Description

Technical Field

[0001] This utility model relates to the technical field of battery cell production equipment, and in particular to a battery cell casing device. Background Technology

[0002] Cell assembly is a crucial step in the cell structure packaging process, directly affecting the battery's sealing performance, shock resistance, and thermal management. For example, prismatic and cylindrical batteries require laser welding to ensure a sealed casing and prevent electrolyte leakage.

[0003] In some battery designs, the cell size is close to the limit of the internal space of the casing, and direct insertion can easily lead to compression. In order to optimize the cell insertion path, a flip-in insertion method is currently used.

[0004] However, for batteries with multiple stepped surfaces on the side, existing cell insertion devices may cause inaccurate positioning and unreasonable force during cell flipping and insertion, leading to cell deformation. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a battery cell insertion device that can ensure uniform force distribution on the multi-step surface of the casing, avoiding uneven force distribution on the casing that could affect the positioning accuracy of the casing and cause battery cell deformation.

[0006] The battery cell insertion device according to an embodiment of the present invention includes:

[0007] The shell cover positioning mechanism includes a first fixing component, a first short side push block and a second short side push block. The first fixing component is used to fix the shell cover, and the first short side push block and the second short side push block respectively push two stepped surfaces on the same side of the shell cover to position the shell cover.

[0008] A flipping platform is used to flip the battery cells into the casing.

[0009] A cell positioning mechanism is provided on the flipping table and includes a second fixing component for fixing the cell.

[0010] The battery cell insertion device according to the embodiment of this utility model has at least the following beneficial effects:

[0011] 1. This utility model, by setting a first short-side push block and a second short-side push block, and a first fixing component for fixing the shell cover, allows the first short-side push block and the second short-side push block to press the two stepped surfaces on the same side of the shell cover to position the shell cover. As a result, each stepped surface of the shell cover with multiple stepped surfaces on the side is subjected to uniform force, which helps to improve the uniformity of the force on the shell cover when the battery cell positioning mechanism presses and positions the shell cover, and avoids the situation where uneven force on the shell cover affects the positioning accuracy of the shell cover and causes deformation of the battery cell.

[0012] 2. This utility model provides a cell positioning mechanism on the flipping table. The cell positioning mechanism includes a second fixing component for fixing the cell, thereby facilitating the fixing of the cell and preventing the cell position from shifting when the flipping table flips and drives the cell into the casing, which would affect the accuracy of the cell insertion.

[0013] According to some embodiments of the present invention, the cell positioning mechanism further includes an electric slide table, which is used to adjust the radial position of the second fixing component along the flipping axis of the flipping table to adjust the cell insertion trajectory.

[0014] The advantages of this invention are: by setting up an electric slide, which is used to adjust the radial position of the second fixing component along the flipping axis of the flipping table to adjust the trajectory of the battery cell entering the casing, the radial position of the electric slide along the flipping axis of the flipping table when the flipping table drives the battery cell to flip and enter the casing can be freely adjusted by changing the radial position of the electric slide along the flipping axis of the flipping table. This prevents the battery cell from being deformed due to excessive pressure or from not being properly inserted into the casing, thereby improving the positioning accuracy of the battery cell entering the casing and avoiding battery cell deformation.

[0015] According to some embodiments of this utility model, one of the shell cover positioning mechanism and the electric slide is provided with a track block, and the other of the shell cover positioning mechanism and the electric slide is provided with a guide wheel. When the flipping table drives the battery cell to flip into the shell, the track block and the guide wheel cooperate to guide it.

[0016] The advantage of this invention is that by setting a track block in one of the housing positioning mechanism and the electric slide, and setting a guide wheel in the other, when the flipping table drives the battery cell to flip into the housing, the track block and the guide wheel cooperate to guide it, thereby making the trajectory of the battery cell flipping into the housing more stable and accurate, which in turn facilitates the accurate insertion of the battery cell into the housing.

[0017] According to some embodiments of the present invention, the second fixing component includes a battery cell conforming block fixture, which is used for vacuum adsorption to fix the battery cell.

[0018] The advantage of this invention is that by setting up a battery cell conforming block fixture, which is used for vacuum adsorption to fix the battery cell, it is convenient to fix the battery cell and avoid the battery cell being squeezed and deformed due to positional displacement when it is flipped into the shell.

[0019] According to some embodiments of the present invention, the second fixing component further includes a left positioning block and a right positioning block, the left positioning block and the right positioning block are respectively located on both sides of the battery cell conforming block fixture along the flipping axis of the flipping table, and the left positioning block and the right positioning block respectively position the left and right sides of the battery cell.

[0020] The advantages of this invention are: by setting a left positioning block and a right positioning block, the left positioning block and the right positioning block are respectively located on both sides of the battery cell conforming block fixture along the flipping axis of the flipping table. The left positioning block and the right positioning block position the left and right sides of the battery cell respectively, which is beneficial to positioning the left and right positions of the battery cell. In this way, the left and right sides of the battery cell can be accurately matched with the left and right sides of the shell cover when flipping into the shell.

[0021] According to some embodiments of the present invention, the left positioning block and the right positioning block can approach and move away from the battery cell conforming block fixture, and the left and right sides of the battery cell conforming block fixture respectively abut and limit the left positioning block and the right positioning block.

[0022] The advantages of this invention are: by allowing the left and right positioning blocks to approach and move away from the battery cell conforming block fixture, and with the left and right sides of the conforming block fixture respectively abutting and limiting the left and right positioning blocks, it can be understood that before the battery cell is installed, the left and right positioning blocks are far away from the conforming block fixture, thus ensuring sufficient space for the battery cell in the battery cell positioning mechanism, facilitating the installation of the battery cell on the battery cell positioning mechanism. After the battery cell is installed, the left and right positioning blocks approach the conforming block fixture to correct the positional deviation of the battery cell in the left and right directions during installation, so that the battery cell can be positioned within the range of the conforming block fixture. At the same time, the side length of the conforming block fixture is longer than the side length of the battery cell. When the left and right positioning blocks approach the conforming block fixture to position the battery cell, the left and right sides of the conforming block fixture respectively abut and limit the left and right positioning blocks, so that the left and right positioning blocks will not press on the battery cell, thus preventing the battery cell from deforming.

[0023] According to some embodiments of the present invention, the second fixing component further includes a front positioning block, which is located on the front side of the battery cell conforming block fixture, and is used to limit the front side of the battery cell.

[0024] The advantage of this invention is that by setting a front positioning block, which is located on the front side of the battery cell conforming block fixture, the front positioning block is used to limit the front side of the battery cell. Thus, when installing the battery cell, the battery cell can be aligned with the front positioning block, which facilitates the positioning of the battery cell in the front-back direction.

[0025] According to some embodiments of the present invention, the first fixing component includes a shell cover adsorption fixture, which is used for vacuum adsorption to fix the shell cover.

[0026] The advantage of this invention is that by setting up a shell cover adsorption fixture, which is used for vacuum adsorption to fix the shell cover, it is convenient to fix the shell cover and avoid the shell cover shifting position and squeezing and deforming the battery cell when it is flipped into the shell.

[0027] According to some embodiments of the present invention, the first fixing component further includes at least two limiting posts, the two limiting posts being located on both sides of the shell cover adsorption fixture along the flipping axis of the flipping table, and the two limiting posts limiting the left and right sides of the shell cover respectively.

[0028] The advantage of this invention is that by setting at least two limiting posts, which are located on both sides of the shell cover adsorption fixture along the flipping axis of the flipping table, the two limiting posts limit the left and right sides of the shell cover respectively. This facilitates the coarse positioning of the shell cover when clamping it, so that the shell cover can be clamped into the adsorption range of the shell cover adsorption fixture.

[0029] According to some embodiments of the present invention, the shell cover adsorption fixture is erected, and the limiting post is provided with a limiting protrusion on the side near the shell cover adsorption fixture. The limiting protrusion is used to limit the direction of the shell cover away from the shell cover adsorption fixture.

[0030] The advantage of this invention is that by providing a limiting flange on the side of the limiting post near the shell cover adsorption fixture, the limiting flange is used to limit the direction of the shell cover away from the shell cover adsorption fixture, thereby preventing the shell cover from tilting away from the shell cover adsorption fixture and detaching from the first fixing component during the clamping process.

[0031] According to some embodiments of the present invention, the shell positioning mechanism further includes an upright mounting platform, which is used to install the first fixing component, the first short side push block and the second short side push block. An auxiliary tooling is provided between the mounting platform and the flipping platform, which is used to assist in adjusting the installation angle between the mounting platform and the flipping platform.

[0032] The advantages of this invention are: by setting up an upright mounting platform, which is used to install the first fixing component, the first short-side push block and the second short-side push block, and by setting an auxiliary tool between the mounting platform and the flipping platform, the installation angle of the mounting platform and the flipping platform can be adjusted. Thus, when installing the mounting platform, the angle of the mounting platform can be fixed by using the auxiliary tool, which helps to improve the angular position accuracy of the mounting platform and the flipping platform after installation. In turn, the structural installation accuracy of the battery cell casing device is higher, which helps to ensure the matching accuracy of the battery cell and the casing.

[0043] The battery cell insertion device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0044] This utility model aims to provide an embodiment of a battery cell housing device.

[0045] Reference Figure 1 In this embodiment, the battery cell insertion device mainly includes a casing positioning mechanism 100, a flipping table 140, and a battery cell positioning mechanism 150.

[0046] Reference Figure 1 and Figure 2 For the housing positioning mechanism 100, the housing positioning mechanism 100 includes a first fixing component 110, a first short side push block 120 and a second short side push block 130. The first fixing component 110 is used to fix the housing cover. The first short side push block 120 and the second short side push block 130 respectively push the two stepped surfaces on the same side of the housing cover to position the housing cover. Thus, the force on each stepped surface of the housing cover with multiple stepped surfaces on the side is uniform, which is beneficial to improve the uniformity of the force on the housing cover when the cell positioning mechanism 150 pushes and positions the housing cover, and avoids the situation where uneven force on the housing cover affects the positioning accuracy of the housing cover and causes deformation of the cell.

[0047] In some specific embodiments, the housing positioning mechanism 100 further includes an upright mounting platform 270. The mounting platform 270 is used to install the first fixing component 110, the first short-side push block 120, and the second short-side push block 130. An auxiliary tooling 280 is provided between the mounting platform 270 and the flipping platform 140. The auxiliary tooling 280 is used to assist in adjusting the installation angle between the mounting platform 270 and the flipping platform 140. Thus, when installing the mounting platform 270, the angle of the mounting platform 270 is fixed by the auxiliary tooling 280, which helps to improve the angular position accuracy between the mounting platform 270 and the flipping platform 140 after installation. Consequently, the structural installation accuracy of the battery cell housing device is higher, which helps to ensure the housing matching accuracy between the battery cell and the housing.

[0048] In some specific embodiments, the first short-side push block 120 and the second short-side push block 130 can be slidably connected to the mounting platform 270. The mounting platform 270 is provided with a first motor and a second motor. The first motor and the second motor are respectively used to drive the first short-side push block 120 and the second short-side push block 130 to slide, thereby making the movement of the first short-side push block 120 and the second short-side push block 130 more stable.

[0049] Furthermore, the output end of the first motor can be provided with a first screw, and the output end of the second motor can be provided with a second screw. The first screw is threadedly connected to the first short-side push block 120, and the second screw is threadedly connected to the second short-side push block 130, thereby realizing the transmission between the first motor and the first short-side push block 120 and the transmission between the second motor and the second short-side push block 130.

[0050] In some specific embodiments, the first fixing component 110 includes a shell cover adsorption fixture 220, which is used for vacuum adsorption to fix the shell cover, thereby facilitating the fixing of the shell cover and preventing the shell cover from shifting position and causing the battery cell to be squeezed and deformed when it is flipped into the shell.

[0051] In some specific embodiments, the first fixing component 110 further includes at least two limiting posts 230. The two limiting posts 230 are respectively located on both sides of the shell cover adsorption fixture 220 along the flipping axis of the flipping table 140. The two limiting posts 230 limit the left and right sides of the shell cover respectively, thereby facilitating the coarse positioning of the shell cover when clamping it, so that the shell cover can be clamped into the adsorption range of the shell cover adsorption fixture 220.

[0052] In some specific embodiments, the shell cover adsorption fixture 220 is erected, and the limiting post 230 is provided with a limiting flange 240 on the side near the shell cover adsorption fixture 220. The limiting flange 240 is used to limit the shell cover in the direction away from the shell cover adsorption fixture 220, thereby preventing the shell cover from tilting away from the shell cover adsorption fixture 220 and detaching from the first fixing component 110 during the shell cover clamping process.

[0053] It is understandable that after the assembly of the battery cell housing is completed, the auxiliary tooling 280 can be disassembled to avoid the auxiliary tooling 280 interfering with the flipping table 140.

[0054] The flipping table 140 is used to drive the battery cell to flip and be inserted into the casing.

[0055] Specifically, the tilting table 140 can be tilted using a motor.

[0056] Reference Figure 1 and Figure 3 For the cell positioning mechanism 150, the cell positioning mechanism 150 is set on the flipping table 140. The cell positioning mechanism 150 includes a second fixing component 170, which is used to fix the cell. This makes it easier to fix the cell and avoids the cell position shifting when the flipping table 140 flips and drives the cell into the casing, thus affecting the accuracy of the cell entering the casing.

[0057] In some specific embodiments, the battery cell positioning mechanism 150 further includes an electric slide 160. The electric slide 160 is used to adjust the radial position of the second fixing component 170 along the flipping axis of the flipping table 140 to adjust the battery cell insertion trajectory. Thus, when the flipping table 140 drives the battery cell to flip and insert into the casing, by changing the radial position of the electric slide 160 along the flipping axis of the flipping table 140, the part of the battery cell that abuts against the casing can be freely adjusted, preventing the battery cell from being deformed due to excessive compression or the battery cell not being inserted into the casing. This improves the positioning accuracy of the battery cell insertion and avoids the deformation of the battery cell.

[0058] Specifically, the electric slide table 160 is slidably mounted on the tilting table 140, and the tilting table 140 is equipped with a third motor, which is used to drive the electric slide table 160 to slide.

[0059] Furthermore, the output end of the third motor is provided with a third screw, which is threadedly connected to the electric slide table 160. The third screw is used for transmission between the third motor and the electric slide table 160.

[0060] Furthermore, a first guide rail is provided on the tilting table 140, and the electric slide table 160 slides along the first guide rail, thereby making the sliding of the electric slide table 160 more stable.

[0061] In some specific embodiments, the second fixing component 170 includes a battery cell conforming block fixture, which is used for vacuum adsorption to fix the battery cell, thereby facilitating the fixing of the battery cell and preventing the battery cell from being squeezed and deformed due to positional displacement when it is flipped into the casing.

[0062] In some specific embodiments, the second fixing component 170 further includes a left positioning block 190 and a right positioning block 200. The left positioning block 190 and the right positioning block 200 are respectively located on both sides of the battery cell conforming block fixture along the flipping axis of the flipping table 140. The left positioning block 190 and the right positioning block 200 respectively position the left and right sides of the battery cell, thereby facilitating the positioning of the battery cell in the left and right directions. In turn, this allows the left and right sides of the battery cell to be accurately fitted and installed with the left and right sides of the casing when flipped into the casing.

[0063] Furthermore, the left positioning block 190 and the right positioning block 200 can approach and move away from the battery cell profiling block fixture, and the left and right sides of the battery cell profiling block fixture respectively abut and limit the left positioning block 190 and the right positioning block 200.

[0064] Understandably, before the battery cell is installed, the left positioning block 190 and the right positioning block 200 are far away from the battery cell conforming block fixture, thus providing sufficient space for the battery cell installation in the battery cell positioning mechanism 150, facilitating the installation of the battery cell on the battery cell positioning mechanism 150. After the battery cell is installed, the left positioning block 190 and the right positioning block 200 move closer to the battery cell conforming block fixture to correct the positional deviation of the battery cell in the left and right directions during installation, so that the battery cell can be positioned within the range of the battery cell conforming block fixture. At the same time, the side length of the battery cell conforming block fixture is longer than the side length of the battery cell. When the left positioning block 190 and the right positioning block 200 move closer to the battery cell conforming block fixture to position the battery cell, the left and right sides of the battery cell conforming block fixture respectively abut and limit the left positioning block 190 and the right positioning block 200, so that the left positioning block 190 and the right positioning block 200 will not press on the battery cell, thus preventing the battery cell from deforming.

[0065] Furthermore, the left positioning block 190 and the right positioning block 200 are slidably connected to the electric slide table 160, which is provided with a second guide rail and a third guide rail. The second guide rail and the third guide rail guide the left positioning block 190 and the right positioning block 200 respectively, thereby making the movement of the left positioning block 190 and the right positioning block 200 more stable.

[0066] Furthermore, the left positioning block 190 and the right positioning block 200 can be moved using a motor.

[0067] In some specific embodiments, the second fixing component 170 further includes a front positioning block 210, which is located on the front side of the battery cell conforming block fixture. The front positioning block 210 is used to limit the front side of the battery cell, so that when installing the battery cell, the battery cell can be aligned with the front positioning block 210, which facilitates the positioning of the battery cell in the front-back direction.

[0068] It is understandable that when installing the battery cell, pushing the battery cell against the front positioning block 210 can align the battery cell with the front positioning block 210, thereby achieving the front-back positioning of the battery cell.

[0069] In some specific embodiments, one of the housing positioning mechanism 100 and the electric slide 160 is provided with a track block 250, and the other of the housing positioning mechanism 100 and the electric slide 160 is provided with a guide wheel 260. When the flipping table 140 drives the battery cell to flip and enter the housing, the track block 250 and the guide wheel 260 cooperate to guide, thereby making the trajectory of the battery cell flipping and entering the housing more stable and accurate, which in turn is conducive to the accurate entry of the battery cell into the housing.
