Description

Technical Field

[0001] This invention relates to the field of dust removal technology for adhesive backing applications, specifically a dust removal structure for adhesive backing application equipment. Background Technology

[0002] The main function of the dust removal structure used in adhesive bonding equipment is to effectively clean the surface of the substrate (such as paper, thin plastic sheet, thin steel plate, etc.) before hot pressing the film and the substrate. This removes various contaminants from the substrate surface, preventing poor adhesion, bubbles, bumps, or appearance defects between the film and the substrate caused by contaminants, and ensuring a high yield and high-quality appearance of the adhesive products.

[0003] Patent CN208827292U discloses a single-sided coating device for color steel plate processing, including a base and two supports. The two supports are fixedly connected to the top of the base, and fixed plates are slidably connected to both sides of the two supports. A first mounting plate is welded to the side of the two fixed plates that are close to each other. The first mounting plate has a U-shaped structure. A first film roller and a first coating roller are rotatably connected between the two first mounting plates. A second mounting plate is welded to the bottom of the top of the two first mounting plates, and a second film roller is rotatably connected between the two second mounting plates. The second film roller is located between the first film roller and the first coating roller. This patent has a reasonable structure, ingenious design, and simple operation. It not only facilitates the adjustment of the distance between the first coating roller and the second coating roller, but also effectively prevents the fixed plates from loosening, thereby solving the defect of the prior art color steel plate coating device that is not convenient to adjust the pressure between the coating rollers.

[0004] However, the above-mentioned device has the following problems: during the process of treating the contamination of the substrate surface, the dust removal structure of the adhesive application equipment causes the contaminants to adhere to the substrate surface, which leads to poor adhesion between the adhesive and the substrate surface. At the same time, the adhesive surface of the adhesive solidifies, which can easily cause the adhesive to not adhere to the substrate surface. Furthermore, small dust particles adhere to the substrate surface, which can lead to the substrate not being properly adhesiveped. Therefore, we propose a dust removal structure for adhesive application equipment. Summary of the Invention

[0034] This invention provides a dust removal structure for adhesive application equipment. It has the following beneficial effects:

[0035] (1) The present invention uses a housing, a top shell, a cover, a conveyor table, an adhesive coating assembly, a square frame, a servo cylinder, an H-shaped plate, an electrostatic roller, and a frame with a chamfering plate. The telescopic end of the servo cylinder drives the H-shaped plate to move downward, the H-shaped plate drives the electrostatic roller to move downward, the H-shaped plate drives the frame to move downward, and the frame drives the chamfering plate to move downward. During the downward movement, the chamfering plate comes into contact with the substrate surface and removes the contaminants attached to the substrate surface. The electrostatic roller rolls on the substrate surface and the electrostatic charge on the electrostatic roller adsorbs dust particles on the substrate surface, preventing contaminants from sticking to the substrate surface and causing poor adhesion between the adhesive and the substrate surface.

[0036] (2) By setting up a preheating device, the U-shaped rod, the long plate and the shell cooperate with the resistance heating rod. The U-shaped rod drives the long plate to move downward, the long plate drives the shell to move downward, the shell drives the resistance heating rod to move downward, and the resistance heating rod transfers heat to the surface of the substrate to prevent the adhesive surface of the backing from solidifying and causing the backing to not stick to the surface of the substrate.

[0037] (3) The present invention uses a preheating device to make the ring frame and roller cooperate with the concave strip frame. The ring frame drives the roller to move downward, and the roller rolls downward in the concave strip frame. The concave strip frame limits the roller to prevent the electrostatic roller from excessively squeezing the substrate surface and causing deformation and damage to the substrate surface.

[0038] (4) The present invention, through the setting of the monitoring device, enables the L-shaped rod, the second long plate and the laser emitter to work together with the photosensitive component. The L-shaped rod drives the second long plate to move downward, the second long plate drives the laser emitter to move downward, and the second long plate drives the photosensitive component to move downward. When there are dust particles on the surface of the substrate, the laser received by the photosensitive component is blocked. Conversely, it indicates that the surface of the substrate is clean. The defective products are detected in time, and small dust particles are prevented from adhering to the surface of the substrate and causing the substrate to be unqualified for adhesive backing.

[0039] (5) The present invention, through the setting of the monitoring device, makes the round tube and the inclined plate cooperate with the cylinder, the long plate supports the cylinder, and the round tube supports the L-shaped rod to move downward, so as to prevent the L-shaped rod from moving downward and causing violent shaking, resulting in poor monitoring effect of laser emitter and photosensitive component.

[0052] The cover 3 is hinged to the top surface of the top shell 2. An observation window is provided on the back of the cover 3. The outer wall of the cover 3 is in sliding contact with the inner wall of the shell 1.

[0053] Conveyor 4 is located at the bottom of the machine housing 1. Two rollers are installed on the upper part of the inner wall of conveyor 4. A conveyor belt is installed on the outer wall of the rollers of conveyor 4. Two servo motors are installed on the left side of conveyor 4. The rotating shafts of the two servo motors of conveyor 4 are fixedly connected to the left side of the two rollers.

[0054] The adhesive coating assembly 5 is located on the left and right sides of the conveyor table 4. The adhesive coating assembly 5 includes: a bending frame 501, a rubber roller 502, a Y-shaped frame 503, two circular rollers 504, a servo cylinder 505, a U-shaped long frame 506, and a circular roller 507. The bending frame 501 is fixed on the left and right sides of the conveyor table 4. The top surface of the bending frame 501 is provided with a groove. The rubber roller 502 is placed in the groove of the bending frame 501. The Y-shaped frame 503 is fixed on the outer wall of the bending frame 501. The two circular rollers 504 are rotatably installed on the left and right sides of the Y-shaped frame 503. The servo cylinder 505 is fixed in the middle of the top surface of the Y-shaped frame 503. The telescopic end of the servo cylinder 505 passes through and slides in the middle of the top surface of the Y-shaped frame 503. The U-shaped long frame 506 is fixed on the bottom surface of the telescopic end of the servo cylinder 505. The circular roller 507 is rotatably installed on the left and right sides of the inner wall of the U-shaped long frame 506.

[0055] Square frame 6 is fixed on the left and right sides of conveyor table 4 and is located in front of adhesive coating assembly 5;

[0056] Servo electric cylinder 7 is fixedly installed in the middle of the top surface of the square frame 6. The telescopic end of servo electric cylinder 7 passes through and slides in the middle of the top surface of the square frame 6.

[0057] H-shaped plate 8 is fixed to the bottom surface of the telescopic end of the servo electric cylinder 7. H-shaped plate 8 is located inside the square frame 6.

[0058] Two electrostatic rollers 9 are mounted on the left and right sides of the inner wall of the H-shaped plate 8 at both ends, and the electrostatic rollers 9 are located above the conveyor belt of the conveyor table 4.

[0059] Two frames 10 are embedded in the left and right sides of the H-shaped plate 8;

[0060] Chamfer plate 11 is fixed to the top surface of the two frames 10. The bottom of the chamfer plate 11 is chamfered. The chamfer plate 11 is used to remove contaminants attached to the surface of the substrate.

[0061] When using this structure, the housing 1 supports the top housing 2. The operator opens the cover 3 from the rear of the top housing 2. The operator places the rubber roller 502 in the groove of the bending frame 501. The Y-shaped frame 503 supports the first round roller 504. The operator wraps the adhesive backing on the rubber roller 502 around the surface of the first round roller 504, and then sticks the adhesive backing on the rubber roller 502 to the underside of the surface of the second round roller 507. The operator starts the conveyor table 4 through the control console. The servo motor shaft starts to rotate forward, which drives the roller shaft to rotate forward, and the roller shaft drives the conveyor belt to rotate forward. The operator places the substrate on the conveyor belt surface, and the conveyor belt transports the substrate backward. The operator activates servo cylinder 2 505 on the Y-shaped frame 503 via the control console. The telescopic end of servo cylinder 2 505 begins to move downward within the Y-shaped frame 503. This telescopic end of servo cylinder 2 505 drives the U-shaped long frame 506, which in turn drives the circular roller 2 507 downward. The circular roller 2 507 then drives the adhesive backing of the rubber roller 502 downward. When the adhesive roller 502 comes into contact with the substrate surface, it adheres to the substrate surface. Under the action of friction, the substrate drives the adhesive roller 502 to move backward, and the adhesive of the coating component 5 covers the substrate surface. When the substrate is placed on the conveyor belt surface, the conveyor table 4 supports the square frame 6. The operator starts the servo cylinder 7 on the square frame 6 through the control console. The extension end of the servo cylinder 7 begins to move downward. The extension end of the servo cylinder 7 moves downward in the square frame 6. The extension end of the servo cylinder 7 drives the H-shaped plate 8 to move downward. The H-shaped plate 8 drives the electrostatic roller 9 to move downward. At the same time, the H-shaped plate 8 drives the frame 10 to move downward. The frame 10 drives the chamfer plate 11 to move downward. The chamfer plate 11 comes into contact with the substrate surface during the downward movement. The chamfer plate 11 removes the contaminants attached to the substrate surface. The electrostatic roller 9 rolls on the substrate surface. The electrostatic adsorption on the electrostatic roller 9 adsorbs the dust particles on the substrate surface, thereby avoiding the problem of the contaminants sticking to the substrate surface and causing poor adhesion between the adhesive and the substrate surface when the dust removal structure of the adhesive application equipment is used to deal with the contamination of the substrate surface.

[0062] A preheating device 12 is provided on the top surface of the two frames 10. The preheating device 12 is used to heat the surface of the substrate. A monitoring device 13 is provided on the back of the preheating device 12. The monitoring device 13 is used to monitor the surface of the substrate.

[0063] Working principle: Open the machine cover 3 from the rear of the top shell 2, place the rubber roller 502 in the groove of the bending frame 501, wrap the adhesive on the rubber roller 502 around the surface of the first round roller 504, and then stick the adhesive on the rubber roller 502 to the underside of the surface of the second round roller 507. Place the substrate on the surface of the conveyor belt, and the conveyor belt transports the substrate backward. The telescopic end of the second servo cylinder 505 drives the U-shaped long frame 506, which in turn drives the second round roller 507 to move downward. The second round roller 507 then moves the adhesive on the rubber roller 502 downward, bringing the adhesive on the rubber roller 502 into contact with the surface of the substrate. On the substrate surface, under the action of friction, the substrate drives the adhesive backing of the rubber roller 502 to move backward, covering the substrate surface. When the substrate is placed on the conveyor belt surface, the telescopic end of the servo cylinder 7 drives the H-shaped plate 8 to move downward. The H-shaped plate 8 drives the electrostatic roller 9 to move downward. The H-shaped plate 8 drives the frame 10 to move downward. The frame 10 drives the chamfer plate 11 to move downward. During the downward movement, the chamfer plate 11 contacts the substrate surface and removes the contaminants attached to the substrate surface. The electrostatic roller 9 rolls on the substrate surface, and the electrostatic adsorption on the electrostatic roller 9 adsorbs dust particles on the substrate surface.

[0064] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the preheating device 12 includes: a U-shaped rod 121, which is fixed to the top surface of the two frames 10 respectively;

[0065] Long plate 122 is fixed to the bottom surface of two U-shaped rods 121;

[0066] Housing 123, housing 123 is fixed to the bottom surface of long plate 122;

[0067] Several resistance heating rods 124 are fixed on the left and right sides of the inner wall of the housing 123.

[0068] Several resistance heating rods 124 are used to heat the surface of the substrate;

[0069] As the H-shaped plate 8 moves the frame 10 downwards, the frame 10 moves the U-shaped rod 121 downwards, the U-shaped rod 121 moves the long plate 122 downwards, the long plate 122 moves the housing 123 downwards, and the housing 123 moves the resistance heating rod 124 downwards. The operator starts the resistance heating rod 124 through the control panel to heat up. The resistance heating rod 124 transfers heat to the surface of the substrate, thus avoiding the problem of adhesive not adhering to the substrate surface when the dust removal structure of the adhesive application equipment condenses on the surface of the substrate during the treatment of substrate contamination.

[0070] A ring frame 125 is fixed to the outer wall of the U-shaped rod 121. A roller 126 is rotatably installed on the inner wall of the two ring frames 125. A concave strip frame 127 is fixed on the left and right sides of the inner wall of the square frame 6. The outer walls of the two rollers 126 and the inner walls of the two concave strip frames 127 roll in contact.

[0071] As the U-shaped rod 121 moves the long plate 122 downward, the U-shaped rod 121 also moves the ring frame 125 downward. The ring frame 125 then moves the roller 126 downward. The roller 126 rolls downward in the concave frame 127. The concave frame 127 limits the roller 126, preventing the electrostatic roller 9 from excessively squeezing the substrate surface. This avoids the problem of the electrostatic roller 9 excessively squeezing the substrate surface and causing deformation and damage to the substrate surface when the dust removal structure of the adhesive application equipment is processing substrate surface contamination.

[0072] The monitoring device 13 includes: an L-shaped rod 131, which passes through and is fixed to the back of the two ring frames 125 respectively;

[0073] Long plate 2 132 is fixed to the bottom surface of two L-shaped rods 131;

[0074] Laser emitter 133 is fixed to the right side of the bottom surface of long plate 132;

[0075] Photosensitive component 134 is fixed to the left side of the bottom surface of long plate 132;

[0076] Laser emitter 133 and photosensitive component 134 monitor whether there are contaminants on the surface of the substrate;

[0077] As the ring frame 125 drives the roller 126 downward, the ring frame 125 drives the L-shaped rod 131 downward, the L-shaped rod 131 drives the second long plate 132 downward, the second long plate 132 drives the laser emitter 133 downward, and the second long plate 132 drives the photosensitive component 134 downward. The operator starts the laser emitter 133 through the control panel. The laser emitter 133 emits a laser, and the photosensitive component 134 receives the laser emitted by the laser emitter 133. When there are dust particles on the surface of the substrate, the laser received by the photosensitive component 134 is blocked. Conversely, it indicates that the surface of the substrate is clean, and unqualified defective products are detected in time. This avoids the problem of small dust particles adhering to the surface of the substrate and causing unqualified adhesive application when the dust removal structure of the adhesive application equipment is dealing with surface contamination of the substrate.

[0078] A round tube 135 is fixed to the outer wall of each of the two L-shaped rods 131. An inclined plate 136 is fixed to the outer wall of each of the two round tubes 135. A cylinder 137 is fixed to the side of each of the two inclined plates 136 away from the round tubes 135. The bottom surface of the two cylinders 137 is connected to the top surface of the long plate 122.

[0079] While the L-shaped rod 131 drives the second long plate 132 to move downward, the L-shaped rod 131 drives the round tube 135 to move downward, the round tube 135 drives the inclined plate 136 to move downward, the inclined plate 136 drives the cylinder 137 to move downward, the first long plate 122 supports the cylinder 137, and the round tube 135 supports the L-shaped rod 131 to move downward. This avoids the problem that the dust removal structure of the adhesive application equipment will cause the L-shaped rod 131 to vibrate violently when it moves downward, resulting in poor monitoring effect of the laser emitter 133 and the photosensitive component 134 when the substrate surface is contaminated.

[0080] Working principle: The frame 10 drives the U-shaped rod 121 to move downward, the U-shaped rod 121 drives the long plate 122 to move downward, the long plate 122 drives the shell 123 to move downward, the shell 123 drives the resistance heating rod 124 to move downward, and the resistance heating rod 124 transfers heat to the surface of the substrate.

[0081] U-shaped rod 121 drives ring frame 125 to move downward, ring frame 125 drives roller 126 to move downward, roller 126 rolls downward in concave frame 127, concave frame 127 limits roller 126.

[0082] The ring frame 125 drives the L-shaped rod 131 to move downward, the L-shaped rod 131 drives the second long plate 132 to move downward, the second long plate 132 drives the laser emitter 133 to move downward, the second long plate 132 drives the photosensitive component 134 to move downward, the laser emitter 133 emits laser, and the photosensitive component 134 receives the laser emitted by the laser emitter 133. When there are dust particles on the surface of the substrate, the laser received by the photosensitive component 134 is blocked, otherwise it indicates that the surface of the substrate is clean, and unqualified defective products are detected in time.

[0083] L-shaped rod 131 drives round tube 135 to move downward, round tube 135 drives inclined plate 136 to move downward, inclined plate 136 drives cylinder 137 to move downward, long plate 122 supports cylinder 137, allowing round tube 135 to support L-shaped rod 131 to move downward.
