Description

Technical Field

[0001] This invention relates to the field of cutting machine technology, and in particular to an automatic material receiving device and method for a cutting machine. Background Technology

[0002] Solar module encapsulation is a core technology in the entire module manufacturing industry. During the production process, an adhesive thermosetting film (EVA, Ethylene Vinyl Acetate) 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 the 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, Chinese invention patent CN117410381B discloses an online cutting and laying machine and method for solar EVA. It achieves automatic feeding of the material strip by setting up a feeding structure. However, since the length of the material strip on the roll is fixed, after the material strip on the roll is fed, the head and tail of the new material strip need to be manually fused together using a hot-pressing mechanism. This results in high labor intensity for operators, who need to frequently monitor the remaining material strip and complete the fusion operation as soon as the strip is about to run out, while also managing the loading and unloading of the roll and the roll installation process. Furthermore, the manual fusion process is time-consuming, leading to low material splicing efficiency. Therefore, it is necessary to design a device that can automatically splice the material strip to solve this problem. Summary of the Invention

[0014] The second objective of this invention is to provide an automatic material receiving method for a cutting machine, which has the advantage of enabling automatic material receiving of the material strip, reducing the labor intensity of operators, and improving the efficiency of material receiving.

[0015] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic material receiving method for a cutting machine, employing an automatic material receiving device for a cutting machine as described in any of the above technical solutions; comprising: Step 1: Push the new material roll to the preparation station. The automatic material feeding assembly will automatically transport the new material roll to the feeding station and automatically unload the old material roll. Step 2: Pull out the head of the new material strip and move it to the head clamping and recycling component to achieve initial fixation of the head of the new material strip; Step 3: The tail of the old material strip is clamped and fixed by the tail clamping recycling component. The fusion component connects the head of the new material strip with the tail of the old material strip and heats and fuses them together, thereby automatically connecting the head of the new material strip to the tail of the old material strip. Step 4: The head clamping and recycling assembly and the tail clamping and recycling assembly separate from the fusion joint of the conveyor belt. The residual head and tail of the conveyor belt, which are held by the head clamping and recycling assembly and the tail clamping and recycling assembly, are pulled away from the fusion joint as the conveyor belt is conveyed. Step 5: The head clamping and recycling components and the tail clamping and recycling components loosen the clamping of the residual head and tail, and finally recycle the pulled-out head and tail.

[0016] In summary, the present invention has the following beneficial effects: 1. By setting a support base at the bottom of the alignment seat and installing an automatic belt feeding component for automatic feeding of the belt shaft, the automatic belt feeding component lifts the belt shaft to the preparation position of the support base through a lifting feeding component, and then transfers the belt shaft from the preparation position to the feeding position through a transfer component. The belt is then automatically fed out by a feeding drive component that rotates the belt. Because the support base is inclined downwards along the belt conveying direction and a buffer platform is installed at the end of the support base, the air shaft automatically rolls into the buffer platform due to gravity after the material roll at the feeding position is fed out, achieving automatic unloading. The worker only needs to remove the air shaft from the buffer platform later, without affecting the belt feeding process. The process, thanks to the use of a lifting and feeding assembly, avoids the need for manual lifting of the air shaft carrying the material roll to the preparation position, as in traditional methods. Instead, manual operation is sufficient to roll the air shaft onto the lifting block of the lifting and feeding assembly, significantly reducing labor intensity. Furthermore, by installing a tail clamping and recovery assembly and a head clamping and recovery assembly on the correction seat, the tail clamping and recovery assembly utilizes a first rotary clamping shaft on the first clamping and recovery seat and a second rotary clamping shaft based on a swing arm. When the photoelectric sensor detects the tail of the old material roll, the swing drive cylinder drives the sliding rack to slide, thereby driving the swing drive gear and the swing arm to rotate, which in turn drives the second rotary clamping shaft to swing from the bottom to the front of the tail. This clamps the tail of the old material strip between the first and second rotary clamping shafts. Simultaneously, the material head clamping and recovery assembly uses a third and fourth rotary clamping shaft respectively installed on the second clamping and recovery seat. Several material head pressure plates are also installed on the second clamping and recovery seat, and quick-clamp assemblies are placed on these pressure plates. The head of the new material strip is manually passed between the third and fourth rotary clamping shafts, and the quick-clamp assemblies initially clamp and fix the head to the material head pressure plates. Then, a downward clamping cylinder drives the fourth rotary clamping shaft downwards, thus achieving the clamping and fixing of the material head. The welding assembly uses a first welding assembly located directly above the material tail clamping station on the correction seat, and a second welding assembly on the second clamping and recovery seat. The process involves a second pushing cylinder moving a second clamping and recovery seat and a second fusion assembly toward a first fusion assembly to align the material head and material position. Subsequently, the first fusion heating strip of the first fusion assembly and the second fusion heating strip of the second fusion assembly heat and fuse the material head and material position, automatically connecting the new material head to the old material tail without manual heating. After fusion, air is blown through the air hole to promote cooling and condensation. Then, the second pushing cylinder resets the second clamping and recovery seat, and simultaneously, the first pushing cylinder resets the first clamping and recovery seat, allowing the material belt to continue conveying. However, the connection strength between the remaining material head and tail and the material belt is significantly reduced after fusion.This process allows the residual material head and tail, held in place by the head and tail clamping and recovery components, to be pulled away from the weld joint as the conveyor belt moves along. Finally, the first and second rotary clamping shafts open, allowing the residual material tail to fall into the recovery trough. The third rotary clamping shaft then separates from the second, and the residual material head is manually collected. This significantly reduces the workload for operators and improves material handling efficiency. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: refer to Figures 1 to 10 An automatic feeding device for a cutting machine includes a base 1 and a correction seat 2 that is movably connected to the base 1. The correction component is movably connected to the base 1 based on a correction electric cylinder to realize automatic correction of the material belt. Support seats 3 for supporting the rotation of the material belt shaft are symmetrically fixedly connected at both ends of the bottom of the correction seat 2 along the material belt conveying direction. Automatic feeding component 4 for realizing automatic feeding of the material belt shaft and driving the material belt shaft to rotate to realize material release is fixedly connected to the correction seat 2. Material tail clamping and recycling component 5 for positioning and fixing the tail of the old material belt and realizing material tail recycling and material head clamping and recycling component 6 for positioning and fixing the head of the new material belt and realizing material head recycling are also fixedly provided on the correction seat 2. Fusion component 7 for docking the head of the new material belt with the tail of the old material belt and heating and fusing them is also provided on the correction seat 2.

[0021] refer to Figures 2 to 6 Specifically, the automatic feeding assembly 4 includes a lifting and feeding assembly 41, which is fixedly connected to the correction seat 2, for lifting the material belt shaft to the support seat 3, and a transfer assembly 42 for transferring the material belt shaft from the preparation station to the feeding station. The preparation station is located at the head of the support seat 3 away from the laying assembly, and the feeding station is located in the middle of the support seat 3. The correction seat 2 is fixedly connected to the feeding station with a feeding drive assembly 43 that drives the material belt shaft to rotate to realize feeding. The support seat 3 is inclined downward along the material belt conveying direction. The correction seat 2 is provided with a buffer platform 44 for buffering the air shaft 8 at one end of the support seat 3 away from the preparation station. When the material roll at the feeding station is fed out, the air shaft 8 automatically rolls into the buffer platform 44 due to gravity to realize automatic feeding.

[0022] refer to Figures 2 to 6Specifically, the lifting and feeding assembly 41 includes lifting blocks 412 that are symmetrically slidably connected to both ends of the correction seat 2 along the vertical direction based on the vertical slide rail 411. A lifting cylinder 413 is fixedly connected to the correction seat 2 along the vertical direction to drive the lifting blocks 412 to lift. A protruding blocking block 414 is fixedly connected to the end of the lifting blocks 412 away from the support seat 3 to prevent the material roll from falling. The two ends of the air shaft 8 are supported on the lifting blocks 412. The material roll is fixed on the air shaft 8. The material roll and the air shaft 8 are combined to form a material belt shaft. The lifting blocks 412 and the material belt shaft are lifted up by the lifting cylinder 413 to be lifted onto the support seat 3. By using the lifting and feeding assembly 41, the traditional method of manually lifting the air shaft 8 carrying the material roll to the preparation position is avoided. The material roll can be loaded simply by manually rolling the air shaft 8 onto the lifting blocks 412 of the lifting and feeding assembly 41, which greatly reduces the labor intensity. The transfer assembly 42 includes a horizontal transfer seat 422 symmetrically slidably connected to both ends of the support base 3 based on a first horizontal slide rail 421, and a lifting cylinder 423 fixedly connected to the horizontal transfer seat 422 in the vertical direction.

The two drive pulleys 425 are connected by a concentrically arranged synchronous connecting shaft 427. The synchronous drive motor 428, which drives the synchronous connecting shaft 427 to rotate, is fixedly connected to the correction seat 2. The synchronous drive motor 428 is based on belt drive to drive the synchronous connecting shaft 427 to rotate. When the material belt shaft rises to the preparation position, the synchronous drive motor 428 drives the synchronous connecting shaft 427 to rotate, thereby driving the drive pulley 425 to rotate. The drive pulley 425 drives the driven pulley 426 to rotate, thereby driving the conveyor belt to realize the conveying. Then, the horizontal transfer seat 422 is driven to slide along the first horizontal slide rail 421 to the preparation position. The lifting cylinder 423 drives the U-shaped positioning block 424 to rise, thereby lifting the material belt shaft. Subsequently, the horizontal transfer seat 422 drives the material belt shaft to move to the loading position to realize the automatic loading of the material roll.The feeding drive assembly 43 includes a pressing cylinder 431 fixedly connected vertically to the correction seat 2, and a U-shaped pressing clamp fixedly connected to the telescopic end of the pressing cylinder 431 for positioning the end of the pressing air shaft 8. A first drive gear 433 is fixedly connected coaxially to the end of the air shaft 8. A second drive gear 434, which meshes with the first drive gear 433, is rotatably connected to the correction seat 2. A feeding drive motor 435, which drives the second drive gear 434 to rotate, is fixedly connected to the correction seat 2. By positioning the pressing cylinder 431 and pressing down the U-shaped pressing clamp, the end of the air shaft 8 is positioned between the support seat 3 and the U-shaped pressing clamp. Subsequently, the feeding drive motor 435 drives the second drive gear 434 to rotate, which in turn drives the first drive gear 433 and the material belt shaft to rotate, thereby achieving automatic feeding. In this embodiment, the feeding drive motor 435 is a servo motor.

[0023] refer to Figure 7 Specifically, the material tail clamping and recycling assembly 5 includes a first clamping and recycling seat 52 slidably connected to the correction seat 2 along the horizontal direction based on the second horizontal slide rail 51, and a first pushing cylinder 53 fixedly connected to the correction seat 2 along the horizontal direction for pushing the first clamping and recycling seat 52 to the material tail clamping station.

A recycling trough 514 for collecting the tail of the old material strip is fixedly connected directly below the initial position of the first clamping and recycling seat 52. The tail clamping position is located at the first fusion assembly 7. Directly below position 1, the first clamping and recycling seat 52 is moved from the initial position to the material tail clamping position by the first pushing cylinder 53. When the photoelectric sensor 513 senses the material tail of the old material roll, the swing driving cylinder 512 drives the sliding rack 511 to slide, thereby driving the swing driving gear 510 and the swing arm 55 to rotate, thereby driving the second rotating clamping shaft 56 to swing and rotate from the bottom to the front of the material tail, thereby clamping the material tail of the old material strip between the first rotating clamping shaft 54 ​​and the second rotating clamping shaft 56.

[0024] refer to Figure 4 and Figure 8 Specifically, the material head clamping and recycling assembly 6 includes a second clamping and recycling seat 62 that is slidably connected to the correction seat 2 along the horizontal direction based on a third horizontal slide rail 61, and a second pushing cylinder 63 that is fixedly connected to the correction seat 2 along the horizontal direction for driving the second clamping and recycling seat 62 to slide. A third rotating clamping shaft 64 that abuts against the lower surface of the new material head is rotatably connected to the second clamping and recycling seat 62 along the horizontal direction. A fourth rotating clamping shaft 66 that abuts against the upper surface of the new material head is also slidably connected to the second clamping and recycling seat 62 along the vertical direction based on a pressing clamping cylinder 65. A plurality of material head pressure plates 67 are uniformly fixedly connected to the second clamping and recycling seat 62 along the horizontal direction. A quick-clamp assembly 68 is fixedly connected to the material head pressure plate 67 for initially clamping and fixing the head of the new material strip onto the material head pressure plate 67. The material head clamping and recycling assembly 6 is provided with a third rotary clamping shaft 64 and a fourth rotary clamping shaft 66 respectively on the second clamping and recycling seat 62. At the same time, several material head pressure plates 67 are provided on the second clamping and recycling seat 62 and quick-clamp assemblies 68 are provided on the material head pressure plates 67. The head of the new material strip is manually passed between the third rotary clamping shaft 64 and the fourth rotary clamping shaft 66, and the quick-clamp assembly 68 initially clamps and fixes the head onto the material head pressure plate 67. Then, the downward clamping cylinder 65 drives the fourth rotary clamping shaft 66 to press down, thereby achieving the clamping and fixing of the head.

[0025] refer to Figures 9 to 10Specifically, the fusion assembly 7 includes a first fusion assembly 71 fixedly connected to the correction seat 2 located directly above the material tail clamping station, used to abut against the inner surface of the old material strip tail, and a second fusion assembly 72 fixedly connected to the second clamping and recycling seat 62, used to abut against the outer surface of the new material strip head. The first fusion assembly 71 includes a fusion fixing seat 711 fixedly connected to the correction seat 2 along the horizontal direction and a first fusion heating strip 712 fixedly connected to the fusion fixing seat 711 along the horizontal direction. The second fusion assembly 72 includes a second fusion heating strip 73 fixedly connected to the second clamping and recycling seat 62 along the horizontal direction. Air blowing pipes 74 are fixedly connected to the bottom of the first fusion heating strip 712 and the second fusion heating strip 73 respectively at the bottom of the fusion fixing seat 711 and the second clamping and recycling seat 62. Several air blowing holes 75 are evenly opened along the horizontal direction on the air blowing pipes 74 for blowing air outward to promote the cooling and condensation of the fusion part. The fusion assembly 7 is constructed by placing a first fusion assembly 71 directly above the material tail clamping station on the correction seat 2 and a second fusion assembly 72 on the second clamping and recovery seat 62. A second push cylinder 63 drives the second clamping and recovery seat 62 and the second fusion assembly 72 toward the first fusion assembly 71, thereby achieving the bonding and docking of the material head and material position. Subsequently, the first fusion heating strip 712 of the first fusion assembly 71 and the second fusion heating strip 73 of the second fusion assembly 72 heat and fuse the material head and material position, automatically connecting the head of the new material strip to the tail of the old material strip without manual heating and docking. After fusion, the air blowing hole 75 blows air onto the fusion area to promote cooling and condensation. Then, the second push cylinder 63 drives the second clamping and recovery seat 62 to reset, while the first push cylinder 53 drives the first clamping and recovery seat 52 to reset, and the material strip continues to be conveyed. Due to the high connection strength between the residual material head and tail and the material strip after fusion, the fusion process is successful. The material head and tail, which are held together by the head clamping and recovery assembly 6 and the tail clamping and recovery assembly 5, are pulled away from the weld joint as the conveyor belt is transported. Finally, the first rotary clamping shaft 54 ​​and the second rotary clamping shaft 56 open, and the residual tail falls into the recovery tank 514. The third rotary clamping shaft 64 separates from the second rotary clamping shaft 56, and the residual head is manually recovered. A useful [material / equipment] is also fixedly connected to the weld fixing seat 711 and the second clamping and recovery seat 62. The material pushing assembly 76 pushes the material strip outward so that the material strip after receiving the material is separated from the first fusion heating strip 712 and the second fusion heating strip 73. The material pushing assembly 76 includes a material pushing cylinder 761 fixedly arranged in the horizontal direction and a material pushing plate 762 fixedly connected to the sliding end of the material pushing cylinder 761 in the horizontal direction. The material pushing cylinder 761 drives the material pushing plate 762 to extend and abut against the material strip, thereby causing the fused material strip to separate from the first fusion heating strip 712 and the second fusion heating strip 73.

[0026] Example 2: An automatic material receiving method for a cutting machine, employing an automatic material receiving device for a cutting machine as shown in Example 1, includes: Step 1: Push the new material roll to the preparation station. The automatic material feeding component 4 automatically conveys the new material roll to the feeding station and automatically unloads the old material roll. Step 2: Pull out the head of the new material strip and pull it to the head clamping and recycling component 6 to achieve initial fixation of the head of the new material strip; Step 3: The tail of the old material strip is clamped and fixed by the tail clamping recycling component 5. The fusion component 7 connects the head of the new material strip with the tail of the old material strip and heats and fuses them together, thereby automatically connecting the head of the new material strip to the tail of the old material strip. Step 4: The head clamping and recycling assembly 6 and the tail clamping and recycling assembly 5 separate from the fusion joint of the conveyor belt. The residual head and tail of the material, which are held clamped by the head clamping and recycling assembly 6 and the tail clamping and recycling assembly 5, are pulled away from the fusion joint as the conveyor belt is conveyed.
