Description

Technical Field

[0001] The present application relates to the technical field of glass production equipment, and particularly relates to a dust-free laminating device for preparing laminated glass. Background Art

[0002] Laminated glass is a composite glass product in which two or more pieces of glass are sandwiched with one or more layers of organic polymer interlayers, and after being processed by special high-temperature pre-pressing (or vacuum pumping) and high-temperature and high-pressure processes, the glass and the interlayer are permanently bonded into one body.

[0003] When preparing laminated glass, one step is to lay the film flat on the glass and then cover it with another piece of glass, which usually requires manual participation, restricting the automation level of laminated glass production and needing to be optimized and improved.

[0004] Secondly, when laying the film, there are often phenomena of film wrinkles, resulting in bubbles in the laminated glass that are difficult to eliminate even by rolling, affecting the product quality. Summary of the Invention

[0005] The present application provides a dust-free laminating device for preparing laminated glass. Through the reciprocating movement of the clamping roller, the clamping roller can always move along with the free end of the film and clamp the free end. Then, through the swinging reciprocating movement of the laying roller, the laying of the film is realized, improving the automation level in the laminating process and the quality of film laying.

[0006] To achieve the above object, the present application adopts the following technical solution: A dust-free laminating device for preparing laminated glass, including a conveying table, a moving vehicle, and a film laying member.

On both sides of the bottom of the lifting frame, positioning rollers are provided. Between the two positioning rollers, a clamping roller is provided. The clamping roller can move towards any one of the positioning rollers and press closely against the positioning roller. The lifting frame is connected with a laying roller capable of rotating around the film roll, and when the laying roller reaches between the two positioning rollers, it changes to horizontal movement. The laying roller can press closely against the highest point of the positioning roller and clamp the film. The film laying member further includes a cutting member, which can cut off the film between the laying roller and the glass. The cutting position is at a distance L from the laying roller, and L is greater than one-fourth of the cross-sectional perimeter of the positioning roller.

[0007] Further, the clamping roller is connected with a sliding block connected to the lifting frame. The lifting frame is fixedly connected with a guide rod. The guide rod passes through the sliding block and is movably connected with the sliding block. The lifting frame is connected with a swinging motor, and the swinging motor is connected with the sliding block through a swing frame with a telescopic end.

[0008] Further, a rotating motor and a guide plate are provided on the lifting frame. The rotating motor is connected to a rotating frame with a telescopic end. In the natural state, the rotating frame remains in a contracted state. A constraint roller is provided at the telescopic part of the rotating frame. The end of the rotating frame is connected to the laying roller. The lower half of the guide plate has a horizontal guiding surface, and both bottom endpoints on both sides exceed the positioning rollers on both sides. The upper half of the guide plate inclines towards the film, and the minimum distance between the upper half of the swing frame and the film is less than the distance between the constraint roller and the film in the retracted state.

[0009] Further, a tension roller is provided on one side of the film. The film roll contacts the positioning roller after passing around the tension roller. The tension roller has a rotational resistance.

[0010] Further, the cutting member is hinged to the laying roller. The laying roller can eject blades from two directions to cut the film.

An electromagnet is provided in the middle of the cylinder. A magnet and a tension spring are provided between the blade and the electromagnet. The opposite surfaces of the two magnets have the same magnetic poles.

[0012] Further, the distance between the lowest point of the laying roller and the lowest point of the cutting member is greater than the distance between the lowest point of the laying roller and the upper edge of the glass. When the cutting member is horizontal with the lowest point of the laying roller, the ejection direction of the blade inclines towards the positioning roller, and the contact point between the blade and the film is between the glass and the positioning roller.

Detailed Embodiments

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts belong to the scope of protection of the present application. Embodiment 1

[0029] Please refer to Figures 1 - 3 , a dust-free laminating device for preparing laminated glass, including a conveying table 1, a moving vehicle 2 and a glue spreading member 3. The washed and dried glass is positioned on the conveying table 1. The moving vehicle 2 is connected to the overhead rail and moves along the overhead rail. Figures 1 - 4 The overhead rail and the glass hoisting device are omitted. The glue spreading member 3 includes a lifting frame 31 connected to the moving vehicle 2 and capable of lifting. The lifting frame 31 is slidably connected to the moving vehicle 2 through a guiding member 311. The guiding member 311 is composed of a slider and a slide rail. A cylinder 312 is provided between the lifting frame 31 and the moving vehicle 2. Driven by the cylinder 312, the lifting frame 31 makes a lifting motion. The lifting frame 31 is connected with a roll of glue 32. An installation frame 313 with an upper opening is provided on the lifting frame 31. The roll of glue 32 can be directly placed on the installation frame 313. Positioning rollers 33 are provided on both sides of the bottom of the lifting frame 31. The positioning rollers 33 are perpendicular to the conveying direction of the conveying table 1. A horizontal installation groove 333 is provided at the bottom of the positioning roller 33. "Horizontal" refers to the direction in which the moving vehicle 2 slides. An adjusting block 331 is movably connected in the installation groove 333. The adjusting block 331 is movably connected with an adjusting lead screw 332. The adjusting lead screw 332 is threadedly connected with the adjusting block 331. Rotating the adjusting lead screw 332 drives the adjusting block 331 to move. The positioning roller 33 is connected with the adjusting block 331 to adjust the positions of the two positioning rollers 33 to adapt to the width of the glass. A clamping roller 34 is provided between the two positioning rollers 33. The clamping roller 34 can move towards any one of the positioning rollers 33 and press against the positioning roller 33. The pressure between the positioning roller 33 and the clamping roller 34 can clamp the film. The highest points of the positioning roller 33 and the clamping roller 34 are on the same horizontal plane. The lifting frame 31 is connected with a laying roller 35 capable of rotating around the roll of glue 32. And when the laying roller 35 reaches between the two positioning rollers 33, it changes to make a horizontal movement. The laying roller 35 can press against the highest point of the positioning roller 33 and clamp the film. The glue spreading member 3 further includes a cutting member 37. The cutting member 37 can cut off the film between the laying roller 35 and the glass. The cutting position is at a distance L from the length of the laying roller 35. L is greater than one-fourth of the cross-sectional circumference of the positioning roller 33, that is, the free end of the newly formed film roll is lower than the axis of the positioning roller 33, which is convenient for the clamping roller 34 to clamp the free end of the film. The height of the conveying wheel 11 protruding from the edge of the conveying table 1 on the conveying table 1 is greater than the sum of the diameter of the positioning roller 33 and L, so as to facilitate the laying of the film.

[0030] Please refer to Figures 4 - 6When preparing for production, the free end of the wound film on the film roll 32 is placed between the positioning roller 33 and the clamping roller 34. The clamping roller 34 and the positioning roller 33 clamp the free end of the film. The laying roller 35 is on the outside of the film. The height of the laying member 3 is lowered as a whole so that the highest point of the positioning roller 33 is flush with the glass. The laying roller 35 moves horizontally, pulling the film to move, and laying the film on the glass. When the laying roller 35 contacts the positioning roller 33 at the other end, the laying roller 35 stops moving. The positioning roller 33 is provided with a sensor 38 corresponding to the contact position with the clamping roller 34 and the laying roller 35. The sensor 38 can be a pressure proximity switch. The specific type can be flexibly set by those skilled in the art according to needs. The sensor 38 is located on one side of the positioning roller 33 and will not interfere The film moves, and the sensor 38 stops moving after detecting contact with the laying roller 35. At the same time, the cutting piece 37 is triggered to cut the film, the clamping roller 34 is disengaged from the positioning roller 33, and the other end of the film is released. Then the laying member 3 rises as a whole and makes way, and the lifting device places another piece of positioned glass on and presses it on the previous piece of glass and the film. At the same time, the clamping roller 34 moves toward the positioning roller 33 on the other side. When the contact of the clamping roller 34 is detected, that is, the clamping roller 34 clamps the free end of the film again, the laying roller 35 moves in the opposite direction, rotates around the film roll 32 to the outside of the film to complete the reset, and prepares for laying the glue of the next piece of glass. This process contacts the positioning roller 33 twice, that is, after the laying roller 35 is detected to be in contact with the positioning roller 33 for the second time, it stops moving and stands by.

[0031] See also Figure 7 The clamping roller 34 is connected to a sliding block 341 connected to the lifting frame 31, and the lifting frame 31 is fixedly connected to a guide rod 342. The guide rod 342 passes through the sliding block 341 and is movably connected to the sliding block 341. The lifting frame 31 is connected to a swing motor 344. The swing motor 344 is connected to the sliding block 341 through a swing frame 343 with a retractable end. The swing motor 344 drives the swing frame 343 to swing. When the swing frame 343 swings, the sliding block 341 moves along the guide rod 342, so that the clamping roller 34 moves in a straight line, and the swing frame 343 is also retracted. The sliding block 341 and the guide rod 342 are located on one side of the film 32 and will not interfere with the film.

[0032] See also Figure 3 and Figure 7, a lifting frame 31 is provided with a rotating motor 351 and a guide plate 353. The rotating motor 351 is connected with a rotating frame 352 whose end part can be telescopic, and in the natural state, the rotating frame 352 remains in the contracted state. A restraint roller 354 is provided at the telescopic part of the rotating frame 352. The end part of the rotating frame 352 is connected with the laying roller 35. The lower half part of the guide plate 353 has a horizontal guiding surface, and both side endpoints at the bottom cross over the positioning rollers 33 on both sides. The upper half part of the guide plate 353 inclines towards the film 32, and the minimum distance between the upper half part of the swing frame 343 and the film 32 is less than the distance between the restraint roller 354 and the film 32 in the retracted state, ensuring that the restraint roller 354 can move along the guide plate 353. When the restraint roller 354 moves along the guide plate 353, the rotating frame 352 is telescoped, realizing the rotation and linear motion of the laying roller 35. The guide plate 353 is located on one side of the film 32 and will not interfere with the film.

[0033] Please refer to Figure 7 , a tension roller 36 is provided on one side of the film 32. The film roll bypasses the tension roller 36 and then contacts the positioning roller 33. The tension roller 36 has appropriate rotational resistance, enabling the film roll to maintain a flat state when being pulled by the laying roller 35.

[0034] Please refer to Figure 8 , a cutting member 37 is hinged to the laying roller 35 and is installed on the rotating shaft of the laying roller 35. When the laying roller 35 moves horizontally across the positioning roller 33, the cutting member 37 is dragged horizontally by it. The laying roller 35 can eject blades from two directions to cut the film. When the cutting member 37 is horizontal with the lowest point of the laying roller 35, blades can be ejected from both the upper and lower sides of the cutting member 37. Since the laying roller 35 alternately clamps the film from both sides, the cutting member 37 also alternately ejects blades from two directions.

[0035] Please refer to Figure 9 , the cutting member 37 includes a cylinder body 371. The cylinder body 371 is cylindrical. Blades 372 are provided on both the upper and lower sides of the cylinder body 371. An electromagnet 374 is provided in the middle of the cylinder body 371. A magnet 373 and a tension spring 375 are provided between the blade 372 and the electromagnet 374. The tension spring 375 keeps the blade 372 in the contracted state. The opposite surfaces of the two magnets 373 have the same magnetic poles. When the electromagnet 374 is powered on, it generates an attractive force on one magnet 373 and a repulsive force on the other magnet 373, causing the blade 372 to move towards one side. Appropriately setting the quantity and intervals of the magnet 373, the electromagnet 374, and the tension spring 375 enables the longer blades 372 to move in unison.

[0036] The distance between the lowest point of the laying roller 35 and the lowest point of the cutting member 37 is greater than the distance from the lowest point of the laying roller 35 to the upper edge of the glass. When the cutting member 37 and the lowest point of the laying roller 35 are horizontal, the blade ejection direction is inclined towards the positioning roller 33, and the contact point between the blade and the film is between the glass and the positioning roller 33. When cutting the film, the cutting member 37 presses the film to reduce the risk of the tension during cutting interfering with the film.

[0037] Please refer to Figure 10 , an elastic filler is provided between the connecting shaft of the positioning roller 33 and the outer housing. The housings of the positioning roller 33, the clamping roller 34, and the laying roller 35 are all made of magnetic materials or have a part with magnetism, and the housings of the clamping roller 34 and the laying roller 35 both show suction force with the housing of the positioning roller 33. When the clamping roller 34 and the laying roller 35 approach the positioning roller 33, they are naturally attracted and tightened under the magnetic force to maintain the reliability of holding the film.

[0038] Please refer to Figure 2 , a pulling member 334 is provided on the outer side of the positioning roller 33. When the pulling member 334 is wound up, it pulls the positioning roller 33 outwards, compresses the elastic filler, moves the housing of the positioning roller 33, and separates it from the clamping roller 34 to release the film. Subsequently, the entire film laying member 3 descends by L again, enabling the film to droop freely past the clamping roller 34 and avoiding the risk of flipping the film when the clamping roller 34 is lifted.
