A powered vacuum suction cup capable of preventing displacement and self-rotation of adsorbed objects

Abstract

The present invention relates to the technical field of power vacuum suction cups, and discloses a power vacuum suction cup capable of preventing displacement and rotation of an adsorbed object, comprising a fixed column, hooks symmetrically fixedly connected to the left and right sides of the top of the fixed column, and adsorption mechanisms arranged on the left and right sides of the top of the fixed column. The object to be adsorbed is placed under four suction cups, and then the fixed column is lowered so that the four suction cups fit the surface of the object to be adsorbed. When the four suction cups contact the object to be adsorbed, they are affected by the elastic force of a first spring, which buffers the four suction cups to prevent the four suction cups from contacting the object to be adsorbed and causing damage to the four suction cups. Then, a vacuum pump is started to extract the air in the suction cup to adsorb the object to be adsorbed. After the adsorption is completed, the object to be adsorbed rises. Since four suction cups are arranged, displacement and rotation of the object to be adsorbed can be prevented when the object to be adsorbed is adsorbed.

[0014] Compared with the prior art, the present invention provides a powered vacuum suction cup that can prevent the adsorbed object from displacement and rotation, and has the following beneficial effects:

[0015] 1. The power vacuum suction cup capable of preventing displacement and self-rotation of the adsorbed object, through the adsorption mechanism, places the object to be adsorbed under four suction cups, then lowers the fixed column to make the four suction cups fit the surface of the object to be adsorbed, and when the four suction cups contact the object to be adsorbed, they will be affected by the elastic force of the first spring, so as to buffer the four suction cups, and prevent the four suction cups from being damaged by collision after contacting the object to be adsorbed, and then starts the vacuum pump to extract the air in the suction cup, and adsorbs the object to be adsorbed, and after the adsorption is completed, the object to be adsorbed rises, and since four suction cups are provided, displacement and rotation of the object to be adsorbed can be prevented when the object to be adsorbed is adsorbed.

[0016] 2. The power vacuum suction cup which can prevent displacement and self-rotation of the adsorbed object has a unloading mechanism. When the suction cup adsorbs the object to be adsorbed, the roller will contact the object to be adsorbed, and the roller will slide to both sides, so that the connecting rod will move upward, and when the fixed groove moves to above the fixed column, the rear end of the slider will be inserted into the fixed groove, so that the connecting rod will not move downward, and then the object to be adsorbed will be moved. When the object to be adsorbed is unloaded, the limit on the connecting rod is released, so that the connecting rod moves downward due to the elastic force of the second spring, thereby moving the roller downward, contacting the object to be adsorbed, and using the elastic force of the second spring to unload the object to be adsorbed, thereby preventing a certain connecting pipe from being damaged, which would lead to the phenomenon of difficulty in unloading.

[0017] 3. The powered vacuum suction cup which can prevent displacement and self-rotation of the adsorbed object has a fixing mechanism. When the connecting rod moves upward, the fixing groove will move upward. When the fixing groove moves to the top of the fixing column, the rear end of the slider will enter the fixing groove due to the elastic force of the third spring to limit the connecting rod. When unloading is required, the pull plate is pulled to make the rear end of the slider move out of the fixing groove, and the connecting rod unloads the adsorbed object through the elastic force of the second spring.

[0034] Embodiment 2

[0035] See also Figure 1-4 , and on the basis of the first embodiment, a discharging mechanism 4 is further obtained.

[0036] The unloading mechanism 4 includes a fixed sleeve 41, which is fixedly connected to the surface of the fixed column 1. A first hinged frame 42 is fixedly connected to the bottom of the fixed sleeve 41. A hinged column 43 is symmetrically hinged in the first hinged frame 42.

[0038] The top end of the second spring 411 is fixedly connected to the bottom of the fixing column 1 , and the bottom end of the second spring 411 is fixedly connected to the top of the sliding column 47 .

[0039] Embodiment 3

[0040] See also Figure 1-6, and on the basis of the first embodiment, a fixing mechanism 5 is further obtained.

[0041] The fixing mechanism 5 includes an L-plate 51, which is fixedly connected to the front face of the fixing column 1 in a left-right symmetrical manner. A slider 52 is connected to the front face of the L-plate 51 for forward and backward sliding movement. A pull plate 53 is fixedly connected to the front face of the slider 52. A limit plate 54 is fixedly connected to the surface of the slider 52 near the rear end. A third spring 55 is fixedly connected to the front face of the limit plate 54 in a left-right symmetrical manner. A fixing groove 56 is provided on the surface of the connecting rod 48.

[0042] The rear end of the slider 52 is an inclined surface, and the inclined surface faces downward. The front end of the third spring 55 is fixedly connected to the back of the L plate 51 .

[0043] In actual operation, when the device is used, the object to be adsorbed is placed under the four suction cups 37, and then the fixed column 1 is lowered to make the four suction cups 37 fit the surface of the object to be adsorbed. When the four suction cups 37 contact the object to be adsorbed, they will be affected by the elastic force of the first spring 36, which cushions the four suction cups 37 to prevent the four suction cups 37 from being damaged by collision after contacting the object to be adsorbed. Then, the vacuum pump 39 is started to extract the air in the suction cups 37 to adsorb the object to be adsorbed. After the adsorption is completed, the object to be adsorbed is raised. Since four suction cups 37 are provided, the object to be adsorbed can be prevented from displacement and rotation when adsorbing.

[0044] When the suction cup 37 adsorbs the object to be adsorbed, the roller 46 will contact the object to be adsorbed, and the roller 46 will slide to both sides, so that the connecting rod 48 moves upward. When the fixing groove 56 moves to the top of the fixing column 1, the rear end of the slider 52 will be inserted into the fixing groove 56, so that the connecting rod 48 will not move downward, and then the object to be adsorbed is moved. When the object to be adsorbed is unloaded, the limit of the connecting rod 48 is released, so that the connecting rod 48 moves downward due to the elastic force of the second spring 411, so that the roller 46 moves downward, and the roller 46 contacts the object to be adsorbed. The roller 46 uses the elastic force of the second spring 411 to unload the object to be adsorbed, so as to prevent a certain connecting pipe 38 from being damaged, which makes it difficult to unload.

[0045] When the connecting rod 48 moves upward, the fixed groove 56 will move upward. When the fixed groove 56 moves to the top of the fixed column 1, the rear end of the slider 52 will enter the fixed groove 56 due to the elastic force of the third spring 55, thereby limiting the connecting rod 48. When unloading is required, the pull plate 53 is pulled to make the rear end of the slider 52 move out of the fixed groove 56, and the connecting rod 48 unloads the object to be adsorbed through the elastic force of the second spring 411.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
