A motion module for biochemical detection instrument

Abstract

This utility model discloses a motion module for a biochemical testing instrument, comprising: a mounting base, a mounting side plate fixedly mounted on one end of the mounting base, a lifting slide arm slidably mounted on one end of the inner side of the mounting side plate, and a telescopic slide block slidably mounted on one end of the inner side of the lifting slide arm; in this utility model, a stepper motor controls the rotation of a rotating lead screw, which drives the fixed lead screw sleeve screwed to it to slide up and down, thereby driving the lifting slide arm and the telescopic slide block to rise and fall. Simultaneously, during the upward and downward sliding of the fixed lead screw sleeve, the telescopic adjustment gear is connected to the fixed lead screw sleeve via a transition ring, thus controlling the rotation of the lead screw through the lead screw hole connected to the rotating lead screw while it is rising and falling. At this time, the internal rack meshing with the telescopic adjustment gear drives the telescopic slide block to synchronously slide horizontally within the lifting slide arm, thereby achieving more efficient synchronous lifting and telescopic positioning of the sample tube.

[0031] Using the above solution: the stepper motor 61 controls the rotation of the lead screw 64, which in turn drives the fixed lead screw sleeve 50 connected to it to slide up and down, thereby driving the lifting slide arm 3 and the telescopic slide 4 to rise and fall.

[0032] Reference Figure 8 The motor top plate 6 includes a top plate body 60. A stepper motor 61 is fixedly installed at one end of the top plate body 60.

[0033] The above scheme is adopted: During the sliding motion of the fixed screw sleeve 50, the telescopic adjustment gear 51 is connected to the fixed screw sleeve 50 through the adapter ring 56. Thus, the screw screw hole 55 connected to the rotating screw 64 can be used to control its rotation while it is rising and falling. At this time, the internal rack 43 meshing with the telescopic adjustment gear 51 can drive the telescopic slide 4 to move horizontally in sync inside the lifting slide arm 3. This can more efficiently realize the synchronous lifting and telescopic positioning movement of the sample tube.

[0034] The working principle of this utility model is as follows: During use, the fixed screw sleeve 50 is fixedly installed below the lifting slide arm 3 by bolts. The rotating screw 64 is rotated by the stepper motor 61, which drives the fixed screw sleeve 50 connected to it to slide up and down. This drives the lifting slide arm 3 and the telescopic slide 4 to rise and fall. At the same time, during the upward and downward sliding of the fixed screw sleeve 50, the telescopic adjustment gear 51 is connected to the fixed screw sleeve 50 through the adapter ring 56. Thus, the screw hole 55 connected to the rotating screw 64 can be controlled to rotate while it is rising and falling. At this time, the internal rack 43 meshing with the telescopic adjustment gear 51 drives the telescopic slide 4 to move horizontally inside the lifting slide arm 3 synchronously. This can more efficiently realize the synchronous lifting and telescopic positioning movement of the sample tube.
