[0035] refer to Figures 1 to 4 This application provides at least one chip pin straightening device, which can reduce the requirements for operators and improve the efficiency and accuracy of maintenance.
[0036] Specifically, the chip pin straightening device includes a base platform 1, a fixed mold 2, a movable mold 3, and a rotating assembly. The fixed mold 2 is fixedly mounted on the base platform 1 and has a first hole 2.1 through its thickness corresponding to the chip pin, for the pin to pass through. The movable mold 3 is rotatably mounted on the base platform 1 and located on one side of the fixed mold 2 in the thickness direction. The movable mold 3 (the side facing the fixed mold 2) has a second hole 3.1 corresponding to the first hole 2.1, for the pin end to be inserted. The rotating assembly is mounted on the base platform 1 and connected to the movable mold 3. The rotating assembly acts on the movable mold 3 to rotate relative to the fixed mold 2 along a set trajectory. During the chip pin alignment process, the chip to be aligned is first placed on the fixed mold 2, and the chip pins are sequentially passed through the first hole 2.1 and the second hole 3.1. Then, the rotating component is controlled to drive the movable mold 3, causing the movable mold 3 to rotate relative to the fixed mold 2 along a set trajectory. When the movable mold 3 rotates, it can apply a steering force to the chip pins, thereby returning the chip pins to the correct orientation. In this paper, the set trajectory can be a circular trajectory around the axis of the fixed mold 2.
[0037] Optionally, both the fixed mold 2 and the movable mold 3 can be plate-shaped structures. This arrangement simplifies the construction of the fixed mold 2 and the movable mold 3, reduces processing and production costs, and facilitates the design of compact equipment. It should be understood that, in specific implementations, in order to allow the chip pins to pass through the first hole 2.1, the thickness of the fixed mold 2 can be less than the length of the chip pins.
[0038] Optionally, the fixed mold 2 and the movable mold 3 are fitted together. Specifically, the fixed mold 2 has opposing first and second surfaces along its thickness direction, and the movable mold 3 has opposing third and fourth surfaces along its thickness direction, wherein the third surface faces and is fitted together with the second surface. This arrangement ensures that the force applied to the chip pins by the movable mold 3 during rotation is more uniform and precise, thereby improving the accuracy of pin alignment and avoiding unnecessary deformation or damage to the pins during alignment.
[0039] Optionally, the fixed mold 2 and the movable mold 3 are arranged vertically opposite each other. Specifically, the first hole 2.1 and the second hole 3.1 can be arranged vertically, meaning the axial direction of the first hole 2.1 and the second hole 3.1 is aligned with the vertical direction. When installing the chip, the chip's pins can pass through the first hole 2.1 and the second hole 3.1 sequentially under the influence of gravity. This reduces the need for manual adjustments, improves work efficiency, and lowers the difficulty of operation.
[0040] Optionally, the base platform 1 is provided with multiple pins 1.1, which are vertically arranged. The fixed mold 2 is fixed to the top of the pins 1.1 by screws 2.2, and the movable mold 3 is located between the pins 1.1. Specifically, multiple pins 1.1 are arranged vertically on the upper surface of the base platform 1. When the fixed mold 2 is located at the top of the pins 1.1, the screws 2.2 are screwed into the pins 1.1 through the through holes of the fixed mold 2, thus installing the fixed mold 2 at the top of the pins 1.1. At this time, there is a gap between the bottom surface of the fixed mold 2 and the upper surface of the base platform 1, and the movable mold 3 can be located within this gap to achieve a vertically opposite arrangement of the fixed mold 2 and the movable mold 3. In this embodiment, there are four pins 1.1, which correspond to the four corner positions of the fixed mold 2.
[0041] Optionally, the pin 1.1 passes through the through hole of the movable mold 3, and there is a gap between the pin 1.1 and the movable mold 3. Specifically, the diameter of the through hole of the movable mold 3 is larger than the diameter of the pin 1.1. When the pin 1.1 passes through the through hole of the movable mold 3, there is a gap between the pin 1.1 and the inner wall of the through hole of the movable mold 3. This gap allows the movable mold 3 to move relative to the fixed mold 2, thereby limiting the rotation radius of the movable mold 3. It should be understood that the larger the gap between the pin 1.1 and the inner wall of the through hole, the larger the rotation radius of the movable mold 3 relative to the fixed mold 2.
[0042] Optionally, there is a gap between the movable mold 3 and the base platform 1. In a specific configuration, the rotating component can be installed between the movable mold 3 and the base platform 1, and the rotating component can be connected to the axis of the movable mold 3. This facilitates more even force distribution on the movable mold 3, which helps to improve the stability of the movable mold 3 during rotation and reduces the risk of structural damage.
[0043] Optionally, the pin 1.1 has an enlarged diameter portion for supporting the movable mold 3 and creating a gap between it and the base platform 1. Specifically, the pin 1.1 is divided into two sections from top to bottom, which are referred to as the first section and the second section for ease of description. The diameter of the second section is larger than that of the first section, and the diameter of the second section is also larger than the diameter of the through hole of the movable mold 3. When the first section passes through the through hole of the movable mold 3, the top end of the second section can be supported on the bottom surface of the movable mold 3, thus creating a gap between the movable mold 3 and the base platform 1.
[0044] Optionally, a pad 1.2 is provided between the expanded diameter portion of the pin 1.1 and the movable mold 3. The pad 1.2 is used to reduce the friction between the pin 1.1 and the movable mold 3. For example, the pad 1.2 can be a nylon pad 1.2, a rubber pad 1.2, or a polyethylene pad 1.2, etc.
[0045] Optionally, the rotating assembly includes a rocker arm 4 and a sliding block 5. The rocker arm 4 is mounted on the base platform 1 and can swing 360° relative to the base platform. The sliding block 5 is movably mounted on the base platform 1 and connected between the rocker arm 4 and the movable mold 3. The sliding block 5 can drive the movable mold 3 to rotate when the rocker arm 4 swings. In actual use, the operator can operate the rocker arm 4 to swing 360°. When the rocker arm 4 swings, it can drive the sliding block 5 to move synchronously. When the sliding block 5 moves synchronously with the rocker arm 4, it can also drive the movable mold 3 to rotate.
[0046] Optionally, the rocker arm 4 passes through the base platform 1. The rocker arm 4 is equipped with a first hinge ball 4.1 and a second hinge ball 4.2, which are located on the upper and lower sides of the base platform 1, respectively. The rocker arm 4 is connected to the sliding stroke block 5 through the first hinge ball 4.1 and to the base platform 1 through the second hinge ball 4.2. Since the rocker arm 4 is connected to the sliding stroke block 5 through the first hinge ball 4.1, the angle between the rocker arm 4 and the sliding stroke block 5 can change in real time when the rocker arm 4 swings, ensuring that the rocker arm 4 can swing stably. Since the rocker arm 4 is connected to the base platform 1 through the second hinge ball 4.2, when the rocker arm 4 is subjected to radial thrust, the second hinge ball 4.2 can rotate relative to the base platform 1, allowing the rocker arm 4 to swing 360° relative to the base platform.
[0047] Optionally, the sliding stroke block 5 is located below the movable mold 3 and is spaced apart from the movable mold 3, and the sliding stroke block 5 and the movable mold 3 are connected by a shaft 6. Of course, in other possible embodiments, the height position of the movable mold 3 can also be adjusted so that the sliding stroke block 5 and the movable mold 3 can be directly connected, which can make the structure more compact.
[0048] Optionally, a limiting mechanism is provided between the sliding stroke block 5 and the base platform 1 to limit the range of motion of the sliding stroke block 5. For example, the limiting mechanism includes a limiting slot 5.1 and a limiting post 1.3. One of the limiting slot 5.1 and the limiting post 1.3 is provided on the sliding stroke block 5, and the other is provided on the base platform 1. The limiting slot 5.1 and the limiting post 1.3 cooperate with each other to limit the range of motion of the sliding stroke block 5, thereby preventing the chip pins from being damaged due to excessive rotation radius of the movable mold 3.
[0049] The chip pin straightening device of this application includes a fixed mold 2 and a movable mold 3 arranged opposite to each other. The fixed mold 2 has a first hole 2.1 that penetrates its thickness and corresponds to the chip pin. The movable mold 3 has a second hole 3.1 corresponding to the first hole 2.1 and can rotate relative to the fixed mold 2 along a set trajectory. During the chip pin straightening process, the chip pins pass through the first hole 2.1 and the second hole 3.1 in sequence. By controlling the movable mold 3 to rotate along the set trajectory, a directional force can be applied to the chip pins, thereby returning the chip pins to the correct direction. Therefore, using this device to straighten chip pins can reduce the requirements for operators and improve the efficiency and accuracy of maintenance.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this specification should be included within the protection scope of this application.
