Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic module lamination, and in particular to a photovoltaic laminator. Background Technology

[0002] The lamination process in photovoltaic module manufacturing involves heating and pressurizing a laminate containing a cover glass, solar cell strings, encapsulating film, and backsheet in a laminator to melt the encapsulating film and bond the cells, cover glass, and backsheet together to form a laminate. To prevent uneven stress on the edges of the laminate during lamination, a lamination frame (hereinafter referred to as a framed laminate) is usually placed around the laminate before it enters the laminator.

[0003] In actual production, situations can occur where the laminating frame misaligns and presses onto the laminated components. If this isn't detected in time, it can lead to glass breakage during lamination. Currently, the main method for determining whether a framed laminate is pressing onto the laminated component before it enters the laminator's feed inlet is manual inspection. However, manual inspection is prone to misjudgment. Utility Model Content

[0004] Based on this, this utility model embodiment provides a photovoltaic laminator, which sets a thickness detection mechanism in front of the feed inlet of the lamination mechanism. By detecting the thickness of the framed stacked components, it can determine whether there is a situation where the lamination frame is pressing on the stacked components, thus solving the problem of misjudgment that is easy to occur by manual visual observation.

[0005] Specifically, this includes the following technical solutions.

[0006] This utility model provides a photovoltaic laminator, including a lamination mechanism and a conveying platform disposed in front of the feed inlet of the lamination mechanism, and further including a thickness detection mechanism fixed on the conveying platform.

[0007] The thickness measurement mechanism includes measurement components, which include:

[0008] Mounting components fixed to the conveyor platform, and,

[0009] The abutment component is connected to the mounting component. The lower end of the abutment component can move vertically. The vertical movement distance of the abutment component is used to provide feedback on the thickness of the framed laminate.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] In one implementation, the detection component also includes: a position detection element and a position sensing element;

[0012] One of the position detection element and the position sensing element is fixed on the abutting part and moves synchronously with the abutting part in the vertical direction, while the other is connected to the mounting part;

[0013] There is an initial preset distance between the position detection element and the position sensing element. When the contacting part moves upward and triggers the position detection element and the position sensing element, the position sensing element outputs a trigger signal.

[0014] In one implementation, the abutment component includes:

[0015] The roller has a circular arc surface, its axis is set in the horizontal direction, and it can rotate in the axial direction.

[0016] In this implementation, the lower end of the arc surface of the roller is used to abut against the top surface of the photovoltaic frame module.

[0017] In one implementation, the abutment component also includes:

[0018] A rotating shaft, which is arranged laterally and connected to the mounting component;

[0019] A first connector, one end of which is rotatably connected to the mounting component via a rotating shaft, and the other end of which is connected to the roller; a position detection element or position sensing element is connected to the first connector.

[0020] In one implementation, the position detection element is connected to the first connector, and the position sensing element is connected to the mounting element. The position sensing element is elongated and its length extends vertically.

[0021] In one implementation, the position detection element and the position sensing element form a slotted photoelectric sensing structure;

[0022] The abutment components also include:

[0023] The second connector is L-shaped. One end of the L-shaped second connector is connected to the mounting piece, and the other end of the L-shaped second connector extends toward the position detection element and is connected to the position sensing element.

[0024] In one implementation, the abutment component also includes:

[0025] The third connector connects the first connector to the roller. The third connector is in the shape of an inverted U. The top of the inverted U of the third connector is connected to the end of the first connector away from the axis of rotation. The two side walls of the inverted U of the third connector are connected to the two ends of the roller, respectively.

[0026] In one implementation, the thickness detection mechanism further includes: a frame assembly fixed to the conveying platform; an installation component connected to the frame assembly, and multiple detection components connected to the frame assembly laterally.

[0027] In this implementation, multiple detection components are used to simultaneously detect the thickness of the photovoltaic frame module at multiple locations along its length or width.

[0028] In one implementation, the transmission platform includes a machine;

[0029] The framework components include:

[0030] Vertical mounting rods are fixed to the top surface of the worktable and at least two of them are provided.

[0031] A horizontal mounting rod is provided, with its two ends connected to two vertical mounting rods respectively. At least two detection components are connected to the horizontal mounting rod along its length.

[0032] In one implementation, both the vertical mounting rod and the horizontal mounting rod are strip-shaped profile structures.

[0033] In one implementation, the lateral mounting bar includes:

[0034] The chute is set along the length of the transverse mounting rod and is connected to the detection assembly by a bolt and nut structure.

[0035] The framework components also include:

[0036] Angle bracket, which is triangular in shape and connected to both the vertical mounting rod and the horizontal mounting rod.

[0037] The beneficial effects of this utility model are as follows: In the photovoltaic laminator provided in this utility model embodiment, a thickness detection mechanism is set in front of the feed inlet of the laminating mechanism. When the framed laminate is transferred from the upstream lamination process to the feed inlet of the laminating mechanism, if the lamination frame presses on the laminate when it passes through the thickness detection mechanism, the thickness of the overlapping part of the lamination frame and the laminate will exceed the thickness of the framed laminate under normal circumstances. In the thickness detection mechanism, the lower end of the abutting member is used to abut against the framed laminate, and the abutting member can move vertically according to the thickness change of the framed laminate. That is, when the framed laminate passes through the thickness detection mechanism, the lower end of the abutting member contacts the surface of the framed laminate. When the thickness of the framed laminate increases, the abutting member will be pushed upward. It can be seen that the vertical height change of the abutting member can reflect the thickness of the framed laminate.

[0038] By using a thickness detection mechanism to detect changes in the thickness of the framed laminate, it is more accurate than manual visual inspection to determine whether the laminating frame is pressing on the laminate. This allows for timely handling of framed laminates where the laminating frame is pressing on the laminate, effectively reducing problems such as component bursting inside the laminator and providing better protection for the laminator.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application. It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show components related to this utility model and are not drawn according to the actual number, shape, and size of the components. In actual implementation, the shape, quantity, and proportion of each component can be arbitrarily changed, and the component layout may also be more complex.

[0052] In the photovoltaic module manufacturing process, the lamination process is completed using a laminator. A laminator typically consists of a lamination mechanism with an inlet and an outlet. A conveyor platform is located in front of the inlet, through which the laminated assembly, containing cover glass, solar cell strings, encapsulating film, and backsheet, transported from upstream processes, enters the lamination mechanism. Inside the lamination mechanism, air is extracted from the laminated assembly through vacuuming, and the encapsulating film is melted by heating and pressurizing, bonding the cells, cover glass, and backsheet together to form the laminated assembly. The laminated assembly is output from the outlet of the lamination mechanism. To prevent uneven stress on the edges of the laminated assembly during lamination, a lamination frame (i.e., a framed laminated assembly) is usually fitted around the laminated assembly before it enters the laminator. In the actual production of photovoltaic modules, the laminating frame may be placed improperly, deformed, or misaligned during transportation, which may cause the laminating frame to press on the laminated component. If this is not detected in time, such a framed laminated component may enter the lamination mechanism, which may easily lead to the problem of the module exploding during the lamination process (i.e., the glass in the photovoltaic module is crushed).

[0053] Under normal circumstances, the thickness of the framed laminate is uniform. However, if the laminating frame presses onto the laminate, the thickness of the overlapping portion will exceed the normal thickness of the framed laminate. Based on this principle, in this embodiment of the invention, a thickness detection mechanism is installed in front of the lamination mechanism's feed inlet to detect the thickness of the framed laminate before it enters the lamination mechanism. The thickness detection result is used to determine whether the problem of the laminating frame pressing onto the laminate has occurred.

[0054] Figure 3 The structure of the laminator in an embodiment of this utility model is shown. For example... Figure 3 As shown, the photovoltaic laminator provided in this embodiment of the present invention includes a lamination mechanism 3, a conveying platform 4 disposed in front of the feed inlet of the lamination mechanism 3, and a thickness detection mechanism 2 fixed on the conveying platform 4.

[0055] "In front of the feed inlet" refers to the direction upstream of the feed inlet on the photovoltaic module production line, along the material conveying direction of the production line. That is, after the framed laminate 1 is transferred from the upstream process to the laminator, it first passes through the thickness detection mechanism 2 and then enters the lamination mechanism 3 through the feed inlet.

[0056] Figure 2 The structure of the thickness detection mechanism is shown, such as Figure 2 As shown, the thickness detection mechanism 2 includes a detection component 21.

[0057] Figure 1 The structure of the detection component 21 is shown, as follows: Figure 1As shown, the detection component 21 includes: a mounting component 211 fixed on the conveying platform 4; and an abutting component connected to the mounting component 211. The lower end of the abutting component can move in the vertical direction, and the vertical movement distance of the abutting component is used to provide feedback on the thickness of the frame-stacked component 1.

[0058] The conveying platform 4 may include a machine base 221 and a conveyor belt mounted on the machine base 221. The conveyor belt is used to transport the frame-stacked laminate. The mounting component 211 can be fixed to the machine base 221 of the conveying platform 4, maintaining a fixed position. The lower end of the abutment component is used to abut against the top surface of the frame-stacked laminate 1. When the frame-stacked laminate passes the thickness detection mechanism, the lower end of the abutment component contacts the surface of the frame-stacked laminate. When the thickness of the frame-stacked laminate increases, the abutment component is pushed upward; when the thickness of the frame-stacked laminate decreases, the abutment component moves downward. It can be seen that the change in the vertical height of the abutment component can reflect the thickness of the frame-stacked laminate. Therefore, the thickness detection mechanism can detect the change in the thickness of the frame-stacked laminate to determine whether the laminating frame is pressing on the laminate, which is more accurate than manual visual observation. This facilitates timely handling of frame-stacked laminates with laminating frames pressing on the laminate, effectively reducing problems such as component bursting inside the laminator.

[0059] In the photovoltaic laminator provided in this embodiment of the utility model, such as Figure 1 As shown, the detection component 21 also includes a position detection element 213 and a position sensing element 214.

[0060] In this design, one of the position detection element 213 and the position sensing element 214 is fixed to the abutting component and moves synchronously with the abutting component in the vertical direction, while the other is connected to the mounting component 211. There is an initial preset distance between the position detection element 213 and the position sensing element 214. When the abutting component moves upward and triggers both the position detection element 213 and the position sensing element 214, the position sensing element 214 outputs a trigger signal.

[0061] In this embodiment of the invention, a position detection element 213 and a position sensing element 214 are further configured to detect changes in the height of the abutting component, thereby detecting changes in the thickness of the framed laminate 1. An initial preset distance may exist between the position detection element 213 and the position sensing element 214, which may be slightly greater than the thickness of the framed laminate under normal conditions. When the lower end of the abutting component contacts the upper surface of the framed laminate 1, the distance between the position detection element 213 and the position sensing element 214 decreases as the abutting component moves upward. If the laminated frame does not press against the laminate, the relative movement distance between the position detection element 213 and the position sensing element 214 will not exceed the initial preset distance, and they will not contact each other. If the laminated frame presses against the laminate, the position detection element 213 and the position sensing element 214 will be triggered as the upward movement distance of the abutting component exceeds the initial preset distance, causing the position sensing element 214 to output a trigger signal.

[0062] The aforementioned trigger signal can be a light signal or a sound signal; alternatively, an alarm light or sound alarm can be set up that is electrically connected to the position sensing element 214. When the position sensing element 214 is triggered, it sends a trigger signal, which is then transmitted to the alarm light or sound alarm to issue an alarm signal. This alerts on-site personnel that a laminate frame has been pressing on the laminated component, allowing them to stop the machine, prevent the laminate frame from pressing on the laminated component, or remove the problematic laminated component with the frame.

[0063] In the embodiment, "moving synchronously with the abutting component in the vertical direction" means that both components move upward or downward simultaneously in the vertical direction. That is, when the abutting component moves in the vertical direction, the position detection element 213 or position sensing element 214 connected to the abutting component will move in the vertical direction synchronously. This allows timely feedback on whether the thickness of the framed laminate 1 exceeds a threshold by whether the two elements generate trigger feedback. However, it should be noted that synchronous movement here does not mean that the abutting component and the element move the same distance in the vertical direction. It only means that they move at the same time and in the same direction.

[0064] In one embodiment regarding thickness, before lamination, the lamination frame is 6mm-7mm thick, and the laminate is 7mm-9mm thick; after lamination, the laminate is approximately 5mm thick. The initial preset distance can be set to 12mm. When the framed laminate 1 passes the thickness detection mechanism 2, if the overall thickness exceeds 12mm, the position sensing element 214 will be triggered to send a signal.

[0065] In some embodiments of this application, the abutting component includes a roller 2121. The roller 2121 is axially arranged in a horizontal direction and is rotatable in the axial direction. The lower end of the arc surface of the roller 2121 is used to abut against the top surface of the framed laminate 1. In this way, by using the axially rotatable roller 2121 to abut against the framed laminate 1, when the framed laminate 1 is pushed under the roller 2121, the rotating roller 2121 abuts against the framed laminate 1 and forms a rolling abutting structure, which reduces the frictional force between the framed laminate 1 and the abutting component and effectively reduces frictional damage to the framed laminate 1.

[0066] In some embodiments of this application, see Figure 1 The abutting component also includes a rotating shaft 2122 and a first connecting member 2123. The rotating shaft 2122 is arranged laterally and connected to the mounting member 211. One end of the first connecting member 2123 is rotatably connected to the mounting member 211 via the rotating shaft 2122, and the other end of the first connecting member 2123 is connected to the roller 2121. A position detection element 213 or a position sensing element 214 is connected to the first connecting member 2123. Thus, when the roller 2121 at the bottom of the abutting component abuts against the framed laminate 1, since the roller 2121 is connected to one end of the first connecting component 2123, that end of the first connecting component 2123 can be driven to move vertically. Since the other end of the first connecting component 2123 is connected to the mounting component 211 through the rotating shaft 2122, the other end of the first connecting component 2123 will rotate around the rotating shaft 2122 when the roller 2121 moves vertically. By connecting the position detection element 213 or the position sensing element 214 to the first connecting component 2123, the position detection element 213 or the position sensing element 214 is prevented from being affected by the rotation of the roller 2121, while achieving the effect of the position detection element 213 or the position sensing element 214 moving vertically synchronously with the abutting component.

[0067] In other embodiments, see Figure 1 The rotating shaft 2122 is connected to the lower end of the mounting component 211, thereby facilitating the first connecting component 2123 to rotate around the mounting component 211 via the rotating shaft 2122.

[0068] In some embodiments of this application, the position detection element 213 is connected to the first connector 2123, and the position sensing element 214 is connected to the mounting member 211. The position sensing element 214 is elongated and its length extends vertically. Thus, by connecting the position sensing element 214 to the mounting member 211 to determine its vertical position, and by connecting the position detection element 213 to the first connector 2123 such that the position of the position detection element 213 moves vertically with the thickness of the framed laminate 1, when the thickness of the framed laminate 1 exceeds a maximum limit, the position detection element 213 will move upwards to trigger the position sensing element 214. By setting the position sensing element 214 to be elongated, even framed laminates 1 with significantly greater thicknesses can be detected, thereby increasing the detection range of the position detection element 213 for framed laminates 1 with thicknesses exceeding the standard.

[0069] In other embodiments, the position sensing element 214 is elongated, with the lower end of the position sensing element 214 serving as the minimum limit for excessive thickness, and the upper end of the position sensing element 214 extending upward in the vertical direction.

[0070] In some embodiments of this application, see Figure 1 The position detection element 213 and the position sensing element 214 form a slotted photoelectric sensing structure. In this way, the thickness of the framed laminate 1 is detected using the slotted photoelectric sensing structure, achieving the required detection accuracy while facilitating structural installation.

[0071] The abutting component also includes a second connector 2124, which is L-shaped. One end of the L-shaped second connector 2124 is connected to the mounting member 211, and the other end of the L-shaped second connector 2124 extends toward the position detection element 213 and is connected to the position sensing element 214. In this way, the position sensing element 214 and the mounting member 211 are connected by the second connector 2124, thereby facilitating the adjustment of the position of the position sensing element 214.

[0072] In this embodiment, a slot-type photoelectric sensor is used. This sensor consists of a light source and a receiver. It detects position by blocking light when an object enters the slot, and is commonly used in position detection in small automated equipment. Alternatively, a through-beam photoelectric sensor can be used. Its light source, such as a light-emitting diode (LED), emits light, typically infrared or visible light. When the light path is blocked by an object, the receiver on the other side does not receive the light signal, thus detecting the object's position. This can be used to detect whether the position height meets the standard. However, if a through-beam photoelectric sensor is used, the corresponding connection structure needs to be adapted accordingly.

[0073] In some embodiments of this application, see Figure 1The abutting component also includes a third connecting member 2125. The first connecting member 2123 is connected to the roller 2121 through the third connecting member 2125. The third connecting member 2125 is inverted U-shaped, with the top of the inverted U-shape connected to the end of the first connecting member 2123 away from the rotation axis 2122. The two side walls of the inverted U-shape of the third connecting member 2125 are respectively connected to the two ends of the roller 2121. In this way, the roller 2121 is easily connected to the first connecting member 2123 through the third connecting member 2125, and the U-shaped third connecting member 2125 can stably connect the roller 2121 to the first connecting member 2123.

[0074] In other embodiments, see Figure 1 The roller 2121 is rotatable, and a second rotating shaft 2122 extends axially from the roller 2121. The second rotating shaft 2122 is connected to the two inverted U-shaped side walls of the third connecting member 2125. The roller 2121 and the second rotating shaft 2122 can be two independent and rotatably connected workpieces. The second rotating shaft 2122 can also be a structure integrally formed with the roller 2121. A clamping sleeve is provided at the position where the second rotating shaft 2122 extends out of the two inverted U-shaped side walls of the third connecting member 2125. The clamping sleeve is used to prevent the second rotating shaft 2122 from coming off the third connecting member 2125.

[0075] In some embodiments of this application, see Figure 1 and Figure 2 The thickness detection mechanism 2 also includes a frame assembly 22. A mounting component 211 is connected to the frame assembly 22. Multiple detection components 21 are connected laterally to the frame assembly 22. These multiple detection components 21 are used to simultaneously detect the thickness of the framed laminate 1 at multiple locations along its length or width. By simultaneously connecting multiple detection components 21 to the frame assembly 22, multiple locations of the framed laminate 1 can be measured synchronously, increasing the number of locations where the thickness of the framed laminate 1 can be measured at once. This reduces the probability of deformed components being detected by the thickness detection mechanism 2, thereby improving the quality of the framed laminate 1 passing through the thickness detection mechanism 2. The frame assembly 22 can be mounted on the machine base 221.

[0076] Specifically, when measuring the framed laminate 1, the length or width direction of the framed laminate 1 can be set to be parallel to the length direction of the frame assembly 22, so as to increase the number of continuous measurement positions during the movement of the entire framed laminate 1 and speed up the efficiency of the framed laminate 1 passing through the detection assembly 21.

[0077] In some embodiments of this application, see Figure 2The frame assembly 22 includes vertical mounting rods 222 and horizontal mounting rods 223. At least two vertical mounting rods 222 are fixed to the top surface of the machine base 221. When there are two vertical mounting rods 222, they can be fixed to opposite sides of the machine base 221. The two ends of the horizontal mounting rods 223 are connected to the two vertical mounting rods 222, and at least two detection components 21 are connected to the horizontal mounting rods 223 along their length. Thus, the framed laminated component 1 is placed in the space between the horizontal mounting rods 223 and the machine base 221, allowing the detection components 21 to be positioned along the length of the horizontal mounting rods 223 and to measure the thickness of the framed laminated component 1 located below.

[0078] In other embodiments, see Figure 2 The framed laminate 1 is laid on the machine base 221. The frame assembly 22 is arranged along the length of the framed laminate 1. Multiple detection components 21 are evenly distributed along the same straight line, and the arrangement direction of the multiple detection components 21 is parallel to the length direction of the framed laminate 1. When there are five detection components 21, the two detection components 21 located at both ends abut against the two edges of the lamination frame, and the remaining detection components 21 are used to detect the thickness in the middle of the framed laminate 1.

[0079] In some embodiments of this application, see Figure 2 Both the vertical mounting rod 222 and the horizontal mounting rod 223 are strip-shaped profile structures. This results in high stability of the profile structure, and the structure is easy to adjust after the profiles are connected. Furthermore, using a profile structure also helps reduce costs.

[0080] The transverse mounting rod 223 includes a sliding groove, which is set along the length of the transverse mounting rod 223 and is connected to the detection component 21 by a bolt and nut structure. In this way, the position of the detection component 21 can be adjusted by means of the sliding groove, which facilitates the measurement of framed laminated parts 1 of different sizes by this device, and also facilitates the adjustment of the transverse position distribution or number of the detection components 21.

[0081] Frame component 22 also includes corner code 224, see Figure 2 The corner bracket 224 is triangular in shape and is connected to both the vertical mounting rod 222 and the horizontal mounting rod 223. This corner bracket 224 connects the vertical mounting rod 222 and the horizontal mounting rod 223, facilitating adjustment of their connection positions to adjust the thickness of the framed laminate 1 corresponding to the triggering of the adjustable position detection element 213 and the position sensing element 214.

[0082] like Figure 3 As shown, a double-layer laminator has two conveyor platforms 4 (upper and lower layers) and a lamination mechanism 3. Thickness detection mechanisms 2 can be installed on both the upper and lower conveyor platforms 4.

[0083] In summary, this utility model embodiment can continuously detect the thickness of the framed laminate before it enters the lamination mechanism. By detecting the thickness, it can identify situations where the lamination frame is pressing on the laminate, which can more accurately and promptly detect abnormal framed laminates. This facilitates timely handling of framed laminates with the lamination frame pressing on the laminate, effectively reducing problems such as component explosions in the laminator.
