Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for glass sheet processing, and more specifically, to a small-sized glass deep hole printing fixture. Background Technology

[0002] In the production and processing of glass sheets used to make mobile phone cameras, screen printing is generally used. The existing processes are divided into single-sheet printing and full-plate printing. Single-sheet printing has low production capacity and is prone to dirt generation during the printing process. The fixtures used in current full-plate printing are generally made of epoxy board, bakelite and other materials, which are prone to deformation during the printing process or the baking process after printing and are difficult to recover, resulting in printing size deviations, affecting product quality. The fixtures also have a short service life. Currently, full-plate printing can only print a maximum of 10 glass sheets at a time, which is inefficient.

[0003] In practical use, when printing on deep holes on the surface of a glass slide, the ink cannot fully contact the inner surface of the deep hole, affecting the overall printing of the ink on the deep hole of the glass slide and reducing the printing efficiency of the ink on the deep hole. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a small-sized glass deep hole printing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A small-sized glass deep-hole printing fixture includes a placement plate, a base frame fixedly connected to the bottom of the placement plate, a positioning template on the top of the placement plate, multiple guide grooves on the upper surface of the placement plate, and an auxiliary printing mechanism on the outer side of the positioning template. The auxiliary printing mechanism includes a sealing strip, the bottom of which is fixedly connected to the bottom of the positioning template. Multiple placement holes are formed on the inner side of the positioning template, and three washers are fixedly connected to the inner side of each placement hole. Multiple rubber rings are fixedly connected to the lower surface of the positioning template. The inner side of the placement plate... The device has multiple air inlets. A base frame is fixedly connected to the bottom of the placement plate. Two air pumps are fixedly connected to the lower surface of the placement plate. An air intake pipe is fixedly connected to the input end of each air pump. A connecting box is fixedly connected to one end of each air intake pipe. Three air intake pipes are fixedly connected to the outside of the connecting box. One end of each air intake pipe passes through the inside of the base frame and is connected to the inside of the base frame. A storage box is slidably connected to the inside of the storage box. Multiple air inlets are provided inside the storage box. A sealing strip is fixedly connected to the top of the storage box. A guide mechanism is provided on the outside of the positioning template.

[0007] By adopting the above technical solution: using two air pumps, suction pipe one, connecting box and suction pipe two to continuously output the air inside the storage box to the outside, maintaining a certain negative pressure adsorption effect at the bottom of the deep hole of the fixed glass plate, so that the ink can fully contact the deep hole inside the glass plate and maintain the full coverage of the printing in the deep hole of the glass plate.

[0008] As a further description of the above technical solution: the guiding mechanism includes multiple support arms, one side of which is rotatably connected to the outside of the positioning template, and one end of which is rotatably connected to a roller. Multiple brackets are fixedly connected to the outside of the positioning template. Two support rods are hinged to the outside of the brackets. Support rods are slidably connected to the inside of support rods. Springs are sleeved on the outside of support rods one and two. One end of support rod two is hinged to the inside of the support arm.

[0009] By adopting the above technical solution, the vibration of the positioning template when it is placed on the surface of the placement plate is reduced by using multiple support rods 1 and 2 and springs to provide elastic support for the support arm and rollers, so that the positioning template can be accurately placed on the top of the placement plate, which facilitates subsequent printing operations.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By setting up an auxiliary printing mechanism, compared with the existing technology, the negative pressure environment formed by the air inlet, the storage box, and the bottom frame can form a negative pressure suction channel at the bottom of the deep hole of the glass slide. When printing on the glass slide, the negative pressure can be activated to guide the ink to flow to the bottom of the hole, so that the ink can fully contact the deep hole of the glass slide, thereby improving the overall coverage and efficiency of printing on the deep hole of the glass slide.

[0012] 2. By setting up a guiding mechanism, compared with the existing technology, the placement of the positioning template can be buffered by using the elastically supported support arm and rollers, reducing the impact between the positioning template and the placement plate, keeping the glass sheet stable after placement of the positioning template, and improving the stability of glass sheet printing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The embodiments disclosed in this application are as follows: Figures 1-6The small-sized glass deep hole printing fixture shown includes a placement plate 1, a base frame 2 fixedly connected to the bottom of the placement plate 1, a positioning template 3 set on the top of the placement plate 1, multiple guide grooves 20 formed on the upper surface of the placement plate 1, and an auxiliary printing mechanism set on the outside of the positioning template 3. The auxiliary printing mechanism includes a sealing strip 4, the bottom of which is fixedly connected to the bottom of the positioning template 3. Multiple placement holes 21 are formed on the inner side of the positioning template 3, three washers 6 are fixedly connected to the inner side of the placement holes 21, multiple rubber rings 5 ​​are fixedly connected to the lower surface of the positioning template 3, multiple air inlets 7 are formed on the inner side of the placement plate 1, a base frame 8 is fixedly connected to the bottom of the placement plate 1, and two air pumps 9 are fixedly connected to the lower surface of the placement plate 1. An air suction pipe 10 is fixedly connected to the input end of the air pump 9, and a connecting box 11 is fixedly connected to one end of the air suction pipe 10. Three suction pipes 12 are fixedly connected to the outside. One end of the suction pipe 12 passes through the inside of the bottom frame 8 and is connected to the inside of the bottom frame 8. A storage box 13 is slidably connected to the inside of the bottom frame 8. Multiple air inlets 22 are opened on the inside of the storage box 13. A sealing strip 23 is fixedly connected to the top of the storage box 13. A guide mechanism is set on the outside of the positioning template 3. The edge of the glass sheet is positioned by three washers 6 on the inside of multiple placement holes 21. Two air pumps 9 are used to create a negative pressure environment inside the storage box 13 by passing through the suction pipe 10, the connecting box 11 and the suction pipe 12 through the multiple air inlets 22 on the inside of the storage box 13. The multiple air inlets 7 and the placement holes 21 adsorb the deep holes of the glass sheet by negative pressure, so that the glass sheet in the deep holes can repeatedly enter the inner wall of the deep holes. Excess ink will enter the inside of the storage box 13 for collection.

[0022] Reference Figure 1 , Figure 3 and Figure 6 As shown, the guiding mechanism includes multiple support arms 14. One side of each support arm 14 is rotatably connected to the outside of the positioning template 3. One end of each support arm 14 is rotatably connected to a roller 15. Multiple brackets 16 are fixedly connected to the outside of the positioning template 3. Two support rods 17 are hinged to the outside of each bracket 16. Support rods 18 are slidably connected to the inside of support rods 17. Springs 19 are sleeved on the outside of support rods 17 and 18. One end of support rod 18 is hinged to the inside of support arm 14. Multiple springs 19 are used to pull support rods 17 and 18 to extend and retract, so that multiple support arms 14 and rollers 15 can roll and guide multiple guide grooves 20 on the top of the placement plate 1. This reduces the impact of the positioning template 3 on the placement plate 1 and maintains the stability of the positioning template 3 after it is positioned with the glass.

[0023] The working principle of this utility model is as follows: When printing deep holes on small-sized glass sheets, multiple glass sheets are first placed sequentially into the multiple placement holes 21 inside the positioning template 3. The three washers 6 inside the placement holes 21 are used to press and position the outer side of the glass sheets. The positioning template 3 with multiple glass sheets is then placed on top of the placement plate 1. The multiple support arms 14 and rollers 15 on the outer side of the positioning template 3 are aligned with the multiple guide grooves 20 on the top of the placement plate 1 and brought closer together. Then, under the weight of the positioning template 3 itself, the multiple support rods 18 and 17 on the outer side of the positioning template 3 will extend and be pulled by the elasticity of the spring 19, so that the positioning template 3 avoids direct collision with the placement plate 1. The sealing strip 4 at the bottom of the positioning template 3 is brought into contact with the upper surface of the placement plate 1, and the multiple rubber rings 5 ​​at the bottom of the positioning template 3 are brought into contact with the upper surface of the placement plate 1. The positions of multiple air inlets 7 on the inner side of the placement plate 1 are aligned and fitted together, so that multiple placement holes 21 and air inlets 7 between the placement plate 1 and the positioning template 3 form a certain sealed space through the double seal of sealing strip 4 and gasket 6. Then, two air pumps 9 are started to suck air from the inner side of the bottom frame 8 through the suction pipe 10, connecting box 11 and three suction pipes 12. The storage box 13 is made into a negative pressure environment through multiple air inlets 22 on the inner side of the storage box 13. Then, when the deep holes on the surface of the glass sheet are printed by the external printing component, the ink inside the deep holes of the glass sheet will enter the interior of the support rod 18 through the placement holes 21 and air inlets 7 in the negative pressure environment inside the storage box 13, so that the ink can fully contact the surface of the deep holes on the inner side of the glass sheet and complete the full printing of the glass sheet.
