Description

Technical Field

[0001] The utility model belongs to the technical field of mobile phone processing equipment, and in particular relates to a recycling filter mechanism and a mobile phone middle frame burr removal device. Background Art

[0002] In mobile phone manufacturing, flash refers to burrs and irregular projections on the edges of metal or other material midframes after processing. Nylon sandblasting is a commonly used process for removing these irregularities, effectively improving the product's appearance and feel. According to the latest information, nylon sandblasting machines can be used to remove flash and burrs on precision plastic or metal parts such as mobile phone cases. Due to the toughness and non-cutting properties of nylon sand, it does not damage the product during use.

[0003] In the prior art, the nylon sand ejected from the sandblasting tube needs to be recycled and reused. Therefore, the nylon sand blasting equipment also includes a recovery filter. Traditional recovery filters usually use non-woven fabrics to separate burrs from the nylon sand so that the purified nylon sand can re-enter the sandblasting tube for use.

[0004] However, non-woven fabric filtration can achieve the nylon sand filtering effect by hindering the movement of large-volume particles based on its own interception or adsorption effect. The volume of nylon sand and burrs is similar, which causes the non-woven fabric to have an obstructive effect on some larger nylon sand, resulting in a decrease in filtration efficiency; even in the actual burr removal process, some burrs that fall off due to the impact of nylon sand are smaller than the nylon sand itself. These burrs can be added to the nylon sand circulation route and used as impact objects. Non-woven fabrics cannot effectively filter or identify this type of burrs; therefore, using non-woven fabrics as filtering units is not conducive to the smooth improvement of filtration efficiency and needs to be improved urgently.

[0032] Specifically, after the nylon sand and burr mixture is transported into the hopper body 100 through the feed assembly 300, it impacts the filter unit 210, and part of the mixture remains on the filter unit 210. The filter unit 210 is buffered by the impact force of the mixture through the elastic component 230. During buffering, the elastic component 230 converts elastic potential energy into kinetic energy to drive the filter unit 210 to reset. During the frequent resetting process, the filter unit 210 vibrates, causing the mixture remaining on the filter unit 210 to shake and filter the nylon sand through the filter hole 240; compared with the nylon sand sandblasting equipment in the prior art, non-woven fabric is used as the main structure for recycling and filtering nylon sand and burrs, resulting in a technical problem of low recycling and filtering effect. The recovery and filtering mechanism and the mobile phone middle frame burr removal device provided in the embodiment of the utility model use the filter unit 210 that vibrates with the material to shake off and filter the mixture blocked on the filter unit 210, effectively improving the filtering effect, improving the purity of the nylon sand, and thereby improving the burr removal effect.

[0033] In another embodiment of the present invention, the elastic component 230 includes a connecting block 231, a sliding rod 232, and an elastic member 233. The sliding rod 232 is disposed on the mounting seat 220, and the elastic member 233 is disposed on the sliding rod 232. The connecting block 231 is slidably connected to the sliding rod 232. An end of the connecting block 231 is fixedly connected to the filter unit 210, and the elastic member 233 is disposed in abutment with the connecting block 231. In this embodiment, the sliding rod 232 is disposed in a vertical direction.

[0034] In another embodiment of the present invention, a sidewall of the mounting seat 220 is provided with a slot 221, a slide rod 232 is disposed within the slot 221, a middle portion of the connecting block 231 is slidably connected to the slide rod 232, the connecting block 231 is located within the slot 221, an end portion of the connecting block 231 extends outside the slot 221, and the elastic member 233 extends along the length of the slide rod 232. In this embodiment, the connecting block 231 is a cubic structure with a slide hole disposed in the middle portion of the connecting block 231, through which the connecting block 231 is slidably connected to the slide rod 232. The slot 221 structure conceals the elastic member 230 within the mounting seat 220, thereby preventing filtered nylon sand from being trapped between the connecting block 231 and the slide rod 232 and effectively improving the smooth operation of the elastic member 230.

[0035] In another embodiment of the present invention, the elastic member 233 is a compression spring. The elastic member 233 is sleeved on the slide bar 232. The ends of the elastic member 233 respectively abut the connecting block 231 and the bottom wall of the slide groove 221.

The two ends of the filter unit 210 are respectively connected to the output ends of the corresponding elastic components 230. The use of two sets of elastic components 230 helps to improve the cushioning stability of the two ends of the filter unit 210 and also improves the smoothness of the vibration of the filter unit 210.

[0037] In another embodiment of the present invention, the filter unit 210 includes a first filter plate 211 and a second filter plate 212, which are sequentially connected along the width of the mold cavity 400.

During feeding, the blasting component 320 blows air into the feeding pipe 310, and the feeding pipe 310 generates a siphon effect on the nylon sand and flash mixture at the other input end, so that the mixture smoothly enters the silo body 100 from the feeding pipe 310, thereby accelerating the material transportation efficiency.

[0040] In another embodiment of the present invention, the bottom of the silo 100 is configured as an inclined bottom wall. A negative pressure device is connected to a pipe on the inner wall of the silo 100, near the lowest end of the inclined bottom wall. This device delivers filtered nylon sand to a pre-set sandblasting device. The inclined bottom wall facilitates the movement of filtered nylon sand in a predetermined direction, facilitating centralized processing.
