[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0039] Reference Figures 1 to 8 The steering device proposed in the embodiment of the first aspect of the present invention includes a frame 100, a conveying mechanism, a steering mechanism 300, a lifting mechanism 400 and a pressing mechanism 500; the conveying mechanism is arranged in the frame 100, and the conveying mechanism includes a third driving member 210 and a plurality of roller groups 220, each roller group 220 has a plurality of rollers 221, and the plurality of rollers 221 are coaxially arranged, and the plurality of roller groups 220 are arranged at intervals along the conveying path of the printing plate, and the plurality of roller groups 220 form a conveying surface 230, and the printing plate can be placed on the conveying surface 230, and the third driving member 210 is connected to the roller shafts 222 of the plurality of roller groups 220, thereby driving the roller shafts 222 to rotate, and then driving the rollers 221 to rotate, and when the plurality of roller groups 220 arranged at intervals rotate, the printing plate can be conveyed to the corresponding processing equipment.

[0040] The third driving member 210 is a motor, which may be a servo motor, a speed regulating motor, etc. In this embodiment, the third driving member 210 is connected to the roller shafts 222 of the plurality of roller groups 220 by belt transmission. The rollers 221 may be made of a material with good flexibility, such as plastic, so that the rollers 221 with good flexibility can avoid scratching the printing plate when conveying the printing plate.

[0041] The steering mechanism 300 is arranged on the frame 100 and is located below the conveying path of the printing plate. The steering mechanism 300 can move in the up and down direction; the lifting mechanism 400 is arranged on the frame 100, and the lifting mechanism 400 is connected to the steering mechanism 300. The lifting mechanism 400 can enable the steering mechanism 300 to move in the up and down direction. When the steering mechanism 300 moves upward, one end of the steering mechanism 300 can extend to the top of the conveying surface 230. When the lifting mechanism 400 extends one end of the steering mechanism 300 to the top of the conveying surface 230, the steering mechanism 300 lifts the printing plate from the conveying surface 230 of the conveying mechanism, so that the printing plate is lifted above the roller group 220, and the printing plate is separated from the conveying mechanism.

[0042] The pressing mechanism 500 is arranged on the frame 100. The pressing mechanism 500 is arranged corresponding to the steering mechanism 300 and is located above the conveying mechanism. When the steering mechanism 300 lifts the printing plate from the conveying surface 230 of the conveying mechanism, the pressing mechanism 500 presses the printing plate from above, thereby cooperating with the steering mechanism 300 up and down to press the printing plate. After pressing the printing plate, the steering mechanism 300 rotates to rotate the printing plate to a predetermined angle to realize the steering of the printing plate. Therefore, the steering device of the present invention presses the printing plate in the up and down direction through the pressing mechanism 500 and the steering mechanism 300, so that the printing plate is stable and will not fall during the steering process, and has a simple structure and stable operation.

[0043] It can be understood that, in some embodiments, the third driving member 210 can be connected to the roller shafts 222 of the plurality of roller groups 220 through gear transmission, which is not limited herein.

[0044] It should be noted that the conveying surface 230 is a virtual plane, and the conveying surface 230 is introduced to facilitate the description of the relative positions of the steering mechanism 300 and the subsequent centering mechanism 600 and the conveying mechanism. Figure 4 The conveying surface 230 refers to a plane formed by the top edges of the plurality of rollers 221 in the plurality of roller groups 220. When the conveying mechanism is in operation, the printing plate can move on the conveying surface 230 along the conveying direction.

[0045] Reference Figure 1 , Figure 2 , Figure 5In some embodiments, the conveying mechanism further includes a baffle 240 and a control switch 250. Along the conveying path of the printing plate, the baffle 240 is located behind the steering mechanism 300 and is arranged on the frame 100 in a manner that it can be raised or lowered. The control switch 250 is located on the conveying path, and the control switch 250 can control the baffle 240 to be raised or lowered. When the conveying mechanism conveys the printing plate and one end of the printing plate approaches the baffle 240, the control switch 250 is triggered. The control switch 250 controls the driving member of the baffle 240, such as a cylinder, to move, so that the baffle 240 extends out to block the printing plate, so that the printing plate is located above the steering mechanism 300. The control switch 250 can be a photoelectric control switch 250, which is not limited here.

[0046] Reference Figure 7 In some embodiments, the steering mechanism 300 includes an assembly plate 310, a first driving member 320 and a supporting member 330. The first driving member 320 is arranged on the assembly plate 310, and a steering gear 350 is arranged on the assembly plate 310. The first driving member 320 adopts a motor, and the first driving member 320 is connected to the steering gear 350 in a transmission manner. The steering gear 350 is provided with an output shaft 351, and the supporting member 330 is provided with a rotating shaft 340. The output shaft 351 and the rotating shaft 340 are connected by a coupling 360. The first driving member 320 drives the steering gear 350 to rotate, and the steering gear 350 drives the output shaft 351 to rotate, thereby driving the supporting member 330 to rotate in a horizontal plane. The assembly plate 310, the first driving member 320 and the steering gear 350 are located below the conveying mechanism, and the supporting member 330 is located above the axis of the corresponding roller 221. The rotating shaft 340 passes through the gap between two roller groups 220 and is connected to the supporting member 330. Figure 7 As shown, in this embodiment, the supporting member 330 is in a plate shape, and the supporting member 330 is provided with at least one avoidance hole 331 , and the avoidance hole 331 is used to avoid the corresponding roller 221 .

[0047] Reference Figure 2 , Figure 7 The lifting mechanism 400 is a cylinder, the output end of the cylinder is connected to the assembly plate 310, and the cylinder is used to drive the assembly plate 310 to move in the up and down directions.

[0048] Specifically, a mounting plate 370 is provided on the frame 100, a linear bearing 380 is installed on the mounting plate 370, the assembly plate 310 is connected to the mounting plate 370 through the linear bearing 380, and the cylinder is installed on the mounting plate 370. When the cylinder is actuated, it can drive the assembly plate 310 to move in the up and down directions, so that the supporting member 330 has a first state and a second state. When the lifting mechanism 400 puts the supporting member 330 in the first state, the supporting member 330 is located above the conveying surface 230, and the supporting member 330 can support the printing plate so that the printing plate is higher than the roller group 220 of the conveying mechanism, so as to facilitate the subsequent steering of the printing plate by the steering mechanism 300, thereby avoiding the interference of the conveying mechanism with the steering of the printing plate; when the lifting mechanism 400 puts the supporting member 330 in the second state, the supporting member 330 is located below the conveying surface 230, and the upper part of the roller 221 below the supporting member 330 is inserted into the corresponding avoidance hole 331, so that the top end edge of the roller 221 protrudes from the surface of the supporting member 330, so that the conveying mechanism can normally convey the printing plate, thereby avoiding the interference of the supporting member 330 with the printing plate during the conveying process.

[0049] It can be understood that in some embodiments, the supporting member 330 can be a bracket, the middle part of the bracket is connected to the first driving member 320 through the connecting shaft 540, and the branch structure constituting the bracket is arranged between adjacent rollers 221. When the lifting mechanism 400 drives the assembly plate 310 to move in the up and down directions, the bracket moves up and down synchronously, thereby achieving the purpose of supporting the printing plate and avoiding interference with the transportation of the printing plate.

[0050] It should be noted that the first driving member 320 can be connected to the steering gear 350 through belt transmission, gear transmission, shaft transmission, etc., which is not limited here.

[0051] Reference Figure 7 A plurality of rubber pads 332 are provided on the supporting member 330 , and the plurality of rubber pads 332 are arranged at intervals on the surface of the supporting member 330 . The rubber pads 332 are used to abut against the printing plate to avoid scratching the printing plate during the lifting and turning process.

[0052] Reference Figure 2 , Figure 6 , Figure 8, in some embodiments, the material pressing mechanism 500 is located above the conveying mechanism. The material pressing mechanism 500 includes a first cylinder 510 and a pressing plate 520. The first cylinder 510 is arranged on the frame 100, and the pressing plate 520 is arranged at the output end of the first cylinder 510 and can rotate around the axis of the output end of the first cylinder 510. One end of the steering mechanism 300 that can extend above the conveying mechanism is opposite to the pressing plate 520. When the lifting mechanism 400 lifts the steering mechanism 300 upward, the pressing plate 520 of the material pressing mechanism 500 moves downward under the action of the first cylinder 510, and the pressing plate 520 and the supporting member 330 cooperate with each other to tightly press the printing plate. And the pressing plate 520 can rotate along the axis of the output end of the first cylinder 510. Thus, when the printing plate turns, the pressing plate 520 and the supporting member 330 can rotate in the same direction as the printing plate while keeping the pressing state of the printing plate to prevent the pressing plate 520 from scratching the printing plate.

[0053] Refer to Figure 6 , in some embodiments, there are two first cylinders 510. Both of the two first cylinders 510 are installed on the frame 100. The output shafts of the two first cylinders 510 are fixedly connected to the connecting member 530. Both ends of the connecting member 530 are connected to the frame 100 through linear bearings 380. A connecting shaft 540 is provided on the connecting member 530. The pressing plate 520 is rotatably arranged at one end of the connecting shaft 540 away from the connecting member 530. Thus, the two first cylinders 510 drive the connecting member 530 to move in the up and down direction, and further drive the pressing plate 520 to move in the up and down direction, making the movement of the pressing plate 520 in the up and down direction stable.

[0054] Refer to Figure 6 , in some embodiments, the pressing plate 520 is provided with a plurality of pressing rods 521. The plurality of pressing rods 521 are arranged along the circumferential direction of the pressing plate 520. The pressing rods 521 extend along the axial direction of the connecting shaft 540. A rubber sleeve 522 is provided at one end of the pressing rod 521 away from the pressing plate 520. The rubber sleeve 522 is used to abut against the printing plate to prevent the printing plate from being scratched when the material pressing mechanism 500 presses the printing plate.

[0055] Refer to Figure 2 , Figure 6 , in some embodiments, the steering device further includes a centering mechanism 600. The centering mechanism 600 is used to move the printing plate to the middle position of the conveying mechanism to prevent the printing plate from deviating from its position on the conveying mechanism during the conveying process and after turning.

[0056] Refer to Figure 6, in some embodiments, the centering mechanism 600 includes a second driving member 610, a slide rail 620, a driven wheel 630, and two moving members 640. The slide rail 620 is disposed on the frame 100. The second driving member 610 is a motor, which can be a servo motor, a speed regulating motor, etc. The second driving member 610 is disposed at one end of the slide rail 620; the driven wheel 630 is disposed on the frame 100 and is located at the end of the slide rail 620 far from the second driving member 610. The driving wheel of the second driving member 610 is connected to the driven wheel 630 by a belt; the two moving members 640 are slidably disposed on the slide rail 620, and one of the moving members 640 is fixedly connected to the belt on one side of the driven wheel 630, and the other moving member 640 is fixedly connected to the belt on the other side of the driven wheel 630. Each moving member 640 is provided with a plurality of dial rods 650, and the dial rods 650 on the two moving members 640 are oppositely disposed.

[0057] When the printing plate needs to be centered, the second driving member 610 rotates clockwise, driving the two moving members 640 to move towards each other. The dial rods 650 on the two moving members 640 push the printing plate, causing the printing plate to move towards the middle of the conveying mechanism, so that the printing plate is in the middle position of the conveying mechanism, preventing the printing plate from running off during the conveying process.

[0058] Refer to Figure 6 , in this embodiment, the moving member includes a fixed block 641, a connecting block 642, two connecting rods 643, and a mounting block 644. The fixed block 641 is fixedly connected to the belt. The connecting block 642 is connected to the fixed block 641 and extends to both sides of the fixed block 641. The two connecting rods 643 are disposed at both ends of the connecting block 642. The mounting block 644 is connected to the ends of the two connecting rods 643 far from the connecting block 642. The dial rod 650 is disposed on the mounting block 644. The moving member with this structure is not only simple in structure but also convenient for the installation of the dial rod 650.

[0059] Refer to Figure 1 、 Figure 4 、 Figure 5 , in some embodiments, the centering mechanism 600 further includes a pulley assembly 700. The pulley assembly 700 includes a second cylinder 610, a connecting plate 720, and a plurality of pulley groups 730. The plurality of pulley groups 730 are connected to the connecting plate 720. Each pulley group 730 includes a support member 731 and a plurality of pulleys 732. The support member 731 is disposed along the width direction of the conveying mechanism. The plurality of pulleys 732 are spaced apart along the width direction of the conveying mechanism. And, along the conveying path of the printing plate, the pulley group 730 is disposed between the corresponding two roller groups 220. The connecting plate 720 is slidably disposed on the frame 100. The output end of the second cylinder 610 is connected to the connecting plate 720. The second cylinder 610 can drive the connecting plate 720 to move up and down on the frame 100, thereby driving the pulley group 730 to move up and down.

[0060] The pulley assembly 700 has a first state and a second state. When the second cylinder 610 drives the connecting plate 720 to move upward, the pulley assembly 700 is in the first state. At this time, the pulley 732 at least partially protrudes from the conveying surface 230, and the pulley 732 of the pulley assembly 700 supports the printing plate. The second driving member 610 drives the lever 650 to toggle the printing plate, and the printing plate drives the pulley 732 of the pulley assembly 700 to roll, so that the contact between the pulley 732 and the printing plate is a rolling contact, reducing the friction force of the printing plate during the centering process and avoiding scratching the printing plate.

[0061] When the second cylinder 610 drives the connecting plate 720 to move downward, the pulley assembly 700 is in the second state. At this time, the pulleys 732 of the pulley set 730 are all located below the conveying surface 230 to prevent the pulley assembly 700 from interfering with the conveyance of the printing plate when the conveying mechanism conveys the printing plate.

[0062] Refer to Figure 4 , the pulley assembly 700 is provided with an avoidance space 740 for avoiding the supporting member 330 to prevent the supporting member 330 from interfering with the pulley assembly 700 when it supports the printing plate.

[0063] The pulley 732 can be made of a material with good flexibility such as plastic. Therefore, the pulley 732 with good flexibility can avoid scratching the printing plate when the printing plate is centered.

[0064] Refer to Figures 2 to 8, the steering device of the present invention is used to receive the printing plate conveyed by the screen printing equipment. In a specific embodiment of the present invention, after the printing plate is printed by the screen printing equipment, it is conveyed to the conveying mechanism of the present steering device. When the conveying mechanism conveys the printing plate to be close to the baffle 240 under the drive of the third driving member 210, the control switch 250 is triggered. After triggering the control switch 250, the control switch 250 controls the driving member of the baffle 240, such as a cylinder, to act, so that the baffle 240 extends out to block the printing plate, causing the printing plate to stop above the steering mechanism 300. The pulley assembly 700 in the centering mechanism 600 moves upward under the drive of the second cylinder 610, lifting the printing plate above the roller 221, placing the printing plate on the pulley assembly 700. The lever 650 of the centering mechanism 600 moves the printing plate to be centered on the pulley 732 under the action of the second driving member 610; the lifting mechanism 400 drives the steering mechanism 300 to move upward, so that the supporting member 330 of the steering mechanism 300 is higher than the pulley 732. At this time, the printing plate is supported on the supporting member 330.
