Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery box processing technology, and in particular to a battery box cover foam sealant application fixture. Background Technology
[0002] The battery box cover adhesive applicator is an auxiliary tool specifically designed for applying foam sealant to the battery box cover. Its main function is to ensure that the foam sealant is applied evenly and accurately to the designated locations on the battery box cover, thereby improving the sealing performance of the battery box, preventing leakage and moisture damage during battery use, and ensuring the safety and stability of the battery.
[0003] Most battery box top covers are rectangular in design. When applying adhesive, they need to be flipped over and placed on a workbench, then clamped and fixed before the adhesive is applied. However, the top of the top cover is usually designed with a specific shape due to product requirements, which makes it difficult to keep the top cover level on the workbench after flipping. If such a difficult-to-level top cover is fixed directly, it will be in a tilted state. Applying sealant in a tilted state will result in uneven application of sealant. This unevenness will seriously affect the sealing effect of the battery box top cover, thereby reducing the sealing performance of the battery box. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a battery box cover foam sealant applicator, comprising a processing table and a cover plate, wherein the cover plate is located on the upper side of the processing table, a horizontal slot is provided on the top of the processing table, a drive motor is fixedly installed on the right side of the processing table, the left end of the drive motor penetrates the inner wall of the right side of the horizontal slot and extends into the horizontal slot, a bidirectional screw is fixedly installed on the output end of the drive motor extending into the horizontal slot, and a movable locking block is threadedly connected to the bidirectional screw, the movable locking block being slidably engaged with the horizontal slot;
[0005] There are two movable blocks, and multiple clamping mechanisms for lifting the upper cover plate and keeping it horizontal are fixedly installed on the top of the two movable blocks in a rectangular arrangement. The clamping mechanisms are movably engaged with the upper cover plate.
[0006] As an improvement to the above technical solution, the clamping mechanism includes a translation main board, a horizontal main block, a pressing block, and a support spring. The translation main board is fixedly installed on the top of the moving block. The horizontal main blocks are symmetrically fixedly installed at both ends of the top of the translation main board. A locking slot is provided on the left side of the horizontal main block near the middle. The top inner wall of the locking slot is rounded close to the left side. An arc angle is provided at the angle between the left side of the horizontal main block and the bottom inner wall of the locking slot. A vertical slot is provided on the top inner wall of the locking slot. The pressing block is slidably engaged in the vertical slot. The support spring is fixedly installed on the top inner wall of the vertical slot. The bottom end of the support spring is fixedly installed with the top of the pressing block. The upper cover is movably engaged between the locking slot and the pressing block. The length of the horizontal main block near the top is less than the length of the horizontal main block near the bottom.
[0007] As an improvement to the above technical solution, a stabilizing block is fixedly installed at both ends of the bottom of the translation motherboard, and the bottom of the stabilizing block is in contact with the top of the processing table.
[0008] As an improvement to the above technical solution, multiple friction strips are fixedly installed at the bottom of the pressing block in a linear and uniform arrangement.
[0009] As an improvement to the above technical solution, the bottom left side of the pressing block is designed with rounded corners.
[0010] The beneficial effects of this utility model are as follows: The top cover is flipped over and placed at the center of the top of the processing table.

The edges of the top cover are clamped synchronously by multiple clamping mechanisms, and the top cover is squeezed and moved upward to a certain height, so that the top cover is kept horizontal in the air. At the same time, the top cover is clamped and fixed by various methods such as squeezing and pressing after being suspended, so that foamed sealant is applied to the top cover in a horizontal state, thereby ensuring that the sealant is applied evenly. This even application will significantly improve the sealing effect of the battery box top cover, thereby enhancing the sealing performance of the battery box. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0016] Reference Appendix Figure 1 ,exist Figure 1 In the diagram, 'a' points to the front view and 'b' points to the right-side view. These views are only used to understand the scheme.
[0017] Please see Figure 1-3 This utility model provides a technical solution: a battery box cover foam sealant applicator, including a processing table 1 and a cover plate 2, with the cover plate 2 located on the upper side of the processing table 1. A horizontal slot 3 is provided on the top of the processing table 1. A drive motor 31 is fixedly installed on the right side of the processing table 1. The left end of the drive motor 31 passes through the inner wall of the right side of the horizontal slot 3 and extends into the horizontal slot 3. A bidirectional screw 32 is fixedly installed on the output end of the drive motor 31 that extends into the horizontal slot 3. The bidirectional screw 32 is connected to a movable locking block 33 by a thread. The movable locking block 33 is slidably engaged with the horizontal slot 3.
[0018] There are two movable blocks 33. The tops of the two movable blocks 33 are arranged in a rectangular shape and fixedly installed with multiple clamping mechanisms for lifting the upper cover plate 2 to keep it horizontal. The clamping mechanisms are movably engaged with the upper cover plate 2.
[0019] In this embodiment, the upper cover plate 2 is flipped over and placed at the top center of the processing table 1. Through the cooperation of structures such as the bidirectional screw 32, multiple clamping mechanisms are driven to move synchronously to the middle position of the processing table 1. The edges of the upper cover plate 2 are clamped synchronously by multiple clamping mechanisms, and the upper cover plate 2 is squeezed upward to a certain height, so that the upper cover plate 2 is kept horizontal in the air. At the same time, the upper cover plate 2 is clamped and fixed by various methods such as squeezing and pressing after being suspended, so that the upper cover plate 2 is coated with foamed sealant in a horizontal state, thereby ensuring that the sealant is applied evenly. This even application will significantly improve the sealing effect of the battery box upper cover plate 2.
[0020] Specifically, the clamping mechanism includes a translation main board 4, a horizontal main block 5, a pressing block 54, and a support spring 55. The translation main board 4 is fixedly installed on the top of the moving card block 33. The horizontal main block 5 is symmetrically fixedly installed at both ends of the top of the translation main board 4. A locking slot 51 is provided on the left side of the horizontal main block 5 near the middle. The top inner wall of the locking slot 51 is rounded close to the left side. An arc corner 52 is provided at the angle between the left side of the horizontal main block 5 and the bottom inner wall of the locking slot 51. A vertical slot 53 is provided on the top inner wall of the locking slot 51. The pressing block 54 is slidably engaged in the vertical slot 53. The support spring 55 is fixedly installed on the top inner wall of the vertical slot 53. The bottom end of the support spring 55 is fixedly installed with the top of the pressing block 54. The upper cover plate 2 is movably engaged between the locking slot 51 and the pressing block 54. The length of the horizontal main block 5 near the top is less than the length of the horizontal main block 5 near the bottom.
[0021] In this embodiment, the upper cover plate 2 is lifted and suspended in the air during the clamping process by the cooperation of the internal structures of multiple clamping mechanisms, so that the upper cover plate 2 remains in a horizontal state after clamping.
[0022] Specifically, stabilizing blocks are fixedly installed at the bottom of the translation motherboard 4 near both ends, and the bottom of the stabilizing blocks is in contact with the top of the processing table 1.
[0023] In this embodiment, the horizontality of the translational main board 4 is increased during movement and force application by the stabilizing blocks on both sides.
[0024] Specifically, multiple friction strips are fixedly installed in a linear and uniform arrangement on the bottom of the pressing block 54.
[0025] In this embodiment, the stability of the upper cover plate 2 clamped between the pressing block 54 and the locking slot 51 is increased.
[0026] Specifically, the bottom left side of the pressing block 54 has a rounded corner design.
[0027] In this embodiment, when the edge of the upper cover plate 2 comes into contact with and is pressed against the pressing block 54, the pressing block 54 can be moved upward.
[0028] In use, the top cover plate 2 is flipped over and placed at the center of the top of the processing table 1. Due to the specific shape and structure of the top of the top cover plate 2 designed according to product requirements, the flipped top cover plate 2 is in a slightly tilted state. At this time, the drive motor 31 is started, and the drive motor 31 drives the bidirectional screw 32 to rotate. Under the restriction of the horizontal slot 3, the bidirectional screw 32 drives the moving blocks 33 on both sides to move synchronously to the middle position of the processing table 1. The moving blocks 33 on both sides drive their corresponding translation main plates 4 to move to the middle position of the processing table 1. The translation main plates 4 drive their symmetrical horizontal main blocks 5 at the top to move to the middle position of the processing table 1. After the horizontal main blocks 5 move to the middle position of the processing table 1 and contact the top cover plate 2, they continue to move. At this time, the edge of the top cover plate 2 moves upward under the squeezing guidance of the arc angle 52, so that the edge of the top cover plate 2 finally moves to the top inner wall of the locking slot 51. When the edge of the cover plate 2 moves to contact the pressing block 54, the pressing block 54 moves upward under the relative pressure of the upper cover plate 2 and compresses the support spring 55, so that the upper cover plate 2 is successfully locked between the locking slot 51 and the pressing block 54. At this time, the pressing block 54 generates a downward pressing force through the support spring 55 to press and fix the upper cover plate 2. Similarly, the working principle of the other arc corners 52 and the pressing block 54 is the same. The edge of the upper cover plate 2 is clamped synchronously by multiple clamping mechanisms, and the upper cover plate 2 is pressed upward to a certain height, so that the upper cover plate 2 is kept horizontal in the air. At the same time, the upper cover plate 2 is clamped and fixed by various methods such as squeezing and pressing after being suspended, so that the upper cover plate 2 is coated with foamed sealant in a horizontal state, thereby ensuring that the sealant is evenly applied. This even application will significantly improve the sealing effect of the battery box upper cover plate 2, thereby enhancing the sealing performance of the battery box.
[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
