Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically to a cutting device for transistor production. Background Technology

[0002] The production of through-hole transistors usually involves bonding the leads to a metal frame, then sending the leads and the metal frame together into a molding machine for molding. After molding, the excess metal frame needs to be removed.

[0003] Furthermore, in the prior art, a metal frame is strip-shaped (e.g.) Figure 1 As shown in the figure, the multiple transistors after plastic sealing are connected into a strip, so it is necessary to cut the multiple transistors into individual pieces.

[0004] A utility model patent with patent number "CN 220128949 U" discloses a transistor strip slitting device, including a slitting machine table. The upper surface of the slitting machine table is provided with a slitting mechanism, a pushing mechanism, a feeding mechanism, and a discharging component. The pushing mechanism includes a fixed base, a pushing block, and a pushing cylinder. The fixed base includes a left transistor strip fixing plate, a right transistor strip fixing plate, and a baffle. Both the left and right transistor strip fixing plates are provided with transistor strip guide grooves. The guide grooves of the left and right transistor strip fixing plates are combined to form a transistor strip moving groove. The pushing block and the pushing cylinder are fixed at a position between the left and right transistor strip fixing plates, and the upper part of the pushing block is located in the middle position of the transistor strip moving groove.

[0005] In the aforementioned patent, the transistor strip in the guide groove is pushed by a pusher block and a pusher cylinder. Since the pusher cylinder pushes the object by extending the piston rod, the longer the pushing distance, the longer the pusher cylinder becomes, which can easily occupy the installation space of the equipment. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] A slitting device for transistor production includes a machine base 5. The machine base 5 is provided with a feeding seat 6 arranged in a straight line. The upper end of the feeding seat 6 is provided with a sliding groove that matches the transistor strip 1 along its length direction. The feeding seat 6 is arranged in sequence as a feeding part 24 and a slitting part 25 along the conveying direction of the transistor strip 1 (in reality, the feeding part 24 and the slitting part 25 can be integrated. The feeding part 24 and the slitting part 25 are separated in the attached drawings of this utility model for clearer display). The slitting part 25 is provided with a slitting mechanism.

[0028] The robotic arm picks up the transistor strip 1 and places it into the corresponding groove in the feeding section 24. Then, the transistor strip 1 is pushed into the slitting section 25 in the groove and slitting it into individual transistors by the slitting mechanism.

[0029] The feeding seat 6 has an inner hole 10 along its length. The bottom of the chute is connected to the inner hole 10 through a connecting port 12. The length of the connecting port 12 is set along the length of the chute. A sliding push rod 15 is matched in the connecting port 12. The upper end of the push rod 15 extends into the chute to push the transistor strip 1. The lower end of the push rod 15 extends into the inner hole 10. A slide rail 11 is provided in the inner hole 10. A sliding slider 26 is matched on the slide rail 11. The slider 26 is fixedly connected to the lower end of the push rod 15. The slider 26 is driven by a lead screw 13. The two ends of the lead screw 13 are rotatably located in the inner hole 10. The lead screw 13 passes through the slider 26 and is screwed to the slider 26. The lead screw 13 is connected to a motor 14.

[0030] Motor 14 drives lead screw 13 to rotate, thereby moving slider 26 and push rod 15. Push rod 15 abuts against the rear end of transistor strip 1, thereby pushing transistor strip 1 forward toward slitting section 25.

[0031] In this invention, the lead screw 13 drives the slider 26 to drive the push rod 15 to push the transistor strip 1. The length of the lead screw 13 can be directly adapted to the distance that the transistor strip 1 needs to move. Furthermore, the lead screw 13 will not move during the process of pushing the transistor strip 1. Compared with the method of pushing with the push cylinder 18, the length space occupied is reduced.

[0032] In a preferred embodiment, the slide includes a main slide 7 that matches the plastic housing 2 of the transistor, the communication port 12 is located at the bottom of the main slide 7, and a horizontal platform 8 for supporting the transistor pins 3 is provided on one side of the main slide 7; furthermore, in the feeding distribution, a secondary slide 9 corresponding to the metal frame 4 is provided on the side of the horizontal platform 8 away from the main slide 7; and in the cutting section 25, a second unloading groove 21 corresponding to the metal frame 4 is provided on the side of the horizontal platform 8 away from the main slide 7, and the second unloading groove 21 is inclined downwards.

[0033] When the transistor strip 1 is placed in the chute, the portion of the transistor strip 1 corresponding to the plastic housing 2 is embedded in the main chute 7, the pins 3 of the transistor strip 1 are supported on the horizontal platform 8, and the metal frame 4 of the transistor strip 1 is positioned in the secondary chute 9. After slitting, the metal frame 4 falls into the second unloading chute 21 and slides down under its own weight, thus automatically unloading the transistor.

[0034] In a preferred embodiment, the slitting mechanism includes a lower pressure plate 20, which is driven to rise and fall by a lifting mechanism. A blade is fixedly provided at the lower end of the lower pressure plate 20. A plurality of first cutters 27 and a plurality of second cutters 28 are spaced apart along the length of the slide groove at the lower end of the blade. The first cutters 27 correspond to the plastic housing 2 of the transistor, and the interval between two adjacent first cutters 27 matches the width of a single transistor plastic housing 2. The length direction of the first cutter 27 is perpendicular to the length direction of the transistor strip 1, and is used to slit multiple connected transistors on the transistor strip 1 into multiple single transistors. The second cutters 28 correspond to the leads 3 of the transistor and are used to cut off the leads 3 of the transistor, thereby cutting off the connection between the transistor and the metal frame 4 and removing the metal frame 4.

[0035] Driven by the lifting mechanism, the lower pressure plate 20 descends, and several first cutters 27 cut the transistor strip 1 into multiple individual transistors, while several second cutters 28 sever the connection between the transistors and the metal frame 4.

[0036] In a preferred embodiment, the lifting mechanism includes a mounting plate 17 fixedly mounted on the machine base 5 via a support frame 16. A vertical cylinder 18 is fixedly mounted on the mounting plate 17. A lower pressure plate 20 is located below the mounting plate 17 and is fixedly connected to the telescopic rod of the cylinder 18. Two guide rods 19 are also fixedly mounted on the lower pressure plate 20, respectively located on both sides of the cylinder 18. A guide sleeve adapted to the guide rods 19 is provided on the mounting plate 17.

[0037] In a preferred embodiment, the lower end of the blade is provided with a plurality of springs 29 corresponding to the transistor strip 1, and the plurality of springs 29 correspond one-to-one with each transistor on the transistor strip 1.

[0038] In its natural state, the lower end of the spring 29 is lower than the lower end of the first cutter 27. When the first cutter 27 descends to cut, the spring 29 first contacts the corresponding single transistor, so that the transistor can be pressed tightly by the spring 29 during cutting to prevent the transistor from shifting.

[0039] In a preferred embodiment, the end of the chute is connected to a first discharge chute, which is inclined downwards.

[0040] After the transistor strip 1 is cut into multiple individual transistors, the transistors are still in the chute. At this time, the slider 26 and push rod 15 are driven to move by the lead screw 13, pushing several transistors toward the first feeding groove, so that the transistors enter the first feeding groove and slide down, thus feeding them.

[0041] In a preferred embodiment, a baffle plate 22 corresponding to the metal frame 4 on the transistor strip 1 is provided at the end of the feeding seat 6. An installation port is provided on the inner side of the baffle plate 22, and a pressure sensor 23 is provided in the installation port.

[0042] After the transistor strip 1 is pushed from the feeding section 24 to the slitting section 25, the metal frame 4 on the transistor strip 1 is stopped and limited by the baffle plate 22, and the metal frame 4 on the transistor strip 1 presses against the pressure sensor 23 to transmit signals. The push rod 15 stops pushing and the slitting begins.
