Abstract
Description
Technical Field
[0001] This utility model relates to the field of antenna manufacturing technology, and in particular to a testing fixture and system for antennas. Background Technology
[0002] An antenna is a device used to transmit or receive radio waves and is a key component of a wireless communication system. It converts electrical signals into electromagnetic waves (during transmission) or electromagnetic waves into electrical signals (during reception). After production, the antenna's performance needs to be tested. This usually requires manual connection of the testing equipment's testing end to the antenna's testing end. After testing, antennas that pass the test are laser-marked. Because antennas are mostly long and slender, specialized fixtures are needed for easy fixation. This production process of testing before marking has become the industry standard, resulting in low production efficiency and poor traceability. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a testing fixture and system for antennas that integrates testing and fixing onto the same fixture, thereby combining the testing and marking processes, improving production efficiency, and saving labor.
[0004] The technical solution to achieve the purpose of this utility model is:
[0005] A testing fixture for an antenna includes a fixed pad, on the upper surface of which a positioning fixture for placing the antenna under test is detachably fixed. A test block is slidably provided on the side of the positioning fixture along the length of the antenna. A test port corresponding to the antenna under test is fixedly provided on the side of the test block near the positioning fixture. A displacement mechanism mounted on the pad is connected to the side of the test block. The displacement mechanism is adapted to drive the test block to reciprocate so that the test port can be inserted into and separated from the antenna under test.
[0006] Furthermore, the displacement mechanism includes a base and a connecting seat respectively fixed on the pad block and the test block. The base has an integrally formed bushing at one end near the positioning fixture, and a movable wrench is hinged to the other end. A horizontally arranged connecting shaft is slidably inserted in the bushing. One end of the connecting shaft is fixedly connected to the connecting seat, and a connecting rod is hinged between the other end and the movable wrench.
[0007] Furthermore, the surface of the test block is provided with a through groove for placing the connecting wire of the test port. The test port is fixed to the end of the through groove by adhesive, and a pressure strip is provided on the top of the test block.
[0008] Furthermore, the surface of the positioning fixture is provided with a positioning groove adapted to the antenna under test, and the two sides of the positioning groove are connected by grooves.
[0009] Furthermore, a parallel linear guide rail is fixedly mounted on the pad, and the test block is fixedly connected to the slider of the linear guide rail.
[0010] Furthermore, the positioning fixture has symmetrical notches on both sides of one end near the test block, and a limit block is fixedly installed in the notch.
[0011] An antenna testing system includes a base, a computer pre-installed with testing software and marking software, a testing device, a marking device, and a testing fixture as described above. The pad of the testing fixture is fixed on the base. The test port is electrically connected to the testing device and the computer in sequence. The marking device is electrically connected to the computer and is located on the side of the positioning fixture with the marking port facing the antenna under test below. When the testing device detects that the antenna under test is qualified, the computer displays the testing data and sends a marking signal to the marking device to automatically mark the antenna under test.
[0012] Furthermore, the side of the testing fixture is provided with a testing button fixed on the base, and the testing button is electrically connected to the testing equipment.
[0013] By adopting the above technical solution, this utility model has the following beneficial effects:
[0014] (1) This utility model integrates the test block and the positioning fixture onto a single pad. The antenna under test is fixed by the station fixture, which facilitates subsequent laser marking operations. The displacement mechanism drives the test block to move, thereby driving the test port on it to be inserted into the antenna under test for detection. The entire detection fixture integrates the detection antenna and the fixed antenna onto the same fixture, thus integrating the detection and marking processes, improving production efficiency, and saving labor.
[0015] (2) The displacement mechanism of this utility model rotates the movable wrench in the forward or reverse direction, thereby driving the connecting shaft to reciprocate along the bushing via the connecting rod, which in turn drives the connecting seat to push the test block closer to and away from the positioning fixture. The structure is simple and the operation is convenient.
[0016] (3) By setting through grooves on the surface of the test block, the connection wires of the test port can be hidden in the through grooves, making the test site more tidy and reducing the risk of accidental contact.
[0017] (4) The positioning fixture of this utility model provides finger operation space for manual placement of the antenna under test by setting grooves on both sides of the positioning groove, making it convenient to pick up and improve the efficiency of placing and removing the antenna under test.
[0018] (5) This utility model achieves the sliding installation of the test block on the pad by using a linear guide rail. The structure is simple, the sliding is smooth, and the maintenance is convenient.
[0019] (6) This utility model limits the distance between the test block and the positioning fixture by setting a limiting block, thereby controlling the insertion depth of the test port and the antenna under test, and avoiding damage to the antenna under test due to excessive insertion of the test port or excessive force.
[0020] (7) This utility model integrates the testing equipment and marking equipment with the testing tooling to form a testing system with testing and automatic marking. It integrates performance testing and laser marking process, reducing the number of production personnel from the traditional 2 to 1, and reducing the total production cycle from 25s to 13.5s. The test results are linked with the laser marking. Laser marking is performed on qualified products and not on unqualified products, ensuring that qualified products are marked and unqualified products are not marked, thus reducing customer complaints. The computer realizes the correspondence between the test parameters and the laser marking content. The corresponding test parameters can be traced through the unique code generated by the laser marking on the product, which has strong traceability.
[0021] (8) This utility model facilitates manual testing by adding an external detection button. Attached Figure Description

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0028] (Example 1)
[0029] like Figures 1 to 2The antenna testing system shown includes a base, a computer 1 pre-installed with testing and marking software, a testing device 2, a marking device 3, and a testing fixture. The testing fixture includes a pad 4 fixed to the base. A positioning fixture 5 for placing the antenna under test is detachably fixed to the upper surface of the pad 4 by screws. A test block 6 is slidably mounted on the left side of the positioning fixture 5 along the length of the antenna. A test port 7 corresponding to the antenna under test is fixed on the right side of the test block 6. The test port 7 is electrically connected to the testing device 2 and the computer 1 in sequence. A displacement mechanism 8 mounted on the pad 4 is connected to the front of the test block 6. By manually operating the displacement mechanism 8, the test block 6 is moved back and forth, thereby allowing the test port 7 to mate and separate from the antenna under test, preparing for automatic testing. The marking device 3 is electrically connected to the computer 1 and is located on the side of the positioning fixture 5 with its marking port facing the antenna under test below. When the testing device detects that the antenna under test is qualified, the computer 1 displays the testing data and sends a marking signal to the marking device 3 for automatic marking of the antenna under test. By integrating testing equipment and marking equipment with testing fixtures, a testing system with both testing and automatic marking capabilities is formed. This system combines performance testing and laser marking processes, improving production efficiency and saving labor costs.
[0030] Specifically, the surface of the positioning fixture 5 is provided with a positioning groove 5-1 that is adapted to the antenna under test. The two sides of the positioning groove 5-1 are connected with grooves 5-2, which provide finger operation space for manual placement of the antenna under test, making it easy to pick up and improve the efficiency of placing and removing the antenna under test.
[0031] A parallel linear guide rail 9 is fixedly mounted on the pad 4. The test block 6 is fixedly connected to the slider of the linear guide rail 9, so as to slide on the pad 4. A through groove 6-1 for placing the connecting wire of the test port 7 is opened on the surface of the test block 6. The test port 7 is fixed to the right end of the through groove 6-1 by adhesive. A pressure strip 10 is fixed on the top of the test block 6.
[0032] The displacement mechanism 8 includes a base 8-1 and a connecting seat 8-2, which are respectively fixed on the pad 4 and the test block 6. One end of the base 8-1 near the positioning fixture 5 has an integrally formed bushing 8-3, and the other end is hinged to a movable wrench 8-4. A horizontally positioned connecting shaft 8-5 is slidably inserted into the bushing 8-3. One end of the connecting shaft 8-5 is fixed to the connecting seat 8-2, and the other end is hinged to the movable wrench 8-4 via a connecting rod 8-6. By rotating the movable wrench 8-4 in either the forward or reverse direction, the connecting rod 8-6 drives the connecting shaft 8-5 to reciprocate along the bushing 8-3, thereby causing the connecting seat 8-2 to push the test block 6 closer to and away from the positioning fixture, thus achieving the insertion and connection of the test port 7 with the antenna under test. The structure is simple and the operation is convenient.
[0033] Considering that the insertion depth and force cannot be directly felt when using a fixture to connect the test port 7 to the antenna under test, which may damage the antenna end, this embodiment has symmetrical notches on both sides of the positioning fixture 5 near the test block 6, and a limiting block 11 fixed to the pad block 4 is provided in the notch. The limiting block 11 limits the distance between the test block 6 and the positioning fixture 5, thereby ensuring an appropriate insertion depth.
[0034] In this embodiment, the testing device 2 is connected to the test port 7 using alligator clips and to the computer using an RS-232 serial cable. The marking device 3 is connected to the computer using a network cable. Considering the ease of use for operators, this embodiment has a testing button 12 fixed on the base on the side of the testing fixture, and the testing button 12 is electrically connected to the testing device 2.
[0035] In use, first place the antenna part to be tested into the positioning fixture 5, push the movable wrench 8-4 of the displacement mechanism 8, and connect the test port 7 to the test antenna to complete the test preparation. Press the test button 12 to perform the test, and the test data is directly transmitted to the computer 1. The specific test software and marking software are matched with the selected test equipment and marking equipment. The test parameters are automatically stored in the background. If the test is qualified, the computer sends an instruction to the marking equipment 3 for laser marking.
[0036] This invention integrates testing equipment and marking equipment with testing fixtures to form a testing system with both testing and automatic marking capabilities. It combines performance testing and laser marking processes, reducing the number of production personnel from two to one and the total production cycle time from 25 seconds to 13.5 seconds. The testing results are linked to the laser marking process; laser marking is performed on qualified products and not on unqualified products, ensuring that qualified products are marked and unqualified products are not, thus reducing customer complaints. The computer system tracks the correspondence between testing parameters and laser marking content, and the unique code generated by the laser marking on the product allows for the traceability of the corresponding testing parameters, resulting in strong traceability.
[0037] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
