Description

Technical Field

[0001] This application relates to the field of EVA film processing equipment technology, and in particular to photovoltaic module EVA film cutting and laying equipment. Background Technology

[0002] In the production and processing of photovoltaic modules, EVA film is an important encapsulation material, requiring a series of processing operations such as cutting, punching round holes, and laying. Existing photovoltaic module EVA film cutting and laying equipment mostly uses screws to press the EVA roll's mounting shaft, requiring the use of wrenches or disassembly tools. This is inconvenient, results in poor fixation, and easily leads to shaft misalignment and inconsistent heights at both ends, causing the EVA film to shift and wrinkle during transport. Furthermore, the guide structure during EVA film transport has a fixed position, making it impossible to flexibly adjust according to different EVA film specifications. Adjusting the transport height is also cumbersome, resulting in low overall equipment ease of operation and impacting the processing efficiency and quality of photovoltaic module EVA film. Summary of the Invention

[0003] To improve the ease of operation of photovoltaic module EVA film cutting and laying equipment, this application provides photovoltaic module EVA film cutting and laying equipment.

[0004] This application provides photovoltaic module EVA film cutting and laying equipment, which adopts the following technical solution: A photovoltaic module EVA film cutting and laying equipment includes a frame, on which a punching mechanism, a rolling and feeding mechanism, and a bidirectional cutting mechanism are mounted. A mounting shaft for mounting EVA rolls is detachably mounted on the frame. A positioning plate for placing the mounting shaft is mounted on the frame, and the positioning plate has a locking slot. A fixing assembly for fixing the mounting shaft is mounted on the frame. A guide assembly for guiding the movement of the EVA film is mounted on the frame. An adjustment assembly for pressing the EVA film and adjusting the EVA film conveying height is mounted on the frame.

[0005] By adopting the above technical solution, the EVA roll is installed on the mounting shaft, and then the mounting shaft is placed in the bayonet of the positioning plate for initial positioning. The mounting shaft is firmly fixed by the fixing component to prevent it from shifting during rotation. The guide component guides the conveying direction of the EVA film to prevent the EVA film from shifting during conveying. The conveying height of the EVA film can be flexibly adjusted by adjusting the component to adapt to the height requirements of different processing steps. The components work together to achieve stable conveying and processing of EVA film. Moreover, the operation of mounting shaft assembly / disassembly, guide position adjustment, and conveying height adjustment is simple and quick, effectively improving the ease of operation of the equipment.

[0006] In one specific implementation scheme, the mounting shaft includes an air shaft, both ends of which are rotatably mounted with pulleys. The pulleys have slots. One end of the air shaft is connected to a first gear. A second gear is rotatably mounted on the frame. A motor is mounted on the frame. The output shaft of the motor is connected to the second gear via a synchronous pulley and synchronous belt.

[0007] By adopting the above technical solution, the air shaft can be tightened and fixed according to the inner diameter of the EVA roll, adapting to different specifications of EVA rolls and having strong applicability; the pulley slot cooperates with the positioning plate, which facilitates the placement and initial positioning of the installation shaft; the motor drives the second gear to rotate through the synchronous pulley and synchronous belt, and then drives the air shaft to rotate through the meshing first gear, realizing the automatic conveying of EVA film, reducing the intensity of manual operation, improving the conveying efficiency, and the high stability of the gear meshing transmission, ensuring the uniformity of EVA film conveying.

[0008] In one specific implementation, the fixing component includes a lifting plate that is slidably mounted on the positioning plate. A first cylinder is mounted on the frame, and the output shaft of the first cylinder is connected to a first connecting plate. The first connecting plate is connected to the lifting plate, and a push block is mounted on the lifting plate. The side of the push block near the bayonet is cut with a bevel.

[0009] By adopting the above technical solution, the first cylinder drives the first connecting plate to lift the lifting plate, which in turn drives the push block to move. The inclined surface of the push block contacts the pulley of the mounting shaft. Through the pushing force of the inclined surface, the pulley can be gradually pressed against the slot of the positioning plate, realizing the automatic clamping and fixing of the mounting shaft. No manual tightening is required, making the operation convenient. Moreover, the inclined surface contact method makes the clamping process stable and avoids hard impact damage to the pulley.

[0010] In one specific implementation scheme, a slide rod is mounted on the positioning plate, a telescopic sleeve is slidably mounted on the slide rod, a movable plate is mounted on the telescopic sleeve, a first spring is sleeved on the slide rod, a guide rod is mounted on the positioning plate, a pressure block is slidably mounted on the guide rod, a second spring is sleeved on the guide rod, a first pull block is mounted on the pressure block, a second connecting plate is mounted on the movable plate, a second pull block is mounted on the second connecting plate, the first pull block and the second pull block abut against each other, and the surfaces of the first pull block and the second pull block that abut against each other are both formed into convex arc-shaped surfaces.

[0011] By adopting the above technical solution, the pulley contacts the movable plate under the push of the push block and squeezes the movable plate to move. The movable plate drives the second pull block to move through the second connecting plate. The second pull block abuts against the first pull block through the arc surface and pushes the first pull block to drive the pressure block to move downward along the guide rod. The pressure block can press on the pulley, so that the pulley is always in close contact with the positioning plate, effectively preventing the installation shaft from having inconsistent heights at both ends during the extrusion process, ensuring the horizontality of the installation shaft, and thus ensuring the uniformity of EVA film delivery. The first spring and the second spring can realize the automatic reset of the movable plate and the pressure block, which facilitates the disassembly of the installation shaft. The arc surface makes the contact transmission between the second pull block and the first pull block smoother and avoids jamming.

[0012] In one specific implementation, the bottom surface of the pressure block is formed as a concave arc shape.

[0013] By adopting the above technical solution, the bottom surface of the arc-shaped pressure block is adapted to the arc-shaped outer circumference of the pulley, increasing the contact area between the pressure block and the pulley, making the pressing more close and stable, further improving the limiting effect on the pulley, and preventing the pulley from wobbling up and down during rotation.

[0014] In one specific implementation, a first gasket is installed on the push block, a second gasket is installed on the movable plate, and a third gasket is installed on the pressure block.

[0015] By adopting the above technical solution, the first, second, and third gaskets are all made of elastic and wear-resistant materials, which can effectively buffer the contact impact between the push block, movable plate, pressure block, and pulley, reduce the wear of the parts, and extend the service life. At the same time, the elastic gaskets can increase the contact friction and improve the fixing and limiting effect.

[0016] In one specific implementation, the guide assembly includes a fixed rod mounted on the positioning plate, an adjusting plate mounted on the fixed rod, and a guide rod mounted on the adjusting plate.

[0017] By adopting the above technical solution, the guide rod plays a guiding and limiting role in the EVA film during the conveying process, preventing the EVA film from shifting to both sides during conveying, ensuring that the EVA film is conveyed in the predetermined direction, and providing a precise feeding basis for subsequent processing steps such as cutting and punching round holes.

[0018] In one specific implementation, the adjusting plate is provided with a sliding groove, and a slider is slidably mounted on the adjusting plate through the sliding groove. The sliding groove is a T-shaped groove, and the slider is a T-shaped block. The guide rod is mounted on the slider. The adjusting plate is provided with a row of insertion holes, and the slider is also provided with holes. A locking plug is inserted into the adjusting plate through the insertion holes, and the slider is fixed on the adjusting plate through the locking plug.

[0019] By adopting the above technical solution, the cooperation between the T-shaped groove and the T-shaped slider allows the slider to slide smoothly along the adjustment plate, thereby driving the guide rod to adjust its position, adapting to the guiding requirements of EVA films of different widths and specifications, and has strong applicability; after the adjustment is completed, the locking plug is inserted into the plug hole of the adjustment plate and the hole of the slider to fix the slider, which is precise in positioning. The method of disassembling and assembling the locking plug makes the position adjustment operation of the guide rod simple and quick.

[0020] In one specific implementation, the adjustment assembly includes a rocker arm, one end of which is hinged to the frame and the other end of which is rotatably mounted with a roller. A second cylinder is hinged to the frame, and the output shaft of the second cylinder is hinged to the middle position of the rocker arm.

[0021] By adopting the above technical solution, the extension and retraction of the output shaft of the second cylinder can drive the rocker arm to swing around the hinge point, thereby driving the roller to rise and fall. The roller presses on the EVA film. The conveying height of the EVA film can be flexibly adjusted by the swing of the rocker arm, which can adapt to the height requirements of different processing mechanisms such as punching round holes and bidirectional cutting mechanisms. Moreover, the cylinder-driven method has high adjustment accuracy and is easy to operate. The roller and the EVA film roll in contact, which can reduce the wear on the surface of the EVA film.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application achieves quick assembly and disassembly and secure fixation of the mounting shaft through the cooperation of positioning plate, bayonet and fixing components, effectively preventing the mounting shaft from shifting and the height of the two ends from being inconsistent, ensuring the uniformity of EVA film conveying. At the same time, the guide component can flexibly adjust the guide position to adapt to different specifications of EVA film, and the adjustment component can conveniently adjust the EVA film conveying height. The synergistic effect of each component greatly improves the ease of operation and applicability of the equipment. 2. By setting elastic pads on the push block, movable plate and pressure block, the contact impact between the parts is buffered, wear is reduced and the service life of the equipment is extended. At the same time, the contact friction is increased and the fixing and limiting effect is improved. The bottom surface of the pressure block is set as an inward arc shape to match the outer circumference of the pulley, so that the pressing is more stable and the horizontality of the installation shaft is further guaranteed.

[0023] 3. This application uses a motor and gear meshing transmission to drive the installation shaft to automatically transport the EVA film, reducing the intensity of manual operation and improving the transport efficiency. The gear transmission and rolling conveying method ensures the uniformity and stability of the EVA film transport, effectively avoiding wrinkles and displacement of the EVA film and improving the processing quality of the EVA film for photovoltaic modules.

[0036] The EVA roll is threaded onto the air shaft 22, which is then placed on the positioning plate 11. The slot 211 on the pulley 21 is then engaged with the positioning plate 11. The EVA roll is pushed to move the pulley 21 into the slot 111, and at the same time, the first gear 23 and the second gear 12 are engaged.

[0037] Reference Figure 4 and Figure 5 The fixing component 3 includes a lifting plate 31, which is slidably mounted on the positioning plate 11. A first cylinder 33 is fixedly mounted on the frame 1. The output shaft of the first cylinder 33 is vertically downward and fixedly connected to a first connecting plate 331. The first connecting plate 331 is fixedly connected to the lifting plate 31. A push block 32 is fixedly mounted on the top surface of the lifting plate 31. The side of the push block 32 near the bayonet 111 has a beveled surface 321, and a first gasket 322 is fixedly mounted on the beveled surface 321.

[0038] After the EVA roll is placed, the first cylinder 33 controls the first connecting plate 331 and the lifting plate 31 to move. The lifting plate 31 rises, and the lifting plate 31 drives the push block 32 to rise. The inclined surface 321 on the push block 32 will contact the pulley 21. Through the action of the inclined surface, the push block 32 will gradually push the pulley 21 so that the pulley 21 is pressed against the slot 111 on the positioning plate 11.

[0039] A sliding rod 341 is fixedly installed on the positioning plate 11. A telescopic sleeve 342 is slidably installed on the sliding rod 341. A movable plate 343 is fixedly installed on the telescopic sleeve 342. A first spring 344 is sleeved on the sliding rod 341. One end of the first spring 344 is fixedly connected to the positioning plate 11, and the other end is fixedly connected to the movable plate 343. A second washer 345 is fixedly installed on the movable plate 343. A guide rod 351 is fixedly installed on the positioning plate 11. A pressure block 353 is slidably installed on the guide rod 351. A second spring 352 is sleeved on the guide rod 351.

The first pull block 354 and the second pull block 356 abut against each other, and the abutting surfaces of the first pull block 354 and the second pull block 356 are both opened into convex arc surfaces.

[0040] The first gasket 322, the second gasket 345, and the third gasket 357 are all made of wear-resistant rubber.

[0041] When pulley 21 moves to contact the second pad 345, pulley 21 will press the movable plate 343 to move. The movable plate 343 will drive the second connecting plate 355 to move. The second connecting plate 355 will drive the second pull block 356 to move. The second pull block 356 will contact the first pull block 354. Through the action of the arc surface, the second pull block 356 will push the first pull block 354 and the pressure block 353 to move downward. The pressure block 353 will move downward and press on the pulley 21, so that the lower end of the pulley 21 is always in contact with the positioning plate 11. Through the pressing of the pressure block 353, it can effectively prevent the two ends of the mounting shaft 2 from being uneven in height under the squeezing of the push block 32, with one side higher and the other lower, thereby ensuring that the EVA film is rolled up evenly.

[0042] Reference Figure 4 , Figure 6 and Figure 7 The guide assembly 4 includes a fixed rod 41, which is fixedly mounted on the positioning plate 11. An adjusting plate 42 is fixedly mounted on the fixed rod 41. The adjusting plate 42 has a sliding groove 421, through which a slider 43 is slidably mounted. The sliding groove 421 is a T-shaped groove, and the slider 43 is a T-shaped block. A guide rod 44 is fixedly mounted on the slider 43. The adjusting plate 42 has a row of insertion holes 422, and the slider 43 also has holes. Locking inserts 45 are inserted into the adjusting plate 42 through the insertion holes 422, and the slider 43 is fixed to the adjusting plate 42 through the locking inserts 45.

[0043] Reference Figure 2 and Figure 4 The adjustment assembly 5 includes a rocker arm 51, one end of which is hinged to the frame 1, and the other end is rotatably mounted with a roller 52. A second cylinder 53 is hinged to the frame 1, and the output shaft of the second cylinder 53 is hinged to the middle position of the rocker arm 51.

[0044] The implementation principle of this application embodiment is as follows: First, the EVA roll is threaded onto the air expansion shaft 22, and the air expansion shaft 22 is inflated to achieve tension and fixation. Then, the mounting shaft 2 is placed on the positioning plate 11, so that the slot 211 of the pulley 21 cooperates with the positioning plate 11, and the first gear 23 meshes with the second gear 12 to complete the initial positioning of the mounting shaft 2. The first cylinder 33 is activated to drive the push block 32 to rise, and the pulley 21 is pressed against the slot 111 through the inclined surface 321. At the same time, the pulley 21 squeezes the movable plate 343 to move, driving the pressure block 353 to press down on the pulley 21, ensuring the horizontality and fixed stability of the mounting shaft 2.

[0045] According to the width specifications of the EVA film, pull out the locking plug 45, slide the slider 43 to adjust the spacing of the guide rod 44, and then insert the locking plug 45 to complete the fixation; start the second cylinder 53, and drive the roller 52 to rise and fall through the swing rod 51 to adjust the conveying height of the EVA film to the appropriate position. Start the motor 13, and the motor 13 drives the second gear 12 to rotate through the synchronous pulley and synchronous belt, which in turn drives the air shaft 22 to rotate through the first gear 23, realizing the automatic conveying of the EVA film. After being guided by the guide rod 44 and pressed by the roller 52, the EVA film is sequentially conveyed to the punching mechanism, the bidirectional cutting mechanism and the rolling discharge mechanism to complete a series of processing operations such as punching, cutting, laying and discharge.

[0046] When it is necessary to replace the EVA roll, turn off the motor 13 and the first cylinder 33. The first cylinder 33 drives the push block 32 to descend. The movable plate 343 and the pressure block 353 release the limit on the pulley 21 under the action of the spring reset. The mounting shaft 2 can be directly removed from the bayonet 111, which is convenient for disassembly and assembly.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
