Description

Technical Field

[0001] This utility model belongs to the technical field of display screen processing tools, specifically relating to a jig for inkjet printing on display screen glass sheets. Background Technology

[0002] In the field of inkjet printing on display glass sheets, specialized fixtures are typically required. However, traditional fixtures have several drawbacks. Firstly, they lack sufficient precision in controlling the fit between the glass sheet and the fixture groove, making it difficult to keep dimensional tolerances within a very small range. For example, with a square glass sheet of 20mm side length, the side length accuracy of a conventional fixture groove is difficult to achieve ±0.05mm. The relatively lenient requirement of ±2mm in the actual inkjet printing standard tolerance makes the glass sheet prone to displacement during the inkjet printing process, severely affecting the accuracy of the printing position and thus reducing the product yield. Secondly, static electricity is easily generated during the friction between the glass and the fixture materials. Traditional fixtures lack effective static electricity elimination and protection technologies. The presence of static electricity interferes with the printing quality, causing problems such as blurry or missing prints, thus hindering the improvement of production efficiency and product quality. Utility Model Content

[0003] The purpose of this utility model is to provide a fixture for inkjet printing on display glass sheets, in order to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fixture for inkjet printing on display glass sheets, comprising a fixture body, wherein the surface of the fixture body is provided with a plurality of horizontally arranged placement grooves for placing display glass sheets, the plurality of placement grooves located in the same row are interconnected by vertically arranged pick-up grooves, the pick-up grooves are also formed on the surface of the fixture body, and the depth of the pick-up grooves is greater than the depth of the placement grooves.

[0005] As a preferred embodiment of this utility model, the fixture body is made of acrylic material, and the placement grooves are provided with at least 40.

[0006] In a preferred embodiment of this invention, the width of the taking-up groove is greater than one-third of the width of the placing groove.

[0007] As a preferred embodiment of this utility model, the surface of the fixture body, the placement groove, and the piece-taking groove are all coated with an antistatic coating.

[0008] In a preferred embodiment of this invention, when the display glass sheet is placed inside the placement groove, the top of the display glass sheet is flush with the opening of the placement groove.

[0009] In a preferred embodiment of this invention, the width of the placement groove is 20mm, and the assembly accuracy between the placement groove and the display glass sheet is ±0.05mm.

[0010] As a preferred embodiment of this utility model, the vertically arranged tablet-retrieving groove significantly optimizes the tablet-retrieving process, transforming the tablet-retrieving action from the previous need for careful prying to a simple pinching action, reducing the tablet-retrieving time from an average of 3-5 seconds to 1-2 seconds, and greatly improving operational efficiency.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1) In terms of precision adaptation, the fixture body of the display glass sheet is processed by CNC machining equipment. The width of the placement groove is 20mm, and the assembly accuracy with the display glass sheet can reach ±0.05mm, which is far higher than the actual inkjet standard tolerance. The high-precision adaptation design ensures that the glass sheet and the placement groove are tightly and stably fitted, effectively preventing the displacement of the glass sheet during the inkjet printing process, greatly ensuring the accuracy of the inkjet printing position and improving the product qualification rate.

[0013] 2) Both the placement groove and the pick-up groove of this utility model are coated with an anti-static coating, which effectively solves the problem of static electricity generated by friction between glass and acrylic affecting the coding quality.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a fixture for inkjet printing on display glass sheets, comprising a fixture body 100, wherein the surface of the fixture body 100 is provided with a plurality of horizontally arranged placement grooves 110 for placing display glass sheets, the plurality of placement grooves 110 located in the same row are interconnected by vertically arranged sheet-taking grooves 120, the sheet-taking grooves 120 are also formed on the surface of the fixture body 100, and the depth of the sheet-taking grooves 120 is greater than the depth of the placement grooves 110.

[0023] Specifically, during the inkjet printing process on the display glass, the placement groove 110 of the fixture body 100 provides a stable placement platform for the display glass. Multiple placement grooves 110 can hold multiple glass sheets simultaneously to meet the batch inkjet printing requirements. The placement grooves 110 in the same row are interconnected through vertically set pick-up grooves 120. When the glass sheet is placed in the placement groove 110, during the inkjet printing process, the placement groove 110 plays a lateral limiting role on the glass sheet to prevent it from moving in the horizontal direction. When picking up the glass sheet after inkjet printing, since the pick-up groove 120 is connected to the placement groove 110 and is deeper, the operator can easily pick up the glass sheet from one side of the pick-up groove 120 by a simple pinching action. This avoids the slippage and damage that may be caused by directly prying the glass sheet from the horizontal direction, greatly improving the convenience and safety of picking up the glass sheet, and also improving the efficiency of the entire inkjet printing workflow.

[0024] In this embodiment: the fixture body 100 is made of acrylic material, and the placement groove 110 has at least 40 grooves.

[0025] Specifically, firstly, the CNC machining equipment can perform high-precision cutting and engraving of the acrylic jig body 100, which can meet the precise design requirements of structures such as the placement grooves 110. When printing on display glass sheets, at least 40 placement grooves 110 can make full use of the surface space of the jig body 100, enabling a large number of glass sheets to be loaded for printing at one time, thereby improving production efficiency.

[0026] Acrylic material itself has a relatively uniform texture and is not easily deformed during long-term use. It can always maintain the shape accuracy of the groove 110, ensuring the stability of the glass sheet during placement and coding, ensuring the accuracy of the coding position, thereby improving the product qualification rate. At the same time, the cost is relatively low and the practicality is good.

[0027] In this embodiment, the width of the taking groove 120 is greater than one-third of the width of the placing groove 110.

[0028] Specifically, the width of the glass pick-up groove 120 is one-third greater than the width of the placement groove 110, fully considering the convenience of actual operation. During the glass pick-up process, if the pick-up groove 120 is too narrow, the operator's fingers will have difficulty entering to pinch the glass, increasing the difficulty and time required, and potentially even damaging the glass due to inconvenience. The wider pick-up groove 120 provides sufficient operating space for the operator, making the pinching of the glass easy. At the coding site, after a batch of glass sheets is coding, the operator can quickly and accurately remove the glass sheets from the pick-up groove 120, freeing up space for the placement and coding of the next batch, accelerating the pace of the entire coding process and improving work efficiency.

[0029] In this embodiment, an antistatic coating is applied to the surface of the fixture body 100, the inside of the placement groove 110, and the inside of the piece-taking groove 120.

[0030] Specifically, during the printing process on the display screen glass sheet, after the glass sheet is placed in the placement groove 110, even if the glass sheet rubs against the fixture when the printing equipment performs the printing operation, static electricity cannot accumulate due to the anti-static coating, thus ensuring the stability of the printing environment. During the printing process, the ink can be evenly adhered to the surface of the glass sheet to form clear and complete printed content, improving the overall quality of the product, reducing the defect rate caused by static electricity problems, and improving production efficiency.

[0031] In this embodiment: when the display glass sheet is placed inside the placement groove 110, the top of the display glass sheet is flush with the opening of the placement groove 110.

[0032] Specifically, when the display glass sheet is placed inside the placement groove 110, the inkjet printer needs to precisely align the inkjet head with the surface of the glass sheet to spray ink during the inkjet printing operation. If the top of the glass sheet is higher or lower than the opening of the placement groove 110, the distance between the inkjet head and the surface of the glass sheet will change, thus affecting the clarity and accuracy of the inkjet printing. However, when the top of the glass sheet is flush with the opening of the groove, the inkjet head can print within a relatively stable distance range, ensuring the uniformity and clarity of the inkjet printing. At the same time, during the sheet picking process, the flush design also makes it easier for the operator to accurately judge the position of the glass sheet, making it easier to pick it up from the sheet picking groove 120, thus improving the efficiency and accuracy of sheet picking.

[0033] In this embodiment, the width of the placement groove 110 is 20mm, and the assembly accuracy between the placement groove 110 and the display glass sheet is ±0.05mm.

[0034] Specifically, in the actual production of inkjet printing on display glass sheets, for square glass sheets with a side length of 20mm, the width of the placement groove 110 is designed to be 20mm, and the assembly accuracy with the glass sheet can reach ±0.05mm. This high-precision design is crucial. When placing the glass sheet, it can be tightly embedded in the placement groove 110, and the extremely small tolerance range effectively limits the movement space of the glass sheet within the groove. During the inkjet printing process, even if the inkjet printer vibrates to some extent, the glass sheet will not shift due to the tight fit between the glass sheet and the placement groove 110. This high-precision fit ensures that the inkjet printhead can accurately print at the predetermined position on the glass sheet every time, greatly improving the accuracy of the printing position, reducing the printing deviation caused by glass sheet displacement, thereby improving the product qualification rate and meeting the production requirements for high-precision inkjet printing.

[0035] In this embodiment, the vertically arranged tablet-retrieving groove 120 significantly optimizes the tablet-retrieving process, transforming the tablet-retrieving action from the previous need for careful prying to a simple pinching action, reducing the tablet-retrieving time from an average of 3-5 seconds to 1-2 seconds, and greatly improving operational efficiency.

[0036] Specifically, when retrieving the glass sheet after inkjet printing, the operator only needs to insert their finger into the retrieval groove 120 to easily pinch the glass sheet. Compared with the traditional prying method, this simple pinching action greatly shortens the retrieval time from an average of 3-5 seconds to 1-2 seconds. Especially in large-scale production of display screen glass sheets, the significant reduction in the retrieval time for each glass sheet can significantly improve overall production efficiency. At the same time, the pinching method reduces damage to the glass sheet caused by improper operation, lowers production costs, improves product yield, and meets the needs of modern high-efficiency production.

[0037] 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 way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
