Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the invention.
As shown in fig. 1 to 13, an integrated circuit package pin forming device for multi-station processing includes a lower bending die 1 for placing a package, an upper bending die 2 for bending a package pin, and a guide assembly 3 connected between the upper bending die 2 and the lower bending die 1, wherein the upper bending die 2 slides along the guide assembly 3, the upper bending die 2 corresponds to the lower bending die 1 and is formed with a bending cavity 4, and a pressing cover 23 is arranged on an upper pressing base 20. The guide assemblies 3 are two groups and are respectively positioned on two sides of the lower bending die 1 and the upper bending die 2, and the upper bending die 2 can slide up and down conveniently through the guide assemblies 3. Along with the continuous downward movement of the upper bending die 2, the bending knife edge 22 of the upper bending die 2 and the bending knife edge 22 of the lower bending die 1 jointly act to complete the bending and forming work of the integrated circuit package part pins.
The upper bending die 2 comprises an upper pressing base 20, a plurality of groups of elastic pressing assemblies 21 arranged in the upper pressing base 20 and a bending knife edge 22 arranged on the side of the bottom end of the upper pressing base 20, and the bending knife edge 22 corresponds to the bending cavity 4. The elastic pressing components 21 can be one group, two groups or multiple groups, and are installed according to actual use requirements. For example: when the number of the elastic pressing assemblies 21 is three, the three pressing blocks 211 of the device independently press the pins of one group of integrated circuit packaging parts when working, so that the pins of one group or two groups or three groups of integrated circuit packaging parts can be bent at one time, and the situation that only the pins of one group of integrated circuit packaging parts are required to be bent or the pins of two groups of integrated circuit packaging parts are required to be bent in a batch of processing can not be caused.
The elastic pressing component 21 comprises a plug screw 210 and a pressing block 211 which are respectively arranged in a cavity inside the upper pressing seat 20, and a pressure spring 212 arranged between the plug screw 210 and the pressing block 211, wherein the bottom of the pressing block 211 extends out of the bottom surface of the upper pressing seat 20, so that before a bending knife edge 22 part for bending at the lower end surface of the upper bending die 2 contacts with an integrated circuit package pin, the pressing block 211 and the upper end surface of the lower bending die 1 compress the integrated circuit package pin together, along with the continuous downward movement of the upper bending die 2, the bending knife edge 22 of the upper bending die 2 and the bending knife edge 22 of the lower bending die 1 jointly act to complete the bending forming work of the integrated circuit package pin, then the pressure applied on the pressing block is removed, the upper bending die 2 pushes the upper bending die 2 to move upwards along the guide column 30 under the action of the thrust spring 31 to complete the automatic separation of the upper bending die 2 and the lower bending die 1, and the integrated circuit package is manually taken down from the bending cavity 4 between the upper bending die 2 and the lower bending die 1. In addition, the pressing block 211 is adopted to pre-press the pins of the integrated circuit package part to be bent, so that when the pins of the integrated circuit package part are bent under the combined action of the upper bending die 2 and the lower bending die 1, the pressing block 211 can pre-press the pins of the integrated circuit package part, and the situation that the integrated circuit pins are stressed to cause open circuit in the process of pressing down the upper bending die 2 is avoided. Meanwhile, the upper part of the pressing block 211 is provided with a spring and a screw plug 210 which can pre-adjust the pressure applied by the pressing block 211 on the pins of the integrated circuit package, so that the pressure is in the best state when the pressing block 211 presses the pins of the integrated circuit package, the pins of the integrated circuit package cannot be crushed due to too large pressure, and the situation that the pins are stressed to move when the pins of the integrated circuit package are bent under the combined action of the upper bending die 2 and the lower bending die 1 due to too small pressure is avoided. After the pressing block 211 compresses the pins of the integrated circuit package together with the upper end face of the lower bending die 1, when the upper bending die 2 continues to move downwards to bend the pins of the integrated circuit package, the pressing block 211 can slide in the cavity inside the upper bending die 2, so that the pressing block 211 cannot block the downward movement of the upper bending die 2, and can keep the compression state of the pins of the integrated circuit package. When the external force is removed, the pressing block 211 slides to the original position along the cavity inside the upper bending die 2 under the pressure of the pressure spring 212. The initial pressure exerted on the pressing block 211 by the pressure spring 212 can be adjusted by the screw plug 210 at the upper end of the pressure spring 212.
As shown in fig. 5, the pressing block 211 includes a cylinder 2110 having a cylindrical structure and a pressing bar 2111 disposed below the cylinder 2110 and having a rectangular parallelepiped structure, the cylinder 2110 is connected to an end of the pressure spring 212, and a bottom end of the pressing bar 2111 extends out of a bottom surface of the upper pressing seat 20. The cuboid at the lower end of the pressing block 211 can be consistent with the shape of the top end of the lower bending die 1, pins of an integrated circuit package piece are well pressed, and the upper end of the pressing block 211 is a cylinder and is convenient for installing the pressure spring 212.
The lower bending die 1 comprises a positioning seat 10, a limiting assembly 11 arranged on the positioning seat 10 and used for limiting the packaging part, and a boss 12 arranged on the side of the positioning seat 10 and used for placing pins of the packaging part, wherein a bending cavity 4 is arranged on the side of the positioning seat 10, and the limiting assembly 11 and a pressing block 211 correspond to each 3 groups. The limiting assembly 11 comprises a plurality of limiting columns 110 and a plurality of limiting bosses 111 which are respectively arranged on the positioning seat 10, a limiting cavity for limiting the circumferential direction of the packaging part is formed between the adjacent limiting bosses 111, and the limiting columns 110 are matched and connected with through holes in the packaging part. The limiting columns 110 and the limiting bosses 111 are positioning pins, the positions of the integrated circuit packaging parts placed on the lower bending die 1 are determined by inserting the limiting columns 110 installed on the lower bending die 1 into through holes with the diameter of 3.2mm in the integrated circuit packaging parts, after the integrated circuit packaging parts are positioned by the limiting columns 110, the integrated circuit packaging parts can only rotate by taking the limiting columns 110 as circle centers, meanwhile, the circumference of the integrated circuit packaging parts is limited by limiting cavities formed among the limiting bosses 111, so that the integrated circuit packaging parts are limited in a specified area, in addition, when the upper bending die 2 moves downwards to enable pressing blocks 211 to be in contact with pins of the integrated circuit packaging parts, the pins of the integrated circuit packaging parts continuously move downwards to realize a clamping function, the pins of the integrated circuit packaging parts can be bent by continuously moving downwards the subsequent upper bending die 2, a three-way limiting structure is formed, the pins of the integrated circuit packaging parts are bent at the moment, and the size consistency after the pins are bent and formed can be ensured. In addition, the height of the part for limiting the position of the package on the limiting boss 111 is higher than the thickness of the package, that is, the upper end of the limiting column 110 is higher than the upper end of the integrated circuit package, so that the upper bending die 2 is prevented from continuously descending when the upper bending die 2 descends to contact with the top end of the limiting boss 111, and the integrated circuit package is prevented from being crushed when the upper bending die 2 descends. The limiting boss 111 not only limits the rotation of the integrated circuit package, so that the integrated circuit package is limited at a fixed position, and the sizes of the L-shaped pins of the integrated circuit package processed by the device are consistent, but also plays a role in protecting the integrated circuit package from being crushed by the upper bending die 2. The limiting bosses 111 respectively limit the integrated circuit package in the circumferential direction from two sides, and belong to over-positioning, so that processing errors caused by the fact that an operator does not pay attention to the deflection of the integrated circuit package when one limiting boss 111 is adopted can be effectively avoided, and the over-positioning mode can ensure that the integrated circuit package is placed in an allowed range, namely the integrated circuit package is allowed to deflect in a range meeting the use requirements.
The guiding assembly 3 comprises a guiding column 30 arranged between the upper pressing seat 20 and the positioning seat 10 and a thrust spring 31 sleeved on the guiding column 30, wherein one end of the thrust spring 31 is connected with the upper pressing seat 20, and the other end is connected with the positioning seat 10.
