Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape attachment, in particular to a double-sided adhesive tape attachment mechanism. Background Art

[0002] Double-sided adhesive tape, also known as adhesive paper or tape, is mainly a roll product made by applying glue on both sides of a certain substrate. Double-sided adhesive tape is made of paper, cloth, or plastic film as the substrate, and an elastomeric pressure-sensitive adhesive or resin-type pressure-sensitive adhesive is evenly coated on the above substrate to make a roll of adhesive tape. It is composed of three parts: substrate, adhesive, and release paper (film) or silicone paper. It is widely used in electronics, automobiles, home appliances, packaging and other industries.

[0003] Reference is made to Chinese patent authorization announcement number CN 218088251 U, which discloses a double-sided tape attachment mechanism, including a frame, the upper end of the frame is fixedly connected to an upper fixing seat, one side of the upper fixing seat is fixedly connected to a fixing column, the outer side of the fixing column is rotatably connected to a fixing sleeve through a bearing, the outer side of the fixing sleeve is fixedly connected to a telescopic column, one end of the telescopic column is fixedly connected to a limit ring, the lower end of the frame is fixedly connected to a wheel seat, and the inside of the wheel seat is rotatably connected to a clamping wheel through a pin. The double-sided tape attachment mechanism is provided with a telescopic column, so that the distance of the limit ring can be adjusted, making it more convenient and quick to fix the double-sided tape, and it can also fix double-sided tapes of different sizes, which greatly improves the use effect of the double-sided tape attachment mechanism.

[0004] By reviewing the above comparative documents, it can be seen that the prior art still has the following deficiencies. In the process of attaching the double-sided tape through the above device, the right end of the frame lacks a guide structure, and the tape can easily come into contact with the sharp parts of the upper right corner and the lower right corner of the frame, which not only causes the tape to be easily scratched, but also affects the smoothness of the tape when it is unfolded and attached. In addition, the tape on the tape roll is generally not used up at one time, so it needs to be divided into multiple sections and cut for multiple uses. When the previous section of the tape is attached, the attached tape is cut off. Since there is no limiting measure for the excess tape that has been unfolded on the tape roll, it is easy to make the excess tape difficult to reuse, resulting in serious waste of tape.

DETAILED DESCRIPTION

[0029] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0030] like Figure 1 , 3 As shown in Figure 4, in this embodiment, it includes a frame 1 and a rotating roller 4, the rotating roller 4 is arranged above the frame 1, the upper right end of the frame 1 is rotatably connected to the upper guide wheel 6, the lower right end of the frame 1 is rotatably connected to the lower guide wheel 7, a mesh pressure wheel 13 is provided below the frame 1, an operating rod 2 is fixed to the left end of the frame 1, a support frame 3 is fixed on the frame 1, the rotating roller 4 is rotatably connected to the upper end of the support frame 3, a plurality of spring return rods 20 are fixed on the periphery of the rotating roller 4, the ends of the spring return rods 20 are connected to tensioning plates 5, and the tensioning plates 5 are all arc-shaped.

[0031] When the double-sided tape is attached by the device, the tape roll with the wound double-sided tape is first installed on the periphery of the rotating roller 4, that is, after the tensioning plate 5 compresses the spring return rod 20, the rebound force of the spring return rod 20 will drive the tensioning plate 5 to be tightened on the inner wall of the tape roll, thereby completing the installation of the tape roll, and then the tape is pulled up and placed on the upper guide wheel 6 and the lower guide wheel 7, and the mesh pressure wheel 13 presses the tape at the same time, and then the operating rod 2 is held by hand to push the mechanism to the right, and the mesh pressure wheel 13 presses the tape and attaches it to the pre-bonded surface (such as Figure 4 As shown), during this process, the upper guide wheel 6 and the lower guide wheel 7 guide the tape, thereby preventing the tape from being scratched by the sharp parts of the frame 1 when being attached through the mechanism, and ensuring the smoothness of the tape during attachment.

[0032] like Figure 2 , 4 As shown, in this embodiment, an air pump 9 is fixed to the lower end of the frame 1, and the air suction port of the air pump 9 is connected to an air suction pipe 10. The end of the air suction pipe 10 is connected to a concave tube 11. The lower end of the concave tube 11 is rotatably connected and communicated with an axial tube 12. The mesh pressure wheel 13 is sleeved on the outer periphery of the axial tube 12, and a plurality of adsorption tubes 14 are connected between the mesh pressure wheel 13 and the axial tube 12.

[0033] During the process of tape attachment, the vacuum pump 9 is started at the same time. When the vacuum pump 9 is working, it will suck air through the vacuum pipe 10, the concave pipe 11, the shaft pipe 12 and the adsorption tube 14, and the suction force of the adsorption tube 14 is controlled to be only able to adsorb the tape. Before the tape is attached, it is adsorbed under the mesh pressure wheel 13. Once the tape is pressed and attached by the mesh pressure wheel 13, the adhesive force generated by the tape attachment is much greater than the force when the tape is adsorbed, so that the tape will be attached along the travel trajectory of the mesh pressure wheel 13, thereby preventing the tape from escaping from the pressing route of the mesh pressure wheel 13, and there is no need to manually adjust the attachment route of the tape, effectively ensuring the accuracy and convenience of tape attachment.

[0034] like Figure 4-7 As shown, in this embodiment, a tape cutting limit assembly is provided between the mesh pressure wheel 13 and the lower guide wheel 7, and the tape cutting limit assembly includes a concave plate 8, a cutter 16, a pasting plate 15, a return spring 18 and a pressure rod 19. The concave plate 8 is fixed to the lower end of the frame 1, the cutter 16 is fixed to the inner left wall of the concave plate 8, the pasting plate 15 is arranged at the inner right end of the concave plate 8, and a cutting groove 17 matching the cutter 16 is opened on the left side of the pasting plate 15. The return spring 18 is connected between the right side of the pasting plate 15 and the inner right wall of the concave plate 8, and the pressure rod 19 is fixed to the right side of the pasting plate 15. The pressure rod 19 slides to the right and passes through the right side of the concave plate 8.

[0035] During the process of tape attachment, the tape is passed through the concave plate 8, and the tape is located between the cutter 16 and the adhesive plate. After the tape is attached, the pressing rod 19 is pressed to drive the adhesive plate 15 close to the adhesive surface of the tape. After the adhesive surface of the tape contacts the adhesive plate 15, the tape adheres to the adhesive plate 15, and the cutter 16 cuts the tape into the cutting groove 17. At this time, the excess tape on the tape roll is attached to the adhesive plate 15 (such as Figure 7 As shown), the pasted tape is torn off from the pasting board 15 to complete the final bonding. In summary, it is not only convenient to cut off the pasted tape, but also convenient to limit the excess unfolded tape on the tape roll through the pasting board 15 to avoid the excess tape from being scattered, which is convenient for the next pasting work.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
