Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology, specifically to a device that can effectively improve the installation of battery cells in the casing. Background Technology

[0002] The production process of lithium-ion square aluminum-cased batteries includes the casing process. This process involves a feeding device that pushes the flat bare cell into the empty aluminum casing. In order to facilitate convenient, efficient and quick assembly of the bare cell with the aluminum casing, the opening of the casing is widened before pushing the bare cell into the aluminum casing to ensure that the bare cell can enter the aluminum casing smoothly.

[0003] However, when encountering excessively thick bare cells, these devices become ineffective at pushing them into the aluminum casing. This often results in a series of problems, including the cell failing to enter smoothly, the Mylar membrane shifting or even breaking, and excessive pressure triggering machine alarms. To address these issues, a common approach is to add guide rails or pulleys inside the aluminum casing opening to assist the cell's entry. However, this method occupies valuable space within the casing, leading to space constraints. Another solution involves applying pressure to the top and bottom surfaces of the cell to control its thickness and opening size, then using a push rod to push it into the casing. However, this method is only effective when the cell's tail enters the casing. Throughout the cell's insertion process, the inability of the upper and lower pressure plates to continuously apply downward pressure, coupled with potential rebound of the cell, often leads to insertion anomalies, ultimately requiring manual rework. This is not only time-consuming and labor-intensive but also reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a device that can effectively improve the insertion of battery cells into the casing, so as to solve the problem that existing devices are difficult to effectively push ultra-thick bare battery cells into aluminum casings, which is time-consuming, labor-intensive, and reduces production efficiency.

[0005] A device that can effectively improve the installation of battery cells includes a worktable. One end of the top of the worktable is provided with a fixing mechanism for placing aluminum shells of different sizes. The fixing mechanism includes a placement plate on the top of the worktable, on which an aluminum shell is placed. An opening is opened on one side of the aluminum shell, and a bare battery cell is placed at the opening. A top cover is provided at the end of the bare battery cell away from the opening. A pusher is provided at the end of the top of the worktable away from the fixing mechanism, which can clamp the top cover and move the bare battery cell. A pressing mechanism is provided on the worktable at the opening to prevent the bare battery cell from expanding.

[0006] Preferably, the pressing mechanism includes a mounting frame on a workbench, with cylinders symmetrically arranged at both the upper and lower ends of the mounting frame. A bracket is fixedly connected to the output end of the cylinder, and a pressure roller is rotatably mounted on the bracket, with the pressure roller abutting against the upper and lower surfaces of the bare battery cell.

[0007] Preferably, the mounting bracket has a guide rail on its side wall, and the bracket has sliders fixed at both ends that slide along the guide rail.

[0008] Preferably, the top of the workbench has a through hole for the pressure roller below the bare battery cell to move.

[0009] Preferably, a gear is rotatably mounted on the top of the workbench at the bottom of the placement plate, and racks are meshed on both sides of the gear. Connecting rods are fixed at the far ends of the racks. A clamping plate is provided on the top of the connecting rod, and the aluminum shell is clamped between the clamping plates. A moving groove for the connecting rod to move is provided on the placement plate. A motor is fixed at the bottom of the workbench, and the output end of the motor is connected to the gear transmission.

[0010] Preferably, the surface of the clamping plate that contacts the aluminum shell is provided with a wear-resistant layer.

[0011] Preferably, the top of the placement plate is provided with multiple scale lines at the position of the moving groove.

[0012] The advantages of this utility model are as follows: This utility model provides a device that can effectively improve the insertion of battery cells into the casing. By setting up a pressing mechanism, pressure rollers are used to apply pressure to the upper and lower surfaces of the bare battery cell, ensuring stable pressing control throughout the insertion process. This further compresses the thickness of the bare battery cell. The pressure rollers can rotate as the bare battery cell is pushed forward without obstructing its movement. This facilitates effective control of the thickness and shape of the bare battery cell, avoiding abnormal insertion caused by expansion or rebound of the bare battery cell. It effectively improves the problem of the bare battery cell being difficult to push into the aluminum casing normally, saving time and effort and improving the production efficiency of the device. By setting up a fixing mechanism and adjusting the distance between the clamping plates, the device can adapt to aluminum casings of different sizes, improving the versatility and flexibility of the device.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 5 As shown, a device that can effectively improve the installation of battery cells includes a workbench 100. A fixing mechanism 200 for placing aluminum shells 104 of different sizes is provided at one end of the top of the workbench 100. The fixing mechanism 200 includes a placement plate 201 on the top of the workbench 100. An aluminum shell 104 is placed on the top of the placement plate 201. An opening 105 is provided on one side of the aluminum shell 104. A bare battery cell 102 is placed at the opening 105. A top cover 103 is provided at the end of the bare battery cell 102 away from the opening 105. A pusher 101 capable of clamping the top cover 103 and moving the bare battery cell 102 is provided at the end of the top of the workbench 100 away from the fixing mechanism 201. A pressing mechanism 300 for preventing the bare battery cell 102 from expanding is provided on the workbench 100 at the opening 105.

[0020] The aluminum shell 104 is fixedly placed on the placement plate 201 by the fixing mechanism 200. The top cover 103 is held by the pusher 101 located at the end of the worktable 100 away from the fixing mechanism 200, which drives the bare battery cell 102 to move into the aluminum shell 104. The bare battery cell 102 is installed into the aluminum shell 104 through the opening 105. At the same time, a pressing mechanism 300 is set to apply pressure throughout the process of the bare battery cell 102 being installed into the aluminum shell 104 to prevent the bare battery cell 102 from expanding. This is convenient, quick and effective to realize the automatic installation of the bare battery cell 102 into the shell. It avoids the bare battery cell 102 after being wrapped with Mylar film from hitting the opening 105 of the aluminum shell 104, which would cause damage to the Mylar film and affect the safety of the bare battery cell 102, thus improving the working efficiency of the device.

[0021] In this embodiment, the pressing mechanism 300 includes a mounting frame 301 disposed on the workbench 100. The mounting frame 301 is symmetrically provided with cylinders 302 at both its upper and lower ends. The output end of the cylinders 302 is fixedly connected to a bracket 305. A pressure roller 306 is rotatably disposed on the bracket 305. The pressure roller 306 abuts against the upper and lower surfaces of the bare battery cell 102. The top of the workbench 100 is provided with a through hole 307 for the pressure roller 306 below the bare battery cell 102 to move.

[0022] During the movement of the bare battery cell 102, the pressing mechanism 300 starts working, using the cylinder 302 to push the bracket 305 and the pressure roller 306 towards the position where the bare battery cell 102 is inserted into the casing. This causes the pressure roller 306 to abut against the upper and lower surfaces of the bare battery cell 102, applying a certain pressure to the bare battery cell 102 to a set value. The through hole 307 on the worktable 100 allows the lower part of the pressure roller 306 to continue applying pressure to the lower surface of the bare battery cell 102, ensuring stable pressing control throughout the casing process, controlling its thickness and shape, preventing expansion or rebound, and further compressing the thickness of the bare battery cell 102. The pusher 101 abuts against the top cover 10. 3. The bare battery cell 102 is pushed towards the aluminum shell 104, while the pressure roller 306 maintains constant pressure. The pressure roller 306 can rotate with the push of the bare battery cell 102 without obstructing its push. When the top cover 103 of the bare battery cell 102 approaches the roller, the upper and lower pressure rollers 306 move away from the bare battery cell 102 and stop working, avoiding collision between the pressure roller 306 and the top cover 103, enhancing the safety of the device, facilitating effective control of the thickness and shape of the bare battery cell 102, avoiding abnormal insertion caused by expansion or rebound of the bare battery cell 102, effectively improving the problem of the bare battery cell 102 being difficult to push into the aluminum shell 104 normally, saving time and effort, and improving the production efficiency of the device.

[0023] In this embodiment, the mounting bracket 301 has a guide rail 303 on its side wall, and the bracket 305 has sliders 304 fixed at both ends that slide along the guide rail 303.

[0024] The bracket 305 slides on the guide rail 303 of the mounting frame 301 via the slider 304 to adapt to the position change of the bare cell 102 during the movement, and guides the movement of the pressure roller 306, making the movement of the pressure roller 306 more stable and enhancing the stability and reliability of the device.

[0025] In this embodiment, a gear 208 is rotatably mounted on the top of the workbench 100 at the bottom of the placement plate 201. A rack 207 meshes with both sides of the gear 208. A connecting rod 206 is fixedly mounted on each of the far ends of the rack 207. A clamping plate 203 is mounted on the top of the connecting rod 206. The aluminum shell 104 is clamped between the clamping plates 203. A moving groove 202 for the connecting rod 206 to move is opened on the placement plate 201. A motor 204 is fixedly mounted on the bottom of the workbench 100. The output end of the motor 204 is connected to the gear 208 for transmission.

[0026] When the size of the aluminum shell 104 changes, the motor 204 is started. Through the meshing transmission of the gear 208 and the rack 207, the connecting rod 206 and the clamping plate 203 are moved. The distance between the clamping plates 203 is adjusted to accommodate aluminum shells 104 of different sizes. By adjusting the distance of the clamping plates 203 of the fixing mechanism 200, the device can adapt to aluminum shells 104 of different sizes, improving its versatility and flexibility.

[0027] In this embodiment, the surface of the clamping plate 203 that contacts the aluminum shell 104 is provided with a wear-resistant layer 205.

[0028] The wear-resistant layer 205 provided on the clamping plate 203 can protect the aluminum shell 104 from damage during the clamping process.

[0029] In this embodiment, the top of the placement plate 201 is provided with multiple scale lines at the position of the moving groove 202.

[0030] The movable groove 202 and scale lines on the placement plate 201 help the staff to quickly and accurately adjust the position of the clamping plate 203.

[0031] Working process and principle: In use, the aluminum shell 104 is placed on the placement plate 201. The motor 204 drives the gear 208 to rotate. The meshing of the gear 208 and rack 207 drives the connecting rod 206 and clamping plate 203 to move. Adjusting the distance between the clamping plates 203 fixes the aluminum shell 104 in place. By adjusting the distance between the clamping plates 203 of the fixing mechanism 200, the device can adapt to aluminum shells 104 of different sizes, improving versatility and flexibility. The pusher 101 at the end of the worktable 100 away from the fixing mechanism 200 clamps the top cover 103, driving the bare battery cell 102 to move towards the interior of the aluminum shell 104. The bare battery cell 102 is then installed into the aluminum shell 104 through the opening 105. Simultaneously, during the movement of the bare battery cell 102, the cylinder 302 pushes the bracket 305 and the pressure roller 306 towards the position where the bare battery cell 102 is inserted into the shell. The bracket 305 slides on the guide rail 303 of the mounting frame 301 via the slider 304, which in turn moves the pressure roller 306. The movement of roller 306 acts as a guide, making the movement of pressure roller 306 more stable. Pressure roller 306 abuts against the upper and lower surfaces of bare battery cell 102, applying a certain pressure to the bare battery cell 102 to a set value, ensuring stable pressing control throughout the entire casing process, controlling its thickness and shape, preventing expansion or rebound, and further compressing the thickness of bare battery cell 102. Push claw 101 abuts against top cover 103 and pushes it towards aluminum shell 104, while pressure roller 306 maintains constant pressure. Pressure roller 306 can move along with bare battery cell 102. The rotation of the pusher 02 will not obstruct the push of the bare cell 102. When the top cover 103 of the bare cell 102 approaches the roller, the upper and lower pressure rollers 306 move away from the bare cell 102 and stop working, avoiding collision between the pressure rollers 306 and the top cover 103, enhancing the safety of the device, effectively realizing the automatic insertion of the bare cell 102 into the shell, avoiding the bare cell 102 wrapped with Mylar film from hitting the opening 105 of the aluminum shell 104, causing damage to the Mylar film and affecting the safety of the bare cell 102, and improving the working efficiency of the device.

[0032] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
