[0029] The positioning of the half-cell battery group to be printed is achieved, so that the printing screen of the first printing mechanism can be aligned with the half-cell battery group to be printed, ultimately ensuring printing accuracy.

[0031] By configuring the second printing line to include a feeder branch line, a second printing station, a second printing mechanism, and a second transition conveyor line, the second printing line receives half-cell stacks distributed by the feeder mechanism, prints on these stacks, and then transfers the printed half-cell stacks to the unloading mechanism. Furthermore, a second positioning mechanism positions the half-cell stack to be printed, allowing the second printing mechanism's printing screen to align with the half-cell stack to be printed, ultimately ensuring printing accuracy.
[0032] In some embodiments, the second printing table includes a second translation mechanism, a second supporting platform and a second paper roll conveying mechanism, wherein: the second supporting platform is connected to the driving end of the second translation mechanism, and the second paper roll conveying mechanism is arranged on the second supporting platform; the second translation mechanism is used to drive the second supporting platform to translate between the output end of the loading branch line and the second printing station; when the second supporting platform moves to the output end of the loading branch line, the second paper roll conveying mechanism docks with the output end of the loading branch line, and the second paper roll conveying mechanism cooperates with the loading branch line to receive the half-cell battery cell group output by the loading branch line; when the second supporting platform moves to the second printing station, the second paper roll conveying mechanism docks with the input end of the second transition conveyor line, and the second paper roll conveying mechanism cooperates with the second transition conveyor line to output the printed half-cell battery cell group to the second transition conveyor line.

[0052] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0053] Existing cell printing devices only have a single printing station, where the printing table moves the cells to be printed one by one to the printing station for printing. Existing cell printing devices are only suitable for printing full cells and are unable to meet the printing efficiency requirements for half cells.
[0054] In view of this, the embodiment of the present application provides a half-cell printing device. Figure 1 As shown, the half-cell printing device in the embodiment of the present application includes a loading conveyor line 1, a material separation mechanism 2, a first printing line 3, at least one second printing line 4 and a material unloading mechanism 5, wherein:
[0055] The loading conveyor line 1 is used to convey half-cell battery cell groups 100 along a first horizontal direction (such as the X-axis direction in the figure). Each half-cell battery cell group 100 includes two half-cell battery cells placed side by side along a second horizontal direction. A material separation station A is provided on the conveying path of the loading conveyor line 1, wherein the second horizontal direction is perpendicular to the first horizontal direction.
[0056] The input end of the first printing line 3 is configured to be connected to the output end of the loading conveyor line 1 . The loading conveyor line 3 is used to output the half-cell battery cell group 100 to the first printing line 1 .
[0057] The sorting mechanism 2 is arranged between the sorting station A and the input end of the second printing line 4 . The sorting mechanism 2 is used to pick up half-cell battery cell groups 100 from the loading conveyor line 1 and transfer the picked up half-cell battery cell groups 100 to the second printing line 4 .
[0058] The first printing line 3 has a first printing station B. The first printing line 3 is used to convey the half-cell battery cell group 100 output by the feeding conveyor line 1 to the first printing station B for printing.
[0059] The second printing line 4 has a second printing station C. The second printing line 4 is used to transport the half-cell battery cell group 100 transferred by the material dividing mechanism 2 to the second printing station C for printing.
[0060] The unloading mechanism 5 is arranged at the output end of the first printing line 3 and the output end of the second printing line 4. The unloading mechanism 5 is used to receive the printed half-cell battery group 100 output by the first printing line 3 and the second printing line 4, and to transport the printed half-cell battery group 100 to the downstream workstation.
[0061] In the half-cell printing device of the embodiment of the present application, the first printing line 3 and the second printing line 4 respectively obtain the half-cell group 100 to be printed from the loading conveyor line 1, and after completing the printing of the half-cell group 100, the printed half-cell group 100 is conveyed to the unloading mechanism 5, and the unloading mechanism 5 conveys the printed half-cell group 100 to the subsequent workstation. Since the first printing line 3 and the second printing line 4 can print the half-cell group 100 including two half-cell cells in parallel, the present application greatly improves the printing efficiency of half-cell cells.
[0062] The printing involved in this application refers to printing a conductive adhesive area on the edge of a half-cell battery cell by screen printing or inkjet printing, or printing a metal grid line on the surface of a half-cell battery cell. The printing paste used is generally a silver or aluminum-containing screen printing paste, conductive glue, etc.
[0063] like Figure 1As shown, the first printing line 3 optionally includes at least one first printing station 31, a first printing mechanism 32, and a first transition conveyor line 33. The first printing station 31 is configured to translate between the output end of the loading conveyor line 1 and the first printing station B to receive the half-cell battery cell group 100 output by the loading conveyor line 1 and convey the half-cell battery cell group 100 to the first printing station B. The first printing mechanism 32 is disposed above the first printing station B and is configured to print the half-cell battery cell group 100 located at the first printing station B. The input end of the first transition conveyor line 33 is adjacent to the first printing station B, and the output end of the first transition conveyor line 33 interfaces with the unloading mechanism 5. The first transition conveyor line 33 is configured to receive the printed half-cell battery cell group output by the first printing station 32 and convey the printed half-cell battery cell group to the unloading mechanism 5.
[0064] As can be seen, through the coordination of the first printing station 31, the first printing mechanism 32, and the first transition conveyor line 33, the first printing line 3 obtains the half-cell battery group 100 to be printed from the loading conveyor line 1, completes printing on the half-cell battery group 100, and then automatically conveys the printed half-cell battery group 100 to the unloading mechanism 5. To further improve printing efficiency, at least two groups of first printing stations 31 are provided. At least two groups of first printing stations 31 alternately obtain half-cell battery groups 100 from the loading conveyor line 1, convey the half-cell battery groups 100 to the first printing station B, and convey the printed half-cell battery group 100 to the unloading mechanism 5.
[0065] When at least two sets of first printing tables 31 are provided, each set of first printing tables 31 can optionally be mounted to the drive ends of two lifting modules, which are then mounted to two transverse modules on either side of the platform. Each set of first printing tables 31 can move laterally along the platform. Taking the first printing line 3 as an example, each set of first printing tables 31 can move back and forth between the first positioning station D and the first printing station B. Furthermore, because the first printing tables 31 can be driven up and down, the two sets of first printing tables 31 can avoid each other at different heights, alternating and cyclically transporting half-cell stacks 100 from the first positioning station D to the first printing station B for loading, printing, and unloading.
[0066] Alternatively, the first printing station 31 includes a first translation mechanism, a first support platform, and a first paper roll conveying mechanism, wherein the first support platform is connected to the driving end of the first translation mechanism, and the first paper roll conveying mechanism is disposed on the first support platform. The first translation mechanism is used to drive the first support platform to translate between the output end of the loading conveyor line 1 and the first printing station B. When the first support platform moves to the output end of the loading conveyor line 1, the first paper roll conveying mechanism docks with the output end of the loading conveyor line 1 and cooperates with the loading conveyor line to receive the half-cell battery cell group output by the loading conveyor line 1. When the first support platform moves to the first printing station B, the first paper roll conveying mechanism docks with the input end of the first transition conveyor line 33. After the first printing mechanism 32 completes printing on the half-cell battery cell group, the first paper roll conveying mechanism cooperates with the first transition conveyor line 33 to output the printed half-cell battery cell group to the first transition conveyor line 33.
[0067] As can be seen, by driving the first carrier platform to translate through the first translation mechanism, the first carrier platform achieves translational switching between the output end of the loading conveyor line 1 and the first printing station B. Furthermore, by providing a first roll paper conveying mechanism on the first carrier platform, the first carrier platform can automatically obtain the half-cell battery cell group output by the loading conveyor line 1 when docking with the output end of the loading conveyor line 1, and can automatically push the printed half-cell battery cell group onto the first transition conveyor line 33 when docking with the input end of the first transition conveyor line 33. In other words, the first roll paper conveying mechanism achieves the transfer of the half-cell battery cell group. This embodiment of the present application eliminates the need for an additional handling device to carry out the handling of the half-cell battery cell group, thus preventing the handling device from damaging the half-cell battery cell during handling.
[0068] In an optional printing implementation, the first paper roll conveyor mechanism is provided as a set, and both half-cells in the half-cell group 100 are positioned on the first paper roll conveyor mechanism. The first printing mechanism 32 includes a printing screen having a printing area corresponding to one half-cell. That is, the printing screen can only be aligned with one half-cell at a time and print on one half-cell.
[0069] The first printing station also includes a first UVW module that is transmission-connected to the first paper roll conveying mechanism.
[0070] When the first carrier translates to the first printing station B (or during translation), the first UVW module adjusts the position and angle of the first paper roll conveyor mechanism so that one of the half-cell cells in the half-cell group is aligned with the printing area of the printing screen, and the printing screen first completes printing on this half-cell cell. Then, the first UVW module again adjusts the position and angle of the first paper roll conveyor mechanism so that the other half-cell cell in the half-cell group is aligned with the printing area, and the printing screen completes printing on the other half-cell cell.
[0071] Of course, the position and angle of the screen can also be adjusted. Specifically, the first printing mechanism 32 also includes a second UVW module that is transmission-connected to the printing screen. When the first carrier platform is translated to the first printing station B, the second UVW module adjusts the position and angle of the printing screen so that the printing area is aligned with one of the half-cells in the half-cell group, and the printing screen first completes the printing of the half-cell. Then, the second UVW module adjusts the position and angle of the printing screen again so that the printing area is aligned with the other half-cell in the half-cell group, and the printing screen completes the printing of the other half-cell.
[0072] The first printing mechanism 32 prints the two half-cells in the half-cell group twice. Before each printing, the position and angle of the half-cell to be printed are adjusted to ensure that the printing area of the screen is aligned with the half-cell to be printed, thereby ensuring printing accuracy.
[0073] In another optional printing implementation, the first paper roll conveying mechanism is provided as two groups arranged side by side, and the two half-cell battery cells in the half-cell group 100 are respectively located on one group of the first paper roll conveying mechanism.
[0074] The first printing mechanism 32 includes a printing screen having two printing areas corresponding to the two half-cell cells in the half-cell group 100. That is, the printing screen can be aligned with the two half-cell cells in the half-cell group 100 each time and can print on the two half-cell cells simultaneously.
[0075] The first printing station further includes a third UVW module that is transmission-connected to one group of first paper roll conveying mechanisms, and a fourth UVW module that is transmission-connected to another group of first paper roll conveying mechanisms.
[0076] When the first carrier platform is translated to the first printing station B, the third UVW module adjusts the position and angle of one group of first paper roll conveying mechanisms, and the fourth UVW module adjusts the position and angle of another group of first paper roll conveying mechanisms, so that the two half-cell cells in the half-cell group 100 are aligned with the corresponding printing areas on the printing screen, and the printing screen prints the two half-cell cells at the same time.
[0077] Of course, the position and angle of the screen can also be adjusted. Specifically, the first printing mechanism 32 also includes a fifth UVW module in transmission connection with the printing screen. When the first carrier translates to the first printing station B, the fifth UVW module adjusts the position and angle of the printing screen so that the two printing areas are aligned with one cell in the half-cell group 100, and the printing screen prints on both half-cells simultaneously.
[0078] The first printing mechanism simultaneously prints both half-cells in the half-cell assembly 100, further improving printing efficiency. Before printing, the position and angle of the screen or the two half-cells to be printed are adjusted to ensure that the two printing areas of the screen are aligned with the two half-cells to be printed, thereby ensuring printing accuracy.
[0079] The first, second, third, fourth, and fifth UVW modules used in the embodiments of the present application can all be various types of existing UVW modules. The UVW modules can drive the target to translate and rotate horizontally, and may include a mechanism for driving the target to rise and fall vertically, thereby adjusting the position and angle of the target.
[0080] Optionally, the first paper roll conveying mechanism includes a first paper roll roller, a second paper roll roller, a first paper roll and a first driving mechanism, wherein: the first paper roll roller is arranged at the first end of the first supporting platform, and the second paper roll roller is arranged at the second end of the first supporting platform, wherein the first end of the first supporting platform is close to the output end of the loading conveyor line, and the second end of the first supporting platform is close to the input end of the first transition conveyor line; the two ends of the first paper roll are respectively wound on the first paper roll roller and the second paper roll roller, and the first paper roll is tightly attached to the table surface of the first supporting platform.
[0081] When the first paper roll conveyor mechanism docks with the output end of the loading conveyor line 1 or the input end of the first transition conveyor line 33, the first drive mechanism is configured to drive the second paper roll roller to reel in the first paper roll, thereby driving the first paper roll to translate from the first end of the first carrier platform toward the second end of the first carrier platform, so that the half-cell battery cell group output from the loading conveyor line 1 enters the first carrier platform. Alternatively, the printed half-cell battery cell group located on the first carrier platform is output to the first transition conveyor line 33.
[0082] In particular, the first driving mechanism is further configured to apply a torque to the first paper roll in a direction opposite to the rotation direction of the second paper roll, so as to pull the first paper roll in the opposite direction when the second paper roll reels the first paper roll, thereby tensioning the first paper roll.
[0083] Optionally, after the first paper roll conveying mechanism outputs the printed half-cell battery cell group 100 to the first transition conveyor line 33. The first drive mechanism is also configured to drive the first paper roll roller to reel in the first paper roll, so as to drive the first paper roll to translate from the second end of the first supporting platform toward the first end of the first supporting platform, so that the first paper roll of a predetermined length on the second paper roll roller returns to the table surface of the first supporting platform. In this way, the paper roll of a predetermined length can be reused until the section of paper roll can no longer be reused due to excessive contamination. Similarly, during the process of reeling in the first paper roll, the first drive mechanism is also configured to apply a torque to the second paper roll roller in the opposite direction of rotation of the first paper roll roller to tension the first paper roll.
[0084] Optionally, the first drive mechanism includes a first motor and a second motor, wherein: the first motor is connected to the first paper roll via a first transmission mechanism, the first motor is used to drive the first paper roll via the first transmission mechanism to reel in the first paper roll, and is used to apply a torque to the first paper roll in a direction opposite to the rotation direction of the second paper roll when the second paper roll reels reel in the first paper roll. The second motor is connected to the second paper roll via a second transmission mechanism, the second motor is used to drive the second paper roll via the second transmission mechanism to reel in the first paper roll, and is used to apply a torque to the second paper roll in a direction opposite to the rotation direction of the first paper roll when the first paper roll reels reel in the first paper roll.
[0085] The first motor and the second motor independently drive the first paper winding roller and the second paper winding roller to rotate, so that when one of the first paper winding roller and the second paper winding roller rewinds the first paper roll, the other of the first paper winding roller and the second paper winding roller can pull the first paper roll in the opposite direction, thereby ensuring that the first paper roll remains in a tensioned state.
[0086] Continue to refer Figure 1 As shown, a first positioning station D is optionally provided at the output end of the loading conveyor line 1. The first printing line 3 also includes a first positioning mechanism disposed above the first positioning station D. The first positioning mechanism is used to position the half-cell battery pack that has entered the first loading platform to obtain the position information of the half-cell battery pack. This ensures that the printing screen of the first printing mechanism is aligned with the half-cell battery pack 100 to be printed, ultimately ensuring printing accuracy.
[0087] Continue to refer Figure 1As shown, the second printing line 4 optionally includes a feeding branch line 41, a second printing table 42, a second printing mechanism 43, and a second transition conveyor line 44. The input end of the feeding branch line 41 is adjacent to the feeder mechanism 2, which transfers the picked-up half-cell battery cell group 100 to the feeding branch line 41. The second printing table 42 is configured to translate between the output end of the feeding branch line 41 and the second printing station C to receive the half-cell battery cell group 100 output by the feeding branch line 41 and to convey the half-cell battery cell group 100 to the second printing station C. The second printing mechanism 43 is disposed above the second printing station C and is configured to print the half-cell battery cell group 100 located at the second printing station C. The input end of the second transition conveyor line 44 is adjacent to the second printing station C, and the output end of the second transition conveyor line 44 is connected to the unloading mechanism 5. The second transition conveyor line 44 is used to receive the printed half-cell group 100 output by the second printing station 42 and convey the printed half-cell group 100 to the unloading mechanism 5 .
[0088] It can be seen that, through the coordination of the feeding branch line 41, the second printing station 42, the second printing mechanism 43, and the second transition conveyor line 44, the second printing line 4 obtains the half-cell battery group 100 to be printed from the feeder mechanism 2, completes the printing on the half-cell battery group 100, and then automatically conveys the printed half-cell battery group 100 to the unloading mechanism 5. Of course, in order to further improve printing efficiency, the second printing stations 42 can also be provided in at least two groups, with at least two groups of second printing stations 42 alternately obtaining the half-cell battery group 100 from the feeder mechanism 2, conveying the half-cell battery group 100 to the second printing station C, and conveying the printed half-cell battery group 100 to the unloading mechanism 5.
[0089] Optionally, a second positioning station E is provided at the output end of the feeding branch line 41. The feeding branch line 41 also includes a second positioning mechanism disposed above the second positioning station E. The second positioning mechanism is used to position the half-cell group entering the second printing table to obtain the position information of the half-cell group. This ensures that the printing screen of the second printing mechanism 43 is aligned with the half-cell group 100 to be printed, ultimately ensuring printing accuracy.
[0090] Optionally, the second printing station includes a second translation mechanism, a second supporting platform, and a second paper roll conveying mechanism, wherein: the second supporting platform is connected to the driving end of the second translation mechanism, and the second paper roll conveying mechanism is arranged on the second supporting platform. The second translation mechanism is used to drive the second supporting platform to translate between the output end of the loading branch line 41 and the second printing station C. When the second supporting platform moves to the output end of the loading branch line 41, the second paper roll conveying mechanism docks with the output end of the loading branch line 41, and the second paper roll conveying mechanism cooperates with the loading branch line 41 to receive the half-cell battery cell group output by the loading branch line 41. When the second supporting platform moves to the second printing station C, the second paper roll conveying mechanism docks with the input end of the second transition conveyor line 44, and the second paper roll conveying mechanism cooperates with the second transition conveyor line 44 to output the printed half-cell battery cell group to the second transition conveyor line 44.
[0091] As can be seen, the second translation mechanism drives the second carrier to translate, enabling the second carrier to translate and switch between the output end of the feeding branch line 41 and the second printing station C. Furthermore, by providing a second paper roll conveying mechanism on the second carrier, the second carrier can automatically receive the half-cell battery cell group output by the feeding branch line 41 when docking with the output end of the feeding branch line 41, and automatically push the printed half-cell battery cell group onto the second transition conveyor line 44 when docking with the input end of the second transition conveyor line 44. In other words, the second paper roll conveying mechanism enables the transfer of half-cell battery cell groups. This embodiment of the present application eliminates the need for an additional handling device to handle the half-cell battery cell groups, thus preventing the handling device from damaging the half-cell battery cells during transport.
[0092] The two optional printing methods for the first printing line 3 described in the previous embodiments are also applicable to the second printing line 4. That is, by configuring the second printing table and the second printing mechanism 43, the second printing mechanism 43 can print the two half-cells in the half-cell group separately in two steps. Before each printing, the position and angle of the half-cell to be printed are adjusted to ensure that the printing area of the screen is aligned with the half-cell to be printed, thereby ensuring printing accuracy.
[0093] By setting up the second printing table and the second printing mechanism 43, the second printing mechanism 43 can also simultaneously print two half-cell batteries in the half-cell battery group 100. Before printing, the position and angle of the screen or the two half-cell batteries to be printed are adjusted to ensure that the two printing areas of the screen are aligned with the two half-cell batteries to be printed, thereby ensuring printing accuracy.
[0094] like Figure 1 and Figure 2As shown, optionally, the half-cell printing device in the embodiment of the present application includes two second printing lines 4 arranged side by side. The material distribution mechanism 2 includes a translation module 21 and two sets of suction cup assemblies 22 corresponding one to one with the second printing lines 4. The suction cup assemblies 22 are connected to the driving end of the translation module 21. The translation module 21 is used to drive the suction cup assemblies 22 to translate between the loading conveyor line 1 and the corresponding second printing line 4, so as to drive the suction cup assemblies 22 to pick up the half-cell battery group 100 from the loading conveyor line 1 and transfer the picked up half-cell battery group 100 to the second printing line 4.
[0095] The two second printing lines 4 arranged side by side perform printing on the half-cell battery pack 100 in parallel, further improving the printing efficiency. Of course, a third or more second printing lines 4 can also be provided.
[0096] Continue to refer Figure 1 As shown, the unloading mechanism 5 optionally includes a collection mechanism 51 and a unloading conveyor line 52. The collection mechanism 51 interfaces with the output terminals of the first printing line 3 and each of the second printing lines 4. The collection mechanism 51 is used to pick up the printed half-cell battery packs 100 output by the first printing line 3 and each of the second printing lines 4 and transfer the picked-up printed half-cell battery packs 100 to the unloading conveyor line 52. The unloading conveyor line 52 is used to transport the printed half-cell battery packs to a downstream station.
[0097] Alternatively, the input end of the unloading conveyor line 52 is connected to the output end of one of the first printing line 3 and each of the second printing lines 4. The confluence mechanism 51 is connected to the output ends of the remaining first printing lines 3 and each of the second printing lines 4. The unloading conveyor line 52 is used to receive the printed half-cell battery cell groups 100 output by the first printing line 3 and each of the second printing lines connected to it. The confluence mechanism 51 is used to pick up the printed half-cell battery cell groups 100 output by the remaining first printing lines 3 and each of the second printing lines 4, and transfer the picked up printed half-cell battery cell groups 100 to the unloading conveyor line 52. The unloading conveyor line 52 is used to transport the printed half-cell battery cell groups 100 to the downstream workstation.
[0098] It can be seen that through the cooperation of the converging mechanism 51 and the unloading conveyor line 52, the unloading mechanism 5 realizes the converging of the printed half-cell group 100 output by the first printing line 3 and each second printing line 4, and conveys the printed half-cell group 100 to the subsequent workstation.
