Description

Technical Field

[0001] This invention relates to the field of substrate coating, specifically an adsorption-type automatic substrate coating device. Background Technology

[0002] A glue coating machine, also known as a coating machine, glue scraper, or automatic glue sprayer, is a mechanical device mainly used to apply liquid glue to the surface of substrates, cardboard boxes, or leather. There are many types of glue coating machines available. Surface glue coating is a common processing method in the processing of ultra-thin aluminum sheets. Glue coating on the surface of ultra-thin aluminum sheets allows for lamination or the bonding of multiple layers of ultra-thin aluminum sheets, increasing the thickness and strength of the ultra-thin aluminum sheets.

[0003] Existing automatic gluing devices for ultra-thin aluminum plates are generally designed for gluing surfaces of 18mm thick ultra-thin aluminum plates. However, for ultra-thin aluminum plates with a thickness of less than 2mm, the edges of the plates may deform due to glue sticking and getting caught in the glue roller, which does not meet user needs. Therefore, we propose an adsorption-type automatic gluing device for substrates. Summary of the Invention

[0004] The purpose of this invention is to provide an adsorption-type automatic adhesive coating device for substrates, in order to solve the problem mentioned in the background art that thin plates will be rolled into the coating wheel due to the stickiness of the adhesive, causing the substrate to bend under stress.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adsorption-type automatic adhesive coating device for substrates, comprising a base, with supporting slide rails slidably connected to both ends of the base, a pneumatic push cylinder fixedly connected to the top of the base, a pneumatic lifting platform fixedly connected to the output end of the pneumatic push cylinder, a vacuum suction cup fixedly connected to the top of the pneumatic lifting platform, a non-powered roller screwed onto one side of the vacuum suction cup at the top of the pneumatic lifting platform, an electric push cylinder fixedly connected to the top edge of the pneumatic lifting platform, a positioning stop fixedly connected to the output end of the electric push cylinder, connecting frames fixedly connected to both sides of the top of the base, a folding rod screwed onto the top of the connecting frame, a limiting groove plate movably connected to one end of the folding rod, a roller screwed onto the connection between the limiting groove plate and the folding rod, and a supporting roller provided on one side of the limiting groove plate.

[0006] Based on the above structure, the sliding base drives the thin plate head at the top of the vacuum suction cup to move. The vacuum suction cup uses negative pressure to counteract the stickiness of the adhesive, ensuring that the plate head will not be deformed due to adhesive sticking and getting rolled into the glue roller during the aluminum plate coating process. It should be noted that, as shown in the figure, because the distance between the subsequent active roller group and the non-powered roller increases when the adsorption mechanism moves forward, a gap is created in the support, and therefore three sets of folding rods are set to provide subsequent support.

[0007] Preferably, the base is provided with an adhesive application frame on its exterior. A drive motor is fixedly connected to the inner wall of the adhesive application frame. A ball screw is fixedly connected to the output end of the drive motor. A ball slider fixedly connected to the bottom end of the base is threaded onto the outer wall of the ball screw.

A feeding frame is fixedly connected to the outer wall of the adhesive application frame.

[0008] Preferably, the folding rods are provided in three sets, and the three sets of folding rods are parallel.

[0010] Preferably, a stirring motor is fixedly connected to one end of the feeding hopper, and a rotating shaft that is screwed onto the inner wall of the feeding hopper is fixedly connected to the output end of the stirring motor. A stirring plate is fixedly connected to the outer wall of the rotating shaft. A feeding trough plate is fixedly connected to the bottom end of the feeding hopper. A servo motor is fixedly connected to the side wall of the feeding hopper. A threaded rod is fixedly connected to the output end of the servo motor. A lifting slider that is slidably connected to the outer wall of the feeding hopper is threaded onto the outer wall of the threaded rod. Adjusting rods are screwed onto both ends of the lifting slider. A connecting slider that is slidably connected to the outer wall of the feeding trough plate is screwed onto the bottom end of the adjusting rod. A pointer is fixedly connected to the bottom end of the connecting slider. A scale is fixedly connected to one side of the pointer on the outer wall of the feeding trough plate. An adjusting trough plate that is slidably connected to the inner wall of the feeding trough plate is fixedly connected to the outer wall of the connecting slider. A limit guide groove is provided at the connection between the adjusting trough plate and the feeding trough plate. A connecting groove is provided on the outer wall of the adjusting trough plate. A discharge groove is provided on the outer wall of the feeding trough plate.

[0011] Preferably, the stirring plates are provided in two sets, the two sets of stirring plates are symmetrical about the feeding hopper, and the stirring plates are spiral in shape.

[0012] Preferably, the lengths of the connecting groove and the discharge groove are equal, and four sets of discharge grooves are provided, which are equidistantly distributed along the bottom end of the feeding trough plate.

[0013] Preferably, an adjusting cylinder is screwed to the bottom end of the feeding frame, a telescopic plate is screwed to the output end of the adjusting cylinder, a first fixed roller is screwed to the outer wall of the telescopic plate, telescopic groove plates are fixedly connected to both ends of the telescopic plate, a first connecting rod is screwed to one end of the first fixed roller, a first connecting plate is screwed to the outer wall of the first connecting rod, a second connecting rod is screwed to the bottom end of the first connecting rod, a second connecting plate is screwed to the outer wall of the second connecting rod, an intermediate roller is screwed to the top end of the second connecting rod and slidably connected to the inner wall of the telescopic groove plate, a second fixed roller is screwed to the top end of the feeding frame, and a limiting hole groove is sleeved on the outer wall of the telescopic groove plate and fixedly connected to the top end of the feeding frame.

[0014] Preferably, the telescopic groove plate forms a telescopic structure through the telescopic plate and the limiting hole groove, the first connecting plate, the second connecting plate and the telescopic groove plate are parallel, and the first connecting rod and the second connecting rod are distributed in a "V" shape.

[0015] Preferably, the intermediate rollers are provided in three sets, and the three sets of intermediate rollers form an equidistant telescopic structure with the telescopic groove plate through the first connecting rod and the second connecting rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting a first fixed roller, an intermediate roller, and a second fixed roller, the operation of the adjusting cylinder drives the telescopic groove plate on the outer wall of the telescopic plate to slide along the inner wall of the limiting hole groove, so that the telescopic plate drives the first fixed roller to move relative to the second fixed roller at the top of the feeding frame. At the same time, the movement of the first fixed roller drives the intermediate roller to slide along the inner wall of the telescopic groove plate through the first connecting rod and the second connecting rod. By setting the first connecting plate and the second connecting plate, the three sets of intermediate rollers slide at equal distances along the inner wall of the telescopic groove plate, realizing the adjustment of the telescopic length of the telescopic groove plate. It should be noted that by extending and retracting the telescopic groove plate, thin plates of different lengths can be fed efficiently, avoiding the problem that thin plates that are too long will bend under stress, and thin plates that are too short will result in a large area occupied by the feeding frame.

[0018] 2. By setting up stirring plates, the stirring motor drives two sets of symmetrical stirring plates to rotate through the rotating shaft. The spiral stirring plates rotate to achieve the stirring operation of the adhesive material and prevent the adhesive material from sticking together.

[0019] 3. By setting up a connecting groove and a discharge groove, the lifting slider slides and drives the adjusting groove plate at one end of the connecting slider to slide along the inner wall of the limiting guide groove through the adjusting support rod. The sliding of the adjusting groove plate drives the connecting groove and the discharge groove to slide relative to each other, thereby adjusting the feeding speed of the rubber material. By setting up four sets of discharge grooves that are evenly distributed, the uniform feeding operation of the rubber material is achieved.

[0020] 4. By setting up a vacuum suction cup, the base slides and drives the thin plate head at the top of the vacuum suction cup to move. The vacuum suction cup uses negative pressure to counteract the stickiness of the glue, ensuring that the plate head will not be deformed due to glue adhesion and being rolled into the glue roller during the aluminum plate coating process. The vacuum-adsorbed thin plate continues to move forward with the coating mechanism. At the same time, because the suction mechanism moves forward, it will increase the distance between the subsequent active roller group and the non-powered roller, creating a support gap. Therefore, three sets of folding rods are set up to provide support for the subsequent movement. It should be noted that the surface of the thin plate has a certain degree of hardness. As long as the thin plate head is not stuck into the glue roller, it will not deform due to adhesion during the glue application process. Attached Figure Description

[0034] Based on the above structure, the base 5 slides, driving the thin plate head at the top of the vacuum suction cup 9 to move. The vacuum suction cup 9 uses negative pressure to counteract the adhesiveness of the glue, ensuring that the plate head will not be deformed due to glue adhesion and rolling into the glue roller during the aluminum plate gluing process. It should be noted that... Figure 4 As shown, when the adsorption mechanism moves forward, the distance between the subsequent active roller group 18 and the unpowered roller 10 increases, creating a gap in the support.

Above the connection between the coating roller 19 and the metal roller 20, a feeding hopper 21 is fixedly connected to the inner wall of the coating frame 1. A feeding frame 22 is fixedly connected to the outer wall of the coating frame 1. During operation, the operator places the thin plate on the feeding frame 22. The active roller group 18 pushes the thin plate to one side of the positioning block 12 in the coating frame 1. Then, the coating roller 19 applies glue to the outer wall of the thin plate through the metal roller 20, thus realizing the glue application operation on the thin plate.

During operation, the stirring motor 2101 drives two sets of symmetrical stirring plates 2103 to rotate through the rotating shaft 2102. The rotation of the spiral stirring plates 2103 realizes the stirring operation of the adhesive material and avoids the adhesive material from sticking. Then, the feeding speed of the adhesive material is adjusted. The servo motor 2105 drives the lifting slider through the threaded rod 2106. 2107 slides along the outer wall of the feeding hopper 21. The sliding of the lifting slider 2107 drives the two sets of adjusting support rods 2108 to move synchronously, so that the lifting slider 2107 slides through the adjusting support rods 2108 to drive the adjusting groove plate 2112 connected to one end of the slider 2109 to slide along the inner wall of the limiting guide groove 2113. The sliding of the adjusting groove plate 2112 drives the connecting groove 2114 to slide relative to the discharge groove 2115, thereby adjusting the feeding speed of the rubber material.

The mixing plates 2103 are spiral in shape. During operation, the mixing motor 2101 drives the two sets of symmetrical mixing plates 2103 to rotate through the rotating shaft 2102. The rotation of the spiral mixing plates 2103 realizes the mixing operation of the adhesive material and avoids the adhesive material from sticking together.

[0040] For further details, please refer to [link / reference]. Figures 6 to 7The lengths of the connecting groove 2114 and the discharge groove 2115 are equal. There are four sets of discharge grooves 2115, which are equidistantly distributed along the bottom of the feeding groove plate 2104. During operation, the lifting slider 2107 slides through the adjusting support rod 2108 to drive the adjusting groove plate 2112 at one end of the connecting slider 2109 to slide along the inner wall of the limiting guide groove 2113. The sliding of the adjusting groove plate 2112 causes the connecting groove 2114 and the discharge groove 2115 to slide relative to each other, thereby adjusting the feeding speed of the rubber material. By setting four sets of discharge grooves 2115 that are equidistantly distributed, the uniform feeding operation of the rubber material is achieved.

[0041] For further details, please refer to [link / reference]. Figures 8 to 10 An adjusting cylinder 2201 is screwed to the bottom end of the feeding frame 22. A telescopic plate 2202 is screwed to the output end of the adjusting cylinder 2201. A first fixed roller 2203 is screwed to the outer wall of the telescopic plate 2202. Telescopic groove plates 2204 are fixedly connected to both ends of the telescopic plate 2202. A first connecting rod 2205 is screwed to one end of the first fixed roller 2203. A first connecting plate 2206 is screwed to the outer wall of the first connecting rod 2205. A second connecting rod 2207 is screwed to the bottom end of the first connecting rod 2205. A second connecting plate 2208 is screwed to the outer wall of the second connecting rod 2207. An intermediate roller 2209, which slides and connects to the inner wall of the telescopic groove plate 2204, is screwed to the top end of the second connecting rod 2207. A second fixed roller 2210 is screwed to the top end of the feeding frame 22. A limiting hole groove 2211, which is fixedly connected to the top end of the feeding frame 22, is sleeved on the outer wall of the telescopic groove plate 2204. During operation, the adjustment... The operation of cylinder 2201 drives the telescopic groove plate 2204 on the outer wall of telescopic plate 2202 to slide along the inner wall of the limiting hole groove 2211, so that the telescopic plate 2202 drives the first fixed roller 2203 to move relative to the second fixed roller 2210 at the top of the feeding frame 22. At the same time, the movement of the first fixed roller 2203 drives the intermediate roller 2209 to slide along the inner wall of the telescopic groove plate 2204 through the first connecting rod 2205 and the second connecting rod 2207. By setting the first connecting plate 2206 and the second connecting plate 2208, the three sets of intermediate rollers 2209 slide at equal distances along the inner wall of the telescopic groove plate 2204, realizing the adjustment of the telescopic length of the telescopic groove plate 2204. It should be noted that by telescopically extending and retracting the telescopic groove plate 2204, thin plates of different lengths can be fed efficiently, avoiding the problem that the thin plates are too long, causing them to bend under force, and the thin plates are too short, causing the feeding frame 22 to occupy a large area.

[0042] For further details, please refer to [link / reference]. Figures 8 to 10The telescopic groove plate 2204 forms a telescopic structure with the telescopic plate 2202 and the limiting hole groove 2211. The first connecting plate 2206, the second connecting plate 2208 and the telescopic groove plate 2204 are parallel. The first connecting rod 2205 and the second connecting rod 2207 are distributed in a "V" shape. During operation, the adjusting cylinder 2201 drives the telescopic groove plate 2204 on the outer wall of the telescopic plate 2202 to slide along the inner wall of the limiting hole groove 2211, so that the telescopic plate 2202 drives the first fixed roller 2203 to move relative to the second fixed roller 2210 at the top of the feeding frame 22, thereby adjusting the telescopic length of the telescopic groove plate 2204.

[0043] For further details, please refer to [link / reference]. Figure 9 and Figure 10 The intermediate rollers 2209 are provided in three sets. The three sets of intermediate rollers 2209 form an equidistant telescopic structure with the telescopic groove plate 2204 through the first connecting rod 2205 and the second connecting rod 2207. During operation, the movement of the first fixed roller 2203 drives the intermediate rollers 2209 to slide along the inner wall of the telescopic groove plate 2204 through the first connecting rod 2205 and the second connecting rod 2207. By setting the first connecting plate 2206 and the second connecting plate 2208, the three sets of intermediate rollers 2209 are driven to slide equidistantly along the inner wall of the telescopic groove plate 2204, so as to avoid deformation of the thin plate during feeding.

[0044] The working principle of this invention is as follows: In use, the automatic adhesive coating device for adsorption-type substrates first adjusts the distance between the first fixed roller 2203 and the second fixed roller 2210. The adjusting cylinder 2201 drives the telescopic groove plate 2204 on the outer wall of the telescopic plate 2202 to slide along the inner wall of the limiting hole groove 2211. This causes the telescopic plate 2202 to drive the first fixed roller 2203 to move relative to the second fixed roller 2210 at the top of the feeding frame 22. Simultaneously, the movement of the first fixed roller 2203 is transmitted through the first connecting rod 2205 and... The second connecting rod 2207 drives the intermediate roller 2209 to slide along the inner wall of the telescopic groove plate 2204. By setting the first connecting plate 2206 and the second connecting plate 2208, the three sets of intermediate rollers 2209 slide at equal intervals along the inner wall of the telescopic groove plate 2204, thereby realizing the adjustment of the telescopic length of the telescopic groove plate 2204. It should be noted that by telescopically extending and retracting the telescopic groove plate 2204, thin plates of different lengths can be fed efficiently, avoiding the problem that the thin plates are too long, causing them to bend under stress, and the thin plates are too short, causing the feeding frame 22 to occupy a large area.

[0045] Next, the staff pours the adhesive into the feeding hopper 21. Then, the stirring motor 2101 drives two sets of symmetrical stirring plates 2103 to rotate through the rotating shaft 2102. The rotation of the spiral stirring plates 2103 achieves the stirring operation of the adhesive and prevents the adhesive from sticking together.

[0046] Next, the feeding speed of the rubber compound is adjusted. The servo motor 2105 drives the lifting slider 2107 to slide along the outer wall of the feeding hopper 21 via the threaded rod 2106. The sliding of the lifting slider 2107 drives the two sets of adjusting support rods 2108 to move synchronously. This causes the lifting slider 2107 to slide along the inner wall of the adjusting groove 2112 connected to one end of the slider 2109 via the adjusting support rods 2108. The sliding of the adjusting groove 2112 causes the connecting groove 2114 to slide relative to the discharge groove 2115, thereby adjusting the feeding speed of the rubber compound. By setting four sets of discharge grooves 2115 that are equally distributed, the uniform feeding operation of the rubber compound is achieved.

[0047] Next, the worker places the sheet on the feeding frame 22, and the active roller group 18 pushes the sheet to one side of the positioning block 12 in the glue coating frame 1. Then, the glue coating roller 19 applies glue to the outer wall of the sheet through the metal roller 20.

[0048] Finally, the vacuum suction cup 9 works to adsorb the thin plate head onto its top. Simultaneously, the electric push cylinder 11 drives the positioning stop 12 to retract, and the drive motor 2, through the ball screw 3, drives the base 5 at the top of the ball slider 4 to slide along the outer wall of the support rail 6. The sliding of the base 5 causes the thin plate head at the top of the vacuum suction cup 9 to move. When the vacuum suction cup 9 passes through the coating roller 19, the negative pressure counteracts the adhesiveness of the glue, allowing the thin plate head to pass smoothly through the coating roller 19. This ensures that during the aluminum plate coating process, the thin plate head will not be deformed due to glue adhesion and being rolled into the roller. When the unpowered support roller 10 is located at the center of the coating roller 19, it stops moving forward. At the same time, the conveying gap caused by the vacuum-adsorbed thin plate's movement is filled by three sets of folding rods 14. It should be noted that because of the adsorption... When the mechanism moves forward, the distance between the subsequent active roller group 18 and the non-powered roller 10 increases, creating a gap for support. Therefore, three sets of folding rods 14 are set to provide support for the subsequent movement. The thin plate continues to move forward under the action of the glue coating roller 19. When the sensor detects that the tail of the thin plate has passed smoothly, the pneumatic push cylinder 7 works to drive the pneumatic lifting platform 8 to retract. At the same time, the drive motor 2 drives the vacuum suction cup 9 to follow the glue coating mechanism backward. After reaching the starting position, the pneumatic push cylinder 7 works to drive the pneumatic lifting platform 8 to lift. At the same time, the electric push cylinder 11 drives the positioning block 12 to slide upward along the outer wall of the vacuum suction cup 9. It should be noted that the surface of the thin plate has a certain hardness. As long as the head of the thin plate is not stuck into the glue roller, it will not deform due to adhesion during the glue application process.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
