[0001] This utility model relates to the technical field of breathable membrane bonding equipment, and in particular to a dustproof, waterproof and breathable membrane bonding device for earpieces. Background Technology
[0002] Breathable membrane lamination equipment is a specialized mechanical device used to precisely adhere breathable membranes to the surface of products.
[0003] Utility model patent CN216637153U discloses an automatic breathable film laminating device. The key technical features include: a frame with a worktable, a feeding assembly, a discharging assembly, a breathable film cutting device, an unwinding device, a winding device, a transfer assembly, and a hot-pressing assembly. The worktable has a flow channel along the X-axis. The feeding and discharging assemblies are located at opposite ends of the flow channel. The feeding assembly includes a feeding track connected to the flow channel, and the discharging assembly includes a discharging flow channel connected to the flow channel. The breathable film cutting device, unwinding device, and winding device are located on the same side of the flow channel, with the cutting device positioned between the unwinding and winding devices. The transfer assembly includes a suction nozzle movable along the Y-axis and Z-axis. The hot-pressing assembly is located directly above the worktable and has a hot-pressing head that can move up and down along the Z-axis. This automatic breathable film laminating device significantly improves the production efficiency of air valves to meet market demands, enhances the lamination accuracy between the breathable film and the air valve, and improves product quality.
[0004] Regarding the aforementioned content, the following technical defects exist: The dustproof and waterproof breathable membrane is designed to protect the earpiece from external contaminants such as moisture and dust while maintaining the device's breathability and ensuring unaffected sound quality. Generally, before attaching the breathable membrane to the earpiece, the membrane tube is first fixed to the bonding mechanism, and then the double-sided adhesive tube is fixed to the power mechanism. Under the action of rollers, the bonding mechanism adheres the dustproof and waterproof breathable membrane of the membrane tube to the double-sided adhesive on the double-sided adhesive tube. The double-sided adhesive helps to firmly adhere the breathable membrane to the earpiece. To ensure there are no gaps between the membrane and the earpiece surface and prevent moisture and dust from entering through the membrane edges, it was found during the bonding process of the double-sided adhesive and the breathable membrane using a bonding mechanism. The existing bonding mechanism uses small-diameter rollers for coating and applying pressure. After completing the above operations, during the final product breathable membrane functional testing stage, acoustic and air pressure tests frequently fail. This also leads to instability and substandard results for breathable membranes with double-sided adhesive produced by using small-diameter rollers in the bonding mechanism.
[0005] Therefore, it is necessary to provide a new dustproof, waterproof, and breathable membrane bonding device for earpieces to solve the above-mentioned technical problems. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies. In the process of bonding double-sided adhesive to a breathable membrane using a bonding mechanism with a small diameter roller, the existing mechanism, which applies the film and pressure, frequently fails acoustic and air pressure tests during the final functional testing stage of the breathable membrane. This results in instability and defects in the breathable membrane produced using a small-diameter roller in the bonding mechanism.
[0007] To solve the above technical problems, this utility model provides a dustproof, waterproof, and breathable membrane bonding device for earpieces, comprising: a bonding mechanism, two support plates mounted on the upper surface of the bonding mechanism, a power mechanism mounted on one side of one of the support plates, a double-sided adhesive tube mounted on the output end of the power mechanism, a breathable membrane tube mounted on the output end of the bonding mechanism, an adjustment mechanism provided on the side of the support plate away from the power mechanism, the adjustment mechanism including a mounting plate, the mounting plate being fixedly connected to the side of the two support plates away from the power mechanism, a motor being fixedly connected to one side of the mounting plate, a power rod being fixedly connected to the output end of the motor, a plurality of limiting holes being opened at one end of the arc surface of the power rod, the plurality of limiting holes being evenly distributed at one end of the arc surface of the power rod, a roller being slidably connected to the arc surface of the power rod, three guide grooves being opened on one inner wall of the roller, a plurality of guide rods being slidably connected to the inner wall of the guide grooves, the plurality of guide rods being evenly distributed on the power rod, and the guide rods being fixedly connected to the power rod. Three slots are provided on one side of the roller. A limit rod is slidably connected to the inner wall of each slot. One end of the arc surface of the limit rod is fixedly connected to the arc surface of the power rod. Several fixing blocks are fixedly connected to one side of the other inner wall of the roller, and these fixing blocks are evenly distributed on one side of the inner wall. A sliding plate is slidably connected to the arc surface of the power rod. A slider slides through the inner wall of the sliding plate. A pressing ring is fixedly connected to one side of the slider. A first spring is fitted onto one end of the arc surface of the sliding plate. The two ends of the arc surface are fixedly connected to the sliding plate and the pressing ring, respectively. Several assembly pieces are fixedly connected to the side of the sliding plate near the pressing ring. The assembly pieces are evenly distributed on the sliding plate. The assembly pieces are elastic pieces. The side of the assembly piece is provided with a positioning hole. A connecting rod slides through the inner wall of the positioning hole. One end of the arc surface of the connecting rod is fixedly connected to one end of the inner wall of the roller. A rotating rod is threaded through the inner wall of the slider. One end of the arc surface of the rotating rod is threaded through the inner wall of one of the limiting holes.
[0008] The aforementioned components achieve the following effects: A dustproof and waterproof breathable membrane protects the earpiece from external contaminants such as moisture and dust while maintaining the device's breathability and ensuring unaffected sound quality. Generally, before attaching the breathable membrane to the earpiece, the membrane tube is first fixed to the bonding mechanism, and then the double-sided adhesive tube is fixed to the power mechanism. Under the action of rollers, the bonding mechanism adheres the dustproof and waterproof breathable membrane of the membrane tube to the double-sided adhesive on the double-sided adhesive tube. The double-sided adhesive helps to firmly adhere the breathable membrane to the earpiece, ensuring no gaps between the membrane and the earpiece surface, preventing moisture and dust from entering through the membrane edges. However, during the bonding process of the double-sided adhesive and the breathable membrane through the bonding mechanism... Currently, existing bonding mechanisms use small-diameter rollers for lamination and pressure application. After completing these operations, during the final product testing stage of the breathable membrane, acoustic and air pressure tests frequently fail. This results in instability and defects in the double-sided adhesive breathable membrane produced using small-diameter rollers in the bonding mechanism. In such cases, the rollers can be replaced by adjusting the mechanism based on the adhesion between the breathable membrane and the double-sided adhesive. By replacing the rollers, the diameter and pressure weight of the rollers can be increased, allowing for a tighter and smoother bond between the membrane and the double-sided adhesive during lamination, thus improving the stability of the subsequent connection between the breathable membrane and the earpiece.

[0011] Preferably, a guide block is fixedly connected to one end of the arc surface of the rotating rod, and the cross-section of the guide block is funnel-shaped.
[0012] The effect achieved by the above components is that the guide rod can increase the speed at which the rotating rod connects to the inner wall of the limiting hole.
[0013] Preferably, a plurality of auxiliary grooves are provided at the other end of the arc surface of the rotating rod, and the plurality of auxiliary grooves are evenly distributed on the rotating rod.
[0014] The effect achieved by the above components is that the auxiliary groove can increase the friction on the surface of the rotating rod.

A positioning rod is slidably passed through the other inner wall of the limiting frame. A second spring is sleeved on one end of the arc surface of the positioning rod. The two ends of the second spring are fixedly connected to the positioning rod and one side of the limiting frame, respectively. One end of the arc surface of the positioning rod is slidably passed through the inner wall of the connecting plate.
[0016] The effect achieved by the above components is as follows: the surface of the motor is relatively fragile and will malfunction when it is subjected to external impact. At this time, the auxiliary mechanism can be fixed on the motor to protect the surface of the motor and prevent the motor from directly contacting the outside world, thereby improving the service life of the motor.
[0017] Preferably, a pull ring is rotatably connected to the inner wall of the positioning rod.

[0035] In the embodiments of this utility model, please refer to Figures 2 to 6The adjusting mechanism 2 includes a mounting plate 201, which is fixedly connected to the side of two support plates 4 away from the power mechanism 6. A motor 202 is fixedly connected to one side of the mounting plate 201. A power rod 203 is fixedly connected to the output end of the motor 202. A plurality of limiting holes 207 are opened at one end of the arc surface of the power rod 203. The plurality of limiting holes 207 are evenly distributed at one end of the arc surface of the power rod 203. A roller 204 is slidably connected to the arc surface of the power rod 203. Three guide grooves 205 are opened on one inner wall of the roller 204. A plurality of guide rods 206 are slidably connected to the inner wall of the guide grooves 205. The plurality of guide rods 206 are evenly distributed on the power rod 203 and are fixedly connected to the power rod 203. Three slots 209 are provided on one side of the shaft 204. A limit rod 208 is slidably connected to the inner wall of the slot 209. One end of the arc surface of the limit rod 208 is fixedly connected to the arc surface of the power rod 203. Several fixing blocks 210 are fixedly connected to one side of the other inner wall of the roller 204. The fixing blocks 210 are evenly distributed on one side of the inner wall of the roller 204. A sliding plate 212 is slidably connected to the arc surface of the power rod 203. A slider 217 slides through the inner wall of the sliding plate 212. A pressing ring 214 is fixedly connected to one side of the slider 217. A first spring 213 is sleeved on one end of the arc surface of the sliding plate 212. The two ends of the arc surface of the first spring 213 are fixedly connected to the sliding plate 212 and the pressing ring 214, respectively. The sliding plate 212 is close to the pressing ring. Several assembly pieces 215 are fixedly connected to one side of 214. These assembly pieces 215 are evenly distributed on the sliding plate 212. The assembly pieces 215 are elastic sheets. Positioning holes 216 are opened on the side of the assembly pieces 215. A connecting rod 211 slides through the inner wall of the positioning hole 216. One end of the arc surface of the connecting rod 211 is fixedly connected to one end of the inner wall of the roller 204. A rotating rod 219 is threaded through the inner wall of the slider 217. One end of the arc surface of the rotating rod 219 is threaded through the inner wall of one of the limiting holes 207. The dustproof and waterproof breathable membrane is designed to protect the earpiece from external pollutants such as moisture and dust while maintaining the breathability of the device and ensuring that the sound quality is not affected. Generally, before attaching the breathable membrane to the earpiece, the membrane is first... The air membrane cylinder 7 is fixed to the bonding mechanism 1, and the double-sided adhesive cylinder 5 is fixed to the power mechanism 6. Under the action of the roller 204, the dustproof and waterproof breathable membrane of the breathable membrane cylinder 7 can be bonded to the double-sided adhesive on the double-sided adhesive cylinder 5 through the bonding mechanism 1. The double-sided adhesive helps to firmly adhere the breathable membrane to the earpiece, ensuring that there are no gaps between the membrane and the earpiece surface, preventing moisture and dust from entering through the membrane edges. However, during the bonding process of the double-sided adhesive and the breathable membrane through the bonding mechanism 1, it was found that the existing bonding mechanism 1 uses a small-diameter roller 204 for film coating and pressure application. After completing the above operations, in the final product breathable membrane functional testing stage, acoustic and air pressure tests frequently fail.This also leads to instability and substandard results when the breathable membrane with double-sided adhesive is processed using a small-diameter roller 204 via the lamination mechanism 1. In this case, the roller 204 can be replaced by the adjustment mechanism 2 according to the adhesion state between the breathable membrane and the double-sided adhesive. By replacing the roller 204, its diameter and pressure weight are increased, allowing for a tighter and smoother adhesion between the membrane and the double-sided adhesive during lamination. This improves the stability of the subsequent connection between the breathable membrane and the earpiece. A connecting ring 218 is fixedly connected to one side of the slider 217. The inner wall is slidably connected to the arc surface of the power rod 203. The connecting ring 218 slides on the power rod 203, which can improve the stability of the slider 217 sliding within the sliding plate 212. A guide block 221 is fixedly connected to one end of the arc surface of the rotating rod 219. The cross-section of the guide block 221 is funnel-shaped. The guide rod 206 can increase the speed at which the rotating rod 219 connects to the inner wall of the limiting hole 207. Several auxiliary grooves 220 are opened at the other end of the arc surface of the rotating rod 219. The auxiliary grooves 220 are evenly distributed on the rotating rod 219, which can increase the friction of the surface of the rotating rod 219.
[0036] In the embodiments of this utility model, please refer to Figure 7 The auxiliary mechanism 3 includes a limiting frame 31, which is fixedly connected to one side of the mounting plate 201. A connecting plate 32 is slidably connected to one inner wall of the limiting frame 31. A protective shell 33 is fixedly connected to the side of the connecting plate 32 away from the mounting plate 201. The inner wall of the protective shell 33 is slidably connected to the arc surface of the motor 202. A positioning rod 34 is slidably passed through the other inner wall of the limiting frame 31. A second spring 35 is sleeved on one end of the arc surface of the positioning rod 34. The two ends of the second spring 35 are fixedly connected to the positioning rod 34 and one side of the limiting frame 31, respectively. One end of the arc surface of the positioning rod 34 slides against the inner wall of the connecting plate 32. The surface of the motor 202 is relatively fragile and may malfunction when subjected to external impact. In this case, the auxiliary mechanism 3 can be fixed to the motor 202 to protect the surface of the motor 202 and prevent the motor 202 from directly contacting the outside world, thereby improving the service life of the motor 202. The inner wall of the positioning rod 34 is rotatably connected to the pull ring 36, which can improve the speed efficiency of pulling the positioning rod 34. The arc surface of the protective shell 33 is provided with several heat dissipation holes 37, which can dissipate the heat generated by the motor 202 during long-term operation through the protective shell 33.
[0037] The working principle of the dustproof, waterproof, and breathable membrane bonding device for earpieces provided by this utility model is as follows: When it is necessary to disassemble the roller 204, rotate the rotating rod 219 inside the slider 217 to remove the rotating rod 219 from the slider 217 and the limiting hole 207. At this time, the fixing effect of the rotating rod 219 on the slider 217 can be released. Press the sliding plate 212, and then slide the slider 217 inside the sliding plate 212. The movement of the slider 217 can drive the pressing ring 214 to move. The movement of the pressing ring 214 will drive the first spring 213 to be stretched. The movement of the pressing ring 214 will stretch several... The assembly piece 215 is compressed, and the assembly piece 215 will deform under force. At this time, the positioning hole 216 can be removed from the connecting ring 218. Then, the sliding plate 212 can be pulled to remove the assembly piece 215 from the inner wall of the roller 204. Then, the sliding plate 212 can be removed from the power rod 203. At this time, the fixing effect on the roller 204 can be released. The roller 204 can be pulled. The movement of the roller 204 will drive the limit rod 208 to be pulled out from the slot 209. The roller 204 will drive the guide groove 205 to be removed from the power rod 203 along the direction of the guide rod 206.
[0038] When roller 204 needs to be installed, connect the inner wall of the new-sized roller 204 to the power rod 203. At this time, align the angle of the guide groove 205 and the guide rod 206, and then push the roller 204. The roller 204 will move towards the motor 202 along the direction of the guide rod 206. When the inner wall of the slot 209 contacts the limit rod 208, stop pushing the roller 204. Connect the inner wall of the sliding plate 212 to the arc surface of the power rod 203. At this time, the slider 217 can be pushed. The movement of the slider 217 will drive the pressing ring 214 to move. The movement of the pressing ring 214 will drive the spring to stretch. At this time, the assembly piece 215 can be pressed by the pressing ring 214, pushing the assembly piece 215 into the inner wall of the roller 204. Connect the positioning hole 216 on the assembly piece 215 to the connecting rod. Once the rod 211 is aligned, the slider 217 can be released. The first spring 213 will reset and drive the pressing ring 214 to move away from the assembly piece 215. At this time, the positioning hole 216 on the reset assembly piece 215 can connect with the arc surface of the connecting rod 211. Pulling the slider 217 will cause the pressing ring 214 to move. The first spring 213 will be squeezed by the pressing ring 214, aligning the inner wall of the slider 217 with one of the limiting holes 207. At this time, the rotating rod 219 can be rotated inside the slider 217, so that the rotating rod 219 can connect with the limiting hole 207 through the inner wall of the slider 217. At this time, the roller 204 can be fixed on the power rod 203, and the motor 202 installed on the mounting plate 201 can be started to drive the roller 204 to work.
[0039] When it is necessary to protect the surface of the motor 202, pull the positioning rod 34. The movement of the positioning rod 34 will cause the second spring 35 to stretch. At this time, the protective shell 33 and the connecting plate 32 can be placed in the limiting frame 31. Align the inner wall of the connecting plate 32 with the position of the positioning rod 34. Then, release the positioning rod 34. The second spring 35 will return to its original position and drive the positioning rod 34 to connect with the inner wall of the connecting plate 32 through the limiting frame 31. At this time, the connecting plate 32 can be fixed in the limiting frame 31, and the motor 202 can be protected by the protective shell 33.
