[0017] In some embodiments, the printing support mechanism includes a translation mechanism, a first printing table and a second printing table; the translation mechanism is used to drive the first printing table to translate between the first loading and unloading station and the printing station, so as to drive the first printing table to obtain a half-cell battery cell group from the first loading and unloading station, and move the half-cell battery cell group to the printing station, and put the printed half-cell battery cell group back to the first loading and unloading station; the translation mechanism is also used to drive the second printing table to translate between the second loading and unloading station and the printing station, so as to drive the second printing table to obtain a half-cell battery cell group from the second loading and unloading station, and move the half-cell battery cell group to the printing station, and put the printed half-cell battery cell group back to the second loading and unloading station.

[0020] By setting the distance between the first printing table and the second printing table, the distance between the first loading and unloading station and the printing station, and the distance between the second loading and unloading station and the printing station to be equal, the translation mechanism only needs to set one driving end to achieve synchronous driving of the first printing table and the second printing table, so as to realize the alternating movement of the first printing table and the second printing table between their respective corresponding loading and unloading stations and printing stations.
[0021] In some embodiments, the first printing table is connected to the first driving end of the translation mechanism, and the second printing table is connected to the second driving end of the translation mechanism; when the first printing table is driven by the first driving end to move to the first loading and unloading station, the second printing table is driven by the second driving end to move to the printing station; when the first printing table is driven by the first driving end to move to the printing station, the second printing table is driven by the second driving end to move to the second loading and unloading station.

[0024] The first printing station and the second printing station are respectively provided with two, and both are driven by independent driving ends, which further speeds up the working rhythm and improves the printing efficiency.
[0025] In some embodiments, a first branch conveyor line is provided with a first avoidance gap for the first printing table to enter and exit at the first loading and unloading station; a second branch conveyor line is provided with a second avoidance gap for the second printing table to enter and exit at the second loading and unloading station; the first printing table and the second printing table have the same structure, and the first printing table includes a carrier table and a paper roll conveying mechanism, wherein: the carrier table is connected to the translation mechanism, and the paper roll conveying mechanism is arranged on the carrier table; when the carrier table enters the first avoidance gap, the paper roll conveying mechanism docks with the first branch conveyor line, and the paper roll conveying mechanism cooperates with the first branch conveyor line to receive the half-cell battery cell group on the first branch conveyor line, or the paper roll conveying mechanism cooperates with the first branch conveyor line to output the half-cell battery cell group that has been printed on the carrier table to the first branch conveyor line, or the paper roll conveying mechanism cooperates with the first branch conveyor line to output the half-cell battery cell group that has been printed on the carrier table to the first branch conveyor line, and at the same time receives the half-cell battery cell group on the first branch conveyor line.
[0026] By setting an avoidance gap on the branch conveyor line and setting a paper roll conveying mechanism on the printing table, the printing table can enter the avoidance gap, thereby achieving docking with the corresponding branch conveyor line. The paper roll conveying mechanism on the printing table cooperates with the branch conveyor line to obtain the half-cell battery group to be printed from the branch conveyor line, or push the half-cell battery group that has been printed to the branch conveyor line. In other words, there is no need to set up an additional handling device to implement the switching of the half-cell battery group between the printing table and the branch conveyor line, thereby reducing equipment costs and avoiding damage to the half-cell battery when the handling device is taking and placing the half-cell battery.

[0049] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0050] The existing cell printing device is only provided with a single printing station, and the printing table moves the cells to be printed one by one along a single conveying path to the printing station for printing. The existing cell printing device is only suitable for printing a whole cell, and it is difficult to meet the printing efficiency of a half cell.
[0051] In view of this, the present application provides a half-cell cell printing device. Figure 1 As shown, the half-cell cell printing device 10 in the embodiment of the present application includes a loading conveyor line 1, a unloading conveyor line 2, a first branch conveyor line 3, a second branch conveyor line 4, a printing mechanism 5 and a printing carrier mechanism 6, wherein:
[0052] The loading conveyor line 1 and the unloading conveyor line 2 are arranged on the first horizontal axis L. At least one printing station A is arranged between the loading conveyor line 1 and the unloading conveyor line 2. Each printing station A is correspondingly provided with a group of printing mechanisms 5 and a group of printing support mechanisms 6.
[0053] The first branch conveyor line 3 is located on the first side (for example, the left side) of the first horizontal axis L, the input end of the first branch conveyor line 3 is connected to the loading conveyor line 1, the output end of the first branch conveyor line 1 is connected to the unloading conveyor line 2, and the first loading and unloading stations B corresponding to the printing stations A are arranged on the conveying path of the first branch conveyor line 3.
[0054] The second branch conveyor line 4 is located on the second side (for example, the right side) of the first horizontal axis L, the input end of the second branch conveyor line 4 is connected to the loading conveyor line 1, and the output end of the second branch conveyor line 4 is connected to the unloading conveyor line 2. The conveying path of the second branch conveyor line 4 is provided with a second loading and unloading station C corresponding to the printing station A. The printing station A and the corresponding first loading and unloading station B and the corresponding second loading and unloading station C are arranged on the second horizontal axis M, and the second horizontal axis M is perpendicular to the first horizontal axis.
[0055] The loading conveyor line 1 is used to convey half-cell battery cell groups 100 along a first horizontal axis L. Each half-cell battery cell group 100 includes two half-cell battery cells perpendicular to the first horizontal axis L and placed side by side.
[0056] The first branch conveyor line 3 and the second branch conveyor line 4 are configured to respectively obtain half-cell battery cell groups 100 from the loading conveyor line 1, and to convey the obtained half-cell battery cell groups 100 to the first loading and unloading station B and the second loading and unloading station C, respectively.
[0057] The printing carrier mechanism 6 is configured to alternately obtain half-cell battery cell groups 100 from the first loading and unloading station B and the second loading and unloading station C, and move the obtained half-cell battery cell groups 100 to the corresponding printing station A, and return the printed half-cell battery cell groups 100 to the first loading and unloading station B and the second loading and unloading station C.
[0058] The printing mechanism 5 is used to print the half-cell battery group 100 located at the printing station A to form gate lines on the two half-cell batteries of the half-cell battery group 100 .
[0059] The first branch conveyor line 3 and the second branch conveyor line 4 are further configured to convey the printed half-cell group 100 to the unloading conveyor line 2 respectively.
[0060] The unloading conveyor line 2 is used to convey the printed half-cell battery cell group 100 to the subsequent workstation.
[0061] The half-cell printing device in the embodiment of the present application, wherein the first branch conveyor line 3 and the second branch conveyor line 4 respectively obtain the half-cell group 100 to be printed from the loading conveyor line 1, and cooperate with the printing carrier mechanism 6 to alternately convey the half-cell group 100 to the printing station A for printing, thereby shortening the waiting time of the printing mechanism 5 and improving the printing efficiency of the half-cell.
[0062] like Figure 2 As shown, optionally, the printing support mechanism 6 includes a translation mechanism 61, a first printing table 62 and a second printing table 63. The translation mechanism 61 is used to drive the first printing table 62 to translate between the first loading and unloading station B and the printing station C, so as to drive the first printing table 62 to obtain the half-cell battery group 100 from the first loading and unloading station B, and move the half-cell battery group 100 to the printing station A, and put the half-cell battery group 100 that has been printed back to the first loading and unloading station B. The translation mechanism 61 is also used to drive the second printing table 63 to translate between the second loading and unloading station C and the printing station A, so as to drive the second printing table 63 to obtain the half-cell battery group 100 from the second loading and unloading station C, and move the half-cell battery group 100 to the printing station A, and put the half-cell battery group 100 that has been printed back to the second loading and unloading station C.
[0063] It can be seen that the first printing table 62 and the second printing table 63 are driven to translate by the translation mechanism 61, so that the first printing table 62 and the second printing table 63 can alternately obtain half-cell battery cell groups 100 from the first loading and unloading station B and the second loading and unloading station C, and move the obtained half-cell battery cell groups 100 to the corresponding printing station A, and return the printed half-cell battery cell groups 100 to the first loading and unloading station B and the second loading and unloading station C.
[0064] Optionally, the first printing table 62 and the second printing table 63 are connected to the same driving end of the translation mechanism 61, and the first printing table 62 and the second printing table 63 are synchronously translated under the drive of the same driving end of the translation mechanism 61. For example, the translation mechanism 61 includes a translation guide rail, a sliding block and a screw drive motor, the translation guide rail is arranged along the second horizontal axis M, the sliding block is slidably connected to the translation guide rail and connected to the driving rod of the screw drive motor, the first printing table 62 and the second printing table 63 are both installed on the sliding block, and the screw drive motor drives the sliding block to translate along the translation guide rail, thereby driving the first printing table 62 and the second printing table 63 to translate synchronously.
[0065] In particular, the distance between the first printing station 62 and the second printing station 63, the distance between the first loading and unloading station B and the printing station A, and the distance between the second loading and unloading station C and the printing station A are equal. Figure 2 As shown in (a) of FIG. 1 , when the first printing table 62 is translated to the first loading and unloading station B, the second printing table 63 is translated to the printing station A synchronously. Figure 2 As shown in (b), when the second printing table 63 is translated to the second loading and unloading station C, the first printing table 62 is synchronously translated to the printing station A. That is, when one of the printing tables is translated to the corresponding loading and unloading station to load and unload the half-cell battery cell group 100, the other printing table carries the half-cell battery cell group 100 and is synchronously translated to the printing station A to receive the printing operation.
[0066] In addition, the translation mechanism 61 only needs to be provided with one driving end to achieve synchronous driving of the first printing table 62 and the second printing table 63, thereby saving driving costs.
[0067] Of course, the translation mechanism 61 may also be provided with two independent driving ends, namely, the first driving end and the second driving end, wherein the first printing table 62 is connected to the first driving end of the translation mechanism 61, and the second printing table 63 is connected to the second driving end of the translation mechanism 61. That is, the first driving end and the second driving end independently drive the first printing table 62 and the second printing table 63 to translate. For example, optionally, the translation mechanism 61 includes a translation guide rail, a first sliding block, a second sliding block, a first screw motor and a second screw motor, the first sliding block and the second sliding block are both slidably connected to the translation guide rail and are respectively connected to the driving rods of the first screw motor and the second screw motor, the first printing table 62 and the second printing table 63 are respectively installed on the first sliding block and the second sliding block, the first screw motor and the second screw motor respectively drive the first sliding block and the second sliding block to translate, thereby respectively driving the first printing table 62 and the second printing table 63 to translate.
[0068] When the first printing table 62 is driven by the first driving end to move to the first loading and unloading station B, the second printing table 63 is driven by the second driving end to move to the printing station A. When the first printing table 62 is driven by the first driving end to move to the printing station A, the second printing table 63 is driven by the second driving end to move to the second loading and unloading station C. In this way, when one of the printing tables is translated to the corresponding loading and unloading station to load and unload the half-cell battery cell group 100, the other printing table carries the half-cell battery cell group 100 and is synchronously translated to the printing station A to receive the printing operation.
[0069] The first printing table 62 and the second printing table 63 are respectively connected to different driving ends of the translation mechanism 61, and independently translate under the drive of their respective driving ends, so there is no need to make any adaptive settings for the distance between the first printing table 62 and the second printing table 63, the distance between the first loading and unloading station B and the printing station A, and the distance between the second loading and unloading station C and the printing station A. In addition, it can ensure that the first printing table 62 is accurately docked with the first branch conveyor line 3, and the second branch conveyor line 4 is accurately docked with the second branch conveyor line 4.
[0070] In order to further improve the printing efficiency, in another optional embodiment, the translation mechanism 61 is provided with four independent driving ends, namely the first driving end, the second driving end, the third driving end and the fourth driving end. Correspondingly, two first printing tables 62 are provided, and the two first printing tables 62 are respectively connected to the first driving end and the second driving end of the translation mechanism 61. Under the independent drive of the first driving end and the second driving end, the two first printing tables 62 alternately obtain the half-cell battery cell group 100 from the first loading and unloading station B, move the half-cell battery cell group 100 to the printing station A, and put the printed half-cell battery cell group 100 back to the first loading and unloading station B. There are also two second printing tables 62, which are respectively connected to the third driving end and the fourth driving end of the translation mechanism 61. The two second printing tables 62 are independently driven by the third driving end and the fourth driving end to alternately obtain the half-cell battery cell group 100 from the second loading and unloading station C, move the half-cell battery cell group 100 to the printing station A, and put the printed half-cell battery cell group 100 back to the second loading and unloading station C.
[0071] Optionally, it can also be arranged as follows: the two first printing tables 62 alternately obtain half-cell battery cell groups 100 from the first loading and unloading station B, move the half-cell battery cell groups 100 to the printing station A, and place the printed half-cell battery cell groups 100 to the second loading and unloading station C; the two second printing tables 62 alternately obtain half-cell battery cell groups 100 from the second loading and unloading station C, move the half-cell battery cell groups 100 to the printing station A, and place the printed half-cell battery cell groups 100 back to the first loading and unloading station B.
[0072] Optionally, the first branch conveyor line 3 is provided with a first avoidance gap for the first printing table 62 to enter and exit at the first loading and unloading station B, and the second branch conveyor line 4 is provided with a second avoidance gap for the second printing table 63 to enter and exit at the second loading and unloading station C.
[0073] The first printing station 62 and the second printing station 63 have the same structure. Taking the first printing station 62 as an example, it includes a supporting platform and a roll paper conveying mechanism, wherein: the supporting platform is connected to the translation mechanism 61, and the roll paper conveying mechanism is arranged on the supporting platform.
[0074] When the carrier enters the first avoidance gap, the paper roll conveying mechanism docks with the first branch conveyor line 3, and the paper roll conveying mechanism cooperates with the first branch conveyor line to convey a half-cell battery group 100 to be printed on the first branch conveyor line 3 to the carrier. Alternatively, the paper roll conveying mechanism cooperates with the first branch conveyor line 3 to output the printed half-cell battery group 100 on the carrier to the first branch conveyor line 3. Alternatively, the paper roll conveying mechanism cooperates with the first branch conveyor line to output the printed half-cell battery group 100 on the carrier to the first branch conveyor line 3, and at the same time, a half-cell battery group 100 to be printed on the first branch conveyor line 3 is conveyed to the carrier.
[0075] It can be seen that by setting an avoidance gap at the loading and unloading stations on the two branch conveyor lines, and respectively setting a paper roll conveying mechanism on the first printing table 62 and the second printing table 63, the first printing table 62 and the second printing table 63 can respectively enter the corresponding avoidance gap, thereby achieving docking with the corresponding branch conveyor line. The paper roll conveying mechanism of the first printing table 62 and the second printing table 63 cooperates with the branch conveyor line to obtain the half-cell battery cell group 100 to be printed from the branch conveyor line, or push the half-cell battery cell group 100 that has been printed to the branch conveyor line. In other words, the switching of the half-cell battery cell group between the printing table and the branch conveyor line can be implemented without the need to set up an additional handling device, thereby reducing the equipment cost and avoiding damage to the half-cell battery cell when the handling device takes and places the half-cell battery cell.
[0076] Still taking the first printing platform 62 as an example, the roll paper conveying mechanism thereon includes a first roll paper roller, a second roll paper roller, a roll paper and a driving mechanism, wherein: the first roll paper roller is arranged at the first end of the carrier platform, and the second roll paper roller is arranged at the second end of the carrier platform, wherein the first end of the carrier platform faces the loading conveyor line 1, and the second end of the carrier platform faces the unloading conveyor line 2. The two ends of the roll paper are respectively wound on the first roll paper roller and the second roll paper roller, and the roll paper is closely attached to the surface of the carrier platform.
[0077] When the carrier platform enters the first avoidance gap, the driving mechanism is configured to drive the second paper roller to reel in the paper, thereby driving the paper to translate from the first end of the carrier platform toward the second end of the carrier platform, so that the half-cell battery cell group 100 to be printed conveyed by the first branch conveyor line 3 enters the carrier platform, or the half-cell battery cell group 100 that has been printed and is located on the carrier platform is output to the first branch conveyor line 3.
[0078] In particular, the driving mechanism is further configured to apply a torque to the first paper winding roller in a direction opposite to the rotation direction of the second paper winding roller, so as to pull the paper in the opposite direction when the second paper winding roller reels the paper, thereby tensioning the paper.
[0079] Optionally, after the roll paper conveying mechanism outputs the printed half-cell battery cell group 100 to the first branch conveyor line 3, the first branch conveyor line 3 temporarily stops conveying the half-cell battery cell group 100 to the roll paper conveying mechanism, and the driving mechanism is also configured to drive the first roll paper roller to reel in the paper, so as to drive the paper to translate from the second end of the support platform toward the first end of the support platform, so that the roll paper of a predetermined length on the second roll paper roller returns to the surface of the support platform again, and the first branch conveyor line 3 starts to convey the half-cell battery cell group 100 to the roll paper conveying mechanism. In this way, the roll paper of a predetermined length can be reused repeatedly until the section of the roll paper can no longer be reused due to excessive contamination. Similarly, during the process of the first roll paper roller reeling in the paper, the driving mechanism is also configured to apply a torque to the second roll paper roller in the opposite direction of the rotation direction of the first roll paper roller to tension the roll paper.
[0080] Alternatively, in order to further improve efficiency, the first branch conveyor line 3 and the roll paper conveyor mechanism are operated simultaneously, so that a group of half-cell battery cell groups 100 to be printed on the first branch conveyor line 3 are moved to the roll paper conveyor mechanism, and at the same time, a group of half-cell battery cell groups 100 that have been printed and are located on the roll paper conveyor mechanism are moved back to the first branch conveyor line 3. Loading and unloading are completed simultaneously, which can significantly improve production efficiency.
[0081] Optionally, the driving mechanism includes a first motor and a second motor, wherein: the first motor is connected to the first paper roll through a first transmission mechanism, the first motor is used to drive the first paper roll to reel in paper through the first transmission mechanism, and is used to apply a torque in the opposite direction of rotation of the second paper roll to the first paper roll when the second paper roll reels in paper. The second motor is connected to the second paper roll through a second transmission mechanism, the second motor is used to drive the second paper roll to reel in paper through the second transmission mechanism, and is used to apply a torque in the opposite direction of rotation of the first paper roll to the second paper roll when the first paper roll reels in paper.
[0082] The first motor and the second motor independently drive the first paper roller and the second paper roller to rotate, so that when one of the first paper roller and the second paper roller reels the paper, the other of the first paper roller and the second paper roller can pull the paper in the opposite direction, thereby ensuring that the paper remains in a tensioned state.
[0083] Continue to refer Figure 1 As shown, optionally, in the half-cell printing mechanism in the embodiment of the present application, there are two first loading and unloading stations B and two second loading and unloading stations C. Correspondingly, there are two printing stations A, wherein the second printing station is located after the first printing station, and the first printing station prints the first half-cell of the obtained half-cell group 100, and the second printing station prints the unprinted second half-cell of the obtained half-cell group. Such a setting can further speed up the work rhythm and improve printing efficiency.
[0084] The present application also provides a half-cell cell printing device, such as Figure 2 As shown, the half-cell printing device includes two sets of half-cell printing devices 10 provided by any of the above embodiments arranged in parallel. The two sets of half-cell printing devices 10 implement half-cell printing in parallel, ensuring the printing efficiency of the half-cell printing device.

It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application.
