[0029] In order to make the purpose, technical scheme and advantages of the present invention clearer, the following will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present invention, many technical details are provided in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed for protection in the claims of the present application can be implemented.

[0030] The first embodiment of the present invention relates to a rubber strip feeding device, such as Figure 1 , Figure 2 As shown, it includes an unwinding unit 1, a switching unit 2 and at least two transfer units. Among them, a number of material rolls for providing adhesive strips are placed on the unwinding unit 1, and the adhesive strips on each material roll pass through the corresponding transfer unit and wait for feeding, and the switching unit 2 drives one of the transfer units to start or stop providing adhesive strips.

[0031] It is not difficult to find from the above content that since the switching unit 2 drives one of the transmission units to start or stop providing the rubber strips, and there are at least two transmission units, when one of the transmission units is out of material, the switching unit can drive other transmission units to provide the rubber strips, thereby ensuring continuous loading of the rubber strips and thereby improving production efficiency.

[0032] In this embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, there are two unwinding units 1 and two transfer units, respectively, and the two transfer units are arranged in sequence from top to bottom in the vertical direction. Correspondingly, the two unwinding units 1 are arranged opposite to each other in the vertical direction. Each unwinding unit 1 can provide four rubber strips. The upper transfer unit transfers the rubber strip on the upper unwinding unit, and the lower transfer unit transfers the rubber strip on the lower unwinding unit. Specifically, the transfer unit includes a clamping structure 4 and a guide structure 3. The guide structure 3 has a transfer channel through which the rubber strip passes, and the width of the space through which the rubber strip is allowed to pass through the transfer channel is adjustable. The clamping structure 4 clamps the rubber strip. The transfer direction of the rubber strip is guided by the guide structure 3, and the rubber strip is clamped by the clamping structure 4, so that the rubber strip can be docked with the next workstation. In actual use, one transfer unit can correspond to one unwinding unit 1, or to multiple unwinding units 1; the unwinding unit 1 adopts a conventional coil rotating frame, and the material roll is sleeved on the rotating shaft to provide the rubber strip.

[0033] like Figure 2As shown, in this embodiment, the switching unit 2 includes a moving bracket 21 and a cylinder 22. Each transmission unit is arranged on the moving bracket 21, and the cylinder 22 is connected to the moving bracket 21, and drives the moving bracket 21 to move along a preset path, so that one of the transmission units moves to the working position and starts to provide the rubber strip, while the other transmission unit stops providing the rubber strip. Specifically, in this embodiment, the moving bracket 21 moves up and down in a direction perpendicular to the traction platform. In actual use, the process of the switching unit 2 driving the transmission unit to switch can be manually controlled by the staff, and can also be connected to a main control system such as a PLC for automatic control.

[0034] Further, such as Figure 4 , Figure 5 , Figure 6As shown, in this embodiment, the guide structure 3 includes a mounting assembly 31, a first guide assembly 32 and a second guide assembly 33. Specifically, the first guide assembly 32 includes five guide posts 321 and five adjustment nuts 322, and a first transfer area through the rubber strip is formed between two adjacent guide posts 321; the mounting assembly 31 includes: a fixing plate 311 with a U-shaped groove, a lower positioning plate 312 disposed in the U-shaped groove, and an upper positioning plate 313 disposed opposite to the lower positioning plate 312, and five groups of waist-shaped holes 314 are provided on the upper positioning plate 313 and the lower positioning plate 312. Among them, the upper positioning plate 313 has a groove on one side facing the lower positioning plate 312, and the groove of the upper positioning plate 313 and the lower positioning plate 312 enclose an area through the rubber strip. The waist-shaped hole of the lower positioning plate 312 is provided with a protrusion 315 on the side wall. The side of the protrusion 315 facing the upper positioning plate 313 abuts against the corresponding guide column 321, and the side of the protrusion 315 away from the upper positioning plate 313 forms a receiving groove for accommodating the adjusting nut 322. After the guide column 321 passes through the corresponding waist-shaped holes 314 on the upper positioning plate 313 and the lower positioning plate 312, the adjusting nut 322 is locked and fixed with the guide column 321 and enters the receiving groove of the lower positioning plate 312. When the width of the rubber strip to be transferred changes, the position of the guide column 321 in the waist-shaped hole 314 can be adjusted by loosening the adjusting nut 322. The guide column 321 can change the width of the first transfer area during the adjustment process. After the guide column 321 is adjusted to a suitable position, the guide column 321 is locked and fixed with the lower positioning plate 312 by the adjusting nut 322 to ensure that the width of the first transfer area is fixed, so that rubber strips of different widths can be transferred conveniently. In addition, in the present embodiment, two waist-shaped holes form a group. In actual use, the upper positioning plate 313 and the lower positioning plate 312 can also be composed of a whole plate body, and through holes for passing the rubber strips are opened at the corresponding positions. The number of waist-shaped holes 314, guide columns 321, and adjustment nuts 322 are adjusted according to the number of rubber strips required to be transferred. In addition, the adjustment method of the first guide component 32 and the installation component 31 can be adaptively adjusted according to actual conditions. For example, a slide rail is set on the installation component 31, and the first guide component 32 adopts a guide column that can slide along the slide rail. The spacing between two adjacent guide columns is adjusted by sliding, thereby facilitating the transfer of rubber strips of different widths. Of course, the first guide component 32 can also adopt other adjustable structures according to the usage.

[0035] Further, such as Figure 4As shown, in this embodiment, the second guide assembly 33 includes a rotating shaft 331 and a sleeve 332. The rotating shaft 331 is detachably arranged on the moving bracket 21. The sleeve 332 is sleeved on the rotating shaft 331 and can rotate around the rotating shaft 331. Five guide wheels 333 are arranged on the sleeve 332. A second transfer area through the rubber strip is formed between two adjacent guide wheels 333. The first transfer area and the second transfer area together constitute a transfer channel through the rubber strip. When the width of the rubber strip to be transferred changes, the spacing of the second transfer area can be changed by replacing the sleeve 332. In actual use, the second guide assembly 33 can also adopt other structures. For example, a plurality of rollers are sleeved on the rotating shaft 331. The space between two adjacent rollers is used to pass the rubber strip. When the width of the rubber strip changes, the spacing of the second transfer area can be adjusted by adjusting the position of the rollers.

[0036] In addition, in this embodiment, since each transfer unit is arranged vertically and the rubber strip is a flexible strip, the rubber strip is prone to drooping during the process in which the unwinding unit located above transfers the rubber strip to the second guide assembly 33. Figure 3 , Figure 4 As shown, a supporting plate 34 is also provided on the upper transfer unit, and the supporting plate 34 is located at the lower end of the second guide assembly 33. Specifically, the supporting plate 34 includes a vertical section 341 provided on the fixed plate 311, an inclined section 342 supporting the rubber strip, and a horizontal section 343 connecting the vertical section 341 and the inclined section 342; the horizontal section 343 is provided with five through holes equidistantly along its length direction, and each through hole is provided corresponding to the guide wheel 333 on the sleeve 332, and the width of the through hole is greater than the width of the guide wheel 333, so as to ensure that the supporting plate 34 does not need to be replaced when the sleeve is replaced due to the change in the width of the rubber strip. The inclined section 342 is inclined from the horizontal section 343 toward one side of the unwinding unit 1, and the rubber strip is supported by the inclined section 342 of the supporting plate 34, which can effectively prevent the rubber strip from drooping and ensure smooth transportation of the rubber strip. In actual use, a supporting plate 34 may also be provided on each transfer unit, and the number and arrangement of the supporting plates 34 may be adjusted according to actual conditions.

[0037] In addition, in this embodiment, if Figure 4As shown, the pressing structure 4 includes a pressing cylinder 41, a pressing plate 42, a pressing rod 43, a pressing block 44 and a spring 45. Specifically, the pressing cylinder 41 is arranged on the moving bracket 21, the pressing plate 42 is connected to the pressing cylinder 41, the spring 45 is sleeved on the pressing rod 43 and connects the pressing plate 42 and the pressing block 44, the pressing rod 43 is slidably arranged on the pressing plate 42, and the pressing block 44 is arranged on the side of the pressing rod 43 away from the pressing plate 42 and is used to press the rubber strip. When the rubber strip needs to be pressed, the pressing cylinder 41 drives the pressing plate 42 to descend, the pressing block 44 first contacts the rubber strip, and the pressing plate 42 continues to move downward along the pressing rod 43, the spring 45 is compressed, and at the same time, the rubber strip is pressed by the pressing block 44 on the fixed plate 311 of the mounting assembly 31. Moreover, in this embodiment, two clamping cylinders 41 are provided, and one clamping cylinder 41 corresponds to a pressure plate 42, two pressure rods 43, two springs 45 and two pressure blocks 44, so that when any clamping cylinder 41 is working, two rubber strips can be compressed at the same time.

[0038] Further, such as Figure 7 As shown, in this embodiment, the rubber strip feeding device also includes: a plurality of opposing photoelectric switches 5, which are respectively arranged on each unwinding unit 1. Specifically, opposing photoelectric switches 5 are respectively arranged on both sides of the unwinding unit 1, and the opposing photoelectric switches 5 on both sides emit and receive light to each other. When the two opposing photoelectric switches 5 cannot receive each other's light, it proves that there is still rubber strip on the roll, and when the two opposing photoelectric switches 5 contact each other's light, it proves that the roll is short of material and needs to be replaced. Therefore, by setting the opposing photoelectric switches 5, the shortage reminder can be realized at a low cost. In actual use, the position and number of the opposing photoelectric switches 5 can be determined according to the usage.

[0039] In addition, if Figure 1 , Figure 7 As shown, in this embodiment, the rubber strip feeding device also includes a hot melt machine 6. When the material roll is short of material, the rubber strip at the end of the previous material roll and the rubber strip at the head of the next material roll are placed at the hot melt machine 6. The hot melt machine 6 heats the two rubber strips and melts and solidifies them, so that the rubber strips are combined into one. Therefore, there is no need to manually pass the rubber strips to the pressing structure 4 again, so that the material rolls can be quickly replaced. The hot melt machine is an existing technology and can be directly purchased and used, and will not be described here.

[0040] The rubber strip feeding device provided in this embodiment first sets the material roll on the two unwinding units 1 respectively. After the rubber strip on the material roll passes through the corresponding second guide component 33 and the first guide component 32, it is compressed by the clamping structure 4 and waits for feeding. Then, the switching unit 2 first drives one of the transfer units to start providing the rubber strip, and the rubber strip is pulled to the traction platform under the clamping action of the transverse clamping unit; when the material roll is out of material, the switching unit 2 drives the current transfer unit to stop providing the rubber strip, and drives the next transfer unit to start providing the rubber strip at the same time, thereby realizing continuous feeding of the rubber strip; during the process of the next transfer unit providing the rubber strip, the material roll on the previous unwinding unit is quickly replaced by the hot melt machine 6.

[0041] A second embodiment of the present invention relates to a long rubber strip laying machine, such as Figure 8 As shown, it includes a traction platform 7 and a rubber strip feeding device as described in the first embodiment, a transverse clamping unit 8, a cutting unit 9 and a grabbing and placing unit 10. Among them, the traction platform 7 is arranged outside the rubber strip laying area, and the length direction of the traction platform 7 is the same as the length direction of the rubber strip laying area, and the rubber strip feeding device provides the rubber strip to the traction platform 7; the transverse clamping unit 8 has a clamping part for clamping the rubber strip, and the cutting unit 9 is arranged between the traction platform 7 and the rubber strip feeding device, and has a cutting part for cutting the rubber strip; the grabbing and placing unit 10 is slidably arranged above the traction platform 7. When the rubber strip feeding device provides the rubber strip, the clamping part clamps the rubber strip and moves along the length direction of the traction platform 7, and after moving to a preset position, the cutting part cuts the rubber strip, and then the grabbing and placing unit 10 grabs the rubber strip and takes it away from the traction platform 7, and places the rubber strip on the long side of the photovoltaic module.

[0042] Specifically, in this embodiment, if Figure 8 , Fig. 9 As shown, two transverse clamping units 8 are provided, and the two transverse clamping units are driven by independent power sources respectively. The rubber strip is pulled to the traction platform under the drive of the transverse clamping unit, and the rubber strip can be taken and prepared by two independently moving transverse clamping units. Since the rubber strip is a flexible strip, it cannot be pulled too quickly. Therefore, the design of taking and preparing one is convenient to ensure the working rhythm of laying the rubber strip and effectively ensure the working rhythm. At the same time, in this embodiment, the transverse clamping unit 8 includes a driving cylinder 81 and two clamping claws 82 connected to the driving cylinder 81. The two clamping claws 82 are the clamping parts of the transverse clamping unit. Therefore, when one transverse clamping unit 8 moves, it can clamp two rubber strips at the same time.

[0043] In this embodiment, if Fig.10As shown, the cutting part of the cutting unit 9 is a cutter. Specifically, the cutting unit 9 includes: a crossbeam 91 arranged on the frame, a cutting seat 92 slidably arranged on the crossbeam 91, a motor 93 arranged on the crossbeam 91, a cutting cylinder 94 and a connecting plate 95 arranged on the cutting seat 92, a mounting plate 96 arranged on the connecting plate 95, a cutter 97 arranged on the mounting plate 96, a cutter protection plate 98 slidably arranged on the connecting plate 95, and a spring 99 connecting the cutter protection plate 98 and the connecting plate 95; the motor 93 is used to drive the cutting seat 92 to move horizontally along the length direction of the crossbeam 91, and the cutting cylinder 94 is used to drive the cutter 97 to move up and down, and when the cutter 97 rises to the initial position, the distance from the cutter protection plate 98 to the traction platform 7 is smaller than the distance from the cutter 97 to the traction platform 7. The cutter protection plate 98 extends out of the blade position under the elastic action of the spring 99. When the cutting cylinder 94 drives the cutter 97 to move downward, the cutter protection plate 98 first contacts the rubber strip. At this time, the cutter protection plate 98 abuts against the traction platform 7 and no longer descends, playing the role of pressing the rubber strip. The cutter 97 continues to move downward, the spring 99 is compressed, and the cutter 97 moves to the traction platform 7 to cut the rubber strip. Then the cutting cylinder 94 drives the cutter 97 to rise upward. Under the action of the spring 99, the cutter protection plate 98 moves downward relative to the cutter 97, gradually covers the cutter 97, and finally leaves the traction platform 7 together with the cutter 97. In addition, in this embodiment, the cutter 97 adopts a pentagonal design, and the five sides are all blades. When the blade needs to be replaced, it is only necessary to remove the cutter and change the angle, without having to replace the cutter material again; at the same time, the cutter protection plate 98 can not only protect the cutter 97 from being broken by foreign objects, but also has holes to facilitate the equipment personnel to observe the state of the cutter 97 at any time. In actual use, the cutting unit can be set according to the related technology of laying the rubber strip in the prior art, as long as it can cut the rubber strip.

[0044] In addition, if Figure 8 As shown, the grabbing and placing unit 10 includes a plurality of suction cups 101, a vacuum generator connected to the suction cups 101, and a three-dimensional module 102 that drives each suction cup 101 to move. All suction cups 101 are connected to the vacuum generator through a pipeline, and the three-dimensional module 102 drives the suction cups 101 to move along a preset path. In actual use, the rubber strip can also be grabbed by clamping or other methods. The specific structure of the three-dimensional module 102 can be set according to the relevant technology of laying rubber strips in the prior art, as long as it can drive each suction cup to move along a preset direction.

[0045] As the quality requirements of photovoltaic modules increase, not only will short rubber strips be placed in the middle and at both ends of the short sides of the modules, but long rubber strips will also be added to the long sides of the photovoltaic modules to further ensure the position stability of the modules, so as to greatly reduce the displacement and bubbles during the lamination process. The long rubber strip laying machine provided in this embodiment can automatically lay rubber strips on the long sides of the photovoltaic modules, and use two independently moving transverse clamping units 8 to achieve one-to-one preparation of the rubber strips. Therefore, there are always cut long rubber strips on the traction platform, and the grabbing and placing unit 10 can continuously place the cut long rubber strips on the long sides of the photovoltaic modules, effectively improving production efficiency.

[0046] Those skilled in the art can understand that the above-mentioned embodiments are specific examples of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
