Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic laminators, in particular to a laminator reeling and unreeling material feeding mechanism. Background Art

[0002] Photovoltaic laminator is a key equipment in the production process of photovoltaic modules. Its main function is to laminate and package the laid multi-layer materials, such as solar cells, EVA films, glass, backplanes, etc., under vacuum, high temperature and certain pressure conditions to make them a solid, sealed and high-performance whole. In the production process of photovoltaic laminator, precise control of material feeding and efficient winding and unwinding are crucial to product quality and production efficiency.

[0003] At present, the unwinding and reeling device used in the laminating machine needs a tension adjustment function to ensure that the film material can maintain the appropriate tension and be flatly applied to the photovoltaic glass during lamination. However, when the unwinding and reeling device of the existing laminating machine adjusts the tension of the film material, it mainly uses friction to squeeze the roller of the winding wheel and then reduces the rotation speed of the unwinding and reeling wheel frame, so that the film can restore the appropriate tension after receiving the traction force. Secondly, the extrusion roller set on the object can also be used to squeeze the film discharge position so that it requires a larger traction force to continue to feed the material, thereby achieving the effect of adjusting the material tension. In summary, the existing tension adjustment method mainly changes the speed of the winding wheel through friction and squeezes the material through extrusion force to achieve the effect of adjusting the material winding tension. The method of using friction will cause damage to the roller and reduce the service life of the equipment. The extrusion method will cause fatal damage to more fragile materials and affect product quality.

[0004] The existing rewinding and unwinding material feeding mechanisms often have problems such as unstable material feeding, inaccurate tension control, and uneven rewinding and unwinding speeds during operation, which affects the lamination effect and production efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, a strong impact airflow is generated by the air pump, and the direction of the air pump can be adjusted by cooperating with the fourth electric push rod, the rotating seat, and the tail rod. When the airflow impacts the fan plate, it can achieve the effect of acceleration and deceleration, and the second connecting component cooperates with the first connecting component to finally achieve the effect of controlling the acceleration and deceleration of the winding rack.

[0018] 2. When the present invention is in use, when the winding rack needs to be replaced, the piston rod at the end of the third electric push rod inside the mounting plate can be started to contract, thereby pulling the movable cross bar to move upward inside the mounting plate. At this time, the two second rotating pins and the two connecting rods on the surface of the movable cross bar rotate, and one end of the connecting rod is also pulled to move upward, while the other end of the connecting rod rotates with the first rotating pin on the extension block. Finally, the connecting rod forms a horizontal state and pushes the extension block and the two mounting racks away from each other, so that the distance between the two rotating sleeves installed on the mounting rack is greater than the length of the rotating steel shaft, thereby causing the winding rack and the rotating steel shaft to fall off. The installation can be carried out through the reverse steps. The design structure is simple, the friction damage is lower than that of the gear screw transmission method, and it is stable and reliable.

[0019] 3. When the present invention is used, when removing the rotating steel shaft, the outer ends of the two support rods at the bottom of the mounting plate can be pulled forward, and the support rods will rotate forward under the action of the rotating rods. When the support rods and the mounting plate form a vertical state, their surfaces will adhere to and be adsorbed by the magnetic blocks, thereby having good stability. At this time, the rotating steel shaft will fall on the two support rods after being removed, and will not fall directly downward, which effectively increases the difficulty of removing the winding frame and improves the use effect.

[0020] 4. When the present invention is in use, the rectangular shell is inserted into the rectangular sleeve on the surface of the mounting frame, and the two are connected by a card slot and a buckle. When installing, it can be installed by pressing. When removing, the speed control component can be removed by pressing the end of the buckle to disengage it from the card slot and then pulling out the rectangular shell. This facilitates the removal, replacement and maintenance of the speed control component at a later time, and the maintenance difficulty is relatively low. The two first wind shields and the second wind shield on the surface of the rectangular shell play a role of shielding the area around the fan plate, and cooperate with the third wind shield on the surface of the circular block to form two air ducts, which can guide the airflow blown out by the air pump to ensure that the airflow acts on the fan blades, thereby effectively adjusting the tension of the material.

The end of the rotating steel shaft 301 is inserted into the inner groove 602 and the anti-skid patterns 303 and the anti-skid pad 604 cooperate with each other. The front surface of the frame 1 is located above the winding frame 25 and is rotatably connected to the first roller 11 through a bracket installed with a correction photoelectric sensor 12. The front surface of the frame 1 is rotatably connected to the second roller 13 near the top center through a bracket. The front surface of the frame 1 is rotatably connected to the fourth roller 16 near the center through a bracket. The front surface of the frame 1 is located below the fourth roller 16 and is rotatably connected to the third roller 14 through a bracket rotatably connected to the first electric push rod 15, and the tail end of the first electric push rod 15 is rotatably connected to the front surface of the frame 1.A pressure sensor 20 is installed between the brackets of the first electric push rod 15 and the third roller 14. A second electric push rod 19 is installed on the front surface of the frame 1 near the fourth roller 16. The top of the second electric push rod 19 is rotatably connected to a swing frame 17. One end of the swing frame 17 is rotatably connected to the front surface of the frame 1 and the other end is rotatably connected to the fifth roller 18. The outer surface of one side of the frame 1 is rotatably connected to the sixth roller 22 through a bracket. An external adjustment roller 23 is arranged below the frame 1.

[0025] In this embodiment, when the photovoltaic laminator uses this mechanism to feed materials, a winding rack 25 wrapped with film material and an empty winding rack 25 are respectively inserted into the corresponding rotating steel shaft 301, and then the extrusion nuts 302 at both ends are tightened to clamp them, and the two ends of the rotating steel shaft 301 are inserted into the inner groove 602 of the rotating sleeve 601 in the corresponding set of mounting frames 402. Under the action of the anti-skid pattern 303 at the end of the rotating steel shaft 301 and the anti-skid pad 604 in the inner groove 602, the rotating steel shaft 301 can rotate between the two mounting frames 402, and then the surface film material is sequentially rolled from above the first roller 11 on the frame 1, above the second roller 13, between the fourth roller 16 and the third roller 14, above the fifth roller 18, and between the sixth roller 19. The film material passes through the outer side of 22 and under the external adjustment roller 23 on the laminator, and the other end of the film material is wound on another empty winding rack 25 in the same way. Then, the external adjustment roller 23 is lowered to squeeze the film material to fit closely to the surface of the photovoltaic glass continuously conveyed on the laminator. Under the action of friction, the film material is pulled out from the winding rack 25 and adhered to the surface of the photovoltaic glass for laminated packaging to form a solid, sealed, and high-performance whole. In the process of the film material being pulled out, the deviation correction photoelectric sensor 12 will continuously monitor the position of the passing material, and cooperate with the electric slide 24 to adjust the position of the winding rack 25 and then correct the position. The tension detector integrated on the second rotating roller 13 continuously detects the tension of the material. , and converts it into an electrical signal and sends it to the PLC controller in the laminating machine equipment. For materials that are not easily damaged, the first electric push rod 15 changes the extrusion force between the fourth roller 16 and the third roller 14 on the material by pushing and pulling the third roller 14, and then adjusts the tension of the material in real time, and the second electric push rod 19 changes the height of the fifth roller 18 by pushing and pulling the swing frame 17 up and down, and then plays a role in tightening the material to keep it in a taut state. The sixth roller 22 expands the material to avoid contact between the material and the frame 1, thereby ensuring that the material can be flat and fit with the photovoltaic glass. For fragile film-type materials that are loose and too tight, the air pump 903 is started to compress the air and spray it out from the outlet. At this time, the airflow will impact On the fan plate 805 rotating with the rotating steel shaft 301, when the airflow impact direction is opposite to the rotation direction of the fan plate 805, the fan plate 805 will decelerate and drive the circular block 801 to decelerate through the circular shell 804. After the circular block 801 is decelerated, it will drive the rotating sleeve 601 on the rear side to decelerate synchronously through the plug post 802. The anti-skid pad 604 inside the rotating sleeve 601 and the anti-skid pattern 303 at the end of the rotating steel shaft 301 cooperate, so the rotating steel shaft 301 will decelerate synchronously with the rotating sleeve 601, thereby reducing the rotation speed of the winding frame 25. At this time, the film material wrapped on the outside of the winding frame 25 requires a larger pulling force to be pulled out, and the larger pulling force can make the film material retighten. When the material is in an overly tight state,Starting the fourth electric push rod 905 to extend and retract can generate a push-pull force on one end of the tail rod 904, thereby causing the turntable 901 to rotate forward and backward, thereby achieving the effect of adjusting the direction of the air outlet of the air pump 903. At this time, after starting the air pump 903 and the airflow ejected is consistent with the rotation direction of the fan plate 805, the effect of accelerating the rotation of the winding frame 25 can be achieved, thereby gradually relaxing it. The design structure is novel in function and has perfectly solved the problem that adjusting the tension by friction will damage the equipment and adjusting the tension by extrusion will damage the fragile materials. It has a good use effect and great economic value. When installing the speed control component 8, the circular shell 804 is pressed on the circular block 801 that is rotatably connected by the bearing and the rectangular shell 703, and then the bolt 803 is passed through the circular shell 804 and tightened to tighten the circular shell 804 and the circular block 801, so that the two rotate synchronously. At this time, the plug 802 will be synchronously inserted into the rear end of the corresponding rotating sleeve 601 to make the fan plate 805 and the rotating sleeve 601 rotate synchronously, thereby completing the installation.

[0026] Embodiment 2: Figure 1-Figure 13 As shown, the drive assembly 5 includes a third electric push rod 501, which is fixedly mounted on the inner top of the mounting plate 401 with the telescopic end facing downward, and the telescopic end of the third electric push rod 501 is fixedly connected to a movable cross bar 502 through a connecting piece, and a second rotating pin 503 is symmetrically fixedly connected to the outer surface of one side of the movable cross bar 502 near the edge, and the outer surface of the second rotating pin 503 is rotatably connected to a connecting rod 504, and the other end of the connecting rod 504 is rotatably connected to the first rotating pin 404, and a turntable 901 is rotatably connected to the rear surface of one of the mounting frames 402, and a tail rod 904 extends from the outer surface of the turntable 901, and one end of the tail rod 904 is rotatably connected to a fourth electric push rod 905, and the tail end of the fourth electric push rod 905 is rotatably connected to a rotating seat 906, and the rotating seat 906 is fixedly mounted on the rear surface of one of the mounting frames 402.

[0027] In this embodiment, when the winding rack 25 needs to be replaced, the piston rod at the end of the third electric push rod 501 inside the mounting plate 401 can be activated to retract, thereby pulling the movable cross bar 502 to move upward inside the mounting plate 401. At this time, the two second rotating pins 503 and the two connecting rods 504 on the surface of the movable cross bar 502 rotate, and also pull one end of the connecting rod 504 to move upward, while the other end of the connecting rod 504 rotates with the first rotating pin 404 on the extension block 403. Finally, the connecting rod 504 forms a horizontal state and pushes the extension block 403 and the two mounting racks 402 away from each other, so that The distance between the two rotating sleeves 601 installed on the mounting frame 402 is greater than the length of the rotating steel shaft 301, so that the winding frame 25 and the rotating steel shaft 301 can be detached. The installation can be carried out by the reverse steps. The design structure is simple, the friction damage is lower than that of the gear screw transmission method, and it is stable and reliable, which improves the disassembly, assembly and replacement efficiency of the winding frame 25. The cover plate 405 is installed on the surface of the mounting plate 401 to shield and protect the drive component 5. The height raising frame 902 is mainly used to install the air pump 903 on the surface of the turntable 901 and make the height of the air pump 903 and the fan plate 805 adaptable.

[0028] Embodiment 3: Figure 1-Figure 13 As shown, a magnetic block 26 is fixedly connected at the bottom center of the mounting plate 401, and rotating rods 27 are symmetrically installed at the positions on both sides of the magnetic block 26 at the bottom of the mounting plate 401. The outer surface of the rotating rod 27 is rotatably connected to a supporting rod 28, and the supporting rod 28 is bent and magnetically connected to the magnetic block 26. A rectangular sleeve 701 is sleeved on the outer surface of the rectangular shell 703 near the front side, and the rectangular sleeve 701 is fixedly connected to the rear surface of one of the mounting frames 402. The top and A card slot 702 is provided at the bottom, and deformable card buckles 704 are provided on the top and bottom of the rectangular shell 703. The card buckle 704 and the card slot 702 are snap-fitted together. A plug post 802 is fixedly connected to the center of the front surface of the circular block 801. The plug post 802 and the rear end of one of the rotating sleeves 601 form an insert connection. The rear surface of the circular block 801 is threadedly connected with a bolt 803 for fixing the circular shell 804. The rear surface of the circular shell 804 is fixedly connected with a third windshield 806 with a hollow center.

[0029] In this embodiment, when removing the rotating steel shaft 301, the outer ends of the two supporting rods 28 at the bottom of the mounting plate 401 can be pulled forward. At this time, the supporting rod 28 will rotate forward under the action of the rotating rod 27. When the supporting rod 28 and the mounting plate 401 form a vertical state, its surface will be attached to and adsorbed by the magnetic block 26, thereby having good stability. At this time, the rotating steel shaft 301 will fall on the two supporting rods 28 after being removed, and will not fall directly downward, which effectively increases the difficulty of removing the winding rack 25 and improves the use effect. The bent supporting rod 28 can effectively prevent the fallen winding rack 25 from rolling down from the end. The speed control component 8 is rotatably connected to the rectangular shell 703 through the bearing, and the rectangular shell 703 is inserted into the mounting rack 4 02 surface, and the two are connected by the slot 702 and the buckle 704, which can be installed by pressing. When removing, press the end of the buckle 704 to disengage it from the slot 702, and then pull out the rectangular shell 703 to complete the removal of the speed control component 8, which is convenient for the later removal, replacement and maintenance of the speed control component 8, and the maintenance difficulty is relatively low. The two first wind shields 705 and the second wind shield 706 on the surface of the rectangular shell 703 play the role of shielding the area around the fan plate 805, and cooperate with the third wind shield 806 on the surface of the circular block 801 to form two air ducts, which can guide the airflow blown out by the air pump 903 to ensure that the airflow acts on the fan blades, thereby effectively adjusting the tension of the material.

[0030] Working principle: When the photovoltaic laminator uses this mechanism to feed materials, the winding rack 25 wrapped with film materials and an empty winding rack 25 are respectively inserted into the corresponding rotating steel shaft 301, and then the extrusion nuts 302 at both ends are tightened to clamp them, and the two ends of the rotating steel shaft 301 are inserted into the inner groove 602 of the rotating sleeve 601 in the corresponding set of mounting frames 402. Under the action of the anti-skid pattern 303 at the end of the rotating steel shaft 301 and the anti-skid pad 604 in the inner groove 602, the rotating steel shaft 301 can rotate between the two mounting frames 402, and then the surface film material is sequentially rolled from above the first roller 11 on the frame 1, above the second roller 13, between the fourth roller 16 and the third roller 14, above the fifth roller 18, and the sixth roller 2 2 passes under the external adjustment roller 23 on the outside and laminator, and in the same way, the other end of the film material is wound on another empty winding rack 25, and then the external adjustment roller 23 is lowered to squeeze the film material to fit closely to the surface of the photovoltaic glass continuously conveyed on the laminator. Under the action of friction, the film material will be pulled out from the winding rack 25 and attached to the surface of the photovoltaic glass for lamination and packaging, so that it forms a solid, sealed, and good-performance whole. In the process of the film material being pulled out, the deviation correction photoelectric sensor 12 will continuously monitor the position of the passing material, and cooperate with the electric slide 24 to adjust the position of the winding rack 25 and then correct the position. The tension detector integrated on the second rotating roller 13 continuously detects the tension of the material. , and converts it into an electrical signal and sends it to the PLC controller in the laminating machine equipment. For materials that are not easily damaged, the first electric push rod 15 changes the extrusion force between the fourth roller 16 and the third roller 14 on the material by pushing and pulling the third roller 14, and then adjusts the tension of the material in real time, and the second electric push rod 19 changes the height of the fifth roller 18 by pushing and pulling the swing frame 17 up and down, and then plays a role in tightening the material to keep it in a taut state. The sixth roller 22 expands the material to avoid contact between the material and the frame 1, thereby ensuring that the material can be flat and fit with the photovoltaic glass. For fragile film-type materials that are loose and too tight, the air pump 903 is started to compress the air and spray it out from the outlet. At this time, the airflow will impact On the fan plate 805 rotating with the rotating steel shaft 301, when the airflow impact direction is opposite to the rotation direction of the fan plate 805, the fan plate 805 will decelerate and drive the circular block 801 to decelerate through the circular shell 804. After the circular block 801 is decelerated, it will drive the rotating sleeve 601 on the rear side to decelerate synchronously through the plug post 802. The anti-skid pad 604 inside the rotating sleeve 601 and the anti-skid pattern 303 at the end of the rotating steel shaft 301 cooperate, so the rotating steel shaft 301 will decelerate synchronously with the rotating sleeve 601, thereby reducing the rotation speed of the winding frame 25. At this time, the film material wrapped on the outside of the winding frame 25 requires a larger pulling force to be pulled out, and the larger pulling force can make the film material retighten. When the material is in an overly tight state,Starting the fourth electric push rod 905 to extend and retract can generate a push-pull force on one end of the tail rod 904, thereby causing the turntable 901 to rotate forward and backward, thereby achieving the effect of adjusting the direction of the air outlet of the air pump 903. At this time, after starting the air pump 903 to spray out an airflow that is consistent with the rotation direction of the fan plate 805, the effect of accelerating the rotation of the winding frame 25 can be achieved, thereby gradually relaxing it. This design structure has novel functions and perfectly solves the problem that using friction force to adjust tension will damage equipment and using extrusion force to adjust tension will damage fragile materials. It has a good use effect and has great economic value. When the take-up frame 25 needs to be replaced, the piston rod at the end of the third electric push rod 501 inside the mounting plate 401 can be started to contract, thereby pulling the movable cross bar 502 to move upward inside the mounting plate 401. At this time, the two second rotating pins 503 and the two connecting rods 504 on the surface of the movable cross bar 502 rotate, and one end of the connecting rod 504 is also pulled upward, while the other end of the connecting rod 504 rotates with the first rotating pin 404 on the extension block 403. Finally, the connecting rod 504 forms a horizontal state and pushes the extension block 403 and the two mounting frames 402 away from each other, so that the distance between the two rotating sleeves 601 installed on the mounting frame 402 is greater than the length of the rotating steel shaft 301, thereby causing the take-up frame 25 and the rotating steel shaft 301 to fall off. The installation can be carried out by the reverse steps. The design structure is simple, the friction damage is lower than that of the gear screw transmission method, and it is stable and reliable, which improves the efficiency of disassembly, assembly and replacement of the take-up frame 25. In addition, when removing the rotating steel shaft 301, the outer ends of the two support rods 28 at the bottom of the mounting plate 401 can be pulled forward. At this time, the support rods 28 will rotate forward under the action of the rotating rods 27. When the support rods 28 and the mounting plate 401 form a vertical state, their surfaces will adhere to and be adsorbed by the magnetic blocks 26, thereby having good stability. At this time, the rotating steel shaft 301 will fall on the two support rods 28 after being removed, and will not fall directly downward, which effectively increases the difficulty of removing the winding frame 25 and improves the use effect.
