Description

Technical Field

[0001] The utility model relates to the technical field of medical detection equipment, in particular to a mixing device for a porous plate. Background Art

[0002] In the medical testing instruments of the in vitro diagnostic industry, mixing and centrifugation are basic functions. General models of testing equipment have the mixing function, or are equipped with a special mixing device to perform this process. The general operation is to loosen the clamp mechanism of the device, place the multi-well plate reagent rack containing the reagent samples to be mixed in the corresponding position of the clamp of the mixing device, and after adjusting to the correct position, adjust the clamp mechanism to clamp the multi-well plate reagent rack, and then start the mixing device to mix.

[0003] When the reagent sample is mixed in this way, the operator needs to manually place the multi-well plate reagent rack into the mixing device and manually adjust the position of the clamp, which greatly increases the time of the mixing process, resulting in a long overall sample inspection time and high labor costs.

[0004] In summary, existing medical testing instruments have technical problems of time consumption and high labor costs when performing mixing operations on reagents. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing medical testing instruments have the technical problem of consuming time and high labor cost when performing mixing operation on reagents.

[0006] In order to solve the above problems, the utility model provides a mixing device for a porous plate, comprising a vibration base, a mixing drive component that drives the vibration base to vibrate and mix the reagent, an automatic clamping component that is used to clamp the porous plate reagent rack placed on the vibration base, and a clamping sensing mechanism that is used to sense the position state of the automatic clamping component, which is used to automatically control the mixing drive component to perform a mixing process after sensing that the automatic clamping component clamps the porous plate reagent rack to be mixed.

[0007] Compared with the traditional mixing device, this design optimizes the automatic control design of the device. A special automatic clamping component is set up to cooperate with the clamping sensing mechanism, which can automatically obtain the position of the multi-well plate reagent rack placed on the vibration base of the device. When it is sensed that the automatic clamping component is clamped, the mixing drive component is directly controlled to perform automatic mixing operations. This design can fully adapt to the process requirements of automated continuous testing and save manual operations as much as possible.

[0008] As a preferred solution, the automatic clamping assembly includes an executive motor fixedly mounted on the vibration base, a clamping link mechanism drivingly matched with the output shaft of the executive motor, and a chuck mechanism symmetrically connected to both sides of the clamping link mechanism, through which the two ends of the multi-well plate reagent rack base are clamped and positioned. The structural design of the automatic clamping assembly is optimized in this design, and the clamping link mechanism drives the action of the chuck mechanism through the output motion of the executive motor, and the chuck mechanism directly acts on the two ends of the multi-well plate reagent rack base.

[0009] As a preferred solution, the clamping link mechanism includes a rotatable annular link in the shape of a rotating body, one side of the annular link is matched with the output shaft of the execution motor through the structure of a lever and a block, and the output rotation of the execution motor drives the lever to rotate and toggle the block on the annular link to drive the rotation of the annular link, driving the chuck mechanism connected on both sides to perform the action of releasing the clamp. This design optimizes the structural design of the clamping link mechanism, and the chuck mechanism is connected through the rotatable annular link transmission to ensure the synchronization of the two chuck movements. Specifically, when the annular link is driven to rotate, the block is toggled by the lever to push the annular link.

[0010] The annular connecting rod is also connected to an automatic clamp tightening mechanism, which is used to automatically pull the annular connecting rod to rotate in the clamping direction when the execution motor does not output an action, so that the clamp mechanism remains in a normally closed state. This design provides an optimal clamp control drive control design. The movement output by the execution motor is only used to drive the opening of the clamp. When the driving force is not applied by the motor, the clamp remains clamped and closed under the action of the automatic clamp tightening mechanism, saving the power consumption of the motor-driven clamping. It only needs to output a rotational movement when the clamp is opened, ensuring the reliability of the device.

[0011] As a preferred solution, the clamping sensing mechanism includes a rotary chopper connected to the output shaft of the actuator motor, and a first position optical coupler and a second position optical coupler distributed in a circle on the rotation track of the rotary chopper, which are respectively used to sense the clamping state and the loosening state of the chuck mechanism. This design provides a preferred clamping sensing mechanism design, which realizes sensing through two sets of position optical couplers corresponding to the opening and closing states of the chuck mechanism in conjunction with the rotary chopper. The rotary chopper is connected to the output shaft of the actuator motor, and the two position optical couplers are both located on its rotation track. The optical couplers at the corresponding positions blocked by the rotary chopper are converted into position signals to control the start of the corresponding vibration mixing action.

[0012] As a preferred solution, the vibration base includes an upper vibration plate and a lower mounting plate arranged in parallel at a preset distance, the actuator motor is mounted on the bottom end surface of the lower mounting plate, the first position optical coupler and the second position optical coupler are both mounted on the upper end surface of the lower mounting plate, and the clamping link mechanism and the chuck mechanism are both located between the upper vibration plate and the lower mounting plate. This design optimizes the placement design of each connecting rod and sensor structure in the device, and the vibration base adopts a double-plate design to provide internal structure installation space.

This design optimizes the structural design of the chuck mechanism in the device, and the linearity of the chuck movement direction is ensured by the guide slot, and the end of the guide screw is embedded in the slot to ensure the guiding and limiting effects.

[0014] As a preferred solution, the automatic clamp tightening mechanism includes a lever fixedly connected to the annular connecting rod, and a mounting seat positioned between the upper vibration plate and the lower mounting plate, and a clamping tension spring is connected between the lever and the mounting seat, and the clamping tension spring provides elastic force to maintain the clamping action of the clamp mechanism. The above technical solution is further extended under the above technical ideas, and the tension spring provides continuous tension as the power for the clamp to be normally closed, and the lever is pulled by the lever to drive the annular connecting rod to maintain the movement trend in the direction of closing the clamp.

[0015] As a preferred solution, the mixing drive assembly includes an eccentric vibration motor, which is fixedly mounted on the lower mounting plate, and whose output shaft is against the upper vibration plate through a bearing mechanism, and the annular connecting rod surrounds the outer periphery of the bearing mechanism. The structural design of vibration mixing is optimized, and the vibration action used to drive mixing is output by the eccentric vibration motor.
