Description

Technical Field

[0001] This utility model relates to the field of conductive cloth composite absorbing sheet manufacturing technology, and in particular to a mobile phone conductive cloth composite absorbing sheet. Background Technology

[0002] Mobile phone conductive cloth composite absorbing sheet is an integrated functional material that combines conductive cloth and absorbing material. It is mainly used to solve electromagnetic interference and signal optimization problems inside mobile devices.

[0003] In the manufacturing process of existing mobile phone conductive cloth composite absorbing sheets, the absorbing sheet, transparent release film, transparent adhesive and conductive cloth are usually cut and rolled together by using rollers and laser cutting blades.

[0004] However, when laser cutting is used to cut microwave absorbing sheets, transparent release films, transparent adhesives and conductive cloth, because the microwave absorbing sheets are composite materials, small debris is easily generated on the material surface during high-temperature cutting. This causes air bubbles to easily form in the material during rolling, which in turn affects the production effect of conductive cloth composite microwave absorbing sheets. Utility Model Content

[0005] Therefore, it is necessary to provide a mobile phone conductive cloth composite absorbing sheet to address the problem that fine debris is easily generated on the material surface during high-temperature cutting of the absorbing sheet, which leads to the formation of air bubbles in the material during rolling.

[0006] The device includes: a production table, the surface of which is provided with a laser cutting mechanism; and an adsorption mechanism, which includes dust collection frames fixedly connected to the front end of the production table in equal rows, a fan connected to the top of each dust collection frame, a dust collection pipe fixedly connected to the inner wall of each dust collection frame, a dust collection frame slidably connected to the inner wall of each dust collection frame, the inner wall of each dust collection frame slidably connected to the surface of the dust collection pipe, and a filter frame slidably connected to the upper end of the inner wall of each dust collection frame.

[0007] In one embodiment, the inner wall of the production table is rotatably connected with a plurality of limiting rollers.

[0008] In one embodiment, two rubber frames are slidably connected to the inner wall of the dust collection frame, and the surface of the rubber frames is snapped into the inner wall of the dust collection frame.

[0009] In one embodiment, two springs are fixedly connected to one end of the rubber frame, and the other end of the springs is fixedly connected to the inner wall of the dust collection frame.

[0010] In one embodiment, a locking rod is slidably connected to the inner wall of the rubber frame, and the surface of the locking rod engages with the inner wall of the dust collection frame. Through the cooperation of the locking rod, the rubber frame, and the spring, the dust collection frame and filter frame are cleaned, thereby ensuring that the exhaust fan and suction pipe adsorb the debris generated during cutting, preventing the debris from falling onto the material surface.

[0011] In one embodiment, a plurality of pressure blocks are slidably connected to the upper end of the inner wall of the dust collection frame, and the bottom of the pressure blocks contacts the top of the filter frame.

[0012] In one embodiment, a shielding block is fixedly connected to both sides of the rubber frame, with one side of the shielding block contacting one side of the dust collection frame. The shielding block seals the open areas on both sides of the dust collection frame, preventing impurities from adhering to the spring surface.

[0013] In one embodiment, a fixing rope is fixedly connected to one end of the clamping rod, and the other end of the fixing rope is fixedly connected to the front end of the rubber frame. The fixing rope restricts the placement of the clamping rod, preventing it from being lost.

[0014] Beneficial effects 1. By using a combination of a blower, a suction pipe, a suction frame, a dust collection frame, and a filter frame, the debris generated during laser cutting is adsorbed, preventing the debris from falling onto the material surface and thus avoiding the formation of air bubbles in the material during rolling, thereby ensuring the production effect of the conductive cloth composite absorbing sheet. 2. The moving material is pressed and limited by the limiting roller to prevent the material from shifting when the dust suction pipe is adsorbing surrounding debris, thus ensuring the rolling effect of the material and ensuring the production effect of the conductive cloth composite absorbing sheet.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figures 1-5 This invention describes a mobile phone conductive cloth composite absorbing sheet.

[0020] In one embodiment, a mobile phone conductive cloth composite absorbing sheet includes: a production table 100, the surface of which is provided with a laser cutting mechanism 200; and an adsorption mechanism 300, which includes dust collection frames 301 fixedly connected to the front end of the production table 100 and arranged in equal rows. The top of the dust collection frames 301 is connected to an exhaust fan 303, the inner wall of the dust collection frames 301 is fixedly connected to a dust collection pipe 302, the inner wall of the dust collection frames 301 is slidably connected to a dust collection frame 304, the inner wall of the dust collection frame 304 is slidably connected to the surface of the dust collection pipe 302, and the upper end of the inner wall of the dust collection frame 304 is slidably connected to a filter frame 305.

[0021] It should be noted that the production table 100 includes a base platform, and the top of the base platform is equipped with two mounting plates. The mounting plates are installed on the top of the base platform by bolts. Several pressure rollers and positioning rods are rotatably connected to the inner wall of the mounting plates. The surfaces of the corresponding positioning rods are respectively engaged with the following rollers: wave-absorbing sheet roller, waste release film roller, transparent release film roller, transparent film roller, wave-absorbing sheet waste roller, single-sided conductive cloth roller, single-sided conductive cloth waste roller, double-layer protective film roller, double-layer protective film waste roller, product shape waste roller, single-layer protective film roller, and single-layer protective film waste roller.

[0022] The laser cutting mechanism 200 includes five electric guide rails fixedly connected to the inner surface of the production table 100. A slider is slidably connected to the surface of the electric guide rail. Both ends of the slider are fixedly connected to accordion sleeves. The other end of the accordion sleeve is fixedly connected to the end of the electric guide rail. A laser cutting blade is installed on one side of the slider.

[0023] It should be noted that electric guide rails typically consist of a guide rail body, a slider, a drive motor, a transmission device, and a control system.

[0024] Transmission device: responsible for converting the rotational motion of the motor into linear motion. Common transmission methods include screw drive, belt drive, chain drive, etc.

[0025] Control system: The control system is used to control the operation of the motor and achieve precise control of the linear motion of the slider. It can set parameters such as the slider's speed, stroke, and acceleration according to user needs, and monitor the slider's position and status in real time through sensors. This is a relatively common and well-known technology in this field and is not closely related to the technical problem of this application; therefore, it has not been described in detail.

[0026] A laser cutting head typically consists of a nozzle, focusing lens, collimating lens, protective lens, height sensor, and gas channel.

[0027] The nozzle, located at the very tip of the cutting head, is used to inject auxiliary gas at a specific pressure and shape into the cutting area. The auxiliary gas blows away slag and debris generated during the cutting process, while also cooling the cutting area to prevent excessive burning and oxidation of the material.

[0028] A focusing lens focuses a laser beam onto the material surface, concentrating the laser energy for highly efficient cutting. The focal length of the focusing lens affects the focusing effect and cutting depth of the laser beam, and must be selected based on specific cutting requirements.

[0029] Collimating lenses are used to convert diverging laser beams emitted from a laser into parallel beams to ensure the stability and consistency of the laser during transmission and reduce energy loss.

[0030] The protective lens is installed above the focusing lens. Its main function is to prevent slag, debris, and fumes generated during the cutting process from contaminating the focusing lens and extending its service life. The protective lens is usually removable and replaceable.

[0031] A height sensor is used to monitor the distance between the cutting head and the material surface in real time, and the height of the cutting head is automatically adjusted by the control system to ensure that the laser focus always falls accurately on the material surface during the cutting process, thereby improving the stability of the cutting quality.

[0032] The gas channel is used to transport auxiliary gas, including a pipe connected to the gas source and an internal gas distribution system, to ensure that the auxiliary gas can reach the nozzle evenly and stably. This is a well-known technology that is common in the field and is not closely related to the technical problem of this application. Therefore, it has not been described in detail.

[0033] In this embodiment, the conductive cloth composite absorbing sheet material for mobile phones needs to be manufactured. Through the corresponding installation process, two absorbing sheet rollers, two absorbing sheet waste collection rollers, one waste release film collection roller, one transparent release film roller, three transparent adhesive rollers, one single-sided conductive cloth roller, one single-sided conductive cloth waste collection roller, one double-layer protective film roller, one double-layer protective film waste collection roller, one product shape waste collection roller, one single-layer protective film roller, and one single-layer protective film waste collection roller are installed at the corresponding positions on the manufacturing table 100.

[0034] The rollers on the production table 100 are rotated and the laser cutting mechanism 200 and the exhaust fan 303 are turned on, so that the absorbing sheet, transparent release film and transparent adhesive are rolled together in the first step. The first laser cutting mechanism 200 cuts the absorbing sheet to the corresponding size according to the pre-set cutting process. The waste generated during the cutting is rolled up by the corresponding waste collection roller. At this time, the exhaust fan 303 is turned on to extract the excess air inside the dust collection frame 301 and the dust collection frame 304, so that the dust collection frame 301 and the dust collection frame 304 form a negative pressure, so that the dust collection pipe 302 extracts the debris generated during the laser cutting and prevents the debris from falling on the absorbing sheet.

[0035] The cut microwave absorbing sheet, transparent release film and transparent adhesive are conveyed so that the second wave microwave absorbing sheet and transparent adhesive are attached to the composite material in sequence and rolled. At this time, the second wave laser cutting mechanism 200 cuts the combined second wave microwave absorbing sheet to the corresponding size according to the pre-set cutting process. The waste generated during the cutting is rolled up by the corresponding waste collection roller. The adsorption mechanism 300 adsorbs the debris generated during the cutting in the above manner.

[0036] The cut material is conveyed onto the material, where single-sided conductive cloth and transparent adhesive are rolled onto the material in sequence. The third-wave laser cutting mechanism 200 cuts the assembled material to the corresponding size according to the pre-set cutting process. Waste generated during cutting is collected by the corresponding waste collection roller. The adsorption mechanism 300 adsorbs the debris generated during cutting in the above manner.

[0037] The fourth-wave laser cutting mechanism 200 cuts the double-layer protective film in the conveying process to the corresponding size according to the pre-set cutting process. The waste generated during the cutting process is rolled up by the corresponding waste collection roller and conveyed and rolled on the composite material. The adsorption mechanism 300 adsorbs the debris generated during the cutting process in the above manner.

[0038] The fifth-wave laser cutting mechanism 200 cuts the composite material to the corresponding dimensions according to the pre-set cutting process. The waste generated during cutting is then rolled up by the corresponding waste collection roller. At this time, a single-layer protective film is rolled onto the composite material to produce a conductive cloth composite absorbing sheet, which is then rolled up to avoid the formation of air bubbles during the production of the conductive cloth composite absorbing sheet. This ensures that the conductive cloth composite absorbing sheet has good performance, enabling electronic, electromagnetic, and shielding products to have grounding, conductivity, and shielding functions. It also has excellent bending performance, capable of being bent more than 1000 times. In the manufactured conductive cloth composite absorbing sheet, the conductive cloth serves as the substrate, and the pressure-sensitive layer is a high-performance polymer pressure-sensitive material, compounded with high-performance alloy powder materials, which has excellent conductivity and adhesion properties, ensuring that the product is firmly and stably attached to the protected material.

[0039] like Figure 2 As shown, the inner wall of the production table 100 is rotatably connected with several limiting rollers 306.

[0040] In this embodiment, the limiting roller 306 rolls and limits the moving material to prevent the suction pipe 302 from adsorbing surrounding waste and causing the material to shift.

[0041] like Figure 4-5 As shown, two rubber frames 307 are slidably connected to the inner wall of the dust collection frame 304. The surface of the rubber frame 307 is snapped into the inner wall of the dust collection frame 301. Two springs 308 are fixedly connected to the end of the rubber frame 307. The other end of the spring 308 is fixedly connected to the inner wall of the dust collection frame 304. A locking rod 311 is slidably connected to the inner wall of the rubber frame 307. The surface of the locking rod 311 is snapped into the inner wall of the dust collection frame 304. Several pressure blocks 309 are slidably connected to the upper end of the inner wall of the dust collection frame 304. The bottom of the pressure block 309 contacts the top of the filter frame 305. Covering blocks 310 are fixedly connected to both sides of the rubber frame 307. One side of the covering block 310 contacts one side of the dust collection frame 304. A fixing rope 312 is fixedly connected to one end of the locking rod 311. The other end of the fixing rope 312 is fixedly connected to the front end of the rubber frame 307.

[0042] The dust collection frame 304, spring 308 and clamping rod 311 are all polyurethane rubber components, which have excellent elasticity and sealing performance, ensuring that the dust collection frame 304 is tightly attached to the inner wall of the suction frame 301, the inner wall of the dust collection frame 304 is tightly attached to the surface of the suction pipe 302, and the inner wall of the dust collection frame 304 is tightly attached to the surface of the filter frame 305.

[0043] In this embodiment, when it is necessary to clean the dust collection frame 304 and the filter frame 305, pull the lever 311 away from the dust collection frame 304, pull the two rubber frames 307 closer to each other, so that the rubber frames 307 are away from the suction frame 301, pull the dust collection frame 304 away from the suction frame 301 and the suction pipe 302, at this time pull the multiple pressure blocks 309 to release the restriction on the filter frame 305, pull the filter frame 305 up and away from the dust collection frame 304, and the dust collection frame 304 and the filter frame 305 can be cleaned.

[0044] After cleaning, slide the filter frame 305 into the dust collection frame 304, push the pressure block 309 against the top of the filter frame 305, slide the dust collection frame 304 into the suction frame 301, so that the inner wall of the dust collection frame 304 slides into the surface of the suction pipe 302, and the elastic force of the spring 308 pushes the rubber frame 307 to move and lock it in the suction frame 301, thereby locking the dust collection frame 304 in the suction frame 301.

[0045] Working principle: The laser cutting mechanism 200 cuts the absorbing sheet to the corresponding size according to the pre-set cutting process. The waste generated during the cutting is rolled up by the corresponding waste collection roller. At this time, the exhaust fan 303 is turned on to extract the excess air inside the dust collection frame 301 and the dust collection frame 304, so that the extracted air is discharged and a negative pressure is formed inside the dust collection frame 301 and the dust collection frame 304. This causes the dust collection pipe 302 to extract the debris generated during the laser cutting, preventing the debris from falling onto the absorbing sheet.

[0046] It should be noted that the production table 100, exhaust fan 303, electric guide rail, slider, bellows sleeve and laser cutting blade mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the exhaust fan 303, electric guide rail and laser cutting blade can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
