Abstract
Description
Technical Field
[0001] This invention belongs to the field of laminating machine technology, and specifically relates to a precision laminating machine. Background Technology
[0002] Precision laminating machines are widely used in fields such as electronic component packaging and flexible packaging material lamination. The core requirement is to achieve precise alignment and stable lamination of multiple rolls of film materials to ensure the dimensional accuracy and structural integrity of the final product.
[0003] Existing equipment often relies on manual adjustment of the spacing between guide components to accommodate film materials of different widths. During the adjustment process, there is a lack of a synchronous positioning mechanism for the initial placement of the roll film material, which can easily lead to lateral displacement of the film material during feeding and lamination, causing lamination misalignment. Furthermore, traditional laminating machines are only equipped with a single feeding mechanism. When the roll film material is exhausted, the machine must be stopped to remove the old material, install the new material, and reposition, which is very time-consuming and seriously affects the effective operating efficiency of precision laminating machines. At the same time, the feeding drive for multiple roll film materials often uses independent power sources. The difference in power output can easily lead to inconsistent feeding speeds for each roll of film material, resulting in large fluctuations in film tension. This can easily cause defects such as bubbles and wrinkles during lamination, resulting in a high defect rate. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a precision bonding machine.
[0005] The technical solution adopted to solve the above-mentioned technical problems is: a precision laminating machine, including a processing table and a mounting frame located at one end of the processing table. The top of the processing table is provided with a film laminating mechanism for laminating film materials, and above the film laminating mechanism is a laminating centering mechanism for limiting the width of the film materials. A new and old material welding mechanism is provided at the middle position of the mounting frame near the processing table. Three sets of feeding mechanisms for releasing rolled film materials are provided at one end of the mounting frame, and a film centering mechanism for limiting the initial position of the rolled film materials is provided in the middle of the feeding mechanism. An adjustment mechanism for limiting the rotation of the rolled film materials is provided at the end of the mounting frame near the feeding mechanism. A synchronous drive mechanism for providing power to the three feeding mechanisms is provided at the top of the mounting frame away from the processing table. A control panel is installed at the end of the processing table away from the mounting frame.
[0006] Furthermore, the film bonding mechanism includes a U-shaped frame, three sets of which are evenly installed on the top of the mounting frame, and a hot press roller is provided inside the U-shaped frame. A pair of guide rollers for guiding are provided on one side of the U-shaped frame, and a bonding roller that cooperates with the hot press roller is provided at the bottom of the other side of the U-shaped frame.
[0007] Through the above technical solution, three sets of U-shaped frames provide an installation framework for lamination. After being guided by the guide rollers, the film material enters between the hot press rollers and the lamination rollers. The hot press rollers heat the film material, and the lamination rollers work in conjunction with the hot press rollers to apply pressure to the film material. Through "heating + pressurization", the film material is tightly bonded. The three sets of U-shaped frames correspond to different film materials, and the three sets of film materials correspond to different lamination paths. The first set of film material passes through three sets of hot press rollers + lamination rollers, the second set passes through two sets, and the third set passes through one set, ensuring that the three sets of film materials are laminated sequentially from bottom to top, realizing the sequential lamination of multiple sets of film materials.
[0008] Furthermore, the fitting and centering mechanism includes two sets of bidirectional lead screws, which are symmetrically arranged on both sides above the mounting frame. The outer ends of the two sets of bidirectional lead screws are symmetrically threaded with two sets of limiting frames. The outer ends of the three pairs of guide rollers are symmetrically fitted with sliding sleeves. The two sets of sliding sleeves at the same end of each pair of guide rollers are connected by a fixed rod. The outer sides of the top two rows of sliding sleeves are respectively fixedly connected to the bottom of the two adjacent sets of limiting frames. The bottom of the mounting frame away from the processing table is provided with a first driving device to drive the two sets of bidirectional lead screws to rotate synchronously. The two sets of limiting frames are connected by two sets of connecting components.
[0009] Through the above technical solution, the first driving device drives two sets of bidirectional lead screws to rotate synchronously, so that the outer limiting frame moves closer or further away synchronously along the axis of the bidirectional lead screw. The limiting frame drives the sliding sleeve to move on the guide roller, and adjusts the distance between the sliding sleeves to match the width of the film material, limiting the lateral displacement of the film material. The connecting component enhances the synchronicity of the movement of the two sets of limiting frames. At the same time, one set of limiting frames drives the film material centering mechanism to move, realizing the synchronous adjustment of "fitting width matching" and "initial centering of film material".
[0010] Furthermore, the new and old material welding mechanism includes a horizontal frame plate located at the middle of the end of the mounting frame near the processing table. The horizontal frame plate is positioned above two sets of limiting frames. Three sets of square through slots are evenly distributed on the top of the horizontal frame plate. A fixed seat is installed on one side of the bottom of each square through slot. A movable seat is provided on the other side of the square through slot via a connecting groove and a connecting slider. A pair of clamping guide rollers are symmetrically arranged on the side of the movable seat and the fixed seat that are close to each other. A hot-pressing connection component and an adsorption fixing component are respectively provided on the side of the movable seat near the fixed seat. The bottom of the horizontal frame plate... The component is evenly equipped with three pairs of second electric push rods, and the output end of each pair of second electric push rods is fixedly connected to the two ends of an adjacent set of movable seats. The hot-pressing connection component includes a first electric push rod located in the middle of the movable seat. A connecting plate is installed on the output end of the first electric push rod. Movable rods are symmetrically installed on both ends of the connecting plate near the movable seat. The ends of the two sets of movable rods away from the connecting plate pass through the movable seat and are jointly installed with a soldering head. The soldering head is located between a pair of clamping guide rollers. A pad that cooperates with the soldering head is installed on the side of the fixed seat near the movable seat.
[0011] Through the above technical solution, the old membrane material passes through the clamping guide rollers of the fixed seat, and the head end of the new membrane material is positioned by the adsorption fixing component. The second electric push rod pushes the moving seat closer to the fixed seat. The two sets of clamping guide rollers clamp the joint ends of the new and old membrane materials together to ensure a flat joint. In the hot pressing connection component, the first electric push rod shortens and pushes the welding head towards the pad of the fixed seat through the connecting plate and the movable rod. The welding head is energized and heats up, hot pressing the new and old membrane materials together. After the welding is completed, the second electric push rod drives the moving seat to reset, the first electric push rod extends, and the welding head detaches from the pad, waiting for the next welding.
[0012] Furthermore, the adsorption and fixing component includes a square chamber located on the side of the movable seat near the fixed seat and above the solder head. The square chamber has uniformly distributed suction holes on its outer side. An air extraction cylinder is installed in the middle of the movable seat, and the air inlet end of the air extraction cylinder is connected to the interior of the square chamber. The top end of the piston rod of the air extraction cylinder is fixedly connected to the connecting plate.
[0013] With the above technical solution, when the first electric push rod extends, the connecting plate drives the piston rod of the suction cylinder to move outward, creating negative pressure inside the square chamber. The suction hole adsorbs the head end of the new membrane material, achieving positioning. During welding, the first electric push rod shortens, the piston rod of the suction cylinder resets, the negative pressure inside the square chamber disappears, and the adsorption state is released, without affecting the normal conveying of the membrane material after welding. The square chamber is located above the welding head, ensuring that the head end of the adsorbed new membrane material is precisely aligned with the docking end of the old membrane material.
[0014] Furthermore, the feeding mechanism includes a first rotating tube, which is rotatably connected to the top of one end of the mounting frame via a bearing. A first turntable is mounted on one end of the first rotating tube, and a second turntable with the same center is provided at the end of the first turntable away from the mounting frame. The second turntable and the first turntable are connected by a transmission component. Both the first and second turntables are located above the crossbeam. Two sets of rotating feeding components are provided at the end of the second turntable away from the first turntable. A second driving device for driving the first rotating tube to rotate is provided at the top of the mounting frame away from the first turntable. The transmission component includes slide rods, and there are two pairs of slide rods. The first turntable and the second turntable are fixedly connected by the two pairs of slide rods. A movable seat that can move axially is symmetrically sleeved on the outer side of the two pairs of slide rods. A first tension spring is sleeved on the outer side of the slide rod, and the two ends of the first tension spring are fixedly connected to the movable seat and the second turntable, respectively. A rotatable second rotating tube is provided at the middle position of the movable seat via a bearing. A driven gear is mounted on the outer side of the second rotating tube, and a first rubber ring is mounted on the end of the second rotating tube near the second turntable.
[0015] Through the above technical solution, the roll film material is installed on the loading tray of the loading component. The first turntable and the second turntable are fixedly connected by a slide rod to form a dual-station installation structure (the two loading components are symmetrically distributed). The synchronous drive mechanism drives the driven gear to rotate, which in turn drives the second rotating tube to rotate. The second rotating tube drives the rotating rod of the loading component to rotate through friction transmission between the first rubber ring and the second rubber ring of the loading component, thereby realizing the feeding of the roll film material. When changing materials, the adjustment mechanism pushes the movable seat to move along the slide rod, the first tension spring is stretched, the first rubber ring and the second rubber ring are separated, the loading component to be changed stops rotating, the second drive device drives the first rotating tube to rotate, so that the turntable rotates 180°, and switches to the standby loading component to continue feeding materials. The first tension spring ensures the dynamic contact between the movable seat and the loading component.
[0016] Furthermore, the loading component includes a rotating rod, which is provided in two sets. Both sets of rotating rods are rotatably connected to the first turntable and the second turntable through two sets of bearings. The end of the rotating rod away from the first turntable passes through the second turntable and is fitted with a loading tray for placing the roll film. A fixing ring is installed on the outside of the rotating rod between the second turntable and the loading tray. A second tension spring is fitted on the outside of the rotating rod and fixedly connected to the loading tray and the fixing ring. A second rubber ring that cooperates with the first rubber ring is installed on the outside of the rotating rod. The second rotating tube is fitted on the outside of the rotating rod.
[0017] With the above technical solution, the roll film is sleeved on the outside of the loading tray. One end of the second tension spring is connected to the loading tray, and the other end is connected to the fixing ring (fixed on the rotating rod). Through the elastic extension and contraction of the tension spring and the film centering mechanism, the loading tray can accommodate roll film of different widths, and the roll film is always located above the center of the processing table. The rotating rod is rotatably connected to the turntable through the bearing. The second rubber ring on its outer side is in frictional contact with the first rubber ring of the second rotating tube. After receiving power, it drives the loading tray to rotate, thereby releasing the film. The second rotating tube is sleeved on the outside of the rotating rod to ensure coaxiality during transmission and avoid material deviation caused by eccentricity.
[0018] Furthermore, the synchronous drive mechanism includes a third rotating tube fitted inside the first rotating tube. A worm gear is installed at one end of the outer side of the third rotating tube, and a wide gear that meshes with two sets of driven gears is installed at the other end of the outer side of the third rotating tube. Three sets of worms are evenly arranged on the top of the mounting frame away from the processing table, and the three sets of worms mesh with an adjacent set of worm gears. The three sets of worms are connected by a connecting shaft. A servo motor that drives the three sets of worms to rotate is installed on one side of one end of the mounting frame.
[0019] Through the above technical solution, the servo motor drives the connecting shaft to rotate, and the connecting shaft synchronously drives the three sets of worm gears to rotate. The worm gears mesh with the worm wheels, which drive the third rotating tube, which is inner sleeved in the first rotating tube, to rotate, thereby achieving speed reduction and torque increase, and ensuring stable material feeding power. The wide gear on the outside of the third rotating tube meshes with the driven gear of the feeding mechanism. Since the three sets of worm gears and worm wheels have the same specifications, the three sets of third rotating tubes have the same rotation speed, which ultimately drives the three sets of feeding mechanisms to feed materials synchronously.
[0020] Furthermore, the adjustment mechanism includes three sets of electric telescopic rods, which are evenly installed on the top of the mounting frame near the processing table. The output end of the electric telescopic rod is equipped with a mounting plate, and the mounting plate is equipped with a guide wheel near the movable seat. A pair of movable seats are symmetrically provided with arc-shaped grooves that cooperate with the guide wheels at the center of the edge position near the second turntable. The depth of the arc-shaped groove gradually decreases from one end to the other end, and the shallowest end of the arc-shaped groove is located at the middle position of the edge of the movable seat.
[0021] With the above technical solution, during material change, the electric telescopic rod shortens, driving the guide wheel on the mounting plate to move towards the movable seat. The guide wheel is embedded in the arc-shaped groove on the edge of the movable seat (the groove depth gradually decreases from one end to the other). As the telescopic rod shortens, the guide wheel rolls along the arc-shaped groove and pushes the movable seat to move along the slide bar. The first tension spring is stretched, the first rubber ring separates from the second rubber ring, and the material feeding mechanism stops. After the material change is completed, the electric telescopic rod extends, the guide wheel rolls in the opposite direction along the arc-shaped groove, the tension of the first tension spring drives the movable seat to reset, the rubber rings re-fit, the transmission is restored, and the material feeding mechanism continues to work. The gradually changing depth design of the arc-shaped groove enables the guide wheel to push the movable seat to move, thereby controlling whether the first rubber ring and the second rubber ring engage in frictional transmission.
[0022] Furthermore, the membrane centering mechanism includes a push rod fitted inside the third rotating tube. One end of the push rod passes through the center of the second turntable and is mounted on a disc. A ring of balls is evenly arranged at the edge of the disc away from the push rod. A crossbar is mounted on the ends of the three sets of push rods away from the disc. Vertical rods are mounted on both sides of the bottom of the crossbar. A sliding longitudinal rod is mounted on the bottom end of the vertical rod. The ends of the two sets of sliding longitudinal rods away from the vertical rods pass through the mounting frame and are fixedly connected to the outer side of the adjacent set of limiting frames.
[0023] With the above technical solution, when the limiting frame of the bonding and centering mechanism moves, it drives the sliding longitudinal rod to slide along the mounting frame. The sliding longitudinal rod drives the horizontal rod to move through the vertical rod, which in turn pushes the push rod, which is fitted inside the third rotating tube, to move axially. The push rod drives the disc to move closer to the loading tray. The ball bearings on the edge of the disc contact the outer ring of the loading tray. Since the three sets of push rods move synchronously, the three sets of discs position the loading tray from different directions, ultimately aligning the axis of the rolled film with the centering axis of the processing table and the bonding mechanism. The rolling contact between the ball bearings and the loading tray replaces the sliding contact, reducing the frictional resistance when the loading tray rotates.
[0024] The beneficial effects of the present invention are as follows: (1) The present invention uses the bonding centering mechanism and the film centering mechanism to drive two sets of bidirectional screws to rotate synchronously, so that the limiting frame drives the sliding sleeve to move along the guide roller to adapt to the width of the film. At the same time, one set of limiting frames drives the disc to approach the loading plate through the sliding longitudinal rod, upright rod and cross rod transmission, and uses the ball bearings on the edge of the disc to position the rolled film in the circumference, ensuring that it is aligned with the center axis of the bonding roller and the hot pressing roller; (2) The present invention is equipped with two sets of symmetrical loading components through the feeding mechanism. When changing materials, the adjustment mechanism can quickly separate the power, control the electric telescopic rod to shorten, and the guide wheel rolls along the arc groove to push the movable seat. Move to separate the two sets of rubber rings. The material loading component to be replaced stops rotating. The spare component can be loaded with new material in advance. After the old and new film materials are connected by the welding mechanism, the turntable can be rotated 180° to switch to new material. No machine stop is required throughout the process, and the equipment operating efficiency is effectively improved. (3) The synchronous drive mechanism of the present invention adopts a single power source design. The servo motor drives the three sets of worm gears to rotate synchronously through the connecting shaft. The worm wheel drives the third rotating tube to rotate. Its outer wide gear meshes with the driven gear, and synchronously drives the second rotating tube of the three feeding mechanisms to rotate. Finally, the three feeding components are fed synchronously, which effectively reduces the bubbles or wrinkles generated during the film bonding process. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0028] like Figures 1-6As shown, a precision laminating machine according to this embodiment includes a processing table 1 and a mounting frame 2 located at one end of the processing table 1. A film laminating mechanism 3 for laminating film materials is provided on the top of the processing table 1, and a laminating centering mechanism 4 for limiting the width of the film material is provided above the film laminating mechanism 3. A control panel 10 is installed at the end of the processing table 1 away from the mounting frame 2. The film laminating mechanism 3 includes a U-shaped frame 301, with three sets of U-shaped frames 301 evenly installed on the top of the mounting frame 2. A hot press roller 302 is provided inside the U-shaped frame 301, and a pair of guide rollers 303 for guiding are provided on one side of the inside of the U-shaped frame 301. On the other side of the bottom, a bonding roller 304 is provided to cooperate with the hot press roller 302. The bonding centering mechanism 4 includes a bidirectional lead screw 401. Two sets of bidirectional lead screws 401 are provided, and the two sets of bidirectional lead screws 401 are symmetrically arranged on both sides above the mounting frame 2. Two sets of limiting frames 402 are symmetrically threaded at both ends of the outer sides of the two sets of bidirectional lead screws 401. Sliding sleeves 403 are symmetrically sleeved at both ends of the outer sides of the three pairs of guide rollers 303. The two sets of sliding sleeves 403 at the same end of each pair of guide rollers 303 are connected by a fixing rod. The outer sides of the top two rows of sliding sleeves 403 are fixedly connected to the bottom of the two adjacent sets of limiting frames 402 respectively. 2. At the bottom of the part away from the processing table 1, a first driving device 404 is provided to drive two sets of bidirectional lead screws 401 to rotate synchronously. Two sets of connecting parts 405 are provided between the two sets of limiting frames 402. The first driving device 404 is controlled by the control panel 10 to drive the two sets of symmetrical bidirectional lead screws 401 to rotate synchronously in the forward direction (because the threads at both ends of the bidirectional lead screws are reversed, the two sets of limiting frames 402 move closer to each other synchronously along the lead screw axis). The limiting frames drive the sliding sleeves 403 to slide on the guide rollers 303 through the fixed rods until the distance between the two sets of sliding sleeves is completely matched with the width of the film material to be processed, forming a limit on both sides of the film material to prevent conveying deviation. At the same time, the two sets of limiting frames are connected by The connecting component 405 maintains synchronous movement and ensures centering accuracy. After the direction of the roll film material is corrected by the guide roller 303, it is fed into the U-shaped frame 301. The three sets of U-shaped frames correspond to the three sets of film materials in a layered bonding path. The first set of film materials passes between the hot pressure rollers 302 and the bonding rollers 304 of the three sets of U-shaped frames in sequence. The second set passes through two sets, and the third set passes through one set. The hot pressure rollers provide hot pressure, and the bonding rollers provide support, so that the three sets of film materials are tightly bonded from bottom to top. The layered bonding path design, combined with the "hot pressure + physical bonding" of the hot pressure rollers and the bonding rollers, reduces the problem of uneven pressure when bonding multiple layers of film materials at the same time, reduces the interlayer bubble rate, and ensures a firm bond.
[0029] like Figures 7-10As shown, in this embodiment, a new and old material welding mechanism 5 is provided at the middle position of the mounting frame 2 near the processing table 1. The new and old material welding mechanism 5 includes a horizontal frame plate 501 located at the middle position of the mounting frame 2 near the processing table 1. The horizontal frame plate 501 is located above two sets of limiting frames 402. Three sets of square through slots 502 are evenly opened on the top of the horizontal frame plate 501. A fixed seat 503 is installed on one side of the bottom of the square through slot 502. A movable moving seat 504 is provided on the other side of the square through slot 502 through a connecting slide and a connecting slider. A pair of clamping guide rollers 505 are symmetrically arranged on the side of the moving seat 504 and the fixed seat 503 that are close to each other. A hot pressing connection component 506 and a suction device are respectively provided on the side of the moving seat 504 near the fixed seat 503. The mounting component 507 includes three pairs of second electric push rods 508 evenly installed on the bottom of the crossbeam 501. The output end of each pair of second electric push rods 508 is fixedly connected to both ends of an adjacent set of movable seats 504. The hot-pressing connection component 506 includes a first electric push rod 5061 located in the middle of the movable seat 504. A connecting plate 5062 is installed on the output end of the first electric push rod 5061. Movable rods 5063 are symmetrically installed on both ends of the connecting plate 5062 near the movable seat 504. The ends of the two sets of movable rods 5063 away from the connecting plate 5062 pass through the movable seat 504 and are jointly mounted with a solder head 5064. The solder head 5064 is located between a pair of clamping guide rollers 505. The mounting base 503 is located on the side near the movable seat 504. A pad 5065 is installed to cooperate with the solder head 5064. The adsorption and fixing component 507 includes a square chamber 5071, which is located on the side of the movable seat 504 near the fixed seat 503 and above the solder head 5064. Suction holes 5072 are evenly distributed on the outer side of the square chamber 5071. An air extraction cylinder 5073 is installed in the middle of the movable seat 504, and the air inlet of the air extraction cylinder 5073 communicates with the interior of the square chamber 5071. The top of the piston rod of the air extraction cylinder 5073 is fixedly connected to the connecting plate 5062. When the old film material is about to run out, the head end of the new film material is attached to the outside of the square chamber 5071, and the first electric push rod 5061 is extended, pushing the connecting plate 5062 to drive the air extraction cylinder 5071. The piston rod of 073 moves outward, creating negative pressure inside the square chamber. This pressure firmly adheres the new membrane material head end through the suction hole 5072, achieving precise positioning. The control panel 10 controls the second electric push rod 508, whose output pushes the moving seat 504 along the sliding groove of the square through slot 502 towards the fixed seat 503 until the two sets of clamping guide rollers 505 clamp the old membrane material (fixed seat 503 side) and the new membrane material (moving seat 504 side) respectively, ensuring that the joint ends of the old and new membrane materials are flat and aligned. Then, the first electric push rod is controlled to quickly shorten, and the connecting plate pushes the solder head 5064 towards the pad 5065 of the fixed seat through the movable rod 5063. The solder head 5064 is energized and heats up, hot-pressing the joint ends of the old and new membrane materials together. At the same time, the suction cylinder piston resets.After the negative pressure in the square chamber is released and welding is completed, the second electric push rod drives the moving seat to reset, ready for the next docking.
[0030] like Figure 4 and Figures 11-19As shown, in this embodiment, one end of the mounting frame 2 is provided with three sets of feeding mechanisms 6 for releasing the rolled film. The middle part of the feeding mechanism 6 in this embodiment is provided with a film centering mechanism 9 to limit the initial position of the rolled film. The feeding mechanism 6 includes a first rotating tube 601, which is rotatably connected to the top of one end of the mounting frame 2 via a bearing. One end of the first rotating tube 601 is equipped with a first turntable 602. The end of the first turntable 602 away from the mounting frame 2 is provided with a second turntable 603 whose center coincides with the first turntable 603. The second turntable 603 and the first turntable 602 are connected by a transmission component 604. Both the first turntable 602 and the second turntable 603 are located above the crossbeam 501, with the second turntable 603 being away from the first turntable. Two sets of rotating feeding components 605 are provided at one end of the 602. A second driving device 606 for driving the first rotating tube 601 to rotate is provided at the top of the mounting frame 2 away from the first turntable 602. The transmission component 604 includes slide rods 6041, and there are two pairs of slide rods 6041. The first turntable 602 and the second turntable 603 are fixedly connected by the two pairs of slide rods 6041. The outer sides of the two pairs of slide rods 6041 are symmetrically fitted with movable seats 6042 that can move axially. The outer sides of the slide rods 6041 are fitted with first tension springs 6043, and the two ends of the first tension springs 6043 are fixedly connected to the movable seats 6042 and the second turntable 603 respectively. A rotatable second rotating tube 60 is provided at the middle position of the movable seat 6042 through a bearing. 44. A driven gear 6045 is installed on the outer side of the second rotating tube 6044. A first rubber ring 6046 is installed on the end of the second rotating tube 6044 near the second turntable 603. The loading component 605 includes a rotating rod 6051. Two sets of rotating rods 6051 are provided, and both sets of rotating rods 6051 are rotatably connected to the first turntable 602 and the second turntable 603 through two sets of bearings. The end of the rotating rod 6051 away from the first turntable 602 passes through the second turntable 603 and is fitted with a loading tray 6052 for placing the roll film. A fixing ring 6054 is installed on the outer side of the rotating rod 6051 between the second turntable 603 and the loading tray 6052. A fixing ring 6054 is fitted on the outer side of the rotating rod 6051 to connect with the loading tray 6052 and the fixing ring 6052. A second tension spring 6053 is fixedly connected to the ring 6054. A second rubber ring 6055 that cooperates with the first rubber ring 6046 is installed on the outside of the rotating rod 6051. A second rotating tube 6044 is sleeved on the outside of the rotating rod 6051. The membrane material centering mechanism 9 includes a push rod 904 that is sleeved inside the third rotating tube 704. One end of the push rod 904 passes through the center of the second turntable 603 and is mounted on a disc 905. A ring of balls 906 is evenly arranged on the edge of the disc 905 away from the push rod 904. A crossbar 903 is installed on the end of the three sets of push rods 904 away from the disc 905. Vertical rods 902 are installed on both sides of the bottom of the crossbar 903. A sliding vertical rod 901 is installed at the bottom end of the vertical rod 902.Furthermore, the ends of the two sets of sliding longitudinal rods 901 away from the upright rod 902 pass through the mounting bracket 2 and are fixedly connected to the outer side of the adjacent set of limiting brackets 402. The roll film is fitted onto the outer side of the loading tray 6052 of the loading component 605. The second tension spring 6053 (connecting the loading tray 6052 and the fixing ring 6054) adapts to roll film of different widths through elastic extension and contraction, ensuring that the film is installed stably. When the limiting bracket 402 moves, it synchronously drives the sliding longitudinal rod 901 to slide along the mounting bracket 2. The sliding longitudinal rod 901 drives the horizontal rod 903 through the upright rod 902, pushing the push rod 904, which is inner sleeved in the third rotating tube 704, to move axially. The push rod 904 drives the circular... The disc 905 approaches the loading disc, and the ball bearings 906 on the edge of the disc contact the outer ring of the loading disc. The three discs are positioned synchronously, aligning the axis of the rolled film with the central axis of the processing table and bonding mechanism, completing the initial centering. Then, the second rotating tube 6044 is driven to rotate. The second rotating tube 6044, through friction transmission between the first rubber ring 6046 and the second rubber ring 6055, drives the rotating rod 6051 and the loading disc 6052 to rotate, achieving stable release of the rolled film. During material change, the second driving device 606 drives the first rotating tube 601, the first turntable 602, and the second turntable 603 to rotate 180° clockwise, switching to the spare loading disc 6052 to continue feeding.
[0031] like Figure 16 and Figures 18-19As shown, in this embodiment, the mounting frame 2 is provided with an adjustment mechanism 8 for restricting the rotation of the roll film at one end near the feeding mechanism 6. The adjustment mechanism 8 includes an electric telescopic rod 801, and three sets of electric telescopic rods 801 are provided. The three sets of electric telescopic rods 801 are evenly installed on the top of the mounting frame 2 near the processing table 1. An installation plate 802 is installed on the output end of the electric telescopic rod 801. A guide wheel 803 is installed on the end of the installation plate 802 near the movable seat 6042. A pair of movable seats 6042 are symmetrically provided with arc-shaped grooves 804 that cooperate with the guide wheels 803 at the edge position near the second turntable 603. The depth of the arc-shaped grooves 804 gradually decreases from one end to the other end. The shallowest end of the arc-shaped grooves 804 is located at the middle position of the edge of the movable seat 6042. When it is necessary to replace a certain set of roll film, the electric telescopic rod 801 is shortened by controlling the control panel 10. Its output end drives the guide wheel 803 on the installation plate 802 to move towards the movable seat 6042. 042 moves, the guide wheel embeds into the arc-shaped groove 804 on the edge of the movable seat (the groove depth gradually decreases from one end to the other). As the electric telescopic rod 801 shortens, the guide wheel 803 rolls along the arc-shaped groove 804 and pushes the movable seat 6042 to move away from the second turntable 603 along the slide rod 6041. The first tension spring 6043 is stretched under force. Finally, the first rubber ring 6046 on the movable seat 6042 separates from the second rubber ring 6055, the transmission is interrupted, and the loading tray 6052... After the welding head 5064 and the pad 5065 have finished welding the old and new sets of membranes, the second electric push rod 508 shortens while the electric telescopic rod 801 extends, so that the loading tray 6052 containing the new set of roll membrane material can also rotate synchronously and release the membrane material. This avoids the old roll membrane material from pulling the new roll membrane material during the release process, which would cause the weld joint between the old and new membrane materials to fail due to increased force, thus ensuring a seamless connection during the replacement of the old and new membrane materials.
[0032] like Figures 1-3 and Figures 13-16As shown, in this embodiment, a synchronous drive mechanism 7 is provided on the top of the mounting frame 2 at the end away from the processing table 1 to provide power for the three sets of feeding mechanisms 6. The synchronous drive mechanism 7 includes a third rotating tube 704 fitted inside the first rotating tube 601. A worm gear 706 is installed at one end of the outer side of the third rotating tube 704, and a wide gear 705 that meshes with two sets of driven gears 6045 is installed at the other end of the outer side of the third rotating tube 704. Three sets of worm gears 701 are evenly arranged on the top of the mounting frame 2 at the end away from the processing table 1, and the three sets of worm gears 701 mesh with an adjacent set of worm gears 706. The three sets of worm gears 701 are connected by a connecting shaft 702. A servo drive that drives the three sets of worm gears 701 to rotate is installed on one side of one end of the mounting frame 2. The servo motor 703 is started via the control panel. Its output drives the connecting shaft 702 to rotate. The connecting shaft is fixedly connected to three sets of worm gears 701, synchronously driving the three sets of worm gears 701 to rotate. Each set of worm gears 701 meshes with the corresponding worm wheel 706 to achieve speed reduction and torque increase, driving the third rotating tube 704, which is sleeved inside the first rotating tube 601, to rotate. The wide gear 705 on the outside of the third rotating tube meshes with the driven gear 6045, driving the second rotating tube 6044 to rotate. Finally, the material is discharged from the loading tray 6052 through the friction transmission of the rubber ring. The worm gear transmission has a self-locking characteristic. When the servo motor stops or the film material stops being conveyed, the worm wheel cannot drive the worm gear in reverse, preventing the rolled film material from rolling back due to its own weight and ensuring the stability of the discharge position.
[0033] like Figure 4 and Figure 6 As shown, the first driving device 404 in this embodiment includes a synchronous pulley, a synchronous belt, and a first driving motor. The same end of the outer side of the two sets of bidirectional lead screws 401 passes through the mounting frame 2 and is equipped with a synchronous pulley. The two sets of synchronous pulleys are equipped with a synchronous belt for transmission. The bottom of one side of the mounting frame 2 is equipped with a first driving motor that is connected to the adjacent set of bidirectional lead screws 401. The first driving motor is controlled to drive the bidirectional lead screw 401 connected to it to rotate. The bidirectional lead screw 401 drives the other set of bidirectional lead screws to rotate synchronously through the meshing transmission of the synchronous pulley and the synchronous belt, ensuring that the speed and direction of the two sets of bidirectional lead screws are completely consistent, thereby realizing the synchronous movement of the two sets of limit frames 402.
[0034] like Figures 11-15As shown, the second driving device 606 in this embodiment includes a driving gear, a driven gear, and a second driving motor. A driven gear is installed on the outer side of the first rotating tube 601 away from the first turntable 602. A second driving motor is installed on the top of one end of the mounting bracket 2, and a driving gear that meshes with the driven gear is installed on the output end of the second driving motor. When the film material of a material loading tray 6052 is used up and welding is completed, the second driving motor is controlled to drive the driving gear to rotate. The driving gear meshes with the driven gear, thereby driving the first rotating tube 601 to rotate. The first rotating tube 601 is fixedly connected to the first turntable 602. The first turntable 602 is fixedly connected to the second turntable 603 through a slide rod 6041, thereby driving the two material loading components 605 to rotate 180° clockwise, switching the spare material loading tray 6052 to the working position and the empty material loading tray 6052 to the waiting material loading position.
[0035] like Figures 1-4 As shown, the top of the processing table 1 in this embodiment is provided with two pairs of figure-eight shaped lower pressure rollers, and a pair of upper pressure rollers that cooperate with the lower pressure rollers are provided between two adjacent sets of U-shaped frames 301. Both the upper and lower pressure rollers are located below the two sets of limiting frames 402. The multilayer film material, which has been initially bonded by the hot pressing roller 302 and the bonding roller 304, enters between the figure-eight shaped lower pressure roller and the upper pressure roller in the conveying direction. Since the lower pressure roller is figure-eight shaped, the pressure force on the film material gradually increases during the conveying process. Combined with the downward pressure of the upper pressure roller, the air bubbles remaining between the film material layers are squeezed out, and the film material is further compacted.
[0036] like Figure 6 As shown, the connecting component 405 in this embodiment includes a limiting slide groove 4051. Two sets of limiting slide grooves 4051 are provided, and the two sets of limiting slide grooves 4051 are symmetrically opened at the ends of the two sets of limiting frames 402 that are close to each other. A limiting slider 4052 is provided inside the limiting slide groove 4051. Connecting rods 4054 are symmetrically hinged to the outer sides of the two sets of limiting sliders 4052, and the two sets of connecting rods 4054 are distributed in a crisscross pattern. The two sets of connecting rods 4054 are connected at their middle positions by a hinge shaft 4053. The end of the slider away from the limit slider 4052 is hinged to the adjacent set of limit frames 402. When the bidirectional lead screw 401 drives the two sets of limit frames 402 to move closer or further away, the cross link rotates around the connecting shaft and the slider slides along the slide groove. Due to the symmetrical structure of the cross link, the moving distance and speed of the two sets of limit frames 402 are completely consistent, avoiding the sliding sleeve from shifting due to excessive movement on one side. The "X" shaped cross structure can disperse the force on the limit frame 402, avoiding deformation of the limit frame 402 due to excessive force on one side, and extending its service life.
[0037] The working principle of this embodiment is as follows: Three sets of roll film are respectively installed on the outside of the loading tray 6052. Then, the first driving device 404 is controlled to drive the two sets of bidirectional lead screws 401 to rotate synchronously in the forward direction. The two sets of limiting frames 402 on the outside of the bidirectional lead screws 401 move synchronously along the axial direction of the bidirectional lead screws 401. The two sets of limiting frames 402 drive the two sets of sliding sleeves 403 to move synchronously on the guide rollers 303 until the distance between the two sets of sliding sleeves 403 matches the width of the film. At the same time, one set of limiting frames 402 drives the two sets of sliding longitudinal rods 901 to move. The sliding longitudinal rods 901 are driven by the vertical rods 902 and the horizontal rods 903 to push the push rod 904 to drive the disc 905 to move closer to the loading tray 6052. The ball bearings 90 on the edge of the disc 905 move towards the loading tray 6052. 6. Contacting the outer ring of the loading tray 6052, the film rolls on the loading tray 6052 are positioned at the exact center above the processing table 1 (above the exact center of the hot press roller 302 or guide roller 303) through the synchronous positioning of the three sets of discs 905, completing the initial centering. Then, the heads of the three sets of film rolls are guided by the guide roller 303 and pass between the hot press roller 302 and the bonding roller 304. At this time, the head of the first set of film rolls passes between the three sets of hot press rollers 302 and the bonding roller 304, the head of the second set of film rolls passes between the two sets of hot press rollers 302 and the bonding roller 304, and the head of the third set of film rolls passes between only one set of hot press rollers 302 and the bonding roller 304, so that the three sets of film rolls are bonded to each other in sequence. The servo motor 703 drives three sets of worm gears 701 to rotate synchronously via the connecting shaft 702. The worm gears 701 drive the third rotating tube 704 to rotate via the worm wheel 706. The third rotating tube 704 then drives the second rotating tube 6044 to rotate via the wide gear 705 and the driven gear 6045. The first rubber ring 6046 and the second rubber ring 6055 (fixed to the outside of the rotating rod 6051) are driven by friction, which ultimately drives the rotating rod 6051 to rotate, so that the roll of film material rotates with the feeding tray 6052 and is fed. When it is necessary to replace the new material, the electric telescopic rod 801 is shortened, so that the guide wheel 803 rolls along the guide of the arc groove 804, and the guide wheel 803 pushes the movable seat 6042 to move (first tension spring 6043). (Under the force of stretching), the first rubber ring 6046 and the second rubber ring 6055 no longer rub against each other, causing the connected rotating rod 6051 to stop rotating. Meanwhile, the wide gear 705 continues to drive the second rotating tube 6044 to rotate via the driven gear 6045. Then, a new set of roll film is pre-installed on the second assembly tray 6052 (which is stopped and not rotating) outside the second turntable 603. Next, the head end of the new set of roll film is attached to the outside of the square hopper 5071. Immediately afterwards, the first electric push rod 5061 is extended, pushing the connecting plate 5062 to move the piston inside the vacuum cylinder 5073 outwards, evacuating the interior of the square hopper 5071. This causes the head end of the new set of roll film to be adsorbed onto the outside of the square hopper 5071.Then, the second electric push rod 508 is controlled to push the movable seat 504 closer to the fixed seat 503 (this can be actively controlled by the operator or controlled by a laser displacement sensor specifically used to monitor the remaining thickness of the roll film in conjunction with the control panel 10). When the two pairs of clamping guide rollers 505 bring the two sets of film together, the first electric push rod 5061 is controlled to shorten rapidly. The connecting plate 5062 pushes the welding head 5064 to quickly adhere to the pad plate 5065 via the movable rod 5063, performing hot-press welding on the two sets of film. During the process, the air pump 5073 releases the negative pressure in the square chamber 5071, and the electric telescopic rod 801 is controlled to extend. The first tension spring 60... The pulling force of 43 forces the movable seat 6042 to move again towards the second turntable 603, allowing the first rubber ring 6046 and the second rubber ring 6055 to rub and transmit power again. After welding is completed, the second electric push rod 508 is controlled to drive the movable seat 504 away from the fixed seat 503. Then, the second drive device 606 is controlled to drive the first turntable 602 and the second turntable 603 to rotate 180° clockwise, and the electric telescopic rod 801 is controlled to shorten again, so that the loading tray 6052 without roll film material stops rotating after rotating 180°. Then, the next set of roll film material is installed on the loading tray 6052 and the end of the film material is adsorbed and fixed to the outside of the square bin 5071.
