Description

Technical Field

[0001] The invention belongs to the technical field of laminating, and in particular relates to a glass upper and lower laminating machine. Background Art

[0002] The automatic glass laminating machine is a device specially used to automatically cover the protective film (usually a plastic film) on the glass surface. It is widely used in glass production, processing, storage and transportation, and can effectively protect the glass surface from scratches, pollution, dust, oil and other external damage.

[0003] The Chinese utility model patent document with announcement number CN222875314U discloses a surface coating device for glass production, and specifically discloses a frame, wherein an electrostatic generator is fixedly connected to the outer wall of one side of the frame, and a cable is connected to the outer wall of one side of the electrostatic generator, and the outer walls of both ends of the cable are fixedly connected to mounting bases, and an electrostatic rod is installed on the outer wall of one side of the mounting base; a double-headed cylinder is fixedly connected to the outer wall of one side of the frame, and the piston rods at both ends of the double-headed cylinder are fixedly connected to the connecting base, and a film cutting knife is welded to the outer wall of the connecting base. Whenever the upper and lower surfaces of the glass are coated, the piston rods at both ends of the double-headed cylinder are contracted to control the film cutting knives on the two connecting bases to move closer to each other, intermittently completing the film cutting operation, so that its length just matches the size of the glass, and can better complete the glass surface coating operation.

[0004] In the technical literature disclosed in the above patent, after the upper and lower layers of glass are coated, a double-headed cylinder is used to drive the upper and lower film cutting knives to complete the cutting of the upper and lower protective films. Since the film is cut by the up and down movement of the film cutting knife, the contact area between the film cutting knife and the film is large. Therefore, the edge of the film cutting knife needs to be kept sharp. If the film cutting knife is worn or blunt, the film cannot be cut smoothly, and it will cause the film to be pulled and deformed. Not only can the flatness of the film and the glass end surface not be guaranteed, but also the coating effect is poor. Summary of the Invention

[0005] The purpose of the present invention is to provide a glass upper and lower laminating machine, which solves the problem in the prior art that after the glass is double-sidedly laminated, the film will be pulled during the cutting process, resulting in film deformation and poor laminating effect.

[0017] Furthermore, a sensor is provided at the output end of the first conveying device.

[0018] Furthermore, the glass upper and lower laminating machine also includes a support frame, which is located above the laminating device. One of the film unwinding mechanisms is arranged on the support frame, and the other film unwinding mechanism is arranged on the bottom side of the second conveying device.

[0019] Furthermore, the film unwinding mechanism includes two film roll racks and a film splicing mechanism; the film roll rack is used to place the film roll, and the film splicing mechanism includes a base, a lower hot pressing mold, a mounting frame, a lower pressing mechanism, an upper hot pressing mold, a lower film cutting knife and an upper film cutting knife; the lower hot pressing mold and the lower film cutting knife are arranged on the base; the mounting frame is arranged above the base, the lower pressing mechanism and the upper film cutting knife are arranged on the mounting frame, and the upper hot pressing mold is arranged at the bottom end of the lower pressing mechanism.

[0021] The above one or more technical solutions in the glass upper and lower laminating machine provided by the embodiment of the present invention have at least the following technical effects:

[0022] Film rolls are mounted on the upper and lower film unwinding mechanisms. The free ends of the film rolls pass around the deflection roller and then pass between the first active roller and the first driven roller. A glass sheet can be placed on the conveying surface of the first conveyor device, which conveys the glass toward the second conveyor device. During the conveying process, the glass passes between the first active roller and the first driven roller, and the upper and lower films are pressed against the upper and lower surfaces of the films. The first active roller and the first driven roller simultaneously hold and convey the glass, allowing it to pass between the second driven roller and the second active roller. The second driven roller and the second active roller press the film on the glass a second time, while simultaneously conveying the glass toward the conveying surface of the second conveyor device. After the glass leaves the channel formed between the first active roller and the first driven roller, the second driven roller, the second active roller, and the second conveying device stop operating until the next piece of glass is pushed between the first active roller and the first driven roller. The two pieces of glass can be pushed at the same time. When the connection position formed by the film connecting the two pieces of glass is conveyed to the guide groove position of the guide mechanism, the two pieces of glass stop conveying at the same time, and the translation mechanism of the die cutting mechanism drives the film cutting knife to translate in the guide groove, thereby cutting the corresponding film.

[0023] Since the film cutter moves horizontally within the guide groove to cut the film, the instantaneous contact area between the film and the film cutter can be reduced, allowing the film cutter to smoothly cut the film, avoiding problems such as pulling on the film and causing deformation, ensuring that the film can be stably pressed against the glass surface, and the flatness of the film cut can be guaranteed after the film is cut. In addition, during the film coating process, the spacing between the glass can be effectively controlled, avoiding the problem of film waste caused by uneven spacing between the glass during the coating process, and the problem of the film remaining on the glass after the film is cut being consistent.

Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0038] In one embodiment of the glass upper and lower laminating machine of the present invention, lamination of the upper and lower surfaces of the glass can be achieved, and continuous lamination of the glass can be maintained, as well as lamination stability and flatness of the film after cutting.

[0039] For details, please refer to Figure 1 The glass upper and lower laminating machine of this embodiment includes a first conveying device 100, a second conveying device 200, a laminating device 300, and a film unwinding mechanism 400. The first conveying device 100 and the second conveying device 200 are arranged in front and behind each other along the conveying direction. The first conveying device 100 and the second conveying device 200 both include a conveying surface, and the laminating device 300 is arranged between the first conveying device 100 and the second conveying device 200. Specifically, the glass to be coated can be placed on the conveying surface of the first conveying device 100, and the first conveying device 100 conveys the glass plate to the second conveying device 200. During the conveying process, the glass passes through the laminating device 300, and the laminating device 300 presses a thin film on the upper and lower surfaces of the glass.

[0040] Reference Figures 5 to 8The laminating device 300 includes a laminating roller assembly 310, a conveying roller assembly 320, a film cutting mechanism 330, and a guide mechanism 340. The laminating roller assembly 310 is located closer to the output end of the first conveying device 100. The laminating roller assembly 310 includes a first driven roller 311 and a first driving roller 312 arranged vertically, a first drive motor 313 connected to the first driving roller 311, and two sets of steering rollers 314 arranged vertically. The free end of the film roll on the film unwinding mechanism 400 passes around the steering roller 314 and passes between the first driven roller 311 and the first driving roller 312, thereby forming a V-shaped inlet for the upper and lower films. When the glass is input from the first conveying device 100 to the space between the first driven roller 311 and the first driving roller 312, the film can be smoothly pressed against the glass surface.

[0041] Reference Figures 5 to 7 The conveying roller assembly 320 is arranged closer to the input end of the second conveying device 200. The conveying roller assembly 320 includes a second driven roller 321 and a second active roller 322 arranged above and below, and a second drive motor 323 connected to the second active roller 322. When the glass is conveyed between the second driven roller 321 and the second active roller 322, the second driven roller 321 and the second active roller 322 hold the glass, and the second drive motor 323 drives the second active roller 322 to rotate, thereby driving the glass to continue to be conveyed.

[0042] Reference Figure 7 and Figure 8 The guide mechanism 340 is provided between the laminating roller assembly 310 and the conveying roller assembly 320. The guide mechanism 340 includes two guide plates 341 provided one above the other, a gap being formed between the two guide plates 341, and a guide groove 342 being provided on the guide plates 341.

[0043] Reference Figure 5 and Figure 7 The film cutting mechanism 330 comprises two groups, one located above the guide mechanism 340 and the other located below it. The die cutting mechanism 340 includes a translation mechanism 331 and a film cutting knife 332. The film cutting knife 332 is connected to the translation mechanism 331, which drives the film cutting knife 332 to move horizontally along the corresponding guide groove 342. Furthermore, the die cutting mechanism 330 includes a lifting drive 333, on which the film cutting knife 332 is mounted. During die cutting, the lifting drive 333 drives the die cutting knife 332 down to one side of the film.

[0044] Reference Figure 1There are two sets of film roll unwinding mechanisms 400, one set on the upper side of the laminating device 300, and the other set on the lower side of the laminating device 300. The film roll unwinding mechanisms 400 are used to place, position, and support the film roll. The free end of the film roll passes around the deflection roller and then passes between the first active roller and the first driven roller.

[0045] Specifically, when laminating glass, the upper and lower film laminating machine of this embodiment installs film rolls on the upper and lower film unwinding mechanisms 400. The free end of the film roll passes around the deflection roller 314 and then passes between the first driving roller 312 and the first driven roller 311. A glass sheet can be placed on the conveying surface of the first conveyor device 100, which conveys the glass toward the second conveyor device 200. During the conveying process, the glass passes between the first driving roller 312 and the first driven roller 311. The upper and lower films are pressed against the upper and lower surfaces of the film by the first driving roller 312 and the first driven roller 311. Simultaneously, the glass is held and conveyed by the first driving roller 312 and the first driven roller 311, allowing the glass to pass between the second driven roller 321 and the second driving roller 322. The second driven roller 321 and the second driving roller 322 apply a second pressure to the film on the glass while conveying the glass toward the conveying surface of the second conveyor device 200. After the glass leaves the passage formed between the first active roller 312 and the first driven roller 311, the second driven roller 321, the second active roller 322, and the second conveying device 200 stop operating until the next glass is pushed between the first active roller 312 and the first driven roller 311. The two glasses can then be pushed simultaneously. When the connection point formed by the film connecting the two glasses is conveyed to the guide groove 342 of the guide mechanism 340, the two glasses stop conveying simultaneously. The translation mechanism 311 of the die cutting mechanism 330 drives the film cutting knife 332 to translate within the guide groove 342, thereby severing the corresponding film. Since the film cutting knife 332 translates within the guide groove 342 to cut the film, the instantaneous contact area between the film and the film cutting knife 332 is reduced, allowing the film cutting knife 332 to smoothly cut the film, avoiding problems such as pulling on the film and causing deformation, ensuring that the film can be stably pressed against the glass surface, and maintaining the flatness of the cut after the film is cut. In addition, during the film coating process, the spacing between the glasses can be effectively controlled, avoiding the problem of film waste due to unequal glass spacing during the coating process, and the problem of consistent length of film retained on the glass after the film is cut.

[0046] Further, refer to Figure 8In order to increase the stability when cutting the film and avoid problems such as the film moving and dislocating during the cutting process, the guide mechanism 340 of this embodiment also includes a lifting mechanism 343, and lifting mechanisms 343 are also provided at both ends of the two guide plates 341. When the film is cut, the lifting mechanism 343 drives the guide plates 341 to move, so that the guide plates 341 are pressed against the glass surface and the film is pressed tightly against the surface of the glass, avoiding the problem of film displacement during the film cutting process.

[0047] Further, refer to Figure 8 The guide groove 342 forms two limiting portions on the guide plate. An air channel 344 is provided within the limiting portion. Air channel 344 is provided with a plurality of air holes 345 facing the glass delivery channel. Air channel 344 is connected to an ion wind system (not shown). In this embodiment, the ion wind system can inject ion air into air channel 344, which is then blown toward the film surface through air holes 345. This can remove static electricity from the film and prevent dust from being attracted by static electricity after film coating.

[0048] Furthermore, air passage 344 can also be connected to a negative pressure system (not shown in the drawings). The negative pressure system creates a negative pressure at the position of air hole 345, thereby adsorbing the free end of the film onto guide plate 341 and securing the free end of the film. Specifically, after the free end of the film passes through, the air hole 345 on guide plate 341 secures the free end of the film, avoiding the problem of the free end of the film being loose and facilitating film transportation and coating. More preferably, the ion wind system and the negative pressure system can be freely switched according to actual needs.

[0049] Further, refer to Figures 2 to 4 The first conveying device 100 includes a frame 110, a transmission shaft 120, a third drive motor 130, multiple sets of conveyor belts 140, a moving mechanism 150, a limiting slide 160, a centering clamp 170, and a push rod 180. A mounting portion 111 is provided at one end of the frame 110 near the second conveying device 200, and the transmission shaft 120 is rotatably connected to the mounting portion 111. The third drive motor 130 is connected to the transmission shaft 120 and can drive the transmission shaft 120 to rotate. Multiple sets of conveyor belts 140 are installed on the frame 110, and each set of conveyor belts 140 is connected to the transmission shaft 120. When the third drive motor 130 drives the transmission shaft 120 to rotate, each conveyor belt 140 is driven to rotate together. The moving mechanism 150 is installed on the frame 110 and is located on the bottom side of the conveyor belts 140. The moving mechanism 150 includes a moving seat 151 that can move along the conveying direction of the glass. Specifically, the moving mechanism 150 further includes a driving mechanism 152 . The driving mechanism 152 may be an electric screw module or an electric belt mechanism. The driving mechanism 152 drives the moving seat 151 to move.

[0050] Reference Figure 3 Two sets of limiting slides 160 are arranged on the moving seat 151. Both limiting slides 160 are provided with a centering clamp 170, and the upper end of the centering clamp 170 is higher than the conveying belt 140. The two limiting slides 160 are connected to the adjustment drive mechanism 161. The adjustment drive mechanism 161 is used to drive the two limiting slides 160 to move relative to each other so that the positioning clamp 170 clamps the side of the glass on the conveying belt 140. The push rod 180 is arranged at the end of the moving seat 151 away from the second conveying device 200. Preferably, the adjustment drive mechanism 161 includes a double-headed screw and a motor. One end of the double-headed screw is provided with a left-handed thread and the other end is provided with a right-handed thread. The double-headed screw is respectively connected to the two limiting slides 160. The motor drives the double-headed screw to rotate, thereby making the two limiting slides 160 move synchronously. The glass to be coated can be placed on the conveyor belt 140. The movable base 151 of the movable mechanism 150 is translated, causing the push rod 180 on the movable base 151 to contact the end face of the glass. The adjustable drive mechanism 161 then pushes the two limit slides 160 to translate, causing the two centering clamps 170 to clamp on both sides of the glass to position the glass. After the glass is positioned, the conveyor belt 140 and the movable mechanism 150 jointly push the glass to be conveyed between the first driven roller 311 and the first driving roller 312. This ensures stable and efficient conveying of the glass, avoids problems such as slipping during conveyance and causing glass misalignment, and ensures that the glass is pushed at the set speed and distance, thereby ensuring the spacing between adjacent glass sheets and avoiding the problem of equal spacing between glass sheets during coating.

[0051] Further, refer to Figure 4 The conveyor belt 140 includes a moving beam 141, a driving pulley 142, a driven pulley 143, and a synchronous belt 144. The driving pulley 142 and the driven pulley 143 are respectively located at both ends of the moving beam 141, and the driving pulley 142 slides over the transmission shaft 120. Specifically, the transmission shaft 120 is a splined shaft, and the driving pulley 142 has a spline hole that fits over the spline shaft. Therefore, the spline shaft can drive the driving pulley 142 to rotate, and the driving pulley 142 can also slide on the spline shaft.

[0052] A timing belt 144 connects the driving pulley 142 and the driven pulley 143. The timing belt 144 is also supported by a moving beam 141. When the timing belt 144 supports the glass, the moving beam 141 also supports the glass. The moving beam 141 is equipped with a connecting seat 145, which is slidably connected to the frame 110. The connecting seat 145 is provided with a clearance groove 146 for the timing belt 144. Specifically, in this embodiment, the spacing between the conveyor belts 140 can be changed by sliding the moving beam 141, thereby adjusting the effective width of the conveying surface of the first conveying device 100. This allows for the conveyance of glass of varying widths while also allowing the centering clamp 170 to clamp and position the glass.

[0053] Further, refer to Figure 3 and Figure 4 The first conveying device 100 further includes an equidistant adjustment mechanism 190, which includes a rotating shaft 191 and a fourth drive motor 192. The rotating shaft 191 is rotatably connected to the frame 110 and is provided with a spiral groove 193. The movable beam 141 is provided with a toggle member 147 that extends into the spiral groove 192. More specifically, the rotating shaft 191 is provided with multiple spiral grooves 193, each having an unequal pitch, and adjacent spiral grooves 193 having a pitch that is twice the pitch of each other. Furthermore, the spiral grooves 193 at both ends of the rotating shaft 191 are symmetrically arranged. In this embodiment, the equidistant adjustment mechanism 190 can be used to adjust the equidistant distances of each conveyor belt 140.

[0054] Furthermore, a sensor is provided at the output end of the first conveying device 100. When the sensor senses the glass, the conveying belt 140 and the moving mechanism 150 work together to convey the glass, thereby accurately controlling the conveying speed and position of the glass, thereby accurately controlling the distance between the two glasses.

[0055] Further, refer to Figure 1 The glass upper and lower laminating machine further includes a support frame 500, which is located above the laminating device 300. One film unwinding mechanism 400 is mounted on the support frame 500, while another film unwinding mechanism 400 is mounted on the bottom side of the second conveyor device 200. Specifically, the second conveyor device 200 includes a fixed frame 201, within which the film unwinding mechanism 400 is mounted.

[0056] Further, refer to Figure 9 The film roll unwinding mechanism 400 includes two groups of film roll racks 410 and a film splicing mechanism 420. The film roll racks 410 are used to place the film roll. And the film rolls on the two groups of film roll racks 410 can be connected without stopping the machine. Specifically, the film splicing mechanism 420 includes a base 421, a lower hot pressing mold 422, a mounting frame 423, a pressing mechanism 424, an upper hot pressing mold 425, a lower film cutting knife 426 and an upper film cutting knife 427. The lower hot pressing mold 422 and the lower film cutting knife 426 are arranged on the base 421. Among them, the lower film cutting knife 426 includes a telescopic cylinder 4260 and a lower hot cutting knife 4261, and the lower hot cutting knife 4261 is provided with a heating tube.

[0057] A mounting frame 423 is mounted above the base 421. Specifically, the mounting frame 423 is mounted on the fixed frame 201 of the second conveyor 200. A pressing mechanism 424 and an upper film cutting knife 427 are mounted on the mounting frame 423. The upper film cutting knife 427 comprises a cylinder 4270 and an upper hot cutting knife 4271, which is connected to the cylinder 4270. An upper hot pressing die 425 is mounted at the bottom end of the pressing mechanism 424.

[0058] In this embodiment, when the film rolls are connected, if the next film roll needs to be connected to the top side of the previous film roll, the free end of the film roll to be replaced is pulled between the lower hot pressing die 422 and the upper hot pressing die 425. The lower pressure mechanism 424 pushes the upper hot pressing die 425 downward, hot-pressing the two films together. Furthermore, the telescopic cylinder 4260 pushes the lower hot cutter 4261 upward to contact the bottom film, cutting the bottom film, thereby achieving the connection and switching of the film rolls. Conversely, when switching the upper film, the lower film is pulled between the lower hot pressing die 422 and the upper hot pressing die 425. The lower pressure mechanism 424 pushes the upper hot pressing die 425 downward, hot-pressing the two films together.
