One end of a rotating roller 301 extends to the back of the T-shaped plate 201 and is fixed with a second transmission wheel 306. A third transmission wheel 307 is fixed on the surface of the connecting shaft 2010. Two transmission belts 308 are sleeved on the surface of the first transmission wheel 305, and the other ends of the two transmission belts 308 are respectively sleeved on the surfaces of the second transmission wheel 306 and the third transmission wheel 307.

[0036] Specifically, the rotation of the connecting shaft 2010 drives the third transmission wheel 307 to rotate. The rotation of the third transmission wheel 307 drives the first transmission wheel 305 to rotate via a transmission belt 308. The rotation of the first transmission wheel 305 drives the second transmission wheel 306 to rotate via another transmission belt 308. The rotation of the second transmission wheel 306 drives the rotating roller 301 to rotate. The rotation of the rotating roller 301 drives the conveying roller 302 to rotate, thereby realizing the automatic conveying of the viscous conveyor belt 303, and thus realizing the automatic conveying of the soft substrate.

[0037] Please refer to this carefully. Figure 5 , Figure 7 , Figure 8 A vertical rod 402 is rotatably mounted on the inner bottom wall of the rectangular cover 209, and a first bevel gear 403 that meshes with each other is fixedly mounted on the top of the vertical rod 402 and the surface of the connecting shaft 2010. An installation groove and a strip groove are respectively opened on the upper surface of the equipment platform 100.

[0038] Specifically, the rotation of the connecting shaft 2010 drives the vertical rod 402 to rotate under the action of the two first bevel gears 403. The rotation of the vertical rod 402 drives the horizontal shaft 405 to rotate under the action of the two second bevel gears 406. The rotation of the horizontal shaft 405 drives the reciprocating screw 404 to rotate under the action of the two third bevel gears 407.

[0039] Please refer to this carefully. Figure 7 A rectangular slider 408 is slidably provided on the inner wall of the strip groove. The surface of the rectangular slider 408 is provided with a threaded groove that is threaded to the outer surface of the reciprocating screw 404. A rectangular insert is fixed on the lower surface of the mold plate 401. A rectangular insertion groove that matches the rectangular insert is provided on the upper surface of the rectangular slider 408.

[0040] Specifically, it facilitates the replacement of mold plate 401 to apply film to hard substrates of different specifications.

[0041] In this embodiment, by setting up a material-grabbing and film-applying mechanism 200, a soft substrate conveying mechanism 300, and a hard substrate conveying mechanism 400, the equipment can first adhere the soft substrate to the outer surface of the adhesive conveyor belt 303 at equal intervals during film application, and then place the hard substrate in the mold groove on the mold plate 401. Afterwards, the drive motor 207 is started to drive the connecting shaft 2010 to rotate. The rotation of the connecting shaft 2010 drives the rotating shaft 202 and the cylindrical platform 203 to rotate. The rotation of the cylindrical platform 203 causes the material-grabbing plate 205 at the top of the cylindrical platform 203 to face the adhesive conveyor belt. At this point, the hydraulic rod 204 is activated to move the material-taking plate 205 upwards, allowing it to adhere to the soft substrate on the adhesive conveyor belt 303. Then, the vacuum generator 208 is activated to effectively adsorb the soft substrate. Next, the drive motor 207 is driven to rotate the material-taking plate 205, which has adsorbed the soft substrate, until it is directly facing the hard substrate on the mold plate 401. Then, the hydraulic rod 204 is activated again to move the material-taking plate 205 downwards, allowing the soft substrate to adhere to the surface of the hard substrate. The vacuum generator 208 is then activated again, preventing the negative pressure adsorption holes 206 from adsorbing the soft substrate. The substrate is adsorbed, thus achieving automatic film application. Furthermore, during the rotation of the cylindrical platform 203, the rotation of the connecting shaft 2010 drives the third transmission wheel 307 to rotate. The rotation of the third transmission wheel 307 drives the first transmission wheel 305 to rotate via a transmission belt 308. The rotation of the first transmission wheel 305 drives the second transmission wheel 306 to rotate via another transmission belt 308. The rotation of the second transmission wheel 306 drives the rotating roller 301 to rotate. The rotation of the rotating roller 301 drives the conveyor roller 302 to rotate, thereby realizing the adhesion of the conveyor belt 303. Automatic conveying enables the automatic conveying of soft substrates. Simultaneously, the rotation of connecting shaft 2010 drives the vertical rod 402 to rotate under the action of two first bevel gears 403. The rotation of the vertical rod 402 drives the horizontal shaft 405 to rotate under the action of two second bevel gears 406. The rotation of the horizontal shaft 405 drives the reciprocating screw 404 to rotate under the action of two third bevel gears 407, thereby driving the rectangular slider 408 to move, which in turn drives the mold plate 401 to move automatically, realizing the automatic conveying of hard substrates and thus achieving the purpose of continuous automated film application.

[0042] Example 2 Based on Example 1, referring to Figures 2 to 4 And unlike Example 1, the following is true: Please refer to this carefully. Figure 3 , Figure 4 The front side of the T-shaped plate 201 is provided with a cleaning mechanism 500 for cleaning the surfaces of the soft and hard substrates before applying the film.

[0043] Specifically, it can effectively clean the bonding surfaces of soft and hard substrates.

[0044] Please refer to this carefully. Figure 3 , Figure 4 The cleaning mechanism 500 includes a pipe 501 fixed on the front of the T-shaped plate 201, and two sets of jet heads 502 symmetrically arranged on the surface of the pipe 501. Both sets of jet heads 502 are inclined on the surface of the pipe 501.

[0045] Specifically, it can use two sets of jet nozzles 502 to blow air to clean the opposite surfaces of the soft substrate and the hard substrate respectively.

[0046] Please refer to this carefully. Figure 3 , Figure 4 The cleaning mechanism 500 also includes a rectangular plate 503 slidably disposed on the inner wall of the rectangular cover 209, and a rectangular telescopic airbag 504 fixed on the inner wall of the rectangular cover 209. The ends of the rectangular telescopic airbag 504 are respectively provided with an air intake pipe and an air inflation pipe. The surface of the air intake pipe is provided with a filter cover. The end of the air inflation pipe extends into the interior of the rectangular telescopic airbag 504. The surfaces of the air intake pipe and the air inflation pipe are respectively provided with an air intake one-way valve and an air inflation one-way valve. The outer surface of the vertical rod 402 is provided with a reciprocating thread 505, and the surface of the rectangular plate 503 is provided with a threaded hole that is threadedly connected to the outer surface of the reciprocating thread 505.

[0047] Specifically, the rectangular plate 503 can automatically move up and down reciprocally under the action of the reciprocating thread 505 through the rotation of the vertical rod 402.

[0048] In this embodiment, by setting up a cleaning mechanism 500, during the continuous automated film application process achieved by rotating the connecting shaft 2010, the rotation of the vertical rod 402 drives the rectangular plate 503 to move up and down reciprocally under the action of the reciprocating thread 505. That is, when the cylindrical platform 203 rotates 90 degrees, the rectangular plate 503 can move downward and then move upward to reset. During this process, the rectangular plate 503 can squeeze and reset the rectangular telescopic airbag 504. When the rectangular telescopic airbag 504 is squeezed, the air inside the rectangular telescopic airbag 504 can enter the pipe 501 and be sprayed out through the jet nozzle 502 to the surfaces of the soft substrate and the hard substrate facing each other, cleaning them with air and ensuring the cleanliness of the bonding surfaces of the soft substrate and the hard substrate after film application.

[0049] This application also provides a method for applying automated film-applying equipment, including the following steps: S1. Loading of soft and hard substrates: First, the soft substrates are equidistantly bonded to the adhesive conveyor belt 303, and a suitable mold plate 401 is inserted into the rectangular slider 408. The hard substrate is then placed into the mold groove. After that, the three soft substrates are respectively adsorbed onto the upper and lower picking plates 205 and the right picking plate 205 of the cylindrical platform 203. S2. Film application and material handling: First, activate the lowest hydraulic rod 204 to move the lowest material handling plate 205 downwards, allowing the soft substrate on the lowest material handling plate 205 to be applied to the hard substrate on the mold plate 401. Then, activate the vacuum generator 208 to stop the negative pressure adsorption holes 206 on the lowest material handling plate 205 from adsorbing the soft substrate. Next, activate the drive motor 207 to drive the cylindrical platform 203 to rotate 90 degrees, causing the leftmost material handling plate 205 to rotate to the top. Activate the hydraulic rod 204 corresponding to this material handling plate 205 to move it upwards, and activate the vacuum generator 208 on this material handling plate 205 to automatically pick up the soft substrate from the adhesive conveyor belt 303. At the same time, the rightmost material handling plate 205 rotates to the bottom and applies the film, achieving continuous film application.

[0050] Working principle: During the film application process, the equipment first adheres the soft substrate to the outer surface of the adhesive conveyor belt 303 at equal intervals (manual feeding is possible during the application process), and then places the hard substrate in the mold groove on the mold plate 401 (manual loading and unloading is possible during the application process). Next, the drive motor 207 is activated to rotate the connecting shaft 2010. The rotation of the connecting shaft 2010 causes the rotating shaft 202 and the cylindrical platform 203 to rotate. The rotation of the cylindrical platform 203 causes the topmost material-receiving plate 205 to face the adhesive conveyor belt 303. At this point, the hydraulic rod 204 is activated to move the material-receiving plate 205 upwards, and after it adheres to the soft substrate on the adhesive conveyor belt 303, the vacuum generator 208 is activated to achieve... After the soft substrate is effectively adsorbed, the drive motor 207 continues to drive the material-taking plate 205, which has adsorbed the soft substrate, to rotate. Once it is aligned with the hard substrate on the mold plate 401, the hydraulic rod 204 is activated again, causing the material-taking plate 205 to move downwards, allowing the soft substrate to adhere to the surface of the hard substrate. The vacuum generator 208 is then activated, preventing the negative pressure adsorption holes 206 from adsorbing the soft substrate, thus achieving automatic film application. Furthermore, during the rotation of the cylindrical platform 203, the rotation of the connecting shaft 2010 drives the third transmission wheel 307 to rotate. The rotation of the third transmission wheel 307 drives the first transmission wheel 305 to rotate via a transmission belt 308, and the rotation of the first transmission wheel 305 drives the first transmission wheel 305 to rotate via another transmission belt 308. The second drive wheel 306 rotates, which in turn drives the rotating roller 301 to rotate, and the rotating roller 301 in turn drives the conveying roller 302 to rotate, thereby realizing the automatic conveying of the viscous conveyor belt 303, and thus the automatic conveying of the soft substrate. Simultaneously, the rotation of the connecting shaft 2010, under the action of the two first bevel gears 403, drives the vertical rod 402 to rotate. The rotation of the vertical rod 402, under the action of the two second bevel gears 406, drives the horizontal shaft 405 to rotate. The rotation of the horizontal shaft 405, under the action of the two third bevel gears 407, drives the reciprocating screw 404 to rotate, thereby moving the rectangular slider 408, and thus automatically moving the mold plate 401, realizing the automatic conveying of the hard substrate, and thus achieving continuous... The purpose of continuing automated film application is to achieve continuous automated film application through the rotation of the connecting shaft 2010. The rotation of the vertical rod 402 drives the rectangular plate 503 to move up and down reciprocally under the action of the reciprocating thread 505. That is, when the cylindrical platform 203 rotates 90 degrees, the rectangular plate 503 can move down and then move up to reset.
