During the installation of the seal, the robot is controlled to suck the seal from the material station and then install the sucked seal to the liquid injection port of the battery cell. If a large number of battery cells need to be installed with seals, the robot needs to be controlled to frequently pick up and place the seals back and forth, which takes a long time and leads to low production line efficiency.

[0007] In a first aspect, an embodiment of the present application provides a seal installation control method, the method comprising the following steps:

[0008] Obtain the sealing position of each sealing member on the material station; control each suction component to suck the corresponding sealing member on the material station according to the sealing position; and control each suction component to install the sucked sealing member to the liquid injection port of the battery cell.

In the process of installing the seal, multiple seals can be sucked for installation without frequently taking and placing the seals back and forth, which shortens the installation time of the seal and improves the installation efficiency of the seal.

[0010] In some embodiments, controlling each suction component to suck the corresponding seal on the material station according to the seal position includes: controlling each suction component to suck the seal at the corresponding position on the material station in sequence according to the target seal position until each suction component sucks the seal, and the target seal position is feedback from the loading visual positioning device based on the received trigger signal.

[0011] This embodiment controls each suction component to suck the seal at the corresponding position on the material station in sequence according to the target seal position fed back by the loading visual positioning device, until each suction component sucks the seal. It can suck multiple seals and then install the seals without the need to frequently pick up and place the seals back and forth, and can complete the suction of the seals to be installed before the battery cells of the previous process arrive, thereby shortening the installation time of the seals and improving the installation efficiency of the seals.

[0015] In this embodiment, each seal on the material workstation is positioned by a loading visual positioning device, and a trigger signal is sent to the loading visual positioning device according to the current suction state of the suction component, and the target seal position fed back by the loading visual positioning device based on the trigger signal is obtained. The loading visual positioning device can be controlled to feed back the target seal position according to the suction state of the suction component, thereby improving the seal positioning accuracy and the seal suction efficiency.

[0016] In some embodiments, obtaining the seal position of each seal on the material station includes: positioning each seal on the material station through a loading visual positioning device, and obtaining the seal position of each seal obtained by the loading visual positioning device.

[0019] In this embodiment, the component spacing between each suction component is adjusted according to the position of the liquid injection port of each battery cell on the installation station, so that each suction component corresponds to the liquid injection port of each battery cell. After the component spacing is adjusted, each suction component is controlled to install the sucked seal to the liquid injection port of the corresponding battery cell on the installation station. Multiple seals can be installed at one time, which shortens the installation time of the seal and improves the production line efficiency.

[0020] In some embodiments, the component spacing between each suction component is adjusted according to the position of the liquid injection port of each battery cell on the installation station so that each suction component corresponds to the liquid injection port of each battery cell, including: positioning the liquid injection port of each battery cell on the installation station by a discharge visual positioning device to obtain the position of the liquid injection port of each battery cell; adjusting the component spacing between each suction component according to the position of the liquid injection port so that each suction component corresponds to the liquid injection port of each battery cell.

[0021] In this embodiment, the liquid injection port of each battery cell on the installation station is positioned by a discharge visual positioning device to obtain the position of the liquid injection port of each battery cell, and the component spacing between each suction component 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 each battery cell on the installation station, and each suction component can be adjusted to correspond to the liquid injection port of each battery cell according to the position of the liquid injection port of each battery cell, thereby realizing the installation of multiple seals at one time and improving the installation efficiency of the seals.

During the process of installing the seal, multiple seals can be absorbed, eliminating the need for frequent back and forth pick-up and placement of the seals, thereby shortening the installation time of the seals and improving the installation efficiency of the seals.

[0071] At present, in the process of installing seals, the robot is generally controlled to suck the seals, and then the robot is controlled to install the seals to the liquid injection port of the battery cell according to the position of the liquid injection port of the battery cell. After the installation is completed, the robot is controlled to continue to suck the seals. During this process, it is necessary to frequently control the robot to suck the seals back and forth multiple times. If a large number of battery cells need to be installed with seals, the installation will take a lot of time, resulting in low production line efficiency. Therefore, how to improve the installation efficiency of seals has become a technical problem that urgently needs to be solved.

[0072] To address the aforementioned technical issues, embodiments of the present application provide a seal installation control method, system, device, apparatus, and storage medium. The method obtains the seal position of each seal at a material station. Based on the seal position of each seal, each suction assembly is controlled to extract the corresponding seal at the material station. Each suction assembly is then controlled to install the extracted seal into the liquid injection port of a battery cell.

[0073] 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.

[0074] In this embodiment, the seal installation control method includes the following steps:

[0075] Step S1: Obtain the sealing element position of each sealing element on the material station.

[0076] The material station can be a station where a seal is placed. The seal can be a component used to seal the liquid injection port of a battery cell. The seal position can be the spatial location of the seal, including but not limited to seal coordinates, seal positioning, etc.

[0077] Step S2: controlling each suction component to suck the corresponding seal on the material station according to the position of the seal.

[0078] The suction assembly may be an assembly for sucking the seal.

[0079] Step S3: controlling each suction assembly to install the sucked seal to the liquid injection port of the battery cell.

[0080] As an implementation method, the sealing positions of each seal placed on the material station are obtained, and multiple sealing positions equal to the number of suction components are selected from the sealing positions corresponding to each seal. According to the selected multiple sealing positions, each corresponding suction component is controlled to absorb the seal on the material station, and each suction component is controlled to install the absorbed seal to the liquid filling port of each battery cell.

[0081] In one example, referring to FIG2 , FIG2 is a schematic diagram of the suction seal, assuming that there are three suction components X1, X2 and X3, and the three seal positions selected from the seal positions corresponding to the seals on the material station are S1, S2 and S3 respectively. Assuming that X1 corresponds to S1, X2 corresponds to S2, and X3 corresponds to S3, the suction component is controlled according to S1 to suck the seal at S1 on the material station, the suction component is controlled according to S2 to suck the seal at S2 on the material station, and the suction component is controlled according to S3 to suck the seal at S3 on the material station. After each suction component sucks the seal, X1, X2 and X3 are controlled to install the sucked components to the liquid injection port of the corresponding battery cell, respectively. The number of suction components can also be other values, such as 4, 5, 6, etc., which is not limited in this embodiment.

[0082] In the embodiment of the present application, the sealing position of each seal on the material station is obtained, and each suction component is controlled to suck the corresponding seal on the material station according to the sealing position of each seal, and each suction component is controlled to install the sucked seal to the liquid injection port of the battery cell. In the process of installing the seal, multiple seals can be sucked, and there is no need to frequently take and place the seals back and forth, which shortens the installation time of the seal and improves the installation efficiency of the seal.

[0083] In some embodiments, referring to FIG3 , step S2 includes:

[0084] Step S21: Control each suction component to suck the seal at the corresponding position on the material station in sequence according to the target seal position, until each suction component sucks the seal. The target seal position is feedback from the loading visual positioning device based on the received trigger signal.

[0085] The target seal position may be the position of the seal currently being controlled to be picked up by the suction assembly. The loading visual positioning device may be a device for positioning the seal on the material station, including but not limited to a CCD camera (charge coupled device camera) and a 3D visual positioning device. The trigger signal may be a signal that triggers the loading visual positioning device to provide feedback on the seal position.

[0086] As an implementation method, the controller sends a trigger signal to the loading visual positioning device. When the loading visual positioning device receives the trigger signal, it feeds back the target seal position to the controller. The controller controls the corresponding suction component to suck the seal at the corresponding position on the material station according to the target seal position. If the suction component sucks the seal, it continues to send a trigger signal to the loading visual positioning device, and controls the next suction component to suck the seal according to the target seal position fed back by the loading visual positioning device, until all suction components suck the seal.

[0087] In an example, assuming there are four suction components, the controller sends a trigger signal to the loading visual positioning device, the loading visual positioning device sends the first seal position to the controller, and the controller controls the first suction component to suck the seal at the corresponding position on the material station according to the first seal position. After the first suction component sucks the seal, it continues to send a trigger signal to the loading visual positioning device, the loading visual positioning device sends the second seal position to the controller, and the controller controls the second suction component to suck the seal at the corresponding position on the material station according to the second seal position. After the second suction component sucks the seal, it continues to send a trigger signal to the loading visual positioning device until all four suction components suck the seal. This embodiment does not limit the number of suction components and seal positions.

[0088] In another example, assuming there are three suction components, namely X1, X2 and X3, the controller sends a trigger signal to the feeding visual positioning device, the feeding visual positioning device sends the seal coordinates (a1, b1, c1) to the controller, the controller controls X1 to move to (a1, b1, c) according to the coordinates (a1, b1, c1), and controls X1 to descend and suck the seal with coordinates (a1, b1, c1) on the material station; after X1 sucks the seal, it continues to send a trigger signal to the feeding visual positioning device, the feeding visual positioning device sends the seal coordinates (a2, b2, c2) to the controller, and the controller controls X1 to move to (a1, b1, c) according to the coordinates (a2, b2 ,c2) controls X2 to move to (a2,b2,c), and controls X2 to descend and absorb the seal with coordinates (a2,b2,c2) on the material station; after X2 absorbs the seal, it continues to send a trigger signal to the loading visual positioning device, and the loading visual positioning device sends the seal coordinates (a3,b3,c3) to the controller. The controller controls X3 to move to (a3,b3,c) according to (a3,b3,c3), and controls X3 to descend and absorb the seal with coordinates (a3,b3,c3) on the material station, until all three absorption components absorb the seal, and control the three absorption components to install the absorbed seals to the liquid filling ports of the corresponding battery cells.

[0089] In the embodiment of the present application, each suction component is controlled in sequence to suck the seal at the corresponding position on the material station according to the target seal position fed back by the loading visual positioning device, until each suction component sucks the seal. It can suck multiple seals and then install the seals without the need to frequently pick up and place the seals back and forth, and the suction of the seals to be installed can be completed before the battery cells of the previous process arrive, which shortens the installation time of the seals and improves the installation efficiency of the seals.

[0090] In some embodiments, referring to FIG. 4 , step S2 further includes:

[0091] Step S211: Read the sealing element positions from the preset storage area in sequence.

[0092] The preset storage area may be a pre-set storage area for storing the seal positions. The sequential reading may be reading the seal positions one by one according to the storage order of the seal positions in the preset storage area, and the storage order includes but is not limited to the storage time order, the storage number order, etc.

[0093] Step S212: controlling the corresponding suction component to suck the corresponding seal on the material station according to the read seal position, until each suction component sucks the seal.

[0094] As an implementation method, when the seal position is received from the loading and positioning device, the seal position is stored in a preset storage area, and the seal position is read one by one from the preset storage area. According to the currently read seal position, the suction component is controlled to suck the seal at the corresponding position on the material station until each suction component sucks the seal.

[0095] In an example, assuming that there are multiple seals on the material station, the loading and positioning device positions each seal on the material station, obtains several seal positions, and sends the several seal positions to the controller. The several seal positions are stored in a preset storage area. The controller reads the seal positions one by one according to the storage order, and controls the suction component to suck the seal at the corresponding position on the material station according to the currently read seal position until each suction component sucks up the seal.

[0096] In another example, assuming that there are multiple seals on the material station, the number of suction components is N, where N is a positive integer, the loading and positioning device positions the multiple seals on the material station to obtain several seal positions, and determines the suction distance based on the seal position and the position of the suction component. According to the suction distance, the N seal positions that are close to the suction component are sent to the controller, and the N seal positions are stored in a preset storage area. The controller reads the seal positions one by one according to the storage order, and controls the suction component to absorb the seal according to the read seal positions until all N suction components absorb the seals.

[0097] In the embodiment of the present application, the seal positions are read sequentially from the preset storage area, and the corresponding suction components are controlled according to the read seal positions to suck the corresponding seals on the material station until each suction component sucks up the seals. There is no need to frequently take and place the seals back and forth, and the suction of the seals to be installed can be completed before the battery cells of the previous process arrive, which shortens the installation time of the seals and improves the installation efficiency of the seals.

[0098] In some embodiments, referring to FIG. 5 , step S1 includes:

[0099] Step S11: Position each seal on the material station through the loading visual positioning device, and send a trigger signal to the loading visual positioning device according to the current suction state of the suction component.

[0100] The current suction state may be a state of whether the suction component has sucked the sealing member. If the current suction state of the suction component is that the sealing member has been sucked, a trigger signal is sent to the feeding visual positioning device.

[0101] Step S12: obtaining the target seal position fed back by the feeding visual positioning device based on the trigger signal.

[0102] As an implementation method, each seal on the material station is positioned by a loading visual positioning device, and the controller determines the current suction state of the current suction component. If the current suction state is that the seal is sucked, a trigger signal is sent to the loading visual positioning device so that the loading visual positioning can feedback the target seal position according to the trigger signal. After the controller obtains the target seal position, it controls the next suction component to suck the seal at the corresponding position on the material station according to the target seal position until each suction component sucks the seal.

[0103] In the embodiment of the present application, each seal on the material station is positioned by a loading visual positioning device, and a trigger signal is sent to the loading visual positioning device according to the current suction state of the suction component, and the target seal position fed back by the loading visual positioning device based on the trigger signal is obtained. The loading visual positioning device can be controlled to feed back the target seal position according to the suction state of the suction component, thereby improving the seal positioning accuracy and the seal suction efficiency.

[0104] In some embodiments, referring to FIG. 6 , step S1 further includes:

[0105] Step S111: positioning each seal on the material station by a material loading visual positioning device, and obtaining the sealing position of each seal positioned by the material loading visual positioning device.

[0106] As an implementation method, the controller controls the loading visual positioning device to position each seal on the material station and obtain the seal position of each seal. The controller obtains the seal position of each seal sent by the loading positioning device.

[0107] In an example, it is assumed that the sealing part is a glue nail, the suction component is a vacuum suction nozzle, the controller is a programmable logic controller (PLC), the material station includes a glue nail placement tray and a flexible vibration tray, the suction component is a vacuum suction nozzle, and the suction component is arranged on a robot. The glue nails are placed on the glue nail placement tray, and the glue nail placement tray transports the glue nails to the flexible vibration tray through vibration. The loading CCD visual positioning device positions the glue nails on the flexible vibration tray and sends the glue nail coordinates of each glue nail obtained by positioning to the PLC. The PLC controls the robot to reach the preset material picking position. The PLC controls the robot to move to the corresponding position of the flexible vibration tray according to the glue nail coordinates, controls the lifting cylinder of the corresponding vacuum suction nozzle to descend, and controls the vacuum suction nozzle to open negative pressure to absorb the glue nail. After the glue nail is absorbed, the lifting cylinder rises, and controls the robot to move to the next corresponding position according to the next glue nail coordinate. The glue nails are absorbed in a cycle until all vacuum suction nozzles have absorbed the glue nails.

[0108] In another example, due to the small size of the glue nails, it is necessary to control the suction component to suck the glue nails one by one, control the glue nail plate to transport the glue nails to the flexible vibration plate through vibration, control the suction component to suck the glue nails on the flexible vibration plate one by one, and the PLC controls the loading CCD visual positioning device to position the glue nails on the flexible vibration plate. The loading CCD visual positioning device sends the coordinates of the glue nails close to the suction component to the PLC according to the proximity principle. The PLC controls the corresponding vacuum suction nozzle to suck the glue nails at the corresponding position on the flexible vibration plate according to the received glue nail coordinates. After the vacuum suction nozzle sucks the glue nails, the PLC sends a signal to the loading CCD visual positioning device. After receiving the signal, the loading CCD visual positioning device continues to send the glue nail coordinates to the PLC according to the proximity principle. The PLC controls the corresponding vacuum suction nozzle to suck the glue nails at the corresponding position on the flexible vibration plate according to the glue nail coordinates until each vacuum suction nozzle sucks the glue nails.

[0109] In the embodiment of the present application, each seal on the material station is positioned by a feeding visual positioning device, and the sealing position of each seal obtained by the feeding visual positioning device is obtained, thereby improving the positioning accuracy of the seal.

[0110] In some embodiments, referring to FIG. 7 , step S3 includes:

[0111] Step S31: adjusting the component spacing between the suction components according to the position of the liquid injection port of each battery cell on the installation station, so that each suction component corresponds to the liquid injection port of each battery cell.

[0112] The component spacing may be the distance between each suction component. The component spacing may be the distance between each suction component. 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.

[0113] Step S32: controlling each suction assembly after adjusting the assembly spacing to install the sucked seals to the liquid injection ports of the corresponding battery cells on the installation station.

[0114] In one example, a controller uses a visual positioning device to locate the injection port of each battery cell placed at the installation station. Based on the injection port location, the controller controls the movement of each suction assembly, adjusting the spacing between the suction assemblies so that each assembly aligns with the injection port of each battery cell. The controller then controls each suction assembly to install the suctioned sealant into the corresponding battery cell's injection port.

[0115] In another example, referring to Figure 8, Figure 8 is a schematic diagram of installing a seal. If there are four battery cells placed on the installation station, which are represented as D1, D2, D3 and D4 respectively, the injection ports of the four battery cells are positioned by the discharge visual positioning device, and the positions of the injection ports of the four battery cells are obtained as k1, k2, k3 and k4 respectively. Assuming that there are four suction components X1, X2, X3 and X4, the controller controls X1 to move according to k1, controls X2 to move according to k2, controls X3 to move according to k3, and controls X4 to move according to k4, 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 does not limit this.

[0116] In the embodiment of the present application, the component spacing between each suction component is adjusted according to the position of the liquid injection port of each battery cell on the installation station, so that each suction component corresponds to the liquid injection port of each battery cell. After the component spacing is adjusted, each suction component is controlled to install the sucked seal to the liquid injection port of the corresponding battery cell on the installation station. Multiple seals can be installed at one time, which shortens the installation time of the seal and improves the production line efficiency.

[0120] Step S312: adjusting the component spacing between the suction components according to the position of the liquid injection port, so that each suction component corresponds to the liquid injection port of each battery cell.

[0121] In one example, a discharge visual positioning device is arranged above the installation station, and a controller controls the discharge 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 adjusts the component spacing between each suction component according to the position of the liquid injection port of each battery cell, so that the adjusted each suction component corresponds to the liquid injection port of each battery cell.

[0122] In the embodiment of the present application, the liquid injection port of each battery cell on the installation station is positioned by a discharge visual positioning device to obtain the position of the liquid injection port of each battery cell, and the component spacing between each suction component 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 each battery cell on the installation station, and each suction component can be adjusted to correspond to the liquid injection port of each battery cell according to the position of the liquid injection port of each battery cell, thereby realizing the installation of multiple seals at one time and improving the installation efficiency of the seals.

[0123] In some embodiments, adjusting the component spacing between the suction components according to the position of the liquid injection port includes:

[0124] 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.

[0125] The spacing adjustment component may be a component used to adjust the distance between the suction components by driving the suction components to move.

[0126] As an implementation method, the spacing adjustment component is a spacing servo motor, and the spacing servo motor is correspondingly provided to each suction component, and each servo motor is used to adjust the position of the corresponding suction component.

[0127] In one example, for example: 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 the discharge visual positioning device, and the spacing servo motor is controlled to operate 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 each suction component is controlled to install the sucked seal to the liquid injection port of the corresponding battery cell.

[0128] 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.

[0129] In some embodiments, referring to FIG. 10 , step S32 includes:

[0130] Step S321: upon receiving a discharge permission signal from the installation station, controlling each suction assembly after adjusting the spacing to install the sucked seal to the liquid injection port of the corresponding battery cell on the installation station.

[0131] The discharge permission signal may be a signal that allows the suction component to install the seal to the liquid filling port of the battery cell.

[0132] In an example, assuming that the seal is a glue nail, when each suction component has sucked up the glue nail, the PLC controls the discharge CCD visual positioning device to locate the liquid injection port of the battery cell on the installation station to obtain the position of the liquid injection port of each battery cell. The PLC controls the corresponding spacing servo motor to drive the vacuum suction nozzle to move according to the position of the liquid injection port of each battery cell, so that the spacing between each vacuum suction nozzle is consistent with the spacing between the liquid injection ports of the corresponding battery cells. The PLC controls the manipulator to drive the vacuum suction nozzle with adjusted spacing to the preset installation position. When the PLC receives the discharge permission signal sent by the installation station, it controls the lifting cylinder to descend to the preset position and controls the negative pressure of each vacuum suction nozzle to close, thereby installing the glue nail sucked by each vacuum suction nozzle to the liquid injection port of the corresponding battery cell to complete the installation of the glue nail. The manipulator can be a two-axis manipulator, a three-axis manipulator, etc., which is not limited in this embodiment.

[0133] In another example, referring to FIG11 , FIG11 is a schematic diagram of adjusting the nozzle spacing by a spacing servo motor, FIG11(a) is a schematic diagram before the spacing servo motor is controlled to adjust the nozzle spacing, and FIG11(b) is a schematic diagram after the spacing servo motor is controlled to adjust the nozzle spacing. Four spacing servo motors J1, J2, J3 and J4 are set on the manipulator, corresponding to the vacuum nozzles Z1, Z2, Z3 and Z4 respectively. Assuming that there are four battery cells placed on the installation station, namely D21, D22, D23 and D24, the coordinates of the liquid 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), and the PLC calculates the liquid injection port according to (x1, y1, z1), (x2, y2, z2), (x3, y3, z3) and (x4, y4, z4). 1,y1,z1) controls J1 to adjust the coordinate of Z1 to (x,y1,z), according to (x2,y2,z2) controls J2 to adjust the coordinate of Z2 to (x,y2,z), according to (x3,y3,z3) controls J3 to adjust the coordinate of Z3 to (x,y3,z), according to (x4,y4,z4) controls J4 to adjust the coordinate of Z4 to (x,y4,z), 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, and the adjusted Z4 corresponds to the liquid injection port of D24. Control Z1, Z2, Z3 and Z4 to install the sucked glue nails to D21, D22, D23 and D24 respectively.
