Description

Technical Field

[0001] The present invention relates to the technical field of electrical component manufacturing, in particular to a pin forming device for an integrated circuit package. Background Art

[0002] The integrated circuit package is a common electronic component used in aircraft flight control computers. Due to the vibrations generated during flight, to prevent the component's internal circuitry from shorting, the active portion of the component is encapsulated in a single piece of packaging material, leaving only three pins for input and output. A 3.2mm diameter through-hole is provided in the package body for mounting the IC on the circuit board. The three pins are made of silver-plated copper, 0.6mm thick, 1mm wide (2mm wide at the base, 3.5mm long), and 20mm long, and are inserted into corresponding sockets on the circuit board. Because the mounting position and form of the IC package vary on different circuit boards, in mass production, the three pins are machined into a "-" shape with a length of 20mm. These pins can be trimmed or bent to fit the circuit board, depending on the specific circuit board.

[0003] In the prior art, the work of bending the pins of an integrated circuit package into an L-shape is done manually by a skilled worker using wire bending pliers. However, it is difficult to precisely control the bending angle of the pins using manual bending, which affects the subsequent use of the integrated circuit package. Summary of the Invention

[0004] The object of the present invention is to provide an integrated circuit package pin forming device to solve the problems raised in the above background technology.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] A pin forming device for an integrated circuit package includes a mounting mechanism for mounting pins; a bending mechanism connected to the mounting mechanism, the bending mechanism including a circularly rotatable angle positioning component and a bending component for positioning and bending the pin according to the required bending angle; an angle scale connected to the mounting mechanism for cooperating with the bending mechanism to accurately position and bend the pin according to the required bending angle.

[0007] Preferably, the mounting mechanism includes a box body, a bending column connected to the top of the box body, and two position-limiting shielding components.

[0008] Preferably, a position locking component is connected to the angle positioning component.

[0009] Preferably, a manual component is connected to the upper portion of the bending component.

[0010] Preferably, the mounting mechanism is connected to a clamping mechanism, which includes a roller connected to the bottom of the bending component, a guide component connected inside the mounting mechanism, a lifting component slidably connected to the guide component, and two clamping components that can approach or move away from each other.

[0011] Preferably, an elastic component is sleeved on the outer side of the guide component, and the elastic component is located at the bottom of the lifting component.

[0012] Preferably, the top of the lifting component is connected to a pushing component, the bottom ends of the two clamping components are connected to connecting components, and the two connecting components are inserted into the pushing component.

[0013] Preferably, the inclined surfaces on both sides of the inner wall of the pushing component are in contact with the inclined surfaces on the two connecting components respectively.

[0014] The beneficial effects of the present invention are:

[0015] When in use, push the angle positioning component to move in a circle, and combine it with the angle scale line to perform precise angle positioning, and fix the angle positioning component to the top of the box body through the position locking component. Manually drive the manual component to drive the bending component to move in a circle, push the pin through the bending component, and bend the pin through the bending column until the pin contacts one side of the angle positioning component, thereby achieving precise angle bending of the pin to facilitate the subsequent use of the pin.

[0016] When pushing the bending component, the roller moves to the top of the lifting component through the inclined surface on the lifting component, causing the lifting component to move downward on the guide component and squeeze the elastic component, thereby driving the pushing component to move downward, and the pushing component drives the two connecting components to approach each other, thereby driving the two clamping components to clamp the pins, avoiding pin displacement due to shaking, so as to facilitate the bending operation of the pins.

[0025] This device can be used to bend the pins of integrated circuit packages at precise angles, and can also be used to bend other parts.

[0026] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, an integrated circuit package pin forming device comprises a mounting mechanism 1 for mounting a pin 5;

[0028] The mounting mechanism 1 includes a box body 11, a bending column 13 connected to the top of the box body 11, and two position-limiting shielding components 12;

[0029] The position-limiting shielding component 12 may be in the shape of a plate or a strip;

[0030] In this embodiment, the position-limiting shielding member 12 is in a strip shape. When in use, the pin 5 is placed between the two position-limiting shielding members 12 to position the pin 5.

[0031] like Figure 1 and Figure 2 As shown, the bending mechanism 2 is connected to the mounting mechanism 1. The bending mechanism 2 includes a circularly rotatable angle positioning component 21 and a bending component 23, which are used to position and bend the pin 5 according to the required bending angle;

[0032] The angle positioning component 21 is connected to a position locking component 22;

[0033] The upper portion of the bending component 23 is connected to a manual component 24;

[0034] The position locking component 22 may be a bolt or other component with a position locking function, and the manual component 24 may be a handle or other component with a manual driving function;

[0035] Angle scale 3 is connected to the mounting mechanism 1 and is used to cooperate with the bending mechanism 2 to accurately position and bend the pin 5 according to the required bending angle;

[0036] The top of the box body 11 is provided with a first limiting groove 14 and a second limiting groove 15. The angle positioning component 21 and the bending component 23 are respectively limited and slid inside the first limiting groove 14 and the second limiting groove 15. The angle scale line 3 is provided at the top edge of the box body 11.

[0037] In this embodiment, the position locking component 22 is a bolt and the manual component 24 is a handle. When in use, the angle positioning component 21 is pushed to move in a circular motion, and precise angle positioning is performed in combination with the angle scale line 3. The angle positioning component 21 is fixed to the top of the box body 11 through the position locking component 22. The manual component 24 is manually driven to drive the bending component 23 to move in a circular motion, and the pin 5 is pushed through the bending component 23, and the pin 5 is bent through the bending column 13 until the pin 5 contacts one side of the angle positioning component 21, thereby achieving precise angle bending of the pin 5 to facilitate the subsequent use of the pin 5.

[0038] like Figure 3 、 Figure 4 and Figure 5 As shown, the mounting mechanism 1 is connected to a clamping mechanism 4, which includes a roller 44 connected to the bottom of the bending member 23, a guide member 41 connected to the mounting mechanism 1, a lifting member 42 slidably connected to the guide member 41, and two clamping members 45 that can move closer to or farther away from each other;

[0039] The outer side of the guide component 41 is sleeved with an elastic component 43, and the elastic component 43 is located at the bottom of the lifting component 42;

[0040] The top of the lifting component 42 is connected to a pushing component 47 , and the bottom ends of the two clamping components 45 are connected to connecting components 46 , and the two connecting components 46 are inserted into the pushing component 47 ;

[0041] The inclined surfaces on both sides of the inner wall of the pushing member 47 are in contact with the inclined surfaces on the two connecting members 46 respectively;

[0042] The guide component 41 is fixed in the box body 11. The side of the lifting component 42 near the roller 44 is inclined. Two through slots are provided at the top of the box body 11 near the position-limiting shielding component 12. Two connecting components 46 pass through the two through slots respectively. The two clamping components 45 are respectively inserted into the inner sides of the two position-limiting shielding components 12 and both contact the top of the box body 11. The inclined surfaces of the two connecting components 46 are in an inverted V shape. The two inclined surfaces inside the pushing component 47 are in an inverted V shape.

[0043] The clamping member 45 may be in the shape of a plate, a block or a strip, the guide member 41 may be in the shape of a quadrangular prism or other polygonal prism, and the elastic member 43 may be a spring, an elastic sheet or other member having an elastic function;

[0044] The lifting member 42 is moved downward on the guide member 41 and squeezes the elastic member 43, thereby driving the pushing member 47 to move downward. The pushing member 47 drives the two connecting members 46 to approach each other, thereby driving the two clamping members 45 to clamp the pin 5 to avoid displacement of the pin 5 due to shaking, so as to facilitate the bending operation of the pin 5. After the bending operation is completed, the bending member 23 is restored to its original position, the roller 44 leaves the lifting member 42, and under the action of the elastic member 43, the lifting member 42 and the pushing member 47 are restored to their original position. At this time, the two connecting members 46 are no longer subjected to force, so the clamping member 45 no longer clamps the pin 5. Then the bent pin 5 can be removed and replaced with the pin 5 to be bent.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components.
