Description

Technical Field

[0001] This invention relates to the field of photovoltaic bracket manufacturing technology, specifically to an integrated equipment for punching and cutting photovoltaic brackets. Background Technology

[0002] With the development of industrialization, the use of various photovoltaic brackets is increasing. In the process of photovoltaic bracket processing, it is often necessary to cut or punch the photovoltaic brackets, so cutting and punching equipment is required.

[0003] For example, Chinese patent publication number "CN120644995A" discloses "An Integrated Punching and Cutting Equipment for Photovoltaic Brackets." Its main structure includes a base for stable support during the punching and cutting of photovoltaic brackets. Guide rails are fixedly installed on the side of the top of the base. This integrated punching and cutting equipment for photovoltaic brackets, after the operator positions the photovoltaic bracket profile, starts a first hydraulic press to drive a stamping plate to slide on a telescopic frame, allowing the punched part to descend inside the telescopic frame to punch the photovoltaic bracket profile extending below it. The operator then starts the first hydraulic press, causing the hydraulic press drive end to move the positioning block and connecting block along with the stamping plate on the telescopic frame. At this time, multiple punching rods punch holes in the photovoltaic bracket profile. These multiple punching rods are correspondingly set with positioning slots to facilitate simultaneous processing of multiple sets of photovoltaic bracket profiles, thereby increasing punching efficiency, reducing errors caused by multiple positioning steps, and improving product quality.

[0004] However, in the aforementioned integrated photovoltaic bracket punching and cutting equipment, the mechanisms used for bracket punching and cutting come from two independent drive sources. Due to the increase in drive equipment, the maintenance cost, manufacturing cost and usage cost of the entire equipment will undoubtedly increase. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 and Figure 2 A photovoltaic bracket punching and cutting integrated equipment includes a processing table 1 with legs installed at the bottom, a cutting opening 2 set in the middle of the processing table 1, and a drive motor 4 fixedly installed on one side of the processing table 1 through a motor fixing base 3. When the drive motor 4 is started, the rotation of the drive motor 4 serves as a power source to perform cutting and punching functions on the photovoltaic bracket.

[0021] To achieve both punching and cutting functions using the same power source, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4A driven processing mechanism 5 needs to be set up. Its structure includes a cutting wheel 54 located directly above the cutting opening 2 and capable of rotation, a crankshaft 52 that enables the cutting wheel 54 to rotate with the rotor of the drive motor 4, a movable connecting rod 56 that converts the circular motion of the crankshaft 52 into reciprocating telescopic motion, a driven block 59 that generates telescopic motion with one end of the movable connecting rod 56, and a punch 510 that generates a punching effect on the component. The rotor of the drive motor 4 will drive the crankshaft 52 to rotate rapidly, and the crankshaft 52 will directly drive the cutting wheel 54 to rotate, thereby performing the cutting function on the photovoltaic bracket. The rotating crankshaft 52 will cause the movable connecting rod 56 to drive the driven block 59 to generate a reciprocating telescopic phenomenon. During the directional movement of the driven block 59, the punch 510 located at its tail will continuously adapt to the punch 514, thereby performing the punching function on the photovoltaic bracket, thus realizing both punching and cutting functions.

[0022] For details regarding the specific structure of the driven machining mechanism 5, please refer to [link / reference]. Figure 3 and Figure 4 It also includes a shaft mounting base 51 and a limiting cylinder 516 mounted on two horizontal shafts of the crankshaft 52 via bearings. The shaft mounting base 51 is fixedly mounted on the upper surface of the processing table 1. A first docking plate 53 is mounted on each end of the crankshaft 52, and one of the first docking plates 53 is fixedly connected to the cutting wheel 54. A movable connecting rod 56 is mounted on the shaft of the crankshaft 52 via a bushing 55. A rotating ball head 57 is fixedly mounted on one end of the movable connecting rod 56. The limiting cylinder 516 is fixedly mounted on the upper surface of a bottom fixing plate 512 via a cylinder fixing base 511. A limiting base 513 is fixedly mounted on the upper surface of the bottom fixing plate 512. A punch 514 with open ends is provided at the center of the limiting base 513. The limiting cylinder 516 has an inner movable cavity 515 with open ends inside. Inside the inner movable cavity 515, the cylindrical body 516 houses a driven block 59 capable of moving axially along the inner movable cavity 515. One end of the driven block 59 is provided with a spherical mounting groove 58 for accommodating a rotating ball head 57. Another end of the driven block 59 is provided with a punch rod 510 integrally formed with it and adapted to the punch hole 514.

The structural radius of the rotating ball head 57 is adapted to the structural radius of the spherical mounting groove 58, and the depth of the spherical mounting groove 58 is greater than the structural radius of the rotating ball head 57 and less than the structural diameter of the rotating ball head 57. The axis of the punch rod 510 is on the same straight line as the axis of the punch hole 514. The structural radius of the driven block 59 is adapted to the structural radius of the inner movable cavity 515.

[0023] To prevent damage to drive motor 4 due to excessive rigidity of the photovoltaic bracket, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 A power output control mechanism 6 needs to be set up. Its structure includes a hollow disc 61 that can drive the crankshaft 52 to rotate, an inner rotating column 610 that can rotate, and an arc-shaped contact plate 69 that can link the hollow disc 61 and the inner rotating column 610 by friction. Once the cutting resistance or punching resistance is greater than the force formed by the maximum static friction between the inner rotating column 610 and the arc-shaped contact plate 69, a relative rotation phenomenon occurs between the hollow disc 61 and the arc-shaped contact plate 69, which will not cause the torque resistance to continue to increase, thereby preventing damage to the drive motor 4.

[0024] For details regarding the specific structure of the power output control mechanism 6, please refer to [link / reference]. Figure 5 , Figure 6 and Figure 7 It also includes a hollow disk 61 and an inner rotating column 610. One end face of the hollow disk 61 is provided with a second docking plate 62 fixedly connected to the rotor of the drive motor 4. A cylindrical component mounting cavity 63 is provided at the center of the hollow disk 61. A shaft mounting hole 64 is provided at the center of one end of the hollow disk 61. The shaft of the rotating shaft 42 is mounted inside the shaft mounting hole 64 via a bearing. The inner rotating column 610 is placed at the center of the cylindrical component mounting cavity 63. A shaft fixing groove 611 for mounting the rotating shaft 612 is provided at the center of one end of the inner rotating column 610. A third docking plate 613 fixedly connected to another first docking plate 53 is fixedly mounted at one end of the rotating shaft 612. Multiple annular array-shaped longitudinal component movable cavities 65 are provided around the cylindrical component mounting cavity 63 of the hollow disk 61. The hollow disc 61 is connected to the circumferential side of the cylindrical component mounting cavity 63 through a first shaft through hole 66. An inner movable plate 67 capable of moving along the axial direction of the cylindrical component mounting cavity 63 is placed inside the cylindrical component mounting cavity 63. A helical spring 68 is placed at one end of the inner movable plate 67, and a connecting shaft passing through the first shaft through hole 66 is fixedly installed at the other end of the inner movable plate 67. An arc-shaped abutting plate 69 that abuts against the circumferential surface of the inner rotating column 610 is fixedly installed at one end of the connecting shaft located inside the cylindrical component mounting cavity 63. One end of the helical spring 68 abuts against one end face of the inner movable plate 67, and the other end abuts against one end face of the longitudinal component movable cavity 65. The helical spring 68 is in a compressed state. The structural radius of the concave surface of the arc-shaped abutting plate 69 matches the structural radius of the inner rotating column 610.

[0025] When in use, the drive motor 4 is started, and the rotor of the drive motor 4 drives the crankshaft 52 to rotate rapidly. The crankshaft 52 directly drives the cutting wheel 54 to rotate, thereby cutting the photovoltaic bracket. The rotating crankshaft 52 causes the movable connecting rod 56 to drive the driven block 59 to reciprocate and extend. During the directional movement of the driven block 59, the punch 510 at its tail will continuously adapt to the punch 514, thereby punching the photovoltaic bracket. Once the cutting resistance or punching resistance is greater than the force formed by the maximum static friction between the inner rotating column 610 and the arc-shaped contact plate 69, relative rotation occurs between the hollow disc 61 and the arc-shaped contact plate 69, which will not cause the torque resistance to continue to increase, thereby preventing damage to the drive motor 4.
