Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to a cleaning device used for etching, belonging to the technical field of etching. Background Art

[0002] Etching is a technique that uses chemical reactions or physical impact to remove part of a material. Etching technology can be divided into two categories: wet etching and dry etching. It was first used to make printing embossed plates such as copper plates and zinc plates. It is also widely used to reduce the weight of instrument panels, nameplates, and thin workpieces that are difficult to process using traditional processing methods. After continuous improvements and development of process equipment, it can also be used in the processing of precision etching products for electronic thin-film parts in the aviation, machinery, and chemical industries. In particular, etching is an indispensable technology in semiconductor manufacturing processes.

[0003] A Chinese patent publication (publication number: CN 218610627 U) discloses an etching liquid cleaning device. First, the etching workpiece to be cleaned is placed on a workbench, and then the motor is turned on. The motor drives the first gear to rotate, the first gear drives the third gear to rotate, the third gear drives the V-shaped and the first rotating shaft to rotate, and at the same time, the second gear drives the fourth gear to rotate, the fourth gear drives the second rotating shaft to rotate, and the second rotating shaft drives the spray head to rotate. The liquid storage cavity is filled with cleaning liquid. The water pump flows the cleaning liquid into the spray head through the water pipe, and then sprays it out from the spray hole. This structure can make the spray device rotate a certain angle, so that the cleaning liquid sprayed by the spray head can be sprayed over a wider range, and the spray head rotates around the first rotating shaft while rotating within a certain range to increase the cleaning force. Then, through the water drop hole, the cleaned waste water flows into the waste water cavity through the water drop hole, and the waste water with etching liquid is recycled to avoid direct discharge and pollution.

[0004] However, in the cleaning process of the device, the workpiece is placed horizontally on the workbench and then cleaned through the spray head on the top. In this way, only one side can be cleaned separately. Most workpieces are often processed on multiple sides when etching. At this time, the etching part that is attached to the worktable surface cannot be cleaned, and the operator is required to turn the workpiece over for secondary cleaning, which wastes a lot of cleaning time. In addition, the device only has a drain outlet on the right side of the inner cavity of the box body. When the workpiece is cleaned, sewage will be sprayed into the inner cavity of the box body. Only a drain outlet on one side may make it impossible to completely discharge the sewage, affecting the subsequent cleaning work, and then reducing the practical effect of the cleaning device. For this reason, a cleaning device for etching is proposed. Utility Model Content

[0033] Example 3

[0034] In one embodiment, a drying mechanism 3 is provided at the rear side of the cleaning box 1, and the drying mechanism 3 includes a drying box 301, which is fixedly installed on the rear side of the cleaning box 1, and a filter screen 303 is fixedly installed in the inner cavity of the drying box 301, and an air inlet groove 302 is provided at the bottom of the inner cavity of the drying box 301, and a heating pipe 304 is fixedly installed on the top of the inner cavity of the drying box 301, and a fan 305 is fixedly installed on the top of the drying box 301, and the output end of the fan 305 is connected to an air inlet pipe 306, and the end of the air inlet pipe 306 away from the fan 305 is connected to the inner cavity of the cleaning box 1, and drying lamp covers 307 are fixedly installed on the front and back sides of the left and right sides of the inner cavity of the cleaning box 1, and a drying bulb is provided in the inner cavity of the drying lamp cover 307.

[0035] By setting up the drying mechanism 3, the rinsed workpiece can be dried, saving the operator's time in transferring the workpiece to other drying machines after cleaning. By setting up the drying lampshade 307, the drying efficiency of the workpiece can be improved and the drying speed can be accelerated.

[0036] When the utility model is working, after the water storage tank 207 infuses water into the inner cavity of the water storage tank 209 through the bellows 208, the high-pressure nozzle 210 sprays water, so that the water is sprayed onto the surface of the workpiece. At the output end of the motor 201, the first screw 205 drives the first screw block 206 and the water storage tank 209 to move up and down through the mutual cooperation between the active rotating shaft 202, the driven rotating shaft 203 and the transmission belt 204, so that the workpiece is repeatedly cleaned. At the same time, due to the rotation of the first screw 205, the connecting shaft 213 cooperates with the active gear 214 and the driven gear 215, so that the light rod 216 drives the main gear 217 to rotate. At this time, the toothed belt 219 is driven by the main gear 217 to rotate. The rotation of gear 217 causes sub-gear 218 to rotate, and the second screw rod 220 rotates synchronously with sub-gear 218. At this time, the second screw block 221 drives the scraper 222 to move back and forth along the inner cavity of the cleaning box 1, and removes the sewage generated by the washing and etching parts, so that the sewage enters the inner cavity of the sewage tank 5 through the drain port 6, and the cleaning of the workpiece is completed. Then, the fan 305 transmits the air heated by the heating pipe 304 in the drying box 301 to the air inlet pipe 306, and after it enters the inner cavity of the cleaning box 1 through the transmission of the air inlet pipe 306, the drying bulb in the drying lamp cover 307 lights up, and the washed workpiece is dried.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
