The battery piece printing mechanism 40 is located above the battery piece adjusting and conveying mechanism 20, and is used for performing printing processing on the battery pieces with the adjusted positions.

The cell adjusting and conveying mechanism 20 is used for receiving the cell to be printed from the cell input mechanism 60, completing the position adjustment of the cell, moving the cell with the adjusted position to the cell printing mechanism for printing, and placing the cell to the cell output mechanism 60 after the printing is finished.

The cell output mechanism 60 is located at a subsequent station of the cell adjusting and conveying mechanism 20, and is configured to output the printed cell, that is, convey the printed cell located in the cell adjusting and conveying mechanism 20 to a subsequent station.

It can be seen that, by providing the cell adjusting and conveying mechanism 20, the present invention realizes automatic adjustment of the position of the cell before performing the printing operation, thereby improving the printing efficiency and the printing quality of the cell.

Optionally, as shown in fig. 1 to 3, the battery piece printing apparatus in this embodiment further includes a first detection mechanism 30 and a second detection mechanism 50. Wherein: the first detection mechanism 30 is disposed above the cell adjusting and conveying mechanism 20, the first detection mechanism 30 is configured to detect position information of a cell to be printed on the cell adjusting and conveying mechanism 20, and the cell adjusting and conveying mechanism 20 completes position adjustment of the cell to be printed based on the position information of the cell to be printed, which is acquired by the first detection mechanism 30. The second detection mechanism 50 is disposed above the battery piece output mechanism 60, and the second detection mechanism 50 is used for detecting whether the printed battery piece on the battery piece output mechanism 60 is qualified.

Optionally, the first translation driving mechanism 22 and the lifting driving mechanism 23 may both adopt an existing driving mechanism composed of a guide rail, a ball screw assembly and a driving motor, and can precisely control the displacement distance.

It can be seen that under the driving of the first translation driving mechanism 22, the adjusting platform 24 can move the battery piece to be printed to the printing station, and move the battery piece after the printing is completed out of the printing station. Under the drive of the lifting driving mechanism 23, the adjusting platform 24 drives the battery plate to lift in the vertical direction so as to drive the battery plate to lift synchronously, for example, when the battery plate moves to the printing station, the lifting driving mechanism 23 drives the adjusting platform 24 to lift, so that the battery plate contacts with the battery plate printing mechanism 40 to complete printing. After the printing of the battery piece is completed, the lifting driving mechanism 23 drives the adjusting platform 24 to descend and return to the original position.

In order to transfer the battery piece to be printed on the battery piece input mechanism 10 to the adjusting platform 24 smoothly and transfer the battery piece with printing completed on the adjusting platform 24 to the battery piece output mechanism 60 smoothly. Alternatively, as shown in fig. 4, each of the cell input mechanism 10 and the cell output mechanism 60 includes a first conveyor belt 11 and a second conveyor belt 12 arranged side by side for carrying a cell, and the cell input mechanism 10 and the cell output mechanism 60 are located on the same axis.

Correspondingly, the bearing plate 243 of the adjusting platform 24 is provided with a first groove 244 and a second groove 245 matched with the first conveyor belt 11 and the second conveyor belt 12.

As shown in fig. 4, when the adjusting platform 24 needs to receive the battery piece to be printed from the battery piece input mechanism 10, the lifting driving mechanism 23 first drives the adjusting platform 24 to descend, and then the first translation driving mechanism 22 drives the adjusting platform 24 to translate towards the battery piece input mechanism 10 until the adjusting platform 24 moves below the battery piece input mechanism 10. Then, the lifting driving mechanism 23 drives the adjusting platform 24 to ascend to a first predetermined height, in the process, the first conveyor belt 11 and the second conveyor belt 12 of the cell input mechanism 10 sink into the first groove 244 and the second groove 245 of the adjusting platform 24, respectively, the cell loaded on the cell input mechanism 10 is lifted away from the cell input mechanism 10 by the carrying plate, that is, the cell to be printed is transferred from the cell input mechanism 10 to the adjusting platform 24.

After the printing of the battery piece is completed, the lifting driving mechanism 23 drives the adjusting platform 24 to descend and return to the original position, so that the first groove 244 and the second groove 245 of the adjusting platform 24 are at the same height as the first conveying belt 11 and the second conveying belt 12 of the battery piece output mechanism 60. Then, the first translation driving mechanism 22 drives the adjusting platform 24 to move towards the cell output mechanism 60, in the process, the first conveyor belt 11 and the second conveyor belt 12 of the cell output mechanism 60 are respectively inserted into the first groove 244 and the second groove 245 of the adjusting platform 24. Then, the lifting driving mechanism 23 drives the adjusting platform 24 to descend to a second predetermined height, in the process, the first conveying belt 11 and the second conveying belt 12 of the cell output mechanism 60 float upwards to form the first groove 244 and the second groove 245, respectively, the cell on the adjusting platform 24 falls onto the first conveying belt 11 and the second conveying belt 12 of the cell output mechanism 60, that is, the printed cell is transferred from the adjusting platform 24 to the cell output mechanism 60.

In order to make the structure of the utility model more compact and the performance more stable. Alternatively, as shown in fig. 4, in the present embodiment, the cell input mechanism 10 is connected to a first end of the first mounting bracket 21, and the cell output mechanism 60 is connected to a second end of the first mounting bracket 21, that is, the cell input mechanism 10, the cell output mechanism 60 and the cell adjusting and conveying mechanism 20 are integrated on the same mounting bracket.

As shown in fig. 4, in some embodiments, the cell adjusting and conveying mechanism 20 is provided with two sets of adjusting and conveying portions, which alternately receive and position-adjust the cells, move the adjusted cells to the cell printing mechanism 40 for printing, and place the cells to the cell output mechanism 60 after printing.

Because two sets of adjustment conveying parts all are provided with lift actuating mechanism 23, under the regulation of respective lift actuating mechanism 23, can realize: in the operating state, the adjusting platforms 24 of the two groups of adjusting conveying parts are at different heights in the vertical direction, so that the adjusting platforms 24 of the two groups of adjusting conveying parts are prevented from colliding and interfering.

Alternatively, as shown in fig. 6 and 7, the cell printing mechanism 40 includes a second mounting bracket 41, a second translation driving mechanism 42, a screen plate assembly 43, a third translation driving mechanism 44, and a printing material coating assembly 45, wherein: a second translation drive mechanism 42 is mounted on the second mounting bracket 41, the screen assembly 43 is connected to a drive end of the second translation drive mechanism 42, and the second translation drive mechanism 42 drives the screen assembly 43 to translate along a first horizontal direction perpendicular to the conveying direction of the cell adjusting conveyor 20. A third translation drive mechanism 44 is mounted on the second mounting bracket 41 above the screen assembly 43, and a printing material application assembly 45 is coupled to a drive end of the third translation drive mechanism 44 and contacts the screen assembly 43, the third translation drive mechanism 44 translating the printing material application assembly 45 in a second horizontal direction parallel to the feed direction of the cell adjustment feed mechanism 20 to apply printing material to the screen assembly. The printing material may be conductive paste, grid line paste, etc. according to the specific printing purpose.

Alternatively, the second translation driving mechanism 42 and the third translation driving mechanism 44 may be any known driving mechanism including a slide rail, a ball screw, and a driving motor.

Optionally, the cell adjusting and conveying mechanism 20 and the cell printing mechanism 40 cooperate to complete the printing of the cell according to the following processes:

after the adjustment conveying part of the cell adjustment conveying mechanism 20 obtains the cell to be printed from the cell input mechanism 10, the cell to be printed is moved to the printing station located below the cell printing mechanism 40 (the cell is stopped at a predetermined position, and the adjustment of the cell in the direction parallel to the conveying line is completed).

Subsequently, the screen assembly 43 of the cell printing mechanism 40 is driven by the second translation driving mechanism 42 to translate in the first horizontal direction, so that the screen assembly 43 is aligned with the projection of the cell to be printed below (i.e. the adjustment of the position of the cell perpendicular to the conveying direction is relatively completed), and then the conveying portion is adjusted to lift the cell to be printed to contact and attach with the screen assembly 43 of the cell printing mechanism 40. Before the battery cell is attached to the battery cell printing mechanism 40, the rotating motor 242 adjusts the angle of the battery cell in the horizontal plane so that the battery cell is aligned with the screen. Subsequently, the printing material coating assembly 45 of the cell printing mechanism 40 is translated along the second horizontal direction, so that the printing material on the printing material coating assembly 45 is uniformly coated on the screen assembly 43, and the printing material coated on the screen assembly 43 permeates into the cell to be printed through the meshes on the screen assembly 43, thereby completing the printing of the cell.

And then, the adjusting and conveying part drives the printed battery piece to descend and return, and the printed battery piece is conveyed to the battery piece output mechanism 60 in a translation mode, and the printed battery piece is output to the next station by the battery piece output mechanism 60. Therefore, the accurate adjustment of the positions of the battery pieces in two mutually perpendicular directions and the angle of the horizontal plane is realized, and the printing precision is greatly improved.

Second embodiment

The battery piece printing device provided by the present embodiment is basically the same as the battery piece printing device provided by the first embodiment in structure and operation process, and the main differences exist in that: the number of the adjusting and conveying parts of the cell adjusting and conveying mechanism 20 in this embodiment is different, and a cell arranging mechanism for pre-arranging the cells is further provided in this embodiment.

For brevity, the present specification only provides a specific description of the different technical contents of the battery printing apparatus in the present embodiment with respect to the battery printing apparatus provided in the first embodiment, and please refer to the related description of the first embodiment directly for the remaining same technical contents.

As shown in fig. 8 to 10, in order to further improve the printing efficiency of the battery piece printing device, in the present embodiment, the adjusting and conveying units of the battery piece adjusting and conveying mechanism 20 are provided in four groups, the four groups of adjusting and conveying units alternately receive the battery pieces and adjust the positions of the battery pieces, and the battery pieces with the adjusted positions are moved to the battery piece printing mechanism 40 for printing, and after the printing is finished, the battery pieces are placed to the battery piece output mechanism 60. Compared with the first embodiment, the number of the adjusting and conveying parts is doubled, and therefore, the printing efficiency of the battery piece printing device in the embodiment can be correspondingly improved by nearly one time.

As in the first embodiment, since the four sets of the adjustable conveying units are provided with the respective elevation driving mechanisms 23, under the adjustment of the respective elevation driving mechanisms 23, it is possible to realize: in the operating state, the adjusting platforms 24 of the four groups of adjusting conveying parts can be adjusted to different heights, so that the adjusting platforms 24 of the adjusting conveying parts are prevented from colliding and interfering. Therefore, in the present embodiment, the four sets of adjusting and conveying units can independently receive the battery pieces from the battery piece input mechanism 10 and adjust the positions of the battery pieces without interfering with each other, move the battery pieces with the adjusted positions to the battery piece printing mechanism 40 for printing, and place the battery pieces to the battery piece output mechanism 60 after the printing is finished.

As will be appreciated by those skilled in the art, the higher the degree of matching of the angle of the cell in the horizontal direction to the angle of the screen assembly 43 of the cell printing mechanism 40 in the horizontal direction, the higher the print quality. Therefore, in the present embodiment, a DD motor is employed as the rotating electric machine. The DD motor has higher rotational positioning accuracy, and the DD motor is adopted to drive the bearing plate 243 to rotate, so that the accurate adjustment of the angle of the bearing plate 243 can be realized, the matching degree between the angle of the battery piece in the horizontal direction and the angle of the screen printing plate component 43 of the battery piece printing mechanism 40 in the horizontal direction is finally improved, and the battery piece printing effect is improved.

In the adjustment conveying part, as described in the first embodiment, the adjustment platform 24 is driven by the first translation driving mechanism 22 and the lifting driving mechanism 23 to translate and lift, so as to improve the stability of the adjustment platform 24 during translation and lifting, and prevent the battery pieces carried thereon from shaking and shifting.
