[0035] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in more different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0036] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] In the present utility model, unless otherwise clearly stipulated and limited, a first feature “below”, “below” and “under” a second feature includes the first feature being directly below and diagonally below the second feature, or simply means that the first feature is smaller in horizontal height than the second feature.

[0039] like Figure 1As shown, the insulating film strip 530 is arranged between the bus bar 540 and the electrode area, and the insulating film strip 530 is used to insulate the bus bar 540 from one of the first electrode area and the second electrode area. The bus bar 540 is electrically connected to the welding strip 520 connected to the fine grid corresponding to the through area 531 to prevent the battery cell from short-circuiting. This structure can effectively improve the current collection effect while hiding the bus bar 540 and ensure the beauty of the component. The photovoltaic component insulating film pasting equipment provided by the utility model is used to perform the film making and pasting process of the insulating film in the BC component processing process, complete the precise pasting of the insulating film strip 530, and improve the processing quality and processing efficiency of the BC component.

[0040] like Figure 2-Figure 4 As shown, the utility model provides a photovoltaic module insulating film pasting device, including a bracket 100, on which a conveying positioning mechanism 200, a film supply mechanism 300, and a film spreading mechanism 400 are installed. The conveying positioning mechanism 200 includes a conveying mechanism, a first positioning mechanism 210, and a second positioning mechanism 220. One of the first positioning mechanism 210 and the second positioning mechanism 220 is parallel to the conveying direction of the conveying mechanism, and the positioning directions of the first positioning mechanism 210 and the second positioning mechanism 220 are perpendicular to each other. The mechanism 200 moves the glass plate 550 with the battery string group 510 arranged thereon to the film pasting position through the conveying mechanism, and the first positioning mechanism 210 and the second positioning mechanism 220 perform a correction action on the glass plate 550 at the film pasting position to ensure that the glass plate 550 is at the preset film pasting position. The positioning mechanism only needs to be able to realize the correction function. The utility model does not specifically limit the structure of the first positioning mechanism 210 and the second positioning mechanism 220. After the film pasting action is completed, the glass plate 550 is moved out of the film pasting position and flows to the next process. Among them, the film supply mechanism 300 is arranged on both sides of the conveying direction of the conveying and positioning mechanism 200, and is used to prepare the insulating film strip 530 with the penetration area 531; the film spreading mechanism 400 is arranged above the conveying and positioning mechanism 200, and is used to move the insulating film strip 530 to the target position and paste the insulating film strip 530 at the preset position of the battery string group 510.

[0041] When the photovoltaic module insulating film pasting equipment is working, the glass plate 550 with the battery string group 510 is first transported to the film pasting position by the conveying mechanism, and the glass plate 550 is corrected by the first positioning mechanism 210 and the second positioning mechanism 220 to ensure that its position is at the preset film pasting position. At the same time, the film supply mechanism 300 located on both sides of the conveying direction of the conveying positioning mechanism 200 prepares the insulating film strip 530 with the through area 531. After that, the insulating film strip 530 prepared by the film supply mechanism 300 is transported to the target position by the film laying mechanism 400, and the insulating film strip 530 is pasted on the preset position of the battery string group 510. Finally, the glass plate 550 is moved to the next process by the conveying mechanism. Through the cooperation of the conveying and positioning mechanism 200, the film supply mechanism 300, and the film laying mechanism 400, an insulating film strip 530 with a penetration area 531 matching the welding strip on the battery string group is prepared, and the above-mentioned insulating film strip 530 is accurately attached to the battery string group 510, and the film making and film attaching process of the insulating film in the BC component processing process is performed to complete the accurate film attaching of the insulating film strip 530, thereby improving the processing quality and processing efficiency of the BC component.

[0042] It should be noted that there are three target positions mentioned above, namely the two ends and three groups of positions in the middle of the battery string group 510. When the film supply mechanisms 300 on both sides of the conveying and positioning mechanism 200 are making films, at least one side of the film supply mechanism 300 simultaneously prepares two parallel groups of insulating film strips 530. The film laying mechanism 400 is arranged correspondingly based on the film supply mechanism 300, and two groups of film taking assemblies 410 are arranged on the side where the two groups of insulating film strips 530 are arranged.

[0043] In the embodiment of the present utility model, Figure 5 As shown, the film supply mechanism 300 includes a punching mechanism 330, a cutting mechanism 340, a film pulling mechanism 350, and a film placing platform 360. The punching mechanism 330, the cutting mechanism 340, and the film placing platform 360 are sequentially arranged along the supply direction of the insulating film strip 530. The punching mechanism 330 is used to prepare a through area 531 on the insulating film strip 530. The film pulling mechanism 350 is arranged above the film placing platform 360 and is used to pull the insulating film strip 530 on the punching mechanism 330 and cut it into insulating film strips 530 through the cutting mechanism 340. The film placing platform 360 is used to receive the insulating film strip 530. Through the cooperation of the punching mechanism 330, the cutting mechanism 340, the film pulling mechanism 350, and the film placing platform 360, the insulating film strip 530 is prepared into an insulating film strip 530. Of course, the film supply mechanism 300 here also includes a film rolling mechanism and a weight mechanism 320. The insulating film strip 530 is released by the film rolling mechanism, and the released insulating film strip 530 is kept in a tensioned state under the action of the weight mechanism 320. This can avoid the insulating film strip 530 from being loosely wound and affecting the subsequent processing size of the insulating film strip 530.

[0044] Before film making, the insulating film strip 530 provided by the film rolling mechanism is manually wound through the weight mechanism 320 to the punching mechanism 330. When the film supply mechanism 300 is working, the punching mechanism 330 processes a through area 531 on the insulating film strip 530. Here, the shape of the through area 531 is preferably a long hole. The specific size and the spacing of the through area 531 are jointly determined by the width of the bus bar 540 and the spacing of the welding strip 520; then, the film pulling mechanism 350 pulls the insulating film strip 530 toward the film placing platform 360. When the insulating film strip 530 is pulled out to a specified length, the cutting mechanism 340 is started to cut the insulating film strip 530, so as to obtain the insulating film strip 530 with the preset size requirement; finally, the film pulling mechanism 350 lays the insulating film strip 530 on the film placing platform 360 and waits for transportation.

[0045] Furthermore, Figure 7-Figure 8 As shown, the punching mechanism 330 includes a template 331, a pressing plate 333, and a floating plate 334. The floating plate 334 is arranged between the template 331 and the pressing plate 333. A plurality of punches 332 are fixed on the pressing plate 333. The template 331 and the floating plate 334 are provided with die holes 337 matching the punches 332. Through the cooperation of the template 331, the pressing plate 333, the floating plate 334, and the punches 332, a through-area 531 with a stable shape can be punched out on the insulating film strip 530. In specific implementation, the template 331 is mounted and fixed on the support frame, and the pressing plate 333 and the floating plate 334 are arranged above the template 331. The floating plate 334 and the pressing plate 333 are abutted by a spring to ensure that the floating plate 334 can float relative to the pressing plate 333. In addition, when the punch 332 is installed, the punch 332 is fixed on the pressing plate 333 and inserted into the die hole 337 of the floating plate 334 without exceeding the lower end surface of the floating plate 334. When the punching mechanism 330 is working, the pressing plate 333 drives the floating plate 334 and the punch 332 to move toward the direction of the template 331. When the floating plate 334 abuts against the template 331, the insulating film strip 530 is fixed between the two. The floating plate 334 is forced to retract. During the retraction process, the pressure on the insulating film strip 530 is increased in the reverse direction, thereby improving the fixing effect of the insulating film strip 530, ensuring that the insulating film strip 530 will not be loose when the through-area 531 is punched, and ensuring the processing size of the insulating film strip 530; and during the retraction process, the punch 332 extends out of the floating plate 334 and is inserted into the die hole 337 of the template 331. The punch 332 cuts the corresponding part of the insulating film strip 530, thus completing the preparation of the through-area 531.

[0046] In addition, it should be noted that the die holes 337 on the template 331 and the floating plate 334 match the punches 332. The matching here includes at least two aspects. One is the matching of shape and size, that is, the punch 332 can just pass through the die hole 337, so that a through-area 531 with stable shape can be punched out; the second is the matching of quantity, that is, the number of punches 332 is consistent with the number of die holes 337.

[0047] In the embodiment of the utility model, the punching mechanism 330 includes a guide member 335 installed on the template 331, and the guide member 335 passes through the pressure plate 333 and the floating plate 334. The guiding direction of the guide member 335 is consistent with the matching direction of the punch 332 and the die hole 337. The pressure plate 333 and the floating plate 334 constrain movement in the guiding direction. Through the guiding effect of the guide member 335, the stability of the punching mechanism 330 during operation can be further improved, ensuring that a stable-shaped penetration area 531 is punched out on the insulating film strip 530.

[0048] The guide member 335 here can be a single guide post. When a single guide post is used, the guide holes on the pressing plate 333 and the floating plate 334 cooperate with the guide post; the guide member 335 here can also be a combination of a guide post and a guide sleeve. The guide sleeve is fixed on the pressing plate 333 and / or the floating plate 334, which can effectively reduce wear and extend the service life of the blanking mechanism 330. The above guide post or the combination of a guide post and a guide sleeve is an exemplary description of the guide member 335 and should not be understood as a specific limitation of the present invention. The function of the guide member 335 is to constrain the moving direction of the pressing plate 333 and the floating plate 334, so that the punch 332 can be accurately inserted into the die hole 337, and then cut out a through area 531 with a stable shape and no burrs.

[0049] like Figure 7 As shown, the punching mechanism 330 also includes a collecting box 336, which is located below the template 331. The collecting box 336 can be directly installed on the template 331 or on a support frame of the punching mechanism 330. The waste generated during the punching process can fall into the collecting box 336. In this way, the waste generated during the punching process is collected by the collecting box 336, which can not only keep the processing environment clean, but also facilitate the centralized treatment of the waste.

[0050] At the same time, if Fig. 9 As shown, the punch 332 is provided with an exhaust channel 3321 that penetrates therethrough, and the pressing plate 333 is provided with an air supply channel 3331 that is connected to the exhaust channel 3321. The air outlet of the exhaust channel 3321 is provided on the end surface of the punch 332 facing the insulating film strip 530. By providing the exhaust channel 3321, when the punch 332 completes the blanking action, air is inflated into the exhaust channel 3321, so that the waste material stuck to the bottom of the punch 332 is separated, ensuring that the punch 332 can work effectively and continuously.

[0051] And, if Figure 1 As shown, the distance between adjacent punches 332 is consistent with the distance between two solder strips 520 arranged at intervals on the battery string 510. When two adjacent penetration areas 531 on the insulating film strip 530 prepared in this way are aligned with the two solder strips 520, there is exactly one solder strip 520 hidden under the insulating area between the two adjacent penetration areas 531.

[0052] like Figure 8 As shown, in the embodiment of the utility model, the film supply mechanism 300 includes a fixing component 338, and the fixing component 338 is arranged at the feeding end of the punching mechanism 330. The function of the fixing component 338 is to fix the position of the insulating film strip 530 to prevent the insulating film strip 530 from retracting. Specifically, after the film pulling mechanism 350 clamps the insulating film strip 530, the punch 332 is lifted, and the film pulling mechanism 350 clamps the insulating film strip 530 and moves toward the film placing platform 360. When the preset length is reached, the fixing component 338 is started to fix the insulating film strip 530. At this time, the cutting mechanism 340 cuts the insulating film strip 530 to obtain the insulating film strip 530. In this way, it can be ensured that when the insulating film strip 530 is cut, the insulating film strip 530 will not retract backwards under the action of the heavy hammer, and there is no need to realize the fixing function while realizing the punching function through the punching mechanism 330.

[0053] like Figure 5 As shown, in the embodiment of the utility model, the film placing platform 360 includes a film joining platform 361, and a limiting plate 3611 and an adjusting plate 3612 are provided on the film joining platform 361. A limiting groove for the insulating film strip 530 to pass through is formed between the limiting plate 3611 and the adjusting plate 3612, and the adjusting plate 3612 can approach / move away from the limiting plate 3611. The limiting groove can constrain the position of the insulating film strip 530 to prevent the insulating film strip 530 from being offset, and the width of the limiting groove can be changed by adjusting the position of the adjusting plate 3612, so as to ensure that the film joining platform 361 can meet the needs of insulating film strips 530 of different widths, thereby improving applicability.

[0054] Based on the improvement of the above embodiment, the film placing platform 360 includes a film pressing assembly 362, which is used to constrain the insulating film strip 530 on the limiting groove. The film pressing assembly 362 can further ensure the position accuracy of the insulating film strip 530 and avoid the deviation of the insulating film strip 530. Specifically, when the film pulling mechanism 350 releases the insulating film strip 530 on the film placing platform 360, the insulating film strip 530 adheres to the film pulling mechanism 350 due to its own viscosity or the influence of factors such as clamping deformation, resulting in the inability of the film pulling mechanism 350 to effectively release the insulating film strip 530. The film pressing assembly 362 constrains the insulating film strip 530 on the limiting groove before the film pulling mechanism 350 releases the insulating film strip 530, ensuring that the position of the insulating film strip 530 does not deviate.

[0055] In addition, if Figure 5-Figure 6 As shown, the insulating film strip 530 placed on the same film connection platform 361 is composed of a plurality of film strip units. By arranging the insulating film strip 530 into a plurality of film strip units, the film sticking size of the insulating film strip 530 can be ensured, and the film sticking effect of the insulating film strip 530 can be improved.

[0056] It should be noted that there are two ways to punch the insulating film strip 530:

[0057] First, the punching action is completed in one go. This method can effectively ensure the dimensional accuracy of the penetration area 531 of the insulating film strip 530. However, it is necessary to set a sufficient number of punches 332 on the punching mechanism 330, which will directly lead to an increase in the size of the punching mechanism 330, increase the manufacturing cost and the large floor space occupied by the equipment.

[0058] Secondly, the punching action is completed multiple times, by setting a small-sized punching mechanism 330, punching a small amount of the through-area 531 each time, and completing the punching multiple times, that is, the insulating film strip 530 is pulled once each time the punching action is completed, until the punching of the entire insulating film strip 530 is completed. However, each time the insulating film strip 530 is pulled, a certain error will be generated. After multiple pulling, the accumulated error is large, which will directly lead to the position of the through-area 531 punched later not corresponding to the welding strip 520.

[0059] Therefore, by arranging the insulating film strip 530 placed on the same film receiving station 361 into multiple film strip units, the size problem of the punching mechanism 330 and the problem of the processing cumulative error of the insulating film strip 530 can be effectively avoided. In addition, the number of penetration areas 531 on the film strip unit is an integer multiple of the number of punches 332, preferably 1 or 2 times, which facilitates the production of the penetration areas 531 on the film strip unit and ensures the dimensional accuracy requirements of the penetration areas 531.

[0060] like Figure 6 As shown, in the embodiment of the utility model, the film supply mechanism 300 includes a detection platform 363, which is located between the cutting mechanism 340 and the film placing platform 360, and a monitor 3631 is installed on the detection platform 363. The monitor 3631 can monitor the presence or absence of the insulating film strip 530, which can effectively prevent the equipment from running empty. The monitor 3631 here is preferably a photoelectric switch.

[0061] It is necessary to add that, if Figure 2-Figure 3 As shown, in the utility model, two film roll mechanisms are provided for providing insulating film strips 530 to the same film connection station 361. When one of them is in working state, the other film roll mechanism is in standby state. When the monitor 3631 detects that there is no material, the standby film roll mechanism is started. In this way, the two film roll mechanisms can be switched according to the operating conditions of the equipment to realize continuous operation of the equipment.

[0062] In the embodiment of the utility model, the film-laying mechanism 400 includes a film-taking assembly 410, a first drive 430, a second drive 440, a heat welding assembly 420, and a correction assembly 450. The film-taking assembly 410 is installed at the output end of the first drive 430, and the heat welding assembly 420 is installed on the film-taking assembly 410. When the first drive 430 is working, it can drive the film-taking assembly 410 to perform a longitudinal translation movement. The second drive 440 is used to drive the film-taking assembly 410 and the first drive 430 to perform a lateral translation movement. Here, the first drive 430 and the second drive 440 are conventional drive assemblies, please refer to Fig.10 , the utility model will not elaborate on its specific structure and working method. In addition, the correction component 450 is used to obtain the position information of the penetration area 531 on the insulating film strip 530 and the position information of the welding strip 520 on the battery string group 510, and adjust the position of the insulating film strip 530 based on the position information of the welding strip 520 and the position information of the penetration area 531, so that the position of the welding strip 520 overlaps with the position of the penetration area 531. In this way, through the cooperation of the various components of the film-laying mechanism 400, it can be ensured that the penetration area 531 of the insulating film strip 530 overlaps with one of the first electrode area and the second electrode area, thereby ensuring the accuracy of the film-sticking position. Among them, the film-taking component 410 is preferably a vacuum adsorption component; the hot welding component 420 is preferably a hot air pipe 421 melting heat structure.

[0063] In the above embodiment, if Fig.11 As shown, the calibration component 450 includes a camera component 451 and a third drive 452. The film taking hand 411 on the film taking component 410 is installed at the output end of the third drive 452. The third drive 452 is used to drive the film taking hand 411 and the heat welding component 420 to move along the length direction of the insulating film strip 530. The camera component 451 is installed at the output end of the first drive 430. The camera component 451 is installed at the output end of the first drive 430. The camera component 451 can be mutually converted between the film taking position and the film placing position through the second drive 440, and then the position information of the penetration area 531 on the insulating film strip 530 and the position information of the welding strip 520 on the battery string group 510 can be obtained by installing a small number of camera components 451, thereby reducing the manufacturing cost of the equipment. In addition, the film removing hand 411 is installed at the output end of the third drive 452. The third drive 452 can drive the film removing hand 411 and the hot welding assembly 420 to move along the length direction of the insulating film strip 530. That is, when there is a deviation between the position of the welding strip 520 and the position of the penetration area 531, the deviation is corrected by adjusting the position of the film removing hand 411 to ensure that the position of the welding strip 520 overlaps with the position of the penetration area 531.

[0064] In addition, a reflector 3613 is added in the limiting groove on the film-laying mechanism 400. The reflector 3613 can enhance the recognition of the position of the penetration area 531 on the insulating film strip 530 by the camera component 451, thereby improving the accuracy of the camera component 451 in obtaining the position information of the penetration area 531.

[0065] In addition, the correction component 450 also includes a light source 460, which is used to adjust the brightness of the area where the position information is obtained. When obtaining the position information of the penetration area 531 on the insulating film strip 530, the position brightness of the penetration area 531 of the insulating film strip 530 is increased, thereby improving the accuracy of the camera component 451 in obtaining the position information of the penetration area 531; when obtaining the position information of the welding strip 520 on the battery string group 510, the position brightness of the welding strip 520 is increased, thereby improving the accuracy of the camera component 451 in obtaining the position information of the welding strip 520.
