Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module manufacturing technology, and in particular relates to a junction box calibration mechanism and calibration device. Background Technology

[0002] The junction box for a photovoltaic module includes a box body and leads connected to the box body. The leads are wound to form a coil with a ring structure. The box body is positioned on the glass surface of the photovoltaic module. To prevent the coil from sagging or falling and affecting the transmission of the photovoltaic module, the coil is fixed in place. The fixing method is to snap one side of the coil into the inside of the frame. This positioning of the coil ensures that even when the junction box is facing down, the coil will not sag or fall, thus avoiding any impact on the transmission of the photovoltaic module.

[0003] However, some problems may arise during the actual production of photovoltaic modules. For example, the casing cover may not be securely installed; the coils may also be misaligned, failing to engage properly within the frame. Specifically, part of the coil may be on the surface of the module glass, while another part may be resting on the top of the frame. Figure 4 As shown, when the photovoltaic module is positioned with the junction box facing downwards, the coil will droop downwards, affecting the photovoltaic module's power supply. Therefore, a corresponding correction mechanism needs to be designed to both press the box cover firmly and correct the coil's position, allowing the coil to re-engage into the inner side of the frame, thus achieving coil positioning and correcting the junction box's position.

[0004] Therefore, it is necessary to provide a junction box calibration mechanism and calibration device to solve the above-mentioned technical problems. Utility Model Content

[0034] Please refer to Figures 1-6 This embodiment is a junction box calibration device 100, which includes a frame 5, a conveyor line 1, a blocking component 2 disposed at the front end of the conveyor line 1, a correction component 3 disposed on both sides of the conveyor line 1, and a junction box calibration mechanism 4 disposed above the conveyor line 1.

[0035] In this embodiment, conveyor line 1 is used to transport photovoltaic modules 300. It is a belt conveyor with four belts arranged in parallel to ensure stable transport. Other conveying methods may be used in other embodiments, and are not limited here.

[0036] The blocking component 2 includes a blocking member that prevents the photovoltaic module 300 from continuing to be conveyed forward, and a blocking drive member that drives the blocking member to move up and down or rotate.

[0037] The alignment component 3 aligns the photovoltaic module left and right. The alignment component 3 includes an alignment cylinder 31, a moving frame 32 driven by the alignment cylinder 31 to move left and right, and an alignment wheel 33 set on the moving frame 32.

[0038] To improve the versatility of the junction box calibration device 100 and adapt it to photovoltaic modules 300 of different sizes, the calibration component 3 is movably positioned left and right. The movable calibration component 3 is mounted on the frame 5 via a slider rail and secured with screws. To adjust the position of the calibration component 3, simply loosen the screws; after adjustment, tighten them again. The movable calibration component 3, mounted on the frame 5 via a slider rail, is automatically adjusted in position using a servo motor, allowing for one-button switching in the control system when changing photovoltaic modules of different sizes.

[0039] In other embodiments, the rear end of the conveying line 1 is also provided with a post-correction module for correcting the rear end of the photovoltaic module 300. The post-correction module is prior art, and the design in the prior art can be used, so there is no limitation here.

[0040] The junction box calibration mechanism 4 includes a first driving member 41, a first support plate 42 driven by the first driving member 41 to move up and down, a first pressing member 43 pressing the box body 201 of the junction box 200, a pressing plate 44 pressing the coil 202 of the junction box 200, and a toggle assembly 45 for adjusting the position of the coil 202 are provided below the first support plate 42. The toggle assembly 45 includes a second driving member 451 provided on the first support plate 42, a mounting base 452 driven by the second driving member 451 to rotate around a vertical axis, and a toggle rod 453 provided at the end of the mounting base 452. The pressing plate 44 is provided with an arc-shaped guide groove 441 for the toggle rod 453 to move.

[0041] The shape of the arc-shaped guide groove 441 is consistent with the movement path of the toggle lever 453, ensuring that the toggle lever 453 moves along a predetermined trajectory and accurately pushes the coil 202 into the inner side of the frame, ensuring the accuracy of the correction. In this embodiment, the angle of the arc-shaped guide groove 441 is 180°. In other embodiments, the angle and radius of the arc-shaped guide groove 441 can be set according to the actual situation and are not limited here. The height of the frame 400 is higher than the height of the photovoltaic module glass, and the frame 400 and the edge of the photovoltaic module glass form a groove for the coil 202 to be inserted. When actually performing the correction action on the junction box 200, the arc-shaped guide groove 441 is set towards the side of the frame 400 so that when the toggle lever 453 moves in the arc-shaped guide groove 441, it can push the coil 202 to the inner side of the frame 400, thereby allowing the coil 201 to be inserted into the inner side of the frame 400.

[0042] The first clamping member 43 is detachably mounted below the first support plate 42 via the first bracket 47, and is also detachably mounted below the first support plate 42 via a third fastener, so that the first clamping member 43 of different lengths and widths can be easily replaced for boxes 201 of different lengths and widths. The first clamping member 43 presses the lid at the top of the box 201 downwards.

[0043] In this embodiment, the first clamping member 43 is made of rubber, which can avoid damaging the box body 201. Moreover, the rubber surface has high friction, which can prevent the box body 201 from sliding or shifting, and can achieve stable clamping.

[0044] In this embodiment, the first bracket 47 includes a first connecting plate 471 connected to the first support plate 42 and a second connecting plate 472 detachably connected below the first connecting plate 471. A first clamping member 43 is detachably disposed at the bottom of the second connecting plate 472. The first connecting plate 471 is mounted on the first support plate 42 by a first fastener. The first connecting plate 471 and the first support plate 42 are provided with first mounting holes that mate with the first fastener. The second connecting plate 472 is mounted on the first connecting plate 472 by a second fastener. The first connecting plate 471 is provided with a second mounting hole 477 that mates with the second fastener. The second connecting plate 472 is provided with an oblong hole 476 that mates with the second fastener, and the oblong hole 476 extends vertically. The oblong hole 476 can adjust the position of the second connecting plate 472 and the position of the first clamping member 43 vertically, thereby adapting to boxes 201 of different heights and improving the versatility of the junction box calibration mechanism 4.

[0045] In other embodiments, the first bracket 47 includes only the second connecting plate 472. The upper end of the second connecting plate 472 is directly connected to the first support plate 42 through the second fastener. The second connecting plate 472 is also provided with a waist-shaped hole 476, which can also adjust the position of the first clamping member 43 up and down. Moreover, the first connecting plate 471 is omitted, which can reduce the assembly time and ensure the stability of the assembly.

[0046] The first fastener, the second fastener, and the third fastener are selected from screws, bolts, and pins, or fasteners of other structures, without limitation.

[0047] The clamping plate 44 is disposed below the first support plate 42 by a number of elastic components 46. The clamping plate 44 can elastically press against the coil 202 so that the coil 202 can move smoothly when the lever 453 moves the coil 202. The elastic components 46 provide flexible pressure and can adapt to the thickness difference of the coil 202.

[0048] The elastic component 46 includes a guide rod 461 whose lower end is fixed on the pressure plate 44 and whose upper end is movably disposed on the first support plate 42, a spring 462 sleeved on the outer periphery of the guide rod 461, and a bearing 463 disposed at the top of the guide rod 461. A bearing sleeve 464 is disposed on the first support plate 42. The guide rod 461 is disposed in the bearing sleeve 464 through the bearing 463. The lower end of the spring 462 abuts against the upper surface of the pressure plate 44 and the upper end abuts against the lower surface of the bearing sleeve 464.

[0049] In this embodiment, the junction box calibration mechanism 4 is mounted on the frame 5 via the mounting beam 7. There are two junction box calibration mechanisms 4 in total, located in front of and behind the mounting beam 7, which can simultaneously calibrate the position of two junction boxes 200. In other embodiments, the position and number of junction box calibration mechanisms 4 can be set according to the actual situation and are not limited here.

[0050] To improve the versatility of the junction box calibration device 100 and adapt it to junction boxes 200 in different positions, the junction box calibration mechanism 4 is movably mounted on the mounting beam 7, allowing it to move back and forth. The movable junction box calibration mechanism 4 is mounted on the mounting beam 7 via a slider rail and secured with screws. To adjust the position of the junction box calibration mechanism 4, simply loosen the screws; after adjustment, tighten them again. The movable junction box calibration mechanism 4, mounted on the mounting beam 7 via a slider rail, is driven by a servo motor to automatically adjust its position, enabling one-button switching in the control system when changing junction boxes 200 of different sizes.

[0051] To improve the versatility of the junction box calibration device 100 and adapt it to junction boxes 200 in different locations, the mounting beam 7 is movably mounted on the frame 5, allowing the junction box calibration mechanism 4 to move left and right. The movable mounting beam 7 can be mounted on the frame 5 via a slider rail and locked with screws for manual adjustment; or it can be automatically adjusted by using a servo motor to drive the mounting beam 7. The movable mounting method is the same as or similar to the movable mounting method of the junction box calibration mechanism 4, and will not be described in detail here.

[0052] In this embodiment, a junction box 200 is also provided in the middle of the photovoltaic module. However, the junction box 200 only has a box body 201 and no coil 202. Therefore, it is only necessary to be able to press the box body 201. Thus, a junction box correction device 100 also includes a pressing module 6. The pressing module 6 includes a pressing cylinder provided on the frame 5 and a second pressing member that is driven by the pressing cylinder to move up and down. The structure of the second pressing member is the same as or similar to the structure of the first pressing member 43, and will not be described in detail here.

[0053] The clamping module 6 is also movably mounted on the frame 5. Its movability is the same as or similar to that of the junction box calibration mechanism 4, and will not be described in detail here.

[0054] When using the junction box calibration device 100 provided in this solution, after the photovoltaic module is conveyed to its position via the conveyor line 1, the blocking component 2 first blocks the photovoltaic module from continuing to be conveyed forward, and the calibrating component 3 completes the calibration of the photovoltaic module. Part of the coil is on the surface of the photovoltaic module glass, and the other part rests on the frame 400. Figure 4As shown, the first driving component 41 drives the first support plate 42 to descend, and the first pressing component 43 presses against the box body 201 of the junction box 200, achieving secondary pressing of the box body 201. Simultaneously, the pressing plate 44 elastically presses against the coil 202 of the junction box 200. At this time, the actuating lever 453 is located inside the coil 202. The second driving component 451 drives the mounting base 452 to rotate the actuating lever 453 counterclockwise or clockwise, completely moving the coil onto the surface of the photovoltaic module glass. Figure 5 As shown, next, the second driving component 451 drives the mounting base 452 to rotate the toggle lever 453 in the opposite direction, that is, clockwise or counterclockwise, to completely move the coil 202 to the side of the frame 400, so that one side of the coil 202 is inserted into the inside of the frame 400, as shown. Figure 6 As shown, the clamping of the box 201 and the correction of the position of the coil 202 are completed simultaneously, thereby realizing the correction of the position of the junction box 200. After the correction is completed, the first driving component 41 drives the first support plate 42 to rise, the first clamping component 43, the clamping plate 44, and the toggle rod 453 are reset, and the corrected photovoltaic module 300 of the junction box 200 flows out.

[0055] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
