Description

Technical Field

[0002] The glass coating device is mainly used to form a thin film on the glass surface, which is mainly used to improve the optical properties of the glass, such as adjusting the light transmittance and adjusting the light color, etc. It can also be used to improve the thermal insulation of the glass, and has thermal insulation and heat insulation effects. There are many existing glass coating methods, such as vacuum coating; in the evaporation process of physical vacuum coating, the evaporating material generally evaporates at a fixed position in the vacuum chamber, and the material atoms or molecules will expand radially outward with the evaporation source as the center. In this case, the glass surface area closer to the evaporation source will receive more evaporation material atoms or molecules, resulting in a thicker film layer in this area, while the area farther away from the evaporation source will receive fewer atoms or molecules, and the film layer will be thinner, resulting in uneven glass coating.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] The embodiments provided by the present invention will be described in detail below: like Figures 1 to 4 As shown, a glass coating device with a uniform film layer comprises a coating device 1, a control panel 3 is arranged on the outer surface of the coating device 1, an air intake pipe 8 for balancing the air pressure of the coating device 1 and the external space is arranged on the outer side of the coating device 1, a solenoid valve is arranged inside the air intake pipe 8, two door panels 2 are horizontally slidably connected to the coating device 1, and the two door panels 2 are fixedly connected with vertically symmetrical sliding bars 21 on one side close to the coating device 1, and the coating device 1 is provided with vertically symmetrical sliding grooves 22 on one side close to the door panel 2, and the sliding bars 21 slide inside the sliding grooves 22, and the side wall of the coating device 1 is fixedly connected with a first spring 23, and the end of the first spring 23 away from the coating device 1 is fixedly connected to the door panel 2, so as to assist the two door panels 2 to close after approaching each other, and a coating component for moving the evaporated coating material is arranged inside the coating device 1; like Figure 2 and Figures 7 to 9 As shown, the coating assembly includes a fixed rod 71 fixedly connected to the inside of the coating equipment 1, and two guide rods 72 are fixedly connected to the outer surface of the fixed rod 71 on the side away from the door panel 2. A motor 73 is fixedly connected to the middle part of the fixed rod 71, and a bidirectional screw rod 74 is fixedly connected to the output shaft of the motor 73. The outer surface of the bidirectional screw rod 74 is provided with a cross thread groove, and a moving frame 75 is slidably connected to the guide rod 72. The top of the moving frame 75 is fixedly connected to a vacuum evaporator 76, and the bottom of the moving frame 75 is rotatably connected to a slider 77, and the bottom of the slider 77 slides inside the thread groove of the bidirectional screw rod 74.

[0018] like Figures 2 to 6As shown, a vacuum assembly is arranged between each door panel 2 and the coating equipment 1, and the vacuum assembly includes two fixed plates 41 respectively fixedly connected to each door panel 2, and a sealing cover 42 is fixedly connected to the fixed plate 41, and a one-way valve plate 43 is arranged on the top of the sealing cover 42. The one-way valve plate 43 is used to facilitate the discharge of gas during exhaust, and an exhaust pipe 47 corresponding to the position of the one-way valve plate 43 is fixedly connected to the top of the sealing cover 42. Two ventilation grooves 44 corresponding to the position of the sealing cover 42 are opened on the coating equipment 1, and a vacuum pump 45 is arranged inside the ventilation groove 44. Two sealing gaskets 49 corresponding to the position of the sealing cover 42 are fixedly connected to the outer surface of the coating equipment 1, and a side of the sealing cover 42 away from the fixed plate 41 is in contact with the sealing gasket 49. When the sealing cover 42 and the sealing gasket 49 are in contact with each other, the ventilation groove 44 is blocked to prevent external air from entering the interior of the coating equipment 1.

[0019] like Figures 10 to 12 As shown, a moving assembly for clamping the movable door and window glass is arranged inside the coating device 1, and the moving assembly includes a moving plate 62 located inside the coating device 1, and rolling grooves 61 are symmetrically opened inside the coating device 1. Electric wheels 63 are arranged at the bottom of the moving plate 62, and the electric wheels 63 roll inside the rolling grooves 61. A movable bottom frame 66 is fixedly connected to the upper surface of the moving plate 62, and the movable bottom frame 66 is composed of a groove rod and a sleeve. A second spring 67 is fixedly connected inside the sleeve of the movable bottom frame 66, and a tray frame 68 is fixedly connected to the top of the second spring 67. The tray frame 68 is composed of a cylindrical tube and a tray, and the cylindrical tube of the tray frame 68 slides vertically on the movable bottom frame 66. The tray rack 68 has a sleeve, and clamping grooves are provided on both sides of the tray. Push-pull rods 69 are hinged on both sides of the cylindrical tube of the tray rack 68. The push-pull rods 69 are hinged on the end away from the tray rack 68. The rack 610 slides horizontally in the slot rod of the movable base frame 66. The slot rod of the movable base frame 66 is rotatably connected with a gear 611, and the gear 611 and the rack 610 are engaged with each other. Two sliding frames 612 are symmetrically slidably connected to the slot rod of the movable base frame 66. The top lower surface of the sliding frame 612 is fixedly connected with a convex tooth 613, which is engaged with the gear 611. The sliding frame 612 is fixedly connected with a limit plate 614, and the limit plate 614 is made of rubber.

[0020] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: the door panel 2 is in a closed state, the first spring 23 is in an unstretched state, the tray frame 68 is not squeezed, the second spring 67 is not compressed, and the two sliding frames 612 are at the outermost sides of the slot rods of the movable bottom frame 66.

[0021] The working status is: Opening and closing of the door panel 2: When it is necessary to store or take the door and window glass that needs to be coated into the coating equipment 1, the staff pulls the door panel 2 outward so that the door panel 2 slides in the slide groove 22 through the sliding bar 21, so that the door panel 2 can move horizontally to both sides. When the door panel 2 moves to both sides, the first spring 23 will be stretched, thereby opening the door panel 2.

[0022] Afterwards, the electric wheel 63 is powered on and started by manually controlling the controller. The electric wheel 63 rolls in the rolling groove 61, and then the electric wheel 63 drives the movable plate 62 to move toward one side of the door panel 2 inside the coating equipment 1. When the movable plate 62 moves close to the door panel 2, the door panel 2 can be manually released. At this time, under the action of the first spring 23, the door panel 2 will slide toward the middle, but it will resist the side of the movable plate 62. At this time, the staff will place the door and window glass on the tray of the tray rack 68. Under the action of the gravity of the door and window glass, the tray rack 68 will be pressed down, so that the cylindrical tube of the tray rack 68 moves downward in the sleeve of the movable base frame 66 and compresses the second spring 67. During the downward movement of the cylindrical tube of the tray rack 68, it will pass through The push-pull rod 69 pushes the rack 610 to move to both sides in the groove rod of the movable base frame 66, and the rack 610 drives the gear 611 meshing with it to rotate, and the gear 611 drives the convex tooth 613 meshing with it and the sliding frame 612 to move to one side of the tray frame 68 on the groove rod of the movable base frame 66, and the sliding frame 612 drives the limit plate 614 to converge to the middle, so that the limit plate 614 can position the door and window glass on the tray to prevent the door and window glass from shaking when it is moved or pushed into the coating equipment 1, thereby keeping the door and window glass stable during the coating process, and the limit plate 614 is only limited to the two sides of the door and window glass, and will not block the upper surface of the glass, to ensure that the coating material can effectively fall on the glass surface.

[0023] In addition, when the limit plate 614 converges toward the middle, it can enter the clamping groove on the tray rack 68, and thus can effectively position smaller door and window glasses, thereby enabling the limit plate 614 to position door and window glasses of different sizes and increasing the positioning range of the limit plate 614.

[0024] At the same time, the staff can place the coating material on the movable frame 75, first control the motor 73 through the control panel 3 to drive the bidirectional screw rod 74 to rotate, and the threaded groove on the bidirectional screw rod 74 drives the slider 77 to move and then drives the movable frame 75 to slide back and forth on the guide rod 72. When the movable frame 75 moves, it drives the vacuum evaporator 76 to move to the side close to the door panel 2. At this time, the control panel 3 controls the motor 73 to stop driving the bidirectional screw rod 74 to rotate. At this time, the vacuum evaporator 76 stops on the side close to the door panel 2. The staff can evenly sprinkle the powdered coating material on the vacuum evaporator 76 to avoid the problem that the existing vacuum evaporator 76 is in a fixed position and it is inconvenient to place the coating material. In addition, it can also reduce the need for manual penetration into the coating equipment 1 to place the coating material, thereby avoiding the contaminants brought into the coating equipment 1 when manual penetration into the coating equipment 1, further avoiding contamination of the internal space of the coating equipment 1, and also avoiding the influence of contaminants on the coating of door and window glass.

[0025] The moving component drives the door and window glass into the coating equipment 1; further, the electric wheel 63 is manually controlled to rotate in the opposite direction through the control panel 3, and the electric wheel 63 drives the moving plate 62 to move inside the coating equipment 1 toward the side away from the door panel 2. At this time, the moving plate 62 drives the door and window glass positioned by the limiting plate 614 thereon to move toward the inside of the coating equipment 1. When the door and window glass is completely transported to the inside of the coating equipment 1, the moving plate 62 will also gradually move away from the door panel 2. At this time, under the elastic reset action of the first spring 23, the two door panels 2 will be pulled closer to each other, and the door panel 2 will move horizontally toward the middle under the action of the sliding bar 21 sliding in the sliding groove 22. At this time, the door panel 2 achieves the effect of automatic closing.

[0026] At this time, the vacuum pump 45 is started through the control panel 3, and the vacuum pump 45 will gradually draw out the gas inside the coating equipment 1, so that the air inside the coating equipment 1 is discharged to the outside from the exhaust pipe 47, so that the interior of the coating equipment 1 tends to be in a vacuum state. At this time, the vacuum evaporator 76 is started through the control panel 3, and then the coating material on the movable frame 75 is evaporated, so that the coating material gradually evaporates or sublimates to form gaseous particles. The coating material of the gaseous particles falls onto the surface of the door and window glass with basically no collision, and the coating material is continuously accumulated on the door and window glass to form a continuous film.

[0027] Uniform coating of coated components: After the motor 73 is started by controlling the control panel 3, it drives the bidirectional screw rod 74 to rotate. The threaded groove of the bidirectional screw rod 74 drives the slider 77 to move, thereby causing the movable frame 75 to reciprocate on the guide rod 72. The movable frame 75 drives the vacuum evaporator 76 to perform horizontal reciprocating motion inside the door panel 2, thereby enabling the vacuum evaporator 76 to move inside the coating device 1 to evaporate the coating material, and further allowing the coating material to evaporate evenly inside the coating device 1. Compared with the existing method of evaporating the coating material at a fixed position, this avoids the problem that the gaseous particles formed by the coating material cannot evenly fill the internal space of the coating device 1, thereby preventing the problem of unevenness when the gaseous particles are deposited on the glass surface, thereby ensuring a uniform coating effect on the door and window glass.

[0028] After the coating is completed, the solenoid valve inside the air intake pipe 8 is controlled by the control panel 3 so that the solenoid valve is opened. Under the action of atmospheric pressure, the external air will enter the interior of the coating equipment 1 from the air intake pipe 8, thereby making the air pressure of the coating equipment 1 and the external air pressure tend to be balanced. At this time, the door panel 2 can be smoothly opened to take out the coated door and window glass.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
