Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Combine the following Figure 1-Figure 4 The utility model is described as an RFID module test fixture, which includes: a base 100, a bracket 200, a moving mechanism 300 and an operating mechanism 400.

[0038] A table top is arranged on the base 100; wherein the table top comprises a first table top 101 and a second table top 102, wherein the first table top 101 is fixed on the base 100, the second table top 102 is located above the first table top 101, a connecting column 103 is arranged between the second table top 102 and the first table top 101, a first end of the connecting column 103 is fixedly embedded in the second table top 102, a second end of the connecting column 103 is movably passed through the first table top 101 and then extends into a groove 104 on the top wall of the base 100, a limiting portion is arranged at the second end of the connecting column 103 to limit the second end of the connecting column 103 from being separated from the groove 104; a compression spring 105 is sleeved on the connecting column 103, a first end of the compression spring 105 is connected to the second table top 102, a second end of the compression spring 105 is connected to the first table top 101, a sinking groove 106 corresponding to the compression spring 105 is arranged on the upper end surface of the first table top 101, and the second end of the compression spring 105 is located in the sinking groove 106. That is, under the action of the compression spring 105, there is a certain distance between the second table 102 and the first table 101 in a natural state. When the second table 102 is subjected to a downward force, the compression spring 105 will play a certain buffering role to prevent the second table 102 from being subjected to a rigid force. In order to ensure the movement stability between the second table 102 and the first table 101, three connecting columns 103 can be provided to ensure movement stability.

[0039] The upper end surface of the second table top 102 is provided with a placement groove 107 for placing the RFID module 500; wherein, the shape of the placement groove 107 is adapted to the contour of the RFID module 500 so that the RFID module 500 can be placed in the placement groove 107, and the placement groove 107 corresponds to the clamping column 303.

[0040] A plurality of first ejector pins 600 are arranged on the first table 101, and a first through slot corresponding to the first ejector pins 600 is opened on the second table 102. The first ejector pins 600 are movably inserted into the first through slots, and the first through slots are communicated with the placement slot 107. In terms of specific position, the first ejector pins 600 are located on the side of the placement slot 107 close to the bracket 200. In a natural state, the first ejector pins 600 do not extend into the placement slot 107. When the RFID module 500 is placed into the placement slot 107 and the second table 102 is pressed down, the first ejector pins 600 extend into the placement slot 107 and dock with the first station of the RFID module 500. The first ejector pins 600 are also electrically connected to external testing instruments such as a computer terminal, etc., to perform corresponding tests on the RFID module 500.

[0041] The bracket 200 is disposed on one side of the base 100 , and a guide column 201 is also disposed between the bracket 200 and the base 100 ;

[0042] The moving mechanism 300 is arranged above the table, and the moving mechanism 300 is slidably connected to the guide column 201, so that the moving mechanism 300 can slide along the guide column 201, and a pressing column 303 is arranged on the lower end surface of the moving mechanism 300. Specifically, four pressing columns 303 are arranged, corresponding to the four vertices of the placement groove 107;

[0043] The operating mechanism 400 is movably connected to the bracket 200 and also movably connected to the moving mechanism 300, and is used to control the moving mechanism 300 to slide along the guide column 201, so that the moving mechanism 300 is close to or away from the table.

[0044] The moving mechanism 300 includes a moving plate 301 and a column 302. A through hole is provided on one side of the moving plate 301. The guide column 201 movably passes through the through hole. In order to ensure the smooth movement between the moving plate 301 and the guide column 201, two guide columns 201 are provided. The moving plate 301 may be further provided with a sleeve at the through hole. The guide column 201 movably passes through the sleeve.

[0045] The upper end surface of the movable plate 301 is connected to one end of the column 302, and the other end of the column 302 is hinged to the operating mechanism 400 through a connecting piece 304. The lower end surface of the movable plate 301 is provided with a pressing column 303;

[0046] The bracket 200 is provided with a guide cylinder 202, and the column 302 is movably provided with the guide cylinder 202; the two guide columns 201 and the guide cylinder 202 are respectively located at the three vertices of the triangle, and correspondingly, the two sleeves and the column 302 are also located at the three vertices of the triangle, and the cooperation further ensures the stability of the moving plate 301 during movement. The guide column 201 is sleeved with a buffer spring 203, one end of the buffer spring 203 is connected to the lower end of the moving plate 301 (when a sleeve is provided, it is connected to the lower end of the sleeve), and the other end of the buffer spring 203 is connected to the base 100.

[0047] The operating mechanism 400 includes a handle 401, a first end of which is hinged to the connecting member 304, and the first end of the handle 401 is also protruded toward one side to form a connecting portion 402, and the connecting portion 402 is hinged to the bracket 200. That is, the handle 401 is in a "7"-shaped structure, the vertex of the bend is hinged to the connecting member 304, and the protruding connecting portion 402 is hinged to the bracket 200, so that when the handle 401 is rotated, the handle 401 can drive the column 302 to move up and down, and then drive the moving plate 301 to move up and down; specifically, when the second end of the handle 401 is rotated downward toward the front side of the base 100, it will drive the column 302 and the moving plate 301 to move downward, and vice versa, it will drive the column 302 and the moving plate 301 to move upward. In this embodiment, the connecting member 304 can be an arched plate-like structure, and the recessed portion of the arched structure faces the side of the hinge point between the handle 401 and the bracket 200, so as to avoid movement interference between the connecting member 304 and the above-mentioned hinge point (i.e., the hinge point between the handle 401 and the bracket 200), so that the second end of the handle 401 can be flipped to the rear side of the base 100 (i.e., above the bracket 200).

[0048] The movable plate 301 is provided with a plurality of second ejector pins 700 facing downward, and the upper ends of the second ejector pins 700 penetrate the movable plate 301 and are connected to the first connecting wire 701, which is used to connect an external test instrument and is a rigid connecting wire; specifically, the second ejector pins 700 are located on the side of the movable plate 301 away from the bracket 200. When the movable plate 301 moves downward, the second ejector pins 700 are driven to move downward, and then the second ejector pins 700 are docked with the second station of the RFID module 500 to perform corresponding tests on the RFID module 500.

[0049] In this embodiment, when the moving plate 301 moves downward, the pressing column 303 presses down the RFID module 500, and then squeezes the second table 102 to move downward, so that the first ejector pin 600 extends into the placement groove 107 and docks with the first station of the RFID module 500 smoothly, and at the same time, the second ejector pin 700 docks with the second station of the RFID module 500 smoothly. Of course, the above-mentioned stations are pin welding positions or contacts at specific positions with electrical connection functions, so as to dock with the ejector pins to form electrical connections.

[0050] A mounting frame 800 is provided on one side of the mobile plate 301, and a four-arm helical antenna 801 is installed on the mounting frame 800. A second connecting line 802 is provided on the four-arm helical antenna 801. The second connecting line 802 is used to connect to the antenna interface of the RFID module 500 to perform a corresponding functional test on the RFID module 500. The second connecting line 802 is a flexible connecting line. Further, a avoiding through slot 108 corresponding to the mounting frame 800 is opened on the top wall of the base 100.
