Description

Technical Field

[0001] This invention relates to the field of aluminum foil tape technology, specifically to a processing technology for aluminum foil tape. Background Technology

[0002] Aluminum foil tape is a type of tape made of aluminum foil with an adhesive coating. It is commonly used in various fields such as sealing materials, insulation, protective materials, and electronic products. Aluminum foil tape typically possesses properties such as waterproofing, fire resistance, high-temperature resistance, and corrosion resistance, and also has a certain degree of tear resistance, thus finding wide application in both industrial and household settings.

[0003] Aluminum foil tape has wide applications in the electronics industry. For example, as an electromagnetic shielding material, it can be used to isolate electromagnetic radiation and interference. It is commonly used for shielding electronic devices, communication equipment, cables, and electronic circuit boards to prevent electromagnetic radiation from interfering with internal electronic components or other equipment. However, the anti-shielding performance of existing aluminum foil tapes in the electronics industry is not stable due to their thickness: aluminum foil tape is relatively thin, so its anti-shielding ability is limited. Thicker shielding materials generally have better shielding performance, but this can affect the overall installation structure of electronic products. Furthermore, defects may exist in the manufacturing process of aluminum foil tape, such as tiny bubbles, flaws, or creases, which can reduce the shielding effect.

[0016] Compared with the prior art, the present invention provides a processing technology for aluminum foil tape, which has the following beneficial effects:

[0017] 1. The processing technology of this aluminum foil tape involves setting up unwinding rollers, feeding troughs, and nozzles. During the processing of the aluminum foil tape, a layer of magnetic tape can be applied to the surface of the traditional aluminum foil tape. This magnetic tape has a certain shielding effect. The magnetic material in the magnetic tape can absorb and suppress the propagation of electromagnetic waves, thereby reducing the possibility of waves passing through. Then, a layer of ferrite powder is sprinkled between the magnetic tape and the aluminum foil tape. This powder increases the thickness and density of the shielding layer, further blocking the propagation of electromagnetic waves, making it more suitable for use in electronic products.

[0018] 2. The processing technology of this aluminum foil tape, by installing limiting components, can block both sides of the aluminum foil tape during winding, so that the adhesive and ferrite powder can accurately fall on the surface of the aluminum foil tape, thus improving accuracy. By controlling the pressure inside the sliding groove, the lateral pressure of the positioning plate on the aluminum foil tape can be adjusted, so as to enable lateral positioning of aluminum foil tapes of different widths, thus improving flexibility.

[0019] 3. The processing technology of this aluminum foil tape, through the installation of a drive component, allows the dual-axis motor to vibrate the collection box and pressurize the inside of the liquid storage tank when it starts. By vibrating the collection box, the ferrite powder inside the collection box can fall evenly, and by pressurizing the inside of the liquid storage tank, the adhesive inside the liquid storage tank can be sprayed evenly, thus enhancing energy efficiency.

Rollers 56 are rotatably connected equidistantly inside the positioning plates 54. The surface of the rollers 56 extends into the interior of the inclined grooves 55.

By installing the limiting component 5, the two sides of the aluminum foil tape can be blocked when the aluminum foil tape is wound up, so that the adhesive and ferrite powder can fall accurately on the surface of the aluminum foil tape, which enhances the accuracy. By controlling the pressure inside the sliding groove 52, the side pressure of the positioning plate 54 on the aluminum foil tape can be adjusted, so that aluminum foil tapes of different widths can be positioned laterally, which enhances the flexibility.

By setting the unwind roller 4, the feeding trough 9 and the nozzle 15, etc., when processing aluminum foil tape, a layer of magnetic tape can be covered on the surface of the traditional aluminum foil tape. This layer of magnetic tape has a certain shielding effect. The magnetic material in the magnetic tape can absorb and suppress the propagation of electromagnetic waves, thereby reducing the possibility of waves passing through. Then, a layer of ferrite powder is sprinkled between the magnetic tape and the aluminum foil tape. These powders increase the thickness and density of the shielding layer, further blocking the propagation of electromagnetic waves, so that it can be better applied to electronic products.

[0032] A drive assembly 16 is installed inside the fixed box 6. The drive assembly 16 includes a dual-axis motor 161 fixedly installed inside the fixed box 6. A vibration assembly 162 is installed at one output end of the dual-axis motor 161. The vibration assembly 162 includes a vibrating plate 1621 fixedly connected to the surface of the collection box 8. A rotating groove 1622 is formed inside the vibrating plate 1621. A cam 1623 is fixedly connected to the output end of the dual-axis motor 161. The rotating groove 1622 is elliptical. The outer surface of the cam 1623 is rotatably connected to the inside of the rotating groove 1622. The surface of the cam 1623 is in contact with the inner wall of the rotating groove 1622. A protruding plate 163 is fixedly connected to the other output end of the dual-axis motor 161. A connecting rod 164 is rotatably connected to the surface of the protruding plate 163. A sealing block 165 is movably connected to the end of the connecting rod 164 away from the protruding plate 163. A sealing groove 166 is formed inside the fixed box 6. The internal structure is fixedly installed with a connecting pipe 167 that communicates with the inside of the sealing groove 166. A first one-way valve 168 is fixedly installed inside the connecting pipe 167. The input end of the first one-way valve 168 is close to the inside of the sealing groove 166. An air inlet pipe 169 is fixedly connected inside the fixed box 6. A second one-way valve 1610 is fixedly installed inside the air inlet pipe 169. The output end of the second one-way valve 1610 is close to the inside of the sealing groove 166. The inside of the sealing groove 166 is connected to the inside of the liquid storage tank 13 through the connecting pipe 167. By installing the drive assembly 16, when the dual-shaft motor 161 is started, it can vibrate the collection box 8 and pressurize the inside of the liquid storage tank 13. By vibrating the collection box 8, the ferrite powder inside the collection box 8 can fall evenly. By pressurizing the inside of the liquid storage tank 13, the adhesive inside the liquid storage tank 13 can be sprayed out evenly, thus enhancing energy efficiency.

[0033] A fixing block 17 is fixedly connected to the surface of the main body 1 of the aluminum foil tape processing equipment. A rotating rod 18 is rotatably connected to the surface of the fixing block 17. A roller 19 is rotatably connected to the top of the rotating rod 18. A tension spring 20 is fixedly connected to the surface of the rotating rod 18. The end of the tension spring 20 away from the rotating rod 18 is fixedly connected to the surface of the main body 1 of the aluminum foil tape processing equipment. After the aluminum foil tape is finally rolled up, it is pressed against the roller 19, so that the aluminum foil tape can be tightly bonded to the magnetic tape by the adhesive.

[0034] In summary, during the processing of this aluminum foil tape, before winding the aluminum foil tape, the pressure between the two positioning plates 54 is adjusted according to the width of the aluminum foil tape. During adjustment, the first electric telescopic rod 58 is activated to drive the adjusting plate 59 to slide, which can adjust the pressure inside the adjusting cavity 57 and the sliding groove 52. By installing the limiting component 5, the two sides of the aluminum foil tape can be blocked when the aluminum foil tape is wound, so that the adhesive and ferrite powder can accurately fall on the surface of the aluminum foil tape, which enhances the accuracy. By controlling the pressure inside the sliding groove 52, the side pressure of the positioning plate 54 on the aluminum foil tape can be adjusted, so that the aluminum foil tape of different widths can be laterally positioned, which enhances the flexibility.

[0035] During winding, the aluminum foil tape is wound directly by starting the winding roller 2, and the magnetic tape on the unwinding roller 4 is also fixed to the aluminum foil tape. When the winding roller 2 rotates, it will rotate together with the unwinding roller 4. At this time, by starting the drive assembly 16, the dual-axis motor 161 can drive the cam 1623 to rotate inside the rotating groove 1622, which can drive the vibrating plate 1621 to move up and down at high frequency, which can drive the collection box 8 to vibrate inside the silicone box 7. While vibrating the collection box 8, the rotation of the dual-axis motor 161 can drive the convex plate 163 to rotate. The rotation of the convex plate 163 drives the sealing block 165 to rotate through the traction of the connecting rod 164. When the sealing block 165 moves downwards, the second one-way valve 1610 closes and the first one-way valve 168 opens. Conversely, when the sealing block 165 moves downwards, the second one-way valve 1610 opens and the first one-way valve 168 closes. Therefore, when the sealing block 165 moves, it can pressurize the inside of the liquid storage tank 13. By vibrating the collection box 8, the ferrite powder inside the collection box 8 can fall evenly. By pressurizing the inside of the liquid storage tank 13, the adhesive inside the liquid storage tank 13 can be sprayed evenly, which enhances energy saving. Finally, after the coated aluminum foil tape is wound up, it is pressed against the roller 19, so that the aluminum foil tape can be tightly bonded to the magnetic tape by the adhesive.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
