During the process of installing the seal, multiple sucking and installation operations are required, which takes a long time and leads to low efficiency of the production line.

[0005] Summary of the Invention

[0006] The main purpose of the embodiments of the present application is to provide a seal installation control method and system, which aims to solve the technical problem that the installation of the seal of the battery cell liquid injection port takes a long time and leads to low production line efficiency.

[0009] This embodiment adjusts the component spacing between each suction component according to the position of the liquid injection port of each battery cell on the installation station, so that each suction component used to absorb the seal corresponds to the liquid injection port of each battery cell, and controls each suction component after adjusting the component spacing to install the absorbed seal to the liquid injection port of the corresponding battery cell on the installation station. By adjusting the component spacing between the suction components so that each suction component corresponds to the liquid injection port of each battery cell, and controlling each suction component to install the absorbed seal to the liquid injection port of the corresponding battery cell, multiple seals can be installed at one time, which shortens the time for seal installation and improves production line efficiency.

[0011] This embodiment controls each suction component to move to a preset installation position after adjusting the component spacing, and when each suction component moves to the preset installation position after adjusting the component spacing, controls each suction component to install the respectively sucked sealant to the liquid injection port of the corresponding battery cell on the installation station. By controlling each suction component that has sucked the sealant to install the sucked sealant to the liquid injection port of the corresponding battery cell, the time for installing the sealant is saved and the production line efficiency is improved.

[0012] In some embodiments, the control of adjusting the spacing between components and installing the sucked seals to the liquid injection port of the corresponding battery cell on the installation station includes: controlling the suction components to move to a preset loading position after adjusting the spacing, and controlling the suction components at the preset loading position to suck the seals; when the suction components suck the seals, controlling the suction components to move to a preset installation position; controlling the suction components at the preset installation position to install the sucked seals to the liquid injection port of the corresponding battery cell on the installation station.

[0067] Currently, the process of installing seals typically involves controlling a loading robot to repeatedly pick up seals, while a visual positioning device takes photos to locate them. Once the positioning is complete, the loading robot is controlled to move and install the seals one by one into the battery cell's injection port according to the injection port position obtained by positioning. This process requires controlling the loading robot to repeatedly pick up seals, and only one seal can be installed into the battery cell's injection port at a time. If a large number of battery cells require seal installation, this process can be time-consuming and lead to low production line efficiency. Therefore, improving seal installation efficiency has become a pressing technical issue.

[0068] In order to solve the above technical problems, an embodiment of the present application proposes a seal installation control method and system, which obtains the position of the liquid injection port of each battery cell on the installation station, and adjusts the component spacing between each suction component used to absorb the seal according to the position of the liquid injection port of each battery cell, so that each suction component after adjusting the component spacing corresponds to the liquid injection port of each battery cell, and controls each suction component after adjusting the component spacing to install the absorbed seal to the liquid injection port of the corresponding battery cell.

[0069] In a first aspect, an embodiment of the present application provides a seal installation control method. Referring to FIG. 1 , FIG. 1 is a flow chart of an embodiment of the seal installation control method of the present application.

[0070] In this embodiment, the seal installation control method includes the following steps:

[0071] Step S1: Obtain the position of the liquid injection port of each battery cell on the installation station.

[0072] The installation station may be a station for placing the battery cell installation seal. The liquid injection port may be an opening provided on the battery cell for injecting electrolyte. The liquid injection port position may be the spatial location of the liquid injection port.

[0073] Step S2: adjusting the component spacing between the suction components according to the position of the liquid injection port so that the suction components correspond to the liquid injection port of each battery cell, and the suction components are used to absorb the sealing member.

[0074] The suction assembly may be an assembly for sucking the sealing member. The assembly spacing may be the distance between each suction assembly. The sealing member may be an assembly for sealing the liquid injection port of the battery cell.

[0075] Step S3: After adjusting the spacing between components, each suction component is controlled to install the sucked seal to the liquid injection port of the corresponding battery cell on the installation station.

[0076] In one example, a controller uses a positioning device to determine the location of the liquid injection port of each battery cell placed at the installation station. Based on the location of the liquid injection port, the controller controls the movement of each suction assembly, thereby adjusting the spacing between the suction assemblies so that each suction assembly, after the adjusted spacing, corresponds to the liquid injection port of each battery cell. The controller then controls each suction assembly to install the suctioned sealant into the corresponding battery cell's liquid injection port.

[0077] In another example, referring to FIG2 , FIG2 is a schematic diagram of installing a seal. If four battery cells 10 are placed on the installation station 100 and are represented as D1, D2, D3 and D4 respectively, the liquid injection ports 101 of the four battery cells 10 are positioned by a positioning device, and the positions of the liquid injection ports 101 of the four battery cells 10 are obtained as S1, S2, S3 and S4 respectively. Assuming that there are four suction components 20X1, X2, X3 and X4, the controller controls X1 to move according to S1, controls X2 to move according to S2, controls X3 to move according to S3, and controls X4 to move according to S4, so that the moved suction components 20 correspond to the liquid injection ports 101 of D1, D2, D3, and D4 respectively. The controller controls each suction component 20 to move to a preset installation position, and controls X1 to install the sucked seal 30 to the liquid injection port 101 of D1, controls X2 to install the sucked seal 30 to the liquid injection port 101 of D2, controls X3 to install the sucked seal 30 to the liquid injection port 101 of D3, and controls X4 to install the sucked seal 30 to the liquid injection port 101 of D4; the number of suction components 20 can be set according to the specific scenario, for example, set to 5, 6, 8, etc., and this embodiment is not limited here.

[0078] This embodiment adjusts the component spacing between each suction component 20 according to the position of the liquid injection port 101 of each battery cell 10 on the installation station 100, so that each suction component 20 for sucking the seal 30 corresponds to the liquid injection port 101 of each battery cell 10, and controls each suction component 20 after adjusting the component spacing to install the sucked seal 30 to the liquid injection port 101 of the corresponding battery cell 10 on the installation station 100. By adjusting the component spacing between the suction components 20 so that each suction component 20 corresponds to the liquid injection port 101 of each battery cell 10, and controlling each suction component 20 to install the sucked seal 30 to the liquid injection port 101 of the corresponding battery cell 10, multiple seals 30 can be installed at one time, which shortens the time for installing the seal 30 and improves the production line efficiency.

[0079] In some embodiments, referring to FIG. 3 , step S3 includes:

[0080] Step S31: Controlling each suction component after adjusting the component spacing to move to a preset installation position.

[0081] The preset installation position may be a preset position for installing the sealing member on the liquid filling port.

[0082] As an implementation method, each suction component is set on a manipulator, and the component spacing between each suction component set on the manipulator is adjusted according to the position of each liquid injection port, so that each suction component corresponds to the liquid injection port of the corresponding battery cell, and the manipulator is controlled to move to a preset installation position. After the manipulator moves to the preset installation position, each suction component corresponds to the liquid injection port of the battery cell.

[0083] Step S32: When each suction component moves to the preset installation position, each suction component is controlled to install the sealant sucked by it to the liquid injection port of the corresponding battery cell on the installation station.

[0084] In an example, assuming that the seal is an aluminum nail, a suction component is provided on the manipulator, and the vibration plate nail feeding component sends the aluminum nail to the upper nail position through vibration displacement. The manipulator is controlled to move to the preset loading position, and the manipulator at the preset loading position is controlled to suck the aluminum nail at the upper nail position through the suction component, and the positioning device is used to position the injection port of each battery cell on the installation station to obtain the injection port position of each battery cell. The component spacing between each suction component on the manipulator is adjusted according to the injection port position of each battery cell, so that the adjusted component spacing corresponds to the spacing between the injection ports of each battery cell, and the manipulator is controlled to move to the preset installation position so that each suction component is above the injection port of the corresponding battery cell, and each suction component is controlled to install the sucked aluminum nail to the injection port of each battery cell.

[0085] In another example, referring to FIG4 , FIG4 is a schematic diagram of adjusting the spacing between components. Assuming that three battery cells 10 are placed on the installation station 100, respectively represented as D11, D12 and D13, there are four suction components 20X1, X2, X3 and X4. The injection ports 101 of the three battery cells 10 are positioned by the visual positioning device. The coordinates of the injection ports 101 obtained are: (a1, b1, c1), (a2, b2, c2) and (a3, b3, c3), respectively. Then, the spacing adjustment component is controlled to drive X1 to move. Move to the preset position, drive X2 to move so that the distance between X2 and X1 is adjusted to (b2-b1), drive X3 to move so that the distance between X3 and X2 is adjusted to (b3-b2), and after adjusting the spacing, X1, X2 and X3 correspond to D11, D12 and D13 respectively. Control X1 to install the sucked seal 30 to the liquid injection port 101 of D11, control X2 to install the sucked seal 30 to the liquid injection port 101 of D12, and control X3 to install the sucked seal 30 to the liquid injection port 101 of D13.

[0086] In the embodiment of the present application, each suction component 20 is controlled to move to a preset installation position after adjusting the component spacing, and when each suction component 20 is moved to the preset installation position after adjusting the component spacing, each suction component 20 is controlled to install the respectively sucked seal 30 to the liquid injection port 101 of the corresponding battery cell 10 on the installation station 100. By controlling each suction component 20 that has sucked the seal 30 to install the sucked sealant to the liquid injection port 101 of the corresponding battery cell 10, the installation time of the seal 30 is saved and the production line efficiency is improved.

[0087] In some embodiments, referring to FIG. 5 , step S3 further includes:

[0088] Step S311: Controlling each suction component after adjusting the spacing to move to a preset loading position, and controlling each suction component at the preset loading position to suck the sealing member.

[0089] The preset loading position may be a preset position where the suction component sucks the sealing member.

[0090] As an implementation method, each suction component is set on a robot, and the robot is controlled to move to a preset loading position, thereby driving each suction component to move to the preset loading position.

[0091] Step S312: When each suction component sucks the seal, control each suction component to move to a preset installation position.

[0092] Step S313: controlling each suction assembly at a preset installation position to install the sucked seal to the liquid injection port of the corresponding battery cell on the installation station.

[0093] In an example, assuming that the seal is an aluminum nail, a suction component is provided on the manipulator, and the vibration disk nail feeding component sends the aluminum nail to the upper nail position through vibration displacement, and the positioning device is used to position the liquid injection port of each battery cell on the installation station to obtain the position of the liquid injection port of each battery cell, and the component spacing between the suction components on the manipulator is adjusted according to the position of the liquid injection port of each battery cell, so that the suction components after the component spacing is adjusted correspond to the liquid injection port of the battery cell, and the manipulator is controlled to drive the suction components after the component spacing is adjusted to move to the preset loading position, and control the suction components at the preset loading position to suck the seal, and when each suction component sucks the seal, the manipulator is controlled to drive each suction component that has sucked the seal 30 to move to the preset installation position, and each suction component at the preset installation position corresponds to the liquid injection port of each battery cell, and control each suction component to install the sucked seal to the liquid injection port of the corresponding battery cell.

[0094] In the embodiment of the present application, each suction component is controlled to move to a preset loading position after adjusting the component spacing, and each suction component at the preset loading position is controlled to suck the seal, and each suction component that sucks the seal is controlled to move to a preset installation position, and then each suction component at the preset installation position is controlled to install the sucked seal to the injection port of the corresponding battery cell on the installation station. By controlling each suction component to suck the seal after adjusting the component spacing, and controlling the suction component that has sucked the seal to move to the preset installation position to install the sucked seal to the injection port of the corresponding battery cell, there is no need to suck and install the seal multiple times, which shortens the installation time of the seal and improves the production line efficiency.

[0095] In some embodiments, adjusting the component spacing between the suction components according to the position of the liquid injection port includes:

[0096] The spacing adjustment component is controlled according to the position of the liquid injection port to drive each suction component to move, so as to adjust the component spacing between each suction component.

[0097] The spacing adjustment component may be a component used to adjust the distance between the suction components by driving the suction components to move.

[0098] In one example, for example, the number of spacing adjustment components is equal to the number of suction components, and the spacing adjustment components and the suction components are set correspondingly. The spacing adjustment components are controlled according to the position of the liquid injection port of each battery cell to drive the corresponding suction components to move, so as to adjust the component distance between each suction component, so that the distance between each suction component after the component distance is adjusted corresponds to the distance between the liquid injection ports of each battery cell.

[0099] In the embodiment of the present application, the spacing adjustment component is controlled according to the position of the liquid injection port of each battery cell to drive the movement of each suction component, thereby adjusting the component spacing between each suction component. The automatic adjustment of the component spacing is achieved through the spacing adjustment component, which improves the accuracy of the spacing adjustment and the efficiency of the component spacing adjustment.

[0100] In some embodiments, the spacing adjustment component is a spacing servo motor, and the servo motor is correspondingly arranged to each suction component, and each servo motor is used to adjust the position of the corresponding suction component.

[0101] The spacing servo motor is connected to each suction component through a screw rod, and the position of the suction component can be adjusted by controlling the operation of the spacing servo motor.

[0102] As an implementation method, each suction component is provided with a corresponding spacing servo motor, and the spacing servo motor is connected to the corresponding suction component through a screw rod. The position of the liquid injection port of each battery cell on the installation station is obtained through a positioning device, and the operation of the spacing servo motor is controlled according to the position of the liquid injection port of each battery cell to adjust the position of the corresponding suction component, so that the adjusted each suction component corresponds to the liquid injection port of each battery cell on the installation station, and each suction component is controlled to move to a preset installation position, and the suction component is controlled to install the sucked seal to the liquid injection port of the corresponding battery cell.

[0103] In an example, assuming that the seal is an aluminum nail, the suction component is a suction nozzle, the suction nozzle is set on a three-axis robot, and the visual positioning device is a CCD visual positioning device. The controller controls the vibration plate nail feeding component to send the aluminum nail to the upper nail position through vibration displacement, controls the CCD visual positioning device to locate the liquid injection port of each battery cell on the installation station, obtains the position of the liquid injection port of each battery cell, and controls the spacing servo motor to operate according to the position of the liquid injection port of each battery cell to adjust the nozzle spacing between each nozzle. After the nozzle spacing is adjusted, each nozzle corresponds to the liquid injection port of each battery cell, controls the robot to move to a preset loading position, and controls the Z axis of the robot to descend to the upper nail position to absorb the aluminum nail, wherein the aluminum nail can be sent to the upper nail position by controlling the vibration plate nail feeding component through vibration displacement. After the aluminum nail is absorbed, the Z axis of the robot is controlled to rise to the preset loading position, and the robot is controlled to move to the preset installation position. The Z axis of the robot at the preset installation position is controlled to descend to the preset nail placement position, and the negative pressure corresponding to each nozzle is controlled to be closed, so that the aluminum nail absorbed by each nozzle is installed at the liquid injection port of the corresponding battery cell.

[0104] In another example, referring to Figures 6(a) and 6(b), Figure 6(a) is a schematic diagram of the control spacing servo motor before adjusting the nozzle spacing, and Figure 6(b) is a schematic diagram of the control spacing servo motor after adjusting the nozzle spacing. Four spacing servo motors J1, J2, J3 and J4 are set on the manipulator, corresponding to the nozzles X1, X2, X3 and X4 respectively. Assume that there are four battery cells 10 placed on the installation station 100, namely D21, D22, D23 and D24, and the 101 coordinates of each battery cell 10 obtained by the visual positioning device are (x1, y1, z1), (x2, y2, z2), (x3, y3, z3) and (x4, y4, z4), respectively. Then according to (x1, y1, z1 ) controls J1 to adjust the coordinates of X1 to (x, y1, z), controls J2 to adjust the coordinates of X2 to (x, y2, z) according to (x2, y2, z2), controls J3 to adjust the coordinates of X3 to (x, y3, z) according to (x3, y3, z3), controls J4 to adjust the coordinates of X4 to (x, y4, z) according to (x4, y4, z4), the adjusted X1 corresponds to 101 of D21, the adjusted X2 corresponds to 101 of D22, the adjusted X3 corresponds to 101 of D23, the adjusted X4 corresponds to 101 of D24, controls X1, X2, X3 and X4 to install the sucked seal 30 to D21, D22, D23 and D24 respectively.

[0105] In the embodiment of the present application, the spacing adjustment component 40 is a servo motor, which is correspondingly provided to each suction component 20. The position of the corresponding suction component 20 is adjusted by each servo motor, thereby improving the accuracy of position adjustment of the suction component 20.

[0106] In some embodiments, referring to FIG. 7 , step S32 includes:

[0107] Step S321: When each suction component moves to the preset installation position, the negative pressure of each suction component is controlled to be closed, so as to install the sealing member sucked by each suction component to the liquid injection port of the battery cell corresponding to the installation station.

[0108] The suction assembly sucks the seal by negative pressure.

[0109] In one example, for example, the suction component is a suction nozzle, which is provided on a manipulator. The spacing servo is controlled to adjust the position of the corresponding suction nozzle according to the position of the liquid injection port of each battery cell, thereby adjusting the nozzle spacing between each suction nozzle. The manipulator is controlled to drive the suction nozzle after the nozzle spacing is adjusted to a preset installation position. When the manipulator drives the suction nozzle to the preset installation position, the negative pressure of each suction component is controlled to be closed, thereby installing the seal to the liquid injection port of the corresponding battery cell at the installation station.

[0110] In the embodiment of the present application, when each suction component is moved to a preset installation position, the negative pressure of each suction component is controlled to be closed, so that the seals sucked by each suction component are installed to the liquid injection port of the corresponding battery cell at the installation station, achieving the effect of installing multiple seals at one time and improving the installation efficiency of the seals.

[0111] In some embodiments, referring to FIG. 8 , step S313 includes:

[0112] Step S3131: closing the negative pressure corresponding to each suction assembly at the preset installation position, so as to install the sealing member sucked by each suction assembly to the liquid injection port of the corresponding battery cell on the installation station.

[0113] In one example, the robot is controlled to drive the suction nozzle to a preset loading position, and each suction nozzle at the preset loading position is controlled to suck the seal. When each suction nozzle sucks the seal, the robot is controlled to drive the suction nozzle to a preset installation position, and the negative pressure corresponding to each suction nozzle at the preset installation position is closed, so that each suction nozzle installs the seal it has sucked to the liquid filling port of the corresponding battery cell on the installation station.

[0114] In the embodiment of the present application, the negative pressure of each suction component in the preset installation position is closed, so that each suction component can install the seal it has sucked into the liquid injection port of the corresponding battery cell on the installation station. The seals can be installed at the liquid injection ports of multiple battery cells at the same time, thereby improving the installation efficiency of the seals.

[0115] In some embodiments, controlling each suction assembly after adjusting the spacing to move to a preset loading position, and controlling each suction assembly at the preset loading position to suck the seal comprises:

[0116] The suction components after adjusting the spacing are controlled to move to the preset feeding position, and the suction components at the preset feeding position are controlled to descend to the upper nail position to absorb the sealing member, and the sealing member is located at the upper nail position.

[0117] This embodiment controls the vibrating plate nail feeding assembly to deliver the seal to the upper nailing position through vibration displacement, and the seal is located at the upper nailing position. The suction assemblies after adjusting the spacing are controlled to move to the preset loading position. Thereafter, the suction assemblies at the preset loading position are controlled to descend to the upper nailing position to absorb the seal, so that each suction assembly can absorb the seal after descending to the upper nailing position at the preset loading position.

[0118] In one example, the controller controls the robot to drive the suction nozzle to move to a preset loading position, then controls the robot to drive the suction nozzle down to the upper nail position, and controls each suction nozzle at the upper nail position to suck the seal.

[0119] In some embodiments, referring to FIG. 9 , step S1 includes:

[0120] Step S11: positioning the liquid injection port of each battery cell on the installation station by using a visual positioning device, and obtaining the position of the liquid injection port of each battery cell obtained by the visual positioning device.

[0121] The visual positioning device can be a device that converts the detected object into an image signal and performs positioning based on the image signal. For example, the visual positioning device includes but is not limited to a CCD camera (charge coupled device camera), a 3D visual positioning device, etc.

[0122] In an example, for example, the position of the liquid injection port is the liquid injection port coordinate, and the controller controls the CCD camera to locate the liquid injection port of each battery cell on the installation station to obtain the liquid injection port coordinate of each battery cell.

[0123] In the embodiment of the present application, the liquid injection port of each battery cell on the installation station is positioned by a visual positioning device, and the position of the liquid injection port of each battery cell obtained by positioning is obtained. The liquid injection port of each battery cell is positioned by the visual positioning device, thereby improving the positioning accuracy of the battery cell liquid injection port.

[0124] In some embodiments, referring to FIG. 10 , step S1 further includes:

[0125] Step S111: positioning the liquid injection port of each battery cell on the installation station by a visual positioning device, and storing the liquid injection port position of each battery cell liquid injection port obtained by the visual positioning device in a target storage area.

[0126] The target storage area may be a pre-set storage area for storing the position of the liquid injection port.

[0127] Step S112: obtaining the position of the liquid injection port of each battery cell stored in the target storage area.

[0128] In one example, for example, if the controller is a programmable logic controller (PLC), the target storage area inside the PLC for storing the coordinates of the liquid injection port is marked by a label address. The PLC controls the visual positioning device to locate the liquid injection port of each battery cell on the installation station, obtains the coordinates of the liquid injection port of each battery cell, and stores the liquid injection port coordinates sent by the visual positioning device in the storage area corresponding to the label address. The PLC reads the coordinates of the liquid injection port of each battery cell from the storage area corresponding to the label address.

[0129] 13 , each suction assembly 20 is disposed on a three-axis robot 200 , and the spacing adjustment assembly 40 is also disposed on the three-axis robot 200 . The three-axis robot 200 includes an X-axis 201 , a Y-axis 202 , and a Z-axis 203 .

[0130] For example, the seal is an aluminum nail, the visual positioning device is a CCD visual positioning device, the suction component 20 is a vacuum suction nozzle, the spacing adjustment component 40 is a spacing servo motor, and the vacuum suction nozzle is arranged on the three-axis manipulator 200. The three-axis manipulator 200 includes an X-axis 201, a Y-axis 202 and a Z-axis 203, and each vacuum suction nozzle is correspondingly provided with a spacing servo motor, which controls the vibration plate to send the aluminum nail component to the upper nail position (i.e., the preset loading position) through vibration displacement. After the three-axis manipulator 200 is controlled to reach the preset loading position, the Z-axis 203 of the three-axis manipulator 200 is controlled to descend to the preset suction position, and the negative pressure corresponding to each vacuum suction nozzle is controlled to open to absorb the aluminum nail. After the nail absorption is completed, the Z-axis 203 of the three-axis manipulator 200 is controlled to rise to the preset loading position, and the injection port of each battery cell on the installation station is positioned by controlling the CCD visual positioning device to obtain the injection port coordinates of each injection port, and The liquid injection port coordinates sent by the CCD visual positioning device are received through the EIP protocol, and the received coordinates of each liquid injection port are stored in a preset storage area corresponding to the label address, the three-axis manipulator 200 is controlled to move to the preset installation position, and the spacing servo motor is controlled to adjust the spacing between each vacuum suction nozzle according to the liquid injection port coordinates read from the preset storage area, so that the vacuum suction nozzles after adjusting the spacing correspond to the liquid injection port of the battery cell. If the three-axis manipulator 200 reaches the preset installation position and the spacing adjustment between the suction nozzles is completed, the Z-axis 203 of the three-axis manipulator 200 is controlled to descend to the aluminum nail placement position. If the Z-axis 203 of the three-axis manipulator 200 descends to the aluminum nail placement position, the negative pressure corresponding to each vacuum suction nozzle is controlled to be closed, so that the aluminum nail sucked by the suction nozzle is installed to the liquid injection port of the corresponding battery cell; the number of vacuum suction nozzles can be set according to the specific scenario, for example, set to 5, 6, 7, etc., and this embodiment is not limited here.

[0131] In the embodiment of the present application, the position of the liquid injection port of each battery cell is located by a visual positioning device and stored in a target storage area, and the position of the liquid injection port of each battery cell is obtained from the target storage area, thereby improving the efficiency of obtaining the liquid injection port position.

Referring to FIG11 , the seal installation system includes a visual positioning device 300, an installation station 100, a controller 400, and a suction assembly 20. Both the visual positioning device 300 and the suction assembly 20 are in communication with the controller 400, and the visual positioning device 300 is positioned above the installation station 100. The installation station 100 is used to place multiple battery cells 10.

The controller 400 is configured to control each suction assembly 20 to absorb a seal 30, adjust the spacing between the suction assemblies 20 based on the position of the liquid injection port 101, and control the suction assembly 20, after adjusting the spacing, to install the absorbed seal 30 into the liquid injection port 101 of the corresponding battery cell 10 on the installation station 100.

The visual positioning device 300 and the suction component 20 both establish communication connections with the controller 400. The visual positioning device 300 is arranged above the installation station 100. The installation station 100 is used to place multiple battery cells 10. The visual positioning device 300 is used to locate the liquid injection ports 101 of the multiple battery cells 10 placed on the installation station 100, and send the located liquid injection port 101 position of each battery cell 10 to the controller 400. The controller 400 adjusts the component spacing between each suction component 20 according to the position of the liquid injection port 101, and controls each suction component 20 after adjusting the component spacing to install the sucked seal 30 to the liquid injection port 101 of the corresponding battery cell 10. Multiple seals 30 can be installed at one time, which shortens the installation time of the seal 30 and improves the production line efficiency.

Assuming that there are four suction components 20X1, X2, X3 and X4, the controller 400 controls X1 to move according to S1, controls X2 to move according to S2, controls X3 to move according to S3, and controls X4 to move according to S4, so that the moved suction components 20 correspond to the liquid injection ports 101 of D1, D2, D3, and D4 respectively. The controller 400 controls each suction component 20 to move to a preset installation position, and controls X1 to install the sucked seal 30 to the liquid injection port 101 of D1, controls X2 to install the sucked seal 30 to the liquid injection port 101 of D2, controls X3 to install the sucked seal 30 to the liquid injection port 101 of D3, and controls X4 to install the sucked seal 30 to the liquid injection port 101 of D4; the number of suction components 20 can be set according to the specific scenario, for example, set to 5, 6, 8, etc., and this embodiment is not limited here.
