Description

Technical Field

[0001] This utility model relates to the field of concentrated photovoltaic equipment technology, and in particular to a concentrated photovoltaic module assembly device. Background Technology

[0002] Concentrated photovoltaic (CPV) technology is a key technology for improving photovoltaic conversion efficiency and reducing the cost per kilowatt-hour. The assembly precision of CPV modules directly determines the photoelectric performance and long-term reliability of the final product. Compared with traditional flat-panel photovoltaic modules, CPV modules integrate concentrating lens arrays, high-concentration solar cells, heat dissipation carriers, and optical path calibration structures. Therefore, the alignment precision of components during the assembly process is more stringent. Otherwise, the concentrated light spot will shift, significantly reducing the photoelectric conversion efficiency.

[0003] However, the current assembly process of concentrated photovoltaic (CPV) modules still largely relies on assembly tools or general-purpose fixtures designed for traditional photovoltaic modules, which have significant shortcomings in terms of adaptability, accuracy, and efficiency. For example, in some production processes, laser light is used in conjunction with a concentrator with positioning holes to determine and adjust the position of each solar cell chip individually. This process is highly dependent on manual operation, resulting in low assembly efficiency, which cannot meet the needs of large-scale mass production. Furthermore, the assembly accuracy is greatly affected by the operator's experience and skill level, leading to poor product consistency and a high defect rate. Utility Model Content

[0013] Furthermore, the pneumatic clamping block includes a clamping part and a rotating shaft. One end of the rotating shaft is inserted into and rotatably fitted into the pneumatic clamping block fixing block, and the other end of the rotating shaft is fixedly connected to the clamping part.

[0014] Furthermore, the length of the second linear slide rail is less than the length of the first linear slide rail.

[0015] Furthermore, the module placement area of ​​the workbench is provided with several pads, which are used to support the concentrated photovoltaic modules to be assembled.

[0016] Furthermore, the light source is mounted above the workbench via a lamp holder, and the illumination area of ​​the light source covers the module placement area.

[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] The concentrating photovoltaic module assembly device of this invention is used for the installation of a concentrating photovoltaic module 8 with a specific structure, as shown in the reference. Figure 1 Specifically, the assembled concentrating photovoltaic module 8 includes a base plate 81, a lens assembly top plate 82, a frame assembly 83, and several battery strip assemblies 84. The lens assembly top plate 82, the base plate 81, and the frame assembly 83 enclose a closed space. The lens assembly top plate 82 includes several lenses arranged in an array. The battery strip assemblies 84 are located within the closed space. Each battery strip assembly 84 includes a circuit carrier board 841 and several photovoltaic cell chips 842 distributed at equal intervals. The photovoltaic cell chips 842 on each battery strip assembly 84 are connected in series. Positive and negative leads are respectively provided at both ends of the circuit carrier board 841. The frame assembly 83 includes four frames, with upper and lower encapsulation slots respectively provided at the upper and lower ends of the frames. The lens assembly top plate 82 and the base plate 81 are arranged opposite each other. The periphery of the lens assembly top plate 82 is inserted into the upper encapsulation slot of the frame assembly 83, and the periphery of the base plate 81 is inserted into the lower encapsulation slot of the frame assembly 83.

[0037] In this embodiment of the present invention, in the concentrated photovoltaic module 8 to be assembled, two side frames are pre-installed on a set of opposite sides of the base plate 81 and the top plate 82 of the lens group, and the other two opposite side frames are not installed for the time being. Several battery strip assemblies 84 are placed on the base plate 81 at intervals, and the spacing between the battery strip assemblies 84 is adapted to the array spacing of the upper lens of the top plate 82 of the lens group, so that the photovoltaic cell chip 842 of the battery strip assembly 84 and the lens of the top plate 82 of the lens group can be accurately aligned and assembled by the concentrated photovoltaic module assembly device of this embodiment.

[0038] Reference Figures 2-4 This utility model discloses a concentrated photovoltaic module assembly device, including a light source 2, a worktable 1, a module fixing device, a first linear slide rail 4, a sliding device 5, a testing module 6, and a control module 7. The module fixing device includes a first fixing component 31 and a second fixing component 32 disposed opposite to each other on the upper surface of the worktable 1. A set of first linear slide rails 4 are disposed opposite to each other on the upper surface of the worktable 1, and the first fixing component 31, the second fixing component 32, and the set of first linear slide rails 4 surround to form a concentrated photovoltaic module placement area. The light source 2 is disposed above the module placement area. Multiple sliding devices 5 are installed on each set of first linear slide rails 4. The sliding devices 5 can slide along the corresponding first linear slide rail 4.

[0039] The test module 6 is electrically connected to the concentrated photovoltaic module 8 to be assembled, and the control module 7 is electrically connected to the test module 6 and the sliding device 5.

[0040] In this embodiment, the concentrated photovoltaic module placement area can be located in the central area of ​​the upper surface of the workbench 1. The first fixing component 31 can be located on one side of the upper surface of the workbench 1 near the edge, and the second fixing component 32 is located on the opposite side of the first fixing component 31 near the edge. The two are arranged symmetrically or parallel to each other, and together they play a role in fixing the concentrated photovoltaic module 8. A set of first linear slide rails 4 are located on the other two sides of the upper surface of the workbench 1 near the edge, and together with the first fixing component 31 and the second fixing component 32, they enclose the concentrated photovoltaic module placement area. The concentrated photovoltaic module to be assembled is placed in this area, and the first fixing component 31 and the second fixing component 32 fix its two sides.

[0041] The light source 2 is positioned above the concentrated photovoltaic module placement area. During actual installation, it can be fixed in the space above the workbench 1 by the lamp holder 9. The height of the lamp holder can be flexibly adjusted according to the size of the concentrated photovoltaic module 8. The light source 2 is preferably a special light source that can simulate the solar spectrum. Its illumination area can completely cover the module placement area, thereby simulating the actual working light environment of the module during the assembly process and providing real working conditions for the photoelectric performance testing of the test module 6.

[0042] A set of first linear slide rails 4 includes two parallel slide rails. Each slide rail can be equipped with several sliding devices 5 according to the length of the module to be assembled or the number of positioning points required. The sliding devices 5 and the first linear slide rails 4 adopt a slider-slide rail adaptation structure. At the same time, a set of opposing sliding devices 5 is used to clamp a battery bar assembly 84. During assembly, the set of opposing sliding devices 5 clamps both ends of a battery bar assembly 84 and adjusts its position under the signal drive of the control module 7, thereby precisely adjusting the position and angle of the battery bar so that the photovoltaic cell chips 842 on the battery bar assembly 84 correspond one-to-one with the lenses of the lens group top plate 82.

[0043] Test module 6 is used to test the photoelectric performance of the concentrated photovoltaic module to be assembled. Its electrical connection to the module can be achieved via wires. For example, test module 6 is electrically connected to the module via multiple adjustable test probes. In use, the probes are aligned with the positive and negative leads at both ends of the module's circuit board 841 to collect parameters such as the operating current of the chip series group on each battery strip assembly in real time. During specific testing, the position of the sliding device is adjusted by control module 7. When the operating current measured by test module 6 reaches the preset maximum operating current, the current position of the battery strip assembly is determined as the alignment position and fixed. This achieves precise and rapid alignment and assembly of the photovoltaic cell chip 842 of the battery strip assembly 84 with the lens of the lens group top plate 82.

[0044] The control module 7 includes a data interaction screen and a data processor, which can be installed on one side of the workbench 1. The control module 7 is electrically connected to the test module 6 and the sliding device 5 via wires. It is used to receive performance test data transmitted by the test module 6 and send control signals to the sliding device 5 according to the preset program or test data, driving the sliding device 5 to slide along the first linear slide rail 4 to the target position. This achieves precise positioning and adjustment of the module during the assembly process. At the same time, it can also judge whether the module assembly meets the standards based on the test data. If there is a deviation, the position of the sliding device 5 is adjusted in time to improve the assembly accuracy and efficiency. Since the photovoltaic cell chips 842 on the battery bar assembly 84 are evenly distributed and adapted to the lens array of the lens group top plate 82, in actual adjustment, only the photovoltaic cell chips 842 at the end of the battery bar assembly 84 need to be aligned and calibrated with the lens to quickly complete the precise alignment of the entire battery bar, which greatly improves the assembly accuracy and efficiency.

[0045] The concentrated photovoltaic module assembly device of this embodiment uses a light source to simulate real lighting conditions. It uses a module fixing device to limit the position of the concentrated photovoltaic module to be assembled, and then uses a first linear slide rail and a sliding device to achieve precise adjustment of the position of the battery bar. At the same time, the test module provides real-time feedback on photoelectric performance, and the control module automatically adjusts the sliding device according to the feedback. This solves the problems of low accuracy and poor efficiency of manual alignment in traditional concentrated photovoltaic module assembly, ensures the alignment accuracy of the lens and photovoltaic cell chip, significantly improves assembly efficiency, and reduces reliance on manual labor and the defect rate.

[0046] In some specific embodiments, reference is made to Figure 3 and Figure 4 The first fixing component 31 is an elongated limiting component. The bottom edge of the elongated limiting component is fixed to the upper surface of the workbench 1, and the side edge of the elongated limiting component is perpendicular to the upper surface of the workbench 1 and extends towards the module placement area to limit the concentrating photovoltaic module 8 to be assembled in the module placement area on one side. In practical applications, the elongated limiting component is preferably an L-shaped angle steel, whose bottom edge is fixed to the upper surface of the workbench 1 by bolts, welding or other fasteners, and the length direction of the bottom edge is consistent with the extension direction of the corresponding side edge on the workbench 1; the side edge of the elongated limiting component is perpendicular to the upper surface of the workbench 1 and extends towards the concentrating photovoltaic module placement area. When the concentrating photovoltaic module 8 to be assembled is placed in the module placement area, one edge of the concentrating photovoltaic module 8 will abut against the side edge of the elongated limiting component, thereby using this side edge to limit the concentrating photovoltaic module 8 in one direction and prevent displacement.

[0047] In some specific embodiments, refer to Figure Figure 3 and Figure 9The second fixing component 32 includes a plurality of clamps 321 and a plurality of pads 322 corresponding to each clamp 321. The pads 322 are fixed to the upper surface of the workbench 1. The clamps 321 are mounted on the corresponding pads 322, with the clamping ends of the clamps 321 facing the module placement area, to limit or clamp the side of the concentrated photovoltaic module 8 to be assembled away from the first fixing component 31. In this embodiment, the pads 322 are fixed to the upper surface of the workbench 1 by bolt connection or welding, etc. The clamps 321 can be selected from, for example, Figure 9 The push-pull quick-release clamps are shown, with the clamping ends of the clamps 321 facing the module placement area. When the concentrated photovoltaic module 8 to be assembled is placed in the module placement area, and one side abuts against the side of the elongated limiting member of the first fixing component 31, the clamps 321 are operated to move the clamping ends toward the module. This limits the side of the concentrated photovoltaic module 8 to be assembled away from the first fixing component 31, preventing the module from shifting during assembly. The number of clamps 321 and pads 322 can be flexibly adjusted according to the length of the concentrated photovoltaic module 8. For example, for a longer module, 2 to 4 sets of clamps 321 and pads 322 can be spaced along the side of the module to achieve uniform clamping of different parts of the module, further improving the fixing stability.

[0048] In some specific embodiments, reference is made to Figure 4 The number of sliding devices 5 installed on the first set of linear slide rails 4 is the same. Specifically, if the concentrated photovoltaic module 8 to be assembled needs to hold 4 battery strip assemblies 84, then 4 sliding devices 5 need to be installed on the first linear slide rails 4 on both sides respectively, and the sliding devices 5 on both sides need to be arranged one-to-one along the length of the slide rail. That is, the first sliding device on the left slide rail and the first sliding device on the right slide rail are on the same straight line perpendicular to the extension direction of the slide rail, and the second one on the left and the second one on the right are also on the same line, and so on. The number of sliding devices 5 can be flexibly adjusted according to the number of battery strip assemblies 84 to be assembled.

[0049] In some specific embodiments, reference is made to Figure 5 and Figure 6The sliding device 5 includes a first slider 51, a U-shaped component 52, a second linear slide rail 53, a second slider 54, a pneumatic clamping block fixing block 55, and a pneumatic clamping block 56. The first slider 51 is slidably mounted on the first linear slide rail 4, the U-shaped component 52 is fixed on the first slider 51, the second linear slide rail 53 is fixed inside the U-shaped component 52, and the extension direction of the second linear slide rail 53 is perpendicular to the extension direction of the first linear slide rail 4. The second slider 54 is slidably mounted on the second linear slide rail 53, the pneumatic clamping block fixing block 55 is fixedly connected to the second slider 54, and the pneumatic clamping block 56 is mounted on the pneumatic clamping block fixing block 55. The bottom of the U-shaped component 52 is fixed to the upper surface of the first slider 51 by bolts or welding; the second linear slide rail 53 is fixed in the inner groove of the U-shaped component 52 by fasteners. The first linear slide rail 4 extends along the Y-axis direction, and the second linear slide rail 53 extends along the X-axis direction. The second slider 54 has a slot on its side that matches the second linear slide rail 53. Through the sliding engagement of the slot with the second linear slide rail 53, it can move flexibly along the extension direction of the second linear slide rail 53. The lower surface of the pneumatic clamping block 55 is fixedly connected to the upper surface of the second slider 54 by bolts or other means. Figure 7 As shown, the pneumatic clamping block fixing block 55 has a mounting hole 551 that matches the pneumatic clamping block 56, which is used to achieve a stable assembly of the pneumatic clamping block 56. The pneumatic clamping block 56 is used to clamp the battery pack assembly 84. The pneumatic clamping block 56 is fixed to the pneumatic clamping block fixing block 55 through the mounting hole, and its clamping direction is towards the center of the module placement area. When it is necessary to fix the battery pack assembly 84, the grippers of the pneumatic clamping block 56 can close under air pressure to clamp the end of the battery pack assembly 84. After adjustment, it can be released or kept in the clamping state as needed.

[0050] In some specific embodiments, reference is made to Figure 10 The sliding device 5 further includes a first driving mechanism, a second driving mechanism, and a third driving mechanism; the first driving mechanism is drivenly connected to the first slider 51 and is used to drive the first slider 51 to move along the first linear slide rail; the second driving mechanism is drivenly connected to the second slider 54 and is used to drive the second slider 54 to move along the second linear slide rail; the third driving mechanism is drivenly connected to the pneumatic clamp 56 and is used to drive the pneumatic clamp 56 to rotate around its own central axis; the first driving mechanism, the second driving mechanism, and the third driving mechanism are all electrically connected to the control module 7.

[0051] The first, second, and third drive mechanisms can all employ existing structures using micro motors and lead screw drives. These drive mechanisms, as common and mature technologies for achieving precise linear or rotary motion in automated equipment, have specific structural details well-known to those skilled in the art, and can be conventionally selected and configured according to actual load, speed, and accuracy requirements. Therefore, to make the accompanying drawings more concise and clear, and to highlight the core innovations of this utility model, the internal structures of these drive mechanisms, which fall within the scope of existing technology, are not separately illustrated in the drawings. However, those skilled in the art can fully understand and implement the aforementioned drive connection relationships. The control module 7 can precisely control the start / stop, speed, and direction of rotation of these drive mechanisms by sending electrical signals, thereby achieving multi-dimensional, high-precision automated adjustment of the sliding device 5's translation in the X and Y axes and its rotation around the Z axis.

[0052] Specifically, the micro motor of the first drive mechanism is fixed to the end of the first linear slide rail 4, and the motor output shaft is connected to a lead screw, which is adapted to and connected to the first slider 51. When the control module 7 sends an electrical signal to the first drive mechanism, the micro motor rotates, causing the lead screw to rotate, which in turn drives the first slider 51 to slide smoothly along the first linear slide rail 4, thereby realizing the position adjustment of the battery pack assembly 84 in the Y-axis direction. The transmission method of the second drive mechanism is similar to that of the first drive mechanism, driving the second slider 54 to slide along the second linear slide rail 53, thereby realizing the position adjustment of the battery pack assembly 84 in the X-axis direction.

[0053] The third drive mechanism 59 is connected to the pneumatic clamp 56 and is used to drive the pneumatic clamp 56 to rotate around its own central axis. The third drive mechanism 59 is preferably a micro servo motor, which is installed inside or on the side of the pneumatic clamp fixing block 55. The motor output shaft is connected to the rotation shaft of the pneumatic clamp 56. When the control module 7 sends an electrical signal, the micro servo motor runs, driving the pneumatic clamp 56 to rotate around its own central axis, thereby finely adjusting the angle of the battery strip assembly 84 to ensure that the photovoltaic cell chip 842 is accurately aligned with the lens of the lens group top plate 82.

[0054] The control module 7 can send control signals to the three components based on the preset program or the photoelectric performance data fed back by the test module 6, and coordinate the Y-axis movement of the first slider 51, the X-axis movement of the second slider 54, and the rotation of the pneumatic clamp 56 to achieve multi-dimensional automated adjustment of the battery strip assembly 84, which greatly improves the accuracy and efficiency of the alignment between the photovoltaic cell chip and the lens and reduces the error caused by manual intervention.

[0055] In some specific embodiments, reference is made to Figure 8The pneumatic clamp 56 includes a clamping part 561 and a rotating shaft 562. One end of the rotating shaft 562 is inserted into and rotatably fitted into the pneumatic clamp fixing block 55, and the other end of the rotating shaft 562 is fixedly connected to the clamping part 561. When the third drive mechanism 59 drives the rotating shaft 562 to rotate, the clamping part 561 will rotate around the central axis of the rotating shaft 562, thereby causing the clamped battery bar assembly 84 to be finely adjusted in angle.

[0056] In some specific embodiments, reference is made to Figure 5 and Figure 6 The length of the second linear slide rail 53 is less than the length of the first linear slide rail 4. The first linear slide rail 4 is used to drive the sliding device 5 and the clamped battery strip assembly 84 to move a wide range along the length direction (Y-axis) of the concentrating photovoltaic module 8. Its length needs to cover the entire length of the module placement area to ensure that the battery strip assembly 84 can be picked up, placed, and positioned in all positions within the module, thus requiring a longer stroke. The second linear slide rail 53 is used for fine position adjustment of the battery strip assembly 84 perpendicular to the length direction (X-axis) of the module. Its adjustment range usually only needs to cover the width of a single lens on the top plate 82 of the lens group or the spacing between adjacent lenses, used to precisely align the photovoltaic cell chip 842 on the battery strip assembly 84 to the center of the corresponding lens spot. Therefore, its required adjustment stroke is relatively short.

[0057] In some specific embodiments, reference is made to Figure 4 The workbench 1 has a plurality of pads 10 on its module placement area surface, which support the concentrated photovoltaic module 8 to be assembled. Exemplarily, the pads 10 are evenly spaced to provide multi-point uniform support for the concentrated photovoltaic module 8. The upper surfaces of all pads 10 should be on the same horizontal plane to ensure that the concentrated photovoltaic module 8 remains horizontal throughout the assembly process. The height of the upper surfaces of the pads 10 should be lower than the clamping portion 561 of the pneumatic clamping block 56 to prevent the clamping portion 561 from interfering with the pads 10 or the base plate 81 of the concentrated photovoltaic module when it is near the battery strip.

[0058] In some specific embodiments, reference is made to Figure 1 The light source 2 is mounted above the workbench 1 via a lamp holder 9, and the illumination area of ​​the light source 2 covers the module placement area. The height of the light source 2 is adjustable, allowing operators to flexibly adjust the height of the light source 2 according to the size and height of the concentrated photovoltaic module 8 to be assembled, in order to obtain optimal light intensity and uniformity.

[0059] Reference Figures 1-10 The concentrating photovoltaic module assembly device of this utility model includes the following in the specific assembly and use process:

[0060] First, the semi-finished concentrated photovoltaic module (with two pre-installed side frames) is placed on several pads in the module placement area of ​​the workbench. A first fixing component provides limiting support on one side of the module, while a second fixing component's clamps are fixed to the other side of the workbench via pads, holding the side of the module away from the first fixing component. Then, the height of the lamp holder is adjusted so that the light source illumination area completely covers the module placement area, simulating sunlight operation.

[0061] Next, several battery bar assemblies are placed at intervals on the base plate of the concentrating photovoltaic module (at this time, there may be initial alignment deviation between the battery bars and the lenses on the top plate of the lens group). After the device is started, the control module drives the sliding device to move along the first linear slide rail, so that the pneumatic clamps reach the two ends of each battery bar, and clamp the battery bars through the clamping parts of the pneumatic clamps; at the same time, the multi-channel probes of the test module are connected to the positive and negative leads at the beginning and end of the battery bars to establish electrical connections for collecting photoelectric performance data.

[0062] Afterwards, the control module turns on the light source, and the testing module collects the operating current of the photovoltaic cell chip series array on each battery bar in real time. Based on the collected current data, the control module sends control signals to the first, second, and third drive mechanisms of the sliding device: the first drive mechanism moves the battery bar along the first linear slide rail, the second drive mechanism moves the battery bar along the second linear slide rail, and the third drive mechanism drives the pneumatic clamp to rotate to fine-tune the angle of the battery bar. During the adjustment process, the testing module continuously feeds back current data. When the operating current of a battery bar reaches the preset maximum operating current, the control module stops the adjustment of the sliding device corresponding to that battery bar. At this time, the photovoltaic cell chip on the battery bar is precisely aligned with the lens on the top plate of the lens group.
