Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a mechanism for assisting in the removal of spilled ink. Background Technology

[0002] In inkjet or pad printing processes for the front and back glass covers of mobile phones, the shape of the product often necessitates edge repair after inkjet or pad printing, followed by removal of excess ink from the edges. Currently, the industry standard for removing excess ink from glass covers primarily involves fixing the product on a table and wiping the back of the glass and its curved edges with a metal cloth or abrasive strip. Alternatively, the product can be picked up and wiped with a metal cloth and abrasive strip to remove excess ink from the outer chamfered corners of the back cover. However, in these cleaning methods, because the product is placed on a table, the friction between the product and the table during wiping can easily knock off ink from areas where the product is exposed, leading to light leakage. Furthermore, the soft texture of the metal cloth and abrasive strip can cause them to touch areas that don't need wiping, further causing ink to fall off. In addition, when cleaning the outer chamfer of the cover plate, the hand can easily come into contact with the ink on the product body during the manual wiping process. Furthermore, when wiping at different angles, the stability of the product held by the hand is poor, and the ink on the body is easily knocked off, which can lead to light leakage and ink shortage in the product. Utility Model Content

[0003] Therefore, it is necessary to provide an auxiliary mechanism for removing excess ink that can reduce ink dripping and prevent light leakage from the product, in order to address the above-mentioned shortcomings.

[0004] A mechanism for assisting in the removal of spilled ink includes a base for placement on a workbench, a rotating shaft rotatably inserted into the upper surface of the base, and a fixture fixed to the top of the rotating shaft. The upper surface of the fixture is provided with an annular relief groove and a support portion located in the middle of the annular relief groove. The top of the support portion forms a contoured support surface for supporting a glass cover plate to be cleaned. The annular relief groove has at least two opposing product limiting surfaces. The distance between the product limiting surface and the edge of the product is less than 0.3 mm. The height of the edge of the annular relief groove opening is less than the height of the outer chamfer of the product. The vertical distance from the lowest point of the edge of the glass cover plate to be cleaned on the contoured support surface to the bottom surface of the annular relief groove is greater than 0.

[0005] In one embodiment, the vertical distance from the lowest point of the edge of the glass cover to be cleaned on the contour support surface to the bottom surface of the annular clearance groove is greater than 0.5 mm.

[0006] In one embodiment, the fixture has gripping notches on its two opposite outer surfaces that communicate with the annular clearance groove.

[0007] In one embodiment, the outer ring side of the fixture is provided with a ramp portion, the width of which gradually increases in the direction toward the base.

[0008] In one embodiment, the mechanism for assisting in clearing ink spillage further includes a mounting plate fixed to the top of the rotating shaft, and the fixture fixed to the upper surface of the mounting plate.

[0009] In one embodiment, the fixture is screwed to the mounting plate.

[0010] In one embodiment, both the mounting plate and the base are circular plate structures.

[0011] In one embodiment, the upper surface of the base is provided with an insertion hole, a bearing is installed in the insertion hole, and the lower part of the rotating shaft is inserted into the insertion hole and rotates in cooperation with the bearing.

[0012] The auxiliary ink removal mechanism of this utility model supports the fixture through a base and a rotating shaft. This facilitates the operator in adjusting the product orientation and improves the stability of the product gripping, while preventing ink spillage caused by product bumps or friction between the product and the worktable. By limiting the vertical distance from the lowest point of the glass cover edge to the bottom of the annular relief groove to be greater than 0, and the distance between the product limiting surface and the product edge to be less than 0.3mm, and by making the height of the annular relief groove opening edge less than the height of the product's outer chamfer, the mechanism achieves suspension and protection of the parts of the product that do not need to be wiped. This avoids ink rubbing caused by cleaning tools (metal cloth and abrasive strips) during cleaning, prevents light leakage and ink shortage, and improves the effect of ink spillage removal.

[0021] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Please combine Figure 1-8This utility model discloses an auxiliary ink removal mechanism 10 that can reduce ink spillage and prevent light leakage from the product. The auxiliary ink removal mechanism 10 includes a base 100 for placing on a workbench, a rotating shaft 200 rotatably inserted into the upper surface of the base 100, and a fixture 300 fixed to the top of the rotating shaft 200. The base 100 and the rotating shaft 200 are used together to support the fixture 300. The fixture 300 is used to support the glass cover plate 20 for cleaning. The rotating shaft 200 is used to drive the fixture 300 to rotate relative to the base 100 under the action of external force, so as to adjust the angle and direction of the product. The upper surface of the fixture 300 is provided with an annular relief groove 310 and a support portion 320 located in the middle of the annular relief groove 310. The top of the support portion 320 forms a contoured support surface 321 for supporting the glass cover plate 20 to be cleaned. The shape of the contoured support surface 321 is adapted to the shape of the lower surface of the glass cover plate 20 to be cleaned. In this way, when the product is placed on the top of the support portion 320, the lower surface of the product can be tightly fitted with the contoured support surface 321 to prevent the product from shaking during the ink wiping process, which is convenient for operators. The annular relief groove 310 has at least two oppositely arranged product limiting surfaces 311. The two product limiting surfaces 311 are used together to limit the product and prevent the product from shaking in the horizontal direction. In this embodiment, the distance 'a' between the product limiting surface 311 and the product edge is less than 0.3 mm. This prevents the metal cloth or abrasive strip from entering the gap between the product and the fixture 300 during ink overflow cleaning, avoiding ink rubbing and preventing ink from falling off due to contact with the inner wall of the annular relief groove 310, thus protecting the edge-repairing ink on the product body. It also prevents the product from shaking within the fixture 300. The height of the annular relief groove 310 opening edge is less than the height of the product's outer chamfer position to avoid the annular relief groove 310 opening edge obstructing the metal cloth when it is higher than the product's outer chamfer position, thus preventing ink wiping difficulties. The vertical distance 'b' from the lowest point of the edge of the glass cover 20 to be cleaned on the contour support surface 321 to the bottom surface of the annular relief groove 310 is greater than 0. In a further preferred embodiment, the vertical distance b from the lowest point of the edge of the glass cover plate 20 to be cleaned on the contour support surface 321 to the bottom surface of the annular relief groove 310 is greater than 0.5mm. This can prevent the bottom surface of the annular relief groove 310 from rubbing off the ink at the lower edge of the product, thus protecting the edge-repairing ink on the product body.

[0023] The base 100 can be placed directly on the worktable, pasted onto the worktable, or fixed to the worktable with screws to prevent the base 100 from shifting during product wiping. In this embodiment, the mechanism 10 for assisting in removing excess ink also includes a mounting plate 400, which is fixed to the top of the rotating shaft 200, and the fixture 300 is fixed to the upper surface of the mounting plate 400. By providing the mounting plate 400, a gripping part is provided during product orientation adjustment to reduce the difficulty of product orientation adjustment. The mounting plate 400 can be fixed to the top of the rotating shaft 200 with screws or pins. Furthermore, both the mounting plate 400 and the base 100 are circular plate structures. Of course, the shapes of the mounting plate 400 and the base 100 can also be other plate structures, such as rectangular plates, regular pentagonal plates, regular hexagonal plates, or other regular polygonal plates, or other irregularly shaped plates.

[0024] The fixture 300 can be fixed to the mounting plate 400 in a non-removable manner, for example, the fixture 300 and the mounting plate 400 are integrally formed, or it can be fixed to the mounting plate 400 in a detachable manner, for example, by using a snap-fit ​​connection. In this embodiment, the fixture 300 and the mounting plate 400 are connected by screws. Preferably, the top surface of the support 320 has a countersunk hole 322 penetrating the lower surface of the fixture 300, and the upper surface of the mounting plate 400 has a threaded hole 410 corresponding to the countersunk hole 322. The fixture 300 is fixedly connected to the mounting plate 400 by screws 420 that pass through the countersunk hole 322 and are inserted into the threaded hole 410. Further, the upper surface of the base 100 has an insertion hole 110, a bearing 120 is installed in the insertion hole 110, and the lower part of the rotating shaft 200 is inserted into the insertion hole 110 and rotates with the bearing 120. By installing a bearing 120 inside the socket 110, the stability of the shaft 200 installation is improved, and the smoothness of the shaft 200 rotation is enhanced.

[0025] In one embodiment, the jig 300 has gripping notches 330 on its two opposite outer surfaces that communicate with the annular relief groove 310. The width of the gripping notches 330 needs to be sufficient to allow at least one finger to be inserted to facilitate the removal of the product from the jig 300. Preferably, in this embodiment, the jig 300 has a rectangular structure, with gripping notches 330 on its two long sides and product limiting surfaces 311 formed on the inner sides of its two short sides. Furthermore, the jig 300 has a ramp portion 340 on its outer ring side, the width of which gradually increases in the direction toward the base 100 to facilitate the cleaning of the product's edges by cleaning tools (metal cloth or abrasive strip).

[0026] The auxiliary ink removal mechanism 10 of this utility model supports the fixture 300 through the base 100 and the rotating shaft 200. While facilitating the operator to adjust the product direction and improving the stability of the product gripping, it can avoid ink drop caused by product bumps or friction between the product and the worktable. By limiting the vertical distance from the lowest point of the edge of the glass cover plate 20 to the bottom surface of the annular relief groove 310 to be greater than 0, and the distance between the product limiting surface 311 and the product edge to be less than 0.3mm, and making the height of the edge of the annular relief groove 310 less than the height of the outer chamfer of the product, it achieves the suspension and protection of the parts of the product that do not need to be wiped. This can prevent the ink from being rubbed off due to accidental contact by cleaning tools (metal cloth and abrasive strip) during cleaning, prevent light leakage and ink shortage, and improve the effect of ink removal.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
