The automatic film tearing machine can save financial and human resources, reduce personnel errors, reduce personnel workload and reduce product rejection rate. The vacuum debonding and automatic film tearing machine of the present invention and its use method are described below with reference to the accompanying drawings.

[0043] See Figure 1 , shows the structural diagram of the casing of the vacuum degumming and automatic film tearing machine of the present invention. Figure 1 , the structure of the vacuum degumming and automatic film tearing machine of the present invention is described.

[0044] like Figure 1 As shown, the vacuum debonding and automatic film tearing machine of the present invention is used to tear off the film attached to the product. The vacuum debonding and automatic film tearing machine includes a housing 21, a supporting platform 22, a light board 23, a position adjustment mechanism 24, a rotating roller 25 and a driving member; wherein the interior of the housing 21 is formed with an installation space 211; the supporting platform 22 is arranged in the installation space 211 of the housing 21, and the supporting platform 22 is installed on the housing 21, combined with Figure 2As shown, the carrier 22 is provided with a plurality of vacuum adsorption holes 224 for adsorbing the product; the lamp board 23 is provided in the installation space 211 of the housing 21, and the lamp board 23 is located above the carrier 22. The lamp board 23 is installed on the housing 21, and a plurality of purple lamps 231 are provided on the lower surface of the lamp board 23 for irradiating the film to be torn off on the product.

The mechanism 24 is installed on the casing 21, and the position adjustment mechanism 24 can be moved and adjusted in the vertical and horizontal directions; the rotating roller 25 is rotatably arranged on the position adjustment mechanism 24, and a plurality of suction cups 251 are provided on the periphery of the rotating roller 25. The movement and adjustment of the position adjustment mechanism 24 can move the rotating roller 25 so that the suction cups 251 on the rotating roller 25 can absorb the film to be torn off on the product; the driving member is provided on the position adjustment mechanism 24 and is driven and connected to the rotating roller 25. The driving member can drive the rotating roller 25 to rotate, so that the film on the product can be torn off by the rotation and movement of the rotating roller 25.

[0045] Initially, the rotating roller 25 is located outside the carrier 22 to avoid blocking the ultraviolet light from the ultraviolet lamp 231. The product adsorbed on the carrier 22 is irradiated by the ultraviolet light from the ultraviolet lamp 231, which removes the stickiness of the film, causing the film to loosen and bulge, and form wrinkles. The position adjustment mechanism 24 then moves the rotating roller 25 to one side of the carrier 22, and then moves downward to press the rotating roller 25 against the product on the carrier 22, so that the suction cup on the rotating roller 25 absorbs the loose and bulging film. The position adjustment mechanism 24 then moves the rotating roller 25 upward to a certain height to pull up the film. The driving member then drives the rotating roller 25 to rotate, and at the same time, the position adjustment mechanism 24 moves the rotating roller 25 toward the other side of the carrier 22, causing the rotating roller 25 to roll away the film on the product, achieving automatic film tearing.

[0046] In a specific embodiment of the present invention, the position adjustment mechanism 24 of the present invention includes a vertical adjustment member installed on the housing 21 and a horizontal adjustment component connected to the bottom of the vertical adjustment member; the vertical adjustment member can be raised and lowered in the vertical direction, and then raised and lowered together with the horizontal adjustment component; the horizontal adjustment component can be moved and adjusted in the horizontal direction; the rotating roller 25 is rotatably installed on the horizontal adjustment component, and the driving member is also installed on the horizontal adjustment component, so that the horizontal adjustment component can be moved and adjusted together with the rotating roller and the driving member.

[0047] Preferably, there are multiple vertical adjustment members, which are provided on both sides of the top of the housing 21, and the vertical adjustment members are located on both sides of the supporting platform 22. The vertical adjustment member is preferably a cylinder, which is vertically arranged. The cylinder rod of the cylinder can be extended and retracted up and down, thereby realizing the vertical lifting and lowering adjustment of the lateral adjustment component.

[0048] Furthermore, the lateral adjustment assembly includes lateral guide rails and lateral rodless cylinders disposed on both sides of the support platform 22; the lateral guide rails and lateral rodless cylinders are both fixedly connected to the bottom of the vertical adjustment member; the mounting seat of the lateral rodless cylinder is slidably mounted on the lateral guide rails, and the lateral rodless cylinder can drive the mounting seat to move and adjust along the lateral guide rails; the rotating roller 25 is rotatably mounted on the mounting seats of the two lateral rodless cylinders; and the driving member is mounted on the mounting seat of one of the lateral rodless cylinders. The driving member is preferably a motor, the motor shaft of which is connected to the mounting shaft of the rotating roller 25, thereby driving the rotating roller 25 to rotate.

[0049] In a specific embodiment of the present invention, Figure 1 and Figure 3 As shown, the ultraviolet lamps 231 are arrayed on the lamp board 23 , and the setting range of the ultraviolet lamps 231 is larger than the size of the product adsorbed on the supporting platform 22 , which can ensure that the film on the product is irradiated by the ultraviolet light.

[0050] Preferably, the size of the light panel 23 is consistent with the size of the supporting platform 22 .

[0051] Combine Figure 5 As shown, the purple light lamp 231 includes a purple light bulb, a memory and a magnetron connected to the purple light bulb. A control circuit is provided on the lamp board 23, which is connected to the memory and magnetron of each purple light lamp 231 and is used to control the turning on and off of the purple light bulb.

[0052] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the supporting platform 22 includes a mounting plate 221 fixedly connected to the housing 21 and a plurality of strip plates 222 connected to the mounting plate 221; both the strip plates 222 and the mounting plate 221 are provided with through holes, and an air suction pipe 223 is installed at the through hole, one end of the air suction pipe 223 is located on the upper surface of the strip plate 222 and forms a vacuum adsorption hole 224, and the other end extends out of the housing 21 and forms a vacuum system connection end.

[0053] Combine Figure 6As shown, the vacuum system includes a vacuum generator, a pneumatic valve connected to the vacuum generator, a start button connected to the pneumatic valve, and a triple air fitting connected to the pneumatic valve. The triple air fitting is connected to an external compressed air supply and can be connected to an air compressor to provide compressed air. The triple fitting can also be connected to a compressed air pipeline to provide compressed air. The start button can control the opening and closing of the pneumatic valve. The vacuum generator is connected to the vacuum system connection end of the suction pipe 223 on the carrier 22, providing suction force at the vacuum suction hole 224 to absorb the product.

[0054] In a specific embodiment of the present invention, Figure 1 and Figure 4 As shown, the suction cups 251 are provided in multiple rows on the outer circumference of the rotating roller 25 .

[0055] Preferably, the rotating roller 25 is provided with a plurality of threaded holes, and the suction cup 251 is provided with screws and is screwed to the threaded holes via the screws.

[0056] In one embodiment of the present invention, a vacuum gauge is mounted on the rotating roller 25, preferably between the two suction cups. The gauge measures the vacuum level on the surface of the rotating roller 25. When a film is wrapped around the surface of the rotating roller 25, the vacuum gauge measures a higher value than when the film is not wrapped around the surface. This allows a reference value to be set to determine whether the film is wrapped around the rotating roller 25. This allows the determination of whether the suction cups on the rotating roller 25 are holding the film. If not, the rotating roller 25 can be re-applied to ensure that the film is properly held and removed.

[0057] Preferably, the vacuum gauge is a digital vacuum gauge.

[0058] Furthermore, it also includes a controller connected to the vacuum meter and an alarm connected to the controller. The controller can obtain the vacuum value measured by the vacuum meter. When the rotating roller 25 rolls the film, the controller determines whether the vacuum value obtained by the vacuum meter is greater than or equal to the reference value. If not, it indicates that the rotating roller has not wrapped the film. At this time, the controller controls the alarm to sound an alarm. At the same time, the controller can also control the rotating roller to re-absorb the film.

[0059] The present invention also provides a method for using the vacuum glue removal automatic film tearing machine, which is described below.

[0060] The method of using the present invention comprises the following steps:

[0061] like Figure 1 As shown, provide a product to be torn off, place the provided product on the carrier 22 and use the vacuum adsorption holes to absorb the product;

[0062] Turn on the ultraviolet light lamp 231 and use the ultraviolet light emitted by the ultraviolet light lamp 231 to irradiate the product to remove the stickiness of the film on the product;

[0063] Move the rotating roller 25 by the position adjustment mechanism 24 so that the rotating roller 25 is pressed onto the product; and let the suction cup 251 on the rotating roller 25 suck the film on the product, and then let the rotating roller 25 be lifted up;

[0064] The driving member is started to drive the rotating roller 25 to rotate, and at the same time, the position adjustment mechanism 24 is used to move the rotating roller 25 toward the other end of the product, so that the rotating roller 25 tears off the film on the product through rotation and movement.

[0065] Furthermore, in order to ensure that the suction cup 251 on the rotating roller 25 sucks the film on the product, the rotating roller 25 can be pressed onto the product, and then the driving member is started to drive the rotating roller 25 to rotate one circle. At the same time, the position adjustment mechanism 24 is used to move forward a distance, which is preferably equal to the circumference of the rotating roller 25. In this way, the film on the product can be wrapped around the rotating roller 25, and then the rotating roller 25 can be lifted up.

[0066] Furthermore, a vacuum gauge is provided on the rotating roller 25, and the vacuum gauge can be used to detect the vacuum value on the surface of the rotating roller 25. When the film is wound on the rotating roller 25, the vacuum value detected by the vacuum gauge is greater than the vacuum value when the film is not wrapped around the surface of the rotating roller 25. In this way, a reference value can be set in advance. When the vacuum value detected by the vacuum gauge is greater than or equal to the reference value, it indicates that a film is wound on the rotating roller 25, that is, the suction cup has sucked the film. At this time, the position adjustment mechanism 24 can be controlled to move the rotating roller 25 upward. When the vacuum value detected by the vacuum gauge is less than the reference value, the rotating roller 25 is allowed to repeat the action of adsorbing the film on the product until the suction cup on the rotating roller 25 has sucked the film on the product.

[0067] Preferably, the vacuum gauge is installed between the two suction cups.

[0068] A controller is provided on the vacuum degumming and automatic film tearing machine, which is connected to the vacuum meter, position adjustment mechanism, ultraviolet lamp and driving component. It can control the position adjustment mechanism to adjust the position, control the switch of the ultraviolet lamp, and control the opening and closing of the driving component, thereby realizing automatic tearing of the film on the product.

[0069] Preferably, the product is placed on a product frame, which is then fixed to a support platform 22 by suction. The support platform is provided with multiple suction holes. The positioning of the suction holes and the size of the support platform 22 allow the support platform to adapt to product frames of various sizes. This eliminates the need for fixture replacement or mechanical adjustments for different product frames, reducing buy-off time.

[0070] The film to be torn off on the product of the present invention is a high-temperature film.

[0071] The present invention has been described in detail above with reference to the embodiments of the accompanying drawings. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
