[0068] like Figures 1-17 As shown, an embodiment of the present application provides a screen printing device 2000, comprising at least two screen printing devices 1000, namely a first screen printing device 2001 and a second screen printing device 2002, wherein the first screen printing device 2001 and the second screen printing device 2002 are spaced apart along the Y direction; the screen printing device 1000 comprises a loading and conveying mechanism, a first transporting mechanism, a processing mechanism, a second transporting mechanism and a unloading and conveying mechanism; the loading and conveying mechanism 100, the first transporting mechanism 300 and the processing mechanism 400 of the first screen printing device 2001 are correspondingly arranged in the Y direction with the loading and conveying mechanism 100 of the second screen printing device 2002; the second transporting mechanism 500 and the unloading and conveying mechanism 600 of the first screen printing device 2001 are correspondingly arranged in the Y direction with the first transporting mechanism 300, the processing mechanism 400, the second transporting mechanism 500 and the unloading and conveying mechanism 600 of the second screen printing device 2002.

[0069] like Figure 15-17 As shown, the screen printing apparatus 2000 includes two screen printing devices 1000, namely a first screen printing device 2001 and a second screen printing device 2002. The first screen printing device 2001 and the second screen printing device 2002 are spaced apart along the Y direction. Thus, the two screen printing devices 1000 can work simultaneously to improve production efficiency.

[0070] Specifically, the loading and conveying mechanism 100, the first transport mechanism 300 and the processing mechanism 400 of the first screen printing device 2001 are arranged correspondingly in the Y direction to the loading and conveying mechanism 100 of the second screen printing device 2002; specifically, the loading and conveying mechanism 100, the first transport mechanism 300 and the processing mechanism 400 of the first screen printing device 2001 are arranged at intervals along the X direction, and the loading and conveying mechanism 100 of the second screen printing device 2002 transfers materials in the X direction.

[0072] Therefore, the first screen printing device 2001 and the second screen printing device 2002 are staggered, that is, the processing mechanism 400 of the first screen printing device 2001 and the processing mechanism 400 of the second screen printing device 2002 are staggered in the Y direction, thereby reducing the occupied space of the processing mechanism 400 of the first screen printing device 2001 and the processing mechanism 400 of the second screen printing device 2002 in the Y direction, thereby making the structure of the screen printing equipment 2000 more compact and reducing the occupied space.

[0075] The screen printing device 1000 provided in this application can be used for screen printing on solar cells. In addition, the screen printing device 1000 can also be used in other fields. The embodiments of this application do not impose any specific restrictions on the specific use scenarios and working conditions of the screen printing device 1000.

[0076] like Figure 1 and Figure 2As shown, the loading conveying mechanism 100 and the first transporting mechanism 300 are used to transfer the materials to be processed to the processing mechanism 400; specifically, the loading conveying mechanism 100 transports the materials to be processed, and the first transporting mechanism 300 transfers the materials to be processed located on the loading conveying mechanism 100 to the processing mechanism 400 for processing; a correction station A is provided on the loading conveying mechanism 100, and a correction mechanism 200 is provided above the loading conveying mechanism 100 in the Z direction, and the correction mechanism 200 is located at the correction station A, and the correction mechanism 200 is used to adjust the position of the material to be processed at the loading conveying mechanism 100. The position of the material to be processed on the conveying mechanism 100 is arranged so that the first transport mechanism 300 can transfer the material on the loading conveying mechanism 100 to the processing mechanism 400; in this embodiment, the correction station A is arranged on the loading conveying mechanism 100, and the correction mechanism 200 is arranged above the loading conveying mechanism 100. It is no longer necessary to transfer the material to be processed to the correction station A for correction, thereby saving steps, improving production efficiency, and making the structure of the screen printing device 1000 more compact and saving space.

[0077] The unloading conveying mechanism 600 and the second transporting mechanism 500 are used to transfer the materials processed by the processing mechanism 400. Specifically, the unloading conveying mechanism 600 transports the processed materials, and the second transporting mechanism 500 transfers the processed materials on the processing mechanism 400 to the unloading conveying mechanism 600. The unloading conveying device is provided with an inspection station B. In the Z direction, a detection mechanism 700 is provided above the unloading conveying mechanism 600, and the detection mechanism 700 is located at the detection station B. The detection mechanism 700 is used to detect whether the processed materials on the unloading conveying mechanism 600 have defects. In this embodiment, the detection station B is provided on the unloading conveying mechanism 600, and the detection mechanism 700 is provided above the unloading conveying mechanism. It is no longer necessary to transfer the processed materials to the detection station B for inspection, thereby saving steps, improving production efficiency, and making the structure of the screen printing device 1000 more compact, saving space.

[0078] In an optional embodiment, the processing mechanism 400 includes a loading station C, a printing station D, a printing platform 401 and a printing component 402; the loading station C is located downstream of the first conveying mechanism 300; the printing station D is located downstream of the loading station C; the printing platform 401 is arranged between the loading station C and the printing station D, and the printing platform 401 can move between the loading station C and the printing station D, and the first conveying mechanism 300 can transfer the material to be processed located at the correction station A to the printing platform 401 located at the loading station C; the printing component 402 is arranged at the printing station D, and the printing component 402 can process the material to be processed on the printing platform 401 located at the printing station D.

[0079] like Figure 1 and Figure 2 As shown, the processing mechanism 400 includes a printing platform 401 and a printing component 402, and is also provided with a loading station C and a printing station D.

[0080] Among them, the loading station C is located downstream of the first conveying mechanism 300, the printing station D is located downstream of the loading station C, the second conveying mechanism 500 is located downstream of the printing station D, and the printing platform 401 is arranged between the loading station C and the printing station D. The printing platform 401 can move between the loading station C and the printing station D. When the printing platform 401 is located at the loading station C, the first conveying mechanism 300 transfers the material to be processed at the correction station A to the printing platform 401, and the printing platform 401 moves to the printing station D. In the Z direction, the printing component 402 is located above the printing station D. The printing component 402 can process the material to be processed on the printing platform 401 at the printing station D, thereby obtaining processed materials; the second conveying mechanism 500 can transfer the processed materials at the printing station D to the unloading conveying mechanism 600, thereby realizing unloading.

[0081] like Figure 1 and Figure 2 As shown, in an optional embodiment, the processing mechanism 400 also includes a detection component 403, which is arranged at the loading station C and located above the loading station C, and the detection component 403 can detect the position of the material to be processed on the printing platform 401 located at the loading station C; the printing component 402 includes a printing head and a correction component, and the printing head is connected to the correction component, and the correction component can adjust the position of the printing head according to the detection position of the detection component 403.

[0082] Before the printing platform 401 moves from the loading station C to the printing station D, the detection component 403 detects the position of the material to be processed on the printing platform 401. During the process of the printing platform 401 moving from the loading station C to the printing station D, the correction component adjusts the position of the print head according to the detection data of the detection component 403, so that the print head can process the material to be processed on the printing platform 401 at the printing station D, thereby improving its processing accuracy. In addition, the correction component adjusts the position of the print head during the movement of the printing platform 401, thereby also improving the working efficiency of the screen printing device 1000.

[0083] Preferably, the screen printing device 1000 also includes a control system, the detection component 403 is communicatively connected to the control system, and the correction component is communicatively connected to the control system. The detection component 403 transmits the detection data to the control system, and the control system controls the correction component to work according to the detection transmission. The correction component adjusts the position of the printing head so that the position of the printing head corresponds to the position of the material to be processed on the printing platform 401, so that the printing head and the material to be processed on the printing platform 401 can be processed. Through the control system, the screen printing device 1000 is automated, thereby improving processing accuracy and processing efficiency.

[0084] like Figure 3-Figure 6 As shown, the printing head includes a mounting bracket 1 , a first driving mechanism 2 , a second driving mechanism 3 , a first scraper 51 and a second scraper 52 .

[0085] The first drive mechanism 2 and the second drive mechanism 3 are spaced apart on the mounting bracket 1 along the X direction, so that the first drive mechanism 2, the second drive mechanism 3 and the mounting bracket 1 are modularized for easy maintenance.

[0086] The first driving mechanism 2 includes a first connecting plate 24 , which is detachably connected to the first scraper 51 , thereby facilitating replacement of the first scraper 51 and adjusting the angle of the first scraper 51 as needed.

[0087] The second driving mechanism 3 includes a second connecting plate 34 , which is detachably connected to the second scraper 52 , thereby facilitating replacement of the second scraper 52 and adjusting the angle of the second scraper 52 as needed.

[0088] Therefore, the printing head provided in the embodiment of the present application has a simple structure and is easy to inspect and maintain.

[0089] The first scraper 51 may be an ink return blade, and the second scraper 52 may be a scraper; or the first scraper 51 may be a scraper, and the second scraper 52 may be an ink return blade; or both the first scraper 51 and the second scraper 52 may be scrapers.

[0090] like Figure 3-Figure 5 As shown, an accommodating space 15 is formed in the mounting bracket 1. Specifically, the mounting bracket 1 includes a first mounting plate 11, a second mounting plate 12, a third mounting plate 13 and a fourth mounting plate 14. The first mounting plate 11 and the third mounting plate 13 are spaced apart along the Z direction, and the second mounting plate 12 and the fourth mounting plate 14 are spaced apart along the X direction. The second mounting plate 12 connects the first mounting plate 11 and the third mounting plate 13, and the fourth mounting plate 14 connects the first mounting plate 11 and the third mounting plate 13. Therefore, the first mounting plate 11, the second mounting plate 12, the third mounting plate 13 and the fourth mounting plate 14 enclose the accommodating space 15.

[0091] The first drive mechanism 2 also includes a first motor 21 and a third drive assembly. The first motor 21 is mounted on the first mounting plate 11, and the third drive assembly is located within the accommodating space 15. A first through-hole is defined in the first mounting plate 11, through which the drive end of the first motor 21 connects to the third drive assembly. A second through-hole is defined in the third mounting plate 13, through which the first connecting plate 24 connects to the third drive assembly. The first motor 21 drives the third drive assembly to move the first connecting plate 24 in the Z direction, thereby moving the first scraper 51 in the Z direction.

[0092] The second drive mechanism 3 also includes a second motor 31 and a fourth drive assembly. The second motor 31 is mounted on the first mounting plate 11, spaced apart from the first motor 21 along the X-direction. The fourth drive assembly is located within the accommodating space 15, spaced apart from the third drive assembly along the X-direction. A third through-hole is defined on the first mounting plate 11, through which the drive end of the second motor 31 is connected to the fourth drive assembly. A fourth through-hole is also defined on the third mounting plate 13, through which the second connecting plate 34 is connected to the fourth drive assembly. The second motor 31 drives the fourth drive assembly to move the second connecting plate 34 along the Z-direction, thereby moving the second scraper 52 along the Z-direction.

[0093] like Figure 3-Figure 5As shown, the third driving assembly includes a first lead screw 22, a first guide rail 23 and a first nut seat 25. The first lead screw 22 is connected to the driving end of the first motor 21. The length direction of the first lead screw 22 is the same as the Z direction. The first motor 21 drives the first lead screw 22 to rotate, and the first lead screw 22 rotates around the Z direction. The first nut seat 25 is sleeved on the first lead screw 22 and is rotationally connected to the first lead screw 22. Therefore, when the first lead screw 22 rotates around the Z direction, the first nut seat 25 can move relative to the length direction of the first lead screw 22, that is, the first nut seat 25 can move along the Z direction. The first connecting plate 24 is connected to the first nut seat 25. When the first lead screw 22 rotates around the Z direction, the first nut seat 25 can move relative to the length direction of the first lead screw 22. That is, the first nut seat 25 can move along the Z direction. When the base 25 moves along the Z direction, its first connecting plate 24 will also move accordingly; the first guide rail 23 is set on the mounting bracket 1, and the length direction of the first guide rail 23 is the same as the Z direction. The first connecting plate 24 is slidably connected to the first guide rail 23 through the first slider. Therefore, when the first connecting plate 24 moves along the Z direction, the first slider will move along the first guide rail 23 in the Z direction. The first guide rail 23 can provide a guiding effect for the first connecting plate 24 to move along the Z direction to avoid the first connecting plate 24 from deflecting, and further avoid the first scraper 51 from deflecting.

[0094] like Figure 3-Figure 5 As shown, the fourth driving assembly includes a second lead screw 32, a second guide rail 33, a second nut seat 35 and a driving member 36. Among them, the second lead screw 32 is connected to the driving end of the second motor 31, and the length direction of the second lead screw 32 is the same as the Z direction. The second motor 31 drives the second lead screw 32 to rotate, and the second lead screw 32 rotates around the Z direction; the second nut seat 35 is sleeved on the second lead screw 32 and is rotationally connected to the second lead screw 32, so when the second lead screw 32 rotates around the Z direction, the second nut seat 35 can move relative to the length direction of the second lead screw 32, that is, the second nut seat 35 can move along the Z direction; the driving member 36 is set on the second nut seat 35, and the driving member 36 can move along the Z direction with the second nut seat 35. The driving end of the driving member 36 is connected to the second connecting plate 34, so when the second When the nut seat 35 moves along the Z direction, the second connecting plate 34 will also move accordingly, and the driving member 36 can independently drive the second connecting plate 34 to move along the Z direction to fine-tune the second scraper 52 in the Z direction; the second guide rail 33 is arranged on the mounting bracket 1, and the length direction of the second guide rail 33 is the same as the Z direction. The second connecting plate 34 is slidingly connected to the second guide rail 33 through the second slider.

[0106] In an optional embodiment, the inspection station B is located on the side of the unloading conveying mechanism 600 close to the second transporting mechanism 500, so that the inspection mechanism 700 can first inspect the processed materials and then convey them. If the processed materials are defective products, they can also be transferred to the defective product conveying line.

[0107] The loading conveying mechanism 100, the first transport mechanism 300, the printing platform 401, the second transport mechanism 500 and the unloading conveying mechanism 600 are arranged adjacent to each other along the X direction. The first transport mechanism 300 and the second transport mechanism 500 have the same structure. The loading conveying mechanism and the unloading conveying mechanism have the same structure.

[0108] Among them, the loading conveying mechanism 100 includes a first conveyor belt 101 and a second conveyor belt 102, and the first conveyor belt 101 and the second conveyor belt 102 are arranged at intervals along the Y direction. A certain space is left between the first conveyor belt 101 and the second conveyor belt 102. The transfer component of the first handling mechanism 300 can lift the materials located on the first conveyor belt 101 and the second conveyor belt 102 in the Z direction between the first conveyor belt 101 and the second conveyor belt 102.

[0109] like Figure 7-14 As shown, the printing platform 401 includes a carrying surface 611 for carrying battery cells. The carrying surface 611 is provided with at least two first grooves 612, which are spaced apart along the Y direction, and the depth direction of the first grooves 612 is the Z direction. The first transport mechanism 300 includes a transfer assembly 71, which includes at least two inserts 711, which are used to carry battery cells, and are spaced apart along the Y direction. The first transport mechanism 300 transfers the battery cells to the printing platform 401 so that one insert 711 is inserted into one first groove 612 and the other insert 711 is inserted into the other first groove 612, thereby transferring the battery cells to the printing platform 401 and ensuring the battery cells are positioned on the carrying surface 611 of the printing platform 401, thereby facilitating subsequent processing of the battery cells.

[0113] When the first transport mechanism 300 transfers the battery cell to be processed to the printing platform 401, the second drive assembly 73 drives the first drive assembly 72 to move upward along the Z direction, and the first drive assembly 72 drives the transfer assembly 71 to move along the X direction, so that the ruler 711 is located above the printing platform 401. The second drive assembly 73 then drives the first drive assembly 72 to move downward along the Z direction, so that the ruler 711 is located in the first groove 612. The battery cell to be processed located on the ruler 711 will fall on the supporting surface 611 of the printing platform 401. The first drive assembly 72 drives the transfer assembly 71 to move along the X direction away from the printing platform 401, so that the ruler 711 of the transfer assembly 71 is removed from the first groove 612, and the loading is completed.

[0114] When the second transport mechanism 500 transfers the processed battery cell from the printing platform 401, the first drive assembly 72 drives the transfer assembly 71 to move along the X direction so that the insert ruler 711 is inserted into the first groove 612 of the printing platform 401. The second drive assembly 73 drives the first drive assembly 72 to move along the Z direction away from the printing platform 401 to lift the battery cell located on the carrying surface 611. The first drive assembly 72 drives the transfer assembly 71 to move along the X direction away from the printing platform 401, thereby removing the processed battery cell.

[0115] In an optional embodiment, the first drive assembly 72 can be a hydraulic cylinder or an electric cylinder; preferably, as Figure 9As shown, the first driving component 72 includes a third motor 721, a driving wheel 722, a driven wheel 723 and a transmission belt 724. The driving wheel 722 and the driven wheel 723 are spaced apart along the X direction. The output end of the third motor 721 is connected to the driving wheel 722. The transmission belt 724 is sleeved on the driving wheel 722 and the driven wheel 723. The transfer component 71 is connected to the transmission belt 724. The third motor 721 drives the driving wheel 722 to rotate, thereby driving the transmission belt 724 to rotate, thereby driving the transfer component 71 to move along the X direction. The structure is simple and the cost is low.

[0116] In an optional embodiment, the second drive assembly 73 may adopt a hydraulic cylinder, an electric cylinder, or a motor and a screw.

The bearing end surface 7113 is used to support battery cells, and the first adsorption holes 7112 can adsorb the battery cells, preventing them from falling off the insert 711 as the insert 711 moves.

[0118] In an optional embodiment, a wear-resistant tape is provided on the bearing end surface 7113. When the battery cell is located on the bearing end surface 7113, the wear-resistant tape can be used to increase the wear resistance of the surface in contact with the battery cell.

[0119] In the prior art, the driving mechanism for the printing platform 401 is set on the side of the printing platform 401, so that the printing platform 401 is suspended and the bottom 64 of the printing platform 401 is unsupported, which makes the flatness of the printing platform 401 low.

[0120] like Figure 13 As shown, the bottom 64 of the printing platform 401 is connected to the driving end of the linear motor 8, so that the linear motor 8 can provide a certain support for the printing platform 401, thereby improving the flatness of the printing platform 401 and improving the processing quality of the battery cell.

[0121] The bottom 64 of the printing platform 401 refers to the end opposite to the supporting surface 611 in the Z direction.

[0122] In an optional embodiment, a second groove 19 is formed on a side of the printing platform 401 close to the linear motor 8 , and a carrying plate 9 is provided in the second groove 19 . The carrying plate 9 is used to receive and place the crushed material.

[0123] like Figure 13 As shown, a second groove 19 is provided on the side of the printing platform 401 close to the linear motor 8, that is, a second groove 19 is provided on the bottom 64 of the printing platform 401, and the printing platform 401 is located above the linear motor 8 in the Z direction, and the depth direction of the second groove 19 is the same as the Z direction; a carrying plate 9 is provided in the second groove 19, and when the battery cell located on the carrying surface 611 is broken, the carrying plate 9 will catch the fragments of the battery cell, thereby preventing the fragments of the battery cell from falling into the linear motor 8, thereby avoiding damage to the linear motor 8.

[0124] In an optional embodiment, an adjustment component 65 is provided on one side of the printing platform 401 connected to the linear motor 8 , and the adjustment component 65 is used to adjust the flatness of the printing platform 401 .

[0125] like Figure 11 As shown, the printing platform 401 is provided with a plurality of third connecting portions 66, which are used to connect to the driving end of the linear motor 8. At the third connecting portions 66, the linear motor 8 is connected to the printing platform 401 via bolts 67. The adjustment assembly 65 is provided at the third connecting portion 66. The adjustment assembly 65 can adjust the flatness of the printing platform 401 to prevent the battery cells from being skewed, thereby improving the processing quality of the battery cells.

[0126] Preferably, if Figure 14 As shown, in the Y direction, third connecting parts 66 are provided on both sides of the printing platform 401, and three third connecting parts 66 are provided on each side along the X direction. Each third connecting part 66 is provided with a bolt 67 and two adjustment components 65. The bolt 67 is used to connect the printing platform 401 and the driving end of the linear motor 8, and the adjustment component 65 is used to adjust the flatness of the printing platform 401.

[0127] Among them, the adjustment component 65 can use a top screw, which passes through the third connecting part 66 and contacts the driving end of the linear motor 8. By adjusting the size of the top screw screwed into the third connecting part 66, the gap between the printing platform 401 and the driving end of the linear motor 8 can be adjusted to adjust the flatness of the printing platform 401.

[0128] like Figure 11-14 As shown, the printing platform 401 further includes a body and a paper changing frame 61 , wherein the body is connected to the driving end of the linear motor 8 , and the paper changing frame 61 is arranged on the body.

[0129] Further explanation, such as Figure 11 As shown, a first magnet 68 is provided at one end of the main body away from the linear motor 8, and a second magnet 613 is provided on the paper changing frame 61. The paper changing frame 61 is provided on the main body, and the first magnet 68 and the second magnet 613 attract each other, thereby fixing the paper changing frame 61 on the main body, and the paper changing frame 61 and the main body are detachably connected, which is convenient for replacing the paper changing frame 61 and also for replacing paper in the paper changing frame 61.

[0130] In an alternative embodiment, Figure 11 As shown, the bearing surface 611 is located at an end of the paper-changing frame 61 away from the body, and the first groove 612 is opened in the paper-changing frame 61 .

[0131] like Figure 11 As shown, the body includes a first mounting portion 62 and a second mounting portion 63. The paper-changing frame 61 is mounted on the first mounting portion 62, that is, the first magnet 68 is mounted on the first mounting portion 62, and the second magnet 613 of the paper-changing frame 61 attracts the first magnet 68 on the first mounting portion 62; the second mounting portion 63 is connected to the drive end of the linear motor 8.

The first mounting portion 62 is connected to the second mounting portion 63 to seal the second ventilation channel 631. The second adsorption hole 621 is connected to the second ventilation channel 631, and the paper changing frame 61 is located on the first mounting portion 62. Therefore, the second adsorption hole 621 can adsorb the battery cells located on the paper changing frame 61, thereby preventing the battery cells from being transferred on the carrying surface 611.

[0133] To further illustrate, the second ventilation channel 631 is opened in the second mounting portion 63 along a preset direction. For example, with the airflow running in the middle of the second ventilation channel 631, the second ventilation channel 631 can be annular, triangular, star-shaped or irregular in shape. The first mounting portion 62 seals the second mounting portion 63, so that the second ventilation channel 631 has better sealing performance and the adsorption force of its second adsorption hole 621 is relatively uniform and high.

[0134] The first mounting portion 62 may be in a plate shape or a block shape, and the second mounting portion 63 may be in a plate shape or a block shape.
