[0053] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0054] First, it should be noted that the X, Y, and Z directions mentioned in the embodiments of this application are referred to in the appendix. Figure 1 , Figure 4 and Figure 8 The marked directions. Among them, the axes in the X direction, Y direction, and Z direction intersect each other.

[0055] like Figures 1-10 As shown, according to a first aspect of the embodiments of this application, a printing screen is provided, including a screen structure 100, the screen structure 100 including a screen frame 1 and an ink printing portion 2; the ink printing portion 2 is disposed on the screen frame 1, the ink printing portion 2 includes a protrusion 21, at least a portion of the protrusion 21 protruding from the bottom of the screen frame 1, and the ink printing portion 2 has a mesh hole 22 penetrating the ink printing portion 2 at the protrusion 21.

[0056] The printing screen of this application is suitable for a printing system. When the printing system applies adhesive to the solder ribbon located on the battery cell, the solder ribbon is placed on the battery cell and a pressure screen is placed on the solder ribbon.

[0057] In the existing technology, when using a thick pressure screen, the thick pressure screen has a certain thickness. When the printing screen is close to the pressure screen, due to the thickness of the thick pressure screen, there is still a large gap between the printing screen and the solder ribbon, making it impossible to accurately apply adhesive.

[0058] like Figures 1-5 As shown, the printing screen includes a frame 1 and an ink printing section 2.

[0059] To further explain, the interior of the frame 1 has an installation space 13, the printing part 2 is located in the installation space 13 and is connected to the frame 1. The printing part 2 includes a protrusion 21, at least a portion of which protrudes from the bottom of the frame 1. The printing part 2 has a mesh hole 22 that passes through the protrusion 21, and the axis of the mesh hole 22 is the same as the axis in the Z direction.

[0060] When the printing screen is applied to the printing system, the protrusion 21 will extend into the gap of the screen to press the solder ribbon or leave a certain gap between it and the solder ribbon. The dispensing component of the printing system will inject glue into the printing section 2. The glue will be printed onto the solder ribbon and the cell through the mesh 22 to form glue dots on the cell to fix the solder ribbon.

[0061] In the Z direction, the bottom of the frame 1 is the end facing downwards.

[0062] In this embodiment, since at least a portion of the protrusion 21 protrudes from the bottom of the frame 1, the portion of the protrusion 21 protruding from the bottom of the frame 1 can easily extend into the pressure screen, thereby allowing the printing part 2 to abut against the solder ribbon or reducing the distance between the printing part 2 and the solder ribbon. When dispensing adhesive through the mesh 22, the adhesive can be accurately printed onto the solder ribbon and the battery cell through the mesh 22.

[0063] In one optional embodiment, the printing part 2 has a groove 26 at the end away from the protrusion 21, and one end of the mesh 22 is located in the groove 26; specifically, the printing part 2 has a groove 26 at the end away from the protrusion 21, the depth direction of the groove 26 is the same as the Z direction, one end of the mesh 22 is located in the groove 26, and the other end of the mesh 22 is located on the protrusion 21; in this embodiment, the interior of the groove 26 is used to contain glue, and the groove 26 can prevent the glue from flowing to other areas.

[0064] like Figures 1-3 As shown, in another optional embodiment, the end of the printing part 2 away from the bottom of the screen frame 1 is a plane. This embodiment is applicable to printing screens that include a printing part 2, which has a plurality of protrusions 21. The printing part 2 has a plurality of mesh holes 22, the positions of which correspond to the positions of the protrusions 21. One end of the mesh hole 22 is located on the plane, and the other end of the mesh hole 22 is located on the corresponding protrusion 21.

[0065] like Figure 2 , Figure 6 and 7 As shown, in an optional embodiment, the printing part 2 includes a body 23, a first mounting part 24, and a first elastic member 27. One end of the first mounting part 24 is connected to the body 23. Specifically, the groove 26 is located on the body 23, and the protrusion 21 is located on the body 23, both of which are part of the body 23. The body 23 includes a first end and a second end, which are arranged along the Y direction. One end of the first mounting part 24 is connected to the first end.

[0066] Further explanation: the wire frame 1 is provided with a first mounting hole 11, and the other end of the first mounting part 24 is disposed in the first mounting hole 11. There is a gap between the first mounting part 24 and the inner wall of the first mounting hole 11. The first elastic element 27 is located between the first mounting part 24 and the upper wall of the first mounting hole 11. Specifically, the wire frame 1 is provided with a first mounting hole 11, and the axis of the first mounting hole 11 is parallel to the axis in the Y direction (this parallelism means basically parallel, and there can be a certain error). One end of the first mounting part 24 is disposed in the first mounting hole 11. In the Z direction, the gap between the first mounting part 24 and the inner wall of the first mounting hole 11 is formed. The gap allows the first mounting part 24 to move a certain amount in the Z direction inside the first mounting hole 11. The first elastic member 27 is disposed between the first mounting part 24 and the upper wall of the first mounting hole 11. The upper wall of the first mounting hole 11 is part of the inner wall of the first mounting hole 11. The upper wall of the first mounting hole 11 refers to the side facing downward in the Z direction. The direction of the elastic force of the first elastic member 27 is in the Z direction. In this embodiment, when the protrusion 21 extends into the through groove and abuts against the solder strip, the height of the printing part 2 can be adjusted by compressing the first elastic member 27, and a buffering effect can be provided when the protrusion 21 abuts against the solder strip.

[0067] Preferably, the first mounting part 24 has a first receiving hole, the axis of the first receiving hole is in the Z direction, and one end of the first elastic member 27 is located in the first receiving hole to facilitate the installation of the first elastic member 27.

[0068] In an optional embodiment, a first through hole 18 is provided at the bottom of the mesh frame 1, and the first through hole 18 communicates with the first mounting hole 11. Specifically, the axis of the first through hole 18 intersects the axis of the first mounting hole 11, one end of the first through hole 18 is located at the bottom of the mesh frame 1, and the other end of the first through hole 18 communicates with the first mounting hole 11. That is, the other end of the first through hole 18 is located on the lower wall of the first mounting hole 11, and the lower wall of the first mounting hole 11 is part of the inner wall of the first mounting hole 11. The lower wall of the first mounting hole 11 refers to the side facing upward in the Z direction.

[0069] like Figure 2 , Figure 4 and Figure 7 As shown, the printing part 2 further includes a first limiting part 28, which passes through the first through hole 18 and is connected to the first mounting part 24. The first elastic member 27 is located at the end of the first mounting part 24 away from the first through hole 18. Specifically, the first limiting part 28 passes through the first through hole 18 at the bottom of the frame 1 and is connected to the first mounting part 24. The end of the first limiting part 28 away from the first mounting part 24 is located outside the first through hole 18, and the first elastic member 27 is located at the end of the first mounting part 24 away from the first through hole 18. When the protrusion 21 extends into the through groove, the first limiting part 28 will contact other components of the printing station of the screen pressing or printing system. In this embodiment, the first limiting part 28 abuts against other components of the screen pressing or printing system. The first elastic member 27 can be compressed by the first limiting part 28 to adjust the height of the printing part 2. Therefore, the force of compressing the first elastic member 27 is transferred to the first limiting part 28, thereby preventing the protrusion 21 from exerting force on the solder strip and thus preventing damage to the battery cell. Furthermore, by replacing the first limiting part 28 with different lengths, the contact between the protrusion 21 and the solder strip can be adjusted.

[0070] like Figure 2 and Figure 5 As shown, in an optional embodiment, the wire mesh frame 1 includes a frame 15 and a first mounting member 16. The frame 15 has a first mounting groove 151, and the first mounting member 16 is disposed on the frame 15 and covers the first mounting groove 151. The first mounting groove 151 and the first mounting member 16 form the first mounting hole 11. Specifically, the wire mesh frame 1 includes a frame 15, and the frame 15 is formed by a first mounting rod 153, a second mounting rod 154, a third mounting rod 155, and a fourth mounting rod 156 connected in sequence to form an installation space 13. The first mounting rod 153 and... The third mounting rod 155 is arranged opposite to each other, and the second mounting rod 154 and the fourth mounting rod 156 are arranged opposite to each other; a first mounting groove 151 is provided on the frame 15, and the first mounting groove 151 can be opened on the first mounting rod 153. The first mounting groove 151 has an opening facing upward in the Z direction; the first mounting part 24 is installed into the first mounting groove 151 at the opening, and the first mounting member 16 is provided on the frame 15 and covers the opening of the first mounting groove 151, so that the first mounting part 24 is located in the first mounting hole 11; in this embodiment, it is more convenient to install the printing part 2 and the screen frame 1.

[0071] In an optional embodiment, the printing part 2 further includes a second mounting part 25 and a second elastic member (not shown in the figure, but can be referenced). Figure 7(In the installation of the first elastic element 27), the second mounting part 25 and the first mounting part 24 are respectively located at both ends of the body 23, and one end of the second mounting part 25 is connected to the body 23; that is, one end of the second mounting part 25 is connected to the second end of the body 23.

[0072] like Figure 3 As shown, further explained, the wire frame 1 is provided with a second mounting hole 12, and the other end of the second mounting part 25 is provided in the second mounting hole 12. There is a gap between the second mounting part 25 and the inner wall of the second mounting hole 12. The second elastic member is located between the second mounting part 25 and the upper wall of the second mounting hole 12. Specifically, the wire frame 1 is provided with a second mounting hole 12, the axis of the second mounting hole 12 is parallel to the axis in the Y direction (this parallelism means basically parallel, and there can be a certain error). The second mounting hole 12 is arranged opposite to the first mounting hole 11. One end of the second mounting part 25 is provided in the second mounting hole 12. In the Z direction, a gap is formed between the second mounting part 25 and the inner wall of the second mounting hole 12, which allows the wire frame 1 to be positioned so that the second mounting part 25 can be positioned in the second mounting hole 12. The second mounting portion 25 is movable in the Z direction inside the second mounting hole 12. The second elastic member is disposed between the second mounting portion 25 and the upper wall of the second mounting hole 12. The upper wall of the second mounting hole 12 is part of the inner wall of the second mounting hole 12. The upper wall of the second mounting hole 12 refers to the side facing downward in the Z direction. The direction of the elastic force of the second elastic member is the Z direction. In this embodiment, when the protrusion 21 extends into the through groove and abuts against the solder strip, the height of the printing portion 2 can be adjusted by compressing the second elastic member, and a buffering effect can be provided when the protrusion 21 abuts against the solder strip. Furthermore, both ends of the body 23 can be adjusted by the first elastic member 27 and the second elastic member to avoid the body 23 from tilting.

[0073] Preferably, the second mounting part 25 has a second receiving hole, the axis of the second receiving hole is in the Z direction, and one end of the second elastic member is located in the second receiving hole to facilitate the installation of the second elastic member.

[0074] In an optional embodiment, a second through hole (not shown in the figure, but refer to the first through hole 18) is provided at the bottom of the mesh frame 1. The second through hole communicates with the second mounting hole 12, and the first through hole 18 and the second through hole are spaced apart. The axis of the second through hole intersects the axis of the second mounting hole 12. One end of the second through hole is located at the bottom of the mesh frame 1, and the other end of the second through hole communicates with the second mounting hole 12. That is, the other end of the second through hole is located on the lower wall of the second mounting hole 12. The lower wall of the second mounting hole 12 is part of the inner wall of the second mounting hole 12. The lower wall of the second mounting hole 12 refers to the side facing upward in the Z direction.

[0075] like Figure 4As shown, further illustrating, the printing part 2 also includes a second limiting part 29, which passes through the second through hole and connects to the second mounting part 25. The second elastic member is located at the end of the second mounting part 25 away from the second through hole. Specifically, the second limiting part 29 passes through the second through hole at the bottom of the frame 1 and connects to the second mounting part 25. The end of the second limiting part 29 away from the second mounting part 25 is located outside the second through hole, and the second elastic member is located at the end of the second mounting part 25 away from the second through hole. When the protrusion 21 extends... When inserted into the through groove, the second limiting part 29 will contact other components of the printing station of the screen pressing or printing system. In this embodiment, the second limiting part 29 abuts against other components of the screen pressing or printing system. The second elastic member can be compressed by the second limiting part 29 to adjust the height of the printing part 2. Therefore, the force of compressing the second elastic member is transferred to the second limiting part 29, thereby preventing the protrusion 21 from exerting force on the solder strip and thus preventing damage to the battery cell. Furthermore, by replacing the second limiting part 29 with different lengths, the contact or non-contact between the protrusion 21 and the solder strip can be adjusted.

[0076] In an optional embodiment, the frame 1 includes a frame 15 and a second mounting member 17. The frame 15 has a second mounting groove 152, and the second mounting member 17 is disposed on the frame 15 and covers the second mounting groove 152. The second mounting groove 152 and the second mounting member 17 form the first mounting hole 11. Specifically, the frame 15 has a second mounting groove 152, which can be formed on a third mounting rod 155. The second mounting groove 152 has an opening facing upward in the Z direction. The second mounting part 25 is installed into the second mounting groove 152 at the opening. The second mounting member 17 is disposed on the frame 15 and covers the opening of the second mounting groove 152, so that the second mounting part 25 is located in the second mounting hole 12. In this embodiment, it is more convenient to install the printing part 2 and the frame 1.

[0077] like Figure 1 and Figure 4 As shown, in an optional embodiment, the screen structure 100 further includes a first driving component 3, the driving end of the first driving component 3 being connected to the screen frame 1; specifically, the first driving component 3 can drive the screen frame 1 to move along the Z direction, thereby driving the printing part 2 to move along the Z direction; in this embodiment, the first driving component 3 is used to drive the printing part 2 to move closer to or further away from the printing station.

[0078] In one alternative embodiment, the printing screen includes an ink printing section 2 disposed within the screen frame 1. The ink printing section 2 has a plurality of protrusions 21 spaced apart. The protrusions 21 protrude from the bottom of the screen frame 1, and one protrusion 21 extends into a through groove of the screen pressing plate.

[0079] In another alternative embodiment, the printing screen includes a plurality of printing ink sections 2, which are spaced apart. Specifically, since the screen is provided with a plurality of through slots, one printing ink section 2 extends into one through slot. In this embodiment, the plurality of printing ink sections 2 are individually arranged on the screen frame 1, and each printing ink section 2 can be installed and adjusted individually, which provides high flexibility.

[0080] Furthermore, in the above embodiment, the frame 1 is provided with a plurality of first mounting holes 11 and a plurality of second mounting holes 12, and a printing part 2 is installed in the corresponding first mounting hole 11 and second mounting hole 12.

[0081] like Figures 8-10 As shown, in an optional embodiment, a cleaning structure 200 is further included. The cleaning structure 200 includes a second driving component 5 and a cleaning component 4. The cleaning component 4 is disposed at the driving end of the second driving component 5 and is disposed adjacent to the screen structure 100. Specifically, the cleaning component 4 is disposed adjacent to the screen structure 100, and the second driving component 5 can drive the cleaning component 4 to move along the X direction to move the cleaning component 4 below the screen structure 100, and drive the cleaning component 4 to be below the screen structure 100 along the X direction. Movement; During multiple printing cycles, excess glue accumulates on the bottom of the screen structure 100. The second drive assembly 5 drives the cleaning assembly 4 to move along the X direction. During this movement, the cleaning assembly 4 wipes the bottom of the screen structure 100, thus cleaning the bottom of the screen structure 100 after multiple printing cycles to ensure printing quality. After cleaning is complete, the second drive assembly 5 drives the cleaning assembly 4 to move out of the screen structure 100, so as not to affect the normal operation of the screen structure 100.

[0082] like Figure 8 and Figure 9As shown, in an optional embodiment, the second driving component 5 includes a driving member 51 and a mounting bracket 52. The mounting bracket 52 is disposed at the driving end of the driving member 51, and the cleaning component 4 is rotatably connected to the mounting bracket 52. Specifically, the mounting bracket 52 is disposed at the driving end of the driving member 51, and the cleaning component 4 is rotatably connected to the mounting bracket 52. The driving member 51 can drive the mounting bracket 52 and the cleaning component 4 to move in the X direction. When the cleaning component 4 cleans the screen structure 100, the driving member 51 drives the mounting bracket 52 and the cleaning component 4 to move in the X direction. The cleaning component 4 contacts the screen structure 100, and the cleaning component 4 can rotate around its own axis through friction, thereby improving the uniformity of the cleaning surface of the cleaning component 4, thus improving the service life and cleaning effect of the cleaning component 4.

[0083] The axis of cleaning component 4 is parallel to the axis in the Y direction.

[0084] like Figure 8 and Figure 9 As shown, in an optional embodiment, the cleaning component 4 includes a cleaning roller 41 and a mounting shaft 42, the mounting shaft 42 being disposed at one end of the cleaning roller 41; specifically, the cleaning roller 41 is used to clean the screen structure 100, and the mounting shaft 42 is disposed at one end of the cleaning roller 41, the axis of the mounting shaft 42 coinciding with the axis of the cleaning roller 41.

[0085] To further explain, the mounting frame 52 includes a first mounting plate 521 and a second mounting plate 522. The first mounting plate 521 and the second mounting plate 522 are spaced apart along the axial direction of the mounting shaft 42. The mounting shaft 42 is rotatably connected to the first mounting plate 521 via a first bearing 53, and the mounting shaft 42 is rotatably connected to the second mounting plate 522 via a second bearing 54.
