[0041] Example:

[0042] See also Figures 1 to 5 In a preferred embodiment of the utility model, a transmission device is provided, which includes an interactive transmission device 1, and the interactive transmission device 1 includes a base 11, a transverse movement device 12 arranged on the side of the base 11, and a lifting device 13 arranged on the transverse movement device 12, and a bearing platform 14 is arranged on the lifting device 13. The transverse movement device 12 reciprocates in the horizontal direction, which is defined as the first direction in this embodiment; the lifting device 13 lifts and lowers in the vertical direction. In this embodiment, the transverse movement device 12 is a linear motor, whose stator is arranged along the first direction, and the mover reciprocates in the first direction. The lifting device 13 is a motor screw module, which drives the bearing platform 14 to rise and fall in the vertical direction.

[0043] For details, see Figure 1 and Figure 2 . Figure 1 Schematic diagram of the transmission device. Figure 2It is a schematic diagram of the front view of the interactive transmission device. In the horizontal plane, the second direction is defined as perpendicular to the first direction. As a form of the interactive transmission device 1, the transverse movement device 12 includes two on both sides of the second direction of the base 11, namely, a first transverse movement device 1201 and a second transverse movement device, and a first lifting device 1301 and a second lifting device respectively arranged thereon, and a first load platform 1401 and a second load platform 1402 respectively arranged thereon. In this way, the first load platform 1401 and the second load platform 1402 can be transmitted in the first direction and the vertical direction respectively, and when crossing in the horizontal direction, the lifting modules are stacked in the vertical direction to avoid collision, thereby realizing interactive transmission of the load platforms.

[0044] Furthermore, the transmission device further comprises a loading and unloading conveyor belt module arranged in front of or behind the interactive transmission device 1 along the first direction. And a transfer module 2 arranged between the interactive transmission device 1 and the loading and unloading conveyor belt module. Figure 1 , Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of the transfer fork module. Figure 5 for Figure 4 A partially enlarged view. Specifically, the transfer module 2 includes a seat body 21, a transverse moving module 22 arranged on the side of the seat body 21 in the second direction, and a lifting module arranged on the transverse moving module 22, and a transfer fork module 24 is arranged on the lifting module. The transverse moving module 22 drives the transfer fork module 24 to reciprocate in the first direction; the lifting module drives the transfer fork module 24 to lift and lower in the vertical direction. In this embodiment, the transverse moving module is a linear motor, whose stator is arranged along the first direction, and the mover reciprocates in the first direction. The lifting module is a motor screw module, which drives the transfer fork module 24 to lift and lower in the vertical direction. In this way, the transfer fork module 24 can move the transverse moving module 22 and the lifting module in the first direction and the vertical direction to reach the loading and unloading conveyor belt module and the interactive transmission device 1.

[0045] As a specific implementation, the loading conveyor belt module 3, the interactive transmission device 1, and the unloading conveyor belt module 4 are arranged sequentially in the first direction, and a transfer module 2 is arranged between the loading conveyor belt module 3 and the interactive transmission device 1, and between the interactive transmission device 1 and the unloading conveyor belt module 4.

[0046] Specifically, the loading conveyor belt module 3 transfers the material to its discharge end, and the transfer fork module 24 of the transfer module 2 arranged between the loading conveyor belt module 3 and the interactive transmission device 1 reaches the discharge end of the loading conveyor belt module 3 driven by the transverse movement module 22. At this time, the bearing surface of the transfer fork module 24 is located below the transmission surface of the loading conveyor belt module 31, that is, below the material, and the lifting module drives the transfer fork module 24 to rise, and the material is separated from the loading conveyor belt module 3 and lifted by the transfer fork module 24, and then driven by the transverse movement module 22 to move to the loading end of the interactive transmission device 1. At this time, the bearing surface of the load-bearing platform 14 is located below the transfer fork module 24, which rises under the drive of the lifting device 13, and the material is separated from the transfer fork module 24 and transferred to the load-bearing platform 14. The load-bearing platform 14 is driven by the transverse movement device 12 to move transversely along the first direction to the discharge end of the interactive transmission device 1. At this time, the transfer fork module 24 of the transfer module 2 disposed between the interactive transmission device 1 and the unloading conveyor belt module 4 is located below the carrier platform 14 at the unloading end, the carrier platform 14 is driven down by the lifting device 13, the material is separated from the carrier platform 14, and is transferred to the transfer fork module 24, the transfer fork module 24 is driven by the transverse module 22, and is transversely moved along the first direction to the feeding end of the unloading conveyor belt module 4, and is driven by the lifting module to descend to a transmission surface lower than the unloading conveyor belt module 4, the material is separated from the transfer fork module 24, and is transferred to the unloading conveyor belt module 4. It can be understood that at this time, once the material on the carrier platform 14 at the unloading end is transferred, the carrier platform 14 can be driven by the transverse device 12 to move transversely to the loading end for the next loading.

[0047] As mentioned above, the traverse device 12 and the lifting device 13 include two on both sides of the second direction of the base 11, and the two have the same movement mode and are performed alternately. It can be understood that when the first traverse device 1201 and the first lifting device 1301 drive their bearing platform 14 to transfer materials along the first direction, the second traverse device and the second lifting device drive their bearing platform 14 to return to the loading end in the reverse direction along the first direction, and the two interact to complete the material transmission.

[0048] See also Figures 1 to 5 The transfer fork module 24 includes strip-shaped support members 241 arranged on both sides of the seat body 21 in the second direction and extending inward to support the material. Figure 3 , is a structural schematic diagram of the carrying platform, the carrying platform 14 is correspondingly provided with avoidance grooves 141, specifically, strip avoidance grooves 141 extending along the second direction are provided on both sides of the second direction of the surface of the carrying platform 14, when the interactive transmission device 1 and the transfer module 2 transfer materials, the carrying platform 14 and the transfer fork module 24 correspond to each other in the horizontal direction, when the carrying platform 14 is raised or lowered, the strip support member 241 can pass through the avoidance grooves 141, thereby realizing the transfer of materials between the transfer fork module 24 and the carrying platform 14.

[0049] As a preferred embodiment, the strip support members 241 include a plurality of groups spaced apart along the first direction, such as Figure 4 The two groups shown, i.e., two arranged in the first direction and two symmetrically arranged in the second direction, four strip-shaped support members 241 can achieve good support for the material.

[0050] In order to further achieve a good supporting effect, an adsorption chamber (not shown in the figure) is provided inside the strip support 241, which is connected to a negative pressure generating device. A second adsorption hole 242 is provided on the upper surface of the strip support 241 to achieve fixed support for the material through negative pressure adsorption to prevent the device from shifting during lateral movement or lifting.

[0051] Correspondingly, the avoidance grooves 141 of the carrying platform 14 also include a plurality of avoidance grooves 141 arranged at intervals along the first direction, such as Figure 2 As shown in FIG. 2 , two avoidance grooves 141 are provided in the first direction, and two are symmetrically provided in the second direction.

[0052] Those skilled in the art can understand that the number of strip support members corresponds to the number of avoidance grooves, the distance between adjacent strip support members is equal to the distance between adjacent avoidance grooves, and the width of the strip support member is not greater than the width of the avoidance grooves.

[0053] It can be understood by those skilled in the art that the length of the avoidance groove should not be too long. As a preferred solution, the length of the avoidance groove is preferably not more than 25% of the width of the carrier. This is superior to the prior art, which can only print along the direction of the avoidance groove during screen printing. The present application adopts the above-mentioned setting, and the avoidance groove 141 on the carrier 14 has a short extension length on the carrier. When screen printing is performed, the scraper can scrape the material along the first direction or the second direction.

[0054] Further preferably, an adsorption chamber (not shown in the figure) is provided inside the carrier 14 and connected to a negative pressure generating device, and adsorption holes 142 are provided on the upper surface of the carrier, so that the material can be well fixed on the carrier by negative pressure adsorption to avoid displacement during the moving process, and at the same time, it is also conducive to achieving good fixation during screen printing to ensure printing accuracy. Preferably, adsorption holes 142 are provided on both sides of the avoidance groove 141 for a good fixing effect.

[0055] In order to realize the transmission of materials and to fix them well on the carrier 14 so as to complete the printing operation on the carrier, in the transmission device of the present application, the width of the loading conveyor belt module 3 and the unloading conveyor belt module 4 is smaller than the width of the material to be transmitted, and the distance in the second direction between the two strip supports 241 of the transfer fork module 24 is larger than the width of the loading conveyor belt module 3 and the unloading conveyor belt module 4, and smaller than the width of the material, so that the material can be lifted from both sides. The width of the carrier 14 is larger than the width of the material, so that all the materials can be placed on the carrier. It should be noted that the width of the loading conveyor belt module 3 and the unloading conveyor belt module 4 refers to the width of the conveyor belt. When there are multiple parallel conveyor belts, it refers to the width of the edge of the conveyor belt. The width of the carrier 14 refers to the dimension along the second direction.

[0056] As a more preferred embodiment, the utility model provides an interactive transmission device, wherein the first transverse moving device 1201 and the second transverse moving device may include a plurality of movers, such as Figure 1 , Figure 2 As shown, each includes two movers, and a bearing platform 14 is arranged on each mover to increase the production capacity. Correspondingly, the transfer fork module 24 includes a plurality of transfer fork modules arranged along the first direction.

[0057] like Figure 4 As shown, in order to facilitate fixing and provide negative pressure, the transfer fork module 24 includes a support seat 243, which is arranged on both sides of the seat body 21, a support rod 244, which is fixed on the support seat 243, and a strip support member 241 is fixed on the support rod 244 through a connecting member 245. More specifically, the seat body 21 is arranged below the loading conveyor belt module 3 or the unloading conveyor belt module 4, and the support rod 244 extends toward the interactive transmission device 1, so that the seat body 21 and the base 11 do not interfere with each other, and the transverse movement device 12 and the transverse movement module 22 do not interfere with each other, but the transfer fork module 24 can be moved to the loading conveyor belt module 3 or the unloading conveyor belt module 4 and the interactive transmission device 1.

[0058] See also Figure 6On the other hand, the utility model also provides a printing device, including the aforementioned transmission device, and also including a printing module 5 arranged above the interactive transmission device 1. Specifically, the printing module 5 is arranged on the transverse movement route of the carrier 14. The printing module 5 can be a printing module of the prior art, and more specifically, includes a screen printing screen, a scraper, a Z-axis module that drives the screen printing screen to move in the vertical direction, a mobile module that moves in the horizontal plane, and a scraper driving assembly that drives the scraper to rise and fall in the vertical direction and move in the horizontal direction. When the carrier 14 moves to the bottom of the printing module 5 (printing station), the screen printing screen is driven by the mobile module to complete the alignment with the battery cell, and is driven by the Z-axis module to drop to contact the carrier 14, and the scraper driving assembly drives the scraper to drop to contact the screen printing screen, and moves in the horizontal direction to complete printing. Then, the scraper rises under the drive of the scraper driving assembly, and the screen printing screen rises under the drive of the Z-axis module, leaves the carrier, and waits for the next printing.

[0059] In some possible implementations, a visual positioning module 6 is further included, which is arranged in front of the printing module 5. The visual positioning module can be a camera or the like.

[0060] Preferably, see Figure 6 Two bearing positions are arranged on each bearing platform 14 along the first direction, and each bearing position carries a battery cell; the printing module 5 includes two printing modules arranged in sequence along the first direction, and the two printing modules print the battery cells of the two bearing platforms respectively.

[0061] For more details, see Figure 6 , the two movers of the first transverse movement device 1201 drive the two carriers 14 to move to the bottom of the two printing modules 5 respectively, and print the battery cells at the first bearing position 14A respectively, and then the two movers drive the carrier 14 to move forward, and print the battery cells at the second bearing positions 14B of the two carriers respectively. It can be understood that in the process of the mover driving the first bearing position 14A of each carrier 14 to the bottom of the printing module, the moving module can drive the screen to match the position of the battery cell carried by the first bearing position 14A, and in the process of driving the second bearing position 14B to move to the bottom of the printing module, the moving module drives the screen to match the position of the battery cell carried by the second bearing position 14B. The printing capacity is greatly improved.

[0062] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
