Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, specifically a screen printing glass plate reversal device. Background Technology

[0002] Screen printing is a stencil printing technique that uses a screen as a printing plate base. A screen printing plate with images and text is created through a photosensitive plate-making method. Currently, in the production of photovoltaic rolled glass, due to differences in product varieties, some require more processing steps. Besides coating the front side (the textured side) of the glass sheet, it also requires processing the back side, such as screen printing. Furthermore, due to differences in user processing techniques, some users have specific requirements for the stacking of glass sheets, such as front-side up or back-side up. This necessitates that glass sheet manufacturers perform reverse processing on the glass sheets during production or to meet user needs.

[0003] Chinese Patent Publication No. CN213622240U discloses a screen-printed glass sheet reversing device. A set of reversing wheels is installed between two glass conveying rollers operating in opposite directions. A pair of leaf-shaped reversing inserts are mounted on the reversing wheels. When the glass is conveyed to the reversing position, rotating the reversing wheels causes the glass to slowly rotate under the influence of the reversing inserts until it reaches the reverse glass conveying roller after a 180-degree rotation. The entire process is safe and stable, without damaging the glass, meeting the needs of screen printing technology and satisfying users' special process requirements. The device features overall automatic control, reducing labor intensity and improving efficiency.

[0004] While the aforementioned patent can reverse glass plates, it requires manual adjustment of the spacing between the reversing wheels and the blade spacing when dealing with glass plates of different sizes or thicknesses. If the number of glass plates of the same size to be reversed each time is small, the staff needs to frequently adjust the spacing between the reversing wheels and the blade spacing, which not only wastes time and leads to low work efficiency, but also increases the labor intensity of the staff. Utility Model Content

[0005] The purpose of this invention is to provide a screen-printed glass plate reversal device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A screen-printed glass plate reversal device includes:

[0008] The frame has multiple conveying mechanisms evenly spaced at both ends inside the frame;

[0009] A flipping mechanism is located in the middle of the frame and between the conveying mechanisms at both ends of the frame. It can flip the glass plate. The flipping mechanism includes a circular roller that rotates between two opposite sides inside the frame. The outer wall of the circular roller is fixedly connected with a plurality of fixing components for fixing the glass plate along its length and at equal angles in a ring.

[0010] The venting mechanism, located on one side of the frame, is capable of venting multiple fixed components.

[0011] Furthermore, both ends of the outer wall of the roller are fixedly connected to a hollow turntable. The fixing assembly includes a connecting pipe fixedly connected to the outer wall of the roller. One end of the connecting pipe is fixedly connected to a fixing shell. Both ends of one side of the fixing shell are fixedly connected to fixing rods. An airbag column is fixedly connected to the outer wall of the fixing rod. An air hole is opened on the outer wall of the fixing rod.

[0012] Furthermore, a conduit is fixedly connected at an equal angle between the two turntables, and a plurality of connecting pipes at corresponding positions are fixedly connected through it. One end of the conduit passes through the turntable at the corresponding position and is located inside the turntable. The other end of the conduit passes through the other turntable and is located outside the turntable. A plurality of sealing elements for sealing the conduit at the corresponding position are provided at an equal angle on the side of the other turntable.

[0013] Furthermore, a one-way valve is fixedly connected to the outer wall of the duct near one of the turntables, and an air inlet pipe that is rotatably connected to the frame is fixedly connected through the center of the side of one of the turntables.

[0014] Furthermore, a gear is fixedly connected to the outer wall of the air intake pipe, a motor is fixedly connected to the side of the frame, and the output end of the motor passes through the side of the frame and is fixedly connected to a gear that meshes with the gear.

[0015] Furthermore, the sealing component includes two symmetrically arranged guide rods fixedly connected to the side of another turntable. A plug block that is sleeved on the end of the conduit at the corresponding position slides through the two guide rods at opposite positions. Springs are fixedly connected to the two ends of the plug block and to the outside of the guide rods at the corresponding positions.

[0016] Furthermore, a magnet is embedded and fixed on one side of the block, the venting mechanism includes a connecting plate, both ends of the connecting plate are fixedly connected to a pin that slides through the frame, one end of the pin is embedded and fixedly connected to a magnet that attracts the magnet at the corresponding position, and an electric push rod is fixedly connected between one side of the connecting plate and the frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By inflating multiple fixing components, the glass plates can be automatically fixed. Since multiple fixing components are evenly spaced at the same horizontal height, it is not necessary to adjust the spacing between two adjacent fixing components at the same height when reversing glass plates of different sizes. This improves the efficiency of glass plate reversal and reduces the labor intensity of workers. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 - Figure 5In this embodiment of the present invention, a screen-printed glass plate reversing device includes a frame 1. Multiple conveying mechanisms 11 are equally spaced at both ends of the frame 1. A flipping mechanism 2 capable of reversing the glass plate is provided inside the frame 1 and between the conveying mechanisms 11 at both ends of the frame 1. The flipping mechanism 2 includes a circular roller that rotates between two opposite sides inside the frame 1. Multiple fixing components for fixing the glass plate are fixedly connected along the length direction of the circular roller at equal angles in a ring. A venting mechanism 3 capable of venting the multiple fixing components is provided on one side of the frame 1.

[0027] Specifically, the glass sheet is first conveyed by multiple conveying mechanisms 11 on both sides of the frame 1. When the glass sheet moves towards the center of the frame 1 and is inserted into multiple fixing components at the corresponding positions, an external air pump inflates the fixing components, causing them to clamp and fix the glass sheet. Then, the glass sheet moves upward by rotating the rollers. The multiple fixing components located below the clamped glass sheet are positioned between the multiple conveying mechanisms 11 at the same end until the glass sheet enters between these fixing components. Then, the clamped glass sheet moves to multiple conveyors at the other end by rotating the rollers. On structure 11, the multiple fixed components located in the horizontal direction are depressurized by the depressurization mechanism 3, so that multiple conveying mechanisms 11 at one end can move the glass plate between the multiple fixed components, while multiple conveying mechanisms 11 at the other end remove the glass plate between the multiple fixed components. This device can automatically fix the glass plate by inflating multiple fixed components. Moreover, multiple fixed components at the same horizontal height are equally spaced. Therefore, when reversing glass plates of different sizes, it is not necessary to adjust the spacing between two adjacent fixed components at the same height, thereby improving the efficiency of glass plate reversal and reducing the labor intensity of workers.

[0028] Example 1

[0029] like Figure 3As shown, in this embodiment, hollow turntables 21 are fixedly connected to both ends of the outer wall of the roller. The fixing assembly includes a connecting pipe 22 fixedly connected to the outer wall of the roller. A fixing shell 23 is fixedly connected to one end of the connecting pipe 22. Fixing rods are fixedly connected to both ends of one side of the fixing shell 23. An airbag column 24 is fixedly connected to the outer wall of the fixing rod. Air holes are opened on the outer wall of the fixing rod. A conduit 25 is fixedly connected at an equal angle between the two turntables 21. The conduit 25 passes through and is fixed to multiple connecting pipes 22 at corresponding positions. One end of the conduit 25 passes through the turntable 21 at the corresponding position and is located inside the turntable 21. The other end of the conduit 25 passes through another turntable 21 and is located on the outside of the turntable 21. The side of the other turntable 21 is provided with a plurality of sealing elements at equal angles to seal the conduit 25 at the corresponding positions. A one-way valve 26 is fixedly connected to the outer wall of the conduit 25 near one of the turntables 21. An air inlet pipe that is rotatably connected to the frame 1 passes through and is fixed at the center of the side of one of the turntables 21. A gear 27 is fixedly connected to the outer wall of the air inlet pipe. A motor 28 is fixedly connected to the side of the frame 1. The output end of the motor 28 passes through the side of the frame 1 and is fixedly connected to a gear 2 that meshes with the gear 27.

[0030] In this embodiment, an external air pump is used to inflate the air inlet pipe (the external air pump can be connected to the air inlet pipe via a rotary joint), which inflates multiple airbag columns 24. The inflated airbag columns 24 can then fix the glass plate. Then, the motor 28 drives the roller to rotate, causing the glass plate to rotate along the axis of the roller. When the fixed glass plate moves to the multiple conveying mechanisms 11 at the other end, the degassing mechanism 3 releases the gas from the multiple airbag columns 24 in the horizontal direction (while the multiple airbag columns 24 in the vertical or inclined state remain in an inflated state under the action of the one-way valve 26). At this time, the fixed glass plate is conveyed away by the multiple conveying mechanisms 11 at the other end, while the multiple conveying mechanisms 11 at one end move the glass plate here to the multiple airbag columns 24 at the corresponding position, and then continue to inflate the multiple airbag columns 24 until the multiple airbag columns 24 fix the glass plate here, thereby realizing the clamping and releasing of the glass plate.

[0031] Example 2

[0032] like Figure 4 and Figure 5As shown, in this embodiment, the sealing component includes two symmetrically arranged guide rods 29 fixedly connected to the side of another turntable 21. A plug block 291, which is sleeved on the end of the conduit 25 at the corresponding position, slides through the two guide rods 29 at opposite positions. Springs 292 are fixedly connected to the two ends of the plug block 291 and the outer side of the guide rods 29 at the corresponding positions. A magnet 293 is embedded and fixedly fixed on one side of the plug block 291. The venting mechanism 3 includes a connecting plate 31. Insert pins 32 that slide through the frame 1 are fixedly connected to both ends of the connecting plate 31. A magnet 33 that attracts the magnet 293 at the corresponding position is embedded and fixedly fixed at one end of the insert pin 32. An electric push rod 34 is fixedly connected between one side of the connecting plate 31 and the frame 1.

[0033] In this embodiment, the electric push rod 34 drives the two inserts 32 to move towards the corresponding block 291, causing magnet 293 to attract magnet 33. Then, the electric push rod 34 drives the two blocks 291 at the horizontal position to detach from the corresponding conduit 25, thereby releasing the gas in the multiple airbag columns 24 at the horizontal position. This facilitates the multiple conveying mechanisms 11 at one end to convey the glass plate between the multiple airbag columns 24 at the corresponding position, while the multiple conveying mechanisms 11 at the other end convey the glass plate away from the multiple airbag columns 24 at the corresponding position.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
