A positioner cylinder 35 is installed on the receiving plate 34. A long-side positioner 36 is connected to the telescopic shaft of the positioner cylinder 35. The long-side positioner 36 includes a first long-side positioner 50, a second long-side positioner 51, a third long-side positioner 52, and a fourth long-side positioner 53, arranged in a rectangular pattern. Both the short-side positioner 27 and the long-side positioner 36 employ photoelectric sensors. The photovoltaic transmission component 146 is used to receive, transport, and position the glass plate 58 carrying the photovoltaic cell string.

[0035] Specifically, the glass plate 58 carrying the photovoltaic cell string is inserted into the conveyor 11 and placed onto the conveyor belt 15. The conveyor motor 16 starts, driving the drive shaft 17 to rotate. The drive shaft 17 drives the synchronous pulley connected to it to rotate, causing the conveyor belt 15 to run. The bottom surface of the glass plate 58 abuts against the guide roller 20, which supports the glass plate 58 and prevents increased friction by rotating the guide roller 20. The conveyor belt 15 pulls the glass plate 58 into the equipment housing 10. The long side positioner 36 detects the position of the long side of the glass plate 58. After the glass plate 58 is positioned between the two long side positioners 36, the conveyor motor 16 stops, stopping the conveyor belt 15. Then, the short side positioner 27 detects the position of the short side of the glass plate 58 and controls the longitudinal drive motor 30 to start. When the motor 30 starts, it drives the synchronous belt of the first synchronous belt group 23 to rotate, causing the two transverse connecting plates 24 on both sides to move the two short side positioning frame plates 25 closer to each other until the short side positioner 27 detects the short side of the glass plate 58. By starting the longitudinal drive motor 30, the longitudinal connecting shaft 31 is driven to rotate. The rotation of the longitudinal connecting shaft 31 can drive the synchronous belt on the second synchronous belt group 32 to rotate, thereby causing the longitudinal connecting plates 34 on both sides of the synchronous belt of the second synchronous belt group 32 to move closer or further apart, thereby adjusting the spacing of the long side positioner 36. In conjunction with the transverse drive motor 22 to adjust the spacing of the short side positioner 27, it can adapt to the positioning adjustment of glass plates 58 of different lengths and widths, forming a short side positioning mechanism and a long side positioning mechanism for respectively positioning and correcting the long and short sides of the glass plate 58.

[0036] like Figure 2 and Figure 5As shown, the main body of the equipment includes two sets of crossbeams, which are connected to the equipment housing 10 in a front-to-back manner and located above the photovoltaic transmission module 146. Each set of crossbeams consists of several units arranged horizontally. Several sets of battery string picking and placing components 147 are arranged horizontally on the crossbeams. Each battery string picking and placing component 147 includes a picking and placing beam 59 connected to the crossbeam. An active lifting frame 60 is provided on one side of the picking and placing beam 59, and a driven lifting frame 62 is provided on both the front and rear sides of the active lifting frame 60 on the same side of the picking and placing beam 59. Three third guide rail groups 61 are connected to the side of the picking and placing beam 59. Each third guide rail group 61 includes a guide rail and a slide block slidably connected to the guide rail. The slide blocks of the three third guide rail groups 61 are respectively connected to the active lifting frame 60 and the driven lifting frame 62. A lifting drive motor 63 is installed on the pick-up and drop beam 59. A lifting gear 64 is connected to the rotating shaft of the lifting drive motor 63. A lifting rack 65 is connected to the side of the active lifting frame 60. The lifting gear 64 meshes with the lifting rack 65. A series frame 66 is connected to the bottom surface of the active lifting frame 60 and the driven lifting frame 62. The active lifting frame 60 and the driven lifting frame 62 are connected to the series frame 66. Several connecting frames 67 are connected to the series frame 66. The several connecting frames 67 are distributed left and right and are arranged longitudinally. The connecting frames 67 are connected to a suction cup frame 68 arranged longitudinally. Several suction cups 69 are connected to the bottom surface of the suction cup frame 68. Several air connectors are connected to the top surface of the suction cup frame 68. The air connectors on the top surface of the suction cup frame 68 are used to connect with the suction cups 69.

[0037] Specifically, after the glass plate 58 is positioned, the lifting drive motor 63 drives the lifting gear 64 to rotate, which in turn drives the active lifting frame 60 to descend through meshing with the lifting rack 65. When the active lifting frame 60 descends, it drives the third guide rail group 61, the driven lifting frame 62, the series frame 66, and the connecting frame 67 to descend together, so that the suction cup 69 comes into contact with the battery string. After negative pressure is applied to the suction cup 69, the suction cup 69 adsorbs the battery string. Then, the lifting drive motor 63 drives the lifting gear 64 to rotate in the opposite direction, which in turn causes the active lifting frame 60 to rise, lifting the battery string from the glass plate 58. Then, the transfer structure on the crossbeam drives the battery string to move laterally until it reaches the film application position. After the film application is completed, the transfer structure in the crossbeam resets the pick-and-place beam 59, controls the active lifting frame 60 to descend again, and resets the battery string onto the glass plate 58. Then, positive pressure is applied to the suction cup 69 to release the adsorption of the battery string. Finally, the lifting drive motor 63 drives the active lifting frame 60 to rise and reset.

[0038] like Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, the main body of the equipment includes a membrane strip feeding assembly 148. There are three sets of membrane strip feeding assemblies 148, distributed from left to right relative to the photovoltaic transmission assembly 146. Each membrane strip feeding assembly 148 includes a storage beam 70, which is installed on the inner wall of the equipment housing 10. Storage vertical beams 71 are connected to the front and rear ends of the bottom side of the storage beam 70. A tray frame 72 is connected to the side wall of the storage vertical beam 71. A tray connecting frame 73 is connected to the inner side of the tray frame 72. A tray fixing frame 74 is connected to the tray connecting frame 73. A membrane strip cylinder 75 is rotatably mounted on the side of the tray fixing frame 74. The membrane strip cylinder 75 is used to wind several turns of the membrane strip 107. A buffer drive motor 76 is installed on the tray fixing frame 74. The rotating shaft of the buffer drive motor 76 is connected to the membrane strip cylinder 75. The storage vertical beam 70... 1. Guide rods 77 are connected to both the upper and lower ends. A slider 78 is slidably connected to the guide rods 77. The slider 78 is connected to the storage vertical beam 71. A first idler wheel 79 is rotatably mounted on the front of the guide rods 77. A second idler wheel 80 is rotatably mounted on the middle of the side of the storage vertical beam 71. A first guide wheel 81 is rotatably mounted on the top of the side of the storage vertical beam 71. Several U-shaped groove sensors 82 are installed from top to bottom on the side of the storage vertical beam 71 away from the membrane strip cylinder 75. The above structure constitutes the membrane strip feeding mechanism. Cutting frames 83 are provided at both the front and rear ends above the storage crossbeam 70 inside the equipment housing 10. The cutting frame 83 has an opening on its side for the membrane strip 107 to pass through. A second guide wheel 84 is rotatably mounted on one side of the cutting frame 83. Appropriate openings are provided on both the first guide wheel 81 and the second guide wheel 84. The annular groove of the film strip 107 is fitted with a cutting frame 83. A pressure cylinder 86 is installed on one side of the cutting frame 83 corresponding to the second guide wheel 84. A pressure plate 87 is connected to the telescopic shaft of the pressure cylinder 86. A pair of opposing clamping wheels 85 are rotatably arranged between the second guide wheel 84 and the pressure plate 87 on one side of the cutting frame 83. A pair of opposing cutting cylinders 88 are installed on the side of the cutting frame 83 away from the pressure plate 87. A cutting blade 89 is connected to the telescopic shaft of the cutting cylinder 88 through a blade holder. The above structure constitutes the film strip cutting mechanism. Inside the equipment housing 10, a film strip pulling frame 90 is arranged between the two cutting frames 83. Several guide plates 91 are arranged and connected on the surface of the film strip pulling frame 90. Several rotating holes are opened on the guide plates 91 in opposite directions, and one pair of rotating holes are rotated inward. The device is connected by double-sided guide posts 92. Two guide plates 91 on the front and rear sides pass through two cutting frames 83 and are located below the pressure plate 87. The film strip pulling frame 90 is connected to a guide rail on its side. Two slide blocks are slidably connected to the guide rail. A pulling motor frame 93 is connected to the slide blocks. A pulling motor 94 is installed on the pulling motor frame 93. The drive shaft of the pulling motor 94 is downward and connected to a pulling gear 95. A pulling rack 96 is connected to the top surface of the storage beam 70. The pulling gear 95 meshes with the pulling rack 96. A pulling chuck 97 driven by a cylinder is installed on the pulling motor frame 93. The pulling chuck 97 corresponds between a pair of double-sided guide posts 92. A flattening frame 98 is set above the film strip pulling frame 90 inside the equipment housing 10. A fourth guide rail group 99 is connected to the flattening frame 98.The fourth guide rail assembly 99 includes guide rails and two slide blocks slidably connected to the guide rails. A flattening motor frame 100 is connected to the slide blocks of the fourth guide rail assembly 99. A flattening motor 101 is mounted on the flattening motor frame 100. The drive shaft of the flattening motor 101 is downward and connected to a flattening gear 102. A flattening rack 103 is connected to the flattening frame 98. The flattening gear 102 meshes with the flattening rack 103. A first flattening cylinder 104 is mounted on the bottom side of the flattening motor frame 100. A second flattening cylinder 105 is mounted on the telescopic shaft of the first flattening cylinder 104. A pressure head 106 is connected to the telescopic shaft of the second flattening cylinder 105. The pressure head 106 corresponds between a pair of double-sided guide pillars 92. The above structure constitutes a membrane strip pulling mechanism.

[0039] Specifically, after one end of the membrane strip 107 wound on the membrane strip cylinder 75 is pulled out, it passes through the groove of the U-shaped groove sensor 82 and then alternately adheres to the first idler wheel 79, the second idler wheel 80, the first guide wheel 81, and the second guide wheel 84. This provides sufficient buffer length for feeding the membrane strip 107. The U-shaped groove sensor 82 is used to detect whether the buffer length needs to be released. The annular grooves on the first guide wheel 81 and the second guide wheel 84 are used to guide and correct the deviation of the membrane strip 107. Then, one end of the membrane strip 107 passes through a pair of clamping wheels 8. After passing through the opening of the cutting frame 83, the film strip 107 is placed on the guide plate 91. The double-sided guide posts 92 clamp both sides of the film strip 107 for further correction. The traction chuck 97 is driven by the cylinder to press down and clamp the film strip 107. During traction, the buffer drive motor 76 starts to drive the film strip cylinder 75 to rotate and release the material. The traction motor 94 starts to rotate the traction gear 95. The traction gear 95 drives the traction motor frame 93 to move through the meshing with the traction rack 96. When the traction motor frame 93 moves, it clamps the film strip 107 through the traction chuck 97. The clamp at one end pulls the film strip 107 onto the guide plate 91. After the U-shaped groove sensor 82 detects that the material has been fed to the set length, the buffer drive motor 76 and the traction motor 94 stop. The pressing cylinder 86 pushes the pressing plate 87 down to press and fix the film strip 107. The telescopic shaft of the cutting cylinder 88 extends to allow the cutting blade 89 to cut the film strip 107. After cutting, the cutting blade 89 resets, the pressing plate 87 resets and releases the film strip 107, and the traction motor 94 continues to start to pull the film strip 107 to the feeding position, and then stops, completing the first flattening. Cylinder 104 and the second flattening cylinder 105 extend in succession, allowing the pressing head 106 to apply pressure to the other end of the film strip 107. The flattening motor 101 can be started to rotate the flattening gear 102. The position of the pressing head 106 can be adjusted by the meshing of the flattening gear 102 and the flattening rack 103. The cylinder drives the pulling chuck 97 to rise and disengage from the pressure on the film strip 107. The pulling motor 94 starts to rotate the pulling gear 95 in the opposite direction, driving the pulling motor frame 93 to reset, thereby completing the automatic feeding and cutting of the film strip 107.

[0040] like Figure 2 and Figure 9As shown, the main body of the equipment includes a membrane strip transport assembly 149. There are three sets of membrane strip transport assemblies 149, respectively located on the left, center, and right sides within the equipment housing 10. The membrane strip transport assemblies 149 are positioned between the battery string picking and placing assembly 147 and the membrane strip feeding assembly 148. Each membrane strip transport assembly 149 includes a transport fixing beam 108, which is located within the equipment housing 10. There are two transport fixing beams 108, arranged front and back. A first transfer assembly 109 is mounted on each transport fixing beam 108. The first transfer assembly 109 includes components located outside the crossbeam. The system comprises a transfer synchronous belt, a transfer synchronous belt pulley rotatably mounted inside the crossbeam and fitted with the transfer synchronous belt, a transfer motor mounted on the crossbeam, and a transfer drive shaft connected to the rotating shaft of the transfer motor. The drive connection can be achieved by meshing gears at both ends or by another set of synchronous belts. Each end of the transfer drive shaft is connected to two corresponding transfer synchronous belt pulleys at the front and rear positions. Starting the transfer motor causes the transfer drive shaft to rotate, which in turn drives the transfer synchronous belt pulleys, causing the transfer synchronous belt to rotate. This allows the transfer synchronous belt to move the object along the crossbeam. This is existing known technology and will not be described in detail here. A transport moving beam 110 is connected to the transport synchronous belt of the first transfer assembly 109. Three transport fixing plates 111 are connected to the transport moving beam 110. A main lifting plate 114 is provided on the middle transport fixing plate 111, and auxiliary lifting plates 115 are provided on the transport fixing plates 111 at both ends. A fifth guide rail assembly 112 is connected to both the main lifting plate 114 and the auxiliary lifting plates 115. The fifth guide rail assembly 112 includes a guide rail and a slide block slidably connected to the guide rail. The slide block of the fifth guide rail assembly 112 is connected to the corresponding position... The transport fixing plate 111 is connected, and the transport drive motor 113 is installed on the transport fixing plate 111 located in the middle. The rotating shaft of the transport drive motor 113 is connected to a gear (not shown in the figure). The main lifting plate 114 is connected to a rack and meshes with the gear on the transport drive motor 113 (not shown in the figure). The bottom ends of the main lifting plate 114 and the auxiliary lifting plate 115 are connected to a series rod 116. The series rod 116 is connected to a transport suction cup frame 117. The bottom surface of the transport suction cup frame 117 has an opening and a transport suction cup 118 is installed. The side of the transport suction cup frame 117 is provided with an air pipe interface.

[0041] Specifically, after the membrane strip 107 reaches the feeding position, the first transfer component 109 drives the transport moving beam 110 to move towards the feeding position. After reaching the feeding position, the transport drive motor 113 drives the gear to rotate and move the main lifting plate 114 down. The main lifting plate 114 drives the transport suction cup frame 117 down until the transport suction cup 118 contacts the membrane strip 107. Then, the transport suction cup 118 is supplied with negative pressure through the pneumatic conveying system to adsorb the membrane strip 107. The first flattening cylinder 104 and the second flattening cylinder 105 retract in succession to reset the pressure head 106. Then, the rotating shaft of the transport drive motor 113 rotates in the opposite direction to make the main lifting plate 114 rise, which drives the membrane strip 107 adsorbed by the transport suction cup 118 to rise. Then, the first transfer component 109 drives the transport moving beam 110 to move back, completing the transport of the membrane strip 107.

[0042] like Figure 2 and Figure 10 As shown, the main body of the equipment includes a membrane strip heating and correction conveying assembly 150. There are three sets of membrane strip heating and correction conveying assemblies 150, respectively located on the left, center, and right sides of the equipment housing 10. The membrane strip heating and correction conveying assembly 150 is situated between the photovoltaic conveying assembly 146 and the membrane strip feeding assembly 148. Each membrane strip heating and correction conveying assembly 150 includes a heating conveying beam 119, which is located inside the equipment housing 10. A second transfer assembly 120 is installed inside the heating conveying beam 119. The second transfer assembly 120 includes transfer synchronous pulleys rotatably mounted at both ends of the heating conveying beam 119, a transfer synchronous belt sleeved on the synchronous pulleys, and a transfer motor driving the synchronous pulleys to rotate. A sixth guide rail assembly 121 is installed on both the front and rear sides inside the equipment housing 10. The sixth guide rail assembly 121 includes a guide rail and a slide block slidably connected to the guide rail. A heating table 122 is connected to the slide block of the sixth guide rail assembly 121, and the heating table 122 is connected to the transfer synchronous belt of the second transfer assembly 120. A heating platform 122 has an XYR alignment platform on its top surface. Above the XYR alignment platform is a heating platform 123. A wind-blowing assembly 124 is installed on the heating platform 123. The wind-blowing assembly 124 includes a housing, an exhaust port on the housing, and an air pipe interface. The air pipe interface of the wind-blowing assembly 124 is used to connect to a pneumatic conveying system. Exhaust air is discharged through the exhaust port to the XYR alignment platform for cooling, thereby protecting the XYR alignment platform. A heat insulation block 125 is connected to component 124, and a membrane strip carrier 126 is connected to the heat insulation block 125. The membrane strip carrier 126 has negative pressure ports 127 at both ends for connecting to the pneumatic conveying system. The membrane strip carrier 126 has several thermocouple holes 128 for placing thermocouples. The surface of the membrane strip carrier 126 has several small holes communicating with the negative pressure ports 127. The XYR alignment platform can correct the deviation of the membrane strip 107 by adjusting the position of the heating platform 123.

[0043] Specifically, the retracting suction cup frame 117 moves the membrane strip 107 above the membrane strip heating and correction conveying assembly 150, aligning the membrane strip 107 with the heat insulation block 125. Then, the main lifting plate 114 is driven to descend, placing the membrane strip 107 onto the membrane strip carrier 126. Negative pressure is introduced through the negative pressure port 127, causing the small holes on the surface of the suction cup 118 to attract the membrane strip 107. Positive pressure is introduced through the suction cup 118 to lower the membrane strip 107. The membrane strip conveying assembly 149 is reset. When the membrane strip 107 is placed on the membrane strip carrier 126, the thermocouple in the thermocouple hole 128 heats the membrane strip 107. The second transfer assembly 120 moves the heating platform 122 toward the photovoltaic conveying assembly 146, moving the heated membrane strip 107 below the battery string lifted by the battery string pick-and-place assembly 147, and aligning it with the busbar of the battery string.

[0044] like Figure 2 , Figure 11 and Figure 14 As shown, the main body of the equipment includes a membrane strip pasting and pressing assembly 151. There are three sets of membrane strip pasting and pressing assemblies 151, respectively located on the left, center, and right sides within the equipment housing 10. Each membrane strip pasting and pressing assembly 151 includes a pressing moving beam 129. Two pressing moving beams 129 are located within the equipment housing 10 and are distributed front to back. A third transfer assembly 130 is mounted on each pressing moving beam 129. The third transfer assembly 130 has the same structure and function as the first transfer assembly. A pressing and fixing device is connected to the synchronous belt of the third transfer assembly 130. A seventh guide rail assembly 132 is connected to the beam 131, which is a clamping and fixing beam. The seventh guide rail assembly 132 includes a guide rail and a slide block slidably connected to the guide rail. A clamping frame 133 is connected to the slide block of the seventh guide rail assembly 132. A clamping drive motor 134 is installed on the clamping and fixing beam 131. The rotating shaft of the clamping drive motor 134 is connected to a gear (not shown in the figure). A rack (not shown in the figure) is provided on the clamping frame 133 to mesh with the gear on the clamping drive motor 134. Several pressure blocks 135 are connected to the bottom end of the clamping frame 133. The pressure blocks 135 are arranged in a front-to-back distribution.

[0045] Specifically, by controlling the third transfer component 130 to move the clamping and fixing beam 131 above the busbar, after the membrane strip heating and correction conveying component 150 is in place, the battery string picking and placing component 147 drives the battery string to descend until the busbar contacts the membrane strip. The clamping drive motor 134 pushes the clamping frame 133 to descend synchronously through gear transmission, so that the pressure block 135 presses down on the busbar, making the busbar and the membrane strip 107 press and adhere. Then, the clamping drive motor 134 controls the clamping frame 133 to rise, the third transfer component 130 controls the reset, the membrane strip heating and correction conveying component 150 controls the reset, and the battery string picking and placing component 147 controls the battery string and itself to reset.

[0046] like Figure 2 and Figure 12As shown, the main body of the equipment includes a membrane strip visual positioning component 152. There are two membrane strip visual positioning components 152, which are arranged on the left and right sides inside the equipment housing 10. The membrane strip visual positioning components 152 are located above the membrane strip heating and correction conveying component 150. The membrane strip visual positioning component 152 includes a first positioning top beam 136. There are two first positioning top beams 136, which are connected to the inner top wall of the equipment housing 10. The first positioning top beams 136 are connected to a first camera frame 137. The first camera frame 137 is equipped with a plurality of membrane strip positioning cameras 138. The membrane strip positioning cameras 138 are CCD cameras. A light source 139 is also installed below the first camera frame 137.

[0047] Specifically, after the membrane strip transport assembly 149 places the membrane strip 107 onto the membrane strip heating and correction conveying assembly 150, the membrane strip transport assembly 149 is reset. At this time, the membrane strip positioning camera 138 takes a picture to obtain the position of the membrane strip 107 and feeds the result back to the control circuit as a judgment signal for the movement of the membrane strip heating and correction conveying assembly 150, and detects the deviation of the membrane strip on the heating and correction conveying unit from the reference position.

[0048] like Figure 2 and Figure 13 As shown, the main body of the device includes a busbar visual positioning component 153, which is disposed on the inner top wall of the device housing 10. The visual positioning and imaging component includes a second positioning top beam 140, which is connected to the inner top side of the device housing 10. The left and right sides of the bottom side of the second positioning top beam 140 are connected to shooting frames 141. An electric linear module 142 is installed on the bottom side of the shooting frame 141. The sliding part of the electric linear module 142 is connected to a second camera frame 143. A fixed camera frame 144 is connected to the middle of the bottom side of the second positioning top beam 140. Several busbar positioning cameras 145 arranged in a horizontal row are installed on the second camera frame 143 and the fixed camera frame 144. The busbar positioning cameras 145 are CCD cameras.

[0049] Specifically, the position of the busbar is captured by activating the busbar positioning camera 145. The sliding part is moved laterally by activating the electric linear module 142, which drives the second camera frame 143 to adjust its front and rear position, thereby adjusting the shooting position of the second camera frame 143. This detects the deviation of the busbar of the photovoltaic cell string from the reference position and whether the position of the film strip and the busbar after pasting meets the requirements.

[0050] It should be noted that the conveyor frame plate 13, support frame plate 18, short frame plate 21, short side positioning frame plate 25, series frame 66, connecting frame 67, suction cup frame 68, storage crossbeam 70, storage vertical beam 71, disc connecting frame 73, membrane strip pulling frame 90, flattening frame 98, handling moving beam 110, series rod 116, first positioning top beam 136, first camera frame 137, second positioning top beam 140 and shooting frame 141 are all made of industrial aluminum profiles, and the structures on them are all connected by a grooved combination clamp.

[0051] Working principle:

[0052] Before use: Pre-install membrane strip tube 75, manually pull out one end of membrane strip 107, pass it through the groove of U-shaped groove sensor 82, first idler wheel 79, second idler wheel 80, first guide wheel 81, second guide wheel 84, clamping wheel 85 in sequence, and finally pre-place it on guide plate 91.

[0053] In use: First, insert the glass plate 58 carrying the photovoltaic cell string into the conveyor port 11 and place it on the conveyor belt 15. Start the conveyor motor 16 to drive the drive shaft 17 and the synchronous pulley to rotate, so that the conveyor belt 15 can run and send the glass plate 58 into the equipment.

[0054] In the second step, the long side positioner 36 on the longitudinal connecting plate 34 detects the position of the long side of the glass plate 58, the conveying motor 16 stops, the transverse drive motor 22 starts, drives the first synchronous belt group 23, and drives the transverse connecting plate 24 and the short side positioning frame plate 25 to move along the first guide rail group 26 until the short side positioner 27 detects the short side of the glass plate 58.

[0055] In the third step, the lifting drive motor 63 starts, and through the meshing of the lifting gear 64 and the lifting rack 65, it drives the active lifting frame 60 to descend along the third guide rail group 61. The active lifting frame 60 drives the suction cup frame 68 and suction cup 69 to descend through the series frame 66 and the connecting frame 67 until the suction cup 69 contacts and adsorbs the battery string. Then the lifting drive motor 63 reverses and lifts the battery string, thereby providing space for film strip transportation below the photovoltaic cell string.

[0056] In the fourth step, the buffer drive motor 76 starts to release the film strip 107, and the traction motor 94 starts. Through the meshing of the traction gear 95 and the traction rack 96, the traction motor frame 93 is driven to move. The traction chuck 97, driven by the cylinder, clamps one end of the film strip 107 and pulls it. After the U-groove sensor 82 detects that the feeding has reached the set length, the buffer drive motor 76 and the traction motor 94 stop. The pressing cylinder 86 pushes the pressing plate 87 down to fix the film strip 107. The cutting cylinder 88 pushes the cutting blade 89 to cut the film strip. After cutting, the pressing plate 87 and the cutting blade 89 reset. The traction motor 94 continues to work, pulling the film strip 107 to the feeding position. The first flattening cylinder 104 and the second flattening cylinder 105 extend in succession, allowing the pressing head 106 to apply pressure to the other end of the film strip 107 to fix it.

[0057] In the fifth step, the first transfer component 109 drives the transport moving beam 110 to move to the feeding position, the transport drive motor 113 starts, and drives the main lifting plate 114 to descend along the fifth guide rail group 112 through the gear rack, which drives the transport suction cup frame 117 and transport suction cup 118 to descend and adsorb the film strip 107. The first flattening cylinder 104 and the second flattening cylinder 105 on the flattening motor frame 100 retract, the pressure head 106 resets, the transport drive motor 113 reverses, lifts the film strip 107, and the first transfer component 109 transports it to the top of the film strip heating and correction conveying component 150.

[0058] In the sixth step, the transport assembly places the membrane strip 107 on the membrane strip carrier 126. The negative pressure port 127 is used to introduce negative pressure to adsorb and fix the membrane strip. The thermocouple in the thermocouple hole 128 heats the membrane strip 107. The membrane strip positioning camera 138 takes pictures and detects the positional deviation of the membrane strip 107. The data is fed back to the control circuit.
