[0029] The limiting mechanism comprises: first limiting members 4, second limiting members 5, angle plates 12 and support plates, the first limiting members 4 are two groups and can be relatively moved along a first direction, the second limiting members 5 are two groups and can be relatively moved along a second direction, the first limiting members 4 and the second limiting members 5 are staggered, the angle plates 12 are movably connected to adjacent first limiting members 4 and second limiting members 5 respectively, and the support plates are arranged on the angle plates 12 to support the angle profiles to be riveted.

[0030] The crimping assembly comprises: a two-axis driving assembly and a riveting head 55, the riveting head 55 is connected with the two-axis driving assembly, and the two-axis driving assembly is used for driving the riveting head 55 to lift or crimp the rivets to be riveted.

[0031] The full-screen photovoltaic module frame riveting machine comprises two-axis driving assemblies and a riveting head 55, the riveting head 55 is connected with the two-axis driving assemblies, the two-axis driving assemblies are used for driving the riveting head 55 to lift or crimp the rivets to be riveted, one axis of the two-axis driving assemblies is used for driving the riveting head 55 to lift to a riveting height, and the other axis is used for driving the riveting head 55 to crimp the rivets to complete riveting; after riveting is completed, the two-axis driving assemblies drive the riveting head 55 to retreat and lift to retract, so as to avoid shielding the frame, through the above setting, the frame can be automatically riveted, the precision of riveting direction guidance is improved, and different riveting equipment does not need to be specially designed for different sizes of the frame, and the frame of different sizes can be applied.

[0032] With Figure 2 as the reference, the first direction is the left-right direction, the second direction is the up-down direction, and the third direction is the up-down direction; when the frame length is too long, the first limiting members 4 and the second limiting members 5 are arranged with the support plates along the length direction, so that the frame is more stably supported, in the embodiment, the first limiting members 4 are long edges 2, the second limiting members 5 are short edges 1, and the length of the first limiting members 4 is greater than that of the second limiting members 5.

[0033] Referring to Figures 2-3As shown, the device further comprises a conveying mechanism, which comprises a conveying belt and a jacking assembly 8 connected to the output end of the conveying belt, and the jacking assembly 8 is used to drive the conveying belt to move in the third direction, and the conveying mechanism is used to convey the frame. The conveying belt is the main bearing and transmission component of the conveying mechanism, which can stably bear and convey the frame or the completed frame of the full-screen assembly with riveted corners. The conveying belt is driven by the jacking assembly 8 to rise or fall in the third direction, so that the conveying belt rises to a height suitable for the limiting mechanism or falls to a suitable height to avoid interference with the first limiting member 4 and the second limiting member 5.

[0034] Referring to Figure 3 As shown, the conveying belt is arranged in the second direction, and the conveying belt is rotatably connected with a roller 10 on both sides in the first direction, so that the width of the conveying belt is extended by the roller 10 to avoid the large-size frame from falling due to imbalance. The roller 10 is not located at the four corners of the frame during riveting, so as to avoid the blocking of the roller 10 to the angle plate 12 or the riveting head 55. The roller 10 corresponds to the long side 2 of the frame.

[0035] Referring to Figure 2 As shown, the riveting machine comprises a rack, each of the first limiting member 4 and the second limiting member 5 is movably connected to the rack through a first sliding pair assembly, and the rack is provided with a first driving member for driving at least one of the first limiting member 4 and the second limiting member 5 to move. The first sliding pair assembly movably connects the first limiting member 4 and the second limiting member 5 to the rack, which is commonly composed of a guide rail and a sliding block. There are at least four groups of first sliding pair assemblies, each of which is arranged on one first limiting member 4 or one second limiting member 5. Each group comprises two sliding rails and corresponding sliding blocks at both ends of each limiting member, which provides reliable limiting support for the frame. The rack is provided with a passage 6 adapted to the conveying belt on both sides.

[0036] Referring to Figure 3 As shown, a stop mechanism 7 is arranged on the transmission path of the conveying belt, which comprises a fourth cylinder assembly and a roller. The fourth cylinder assembly is arranged on the rack, and the roller can be blocked or avoided by the fourth cylinder assembly. During normal operation of the device, the frame is conveyed by the conveying belt, the fourth cylinder assembly is in the initial state, the piston rod is retracted, and the roller is in the avoiding position, that is, the roller does not protrude onto the transmission path of the conveying belt. When the frame needs to be stopped, the roller is driven to rise by the fourth cylinder assembly to prevent the frame from being driven by the conveying belt, which is convenient for the operator or the mechanical hand to take or put the frame from the conveying belt.

[0037] Referring to Figure 3As shown, the rack is also provided with a third cylinder assembly 9, which is respectively used to drive the first limiting piece 4 and the second limiting piece 5 to approach or move away from the workpiece to be chamfered, the number and position of the cylinders of the third cylinder assembly 9 correspond to the slide rails and the slide blocks of the first sliding pair assembly, so as to balance the independent pushing of each first limiting piece 4 and second limiting piece 5 from both ends, in this embodiment, the first direction and the second direction are perpendicular, and the frame is a rectangular frame.

[0038] Referring to Figure 4 As shown, the angle plate 12 is slidably connected to the adjacent first limiting piece 4 and second limiting piece 5 through the second sliding pair assembly, the support plate protrudes from the angle plate 12 and forms a stepped surface with the angle plate 12 for supporting the angle profile to be riveted, when it is necessary to rivet the angle of the frame of the full-screen assembly of different sizes, the positions of the first limiting piece 4 and the second limiting piece 5 are driven to change the distance therebetween. Since the angle plate 12 is slidably connected to the first limiting piece 4 and the second limiting piece 5 through the second sliding pair assembly, the angle plate 12 will slide on the slide rail accordingly with the movement of the first limiting piece 4 and the second limiting piece 5, the number of the angle plate 12 is four and is arranged at the staggered positions of the first limiting piece 4 and the second limiting piece 5, and the number of the slide rails and the slide blocks in the second sliding pair assembly is eight. The protrusion of the support plate enables the profile to be stably placed on the stepped surface, and the stepped surface provides gravitational support for the profile.

[0039] Referring to Figure 5 As shown, the two-axis driving assembly comprises a support frame 51 movably connected to the first limiting piece 4 in the second direction, a first cylinder 52 fixedly connected to the support frame 51, and a second cylinder 53 connected to the first cylinder 52, the second cylinder 53 is movably connected to the support frame 51 in the first direction, the riveting head 55 is connected to the output end of the second cylinder 53, the second cylinder 53 drives the riveting head 55 to rise and fall until the riveting head 55 corresponds to the rivet on the frame, the second cylinder 53 is driven by the first cylinder 52 and moves in the second direction, so that the riveting head 55 can rivet the rivet, specifically, the support frame 51 movably connects with a movable frame 54 through a sliding pair, and the second cylinder 53 is installed on the movable frame 54. Since in this embodiment, the frame corresponding to the first limiting piece 4 is the long side 2 and extends in the second direction, and the riveting direction of the rivet is the second direction, it is only necessary to rivet the angle side 3 and the long side 2 profile in the second direction.

[0040] Referring to Figure 4 As shown, the angle plate 12 comprises a first plate body and a second plate body, the first plate body and the second plate body are fixedly connected, the first plate body and the second plate body are slidably connected to the first limiting piece 4 and the second limiting piece 5 through the second sliding pair assembly, the planes where the first plate body and the second plate body are located are perpendicular, and the extension directions of the first limiting piece 4 and the second limiting piece 5 are respectively located in the planes where the first plate body and the second plate body are located.

[0041] The support frame 51 is connected to the first limiting member 4 through the third sliding pair assembly, and the sliding rails and sliding blocks of the third sliding pair are arranged on the outer side of the first limiting member 4, and the corresponding sliding rails and sliding blocks of the second sliding pair are arranged on the inner side of the first limiting member 4 at the upper and lower ends. Since the support frame 51 is connected to the angle plate 12, the support member clamps the limiting member 4 on the inner and outer sides of the first limiting member 4 along the first direction, and also presses along the second direction when the rivet is pressed. The third sliding pair assembly and the first sliding pair assembly cooperate to provide stable support for the first cylinder 52. Since the rivet pressing head 55 moves inwardly for rivet pressing, the third sliding pair provides the main support force. In this embodiment, the sliding rails and sliding blocks in each sliding pair assembly are fixedly connected to the two parts that slide relative to each other.

[0042] Referring to Figure 4 As shown in the figure, the first limiting member 4 is provided with a relief hole 11, which is arranged along the second direction and has a size suitable for the size of the second limiting member 5. When the second limiting member 5 gradually approaches or moves away from the first limiting member 4, since the relief hole 11 is arranged along the second direction and has a size suitable for, i.e. larger than, the size of the second limiting member 5, the second limiting member 5 can smoothly pass through the relief hole 11 on the first limiting member 4 during movement, without interfering with the first limiting member 4, so that the sizes of the first limiting member 4 and the second limiting member 5 are adjusted to be enclosed outside the frame of the corresponding size, and the angle plate 12 is always in the four-corner position.

[0043] Obviously, the above embodiments are only examples for clear illustration, and are not a limitation on the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
