Description

Technical Field

[0001] The utility model belongs to the technical field of profile bending equipment production, and particularly relates to a profile bending mechanism.

Background Art

[0002] A photovoltaic module is a device that converts solar energy into electrical energy. After lamination, four frames need to be assembled around the conventional photovoltaic module to form an aluminum frame structure. With the iterative update of the product structure, a new type of photovoltaic module without an A-frame appears, and only a rectangular light frame needs to be buckled around the glass. The frame is generally made of lightweight alloy material, and the incoming material is generally long strip-shaped, so it needs to be bent and then assembled into a closed structure.

[0003] In the prior art, patent CN108581498B discloses an automatic bending and welding device for door and window pipes. In this device, only a cylinder is used to push the profile body perpendicular to the extending direction of the profile to cause a 90° bend. On the one hand, the bending angle of the profile can only be 90°, and the bending angle range is limited. On the other hand, the bent section of the profile is in a cantilever state during bending. After bending, the height position and plane position of the bent section cannot be reliably and effectively guaranteed, which is not conducive to subsequent precise assembly and welding after the frame is bent.

[0004] Therefore, it is necessary to provide a new profile bending mechanism to solve the above technical problems.

[0009] Further, in the initial state, the second bending end clamping assembly is arranged side by side and collinearly with the first bending end clamping assembly on the rotating bracket, and the first bending end clamping assembly, the second bending end clamping assembly, and the first side clamping assembly together form a linear support and clamping platform.

[0010] Further, an adjusting support rod with an adjustable extension length is arranged on the rotating bracket, and at least one of the outermost first side clamping assemblies is arranged on the adjusting support rod.

[0011] Further, a position adjusting module is further included; the position adjusting module includes a vision camera for obtaining the bending position of the profile, a fourth support plate, a second motor fixed on the fourth support plate, a fifth support plate driven by the second motor to perform horizontal motion, and a second side clamping assembly fixed on the fifth support plate and clamping the unbent section of the profile.

[0012] Further, chamfers are arranged on the opposite sides of the first limit block in the first bending end clamping assembly and the first limit block in the second bending end clamping assembly; in the initial state, the two first limit blocks are adjacent to each other on the chamfered side, and the chamfers together form a V-shaped structure; the vision camera is aligned with the V-shaped structure.

[0014] Further, the second side clamping assembly includes a second limit block fixed on the fifth support plate, a pressing plate for pressing the vertical side plate of the frame against the second limit block, a rolling wheel for pressing the horizontal plate surface of the frame against the second limit block, a second air cylinder for driving the pressing plate to move horizontally, and a third air cylinder for driving the rolling wheel to move horizontally.

[0015] Further, the structure of the first side clamping assembly is the same as that of the first bending end clamping assembly or the second side clamping assembly.

[0016] Compared with the prior art, the beneficial effects of a profile bending mechanism of the present utility model are as follows: A first bending end clamping assembly for fixing the end of the unbended section (frame A) of the profile is provided to fix the bending end of frame A. A rotatable second bending end clamping assembly and a first side clamping assembly are provided.

Specific implementation manner

[0030] Embodiment 1:

[0031] Please refer to Figures 1 - 5 , this embodiment is a profile bending mechanism 100, which includes a first support plate 1, a fixed support 2 fixed on the first support plate 1, a first bending end clamping assembly 3 fixed on the fixed support, a rotating bracket 5 with one end rotatably arranged on the fixed support 2 and the other end driven by a bending drive module 4 to rotate, a second bending end clamping assembly 6 arranged on the rotating bracket 5 and close to the first bending end clamping assembly 3, and several first side clamping assemblies 7 arranged on the rotating bracket 5 to clamp the border of the bent section.

[0032] The first bending end clamping assembly 3 is used to clamp the end position of one side border A at the profile bending position, and the second bending end clamping assembly 6 is used to clamp the end position of the other side border B at the profile bending position. During bending, the bending drive module 4 drives the rotating bracket 5 to drive the second bending end clamping assembly 6 and the first side clamping assemblies 7 to rotate, thereby driving the border B to bend at an arbitrary angle relative to the border A, and its bending angle is controlled by the driving of the bending drive module 4.

[0033] The first bending end clamping assembly 3 and the second bending end clamping assembly 6 have the same structure, and both include a first limit block 31, a pressing member 32 for pressing the border against the first limit block 31, and a first cylinder 33 for driving the pressing block 32 to move horizontally. The pressing member 32 can adopt a roller structure, or an L-shaped pressing plate, or a flat pressing plate, or a profiling pressing block, etc., and is preferably a roller structure.

[0034] The bending drive module 4 includes a first motor 41 fixed on the first support plate 1, a second support plate 42 driven by the first motor 41 to perform horizontal linear motion, a pair of first slide rails 43 fixed on the second support plate 42 and extending perpendicular to the motion direction of the second support plate 42, and a third support plate 44 slidably arranged on the first slide rails 43; one end of the rotating bracket 5 is rotatably arranged on the fixed support 2 through a first rotating shaft 51, and the other end is rotatably connected to the third support plate 44 through a second rotating shaft 52, and both the first rotating shaft 51 and the second rotating shaft 52 are arranged vertically.

[0035] The first motor 41 drives the second support plate 42 to perform a horizontal linear motion, thereby driving the rotating bracket 5 to rotate around the first rotating shaft 51. In the initial state, the second bending end clamping assembly 6 is arranged side by side and collinearly with the first bending end clamping assembly 3 on the rotating bracket 5, and the first bending end clamping assembly 3, the second bending end clamping assembly 6, and the first side clamping assembly 7 together form a linear support clamping platform so that the linear frame can be placed on this support clamping platform. In other embodiments, the setting position of the first side clamping assembly 7 can also be arranged in a profiling manner according to the profile shape of the frame to be bent. Under the driving action of the first motor 41, the rotating bracket 5 is driven to rotate by a set angle (such as 120°, 90°, 60°, 45°, etc.), and the second bending end clamping assembly 6 and the first side clamping assembly 7 arranged on the rotating bracket 5 rotate synchronously to clamp the frame B and bend it by a set angle.

[0036] The number of the first side clamping assemblies 7 can be flexibly set according to the length of the bent section of the frame B. If the section of the frame B is short, only one first side clamping assembly 7 can be set. If the length is long, multiple first side clamping assemblies 7 can be set.

[0037] In order to meet the clamping requirements of frames B with various different length specifications, the rotating bracket 5 is provided with an adjusting support rod 53 with an adjustable extending length. At least one first side clamping assembly 7 arranged on the outside is arranged on the adjusting support rod 53, and the position of the first side clamping assembly 7 is adjusted by the adjusting support rod 53 to match frames B with various different length specifications. Specifically, a pair of second sliding rails 54 are arranged on the rotating bracket 5, and the adjusting support rod 53 is horizontally slidably arranged on the second sliding rails 54 through a slider. One end of the adjusting support rod 53 extends out of one end of the rotating bracket 5 in a cantilever manner, and the position of the first side clamping assembly 7 arranged on the adjusting support rod 53 can be adjusted by adjusting its extending length.

[0038] In order to improve the accuracy of the profile bending position, this embodiment is also configured with a profile position adjustment function. Specifically, this embodiment further includes a position adjustment module 8. The position adjustment module 8 includes a vision camera 81 for obtaining the profile bending position, a fourth support plate 82, a second motor 83 fixed on the fourth support plate 82, a fifth support plate 84 driven by the second motor 83 to perform a horizontal motion, and at least one second side clamping assembly 85 fixed on the fifth support plate 84 and clamping the unbent section of the profile. The second motor 83 drives the second side clamping assembly 85 to clamp the profile closer to or farther away from the first bending end clamping assembly 3 to ensure that the profile bending position is exactly aligned with the set bending position between the first bending end clamping assembly 3 and the second bending end clamping assembly 6.

[0039] The first limit block 31 in the first bending end clamping assembly 3 and the first limit block 31 in the second bending end clamping assembly 6 are provided with chamfers on the opposite sides. In the initial state, the two first limit blocks 31 are adjacent to each other on the chamfer side, and the chamfers together form a V-shaped structure 34. The V-shaped structure 34 can be used as a reference for aligning the bending point of the frame. The vision camera 81 is fixed on the first support plate 1 and is aligned with the intersection area of the first bending end clamping assembly 3 and the second bending end clamping assembly 6 - the V-shaped structure 34.

[0040] In order to adapt to frames A of various different length specifications, in this embodiment, a pair of third slide rails (not marked in the figure) extending along the extension direction of the frame A are provided at the bottom of the first support plate 1. The first support plate 1 is adjustably arranged on the third slide rails. According to the length of the frame A, the position of the first support plate 1 is adjusted so that the first bending end clamping assembly 3 can be aligned with the bending end of the frame A for clamping.

[0041] In this embodiment, the second side clamping assembly 85 includes a second limit block 851 fixed on the fifth support plate 84, a pressing plate 852 for pressing the vertical side plate of the frame A against the second limit block 851, a rolling wheel 853 for pressing the horizontal plate surface of the frame A against the second limit block 851, a second cylinder 854 for driving the horizontal movement of the pressing plate 852, and a third cylinder 855 for driving the horizontal movement of the rolling wheel 853.

[0042] In other embodiments, the second side clamping module 85 can also have the same structure as the first bending end clamping assembly 3.

[0043] The structure of the first side clamping assembly 7 can be the same as the structure of the first bending end clamping assembly 3 or the same as the structure of the second side clamping assembly 85.

[0044] For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
