DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "fixed", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0033] In the present invention, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may include the first feature and the second feature being in direct contact, or may include the first feature and the second feature being in contact not directly but through another feature between them. Moreover, a first feature being “above”, “below”, and “above” a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature includes the first feature being below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present application.

[0035] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0036] like Figure 1As shown, the coating device of this embodiment mainly includes: a feeding mechanism, a supporting mechanism 2, a pulling mechanism 3, a cutting mechanism 4 and a film taking mechanism (not shown). The feeding mechanism is used to feed the incoming roll of adhesive film. The incoming adhesive film includes an adhesive surface and a non-adhesive surface arranged relatively. The adhesive surface of the outer circle of the adhesive film of the material roll 100 is adhered to the non-adhesive surface of the inner circle of the adhesive film. In other words, the adhesive film of this embodiment does not contain release paper when it is incoming. The inner and outer circles of the adhesive film do not need to be isolated by release paper, but are directly adhered to each other. The supporting mechanism 2 is arranged on the discharge side of the feeding mechanism, including a first supporting platform 21 for supporting the adhesive film. When the first supporting platform 21 supports the adhesive film, it contacts the adhesive surface of the adhesive film. The pulling mechanism 3 is used to pull the adhesive film at the feeding mechanism onto the first supporting platform 21, so as to realize the automatic feeding of the adhesive film onto the first supporting platform 21. The cutting mechanism 4 is arranged between the feeding mechanism and the carrying mechanism 2. When the film is pulled to the first carrying platform 21 by the pulling mechanism 3 and attached to the first carrying platform 21, the cutting mechanism 4 cuts the film on the first carrying platform 21 from the material roll 100 to obtain a single film to be covered on the product. The film taking mechanism is used to transplant the single film separated from the material roll 100 on the first carrying platform 21 to the product to be coated. Specifically, the film taking mechanism may include a manipulator and a vacuum suction module arranged at the end of the manipulator. The vacuum suction module can be realized by a suction cup (or a plate with air holes) connected to the vacuum system. When the film taking mechanism sucks the film on the first carrying platform 21, it contacts the non-adhesive surface of the film. Of course, the coating device of this embodiment also includes an electronic control system for controlling the above-mentioned multiple mechanisms to achieve automation.

[0037] Through the above structure, the laminating device of this embodiment adopts the cutting mechanism 4 to cut the film without release paper pulled by the pulling mechanism 3 onto the supporting mechanism 2 online, and then absorbs the single film on the supporting mechanism 2 through the film taking mechanism to laminate the product to be laminated. Compared with the traditional method of tearing off the film from the release paper, the present device eliminates the complicated process of tearing off the film, avoids the problem of film deformation during the tearing process, and greatly improves the product lamination yield; at the same time, when the present device is used for lamination, the incoming film can save the release paper, simplifying the film production process and saving the film procurement cost.

[0038] Combination Figure 1 and Figure 2 As shown, the feeding mechanism of this embodiment includes a first bracket 11, a feeding roller 12, a second bracket 13 and a pressing roller 14. The feeding roller 12 is rotatably connected to the first bracket 11, and is used to feed the material roll 100 mounted thereon; the pressing roller 14 is rotatably connected to the second bracket 13 and is located above the adhesive film, and the pressing roller 14 presses the adhesive film from the non-adhesive surface thereof, so that the adhesive film is in a tensioned state.

[0039] Preferably, if Figure 2As shown, the feeding mechanism of this embodiment further includes a first power source 15. The second bracket 13 is connected to the output shaft of the first power source 15, and the first power source 15 is used to drive the second bracket 13 to rise and fall, thereby driving the pressing roller 14 to rise and fall, so as to facilitate the installation and feeding of a new material roll 100. Specifically, when a new material roll 100 is installed on the unwinding roller 12 and is about to be fed, the pressing roller 14 can be driven to rise by the first power source 15, and then the staff manually pulls the film at the starting position of the new material roll 100 onto the first bearing platform 21. In this process, since the position of the pressing roller 14 rises, a larger space is provided for the staff to operate, and then the first power source 15 drives the pressing roller 14 to descend to press the film.

[0040] like Figure 3 As shown, the material pulling mechanism 3 of this embodiment includes a third bracket 31, a fourth bracket 32, a first synchronous belt transmission module 33, a second synchronous belt transmission module 34, a first clamping claw cylinder 35 and a second clamping claw cylinder 36. Among them, the first synchronous belt transmission module 33 is installed on the third bracket 31, and the second synchronous belt transmission module 34 is installed on the fourth bracket 32; the first clamping claw cylinder 35 is installed on the first synchronous belt transmission module 33, and the second clamping claw cylinder 36 is installed on the second synchronous belt transmission module 34. The first synchronous belt transmission module 33 and the second synchronous belt transmission module 34 are driven by the same motor 334 to ensure the synchronization of the two movements. When the motor 334 is driven, the first synchronous belt and the second synchronous belt rotate, respectively driving the first clamping cylinder 35 and the second clamping cylinder 36 to move back and forth between the feeding mechanism and the first supporting platform 21, the first clamping cylinder 35 drives the two first clamping jaws 351 to clamp one side of the film, and the second clamping cylinder 36 drives the two second clamping jaws 361 to clamp the other side of the film, and then pulls the film onto the first supporting platform 21.

[0041] Preferably, continue to refer to Figure 3 As shown, the material pulling mechanism 3 of this embodiment also includes a first mounting frame 37, a second power source 38 and a pressing plate 39. The first mounting frame 37 is connected to the first clamping jaw cylinder 35 and / or the second clamping jaw cylinder 36 and moves therewith. The second power source 38 is mounted on the first mounting frame 37, and the output shaft of the second power source 38 is connected to the pressing plate 39, and the second power source 38 is used to drive the pressing plate 39 to rise and fall. When the material pulling mechanism 3 pulls the adhesive film to a preset position on the first bearing platform 21, the second power source 38 drives the pressing plate 39 to descend to press the adhesive film from the non-adhesive surface of the adhesive film, ensuring that the adhesive film is adhered to the first bearing platform 21, and avoiding the adhesive film from leaving the surface of the first bearing platform 21 and wrinkling when the first clamping jaw 351 and the second clamping jaw 361 are loosened.

[0042] like Figure 4As shown, the bearing mechanism 2 of this embodiment also includes a third power source 22. The first bearing platform 21 is installed on the output shaft of the third power source 22, and the third power source 22 is used to drive the first bearing platform 21 to rise and fall. When the pulling mechanism 3 goes back and forth between the feeding mechanism and the bearing mechanism 2 to pull the material and place the film, the third power source 22 can drive the first bearing platform 21 to descend to avoid the clamping cylinder and the clamping claw of the pulling mechanism 3. When the pulling mechanism 3 pulls the film to the first bearing platform 21, the third power source 22 drives the first bearing platform 21 to rise to receive the film. Further, two first grooves 211 are provided at one end of the first bearing platform 21 away from the feeding mechanism, one of which is used to make way for the first clamping claw 351, and the other is used to make way for the second clamping claw 361. In this way, when the pulling mechanism 3 places the film on the first bearing platform 21, it will not interfere with the first bearing platform 21.

[0043] Continue to refer to Figure 4 As shown, the first carrier 21 of this embodiment includes a main body 212 and a plurality of ceramic sheets 213 arranged on the main body 212, wherein the main body 212 can be made of bakelite. The plurality of ceramic sheets 213 are used to carry the adhesive film and contact the adhesive surface of the adhesive film. The ceramic sheets 213 contact the adhesive surface of the adhesive film to reduce the bonding strength between the two and reduce the difficulty of the film taking mechanism to absorb the adhesive film from the first carrier 21. The plurality of ceramic sheets 213 are arranged at intervals, that is, two adjacent ceramic sheets 213 do not contact each other and have a certain distance, so as to reduce the overall contact area between the adhesive film and the ceramic sheets 213, which can further reduce the bonding strength. Furthermore, a plurality of air channels 214 are provided on the main body 212 and the ceramic sheet 213. The air channels 214 penetrate the upper end surface and the side surface of the main body 212, and also penetrate the upper and lower surfaces of the ceramic sheet 213. These air channels 214 are used to connect with the blowing system. When the film taking mechanism absorbs the film on the first supporting platform 21, the blowing system simultaneously blows air to the film through the air channels 214 to apply an upward force to the film, so as to facilitate the film to be separated from the first supporting platform 21.

[0044] Combination Figure 5 and Figure 6As shown, the cutting mechanism 4 of this embodiment includes a fifth bracket 41 , a second bearing platform 42 , a third bearing platform 43 , a fourth power source 44 , a second mounting frame 45 , a two-axis driving module 46 and a cutter 47 . Among them, the second supporting platform 42 is connected to the fifth bracket 41 and is located below the pressure roller 14 of the feeding mechanism; the fourth power source 44 is installed on the fifth bracket 41, and the third supporting platform 43 is connected to the output shaft of the fourth power source 44, and the fourth power source 44 is used to drive the third supporting platform 43 to rise and fall; the third supporting platform 43 is located at one end of the second supporting platform 42 facing the first supporting platform 21. When the film is to be cut, the fourth power source 44 drives the third supporting platform 43 to rise to jointly support the film with the second supporting platform 42 (or, to jointly support the film); the two-axis drive module 46 is connected to the second mounting frame 45, and is used to drive the tool 47 to move in the vertical and horizontal directions to cut the film, that is, the two-axis drive module 46 drives the tool 47 to rise and fall, and move in a direction perpendicular to the film strip.

[0045] like Figure 2 As shown, the cutting mechanism 4 of this embodiment also includes a fifth power source. The second mounting frame 45 is connected to the output shaft of the fifth power source, and the fifth power source is used to drive the second mounting frame 45 to move in the direction toward and away from the first bearing platform 21, thereby driving the two-axis driving module 46 and the cutter 47 to move. With this solution, when the material pulling mechanism 3 moves toward the second bearing platform 42 to pull the film, the fifth power source simultaneously drives the second mounting frame 45 to move in the direction away from the first bearing platform 21 (towards the material roll 100) to avoid the material taking part of the material pulling mechanism 3 to avoid the two from colliding; when the material pulling mechanism 3 moves toward the first bearing platform 21 to place the film, the fifth power source simultaneously drives the second mounting frame 45 to move toward the first bearing platform 21 (away from the material roll 100) to wait for the next cutting.

[0046] Combination Figure 5 and Figure 7 As shown, the second carrier platform 42 of this embodiment is provided with a second groove 421 at one end thereof facing the third carrier platform 43. The third carrier platform 43 includes a first portion 431 and a second portion 432 connected to each other, the second portion 432 is located at one end of the first portion 431 away from the second carrier platform 42, and the second portion 432 is provided with a third groove 4321 for making way for the tool 47. When cutting is required, the fourth power source 44 drives the third carrier platform 43 to rise until its upper surface is aligned with the upper surface of the second carrier platform 42, so that the two can support the film together, at this time, the first portion 431 of the third carrier platform 43 is located in the second groove 421 of the second carrier platform 42; when cutting is completed, the fourth power source 44 drives the third carrier platform 43 to descend to avoid the material taking component of the pulling mechanism 3 (such as the lifting and lowering action of the first carrier platform 21 in the figure).

[0047] Preferably, continue to refer to Figure 5 and Figure 7 As shown, when the third carrier 43 is raised to support the adhesive film, the second portion 432 of the third carrier 43 is spaced from the second carrier 42 to form a fourth groove 423, or in other words, the two are not connected and there is a certain distance between them, which is substantially the same as the size of the first clamping jaw 351 and the second clamping jaw 361. This solution can reduce the bonding area between the adhesive film and the third carrier 43, and reduce the difficulty of separating the two.

[0048] In this embodiment, the first power source 15, the second power source 38, the third power source 22, the fourth power source 44 and the fifth power source may all be cylinders.

[0049] In summary, the working process of the laminating device of this embodiment is as follows: the material roll 100 is installed on the unwinding roller 12, and the personnel manually pulls the film at the starting position of the material roll 100 to the first supporting platform 21, the pressing roller 14 descends to press the material belt, the third supporting platform 43 rises, and the two-axis driving module 46 drives the tool 47 to cut the film and take away the first film, and the subsequent actions can be fully automated; the material taking component of the pulling mechanism 3 moves toward the second supporting platform 42, and at the same time, the first supporting platform 21 and the third supporting platform 43 descend, and the second mounting frame 45 retreats in the direction of the material roll 100 to avoid the pulling mechanism 3; when the pulling mechanism 3 pulls the film to the preset position, the first supporting platform 21 and the third supporting platform 43 rise to support the film, and the second mounting frame 45 drives the tool 47 to move in the direction of the third supporting platform 43 to wait for the next cutting; after the film on the first supporting platform 21 is cut, the film taking mechanism absorbs the film and moves it to the product to be coated.

The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.
