Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and in particular to a battery cell feeding device for vertical adhesive application. Background Technology

[0002] With the rapid development of electric vehicles and automobiles, the power batteries used in vehicles have also developed rapidly. In the production process of lithium batteries, several cells need to be stacked and pressed into a cell module. Before this, adhesive tape with adhesive on both sides needs to be applied to the stacked surfaces of each cell.

[0003] In related technologies, the large-area adhesive application process for battery cells requires adhesive application equipment. This equipment includes a base, an adhesive feeding mechanism, a battery cell conveying mechanism, and a battery cell flipping mechanism. These components are mounted on the base, with the battery cell conveying mechanism positioned below the adhesive feeding mechanism. The adhesive feeding mechanism drives the continuous movement of the adhesive material. The battery cell is placed horizontally on the battery cell conveying mechanism with its large side facing upwards. The battery cell conveying mechanism and the adhesive feeding mechanism operate synchronously, completing single-sided adhesive application while the battery cell remains in a horizontal position. After single-sided adhesive application, the battery cell needs to be flipped by the battery cell flipping mechanism, from a horizontal position to an upright position and then back to a horizontal position, to achieve large-area adhesive application on the opposite side of the battery cell.

[0004] However, repeatedly flipping the battery cells can easily cause impact damage to the cells themselves, thereby reducing the quality of battery processing. Therefore, there is a need for a feeding device that can keep the battery cells in a standing position while moving. Utility Model Content

[0005] To address the issue of repeated cell flipping causing damage to the cells and thus reducing battery processing quality, this application provides a cell loading device for vertical adhesive application.

[0006] This application provides a battery cell feeding device for vertical adhesive application, which adopts the following technical solution:

[0007] A battery cell loading device for vertical adhesive application includes a base, a conveying assembly, a clamping assembly, a pressurizing assembly, and a clamping assembly. The conveying assembly is located inside the base and is used to convey the battery cells. The clamping assembly is located on the base and on opposite sides of the battery cell's direction of movement. The clamping assembly is used to clamp the battery cells to keep them in an upright position. A truss is provided on the base. The pressurizing assembly is slidably connected to the truss along the Z-axis and is used to cooperate with the conveying assembly to fix the battery cells. The clamping assembly is slidably connected to the truss along the X-axis and clamps and fixes the battery cells in the X-axis direction, ensuring that the battery cells always maintain an upright position.

[0008] By adopting the above technical solution, the battery cell moves into the conveying assembly in an upright posture. Then, the clamping assembly holds the battery cell upright, and the pressurizing assembly works in conjunction with the clamping assembly to further clamp and position the battery cell. After the clamping assembly releases the clamping assembly, it is easy for the clamping assembly to directly carry the battery cell in an upright posture to the adhesive application station. This facilitates the application of adhesive to the large side of the battery cell, reduces the number of flipping steps, greatly reduces the probability of impact damage to the battery cell, and effectively improves the battery processing quality.

[0009] Preferably, the conveying assembly includes a conveying chain, a first conveying roller, and a second conveying roller. The conveying chain is rotatably arranged around the base. The first and second conveying rollers are symmetrically arranged on opposite sides of the battery cell. The first conveying roller is located on the side where the adhesive surface of the battery cell is located. The surface of the first conveying roller is provided with an anti-stick coating.

[0010] Preferably, the pressurizing assembly includes a pressurizing drive and a pressurizing plate. The pressurizing drive is mounted on a truss, and the pressurizing plate is connected to the output end of the pressurizing drive. The truss is provided with a pressurizing rack, and the pressurizing plate is provided with a pressurizing gear, which meshes with the pressurizing rack.

Several flexible pressurizing wheels are provided, and the several flexible pressurizing wheels are sequentially rotatably connected to the abutment plate along the X-axis direction. The flexible pressurizing wheels abut against the battery cell.

[0012] Preferably, the pressurization assembly further includes a buffer frame, a connector, and a buffer member. The buffer frame is located on the side of the pressurization plate facing the base. The buffer frame is movably connected to the abutment plate via the connector. The buffer member is located between the buffer frame and the abutment plate.

[0013] Preferably, the connector includes a release rod, a movable rod, and a locking buckle. A connecting groove is provided on the abutment plate, the movable rod is inserted into the connecting groove, the release rod is disposed in the connecting groove and passes through the end of the movable rod, and the locking buckle is disposed at the end of the movable rod away from the release rod, and the movable rod is movably disposed in the locking buckle.

[0014] Preferably, the clamping assembly includes a clamping drive and a clamping plate. The clamping drive is disposed on the base, and the clamping plate is disposed at the output end of the clamping drive. The clamping drive controls the clamping plate to move toward the battery cell along the Y-axis direction. There are at least two clamping assemblies, and each pair of clamping assemblies forms a group. A group of clamping assemblies is symmetrically disposed on two opposite large surfaces of the battery cell along the X-axis direction.

[0015] Preferably, the clamping assembly includes a fixed clamping block, a clamping drive, and a clamping clamping block. The fixed clamping block is located at one end of the pressure plate, and the clamping drive is located at the end of the pressure plate away from the fixed clamping block. The clamping drive drives the clamping clamping block to move relative to the fixed clamping block along the X-axis direction, and the clamping clamping block cooperates with the fixed clamping block to clamp the battery cell.

[0016] Preferably, it also includes a transverse movement assembly, which includes a transverse movement drive, a transverse movement screw, and a transverse movement frame.

[0017] Preferably, the base is provided with a baffle, which includes a baffle cylinder and a baffle rod. The baffle cylinder is located on the base, and the baffle rod is connected to the piston rod end of the baffle cylinder. The baffle cylinder drives the baffle rod to pass into the conveying assembly, and the baffle rod is used to block the movement of the battery cell.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By combining the pressure-pressurizing component and the clamping component, the battery cell can be kept upright during the adhesive application process, which improves the stability of the battery cell, reduces the probability of damage to the battery cell itself, and improves the quality of battery production and processing.

[0020] 2. The battery cell moves on the conveying assembly until it abuts against the stop bar, that is, it moves into position. The conveyor chain stops running, realizing automated control. Then, the fixing block and the clamping block cooperate to clamp the battery cell and keep it in place so that the battery cell can be carried to continue moving, reducing the need for manual adjustment.

[0021] 3. With the setting of the abutment plate, flexible pressure roller and buffer, when the pressure plate moves toward the battery cell and abuts against the battery cell, the abutment plate and the flexible pressure roller will float slightly under the action of the buffer, reducing hard collisions to the battery cell and further protecting the battery cell.

[0027] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0028] This application discloses a battery cell feeding device for vertical adhesive application, referring to... Figure 1-2 The system includes a base 1, on which a conveying assembly 11, a clamping assembly 13, a transverse assembly 4, a pressurizing assembly 3, and a clamping assembly 5 are provided. The battery cell moves into the conveying assembly 11 in an upright position and is clamped and fixed by the clamping assembly 13, which facilitates the subsequent clamping and fixing of the battery cell by the pressurizing assembly 3 and the clamping assembly 5, so that the battery cell always maintains an upright position. Then, the transverse assembly 4 drives the battery cell to continue moving to the adhesive application station, which facilitates the adhesive application process on the large side of the battery cell.

[0029] Reference Figure 1 The conveying assembly 11 includes a conveyor chain 111, a first conveyor roller 112, and a second conveyor roller 113. The conveyor chain 111 is rotatably arranged around a base 1, and the base 1 has a built-in conveying drive source for driving the conveyor chain 111 to rotate. The first conveyor roller 112 and the second conveyor roller 113 are symmetrically arranged on opposite sides of the battery cell. The first conveyor roller 112 is located on the side where the adhesive surface of the battery cell is located. In order to facilitate the conveying of the battery cell after adhesive application, the roller surface of the first conveyor roller 112 is provided with an anti-stick coating.

[0030] Reference Figure 1The base 1 is also equipped with a baffle 12, which includes a baffle cylinder 121 and a baffle rod 122. The baffle cylinder 121 is fixedly connected to one side of the base 1, and the baffle rod 122 is connected to the piston rod end of the baffle cylinder 121. The baffle cylinder 121 drives the baffle rod 122 to penetrate into the conveying assembly 11. A sensor is provided on the baffle rod 122, and the sensor is electrically connected to the conveying drive source. When the baffle cylinder 121 drives the baffle rod 122 to penetrate into the conveying chain 111, the battery cell moves along the conveying chain 111. When the battery cell comes into contact with the baffle rod 122, the sensor detects the pressure and sends a signal to the conveying drive source, causing the conveying drive source to stop running and the conveying chain 111 to stop running synchronously.

[0031] Reference Figure 1 and 2 The clamping assembly 13 includes a clamping drive 131 and a clamping plate 132. The clamping drive 131 is mounted on the base 1, and the clamping plate 132 is fixedly connected to the output end of the clamping drive 131. The clamping drive 131 controls the clamping plate 132 to move towards the battery cell along the Y-axis. At least two clamping assemblies 13 are provided, with each pair of clamping assemblies 13 forming a group. Each group of clamping assemblies 13 is symmetrically arranged on two opposite large surfaces of the battery cell along the X-axis. Before the pressure assembly 3 and clamping assembly 5 clamp the battery cell, the clamping assembly 13 holds the battery cell in an upright position.

[0032] Reference Figure 1 , 2 In addition to the base 1, a truss 2 is also fixedly connected. The pressurizing assembly 3 includes a pressurizing drive 31 and a pressurizing plate 32. The pressurizing drive 31 is fixedly connected to the end of the truss 2, and the pressurizing drive 31 can be a pressurizing cylinder. The pressurizing plate 32 is fixedly connected to the output end of the pressurizing drive 31. A pressurizing rack 322 is fixedly connected to the truss 2, and a pressurizing gear 321 is rotatably connected to the pressurizing plate 32. The pressurizing gear 321 meshes with the pressurizing rack 322. When the pressurizing drive 31 operates, it drives the pressurizing plate 32 and the pressurizing gear 321 to move. The pressurizing gear 321 rotates along the pressurizing rack 322, which helps to ensure the stability of the movement of the pressurizing plate 32.

[0033] Reference Figure 1 and 2 The pressure plate 32 is provided with a transverse moving assembly 4. The transverse moving assembly 4 includes a transverse moving drive 41, a transverse moving screw 42 and a transverse moving frame 43. The transverse moving drive 41 is fixedly connected to one end of the pressure plate 32, the transverse moving screw 42 is connected to the output end of the transverse moving drive 41, and the transverse moving frame 43 is threadedly connected to the transverse moving screw 42.

[0034] Reference Figure 1 and 4The pressurizing component also includes a buffer frame 33, an abutment plate 34, and a buffer element 35. The buffer frame 33 is fixedly connected to the side of the transverse frame 43 facing the base 1. The buffer element 35 can be a buffer spring and is connected between the buffer frame 33 and the abutment plate 34. The buffer frame 33 and the abutment plate 34 are connected by a connector 36. The connector 36 includes a stop rod 361, a movable rod 362, and a locking buckle 363. A connecting groove is provided on the abutment plate 34, and the movable rod 362 is inserted into the connecting groove. The stop rod 361 is located in the connecting groove and passes through the end of the movable rod 362. The locking buckle 363 is located at the end of the movable rod 362 away from the stop rod 361, and is located on the side of the buffer frame 33 away from the abutment plate 34. The movable rod 362 moves through the buffer frame 33 and passes through the locking buckle 363.

[0035] After the battery cell is moved into place, the pressure drive 31 drives the pressure plate 32, the transverse frame 43, the buffer frame 33, and the abutment plate 34 to press down synchronously and abut against the battery cell. When the abutment plate 34 contacts the battery cell, the buffer 35 and the connecting piece 36 work together to achieve elastic buffering, reduce direct hard impact on the battery cell, and further protect the battery cell.

[0036] Reference Figure 1 and 4 To further protect the surface of the battery cell, the pressurizing assembly 3 also includes a flexible pressurizing wheel 341. Several flexible pressurizing wheels 341 are provided, and the several flexible pressurizing wheels 341 are sequentially rotatably connected to the abutment plate 34 along the X-axis. The flexible pressurizing wheels 341 abut against the battery cell to further provide cushioning.

[0037] Reference Figure 1 and 2 The clamping assembly 5 includes a fixed clamping block 51, a clamping drive 52, and a clamping clamping block 53. The fixed clamping block 51 is fixedly connected to one end of the transverse frame 43, the clamping drive 52 is fixedly connected to the transverse frame 43, and the clamping clamping block 53 is connected to the output end of the clamping drive 52. When the battery cell moves to abut against the stop bar 122, the battery cell stops moving. Then, the clamping drive 52 drives the clamping clamping block 53 to move relative to the fixed clamping block 51 along the X-axis direction. The clamping clamping block 53 cooperates with the fixed clamping block 51 to clamp the battery cell.

[0038] The implementation principle of a battery cell feeding device for vertical adhesive application according to an embodiment of this application is as follows:

[0039] The stop bar 122 extends, and the battery cell moves along with the conveyor chain 111. When the battery cell moves to abut against the stop bar 122, the conveyor chain 111 stops moving. The clamping plate 132 extends synchronously to clamp and fix the battery cell. Then, the abutment plate 34, carrying a flexible pressure roller 341, abuts against one side of the battery cell. Subsequently, the clamping block 53 cooperates with the fixing block 51 to clamp and fix the battery cell. Then, the transport frame continues to move with the battery cell to the adhesive application area to make room for the large surface of the battery cell, facilitating automatic adhesive application.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
