[0030] like Figures 1 to 7 As shown, the present invention is a bonding device for adhesive production, comprising: a machine 1; an adhesive conveying mechanism 101 arranged on the machine 1 for adhesive rolling, it should be noted that the adhesive conveying mechanism 101 belongs to the prior art and will not be elaborated on; an electric push rod 2 fixedly mounted on the machine 1; a glue applicator 3 fixedly mounted at the output end of the electric push rod 2; a conveying component 4 arranged on the machine 1 for conveying adhesive products; a cleaning component 5 for cleaning the surface of the adhesive product; and a rolling component 7 for pressing the adhesive on the surface of the product after the adhesive is completed;

[0031] The conveying assembly 4 includes: a box placing plate 401 slidably mounted on the machine table 1; a connecting plate 402 fixedly mounted on the box placing plate 401; an electric cylinder 403 driving the connecting plate 402 to move; and protrusions 4011 fixedly mounted around the box placing plate 401;

[0032] When it is necessary to glue the product, the product is placed on the placement box plate 401, and the electric cylinder 403 is started. The output end of the electric cylinder 403 contracts, driving the placement box plate 401 to move downward to the glue applicator 3. Then, the output end of the electric push rod 2 pushes the glue applicator 3 down, and the adhesive on the adhesive conveying mechanism 101 is pressed against the surface of the product on the placement box plate 401. After heating and maintaining pressure, the adhesive bonding is completed.

[0033] The cleaning component 5 includes: a dust blowing head 501 for cleaning the surface of the product; a fixed part 502 connected to the dust blowing head 501, and the fixed part 502 is fixedly installed on the machine 1; a movable part 503 movably penetrating the fixed part 502; a piston 504 fixedly installed on the movable part 503, and the side wall of the piston 504 is tightly fitted with the inner wall of the fixed part 502; a pressure plate 505 fixedly installed on the movable part 503, and the top of the pressure plate 505 is placed on the bottom of the output end of the electric push rod 2. It should be added here that in order to improve the stability of the movement of the pressure plate 505, one end of the pressure plate 505 is slidably installed on the machine 1; a first spring 506 mounted on the movable part 503 to drive it to reset, and a centering component 6 for centering the product to be glued.

[0034] When the output end of the electric push rod 2 pushes the glue applicator 3 to descend, the electric push rod 2 delivers extrusion to drive the pressure plate 505 fixed on the movable part 503 to move downward, so that the piston 504 fixed on the movable part 503 squeezes the air inside the fixed part 502, and the air is discharged through the dust blowing head 501 to blow away the dust on the surface of the product placed on the box plate 401, reducing the dust adhering to the product, thereby improving the firmness of the adhesive bonding.

[0035] It should be added here that one end of the first spring 506 is fixedly connected to the bottom of the pressure plate 505, and the other end of the first spring 506 is fixedly connected to the top of the fixing member 502; when the output end of the electric push rod 2 moves upward and resets, the first spring 506 elastically resets after being subjected to force, pushing the pressure plate 505 fixed on the moving member 503 to move upward, thereby realizing the upward movement and reset of the moving member 503.

[0036] In the actual practical process, in order to avoid the product being placed crookedly during product gluing, which causes the adhesive backing to be offset and affects the gluing quality, the centering component 6 includes: two positioning plates 601 symmetrically and slidably mounted on the placement box plate 401; a rack 602 fixedly connected to the positioning plate 601; a gear shaft 603 meshing with the rack 602, and both ends of the gear shaft 603 are rotatably mounted on the placement box plate 401; an extrusion rod 604 that drives the positioning plate 601 to move; and a second spring 605 mounted on the extrusion rod 604 to drive it to return to its original position.

[0037] When the moving part 503 moves downward, the circular bottom of the moving part 503 is pressed on the trapezoidal surface at one end of the squeezing rod 604, so that the squeezing rod 604 drives the positioning plate 601 fixed thereto to move, so that the rack 602 fixed on the positioning plate 601 engages with the gear shaft 603, and the gear shaft 603 drives the rack 602 on the other positioning plate 601 to engage, and the two symmetrical positioning plates 601 move relative to each other, automatically centering the product placed on the box plate 401, improving the pasting accuracy of the product adhesive, avoiding skewed pasting of the adhesive, and affecting the pasting quality of the adhesive.

[0038] It should be noted here that a positioning block 606 is mounted on the extrusion rod 604, and the top of the positioning block 606 is fixedly mounted on the box placement plate 401, one end of the second spring 605 is fixedly mounted on the surface of one end of the extrusion rod 604, and the other end of the second spring 605 is fixedly connected to the surface of the positioning block 606; when one end of the extrusion rod 604 is released from the extrusion of the moving part 503, the second spring 605 elastically returns to its original position after being subjected to force, pushing the extrusion rod 604 to move and return to its original position, and driving the rack 602 fixed on the positioning plate 601 to engage with the gear shaft 603, so that the two positioning plates 601 move in opposite directions, automatically releasing the centering positioning of the product.

[0039] It should be added here that one end of the extrusion rod 604 is set to a trapezoid, and the bottom of the movable member 503 is set to a circle that matches the trapezoid at one end of the extrusion rod 604; when the movable member 503 moves downward, the circle at the bottom of the movable member 503 and the trapezoid at one end of the extrusion rod 604 are set to reduce the contact area between the two, reduce friction, and facilitate pushing the extrusion rod 604 to move.

[0040] It should be added here that a through slot 102 is opened on the machine 1, and the through slot 102 is located directly below the moving member 503; when the moving member 503 descends, the bottom of the moving member 503 will move into the through slot 102 to prevent the moving member 503 from contacting with the machine 1 and causing interference.

[0041] In order to prevent the adhesive backing from being loosely adhered and having the risk of falling off, the rolling assembly 7 includes: a bracket 701 fixedly mounted on the machine 1; a guide rod 702 symmetrically movable and penetrating the bracket 701; a pressure roller 703 rotatably mounted on the two guide rods 702; and a third spring 704 sleeved on the guide rods 702. It should be added that a fixed block is fixedly mounted on the guide rod 702, one end of the pressure roller 703 is rotatably mounted on the corresponding fixed block, and one end of the third spring 704 is fixedly connected to the top of the bracket 701, and the other end of the third spring 704 is fixedly connected to the surface of the fixed block.

[0042] After the product is pasted with adhesive backing, the electric push rod 2 drives the adhesive applicator 3 to move up and reset. At this time, the first spring 506 drives the moving part 503 to move up and reset, and the positioning block 606 drives the extrusion rod 604 to reset, so that the two positioning plates 601 automatically release the positioning of the product, and then the output end of the electric cylinder 403 drives the placement box plate 401 to move to the loading and unloading area. When the arc surfaces of the two symmetrical protrusions 4011 at one end of the placement box plate 401 are pressed on the corresponding bottom of the guide rod 702, the guide rod 702 is pushed up, so that the guide rod 702 drives the pressure roller 703 to move up, and the anti-static The pressure-stop roller 703 interferes with the conveyed product. When the protrusion 4011 releases the pressure on the guide rod 702, the third spring 704 pushes the guide rod 702 downward, causing the pressure roller 703 to return to its original position, and tightly rolls the adhesive on the surface of the product that continues to be conveyed to prevent the adhesive from being loosely adhered and having the risk of falling off, thereby improving the firmness of the adhesive. After the box plate 401 is moved into place, the two symmetrical protrusions 4011 at the other end of the box plate 401 squeeze the guide rod 702 again to move the guide rod 702 upward, making it easier for the user to remove the product.

[0043] Avoid the pressure roller 703 affecting the movement of the product on the box plate 401 during product pushing;

[0044] The protrusion 4011 is set to be arc-shaped, and the bottom of the guide rod 702 is set to be an arc surface that matches the protrusion 4011; when the output end of the electric cylinder 403 pushes the connecting plate 402 fixed on one side of the placement box plate 401 to move and reset, the two symmetrical protrusions 4011 on both sides of the placement box plate 401 squeeze the bottom of the guide rod 702, so that the guide rod 702 moves upward, so that when the placement box plate 401 drives the surface product to move to the loading and unloading area, the guide rod 702 can drive the pressure roller 703 to move upward, and will not affect the transportation of the product.

[0045] Working principle: Turn on the power supply. When the product needs to be glued, place the product on the placement box plate 401, start the electric cylinder 403, and the output end of the electric cylinder 403 contracts, driving the placement box plate 401 to move to the bottom of the glue applicator 3. Then, the output end of the electric push rod 2 pushes the glue applicator 3 down, and presses the adhesive on the adhesive conveying mechanism 101 onto the surface of the product on the placement box plate 401 to attach the adhesive. When the output end of the electric push rod 2 pushes the glue applicator 3 down, the electric push rod 2 conveys and squeezes to drive the fixed pressure plate 505 on the moving part 503 to move downward, so that the fixed piston 504 on the moving part 503 squeezes the air inside the fixed part 502, and the air is discharged through the dust blowing head 501 to blow away the dust on the surface of the product placed on the placement box plate 401, thereby reducing the dust adhering to the product.

[0046] When the moving member 503 moves downward, the circular bottom of the moving member 503 is pressed on the trapezoidal surface at one end of the squeezing rod 604, so that the squeezing rod 604 drives the positioning plate 601 fixed thereto to move, so that the rack 602 fixed on the positioning plate 601 is meshed with the gear shaft 603, and the gear shaft 603 drives the rack 602 on the other positioning plate 601 to mesh, and the two symmetrical positioning plates 601 move relatively to center the product placed on the box plate 401, thereby improving the pasting accuracy of the product adhesive and preventing the adhesive from being pasted crookedly;

[0047] After the product is pasted with adhesive, the electric push rod 2 drives the glue applicator 3 to move up and reset. At this time, the first spring 506 drives the moving member 503 to move up and reset, and the positioning block 606 drives the extrusion rod 604 to reset, so that the two positioning plates 601 automatically release the positioning of the product, and then the output end of the electric cylinder 403 pushes the box placement plate 401 to move to the loading and unloading area. When the arc surface of the two symmetrical protrusions 4011 at one end of the box placement plate 401 is squeezed at the bottom of the corresponding guide rod 702, the guide rod 702 is pushed up, so that the guide rod 702 drives the extrusion rod 604 to reset. When the cam 401 is in place, the two symmetrical cams 4011 at the other end of the cam plate 401 squeeze the guide rod 702 again and move the guide rod 702 upwards, making it easier for the user to remove the product.
