DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] In this application, terms such as "upper," "front," "rear," and "inner" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to specific positions, or to their construction or operation in a specific position.

[0033] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0034] Furthermore, the terms "installed," "disposed," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0035] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0036] Screen printing is a core process in the solar cell manufacturing process. It utilizes the principle that the patterned mesh allows the slurry to pass through, while the non-patterned mesh remains impermeable. It is widely used to coat photosensitive materials and metal electrodes on silicon wafers. The quality of screen printing directly impacts the quality of solar cells. Debris or foreign matter adhering to the cell surface before printing can be difficult to detect during normal processing, making it difficult to stop and clean the process. Furthermore, the random presence of debris and foreign matter can easily lead to screen cracking, screen leakage, or even widespread cracking during printing, reducing the screen's lifespan.

[0037] To solve the above problem, the inventors tried to clean the battery cells before they were transferred to the printing mechanism. By setting an air knife upstream of the printing mechanism, the wind was used to blow away the debris or foreign matter attached to the battery cells, thereby achieving the purpose of cleaning the battery cells. However, after long-term research, the inventors found that the air knife can only blow away some of the debris and foreign matter on the battery cells, although it improves the surface cleanliness of the battery cells to a certain extent. However, due to the strong adhesion of debris or foreign matter on the battery cells, the blowing of conventional air knives cannot completely remove foreign matter on the surface of the battery cells. And because the battery cells are relatively thin, increasing the wind pressure may cause small cracks in the battery cells due to excessive wind pressure, which may further damage the battery cells.

[0038] In view of this, an embodiment of the present application provides a battery cell printing device that can clean the surface of the battery cell and effectively remove debris or foreign matter attached to the surface of the battery cell. That is, the battery cell printing device of the present application can reduce the occurrence of problems such as screen explosion, slurry leakage or batch hidden cracks, which is conducive to improving the service life of the screen.

[0039] The technical solution of the present application is further described below through specific embodiments and drawings.

[0040] See also Figure 1 , Figure 1 The present invention discloses a cell printing device 100, which includes a transmission mechanism 1, a cleaning mechanism 2, and a printing mechanism 3. The transmission mechanism 1 has a transmission surface M (e.g., Figure 1As shown in the dashed box in FIG, the conveying mechanism 1 is configured to convey the battery cells. The cleaning mechanism 2 includes a fixed bracket 21 and a cleaning assembly 22. The fixed bracket 21 is disposed above the conveying mechanism 1. The cleaning assembly 22 is movably disposed on the fixed bracket 21. The cleaning assembly 22 can move relative to the fixed bracket 21 along a first direction Y to approach or move away from the conveying surface M. When the cleaning assembly 22 approaches the conveying surface M, the cleaning assembly 22 is configured to contact the battery cells on the conveying surface M to clean the battery cells. The printing mechanism 3 is located downstream of the cleaning mechanism 2 along the conveying direction X of the conveying mechanism 1. The printing mechanism 3 is configured to print the cleaned battery cells. The first direction Y is the height direction of the conveying mechanism 1.

[0041] Since the printing mechanism 3 is located downstream of the cleaning mechanism 2 along the transmission direction X of the transmission mechanism 1, and the cleaning component 22 can move along the first direction Y relative to the fixed bracket 21, when the battery cell passes through the cleaning mechanism 2, the distance between the cleaning component 22 and the battery cell is adjusted so that the cleaning component 22 can contact the surface of the battery cell, thereby cleaning foreign matter on the surface of the battery cell, effectively improving the surface cleanliness of the battery cell transmitted to the printing mechanism 3 through the transmission mechanism 1, and helping to reduce the occurrence of problems such as damage to the printing screen, thereby helping to increase the service life of the screen and reduce production costs; at the same time, it is also helpful to reduce the frequency of screen replacement and improve production efficiency.

[0042] In some embodiments, the cleaning mechanism 2 further includes a drive assembly 23 , which is fixed to the fixed bracket 21 and connected to the cleaning assembly 22 . The drive assembly 23 is configured to drive the cleaning assembly 22 to move along the first direction Y. By driving the cleaning assembly 22 via the drive assembly 23 , on the one hand, the cleaning assembly 22 can be moved toward or away from the transport surface M along the first direction Y; on the other hand, the drive assembly 23 makes the movement of the cleaning assembly 22 more controllable.

[0043] It is understood that the movement of the cleaning assembly 22 relative to the fixing bracket 21 along the first direction Y can be driven electrically or manually. In other words, the driving assembly 23 can be driven electrically or manually.

[0044] Combine Figures 2 to 3 , Figure 2 This is a schematic structural diagram from a first perspective of the cleaning mechanism disclosed in an embodiment of the present application; Figure 32 is a schematic structural diagram of the cleaning mechanism (column omitted) disclosed in an embodiment of the present application from a second perspective. As an example, the drive assembly 23 can be a manual drive assembly, for example, the drive assembly 23 can include a knob 231, a gear 232, and a rack 233. The knob 231 is disposed on the fixed bracket 21. The knob 231 is provided with a rotating shaft 2311, which passes through the fixed bracket 21. The gear 232 is sleeved on the rotating shaft 2311. The rack 233 is disposed on the cleaning assembly 22 and meshes with the gear 232. The knob 231 is configured to drive the rotating shaft 2311 and the gear 232 to rotate, so that the rack 233 moves and drives the cleaning assembly 22 to move along the first direction Y.

[0045] In this way, through the cooperation of the knob 231, the gear 232 and the rack 233, on the one hand, the driving of the cleaning component 22 is realized; on the other hand, by manually turning the knob 231, the movement of the cleaning component 22 can be finely adjusted, which is convenient for adjusting the movement of the cleaning component 22 along the first direction Y at any time according to the specific operating conditions of the battery cell printing device, so that the distance between the cleaning component 22 and the transmission surface M is appropriate.

[0046] As another example, when the driving assembly 23 is a manual driving assembly, the driving assembly 23 may also include an eccentric turntable and a connecting rod. The eccentric turntable is arranged on the fixed bracket 21, and the axis of the eccentric turntable is arranged along the transmission direction X. One end of the connecting rod is rotatably connected to the eccentric shaft of the eccentric turntable, and the other end is rotatably connected to the cleaning assembly 22. The eccentric turntable is configured to drive the connecting rod to swing so that the connecting rod drives the cleaning assembly 22 to move along the first direction Y. Through the cooperation of the eccentric turntable and the connecting rod, while achieving the driving of the cleaning assembly 22, the surface contact between the eccentric turntable and the connecting rod, and the surface contact between the connecting rod and the cleaning assembly 22 can reduce the wear of the driving assembly 23, increase the service life of the driving assembly 23, and reduce the frequency of overhaul and maintenance, which is conducive to improving the working efficiency of battery cell printing.

[0047] Of course, it is understood that, as another example, when the drive assembly 23 is electrically driven, the drive assembly 23 may include a cylinder, which is fixed to the fixed bracket 21, and the drive end of the cylinder is connected to the cleaning assembly 22, and the cylinder is configured to drive the cleaning assembly 22 to move along the first direction Y. By driving the movement of the cleaning assembly 22 by the cylinder, no additional transmission structure is required, making the overall structure of the cell printing device 100 simpler, which helps to simplify the assembly process of the cell printing device.

[0048] As another example, when the drive assembly 23 is electrically driven, the drive assembly 23 may include a motor and a ball screw. The motor is fixed to the fixed bracket 21. The ball screw includes a screw and a nut. The screw and the nut are threadedly connected. The motor is in driving connection with the screw. The nut is fixedly connected to the cleaning assembly 22. The motor is configured to drive the screw to rotate, thereby driving the nut and the cleaning assembly 22 to move along the first direction Y. Using the motor to drive the movement of the cleaning assembly 22 can make the movement process more controllable. At the same time, using the ball screw to transmit the driving force can reduce the friction of the transmission, improve the transmission accuracy, and make the transmission more stable.

[0049] Optionally, the motor includes a servo motor, a forward and reverse motor, etc., which is not limited in this embodiment.

[0050] In some embodiments, the fixed bracket 21 is provided with a slide 211 and an axial hole 212. The slide 211 extends along the first direction Y. The axial hole 212 is connected to the slide 211. The rotating shaft 2311 is disposed in the axial hole 212 and extends into the slide 211. The gear 232 is sleeved on one end of the rotating shaft 2311 located in the slide 211. The rack 233 is located in the slide 211 and meshes with the gear 232 to drive the cleaning assembly 22 to move along the first direction Y. In this way, the gear 232 and the rack 233 of the driving assembly 23 are disposed in the slide 211 via the slide 211 and the axial hole 212. On the one hand, this realizes the connection between the driving assembly 23 and the cleaning assembly 22, while making the structure of the cleaning mechanism 2 more compact. On the other hand, the extension of the slide 211 along the first direction Y can guide the movement of the cleaning assembly 22, so that the movement of the cleaning assembly 22 will not be deviated.

[0051] Optionally, the fixed bracket 21 includes a bracket body 21a and two uprights 21b, the two uprights 21b being respectively disposed on either side of the conveying mechanism 1 along a second direction Z. The bracket body 21a is connected to the two uprights 21b so as to straddle the conveying surface M, and the cleaning assembly 22 is movably connected to the bracket body 21a, wherein the second direction Z intersects the conveying direction X of the conveying mechanism 1. The uprights 21b allow the bracket body 21a to straddle the conveying mechanism 1. Thus, on the one hand, the uprights 21b on either side of the conveying mechanism 1 secure the bracket body 21a, and the connection between the two sides provides a more secure connection. On the other hand, the straddle arrangement allows the conveying mechanism 1 to pass through the cleaning mechanism, making the structural layout of the cell printing device more centralized and compact. Furthermore, the cleaning mechanism 2 can be directly aligned with the cells on the conveying mechanism 1 for cleaning without the need for additional positioning structures. This simplifies the overall structure of the cell printing device 100, reduces component assemblies, and facilitates a simplified assembly process for the cell printing device.

[0052] Optionally, the support body 21a may be a block structure or a plate structure. Figure 2 As shown, the bracket body 21a can be a square block structure, having two first end surfaces sequentially arranged along the transmission direction X and two second end surfaces arranged along the first direction Y. The chute 211 is provided on the first end surface, and the chute 211 penetrates the two second end surfaces of the bracket body 21a along the first direction Y. In this way, with the chute 211 penetrating the second end surfaces, on the one hand, the rack can be installed in the chute 211 through the penetration of the second end surface, which can facilitate the installation of the rack 233. On the other hand, the penetration provides space for the rack 233 to move in the first direction Y, so that when the gear 232 drives the rack 233 to move in the first direction Y, the rack 233 will not collide with the bracket body 21a, which is beneficial to improving the smooth movement of the cleaning assembly 22 and avoiding damage to the drive assembly 23 and the fixed bracket 21.

[0053] It is understandable that the sliding groove 211 can be provided on any one of the two first end surfaces, and this embodiment does not limit this.

[0054] Optionally, the bracket body 21a further has a third end face arranged along the second direction Z, and the shaft hole 212 is arranged on the third end face. The shaft hole 212 on the third end face can provide support for the rotating shaft 2311. It can be understood that the shaft hole 212 can be provided on any one of the two third end faces, or both third end faces are provided with shaft holes 212. Exemplarily, there are two knobs 231, and both third end faces are provided with shaft holes 212. The rotating shaft 2311 is passed through the two shaft holes 212, and the two knobs 231 are respectively connected to the two ends of the rotating shaft 2311. Providing support for the rotating shaft 2311 by the shaft holes 212 on the two third end faces can prevent the rotating shaft 2311 from tilting, which is conducive to improving the stability of the drive assembly 23.

[0055] Please combine Figure 4 and Figure 5 , Figure 4 yes Figure 3 A partial enlarged view of point A in the middle; Figure 4 yes Figure 3A partial enlarged view of point B in the figure. As an optional embodiment, the cleaning assembly 22 includes a sliding member 221 and a cleaning member 222. The sliding member 221 has a protrusion 2211 formed on a side facing the slide groove 211. The protrusion 2211 has a plurality of tooth-like structures spaced apart along the first direction Y to form a rack 233. The sliding member 221 is configured to move along the first direction Y driven by the rack 233, thereby causing the cleaning member 222 to move along the first direction Y. The cleaning component 222 can be moved along the first direction Y by the sliding of the sliding component 221; at the same time, the cooperation between the protrusion 2211 of the sliding component 221 and the slide groove 211 guides the sliding of the sliding component 221, so that the sliding trajectory of the cleaning component 222 will not be offset and is more controllable; and, by arranging a plurality of tooth-like structures at intervals on the protrusion 2211 to form a rack 233, there is no need to additionally install the rack 233 on the sliding component 221, so that the connection between the rack 233 and the sliding component 221 is more stable, and at the same time, the assembly time of the cleaning mechanism 2 is saved, making the assembly more convenient.

[0056] Optionally, slide rails 2111 are provided on both side walls of the slide groove 211, and the side walls of the protrusion 2211 are slidably connected to the slide rails 2111. The sliding connection between the protrusion 2211 and the slide rails 2111 can provide support for the sliding member 221 along the transmission direction X, preventing the gear 232 and the rack 233 from squeezing each other and causing locking, thereby making the sliding member 221 slide more stable and smooth relative to the bracket body 21a; at the same time, the movement space of the sliding member 221 can be limited, preventing the sliding member 221 from separating from the slide groove 211 along the transmission direction X.

[0057] In some embodiments, a groove 2212 is provided on the end of the sliding member 221 facing the transmission surface M. The cleaning member 222 at least partially extends into the groove 2212. The sliding member 221 is also provided with a fastener 2213. The fastener 2213 is configured to securely connect the cleaning member 222 to the groove 2212. The cooperation between the groove 2212 and the fastener 2213 secures the cleaning member 222, making the connection between the cleaning member 222 and the sliding member 221 more secure. At the same time, the cleaning member 222 can move along with the sliding member 221. Furthermore, the groove 2212 can position the cleaning member 222 during installation, eliminating the need to adjust the position of the cleaning member 222 during installation, making installation more convenient.

[0058] Optionally, the groove 2212 includes a dovetail groove, a T-shaped groove, a rectangular groove, etc. For example, Figure 2 and Figure 3As shown, the groove 2212 is configured as a dovetail groove, and the sidewall surface of the dovetail groove can provide a supporting force for the cleaning component 222 along the first direction Y, so that the cleaning component 222 can be suspended above the transmission mechanism 1.

[0059] Optionally, the fasteners 2213 include splints, screws, latches, etc. For example, Figure 2 and Figure 3 As shown, fastener 2213 includes two clamping plates and a screw. The two clamping plates clamp the cleaning member 222, and the screw further secures the clamping of the two clamping plates. The clamping plates and screws work together to secure the connection of the cleaning member 222 and facilitate installation. Furthermore, the clamping plates can be used to secure the cleaning member 222 even if it is discontinuous along the second direction Z.

[0060] Of course, in other embodiments, the cleaning component may also be connected to the sliding component by a snap-fit ​​connection.

[0061] In some embodiments, the cleaning member 222 comprises at least one of cloth, paper, or a brush. Using cloth or paper as the cleaning member 222 allows for more flexible contact between the cleaning member 222 and the cell, preventing damage to the cell. Using a brush as the cleaning member 222 utilizes the brush's ability to remove stubborn debris, effectively cleaning stubborn debris or foreign matter with strong adhesion to the cell surface.

[0062] Exemplarily, the cleaning component 222 may be a non-woven fabric, which at least partially extends into the groove 2212, and the sliding component 221 moves along the first direction Y so that the non-woven fabric abuts against the surface of the battery cell. The non-woven fabric is used to achieve flexible cleaning and full-surface cleaning of the battery cell surface. Of course, as another example, the cleaning component 222 may also include a non-woven fabric and a soft brush at the same time, so that by combining the full-surface cleaning of the battery cell surface with the cleaning of stubborn debris or foreign matter by the non-woven fabric and the cleaning of stubborn debris or foreign matter by the soft brush, foreign matter on the surface of the battery cell can be better cleaned, which is beneficial to improving the surface cleanliness of the battery cell, thereby helping to avoid damage to the printing screen by the battery cell.

[0063] In some embodiments, the width of the cleaning member 222 is greater than the width of the cell along the width direction of the transport surface M. In this way, the cleaning member can cover the entire cell along the width direction of the transport surface M, so that the cleaning member 222 can fully clean the cell, which is beneficial to improving the surface cleanliness of the cleaned cell and thus helping to prevent the cell from damaging the printing screen.

[0064] Optionally, the cell printing device 100 further includes a frame 4, and the transmission mechanism 1 and the cleaning mechanism 2 are both disposed above the frame 4. The frame 4 provides support for the transmission mechanism 1 and the cleaning mechanism 2, thereby enabling the transmission mechanism 1 and the cleaning mechanism 2 to be installed.

[0065] Optionally, the printing mechanism 3 includes a turntable 31 and multiple printing stations 32 disposed on the turntable 31. Each printing station 32 is provided with a printing element, which is configured to print a battery cell. The multiple printing stations 32 of the printing mechanism 3 allow for simultaneous loading and unloading of materials during printing, thereby improving printing efficiency. Furthermore, the multiple printing stations 32 can also perform different printing processes simultaneously, further improving printing efficiency.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
