Attached Figure Description
[0012] Figure 1 This is a perspective view of the automatic loading device provided in an embodiment of the present invention. Detailed Implementation
[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0014] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0015] like Figure 1 As shown, the automatic sample filling device for testing equipment provided by this utility model includes a transfer device 10 for transferring samples from the sample storage chamber to above the sample cup, a holding part 20 for holding the sample container, and a control device 30 for controlling the transfer device 10. In this utility model, the transfer device 10 transfers the sample from the sample storage chamber to above the sample cup, and the holding part 20 is controlled to fill the sample cup, thereby achieving automated filling.
[0016] like Figure 1As shown, the transfer device 10 includes a base 11, on which a rotating rod 12 is mounted. A rotating arm 13 is fixedly mounted at the top of the rotating rod 12. The holding part 20 is hinged to the end of the rotating arm 13 via a hinge pin 21. The transfer device 10 also includes a rotary drive device 14 for driving the rotating rod 12 to rotate. The holding part 20 includes a corner drive device 22 for controlling the rotation of the hinge pin 21. Both the rotary drive device 14 and the corner drive device 22 are controlled by the control device 30. In this embodiment, when the holding part 20 grasps the sample, the control device 30 controls the rotary drive device 14 to rotate, driving the rotating rod 12 and the rotating arm 13 to rotate, transferring the sample N above the sample cup. Then, the corner drive device 22 receives a command from the control device 30 and controls the hinge pin 21 to rotate, causing the part of the holding part 20 that holds the sample container to perform a pitching motion, thus realizing the function of tilting the sample.
[0017] like Figure 1 As shown, the other end of the hinge shaft 21 of this invention is provided with a suction cup 23 for adsorbing the sample paper bag, or the other end of the hinge shaft 21 is provided with a gripper for holding the sample container (not shown in the figure). If the sample is in a paper bag, the suction cup can be used for adsorption; if it is a container such as a cup or bowl, the gripper can be used.
[0018] like Figure 1 As shown, the automatic sample filling device of this utility model also includes a vibration device 40 that applies a vibration effect to the sample container. This vibration device 40 is controlled by the control device 30. Specifically, the vibration device 40 includes a vibration section 41 and further includes a photoelectric sensor 42 mounted on a support at the front end of the vibration section 41. The photoelectric sensor 42 is connected to the control device 30. The control device 30 includes an adjustment section 31 for controlling the amplitude and frequency of the vibration device 40. In this design, when the sample container is transported above the sample cup, it comes into contact with the vibration section 41. During the sample pouring process, the vibration section 41 applies a vibration effect to the sample container, which can accelerate the pouring speed and volume. By adjusting the adjustment section 31, when the sample volume approaches the standard quantity, the amplitude and frequency of the vibration section 41 can be reduced, facilitating more precise control of the sample quantity.
[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
