Description

Technical Field

[0001] This utility model relates to the technical field of walkie-talkie production equipment, specifically a device for bonding waterproof membranes for walkie-talkies. Background Technology

[0002] A walkie-talkie, also known as a two-way radio, is a portable device that enables two-way communication. It uses the propagation of radio signals in the air to achieve point-to-point or point-to-multipoint communication. Walkie-talkies do not require any external network support to make calls, and there are no call charges. They are suitable for relatively fixed and frequent communication situations.

[0003] Existing waterproof membrane bonding devices for walkie-talkies lack a heating system to assist bonding. This can lead to the membrane's edges or minor unevenness not adhering completely to the outer shell. Furthermore, when bonding the waterproof membrane at room temperature, its poor plasticity allows air to easily become trapped between the membrane and the walkie-talkie shell. This trapped air is difficult to expel naturally because without heating to soften the membrane, it doesn't naturally adjust its shape under pressure to expel the air. These residual air bubbles form voids under the waterproof membrane, compromising its integrity. Additionally, under external pressure, these bubbles may rupture, causing the surrounding waterproof membrane to separate from the shell, further reducing its waterproofing effectiveness.

[0004] Therefore, a device for bonding waterproof membranes for walkie-talkies is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this paper solves the problem of the lack of a heating system to assist in bonding. This would result in the membrane's edges or minor unevenness not being able to fully adhere to the outer shell. Additionally, when bonding the waterproof membrane at room temperature, the poor plasticity of the membrane makes it easy for air to become trapped between the waterproof membrane and the walkie-talkie shell. Moreover, this trapped air is difficult to expel naturally because without heating to soften the membrane, it will not naturally adjust its shape under pressure to expel the air. These residual air bubbles will form voids under the waterproof membrane, compromising its integrity. Furthermore, under external pressure, these bubbles may rupture, causing the surrounding waterproof membrane to separate from the outer shell, further reducing the waterproof effect.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The waterproof membrane bonding device for walkie-talkies of this utility model includes a membrane bonding control panel. A walkie-talkie clamping assembly is installed on the top of the membrane bonding control panel, and a heating control assembly is connected to the top of the walkie-talkie clamping assembly. A tension adjustment assembly is provided on the side of the membrane bonding control panel. The heating control assembly includes a worm gear. A crank is fixedly connected to the end of the worm gear, and a worm wheel is meshed on the top of the worm gear. A control gear is fixedly connected to the side of the worm wheel. A lifting rod is meshed on the outer wall of the control gear, and a heating block is installed at the bottom of the lifting rod.

[0007] Preferably, the heating block forms a lifting structure with the walkie-talkie clamping assembly via a lifting rod, and the lifting rod meshes with the control gear, and the worm gear meshes with the worm.

[0008] Preferably, the walkie-talkie clamping assembly includes a motor, a clamping gear is fixedly connected to the output end of the motor, a first control lever is engaged on one side of the clamping gear, a first clamping block is fixedly connected to the top of the first control lever, a second control lever is engaged on the other side of the clamping gear, and a second clamping block is fixedly connected to the top of the second control lever.

[0009] Preferably, the second clamping block forms a sliding structure with the first clamping block through the second control rod, and the first clamping block forms a sliding structure with the second clamping block through the first control rod, and both the first control rod and the second control rod mesh with the clamping gear.

[0010] Preferably, the tension adjustment assembly includes a mounting frame, a fixed roller is rotatably connected inside the mounting frame, a spring is fixedly connected to the side of the mounting frame, an elastic block is fixedly connected to the top of the spring, and an adjustment roller is rotatably connected to the side of the elastic block.

[0011] Preferably, there are two fixed rollers symmetrically arranged about the central axis of the adjusting roller, and the adjusting rollers are elastically connected to the mounting frame by springs.

[0012] The advantages of this utility model are:

[0013] 1. This utility model is equipped with a heating control component. The heating block can preheat the bonding part, so that the waterproof membrane softens when heated during the bonding process, making it easier to bond tightly to the walkie-talkie shell and reducing the generation of air bubbles. The heating block can be pressed vertically downward by turning the handle, so that the waterproof membrane can be tightly bonded to the walkie-talkie shell.

[0014] 2. This utility model is equipped with a walkie-talkie clamping assembly. Driven by a motor, the first clamping block and the second clamping block clamp and fix the walkie-talkie. It can adapt to different widths of walkie-talkies and clamp them accordingly, thereby effectively preventing damage to the walkie-talkie shell due to excessive clamping or displacement of the walkie-talkie during the waterproof membrane bonding process due to excessive clamping, thus affecting the bonding quality.

[0015] 3. This utility model is equipped with a tension adjustment component. When the waterproof membrane tension is too tight, the elastic block will squeeze the spring. When the waterproof membrane tension is too loose, the adjustment roller will slide upward under the elastic force of the spring, which can effectively tighten the waterproof membrane and restore the tension to a suitable range, thereby maintaining the tension stability of the waterproof membrane during the conveying process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, this embodiment includes a film application control panel 1, a walkie-talkie clamping assembly 2, a heating control assembly 3, and a tension adjustment assembly 4.

[0025] The top of the film application control panel 1 is equipped with a walkie-talkie clamping component 2, and the top of the walkie-talkie clamping component 2 is connected to a heating control component 3. Furthermore, a tension adjustment component 4 is provided on the side of the film application control panel 1.

[0026] The heating control assembly 3 includes a worm gear 301, a crank handle 302, a worm wheel 303, a control gear 304, a lifting rod 305, and a heating block 306.

[0027] The worm gear 301 is arranged horizontally, and a crank 302 is fixedly connected to the end of the worm gear 301. A worm wheel 303 is engaged at the top of the worm gear 301, and a control gear 304 is fixedly connected to the side of the worm wheel 303. A lifting rod 305 is engaged on the outer wall of the control gear 304, and a heating block 306 is installed at the bottom of the lifting rod 305. The heating control component 3 presses down the heating block 306 by rotating the rocker handle 302, causing the waterproof membrane to soften due to heat. This facilitates a tight fit with the walkie-talkie casing and reduces air bubbles. The heating block 306 forms a lifting structure with the walkie-talkie clamping component 2 via the lifting rod 305. The lifting rod 305 meshes with the control gear 304, and the worm gear 303 meshes with the worm 301. The heating block 306 can preheat the bonding area, causing the waterproof membrane to soften during the bonding process, making it easier to fit tightly with the walkie-talkie casing and reducing air bubbles. The heating block 306 can be pressed down vertically by rotating the rocker handle 302, thus ensuring a tight fit of the waterproof membrane onto the walkie-talkie casing.

[0028] like Figure 1 and Figure 3 As shown, the walkie-talkie clamping assembly 2 includes a motor 201, a clamping gear 202, a first control lever 203, a first clamping block 204, a second control lever 205, and a second clamping block 206.

[0029] In this embodiment, a clamping gear 202 is fixedly connected to the output end of the motor 201. The clamping gear 202 is arranged in a horizontal direction, and a first control rod 203 is engaged on one side of the clamping gear 202. A first clamping block 204 is fixedly connected to the top of the first control rod 203. A second control rod 205 is engaged on the other side of the clamping gear 202, and a second clamping block 206 is fixedly connected to the top of the second control rod 205. In this embodiment, the walkie-talkie clamping assembly 2, driven by the motor 201, can stably clamp walkie-talkies of different widths via the first clamping block 204 and the second clamping block 206, preventing damage to the casing or displacement during bonding that could affect quality. The second clamping block 206 forms a sliding structure with the first clamping block 204 via the second control rod 205, and the first clamping block 204 forms a sliding structure with the second clamping block 206 via the first control rod 203. Both the first control rod 203 and the second control rod 205 mesh with the clamping gear 202. Driven by the motor 201, the first clamping block 204 and the second clamping block 206 clamp and fix the walkie-talkie, adapting to different widths of walkie-talkies. This effectively prevents damage to the walkie-talkie casing due to excessive clamping or displacement of the walkie-talkie during waterproof membrane bonding due to excessive clamping, thus affecting bonding quality.

[0030] like Figure 1 and Figure 4 As shown, the tension adjustment assembly 4 includes a mounting frame 401, a fixed roller 402, a spring 403, an elastic block 404, and an adjustment roller 405.

[0031] In this embodiment, the mounting bracket 401 is fixedly mounted on the top side of the film application control panel 1. A fixed roller 402 is rotatably connected inside the mounting bracket 401, and a spring 403 is fixedly connected to the side of the mounting bracket 401. An elastic block 404 is fixedly connected to the top of the spring 403, and an adjusting roller 405 is rotatably connected to the side of the elastic block 404.

[0032] The tension adjustment component 4 automatically adjusts the tension of the waterproof membrane when the tension changes due to the elastic action of the spring 403, maintaining a stable tension during conveying. There are two fixed rollers 402 symmetrically arranged about the central axis of the adjusting roller 405, and the adjusting roller 405 forms an elastic structure with the mounting frame 401 through the spring 403. When the tension of the waterproof membrane is too tight, the elastic block 404 will squeeze the spring 403. When the tension of the waterproof membrane is too loose, the adjusting roller 405 will slide upward under the elastic force of the spring 403, which can effectively tighten the waterproof membrane and restore the tension to a suitable range, thereby maintaining the tension stability of the waterproof membrane during the conveying process.

[0033] The working principle of this embodiment is as follows: First, the walkie-talkie is placed on the side of the first clamping block 204. Then, the switch of the motor 201 is turned on. The motor 201 will drive the clamping gear 202 to rotate. Since the clamping gear 202 is meshed with the first control rod 203 and the second control rod 205 on the side, the rotating clamping gear 202 will cause the first control rod 203 to drive the first clamping block 204 to slide towards the middle. The second control rod 205 will drive the second clamping block 206 to slide towards the middle as well. At this time, the first clamping block 204 and the second clamping block 206 will clamp the walkie-talkie according to its width. Next, the waterproof membrane is passed around the bottom of the fixed roller 402 and around the top of the adjusting roller 405. The waterproof membrane is then wrapped around the adjusting roller 405. Then, the waterproof membrane is passed around the bottom of another fixed roller 402 and placed on the top of the walkie-talkie.

[0034] Next, when the waterproof membrane is placed on top of the walkie-talkie, if the membrane tension is too tight, the pressure on the elastic block 404 increases, causing the elastic block 404 to compress the spring 403. If the membrane tension is too loose, the elastic force of the spring 403 will push the adjusting roller 405 upward, effectively tightening the membrane and restoring the tension to a suitable range. This maintains the stability of the membrane tension during transport. Finally, the crank handle 302 can be turned, driving the worm gear 301 to rotate. Due to the side engagement of the worm gear 301... There is a worm gear 303. The rotating worm 301 will cause the worm gear 303 to rotate, and the worm gear 303 will cause the rotating rod inside the worm gear 303 to rotate. The rotating rod will cause the control gear 304 to rotate. Since the control gear 304 is meshed with the lifting rod 305 on its side, the control gear 304 will drive the heating block 306 to slide downward through the lifting rod 305. This will allow the heating block 306 to preheat the bonding part, so that the waterproof membrane softens due to heat during the bonding process, making it easier to bond tightly with the walkie-talkie shell and reducing the generation of air bubbles.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
