Description

Technical Field

[0001] This application relates to the field of die-cutting machine technology, specifically to a die-cutting and bonding device. Background Technology

[0002] With the rapid development of the LCD screen manufacturing industry, new products are constantly evolving towards thinner and lighter designs. Larger components that originally served functions such as fixing, insulation, and conductivity have been replaced by thinner and lighter die-cut products such as tapes and polyester films. Many processes in the production of die-cut products require the lamination of materials such as polyester films to achieve effects such as fixing and insulation. In traditional die-cutting production operations, the film needs to be applied to the designated position on the product. Usually, tension rollers and blades are used to apply the material to be laminated to the base layer.

[0003] An existing patent (publication number: CN 222681995U) discloses a die-cutting and bonding device, belonging to the field of die-cutting machine technology. It includes a die-cutting machine with a patching mechanism installed on one side. Above the patching mechanism on the other side of the die-cutting machine, a bonding mechanism is located. The bonding mechanism includes a strip roller, a take-up roller, and a roller support. A fastening blade is installed below the take-up roller on the side surface of the roller support. On the other side of the die-cutting machine, a pressing mechanism is located. The pressing mechanism includes a mounting plate, a pressing roller, and a pressing motor. A lifting guide rod is installed inside the pressing mechanism on one side of the mounting plate, and a reciprocating screw is installed inside the pressing mechanism on one end of the lifting guide rod. The pressing roller rotates using a bearing connected to the mounting plate and the lifting guide rod. The pressing motor drives the pressing roller to rotate, thus controlling the rotating pressing roller to press the bonding layer and the base layer together, avoiding excessive force at both ends of the bonding layer, which could lead to excessive distance in the middle and air bubbles.

[0004] While the device in the aforementioned comparative document solves the problem of loose bonding and air bubbles that can easily occur when using a control blade to apply pressure and fix the material, it lacks a cleaning structure and heating function. When applying the film to the material, it cannot automatically clean the dust on the material surface in advance, requiring manual cleaning which is time-consuming and labor-intensive. At the same time, it cannot gather heat to activate the adhesive layer, resulting in low bonding strength. To solve the above problems, a die-cutting bonding device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a die-cutting and bonding device with advantages such as a cleaning structure and heating function. This solves the problems of not being able to automatically clean dust from the material surface before bonding materials, not being able to gather and heat-activate the adhesive layer, and having low bonding strength.

[0006] To achieve the above objectives, this application provides the following technical solution: a die-cutting and bonding device, including a support frame, wherein a conveying structure is provided inside the support frame, and a U-shaped support plate and an adjusting support frame are fixedly connected to the top of the support frame; The top of the U-shaped support plate is fixedly connected to a first electric push rod and two first retracting rods. The first electric push rod is located between the two first retracting rods. An adhesive mechanism is fixedly connected to the bottom of the first electric push rod and the first retracting rods. The top of the adhesive mechanism is fixedly connected to a second electric push rod and two second retracting rods. The bottom of the second electric push rod and the second retracting rods is fixedly connected to a second U-shaped plate. A pressing wheel is movably connected inside the second U-shaped plate via a pin. An electric heating tube is fixedly connected inside the pressing wheel. Two connecting rods are fixedly connected to the side of the adhesive mechanism. A fixing frame is fixedly connected to the side of the two connecting rods. Multiple elastic retracting rods are fixedly connected to the top of the fixing frame. The bottom of the elastic retracting rods is fixedly connected to a first U-shaped plate. Multiple rollers are movably connected inside the first U-shaped plate via pins. A cleaning cloth is covered on the surface of the rollers.

[0007] The above solution, by setting a second electric push rod, operates during the film application process, pushing the extrusion roller downwards. The extrusion roller's surface contacts the material, applying pressure to complete the bonding. Mechanical pressure eliminates air bubbles, ensuring a smooth, wrinkle-free bonding surface. An electric heating element embedded inside the extrusion roller heats the contact area, softening the adhesive layer and increasing adhesion. An elastic retraction rod allows the cleaning roller to adapt to the unevenness of the material surface, maintaining constant contact pressure. The roller and cleaning cloth rotate as the material moves, wiping away dust and oil stains from the material surface, thus improving bonding quality.

[0008] Furthermore, multiple protrusions are fixedly connected to the surface of the roller.

[0009] The above method, by setting up bumps and forming regular raised textures on the roller surface, can increase the friction between the cleaning cloth and the material, thus preventing the cloth from shifting its position.

[0010] Furthermore, the cleaning cloth is fixedly connected with Velcro tabs and Velcro tabs on opposite sides respectively.

[0011] The above method allows the two ends of the cleaning cloth to be connected by attaching the Velcro tabs to the roller surface, thus fixing the cleaning cloth to the roller surface and enabling quick replacement of the cleaning cloth.

[0012] Furthermore, the adjustment support frame has two through holes inside, a connecting plate is slidably connected inside the through holes, an L-shaped movable frame is fixedly connected to the bottom of the connecting plate, and a guide wheel is movably connected to the top of the L-shaped movable frame through a pin.

[0013] The above scheme uses through holes to constrain the movement path of the connecting plate and ensure the straightness of the lateral adjustment. By setting an L-shaped movable frame, the material edge can be guided to prevent the conveyor from deviating. By setting guide wheels, friction between the material and the adjustment mechanism can be reduced during material conveying, thus avoiding surface scratches.

[0014] Furthermore, both of the L-shaped movable frames are fixedly connected to a drainage plate on their sides.

[0015] The above solution, by setting a diversion plate, can limit the lateral movement range of the material and assist in aligning and fitting the position.

[0016] Furthermore, a dual-axis motor is fixedly connected inside the adjustment support frame, and a threaded rod is fixedly connected to the output end of the dual-axis motor. The shaft end of the threaded rod is rotatably connected to the inner side of the adjustment support frame.

[0017] The above scheme, by setting up a dual-axis motor, allows for symmetrical lateral adjustment of the guide wheel assembly to adapt to changes in material width.

[0018] Furthermore, a threaded cylinder is threadedly connected to the surface of the threaded rod, a movable block is fixedly connected to the surface of the threaded cylinder, and a connecting plate is fixedly connected to the surface of the movable block.

[0019] The above scheme, through the threaded connection between the threaded rod and the threaded cylinder, and through the limiting of the movable block, can convert the rotational motion of the motor into the linear movement of the connecting plate.

[0020] Furthermore, multiple support rods are fixedly connected to the bottom of the support frame.

[0021] The above solution, by setting up support rods, can raise the device's height off the ground, making it easier to clean the space below.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This die-cutting and bonding device applies pressure to the material through the contact between the surface of the extrusion roller and the material. Mechanical pressure eliminates air bubbles, ensuring a smooth and wrinkle-free bonding surface. An electric heating tube embedded inside the extrusion roller heats the contact area, softening the adhesive layer and increasing adhesion. An elastic shrinkage rod allows the cleaning roller to adapt to the undulations of the material surface, maintaining constant contact pressure. The roller and cleaning cloth rotate as the material moves, wiping away dust and oil stains from the material surface and improving bonding quality. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1 , Figure 3 and Figure 5 The die-cutting and bonding device in this embodiment includes a support frame 1, a conveying structure 101 is provided inside the support frame 1, and a U-shaped support plate 2 and an adjusting support frame 3 are fixedly connected to the top of the support frame 1. A first electric push rod 201 and two first retraction rods 202 are fixedly connected to the top of the U-shaped support plate 2. The first electric push rod 201 is located between the two first retraction rods 202. An adhesive mechanism 2012 is fixedly connected to the bottom of the first electric push rod 201 and the first retraction rods 202. A second electric push rod 207 and two second retraction rods 208 are fixedly connected to the top of the adhesive mechanism 2012. A second U-shaped plate 209 is fixedly connected to the bottom of the second electric push rod 207 and the second retraction rods 208. An extrusion wheel is movably connected to the inside of the second U-shaped support plate 209 through a pin. 2010, an electric heating tube 2011 is fixedly connected inside the extrusion roller 2010. Two connecting rods 203 are fixedly connected to the side of the pasting mechanism 2012. A fixing frame 204 is fixedly connected to the side of the two connecting rods 203. Multiple elastic shrinking rods 205 are fixedly connected to the top of the fixing frame 204. A first U-shaped plate 206 is fixedly connected to the bottom of the elastic shrinking rods 205. Multiple rollers 5 are movably connected inside the first U-shaped plate 206 via pins. A cleaning cloth 4 is fitted onto the surface of each roller 5. A second electric push rod 207 is provided to activate during the film application process. Operation 207 pushes the extrusion roller 2010 downwards, allowing it to contact the material and apply pressure for bonding. Mechanical pressure removes air bubbles, ensuring a smooth, wrinkle-free bonding surface. An electric heating element 2011 embedded inside the extrusion roller 2010 heats the contact area, softening the adhesive layer and increasing adhesion. An elastic retraction rod 205 allows the cleaning roller 5 to adapt to the unevenness of the material surface, maintaining constant contact pressure. The roller 5 rotates with the cleaning cloth 4 as the material moves, effectively wiping away dust from the material surface. Dust and oil stains can improve the bonding quality. Multiple protrusions 501 are fixedly connected to the surface of the roller 5. By setting the protrusions 501, a regular raised texture is formed on the surface of the roller 5, which can increase the friction between the cleaning cloth 4 and the material and prevent its position from shifting. The cleaning cloth 4 is fixedly connected to the opposite sides of the cleaning cloth 4 with Velcro 401 and Velcro 402 respectively. By sticking the Velcro 401 and Velcro 402, the two ends of the cleaning cloth 4 can be connected, thereby fixing the cleaning cloth 4 to the surface of the roller 5. At the same time, it can also achieve the purpose of quickly changing the cleaning cloth.

[0027] Please see Figure 1 and Figure 4The adjusting support frame 3 has two through holes 301 inside, and a connecting plate 306 is slidably connected inside the through holes 301. An L-shaped movable frame 307 is fixedly connected to the bottom of the connecting plate 306. A guide wheel 309 is movably connected to the top of the L-shaped movable frame 307 through a pin. By setting the through holes 301, the movement path of the connecting plate 306 can be constrained to ensure the straightness of the lateral adjustment. By setting the L-shaped movable frame 307, the material edge direction can be guided to prevent the conveying from deviating. By setting the guide wheel 309, the friction between the material and the adjusting mechanism can be reduced during material conveying to avoid scratching the surface. A guide plate 308 is fixedly connected to the sides of both L-shaped movable frames 307. By setting the guide plate 308, the lateral movement range of the material can be limited and the alignment and fitting position can be assisted. A double shaft is fixedly connected inside the adjusting support frame 3. The output end of the dual-axis motor 302 is fixedly connected to a threaded rod 303. The shaft end of the threaded rod 303 is rotatably connected to the inner side of the adjusting support frame 3. By setting the dual-axis motor 302, the operation of the dual-axis motor 302 can realize the symmetrical lateral adjustment of the guide wheel 309 group to adapt to changes in material width. The threaded rod 303 is threadedly connected to a threaded cylinder 304. The threaded cylinder 304 is fixedly connected to a movable block 305. The connecting plate 306 is fixedly connected to the surface of the movable block 305. Through the threaded connection between the threaded rod 303 and the threaded cylinder 304, and through the limiting of the movable block 305, the rotational motion of the motor can be converted into the linear movement of the connecting plate 306. Multiple support rods 102 are fixedly connected to the bottom of the support frame 1. By setting the support rods 102, the height of the device above the ground can be raised to facilitate the cleaning of the space below.

[0028] In this embodiment, pressure is applied to the material through the contact between the surface of the extrusion roller 2010 and the material to complete the bonding. Mechanical pressure removes air bubbles, ensuring a smooth and wrinkle-free bonding surface. The electric heating tube 2011 embedded inside the extrusion roller 2010 heats the contact area, softening the adhesive layer and increasing the bonding force. The elastic shrinkage rod 205 allows the cleaning roller 5 to adapt to the undulations of the material surface, maintaining a constant contact pressure. The roller 5 and the cleaning cloth 4 can rotate with the material movement, wiping away dust and oil stains from the material surface and improving the bonding quality. The dual-axis motor 302 restricts the threaded rod 303. The movable block 305 and the through hole 301 limit the movement of the threaded cylinder 304 on the surface of the threaded rod 303, thereby adjusting the distance between the two L-shaped movable frames 307 to adapt to changes in material width and to stably transport materials of different widths.

[0029] The working principle of the above embodiment is as follows: When in use, the first electric push rod 201 runs, which can push the pasting mechanism 2012 to move down. After the movement is completed, people place the material on the top of the conveying structure 101. The conveying structure 101 can transport the material to the bottom of the pasting mechanism 2012. Then the pasting mechanism 2012 runs, which can apply film to the top of the material. When applying film to the material, the second electric push rod 207 runs, which can push the extrusion roller 2010 to move down. The surface of the extrusion roller 2010 contacts the material, and pressure can be applied to complete the bonding. The mechanical pressure removes air bubbles and ensures that the bonding surface is flat and wrinkle-free. The electric heating tube 2011 embedded in the extrusion roller 2010 can heat the contact area, which can soften the adhesive layer and improve the bonding force. By setting the roller 5 and the cleaning cloth 4, they can rotate with the material movement, which can wipe the dust and oil stains on the material surface and improve the bonding quality. When transporting materials, the two L-shaped movable frames 307 can guide the edge of the material to prevent it from deviating from its intended path. The two rows of guide wheels 309 can reduce the friction between the material and the adjustment mechanism, thus avoiding scratches on the surface.
