Description

Technical Field

[0001] The utility model relates to the technical field of loudspeaker manufacturing, in particular to a loudspeaker dust cap adsorption and installation device. Background Art

[0002] With the booming automotive industry, consumers' demands for car audio quality are constantly increasing. As a key component of car audio systems, the quality and performance of car speakers directly impact the user's listening experience. Dust caps play a vital role in protecting the voice coil and preventing dust intrusion. Efficient and accurate dust cap installation during production is crucial to ensuring speaker quality. Traditional dust cap installation methods are mostly manual, which can easily cause contamination and damage. For example, due to human contact and uncertain operating environments, dust caps can become contaminated by dust, grease, and other substances, or be squeezed and deformed during installation, reducing product quality. Furthermore, manual installation is inefficient. Utility Model Content

[0003] In view of this, an object of the present invention is to provide a speaker dust cap adsorption and installation device to solve the above-mentioned problems.

[0004] In order to achieve the above objectives, the present invention provides the following technical solutions:

[0005] The utility model provides a speaker dust cap adsorption and installation device, including an adsorption handle, a micro vacuum pump, a solenoid valve, a vacuum suction cup, an electric control box and a start-stop switch. The adsorption handle is respectively provided with a micro vacuum pump installation cavity and a solenoid valve installation cavity. The micro vacuum pump and the solenoid valve are respectively installed in the micro vacuum pump installation cavity and the solenoid valve installation cavity inside the adsorption handle.

[0006] The speaker dust cap adsorption and installation device of the present invention uses a micro vacuum pump to extract air from a vacuum suction cup, generating negative pressure in the vacuum cup to form an adsorption force, thereby adsorbing the speaker dust cap. After the speaker dust cap is installed on the speaker, the vacuum is quickly released by opening the solenoid valve to desorb the speaker dust cap. The use of the vacuum suction cup replaces manual contact, thus not only avoiding contamination and damage to the dust cap caused by manual operation, but also avoiding product quality defects caused by manual squeezing and deformation of the dust cap, while effectively improving installation efficiency. In addition, the micro vacuum pump and solenoid valve are disposed within the adsorption handle, thereby achieving a compact and miniaturized structure of the speaker dust cap adsorption and installation device, thereby improving the practicality of the device.

The air inlet filter adopts a two-layer filter structure, including an outer coarse filter and an inner fine filter. The outer coarse filter is used to intercept larger particles, and the inner fine filter is used to filter fine dust. This can effectively prevent dust and debris from entering the pump, protect the internal components of the pump, and extend its service life.

[0008] Preferably, a vacuum pressure gauge is provided between the micro vacuum pump and the vacuum suction cup, and a display window of the vacuum pressure gauge is provided on the surface of the suction handle. Through the vacuum pressure gauge, the operator can intuitively read the vacuum level of the vacuum suction cup.

[0009] Preferably, an electronic pressure switch is provided between the micro vacuum pump and the vacuum cup, the electronic pressure switch being disposed within the suction handle and electrically connected to the electrical control box.

[0010] Preferably, the adsorption handle is made of high-strength, lightweight engineering plastic injection molding, and the high-strength, lightweight engineering plastic injection molding is ABS plastic or polycarbonate plastic.

[0011] Preferably, the surface of the suction handle is also provided with an anti-slip design, which can be an integrally formed anti-slip texture or an anti-slip rubber cover, etc., as long as it can achieve the anti-slip purpose. The anti-slip design of the suction handle surface can further improve the comfort and stability of operation.

[0012] Preferably, a heat dissipation hole is further provided on the suction handle at a position corresponding to the micro vacuum pump installation cavity. Through the provision of the heat dissipation hole, the heat energy generated by the operation of the micro vacuum pump can be dissipated, thereby increasing the service life of the micro vacuum pump.

[0013] Preferably, the adsorption handle is further provided with a hook to facilitate fixing the device on other equipment or a workbench.

[0014] Beneficial Effects: The speaker dust cap adsorption and installation device of the present invention uses a micro vacuum pump to extract air from a vacuum suction cup, generating negative pressure in the vacuum cup to form an adsorption force, thereby adsorbing the speaker dust cap. After the speaker dust cap is installed on the speaker, the vacuum is quickly released by opening the solenoid valve to desorb the speaker dust cap. The use of the vacuum suction cup replaces manual contact, thus avoiding contamination and damage to the dust cap caused by manual operation and product quality defects caused by manual squeezing and deformation of the dust cap. At the same time, it effectively improves installation efficiency. In addition, the micro vacuum pump and solenoid valve are arranged inside the adsorption handle, which further achieves a compact and miniaturized structure of the speaker dust cap adsorption and installation device, thereby improving the practicality of the device.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-3As shown, the utility model provides a speaker dust cap adsorption and installation device, including an adsorption handle 3, a micro vacuum pump 6, a solenoid valve 12, a vacuum suction cup 2, an electric control box 1 and a start-stop switch 5. The adsorption handle 3 is respectively provided with a micro vacuum pump installation cavity 14 and a solenoid valve installation cavity 13. The micro vacuum pump 6 and the solenoid valve 12 are respectively installed in the micro vacuum pump installation cavity 14 and the solenoid valve installation cavity 13 inside the adsorption handle. The front end of the adsorption handle 3 is provided with a suction cup seat 4, the vacuum suction cup 2 is installed on the suction cup seat 4, the air inlet end of the micro vacuum pump 6 and the vacuum suction cup 2 are connected through a connecting pipe, the solenoid valve 12 is provided at the air outlet end of the micro vacuum pump 6, and the exhaust end of the solenoid valve 12 is connected to the atmosphere through the exhaust hole 11, the start-stop switch 5 is provided on the surface of the adsorption handle 3, the micro vacuum pump 6 and the solenoid valve 12 are respectively electrically connected to the electric control box 1, and the start-stop switch 5 is connected to the electric control box.

[0021] The working principle of the present invention is as follows: when the vacuum pump 6 is started, it begins to draw air from the vacuum cup 2, creating a negative pressure inside the cup, which generates a suction force and adheres to the dust cap. At this time, the solenoid valve 12 is closed, and the gas drawn by the vacuum pump 6 cannot be discharged from the outlet. As a result, a certain pressure gradually accumulates in the pipe between the vacuum pump 6 and the solenoid valve 12. When the dust cap is installed on the speaker and the suction cup 2 needs to be released, the solenoid valve 12 is opened, and the gas originally accumulated in the pipe is quickly discharged into the atmosphere through the solenoid valve 12. This quickly reduces the pressure difference between the suction cup and the outside atmosphere, causing the suction force to disappear, thereby achieving a rapid release of the vacuum cup 2. By controlling the opening and closing of the solenoid valve 12, the suction and release time of the vacuum cup 2 can be precisely controlled. Because the solenoid valve 12 can quickly discharge the gas from the outlet of the vacuum pump 6, the release process of the vacuum cup 2 is very fast. Compared with some methods that rely on natural leakage to release the suction, the time of each working cycle is greatly shortened, thereby improving overall work efficiency.

[0022] In some embodiments, the air inlet end of the micro vacuum pump 6 is also provided with an air inlet filter 9. The air inlet filter 9 adopts a two-layer filter structure, including an outer coarse filter and an inner fine filter. The outer coarse filter is used to intercept larger particles, and the inner fine filter is used to filter tiny dust. It can effectively prevent dust, debris, etc. from entering the pump, protect the internal components of the pump, and extend its service life.

[0023] In some embodiments, a vacuum pressure gauge 7 is further provided between the micro vacuum pump 6 and the vacuum suction cup 2, and a display window of the vacuum pressure gauge 7 is provided on the surface of the suction handle 3. Through the vacuum pressure gauge 7, the operator can intuitively read the vacuum level of the vacuum suction cup 2.

[0024] In some embodiments, an electronic pressure switch 8 is further provided between the micro vacuum pump 6 and the vacuum cup 2. The electronic pressure switch 8 is disposed within the suction handle 3 and is electrically connected to the electrical control box 1. The electronic pressure switch 8 allows for more precise control of the vacuum degree of the vacuum cup.

[0025] In some embodiments, the suction handle 3 is injection-molded from a high-strength, lightweight engineering plastic, such as ABS plastic or polycarbonate plastic. The suction handle is injection-molded from a high-strength, lightweight engineering plastic, such as ABS plastic or polycarbonate plastic, to ensure structural strength while also reducing weight, thereby improving the performance of the device.

[0026] In some embodiments, the surface of the suction handle 3 is also provided with an anti-slip design. The anti-slip design can be an integrally formed anti-slip texture or an anti-slip rubber cover, as long as it can achieve the anti-slip purpose. The anti-slip design of the suction handle surface can further improve the comfort and stability of operation.

[0027] In some embodiments, a heat dissipation hole 10 is further provided on the suction handle 3 at a position corresponding to the micro vacuum pump installation cavity. Through the provision of the heat dissipation hole 10, the heat energy generated by the micro vacuum pump 6 can be dissipated, thereby increasing the service life of the micro vacuum pump.

[0028] In some embodiments, the suction handle 3 is further provided with a hook to facilitate fixing the device on other equipment or a workbench.
