Technical Field
The invention relates to the technical field of medical equipment, in particular to a reaction cup conveying device applied to a washing area on a full-automatic luminescence tester.
Background
The washing area on the full-automatic luminescence tester plays a role in cleaning the reaction cup, a groove is formed in the side wall of the reaction cup, a hook is arranged on the back face of the conveying rack, a latch is arranged on the front face of the conveying rack, and the driving motor drives the conveying rack to move through a gear, so that the reaction cup is driven to move in a directional mode in the reaction cup track.
The conventional power supply of the movement of the reaction cup can be realized by a group of motors because the transmission racks are longer and the movement resistance of the reaction cup is smaller. The drive gear is usually installed in the tip of conveying rack, and the other positions of conveying rack also need the gear to compress tightly to the reaction cup direction, prevent that recess on the reaction cup lateral wall from being connected unstably with the couple on the conveying rack, cause the slip phenomenon. In the prior art, a gear playing a role in compaction is usually fixed on a bottom plate by using an eccentric shaft, and the adjustment of the compaction degree of a transmission rack by using the eccentric shaft is realized by using the compaction gear, but the mode has the following defects: 1. the rotation angle of the eccentric wheel needs to be adjusted for a plurality of times by workers, and even after the adjustment is finished, the difference of each machine is large. 2. After long-time use, the eccentric wheel can loosen and rotate a tiny angle, so that the pressing gear is not pressed tightly to the conveying rack, and the hook on the conveying rack can not hook the notch on the reaction cup, so that the test flow fails. 3. Due to the reasons of program errors, improper operation of operators and the like, when the cup clamping condition occurs in the washing area, the driven gear eccentric shaft is easy to rotate, so that the pressing gear cannot press the conveying rack according to the set force, and the test flow fails. 4. When equipment is maintained and adjusted, a worker mistakenly touches the eccentric wheel to slightly rotate, and the pressing gear can not press the conveying rack according to the requirement, so that the follow-up test flow fails.

The straight line where the pressing gear and the driving gear are located is parallel to the conveying rack. The design standardizes the parts and is convenient for unified management.
The device is characterized in that at least 2 spring mounting holes are formed in the plane, corresponding to the vertical plate of the supporting seat, of the ejector rod, a U-shaped groove is formed in the plane, corresponding to the top plate of the supporting seat, of the ejector rod, and the opening of the U-shaped groove points to the conveying rack. The spring mounting hole plays certain fixed action to the spring, prevents that the spring from deviating, and the U groove of going plays spacing effect to the spring in spring axis direction, prevents that the spring from stretching completely, and the interval between ejector pin and the supporting seat riser is greater than the length of spring and causes the phenomenon that the spring drops, the supporting seat roof corresponds the U-shaped recess and is equipped with the cylinder arch, and this arch cooperates the U groove of going to realize above-mentioned function.
The invention has the advantages and positive effects that: due to the adoption of the technical scheme, the compressing effect of the compressing gear on the transmission rack is good, and the compressing device has the advantages of being simple in structure and high in reliability.
