The back contact solar cell assembly includes a back plate and a plurality of back contact cells formed on the back plate. The back contact cell may be an IBC solar cell or an MWT solar cell. The front surface of the battery piece is not provided with any electrode or only provided with the auxiliary grid line, so that the shading of the electrode is greatly reduced, and the efficiency of the solar battery is improved.

Fig. 1 illustrates a perspective view of a solar cell layout apparatus according to an embodiment of the present invention. Fig. 2 illustrates a top view of a solar cell layout apparatus according to an embodiment of the present invention. As shown in fig. 1 and 2, the solar cell typesetting device has at least one feeding area C, at least one transfer area D, and a typesetting station E. Each feeding area C includes a plurality of feeding stations C1 distributed along the conveying direction of the battery pieces a, and each transfer area D has a plurality of transfer stations D1 corresponding to the feeding stations C1.
Specifically, as shown in fig. 1 and 2, the plurality of transfer stations D1 and the plurality of loading stations C1 are disposed in parallel and are also distributed along the conveying direction of the battery sheet a.
As shown in fig. 1 and 2, the solar cell typesetting apparatus includes: at least one set of flipping structures 100, at least one typesetting mechanism 200, and a hot press mechanism 300. Each group of flipping structures 100 comprises a plurality of flipping mechanisms 110 corresponding to the transfer stations D1. Each turnover mechanism 110 is disposed between the corresponding feeding station C1 and the transfer station D1, so as to turn the battery piece a from the corresponding feeding station C1 to the transfer station D1, and the back contact surface of the battery piece a located at the transfer station D1 faces the direction of the plane where the back plate B is located. In practical application, the back plate B is positioned below the battery piece A, and the back contact surface of the battery piece A is turned downwards after being turned over.
As shown in fig. 1 and 2, at least one typesetting mechanism 200 is disposed between the corresponding transfer area D and the typesetting station E, so as to transfer the plurality of battery pieces a from the corresponding transfer area D to the corresponding typesetting position of the back plate B when the plurality of battery pieces a are located in the transfer area D and the back plate B is located in the typesetting station E.
As shown in fig. 1 and 2, the hot pressing mechanism 300 is disposed at the typesetting station E, and is used for hot pressing the plurality of battery pieces a at the corresponding typesetting positions of the back plate B.
As shown in fig. 2, the above-mentioned solar cell typesetting apparatus may further include a first conveying mechanism 400, where the first conveying mechanism 400 is configured to convey the cell a to the plurality of feeding stations C1. The plurality of loading stations C1 are distributed along the conveying direction of the first conveying mechanism 400. Specifically, the first conveying mechanism 400 may be a conveyor belt. The battery sheet a is placed on a conveyor belt, and is conveyed to the feeding station C1 by the conveyor belt. Since the back contact surface of the battery piece a is already printed with a plurality of conductive contacts when the first conveying mechanism 400 conveys the battery piece a, the back contact surface of the battery piece a conveyed by the first conveying mechanism 400 may deviate from the conveying surface of the first conveying mechanism 400 as shown in fig. 1 and 2. Specifically, as shown in fig. 2, the battery piece a is placed on the conveying surface of the first conveying mechanism 400, and the back contact surface of the battery piece a faces away from the conveying surface of the first conveying mechanism 400. In practical application, the back contact surface of the battery piece A faces upwards.
As shown in fig. 2, since the back plate B corresponds to the plurality of battery pieces a, two first conveying mechanisms 400 may be provided, and the two first conveying mechanisms 400 are respectively located at both sides of the typesetting station E, so as to simultaneously provide the typesetting station E with the plurality of battery pieces a. Of course, a plurality of feeding stations C1 may be disposed on the first conveying mechanism 400, so as to further increase the speed of providing the battery pieces a for the typesetting station E.
As shown in fig. 2, the above-mentioned solar cell typesetting apparatus may further include a second conveying mechanism 500, where the second conveying mechanism 500 is used to convey the back plate B to the typesetting station E. The second conveyor 500 may be a conveyor belt. The backboard B is placed on a conveyor belt, and is conveyed by the conveyor belt to the typesetting station E. In practical application, since the battery piece a needs to be mounted on the mounting surface of the back plate B, the mounting surface of the back plate B faces away from the conveying surface of the second conveying mechanism 500, that is, the mounting surface of the back plate B faces upward during conveying of the back plate B.
As shown in fig. 2, the number of the flipping mechanisms 110 and the typesetting mechanisms 200 may be set as desired. Each solar cell typesetting device can be provided with one turnover mechanism 110 and one typesetting mechanism 200, and can also be provided with a plurality of solar cell typesetting devices. The number of the turning mechanisms 110 and the typesetting mechanisms 200 may be set in a one-to-one correspondence manner, or may not be set in a correspondence manner, which is not limited.
In practical application, as shown in fig. 2, when the back contact solar cell module is produced, the first conveying mechanism 400 provides the feeding area C with the plurality of cells a, and the second conveying mechanism 500 provides the typesetting station E with the back plate B. The plurality of battery pieces a in the loading area C are distributed along the conveying direction of the first conveying mechanism 400. The overturning structure 100 firstly overturns the plurality of battery pieces A in the feeding area C to the transferring area D at the same time, and the back contact surface of the battery piece A positioned at the transferring station D1 faces downwards. Next, the layout mechanism 200 transfers the plurality of battery pieces a in the transfer area D to the corresponding layout positions of the back plate B. Finally, the hot pressing mechanism 300 hot presses the plurality of battery pieces a at the corresponding typesetting positions of the back plate B.
As shown in fig. 1 and 2, each turnover mechanism 110 is used to turn the battery piece a from the corresponding loading station C1 to the corresponding transferring station D1. In general, when the battery piece a is conveyed by the conveying mechanism, the back contact surface of the battery piece a is preferably upward, that is, the back contact surface is away from the conveying surface of the conveying mechanism, so as to avoid damaging the conductive material of the back contact surface of the battery piece a after the conveying surface of the conveying mechanism contacts with the back contact surface of the battery piece a. When the back contact solar cell module is produced, the turnover mechanism 110 turns the transferred plurality of cell pieces a from the corresponding feeding station C1 to the transfer station D1, so that the back contact surface of the cell piece a located in the transfer station D1 faces the direction of the plane where the back plate B is located. Next, the imposition mechanism 200 transfers the battery cells a from the respective transfer stations D1 to the respective imposition positions of the back plates B. Therefore, when the battery piece A is mounted on the backboard B, typesetting is performed through the typesetting mechanism 200, so that offset between the back contact battery piece A and the backboard B can be reduced, automation of the back contact solar cell module is realized, production efficiency of the back contact solar cell module is improved, and production cost is reduced.
In addition, as shown in fig. 1 and 2, each of the feeding areas C includes a plurality of feeding stations C1 distributed along the conveying direction of the battery pieces a, each of the transfer areas D has a plurality of transfer stations D1 corresponding to the feeding stations C1, and each of the sets of flipping structures 100 includes a plurality of flipping mechanisms 110 corresponding to the transfer stations D1. Based on this, the overturning structure 100 can overturn the plurality of battery pieces a simultaneously, and typeset the plurality of battery pieces a at the corresponding typesetting positions of the backboard B through the typesetting mechanism 200 simultaneously, so as to improve typesetting efficiency.
Furthermore, as shown in fig. 1 and 2, the solar cell module manufacturing apparatus further includes a heat pressing mechanism 300 disposed at the typesetting station E, where the heat pressing mechanism 300 is configured to heat-press the plurality of cells a at the corresponding typesetting positions of the back plate B. After the typesetting mechanism 200 typesets the plurality of battery pieces a at the corresponding typesetting positions of the back plate B, the hot pressing mechanism 300 hot presses the plurality of battery pieces a on the back plate B. In the process of hot pressing the battery pieces a by the hot pressing mechanism 300, the typesetting mechanism 200 can grasp the next batch of battery pieces a, so that the typesetting process and the hot pressing process are separately performed, the production beat is accelerated, and the typesetting efficiency is further improved.
As one possible implementation manner, the solar cell module manufacturing apparatus may further include: the system comprises a plurality of first image collectors corresponding to the transfer stations, at least one second image collector and a controller which is respectively communicated with the first image collectors, the second image collectors and the typesetting mechanism.
As shown in fig. 2, each first image collector 600 is configured to collect an image of the back contact surface of the battery piece a when the battery piece a is located at the corresponding transfer station D1. Specifically, the plurality of first image collectors 600 are disposed parallel to the plurality of transfer stations D1, that is, the plurality of first image collectors 600 are also distributed along the conveying direction of the battery sheet a. The first image collector 600 may be an industrial camera, but is not limited thereto. Each second image collector 700 is configured to collect layout images of the layout positions of the backboard B when the backboard B is located at the layout station E. The second image collector 700 may be an industrial camera, but is not limited thereto. The controller controls the typesetting mechanism 200 to transfer the plurality of battery pieces A to the corresponding typesetting positions of the backboard B according to the images of the back contact surfaces of the battery pieces A and typesetting images.
Specifically, as shown in fig. 2, when the back contact solar module is produced, the turnover mechanism 110 turns the back contact surface of the battery piece a at the transfer station D1, so that after the back contact surface of the battery piece a faces downward, the first image collector 600 is controlled to collect the image of the back contact surface of the battery piece a on the corresponding transfer station D1, and the image of the back contact surface of the battery piece a is sent to the controller; the second image collector 700 is controlled to collect typesetting images of the backboard B, and the typesetting images of the backboard B are sent to the controller; the controller controls the typesetting mechanism 200 to typeset the back contact surface of the battery piece A at the corresponding typesetting position of the back plate B according to the image of the back contact surface of the battery piece A and the typesetting image of the back plate B.
As shown in fig. 2, after the turnover mechanism 110 places the battery piece a at the corresponding transfer station D1, the corresponding first image collector 600 collects the image of the back contact surface of the battery piece a when the battery piece a is located at the corresponding transfer station D1. The second image collector 700 collects the typesetting image of the typesetting position of the backboard B when the backboard B is located at the typesetting station E. The controller controls the typesetting mechanism 200 to typeset the plurality of battery pieces A at the corresponding typesetting positions of the backboard B according to the images of the back contact surfaces of the battery pieces A and typesetting images. Based on this, after conveying battery piece A and backplate B, the controller is typeset a plurality of battery pieces A in backplate B's corresponding typesetting position according to battery piece A back contact surface's image and typesetting image control typesetting mechanism 200 of typesetting position, even battery piece A and backplate B take place the skew and also do not receive the influence in the conveying, need not accurate backplate B and battery piece A's position when conveying, the device requirement of conveying battery piece A and backplate B is low, and make battery piece A and backplate B accurate to the position, the yields of back contact solar module has greatly been improved, and have stronger adaptability and flexibility to production environment and production condition, be adapted to various subassembly models.
In an alternative, the at least one first image collector may be provided at the transfer station. The first image collectors are arranged in one-to-one correspondence with the transfer stations. The first image collector can collect images of the back contact surfaces of the battery pieces of the corresponding rotating stations.
In an alternative manner, fig. 3 illustrates a schematic diagram of a typesetting mechanism in an embodiment of the present invention. As shown in fig. 3, the at least one second image collector 700 may be provided at one end of the corresponding typesetting mechanism 200. The typesetter can drive the second image collector 700 to move, when the second image collector 700 is close to the corresponding typesetting position of the battery piece A, the second image collector 700 can collect corresponding typesetting position images, so that the second image collector 700 can conveniently and accurately collect different typesetting position images, when the second image collector 700 is prevented from being arranged above the backboard B, if the middle area of the backboard B is bulged, the image collected by the second image collector 700 is a bulged projection area and is inconsistent with the image of the actual typesetting position, and the position of the battery piece A mounted on the backboard B is caused to deviate.
As a possible implementation, as shown in fig. 1 and 2, the hot press mechanism 300 may be a hot press horizontal mechanism, where the hot press horizontal mechanism has a plurality of hot press stations corresponding to typesetting positions. Based on the above, the hot-pressing horizontal arrangement mechanism can simultaneously hot-press the battery pieces A at a plurality of typesetting positions corresponding to the hot-pressing stations.
Specifically, as shown in fig. 1, the hot pressing mechanism 300 may include a hot pressing plate, a hot pressing driving mechanism for driving the hot pressing plate to perform hot pressing of the battery cells a, and a moving driving device for driving the hot pressing plate to move. The hot pressing stations are arranged on one side of the hot pressing plate facing the backboard B corresponding to the typesetting positions. In general, the hot platen is located above the back plate B, and therefore, the hot press station is located below the hot platen.
As shown in fig. 1, the hot pressing plate may extend along one side of the back plate B, and the moving driving means may include a hot pressing moving means and a hot pressing lifting means. The hot pressing mobile device is used for driving the hot pressing plate to move, and the moving direction of the hot pressing plate is perpendicular to the extending direction of the hot pressing plate, so that the hot pressing plate can be sequentially positioned above each part of the backboard B, the battery piece A on each part of the backboard B is hot-pressed, and when hot pressing is not needed, the hot pressing plate can be moved to the side surface of the backboard B, and the phenomenon that the hot pressing plate affects the typesetting mechanism 200 is avoided. The hot pressing lifting device is used for driving the hot pressing plate to lift so that the hot pressing plate is contacted with or separated from the battery piece A.
In one example, a plurality of hot press stations may be distributed below the hot press plate along a straight line such that the hot press mechanism may simultaneously hot press a plurality of battery cells on the same straight line.
In another example, a plurality of hot press stations are distributed in a matrix under the hot press plate so that the hot press mechanism can simultaneously hot press more battery cells.
As a possible implementation manner, as shown in fig. 2 and 3, the at least one typesetting mechanism 200 may include a first moving device 210 and a plurality of first vacuum suction devices 220 located at one end of the first moving device 210, where each first vacuum suction device 220 is configured to suction a battery piece a, and the first moving device 210 is configured to transfer the plurality of battery pieces a from the corresponding transfer area D to the corresponding typesetting position of the back plate B.
In an example, the plurality of first vacuum adsorption devices can be independently controlled, and when the number of the battery pieces to be adsorbed is less than that of the first vacuum adsorption devices, the idle vacuum adsorption devices can be controlled to be not operated, so that the battery pieces with the corresponding number can be adsorbed according to the requirement, and the application range is wide.
Specifically, as shown in FIG. 3, a plurality of first vacuum suction devices 220 may be matched to a plurality of transfer stations D1 within the transfer area D. When the typesetting mechanism 200 moves to the transfer area D, the plurality of first vacuum suction devices 220 correspond to the plurality of transfer stations D1, so that the typesetting mechanism 200 can suck the plurality of battery pieces a in the transfer area D.
In practical application, as shown in fig. 3, when the typesetting mechanism 200 transfers a plurality of battery pieces a, the first moving device 210 moves a plurality of first vacuum adsorption devices 220 to the transfer area D, each first vacuum adsorption device 220 corresponds to a battery piece a at the transfer station D1, and the first vacuum adsorption device 220 adsorbs the battery piece a through the front surface of the battery piece a. Next, the plurality of battery pieces a are simultaneously transferred to the corresponding typesetting positions of the back plate B by the first moving device 210.
In an alternative manner, the first vacuum adsorption device may include a first vacuum adsorption plate disposed at one end of the first moving device, and a first adsorption driving mechanism for driving the first vacuum adsorption plate to adsorb the battery sheet. When the battery piece is adsorbed, the first adsorption driving mechanism drives the first vacuum adsorption plate to adsorb the battery piece; after the battery piece is moved to the destination by the first moving device, the first vacuum adsorption driving mechanism stops driving the first vacuum adsorption plate, so that the battery piece is placed at the destination.
In one example, when the plurality of first vacuum adsorption devices are independently controlled, the first vacuum adsorption device may further include a lifting device through which the first vacuum adsorption plate is disposed at one end of the first moving device. When adsorbing or placing the battery piece, elevating gear makes first vacuum adsorption board to backplate one side protrusion, avoids adsorbing or placing the battery piece in-process, and other first vacuum adsorption device and the battery piece contact on the backplate.
In an alternative, as shown in fig. 1, the first moving device 210 may be an industrial robot, and a plurality of first vacuum suction devices 220 are disposed at one end of the industrial robot.
In another alternative, fig. 4 illustrates a perspective view of another solar cell layout apparatus according to an embodiment of the present invention.

As shown in fig. 4 and 5, the first moving device 210 may include a guide frame 211, at least one moving seat 212 slidably provided on the guide frame 211, and at least one first driving mechanism for driving the moving seat 212 to move; a plurality of first vacuum suction devices 220 are provided on the corresponding moving seats 212. The first driving mechanism may be a telescopic motor or a cylinder, but is not limited thereto.
As shown in fig. 4, the guiding frame 211 is disposed above the back plate B, and the plurality of first vacuum suction devices 220 can be driven by the moving base 212 to move for transferring the battery pieces a.
As shown in fig. 4, a plurality of first vacuum suction devices 220 are provided on the corresponding moving base 212, and the first driving mechanism drives the moving base 212 to linearly move along the guide frame 211. In this way, when the first moving device 210 moves the plurality of battery pieces a, the plurality of battery pieces a move in a straight line, thereby reducing the deviation generated by moving the battery pieces a.
In one example, as shown in fig. 5, the at least one typesetting mechanism 200 may further include a first posture adjustment mechanism 230, and the plurality of first vacuum suction devices 220 may be connected to one end of the first moving device 210 through the first posture adjustment mechanism 230. The first posture adjustment mechanism 230 can adjust the battery piece a adsorbed on the plurality of first vacuum adsorption devices 220, so that the battery piece a and the back plate B are aligned accurately.
Specifically, as shown in fig. 5, the first posture adjustment mechanism 230 may be a multi-degree-of-freedom angle adjustment mechanism. The first posture adjustment mechanism 230 adjusts the battery pieces a adsorbed by the plurality of first vacuum adsorption devices 220 to a horizontal state and drives the battery pieces a to rotate. The first posture adjustment mechanism 230 adjusts the battery pieces a adsorbed by the plurality of first vacuum adsorption devices 220 to be horizontal, so that the connection process of the battery pieces a and the backboard B is more stable and accurate. The first posture adjustment mechanism 230 can drive the battery piece a to rotate, so that the battery piece a and the back plate B are aligned accurately.
As a possible implementation manner, as shown in fig. 4, the solar cell typesetting apparatus further includes a mobile platform 800 and at least one string arranging mechanism 900. The moving platform 800 is provided between the transfer area D and the at least one typesetting mechanism 200 for reciprocating movement between the transfer area D and the typesetting station E.
Fig. 6 illustrates a schematic diagram of a mobile platform in an embodiment of the invention. As shown in fig. 6, the mobile platform 800 has a stringing area 810 for carrying a plurality of battery cells a, the stringing area 810 including a stringing station 811 having a plurality of corresponding battery cells a.
Fig. 7 illustrates a schematic diagram of a string arranging mechanism in an embodiment of the present invention. Fig. 8 illustrates a schematic connection diagram of the string arranging mechanism and the turning mechanism in the embodiment of the invention. As shown in fig. 7 and 8, each of the stringing mechanisms 900 is provided at the transfer area D for transferring the plurality of battery pieces a from the corresponding transfer area D to the stringing area 810 of the moving platform 800 when the plurality of battery pieces a are located at the transfer area D. The imposition mechanism 200 is used to transfer a plurality of battery cells a from the stringing area 810 to corresponding imposition locations of the back plate B.
As shown in fig. 6, the mobile platform 800 has a stringing area 810 for carrying a plurality of battery cells a, the stringing area 810 including a stringing station 811 having a plurality of corresponding battery cells a. In the case of producing the back contact solar cell module, as shown in fig. 4, after the turning structure 100 turns the plurality of battery pieces a to the transfer area D, as shown in fig. 8, the string arrangement mechanism 900 transfers the plurality of battery pieces a from the corresponding transfer area D to the string arrangement area 810 of the moving platform 800, and strings the plurality of battery pieces a before the string arrangement mechanism 200 transfers the battery pieces a. Next, the moving platform 800 moves the plurality of battery pieces a to the typesetting station E, and the typesetting mechanism 200 transfers the plurality of battery pieces a from the string arranging area 810 to the corresponding typesetting positions of the back plate B. Therefore, the mobile platform 800 can move the battery piece a near the typesetting mechanism 200, and the typesetting mechanism 200 does not need to transfer the battery piece a from the transfer area D, so that the working stroke of the typesetting mechanism 200 is reduced, and the typesetting efficiency is improved. In addition, the number of the battery pieces a moved by the moving platform 800 each time can be multiple times of the number of the battery pieces a rotated by the typesetting mechanism 200, so that the number of times of moving the battery pieces a by the moving platform 800 is reduced, and the energy consumption is saved.
In an alternative manner, as shown in fig. 1 to 5, the plurality of battery pieces a transferred by the typesetting mechanism 200 at a time are distributed in a matrix of m×n, where m and n are integers. Wherein m is more than or equal to 1, and n is more than 1; or, m is more than 1, and n is more than or equal to 1. That is, the imposition mechanism 200 transfers a single row, a single column, or a plurality of rows and columns of battery pieces a at a time.
As shown in fig. 5, when the typesetting mechanism 200 includes the plurality of first vacuum suction devices 220, the plurality of first vacuum suction devices 220 are distributed in a matrix of m×n each time the plurality of battery pieces a transferred are distributed in a matrix of m×n.
As shown in fig. 6, a plurality of stringing stations 811 are distributed in a matrix of a×b, with a and b each being an integer. Wherein a is greater than or equal to m, and b is greater than or equal to n. The stringing station 811 on the mobile platform 800 is at least equal to the number of battery pieces a transferred by the typesetting mechanism 200 at a time.
For example, as shown in fig. 1, m=1, n=6, and the imposition mechanism 200 may transfer 6 battery pieces a at a time. In one example, a=1, b=6. In practical application, the turnover structure 100 includes 6 turnover mechanisms 110, and the turnover structure 100 turns over 6 battery pieces a at a time, and the string arrangement mechanism 900 transfers 6 battery pieces a at a time. Based on this, the turnover structure 100 turns over the primary battery pieces a, the string arrangement mechanism 900 transfers the primary battery pieces a, the moving platform 800 transfers the primary battery pieces a to the typesetting mechanism 200, and the typesetting mechanism 200 transfers the primary battery pieces a to the back plate B.
In another example, a=6, b=6. In practical application, the turnover structure comprises 6 turnover mechanisms, the turnover structure turns over 6 battery pieces each time, and the string arranging mechanism transfers 6 battery pieces each time. Based on this, flip structure upset six times battery piece, row cluster mechanism transfer six times battery piece, and moving platform is once battery piece to typesetting mechanism transportation, and typesetting mechanism is six times battery piece to the backplate transportation.
As another example, as shown in fig. 5, m=3, n=8, and the layout mechanism 200 may transfer 24 battery pieces a at a time. In one example, as shown in fig. 6, a=3, b=8. In practical application, the turnover structure 100 includes 8 turnover mechanisms 110, and the turnover structure 100 turns over 8 battery pieces a at a time, and the string arrangement mechanism 900 transfers 8 battery pieces a at a time. Based on this, the turnover structure 100 turns over the three-time battery pieces a, the string arrangement mechanism 900 transfers the three-time battery pieces a, the moving platform 800 transfers the one-time battery pieces a to the typesetting mechanism 200, and the typesetting mechanism 200 transfers the one-time battery pieces a to the back plate B.
As shown in fig. 4 to 8, the plurality of turnover mechanisms 110 are distributed along the conveyance direction of the battery pieces a, so that the plurality of battery pieces a in the transfer area D are distributed along a straight line.

The embodiment of the invention also provides manufacturing equipment of the solar cell module, which comprises the solar cell typesetting equipment. The beneficial effects of the manufacturing equipment of the solar cell assembly are the same as those of the typesetting equipment of the solar cell, and the description is omitted here.
The embodiment of the invention also provides a typesetting method of the solar cell, which is applied to the typesetting equipment of the solar cell. The typesetting method of the solar cell comprises the following steps:
step S100, controlling at least one group of turnover structures, wherein each group of turnover structures comprises a plurality of turnover mechanisms which are in contact with the back contact surfaces of the battery pieces, and turning the battery pieces from the corresponding feeding stations to the transfer stations so that the back contact surfaces of the battery pieces positioned at the transfer stations face the direction of the plane where the backboard is positioned;
step S200, controlling at least one typesetting mechanism to be in contact with the front surfaces of the plurality of battery pieces, and transferring the plurality of battery pieces from the corresponding transfer areas to the corresponding typesetting positions of the backboard;
and step S300, controlling a hot pressing mechanism to hot press the plurality of battery pieces at the corresponding typesetting positions of the backboard.
As a possible implementation manner, when the solar cell typesetting device includes the first image collector, the second image collector, and the controller, step S200 includes:
Step S210, controlling at least one first image collector to collect images of the back contact surfaces of the battery pieces on the corresponding transfer stations, and sending the images of the back contact surfaces of the battery pieces to a controller.
And controlling at least one second image collector to collect typesetting images of typesetting positions of the backboard, and sending the typesetting images to the controller.
Step S220, the controller controls the typesetting mechanism to transfer the plurality of battery pieces to corresponding typesetting positions of the backboard according to the images of the back contact surfaces of the battery pieces and the typesetting images.
It should be noted that in step S210, the "control at least one first image collector collects the image of the back contact surface of the battery piece on the corresponding transfer station, and sends the image of the back contact surface of the battery piece to the controller. And controlling at least one second image collector to collect typesetting images of typesetting positions of the backboard, and sending the typesetting images to the controller. "not in sequential order," may also be performed simultaneously.
In an alternative manner, the step S220 may include:
step S221: and comparing the image of the back contact surface of the battery piece with a reference battery piece image to determine the offset parameter of the battery piece. And comparing the typesetting image with the reference typesetting image to determine the offset parameters of the typesetting position.
Step S222: and the controller determines the offset parameters of the battery pieces at the corresponding typesetting positions of the backboard according to the offset parameters of the battery pieces and the offset parameters of the typesetting positions.
Step S223: and the controller controls the typesetting mechanism to transport the battery pieces to the corresponding typesetting positions of the backboard according to the offset parameters.

In practical application, typesetting logic can be set first, and each typesetting mechanism typesets each battery piece in the corresponding typesetting position in sequence. Thus, each cell has theoretical coordinates on the back plate.
After the battery pieces are conveyed and turned over, the positions of the battery pieces are deviated from preset positions. After the backboard is conveyed, typesetting positions on the backboard are offset from preset positions.
Thus, the reference cell image may be preset. For example, the shooting angle of the first image collector is fixed every time an image is collected, so that an image with a battery piece which is not shifted is used as a reference battery piece image. After the image of the back contact surface of the battery piece is acquired, if the battery piece is offset in the conveying and overturning processes, the position of the battery piece at the transfer station is different from the preset position, and the image of the back contact surface of the battery piece can be compared with the image of the reference battery piece to determine the offset parameter of the battery piece. If the battery piece is not shifted, the shift parameter is 0.
The reference layout image may also be preset. For example, the shooting angle of the second image collector is fixed every time the second image collector collects images, so that the images with the non-offset typesetting positions of the backboard are used as reference typesetting images. After the typesetting images of the actual typesetting positions are acquired, if the backboard shifts in the transmission process, so that the typesetting positions are different from the preset positions, and the shifting parameters of the typesetting positions can be determined by comparing the typesetting images with the reference typesetting images. If the typesetting position is not shifted, the offset parameter is 0.
And finally, determining the offset parameters of the battery pieces at the corresponding typesetting positions of the backboard according to the offset parameters of the battery pieces and the offset parameters of the typesetting positions, so as to adjust the theoretical coordinates of the battery pieces on the backboard, obtain the actual coordinates of the battery pieces on the backboard, and accurately align the battery pieces with the typesetting positions.

When the first mark point is provided on the first insulating portion, the first mark point may be a conductive material. It is noted that the conductive material located on the first insulating portion is non-conductive.
