Description

Technical Field

[0001] This application relates to the technical field of speaker end cap processing, and in particular to a photosensitive ink removal device for etching miniature speaker end caps. Background Technology

[0002] The end cap of a loudspeaker is generally made of aluminum, and its surface has several small micropores. The processing of these micropores requires an etching process. After etching, the photosensitive ink on the surface of the aluminum plate needs to be removed.

[0003] In existing technology, aluminum plates are generally soaked in a sodium hydroxide solution to remove the etched ink coating, and then rinsed clean with cold water. This process is usually done manually by workers, which is inefficient. In addition, during the soaking process, the aluminum plates need to be shaken manually to improve the peeling efficiency of the ink coating, which makes the labor intensity of the workers quite high. Utility Model Content

[0004] The purpose of this application is to provide a photosensitive ink removal device for etching the end cap of a miniature speaker, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides a photosensitive ink removal device for etching the end cap of a miniature loudspeaker, employing the following technical solution:

[0006] A photosensitive ink removal device for etching the end cap of a miniature speaker includes a basket, an immersion mechanism, and a rinsing mechanism disposed next to the immersion mechanism. The immersion mechanism includes an immersion tank, a rack and pinion mechanism, a waterproof geared motor, a guide rail, a slide rail, a base, and a mounting base. The rack and pinion mechanism, the guide rail, and the slide rail are all installed at the bottom of the immersion tank along the length direction of the immersion tank. The base is slidably connected to the slide rail. The waterproof geared motor is mounted on the base. A gear that meshes with the rack and pinion mechanism is fixed to the end of the output shaft of the waterproof geared motor. The mounting base is rotatably connected to the base. A guide rod is rotatably connected to one bottom side of the mounting base. The guide rod can move along the guide rail. The cross-sectional structure of the guide rail is wavy. A lifting platform is fixed to the top of the mounting base. A positioning plate is fixed to the top of the lifting platform. Positioning rods are fixed to the four corners of the top of the positioning plate. Positioning holes are opened at the four corners of the bottom of the basket.

[0007] The flushing mechanism includes a water collection tank, and several nozzles are uniformly fixed on one inner wall of the water collection tank.

[0008] The basket has several slots evenly spaced inside, and the basket has a frame structure.

[0009] Preferably, in order to achieve automated production, a feeding robot is provided at the feeding end of the soaking mechanism, and a discharging robot is provided next to the water collection tank. The discharging robot is used to clamp the basket in the soaking mechanism and transfer it to the water collection tank for rinsing.

[0010] Preferably, in order to cooperate with the robot, the side of the basket is fixed with a connecting block for clamping by the loading robot and the unloading robot.

[0011] The bottom of the water collection tank is equipped with a drainage trough, and a filter screen is installed inside the drainage trough.

[0012] In summary, this application includes at least one of the following beneficial technical effects: During the immersion process, the entire basket of the photosensitive ink removal device for etching the end cap of the miniature speaker can perform a wave-like motion, thereby causing the aluminum plate to swing left and right in the solution. On the one hand, the left and right swing of the aluminum plate can stir the solution to generate turbulence, thereby making the solubility distribution of the sodium hydroxide aqueous solution uniform. On the other hand, it can accelerate the removal of the ink skin, greatly improve the ink removal efficiency, and also reduce the labor intensity of the workers. Attached Figure Description

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0017] This application discloses a photosensitive ink removal device for etching end caps of miniature loudspeakers, referring to... Figure 1-2The system includes a basket 1, an immersion mechanism, and a rinsing mechanism located next to the immersion mechanism. The immersion mechanism includes an immersion tank 2, a rack 21, a waterproof geared motor 22, a guide rail 23, a slide rail 24, a base 25, and a mounting seat 26. The rack 21, guide rail 23, and slide rail 24 are all installed at the bottom of the immersion tank 2 along the length of the immersion tank 2. The base 25 is slidably connected to the slide rail 24. The waterproof geared motor 22 is installed on the base 25. The output shaft end of the waterproof geared motor 22 is fixed with a gear 221 that meshes with the rack 21. The mounting seat 26 is rotatably connected to the base 25. A guide rod 261 is rotatably connected to one side of the bottom of the mounting seat 26. The guide rod 261 can move along the guide rail 23. The cross-sectional structure of the guide rail 23 is wavy. A lifting platform 27 is fixed to the top of the mounting seat 26. A positioning plate 28 is fixed to the top of the lifting platform 27. Positioning rods 281 are fixed to the four corners of the top of the positioning plate 28. Positioning holes are opened at the four corners of the bottom of the basket 1.

[0018] The rinsing mechanism includes a water collection tank 3, with several nozzles 4 evenly fixed on one side of the inner wall of the water collection tank 3, and a drainage trough at the bottom of the water collection tank 3, with a filter screen installed inside the drainage trough.

[0019] Reference Figure 2 In order to ensure that the aluminum plate is in full contact with the solution, several slots are evenly provided inside the basket 1, and the basket 1 is a frame structure.

[0020] Reference Figure 1-2 In order to achieve automated production, a feeding robot 5 is set at the feeding end of the soaking mechanism, and a discharging robot 6 is set next to the water collection tank 3. The discharging robot 6 is used to clamp the basket 1 in the soaking mechanism and transfer it to the water collection tank 3 for rinsing.

[0021] The implementation principle of the photosensitive ink removal device for etching the end cap of a miniature speaker according to an embodiment of this application is as follows:

[0022] In use, the aluminum plates for which the photosensitive ink needs to be removed are placed in the slots of the basket 1 in sequence. Then, the positioning holes at the four corners of the bottom of the basket 1 are aligned with the positioning rods 281 and installed on the positioning plate 28. The lifting platform 27 descends, causing the aluminum plates to be immersed in the sodium hydroxide aqueous solution. Then, the waterproof reduction motor 22 works and drives the base 25 to move to the right through the rack 21. During this process, when the guide rod 261 at the bottom of the mounting base 26 passes through the corrugated guide rail 23, it can cause the mounting base 26 to swing left and right, thereby causing the aluminum plates to swing left and right in the solution. On the one hand, the left and right swing of the aluminum plates can stir the solution to generate turbulence, thereby making the solubility distribution of the sodium hydroxide aqueous solution uniform. On the other hand, it can accelerate the removal of ink skin and greatly improve the ink removal efficiency.

[0023] After soaking, the staff transferred the basket 1 to the water collection tank 3. The nozzles 4 in the water collection tank 3 rinsed the aluminum plate, which could wash away the remaining loose skin.

[0024] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
