Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See attached document Figures 1-4 The present invention provides a punching mold for photovoltaic shingled welding strip, which includes a base 100 installed between a base 100 and a top plate 300. The base 100 is located below the top plate 300. The top corner of the outer wall of the base 100 is fixedly connected to the bottom of the outer wall of the top plate 300 by a vertical rod 310. A hydraulic telescopic rod 320 is installed at the center of the top of the outer wall of the top plate 300. The hydraulic telescopic rod 320 can perform punching operation on the photovoltaic shingled welding strip by controlling the upper punching mold 400 to move up and down.

[0023] A punching mechanism for punching photovoltaic shingled welding strips is provided on the opposite side of the base 100 and top plate 300, below the hydraulic telescopic rod 320. The punching mechanism includes a punching bottom mold 200. An installation groove is formed on the top of the outer wall of the base 100 below the hydraulic telescopic rod 320. The punching bottom mold 200 is fixed to the inner wall of the installation groove. A slag discharge groove 110 is formed on the inner wall of the base 100 below the punching bottom mold 200. Slag discharge holes are provided at the upper and lower ends of the outer wall and at positions corresponding to the mounting holes 402. The bottom end of the slag discharge holes is connected to the slag discharge trough 110. The waste generated by drilling will fall into the slag discharge trough 110 through the slag discharge holes. A waste slag conveyor belt 120 is fixed in the slag discharge trough 110 to discharge the waste slag from drilling the photovoltaic shingled strip. The waste falling into the slag discharge trough 110 will fall onto the waste slag conveyor belt 120. The waste slag conveyor belt 120 can discharge the waste after it is started.

[0024] The punching mechanism also includes a punching upper die 400, which is positioned above the top of the outer wall of the punching lower die 200. The punching upper die 400 is concave in shape. Elastic telescopic rods 410 are fixed to both sides of the bottom of the outer wall of the punching upper die 400, and clamping blocks 420 are fixed to the bottom of the outer wall of each elastic telescopic rod 410. The elastic telescopic rods 410 and clamping blocks 420 can clamp and fix the welding strip before punching, preventing the welding strip from shifting position during the punching process. Hexagonal grooves 401 are formed at the center of the top of the inner wall of the punching upper die 400, above the punching lower die 200. Multiple hexagonal grooves 401 are evenly arranged in an array. The center of the bottom of the inner wall of the hexagonal groove 401... Each part is provided with a mounting hole 402, and a punch 430 is slidably connected to the inner wall of each mounting hole 402. The mounting holes 402 allow the punch 430 to be connected to the punching die 400. The multiple mounting holes 402 allow the operator to select the appropriate position to install the punch 430 according to the requirements, thus adjusting the punching spacing. A hexagonal mounting block 431 is fixed to the top of the outer wall of each punch 430. The hexagonal mounting block 431 fits into the inner wall of the hexagonal groove 401. The hexagonal mounting block 431 is designed to cooperate with the hexagonal groove 401 to prevent the punch 430 from detaching from the mounting hole 402. Limiting strips 432 are fixed to the side of the outer wall of each punch 430. Multiple limiting strips 432 are... The punch 430 is uniformly arranged in a ring array. Limiting grooves 403 are provided on the inner wall of the mounting hole 402 at positions corresponding to the limiting strip 432. The outer wall of the limiting strip 432 is slidably connected to the inner wall of the limiting groove 403. The limiting strip 432 and limiting groove 403 serve two purposes: first, to prevent the punch 430 from wobbling within the mounting hole 402 during drilling; and second, to prevent the punch 430 from wobbling when drilling holes of different diameters, which requires adjustment of the punch 430's diameter. This is achieved by fixing the limiting strip 432 with the limiting groove 403 to the outer wall of the punch 430. The bottom output end of the hydraulic telescopic rod 320 passes through the bottom of the outer wall of the top plate 300. A fixing frame 330 is fixed to the end of the upper die 400. The bottom of the outer wall of the fixing frame 330 is fixedly connected to the top two sides of the outer wall of the upper die 400. The fixing frame 330 is set to fix the bottom of the hydraulic telescopic rod 320 to the top of the outer wall of the upper die 400. It can also work with the upper die 400 to limit the position of the fixing block 440. A fixing block 440 is set between the top of the outer wall of the upper die 400 and the top of the inner wall of the fixing frame 330 to press and fix the punch 430. The bottom of the fixing block 440 can be matched with the top of the upper die 400. In this way, when the fixing block 440 is installed, the punch 430 will not move upward during the punching process, thus ensuring the stability of the punching.

[0025] The usage process of this utility model is as follows: First, the operator can select a punch 430 of appropriate size according to the punching diameter required for the photovoltaic shingled strip, and place the punch 430 in the appropriate mounting hole 402 according to the punching spacing, so that the limiting strip 432 and the limiting groove 403 are fitted and connected. After the punch 430 is placed, the operator can take out the fixing block 440 and place the fixing block 440 between the punching upper die 400 and the fixing frame 330, so that the bottom end of the fixing block 440 can press and fix the punch 430. The fixing block 440 can be press-fitted with the punching upper die 400 and the fixing frame 330 to prevent the fixing block 440 from falling off during the punching process.

[0026] After the punch 430 and the fixed pressure block 440 are completed, the personnel can place the photovoltaic shingled welding strip on the punching bottom mold 200. The base 100 is equipped with an electrically controlled winding and unwinding device for the photovoltaic shingled welding strip to ensure that the photovoltaic shingled welding strip moves on the punching bottom mold 200. When the photovoltaic shingled welding strip moves to the punching point, the electrically controlled winding and unwinding device can be turned off first. Then, the hydraulic telescopic rod 320 will drive the fixed frame 330 and the punching upper mold 400 to move downward through the output end. The punch 430 will cooperate with the slag discharge hole on the punching bottom mold 200 to punch the photovoltaic shingled welding strip. The waste slag generated after punching will fall into the waste slag conveyor belt 120 through the slag discharge hole, so that the waste slag conveyor belt 120 can continuously discharge the waste slag after being energized. After punching is completed, the hydraulic telescopic rod 320 retracts, causing the punching upper mold 400 to move upward and reset. The photovoltaic shingled welding strip will continue to move to the next punching point for punching.
