[0027] Specifically, the anti-pinch finger structure of the labeling arm also includes a control device (not shown in the figure) for receiving the detection signal of the magnetic induction sensor 10 and controlling the stroke cylinder 2. The control device is an existing conventional equipment, which is well known to those skilled in the art and is widely used in this field. The document only protects the physical structure. Based on this, the control device is not elaborated in detail in this document. The magnetic induction sensor 10 is an existing conventional equipment. Its working principle is based on the magnetic induction phenomenon and Faraday's law of electromagnetic induction. It is a device that can convert magnetic signals into electrical signals. This is not elaborated in this document. At the same time, the utility model only protects the physical structure, and does not elaborate on the circuit system part of the control device, the stroke cylinder 2 and the magnetic induction sensor 10. The circuit system part is a basic circuit, which is well known to those skilled in the art and applied in this industry.
[0028] In this embodiment, a step hole 11 is formed through the top of the bracket 5, and the guide rod 4, the spring 7 and the magnetic ring 8 are all arranged in the inner cavity of the step hole 11, the bottom of the bracket 5 is connected to the top of the label suction plate 3, and an anti-collision area 12 is provided between the guide rod 4 and the label suction plate 3. The design of the anti-collision area 12 can prevent the guide rod 4 from colliding with the label suction plate 3 when the bracket 5 performs buffering movement, thereby ensuring the stability of the structure. Limiting ring pieces 13 are respectively installed at both ends of the guide rod 4, the limiting ring piece 13 at the bottom end is arranged at the bottom of the bracket 5, and the limiting ring piece 13 at the top end is arranged at the top of the plastic block 9, thereby ensuring the stability of the entire buffer mechanism and avoiding the problem of falling off.
[0029] Specifically, the magnetic ring 8 is sleeved on the guide rod 4 and placed between the limiting ring edge 6 and the plastic block 9 to ensure the installation stability of the magnetic ring 8 .
[0030] In this embodiment, a cylinder motion rod 14 is movably penetrated through the surface of the support 1, one end of the cylinder motion rod 14 is fixedly connected to the bracket 5, two cylinder motion rods 14 are provided, and a stabilizing block 17 is provided at one end of the two cylinder motion rods 14.
[0031] Specifically, the design of the stabilizing block 17 can ensure the stability of the two cylinder moving rods 14, thereby ensuring the stability of the movement of the bracket 5 driven by the stroke cylinder 2, and can enable the labeling arm to perform normal labeling actions within a certain range corresponding to objects of different heights, while also ensuring stability.
[0032] In this embodiment, a connecting plate 15 is installed on one side of the support 1, and a mounting hole is opened through the surface of the connecting plate 15. Specifically, the connecting plate 15 is used to facilitate the installation of the labeling arm at a corresponding position outside to meet normal use, thereby ensuring that the label suction plate 3 can ensure stability when attaching the label to the object to be attached, thereby improving the labeling accuracy.
[0033] In this embodiment, a mounting groove 16 is provided on the surface of the bracket 5, and the magnetic induction sensor 10 is disposed in the mounting groove 16. Specifically, the mounting groove 16 is used to install the magnetic induction sensor 10, so as to protect the magnetic induction sensor 10 and avoid damage caused by collision with the outside world.
[0034] The working principle and use process of the utility model are as follows: when in use, the label suction plate 3 can absorb the label to be attached, and then the stroke cylinder 2 is controlled by the existing control device in the outside world to work, so that the stroke cylinder 2 can push the label suction plate 3 to move downward via the bracket 5, which is conducive to attaching the label to the object to be attached, and the movement distance of the stroke cylinder 2 during labeling is set according to the system in the control device, so that the label suction plate 3 can move a certain distance and completely attach the label to the object to be attached, and when labeling according to the set movement distance, if there is an obstacle between the label suction plate 3 and the object to be attached, the label suction plate 3 can first touch the obstacle, and then the label suction plate 3 can push the bracket 5 to move upward after being subjected to force, and the bracket 5 can squeeze the spring 7 when moving, so that the bracket 5 can move between the magnetic ring 8 and the plastic The material block 9 moves upward without changing its position. During this period, a certain buffer can be provided by the force of the spring 7. In this way, when the label suction plate 3 touches an obstacle, the bracket 5 can move upward for a short distance, thereby reducing the problem of injury to the operator. Based on the above, after the bracket 5 moves, it can drive the externally installed magnetic induction sensor 10 to move synchronously, and then the position of the magnetic induction sensor 10 changes with the magnetic ring 8 as a reference. Therefore, the magnetic induction sensor 10 can detect the change in the position of the magnetic ring 8, and then the detection signal can be transmitted to the control device, prompting the control device to control the stroke cylinder 2 to automatically retract to its original position, so as to avoid the problem that the stroke cylinder 2 continues to descend and causes the operator to be pinched or the labeling mechanism to be damaged, thereby effectively preventing the occurrence of safety accidents.
