Abstract
Description
Technical Field
[0001] The invention relates to the technical field of printing and hole filling of green ceramic sheets, in particular to an automatic cleaning mechanism for a workbench used for printing and hole filling. Background Art
[0002] Green tile printing and hole filling are key technologies in the manufacturing of multi-layer co-fired ceramic circuit boards, especially important in applications where circuit patterns are printed on green tiles and interlayer interconnection is required. During the green tile hole filling operation, a conductive paste containing metal powder (such as silver powder, copper powder, etc.) and an organic binder is squeezed through the mesh using a squeegee at a specific pressure and speed into the corresponding through-holes in the green tile. Finally, a sintering process fuses the metal powder to form a continuous conductive path.
[0003] During traditional printing and hole-filling operations, after the metal slurry is transferred through the screen or filled into the raw ceramic sheet, the excess slurry will pass through the holes in the raw ceramic sheet and remain on the work surface, thereby contaminating the work table. In the case of continuous production operations, if the slurry remaining on the surface of the work table cannot be removed in time, it will cause irreversible contamination to the lower surface of the raw ceramic sheet that needs to be processed later, resulting in problems such as a decrease in yield rate or even product scrapping, resulting in a waste of production raw materials and increased production costs. Since the organic binder in the metal slurry evaporates quickly, the metal slurry remaining on the work table after printing and hole-filling is particularly difficult to clean. It usually requires manual use of a dust-free cloth dipped in organic solvents such as alcohol to wipe it promptly and multiple times. The cleaning effect is poor and the efficiency is low, which seriously affects production efficiency. In addition, organic solvents such as alcohol will cause irreversible corrosion to the work table, greatly shortening the service life of the work table. Therefore, there is an urgent need for a mechanism that can automatically clean the work table during printing and hole-filling to ensure the service life of the work table, reduce production costs, improve labor productivity, and increase the yield rate of multi-layer co-fired ceramic substrate products.

[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0018] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention.

Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0019] Please refer to Figure 1-4 , an automatic cleaning mechanism for a workbench for printing and filling holes, comprising a base plate 1, on which a platen fixing plate 1 2 and a platen fixing plate 2 3 are mounted side by side, a left mounting plate 4 and a right mounting plate 5 are fixedly mounted at both ends of the platen fixing plate 1 2 and the platen fixing plate 2 3, a workbench adapter plate 6 is mounted at both ends of the opposite sides of the platen fixing plate 1 2 and the platen fixing plate 2 3, and a micro-hole workbench 7 is fixedly mounted on the left mounting plate 4, the right mounting plate 5 and the workbench adapter plate 6;
[0020] A servo motor 8 is installed at both ends of the outer side of the left mounting plate 4, and a coupling 9 is installed on the output shaft of the servo motor 8. The coupling 9 is connected to one end of the hexagonal profile 10. A breathable paper roll 11 is installed on the hexagonal profile 10. Paper roll fixing blocks 12 are installed at both ends of the breathable paper roll 11, and the paper roll fixing block 12 is fixed with a locking screw.
[0021] A top block 13 is provided at one end of the hexagonal profile 10 away from the coupling 9, and a spring 14 is provided on the top block 13. The spring 14 is located in a spring sleeve 15, and the spring sleeve 15 is arranged on the right mounting plate 5. A baffle 16 is installed on the right mounting plate 5. The baffle 16 limits the top block 13 to the spring sleeve 15 and limits the spring sleeve 15 to the right mounting plate 5.
[0022] Bearing seats 17 are respectively installed on the left mounting plate 4 and the right mounting plate 5, and a fixing ring 18 is installed on the outside of the bearing seat 17. The fixing ring 18 is used to limit the bearing seat 17. A paper roll guide shaft 19 is rotatably installed between the two opposite limiting bearing seats 17. The paper roll guide shaft 19 passes through the fixing ring 18 and the bearing seat 17 on the outside of the left mounting plate 4, the left mounting plate 4, the right mounting plate 5, the bearing seat 17 and the fixing ring 18 on the outside of the right mounting plate 5 in sequence. A cam 22 is installed on one end of the paper roll guide shaft 19 on the right mounting plate 5, and a speed sensor mounting plate 20 is installed on the outside of the right mounting plate 5. A photoelectric sensor 21 is installed on the speed sensor mounting plate 20. The photoelectric sensor 21 is close to the cam 22 and is used to sense and count the number of rotations of the cam 22.
[0023] Before production, one end of the breathable paper roll 11 is passed around the front and rear two paper roll guide shafts 19 and fixed to the reel of the breathable paper roll 11 at the other end. By setting the speed values of the two sets of servo motors 8 in front and behind the workbench, the running directions of the two sets of servo motors 8 must be consistent, so that the breathable paper on the paper roll guide shaft 19 is tightened and straight, does not slip on the roll guide shaft, and is flat on the surface of the microporous workbench 7.
[0024] During production, the printed hole-filling raw ceramic sheet is placed on the microporous workbench 7, and the program controls the negative pressure of the workbench to be turned on, and the raw ceramic sheet is adsorbed and fixed through the breathable paper, thereby preventing the printing slurry from contaminating the microporous workbench 7; then the printing hole-filling process is carried out. After the printing hole-filling process is completed, the raw ceramic sheet is manually removed, and the program controls the two sets of servo motors 8 to operate. The contaminated breathable paper on the microporous workbench 7 moves in the direction of operation of the servo motor 8. Under the action of friction, the paper roll guide shaft 19 starts to rotate, driving the cam 22 installed at the end of the paper roll guide shaft 19 to rotate. By counting the number of times the gap on the cam 22 passes through the photoelectric sensor 21, the number of rotations of the paper roll guide shaft 19 can be obtained, and then the paper feeding distance of the breathable paper can be obtained.
[0025] By converting the paper feeding distance of the breathable paper roll 11 into the number of times the gap on the cam 22 passes the photoelectric sensor 21, and coordinating the start and stop of the servo motor 8 with program control, the paper feeding distance preset by the program can be accurately controlled and achieved, so that the contaminated breathable paper roll 11 can be automatically inserted into the empty paper roll core, and the new breathable paper can be spread flat on the microporous workbench 7 to prevent the surface of the microporous workbench 7 from being contaminated.
[0026] Breathable paper is used to separate the raw ceramic sheet from the microporous workbench 7, thereby preventing the microporous workbench 7 from being contaminated without affecting the adsorption and fixing effect of the microporous workbench 7 on the raw ceramic sheet; by adjusting the speed of the dual servo motors 8 and coordinating the height difference between the paper roll guide shaft 19 and the table surface of the microporous workbench 7, the breathable paper is stretched and spread flat on the table surface of the microporous workbench 7, realizing seamless connection and replacement of old paper with new paper; the paper feeding distance of the breathable paper is converted into a control method of the number of times the gap on the cam 22 passes through the photoelectric sensor 21, and coordinated with the start and stop of the servo motor 8 to achieve the purpose of accurately controlling the paper feeding distance.
[0027] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
