Description

The present application claims a priority from Chinese patent application No. 202310968731.4 entitled "LAMINATION PROCESS FOR RFID ELECTRONIC TAG FOR TIRE AND LAMINATION MECHANISM FOR RFID ELECTRONIC TAG FOR TIRE", which is filed with CNIPA on August 2, 2023, and the entire contents of which are incorporated into the present disclosure by reference. FIELD The present application relates to a technical field of tire device, and in particular to a lamination process for an RFID electronic tag used in a tire and a lamination mechanism for an RFID electronic tag used in a tire. BACKGROUND In traditional tire tread manufacturing processes, vulcanized tags serve as unique identifiers throughout the tire production process. Before Radio Frequency Identification (RFID) electronic tags are implanted into tires, some pre-processing is required: an RFID chip is encapsulated within a specially formulated rubber compound. Currently, when wrapping tire RFID electronic tags in rubber, the RFID electronic tags are typically placed between two layers of rubber sheets and pressed and bonded manually, and the lamination process is manually completed. This method is prone to secondary contamination of the RFID tags and rubber; it is inefficient, and the tag products cannot meet the needs of subsequent automated production. Furthermore, the inconsistent nature of worker operation leads to significant waste and defects, and the process requires a high level of operator skill. Some solutions employ mechanized processing to place the RFID electronic tag on a bottom layer of rubber strip (sheet), and use a pair of rollers to drag and press the bottom and top rubber strips together, thereby finally completing the lamination process. The above described process uses a pair of rollers to continuously drag two layers of rubber strips, but it is easy to cause tensile deformation of the rubber due to the inherent characteristics of rubber. Furthermore, in actual use, since the total winding path lengths of the upper and lower-layer rubber compounds are different, under the same tension, the strip passing through the longer winding path may produces greater tensile deformation during the dragging process by the pressure rollers than the strip passing through the shorter winding path. This results in uneven thickness of the two rubber sheets after lamination, generating internal stress and causing deformation in the final product or other stages of the production process. Moreover, during the continuous dragging of the rubber strips (sheets) by the pressing component, the tensile deformation of the rubber creates a difference in tensile deformation between the two layers. This causes the RFID tag placed on the bottom rubber strip (sheet) to shift when it comes into contact with the top rubber strip (sheet) during pressing, resulting in a difference in the posture of the RFID tag between the two rubber strips after lamination. Therefore, it can be seen that the existing lamination process for the RFID electronic tag has problems such as instability after lamination, susceptibility to deformation, differences in the posture of the RFID tags after lamination, and products do not meet requirements. SUMMARY The main purpose of this application is to provide a lamination process for an RFID electronic tag used in a tire and a lamination mechanism for an RFID electronic tag used in a tire to solve the problem of deformation of RFID electronic tags after lamination in existing lamination processes for the RFID electronic tag. To achieve the above purpose, according to an aspect of the present application, a lamination process for an RFID electronic tag used in a tire is provided, which includes: moving a lower-layer rubber compound and an upper-layer rubber compound by a driving component in a conveying direction; pressing the upper-layer rubber compound and the lower-layer rubber compound together by a pressing component to press an RFID electronic tag between the upper-layer rubber compound and the lower-layer rubber compound into the rubber compound, where during pressing the RFID electronic tag, the driving component stops moving the upper-layer rubber compound and the lower-layer rubber compound; after the pressing is completed by the pressing component, continuously moving the rubber compound pressed with the RFID electronic tag by the driving component. In an optional embodiment, the lamination process for the RFID electronic tag used in the tire further includes: the pressing component is movably arranged, and when the pressing component presses the upper-layer rubber compound and the lower-layer rubber compound, the pressing component moves in a direction parallel to the conveying direction, and presses the upper-layer rubber compound and the lower-layer rubber compound together within a predetermined distance. In an optional embodiment, the lamination process for the RFID electronic tag used in the tire further includes: when the pressin
