Description

Multi-slide bearing device of microscope

Technical Field

The utility model relates to the technical field of microscopes, in particular to a microscope carrying device.

Background

The object of most microscopic observation, represented by biological microscopes, is an extremely thin, partially transparent specimen slice. Specimen slices are fixed above a fixed size and large piece of glass slide (referred to as a slide) and below a small piece of coverslip via a preparation process. When viewing is desired, the user holds the slide on the stage by means of the slide clamp, and can then manipulate the stage to move the slide.

The traditional microscope is used for manually loading and unloading slides one at a time, and the flow is generally as follows: one hand opens the slide clamp and the other hand places the slide on the stage, pushes it into the slide clamp position and releases the slide clamp.

After the appearance of a digital microscope and an automatic slice scanner, the observation or scanning function is semi-automatic or automatic without manual intervention, and the main manual work is reduced to loading and unloading slices. In this situation, the slide needs to be frequently replaced on the single stage, which is slow and inconvenient to operate, and thus demands for a microscope and a slide scanner capable of loading multiple slides are met.

The following scheme is generally adopted at present for realizing loading of multiple pieces at a time:

1. a plurality of glass clips are simply copied from front to back at the position of an original single glass clip to respectively clip each glass, and a user needs to put the glass clips into the corresponding glass clips one by one when loading the glass. However, for a scanner with the stage stored in the protective housing, it is inconvenient to reach the device to operate the stage, and the multiple glass clips abutting against each other can block and interfere with the operation.

2. The device is provided with a relatively complex loading and unloading mechanical arm structure, only one slide is still loaded on the objective table, but the mechanical arm automatically completes the loading and unloading of the slide and a large amount of users who process hundreds of slides at one time, and the device has good expansibility. However, such equipment is cost prohibitive for small volume users who process two or three slides at a time.

3. The design of moving and replacing slides by special carrying structures, such as 201110071788.1 and 201810020950.9, is simple compared with a mechanical arm, but has poor universality and stability and still higher implementation cost.

Therefore, it is of great value to design a microscope stage that can conveniently load multiple slides at one time without the support of a mechanical arm.

Detailed Description

Examples

Referring to fig. 1 and 2, the present invention comprises a microscope multi-slide carrier comprising a base 1 and a tray 4.

The base 1 is intended to be fixed to the stage of a microscope. In practice, the scanner stage may be permanently mounted on the scanner stage by mechanical means such as screws, or may be integrally formed with the scanner stage.

The tray 4 has a plurality of slide mounting positions for taking and placing the slides 3. In this embodiment, the slide mounting position is a plurality of hollow spaces arranged in parallel, a groove (not shown in the figure) for clamping the slide 3 is arranged on the side wall of one longitudinal end of each hollow space, and a spring slide top clamp 2 is arranged at the other longitudinal end of each hollow space, so that when the slide 3 is placed in the slide mounting position, the slide is fixed in position under the supporting action of the spring slide top clamp 2. As shown in fig. 3, it is particularly preferable that: spring slide top card 2 includes spring 8, top card 2 and fixed strip 9, and top card 2 is used for being the wedge towards the front of slide 3, and the back of top card 2 is connected to spring 8's one end, and spring 8's other end is fixed to tray 4, and fixed strip 9 strides to be established in top card top and fixed through screw 10, and fixed strip 9 forms the spacing of vertical direction to top card 2.

Certainly, due to the needs of different practical application scenarios, the two ends of the hollow-out position can also be provided with a glass slide clamping structure adopting a traditional elastic clamp, which is not described in detail.

In the present embodiment, the tray 4 is connected to the base 1 in a sliding manner, and therefore, it may be preferable that a sliding groove is provided on each of both lateral sides of a predetermined area on the base 1, through which the tray 4 is detachably fitted to the base 1. In this embodiment, a bottom stop is further provided between the pair of sliding grooves, so that the tray 4 can be slidably fitted to the base 1 only from the only remaining open position (i.e. the position of the large white arrow in fig. 5). As shown in fig. 4, when the tray 4 is slid into the slide grooves, both lateral sides of the tray 4 are adapted to be fitted into a pair of slide grooves. When taken out, the tray 4 is slid out along the direction of the large hollow arrow in fig. 5.

Of course, as for other alternative connection modes of the base 1 and the tray 4, it is conceivable that the connection assembly of the tray 4 and the base 1 can also be formed by arranging a clamping groove on the base 1, and the bottom of the tray 4 is integrally clamped in the clamping groove.

Regarding the accurate positioning of the tray 4 on the base 1, in the present embodiment, a tray 4 positioning mechanism is provided on each of the base 1 and the tray 4, and the tray 4 positioning mechanism is used to assist the accurate positioning of the tray 4 on the base 1. Particularly preferred are: the tray 4 mechanism of taking one's place includes two sets of magnets, and wherein first set of magnet 5 predetermines at the top surface reasonable position of base 1, and second set of magnet 6 predetermines at the bottom surface reasonable position of tray 4, and when the tray 4 assembly was on base 1 and the position is correct, the first set of magnet 5 was opposite with the one end opposite and the mutual proximity of second set of magnet 6 one end polarity. In order to achieve an exact alignment of the first set of magnets 5 and the second set of magnets 6, it may further be preferred that: in the first group of magnets 5 and the second group of magnets 6, the two magnets used for mutual attraction have the same area and shape. It is obvious that either the first group of magnets 5 or the second group of magnets 6 can be replaced by a magnetic conductive material, and even if the magnets are replaced, the magnets attract the magnetic conductive material, so that the obtained effect is basically the same.

To further prevent the tray 4 from being erroneously reversely assembled, it may be preferable that: the first set of magnets 5 is arranged in a non-mirrored arrangement on the two lateral halves of the base 1 and the second set of magnets 6 is arranged in a non-mirrored arrangement on the two lateral halves of the tray 4. Therefore, when the tray 4 is reversely loaded, the first group of magnets 5 and the second group of magnets 6 cannot be attracted due to the fact that the positions are not opposite, so that a user can notice that the tray 4 is reversed without a complex mechanical limiting device, and the user can easily correct the situation.

When the device in the embodiment is used, a plurality of glass slides 3 are loaded and fixed on the tray 4 in advance, and when the device is installed, the tray 4 is separated from the base 1, so that the operation from all directions can be conveniently carried out, one or more glass slides 3 are respectively loaded conveniently, the slide 3 does not need to slide into the slide 3 clamps on a microscope objective table, and the slide 3 clamps cannot be interfered with each other.

After the glass slide 3 is mounted on the tray 4, the tray 4 is matched on the base 1 in a sliding mode, and accurate positioning is achieved under the aligning and attracting effects of the first group of magnets 5 and the second group of magnets 6.

The present invention is not limited to the above embodiments, and the technical solutions of the above embodiments of the present invention may be combined with each other in a crossing manner to form a new technical solution, and all technical solutions formed by using equivalent substitutions fall within the scope of the present invention.
