[0025] Next, refer to the attached Figure 1 to the attached Figure 3 Describe the automatic slide loading mechanism in the liquid-based slide making instrument of the present utility model.

[0026] During the liquid-based slide making process, it is necessary to keep the slide 5 clean and pollution-free and place and position it quickly and accurately. When manually repeating the operation while wearing gloves, it is not easy to separate the adsorbed slide, and it is easy to place more; and it is not easy to place the slide correctly in the positioning groove 201, with low efficiency and easy to make mistakes.

[0027] Therefore, the present utility model provides an automatic slide loading mechanism in a liquid-based slide making instrument, as Figure 1As shown in the figure, it includes a loader 1 and a slide tray 2. The loader 1 is provided with a slide box 4 for accommodating slides 5. The slide box 4 is provided with a slide outlet 401. The slide tray 2 is provided with a positioning groove 201. The position of the slide outlet 401 matches that of the positioning groove 201 to accurately place the slide 5 on the positioning groove 201. The loader 1 is provided with a reciprocating slide pushing system 3, and the reciprocating slide pushing system 3 sequentially and accurately places the slides 5 on different positioning grooves 201.

[0028] As Figure 2 and Figure 3 shown in the figure, the slide box 4 includes a base 402 and a cover 403. The base 402 is fixedly connected to the loader 1, and the cover 403 is detachably connected to the base 402. After the base 402 and the cover 403 are connected, they jointly form a receiving cavity for the slides 5.

[0029] Preferably, one side of the cover 403 is detachable to facilitate the batch loading of the slides 5 into the receiving cavity.

[0030] The base 402 is provided with a lifting seat 404, and the lifting seat 404 is provided with a lifting end 405. The lifting end 405 abuts against the bottom surface of the slide 5 in the slide box 4 to lift the slide 5 to the height of the slide outlet 401.

[0031] Optionally, the driving source of the lifting seat 404 can be passive, that is, using a deformable elastic element such as a spring. The driving source of the lifting seat 404 can also be active, that is, using a driving mechanism that can provide linear motion such as a DC motor, a stepping motor, a lead screw, a rack and pinion, etc. When in use, select a suitable driving source as needed to complete the operation of lifting the slide 5.

[0032] Optionally, a first through hole 406 is opened on the base 402. A first vertical rod 407 is movably connected in the first through hole 406. A horizontal connecting rod 408 is fixedly connected to the first vertical rod 407. A second vertical rod 409 is fixedly connected to the horizontal connecting rod 408. The first vertical rod 407, the horizontal connecting rod 408 and the second vertical rod 409 jointly form a U-shaped rod. The end of the second vertical rod 409 far from the horizontal connecting rod 408 is fixedly connected to the lifting end 405. The lifting seat 404 drives the first vertical rod 407 to move to control the lifting end 405 to lift the slide 5. Specifically, the second vertical rod 409 extends into the receiving cavity. The lifting seat 404 drives the first vertical rod 407 to move upward, and the first vertical rod 407 drives the lifting end 405 on the second vertical rod 409 to move upward to lift the slide 5 to the height of the outlet 401.

[0033] Preferably, the lifting seat 404 includes a lifting spring 4041, the lifting spring 4041 is sleeved with the first vertical rod 407, the first vertical rod 407 is provided with a first limit block 4042 at one end away from the horizontal connecting rod 408, one end of the lifting spring 4041 abuts against the first limit block 4042, and the end of the lifting spring 4041 away from the first limit block 4042 abuts against the base 402. Specifically, after a plurality of stacked slides 5 are installed in the accommodating cavity, the lifting end 405 is in contact with the bottom The glass slides 5 abut against each other, and the thickness of multiple glass slides 5 causes the second vertical rod 409 to move downward, driving the first vertical rod 407 to move downward. At this time, the lifting spring 4041 produces elastic deformation. When the glass slide 5 located at the top is pushed out, the lifting spring 4041 releases the elastic force, and the lifting spring 4041 drives the first vertical rod 407 to move upward through the first limit block 4042. The first vertical rod 407 drives the second vertical rod 409 to move upward, so that the remaining glass slides 5 are lifted.

[0034] A second limit block 4043 is disposed on the first vertical rod 407 . The second limit block 4043 is disposed close to the horizontal connecting rod 408 , so that the second limit block 4043 can abut against the base 402 to limit the upward displacement of the first vertical rod 407 .

[0035] The lifting seat 404 includes a positioning rod 4044, which is fixedly connected to the base 402, and a first limit block 4042 is slidably connected to the positioning rod 4044 so that the U-shaped rod moves along the direction of the positioning rod 4044. Preferably, a second through hole 4045 is opened on the first limit block 4042, and the second through hole 4045 is slidably connected to the positioning rod 4044.

The slide pushing motor 301 is fixedly connected to the loader 1, and the driven wheel 302 is fixedly connected to the loader 1. The output end of the slide pushing motor 301 and the driven wheel 302 are connected through a belt 303. A slide pusher 304 is fixedly connected to the belt 303. The reciprocating slide pushing system 3 pushes the slide 5 out of the slide box 4 through the slide pusher 304.

[0037] The slide push rod 304 is provided with a positioning piece 100 , and the slide box 4 is provided with a positioning groove 200 , the positioning groove 200 matches the shape of the positioning piece 100 , and the positioning piece 100 can slide relative to the positioning groove 200 so that the slide push rod 304 can accurately push out the slide 5 .

[0038] A driving motor 202 is provided on the slide tray 2, and the output end of the driving motor 202 is connected to the slide tray 2 to drive the slide tray 2 to move. The motion parameters of the driving motor 202 match the motion parameters of the slide pushing motor 301 to achieve fully automatic continuous loading of the slides 5.

[0039] Working principle of the present utility model: After the slide box 4 is installed, the lifting end 405 presses against the cover glass slide 5 from the bottom end of the glass slide 5.

The first glass slide 5 falls into the positioning groove 201 of the slide tray 2. The second glass slide 5 is lifted by the lifting end 405 under the action of the lifting spring 4041. The slide pushing motor 301 and the driving motor 202 are started. The driving motor 202 drives the slide tray 2 to move. The slide tray 2 aligns the empty positioning groove 201 with the outlet 401 of the glass slide 5. The slide pushing motor 301 continues to push out the second glass slide 5, and the second glass slide 5 also falls into the positioning groove 201 of the slide tray 2. And so on until all the glass slides 5 are pushed out.
