Technical Field

[0001] This utility model belongs to the field of screen printing technology, specifically relating to a moving mechanism for screen printing solar cells. Background Technology

[0002] Solar cell screen printing machines are mainly used to print electrodes on the surface of solar cells. The electronic paste is evenly printed onto the cell by the moving head of the screen printing machine to form the required electrode pattern.

[0003] In existing solar cell screen printing machines, the printing head slides left and right through a slide rail between the printing head and the support plate. However, because the slider and track that make up the slide rail are in a fully fitted state, the contact area between the slider and track is large, which can easily cause damage after long-term use. Therefore, this utility model proposes a moving mechanism for solar cell screen printing. Utility Model Content

[0004] The purpose of this invention is to provide a moving mechanism for screen printing solar cells, in order to solve the problem mentioned in the background art where the slider and track slide together during operation and have insufficient wear resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moving mechanism for screen printing solar cells, comprising a support plate seat disposed on the surface of the printing machine body and a machine head disposed on the front side of the support plate seat. A slide rail is symmetrically arranged between the machine head and the support plate seat. The slide rail consists of a slider and a track. The slider is fixed to the rear side of the machine head, and the track is fixed to the surface of the support plate seat. The slider and track are in an engaged state. A wear-resistant mechanism is symmetrically arranged at the engagement point of the slider and track. The wear-resistant mechanism consists of a rolling groove, a limiting groove, a rolling block, and a limiting component. The limiting groove is formed on the surface of the track, the rolling groove is formed on the inner wall of the slider, the rolling block is disposed inside the limiting groove and the rolling groove, and the limiting component is disposed inside the rolling block.

[0006] Preferably, the limiting component consists of a mounting hole, a guide sleeve, and a guide post. The mounting hole is opened inside the rolling block, the guide sleeve is disposed inside the mounting hole, and the outer surface of the guide sleeve is fixed to the inner wall of the mounting hole. The guide post passes through the inner side of the guide sleeve, and the two ends of the guide post are respectively fixed to the two sides of the inner wall of the rolling groove.

[0007] Preferably, the guide sleeve is a hollow cylindrical structure, and the guide post is a cylindrical structure.

[0008] Preferably, the length of the limiting groove is less than the length of the track.

[0009] Preferably, bolts are inserted between the symmetrically opened limiting grooves and inside the track, with the ends of the bolts extending to the inside of the support plate.

[0010] Preferably, brush plates are symmetrically installed at the bottom end of the machine head.

[0011] Preferably, an operating table is installed at the bottom of the brush plate and on the surface of the printing machine body, and a limit bracket is provided on the upper part of the operating table.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By designing a wear-resistant mechanism, the problem of wear and tear on the slider and track caused by the reciprocating motion of the printing head during the printing of solar cells in the original screen printing machine is improved. By setting a wear-resistant mechanism between the slider and track, a certain gap is created between the track and slider while ensuring normal use. This increases the wear resistance of the slide rail during use, protects the slide rail, and extends its service life. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a moving mechanism for screen printing solar cells, including a support plate 2 disposed on the surface of the printing machine body 1, and a printing head 3 disposed on the front side of the support plate 2. Slide rails 5 are symmetrically arranged between the printing head 3 and the support plate 2. Each slide rail 5 consists of a slider 51 and a track 52. The slider 51 is fixed to the rear side of the printing head 3, and the track 52 is fixed to the surface of the support plate 2. The slider 51 and track 52 are in an engaged state. Wear-resistant mechanisms are symmetrically arranged at the engagement point of the slider 51 and track 52. Through the designed wear-resistant mechanisms, the problem of wear on the slider 51 and track 52 caused by the reciprocating motion of the printing head 3 during the printing of solar cells in the original screen printing machine is improved. By setting wear-resistant mechanisms between the slider 51 and track 52, a certain gap is created between the track 52 and slider 51 while ensuring normal use, increasing the wear resistance of the slide rail 5 during use. To protect and increase service life, the wear-resistant mechanism consists of a rolling groove 511, a limiting groove 512, a rolling block 513, and a limiting component 514. The limiting groove 512 is opened on the surface of the track 52, the rolling groove 511 is opened on the inner wall of the slider 51, and the rolling block 513 is set inside the limiting groove 512 and the rolling groove 511. The wear-resistant mechanism increases the wear resistance of the slider 51 and the track 52 during operation, and protects the slide rail 5. The limiting component 514 is set inside the rolling block 513. The length of the limiting groove 512 is less than the length of the track 52. Bolts pass through the symmetrically opened limiting grooves 512 and are located inside the track 52, and the ends of the bolts pass through the inner side of the support plate seat 2. Brush plates 4 are symmetrically installed at the bottom of the printing head 3. An operating table is installed at the bottom of the brush plate 4 and on the surface of the printing machine body 1. A limiting bracket is set on the upper part of the operating table to limit the range of movement of the brush plate 4 driven by the printing head 3.

[0021] In this embodiment, preferably, the limiting component 514 consists of a mounting hole 5141, a guide sleeve 5142, and a guide post 5143. The mounting hole 5141 is opened inside the rolling block 513, and the guide sleeve 5142 is disposed inside the mounting hole 5141. The outer surface of the guide sleeve 5142 is fixed to the inner wall of the mounting hole 5141. During the rolling process of the rolling block 513 within the rolling groove 511 and the limiting groove 512, the limiting component 514 limits the movement of the rolling block 513. The guide post 5143 passes through the inner side of the guide sleeve 5142, and both ends of the guide post 5143 are fixed to the inner walls of the rolling groove 511. The guide sleeve 5142 is a hollow cylindrical structure, and the guide post 5143 is a cylindrical structure. The guide sleeve 5142 protects the guide post 5143.

[0022] The working principle and usage process of this utility model are as follows: In the process of screen printing solar cells, the cell is placed on the operating table, and the electronic paste is evenly printed on the cell by the machine head 3 to form the required electrode pattern. During the reciprocating motion of the machine head 3 through the slider 51 and the track 52, the rolling block 513 rolls inside the rolling groove 511 and the limiting groove 512, and is limited by the limiting component 514.
