[0002] Screen printing on mobile phone glass covers is a process of printing on the surface of mobile phone glass covers. Through specific silk screens and inks, patterns, words, etc. are printed on the glass covers to play roles such as decoration and identification. Before screen printing on mobile phone glass covers, it is usually necessary to remove dust from the surface of the glass covers. This is because if there are impurities such as dust on the surface of the glass covers, it will affect the quality of screen printing, resulting in problems such as unclear patterns and defects. Dust removal can ensure better screen printing effects, making the product appearance more beautiful and the quality more reliable.

[0003] Currently, the dust removal method before screen printing on mobile phone glass covers is mostly to use a sticky roller to roll on the surface of the mobile phone glass cover, and use the stickiness of the sticky roller to remove dust. However, after the sticky roller is used for a period of time, a lot of dust will adhere to its surface, which reduces the adhesiveness of the sticky roller, and it is also easy to have the problem that the previously removed dust falls on the mobile phone glass cover during the contact process during dust removal, resulting in insufficient dust removal effect. Therefore, technical personnel in this field have provided a screen printing dust removal device for mobile phone glass covers to solve the problems raised in the above background art.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0027] Please refer to the attached Figures 1 - 4 As shown, a silk screen dust removal device for a mobile phone glass cover plate in an embodiment of the present utility model includes a conveyor belt 1 and a glass cover plate 8. The glass cover plate 8 is arranged on the surface of the conveyor belt 1. The conveyor belt 1 is used to convey the glass cover plate 8 to the dust removal area, and after the dust removal is completed, it is conveyed out, which can continuously remove dust and has high working efficiency.

[0028] A housing 2 is fixedly connected to the middle part of the conveyor belt 1. Two dust sticking mechanisms 3 are symmetrically arranged inside the housing 2. A lifting mechanism 7 is fixedly connected to the rear end surface of the housing 2, and the lifting mechanism 7 is fixedly connected to a lateral adjustment mechanism 4. Two dust sticking mechanisms 3 are provided, which can successively remove dust from the surface of the glass cover plate 8, and the effect is sufficient. The provided lifting mechanism 7 is used to adjust the height of the lateral adjustment mechanism 4, facilitate the tensioning of the dust sticking tape 34 and adjust the distance between the dust sticking tape 34 and the surface of the conveyor belt 1, and can adapt to glass cover plates 8 of different thicknesses, ensuring that the dust sticking tape 34 can fully contact the glass cover plate, and improving the scope of application.

[0029] The dust sticking mechanism 3 includes a lower rotating shaft 31 and an upper rotating shaft 32 that are rotatably connected to the housing 2. Winding rollers 33 are sleeved on the outer ends of the lower rotating shaft 31 and the upper rotating shaft 32. A dust sticking tape 34 is wound between the two winding rollers 33. The sticky surface of the dust sticking tape 34 is located on the outside. When in use, since the sticky surface of the dust sticking tape 34 is on the outside, when it contacts the surface of the glass cover plate 8, it can remove the dust on the surface of the glass cover plate 8 through its stickiness. At the same time, through the rotation of the lower rotating shaft 31 and the upper rotating shaft 32, the used dust sticking tape 34 will be wound up, so as to always maintain the best dust sticking effect and prevent the problem that the dust removed before returns to the glass cover plate 8 again.

[0030] The horizontal adjustment mechanism 4 includes a horizontal adjustment base 41. Two sliding platforms 42 are slidably connected to the inner side of the horizontal adjustment base 41. Roller 43 is rotatably connected to the front end face of the sliding platform 42. The two dust sticking tapes 34 are respectively wound around the lower sides of the two rollers 43 and the lower surfaces thereof contact the glass cover plate 8. The two rollers 43 are provided to make the dust sticking tape 34 contact the glass cover plate 8 and tension the dust sticking tape 34. At the same time, the distance between the rollers 43 is adjustable, which is convenient for adapting to glass cover plates 8 of different sizes and has a wide application range.

[0031] The dust sticking mechanism 3 further includes two synchronous belt pulleys 35 and a first motor 37. The two synchronous belt pulleys 35 are respectively fixedly connected to the lower rotating shaft 31 and the upper rotating shaft 32. A synchronous belt 36 is connected between the two synchronous belt pulleys 35. The first motor 37 is fixed to the housing 2 and its output end is fixedly connected to one of the synchronous belt pulleys 35. Driven by the first motor 37, through the transmission of the two synchronous belt pulleys 35 and the synchronous belt 36, the lower rotating shaft 31 and the upper rotating shaft 32 are driven to rotate in the same direction, so as to drive the dust sticking tape 34 to be wound up and pulled out.

[0032] The lifting mechanism 7 includes two connecting seats 71 fixedly connected to the rear end face of the housing 2. A lifting seat 74 is slidably connected between the two connecting seats 71. The lifting seat 74 is fixedly connected to the horizontal adjustment base 41. A lifting lead screw 72 is rotatably connected to the middle part between the two connecting seats 71. The upper end of the connecting seat 71 on the upper side is fixedly connected with a third motor 73. The output end of the third motor 73 is fixedly connected to the lifting lead screw 72. The lifting seat 74 is sleeved on the lifting lead screw 72. When lifting, driven by the third motor 73, the lifting lead screw 72 is driven to rotate, so as to drive the lifting seat 74 to move and adjust the height of the horizontal adjustment mechanism 4, which is convenient for tensioning the dust sticking tape 34 and adjusting the distance between the dust sticking tape 34 and the surface of the conveyor belt 1.

[0033] The lateral adjustment mechanism 4 further includes a bidirectional lead screw 45 and a second motor 44. The bidirectional lead screw 45 is rotatably connected to the inner side of the lateral adjustment base 41. Two sliding tables 42 are respectively sleeved on both sides of the bidirectional lead screw 45. The output end of the second motor 44 is fixedly connected to the bidirectional lead screw 45. During adjustment, driven by the second motor 44, the bidirectional lead screw 45 rotates, thereby adjusting the distance between the two sliding tables 42.

[0034] The winding directions of the two dust - sticking tapes 34 are the same, and both are in the same direction as the conveying direction of the conveyor belt 1. The winding directions of the two dust - sticking tapes 34 are consistent with the conveying direction of the conveyor belt 1, which can ensure the smooth passage of the glass cover plate 8.

[0035] A maintenance door 5 is rotatably connected to the outer side of the housing 2, and an observation window 6 is fixedly arranged on the inner side of the maintenance door 5. The provided maintenance door 5 can be opened, which is convenient for replacing the winding roller 33.

[0036] Working principle: When in use, the glass cover plate 8 is conveyed to the dust - removal area through the conveyor belt 1. When passing under the dust - sticking tape 34, since the sticky surface of the dust - sticking tape 34 is on the outer side, when it contacts the surface of the glass cover plate 8, the dust on the surface of the glass cover plate 8 can be removed by adhesion. At the same time, through the rotation of the lower rotating shaft 31 and the upper rotating shaft 32, the used dust - sticking tape 34 will be wound up, and the unused dust - sticking tape 34 will be pulled out, so that the part of the dust - sticking tape 34 in contact with the glass cover plate 8 is the unused part, thus always maintaining the best dust - sticking effect and avoiding the problem that the previously removed dust returns to the glass cover plate 8 again.

[0037] The above has described a detailed description of an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
