The invention discloses a disk body separation mechanism. The disk body separation mechanism is used for separating stacked disk bodies. The disk body separation mechanism comprises a rack, a materialrack, a clamping assembly and a lifting assembly. The material rack is provided with a material stacking area for containing disk bodies. The clamping assembly comprises a driving motor mounted on the rack, two rotary shafts arranged oppositely, cams mounted on the two rotary shafts correspondingly and clamping blocks connected with the cams. The driving motor drives the rotary shafts to rotate.The rotary shafts drive the cams to rotate so as to drive the clamping blocks on the two opposite sides of a separation area to do telescopic motion relative to the separation area to clamp and release the disk bodies. The lifting assembly controls the clamping assembly and the material rack to move relatively. Compared with the prior art, the disk body separation mechanism has the advantages thatthe cams are matched with the lifting assembly to separate the disk bodies, and the occupied space of the disk body separation mechanism is effectively reduced; the disk body separation mechanism iseasy to control, stable in clamping and not prone to misoperation. The invention further disk a feeding device comprising the disk body separation mechanism.

The invention discloses an experimental pipette support and an experimental method, which belong to the field of experimental appliances, and include a support seat, on which several jacks for inserting pipettes are arranged, and the several The axes of the jacks intersect each other below the support base, and the upper side of the support base is an arc surface whose height gradually decreases from the middle to both sides. The mixing container is placed under the support base, and the pipettes on the support base are sequentially controlled to drip, so that the liquids of different components can be dropped into the same mixing container, without repeatedly moving the pipettes from The pipette holder can be removed from the pipette stand, and the operation is convenient, which solves the problems in the prior art that the operation is complicated and easy to cause operation errors in the experiment of mixing liquids.

A multifunctional intelligent cleaning range hood comprises a shell and an impeller installed in a volute; the shell is divided into a cavity A, a cavity B and a rear cavity; the portion, located in the cavity A, of a middle partition plate is provided with a motor installing hole and a heat dissipating hole; an output shaft of a motor is sequentially provided with a belt pulley A and a blade fromfront to back; a lower shell is rectangular as a whole, and an induction switch is installed in a switch installing portion on the front side of the lower shell; the front side of the switch installing portion is provided with an air outlet; an air inlet is formed above the air outlet; a lighting lamp is installed on the front portion of the lower surface of the lower shell; the rear side of thelower surface of the lower shell is provided with an oil collecting groove; the lower shell communicates with a cavity 2, and a filtering plate is installed in the cavity 2; and a cleaning device is arranged in the volute. According to the multifunctional intelligent cleaning range hood, the counter-acting force of air flow acts on a pressure sensor so that the operation of range hood starting, shutdown and cleaning time and lighting brightness adjusting can be achieved, the function of a non-contact type switch is achieved, and using is safe and hygienic.

The invention discloses a part angle alignment method and a clamp thereof. The method comprises the steps that a process alignment block is firstly manufactured according to the structure of a part, a process alignment hole and mounting holes are machined in the process alignment block, and the process alignment hole or an angular straightening face is machined at the zero-degree position of the clamp; then the clamp is mounted on a machine tool, the process alignment hole or the angular straightening face on the clamp is aligned, the zero-degree angular position is set, and the clamp is pressed; the part is mounted on the clamp and pressed; then the process alignment block is mounted on the part through the process alignment hole and the mounting holes in the process alignment block; finally, a dial indicator is used for metering to straighten the angular straightening face on the clamp and align the alignment hole in the clamp to determine the zero-degree position, the process hole in the part or the process alignment hole in the process alignment block is aligned, the zero-degree angular position of the part is determined, and the zero-degree position of the machine tool is determined. The method is simple in operation process, reasonable in step and accurate in alignment, and by directly aligning an angular alignment locating hole in a locating block, the method is convenient to use and suitable for machining of batched parts.
