Description

Technical Field

[0001] This utility model relates to the field of adhesive pad mounting plate technology, and in particular to an adhesive pad mounting plate for 3D curved glass pad printing. Background Technology

[0002] In the field of 3D curved glass processing, pad printing is a crucial step in achieving precise transfer of patterns and markings on the glass surface. With the surge in demand for 3D curved glass in consumer electronics (such as mobile phones and smart wearable devices), pad printing operations need to adapt to complex curved surfaces and high-precision pattern transfer, placing increasingly stringent requirements on the stability and accuracy of the pad printing head. As the core component connecting the pad printing head to the pad printing machine, the design and performance of the pad printing head mounting plate directly affect the yield rate and production efficiency, driving the industry to develop more reliable and adaptable pad printing head mounting plates.

[0003] The grooves of existing pad printing plates for 3D curved glass are often poorly designed (e.g., the fit gap is too large or too small). The pads are prone to displacement under printing pressure (leading to pattern misalignment) or excessive compression deformation (affecting ink transfer). The yield rate is less than 70%. The groove size is fixed and cannot be compatible with pad printing pads of different diameters and shapes (e.g., round or irregularly shaped pads). The mounting holes and the interface of the pad printing machine are not standardized. When changing models, it is necessary to re-drill holes or modify them, resulting in high adaptation costs and long cycles. Utility Model Content

[0004] This utility model mainly provides a glue head mounting plate for 3D curved glass pad printing to improve yield.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pad mounting plate for D-curved glass pad printing, comprising: a mounting plate body, wherein a pad groove is provided on the top of the mounting plate body, mounting holes are provided on the surface of the mounting plate body and near the four corners, and circular holes are symmetrically provided on the bottom inner wall of the pad groove.

[0006] Preferably, both ends of the rubber head groove are arc-shaped, and the four corners of the rubber head groove are rounded. With the above settings, the rubber head can be embedded.

[0007] Preferably, each of the mounting holes is embedded with and fixedly connected to a fixing cylinder. Through the above arrangement, it can serve as a fastener that can be adapted to different pad printing machines, achieving the effect of "one machine for multiple uses".

[0008] Preferably, the four corners of the mounting plate body are rounded, which can prevent sharp corners from accidentally injuring workers.

[0009] Preferably, the width of the mounting plate body is 140mm and the length of the mounting plate body is 220mm. The above settings can effectively limit the width and length of the mounting plate body.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, the glue head groove is "custom-designed and matched with the size" according to the outer diameter of the glue head, which not only prevents the glue head from loosening and shifting, but also prevents excessive compression and deformation. With the structure of arc-shaped ends and rounded corners, it can adapt to the irregular shape of the glue head of 3D curved glass, which can reduce the deviation of the pad printing pattern and thus improve the yield rate.

[0012] 2. In this utility model, the mounting hole is embedded with a fixing cylinder, which can be adapted to the fasteners of different pad printing machines, realizing "one machine for multiple uses". The arc and rounded corner design of the glue head groove is compatible with round and irregularly shaped glue heads. The pad printing process can be switched without changing the mounting plate, which can improve the changeover time.

[0013] 3. In this utility model, the rounded corners of the mounting plate and the round holes on the surface serve as "optical positioning marks". When used in conjunction with the CCD vision system of the pad printing machine, the X / Y axis position can be automatically identified and calibrated, reducing the debugging time to 1-2 minutes and greatly improving the production efficiency of small batch orders.

[0017] 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.

[0018] 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.

[0019] Please see Figures 1-2This utility model provides a technical solution: a 3D curved glass pad printing pad mounting plate, comprising: a mounting plate body 1, a pad groove 2 on the top of the mounting plate body 1, mounting holes 3 on the surface of the mounting plate body 1 near the four corners, and symmetrical round holes 5 on the bottom inner wall of the pad groove 2. Through the above arrangement, the pad can be embedded in the pad groove 2 for installation and fixation, and the mounting plate body 1 can be installed through the mounting holes 3.

[0020] like Figure 1 As shown, both ends of the rubber head groove 2 are arc-shaped, and the four corners of the rubber head groove 2 are rounded. Through the above settings, the rubber head can be embedded.

[0021] like Figure 2 As shown, each mounting hole 3 has a fixing cylinder 4 embedded and fixedly connected inside. Through the above setting, it can be used as a fastener that can be adapted to different pad printing machines, achieving the effect of "one machine for multiple uses".

[0022] like Figure 1 As shown, the four corners of the mounting plate body 1 are all rounded. This feature can prevent sharp corners from accidentally injuring workers.

[0023] like Figure 2 As shown, the width of the mounting plate body 1 is 140mm and the length of the mounting plate body 1 is 220mm. Through the above settings, the width and length of the mounting plate body 1 can be limited.

[0024] The usage and working principle of this device are as follows: Based on the mounting interface of the pad printing machine's worktable, select the appropriate screws and pass them through the fixing cylinder 4 inside the mounting hole 3 on the mounting plate body 1 to firmly fix the mounting plate to the worktable. The fixing cylinder 4 prevents the screws from directly abrading the mounting plate, ensuring accuracy after repeated disassembly and assembly. For the glue head assembly: Select the corresponding size glue head according to the pad printing requirements and press it down along the arc-shaped guide surface of the glue head groove 2. Utilize the slight interference fit clearance of 0.03-0.05mm between the groove and the glue head to ensure the glue head is securely inserted into the groove. If the glue head has a positioning structure at the bottom, it can be fitted with the round hole 5 at the bottom of the groove, or connected to the negative pressure system of the pad printing machine through the round hole to enhance fixation. At this time, adjust and calibrate the visual positioning. The CCD vision system can be activated through the pad printing machine to identify the four corner features of the mounting plate and the round hole 5 on the surface, generating the coordinate information of the mounting plate on the worktable. The system compares the position of the 3D curved glass to be printed, automatically calculates the deviation, and drives the X / Y axis to adjust the position of the mounting plate, ensuring that the printing head is precisely aligned with the area to be printed on the glass, with the deviation controlled within ±0.1mm. The pad printing machine moves the mounting plate and the printing head, which contacts the ink tray and uses its own elasticity to absorb ink. The arc and rounded corner design of the printing head groove 2 ensures the stability of the printing head shape and guarantees uniform ink absorption. Simultaneously, the pad printing machine controls the movement of the mounting plate, precisely pressing the ink-laden printing head onto the surface of the 3D curved glass. Utilizing the elasticity of the printing head and its adaptability to the curved glass surface, the ink is transferred to the glass, completing the pattern transfer. The AL6061 material of the mounting plate ensures structural rigidity, allowing for uniform pressure transmission from the printing head and improving the printing effect. After a single transfer is completed, the pad printing machine resets the mounting plate, and the printed glass is removed manually or mechanically. A special cleaning agent is used to clean the surface of the mounting plate and the printing head groove 2 to remove residual ink and impurities. The condition of the printing head is checked, and any worn or deformed parts are replaced immediately. Regularly check the mounting holes 3, fixing cylinder 4 and groove accuracy of the mounting plate, and use precision testing equipment to measure dimensional deviations. If they exceed the tolerance range, repair or replace them to ensure the accuracy of subsequent pad printing.

[0025] 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.
