[0005] 2) The process is cumbersome and the work efficiency is extremely low.

[0006] 3) When operating manually, each step requires careful identification and operation, involving a large amount of repetitive work, which is very tiring.

[0007] 4) High risk of increased exposure to biological hazards.

[0008] There is an urgent need for an automated embedding cassette transfer device to facilitate the switching and placement of embedding cassettes in a prescribed order for samples. Utility Model Content

[0009] This invention provides an embedding box collection device to solve at least one of the above-mentioned technical problems.

[0011] It also includes a support base and a rotary drive mechanism for driving the sample tray to rotate circumferentially. The rotary drive mechanism is installed on the lower side of the support base. The rotary drive mechanism drives the rotating shaft to rotate. The rotating shaft is rotatably connected to the support base through a bearing, and the top of the rotating shaft is detachably connected to the center of the sample tray.

[0012] This invention utilizes the rotation of the embedding cassette to switch between different embedding cassettes for receiving samples, thereby achieving sequential sample placement. The optimized sample tray structure facilitates the placement of the embedding cassettes in an open position. The rotation drive mechanism is located below the support base, which in turn provides dust protection for the mechanism.

[0013] More preferably, the overlapping protrusion is an annular protrusion.

[0014] More preferably, the sample tray is detachably connected to the overlapping protrusion.

[0015] It facilitates the replacement of overlapping protrusions of different heights and the adjustment of the embedding box opening.

[0016] More preferably, the rotary drive mechanism includes a driving pulley and a driven pulley arranged horizontally side by side, the driving pulley and the driven pulley being connected by a belt drive;

[0017] The driven pulley is detachably mounted on the rotating shaft;

[0018] A ring-shaped baffle is detachably connected to the lower side of the driven pulley;

[0019] The belt is located on the upper side of the annular baffle.

The driven pulley rotates 360° in one revolution, and the driving pulley rotates 2880° in eight revolutions. The spacing between each sample is 18°. The driving pulley rotates 144° for every 144° rotation, and the driven pulley rotates 18° for every 18° rotation.

[0037] Assuming the embedding box is currently at position N, the target position is N+X. Therefore, the rotation degree of the driven pulley is 18°*X, and the rotation degree of the driving pulley is 18°*X*8.

[0038] Further preferably, a trigger structure is installed at the bottom of the sample tray, and a sensor for sensing the trigger structure is detachably connected to the support base. This facilitates precise positioning of the rotational position by providing a trigger structure at the zero-point of the sample tray's rotation.

[0039] When the triggering structure is a sensing hole, the sensor is a photoelectric proximity sensor;

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] Please see Figures 1 to 6 As shown in Specific Embodiment 1, an embedding cassette collection device includes a sample tray 1 for placing open embedding cassettes. The sample tray 1 has circumferentially arranged placement grooves, and an overlapping protrusion 7 for supporting the lid of the embedding cassette is connected to the sample tray 1. The overlapping protrusion 7 is located inside the placement grooves. It also includes a support base 3 and a rotary drive mechanism for driving the sample tray 1 to rotate circumferentially. The rotary drive mechanism is installed on the lower side of the support base 3 and drives a rotating shaft 2 to rotate. The rotating shaft 2 is rotatably connected to the support base 3 via bearings, and the top of the rotating shaft 2 is detachably connected to the center of the sample tray 1. This invention achieves sequential sample placement by rotating the embedding cassettes and switching between different embedding cassettes to receive samples. By optimizing the structure of the sample tray 1, it is easy to place the embedding cassettes in an open state. By placing the rotary drive mechanism on the lower side of the support base 3, the support base 3 serves as a dustproof shield for the rotary drive mechanism.

[0054] The overlapping protrusion 7 is an annular protrusion. The sample tray 1 is detachably connected to the overlapping protrusion 7. This facilitates the replacement of overlapping protrusions 7 with different heights and the adjustment of the embedding box opening.

[0055] The rotary drive mechanism includes a drive motor 4, a drive pulley, and a driven pulley 5; the drive pulley is installed at the power output end of the drive motor 4, and the drive pulley is connected to the driven pulley 5 via a belt 6; the driven pulley 5 is detachably mounted on the rotating shaft 2.

[0057] The sample tray has 20 slots arranged in a 360-degree circle for placing samples. Each slot is spaced 18° apart (each sample is spaced 18° apart). The driven pulley rotates 360° in one revolution, and the driving pulley rotates 2880° in eight revolutions. Each sample is spaced 18° apart. For every 144° rotation of the driving pulley, the driven pulley rotates 18°. Assuming the embedding cassette is currently at position N, the target position is N+X. Therefore, the driven pulley rotates 18°*X, and the driving pulley rotates 18°*X*8.

[0058] A trigger structure is installed at the bottom of the sample tray, and a sensor for sensing the trigger structure is detachably connected to the disc support. This allows for easy positioning of the rotational position by placing the trigger structure at the zero point of the sample tray's rotation. When the trigger structure is a sensing hole, the sensor is a photoelectric proximity sensor. The sensing hole is a vertical opening. The sensing direction of the photoelectric proximity sensor is upward. When the trigger structure is a magnet, the sensor is a magnetic sensor.

[0059] An annular baffle 11 is detachably connected to the lower side of the driven pulley 5; the belt 6 is located above the annular baffle 11 to prevent the belt 6 from coming loose. The driven pulley 5 is connected to the rotating shaft 2 by a locking screw.
