It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the description of the present invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present invention and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the scope of the present invention.

As shown in fig. 1 and 2, in some embodiments of the present invention, the removal device includes an adsorption device 10, a first driving device 20, and a cutting device 30, the adsorption device 10 being configured to adsorb an outer package 2 of an article 1, the first driving device 20 being configured to drive the adsorption device 10 to move relative to the article 1 in an adsorbed state to increase a distance between the outer package 2 and the article 1, and the cutting device 30 being configured to cut the outer package 2.

In the above embodiment, the outer package removing device comprises the adsorption device 10, the first driving device 20 and the cutting device 30, the outer package 2 of the article 1 can be sucked by the adsorption device 10, then the adsorption device 10 sucks the outer package 2 and the article 1 to pull away a certain distance under the action of the first driving device 20, and finally the outer package 2 is cut by the cutting device 30, so that the outer package is automatically removed, the labor intensity is effectively reduced, the manpower waste is avoided, the production efficiency is improved, and the product quality is guaranteed.

In the above embodiment, by providing the first driving device 20, before the outer package 2 is cut by the cutting device 30, the adsorbing device 10 can be moved relative to the article 1 in the adsorbed state by the first driving device 20, so that the outer package 2 is pulled away from the article 1 by a certain distance, and the article 1 is prevented from being scratched when the cutting device 30 cuts the outer package 2, thereby protecting the article 1.

In some embodiments, the overwrap removal device further comprises a second drive device 40, the second drive device 40 being configured to drive the suction device 10 and the cutting device 30 in a synchronized motion relative to the article 1.

By providing the second driving means 40, the adsorbing means 10 and the cutting means 30 can be driven to move relative to the article 1, so that the adsorbing means 10 and the cutting means 30 are driven to be close to the article 1 when adsorption and cutting are required, and the adsorbing means 10 and the cutting means 30 are driven to be far away from the article 1 after cutting is completed, so as to avoid interference with components in subsequent processes.

Moreover, by arranging the second driving device 40, the synchronous movement of the adsorption device 10 and the cutting device 30 relative to the article 1 can be realized, so that the adsorption device 10 and the cutting device 30 can synchronously approach or depart from the article 1, the continuous operation of adsorption and cutting actions is convenient to control, the operation time is saved, and the dismantling efficiency is improved.

For example, before the dismantling device starts to work, the relative positions of the adsorption device 10 and the cutting device 30 can be adjusted, so that after the second driving device 40 drives the adsorption device 10 and the cutting device 30 to reach the preset positions, the adsorption device 10 attracts the outer package 2, and the adsorption device 10 and the outer package 2 are pulled away from the article 1 by a certain distance under the driving action of the first driving device 20, the distance between the cutting device 30 and the outer package 2 just enables the cutting device 30 to cut the outer package 2 without scratching the article 1, and thus the cutting device 30 can directly start the cutting operation without spending time to adjust the distance between the cutting device 30 and the outer package 2. That is, by driving the synchronous movement of the suction device 10 and the cutting device 30 with respect to the article 1 by the second driving device 40, it is possible to save time for adjusting the distance between the cutting device 30 and the article 1 before starting cutting after suction, thereby effectively improving the removal efficiency.

In some embodiments, the outer package removal device further comprises a mounting base 70, the mounting base 70 being connected to the drive portion of the first drive device 20, and the suction device 10 and the cutting device 30 are mounted on the mounting base 70.

By providing the mounting base 70 and mounting both the suction device 10 and the cutting device 30 on the mounting base 70, the purpose of synchronously driving the suction device 10 and the cutting device 30 to move relative to the article 1 can be achieved when the first driving device 20 drives the mounting base 70 to move relative to the article 1. That is, the first driving means 20 may drive the suction means 10 and the cutting means 30 to move synchronously with respect to the article 1.

In some embodiments, the second drive device 40 is disposed on the mount 70. This has the advantage that the first drive means 20, the suction means 10 and the cutting means 30 arranged on the mount 70 can move together with the mount 70 relative to the article 1 when the first drive means 20 drive the mount 70 relative to the article 1. On the mounting 70, the second driving device 40 can drive the suction device 10 and the cutting device 30 to synchronously move relative to the article 1. It can be seen that, although the first driving device 20 and the second driving device 40 can both drive the adsorbing device 10 and the cutting device 30 to move synchronously relative to the article 1, the first driving device 20 and the second driving device 40 are two different driving components, and when the first driving device 20 drives the adsorbing device 10 and the cutting device 30 to move synchronously, the second driving device 40 also moves synchronously together; while the second driving device 40 drives the adsorption device 10 and the cutting device 30 to synchronously move, the second driving device is not directly connected with the action of the first driving device 20.

In some embodiments, the suction device 10 further comprises a first mounting plate 12, the first mounting plate 12 is connected to the driving portion of the second driving device 40, and the suction device 10 and the cutting device 30 are mounted on the first mounting plate 12.

In some embodiments, the suction device 10 further comprises a negative pressure detection device for detecting the amount of pressure within the suction cup 11. When the negative pressure detection device detects that the pressure of the sucker 11 reaches a preset value, a signal is given that the sucker 11 has adsorbed the outer package 2. After receiving the signal from the negative pressure detecting device, the first driving device 20 starts to drive the adsorbing device 10 and the cutting device 30 to move backwards integrally, so that a certain distance is generated between the outer package 2 and the article 1 for subsequent cutting.

In some embodiments, the cutting device 30 comprises a third drive device 32 and a cutter 31, the third drive device 32 being configured to drive the cutter 31 in movement relative to the overpack 2.

In some embodiments, after the overpack 2 is severed, the overpack 2 may be removed manually or the overpack 2 may be removed by a robotic arm.

In some embodiments, cutter 31 includes a cutter body and a blade, the extension of the blade relative to the cutter body being adjustable. This arrangement allows for the initial distance between the blade and the article 1 to be adjusted as required to facilitate subsequent adjustment of the distance of movement of the cutter 31. The extension length of the blade is adjustable, and the blade can adapt to different working conditions or different sizes of the articles 1.
