[0030] The utility model will be further explained in detail below in combination with the drawings and specific embodiments. Specific embodiments

[0031] As Figures 1 to 8 shown, the embodiment of the utility model provides a capacitor pin straightening and cutting device, which can be used for automatic trimming, cutting and detection of the pin 120 of the capacitor 100. The device mainly comprises a feeding mechanism 200, a rotating transmission mechanism 300, a pin opening mechanism 400, a pin straightening mechanism 500, a capacitor detection mechanism 600, a pin cutting mechanism 700, a shooting mechanism 800 and a discharging mechanism 900.

[0032] The rotating transmission mechanism 300 comprises a rotating disc 310 and at least one first clamp 320 arranged on the rotating disc 310. The rotating disc 310 can rotate, for example, driven by a motor, and drive the first clamp 320 to sequentially pass through the feeding station 311, the pin opening station 312, the pin straightening station 313, the capacitor detection station 314, the pin cutting station 315, the shooting station 316 and the discharging station 317 within the range of one rotation of the rotating disc 310. The above stations are used in sequence to receive the capacitor 100 transferred from the previous process, for example, the laser marking process, open the two pins 120 of the capacitor 100, straighten the pins 120, test the capacitance between the pins 120, cut the pins 120, detect the appearance of the pins 120, and deliver the capacitor 100 to the next process. The rotating disc 310 drives the first clamp 320 to pass through the multiple stations in the circumferential direction, which is beneficial to reduce the space occupied by the device. The first clamp 320 is used to loosen or clamp the shell 110 of the capacitor 100. When the first clamp 320 clamps the shell 110 of the capacitor 100, the pins 120 of the capacitor 100 are exposed from the first clamp 320, which is convenient for trimming and testing the pins 120 of the capacitor 100. When the first clamp 320 loosens the shell 110 of the capacitor 100, the capacitor 100 can leave the station. The feeding mechanism 200 is used to move the capacitor 100 to the feeding station 311, so that the capacitor 100 is transferred from the previous process to the pin cutting process. The pin opening mechanism 400 cooperates with the pin opening station 312 and is used to open the two pins 120 of the capacitor 100, so that the two pins 120 are in a state of being separated outward, avoiding the two pins 120 approaching each other inward, which is convenient for using the mold 520 to straighten the pins 120 in the subsequent straightening process. The pin straightening mechanism 500 cooperates with the pin straightening station 313 and is used to straighten the pins 120. The pin straightening mechanism 500 can make the pins 120 extend perpendicular to one surface of the shell 110. The capacitor detection mechanism 600 cooperates with the capacitor detection station 314 and is used to detect the capacitance value between the two pins 120, i.e., the capacitance value of the capacitor 100. The pin cutting mechanism 700 cooperates with the pin cutting station 315 and is used to cut the pins 120 to obtain the required length. The shooting mechanism 800 faces the shooting station 316 and is used to shoot the pins 120, for example, to detect whether the length and extension direction of the pins 120 meet the standards. The discharging mechanism 900 cooperates with the discharging station 317 and is used to take the capacitor 100 out of the first clamp 320, which is convenient for the capacitor 100 to enter the next process.

[0033] In some examples, the feeding mechanism 200 includes a second clamp 220 for clamping or releasing the housing 110 of the capacitor 100, and a first moving mechanism 210 for moving the second clamp 220 between a position close to the feeding station 311 and a position away from the feeding station 311, for example, the first moving mechanism 210 can move the second clamp 220 in a horizontal direction. The second clamp 220 can clamp the part of the housing 110 of the capacitor 100 close to the lead 120, so as to facilitate the first clamp 320 clamping the part of the housing 110 of the capacitor 100 away from the lead 120.

[0034] In some examples, the lead spreading mechanism 400 includes a second moving mechanism 410 and two spreading plates 420 connected to the second moving mechanism 410, the second moving mechanism 410 is used to move the spreading plates 420 towards or away from the lead spreading station 312, for example, the second moving mechanism 410 can move the spreading plates 420 towards or away from the lead spreading station 312 in a direction perpendicular to the plane in which the two leads 120 are located. The two spreading plates 420 can move towards or away from each other. When the capacitor 100 reaches the lead spreading station 312, the second moving mechanism 410 moves the spreading plates 420 towards the lead spreading station 312, and the two spreading plates 420 move away from each other, thereby spreading the leads 120. When the capacitor 100 does not reach or leaves the lead spreading station 312, the second moving mechanism 410 moves the spreading plates 420 away from the lead spreading station 312, and the two spreading plates 420 move towards each other, thereby avoiding affecting the movement of the first clamp 320 and the capacitor 100 thereon, and preparing for spreading the next set of leads 120.

[0035] In some examples, the lead straightening mechanism 500 includes a third moving mechanism 510 and a lead straightening mold 520 connected to the third moving mechanism 510, the third moving mechanism 510 is used to move the lead straightening mold 520 towards or away from the lead straightening station 313, for example, the third moving mechanism 510 is used to move the lead straightening mold 520 towards or away from the lead straightening station 313 in a direction perpendicular to the plane in which the two leads 120 are located. The lead straightening mold 520 includes a middle module 521 and two side modules 522 arranged on both sides of the middle module 521, the side modules 522 can move towards or away from the middle module 521, when the side modules 522 move away from the middle module 521, the leads 120 can extend between the side modules 522 and the middle module 521, when the side modules 522 move towards the middle module 521, the leads 120 are clamped between the side modules 522 and the middle module 521 and are straightened.

[0036] In some examples, the capacitance detection mechanism 600 includes a third clamp 610 for clamping or unclamping the pins 120 of the capacitor 100, and a capacitance tester 620 including two sets of electrical contact tips 621 arranged on the third clamp 610 for contacting the two pins 120 respectively, and a capacitance tester body 622 connected with the electrical contact tips 621. The capacitance tester body 622 can be connected with the electrical contact tips 621 through wires. The electrical contact tips 621 can be arranged on the inner side of the third clamp 610. When the third clamp 610 is opened, the gap on the inner side of the third clamp 610 allows the pins 120 of the capacitor 100 on the first clamp 320 to pass through.

[0037] In some examples, the pin cutting mechanism 700 includes a fourth moving mechanism 710 and a cutter 720 connected with the fourth moving mechanism 710, the fourth moving mechanism 710 is used to drive the cutter 720 to move between a first position on one side of the plane where the two pins 120 are located and a second position where the two pins 120 of the capacitor 100 are located in the cutter 720, so as to achieve cutting without affecting the rotation of the capacitor 100 with the turntable 310. The cutter 720 includes a middle cutter 721 and side cutters 724 located on both sides of the middle cutter 721, the side cutters 724 can approach or move away from the middle cutter 721, when the side cutters 724 approach the middle cutter 721, the side cutters 724 contact the first end surface 722 of the middle cutter 721, the second end surface 723 of the middle cutter 721 opposite to the first end surface 722 is used to contact the shell 110 of the capacitor 100 between the two pins 120, that is, the middle cutter 721 is located between the side cutters 724 and the shell 110 during cutting, the distance between the first end surface 722 and the second end surface 723 of the middle cutter 721 is the length of the pin 120, so the middle cutter 721 can be used to limit the length of the pin 120.

[0038] In some examples, the middle blade 721 is detachable, and the pin cutting mechanism 700 further comprises a mounting block movably mounted on the fourth moving mechanism 710, and the middle blade 721 is detachably mounted on the mounting block. The middle blade 721 comprises a plurality of middle blades 721 with different distances between the first end surface 722 and the second end surface 723, i.e. the middle blade 721 can have different thickness specifications. The pin cutting mechanism 700 further comprises a fifth moving mechanism 730, and the fourth moving mechanism 710 is connected to the fifth moving mechanism 730, and the fifth moving mechanism 730 is used to drive the fourth moving mechanism 710 to move close to or away from the pin cutting station 315. For different specifications of the middle blade 721, the distance between the second end surface 723 of the middle blade 721 and the axis of the rotating disc 310 can be adjusted by the fifth moving mechanism 730, for example, the distance between the second end surface 723 of the middle blade 721 and the axis of the rotating disc 310 can be kept constant, which is beneficial to improve the length accuracy of the pin 120. The fifth moving mechanism 730 can comprise, for example, a manual knob, a threaded rod connected to the manual knob, a sliding block movably matched with the threaded rod, and a sliding rail matched with the sliding block, and the fourth moving mechanism 710 is connected to the sliding block.

[0039] In some examples, the rotating transmission mechanism 300 further comprises a sixth moving mechanism 330, and the sixth moving mechanism 330 is connected to the rotating disc 310 and the first clamp 320 is connected to the sixth moving mechanism 330, and the sixth moving mechanism 330 is used to drive the first clamp 320 to move close to or away from the axis of the rotating disc 310. When the first clamp 320 is located at the pin cutting station 315, the sixth moving mechanism 330 drives the first clamp 320 to move away from the axis of the rotating disc 310, so that the shell 110 of the capacitor 100 between the two pins 120 is in contact with the middle blade 721, thereby ensuring that the shell 110 of the capacitor 100 between the two pins 120 is in close contact with the middle blade 721, thereby improving the cutting length accuracy of the pin 120.

[0040] In some examples, when the first clamp 320 is located at the pin straightening station 313, the sixth moving mechanism 330 drives the first clamp 320 to move away from the axis of the rotating disc 310, and the shell 810 of the capacitor 100 between the two pins 120 is in contact with the middle module 521, thereby better straightening the pin 820.

[0041] In some examples, the pin cutting mechanism 700 further comprises a pin cutting material collecting mechanism 740 and a blowing mechanism, the pin cutting material collecting mechanism is arranged on one side of the cutter 720, and the blowing mechanism is used to blow the pin cutting material cut by the cutter 720 to the pin cutting material collecting mechanism 462. The blowing mechanism can be arranged on the other side of the cutter 720.

[0042] In some examples, the shooting mechanism 800 includes a camera 810 and a background plate 820, the camera 810 and the background plate 820 are oppositely arranged along a direction perpendicular to a plane on which the two pins 120 are located, and the background plate 820 is used to improve the definition of a photo taken by the camera 810.

[0043] In some examples, the discharging mechanism 900 includes a seventh moving mechanism 910, a rotating block 920, a fourth clamp 930, and a collecting tank 940. The collecting tank 940 is arranged below the discharging station 317, which can be located at the lower end of the rotating disc 310. The seventh moving mechanism 910 includes a first sliding block 911, a second sliding block 912, a connecting block 913, a first track 914, and a second track 915. The first track 914 is a straight track, and the first sliding block 911 is matched with the first track 914 and can move linearly on the first track 914. The second track 915 includes an arc-shaped track protruding away from the first track 914 in the middle, and the two ends of the second track 915 can be straight tracks. The second sliding block 912 is matched with the second track 915 and can move along the second track 915, including moving in the arc-shaped track. The rotating block 920 is rotatably connected to the first sliding block 911, the first end of the connecting block 913 is connected to the second sliding block 912, and the second end of the connecting block 913 is fixedly connected to the rotating block 920. When the first sliding block 911 moves, it drives the second sliding block 912 to move. When the second sliding block 912 moves to the arc-shaped track, the distance between the first sliding block 911 and the second sliding block 912 increases, the connecting block 913 rotates, thereby driving the rotating block 920 to rotate, and the overturning of the rotating block 920 can be realized. The fourth clamp 930 is connected to the rotating block 920, and the fourth clamp 930 is used to clamp or release the pins 120 of the capacitor 100.

[0044] When the rotating block 920 is located at the discharging station 317, the pins 120 of the capacitor 100 extend into the fourth clamp 930, the fourth clamp 930 clamps the pins 120, and the first clamp 320 releases the shell 110, thereby realizing the transfer of the capacitor 100. When the second sliding block 912 passes through the arc-shaped track, the seventh clamp overturns by 180°. When the rotating block 920 is located at the collecting tank 940, the rotating block 920 is rotated to the side of the shell 110 opposite to the pins 120 of the capacitor 100 clamped by the fourth clamp 930, and the side surface is in contact with the collecting tank 940, thereby realizing the overturning of the capacitor 100 and facilitating the transportation of the capacitor 100 in the subsequent process.

[0045] In some examples, the discharging mechanism 900 further includes a pushing rod 950, which can move along the collecting tank 940. The pushing rod 950 is used to push the capacitor 100 in the collecting tank 940, so that the capacitor 100 in the collecting tank 940 below the fourth clamp 930 is timely pushed away, which is conducive to the discharging of the next capacitor 100.

[0046] In some examples, the device further comprises a waste collecting mechanism 960, which may, for example, comprise a waste collecting funnel. The turntable 310 is further capable of driving the first clamp 320 to pass through a waste discarding station 318 located between the unloading station 317 and the loading station 311, i.e. the turntable 310 is further capable of driving the first clamp 320 to pass through the unloading station 317, the waste discarding station 318 and the loading station 311 in sequence. The waste collecting mechanism 960 is located below the waste discarding station 318. When the appearance of the pin 120 of the capacitor 100 captured by the capturing mechanism 800 does not meet the requirements or the capacitor detection mechanism 600 detects that the capacitance value of the capacitor 100 does not meet the requirements, the unloading mechanism 900 does not receive the capacitor 100, and when the capacitor 100 is rotated to the waste discarding station 318 by the turntable 310, the first clamp 320 releases the capacitor 100, and the defective capacitor 100 falls into the waste collecting mechanism 960.

[0047] In some examples, the device further comprises a display for displaying the picture captured by the capturing mechanism 800, so as to facilitate the operator to intuitively understand the appearance of the capacitor 100.
