Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to an automatic dry film peeling device. Background Technology

[0002] In circuit board manufacturing, dry film mainly consists of photoresist composed of photosensitive resin containing photoinitiators, which forms resist patterns through ultraviolet exposure. In dry film lithography, to protect the dry film from physical damage, chemical contamination, and environmental interference, a transparent or semi-transparent protective film made of polyester film (PET) is used as a carrier to protect it. Furthermore, in the DES (Developing, Etching, and Stripping) and copper plating development processes, the protective film protecting the dry film needs to be removed. In traditional technologies, due to various reasons, the loading of materials in these two processes has been slow to be automated, and the protective film has always been removed manually. This not only fails to effectively prevent errors but also requires a large amount of manual operation, resulting in high labor costs, low efficiency, and unreliable film removal quality.

The dry film, except for one side (e.g., the front), is flipped over and transferred and positioned on a second film-tearing positioning table. Then, the second film-tearing positioning table begins to peel off the protective film on the other side (e.g., the reverse side). A second film-tearing clamping structure then holds the peeled-off protective film on the other side (e.g., the reverse side) and tears it off, thus removing the protective film from both sides of the dry film. The unloading mechanism then picks up the peeled dry film from the second film-tearing positioning table and stores it in a lifting unloading bin. This automatic dry film peeling device provides automatic peeling of the protective film from both sides of the dry film, saving labor costs, improving production efficiency, and ensuring peeling quality and product quality.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] like Figures 1 to 3 As shown, this utility model proposes an automatic dry film peeling protective film device 10, including a frame mechanism 100, and a feeding mechanism 200, a first film peeling mechanism 300, a second film peeling mechanism 400, and a discharging mechanism 500 sequentially arranged on the frame mechanism 100. The feeding mechanism 200 stores the dry film to be peeled and feeds it to the first film peeling mechanism 300. The first film peeling mechanism 300 peels off the protective film on one side of the dry film to be peeled, and the second film peeling mechanism 400 peels off the protective film on the other side. The discharging mechanism 500 unloads the dry film after peeling both sides and stores the peeled dry film. This automatic dry film peeling device can automatically peel off the protective film on both sides of the dry film, saving labor costs, improving production efficiency, and ensuring peeling quality and product quality.

[0038] Specifically, the frame mechanism 100 may include a frame base 110 and a worktable 120 disposed on the frame base 110. The worktable 120 is provided with a loading station, a first film-tearing station, a second film-tearing station, and a unloading station. Furthermore, the loading mechanism 200 may include a lifting loading bin 210 disposed at the loading station, and a loading and unloading structure 220 disposed between the loading station and the first film-tearing station, the loading and unloading structure 220 being located above the lifting loading bin 210. The lifting loading bin 210 of the loading mechanism 200 can store and move multiple sheets of dry film to be peeled, making it convenient for the loading and unloading structure 220 to retrieve the dry film from the lifting loading bin 210.

[0039] Furthermore, the first film-tearing mechanism 300 may include a first film-tearing positioning table 310 and a first film-tearing clamping structure 320 disposed at the first film-tearing station, with the first film-tearing clamping structure 320 located above the first film-tearing positioning table 310. The dry film to be peeled can be transferred to the first film-tearing positioning table 310 of the first film-tearing mechanism 300 via the loading and unloading structure 220. The first film-tearing positioning table 310 of the first film-tearing mechanism 300 can position and start the dry film to be peeled, and the protective film starting on one side (such as the front) of the dry film can be clamped by the first film-tearing clamping structure 320, and the protective film on one side (such as the front) of the dry film can be peeled off.

[0040] Furthermore, the second film-tearing mechanism 400 may include a second film-tearing positioning table 310 and a second film-tearing clamping structure 420 disposed at the second film-tearing station, and a dry film flipping structure 430 disposed between the first film-tearing station and the second film-tearing station. The second film-tearing clamping structure 420 is located above the second film-tearing positioning table 410, and the dry film flipping structure 430 corresponds to and cooperates with the first film-tearing positioning table 310 and the second film-tearing positioning table 410. The dry film flipping structure 430 of the second film-tearing mechanism 400 flips the dry film with one side (e.g., the front side) of the protective film torn off on the first film-tearing positioning table 310, and transfers and positions the flipped dry film on the second film-tearing positioning table 410. Then, the protective film on the other side (e.g., the reverse side) of the dry film can be started through the second film-tearing positioning table 410, and the protective film started on the other side (e.g., the reverse side) of the dry film can be held by the second film-tearing clamping structure 420, and the protective film on the other side (e.g., the reverse side) of the dry film can be torn off, thereby removing the protective film on both sides of the dry film.

[0041] Furthermore, the unloading mechanism 500 may include a lifting unloading bin 510 located at the unloading station, and an unloading and picking structure 520 located between the unloading station and the second film-tearing station, with the unloading and picking structure 520 positioned above the lifting unloading bin 510. The unloading and picking structure 520 of the unloading mechanism 500 can be used to pick up dry film with both sides peeled from the second film-tearing positioning table 410, and store the peeled dry film in the lifting unloading bin 510 for storage.

[0042] Furthermore, the loading station and the first film-tearing station are arranged horizontally on one side of the workbench 120, while the unloading station and the second film-tearing station are arranged horizontally on the other side of the workbench 120. The loading and unloading stations are arranged side by side, as are the first and second film-tearing stations. This arrangement allows the loading mechanism 200 and the unloading mechanism 500 to be arranged side by side, and the first and second film-tearing mechanisms 300 and 400 to be arranged side by side. The loading mechanism 200, the first film-tearing mechanism 300, the second film-tearing mechanism 400, and the unloading mechanism 500 are arranged in a U-shape, which not only facilitates material flow but also makes the equipment layout compact and saves space. Alternatively, the loading station, the first film-tearing station, the second film-tearing station, and the unloading station can also be arranged in a straight line.

[0043] Furthermore, both the lifting-type loading bin 210 of the loading mechanism 200 and the lifting-type unloading bin 510 of the unloading mechanism 500 may include a lifting support frame 212 located below the worktable 120, and a storage bin 214 located above the worktable 120 and connected to the lifting support frame 212. Materials (including dry film to be peeled and dry film after peeling) can be stacked and stored through the storage bin 214, while the lifting support frame 212 can lift and transfer the stacked materials in the storage bin 214, facilitating material discharge and collection.

[0044] Furthermore, such as Figures 2 to 5 As shown, the lifting support frame 212 may include a support base 2122 movably disposed below the worktable 120, a hopper lifting drive motor 2124 disposed on the support base 2122, a hopper lifting screw structure 2126 connected to the output shaft of the hopper lifting drive motor 2124, and a hopper lifting guide structure 2128 disposed on the support base 2122. The bottom of the storage bin 214 is connected to the hopper lifting screw structure 2126 and the hopper lifting guide structure 2128. The hopper lifting drive motor 2124 on the support base 2122 can drive the hopper lifting screw structure 2126, causing the hopper lifting screw structure 2126 to move the storage hopper 214 or the bottom of the storage hopper 214 up and down, thereby moving the material in the storage hopper 214 up and down; moreover, the hopper lifting guide structure 2128 can support and guide the bottom of the storage hopper 214, making the lifting and moving of the storage hopper 214 or the bottom of the storage hopper 214 stable and reliable.

[0045] Furthermore, the support base 2122 may include a lifting support seat protruding below the bottom surface of the workbench 120, and a motor mounting base located below the lifting support seat. The hopper lifting drive motor 2124 is mounted on the motor mounting base. One end of the drive screw of the hopper lifting screw structure 2126 is connected to the output end of the hopper lifting drive motor 2124, and the other end is rotatably mounted on the bottom of the storage hopper 214. The driven nut of the hopper lifting screw structure 2126 is mounted on the lifting support seat. This allows the hopper lifting drive motor 2124 to drive the drive screw to rotate, causing the drive screw to rotate relative to the driven nut on the lifting support seat, thereby causing the drive screw to move up and down to lift or move the storage hopper 214 or its bottom. Moreover, the hopper lifting guide structure 2128 may include multiple hopper lifting guide rods protruding from the motor mounting base. All multiple hopper lifting guide rods are movably mounted on the lifting support seat, and their tops are all connected to the bottom of the storage hopper 214.

[0046] In addition, the storage hopper 214 may include a hopper lifting port 2142 located on the top surface of the workbench 120, a hopper side frame 2144 surrounding the hopper lifting port 2142, and a hopper bottom plate 2146 movably located in the middle of the hopper side frame 2144. A hopper lifting screw structure 2126 is connected to the middle of the bottom of the hopper bottom plate 2146, and a lifting guide structure is connected to the periphery of the bottom of the hopper bottom plate 2146. A storage cavity is formed between the annular hopper side frame 2144 and the hopper bottom plate 2146, which can be used to store dry film to be peeled or dry film that has already been peeled. The lifting screw structure 2126 of the lifting support frame 212 can lift and move the bottom plate 2146 of the storage hopper 214, thereby lifting and moving the material stored in the storage chamber, which is convenient for taking material from the top of the storage hopper 214 through the loading and unloading structure 220 or unloading material from the top of the storage hopper 214 through the unloading and unloading structure 520.

[0047] Furthermore, the hopper side frame 2144 may include an annular side frame base plate surrounding the top surface of the hopper lifting port 2142, and multiple side frame hopper columns (or multiple side frame hopper plates) protruding from the annular side frame base plate, the multiple side frame hopper columns (or multiple side frame hopper plates) being arranged in a ring. In addition, the hopper bottom plate 2146 may include a bottom plate connecting plate and a bottom plate main plate disposed on the bottom plate connecting plate. The top of the drive screw of the hopper lifting screw structure 2126 is rotatably disposed on the bottom plate connecting plate, and the tops of the multiple hopper lifting guide rods of the hopper lifting guide structure 2128 may also be connected to the bottom plate connecting plate. The bottom plate main plate may be correspondingly disposed with the hopper lifting port 2142.

[0048] In addition, such as Figure 2 and Figure 5 As shown, the loading and unloading structure 220 of the loading mechanism 200 and the unloading and unloading structure 520 of the unloading mechanism 500 can both include a material handling side frame 222 on the worktable 120, a material handling lateral movement drive 224 on the material handling side frame 222, a material handling lifting drive 226 on the material handling lateral movement drive 224, and a material handling suction plate 228 on the material handling lifting drive 226. The material handling lateral movement drive 224 can extend between the loading station and the first film-tearing station, or extend between the unloading station and the second film-tearing station. The material handling suction plate 228 can be located above the storage bin 214 and the first film-tearing positioning table 310, or above the storage bin 214 and the second film-tearing positioning table 410.

[0049] The material handling side frame 222 can support the loading and unloading structure 220 or the unloading and unloading structure 520 on the upper side of the storage bin 214, which facilitates the loading and unloading structure 220 to pick up materials or the unloading and unloading structure 520 to unload materials. Furthermore, the material handling lateral movement drive 224 of the feeding mechanism 200 can drive the material handling adsorption plate 228 to transfer the dry film to be torn from the storage bin 214 of the feeding mechanism 200 at the feeding station to the first film tearing positioning table 310 at the first film tearing station for film tearing; and the material handling lifting drive 226 of the feeding mechanism 200 can drive the material handling adsorption plate 228 to descend to the top of the storage bin 214 of the feeding mechanism 200 at the feeding station to grab the dry film to be torn, and can drive the material handling adsorption plate 228 to descend to the top surface of the first film tearing positioning table 310 when moving the dry film to be torn to the first film tearing station and place the dry film to be torn on the first film tearing positioning table 310.

[0050] Alternatively, the picking and placing transverse drive 224 of the unloading mechanism 500 can drive the picking and placing suction plate 228 to transfer the dry film that has been torn on the second film-tearing positioning table 410 at the second film-tearing station to the storage bin 214 of the unloading mechanism 500 at the unloading station for storage; while the picking and placing lifting drive 226 of the unloading mechanism 500 can drive the picking and placing suction plate 228 to descend to the top surface of the second film-tearing positioning table 410 and grab the dry film that has been torn on the first film-tearing positioning table 310. When the dry film that has been torn is transferred from the second film-tearing station to the unloading station, it can descend to the top of the storage bin 214 of the unloading mechanism 500 at the unloading station and place the dry film that has been torn in the storage bin 214.

[0051] Furthermore, the material handling lateral movement drive 224 may include a first motor linear drive module 2242 disposed on the side of the top of the material handling side frame 222; the material handling lifting drive 226 may include a material handling lifting seat 2262 slidably connected to the first motor linear drive module 2242, a material handling lifting bracket 2264 protruding from the material handling lifting seat 2262, a material handling drive cylinder 2266 disposed at the end of the material handling lift bracket 2264, and a material handling lifting guide frame 2268 disposed on the material handling lift bracket 2264. Moreover, the material handling suction plate 228 includes a material handling connecting plate 2282 connected to the drive ends of the material handling lifting guide frame 2268 and the material handling drive cylinder 2266, a material handling main plate 2284 disposed at the bottom of the material handling connecting plate 2282, and a plurality of vacuum material handling nozzles 2286 disposed around the material handling main plate 2284. The first motor linear drive module 2242 can drive the pick-and-place lifting seat to move horizontally along the worktable 120, while the pick-and-place drive cylinder 2266 can drive the pick-and-place main board 2284 to move vertically. The multiple vacuum pick-and-place nozzles 2286 on the pick-and-place main board 2284 can adsorb and grab the dry film from all sides.

[0052] In addition, such as Figure 2 and 7 As shown, the first film-tearing positioning table 310 of the first film-tearing mechanism 300 and the second film-tearing positioning table 410 of the second film-tearing mechanism 400 may each include a film-tearing positioning seat 312 provided on the worktable 120, a film-tearing positioning plate 314 provided on the film-tearing positioning seat 312, and a protective film ejector pin structure provided on the film-tearing positioning plate 314. The film-tearing positioning plate 314 corresponds vertically to the loading and unloading structure 220, or the unloading and unloading structure 520, or the first film-tearing clamp structure 320, or the second film-tearing clamp structure 420. The dry film to be peeled can be placed on the peeling positioning plate 314 on the peeling positioning seat 312 of the first peeling positioning table 310 through the feeding and picking structure 220, and the dry film to be peeled can be positioned. Then, the protective film on one side of the dry film to be peeled can be lifted and started by the protective film ejector pin structure on the peeling positioning plate 314 of the first peeling positioning table 310. Then, the protective film after starting can be clamped and peeled off by the first peeling clamping structure 320, and the protective film on one side of the dry film can be removed.

[0053] Furthermore, through the dry film flipping structure 430 between the first film-tearing positioning table 310 and the second film-tearing positioning table 410, the dry film with one side of the protective film torn off on the first film-tearing positioning table 310 can be flipped and transferred to the film-tearing positioning plate 314 on the film-tearing positioning seat 312 of the second film-tearing positioning table 410. The film-tearing positioning plate 314 of the second film-tearing positioning table 410 positions the dry film with one side torn off. Similarly, the protective film ejector pin structure on the film-tearing positioning plate 314 of the second film-tearing positioning table 410 can then be used to lift up the protective film on the other side of the dry film with one side torn off on the film-tearing positioning plate 314. Then, the protective film after lifting can be clamped and torn off through the second film-tearing clamping structure 420 to remove the protective film on the other side of the dry film. Then, the dry film with the protective film removed from both sides on the film-tearing positioning plate 314 of the second film-tearing positioning table 410 can be transferred to the storage bin 214 of the unloading mechanism 500 for storage through the unloading and picking structure 520.

[0054] Furthermore, the film-tearing positioning seat 312 may include one positioning support on each side of the first or second film-tearing station on the worktable 120; the film-tearing positioning plate 314 may include a film-tearing main plate 3142 on the two positioning supports, a film-tearing adsorption plate 3144 on the film-tearing main plate 3142, and multiple vacuum adsorption holes on the film-tearing adsorption plate 3144, through which the dry film can be adsorbed and positioned on the film-tearing positioning plate 314. Moreover, multiple positioning protrusions may be provided on the film-tearing main plate 3142 or the film-tearing adsorption plate 3144 to position the dry film. The protective film ejector pin structure (not shown in the figure) may include an ejector pin lifting drive component located at the bottom (or inside) of the film-tearing main plate 3142, and an ejector pin connected to the ejector pin lifting drive component. After the dry film is adsorbed and positioned by the film-tearing positioning plate 314, the top film needle can be driven out from the film-tearing main plate by the ejector pin lifting drive to lift the edge of the protective film on the top surface of the dry film, so that the edge of the protective film can be clamped by the first film-tearing clamping structure 320 and the second film-tearing clamping structure 420. Moreover, the ejector pin lifting drive can be set as a lifting drive cylinder.

[0055] In addition, such as Figures 8 to 9As shown, both the first film-tearing clamp structure 320 and the second film-tearing clamp structure 420 may include a film-tearing side frame 322 disposed on the worktable 120, a film-tearing lateral movement drive 324 disposed on the film-tearing side frame 322, a film-tearing lifting drive 326 disposed on the film-tearing lateral movement drive 324, and a film-tearing clamp 328 disposed on the film-tearing lifting drive 326. The film-tearing clamp 328 is located above the film-tearing positioning plate 314. The film-tearing lateral movement drive 324 can drive the film-tearing clamp 328 to move horizontally above the first film-tearing station or the second film-tearing station. This not only aligns the film-tearing clamp 328 with the beginning of the protective film of the dry film on the first film-tearing positioning table 310 or the second film-tearing positioning table 410, but also allows the film-tearing clamp 328 holding the beginning of the protective film of the dry film to move and tear the film. Moreover, the film-tearing lifting drive 326 can drive the film-tearing clamp 328 to move up and down, so that the film-tearing clamp 328 is closer to or further away from the beginning of the protective film of the dry film.

[0056] Furthermore, the film-tearing lateral movement drive 324 may include a second motor linear drive module 3242 disposed on the side of the top of the film-tearing side frame 322; the film-tearing lifting drive 326 may include a film-tearing lifting seat 3262 slidably connected to the second motor linear drive module 3242, and a film-tearing lifting drive cylinder 3264 disposed on the side of the film-tearing lifting seat 3262, with the film-tearing clamp 328 disposed at the drive end of the film-tearing lifting drive cylinder 3264. The second motor linear drive module 3242 can drive the film-tearing clamp 328 to reciprocate linearly above the first or second film-tearing station, and the film-tearing lifting drive cylinder 3264 can drive the film-tearing clamp 328 to move up and down.

[0057] Furthermore, the film-tearing clamp 328 may include a clamp base 3282 disposed on the drive end of the film-tearing lifting drive cylinder 3264 of the film-tearing lifting drive member 326, a clamp telescopic drive member 3284 disposed on the clamp base 3282, a clamp telescopic linkage structure 3286 connected to the clamp telescopic drive member 3284, a telescopic clamp 3288 disposed on the clamp telescopic linkage structure 3286, a clamp connecting rod 3285 disposed on the clamp base 3282, and a fixed clamp 3287 head disposed on the clamp connecting rod 3285. The fixed clamp 3287 head and the telescopic clamp 3288 are correspondingly engaged and used to clamp the protective film on the dry film. The clamp telescopic drive component 3284 can drive the clamp telescopic linkage structure 3286 to move the telescopic clamp 3288 vertically, so that the telescopic clamp 3288 moves closer to or away from the fixed clamp 3287 head on the clamp connecting rod 3285, so that the telescopic clamp 3288 and the fixed clamp 3287 head can clamp or release the beginning of the protective film on the dry film.

[0058] Furthermore, the clamp telescopic drive component 3284 may include a clamp drive bracket 32842, a clamp telescopic drive cylinder 32844 disposed on the clamp drive bracket 32842, a clamp telescopic drive plate 32846 connected to the drive end of the clamp telescopic drive cylinder 32844, a clamp telescopic guide plate 32848 disposed on the clamp base 3282, and a clamp telescopic guide rod 32849 disposed between one side of the clamp telescopic guide plate 32848 and one side of the clamp drive bracket 32842, with one side of the clamp telescopic drive plate 32846 movably sleeved in the middle of the clamp telescopic guide rod 32849. Moreover, the end of the chuck connecting rod 3285 is located on the other side of the clamp drive bracket 32842, and moves sequentially through the other side of the clamp telescopic drive plate 32846, the other side of the clamp telescopic guide plate 32848, and the clamp base 3282, and protrudes below the bottom of the clamp base 3282, so that the chuck connecting rod 3285 can be used as a guide rod at the same time.

[0059] Furthermore, the chuck telescopic linkage structure 3286 may include a telescopic hinge rod 32862 hinged to the bottom of the clamp telescopic drive plate 32846, a telescopic main linkage 32864 hinged to the telescopic hinge rod 32862, and a first hinge seat 32866 and a second hinge seat 32868 respectively provided on the clamp telescopic guide plate 32848 and the clamp base 3282. The telescopic main linkage 32864 moves through the clamp telescopic guide plate 32848 and the clamp base 3282, and is hinged to the first hinge seat 32866 and the second hinge seat 32868 respectively, and protrudes below the bottom of the clamp base 3282. The film-tearing lifting drive cylinder 32844 can drive the clamp telescopic drive plate 32846 to move up and down, so that the clamp telescopic drive plate 32846 drives the telescopic hinge rod 32862 to rotate, and the telescopic hinge rod 32862 drives the telescopic main connecting rod 32864 to move telescopically.

[0060] Furthermore, both the telescopic clamp 3288 and the fixed clamp 3287 can include a clamp connecting portion located at the bottom end of the telescopic main connecting rod 32864 or the bottom end of the clamp connecting rod 3285, a clamp connecting plate located on the clamp connecting portion, and a clamping plate bent at the end of the clamp connecting plate. The clamping plates of the telescopic clamp 3288 and the fixed clamp 3287 are arranged correspondingly above and below each other, and can move closer or further apart to clamp or release the beginning of the protective film. Moreover, the clamping plate of the fixed clamp 3287 can be a wedge-shaped clamping plate, and the clamping plate of the telescopic clamp 3288 can be a flat clamping plate, which facilitates guiding and clamping the beginning of the protective film.

[0061] In addition, such as Figure 1 , Figure 2 , Figure 10As shown, the dry film flipping structure 430 may include a flipping drive motor 432 and a flipping base 434 mounted on the worktable 120, a flipping shaft 436 rotatably mounted on the flipping base 434 and connected to the output shaft of the flipping drive motor 432, and a flipping adsorption plate 438 mounted on the flipping shaft 436. The flipping shaft 436 is located between the first film-tearing station and the second film-tearing station. The flipping adsorption plate 438 is shared with the film-tearing adsorption plate of the first film-tearing positioning table 310 and corresponds to and cooperates with the second film-tearing positioning table 410. The flipping drive motor 432 can drive the flipping shaft 436 to rotate, so that the flipping shaft 436 drives the flipping adsorption plate 438 (i.e., the film-tearing adsorption plate of the first film-tearing positioning table 310) to rotate between the first film-tearing station and the second film-tearing station. Thus, the flipping adsorption plate 438 can be used as the film-tearing adsorption plate of the first film-tearing positioning table 310, and the dry film with one side torn on the first film-tearing positioning table 310 can be flipped and moved onto the first film-tearing positioning table 310.

[0062] When the flipping adsorption plate 438 serves as the film-tearing adsorption plate of the first film-tearing positioning stage 310, it can overlap with the film-tearing main board to adsorb and position the dry film to be peeled. Moreover, after one side of the dry film is peeled off by the first film-tearing positioning stage 310, the flipping adsorption plate 438 (i.e., the film-tearing adsorption plate of the first film-tearing positioning stage 310) can be rotated by the flipping drive motor 432. This flips the dry film adsorbed on the film-tearing adsorption plate of the first film-tearing positioning stage 310 and places the flipped dry film on the film-tearing adsorption plate of the second film-tearing positioning stage 410, so that the other side of the dry film that has not been peeled is facing up, so as to remove the protective film on the other side of the dry film that has not been peeled.

[0063] In addition, the workbench 120 is equipped with a waste material station near the first and second film-tearing stations. Furthermore, the waste material station can be equipped with a waste material receiving box 600 and a receiving cart 700 for carrying and transporting the waste material receiving box 600. After the protective film on the dry film is removed, the protective film waste can be collected in the waste material receiving box 600, and the receiving cart 700 can carry and transport the waste material and the waste film, which is simple and convenient.
