Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of screen printing material taking, and specifically relates to an automatic screen printing material taking production device. Background Technique
[0002] Currently, screen printing refers to using a screen as a printing plate base, and through a photosensitive plate making method, a screen printing plate with patterns and texts is made. Utilizing the basic principle that the mesh holes in the graphic part of the screen printing plate can pass through ink, while the mesh holes in the non-graphic part cannot pass through ink for printing. During printing, ink is poured at one end of the screen printing plate, a squeegee applies a certain pressure to the ink part on the screen printing plate, and at the same time moves uniformly towards the other end of the screen printing plate. The ink is squeezed from the mesh holes in the graphic part onto the printing substrate by the squeegee during the movement; During the working process of existing printing equipment, material taking operations are required. When the existing material taking mechanism takes materials, it can only take materials placed at designated positions, so there are great limitations in the use process. If the placement positions are different, normal material taking cannot be carried out. Moreover, during the printing process, the printing area cannot be detected.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

If the position of the plates placed during the material taking process is misaligned, normal material taking cannot be carried out, or the stability during the material taking process is reduced, resulting in the situation that the plates slide off. And after the material taking is completed, the plates after the material taking are automatically fixed, and the top of the plates is cleaned during the fixing process, avoiding dirt on the top of the plates before printing, resulting in unsuccessful printing. 2. The present invention also uses the cooperation of the detection mechanism and the abnormal identification mechanism. During the printing process of the plate body, the printing area before and during the printing can be detected. When the printing fails or there are abnormalities in the printing area, through the dual processing of air pressure detection and sliding detection, it can be detected in the first time, which can not only increase the sufficiency and comprehensiveness of the detection process, but also conduct quality inspection on the plates, avoiding abnormal problems in the printing area of the plates during the processing, and the abnormal problems are relatively subtle and cannot be found, and the printing operation is still in progress, which will not only reduce the qualification rate and the finished product rate, but also the detection method is relatively single during the detection, and there are still problems of incompleteness and dead angles even during the detection.

One end of the pulling rope 712 away from the moving rod 711 is wound around the outside of the rotating wheel 713. At the top of the rotating wheel 713, a fixed cylinder 715 is installed. Inside the top end of the fixed cylinder 715, an installation top rod 714 is slidably installed. The bottom ends of the fixed cylinder 715 and the installation top rod 714 are both rectangular structures when viewed from above. At the bottom end of the installation top rod 714, a compression spring 716 is installed. At the bottom rear side of the installation top rod 714 and the lower middle part of the rear side of the inner cavity of the fixed cylinder 715, connection guide blocks 717 are both installed. The connection guide blocks 717 are electrically connected to the control panel. At the top of the installation top rod 714, an installation frame rod 704 is installed. At the top of the installation frame rod 704, a number of hook rods 705 are equidistantly installed. The hook rods 705 are all arc-shaped structures. At the top of the installation frame rod 704 and at the bottom ends of the hook rods 705, movable guide grooves 719 are opened. On one side of the inner cavity of the movable guide grooves 719, installation bumps 720 are slidably installed. The top ends of the installation bumps 720 are connected to the bottom ends of the hook rods 705. On one side of the inner cavity of the movable guide grooves 719, tension springs 721 are installed.

The trigger touch switches 718 are electrically connected to the control panel. The hook rods 705 are made of rubber material; The specific implementation method is as follows: After the board is fixed between the top ends of the movable platen 9 and the fixed platen 10, start the multi-section electric telescopic rod 702 to drive the movable mounting plate 701 to move upward, drive the suction cup frame 703 to move upward, so that the top end of the suction cup frame 703 contacts the bottom end of the board and is located directly below the printing area. When the movable mounting plate 701 continues to move upward, it will squeeze the suction cup frame 703. At the same time, the top end of the hook rod 705 will also contact the bottom end of the board. Then, drive the mounting frame rod 704 to move downward through the hook rod 705, and drive the mounting top rod 714 to move toward the bottom end of the inner cavity of the fixed cylinder 715, squeezing the compression spring 716. This can not only increase the adhesion between the hook rod 705 and the board, but also drive the mounting top rod 714 and the mounting frame rod 704 to move upward and reset through the compressed compression spring 716 in the later stage. When there is a bulge abnormality in the printing area of the board, the mounting top rod 714 will move downward a longer distance, causing the two connecting guide blocks 717 to contact each other, and then start the alarm on the control panel to give an alarm. When squeezing the suction cup frame 703, the air inside the suction cup frame 703 is squeezed into the inner part of the shrinkage sleeve 707 during the squeezing process, causing the shrinkage sleeve 707 to expand and drive the movable top block 708 to move inside the moving notch 706, so that the movable top block 708 contacts the pressure control switch 709. The pressure value generated by the pressure control switch 709 is fed back to the control panel. If there is an abnormality in the board in the printing area, the air pressure inside the suction cup frame 703 will be abnormal, so that the shrinkage sleeve 707 cannot expand, and the pressure control switch 709 cannot be triggered or the value generated by squeezing the pressure control switch 709 cannot reach the preset value in advance, then the control panel will be triggered to give an alarm. When the movable top block 708 moves, it drives the movable rod 711 to move inside the moving long slot 710 and drives the pulling rope 712 to move. The movement of the pulling rope 712 drives the rotating wheel 713 to rotate. The rotating wheel 713 drives the fixed cylinder 715 to rotate, which drives the mounting top rod 714 to rotate, and drives the mounting frame rod 704 and the hook rod 705 to rotate, so that the top end of the hook rod 705 slides and rubs against the printing area of the bottom plate of the board. If there is an abnormality in the printing area, the resistance generated by the hook rod 705 will become larger, driving the mounting convex block 720 to slide inside the movable guide groove 719 and stretching the tension spring 721, so that the mounting convex block 720 contacts the trigger touch switch 718 and triggers the control panel to give an alarm.
[0023] The device further includes an abnormal identification mechanism 8, which includes a storage notch 801, a fixed support plate 802, an extrusion airbag 803, a movable support plate 804, a storage sleeve 805, a connecting pipe 806, a stable slide rail 807 and a stable slide bar 808.

The bottom end of the stable slide bar 808 is slidably connected to the bottom end of the inner cavity of the stable slide rail 807. Storage notches 801 are formed on the front side and the rear side of the inner cavity of the movable mounting plate 701. Solenoid valves 809 are formed on the front side and the rear side of the bottom end of the inner cavity of the suction cup frame 703.

Connecting holes are formed at the bottom end of the inner cavity of the storage notch 801. Pigment is added to the inner cavity of the storage notch 801, and air holes are formed inside the movable support plate 804; The specific implementation method is as follows: When the movable mounting plate 701 moves upward, it drives the connecting pipe 806 and the movable support plate 804 to move upward, squeezes the extrusion airbag 803, and conveys the air inside the extrusion airbag 803 to the inside of the storage notch 801 through the connecting pipe 806, and then conveys the air to the inside of the storage sleeve 805, causing the storage sleeve 805 to expand. When an abnormality is found during the detection process, the solenoid valve 809 is activated to relieve the pressure inside the storage notch 801, so that the air pressure inside the storage sleeve 805 loses its restraint, and the air pressure inside the storage sleeve 805 is conveyed to the inside of the storage notch 801. When the air pressure inside the storage notch 801 becomes larger, the pigment inside the storage notch 801 is conveyed to the inside of the solenoid valve 809, and the raw material is sprayed to the abnormal area of the plate through the solenoid valve 809 for identification. And when the movable mounting plate 701 moves, it drives the stable slide bar 808 to slide inside the stable slide rail 807, increasing the stability and flexibility of the movable mounting plate 701 when it moves.
[0024] Working principle: When the present invention performs printing and material taking, first start the multi-section electric push rod 308 to drive the monitoring frame 311 to move upward, and drive the electric conveyor belt 301 to move upward, so that the electric conveyor belt 301 moves to the upper end of the inner cavity of the moving through groove 312. When there are differences in the material taking positions, start the servo motor 307 to drive the moving screw 304 to rotate inside the moving slide rail 303, drive the moving slider 305 to move inside the moving slide rail 303, and drive the horizontal moving machine rail 309 to move horizontally, then drive the monitoring frame 311 and the electric conveyor belt 301 to move. When performing horizontal movement, start the horizontal moving machine rail 309 to drive the monitoring frame 311 and the electric conveyor belt 301 to move horizontally. When the electric conveyor belt 301 moves towards the movable platen 9, it will push the movable platen 9 to move on the upper end of the working frame 2, drive the mounting slide rail 502 to slide outside the mounting slider 504, and squeeze the return spring 503. Later, drive the movable platen 9 to reset through the squeezed return spring 503. When performing printing work, start the electric moving rail 402 to drive the movable mounting plate 403 and the fixed strip 404 to move. When the working machine frame 401 drives the electric moving rail 402 to move downward, drive the fixed strip 403 to move downward, and drive the limiting strip 405 to move downward through the mounting slide rod 407, so that the bottom end of the limiting strip 405 contacts the top end of the plate. When the fixed strip 404 continues to move downward, make the sliding hole slide outside the mounting slide rod 407 and stretch the mounting spring 408, and then start the working head 406 to perform printing operations; After the material taking of the plate is completed, when the horizontal moving machine rail 309 resets and moves, drive the push-pull plate 506 to move backward through the fixed cross plate 310, and squeeze the shrinkable airbag 507. Send the air inside the shrinkable airbag 507 to the inside of the fixed limiting plate 505 through the connecting air pipe 508, and send the air to the outside of the fixed limiting plate 505 through the air holes to form an air flow to contact and clean the upper end of the plate. Then start the single-phase motor 515 to drive the movable screw 514 to rotate inside the movable chute 512, drive the movable slider 513 to slide inside the movable chute 512, and drive the movable limiting plate 501 to move through the moving strip plate 509, so that the movable limiting plate 501 contacts and fixes the plate. When the moving strip plate 509 moves, squeeze the push-pull airbag 511, and send the air inside the push-pull airbag 511 to the inside of the limiting airbag 510 through the air holes, so that the limiting airbag 510 expands and contacts and wraps the front side of the plate body for limiting, increasing the efficiency during limiting and fixing; After the sheet is fixed between the top ends of the movable platen 9 and the fixed platen 10, start the multi-section electric telescopic rod 702 to drive the movable mounting plate 701 to move upward, drive the suction cup frame 703 to move upward, so that the top end of the suction cup frame 703 contacts the bottom end of the sheet and is directly below the printing area. When the movable mounting plate 701 continues to move upward, it will squeeze the suction cup frame 703. At the same time, the top end of the hook rod 705 will also contact the bottom end of the sheet. Then, the hook rod 705 drives the mounting frame rod 704 to move downward and drives the mounting top rod 714 to move toward the bottom end of the inner cavity of the fixed cylinder 715, squeezing the compression spring 716. This can not only increase the adhesion between the hook rod 705 and the sheet, but also drive the mounting top rod 714 and the mounting frame rod 704 to move upward and reset by the compressed compression spring 716 in the later stage. When there is an abnormal protrusion in the printing area of the sheet, the mounting top rod 714 will move downward a longer distance, causing the two connecting guide blocks 717 to contact each other, and then the alarm on the control panel will be activated for alarm. When squeezing the suction cup frame 703, the air inside the suction cup frame 703 is squeezed into the shrinkage sleeve 707 during the squeezing process, causing the shrinkage sleeve 707 to expand and drive the movable top block 708 to move inside the moving notch 706, so that the movable top block 708 contacts the pressure control switch 709. The pressure value generated by the pressure control switch 709 is fed back to the control panel. If there is an abnormality in the sheet in the printing area, the air pressure inside the suction cup frame 703 will be abnormal, so that the shrinkage sleeve 707 cannot expand, and the pressure control switch 709 cannot be triggered or the value generated by squeezing the pressure control switch 709 cannot reach the preset value in advance, triggering the control panel to alarm. When the movable top block 708 moves, it drives the movable rod 711 to move inside the moving long slot 710 and drives the pulling rope 712 to move. The movement of the pulling rope 712 drives the rotating wheel 713 to rotate. The rotating wheel 713 drives the fixed cylinder 715 to rotate, driving the mounting top rod 714 to rotate, and driving the mounting frame rod 704 and the hook rod 705 to rotate, so that the top end of the hook rod 705 slides and rubs against the printing area at the bottom end of the sheet body. If there is an abnormality in the printing area, the resistance generated by the hook rod 705 will increase, driving the mounting convex block 720 to slide inside the movable guide groove 719 and stretching the tension spring 721, so that the mounting convex block 720 contacts the trigger touch switch 718 and triggers the control panel to alarm.
