Description

Technical Field

[0001] This utility model relates to the field of photosensitive dry film technology, specifically a photosensitive dry film winding device. Background Technology

[0002] Photosensitive dry film refers to an etch-resistant or electroplating-resistant material whose solubility changes upon irradiation or radiation such as ultraviolet light, electron beams, ion beams, and X-rays. It is a core process material widely used in the manufacture of various electronic information products. After processing, photosensitive dry film often needs to be wound using a winding device.

[0003] However, current photosensitive dry film winding devices suffer from operational inconvenience. To remove the wound photosensitive dry film, the take-up roller must first be detached from the support, then the photosensitive dry film must be removed from the take-up roller, and finally the take-up roller must be reinstalled on the support. This entire process is quite cumbersome, reducing production efficiency. Furthermore, existing winding devices primarily rely on the rotation of the crimping roller to wind the photosensitive dry film, which can easily result in insufficiently tight winding.

[0017] 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.

[0018] 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.

[0019] Please see Figures 1-4This utility model provides a photosensitive dry film winding device, including a housing 1, with doors 2 hinged to both the front and back of the housing 1, and handles provided on the doors 2. A winding mechanism 3 is provided inside the housing 1, comprising two first support frames 301 and a winding roller 304. One end of the roller shaft of the winding roller 304 is rotatably connected to a bearing on one of the two first support frames 301, and a driven gear 303 is mounted on the roller shaft of the winding roller 304 between the two first support frames 301. A driving gear (not shown in the figure) meshes below the driven gear 303, and the driving gear is connected to the output end of a rotary motor 302, which is mounted on one of the first support frames 301. Thus, the rotary motor 302, through the interaction of the gears, can drive the winding roller 304 to rotate, thereby winding the photosensitive dry film 7.

[0020] Please see Figure 3 and Figure 4A moving mechanism 6 is provided at the end of the take-up roller 304 away from the take-up mechanism 3. The moving mechanism 6 includes an electric push rod 605 and an electric telescopic rod 601. The electric telescopic rod 601 is mounted on the inner wall of the housing 1 via a mounting plate. A movable frame 604 is fixedly connected to the output end of the electric telescopic rod 601, and the electric push rod 605 is mounted on the side of the movable frame 604 away from the electric telescopic rod 601. A second support frame 606 is fixedly connected to the output end of the electric push rod 605, and the side of the second support frame 606 is slidably engaged with the movable frame 604 via a slider. A second sleeve 607 is rotatably connected to the second support frame 606; wherein, the second support frame 606 can be rotatably connected to the second sleeve 607 by means of a bearing. The electric push rod 605 is used to drive the second support frame 606 to move along the axial direction of the take-up roller 304, and the electric telescopic rod 601 is used to drive the electric push rod 605 and the second support frame 606 to move along the radial direction of the take-up roller 304. Therefore, the moving mechanism 6 can drive the other end of the second sleeve 607 to connect with or separate from the end of the take-up roller 304's shaft away from the take-up mechanism 3. When the second sleeve 607 is connected to the take-up roller 304's shaft, the second sleeve 607 is sleeved on the take-up roller 304's shaft; at this time, the second sleeve 607 plays a supporting role for the take-up roller 304, making the take-up roller 304 rotate more smoothly; after the photosensitive dry film 7 of a specified thickness has been wound on the take-up roller 304, the operator can open the box door 2 and cut the photosensitive dry film 7 with a paper cutter or scissors, and then use... After the tape is used to seal the edges, the electric push rod 605 drives the second sleeve 607 to separate from the roller shaft of the take-up roller 304. Then, the first electric telescopic rod 601 moves the movable frame 604 to one side. At this time, the operator can directly remove the photosensitive dry film 7 from the take-up roller 304. Therefore, the cooperation between the electric push rod 605 and the electric telescopic rod 601 facilitates the connection between the second sleeve 607 and the roller shaft of the take-up roller 304, thereby facilitating the installation and disassembly of the second sleeve 607 and the take-up roller 304, and thus facilitating the removal of the wound photosensitive dry film 7.

[0021] Preferably, the housing 1 is further provided with a guide frame 603. The output end of the electric telescopic rod 601 passes through the guide frame 603 and is fixedly connected to the movable frame 604. Guide rods 602 are provided on both sides of the output end of the electric telescopic rod 601. One end of the guide rod 602 is fixedly connected to the movable frame 604, and the other end of the guide rod 602 is slidably engaged with the movable frame 604. Thus, when the electric telescopic rod 601 extends or retracts, it will drive the movable frame 604 to move along the axial direction of the guide rod 602. At this time, the guide rod 602 plays a guiding and supporting role, which helps the movable frame 604 move more smoothly.

[0022] It should be noted that a cutting mechanism can also be set inside the housing 1 to automatically cut the wound photosensitive dry film 7. The specific structure of the cutting mechanism is not specifically limited in this application. As long as the automatic cutting of the photosensitive dry film 7 can be achieved, it is within the protection scope of this application.

[0023] Please continue reading. Figure 3 A pressing mechanism 4 is also provided inside the housing 1, which is used to press against the photosensitive dry film 7.

[0024] Specifically, the pressing mechanism 4 includes a fixed frame 401, within which a movable block 403 is slidably fitted. The upper surface of the movable block 403 is connected to the top wall of the fixed frame 401 via a spring 402, and a support rod 404 is mounted on the lower surface of the movable block 403. Two support rods 404 can be provided, and their bottom ends are rotatably connected to a pressing roller 405. Under the action of the spring 402, the lower surface of the pressing roller 405 presses against the photosensitive dry film 7, thereby pressing the wound photosensitive dry film 7 tightly, making the photosensitive dry film 7 wound on the take-up roller 304 compact.

[0025] Please see Figures 1-3 The housing 1 is also equipped with a drying mechanism 5, which includes a drying chamber 501. The top and bottom walls of the drying chamber 501 are mounted on a support plate 504, which is installed on the front surface of the housing 1. An electric heating element 503 is installed inside the drying chamber 501. An air inlet pipe 502 and an air outlet pipe 505 are fixedly connected to the drying chamber 501. A fan 506 is installed on the air inlet pipe 502. One end of the air inlet pipe 502, away from the drying chamber 501, extends into the housing 1. Air outlets are spaced apart on the air inlet pipe 502 located inside the housing 1. Two air inlet pipes 502 are provided, located on the upper and lower sides of the photosensitive dry film 7, respectively. After the fan 506 and the electric heating element 503 are started, the fan 506 blows hot air into the air outlet 505, and blows it onto the surface of the photosensitive dry film 7 through the air outlet on the air outlet 505, thereby drying the surface of the photosensitive dry film 7. Since the air inlet duct 502 is located on the upper and lower sides of the photosensitive dry film 7, and the air outlet is spaced apart on the air outlet, the surface of the photosensitive dry film 7 can be dried more evenly, thereby efficiently removing the solvent remaining in the photosensitive dry film 7 during the coating process and effectively avoiding bubble defects in the exposure process.

[0026] Preferably, a first sleeve 507 is fitted onto the air inlet pipe 502, and the first sleeve 507 is connected to the inner wall of the housing 1 via a fixing rod 508. By providing the first sleeve 507 and the fixing rod 508, the air inlet pipe 502 is fixed.

[0027] Preferably, the housing 1 is further provided with a guide roller 8, which is located at the feed inlet of the housing 1. After the photosensitive dry film 7 enters the housing 1 through the feed inlet, the guide roller 8 guides the photosensitive dry film 7.
