Description

Technical Field

[0001] The utility model belongs to the technical field of microbial sample processing devices and relates to a loader transport mechanism, in particular to a microbial sample loader transport mechanism. Background Art

[0002] Microbial sample processing is widely used in colony inoculation, culture, separation, and detection. Microbial sample processing is an important task in medical health, inspection and quarantine, disease control, food safety, etc. For example, a Chinese patent discloses a microbial sample intelligent processing device [authorization announcement number is CN218596396U]. In order to facilitate the transfer of the loader (culture medium box), a preservation box and a lifting module are set below the workbench. The lifting module is used to transport the loader to the bottom of the preservation box. A moving module is set below the preservation box, and the moving module is used to drive the preservation box to move horizontally.

[0003] In order to position the storage box on the mobile module, an annular retaining edge is arranged around the storage box on the upper part of the mobile module. Since the inner ring size of the annular retaining edge matches the outer ring size of the storage box, if there is any negligence during placement, the storage box will not be able to enter the installation position accurately, so that the lower end of the storage box will be against the annular retaining edge, causing the storage box to tilt. Since the height of the annular retaining edge is relatively low and located at the edge of the storage box, the tilt of the storage box is not obvious, and it is impossible to clearly distinguish whether the storage box is installed in place by naked eyes. Utility Model Content

[0004] The utility model aims to solve the above problems in the prior art and proposes a loader transfer mechanism that can reduce the risk of misalignment.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] The loader transfer mechanism includes a base, a linear module arranged on the base, a transfer pallet driven by the linear module and a transfer box arranged on the transfer pallet. A positioning opening is provided at the bottom of the transfer box, and a limiting protrusion is provided on the transfer pallet to cooperate with the positioning opening. When the transfer box is installed in place, the limiting protrusion extends into the positioning opening.

[0007] The limiting protrusion and the positioning opening work together to position the transfer box. The limiting protrusion is set near the middle of the transfer box. When the positioning opening is not aligned with the limiting protrusion, the bottom surface of the transfer box rests on the limiting protrusion. At this time, the contact point between the bottom of the transfer box and the upper surface of the transfer pallet is the first point, and the contact point between the bottom of the transfer box and the upper surface of the limiting protrusion is the second point. The line connecting the first point and the second point is assumed to be the hypotenuse of the triangle, and the limiting protrusion is the height of the triangle. The closer the limiting protrusion is to the first point, the more inclined the hypotenuse of the triangle is, and the more inclined the transfer box is, which is convenient for direct observation with the naked eye and is conducive to timely installation of the transfer box.

[0008] In the above-mentioned loader transfer mechanism, one side edge of the bottom of the transfer box is recessed toward the middle to form the above-mentioned positioning opening, and a limiting bar is provided on the transfer pallet. The limiting bar extends along the recessed direction perpendicular to the positioning opening, and the installed transfer box is horizontally limited between the limiting protrusion and the limiting bar.

[0009] The positioning opening is designed to be open, so that the limiting protrusion can enter the positioning opening easily. When the limiting protrusion enters the positioning opening, the limiting protrusion limits the left-right movement of the transfer box. The limiting strip and the limiting protrusion limit the front-back movement of the transfer box, thereby realizing horizontal limiting.

[0010] In the above-mentioned loader transfer mechanism, the end of the limiting protrusion close to the limiting strip is provided with a tip portion for convenient entry into the positioning opening, and the width of the tip portion gradually increases from the end close to the limiting strip to the other end of the limiting protrusion.

[0011] In order to effectively limit the transfer box, the interior of the positioning opening has a shape that matches the tip portion, so that the limiting protrusion can perfectly match the positioning opening.

[0012] In the above-mentioned loader transfer mechanism, a guide slope is provided on the side of the limit bar close to the limit protrusion. The guide slope can guide the transfer box during installation, so that the transfer box can fall onto the transfer tray between the limit protrusion and the limit bar.

[0013] In the above-mentioned loader transfer mechanism, a bottom plate parallel to the bottom of the transfer box is fixedly connected to the bottom of the transfer box, and the positioning opening is provided on the bottom plate. An operating space is left between the bottom plate and the bottom of the transfer box to provide space for the movement of the lifting module. In order to improve the limiting effect, the height of the limiting protrusion is slightly higher than the thickness of the bottom plate.

[0014] In the above loader transfer mechanism, the base is provided with a guide rail, a slider is slidably matched on the guide rail, the transfer tray is connected to the slider, and the transfer tray is connected to the moving end of the linear module. The guide rail is parallel to the limit bar.

[0015] The driving direction of the linear module extends along the length of the guide rail. When the linear module is in motion, it will drive the transfer pallet to move along the guide rail. The linear module includes a motor, a lead screw driven by the motor, and a nut that cooperates with the lead screw thread. The transfer pallet is connected to the thread, and the nut is circumferentially limited in the linear module. When the motor rotates, the nut moves linearly.

[0016] In the above-mentioned loader transfer mechanism, the transfer pallet is provided with a plurality of transfer boxes arranged in sequence along the length direction of the guide rail, and each transfer box is correspondingly provided with a limiting protrusion.

[0017] Compared with the prior art, the loader transfer mechanism has the following advantages:

[0018] The limiting protrusion is arranged near the middle of the transfer box. When the positioning opening is not aligned with the limiting protrusion, the bottom surface of the transfer box rests on the limiting protrusion. At this time, the inclination of the transfer box can be easily observed by naked eyes, which is conducive to timely installation of the transfer box. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 1 and Figure 2 The loader transport mechanism shown is arranged below the biological sample processing device and is used to store and transport the marked loaders (sample boxes). It includes a base 1, a linear module 2 arranged on the base 1, a transfer tray 3 driven by the linear module 2 and a transfer box 4 arranged on the transfer tray 3. The transfer tray 3 is located above the linear module 2 and extends horizontally. The linear module 2 can drive the transfer tray 3 to move linearly, so as to facilitate the movement of different transfer boxes 4 to the loader entrance of the biological sample processing device.

[0024] In this embodiment, the linear module 2 includes a motor, a screw driven by the motor, and a nut matched with the screw thread. The transfer tray 3 is connected with the thread. The nut is circumferentially limited in the linear module 2. When the motor rotates, the nut moves linearly.

[0025] In order to position the transfer box 4, as Figure 2 As shown, a positioning opening 5 is provided at the bottom of the transfer box 4, and a limiting protrusion 6 is provided on the transfer tray 3 to cooperate with the positioning opening 5. The limiting protrusion 6 is arranged near the middle of the transfer box 4. When the transfer box 4 is installed in place, the limiting protrusion 6 extends into the positioning opening 5.

[0026] The limiting protrusion 6 and the positioning opening 5 work together to position the transfer box 4. When the positioning opening 5 is not aligned with the limiting protrusion 6, the bottom surface of the transfer box 4 rests on the limiting protrusion 6. At this time, the contact point between the bottom of the transfer box 4 and the upper surface of the transfer pallet 3 is the first point, and the contact point between the bottom of the transfer box 4 and the upper surface of the limiting protrusion 6 is the second point. The line connecting the first point and the second point is assumed to be the hypotenuse of the triangle, and the limiting protrusion 6 is the height of the triangle. The closer the limiting protrusion 6 is to the first point, the more inclined the hypotenuse of the triangle is, and the more inclined the transfer box 4 is, which is convenient for direct observation with the naked eye and is conducive to timely installation of the transfer box 4.

[0027] In this embodiment, Figure 2 As shown, one side edge of the bottom of the transfer box 4 is recessed toward the middle to form a positioning opening 5, and a limiting strip 7 is provided on the transfer tray 3, and the limiting strip 7 extends in a direction perpendicular to the recessed direction of the positioning opening 5, and the installed transfer box 4 is horizontally limited between the limiting protrusion 6 and the limiting strip 7. The positioning opening 5 is designed to be open, so that the limiting protrusion 6 can enter the positioning opening 5 conveniently. When the limiting protrusion 6 enters the positioning opening 5, the limiting protrusion 6 limits the left-right movement of the transfer box 4, and the limiting strip 7 and the limiting protrusion 6 limit the front-back movement of the transfer box 4, so as to achieve horizontal limitation.

[0028] like Figure 2 As shown, the end of the limiting protrusion 6 close to the limiting strip 7 is provided with a tip portion 61 for convenient entry into the positioning opening 5, and the width of the tip portion 61 gradually increases from the end close to the limiting strip 7 to the other end of the limiting protrusion 6. In order to effectively limit the transfer box 4, the interior of the positioning opening 5 has a shape that matches the tip portion 61, so that the limiting protrusion 6 can perfectly match the positioning opening 5.

[0029] like Figure 2 As shown, a guide slope 71 is provided on one side of the limit strip 7 close to the limit protrusion 6. The guide slope 71 can guide the transfer box 4 during installation, so that the transfer box 4 can fall onto the transfer tray 3 between the limit protrusion 6 and the limit strip 7.

[0030] In this embodiment, Figure 1 and Figure 2As shown, a bottom plate 41 parallel to the bottom of the transfer box 4 is fixedly connected to the bottom of the transfer box 4, and a positioning opening 5 is provided on the bottom plate 41. An operating space is left between the bottom plate 41 and the bottom of the transfer box 4 to provide space for the movement of the lifting module. In order to improve the limiting effect, the height of the limiting protrusion 6 is slightly higher than the thickness of the bottom plate 41.

[0031] In order to ensure the smooth movement, Figure 1 and Figure 2 As shown, a guide rail 8 is provided on the base 1, and a slider 9 is slidably fitted on the guide rail 8. The transfer tray 3 is connected to the slider 9, and the transfer tray 3 is connected to the moving end of the linear module 2, and the guide rail 8 is parallel to the limit bar 7.

[0032] In this embodiment, three transfer boxes 4 are arranged in sequence along the length direction of the guide rail 8 on the transfer pallet 3, and each transfer box 4 is correspondingly provided with a limiting protrusion 6.

[0033] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
