Abstract
Description
Technical Field
[0001] This utility model relates to the field of bending device technology, specifically to a bending device for MOS device pins. Background Technology
[0002] A MOS device is a device composed of metal electrodes, an oxide insulating layer, and a semiconductor substrate. By changing the gate voltage, the electric field on the semiconductor surface is controlled, thereby regulating the current between the source and drain. When the gate voltage reaches a certain threshold, an inversion layer is formed on the semiconductor surface, allowing current to flow between the source and drain, thus achieving switching control of the current. During the manufacturing process of a MOS device, the pins need to be bent using a bending device.
[0003] A search revealed that Chinese patent application CN201921929807.8 discloses a MOS device pin bending device, comprising a chassis, a pin bending device body fixedly connected to the top of the chassis, a horizontal plate movably connected to the inner wall of the chassis, a fixed plate fixedly connected to the top of the horizontal plate, a MOS device body movably connected to the top of the fixed plate, and pin bodies fixedly connected to both sides of the MOS device body.

[0004] In the aforementioned prior art, positioning rods on both sides are manually pushed, which in turn move sliding blocks and fixing sleeves to clamp different types of MOS devices. This clamping method can only clamp different types of MOS devices. However, as the MOS device model changes, the pin positions and bend positions also change. The aforementioned prior art is not convenient to adjust according to the pin positions and bend positions of different types of MOS devices, thus reducing its applicability. Utility Model Content

Detailed Implementation
[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0028] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a MOS device pin bending device, including a base 1, a placement platform 11 fixedly connected to the upper middle of the base 1, a control box 12 fixedly connected to the outer side of one end of the base 1, a top plate 13 fixedly connected to the outer side of the upper side of the base 1, and an adjustment component provided in the middle of the placement platform 11. The adjustment component includes a motor 21 fixedly connected to one side of the placement platform 11, and a threaded rod 22 fixedly connected through the output shaft of the motor 21 through the placement platform 11. The end of the threaded rod 22 away from the motor 21 is rotatably connected to the placement platform 11, and threaded plates 23 are threadedly engaged on the outer sides of both ends of the threaded rod 22. A transmission plate 24 is fixedly connected to the end of the threaded plate 23 away from the threaded rod 22. The device can clamp and fix different types of MOS devices by adjusting the component, thereby improving the clamping applicability range and bending efficiency.
[0029] It should be noted that the threaded rod 22 is a bidirectional threaded rod, and two sets of threaded plates 23 are engaged with the outer threads at both ends of the threaded rod 22, and the two sets of threaded plates 23 move in opposite directions.
[0030] like Figure 4 As shown, a clamping plate 25 is fixedly connected to one end of the transmission plate 24 away from the threaded plate 23, and a first rubber pad 26 is fixedly connected to one side of the two sets of clamping plates 25 facing each other. The transmission plate 24 drives the clamping plates 25 and the first rubber pad 26 to move, so that the clamping plates 25 and the first rubber pad 26 can squeeze and restrict the two sides of the MOS device.
[0031] like Figure 2 and Figure 4 As shown, a first electric telescopic rod 27 is fixedly connected inside the clamping plate 25, and a first pressure plate 28 is fixedly connected to the upper end of the first electric telescopic rod 27. A second rubber pad 29 is fixedly connected to the lower side of the end of the first pressure plate 28 away from the first electric telescopic rod 27. The first pressure plate 28 and the second rubber pad 29 are moved by the operation of the first electric telescopic rod 27, which facilitates the compression and restriction of the upper side of the MOS device.
[0032] like Figure 2 As shown, a second electric telescopic rod 210 is fixedly connected to the lower side of both ends of the placement platform 11, and a bending plate 211 is fixedly connected to the end of the second electric telescopic rod 210 away from the placement platform 11. The bending plate 211 can be moved and adjusted by the operation of the second electric telescopic rod 210.
[0033] like Figure 1As shown, a double-headed electric telescopic rod 212 is fixedly connected to the middle of the upper side of the top plate 13, and a controller 213 is electrically connected to one side of the double-headed electric telescopic rod 212. The lower end of the controller 213 is fixedly connected to the top plate 13, and a moving plate 214 is fixedly connected to the output shafts at both ends of the double-headed electric telescopic rod 212. The moving plate 214 is moved by the double-headed electric telescopic rod 212 to facilitate the adjustment of the position of the two sets of third electric telescopic rods 217.
[0034] like Figure 1 As shown, the two ends of the movable plate 214 are fixedly connected to limit blocks 215, and a slide rail 216 is sleeved on the outer side of the end of the limit block 215 away from the movable plate 214. The lower end of the slide rail 216 is fixedly connected to the top plate 13. The movement of the movable plate 214 is restricted by the movement of the limit block 215 within the slide rail 216.
[0035] like Figure 3 As shown, a third electric telescopic rod 217 is fixedly connected to the upper side of the movable plate 214. The lower end of the third electric telescopic rod 217 passes through the movable plate 214 and is fixedly connected to a second pressure plate 218. The operation of the third electric telescopic rod 217 drives the second pressure plate 218 to move, thereby allowing the second pressure plate 218 to bend the pins of the MOS device.
[0036] Working principle: When bending the pins of a MOS device, the MOS device is first placed on the bending plates 211 at both ends of the placement platform 11. The position of the bending plates 211 is adjusted according to the model of the MOS device. During adjustment, the second electric telescopic rod 210 is controlled to extend and retract via the control box 12. After the second electric telescopic rod 210 extends and retracts, it drives the bending plates 211 to move and adjust. When the bending plates 211 are adjusted to the appropriate position, the second electric telescopic rod 210 is closed. Then, the motor 21 is started. After the motor 21 starts, the output shaft drives the threaded rod 22 to rotate. After the threaded rod 22 rotates, it engages with the threaded plate 23, causing the threaded plate 23 to drive the transmission plate 24 and clamping plate 25 to move. The movement of the clamping plates 25 on both sides drives the first rubber pad 26 to clamp the placed MOS device. After clamping and fixing, the control box 12 controls the movement of the device. The first electric telescopic rod 27 is activated, which drives the first pressure plate 28 and the second rubber pad 29 to move downwards. This allows the first pressure plate 28 and the second rubber pad 29 to clamp and restrict the MOS device for a second time. Then, the controller 213 controls the operation of the double-headed electric telescopic rod 212. After the double-headed electric telescopic rod 212 is in operation, its output shaft pushes the moving plate 214 to move. The moving plate 214, through the limit block 215 and the slide rail 216, drives the third electric telescopic rod 217 and the second pressure plate 218 to move and adjust. When the second pressure plate 218 is adjusted to the appropriate position, the double-headed electric telescopic rod 212 is closed, and then the third electric telescopic rod 217 is activated to push the second pressure plate 218 downwards. This allows the second pressure plate 218 to squeeze the pins of the clamped MOS device, causing it to bend under the positioning of the bending plate 211.
[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
