For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0084] At present, in the process of installing seals, the feeding robot is generally controlled to pick up the seals multiple times, and the visual positioning device takes pictures to locate them. After the positioning is completed, the feeding robot is controlled to move and install the seals one by one to the injection port of the battery cell according to the injection port position obtained by positioning. In this process, the feeding robot needs to be controlled to pick up the seals multiple times, and only one seal can be installed to the injection port of the battery cell at a time. If the number of battery cells that need to install seals is large, it will take a long time, resulting in low production line efficiency. Therefore, how to improve the installation efficiency of seals has become a technical problem that needs to be solved urgently.

[0085] In order to solve the above technical problems, the embodiments of the present invention provide a seal installation control method, system, device, equipment and storage medium, which obtains the position of the injection port of each battery cell on the installation station, and adjusts the component spacing between each suction component for sucking the seal according to the position of the injection port of each battery cell, so that each suction component after the adjustment of the component spacing corresponds to the injection port of each battery cell. After the adjustment of the component spacing, each suction component is controlled to install the sucked seal to the injection port of the corresponding battery cell.

[0086] In a first aspect, an embodiment of the present invention provides a seal installation control method, referring to Figure 1 , Figure 1 It is a flow chart of an embodiment of a seal installation control method according to an embodiment of the present invention.

[0087] In this embodiment, the seal installation control method includes the following steps:

[0088] Step S1: Obtain the position of the liquid injection port of each battery cell on the installation station.

[0089] 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 a spatial position of the liquid injection port.

[0090] 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.

[0091] The suction component may be a component for sucking the sealing member. The component spacing may be the distance between each suction component. The sealing member may be a component for sealing the liquid injection port of the battery cell.

[0092] Step S3: After adjusting the spacing between components, each suction component is controlled to install the suctioned seal to the liquid injection port of the corresponding battery cell on the installation station.

[0093] In one example, the controller obtains the position of the injection port of each battery cell placed on the installation station through a positioning device. According to the position of the injection port, the suction components are controlled to move, thereby adjusting the component spacing between the suction components, so that each suction component after the component spacing is adjusted corresponds to the injection port of each battery cell. The suction components are controlled to install the sucked seals to the injection ports of the corresponding battery cells respectively.

[0094] In another example, refer to Figure 2 , Figure 2This is a schematic diagram for installing a seal. Suppose that four battery cells are placed on the installation station, which are represented as D1, D2, D3 and D4 respectively. The positioning device is used to position the injection ports of the four battery cells, and the positions of the injection ports of the four battery cells are S1, S2, S3 and S4 respectively. Suppose that there are four suction components X1, 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 correspond to the injection ports of D1, D2, D3, and D4 respectively. The controller controls each suction component to move to a preset installation position, and controls X1 to install the sucked seal to the liquid injection port of D1, controls X2 to install the sucked seal to the liquid injection port of D2, controls X3 to install the sucked seal to the liquid injection port of D3, and controls X4 to install the sucked seal to the liquid injection port of D4; the number of suction components can be set according to the specific scenario, for example, set to 5, 6, 8, etc., and this embodiment is not limited here.

[0095] This embodiment adjusts the component spacing between each suction component according to the position of the injection port of each battery cell on the installation station, so that each suction component used for sucking the seal corresponds to the injection port of each battery cell, and each suction component after adjusting the component spacing is controlled to install the sucked seal to the 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 injection port of each battery cell, and controlling each suction component to install the sucked seal to the injection port of the corresponding battery cell, multiple seals can be installed at one time, which shortens the time for installing the seal and improves the production line efficiency.

[0096] In some embodiments, reference Figure 3 , the step S3 comprises:

[0097] Step S31: Control each suction component after adjusting the component spacing to move to a preset installation position.

[0098] The preset installation position may be a preset position for installing the sealing member toward the liquid injection port.

[0099] 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 injection port, so that each suction component corresponds to the 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 injection port of the battery cell.

[0100] Step S32: when each suction component moves to the preset installation position, each suction component is controlled to install the sealing member sucked by each suction component to the liquid injection port of the corresponding battery cell on the installation station.

[0101] 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 a 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 locate the injection port of each battery cell on the installation station to obtain the position of the injection port of each battery cell, and the component spacing between each suction component on the manipulator is adjusted according to the position of the injection port of each battery cell, so that the adjusted component spacing corresponds to the spacing between the injection ports of each battery cell, the manipulator is controlled to move to a 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.

[0102] In another example, refer to Figure 4 , Figure 4 To provide a schematic diagram for adjusting the spacing between components, assume that three battery cells are placed on the installation station, represented by D11, D12 and D13, and there are four suction components X1, X2, X3 and X4. The injection ports of the three battery cells are positioned by a visual positioning device, and the coordinates of the injection ports are obtained as follows: (a1, b1, c1), (a2, b2, c2) and (a3, b3, c3), respectively. Then, the spacing adjustment component is controlled to drive X1 to move to a preset position, drive X2 to move so that the distance between X2 and X1 is adjusted to (b2-b1), and drive X3 to move so that the distance between X3 and X2 is adjusted to (b3-b2). After the spacing is adjusted, X1, X2 and X3 correspond to D11, D12 and D13, respectively. X1 is controlled to install the sucked seal to the injection port of D11, X2 is controlled to install the sucked seal to the injection port of D12, and X3 is controlled to install the sucked seal to the injection port of D13.

[0103] In the embodiment of the present application, each suction component is controlled to move to a preset installation position after adjusting the component spacing, and when each suction component is moved to the preset installation position after adjusting the component spacing, each suction component is controlled to install the respectively sucked sealant to the 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 injection port of the corresponding battery cell, the time for installing the sealant is saved and the production line efficiency is improved.

[0104] In some embodiments, reference Figure 5 , the step S3 further comprises:

[0105] Step S311: Control each suction component after adjusting the spacing to move to a preset loading position, and control each suction component at the preset loading position to suck the seal.

[0106] The preset loading position may be a preset position where the suction assembly sucks the seal.

[0107] As an implementation method, each suction component is arranged on a manipulator, and the manipulator is controlled to move to a preset loading position, thereby driving each suction component to move to the preset loading position.

[0108] Step S312: When each suction component sucks the seal, control each suction component to move to a preset installation position.

[0109] Step S313: controlling each suction assembly at a preset installation position to install the suctioned seal to the liquid injection port of the corresponding battery cell at the installation station.

[0110] 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 liquid injection port of each battery cell on the installation station is positioned by a positioning device 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 each suction component after the component spacing is adjusted corresponds to the liquid injection port of the battery cell, the manipulator is controlled to drive the suction components after the component spacing is adjusted to move to a preset loading position, and each suction component at the preset loading position is controlled 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 sealing component to move to a preset installation position, and each suction component at the preset installation position corresponds to the liquid injection port of each battery cell, and each suction component is controlled to install the sucked seal to the liquid injection port of the corresponding battery cell.

[0111] 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.

[0112] In some embodiments, adjusting the component spacing between the suction components according to the position of the injection port includes:

[0113] 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.

[0114] The spacing adjustment component may be a component used to adjust the distance between the suction components by driving the suction components to move.

[0115] In one example, for example, the number of spacing adjustment components is equal to the number of suction components, the spacing adjustment components and the suction components are arranged correspondingly, and 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 the suction components, so that the distance between the suction components after the component distance is adjusted corresponds to the distance between the liquid injection ports of each battery cell.

[0116] 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 component spacing is automatically adjusted by the spacing adjustment component, which improves the accuracy of spacing adjustment and the efficiency of component spacing adjustment.

[0117] In some embodiments, the spacing adjustment component is a spacing servo motor, and the servo motor is arranged corresponding to each suction component, and each servo motor is used to adjust the position of the corresponding suction component.

[0118] 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.

[0119] 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 each adjusted 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.

[0120] In an example, assuming that the seal is an aluminum nail, the suction component is a suction nozzle, the suction nozzle is arranged on a three-axis manipulator, 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 injection port of each battery cell on the installation station, obtains the injection port position of each battery cell, controls the spacing servo motor to operate according to the injection port position of each battery cell, so as to adjust the nozzle spacing between each suction nozzle, and each suction nozzle after adjusting the nozzle spacing corresponds to the injection port of each battery cell, controls the manipulator to move to a preset loading position, and controls the Z axis of the manipulator 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 manipulator is controlled to rise to the preset loading position, and the manipulator is controlled to move to the preset installation position, and the Z axis of the manipulator at the preset installation position is controlled to descend to the preset nail placement position, and the negative pressure corresponding to each suction nozzle is controlled to be closed, so that the aluminum nail absorbed by each suction nozzle is installed to the injection port of the corresponding battery cell.

[0121] In another example, referring to FIG6 , FIG6 is a schematic diagram of adjusting the nozzle spacing by a spacing servo motor, FIG6(a) is a schematic diagram before the nozzle spacing is adjusted by the spacing servo motor, and FIG6(b) is a schematic diagram after the nozzle spacing is adjusted by the spacing servo motor. Four spacing servo motors J1, J2, J3 and J4 are arranged on the manipulator, corresponding to the nozzles Z1, Z2, Z3 and Z4 respectively. Assuming that four battery cells are placed on the installation station, namely D21, D22, D23 and D24, the coordinates of the injection port of each battery cell 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, y 1,z1) controls J1 to adjust the coordinate of Z1 to (x,y1,z), controls J2 to adjust the coordinate of Z2 to (x,y2,z) according to (x2,y2,z2), controls J3 to adjust the coordinate of Z3 to (x,y3,z) according to (x3,y3,z3), controls J4 to adjust the coordinate of Z4 to (x,y4,z) according to (x4,y4,z4), the adjusted Z1 corresponds to the liquid injection port of D21, the adjusted Z2 corresponds to the liquid injection port of D22, the adjusted Z3 corresponds to the liquid injection port of D23, the adjusted Z4 corresponds to the liquid injection port of D24, controls Z1, Z2, Z3 and Z4 to install the sucked seals to D21, D22, D23 and D24 respectively.

[0122] In the embodiment of the present application, the spacing adjustment component is a servo motor, and the servo motor is set corresponding to each suction component. The position of the corresponding suction component is adjusted by each servo motor, thereby improving the accuracy of the position adjustment of the suction component.

[0123] In some embodiments, reference Figure 7 , step S32, comprising:

[0124] 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.

[0125] The suction assembly sucks the seal by negative pressure.

[0126] In one example, for example, the suction component is a suction nozzle, which is arranged 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 suction nozzle spacing between the suction nozzles, and controlling the manipulator to drive the suction nozzles with adjusted nozzle spacing to move to a preset installation position. When the manipulator drives the suction nozzles to move 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 battery cell corresponding to the installation station.

[0127] 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 seal sucked by each suction component is installed to the liquid injection port of the corresponding battery cell at the installation station, thereby achieving the effect of installing multiple seals at one time and improving the installation efficiency of the seals.

[0128] In some embodiments, reference Figure 8 , step S313, comprising:

[0129] 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 at the installation station.

[0130] In one example, the robot is controlled to drive the suction nozzle to move 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 move 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 sealing component sucked by it to the liquid filling port of the corresponding battery cell on the installation station.

[0131] 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 sucked by it to 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.

[0132] In some embodiments, reference Fig. 9 , step S1 comprises:

[0133] 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.

[0134] The visual positioning device can be a device that converts the detected object into an image signal and locates the object 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.

[0135] 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.

[0136] 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 a visual positioning device, thereby improving the positioning accuracy of the battery cell liquid injection port.

[0137] In some embodiments, reference Fig.10 , step S1 further includes:

[0138] Step S111: positioning the liquid injection port of each battery cell on the installation station by using 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.

[0139] The target storage area may be a preset storage area for storing the position of the liquid injection port.

[0140] Step S112: obtaining the position of the liquid injection port of each battery cell stored in the target storage area.

[0141] In an example, for example, 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, and the PLC reads the coordinates of the liquid injection port of each battery cell from the storage area corresponding to the label address.

[0142] In another example, refer to Fig.11For example, the sealing part is an aluminum nail, the visual positioning device is a CCD visual positioning device, the suction component is a vacuum nozzle, the spacing adjustment component is a spacing servo motor, the vacuum nozzle is arranged on a three-axis manipulator, the three-axis manipulator includes an X-axis, a Y-axis and a Z-axis, and each vacuum nozzle is correspondingly provided with a spacing servo motor, the vibration plate is controlled to send the aluminum nail component to the upper nail position (i.e., the preset loading position) through vibration displacement, after the manipulator is controlled to reach the preset loading position, the Z axis of the manipulator is controlled to descend to the preset suction position, the negative pressure corresponding to each vacuum nozzle is controlled to open to absorb the aluminum nail, and after the nail absorption is completed, the Z axis of the manipulator 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, the injection port coordinates of each injection port are obtained, and the EIP protocol is used. Receive the liquid injection port coordinates sent by the CCD visual positioning device, and store the received coordinates of each liquid injection port in a preset storage area corresponding to the label address, control the manipulator to move to the preset installation position, and control the spacing servo motor 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 nozzle after the adjustment of the spacing corresponds to the liquid injection port of the battery cell. If the manipulator reaches the preset installation position and the spacing adjustment between the suction nozzles is completed, control the Z axis of the manipulator to descend to the aluminum nail placement position. If the Z axis of the manipulator descends to the aluminum nail placement position, control the negative pressure corresponding to each vacuum suction nozzle 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.

[0143] 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.

[0144] In the second aspect, an embodiment of the present invention proposes a seal installation system, which includes a visual positioning device, an installation station, a controller and a suction component.

[0145] The seal installation system of this embodiment includes a visual positioning device, an installation station, a controller and a suction component. The visual positioning device and the suction component both establish a communication connection with the controller. The visual positioning device is arranged above the installation station. The installation station is used to place multiple battery cells.

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.

[0150] In some embodiments, the seal installation control system further includes a spacing adjustment component, which is connected to the suction component. The controller is also used to control the operation of the spacing adjustment component according to the position of the injection port.
