[0002] In the production process of battery modules, multiple battery cells are typically pressed together to form a battery module with a stable structure and reliable electrical performance. In existing technologies, servo motors are set with a fixed drive speed. If the drive speed is set too low, the extrusion plate moves slowly, resulting in low battery module forming efficiency. If the drive speed is set too high, the extrusion plate moves too fast, which can easily damage the battery module, affecting the overall performance and safety of the module. Utility Model Content

[0003] The purpose of this invention is to provide a battery extrusion device to improve the forming efficiency of battery modules without damaging them.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a battery compression device, comprising: a movable chassis and a control chassis disposed on the side of the movable chassis; a platform for stacking and leveling batteries is provided on the top of the movable chassis; a pushing compression component is provided at one end of the platform for pushing the batteries to move in a first direction; a fine pushing compression component is provided at the other end of the platform for pushing the batteries to move in the opposite direction to the first direction; the front end of the fine pushing compression component has an adjustable contact buffer compression part; by pushing the compression component, the batteries leveled on the platform are pushed to move toward the fine pushing compression component; the fine pushing compression component drives the contact buffer compression part to gradually apply compression force to the batteries, thereby compressing the batteries on the platform.

[0005] Furthermore, the entire platform includes a horizontal plate, on both sides of the horizontal plate along its length, there are strip-shaped locking grooves at equal intervals, and each strip-shaped locking groove has an inner step; a movable chassis on one side of the horizontal plate is provided with multiple adjustable brackets, which are equally spaced along the length of the horizontal plate; a crossbar with adjustable height is connected to the multiple adjustable brackets, and by pushing the battery toward the crossbar, one end face of the battery contacts the end face of the crossbar.

[0006] Furthermore, the end face of the movable chassis is provided with connecting holes that are set along the length of the horizontal plate and correspond to the positions of the strip locking grooves on both sides. A connector passes through the strip locking groove and connects to the connecting holes to fix the horizontal plate. The end face of the movable chassis on one side of the connecting hole is also provided with fixing holes that connect to the pushing and pressing component and the fine pushing and pressing component. The fixing holes are set at equal intervals along the length of the movable chassis.

[0007] Furthermore, the pushing and pressing component includes a base connected to a fixing hole in a movable chassis. A balance support assembly is slidably mounted on the base. A power drive component is mounted on the base between the balance support assembly. A push plate is mounted on the same end of the power drive component and the balance support assembly. The push plate is equipped with a first pressing block. The power drive component pushes the push plate to move the first pressing block toward the battery. When the first pressing block is subjected to force, the balance support assembly maintains the force balance on both sides of the push plate.

[0008] Furthermore, the balance support assembly includes first bushings symmetrically arranged on both sides of the base, with first push rods slidably mounted on the two first bushings, and one end of each of the two first push rods inserted into a first push plate.

[0009] Furthermore, the precision extrusion component includes a base connected to a fixing hole in a movable chassis. The base is equipped with an adjustable plate that can be adjusted vertically. The adjustable plate is equipped with an extrusion cylinder, and a contact buffer extrusion part is located at the output end of the extrusion cylinder. The contact buffer extrusion part is equipped with a fixed plate, and the fixed plate is equipped with a second pressure block. The adjustable plate is slidably equipped with an interleaved balancing assembly connected to the fixed plate. The contact buffer extrusion part is driven to move towards the battery by the extrusion cylinder, so that the force of the second pressure block pushing the battery is opposite to the force pushing the extrusion component, thereby achieving extrusion of the battery. The interleaved balancing assembly prevents the fixed plate from tilting due to uneven force.

[0010] Furthermore, the contact buffer extrusion part includes a shaft seat connected to the output end of the extrusion electric cylinder and a connecting sleeve connected to the fixed plate. Multiple adjusting shafts are connected between the shaft seat and the connecting sleeve, and one end of the adjusting shaft moves through the shaft seat and is threadedly connected to the connecting sleeve. Each adjusting shaft is fitted with a compression spring.

[0011] Furthermore, the staggered balancing assembly includes second bushings diagonally disposed on one side of the adjusting plate, and two second bushings are slidably provided with second push rods connected to the fixed plate, with one end of each second push rod inserted into the fixed plate.

[0013] Furthermore, the height adjustment assembly includes a worm gear screw jack, one end of which is connected to the adjusting plate via a bearing seat, and a handwheel is provided on the input shaft of the worm gear screw jack.

[0014] The beneficial effects of this invention are as follows: By placing the batteries on a platform, operators or robotic arms push the batteries to keep all battery end faces on the same plane. Then, the pushing and pressing component moves all the batteries towards the precision pushing and pressing component. Simultaneously, the precision pushing and pressing component drives the contact buffer pressing part to gradually apply pressure to the batteries, causing them to be tightly pressed together under uniform and appropriate pressure. This ensures the forming efficiency of the battery module and effectively avoids damage to the battery module due to excessive pressing speed or pressure, thereby improving the overall performance and safety of the battery module. This invention, by setting up the pushing and pressing component and the precision pushing and pressing component, and cooperating with the adjustable contact buffer pressing part, can flexibly adjust the pressing speed and force according to actual needs, improving the forming efficiency of the battery module and avoiding damage to the battery module due to excessive pressing speed or force, thus ensuring the overall performance and safety of the module.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] like Figure 1 and Figure 2As shown, this embodiment provides a battery compression device, which includes a movable housing 10 and a control housing 11 located on the side of the movable housing 10. Multiple casters 12 and feet 13 are provided at the bottom of the movable housing 10 and the bottom of the control housing 11. Two rows of symmetrically arranged connecting holes and two rows of symmetrically arranged fixing holes at equal intervals are provided on the working end face along the length of the movable housing 10. The fixing holes are located on the side of the connecting holes. A platform 20 is provided on the movable housing 10, and the platform 20 is connected and fixed to the connecting holes by screws. The operator can place the battery to be compressed. The battery is placed on the platform 20. The movable chassis 10 is also provided with a pushing and pressing component 30 that pushes the battery to move in the first direction and a fine pushing and pressing component 40 that pushes the battery to move in the opposite direction. The pushing and pressing component 30 is fixed to a fixing hole at one end by screws, and the fine pushing and pressing component 40 is fixed to a fixing hole at the other end by screws. The pushing and pressing component 30 pushes the flattened battery on the platform 20 to move towards the fine pushing and pressing component 40. The fine pushing and pressing component 40 drives the contact buffer pressing part 44 to gradually apply pressing force to the battery, so that the batteries on the platform 20 are pressed together.

[0023] like Figure 3 As shown, in this embodiment, the platform 20 includes a horizontal plate 21. The horizontal plate 21 has equally spaced strip-shaped locking grooves on both sides along its length. Each strip-shaped locking groove has an inner step, and screws pass through the grooves to connect to the connecting holes. A movable housing 10 located on one side of the horizontal plate 21 has multiple adjustable supports 22, which are equally spaced along the length of the horizontal plate 21. Each adjustable support 22 is connected to a height-adjustable crossbar 23. Each adjustable support 22 has a vertical strip groove, and screws pass through these grooves to fix the crossbar 23 to the support 22. By loosening the screws, the height of the crossbar 23 can be adjusted. A battery can be pushed towards the crossbar 23 manually or by a robotic arm, so that one end of the battery contacts the end of the crossbar 23. To prevent the battery from tilting up when it comes into contact with the crossbar 23, the height of the crossbar 23 can be located at the middle of the battery, slightly higher than the middle of the battery, or slightly lower than the middle of the battery. By setting the entire platform 20 to precisely align one end of the placed battery, problems such as uneven compression or damage caused by battery misalignment can be effectively avoided.

[0024] like Figure 4As shown, in this embodiment, the pushing and pressing component 30 includes a base 31 connected to a fixing hole in the movable housing 10. A balance support assembly 32 is slidably mounted on the base 31. A power drive component 33 is mounted on the base 31 between the balance support assemblies 32. In this embodiment, the power drive component 33 is a cylinder. A push plate 34 is mounted on the same end of the power drive component 33 and the balance support assembly 32. The push plate 34 is equipped with a first pressing block 35. During operation, the power drive component 33 drives the push plate 34 to move towards the battery. The first pressing block 35 then moves closer to the battery and eventually contacts it. Under the continuous action of the power drive component 33, the first pressing block 35 applies pressure to the battery. At the same time, the balance support assembly 32 stabilizes the push plate 34, ensuring that the push plate 34 does not shift during movement. This ensures that the first pressing block 35 presses the battery evenly and stably, thereby realizing the pressing operation of the pushing and pressing component 30 and the fine pushing and pressing component 40 on the battery.

[0025] In this embodiment, the balance support assembly 32 includes first bushings 320 symmetrically arranged on both sides of the base 31. First push rods 321 are slidably mounted on the two first bushings 320. The first push plate 34 with the two first push rods 321 is provided with an inlay groove and a threaded through hole in the inlay groove. One end of each of the two first push rods 321 is inserted into the inlay groove of the first push plate 34 and connected to the first push rods 321 by screws passing through the threaded through hole, so that the first push rods 321 are fixed to the first push plate 34. By setting the balance support assembly 32, not only is the stability of the push plate 34 enhanced during the movement, but the pressure applied by the power drive component 33 can also be effectively dispersed, ensuring that the squeezing effect of the first pressure block 35 on the battery is more uniform.

[0026] like Figure 5 and Figure 6 As shown, in this embodiment, the precision pushing and squeezing component 40 is used to cooperate with the pushing and squeezing component 30 to squeeze the battery. The precision pushing and squeezing component 40 includes a base 41 connected to a fixing hole in the movable housing 10. The base 41 is provided with an adjusting plate 42 that can be adjusted vertically. The adjusting plate 42 is provided with a squeezing cylinder 43. The output end of the squeezing cylinder 43 is provided with a contact buffer squeezing part 44. The contact buffer squeezing part 44 is provided with a fixing plate 45. The fixing plate 45 is provided with a second pressure block 46. The adjusting plate 42 is slidably provided with an interlaced balance assembly connected to the fixing plate 45. Component 47; During operation, the extrusion cylinder 43 drives the fixed plate 45 to move towards the battery, and the second pressure block 46 moves closer to the battery and eventually contacts it. Under the continuous action of the extrusion cylinder 43, the second pressure block 46 applies pressure to the battery. At the same time, the staggered balancing component 47 stabilizes the fixed plate 45, ensuring that the fixed plate 45 does not shift during movement, preventing the fixed plate 45 from tilting due to uneven force, and ensuring that the second pressure block 46 extrudes the battery evenly and stably. Together with the pushing extrusion component 30, it completes the extrusion operation on the battery.

[0027] The contact buffer compression part 44 is used to buffer the second pressure block 46 when it comes into contact with the pushed battery, preventing a strong impact when the second pressure block 46 contacts the battery instantly. In this embodiment, the main structure of the contact buffer compression part 44 includes a shaft seat 440 connected to the output end of the compression cylinder 43 and a connecting sleeve 441 connected to the fixing plate 45. Multiple adjusting shafts 442 are connected between the shaft seat 440 and the connecting sleeve 441, and one end of the adjusting shaft 442 moves through the shaft seat 440 and is threaded to the connecting sleeve 441. Each adjusting shaft 442 is fitted with a compression spring 443. When the second pressure block 46... As the device approaches the battery, the connecting sleeve 441 moves accordingly, the adjusting shaft 442 slides within the shaft seat 440, and the compression spring 443 is compressed, generating elastic deformation. This absorbs the impact force of the second pressure block 46 upon contact with the battery, thus providing a buffering effect. By adjusting the threaded connection position between the adjusting shaft 442 and the connecting sleeve 441, the initial compression amount of the compression spring 443 can be adjusted. This allows for flexible adjustment of the buffering force of the contact buffer compression part 44 according to different battery compression requirements, ensuring that the second pressure block 46 contacts the battery smoothly and gently, avoiding damage to the battery due to strong impacts, and also ensuring the stability and accuracy of the compression process.

[0028] In this embodiment, the staggered balancing assembly 47 includes second bushings 470 diagonally disposed on one side of the adjusting plate 42. Two second bushings 470 are slidably mounted with second push rods 471 connected to the fixed plate 45. The fixed plate 45 on the side corresponding to the second push rods 471 has an inlay groove, and the inlay groove has a threaded through hole. One end of each of the two second push rods 471 is inserted into the inlay groove of the fixed plate 45, and screws are passed through the threaded through hole to connect with the second push rods 471, thus fixing the second push rods 471 to the fixed plate 45. By setting the staggered balancing assembly 47, the fixed plate 45 can maintain balance during movement, preventing the fixed plate 45 from tilting or shifting when subjected to uneven force, ensuring the stability and reliability of the entire battery compression device during operation.

[0029] In order to ensure that the force of the precision extrusion component 40 is positioned in the middle of the battery according to the battery specifications, the adjusting plate 42 is provided with multiple adjusting slots connected to the base 41. A threaded connecting rod passes through the adjusting slots and is threadedly connected to the base 41, thus fixing the adjusting plate 42 to the base 41. The base 41 is also provided with a height adjusting assembly 48 connected to the adjusting plate 42. The height adjusting assembly 48 includes a worm gear screw jack 480. One end of the screw on the worm gear screw jack 480 is connected to the adjusting plate 42 through a bearing seat. A handwheel 481 is provided on the input shaft of the worm gear screw jack 480. After loosening the threaded connecting rod, the worm gear screw jack 480 starts to work by rotating the handwheel 481. The internal worm gear transmission mechanism converts the rotational motion of the handwheel 481 into the linear motion of the screw. The screw rises or falls smoothly under the support of the bearing seat, thereby driving the adjusting plate 42 to adjust the height. When the adjusting plate 42 is moved to the appropriate position so that the force of the precision pushing and pressing component 40 can be accurately positioned in the middle of the battery, tighten the threaded connecting rod again to firmly fix the adjusting plate 42 on the base 41. This ensures that the adjusting plate 42 will not shake or shift during the pressing process, thereby ensuring that the force applied by the precision pushing and pressing component 40 to the battery is stable and accurate, meeting the pressing requirements of batteries of different specifications.

[0030] It should be noted that the base 31 is provided with an adjustable balance support assembly 32 and a power drive component 33 mounting plate. The mounting plate has strip grooves on both sides and threaded holes corresponding to the strip grooves are opened in the base 31. The mounting plate is fixed on the base 31 by connecting the strip grooves and threaded holes with screws. By loosening the screws, the positions of the balance support assembly 32 and the power drive component 33 can be adjusted. With the force of the precision pushing and squeezing component 40, they can be accurately positioned in the middle of the battery.

[0031] In summary, by placing the batteries on the platform 20 and having an operator or robotic arm push them to keep all battery faces on the same plane, pressing the start button on the front of the movable housing 10 sends a command to the control housing 11, which then controls the operation of the pushing extrusion component 30 and the fine pushing extrusion component 40. The pushing extrusion component 30 pushes all the batteries toward the fine pushing extrusion component 40, while the fine pushing extrusion component 40 drives the contact buffer extrusion part 44 to gradually apply extrusion pressure to the batteries. This ensures that the batteries are tightly compressed together under uniform and appropriate pressure, which not only guarantees the forming efficiency of the battery module but also effectively avoids damage to the battery module due to excessive extrusion speed or pressure, thereby improving the overall performance and safety of the battery module.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
