Description

Technical Field

[0001] This specification relates to the technical field of photovoltaic modules, and in particular to an EVA cutting and laying device. Background Art

[0002] An EVA cutting and laying machine is used to cut and lay EVA (ethylene-vinyl acetate copolymer) material. EVA material is widely used in footwear, packaging, sports equipment, and other fields, and is highly sought after for its excellent cushioning properties and plasticity. When used to encapsulate photovoltaic modules, the EVA cutting and laying machine can precisely cut the EVA film and lay it on the glass substrate, ensuring an even, bubble-free encapsulation layer, which directly affects the module's weather resistance and power generation efficiency.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] See also Figures 1 to 14 The embodiment of the present application provides an EVA cutting and laying device, comprising a fixed base 1 , an adjustable frame 2 , a deviation correction motor 3 , a feeding mechanism 4 and a pulling and laying mechanism 5 .

[0028] Among them, such as Figure 1 and Figure 14 As shown, the fixed base 1 is provided with a plurality of slide rails 11 extending along a first direction X. Two rows of slide rails 11 are spaced apart in the first direction X, and each row of slide rails 11 contains a plurality of slide rails 11 spaced apart in the second direction Y. The first direction X, the second direction Y and the vertical direction Z are perpendicular to each other, and the first direction X and the second direction Y are two directions perpendicular to each other in the horizontal plane. The adjustable frame 2 is slidably connected to the slide rails 11, for example, the adjustable frame 2 can be connected to the slide rails 11 via a slider. The correction motor 3 is connected to the adjustable frame 2 for driving the adjustable frame 2 to move in the first direction X.

[0029] like Figure 1 As shown, the feeding mechanism 4 includes a coil conveying component 41, a hot melt conveying component 42 and a cutting hot melt component 43 which are arranged in sequence.

[0030] like Figure 2 As shown, the web conveyor assembly 41 includes a first conveyor track 411 and a pusher 412. The first conveyor track 411 extends along the second direction Y and is fixedly connected to the adjustable frame 2, thereby being movable with the adjustable frame 2. The first conveyor track 411 is provided with an initial position 4111 and an end position 4112 at both ends. The pusher 412 is slidably connected to the first conveyor track 411 and moves between the initial position 4111 and the end position 4112.

[0031] The hot melt conveying assembly 42 is located downstream of the coil conveying assembly 41. The "downstream" in this embodiment is related to the process, rather than indicating the up and down direction. Figure 4 As shown, the hot melt conveyor assembly 42 includes a second conveyor track 421, a fixed plate 422, and a first pressure plate 423. The second conveyor track 421 extends along the second direction Y and is fixedly connected to the fixed base 1. The fixed plate 422 is slidably mounted on the second conveyor track 421 at both ends in the first direction X. The first pressure plate 423 is movably mounted above the fixed plate 422. When the distance between the first pressure plate 423 and the fixed plate 422 is zero, it is used to clamp the EVA film on the standby roll.

[0032] The cutting hot melt assembly 43 is located downstream of the hot melt delivery assembly 42. Figure 5 As shown, the cutting hot melt assembly 43 includes a fixed seat 431, a second pressure plate 432, a cutter 433, and a heating wire 434. The fixed seat 431 is fixedly connected to the fixed base 1. The second pressure plate 432 is movably arranged above the upper surface of the fixed seat 431. When the distance between the second pressure plate 432 and the upper surface of the fixed seat 431 is zero, it is used to clamp the EVA film of the working material roll (the working material roll is the material roll currently in use, which is distinguished from the spare material roll). The heating wire 434 is fixedly arranged on the fixed seat 431, and the heating wire 434 and the fixed plate 422 are arranged to face each other. The cutter 433 is located below the heating wire 434.

[0033] like Figure 10 As shown, the material pulling and laying mechanism 5 is fixedly mounted on the fixed base 1. The material pulling and laying mechanism 5 is located downstream of the loading mechanism 4 and is used to pull the EVA film from the material roll and lay it on the photovoltaic module. The material pulling and laying mechanism 5 is arranged on one side of the loading mechanism 4 in the second direction Y.

[0034] The EVA cutting and laying device provided in this embodiment is provided with a fixed base 1, an adjustable frame 2, a correction motor 3, a feeding mechanism 4 and a pulling and laying mechanism 5. The feeding mechanism 4 includes a coil conveying component 41, a hot melt conveying component 42 and a cutting hot melt component 43. When the current used material roll is about to be used up, the spare material roll can be conveyed to the position (i.e., conveyed to the end position 4112) by the coil conveying component 41, and the EVA film at the beginning of the spare material roll can be conveyed to the cutting hot melt component 43 by the hot melt conveying component 42, so that the EVA film of the spare material roll and the EVA film of the used material roll are attached to each other, and the remaining part of the used material roll is bonded to the spare material roll by the heating wire 434 of the cutting hot melt component 43, so that the spare material roll can be used directly later, which can save manual threading time and realize automatic loading.

[0035] For the cutting hot melt component 43, when the material roll is about to be used up, the EVA film of the remaining part of the material roll is pressed by the fixing seat 431 and the second pressing plate 432, and the excess EVA film is cut and removed by the cutter 433, which can effectively prevent excessive excess film from hindering the transportation process after the hot melt is completed. At the same time, the cut EVA film can be recycled for use in other processes, saving materials.

[0036] In addition, the first conveying track 411 is fixedly connected to the adjustable frame 2. When the material roll is offset, the correction motor 3 only needs to drive the adjustable frame 2 to drive the first conveying track 411 to move in the first direction X, so as to realize the correction of the position of the material roll. There is no need to stop the machine for correction operation, thereby improving work efficiency.

[0037] In this embodiment, the coil conveyor assembly 41 further includes a synchronous belt 413, to which a pusher 412 is fixedly connected. The synchronous belt 413 drives the pusher 412 to move between an initial position 4111 and an end position 4112. The synchronous belt 413 is preferably driven by a servo motor. There are two first conveyor rails 411, two pushers 412, and two synchronous belts 413. Both first conveyor rails 411 extend in the second direction Y. The two first conveyor rails 411 are spaced apart in the first direction X. The two pushers 412 are disposed opposite each other in the first direction X.

[0038] like Figure 3 As shown, the pusher 412 includes a base portion 4121 and a pusher portion 4122 for contacting the spare material roll, and can push the spare material roll from the initial position 4111 to the final position 4112. The bottom of the base portion 4121 is fixedly connected to the synchronous belt 413, so that the synchronous belt 413 can drive the base portion 4121 to move in the second direction Y. The middle portion of the base portion 4121 is slidably connected to the first conveyor track 411, and the first conveyor track 411 can define the movement trajectory of the pusher 412. Specifically, the base portion 4121 can be slidably connected to the first conveyor track 411 via a slider.

[0039] The bottom of the pusher portion 4122 is connected to the base portion 4121 via a spring 4123. A limiting post 4124 is provided at the top of the pusher portion 4122 for contact with the base portion 4121. The base portion 4121 has a notch on one side near the end position 4112. This notch is connected to and lower than the top surface of the base portion 4121. The middle portion of the pusher portion 4122 is rotatably connected to the base portion 4121 via a rotating shaft 4125, allowing the pusher portion 4122 to rotate relative to the base portion 4121. When the pushing member 412 is driven by the synchronous belt 413 to move along the second direction Y from the initial position 4111 to the end position 4112, the limiting column 4124 is abutted against the top surface of the base 4121, and the pushing portion 4122 can act on the spare material roll to realize the movement of the spare material roll; when the pushing member 412 is driven by the synchronous belt 413 to move along the second direction Y from the end position 4112 to the initial position 4111, the pushing portion 4122 will rotate in the opposite direction when encountering an obstacle, so that the limiting column 4124 is abutted against the notch, so that the pushing portion 4122 is lower than the top surface of the base 4121, so that it can pass through the obstacle smoothly. After passing the obstacle, the pushing portion 4122 rotates back to its original position under the action of the spring 4123 (that is, the limiting column 4124 is abutted against the top surface of the base 4121), so that the automatic loading of the spare material roll can be realized.

[0040] In this embodiment, the hot melt conveying assembly 42 is located above the end position 4112. There are two second conveying rails 421, and both second conveying rails 421 extend along the second direction Y. The two second conveying rails 421 are spaced apart in the first direction X. The fixing plate 422 and the first pressing plate 423 extend along the first direction X.

[0041] Specifically, such as Figure 4 As shown, the hot melt delivery assembly 42 also includes two first cylinders 424 respectively connected to the two ends of the first pressing plate 423, for driving the first pressing plate 423 to move along the vertical direction Z to approach or move away from the fixed plate 422.

[0042] In this embodiment, the cutting hot melt assembly 43 is further provided with an air blowing pipe 435, which is fixedly disposed on the fixing base 431 and located above the heating wire 434. The air blowing pipe 435 is provided with a plurality of air blowing holes 4351, which are evenly spaced in the first direction X.

[0043] Specifically, the upper surface of the fixed plate 422 is higher than the position of the heating wire 434 in the vertical direction Z, thereby ensuring that when the fixed plate 422 moves on the second conveying track 421 to close to the fixed seat 431, the EVA film of the spare material roll clamped by the fixed plate 422 and the first pressing plate 423 can be close to the heating wire 434.

[0044] In this embodiment, the fixed seat 431 and the fixed plate 422 are arranged facing each other in the second direction Y. When the fixed plate 422 moves close to the fixed seat 431, the EVA film of the spare material roll clamped by the first pressing plate 423 and the fixed plate 422 and the EVA film of the used material roll clamped by the second pressing plate 432 and the fixed seat 431 are both close to the heating wire 434, so that the heating wire 434 can heat and bond the two EVA films.

[0045] like Figure 5 As shown, in the first direction X, the length of the heating wire 434 is greater than the length of the blowing tube 435. The cutter 433 is connected to a second cylinder for driving the cutter 433 to move in the first direction X, so that the cutter 433 can cut the excess EVA film of the remaining part of the used material roll.

[0046] Specifically, the cutting and hot-melt assembly 43 further includes two third cylinders 436 connected to the two ends of the second pressing plate 432, respectively, for driving the second pressing plate 432 to move along the vertical direction Z to move closer to or away from the fixing base 431. The third cylinders 436 and the second pressing plate 432 are connected by a connecting rod unit 437 to rationally utilize space.

[0047] like Figure 1As shown, a roll reversing assembly 47 is also provided downstream of the cutting hot melt assembly 43. When the used roll is about to be used up, the remaining portion of the used roll is first reversed to the photoelectric sensing position. The third cylinder 436 controls the second pressure plate 432 to press down, compacting the remaining portion of the EVA film. The second cylinder drives the cutter 433 to move in the first direction X to cut the excess EVA film. This effectively ensures that there is no excess film that would interfere with the conveying process after the hot melt is completed. After the hot melt conveying assembly 42 conveys the EVA film at the beginning of the spare roll to a position close to the heating wire 434, the heating wire 434 heats it, and the air blower 435 blows air simultaneously, bonding the EVA film of the spare roll to the EVA film of the used roll, allowing the spare roll to be used directly later, saving the time of manual threading.

[0048] In this embodiment, the feeding mechanism 4 further includes a punching assembly 44 located downstream of the cutting and hot-melting mechanism, and the punching assembly 44 is located downstream of the roll reversing assembly 47. Figure 6 As shown, the punching assembly 44 includes a plurality of punches 441 spaced apart in a first direction X, and a collecting portion 442 located below the punches 441 . The punches 441 can punch the EVA film, and the small holes punched out of the EVA film can be collected by the collecting portion 442 .

[0049] Specifically, the collecting portion 442 is fixedly connected to the fixed base 1. The punching assembly 44 also includes a mounting base 443 for mounting the punch 441, and a positioning knob 444 connected to the mounting base 443. The mounting base 443 is slidably mounted on the fixed base 1, and the positioning knob 444 is used to drive the mounting base 443 to move along the first direction X, so that the punching position can be adjusted as a whole. The mounting base 443 is provided with a plurality of mounting holes 4431 in the first direction X, and the punch 441 is detachably mounted in the mounting hole 4431 by fasteners, so that the plurality of punches 441 can be respectively mounted in different mounting holes 4431 as needed, so that the punching position can be adjusted individually to meet the requirements of different punching positions.

[0050] In this embodiment, the feeding mechanism 4 further includes a guillotine cutting assembly 45 located downstream of the punching assembly 44. Figure 7 As shown, the guillotine cutting assembly 45 includes an upper blade 451, a lower blade 452, and a connecting rod 453. The lower blade 452 is fixedly connected to the fixed base 1, and the upper blade 451 is connected to the connecting rod 453. The connecting rod 453 drives the upper blade 451 toward or away from the lower blade 452. The upper blade 451 is driven by the connecting rod 453, and the upper blade 451 and the lower blade 452 neatly cut the EVA film. Specifically, the upper blade 451 and the lower blade 452 are respectively mounted on the blade holder. The positions of the upper blade 451 and the lower blade 452 are fine-tuned using the top screw and the tightening screw on the blade holder to effectively cut the EVA film.

[0051] In this embodiment, the feeding mechanism 4 further includes an unwinding tensioning assembly 46 located downstream of the cutting and hot-melting mechanism. The unwinding tensioning assembly 46 is located upstream of the gate cutting assembly 45 and downstream of the roll reversing assembly 47. Figure 8 As shown, the unwinding and tensioning assembly 46 includes a displacement sensor 461 and a floating roller 462. Displacement sensor 461 is fixedly connected to the fixed base 1 and is used to calculate the distance the EVA film has traveled. The floating roller 462 is slidably connected to the fixed base 1 in the vertical direction Z and is used to store the film. During the EVA film roll process, the displacement sensor 461 measures the distance, and the change in the length of the displacement sensor 461 reflects the material usage of the roll.

[0052] like Figure 1 and Figure 9 As shown, the feeding mechanism 4 also includes a pressure roller feeding assembly 48. The pressure roller feeding assembly 48 can feed the EVA film to the material receiving position, which is convenient for the material pulling clamp 511 to be clamped below. The pressure roller feeding assembly 48 is located between the punching assembly 44 and the guillotine cutting assembly 45.

[0053] In this embodiment, the pulling material laying mechanism 5 includes a pulling material assembly 51. Figure 11 As shown, the material pulling assembly 51 includes a plurality of material pulling jaws 511 spaced apart along a first direction X, which are used to clamp the EVA film output by the loading mechanism 4. The material pulling assembly 51 also includes a material pulling motor 512 connected to the material pulling jaws 511, which is used to drive the material pulling jaws 511 to move along a second direction Y to cover the photovoltaic module. The material pulling motor 512 is fixedly connected to the fixed base 1.

[0054] In this embodiment, the material laying mechanism 5 further includes a material pressing component 52. Figure 10 and Figure 12 As shown, the pressing assembly 52 and the pulling motor 512 are positioned relative to each other in the second direction Y, with the pressing assembly 52 positioned near the loading mechanism 4. After the pulling jaws 511 clamp the EVA film and convey it to the desired length, the pressing assembly 52 presses down, and the guillotine cutting assembly 45 cuts the film. The speed of the pulling assembly 51 and the pressing assembly 52 are kept consistent, aligning the EVA film and moving it horizontally to the center above the glass surface of the photovoltaic module.

[0055] In this embodiment, the material pulling and laying mechanism 5 further includes a lifting assembly 53, which is located below the material pulling assembly 51 and the material pressing assembly 52, and is used to drive the photovoltaic assembly to rise or fall along the vertical direction Z, thereby adjusting the distance between the photovoltaic assembly and the EVA film.

[0056] Specifically, the EVA film delivered by the pressure roller feeding assembly 48 is pulled out by the pulling assembly 51, and after being pulled to the required position, it is cut by the knife cutting assembly 45. The pressing mechanism presses the EVA film and moves the EVA film to the top of the photovoltaic module glass at a uniform speed. At the same time, the lifting mechanism lifts the glass, the pulling clamp 511 is released, and the corresponding cylinder extends to spread the EVA film flat on the glass.

[0057] In this embodiment, the pulling and laying mechanism 5 further includes a blocking and correcting component 54 for adjusting the position of the photovoltaic component. Figure 13 As shown, the blocking and correcting assembly 54 includes a first blocking portion 541, a second blocking portion 542, and a correcting portion 543. The first blocking portion 541 and the second blocking portion 542 are aligned and spaced apart in the second direction Y. The correcting portion 543 is located to one side of the first blocking portion 541 and the second blocking portion 542 in the first direction X, and is located between the first blocking portion 541 and the second blocking portion 542. This blocking and correcting assembly 54 uses three-point correction, and the blocking portion and the correcting portion 543 can be controlled independently. The position of the glass can be fine-tuned based on the position of the EVA film, achieving uniform positioning of the film and the glass.

[0058] like Figure 10 As shown, the conveyor line 55 extends along the first direction X and moves in the first direction X, and can convey the photovoltaic components to the material laying mechanism 5. After the EVA film is laid, the conveyor line 55 can move the photovoltaic components out.

[0059] It should be noted that, in the description of this specification, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be understood to indicate or imply relative importance. Furthermore, in the description of this specification, unless otherwise specified, "plurality" means two or more.

[0060] Any numerical value cited herein includes all values ​​of the lower and upper values ​​in increments of one unit from the lower value to the upper value, provided that there is at least a two-unit interval between any lower value and any higher value. For example, if the value of a component quantity or process variable (e.g., temperature, pressure, time, etc.) is stated to be from 1 to 90, preferably from 20 to 80, and more preferably from 30 to 70, it is intended to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32, etc. are also explicitly listed in this specification. For values ​​less than 1, one unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples intended to be clearly stated, and it is to be understood that all possible combinations of the values ​​listed between the minimum and maximum values ​​are explicitly stated in this specification in a similar manner.

[0061] Unless otherwise indicated, all ranges include the endpoints and all numbers between the endpoints. When used with a range, "about" or "approximately" applies to both endpoints of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30," including at least the specified endpoints.

The term "consisting essentially of..." when describing a combination should include the identified elements, ingredients, components, or steps and other elements, ingredients, components, or steps that do not materially affect the basic novel characteristics of the combination. The use of the terms "comprising" or "including" to describe a combination of elements, ingredients, components, or steps herein also contemplates embodiments consisting essentially of these elements, ingredients, components, or steps. By using the term "may," it is intended to indicate that any attribute described as "may" be optional.

[0063] Multiple elements, ingredients, parts or steps can be provided by a single integrated element, ingredient, part or step. Alternatively, a single integrated element, ingredient, part or step can be divided into separate multiple elements, ingredients, parts or steps. The disclosure of "a" or "an" to describe an element, ingredient, part or step is not intended to exclude other elements, ingredients, parts or steps.

[0064] It should be understood that the above description is for illustration and not for limitation. Many embodiments and many applications beyond the examples provided will be apparent to those skilled in the art upon reading the above description. Therefore, the scope of the present teachings should not be determined with reference to the above description, but rather with reference to the appended claims and the full scope of equivalents to which such claims are entitled. For the purpose of comprehensiveness, all articles and references, including disclosures of patent applications and publications, are incorporated herein by reference. The omission of any aspect of the subject matter disclosed herein from the foregoing claims is not intended to be a disclaimer of such subject matter, nor should it be assumed that the inventors did not consider such subject matter to be part of the disclosed inventive subject matter.
