[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figure 1As shown, a resistor pin cutting device provided by the present invention includes a rotating shaft 1, a bearing 2 is inserted into the lower end of the rotating shaft 1, the bearing 2 is fixed to the ground by bolts, a disc 3 is welded above the rotating shaft 2, and two first driving members 4 are connected below the disc 3. The first driving member 4 can be an oil cylinder, an air cylinder or an electric push rod. In this embodiment, the first driving member 4 is an air cylinder, and the two cylinders are fixed to the lower side of the disc 3 by bolts.

[0021] A suction cup device 5 is connected below the driving rod of each first driving member 4, and the two suction cup devices 5 are arranged horizontally and vertically. Figure 2 As shown, the suction cup device 5 includes a mounting plate 5.1, a group of suction cups 5.2 are connected below the mounting plate 5.1, and an air pipe is connected above each suction cup 5.2 during installation, which is not shown in the accompanying drawings. The suction cups 5.2 are sucked and blown through the air pipe, thereby achieving adsorption and detachment from the resistor 10.

[0022] A driving device, a feeding device 6, a cutting device 7 and a discharging device 8 are respectively arranged on the four sides of the rotating shaft 1. The driving device and the cutting device 7 are arranged opposite to each other. The feeding conveyor belt 6 and the discharging conveyor belt 8 are arranged opposite to each other. Both the feeding device 6 and the discharging device 8 are conveyor belt devices. First placement grooves 6.1 are evenly distributed on the conveyor belt of the feeding device 6. In the present embodiment, the number of the first placement grooves 6.1 in each row is three, and a resistor 10 is placed in each first placement groove 6.1.

[0023] like Figure 2 As shown, the driving device is used to drive the rotating shaft 1 to rotate, and the driving device includes a hydraulic cylinder 9, which is fixed to the ground by bolts. The hydraulic cylinder 9 is horizontally arranged, and a rack 9.1 is welded on the piston rod of the hydraulic cylinder 9. A gear 1.4 is sleeved on the rotating shaft 1, and the gear 1.4 is engaged with the rack 9.1. The rotating shaft 1 is driven to rotate by the extension and retraction of the hydraulic cylinder 9. In this embodiment, the rotation angle of the rotating shaft 1 is 90 degrees, that is, when the piston rod of the hydraulic cylinder 9 is fully extended, the rotating shaft 1 rotates 90 degrees in the forward direction, and when the piston rod of the hydraulic cylinder 9 is fully retracted, the rotating shaft 1 rotates 90 degrees in the reverse direction.

[0024] When the piston rod of the hydraulic cylinder 9 is not extended, the first suction cup device 5 is located directly above the feeding device 6, and the second suction cup device 5 is located directly above the cutting device 7. When the feeding device 6 transports the resistor 10 to the bottom of the suction cup device 5, the feeding device 6 stops, and the two first driving members 4 are started to drive the suction cup device 5 to move downward to absorb the resistor 10, and then the first driving member 4 moves upward, and then the hydraulic cylinder 9 is started to rotate the rotating shaft 1 90 degrees in the positive direction, so that the first suction cup device 5 is located above the cutting device 7, and the second suction cup device 5 is located above the discharging device 8, and then the two first driving members are started. The first driving member 4 moves downward, places the resistor 10 to be cut into the cutting device 7, places the cut resistor 10 on the discharging device 8, and then starts the cutting device 7 to cut the pin 11 of the resistor 10. After cutting, the air pipe blows air to the suction cup 5.2 to separate the suction cup 5.2 from the resistor 10, and then starts the first driving member 4 to move upward, and then rotates the rotating shaft 1 90 degrees in the opposite direction, so that the first suction cup device 5 is directly above the feeding device 6, and the second suction cup device 5 is directly above the cutting device 7, and the resistor 10 is sucked again, and the operation is repeated to realize the automatic cutting of the resistor 10.

[0025] In order to improve the cutting accuracy of resistor 10, Figure 3 As shown, the cutting device 7 includes a support frame 7.1, which is fixed to the ground by bolts, a fixed plate 7.2 is welded above the support frame 7.1, and a group of second placement slots 7.3 are opened on the upper side of the fixed plate 7.2. The number of a group of second placement slots 7.3 is the same as the number of each row of first placement slots 6.1, that is, three, and a resistor 10 is placed in each second placement slot 7.3. Two sliding rods 7.11 are welded on one side of the fixed plate 7.2, and a movable plate 7.4 is slidably connected on the two sliding rods 7.11. Two through holes are opened on the movable plate 7.4 for plugging the sliding rods 7.11, and a group of plug-in slots 7.5 are arranged on the movable plate 7.4. The number of a group of plug-in slots 7.5 is twice the number of a group of second placement slots 7.3, that is, one second placement slot 7.3 is equipped with two plug-in slots 7.5, and a resistor 10 is placed in one second placement slot 7.3, and two pins 11 of the resistor 10 are plugged into the plug-in slots 7.5.

[0026] A limit plate 7.6 is connected to the end of each sliding rod, and the limit plate 7.6 limits the movable plate 7.4. A spring 7.12 is sleeved on each sliding rod 7.11, and one end of each spring 7.12 is welded to one side of the fixed plate 7.2, and the other end of each spring 7.12 is welded to one side of the movable plate 7.4.

[0027] A through hole is provided on the movable plate 7.4, and a bolt 7.7 is inserted into the through hole. A threaded blind hole is provided on the side of the fixed plate 7.2, and the threaded blind hole is coaxially arranged with the through hole. The bolt 7.7 is threadedly connected in the threaded blind hole. A mounting plate 7.8 is welded on one side of the movable plate 7.4, and a second driving member 7.9 is fixed to one side of the mounting plate 7.8 by bolts. The second driving member 7.9 can be a cylinder, an oil cylinder or an electric push rod. In the present embodiment, the second driving member 7.9 is an oil cylinder, and the oil cylinder is fixed to the side of the mounting plate 7.8 by bolts.

[0028] A cutting knife 7.10 is welded on the piston rod of the second driving member 7.9 so that one side of the cutting knife 7.10 is close to the moving plate 7.4 and the cutting direction of the cutting knife 7.10 is toward the pin 11. The cutting knife 7.10 is driven by the second driving member 7.9 to cut the pin 11.

[0029] When adjusting the length of the cutting pin 11, by screwing the bolt 7.7, the movable plate 7.4 moves under the action of the spring 7.12, thereby adjusting the length of the pin 11 extending out of the insertion slot 7.5. When the movable plate 7.4 moves, it also drives the second driving member 7.9 to move.

[0030] In order to facilitate the movement of the second driving member 7.9, a guide groove is provided at the bottom of the mounting plate 7.8, and a guide block 7.13 is slidably connected in the guide groove, and the guide block 7.13 is welded above the support frame 7.1.

[0031] Working principle: First, adjust the length of the pin 11 extending out of the plug-in slot 7.5 to improve the accuracy of pin cutting, and then drive the suction cup device 5 to move by rotating the rotating shaft 1, so that the two suction cup devices 5 move back and forth between the feeding device 6, the cutting device 7 and the discharging device 8, and absorb the resistor 10 through the suction cup device 5 to realize fully automatic pin cutting of the resistor 10.
