[0002] The edge filling of the back cover of the mobile phone glass cover is usually done by spraying ink on all sides of the product using a dot-spray machine to achieve the effect of filling the edge. However, since the product window needs to be attached to the film before various auxiliary materials are attached, the cleanliness of the window is required to be high. If there is ink splashing, it will affect the subsequent attachment of auxiliary materials. Therefore, to avoid this problem, a metal masking jig is needed to mask the window when filling the edge. The currently used edge filling masking jig is an integrated molding that can only be used for one project. It cannot be disassembled and reused, and it is difficult to clean. In the production process, if the jig is used many times and the ink is thick, the jig will fit closely to the product, and the product can only fall off naturally due to gravity. It needs to wait for it to fall off naturally. Some products take a long time to fall off, for example, it usually takes 30 seconds, which greatly affects production efficiency, and there is a risk of edge collapse after falling.

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings below. Typical embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0033] Embodiment 1

[0034] refer to Figure 1 The inkjet edge-filling masking fixture of this embodiment includes a bottom cover plate 1, a pusher 2, and a knob 3.

[0035] refer to Figure 2 The bottom cover plate 1 includes an upper surface and a lower surface that are arranged opposite to each other. The size of the lower surface matches the product to be inkjetted so as to fit on the product to be inkjetted. Taking a mobile phone as an example, the lower surface of the bottom cover plate 1 fits the glass back cover of the mobile phone and is rectangular. The bottom cover plate 1 is provided with a vent hole 11 that starts from the upper surface of the bottom cover plate 1 and runs through the thickness of the bottom cover plate 1 to the lower surface. The vent hole 11 is preferably designed at the center of the bottom cover plate 1.

[0036] The bottom cover plate 1 is also provided with an assembly position for installing the knob 3, and the ejector 2 is detachably assembled on the upper surface of the bottom cover plate 1 based on the installation of the knob 3 and the assembly position. The ejector 2 is directly facing the vent hole 11, and is used to increase air pressure to the product through the vent hole 11, so that the product and the bottom cover plate 1 can fall off quickly.

[0037] refer to Figure 4-6 , Figure 4 It's a top-down angle. Figure 5 It is a biased upward viewing angle, and the ejector 2 includes an ejector tube 21, an ejector plug 22, an ejector rod 23, a pressing head 24, and a spring 25. In this embodiment, the ejector tube 21, the ejector plug 22, and the ejector rod 23 are all made of stainless steel.

[0038] The ejection tube 21 includes a column body 211, a finger-lifted wing 212, and a fixing plate 213. In this embodiment, the column body 211 is a cylinder, and the column body 211 is hollow inside to form an air cavity. Of course, in other embodiments, the column body 211 can also be other shapes, as long as the air cavity can be provided inside, and the shape of the outer peripheral surface is not limited.

[0039] In this embodiment, the ejection plug 22 is in the shape of a round cake, i.e., a relatively short cylinder, and the air cavity is a relatively long cylindrical shape, the radial dimension of the air cavity matches the radial dimension of the ejection plug 22, and the ejection plug 22 is sealed and sleeved in the air cavity and can move along the axial direction of the air cavity. Of course, it is understandable that the shape of the outer circumference of the ejection plug 22 is not limited to a cylindrical shape, but can also be any other shape, and the shape of the corresponding air cavity can also change with the shape of the outer circumference of the ejection plug 22.

[0040] The air cavity is downwardly connected to the vent 11. Specifically, the bottom of the column body 211 is completely open, that is, the air cavity directly penetrates the bottom of the column body 211, and the radial size of the air cavity and the radial size of the ejection plug 22 are much larger than the radial size of the vent 11. The horizontal projections of the air cavity and the ejection plug 22 cover the horizontal projection of the vent 11. The vent 11 is preferably located at the center position directly below the air cavity and the ejection plug 22. The top of the column body 211 is not completely open, but only a through hole is opened in the center area of ​​the top of the column body 211. The through hole is connected to the air cavity, and the radial size of the through hole is much smaller than the radial size of the air cavity. The purpose of the through hole is to facilitate the ejection rod 23 to pass through.

[0041] The so-called horizontal projection in this article can be understood as a projection on a horizontal plane, and the horizontal plane can be understood as a plane parallel to the lower surface of the bottom cover plate 1.

[0042] The wing 212 and the fixing plate 213 are both connected to the outer peripheral wall of the column body 211, and the wing 212 is close to the top of the column body 211 to facilitate lifting the entire ejector 2. In this embodiment, the top surface of the wing 212 is flush with the top surface of the column body 211. The fixing plate 213 is close to the bottom of the column body 211 to cooperate with the assembly position to realize the detachable assembly of the ejector 2. In this embodiment, the bottom surface of the fixing plate 213 is flush with the bottom surface of the column body 211. The bottom surface of the column body 211 and the bottom surface of the fixing plate 213 are both in contact with the upper surface of the bottom cover plate 1.

[0043] In addition, in this embodiment, the number of the wings 212 is a pair, and the number of the fixing plates 213 is a pair, and the pair of wings 212 is arranged opposite to each other, and the pair of fixing plates 213 is arranged opposite to each other. The horizontal projections of the wings 212 and the fixing plates 213 form a preset angle, such as 90 degrees. It can be understood that the number of the wings 212 and the fixing plates 213 can also be adjusted.

[0044] Among them, the lower surface of the push plug 22 faces the vent 11, and the upper surface of the push plug 22 is vertically connected to the push rod 23. The radial dimension of the push rod 23 is smaller than the radial dimension of the through hole at the top center of the column body 211. The push rod 23 extends out of the through hole in a direction away from the upper surface of the push plug 22. When the push rod 23 pushes the push plug 22 to move toward the bottom cover plate 1, the air between the push plug 22 and the product is compressed to make the product quickly fall off from the bottom cover plate 1.

[0045] Preferably, the end of the ejection rod 23 extending out of the through hole is connected to a pressing head 24, the radial dimension of the pressing head 24 is larger than the radial dimension of the through hole, and a spring 25 is sheathed on the outer surface of the ejection rod 23, and the spring 25 is supported between the pressing head 24 and the top of the ejection tube 21 for resetting the ejection plug 22.

[0046] Specifically, the pressing head 24 includes a gasket 241 and a locking head 242. The gasket 241 is in a circular ring shape and is sleeved outside the ejection rod 23, and its purpose is to limit the spring 25. The locking head 242 is threadedly connected to the ejection rod 23, and its purpose is to press the gasket 241. The longitudinal section of the locking head 242 is T-shaped, and is divided into a large head in the shape of a round pancake and a small head in the shape of a cylinder. The small head has an external thread that cooperates with the internal thread of the ejection rod 23. A hexagonal hole is opened on the top of the large head for cooperation with a hexagonal tool, and the locking head 242 is tightened on the ejection rod 23 by the tool. The large head of the locking head 242 is against the top of the gasket 241 to press the gasket 241 to achieve the effect of limiting the spring 25.

[0047] Furthermore, an annular protrusion 214 protrudes from the top of the ejection tube 21 in the axial direction, the center of the annular protrusion 214 coincides with the center of the through hole, and the radial dimension of the annular protrusion 214 is greater than the radial dimension of the through hole, so that the annular protrusion 214 is arranged around the through hole and is a certain distance away from the edge of the through hole. The top of the spring 25 abuts against the gasket 241, and the bottom of the spring 25 abuts against the area between the annular protrusion 214 and the through hole, and the lower half of the spring 25 is confined in the annular protrusion 214.

[0048] Furthermore, the outer peripheral wall of the ejection rod 23 also protrudes in the radial direction to form an annular flange 231, and the annular flange 231 is located inside the air cavity. The radial dimension of the annular flange 231 is greater than the radial dimension of the through hole, so when the spring 25 drives the ejection rod 23 to reset, the annular flange 231 will rise to the top of the column body 211, thereby limiting the initial position of the ejection rod 23.

[0049] The fixing plate 213 is connected to the assembly position of the bottom cover plate 1 through a knob 3. Specifically, the knob 3 includes a vertically arranged rotation connection portion 31, a horizontally arranged strip portion 32, and a horizontally arranged gasket 33.

[0050] Specifically, the rotating connection part 31 is a cylindrical shape extending in the vertical direction, the horizontal strip part 32 is a strip structure extending in the horizontal direction, and the gasket 33 is a disc-shaped structure arranged horizontally. The bottom end of the rotating connection part 31 is connected to the horizontal strip part 32, and the gasket 33 is connected to the outer peripheral wall of the rotating connection part 31 at a waist position, and the gasket 33 is located above the horizontal strip part 32. The fixing plate 213 is provided with a cylindrical rotating hole running through its thickness. The radial size of the rotating hole matches the radial size of the rotating connection part 31, so that the rotating connection part 31 passes through the rotating hole and can rotate in the rotating hole. Preferably, the bottom of the fixing plate 213 is further recessed with the rotating hole as the center to form a receiving groove 2131, the receiving groove 2131 is in a round pancake shape, the aperture of the receiving groove 2131 is larger than the aperture of the rotating hole, the diameter of the receiving groove 2131 is the diameter of the circular area formed when the horizontal strip portion 32 rotates, and the thickness of the receiving groove 2131 is the thickness of the horizontal strip portion 32. Before the ejector 2 and the bottom cover plate 1 are assembled and fixed, the horizontal strip portion 32 can be completely received in the receiving groove 2131.

[0051] refer to Figure 3 The assembly position includes an assembly groove 12 provided on the bottom cover plate 1 and matched with the horizontal strip portion 32. The assembly groove 12 specifically includes a rotation groove 121 provided in the bottom cover plate 1 for the horizontal strip portion 32 to rotate and a socket 122 provided on the upper surface of the bottom cover plate 1. The socket 122 is located above the rotation groove 121 and communicates with the rotation groove 121. The shape and size of the socket 122 exactly match the shape and size of the horizontal strip portion 32 so that the horizontal strip portion 32 can enter the rotation groove 121 through the socket 122 only after being aligned with the socket 122. The shape and size of the rotation groove 121 allow the horizontal strip portion 32 to rotate a certain angle so that the horizontal strip portion 32 deviates from the socket 122 and cannot be separated from the rotation groove 121. The rotating groove 121 in this embodiment is specifically a circular pancake-shaped groove, which is consistent with the shape and size of the receiving groove 2131, so the rotating groove 121 allows the horizontal strip portion 32 to rotate a full circle.

[0052] The gasket 33 is located above the fixing plate 213 , and the gasket 33 is in contact with the fixing plate 213 when the horizontal strip portion 32 extends into the rotation groove 121 to the bottom, so that the gasket 33 and the horizontal strip portion 32 clamp and restrict the fixing plate 213 up and down.

[0053] In order to prompt the user whether the rotation 3 is in place and to facilitate the rotation of the rotation 3, preferably, a rotating fast 34 can be connected to the top of the rotating connection part 31, and the rotating fast 34 and the rotating connection part 31 roughly form a 7 shape. According to the direction of the rotating fast 34, it can be known whether the rotating connection part 31 is turned to the right position, and the user can also hold the rotating fast 34 to exert force to rotate the rotating connection part 31.

[0054] In this embodiment, the gasket 33, the rotating fastener 34 and the rotating connecting part 31 are integrally formed, and the horizontal strip part 32 is threadedly connected to the rotating connecting part 31. When assembling the knob 3, the rotating connecting part 31 is first inserted into the rotating hole at the bottom of the fixed plate 213, and then the horizontal strip part 32 and the rotating connecting part 31 are tightened from the bottom side of the fixed plate 213.

[0055] Before using the jig of this embodiment, first select the bottom cover plate 1 of the corresponding size according to different projects, then align the air cavity of the ejector 2 with the vent 11, align the horizontal strip portion 32 with the socket 122 and insert it into the rotating groove 121, and then rotate the rotating fast 34. For example, if the rotating fast 34 is rotated 90 degrees, it will drive the rotating connection portion 31 and the horizontal strip portion 32 to rotate 90 degrees, thereby realizing the assembly of the ejector 2 and the cover plate 1. During production, the cover plate 1 of the jig is covered on the glass back cover of the mobile phone. After the product is finished inkjet, the index finger and the middle finger are used to lift the wings 212 to take the product out of the device, and the thumb presses the pressing head 24 to push the air pressure to make the product fall off. After the material is taken, the thumb is released, and the spring 25 pushes the pressing head 24 to realize rebound reset, thereby realizing rapid material taking. After production is completed, the ejector 2 and the cover plate 1 need to be disassembled. You can refer to the previous assembly process, rotate the rotating fast 34 90 degrees in the opposite direction, and then lift the rotating fast 34 to separate the horizontal strip portion 32 from the assembly groove 12 of the cover plate 1 to achieve the disassembly of the ejector 2 and the cover plate 1.

[0056] In summary, the assembled edge-filling shielding jig of this embodiment is placed on the glass cover plate to be inkjetted when in use. When the operator takes the film, the compressed air pressure is directly pressed to quickly separate the product from the jig, preventing the glass cover plate from sticking to the product during the film-taking process, which affects production efficiency, and can effectively avoid edge collapse caused by natural film drop. Since the shielding jig can be disassembled into the ejector and the cover plate by turning the knob, it can be disassembled and assembled at will, so that the jig can be cleaned and the ejector can be reused in different projects; the rebound is achieved by the spring structure, and the addition of this structure can improve production efficiency.

[0057] Embodiment 2

[0058] refer to Figure 7-9The difference between this embodiment and the first embodiment is that the external knob 3 is not required. Instead, a guide rail groove 41 is directly provided at the bottom of the fixing plate 213, and the assembly position on the cover plate 1 is no longer the assembly groove 12, but a guide rail 42 protruding from the bottom cover plate 1. The projections of the guide rail 42 and the guide rail groove 41 in the horizontal plane are both arc-shaped, and the center of the arc is located at the central axis of the column body 211. The guide rail 42 and the guide rail groove 41 are slidably matched and the sliding track is arc-shaped.

[0059] refer to Figure 8 , 10 The cross-sections of the guide rail groove 41 and the guide rail 42 are both matched T-shaped to realize the connection between the guide rail 42 and the guide rail groove 41 in the vertical direction. The small T-shaped head of the guide rail 42 is connected to the cover plate 1, and the large head is inserted into the guide rail groove 41. The cross-section of the guide rail groove 41 is also T-shaped. In order to insert the guide rail 42 into the guide rail groove 41, refer to Fig. 9 One end of the guide rail groove 41 is connected to a notch 410 , and the notch 410 is open to the guide rail 42 and has a size that allows the guide rail 42 to be inserted into and aligned with the guide rail groove 41 . After the guide rail 42 is inserted into the notch 410 , it enters the guide rail groove 41 by rotating.

[0060] Before using the jig of this embodiment, first select the bottom cover plate 1 of corresponding size according to different projects, then align the air cavity of the ejector 2 with the vent hole 11 and align the guide rail 42 with the notch 410, then place the ejector 2 on the cover plate 1, and then insert the guide rail 42 into the notch 410, then rotate the ejector 2, turn the guide rail 42 into the guide rail groove 41, and complete the assembly of the ejector 2 and the cover plate 1. During production, the cover plate 1 of the jig is covered on the glass back cover of the mobile phone. After the product is finished inkjetted, the index finger and middle finger are used to lift the wing 212 to take the product out of the device, and the thumb presses the pressing head 24 to push the air pressure to make the product fall off. After the material is taken, the thumb is released, and the spring 25 pushes the pressing head 24 to achieve rebound reset, thereby achieving rapid material taking. After production is completed, the ejector 2 and the cover plate 1 need to be disassembled. You can refer to the previous assembly process, rotate the ejector 2 in the opposite direction, move the guide rail 42 to the slot 410, and then lift the ejector 2 to separate the guide rail 42 from the slot 410, thereby realizing the disassembly of the ejector 2 and the cover plate 1.

[0061] The jig and the ejector of this embodiment are not easily damaged, which greatly increases their service life and saves materials.

[0062] Of course, it is understandable that the guide rail 42 and the guide rail groove 41 in this embodiment can also be swapped, that is, the guide rail 42 is provided at the bottom of the fixing plate 213 and the assembly position includes the guide rail groove 41 provided on the bottom cover plate 1.
