Description

Technical Field

[0001] This utility model relates to the field of sample tube cap removal technology, specifically to an automatic sample tube cap removal device. Background Technology

[0002] Currently available manual or semi-automatic decapping devices require operators to remove caps from each sample individually, increasing labor intensity, especially when processing large numbers of samples, significantly increasing the operator's workload. Because they need to process each sample individually, manual or semi-automatic decapping devices are relatively slow, failing to meet the needs of high-throughput experiments and impacting overall work efficiency. Manual operation requires a high level of skill and meticulousness, making it prone to errors, leading to sample contamination or damage, increasing experimental uncertainty and repetitive work. During manual operation, operators need to directly contact the sample tubes, posing certain safety hazards, especially when handling toxic, harmful, or flammable and explosive samples. Manual or semi-automatic devices cannot guarantee consistent force and angle for each decapping operation, potentially leading to incomplete decapping or sample spillage, affecting the accuracy and reliability of experimental results. Manual or semi-automatic devices typically can only handle specific types and sizes of sample tubes, unable to flexibly handle sample tubes of different sizes and shapes, limiting their application scenarios.

[0029] 2. The five-hole cap removal and conveying lifting mechanism assembly is also fixedly connected with the five-hole cap removal and conveying left and right side support plates. Then, the five-hole cap removal and conveying lifting mechanism assembly and the five-hole cap removal and conveying claw ejection assembly are connected and fixed on the five-hole cap removal and conveying lifting base.

Then, after the overall assembly is completed, it is fixed to the left support plate of the five-hole cap removal. The protruding pin on the five-hole cap removal slide plate rocker arm needs to be inserted into the corresponding slot of the five-hole cap removal cap throwing slide plate;

[0032] 5. Then, one end of the cap resetting tension spring is clamped to the left support plate of the five-hole cap removal, and the other end is clamped to the corresponding hole of the cap throwing slide plate of the five-hole cap removal;

[0033] 6. After the installation of each component assembly is completed, the cap removal funnel side plate is finally installed with the left and right support plates of the five-hole cap removal.

[0034] Working principle of the specific embodiment:

[0035] 1. The test tube rack with test tubes is placed on the synchronous belt, and the track driving motor is driven to rotate the transmission belt wheel, thereby driving the test tube of the synchronous belt to move. The two five-hole cap removal conveying belt rear baffles can guide the test tube rack being conveyed. The installed multiple sensors will transport the test tube rack to the specified position.

[0036] 2. The driving of the cap removal lifting motor will make the screw rod-02 on the motor itself rotate, thereby driving the DZ57 cap removal linear nut to rotate, and finally driving the five-hole cap removal lifting slide block mounting plate to move repeatedly on the linear guide rail, thereby driving the five-hole cap removal cap clamping jaw throwing assembly to move up and down, and lifting the test tube to a certain height.

[0037] 3. When the test tube rack runs between the left and right support plates of the five-hole cap removal, the sensor detects that the test tube rack reaches the specified position, and gives a signal to the cap removal tube holding motor, so that the cap removal tube holding motor drives the built-in screw rod to rotate, thereby driving the indirectly connected five-hole cap removal tube holding inclined support arm AR3-T0804 and the five-hole cap removal symmetrical rotating arm to move through the connecting rod, thereby driving the five-hole cap removal eccentric rotating arm front assembly to rotate, so that the symmetrical five-hole cap removal 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, the cap removal lifting motor is driven and cooperates with the swing rods in the corresponding clamping grooves of the left and right support plates of the five-hole cap removal, thereby realizing the connecting rod movement of the swing arm, so that when the cap pulling clamping jaw is lifted to the top of the five-hole cap removal lifting base, the cap is translated and moved through the corresponding hole of the five-hole cap removal cap throwing push block, and then the cap is horizontally moved with the five-hole cap removal cap throwing push block to push it into the cap removal funnel side plate, and then it slides to the specified position. The effect of throwing the cap is completed.

[0039] 5、When the five-hole cap pulling claw assembly rises to a certain height, the track drive motor drives the five-hole cap pulling slide rocker to rotate, so that the swing cap throwing slide assembly is rotated by a certain angle through the cooperation of the protruding pin of the five-hole cap pulling slide rocker and the corresponding slot of the five-hole cap throwing slide, and the five-hole cap throwing push block assembly is rotated to the position directly below; At this time, the five-hole cap pulling claw throwing assembly is moved downward, which will press the lifted test tube into the corresponding test tube rack, and when the five-hole cap pulling claw throwing assembly is lifted again, the swing cap throwing slide assembly will be pulled to the specified position through the cap resetting tension spring, thereby completing the overall cap pulling movement; and the cap pulling operation is repeated in turn.

[0040] The specific embodiment is driven by a motor, and the complicated cap pulling process is realized through the cooperation of the lead screw and the connecting rod. The overall manufacturing cost is relatively low, and the precise movement position is controlled through the ingenious cooperation of the mechanisms. In the use process, the efficiency of single tube cap pulling is greatly improved, and the mechanism can be expanded into multiple rows. The mechanism is not only used for pulling the caps of five test tubes, but also has a wide application prospect and can be used in different occasions. The circuit components of the mechanism are used for assisting the cooperation of the structure movement.
