Description

Technical Field

[0001] This invention belongs to the field of photovoltaic bracket manufacturing technology, specifically a processing device for photovoltaic bracket manufacturing. Background Technology

[0002] Photovoltaic brackets are the core supporting components of photovoltaic power generation systems. They need to be bent at specific angles using specialized processing equipment to adapt to different installation scenarios. The processing quality directly affects the stability and power generation efficiency of photovoltaic panels. During the production process, the bending process must take into account both structural strength and installation accuracy to ensure that the brackets can withstand external environmental forces such as wind loads and snow loads.

[0003] Patent CN222569871U discloses a bending device for photovoltaic bracket production, mainly composed of a support platform, a mounting platform, a mounting plate, and limiting components. A molding seat is set in the middle of the mounting plate to achieve tube bending. A connecting frame is installed on one side via a connecting groove, forming a grinding station. The bent tube can be directly moved into the mounting frame, where a high-speed grinding disc removes burrs from both sides of the bend, improving the product surface quality. The device is equipped with a collection box and a dust suction pipe interface. A negative pressure is generated by connecting an external dust collection device to effectively collect dust, debris, and pungent odors generated during grinding, improving the working environment. This design integrates bending, deburring, and dust removal processes, reducing the number of workpiece transfers, optimizing the production process, and combining processing efficiency with environmental safety. It is suitable for automated mass production of photovoltaic brackets.

[0004] In the above-mentioned scheme, before bending the workpiece, the operator needs to manually adjust two sets of limiting components to fix both ends of the workpiece. After the bending process is completed, the limiting components need to be manually released again, and the workpiece is transferred to the connecting frame for grinding. Throughout the process, the picking, placing and moving of the workpiece mainly depends on manual operation, and the degree of automation is low. At the same time, the frequent clamping and transfer actions consume a lot of time, making it difficult to achieve continuous processing and seriously restricting the improvement of overall processing efficiency. Therefore, the present invention provides a processing device for photovoltaic bracket production. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A processing device for photovoltaic bracket production, comprising a cabinet, a fixed column fixedly installed on the cabinet, a geared disc rotatably installed on the fixed column, the geared disc meshing with a gear, a drive shaft installed in the middle of the gear, the drive shaft rotatably installed on the cabinet, three sets of bending lower dies movably inserted into the geared disc at equal angles, two sets of support platforms symmetrically arranged on both sides of the bending lower dies, rollers rotatably installed at the lower end of the bending lower dies, a bending mechanism and a grinding mechanism arranged sequentially around the geared disc, fixed mechanisms installed on both sides of the bending mechanism and the grinding mechanism, the bending mechanism including a first fixed frame, the first fixed frame being fixedly installed on the machine... On the cabinet, a first cylinder is fixedly installed on the first fixed frame to drive the bending upper mold. The grinding mechanism includes a lifting mechanism, which is fixedly installed on the cabinet. A movable frame is installed on the lifting mechanism. Two sets of grinding discs are symmetrically rotated and installed on the movable frame. A dust suction pipe is fixedly installed on the grinding disc. An air pipe is connected to the end of the dust suction pipe. The fixing mechanism includes a second fixed frame, which is fixedly installed on the cabinet. A second cylinder is fixedly installed on the second fixed frame. A guide ring is provided below the gear plate. The guide ring is fixedly installed on the cabinet. A roller is rotatably connected to the upper end face of the guide ring. The upper end face of the guide ring is composed of a first arc-shaped surface, an inclined surface, and a second arc-shaped surface. By integrating the feeding point, bending process, and grinding process on the same rotating platform, the bending, grinding, and feeding processes can be carried out in parallel. Furthermore, the gear plate can rotate, enabling the feeding point, bending mechanism, and grinding mechanism to cycle and work together, eliminating waiting time between processes. This not only improves the automation rate of the device but also increases the grinding efficiency of the workpiece.

[0007] Preferably, the bending die includes a fixed base, which is movably inserted into the gear plate; a movable plate movably inserted into the fixed base; two sets of trapezoidal blocks symmetrically mounted on the movable plate; a slider fixedly connected to the end of the movable plate; a slide rail slidably connected to the slider; a receiving seat fixedly connected to the slide rail; and a support rod fixedly mounted on the receiving seat. The fixed base has a movable groove, and the two sets of trapezoidal blocks are symmetrically mounted within the movable groove. Two sets of through holes are provided on both sides of the movable groove. A guide post is provided at one end of each trapezoidal block, and the guide post is slidably connected to the through hole. Two sets of first inclined grooves are symmetrically provided on the movable plate. A convex shaft is provided at the bottom of each set of trapezoidal blocks, and the convex shaft is located within the first inclined groove. A pin is provided at one end of the support rod, and a fixed post is fixed to the support rod. The set includes a guide plate with a guide groove. The pin is located in the guide groove, which includes a first arc-shaped groove, a second inclined groove, and a second arc-shaped groove. Sliding sleeves are provided on both sides of the receiving seat, and the sliding sleeves are slidably connected to sliding rods, which are fixedly installed on the gear plate. Guided by the first inclined groove, the two sets of trapezoidal blocks move in opposite directions, thereby increasing the distance between the two sets of trapezoidal blocks until the pin slides from the second inclined groove into the second arc-shaped groove. At this time, the roller rolls from the second arc-shaped surface to the first arc-shaped surface. As the distance between the two sets of trapezoidal blocks increases, the pressure of the two sets of trapezoidal blocks on the bending section is relieved. Under the action of gravity, the bending section of the workpiece can smoothly detach from the mold cavity of the lower bending mold, avoiding the impact on the grinding of the bending section.

[0008] Preferably, the bending die further includes a support mechanism, which includes a movable block, a guide groove on the fixed base, the movable block being slidably connected to the guide groove, two sets of guide rails symmetrically arranged on both sides of the movable block, two sets of limiting blocks symmetrically arranged on both sides of one end of the movable block, a magnetic sheet fixedly installed on the limiting block, a sliding groove on both sides of the guide groove, the guide rail being slidably connected to the sliding groove, a receiving groove on the bottom of the movable block, a driving block on one end of the movable plate, the driving block being slidably connected to the receiving groove, a magnetic block being embedded in one end of the driving block, and two sets of straight grooves symmetrically arranged on the movable plate, the two sets of straight grooves being respectively connected to two sets of first inclined grooves, the guide groove also including a third inclined groove, a third arc groove, and a fourth inclined groove.

[0009] The drive block is attracted to the bottom of the receiving groove by the magnetic block and pushes the bottom of the receiving groove, so that the movable block moves between the two sets of trapezoidal blocks until the pin slides from the third inclined groove into the third arc groove and slides along the third arc groove, thereby keeping the movable block between the two sets of trapezoidal blocks. The movable block also supports the bending section of the workpiece, thereby reducing the deformation of the workpiece caused by grinding and improving product quality.

[0010] The beneficial effects of this invention are as follows: 1. The feeding point, bending process, and grinding process are integrated on the same rotating platform to achieve parallel operation of bending, grinding, and feeding. The gear plate can rotate to make the feeding point, bending mechanism, and grinding mechanism work together in a cycle, eliminating the waiting time between processes. This not only improves the automation rate of the device, but also improves the grinding efficiency of the workpiece.

[0011] 2. When the roller rolls from the second arc surface to the first arc surface, the workpiece bending section will detach from the lower bending die. At this time, the pin slides along the second arc groove, and one end of the drive block is attached to the bottom of the receiving groove. When the pin slides from the second arc groove into the third inclined groove, the pin will drive the support rod and the receiving seat to continue moving towards the center of the gear plate. At this time, the movable plate will continue to move with the receiving seat, and the convex shaft at the bottom of the trapezoidal block will slide along the first inclined groove into the straight groove. At the same time, the movable plate drives the drive block to move. The drive block is attracted to the bottom of the receiving groove by the magnetic block and pushes the bottom of the receiving groove, so that the movable block moves between the two sets of trapezoidal blocks until the pin slides from the third inclined groove into the third arc groove and slides along the third arc groove, thereby keeping the movable block between the two sets of trapezoidal blocks. The movable block also supports the bending section of the workpiece, thereby reducing the deformation of the workpiece caused by grinding and improving product quality. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Example 1: As Figures 1 to 3As shown in the embodiment of the present invention, a processing device for photovoltaic bracket production includes a cabinet 1. A fixed column 2 is fixedly installed on the cabinet 1. A gear 3 is rotatably installed on the fixed column 2. The gear 3 meshes with a gear 4. A drive shaft 5 is installed in the middle of the gear 4. The drive shaft 5 is rotatably installed on the cabinet 1. Three sets of lower bending dies 6 are movably inserted into the gear 3 at equal angles. Two sets of support platforms 8 are symmetrically arranged on both sides of the lower bending dies 6. Rollers 7 are rotatably installed at the lower end of the lower bending dies 6. A bending mechanism 9 and a grinding mechanism 10 are arranged in sequence around the gear 3. Fixing mechanisms 11 are installed on both sides of the bending mechanism 9 and the grinding mechanism 10. The bending mechanism 9 includes a first fixing frame 901, which is fixedly installed on the cabinet 1. The first fixing frame 901 is used to drive the upper bending die 90. The first cylinder 902 of the 3, the grinding mechanism 10 includes a lifting mechanism 101, the lifting mechanism 101 is fixedly installed on the cabinet 1, a movable frame 102 is installed on the lifting mechanism 101, two sets of grinding discs 103 are symmetrically rotated and installed on the movable frame 102, a dust suction pipe 104 is fixedly installed on the grinding disc 103, and an air pipe 105 is connected to the end of the dust suction pipe 104. The fixing mechanism 11 includes a second fixing frame 111, the second fixing frame 111 is fixedly installed on the cabinet 1, a second cylinder 112 is fixedly installed on the second fixing frame 111, a guide ring 12 is provided below the gear plate 3, the guide ring 12 is fixedly installed on the cabinet 1, and a roller 7 is rotatably connected to the upper end face of the guide ring 12. The upper end face of the guide ring 12 is composed of a first arc surface 121, an inclined surface 122, and a second arc surface 123.

[0025] Specifically, attached Figure 1The middle arrow indicates the loading point. In the initial state, a set of lower bending dies 6 and two sets of support platforms 8 are located at this loading point. The air pipe 105 is connected to a vacuum cleaner. When it is necessary to bend the tubular workpiece of the photovoltaic bracket, the workpiece is placed on the two sets of support platforms 8 located at the loading point. At this time, the upper end face of the lower bending die 6 at the loading point is lower than the lower end face of the workpiece. Then, the drive shaft 5 is driven to rotate by the motor. The drive shaft 5 drives the gear 4 to rotate. The gear 4 drives the gear disk 3, together with the lower bending die 6 and the support platforms 8, to rotate towards the bending mechanism 9. During the rotation, the roller 7 at the lower end of the lower bending die 6 rolls along the first arc surface 121. Then, the roller 7 rolls along the first arc surface 121. The inclined surface 122 rolls onto the second arc surface 123. The roller 7 is pushed by the inclined surface 122, causing the entire lower bending die 6 to move upward until the upper end face of the lower bending die 6 is in contact with the lower end face of the workpiece. Then, the rotation of the gear 3 is paused, and the fixing mechanisms 11 on both sides of the bending mechanism 9 are activated. The end of the second cylinder 112 presses down on the end of the workpiece, fixing the end of the workpiece on the support table 8. Then, the first cylinder 902 pushes the upper bending die 903 to press down on the middle of the workpiece. The bending of the middle of the workpiece is achieved through the cooperation of the upper bending die 903 and the lower bending die 6. During the bending process, the next set of workpieces is placed on the two sets of loading points. On the support platform 8, after bending is completed, the upper bending die 903 and the two sets of second cylinders 112 are retracted, and the gear disc 3 continues to rotate, causing the bent workpiece to rotate below the grinding mechanism 10. During this process, the roller 7 rolls from the second arc surface 123 to the first arc surface 121. Under the action of gravity, the entire lower bending die 6 moves downward, causing the middle bending section of the workpiece to detach from the lower bending die 6. Then, the two sets of grinding discs 103 are driven to rotate by two sets of motors. At the same time, the lifting mechanism 101 drives the two sets of grinding discs 103 to move downward through the movable frame 102. During the downward movement, the rotating grinding discs 103 grind both sides of the middle bending section of the workpiece. During this process, the vacuum cleaner generates suction through the suction pipe 104 to remove the metal dust produced during grinding. While the grinding disc 103 is grinding the workpiece, the operator simultaneously places the workpiece at the loading point, and the bending mechanism 9 continues to bend the workpiece. This process is repeated cyclically. Compared with existing technologies, this method integrates the loading point, bending process, and grinding process on the same rotating platform, enabling parallel operation of bending, grinding, and loading. Furthermore, the toothed disc 3 can rotate, allowing the loading point, bending mechanism 9, and grinding mechanism 10 to work in a cyclical manner, eliminating waiting time between processes. This not only improves the automation rate of the device but also increases the grinding efficiency of the workpiece.

[0026] like Figures 4 to 6As shown, the bending die 6 includes a fixed base 601, which is movably inserted into the gear plate 3; a movable plate 602 movably inserted into the fixed base 601; two sets of trapezoidal blocks 603 symmetrically movably installed on the movable plate 602; a slider 604 fixedly connected to the end of the movable plate 602; a slide rail 610 slidably connected to the slider 604; a receiving seat 605 fixedly connected to the slide rail 610; and a support rod 606 fixedly installed on the receiving seat 605. The fixed base 601 has a movable groove 6011, and the two sets of trapezoidal blocks 603 are symmetrically installed within the movable groove 6011. Two sets of through holes 6012 are provided on both sides of the movable groove 6011. A guide post 6031 is provided at one end of each trapezoidal block 603. The sliding connection of the 6031 through hole 6012 is provided. Two sets of first inclined grooves 6021 are symmetrically opened on the movable plate 602. The bottom of the two sets of trapezoidal blocks 603 are provided with convex shafts 6032, which are located in the first inclined grooves 6021. One end of the support rod 606 is provided with a pin 6061. A guide plate 201 is fixedly fitted on the fixed column 2. A guide groove 202 is opened on the guide plate 201. The pin 6061 is located in the guide groove 202. The guide groove 202 includes a first arc groove 2021, a second inclined groove 2022, and a second arc groove 2023. Sliding sleeves 607 are provided on both sides of the receiving seat 605. The sliding sleeves 607 are slidably connected to the sliding rod 608. The sliding rod 608 is fixedly installed on the gear plate 3.

[0027] Specifically, during the bending process, the middle part of the workpiece is pressed into the cavity of the lower bending die 6 by the upper bending die 903 to achieve bending. Due to the elasticity and stress of the metal, the bending section in the middle of the workpiece will get stuck in the cavity of the lower bending die 6. Under its own gravity, the bending section cannot get out of the cavity of the lower bending die 6, thus affecting the subsequent grinding of the bending section. After the workpiece is bent, the bent section will be stuck between the two sets of trapezoidal blocks 603. The roller 7 at the lower end of the bending die 6 will first roll along the second arc surface 123. During the rolling process, the pin 6061 on the bending die 6 will slide from the first arc groove 2021 into the second inclined groove 2022. Guided by the second inclined groove 2022, the pin 6061 will drive the support rod 606 and the receiving seat 605 to move towards the center of the gear plate 3. The receiving seat 605 will also drive the sliding sleeve 607 to slide along the sliding rod 608, which will guide the movement of the receiving seat 605. At the same time, the receiving seat 605 will drive the slider 604 and the movable plate 602 to move together through the slide rail 610. As the movable plate 602 moves, the convex shaft 6032 at the bottom of the trapezoidal block 603 slides along the first inclined groove 6021. Guided by the first inclined groove 6021, the two sets of trapezoidal blocks 603 move in opposite directions, thereby increasing the distance between the two sets of trapezoidal blocks 603 until the pin 6061 slides from the second inclined groove 2022 into the second arc groove 2023. At this time, the roller 7 rolls from the second arc surface 123 onto the first arc surface 121. As the distance between the two sets of trapezoidal blocks 603 increases, the pressure of the two sets of trapezoidal blocks 603 on the bending section is relieved. Under the action of gravity, the bending section of the workpiece can smoothly leave the mold cavity of the lower bending mold 6, avoiding the impact on the grinding of the bending section.

[0028] Example 2: Figures 7 to 9 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the bending lower mold 6 further includes a support mechanism 609, the support mechanism 609 includes a movable block 6091, a guide groove 6013 is provided on the fixed base 601, the movable block 6091 is slidably connected to the guide groove 6013, two sets of guide rails 6092 are symmetrically arranged on both sides of the movable block 6091, two sets of limiting blocks 6093 are symmetrically arranged on both sides of one end of the movable block 6091, and magnetic sheets 6094 are fixedly installed on the limiting blocks 6093. The guide groove 6013 has a guide rail 6092 on both sides. The slide 6014 and guide rail 6092 are slidably connected to the slide 6014. The bottom of the movable block 6091 is provided with a receiving groove 91. A driving block 6023 is provided on one end of the movable plate 602. The driving block 6023 is slidably connected to the receiving groove 91. A magnetic block 6024 is embedded in one end of the driving block 6023. The movable plate 602 is also symmetrically provided with two sets of straight grooves 6022. The two sets of straight grooves 6022 are respectively connected to two sets of first inclined grooves 6021. The guide groove 202 also includes a third inclined groove 2024, a third arc groove 205, and a fourth inclined groove 206.

[0029] Specifically, when the workpiece bending section is removed from the lower bending die 6, the workpiece bending section is in a suspended state. When the grinding disc 103 grinds both sides of the workpiece bending section, the grinding disc 103 will apply downward pressure and vibration to the workpiece bending section. Since the workpiece bending section is not supported, it is easy for the entire workpiece to be completely deformed, reducing the workpiece quality. In the initial state, the magnetic sheet 6094 is adsorbed on the inner wall of the guide groove 6013 to achieve the pre-positioning of the movable block 6091, and one end of the drive block 6023 is not attached to the bottom of the receiving groove 91. When the roller 7 rolls from the second arc surface 123 to the first arc surface 121, the workpiece bending section will detach from the bending die 6. At this time, the pin 6061 slides along the second arc groove 2023, and one end of the drive block 6023 is attached to the bottom of the receiving groove 91. When the pin 6061 slides from the second arc groove 2023 into the third inclined groove 2024, the pin 6061 will drive the support rod 606 together with the receiving seat 605 to continue moving towards the center of the gear plate 3. At this time, the movable plate 602 will continue to move with the receiving seat 605, and the convex shaft 6032 at the bottom of the trapezoidal block 603 will move along the first inclined groove 6021. 21 slides into the straight groove 6022, while the movable plate 602 drives the drive block 6023 to move. The drive block 6023 is attracted to the bottom of the receiving groove 91 by the magnetic block 6024 and pushes the bottom of the receiving groove 91, so that the movable block 6091 moves between the two sets of trapezoidal blocks 603 until the pin 6061 slides from the third inclined groove 2024 into the third arc groove 205 and slides along the third arc groove 205, thereby keeping the movable block 6091 between the two sets of trapezoidal blocks 603. The movable block 6091 also supports the bending section of the workpiece, thereby reducing the deformation of the workpiece caused by grinding and improving product quality.

[0030] Working principle: The workpiece is placed on two sets of support platforms 8 located at the loading point. At this time, the upper end face of the lower bending die 6 at the loading point is lower than the lower end face of the workpiece. Then, the drive shaft 5 is driven by the motor to rotate, and the drive shaft 5 drives the gear 4 to rotate. The gear 4 drives the gear disk 3, along with the lower bending die 6 and the support platforms 8, to rotate together in the direction of the bending mechanism 9. During the rotation, the roller 7 at the lower end of the lower bending die 6 rolls along the first arc surface 121, and then rolls from the inclined surface 122 to the second arc surface 123. 7. Pushed by the inclined surface 122, the entire lower bending die 6 moves upward until the upper end face of the lower bending die 6 is in contact with the lower end face of the workpiece. Then, the rotation of the gear disk 3 is paused, and the fixing mechanisms 11 on both sides of the bending mechanism 9 are activated. The end of the second cylinder 112 presses down on the end of the workpiece, fixing the end of the workpiece to the support table 8. Then, the first cylinder 902 pushes the upper bending die 903 to press down on the middle of the workpiece. The bending of the middle of the workpiece is achieved through the cooperation of the upper bending die 903 and the lower bending die 6. During the bending process, the next set of workpieces is placed on the two sets of support platforms 8 at the loading point. After bending is completed, the upper bending die 903 and the two sets of second cylinders 112 are retracted, and the gear plate 3 continues to rotate, causing the bent workpiece to rotate below the grinding mechanism 10. During this process, the roller 7 rolls from the second arc surface 123 to the first arc surface 121. Under the action of gravity, the entire lower bending die 6 moves downward, causing the middle bending section of the workpiece to detach from the lower bending die 6. Then, the two sets of motors drive the two sets of support platforms 8 to rotate. The grinding disc 103 rotates, and at the same time the lifting mechanism 101 drives the two sets of grinding discs 103 to move downward through the movable frame 102. During the downward movement, the rotating grinding disc 103 grinds both sides of the bending section in the middle of the workpiece. During this process, the vacuum cleaner generates suction through the suction pipe 104 to remove the metal dust generated by grinding. While the grinding disc 103 is grinding the workpiece, the worker places the workpiece at the loading point, and the bending mechanism 9 continues to bend the workpiece. The above operation is repeated in a cycle. After the workpiece is bent, the bent section will be stuck between the two sets of trapezoidal blocks 603. The roller 7 at the lower end of the bending die 6 will first roll along the second arc surface 123. During the rolling process, the pin 6061 on the bending die 6 will slide from the first arc groove 2021 into the second inclined groove 2022. Guided by the second inclined groove 2022, the pin 6061 will drive the support rod 606 and the receiving seat 605 to move towards the center of the gear plate 3. The receiving seat 605 will also drive the sliding sleeve 607 to slide along the sliding rod 608, which will guide the movement of the receiving seat 605. At the same time, the receiving seat 605 will drive the slider 604 and the movable plate through the slide rail 610. As the movable plate 602 moves, the convex shaft 6032 at the bottom of the trapezoidal block 603 slides along the first inclined groove 6021. Guided by the first inclined groove 6021, the two sets of trapezoidal blocks 603 move in opposite directions, thereby increasing the distance between the two sets of trapezoidal blocks 603 until the pin 6061 slides from the second inclined groove 2022 into the second arc groove 2023. At this time, the roller 7 rolls from the second arc surface 123 onto the first arc surface 121. As the distance between the two sets of trapezoidal blocks 603 increases, the pressure of the two sets of trapezoidal blocks 603 on the bending section is relieved. Under the action of gravity, the bending section of the workpiece can smoothly leave the mold cavity of the lower bending mold 6. When roller 7 rolls from the second arc surface 123 to the first arc surface 121, the workpiece bending section will detach from the bending die 6. At this time, pin 6061 slides along the second arc groove 2023, and one end of drive block 6023 is attached to the bottom of receiving groove 91. When pin 6061 slides from the second arc groove 2023 into the third inclined groove 2024, pin 6061 will drive support rod 606 together with receiving seat 605 to continue moving towards the center of gear plate 3. At this time, movable plate 602 will continue to move with receiving seat 605, and the convex shaft 6032 at the bottom of trapezoidal block 603 will continue to move. The movable block 6091 will slide into the straight groove 6022 along the first inclined groove 6021. At the same time, the movable plate 602 drives the driving block 6023 to move. The driving block 6023 is attracted to the bottom of the receiving groove 91 by the magnetic block 6024 and pushes the bottom of the receiving groove 91, so that the movable block 6091 moves between the two sets of trapezoidal blocks 603 until the pin 6061 slides into the third arc groove 205 from the third inclined groove 2024 and slides along the third arc groove 205, thereby keeping the movable block 6091 between the two sets of trapezoidal blocks 603. The movable block 6091 also supports the bending section of the workpiece.
