Description

Technical Field

[0001] This invention relates to the field of aluminum alloy frame processing equipment, specifically to an automatic cutting device for photovoltaic aluminum alloy frame blanking. Background Technology

[0002] Photovoltaic aluminum alloy frames are important structural components of solar photovoltaic modules. They are made of high-strength, corrosion-resistant aluminum alloy through extrusion molding and mainly serve to fix, support, and protect photovoltaic panels. With their lightweight, high strength, good thermal conductivity, and recyclability, photovoltaic aluminum alloy frames are widely used in various ground-mounted power stations and distributed photovoltaic systems. They are key structural components that ensure the long-term stable operation of photovoltaic modules and extend their service life.

[0003] The automatic cutting machine for photovoltaic aluminum alloy frames is a key piece of equipment in photovoltaic module production. It is designed for the precise cutting of raw materials for aluminum alloy frames. The equipment uses advanced automation technology and is often equipped with an automated feeding system, which can orderly feed aluminum alloy profiles into the cutting area, saving manpower and improving efficiency. The cutting power comes from a high-power motor, which is equipped with a high-quality saw blade to efficiently cut aluminum alloy materials. The cutting accuracy can usually reach ±0.1mm, meeting high production standards.

[0004] In the field of automated processing of photovoltaic aluminum alloy frames, the process fragmentation problem of existing single-function blanking and cutting equipment has become a core bottleneck restricting the efficiency of large-scale production of photovoltaic modules. Conventional gantry aluminum alloy cutting machines or circular saws only have straight cutting functions, while the processing technology of photovoltaic frames not only requires precise cutting, but also requires the processing of assembly features such as tenon holes and bolt holes at both ends of the frame. After processing with conventional cutting equipment, the cut frame needs to be transferred to a special CNC drilling machine, re-clamped and positioned, and then drilled. The processing time for a single hole is 3-5 seconds. If 2-4 holes are required at each end of the frame, the drilling time for a single frame can reach 12-20 seconds.

[0005] This process splitting leads to significant time loss. For example, the turnaround time between processes for a single frame (including transmission, positioning, and secondary clamping) can reach 15-30 seconds, which is 2-5 times more auxiliary time than integrated processing. In a production line with an annual output of 1 million photovoltaic modules, this loss can lead to an extension of the annual processing cycle by 2,000-3,000 hours, directly affecting the release of production capacity. To address this, we propose an automatic cutting device for photovoltaic aluminum alloy frames. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an automatic cutting device for photovoltaic aluminum alloy frames. This solves the problem that existing automatic cutting devices require transferring the cut frames to a dedicated CNC drilling machine for re-clamping and positioning before drilling. Each hole takes 3-5 seconds to process, and if 2-4 holes are needed at each end of the frame, drilling a single frame takes 12-20 seconds, resulting in significant time loss and directly affecting production capacity.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In this invention, a multi-functional processing system for "synchronous drilling-automatic reset" at the workpiece cutting end is constructed by setting up a drilling device consisting of a motor, gear one, gear two, synchronous pulley one, synchronous pulley two, and a guide frame, and an auxiliary device consisting of an air compressor, air guide pipe, sleeve, pressing block, piston, and spring. When the protective cover is in place, the motor drives the guide frame to precisely position the drill bit through gear and synchronous pulley transmission. At the same time, the compressed air output by the air compressor pushes the pressing block through the sleeve, so that the drill bit can achieve controllable feed under the dual action of air pressure and spring, and simultaneously complete the processing of assembly features such as threaded bottom holes and positioning countersunk holes at the workpiece cutting end. By setting up the drilling device and the auxiliary device, the equipment can open assembly features on the surface of the workpiece cutting end during the cutting operation, and directly complete the hole processing at the cutting station, eliminating the positioning deviation caused by secondary clamping from the source, improving the automation level and overall efficiency of workpiece production, reducing the subsequent processing steps of the workpiece, and improving the production efficiency of the workpiece.

[0025] 2. In this invention, an automatic cleaning system of "air-brush linkage" during drill bit reset is constructed by setting up an auxiliary device consisting of an air compressor, a guide pipe, an assembly head, an air chamber, an air blowing hole, a guide frame, and brush bristles: When the drill bit resets and passes through the guide frame, the air compressor delivers high-pressure gas to the assembly head through the guide pipe, and the air chamber forms a high-speed airflow through the air blowing hole to sweep the surface of the drill bit, simultaneously cooperating with the mechanical wiping action of the brush bristles to achieve dual cleaning of "airflow stripping + brush bristle scraping"; the angle design of the air blowing hole is precisely matched with the movement trajectory of the drill bit to ensure that the high-pressure airflow penetrates deep along the spiral channel to flush away attached metal debris, The coolant residue and other impurities are thoroughly removed. The elastic bristles are made of wear-resistant nylon and maintain constant pressure on the drill bit surface under the guidance of the guide frame. This effectively scrapes away stubborn impurities without damaging the drill bit coating. When the drill bit resets, its surface can be cleaned, reducing the fluctuation of cutting resistance and wear rate during subsequent machining. Especially in precision drilling scenarios, this design effectively avoids positioning deviations caused by residual debris and reduces problems such as drill bit chipping and workpiece scrap caused by impurities. It ensures the stability of machining quality from the source and provides reliable support for the continuous and efficient operation of the drill bit. Attached Figure Description

[0045] The upper surface of the body 1 is also provided with an auxiliary device 7 for assisting the opening device 6. The auxiliary device 7 is composed of an air compressor 71, an air guide pipe 72, a connector 73, a sleeve 74, a pressing block 76, a piston 77 and other structures.

[0046] The inner walls of both the first synchronous pulley 611 and the second synchronous pulley 613 are fixedly connected with protrusions 614. The surface of the guide frame 65 is provided with grooves that fit the protrusions 614. The protrusions 614 are slidably connected to the inner wall of the grooves. By utilizing the cooperation between the protrusions 614 and the grooves, the guide frame 65 can be driven to rotate while the synchronous pulleys are rotating, so that the drill bit 64 installed on the guide frame 65 can follow and enter the rotation state.

[0047] The fixed plate 66 has a circular hole on its surface, the guide frame 65 is located on the inner wall of the circular hole, and the cover 67 is fitted on the surface of the guide frame 65. The cover 67 can be used to shield and protect the meshing parts of gear 1 69 and gear 2 610, so as to increase the stability and safety of gear 1 69 and gear 2 610 in the transmission state.

[0049] The auxiliary device 7 includes an air compressor 71, which is fixedly connected to the upper surface of the body 1. An air guide pipe 72 is fixedly connected to the first output port of the air compressor 71. A connector 73 is threadedly connected to the output end of the air guide pipe 72. A sleeve 74 is fixedly connected to the surface of the connector 73. The sleeve 74 is fixedly connected to the upper surface of the cover 67 and is sleeved on the surface of the guide frame 65.

[0050] The upper surface of the guide frame 65 is provided with a threaded groove 75. A pressing block 76 is threadedly connected to the inner wall of the guide frame 65 in the threaded groove 75. A piston 77 is fixedly connected to the surface of the pressing block 76. The piston 77 movably abuts against the upper surface of the guide frame 65. A limit frame 78 is slidably connected to the inner wall of the guide frame 65. A spring 79 is fixedly connected to the upper surface of the limit frame 78. The end of the spring 79 away from the limit frame 78 is fixedly connected to the inner wall of the guide frame 65.

[0051] The pressing block 76 is located inside the sleeve 74, and the piston 77 is in contact with the inner wall of the sleeve 74. By using the cooperation between the piston 77 and the sleeve 74, the upper end of the guide frame 65 can be sealed to ensure that after the air enters the sleeve 74, the guide frame 65 can be moved by the gas pressure.

[0052] The sleeve 74 has a rotating groove inside, and the limiting frame 78 is rotatably connected to the inside of the rotating groove. The limiting frame 78 can support the position of the spring 79 and limit one end of the spring 79, so that the spring 79 can push the guide frame 65 to reset after being released.

[0053] The guide rail 61 is provided with an auxiliary device 8, which includes a fixing frame 81. The fixing frame 81 is installed on the surface of the guide rail 61, and an assembly frame 82 is fixedly connected to the surface of the fixing frame 81. Bolts 83 are inserted into the inner wall of the assembly frame 82 and are threadedly connected to the inner wall of the guide rail 61. A guide frame 84 is fixedly connected to the surface of the assembly frame 82 and is sleeved on the surface of the drill bit 64.

The input end of the guide tube 86 is fixedly connected to the second output port of the air compressor 71. An air chamber 87 is opened in the inner wall of the guide frame 84, and an air blowing hole 88 is opened in the inner wall of the air chamber 87. By using the cooperation of the fixing frame 81 and the bolts 83, the assembly frame 82 can be fixed on the guide rail 61 to ensure the stability and firmness of the assembly frame 82.

[0054] The inner wall of the guide frame 84 is fixedly connected with bristles 89, which are in contact with the surface of the drill bit 64. By using the bristles 89 inside the guide frame 84, the drill bit 64 can be cleaned of impurities attached to the surface of the drill bit 64 by using the air blowing hole 88 in the ventilation state when the drill bit 64 is reset.

[0055] The assembly head 85 is connected to the interior of the air chamber 87, and the air blowing hole 88 is connected to the inner wall of the guide frame 84. By using the cooperation between the assembly head 85 and the air chamber 87, the gas delivered by the guide tube 86 can be injected into the air blowing hole 88, so that the air blowing hole 88 can blow gas outward to achieve the cleaning function of the air blowing hole 88.

[0056] The working principle of this invention is as follows: During processing, the workpiece to be processed is placed in the loading area, and then the loading mechanism 5 is controlled to work. The loading mechanism 5 is powered on and pushes the workpiece to the cutting area of ​​the machine body 1. After loading is completed, the hydraulic cylinder 3 is controlled to work and push the protective cover 4 to move downward and block the cutting area. When the protective cover 4 completely blocks the cutting area, the protective cover 4, together with the hydraulic cylinder 3, presses and clamps the workpiece in the cutting area. Then, the machine body 1 works and pushes the cutting mechanism 2 in the working state upward. During the movement, the cutting mechanism 2 will cut the workpiece.

[0057] When the protective cover 4 moves into place, the motor 68 is controlled to work and, together with gear 1 69 and gear 2 610, drives synchronous pulley 1 611. Synchronous pulley 1 611 drives synchronous pulley 2 613 under the action of synchronous belt 612. Synchronous pulley 2 613 rotates with synchronous pulley 1 611. At this time, synchronous pulley 1 611 and synchronous pulley 2 613 rotate the corresponding guide frame 65 respectively. The guide frame 65 synchronously drives the drill bit 64. The drill bit 64 enters the working state under the action of the guide frame 65.

[0058] While the motor 68 is working, the air compressor 71 works in conjunction with the air guide pipe 72 and the connector 73 to pump the compressed air into the sleeve 74. After entering the sleeve 74, the air is restricted by the sleeve 74 and pushes the pressing block 76 and the piston 77 downward. Under the guidance of the sleeve 74, the pressing block 76 and the piston 77 push the guide frame 65 in the specified direction. During the movement, the guide frame 65 compresses the spring 79, which is deformed. Under the guidance of the protrusion 614 and the groove, the guide frame 65 pushes the drill bit 64 in the specified direction. The drill bit 64 moves downward and drills holes in the workpiece in the processing area.

[0059] After the cutting is completed and the protective cover 4 is driven to reset, the air compressor 71 disconnects from the air pipe 72. At this time, the air pipe 72 is connected to the outside through the solenoid valve on the first output port of the air compressor 71. When the air pipe 72 is connected to the outside, the compressed air in the air pipe 72 is discharged. At this time, the pressing block 76 and the piston 77 lose the pressure applied by the air and stop pushing the guide frame 65. The guide frame 65 stops applying pressure to the spring 79. The spring 79 loses pressure and rebounds, pushing the guide frame 65 to reset. During the reset process, the guide frame 65 pulls the drill bit 64 to reset. By setting the hole opening device 6 and the assisting device 7, the equipment can open the assembly features on the surface of the workpiece cutting end when performing the cutting operation, and directly complete the hole processing at the cutting station. This eliminates the positioning deviation caused by secondary clamping from the source, improves the automation level and overall efficiency of workpiece production, reduces the subsequent processing of the workpiece, and improves the production efficiency of the workpiece.

[0060] In addition, when the drill bit 64 is reset, the second output port of the air compressor 71 is opened. The air compressor 71, together with the guide pipe 86, pumps air to the assembly head 85. The assembly head 85 introduces air into the air chamber 87. After the air is injected into the air chamber 87, the high-pressure gas is sent out through the air blowing hole 88. During the blowing process of the air blowing hole 88, the drill bit 64 gradually passes through the guide frame 84. At this time, the air blowing hole 88 uses air in conjunction with the brush bristles 89 to clean the impurities attached to the surface of the drill bit 64. By setting the auxiliary device 8, the surface of the drill bit 64 can be cleaned when the drill bit 64 is reset, which can reduce the fluctuation of cutting resistance and wear rate during subsequent processing. Especially in precision drilling scenarios, this design can effectively avoid positioning deviation caused by residual chips, reduce problems such as drill bit 64 chipping and workpiece scrap caused by impurities, ensure the stability of processing quality from the source, and provide reliable support for the continuous and efficient operation of the drill bit 64.
