Description

Technical Field

[0001] This utility model relates to the field of battery cell manufacturing technology, specifically to a top sealing and pressing device. Background Technology

[0002] The battery cell is the most basic component of a battery, typically an electrochemical device encapsulated in a metal casing. During cell manufacturing, the top of the encapsulated cell needs to be pressed and shaped to improve the flatness and efficiency of the cell's tabs, ensuring production quality. Therefore, a top-sealing pressing device is required. However, current top-sealing pressing devices still have the following shortcomings:

[0003] For example, patent document CN215815973U discloses a cell top sealing flattening device. This cell top sealing flattening device can flexibly switch between roller flattening and hot pressing shaping, allowing the same equipment to perform different shaping processes on different cells, saving equipment costs. However, during the flattening process, it cannot maintain pressure stability, which can easily lead to unevenness of the two films on the top seal of thick cells, resulting in defects.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed a top sealing and pressing device. Utility Model Content

[0005] The purpose of this invention is to provide a top sealing and pressing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a top sealing and compaction device, comprising a compaction operating table and auxiliary components. A servo motor is installed on the upper side inside the compaction operating table, and the output end of the servo motor is connected to a support column via a coupling. A connecting plate is provided on the upper side of the support column, and a connecting plate is installed on the side of the connecting plate. Four sets of connecting plates are provided, and the connecting plates are arranged in a ring at equal intervals on the side surface of the connecting plate. The connecting plates and the connecting plate are an integral structure that is tightly connected. A fixing plate is installed on the upper surface of the connecting plate away from the connecting plate. The auxiliary components are provided on the upper surface of the fixing plate, and the auxiliary components include a limiting inner slide groove, a limiting inner slide plate, a supporting upright plate, a supporting top plate, an auxiliary movable cylinder, and an auxiliary pressure plate.

[0007] Furthermore, the inner limiting groove is formed on the right end of the upper surface of the fixed plate, and the inner side of the inner limiting groove is slidably connected to the inner limiting slide plate.

[0008] Furthermore, a support plate is installed on the upper surface of the inner sliding plate of the limiting device, and a support top plate is provided on the upper left surface of the support plate.

[0009] Furthermore, an auxiliary movable cylinder is installed on the upper surface of the support top plate, and an auxiliary pressure plate is provided at the bottom of the auxiliary movable cylinder.

[0010] Furthermore, four sets of fixing plates and connecting plates are provided respectively, and the upper surface of the fixing plate is provided with a paving component for top sealing paving.

[0011] Furthermore, the paving assembly includes a fixed base, a mounting groove, a mounting strip, a limiting base, and a limiting groove, with the fixed base located on the left end of the upper surface of the fixed plate, and the upper surface of the fixed base having a mounting groove.

[0012] Furthermore, an installation slide bar is slidably connected to the inner side of the installation slide groove, and a limit seat is installed on the upper surface of the installation slide bar, with an installation slide groove formed at the front end of the upper surface of the limit seat.

[0013] Furthermore, the paving assembly also includes a support plate, a micro motor, and an upper pressure plate. The support plate is installed on both sides of the rear end of the fixed base. The micro motor is provided on the left surface of the support plate, and the output end of the micro motor is connected to the upper pressure plate through a coupling.

[0014] This utility model provides a top sealing and pressing device, which has the following beneficial effects:

[0015] 1. This utility model incorporates an auxiliary component, including an inner limiting groove, an inner limiting slide plate, a support upright plate, a support top plate, an auxiliary movable cylinder, and an auxiliary pressure plate. In use, after the upper pressure plate is pressed down, the support upright plate moves to the left, causing it to slide the inner limiting slide plate along the inner side of the inner limiting groove to the left. The sliding connection between the inner limiting slide plate and the inner limiting groove limits the movement of the support upright plate. The support upright plate then moves the support top plate to the left until it is above the upper pressure plate. At this point, the auxiliary movable cylinder is activated, causing the auxiliary pressure plate to move downwards. The auxiliary pressure plate maintains the stability of the upper pressure plate during installation. By adding an extra cylinder to press down the upper pressure plate during installation, the device increases pressure stability and reduces defects caused by unevenness in the two films of the thick battery cell top seal.

The assembly also includes a support plate, a micro motor, and an upper pressure plate. In use, the limiting seat is mounted on the upper side of the fixed base via a sliding connection between the mounting strip and the inner side of the mounting groove. Different sizes and models of limiting seats can be replaced according to actual production needs. The operator places the battery cell inside the limiting groove, starts the micro motor, and causes the micro motor to drive the upper pressure plate to rotate around the upper surface of the support plate, causing the upper pressure plate to press down and perform a top-sealing pressing operation on the battery cell. This allows the device to disassemble and replace limiting seats of different sizes and models, and achieves automatic pressing, improving processing efficiency. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4As shown, the top sealing and compaction device includes a compaction operating platform 1 and an auxiliary component 7. A servo motor 2 is installed on the upper side inside the compaction operating platform 1, and the output end of the servo motor 2 is connected to a support column 3 via a coupling. A connecting plate 4 is installed on the upper side of the support column 3, and a connecting plate 5 is installed on the side of the connecting plate 4. Four sets of connecting plates 5 are arranged in a ring at equal intervals on the side surface of the connecting plate 4. The connecting plates 5 and the connecting plate 4 are a tightly connected integrated structure. A fixing plate 6 is installed on the upper surface of the connecting plate 5 away from the connecting plate 4. The auxiliary component 7 is located on the upper surface of the fixing plate 6. 7 includes a limiting inner slide groove 701, a limiting inner slide plate 702, a supporting upright plate 703, a supporting top plate 704, an auxiliary movable cylinder 705, and an auxiliary pressure plate 706. The limiting inner slide groove 701 is opened at the right end of the upper surface of the fixed plate 6, and the limiting inner slide plate 702 is slidably connected to the inner side of the limiting inner slide groove 701. The supporting upright plate 703 is installed on the upper surface of the limiting inner slide plate 702, and the supporting top plate 704 is provided at the upper left surface of the supporting upright plate 703. The auxiliary movable cylinder 705 is installed on the upper surface of the supporting top plate 704, and the auxiliary movable cylinder 705 is provided at the bottom of the auxiliary movable cylinder 705.

[0024] The specific operation is as follows: When in use, after the upper pressure plate 808 is pressed down, the support plate 703 is moved to the left, so that the support plate 703 drives the inner sliding plate 702 to slide to the left along the inner side of the inner sliding groove 701. Through the sliding connection between the inner sliding plate 702 and the inner sliding groove 701, the movement of the support plate 703 is limited. The support plate 703 drives the support top plate 704 to move to the left until the support top plate 704 moves above the upper pressure plate 808. Then, the auxiliary moving cylinder 705 is activated, so that the auxiliary moving cylinder 705 drives the auxiliary pressure plate 706 to move downward. The auxiliary pressure plate 706 maintains the stability of the upper pressure plate 808 during laying.

[0025] Please refer to Figure 3 The fixed plate 6 and the connecting plate 5 are respectively provided in four sets. The upper surface of the fixed plate 6 is provided with a laying component 8 for top sealing laying. The laying component 8 includes a fixed seat 801, a mounting groove 802, a mounting strip 803, a limiting seat 804 and a limiting groove 805. The fixed seat 801 is located at the left end of the upper surface of the fixed plate 6. The upper surface of the fixed seat 801 is provided with a mounting groove 802. The mounting strip 803 is slidably connected to the inner side of the mounting groove 802. The upper surface of the mounting strip 803 is provided with a limiting seat 804. The front end of the upper surface of the limiting seat 804 is provided with a mounting groove 802. The laying component 8 also includes a support plate 806, a micro motor 807 and an upper pressure plate 808. The support plate 806 is installed on both sides of the rear end of the fixed seat 801. The micro motor 807 is provided on the left surface of the support plate 806. The output end of the micro motor 807 is connected to the upper pressure plate 808 through a coupling.

[0026] The specific operation is as follows: During use, the limit seat 804 is installed on the upper side 801 of the fixed seat by sliding the mounting strip 803 to the inner side of the mounting groove 802. Different sizes and models of limit seats 804 can be replaced according to actual production needs. Start the servo motor 2, so that the servo motor 2 drives the connecting plate 4 to rotate through the support column 3, and then drives the fixed plate 6 to rotate through the connecting plate 5, so that the limit seat 804 moves in front of the operator. The operator places the battery cell inside the limit groove 805, starts the micro motor 807, so that the micro motor 807 drives the upper pressure plate 808 to rotate around the upper surface of the support plate 806, so that the upper pressure plate 808 presses down to perform top sealing and pressing operation on the battery cell. At the same time, the servo motor 2 continues to drive the device to rotate, so that the limit seat 804, which has not been operated or has been pressed, moves in front of the operator to achieve continuous operation.

[0027] In summary, as Figures 1 to 4 As shown, in use, the top sealing and pressing device first installs the limiting seat 804 on the upper side 801 of the fixed seat by sliding the mounting strip 803 to the inner side of the mounting groove 802. Different sizes and models of limiting seats 804 can be replaced according to actual production needs. The servo motor 2 is started, causing the servo motor 2 to drive the connecting plate 4 to rotate through the support column 3, and then drive the fixed plate 6 to rotate through the connecting plate 5, so that the limiting seat 804 moves in front of the operator. The operator places the battery cell inside the limiting groove 805, starts the micro motor 807, and causes the micro motor 807 to drive the upper pressure plate 808 to rotate around the upper surface of the support plate 806, so that the upper pressure plate 808 presses down to perform the top sealing and pressing operation on the battery cell. After the upper pressure plate 808 presses down, it moves to the left. The support plate 703 causes the inner sliding plate 702 to slide to the left along the inner side of the inner sliding groove 701. The sliding connection between the inner sliding plate 702 and the inner sliding groove 701 limits the movement of the support plate 703. The support plate 703 causes the support top plate 704 to move to the left until the support top plate 704 moves above the upper pressure plate 808. Then, the auxiliary moving cylinder 705 is activated, causing the auxiliary moving cylinder 705 to move the auxiliary pressure plate 706 downward. The auxiliary pressure plate 706 maintains the stability of the upper pressure plate 808 during laying. At the same time, the servo motor 2 continues to drive the device to rotate, so that the limit seat 804, which has not been operated or has been laid, moves to the front of the operator, enabling continuous operation.
