Abstract
Description
Technical Field
[0001] The utility model relates to an RFID tag production device, in particular to a riveting point punch height fine-adjusting device. Background Art
[0002] With the continuous development of the Internet of Things (IoT), radio frequency identification (RFID) enables rapid wireless identification of objects and has been widely used in warehousing, logistics, retail, clothing, transportation, libraries, aviation, and other fields. RFID primarily uses a reader device to transmit electromagnetic waves. Upon receiving these waves, the detected object returns corresponding information for use. The RFID antenna is responsible for receiving and transmitting electromagnetic waves, and its performance has a direct impact on the recognition effect.
[0003] The manufacturing method of RFID antenna is as follows: first, two layers of aluminum foil are laminated on both sides of PET, then a pattern is printed on the aluminum foil, and then the aluminum foil is etched. Finally, the RFID antenna is obtained after testing and cutting.
[0004] Before final slitting, a riveting process takes place. Specifically, a punch is used to press the aluminum foil on one side. The pressure deforms the foil, penetrating the PET film and contacting the other foil, forming a riveted connection. This creates a conductive connection between the two foils. Each antenna is stamped using a single punch (each with 4, 6, or 9 pins). Since the material width is typically between 60 and 80 cm, and 10 to 30 antennas can be arranged simultaneously, the same number of punches is required.
[0005] In actual production, the punch is directly fixed to the lifting frame, which drives all the punches to move up and down to achieve stamping. It is very difficult to keep the upper and lower heights of all the punches consistent. It is easy to over-stamp or under-stamp, resulting in the aluminum foil on both sides being unable to conduct. Therefore, it is difficult to ensure that all antennas on the wide width can meet the quality requirements. Utility Model Content

DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0024] like Figure 1 As shown, the riveting point punch height fine-adjustment device includes a main body, a telescopic part, a spring, a slider, a screw, and a punch.
[0025] The telescopic member can be positioned vertically in the main body, the punch 10 is fixed to the bottom end of the telescopic member, the slider 7 can be positioned horizontally in the main body, the screw 8 is used to drive the slider to move horizontally, and the spring 9 is provided between the main body and the telescopic member to reset the telescopic member. Figure 1 、 Figure 2 As shown, when the slider moves horizontally to the left, the slider presses the telescopic member downward to make the punch descend, and when the slider moves horizontally to the right, the spring drives the telescopic member to move upward to make the punch rise.
[0026] The main body includes a support 1, a bottom plate 2, a slider baffle 3 and a screw baffle 4. The bottom plate is fixed to the bottom of the support by screws, and the slider baffle and the screw baffle are respectively fixed to both sides of the support by screws.
[0027] The support is provided with a support hole 1-1, which is a stepped hole. The bottom plate is provided with a bottom plate hole 2-1. The support hole and the stepped hole are arranged on the same vertical axis.
[0028] The telescopic member is positioned vertically and telescopically within the main body. It comprises a coaxially connected adjusting screw 5 and a sliding rod 6. The adjusting screw is positioned vertically and slidably within a support hole. A spring is disposed within the support hole and fits over the adjusting screw. The ends of the spring respectively support the head of the adjusting screw and the stepped surface of the support hole. The sliding rod is positioned vertically and slidably within the bottom plate hole. The punch is fixed to the bottom end of the sliding rod.
[0029] The slider is positioned horizontally within the support, which is equipped with a horizontally extending slideway 1-2 to guide the slider's movement. The slideway is flanked by slide grooves 1-3, and the slider is equipped with slide rails 7-1 on either side to engage with the slide grooves. The slider also has an adjustment hole 7-2 extending through the top and bottom surfaces, through which an adjustment screw passes and then connects to the slide rod.
[0030] An upper inclined surface 6-1 is provided on the top of the slide rod, and a lower inclined surface 7-3 matching the upper inclined surface is provided on the bottom surface of the slider. The spring applies an upward thrust to the telescopic part so that the lower inclined surface is close to the upper inclined surface. When the slider moves to the left, the lower inclined surface squeezes the upper inclined surface to cause the punch to drop. When the slider moves to the right, the punch rises under the action of the spring.
[0031] The screw can be positioned on the screw baffle so as to rotate around a horizontal axis. The left end of the screw engages with the screw hole of the slider. The right end of the screw is provided with a handwheel 11, which has an indicator scale for displaying the rotation angle. When the handwheel is turned, the slider can be driven to move horizontally through the screw, thereby fine-tuning the upper and lower heights of the punch.
[0032] The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.
