Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic tags, and more specifically, to a tag peeling device and an electronic tag implantation device. Background Technology
[0002] In existing technologies, the production process of embedding RFID (Radio Frequency Identification) electronic tags into tires has seen the emergence of automated technologies for peeling, gripping, and conveying the electronic tags to the mounting process. The basic principle of current automated embedding equipment is to peel, grip, convey, and then mount the tag from the material roll. A peeling unit separates the electronic tag from the base film, a conveying unit transports the electronic tag to a preset position, and a tag gripping and mounting unit grips and mounts the electronic tag. However, this technology requires high tag viscosity, and currently suffers from problems such as material extrusion and peeling failure during tag removal. Summary of the Invention
[0003] The main objective of this invention is to provide a tag peeling device and an electronic tag implantation device to solve the problem of easy peeling failure during tag peeling in the prior art.
[0004] To achieve the above objectives, according to one aspect of the present invention, a label peeling device is provided, comprising a first peeling plate, a second peeling plate, and a transition mechanism. The first peeling plate and the second peeling plate are arranged sequentially along the label conveying direction, and a peeling gap is formed between a first end of the first peeling plate and a second end of the second peeling plate. The release film at the bottom of the label is turned from the first side of the peeling gap to the second side of the peeling gap at the first end of the first peeling plate, and after passing through the transition mechanism, it is turned from the second side of the peeling gap to the first side of the peeling gap at the second end of the second peeling plate.
[0005] Furthermore, the first end and / or the second end have a pointed corner structure, the upper surface of the pointed corner structure is parallel to the conveying direction of the first stripping plate, and the lower surface of the pointed corner structure forms an angle with the upper surface of the pointed corner structure.
[0006] Furthermore, along the top-to-bottom direction, the lower surface of the sharp-angled structure extends away from the peeling gap.
[0007] Furthermore, the transition mechanism has a first contact point that first contacts the separator and a last contact point that last contacts the separator. The direction of movement of the separator at the first contact point is parallel to or forms an acute angle with the lower surface of the sharp corner structure of the first peeling plate, and the direction of movement of the separator at the last contact point is parallel to or forms an acute angle with the lower surface of the sharp corner structure of the second peeling plate.
[0008] Furthermore, the upper surfaces of the first and second peeling plates serve as conveying surfaces, the separating film is located on the conveying surfaces and conveyed along the conveying surfaces, and the conveying surfaces of the first and second peeling plates are flush.
[0009] Furthermore, the transition mechanism includes a support wheel located on the second side of the peeling gap, with the release membrane wrapped around the support wheel.
[0010] Furthermore, there are multiple support wheels, and the support wheels are distributed on both sides of the longitudinal surface passing through the peeling gap.
[0011] Furthermore, along the conveying direction of the first peeling plate, the distance between the two sides of the peeling gap is greater than the sum of the thicknesses of the two separating films.
[0012] Furthermore, the label peeling device also includes a traction mechanism, which works in conjunction with the release film drive to transport the release film on the first peeling plate, the transition mechanism, and the second peeling plate.
[0013] According to another aspect of the present invention, an electronic tag implantation device is provided, including the tag peeling device described above.
[0014] By applying the technical solution of this invention, a first peeling plate and a second peeling plate are provided, with a peeling gap between them. On the one hand, labels with low viscosity can be directly peeled off from the first end of the first peeling plate. On the other hand, for labels with high viscosity that fail to be peeled off from the first peeling plate, the label is acted upon by the release film conveyed from bottom to top at the second end at the peeling gap. Specifically, at the first end, the label has a downward tendency to move because it fails to separate from the release film. At the second end, the release film at the second end conveys the label upward, giving it an upward tendency to move. Since the upward and downward tendencies are equal in magnitude and opposite in direction, the label separates from the release film at the first end under the action of the release film at the second end, thus achieving label peeling. This avoids label peeling failure and material squeezing problems, and improves the stability of the label peeling device. Attached Figure Description

[0023] To address the problem of label peeling failure that often occurs during existing technologies, this invention provides a label peeling device and an electronic tag implantation device, wherein the electronic tag implantation device includes the label peeling device described below.
[0024] like Figure 1 , Figure 2 The label peeling device shown includes a first peeling plate 10, a second peeling plate 20, and a transition mechanism 30. The first peeling plate 10 and the second peeling plate 20 are arranged sequentially along the label 52 conveying direction, and there is a peeling gap 40 between the first end of the first peeling plate 10 and the second end of the second peeling plate 20. The release film 51 at the bottom of the label 52 turns from the first side of the peeling gap 40 to the second side of the peeling gap 40 at the first end of the first peeling plate 10, and after passing through the transition mechanism 30, turns from the second side of the peeling gap 40 to the first side of the peeling gap 40 at the second end of the second peeling plate 20.
[0025] This embodiment, by setting a first peeling plate 10 and a second peeling plate 20, and setting a peeling gap 40 between the first peeling plate 10 and the second peeling plate 20, allows for the direct peeling of labels 52 with low viscosity from the first end of the first peeling plate 10. For labels 52 with high viscosity that fail to be peeled off from the first peeling plate 10, the release film 51, conveyed from bottom to top at the second end, acts at the peeling gap 40. Specifically, at the first end, the label 52 has a downward tendency to move because it fails to separate from the release film 51. At the second end, the release film 51 conveys the label upward, giving it an upward tendency to move. Since the upward and downward tendencies are equal in magnitude and opposite in direction, the label 52 separates from the release film 51 at the first end under the action of the release film 51 at the second end, thus peeling off the label 52. This avoids label peeling failure and material squeezing problems, improving the stability of the label peeling device.
[0026] It should be noted that the label to be peeled consists of two parts: a release film 51 and a label 52. The label 52 is evenly arranged on the release film 51 and adheres to it. The label 52 can be made of rubber. In this embodiment, the label to be peeled is conveyed to the first peeling plate 10, and the label 52 is peeled off at the peeling gap 40, which is the first end of the first peeling plate 10. The release film 51 continues to be conveyed on the transition mechanism 30 and the second peeling plate 20. For ease of explanation, the first side mentioned in this embodiment refers to the area above the peeling gap 40, and the second side refers to the area below the peeling gap 40. Of course, depending on the actual use, the actual positions of the first side and the second side can be interchanged.
[0027] like Figure 1As shown, in this embodiment, the first end and / or the second end have a pointed corner structure 11. The upper surface of the pointed corner structure 11 is parallel to the conveying direction of the first peeling plate 10, and the lower surface of the pointed corner structure 11 forms an angle with the upper surface of the pointed corner structure 11. Specifically, in this embodiment, both the first end and the second end have a pointed corner structure 11. The upper surface of the pointed corner structure 11 is also the upper surface of the first peeling plate 10. The label to be peeled is conveyed from the upper surface of the first peeling plate 10, passes through the pointed corner structure 11, and changes its direction of movement at the lower surface of the pointed corner structure 11. For labels 52 with low viscosity, when the label to be peeled passes through the pointed structure 11 at the first end, the pointed structure 11 itself has a certain angle, so the release film 51 is transported from the upper surface to the lower surface of the pointed structure 11. During this process, the movement direction of the release film 51 changes drastically, thus forming a certain gap between the label 52 and the release film 51, thereby achieving the peeling of the label 52. The label 52 can then be picked up by the picking robot. For labels 52 with high viscosity, when the label to be peeled passes through the first end, the high viscosity causes the label 52 to continue to stick to the release film 51. The label 52 continues to move under the drive of the release film 51. At this time, the first end and the second end work together, that is, the release film 51 passing through the first end from top to bottom drives the label 52 towards the peeling gap 40, attempting to drive the label 52 at the first end. The label 52 moves downward at the sharp corner structure 11. At this time, the label 52 has a downward movement tendency. At the same time, as the release film 51 conveyed at the second end passes through the sharp corner structure 11 at the second end from bottom to top, the release film 51 at the second end comes into contact with the label 52 that has not been peeled off by the first end. The release film 51 at the second end gives the label 52 an upward movement tendency. This upward movement tendency is equal in magnitude and opposite in direction to the aforementioned downward movement tendency, thereby separating the label 52 from the release film 51 and achieving the peeling off of the label 52. Subsequently, as the release film 51 is conveyed, the label 52 as a whole separates from the release film 51 at the first end and is conveyed from the first end to the second end. Then, the picking robot takes away the label 52. During the above process, due to the action of the release films 51 at both the first end and the second end, the label 52 can be separated from the release film 51 without causing the label 52 to be squeezed and deformed. Of course, a pointed structure 11 can also be provided only at the first end to ensure that the isolation film 51 passing through the second end can contact the end of the label 52, thereby peeling off the label 52 against the conveying direction of the label 52.
[0028] In this embodiment, in order to ensure that the sharp corner structure 11 can better perform the peeling function, the lower surface of the sharp corner structure 11 extends away from the peeling gap 40 in the direction from top to bottom. That is to say, the solid part of the sharp corner structure 11 is actually an acute angle structure. In this way, when the label to be peeled passes through the first end, the instantaneous change in the velocity direction of the isolation film 51 is large, which can more effectively peel off the label 52.
[0029] like Figure 2 As shown, in this embodiment, the transition mechanism 30 has a first contact point that first contacts the separator 51 and a last contact point that last contacts the separator 51. The movement direction of the separator 51 at the first contact point is parallel to the lower surface of the sharp corner structure 11 of the first peeling plate 10, and the movement direction of the separator 51 at the last contact point is parallel to the lower surface of the sharp corner structure 11 of the second peeling plate 20. This ensures that the conveying direction of the separator 51 between the first end and the transition mechanism 30 is along the extending direction of the lower surface of the sharp corner structure 11 at the first end, and the conveying direction of the separator 51 between the second end and the transition mechanism 30 is along the extending direction of the lower surface of the sharp corner structure 11 at the second end. This guarantees the degree of change in the velocity direction of the separator 51, thereby ensuring that the sharp corner structure 11 effectively performs its peeling function, while also ensuring the smooth and rapid conveying of the separator 51, avoiding multiple changes in the conveying direction that would increase the conveying resistance and affect the conveying efficiency. Of course, in addition to the parallel arrangement mentioned above, a roughly parallel arrangement can also be adopted, that is, the direction of movement of the separator 51 at the first contact point forms an angle with the lower surface of the sharp corner structure 11 of the first peeling plate 10, and the direction of movement of the separator 51 at the last contact point also forms an angle with the lower surface of the sharp corner structure 11 of the second peeling plate 20. The two angles mentioned above can be acute angles, or more preferably, values less than 30 degrees.
[0030] Optionally, since the conveying directions of the two parts are different, the transition mechanism 30 can play the role of adjusting the conveying direction. That is, the isolation membrane 51 changes its movement direction at the transition mechanism 30 to match the lower surface direction of the sharp corner structure 11 at the first end and the second end.
[0031] In this embodiment, the upper surfaces of the first peeling plate 10 and the second peeling plate 20 serve as conveying surfaces. The release film 51 is located on the conveying surfaces and conveyed along them, with the conveying surfaces of the first peeling plate 10 and the second peeling plate 20 being flush. That is, a single strip of release film 51 is conveyed on both the first peeling plate 10 and the second peeling plate 20, ensuring that the movement speed of the release film 51 at both ends is equal. This guarantees that the upward and downward movement speeds of the label 52 are equal, ensuring a counteracting effect and thus guaranteeing the peeling effect. Simultaneously, the flush arrangement of the upper surfaces of the first peeling plate 10 and the second peeling plate 20 forms a horizontally extending peeling gap 40 between the first and second ends. This allows the first and second ends to cooperate at the peeling gap 40 to complete the peeling of the label 52. Furthermore, the peeled label 52 remains horizontally positioned for easy removal by a robotic arm.
[0032] In this embodiment, the transition mechanism 30 includes a support wheel 31 located below the peeling gap 40, with the separator 51 passing around it. Thus, the support wheel 31 supports the separator 51 and guides its movement. Firstly, after passing around the support wheel 31, the separator 51 changes from a downward to an upward motion, resulting in different transport directions for the separator 51 at the first and second ends. This ensures that the separator 51 at the second end can effectively perform its peeling function. Secondly, the support wheel 31 is positioned below, matching the extension direction of the lower surface of the sharp-angle structure 11, thus simultaneously ensuring the effectiveness of the sharp-angle structure 11 and the smooth transport of the separator 51.
[0033] In this embodiment, there are multiple support wheels 31, and the support wheels 31 are distributed along both sides of the longitudinal surface of the peeling gap 40, preferably in a symmetrical distribution. In this embodiment, there are two support wheels 31, which are respectively located at the same distance below the first peeling plate 10 and the second peeling plate 20. In order to match the symmetrical arrangement of the two sharp corner structures 11 with respect to both sides of the longitudinal surface of the peeling gap 40, this embodiment uses two support wheels 31 that are also symmetrically arranged with respect to both sides of the longitudinal surface of the peeling gap 40. In this way, after the release film 51 passes the first end sharp corner structure 11, it continues to be conveyed downward along the extension direction of the lower surface of the sharp corner structure 11, and is conveyed to the support wheel 31 below the first peeling plate 10. After the support wheel 31 changes direction, it continues to be conveyed horizontally to the support wheel 31 below the second peeling plate 20. The support wheel 31 changes the conveying direction of the release film 51 to the extension direction of the lower surface of the second end sharp corner structure 11, and continues to convey it to the second end sharp corner structure 11, and then leaves from the upper surface of the second peeling plate 20. Of course, the support wheels 31 can also be set in other quantities and positions, as long as they can satisfy the requirement that the separating film 51 passes through the label 52 in reverse at the peeling gap 40 to perform the peeling function.
[0034] In this embodiment, along the conveying direction of the first peeling plate 10, the distance between the two sides of the peeling gap 40 is greater than the sum of the thicknesses of the two layers of release film 51, and less than the sum of the thicknesses of the two layers of release film 51 and the label 52. In this way, it can ensure that the release film 51 passes smoothly through the peeling gap 40, and also ensure that the label 52 with high viscosity will not move with the release film 51 to the lower surface of the sharp corner structure 11 at the sharp corner structure 11 of the first peeling plate 10.
[0035] In this embodiment, the label peeling device further includes a traction mechanism, which works in conjunction with the release liner 51 to drive and transport the release liner 51 on the first peeling plate 10, the transition mechanism 30, and the second peeling plate 20. The release liner 51 is pulled by the traction mechanism, which in turn drives the label 52 to move at a uniform speed along the transport direction, thereby ensuring that the release liner 51 or the label 52 transported to the first peeling plate 10, the transition mechanism 30, and the second peeling plate 20 move at the same speed. The release liner 51 can be driven by electric or pneumatic components, as long as they can pull the release liner 51 to move at a uniform speed.
[0036] It should be noted that "multiple" in the above embodiments refers to at least two.
[0037] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:
[0038] 1. Solve the problem of label peeling failure that easily occurs in existing technologies;
[0039] 2. It avoids label peeling failure and material squeezing problems, thereby improving the stability of the label peeling device;
