Description

Technical Field

[0001] The utility model belongs to the technical field of screen printing, in particular to an oblique angle scraping device. Background Art

[0002] With the progress of society and the development of science and technology, solar panels are being used more and more widely. One of the processes in the existing solar panel manufacturing process requires printing a slurry onto a silk screen by using a squeegee. The screen is provided with a number of fine grid lines. During the printing process, the squeegee moves to print the slurry through the grid lines onto the silicon wafer.

[0003] Most of the existing scrapers are rectangular, forming a certain angle between the scraper and the screen. The scraper moves along the length of the grid line, squeezing the slurry into the grid line during the movement of the scraper. In the process of pushing the slurry along the length of the grid line, the slurry is only subjected to a force parallel to the grid line, and the slurry can only enter the grid line from top to bottom. However, some silk screen interweaving nodes of the screen may be just above the grid line, and some grid lines may not be filled solidly, which may easily lead to broken grids and virtual printing during printing. Utility Model Content

[0004] In order to solve the problems in the above-mentioned background technology, the utility model provides an angled scraper device, in which the knife holder drives the scraper to move along the length direction of the grid line through the support plate, and the slurry enters the grid line under the push of the scraper, and the slurry is pressed into the grid line from above the grid line under the action of the inclined surface. At the same time, the slurry is subjected to a lateral force under the action of the inclined edge, so that the slurry is pressed into the grid line on the side above the grid line, and the slurry enters the grid line from the side through the space next to the screen node. The lateral force causes the slurry entering the grid line to be squeezed against the inner wall of the grid line, so that the slurry fills the grid line, reduces the phenomenon of broken grid and virtual printing, and improves the printing effect.

[0005] The utility model provides an angled scraper device, comprising a knife holder connected to a support plate, the support plate fixedly connected to the scraper, a beveled surface on one side of the scraper, and a beveled edge on the bottom of the scraper.

[0008] Furthermore, guide plates are respectively connected to both sides of the tool holder.

[0009] Furthermore, a connecting assembly for fixing the guide plate is provided between each guide plate and the tool holder.

[0010] Furthermore, the connecting assembly includes a first connecting block that abuts against the upper surface of the tool holder, the first connecting block is integrally formed with a second connecting block, the guide plate is connected to the side wall of the second connecting block, the upper surface of the first connecting block is provided with a first connecting groove along the length direction of the tool holder, a second bolt passes through the first connecting groove, and the second bolt is threadedly connected to the tool holder.

[0011] Furthermore, the guide plate is provided with a second connecting groove along the vertical direction, a third bolt passes through the second connecting groove, and the third bolt is threadedly connected to the second connecting block.

[0012] Furthermore, the second connecting block is fixedly connected with at least two limiting columns which are slidably plugged into the second connecting grooves.

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following is combined with Figure 1 To the attached Figure 3 And specific embodiments discuss the present invention in detail.

[0024] like Figures 1 to 3 As shown, the utility model provides an angled scraping device, including a tool holder 1, which is detachably connected to a support plate 2, and a disassembly component 3 is provided between the tool holder 1 and the support plate 2, which connects and fixes the support plate 2 to the tool holder 1.

[0025] A squeegee 4 is fixedly attached to the support plate 2. The squeegee 4 is positioned above the screen, with its lower edge slidingly abutting against the upper surface of the screen. The squeegee 4 has a vertical cross-section that is a right-angled trapezoid. A bevel 41 is defined on the side of the squeegee 4 facing away from the support plate 2. The vertical cross-sectional area of ​​the squeegee 4 decreases along its length, and a beveled edge 42 is defined at the bottom of the squeegee 4.

[0026] The tool holder 1 drives the scraper 4 to move along the length direction of the grid line through the support plate 2. The slurry enters the grid line under the push of the scraper 4. The slurry is pressed into the grid line from above the grid line under the action of the inclined surface 41. At the same time, the slurry is subjected to a lateral force under the action of the inclined edge 42, so that the slurry is pressed into the grid line on the side above the grid line. The slurry enters the grid line from the side through the space next to the screen node. The lateral force squeezes the slurry entering the grid line and the inner wall of the grid line, so that the slurry fills the grid line, reduces the phenomenon of broken grid and virtual printing, and improves the printing effect.

[0027] When the scraper 4 is worn out after being used for a period of time and needs to be replaced, the disassembly component 3 releases the restriction on the support plate 2, replaces the new support plate 2 and scraper 4, and then the support plate 2 is connected and fixed to the tool holder 1 through the disassembly component 3.

[0028] The disassembly assembly 3 includes a fixing plate 31, and the support plate 2 is placed between the fixing plate 31 and the tool holder 1. A plurality of first bolts 32 pass through the fixing plate 31. The first bolts 32 pass through the fixing plate 31 and the support plate 2 and are threadedly connected to the tool holder 1. The first bolts 32 connect and fix the fixing plate 31, the support plate 2 and the tool holder 1.

[0029] When the scraper 4 needs to be replaced, separate the first bolt 32 from the fixing plate 31, separate the fixing plate 31 from the support plate 2, remove the support plate 2, and then replace the new support plate 2 and scraper 4, and then connect and fix the fixing plate 31, support plate 2 and tool holder 1 with the first bolt 32.

[0030] Guide plates 5 are provided on either side of the blade holder 1. Connecting assemblies 6 are provided between each guide plate 5 and the blade holder 1 to securely connect the guide plates 5 to the blade holder 1. During the movement of the squeegee 4, the guide plates 5 are used to gather the slurry near the sides of the squeegee 4 toward the center, reducing slurry waste and ensuring more effective slurry utilization.

[0031] Each connecting assembly 6 includes a first connecting block 61, the lower surface of the first connecting block 61 abuts against the upper surface of the tool holder 1, the upper surface of the first connecting block 61 is provided with a first connecting groove 611 arranged along the length direction of the tool holder 1, a second bolt 62 passes through the first connecting groove 611, the second bolt 62 is threadedly connected to the tool holder 1, and the first connecting block 61 is connected and fixed to the tool holder 1 by the second bolt 62.

[0032] The side wall of the first connecting block 61 is integrally formed with a second connecting block 63, and the guide plate 5 abuts against the side wall of the second connecting block 63. The guide plate 5 is provided with a second connecting groove 51 arranged along the height direction of the tool holder 1. A third bolt 64 passes through the second connecting groove 51. The third bolt 64 is threadedly connected to the second connecting block 63, and the guide plate 5 is fixed to the second connecting block 63 by the third bolt 64.

[0033] To adjust the distance between the two guide plates 5, loosen the second bolt 62 and adjust the position of the first connecting block 61 along the length of the tool holder 1. The first connecting block 61 drives the guide plates 5 to move via the second connecting block 63. After the position of the guide plates 5 is adjusted, tighten the second bolt 62. The second bolt 62 secures the first connecting block 61 to the tool holder 1. To adjust the height of the guide plates 5, loosen the third bolt 64 and adjust the position of the guide plates 5 vertically. After the vertical position of the guide plates 5 is adjusted, tighten the third bolt 64. The third bolt 64 secures the guide plates 5 to the second connecting block 63.

[0034] A pair of limiting posts 631 are fixedly connected to one side of the second connecting block 63 close to the second connecting groove 51. The limiting posts 631 are slidably plugged into the second connecting groove 51. The second limiting posts 631 reduce the possibility of the guide plate 5 being offset when the guide plate 5 is adjusted in height along the vertical direction.

[0035] The implementation principle of the bevel scraper device provided by the utility model is as follows: the knife holder 1 drives the scraper 4 to move along the length direction of the grid line through the support plate 2, and the slurry enters the grid line under the push of the scraper 4, and the slurry is pressed into the grid line from above the grid line under the action of the inclined surface 41. At the same time, the slurry is subjected to a lateral force under the action of the inclined edge 42, so that the slurry is pressed into the grid line on the side above the grid line, and the slurry enters the grid line from the side through the space next to the wire mesh node. The slurry entering the grid line is squeezed against the inner wall of the grid line by the lateral force, so that the slurry fills the grid line.
