[0002] Chip, also known as microcircuit, microchip, integrated circuit, is a way of miniaturizing circuits in electronics, and is often manufactured on the surface of semiconductor wafers. Integrated circuits with circuits manufactured on the surface of semiconductor chips are also called thin-film integrated circuits; another type of thick-film integrated circuit is a miniaturized circuit composed of independent semiconductor devices and passive components integrated into a substrate or circuit board. A chip tray is a packaging tray used by semiconductor packaging and testing companies for their chip packaging and testing. When packaging and testing chips, an anti-static chip tray is used.

[0003] Anti-static chip trays are usually made of carbon fiber or electrified plastic materials. These materials can effectively conduct electricity, quickly disperse and dissipate static electricity, avoid static electricity accumulation, and make the tray have anti-static function. In the process of storing chips on the tray, the chip is placed in the inner cavity of the groove by slotting. There is usually a semicircular groove next to the groove, which is convenient for users to press the chip and take it out. Through the semicircular groove, the user presses the chip with his fingers. The chip is a precision device. When the finger is in the process of pressing the chip, the finger loses contact with the chip, causing part of the chip to fall on the inner wall of the groove, which can easily cause damage to the integrated circuit inside the chip, resulting in a decrease in the qualified rate of the chip, which is not convenient for increasing the contact area between the user's hand and the chip. Utility Model Content

By providing the rotating shaft 11, the friction between the gear 304 and the rotating rod 303 can be reduced, so that the gear 304 can rotate more smoothly and the working stability of the gear 304 is increased;

[0031] Working principle: The tray body 1 is made of carbon fiber, which can effectively conduct electricity, quickly disperse and dissipate static electricity, avoid the accumulation of static electricity, and make the tray body 1 have an anti-static function to prevent static electricity on the tray body 1 from damaging the chip. When the user takes out the chip, press the second tooth plate 306 downward, and the meshing of the gear 304 and the second tooth plate 306, and the meshing of the gear 304 and the first tooth plate 305 can drive the placement plate 301 to move upward, so that the chip moves out of the inner cavity of the placement slot 2, increasing the contact area between the user's hand and the chip, making it convenient for the user to take out the chip. In the process of the placement plate 301 moving upward, the spring 307 will be stretched. After the user takes out the chip, the first tooth plate 305 is driven to move downward under the reaction force of the spring 307 to achieve the reset of the placement plate 301 and the second gear 304.
