Description

Technical Field

[0001] The present invention relates to the technical field of chip detection, in particular to a microfluidic chip detector and a method thereof. Background Art

[0002] Microfluidic chip is a scientific technology that manipulates fluids at the micron scale. It is also commonly referred to as a chip laboratory or micro-total analysis system. It integrates basic operating units such as sample preparation, reaction, separation, and detection in the fields of biology, chemistry, and medicine onto a chip of a few square centimeters or even smaller. A controllable fluid runs through the entire system through a microchannel network to achieve various functions of a conventional chemical or biological laboratory. In order to avoid situations that affect chip performance, such as particle contamination, surface scratches, and open short circuits on the wafer surface or circuit structure, a microfluidic chip detector is required to detect it.

[0003] At present, some microfluidic chip detectors can take pictures and detect both the upper and lower surfaces of the microfluidic chip detectors when in use. However, in this process, excess external light is likely to affect the imaging effect, thereby affecting the accuracy of subsequent chip detection. In addition, the camera that can take pictures of the lower surface of the chip in some microfluidic chip detectors currently remains in an upward state when not in operation. Therefore, when some microfluidic chip detectors are idle, dust is easily attached to the surface of the camera facing upward, affecting the effect of subsequent chip detection. Summary of the invention

[0004] The purpose of the present invention is to provide a microfluidic chip detector and a method thereof, which can respectively perform shading treatment on the chips placed on the storage plate and the flip mechanism to reduce the influence of excess external light on the subsequent detection effect. In addition, the detector can adjust the direction of the third camera to ensure the effect of subsequent use of the third camera to detect the lower surface of the microfluidic chip, thereby solving the problem that when some microfluidic chip detectors are currently in use, excess external light is likely to affect the detection accuracy, and the third camera remains in an upward state when idle, which is likely to cause dust adhesion and affect the subsequent detection effect.

[0017] A microfluidic chip detection method, the method is applied to a microfluidic chip detector as claimed in claim 1, the detection method is as follows:

[0018] S1: Place the chip at the center of the storage plate, start the hydraulic rod on one side through the controller, and the push plate on one side drives the suction head on one side to move. During this process, the connecting mechanism, the auxiliary mechanism and the adjustment mechanism cooperate to drive the light shield and the light shield to block the excess light source on the top of the chip, and the first camera detects the upper surface of the chip;

[0019] S2: After the upper surface inspection is completed, the suction head on one side absorbs the chip and moves the chip to the top of the transfer table. Then the position of the chip is determined by the second camera for subsequent use;

[0020] S3: The controller starts and moves the chip toward the direction of the flip mechanism through the cooperation of the conveying rack, the transport plate, the hydraulic cylinder, the suction head and the hydraulic rod on the other side.

[0021] S4: Start the electric push rod through the controller, the U-shaped rod drives the force plate to move, the upper tooth plate moves under force, and the spur gear rotates. At this time, the lower tooth plate drives the shading plate to move above the chip. At the same time, the pressure plate drives the extrusion rod to move, and the air on one side of the air storage box is discharged to the inside of the airbag through the ventilation pipe. The thick plate drives the shading plate to descend, and the shading plate blocks and limits the chip. At this time, the lower surface of the chip can be photographed and detected through the third camera.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] When the present invention is in use, the chips placed on the storage plate and the flip mechanism can be shielded respectively through the cooperation of the adjustment mechanism, the light shield and the light protection plate, as well as the cooperation of the light blocking mechanism, the squeezing mechanism and the ventilation tube, so as to reduce the influence of excess external light on subsequent detection effects. In addition, when the detector is idle, the direction of the third camera can be adjusted to ensure the effect of subsequent use of the third camera to detect the lower surface of the microfluidic chip, which solves the problem that when some current microfluidic chip detectors are in use, excess external light is likely to affect the detection accuracy, and the third camera remains in an upward state when idle, which is likely to cause dust adhesion and affect subsequent detection effects.
