The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0043] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0044] Reference Figures 1 to 13 The plate printing production line according to an embodiment of the present invention includes a conveyor assembly 100, an adjusting mechanism 200, and a printing machine 300. The adjusting mechanism 200 is disposed on the conveyor assembly 100 and is used to rotate and adjust the angular position of the workpiece; the printing machine 300 is disposed on the conveyor assembly 100; wherein the adjusting mechanism 200 and the printing machine 300 are arranged sequentially along the conveying direction of the conveyor assembly 100.

[0045] During production, the workpiece is placed onto the conveyor assembly 100. The conveyor assembly 100 first transports the workpiece to the adjusting mechanism 200. The adjusting mechanism 200 rotates and adjusts the angular position of the workpiece relative to the conveyor assembly 100. Subsequently, the conveyor assembly 100 transports the workpiece from the adjusting mechanism 200 to the printing press 300 for printing. Because the adjusting mechanism 200 is provided, the workpiece is rotated and its angle adjusted before printing, allowing printing to be performed at different angular positions on the workpiece during printing on the printing press 300.

[0046] Specifically, printing press 300 is a screen printing machine. It is conceivable that printing press 300 could also be other types of printing press 300.

[0047] In this embodiment, the adjustment mechanism 200 includes an adjustment frame 210, an adjustment motor 220, and eight rotating wheels 230. The adjustment motor 220 is mounted on the adjustment frame 210, and the rotating wheels 230 are pivotally connected to the adjustment frame 210. The eight rotating wheels 230 enclose a workpiece rotation position, and the adjustment motor 220 drives one of the rotating wheels 230 to rotate. Specifically, the eight rotating wheels 230 are arranged in a ring. After a circular plate-shaped workpiece enters the workpiece rotation position, the adjustment motor 220 drives one of the rotating wheels 230 to rotate, which, in conjunction with the other rotating wheels 230 for limiting the rotation, drives the workpiece to rotate horizontally on the conveyor assembly 100, thereby adjusting the angle of the workpiece. The adjustment method is relatively simple and suitable for circular plate-shaped workpieces. It is conceivable that the number of rotating wheels 230 can also be other numbers, such as three or more, and they can be arranged in a ring. Of course, the rotating wheels 230 can also be arranged in other ways.

[0048] In this embodiment, the adjustment mechanism 200 further includes a position detector 240, which is disposed on the adjustment frame 210 and used to detect the position of the workpiece. The plate printing production line also includes a control host, which is electrically connected to the position detector 240 and the adjustment motor 220. Specifically, the position detector 240 includes a camera 241 and a fiber optic sensor 242. The fiber optic sensor 242 performs optical detection on the surface of the workpiece, and the camera 241 captures the features of the workpiece for positioning, thereby determining whether the workpiece is at a suitable angle, and controlling the adjustment motor 220 to rotate the workpiece through the control host. It is conceivable that the position detector 240 could also be either the camera 241 or the fiber optic sensor 242.

[0049] In this embodiment, the conveying direction of the conveyor assembly 100 is the front-to-back direction. The adjusting frame 210 includes an adjusting worktable 211, two front-to-back adjusting frames 212, two front-to-back adjusting drivers, and two adjusting lifting drivers 213. The front-to-back adjusting frames 212 are movably disposed on the adjusting worktable 211 in the front-to-back direction. The front-to-back adjusting drivers are disposed on the adjusting worktable 211. The two front-to-back adjusting drivers are connected to the two front-to-back adjusting frames 212 in a one-to-one correspondence. The front-to-back adjusting drivers are used to drive the corresponding front-to-back adjusting frames 212 to move back and forth. The adjusting lifting drivers 213 are disposed on the front-to-back adjusting frames 212 in a one-to-one correspondence. The adjusting lifting drivers 213 are provided with a rotating wheel 230 and are used to drive the corresponding rotating wheel 230 to move closer to or away from the conveyor assembly 100 in the vertical direction. The two front-to-back adjusting frames 212 are arranged at intervals.

[0050] In use, the rear-mounted adjustment lifting driver 213 drives the roller 230 on it to move vertically away from the conveyor assembly 100, and the rear-mounted adjustment front-rear driver drives the rear-mounted front-rear adjustment frame 212 to move backward. Then, the conveyor assembly conveys the workpiece forward until the workpiece touches the front roller 230. Then, the rear-mounted adjustment lifting driver 213 drives the roller 230 on it to move vertically closer to the conveyor assembly 100, and the rear-mounted adjustment front-rear driver drives the rear-mounted front-rear adjustment frame 212 to move forward until it touches the workpiece. At this time, the roller 230 rotates around the workpiece, and the adjustment motor 220 drives one of the rollers 230 to rotate, cooperating with the other rollers 230 to drive the workpiece to rotate and adjust the angle. After the workpiece angle adjustment is completed, the forward and backward adjustment driver at the front drives the forward and backward adjustment frame 212 at the front to move forward away from the workpiece, and the adjustment lifting driver 213 at the front drives the roller 230 on it to move vertically away from the conveyor assembly 100, so that the workpiece can continue to be moved to the next process by the conveyor assembly 100. Subsequently, the forward and backward adjustment frame 212 at the front returns to its original position, and the adjustment lifting driver 213 at the front drives the roller 230 on it to move vertically closer to the conveyor assembly 100. The above process is one cycle of workpiece angle adjustment, and the cycle is repeated sequentially when the workpiece is produced continuously. Specifically, the adjustment lifting driver 213 and the forward and backward adjustment driver are electrically connected to the control host.

[0051] Specifically, each adjusting and lifting actuator 213 is equipped with two rotating wheels 230, and the adjusting and lifting actuator 213 is configured as a cylinder. It can be understood that the adjusting and lifting actuator 213 can also be a linear motor.

[0052] Specifically, the front and rear adjustment bracket 212 is slidably mounted on the adjustment worktable 211 via a slide rail slider. It is conceivable that the front and rear adjustment bracket 212 could also be slidably mounted on the adjustment worktable 211 via guide posts and guide sleeves, or roll on the adjustment worktable 211 via rollers and guide grooves.

[0053] Specifically, the adjusting frame 210 also includes two left and right adjusting frames 215 and two left and right adjusting drivers. The left and right adjusting frames 215 are movably mounted on the adjusting worktable 211 in the left and right direction. The left and right adjusting drivers are mounted on the adjusting worktable 211 and are connected to the left and right adjusting frames 215 respectively to drive the left and right adjusting frames 215 to move left and right. The left and right adjusting frames 215 are equipped with rollers 230. The two left and right adjusting frames 215 are respectively placed on the left and right sides of the conveyor assembly 100. Specifically, the left and right adjusting frames 215 are slidably mounted on the adjusting worktable 211 in the left and right direction by means of slide rails and sliders. The left and right adjusting drivers are configured as cylinders, which can drive the left and right adjusting frames 215 to move left and right, so that the rollers 230 located on the left and right adjusting frames 215 can approach and abut against the workpiece, and move away from the workpiece. It is conceivable that the left and right adjusting frames 215 can also be slidably mounted on the adjusting worktable 211 by means of guide posts and guide sleeves, or rolled on the adjusting worktable 211 by means of rollers and guide grooves; the left and right adjusting drivers can also be linear motors, etc.

[0054] Specifically, the left and right adjustment driver is electrically connected to the control host.

[0055] In this embodiment, the adjustment frame 210 includes an adjustment worktable 211, an adjustment base 214, and a worktable drive assembly. The adjustment worktable 211 is movably disposed on the adjustment base 214 and can move back and forth and left and right relative to the adjustment base 214. The worktable drive assembly is disposed between the adjustment base 214 and the adjustment worktable 211, and is connected to the adjustment worktable 211 to drive the adjustment worktable 211 to move back and forth and left and right relative to the adjustment base 214. Specifically, the position detector 240 is mounted on the adjustment base 214. The ability of the adjustment worktable 211 to move back and forth and left and right relative to the adjustment base 214 facilitates the position detector 240 to detect the workpiece for precise positioning, and the worktable drive assembly precisely adjusts the position of the workpiece.

[0056] Specifically, the workbench drive assembly is electrically connected to the control host.

[0057] Optionally, the worktable drive assembly includes two worktable drive motors, two lead screws, and two lead screw nuts. The output shafts of the worktable drive motors are connected to the lead screws one-to-one. One lead screw is positioned forward and backward, and the other lead screw is positioned left and right. A connecting plate is provided between the two lead screws. The connecting plate can be slidably mounted on the adjusting base 214 via a slide rail slider. The connecting plate is provided with a lead screw nut. One lead screw and the worktable drive motor are mounted on the adjusting base 214 and drive the connecting plate to move via the lead screw nut. The adjusting worktable 211 can be slidably mounted on the connecting plate via a slide rail slider. The other lead screw and the worktable drive motor are mounted on the connecting plate, and the other lead screw nut is mounted on the adjusting worktable 211, thereby realizing the forward and backward and left and right movement of the adjusting worktable 211.

[0058] It is conceivable that the connecting plate could also be slidably connected to the adjusting worktable 211 and the adjusting base via guide posts and guide sleeves, and driven by two linear motors to move forward and backward and left and right respectively. Alternatively, the worktable drive assembly could consist of rollers and two motors, with one motor driving the rollers to rotate and the other motor driving the rollers to turn.

[0059] Specifically, the worktable drive assembly also includes a third motor for fine-tuning the angle of the worktable 211 relative to the adjustment base 214.

[0060] It is conceivable that the adjustment mechanism 200 could also be a multi-axis robotic arm.

[0061] In this embodiment, the plate printing production line further includes a baking oven 400 and a storage mechanism 500. The storage mechanism 500 is disposed on the conveyor assembly 100 and is used to store or release workpieces. The adjusting mechanism 200, the printing machine 300, the baking oven 400, and the storage mechanism 500 are arranged sequentially along the conveying direction of the conveyor assembly 100. The conveying direction of the conveyor assembly 100 is a back-to-back direction. The conveyor assembly 100 includes a first conveying section 110, a second conveying section 120, and a third conveying section 120. Section 130, the rear end of the first conveying section 110 is the inlet end, the front end of the first conveying section 110 is connected to the rear end of the second conveying section 120, the adjusting mechanism 200 and the printing machine 300 are opposite to the second conveying section 120, the baking oven 400 is provided with a baking channel, the front end of the second conveying section 120 is connected to the rear end of the baking channel, the front end of the baking channel is connected to the rear end of the third conveying section 130, the storage mechanism 500 is set in the third conveying section 130, the front end of the third conveying section 130 is the outlet end.

[0062] After the printing machine 300 prints the workpiece, the conveyor assembly 100 sends the workpiece into the baking oven 400 for baking. Then, the conveyor assembly 100 conveys the baked workpiece to the storage mechanism 500. The storage mechanism 500 stores and collects the workpiece and releases the stored workpiece when it is needed in the next process. The above-described plate printing production line is easy to combine and use, and meets the needs of automated production.

[0063] In this embodiment, the plate printing production line also includes a lateral shifting mechanism 600. Both the first conveying section 110 and the second conveying section 120 are equipped with lateral shifting mechanisms 600, which are used to move the workpiece along the width direction of the conveyor assembly 100. By providing the lateral shifting mechanism 600, when the workpiece size is small, two or more workpieces can be placed side-by-side in the conveyor assembly 100, improving the space utilization of the conveyor assembly 100. Specifically, the lateral shifting mechanism 600 of the first conveying section 110 arranges the workpieces placed side-by-side in the conveyor assembly 100 into a row, facilitating the rotation of the workpieces by the adjusting mechanism 200. After the workpiece is printed by the printing press 300, the lateral shifting mechanism 600 of the second conveying section 120 moves the workpieces laterally, arranging them into two or more rows, fully utilizing the width of the conveyor assembly 100 to send the workpieces into the baking oven 400 for baking, thus accelerating the baking efficiency.

[0064] In this embodiment, the second conveying section 120 includes an intermediate frame 121 and a plurality of intermediate conveying rollers 122 arranged at intervals along the front-back direction. The intermediate conveying rollers 122 are arranged along the left-right direction and pivotally connected to the intermediate frame 121. The lateral shifting mechanism 600 includes a lateral shifting base 610, a lateral shifting frame 620, six lateral shifting conveyor belts 630, a lateral shifting drive motor 640, and a lateral shifting lifting driver 650. The lateral shifting frame 620 is movably arranged vertically on the lateral shifting base 610. The lateral shifting conveyor belts 630 are arranged along the left-right direction on the lateral shifting frame 620. Two adjacent lateral shifting conveyor belts 630 are arranged along the front-back direction. The vertical projection of the lateral shifting conveyor belts 630 is located between two adjacent intermediate conveying rollers 122. The lateral shifting drive motor 640 is arranged on the lateral shifting frame 620 and is used to drive the lateral shifting conveyor belts 630 to move. The lateral shifting lifting driver 650 is arranged on the lateral shifting base 610 and is used to drive the lateral shifting frame 620 to move vertically. The lateral shifting base 610 is mounted on the intermediate frame 121. A lateral shifting mechanism 600 is provided in the second conveying section 120 to place two or more workpieces side by side along the width of the second conveying section 120. This fully utilizes the size of the baking channel to bake the workpieces and improves baking efficiency. When the height of the lateral shifting conveyor belt 630 is lower than the intermediate conveyor roller 122, the workpiece can be moved into the baking oven 400 by the second conveying section 120 in the front-back direction. When the lateral shifting lifting driver 650 drives the lateral shifting frame 620 to move upward, it moves upward between two adjacent intermediate conveyor rollers 122 until the lateral shifting conveyor belt 630 is higher than the intermediate conveyor roller 122. At this point, the workpiece is lifted by the lateral shifting conveyor belt 630, and the lateral shifting drive motor 640 drives the workpiece to move left and right. Then, the lateral shifting lifting driver 650 drives the lateral shifting frame 620 to move downward, so that the workpiece is repositioned on the intermediate conveyor roller 122, realizing the arrangement of workpieces along the width direction and being sent into the baking oven 400 by the intermediate conveyor roller 122.

[0065] Specifically, the side-shifting conveyor belt 630 is a narrow belt-type conveyor belt, the side-shifting lifting driver 650 is a cylinder, and the side-shifting frame 620 is vertically movable relative to the side-shifting base 610 through guide posts and guide sleeves. The output shaft of the side-shifting drive motor 640 drives the side-shifting conveyor belt 630 to move via belt drive. It is conceivable that the side-shifting frame 620 can also be vertically movable relative to the side-shifting base 610 through a slide rail slider mechanism. The side-shifting conveyor belt 630 can be an array of rollers, the side-shifting lifting driver 650 can be a linear motor, and the side-shifting drive motor 640 drives the side-shifting conveyor belt 630 to move via gear drive.

[0066] Specifically, the number of intermediate conveyor rollers 122 should be three or more, and the number of lateral conveyor belts 630 should be two or more, with the number of intermediate conveyor rollers 122 exceeding the number of lateral conveyor belts 630. The intermediate conveyor rollers 122 have pivot shafts and are pivotally connected to the intermediate frame 121 via these pivot shafts. Alternatively, the pivot shafts can be provided on the intermediate frame 121, and the intermediate conveyor rollers 122 can be mounted on these pivot shafts.

[0067] It is conceivable that the lateral movement mechanism 600 could also be a multi-axis robotic arm with a suction cup, which would grasp the workpiece and move it in the width direction.

[0068] In this embodiment, the third conveying section 130 of the conveyor assembly 100 is located in front of the printing press 300. The third conveying section 130 includes a connecting frame 131 and a plurality of connecting conveying rollers 132 arranged at intervals along the front-back direction. The connecting conveying rollers 132 are arranged in the left-right direction and pivotally connected to the connecting frame 131. The storage mechanism 500 includes a storage frame 510, five storage lifting assemblies, and a storage lifting driver 540. The storage frame 510 is connected to the connecting frame 131. The storage lifting assembly includes two strips 520 arranged at intervals from left to right. The storage and lifting assembly 520 extends vertically and is movably mounted on the storage frame 510. Two storage and lifting assemblies are arranged one in front of the other. A connecting strip 530 is provided between the two strips 520 in each storage and lifting assembly in the left-right direction. Multiple connecting strips 530 are arranged vertically at intervals. The connecting strips 530 in adjacent storage and lifting assemblies are opposite each other in the front-back direction. The vertical projection of the connecting strip 530 is located between two adjacent connecting conveyor rollers 132. The storage and lifting driver 540 is mounted on the storage frame 510 and is used to drive the strips 520 to move vertically. The storage mechanism 500 with the above structure facilitates the temporary storage of workpieces between processes and has good performance. It is conceivable that the storage mechanism 500 can also be set in other positions of the conveyor assembly 100.

[0069] When workpieces need to be stored, the workpiece is moved above the connecting bar 530 by the connecting conveyor roller 132. The storage lifting driver 540 is activated and drives the connecting bar 530 to rise vertically via the bar member 520. The connecting bar 530 moves upward between the two connecting conveyor rollers 132, and two or more connecting bars 530 simultaneously lift the workpiece, thereby storing it. The connecting bar 530 continues to move upward, and at this time, the workpiece can continue to be moved above other connecting bars 530 by the connecting conveyor roller 132. This cycle is repeated, and multiple workpieces can be stored vertically.

[0070] Similarly, when it is necessary to release the stored workpiece, the storage lifting drive 540 drives the connecting bar 530 to descend vertically through the bar 520 until the connecting bar 530 is lower than the connecting conveyor roller 132. At this time, the workpiece is placed on the connecting conveyor roller 132, and the connecting conveyor roller 132 can move the workpiece forward. The cycle continues, so that the workpiece can be continuously released from the storage mechanism 500.

[0071] Specifically, the number of connecting conveyor rollers 132 is three or more, the number of storage and lifting components is two or more, and the number of connecting conveyor rollers 132 is greater than the number of storage and lifting components.

[0072] Specifically, the strip 520 is a chain, and the storage frame 510 has two sprockets arranged vertically for each chain, with each end of the chain wound around one of the two sprockets. When no workpiece is stored, all connecting strips 530 are lower than the connecting conveyor roller 132. The storage lifting drive 540 is a motor, which drives the chain to rotate via belt drive. Specifically, the connecting strip 530 is a round bar. It is conceivable that the connecting strip 530 could also be a square bar, etc., the storage lifting drive 540 could also be an internal combustion engine, and the strip 520 could also be a steel rope, etc. It is conceivable that when the strip 520 is a vertical straight rod, the storage lifting drive 540 could be a motor, with the motor output shaft connected to a gear, and a rack installed on the strip 520, with the gear and rack meshing. It is conceivable that the storage mechanism 500 could also be a multi-axis robot working in conjunction with a storage bin.

[0073] In this embodiment, the first conveying section 110 includes a first conveyor 111 and a second conveyor 112 arranged in a front-to-back direction. The front end of the first conveyor 111 is connected to the rear end of the second conveyor 112. The left-to-right width of the first conveyor 111 is greater than that of the second conveyor 112. The first conveyor 111 is provided with a blocking mechanism 700 and a side-shifting mechanism 600. The blocking mechanism 700 is located at the front end of the first conveyor 111 and is used to stop the left or right side of the first conveyor 111. The rear end of the second conveyor 112 is opposite to the front end of the first conveyor 111 that is not stopped by the blocking mechanism 700. The first conveyor 111 and the second conveyor 112 with the above structure facilitate the output of multiple workpieces arranged along the width on the first conveyor 111 to the second conveyor 112 in a front-to-back row manner through the cooperation of the side-shifting mechanism 600 and the blocking structure, and facilitates the adjustment mechanism 200 to adjust the position of the workpieces.

[0074] Specifically, the first conveyor 111 also includes a first frame, a first conveyor roller pivotally connected to the first frame, and a first drive motor that drives the first conveyor roller via belt drive. The lateral shifting mechanism 600 has the same structure as described above and will not be repeated here. The material blocking mechanism 700 includes a material blocking seat 710, a rotating shaft 720, a baffle 730, a material blocking cylinder 740, and a connecting rod 750. The baffle 730 is mounted on the rotating shaft 720, and the length of the baffle 730 is approximately half the length of the first conveyor roller. The rotating shaft 720 is fixedly connected to one end of the connecting rod 750, and the piston rod of the material blocking cylinder 740 is pivotally connected to the other end of the connecting rod 750. The rotating shaft 720 is pivotally connected to the material blocking seat 710, and the material blocking cylinder 740 is pivotally connected to the material blocking seat 710. When the material blocking cylinder 740 is activated, it drives the rotating shaft 720 to rotate via the connecting rod 750, so that the baffle 730 can be opened or closed to meet different usage needs.

[0075] It is conceivable that the material blocking mechanism 700 can also be a baffle 730, a rotating shaft 720, and a motor, with the motor driving the rotating shaft 720 to rotate.

[0076] Specifically, the second conveyor 112 is a belt conveyor.

[0077] It should be understood that the conveying direction of the conveyor assembly 100 is front-to-back for a single printing group. When multiple printing groups are connected end-to-end, the conveying direction of the conveyor assembly 100 is not limited to the front-to-back direction.

[0078] In this embodiment, the plate printing production line includes two printing groups. Each printing group includes a conveyor assembly 100, an adjusting mechanism 200, a printing machine 300, a baking oven 400, and a storage mechanism 500. The two ends of the conveyor assembly 100 along the conveying direction are the inlet and the outlet, respectively. In two adjacent conveyor assemblies 100, the outlet of one conveyor assembly 100 is connected to the inlet of the other conveyor assembly 100. Specifically, the number of printing groups can be two or more, and those skilled in the art can assemble a suitable number according to actual needs. Setting up two or more printing groups connected end to end allows for automated and continuous multi-printing of workpieces. In this case, part of the first conveyor 111 and the third conveyor section 130 are connected together to form a single device.

[0079] In this embodiment, the printing units are arranged in two rows, with a turning conveyor mechanism 800 positioned between them. The two ends of the turning conveyor mechanism 800 are respectively connected to the conveyor line assemblies 100 of the two printing units. The turning conveyor mechanism 800 includes a fixed section 810, a folding section 820, and a folding driver 830. The folding section 820 is pivotally connected to the fixed section 810. The folding driver 830 is located on the fixed section 810 and is used to drive the folding section 820 to fold or unfold. When the folding section 820 is folded relative to the fixed section 810, the fixed section 810 and the printing units enclose a walking clearance channel. This walking clearance channel facilitates the entry of production personnel into the space between the two printing units in the left-right direction. Specifically, both the fixed section 810 and the folding section 820 of the steering conveyor mechanism 800 are equipped with transfer conveyor rollers. The folding driver 830 is configured as a cylinder, pivotally connected below the fixed section 810. The piston rod of the cylinder is pivotally connected to the folding section 820. When the cylinder is activated, it drives the folding section 820 to unfold, allowing the steering conveyor mechanism 800 to connect the left and right printing groups. When the cylinder is deactivated, it drives the folding section 820 to fold, allowing production personnel to walk and clear the passageway. It is conceivable that the steering conveyor mechanism 800 could also have other structures; for example, the fixed section 810 and the folding section 820 could be pivotally connected, with the unfolding or closing of the folding section 820 controlled by a motor. It is conceivable that three or more printing groups could be arranged in the left-right direction and connected via the steering conveyor mechanism 800. Of course, the folding section 820 could also be manually folded.

[0080] Specifically, a portion of the second conveyor section 120 is a belt conveyor that passes through the regulating mechanism 200 and the printing press 300.

[0081] Specifically, the conveyor assembly 100 is equipped with a photoelectric sensor to detect the position of the workpiece.

[0082] Specifically, the conveyor rollers of the conveyor line assembly 100 are all driven by a motor and belt drive.

[0083] This invention is applicable to the field of plate printing, particularly to the field of glass screen printing. Of course, plate printing in other fields can also utilize the plate printing production line of this invention.
