Description

Technical Field

[0001] This utility model relates to the field of photosensitive dry film production technology, specifically to an anti-deviation cutting machine for photosensitive dry film production. Background Technology

[0002] Photosensitive dry film typically consists of three parts: a PE protective film, a polyester film, and a photoresist film. The photoresist film is the main component of the photosensitive dry film, the polyester film serves as a carrier for coating, and the PE protective film acts as a protective layer, primarily functioning to isolate oxygen and prevent mechanical scratches. After the photosensitive dry film is manufactured, it needs to be cut.

[0003] However, most traditional cutting mechanisms do not restrain the photosensitive dry film during the cutting process, leading to easy movement of the dry film and uneven cuts, thus affecting the production quality of the dry film. Although a few cutting mechanisms take restraint of the photosensitive dry film into account during the cutting process, the operation method is not convenient enough. They require first fixing the photosensitive dry film to be cut with a restraining mechanism, and then operating the cutting mechanism to cut it, making the whole process relatively cumbersome. Therefore, we propose an anti-deviation cutting machine for photosensitive dry film production. Utility Model Content

[0004] The purpose of this invention is to improve and innovate upon the shortcomings and problems existing in the background technology, and to provide an anti-deviation cutting machine for photosensitive dry film production.

[0005] An anti-deviation cutting machine for photosensitive dry film production includes:

[0006] frame;

[0007] An unwinding roller, which is disposed at one end of the frame, is used to output photosensitive dry film;

[0008] A pressing mechanism, comprising a lower pressing roller and an upper pressing roller, wherein the lower pressing roller and the upper pressing roller are used to press the photosensitive dry film;

[0009] A conveying mechanism is used to drive the lower or upper pressure roller to rotate in order to convey the photosensitive dry film forward.

[0010] A cutting mechanism includes a lifting plate, on which a cutting blade is mounted. Pressure plates are provided on both sides of the cutting blade. The pressure plates are mounted on the lifting plate via elastic elements. The lifting plate moves up and down under the action of a driving mechanism.

[0011] A further embodiment is that an electric heating tube sleeve is installed on the lower surface of the lifting plate, an electric heating tube is sleeved inside the electric heating tube sleeve, and the cutting blade is installed on the lower surface of the electric heating tube sleeve.

[0012] A further embodiment is that the elastic element includes a sleeve, a movable rod is slidably fitted inside the sleeve, the bottom end of the movable rod is fixedly connected to the pressure plate, and the top end of the movable rod is fixedly connected to the top wall inside the sleeve through a second spring.

[0013] A further embodiment is that the frame is provided with a worktable corresponding to the cutting mechanism, and the worktable has a strip groove corresponding to the cutting blade.

[0014] A further embodiment is that the pressing mechanism further includes a slider rotatably connected to both ends of the upper pressing roller and a second support plate rotatably connected to both ends of the lower pressing roller. The outer surface of the slider is slidably engaged with the guide rod, and the top end of the slider is connected to the top plate through a first spring.

[0015] A further embodiment is that the conveying mechanism includes a motor, the output end of which is fixedly connected to a drive wheel, the drive wheel is connected to a driven wheel via a belt, and the driven wheel is installed at one end of the lower pressure roller.

[0016] A further embodiment is that the frame is also equipped with a collection frame, which is used to receive the cut photosensitive dry film.

[0017] A further option is to provide several guide rollers on the frame, which are used to guide the photosensitive dry film.

[0018] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model uses an electric push rod to drive the pressure plate and the cutting blade to move downwards at the same time, so that the pressure plate first contacts the photosensitive dry film on the worktable, thereby restricting the photosensitive dry film to be cut, and then the cutting blade contacts the photosensitive dry film to cut the photosensitive dry film. It is not necessary to operate the pressure plate to press the photosensitive dry film first, and then operate the cutting blade to cut the photosensitive dry film; so that the cutting mechanism can prevent the photosensitive dry film from moving during the cutting process, and is also very convenient to operate.

[0019] (2) This utility model can press the photosensitive dry film by the cooperation of the lower pressing roller, the upper pressing roller, the slider, the guide rod and the first spring, thereby increasing the contact friction force, so that the rotating lower pressing roller can convey the photosensitive dry film forward; moreover, the first spring can adapt to photosensitive dry films of different thicknesses, which is beneficial to improving the adaptability of the device; compared with pressing by driving the upper pressing roller up and down with an electric telescopic rod, this utility model can reduce the force during contact and prevent damage to the photosensitive dry film.

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1-4 This utility model provides an anti-deviation cutting machine for photosensitive dry film production, including a frame 1. The frame 1 is composed of several horizontal bars 101 and vertical bars 102. The horizontal bars 101 and vertical bars 102 can be paired up. A first support plate 5 is installed on the horizontal bar 101. The first support plates 5 are also paired up. A guide roller 4 or an unwinding roller 2 is rotatably connected between the two first support plates 5. The guide roller 4 is used to guide the photosensitive dry film 3. The unwinding roller 2 is wound with the photosensitive dry film 3 and is used to output the photosensitive dry film 3.

[0028] It should be noted that, since the horizontal bars 101 and the vertical bars 102 are paired, the photosensitive dry film 3 is allowed to extend from above the horizontal bars 101 to below the horizontal bars 101 between the corresponding horizontal bars 101.

[0029] like Figure 1 As shown, the unwinding roller 2 is located on the left side of the frame 1. The photosensitive dry film 3, guided by the guide roller 4, passes sequentially through the pressing mechanism 6 and the cutting mechanism 7. The pressing mechanism 6 includes a lower pressing roller 601 and an upper pressing roller 602, which are used to press the photosensitive dry film 3. Furthermore, in this embodiment, the lower pressing roller 601 is driven to rotate by the conveying mechanism 9. Since the lower pressing roller 601 and the upper pressing roller 602 are used to press the photosensitive dry film 3, the friction between the lower pressing roller 601 and the photosensitive dry film 3 is increased. When the conveying mechanism 9 drives the lower pressing roller 601 to rotate, the lower pressing roller 601 can convey the photosensitive dry film 3 forward.

[0030] For details, please refer to Figure 1 and Figure 2 The pressing mechanism 6 further includes a slider 604 rotatably connected to both ends of the upper pressing roller 602 and a second support plate 603 rotatably connected to both ends of the lower pressing roller 601. The outer surface of the slider 604 slides in contact with the outer surface of the guide rod 605 through an arc-shaped groove. The top end of the slider 604 is connected to the top plate 607 through a first spring 606. The top plate 607 is mounted on the top end of the guide rod 605, and the bottom end of the guide rod 605 and the second support plate 603 are mounted on the crossbar 101. Since the top of the slider 604 is connected to the top plate 607 via the first spring 606, when the photosensitive dry film 3 passes through the gap between the lower pressing roller 601 and the upper pressing roller 602, under the action of the first spring 606, the upper pressing roller 602 cooperates with the lower pressing roller 601 to press the photosensitive dry film 3, thereby increasing the contact friction. Moreover, the first spring 606 can adapt to photosensitive dry films 3 of different thicknesses, which is beneficial to improving the adaptability of the device. Compared with pressing by driving the upper pressing roller 602 up and down with an electric telescopic rod, this utility model can reduce the force during contact and prevent damage to the photosensitive dry film 3.

[0031] Please continue reading. Figure 2 The conveying mechanism 9 includes a motor 901, the output end of which is fixedly connected to a drive wheel 902. The motor 901 is mounted on the crossbar 101 via a motor mounting bracket. The drive wheel 902 is connected to a driven wheel 904 via a belt 903, and the driven wheel 904 is mounted on one end of the lower pressure roller 601. When the motor 901 drives the drive wheel 902 to rotate, the lower pressure roller 601 can be rotated via the belt 903 to convey the photosensitive dry film 3 forward.

[0032] Please see Figure 1 , Figure 3 and Figure 4 The frame 1 is equipped with a worktable 711 corresponding to the cutting mechanism 7. The cutting mechanism 7 includes a lifting plate 703, the upper surface of which is connected to the telescopic end of an electric push rod 702. The electric push rod 702 is mounted on a third support plate 701, which is mounted on a vertical rod 102. Under the driving action of the electric push rod 702, the lifting plate 703 can move up and down. An electric heating tube sleeve 704 is provided in the middle of the lower surface of the lifting plate 703. An electric heating tube 705 is sleeved inside the electric heating tube sleeve 704. A cutting blade 706 is installed on the lower surface of the electric heating tube sleeve 704. The heat generated by the electric heating tube 705 is transferred to the cutting blade 706 through the electric heating tube sleeve 704, so that the photosensitive dry film can be cut by the heated cutting blade 706. Sleeves 707 are provided at the four corners of the lower surface of the lifting plate 703. Movable rods 709 are slidably fitted inside the sleeves 707. A pressure plate 710 is fixedly connected to the bottom end of the two movable rods 709. The top end of the movable rods 709 is fixedly connected to the top wall inside the sleeves 707 through a second spring 708.

[0033] It should be noted that the height of the pressure plate 710 is lower than the height of the bottom of the cutting blade 706. When the electric push rod 702 drives the lifting plate 703 downward, the pressure plate 710 will first contact the photosensitive dry film 3 on the worktable 711, thereby restricting the photosensitive dry film 3 to be cut. Then, the electric push rod 702 continues to drive the lifting plate 703 downward, and the second spring 708 is further compressed. At this time, the cutting blade 706 contacts the photosensitive dry film 3 and cuts it. Since the pressure plate 710 and the cutting blade 706 move downward simultaneously when the electric push rod 702 of this utility model is activated, it is not necessary to first operate the pressure plate 710 to press down the photosensitive dry film 3 and then operate the cutting blade 706 to cut the photosensitive dry film 3. Therefore, the cutting mechanism of this utility model can not only prevent the photosensitive dry film 3 from moving during the cutting process, but is also very convenient to operate.

[0034] It should be further explained that, in order to achieve the cutting of the photosensitive dry film 3 to a specified length, an encoder can be installed on the upper end of the frame 1. The encoder can measure the length of the photosensitive dry film 3 being conveyed. During the process of the lower pressure roller 601 conveying the photosensitive dry film 3, the moving photosensitive dry film 3 simultaneously drives the measuring wheel of the encoder to rotate. The signal reflector on the measuring wheel continuously passes through the sensing area of ​​the signal generator, thereby triggering a signal to record the number of rotations. The encoder obtains the conveying length of the photosensitive dry film 3 by processing the electrical signal recording the number of rotations. It should be noted that the encoder measuring the moving length of the photosensitive dry film 3 through the measuring wheel is existing technology, and its specific process will not be described in detail here.

[0035] Preferably, the workbench 711 is provided with a strip groove 7111 corresponding to the cutting blade 706. The strip groove 7111 can prevent the cutting blade 706 from damaging the workbench 711.

[0036] Preferably, the frame 1 is also provided with a collection frame 8, which is located directly below the guide roller 4 on the right side of the frame 1, so that the collection frame 8 can easily receive the cut photosensitive dry film 3, thereby facilitating the collection of the cut photosensitive dry film 3.
