A chip detection device according to claim 8, characterized in that: Each opening and closing assembly (33) comprises a movable frame (331), a movable rod (332), a material discharge block (333) and a return spring (334); the movable frame (331) is slidably arranged in the installation box (31), the movable frame (331) is sleeved on the outside of the material discharge cam (325), one end of the movable rod (332) is fixedly connected to the movable frame (331), the other end of the movable rod (332) passes through the installation box (31) and extends into the installation frame (1), the material discharge block (333) is fixedly connected to the movable rod (332), the material discharge block (333) is adapted to the material discharge plate (44), one end of the return spring (334) is fixedly connected to the material discharge block (333), and the other end of the return spring (334) is fixedly connected to the installation frame (1).

10. A chip detection method, using the chip detection device according to any one of claims 1 to 9, characterized in that: The specific steps include: S1. The chip to be tested is fixed to the conveyor belt (2) through the limiting mechanism (4), and the limiting plate (43) fixes the chip from both sides under the action of the limiting spring (45); S2, turning on the driving motor (63) through the control panel, the driving motor (63) works to drive the active roller (61) to rotate, the active roller (61) rotates through the conveyor belt (2) to drive the friction roller (542) and the driven roller (62) to rotate together, and the conveyor belt (2) moves to send the chip to be tested to the testing unit (5); S3, the friction roller (542) rotates to drive the transmission shaft (541) and the crankshaft (552) to rotate together, and the crankshaft (552) rotates to drive the connecting rod (554) to reciprocate in the vertical direction through the rocker (553). When the connecting rod (554) moves to the lowest point, the detection probe (53) contacts the chip and cooperates with the detector (52) to detect the chip. After the detection is completed, the drive motor (63) continues to work, and the connecting rod (554) moves upward to drive the detection probe (53) to separate from the chip, and the chip continues to move along with the conveyor belt (2); S4, when the chip to be tested moves to the position directly below the testing probe (53), the driving motor (63) stops rotating, and the testing instrument (52) tests the chip. At the same time, the new chip is fixed to the conveyor belt (2) through the limiting mechanism (4); S5, the driven roller (62) rotates through the driving shaft (321) to drive the second bevel gear (324) to rotate together, the second bevel gear (324) rotates through meshing to drive the first bevel gear (323), the driving rod (322) and the material discharge cam (325) to rotate together, the material discharge cam (325) rotates through the movable frame (331) and the movable rod (332) to drive the material discharge block (333) to reciprocate on the horizontal plane; S6. When the chip is sent to the other end of the installation frame (1) along the conveyor belt (2), the discharge plate (44) and the discharge block (333) slide to the discharge block (333), and the discharge block (333) drives the discharge plate to move under the action of the movable frame (331) and the movable rod (332). The movement of the discharge plate (44) drives the limit plate (43) to move through the limit rod (42), and the limit plate (43) loses its limit effect on the chip, and the chip slides off the conveyor belt (2).
