Description

Technical Field

[0001] The utility model relates to the technical field of double-sided adhesive tape production, in particular to a double-sided adhesive tape laminating device. Background Art

[0002] In the preparation process of electronic products, printed circuit boards are widely used as the support of electronic components. In order to fix and share the ground with the entire system of the electronic product, double-sided tape or double-sided conductive tape needs to be attached to the back of the printed circuit board.

[0003] After searching, the utility model with Chinese patent publication number CN112457799A discloses a waterproof conductive double-sided adhesive, including superimposed double-sided adhesive bodies, heating wires, and metal wire meshes, and also includes a micro temperature control system connected to both ends of the heating wires; the micro temperature control system includes a connected power supply, a heating wire ICH, a heating wire BMC, a resistor R3110, a temperature sensor, and a controller.

[0004] As mentioned above, after the double-sided tape is produced, it needs to be coated on both sides. However, when feeding the film, the dust in the processing environment is easily attached to the isolation film, which will cause bubbles to appear at the junction of the isolation film and the substrate. In addition, the dust attached to the surface of the double-sided tape will also affect the product quality. Utility Model Content

[0005] The purpose of the utility model is to provide a double-sided adhesive laminating device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-sided adhesive laminating device, comprising a base plate, characterized in that: a mounting plate 1 is fixedly connected to both ends of the top outer wall of the base plate, and two mounting plates 1 are installed with two symmetrically arranged cleaning components, and the cleaning components include two horizontal plates fixedly connected to the outer walls of one side of the two mounting plates, and the same mounting roller is rotatably connected between the two horizontal plates, and the circumferential outer wall of the mounting roller is sleeved with a cleaning cloth, and the outer wall of one end of one of the horizontal plates is rotatably connected to two gears, and the mounting roller and one of the gears are coaxially fixed, and the same adhesive roller is rotatably connected between the two horizontal plates, and the adhesive roller and the cleaning cloth are in contact with each other.

[0007] As a further preferred embodiment of the technical solution, two guide rollers are rotatably connected between the two mounting plates, and the outer wall at one end of one of the mounting plates is rotatably connected to two transmission wheels, and the two transmission wheels are coaxially fixed to the two guide rollers respectively, and a driven wheel is coaxially fixed to the outer wall at one end of the other gear, and the transmission wheel and the driven wheel are provided with the same belt.

[0008] The film layer and the adhesive layer can be cleaned once before they are bonded together, so as to avoid dust attached to the surface of the film layer remaining on the surface of the double-sided adhesive, which is beneficial to improving the quality of the double-sided adhesive. When the film layer is transmitted, it drives a guide roller to rotate, and the guide roller drives a transmission wheel to rotate. The transmission wheel can drive the driven wheel to rotate through the belt, and the driven wheel drives a gear to rotate. This gear can drive another gear to rotate in the opposite direction through meshing, and the other gear can also drive the installation roller to rotate. The external cleaning cloth can be cleaned before the film layer and the adhesive layer are bonded together, and the adhesive roller bonded to the cleaning cloth can rotate synchronously with it, so as to clean the dust on the surface of the cleaning cloth, thereby extending the service life of the cleaning cloth.

[0009] As a further preferred embodiment of the present technical solution, two mounting plates 2 are fixedly connected to both ends of the top outer wall of the bottom plate, and the two mounting plates 2 are installed with the same extrusion assembly, which is located on one side of the cleaning assembly.

[0011] As a further preferred embodiment of the present technical solution, a rubber layer and two film layers are placed between the two pressure rollers, and the two film layers are respectively surrounded by the outside of the two guide rollers.

[0012] The device can adapt to the processing of double-sided tapes of different thicknesses, so that the two film layers and the adhesive layer can fit closely together, and the distance between the two pressure rollers is adjusted according to the thickness of the double-sided tape. The wheel disc is used to drive the screw rod to rotate. Because the mounting block is restricted by the limit groove, the driving rod is connected to the mounting block, and the position of the moving block is also restricted and cannot rotate. Therefore, the rotation of the screw rod can drive the moving block to one side, and the moving block can drive the two mounting blocks to move closer to or away from each other through the driving rod, and the positions of the two pressure rollers will also change accordingly, so that the two pressure rollers can positively press the two film layers and the adhesive layer to fit each other.

[0015] (1) The utility model provides a dust cleaning component, which can be cleaned once before the film layer and the adhesive layer are bonded together, so as to prevent dust attached to the surface of the film layer from being left on the surface of the double-sided adhesive, which is beneficial to improving the quality of the double-sided adhesive. When the film layer is transmitted, it drives a guide roller to rotate, and the guide roller drives a transmission wheel to rotate. The transmission wheel can drive a driven wheel to rotate through a belt, and the driven wheel drives a gear to rotate. This gear can drive another gear to rotate in the opposite direction through meshing, and the other gear can also drive the installation roller to rotate. The external dust cleaning cloth can also be cleaned once before the film layer and the adhesive layer are bonded together, and the adhesive roller bonded to the dust cleaning cloth can rotate synchronously with it, so that the dust on the surface of the dust cleaning cloth can be cleaned, making the service life of the dust cleaning cloth longer.

[0016] (2) The utility model sets an extrusion component so that the device can adapt to the processing of double-sided adhesive tapes of different thicknesses, so that the two film layers and the adhesive layer can fit tightly together, and the distance between the two pressure rollers is adjusted according to the thickness of the double-sided adhesive tape. The wheel disc is used to drive the screw rod to rotate. Since the mounting block is restricted by the limit groove, the driving rod is connected to the mounting block, and the position of the moving block is also restricted and cannot rotate. Therefore, the rotation of the screw rod can drive the moving block to move to one side, and the moving block can drive the two mounting blocks to move closer to or away from each other through the driving rod, and the positions of the two pressure rollers will also change accordingly, so that the two pressure rollers can positively press the two film layers and the adhesive layer to fit each other.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a technical solution: Figure 2 and Figure 4 As shown, in this embodiment, a double-sided adhesive laminating device includes a base plate 1, characterized in that: a mounting plate 2 is fixedly connected to both ends of the top outer wall of the base plate 1, and two mounting plates 2 are installed with two symmetrically arranged cleaning components 7, and the cleaning components 7 include two transverse plates 701 fixedly connected to the outer walls of one side of the two mounting plates 2, and the same mounting roller 702 is rotatably connected between the two transverse plates 701, and the circumferential outer wall of the mounting roller 702 is sleeved with a cleaning cloth 703, and the outer wall of one end of one of the transverse plates 701 is rotatably connected to two gears 704, and the mounting roller 702 and one of the gears 704 are coaxially fixed, and the same adhesive roller 708 is rotatably connected between the two transverse plates 701, and the adhesive roller 708 and the cleaning cloth 703 are in contact with each other.

[0025] Two guide rollers 4 are rotatably connected between the two mounting plates 2, and the outer wall at one end of one mounting plate 2 is rotatably connected to two transmission wheels 705, and the two transmission wheels 705 are coaxially fixed to the two guide rollers 4 respectively, and a driven wheel 706 is coaxially fixed to the outer wall at one end of the other gear 704, and the transmission wheel 705 and the driven wheel 706 are sleeved with the same belt 707.

[0026] When the film layer 5 is transmitted, it drives a guide roller 4 to rotate, and the guide roller 4 drives a transmission wheel 705 to rotate. The transmission wheel 705 can drive the driven wheel 706 to rotate through the belt 707, and the driven wheel 706 drives a gear 704 to rotate. This gear 704 can drive another gear 704 to rotate in the opposite direction through meshing, and the other gear 704 can also drive the installation roller 702 to rotate, and the cleaning cloth 703 on the outside can be cleaned before the film layer 5 and the adhesive layer 6 are bonded, and the adhesive roller 708 bonded to the cleaning cloth 703 can rotate synchronously with it, so as to clean the dust on the surface of the cleaning cloth 703, thereby extending the service life of the cleaning cloth 703.

[0027] like Figure 3 and Figure 5 As shown, two mounting plates 2 3 are fixedly connected at both ends of the top outer wall of the bottom plate 1 , and the two mounting plates 2 3 are installed with the same extrusion component 8 , which is located on one side of the dust cleaning component 7 .

[0028] The extrusion assembly 8 includes two limit grooves 801 opened in the two mounting plates 23, and two mounting blocks 802 are slidably connected in the two limit grooves 801. The same pressure roller 806 is rotatably connected between the two mounting blocks 802. One side of the two mounting blocks 802 is rotatably connected to a driving rod 803, and one end of the two driving rods 803 is rotatably connected to the same moving block 805. A screw rod 804 is threadedly connected in the moving block 805, and one end of the screw rod 804 is rotatably connected to the inner wall of one side of the mounting plate 23.

[0029] A rubber layer 6 and two film layers 5 are placed between the two pressing rollers 806 , and the two film layers 5 are respectively wrapped around the outside of the two guide rollers 4 .

[0030] The distance between the two pressure rollers 806 is adjusted according to the thickness of the double-sided tape, and the wheel is used to drive the screw rod 804 to rotate. Since the mounting block 802 is restricted by the limit groove 801, the driving rod 803 is connected to the mounting block 802, and the position of the moving block 805 is also restricted and cannot rotate. Therefore, the rotation of the screw rod 804 can drive the moving block 805 to move to one side, and the moving block 805 can drive the two mounting blocks 802 to move closer to or away from each other through the driving rod 803, and the positions of the two pressure rollers 806 will also change accordingly, so that the two pressure rollers 806 can positively press the two film layers 5 and the adhesive layer 6 to fit each other.

[0031] like Figure 1 and Figure 2 As shown, the transmission ratio between the driving wheel 705 and the driven wheel 706 is less than one, and one rotation of the driving wheel 705 can drive the driven wheel 706 to rotate multiple times, and then the mounting roller 702 will also be driven to rotate quickly, thereby further improving the dust cleaning effect.

[0032] The utility model provides a double-sided adhesive laminating device, and the specific working principle is as follows:

[0033] When the device is working, the distance between the two pressure rollers 806 is first adjusted according to the thickness of the double-sided adhesive tape, and the wheel disc is used to drive the screw rod 804 to rotate. Because the mounting block 802 is restricted by the limit groove 801, the driving rod 803 is connected to the mounting block 802, and the position of the moving block 805 is also restricted and cannot rotate. Therefore, the rotation of the screw rod 804 can drive the moving block 805 to move to one side, and the moving block 805 can drive the two mounting blocks 802 to move closer to or away from each other through the driving rod 803, and then the positions of the two pressure rollers 806 will change accordingly, so that the two pressure rollers 806 can positively press the two film layers 5 and the adhesive layer 6 to fit each other. After the two film layers 5 and the adhesive layer 6 are placed, the external winding device is started. The two film layers 5 and the adhesive layer 6 will also start to transmit. When the film layer 5 transmits, it drives a guide roller 4 to rotate, and the guide roller 4 drives a transmission wheel 705 to rotate. The transmission wheel 705 can drive a driven wheel 706 to rotate through a belt 707, and the driven wheel 706 drives a gear 704 to rotate. This gear 704 can drive another gear 704 to rotate in the opposite direction through meshing, and the other gear 704 can also drive the installation roller 702 to rotate, and the cleaning cloth 703 on the outside can be cleaned before the film layer 5 and the adhesive layer 6 are attached, and the adhesive roller 708 attached to the cleaning cloth 703 can rotate synchronously with it, so as to clean the dust on the surface of the cleaning cloth 703, thereby extending the service life of the cleaning cloth 703.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
