Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the embodiments of the present utility model.

[0027] This embodiment provides a stable sampling mechanical gripper device, referring to... Figure 1 and Figure 3 The device includes a power unit and a gripping unit. The power unit includes a drive slide rail 6 and a drive support rod 1 that moves along the drive slide rail. The gripping unit includes an upper support arm 2 and a lower support arm 9 fixed to the bottom of the drive support rod 1. The upper support arm 2 and the lower support arm 9 are fixedly connected by a buffer spring 3. The lower support arm 9 is equipped with an electromagnet 4 for magnetically attracting a sample tray 5 with an iron sheet 10. The electromagnet 4 can be electrically connected to a controller via wiring for convenient remote control.

[0028] Reference Figure 2 The drive slide rail 6 includes a support 61 and a guide rail 62 mounted on the support 61. A sliding block 64 is provided on the guide rail 62 and moves along the guide rail 62. The drive support rod 1 is fixedly connected to the sliding block 64.

[0029] The guide rail 62 is a lead screw driven to rotate by a motor 63. The support is provided with a groove 66 parallel to the guide rail 62. The sliding block 64 is fitted onto the guide rail 62 through an internal thread. The sliding block 64 is provided with a guide block 65 that slides in the groove.

[0030] The motor 63 can be electrically connected to the controller via wiring for convenient remote control. After the motor 63 is started, the lead screw rotates. Due to the restriction of the guide block 65, the sliding block 64 does not rotate with the lead screw in the horizontal direction. Therefore, it only slides up or down along the guide rail 62 under the interaction of the threads, thereby driving the drive support rod 1 to slide up and down.

[0031] The support 61 is equipped with two photoelectric limit switches 67. When the sliding block passes the photoelectric limit switch 67, an electrical signal is generated and sent to the controller through the wire, thereby limiting the sliding range of the power component and preventing the gripping component from damaging the sample to be picked up.

[0032] The drive support rod is fixed to the slider via the adapter plate 7.

[0033] Both the upper support arm 2 and the lower support arm 9 are made of cross-shaped plates. The four ends of the two cross-shaped plates are fixedly connected by buffer springs 3. The center of the upper support arm 2 is fixedly connected to the bottom of the drive rod 1.

[0034] There are four electromagnets 4, which are evenly distributed at the four ends of the lower support arm 9.

[0035] Sample tray 5 is a square tray, and the number and distribution of iron sheets 10 correspond one-to-one with electromagnets 4.

[0036] A sensor mounting hole is provided at the center of the lower support arm 9, and the ranging sensor 8 is installed in the sensor mounting hole. The ranging sensor can be an ultrasonic ranging sensor.

[0037] The sample grasping process of the stable sampling mechanical gripper device provided in this embodiment is as follows:

[0038] When the entire stable sampling mechanical claw device is positioned directly above the sample tray 5, the motor 63 drives the guide rail 62 to rotate, causing the drive support rod 1 to move downwards. When the lower support arm 9 reaches the appropriate distance, the electromagnet 4 is energized, attracting the iron plate 10 to grasp the sample tray 5. During this process, the buffer spring 3 plays a buffering role.
