Description

Technical Field

[0001] This application relates to the field of lithium battery production equipment technology, and in particular to a cell module extrusion assembly device. Background Technology

[0002] A battery cell module consists of multiple battery cells, end plates at both ends, and steel strips. If the battery cell module is made up of two rows of battery cells, the battery cells are usually first assembled into two rows of battery cells. Then, the two rows of battery cells are merged along the width direction by a battery cell module extrusion assembly device. The two rows of battery cells are fixed together by adhesive strips. The battery cell module extrusion assembly device then attaches the end plates to the battery cell module along the length direction of the two rows of battery cells. The battery cell module extrusion assembly device then extrudes the battery cell module to facilitate the subsequent application of steel strips.

[0003] However, in actual production, the existing battery cell module extrusion assembly device first merges two rows of battery cells along the width direction. Because there is an adhesive strip between the two rows of battery cells, the position of the two rows of battery cells along the length direction cannot be adjusted. If the two rows of battery cells are not aligned in the length direction, they can only be reassembled. Utility Model Content

[0004] The purpose of this application is to provide a battery cell module extrusion assembly device to solve the above-mentioned problems existing in the existing battery cell module extrusion assembly devices.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application discloses a battery cell module extrusion assembly device, which includes a base, a support portion, and an extrusion portion, wherein:

[0007] The carrier includes a first drive assembly and two carrier members, which are spaced apart and slidably mounted on a base along a first horizontal direction. Each carrier member is configured to carry a row of battery cells extending along a second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction. The drive end of the first drive assembly is connected to at least one carrier member. The first drive assembly is configured to drive the two carrier members to move closer to or further away from each other along the first horizontal direction.

[0008] The extrusion section includes a second drive assembly and two transverse members. The two transverse members are slidably mounted on the base along the second horizontal direction and are arranged opposite each other on the outer sides of the bearing section in the second horizontal direction. Two extrusion plates are slidably mounted on the side of each transverse member near the bearing section along the first horizontal direction. Each extrusion plate corresponds to a row of battery cells. The drive end of the second drive assembly is connected to at least one transverse member. The second drive assembly is configured to drive the two transverse members to move closer or further away from each other along the second horizontal direction. The second drive assembly drives the two transverse members to move closer to each other, so that the two extrusion plates on each transverse member abut against one end of the two rows of battery cells carried on the two bearing members in the second horizontal direction, thereby synchronously extruding the two rows of battery cells in the second horizontal direction.

[0009] After the extrusion section synchronously extrudes the two rows of cells in the second horizontal direction, the first drive assembly drives the two carriers to move closer to each other in order to merge the two rows of cells carried on the two carriers in the first horizontal direction.

[0010] The battery cell module extrusion assembly device proposed in this application has two extrusion plates on each of the two transverse moving parts, with each extrusion plate corresponding to one row of battery cells. The second drive assembly, in cooperation with the two transverse moving parts, first extrudes the two ends of the two rows of battery cells in the second horizontal direction (the length direction of the two rows of battery cells), and then merges the two rows of battery cells in the first horizontal direction (the width direction of the two rows of battery cells) through the cooperation of the first drive assembly and the two bearing parts, ensuring that the two rows of battery cells are aligned in the length direction after assembly, thereby improving the assembly quality of the two rows of battery cells.

[0011] Optionally, a reset elastic element is provided between the two extrusion plates. The first end of the reset elastic element is connected to one of the extrusion plates, and the second end of the reset elastic element is connected to the other extrusion plate. The reset elastic element is configured to push the two extrusion plates apart and reset them after the two extrusion plates leave the cells of the corresponding column.

[0012] By setting a reset elastic element between the two extrusion plates, the two extrusion plates can be automatically reset after the two rows of cells are extruded in the second horizontal direction, which facilitates the assembly of the next set of two rows of cells.

[0013] Optionally, both extrusion plates can be mounted on the transverse member in a reciprocating manner along the first horizontal direction;

[0014] Alternatively, one of the extrusion plates is fixedly mounted on the transverse moving member, while the other extrusion plate is reciprocally mounted on the transverse moving member along the first horizontal direction.

[0015] By setting up two extrusion plates, two installation methods are provided that enable the two extrusion plates to move closer or further away from each other along the first horizontal direction as the two rows of cells are aligned, which can meet two different application scenarios.

[0016] Optionally, the extrusion plate is reciprocally mounted on the transverse moving member in a first horizontal direction, and a first sliding guide pair is provided between the extrusion plate and the transverse moving member, wherein:

[0017] The first sliding guide pair includes a first linear guide rail and a first slider. The first linear guide rail extends along a first horizontal direction and is fixed on the transverse member. The first slider is fixed on the extrusion plate and slidably sleeved on the first linear guide rail.

[0018] Alternatively, the first linear guide rail extends along a first horizontal direction and is fixed to the extrusion plate, and the first slider is fixed to the transverse member and slidably sleeved on the first linear guide rail.

[0019] By setting a first sliding guide pair between the extrusion plate and the transverse moving member, the stability of the extrusion plate reciprocating along the first horizontal direction is improved.

[0020] Optionally, each carrier can be reciprocated on the base in a first horizontal direction;

[0021] Alternatively, one of the carriers may be fixedly mounted on the base, while the other carrier may be reciprocally mounted on the base along the first horizontal direction;

[0022] The carrier component is reciprocally mounted on the base in a first horizontal direction, and a second sliding guide pair is provided between the carrier component and the base, wherein:

[0023] The second sliding guide pair includes a second linear guide rail and a second slider. The second linear guide rail is fixed to the base along a first horizontal direction, and the second slider is fixed to the carrier and slidably sleeved on the second linear guide rail.

[0024] Alternatively, the second linear guide rail extends along the first horizontal direction and is fixed to the carrier, and the second slider is fixed to the base and slidably sleeved on the second linear guide rail.

[0025] By setting up two carriers, two installation methods are provided that allow the two carriers to move closer or further apart along the first horizontal direction, which can meet two different application scenarios; at the same time, by setting a second sliding guide pair between the carrier and the base, the stability of the carrier moving along the first horizontal direction is improved.

[0026] Optionally, the first drive assembly includes two first drive components, each corresponding to a carrier component, with the drive end of the first drive component connected to the corresponding carrier component, wherein:

[0027] The first driving component includes a first motor, a first lead screw, and a first lead screw nut. The first lead screw is rotatable along its own axis and extended along a first horizontal direction and is mounted on a base. The first lead screw nut is rotatably sleeved on the first lead screw and fixedly connected to the corresponding bearing component.

[0028] The fixed end of the first motor is mounted on the base, and the rotating shaft of the first motor is connected to the first lead screw. The first motor is configured to drive the first lead screw to rotate along its own axis, so as to drive the corresponding bearing member to reciprocate along the first horizontal direction through the first lead screw nut.

[0029] By setting two first driving components, each corresponding to a carrier component, the separate driving control of the two carrier components is realized; through the cooperation of the first motor, the first lead screw and the first lead screw nut with the carrier component, the corresponding carrier component is driven to reciprocate along the first horizontal direction, thus providing a first driving component with high driving accuracy, high driving efficiency and long service life.

[0030] Optionally, each transverse component can be mounted on the base in a reciprocating manner along a second horizontal direction;

[0031] Alternatively, one of the transverse moving parts is fixedly mounted on the base, and the other transverse moving part is mounted on the base and can reciprocate along the second horizontal direction;

[0032] The transverse sliding member is mounted on the base and can reciprocate along the second horizontal direction. A third sliding guide pair is provided between the transverse sliding member and the base, wherein:

[0033] The third sliding guide pair includes a third linear guide rail and a third slider. The third linear guide rail is fixed on the base along the second horizontal direction, and the third slider is fixed on the transverse member and slidably sleeved on the third linear guide rail.

[0034] Alternatively, the third linear guide rail extends along the first horizontal direction and is fixed to the transverse member, and the third slider is fixed to the base and slidably sleeved on the third linear guide rail.

[0035] By setting up two transverse sliding members, two installation methods are provided that allow the two transverse sliding members to move closer or further apart along the second horizontal direction, which can meet two different application scenarios; at the same time, by setting a third sliding guide pair between the transverse sliding member and the base, the stability of the transverse sliding member moving along the second horizontal direction is improved.

[0036] Optionally, the second drive assembly includes two second drive components, each corresponding to a lateral movement component, with the drive end of the second drive component connected to the corresponding lateral movement component, wherein:

[0037] The second driving component includes a second motor, a first pulley, a second pulley, a transmission belt, a second lead screw, and a second lead screw nut. The second lead screw is rotatable along its own axis and is mounted on the base extending in the second horizontal direction. The second lead screw nut is rotatably sleeved on the second lead screw and is fixedly connected to the corresponding transverse component.

[0038] The fixed end of the second motor is mounted on the base. The rotating shaft of the second motor is coaxially connected to the first pulley. The second pulley is coaxially connected to the second lead screw. The transmission belt is sleeved on the first pulley and the second pulley.

[0039] The second motor is configured to drive the first pulley to rotate, thereby driving the second pulley to rotate via the transmission belt, which in turn drives the second lead screw to rotate along its own axis, thereby driving the corresponding transverse component to reciprocate along the second horizontal direction via the second lead screw nut.

[0040] By setting two second driving components, each corresponding to a transverse component, separate driving control of the two transverse components is achieved. Through the cooperation of the second motor, the first pulley, the second pulley, and the transmission belt, the second lead screw is driven to rotate along its own axis. Through the cooperation of the second lead screw and the second lead screw nut, the transverse component is driven to reciprocate along the second horizontal direction. This provides a second driving component with high driving accuracy, high driving efficiency, and long service life. At the same time, the use of a synchronous belt and lead screw transmission form allows the second motor to be located completely above or below the base, making reasonable use of the space above and below the base, avoiding the second motor from exceeding the base in the horizontal direction, reducing the space occupied by the second driving component, and thus saving workshop space.

[0041] Optionally, a support member is provided on the top surface of the carrier member, the support member being configured to support a row of battery cells extending along a second horizontal direction, such that the row of battery cells is suspended on both sides along the second horizontal direction.

[0042] By setting up support components, a row of battery cells is suspended on both sides along the second horizontal direction, which facilitates the subsequent bundling with steel straps.

[0043] A battery cell module extrusion assembly device includes a base, a support section, and an extrusion section, wherein:

[0044] The carrier includes two carrier members, which are spaced apart and slidably mounted on the base along a first horizontal direction. Each carrier member is configured to carry a row of battery cells extending along a second horizontal direction, which is perpendicular to the second horizontal direction.

[0045] The extrusion section includes a third drive assembly and two transverse members. The two transverse members are slidably mounted on the base along the second horizontal direction and are arranged opposite each other on the outer sides of the bearing section in the second horizontal direction. Each transverse member has two extrusion plates slidably mounted along the first horizontal direction on the side near the bearing section. Each extrusion plate corresponds to one row of battery cells. The drive end of the third drive assembly is connected to at least one transverse member. The third drive assembly is configured to drive the two transverse members to move closer or further away from each other along the second horizontal direction. The third drive assembly drives the two transverse members to move closer to each other, so that the two extrusion plates on each transverse member abut against one end of the two rows of battery cells carried on the two bearing members in the second horizontal direction, thereby synchronously extruding the two rows of battery cells in the second horizontal direction.

[0046] Each transverse component also includes a double-headed cylinder that drives the two extrusion plates to move closer or further apart. After the extrusion section performs synchronous extrusion on the two rows of cells in the second horizontal direction, the double-headed cylinder drives the two carriers to move closer together to merge the two rows of cells carried on the two carriers in the first horizontal direction.

[0057] Battery cell 40. Detailed Implementation

[0058] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] A battery cell module consists of multiple battery cells, end plates at both ends, and steel strips. If the battery cell module is made up of two rows of battery cells, the battery cells are usually first assembled into two rows of battery cells. Then, the two rows of battery cells are merged along the width direction by a battery cell module extrusion assembly device. The two rows of battery cells are fixed together by adhesive strips. The battery cell module extrusion assembly device then attaches the end plates to the battery cell module along the length direction of the two rows of battery cells. The battery cell module extrusion assembly device then extrudes the battery cell module to facilitate the subsequent application of steel strips.

[0060] However, in actual production, the existing battery cell module extrusion assembly device first merges two rows of battery cells along the width direction. Because there is an adhesive strip between the two rows of battery cells, the position of the two rows of battery cells along the length direction cannot be adjusted. If the two rows of battery cells are not aligned in the length direction, they can only be reassembled.

[0061] Example 1

[0062] Therefore, this application provides a battery cell module extrusion assembly device. Please refer to [link to relevant documentation]. Figure 1 As shown, the battery cell module extrusion assembly device provided in this application embodiment includes a base 10, a support part 20, and an extrusion part 30. The support part 20 includes a first drive assembly 21 and two support members 22, which are arranged along a first horizontal direction ( Figure 1 Each carrier member 22 is slidably mounted on the base 10 at intervals in the X direction, and each carrier member 22 is configured to bear loads along the second horizontal direction (in the X direction). Figure 1A row of battery cells 40 extending in the Y direction (in the first horizontal direction) is perpendicular to the second horizontal direction. At least one carrier member 22 is connected to the driving end of the first driving assembly 21. The first driving assembly 21 is configured to drive two carrier members 22 to move closer or further apart from each other along the first horizontal direction. The extrusion section 30 includes a second driving assembly 31 and two transverse members 32. The two transverse members 32 are slidably mounted on the base 10 along the second horizontal direction and are arranged opposite each other on the outer sides of the carrier section 20 at both ends in the second horizontal direction. Two extrusion plates 33 are slidably mounted on the side of each transverse member 32 near the carrier section 20 along the first horizontal direction. Each extrusion plate 33 corresponds to one row of battery cells 40. The second driving assembly 31... At least one transverse member 32 is connected to the drive end. The second drive assembly 31 is configured to drive the two transverse members 32 to move closer or further apart from each other in the second horizontal direction. The second drive assembly 31 drives the two transverse members 32 to move closer to each other, so that the two extrusion plates 33 on each transverse member 32 abut against one end of the two rows of battery cells 40 carried on the two carrier members 22 in the second horizontal direction, thereby performing synchronous extrusion on the two rows of battery cells 40 in the second horizontal direction. After the extrusion part 30 performs synchronous extrusion on the two rows of battery cells 40 in the second horizontal direction, the first drive assembly 21 drives the two carrier members 22 to move closer to each other, so as to merge the two rows of battery cells 40 carried on the two carrier members 22 in the first horizontal direction.

[0063] The battery cell module extrusion assembly device proposed in this application has two extrusion plates 33 on each of the two transverse members 32, and each extrusion plate 33 corresponds to a row of battery cells 40. The second drive assembly 31 cooperates with the two transverse members 32 to first extrude the two ends of the two rows of battery cells 40 in the second horizontal direction (the length direction of the two rows of battery cells 40), and then merges the two rows of battery cells 40 in the first horizontal direction (the width direction of the two rows of battery cells 40) through the cooperation of the first drive assembly 21 and the two carrier members 22, ensuring that the two rows of battery cells 40 are aligned in the length direction after assembly, thereby improving the assembly quality of the two rows of battery cells 40.

[0064] Please see Figures 1 to 3 As shown, in one embodiment, a reset elastic member 34 is provided between the two extrusion plates 33. The first end of the reset elastic member 34 is connected to one of the extrusion plates 33, and the second end of the reset elastic member 34 is connected to the other extrusion plate 33. The reset elastic member 34 is configured to push the two extrusion plates 33 away from the corresponding column of cells after the two extrusion plates 33 leave the corresponding column of cells.

[0065] Specifically, the reset elastic element 34 is a spring. After the extrusion section 30 synchronously extrudes the two rows of cells 40 in the second horizontal direction, the first drive assembly 21 drives the two carriers 22 to move closer to each other, thereby driving the two extrusion plates 33 to move closer to each other. The reset elastic element 34 is compressed. When the two extrusion plates 33 leave the corresponding row of cells 40, the reset elastic element 34 pushes the two extrusion plates 33 away and resets them through its own elastic force.

[0066] As can be seen, by setting a reset elastic element 34 between the two extrusion plates 33, the two extrusion plates 33 can automatically reset after the two rows of cells 40 are extruded in the second horizontal direction, which facilitates the assembly of the next set of two rows of cells 40.

[0067] In one embodiment, both extrusion plates 33 can be reciprocatedly mounted on the transverse member 32 in the first horizontal direction; or, one extrusion plate 33 can be fixedly mounted on the transverse member 32, and the other extrusion plate 33 can be reciprocatedly mounted on the transverse member 32 in the first horizontal direction.

[0068] It can be seen that by setting the two extrusion plates 33, two installation forms of the extrusion plates 33 are provided, which can make the two extrusion plates 33 follow the two rows of cells 40 and move closer or further away from each other along the first horizontal direction, thus meeting two different application scenarios.

[0069] In one embodiment, the extrusion plate 33 is reciprocally mounted on the transverse member 32 along a first horizontal direction. A first sliding guide pair 35 is provided between the extrusion plate 33 and the transverse member 32. The first sliding guide pair 35 includes a first linear guide rail 350 and a first slider 351. The first linear guide rail 350 is fixed to the transverse member 32 along the first horizontal direction, and the first slider 351 is fixed to the extrusion plate 33 and slidably sleeved on the first linear guide rail 350. Alternatively, the first linear guide rail 350 is fixed to the extrusion plate 33 along the first horizontal direction, and the first slider 351 is fixed to the transverse member 32 and slidably sleeved on the first linear guide rail 350.

[0070] It can be seen that the first sliding guide pair 35 is provided between the extrusion plate 33 and the transverse moving member 32, which improves the stability of the extrusion plate 33 reciprocating along the first horizontal direction.

[0071] Please see Figure 4 and Figure 5 As shown, in one embodiment, each carrier 22 is reciprocally mounted on the base 10 in a first horizontal direction; or, one carrier 22 is fixedly mounted on the base 10, and the other carrier 22 is reciprocally mounted on the base 10 in a first horizontal direction.

[0072] It can be seen that by setting the two carriers 22, two installation methods are provided that enable the two carriers 22 to move closer or further apart along the first horizontal direction, which can meet two different application scenarios.

[0073] In one embodiment, the carrier 22 is reciprocally mounted on the base 10 along a first horizontal direction. A second sliding guide pair 23 is provided between the carrier 22 and the base 10. The second sliding guide pair 23 includes a second linear guide rail 230 and a second slider 231. The second linear guide rail 230 is fixed to the base 10 along the first horizontal direction, and the second slider 231 is fixed to the carrier 22 and slidably sleeved on the second linear guide rail 230. Alternatively, the second linear guide rail 230 is fixed to the carrier 22 along the first horizontal direction, and the second slider 231 is fixed to the base 10 and slidably sleeved on the second linear guide rail 230.

[0074] It can be seen that by setting a second sliding guide pair 23 between the carrier 22 and the base 10, the stability of the carrier 22 moving along the first horizontal direction is improved.

[0075] In one embodiment, the first drive assembly 21 includes two first drive members 210, each first drive member 210 corresponding to a carrier member 22. The drive end of the first drive member 210 is connected to the corresponding carrier member 22. The first drive member 210 includes a first motor 2100, a first lead screw 2101, and a first lead screw nut 2102. The first lead screw 2101 is rotatable along its own axis and extended along a first horizontal direction and is mounted on the base 10. The first lead screw nut 2102 is rotatably sleeved on the first lead screw 2101 and fixedly connected to the corresponding carrier member 22. The fixed end of the first motor 2100 is mounted on the base 10. The rotating shaft of the first motor 2100 is connected to the first lead screw 2101. The first motor 2100 is configured to drive the first lead screw 2101 to rotate along its own axis, so as to drive the corresponding carrier member 22 to reciprocate along the first horizontal direction through the first lead screw nut 2102.

[0076] As can be seen, by setting two first driving components 210, each first driving component 210 corresponding to a carrier component 22, the two carrier components 22 can be driven and controlled separately. Through the cooperation of the first motor 2100, the first lead screw 2101 and the first lead screw nut 2102 and the carrier component 22, the corresponding carrier component 22 is driven to reciprocate along the first horizontal direction, providing a first driving component 210 with high driving accuracy, high driving efficiency and long service life.

[0077] Please see Figure 1 and Figure 2As shown, in one embodiment, each transverse member 32 is reciprocally mounted on the base 10 in a second horizontal direction; or, one transverse member 32 is fixedly mounted on the base 10, and the other transverse member 32 is reciprocally mounted on the base 10 in a second horizontal direction.

[0078] It can be seen that by setting the two transverse moving parts 32, two installation methods are provided to enable the two transverse moving parts 32 to move closer or further apart along the second horizontal direction, which can meet two different application scenarios.

[0079] In one embodiment, the transverse member 32 is reciprocally mounted on the base 10 along the second horizontal direction. A third sliding guide pair 36 is provided between the transverse member 32 and the base 10. The third sliding guide pair 36 includes a third linear guide rail 360 and a third slider 361. The third linear guide rail 360 is fixed to the base 10 along the second horizontal direction, and the third slider 361 is fixed to the transverse member 32 and slidably sleeved on the third linear guide rail 360. Alternatively, the third linear guide rail 360 is fixed to the transverse member 32 along the first horizontal direction, and the third slider 361 is fixed to the base 10 and slidably sleeved on the third linear guide rail 360.

[0080] It can be seen that by setting a third sliding guide pair 36 between the transverse member 32 and the base 10, the smoothness of the transverse member 32 moving along the second horizontal direction is improved.

[0081] In one embodiment, the second drive assembly 31 includes two second drive members 310, each second drive member 310 corresponding to a transverse member 32. The drive end of the second drive member 310 is connected to the corresponding transverse member 32. The second drive member 310 includes a second motor 3100, a first pulley 3101, a second pulley 3102, a transmission belt 3103, a second lead screw 3104, and a second lead screw nut 3105. The second lead screw 3104 is rotatable along its own axis and extended along a second horizontal direction on the base 10. The second lead screw nut 3105 is rotatably sleeved on the second lead screw 3104 and is connected to the corresponding transverse member 32. The moving part 32 is fixedly connected; the fixed end of the second motor 3100 is mounted on the base 10, the shaft of the second motor 3100 is coaxially connected to the first pulley 3101, the second pulley 3102 is coaxially connected to the second lead screw 3104, and the transmission belt 3103 is sleeved on the first pulley 3101 and the second pulley 3102; the second motor 3100 is configured to drive the first pulley 3101 to rotate, so as to drive the second pulley 3102 to rotate through the transmission belt 3103, and then drive the second lead screw 3104 to rotate along its own axis, so as to drive the corresponding transverse moving part 32 to reciprocate along the second horizontal direction through the second lead screw nut 3105.

[0082] Specifically, the first pulley 3101 and the second pulley 3102 are synchronous pulleys, and the transmission belt 3103 is a synchronous belt.

[0083] Specifically, the second motor 3100 is located directly below the base 10.

[0084] As can be seen, by setting two second driving components 310, each corresponding to a transverse component 32, the two transverse components 32 can be driven and controlled independently. Through the cooperation of the second motor 3100, the first pulley 3101, the second pulley 3102 and the transmission belt 3103, the second lead screw 3104 is driven to rotate along its own axis. Through the cooperation of the second lead screw 3104 and the second lead screw nut 3105, the transverse component 32 is driven to reciprocate along the second horizontal direction. This provides a second driving component 310 with high driving accuracy, high driving efficiency and long service life. At the same time, the transmission form of synchronous belt and lead screw is adopted, so that the second motor 3100 is completely located above or below the base 10, making reasonable use of the space above and below the base 10, avoiding the second motor 3100 from exceeding the base 10 in the horizontal direction, reducing the space occupied by the second driving component 310, and thus saving workshop space.

[0085] Please see Figure 5 As shown, in one embodiment, a support member 37 is provided on the top surface of the carrier 22. The support member 37 is configured to support a row of battery cells 40 extending along the second horizontal direction, so that the row of battery cells 40 is suspended on both sides along the second horizontal direction.

[0086] Specifically, the support member 37 includes two sleepers, which are arranged parallel to each other along a first horizontal direction and extended along a second horizontal direction and installed on the top surface of the bearing member 22.

[0087] As can be seen, by setting the support member 37, a row of battery cells 40 is suspended on both sides along the second horizontal direction, which facilitates the subsequent bundling with steel straps.

[0088] Please see Figure 4 As shown, Figure 4 The solid arrow in the image indicates the direction in which the two rows of battery cells 40 are synchronously compressed in the second horizontal direction. Figure 4 The dashed arrow in the figure indicates the direction in which the two rows of battery cells 40 are merged in the first horizontal direction. The general working principle of the battery cell module extrusion and assembly device proposed in this application embodiment is as follows:

[0089] S1, the two rows of battery cells 40 are respectively placed on two carriers 22;

[0090] S2, the second drive assembly 31 drives the two transverse members 32 to move closer to each other, so that the two extrusion plates 33 on each transverse member 32 respectively abut against one end of the two rows of battery cells 40 carried on the two carrier members 22 in the second horizontal direction, thereby synchronously extruding the two rows of battery cells 40 in the second horizontal direction.

[0091] S3, the first drive assembly 21 drives the two carriers 22 to move closer to each other so as to merge the two rows of cells 40 carried on the two carriers 22 in the first horizontal direction.

[0092] The battery cell module extrusion assembly device proposed in this application has the following advantages:

[0093] 1) The assembly method of first squeezing the two rows of cells in the second horizontal direction and then merging the two rows of cells in the first horizontal direction ensures that the two rows of cells are aligned in the length direction after assembly, thus improving the assembly quality of the two rows of cells.

[0094] 2) It is equipped with a reset elastic element, and the two pressing plates can automatically reset, which facilitates the assembly of the next two rows of cells;

[0095] 3) The first and second drive components have high drive precision, high drive efficiency and long service life.

[0096] 4) The carrier is equipped with a support, which allows each row of cells to be suspended on both sides along the second horizontal direction, making it convenient for subsequent assembly and bundling with steel straps.

[0097] Example 2

[0098] Please see Figure 6As shown in Embodiment 2 of this application, a battery cell module extrusion assembly device is proposed, which includes a base 10, a support portion 20, and an extrusion portion 30. The support portion 20 includes two support members 22, which are spaced apart and slidably mounted on the base 10 along a first horizontal direction. Each support member 22 is configured to support a row of battery cells 40 extending along a second horizontal direction, the first horizontal direction being perpendicular to the second horizontal direction. The extrusion portion 30 includes a third drive assembly 38 and two transverse members 32, which are slidably mounted on the base 10 along the second horizontal direction and are positioned opposite each other on the outer sides of the support portion 20 in the second horizontal direction. Each transverse member 32 has two extrusion plates 33 slidably mounted along the first horizontal direction on the side closest to the support portion 20. Each extrusion plate 33 corresponds to a row of battery cells 40. The drive end of the three-drive assembly 38 is connected to at least one transverse member 32. The third drive assembly 38 is configured to drive the two transverse members 32 to move closer or further away from each other in the second horizontal direction. The third drive assembly 38 drives the two transverse members 32 to move closer to each other, so that the two extrusion plates 33 on each transverse member 32 respectively abut against one end of the two rows of battery cells 40 carried on the two carrier members 22 in the second horizontal direction, thereby performing synchronous extrusion on the two rows of battery cells 40 in the second horizontal direction. Each transverse member 32 also includes a double-headed cylinder 39 that drives the two extrusion plates 33 to move closer or further away from each other. After the extrusion section 30 performs synchronous extrusion on the two rows of battery cells 40 in the second horizontal direction, the double-headed cylinder 39 drives the two carrier members 22 to move closer to each other, so as to merge the two rows of battery cells 40 carried on the two carrier members 22 in the first horizontal direction.

[0099] It should be noted that the main difference between this embodiment and Embodiment 1 is that in this embodiment, the two support members 22 of the support section 20 are not equipped with drive components. Instead, the transverse member 32 is equipped with a double-headed cylinder 39 that drives the two extrusion plates 33 to move closer or further apart. After the extrusion section 30 synchronously extrudes the two rows of battery cells 40 in the second horizontal direction, the double-headed cylinder 39 drives the two extrusion plates 33 to move closer together, thereby causing the two rows of battery cells 40 carried on the two support members 22 to merge in the first horizontal direction. Other structures are the same and will not be described again here.

[0100] The battery cell module extrusion assembly device proposed in this application has two extrusion plates 33 on each of the two transverse members 32. Each extrusion plate 33 corresponds to a row of battery cells 40. The third drive assembly 38 cooperates with the two transverse members 32 to first extrude the two ends of the two rows of battery cells 40 in the second horizontal direction (the length direction of the two rows of battery cells 40). Then, the two extrusion plates 33 are driven to move closer to each other by the double-headed cylinder 39, thereby driving the two rows of battery cells 40 on the two carrier members 22 to merge in the first horizontal direction (the width direction of the two rows of battery cells 40), ensuring that the two rows of battery cells 40 are aligned in the length direction after assembly, and improving the assembly quality of the two rows of battery cells 40.

[0101] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
