Description

Technical Field

[0001] This utility model relates to the field of battery assembly technology, specifically to a pressure bonding device. Background Technology

[0002] The adhesive bonding process for CTB battery modules is a crucial step in their manufacturing, primarily used to improve the overall performance, safety, and reliability of the battery module. During adhesive bonding, the battery cells are first placed into the module frame according to the design layout. Then, adhesive is precisely injected onto the sides or fixing points of the cells. Pressure is then applied using fixtures to ensure even distribution of the adhesive and to fill the gaps between the cells, fixing their positions and preventing displacement or loosening due to vibration or impact. This ensures the mechanical stability of the module during long-term use.

[0003] Existing battery module pressing equipment suffers from structural design flaws, making it difficult to control the pressing force and resulting in poor pressing effects. Chinese patent document CN219350308U discloses a battery pack pressing device, including a support frame and a pressure roller located on the side of the individual battery cell facing away from the adhesive layer. The pressure roller includes a first roller and a roller frame, with the roller rotatably connected to the roller frame, which is connected to the support frame. The pressure roller slides back and forth relative to the support frame, pressing against the side of the individual battery cell facing away from the adhesive layer and rolling. This pressing device uses the roller to apply pressure to the individual battery cell, causing the cell to squeeze the adhesive layer and expel air bubbles from the adhesive layer to the surrounding area, thus completing the pressing operation. However, using the roller to apply pressure makes it impossible to maintain stable pressure on the entire battery module for an extended period. The force during the pressing process cannot be precisely controlled, and the entire pressure roller cannot be adjusted for pressing battery packs of different sizes, making it unsuitable for pressing different battery packs. Utility Model Content

[0004] The technical problem to be solved by this invention is how to accurately control the force during the adhesive bonding process.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: This utility model provides a glue-pressing device, including a platform, a movable frame, a glue-pressing mechanism, and an adjustment component. The movable frame is slidably connected to the platform, the glue-pressing mechanism is connected to the movable frame, and the adjustment component is fixed to the top of the movable frame and drives the glue-pressing mechanism to move left and right. The glue-pressing mechanism includes a translation plate, a threaded rod, and a lifting plate. The translation plate is fixed, the threaded rod is threadedly connected to the translation plate, and the bottom of the threaded rod is rotatably connected to the lifting plate. The bottom of the lifting plate is provided with a detection plate and a glue-pressing plate, and the detection plate and the glue-pressing plate are connected by an elastic component.

[0006] Beneficial effects: The pressing device of this utility model places the battery module on the platform, adjusts the position of the moving frame by the guide rail, and then adjusts the position of the pressing mechanism by the adjusting component so that the pressing mechanism is directly above the battery module. Then, the threaded rod is rotated to press the battery module with glue through the pressing plate.

[0007] This invention utilizes a threaded rod and a lifting plate that are rotatably connected. Rotating the threaded rod causes the lifting plate to move up and down. The lifting plate is connected to a pressure plate via an elastic component. The pressure plate applies adhesive to the battery module, and the elastic component acts as a buffer during the application process. This embodiment incorporates a detection plate at the bottom of the lifting plate to monitor the force applied during the pressure process. The rotation of the threaded rod precisely adjusts the pressure force. Furthermore, it can maintain the optimal pressure force for a period of time, effectively improving the overall performance, safety, and reliability of the battery module after the pressure process.

[0008] Preferably, the detection plate is connected to a pressure display.

[0009] Beneficial effects: This utility model adjusts the pressure of the adhesive by displaying the pressure on the pressure monitor.

[0010] Preferably, a limiting post is provided between the lifting plate and the pressing plate. The limiting post passes through and is fixed to the lifting plate, and its initial position does not contact the pressing plate.

[0011] Beneficial effects: By setting a limiting post between the lifting plate and the pressing plate, this utility model ensures that the battery module is not damaged due to excessive pressing force while ensuring sufficient pressing force.

[0012] Preferably, a guide post is fixed on the lifting plate, and a guide cylinder is provided on the translation plate, with the guide post passing through the guide cylinder to the translation plate.

[0013] Beneficial effects: In order to improve the stability of the lifting plate movement, this utility model sets guide columns on the lifting plate and guide cylinders on the translation plate.

[0027] according to Figure 1-4 As shown, this embodiment provides a glue-pressing device, which includes a platform 10, a movable frame 20, a glue-pressing mechanism 30, and an adjusting component 40. The movable frame 20 is slidably connected to the platform 10, and is located above the platform 10. Specifically, guide rails 11 are provided on both sides of the platform 10, and a slider 21 is provided at the bottom of the movable frame 20. The slider 21 is connected to the guide rails 11, allowing the movable frame 20 to move along the X direction within the platform 10. The glue-pressing mechanism 30 is connected to the movable frame 20, and the adjusting component 40 is fixed to the top of the movable frame 20 and drives the glue-pressing mechanism 30 to move left and right, specifically, the glue-pressing mechanism 30 can move along the Y direction of the platform 10.

[0028] according to Figure 3 As shown, the movable frame 20 includes a slider 21, a height adjustment component, and a crossbeam frame 25. The height adjustment components are symmetrically arranged on both sides of the bottom of the crossbeam frame 25. The slider 21 is arranged at the bottom of the height adjustment component. The slider 21 matches the guide rail 11, so that the slider 21 can slide along the guide rail 11, thereby moving the movable frame 20 along the X direction of the shelf 10.

[0029] In this embodiment, the adhesive pressing device is equipped with a height adjustment component to accommodate different heights of the battery module, ensuring that the adhesive pressing mechanism 30 can precisely abut against the battery module for accurate adhesive pressing. The height adjustment component includes a base frame 22 and an adjustment frame 23. The base frame 22 has a first through hole 221, and the adjustment frame 23 has multiple second through holes 231 evenly distributed along its height. The adjustment frame 23 is fitted onto the top of the base frame 22. The first through hole 221 and the second through holes 231 are aligned and fixed by bolts 24. Thus, the adjustment frame 23 is fixed to the top of the base frame 22. Height adjustment is achieved by aligning the first through hole 221 with the second through holes 231 at different heights and fixing them with bolts 24.

[0030] according to Figure 4 As shown, the crossbeam frame 25 includes a crossbeam and a longitudinal bar 251, the crossbeam and the longitudinal bar 251 being connected perpendicularly to each other, and the crossbeam being fixed to the top of the height adjustment assembly. According to... Figure 2 As shown, the adhesive pressing mechanism 30 includes a translation plate 31, a threaded rod 33, a lifting plate 34, and an adhesive pressing plate 36. The translation plate 31 has through-hole blocks 311 on both sides. The longitudinal rod 251 can pass through the through-hole blocks 311, so that the moving frame 20 is slidably connected to the adhesive pressing mechanism 30. The through-hole blocks 311 can slide along the Y direction of the longitudinal rod 251, thereby driving the adhesive pressing mechanism 30 to slide along the Y direction.

[0031] The translation plate 31 is provided with a threaded hole 32. The threaded rod 33 is connected to the translation plate 31 through the threaded hole 32. One end of the rod is rotatably connected to the top of the lifting plate 34 through a bearing (not shown in the figure). The other end is provided with a handle 321. The bottom of the lifting plate 34 is provided with a detection plate 351. The four corners of the bottom of the detection plate 351 are provided with elastic components 35. The elastic components 35 can be springs. The bottom of the elastic component 35 is fixedly connected to the pressure plate 36. A pressure sensor (not shown) is installed on the detection plate 351, which is connected to the pressure display 38. When the battery module is placed at the bottom of the pressure plate 36, the handle 321 is rotated, and the threaded rod 33 moves downward relative to the translation plate 31, thereby driving the lifting plate 34 to move downward. The principle is the same as that of the lead screw pair, so that the elastic component 35 is compressed and generates a pressure force through the pressure plate 36. The pressure force is transmitted to the pressure display 38 through the pressure sensor and displayed until the optimal pressure force is reached. Then the handle 321 is stopped. The pressure plate 36 maintains the optimal pressure force on the battery module for a period of time, which can effectively improve the overall performance, safety and reliability of the battery module after the pressure treatment.

[0032] To prevent the lifting plate 34 from descending too far and causing excessive pressure on the adhesive, thus damaging the battery module, a limiting post 37 is provided between the lifting plate 34 and the adhesive plate 36. The limiting post 37 is fixed on both sides of the lifting plate 34 and passes through a through hole (not shown in the figure). The bottom of the limiting post 37 is not in contact with the adhesive plate 36 at its initial position. When the handle 321 is rotated, the lifting plate 34 moves downward. When the limiting post 37 comes into contact with the adhesive plate 36, the lifting plate 34 cannot move downward by rotating the handle 321. This ensures sufficient pressure on the adhesive while avoiding damage to the battery module due to excessive pressure on the adhesive.

[0033] To improve the stability of the lifting plate 34, a guide post 341 is fixed on the lifting plate 34, and a guide cylinder 312 is provided on the translation plate 31. The guide post 341 passes through the translation plate 31 via the guide cylinder 312. Through the limiting of the guide cylinder 312 and the guidance of the guide post 341, the lifting plate 34 moves up and down more stably.

[0034] The adjustment assembly 40 includes a lead screw 42 and a nut block 44. A bearing seat 41 is provided in the middle of the crossbeam. The lead screw 42 is fixed to the crossbeam through the bearing seat 41. The lead screw 41 is perpendicular to the guide rail 11. A rotating handle 43 is provided at one end. By rotating the lead screw 41 through the rotating handle 43, the lead screw 41 drives the nut block 44 to move, so that the pressing mechanism 30 moves along the Y direction of the platform 10.

[0035] The working principle of the adhesive bonding device in this embodiment is as follows: 1. Place the battery module on the platform 10. Move the moving frame 20 by the cooperation of the guide rail 11 and the slider 21 so that the moving frame 20 is above the battery module. Then, rotate the screw 41 by rotating the handle 43. The screw 41 drives the nut block 44 to move so that the pressing mechanism 30 is placed directly above the battery module. Finally, through the height adjustment component of the moving frame 20, the pressing plate 36 of the pressing mechanism 30 is fixed by bolt 24 to make it abut against the battery module, thus completing the movement before the pressing process.

[0036] 2. At this time, rotating the handle 321 causes the threaded rod 33 to move downward. The lifting plate 34 moves downward stably through the limiting of the guide cylinder 312 and the guidance of the guide post 341. This causes the elastic component 35 to be compressed by the pressure plate 36, generating a pressure-pressing force. The pressure-pressing force is transmitted to the pressure sensor through the pressure detection plate 351 and displayed by the pressure display 38. When the optimal pressure-pressing force is reached, the handle 321 is stopped. The pressure plate 36 maintains the optimal pressure-pressing force on the battery module for a period of time, which can effectively improve the overall performance, safety and reliability of the battery module after the pressure-pressing process.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
