[0002] The existing cell counting plate is manually pushed into the specified position on the slide receiving surface, and the driving motor rotates to drive the motor gear to rotate so that the slide equipped with the rack moves forward into the observation area. After the counting plate observation and photography are completed, the motor reverses to drive the slide back to the initial position, and the counting plate is pulled out, and the whole work is completed.

[0003] For example, the patent document with publication number CN211227156U discloses a cell counting plate, including a box body, a pad is welded at the lower end of the box body, a slot is clamped at the upper end of the pad, a sponge block is arranged in the slot, a placement slot is opened at the upper end of the sponge block, a cell counting plate is placed in the placement slot, a groove is opened at the upper end of the cell counting plate, a cover glass is contacted and connected at the upper end of the cell counting plate, a box cover is hinged at the upper end of the box body, a filter hole is opened at the upper end of the box cover, a mounting seat is bonded at the lower end of the box cover, and a spring is arranged at the lower end of the mounting seat. , the lower end of the spring is fixedly connected with a pressing plate; when working, open the box cover, place the cell counting plate in the placement groove, place the cover glass on the cell counting plate, cover the box cover, the box cover is fixed by the limit hole and the limit pin, the box cover is fixed and presses the sealing pad, so that the inside of the box body is closed, and then the cell counting plate is pulled forward. However, this method of pulling the cell counting plate manually is not only inconvenient, but also has poor stability when pulled by hand, and there is a large shake. After pulling for a while, the focus needs to be adjusted, and the operation is complicated.

[0004] However, the observation effect of the cell counting plate is affected by the focal length between the lens and the counting plate, especially the throughput device with an electric slide. The main factors affecting the focal length of the lens are: the manufacturing accuracy of the slide itself, the assembly accuracy of the slide, the manufacturing accuracy of the slide mounting plate, the assembly accuracy of the slide mounting plate, and the assembly accuracy of the lens; these factors greatly increase the difficulty of parts processing and place high demands on assembly. When these high requirements cannot be met, there are often differences in the observation clarity between different holes on the same counting plate, requiring frequent focusing. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a snap-on clamping cell counting plate automatic throughput device with low processing difficulty and low assembly requirements.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a snap-clamp type cell counting plate automatic throughput device, comprising a sheet-carrying platform, a driving component, a counting plate, a spring hinge, and a moving component; a groove is provided at the center of the top surface of the sheet-carrying platform along the length direction; a counting plate with a thickness less than the depth of the groove is inserted into the inlet of the groove; the moving component is fixed to one half of the spring hinge; a snap with a wedge at the end is fixed to the bottom surface of the other half of the spring hinge; the oblique lower end of the wedge at the end of the snap is arranged toward the middle of the spring hinge; the outer end of the wedge at the end of the snap is placed on the stopper; the stopper is arranged above the counting plate; a clamping hole that is mutually engaged with the snap is provided at the end of the counting plate toward the moving component; and the moving component is driven forward by the driving component.

[0007] By providing a spring hinge and a buckle connected to the bottom of the spring hinge, when the stepping motor drives the counting board forward, the elastic effect of the spring hinge offsets the unstable movement of the moving component caused by poor manufacturing precision, thereby reducing factors affecting the focal length.

[0008] Preferably, side pressure plates are installed on both sides of the inlet of the groove; the side pressure plates are fixed on the top surface of the sheet-carrying platform; and the distance between the adjacent surfaces of the two side pressure plates is smaller than the width of the groove opening. The top of the counting plate is restricted to prevent the counting plate from detaching from the top of the groove.

[0009] Preferably, the stopper spans the groove; and two ends of the stopper are embedded in the gap between the side pressure plate and the sheet-carrying platform.

[0010] Preferably, the driving assembly includes a stepper motor, a motor gear and a rack; the stepper motor is fixed at the bottom of the wafer support platform; the output end of the stepper motor is transmission-connected with an output shaft; the end of the output shaft vertically passes through the wafer support platform and is fixedly sleeved with a motor gear; one side of the motor gear is meshed with the rack; the length direction of the rack is consistent with the length direction of the groove; the side of the rack with teeth faces away from the groove; the back side of the rack is fixedly connected to the moving assembly.

[0011] Preferably, it also includes a linear guide rail; the linear guide rail includes a slide and a slider; the slide is fixed to the sheet-carrying platform; the guide of the slide is parallel to the length direction of the groove; the slider is slidably connected to the slide; the slider is fixedly connected to the moving component.

[0012] Preferably, the moving component includes a moving plate, a semi-cylindrical groove, a cylinder and a connecting boss; the output end of the driving component is fixedly connected to the boss; the moving plate is fixed to the slider at the lower edge facing the boss; a slot arranged up and down is provided on the side wall of the moving plate facing the boss; a clamping column is fixed on the side of the boss facing the moving plate; and the clamping column is embedded in the slot.
