FIG. 1(a) shows the three-dimensional structure of a cover body 20a; FIG. 1(b) shows the automatic opening and closing cover device 10 and its partial cross-sectional structure according to an embodiment of the present invention, and the cross-sectional structure of the cover body 20a along the line A-A . Referring to FIG. 1 and FIG. 2 together, an automatic lid opening and closing device 10 according to 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 device 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 cover body 20 a of the container 200 includes an outer cover 21 and an inner cover 22 , wherein the outer cover 21 is locked to an opening of the container 200 , and the inner cover 22 is locked to the outer cover 21 . Since the cover body 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 body, and are defined as the first cover body. 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 portions 101 a of the interference members 101 are inserted into the grooves 211 of the outer cover 21 , they interfere with each other. It can be understood that those skilled in the art to which the present invention pertains can adjust the design of the interference member 101 in accordance with the shape of the cover to interfere with the cover of the container.

The rotating shaft 102 is connected with 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 rotating shaft 102 drives the interference member 101 to rotate and also drives the outer cover 21 to rotate. In one embodiment, the interference member 101 is connected to the rotating shaft 102 in a detachable manner, so that the corresponding interference member 101 can be replaced with a cover body of different appearance. For example, the interference member 101 is fastened to the rotating shaft 102 by means of screws 101b. It should be noted that the rotating shaft 102 includes a channel 102 a, wherein a first opening of the channel 102 a faces the cover 20 a, and at least one second opening of the channel 102 a is disposed on the 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 body 20a can be adsorbed by the first opening of the channel 102a.

Referring to FIG. 1 , in one embodiment, the automatic cover opening and closing device 10 of the present invention may include a sleeve 104 , which is sleeved on the rotating shaft 102 , wherein the rotating shaft 102 is rotatable relative to the sleeve 104 . An air extraction space is defined between the sleeve 104 and the rotating shaft 102 , wherein an air extraction hole 104 a is provided on the sleeve 104 . According to the result, the air extraction space between the sleeve 104 and the rotating shaft 102 can communicate with the air extraction hole 104a on the sleeve 104 and the second opening of the channel 102a. The air extraction device 103 can be connected to the air extraction hole 104a on the sleeve 104 to perform air extraction to the channel 102a in the rotating shaft 102 .

In one embodiment, as shown in FIG. 1 , the automatic opening and closing cover device 10 of the present invention may include an annular airtight member 105 disposed around the first opening of the channel 102a. The annular airtight member 105 can abut against the cover body 20a during operation, so as to increase the airtightness between the rotating shaft 102 and the cover body 20a. In one embodiment, the annular air seal 105 is a compressible structure to increase the application range of the annular air seal 105 .

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

The lifting device 107 is connected with 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 body 20a has been separated 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 body 20a. Alternatively, 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 be close to the lid body 20a, and the interference member 101 and the lid body 20a interfere with each other.

The motor 108 is connected with the rotating shaft 102 to drive the rotating shaft 102 and the interference member 101 to rotate, thereby rotating the cover body 20a. In one embodiment, the motor 108 may be a servo motor. In one embodiment, the motor 108 may be connected to the rotating shaft 102 through a reducer 108a and a coupling 108b. The structures and functions of the reducer 108a and the coupling 108b are well known to those with ordinary knowledge 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 judge the current operating state according to the pressure change of the channel 102a output by the pressure detector 106, and then control the rotation speed or rotation direction of the motor 108 and the ascending or descending of the lifting device 107.

Referring to FIG. 2 , in one embodiment, the automatic cover 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 for capturing a positioning image of the container 200 . The controller 109 can adjust the relative positions of the interference member 101 and the lid body 20a of the container 200 through the mobile device according to the positioning image captured by the image sensor 110, so as to align the interference member 101 and the lid body 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 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 plane.

In one embodiment, the moving device includes a conveying mechanism 120 and a fixing member 121 . The conveying mechanism 120 can move the container 200 to the range of the rail 111a and the rail 111b, and the fixing member 121 can clamp the container 200 at a predetermined position. In one embodiment, the moving 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 on the container 200 . The roller 122 can drive the container 200 to rotate, so that the cover 20a of the container 200 can rotate to a predetermined position. It can be understood that, according to actual design requirements, the rail 111a, the rail 111b, the conveying mechanism 120 or the fixing member 121 can be partially omitted to achieve the effect of the mobile device.

In the embodiment shown in FIG. 1 , the cover body to be unscrewed is the outer cover 21 of the cover body 20 a , which is locked on the container 200 . Figure 3 (a) shows the three-dimensional structure of the cover body 20b; Figure 3 (b) shows the partial cross-sectional structure of the automatic opening and closing cover device according to another embodiment of the present invention, and the cross-sectional structure of the cover body 20b along the B-B line. Referring to FIG. 3 , in one embodiment, the cover to be unscrewed is the inner cover 22 (defined as the first cover here) of the cover body 20b , which is locked to the outer cover 21 (defined as the first cover here) on the second cover). Therefore, when the interference member 101 is inserted into the groove 221 of the inner lid 22 to interfere with the inner lid 22 and the inner lid 22 is rotated, the outer lid 21 may also be rotated and separated from the container 200 . In order to avoid this situation, in an embodiment, please refer to FIG. 3 , the automatic opening and closing cover device of the present invention further includes a stopper 130 , which is disposed on the radially outer side of the interference element 101 . According to this structure, when the interference member 101 interferes with the inner cover 22 and rotates, the stopper 130 abuts against the outer cover 21 and restricts the rotation of the outer cover 21 . In one embodiment, the stopper 130 may be an elastic material. For example, the stopper 130 may be a rubber material.

In one embodiment, the automatic cover opening and closing device of the present invention includes a buffer mechanism, wherein the stopper 130 is connected with 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, when the stopper 130 abuts against the outer cover 21 , the elastic element 132 will be squeezed, and the restoring force of the elastic element 132 can make the stopper 130 generate enough force to restrict the rotation of the outer cover 21 .

To sum up the above, the automatic lid opening and closing device of the present invention uses the interference member to interfere with the lid of the container, and then rotates the interference member to rotate the lid, and absorbs and removes the lid by vacuum suction. Therefore, the automatic cover opening and closing device of the present invention can open and close the cover in a mechanical and automatic manner, so as to prevent personnel from entering a high-risk work area when taking or recovering chemicals, thereby reducing the casualties of operators during industrial safety accidents .
