[0021] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0023] As Figure 1 shown, the present application provides a PCB double-sided ink printing machine, including a workbench 1, which is arranged in a PCB (hereinafter simply referred to as material) processing workshop. On one side of the top of the workbench 1, there is a support component 3 for placing materials. At the same time, on one side of the support component 3, there is a printing component 2 for ink printing on the materials on the top of the support component 3;

[0024] As Figure 2 shown, the printing component 2 includes a column 21, which is fixedly installed on the workbench 1. At the same time, a mounting frame 22 is slidably installed on one side of the column 21. The mounting frame 22 is adapted to reciprocate on the column 21. At the same time, fixed frames 23 are arranged at both ends of the mounting frame 22, and a claw 25 is arranged on each group of fixed frames 23. At the same time, a screen plate 24 is arranged between the two claws 25. The two ends of the screen plate 24 are clamped and fixed by the two claws 25, and the bottom of the screen plate 24 is in contact with the material;

[0025] Meanwhile, a printing head 6 is slidably mounted on the mounting frame 22, and a motor is fixedly mounted on the back side of the mounting frame 22. A transmission part is provided between the output end of the motor and the printing head 6. In this embodiment, the transmission part is a belt transmission mechanism, so that the printing head 6 is adapted to reciprocate on the mounting frame 22;

[0026] The printing head 6 includes a squeegee and a doctor blade. The squeegee and the doctor blade are used to push the ink paste to reciprocate on the stencil 24, thereby driving the ink coating to spread on the stencil 24, ensuring the uniform distribution of the ink paste on the stencil, and thus realizing high-quality printing of the material.

[0027] As Figure 3 shown, the support assembly 3 includes two groups of brackets 31. The two groups of brackets 31 are fixedly mounted on the top of the workbench 1. At the same time, a bottom plate 32 is placed on the tops of the two groups of brackets 31. A receiving groove 33 is provided in the bottom plate 32. The size of the receiving groove 33 is adapted to the size of the material. During printing, the material will be embedded in the receiving groove 33, and the thickness of the material is greater than the depth of the receiving groove 33;

[0028] At the same time, a plurality of fixing columns 4 are provided between the two groups of brackets 31. A suction cup 41 is provided at the top of the fixing column 4. The suction cup 41 is used to fix the bottom surface of the bottom plate 32 to prevent the bottom plate 32 from shaking during printing.

[0029] During printing, first place the material in the receiving groove 33, then control the position of the mounting frame 22 so that the stencil 24 contacts the top of the material, and then control the printing head 6 to move on the stencil 24, so that the ink is printed on the material. At this time, the single-sided printing work can be completed.

[0030] At the same time, a slide rail 5 is provided at the bottom of one of the groups of brackets 31. A cylinder 51 is slidably mounted on the slide rail 5, and a push plate 52 is fixedly mounted on the output end of the cylinder 51. At the same time, a through groove 34 is provided on one side in the receiving groove 33. The through groove 34 penetrates the receiving groove 33, and the size of the receiving groove 33 is adapted to the size of the push plate 52;

[0031] When the material needs to be turned over, control the cylinder 51 to drive the push plate 52 to extend. At this time, the push plate 52 will enter the receiving groove 33 through the through groove 34 and push one side of the material to tilt. At this time, the operator can quickly grab the material and turn it over, so that the material can quickly perform the printing work on the second side.

[0032] At the same time, when the support assembly 3 supports bottom plates 32 of different sizes, the operator can adjust the position of the cylinder 51 on the slide rail 5 so that the push plate 52 can move to the corresponding through groove 34, thereby realizing the ejection of materials of different sizes, enabling the machine to flexibly process circuit boards of various specifications.

[0033] In summary, by setting the support component 3, after one-sided printing of the material is completed, one side of the material can be ejected, which enables the staff to easily grasp the material and perform the turning operation for the second-sided printing work, improving production efficiency and enhancing the operation convenience and flexibility of the device.

[0034] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
