[0002] A chip, also known as a microcircuit, a microchip, or an integrated circuit, refers to a silicon wafer containing an integrated circuit. It is very small in size and is often part of a computer or other electronic device. In electronics, it is a way to miniaturize a circuit and is usually manufactured on the surface of a semiconductor wafer. A chip inspection jig is used to inspect chips and mainly serves as a tool to assist in controlling the position or movement.
[0003] In the prior art, there are still certain drawbacks in the use of chip inspection jigs. Traditional chip inspection jigs usually only have one inspection station and can only position one chip at a time, resulting in a slow chip inspection rate. Moreover, when the chip is placed in the jig, it is not easy to take it out, causing inconvenience in inspection. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: A chip inspection jig, including a chip detection jig seat body. On both sides above the chip detection jig seat body, there are fixed sliding grooves. Inside the chip detection jig seat body, there is a double-station chip placement table. On both sides of the double-station chip placement table, there are fixed sliding blocks. At both ends inside the double-station chip placement table, there are respectively a first chip inspection cavity and a second chip detection cavity. At both ends of the double-station chip placement table, there are operating handholds. In the middle position above the chip detection jig seat body, there is a movable cover plate. In the middle position inside the movable cover plate, there is a chip positioning pressing block. At both ends of the bottom of the chip detection jig seat body, there are respectively a left support plate and a right support plate. At the four corners of the bottom of the chip detection jig seat body, there are second fixing screws.
[0006] In a further embodiment, both sides of the double-station chip placement table are slidably connected to the chip detection jig seat body through fixed sliding blocks and fixed sliding grooves, and one side of the movable cover plate is hingedly connected to the fixed sliding groove through a fixed hinge.
[0007] In a further embodiment, the other side of the movable cover plate is clamped and fixed to the fixed sliding groove through a fixed locking hook and a fixed locking rod, and there are anti-slip ridges on the top of the fixed locking hook.
[0008] In a further embodiment, wear-resistant pads and fixing springs are respectively arranged on both sides of the surface of the fixed sliding groove. The lower end of the fixing spring is connected to the fixed sliding groove by welding, and the upper end of the fixing spring is connected to the movable cover plate by embedding.
[0009] In a further embodiment, both the first chip inspection cavity and the second chip detection cavity are fixedly connected to the double-station chip placement table by first fixing screws, and the bottoms of the first chip inspection cavity and the second chip detection cavity are both of a hollow structure.
[0010] In a further embodiment, triangular reinforcement pieces are arranged on the bottom surfaces of both the left support plate and the right support plate. Both the left support plate and the right support plate are connected to the chip detection jig body by plugging and fixing, and the bottom surface of the double-station chip placement table is slidably connected to both the left support plate and the right support plate.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] In this utility model, a first chip inspection cavity and a second chip detection cavity are respectively arranged at both ends inside the double-station chip placement table. The two chip detection cavities are assembled together, and two chips can be stored simultaneously, enabling the two chips to be inspected alternately, thereby achieving the effect of cyclic picking and placing. While one chip is being inspected, the other un-inspected chip can be loaded, which can save time, reserve more operation time, and improve the chip inspection rate. Moreover, the bottom of the chip inspection cavity is of a hollow structure. When the chip inspection cavity is translated to the position of the support plate, the inspected chip inside can be jacked up through the hollow position, separating the chip from the chip inspection cavity and facilitating the removal of the chip.
