Description

Technical Field

[0001] The embodiments of this application relate to the field of battery manufacturing technology, and more specifically, this application relates to a printing table and a screen printing machine with an adsorption conveyor. Background Technology

[0002] In the photovoltaic field, screen printing is often used to fabricate grid electrodes on the surface of photovoltaic cells during the manufacturing process. Specifically, screen printing involves using a squeegee to evenly coat the surface of the cell with a paste through a screen, thereby completing the electrode printing.

[0003] Currently, the linear screen printing machines commonly used in the industry consist of a printing mechanism and a printing table for carrying the solar cells. The printing table surface has two horizontally continuous grooves. When the printing table moves under the printing mechanism, the squeegee of the printing mechanism descends from above and contacts one end of the screen, then moves laterally until the squeegee moves to the other end of the screen, allowing the ink to pass through the screen and be printed onto the surface of the solar cell. Finally, the squeegee rises and returns to its original position, thus completing the printing of the solar cell.

[0004] However, the area where the squeegee contacts the screen (the lower cutter position) is more prone to cracking than other areas, causing the ink to leak into the grooves of the existing printing table. This requires a lot of time to stop and clean, delaying production. Utility Model Content

[0005] This application aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention provides a printing table and an upper suction conveyor screen printing machine to ensure that when the screen is damaged, the leaked ink will not fall into the groove.

[0006] To solve the above problems, the technical solution adopted in this application is as follows:

[0007] On one hand, this utility model discloses a printing table, which is at least used to support the battery cell to be printed below the printing mechanism for printing by the printing mechanism. The bearing surface of the printing table includes a first region and a second region that are adjacent to each other along a first horizontal direction. The first region is a flat squeegee cutting position. The second region is provided with at least one groove for cooperating with loading and unloading. One end of the groove extends along the first horizontal direction to the edge of the upper surface of the bearing surface, and the other end of the groove extends away from the first horizontal direction to the edge of the first region.

[0008] The printing table provided in this application, by setting a first area without grooves and a second area with grooves, and making the first area correspond to the cutting position, ensures that even when the screen breaks, the problem of time-consuming and laborious cleaning caused by the paste falling into the grooves can be effectively avoided.

[0009] In one embodiment, the bearing surface is a transparent or semi-transparent structure, and a light source is disposed below the bearing surface.

[0010] The printing table's support surface is made of a transparent or semi-transparent structure. With the light source located below the support surface, it can assist the positioning camera in taking pictures, thereby achieving precise positioning of the battery cells to be printed and ensuring the smooth progress of the printing work.

[0011] In one embodiment, the bearing surface is provided with adsorption holes for adsorbing battery cells, and the adsorption holes are connected to an air cavity, which is connected to a negative pressure air source for adsorbing and fixing the battery cells to be printed.

[0012] The printing table has adsorption holes on its bearing surface. These adsorption holes are connected to the air cavity formed by the interlocking of the aluminum base and glass bearing surface of the printing table. The air cavity is connected to a negative pressure air source. The negative pressure adsorption principle can be used to adsorb and fix the battery cells to be printed, preventing the battery cells from shifting during printing or transportation.

[0013] On the other hand, this utility model also discloses an upper adsorption conveying screen printing machine, which includes a printing mechanism, a driving mechanism, a feeding mechanism, a printing table as described above, and a discharging mechanism arranged sequentially along a first horizontal direction, wherein:

[0014] The printing mechanism includes a squeegee, a squeegee driving assembly, and a screen assembly for fixing the screen. The squeegee driving assembly is at least used to drive the squeegee to descend and contact a first side of the screen and drive the squeegee to move along a first horizontal direction to a second side of the screen to complete the printing. The first side of the screen is close to the feeding mechanism, and the second side of the screen is away from the feeding mechanism.

[0015] The driving mechanism includes a transverse driving module that drives the printing table to move laterally along a first horizontal direction, and a lifting driving module that drives the printing table to move up and down along the squeegee descent direction.

[0016] The feeding mechanism includes an overhead conveyor assembly. The discharge end of the overhead conveyor assembly is located at the feeding station. The overhead conveyor assembly is used to adsorb and convey the battery cells to be printed to the printing table located at the feeding station.

[0017] The screen printing machine with upper adsorption conveyor provided in this application, utilizing the printing table structure described above, can effectively prevent the paste from falling into the groove, reduce cleaning and maintenance time, and improve production efficiency; while the upper suspension conveyor assembly is installed on the battery cell feeding side of the screen printing machine, which facilitates adsorption and holding of the battery cell to be printed on the belt surface and lateral conveying, improving the convenience of battery cell feeding and transfer.

[0018] In one embodiment, the unloading mechanism includes a thin belt conveyor assembly, the loading end of which is located at the unloading station. During unloading, the loading end of the thin belt conveyor assembly can extend horizontally into the groove and rise from the groove to obtain the printed battery cell located on the printing table.

[0019] The thin belt conveyor component in the feeding mechanism can extend into the groove of the printing table bearing surface and can rise relatively from the groove, thereby transferring the solar cells from the printing table to the thin belt conveyor component, achieving the purpose of efficient feeding and transfer of the printed solar cells.

[0020] In one embodiment, the overhead conveyor assembly includes:

[0021] Two conveying units, each conveying unit being used to adsorb and contact the upper surface of the battery cell to be printed;

[0022] support;

[0023] Two limiting plates are mounted on the bracket.

[0024] Two connecting plates, one end of which is adjustablely connected to two limiting plates, and the other end of which is fixedly connected to two conveying units. The connecting plates are used to adjust the distance between the two conveying units.

[0025] The drive unit is mounted on the bracket and is connected to each conveying unit. The drive unit is used to drive the conveying unit to convey the battery cells to be printed along the first horizontal direction to the printing table located above the loading station.

[0026] In the upper-suspended conveyor assembly, the limiting plate is fixedly mounted on the bracket, and a connecting plate is provided to be adjustablely connected to the limiting plate, so as to adjust the distance between the two conveying units by adjusting the relative position of the limiting plate and the connecting plate.

[0027] Optionally, the overhead conveyor assembly may also include a positioning component, which includes:

[0028] The ruler is mounted on the bracket;

[0029] Two indicator arrows are respectively set on the two conveyor units and point to the scale;

[0030] The indicator arrows, in conjunction with the scale, show the spacing between two adjacent conveyor units.

[0031] By setting a positioning component on the overhead conveyor assembly that includes an indicator arrow and a ruler, the distance between two adjacent conveyor units can be indicated in real time, and it is also convenient to guide the staff to accurately adjust the distance between two adjacent conveyor units.

[0032] Further optional, the overhead conveyor assembly also includes:

[0033] A slide rail extends along a second horizontal direction and is positioned below the scale; the second horizontal direction is perpendicular to the first horizontal direction.

[0034] Two sliders are slidably mounted on a slide rail.

[0035] The first mounting block is fixedly connected to the slider and the conveying unit respectively;

[0036] The indicator arrow is mounted inside the conveying unit via the first mounting block.

[0037] By setting the slider to slide on the slide rail, the movement of the two conveying units can be made smoother and more fluid when adjusting the distance between two adjacent conveying units.

[0038] In one embodiment, the conveying unit includes:

[0039] A cavity support has at least one groove on its lower surface, the groove extending along a first horizontal direction;

[0040] The transmission component is rotatably mounted at both ends of the cavity support, and the axis of rotation of the transmission component is along the second horizontal direction;

[0041] The second mounting block is embedded in the groove, and at the two sides of the groove, the second mounting block forms a slit between the two opposite inner walls of the groove to allow gas to flow.

[0042] The belt is fitted onto the transmission component and located in the middle of the slits on both sides. Driven by the transmission component, the lower side of the belt moves cyclically along the lower surface of the second mounting block.

[0043] Multiple air nozzles are mounted on the cavity support and arranged along the first horizontal direction. Each air nozzle is connected to a corresponding slit. The air nozzles can controllably inject high-pressure air into the slits, causing the slits to blow high-pressure air out along the surface of the cell to be printed. Finally, using Bernoulli's principle, the cell to be printed is attracted to the belt and transported by the moving belt.

[0044] The conveying unit injects preset high-pressure air into the slits on both sides of the belt through air nozzles. Utilizing Bernoulli's principle, the difference in flow velocity generates an adsorption force, which in turn adsorbs the battery cells to be printed onto the belt and moves them for transport, thus realizing the top adsorption conveying of the battery cells to be printed.

[0045] In a preferred embodiment, the drive unit is connected to the transmission component at the feed end of the suspended conveyor assembly via a synchronous belt pulley structure to drive the belt to convey along the first horizontal direction.

[0046] The motor drives the belts on two conveyor units simultaneously through a synchronous pulley structure, which ensures the synchronicity and stability of the two adjacent conveyor units when conveying the cells to be printed.

[0047] Optionally, multiple air nozzles are divided into multiple groups, and each group of air nozzles can independently control the injection of high-pressure air at a preset pressure.

[0048] Optionally, the lower surface of the cavity support is provided with at least two grooves, which are arranged sequentially from the feed end of the upper suspended conveying assembly to the discharge end of the upper suspended conveying assembly, and each groove is connected to a set of air nozzles.

[0049] In one embodiment, each group of air nozzles includes 2 to 5 adjacent air nozzles, and the number of air nozzles in each group is equal.

[0050] Multiple air nozzles arranged along the length of the cavity support of the conveyor are set as a group of 2-5 adjacent nozzles. Each group can be independently controlled and injected with preset high-pressure air. When conveying the battery cell to be printed, only the group of air nozzles corresponding to the position of the battery cell will be injected with high-pressure air, thereby ensuring that the battery cell to be printed is successfully adsorbed and held on the belt surface and moved laterally.

[0066] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0067] like Figure 1 and Figure 2 The printing table shown, in which, Figure 1 This is a schematic diagram of the three-dimensional structure of the printing table. Figure 2 This is a top view of the printing table.

[0068] In this application, the applicant proposes a printing table 4, which is at least used to support battery cells below a printing mechanism 1 for printing by the printing mechanism 1. The printing table 4 includes an aluminum base 41 and a glass-type support surface 42 disposed above the aluminum base 41. The support surface 42 of the printing table 4 includes a first region 421 and a second region 422 disposed adjacent to each other along a first horizontal direction, wherein the first region 421 is directly below the area where the squeegee 11 of the printing mechanism 1 descends and contacts the screen, that is, directly below the cutting position. The second region 422 is provided with at least one groove 4221 for coordinating loading and unloading, one end of the groove 4221 extending along the first horizontal direction to the edge of the upper surface of the support surface 42, and the other end of the groove 4221 extending away from the first horizontal direction to the edge of the first region 421.

[0069] In the prior art, when the printing table 4 moves below the printing mechanism 1, the squeegee 11 of the printing mechanism 1 descends from one end to contact the screen, then moves horizontally across the screen, and finally rises and returns to its original position. Therefore, during long-term use, the area of ​​the screen pressed down by the squeegee 11 is prone to cracking, causing the ink to leak out to the printing table 4. Its bearing surface 42 is divided into a lower cutting position (i.e., the first area 421) and a groove 4221 area (i.e., the second area 422) that are adjacent to each other along the first horizontal direction. This prevents the ink from falling into the groove 4221 when the lower cutting position area of ​​the screen cracks after long-term printing work, thereby avoiding the time-consuming and laborious problem of ink cleaning and improving production efficiency.

[0070] Combined with appendix Figure 1 and attached Figure 2 As shown, in one embodiment, the bearing surface 42 is a transparent or semi-transparent glass structure, and a light source is disposed inside the air cavity below the bearing surface 42. The light source illuminates the transparent or semi-transparent glass bearing surface 42 to assist the positioning camera 6 in taking pictures.

[0071] Combined with appendix Figure 1 and attached Figure 2 As shown, in one embodiment, multiple adsorption holes 4223 for adsorbing battery cells can be arrayed on the surface of the bearing surface 42, and an air cavity is formed in the space formed by the fastening of the aluminum base 41 and the bearing surface 42. One end of the air cavity is connected to the air passage of the adsorption hole 4223, and the other end is connected to the air passage of the negative pressure air source. By using the principle of vacuum adsorption, the battery cells to be printed can be adsorbed and fixed, preventing the battery cells from shifting during the transportation or printing process.

[0072] Based on the same concept, this embodiment also provides a screen printing machine with an upper adsorption conveyor. For example... Figures 3-5 As shown, where, Figure 3 This is a schematic diagram of the overall structure of a screen printing machine with an upper adsorption conveyor. Figure 4 This is a schematic diagram of part of the structure of a screen printing machine with an upper adsorption conveyor system, from material loading to printing. Figure 5 This is a partial structural diagram of a screen printing machine with an upper adsorption conveyor along the first horizontal direction.

[0073] In this application, the applicant proposes a screen printing machine with an upper adsorption conveyor, combined with the attached... Figure 3 As shown, the screen printing machine includes a printing mechanism 1, a driving mechanism 2, a feeding mechanism 3, a printing table 4, and a discharging mechanism 5 arranged sequentially along a first horizontal direction, wherein:

[0074] The printing mechanism 1 includes a squeegee 11, a squeegee drive assembly 12, and a screen assembly 13 for fixing the screen. The squeegee drive assembly 12 is used to drive the squeegee 11 to descend and contact the first side of the screen and drive the squeegee 11 to move along the first horizontal direction to the second side of the screen to complete the printing. The first side of the screen is close to the feeding mechanism 3, and the second side of the screen is away from the feeding mechanism 3.

[0075] like Figure 4 As shown, the drive mechanism 2 includes a transverse drive module that drives the printing table 4 to move laterally along the first horizontal direction, and a lifting drive module that drives the printing table 4 to move up and down along the downward direction of the squeegee 11.

[0076] like Figure 4 As shown, the feeding mechanism 3 includes an upper suspension conveying component 31. The discharge end of the upper suspension conveying component 31 is located at the feeding station. The upper suspension conveying component 31 is used to adsorb and convey the battery cells to be printed to the printing table 4 located at the feeding station.

[0077] like Figure 4-7 As shown, the battery cells to be printed are conveyed along a belt conveyor line, with the discharge end of the belt conveyor line corresponding to the loading section of the overhead conveyor assembly 31. When the battery cell moves to the loading end of the belt conveyor line, the overhead conveyor assembly 31 activates its adsorption function, and the battery cell to be printed is picked up and attached to the belt 323 of the overhead conveyor assembly 31. The overhead conveyor assembly 31 maintains its adsorption force and rotates the belt 323, so that the battery cell to be printed is conveyed to the printing table 4 at the loading station of the discharge end of the overhead conveyor assembly 31.

[0078] The printing table 4 is driven by the drive mechanism 2 to the discharge end of the upper suspension conveyor 31. Then the upper suspension conveyor 31 releases its adsorption, allowing the battery cell to fall onto the printing table 4. The adsorption holes 4223 on the bearing surface 42 of the printing table 4 adsorb and fix the battery cell to be printed. Then it is photographed by the positioning camera 6. After that, the printing table 4 moves to the area below the screen printing mechanism.

[0079] The general operation of the screen printing machine provided in this application is as follows: The battery cell to be printed is conveyed to the printing table 4 by the feeding mechanism 3. Then, the battery cell to be printed is photographed by the positioning camera 6 to obtain position information. The drive mechanism 2 drives the printing table 4 to move laterally. The screen assembly 13 in the printing mechanism 1 adjusts the screen position according to the position information to keep it aligned with the battery cell to be printed. Then, the squeegee 11 performs the screen printing operation. The squeegee 11 first descends to the lower position to contact the screen, then moves laterally, and finally rises back to its original position to complete the printing of the battery cell. After the screen printing is completed, the drive mechanism 2 continues to drive the printing table 4 to move laterally to the unloading mechanism 5 and descends. The battery cell remains on the unloading mechanism 5 and is then conveyed. The output detection mechanism 7 performs output detection on each printed battery cell that passes by.

[0080] Combined with appendix Figure 5 As shown, in one embodiment, the unloading mechanism 5 includes a thin belt conveyor assembly 51, the loading end of which is located at the unloading station, and during unloading, the loading end of the thin belt conveyor assembly 51 can extend into the groove 4221 and rise from the groove 4221 to obtain the printed battery cell located on the printing table 4.

[0081] It should be noted that the actions of the thin belt conveyor assembly 51 extending into the groove 4221 and rising from the groove 4221 to obtain the printed battery cell on the printing table 4 are relative movements. That is, the thin belt conveyor assembly 51 is driven to move while the printing table 4 remains stationary; or, the thin belt conveyor assembly 51 remains stationary while the printing table 4 is driven to move. Both methods can achieve the transfer of the battery cell from the printing table 4 to the thin belt conveyor assembly 51. Specifically, in one embodiment, when the unloading mechanism 5 unloads the material, the drive mechanism 2 drives the printing table 4 to the thin belt conveyor assembly 51 of the unloading mechanism 5, and continues to drive the printing table 4 to gradually move laterally along the first horizontal direction, so that the thin belt conveyor assembly 51 extends into the channel 43 from the inlet of the channel 43. Then, the drive mechanism 2 drives the printing table 4 to gradually descend, so that the thin belt conveyor assembly 51 floats relatively upward away from the bearing surface 42 of the printing table 4, lifting the printed battery cell. Then, the printed battery cell continues to be conveyed backward, and after being photographed by the output detection camera, it is conveyed to the next process. In another embodiment, when the feeding mechanism 5 feeds the material, the driving mechanism 2 drives the printing table 4 to the fine belt conveyor assembly 51 of the feeding mechanism 5 and then stops moving laterally. The fine belt conveyor assembly 51 moves laterally in a direction away from the first horizontal direction so that the fine belt conveyor assembly 51 extends into the channel 43 from the inlet of the channel 43. Then the fine belt conveyor assembly 51 gradually rises so that the fine belt conveyor assembly 51 floats relatively away from the bearing surface 42 of the printing table 4 to support the printed battery cell.

[0082] Combined with appendix Figure 6-8As shown, in one embodiment, the overhead conveying assembly 31 includes: two conveying units 311, each conveying unit 311 being used at least to adsorb and contact the upper surface of the battery cell to be printed; a support 312; two limiting plates 313, both of which are disposed on the support 312; two connecting plates 314, one end of each connecting plate 314 being adjustablely connected to the two limiting plates 313, and the other end of each connecting plate 314 being fixedly connected to the two conveying units 311, the connecting plates 314 being used to adjust the distance between the two conveying units 311; and a driving unit 315, the driving unit 315 being mounted on the support 312 and drivenly connected to each conveying unit 311, the driving unit 315 being used to drive the conveying units 311 to convey the battery cell to be printed along a first horizontal direction to above the printing table 4 located at the loading station. Specifically, as shown... Figure 6 As shown, Figure 6 This is a schematic diagram of the feeding section of a screen printing machine with an upper adsorption conveyor.

[0083] In specific implementation, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the overhead conveyor assembly. A slotted through-hole is provided on the limiting plate 313 to facilitate adjustment of the relative position of the limiting plate 313 and the connecting plate 314. The specific operation is as follows: loosen the screws between the limiting plate 313 and the connecting plate 314; adjust the mounting block according to the distance to position the two conveying units 311 in a predetermined position; tighten the screws between the limiting plate 313 and the connecting plate 314 to fix the two conveying units 311 in the predetermined suitable position.

[0084] In the upper suspended conveying assembly 31, the limiting plate 313 is fixedly mounted on the bracket 312, and the connecting plate 314 is provided to be adjustablely connected to the limiting plate 313, so that the distance between the two conveying units 311 can be adjusted by adjusting the relative position of the limiting plate 313 and the connecting plate 314.

[0085] Combined with appendix Figure 7 and attached Figure 8 As shown, in one embodiment, to facilitate accurate adjustment of the distance between two adjacent conveying units 311 to a suitable distance, the upper-suspended conveying assembly 31 further includes a positioning assembly 316. The positioning assembly 316 includes: a scale 3161 mounted on a bracket 312; and two indicator arrows 3162 respectively disposed on the two conveying units 311 and pointing towards the scale 3161. The indicator arrows 3162 cooperate with the scale 3161 to indicate the distance between two adjacent conveying units 311, thereby facilitating worker adjustment of the distance between the two adjacent conveying units 311. Specifically, as shown... Figure 8 As shown, Figure 8 This is a schematic diagram of the structure of the suspended conveyor assembly when viewed from the first horizontal direction.

[0086] By setting a positioning component 316 on the upper suspended conveying component 31, which includes an indicator arrow 3162 and a ruler 3161, the distance between two adjacent conveying units 311 can be indicated in real time, and it is also convenient to guide the staff to accurately adjust the distance between two adjacent conveying units 311.

[0087] Combined with appendix Figure 8 As shown, in one embodiment, in order to adjust the spacing between two adjacent conveying units 311 more smoothly, the upper-suspended conveying assembly 31 further includes: a slide rail 317, which extends along a second horizontal direction and is disposed below the scale 3161, the second horizontal direction being perpendicular to the first horizontal direction; two sliders 318, which are slidably disposed on the slide rail 317; a first mounting block, which is fixedly connected to the sliders 318 and the conveying unit 311 respectively; and an indicator arrow 3162, which is mounted on the inner side of the conveying unit 311 through the first mounting block.

[0088] By setting the slider 318 to slide on the slide rail 317, the movement of the indicator arrow 3162 can be smoother and more fluid when adjusting the distance between two adjacent conveying units 311.

[0089] Combined with appendix Figure 9 As shown, Figure 9 The following is a bottom view of the conveying unit. In one embodiment, the conveying unit 311 includes: a cavity support 319, the lower surface of which has at least one groove 320 extending along a first horizontal direction; a transmission member 321, rotatably disposed at both ends of the cavity support 319, with the axis of rotation of the transmission member 321 along a second horizontal direction; a second mounting block 322, embedded in the groove 320, and forming slits for gas flow between the second mounting block 322 and two opposing inner walls of the groove 320 at positions on both sides of the groove 320; and a belt 323. The belt 323 is mounted on the transmission component 321 and located in the middle of the slits on both sides. Driven by the transmission component 321, the lower side of the belt 323 moves cyclically along the lower surface of the second mounting block 322. Multiple air nozzles 324 are mounted on the cavity support 319 and arranged along the first horizontal direction. The multiple air nozzles 324 are connected to each slit. The air nozzles 324 can controllably inject high-pressure air into the slits, so that the slits blow high-pressure air out along the surface of the battery cell to be printed. Finally, using Bernoulli's principle, the velocity difference generates an adsorption force, so that the battery cell to be printed is adsorbed on the belt 323 and transported by the moving belt 323.

[0090] Figure 9In this embodiment, the transmission component 321 is a roller. However, it should be noted that in specific implementation, the transmission component 321 is not limited to the form of a flat roller. Any transmission component 321 that can cause the belt 323 to move cyclically along the lower surface of the second mounting block 322 after being driven can be used. For example, it can also be a drum-shaped roller.

[0091] The conveying unit 311 injects preset high-pressure air into the slits on both sides of the belt 323 through the air nozzle 324. By utilizing Bernoulli's principle, an adsorption force is generated through the velocity difference, which can then adsorb the battery cell to be printed onto the belt 323 and move it for conveying, thus realizing the top adsorption conveying of the battery cell to be printed.

[0092] Combination Figure 6 and Figure 7 As shown, in one embodiment, the drive unit 315 is connected to the transmission member 321 at the feed end of the suspended conveyor assembly 31 via a synchronous pulley structure 325 to drive the belt 323 to convey along the first horizontal direction.

[0093] The motor drives the belts 323 on the two conveying units 311 simultaneously through the synchronous pulley structure 325, which can ensure that the two adjacent conveying units 311 can maintain synchronous traction of each part when conveying the same battery cell to be printed, thereby ensuring the stability of the battery cell to be printed during the conveying process.

[0094] Combined with appendix Figure 9 As shown, in one embodiment, the lower surface of the cavity support 319 is provided with at least two grooves 320, which are arranged sequentially from the feed end of the upper suspended conveying assembly 31 to the discharge end of the upper suspended conveying assembly 31. Each groove 320 is connected to a set of air nozzles 324. It should be noted that the specific number of grooves 320 is not limited in specific implementation.

[0095] Combined with appendix Figure 10 As shown, in one embodiment, multiple air nozzles 324 are divided into multiple groups, and each group of air nozzles 324 can independently control the injection of high-pressure air at a preset pressure.

[0096] Combined with appendix Figure 10 As shown, in one embodiment, each group of air nozzles 324 includes 2 to 5 adjacent air nozzles 324, and the number of air nozzles 324 in each group is equal. It should be noted that in specific implementations, the specific number of air nozzles 324 in each group is not limited, as long as it ensures that multiple air nozzles 324 in each group can be independently controlled to inject a preset high-pressure air. For example, it can be a group of 3 adjacent air nozzles 324, or it can be a group of 5 adjacent air nozzles 324.

[0097] In addition, when conveying the battery cells, only one set of air nozzles 324 corresponding to the position of the battery cell will be injected with high-pressure air. The battery cell is adsorbed and held on the surface of the belt 323 and moved laterally. That is, generally only the current position of the battery cell is generated with adsorption force, which can ensure that the battery cell to be printed is successfully adsorbed and held on the surface of the belt 323 and moved laterally.
