[0026] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1 to 4 As shown, a label tearing mechanism provided in this embodiment is used to tear off a label with a non-glue section at the end. The label tearing mechanism includes a mobile robot 100 and an upper clamp 40, a lower clamp 50, a clamp cylinder 20 and a lifting cylinder 30 arranged on the arm 101 of the mobile robot 100. The mobile robot 100 refers to an automated robot device controlled by a control system in the prior art. The upper clamp 40 has a suction nozzle rod 41 that can be lifted and lowered. The suction nozzle rod 41 is a suction nozzle structure connected to a vacuum pumping device, and is provided with a vacuum access port 411 and a suction nozzle 412 located at the bottom of the upper clamp 40. The lifting cylinder 30 drives and connects the suction nozzle rod 41 to drive the suction nozzle rod 41 to move up and down; the lower clamp 50 is fixed on the clamp cylinder 20, and the clamp cylinder 20 drives the lower clamp 50 to move laterally, so that the lower clamp 50 switches between the clamping position corresponding to the suction nozzle rod 41 and the yielding position staggered from the suction nozzle rod 41.

[0029] This embodiment also provides a label tearing method based on the label tearing mechanism, comprising the following steps:

[0030] A1, provide the above-mentioned label tearing mechanism, the clamping jaw cylinder 20 drives the lower clamping jaw 50 to switch to the yielding position, and the movable robot 100 moves to make the upper clamping jaw 40 correspond to the non-glue section of the label; so that the nozzle rod 41 corresponds to the non-glue section of the label.

[0031] A2, the lifting cylinder 30 drives the nozzle rod 41 to move down and approach the non-glue section of the label, and the nozzle rod 41 sucks the non-glue section of the label. Specifically, the nozzle rod 41 moves down and sucks the non-glue section of the label. In this process, the nozzle rod 41 can directly contact the non-glue section of the label, or it can not contact the non-glue section of the label, and suck up the non-glue section of the label through suction.

[0032] A3, the lifting cylinder 30 lifts the nozzle rod 41 and the non-glue section of the label, so that the non-glue section rises.

[0033] A4, the clamping cylinder 20 drives the lower clamping jaw 50 to switch to the clamping position, that is, drives the lower clamping jaw 50 to be inserted laterally into the bottom of the non-glue section; the lifting cylinder 30 drives the suction nozzle rod 41 to move downward to clamp and fix the non-glue section of the label; that is, the non-glue section of the label is pressed onto the lower clamping jaw 50 by the suction nozzle rod 41 to achieve clamping and fixing.

[0034] A5, the mobile robot 100 moves the arm 101 to tear off the label.

[0035] In this way, the automated label tearing operation of the automated equipment is realized, and the operation is stable and efficient.

[0036] Furthermore, in this embodiment, the lower clamping jaw 50 has a contact platform 51 and a blowing port 52 laterally corresponding to the contact platform 51. When in the clamping position, the contact platform 51 directly corresponds to the suction nozzle rod 41. That is, in the corresponding label tearing method, in step A4, the suction nozzle rod 41 moves down to contact the contact platform 51, thereby clamping and fixing the non-glue section of the label.

[0037] At the same time, the air blowing port 52 arranged laterally can blow off the label by blowing air. That is, in the label tearing method, step A6 is also included, the lifting cylinder 30 drives the suction nozzle rod 41 to move upward, the suction nozzle rod 41 breaks the vacuum, and the label is released. At this time, the air blowing port 52 blows air to blow out the torn label.

[0038] Furthermore, in order to better ensure that the label is blown out, in this embodiment, the surface of the abutting platform 51 is recessed with a venting groove 511 connected to the blowing port 52. With such a configuration, when the blowing port 52 blows air, a portion of the air flow will be blown out from the venting groove 511, and this portion of the air flow directly acts on the bottom of the label, preventing the label from being attached to the abutting platform 51 and unable to be blown out in time. The blowing-off effect is better.

[0039] Specifically, a collection bucket 200 is provided under the arm 101 of the mobile robot 100 for collecting the blown-off labels.

[0040] Furthermore, in this embodiment, the outer end of the abutting platform 51 has an inclined guide surface 512. When the abutting platform 51 is inserted into the bottom of the non-glue section in step A4, it has a guiding effect, and the insertion is smoother.

[0041] Of course, in other embodiments, the structure of the lower clamping jaw 50 is not limited thereto.

[0042] Furthermore, in this embodiment, a fixing frame 10 is fixed on the arm 101 of the mobile robot 100, the clamping cylinder 20 is fixed on the fixing frame 10, the upper clamping jaw 40 is fixed on the cylinder body of the clamping jaw cylinder 20, and the lifting cylinder 30 is fixed on the upper clamping jaw 40. The assembly of each component is realized, and the connection structure is simple. Of course, in other embodiments, the assembly method of each component is not limited to this.

[0043] Furthermore, in this embodiment, the mobile robot 100 is also provided with an image collector 60 (such as a camera), which is used to collect label images and output them to the control system of the mobile robot 100; the image collector 60 is added to identify the position of the label, which is convenient for control operation. That is, in step A1, the label position is collected by the image collector 60, and the control system controls the arm 101 of the mobile robot 100 to move so that the upper clamp 40 corresponds to the non-glue section of the label. Automatic recognition and operation are achieved. Of course, in other embodiments, when the position of the label is fixed, the structure of the image collector 60 may not be required.

[0044] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
