Description

Technical Field

[0001] The utility model relates to the technical field of transistor cutting, and more specifically to a pin cutting device for transistor processing. Background Art

[0002] A transistor, also called a semiconductor transistor or a crystal transistor, is a semiconductor device that controls current. Its main functions are current amplification and switching. A transistor has three electrodes, namely the base (represented by the letter b), the collector (represented by the letter c) and the emitter (represented by the letter e). Depending on the structure, transistors can be divided into two types: NPN and PNP.

[0003] When a general device cuts the pins of a transistor, it first places the transistor with the pins to be cut above the clamping device located inside the groove, and then starts the cylinder to drive the upper clamping plate to descend. When the clamping plate fixes the transistor, the cutting mechanism also descends at the same time, so that the cutting head of the cutting mechanism contacts the pins of the transistor and cuts it. However, during the descent process, since the clamping device at the bottom is achieved through the cooperation between the spring and the arc plate, when the transistor to be cut is thinner, the upper clamping plate will apply force to both sides to the two arc plates at the bottom during the downward pressure. When the spring is subjected to force, one end moves back to the other end, so it needs to be modified and optimized. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 6 As shown, the utility model provides a pin cutting device for transistor processing, comprising a base 1, a cutting seat 2, and a bracket 22; the cutting seat 2 is fixedly arranged above the base 1, and the bracket 22 is fixedly arranged above the cutting seat 2;

[0033] A fixing mechanism, fixedly arranged inside the cutting seat 2;

[0034] The fixing mechanism includes a motor 1 3 fixedly arranged inside the cutting seat 2, a threaded rod 4 is fixedly installed above the transmission shaft of the motor 1 3, a threaded sleeve 1 5 and a threaded sleeve 2 7 are threadedly sleeved above the threaded rod 4, a clamping plate 1 6 is fixedly installed above the threaded sleeve 1 5, and a clamping plate 2 8 is fixedly installed above the threaded sleeve 2 7;

[0035] The threaded sleeve 1 5 is located on the right side of the threaded sleeve 2 7 , a top plate 9 is fixedly installed above the bracket 22 , a cylinder 10 is fixedly installed above the top plate 9 , the cylinder 10 is fixedly installed through the upper and lower sides of the top plate 9 , and a clamping plate 3 11 is fixedly installed below the top plate 9 .

[0036] When the staff needs to cut the pins of the transistor, they first place the transistor with the pins to be cut between the clamping plate 1 6 and the clamping plate 2 8, and then start the motor 1 3. When the motor 1 3 is started, it will drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, since the connection between the threaded sleeve 2 7 and the threaded sleeve 1 5 and the threaded rod 4 is provided with threads, the rotation of the threaded rod 4 will drive the threaded sleeve 1 5 and the threaded sleeve 2 7 to approach each other. When the threaded sleeve 1 5 and the threaded sleeve 2 7 approach each other, they will drive the clamping plate 1 6 and the clamping plate 2 8 to approach each other. As the clamping plate 1 6 and the clamping plate 2 8 approach each other, they will get closer and closer to the transistor in the middle, and then the clamping plate 3 11 will be driven down by starting the cylinder 10.

[0037] By placing the transistor with the pin to be cut between the clamp plate 1 6 and the clamp plate 2 8, and then starting the motor 1 3, the threaded rod 4 will be driven to rotate. As the threaded rod 4 rotates, the threaded sleeve 1 5 and the threaded sleeve 2 7 will be driven to approach each other, and the clamp plate 1 6 and the clamp plate 2 8 will be driven to approach each other. Then, the clamp plate 3 11 will be driven down by starting the cylinder 10. Compared with the traditional device, the device fixes the transistor with the cutting pin through a fixing mechanism, avoiding the influence caused by only fixing with a spring, improving the efficiency of the device in fixing the transistor, and improving the stability when cutting the transistor.

[0038] The device further comprises: an adjusting mechanism, movably arranged above the top plate 9;

[0039] The moving mechanism is fixedly arranged above the adjusting mechanism;

[0040] The moving mechanism includes a motor 16 fixedly arranged above the adjusting mechanism, a gear 17 is fixedly installed above the transmission shaft of the motor 16, a rack 15 is movably installed inside the adjusting mechanism, the rack 15 movably runs through the upper and lower sides of the adjusting mechanism, the gear 17 and the rack 15 are meshed with each other, a connecting rod 20 is fixedly installed on the side of the rack 15, a fixing bar 21 is fixedly installed above the cutting seat 2, the other end of the fixing bar 21 is fixedly connected to the top plate 9, and the connecting rod 20 is movably connected to the fixing bar 21.

[0041] When the staff has finished fixing the transistor, the staff starts the motor 2 16. When the motor 2 16 is started, it will drive the gear 17 to rotate. When the gear 17 rotates, since the gear 17 and the rack 15 are meshed with each other, the rack 15 will move downward as the gear 17 rotates. When the rack 15 moves downward, it will drive the connecting rod 20 to move downward along the fixing bar 21. When the cutting is completed, the staff starts the motor 2 16 to drive the gear 17 to rotate in the opposite direction. When the gear 17 rotates in the opposite direction, it will drive the rack 15 to move upward.

[0042] By starting the motor 2 16, the gear 17 is driven to rotate. As the gear 17 rotates, the rack 15 is driven to move downward. When the rack 15 moves downward, the connecting rod 20 is driven to move downward along the fixed bar 21. At this time, the cutting mechanism will move downward. When the cutting mechanism moves to the pin surface of the transistor, the motor 2 16 can be turned off. Compared with the traditional device, the device can move the cutting mechanism up and down through the moving mechanism to avoid synchronous descent with the clamp plate 3 11, so that the cutting mechanism causes damage to the surface of the cutting seat 2, thereby reducing the service life of the cutting seat 2 and reducing the use cost of the device.

[0043] Among them, the adjustment mechanism includes a movable plate 12 fixedly arranged above the top plate 9, the upper part of the movable plate 12 is fixedly connected to the motor 2 16 of the moving mechanism, the internal movability of the movable plate 12 is connected to the rack 15, the internal thread of the top plate 9 is sleeved with a screw rod 14, one end of the screw rod 14 is fixedly passed through the movable plate 12, and the other end of the screw rod 14 is fixedly installed with a handle 13.

[0044] The cutting mechanism is adjusted so that it can cut pins of transistors with different lengths, thereby improving the efficiency of the cutting mechanism.

[0045] The device also includes: a cutting mechanism, which is fixedly arranged below the rack 15;

[0046] The cutting mechanism includes a motor 3 18 fixedly arranged below the rack 15, and a cutting head 19 is fixedly installed above the transmission shaft of the motor 3 18.

[0047] The pins of the transistors above the clamping plate 1 6 and the clamping plate 2 8 are cut off to facilitate the insertion of new pins.

[0048] There are two groups of adjustment mechanisms, both of which are movably arranged above the top plate 9 and located on both sides of the cylinder 10.

[0049] The two sets of moving mechanisms can be adjusted simultaneously, so that the moving mechanism can drive the cutting mechanism to move.

[0050] There are two groups of moving mechanisms, which are evenly distributed above the two groups of adjusting mechanisms.

[0051] The two groups of cutting mechanisms are moved so that both groups of cutting mechanisms can move.

[0052] There are two groups of cutting mechanisms, which are evenly distributed below the two groups of moving mechanisms.

[0053] The pins of two transistors can be cut at the same time, thereby improving the working efficiency of the device in cutting the transistor pins.

[0054] The cross sections of the first clamping plate 6 and the second clamping plate 8 are arc-shaped, and the curvatures of the first clamping plate 6 and the second clamping plate 8 are the same.

[0055] Similar to the shape of a transistor, it can have a better fixing effect when fixing the transistor.

[0056] The working principle and use process of this utility model:

[0057] When the staff needs to cut the pins of the transistor, they first place the transistor with the pins to be cut between the clamping plate 1 6 and the clamping plate 2 8, and then start the motor 1 3. When the motor 1 3 is started, it will drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, since the connection between the threaded sleeve 2 7 and the threaded sleeve 1 5 and the threaded rod 4 is provided with threads, the rotation of the threaded rod 4 will drive the threaded sleeve 1 5 and the threaded sleeve 2 7 to approach each other. When the threaded sleeve 1 5 and the threaded sleeve 2 7 approach each other, they will drive the clamping plate 1 6 and the clamping plate 2 8 to approach each other. As the clamping plate 1 6 and the clamping plate 2 8 approach each other, they will get closer and closer to the transistor in the middle, and then the clamping plate 3 11 will be driven down by starting the cylinder 10.

[0058] When the staff has finished fixing the transistor, the staff starts the motor 2 16. When the motor 2 16 is started, it will drive the gear 17 to rotate. When the gear 17 rotates, since the gear 17 and the rack 15 are meshed with each other, the rack 15 will move downward as the gear 17 rotates. When the rack 15 moves downward, it will drive the connecting rod 20 to move downward along the fixing bar 21. When the cutting is completed, the staff starts the motor 2 16 to drive the gear 17 to rotate in the opposite direction. When the gear 17 rotates in the opposite direction, it will drive the rack 15 to move upward.
