Description

Technical Field

[0001] The utility model relates to the technical field of gluing equipment, in particular to a multi-tape tensioning mechanism and a gluing device. Background Art

[0002] In an ultrasonic welding machine, a gluing device is required for gluing. During gluing, multiple film rolls unwind simultaneously, and a tape pulling mechanism pulls out a certain length of the tapes on the multiple film rolls, and then a gluing mechanism pastes the pulled-out tapes onto a product.

[0003] During the tape pulling process, the tapes may become loose. To improve the tension of the tapes, a tensioning mechanism is usually arranged between the unwinding mechanism and the tape pulling mechanism. The existing tensioning mechanism includes a pressure roller, a support and a cylinder. The pressure roller is rotatably connected to the support, and the support is arranged at the telescopic end of the cylinder. The pressure roller is horizontally arranged and located directly above the multiple tapes. The cylinder drives the support to descend to drive the pressure roller close to the tapes, so that the pressure roller presses the multiple tapes simultaneously, thereby improving the tension of multiple tapes.

[0004] However, when the existing tensioning mechanism presses multiple tapes, the tightness of each tape is different. When the cylinder drives the pressure roller to descend, the tightness of each tape will be inconsistent, resulting in an unsmooth tape pulling process, difficult tape cutting or wrinkling of the tapes during gluing, seriously affecting the gluing quality. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a multi-tape tensioning mechanism and a gluing device, which can ensure that each tape always maintains a tensioned state during tape pulling and improve the gluing quality.

[0033] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the creation of the present utility model can be interactively combined without conflicting with each other.

[0034] Referring to Figure 3 and Figure 4 , a multi-tape tensioning mechanism provided by an example of the present utility model includes a cross beam 1 and a plurality of pressing components 2 arranged on the cross beam 1. The plurality of pressing components 2 are respectively used to press a plurality of tapes 8. Specifically, the pressing component 2 includes a pressing roller 21 and a guiding module 22. The pressing roller 21 is placed on the tape 8, and the pressing roller 21 presses the tape 8 by its own gravity. The guiding module 22 is used to guide the pressing roller 21 to move in the vertical direction. Thus, it can ensure that each tape 8 is always in a tensioned state during tape pulling, improving the tape sticking quality.

[0035] In some preferred embodiments, the guiding module 22 includes a sliding rod 221 and a sliding sleeve 222 sleeved on the outer periphery of the sliding rod 221. The sliding sleeve 222 is arranged on the cross beam 1. The sliding rod 221 is vertically arranged. The bottom end of the sliding rod 221 is connected to the pressing roller 21, and the top end of the sliding rod 221 is provided with a convex platform 223 extending outward.

[0036] It can be understood that during tape pulling, under different tensions of the tape 8, the pressing roller 21 is driven to move up and down. At this time, the pressing roller 21 drives the sliding rod 221 to slide along the length direction of the sliding sleeve 222. Thus, the stability of the pressing roller 21 during up and down movement can be improved, preventing the pressing roller 21 from shifting. Moreover, the convex platform 223 provided at the top end of the sliding rod 221 can limit the movement range of the sliding rod 221, and further prevent the sliding rod 221 from detaching from the sliding sleeve 222.

[0037] In order to improve the convenience of assembly, the sliding rod 221 and the convex platform 223 are fixedly connected by bolts.

[0038] Further, a support 23 is provided between the slide bar 221 and the pressing roller 21. The bottom end of the slide bar 221 is fixedly connected to the support 23, and the pressing roller 21 is rotatably connected to the support 23. The support 23 can support the pressing roller 21. During the process of pulling the tape, the roller surface of the pressing roller 21 abuts against the tape 8. When the tape 8 moves, it drives the pressing roller 21 to rotate. Thus, the friction between the pressing roller 21 and the tape 8 can be reduced, the tape 8 can move smoothly, and at the same time, the surface quality of the tape 8 is improved.

[0039] Specifically, the support 23 is a U-shaped seat. A support shaft 24 is provided at the open end of the U-shaped seat. The pressing roller 21 is sleeved on the outer periphery of the support shaft 24, and the pressing roller 21 is rotatably connected to the support shaft 24. The support shaft 24 can support the entire pressing roller 21, improve the stability of the pressing roller 21, and reduce the deformation amount of the pressing roller 21.

[0040] More specifically, two bearings 25 are provided between the pressing roller 21 and the support shaft 24. The two bearings 25 are symmetrically arranged along the middle of the pressing roller 21. Thus, the force on the pressing roller 21 is uniform, and the smoothness of the pressing roller 21 during rotation is improved.

[0041] To improve the assembly convenience, the bottom of the slide bar 221 is fixedly connected to the U-shaped seat by bolts.

[0042] Refer to Figure 1 and Figure 2 Moreover, an example of the present utility model further provides a tape pasting device, which includes a fixing plate 3, a plurality of unwinding mechanisms 4 and a plurality of tape pulling mechanisms 5. The above-mentioned multi-tape tensioning mechanism and the plurality of unwinding mechanisms 4 are arranged on the fixing plate 3. The unwinding mechanism 4 is used for unwinding the tape 8, and the tape pulling mechanism 5 is used for clamping one end of the tape 8 and pulling it to the next working area. A plurality of pressing assemblies 2 are respectively located between the corresponding unwinding mechanisms 4 and the tape pulling mechanisms 5.

[0043] During tape pasting, a plurality of tape pulling mechanisms 5 simultaneously pull out a plurality of tapes 8, so that a plurality of unwinding mechanisms 4 unwind the tapes 8. At the same time, a plurality of pressing assemblies 2 respectively adjust the tension of a plurality of tapes 8. Thus, the tension of each tape 8 can be independently adjusted, avoiding the situation where the tightness of each tape 8 is inconsistent, and ensuring the tape pasting quality.

[0044] Further, the unwinding mechanism 4 includes an unwinding roller 41 and a damper 42. The unwinding roller 41 is rotatably connected to one side of the fixing plate 3, and the damper 42 is located on the other side of the fixing plate 3. The damper 42 is used to adjust the unwinding speed of the film roll. Thus, the tension of the tape 8 during tape pulling can be further improved.

[0045] Further, guide rollers 6 are respectively arranged on both sides of the pressing roller 21. The guide rollers 6 are arranged on the fixing plate 3. The pressing roller 21 and the guide rollers 6 are arranged in parallel. The guide rollers 6 on both sides of the pressing roller 21 can support the tape 8, so as to ensure that the pressing roller 21 can be in full contact with the tape 8.

[0046] Still further, a tape pressing mechanism 7 is arranged between the pressing assembly 2 and the tape pulling mechanism 5. The tape pressing mechanism 7 includes a support beam 71, a fixing block 72, a cylinder 73 arranged on the support beam 71, and a pressing block 74 arranged at the telescopic end of the cylinder 73. Both the support beam 71 and the fixing block 72 are fixed on the fixing plate 3. The pressing block 74 is located directly above the fixing block 72. The tape 8 passes between the pressing block 74 and the fixing block 72. The cylinder 73 drives the pressing block 74 to approach or move away from the fixing block 72 to press or loosen the tape 8.

[0047] When the cylinder 73 drives the pressing block 74 to approach the fixing block 72 to press the tape 8, it is convenient to cut the tape 8.

[0048] When the cylinder 73 drives the pressing block 74 to move away from the fixing block 72 to loosen the tape 8, it is convenient for the tape pulling mechanism 5 to pull the tape.

[0049] The above is a specific description of the preferred embodiment of the present invention, but the present invention is not limited to the described embodiment. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present invention. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
