FIG. 1a shows a three-dimensional structure of a cover body 20a; FIG. 1b shows an automatic opening and closing cover device 10 and a partial cross-sectional structure of an embodiment of the present invention, and a cross-sectional structure of the cover body 20a along line AA. 1 and 2 together, an automatic opening and closing device 10 of an embodiment of the present invention includes an interference member 101, a rotating shaft 102, a pressure detector 106, a lifting device 107, a motor 108 and a control器109. The interference member 101 is used to interfere with a first cover of a container 200. In the embodiment shown in FIG. 1, the lid body 20 a of the container 200 includes an outer lid 21 and an inner lid 22, wherein the outer lid 21 is locked to an opening of the container 200, and the inner lid 22 is then locked to the outer lid 21. Since the cover to be opened or closed is the outer cover 21, the outer cover 21 and the inner cover 22 can be regarded as a single cover at this time and defined as the first cover. In the embodiment shown in FIG. 1, the interference member 101 interferes with the outer cover 21. For example, the outer cover 21 includes at least one groove 211, and the interference member 101 includes at least one protrusion 101a. When the protruding portion 101a of the interference member 101 fits into the groove 211 of the outer cover 21, they interfere with each other. It can be understood that those with ordinary knowledge in the technical field to which the present invention belongs can adjust the design of the interference member 101 in accordance with the appearance of the lid to interfere with the lid of the container.

The rotating shaft 102 is connected to the interference member 101 to drive the interference member 101 to rotate. It can be understood that, when the interference member 101 interferes with the outer cover 21, the rotation shaft 102 drives the interference member 101 to rotate, which can also drive the outer cover 21 to rotate. In an embodiment, the interference member 101 is connected to the rotating shaft 102 in a replaceable manner, so that the corresponding interference member 101 can be replaced with a cover of different appearance. For example, the interference member 101 is fixed to the rotating shaft 102 with screws 101b. It should be noted that the rotating shaft 102 includes a channel 102a, wherein a first opening of the channel 102a faces the cover 20a, and at least a second opening of the channel 102a is disposed on a side wall of the rotating shaft 102. When the air extraction device 103 is connected to the second opening of the channel 102a to perform air extraction, the pressure in the channel 102a can be reduced, and the cover 20a is absorbed by the first opening of the channel 102a.

Please refer to FIG. 1. In an embodiment, the automatic switch cover device 10 of the present invention may include a sleeve 104 which is sleeved on the rotating shaft 102, wherein the rotating shaft 102 can rotate relative to the sleeve 104. A suction space is defined between the sleeve 104 and the rotating shaft 102, wherein a suction hole 104a is provided on the sleeve 104. According to this result, the suction space between the sleeve 104 and the rotating shaft 102 can communicate with the suction hole 104a on the sleeve 104 and the second opening of the channel 102a. The air extraction device 103 is connected to the air extraction hole 104a on the sleeve 104 to evacuate the channel 102a in the rotating shaft 102.

In one embodiment, as shown in FIG. 1, the automatic opening and closing device 10 of the present invention may include an annular airtight member 105 which is disposed around the first opening of the channel 102a, so that the air between the rotating shaft 102 and the cover 20a can be increased Dense. In one embodiment, the annular airtight member 105 is a compressible structure to increase the scope of application of the annular airtight member 105.

Following the above description, the pressure detector 106 is connected between the channel 102a of the rotating shaft 102 and the suction device 103 to detect the pressure change of the channel 102a. According to the pressure change of the channel 102a, it can be judged whether the interference member 101 has moved to an appropriate position or whether the cover 20a has been adsorbed. For example, when the ring-shaped airtight member 105 contacts the cover 20a, the first opening of the channel 102a becomes a closed state, and the pressure in the channel 102a will drop rapidly when the suction device 103 continues to evacuate, so It can be known that the interference member 101 has moved to an appropriate position. Alternatively, when the interference member 101 rotates the cover 20a, the annular airtight member 105 does not contact the cover 20a. When the lid body 20a is continuously rotated to separate from the container 200, the lid body 20a is attracted due to the pressure difference, and closes the first opening of the channel 102a. When the pressure in the channel 102a is rapidly decreased, it can be known that the lid body 20a has detached from the container 200.

The lifting device 107 is connected to the interference member 101 and the rotating shaft 102 to drive the interference member 101 and the rotating shaft 102 to move in a lifting direction. For example, when the cover 20a has detached from the container 200 and is adsorbed, the lifting device 107 can drive the interference member 101 and the rotating shaft 102 away from the container 200 to remove the cover 20a. Or, when the lid is to be opened, the interference member 101 and the rotating shaft 102 are driven to move toward the container 200 to approach the lid body 20a, and the interference member 101 and the lid body 20a interfere with each other.

The motor 108 is connected to the rotating shaft 102 to drive the rotating shaft 102 and the interference member 101 to rotate, thereby rotating the cover 20a. In one embodiment, the motor 108 may be a servo motor. In one embodiment, the motor 108 can be connected to the rotating shaft 102 through a speed reducer 108a and a coupling 108b. The structure and function of the reducer 108a and the coupling 108b are well known to those of ordinary skill in the technical field to which the present invention pertains, and will not be repeated here. The controller 109 is electrically connected to the pressure detector 106, the lifting device 107, and the motor 108. The controller 109 can determine the current operating state according to the pressure change of the channel 102a output by the pressure detector 106, and then control the speed or rotation direction of the motor 108 and the rise or fall of the lifting device 107.

Please refer to FIG. 2. In one embodiment, the automatic opening and closing device 10 of the present invention includes an image sensor 110 and a mobile device, which are electrically connected to the controller 109 respectively. The image sensor 110 is used to capture a positioning image of the container 200. The controller 109 can adjust the relative position of one of the interference member 101 and the cover 20a of the container 200 through the mobile device according to the positioning image captured by the image sensor 110 to align the interference member 101 and the cover 20a. For example, the mobile device includes a track 111a and a track 111b. The interference member 101 can move left and right along the rail 111a, and in addition, the rail 111a can move back and forth along the rail 111b. According to this structure, the interference member 101 can be moved to any position parallel to the paper surface.

In one embodiment, the mobile device includes a conveying mechanism 120 and a fixing member 121. The conveying mechanism 120 can move the container 200 into the range of the rail 111a and the rail 111b, and the fixing member 121 can hold the container 200 at a predetermined position. In an embodiment, the mobile device may include at least one roller 122. For example, the roller 122 is connected to the fixing member 121, and when the fixing member 121 clamps the container 200, the roller 122 abuts the container 200. The roller 122 can drive the container 200 to rotate, so that the lid body 20a of the container 200 can be rotated to a set position. In other words, the roller 122 can rotate the container 200 to adjust the relative position of the interference member 101 and the lid body 20a. It can be understood that, by partially omitting the rail 111a, the rail 111b, the conveying mechanism 120, or the fixing member 121 according to actual design requirements, the effect of the mobile device can also be achieved.

In the embodiment shown in FIG. 1, the cover to be unscrewed is the cover 20 a and the outer cover 21, which is locked on the container 200. FIG. 3a shows the three-dimensional structure of the cover 20b; FIG. 3b shows the self-contained structure of another embodiment of the present invention. The partial cross-sectional structure of the movable switch cover device and the cross-sectional structure of the cover body 20b along the line BB. 3, in one embodiment, the cover to be unscrewed is the inner cover 22 of the cover 20b (defined as the first cover here), which is locked to the outer cover 21 (defined as the second cover here) Cover). Therefore, when the interference piece 101 is inserted into the groove 221 of the inner cover 22 and interferes with the inner cover 22 and rotates the inner cover 22, the outer cover 21 may also rotate and separate from the container 200. In order to avoid this, in an embodiment, please refer to FIG. 3, the automatic switch cover device of the present invention further includes a stopper 130, which is disposed radially outside of the interference member 101. According to this structure, when the interference member 101 interferes with the inner cover 22 and rotates, the stopper 130 abuts the outer cover 21 and restricts the outer cover 21 from rotating. In an embodiment, the stopper 130 may be an elastic material. For example, the stopper 130 may be a rubber material.

In an embodiment, the automatic switch cover device of the present invention includes a buffer mechanism, wherein the stopper 130 is connected to the buffer mechanism. According to this structure, the buffer mechanism can adaptively adjust the force of the stopper 130 against the outer cover 21. For example, the buffer mechanism includes a base 131 and at least one elastic element 132, such as a spring. The stopper 130 is disposed on the base 131. According to this structure, the stopper 130 presses the elastic element 132 when it abuts the outer cover 21, and the restoring force of the elastic element 132 can generate enough force to stop the rotation of the outer cover 21.

In summary, the automatic opening and closing device of the present invention uses an interference member to interfere with the lid of the container, and then rotates the interference member to rotate the lid, and sucks and removes the lid by vacuum suction. Therefore, the automatic lid opening and closing device of the present invention can open and close the lid in a mechanically automated manner to prevent personnel from entering high-risk work areas when taking or recovering chemical agents, thereby reducing the casualties of operators during industrial accidents .
