Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass production technology, and in particular to an automatic screen printing device for round glass covers. Background Technology
[0002] Screen printing on glass covers refers to the process of precisely printing patterns and text onto the glass surface using screen printing technology. This process involves a series of meticulous operations, including screen stretching, ink application, drying, exposure, development, and drying, ultimately ensuring that the ink adheres firmly to the glass, forming a durable pattern. During screen printing, the ink needs to undergo a curing process after being printed onto the glass surface to enhance its adhesion. Screen printing on round glass covers not only requires the precision and clarity of the pattern but also must ensure that there is no ink overflow or accumulation at the edges, which places high demands on the positioning accuracy and stability of the screen printing equipment.
[0003] The current single-mold screen printing equipment has difficulty ensuring the accuracy of product positioning when dealing with screen printing tasks on round glass covers. This directly leads to deviations in the position of the screen-printed pattern, increasing the production of defective products. More seriously, when the product needs to be screen-printed a second time, the glass cover must be manually removed from the equipment and placed back each time. During this process, improper operation can easily cause scratches, damage, or even collisions on the surface of the glass cover, further reducing product quality. Utility Model Content
[0004] The purpose of this invention is to provide an automatic screen printing device for round glass covers, which can automatically complete the entire process of loading, positioning, primary screen printing, secondary screen printing and drying in one go, without the need for manual removal and repositioning, thus effectively improving product quality.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic screen printing device for round-covered glass, comprising a frame, with a feeding belt and a discharging belt respectively provided at both ends of the frame, and an adjustment mechanism, a primary screen printing mechanism, a primary drying mechanism, a secondary screen printing mechanism, and a secondary drying mechanism sequentially arranged along the horizontal direction on the frame, with the adjustment mechanism near the feeding belt and the secondary drying mechanism near the discharging belt, and a positioning plate provided below the primary screen printing mechanism and the secondary screen printing mechanism, and a transfer mechanism provided on the frame, the transfer mechanism comprising a transfer frame that cooperates with the positioning plate, a lifting cylinder fixedly connected to the bottom of the transfer frame, a sliding plate slidably connected in the frame, and a control component for controlling the reciprocating movement of the sliding plate along the horizontal direction.
[0006] By adopting the above technical solution, the feeding belt feeds the round cover glass into the lower part of the adjustment mechanism. The adjustment mechanism adjusts and positions the round cover glass to ensure the accuracy of the positioning. After positioning, the lifting cylinder controls the transfer frame to rise so that the transfer frame contacts the bottom of the round cover glass. The control component controls the sliding plate to move the transfer frame to the lower part of the primary screen printing mechanism. The lifting cylinder controls the transfer frame to fall so that the round cover glass is placed under the primary screen printing mechanism to achieve primary screen printing. After primary screen printing, the transfer frame rises to contact the round cover glass and then moves to the lower part of the primary drying mechanism to achieve primary drying. After primary drying, the transfer frame rises to contact the round cover glass and then moves to the lower part of the secondary screen printing mechanism to achieve secondary screen printing. After secondary screen printing, the transfer frame feeds the round cover glass into the lower part of the secondary drying mechanism to achieve secondary drying. Finally, it is sent out by the unloading belt. In the end, the entire process of loading, positioning, primary screen printing, secondary screen printing and drying is completed automatically in one go without manual removal and repositioning, which effectively improves the product production quality.
[0007] The present invention is further configured as follows: the adjustment mechanism includes an adjustment bracket fixedly connected to the frame, a first rotating rod and a second rotating rod rotatably connected to the adjustment bracket in a horizontal direction, a first motor fixedly connected to the end of the first rotating rod, a second motor fixedly connected to the end of the second rotating rod, a first sliding block symmetrically arranged on the first rotating rod, and a second sliding block symmetrically arranged on the second rotating rod.

The first rotating rod and the second rotating rod are perpendicular to each other. The first rotating rod and the second rotating rod are both provided with threads of the same pitch but opposite directions. The first sliding block is threadedly connected to the first rotating rod, and the second sliding block is threadedly connected to the second rotating rod.

The control component controls the sliding plate to move the transfer frame and the round cover glass to the positioning plate below the primary screen printing mechanism. When the T-shaped plate is aligned with the strip groove, the positioning of the round cover glass is completed. The lifting cylinder controls the long plate to descend, so that the T-shaped plate moves below the positioning plate. At this time, the round cover glass is placed on the positioning plate for primary screen printing. After the primary screen printing is completed, the lifting cylinder controls the long plate to rise, so that the T-shaped plate contacts the round cover glass and detaches the round cover glass from the upper surface of the frame.

A motor 1042 is fixedly connected to the end of the drive rod 1041. The motor 1042 is fixedly connected to the frame 1. The motor 1042 controls the rotation of the drive rod 1041, thereby controlling the sliding plate 103, which is threadedly connected to the drive rod 1041, to reciprocate along its length.

After positioning is completed, the lifting cylinder 102 controls the long plate 1011 to rise. The upper end of the T-shaped plate 1012 contacts the bottom of the round cover glass, causing the round cover glass to detach from the upper surface of the frame 1. The motor 3 1042 controls the drive rod 1041 to rotate, thereby controlling the sliding plate 103 to move the transfer frame 101 and the round cover glass to the positioning plate 9 below the primary screen printing mechanism 5. When the T-shaped plate 1012 is aligned with the strip groove 13, the positioning of the round cover glass is completed. The lifting cylinder 102 controls the long plate 1011 to descend, causing the T-shaped plate 1012 to move below the positioning plate 9. At this time, the round cover glass is placed on the positioning plate 9 for primary screen printing. After the primary screen printing is completed, the lifting cylinder 102 controls the long plate 1011 to rise, causing the T-shaped plate 1012 to align with the bottom of the frame 1. The round cover glass contacts and detaches from the upper surface of the frame 1. The sliding plate 103 moves, driving the transfer frame 101 and the round cover glass to move below the primary drying mechanism 6. When the T-shaped plate 1012 aligns with the strip groove 13, the lifting cylinder 102 controls the long plate 1011 to descend, placing the round cover glass below the primary drying mechanism 6. The two limiting plates 16 restrict and position the round cover glass, achieving primary drying. After primary drying is completed, the lifting cylinder 102 controls the long plate 1011 to rise, causing the T-shaped plate 1012 to contact the round cover glass and detach it from the upper surface of the frame 1. The sliding plate 103 moves, driving the transfer frame 101 and the round cover glass to move to the secondary screen printing... Below mechanism 7, when the T-shaped plate 1012 is aligned with the strip groove 13, the lifting cylinder 102 controls the long plate 1011 to descend, and the round cover glass is placed below the secondary screen printing mechanism 7 for secondary screen printing. After the secondary screen printing is completed, the lifting cylinder 102 controls the long plate 1011 to rise so that the T-shaped plate 1012 contacts the round cover glass and causes the round cover glass to detach from the upper surface of the frame 1. The sliding plate 103 moves to drive the transfer frame 101 and the round cover glass to move into the discharge roller 12. The lifting cylinder 102 controls the long plate 1011 to descend, and the round cover glass is placed in the discharge roller 12 for secondary drying.
