[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] Please refer to Figures 1-5 A specimen whole support dumping device, comprising a turnover module 1, a clamping module 2 and a test tube rack 3.

[0032] The turnover module 1 comprises a mounting plate 11, a first motor 12 is arranged on the mounting plate 11, a bearing seat 13 is further arranged on the mounting plate 11, a rotating shaft 14 is arranged on the bearing seat 13, and the first motor 12 is connected with the rotating shaft 14. The mounting plate 11 is a basic support structure of the whole turnover module 1, which provides a mounting carrier and a fixed position for other components. The first motor 12 is a power source for turnover operation. The bearing seat 13 is used for supporting the rotating shaft 14.

[0033] The clamping module 2 comprises a bottom plate 21, a first clamping arm 26 and a second clamping arm 27 which are arranged in parallel on the bottom plate 21, and the rotating shaft 14 is fixedly connected with the bottom plate 21. The bottom plate 21 is a basic component of the clamping module 2, which provides a mounting platform and a sliding track for the first clamping arm 26 and the second clamping arm 27. The main function of the first clamping arm 26 and the second clamping arm 27 is to clamp the test tube rack 3, gradually approach through opposite motion, firmly fix the test tube rack 3 in the middle, and then the first motor 12 drives the clamping module 2 clamping the test tube rack 3 to overturn the specimen in the test tube rack 3.

[0034] The first clamping arm 26 comprises a first guide rail 264 fixedly arranged on the bottom plate 21, a first sliding block 265 slidably installed on the first guide rail 264, a first connecting piece 261 fixedly installed on the first sliding block 265, and a first clamping arm 266 arranged on one side of the first connecting piece 261. The first guide rail 264 provides a sliding path and direction constraint for the first sliding block 265, ensuring that the first clamping arm 266 can stably move to clamp the test tube rack 3. The first sliding block 265 slides on the first guide rail 264 and is an intermediate component connecting the first guide rail 264 and the first connecting piece 261. It plays a role in connecting the first sliding block 265 and the first clamping arm 266, and transmits the movement of the first sliding block 265 to the first clamping arm 266. The first clamping arm 266 directly participates in the clamping operation of the test tube rack 3 and realizes the clamping function.

[0035] The second clamping arm 27 comprises a second guide rail 274 fixedly arranged on the bottom plate 21 and parallel to the first guide rail 264, a second sliding block 275 slidably installed on the second guide rail 274, a second connecting piece 271 fixedly installed on the second sliding block 275, and a second clamping arm 276 arranged on one side of the second connecting piece 271 away from the first clamping arm 266. Similarly, according to the principle of the first clamping arm 26 described above, the principle of the second clamping arm 27 is the same, and details are not repeated here.

[0036] A second motor 25 is also mounted between the first connecting member 261 and the second connecting member 271 and fixed to the bottom plate 21, and a gear 251 is arranged on the second motor 25. The second motor 25 serves as a power source to provide power for the approaching or moving away of the first clamping arm 26 and the second clamping arm 27. The gear 251 is in mesh with the first rack 263 and the second rack 273 to convert the rotary motion into the linear motion of the racks, thereby driving the first clamping arm 26 and the second clamping arm 27 to move linearly and realize the clamping and releasing operations on the test tube rack 3.

[0037] The first rack 263 and the second rack 273 are arranged in opposition on the first connecting member 261 and the second connecting member 271 respectively, and are in mesh with the gear 251. The first rack 263 and the second rack 273 are located on the two sides of the gear 251 respectively. When the gear 251 rotates, the second rack 273 will move linearly in the opposite direction of the first rack 263, thereby driving the second connecting plate and the second clamping arm 276 connected thereto to move toward the opposite direction of the first clamping arm 266, and cooperating with the first clamping arm 266 to complete the clamping and releasing operations on the test tube rack 3.

[0038] The clamping sections of the first clamping arm 266 and the second clamping arm 276 are also respectively provided with at least two first pins 262 and second pins 272. The two sides of the test tube rack 3 are respectively provided with insertion holes 31 for inserting the first pins 262 and the second pins 272. The first pins 262 and the second pins 272 cooperate with the insertion holes 31 on the test tube rack 3 to realize the accurate positioning and firm clamping of the test tube rack 3. When the first clamping arm 26 and the second clamping arm 27 move toward each other to clamp the test tube rack 3, the first pins 262 and the second pins 272 are respectively inserted into the insertion holes 31 on the two sides of the test tube rack 3 to limit the movement of the test tube rack 3 in the horizontal direction and the vertical direction, prevent it from shaking or falling during clamping, and ensure that the test tube rack 3 is stably clamped between the first clamping arm 266 and the second clamping arm 276 to provide reliable support for the subsequent overturning operation.

[0039] The sensor trigger piece 23 and the clamping sensor 24 are also arranged between the first connecting member 261 and the second connecting member 271 and fixed to the bottom plate 21. The sensor trigger piece 23 is used to determine the position of the first clamping arm 26 and the second clamping arm 27. The clamping sensor 24 is used to determine whether the first clamping arm 26 and the second clamping arm 27 clamp the test tube rack 3 and whether the next overturning operation can be continued.

[0040] The first connecting piece 261 is provided with a zero sensor 22 near one end of the first clamping arm 266. When the device is started or reset, the zero sensor 22 can help the system determine whether the first clamping arm 26 is in the initial zero position. When the device is turned on, the control system will first check the signal of the zero sensor 22. If it is detected that the first clamping arm 26 is in the zero position, it means that the distance between the first plug 262 and the second plug 272 is greater than the test tube rack 3, and at this time the clamping operation can be performed. If it is not in the zero position, the first clamping arm 26 and the second clamping arm 27 need to be reset once to make them in the zero position, so that the test tube rack 3 can be put between the first clamping arm 266 and the second clamping arm 276, thereby clamping it.

[0041] Working principle: when the turnover module 1 is in the zero position, the first clamping arm 266 and the second clamping arm 276 of the clamping module 2 are opened, and the minimum distance between the first plug 262 and the second plug 272 on the first clamping arm 266 and the second clamping arm 276 is greater than the length of the test tube rack 3. At this time, the clamping module 2 can accommodate the test tube rack 3. Then the second motor 25 rotates, the first clamping arm 266 and the second clamping arm 276 move towards each other, the distance between the first clamping arm 266 and the second clamping arm 276 gradually decreases, and the first plug 262 and the second plug 272 on the first clamping arm 266 and the second clamping arm 276 are inserted into the insertion hole 31 on the test tube rack 3. At this time, the clamping module 2 plays a restraining role on the test tube rack 3. Then the first motor 12 drives the clamping module 2 to rotate, so that the whole test tube rack 3 is turned over. When the test tube rack 3 is in the pouring state, the whole test tube rack 3 is turned over, and the test tubes fall under the action of gravity, completing the pouring. Thus, the effect of one-time automatic pouring of the whole test tube rack, unmanned and high efficiency is achieved.
