Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat-sensitive printing plate preparation, in particular to an environmentally friendly heat-sensitive printing plate preparation method. BACKGROUND

[0002] A heat-sensitive printing plate is a special printing plate used in heat-sensitive printing technology, which prints by utilizing the characteristics of heat-sensitive materials; in this printing technology, the heat-sensitive printing plate acts as a template, serving as a medium that receives heat energy and transfers patterns to paper or other printing materials during the printing process.

[0003] The heat-sensitive printing plate preparation method generally includes substrate coating, drying treatment, exposure operation, development treatment, fixation treatment, quality inspection, and packaging and storage steps, among which quality inspection is one of the most important steps. The quality inspection of the heat-sensitive printing plate is generally carried out by machine vision CCD camera, which captures the heat-sensitive printing plate through the CCD camera to obtain high-quality image data, and feeds the image data back to the computer for analysis. If the pattern and text on the image are defect-free, the quality inspection is qualified, otherwise it is unqualified.

[0004] At present, the CCD camera visual shooting detection for the quality of the heat-sensitive printing plate detects each heat-sensitive printing plate one by one in the detection process. Therefore, in the detection process, the jitter caused by the operation of the heat-sensitive printing plate conveying belt itself will cause the position of the heat-sensitive printing plate to deviate, resulting in incomplete detection of the heat-sensitive printing plate in the detection process, affecting the detection efficiency of the heat-sensitive printing plate. Moreover, since the heat-sensitive printing plate is detected by being conveyed under the CCD camera, when the CCD camera is placed on the conveying belt and the heat-sensitive printing plate is conveyed under the CCD camera, the heat-sensitive printing plate itself will vibrate to a certain extent, which will affect the normal detection work of the heat-sensitive printing plate.

[0052] The visual quality inspection equipment involved in the above S6 step includes a support frame 1, the upper surface of the support frame 1 is provided with a conveying belt 2, a plurality of limiting mechanisms 8 for positioning the heat-sensitive printing plate are uniformly distributed on the conveying belt 2, the inner side of the conveying belt 2 is provided with a support plate 9 for supporting the conveying belt 2, the front and rear sides of the conveying belt 2 are both fixedly connected with two left and right symmetrical electric sliding seats 7, the four electric sliding seats 7 are jointly and upwardly and downwardly connected with a sliding frame 4, and the upper surface of the sliding frame 4 is provided with a CCD camera detection unit 5.

[0053] The second position adjusting mechanism 6 is used to adjust the position of the heat-sensitive printing plate in the front and rear directions, and the number of the second position adjusting mechanism 6 is two and symmetrically arranged on the conveying belt 2.

[0054] The first position adjusting mechanism 3 is used to adjust the position of the heat-sensitive printing plate in the left and right directions in cooperation with the limiting mechanism 8, and the first position adjusting mechanism 3 is arranged on the right side of the sliding frame 4.

[0055] As shown in Figure 3 The limiting mechanism 8 includes a limiting top rod 82 fixedly connected to the left side of the sliding frame 4, and a limiting piece 81 arranged on the conveying belt 2.

[0056] As shown in Figure 4As shown, the limiting piece 81 comprises a limiting plate 811 fixedly connected to the conveying belt 2, the upper surface of the limiting plate 811 is provided with a limiting hole 813, the right side surface of the limiting plate 811 is provided with a mounting sliding groove 814, the inside of the mounting sliding groove 814 is slidably connected with two limiting blocks 812, the upper end of the limiting hole 813 is provided with a rounded corner, the front and rear ends of the mounting sliding groove 814 are provided with a horn shape, and the limiting blocks 812 and the limiting plate 811 are relatively fixed through fastening bolts.

[0057] In specific use, first, the staff places the heat-sensitive printing plate to be detected on the conveying belt 2 from the right end of the conveying belt 2, and places the heat-sensitive printing plate relative to the position of the limiting plate 811, and the left end of the heat-sensitive printing plate abuts against the right side of the limiting plate 811, so that the approximate position of the heat-sensitive printing plate on the conveying belt 2 is determined, then the conveying belt 2 intermittently conveys the heat-sensitive printing plate from right to left, when the heat-sensitive printing plate moves directly below the CCD camera detection unit 5, at this time, the sliding frame 4 moves downward in the electric sliding seat 7, drives the CCD camera detection unit 5 to move to the detection position, and the front and rear positions of the heat-sensitive printing plate on the conveying belt 2 are adjusted through the second position adjusting mechanism 6 in the process that the sliding frame 4 moves downward, and the left and right positions of the heat-sensitive printing plate on the conveying belt 2 are adjusted through the first position adjusting mechanism 3.

[0058] As shown in Figure 5 , taking the second position adjusting mechanism 6 on the front side as an example, the second position adjusting mechanism 6 comprises a pushing frame 61 fixedly connected to the sliding frame 4, the front surface of the conveying belt 2 is fixedly connected with two left and right symmetrical elastic expansion connecting seats 64, the expansion ends of the two elastic expansion connecting seats 64 are fixedly connected with a second adjusting plate 62, and the front surface of the conveying belt 2 and located between the two elastic expansion connecting seats 64 is provided with a linkage 63.

[0059] As shown in Figure 6 and Figure 7 , the linkage 63 comprises a fixed horizontal plate 632 fixedly connected to the front surface of the conveying belt 2, the front surface of the fixed horizontal plate 632 is fixedly connected with a gear set 634, the front surface of the fixed horizontal plate 632 and located on the left and right sides of the gear set 634 is fixedly connected with a mounting bracket 633, the front surface of the fixed horizontal plate 632 and located at the middle position is fixedly connected with a connecting seat 635, the upper surface of the connecting seat 635 is slidably connected with a first toothed plate 631, and the rear surface of the mounting bracket 633 is slidably connected with a second toothed plate 636.

[0060] As shown in Figure 6 and Figure 7As shown, two second toothed plates 636 mesh with gears at the left and right ends of the gear set 634, respectively. The first toothed plate 631 meshes with the gear in the middle of the gear set 634. The rear end of the first toothed plate 631 is fixedly connected to the front surface of the second adjusting plate 62. A first protrusion is provided at the left end of the second adjusting plate 62. The size of the first protrusion matches the size of the mounting groove 814. The protrusion slides in cooperation with the mounting groove 814. Two symmetrical second protrusions are provided on the front surface of the push frame 61. The positions of the second protrusions correspond one-to-one with the positions of the two mounting brackets 633. The bottom end of the push frame 61 is located directly above the second toothed plate 636. The front surface of the push frame 61 slides in cooperation with the rear surface of the mounting bracket 633.

[0061] In practical use, when the front and rear positions of the thermal printing plate are adjusted by the second position adjustment mechanism 6, the push frame 61 pushes the second toothed plate 636 to move downward on the mounting bracket 633 as the sliding frame 4 moves downward. At this time, the second toothed plate 636 drives the gears on the gear set 634 to rotate synchronously. At the same time, the gears on the linkage 63 drive the first toothed plate 631 to move towards the thermal printing plate on the connecting seat 635. At this time, the first toothed plate 631 pushes the second adjustment plate 62 to move synchronously. At the same time, the second adjustment plate 62 drives the elastic telescopic connecting seat 64 to stretch. As the two second adjustment plates 62 move towards the thermal printing plate synchronously, the front and rear positions of the thermal printing plate are adjusted by the two second adjustment plates 62.

[0062] Meanwhile, when the second adjusting plate 62 moves towards the thermal printing plate, the first protrusion at the right end of the second adjusting plate 62, in conjunction with the flared opening on the mounting slide 814, can smoothly slide into the interior of the mounting slide 814. The mounting slide 814 makes the movement of the second adjusting plate 62 more stable. At the same time, the limiting block 812 inside the mounting slide 814 limits the movement distance of the second adjusting plate 62, preventing damage to the edge of the thermal printing plate when the second adjusting plate 62 is adjusting its position.

[0063] like Figure 8 As shown, the first position adjustment mechanism 3 includes a connector 32 disposed on the right side of the sliding frame 4. The bottom end of the connector 32 is fixedly connected to a mounting box 34. A pusher 33 is disposed on the mounting box 34. A first adjustment plate 31 is fixedly connected to the left side of the pusher 33.

[0064] In specific use, when adjusting the position of the heat-sensitive printing plate in the left-right direction by the first position adjusting mechanism 3, first, the sliding frame 4 pushes the mounting box 34 to move towards the conveying belt 2 by the connecting piece 32, and when the mounting box 34 is attached to the conveying belt 2, the connecting piece 32 pushes the first adjusting plate 31 to move away from the mounting box 34 by the pushing piece 33, while the left-right position of the heat-sensitive printing plate is adjusted by the limiting plate 811.

[0065] As shown in Figure 8 and Figure 9 , the connecting piece 32 comprises a connecting cross strut 322 fixedly connected to the sliding frame 4, the lower surface of the connecting cross strut 322 is fixedly connected with two front-rear symmetrical supporting elastic extension rods 321, the bottom ends of the two supporting elastic extension rods 321 are fixedly connected to the upper surface of the mounting box 34, the right middle position of the connecting cross strut 322 is fixedly connected with a pushing rod 323, and the bottom end of the pushing rod 323 is hingedly connected with two front-rear symmetrical connecting plates 324.

[0066] In specific use, when the sliding frame 4 moves downwards, the sliding frame 4 pushes the connecting cross strut 322 to move downwards synchronously, at this time, the connecting cross strut 322 pushes the mounting box 34 to move towards the conveying belt 2 by the supporting elastic extension rods 321, when the mounting box 34 is attached to the conveying belt 2, the connecting cross strut 322 continues to move downwards with the continuous downward movement of the sliding frame 4, and at the same time, the supporting elastic extension rods 321 are compressed, and the connecting cross strut 322 pushes the two connecting plates 324 to rotate on the pushing rod 323 by the pushing rod 323, so that the included angle between the two connecting plates 324 gradually increases.

[0067] As shown in Figure 8 and Figure 9 , the pushing piece 33 comprises two front-rear symmetrical connecting sliding grooves 333 opened in the right side surface of the mounting box 34, the inside of the connecting sliding groove 333 is slidingly connected with a pushing block 332, the two pushing blocks 332 correspond to the two connecting plates 324 one by one, the bottom end of the connecting plate 324 is hingedly connected to the upper surface of the corresponding pushing block 332, the left end of the pushing block 332 is rotatably connected with a connecting roller 337, the right side surface of the mounting box 34 is fixedly connected with a mounting sliding seat 331, and the pushing block 332 is elastically slidingly connected with the mounting sliding seat 331.

[0068] As shown in the figure, the left side inner wall of the installation box 34 is elastically and slidably connected with two front and back symmetrical connecting elastic telescopic rods 334, the left ends of the two connecting elastic telescopic rods 334 penetrate to the outside of the installation box 34 and are fixedly connected with the first adjusting plate 31, the right side surface of the first adjusting plate 31 and located at the front and back sides of the two connecting elastic telescopic rods 334 are respectively fixedly connected with fixed columns 335, the right ends of the fixed columns 335 penetrate to the inside of the installation box 34 and are fixedly connected with pushing cam blocks 336.

[0069] In specific use, when the included angle between the two connecting plates 324 gradually increases, at this time, the two connecting plates 324 gradually move away from each other away from the one end of the pushing rod 323, at this time, the connecting plate 324 pushes the pushing block 332 to synchronously slide in the connecting sliding groove 333, when the pushing block 332 slides in the connecting sliding groove 333, the connecting roller 337 at the left end of the pushing block 332 slides on the cam surface of the pushing cam block 336, a pushing force is generated on the pushing cam block 336, the pushing cam block 336 moves to the left, at this time, the pushing cam block 336 pushes the first adjusting plate 31 to move to the direction close to the heat-sensitive printing plate through the fixed column 335, the left and right directions of the heat-sensitive printing plate are limited by the limiting plate 811, at the same time, the first adjusting plate 31 stretches the connecting elastic telescopic rod 334, and the first adjusting plate 31 will eventually abut against the right end of the second adjusting plate 62 in the process of sliding to the left, which can avoid the first adjusting plate 31 from sliding too much and causing damage to the edge of the heat-sensitive printing plate, at the same time, the sliding frame 4 moves downward, drives the limiting jacks 82 to close to the limiting plate 811, at the same time, the rounded corners on the limiting hole 813 can smoothly insert the bottom end of the limiting jack 82 into the inside of the limiting hole 813, so that the conveying belt 2 remains stable.

[0070] At this time, the front and back and left and right positions of the heat-sensitive printing plate are adjusted, visual quality detection of the heat-sensitive printing plate is started by the CCD camera detection unit 5, when the detection is completed, the sliding frame 4 is restored to the original position on the electric sliding seat 7, at the same time, the first adjusting plate 31 and the second adjusting plate 62 are synchronously restored to the original position under the action of the elastic force of the connecting elastic telescopic rod 334 and the elastic force of the elastic telescopic connecting seat 64, according to the detection result of the CCD camera detection unit 5, the staff selects the detected heat-sensitive printing plate on the conveying belt 2, then the next heat-sensitive printing plate to be detected is conveyed to the detection position through the conveying belt 2, and the above steps are repeated to continuously detect the visual quality of the heat-sensitive printing plate in batches.

[0071] Working principle: in specific use, first, the worker places the heat-sensitive printing plate to be detected on the conveying belt 2 from the right end of the conveying belt 2, and puts the heat-sensitive printing plate relative to the position of the limiting plate 811, and the left end of the heat-sensitive printing plate is abutted against the right side of the limiting plate 811, so as to determine the approximate position of the heat-sensitive printing plate on the conveying belt 2, and then the conveying belt 2 intermittently conveys the heat-sensitive printing plate from right to left, when the heat-sensitive printing plate moves to the position directly below the CCD camera detection unit 5, at this time, the sliding frame 4 moves downward in the electric sliding seat 7, drives the CCD camera detection unit 5 to move to the detection position, and then the sliding frame 4 moves to the direction close to the heat-sensitive printing plate through the push frame 61 cooperating with the linkage 63 to push the second adjusting plate 62, so as to adjust the position of the heat-sensitive printing plate in the front direction.

[0072] At the same time, the sliding frame 4 pushes the mounting box 34 to move to the conveying belt 2 through the connecting piece 32, when the mounting box 34 is attached to the conveying belt 2, at this time, with the continuous downward movement of the connecting piece 32, the connecting piece 32 pushes the first adjusting plate 31 to move away from the mounting box 34 through the pushing piece 33, and at the same time, the limiting plate 811 adjusts the position of the heat-sensitive printing plate in the left-right direction, when the position adjustment of the heat-sensitive printing plate is completed, at this time, the heat-sensitive printing plate is kept stable, and the visual quality detection of the heat-sensitive printing plate is started through the CCD camera detection unit 5, when the detection is completed, the sliding frame 4 is restored to the original position on the electric sliding seat 7, and at the same time, the first adjusting plate 31 and the second adjusting plate 62 are synchronously restored to the original position, according to the detection result of the CCD camera detection unit 5, the worker selects the heat-sensitive printing plate on the conveying belt 2 after detection, and then the next heat-sensitive printing plate to be detected is conveyed to the detection position through the conveying belt 2, and the above steps are repeated to continuously detect the visual quality of the heat-sensitive printing plate in batches.
