[0018] In some embodiments, the printing machine includes a turntable and at least one group of first printing stations connected to the turntable, and a first loading station, a first printing station, and a first unloading station are sequentially arranged on the rotating path of the turntable.

[0025] By setting a paper receiving station and controlling the first roller and the second roller to rotate at the paper receiving station, the contaminated roll paper that can no longer be used can be completely rolled up.

[0056] The above-mentioned objects, features and advantages of the present invention can be more clearly understood, and the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Existing screen printing equipment, during the printing process, generally uses a linear module in contact with one end of the screen to drive the screen assembly to rotate so as to adjust the angle of the screen assembly. The transmission structure of the linear module is complex, and it is difficult to accurately adjust the angle of the screen assembly.

[0058] In view of this, the present invention provides an improved cell printing device, which drives the screen assembly to rotate by setting a rotation drive mechanism in the printing device, thereby implementing angle adjustment of the screen assembly. Compared with traditional printing devices, its structure is simpler and the angle adjustment accuracy of the screen assembly is improved.

[0059] The cell printing device of the present invention will be described exemplarily by means of two embodiments.

[0060] First embodiment

[0061] like Figures 1 to 3 As shown, the cell printing device provided in this embodiment includes a loading mechanism 20, a printing machine 10, a printing device 30 and a unloading mechanism 40, wherein:

[0062] The loading mechanism 20 is located at the front of the printing machine 10 , and is used to load the battery cells to be printed onto the printing machine 10 .

[0063] The printing device 30 is arranged above the printing machine platform 10. Figures 4 to 5As shown, the printing device 30 includes a printing mechanism 32 and a rotating drive mechanism 33, wherein: the printing mechanism 32 includes a substrate 321, a screen assembly 322 and a scraper assembly 323, the screen assembly 322 is rotatably connected to the substrate 321 and is connected to the driving end of the rotating drive mechanism 33, the rotating drive mechanism 33 is used to drive the screen assembly 322 to rotate to adjust the angle of the screen assembly 322, and the scraper assembly 323 is used to print the material on the screen assembly 322 onto the battery cell on the printing machine 10.

[0064] The unloading mechanism 40 is located at the rear of the printing machine 10 , and is used to output the printed battery cells on the printing machine 10 .

[0065] It can be seen that a rotation driving mechanism 33 is provided in the printing device 30, which can drive the screen assembly 322 to rotate, thereby implementing an angle adjustment of the screen assembly.

[0066] In this way, when the feeding mechanism 20 feeds the battery cell to be printed onto the printing machine 10, the printing device 30 can actively adjust the angle of the screen assembly 322 according to the current angle of the battery cell to be printed, so that the screen assembly is aligned with the battery cell to be printed, thereby ensuring the printing effect. In addition, compared with the transmission structure of the traditional linear module, the rotary drive mechanism greatly improves the angle adjustment accuracy of the screen assembly 322.

[0067] Optional, such as Figure 4 As shown, the printing device 30 further includes a first mounting bracket 31. The substrate 321 is connected to the first mounting bracket 31. The rotation drive mechanism 33 includes a rotating motor 331 and a transmission member, wherein: the rotating motor 331 is arranged on the first mounting bracket 31, the first end of the transmission member is connected to the driving end of the rotating motor 331, the second end of the transmission member is connected to the screen assembly 322, and the rotating motor 331 drives the screen assembly 322 to rotate through the transmission member.

[0068] Optionally, the rotating motor 331 may be a DD motor, which has a built-in rotation angle detector, which can greatly improve the angle adjustment accuracy of the rotating drive mechanism 33 on the screen assembly 322, ensure that the screen assembly 322 is aligned with the battery cell, and improve printing accuracy.

[0069] Optionally, the rotation center of the rotating motor 331 and the rotation center of the screen assembly 322 are on the same vertical line. In this way, the driving stability of the rotating drive mechanism 33 on the screen assembly 322 can be further improved, preventing the screen assembly 322 from shaking due to inconsistent force during the rotation process, and ensuring that the screen assembly 322 rotates at the same angle as the rotating motor 331.

[0070] Before, during and after printing, it is often necessary to adjust the height of the screen assembly 322 in the vertical direction. Therefore, it is necessary to set the transmission member to achieve the freedom of contraction of the transmission member in the vertical direction, thereby ensuring that the transmission member can continuously transmit the rotational torque of the rotating motor 331 to the screen assembly 322.

[0071] Based on this consideration, optional Figure 5 As shown, the transmission member is configured as a link type structure capable of realizing telescopic movement in the vertical direction, and includes a first link 332, a second link 333 and a third link 334, wherein: the first end of the first link 332 is connected to the driving end of the rotating motor 331, the first end of the second link 333 is rotatably connected to the second end of the first link 332, the second end of the second link 333 is rotatably connected to the first end of the third link 334, and the second end of the third link 334 is rotatably connected to the screen assembly 322. Of course, in other embodiments, in order to cooperate with other mechanisms to complete the registration printing work, the number of connecting rods can also be adjusted according to specific circumstances.

[0072] Optional, such as Figure 6 As shown, the first mounting bracket 31 includes a first horizontal adjustment portion 311, a second horizontal adjustment portion 312 and a lifting adjustment portion 313, wherein: the second horizontal adjustment portion 312 is connected to the driving end of the first horizontal adjustment portion 311, and the lifting adjustment portion 313 is connected to the driving end of the second horizontal adjustment portion 312. The base plate 321 of the printing mechanism 32 is connected to the driving end of the lifting adjustment portion 313. The first horizontal adjustment portion 311 is used to drive the printing mechanism 32 to move along a first horizontal direction (such as the X-axis direction), the second horizontal adjustment portion 312 is used to drive the printing mechanism 32 to move along a second horizontal direction (such as the Y-axis direction) perpendicular to the first horizontal direction, and the lifting adjustment portion 313 is used to drive the printing mechanism 32 to move up and down.

[0073] Through the cooperation of the first horizontal adjustment part 311 , the second horizontal adjustment part 312 and the lifting adjustment part 313 , the printing mechanism 32 can move freely in the horizontal direction and the vertical direction.

[0074] Optionally, the first horizontal adjustment portion 311 includes a first horizontal mounting plate and a first horizontal driving member, the first horizontal mounting plate is provided with a first guide rail extending along a first horizontal direction (such as an X-axis direction), and the first horizontal driving member is provided on the first horizontal mounting plate.

[0075] The second horizontal adjustment part 312 includes a second horizontal mounting plate and a second horizontal driving member. The second horizontal mounting plate is slidably connected to the first guide rail and is connected to the driving end of the first horizontal driving member. The second horizontal mounting plate is provided with a second guide rail extending along the second horizontal direction. The second horizontal driving member is arranged on the second horizontal mounting plate.

[0076] The lifting adjustment part 313 includes a vertical mounting bracket and a lifting drive member. The vertical mounting bracket is slidably connected to the second guide rail and connected to the driving end of the second horizontal drive member. The vertical mounting bracket is provided with a third guide rail extending in the vertical direction. The lifting drive member is arranged on the vertical mounting bracket.

[0077] The base plate 321 of the printing mechanism 32 is connected to the third guide rail and is connected to the driving end of the lifting driving member.

[0078] When it is necessary to adjust the position of the printing mechanism 32 in the first horizontal direction (such as the X-axis direction), the first horizontal driving member is controlled to drive the second horizontal mounting plate to slide along the first guide rail, thereby driving the lifting and lowering adjustment part 313 and the printing mechanism 32 to move synchronously until the printing mechanism 32 reaches the predetermined position in the first horizontal direction.

[0079] When the position of the printing mechanism 32 in the second horizontal direction (such as the X-axis direction) needs to be adjusted, the second horizontal driving member is controlled to drive the vertical mounting bracket to slide along the second guide rail, thereby driving the printing mechanism 32 to move synchronously until the printing mechanism 32 reaches a predetermined position in the second horizontal direction.

[0080] When the height of the printing mechanism 32 in the vertical direction needs to be adjusted, the lifting drive member is controlled to drive the printing mechanism 32 to rise and fall along the third guide rail until the printing mechanism 32 reaches a predetermined height.

[0081] The first horizontal driving member, the second horizontal driving member and the lifting driving member can all adopt various existing linear driving devices, such as linear driving motors, cylinders, etc.

[0082] Optional, such as Figure 7 As shown, the printing machine 10 includes a turntable 11 and a first printing table 12 connected to the turntable 11. A first loading station A, a first printing station B, and a first unloading station C are sequentially arranged on the rotation path of the turntable 11. Driven by the turntable 11, the first printing table 12 rotates to the first loading station A, the first printing station B, and the first unloading station C in sequence.

[0083] The loading mechanism 20 is disposed at the side of the first loading station A. The loading mechanism 20 loads the battery cells to be printed onto the first printing table 12 which has rotated to the first loading station A.

[0084] The printing device 30 is located above the first printing station B. The scraper assembly 323 of the printing device 30 prints the material on the screen assembly 322 of the printing device 30 onto the battery cell on the first printing table 12 that has rotated to the first printing station B, thereby completing the printing of the battery cell, that is, producing the electrode (gate line / electric field).

[0085] The unloading mechanism 40 is disposed at the side of the first unloading station C. The unloading mechanism 40 receives the printed battery cells from the first printing table 12 rotated to the first unloading station C and outputs the obtained battery cells.

[0086] It can be seen that by setting the printing machine table 10 as a rotary structure, and sequentially arranging the first loading station A, the first printing station B, and the first unloading station C on the rotating path of the turntable 11. As the turntable 11 rotates, the loading mechanism 20, the printing device 30, and the unloading mechanism 40 arranged at the first loading station A, the first printing station B, and the first unloading station C sequentially and continuously implement the loading, printing, and unloading of the battery cells, thereby improving the printing efficiency of the battery cells.

[0087] In order to ensure that the battery cells to be printed outputted from the discharge end of the loading mechanism 20 can be smoothly transferred to the first printing table 12 located at the first loading station A, and to ensure that the printed battery cells on the first printing table 12 located at the first unloading station C can be smoothly transferred to the unloading mechanism 40. Figure 7 As shown, the first printing platform 12 includes a first carrier platform 121 and a cell translation mechanism 122 disposed on the first carrier platform 121. The cell translation mechanism 122 is used to drive the cell carried on the first carrier platform 121 to translate.

[0088] The working process of the cell translation mechanism 122 is as follows:

[0089] Battery cell loading: When the front edge of the battery cell to be printed output by the discharge end of the loading mechanism 20 enters the first supporting platform 121 of the first printing table 12, the corresponding battery cell translation mechanism 122 drives the battery cell to translate away from the discharge end of the loading mechanism 20, so that the battery cell is completely separated from the discharge end of the loading mechanism 20 and is carried onto the first supporting platform 121.

[0090] Battery cell unloading: The battery cell translation mechanism 122 of the first printing table 12 drives the printed battery cells carried on the first supporting platform 121 to translate toward the feeding end of the unloading mechanism 40, so that the battery cells are completely separated from the first supporting platform 121 and enter the feeding end of the unloading mechanism 40.

[0091] It can be seen that by arranging a battery cell translation mechanism 122 on the first printing table 12, the battery cells carried on the first supporting platform 121 are translated and driven, so that the battery cells to be printed outputted from the discharge end of the loading mechanism 20 can be smoothly transferred to the first supporting platform 121 of the first printing table 12, and the printed battery cells on the first supporting platform 121 of the first printing table 12 located at the first unloading station C can be smoothly transferred to the feeding end of the unloading mechanism 40.

[0092] Optionally, the cell translation mechanism 122 includes a first roller, a second roller, a paper roll, and a roller driving mechanism, wherein: the first roller is disposed at a first end of the first carrier 121, and the second roller is disposed at a second end of the first carrier 121 opposite to the first end. The paper roll is tightly placed on the surface of the first carrier 121, one end of the paper roll is wound around the first roller, and the other end of the paper roll is wound around the second roller.

[0093] The table surface of the first supporting platform 121 of the first printing table 12 , the discharging end of the loading mechanism 20 , and the feeding end of the unloading mechanism 40 are located on the same horizontal plane.

[0094] refer to Figure 7 As shown, the working principle of the cell translation mechanism 122 composed of rollers and paper rolls is as follows:

[0095] Cell loading: The first printing table 12 rotates to the first loading station A, at which time the first roller is close to the loading mechanism 20. When the front edge of the cell to be printed outputted from the discharge end of the loading mechanism 20 enters the first loading platform 121 of the first printing table 12, the roller drive mechanism drives the first roller and the second roller to rotate, so as to drive the roll of paper to be wound onto the second roller after being released by the first roller. Driven by the roll of paper, the cell completely leaves the discharge end of the loading mechanism 20 and is completely loaded onto the first loading platform 121.

[0096] For ease of description, we record the paper roll segment that is wound onto the second roller during the loading process as "paper roll segment M", and the paper roll segment that is released from the first roller during the loading process and finally tensioned on the surface of the first carrier 121 as "paper roll segment N". During the cell printing process, the "paper roll segment N" will continue to remain on the surface of the first carrier 121.

[0097] Cell printing: The first printing platform 12 rotates to the first printing station B. After the printing device 30 completes the angle adjustment and height adjustment of the screen assembly 322, the printing operation of the cell is completed.

[0098] Cell unloading: The first printing table 12 rotates to the first unloading station C, at which time the first roller is close to the unloading mechanism 40. The roller drive mechanism drives the first roller and the second roller to rotate, so as to drive the roll paper to be wound onto the first roller after being released by the second roller. Driven by the roll paper, the cell is separated from the first printing table 12 and translated onto the unloading mechanism 40. In this process: the "roll paper segment M" wound onto the second roller during the cell loading process is released again and tensioned on the surface of the first carrier 121, and the "roll paper segment N" tensioned on the surface of the first carrier 121 during the printing process is rewound onto the first roller again.

[0099] At this point, the battery cell translation mechanism 122 completes the current round of battery cell loading and unloading operations.

[0100] During the next round of cell feeding, the “rolled paper segment N” on the outermost layer of the first roller is unrolled from the first roller again and re-tensioned on the surface of the first carrier 121. During the next round of cell printing, the “rolled paper segment N” remains on the surface of the first carrier 121.

[0101] It can be seen that the "roll paper segment N" is repeatedly released and stretched on the first support platform 121, that is, in each round of printing, the "roll paper segment N" is used. In other words, the "roll paper segment N" is contaminated by the printing material each time. In this way, the roll paper is reused and the roll paper cost is reduced.

[0102] Of course, after a certain number of printing times, the printed material accumulated on the "roll paper segment N" reaches an upper limit, that is, the contamination of the "roll paper segment N" exceeds a predetermined value, and it can no longer meet normal use requirements. At this time, it is necessary to completely wind the "roll paper segment N" onto the roller and no longer repeatedly release it. Based on this consideration, optional, such as Figure 7 As shown, a paper receiving station D located between the first unloading station C and the first loading station A is also provided on the rotation path of the turntable 11 .

[0103] The specific process of paper collection is as follows:

[0104] After the battery cells on the first carrier 12 are printed by the printing mechanism at the first printing station B, the contamination degree of the roll paper (ie, "roll paper segment N") stretched on the first carrier is higher than a predetermined value.

[0105] As described above, the highly contaminated “paper roll segment N” is rewound onto the first roller at the first unloading station C, while the uncontaminated “paper roll segment M” is tensioned onto the surface of the first supporting platform 121 .

[0106] Next, the first printing table 12 rotates to the paper receiving station D. At this time, the paper receiving action is performed: the roller drive mechanism drives the first roller and the second roller to rotate, so as to drive the roll paper to be wound onto the first roller after being released by the second roller. That is, the "roll paper segment M" stretched on the table surface of the first bearing table 121 is wound onto the first roller. In other words, the outermost roll paper segment on the first roller is no longer the "roll paper segment N", but the "roll paper segment M".

[0107] Thus, in the next round of battery cell loading, the “roll paper segment M” released from the first roller and tensioned onto the surface of the first carrier 121 is uncontaminated, and the “roll paper segment N” of the previous round will not be released again.

[0108] Continue to refer Figure 7As shown, optionally, the first printing tables 12 are arranged in four groups. Driven by the turntable 11, the four groups of first printing tables 12 rotate to the first loading station A, the first printing station B, the first unloading station C and the paper receiving station D respectively.

[0109] In this way, at the same time, the loading mechanism 20 located on the side of the first loading station A loads the battery cells to be printed onto the first printing table 12 located at the first loading station A, the printing device 30 located above the first printing station B prints the battery cells on the first printing table 12 located at the first printing station B, the unloading mechanism 40 located on the side of the first unloading station C obtains the printed battery cells from the first printing table 12 located at the first unloading station C to realize the unloading of the battery cells, and the first printing table 12 located at the paper receiving station D can implement the paper receiving operation of the contaminated roll paper according to actual conditions.

[0110] like Figure 1 and Figure 2 As shown, optionally, a first detection mechanism 50 is further provided above the feeding mechanism 20, and the first detection mechanism 50 is used to obtain position information of the battery sheet to be printed that is fed to the printing machine table 10. Optionally, the position detection mechanism can be a matrix camera.

[0111] Optionally, the feeding mechanism 20 includes a feeding conveyor belt and a feeding regularization mechanism arranged on both sides of the feeding conveyor belt. When the feeding conveyor belt transports the battery cells to be printed toward the printing machine 10, the feeding regularization mechanism regularizes the battery cells to be printed.

[0112] Optionally, a second detection mechanism 60 is provided above the first unloading station C, and the second detection mechanism is used to detect whether the printed battery cell is qualified. Optionally, the second detection mechanism can be a matrix camera or a PL camera, etc. Of course, the second detection mechanism can also implement a contamination detection of the roll paper stretched on the first printing table 12.

[0113] Second embodiment

[0114] The structure and working principle of the cell printing equipment provided in this embodiment are basically the same as those of the cell printing equipment in the first embodiment mentioned above. For the sake of brevity, this specification only provides a targeted description of the different technical points therein. For the remaining identical technical points, please refer to the relevant description of the first embodiment mentioned above.

[0115] like Figure 8As shown, in the cell printing device of this embodiment, the printing machine 10 includes a second mounting bracket 13 and a second printing table 14 connected to the second mounting bracket 13. The second printing table 14 includes a translation drive mechanism 141, a lifting drive mechanism 142 and a second bearing platform 143. The translation drive mechanism 141 is installed on the second mounting bracket 13, the lifting drive mechanism 142 is connected to the driving end of the translation drive mechanism 141, and the second bearing platform 143 is connected to the driving end of the lifting drive mechanism 142.

[0116] The translation driving mechanism 141 drives the second carrier 143 to translate, and a second loading station E, a second printing station F and a second unloading station G are sequentially arranged on the translation path of the second carrier 143 .

[0117] The loading mechanism 10 is arranged at the side of the second loading station E, and the loading mechanism 10 loads the battery sheet to be printed onto the second loading platform 143 at the second loading station E. Since the structure of the loading mechanism 10 is basically the same as that of the first embodiment, Figure 8 Not shown, please refer to the relevant drawings and description of the first embodiment.

[0118] The printing device 30 is located above the second printing station F, and the scraper assembly 323 of the printing device 30 prints the material on the screen assembly 322 of the printing device 30 onto the battery cell on the second carrier 143 translated to the second printing station F. The specific structure and working process of the printing device 30 have been described in detail in the first embodiment above, and will not be repeated here.

[0119] The unloading mechanism 40 is arranged at the side of the second unloading station G. The unloading mechanism 40 receives the printed battery cells from the second carrier 143 translated to the second unloading station G and outputs the obtained battery cells. Since the structure of the unloading mechanism 40 is basically the same as that of the first embodiment, Figure 8 Not shown, please refer to the relevant drawings and description of the first embodiment.

[0120] It can be seen that by setting the printing machine 10 to include a second printing table that can be translated, and sequentially arranging the second loading station E, the second printing station F, and the second unloading station G on the translation path of the carrier 143 of the second printing table, as the second carrier 143 translates, the loading mechanism 20, the printing device 30, and the unloading mechanism 40 arranged at the second loading station E, the second printing station F, and the second unloading station G sequentially and continuously implement the loading, printing, and unloading of the battery cells, thereby improving the printing efficiency of the battery cells.

[0121] In order to ensure that the battery cells to be printed outputted from the discharge end of the loading mechanism 20 can be smoothly transferred to the second supporting platform 143 of the second printing table 14 located at the second loading station E, and to ensure that the printed battery cells on the second supporting platform 143 of the second printing table 14 located at the second unloading station G can be smoothly transferred to the unloading mechanism 40.

[0122] Optionally, the loading mechanism 20 and the unloading mechanism 40 both include a first conveyor belt and a second conveyor belt arranged side by side for carrying battery cells, and the loading mechanism 20 and the unloading mechanism 40 are located on the same axis.

[0123] Correspondingly, such as Fig. 9 As shown, the second carrier 143 is provided with a first groove 1431 and a second groove 1432 matching the first conveyor belt and the second conveyor belt. Correspondingly, the discharge end of the loading mechanism 20 or the feed end of the unloading mechanism 40 in the second embodiment is configured as two conveyor belts extending outward in the air and parallel to each other.

[0124] When the second carrier 143 needs to receive the battery cells to be printed from the loading mechanism 20, the lifting drive mechanism 142 first drives the second carrier 143 to descend to a low position, and then the translation drive mechanism 141 drives the second carrier 143 to translate to the second loading station E. At this time, the second carrier 143 is located directly below the output end of the loading mechanism 20. Then, the lifting drive mechanism 142 drives the second carrier 143 to rise to a first predetermined height. During this process, the first conveyor belt and the second conveyor belt of the loading mechanism 20 respectively sink into the first groove 1431 and the second groove 1432 on the second carrier 143, and the battery cells to be printed on the loading mechanism 20 are lifted off the loading mechanism 20 by the second carrier 143, that is, the battery cells to be printed are transferred from the loading mechanism 20 to the second carrier 143 of the second printing station 14.

[0125] After the printing of the battery cell is completed, the lifting drive mechanism 142 drives the second carrier 143 to descend and return to its original position, so that the first groove 1431 and the second groove 1432 on the second carrier 143 are at the same height as the first conveyor belt and the second conveyor belt of the unloading mechanism 40. Then, the translation drive mechanism 141 drives the second carrier 143 to translate to the second unloading station G. During this process, the first conveyor belt and the second conveyor belt of the unloading mechanism 40 are respectively inserted into the first groove 1431 and the second groove 1432 on the second carrier 143.

[0126] Next, the lifting drive mechanism 142 drives the second carrier platform 143 to descend to a second predetermined height. During this process, the first conveyor belt and the second conveyor belt of the unloading mechanism 40 float upward out of the first groove 1431 and the second groove 1432 respectively, and the battery cells on the second carrier platform 143 fall onto the first conveyor belt and the second conveyor belt of the unloading mechanism 40, that is, the printed battery cells are transferred from the second carrier platform 143 of the second printing table 14 to the battery cell output mechanism 40.

[0127] Continue to refer Figure 8 As shown, optionally, the second printing table 14 is arranged into four groups, wherein the translation drive mechanism 141 and the lifting drive mechanism 142 of two groups of the second printing table 14 are arranged on the first side wall of the second mounting bracket 13, and the translation drive mechanism 141 and the lifting drive mechanism 142 of the remaining two groups of the second printing table 14 are arranged on the second side wall of the second mounting bracket 13 opposite to the first side wall.

[0128] The four groups of second printing tables 14 alternately receive the battery cells to be printed from the loading mechanism 20 and translate the battery cells to be printed to the second printing station, and place the battery cells on the unloading mechanism 40 after printing, thereby greatly improving the printing efficiency.

[0129] As in the first embodiment, optionally, the cell printing device in this embodiment includes a first detection mechanism disposed above the loading mechanism 20 and a second detection mechanism disposed above the unloading mechanism 40. Details thereof will not be repeated here.
