Description

Technical Field

[0001] The present application relates to the field of antenna measurement technology, and more specifically, to an antenna rapid testing fixture. Background Art

[0002] For manufacturers that mass-produce antennas, basic isolation and standing wave tests must be carried out after the antenna boards are processed. Only after passing the inspection can they be assembled and put into a darkroom or darkbox for overall testing.

[0003] Antenna factories typically use manual testing, which presents the following challenges: Each time a port's standing wave is measured, the RF cable must be tightened and loosened, and so on until the last port is reached. Each time the isolation between two ports is tested, both RF cables must be tightened and loosened. With a large number of ports, cross-wiring can easily lead to confusion about which ports have been tested and which have not. Manual tightening of RF ports can damage the antenna board. Frequent tightening and loosening of test ports can cause the cable to loosen, which most operators overlook, leading to product failures. For non-technical employees, learning the necessary basic antenna knowledge is challenging, inefficient, and difficult to resolve.

[0004] For mass production factories, each person needs to be equipped with a vector network analyzer, calibration parts, wrenches, etc., and a lot of time and labor training is required, which consumes a lot of money and time. However, for the antenna boards processed in the factory, which have multi-channel characteristics, manual testing is cumbersome and inefficient. Therefore, it is very necessary to develop a set of fast measurement systems for antenna boards. Utility Model Content

[0008] Furthermore, the opening directions of the test mounting bracket and the limiting fastener are perpendicular to each other.

[0014] Furthermore, a limit scale is fixedly connected to the support plate, and both sides of the bottom of the limit fastener are engaged and slidably connected with the limit scale.

[0015] The above technical solution makes it easy to accurately control the sliding distance of the limiting fastener.

[0016] Furthermore, a placement groove is provided on the top surface of the placement plate.

[0017] The above technical solution is used to stably place the antenna board.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the application discloses an antenna rapid test tool frame, which comprises a base 1 and a top plate 2, connecting rods 3 are fixedly connected at four corners between the base 1 and the top plate 2, a supporting plate 4 and a movable plate 5 are sequentially and slidably connected on the connecting rods 3 from bottom to top, a compression spring 6 is sleeved on the connecting rod 3 between the supporting plate 4 and the base 1, a pneumatic cylinder 7 is fixedly connected to the top plate 2 and penetrates downwards, the piston rod end of the pneumatic cylinder 7 is fixedly connected with the movable plate 5, a test mounting frame 8 is fixedly connected to the bottom of the movable plate 5, a probe test plate 9 is detachably installed in the test mounting frame 8, a plurality of test probes 10 are fixedly connected to the probe test plate 9 and penetrate the probe test plate 9, the probe test plate 9 with different arrangement modes can be replaced according to different models of test antenna plates, a limiting buckle 11 is movably connected to the top surface of the supporting plate 4, and a placing plate 12 is movably embedded in the inner side of the limiting buckle 11.

[0032] Please refer to Figure 1-2 The opening direction of the test mounting frame 8 and the limiting buckle 11 is perpendicular to each other, so that the relative position between the probe test plate 9 and the placing plate 12 can be adjusted in two directions.

[0033] Preferably, a clamping groove 13 is formed in the inner side of the test mounting frame 8, and a first fastening bolt 14 is threadedly connected to the outer side of the test mounting frame 8 and penetrates the test mounting frame 8, so that the placing plate 12 can be adjusted and fixed.

[0034] Preferably, a second fastening bolt 15 is connected to the limiting buckle 11 and penetrates the limiting buckle 11, a limiting displacement groove 16 is formed in the supporting plate 4, and the bottom end of the second fastening bolt 15 penetrates the limiting displacement groove 16 and is adjustably and slidably connected in the limiting displacement groove 16, so that the probe test plate 9 can be adjusted and fixed.

[0035] Preferably, a limiting scale 17 is fixedly connected to the supporting plate 4, and the bottom sides of the limiting buckle 11 are slidingly connected with the limiting scale 17, so that the sliding distance of the limiting buckle 11 can be accurately controlled.

[0036] Preferably, a placing groove 18 is formed in the top surface of the placing plate 12 and used for stably placing the antenna plate, and the placing plate 12 with different shapes of grooves can be replaced according to different models of antenna plates.

[0037] The implementation principle of the antenna rapid test tool frame is as follows: the probe test plate 9 is driven to move downwards under the action of the pneumatic cylinder 7 through the sliding of the connecting rods 3 and the movable plate 5, so that the test port of the antenna plate placed on the placing plate 12 is contacted and tested.

[0038] When in use, first replace the corresponding placement plate 12 and probe test plate 9 according to the model of the antenna board to be tested, and then adjust the relative position of the limit fastener 11 and the probe test plate 9 according to the contact point, so that when the probe test plate 9 falls, the test probe 10 can correspond to the corresponding test port of the antenna board, connect the test probe 10 with the matrix switch and the spectrum analyzer, put the antenna board to be tested into the placement groove 18 on the placement plate 12, turn on the air pressure pump switch, move the movable plate 5 to the top of the test antenna board, and insert the test probe 10 into the antenna test port. Turn on the automatic test software to complete the test; through the support plate 4 and the base 1 The setting of the compression spring 6 can prevent the damage of the test antenna board caused by inaccurate control of the stroke of the cylinder 7 when pressing down, and at the same time prevent the test probe 10 from relaxing its telescopic ability due to long-term testing, resulting in different forces between each probe when inserted into the port, resulting in test errors caused by loose interface docking, thereby improving test stability and accuracy; by setting the opening directions of the test mounting frame 8 and the limiting fastener 11 perpendicular to each other, it is convenient to adjust the relative position between the probe test board 9 and the placement board 12 in both directions.
