Detailed Implementation

[0013] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0014] like Figure 1-16 As shown, a pin-cutting device for inductor production is used to cut excess pins 11 on inductors 1 during the production process. It includes a frame 100 and a conveying mechanism 500 mounted on the frame 100. The inductor 1 is placed in the conveying mechanism 500 via a fixture 2. The conveying mechanism 500 includes a feeding conveying guide rail 510 and a defective material return guide rail 520. The feeding conveying guide rail 510 conveys the fixture 2 containing the inductor 1 to be cut along a first direction. The defective material return guide rail 520 conveys the fixture 2 containing defective inductors 1 along a direction opposite to the first direction. The feeding conveying guide rail 510 and the defective material return guide rail 520 operate on the same conveying principle and both utilize existing technology. The fixture 2 has a strip-shaped structure with multiple placement slots evenly spaced on its upper surface. Each placement slot can accommodate one inductor 1. The extension direction of the fixture 2 on the feeding conveying guide rail 510 or the defective material return guide rail 520 is parallel to the first direction. The inductor 1 includes an inductor body and two pins 11. The two pins 11 are symmetrically arranged and extend horizontally along a direction perpendicular to the first direction. Before cutting, the free end of each pin 11 extends out of the inductor body. The cutting device cuts off the part of the pin 11 that extends out of the inductor body. During processing, the inductor 1 is manually placed into the placement slot of the fixture 2 and then placed on the feeding conveyor rail 510.

[0015] The cutting equipment also includes a detection mechanism 200 mounted on the frame 100. The detection mechanism 200 includes a detection loading mechanism 210, a detection moving mechanism 220, a shooting mechanism 240, and a detection unloading mechanism 230 mounted on the frame 100.

[0016] The detection and feeding mechanism 210 is used to move the fixture 2 on the feeding conveying guide rail 510 to the detection moving mechanism 220. The detection and feeding mechanism 210 includes a detection and feeding module 211 mounted on the frame 100 and a first clamping mechanism 212 movably mounted on the output end of the detection and feeding module 211. The detection and feeding module 211 extends along a second direction perpendicular to the first direction and spans the feeding conveying guide rail 510 and the defective material return guide rail 520. The clamping action of the first clamping mechanism 212 is accomplished by a gripper cylinder in the prior art, and the up and down movement of the first clamping mechanism 212 is accomplished by an electric cylinder.

[0017] The detection moving mechanism 220 is used to receive the fixture 2 clamped by the detection feeding mechanism 210 from the feeding conveyor rail 510. The detection moving mechanism 220 includes a detection moving module 221 disposed on the frame 100 and a second clamping mechanism 222 disposed on the output end of the detection moving module 221. The detection moving module 221 is disposed between the feeding conveyor rail 510 and the defective material return rail 520. The second clamping mechanism 222 can move directly below the detection feeding module 211 to receive the fixture 2 on the first clamping mechanism 212. The detection moving module 221 extends along a first direction. The second clamping mechanism 222 includes a support plate 223 disposed on the output end of the detection moving module 221. A feeding groove for placing the fixture 2 is formed on the support plate 223 extending along a first direction. Clamping blocks 224 are disposed at both ends of the feeding groove. The two clamping blocks 224 can move back and forth along the first direction. When the fixture 2 is placed in the feeding groove, the two clamping blocks 224 move toward the fixture 2 to clamp the fixture 2.

[0018] The shooting mechanism 240 includes a camera 241 mounted on the frame 100. The camera 241 faces downward and is located directly above the detection moving mechanism 220. As the detection moving mechanism 220 moves along the first direction with the fixture 2, the inductors 1 move sequentially to directly below the camera 241. The camera 241 takes pictures of each inductor 1. By processing the pictures, it is possible to determine whether the inductor 1 is qualified. The method of image processing can use existing technology and the image processing method is not the content to be protected by this patent.

[0019] The detection unloading mechanism 230 has the same structure as the detection loading mechanism 210. Along the movement direction of the inductor 1 on the loading conveyor rail 510, the detection unloading mechanism 230 is downstream of the detection loading mechanism 210. When one inductor on the fixture 2 is detected to be defective, the detection unloading mechanism 230 moves the corresponding fixture 2 to the defective material return rail 520. The defective material return rail 520 returns with the fixture 2 for manual processing. When all inductors 1 on the fixture 2 are detected to be qualified, the detection unloading mechanism 230 moves the fixture 2 from the detection moving mechanism 220 to the loading conveyor rail 510. The loading conveyor rail 510 moves downstream with the fixture 2.

[0020] The cutting equipment also includes a first cutting mechanism 300 and a second cutting mechanism 400 mounted on the frame 100. Along the conveying direction of the fixture 2 on the feeding conveying guide rail 510, the detection mechanism 200, the first cutting mechanism 300, and the second cutting mechanism 400 are arranged in sequence. The first cutting mechanism 300 and the second cutting mechanism 400 have the same structure and are used to cut the pins 11 on both sides of the inductor 1, respectively. In actual production, the two cutting mechanisms work at the same time to improve efficiency. Of course, only one cutting mechanism can also be used.

[0021] The first cutting mechanism 300 includes a cutting and loading / unloading mechanism 310 mounted on the frame 100. The cutting and loading / unloading mechanism 310 includes a loading / unloading module 311 mounted on the frame 100 and a third clamping mechanism 312 rotatably mounted on the output end of the loading / unloading module 311 along a vertical axis. The loading / unloading module 311 extends along a second direction and spans the loading conveyor rail 510. The third clamping mechanism 312 has the same structure as the first clamping mechanism 212. The rotation of the third clamping mechanism 312 is driven by a rotary cylinder, and the vertical movement of the third clamping mechanism 312 is driven by an electric cylinder. The third clamping mechanism 312 can clamp and rotate the fixture on the loading moving guide rail 510 by 90°.

[0022] The first cutting mechanism 300 further includes a cutting moving mechanism 313 disposed on the frame 100. The cutting moving mechanism 313 includes a cutting moving module 313 disposed on the frame 100 and a fourth clamping mechanism 316 disposed on the output end of the cutting moving module 313. The structure of the fourth clamping mechanism 316 is the same as that of the second clamping mechanism 222. The cutting moving module 313 extends along a second direction, and the fourth clamping mechanism 316 is used to receive the fixture 2 on the third clamping mechanism 312. The fixture 2 located on the fourth clamping mechanism 316 extends along the second direction.

[0023] The first cutting mechanism 300 further includes a plurality of cutters 317 disposed at the cutting station. The plurality of cutters 317 are arranged at equal intervals along a second direction. The number of cutters 317 is equal to the number of material feeding slots on the fixture 2, and the distance between adjacent cutters 317 is equal to the distance between adjacent material feeding slots on the fixture 2. The cutters 317 are capable of moving up and down. When the cutting moving mechanism 313 moves the fixture 2 to the cutting station, the inductors 1 on the fixture 2 correspond one-to-one with the cutters 317. When the cutters 317 move downward, they can cut off the excess portion of the pins 11. The up and down movement of the cutters 317 is driven by a linear module.

[0024] The first cutting mechanism 300 further includes a pressing mechanism 315 disposed at the cutting station. The pressing mechanism 315 includes multiple pressing heads 319, which are arranged at equal intervals along a second direction. The number of pressing heads 319 is the same as the number of inductors 1 on the fixture 2. When the fixture 2 moves to the cutting station, the pressing heads 319 and the inductors 1 on the fixture 2 are aligned one-to-one in the first direction and at the same height. Viewed from above, the pressing heads 319 and the cutter 317 are located on opposite sides of the inductors 1. The pressing heads 319 can move back and forth along the first direction. During cutting, the pressing heads 319 move toward the corresponding inductor 1 and abut against the corresponding inductor 1. The cutter 317 cuts the pin 11 from the other side of the inductor 1, preventing the inductor 1 from moving during cutting. The pressing heads 319 are driven by a cylinder. A groove is provided on the end face of the pressure head 319 near the inductor 1, which can cooperate with the side of the inductor 1, so that the pressure head 319 and the inductor 1 can cooperate better.

[0025] The first cutting mechanism 300 further includes a wire end collection mechanism 318 disposed at the cutting station on the frame 100, for collecting the excess portion of the cut-off pin 11. The wire end collection mechanism 318 includes a wire end clamping mechanism and a collection box 3181 disposed on the frame 100. The wire end clamping mechanism is used to clamp the excess portion of the pin 11 to be cut before cutting. The wire end clamping mechanism includes a stationary part 3182 and a movable part 3183. The movable part 3183 is located directly above the stationary part 3182 and can move up and down. When the movable part 3183 moves downward, it can clamp the excess portion of the pin 11. The wire end clamping mechanism can move back and forth along the first direction. When it is necessary to clamp the excess part of the pin 11, the wire end clamping mechanism moves towards the inductor 1. After clamping, the cutter 317 starts to cut. After cutting, the wire end clamping mechanism moves away from the inductor 1, so that the excess part of the cut-off pin 11 moves directly above the receiving box 3181. Then the wire end clamping mechanism is released, so that the excess part of the cut-off pin 11 falls into the receiving box 3181.

[0026] After the first cutting mechanism 300 completes the cutting, the pressing head 319 moves away from the inductor 1, the cutting and transferring mechanism 313 returns with the fixture 2, and the cutting and unloading mechanism 310 places the fixture 2 back onto the loading conveyor rail 510. The loading conveyor rail 510 then moves the fixture 2 to the position of the second cutting mechanism 300, which cuts the excess portion of the pin 11 on the other side of the inductor 1. After cutting, the fixture 2 is placed back onto the loading conveyor rail 510 for subsequent processing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
