Description

Technical Field

[0001] This invention relates to the field of photovoltaic bracket punching technology, specifically to an integrated multi-axis, multi-station tracking punching photovoltaic bracket production line. Background Technology

[0002] my country is one of the world's largest producers and consumers of coal. The vast amount of coal resources used are a major source of air pollution in my country. The construction of large-scale ground-mounted photovoltaic power stations is conducive to increasing the proportion of renewable energy. In the construction of photovoltaic power stations, a large number of photovoltaic brackets are required. The installation of these brackets is done by connecting them with screws, without the use of welding. The screw connection requires multiple holes to be made on each bracket, which requires a photovoltaic bracket punching device.

[0003] However, the existing photovoltaic bracket punching equipment has an adjustable punching structure, meaning it is mostly fixed. Since the holes for different specifications of photovoltaic brackets are also different, the existing fixed punching machines cannot be adapted to the different specifications of photovoltaic brackets for punching, resulting in significant production limitations. To address this, we designed an integrated multi-axis, multi-station tracking punching photovoltaic bracket production line to solve the above problems. Summary of the Invention

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0024] Please see Figure 1-8The present invention provides a technical solution: an integrated multi-axis multi-station tracking punching photovoltaic bracket production line, including a frame 1 with an installation groove 2 opened on the top in the horizontal direction, multiple sets of limiting members 8 are movably arranged on the top of the frame 1, each set of limiting members 8 has two members, and each set of limiting members 8 has a punching component on its top. A driving member for driving the punching component to move laterally is arranged in the installation groove 2. The driving component includes multiple sets of support members 3 set in the mounting groove 2. Each set of support members 3 consists of two members. The top of the support member 3 is provided with a bearing 4. A first lead screw 5 is rotatably provided between the two bearings 4 in each set in the horizontal direction. A first nut 6 is threaded onto the first lead screw 5. A connecting member 7 is fixedly provided on the first nut 6. The connecting member 7 is fixedly connected to one of the limiting members 8. A motor 9 is provided on one side of one of the support members 3 in each set. The drive shaft of the motor 9 is connected to one end of the first lead screw 5. Fixing strips 13 are provided at both the front and rear ends of the top of the frame 1 in the horizontal direction. A first protruding edge 14 is provided on one side of the fixing strip 13. A first fastening groove 15 adapted to the first protruding edge 14 is provided on both the front and rear sides of the bottom of the limiting member 8. The limiting member 8 is slidably sleeved on the first protruding edge 14 through the first fastening groove 15. The punching assembly includes a processing frame 18, a second protruding edge 17 is disposed on the side of the processing frame 18, a limiting member 8 is fixedly connected to the bottom of the processing frame 18, two cylinders 19 are symmetrically disposed on the top of the processing frame 18, the driving end of the cylinder 19 slides into the processing frame 18 and is provided with a mounting member 20, a fixing member 21 is disposed inside the mounting member 20, a plurality of cutting heads 22 are disposed at the bottom of the fixing member 21, and discharge ports 23 communicating with the interior are opened on both sides of the processing frame 18.

[0025] In practice, the steel strip that needs to be punched is passed through multiple processing frames 18 and slid out through the discharge port 23. Then, the steel strip is driven to move step by the rollers on the outside of the frame 1. During this process, the cylinder 19 needs to be turned on, so that the drive end of the cylinder 19 can extend and retract to drive the mounting part 20, the fixing part 21 and the cutter head 22 to move up and down, which can facilitate the shearing and punching of the steel strip below. During the above operation, by turning on the motor 9, the drive shaft of the motor 9 can drive the first lead screw 5 to rotate, so that the first nut 6 drives the connecting piece 7, the limiting piece 8 and the processing frame 18 to move horizontally. The spacing between different processing frames 18 can be easily adjusted to meet the punching requirements of photovoltaic brackets of different specifications. When the limiting piece 8 moves, it can slide on the first protrusion 14, which can limit the movement direction of the limiting piece 8 and prevent the limiting piece 8 from moving off course.

[0026] It should be noted here that, as can be seen from the above implementation, a symmetrically arranged ball bearing assembly is also required on one side of the steel strip punching device to move relative to each other and clamp the steel strip. The ball bearing assembly can be set in direction and position so that the punched steel strip can be folded into a frame. Finally, a cutting device is set on one side of the ball bearing assembly equipment to cut the photovoltaic frame. Since this application only relates to the punching production line, the subsequent processing will not be elaborated on.

[0027] Furthermore, it should be noted that in order to improve the accuracy of punching photovoltaic steel strips by the punching device, a control panel can be installed on the frame 1. The control panel is electrically connected to the electrical components on the punching device, so that the switching and operating status of the electrical components can be controlled. In addition, an algorithm chip needs to be embedded in the control panel. The algorithm chip can calculate the displacement of the steel strip during punching. When the steel strip deviates from its original position, the control panel can control the multiple processing frames 18 to adjust the spacing between them, thereby ensuring the punching accuracy of the steel strip.

[0028] See Figure 1-8 Each punching assembly has a motor 10 on one side along the horizontal direction. The drive shaft of the motor 10 is fixedly equipped with a gear 11. Each set of limiting members 8 has a rack 12 on the top of one side along the horizontal direction. The gear 11 and the rack 12 are meshed and connected. Each set of two limiting members 8 has a second groove 16 on the opposite side along the horizontal direction. Both sides of the punching assembly have a second protrusion 17 that matches the second groove 16. The second protrusion 17 is slidably inserted into the second groove 16.

[0029] In specific implementation, based on the above implementation, by turning on the motor 10, the motor 10 can drive the gear 11 to rotate. At the same time, the gear 11 meshes with the rack 12 and moves vertically and horizontally in the direction set in the second slot 16, which can further adjust the position of the processing frame 18, thereby further meeting the punching requirements of photovoltaic brackets of different specifications.

[0030] See Figure 1-8 The mounting component 20 has a through slot 24 and a guide slot 25. A positioning box 26 is slidably inserted into the guide slot 25. The fixing component 21 is slidably inserted into the slot 24 and fixedly connected to one side of the positioning box 26. A guide opening 27 connected to the guide slot 25 is opened on one side of the mounting component 20 in the horizontal direction. A pull component 28 is provided on one side of the positioning box 26 and is slidably inserted into the guide opening 27.

[0031] In specific implementation, based on the above implementation, by movably installing the fixing member 21 in the slot 24, pulling the pull member 28 can cause the pull member 28 to drive the positioning box 26, the fixing member 21 and the cutter head 22 to move along the direction of the slot 24. This not only adjusts the distance between multiple fixing members 21 and cutter heads 22, but also adjusts the number of fixing members 21 and cutter heads 22 in the mounting member 20, and adjusts the number and spacing of punches on the steel strip, thereby further meeting the punching requirements of photovoltaic brackets of different specifications.

[0032] See Figure 1-8 A motor 29 is fixedly installed horizontally at the center of the inner wall of the positioning box 26. The drive shaft of the motor 29 is provided with a second lead screw 30. The other end of the second lead screw 30 is rotatably installed inside the positioning box 26. Two second nuts 31 are symmetrically threaded on the second lead screw 30. The top and bottom of the positioning box 26 are provided with mounting ports 34 that communicate with the interior. A stop block 32 is movably installed in the mounting port 34. A rotating part 33 is rotatably installed between the second nut 31 and the stop block 32. A guide rod 37 is also provided inside the positioning box 26. A sliding hole adapted to the guide rod 37 is opened in the second nut 31. The second nut 31 is slidably sleeved on the guide rod 37 through the sliding hole. The end of the stop block 32 away from the rotating part 33 abuts against the inner wall of the guide groove 25. The second nut 31 is provided with mounting bases 35 at both the top and bottom, and a fixed base 36 is provided at the center of one side of the abutment block 32. The mounting base 35 and the fixed base 36 are respectively provided with a first pin and a second pin. The two ends of the rotating part 33 are respectively rotatably sleeved on the first pin and the second pin.

[0033] In specific implementation, based on the above implementation, by turning on the motor 29, the drive shaft of the motor 29 can drive the second lead screw 30 to rotate, so that the two second nuts 31 move closer to each other along the direction set by the guide rod 37. During this process, the rotating part 33 will rotate slightly while pushing the abutment block 32 to slide out of the mounting port 34 until the abutment block 32 abuts against the inner wall of the guide groove 25, so that the positioning box 26 can be inserted into the guide groove 25 with an interference fit, thereby positioning the positioning box 26, the fixing part 21 and the cutter head 22, ensuring the stability of the cutter head 22 during punching.

[0034] See Figure 1-8 A telescopic rod 38 is rotatably provided between each pair of horizontally rotating parts 33. A limit seat 39 is provided on the opposite side of each pair of horizontally rotating parts 33. A third pin is provided in each of the two limit seats 39. The two ends of the telescopic rod 38 are respectively rotatably sleeved on the two third pins.

[0035] In practice, based on the above implementation, during the movement of the two rotating parts 33, the telescopic end of the limiting part 8 will extend and retract accordingly, which can enhance the stability between the two rotating parts 33 and prevent the rotating parts 33 from deforming.

[0036] Before use, all electrical components involved in the punching device, both inside and outside, need to be connected to an external power source, or a battery pack should be installed on the frame 1 and processing frame 18 in an area that does not obstruct other components. Then, the battery pack is connected to multiple electrical components through wiring. It is also necessary to avoid the wiring from becoming tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical components, thereby ensuring their normal operation and switching. Since connecting the electrical components to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0037] Working principle: When in use, the steel strip that needs to be punched is first passed through multiple processing frames 18 and slid out through the discharge port 23. Then, the steel strip is driven to move step by the rollers on the outside of the frame 1. During this process, the cylinder 19 needs to be turned on, which can make the drive end of the cylinder 19 extend and retract, driving the mounting part 20, the fixing part 21 and the cutter head 22 to move up and down, which can facilitate the cutting and punching of the steel strip below.

[0038] During the above operation, by turning on the motor 9, the drive shaft of the motor 9 can drive the first lead screw 5 to rotate, so that the first nut 6 drives the connecting piece 7, the limiting piece 8 and the processing frame 18 to move horizontally. The spacing between different processing frames 18 can be easily adjusted to meet the punching requirements of photovoltaic brackets of different specifications. When the limiting piece 8 moves, it can slide on the first protrusion 14, which can limit the movement direction of the limiting piece 8 and prevent the limiting piece 8 from moving off course.

[0039] In addition, by turning on the motor 10, the motor 10 can drive the gear 11 to rotate. At the same time, the gear 11 meshes with the rack 12 and moves vertically and horizontally in the direction set in the second slot 16, which can further adjust the position of the processing frame 18, thereby further meeting the punching requirements of photovoltaic brackets of different specifications.

[0040] By movably installing the fixing member 21 in the slot 24, pulling the pull member 28 can cause the pull member 28 to drive the positioning box 26, the fixing member 21, and the cutter head 22 to move along the direction of the slot 24. This not only adjusts the distance between multiple fixing members 21 and cutter heads 22, but also adjusts the number of fixing members 21 and cutter heads 22 in the mounting member 20. This allows for adjustment of the number and spacing of punches on the steel strip, thereby further meeting the punching requirements of photovoltaic brackets of different specifications.

[0041] Finally, by turning on the motor 29, the drive shaft of the motor 29 drives the second lead screw 30 to rotate, causing the two second nuts 31 to move closer to each other along the direction set by the guide rod 37. During this process, the rotating part 33 will rotate slightly while pushing the abutment 32 to slide out of the mounting port 34 until the abutment 32 abuts against the inner wall of the guide groove 25, so that the positioning box 26 can be inserted into the guide groove 25 with an interference fit, thereby positioning the positioning box 26, the fixing part 21 and the cutter head 22, ensuring the stability of the cutter head 22 during punching.

[0042] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
