[0002] To meet the needs of applying a specified length of transparent tape, double-sided tape, or other adhesive materials with complex material properties to product surfaces, a variety of automated, high-efficiency taping machines are available on the market. For example, Chinese invention patent publication number CN104773595B provides an automatic taping machine, comprising a frame, a material hopper, a material conveyor belt line, a fixed-length taping and cutting device, and an electrical control box.

[0029] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0030] The key concept of the present invention is that through the design of the straight cutting knife mechanism and the circular cutting knife mechanism, in conjunction with the adhesive paper conveying device and the release paper receiving device, it is possible to freely choose whether the release paper remains after the adhesive paper is cut, thereby meeting the two needs of directly laminating the glass with other objects after laminating or placing it after laminating.

[0031] like Figures 1 to 2 As shown, the automatic glue laminating machine of the present invention comprises a frame 11, a cutting device is provided on the frame 11, and a glue paper conveying device and a release paper receiving device 4 are respectively provided on both sides of the cutting device;

[0032] The cutting device includes a straight cutting blade mechanism 21 and a circular cutting blade mechanism 22 that are arranged opposite to each other. The cutting device is connected to the frame 11 through a first slide rail 5 .

[0033] As can be seen from the above description, the adhesive tape is fed out by the adhesive tape conveying device and sent to the cutting device, and the straight cutter mechanism 21 or the circular cutter mechanism 22 can be freely selected for cutting; when the straight cutter mechanism 21 is selected, the straight cutter mechanism 21 moves to the cutting position through the first slide rail 5, and only cuts the adhesive layer of the adhesive tape. The release paper is removed by the release paper receiving device 4. The glass after attachment has no release paper and can directly proceed to the next step of bonding; when the circular cutter mechanism 22 is selected, the circular cutter mechanism 22 moves to the cutting position through the first slide rail 5, and cuts the adhesive layer and release paper of the adhesive tape at the same time. The glass after attachment has release paper and can be stacked, saving space and preventing the adhesive layer from failing.

[0034] Furthermore, the adhesive tape conveying device is composed of a spoke wheel 31, a first tensioning wheel 32 and an adhesive tape guiding device 33. The first tensioning wheel 32 and the adhesive tape guiding device 33 enable the adhesive tape to be horizontally conveyed to the cutting device.

[0035] As can be seen from the above description, the spoke wheel 31 and the first tensioning wheel 32 cooperate with each other to ensure that the adhesive tape is output stably and smoothly; the first tensioning wheel 32 and the adhesive tape guide device 33 transport the adhesive tape horizontally to the cutting device, so that the adhesive tape can still be output stably after cutting the release paper.

[0036] Furthermore, the adhesive tape guiding device 33 is located between the straight cutter mechanism 21 and the circular cutter mechanism 22 .

[0037] As can be seen from the above description, the straight cutter mechanism 21 or the circular cutter mechanism 22 can be freely selected for use.

[0038] Furthermore, the release paper receiving device 4 includes a second tensioning wheel 41, a third tensioning wheel 42, a fourth tensioning wheel 43 and a receiving wheel 44 arranged in sequence from top to bottom, and the second tensioning wheel 41, the third tensioning wheel 42, the fourth tensioning wheel 43 and the receiving wheel 44 are arranged on the frame 11.

[0039] As can be seen from the above description, the release paper is hard and has a slippery surface, and is easy to fall off when winding. Multiple tensioning wheels are required to complete the winding of the release paper.

[0040] Furthermore, the receiving wheel 44 is in transmission connection with the driving machine 6 .

[0041] Furthermore, the straight cutter mechanism 21 includes a straight cutter 211 support and a straight cutter 211 disposed on the straight cutter 211 support;

[0042] The angle between the straight cutter 211 and the straight cutter 211 support is adjustable;

[0043] The straight cutting knife 211 bracket includes a first limiting slider 212 , and the first limiting slider 212 can reciprocate along the axial direction of the first slide rail 5 .

[0044] As can be seen from the above description, the straight cutter 211 uses a guillotine-like cutting motion. The angle between the straight cutter 211 and its support is adjustable, accommodating the cutting of adhesive layers of varying thicknesses. When the straight cutter mechanism 21 is selected for cutting, the first limiting slider 212 guides the straight cutter mechanism 21 along the first slide rail 5 to the top of the adhesive tape. The angle between the straight cutter 211 and its support gradually decreases until the adhesive layer is completely cut.

[0045] Furthermore, the circular cutter mechanism 22 includes a circular cutter 221 bracket and a circular cutter 221 disposed on the circular cutter 221 bracket;

[0046] The circular cutter 221 can reciprocate in the vertical direction;

[0047] The bracket of the circular cutter 221 includes a second limiting slider 222 , and the second limiting slider 222 can reciprocate along the axial direction of the first slide rail 5 .

[0048] Furthermore, the bracket of the circular cutter 221 includes a first bracket and a second bracket, the first bracket is connected to the circular cutter 221, the second bracket is connected to the second limiting slider 222, and the first bracket and the second bracket are slidably connected.

[0049] From the above description, it can be seen that when the circular cutter mechanism 22 is selected for cutting, the circular cutter mechanism 22 moves along the first slide rail 5 to the top of the adhesive paper under the action of the second limiting slider, and the first bracket slides downward along the second bracket. The circular cutter 221 on the first bracket also moves downward to complete the cutting of the adhesive layer and the release paper.

[0050] like Figures 3 and 4 The automatic gluing device shown includes three groups of gluing devices. Guardrails 7 are provided between each group of gluing devices. Each group of gluing devices includes two automatic gluing machines 1.

[0051] From the above description, it can be seen that the guardrail 7 provides safety protection, and the three groups of gluing devices can rotate, one group rotates to the work station to glue, and the other two groups wait for glue replenishment. There is no need to stop the machine to replenish the adhesive tape, which greatly increases the efficiency of gluing.

[0052] The automatic glue laminating machine of the present invention is applied to glass glue laminating.

[0053] Please refer to Figures 1 to 2 As shown, the first embodiment of the present invention is:

[0054] An automatic glue sticking device includes three groups of glue sticking devices, each group of glue sticking devices is provided with a guardrail 7, and each group of glue sticking devices includes two automatic glue sticking machines 1. The angle between the axes of each group of glue sticking devices along the horizontal direction is 120 degrees.

[0055] The automatic gluing machine 1 comprises a frame 11, on which a cutting device is provided, and on both sides of the cutting device are provided a glue paper conveying device and a release paper receiving device 4 respectively;

[0056] The cutting device includes a straight cutting knife mechanism 21 and a circular cutting knife mechanism 22 arranged opposite to each other, and the cutting device is connected to the frame 11 through the first slide rail 5;

[0057] The straight cutter mechanism 21 includes a straight cutter 211 bracket and a straight cutter 211 disposed on the straight cutter 211 bracket, and the angle between the straight cutter 211 and the straight cutter 211 is adjustable; the straight cutter 211 bracket is also provided with a first limiting slider 212, which can reciprocate along the axial direction of the first slide rail 5;

[0058] The circular cutter mechanism 22 includes a circular cutter 221 bracket and a circular cutter 221 and a second limiting slider 222 arranged on the circular cutter 221 bracket. The second limiting slider 222 can reciprocate axially along the first slide rail 5. The circular cutter 221 bracket includes a first bracket and a second bracket. The first bracket is connected to the circular cutter 221, and the second bracket is connected to the second limiting slider 222. The first bracket and the second bracket are slidably connected, and the first bracket can reciprocate in the vertical direction.

[0059] The adhesive tape conveying device consists of a spoke wheel 31, a first tensioning wheel 32 and an adhesive tape guide device 33, which can horizontally convey the adhesive tape to the cutting device; the adhesive tape guide device 33 is located between the straight cutter mechanism 21 and the circular cutter mechanism 22.

[0060] The release paper receiving device 4 includes a second tensioning wheel 41 , a third tensioning wheel 42 , a fourth tensioning wheel 43 and a receiving wheel 44 which are sequentially arranged on the frame 11 from top to bottom. The receiving wheel 44 is in transmission connection with the driving machine 6 .

[0061] The working principle of the present invention is: Figure 3-4 The three groups of gluing devices on the automatic gluing device are rotatable, one of which rotates to the work station to glue, and the other two groups wait for glue replenishment. There is no need to stop the machine to replenish the adhesive paper, which greatly increases the efficiency of gluing. When gluing, the adhesive paper on each automatic gluing machine 1 is sent to the cutting device through the first tensioning wheel 32 and the adhesive paper guide device 33, and the straight cutter mechanism 21 or the circular cutter mechanism 22 can be freely selected for cutting. When the straight cutter mechanism 21 is selected, the straight cutter 211 adopts a guillotine cutting method, and the angle between the straight cutter 211 and the straight cutter 211 bracket is adjustable, which can adapt to the cutting of adhesive layers of different thicknesses. When the straight cutter mechanism 21 is selected for cutting, the straight cutter mechanism 21 moves above the adhesive paper along the first slide rail 5 under the action of the first limiting slider 212, and the angle between the straight cutter 211 and the straight cutter 211 bracket gradually becomes smaller until the cutting of the adhesive layer is completed. The release paper is collected in turn by the second tensioning wheel 41, the third tensioning wheel 42, the fourth tensioning wheel 43 and the collecting wheel 44. The glass after attachment has no release paper and can directly proceed to the next step of bonding; when the circular cutter mechanism 22 is selected for cutting, the circular cutter mechanism 22 moves above the adhesive paper along the first slide rail 5 under the action of the second limiting slider, the first bracket slides downward along the second bracket, and the circular cutter 221 on the first bracket also moves downward accordingly, completing the cutting of the adhesive layer and the release paper. The glass after attachment has release paper and can be stacked to save space and prevent the adhesive layer from failing.
