Description

Technical Field

[0001] The utility model relates to the technical field of reflective film cutting, in particular to a cutting mechanism and reflective film automatic attaching equipment. Background Art

[0002] At present, for the sake of green living and sustainable development, new energy technologies are constantly developing, the demand for photovoltaic modules has greatly increased, and the competition among factories producing photovoltaic modules is becoming increasingly fierce. In order to gain higher competitiveness in the market, on the one hand, it is necessary to reduce the production cost of manufacturing photovoltaic modules, and on the other hand, it is necessary to improve the performance of photovoltaic modules.

[0003] In order to solve the problem of low sunlight utilization rate in photovoltaic modules in the prior art, the sunlight between the gaps between the cells is reused to increase the power of the photovoltaic panel. There are currently two main methods for this: gap film lamination process and white glaze glass. Gap film lamination process: usually a hot melt adhesive reflective film tape is attached to the glass and the photovoltaic back panel to achieve sunlight reflection between the gaps between the cells, which is beneficial to improve the power of existing double-glass module products. White glaze glass: the semi-tempered glass of the photovoltaic back panel is replaced with white glaze glass to achieve sunlight reflection between the gaps between the cells. Among them, the cost of the gap film lamination process is lower than that of white glaze glass, which can improve the power and load capacity of photovoltaic panels, reduce costs and increase efficiency of photovoltaic modules, and improve product competitiveness.

[0004] However, the hot melt adhesive reflective film tape itself is made of a relatively soft material and has a long attachment length. Manual attachment is difficult to operate and has a low attachment flatness, which cannot achieve a higher utilization rate of sunlight. Nowadays, automatic reflective film attachment equipment is usually used to attach hot melt adhesive reflective film tape to photovoltaic back panels. The film attachment head is responsible for attachment and cutting. After attachment, the cutting mechanism in the film attachment head automatically cuts off the hot melt adhesive reflective film tape. In order to improve production efficiency, the reflective film attachment equipment needs to complete 10-24 reflective film attachment tasks at the same time, so 10-24 sets of film attachment heads are required in a row. The smaller the size of the film attachment head, the smaller the size of the equipment. However, the overall size of the cutting mechanism in the prior art is relatively large, resulting in a larger size of the film attachment head, which is not conducive to reducing the size of the equipment and saving space in the production plant.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0033] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0034] Combination Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a cutting mechanism for shearing a reflective film 26 in an automatic reflective film attaching device 2. The cutting mechanism 1 comprises: a lifting and moving device 11, a first mounting block 12 and a shearing assembly 13. The lifting and moving device 11 and the first mounting block 12 are fixed to the automatic reflective film attaching device 2; the shearing assembly 13 comprises a first cutter 131 and a second cutter 132. The first cutter 131 is fixedly arranged on the first mounting block 12, one end of the second cutter 132 is hinged to one end of the first cutter 131, the output end of the lifting and moving device 11 is connected to the other end of the second cutter 132, and the lifting and moving device 11 can drive the second cutter 132 to move toward the first cutter 131 for shearing.

[0035] In this embodiment, the cutting mechanism 1 is arranged at the front end position where the reflective film 26 is attached to the photovoltaic back panel. After the reflective film 26 is transported to the attachment position, the reflective film 26 is cut by the cutting mechanism 1. When the reflective film 26 needs to be cut, the lifting and moving device 11 starts to work and drives its output end to perform lifting and lowering movements. Since the other end of the second cutter 132 is connected to the output end of the lifting and moving device 11, the second cutter 132 will move accordingly. Since one end of the second cutter 132 is hinged to one end of the first cutter 131, and the first cutter 131 is fixedly arranged on the first mounting block 12 by the fixing member 16, when the second cutter 132 moves, the second cutter 132 performs a shearing movement and an opening movement unidirectionally toward the first cutter 131, thereby achieving shearing of the reflective film 26.

[0036] In this embodiment, shearing motion refers to the process of applying a relative motion on the contact surface through two or more workpieces that are parallel or relative to each other, thereby achieving cutting, shearing, cutting and the like. In mechanics, shearing usually refers to a stress state, that is, a stress state generated when two parallel forces act in opposite directions on a plane or line of an object that is parallel to the two forces. When the lifting and moving device 11 in this embodiment starts working, it drives the second cutter 132 to perform lifting and lowering motion. Since one end of the second cutter 132 is hinged to the first cutter 131, when the second cutter 132 performs lifting and lowering motion, it performs shearing motion relative to the first cutter 131. When the sharp edge of the second cutter 132 contacts the sharp edge of the first cutter 131, the relative motion between them will form a shearing force, thereby cutting the reflective film 26 located between the two.

[0037] See also Figure 1 As shown, in one embodiment, it also includes a first connecting block 14, on which an arc groove 141 is opened, the output end of the lifting and moving device 11 is slidably connected in the arc groove 141, and the other end of the second cutter 132 is fixedly connected to the first connecting block 14; the inner arc direction of the arc groove 141 is the same as the shearing direction of the second cutter 132.

[0038] In this embodiment, the movement path of the lifting and moving device 11 is a straight line, and the shearing path of the second cutter 132 is an arc. In order to enable the lifting and moving device 11 to drive the second cutter 132 to shear, a first connecting block 14 is added between the output end of the lifting and moving device 11 and the second cutter 132; so that the lifting and moving device 11 also moves relatively in the arc groove 141 on the first connecting block 14 when moving in a straight line. Due to the design of the arc groove 141, the driving direction of the lifting and moving device 11 is converted from a straight line to an arc motion of the first connecting block 14, thereby linking the second cutter 132 to perform an arc motion, so as to realize the shearing movement of the second cutter 132 toward the first cutter 131.

[0039] In one embodiment, a connecting member 15 is disposed at the output end of the lifting and moving device 11 , and the output end of the lifting and moving device 11 is slidably connected to the arc groove 141 through the connecting member 15 .

[0040] In this embodiment, the connecting member 15 is a pin 151 and a stop pin 152. The pin 151 connects the output end of the lifting and moving device 11 to the arc groove 141 by sliding, and then the stop pin 152 is inserted into the end of the pin 151 to limit the pin 151 from falling off during the sliding process. Specifically, when the lifting and moving device 11 is lifted and lowered, the pin 151 cooperates with the first connecting block 14, so that the lifting and moving device 11 can move along the arc path of the arc groove 141.

[0041] In one embodiment, the lifting and moving device 11 includes a driving structure having a linear driving function.

[0042] In this embodiment, the driving structure with linear driving function can adopt a screw transmission device or a lifting cylinder. In this embodiment, the lifting cylinder is preferably used. Since the lifting cylinder has a simple structure and a small size, it can save installation space and reduce the size of the cutting mechanism 1.

[0043] See also Figure 2 to Figure 7 As shown, the embodiment of the utility model also provides a reflective film automatic attaching device, which includes: a substrate 25 and a conveying mechanism 21, a clamping movable mechanism 22, a pressing mechanism 23 and the cutting mechanism 1 as described above, which are installed on the substrate 25; the conveying mechanism 21 is used to convey the reflective film 26 to the clamping movable mechanism 22, and the clamping movable mechanism 22 clamps the reflective film 26 and moves it toward the pressing mechanism 23 for conveyance; the pressing mechanism 23 is used to press the reflective film 26 down and tightly adhere it to a photovoltaic backboard pre-configured on the bottom of the reflective film 26; the cutting mechanism 1 is located between the clamping movable mechanism 22 and the pressing mechanism 23.

[0044] In this embodiment, for the convenience of understanding, the conveying and attaching process of the reflective film 26 can be as follows: the reflective film 26 will pass through the clamping moving mechanism 22 under the drive of the conveying mechanism 21, and after the clamping moving mechanism 22 clamps and fixes the reflective film 26, it drives the reflective film 26 to move toward the attaching position attached to the photovoltaic backboard, that is, the pressing position of the pressing mechanism 23, and the pressing mechanism 23 presses the reflective film 26 down to the photovoltaic backboard (not shown in the figure) pre-configured at the bottom of the pressing mechanism 23, so that the reflective film 26 is attached to the photovoltaic backboard; at this time, the reflective film 26 at the position of the pressing mechanism 23 The reflective film 26 is clamped and fixed between the pressing mechanism 23 and the photovoltaic backboard, and then the clamping and moving mechanism 22 releases the reflective film 26 and moves to the initial position. It should be noted that after the clamping and moving mechanism 22 moves to the initial position, the reflective film 26 is not clamped and fixed, and the clamping and moving mechanism 22 is kept in the state of releasing the reflective film 26; further, the entire reflective film automatic attaching device 2 is driven to move by the front end transverse movement mechanism (not shown in the figure), and the moving stroke is the length of the reflective film 26 that needs to be attached to the photovoltaic backboard, and the length can be reasonably set according to actual needs. After the film is attached, the clamping and moving mechanism 22 clamps and fixes the reflective film 26, and then the reflective film 26 is cut by the cutting mechanism 1, and finally the pressing mechanism 23 is controlled to lift up and move to the initial position, thereby completing the attaching work of the reflective film 26. If it is necessary to continue to attach the reflective film 26 to the next photovoltaic back panel, the reflective film 26 is again transported toward the bottom of the pressing mechanism 23 under the drive of the clamping moving mechanism 22, and this cycle is repeated to achieve automatic attachment of the reflective film 26.

[0045] In this embodiment, a notch is provided at the bottom of the substrate 25, and the first mounting block 12 of the cutting mechanism 1 is arranged in the notch, so that the shearing component 13 is installed in the notch, thereby reducing the space occupied by the installation of the shearing component 13, and the lifting and moving device 11 of the cutting mechanism 1 is installed on the substrate 25 and is located above the shearing component 13, so that the lifting and moving device 11 and the shearing component 13 are arranged in the same direction, thereby reducing the volume of the cutting mechanism 1, which is beneficial to reducing the size of the film sticking head of the reflective film automatic sticking equipment 2, reducing the overall size of the equipment and saving space in the production plant.

[0046] In one embodiment, a heating component 24 is further included. The heating component 24 is disposed at the bottom of the substrate 25. The heating position of the heating component 24 is located at the bottom of the pressing mechanism 23 to heat the reflective film 26 attached to the photovoltaic back panel.

[0047] In this embodiment, since the reflective film 26 is non-sticky, it will not stick to the clamping movable mechanism 22 when the clamping movable mechanism 22 clamps the reflective film 26. When the reflective film 26 at the bottom of the pressing mechanism 23 is heated by the heating component 24, the reflective film 26 becomes sticky after being heated. Then, the pressing mechanism 23 is moved downward to press the reflective film 26 onto the photovoltaic backboard. At this time, the reflective film 26 becomes sticky, so that the reflective film 26 can be stuck to the photovoltaic backboard.

[0048] In a more specific embodiment, the heating assembly 24 includes an adjusting block 241, a second mounting block 244, a heating rod 243, a second connecting block 245, a heat conduction block 246 and an air pipe joint 242. The adjusting block 241 is installed on one side of the substrate 25, the second mounting block 244 is connected to the adjusting block 241, the heating rod 243 is passed through the second mounting block 244, the second connecting block 245 is fixed at one end of the heating rod 243, the heat conduction block 246 is fixed on the second connecting block 245 and is connected to the heating rod 243, and the air pipe joint 242 is arranged at the other end of the heating rod 243 and is connected to the heating rod 243.

[0049] In this embodiment, the heating rod 243 takes in air through the air pipe joint 242, and the air is heated in the heating rod 243 and then blown out through the heat conduction block 246. The opening of the heat conduction block 246 faces the bottom of the pressing mechanism 23, so that the hot air blown out by the heat conduction block 246 is blown onto the reflective film 26, so that the reflective film 26 becomes sticky due to the heat. Among them, the adjustment block 241 can adjust the position on the substrate 25, thereby driving the heating rod 243 and the heat conduction block 246 to adjust the position relative to the pressing mechanism 23, so that the outlet of the heat conduction block 246 corresponds to the bottom of the pressing mechanism 23.

[0050] See also Figure 2 and Figure 4 As shown, in one embodiment, the conveying mechanism 21 includes a plurality of guide wheels 212 and a sliding assembly 211, wherein one of the guide wheels 212 is mounted on the sliding assembly 211 and can move along the up and down directions of the substrate 25 to adjust the tightness of the reflective film 26, and the other guide wheels 212 are mounted on the top and bottom of the substrate 25, and the reflective film 26 is sleeved on the plurality of guide wheels 212.

[0051] In this embodiment, the sliding assembly 211 includes a slider 2111 and a slide rail 2112. The slide rail 2112 is arranged on the substrate 25 along the up and down direction of the substrate 25. The substrate 25 is provided with a slideway opening 251 at a position corresponding to the slide rail 2112. The slider 2111 is slidably mounted on the slide rail 2112 and is located in the slideway opening 251. One guide wheel 212 is mounted on the slider 2111, and the other guide wheels 212 are mounted on the top and bottom of the substrate 25. The reflective film 26 is sleeved on the plurality of guide wheels 212. When the clamping moving mechanism 22 clamps the reflective film 26 toward the pressing mechanism 23, the reflective film 26 is moved downward. When moving, the reflective film 26 will drive the multiple guide wheels 212 to rotate so that the reflective film 26 can move forward; when the clamping moving mechanism 22 drives the reflective film 26 to move forward for a long time, it will cause the reflective film 26 to become tight or loose. When the reflective film 26 is tight, it drives the guide wheels 212 installed on the slider 2111 to move toward the top of the substrate 25, thereby improving the tightness of the reflective film 26. When the reflective film 26 is loose, it drives the guide wheels 212 installed on the slider 2111 to move toward the bottom of the substrate 25 to improve the looseness of the reflective film 26.

[0052] See also Figure 3 and Figure 6 As shown, in one embodiment, the conveying mechanism 21 also includes a detection component for detecting the tightness of the reflective film 26, and the detection component includes two sensors 27 and a sensor sheet 28. The sensor sheet 28 is installed on a slider 2111 in the sliding component 211, and the two sensors 27 are installed on the substrate 25 and are respectively located at opposite ends of the sliding direction of the sliding component 211.

[0053] In this embodiment, when the slider 2111 slides to the top and bottom of the slideway opening 251, the sensor sheets 28 on the slider 2111 will trigger the two sensor sheets 28 respectively, indicating that the slider 2111 has slid to the extreme position. At this time, the slider 2111 fails to adjust the tightness of the reflective film 26. The unwinding speed of the reflective film 26 is adjusted by an external unwinding motor (not shown in the figure). When the slider 2111 is at the top position of the slideway opening 251, the top sensor 27 is triggered, the speed of the unwinding motor is increased, and the reflective film 26 is unwound quickly to improve the reflective film 26 being too tight. When the slider 2111 is at the bottom position of the slideway opening 251, the bottom sensor 27 is triggered, the speed of the unwinding motor is reduced, and the unwinding is slow or paused to improve the reflective film 26 being too loose.

[0054] See also Figure 2 to Figure 5 As shown, in one embodiment, the clamping movement mechanism 22 includes a first driving member 221 and a clamping assembly 222. The first driving member 221 is disposed on the substrate 25. The clamping assembly 222 is connected to the output end of the first driving member 221 and is used to clamp the reflective film 26. The driving direction of the first driving member 221 is toward the cutting mechanism 1.

[0055] The clamping assembly 222 includes a fixed block 2221, a sandwich plate 2223 and a clamping member 2222; the fixed block 2221 is arranged at the output end of the first driving member 221, the sandwich plate 2223 is arranged on the fixed block 2221, a guide channel for the reflective film 26 to pass through is provided in the sandwich plate 2223, and the clamping member 2222 is arranged on the fixed block 2221, and the clamping member 2222 can move telescopically and can be pressed into the guide channel to compress the reflective film 26.

[0056] In this embodiment, when the reflective film 26 is transported to the position of the clamping assembly 222 through the conveying mechanism 21, the clamping assembly 222 can clamp the reflective film 26 and move toward the pressing mechanism 23 under the drive of the first driving member 221. At the same time, the reflective film 26 follows the clamping and moving mechanism 22 to move to the bottom of the pressing mechanism 23, so that the pressing mechanism 23 can press the reflective film 26 down onto the photovoltaic backplane pre-configured at the bottom of the pressing mechanism 23.

[0057] Specifically, the sandwich plate 2223 has a guide channel for the reflective film 26 to pass through. The sandwich plate 2223 is located below the clamping member 2222. A avoidance opening is opened on the side of the sandwich plate 2223 close to the clamping member 2222. The avoidance opening is connected to the guide channel of the sandwich plate 2223, so that the reflective film 26 is exposed through the avoidance opening. The output end of the clamping member 2222 faces the avoidance opening. When the clamping member 2222 moves toward the sandwich plate 2223, it can extend into the sandwich plate 2223 through the avoidance opening. The clamping member 2222 cooperates with the sandwich plate 2223 to clamp the reflective film 26. Therefore, when the clamping member 2222 clamps the reflective film 26, the first driving member 221 drives the fixed block 2221, the clamping member 2222 and the sandwich plate 2223 to move toward the direction of the pressing mechanism 23 along the driving direction.

[0058] See also Figure 6 and Figure 7 As shown, in one embodiment, the pressing mechanism 23 includes a second driving member 231 and a roller 232. The second driving member 231 is arranged on the substrate 25. The roller 232 is rotatably connected to the output end of the second driving member 231. The second driving member 231 is used to drive the roller 232 to move and press the reflective film 26 down to the photovoltaic backplane pre-configured at the bottom of the reflective film 26.

[0059] In this embodiment, the output end of the second driving member 231 can drive the roller 232 to move along the up and down directions of the substrate 25 so that the reflective film 26 is pressed against the photovoltaic backplane. Since the roller 232 is a cylindrical structure and can roll, the cylindrical surface of the roller 232 contacts the reflective film 26, which helps to reduce the contact area between the reflective film 26 and the roller 232, thereby reducing the adhesion between the reflective film 26 and the roller 232.

[0060] In one embodiment, the second driving member 231 includes a pressing cylinder 2311, a slide plate 2313, a mounting plate 2314 and a buffer block 2312. The pressing cylinder 2311 is installed on the base plate 25. The slide plate 2313 is L-shaped. The slide plate 2313 is slidably connected to one side of the pressing cylinder 2311 and is connected to the output end of the pressing cylinder 2311. The mounting plate 2314 is arranged on the side wall of the slide plate 2313. The roller 232 is installed on the mounting plate 2314. The buffer block 2312 is arranged at the bottom of the slide plate 2313.
