Description

Culture dish conveying mechanism

Technical Field

The utility model relates to a laboratory automation equipment technical field especially relates to a culture dish conveying mechanism.

Background

In biochemical automation equipment, a series of operations of injecting bacteria liquid, coating and culturing a culture dish are required to be completed in the automatic strain culture process.

In the above operation, after the culture dish is lifted, the upper culture dish is clamped, and the lowest culture dish is removed. Another operation is to push out the lowest culture dish of the culture dish stack by a push-out mode, and send the culture dish stack to a culture dish rack for subsequent processing.

The operation of moving out the culture dish through the jacking mechanism is complex, and the condition that the culture dish can not be output correctly due to position deviation easily occurs.

And through the output mode of pushing out formula, because the culture dish that piles up is in large quantity on the culture dish stack, when pushing out the culture dish from the position of below, will overcome great resistance, produce great friction when leading to between the culture dish of below and the last culture dish to move, scrape at the bottom of the colored culture dish and the dish lid, perhaps produce the destruction to the subsides mark that sets up on the dish lid.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem, provide a culture dish conveying mechanism, carry out the centre gripping back to penultimate culture dish through the clamping jaw, carry out propelling movement output operation to the culture dish of below, reduce the propelling movement resistance, realize simply sending the dish fast.

The utility model adopts the technical proposal that:

the utility model provides a culture dish conveying mechanism, characterized by, includes culture dish stack, centre gripping unit and conveying unit, the centre gripping unit sets up in culture dish stack below, the centre gripping unit includes two clamping jaws and clamping jaw driver to and the sliding plate that clamping jaw below set up, clamping jaw driver drive clamping jaw folds and carries out the centre gripping to the culture dish, form two arc clamping faces about on the clamping jaw, the radius of going up the clamping face is less than the radius of clamping face down, when going up the ware lid of clamping face centre gripping culture dish, the ware body falls extremely on the sliding plate, conveying unit includes culture dish frame and horizontal driver, culture dish frame and sliding plate height, culture dish whereabouts in the culture dish stack is on the sliding plate, clamping jaw driver drive clamping jaw is to the lid centre gripping of the last second culture dish, horizontal driver drive culture dish frame is to sliding plate direction horizontal motion, outwards releases the sliding plate, and the culture dish on the culture dish frame of below falls into, and the culture dish frame returns, and the sliding plate resets, and the clamping jaw is released after the lid, and the culture dish falls on the culture dish stack.

Furthermore, the culture dish stack comprises a vertical cavity surrounded by at least three elastic retaining columns, and height limiting blocks are arranged on the elastic retaining columns.

Furthermore, the opposite edges of the sliding plate and the culture dish frame are both provided with chamfered edges.

Furthermore, the number of the clamping jaws of the clamping unit is three, the number of the culture dish vacant positions on the culture dish rack of the conveying unit is also three, and each clamping jaw corresponds to one culture dish vacant position.

The utility model has the advantages that:

(1) The culture dish is supported by the clamping mechanism, so that the friction of the culture dish is reduced;

(2) A plurality of culture dishes are processed by the culture dish rack, so that the processing efficiency is improved;

(3) The jacking mechanism is reduced, the structure is simpler, and the error rate is lower.
