Description

Technical Field

[0001] The utility model relates to the technical field of surface pretreatment devices, especially a surface pretreatment device for etching processing of mobile phone casings. Background Art

[0002] With the progress of society and technology, mobile terminals have rapidly penetrated into people's lives, especially mobile phones. Therefore, mobile phone casings are needed to protect mobile phones. After the metal mobile phone casings are processed, the protective film on the metal etching area of the metal mobile phone casings needs to be removed. When etching the metal, it contacts chemical solutions, which play a role in dissolving and corroding, forming concave-convex or hollow-shaped effects.

[0003] In the prior art, when etching and processing metal mobile phone casings, the etching liquid waste liquid contains a large amount of solid impurities. When recycling the etching liquid waste liquid, a filtering structure is required to separate the solid and liquid in the etching liquid waste liquid. However, after the filtering structure is used for a long time, solid waste will accumulate on the filter plate, resulting in the clogging of the mesh holes of the filter plate. As a result, it is difficult for the subsequent etching liquid waste liquid to pass through the filter plate, making it difficult for the filtering structure to perform filtering separation, leading to poor filtering effects and reducing the service life of the filtering structure. Content of the Utility Model

[0027] Please refer to Figures 1 - 4 , the present utility model provides a surface pretreatment device for etching processing of mobile phone casings.

[0028] It includes a processing box 100 for etching processing of metal mobile phone casings, a filter plate 200 for placing metal mobile phone casings is arranged in the processing box 100, a lifting device 300 for driving the filter plate 200 to move up and down is arranged in the processing box 100, and a cleaning device 400 for cleaning the solid waste on the filter plate 200 is arranged in the processing box 100.

[0029] The cleaning device 400 includes a scraping component 420 for cleaning the solid waste filtered on the filter plate 200, and a driving component 410 for driving the scraping component 420 to move back and forth is arranged above the filter plate 200. At the bottom end of the processing tank 100, support legs 001 for supporting the processing tank 100 are fixedly installed, and there are four support legs 001, and the four support legs 001 are distributed in a rectangular array at the four corners of the bottom end of the processing tank 100; so as to support the processing tank 100 through the four support legs 001. A drain pipe 002 for discharging the chemical solution in the processing tank 100 is arranged at the right end of the processing tank 100, so as to discharge and recycle the used chemical solution in the processing tank 100 through the drain pipe 002.

[0030] A slag discharge port 003 for cleaning the solid waste filtered on the filter plate 200 is arranged at the front end of the processing tank 100, and a storage groove 004 for storing the scraping component 420 is arranged at the rear side of the box body of the processing tank 100; thus, the filter plate 200 can be lifted out of the chemical solution in the processing tank 100 through the lifting component 310, and then the metal mobile phone shell after the etching process on the filter plate 200 can be taken out, and then the scraping component 420 stored in the storage groove 004 is driven by the driving component 410 to discharge the solid waste on the filter plate 200 along the slag discharge port 003; to prevent the filter holes on the filter plate 200 from being blocked, which affects the surface etching process of the next batch of metal mobile phone shells.

[0031] A guide plate 202 for sleeving on the sliding rod 320 is fixedly installed at the left end of the filter plate 200, and a threaded sleeve plate 201 for screwing with the first threaded rod 312 is fixedly installed at the right end of the filter plate 200.

[0032] The lifting device 300 includes a lifting component 310 arranged in the processing tank 100 for driving the filter plate 200 to move up and down, and a sliding rod 320 for assisting the lifting component 310 to drive the filter plate 200 to move up and down is arranged on the left side of the lifting component 310.

[0033] Among them, the lifting component 310 includes a first threaded rod 312 disposed in the processing box 100 for driving the filter plate 200 to move up and down. The upper and lower ends of the first threaded rod 312 are connected to the box body of the processing box 100 through bearings to facilitate the rotation of the first threaded rod 312. A first motor 311 for driving the first threaded rod 312 to rotate is fixedly installed at the bottom end of the first threaded rod 312, and the shaft end of the output shaft of the first motor 311 is connected to the first threaded rod 312 through a coupling to facilitate the rotation of the first threaded rod 312 when the first motor 311 is started. Thus, when it is necessary to take out the metal mobile phone case after the etching process on the filter plate 200, the first motor 311 can be used to drive the first threaded rod 312 to rotate, so that the threaded sleeve plate 201 on the right end of the filter plate 200 can move upward along the rod body of the first threaded rod 312, and at the same time, the guide plate 202 can slide on the slide rod 320. Furthermore, the filter plate 200 can be lifted above the chemical solution in the processing box 100, and then the metal mobile phone case after the etching process on the filter plate 200 can be taken out. Then, the driving component 410 is used to drive the scraping component 420 stored in the storage groove 004 to discharge the solid waste on the filter plate 200 along the slag discharge port 003, so as to prevent the filter holes on the filter plate 200 from being blocked and affecting the surface etching process of the next batch of metal mobile phone cases.

[0034] The driving component 410 includes a second threaded rod 412 for driving the scraping component 420 to move back and forth. The front and rear ends of the second threaded rod 412 are connected to the box body of the processing box 100 through bearings to facilitate the rotation of the second threaded rod 412. A second motor 411 for driving the second threaded rod 412 to rotate is fixedly installed at the front end of the second threaded rod 412, and the shaft end of the output shaft of the second motor 411 is connected to the front end of the second threaded rod 412 through a coupling to facilitate the rotation of the second threaded rod 412 when the second motor 411 is started. A guide rod 413 for assisting the second threaded rod 412 to drive the scraping component 420 to move back and forth is disposed on the left side of the second threaded rod 412.

[0035] The scraping component 420 includes a scraper 421 for cleaning the solid waste filtered at the top of the filter plate 200. A slider 423 for sleeving on the guide rod 413 is fixedly installed at the left end of the scraper 421, and a moving plate 422 for threadedly connecting with the second threaded rod 412 is fixedly installed at the right end of the scraper 421. Thus, when it is necessary to clean the solid waste filtered on the filter plate 200, when the second motor 411 drives the second threaded rod 412 to rotate, the moving plate 422 at the right end of the scraper 421 stored in the storage groove 004 can be moved forward along the rod body of the second threaded rod 412. At the same time, the slider 423 can slide along the guide rod 413, and the solid waste filtered on the filter plate 200 can be discharged along the slag discharge port 003 through the scraper 421, so as to prevent the filter holes on the filter plate 200 from being blocked and affecting the surface etching process of the next batch of metal mobile phone casings.
