DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0024] like Figure 1 As shown, this embodiment provides a detection reagent adding device, including a turntable 3 that is rotatable around its own central axis and vertically movable, and a clamping arm arranged in a circular array around the turntable 3; wherein the clamping arm includes a clamping assembly 1 and a rotating seat 2.
[0025] Specifically, Figure 1 and Figure 2 As shown, the clamping assembly 1 includes a clamping block 11 and a bearing seat 12 which is movable along its own height direction. The bearing seat 12 is provided with a bearing groove 13, and the inner wall of the bearing groove 13 is an arc surface, which is used to cooperate with the bottom of the test tube to be clamped; a clamping hole 14 is provided through the clamping block 11, and the clamping hole 14 is circular, which matches the inner diameter of the bearing groove 13 and the central axis is coincident. More specifically, the inner diameter of the clamping hole 14 also matches the outer diameter of the test tube to be clamped, and the friction between the inner wall of the clamping hole 14 and the outer wall of the test tube is large enough to prevent the test tube from escaping from the clamping hole 14 during operation; the clamping assembly 1 is rotatably arranged in a vertical plane.
[0026] Specifically, Figure 1 and Figure 2 As shown, the rotating seat 2 includes a rotating head 21 and a rotating plate 22. The top surface of the rotating head 21 is semicircular, and it is rotatably arranged around the semicircular center axis in a vertical plane, and its bottom surface is connected to the top surface of the rotating plate 22. The bottom surface of the rotating plate 22 is connected to at least one first cylinder 23. More specifically, in this example, four first cylinders 23 are provided. The stability of the reagent adding device increases with the increase in the number of first cylinders 23, but the cost of the device is also higher; the clamping assembly 1 is rotatably connected to the driving shaft of the first cylinder 23, so that when the clamping assembly 1 rotates, the driving shaft of the first cylinder 23 will not rotate with it, but is only driven by the rotation of the rotating head 21.
[0027] During operation, the reagent to be added is placed in the test tube, and the test tube is passed through the clamping hole 14 so that its bottom contacts and cooperates with the carrying groove 13; the turntable 3 is raised and lowered to a suitable position, and the turntable 3 is rotated to move the clamping wall to the direction of the reaction pool, the rotating head 21 is rotated and the first cylinder 23 is started to drive the test tube to move to the top of the reaction pool, and the clamping assembly 1 is rotated at this time so that the opening of the test tube faces downward, and the reagent inside it enters the reaction pool to complete the reagent addition; when adding multiple reagents at one time, multiple test tubes need to be installed on multiple clamping arms respectively, and the turntable 3, the rotating head 21, the first cylinder 23, and the clamping assembly 1 are repeatedly driven after each single reagent is added.
[0028] Preferably, Figure 1 and Figure 2 As shown, the device also includes a driving block 15, which is in a rectangular shape and has two mounting grooves at both ends. A first rotating motor 16 is provided in each mounting groove. The two first rotating motors 16 are respectively connected to a first cylindrical sleeve 17 in the mounting groove, and the first sleeve 17 is rotatably connected to the wall of the mounting groove; a second cylindrical sleeve 18 is respectively connected to both sides of the clamping block 11, and a rotating belt 19 is rotatably sleeved on the first sleeve 17 and the second sleeve 18 that match each other. Specifically, the rotating axis of the clamping assembly 1 is arranged to coincide with the rotating axis of the second sleeve 18; the driving block 15 is also connected to two supporting plates 110, and the second sleeve 18 is rotatably inserted into an opening on the supporting plate 110, and the supporting plate 110 is used to connect the driving block 15 and the clamping assembly 1 and support the clamping assembly 1 to maintain the relative position of the driving block 15 and the supporting assembly 1.
[0029] Preferably, Figure 1 and Figure 2 As shown, the driving shaft of the first cylinder 23 is connected to the driving block 15, and is used to drive the driving block 15 to move in its length direction, thereby driving the clamping assembly 1 to move.
[0030] Preferably, as 2 and Figure 3As shown, a round rod-shaped slide bar 111 is vertically provided on the upper surface of the supporting seat 12, and a circular slide hole 112 and an elastic seam 113 are also penetrated in the clamping block 11. The slide bar 111 is slidably penetrated in the slide hole 112 to control the distance between the supporting seat 12 and the clamping block 11 so as to place test tubes of different lengths and models; further preferably, the slide bar 111 is provided with a limiting groove on the outer wall along its length direction, and the slide hole 112 is provided with a limiting strip on the inner wall along its depth direction, and the limiting strip is slidably matched with the limiting groove to prevent the slide bar 111 from rotating relative to each other during the sliding process. Thereby, the bearing groove 13 and the clamping hole 14 are misaligned; the tension gap 113 passes through the inner wall of the sliding hole 112 to the end of the clamping block 11 away from the clamping hole 14, and passes through from the lower end to the upper end of the clamping block 11, and the width of the tension gap 113 is adjustable, which is used to control the movement of the sliding rod 111 in the sliding hole 112. When the tension gap 113 is small enough, the inner diameter of the sliding hole 112 becomes smaller, and the friction between its inner wall and the sliding rod 111 increases, at this time, the movement of the sliding rod 111 can be locked; further preferably, in this example, the width of the tension gap 113 is controlled by bolt matching.
[0031] Preferably, Figure 1 , Figure 2 , Figure 4 As shown, there are multiple second rotating motors 31 in a circular array on the side of the turntable 3, and the number of the second rotating motors 31 matches the clamping arm. The rotating shaft of the second rotating motor 31 is connected to the rotating head 21 to drive the rotating head 21 to rotate. Further preferably, in this example, each clamping wall is matched with two second rotating motors 31, and the second rotating motors 31 are respectively arranged on both sides of the rotating head 21.
[0032] Preferably, Figure 1 and Figure 4 As shown, the bottom surface of the turntable 3 is connected to the rotating shaft of a third rotating motor 32, and the third rotating motor 32 is arranged in a cylindrical rotating bin 33, which is used to drive the turntable 3 to rotate; the top of the rotating bin 33 is slidably fitted with the turntable 3, which is used to support the turntable 3 and share the supporting pressure of the third rotating motor 32; the bottom of the rotating bin 33 is connected to the driving shaft of a vertically arranged second cylinder 34, and the second cylinder 34 is installed on a base 35, which is used to drive the turntable 3 to rise and fall.
[0033] During operation, the base 35 is first installed to a suitable position, and then the second cylinder 34 is started to lift the turntable 3 to a height suitable for placing the test tube on the clamping arm. When placing the test tube, the slide bar 111 is moved in the slide hole 112 to clamp test tubes of different heights and models; the third rotating motor 32 is started to place the test tubes containing the reagents to be added on the clamping assembly 1 in turn. After the placement is completed, the second cylinder 34 is started to lift the turntable 3 to a height suitable for adding the reagents; when adding different reagents in turn, different clamping arms need to be driven by the third rotating motor 32. It stays at the appropriate reagent adding position in sequence; when adding a single reagent, first start the second rotating motor 31, and drive the clamping arm to stay at a suitable angle by controlling the rotating head 21, and then start the first cylinder 23 to make the clamping assembly 1 stay directly above the reaction pool, and finally start the first rotating motor 16, the first rotating motor 16 drives the first sleeve head 17 to rotate, and then drives the second sleeve head 18 to rotate through the transmission of the rotating belt 19, thereby realizing the rotation of the clamping assembly 1 in the vertical plane, and driving the test tube opening to gradually rotate downward, and the reagent enters the reaction pool.
