[Specific implementation method]

[0024] Embodiment 1:

[0025] Please refer to Figure 1-Figure 5 The present embodiment is an automatic riveting device 100 for the corners of a photovoltaic component without an A-side frame, which includes a lifting conveyor line 1, a correction module 2 for correcting the position of the photovoltaic components on the lifting conveyor line 1, a support platform 3 for lifting the photovoltaic components on the lifting conveyor line 1 upward, and a corner riveting mechanism 4 for riveting the corners at the four corner areas of the photovoltaic components.

[0026] The corner riveting mechanism 4 includes two submodules located on opposite sides of the lifting conveyor line 1, each of which includes a first motor 41, a first support plate 42 driven by the first motor 41 to move left and right, a second motor 43 fixed on the first support plate 42, and two corner riveting modules 44 driven by the second motor 43 to move forward and backward. The first motor 41 drives the first support plate 42 to move left and right, and adjusts the spacing between the two submodules to adapt to photovoltaic modules of various sizes. The second motor 43 drives the two corner riveting modules 44 to move closer to or away from each other, so as to achieve the position switching of the corner riveting modules 44 between the avoidance position and the working position. The corner riveting module 44 includes a second support plate 441 driven by the second motor 43 to move forward and backward, a cylinder 442 and a corner support seat 443 fixed on the second support plate 441, and a riveting head 444 driven by the cylinder 442 to move close to or away from the corner support seat 443.

[0027] The corner support seat 443 includes a support flat plate 4431 and a corner stopper plate 4432 for limiting the position of the corner of the photovoltaic module frame. The corner support seat 443 is L-shaped, with its opening facing outward, and the riveting head 444 is located on the opening side of the corner support seat 443 and is aligned with the lower half of the corner of the photovoltaic module frame. During riveting, the corner of the photovoltaic module sits on the corner support seat 443, and the riveting head 444 is located below the photovoltaic module so that the riveting head 444 can be aligned with the lower half of the corner of the frame for riveting.

[0028] The riveting head 444 includes a horizontal support plate 4441, one end of which extends to align with the right-angle intersection of the corner support seat 443, and has two mutually perpendicular action surfaces 4442 corresponding to the corner frames at the end, and the two action surfaces 4442 are provided with riveting protrusions 4443 that rivet the frame body and the internal corner code together. The frame of the photovoltaic module is an aluminum profile, which has a limited thickness and high riveting precision requirements. If the riveting pressure is too large, the frame may be riveted through; if the riveting pressure is too small, the connection strength between the two adjacent frames does not meet the design requirements, and it is easy to loosen. Therefore, the size of the riveting pressure needs to be accurately controlled and set. In addition, in order to improve the riveting efficiency, the present embodiment uses four corner riveting modules 44 to perform riveting operations synchronously. Since the frame has been assembled into a rectangular frame structure, the four corner riveting modules 44 need to be highly synchronized when riveting. If the synchronization is not high, the corners of the frame may be disassembled.

[0029] In order to ensure the synchronization of the four corner riveting modules 44, in this embodiment, the oil cylinders 442 in the four corner riveting modules 44 are controlled by separate control valves so that each oil cylinder 442 can be accurately and reliably controlled. Compared with full valve control, this can effectively prevent the four oil cylinders 442 from having pressure instability or asynchronous start and stop during riveting drive.

[0030] In addition, in order to ensure that the riveting pressure of the corner riveting module 44 meets the riveting requirements, this embodiment fully considers the mechanical performance parameters of the photovoltaic module frame and the material thickness of the frame riveting position when designing the pressure of the cylinder 442, and combines the area of ​​the riveting protrusion 4443 to design the optimal riveting force parameters and the riveting stroke parameters of the cylinder 442 during riveting to ensure the riveting quality.

[0031] In this embodiment, since the rivet head 444 needs to rivet two right-angled surfaces of the corner at the same time, the setting angle of the rivet head 444 and the setting angle of the corner support seat 443 need to be accurately set, and the end of the rivet head 444 needs to be strictly aligned with the right-angle intersection of the corner support seat 443, that is, the setting angle of the corner support seat 443 and the rivet head 444 must be strictly controlled to be distributed at a 45-degree angle. In order to ensure that the setting angles of the corner support seat 443 and the rivet head 444 are accurate, in this embodiment, the second support plate 441 is provided with a first bracket 445 and a second bracket 446 of different heights, the height of the first bracket 445 is higher than the height of the second bracket 446, the first bracket 445 is provided with a first angle adjustment component 447 for adjusting the setting angle of the corner support seat 443, and the second bracket 446 is provided with a second angle adjustment component 448 for adjusting the setting angle of the rivet head 444.

[0032] The first angle adjustment assembly 447 includes a first support base plate 4471 disposed on the first bracket 445 and at least four first adjustment top screws 4472 symmetrically disposed on opposite sides of the first support base plate 4471; the corner support seat 443 is disposed at the end of the first support base plate 4471. The first support base plate 4471 has a floating space in a first direction relative to the first bracket 445, and the first direction is perpendicular to the driving direction of the oil cylinder 442 and is a horizontal direction. The four first adjustment top screws 4472 are divided into two pairs and are disposed on opposite sides of the first support base plate 4471. By adjusting the telescopic length of the first adjustment top screws 4472, the horizontal angle of the first support base plate 4471 can be adjusted, and then the angle adjustment of the corner support seat 443 can be achieved.

[0033] The second angle adjustment assembly 448 includes a second support base plate 4481 disposed on the second bracket 446 and at least four second adjustment top screws 4482 symmetrically disposed on opposite sides of the second support base plate 4481; a slide rail 449 is disposed on the second support base plate 4481, a slider 4410 is slidably disposed on the slide rail 449, and the riveting head 444 is installed at the end of the slider 4410; one end of the oil cylinder 442 is hingedly disposed on the second support base plate 4481 and the piston end is hingedly disposed with the slider 4410. The second support base plate 4481 has a floating space in the second direction relative to the second bracket 446, and the second direction is perpendicular to the driving direction of the oil cylinder 442 and is a horizontal direction. The four second adjustment top screws 4482 are divided into two pairs and are respectively disposed on opposite sides of the second support base plate 4481. By adjusting the telescopic length of the second adjustment top screws 4482, the horizontal angle of the second support base plate 4481 can be adjusted, and then the angle adjustment of the entire module of the oil cylinder 442 and the riveting head 444 can be achieved.

[0034] The first supporting bottom plate 4471 and the second supporting bottom plate 4481 have floating spaces perpendicular to the driving direction of the oil cylinder 442 relative to the first bracket 445 and the second bracket 446 respectively. In order to realize the floating spaces, the present embodiment designs the installation structure. Specifically, a plurality of threaded holes 4451 are provided on the first bracket 445 and the second bracket 446, and mounting step holes 44711 corresponding to the positions of the threaded holes 4451 are provided on the first support base plate 4471 and the second support base plate 4481. The first support base plate 4471 and the second support base plate 4481 are both locked by screws 44712 ​​passing through the mounting step holes 44711 and screwed into the threaded holes 4451; the aperture of the mounting step hole 44711 is larger than the diameter of the screw 44712, or the mounting step hole 44711 is a waist-shaped step hole, so that the first support base plate 4471 relative to the first bracket 445 and the second support base plate 4481 relative to the second bracket 446 have a floating degree of freedom perpendicular to the driving direction of the cylinder 442.

[0035] By adjusting the angle of the corner support seat 443 through the first angle adjustment component 447, it can be ensured that before riveting, the right-angled side of the photovoltaic component can be completely fitted into the corner limit plate 4432 for positioning, thereby ensuring the accurate position of the right-angled side of the photovoltaic component, providing a prerequisite for subsequent precise riveting; by adjusting the angle of the riveting head 444 through the second angle adjustment component 448, it can be ensured that the two action surfaces 4442 at the end of the riveting head 444 can be parallel to the riveting surfaces corresponding to the corner frame. When the riveting head 444 is riveting, the riveting protrusions 4443 on the two action surfaces 4442 can effectively act on the above-mentioned riveting surfaces, ensuring that each riveting surface obtains sufficient riveting pressure, effectively preventing the phenomenon that one of the riveting surfaces is understressed and the other riveting surface is overstressed, ensuring that the riveting process is reliable and effective, and improving the riveting quality.

[0036] In order to ensure that the oil cylinder 442 can smoothly drive the riveting head 444 to perform telescopic movement, an escape space (not shown in the figure) is formed inside the first bracket 445, and the slider 4410 extends outward through the escape space to below the corner support seat 443.

[0037] Since the frame heights of some photovoltaic modules are different, in order to match the riveting of frames of different heights, the riveting head 444 is set on the slider 4410 so that the upper and lower positions can be adjusted. A support plate 4411 is set on the lower surface of the slider 4410, and a through hole (not shown in the figure) is set on the slider 4410 body, which is aligned with the support plate 4411 and passes through the through hole from top to bottom. The riveting head 444 is located on the support plate 4411 and passes through the through hole upward. A third adjusting top screw 4412 for adjusting the height of the riveting head 444 is set on the support plate 4411; the height of the riveting head 444 can be adjusted by adjusting the ejection height of the third adjusting top screw 4412. The slider 4410 is also provided with a locking screw (not shown in the figure) for laterally pressing the riveting head 444.

[0038] In this embodiment, the support platform 3 includes a plurality of support blocks distributed along the long sides of the photovoltaic module. The plurality of support blocks are located on both sides of the lifting conveyor line 1 and do not interfere with the lifting conveyor line 1 .

[0039] The working principle of the automatic riveting device 100 for corners of a photovoltaic module without an A-side frame in this embodiment is as follows: the photovoltaic module with a frame is transported by the lifting conveyor line 1 to the corner riveting station, the alignment module 2 aligns the positions of the four sides of the photovoltaic module, the lifting conveyor line 1 carries the photovoltaic module downward, transfers the photovoltaic module to the support platform 3, the lifting conveyor line 1 continues to descend, the photovoltaic module leaves the surface of the lifting conveyor line 1 and sits on the support platform 1; the first motor 41 and the second motor 43 in the two submodules work together to drive the four corner riveting modules 44 to approach the four corners of the photovoltaic module; after moving to the right position, the four corners of the photovoltaic module are respectively located on the corner support seats 443 of the four corner riveting modules 44, and the positions are limited by the corner limit plates 4432, the oil cylinder 442 is started, and the riveting head 444 is driven to approach the corner support seat 443, and the riveting protrusion 4443 at the end of the riveting head 444 is used to rivet the frame body and the internal corner code together to complete the riveting of the frame corners.
