Description

Technical Field

[0001] The invention relates to the technical field of sample tube decapping, and in particular to an automatic sample tube decapping device. Background Art

[0002] The manual or semi-automatic decapping devices currently on the market require operators to perform decapping operations one by one, which increases the labor intensity, especially when processing a large number of samples, the workload of operators will increase significantly. Due to the need to process one by one, the processing speed of manual or semi-automatic decapping devices is relatively slow, which cannot meet the needs of high-throughput experiments and affects the overall work efficiency. Manual operation requires high proficiency and meticulous operation, and is prone to operating errors, resulting in sample contamination or damage, increasing the uncertainty and repetitive work of the experiment. During manual operation, the operator needs to directly contact the sample tube, which poses certain safety hazards, especially when handling toxic, harmful or flammable and explosive samples. The risk is greater. It is difficult for manual or semi-automatic devices to ensure that the strength and angle of each decapping operation are consistent, which may result in incomplete decapping or sample splashing, affecting the accuracy and reliability of the experimental results. Manual or semi-automatic devices can usually only handle sample tubes of specific types and specifications, and cannot flexibly cope with sample tubes of different sizes and shapes, limiting their application scenarios.

[0027] The installation steps of this specific implementation are as follows:

[0028] 1. Install the 694 bearings on both sides of the five-hole cap removal claw cap throwing assembly with the left and right support plates of the five-hole cap removal respectively;

[0029] 2. Fix and connect the five-hole uncapping lifting mechanism assembly to the left and right support plates of the five-hole uncapping; then install the five-hole uncapping lifting slider mounting plate and the five-hole uncapping claw cap throwing assembly on the five-hole uncapping lifting mechanism assembly to the five-hole uncapping lifting base for connection and fixation;

[0030] 3. Place the swing cap-throwing slide assembly between the left and right support plates of the five-hole cap-throwing slide, wherein the five-hole cap-throwing slide sleeve on the swing cap-throwing slide assembly is placed in the corresponding groove of the support plate;

[0031] 4. Install the drive motor on the five-hole cap-removing swing motor bracket in advance. After installation, connect and fix the five-hole cap-removing skateboard rocker arm and the drive motor shaft through the top screw; then after the whole is assembled, fix it to the left support plate of the five-hole cap-removing skateboard; the protruding pin on the five-hole cap-removing skateboard rocker arm needs to be inserted into the corresponding slot of the five-hole cap-removing skateboard;

[0032] 5. Then clip one end of the cap reset spring to the left support plate of the five-hole cap removal, and clip the other end to the corresponding hole on the five-hole cap removal and cap throwing slide;

[0033] 6. After all components are installed, finally install the side panels of the decapping funnel and the left and right support plates of the five-hole decapping.

[0034] The working principle of this specific implementation method:

[0035] 1. Place the test tube rack with test tubes on the synchronous belt, and drive it through the track drive motor to rotate the conveyor belt wheel, thereby driving the test tube parts of the synchronous belt to move; the two five-hole cap-removing conveyor belt rear baffles can guide the test tube rack being transported; and the multiple sets of sensors installed will transport the test tube rack to the specified position;

[0036] 2. Driven by the cap removal lifting motor, the screw-02 on the motor itself will rotate, which will then drive the DZ57 cap removal linear nut to rotate, and finally drive the five-hole cap removal lifting slider mounting plate to move repeatedly on the linear guide rail; thereby driving the five-hole cap removal claw cap throwing assembly to move up and down; the test tube will be lifted to a certain height;

[0037] 3. When the test tube rack of the test tube runs between the left and right support plates of the five-hole decapping, the sensor detects that the test tube rack has reached the specified position, and then gives a signal to the decapping tube holding motor, so that the decapping tube holding motor drives the self-contained screw rod to rotate, and then drives the indirectly connected five-hole decapping tube holding inclined support arm AR3-T0804 and the five-hole decapping symmetrical rotating arm to perform connecting rod movement, thereby driving the front assembly of the five-hole decapping eccentric rotating arm to rotate, so that the symmetrical five-hole decapping single tube clamp block assembly holds the test tube tightly;

[0038] 4. At this time, the four cap-throwing swing arms cooperate with each other. At this time, through the drive of the cap-removing lifting motor and the action of the swing rods on both sides in the corresponding slots of the left and right support plates of the five-hole cap-removing, the swing arms can be connected to move, so that when the cap-removing claws are lifted to the top of the five-hole cap-removing lifting base, the pipe caps are translated through the corresponding holes on the five-hole cap-removing and cap-throwing push blocks, and then the pipe caps follow the horizontal movement of the five-hole cap-removing and cap-throwing push blocks to push them into the side plates of the cap-removing funnel, and slide from them to the designated position, completing the cap-throwing effect;

[0039] 5. When the five-hole cap-removing claw assembly rises to a certain height, the track drive motor drives the five-hole cap-removing skateboard rocker arm to rotate, so that the protruding pins on the five-hole cap-removing skateboard rocker arm and the corresponding slots of the five-hole cap-removing and cap-throwing skateboard cooperate with each other, so that the swinging cap-throwing skateboard assembly rotates a certain angle and rotates to the bottom of the five-hole cap-removing and cap-throwing push block assembly at the same time; at this time, the downward movement of the five-hole cap-removing claw cap-throwing assembly will press the lifted test tube into the corresponding test tube rack, and when the five-hole cap-removing claw cap-throwing assembly is lifted again, the swinging cap-throwing skateboard assembly will be pulled to the specified position through the cap reset tension spring, thereby completing the overall cap-removing movement; the cap-removing operation is repeated in sequence.

[0040] This specific implementation method is driven by a motor and realizes a relatively complicated uncapping process through the cooperation of a lead screw and a connecting rod. The overall manufacturing cost is relatively cheap, and the precise moving position is controlled through the clever cooperation of various mechanisms. The efficiency of uncapping a single tube is greatly improved during use, and this mechanism can be expanded into multiple rows, not just for simply uncapping 5 test tubes. It has a wide range of uses and can be applied to different occasions. The circuit components of this mechanism are all assisting in the movement of the coordinated structure.
