Abstract
Description
Technical Field
[0001] The present application relates to the technical field of photovoltaic module production, and in particular to a film laying mechanism and a film cutting and laying device. Background Art
[0002] Photovoltaic modules refer to photovoltaic cell modules that are composed of one or two substrates (such as tempered glass), adhesive films (such as EVA films, etc.) and solar cells, which are laminated at high temperature in a laminator to form a composite layer, and the cells are connected in series and parallel by wires to the lead ends. In the process of manufacturing photovoltaic modules, adhesive films need to be laid on the tempered glass so that the tempered glass and solar cells can be bonded and fixed. Since the adhesive film is generally in the form of a roll, it is necessary to cut the adhesive film into a size suitable for the tempered glass, and then punch holes on the adhesive film for the lead wires to pass through, and lay the cut and punched adhesive film on the tempered glass.
[0003] The existing film laying mechanism generally moves as a whole and descends to the grabbing position under the drive of the XYZ axis lifting servo, uses the negative pressure of the suction cup to absorb the film and rise to a safe height, then moves horizontally to the top of the tempered glass, and then descends to the discharge position, and finally the negative pressure of the suction cup is opened, so as to complete the laying of the film on the tempered glass. However, since the film material of different batches and different manufacturers cannot be guaranteed to be exactly the same, some batches of film have a rougher surface and therefore have a larger particle size. When using the suction cup to absorb such rough film, the film will frequently fall off. To avoid this, it is necessary to frequently stop the machine and replace the suction cup according to the different batches of film, which will greatly reduce production efficiency.

[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.
[0032] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0033] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0034] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0035] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0036] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.
[0037] As described in the background technology, in the process of manufacturing photovoltaic modules, it is necessary to lay an adhesive film on the substrate (such as tempered glass) so that the tempered glass and the solar cell can be bonded and fixed. The existing adhesive film laying mechanism generally moves as a whole and descends to the grabbing position under the drive of the XYZ axis lifting servo, uses the negative pressure of the suction cup to absorb the adhesive film and rise to a safe height, then moves horizontally as a whole to the top of the tempered glass, and then descends to the discharge position, and finally the negative pressure of the suction cup is opened, thereby completing the laying of the adhesive film on the tempered glass.
[0038] However, since the film materials of different batches and different manufacturers cannot be guaranteed to be exactly the same, the surface of some batches of film is relatively rough, so the particle size is large. When using the suction cup to absorb this rough film, the film will frequently fall off. To avoid this, it is necessary to frequently stop the machine and replace the suction cup according to the different film batches. Specifically, each device has about three film falls per day, and each manual processing takes 3 minutes, or in order to avoid this, each device takes 30 minutes to replace the suction cup each time, resulting in a significant reduction in production efficiency.
[0039] To this end, the present application provides a film laying mechanism and a film cutting and laying device including the film laying mechanism, which is used to lay the film on a substrate using the film laying mechanism so that the substrate can be bonded and fixed to the battery cell, thereby preparing a photovoltaic module.
[0040] The following takes the application of the adhesive film laying mechanism in the adhesive film cutting and laying equipment for preparing photovoltaic modules as an example to explain at least part of the structure of the above-mentioned adhesive film cutting and laying equipment and the structure of the adhesive film laying mechanism. It can be understood that in other embodiments, the adhesive film laying mechanism of the present application is not limited to being used in the adhesive film cutting and laying equipment for preparing photovoltaic modules, and can also be used in any equipment that needs to lay an adhesive film on a substrate, which is not limited here.
[0041] like Figure 1 As shown, it is a schematic diagram of a film cutting and laying device 10 provided in one embodiment of the present application. The film cutting and laying device 10 provided in one embodiment of the present application comprises a film feeding mechanism 100, a substrate feeding mechanism 200 and a film laying mechanism 300, wherein the film feeding mechanism 100 has a film grabbing station 101, which is used to transport the film 40 to the film grabbing station 101 along a second horizontal direction (the Y direction shown in the figure); the substrate feeding mechanism 200 has a film laying A station 102 is provided, which is used to transport the substrate 50 to the film laying station 102 along a first horizontal direction (X direction shown in the figure) perpendicular to the second horizontal direction; the film laying mechanism 300 is arranged above the film feeding mechanism 100 or the substrate feeding mechanism 200, and it can move back and forth between the film grabbing station 101 and the film laying station 102 to clamp the film 40 at the film grabbing station 101, and lay the film 40 on the substrate 50 at the film laying station 102.
[0042] exist Figure 1 In the illustrated embodiment, the film feeding mechanism 100 and the substrate feeding mechanism 200 are staggered in the vertical direction (Z direction shown in the figure), that is, the film feeding mechanism 100 and the substrate feeding mechanism 200 are perpendicular to each other, and the film feeding mechanism 100 is located above the substrate feeding mechanism 200, so that the space in the vertical direction can be fully utilized, thereby saving the space occupied by the entire film cutting and laying device 10 in the horizontal direction. Of course, it can be understood that the film feeding mechanism 100 and the substrate feeding mechanism 200 can be located at the same height in the vertical direction and arranged in parallel, which is not limited here.
[0043] In an optional embodiment, the film cutting and laying equipment 10 also includes a film cutting mechanism (not shown in the figure), which is arranged above the film feeding mechanism 100 and has a cutter. When the film feeding mechanism 100 conveys the film 40 to the film grabbing station 101, the cutter can move back and forth in the vertical direction to cut the long strip of film 40 into the required length for clamping by the film laying mechanism 300.
[0044] For details on the structure of the adhesive film laying mechanism 300, see Figures 2 to 4The adhesive film laying mechanism 300 includes a bracket 310, a first clamping assembly 320 and a second clamping assembly 330, wherein the bracket 310 is formed by splicing a plurality of profiles, and the profiles can be aluminum alloy profiles or stainless steel profiles. Since the aluminum alloy material has the characteristics of light weight, high strength and low cost, the profiles are preferably aluminum alloy profiles. The first clamping assembly 320 and the second clamping assembly 330 are respectively arranged at the opposite ends of the bracket 310 in the first horizontal direction. The bracket 310 can be driven by a servo motor to controllably drive the first clamping assembly 320 and the second clamping assembly 330 to move in the first horizontal direction, the second horizontal direction and the vertical direction respectively. And the first clamping assembly 320 and the second clamping assembly 330 each include a plurality of clamping claws 321 arranged at intervals along the second horizontal direction, and the clamping claws 321 of the first clamping assembly 320 and the clamping claws 321 of the second clamping assembly 330 are respectively used to clamp the edges of the adhesive film 40 at the opposite ends in the first horizontal direction. In the embodiment shown in the figure, the first clamping assembly 320 and the second clamping assembly 330 each include five clamping claws 321. It is understandable that in other embodiments, the number of clamping claws 321 of the first clamping assembly 320 and the second clamping assembly 330 can be any number, which is not limited here.
[0045] Furthermore, in order to clamp the two end edges of the adhesive film 40 and avoid wrinkling the adhesive film 40, the first clamping assembly 320 and the second clamping assembly 330 can be controlled to move closer to or farther from each other. Figure 1 As shown, the film feeding mechanism 100 has a bottom plate 110 for carrying the film 40 , and two ends of the bottom plate 110 are respectively provided with avoidance holes 110 a for the clamping claws 321 to pass through. In this way, when the film laying mechanism 300 moves as a whole to the film grabbing station 101 (that is, when the bracket 310 drives the first clamping component 320 and the second clamping component 330 to move to the film grabbing station 101), the clamping jaw 321 of the first clamping component 320 and the clamping jaw 321 of the second clamping component 330 can descend and pass through the avoidance hole 110a, and then the clamping jaw 321 of the first clamping component 320 and the clamping jaw 321 of the second clamping component 330 can approach each other to clamp the edge of the film 40; when the film laying mechanism 300 performs the overall ascending, translating and descending action to move to the film laying station 102, the clamping jaw 321 of the first clamping component 320 and the clamping jaw 321 of the second clamping component 330 can release the film 40 and move away from each other, so that the film 40 can fall and be laid on the substrate 50.
[0046] In one embodiment, the movement of the first gripping assembly 320 and the second gripping assembly 330 is driven by the first drive cylinder 340 and the second drive cylinder 350, respectively. Figure 2 and Figure 3There are two first drive cylinders 340, and the two first drive cylinders 340 are arranged at one end of the bracket 310 in the first horizontal direction and are spaced apart along the second horizontal direction; there are also two second drive cylinders 350, and the two second drive cylinders 350 are arranged at the other end of the bracket 310 in the first horizontal direction and are also spaced apart along the second horizontal direction. The first drive cylinder 340 is connected to the first clamping assembly 320, and is used to drive the first clamping assembly 320 to move along the first horizontal direction; the second drive cylinder 350 is connected to the second clamping assembly 330, and is used to drive the second clamping assembly 330 to move along the first horizontal direction. It can be understood that the first drive cylinder 340 and the second drive cylinder 350 can be cylinders, hydraulic cylinders, electric cylinders, etc., and the number of the first drive cylinder 340 and the second drive cylinder 350 is not particularly limited.
[0047] More specifically, the first clamping assembly 320 and the second clamping assembly 330 have the same structure, and are spaced and symmetrically arranged in the first horizontal direction. Figure 2 and Figure 3 As shown, the first clamping assembly 320 and the second clamping assembly 330, in addition to respectively including a plurality of clamping claws 321, also respectively include a connecting beam 322 arranged along the second horizontal direction. The connecting beam 322 can also be an aluminum alloy profile or a stainless steel profile, wherein the connecting beam 322 of the first clamping assembly 320 is connected to the output end 3212b of the first driving cylinder 340, and the connecting beam 322 of the second clamping assembly 330 is connected to the output end 3212b of the second driving cylinder 350. The clamping claws 321 of the first clamping assembly 320 and the clamping claws 321 of the second clamping assembly 330 are respectively arranged on the corresponding connecting beams 322. Specifically, the plurality of clamping claws 321 are arranged at intervals corresponding to the extension direction of the connecting beam 322.
[0048] See also Figure 5, is a schematic diagram of a clamping jaw 321 provided in an embodiment of the present application. In this embodiment, the clamping jaw 321 includes a support frame 3211, a third driving cylinder 3212 and a clamping plate 3213, wherein the support frame 3211 is mounted on the connecting beam 322, and the support frame 3211 is formed by bending a sheet metal, so that the support frame 3211 forms a accommodating chamber 3211a with a side opening inside itself. The third driving cylinder 3212 has a fixed end 3212a and an output end 3212b arranged opposite to each other, the fixed end 3212a is mounted on the top wall of the accommodating chamber 3211a, the clamping plate 3213 is connected to the output end 3212b, and the side of the clamping plate 3213 away from the third driving cylinder 3212 is formed with a first clamping surface 321a, and the bottom wall of the accommodating chamber 3211a is formed with a second clamping surface 321b, and the first clamping surface 321a and the second clamping surface form a clamping gap 321c for clamping the edge of the adhesive film 40. The third driving cylinder 3212 may also be a cylinder, a hydraulic cylinder or an electric cylinder, etc., and under the drive of the third driving cylinder 3212, the clamping plate 3213 can move in the vertical direction, so as to be close to or away from the bottom wall of the accommodating cavity 3211a, so that the first clamping surface 321a and the second clamping surface 321b can be close to or away from each other. When the first clamping surface 321a and the second clamping surface 321b are close to each other, the edge of the adhesive film 40 can be clamped by the first clamping surface 321a and the second clamping surface 321b in the clamping gap 321c; when the first clamping surface 321a and the second clamping surface 321b are away from each other, the edge of the adhesive film 40 can be loosened, so that the adhesive film 40 can fall under the action of gravity and be laid on the substrate 50 below.
[0049] It should be noted that in the above embodiment, the first driving cylinder 340 drives the first clamping assembly 320 to translate, the second driving cylinder 350 drives the second clamping assembly 330 to translate, so as to complete the telescopic action of the first clamping assembly 320 and the second clamping assembly 330, and the third driving cylinder 3212 drives the clamping plate 3213 to translate, so as to complete the clamping action, which is controlled by setting an electromagnetic valve in the control circuit.
[0050] Thus, through the above arrangement, when the adhesive film 40 is clamped by the clamping jaws 321, the two opposite sides of its edge are respectively attached to the first clamping surface 321a and the second clamping surface 321b, so that there is a larger contact area between the edge of the adhesive film 40 and the clamping jaws 321. Compared with the method of simply adsorbing the adhesive film 40 by the suction cup in the prior art, no matter what batch the adhesive film 40 is from or how rough the adhesive film 40 is, during the whole process of transferring the adhesive film 40 from the adhesive film grabbing station 101 to the adhesive film laying station 102, it can be ensured that the adhesive film 40 is firmly clamped in the clamping gap 321c and will not fall off the clamping jaws 321, and there is no need to frequently replace the clamping jaws 321, which effectively improves the production efficiency.
[0051] As a further improvement to the above embodiment, please continue to refer to Figure 5 , a buffer plate 3214 is also provided on the inner wall of the support frame 3211 and is arranged opposite to the clamping plate 3213. The materials of the buffer plate 3214 and the clamping plate 3213 are both soft silicone materials. At this time, the side surface of the buffer plate 3214 facing the clamping plate 3213 serves as the bottom wall of the accommodating cavity 3211a to form the second clamping surface 321b. By providing the buffer plate 3214 and selecting the materials of the buffer plate 3214 and the clamping plate 3213 as soft silicone materials, the first clamping surface 321a and the second clamping surface 321a are both soft elastic surfaces. When the edge of the adhesive film 40 is clamped in the clamping gap 321c, the contact with the first clamping surface 321a and the second clamping surface 321b is soft contact rather than contact, which effectively protects the adhesive film 40 and prevents the adhesive film 40 from being damaged when being clamped.
[0052] Of course, it is understandable that in other embodiments, the buffer plate 3214 is not limited to being provided on the inner wall of the support frame 3211, but a groove is provided on the bottom wall of the support frame 3211, and a soft silicone material is embedded in the groove by gluing, and one side surface of the soft silicone material is used as the second clamping surface 321b. As long as the first clamping surface 321a and the second clamping surface 321b are both soft elastic surfaces, no limitation is made here.
[0053] It should be noted that the specific structure of the clamping jaw 321 is not limited to the structure described in the above embodiment, as long as it has a first clamping surface 321a and a second clamping surface 321b that are arranged opposite to each other in the vertical direction and can approach or move away from each other.
[0054] In addition, in order to ensure that the adhesive film 40 can be accurately laid at the corresponding position on the substrate 50, a visual inspection device is also provided on the bracket 310. In some embodiments, the visual inspection device includes one or more industrial vision cameras, which are used to perform defect detection on the adhesive film 40 when the clamp 321 clamps the edge of the adhesive film 40, and to guide the bracket 310, the first clamping component 320 and the second clamping component 330 to move to a preset position together, so that the adhesive film 40 can be accurately laid at the corresponding position on the substrate 50, avoiding deviations in the laying position of the adhesive film 40 and affecting the final quality of the photovoltaic module.
[0055] In summary, the adhesive film laying mechanism 300 and the adhesive film cutting and laying equipment 10 including the adhesive film laying mechanism 300 provided in the present application, by utilizing the clamp 321 to grab the adhesive film 40, can ensure stable grabbing without falling when grabbing the adhesive film 40 from different manufacturers or different batches, thereby reducing manual intervention, and making the one-time success rate of grabbing and laying the adhesive film 40 close to 100%, thereby effectively improving the production efficiency and finished product qualification rate of photovoltaic module products.
[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
