[0020] It should also be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0021] The specific implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, this patent discloses an automated biological sample grinder of a disclosed embodiment, which includes an outer shell 1 , a grinding mechanism 2 and a loading mechanism 3 .

[0023] like Figures 1 to 5As shown, a support plate 11 arranged in a horizontal direction is arranged in the middle of the outer shell 1, and a part of the support plate 11 extends to the outside of the outer shell 1, and the interior of the outer shell 1 is divided into a lifting and fixing area 12 located at the upper part and a vibration fixing area 13 located at the lower part according to the horizontal arrangement direction of the support plate 11. A side opening 14 is arranged on the outer shell 1 in the lifting and fixing area 12, which is extended toward the support plate 11, and the container to be ground can be input into the grinder through the side opening 14.

[0024] The support plate 11 is provided with a through hole 15 for connecting the lifting fixing area 12 and the vibration fixing area 13. The position of the through hole 15 corresponds to the position of the vibration plate 217 described later, so as to facilitate connecting the vibration assembly 21 described later on the vibration plate 217. In this embodiment, the vibration assembly 21 is used to drive the vibration plate 217 to reciprocate up and down.

[0025] like Figures 1 to 3 As shown, the grinding mechanism 2 includes a vibration plate 217 of a vibration assembly 21 and a cover plate 224 of a lifting and fixing assembly 22. A grinding area (the grinding area is opposite to the side opening 14) is provided on the upper surface of the vibration plate 217. The cover plate 224 is provided above the grinding area so as to be movable up and down. When a container (not shown) is placed in the grinding area, the cover plate 224 can move downward to close the top of the container, and then the vibration plate 217 can vibrate to grind the sample in the container. The vibration of the vibration plate 217 can be reciprocating up and down, or reciprocating left and right, or reciprocating back and forth, or any combination of the above.

[0026] It should be noted that the container is a device for holding a sample, such as a test tube, a tray with one or more grooves, etc. As an example, the container can be a deep well plate, especially a 96-well deep well plate. Before grinding, a sphere for promoting grinding, such as a tungsten carbide ball, a stainless steel bead, etc., is added to the container.

[0027] like Figures 1 to 3 As shown, the vibration component 21 of the grinding mechanism 2 is located in the vibration fixing area 13, and the lifting and fixing component 22 is located in the lifting and fixing area 12. The vibration component 21 and the lifting and fixing component 22 cooperate to form a grinding area.

[0028] Specifically, the vibration assembly 21 includes a vibration motor 212, an eccentric block 213, a connecting rod 214, a lifting shaft 215, a linear bearing 216 and a vibration plate 217; an eccentric block 213 is installed on the output shaft of the vibration motor 212, the lower end of the connecting rod 214 is transmission-connected to the eccentric block 213, the upper end of the connecting rod 214 is rotationally connected to the lower end of the lifting shaft 215, the eccentric block 213, the connecting rod 214 and the lifting shaft 215 form a crank slider mechanism, and when the vibration motor 212 drives the eccentric block 213 to rotate, the lifting shaft 215 performs a lifting motion. The lifting shaft 215 is passed through the linear bearing 216 to facilitate the lifting movement. The upper end of the lifting shaft 215 is fixedly connected with a screw rod, and the upper end of the screw rod passes upward from the vibration plate 217. The nut is threadedly connected to the screw rod, and the nut abuts against the upper surface of the vibration plate 217, fixing the vibration plate 217 on the screw rod along the axial direction (horizontal direction). Therefore, when the lifting shaft 215 performs a lifting movement, the vibration plate 217 performs a lifting movement accordingly.

[0029] In order to reduce the vibration of the vibration component 21 during movement, a plurality of vertically arranged shock absorbing springs 211 are arranged at the bottom of the vibration fixing area 13 of the outer shell 1, and a first fixing plate 218 is arranged on the top of the shock absorbing spring 211, and the above-mentioned vibration motor 212 is fixedly installed on the top surface of the first fixing plate 218. A second fixing plate 219 connected to and arranged in parallel with the first fixing plate 218 is arranged above the first fixing plate 218, and a linear bearing 216 is arranged on the second fixing plate 219.

[0030] The lifting and fixing assembly 22 includes a lifting motor 221, an active rotating member 222, a passive rotating member 223 and a cover plate 224; the lifting motor 221 is installed at the inner top of the lifting and fixing area 12 of the outer shell 1, and the output shaft of the lifting motor 221 is fixedly connected to the active rotating member 222 to drive the active rotating member 222 to rotate. The active rotating member 222 and the passive rotating member 223 are mutually engaged. When the active rotating member 222 rotates, the passive rotating member 223 rotates accordingly. The passive rotating member 223 is threadedly connected to the screw rod. Therefore, when the active rotating member 222 drives the passive rotating member 223 to rotate, the passive rotating member 223 can move axially on the screw rod. The cover plate 224 mentioned above abuts against the lower end of the passive rotating member 223. Therefore, when the passive rotating member 223 moves axially, the cover plate 224 performs a lifting movement.

[0031] like Figures 1 to 6 As shown, the feeding mechanism 3 includes a limiting plate 31 , a feeding plate 32 and a moving assembly 33 .

[0032] The limit plate 31 is arranged on the top of the support plate 11 and close to the side opening 14. A first slide groove 34 is arranged along the straight line L1 direction on one side of the limit plate 31 close to the opening, and a second slide groove 16 is arranged along the straight line L1 direction on the support plate 11. The second slide groove 16 is located directly below the first slide groove 34.

[0033] The loading plate 32 vertically passes through the first slide groove 34 and the second slide groove 16, and its upper and lower ends are respectively located above and below the limit plate 31, and its lower end is fixedly connected to the moving plate 333 of the moving assembly 33 described later. The moving assembly 33 controls the loading plate 32 to move toward or away from the grinding area.

[0034] The moving assembly 33 includes a moving motor 331 fixedly connected to the bottom of the support plate 11, a transmission component 332 transmission-connected to the moving motor 331, and a moving plate 333 for connecting the transmission component 332 and the loading plate 32; the power input end of the transmission component 332 is connected to the output shaft of the moving motor 331, the transmission component 332 converts the rotational motion of the output shaft into linear motion of the power output end of the transmission component 332, and the moving plate 333 is connected to the power output end of the transmission component 332.

[0035] The specific transmission component 332 is but not limited to a screw rod 334 arranged along the straight line L1 and a slider 335 connected to the screw rod 334. One end of the screw rod 334 is connected to the output shaft of the moving motor 331, and the bottom end of the slider 335 is fixedly connected to the moving plate 333.

[0036] like Figures 1 to 7 As shown, the loading principle of the loading mechanism 3 is as follows: the container to be ground is placed on the limit plate 31, and the side away from the side opening 14 is abutted against the limit plate 31, and the loading plate 32 is driven toward the side opening 14 by driving the moving component 33 until the container is delivered into the grinding area, and then the moving component 33 is driven to reset the loading plate 32.

[0037] Since the grinder is a fully automatic grinder, it is also necessary to automatically take out the container after grinding, so an inclined surface 35 is provided on the top of the loading plate 32 facing the side opening 14. When the grinder needs to be taken out, it is only necessary to repeat the above steps of sending the container to the grinding area so that the inclined surface 35 of the loading plate 32 abuts against the container, and then continue to drive the moving assembly 33 so that the loading plate 32 slides in through the inclined surface 35 and is clamped to the bottom or the other side of the container, and then the loading plate 32 is driven back to the original position to complete the work of taking out the grinder.

[0038] Among them, the above-mentioned container is an existing structure and will not be described in detail. A groove for clamping the loading plate 32 may be provided at the bottom of the container.

[0039] like Figure 1 , Figure 2 and Figure 5 As shown, in order to better fix and stabilize the container, a container placement area 36 is provided on the limiting plate 31, which is recessed downward and arranged in the same direction as the first slide groove 34, and both sides of the container placement area 36 are provided with a certain inclination angle.

[0040] like Figure 1 As shown, an electric lift door 4 is installed on the side opening 14 of the grinding area, and the electric lift door 4 can switch between completely covering the side opening 14 (when grinding) and completely exposing the side opening 14 (when not grinding), which can better protect the container. Since the electric lift door 4 is conventional technology, it will not be described in detail.

[0041] Since the grinder is fully automatically controlled, a control module that can control the grinding mechanism 2 and the feeding mechanism 3 can be arranged on the outer shell 1 .

[0042] The above is a description of the embodiments of the present invention. Through the above description of the disclosed embodiments, professionals and technicians in the field can implement or use the present invention. Various modifications to these embodiments will be apparent to professionals and technicians in the field. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown in this article, but will conform to the widest range consistent with the principles and novelties disclosed herein.
