[0030] Specifically: the forward and reverse motor 201 can be started through the control terminal 104, and the operation of the forward and reverse motor 201 can drive the threaded rod 202 to rotate forward or reverse. At this time, the U-shaped movable plate 203 can move on the surface of the threaded rod 202. Since the other side of the U-shaped movable plate 203 moves on the surface of the sliding rod 204, the U-shaped movable plate 203 can be limited and moved, and when the U-shaped movable plate 203 moves, it can drive the scraper 205 to scrape the ink sprayed on the screen printing plate 403 by multiple ink nozzles 206, so as to perform silk screen printing on the touch screen cover.
[0031] In one embodiment, handles 601 are installed on both sides of the placement frame 6, legs 602 are installed at the four ends of the bottom of the placement frame 6, mounting blocks 603 are installed at the bottom of both sides of the inner wall of the placement frame 6, knob bolts 604 are movably embedded on the surfaces of the two mounting blocks 603, movable plates 605 are installed at one end of the two knob bolts 604 through bearings, limiting plates 606 are installed on both sides of the movable plates 605, movable grooves 607 are opened on both sides of the inner wall of the placement frame 6, and the two limiting plates 606 are movable inside the two movable grooves 607.
[0032] Specifically: two handles 601 are used to facilitate placing the placement frame 6 into the placement groove 502, and the four legs 602 can be placed at the four ends of the placement groove 502, so that the four legs 602 can limit the placement frame 6 and place it inside the placement groove 502. By placing the touch screen cover on the surface of the movable plate 605, the outer side of the touch screen cover can be fitted with the inner side of the placement frame 6, which is convenient for limiting the placement of the touch screen cover and preventing it from moving. By turning the two knob bolts 604, the knob bolts 604 can drive the movable plate 605 upward or downward when turning, thereby facilitating the removal of the touch screen cover on the movable plate 605.
[0033] In one embodiment, one end of the connecting hose 301 is embedded and installed on the surface of the U-shaped movable plate 203 , and the connecting hose 301 is communicated with the interior of the plurality of ink nozzles 206 .
[0034] Specifically: the ink nozzle 206 is a common ink cartridge inkjet head structure in the prior art. In the tiny nozzle holes of the inkjet head, the ink is heated to generate bubbles, and the ink is driven out by the vapor pressure of the ink. The specific structure is not described in detail; the ink inside the ink cartridge 3 can be transported to the interior of multiple ink nozzles 206 through the connecting hose 301, and the circuit connected to the ink cartridge 3 is electrically connected to the control terminal 104, and the ink can be sprayed out from the interior of multiple ink nozzles 206 through the control terminal 104.
[0035] In one embodiment, the two connecting blocks 503 are movable inside the two moving grooves 106 .
[0036] Specifically, when the connection plate 501 is being lifted or lowered, the two connection blocks 503 are both movable inside the two moving grooves 106 , so that the lifting and lowering movement of the connection plate 501 is more stable.
[0037] Working principle: the forward and reverse motors 201, the electric push rod 5 are electrically connected to the control terminal 104. When the touch screen cover is screen printed, the handle 102 can be used to open the switch door 101, and the screen printing plate 403 is placed inside the two placement slots 401. The two knob bolts 402 are screwed down so that the wear-resistant gaskets at the bottom of the knob bolts 402 are attached to the surface of the outer frame of the screen printing plate 403, thereby fixing the placement of the screen printing plate 403. The touch screen cover that needs to be screen printed is placed inside the placement frame 6. The touch screen cover can be pressed against the inner side of the placement frame 6 to limit the position, so that the touch screen cover is located on the surface of the movable plate 605. The placement frame is moved using the two handles 601. The four legs 602 at the bottom of the frame 6 are placed inside the placement slot 502, and the switch door 101 is closed. The two electric push rods 5 can be started synchronously through the control terminal 104. The two electric push rods 5 operate and drive the connecting plate 501 upward, so that the touch screen cover plate placed inside the placement frame 6 is attached to the bottom of the screen printing plate 403. The forward and reverse motors 201 are started through the control terminal 104. The forward and reverse motors 201 operate and drive the threaded rods 202 to rotate forward and reverse. The ink inside the ink cartridge 3 is transported to the multiple ink nozzles 206 through the connecting hose 301, and then the ink can be sprayed onto the top of the screen printing plate 403 through the multiple ink nozzles 206. At this time, the U-shaped movable plate 2 03 can drive multiple ink nozzles 206 at the bottom to move and spray ink. During the movement, the scraper 205 can scrape the ink sprayed on the surface of the screen printing plate 403, so as to perform screen printing on the touch screen cover. The touch screen cover is placed on the inner side of the placement frame 6 and raised to fit the bottom of the screen printing plate 403, so as to achieve accurate positioning during the screen printing process, and avoid the position deviation of the screen printing on the touch screen cover, which affects the effect of the screen printing on the touch screen cover; after the screen printing is completed, the electric push rod 5 is controlled by the control terminal 104, and the electric push rod 5 operates and drives the connecting plate 501 downward, and the placement frame 6 is taken out from the inside of the placement slot 502 using two handles 601, and then the placement frame 6 is taken out from the inside of the placement slot 502 by The two knob bolts 604 are turned in one direction at the same time. Since the bottom end of the movable plate 605 is connected to one end of the two knob bolts 604 through a bearing, the knob bolt 604 can drive the movable plate 605 to move upward when being turned, and the limit plates 606 on both sides of the movable plate 605 can move inside the two movable grooves 607 during the movement, which can be used to support the stability of the movable plate 605, so that the movable plate 605 moves upward to a position above the top of the placement frame 6. At this time, the touch screen cover placed on the surface of the movable plate 605 can be taken out, which can avoid directly touching the surface of the touch screen cover to cause ink damage, and can improve the quality of product production.
