Technical Field

[0001] The invention relates to the technical field of RFID tag testing equipment, in particular to a single-chip RFID tag bending resistance testing machine. Background Art

[0002] RFID tag, also known as RFID electronic tag or electronic tag, is the popular name of radio frequency identification. When RFID tags leave the factory, in order to set the technical parameters and standards of RFID tags, it is usually necessary to test their bending resistance. That is, it includes length direction bending test, width direction bending test and twisting test. The length direction bending test requires fixing the two ends of the electronic tag in the length direction, and then moving them relatively to make the middle part of the electronic tag arch so as to achieve the purpose of bending test; the width direction bending test requires fixing the two ends of the electronic tag in the width direction, and then moving them relatively to make the middle part of the electronic tag arch so as to achieve the purpose of bending test; the twisting test requires fixing the two ends of the electronic tag in the length direction, and then twisting one end or twisting the two ends in opposite directions to make the middle of the electronic tag twist so as to achieve the purpose of twisting test.

[0003] In the prior art, different testing devices are required for the above-mentioned bending and twisting tests of RFID electronic tags, and the electronic tags need to be repeatedly removed and re-clamped, which makes the testing efficiency low. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art to at least a certain extent: to provide a single-chip RFID tag bending resistance testing machine, which can complete the bending test in the length direction, the bending test in the width direction and the twisting test after the electronic tag is clamped once, thereby making the testing process more efficient and comprehensive.

[0005] To this end, an object of the present invention is to provide a single-chip RFID tag bending resistance testing machine, comprising Base; Two vertical plates are symmetrically arranged along the length direction of the base and are arranged on the base in a manner that the distance between the two vertical plates is adjustable; A clamping head is arranged on the vertical plate and is used for clamping the sheet-shaped product; Any vertical plate is provided with two clamps, the two clamps are spaced apart in the width direction, and at least one of the two clamps is slidably matched with the corresponding vertical plate, so that the distance between the two clamps is adjustable; A length direction driver and a width direction driver, wherein the length direction driver is installed on the base and is used to drive the two vertical plates to move relative to or away from each other; wherein the width direction driver is installed on the vertical plate and is used to drive the two chucks on the vertical plate to move relative to or away from each other.

[0006] The four corners of the product are fixed and clamped by four clamps on two vertical plates. At this time, the relative and opposite movement of the two vertical plates can complete the bending test in the length direction of the product. Secondly, the relative and opposite movement between the two clamps on the same vertical plate can complete the bending test in the width direction of the product. Finally, the product can complete the bending test in the length direction and the bending test in the width direction in sequence after one clamping. The overall test takes a short time, and the test process saves multiple clamping operations, making the test process more convenient.

[0007] According to an example of the present invention, the two vertical plates include a fixed vertical plate and a movable vertical plate, the fixed vertical plate is fixedly connected to the base, and the movable vertical plate is slidably matched with the base. One of the two vertical plates is fixed and the other is movable, so the long direction driver only needs to drive the movable vertical plate to reciprocate and translate to complete the adjustment of the distance between the two vertical plates, thereby making the connection structure between the long direction driver and the vertical plate simpler and more reliable.

[0008] According to an example of the present invention, the base has a first slide groove extending in the length direction, the fixed vertical plate is fixed to one end of the first slide groove, and the movable vertical plate is slidably fitted in the first slide groove. Through the first slide groove, the lower end of the movable vertical plate is located in the first slide groove, and under the guiding effect of the first slide groove, the translation process of the movable vertical plate is more stable.

The carrier plate on the vertical plate can rotate around the rotating shaft so as to complete the torsion test of the product. Finally, the product can complete the bending test in the length direction, the bending test in the width direction, and the torsion test in sequence after one clamping.

[0012] According to an example of the present invention, there are two carriers, which are symmetrically arranged on the two vertical plates, and the axes of the rotating shafts on the two carriers are colinear. The two carriers can be twisted in opposite directions, so that the torsion test process is more convenient.

[0030] Embodiment 2 Based on one of the specific ways in which the distance between the two vertical plates can be adjusted in the above-mentioned embodiment 1: The two vertical plates include a fixed vertical plate 2 and a movable vertical plate 3 . The fixed vertical plate 2 is fixedly connected to the base 1 , and the movable vertical plate 3 is slidably matched with the base 1 .

[0031] The base 1 has a first slide groove 10 extending along the length direction. The fixed vertical plate 2 is fixed to one end of the first slide groove 10 , and the movable vertical plate 3 is slidably fitted in the first slide groove 10 .

[0032] Preferably, a guide rod is provided in the first slide groove 10, and both ends of the guide rod are fixed to the inner wall of the first slide groove 10.

[0039] Preferably, the fixed block 6.1 is a C-shaped structure, and the fixed block 6.1 includes an upper plate, a lower plate and an intermediate vertical plate. The two ends of the intermediate vertical plate are fixedly connected to the same side of the upper plate and the lower plate respectively. The movable pressure plate 6.2 is located between the upper plate and the lower plate, and the knob 6.3 is located on the upper plate. The threaded convex shaft part on the knob 6.3 passes through the threaded hole on the upper plate and is connected to the movable pressure plate 6.2. The knob 6.3 is threadedly matched with the threaded hole on the upper plate, thereby driving the movable pressure plate 6.2 downward or upward by rotating the knob 6.3, so that the part of the product 13 located in the clamping space is clamped or loosened.

[0040] Preferably, the vertical plate is provided with a second slide groove 4.3 extending in the width direction of the vertical plate, and the two clamps 6 are provided with sliders slidably matched with the second slide groove 4.3 at positions corresponding to the second slide groove 4.3. Through the sliding match between the slider and the second slide groove 4.3, the two clamps 6 on the same vertical plate can only move relative to or away from each other.

A double-headed screw 12 is provided between the two chucks 6, and the two ends of the double-headed screw 12 are respectively threadedly connected to the threaded holes 3.1 on the two chucks 6, and the threads at the two ends of the double-headed screw 12 have opposite rotation directions, and the output shaft of the motor is transmission-connected to the middle position of the double-headed screw 12.

[0042] Embodiment 5 In the above embodiment, after the four chucks 6 clamp the four corners of the product 13, the bending test in the length direction and the bending test in the width direction of the product can be realized by the relative movement of the two vertical plates and the relative movement between the two chucks on each vertical plate.

[0048] Specifically, Figure 5 As shown, the width direction driver 9 includes a motor fixed to the carrier plate 4, the output shaft of the motor extends to a position between the two chucks 6 close to the back plate 4.1, a double-headed screw 12 is provided between the two chucks 6, both ends of the double-headed screw 12 are respectively threadedly connected to the threaded holes 3.1 on the two chucks 6, and the threads at both ends of the double-headed screw 12 have opposite rotation directions, and the output shaft of the motor is transmission-connected to the middle position of the double-headed screw 12.
