Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and specifically to a solar photovoltaic frame processing device. Background Technology

[0002] The solar photovoltaic frame is one of the core structural components of a photovoltaic module. It is mainly used to fix and protect the solar panels and enhance the overall mechanical strength and sealing of the module. The precision of its processing directly affects the installation of the photovoltaic module.

[0003] In existing solar photovoltaic frame processing technologies, different parts of the photovoltaic frame are typically processed sequentially using a single stamping die. In practice, the photovoltaic frame is manually placed on a fixed die, and stamping equipment is used to complete processes such as edge cutting, riveting, and through-hole punching one by one. After each process is completed, the photovoltaic frame must be removed, repositioned, and placed on the next die for further processing. This processing method relies heavily on manual labor, resulting in low production efficiency and significant errors in manual positioning, making it difficult to guarantee processing accuracy and leading to inconsistent product quality.

[0004] Furthermore, existing processing equipment lacks effective clamping and positioning devices when processing different sides of photovoltaic frames. During the stamping process, the photovoltaic frame is prone to displacement, affecting accuracy. Moreover, due to the fixed equipment structure, it is difficult to adapt to the processing needs of photovoltaic frames of different specifications, resulting in poor equipment versatility and increasing production and maintenance costs for enterprises. Therefore, there is an urgent need for a solar photovoltaic frame processing device that can improve processing efficiency, ensure processing accuracy, and has strong applicability. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a solar photovoltaic frame processing device. By setting a movable second end stamping die to cooperate with a fixed first end stamping die, and combined with cylinder drive, the two ends of the photovoltaic frame are quickly positioned and clamped. The flipping clamping mechanism is used to clamp and limit the B side of the photovoltaic frame. In conjunction with the end stamping die and the middle stamping die, the C side is simultaneously stamped in multiple processes, reducing manual intervention and process change time, thereby improving processing efficiency, ensuring processing accuracy and enhancing equipment versatility.

[0006] Technical Solution: This utility model provides a solar photovoltaic frame processing device including a worktable, a pair of end stamping dies including a first end stamping die and a second end stamping die, the first end stamping die and the second end stamping die being respectively disposed at both ends of the worktable, the first end stamping die being fixed on the worktable, and the second end stamping die being movably connected to the worktable; a cylinder, the cylinder being disposed on the worktable and on the side of the second end stamping die away from the first end stamping die, the output end of the cylinder being connected to the bottom of the second end stamping die, the cylinder being used to drive the second end stamping die to reciprocate on the worktable; a pair of middle stamping dies, the middle stamping dies being symmetrically disposed between the first end stamping die and the second end stamping die, the photovoltaic frame passing through the first end stamping die, the second end stamping die and the pair of middle stamping dies, when the cylinder drives the second end stamping die to move toward the first end stamping die, the two ends of the photovoltaic frame respectively abut against the first stop block provided on the first end stamping die and the second stop block provided on the second end stamping die. The second end stamping die is movably connected to the worktable and is driven by a cylinder to reciprocate on the worktable, allowing for flexible adjustment of the distance between the first and second end stamping dies. This design is adaptable to the processing of photovoltaic frames of different lengths, giving the device good versatility and flexibility. The use of stops ensures precise positioning of the photovoltaic frame, guaranteeing a fixed frame position during stamping and thus ensuring the accuracy and quality of the stamping process.

[0007] Furthermore, the solar photovoltaic frame processing device of this application also includes a flipping and pressing mechanism. The photovoltaic frame includes an A-side, a B-side, and a C-side. The flipping and pressing mechanism is used to press and limit the B-side of the photovoltaic frame after both ends of the photovoltaic frame are pressed together. A pair of end stamping dies and a pair of middle stamping dies perform stamping operations on the C-side. The pressing and limiting of the B-side of the photovoltaic frame ensures that the frame will not shift or deform due to force during the stamping process of the C-side. Precise limiting ensures that the relative positions between the components are fixed, providing a stable processing benchmark for the stamping dies, thereby achieving a high-quality C-side stamping effect and improving the overall processing accuracy of the product.

[0008] Furthermore, in this application, a solar photovoltaic frame processing device includes a flipping and pressing mechanism comprising a pair of second cylinders, a pair of connecting rods, a pair of gear racks, several connecting blocks, and several pressing blocks. The connecting blocks are correspondingly installed on one side of a pair of end stamping dies and a pair of middle stamping dies, extending outwards from the edge of the worktable. Each connecting block has a through hole through which the connecting rod passes. The pressing blocks are mounted on the connecting rods, which are parallel to the photovoltaic frame. The pair of second cylinders are respectively located on the side of the pair of middle stamping dies away from the first and second end stamping dies. The output end of each second cylinder is connected to a gear rack, and a gear is installed at the end of the connecting rod extending outwards from the connecting block. The gear meshes with the gear rack. The second cylinders drive the gear rack to slide, the gear rack drives the gear to rotate, which in turn drives the connecting rod to rotate. The pressing blocks mounted on the connecting rods flip and press against the B-side of the photovoltaic frame. This automatic flipping and pressing of the pressing blocks against the B-side of the photovoltaic frame achieves this effect. No manual operation is required, reducing labor intensity and ensuring consistency and stability in each clamping operation, thus guaranteeing the standardization of the processing. Since the connecting rod passes through the connecting block via perforations, the position of the connecting rod and the spacing of the pressure blocks can be flexibly adjusted according to the dimensions of different photovoltaic frame sizes to adapt to the processing needs of various photovoltaic frame models. Simultaneously, the drive parameters of the second cylinder can also be adjusted to change the clamping force, meeting the clamping force requirements of different processing techniques.

[0009] Furthermore, in a solar photovoltaic frame processing device of this application, a guide rail is provided on the worktable, and a slider is provided on the guide rail. The slider is connected to the bottom of the second end stamping die, and the output shaft of the cylinder is connected to the bottom of the second end stamping die. The cooperation of the guide rail and the slider provides precise linear motion guidance for the second end stamping die.

[0010] Furthermore, in this application, a solar photovoltaic frame processing device includes a first end stamping die and a second end stamping die, both comprising an arc-edge punch, a rivet punch, a grounding symbol punch, and a first through-hole punch. The arc-edge punch is used to cut the arc edge on the C-surface, the rivet punch is used to stamp the rivet on the C-surface, the grounding symbol punch is used to stamp the grounding symbol on the C-surface, and the first through-hole punch is used to punch through the C-surface to form a first through-hole. Each punch is designed for a specific processing part and shape. The arc-edge punch can accurately cut the arc-edge contour that meets the design requirements, the rivet punch can stamp the rivet with consistent specifications, the grounding symbol punch ensures that the grounding symbol pattern is clear and the size is accurate, and the first through-hole punch ensures that the position and diameter of the through-hole are accurate. Through these precise forming functions, the processing accuracy of each part of the photovoltaic frame is guaranteed, making it better suited for subsequent assembly and use requirements.

[0011] Furthermore, in a solar photovoltaic frame processing apparatus of this application, the central stamping die includes a universal hole punch, which is used to punch through the C-surface to form a universal hole. When the number of universal holes changes, several additional central stamping dies can be set between a pair of central stamping dies as needed, allowing for flexible adjustment.

[0012] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0013] 1. The solar photovoltaic frame processing device of this utility model achieves rapid positioning and clamping of both ends of the photovoltaic frame by setting a movable second end stamping die in cooperation with a cylinder. Combined with the limiting of the B side of the frame by the flipping and pressing mechanism, and the multi-process synchronous stamping of the C side by the end and middle stamping dies, manual intervention and process changeover time are reduced. Compared with the traditional method of processing with a single die in sequence, the processing efficiency is effectively improved.

[0014] 2. The solar photovoltaic frame processing device of this utility model provides precise linear motion guidance for the second end stamping die through a guide rail slider structure. Combined with the precise positioning of the stop block on the end stamping die and the stable limiting of the B-side by the flipping and clamping mechanism, the position of the photovoltaic frame is fixed during processing. At the same time, the punches designed specifically for each stamping die achieve precise forming, effectively avoiding processing deviations caused by displacement and positioning errors, and significantly improving processing accuracy.

[0045] Start cylinder 3 to push the second end stamping die 22 to the left, so that the two ends of the photovoltaic frame 5 are pressed against the first stop 211 and the second stop 221.

[0046] Step 2: Press side B firmly (52).

[0047] Start the second cylinder 61, push the gear rack 63 to drive the gear 66 to rotate, and drive the connecting rod 62 to rotate;
