Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass processing, in particular to a positioning jig for optical glass silk-screen printing. Background Art
[0002] Optical glass can change the direction of light propagation and alter the relative spectral distribution of ultraviolet, visible, or infrared light. Optical glass can be used to manufacture lenses, prisms, reflectors, and windows in optical instruments. Components made of optical glass are key components in optical instruments.
[0003] Currently, most traditional silk-screen printing on the market mostly adopts single-person single-equipment and single-sheet printing. Most of the jigs used can only place one lens silk-screen pattern at a time. What is particularly important is that the silk-screen pattern will appear heavy, blurred, etc. For this reason, this application discloses a positioning jig for optical glass silk-screen printing. Utility Model Content
[0004] The purpose of the utility model is to solve the existing problems and provide a positioning jig for optical glass silk screen printing.
[0005] The utility model is realized through the following technical solutions: a positioning jig for optical glass silk screen printing, comprising a workbench, a jig body is installed on the workbench, a plurality of clamping holes are arranged in a matrix on the jig body, a through groove is arranged on one side of the clamping hole, a supporting mechanism is arranged in the clamping hole, a screen is movably arranged above the jig body, the screen is tensioned and connected to the frame, and the rear side of the frame is detachably connected to the clamping strip, the two ends of the clamping strip are symmetrically connected to one end of the support rod, and the other end is hinged to the outside of the sliding sleeve of the adjustment mechanism, the pillars of the adjustment mechanism are vertically installed on the workbench, the adjustment mechanisms are connected with a cross bar, a spring is fitted on the cross bar, the two ends of the spring respectively resist the clamping strip and the stop block, and the stop block is arranged on the workbench.
[0006] As a further improvement to the above scheme, the support mechanism includes a support shaft, which is slidably inserted into the hole, with a second spring installed on the support shaft and a support cap connected to the top of the support shaft; the optical glass is supported by the support cap, and the support cap will slide under the gravity of the optical glass and the action of the support cap itself, and the support cap is supported and restricted from sliding downward by the second spring. During silk-screen printing, the screen opens in an arc shape under the action of external force and presses down the glass. When the screen is separated from the glass, the glass rebounds and resets on the support cap by the action of the second spring.
[0007] As a further improvement to the above scheme, the adjustment mechanism includes a pillar, on which spring three is mounted, a sleeve is pressed onto the upper end of spring three, and the sleeve is connected to the pillar via a butterfly nut; the sleeve is mounted on the pillar, and the sleeve is elastically supported by spring three, limited by the butterfly nut, and the height of the sleeve is adjusted by the butterfly nut.
[0008] As a further improvement to the above solution, a gap of 3-5mm is set between the screen and the body to ensure that the screen has tension during the screen printing process and the screen is pressed down. After screen printing, the rebound can avoid blurring, ghosting, and unclear patterns on the glass after screen printing.
[0009] As a further improvement to the above solution, the clamping hole is a tapered hole with a larger upper end and a smaller lower end, which is suitable for supporting optical glasses of different specifications.
[0010] Compared with the existing technology, the utility model has the following advantages: simple structure, reasonable design, novel and unique idea, the height is adjusted by the butterfly nut to leave a gap between the screen plate on the frame and the workpiece body, which is used for the rebound of the screen plate after silk screen printing, avoiding blurred, ghosting, unclear patterns after silk screen printing, etc. In addition, the frame and the screen plate are automatically rotated away from the workpiece body by adjusting the spring between the mechanisms.

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] like Figures 1 to 4 As shown in the figure, a positioning fixture for optical glass silk screen printing includes a workbench 1, on which a fixture body 2 is installed through a supporting claw 3, a plurality of card holes 12 are arranged in a matrix on the fixture body 2, a through groove 13 is arranged on one side of the card hole 12, and a supporting mechanism 14 is arranged in the card hole 12. A screen plate 5 is movably arranged above the fixture body 2, and the screen plate 5 is stretched and connected to the frame 4. The rear side of the frame 4 is detachably connected to the card strip 6. The two ends of the card strip 6 are symmetrically connected to one end of the support rod 7, and the other end is hinged to the outside of the sliding sleeve 83 of the adjustment mechanism 8. The pillar 81 of the adjustment mechanism 8 is vertically installed on the workbench 1, and the adjustment mechanism 8 is connected to a cross bar 11. A spring 10 is installed on the cross bar 11. The two ends of the spring 10 respectively resist the card strip 6 and the stop block 9. The stop block 9 is arranged on the workbench 1.
[0017] As a further improvement to the above scheme, the support mechanism 14 includes a support shaft 16, which is slidably inserted into the hole 18, and a spring 2 17 is installed on the support shaft 16. The top of the support shaft 16 is connected to the support cap 15; the optical glass is supported by the support cap 15, and the support cap 15 will slide under the gravity of the optical glass and the action of the support cap 15 itself, and the support cap 15 is supported and restricted from sliding downward by the spring 2 17. During silk-screen printing, the screen 5 opens in an arc shape under the action of external force and presses down the glass. When the screen 5 is separated from the glass, the glass rebounds and resets on the support cap 15 through the action of the spring 2 17.
[0018] As a further improvement to the above scheme, the adjustment mechanism 8 includes a pillar 81, on which a spring three 82 is mounted, a sleeve 83 is pressed onto the upper end of the spring three 82, and the sleeve 83 is connected to the pillar 81 via a butterfly nut 84; the sleeve 83 is mounted on the pillar 81, and the sleeve 83 is elastically supported by the spring three 82, limited by the butterfly nut 84, and the height of the sleeve 83 is adjusted by the butterfly nut 84.
[0019] As a further improvement to the above scheme, a gap of 3-5 mm is set between the screen plate 5 and the body 2 to ensure that the screen plate 5 has tension during the screen printing process and the screen plate 5 is pressed down after screen printing, so as to avoid blurring, ghosting, and unclear patterns on the glass after screen printing through rebound.
[0020] As a further improvement to the above solution, the clamping hole 12 is a tapered hole with a larger upper end and a smaller lower end, which is suitable for supporting optical glasses of different specifications.
[0021] The working principle of a positioning jig for optical glass silk screen printing is as follows: first, an optical glass disc is placed on the support cap 15 in the clamping hole 12, and the clamping hole 12 on the fixture body 2 is filled. Then, an appropriate amount of silk screen slurry is placed in the frame 4 above the screen 5, and the frame 4 is pressed so that the frame 4 is parallel to the fixture body 2. Then, a rubber scraper is pulled over the screen 5 once to press the screen 5 against the glass. At the same time, the pattern on the screen 5 is printed on the glass surface by the slurry. Without the pressure load of the scraper on the screen 5, the concave arc of the screen 5 rebounds and the screen 5 separates from the glass surface. When the hand does not apply force to the frame 4, the frame 4 rotates under the action of the spring 10 to facilitate the removal of the glass through the through slot 13.
[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
