[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0042] Example 1:
[0043] like Figure 1-8 As shown, the present invention provides a light source structure 8 based on a high-precision digital slide scanning device 9. The light source structure 8 is located at the bottom of the Z-axis optical path of the high-precision digital slide scanning device 9 and is used to provide light source when imaging. The light source structure 8 includes: a base 1, a light source assembly 4, a light shielding member 2, and a driving member 3;
[0044] An installation space is provided in the base 1, and a light source channel is provided in the installation space; the light source assembly 4 is provided in the installation space, and the light-emitting position of the light source assembly 4 is opposite to the entrance of the light source channel; the shading member 2 is provided in the base 1 and can slide along a first direction, the first direction is the direction toward the exit of the light source channel, and the size of the shading member 2 is adapted to the size of the exit of the light source channel; the driving end of the driving member 3 is connected to the shading member 2, and is used to drive the shading member 2 to slide closer or away in the first direction.
[0045] Specifically, the light source structure 8 of the first embodiment of the present invention is configured by providing an installation space and a light source channel within the base 1, utilizing the installation space to install the light source assembly 4, so that the light source of the light source assembly 4 is projected along the light source channel to serve as the light source required for digital slice scanning imaging. At the same time, in order to conveniently control the opening and closing of the light source, the driver 3 is utilized to drive the shading member 2 to block or release the exit of the light source channel, thereby controlling the opening and closing of the exit of the light source channel. At the same time, the shading member 2 is slidably connected to the base 1, and slides toward or away from the exit of the light source channel along a first direction, that is, the sliding track formed by the sliding is in a fixed direction, so that the shading member 2 slides on the fixed slide, ensuring the stability of the movement during shading.
[0046] In some preferred embodiments, Figure 4-5 As shown, the light shielding member 2 includes a first grating 201, and the light source structure 8 further includes a second grating 202. The second grating 202 is arranged at the exit of the light source channel. The slits on the first grating 201 are adapted to the size of the notches on the second grating 202. When the driving member 3 drives the first grating 201 to slide to the end of the first direction, the first grating 201 and the second grating 202 overlap, so that all the slits of the first grating 201 are embedded with the corresponding notches of the second grating 202 to form an opaque panel.
[0047] It can be understood that a grating is an optical device composed of a large number of parallel slits of equal width and equal spacing. That is, a number of scratches are etched at equal intervals on a light-transmitting material. The scratches are opaque, and the slits between adjacent scratches are used to transmit light. Based on this, in the first embodiment, a second grating 202 is provided at the exit of the light source channel. To achieve a light-shielding effect, after the first grating 201 is slid and moved to overlap directly above the second grating 202, the scratches of the first grating 201 and the slits of the second grating 202 are staggered, and will one-to-one block the slits on the second grating 202, thereby achieving the purpose of light-shielding.
[0048] In some preferred embodiments, the driving member 3 includes a motor 301, a large gear 303 and a small gear 302. The motor 301 is arranged on the side wall of the base 1, and the axis of the small gear 302 is coaxially connected to the driving end of the motor 301. The large gear 303 is sleeved on the outer periphery of the base 1 and can rotate freely relative to the base 1. The shading member 2 is arranged on the side of the large gear 303 close to the exit of the light source channel through a connecting member 6.
[0049] In this way, when it is necessary to control the light shielding member 2 to block the light source, the motor 301 can be started to rotate to drive the small gear 302, thereby causing the large gear 303 meshing with the small gear 302 to be driven, causing the light shielding member 2 to move in the first direction of the above-mentioned embodiment to the exit position of the light source channel. When it is necessary to control the light shielding member 2 away from the exit position of the light source channel, the motor 301 can be started to rotate to drive the small gear 302, thereby causing the large gear 303 meshing with the small gear 302 to be driven, causing the light shielding member 2 to move in the first direction away from the exit position of the light source channel. Furthermore, in order to control the rotation accuracy of the small gear 302 and the large gear 303, the motor 301 in this embodiment can be a stepper motor 301.
[0050] In some preferred embodiments, the driving member 3 further comprises a ball bearing, the inner ring of which is sleeved on the outer periphery of the base 1, and the large gear 303 is sleeved on the outer ring of the ball bearing. This can reduce friction when the gear rotates, making the rotation smoother.
[0051] In some preferred embodiments, the connecting member 6 is in the shape of a handle.
[0052] In some preferred embodiments, the light source structure 8 further includes a sensor plate 7 , and the sensor plate 7 is provided on the connecting member 6 .
[0053] In some preferred embodiments, the light source structure 8 further includes a connecting support 5, which includes an annular connecting portion and a pair of ear plates arranged on symmetrical sides of the annular connecting portion, and the ear plates are provided with connecting holes for connecting to external devices through the connecting holes.
[0054] This is to facilitate the light source structure 8 and the high-precision digital slice scanning device 9 to better form an integrated connection structure. For example, when the various components of the high-precision digital slice scanning device 9 are connected through a basic connector, the connecting support 5 can be connected to the basic connector through the connecting hole to form an integrated high-precision digital slice scanning device 9.
[0055] In some preferred embodiments, the shading member 2 is a light-proof plate-shaped structure.
[0056] Example 2:
[0057] This second embodiment provides a high-precision digital slide scanning device, comprising a light source structure based on any of the above-described high-precision digital slide scanning devices. The device utilizes the light source structure to provide an installation space and a light source channel within a base. The installation space is used to house a light source assembly, allowing light from the light source assembly to be emitted along the light source channel to serve as the light source required for digital slide scanning imaging. Furthermore, to facilitate the on / off control of the light source, a driver drives a light shielding member to block or release the light source outlet, thereby controlling the on / off of the light source.
[0058] It is easy for those skilled in the art to understand that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
