Description

Technical Field

[0027] like Figure 1 As shown, the adjustable cutting structure includes a first motor 3 fixedly connected to the upper surface of the mounting frame 2, a connecting rod 4 fixedly connected to the output shaft of the first motor 3, a transmission gear 5 fixedly connected to the right end of the connecting rod 4, a driven gear 6 engaged with the bottom of the transmission gear 5, a rotating rod 7 fixedly connected to the inner side of the center of the driven gear 6, a connecting frame 8 fixedly connected to the bottom end of the rotating rod 7, a second motor 9 fixedly connected to the right side of the connecting frame 8, a first threaded rod 10 fixedly connected to the output shaft of the second motor 9, a first threaded block 11 threadedly connected to the outside of the first threaded rod 10, a mounting plate 12 fixedly connected to the front and back sides of the first threaded block 11 respectively, a first cylinder 13 fixedly connected between the opposite side walls of the front and rear mounting plates 12, and a cutter 14 fixedly connected to the bottom end of the piston rod of the first cylinder 13.

[0028] A positioning component for positioning the photovoltaic film is provided on the inner side of the fixing groove of the workbench 1 .

[0029] It should be noted that a mounting opening is provided on the top of the mounting frame 2 , and a rotation auxiliary frame 15 adapted to the connecting rod 4 is fixedly connected to the inner side of the mounting opening, and the connecting rod 4 is rotatably connected to the inner side of the rotation auxiliary frame 15 .

[0030] The left end of the first threaded rod 10 sequentially passes through the right side wall of the connecting frame 8 and the threaded hole of the first threaded block 11 and is rotatably connected to the inner left side wall of the connecting frame 8 .

[0031] A guide groove is provided on the inner side of the first threaded block 11, and the guide groove is located above the threaded hole, and a guide rod 16 is slidably connected to the inner side of the guide groove. The left end of the guide rod 16 is fixedly connected to the inner left wall of the connecting frame 8, and the right end of the guide rod 16 is fixedly connected to the inner right wall of the connecting frame 8.

[0032] The positioning assembly includes a placement platform 17 arranged on the inner side of the fixing groove, a second threaded rod 18 rotatably connected to the inner left and right walls of the placement platform 17 respectively, a toggle wheel 19 fixedly connected between the opposite ends of the second threaded rods 18 on the left and right sides, a second threaded block 20 threadedly connected to the outer side of the second threaded rod 18, two sliding rods 21 fixedly connected to the upper surface of the second threaded block 20, a connecting plate 22 fixedly connected between the top ends of the two sliding rods 21 on the same side, two second cylinders 23 fixedly connected to the upper surface of the connecting plate 22, a fixing plate 24 fixedly connected to the top end of the piston rod of the second cylinder 23, a fixing rod 25 fixedly connected to the bottom of the fixing plate 24, and a pressure block 26 fixedly connected to the bottom end of the fixing rod 25.

[0033] The four corners of the bottom of the placement table 17 are fixedly connected to the insertion rods 27, and the four corners of the bottom wall of the fixing groove are respectively provided with slots adapted to the insertion rods 27. This design facilitates the disassembly and assembly of the positioning assembly, thereby facilitating the replacement and maintenance of the various components of the positioning assembly.

[0034] The upper surface of the placement table 17 is provided with a cross cutting groove adapted to the blade of the cutting machine 14 , and the upper surface of the placement table 17 is provided with four sliding grooves adapted to the slide bar 21 . The design of the cross cutting groove prevents the cutting machine 14 from damaging the workbench 1 .

[0035] The two sliding rods 21 on the same side are sequentially arranged along the front-to-back direction of the second threaded block 20 on the same side, and the two second cylinders 23 on the same side are sequentially arranged along the front-to-back direction of the connecting plate 22 on the same side.

[0036] In addition, the transmission gear 5 and the driven gear 6 are both bevel gears, and the first motor 3 and the second motor 9 are both servo motors.

[0037] The working principle of the above embodiment is:

[0038] First, by starting the first motor 3, its output shaft drives the connecting rod 4 and the transmission gear 5 to rotate, and the transmission gear 5 engages with the driven gear 6, thereby driving the driven gear 6 and the rotating rod 7 inside the center of the circle to rotate, and the connecting frame 8 at the bottom of the rotating rod 7 rotates accordingly, and the first cylinder 13 and the cutter 14 installed at the bottom of the connecting frame 8 also rotate, thereby adjusting the cutting direction. Next, the first cylinder 13 is started, and the first cylinder 13 drives the cutter 14 to move downward, so that the blade of the cutter 14 contacts the photovoltaic film. Then, the cutter 14 is started to rotate the blade of the cutter 14, and the photovoltaic film starts to be cut. And in this process, the second motor 9 is started, and the output shaft of the second motor 9 drives the first threaded rod 10 to rotate. Since the first threaded rod 10 is threadedly connected to the first threaded block 11, and the guide groove provided on the inner side of the first threaded block 11 is slidably connected to the guide rod 16, the first threaded block 11 moves axially along the first threaded rod 10 under the action of the thread, and is guided by the guide rod 16 to ensure the stability and accuracy of the movement process. During the movement, the first threaded block 11 drives the mounting plate 12 to move, and then drives the first cylinder 13 and the cutting machine 14 to move through the mounting plate 12, thereby adjusting the cutting position;

[0039] When the photovoltaic film needs to be positioned, the toggle wheel 19 is first rotated. The rotation of the toggle wheel 19 drives the synchronous rotation of the second threaded rods 18 on the left and right sides. Since the second threaded rods 18 are threadedly connected to the second threaded block 20, the second threaded block 20 moves axially along the second threaded rod 18 under the action of the threads. The two slide rods 21 fixedly connected to the upper surface of the second threaded block 20 move accordingly. The top of the slide rod 21 is connected to the connecting plate 22, so the connecting plate 22, the second cylinder 23, the fixed plate 24 and the pressure block 26 also move as a whole. When the pressure block 26 moves to the appropriate position, the second cylinder 23 is activated, and the piston rod of the second cylinder 23 extends, driving the fixed plate 24 and the pressure block 26 downward, firmly fixing the photovoltaic film on the placement platform 17.
