[0034] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0035] For ease of understanding, the application scenario of the utility model is first described. The application is used to load materials in the silo onto the loading platform. The specific structure is referred to as Figure 1 As shown, a glass slide tray 22 carries a number of glass slides 23, and the glass slide tray 22 is placed in a silo. The material transfer mechanism 3 takes materials from a fixed position in the silo 2 and loads the materials onto the loading platform. Since the materials in the silo 2 are distributed layer by layer and the top of the silo is capped, it is inconvenient to manually observe and confirm whether there is a glass slide tray on the loading station due to space limitations. Therefore, it is necessary to be able to quickly determine the materials in the silo 2 and load the materials onto the loading platform 1 to meet the needs of rapid scanning of samples.

[0036] A material loading mechanism applied to a microscope system comprises a material transfer mechanism 3 installed on a stage 1, wherein the material transfer mechanism 3 moves according to a preset moving trajectory to transfer the material on the loading station of a silo 2 to the area of ​​a waiting inspection station 10 of the stage 1.

[0037] The loading station is the position where the material transfer mechanism 3 takes the material from the silo 2. Figure 2 Combined with Figure 3 As shown in the figure, the loading station is the position where the topmost glass slide tray 22 inside the silo is located, and a first detection unit 4 is installed at the bottom of the table top of the stage 1. The first detection unit 4 identifies the glass slide 23 to determine whether there is a glass slide tray 22 on the loading station and whether the corresponding glass slide tray 22 is valid (has material); a second detection unit 5 is arranged on the stage 1, and the second detection unit 5 is used to detect whether there is material in the area of ​​the station to be inspected 10, and the position of the material in the area of ​​the station to be inspected 10. The second detection unit 5 adopts a second sensor, and the second sensor is installed on the outer edge of the station to be inspected area on the surface of the stage through a second support seat. The second sensor detects the material on the stage 1 to determine whether there is material and the position of the material.

[0038] When it is determined that there is a glass slide tray 22 at the loading station and there is a glass slide 23 on the glass slide tray 22, the material transfer mechanism 3 is controlled to transfer the material, and each time it moves horizontally to one side of the silo 2 to hook the topmost glass slide tray 22 to load the stage 1. When it is detected that there is material and the position of the material at the inspection station 10, the focus and position of the microscope are adjusted to align it with the material (sample) on the glass slide tray 22.

[0039] The slide plate 22 is made of light-colored, glossy material, such as silver-white, and is made of stainless steel, which facilitates sensor recognition and improves the recognition accuracy of the sensor.

[0040] When the specifications and sizes of the silo 2 are different, the distance between the silo 2 and the side of the loading platform 1 changes, causing the detection distance of the first sensor 40 to change. The fixed position of the first sensor 40 is not convenient for adapting to the recognition accuracy level caused by the distance change.

[0041] Therefore, this embodiment further configures the first detection unit to be adjustable to accommodate the recognition accuracy and precision issues caused by the size of the silo.

[0042] Specifically, the first detection unit 4 includes a carrier rod 41 and a first sensor 40. The first sensor 40 is fixed on the carrier rod 41. The carrier rod 41 is installed on the stage 1 through a support seat 42. A first adjustment component for adjusting the position of the first sensor 40 is provided on the support seat 42. Figure 6 The carrying rod 41 is placed through the supporting seat 42, and the first adjusting component adjusts the horizontal distance between the first sensor 40 and the silo 2 by rotating.

[0043] For the first adjustment component, in one embodiment, refer to the attached Figure 5 Cross-sectional view, combined with the attached Figure 6 A partial three-dimensional schematic diagram shows that a threaded section 43 is constructed on the carrier rod 41, and a threaded through hole 44 is constructed inside the support seat 42. The carrier rod 41 is installed through the threaded through hole 44. The upper top of the support seat 42 is fixedly connected to the bottom surface of the loading platform 1. The threaded section on the inner wall of the threaded through hole 44 is matched with the threaded section 43. The carrier rod 41 is rotated and screwed into or out of the threaded through hole 44, thereby driving the first sensor 40 to move horizontally and linearly between the silo 2 and the loading platform 1.

[0044] In another embodiment, the driving mechanism of the carrier rod 41 adopts a combination of a screw rod and a motor. Figure 7 The screw is fixed on the bottom surface of the loading platform 1, and the proximal end of the carrying rod 41 is installed on the support seat 42. The support seat 42 is fixedly connected to the moving end of the screw. The motor (not shown) drives the screw to rotate, driving the moving end (slider) to drive the carrying rod 41 to move horizontally and linearly between the silo 2 and the loading platform 1 during operation.

[0045] The silo 2 includes a silo housing 21 and a glass tray 22 for placing materials. Figure 3 As shown, the glass slide trays 22 are arranged layer by layer along the longitudinal direction of the silo 2, and a plurality of material stations 20 for glass slides 23 are arranged in parallel in each layer of the glass slide tray 22. Figure 4 A plurality of blocks 24 and springs 25 are arranged around the material station 20, and the blocks 24 and springs 25 cooperate with each other to limit and fix the glass slide 23 on the corresponding material station.

[0046] See attached Figure 1The material transfer mechanism 3 includes a hook plate 31, a movable slide rail 32, and a power member 33 for driving the hook plate 31 to move; the hook plate 31 is installed on the far side of the inspection station 10 area and the silo 2, and the hook plate 31 moves along the movable slide rail 32 to the side where the silo 2 is located, and the hook on the hook plate 31 is correspondingly hooked into the grabbing hole 34 of the glass slide tray 22 on the material station 20, thereby pulling the glass slide tray 22 and transferring the glass slide tray 22 to the inspection station 10 area.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
