Detailed Implementation

[0045] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figures 1 to 22As shown, a multifunctional experimental platform according to a first aspect embodiment of the present invention includes an experimental platform device 3, a pipette loading device 1, and a test tube marking device 2. Both the pipette loading device 1 and the test tube marking device 2 are mounted on the experimental platform device 3. The pipette loading device 1 is used for loading pipette tips into a box, and the test tube marking device 2 is used for marking the serial number of the test tubes.

[0047] In the above embodiments, it should be noted that the surface of the experimental table device 3 is provided with a first groove 32 and a second groove 33, and the first groove 32 and the second groove 33 are spaced apart. The pipette loading device 1 is inserted into the first groove 32, and the test tube marking device 2 is inserted into the second groove 33.

[0048] The depth of the first groove 32 is greater than the depth of the second groove 33.

[0049] The technical effect achieved by the above embodiments is that by setting both the test tube marking device 2 and the pipette loading device 1 on the experimental platform device 3, the experimental platform integrates the functions of test tube marking and automatic storage and collection of pipette tips, making operation more convenient.

[0050] Optional, such as Figures 1 to 9 As shown, in some embodiments, the pipette loading device 1 includes a housing 11, a pipette tip organizing device 12, a first sliding assembly 13, a lifting assembly 14, and a pipette loading box 15. The housing 11 is inserted into the first groove 32, and the pipette tip organizing device 12 is rotatably connected inside the housing 11. The lifting assembly 14 is installed on the first sliding assembly 13, and the pipette loading box (15) is placed on the lifting assembly 14. The pipette tip organizing device 12 is used to sort and arrange the pipette tips.

[0051] The gun head positioning device 12 includes a first motor 1211, a rotating rod 1201, multiple rotating slide rods 1210, a cover plate 1206, a support rod 1204, and a first baffle 1207. The first motor 1211 is installed on the outer side wall of the housing 11. The rotating rod 1201 passes through the housing 11 and is connected to the output shaft of the first motor 1211. One end of each rotating slide rod 1210 is rotatably connected to the rotating rod 1201, and the other end of each rotating slide rod 1210 is located above the first sliding assembly 13. The multiple rotating slide rods 1210 are equally spaced in the radial direction of the rotating rod 1201.

[0052] The cover plate 1206 is connected to the rotating rod 1201 via the support rod 1204. The end of the cover plate 1206 away from the support plate is connected to the first baffle 1207. Multiple rotating sliding rods 1210 are located below the cover plate 1206.

[0053] The first sliding assembly 13 includes a second motor 131, a first lead screw 132, a first moving platform 133, and a first rotating block 134. The first moving platform 133 is slidably connected to the bottom of the housing 11. The second motor 131 is installed at the bottom of the housing 11. The first rotating block 134 is installed on the side wall of the housing 11. One end of the first lead screw 132 is connected to the output shaft of the second motor 131, and the other end of the first lead screw 132 is rotatably connected to the first rotating block 134. The first moving platform 133 is connected to the first lead screw 132 through a lead screw nut and is slidably disposed at the bottom of the housing 11. The lifting assembly 14 is installed on the upper surface of the first moving platform 133.

[0054] The lifting assembly 14 includes a top plate 141, a first connector 1411, a bottom plate 142, a second connector 1421, a first connecting rod 147, and a second connecting rod 149. The bottom plate 142 is mounted on the upper surface of the first moving platform 133. The second connector 1421 is provided on the bottom plate 142. One end of the first connecting rod 147 is rotatably connected to the second connector 1421. One end of the second connecting rod 149 is rotatably connected to the other end of the first connecting rod 147. The other end of the second connecting rod 149 is rotatably connected to one end of the first connector 1411. The top plate 141 is provided at the other end of the first connector 1411. The pipette cartridge 15 is mounted on the upper surface of the top plate 141.

[0055] In the above optional embodiments, it should be noted that a first controller 34 is also included, which is mounted on the surface of the experimental platform device 3; the pipette box 15 is provided with a plurality of pipette tip placement holes 16;

[0056] The pipette tip placement holes 16 are used to place pipette tips. Multiple pipette tip placement holes 16 are arranged in a rectangular array. Each row of pipette tip placement holes 16 corresponds one-to-one with the gap between two adjacent rotating slide rods 1210. The rotating slide rods 1210 can rotate clockwise or counterclockwise. The height difference between the cover plate 1206 and the rotating slide rod 1210 is half the height of the pipette tip. During operation, the first row of pipette tip placement holes 16 in the pipette holder 15 is located directly below the end of the rotating slide rod furthest from the rotating rod 1201. The rotating slide rod 1210 is in a horizontal position, and the pipette tips are scattered in the space between the cover plate 1206 and the housing 11. Some pipette tips are located... On the rotating slide bar 1210, some gun heads are located between two adjacent rotating slide bars 1210. Since the shape of the gun head is conical, the rotation of the rotating slide bar 1210 allows the gun heads to roll into the gap between the rotating slide bars 1210 with the larger end on top and the smaller end on the bottom. Then, by rotating the rotating rod 1201 to tilt the rotating slide bar 1210, the gun heads slide down from top to bottom. The cover plate 1206 prevents the gun heads from scattering elsewhere when they slide down. When the gun head slides to the end of the rotating slide bar 1210 away from the rotating rod 1201, it can fall into the corresponding gun head placement hole 16. In this way, a row of gun heads can be loaded at one time. The first moving platform 133 moves back and forth, driving the lifting component 14 to move. The lifting component 14, which carries the pipette box 15, moves up and down to achieve the arrangement and boxing of pipette tips. The first baffle 1207 can prevent the second row of pipette tips from falling directly after the first row of pipette tips is boxed due to the interference of the large head at the top of the first row of pipette tips. The first baffle 1207 can also prevent the second row of pipette tips from falling directly to another place. The coordinated arrangement of the first baffle 1207, cover plate 1206, inclined rotating slide bar 1210, lifting component 14 and first moving platform 133 can ensure that the second row of pipette tips falls smoothly into the second row of pipette tip placement hole 16.

[0057] The housing 11 includes a bottom panel 111 and a side panel 112. The side panel 112 is mounted on the upper surface of the bottom panel 111. The rotating rod 1201 is rotatably connected to the side panel 112. The first moving stage 133 is mounted on the bottom panel 112. There are three side panels 112. The three side panels 112 are connected to the bottom panel 111 by welding or bolting. The width of the first moving stage 133 is equal to the width of the receiving cavity of the housing 11. The lifting assembly 14 is connected to the first moving stage 133 by bolting or snap-fitting. The pipette cartridge 15 is snap-fitted to the top plate 141.

[0058] The gun head positioning device 12 also includes a rotating shaft 1203, a reinforcing plate 1205, a second baffle 1208, multiple placement blocks 1209, and multiple slide bar motors 1212;

[0059] The end of the cover plate 1206 away from the first baffle 1207 is connected to the second baffle 208. The second baffle 208 and the cover plate 1206 are perpendicular to each other. When the rotating slide rod 1210 is in a horizontal state, the top surface of the second baffle 208 is flush with the top surface of the housing 11. During operation, the disordered gun heads are scattered in the space between the second baffle 208 and the housing 11.

[0060] Multiple slide bar motors 1212 are connected to the rotating rod 1201, and multiple rotating slide bars 1210 pass through the rotating rod 1201 and are connected to the output shafts of the multiple slide bar motors 1212 in a one-to-one correspondence. The slide bar motors 1212 and the rotating shaft 201 are connected by a motor bracket or directly by bolts. The output shafts of the slide bar motors 1212 and the rotating slide bars 1210 are connected by a coupling.

[0061] Multiple placement blocks 209 are all disposed at the end of the cover plate 1206 away from the support rod 204, and the placement blocks 209 are disposed in a one-to-one correspondence with the rotating slide rod 1210. The width of the placement block 209 is equal to the diameter of the rotating slide rod 1210.

[0062] Both ends of the rotating rod 1201 are integrally formed with rotating shafts 1203. The rotating rod 1201 is rotatably connected to the housing 11 through the rotating shafts 1203. The first motor 1211 is connected to one of the rotating shafts 1203 through a coupling. The first motor 1211 is connected to the housing 11 through bolts or a motor bracket.

[0063] A reinforcing plate 1205 is provided on each side of the cover plate 1206, and the cover plate 1206, the reinforcing plate 1205 and the support rod 1204 are integrally formed.

[0064] The lifting assembly 14 also includes two connecting rods 143, a worm threaded portion 144, a third motor 145, two worm gear blocks 146, and a worm shaft body portion 148.

The four second connecting members 1421 are arranged in a matrix on the base plate 142, and the four first connecting members 1411 are arranged in a matrix on the top plate 141. One end of each of the four first connecting rods 147 is rotatably connected to one of the four second connecting members 1421. The four second connecting rods 149... Each of the four first connecting rods 147 is rotatably connected to one of the four first connecting rods 149, and each of the four second connecting rods 149 is rotatably connected to one of the four first connecting parts 1411. A connecting rod 143 is provided between each pair of first connecting rods 147. Two worm gear blocks 146 are provided in the middle of the connecting rod 143. One end of the worm body 148 is connected to the output shaft of the third motor 145. The third motor 145 is mounted on the base plate 142. Two worm threaded parts 144 are provided at intervals on the worm body 18. The worm gear blocks 146 and the worm threaded parts 144 are configured to cooperate with each other.

[0065] The advantages of the above optional embodiments are as follows: First, the coordinated arrangement of multiple rotating slide bars 1210, rotating rods 1201, first moving stage 133, pipette box 15 and cover plate 1206 can ensure rapid boxing of pipette tips, greatly increasing the boxing speed of pipette tips and realizing rapid boxing of pipette tips.

[0066] Secondly, the placement speed of the pipette tip can be increased by setting the second baffle 208.

[0067] Third, the sliding rod motor 1212 provides power for the rotation of the sliding rod 1210.

[0068] Fourth, the setting of multiple placement blocks 209 can restrict the front and rear direction of the gun head, further ensuring the reliability of the gun head falling into the gun head box.

[0069] Fifth, the strength and reliability of the cover plate 1206 can be guaranteed by the setting of the reinforcing plate 1205.

[0087] Telescopic rod 224 is an electric telescopic rod, and telescopic rod 224 is electrically connected to the second controller 35;

[0088] The working principle of the test tube marking device 2 is as follows: when it is necessary to mark the test tubes with serial numbers, firstly, the second controller 35 controls the fifth motor 241 to drive the second lead screw 243 to rotate, thereby driving the second moving stage 242 to move directly below the moving plate assembly 222.

[0089] Then, the second controller 35 controls the telescopic rod 224 to descend, causing the clamping marking device 23 to move downward, so that the corresponding test tube is between the clamping rod 2323 of the clamping assembly 232 and the corresponding marking piece 2314 in the marking assembly 231.

[0090] The second controller 35 controls the fourth motor 223 to work, driving the bidirectional lead screw 221 to rotate. As the bidirectional lead screw 221 rotates, the forward thread 2212 and the reverse thread 2213 of the bidirectional lead screw 221 cooperate to drive the two adjusting blocks 2221 to move closer to each other. This, in turn, drives the clamping rod 2323 of the clamping assembly 232 and the corresponding marking element 2314 in the marking assembly 231 to move closer to each other. Thus, the mutual cooperation between the clamping rod 2323 and the marking element 2314 enables the test tube between the clamping rod 2323 and the marking element 2314 to be marked.

[0091] When the test tubes are labeled with serial numbers, the second controller 35 controls the fourth motor 223 to work, driving the bidirectional lead screw 221 to rotate. As the bidirectional lead screw 221 rotates, the forward thread 2212 and the reverse thread 2213 of the bidirectional lead screw 221 work together to drive the two adjusting blocks 2221 to move away from each other, thereby driving the clamping rod 2323 of the clamping assembly 232 and the corresponding marking piece 2314 in the marking assembly 231 to move towards each other. Then, the second controller 35 controls the telescopic rod 224 to rise, driving the clamping marking device 23 to move upward to above the test tube. Then, the second controller 35 controls the fifth motor 241 to drive the second lead screw 243 to rotate, thereby driving the second moving stage 242 to move out.

[0092] The advantages of the above optional embodiments are: by coordinating the adjustment component 22, the telescopic rod component, the marker 2314 and the multiple clamping rods 2323, multiple test tubes can be marked with corresponding serial numbers at the same time, which improves work efficiency.

[0093] Optional, such as Figures 1 to 3 As shown, in some embodiments, a first controller 34 and a second controller 35 are also included. Both the first controller 34 and the second controller 35 are mounted on the surface of the experimental platform device 3. The first controller 34 is electrically connected to the pipette loading device 1, and the second controller 35 is electrically connected to the test tube marking device 2.
