Description

Technical Field

[0001] The utility model relates to the technical field of conductive tape processing, in particular to a glue coating device for conductive tape processing. Background Art

[0002] Conductive tape, a key component in electronic and electrical products, is widely used in computers, mobile phones, wires, cables, and other fields. Its properties include excellent conductivity and shielding effectiveness, anti-friction properties, metal bonding, as well as good processability and a soft texture. However, in the production of conductive tape, the adhesive coating step is particularly critical, directly affecting the tape's quality and performance. Therefore, the development and optimization of adhesive coating equipment for conductive tape processing is of great significance for improving conductive tape production efficiency and product quality.

[0003] Patent No. CN213943771U discloses a gluing device for processing conductive aluminum foil tape, comprising a base, two fixed brackets fixedly connected to the top of the base, and three sets of fixed brackets, each set of two fixed brackets. A guide roller is disposed between each of the three sets of fixed brackets, and a roller and a take-up roller are disposed between each of the other two sets of fixed brackets. The guide roller, roller, and take-up roller are connected to the outer walls of the aluminum foil tape body. The above-mentioned technology uses a motor to drive a rotating rod to rotate the drive roller, thereby adjusting the tension of the aluminum foil tape body during transmission. A first electric push rod drives the gluing roller and the cooling roller to descend, pressing the aluminum foil tape body and applying glue to the aluminum foil tape body. A second electric push rod drives the pressure plate to descend, so that the rollers and the aluminum foil tape body are bonded, and the glue is evenly applied, improving and maintaining the gluing quality. The cooling air generated by the fan accelerates the drying efficiency of the glue, ensuring high-quality and efficient production of the tape.

[0004] However, the above technology still has the following problems:

[0005] During the process of gluing the conductive tape, the conductive tape is moved by the rotation of the unwinding roller and the receiving roller. During the movement, the conductive tape may become loose, resulting in poor gluing effect, thereby affecting the quality of the product. In addition, the excess glue on the conductive tape is not cleaned, resulting in waste of glue. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the utility model provides a gluing device for processing a conductive tape, which prevents the conductive tape from loosening during the gluing process and reduces glue waste.

[0009] Furthermore, a rubber anti-slip pad is fixedly connected to the surface of the rotating shaft.

[0010] Furthermore, there are two lifting assemblies, which are fixed on two support plates respectively and located below the slide groove.

[0011] Furthermore, the lifting assembly includes a high-precision cylinder fixed on the side of the support plate, the output end of the high-precision cylinder is fixedly connected to a connecting block, and both ends of the scraper are fixedly connected to the connecting block.

[0012] Furthermore, a sealing plate is fixedly connected to the scraper at the side of the chute.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This gluing device for processing conductive tape uses a tensioning mechanism to exert force on the back of the conductive tape, so that the conductive tape is always kept in a tensioned state during the gluing process, thereby ensuring the uniformity of the gluing.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figures 1 to 5 A gluing device for processing conductive tape comprises two parallel support plates 1, on which a discharge roller 2, a receiving roller 3, a transmission roller 4 and a gluing roller 5 are provided. The gluing roller 5 is located directly below the discharge roller 2, and a glue groove 6 is provided below the gluing roller 5. A tensioning mechanism 7 is fixedly connected to the support plate 1, and a slide groove 8 is provided on the surface of the two support plates 1. A lifting component 9 is fixedly connected to the side of the support plate 1, and a scraper 10 is fixedly connected to the upper end of the lifting component 9. The scraper 10 is slidably connected in the slide groove 8, and the scraper 10 is located above the glue groove 6.

[0023] The structure of the conductive tape processing gluing device in the present invention is similar to that of the existing conductive aluminum foil tape processing gluing device, such as the patent with announcement number CN213943771U which discloses a conductive aluminum foil tape processing gluing device. The main improvement of the present invention is that by using the tensioning mechanism 7 to exert force on the back of the conductive tape, the conductive tape is always kept in a tensioned state during the gluing process, thereby ensuring the uniformity of the gluing. Under the action of the scraper 10, the excess glue on the conductive tape is scraped into the glue groove 6 for reuse, thus avoiding waste. Figures 1 to 5As shown, the gluing device for processing conductive tape in the present invention, when in use, first press the tensioning mechanism 7 downward so that the first support rod 705 is in a horizontal state, and tighten the tightening bolt 708 to fix it. At this time, the first torsion spring 703 and the second torsion spring 704 store energy, and then the conductive tape on the unwinding roller 2 is connected to the receiving roller 3 from the surface of the transmission roller 4 in turn, and the tension of the conductive tape is adjusted, and the restriction of the tightening bolt 708 on the first support rod 705 and the second support rod 706 is released. The first torsion spring 703 and the second torsion spring 704 release energy, so that the first support rod 705 and the second support rod 706 rotate upward around the connecting rod 701, thereby making the rotating shaft 707 and the back of the conductive tape rotate. When the conductive tape becomes loose during the gluing process, the first torsion spring 703 and the second torsion spring 704 will continue to release energy, so that the first support rod 705 and the second support rod 706 continue to rotate upward around the connecting rod 701, so as to always keep the rotating shaft 707 applying a supporting force to the conductive tape, thereby ensuring that the conductive tape is always in a tensioned state. Before gluing, the high-precision cylinder 901 is driven first, and the high-precision cylinder 901 moves the connecting block 902, so that the scraper 10 moves along the slide groove 8 to adjust the distance between the scraper 10 and the conductive tape, so as to determine the thickness of the glue, and scrape the excess glue back into the glue groove 6 for continued use.

[0024] like Figure 1 or Figure 3 As shown, the tensioning mechanism 7 includes a connecting rod 701 fixedly connected between the two support plates 1, a sleeve 702 fixedly connected in the middle of the connecting rod 701, a first torsion spring 703 and a second torsion spring 704 fixedly connected on both sides of the sleeve 702, and a first support rod 705 and a second support rod 706 rotatably connected at both ends of the connecting rod 701, the output end of the first torsion spring 703 is fixedly connected to the first support rod 705, the output end of the second torsion spring 704 is fixedly connected to the second support rod 706, a rotating shaft 707 is rotatably connected between the first support rod 705 and the second support rod 706, and a tightening bolt 708 is threadedly connected on the first support rod 705 and the second support rod 706.

[0025] Specifically, after the conductive tape is installed, the restriction of the tightening bolt 708 on the first support rod 705 and the second support rod 706 is released, and the first torsion spring 703 and the second torsion spring 704 release energy, so that the first support rod 705 and the second support rod 706 rotate upward around the connecting rod 701, so that the rotating shaft 707 is in contact with the back of the conductive tape and applies a certain supporting force to the conductive tape. When the conductive tape becomes loose during the gluing process, the first torsion spring 703 and the second torsion spring 704 will continue to release energy, so that the first support rod 705 and the second support rod 706 continue to rotate upward around the connecting rod 701, thereby always keeping the rotating shaft 707 applying supporting force to the conductive tape, thereby ensuring that the conductive tape is always in a tensioned state.

[0026] like Figure 3 As shown, a rubber anti-slip pad 11 is fixedly connected to the surface of the rotating shaft 707 .

[0027] Specifically, the rubber anti-slip pad 11 can prevent the rotating shaft 707 from damaging the conductive tape.

[0028] like Figure 4 As shown, there are two lifting assemblies 9 , which are fixed on two support plates 1 respectively and are located below the slide trough 8 .

[0029] Specifically, the two lifting assemblies 9 jointly lift the scraper 10 to change the position of the scraper 10 in the vertical direction.

[0030] like Figure 5 As shown, the lifting assembly 9 includes a high-precision cylinder 901 fixed on the side of the support plate 1, the output end of the high-precision cylinder 901 is fixedly connected to a connecting block 902, and both ends of the scraper 10 are fixedly connected to the connecting block 902.

[0031] Specifically, before applying the glue, the high-precision cylinder 901 is driven first. The high-precision cylinder 901 moves the connecting block 902, thereby moving the scraper 10 along the slide groove 8 to adjust the distance between the scraper 10 and the conductive tape, thereby determining the thickness of the glue, and scraping the excess glue back into the glue groove 6 for continued use. The glue layer on the conductive tape is relatively thin, and the high-precision cylinder 901 can effectively control the distance between the scraper 10 and the conductive tape.

[0032] like Figure 5 As shown, a sealing plate 12 is fixedly connected to the scraper 10 on the side of the chute 8.

[0033] Specifically, the sealing plate 12 can prevent glue on the scraper 10 from accumulating and flowing into the chute 8, making it difficult to clean it.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
