Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a novel hot roller laminating machine. Background Art

[0002] During the production process of flexible circuit boards (FPCs), dry film sometimes needs to be applied to the surface for protection. Traditionally, applying the dry film to the surface of a FPC using a hot roller laminator typically requires two operators: one person inserts the FPC product at the inlet of the machine, while the other uses a utility knife (or other cutting tool) to remove excess dry film from the product's edges at the outlet. This manual feeding and film cutting method is inefficient and requires high operator proficiency and the speed of film removal, significantly impacting product quality. Furthermore, the use of a utility knife (or other cutting tool) to assist in production also presents significant safety risks. Utility Model Content

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0036] like Figures 1 to 2 As shown, the present invention provides a novel hot roller laminator 10, comprising a flexographic plate feeding mechanism 100, a laminator 200, and a flexographic plate discharging mechanism 300, which are sequentially arranged. The flexographic plate feeding mechanism 100 automatically feeds the flexographic plate, automatically conveying a single flexographic plate to the laminator 200 for laminating a dry film on the surface of the flexographic plate. The resulting continuous flexographic plate material is then conveyed to the flexographic plate discharging mechanism 300, which automatically cuts the continuous flexographic plate material into film-coated flexographic plate products and discharges the film-coated flexographic plate products.

[0037] Specifically, if Figures 1 to 3As shown, the flex plate feeding mechanism 100 may include a feeding rack 110, a first flex plate bin 120 disposed on the feeding rack 110, a feeding and retrieving structure 130 disposed above the first flex plate bin 120, a feeding conveying structure 140 disposed below the feeding and retrieving structure, a flex plate cleaning structure 150 disposed on the feeding and retrieving structure 140, and a flex plate leveling structure 160 disposed at the end of the feeding and retrieving structure 140. The first flex plate bin 120 can be used to stack and store multiple flex plates to be laminated with dry film. The feeding and retrieving structure 130 can be used to grab and transfer the flex plates stored in the first flex plate bin 120 one by one to the feeding and retrieving structure 140. The feeding and retrieving structure 140 then conveys the individual flex plates to the laminator. Moreover, in the process of conveying the flexible plate through the feed conveying structure 140, the flexible plate can be cleaned when conveying it through the flexible plate cleaning structure 150, so that the subsequent film laminating effect is better; and, when conveying the flexible plate through the flexible plate flattening structure 160, the flexible plate can be flattened so that the flexible plate remains in a straight state and is conveyed into the laminating machine 200, which can further improve the film laminating effect.

[0038] Furthermore, the first flexi-plate bin 120 and the feed conveyor structure 140 are arranged side by side on the feed frame 110, and the feed pick-up structure 130 is arranged horizontally above the first flexi-plate bin 120 and the feed conveyor structure 140. The feed pick-up structure 130 can move horizontally between the first flexi-plate bin 120 and the feed conveyor structure 140, and transfers the flexi-plates from the first flexi-plate bin 120 to the feed conveyor structure 140. Furthermore, the feed pick-up structure 130 corresponds to the infeed side of the feed conveyor structure 140, and the flexi-plate cleaning structure 150 and the feed pick-up structure 130 are sequentially arranged horizontally on the discharge side of the feed conveyor structure 140, resulting in a compact and rationally designed overall structure of the flexi-plate feeding mechanism 100.

[0039] Furthermore, the first flexible plate bin 120 may include a bin plate lifting structure mounted on the feed frame 110, a bottom bin plate connected to the bin plate lifting structure, and multiple side limit plates surrounding the bottom bin plate. A storage cavity may be formed between the bottom bin plate and the surrounding side limit plates for storing multiple stacked flexible plates. Furthermore, during the unloading process, the bin plate lifting structure can be used to raise and lower the stacked flexible plates on the bottom bin plate, maintaining them at a predetermined height, facilitating access by the feed and reclaim mechanism 130.

[0040] Furthermore, the feeding and retrieving structure 130 may include a retrieving horizontal drive member 132 provided on the feeding frame 310, a retrieving lifting drive member 134 provided on the retrieving horizontal drive member 132, and a suction retrieving and unloading frame 136 provided on the retrieving lifting drive member 134. The retrieving horizontal drive member 132 may include a horizontal linear drive module extending above the first flexible plate bin 120 and the feeding conveying structure 140, the retrieving lifting drive member 134 may include a vertical linear drive module provided on the horizontal linear drive module, and the suction retrieving and unloading frame 136 may move horizontally and vertically under the drive of the horizontal linear drive module and the vertical linear drive module; furthermore, the suction retrieving and unloading frame 136 may include an adsorption frame provided on the vertical linear drive module, and a plurality of vacuum nozzles provided on the adsorption frame.

[0041] In addition, the feed conveying structure 140 can be configured as a roller conveyor. Figure 4 As shown, the flex plate cleaning structure 150 may include a cleaning frame 152 disposed on the feed frame 110, a cleaning drive 154 disposed on the cleaning frame 152, a driving cleaning roller 156 connected to the cleaning drive 154 and rotatable on the cleaning frame 152, a driven cleaning roller 158 disposed on the cleaning frame 152, and a driven roller lifting member 159 connected to the driven cleaning roller 158. A cleaning gap for the flex plate to pass through is formed between the driving cleaning roller 156 and the driven cleaning roller 158. The cleaning drive 154 can drive the driving cleaning roller 156 to rotate, so that the flex plate conveyed by the feed conveying structure 140 passes through the cleaning gap between the driving cleaning roller 156 and the driven cleaning roller 158, so that the driving cleaning roller 156 and the driven cleaning roller 158 clean the flex plate from both the upper and lower sides. Furthermore, the driven cleaning roller 158 can be raised and lowered by the driven roller lift 159 to adjust the width of the cleaning gap between the driving cleaning roller 156 and the driven cleaning roller 158, thereby adjusting the compacting and cleaning effect on the flexible plate. Furthermore, the driven roller lift 159 can include at least one lift drive cylinder or at least one lift drive motor mounted on the cleaning frame 152, and a roller lift bracket connected to the lift drive cylinder or the lift drive motor. The driven cleaning roller 158 is rotatably mounted on the roller lift bracket.

[0042] In addition, if Figure 5As shown, the flex plate leveling structure 160 may include a leveling frame 162 mounted on the feed frame 110, an upper leveling roller structure 164 and a lower leveling roller structure 166 mounted above and below the leveling frame 162, and a leveling conveyor belt 168 mounted on the leveling frame 162 and docked with the feed side of the laminator. Furthermore, a leveling gap is formed between the upper leveling roller structure 164 and the lower leveling roller structure 166. The entrance of the leveling gap corresponds to the end of the feed conveying structure 140, and the exit of the leveling gap corresponds to the leveling conveyor belt 168. After being cleaned by the flex plate cleaning structure 150, the flex plates are transported to the flex plate leveling structure 160 via the feed conveying structure 140. The plates enter the leveling gap between the upper leveling roller structure 164 and the lower leveling roller structure 166 through the entrance of the leveling gap, where each flex plate is leveled and made straight. After being leveled by the upper leveling roller structure 164 and the lower leveling roller structure 166, the flexible plate is transported from the outlet of the leveling gap to the leveling conveyor belt 168, and is transported to the feed side of the laminator 200 through the leveling conveyor belt 168, thereby transporting the leveled flexible plate to the laminator 200 and pressing the dry film on the surface of the flexible plate.

[0043] Furthermore, both the upper and lower leveling roller structures 164 and 166 may include a pressing drive structure 1644 disposed on the leveling frame 162, a pressing roller structure 1646 connected to the pressing drive structure 1644, and an entry / exit guide block 1648 disposed on the pressing roller structure 1646. The pressing drive structure 1644 can drive the pressing roller structures 1646 toward or away from each other, thereby tightening or loosening the flex plate. Furthermore, the pressing roller structure 1646 may include a main roller connected to the pressing drive structure 1644 and multiple sub-rollers disposed side by side on the leveling frame 162. The entry / exit guide blocks 1648 may be disposed on the sub-rollers. The pressing drive structure 1644 can drive the main roller to simultaneously apply pressure to the multiple sub-rollers, thereby compressing and leveling the flex plate from both sides as it passes between the two pressing roller structures 1646.

[0044] Furthermore, the compression drive structure 1644 may include a drive mounting block located on either side of the leveling frame 162, a compression lift drive cylinder located on each drive mounting block, and a compression mounting seat connected to each compression lift drive cylinder. The compression mounting seat is slidably mounted on the drive mounting block, and the main roller of the compression roller structure 1646 is rotatably mounted on the two compression mounting seats. Multiple entry and exit guide blocks 1648 extend side by side on the multiple sub-rollers, with a guide inlet and a guide outlet at each end of each entry and exit guide block 1648, respectively, to guide the flattened flex plate in and out of the leveling gap.

[0045] Furthermore, the laminator 200 can be equipped with a roll of dry film. After a single flexo sheet is flattened and transported to the laminator 200 by the flexo sheet leveling structure 160, the laminator 200 delivers a continuous dry film to the flexo sheet and applies the dry film to the flexo sheet using a hot roller. After multiple flexo sheets are sequentially applied to the continuous dry film, a continuous flexo sheet material is obtained. Furthermore, after obtaining the continuous flexo sheet material, the flexo sheet cutting and output mechanism 304 of the flexo sheet discharging mechanism 300 is required to cut the continuous flexo sheet material. Excess dry film is removed from the edges of each flexo sheet, leaving only the surface of each flexo sheet with dry film, while no excess dry film remains outside the sides of the flexo sheet, resulting in a single flexo sheet film product.

[0046] In addition, if Figure 1 、 Figure 2 、 Figure 6 As shown, the flexo plate discharging mechanism 300 may include a flexo plate buffer mechanism 302 connected to the discharging side of the laminator 200, and a flexo plate cutting and output mechanism 304 connected to the flexo plate buffer mechanism 302. Before the flexo plate cutting and output mechanism 304 discharges the continuous flexo plate material and cuts the dry film on the continuous flexo plate material, the flexo plate with the dry film applied (i.e., the continuous flexo plate material) may be transferred and transported by the flexo plate buffer mechanism 302, and the continuous flexo plate material may be buffered and cooled.

[0047] Furthermore, if Figures 6 and 7 As shown, the flexo plate buffer mechanism 302 may include a buffer rack 312, a feed guide roller structure 360 ​​and a discharge guide roller structure 370 respectively provided on the feed side and discharge side of the top of the buffer rack 312, a buffer roller structure 390 provided at the bottom of the buffer rack 312, and a drive roller structure 380 provided in the middle of the buffer rack 312. The feed guide roller structure 360 ​​and the discharge guide roller structure 370 provided on both sides of the top of the buffer rack 312, the drive roller structure 380 provided in the middle of the buffer rack 312, and the buffer roller structure 390 provided at the bottom of the buffer rack 312 form a U-shaped flexo plate buffer structure, which can buffer the continuous flexo plate material before cutting the dry film on the continuous flexo plate material.

[0048] The continuous flexible plate material can be guided from the top of the buffer rack 312 into the flexible plate buffer mechanism 302 through the feed guide roller structure 360, and the continuous flexible plate material can be pulled by the drive roller structure 380 to transport the flexible plate from the feed guide roller structure 360 ​​at the top of the buffer rack 312 to the buffer roller structure 390 at the bottom of the buffer rack 312. The continuous flexible plate material can be guided and transported from the bottom of the buffer rack 312 to the discharge guide roller structure 370 at the top of the buffer rack 312 through the buffer roller structure 390, and the continuous flexible plate material can be guided and transported to the flexible plate cutting output mechanism 304 through the discharge guide roller structure 370.

[0049] The drive roller structure 380 may include a roller drive structure 382 disposed on the buffer rack 312, and a drive roller 384 connected to the roller drive structure 382. The drive roller 384 is located in the middle of the buffer rack 312, near the feed side of the buffer rack 312. The roller drive structure 382 drives the drive roller 384 to rotate, causing the drive roller 384 to pull and guide the continuous flexographic material at the feed guide roller structure 360, actively moving the continuous flexographic material toward the buffer roller structure 390. Furthermore, the buffer roller structure 390 may include a roller lifting structure 392 disposed on each side wall of the buffer rack 312, and a buffer conveying roller 394 disposed on each roller lifting structure 392. The buffer conveying roller 394 is located between the feed guide roller structure 360 ​​and the discharge guide roller structure 370. The buffer conveying roller 394 can be raised and lowered by the roller lifting structure 392, and the height of the buffer conveying roller 394 can be adjusted, thereby adjusting the distance between the buffer conveying roller 394 and the feed guide roller structure 360 ​​and the discharge guide roller structure 370, thereby adjusting the length of the continuous flexible plate material cached on the U-shaped flexible plate buffer structure.

[0050] The specific structures of the feed guide roller structure 360 ​​and the discharge guide roller structure 370 are similar to those of the flexo plate cleaning structure 150 and will not be further described here. Furthermore, a feed guide gap is formed in the middle of the feed guide roller structure 360 ​​to guide the continuous flexo plate material into the flexo plate buffer mechanism 302; a discharge guide gap is formed in the middle of the discharge guide roller structure 370 to guide the continuous flexo plate material out of the flexo plate buffer mechanism 302. Furthermore, at least one intermediate transfer roller 314 may be provided between the feed guide roller structure 360 ​​and the buffer roller structure 390, and between the buffer roller structure 390 and the discharge guide roller structure 370, for intermediate transfer and tensioning of the continuous flexo plate material, ensuring smooth transportation of the continuous flexo plate material within the flexo plate buffer mechanism 302.

[0051] In addition, if Figure 6 、 Figure 8As shown, the flexible plate cutting output mechanism 304 may include a discharge rack 310, a discharge conveying structure 320 provided on the discharge rack 310 and docked with the flexible plate buffer mechanism 302, a dry film cutting structure 330 provided on the feed side of the discharge conveying structure 320, a discharge and picking structure 340 provided above the discharge conveying structure 320, and a second flexible plate bin 350 provided on the discharge rack 310 and correspondingly arranged above and below the discharge and picking structure 340. The continuous flexible plate material can be transported to the dry film cutting structure 330 through the flexible plate buffer mechanism 302, and the dry film cutting structure 330 can cut off the dry film outside the edge of each flexible plate on the continuous flexible plate material, and the flexible plate after cutting the dry film (i.e., the film-coated flexible plate product) can be transferred to the discharge conveying structure 320; the single film-coated flexible plate product can be transported to the bottom of the discharge and material collection structure 340 through the discharge and material collection structure 340, and the film-coated flexible plate product on the discharge conveying structure 320 can be grabbed and transferred to the second flexible plate warehouse 350 for storage through the discharge and material collection structure 340.

[0052] Furthermore, the second flexi-plate bin 350 and the discharge conveyor structure 320 can be arranged side by side on the discharge rack 310, with the discharge reclaiming structure 340 positioned horizontally above the second flexi-plate bin 350 and the discharge conveyor structure 320. Similarly, the discharge reclaiming structure 340 can move horizontally between the second flexi-plate bin 350 and the discharge conveyor structure 320, removing the film-laminated flexi-plate products from the discharge conveyor structure 320 and transferring them to the second flexi-plate bin 350. Furthermore, the dry film cutting structure 330 is positioned horizontally on the infeed side of the discharge conveyor structure 320, with the discharge reclaiming structure 340 corresponding to the discharge side of the discharge conveyor structure 320. This results in a compact and rationally designed overall structure for the flexi-plate discharge mechanism 300.

[0053] Furthermore, the discharging and reclaiming structure 340 may include a horizontal reclaiming drive 132 mounted on the discharging frame 310, a lifting drive 134 mounted on the horizontal reclaiming drive 132, and a suction reclaiming and unloading frame 136 mounted on the lifting drive 134. The specific structure of the discharging and reclaiming structure 340 is similar to that of the feeding and reclaiming structure 130 and will not be further described here. Furthermore, the structure of the discharging and reclaiming conveyor structure 320 is similar to that of the feeding and reclaiming conveyor structure 140 and may also be a roller conveyor structure.

[0054] In addition, if Figures 8 and 9As shown, the dry film cutting structure 330 may include a cutting base structure 332 disposed on the discharge rack 310, and a cutting blade structure 334 disposed on the cutting base structure 332. A cutting gap is defined between the cutting base structure 332 and the cutting blade structure 334. As the continuous flexographic material is conveyed from the flexographic buffer mechanism 302 to the discharge conveyor structure 320, it passes through the cutting gap of the dry film cutting structure 330. At this point, the cutting blade structure 334 can remove excess dry film from the edges of each flexographic sheet in the continuous flexographic material to produce a single film-coated flexographic sheet product, which is then transferred to the discharge conveyor structure 320.

[0055] Furthermore, the cutting base structure 332 may include a base rotary drive 3322 mounted on the discharge frame 310, a cutting base frame 3324 connected to the base rotary drive 3322, and a cutting blade structure 334 mounted on the cutting base frame 3324. The base rotary drive 3322 can drive the cutting base frame 3324 and the cutting blade structure 334 thereon to rotate, allowing the cutting blade structure 334 to adjust its cutting angle to accommodate excess dry film extending at different angles from the edges of each flexo sheet on the continuous flexo material, thereby facilitating the removal of excess dry film from the edges of the flexo sheets. Furthermore, the base rotary drive 3322 may include a rotary drive motor mounted on the discharge frame 310 and a rotary transmission structure connected to the rotary drive motor. The cutting base frame 3324 may include a rotary mounting base that rotates a rotary shaft mounted on the rotary mounting base, which connects the rotary transmission structure and the cutting blade structure 334. The rotary drive motor can drive the rotary shaft to rotate, so that the rotary shaft drives the cutting blade structure 334 to rotate, so that the cutting angle of the cutting blade structure 334 corresponds to the dry film at the edge of each flexographic plate on the continuous flexographic plate material.

[0056] Furthermore, the cutting blade structure 334 may include a cutting blade holder 3342 mounted on a rotating shaft of the cutting base frame 3324, a blade lift drive 3344 mounted on the cutting blade holder 3342, and a cutting blade 3346 slidably mounted on the cutting blade holder 3342 and connected to the blade lift drive 3344. A cutting gap is formed between the cutting blade 3346 and the cutting base frame 3324. The blade lift drive 3344 can drive the cutting blade 3346 up and down to cut excess dry film outside the edge of each flexographic plate on the continuous flexographic plate material.

[0057] Furthermore, the discharge rack 310 is provided with a waste storage bin located below the discharge conveyor structure 320, corresponding to the exit side of the cutting gap. Dry film waste remaining outside the edges of each flexo sheet in the continuous flexo sheet material cut by the cutting blade structure 334 falls into the waste storage bin for storage. Furthermore, the dry film cutting structure 330 may include a waste guide plate 336 mounted on the cutting base frame 3324. The waste guide plate 336 is tilted from the discharge side of the cutting gap toward the waste storage bin. Dry film waste cut by the cutting blade structure 334 slides along the downwardly tilted waste guide plate 336 into the waste storage bin.

[0058] The new hot roller laminator 10 provided by the present invention, by providing a flexible plate feeding mechanism 100 and a flexible plate discharging mechanism 300, can achieve automatic feeding and discharging of a single flexible plate. The laminator 200 can automatically output a roll of dry film and heat-press it together with a single flexible plate, so that multiple flexible plates are sequentially pressed onto a continuous dry film to form a continuous flexible plate material. Moreover, during the discharging process, the dry film cutting mechanism 330 provided on the feeding side of the discharging conveying mechanism 320 can automatically cut the excess dry film at the edge of the single flexible plate on the continuous flexible plate material. During the entire dry film laminating and cutting production process, no manual intervention is required, greatly improving production efficiency. The stable product quality is not affected by the operator's quality, and the safety hazards associated with manual dry film cutting are eliminated.
