DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The present invention provides Figure 1-9 A glass surface coating device shown includes a glass coating machine 1 for applying film to glass. A mounting frame 8 is provided in the middle of the glass coating machine 1. A fixed shaft 2 for fixing a glass protective film is provided on the top of the mounting frame 8. Both ends of the fixed shaft 2 are fixed with mounting cylinders 202.

[0035] The top ends of both sides of the mounting frame 8 are respectively provided with an adjustment seat 3 and an end plate 7, the fixed shaft 2 is located between the adjustment seat 3 and the end plate 7, the adjustment seat 3 is provided with a connecting shaft 301 around it through a damping shaft, and a first plug rod 302 is fixedly provided at one end of the connecting shaft 301, one of the first plug rods 302 is inserted into the mounting tube 202 on the corresponding side, and the bottom end of the adjustment seat 3 is movably connected to the mounting frame 8 through a shaft.

[0036] The end plate 7 is fixed on the top of the mounting frame 8, and a threaded push rod 701 is provided on the end plate 7, which passes through the end plate 7 and is connected to the end plate 7 by a thread. A fixed platform 703 is provided at one end of the threaded push rod 701 through a rotating shaft, and a handle is fixed at the other end of the threaded push rod 701. A second plug rod 702 that can be inserted into another mounting tube 202 is fixed at one end of the fixed platform 703, and the cross-sections of the second plug rod 702 and the first plug rod 302 are both rectangular.

[0037] The rolled-up paper tube with the glass protective film is fixed by being sleeved on the outer end of the fixed shaft 2. In the fixed state, the mounting tubes 202 at both ends of the fixed shaft 2 are respectively fixed on the adjustment seat 3 and the end plate 7. The mounting tubes 202 at both ends of the fixed shaft 2 are respectively inserted into the first plug rod 302 and the second plug rod 702, and the adjusting seat 3 is surrounded by connecting shafts 301 and first plug rods 302. When replacing a new glass protective film, before the original glass protective film is used up, another fixed shaft 2 is selected, and the new paper tube with the glass protective film is sleeved and fixed on the outer end of the fixed shaft 2. Then, the mounting tube 202 at one end of the fixed shaft 2 is sleeved on one of the idle ends of the outer end of the adjusting seat 3. The first plug rod 302 is placed on the first plug rod 302. When the original glass protective film is used up, the threaded push rod 701 is rotated to remove the second plug rod 702 from the corresponding mounting tube 202. Then the adjusting seat 3 is rotated to rotate the fixed shaft 2 with the new glass protective film fixed to the position of the original fixed shaft 2 to replace the original fixed shaft 2. Then the threaded push rod 701 is rotated again to insert the second plug rod 702 into the mounting tube 202 at one end of the new fixed shaft 2. In this way, the new fixed shaft 2 is installed to complete the process of replacing the glass protective film. The original fixed shaft 2 is moved away from the top of the mounting frame 8 as the adjusting seat 3 rotates, and then it can be removed from the adjusting seat 3.

[0038] In the process of replacing the glass protective film, the paper tube is fixed on the fixed shaft 2 in advance. When replacing, it is only necessary to rotate the adjustment seat 3 and swap the positions of the two fixed shafts 2. There is no need to remove the old paper tube and install a new one. It is more convenient and quick, and has less impact on the working efficiency of the glass laminating machine 1.

[0039] The glass protective film rolled up on the outer end of the paper tube is fixed on the outer end of the fixed shaft 2, such as Figure 1-4 As shown, the outer end of the fixed shaft 2 is inlaid with multiple hidden chambers 203, the bottom end of the hidden chamber 203 is fixed with two air holes connected to the inside of the fixed shaft 2, the outer end of the fixed shaft 2 is fixed with an air guide tube with a valve, and the fastening block 201 can clamp and fix the paper tube of the rolled protective film from the inside.

[0040] A fastening block 201 is disposed inside the hidden chamber 203 , and two return springs 204 connected to the fastening block 201 are fixedly disposed on the inner wall of the hidden chamber 203 .

[0041] When the glass protective film is not fixed to the outer end of the fixed shaft 2, the fastening block 201 is retracted inside the hidden chamber 203 and does not extend outward. After the paper tube with the glass protective film rolled up is put on the outer end of the fixed shaft 2, the fastening block 201 will be put into the inner side of the paper tube. At this time, air is inflated into the interior of the fixed shaft 2 through the air duct. The air entering the interior of the fixed shaft 2 can enter the hidden chamber 203 through the air vents and push the fastening block 201 to extend outward. After the fastening block 201 is extended, it will be stuck on the inner wall of the paper tube, thereby clamping and fixing the paper tube with the glass protective film rolled up to the outer end of the fixed shaft 2. The movement of the fastening block 201 will also stretch the reset spring 204. After the air inside the fixed shaft 2 is discharged, the reset spring 204 will pull the fastening block 201 to retract back into the hidden chamber 203 so that the paper tube can be removed.

[0042] After applying the film, you need to cut off the glass protective film on the front side of the glass. Figure 2 , 6 As shown in Figures 7 and 8, an upper film cutting roller 4 is provided inside the mounting frame 8. The upper film cutting roller 4 is provided at the rear side of the squeezing roller of the glass laminating machine 1. Both ends of the upper film cutting roller 4 are provided with linear motors. After the film pasting is completed, under the control of the program, the linear motor drives the upper film cutting roller 4 to move downward. The linear motor is provided on the inner wall of the mounting frame 8, and the upper film cutting roller 4 is connected to the mover of the linear motor.

[0043] A lower film cutting roller 6 is provided at the bottom end of the upper film cutting roller 4. After the upper film cutting roller 4 moves downward, it clamps the protective film on the front side of the glass after film lamination. A hidden groove 605 is opened at the outer end of the lower film cutting roller 6, and a film cutting knife 604 is provided inside the hidden groove 605.

[0044] The glass is driven to move by the glass coating machine 1. When it moves to the mounting frame 8, the glass coating machine 1 sticks the glass protective film on the glass surface. The operation of the glass coating machine 1 is automatically controlled by the program. After the film pasting is completed, the glass moves backward and passes between the upper film cutting roller 4 and the lower film cutting roller 6. When the glass passes, the program controls the linear motor to drive the upper film cutting roller 4 to move downward, clamping the uncut glass protective film on the front side of the glass, and with the movement of the glass, the glass protective film also moves accordingly, driving the upper film cutting roller 4 and the lower film cutting roller 6 to rotate. During the movement, the film cutting knife 604 originally hidden in the hidden groove 605 extends outward. Therefore, when the glass protective film is clamped between the film cutting knife 604 and the upper film cutting roller 4, it will be cut off under the action of the film cutting knife 604, thereby disconnecting the protective film pasted on the glass from the unused glass protective film, thereby disconnecting the glass protective film during the movement. The movement of the glass does not need to be paused, so that the glass film pasting work can be carried out continuously with higher efficiency.

[0045] This method of cutting the glass protective film is to use the upper film cutting roller 4 and the lower film cutting roller 6 to replace the traditional cutting structure in the prior art, and the cutting process is automatically controlled by a program.

[0046] Reach upwards to clamp the protective film on the front side of the glass and then cut it off. Figure 2 , 6 As shown in Figures 7 and 8, a central tube 601 is provided inside the lower film cutting roller 6, an airbag 602 is fixedly provided at the outer end of the central tube 601, and a plurality of through holes 607 located inside the airbag 602 are opened at the outer end of the central tube 601, so that the air inside the central tube 601 can enter the airbag 602.

[0047] The outer end of the airbag 602 is provided with a bottom rod 603, and both ends of the bottom rod 603 are fixedly provided with positioning springs 606 fixedly connected to the outer end of the central tube 601. The bottom end of the film cutting knife 604 is fixedly connected to the outer end of the bottom rod 603, and the top end of the film cutting knife 604 is located inside the hidden groove 605.

[0048] Both ends of the center tube 601 extend to both sides of the lower film cutting roller 6 respectively, one end of the center tube 601 is movably connected to the inner wall of the mounting frame 8 through a rotating shaft, an extension tube is arranged inside the center tube 601, and one end of the extension tube is movably connected to the inner wall of the center tube 601 through a sealed bearing.

[0049] The other end of the extension tube is fixedly connected to the inner wall of the mounting frame 8, and an air filling tube is fixedly arranged at the outer end of the extension tube. Under the control of the program, after the glass film is applied, air is filled into the extension tube through the air filling tube.

[0050] When the film cutting knife 604 needs to be extended outward, the program controls the external air to flow into the extension tube through the inflation tube. The air entering the extension tube then enters the central tube 601 and flows into the airbag 602 through the through hole 607. The inflow of air causes the airbag 602 to expand. The expanded airbag 602 pushes the bottom rod 603 away from the central tube 601. The movement of the bottom rod 603 causes the positioning spring 606 to be stretched and pushes the film cutting knife 604 originally hidden in the hidden groove 605. After the hidden groove 605 is extended, the glass protective film can be cut off. After the cutting work is completed, the air is discharged, the airbag 602 shrinks, and the bottom rod 603 that has lost its support moves back under the elastic force of the positioning spring 606 and drives the film cutting knife 604 back to its original position.

[0051] After applying the film, you need to remove the bubbles on the glass protective film, such as Figure 2 , 9 As shown, a debubble assembly 5 is provided at the rear side of the mounting frame 8 , and the debubble assembly 5 includes a mounting shaft 502 , and a detachable scraper 501 is provided at the outer end of the mounting shaft 502 .

[0052] Both ends of the mounting shaft 502 are provided with mounting plates 504 through a rotating shaft, and the mounting plates 504 are fixedly arranged on the rear side of the mounting frame 8. Both ends of the mounting shaft 502 are provided with torsion springs 503, and one end of the torsion spring 503 is fixedly connected to the mounting plate 504 on the corresponding side. Two annular protrusions are fixedly arranged on the outer end of the mounting shaft 502, and the other end of the torsion spring 503 is fixedly connected to the annular protrusion on the corresponding side.

[0053] The glass after film application is moved to the debubble assembly 5 under the transportation of the glass laminating machine 1. At this time, the torsion spring 503 is in a tightened state. The elastic force of the torsion spring 503 drives the installation shaft 502 to rotate and enables the bottom end of the scraper 501 to apply force to the moving glass surface. As the glass moves, the installation shaft 502 can scrape off the bubbles on the surface of the glass protective film, thereby removing bubbles. Compared with squeezing, scraping the surface of the glass protective film with the scraper 501 can achieve a better debubble effect.

[0054] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
