Because the environment in the incubator is relatively dark, taking pictures directly will cause the photos to be unclear due to the brightness, and then affect the experimental results due to the deviation of the colony count. The results are biased.

In one embodiment, referring to Fig. 1 and Fig. 7-9, the gripper mechanism 3 in the mobile device for colony counting provided by the present invention specifically includes a housing 38, a third motor 32, and two gripping arms 31 and connected components. Wherein the third motor 32 is mounted on the casing 38 . The connection assembly is mounted inside the housing 38 and connected to the third motor 32 . The two clamping arms 31 respectively have a working end 311 and a connecting end 312 , the working ends 311 of the two clamping arms 31 are used to clamp the culture dish 43 , and the connecting ends 312 of the two clamping arms 31 are respectively fixed to the connection assembly. The third motor 32 drives the connection assembly to control the clamping or loosening of the two clamping arms 31 to clamp or put down the culture dish 43 .

Further, the connecting assembly includes a first connecting rod 33 , a second connecting rod 34 , a guide rail 37 , a first mounting part 35 and a second mounting part 36 .

The connecting ends 312 of the two clamping arms 31 are respectively connected to the first mounting part 35 and the second mounting part 36 . The first mounting part 35 is connected to one side of the rotation axis center of the third motor 32 through the first connecting rod 33 , and the second mounting part 36 is connected to the other side of the rotation shaft center of the third motor 32 through the second connecting rod 34 .

It works as follows:

When the third motor 32 rotates in the forward direction, the first connecting rod 33 and the second connecting rod 34 respectively drive the first mounting part 35 and the second mounting part 36 to move toward each other along the guide rail 37 so that the two clamping arms 31 are clamped.

When the third motor 32 reversely rotates, the first connecting rod 33 and the second connecting rod 34 respectively drive the first mounting part 35 and the second mounting part 36 to move in opposite directions along the guide rail 37, so that the two clamping arms 31 are loosened. open.

Optionally, referring to FIG. 17 , the first mounting part 35 and the second mounting part 36 are respectively connected to the guide rail 37 through a slide block 391, and the slide block 391 and the guide rail 37 cooperate with each other through several balls to make the clamping and clamping of the clamping arm 31 possible. The loosening action is smoother. Correspondingly, the two sides where the guide rail 37 cooperates with the slide block 391 and the two sides where the slide block 391 cooperates with the guide rail 37 are provided with arc-shaped grooves 392 that are matched with the balls.

Referring to FIG. 18 , in this embodiment, a third microswitch 30 is respectively installed on the adjacent two sides of the motor 32 , and correspondingly, on the top of the motor 32 , there is a limit rod 322 connected to the drive shaft 321 of the motor 32 , And the limit rod 322 rotates synchronously with the drive shaft 321. Of course, the limit rod 322 can touch the micro switch contacts 121 of the two third micro switches 30 during the rotation process, which are arranged on the two third micro switches 30 of the motor 32. The microswitch 30 is used to limit the rotation of the drive shaft 321 of the motor 32, so as to avoid the excessive rotation of the drive shaft from causing damage to the jaw mechanism 3 in the section of the first connecting rod 33 and the second connecting rod 34, thereby avoiding economic loss and damage to the experiment. make an impact. The principle is that the third microswitches 30 arranged on the adjacent two sides of the motor 32 jointly constitute a limit to the rotation range of the drive shaft 321, the purpose of which is to limit the range of movement of the two clamping arms 31 along the guide rail 37, so as to prevent the drive shaft from Excessive rotation results in damage to the first link 33 and the second link 34 . When the limit rod 322 touches the micro switch contact 121 with the rotation of the drive shaft 321, the third micro switch 30 feeds back to the system, and the system controls the drive shaft 321 to stop rotating, and then the two clamping arms 31 stop moving .

Further, the jaw mechanism 3 is provided with a second sensor for detecting the distance between the two clamping arms 31, so as to confirm that the two clamping arms 31 clamp the petri dish 43 before starting to move, and place the petri dish 43 from the two sides.
