[0032] Referring to Figures 1 to 9 The application provides a driving module 10 for a reagent processing device.

[0033] The driving module 10 comprises a support frame 100, a rotating frame 200, a lubricating stabilizer 300, a movable rod 400, a first driving assembly 500 and a second driving assembly 600. The rotating frame 200 is rotatably installed on the support frame 100. The lubricating stabilizer 300 is installed on the support frame 100 or the rotating frame 200 and is formed with a through hole 310. The movable rod 400 is arranged in the through hole 310 and abuts against the lubricating stabilizer 300. One end of the movable rod 400 is movably installed on the rotating frame 200 in the vertical direction. The first driving assembly 500 is installed on the support frame 100 and is in transmission connection with the rotating frame 200. The first driving assembly 500 is used to drive the rotating frame 200 to rotate in the horizontal direction, so as to drive the movable rod 400 to rotate in the horizontal direction. The second driving assembly 600 is installed on the support frame 100 or the rotating frame 200 and is connected with the movable rod 400. The second driving assembly 600 is used to drive the movable rod 400 to move in the vertical direction. Compared with the prior art, the driving module 10 provided by the application installs the lubricating stabilizer 300 on the support frame 100 or the rotating frame 200, arranges the movable rod 400 in the through hole 310 formed by the lubricating stabilizer 300, and restrains the movable rod 400 after the lubricating stabilizer 300 abuts against the movable rod 400, so as to limit the movable rod 400 from shaking in the horizontal direction, so that the movable rod 400 is relatively stable during rotation or lifting. That is, the lubricating stabilizer 300 can provide lubrication and guidance for the movable rod 400 during the movement of the movable rod 400, so as to avoid abrasion between the movable rod 400 and the support frame 100 or the rotating frame 200, thereby improving the service life of the driving module 10.

[0034] As shown in Figure 1 and Figure 6 The support frame 100 comprises a bottom plate 110, side plates 120, a top plate 130 and a mounting table 140. The side plates 120 are connected with the bottom plate 110 and the top plate 130 respectively. The bottom plate 110 and the top plate 130 are oppositely and spacedly arranged.

[0035] Optionally, the top plate 130 is formed with a mounting hole 131, the mounting table 140 has an inverted convex shape in a vertical direction, and the mounting table 140 is mounted on the top plate 130 by rivets or screws, and the mounting table 140 is partially accommodated in the mounting hole 131. It should be noted that in other embodiments, the mounting table 140 can also be clamped on the top plate 130, such as the mounting table 140 being provided with a first clamping part, and the top plate 130 being provided with a second clamping part matched with the first clamping part, one of the first clamping part and the second clamping part being a clamping column, and the other of the first clamping part and the second clamping part being a clamping slot.

[0036] Further, the mounting table 140 is formed with a mounting groove 141, and the mounting table 140 is formed with a through hole 142 at the groove bottom of the mounting groove 141, the mounting groove 141 and the through hole 142 both have a circular cross section in a horizontal direction and are coaxially arranged, and the cross-sectional area of the mounting groove 141 in the horizontal direction is greater than the cross-sectional area of the through hole 142 in the horizontal direction.

[0037] It can be understood that in the production process, the bottom plate 110, the side plate 120, the top plate 130 and the mounting table 140 can be integrally formed to omit the assembly steps of the bottom plate 110, the side plate 120, the top plate 130 and the mounting table 140, thereby improving the production efficiency.

[0038] It should be noted that in other embodiments, the support frame 100 can also only include the bottom plate 110, the rotating frame 200 is rotatably mounted on the bottom plate 110, the lubricating stabilizing piece 300 is fixedly mounted on the rotating frame 200, the movable rod 400 is arranged through the via hole 310 and abuts against the lubricating stabilizing piece 300, and one end of the movable rod 400 is movably mounted on the rotating frame 200; the first driving assembly 500 is mounted on the bottom plate 110 and is in transmission connection with the rotating frame 200 to drive the rotating frame 200 to rotate in the horizontal direction; and the second driving assembly 600 is mounted on the rotating frame 200 and is connected with the movable rod 400 to drive the movable rod 400 to move in the vertical direction.

[0039] Optionally, as shown in Figures 1 to 3 The rotating frame 200 includes a rotating disc 210 and a secondary support 220, the rotating disc 210 is rotatably mounted on the mounting table 140; one end of the secondary support 220 is fixedly mounted on the side of the rotating disc 210 away from the mounting table 140, and the other end of the secondary support 220 is suspended as a free end or is rotatably mounted on the bottom plate 110, so that the rotating disc 210 can drive the secondary support 220 to rotate in the process of rotation. It can be understood that in the production process, the rotating disc 210 and the secondary support 220 can be integrally formed to omit the assembly steps of the rotating disc 210 and the secondary support 220, thereby improving the production efficiency.

[0040] Exemplarily, as shown in Figure 3 andFigure 7 As shown in the figure, the rotating disc 210 comprises a bottom wall 211, an inner ring wall 212 and an outer ring wall 213. The bottom wall 211 is formed with an avoiding hole 2111, and the cross-sectional area of the avoiding hole 2111 in the horizontal direction is greater than that of the through hole 310 in the horizontal direction, so that the movable rod 400 does not directly contact the rotating disc 210. The inner ring wall 212 is connected to the outer edge of the avoiding hole 2111, and the outer ring wall 213 is connected to the outer edge of the bottom wall 211, and the outer ring wall 213 is spaced and arranged outside the inner ring wall 212.

[0041] Further, as shown in the figure, Figures 3 to 5 The rotating disc 210 further comprises a first induction piece 214 connected to the outer edge of the bottom wall 211, and the driving module 10 further comprises a first induction switch 180 mounted on the side plate 120 and matched with the first induction piece 214, for controlling the first driving assembly 500 to work. The first induction piece 214 is a sector-shaped induction sheet. When the first induction switch 180 senses the first induction piece 214, i.e. the first induction switch 180 is opposite to the first induction piece 214, the first induction switch 180 is in an open state, thereby controlling the first driving assembly 500 to start working. When the rotating disc 210 rotates to a certain angle, the first induction switch 180 cannot sense the first induction piece 214, i.e. the first induction switch 180 is misaligned with the first induction piece 214, and the first induction switch 180 is in a closed state, thereby controlling the first driving assembly 500 to stop working. It should be noted that in other embodiments, the first induction switch 180 can also be a sensor.

[0042] Optionally, as shown in the figure, Figures 1 to 3 The auxiliary support 220 comprises a bottom connecting plate 221, a side connecting plate 222 and a top connecting plate 223. The side connecting plate 222 is connected with the bottom connecting plate 221 and the top connecting plate 223 respectively, and the bottom connecting plate 221 and the top connecting plate 223 are oppositely and spacedly arranged. The bottom connecting plate 221 is rotatably mounted on the bottom plate 110, and the top connecting plate 223 is clamped on or mounted on the side of the bottom wall 211 away from the inner ring wall 212 by rivets or screws. It should be noted that in other embodiments, the auxiliary support 220 can also not comprise the bottom connecting plate 221, i.e. the end of the auxiliary support 220 away from the rotating disc 210 is a free end. In this way, the step of mounting the bottom connecting plate 221 to the bottom plate 110 can be omitted, the production efficiency is improved, and the number of parts required for installation is reduced, thereby reducing the production cost.

[0043] It can be understood that in the embodiment in which the support frame 100 only comprises the bottom plate 110, the rotating disc 210 is mounted on the bottom plate 110, the bottom connecting plate 221 is mounted on the side of the rotating disc 210 away from the bottom plate 110, the lubricating stabilizing member 300 is mounted on the top connecting plate 223, and the second driving assembly 600 is mounted on the rotating disc 210 or the side connecting plate 222.

[0044] Optionally, as shown in Figure 2 and Figure 3 , the driving module 10 further comprises a bearing 700, the bearing 700 is arranged in the mounting groove 141, and the outer ring of the bearing 700 is connected to the mounting table 140, for example, the outer ring of the bearing 700 is bonded to or clamped to the mounting table 140 or the outer ring of the bearing 700 is in interference fit with the mounting groove 141; the inner ring of the bearing 700 is connected to the inner ring wall 212, for example, the inner ring of the bearing 700 is bonded to or clamped to the inner ring wall 212 or the inner ring wall 212 is in interference fit with the inner ring of the bearing 700. Compared with the direct rotating connection between the mounting table 140 and the rotating disc 210, the bearing 700 arranged between the mounting table 140 and the rotating disc 210 can make the rotating disc 210 more easily rotate relative to the mounting table 140, thereby reducing wear and energy consumption. It should be noted that in other embodiments, the inner ring of the bearing 700 can also be connected to the mounting table 140, and the outer ring of the bearing 700 is connected to the outer ring wall 213.

[0045] Optionally, as shown in Figure 2 and Figure 3 , the driving module 10 further comprises a fastener 800, the lubricating stabilizing member 300 is mounted on the side of the inner ring wall 212 away from the bottom wall 211 through the fastener 800, and the fastener 800 can be a rivet or a screw. It can be understood that in other embodiments, the lubricating stabilizing member 300 can also be clamped to the side of the inner ring wall 212 away from the bottom wall 211; or the lubricating stabilizing member 300 can also be mounted on the bottom wall 211; or the lubricating stabilizing member 300 can also be mounted on the top connecting plate 223.

[0046] Further, as shown in Figure 3 and Figure 7 , the inner ring wall 212 is provided with a limiting portion 2121, the limiting portion 2121 abuts against the bottom of the inner ring of the bearing 700, and after the lubricating stabilizing member 300 is mounted on the side of the inner ring wall 212 away from the bottom wall 211, it is pressed against the top of the inner ring of the bearing 700, so that the inner ring of the bearing 700 is clamped between the limiting portion 2121 and the lubricating stabilizing member 300, which can make the inner ring of the bearing 700 more stably connected to the inner ring wall 212.

[0047] Further, as shown in Figure 3 and Figure 6As shown, the mounting table 140 is formed with a receiving groove 143 on the side wall of the mounting groove 141, the receiving groove 143 is annular, and the drive module 10 further comprises a crimping strip 900 arranged in the receiving groove 143 and pressed on the top of the outer ring of the bearing 700, so that the outer ring of the bearing 700 is clamped between the crimping strip 900 and the groove bottom of the mounting groove 141, and the outer ring of the bearing 700 is more stably connected to the mounting table 140. The crimping strip 900 is elastic and has an annular structure without connection between the head and the tail. When the crimping strip 900 is installed in the receiving groove 143, the diameter enclosed by the crimping strip 900 needs to be reduced and then put into the mounting groove 141, and then the crimping strip 900 is pressed to move to the receiving groove 143. When the crimping strip 900 is entirely arranged in the receiving groove 143, the crimping strip 900 will recover the elastic deformation.

[0048] It should be noted that in other embodiments, the lubrication stabilizing piece 300 can be clamped to the mounting table 140 or mounted to the mounting table 140 by the fastener 800. When the lubrication stabilizing piece 300 is mounted to the mounting table 140, the lubrication stabilizing piece 300 can be pressed on the top of the outer ring of the bearing 700, such as the lubrication stabilizing piece 300 is formed with a flange arranged in the mounting groove 141 and extending to the top of the outer ring of the bearing 700. In addition, the drive module 10 further comprises a crimping piece clamped to the side of the inner ring wall 212 away from the bottom wall 211 or mounted to the side of the inner ring wall 212 away from the bottom wall 211 by a rivet or a screw, and the crimping piece is pressed on the inner ring of the bearing 700. In this way, the bearing 700 can be more stably connected to the mounting table 140 and the inner ring wall 212, respectively.

[0049] Optionally, as shown in Figure 3 and Figure 9 The lubrication stabilizing piece 300 is formed with a through hole 310, the through hole 310 is in communication with the avoiding hole 2111, and the movable rod 400 is arranged in the through hole 310 and the avoiding hole 2111 and abuts against the lubrication stabilizing piece 300. The lubrication stabilizing piece 300 can not only avoid the movable rod 400 from being abraded by the mounting table 140, the rotating disc 210 and the top connecting plate 223, but also can provide lubrication and guidance for the movable rod 400 during the movement of the movable rod 400, thereby improving the service life of the drive module.

[0050] Optionally, as shown in Figures 1 to 3As shown, the movable rod 400 comprises a rod body 410 and a sliding block 420. The rod body 410 is arranged in the through hole 310 and the avoiding hole 2111 and abuts against the lubricating stabilizer 300, so that the lubricating stabilizer 300 provides lubrication and guidance for the movement of the rod body 410. The sliding block 420 is fixedly installed at one end of the rod body 410 and is slidingly connected with the two sides of the side connecting plate 222, so that the sliding block 420 can slide along the side connecting plate 222 in the vertical direction, and when the rotating disc 210 drives the sub-support 220 to rotate, the side connecting plate 222 can also drive the sliding block 420 and the rod body 410 to rotate.

[0051] Further, as shown in Figure 1 The sliding block 420 comprises a sliding block body 421 and a clamping portion 422. The sliding block body 421 is slidingly connected with the sliding rail 224, and the clamping portion 422 is fixedly installed on the side of the sliding block body 421 away from the sliding rail 224. The rod body 410 is clamped between the sliding block body 421 and the clamping portion 422, so that the sliding block 420 can drive the rod body 410 to rotate when it rotates with the side connecting plate 222. It can be understood that the end of the rod body 410 close to the sliding block 420 can be a prism, so that the rod body 410 can be more stably clamped between the sliding block body 421 and the clamping portion 422.

[0052] Further, the sub-support 220 further comprises a sliding rail 224 extending in the vertical direction and installed on the side connecting plate 222. The sliding block 420 is slidingly connected with the sliding rail 224, thereby reducing the wear of the sliding block 420.

[0053] Further, the sub-support 220 further comprises a limiting piece 225 installed on the side connecting plate 222 to limit the sliding of the sliding block 420 in the vertical direction, thereby limiting the sliding of the sliding block 420 within a certain range to improve the safety performance of the driving module 10. It should be noted that the limiting piece 225 can have multiple different installation positions in the length direction of the side connecting plate 222, so that the driving module 10 can set the limiting piece 225 according to the actual situation to adapt to test tube placement tables of different heights, thereby expanding the application range of the driving module 10.

[0054] Optionally, as shown in Figure 1 The first driving assembly 500 comprises a first driving piece 510 and a first transmission piece 520. The first driving piece 510 is fixedly installed on one end of the side plate 120 close to the top plate 130, and the first transmission piece 520 is in transmission connection with the first driving piece 510 and the outer ring wall 213 of the rotating disc 210, respectively, so that the first driving piece 510 can drive the rotating disc 210 to rotate through the first transmission piece 520. It should be noted that in the embodiment in which the support frame 100 only comprises the bottom plate 110, the first driving piece 510 needs to be installed on the bottom plate 110.

[0055] Further, the first driving member 510 is a stepper motor, a driving wheel is installed on the output shaft of the stepper motor, and the first transmission member 520 is a transmission belt, which is in transmission connection with the driving wheel and the outer ring wall 213 respectively. Of course, the driving wheel and the outer ring wall 213 can be gears, and the transmission belt is a transmission toothed belt, so that the stepper motor can more accurately control the rotation angle of the rotating disc 210.

[0056] Optionally, as shown in Figure 1 The second driving assembly 600 includes a second driving member 610, a driven wheel 620, a second transmission member 630 and a connecting member 640. The second driving member 610 is a stepper motor and is installed on one end of the side plate 120 close to the bottom plate 110. A driving wheel is installed on the output shaft of the second driving member 610. The driven wheel 620 is rotatably installed on one side of the side plate 120 close to the top plate 130. The driving wheel on the output shaft of the second driving member 610 and the driven wheel 620 are arranged in a vertical direction. The second transmission member 630 is a transmission belt and is in transmission connection with the driving wheel on the output shaft of the second driving member 610 and the driven wheel 620 respectively. One end of the connecting member 640 is rotatably installed on the rod body 410 in a horizontal direction. The other end of the connecting member 640 is movably installed on the side plate 120 in a vertical direction. The side plate 120 limits the connecting member 640 in the horizontal direction. The connecting member 640 is in fixed connection or transmission connection with the second transmission member 630. When the second driving member 610 drives the second transmission member 630 to move in a vertical direction, the second transmission member 630 can drive the connecting member 640 to move in a vertical direction, and the rod body 410 and the sliding block 420 move in a vertical direction along with the connecting member 640. When the first driving member 510 drives the rotating disc 210 to rotate through the first transmission member 520, the rotating disc 210 drives the sub-support 220, the rod body 410 and the sliding block 420 to rotate relative to the support frame 100 and the connecting member 640. It should be noted that in the embodiment in which the support frame 100 only includes the bottom plate 110, the second driving member 610, the driven wheel 620 and the connecting member 640 need to be installed on the side connecting plate 222 of the sub-support 220. One end of the connecting member 640 is in fixed connection with the rod body 410 or the sliding block 420, and the other end of the connecting member 640 is in fixed connection or transmission connection with the second transmission member 630.

[0057] Further, as shown in Figure 1 and Figure 8As shown, the connecting member 640 comprises a first sub-connecting member 641 and a second sub-connecting member 642 fixedly installed on the first sub-connecting member 641, and the first sub-connecting member 641 and the second sub-connecting member 642 are substantially L-shaped and rotatably installed on the rod body 410 through bearings. The first sub-connecting member 641 is formed with a guide column 6411, and the side plate 120 of the support frame 100 is formed with a guide groove 121 matched with the guide column 6411, and the extension direction of the guide groove 121 is parallel to the vertical direction, so that the connecting member 640 can drive the rod body 410 and the sliding block 420 to move in the vertical direction. The second sub-connecting member 642 is formed with a connecting piece 6421, and the connecting piece 6421 is fixedly connected or drivingly connected with the second transmission member 630, so that the connecting member 640 can move in the vertical direction along with the second transmission member 630.

[0058] Further, the driving module 10 further comprises a second sensing member 6422 installed on the second sub-connecting member 642 and a second sensing switch 190 installed on the side plate 120 and matched with the second sensing member 6422, for controlling the second driving member 610 to work. The second sensing member 6422 is a substantially Z-shaped sensing piece, when the second sensing switch 190 senses the second sensing member 6422, i.e. the second sensing switch 190 is opposite to the second sensing member 6422, the second sensing switch 190 is in an open state, thereby controlling the second driving member 610 to start working, when the second sub-connecting member 642 moves a certain distance, the second sensing switch 190 cannot sense the second sensing member 6422, i.e. the second sensing switch 190 is misaligned with the second sensing member 6422, the second sensing switch 190 is in a closed state, thereby controlling the second driving member 610 to stop working. It can be understood that in other embodiments, the second sensing member 6422 can be installed on the rod body 410 or the sliding block 420, and the second sensing switch 190 is installed on the side connecting plate 222. It should be noted that in other embodiments, the second sensing switch 190 can also be a sensor.

[0059] It should be noted that in other embodiments, the second driving assembly 600 can only comprise the second driving member 610, and the second driving member 610 is a pneumatic cylinder or a hydraulic cylinder, which is installed on the bottom connecting plate 221 or the side connecting plate 222 of the sub-support 220 and connected with the rod body 410 or the sliding block 420, so as to drive the rod body 410 and the sliding block 420 to move in the vertical direction. Alternatively, the second driving assembly 600 can only comprise the second driving member 610 and the connecting member 640, and the second driving member 610 is a pneumatic cylinder or a hydraulic cylinder, which is installed on the side plate 120 and connected with the connecting member 640, so that the second driving member 610 can drive the rod body 410 and the sliding block 420 to move in the vertical direction through the connecting member 640.

[0060] The application also provides a reagent processing device, which comprises the operation module and the driving module 10 as described above.

[0061] The above only describes some embodiments of the application, and does not limit the protection scope of the application, and any equivalent device or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the application.
