Abstract
Description
Technical Field
[0001] The utility model relates to the field of loudspeaker production equipment, in particular to a magnet cleaning structure of an automatic loudspeaker production line. Background Art
[0002] Currently, the main function of the magnet in a speaker is to generate a magnetic field and interact with the coil, causing the coil to vibrate and output the vibrations as sound. There are two types of speaker magnets: permanent magnets and electromagnets. Permanent magnets are made of permanent magnetic material and can generate a relatively stable magnetic field with high sensitivity and precision. However, during the current speaker production process, permanent magnets are prone to dust accumulation on their surfaces. Traditional dust removal methods rely on air pressure, but this method can easily blow dust into other equipment on the production line, potentially reducing the sensitivity of other equipment or causing electrical failures. Utility Model Content

[0010] Preferably, the top of the first pipeline is also connected to a control valve via a hose, and the control valve is connected to an air intake pump.
[0011] Preferably, each magnet placement hole on the stage is connected by a microchannel, and a straight slot is provided in the middle of each microchannel.
[0012] Principle of this utility model:
[0013] The utility model is arranged on an automatic production line of a loudspeaker. The magnet is transported to one side of the utility model through a conveyor belt. When the magnet reaches a designated position, the controller enables the first electric cylinder to move the cleaning mechanism along the guide arm direction to the upper part of the conveyor belt, and then enables the second cross plate to drive the second pipe to move downward through the second electric cylinder. At this time, the adsorption nozzle reaches the upper part of the magnet, and then the controller enables the control valve to open, and the magnet is sucked up by negative pressure, and then moved to the upper part of the loading platform. In this process, the cleaning mechanism is equivalent to transportation. When the position of the magnet is opposite to the magnet placement hole, the control valve is closed, and the sucked magnet is placed in the magnet placement hole. At this time, the controller opens the control valve, and air is blown out from the adsorption nozzle to clean the dust on the surface. At the same time, the negative pressure suction pipe also starts to pump air outward, and the dust at the bottom of the magnet is adsorbed by the negative pressure suction pipe. The suction pressure in this process is much greater than the blowing pressure. In this way, the dust blown from the upper part of the magnet is sucked out from the negative pressure suction pipe through the straight slot, so that the dust on both sides of the magnet can be cleaned at the same time, and this process avoids the dust affecting the sensitivity of other equipment.
[0014] The beneficial effects of the present invention are:
[0015] The moving mechanism has a simple structure and is easy to operate. Secondly, the cleaning mechanism can not only clean the magnets, but also transport the magnets. During the transportation process, the suction nozzle mainly plays an adsorption role, and cleans the front and back sides of the magnets placed in the magnet placement holes through the stage. At this time, the suction nozzle blows air to clean the dust on the upper part of the magnet, and the bottom of the magnet is sucked out through the negative pressure suction pipe. The dust is cleaned on both sides at the same time, and the suction pressure is much greater than the blowing pressure. This not only cleans the magnets, but also avoids the impact of dust on other surrounding equipment, thereby improving work efficiency and equipment service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example 1:
[0025] Reference Figure 1-6 The upper part of the support column 1 is provided with a guide arm 2, and the transfer cleaning mechanism 3 is equipped on the guide arm 2. The upper part of the support column 1 is provided with a guide arm 2, and the transfer cleaning mechanism 3 is equipped on the guide arm 2. The upper part of the fixed seat 7 and the support plate 8 are fixedly connected to the bottom of the loading platform 4. The loading platform 4 is located below the transfer cleaning mechanism 3. The loading platform 4 is a hollow structure, and a plurality of magnet placement holes 5 are provided on the loading platform 4. The loading platform 4 is hollow, and one end of the negative pressure suction pipe 6 is connected to the inside. One side of the loading platform 4 is also connected to an external air pump through the negative pressure suction pipe 6. During the dust cleaning process, the pressure of the negative pressure suction pipe 6 is much greater than the pressure of the air blown by the adsorption nozzle 326.
[0026] The support column 1 is also fixed with oblique support arms 9 on both sides, and a stabilizing seat 10 is provided on the upper part of the oblique support arm 9. The stabilizing seat 10 mainly serves to fix the guide arm 2. The guide arm 2 is fixedly installed on the two stabilizing seats 10, and a guide groove 11 is also provided in the middle of the guide arm 2.
[0027] The loading platform 4 also has several connecting holes 12, each of which is equipped with a connecting screw 13, and the connecting screw 13 is fixedly connected to the support plate 8, which provides higher stability and ensures that the loading platform 5 will not tilt or shake after the magnet is placed.
[0028] The transfer and cleaning mechanism 3 includes a moving mechanism 31 and a cleaning mechanism 32. The moving mechanism 31 includes a first electric cylinder 310, a moving plate 311, a vertical plate 312 and a connecting groove 313. The first electric cylinder 310 is fixedly installed on one side of the guide arm 2. One end of the moving plate 311 extends into the guide groove 11. The other end of the moving plate 311 is fixedly connected to the vertical plate 312. The other side of the vertical plate 312 is also equipped with a cleaning mechanism 32. The vertical plate 312 is also provided with a connecting groove 313 on the side close to the cleaning mechanism 32. The moving process is mainly achieved by the extension and retraction of the first electric cylinder 310 to make the moving plate 311 move left and right along the guide arm 2.
[0029] The cleaning mechanism 32 includes a first transverse plate 320, a second transverse plate 321, a limit block 322, a first pipe 323, a second pipe 324, a return spring 325, a suction nozzle 326, a second electric cylinder 327 and an ear seat 328. One end of the first transverse plate 320 is fixedly connected to the vertical plate 312. The second transverse plate 321 is located below the first transverse plate 320, and one end of the second transverse plate 321 is fixed with the limit block 322. The limit block 322 is located in the connecting groove 313. A plurality of first pipes 323 are provided on the first transverse plate 320, and a plurality of second pipes 324 corresponding to the first pipes 323 are provided on the second transverse plate 321. The bottom part of the first pipe 323 extends into the second pipe 324, and the first A return spring 325 is also installed between the pipe 323 and the second pipe 324. The return spring 325 is fixedly connected to the first pipe 323 and the second pipe 324 respectively. When the second cross plate 321 moves downward, the second pipe 324 also moves downward. The second pipe 324 is mounted on the first pipe 323, and the upper part of the second pipe 324 is limited, so it will not detach during the downward movement and will not affect the airflow. When moving upward, the return spring 325 and the second electric cylinder 327 work simultaneously. A suction nozzle 326 is provided at the bottom of the second pipe 324, a second electric cylinder 327 is also provided on the first cross plate 320, and an ear seat 328 is also provided on the second cross plate 321, and the telescopic end of the second electric cylinder 327 is fixedly connected to the ear seat 328.
[0030] Transfer cleaning principle:
[0031] When the magnet reaches the designated position, the controller causes the first electric cylinder 310 to move the cleaning mechanism 32 along the guide arm 2 to the upper part of the conveyor belt, and then causes the second cross plate 321 to drive the second pipe 324 downward through the second electric cylinder 327. At this time, the adsorption nozzle 326 reaches the upper part of the magnet, and then the controller causes the control valve to open, and the magnet is sucked up by negative pressure, and then moved to the upper part of the loading platform 4. In this process, the cleaning mechanism 32 plays a transport role. When the magnet position is opposite to the magnet placement hole 5, the control valve is closed, and the sucked magnet is placed in the magnet placement hole 5. At this time, the controller opens the control valve, and air is blown out from the adsorption nozzle 326 to clean the dust on the upper surface of the magnet. At the same time, the negative pressure suction pipe 6 also starts to pump air outward, and the dust at the bottom of the magnet is adsorbed by the negative pressure suction pipe 6. The suction pressure in this process is much greater than the blowing pressure. In this way, the dust blown from the upper part of the magnet is sucked out from the negative pressure suction pipe 6 through the straight slot 16, so that the dust on both sides of the magnet can be cleaned at the same time.
[0032] The top of the first pipe 323 is also connected to a control valve via a hose 14 , and the control valve is connected to an air intake pump.
[0033] Each magnet placement hole 5 on the loading platform 4 is also connected by a microchannel 15, and a straight slot 16 is opened in the middle of each microchannel 15. The straight slot 16 is mainly used to collect the dust cleaned from the upper part inside the loading platform 4, so that it can be directly sucked out through the negative pressure suction pipe 6.
[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
