[0026] In order to make the purpose, technical scheme and advantages of the present application embodiment clearer, the technical scheme of the present application embodiment will be described clearly and completely in combination with the drawings in the present application embodiment. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.

[0027] The embodiments of the present application will be described below in combination with Figures 1 to 3

[0028] According to the embodiments of the present application, on the one hand, as Figure 1 ​As shown, a printing workbench is provided, comprising a base 1 and a bearing platform 2. The bearing platform 2 is arranged on the base 1, and a bearing surface 203 is formed on a side of the bearing platform 2 away from the base 1. A vacuum pipeline 2021 and a cooling pipeline 2011 are formed in the bearing platform 2, and the vacuum pipeline 2021 and the cooling pipeline 2011 are arranged in layers. The vacuum pipeline 2021 is arranged closer to the bearing surface 203 than the cooling pipeline 2011. The bearing platform 2 is provided with a suction hole 3 corresponding to the bearing surface 203. The suction hole 3 is in communication with the vacuum pipeline 2021, and the vacuum pipeline 2021 is adapted to be connected to a negative pressure source.

[0029] By arranging the vacuum pipeline 2021 and the cooling pipeline 2011 in layers in the bearing platform 2, the battery piece can be cooled while being fixed on the bearing platform 2. Therefore, when the hot-melt inkjet printing is performed, the high-temperature hot-melt ink jetted from the nozzle can quickly solidify into a solid pattern when falling on the low-temperature battery piece, which is beneficial to improving the uniformity of the pattern line width and reducing the defect rate of the battery piece.

[0030] Specifically, the base 1 is provided with a mounting groove in the form of a recessed surface of the base 1. The bearing platform 2 is arranged in the mounting groove. In this embodiment, the printing of the battery piece is hot-melt inkjet printing. The high-temperature ink droplets may splash, or the excess ink droplets may flow from the bearing platform 2 to the base 1. Therefore, the bearing platform 2 is arranged in the mounting groove, so that the base 1 can collect the splashed or flowed ink droplets through the mounting groove, thereby avoiding damage or pollution to the structure outside the printing workbench caused by the high-temperature ink droplets.

[0031] It should be noted that the solidification rate of the high-temperature ink droplets on the surface of the battery piece in the hot-melt inkjet printing affects the printing efficiency of the mask pattern on the surface of the battery piece and the quality of the mask pattern. Through practice, it is found that in the printing inkjet, the battery piece adsorbed on the vacuum platform is controlled at a temperature of 5-10℃. The high-temperature ink jetted from the nozzle falls on the low-temperature battery piece, so that the hot-melt ink can quickly solidify into a solid pattern, and the line width of the pattern is ensured to be the same.

[0032] In one embodiment, as Figure 1As shown, the adsorption holes 3 include a first adsorption hole 301 and a second adsorption hole 302. There are a plurality of first adsorption holes 301, which are arranged in an array on the carrier 2. The carrier 2 has a square structure so that the carrier surface 203 is a square surface. There are a plurality of second adsorption holes 302, which are arranged corresponding to the four corners of the carrier surface 203. The first adsorption holes 301 arranged in an array allow the battery cell to be adsorbed evenly on the carrier 2. The second adsorption holes 302 provided at the four corners of the carrier surface 203 increase the suction force at the corners of the battery cell, further allowing the battery cell to be adsorbed even more evenly on the carrier 2, thereby improving the printing quality of the corner pattern lines in the battery cell printing and avoiding the problem of uneven pattern lines.

[0033] It should be noted that, through practice, it has been found that when the battery cell is vacuum-adsorbed during printing, the four corners of the battery cell will always be lifted up. Therefore, by setting second adsorption holes 302 at the four corners of the supporting surface 203, the adsorption force at the corners of the battery cell is increased, so that the battery cell can be adsorbed more flatly on the supporting platform 2, thereby improving the printing quality of the battery cell after printing and avoiding the problem of uneven pattern lines.

[0034] In one embodiment, Figure 2 As shown, there are a plurality of vacuum lines 2021 and a plurality of adsorption holes 3. The plurality of vacuum lines 2021 are arranged crosswise in the horizontal and vertical directions, so that the plurality of vacuum lines 2021 correspond to the plurality of first adsorption holes 301 and the plurality of second adsorption holes 302. By arranging a plurality of vacuum lines 2021 corresponding to the plurality of adsorption holes 3, the suction force of any first adsorption hole 301 and any second adsorption hole 302 is kept consistent, allowing the battery cell to be more evenly adsorbed on the support platform 2.

[0035] In one embodiment, Figure 1 As shown, there are at least two second adsorption holes 302 located at each vertex of the support surface 203. By providing at least two second adsorption holes 302 at each vertex, the suction force on the corners of the battery cell is further improved, so that the battery cell is more evenly adsorbed on the support platform 2.

[0036] Specifically, if Figure 1 As shown, by setting at least two second adsorption holes 302 at the top corner positions of the adsorption platform 202, the total number of adsorption holes 3 at the top corner positions is increased, and the adsorption holes 3 are set more densely, thereby increasing the adsorption force at the top corner positions, making the battery cell adsorbed more flat, and avoiding unevenness of the printed pattern lines at the four corners of the battery cell after printing.

[0037] In one embodiment, Figure 1As shown, the bearing table 2 comprises a cooling platform 201, which is arranged on the base 1, and a cooling pipeline 2011 arranged in the cooling platform 201 and adapted to pass cooling water.

[0038] Specifically, the cooling pipeline 2011 is provided with an inlet and an outlet, and the cooling water flows into the cooling pipeline 2011 through the inlet and flows out of the outlet, so as to realize the circulation of the cooling water.

[0039] Specifically, as shown in the drawings, Figure 3 the cooling pipeline 2011 is arranged corresponding to the edge position of the cooling platform 201, so that the circulating cooling water can uniformly cool the battery piece, thereby keeping the temperature of each position of the battery piece consistent.

[0040] In an embodiment, as shown in the drawings, Figure 1 the bearing table 2 further comprises an adsorption platform 202 arranged on the cooling platform 201, and the upper surface of the adsorption platform 202 forms a supporting surface, and a vacuum pipeline 2021 is arranged in the adsorption platform 202, and the adsorption hole 3 is arranged in communication with the negative pressure through the vacuum pipeline 2021.

[0041] It should be noted that the cooling platform 201 and the adsorption platform 202 can be an integrated structure, i.e. the above-mentioned bearing table 2 structure, which only needs to be layered inside the bearing table 2, and the vacuum pipeline 2021 is arranged near the upper part, and the cooling pipeline 2011 is arranged near the lower part; or the cooling platform 201 and the adsorption platform 202 are a split structure, and the cooling platform 201 and the adsorption platform 202 are detachably connected, so as to facilitate the maintenance and replacement of the two platforms.

[0042] In an embodiment, as shown in the drawings, Figure 1 and Figure 2 the printing workbench further comprises a limiting structure 4 arranged corresponding to the outer periphery of the bearing table 2, and the limiting structure 4 protrudes upward along the vertical direction and is arranged on the adsorption platform 202.

[0043] In an embodiment, as shown in the drawings, Figure 1 and Figure 2 the limiting structure 4 is circumferentially spaced apart along the edge of the cooling platform 201. By arranging a plurality of limiting structures 4, the battery piece can be fully limited, so as to avoid displacement of the battery piece during the printing process and improve the printing quality of the battery piece.

[0044] In an embodiment, as shown in the drawings, Figure 1 and Figure 2As shown, the bottom of the base 1 is provided with a switch piece 5, which is suitable for controlling the on-off of the cooling pipeline 2011.

[0045] Specifically, two connecting ports are respectively arranged on the base 1 corresponding to the water inlet and the water outlet on the cooling pipeline 2011, and the switch piece 5 is connected with the water inlet and the water outlet through the two connecting ports respectively to control the on-off of the cooling pipeline 2011.

[0046] Specifically, the installation groove is arranged to collect the cooling water overflowing from the connecting position of the connecting port and the water inlet or the water outlet, so as to avoid damaging the electrical elements by the cooling water.

[0047] According to the embodiments of the utility model, on the other hand, a kind of graph printing equipment is also provided, including above-mentioned graph printing workstation.
