Description

Technical Field

[0001] This invention belongs to the field of resin cutting technology, and specifically relates to a cutting machine for photosensitive resin plate making. Background Technology

[0002] Photosensitive resins are a class of functional polymer materials that can undergo polymerization or degradation reactions under light conditions. These materials need to meet core performance requirements such as high sensitivity, resolution, film-forming ability, and chemical stability, and are widely used in printing plate making, integrated circuit manufacturing, laser holography, microelectronics processing and other fields.

[0003] During the cutting and processing of photosensitive resin, since it is a soft sheet, it is necessary to press and position it during the cutting process to prevent the photosensitive resin sheet from shifting during the cutting process. Therefore, we propose a cutting machine for photosensitive resin plate making that can press the photosensitive resin sheet on both sides of the cutter. Summary of the Invention

The cutting platform is also equipped with two sets of clamping mechanisms, which are respectively located on both sides of the cutter.

Detailed Implementation

[0014] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] like Figures 1 to 8 The illustrated photosensitive resin plate-making cutting machine includes a cutting platform 100, with electric drive belts 101 on both sides of the cutting platform 100. The photosensitive resin sheet can be driven by the electric drive belts 101 on both sides. It should be noted that the electric drive belts 101 on both sides have the same transmission direction, so that the photosensitive resin sheet can be conveyed from one side of the cutting platform 100 to the other side. At the same time, according to the required cutting length, the conveying length of the electric drive belts 101 can be controlled by a PLC programming program. This is a conventional technology for quantitative control of the feeding length, which will not be described in detail here. The cutting platform 100 is equipped with a cutting mechanism, which is located between the electric drive belts 101 on both sides. The cutting mechanism includes: Gantry 110 extends longitudinally and is fixedly installed to the cutting platform 100; Slide 111 is longitudinally slidably connected to the upper side of gantry frame 110; Electric telescopic rod 112, which is installed and fixed on slide 111 with the telescopic end facing down; The cutter 113 is fixedly connected to the telescopic end of the electric telescopic rod 112; The gantry 110 is also equipped with a longitudinal drive assembly, which is used to drive the slide 111 to slide longitudinally. The cutting platform 100 is also equipped with two sets of clamping mechanisms, which are respectively located on both sides of the cutter 113.

[0016] The workflow of the cutting mechanism, longitudinal drive assembly, and clamping mechanism during the cutting of photosensitive resin sheets is as follows: ① The longitudinal drive assembly drives the slide 111 to one longitudinal end of the gantry 110, and at the same time, the telescopic end of the electric telescopic rod 112 of the slide 111 is at its highest position, moving the cutter 113 to the high position, and the two sets of clamping mechanisms are also at the high position. ② One side of the electric drive belt 101 conveys the photosensitive resin sheet at a fixed length, so that one side of the photosensitive resin sheet is on the other side of the electric drive belt 101, and the electric drive belt 101 on that side is not started at this time. ③ The electric telescopic rod 112 lowers the cutter 113 to its lowest position. At the same time, two sets of clamping mechanisms clamp the photosensitive resin sheet from both sides of the cutter 113. Then, the longitudinal drive assembly drives the slide 111 to move longitudinally, so that the cutter 113 cuts the photosensitive resin sheet. Through the clamping action of the two sets of clamping mechanisms, the photosensitive resin sheet can be effectively positioned, thereby preventing the photosensitive resin sheet from shifting during the cutting process. ④ After cutting, the electric telescopic rod 112 raises the cutter 113 back to the highest position. At the same time, the two sets of clamping mechanisms no longer clamp the photosensitive resin sheet, and the electric transmission belt 101 on the other side starts to send out the cut sheet. ⑤ Repeat steps ① through ④ above to complete the cutting of the entire photosensitive resin sheet.

[0017] It should be noted that a horizontally straight reference line (not shown in the figure) can be drawn on the surface of the electric drive belt 101 so that the photosensitive resin sheet can be aligned with the reference line and kept flat.

[0018] This invention, by setting up two sets of clamping mechanisms, effectively avoids the problem of photosensitive resin sheet shifting during the cutting process by clamping the photosensitive resin sheet from both sides of the cutter.

[0019] As a structural description of the longitudinal drive component in the technical solution of this embodiment, such as Figures 1 to 3 As shown, the longitudinal drive component includes: Motor 114 is installed and fixed to gantry frame 110; The longitudinal drive screw 115 is fixedly connected to the output end of the motor 114; The longitudinal drive screw 115 passes through the slide 111 and is threadedly connected to the slide 111.

[0020] When the longitudinal drive assembly is driven, the motor 114 starts and drives the longitudinal transmission screw 115 to rotate. Through the threaded transmission between the longitudinal transmission screw 115 and the slide 111, the slide 111 extends the longitudinal transmission screw 115 to move longitudinally, thereby driving the cutter 113 to move longitudinally to cut the photosensitive resin sheet. The motor 114 is also controlled by the PLC programming program to adjust the output direction and the number of rotations of the motor 114, thereby controlling the longitudinal stroke and longitudinal direction of the cutter 113.

[0021] Example 2: This is a structural description of the clamping mechanism in Example 1, such as... Figures 1 to 8 As shown, both sets of clamping mechanisms include: The longitudinal connecting frame 120 is vertically slidably mounted on the cutting platform 100; Multiple elastic connectors 121 are fixed to the bottom of the longitudinal connecting frame 120; The lower ends of each elastic connector 121 are connected and fixed to the pressure plate 122; Both sets of clamping mechanisms are equipped with a vertical drive assembly, which is used to drive the two longitudinal connecting frames 120 to move vertically. Among them, such as Figures 1 to 8 As shown, both longitudinal connecting frames 120 are provided with longitudinal sliding grooves 123; The vertical drive assembly includes a horizontal platform 124 fixedly connected to the telescopic end of the electric telescopic rod 112, and both ends of the horizontal platform 124 are provided with positioning sliders 125 that match the longitudinal slide groove 123; When the telescopic end of the electric telescopic rod 112 raises the cutter 113 to the high position, the lower end face of the pressure plate 122 is lower than the lower end of the cutter 113.

[0022] Based on the technical solution of this embodiment, and in conjunction with the workflow of Embodiment 1, the workflow is further explained as follows: ① The longitudinal drive assembly drives the slide 111 to one longitudinal end of the gantry 110, and at the same time the telescopic end of the electric telescopic rod 112 of the slide 111 is at its highest position, moving the cutter 113 to the high position. Through the connection and transmission between the positioning slider 125 of the horizontal platform 124 and the longitudinal slide groove 123 of the longitudinal connecting frame 120, when the telescopic end of the electric telescopic rod 112 is in the highest position, the two longitudinal connecting frames 120 can be raised to the highest position. Figure 4 and Figure 5 As shown, the lower end face of the pressure plate 122, which is fixed by multiple elastic connectors 121, is lower than the lower end of the cutter 113; ② One side of the electric drive belt 101 conveys the photosensitive resin sheet at a fixed length, so that one side of the photosensitive resin sheet is on the other side of the electric drive belt 101, and the electric drive belt 101 on that side is not started at this time. ③ The electric telescopic rod 112 lowers the cutter 113 to its lowest position. Through the connecting transmission of the crossbeam 124, the longitudinal connecting frame 120 descends synchronously. Since the lower end of the pressure plate 122 is lower than the lower end of the cutter 113, the pressure plate 122 will first contact the photosensitive resin sheet. As the cutter 113 continues to descend to its lowest position, the pressure plate 122 stops descending due to contact with the photosensitive resin sheet, thereby compressing the elastic connector 121 and generating elastic force. Under the action of this elastic force, the pressure plate 122 can press the photosensitive resin sheet tightly. At this time, if... Figure 6 and Figure 7 As shown; Then the longitudinal drive assembly drives the slide 111 to move longitudinally. Since the cross platform 124 and the longitudinal connecting frame 120 are longitudinally slidably connected through the positioning slider 125, the cutter 113 can cut the photosensitive resin sheet. Under the pressing action of the two sets of pressing mechanisms, the photosensitive resin sheet can be effectively positioned, thereby preventing the photosensitive resin sheet from shifting during the cutting process. ④ After cutting, the electric telescopic rod 112 raises the cutter 113 back to the highest position. Similarly, at the same time, the two sets of clamping mechanisms will return to their original positions as the electric telescopic rod 112 moves upward and will no longer clamp the photosensitive resin sheet. The electric drive belt 101 on the other side starts and sends out the cut sheet. ⑤ Repeat steps ① through ④ above to complete the cutting of the entire photosensitive resin sheet.

[0023] Through further design of this embodiment, the clamping mechanism can be automatically clamped and released by the extension and retraction of the electric telescopic rod 112 without the need for additional power drive.

[0024] As a further preferred embodiment of the technical solution, such as Figure 8 As shown, a rubber strip (not shown in the figure) is bonded to the bottom of the pressure plate 122. The elastic connector 121 includes a sleeve 1211 and a slide rod 1212 that is slidably connected to the sleeve 1211. Magnet blocks 1213 are provided on the upper inner wall of the sleeve 1211 and the top of the slide rod 1212. The magnetic poles of the two magnet blocks 1213 facing each other are the same. The rubber strip at the bottom of the pressure plate 122 is elastic, which can prevent rigid stress from damaging the surface of the photosensitive resin sheet; When the longitudinal connecting frame 120 is raised to the high position, the slide rod 1212 is fully extended from the sleeve 1211, and the distance between the two magnet blocks 1213 is at its maximum. During the pressing process, the slide rod 1212 retracts into the sleeve 1211, causing the two magnet blocks 1213 to approach each other. This causes the two magnet blocks 1213 to repel each other. Through the repulsive force between the same poles of the two magnet blocks 1213, the slide rod 1212 can push the pressure plate 122 to generate a pressing force. This design uses magnetic force as the elastic force of the elastic connector 121, which can effectively press the photosensitive resin sheet.
