Description

Technical Field

[0001] The present invention belongs to the technical field of laser cutting, and particularly relates to a cutting device for processing and cutting photovoltaic brackets. Background Art

[0002] Photovoltaic brackets are support structure systems used for installing and fixing solar photovoltaic panels. They play a crucial role in solar power generation systems. They not only ensure the safety and stability of the photovoltaic panels but also can adjust the angle of the photovoltaic panels according to actual needs to optimize the reception efficiency of sunlight, thereby improving the power generation efficiency of the entire system. In photovoltaic brackets, C-shaped steel of the photovoltaic bracket is the main component for installing the photovoltaic panels. According to the installation requirements of different numbers of photovoltaic panels, it is necessary to use cutting equipment to cut the C-shaped steel of the photovoltaic bracket into different lengths. However, the existing cutting equipment for C-shaped steel of photovoltaic brackets has the following problems: 1. When cutting the existing C-shaped steel of photovoltaic brackets, it is usually cut using a laser cutting machine. However, during cutting, usually only one C-shaped steel of the photovoltaic bracket can be cut at a time, and the cutting efficiency is low.

[0003] 2. When cutting the existing C-shaped steel of photovoltaic brackets, clamping and fixing are usually required. The common clamping method is to use a method of clamping in the middle on both sides. When clamping in this way, there is no pressing force from top to bottom. And during cutting, usually one side of the welding area is clamped using a fixture, and the clamping stability is poor. During cutting, the situation of the steel shaking easily occurs, reducing the cutting accuracy.

[0004] 3. During the laser cutting process of the C-shaped steel of the photovoltaic bracket, when cutting the side wall of the C-shaped steel of the photovoltaic bracket, the laser stays for a long time, which will cause a small amount of slag and oxides to appear on the cutting surface, so grinding is required. After the existing equipment cuts the C-shaped steel of the photovoltaic bracket, grinding needs to be carried out manually or using a separate grinding device. It is difficult to form the cutting and grinding in one step, and the working efficiency is low. Summary of the Invention

A third spring 657 is sleeved on the lower part of the crimping rod 658, and the third spring 657 is arranged between the second mounting plate 654 and the crimping block 656.

[0030] Please refer to Figure 5 and Figure 6 , the side clamping assembly 66 includes limit sliding grooves 662 symmetrically opened on the second mounting plate 654 in the front and back. A clamping arm 664 is slidably connected inside the limit sliding groove 662. A connecting block 663 is fixedly installed at the top of the clamping arm 664. A second rack 661 meshing with the second gear 652 is fixedly installed at the top of the connecting block 663.

The clamping block 665 is detachably installed, and clamping blocks 665 with different thicknesses are replaced according to the C-shaped steel of photovoltaic brackets with different clamped sizes.

[0031] During use, after the positioning and blocking mechanism 9 is used to block and limit the C-shaped steel of the photovoltaic bracket, the first hydraulic cylinder 611 is started at this time. The output end of the first hydraulic cylinder 611 contracts, driving the fixed head 612 and the first limiting slide rail 613 thereon to move downward, and then synchronously driving the first limiting slider 615 and the first mounting plate 62 thereon to move downward.

The second gear 652 drives the second rack 661 and the connecting block 663 thereon to move centrically, synchronously driving the clamping arm 664 and the clamping block 665 thereon to move centrically, and using the clamping block 665 to clamp and fix the side of the C-shaped steel of the photovoltaic bracket, realizing the secondary clamping and fixing of the C-shaped steel of the photovoltaic bracket, realizing the stable clamping of the C-shaped steel of the photovoltaic bracket, and using the multi-point clamping mechanism 6 to simultaneously clamp both sides of the cutting area of the C-shaped steel of the photovoltaic bracket.

[0032] Please refer to Figure 2 、 Figure 10 and Figure 11 As shown in FIGS.

[0033] After stably clamping multiple C-shaped steels of the photovoltaic support, the laser cutting head 2 and the electric slide rail 3 are started at this time. The electric slider 10 on the electric slide rail 3 moves from back to front, synchronously driving the laser cutting head 2 to move from back to front. The laser cutting head 2 is used to sequentially perform laser cutting on multiple C-shaped steels of the photovoltaic support from back to front, and synchronously drive the automatic locking and releasing mechanism 5 to move from back to front. After cutting is completed, the output end of the second hydraulic cylinder 97 extends, synchronously driving the connecting plate 92 and the baffle 91 thereon to move upward, releasing the blocking and limiting of the C-shaped steel of the photovoltaic support, and at the same time releasing the contact between the pushing mechanism 12 and the C-shaped steel of the photovoltaic support.

[0034] Please refer to Figure 2 , Figure 7 , Figure 8 and Figure 9 , the grinding mechanism 8 includes two second limiting slide rails 81 symmetrically and fixedly connected to the mutually close sides of the first roller conveyor 1 and the second roller conveyor 7. Two second limiting sliders 83 are slidably connected to the two second limiting slide rails 81. A grinding wheel 82 is rotatably installed between the two second limiting sliders 83. A third gear 89 is fixedly sleeved on one side of the rotating shaft of the grinding wheel 82. A U-shaped mounting frame 84 is fixedly installed in common on the front sides of the two second limiting sliders 83. A support rod 85 is fixedly installed on the front side of the top of the U-shaped mounting frame 84. A top rod 86 is fixedly installed on the top of the support rod 85. First inclined grooves are symmetrically opened on the left and right sides of the rear side of the top rod 86, and a connecting rod 87 is fixedly installed at the center of the rear side of the top rod 86. A clamping head 88 is fixedly installed on the rear side of the connecting rod 87. A fillet is opened on the rear side of the clamping head 88. Stopper blocks are fixedly installed at both the front and rear ends of the second limiting slide rail 81. A third rack 80 meshing with the third gear 89 is installed at the bottom of the second limiting slide rail 81 on the left side through a U-shaped fixing frame. A fourth spring (not shown in the figure) is provided between the second limiting slider 83 and the rear end of the second limiting slide rail 81, and the fourth spring is used for the automatic reset of the second limiting slider 83.

[0035] When the clamping arm 57 in the automatic locking and releasing mechanism 5 moves to fit with the clamping head 88, the fillet on the clamping head 88 fits with the guiding groove 55. Then, the clamping arm 57 continues to move from back to front, squeezing the guiding groove 55, driving the clamping arm 57 to rotate around the fixed pin 56, and simultaneously compressing the first spring 52. When the clamping head 88 passes over the guiding groove 55, under the restoring force of the first spring 52, the locking groove 54 is clamped and locked with the clamping head 88, thereby using the two clamping arms 57 to lock and fix the clamping head 88. After locking, at this time, under the action of the electric slide rail 3 and the electric slider 10, the automatic locking and releasing mechanism 5 and the clamping head 88 are driven to move backward synchronously, and at the same time, the connecting rod 87 and the ejector rod 86 thereon are driven to move backward. At this time, the first inclined groove on the ejector rod 86 fits with the second inclined groove on the L-shaped rod 64. With the continuous backward movement, by squeezing, the two L-shaped rods 64 and the two fixing rods 67 thereon are driven to move away from each other, and at the same time, the first mounting plate 62 and the L-shaped fixing plate 63 thereon are driven to move away from each other, synchronously realizing the separation movement of the top pressing assembly 65, the side clamping assembly 66 and the clamped cut C-shaped steel of the photovoltaic bracket thereon, realizing the automatic separation of the C-shaped steel of the photovoltaic bracket from the cutting surface. At this time, as the electric slider 10 continues to move backward, the ejector rod 86 and the support rod 85 thereon are driven to move backward, and at the same time, the U-shaped mounting bracket 84 and the second limit slider 83 thereon are driven to move backward, then driving the grinding wheel 82 to move backward, synchronously driving the third gear 89 to move backward. At the same time, since the third gear 89 meshes with the third rack 80, during the backward movement, the grinding wheel 82 is driven to rotate, and the rotating grinding wheel 82 is used to automatically grind the cutting surface, eliminating the need for subsequent manual grinding, realizing the integrated clamping, cutting and automatic grinding of multiple C-shaped steels of photovoltaic brackets, with high automation and high working efficiency. When the electric slider 10 drives the clamping arm 57 to move into the V-shaped groove 58, through the extrusion between the V-shaped groove 58 and the clamping arm 57, the reverse movement of the clamping arm 57 is realized, releasing the clamping and fixing of the clamping head 88. At this time, under the action of the fourth spring, the grinding wheel 82 automatically resets, and the cutting surface of the C-shaped steel of the photovoltaic bracket is ground again during the reset process.

[0036] It should be noted that for this PV bracket processing and cutting equipment, during use, first move the baffle 91 in the positioning and blocking mechanism 9 along the guiding slide rail 95 to adjust it to the specified position. At this time, start the second hydraulic cylinder 97. The output end of the second hydraulic cylinder 97 contracts, driving the baffle 91 to move downward, using the baffle 91 to block and limit the C-shaped steel of the PV bracket. At this time, use the material pushing mechanism 12 to push and load the C-shaped steel of the PV bracket. The first roller conveyor 1 and the second roller conveyor 7 are used to assist in loading the C-shaped steel of the PV bracket. The baffle 91 blocks and limits the C-shaped steel of the PV bracket. At this time, use the top pressing assembly 65 in the multi-point clamping mechanism 6 to press and fix multiple C-shaped steels of the PV bracket from top to bottom. With continuous pressing, drive the pressing block 656 and the pressing rod 658 thereon to move upward, synchronously compress the third spring 657, and at the same time drive the lifting plate 653 and the first rack 659 thereon to move upward, synchronously drive the first gear 651 and the fixed shaft 655 thereon to rotate, and at the same time drive the second gear 652 to rotate. The second gear 652 drives the second rack 661 and the connecting block 663 thereon to move centrally, synchronously drive the clamping arm 664 and the clamping block 665 thereon to move centrally, and use the clamping block 665 to clamp and fix the side of the C-shaped steel of the PV bracket, realizing the secondary clamping and fixing of the C-shaped steel of the PV bracket, achieving stable clamping of the C-shaped steel of the PV bracket. After clamping, use the laser cutting head 2 to sequentially perform laser cutting on multiple C-shaped steels of the PV bracket from back to front, synchronously drive the automatic locking and releasing mechanism 5 to move from back to front. After cutting, the output end of the second hydraulic cylinder 97 extends, synchronously driving the connecting plate 92 and the baffle 91 thereon to move upward, releasing the blocking and limiting of the C-shaped steel of the PV bracket. After cutting, lock and fix the clamping head 88 on the grinding mechanism 8 through the automatic locking and releasing mechanism 5. At this time, as the electric slider 10 moves backward, drive the automatic locking and releasing mechanism 5 and the clamping head 88 to move backward synchronously. Through extrusion, drive the two L-shaped rods 64 and the two fixing rods 67 thereon to move away from each other, and at the same time drive the first mounting plate 62 and the L-shaped fixing plate 63 thereon to move away from each other, synchronously realizing the top pressing assembly 65, the side clamping assembly 66 and the cut C-shaped steel of the PV bracket clamped thereon to move away from each other, realizing the automatic separation of the C-shaped steel of the PV bracket from the cutting surface. As the electric slider 10 continues to move backward, use the grinding wheel 82 to automatically grind the cutting surface, eliminating the need for subsequent manual grinding, realizing the integrated clamping, cutting and automatic grinding of multiple C-shaped steels of the PV bracket. After grinding, the grinding mechanism 8 resets. At this time, start the first roller conveyor 1 to move the C-shaped steel of the PV bracket cut to a fixed length and ground to the next step. After waiting for the cut C-shaped steel of the PV bracket to move out, the baffle 91 moves downward to block. Repeat the above steps, then realize the integrated positioning, clamping, cutting and grinding of multiple C-shaped steels of the PV bracket.
