The installation device sends the acquired second coordinates to the grasping device, so that the grasping device does not need to acquire the coordinates of the installation position of the lower shell when it needs them, which saves time and improves the production efficiency of the battery.

[0021] In some embodiments, the installation device further includes at least one tightening gun, which is connected to the controller. The controller controls the tightening gun to tighten the screws inserted into the first mounting hole and the second mounting hole according to the second coordinate to fix the battery module to the mounting position of the lower shell.

[0048] The core of Industry 4.0 is data, and the digital construction of enterprises cannot be achieved overnight. The battery production process begins to face the problem of difficulty in integrating multiple isolated data sources. Integrating isolated data sources, being able to conduct horizontal and vertical comprehensive analysis of business data, and data storage and traceability are becoming increasingly important in the battery pack production process.

[0049] With the development of new energy vehicles, the demand for battery production is increasing, so the manufacturing requirements and process equipment for battery production need to be improved. At present, the degree of automation in the installation and molding of batteries is low.

[0050] The inventors have noticed that in the existing battery production process, automated equipment is used only when the battery module is fixed to the lower shell, while the process of placing the battery module on the lower shell cannot meet the automation requirements. The battery module is placed in the box by manual operation, and the robot arm assists in grabbing the battery module and placing it in the lower box. The whole process is inefficient and wastes manpower. Improper grabbing may also cause the battery module to fall and hit people.

[0051] In order to improve the degree of automation in the production and installation of batteries, the applicant has found that the grabbing process of the battery module can also be automated.

[0052] Based on the above considerations, in order to solve the problem of low automation in the battery production process, the inventor has designed a battery forming system after in-depth research. By setting a grasping device and an installation device, the grasping device grasps the battery module to the corresponding installation position on the lower shell, and then the battery module is installed and fixed to the lower shell through the installation device, thereby realizing the fully automatic installation of the battery module on the lower shell.

[0053] Through such a battery forming system, the grabbing process of the battery module is completed by the grabbing device, and the installation and fixing process of the battery module is completed by the installation device, so that no manual operation is required during the grabbing and installation process of the battery module, which saves human resource costs, improves battery production efficiency, reduces production costs, and greatly improves safety.

[0054] Through such a battery forming system, the installation device will send the collected second coordinates of the second installation hole at the installation position in the base coordinate system to the grasping device, so that the grasping device does not need to collect the coordinates of the second installation hole at the installation position, thereby saving time and improving the efficiency of battery production.

[0055] The battery molding system disclosed in the embodiment of the present application can be used in battery production. The battery molding system disclosed in the present application can be used to grab and install the battery module. During the grabbing and installing process of the battery module, the battery molding system is set up to make the whole process fully automated, improve production efficiency, reduce labor, and improve safety.

[0056] For the convenience of description, the following embodiments are described by taking a battery forming method according to an embodiment of the present application as an example.

The entire process of the battery module 16 from grasping to installation and fixing is fully automatically completed, which improves production efficiency and reduces costs.

[0061] The reference coordinate system is a coordinate system created at a certain position around the grasping device and the installation device. Its purpose is to make the movement of the robot and the programmed position all refer to this coordinate system. The grasping device 11 and the installation device 12 respectively collect the first coordinate and the second coordinate of the first installation hole of the battery module 16 and the second installation hole of the installation position 172 of the lower shell 17 in the base coordinate system. The first coordinate and the second coordinate are offset values ​​in the base coordinate system. The coordinates of the first coordinate in the base coordinate system are (X1, Y1, A1), and the coordinates of the second coordinate in the base coordinate system are (X2, Y2, A2), wherein X1 and X2 are offset values ​​of the X axis in the base coordinate system, Y1 and Y2 are offset values ​​of the Y axis in the base coordinate system, and A1 and A2 are angle offset values ​​in the base coordinate system. By acquiring the first coordinate and the second coordinate, the accurate position of the battery module 16 and the installation position 172 can be obtained, which improves the accuracy of the position, thereby improving the qualified rate in the subsequent grasping, placing and fixing process.

[0062] In the battery forming system 1, a gripping device 11 and an installation device 12 are included. The gripping device 11 and the installation device 12 respectively collect the coordinates of the first installation hole of the battery module 16 and the second installation hole of the installation position 172 of the lower shell 17 in the base coordinate system. The coordinates collected by the gripping device 11 and the installation device 12 are both in the base coordinate system, so that the coordinates collected by the two can be shared. The second coordinate of the second installation hole of the installation position 172 of the lower shell 17 collected by the installation device 12 can be shared with the gripping device 11, thereby reducing the work task of the gripping device 11, improving the operation efficiency of the gripping device 11, and improving the assembly cycle. The gripping device 11 grabs the battery module 16 from the first coordinate to the second coordinate according to the first coordinate and the second coordinate, thereby completing the boxing of the battery module 16, so that the battery module 16 is grabbed from the initial position to the installation position 172 of the lower shell 17, and then the installation device 12 installs the battery module 16 to the installation position 172 through the second coordinate, thereby completing the boxing and installation of the battery module 16. Thus, through the cooperation between the grasping device 11 and the installation device 12, the battery module 16 is placed on the installation position 172 of the lower shell 17 and fixedly installed, thereby realizing a fully automatic grasping and installation process and improving production efficiency.

[0063] According to some embodiments of the present application, optionally, the battery forming system 1 further includes a controller, which is signal-connected to the gripping device 11 and the mounting device 12 , respectively, receives the second coordinate sent by the mounting device 12 , and sends the second coordinate to the gripping device 11 .

[0065] The controller is connected to the grasping device 11 and the installation device 12 respectively. The start and shutdown of the grasping device 11 and the installation device are controlled by the controller. The controller starts the grasping device 11, and the grasping device 11 moves from the original position to the working position. The grasping device 11 sends a request signal to the controller, and the controller sends a signal to the grasping device 11. The grasping device 11 collects the coordinates of the first installation hole of the battery module 16 according to the signal. The controller starts the installation device 12, and the installation device 12 moves from the original position to the working position. The installation device 12 sends a request signal to the controller, and the controller sends a signal to the installation device 12. The installation device 12 collects the second coordinates of the second installation hole at the installation position 172 according to the signal, and sends the second coordinates to the controller. The controller sends the second coordinates to the grasping device 11, and the installation device grasps the battery module 16 to the installation position 172 according to the first coordinate and the second coordinate. The installation device 12 installs and fixes the battery module 16 according to the second coordinate.

[0066] According to some embodiments of the present application, optionally, please continue to refer to Figure 1 The battery forming system 1 also includes a first transmission line 13 and a second transmission line 14. The first transmission line 13 transmits a plurality of battery module 16 transmission trays, and the battery module 16 transmission trays contain a plurality of battery modules 16; the second transmission line 14 transmits a plurality of battery transmission trays, and the battery transmission trays contain a lower shell 17, and a plurality of installation positions 172 are arranged on the lower shell 17; wherein the first transmission line 13 and the second transmission line 14 are arranged adjacent to each other, and the grasping device 11 and the installation device 12 are arranged on both sides of the second transmission line 14 opposite to each other.

[0067] The first transmission line 13 is provided with a battery module 16, the second transmission line 14 is provided with a lower shell 17, the first transmission line 13 and the second transmission line 14 are arranged adjacent to each other, and the grabbing device 11 is arranged adjacent to both the first transmission line 13 and the second transmission line 14, the installation device 12 is arranged adjacent to the second transmission line 14, and the grabbing device 11 and the installation device 12 are arranged oppositely on both sides of the second transmission line 14, so that it is convenient for the grabbing device 11 to grab the battery module 16 onto the lower shell 17, and the installation device 12 to fix the battery module 16 on the installation position 172 of the lower shell 17. Preferably, the first transmission line 13 and the second transmission line 14 are relatively vertical.

[0068] The first transmission line 13 is used to transmit the battery module 16 transmission tray, and each battery module 16 transmission tray is provided with a plurality of battery modules 16, that is, a plurality of battery modules 16 are transmitted on the first transmission line 13, and a plurality of battery transmission trays are transmitted on the second transmission line 14, and a lower shell 17 is contained on the battery transmission tray, and a plurality of installation positions 172 are provided on the lower shell 17, so that the battery module 16 and the lower shell 17 can be installed during the transmission process by the setting of the first transmission line 13 and the second transmission line 14.

[0069] According to some embodiments of the present application, the battery forming system 1 further includes a third transmission line 15, which is used to receive an abnormal battery module 16 grasped by the grasping device 11; wherein the third transmission line 15 is respectively arranged adjacent to the first transmission line 13 and the grasping device 11.

[0070] When it is detected that the battery module 16 is abnormal, the grabbing device 11 grabs the abnormal battery module 16 from the first transmission line 13 to the third transmission line 15. The third transmission line 15 is arranged adjacent to the first transmission line 13, so that the grabbing device 11 can grab and place it conveniently.

[0071] The third transmission line 15 is used to transmit abnormal battery modules 16. Before the grabbing device 11 grabs the battery module 16 to the lower shell 17 on the second transmission line 14, the battery module 16 will be tested first. If the battery module 16 is abnormal, the battery module 16 will be grabbed to the third transmission line 15 and the abnormal battery module 16 will be discarded to prevent the abnormal battery module 16 from being installed with the lower shell 17 and eventually forming a bad battery.

[0072] like Figure 2 Shown is a schematic diagram of the installation positions 172 in the lower shell 17 in the present application, which shows the positions of each installation position 172 and the preset serial numbers of each installation position 172. According to some embodiments of the present application, optionally, each installation position 172 on the lower shell 17 has a preset serial number, the preset serial numbers of each pair of installation positions 172 are not adjacent, and the installation position 172 with a forward preset serial number in each pair of installation positions 172 is away from the grasping device 11 relative to the other installation position, the grasping device 11 places the battery module 16 according to the preset serial number, and the installation device 12 fixes the battery module 16 according to the preset serial number.

[0073] In each pair of installation positions 172, the installation position 172 with a forward preset serial number is farther away from the grasping device 11 relative to the other installation position. The grasping device 11 places the battery module 16 according to the preset serial number, and the installation device 12 fixes the battery module 16 according to the preset serial number, that is, the grasping device 11 grasps and places each pair of battery modules 16 in an order from far to near. During the grasping process, when grasping the battery module 16, the grasping device 11 grasps one or two battery modules 16 from far to near according to the transmission order of the battery module 16 on the first transmission line 13, thereby completing the grasping process. Similarly, when the grasping device 11 places the battery module 16 on the second transmission line 14, it also places it in an order from far to near, thereby completing the grasping and placement of the battery module 16.

[0074] The lower shell 17 has a plurality of mounting positions 172, each mounting position 172 having a preset serial number. The grasping device 11 places the battery module 16 according to the preset serial number, and the preset serial numbers of two adjacent mounting positions 172 are not adjacent, and the mounting position 172 with the preset serial number in front of each pair is farther away from the grasping device 11 and closer to the mounting device 12 relative to the other, so that after the grasping device 11 grasps the first battery module 16 in each pair to the mounting position 172 with the preset serial number in front, it moves another battery module to another mounting position 172 close to the grasping device 11, so that the grasping device 11 makes room for the mounting device 12 to move, and the mounting device 12 can move the battery module 16 within a certain range. During installation, the grasping device 11 can grasp another battery module 16 to another installation position 172 with a later preset serial number. Since the preset serial numbers of two adjacent installation positions 172 are not adjacent, the installation device 12 and the grasping device 11 can work at the same time. When the grasping device 11 returns to the initial working position, the installation device 12 fixes and installs the second battery module 16, thereby improving the working efficiency of the grasping device 11 and the installation device 12, as well as the production efficiency of the battery. Moreover, each pair of installation positions 172 with a forward preset serial number is farther away from the grasping device 11 than the other one, and closer to the installation device 12, so that the installation devices 12 and the grasping devices 11 working at the same time will not interfere with each other due to the movable range of their respective robotic arms.

[0075] In this embodiment, if Figure 2 As shown, the preset serial numbers of the installation positions 172 of the lower housing 17 are paired in odd and even order and gradually increase, such as (01, 02), (03, 04) (05, 06) ... ... (23, 24). The gripping device 11 first places one battery module 16 at an odd position away from the gripping device 11, such as position 1, and the other at an even position close to the gripping device 11, such as position 2.

[0076] like Figure 3The figure is a schematic diagram of the structure of the grasping device 11. According to some embodiments of the present application, optionally, the grasping device 11 includes a first image acquisition device 111, and the first image acquisition device 111 is used to take a picture of the first mounting hole of the battery module 16, and obtain the first coordinate of the first mounting hole in the base coordinate system according to the picture of the first mounting hole.

[0077] The gripping device 11 includes a first image acquisition device 111, which is a visual industrial camera, arranged at the bottom of the gripping device 11 facing the battery module 16, and arranged opposite to the battery module 16, so as to facilitate photographing the battery module 16. There are two visual industrial cameras, which are respectively arranged corresponding to the first mounting holes of the two battery modules 16, and are used to photograph the two symmetrical first mounting holes of the battery module 16, and calculate the first coordinates of the two first mounting holes in the base coordinate system according to the photographed pictures.

[0078] The first picture acquisition device 111 sends a request to the controller, and the controller sends a signal to the first picture acquisition device 111 according to the request. The first picture acquisition device 111 photographs the battery module 16 according to the signal. If the photographing and the detection are normal, if the photograph is empty, the controller sends a signal to the first picture acquisition device 111, and the first picture acquisition device 111 goes to the next position to take pictures again until the battery module 16 is photographed.

[0079] According to some embodiments of the present application, the grasping device 11 also includes a detection device for detecting whether the battery module 16 is normal. The detection device is connected to the controller signal and sends the detection result to the controller; if the battery module 16 is normal, the controller controls the grasping device 11 to grasp the battery module 16 to the installation position 172 of the second transmission line 14; if the battery module 16 is abnormal, the controller controls the grasping device 11 to grasp the battery module 16 to the third transmission line 15.

[0080] The gripping device 11 includes a detection device, which is also arranged at the bottom of the gripping device 11 and is arranged opposite to the battery module 16 , so as to facilitate the detection of the battery module 16 .

[0081] The detection device is used to detect whether the battery module 16 is normal. If the battery module 16 is normal, the grasping device 11 grasps the battery module 16 to the installation position 172 of the lower shell 17 of the second transmission line 14, thereby further fixing the normal battery module 16 on the lower shell 17. If the detection device detects that the battery module 16 is abnormal, the grasping device 11 grasps the battery module 16 to the third transmission line 15 for waste discharge, thereby preventing the abnormal battery module 16 from being fixed to the lower shell 17 to finally form a battery.

[0082] like Figure 3As shown, according to some embodiments of the present application, the detection device includes a QR code scanner 112 and a battery tester, the QR code scanner 112 is used to scan the QR code on the battery module 16, the QR code scanner 112 is connected to the controller, and sends the scanning result to the controller; the voltage tester is used to detect the voltage of the battery module 16, and sends the detection result to the controller; if the QR code scanning result and the voltage detection result are normal, the controller controls the grasping device 11 to grasp the battery module 16 to the installation position 172 of the second transmission line 14; if the QR code scanning result and / or the voltage detection result are abnormal, the controller controls the grasping device 11 to grasp the battery module 16 to the third transmission line 15.

[0083] The grasping device 11 first moves to the first image acquisition device 111 corresponding to the first mounting hole to complete the shooting of the first mounting hole. At the same time, the QR code scanner 112 scans the QR code on the battery module 16, and then moves to the position corresponding to the voltage test piece and the positive and negative poles, so as to detect the voltage of the battery module 16.

[0084] A two-dimensional code is set on the surface of each battery module 16. The two-dimensional code is the identity tag of the battery module 16, which records the material code, voltage data and tightening quality data of the battery module 16. The grasping device 11 scans the two-dimensional code through the two-dimensional code scanning device, and detects the positive and negative voltages of the battery module 16 through the voltage test piece. If there is a problem with one of the two test results, the battery module 16 will be grasped to the waste discharge line through the grasping device 11. If there is no problem with both test results, the grasping device 11 is controlled to grasp the battery module 16 to the installation position 172 of the second transmission line 14.

[0085] like Figure 3 As shown, according to some embodiments of the present application, the gripping device 11 includes at least two grippers 114, each gripper 114 is used to grip a battery module 16, and each gripper 114 device is correspondingly provided with two voltage test pieces, and the two voltage test pieces are used to test the voltage between the positive and negative poles of the battery module.

[0086] The grasping device 11 includes at least two graspers 114 , each grasper 114 can grasp one battery module 16 , so that at least two battery modules 16 can be grasped at the same time, which improves work efficiency and saves time.

[0089] The mounting device 12 has a second picture acquisition device 121, which is used to take a picture of the second mounting hole of the upper shell of the second transmission line 14, so as to obtain the second coordinates of the second mounting hole according to the picture of the second mounting hole, wherein the second picture acquisition device 121 is a visual industrial camera, which is arranged at the bottom of the mounting device 12 facing the mounting position 172 and is arranged opposite to the mounting position 172, so as to facilitate the shooting of the second mounting hole at the mounting position 172.

[0090] The installation device 12 sends a request to the controller, and the controller sends a signal to the installation device 12 according to the request. The installation device 12 photographs the second installation holes at different installation positions 172 according to the signal of the controller. There are two visual industrial cameras, which are respectively arranged corresponding to the two second installation holes, and are used to photograph the two symmetrical second installation holes respectively, and calculate the second coordinates of the two second installation holes in the base coordinate system according to the photographed pictures, and send the second coordinates to the controller, and the controller sends the second coordinates to the grasping device 11, so that the grasping device 11 does not need to photograph the second installation holes, saving time and improving efficiency.

[0091] like Figure 4 As shown, according to some embodiments of the present application, the installation device 12 also includes at least one tightening gun 122, which is connected to the controller. The controller controls the tightening gun 122 to tighten the screws inserted into the first mounting hole and the second mounting hole according to the second coordinate to fix the battery module 16 to the installation position 172 of the lower shell 17.

[0092] The tightening gun 122 of the mounting device 12 serves as a fixing device of the mounting device 12 to the battery module 16 , and inserts the screws into the first mounting hole and the second mounting hole and tightens them, thereby fixing the battery module 16 and the lower shell 17 .

[0093] The battery module 16 has four first mounting holes, each mounting position 172 has four second mounting holes, and there are four tightening guns 122. Therefore, when the mounting device 12 fixes the battery module 16, the controller controls the nail feeder to deliver the screws to the gun heads of the four tightening guns 122 respectively. The four tightening guns 122 work simultaneously to tighten the battery module 16 together, thereby improving the tightening efficiency.

[0094] The battery forming system 1 provided in the present application includes a gripping device 11, an installation device 12, a controller, a first transmission line 13, a second transmission line 14 and a third transmission line 15. The first transmission line 13 transmits a battery module 16, the second transmission line 14 transmits a lower shell 17, and the third transmission line 15 is a waste discharge line.

The second coordinate in the reference system is determined, and the detected second coordinate is sent to the grasping device 11. The grasping device 11 is also used to detect the battery module 16. If the battery module 16 is detected to be normal, the grasping device 11 grasps the battery module 16 to the installation position 172 on the lower shell 17 of the second transmission line 14 according to the first coordinate and the second coordinate. The installation device 12 fixes the battery module 16 on the lower shell 17, thereby realizing the full automation of the battery forming system 1, saving labor costs, improving the efficiency of battery production, and improving safety performance.

[0095] Second, please refer to Figure 5 , as shown in the figure, the present application provides a battery forming method, comprising:

[0096] S101, collecting a first coordinate of a first mounting hole of a battery module in a base coordinate system;

[0097] The grasping device collects the first coordinate of the first mounting hole of the battery module in the base coordinate system. The first coordinate is the offset value of the first mounting hole of the battery module in the base coordinate system. The coordinates of the first coordinate in the base coordinate system are (X1, Y1, A1).

[0098] S102, collecting the second coordinate of the second mounting hole at the mounting position on the lower housing in the base coordinate system;

[0099] The installation device collects the second coordinate of the second mounting hole at the installation position on the lower shell in the base coordinate system, the second coordinate is the offset value of the second mounting hole at the installation position on the lower shell in the base coordinate system, and the coordinate of the first coordinate in the base coordinate system is (X2, Y2, A2), and the collected second coordinate is sent to the grasping device.

[0100] S103: grab a normal battery module to an installation position of the lower housing based on the first coordinate and the second coordinate, and fix the battery module at the installation position of the lower housing.

[0101] The grasping device grasps the normal battery module to the installation position of the lower shell according to the first coordinate and the second coordinate, and the installation device fixes the battery module at the installation position according to the second coordinate.

[0102] In the battery forming method, the coordinates of the first mounting hole of the battery module and the second mounting hole at the mounting position of the lower shell are collected by the grasping device and the installation device respectively in the base coordinate system. The coordinates collected by the grasping device and the installation device are both in the base coordinate system, so that the coordinates collected by the two can be shared. The second coordinates of the second mounting hole at the mounting position of the lower shell collected by the installation device can be shared with the grasping device for sharing, thereby reducing the work tasks of the grasping device, improving the operation efficiency of the grasping device, and improving the assembly cycle. The grasping device grasps the battery module from the first coordinate to the second coordinate according to the first coordinate and the second coordinate, thereby completing the entry of the battery module, so that the battery module is grasped from the initial position to the mounting position of the lower shell, and then the installation device installs the battery module to the mounting position through the second coordinate, thereby completing the entry and installation of the battery module. Therefore, through the mutual cooperation of the grasping device and the installation device, the battery module is placed on the mounting position of the lower shell and fixedly installed, thereby realizing a fully automatic grasping and installation process, and improving production efficiency.

[0103] like Figure 6 As shown, the present application provides another battery forming method, comprising:

[0104] S201, collecting a first coordinate of a first mounting hole of a battery module in a base coordinate system;

[0105] S202, collecting the second coordinate of the second mounting hole at the mounting position on the lower housing in the base coordinate system;

[0106] S203, checking whether the battery module is normal;

[0107] Before grabbing the battery module, it is necessary to detect whether the battery module is normal to prevent abnormal battery modules from being grabbed onto the lower shell to form a battery. The methods for detecting whether the battery module is normal include QR code detection and voltage detection. The QR code on the battery module is scanned and detected by a QR code scanner, and the voltage of the battery module is detected by a voltage tester.

[0108] S204, if the battery module is normal, grab the normal battery module to the installation position of the lower housing based on the first coordinate and the second coordinate;

[0109] If the QR code scanning result and the voltage detection result are both normal, the grabbing device is controlled to grab the battery module to the installation position of the second transmission line;

[0110] S205: If the battery module is abnormal, the battery module is grabbed onto the third transmission line.

[0111] If one of the two-dimensional code scanning result or the voltage detection result is abnormal, the grabbing device is controlled to grab the battery module onto the third transmission line.

[0112] In the battery forming method, the coordinates of the first mounting hole of the battery module and the second mounting hole at the mounting position of the lower shell are collected by the grasping device and the installation device respectively in the base coordinate system. The coordinates collected by the grasping device and the installation device are both in the base coordinate system, so that the coordinates collected by the two can be shared. The second coordinates of the second mounting hole at the mounting position of the lower shell collected by the installation device can be shared with the grasping device for sharing, thereby reducing the work tasks of the grasping device, improving the operation efficiency of the grasping device, and improving the assembly rhythm. The grasping device grasps the battery module from the first coordinate to the second coordinate according to the first coordinate and the second coordinate, thereby completing the entry of the battery module into the box, so that the battery module is grasped from the initial position to the mounting position of the lower shell, and then the installation device installs the battery module to the mounting position through the second coordinate, thereby completing the entry and installation of the battery module. The grasping device also detects the battery module. If it is detected that there is a problem with the battery module, it will be grasped to the third transmission line for waste discharge. If it is detected that there is no problem with the battery module, the battery module will be grasped to the mounting position on the second transmission line for installation. Thus, through the cooperation between the grasping device and the installation device, the battery module is placed on the installation position of the lower shell and fixedly installed, thereby realizing a fully automatic grasping and installation process and improving production efficiency.

[0113] like Figure 7 As shown, the present application provides another battery forming method, comprising:

[0114] S301, collecting a first coordinate of a first mounting hole of a battery module in a base coordinate system;

[0115] S302, collecting the second coordinate of the second mounting hole at the mounting position on the lower housing in the base coordinate system;

[0116] S303, checking whether the battery module is normal;

[0117] S304, if the battery module is normal, grab one or a pair of battery modules;

[0118] If the battery module is normal, the grabbing device grabs one or a pair of battery modules from the first conveying line.

[0119] S305, placing the first normal battery module at the installation position having the same preset serial number as the grabbing order according to the first coordinate of the first installation hole of the first battery module and the second coordinate of the second installation hole of the installation position having the same serial number as the grabbing order;

[0120] Then, the first battery module is placed on an installation position having a preset serial number which is the same as its grabbing order, wherein the lower shell has multiple installation positions corresponding to the battery modules, each installation position has a preset serial number, the preset serial numbers of each pair of installation positions are not adjacent, and the installation position with a forward preset serial number in each pair of installation positions is farther away from the grabbing device relative to the installation device, that is, the battery module is first placed at an installation position farther away from the grabbing device, and the placement order follows the principle of far first and near later.

[0121] S306, fixing the first battery module at the mounting position having the same preset serial number as the grabbing order in the lower housing according to the second coordinates of the second mounting hole at the mounting position having the same preset serial number as the grabbing order; placing the second normal battery module at the mounting position having the same preset serial number as the grabbing order according to the first coordinates of the first mounting hole of the second battery module and the second coordinates of the second mounting hole at the mounting position having the same preset serial number as the grabbing order;

[0122] The installation device then installs the battery module that has been placed close to the installation position. At the same time, the grasping device places another battery module at an installation position close to itself, so that the installation device and the grasping device work at the same time, saving time and improving efficiency.

[0123] S307, fixing the second battery module at the installation position having the same preset serial number as the grabbing order in the lower housing according to the second coordinates of the second installation hole at the installation position having the same preset serial number as the grabbing order.

[0124] The installation device then installs the next battery module, thereby completing the installation of the pair of battery modules, wherein a pair consists of two.

[0125] During the battery forming process, a plurality of installation positions are provided on the lower shell, each installation position has a preset serial number, and the grasping device places the battery module according to the preset serial number when placing the battery module, and the preset serial numbers of two adjacent installation positions are not adjacent, and the installation position with the front preset serial number of each pair is farther away from the grasping device and closer to the installation device relative to the other, so that after the grasping device grasps the first battery module in each pair to the installation position with the front preset serial number, the other battery module is moved closer to another installation position of the grasping device, and since the preset serial numbers of two adjacent installation positions are not adjacent, the grasping device makes room for the installation device to move. The installation device can install the battery module within a certain range, and the grasping device can grasp another battery module to another installation position with a preset serial number at the same time, so that the installation device and the grasping device can work at the same time, and when the grasping device returns to the initial working position, the installation device fixes and installs the second battery module, which improves the working efficiency of the grasping device and the installation device, as well as the production efficiency of the battery, and each pair of installation positions with preset serial numbers is far away from the grasping device and close to the installation device relative to the other, so that the installation device and the grasping device working at the same time will not interfere with each other due to the activity range of their respective robotic arms.
