Description

Technical Field

[0001] The invention relates to the technical field of etching processing, in particular to a double-sided etching method for an aluminum automobile speaker grille. Background Art

[0002] As an important part of the car audio system, the surface treatment process of aluminum car speaker grille is not only related to the aesthetics of the product, but also directly affects its performance and durability. Etching is a technology that removes the unwanted parts of the metal surface through chemical or physical methods, leaving the desired pattern or text. In the production of car speaker grille, the etching process can accurately transfer the designed mesh pattern to the metal substrate to form a unique and complex structure.

[0003] The aluminum car horn grille is cleaned, coated with photosensitive ink, placed on both sides of the film, exposed and developed, so that the hardened ink can be attached to the outside of the aluminum car horn grille, and the aluminum car horn grille with the hardened ink pattern can be placed in the etching machine for etching. The etching machine can spray the etchant on the sheet, and the etchant can be in contact with the sheet to achieve chemical etching. The part protected by the ink will not be etched, so that the aluminum car horn grille can generate the required pattern. Finally, the ink can be removed by the de-inking machine to complete the processing. If the existing etching machine sprays the aluminum car horn grille on a single side, In order to further improve the etching efficiency of the aluminum car horn mesh, a double-sided etching method for the aluminum car horn mesh is proposed. The aluminum car horn mesh can be turned over within a certain time, so that the aluminum car horn mesh with a curved surface structure can be etched on both sides in turn, thereby effectively improving the processing efficiency and processing accuracy, and ensuring that the etchant is in full contact with the aluminum car horn mesh. Summary of the invention

[0005] The solution of the present invention to solve the above technical problems is as follows: a method for double-sided etching of an aluminum automobile horn mesh, comprising an etching box, a conveyor, and an aluminum automobile horn mesh, wherein the conveyor is installed in the etching box, an etching agent box and a water pump are fixedly installed on the top of the etching box, a drainage pipe is fixedly installed on the inner wall of the etching box, and a spray head is evenly fixedly connected to the bottom of the drainage pipe, one end of the water pump is connected to the etching agent box, and the other end is connected to the drainage pipe, the conveyor is provided with a conveyor belt, and a load-bearing bracket is evenly fixedly installed on the outer wall of the conveyor belt, the load-bearing bracket is rotatably connected to an etching frame, and both sides of the etching frame are rotatably connected to anti-dropping mesh covers, the load-bearing bracket is fixedly connected to a motor box, the motor box is fixedly connected to a laser receiver and a brake stepping motor, the conveyor is fixedly installed with a laser transmitter, the aluminum automobile horn mesh is placed in the etching frame, the etching box is fixedly connected to a discharge valve, and the discharge valve is fixedly connected to a discharge pipe;

[0006] The etching method comprises the following steps:

[0007] S1: Open the anti-separation cover of the etching frame at the right end and place the aluminum car horn mesh covered with hardened ink in the etching frame for loading. The conveyor belt in the conveyor can load the aluminum car horn mesh in the etching frame;

[0008] S2: Starting the water pump can pump the etchant in the etchant box into the drain pipe, and the etchant can be sprayed out through the spray head at the bottom of the drain pipe, so as to perform etching processing on one side of the aluminum car horn grille in the etching frame. When the etching frame moves to the middle of the conveyor, the laser receiver of the motor box can receive the laser emitted by the laser transmitter. The laser receiver can send a signal to the brake stepper motor after receiving the laser. The brake stepper motor can drive the etching frame and the aluminum car horn grille inside it to flip 180 degrees after receiving the signal, so that the spray head can spray the etchant on the other side of the aluminum car horn grille, thereby realizing double-sided etching processing;

[0009] S3: The conveyor belt can drive the etching frame and the aluminum car horn mesh inside it to be discharged from the other side of the etching box. The aluminum car horn mesh inside the etching frame can be taken out by opening the anti-dropping mesh cover. The etchant can be collected in the collection bucket and discharged through the discharge pipe by opening the discharge valve.

[0010] Based on the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the etching agent box is fixedly connected with a replenishing pipe, and the replenishing pipe is threadedly connected with a sealing cover, and the etching agent can be replenished into the etching agent box through the replenishing pipe by opening the sealing cover.

[0012] Furthermore, the conveyor belt is a mesh conveyor belt, so that the sprayed etchant can pass through the conveyor belt.

[0013] Furthermore, the anti-dropout mesh cover is provided with a clamping block, and the etching frame is provided with a clamping groove corresponding to the clamping block, so that the anti-dropout mesh cover can be clamped at the etching frame.

[0014] Furthermore, the laser receiver is connected to the brake stepper motor signal. When the laser receiver receives the laser, it can send a signal to the brake stepper motor. When the brake stepper motor receives the signal, it can reverse 180 degrees.

[0015] Furthermore, both sides of the etching box are provided with through holes, so that the conveyor can pass through the etching box.

[0016] Furthermore, a collecting hopper is provided at the bottom of the inner wall of the etching box.

[0017] The beneficial effects of the present invention are as follows: the present invention provides a double-sided etching method for an aluminum automobile speaker grille, which has the following advantages:

[0018] 1. Open the anti-drop cover of the etching frame on the right end and place the aluminum car horn mesh with hardened ink in the etching frame for loading. The conveyor belt in the conveyor can load the aluminum car horn mesh in the etching frame. This loading method does not need to turn over the aluminum car horn mesh to achieve double-sided etching processing;

[0019] 2. Start the water pump to pump the etchant in the etchant box into the drain pipe. The etchant can be sprayed out through the spray head at the bottom of the drain pipe, so as to etch one side of the aluminum car horn mesh cover in the etching frame. When the etching frame moves to the middle of the conveyor, the laser receiver of the motor box can receive the laser emitted by the laser transmitter. The laser receiver can send a signal to the brake stepper motor after receiving the laser. The brake stepper motor can drive the etching frame and the aluminum car horn mesh cover inside it to flip 180 degrees after receiving the signal, so that the spray head can spray the etchant on the other side of the aluminum car horn mesh cover, thereby realizing double-sided etching processing;

[0020] 3.
