Description

Technical Field

[0001] The utility model relates to the technical field of membrane switches, in particular to a membrane switch coating device. Background Art

[0002] Membrane switch is an operating system that integrates key functions, indicating elements, and instrument panels. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contact of the upper circuit deforms downward and contacts the plate of the lower circuit. When the finger is released, the contact of the upper circuit rebounds, the circuit is disconnected, and the loop triggers a signal.

[0003] Membrane switches usually need to be coated before leaving the factory. For example, the existing patent with publication number CN217098918U proposes a membrane switch coating device, which adopts the design of a positioning component. The positioning component can fix the tensioning roller on the front side of the sliding block, and there is no need to remove the tensioning roller when adjusting the height of the tensioning roller, so that the height adjustment of the tensioning roller can be carried out relatively simply.

[0004] However, in the above technical solution, although the height adjustment of the tensioning roller can be carried out relatively easily, after the user's laminating operation is completed, it is necessary to take a new film and continue to pass it through the tensioning roller for straightening and stretching. When a large number of laminated switches need to be laminated, the efficiency of this laminating device will be relatively limited. Therefore, the utility model aims to provide a more efficient membrane switch laminating device. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example: See Figures 1 to 7 According to an embodiment of the utility model, a technical solution is provided: a membrane switch coating device, comprising an operating table 1, a switch body 2 and two hinged seats 3 relatively spaced apart and arranged on the operating table 1, a rotating roller 4 rotatably arranged between the two hinged seats 3, a film to be coated 5 is sleeved on the rotating roller 4, and a cutting frame 6 is also included, which is arranged on the operating table 1, and the switch body 2 is placed between the hinged seat 3 and the cutting frame 6; a first electric telescopic rod 7, which is arranged on the top of the cutting frame 6, the output end of the first electric telescopic rod 7 is arranged downward, and a cutting knife 9 is arranged on the output end of the first electric telescopic rod 7, and a second electric telescopic rod 8 is also arranged on the operating table 1, which is suitable for pressing the film to be coated 5 to the first end of the switch body 2; and an operating plate 10, a cutting hole 11 suitable for inserting the cutting knife 9 is penetrated at the second end of the operating plate 10, and the operating plate 10 is driven by a driving mechanism 12 to move the operating plate 10 along the length of the operating table 1.

[0030] With the membrane switch coating device of the above structure, when the user performs the coating operation, the user first pulls one end of the membrane to be coated 5 (the membrane to be coated 5 is a membrane of a membrane switch rolled up in multiple layers, such as a cylindrical toilet paper) so that it can be pressed onto the switch body 2 by the second electric telescopic rod 8. When the first end of the membrane to be coated 5 is pressed onto the switch body 2 by the second electric telescopic rod 8, the operating panel 10 is driven to move by the driving mechanism 12, and the first end of the operating panel 10 presses the membrane to be coated 5 under the cutting frame 6 (when the membrane to be coated 5 is pressed, the membrane to be coated 5 rotates to extend the length of the membrane to be coated 5, such as a cylindrical toilet paper being pulled). At this time, the cutting knife 9 is driven by the first electric telescopic rod 7 to press the membrane to be coated 5 under the cutting frame 6. After passing through the cutting hole 11, when the tension of the film to be coated 5 reaches a threshold value, it will be cut into two parts by the cutting knife 9. The cutting knife 9 will straighten the cut film to be coated 5 and press it against the bottom of the cutting frame 6 to facilitate the user to perform coating. After the user finishes coating, the cutting knife 9 is driven to reset by the first electric telescopic rod 7, and then the output end of the second electric telescopic rod 8 is reset to make the retracted output end of the second electric telescopic rod 8 separate from the film to be coated 5. Then, the driving mechanism 12 is used to move and reset the operating panel 10. When the operating panel 10 moves, the film to be coated 5 on the operating panel 10 will be moved to one side of the output end of the second electric telescopic rod 8, so that the user can perform the next coating operation, thereby improving the user's coating efficiency.

[0031] In this embodiment, the driving mechanism 12 includes two hinge blocks 13, two rollers 14, a motor 15 and two rotating shafts 16. The two hinge blocks 13 are arranged on the operating table 1 at a relative interval. The two rotating shafts 16 are rotatably arranged between the two hinge blocks 13 along the length direction of the hinge blocks 13. The two rollers 14 are respectively sleeved on the two rotating shafts 16. The spacing between the two rollers 14 is suitable for horizontally placing the operating panel 10, and one of the rotating shafts 16 is driven to rotate by the motor 15; when the user needs to drive the operating panel 10 to move along the length direction of the operating table 1, the motor 15 is used to drive the rotating shaft 16 to rotate, so as to drive the rollers 14 to rotate. When the two rollers 14 rotate, the operating panel 10 sandwiched between the two rollers 14 will be moved by friction, so that the operating panel 10 moves along the length direction of the operating table 1.

[0032] Alternatively, the driving mechanism 12 may also be configured as other suitable structures or forms, for example, directly connecting the operating panel 10 to an electric hydraulic cylinder, and opening and closing the hydraulic cylinder so that the output end of the hydraulic cylinder drives the operating panel 10 to move.

[0033] In this embodiment, a friction reducing wheel 17 is rotatably provided at the second end of the operating plate 10; when the operating plate 10 presses against the film 5 to be coated, the friction reducing wheel 17 reduces the friction of the operating plate 10 on the film 5 to be coated, so as to prevent the operating plate 10 from damaging the film 5 due to excessive friction.

[0034] In this embodiment, the operating panel 10 is provided with a limit groove 18 along its length direction, and the limit groove 18 is suitable for the movement of the roller 14; when the roller 14 rolls on the operating panel 10, the limit groove 18 will limit the roller 14 to roll outside the limit groove 18, so that the movement of the operating panel 10 is more stable.

[0035] In this embodiment, an extension groove 19 is provided on the operating table 1 along its length direction, and a wire rod 20 is installed in the extension groove 19. The two ends of the wire rod 20 are rotatably arranged on the operating table 1, and a moving block 21 is formed on the bottom of the cutting frame 6. The moving block 21 is threadedly connected with the wire rod 20; when it is necessary to perform coating operation on switch bodies 2 of different lengths, the moving block 21 and the cutting frame 6 are driven to move along the length direction of the operating table 1 by rotating the wire rod 20 to increase or decrease the distance between the cutting frame 6 and the hinge seat 3, so as to adapt to the lengths of different switch bodies 2.

[0036] In this embodiment, the first end of the screw rod 20 passes through the operating table 1, and an L-shaped handle 22 is provided at the first end of the screw rod 20; when the user rotates the screw rod 20, the handle 22 will provide the user with a rotation fulcrum to facilitate the user to rotate the screw rod 20.

[0037] Working principle: When the user performs the laminating operation, first pull one end of the film to be coated 5 (the film to be coated 5 is a film of a membrane switch rolled up in multiple layers, such as a cylindrical toilet paper) so that it can be pressed against the switch body 2 by the second electric telescopic rod 8. When the first end of the film to be coated 5 is pressed against the switch body 2 by the second electric telescopic rod 8, the motor 15 is used to drive the rotating shaft 16 to rotate, so as to drive the roller 14 to rotate. When the two rollers 14 rotate, the operating panel 10 sandwiched between the two rollers 14 will be moved by friction, so that the operating panel 10 moves along the length direction of the operating table 1, and then , the first end of the operating panel 10 will press the film to be coated 5 under the cutting frame 6 (when the film to be coated 5 is pressed, the film to be coated 5 will rotate to extend the length of the film to be coated 5, just like a cylindrical toilet paper being pulled). At this time, the first electric telescopic rod 7 drives the cutting knife 9 to press the film to be coated 5 through the cutting hole 11. When the tension of the film to be coated 5 reaches the threshold, it will be cut into two parts by the cutting knife 9. The cutting knife 9 will straighten the cut film to be coated 5 and press it against the bottom of the cutting frame 6 to facilitate the user to perform the coating. After the user finishes the coating, the first electric telescopic rod 7 drives the cutting knife 9 to reset, and then The output end of the second electric telescopic rod 8 is reset to make the output end of the second electric telescopic rod 8 detach from the film to be coated 5, and then, the motor 15 is used to drive the rotating shaft 16 to reverse, so that the roller 14 is turned over until the operation panel 10 is moved and reset. When the operation panel 10 moves, the film to be coated 5 on the operation panel 10 is moved to the output end of the second electric telescopic rod 8, so that the user can perform the next coating operation, thereby improving the coating efficiency of the user; when the operation panel 10 presses against the film to be coated 5, the friction-reducing wheel 17 reduces the friction of the operation panel 10 on the film to be coated 5, so as to prevent the operation panel 10 from being excessively rubbed. The coating 5 is greatly damaged; when the roller 14 rolls on the operating panel 10, the limit groove 18 will limit the roller 14 to the outside of the limit groove 18, so that the movement of the operating panel 10 is more stable; when it is necessary to coat the switch bodies 2 of different lengths, the moving block 21 and the cutting frame 6 are driven to move along the length direction of the operating table 1 by rotating the screw rod 20 to increase or decrease the spacing between the cutting frame 6 and the hinge seat 3, so as to adapt to the length of the switch bodies 2 of different lengths; when the user rotates the screw rod 20, the turning handle 22 will give the user a fulcrum for rotation, so that the user can rotate the screw rod 20 conveniently.
