Description

Technical Field

[0001] This invention relates to the field of film cutting technology, and more specifically to a film cutting and laying device and its usage method. Background Technology

[0002] Photovoltaic module encapsulation is a core technology in the entire module manufacturing industry. During the production process, a sticky thermosetting adhesive (EVA) is used to place between the laminated glass to ensure a tight bond between the glass surface and the solar cells, and to ensure that the core component, the solar cells, is cushioned by double-layer EVA material. The tempered glass and the backsheet material on the back side greatly enhance the module's impact resistance and aging resistance.

[0003] Currently, the mainstream thin-film laying process in the photovoltaic module manufacturing industry is rough cutting + fine cutting + laying process. However, most existing equipment forms a single sheet of film after the material roll is rough cut. The film waits on the rough cutting platform for the robot to transfer it to the fine cutting table. The fine cutting table is equipped with fine cutting blades around the four sides to cut off the four sides and obtain a film with precise dimensions on all four sides. Then the robot lays the film onto the glass.

[0004] The main problems with this type of equipment are: 1. The equipment process is complex, and the three machines plus the transfer robot occupy too much space; 2. The thin film is prone to slippage after being laid on the glass. Currently, most methods use hot-pressing the four corners of the thin film onto the glass, but this method is very ineffective in actual use. The hot-pressing points are too small and the adhesion is insufficient. Moreover, after the hot-pressing points harden, the silicon wafers are prone to cracking when laid later; 3. Due to glass shape errors or the precision of the equipment itself, the laying accuracy is difficult to achieve the current industry requirement of ±0.5mm; 4. The existing equipment has a slow cycle time, which is difficult to meet the increasingly fast photovoltaic production lines. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a simple and easy-to-use thin film cutting and laying device, which can be used for the precise cutting and laying of photovoltaic thin films. The present invention eliminates the material transfer action of the transfer robot, and the film is directly laid on the glass. Then, the precise position is obtained through correction. The setting of the electrostatic generator can emit electrostatic ions on the glass and the film on the glass, so that the film is tightly adsorbed on the glass and will not slip on the subsequent production line, thereby ensuring product quality.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a film cutting and laying device, comprising a high-speed edge cutter and a correction cross-cutting machine, wherein the film to be cut and laid passes sequentially through the high-speed edge cutter and the correction cross-cutting machine, characterized in that: the high-speed edge cutter includes a feeding mechanism, a cutting mechanism, a film pulling mechanism, and a transverse conveying mechanism, the high-speed edge cutter is used to coarsely cut the film roll into films of corresponding sizes, and simultaneously lay the film on the first conveying line in the transverse conveying mechanism; the correction cross-cutting machine includes a correction conveying mechanism, a leveling mechanism, a secondary cross-cutting mechanism, a lifting suction cup mechanism, and an electrostatic generator, the correction cross-cutting machine is used to perform secondary cutting on the film on the glass conveyed from the first conveying line, and before laying, the position of the glass is corrected according to the vision camera in the secondary cross-cutting mechanism to achieve the purpose of high-precision laying.

[0007] Furthermore, a gap is provided between the high-speed edge cutting machine and the cross-cutting machine; the cutting mechanism includes a lifting and buffering mechanism, an edge cutting mechanism, a punching mechanism, a spacing mechanism, a feeding mechanism, and a primary cross-cutting mechanism. The film from the feeding mechanism passes through the lifting and buffering mechanism, the edge cutting mechanism, the punching mechanism, the spacing mechanism, the feeding mechanism, and the primary cross-cutting mechanism in sequence, and is pulled out by the film pulling mechanism and laid on the glass that has been positioned in the transverse conveying mechanism.

[0008] Furthermore, the edge cutting mechanism includes a shifting guide rail, an edge cutting blade assembly, an edge cutting bottom blade, an edge cutting servo motor, and an edge cutting drive shaft. The two ends of the edge cutting drive shaft are rotatably mounted on the mounting base. The edge cutting servo motor drives the edge cutting drive shaft to rotate. The edge cutting bottom blade is mounted on the edge cutting drive shaft and rotates with it. The shifting guide rail is mounted on the upper part of the mounting base and located on the edge cutting drive shaft. The edge cutting blade assembly is movably mounted on the shifting guide rail and can move to any position on the shifting guide rail. The edge cutting blade assembly and the edge cutting bottom blade form a scissor structure to cut the edge material of the passing film. The two longitudinal edges of the film are cut when they pass through the edge cutting mechanism.

[0009] Furthermore, the punching mechanism includes multiple punching blades; the distance-fixing mechanism includes a distance-fixing servo motor, a rotating shaft, synchronous pulleys, a linear guide rail I, a roller, a laser rangefinder, and a synchronous belt I, which drives the rotation. Synchronous pulleys are installed at both ends of the rotating shaft, which is connected to the output shaft of the distance-fixing servo motor. The synchronous belt I is connected to the synchronous pulleys, and the roller is connected to the synchronous belt I. The synchronous pulleys drive the synchronous belt I to move, and under the drive of the synchronous belt I, the roller moves up and down along the linear guide rail I. The laser rangefinder is installed on the frame above the roller to measure the height of the roller. By controlling the height of the roller through the servo motor, the distance from the punching position of the punching blade to the position of the first cross-cutting blade can be controlled by the height of the roller. This allows the punching action and the first cross-cutting action to be performed simultaneously, improving the equipment speed.

[0010] Furthermore, the primary cross-cutting mechanism includes a fixed frame, a cross-cutting drive cylinder, a lower guillotine, an upper guillotine, a film-pressing cylinder I, and a film-pressing plate I. The fixed ends of both the cross-cutting drive cylinder and the film-pressing cylinder I are mounted on the fixed frame. Both ends of the lower guillotine are fixedly connected to the fixed frame. The upper guillotine is mounted on the movable end of the cross-cutting drive cylinder. The cross-cutting drive cylinder drives the upper guillotine to move up and down. When the upper guillotine moves downwards, it forms a scissor structure with the lower guillotine, completing the film cutting. The film-pressing plate I is mounted on the movable end of the film-pressing cylinder I. The film-pressing cylinder I drives the film-pressing plate I to move up and down. Simultaneously, before cutting, the film-pressing cylinder I drives the film-pressing plate I downwards to assist in the cutting action, making the film flat before performing a second cross-cut.

[0011] Furthermore, the transverse conveying mechanism includes a conveyor line, a centering and straightening mechanism, a blocking mechanism, and a hand-operated passageway. The blocking mechanism is arranged in the running direction of the conveyor line, the centering and straightening mechanism is set on both sides of the conveyor line to straighten the glass on the conveyor line, and the hand-operated passageway is set in front of the transverse conveying mechanism for connecting to the cross-cutting machine.

[0012] Furthermore, the correction conveying mechanism includes a second conveying line, a servo shifting mechanism, and a pneumatic shifting mechanism. Two sets of servo shifting mechanisms are arranged in front of and to the left of the second conveying line in the direction of operation, and two sets of pneumatic shifting mechanisms are arranged behind and to the right of the second conveying line in the direction of operation. The glass from the high-speed edge cutting machine is connected to the correction cross-cutting machine via the second conveying line.

[0013] Furthermore, the leveling mechanism includes a leveling drive servo motor, a synchronous belt II, a film pressing module, a leveling module, a profile frame, and a linear guide rail II. The linear guide rail II is mounted on the profile frame. The film pressing module and the leveling module are respectively arranged on both sides of the profile frame. The leveling drive servo motor drives the synchronous belt to move, and the synchronous belt drives the leveling module to move along the linear guide rail II towards the center. The film pressing module includes a film pressing cylinder II and a film pressing plate II. The fixed end of the film pressing cylinder II is mounted on the profile frame, and the movable end of the film pressing cylinder II is mounted on the film pressing plate II. The film pressing cylinder II drives the film pressing plate II to move up and down. The leveling module includes a leveling lifting cylinder and a leveling plate. The fixed end of the leveling lifting cylinder is mounted on the profile frame, and the movable end of the leveling lifting cylinder is mounted on the leveling plate. The leveling lifting cylinder drives the leveling plate to move up and down.

[0014] Furthermore, the secondary cross-cutting mechanism includes a rack, guide rail, cutter shifting servo motor, secondary cross-cutting blade, vision camera, and receiving box. The cutter shifting servo motor drives the secondary cross-cutting blade to move along the guide rail and rack to an accurate position, where it performs a secondary cut on the film. A vision camera is placed next to the secondary cross-cutting blade to detect the offset position of the film from the glass. A receiving box is arranged below the secondary cross-cutting blade to collect waste material after the secondary cross-cutting. The lifting suction cup mechanism includes a suction cup frame, lifting servo motor, lifting frame, and fixed frame. The bottom surface of the suction cup frame is equipped with suction cups, and the top surface of the suction cup frame is connected to one end of the lifting frame. The lifting frame is connected to the lifting servo motor, and the fixed frame is horizontally connected to the cross-cutting machine. The lifting servo motor is fixedly connected to the fixed frame. An electrostatic generator is installed at the outlet of the cross-cutting machine.

[0015] The present invention also relates to a method of using a film cutting and laying device, wherein the method of using the aforementioned film cutting and laying device is as follows:

[0016] S1. The film from the feeding mechanism passes sequentially through the lifting and buffering mechanism, the edge cutting mechanism, the punching mechanism, the spacing mechanism, the ejection mechanism, and the first transverse cutting mechanism. The film is then pulled out by the film pulling mechanism and laid onto the glass that has been positioned in the transverse conveying mechanism. During the film pulling process, the film undergoes an edge cutting action. The edge cutting knife group can move to any position on the shifting guide rail. The edge cutting knife group and the edge cutting bottom knife form a scissor structure to cut the edge material of the passing film. The two longitudinal edge cutting positions of the film are cut when it passes through the edge cutting mechanism.

[0017] S2. By controlling the height of the rollers through a servo motor, the distance from the punching position of the punching knife to the first cross-cutting position can be controlled by the height of the rollers, so that the punching action and the first cross-cutting action can be performed simultaneously, thereby improving the speed of the equipment.

[0018] S3. Before cutting, the pressure cylinder I drives the pressure plate I to move downward to complete the auxiliary action of cutting, so that the film is flat and then cross-cutting is performed; when the upper guillotine moves downward, it forms a scissor structure with the lower guillotine to complete the cutting of the film, that is, the first cross-cutting position, cutting the roll into a sheet.

[0019] S4. After one cross-cutting operation is completed, the film is first laid on the glass on the first conveyor line, and then conveyed by the first conveyor line to the second conveyor line of the cross-cutting machine.

[0020] S5, S5, the glass is first positioned by the four-sided shifting mechanism on the second conveyor line, and then photographed by a vision camera; after the photograph is taken, the film on the glass is sucked up by the suction cup frame above and lifted to the highest position. At the same time, the industrial control computer starts to calculate the correction position based on the photograph results. The calculation results are sent to the PLC controller, and then the PLC controller controls the four-sided shifting mechanism of the glass to reposition the glass; the film on the glass being sucked up by the suction cup frame above is equivalent to fixing the position of the film. After the shifting mechanism repositions the glass, the relative position of the glass and the film is calibrated.

[0021] S6. The suction cup holder lowers the film to the secondary cross-cutting position for secondary cutting, and the waste material falls into the receiving box;

[0022] S7. The suction cup holder continues to descend, and then the film is applied to the glass that has been positioned and corrected.

[0023] S8. The leveling mechanism starts to operate. First, the film pressing module presses the film, and then the leveling module performs a leveling action to eliminate the bulges that occur after the film is applied to the glass.

[0024] S9. The second conveyor line will discharge the laid glass, and at the same time, the electrostatic generator above the cross-cutting machine will activate to emit electrostatic ions onto the film and glass, so that the film is tightly adsorbed onto the glass.

[0025] The advantages of using the technical solution of this invention are:

[0026] 1. This invention eliminates the material transfer action of the transfer robot. The film is directly applied to the glass and then the precise position is obtained through correction. The electrostatic generator can emit electrostatic ions to the glass and the film on the glass, so that the film is tightly adsorbed on the glass and will not slip on the subsequent production line, thus ensuring product quality.

[0027] 2. This invention completes the edge cutting on both sides on the rough cutting machine. Then, since the film will deform due to the stretching action in the length direction, a second cutting is performed in the length direction on the next machine to obtain the correct film size. In addition, a sweeping mechanism is added to solve the bulging problem. Traditional fine cutting machines have a slow cycle time and a large footprint. This technical solution improves the cycle time, reduces the footprint, and lowers the cost. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0056] like Figures 1 to 14 As shown, a film cutting and laying device includes a high-speed edge cutter 1 and a cross-cutting machine 5. The film to be cut and laid passes through the high-speed edge cutter 1 and the cross-cutting machine 5 in sequence. The high-speed edge cutter 1 includes a feeding mechanism 100, a cutting mechanism 200, a film pulling mechanism 300, and a transverse conveying mechanism 17. The high-speed edge cutter 1 is used to roughly cut the film roll into films of the corresponding size, and at the same time lay the film on the first conveying line 171 in the transverse conveying mechanism 17. The cross-cutting machine 5 includes a cross-cutting conveying mechanism 51, a leveling mechanism 52, a secondary cross-cutting mechanism 53, a lifting suction cup mechanism 54, and an electrostatic generator 55. The cross-cutting machine 5 is used to perform secondary cutting on the film on the glass conveyed from the first conveying line 171, and before laying, it corrects the position of the glass according to the vision camera 535 in the secondary cross-cutting mechanism 53 to achieve the purpose of high-precision laying.

[0057] The high-speed side cutting machine 1 consists of a feeding mechanism 100, a cutting mechanism 200, a film stretching mechanism 300, and a transverse conveying mechanism 17. The feeding mechanism 100 and the film stretching mechanism 300 are common mechanisms in this industry, and will not be described in detail here.

[0058] A gap is provided between the high-speed edge cutting machine 1 and the straightening cross-cutting machine 5; the cutting mechanism 200 includes a lifting buffer mechanism 11, an edge cutting mechanism 12, a punching mechanism 13, a spacing mechanism 14, a feeding mechanism 15 and a primary cross-cutting mechanism 16. The film from the feeding mechanism 100 passes through the lifting buffer mechanism 11, the edge cutting mechanism 12, the punching mechanism 13, the spacing mechanism 14, the feeding mechanism 15 and the primary cross-cutting mechanism 16 in sequence, and is pulled out by the film pulling mechanism 300 and laid on the glass that has been positioned in the transverse conveying mechanism 17.

[0059] The edge cutting mechanism 12 includes a shift guide rail 121, an edge cutting blade assembly 122, an edge cutting bottom blade 123, an edge cutting servo motor 124, and an edge cutting drive shaft 125. The two ends of the edge cutting drive shaft 125 are rotatably mounted on the mounting base 126. The edge cutting servo motor 124 drives the edge cutting drive shaft 125 to rotate. The edge cutting bottom blade 123 is mounted on the edge cutting drive shaft 125 and rotates with it. The shift guide rail 121 is mounted on the upper part of the mounting base 126 and is located on the edge cutting drive shaft 125. The edge cutting blade assembly 122 is movably mounted on the shift guide rail 121. The edge cutting blade assembly 122 can move to any position on the shift guide rail 121. The edge cutting blade assembly 122 and the edge cutting bottom blade 123 form a scissor structure to cut the edge material of the passing film. The two longitudinal edge cutting positions 1003 of the film are cut when passing through the edge cutting mechanism 12.

[0060] Specifically, the edge-cutting drive shaft 125 is driven by the edge-cutting servo motor 124, and the edge-cutting bottom blade 123 rotates together with the edge-cutting drive shaft 125. A shifting guide rail 121 is fixed above the edge-cutting drive shaft 125, and an edge-cutting blade assembly 122 is mounted on the shifting guide rail 121. The edge-cutting blade assembly 122 can move to any position on the shifting guide rail 121. The edge-cutting blade assembly 122 and the edge-cutting bottom blade 123 form a scissor structure to cut the edge material of the passing film. Figure 14 As shown, the two longitudinal edge cutting positions 1003 of the film are cut when passing through the edge cutting mechanism 12.

[0061] The punching mechanism 13 includes multiple punching cutters 131; the distance-fixing mechanism 14 includes a distance-fixing servo motor 141, a rotating shaft 142, synchronous pulleys 143, a linear guide rail I 144, a roller 145, a laser rangefinder 146, and a synchronous belt I 147, which drives the rotation. Synchronous pulleys 143 are installed at both ends of the rotating shaft 142, which is connected to the output shaft of the distance-fixing servo motor 141. The synchronous belt I 147 is connected to the synchronous pulleys 143, and the roller 145 is connected to the synchronous belt I 147. The distance-fixing servo motor 141 drives the rotating shaft 142 to rotate. Two synchronous pulleys 143 are fixed on both sides of the rotating shaft 142. The synchronous pulleys 143 drive the synchronous belt I 147 to move. Under the drive of the synchronous belt I 147, the roller 145 moves up and down along the linear guide rail I 144. The laser rangefinder 146 is installed on the frame above the roller and is used to measure the height of the roller 145. Figure 13 As shown, the height of the roller 145 is controlled by the fixed-distance servo motor 141, so the distance from the punching position 1001 of the punching knife 131 to the first cross-cutting position 1002 can be controlled by the height of the roller 145. This allows the punching action and the first cross-cutting action to be performed simultaneously, improving the speed of the equipment.

[0062] The single-stage cross-cutting mechanism 16 includes a fixed frame 161, a cross-cutting drive cylinder 162, a lower guillotine 163, an upper guillotine 164, a film pressing cylinder I 165, and a film pressing plate I 166. The fixed ends of the cross-cutting drive cylinder 162 and the film pressing cylinder I 165 are both mounted on the fixed frame 161. The two ends of the lower guillotine 163 are fixedly connected to the fixed frame 161. The upper guillotine 164 is mounted on the movable end of the cross-cutting drive cylinder 162. The cross-cutting drive cylinder 162 drives the upper guillotine 164 to move up and down. When the upper guillotine 164 moves downward, it forms a scissor structure with the lower guillotine 163 to complete the film cutting. The film pressing plate I 166 is mounted on the movable end of the film pressing cylinder I 165. The film pressing cylinder I 165 drives the film pressing plate I 166 to move up and down. Meanwhile, before cutting, the pressure cylinder I165 drives the pressure plate I166 to move downwards, completing the auxiliary action for cutting, so that the film is flat and then a cross-cut is performed.

[0063] The transverse conveying mechanism 17 includes a first conveying line 171, a centering and straightening mechanism 172, a blocking mechanism 173, and a hand-operated passageway 174. The blocking mechanism 173 is arranged in the running direction of the first conveying line 171. The centering and straightening mechanism 172 is arranged on both sides of the first conveying line 171 to straighten the glass on the first conveying line 171. The hand-operated passageway 174 is arranged in front of the transverse conveying mechanism 17 and is used to connect to the cross-cutting machine 5.

[0064] The blocking mechanism 173 includes a lifting cylinder II 1731 and a blocking wheel II 1732. When the glass reaches the blocking mechanism 173, the lifting cylinder II 1731 lifts the blocking wheel II 1732, blocking the glass and stopping its movement. Then, the centering and straightening mechanisms 172 on both sides of the first conveyor line 171 begin to work.

[0065] The centering and straightening mechanism 172 includes a servo motor 1721, a linear guide rail III 1722, a synchronous belt III 1723, a lifting cylinder I 1724, and a blocking wheel I 1725. Two sets of lifting cylinders I 1724 are respectively arranged on the left and right sides of the conveyor line. The lifting cylinders I 1724 and the linear guide rail III 1722 are slidably connected. The two sets of lifting cylinders I 1724 are respectively fixed on both sides of the synchronous belt III 1723. When the servo motor 1721 rotates, the lifting cylinders I 1724 on both sides are driven to move simultaneously towards the center line of the first conveyor line 171. At the same time, the lifting cylinders I 1724 raise the blocking wheel I 1725, thus clamping the glass by the blocking wheels I 1725 on both sides, achieving the centering and straightening action of the glass.

[0066] Specifically, a blocking mechanism 173 is arranged in the running direction of the first conveyor line 171. When the glass reaches the blocking mechanism 173, it is blocked and the conveying stops. Then, the centering and straightening mechanisms 172 on both sides straighten the glass, and then the film-pulling mechanism 300 performs the film-laying action. A 500mm gap is left between the high-speed edge cutter 1 and the straightening cross-cutting machine 5 so that the staff can stand between the two machines when the equipment is being maintained. Therefore, a hand-operated passageway 174 is arranged in front of the transverse conveyor 17 for connecting to the next machine, the straightening cross-cutting machine 5. This mechanism is in the extended state when the equipment is running normally. When the equipment is being maintained, this mechanism is manually retracted to facilitate the personnel to enter between the two machines.

[0067] The cross-cutting machine 5 consists of a cross-cutting conveying mechanism 51, a leveling mechanism 52, a secondary cross-cutting mechanism 53, and a lifting suction cup mechanism 54.

[0068] The alignment conveying mechanism 51 includes a second conveyor line 511, a servo shifting mechanism 512, and a pneumatic shifting mechanism 513. Two sets of servo shifting mechanisms 512 are arranged in front of and to the left of the second conveyor line 511 in its running direction, and two sets of pneumatic shifting mechanisms 513 are arranged behind and to the right of the second conveyor line 511 in its running direction. Glass from the high-speed edge cutting machine 1 is connected to the alignment cross-cutting machine 5 via the second conveyor line 511. The servo shifting mechanism 512 uses a servo motor for shifting, and the pneumatic shifting mechanism 513 uses a pneumatic cylinder for shifting.

[0069] The leveling mechanism 52 includes a leveling drive servo motor 521, a synchronous belt II 522, a film pressing module 523, a leveling module 524, a profile frame 525, and a linear guide rail II 526. The linear guide rail II 526 is mounted on the profile frame 525. The film pressing module 523 and the leveling module 524 are respectively arranged on both sides of the profile frame 525. The leveling drive servo motor 521 drives the synchronous belt II 522 to move, and the synchronous belt II 522 drives the leveling module 524 to move towards the center along the linear guide rail II 526.

The vision camera 535 is placed next to the secondary cross-cutting blade 534 to detect the offset position of the film from the glass. The receiving box 536 is arranged below the secondary cross-cutting blade 534 to collect the waste material after the secondary cross-cutting.

[0071] Specifically, depending on the size of the film, the cutter shifting servo motor 533 drives the secondary cross-cutting blade 534 to move along the guide rail 532 and the rack 531 to the accurate position, and then the secondary cross-cutting blade 534 performs a secondary cut on the film, such as... Figure 14 As shown, the secondary cutting position is the secondary horizontal cutting position 1004.

[0073] Meanwhile, an electrostatic generator 55 is installed at the outlet of the cross-cutting machine 5. When the glass that has completed the cross-cutting operation flows out from the second conveyor line 511, the electrostatic generator 55 works and emits electrostatic ions on the glass and the film on the glass, so that the film is tightly adsorbed on the glass and will not slip on the subsequent production line, thus ensuring product quality.

[0074] The present invention also relates to a method of using a film cutting and laying device, wherein the method of using the aforementioned film cutting and laying device is as follows:

[0075] S1. The film from the feeding mechanism 100 passes sequentially through the lifting buffer mechanism 11, the edge cutting mechanism 12, the punching mechanism 13, the spacing mechanism 14, the discharge mechanism 15, and the first transverse cutting mechanism 16. The film is pulled out by the film pulling mechanism 300 and laid on the glass that has been positioned in the transverse conveying mechanism 17. The film is edge-cut during the film pulling process. The edge cutting knife group 122 can move to any position on the shifting guide rail 121. The edge cutting knife group 122 and the edge cutting bottom knife 123 form a scissor structure to cut the edge material of the passing film. The two longitudinal edge cutting positions 1003 of the film are cut when passing through the edge cutting mechanism 12.

[0076] S2. The height of the roller 145 is controlled by the fixed-distance servo motor 141, so the distance from the punching position 1001 of the punching knife 131 to the first cross-cutting position 1002 can be controlled by the height of the roller 145, so that the punching action and the first cross-cutting action can be performed simultaneously, thereby improving the speed of the equipment.

[0077] S3. Before cutting, the pressure cylinder I165 drives the pressure plate I166 to move downward to complete the auxiliary action of cutting, so that the film is flat and then cross-cutting is performed again; when the upper guillotine 164 moves downward, it forms a scissor structure with the lower guillotine 163 to complete the cutting of the film, that is, the first cross-cut position 1002, cutting the roll into a sheet.

[0078] S4. After one cross-cutting operation is completed, the film is first laid on the glass on the first conveyor line 171, and then conveyed by the first conveyor line 171 to the second conveyor line 511 of the cross-cutting machine 5.

[0079] S5. The glass is first positioned by the four-sided shifting mechanism on the second conveyor line (511), and then the vision camera takes a picture. After the picture is taken, the film on the glass is sucked up by the suction cup frame above and lifted to the highest position. At the same time, the industrial control computer starts to calculate the correction position according to the picture result. The calculation result is sent to the PLC controller, and then the PLC controller controls the four-sided shifting mechanism of the glass to reposition the glass. The film on the glass being sucked up by the suction cup frame above is equivalent to the position of the film being fixed. After the shifting mechanism repositions the glass, the relative position of the glass and the film is calibrated.

[0080] The correction system is programmed using a PLC controller. Specifically, the film on the glass is held in place by the suction cup above, which means the position of the film is fixed. The PLC controller controls the movement of the servo shifting mechanism to correct the position of the glass.

[0081] S6. The suction cup holder lowers the film to the secondary cross-cutting position 1004 for secondary cutting, and the waste material falls into the receiving box 536;

[0082] S7. The suction cup holder continues to descend, and then the film is applied to the glass that has been positioned and corrected.

[0083] S8. The leveling mechanism starts to operate. First, the film pressing module presses the film, and then the leveling module performs a leveling action to eliminate the bulges that occur after the film is applied to the glass.

[0084] S9. The second conveyor line will discharge the laid glass, and at the same time, the electrostatic generator above the cross-cutting machine will activate to emit electrostatic ions onto the film and glass, so that the film is tightly adsorbed onto the glass.

[0085] This invention eliminates the material transfer action of the transfer robot, and the film is directly applied to the glass. Then, the precise position is obtained through correction. The electrostatic generator can emit electrostatic ions to the glass and the film on the glass, so that the film is tightly adsorbed on the glass and will not slip on the subsequent production line, thus ensuring product quality.

[0086] This invention completes the edge cutting on both sides on a rough cutting machine. Then, because the film will deform due to the stretching action in the length direction, a second cutting is performed on the next machine to obtain the correct film size. In addition, a leveling mechanism is added to solve the bulging problem. Traditional fine cutting machines have a slow cycle time and a large footprint. This technical solution improves the cycle time, reduces the footprint, and lowers the cost.
