[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0020] Reference Figures 1 to 9 This invention provides a web-correcting mechanism 100 and a printing device incorporating the web-correcting mechanism 100. The printing device is used for printing on solar cells. The printing device includes a transport module 200, a printing stage 300, a positioning mechanism 400, the web-correcting mechanism 100, and a printing module 500. This printing device can print on single solar cells, half solar cells, or multiple single solar cells or multiple half solar cells.

[0021] The transmission module 200 is used to transmit the printing stage 300, which carries the battery cells to be printed. The positioning mechanism 400, the correction mechanism 100, and the printing module 500 are spaced apart along the transmission direction of the transmission module 200. The transmission module 200 first transmits the printing stage 300 to the area where the positioning mechanism 400 is located. The positioning mechanism 400 acquires image information of the battery cells to obtain precise position coordinate information of the battery cells. Then, the transmission module 200 transmits the printing stage 300 to the area where the correction mechanism 100 is located. The correction mechanism 100 adjusts and corrects the battery cells according to the position coordinate information acquired by the positioning mechanism 400, so that the position of the corrected battery cells matches the printing position on the printing module 500. Then, the transmission module 500 transmits the printing stage 300 to the area where the printing module 500 is located, and the printing module 500 prints on all the battery cells on the printing stage 300 simultaneously.

[0022] Compared to existing technologies that adjust the position and orientation of the printing module 500 to print on the printing stage 300, this application uses the correction mechanism 100 to adjust and correct the battery cells on the printing stage 300, ensuring that the placement and orientation of the battery cells correspond to the printing area on the printing module 500. This eliminates the need to adjust the position and orientation of the printing module 500. Consequently, multiple battery cells can be printed simultaneously, significantly improving printing efficiency.

[0023] The correction mechanism 100 includes an adjustment component and a suction cup component 40. The suction cup component 40 is used to pick up the battery cells on the printing stage 300. The adjustment component can drive the suction cup component 40 to move up and down in the vertical direction to pick up and place the cells. At the same time, it can adjust the position and posture of the suction cup component 40, thereby adjusting the position and posture of the battery cells on the suction cup component 40. Finally, the adjusted battery cells are placed back on the printing stage 300 according to a preset position, which corresponds to the printing position on the printing module 500.

[0024] When multiple battery cells to be printed are placed on the printing stage 300, the correction mechanism 100 can independently correct and adjust the position and orientation of the multiple battery cells; or, multiple correction mechanisms 100 can be arranged at intervals along the transmission direction of the transmission module 200 to correct and adjust the position of the multiple battery cells respectively, so that the printing module 500 can print all the battery cells on the printing stage 300 at the same time.

[0025] Specifically, the adjustment assembly includes a horizontal drive device 10, a plurality of lifting drive devices 20 connected to the horizontal drive device 10, and a rotary drive device 30 connected to the lifting drive device 20. The horizontal drive device 10 is used to drive the lifting drive device 20 to move in the horizontal direction, the lifting drive device 20 is used to drive the rotary drive device 30 to move in the vertical direction, and the suction cup assembly 40 is disposed on the rotary drive device 30. The rotary drive device 30 is used to drive the suction cup assembly 40 to rotate around its vertical axis.

[0026] The lifting drive device 20 drives the suction cup assembly 40 to move vertically, thereby picking up the battery cells on the printing stage 300 and repositioning the adjusted and corrected battery cells back onto the printing stage 300. The rotation drive device 30 drives the suction cup assembly 40 to rotate, thereby adjusting the posture of the battery cells. The horizontal drive device 10 drives the suction cup assembly 40 to move horizontally, thereby adjusting the position of the battery cells.

[0027] In this document, for ease of description, the transmission direction of the transmission module 200 is defined as the first direction, and the movement direction of the horizontal drive device 10 driving the lifting drive device 20 is defined as the second direction, which is perpendicular to the first direction.

[0028] It is understood that when the battery cell is located on the suction cup assembly 40, the position of the battery cell can be adjusted by moving the printing stage 300 along the first direction via the transmission module 200 and by moving the lifting drive device 20 along the second direction via the horizontal drive device 10; the posture of the battery cell can be adjusted by rotating the suction cup assembly 40 via the rotation drive device 30, so that the projection of the battery cell along the height direction on the printing stage 300 completely coincides with the preset position.

[0029] This application achieves the correction and adjustment of the position and orientation of the battery cells by moving the printing stage 300 in conjunction with the correction mechanism 100, thereby simplifying the structure of the correction mechanism 100 and reducing its manufacturing cost.

[0030] The horizontal drive device 10 employs a linear motor, and a drive plate 11 is connected to the mover of the horizontal drive device 10. The lifting drive device 20 is fixed to the drive plate 11. The movement of the drive plate 11 drives the lifting drive device 20 to move along the second direction, thereby correcting the position of the battery cells on the suction cup assembly 40 in the second direction. The linear motor drive is stable and has high movement accuracy, thus enabling efficient and precise correction of the battery cells' position in the second direction.

[0031] The lifting drive device 20 includes a support frame 21 fixed on the drive plate 11, a drive motor 22 disposed on the support frame 21, a drive screw 23 connected to the output end of the drive motor 22, and a drive block 24 threadedly connected to the drive screw 23. The drive block 24 is connected to the rotary drive device 30.

[0032] The drive screw 23 is vertically arranged. The drive motor 22 drives the drive screw 23 to rotate, thereby causing the drive block 24 to move along the drive screw 23, which in turn drives the rotary drive device 30 connected to the drive block 24 to move vertically, so as to pick up the battery cells on the printing stage 300 through the suction cup assembly 40 and place the adjusted and corrected battery cells back onto the printing stage 300.

[0033] Of course, in other embodiments, the lifting drive device 20 may also be a telescopic cylinder, a gear rack or a linear motor.

[0034] The rotary drive device 30 includes a first connecting plate 31 connected to the drive block 24 and a rotary drive component 32 mounted on the first connecting plate 31. The rotary drive component 32 is connected to the suction cup assembly 40 to drive the suction cup assembly 40 to rotate. The rotary drive component 32 moves vertically by the vertical movement of the first connecting plate 31. The rotation axis of the rotary drive component 32 is connected to the suction cup assembly 40, thereby driving the suction cup assembly 40 to rotate to achieve attitude adjustment of the battery cells on the suction cup assembly 40.

[0035] The drive plate 11 is provided with a guide rail 111, and the first connecting plate 31 is provided with a slider 311 that cooperates with the guide rail 111. The cooperation of the guide rail 111 and the slider 311 guides the rotation drive device 30 to move in the vertical direction, thereby improving the stability of the rotation drive device 30 during movement.

[0036] The drive plate 11 is provided with two sets of guide rails 111, and the support frame 21 is located on the support of the two sets of guide rails 111, thereby further improving the stability of the rotary drive device 30 during movement.

[0037] The first connecting plate 31 includes a first limiting plate 312 located at its top and a second limiting plate 313 located at its bottom. The rotary driving device 30 also includes a second connecting plate 33 slidably installed between the first limiting plate 312 and the second limiting plate 313. The rotary driving member 32 is connected to the second connecting plate 33.

[0038] The second connecting plate 33 can be slidably mounted on the first connecting plate 31 via the cooperation of a guide rail and a slider. The first limiting plate 312 and the second limiting plate 313 are used to limit the second connecting plate 33. When the second connecting plate 33 is in contact with the first limiting plate 312, the second connecting plate 33 is in its highest position; when the second connecting plate 33 is in contact with the second limiting plate 313, the second connecting plate 33 is in its lowest position. It can be understood that, under natural conditions, the second connecting plate 33 is in its lowest position due to gravity.

[0039] When the lifting drive device 20 drives the rotating drive device 30 to move downward so that the suction cup assembly 40 picks up the battery cell on the printing stage 300, if the lifting drive device 20 continues to drive the rotating drive device 30 to move downward after the suction cup assembly 40 contacts the battery cell, the suction cup assembly 40 may apply excessive pressure to the battery cell, causing the battery cell to break.

[0040] By setting the second connecting plate 33, this situation can be avoided. After the suction cup assembly 40 comes into contact with the battery cell, if the lifting drive device 20 continues to drive the rotating drive device 30 to move downward, the reaction force between the suction cup assembly 40 and the battery cell will cause the second connecting plate 33 to move upward, providing buffer space for the movement of the suction cup assembly 40, thereby preventing the suction cup assembly 40 from applying excessive pressure to the battery cell and causing damage to the battery cell.

[0041] The second connecting plate 33 is L-shaped and includes a first part 331 that is slidably installed between the first limiting plate 312 and the second limiting plate 313, and a second part 332 for installing the rotary drive component 32.

[0042] The rotary drive device 30 further includes an elastic element 34 connected between the first limiting plate 312 and the second connecting plate 33. Specifically, the elastic element 34 is connected between the first limiting plate 312 and the first portion 331. The elastic element 34 provides cushioning for the movement of the suction cup assembly 40, thereby preventing the suction cup assembly 40 from applying excessive pressure to the battery cell, which could cause damage to the battery cell.

[0043] In some embodiments, at least two lifting drive devices 20 are connected to the horizontal drive device 10, and the horizontal drive device 10 drives the two lifting drive devices 20 to move independently in the horizontal direction, that is, in the second direction.

[0044] When two lifting drive devices 20 are connected to the horizontal drive device 10, each lifting drive device 20 is connected to the rotary drive device 30 and the suction cup assembly 40. The two lifting drive devices 20 move independently along the second direction, thereby enabling simultaneous correction and adjustment of the two battery cells.

[0045] To enable the two horizontal drive devices 10 to drive the two lifting drive devices 20 to move independently along the second direction, the horizontal drive device 10 is provided with two movers, and the two lifting drive devices 20 are respectively mounted on the two movers through the drive plate 11. Driving force is generated by applying current to the two movers separately; or the stator of the horizontal drive device 10 is designed as two independent sections, with the two movers located on the two sections respectively. The corresponding mover is driven to move by energizing each section separately.

[0046] It should be noted that when the correction mechanism 100 simultaneously picks up two battery cells through the two suction cup assemblies 40 and corrects their alignment, the horizontal drive device 10 drives the two lifting drive devices 20 to move independently along the second direction, thereby allowing independent adjustment of the positions of the two battery cells along the second direction. The rotation drive device 30 can adjust the orientation of the two battery cells. Then, the printing stage 300 is moved along the first direction so that the projection of one battery cell along the height direction on the printing stage 300 completely coincides with the preset position. Then, the lifting drive device 20 corresponding to that battery cell is activated to place the battery cell on the printing stage 300. Then, the printing stage 300 is moved again along the first direction so that the projection of the other battery cell along the height direction on the printing stage 300 completely coincides with the preset position. Then, the lifting drive device 20 corresponding to that battery cell is activated to place the battery cell on the printing stage 300.

[0047] The suction cup assembly 40 includes a third connecting plate 41 connected to the rotary drive 32, a suction cup body 42 located below the third connecting plate 41, and a plurality of connecting posts 43 connecting the third connecting plate 41 and the suction cup body 42. The suction cup body 42 is used to pick up battery cells. By setting the connecting posts 43, the third connecting plate 41 and the suction cup body 42 are spaced apart, thereby facilitating the connection of vacuum tubes on the suction cup body 42.

[0048] In summary, compared to existing technologies that adjust the position and orientation of the printing module 500 to print on the printing stage 300, this application uses the correction mechanism 100 to adjust and correct the battery cells on the printing stage 300, ensuring that the placement and orientation of the battery cells correspond to the printing area on the printing module 500. This eliminates the need to adjust the position and orientation of the printing module 500. Consequently, multiple battery cells can be printed simultaneously, significantly improving printing efficiency.

[0049] Furthermore, the movement of the printing stage 300, in conjunction with the correction mechanism 100, completes the correction and adjustment of the position and orientation of the battery cells, thereby simplifying the structure of the correction mechanism 100 and reducing its manufacturing cost.

[0050] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0051] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
