Description

Technical Field

[0001] This utility model relates to the field of 3D curved glass pad printing technology, and in particular to an ink removal assembly fixture for 3D curved glass pad printing. Background Technology

[0002] The ink removal fixture for 3D curved glass pad printing is an auxiliary tool used to remove excess ink from the pad printing steel plate during the 3D curved glass pad printing process. It is composed of components such as an acrylic main board, aluminum pads, and strong magnets.

[0003] In the 3D curved glass pad printing process, the principle is that the ink cup slides across the pad printing steel plate, leaving the required ink on the plate. The pad printing head picks up the ink from the steel plate and then transfers it onto the 3D curved glass. However, during this process, a large amount of excess ink may be left on the steel plate and the ink cup. If it is not removed in time, it will affect the subsequent pad printing quality. Therefore, it is necessary to use an ink removal fixture to remove the excess ink.

[0004] The existing ink removal fixture for 3D curved glass pad printing has the following shortcomings:

[0005] Because the end face of the contact steel plate is not sharp enough and has a chamfer, the process of scraping off the ink from the steel plate is not smooth and cannot completely remove excess ink. At the same time, the existing device is not properly adjusted because the width of the aluminum pad is too wide or too narrow. This not only makes it inconvenient to apply ink, but also easily damages the pad printing steel plate, affecting the pad printing effect and the service life of the steel plate. Utility Model Content

[0006] This utility model mainly provides an ink removal fixture for 3D curved glass pad printing that can efficiently remove excess ink from 3D curved glass pad printing steel plates and avoid damaging the pad printing steel plates.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a combination fixture for removing ink from 3D curved glass pad printing, comprising an acrylic main board, an aluminum pad, and hexagonal screws. The top of the acrylic main board has seven filling holes, the interior of which is filled with strong magnets. The acrylic main board is connected to the aluminum pad via hexagonal screws, the hexagonal screws being M5*16mm in size. The aluminum pad has two threaded holes, and the material of the aluminum pad is aluminum alloy A6061. The acrylic main board has countersunk holes, and the hexagonal screws pass through the countersunk holes and connect to the threaded holes on the aluminum pad. The end face of the acrylic main board that contacts the steel plate is at a right angle, and the end face is not chamfered.

[0008] Preferably, the main body of the acrylic motherboard is made of acrylic, and its end face in contact with the steel plate remains sharp.

[0009] Preferably, the tolerance of the aluminum pad is controlled within ±1mm.

[0010] Preferably, the powerful magnet is made of 8*10mm thickness specification.

[0011] Preferably, there are four hexagonal socket screws.

[0012] Preferably, the internal hexagon screw is compatible with the cylindrical countersunk hole and the threaded hole.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. In this utility model, the end face of the acrylic motherboard that contacts the steel plate is set to a right angle and is not chamfered, which ensures the sharpness of the end face. Combined with a strong magnet, the fixture is pressed tightly against the steel plate. The cooperation between the two can smoothly and thoroughly scrape off the excess ink on the steel plate, thus improving the ink removal effect.

[0015] 2. In this utility model, by controlling the tolerance of the aluminum pad within ±1mm and adjusting its width during assembly, and by using acrylic and aluminum materials, the problem of damage to the pad printing steel plate due to unsuitable width or excessively hard material of the aluminum pad is avoided, thus extending the service life of the pad printing steel plate and ensuring the smooth progress of the ink application process.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a 3D curved glass pad printing ink removal assembly fixture, including an acrylic main board 1, an aluminum pad 2, and a hexagonal screw 3. The top of the acrylic main board 1 has seven filling holes 11, and the filling holes 11 are filled with strong magnets. The acrylic main board 1 is connected to the aluminum pad 2 through the hexagonal screw 3. The hexagonal screw 3 is of M5*16mm specification. The aluminum pad 2 has two threaded holes 21. The aluminum pad 2 is made of aluminum alloy A6061. The acrylic main board 1 has a cylindrical countersunk hole 12. The hexagonal screw 3 passes through the cylindrical countersunk hole 12 and connects to the threaded hole 21 on the aluminum pad 2. The end face of the acrylic main board 1 that contacts the steel plate is right angled and has no chamfer.

[0024] like Figure 3 As shown, the main body of the acrylic motherboard 1 is made of acrylic, and its end face that contacts the steel plate remains sharp. This design ensures that during the ink application process, the end face can accurately cut into the excess ink layer, reduce ink residue, and improve the thoroughness of ink removal.

[0025] like Figure 4 As shown, the tolerance of the aluminum pad 2 is controlled within ±1mm. This tolerance range can ensure that the overall width of the aluminum pad 2 and the acrylic motherboard 1 after assembly is adapted to the working space of the pad printing steel plate, and avoid ink obstruction or scratching of the steel plate due to dimensional deviation.

[0026] like Figure 2 As shown, the powerful magnet uses With a thickness of 8*10mm, the magnets of this specification provide a stable attraction force, allowing the end face of the acrylic mainboard 1 to fit tightly against the surface of the pad printing steel plate, preventing ink residue from forming due to gaps during operation.

[0027] like Figure 1 As shown, there are four internal hex screws 3. The four screws are symmetrically distributed at the connection positions of the acrylic main board 1 and the aluminum pad 2, which can evenly distribute the assembly stress and prevent the parts from deforming due to uneven force.

[0028] like Figure 2 As shown, the internal hex screw 3 is compatible with the cylindrical countersunk hole 12 and the threaded hole 21. The compatible size ensures that the screw is firmly connected and prevents loosening during operation. At the same time, the cylindrical countersunk hole 12 can accommodate the screw head and avoid the head protruding and affecting the fit between the fixture and the steel plate.

[0029] The usage and working principle of this device are as follows: Before use, check whether the end face of the acrylic main board 1 that contacts the steel plate is sharp and without chamfers, and whether the width of the aluminum pad 2 is within a suitable range. Place the end face of the fixture that contacts the steel plate flat on the pad printing steel plate. The fixture is made to stick tightly to the surface of the steel plate by the attraction force of the strong magnet in the filling hole 11. After confirming that the fit is tight, slowly push the fixture along the surface of the steel plate. During the process, observe the scraping of excess ink. After the operation is completed, wipe the ink remaining on the end face of the fixture with a lint-free cloth and place it in a dry and dust-free environment for later use.

[0030] During the 3D curved glass pad printing process, when excess ink remains on the printing plate, this fixture, through the sharp right-angle structure of the acrylic main board 1 end face, can cut into the ink layer like a scraper. During the pushing process, it peels the excess ink off the surface of the plate. The strong magnet inside the filling hole 11 generates an adsorption force that keeps the fixture tightly attached to the plate, preventing ink residue or ink trajectory deviation due to gaps. The aluminum pad 2 provides a stable support height for the fixture through precise tolerance control, ensuring that the end face of the acrylic main board 1 maintains the optimal contact angle with the plate surface. At the same time, the aluminum alloy A6061 material has both strength and toughness, which can reduce wear when in contact with the plate. The hexagonal screw 3, through the matching connection with the countersunk hole 12 and the threaded hole 21, firmly assembles the acrylic main board 1 and the aluminum pad 2 into a whole, ensuring that the components do not shift relative to each other during operation, thereby achieving continuous and stable ink removal operation, and ultimately achieving the purpose of removing excess ink and ensuring the quality of subsequent pad printing.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
