Description

Technical Field

[0001] The present invention relates to the technical field of radio frequency coaxial cable detection, and in particular to a radio frequency coaxial cable detection device and a detection method of the detection device. Background Art

[0002] like Figure 1 The figure shows a type of RF coaxial cable assembly that is commonly used in current mobile communication systems. It consists of a right-angle push-in connector at one end, a RF coaxial cable connected in the middle, and a threaded connector installed in the direction of the flange at the other end. The main characteristics of this product that need to be tested after production are as follows: 1. The electrical indicators of the cable assembly itself, 2. The distance L from the mounting surface of the flange connector to the center line of the right-angle connector, 3. The direction of the right-angle connector must be aligned at 90° with the flange of the connector at the other end, 4. After the test is completed, a red mark point must be placed on the flange of the flange connector to fix the angle and position. This mark point is used to mark the direction of the flange installation when the RF coaxial cable is installed in the whole machine to ensure that the right-angle elbow is pushed in the correct direction and connected smoothly. The method currently commonly used for RF coaxial cable testing is to split the aforementioned four requirements into four separate processes for separate operations.

[0003] As can be seen from the above description, conventional measurement and testing methods employ a traditional, step-by-step assembly line model, requiring numerous processes and personnel, with most operations requiring manual operation and manual readings to determine pass / fail results. This traditional model, with its numerous process steps, wastes valuable human resources, and manual judgments are prone to errors, leading to missed defective products. Summary of the Invention

[0015] The present invention also provides a detection method for a radio frequency coaxial cable detection device, comprising:

[0016] Step 1: With the right-angle push-in connector facing vertically downward, place the flange of the RF coaxial cable to be tested on the flange bracket, and place the cable on the cable bracket to test whether the right-angle push-in connector of the RF coaxial cable to be tested can be connected to the curved connector tester. If the right-angle push-in connector cannot be connected to the curved connector tester, it is determined that the angle deviation between the two ends of the RF coaxial cable to be tested does not meet the requirements, and the test is terminated.

[0038] The straight connector tester bracket 32 is arranged at one end of the base 1; the straight connector tester assembly 31 is arranged on the straight connector tester bracket 32; the marking pen 33 is arranged on the straight connector tester bracket 32 on one side of the straight connector tester 31;

[0039] The slide rail 23 is arranged at the other end of the base 1, and a slider 231 is provided on the slide rail 23; the curved connector detector bracket 22 is mounted on the slider 231 of the slide rail 23, and can slide on the slide rail 23 toward the straight connector detector bracket 32; the fixed block 26 is arranged at one end of the slide rail 23; one end of the spring 25 is connected to the curved connector detector bracket 22, and the other end is connected to the fixed block 26; the curved connector detector 21 is arranged on the curved connector detector bracket 22; the screw slide 43 is arranged on the base 1 between the slide rail 23 and the straight connector detection group instrument bracket 32; the cable bracket 41 and the flange bracket 42 are both arranged on the slide of the screw slide 43, and the motor of the screw slide 43 drives the cable bracket 41 and the flange bracket 42 between the slide rail 23 and the straight connector detection group instrument bracket 32 Moves back and forth between the two ends; the image acquisition component bracket 52 is arranged on the base 1 on one side of the slide rail 23; there is a rectangular groove 421 on the flange bracket 42, and the rectangular groove 421 is slightly wider than the flange of the RF coaxial cable to be tested; a groove slightly wider than the cable line of the RF coaxial cable to be tested is opened on the cable bracket 41; the image acquisition component 51 is mounted on the image acquisition component bracket 52; the judgment window 54 is arranged between the image acquisition component bracket 52 and the slide rail 23, and the opening of the judgment window 54 is opposite to the image acquisition port of the image acquisition component 51; the pointer 53 is arranged on the curved connector tester bracket 22 and moves with the curved connector tester bracket 22; the detection controller is respectively connected to the curved connector tester 21, the straight connector detection group instrument 31, the screw slide 43, the limit switch 44, and the image acquisition component 51 circuit.

[0040] When testing and fixing the RF coaxial cable to be tested, first clamp the flange of the RF coaxial cable to be tested into the rectangular groove 421 of the flange bracket 42. The rectangular groove 421 can prevent the flange from rotating. When the cable of the RF coaxial cable to be tested is clamped into the groove of the cable bracket 41, the groove can keep the cable horizontal without sagging or bending. Finally, the right-angle push-in connector is docked with the curved connector tester 21. When the screw slide 43 drives the cable bracket 41 and the flange bracket 42 to move, the curved connector tester bracket 22 on the slide rail 23 will also move due to the dragging of the RF coaxial cable to be tested. Since the cable of the RF coaxial cable to be tested is flexible, the spring 25 between the curved connector tester bracket 22 and the fixed block 26 can stretch the cable of the RF coaxial cable to be tested, ensuring that the cable of the RF coaxial cable to be tested is always in a taut state, which is convenient for detecting the cable length of the RF coaxial cable to be tested.

[0041] The detection method of the detection device of the radio frequency coaxial cable of the present invention comprises:

[0042] Step 1: With the right-angle push-in connector facing vertically downward, the flange of the RF coaxial cable to be tested is mounted on the flange bracket 42, and the cable is placed on the cable bracket 41. The right-angle push-in connector of the RF coaxial cable to be tested is tested to see whether it can be docked with the curved connector tester 21. If the right-angle push-in connector cannot be docked with the curved connector tester 21, it is determined that the angle deviation between the two ends of the RF coaxial cable to be tested does not meet the requirements, and the test is terminated. If the right-angle push-in connector can be docked with the curved connector tester 21, the test process is continued.

[0043] Step 2: The detection controller drives the motor of the lead screw slide 43 to drive the slide on the lead screw to move toward the straight connector detection component 3 to detect whether the adapter of the RF coaxial cable to be tested can be docked with the straight connector tester 31. When the adapter cannot be docked with the straight connector tester 31, it is determined that the adapter deviates from the axis of the RF coaxial cable to be tested, and the detection is terminated. The motor of the lead screw slide 43 drives the slide on the lead screw to move away from the straight connector detection component 3 until it reaches the initial position; when the adapter can be docked with the straight connector tester 31, the detection process continues;

[0044] When the slide on the lead screw moves to the testing position and the adapter is docked with the straight connector tester 31, a dot is made on the flange of the RF coaxial cable to be tested using the dot pen 33;

[0045] Step 3: The electrical performance of the RF coaxial cable to be tested is tested by the detection controller in combination with the curved connector tester 21 and the straight connector tester assembly 31. If the electrical performance test does not meet the requirements, the motor of the lead screw slide 43 drives the slide on the lead screw to move away from the straight connector test assembly 3 until it reaches the initial position; if the electrical performance test meets the requirements, the test is continued;

[0046] Step 4: The image acquisition component 51 acquires an image of the position of the pointer 53 in the determination window 54, and the detection controller determines whether the length of the RF coaxial cable to be tested is within the tolerance range according to the position of the pointer 53 in the determination window;

[0047] Step 5: After the detection process is completed, the motor of the lead screw slide 43 drives the slide on the lead screw to move away from the straight connector detection assembly 3 until it reaches the initial position.

[0048] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention.
