Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1, as Figure 1-4As shown, the present invention provides a technical solution: a rectifier bridge automatic cutting device, comprising a base 1, a fixed track 2 and a rotating shaft 4, a fixed track 2 is installed at the top of the base 1, and a return-shaped slide groove 3 is opened on the outer wall of the fixed track 2, a slide groove is opened on the top of the fixed track 2, and a top frame 15 is arranged inside the slide groove, a slider 24 adapted to the slide groove is arranged below the top frame 15, a transmission rod 25 adapted to the return-shaped slide groove 3 is installed on one side of the top frame 15, a lifting and shifting mechanism for adjusting the top frame 15 is arranged inside the fixed track 2, and the lifting and shifting mechanism comprises a rotating shaft 4 and a transmission connecting plate 5, a rotating shaft 4 is installed inside the fixed track 2 through a bearing, and a transmission connecting plate 5 penetrating the transmission rod 25 is installed on the outer wall of the rotating shaft 4, a second motor 23 is arranged on the outer wall of the fixed track 2, and the output end of the second motor 23 is connected to one end of the rotating shaft 4 through a coupling, and a triangular rubber block 16 is arranged below the top frame 15. , an infrared sensor 26 is provided on the inner wall of the return-shaped slide 3, and a single-chip microcomputer 20 is provided on the top of the base 1. The output end of the infrared sensor 26 is electrically connected to the input end of the single-chip microcomputer 20 through a wire, and the output end of the single-chip microcomputer 20 is electrically connected to the input end of the cylinder 9 through a wire. By starting the second motor 23 to drive the rotating shaft 4 to rotate, the rotating shaft 4 drives the transmission connecting plate 5 to rotate, and then the transmission connecting plate 5 drives the transmission rod 25 to slide in the return-shaped slide 3, so that the top frame 15 drives the slider 24 to shift on the fixed track 2. At this time, the top frame 15 drives the triangular rubber block 16 to fit the position of the rectifier bridge component 13, and the transmission rod 25 moves upward to the highest position in the return-shaped slide 3. The triangular rubber block 16 does not contact the rectifier bridge component 13. When the transmission rod 25 rotates to the lowest position after the other side, the rectifier bridge component 13 is pushed to perform intermittent and equidistant feeding, and the cylinder 9 moves up and down to improve the processing efficiency.

[0025] Embodiment 2, as Figure 1-5As shown, the present invention provides a technical solution: an automatic slitting device for a rectifier bridge, comprising an L-shaped positioning frame 6 installed on one side of a base 1 close to a fixed track 2, and a rectifier bridge component 13 is arranged on the inner wall of the L-shaped positioning frame 6, an arc-shaped slide groove is provided on the inner wall of the L-shaped positioning frame 6, and a positioning ball 12 is arranged inside the arc-shaped slide groove, a groove 17 is provided inside the base 1, and a feeding mechanism is arranged inside the groove 17, a mounting frame 7 is installed on the top of the base 1, and positioning rods 8 are installed on both sides of the mounting frame 7, the outer wall of the positioning rod 8 is sleeved with a push plate 10, a cross-shaped slitting blade 11 is arranged below the push plate 10, and a longitudinal slitting blade is arranged at the middle position of the bottom end of the cross-shaped slitting blade 11, and the outer wall of the positioning rod 8 is sleeved with a spring 14, and the two sides of the spring 14 The sides are respectively connected to the side walls of the base 1 and the push plate 10, a cylinder 9 is arranged at the bottom end of the mounting frame 7, and the output end of the cylinder 9 is connected to the top of the push plate 10, the feeding mechanism includes a side wall slide rail 19 and a screw rod 21, side wall slide rails 19 are installed on both sides of the groove 17, a screw rod 21 is installed inside the groove 17 through a bearing, and a push block 22 adapted to the inside of the side wall slide rail 19 is arranged on the outer wall of the screw rod 21, a first motor 18 is arranged at the front end of the base 1, and the output end of the first motor 18 is connected to one end of the screw rod 21 through a coupling, and the screw rod 21 is driven to rotate by starting the first motor 18, so that the screw rod 21 drives the push block 22 to move forward and backward in the side wall slide rail 19, and then the push block 22 pushes the rectifier bridge component 13 to move to the bottom of the top frame 15 for feeding.

[0026] Working principle: First, turn on the external power supply, and after the rectifier bridge component 13 is taken to the position above the base 1 by the external robotic arm, the operator starts the first motor 18 to drive the screw rod 21 to rotate, so that the screw rod 21 drives the push block 22 to move forward and backward in the side wall slide rail 19, and then the push block 22 pushes the rectifier bridge component 13 to move to the bottom of the top frame 15 for loading. Then, start the second motor 23 to drive the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the transmission connecting plate 5 to rotate, and then the transmission connecting plate 5 drives the transmission rod 25 to move downward in the return-shaped slide groove 3 to the triangular rubber block 16 at the top frame 15 and contacts with the rectifier bridge component 13. It can be seen from the movement trajectory of the transmission rod 25 in the return-shaped slide groove 3 that the triangular rubber block 16 pushes the rectifier bridge component 13 to move below the cross-shaped slitting blade 11 After reaching the position, the transmission rod 25 moves upward and separates from the rectifier bridge components 13. At the same time, the slider 24 moves in the slide groove above the fixed track 2, and the infrared sensor 26 detects the passage of the transmission rod 25 and feeds back the information to the single-chip microcomputer 20. At this time, the single-chip microcomputer 20 starts the cylinder 9 to push the cross-shaped slitting blade 11 and the longitudinal slitting blade under the push plate 10 to perform horizontal and longitudinal slitting between the rectifier bridge components 13. When the transmission rod 25 moves upward to a certain distance and then moves downward, the triangular rubber block 16 fits with the position of the next group of rectifier bridge components 13. Since the moving distance in the return slide groove 3 is equal, the feeding distance is the same each time. This structure is convenient for automatic equal-pitch feeding and cutting of the rectifier bridge components 13, reduces the operation of operators, speeds up the processing speed, and improves production efficiency.
