Description

Technical Field

[0001] This invention relates to the technical field of photovoltaic module equipment, specifically a photovoltaic module intelligent laying and cutting machine. Background Technology

[0002] A photovoltaic (PV) module is a composite material consisting of one or two pieces of tempered glass, encapsulating film, and silicon solar cells, laminated at high temperature using a laminator. The cells are connected in series and parallel by wires to the lead-in terminals. It comprises, from top to bottom, a first layer of tempered glass, a second layer of material, a third layer of monocrystalline or polycrystalline solar cells, a fourth layer of material, and a fifth layer of tempered glass or a high-transparency backsheet. Ordinary cutting machines require manual loading and threading of material after a roll is used up. A significant drawback is the need for manual removal of the empty air shaft, a process that requires machine shutdown and operator access to the equipment's operating area—time-consuming, labor-intensive, and posing safety hazards, while also wasting material.

[0003] Document CN 118239322 A discloses photovoltaic module strip film laying equipment and methods, including the following steps: Feeding stage: The material-changing gripper grabs the head of the material roll, pulls out the film strip, and traction it to the tension release station, causing the film strip to lose additional traction; during the material-changing gripper grabbing the head, the time interval between switching each material roll is equal; Traction stage: The film strip is tractioned to the tension release station, and after the first power feeding, the tensioned film strip naturally falls to the expected length; then the naturally falling film strip segment is driven out again by a motor; Application stage: The tension-free film strip output after naturally falling is punched and cut to obtain an application segment of the expected length. The material-picking gripper holds the application segment and transports it to the application position on the photovoltaic panel for pressing and application. The equipment and method disclosed in the document cannot perform rapid, non-stop film changing, affecting the process.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention discloses an intelligent photovoltaic module laying and cutting machine that eliminates the need for manual material loading, material changing, and material removal from empty air shafts. Material changing does not disrupt production line operations, saving labor costs, reducing costs, improving operational safety, and increasing production line efficiency.

[0006] The technical solution of the present invention is as follows: a photovoltaic module intelligent laying and cutting machine, comprising an AGV automatic material replacement device, an intelligent EVA head finding device, an EVA automatic tail-end sequential hot-melt mechanism, and a cutting machine non-stop material storage device. The AGV automatic material replacement device replaces the material rolls. The head of the material roll is clamped by the intelligent EVA head finding device and passed to the EVA automatic tail-end sequential hot-melt mechanism to weld the new head and tail. The cutting machine non-stop material storage device stores and transports the material rolls.

[0007] By adopting the above technical solution, there is no need for manual feeding, material changing, or collection of empty air shafts. Material changing does not affect production line production, saving labor input, reducing costs, improving operational safety, and increasing production line efficiency.

[0008] Preferably, the AGV automatic material transfer device includes an AGV trolley located on one side of the frame and grippers and clamping plates located on the frame. The clamping plates are provided inside the frame, and a transport structure is provided below the clamping plates. Material roll trays are provided between the transport structures. A paper roll storage component is also provided above the transport structure. A transfer gripper structure is provided on one side of the paper roll storage component. The clamping plates are connected to the frame via guide rails.

[0009] By adopting the above technical solution, the material roll pallet is transported to the middle of the space by the AGV trolley, and then the material roll is clamped upward by the clamping plate. When the material roll is unloaded, only the waste paper tube is left. The connecting gripper picks up the waste paper tube between the clamping plates and places it on the paper tube storage component.

[0010] Preferably, the gripper structure includes a rotating structure and a gripper tightening structure. The rotating structure includes a cylinder and a rotating rod fixedly connected to the frame. The cylinder is located on both sides of the rotating rod, and the output end of the cylinder is connected to one end of an L-shaped rotating plate. The end of the rotating plate is fastened to the rotating rod, and the two ends of the rotating rod rotate through bearings and a base. The gripper tightening structure includes grippers and cylinder c. The grippers include a left gripper and a right gripper, which are completely symmetrical. The left and right grippers include L-shaped gripper bodies arranged in opposite directions. The ends of the gripper bodies are provided with inward arcs to facilitate gripping of waste paper tubes. The turning point of the gripper body is connected to the base plate through a rotating shaft. The end of the gripper body is connected to a connecting plate through a rotating shaft a. The end of the connecting plate is rotatably connected inside the base. The base is connected to the output end of cylinder c, and cylinder c is located on the outside of the base plate.

[0011] By adopting the above technical solution, cylinder C controls the tightening and opening of the gripper by pulling the gripper to extend, thereby completing the gripper's gripping and releasing of the waste paper tube. The output end of cylinder C is connected to the base. When cylinder C pulls the base outward, the base drives the connecting plate, which in turn drives the end of the gripper body. The gripper body rotates around the pivot and closes inward, and the gripper body is in a clamped state. When cylinder C pushes the base inward, the base drives the connecting plate, which in turn drives the end of the gripper body. The gripper body rotates around the pivot and opens outward, and the gripper body is in an open state.

[0012] Preferably, the forklift of the AGV trolley places the material roll pallet between the guide rails. The material roll pallet includes a support plate, legs at the bottom of the support plate, and support seats. Support seats are provided on both sides of the upper surface of the support plate. The support seats are provided with downward arc-shaped material roll supports. The spacing between the support seats is less than the length of the material roll. The total height of the legs, the thickness of the support plate, and the height of the support seats is lower than the height of the carrier receiving frame to the bottom.

[0013] Preferably, an intelligent EVA head finding device is provided inside the material roll. The intelligent EVA head finding device includes a displacement device, a clamping device, and a detection structure. The clamping device is located below the material roll, and the displacement device is located above the material roll. The clamping device includes a fixed plate, a moving plate, a receiving plate, and a guide plate. The receiving plate is located inside the fixed plate, and the moving plate is located on one side of the fixed plate. The displacement device includes a guide rail and a base plate connected to the clamping device. A driving structure is provided on the base plate, and the detection structure is located inside the material roll.

[0014] By adopting the above technical solution, when the material roll is unloaded, the displacement device adjusts the clamping device, and then the moving plate leaves the fixed plate, and the material head is located inside the guide plate. Then the material is unloaded until it enters between the moving plate and the fixed plate. After the detection structure detects it, the moving plate closes towards the fixed plate to press the material head, and then the rotary cylinder rotates 90° away from the material roll, so that the material head enters the next process.

[0015] Preferably, the clamping device is located between the clamping plates and below the drive unit connecting the material roll and the clamping plate. The material roll head is fed upward toward the clamping device. The fixed plate has inverted L-shaped support plates at both ends. The inner side of the support plate is connected to the rotating rod a through a rotary cylinder. A fixed plate is fixed on the rotating rod a. The fixed plate has a cylinder aa. The output end of the cylinder aa passes through the fixed plate and connects to the moving plate. The guide plate and the moving plate are in the same plane. The receiving plate is located at the bottom of the fixed plate and between the fixed plate in the same plane. Cylinders bb are provided on both sides of the fixed plate facing the material roll. The output end of the cylinder bb is vertically connected to the receiving plate through the connecting plate a. The side of the connecting plate a is perpendicular to the upper side wall of the receiving plate. The detection structure is located on the fixed plate between the cylinders bb.

[0016] By adopting the above technical solution, the fixed plate can be rotated as a whole to adapt to the next process by means of the rotary cylinder and the rotating rod a. The moving plate 38 is extended by the drive of the cylinder aa39. When the material head passes through, the cylinder aa retracts and the moving plate clamps the material head. After the rotary cylinder rotates 90°, the cylinder bb drives the connecting plate a. The connecting plate a drives the receiving plate away from the fixed plate, so that the end of the receiving plate is closer to the end of the material head. In this way, when the material head and the material tail are welded in the next step, the material head has rigidity and will not sag, which facilitates the welding.

[0017] Preferably, the upper part of the support plate is connected to the displacement device and the EVA automatic tail-end sequential hot-melt mechanism via a base plate. The EVA automatic tail-end sequential hot-melt mechanism is located on the side away from the displacement device of the material roll. The EVA automatic tail-end sequential hot-melt mechanism includes a cutting structure and a welding structure. The cutting mechanism is located between the displacement devices. The cutting structure includes a cutting blade and a pressure plate located at the output end of the rodless cylinder. The welding structure is located on one side of the cutting structure. The welding structure includes a heating block, a welding cylinder, and a heating base plate.

[0018] By adopting the above technical solution, the pre-process intelligent EVA material head finding device automatically extracts the overlapping adhesive film during the connection of new and old adhesive films, realizing the automation of adhesive film welding. The production line does not need to stop and wait, which enhances the continuity and automation of production, improves the efficiency of the production line, shortens the process time, and increases the overall capacity.

[0019] Preferably, the heating base plate is located on the side of the welding base plate, and a baffle is vertically provided on the side of the welding base plate. The upper surface of the baffle is flush with the welding base plate, and there is a gap between the two. The upper part of the cutter is exposed above the gap, and the lower part of the cutter is located on the slider of the rodless cylinder between the baffle and the welding base plate. A pressure plate is provided above the cutter. The bottom of the pressure plate is an inclined surface facing one side. The bottom of the inclined surface has an upward groove that matches the cutter. The top of the pressure plate is driven by the pressure plate cylinder. The heating block is located at the bottom of the mounting plate. The mounting plate is driven by the welding cylinder. The mounting plate has through heat dissipation holes.

[0020] By adopting the above technical solution, when the material roll reaches the tail, if the tail is uneven, it is cut by a cutter. Then, the head of the EVA material is delivered by the preceding intelligent EVA head-finding device, and the head and tail of the material are welded together by the welding structure heating block. The heat dissipation holes on the mounting plate above the heating block are conducive to heat dissipation of the heating block.

[0021] Preferably, a pressure roller is provided on one side of the welding structure, and a material storage device for non-stop material changing of the cutting machine is provided on the outside of the pressure roller. The material storage device for non-stop material changing of the cutting machine includes a storage frame, frame guide rails are installed at the four corners of the storage frame, and tension rollers are respectively provided at the top and bottom between the guide rails. The two sets of tension rollers are rotatably connected at both ends to the rising component connecting plate and the falling component connecting plate, respectively. Slider blocks are slidably installed at both ends of the frame guide rails. The upper slider is installed on the rising component connecting plate through a slider connecting plate, and the lower slider is installed on the falling component connecting plate through the same slider connecting plate. A dual-output shaft motor is provided at the bottom of the falling component connecting plate, and the transmission shaft of the dual-output shaft motor is installed through a coupling.

[0022] Preferably, upper and lower synchronous pulleys are installed on the drive shaft, and upper and lower synchronous pulleys are also installed directly above the upper and lower synchronous pulleys respectively. The upper upper and lower synchronous pulleys are located above the lifting component connecting plate. A synchronous belt is provided between the upper and lower synchronous pulleys. The lifting component connecting plate and the lowering component connecting plate are connected to each other and connected to one side of the synchronous belt respectively.

[0023] By adopting the above technical solution, the power is transmitted to the upper and lower synchronous pulleys on both sides by a dual-output shaft motor driving the transmission shaft. When the upper and lower synchronous pulleys move, they drive the synchronous belt to move. When the synchronous belt moves, it pulls the rising component connecting plate and the falling component connecting plate to move, thereby realizing the up and down movement of the tension roller. A lower synchronous belt connecting plate is set on one side of the synchronous belt and an upper synchronous belt connecting plate is set on the other side of the synchronous belt. This application adopts a form in which a synchronous belt is installed on each side of the frame, and the two synchronous belts are driven by the same dual-output shaft motor 7. The transmission is more precise and the error is smaller. It simplifies the structure of the material storage device and ensures that the upper and lower synchronous pulleys on both sides of the frame maintain the same speed. The rising component connecting plate and the falling component connecting plate on both sides are evenly stressed and will not be skewed. The transmission structure is simple and reliable and has a long service life.

[0024] The advantages of this invention are as follows: 1. The AGV automatic material changing device of this invention, through air, sliders, and guide rails, allows the grippers to extend and retract in any direction within a three-dimensional system. This facilitates the transport of the unloaded waste paper rolls from between the clamping plates to the paper roll collection assembly, completing the processing and collection of the waste paper rolls without the need for manual replacement, effectively improving the efficiency of material changing. By connecting the carrier receiving frame to the inside of the synchronous belt via an L-shaped plate, when the AGV trolley transports the roll to between the guide rails, the roll is placed on the carrier receiving frame. Through the motor and synchronous belt, the roll is automatically transported to the area below the clamping plate for clamping and unloading. This is simple, convenient, and fast, optimizing the overall process, shortening the process time, increasing overall production capacity, facilitating personnel arrangement and allocation, improving the overall production efficiency of the factory area, and increasing profits.

[0025] 2. The intelligent EVA feed head finding device of this invention uses a guide plate set below the feed head. When the feed head droops, the position of the guide plate is moved so that the guide plate is always located outside the feed head, helping the feed head to continue to descend between the moving plate and the fixed plate, which facilitates clamping of the moving plate and the fixed plate. By using a receiving plate, when the feed head is welded to the material position of the next process, the part of the feed head exposed on the receiving plate has rigidity, preventing the feed head from drooping and avoiding overlap between the feed head and the feed tail, thus increasing welding efficiency. The displacement device facilitates the pressing of the feed head by the moving plate and the fixed plate, and after the subsequent rotation is completed, the welding work of the feed head and the feed tail in the next process is completed, improving the overall adaptability of the device, optimizing the feeding and changing process, shortening the process time, increasing the overall production capacity, and facilitating the arrangement and allocation of personnel.

[0026] 3. The EVA automatic tail-end hot-melt mechanism of this invention uses a slotted pressure plate and a cutter to work together, avoiding over-cutting or under-cutting by the cutter. This ensures that the residual edge of the old adhesive film can be removed in one go, reducing cutting defects and improving cutting quality. During the connection of new and old adhesive films, the overlapping adhesive film is automatically extracted, realizing the automation of adhesive film welding. The production line does not need to stop and wait, which enhances the continuity and automation of production, improves the efficiency of the production line, shortens the process time, and increases the overall production capacity.

[0027] 4. The material storage device for the cutting machine that allows for non-stop material changes in this invention employs a single upper and lower synchronous belt installed on each side of the frame. These two synchronous belts are driven by the same dual-output shaft motor, simplifying the structure of the storage device. This design ensures that the upper and lower synchronous pulleys on both sides of the frame maintain the same speed, resulting in even force distribution on the rising and falling connecting plates without skewing. The tension roller moves up and down with the rising and falling connecting plates, which have U-shaped notches, stretching the adhesive film into a serpentine shape, thus providing temporary material storage. This allows for non-stop operation during welding and material changes, optimizing the overall process and shortening the process time. The production line can operate without stopping for each material change, increasing overall capacity and facilitating personnel arrangement and allocation. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] like Figure 1-2 As shown, a photovoltaic module intelligent laying and cutting machine includes an AGV automatic material changing device, an intelligent EVA head finding device, an EVA automatic tail-connecting hot-melt mechanism, and a non-stop material storage device for material changing. The AGV automatic material changing device replaces the material rolls. The head of the roll is clamped by the intelligent EVA head finding device and passed to the EVA automatic tail-connecting hot-melt mechanism to fuse the new head and tail. The non-stop material storage device stores and transports the material rolls. No manual feeding, material changing, or collection of empty air shafts is required. Material changing does not affect production line operation, saving labor costs, reducing costs, improving operational safety, and increasing production line efficiency.

[0032] like Figure 3-6As shown, the AGV automatic material transfer device includes an AGV trolley 8 located on one side of the frame 1 and grippers and clamping plates 7 located on the frame 1. The clamping plates 7 are located inside the frame 1, and a transport structure is located below the clamping plates 7. A material roll tray 9 is located between the transport structures. A paper tube storage assembly 11 is located above the transport structures. A transfer gripper structure is located on one side of the paper tube storage assembly 11. The clamping plates 7 are connected to the frame 1 via guide rails 701. The AGV trolley 8 transports the material roll tray 9 to the middle of the space. Then, the clamping plates 7 clamp the material roll 10 upwards. Material is fed onto the material roll 10. After the material roll 10 is fed, only waste paper tubes 12 are left. The transfer grippers pick up the waste paper tubes 12 between the clamping plates 7 and place them on the paper tube storage assembly 11.

[0033] The gripper structure includes a rotating structure and a gripper tightening structure. The rotating structure includes a cylinder 14 and a rotating rod 13 fixedly connected to the frame 1. The cylinder 14 is located on both sides of the rotating rod 13 and is connected to the frame through a plate. The output end of the cylinder 14 is connected to one end of an L-shaped rotating plate 15. The end of the rotating plate 15 is fastened to the rotating rod 13. The two ends of the rotating rod 13 rotate through bearings and a base. The cylinder 14 drives the L-shaped rotating plate 15. When the cylinder 14 extends or retracts, the L-shaped rotating plate 15 rotates around the rotating rod 13. That is, the L-shaped rotating plate 15 drives the rotating rod 13 to rotate, thereby driving the gripper to rotate. The gripper can be controlled to rotate from between the clamping plates 7 to the paper tube storage assembly 11.

[0034] Each side of the rotating rod 13 is provided with a guide rail a16, and a slider a17 is adapted on the guide rail a16. The slider a17 is driven by a cylinder a18 to slide on the guide rail a16. The side of the slider a17 is connected to a slide plate 19 through a connecting plate 15. A slider b20 is provided at the outer end of the slide plate 19. The slider b20 is adapted to the guide rail b21 on the inner side of the base plate 22. A cylinder b20 is provided between the end of the inner side of the base plate 22 away from the slide plate 19 and the end of the slide plate 19 away from the base plate 22. The cylinder a18 drives the slider a17 to slide on the guide rail a16, which can change the distance between the grippers to facilitate clamping the waste paper tube 12. The cylinder b23 drives the slide plate 19, and the slide plate 19 slides on the guide rail b21 on the base plate 22 through the slider b20, thereby changing the distance between the grippers and the waste paper tube 12, which facilitates gripping the grippers.

[0035] The gripper tightening structure includes grippers and cylinder C24. The grippers include a left gripper and a right gripper, which are completely symmetrical. The left and right grippers include L-shaped gripper bodies 25 arranged in opposite directions. The ends of the gripper bodies 25 are provided with inward arcs to facilitate gripping the waste paper tube 12. The cylinder C24 controls the tightening and opening of the grippers by pulling the grippers to extend, thereby completing the gripping and releasing of the waste paper tube 12 by the grippers.

[0036] The gripper body 25 is connected to the base plate 22 via a pivot 26 at its turning point. The end of the gripper body 25 is connected to the connecting plate 27 via a pivot a. The end of the connecting plate 27 is rotatably connected to the base 28. The base 28 is connected to the output end of the cylinder c24. The cylinder c24 is located outside the base plate 22, and its output end is connected to the base 28. When the cylinder c24 pulls the base 28 outward, the base 28 drives the connecting plate 27, which in turn drives the end of the gripper body 25. The gripper body 25 turns around the pivot 26 and rotates inward to close, resulting in a clamped state. When the cylinder c pushes the base 28 inward, the base 28 drives the connecting plate 27, which in turn drives the end of the gripper body 25. The gripper body 25 turns around the pivot 26 and rotates outward to open, resulting in an open state.

[0037] The paper tube storage assembly 11 is located on the side above the transport structure away from the clamping plate 7. The paper tube storage assembly 11 includes brackets located on both sides of the transport structure. A support platform 1101 is provided inside the bracket. The support platform 1101 is inclined downward towards the side away from the clamping plate 7. A limiting plate 1102 is provided at the end of the support platform 1101 away from the clamping plate 7. The distance between the support platforms 1101 is adapted to the length of the waste paper tube 12. After the material roll 10 is unloaded, the gripper clamps the waste paper tube 12 and places it on the support platform 1101. The limiting plate 1102 can block the waste paper tube 12 to prevent it from falling down.

[0038] The clamping plate 7 clamps the material roll 10 via an air-expanding brake sleeve. The clamping plate 7 slides on the guide rail d31 via a slider d, thereby clamping the material roll 10. The slider d31 is driven by an external cylinder. The guide rail d31 is horizontally positioned on the vertical plate 32. The vertical plate 32 moves up and down on the vertical guide rail e34 via a slider e33, thereby causing the clamping plate 7 to move up and down. The slider e33 is also driven by the cylinder. When the clamping plate 7 needs to clamp the material roll 10, it is opened and placed on both sides of the paper tube of the material roll 10. Then, the clamping plate 7 closes the material roll 10, and the air-expanding brake sleeve is engaged inside the paper tube of the material roll 10. The material roll 10 rotates on the air-expanding brake sleeve to release the material.

[0039] The transport structure includes a motor 2, a synchronous belt 5, and a drive shaft 3. The motor 2 is located between the frames 1. The output shaft of the motor 2 drives the synchronous pulley 4 to drive the synchronous belt 5. The inner side of the synchronous belt 5 is provided with a guide rail 6 parallel to the synchronous belt 5. The guide rail 6 is provided with a suitable carrier receiving frame 602 for supporting the material roll 10. The side of the carrier receiving frame 602 is connected to the synchronous belt 5 through an L-shaped plate 601. When the motor 2 drives the synchronous pulley 4 and thus drives the synchronous belt 5 for transmission, the L-shaped plate 601 will then drive the carrier receiving frame 602 to move on the guide rail 6, thereby transporting the material roll 10 on the carrier receiving frame 602 to the position below the clamping plate 7.

[0040] The forks of the AGV trolley 8 place the material roll 10 pallet between the guide rails 6. The material roll pallet 9 includes a support plate 901, legs 903 at the bottom of the support plate 901, and support seats 902. Support seats 902 are provided on both sides of the upper surface of the support plate 901. The support seats 902 have downward arc-shaped material roll support. The distance between the support seats 902 is less than the length of the material roll 10. The total height of the legs 903, the thickness of the support plate 901, and the height of the support seats 902 is lower than the height of the carrier receiving frame 302 to the bottom. The material roll 10 is placed between the guide rails 6 through the material roll pallet 9 of the AGV trolley 8. Since the carrier receiving frame 602 is higher than the support seats 902, the material roll 10 is placed on the carrier receiving frame 602. Then, it is transported to the area below the clamping plate 7 through the guide rails 6 and the carrier receiving frame 602 for clamping and feeding.

[0041] like Figure 7-11 As shown, the intelligent EVA feed head finding device includes a displacement device, a clamping device, and a detection structure. The clamping device is located below the feed roll 10, and the displacement device is located above the feed roll 10. The clamping device includes a fixed plate 37, a moving plate 38, a receiving plate 40, and a guide plate 3802. The receiving plate 40 is located inside the fixed plate 37, and the moving plate 38 is located on one side of the fixed plate 37. The displacement device includes a guide rail and a base plate 57 connected to the clamping device. A driving structure is provided on the base plate. The detection structure is located inside the feed roll 10. When the feed roll 10 is unloaded, the displacement device adjusts the clamping device, and then the moving plate 38 moves away from the fixed plate 37. The feed head is located inside the guide plate 3802. The feed continues until it enters the space between the moving plate 38 and the fixed plate 37. After being detected by the detection structure, the moving plate 38 closes towards the fixed plate 37 to press the feed head. Then, the rotary cylinder 48 rotates 90° away from the feed roll 10, allowing the feed head to enter the next process.

[0042] The clamping device is located between the clamping plates 7 and below the drive unit connecting the material roll 10 and the clamping plate 7. The material head of the material roll 10 is fed upward toward the clamping device. The fixed plate 37 has inverted L-shaped support plates 50 at both ends. The inner side of the support plate 50 is connected to the rotating rod a49 through the rotating cylinder 48. The fixed plate 37 is fixed on the rotating rod a49. The fixed plate is equipped with a cylinder aa39. The output end of the cylinder aa39 passes through the fixed plate 37 and is connected to the moving plate 38. The fixed plate 37 can be rotated as a whole by the rotating cylinder 48 and the rotating rod a49 to adapt to the next process. The moving plate 38 extends by the drive of the cylinder aa39. When the material head passes through, the cylinder aa39 retracts and the moving plate 38 clamps the material head.

[0043] The bottom of the fixed plate 37 is provided with an upward-facing groove 3701. The groove 3701 does not penetrate the top of the fixed plate 37. The receiving plate 40 is convex upward in shape. The receiving plate 40 fits perfectly into the groove 3701. The two sides of the receiving plate 40 are located inside the fixed plate 37. The receiving plate 40 and the fixed plate 37 are on the same plane. The moving plate 38 is close to the fixed plate 37. The moving plate 38 is driven by the cylinder aa39 on the fixed plate 37 and extends outward. When the whole device rotates, the receiving plate 40 can make the material head spread flat on the receiving plate 40 for the next step and the material position to be welded, so that the material head does not face downward.

[0044] The inner surface of the moving plate 38 is provided with an inward rectangular groove 3801. The guide plate 3802 is located in the rectangular groove 3801. The rectangular groove 3801 does not penetrate the bottom and outer side of the moving plate 38. The guide plate 3802 is located in the rectangular groove 3801 and is in the same plane as the moving plate 38. The part of the guide plate 3802 located outside the moving plate 38 is inclined outward. When the material roll 10 is unloaded, the material roll 10 is located inside the guide plate 3802. When the material head is unloaded, the guide plate 3802 can guide the material head, so that the material head is unloaded between the moving plate 38 and the fixed plate 37 under the action of the guide plate 3802. The guide plate 3802 can prevent the material head from being unloaded outward and accurately enter the position between the moving plate 38 and the fixed plate 37.

[0045] On one side of the fixed plate 37 facing the material coil 10, there are cylinders bb41. The output end of the cylinder bb41 is vertically connected to the receiving plate 40 through the connecting plate a42. The side of the connecting plate a42 is perpendicular to the upper side wall of the receiving plate 40. When the rotating cylinder 48 rotates 90°, the cylinder bb41 drives the connecting plate a, and the connecting plate a42 moves the receiving plate 40 away from the fixed plate 37, so that the end of the receiving plate 40 is closer to the end of the material head. In this way, when the material head and the material tail are welded in the next step, the material head has rigidity and will not sag, which facilitates the welding.

[0046] The detection structure is located on the fixed plate 37 between cylinders bb41. The detection structure includes cylinder cc43, the output end of which is rotatably connected to one end of T-shaped plate 44. The other end of T-shaped plate 44 is connected to detection bracket 45. Photoelectric sensor 47 is installed inside detection bracket 45. The bottom of T-shaped plate 44 is connected to the side wall of fixed plate 37 via rotating shaft a46. Photoelectric sensor 47 rotates counterclockwise around rotating shaft a46. Photoelectric sensor 47 is located at the lower edge of receiving plate 40. The transmitting end of photoelectric sensor 47 has a corresponding receiving end located outside the material head. When the signal of photoelectric sensor 47 is blocked by the material head, it indicates that the material head... The material head has exceeded the length of the receiving plate 40. The photoelectric sensor 47 can be placed at a position corresponding to the distance from the receiving plate 40 according to actual needs. The photoelectric sensor 47 and all cylinders and motors a in the device are connected to an external controller, which is a conventional method in the art. When the receiving end does not receive the signal from the photoelectric sensor 47, the controller controls the clamping plate 7 to stop feeding. The method of the clamping plate 7 feeding the material roll 10 is a conventional method in the art. The material roll 10 stops feeding and controls the cylinder aa39 to retract the moving plate 38, so that the moving plate 38 and the fixed plate 37 clamp the material head.

[0047] The top of the support plate 6 is provided with a vertically upward guide rail aa51. A base a53 is provided on one side of the guide rail aa51 via a slider aa52. The output end of the cylinder d18 is connected to the base a53. The cylinder d18 is connected to the frame. The base a53 is fixed by the connecting plate 55 and the connecting block 56. The cylinder d54 drives the base a53, which can make the clamping device move up and down as a whole to adapt to the clamping work of the moving plate 38 and the fixed plate 37 on the material head, and the subsequent welding work of the material head and the material tail.

[0048] The connecting block 56 is connected to the guide rail bb36 via the slider bb58. The guide rail bb36 is located on the base plate 57, which is connected to the frame. The base plate 57 is perpendicular to the guide rail aa51 in space. One end of the base plate 57 is equipped with a motor a59. The output end of the motor a59 is connected to the bearing at the end of the connecting block 56 and the base plate 57 via the lead screw 35. The connecting block 56 and the lead screw 27 are adapted to each other. The bottom of the connecting block 56 is fixedly connected to the slider bb58. The motor a59 drives the lead screw 35 to move the connecting block 56. The connecting block 56 drives the slider bb58 to move laterally on the guide rail bb36. This can be adapted to the clamping work of the moving plate 38 and the fixed plate 37 on the material head, and the subsequent welding work of the material head and tail.

[0049] The upper part of the support plate 50 is connected to the displacement device and the EVA automatic tail-end sequential hot-melt mechanism via the base plate 57. The EVA automatic tail-end sequential hot-melt mechanism is located on the side away from the displacement device. The EVA automatic tail-end sequential hot-melt mechanism includes a cutting structure and a welding structure. The cutting mechanism is located between the displacement devices. The cutting structure includes a cutter 60 and a pressure plate 64 located at the output end of the rodless cylinder 61. The welding structure is located on one side of the cutting structure. The welding structure includes a heating block 69, a welding cylinder 67 and a heating base plate 70. The intelligent EVA head-finding device automatically extracts the overlapping film during the connection of new and old adhesive films, realizing the automation of adhesive film welding. The production line does not need to stop and wait, which enhances the continuity and automation of production, improves the efficiency of the production line, shortens the process time, and increases the overall capacity.

[0050] A heating base plate 70 is located on the side of a welding base plate 71. A baffle 62 is vertically installed on the side of the welding base plate 71. The upper surface of the baffle 62 is flush with the welding base plate 71, and there is a gap between them. The upper part of the cutter 60 protrudes above the gap, and the lower part of the cutter 60 is located on the slider of the rodless cylinder 61 between the baffle 62 and the welding base plate 71. A pressure plate 64 is installed above the cutter 60. The bottom of the pressure plate 64 is inclined to one side, and the bottom of the inclined surface has an upward groove 65 that matches the cutter 60. This avoids over-cutting or under-cutting by the cutter, ensuring that the residual edge of the old adhesive film can be removed in one go, reducing cutting defects and improving cutting quality. The top of the pressure plate 64 is driven by a pressure plate cylinder 66. A heating block 69 is located at the bottom of a mounting plate 68. 68 is driven by welding cylinder 67, which is fixedly connected to welding cylinder bracket 63 and pressure plate 64. The mounting plate 68 is provided with through heat dissipation holes. When the material roll 10 reaches the end, if the end is uneven, it is cut by cutter 60. Then, the material head is delivered by the intelligent EVA material head finding device in the previous step. The material head and the material tail are welded by the welding structure heating block 69. The welding side slope of the pressure plate 64 reduces the volume of the pressure plate and avoids stress concentration at the edge of the traditional flat pressure plate 64, preventing the film from deforming or tearing due to excessive local pressure. The heat dissipation holes 6901 on the mounting plate 68 above the heating block 69 are conducive to heat dissipation of the heating block 69 and at the same time reduce the weight of the welding structure.

[0051] like Figure 12-14As shown, a pressure roller is provided on one side of the welding structure, and a material storage device for non-stop material changing of the cutting machine is provided on the outside of the pressure roller. The material storage device for non-stop material changing of the cutting machine includes a frame, with frame guide rails 73 installed at the four corners of the frame. Side sliders 3 are slidably installed at both ends of the frame guide rails 73. The upper side slider 3 is installed on the rising component connecting plate 92 through a slider connecting plate 79, and the lower side slider 3 is installed on the descending component connecting plate 76 through the same slider connecting plate 79. The side slider 3 and the slider connecting plate 79 are connected. The ascending component connecting plate 92 and the slider connecting plate 79 are connected by screws to the descending component connecting plate 76. A dual-output shaft motor 78 is installed below the descending component connecting plate 76. The dual-output shaft motor 78 is a servo dual-output shaft motor. The output shafts of the dual-output shaft motor 78 are each connected to a bottom drive shaft 77 via a coupling. Upper and lower synchronous pulleys 81 are installed on the bottom drive shafts 77. Upper and lower synchronous pulleys 81 are also installed above the ascending component connecting plate 92. Upper and lower synchronous belts 80 are fitted on the upper and lower synchronous pulleys 81. The bottom transmission shaft 77 is driven by a dual-output shaft motor 78, which transmits power to the upper and lower synchronous pulleys 81 on both sides. When the upper and lower synchronous pulleys 81 move, they drive the upper and lower synchronous belts 80 to move. When the upper and lower synchronous belts 80 move, they pull the rising component connecting plate 92 and the falling component connecting plate 76 to move, thereby moving the tension roller 75 up and down. The lower synchronous belt connecting plate 82 is set on one side of the belt body of the upper and lower synchronous belts 80, and the lower synchronous belt connecting plate 12 is set on the other side of the belt body of the upper and lower synchronous belts 80. This application adopts the form of installing one upper and lower synchronous belt 80 on each side of the frame, and the two upper and lower synchronous belts 80 are driven by the same dual-output shaft motor 78. The transmission is more precise and the error is smaller. It simplifies the structure of the storage device and ensures that the upper and lower synchronous pulleys on both sides of the frame maintain the same speed. The rising component connecting plate 92 and the falling component connecting plate 76 on both sides are evenly stressed and will not be skewed. The transmission structure is simple and reliable and has a long service life.

[0052] The short side of the lower synchronous belt connecting plate 12 is fixedly installed on the rising component connecting plate 92, and the short side of the lower synchronous belt connecting plate 82 is fixedly installed on the falling component connecting plate 76. Installing the upper and lower synchronous belt connecting plates on the short sides does not affect the function of clamping the upper and lower synchronous belts on the long sides, and also facilitates connection with the rising and falling component connecting plates. Driven by the upper and lower synchronous belts 80, the upper and lower synchronous belt connecting plates cause the rising and falling component connecting plates to separate, thus achieving film storage.

[0053] like Figure 15-17 As shown, both the rising assembly connecting plate 92 and the falling assembly connecting plate 76 are provided with U-shaped notches 84; tension rollers 75 are installed on the support plates 85 on both sides of the U-shaped notches 84. The ends of the tension rollers 75 are installed on the support plates 85 by screws. The U-shaped notches 84 increase the amount of tension rollers installed compared to the V-shaped notches, allowing the device to store more adhesive film.

[0054] The support plates 85 on the rising component connecting plate 92 and the U-shaped notches 84 on the falling component connecting plate 76 fit together. The tension rollers 75 on the rising component connecting plate 92 and the falling component connecting plate 76 are distributed in a crisscross pattern. When the tension rollers 75 move up and down with the rising and falling component connecting plates, they can stretch the adhesive film into a serpentine shape, which is beneficial for material changing and material storage during welding.

[0055] The side slider 3 has a sliding cavity containing a ball bearing. The ball bearing engages with the guide groove 86 on the frame guide rail 73. Through the rolling contact design between the ball bearing and the guide groove 86 of the frame guide rail 73, the side slider 3 achieves low-friction, high-precision, and long-life motion performance, thereby improving the service life of the device.

[0056] The lower synchronous belt connecting plate 82 and the lower synchronous belt connecting plate 12 have the same structure, both mainly composed of a side base plate 87 and a cover plate 88. The side base plate 87 is L-shaped, and the cover plate 88 has belt teeth 89, which are engaged in the grooves of the belt. The combination structure of the cover plate 88 and the L-shaped side base plate 87 makes the assembly of the upper and lower synchronous belt connecting plates convenient while minimizing the space occupied in the vertical and horizontal directions.

[0057] The side base plate 87 has a cover plate mounting hole 90 on its long side and an assembly hole 91 on its short side. The belt body of the upper and lower synchronous belts 80 is clamped by the cover plate 88 and the long side of the side base plate 87, which are connected by fasteners. The fasteners are screws. The cover plate 88 and the side base plate 87 are detachably connected by fasteners, which facilitates quick replacement of the upper and lower synchronous belts or maintenance, reducing downtime.

[0058] Tail-end membrane structure Working principle: When the material roll 10 placed on the material roll pallet 9 is transported to the guide rail 6 by the AGV trolley 8, the material roll pallet 9 is placed downwards, and the material roll 10 is positioned on both sides of the material roll pallet 9 and rests on the carrier receiving frame 602. Then, the motor 2 drives the synchronous belt 5 to slide the carrier receiving frame 602 on the guide rail 6 through the L-shaped plate 601 to the position below the clamping plate 7. The clamping plate 7 slides outwards on the guide rail d31 through the slider d30 and slides downwards on the guide rail e34 through the slider e33 to the sides of the material roll. Then, the clamping plate 7 tightens inwards and then moves upwards to unload the material roll 10. When the material roll 10 is unloaded and only the waste paper tube 12 remains; The L-shaped rotating plate 15 is driven by cylinder 14. When cylinder 14 extends or retracts, the L-shaped rotating plate 15 rotates around the rotating rod 13. That is, the L-shaped rotating plate 15 drives the rotating rod 13 to rotate, thereby driving the gripper to rotate above the waste paper tube 12. The slider a17 is driven by cylinder a18 to slide on the guide rail a16, which can change the distance between the grippers to facilitate clamping the waste paper tube 12. The output end of cylinder c24 is connected to the base 28. When cylinder c24 pulls the base 28 outward, the base 28 drives the connecting plate 27. The connecting plate 27 drives the end of the gripper body 25. The gripper body 25 turns and rotates around the rotating shaft 26 to close inward, and the gripper body 25 is in a clamping state. In the first state, the waste paper tube 12 is clamped, and the slide plate 19 is driven by the cylinder b23. The slide plate 19 slides on the guide rail b21 on the base plate 22 via the slider b20, thereby changing the distance between the gripper and the waste paper tube 12. The output end of the cylinder c24 is connected to the base 28. When the cylinder c24 pulls the base 28 outward, the base 28 drives the connecting plate 27, and the connecting plate 27 drives the end of the gripper body 25. The gripper body 25 turns around the rotating shaft 26 and rotates inward to close. The gripper body 25 clamps the waste paper tube 12. The clamping plate 7 releases the waste paper tube 12. Then, the rotating rod 13 is rotated so that the gripper as a whole moves up above the paper tube storage assembly 11. Then the gripper is released, completing one material change operation. After the material change is completed, when the clamping plate 7 releases the material roll 1, the material head of the material roll 1 is downward. The drive motor 26 and cylinder d21 make the material head fall exactly inside the guide plate 402. The guide plate 402 and the moving plate 4 are fixed together with bolts. The cylinder a5 drives the moving plate 4 away from the fixed plate 3. When the material head falls between the two and continues to fall downward, when the signal of the photoelectric sensor 13 is blocked, the moving plate 4 moves closer to the fixed plate 3, so that the material head is clamped. The rotating cylinder 14 rotates the whole in the direction away from the material roll 1 by 90°. Then the cylinder b7 drives the receiving plate 6 so that the end of the receiving plate 6 is close to the material head. At the same time, the drive motor 2 and cylinder d21 adjust the position of the receiving plate 6 so that the part of the material head exposed on the receiving plate 6 is in a rigid state, which facilitates the welding work of the material tail and the material head in the next process. When the material tail is uneven, the material tail is cut evenly by the cooperation between the cutter 60 and the slot 65 of the pressure plate 64. When the material tail is cut, there is a pressing plate and a cylinder behind the pressure roller 72 to press the film so that the cutter can cut it. Then, the position of the clamping device is adjusted by the displacement device until the material head and material tail of the new material roll 1 overlap at the position of the heating base plate 70. Then, the mounting plate 68 is driven by the welding cylinder 67, and the heating block 69 then welds the material head and material tail. After the welding is completed, it passes through the pressure roller 72 to the next process. The adhesive film exiting from the pressure roller 72 passes between the tension roller 75 of the rising component connecting plate 92 and the falling component connecting plate 76 of the material storage device for material changing without stopping the machine. At this time, the rising component connecting plate 92 and the falling component connecting plate 76 are engaged together. Then, the dual output shaft motor 78 is started, and the adhesive film in the middle is stretched into a serpentine shape. Due to the lengthening of the movement path, more adhesive film stays in the mechanism, which plays a role in temporary material storage. In this way, the machine stoppage caused by material changing and welding at the front end will not affect the subsequent output. When the front end process is completed, the adhesive film in the storage mechanism is basically consumed. The dual output shaft motor 78 will slowly move the tension roller 75 towards the middle through transmission control, and the device will stop working. After the film rolled out of the cutting machine is stored in the material changing device without stopping the machine, it is stretched by the robotic arm clamp of the tail film pulling structure, and then covered onto the tempered glass with the lower conveying device.
