If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
Referring to fig. 1 to 2, the device for taking and placing the reaction cup 40 in the embodiment of the present invention includes a base 10, a clamping portion 20, and an elastic member, wherein the base 10 is provided with a mounting groove 11 for mounting the reaction cup 40, a first end of the clamping portion 20 is hinged to the base 10, a second end of the clamping portion 20 can move away from or close to the mounting groove 11 during rotation around the hinge, the elastic member connects the base 10 and the clamping portion 20, and the elastic member is used for applying an elastic force close to the mounting groove 11 to the clamping portion 20. The clamping portion 20 is rotated to make the second end of the clamping portion 20 far away from the mounting groove 11, so as to facilitate the reaction cup 40 to be installed in the mounting groove 11, and then the clamping portion 20 is rotated under the elastic force of the elastic member and approaches the mounting groove 11, so as to clamp the reaction cup 40 in the mounting groove 11, thereby preventing the reaction cup 40 from being released from the present invention, and the elastic member can ensure that the reaction cup 40 is stably clamped in the mounting groove 11 all the time without consuming energy.
It can be understood that the width of the mounting groove 11 is larger than the diameter of the body of the reaction cup 40 and smaller than the diameter of the ear of the reaction cup 40, so as to accommodate the body of the reaction cup 40 and prevent the reaction cup 40 from falling off. The mounting groove 11 has a side opening through which the reaction cup 40 enters and exits the mounting groove 11. As an alternative embodiment, the second end of the clamping part 20 is located at one side of the side opening of the mounting groove 11, and the elastic member applies a horizontal elastic force to the clamping part 20, so as to press the reaction cup 40 in the mounting groove 11 and prevent the reaction cup 40 from falling out of the side opening. As another alternative, in this embodiment, the second end of the clamping portion 20 is located above the mounting groove 11, and the clamping portion 20 presses the cup ears of the reaction cups 40 against the top surface of the mounting groove 11 under the action of the elastic member. Since the clamping part 20 is not movable at the side opening, the reaction cups 40 are not usually blocked from entering and exiting the mounting groove 11 when the reaction cups 40 are taken and placed, and the required operation space is smaller.
Further, the second end of the clamping portion 20 is provided with a clamping member 21, and the width of the clamping member 21 is gradually reduced from top to bottom. In the present application, the width of the holding member 21 refers to the maximum value of the distance between any two points of the holding member 21 in the horizontal cross section. In this embodiment, the clamping member 21 is a strip shape, and the clamping member 21 is bent to form a V-shape with an upward opening, so as to ensure that the clamping member 21 can at least partially pass through the mounting groove 11 when the second end of the clamping portion 20 is approaching the mounting groove 11, thereby preventing the reaction cup 40 from being pulled out from the side opening.
As can be appreciated, the clamping portion 20 is hinged to the base 10 by a pivot 31. As an alternative embodiment, the elastic member is a telescopic spring, two ends of the telescopic spring are respectively connected with the base 10 and the clamping portion 20, when the clamping portion 20 rotates to be away from the mounting groove 11, the telescopic spring is stretched, and when the clamping portion 20 is reset, the telescopic spring contracts and returns to an initial state. Since the joint between the extension spring and the holder 20 does not move in a pure straight line when the holder 20 rotates, the extension spring is deformed during the extension and retraction process. As another alternative, in this embodiment, the elastic member is a torsion spring 30, one end of the torsion spring 30 is connected to the base 10, and the other end of the torsion spring 30 is connected to the clamping portion 20. Further, the torsion spring 30 is sleeved on the rotating shaft 31, so that the position of the torsion spring 30 cannot be greatly deviated, and the structure is not easy to deform.
The bottom surface of the clamping part 20 is provided with a top column 22, the base 10 is provided with a base 10 opening, and the base 10 opening can be penetrated by the top column 22. In the initial state, the clamping portion 20 is forced by the elastic member, and the top pillar 22 passes through the opening of the base 10. The base 10 drives the clamping part 20 to descend together, when the bottom end of the top column 22 contacts other equipment or a platform surface, the top column 22 is jacked up, thereby driving the clamping part 20 to overcome the elasticity of the elastic part, and the clamping part 21 is far away from the mounting groove 11 so that the reaction cup 40 can be loaded or unloaded. Accordingly, when the susceptor 10 is lifted, the top post 22 is again adjacent to the mounting groove 11 by the elastic member, and the clamping member 21 presses the reaction cup 40 in the mounting groove 11.
In some embodiments, the device for taking and placing the reaction cup 40 further comprises a mechanical arm, the mechanical arm comprises a gripping part, a lifting power mechanism and a rotating power mechanism, the base 10 is mounted on the gripping part, the gripping part is connected with the lifting power mechanism, and the lifting power mechanism is used for driving the gripping part to lift; the grabbing part is connected with a rotating power mechanism, and the rotating power mechanism is used for driving the grabbing part to rotate on a horizontal plane.
The working steps of the invention are as follows:
the robot arm first rotates the susceptor 10 to the reaction cup 40 placing region, and then lowers the susceptor 10 to a fixed height, and then the bottom end of the top pillar 22 contacts the instrument platform to periodically hold the part 20. The mechanical arm drives the base 10 to rotate to the position of the reaction cup 40, so that the reaction cup 40 can be accommodated in the mounting groove 11 and attached to the mounting groove 11, then the mechanical arm drives the base 10 to ascend, and the clamping part 20 fixes the reaction cup 40 in the mounting groove 11 under the action of the torsion spring 30. Finally, the mechanical arm drives the base 10 to rotate to the corresponding reactor placing area, descends again to remove the contact between the clamping part 20 and the reaction cup 40, and rotates to make the mounting groove 11 leave the reaction cup 40, so that the reaction cup 40 can be placed.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the invention as set forth in the claims appended hereto.
