[0028] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0029] Example:

[0030] like Figure 1-Figure 5 As shown, a test tube rotating rack device includes a base 11, a side shell 12, a mechanical arm 51, a temporary placement part 30, a pitch-changing part 20 and a loading part 40, wherein the side shell 12 is arranged at the edge of the base 11; the pitch-changing part 20 is arranged in the middle of the base 11, and includes a pitch-changing slide 21 and a support block, wherein the pitch-changing slide 21 is an existing mechanism, and a plurality of sliding blocks thereon can be adjusted at equal intervals, and the support block includes a connecting piece 22 and a connecting block 23 arranged on the top of the connecting piece 22, wherein the connecting block 23 is columnar, and a connecting hole for connecting the test tube is opened in the middle, and a mounting hole is arranged on the connecting piece 22 for bolting the sliding block of the pitch-changing slide 21, and a single sliding block is connected to a single supporting block; the temporary placement part 30, the side shell 12 is arranged at the edge of the base 11; the pitch-changing part 20 is arranged in the middle of the base 11, and includes a pitch-changing slide 21 and a supporting block, and a single sliding block is connected to a single supporting block; The part 30 is arranged on one side of the variable-pitch part 20 on the base 11, and includes a temporary placement rack 31 for loading test tubes; the loading part 40 is arranged on the side of the variable-pitch part 20 on the base 11 away from the temporary placement part 30, and includes a carrier 41 and carrier strips 42 of different specifications arranged in parallel on the carrier 41, each of the carrier strips 42 is provided with a plurality of placement holes at equal intervals along the length direction, and the placement holes of the carrier strips 42 of different specifications have different spacings; the mechanical arm 51 is arranged on the base 11, and includes an arm body and a clamping claw arranged at the end of the arm body, the clamping claw includes two symmetrically arranged strip-shaped clamping plates 52, which are used to grab the test tube for transfer, and the mechanical arm 51 is an existing structure, which can realize that the two strip-shaped clamping plates 52 are close to or separated from each other.

[0031] The working principle of the above technical solution is as follows:

[0032] When the test tubes need to be transferred from the temporary rack 31 to different carrier strips 42, the existing mechanical arm 51 can be used to adjust the two strip clamps 52 to clamp the test tubes on the temporary rack 31. The quantity of test tubes in each row on the temporary rack 31 can be the same as the number of placement holes corresponding to the carrier strips 42 to be loaded with test tubes. The strip clamps 52 can clamp the test tubes in one row on the temporary rack 31 at one time. Before or while clamping, the spacing of the support blocks on the variable-pitch slide 21 is adjusted to match the spacing of the clamped test tubes, so that the mechanical arm 51 can place the clamped test tubes on the connecting block 23 at one time. After placement, the spacing of the support blocks is adjusted again by the variable pitch slide 21, so that the spacing of the test tubes on the connecting block 23 matches the spacing of the placement holes of the carrier strip 42; finally, the robot arm 51 clamps the test tubes on the connecting block 23 and places the test tubes on the corresponding carrier strip 42, wherein the length of the strip clamping block can be greater than the maximum length that the variable pitch slide 21 can adjust, to ensure that all test tubes are clamped at one time; if the test tubes on the carrier strip 42 are to be placed back on the temporary rack 31, the above steps can be performed in reverse; the action of the above-mentioned robot arm 51 and the adjustment of the variable pitch part 20 can be achieved by the control of the existing technology.

[0033] In another embodiment, if Figure 5 As shown, the inner bottom of the strip clamping plate 52 is provided with a friction pattern 53, and a clamping groove 54 is provided at the top corresponding to the friction pattern 53. The friction pattern 53 of the strip clamping plate 52 can clamp the test tube more stably, and the test tube cover can be in the clamping groove 54 when clamping the test tube.

[0034] In another embodiment, if Figure 4 As shown, a plurality of parallel rows of loading slots 43 for loading the carrier strips 42 are arranged on the carrier 41, a partition plate 44 is arranged between two adjacent loading slots, and the bottom of the carrier strips 42 is slidably connected to the loading slots. The carrier strips 42 can be slidably installed in the loading slots of the carrier 41, which can avoid lateral deviation when placing the test tubes, and facilitate the stable placement of the test tubes.

[0035] In another embodiment, if Figure 2 As shown, the temporary placement part 30 also includes a temporary placement table 32, and a slide groove is provided in the middle of the temporary placement table 32 for sliding connection with the temporary placement rack 31. One side of the slide groove is open, and the two side walls and the bottom wall of the slide groove can be respectively provided with a slide rail 33 with a roller. The temporary placement rack 31 can easily slide into the slide groove through the opening and abut against the side of the slide groove opposite to the opening, which is conducive to determining the position of the temporary placement rack 31, and the temporary placement table 32 can slide to place multiple temporary placement racks 31.

[0036] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
