used to drive the back plate to close the cavity, and then helium is injected into the cavity through the air pressure holes on the back plate to perform pressure detection.

[0004] However, in actual use, it was found that due to the influence of air pressure, after the helium inspection, the battery cover may be firmly bonded to the cavity by the sealing ring. At this time, the entire machine needs to be stopped and tools need to be used to pry out the battery cover, which brings great inconvenience to production operations. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See attached Figure 1 -Attached Figure 8 , an auxiliary demoulding mechanism for helium inspection, comprising a jig 1 and a demoulding portion 3; a cavity 10 for placing a battery cover 2 is provided inside the jig 1, a column groove 101, a valve groove 102 and a movable hole 103 are provided on the bottom wall of the cavity 10, the column groove 101 corresponds to the pole clamped with the battery cover 2, the valve groove 102 corresponds to the explosion-proof valve clamped with the battery cover 2, and a sealing ring 10m for fitting the battery cover 2 is installed at the edge of the column groove 101 and the valve groove 102; the demoulding portion 3 comprises a top column 31 and an elastic member 32, the top column 31 can be slidably installed in the movable hole 103, and the upper end of the top column 31 extends into the cavity 10; the elastic member 32 is installed in the movable hole 103, and the two ends of the elastic member 32 respectively abut the bottom wall of the movable hole 103 and the lower end of the top column 31.

[0034] Specifically, for ease of understanding, the present invention needs to explain the working principle in conjunction with the pressing device 6, as shown in the attached Figure 1 As shown, the pressing device 6 belongs to the prior art, and mainly includes a pressing tool 61 and a driving cylinder 62 .

[0035] Under normal circumstances, the pressing device 6 is located above the cavity 10, the elastic member 32 is in the initial state, and the upper end of the top column 31 is located in the cavity 10;

[0036] During the helium inspection, the battery cover 2 is placed in the cavity 10 and abuts against the top column 31, and then the press 61 is driven downward by the driving cylinder 62 to squeeze the battery cover 2 so as to squeeze and fix the battery cover 2 in the cavity 10. During this process, the battery cover 2 drives the top column 31 to completely enter the movable hole 103 to avoid the position, and the elastic member 32 is compressed to store energy. After the battery cover 2 is completely fixed, helium is injected into the cavity 10 through the air pressure hole 610 on the press 61 to perform the helium inspection.

[0037] After the helium inspection is completed, the press 61 moves up and separates from the battery cover 2, and the elastic member 32 releases energy to recover and drives the ejector 31 to enter the cavity 10, so as to lift the battery cover 2 from the cavity 10, so that the battery cover 2 is separated from the sealing ring 10m and automatically demolded. At this time, the battery that has completed the helium inspection can be taken and transferred to the next process by a robot (not shown) or manually.

[0038] In summary, the utility model sets a movable hole 103 in the cavity 10 of the fixture 1 for the movement of the top column 31 and the elastic member 32, so that the top column 31 can be squeezed into the movable hole 103, thereby avoiding the top column 31 and the battery cover 2 from being damaged by a rigid collision. At the same time, since the elastic member 32 has a recovery tendency, it can drive the top column 31 to reset after the helium inspection is completed, so that the top column 31 lifts the battery cover 2 in the cavity 10, ensuring that the battery cover 2 is separated from the sealing ring 10m, realizing automatic demolding, and improving production convenience.

[0039] See attached Fig. 9 The elastic member 32 can be of various types, such as a spring, a rubber column, etc.

[0040] Among them, the spring is cheap and the rubber column is highly wear-resistant, both of which have their own advantages. Users can choose according to their needs, and this is not limited in the utility model.

[0041] See attached Fig. 9 -Attached Fig.10 The utility model also includes a fixing seat 4, a fixing groove 104 is provided on the bottom wall of the cavity 10, and a notch 105 connected to the movable hole 103 is provided on the groove wall of the fixing groove 104; a bayonet 310 is provided at the upper end of the top column 31; the fixing seat 4 is installed in the fixing groove 104 to block the notch 105 and abut against the side wall of the bayonet 310.

[0042] Specifically, during installation, the elastic member 32 and the top column 31 are first placed in the movable hole 103 in sequence, and then the fixing seat 4 is installed in the fixing groove 104, and the fixing seat 4 is made to abut against the side wall of the bayonet 310; and with the cooperation of the fixing seat 4 and the bayonet 310, the rotation of the top column 31 can be restricted, and the top column 31 can be prevented from being separated from the movable hole 103, thereby improving the sliding stability and installation stability of the top column 31.

[0043] During disassembly, the fixing seat 4 is taken out from the fixing groove 104 to release the restriction on the top column 31 , so that the user can normally take out the top column 31 and the elastic member 32 for maintenance or replacement.

[0044] See attached Figure 6 -Attached Fig.12In actual use, with multiple squeezing of different battery cover plates 2, the elastic member 32 will gradually lose its elasticity, resulting in its recovery ability becoming smaller and unable to drive the top column 31 to normally lift the battery cover plate 2; in this case, either a new elastic member is replaced, or the elastic potential energy of the elastic member 32 is increased by squeezing and shortening the length of the elastic member 32; in order to make the best use of it and facilitate the user to adjust the elastic force of the elastic member 32, the utility model also includes an adjusting part 5, the adjusting part 5 includes a butt plate 51 and a driving member 52, the butt plate 51 can be slidably installed in the movable hole 103, and the end of the elastic member 32 away from the top column 31 abuts the butt plate 51; the driving member 52 is installed on the fixture 1 and is drivingly connected to the butt plate 51 to drive the butt plate 51 to move along the movable hole 103, thereby squeezing the elastic member 32 to adjust the elastic force.

[0045] Specifically, when the elastic force of the elastic member 32 is too small, the driving member 52 drives the abutment plate 51 to move along the direction of the movable hole 103 and approach the top column 31. Since the upper end of the elastic member 32 is restricted by the fixing seat 4, the elastic member 32 will be squeezed and shortened by the abutment plate 51 to increase the elastic potential energy, thereby increasing the relative elastic force of the elastic member 32, ensuring that the elastic member 32 can normally lift the battery cover 2 out of the sealing ring 10m.

[0046] See attached Figure 6 -Attached Fig.12 There are various types of driving members 52, for example, motors and cylinders with moving strokes can be used. However, in order to control costs and improve structural stability, in the utility model, a connected guide hole 106 is provided on the side of the movable hole 103, and a guide bar 511 that slides with the guide hole 106 is provided on the abutment plate 51, and a sleeve 512 is provided on the guide bar 511; the driving member 52 is a bolt, which is rotatably mounted on the fixture 1, and the threaded end of the bolt extends into the guide hole 106 and is threadedly connected to the sleeve 512.

[0047] Specifically, since the guide hole 106 can limit the rotation of the guide bar 511 , rotating the bolt can drive the sleeve 512 to move, thereby driving the abutment plate 51 to move along the movable hole 103 to squeeze or loosen the elastic member 32 .

[0048] See attached Figure 6 -Attached Fig.12 In order to facilitate the disassembly and assembly of the support plate 51, in the utility model, the guide hole 106 is located below the fixing groove 104 and connected to the notch 105 to facilitate the removal and placement of the support plate 51; the bolt is rotatably mounted on the fixing seat 4, and the threaded end of the bolt sequentially penetrates the fixing seat 4 and the notch 105 to the guide hole 106, and is threadedly connected to the sleeve 512.

[0049] Specifically, during installation, align the support plate 51 with the movable hole 103, align the guide bar 511 with the guide hole 106, and then place the support plate 51 and the guide bar 511 as a whole in the movable hole 103 and the guide hole 106 through the notch 105, then put the elastic member 32 and the top column 31 into the movable hole 103 in turn, and install the fixing seat 4 into the fixing groove 104, and finally install the bolt on the fixing seat 4 and threadedly connect it with the sleeve 512 in the guide hole 106; similarly, during disassembly, first unscrew the bolt, then take out the fixing seat 4, and then take out the top column 31, the elastic member 32 and the support plate 51 in turn.

[0050] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
