Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a servo slide pitch changing device of a pipetting head intelligent production line system. Background Art

[0002] Pipette heads are a type of consumable material that is widely used in the fields of medicine, biology, chemistry, etc. They are used in conjunction with pipette guns to quantitatively measure liquids. At present, pipette heads are molded by injection molding machines. In the process of producing pipette heads by injection molding machines, multiple pipette heads can be molded at one time. The pipette heads produced by injection molding on injection molding machines need to be inspected and can only be put on the market after passing the inspection. With the rapid production of injection molding machines, a mature and fast detection and transportation production line is required to match them. The injection molding machine and the production line with detection and transportation are two independent systems. The fixture that fixes the pipette head on the injection molding machine is generally a circular structure, while the pipette head fixture of the detection and transportation production line is a square structure, and the two cannot be directly connected.

[0003] Therefore, how to provide a variable pitch device that can transform a pipette head fixture with a circular structure layout into a pipette head fixture with a rectangular structure is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0004] In view of this, the present invention provides a servo slide pitch changing device of a pipetting head intelligent production line system, aiming to solve the inconsistency between the tooling and fixture of the pipetting head after it is completed on the injection molding machine and the tooling and fixture on the inspection and transportation production line in the prior art, and to achieve the connection between the injection molding machine and the inspection and transportation production line.

[0007] The beneficial effect of adopting the above technical scheme is: by arranging multiple first pipette head suction heads on the first fixed plate and multiple second pipette head suction heads on the sliding plate, the position of the second pipette head suction heads in the first through hole can be changed under the drive of the telescopic device, thereby achieving a change in the suction cup structure layout formed by multiple first pipette head suction heads and multiple second pipette head suction heads, and realizing the conversion of the circular pipette head with a polygonal structure on the same circle on the injection molding machine into a rectangular structure matching the inspection and transportation on the production line, that is, realizing the conversion of the suction cup from "circle to square" structure. The suction cup with a rectangular structure has higher operating efficiency in the inspection and transportation process than the suction cup with a polygonal structure, and at the same time, the process requirements for the tooling fixture are also reduced.

[0008] Furthermore, the suction cups are provided in plurality, and the plurality of suction cups are arranged at intervals. The production efficiency of the intelligent production line of the pipetting head can be improved by arranging the plurality of suction cups.

[0009] Furthermore, it also includes a sliding component, which is arranged along the telescopic direction of the telescopic device and is arranged between the first fixed plate and the sliding plate to facilitate the movement of the sliding plate along the telescopic direction of the telescopic device.

[0010] Furthermore, the sliding assembly includes a slide rail and a slide groove adapted to the slide rail;

[0012] The slide rail is fixed on the slide plate along the telescopic direction of the telescopic device, and the slide groove is correspondingly arranged on the first fixed plate.

[0013] The beneficial effect of adopting the above technical solution is: through the setting of the sliding component, it can be achieved that when the telescopic device is extended and retracted, the sliding plate can slide in a specific direction, and the sliding is relatively smooth and light, thereby achieving the change in the positions of multiple second pipetting head tips, thereby realizing the rapid conversion of the suction cup structure.

[0014] Furthermore, the first through hole is an elongated hole, and the length direction of the elongated hole is arranged in the same direction as the telescopic direction of the telescopic device.

[0015] Furthermore, the first pipette tip and the second pipette tip both have an air channel, and the air channel is connected to an external air source through a right-angle two-way pipe fixed at the end thereof.

[0016] Furthermore, it also includes a displacement sensor fixed on the first fixed plate, and a baffle used in conjunction with the displacement sensor, and the baffle is fixed on the sliding plate. By setting the displacement sensor, the controllability of the moving distance of the sliding plate relative to the first fixed plate is achieved, thereby realizing the intelligence of the pitch-changing device.

[0017] Furthermore, the telescopic device is a cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
