Technical Field

[0001] This application belongs to the technical field of printing screen meshes, and particularly relates to a flip-type solar cell printing screen mesh and printing equipment. Background Art

[0002] Solar cells can convert light energy into electrical energy under sunlight irradiation and belong to a new energy component with the characteristics of environmental protection and cleanliness. In the existing production process of solar cells, a printing screen mesh is required to extrude the paste onto the substrate in a predetermined form to complete the formation of the electrodes.

[0003] Common printing screen meshes are usually fixed under the squeegee using a tooling. Specifically, the tooling is pre-installed on the support surface and fixed to the screen frame to achieve the positioning of the printing screen mesh.

[0004] The inventor found that when observing the printing effect on the lower side of the printing screen mesh, in order to avoid the printing screen mesh blocking the view, it is necessary to remove the printing screen mesh. However, the process of removing the printing screen mesh is relatively complex, and adverse situations such as paste overflow may occur during the removal process.

[0005] That is to say, there is an urgent need in the prior art for a printing screen mesh that can observe the lower printed matter without being removed. Summary of the Utility Model

[0049] The anti-drop plate 5 is arranged on the side of the net frame 2 facing away from the swing plate 31 , and a connection structure 6 is provided between the anti-drop plate 5 and each of the insertion rods 4 .

[0050] When multiple insertion rods 4 are inserted into multiple through holes 21 one by one, the net frame 2 is manually pushed toward the support 3, so that the net frame 2 can abut against the swing plate 31; at the same time, the anti-slip plate 5 can be connected to the multiple insertion rods 4 through multiple groups of connecting structures 6, so that the anti-slip plate 5 abuts against the side of the net frame 2 facing away from the swing plate 31.

[0051] In the embodiment of the present application, the screen body 1 and the screen frame 2 are limited in their width direction by the cooperation of the through hole 21 and the insertion rod 4; based on this, the screen body 1 and the screen frame 2 are limited in their length direction by the swing plate 31 and the anti-slip plate 5 respectively abutting against the two ends of the screen frame 2, thereby achieving the combination of the screen body 1 and the swing plate 31.

[0052] When the printed matter on the lower side of the screen body 1 needs to be observed, the swing plate 31 can be driven to move relative to the support 3 by rotating the driving member 32, so that the screen body 1 avoids the upper side area of ​​the printed matter.

[0060] In some embodiments, as Figure 4 and Figure 5 shown, grooves 22 are formed on both end faces of the screen frame 2 facing its own length direction; the swinging end face of the swinging plate 31 has a first convex block 312, and the first convex block 312 is adapted to be embedded in any one of the grooves 22 to cooperate with the inserting rod 4 to limit the swaying of the swinging plate 31 in its own width direction.

[0061] In some embodiments, as Figures 5 to 7 shown, the side of the anti - detachment plate 5 facing the screen frame 2 has a second convex block 51, and the second convex block 51 is adapted to be embedded in any one of the grooves 22 to cooperate with the inserting rod 4 to limit the swaying of the swinging plate 31 in its own width direction.

[0062] In some embodiments, as Figures 1 to 3As shown, the rotation driving member 32 is a rotation motor fixedly arranged at the rear side of the printing area; the power output axis of this rotation motor is parallel to the hinge axis of the swing plate 31, and its power output end is in transmission connection with the swing plate 31.

[0063] In some embodiments, as Figure 3 shown, both sides of the screen frame 2 in the direction of its own width have protruding portions 23 extending outward; there are two through holes 21, and the two through holes 21 are respectively arranged on the two protruding portions 23.

[0064] Based on the same inventive concept, an embodiment of the present application further provides a printing device, including a workbench 100 and the flip - type solar cell printing screen mesh proposed in any one of the foregoing.

[0065] The upper side surface of the workbench 100 has two printing stations 110 arranged side by side in the horizontal direction; during printing, the printed matter can be fixed on any one of the printing stations 110.

[0066] The foregoing solar cell printing screen mesh is arranged between the two printing stations 110.

[0067] When the swing plate 31 swings to the horizontal state, the screen body 1 is directly above one of the printing stations 110.

[0068] When it is necessary to observe one of the printed matters, the swing plate 31 can be swung to directly above the other printing station 110, and at this time this printing station 110 can also participate in the printing process.

[0069] The beneficial effects of the printing device provided in this embodiment are the same as those of the foregoing flip - type solar cell printing screen mesh, and will not be elaborated herein.

[0070] In some embodiments, as Figure 1 and Figure 2 shown, the support 3 is embedded in the upper side surface of the workbench 100 so that the swing plate 31 in the horizontal state can contact the upper side surface of the workbench 100, thereby shortening the vertical distance between the screen body 1 and the printing station 110 and ensuring the stability of the printing effect.

[0071] The above content is only the preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
