Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0022] like Figures 1 to 3 As shown, the punching mechanism includes an upper die assembly and a lower die assembly. The upper die assembly is mounted on the frame, and the lower die assembly is detachably mounted on the worktable 2 via a punching base plate 1. A base plate punching channel 3 is provided through the surface of the punching base plate 1. A waste collection device is located below the base plate punching channel 3. The base plate punching channel 3 allows waste to fall downwards into the waste collection device for collection. The punching base plate 1 is detachably connected to the T-slot on the worktable 2 by bolts, which allows for easy replacement of the entire lower die assembly.

[0023] The upper die assembly includes a punching cylinder 4, the cylinder body of which is fixed to the frame. A detachable upper punching template 5 is mounted on the telescopic end of the punching cylinder 4. Multiple punch rods 6 are arranged along the length of the photovoltaic bracket at the bottom of the upper punching template 5. The punch rods 6 can be replaced by replacing the upper punching template 5. The lower die assembly includes a lower punching module 7, the surface of which has multiple punching die holes 8 corresponding to the punch rods 6. During punching, the photovoltaic bracket is supported on the lower punching module 7. The punch rods 6, driven by the punching cylinder 4, descend and insert into the corresponding punching die holes 8. The punching die holes 8 cooperate with the punch rods 6 to achieve punching of the photovoltaic bracket.

[0024] A guiding device is provided between the upper die assembly and the lower die assembly. The guiding device includes a punching guide post 9 fixed to the lower die assembly. The upper punching template 5 is slidably fitted onto the punching guide post 9. Through the cooperation between the punching guide post 9 and the upper punching template 5, the upper die assembly can be guided, thereby improving the punching accuracy.

[0025] The lower punching module 7 has side positioning devices on its left and right sides that abut against both ends of the photovoltaic bracket. A punching rod guide plate 10 is also provided above the lower punching module 7. The distance between the punching rod guide plate 10 and the lower punching module 7 is greater than the waist thickness of the photovoltaic bracket. The punching rod guide plate 10 is detachably connected to the side positioning devices. The surface of the punching rod guide plate 10 is provided with multiple punching rod guide holes 11 that match the punch rod 6. The punching rod guide holes 11 are adapted to the size of the punch rod 6. The punch rod 6 is always inserted into the punching rod guide hole 11 and can slide up and down along the punching rod guide hole 11 to achieve the purpose of guiding the punch rod 6. In conjunction with the guiding device, it can further improve the punching accuracy.

[0026] In this embodiment, six punch rods 6 are evenly distributed, and correspondingly, six punch rod die holes 8 and six punch rod guide holes 11 are provided, ensuring that six mounting holes can be processed on the photovoltaic bracket at one time. The bottom end of the punch rod 6 has a V-shaped structure.

[0027] To facilitate the processing of mounting holes of different sizes and spacings on photovoltaic brackets, existing technologies generally require the replacement of the entire lower mold, which results in high equipment costs and is complex and difficult to replace. Therefore, this embodiment improves the punching lower module 7 by splitting the existing integrated lower mold into two parts. Preferably, the punching lower module 7 includes a fixed support mold 7a, the top of which is provided with a detachable punching mold 7b. Multiple punching die holes 8 are provided on the detachable punching mold 7b. A lower die punching channel 7c is provided through the fixed support mold 7a, and the lower die punching channel 7c extends along the length direction of the photovoltaic bracket. The fixed support mold 7a serves merely as a support base, used to raise the height of the punching lower module 7 to accommodate the height of the photovoltaic bracket. The lower die punching channel 7c on it is used to avoid the punch rod 6. The detachable punching die 7b is fixed to the fixed support mold 7a by bolts. The punching die hole 8 is located on the detachable punching die 7b. By providing mounting holes of different specifications or in different numbers on the detachable punching die 7b, various specifications of detachable punching dies 7b can be formed to meet different processing needs. When different specifications of mounting holes need to be processed, it is not necessary to replace the entire punching lower module 7; instead, only the detachable punching die 7b needs to be removed and replaced. Simultaneously, the corresponding punching guide hole 11, the punching upper template 5, and the punch rod 6 can be replaced, thus meeting the need for multiple uses with a single machine. The replacement method is simple and low-cost.

[0028] The two side positioning devices work together to position the photovoltaic bracket in the left and right directions, and also serve as the mounting structure for the punch guide plate 10 bracket. Each side positioning device includes auxiliary side plates 12 located on the left and right sides of the punching lower module 7. Side limiting wheels 13 are rotatably mounted on the inner side of each auxiliary side plate 12 and are supported on the side surface of the photovoltaic bracket. At least two side limiting wheels 13 are arranged along the length of the same auxiliary side plate 12, and more are possible. The side limiting wheels 13 on the left and right sides are symmetrically positioned to simultaneously contact and abut against the left and right end faces of the photovoltaic bracket, thus positioning the photovoltaic bracket in the left and right directions and ensuring the accuracy of the punching position. The auxiliary side plate 12 has a mounting groove 14 at its top end. The punch guide plate 10 has guide plate brackets 15 at both ends, which are placed within the mounting groove 14. The width of the mounting groove 14 is greater than the width of the guide plate brackets 15. The auxiliary side plate 12 has limiting screws 16, the inner end of which abuts against the outside of the guide plate brackets 15. A fixing screw 17 is also provided between the auxiliary side plate 12 and the guide plate brackets 15. The limiting screws 16 on both sides work together to adjust the position of the guide plate brackets 15, thereby adjusting the left and right positions of the punch guide plate 10. This ensures that the position of the punch guide hole 11 accurately corresponds to the punch rod 6. After adjustment, the plate is fixed using the two fixing screws 17. The cooperation of the limiting screws 16 and the fixing screws 17 facilitates the disassembly, replacement, and positioning of the punch guide plate 10.

[0029] like Figure 4 As shown, the agricultural photovoltaic bracket punching equipment includes a frame with a worktable 2 on it. A punching mechanism is mounted on the worktable 2, and a waste collection device 18 is located below the punching mechanism. Positioning and clamping mechanisms 19 are located at the front and rear of the punching mechanism to press the photovoltaic bracket downwards. Before punching, the positioning and clamping mechanisms 19 first clamp the photovoltaic bracket in place, and then the punching mechanism punches the photovoltaic bracket. The waste material after punching is collected by the waste collection device 18. After punching is completed, the positioning and clamping mechanisms 19 are released, and the photovoltaic bracket continues to be conveyed forward a fixed length, ready for the next punching.

[0030] The positioning and pressing mechanism 19 includes a positioning bracket, a positioning cylinder is fixed at the top of the positioning bracket, a positioning pressure plate is fixedly connected to the telescopic end of the positioning cylinder facing downwards, an auxiliary support block is provided below the positioning pressure plate, and the top of the auxiliary support block is at the same level as the top of the punching module 7.

[0031] The waste collection device 18 includes a waste box. The workbench 2 is provided with a waste hole located below the punching mechanism and above the waste box. The waste box is inclined and its inclined bottom end extends to the side of the punching equipment.

[0032] The working principle of this embodiment is as follows:

[0033] When the photovoltaic bracket is transported to this equipment, the inner groove surface of the photovoltaic bracket slides forward along the auxiliary support block and passes through the gap between the detachable punch die 7b and the punch guide plate 10. When passing through, the left and right side limit wheels 13 abut against the left and right sides of the photovoltaic bracket. When the photovoltaic bracket moves into place, the transport stops, and the front and rear positioning cylinders extend, driving the positioning pressure plate to descend and press on the surface of the photovoltaic bracket, so that the inner surface of the photovoltaic bracket is tightly attached to the upper surface of the detachable punch die 7b, and the positioning is completed in cooperation with the left and right side limit wheels 13.

[0034] Then, the punching cylinder 4 actuates, causing the upper punching template 5 and the punch rod 6 to descend. The punch rod 6 descends along the punch rod guide hole 11, penetrates the photovoltaic bracket, and enters the lower die punch rod channel 7c through the punch rod die hole 8. The generated waste material falls into the waste box for collection through the waste material hole. After punching is completed, the punching cylinder 4 actuates, causing the upper punching template 5 and the punch rod 6 to rise and reset. The positioning cylinder drives the positioning pressure plate to retract, and the photovoltaic bracket continues to be conveyed forward a fixed length, ready for the next punching.

[0035] The vertical and horizontal positioning of the photovoltaic bracket is achieved by the positioning cylinder and the positioning pressure plate. The horizontal positioning of the photovoltaic bracket is achieved by the side limiting wheel 13. The positioning method is simpler, and the vertical and horizontal positioning is located outside the punching mechanism, which can reduce the structural complexity of the punching mechanism.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
