Description

Technical Field

[0001] The utility model relates to the technical field of film pasting on the surface of plastic products, and more specifically, to a jig for pasting film on the surface of electrical plastic products. Background Art

[0002] Electrical plastic products refer to various plastic products used in electrical appliances. These products are widely used in the electronics and electrical appliance fields, primarily due to the excellent properties of plastics, such as insulation, heat resistance, corrosion resistance, lightness, and plasticity. After molding, some plastic products have high requirements for surface quality. To prevent scratches or stains on the surface of the plastic product, a protective film is often applied to the surface of the plastic product to prevent this. Existing surface film application jigs for electrical plastic products typically require workers to remove the film and manually flip it over before applying the film on the other side. This increases the worker's workload, complicates the operation, and reduces the efficiency of surface film application for electrical plastic products. Furthermore, some surface film application jigs for electrical plastic products can easily generate bubbles between the tempered film and the plastic product surface during use, affecting the aesthetics of the applied electrical plastic product and reducing the effectiveness of the application.

A first motor 12 is fixed on one side of the operating table 1, and the driving end of the first motor 12 extends into the lifting chamber 6 and is fixedly connected to the rotating frame 9.

[0029] In this embodiment, when it is necessary to fix the electrical plastic product, it is placed on the lifting platform 8 and placed between the two clamping plates 11 of the rotating frame 9, and the two third electric push rods 10 are started. The third electric push rods 10 drive the clamping plates 11 to move along the sliding connection with the rotating frame 9, so that the two clamping plates 11 cooperate to clamp and fix the electrical plastic product in the rotating frame 9, and the tempered film is placed on multiple suction cups 5 and fixed by the suction cups 5. The first electric push rod 3 is started, and the first electric push rod 3 drives the film plate 4 to move downward. The film plate 4 drives the tempered film downward through multiple suction cups 5, so that the tempered film is attached to the clamped and fixed electrical plastic product. After the film is attached, the first electric push rod 3 is started, so that the film plate 4 drives the suction cup 5 to move upward, and the suction cup 5 is separated from the tempered film. When it is necessary to apply film to the other side of the electrical plastic product, the second electric push rod 7 is started, and the second electric push rod 7 drives the lifting platform 8 to move downward, and the first motor 12 is started, and the first motor 12 drives the rotating frame 9 and the clamped electrical plastic product to rotate 180 degrees, so as to turn it over and then apply film to it.

[0030] See also Figure 1-Figure 5 , as an implementation method for driving out bubbles after film pasting: a movable frame 13 is movably provided above the operating table 1, and a pressing roller 14 is rotatably provided on the movable frame 13, and a support plate 15 is fixed on the operating table 1, and a movable groove 16 is provided on one side of the support plate 15, and a screw 17 is rotatably provided in the movable groove 16. A second motor 18 is fixed on one side of the support plate 15, and the driving end of the second motor 18 extends into the movable groove 16 and is fixedly connected with the screw 17, and the screw 17 is threadedly connected with a movable seat 19. A connecting arm 20 is fixed on one side of the movable seat 19 through the movable groove 16, and a fourth electric push rod 21 is provided on the connecting arm 20, and the driving end of the fourth electric push rod 21 is fixedly connected with a lifting plate 22 through the connecting arm 20, and a limiting rod 23 is movably provided on the lifting plate 22. The number of the limiting rods 23 is two, and the lower end of the limiting rod 23 passes through the lifting plate 22 and is fixedly connected to the movable frame 13, and a spring 24 is movably sleeved on the outer side of the limiting rod 23.

[0031] Specifically, the second motor 18 is started, and the second motor 18 drives the screw 17 to rotate. Since the screw 17 is threadedly connected to the movable seat 19, the movable seat 19 drives the connecting arm 20 to move, and the connecting arm 20 drives the fourth electric push rod 21, the lifting plate 22, the limit rod 23, the spring 24, the movable frame 13 and the pressing roller 14. When the pressing roller 14 moves to the electrical plastic product, the fourth electric push rod 21 is started, and the fourth electric push rod 21 drives the lifting plate 22 to move downward, and the lifting plate 22 drives the limit rod 23, the movable frame 13 and the pressing roller 14. 4 moves, so that the pressing roller 14 contacts the upper end of the tempered film. As the lifting plate 22 continues to move downward, the movable frame 13 moves upward relative to the lifting plate 22, the limiting rod 23 limits it, and the spring 24 is compressed. Under the push of the spring 24, the fourth electric push rod 21 is closed. Under the push of the spring 24, the movable frame 13 has a downward force, so that the pressing roller 14 presses the tempered film downward. As the movable base 19 continues to move, the pressing roller 14 rotates, thereby squeezing out the air between the tempered film and the electrical plastic product to reduce bubbles.

[0032] See also Figure 1-Figure 5 As an implementation method for preventing electrical plastic products from falling during rotation: support frames 25 are fixed on both sides of the rotating frame 9, a fifth electric push rod 26 is fixed on the support frame 25, a moving plate 27 is fixed on the driving end of the fifth electric push rod 26, a shift rod 28 is fixed on the moving plate 27, and the number of the shift rods 28 is four. The four shift rods 28 are respectively fixed at the upper and lower ends of the moving plate 27, and the lifting platform 8 is provided with grooves 29 that cooperate with the shift rods 28. The number of the grooves 29 is four.

[0033] Specifically, the two fifth electric push rods 26 are activated, causing the fifth electric push rods 26 to move the movable plate 27, which in turn drives the levers 28 to move, so that the four levers 28 are moved to the upper and lower ends of the electrical plastic product to block it. The grooves 29 cooperate with the movement of the levers 28 at the lower ends. When the rotating frame 9 rotates, the rotating frame 9 drives the support frame 25 to rotate, which in turn drives the movable plate 27 and levers 28 to rotate, thereby blocking the rotating electrical plastic product and preventing it from falling. After the film is applied to the electrical plastic product, the levers 28 can also be moved to the upper and lower ends of the electrical plastic product. The levers 28 can also limit the tempered film, thereby facilitating the separation of the tempered film from the suction cup 5.

[0034] In summary, when the overall equipment is in use:

[0035] When it is necessary to double-sidedly film the electrical plastic product, place it on the lifting platform 8 and place it between the two clamping plates 11 of the rotating frame 9, start the two third electric push rods 10, and the third electric push rods 10 drive the clamping plates 11 to move along the sliding connection with the rotating frame 9, so that the two clamping plates 11 cooperate to clamp and fix the electrical plastic product in the rotating frame 9, place the tempered film on multiple suction cups 5, and fix it by the suction cups 5, start the first electric push rod 3, and the first electric push rod 3 drives the film-sticking plate 4 to move downward, and the film-sticking plate 4 drives the tempered film downward through the multiple suction cups 5, so that the tempered film is attached to the clamped and fixed electrical plastic product. After the film is pasted, start the first electric push rod 3, so that the film-sticking plate 4 drives the suction cup 5 to move upward, and the suction cup 5 is separated from the tempered film. When it is necessary to apply film to the other side of the electrical plastic product, the second electric push rod 7 is started, and the second electric push rod 7 drives the lifting platform 8 to move downward, and the first motor 12 is started, and the first motor 12 drives the rotating frame 9 and the clamped electrical plastic product to rotate 180 degrees, so as to turn it over and then apply film to it.

[0036] When the electrical plastic product is rotated to prevent it from falling, the two fifth electric push rods 26 are activated, so that the fifth electric push rods 26 drive the movable plate 27 to move, and the movable plate 27 drives the lever 28 to move, so that the four levers 28 move to the upper and lower ends of the electrical plastic product to block it. The groove 29 cooperates with the lever 28 at the lower end to move. When the rotating frame 9 rotates, the rotating frame 9 drives the support frame 25 to rotate, and the support frame 25 drives the movable plate 27 and the lever 28 to rotate, thereby blocking the rotating electrical plastic product and preventing it from falling. After the film is applied to the electrical plastic product, the lever 28 can also be moved to the upper and lower ends of the electrical plastic product. The lever 28 can also limit the tempered film, thereby facilitating the separation of the tempered film from the suction cup 5.

[0037] When the bubbles between the tempered film and the electrical plastic product are driven out, the second motor 18 is started, and the second motor 18 drives the screw 17 to rotate. Since the screw 17 is threadedly connected to the movable seat 19, the movable seat 19 drives the connecting arm 20 to move, and the connecting arm 20 drives the fourth electric push rod 21, the lifting plate 22, the limit rod 23, the spring 24, the movable frame 13 and the pressing roller 14. When the pressing roller 14 moves to the electrical plastic product, the fourth electric push rod 21 is started, and the fourth electric push rod 21 drives the lifting plate 22 to move downward, and the lifting plate 22 drives the limit rod 23 , the movable frame 13 and the pressing roller 14 move, so that the pressing roller 14 contacts the upper end of the tempered film. As the lifting plate 22 continues to move downward, the movable frame 13 moves upward relative to the lifting plate 22, the limit rod 23 limits it, and the spring 24 is compressed. Under the push of the spring 24, the fourth electric push rod 21 is closed. Under the push of the spring 24, the movable frame 13 has a downward force, so that the pressing roller 14 presses the tempered film downward. As the movable seat 19 continues to move, the pressing roller 14 rotates, thereby squeezing out the air between the tempered film and the electrical plastic product to reduce bubbles.

[0038] The entire device is controlled by a controller. Since the devices matched with the controller are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.
