Description

Technical Field

[0001] This utility model relates to the field of glass ink printing, and in particular to a 3D glass edge ink overflow removal device. Background Technology

[0002] Existing electronic devices, such as 3D front cover glass products for mobile phones, require printing ink. Due to the chamfered design of the product's front, current screen printing processes require the ink to cover more than half of the chamfered area to prevent light leakage. (Reference) Figure 1 Due to the chamfered design and display on the front of the product, light is reflected from inside the front cover and emitted through the chamfered area under the action of the display module. In dark environments, the illuminated module will show a ring of light around the edges. Therefore, the ink coverage needs to extend above the chamfered area to prevent light leakage. However, excessive ink can cause appearance problems. Current processes first slightly overflow ink onto the product, then use a laser to remove the excess. Existing technology for laser removal of edge ink overflow first uses a 3D camera to scan and locate the ink overflow area. After locating, the laser processing width is limited before correcting the ink overflow position. This results in areas without ink overflow (where the ink unevenly covers the convex edge) being processed, indirectly leading to white edges after laser removal and affecting the strength of the glass itself. Furthermore, the ink overflow removal process is time-consuming, requiring additional machines to meet production line requirements, and costs increase with production volume.

[0003] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is: to construct a 3D glass edge ink overflow removal device, which includes:

[0006] Horizontal rotary table;

[0007] A vacuum adsorption fixture is coaxially and vertically mounted on the horizontal rotating table and can rotate with it. It is used to position the product to be processed on its top and then adsorb the product by vacuum adsorption. The product is placed face up on the top of the vacuum adsorption fixture.

[0008] The limiting component is slidably fitted on the outer peripheral wall of the vacuum adsorption fixture and is lower than the top of the vacuum adsorption fixture. It is used to be manually lifted and slid up to a position higher than the top of the vacuum adsorption fixture before the product is vacuum adsorbed, so as to assist in positioning the product.

[0009] The wiping cloth wiping mechanism is located beside the horizontal rotating table and the vacuum adsorption fixture and is in contact with the chamfer of the product. It is used to wipe away ink spillage from the chamfer of the product during the rotation of the product by the vacuum adsorption fixture.

[0010] Furthermore, in the 3D glass edge ink removal device of this utility model, the radial dimension of the top edge of the vacuum adsorption fixture and the radial dimension of the outer peripheral wall are consistent and match the maximum radial dimension of the product, and the inner wall of the limiting member is clearance-fitted with the outer peripheral wall of the vacuum adsorption fixture.

[0016] Furthermore, in the 3D glass edge ink overflow removal device of this utility model, the wiping cloth wiping mechanism includes a feeding feeder, a wiping head, and a receiving feeder.

[0017] Furthermore, in the 3D glass edge ink overflow removal device of this utility model, the wiping cloth wiping mechanism also includes a vertically arranged mounting plate. The feeding feeder, wiping head, and receiving feeder are installed on the same side of the mounting plate. The wiping head is triangular with one of its sharp corners serving as the wiping angle in contact with the product. The wiping cloth covers the wiping angle. An arc-shaped groove is formed on the wiping head near the wiping angle. A fixing member passes through the arc-shaped groove to fix the wiping head to the mounting plate, so that the wiping angle of the wiping angle can be adjusted by adjusting the position of the fixing member in the arc-shaped groove.

[0031] To address the reliability and cost issues of existing laser ink removal solutions for 3D glass edges, this invention proposes a 3D glass edge ink removal device. The device includes a horizontal rotating stage, a vacuum suction clamp, a limiting component, and a wiping cloth mechanism. The vacuum suction clamp is coaxially and vertically mounted on the horizontal rotating stage and can rotate with it. The limiting component is slidably fitted onto the outer peripheral wall of the vacuum suction clamp. This invention allows manual lifting of the limiting component to position the product on top of the vacuum suction clamp, which then adheres and secures the product. The wiping cloth mechanism is located beside the horizontal rotating stage and the vacuum suction clamp, contacting the chamfer of the product. During testing, the vacuum suction clamp rotates with the product, and the wiping cloth mechanism wipes the chamfer to remove excess ink. Thus, even if no ink-overflowing area is processed, there is no need to worry about white edges or impact on the glass's strength. The investment in equipment is directly reduced, shifting from requiring laser equipment and 3D imaging equipment to manual clamp operation. Operation is simple, requires no specialized knowledge, and training is sufficient for immediate use. It is highly efficient and convenient, and the clamp positioning improves production speed.

[0032] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate typical embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. It should be understood that the embodiments of this utility model and the specific features thereof are detailed descriptions of the technical solutions of this application, and not limitations thereof. Where there is no conflict, the embodiments of this utility model and the technical features thereof can be combined with each other.

[0033] refer to Figure 2 Before introducing the 3D glass edge ink overflow removal device of this embodiment, the inkjet principle of 3D glass will be explained first. The product processed by this utility model is 3D glass, which includes a front and a back. The front is the user surface and is convex, with chamfered edges. The back is concave. Generally, after cleaning the product, window ink is printed on the back of the product, and after curing, a protective film is applied. The purpose of the protective film is to prevent ink from being sprayed onto this area later. The product with the protective film applied is then sprayed with ink, such as... Figure 2 This is a schematic diagram of the inkjet fixture. During ink spraying, the 3D glass product is placed in the inkjet fixture with its back side facing up. The chamfered portion of the product's front side fits snugly into the inkjet fixture. The sprayed ink overflows to the edge of the front side (i.e., the chamfered portion) to a height of 1mm, with a thickness of approximately 30µm. After spraying, the product is baked at 170°C for 30 minutes, and then the overflow ink is wiped out using the 3D glass edge ink overflow removal device of this embodiment.

[0034] refer to Figure 3 The 3D glass edge ink removal device of this embodiment includes a horizontal rotating stage (not shown in the figure), a vacuum adsorption fixture 2, a wiping cloth wiping mechanism 3, a limiting component 4, a coarse positioning block 5, a base 6, a linear slide rail 7, and a powder collection system 8.

[0035] The vacuum adsorption fixture 2 is coaxially and vertically mounted on the horizontal rotating table and can rotate with it. The product 1 is placed face up on top of the vacuum adsorption fixture 2, that is, the convex side of the product 1 is facing up and the concave side is facing down. The vacuum adsorption fixture 2 is used to position the product 1 to be processed on top and then hold the product 1 by vacuum adsorption. The wiping cloth wiping mechanism 3 is located beside the horizontal rotating table and the vacuum adsorption fixture 2, and the wiping cloth wiping mechanism 3 contacts the chamfer 101 of the product 1. The wiping cloth wiping mechanism 3 is used to wipe away excess ink from the chamfer 101 of the product 1 as the vacuum adsorption fixture 2 rotates with the product 1.

[0036] In this embodiment, the base 6 is a marble base, and the horizontal rotating platform and the wiping cloth mechanism 3 are mounted on the base 6. The horizontal rotating platform is mounted on the base 6, but it is not shown in this embodiment because it is hidden in a recess in the base 6. The horizontal rotating platform can be implemented using a rotary motor.

[0037] Specifically, the outer peripheral wall of the vacuum adsorption fixture 2 is cylindrical, and a vacuum adsorption hole 201 is formed inside the vacuum adsorption fixture 2 along its central axis. The vacuum adsorption hole 201 extends and penetrates the top of the vacuum adsorption fixture 2. The vacuum adsorption hole 201 is sealed and fitted with the vacuum flow channel locking position 9, and the vacuum flow channel is connected to the negative pressure device.

[0038] In this embodiment, a coarse positioning block 5 is preferably also provided, which is coaxially fixed to the top of the vacuum adsorption fixture 2 by means of screws or other connectors or by plugging. The top edge of the coarse positioning block 5 contacts the chamfer on the back of the chamfer 101 to achieve coarse positioning of the product 1. A through hole is provided in the center of the coarse positioning block 5 to avoid the vacuum adsorption hole 201 of the vacuum adsorption fixture 2.

[0039] The radial dimension of the top edge of the vacuum adsorption fixture 2 and the radial dimension of its outer peripheral wall are consistent and match the maximum radial dimension of the product 1. A limiting member 4 is slidably fitted onto the outer peripheral wall of the vacuum adsorption fixture 2. The inner wall of the limiting member 4 is in clearance fit with the outer peripheral wall of the vacuum adsorption fixture 2. Specifically, the limiting member 4 is a cylindrical ring that is in clearance fit with the outer peripheral wall of the vacuum adsorption fixture 2, and the axial dimension of this ring is smaller than the axial dimension of the cylinder of the outer peripheral wall of the vacuum adsorption fixture 2.

[0040] Normally, under the influence of gravity, the limiting member 4 slides to the bottom, thus it is lower than the top of the vacuum adsorption clamp 2. When product 1 needs to be placed, the limiting member 4 is first manually lifted. When the limiting member 4 slides up to a position higher than the top of the vacuum adsorption clamp 2, it can assist in positioning the product 1 placed on top of the vacuum adsorption clamp 2. After the product is positioned, the vacuum equipment is turned on, and product 1 is adsorbed and fixed by the vacuum adsorption clamp 2. At this time, the limiting member 4 can be released, and it slides back down, so that being lower than the top of the vacuum adsorption clamp 2 will not affect the wiping function.

[0041] The wiping cloth wiping mechanism 3 is specifically mounted on the base 6 via a linear slide rail 7. The linear slide rail 7 is located on the base 6 and extends radially along the horizontal rotating table. The wiping cloth wiping mechanism 3 is slidably mounted on the linear slide rail 7, sliding and engaging with it. After sliding to a suitable position, it is locked. The locking method is not limited and can be as simple as using screws for locking. The operator can move the wiping cloth wiping mechanism 3 along the linear slide rail 7 to a suitable position to adjust the contact area with the product 1.

[0042] The wiping cloth wiping mechanism 3 includes a feeding feeder 301, a wiping head 303, and a receiving feeder 302. The wiping cloth is steel wool cloth, which is wound around the feeding feeder 301, passes around the wiping head 303, and then wraps around the receiving feeder 302. The wiping head 303 contacts the chamfer 101 of the product 1 through the steel wool cloth.

[0043] More specifically, the wiping cloth wiping mechanism 3 also includes a vertically arranged mounting plate. The feeding feeder 301, wiping head 303, and receiving feeder 302 are arranged in a triangle and installed on the same side of the mounting plate. Specifically, the feeding feeder 301 and receiving feeder 302 are vertically aligned and spaced apart. The wiping head 303 is triangular, with one of its pointed corners extending beyond the edge of the mounting plate to contact the product 1. The steel wool cloth is as close as possible to the two sides of the wiping angle that make up the wiping angle of the wiping head 303 and covers the wiping angle.

[0044] To facilitate adjustment of the wiping angle, the wiping head 303 is secured to the mounting plate by two bolts. One bolt is positioned away from the wiping angle to pre-fix the wiping head 303. An arc-shaped groove is formed on the wiping head 303 near the wiping angle, and the other bolt passes through this groove to fix the wiping head 303 to the mounting plate. Therefore, the wiping angle can be adjusted by adjusting the position of the bolt in the arc-shaped groove.

[0045] This embodiment also preferably includes a powder collection system 8, which includes a powder collection box and an air duct. One end of the air duct is connected to the collection box and the other end is connected to an exhaust fan and is directed downward toward the wiping head 303.

[0046] The operation process for removing spilled ink from a product in this embodiment is as follows: The limiting member 4 is manually lifted to a position higher than the top of the vacuum adsorption fixture 2. The product 1, which has been sprayed back, is placed on top of the vacuum adsorption fixture 2 with its front side facing up and its back side facing down, and simultaneously inverted onto the coarse positioning block 5. The maximum edge of the chamfer 102 of the product 1 is restricted by the inner wall of the limiting member 4. Vacuum adsorption is activated, and the vacuum adsorption fixture 2 adsorbs and fixes the back of the product 1, preventing slippage and damage during the removal of spilled ink. The limiting member 4 is released, sliding back to its original position, now lower than the top of the vacuum adsorption fixture 2. The mounting plate of the wiping cloth wiping mechanism 3 is moved to a suitable position so that the wiping head 3033 contacts the chamfer 101 of the product 1, and the contact angle of the wiping head 303 is adjusted and fixed. Start the rotary motor and adjust the speed to 60 RPM. The vacuum adsorption fixture 2 rotates, and the vacuum adsorption fixture 2 rotates with the product 1. During the rotation, the steel wool of the wiping head 303 is used to wipe away the excess ink on the chamfer 102 of the product 1. After processing for 30 seconds, some of the ink is removed. During the removal process, the exhaust fan is turned on to collect the airborne ink powder. After completion, it can be sent to the next process for inspection.

[0047] In summary, the 3D glass edge ink overflow removal device of this utility model has the following beneficial effects: This utility model allows for manual lifting of the limiting component to position the product, followed by the use of a vacuum adsorption clamp to hold the product in place. The vacuum adsorption clamp rotates the product, and during this rotation, a wiping cloth wiping mechanism cleans the product's chamfer to remove excess ink. Thus, even if no ink overflow area is processed, there is no need to worry about white edges or the impact on the strength of the glass itself. The investment in the machine is directly reduced, transforming the need for laser equipment and 3D imaging equipment into manual clamp operation. The operation is simple, requires no professional knowledge, and training is sufficient for immediate use. It is highly efficient and convenient, and the production pace is improved through clamp positioning.
