Description

Technical Field

[0001] This utility model relates to the field of vacuum technology, and in particular to a vacuum potting fixture for battery production. Background Technology

[0002] In some specialized equipment, such as oil centralizers, the battery packs used for power supply need to be connected in series during assembly, then placed inside a fiberglass tube, and finally encapsulated with glue. During the glue encapsulation process, a vacuum needs to be simultaneously applied to the inside of the fiberglass tube.

[0003] During the process of vacuuming and filling the fiberglass tube with adhesive, a vacuum machine is generally used to extract air. A tooling is fixed and sealed to the outer wall of the corresponding air extraction hole of the fiberglass tube, and then connected to the vacuum machine through a pipe.

[0004] However, the existing vacuum potting fixtures for fiberglass tubes have a complex structure, which makes installation complicated when sealing the connection with the fiberglass tubes. Over long periods of operation, this can easily lead to a decrease in sealing performance. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology, such as complex structure, complicated installation when sealing with glass fiber tube, and easy degradation of sealing performance during long-term operation. Therefore, a vacuum potting tool for battery production is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vacuum potting fixture for battery production includes two sets of clamping blocks, each set of clamping blocks having a fixing groove on its outer wall, and one set of clamping blocks having a negative pressure port; a sealing gasket is provided between the two sets of clamping blocks; and a sealing ring is also included, which is fitted onto a fiberglass tube and abuts against the inner wall of the clamping block.

[0008] Preferably, the inner walls of both sets of clamping blocks are provided with a second sealing groove, and the sealing ring is located in the second sealing groove.

[0009] Preferably, both the second sealing groove and the sealing ring are designed in two sets.

[0010] Preferably, the mating surfaces of the two sets of clamping blocks are provided with a first sealing groove, and the sealing gasket is located in the first sealing groove.

[0011] Preferably, the inner walls of the two sets of clamping blocks are further provided with redundant grooves, which are located between the two sets of second sealing grooves.

[0012] Preferably, the fixing groove is designed in two sets.

[0013] Compared with the prior art, this utility model provides a vacuum potting fixture for battery production, which has the following advantages:

[0014] 1. The vacuum potting fixture used in battery production consists of only two sets of clamping blocks, followed by sealing gaskets and sealing rings for sealing. The structure is simple, and it can be directly fixed with clamps when sealing with fiberglass tubes. Installation is also convenient. Due to the small number of parts, the probability of failure is greatly reduced. It is not easy for the sealing performance to deteriorate during long-term operation. Even if it does deteriorate, the sealing gaskets and sealing rings can be replaced directly, which is convenient and quick. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0022] Example:

[0023] like Figures 1-4A vacuum potting fixture for battery production includes two sets of clamping blocks 2, which are clamped to the outer wall of a fiberglass tube 1. Each set of clamping blocks 2 has a fixing groove 201 on its outer wall. When the two sets of clamping blocks 2 are clamped to the outer wall of the fiberglass tube 1, the fixing grooves 201 on the two clamping blocks 2 fit together to form a circular groove. One set of clamping blocks 2 has a negative pressure port 202. A vacuum machine is connected to the negative pressure port 202 through a pipe. When the two sets of clamping blocks 2 are clamped to the outer wall of the fiberglass tube 1, the negative pressure port 202 is connected to the air extraction hole 101 on the fiberglass tube 1.

[0024] like Figure 2 A sealing gasket 4 is provided between the two sets of clamping blocks 2. When the clamping block 2 is clamped to the outer wall of the fiberglass tube 1, the sealing gasket 4 is clamped between the two sets of clamping blocks 2. The sealing gasket 4 is designed in two sets, with one set on each side of the contact surface on both sides of the clamping block 2.

[0025] The vacuum potting fixture for battery production disclosed in this embodiment also includes a sealing ring 401. The sealing ring 401 is circular and is fitted onto the fiberglass tube 1. The sealing ring 401 is tightly fitted to the outer wall of the fiberglass tube 1. When the clamping block 2 is clamped onto the outer wall of the fiberglass tube 1, the sealing ring 401 abuts against the inner wall of the clamping block 2.

[0026] Both the sealing gasket 4 and the sealing ring 401 are made of rubber.

[0027] When vacuuming the fiberglass tube 1, first, the sealing ring 401 is placed on the outer wall of the fiberglass tube 1, and then two sets of clamping blocks 2 are clamped onto the outer wall of the fiberglass tube 1. At the same time, two sets of sealing gaskets 4 are placed between the two sets of clamping blocks 2, and then fixed by clamps. The clamps are clamped into the fixing groove 201. Finally, the vacuum machine is connected to the negative pressure port 202 through the pipe, and the fiberglass tube 1 is vacuumed by the vacuum machine to facilitate battery assembly and glue filling.

[0028] When the clamps fix the two sets of clamping blocks 2, the two sets of clamping blocks 2 simultaneously squeeze the sealing gasket 4 and the sealing ring 401 to achieve a sealing effect and prevent air leakage.

[0029] During assembly, there are only two sets of clamping blocks 2, and then the sealing gasket 4 and sealing ring 401 that play a sealing role. The structure is simple. When sealing and connecting with the fiberglass tube 1, it can be fixed directly by clamps. The installation is also convenient. Since there are few parts, the probability of failure is greatly reduced. It is not easy for the sealing performance to decline during long-term operation. Even if it does decline, the sealing gasket 4 and sealing ring 401 can be replaced directly, which is convenient and quick.

[0030] like Figure 3 and Figure 4Both sets of clamping blocks 2 have a second sealing groove 301 on their inner walls, and a sealing ring 401 is located in the second sealing groove 301; both the second sealing groove 301 and the sealing ring 401 are designed in two sets; during assembly, the two sets of sealing rings 401 are located on the upper and lower sides of the air extraction hole 101 respectively.

[0031] During assembly, the sealing ring 401 is engaged in the corresponding second sealing groove 301, increasing the contact area between the sealing ring 401 and the inner wall of the clamping block 2, thereby improving the sealing effect.

[0032] like Figure 3 Both sets of clamping blocks 2 have a first sealing groove 3 on their mating surfaces, and the sealing gasket 4 is located in the first sealing groove 3.

[0033] The first sealing groove 3 is also in two sets, with one set on each side of the mating surface of the clamping block 2. During assembly, the sealing gasket 4 is clamped in the corresponding first sealing groove 3. After the installation is completed, the two sets of clamping blocks 2 can squeeze the sealing gasket 4 while also achieving mutual mating of the two sets of clamping blocks 2, thus improving the overall integrity after assembly.

[0034] like Figure 3 The inner walls of the two sets of clamping blocks 2 are also provided with redundant grooves 5, which are located between the two sets of second sealing grooves 301.

[0035] The negative pressure port 202 is connected to the redundant groove 5; the second sealing groove 301 surrounds the inner wall of the clamping block 2. After assembly, the redundant groove 5 is connected to the air extraction port 101.

[0036] By using the redundant slot 5 design, even if the negative pressure port 202 and the air extraction port 101 are not aligned due to errors during the assembly process, vacuuming can still be achieved through the connection of the redundant slot 5, thus improving the redundancy design.

[0037] like Figures 1-4 The fixing groove 201 is designed in two sets. The two sets of fixing grooves 201 are arranged horizontally on the side wall of the clamping block 2, and are located on the upper and lower sides of the negative pressure port 202 respectively.

[0038] Each set of fixing slots 201 is fixed by a clamp.

[0039] The clamping block 2 is fixed by two clamps, which makes the force more even and improves the stability of long-term operation.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
