DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example:

[0038] like Figure 1-8 As shown,

[0039] In order to reduce the manual handling and installation of the clamping mechanism during the production of the explosion-proof battery 18, a conveying roller assembly 19 is used to transport the explosion-proof battery 18. The conveying roller assembly 19 is arranged on the lower side of the bottom plate 10, and the explosion-proof battery 18 can be transported to the lower side of the bottom plate 10 through the conveying roller assembly 19. At the same time, the cylinder 2 is extended to drive the bracket 3 and other mechanisms to complete the clamping and inflation of the explosion-proof battery 18.

[0040] In order to facilitate installation, debugging and maintenance, the top of the cylinder 2 is fixed to the cylinder seat 1 by bolt connection, and the lower end of the cylinder 2 is also fixedly connected to the bracket 3 by bolt connection. The bracket 3 is an inverted U-shaped structure, and the base plate 10 is fixed to the bottom of the bracket 3.

[0041] The bottom plate 10 is provided with through holes for an injection pipe hole 26, a pressure gauge hole 27, a positive electrode hole 28, and a negative electrode hole 29, which are used for the injection pipe, the pressure gauge, the positive electrode, and the negative electrode to pass through, respectively.

[0042] An electromagnet 4 is fixed in the middle of the upper part of the base plate 10, and a first slider 5, a second slider 7, a third slider 21, and a fourth slider 11 are fixed at four positions on the upper part of the base plate 10 respectively. A movable first slide rail 15, a second slide rail 13, a third slide rail 20, and a fourth slide rail 23 are arranged inside the first slider 5, the second slider 7, the third slider 21, and the fourth slider 11 respectively.

[0043] The first armature 6 and the first clamping plate 14 are fixed at both ends of the first slide rail 15, the second armature 8 and the second clamping plate 12 are fixed at both ends of the second slide rail 13, the third armature 30 and the third clamping plate 22 are fixed at both ends of the third slide rail 20, and the fourth armature 31 and the fourth clamping plate 17 are fixed at both ends of the fourth slide rail 23.

[0044] Springs are provided on the first slide rail 15 between the first slider 5 and the first clamp plate 14, on the second slide rail 13 between the second slider 7 and the second clamp plate 12, on the third slide rail 20 between the third slide rail 20 and the third slider 21, and on the fourth slide rail 23 between the fourth slider 11 and the fourth clamp plate 17. The spring 9 is used to provide a reset elastic force for each slider.

[0045] The first clamping head 16 is provided on the first clamping plate 14, the second clamping plate 12, and the third clamping plate 22, and the step clamping head 25 is provided on the fourth clamping plate 17, and the front end of the step clamping head 25 is a deflation needle 24. Since the shell of the explosion-proof battery 18 is a sealed structure, the deflation needle 24 can open the deflation valve of the sealed explosion-proof battery 18, so that the original air can be released when the insulating gas is filled inside the explosion-proof battery 18 through the injection pipe hole 26, so that the interior of the explosion-proof battery 18 can obtain high-purity insulating gas; at the same time, the barometer provided on the explosion-proof battery 18 can be observed through the barometer hole 27 to determine whether the pressure of the insulating gas filling meets the requirements.

[0046] like Fig. 9 , 10 As shown in Figures 1 and 11, the electromagnet 4 is an I-shaped structure when viewed from above, and its core surface 1 32, core surface 2 33, core surface 34, and core surface 4 35 correspond to the first armature 6, the second armature 8, the third armature 30, and the fourth armature 31, respectively. The core surface 1 32, the core surface 2 33, and the first armature 6 and the second armature 8 are of the same symmetrical distribution structure. The ratio of the distance between the core surface 3 34 and the core surface 4 35 on the electromagnet 4 and the center of the coil winding of the electromagnet 3 is 2:3, that is, a:b=2:3. Similarly, the core area or the air gap distance between the core surface and the armature can be controlled to realize the control of the order of the corresponding armature actions.

[0047] Because the area of ​​the core surface 1 32, the core surface 2 33 and the first armature 6 and the second armature 8 is larger; the area of ​​the core surface 34, the core surface 4 35 and the third armature 30 and the fourth armature 31 is smaller, after the electromagnet 4 is energized, the first armature 6 and the second armature 8 attract each other faster, so that the first slide rail 15 connected to the first armature 6, the first clamping head 16 on the first clamping plate 14 and the second slide rail 13 connected to the second armature 8, the first clamping head 16 on the second clamping plate 12 can move to the middle first, clamping and fixing the explosion-proof battery 18 in the middle position of the device.

[0048] Since the ratio of the distances between the core surface 34 and the core surface 4 35 on the electromagnet 4 and the center of the coil winding of the electromagnet 3 is a:b=2:3, the third armature 30 moves in the second step, and the fourth armature 31 moves last, so that the fourth slide rail 23, the fourth clamping plate 17, the stepped clamping head 25, and the deflation needle 24 connected to the fourth armature 31 can maintain the position of the symmetrical center and accurately penetrate into the deflation valve of the explosion-proof battery 18.

[0049] That is, it realizes Fig. 9 The action process of (A) clamping at both ends → (B) positioning at the rear → (C) pushing in the deflation needle.

[0050] Specific implementation process:

[0051] ①. The explosion-proof battery 18 is transported to the lower station of the bottom plate 10 through the conveying roller assembly 19, and the transportation is kept suspended.

[0052] ②. Start the cylinder 2, which pushes the bracket 3 and the bottom plate 10 downward to the specified position.

[0053] ③. The electromagnet 4 is energized. The first armature 6 and the second armature 8 are preferentially attracted to each other, so that the first slide rail 15 connected to the first armature 6, the first clamping head 16 on the first clamping plate 14 and the second slide rail 13 connected to the second armature 8, the first clamping head 16 on the second clamping plate 12 move toward the middle first, clamp the two corresponding sides of the explosion-proof battery 18, and fix them in the middle position of the device; the third armature 30 moves in the second step to fix the third side of the explosion-proof battery 18; the fourth armature 31 moves last to fix the fourth side. In this way, the fourth slide rail 23, the fourth clamping plate 17, the stepped clamping head 25, and the deflation needle 24 connected to the fourth armature 31 can maintain the position of the symmetrical center and accurately penetrate into the deflation valve of the explosion-proof battery 18.

[0054] That is, it realizes Fig. 9 The action process of (A) → (B) → (C) in the figure.

[0055] ④. Inert gas and related substances, such as sulfur hexafluoride, are filled into the explosion-proof battery 18 through the injection tube hole 26; the gas pressure of the inert gas and other substances filled can be observed on the barometer on the explosion-proof battery 18 through the barometer hole 27. For the convenience of operation (or ergonomics), the injection tube hole 26 is set on the right hand side of the operator, and the barometer hole 27 is set on the left hand side of the operator. After the inflation meets the relevant requirements, the relevant devices are removed.

[0056] ⑤. The electromagnet 4 is powered off. The first armature 6, the second armature 8, the third armature 30, and the fourth armature 31 return to their initial positions under the elastic force of the spring 9.

[0057] ⑥, start the cylinder 2 again, and the cylinder 2 pushes the bracket 3 and the bottom plate 10 upward to the initial position;

[0058] ⑦. Start the conveying roller assembly 19 again to transport the explosion-proof battery 18 to the next station.

[0059] The above design purpose is achieved.
