Description

Technical Field

[0001] The utility model relates to the field of glass coating, in particular to a coating unit and a vertical double-sided coating device. Background Art

[0002] There is a lot of cross-operation during the installation and transportation of glass, and it is often contaminated by materials such as cement and lime. It needs to be cleaned after installation, which reduces efficiency and increases labor costs. Therefore, after the glass is processed, a layer of plastic film is attached to its inner and outer surfaces to prevent the glass from being contaminated. When laminating, the produced glass is transported to the laminating area and placed on the corresponding laminating equipment for lamination, which increases the glass production process and reduces production efficiency.

[0003] In the prior art, in order to improve production efficiency, a vertical glass coating equipment is provided, which includes a loading conveyor belt, a coating unit, a film cutting unit and a unloading conveyor belt. The coating unit and the film cutting unit are arranged on a bracket. A conveyor belt is arranged at the bottom of the bracket and can be connected with the loading and unloading conveyor belts. The loading conveyor belt and the unloading conveyor belt are arranged on both sides of the lower part of the bracket. The coating unit includes a film roll rotatably installed by a rotating shaft. The coating unit is arranged at the loading end of the bracket. The film cutting unit includes a cutting knife module that moves up and down and is arranged at the unloading end of the bracket. When a new batch of glass is coated, the first piece of glass enters the bracket, the film roll is tangent to the glass, and the end of the film is manually pressed against the end of the first piece of glass (manual positioning). The conveyor belt is automatically transported, and the movement of the glass drives the film roll to rotate. The film is continuously pulled out and pressed on the glass under the action of the film roll to achieve continuous coating of different glasses. When the glass moves to the film cutting unit, the conveyor belt stops conveying, and the cutter module cuts the film from top to bottom (the film cutting position is 1cm-5cm away from the edge of the glass). The conveyor belt stops after moving the set distance, and the cutter module cuts the film on the ends of adjacent glasses from bottom to top; the conveyor belt works intermittently to achieve coating and cutting of multiple glasses. When the glass enters the unloading conveyor belt, the film between the two glasses is torn off manually to achieve unloading; this technical solution can be connected to the upstream glass production line by the loading conveyor belt, eliminating the turnover conveyor, and the film laminating unit, the film cutting unit and manual cooperation are used to achieve film pasting, thereby improving production efficiency and reducing manpower labor.

[0004] Although the above technical solution improves efficiency and reduces manual labor, during the laminating and cutting process, on the one hand, there is excess film between two adjacent pieces of glass, which needs to be manually torn off. After each shutdown and restart of the device, the first piece of glass in a new batch needs to be manually positioned, which affects the laminating accuracy. On the other hand, since the film roll is passively rotated by the glass to realize film discharge, it is easy to cause stretching of the film. Since the glass transportation is not stable, the stretching effect is uneven, which is easy to wrinkle and produce bubbles, resulting in poor laminating quality. Utility Model Content

DETAILED DESCRIPTION

[0031] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent. Specific implementation method 1

[0033] like Figures 1 to 4As shown, this specific embodiment provides a coating unit, including a mounting seat 1, a film loading assembly 2, a coating roller 3, a film cutting assembly 4, and an electrostatic positioning assembly 9. The film loading assembly 2 is arranged on the mounting seat 1, and the film loading assembly 2 is used to install a film roll 7. The film loading assembly 2 can drive the film roll 7 to rotate, and the film loading assembly 2 includes a film discharge motor 201; the coating roller 3 is rotatably arranged on the mounting seat 1, and the coating roller 3 is connected to the coating motor 5 through a belt transmission assembly, and the coating roller 3 is arranged parallel to the film roll 7; the electrostatic positioning assembly 9 is used to make the film have static electricity, and the film is discharged from the film loading assembly 2 and reaches the coating roller 3 through the electrostatic positioning assembly 9; the film cutting assembly 4 includes a knife holder 402, which is reciprocally movably arranged on the mounting seat 1 and is located at the rear side of the coating roller 3 along the conveying direction of the glass to be coated. 2 can move away from and approach the coating roller 3. A cutter module 401 is arranged on the knife holder 402. The cutter module 401 can cut the film close to the outer cylindrical surface of the coating roller 3; the cutter module 401 can adopt an electric thermal resistance wire or a blade. When the electric thermal resistance wire is adopted, the cutter module 401 does not need to move up and down reciprocatingly. It only needs to set the length of the electric thermal resistance wire to be greater than the maximum coating height. In this specific embodiment, the cutter module 401 adopts a film cutting blade. The cutter module 401 can reciprocate in the vertical direction. The knife holder 402 is connected to the knife seat through a guide rail. The film cutting blade is installed on the knife seat through bolts. The knife seat is connected to the piston of the film cutting cylinder 403. The film cutting cylinder 403 is arranged on the knife holder 402. The blade of the cutter module 401 can contact with the outer cylindrical surface of the coating roller 3 to cut the film.

[0034] The specific embodiment actively drives the film roll 7 to rotate by the film discharge motor 201 and the coating motor 5, replacing the mechanical coupling method in the prior art in which the movement of the glass to be coated drives the film roll 7 to passively release the film. The film discharge speed of the film can be controlled to be synchronized with the moving speed of the glass, which greatly eliminates the problem of film looseness or excessive tightness caused by passive film release, and avoids wrinkling or bubbles after lamination. Under the synergistic effect of the coating roller 3, the lamination quality of the film and the glass is further improved. Moreover, the electrostatic adsorption of the end of the film by the coating roller 3 can realize automatic positioning of the starting end of the coating, and the positioning of the ending end of the coating can be realized by the film cutting component 4, so as to effectively control the coating length and avoid excess film between two adjacent glasses when discharging. Manual positioning and manual film tearing are eliminated, and basically fully automatic lamination is realized, which improves the lamination efficiency and saves materials.

[0035] like Figure 3As shown, in this specific embodiment, the electrostatic positioning component 9 can adopt the following specific structure: the electrostatic positioning component 9 includes an electrostatic rod 902 and a metal rod 901, the electrostatic rod 902 is vertically arranged between the film loading component 2 and the coating roller 3, the height of the electrostatic rod 902 is not less than the height of the coating roller 3, the metal rod 901 and the electrostatic rod 902 are respectively arranged on both sides of the film, and the metal rod 901 is grounded. When the electrostatic rod 902 is powered by high voltage, the film obtains static charge through corona treatment; in this specific embodiment, the coating roller 3 is made of an insulating material such as rubber. Since the dielectric constant of glass is higher than that of the rubber coating roller 3, the polarization effect generated is strong. The charged film will induce a stronger polarization charge on the glass surface through the electric field, forming a more significant Coulomb attraction, so when the coating roller 3 is tangent to the glass, the film is more easily and evenly adhered to the glass.

[0036] like Figure 4 As shown, in this specific embodiment, the film loading component 2 can adopt the following specific structure: the film loading component 2 includes an upper film seat 203 and a lower film seat 204, the lower film seat 204 is rotatably arranged at the bottom of the mounting seat 1 through a bearing, the upper film seat 203 is rotatably arranged on the lifting seat 202 through a bearing, the lifting seat 202 is reciprocally arranged on the mounting seat 1 through a guide rail, the lifting seat 202 is connected to a film loading cylinder 205, the film loading cylinder 205 is arranged on the mounting seat 1, the film discharging motor 201 is arranged on the lifting seat 202, the film discharging motor 201 is connected to the central axis of the upper film seat 203, and the upper film seat 203 The upper and lower film seats 203 and 204 can respectively abut against the two ends of the film roll. In the present specific embodiment, the upper and lower film seats 203 and 204 are both provided with limiting bosses, which can extend into the two ends of the film roll 7. When installing the film roll 7, the film roll 7 is first placed on the lower film seat 204, and the film loading cylinder 205 retracts to drive the upper film seat 203 to descend and press tightly on the film roll 7. When the film output motor 201 rotates, the film roll 7 can be driven to rotate under the drive of friction to realize film output. The film roll 7 is installed by pressing the upper and lower film seats 203 and 204 up and down, which can effectively prevent the film roll 7 from slipping and further avoid the film from being stretched.

[0037] like Figure 3As shown, since the film roll 7 is constantly rotating to discharge the film, its diameter is constantly decreasing. If its rotation speed remains unchanged, the film discharge line speed will be reduced, and it will not be able to keep pace with the glass conveying speed, and the stability of the coating quality cannot be guaranteed. Therefore, in this specific embodiment, a distance sensor 11 is also provided on the mounting seat 1. The distance sensor 11 is used to detect the diameter of the film roll 7. The distance sensor 11 sends the detected distance from the surface of the film roll 7 back to the controller. The controller calculates the diameter of the film roll 7 based on the initial distance, and then redetermines the rotation speed of the film roll 7 based on the glass conveying speed, and then adjusts the rotation speed of the film discharge motor 201, which can ensure the synchronization of the film discharge line speed and the glass conveying speed, and greatly avoid the change in the diameter of the film roll 7. The stretching effect on the film.

[0038] To further improve the automation level and coating accuracy, in this specific embodiment, the film output motor 201 adopts a servo motor, and the coating motor 5 adopts a servo motor; the servo motor can obtain the film output amount to ensure the accuracy of the coating size on the glass and avoid affecting the subsequent framing.

[0039] like Figure 4 As shown, as a preferred embodiment, the film cutting assembly 4 also includes a film pressing roller 10, which is vertically arranged on the mounting seat 1, and the film pressing roller 10 is rotatably arranged on the mounting seat through bearings. The film pressing roller 10 and the knife holder 402 are arranged on the same side of the coating roller 3, and are located on the side of the knife holder 402 away from the glass. The axial dimension of the film pressing roller 10 is not less than the axial dimension of the coating roller 3, which can ensure that the film side is pressed throughout the process, the outer cylindrical surface of the film pressing roller 10 can be pressed against the outer cylindrical surface of the coating roller 3, and the film pressing roller 10 can reciprocate on the mounting seat 1, and the film pressing roller 10 is connected to the mounting seat 1 through a guide rail. The laminating roller 10 is also connected to a laminating cylinder 405, which is arranged on the mounting seat 1. The laminating roller 10 is driven by the laminating cylinder 405 to achieve reciprocating movement. During lamination, the laminating roller 10 is always pressed against the laminating roller 3 with the film adsorbed thereon. When the film roll 7 needs to be replaced, the laminating roller 10 is reset under the drive of the laminating cylinder 405. The laminating roller 10 can ensure that the cut film is always pressed on the laminating roller 3, thereby preventing the film from moving and wrinkling under the action of the cutting module 401, and further preventing the film from being adsorbed and folded under the action of static electricity, and being unable to be adsorbed flatly on the laminating roller 3.

[0040] It can be understood that the film discharging motor 201, the film laminating motor 5, the distance measuring sensor 11, the film cutting cylinder 403, the film loading cylinder 205, the knife feeding cylinder 404, and the film pressing cylinder 405 are all electrically connected to the controller.

[0041] The working process of this laminating unit is:

[0042] When lamination is required, the laminating motor 5 and the film discharging motor 201 rotate simultaneously to discharge the film. After the film is discharged from the film loading component 2, it passes through the electrostatic positioning component 9 to reach the laminating roller 3 and is adsorbed on the laminating roller 3. At this time, the laminating roller 3 is always pressed against the film pressing roller 10, and the film pressing roller 10 can rotate under the drive of the laminating roller 3; when the glass is conveyed to the laminating roller 3, the outer circumference of the laminating roller 3 begins to be tangent to the glass surface, driving the film to move and making the film cover the glass surface; when it is determined that the film discharge reaches the set length, the glass stops conveying, and the cutting module 401 moves toward the laminating roller 3. After it is in place, the cutting module 401 moves up and down to cut the film. After cutting the film, the knife frame 402 is reset, and one end of the film that is cut (the end connected to the film roll 7) is electrostatically attached to the laminating roller 3, and the other end of the film that is cut, as the glass continues to move, is attached to the glass under the action of the laminating roller 3 (the laminating roller 3 and the film loading component 2 continue to rotate).

[0045] This specific embodiment can achieve double-sided lamination by providing two lamination units, thereby improving the lamination efficiency.

[0046] like Figure 5 and Figure 6As shown, due to the different thicknesses of different types of glass products, in order to improve the applicability of the device, the two mounting seats 1 can be movably arranged on the bracket 15, and the moving direction of the mounting seat 1 is perpendicular to the glass to be coated; specifically, the bracket 15 includes a base 1502, on which two support frames 1501 are relatively arranged, and the two mounting seats 1 are respectively installed on the lower part of the corresponding support frame 1501 through a slide rail, and the two mounting seats 1 are provided with a driving motor 6, and the driving motor 6 is connected to a gear 8, and the gear 8 is meshed with the rack on the support frame 1501; driven by the driving motor 6, the spacing between the two coating units can be adjusted according to the size of the glass product to ensure the coating quality. It can be understood that the motor + lead screw method can also be used to drive the mounting seat 1 to move and adjust the spacing between the front and rear coating units, that is, the motor is arranged on the support frame 1501, the lead screw is rotatably arranged on the support frame 1501, and a moving seat is arranged on the lead screw, and the moving seat is connected to the mounting seat 1.

[0047] In this specific embodiment, a proximity switch is provided at the loading end of the bracket 15, and the proximity switch can sense the position of the glass to be coated; at the same time, the coating conveyor belt 14 on the bracket 15 is driven by a servo motor, and the position of the glass can be accurately known; this device includes a controller, and the proximity switch, the loading conveyor belt 12, the coating conveyor belt 14 and the unloading conveyor belt 13 are all electrically connected to the controller.

In addition, the coating roller 3 can absorb the end of the film to realize automatic positioning of the starting end of the coating, and the film cutting component 4 can realize positioning of the end end of the coating, effectively controlling the coating length, avoiding excess film between two adjacent glasses when discharging, eliminating manual positioning and manual film tearing, basically realizing fully automatic lamination, and improving lamination efficiency.
