DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a radio frequency connector processing and assembly device provided by an embodiment of the present invention includes a base 1, both sides of the bottom of the base 1 are fixedly connected with legs 2, and also includes:

[0030] A guide assembly 3, wherein two guide assemblies 3 are symmetrically arranged on the base 1, and the guide assembly 3 includes a support block 301 fixedly connected to the base 1, and a transversely arranged conduit 302 is fixedly connected to the support block 301, and the conduits 302 on both sides are on the same axis, and a reserved spacing is arranged between the two conduits 302, and the reserved spacing needs to be greater than the overall length of the RF connector, and a silo 303 for storing the male or female head of the RF connector is fixedly connected to the top of the conduit 302, and the silo 303 itself is arranged in the vertical direction, and the silo 303 is connected to the inside of the conduit 302, and when the male or female head of the RF connector is located in the conduit 302, the inner wall of the conduit 302 contacts the outer surface of the male or female head;

[0031] A push assembly 4, wherein the push assembly 4 is arranged in one-to-one correspondence with the two guide assemblies 3, and the push assembly 4 includes a moving seat 401 slidably arranged on the base 1, and a push tube 402 is fixedly connected to the moving seat 401, and the push tube 402 is slidably inserted in the catheter 302 at one end away from the other catheter 302, and the moving seat 401 is used to drive the push tube 402 to move in the catheter 302, and a positioning block 403 is fixedly connected to one end of the push tube 402 facing the catheter 302, and a hole 404 matching the central conductor of the RF connector is opened on the positioning block 403;

[0032] The pressure adjustment component 5 is arranged on the movable seat 401 . When the push tube 402 pushes the male or female head of the RF connector in the catheter 302 , the pressure adjustment component 5 is used to adjust the air pressure state in the push tube 402 .

[0033] It should be noted that the shapes of RF connectors are varied. The present invention is mainly aimed at RF connectors with a regular cylindrical shape, so that both the silo 303 and the conduit 302 can have a good position restriction effect on them, thereby avoiding the occurrence of matching offset. The hole 404 on the positioning block 403 in the present invention is to match with the center conductor of the RF connector. Generally speaking, whether it is a male or female head of the RF connector, its center conductor needs to extend out of the shell it is wrapped in, so that it is convenient to connect with the wire. Therefore, the present invention uses the characteristic of the protruding center conductor to achieve precise positioning of the male or female head. At the same time, the cooperation between the hole 404 and the center conductor is also the basis for achieving adsorption and fixation. Of course, the RF connector targeted by the present invention is in the form of male and female plug-in.

[0034] In one embodiment of the present invention, the present invention is mainly aimed at the assembly process of RF connectors under special needs. Two silos 303 are respectively used to carry the male head and the female head of the RF connector. Automatic loading can be achieved by utilizing the gravity of the workpiece itself. The push tube 402 and the pressure adjustment assembly 5 cooperate to fix the male head or the female head on one end of the push tube 402. The push tubes 402 on both sides move toward each other to complete the docking assembly of the male head and the female head. With the reciprocating movement of the push tube 402 and the natural falling action in the silo 303, the uninterrupted docking assembly of the male head or the female head can be achieved. The device can continuously and quickly assemble the male head and the female head of the RF connector. In summary, the present invention can meet the special assembly requirements of the RF connector on the basis of a simple structure, and the actual effect is very obvious.

[0035] like Figure 1 and Figure 4 As shown, as a preferred embodiment of the present invention, guide rail grooves 6 are provided on both sides of the support block 301 on the machine base 1, and the movable base 401 includes an electrically controlled slide 4011 slidably arranged in the guide rail groove 6, and the tops of the electrically controlled slides 4011 on both sides are fixedly connected with support frames 4012, and the tops of the support frames 4012 are fixedly connected with ring bodies 4013, and the push tube 402 is fixedly arranged in the ring bodies 4013.

[0036] In one case of the present embodiment, the pressure adjustment component 5 includes a transverse plate 501 fixedly connected to the support frame 4012, the transverse plate 501 is located on the side of the support frame 4012 away from the support block 301, and an air pump 502 is fixedly connected to the transverse plate 501. An air pipe 503 is provided at the output end of the air pump 502, and the other end of the air pipe 503 is sealed and connected to the push tube 402 through a sealing cover 504. The sealing cover 504 and the positioning block 403 are respectively located at the two ends of the push tube 402, and the air pipe 503 is connected to the inside of the push tube 402. It should be emphasized that the air pump 502 is provided with a variable direction reversing valve, which is used to allow the air pump 502 to suck air from the push tube 402 to change the push tube 402. The push tube 402 is in a negative pressure state, or air is blown into the push tube 402 to change the push tube 402 into a positive pressure state. When the push tube 402 pushes the male or female head forward, the hole 404 on the positioning block 403 is closed by the center conductor, and the air pump 502 performs a suction action, so that the male or female head is adsorbed and fixed on one end of the push tube 402, thereby realizing the plugging of the male head and the female head through the opposite movement of the push tube 402. After the plug-in assembly is completed, the air pump 502 changes the direction of the airflow through the reversing valve, thereby delivering gas to the push tube 402. At this time, the center conductors at both ends of the RF connector will be squeezed out from the hole 404, thereby realizing the shedding processing of the RF connector after assembly.

[0037] like Figure 1 As shown, based on the previous embodiment, a rectangular opening 12 is provided on the base 1, and the rectangular opening 12 is located between the two support blocks 301. A vertically arranged feed channel 13 is fixedly connected in the rectangular opening 12. The cross-section of the feed channel 13 is rectangular and coincides with the contour shape of the RF connector after assembly. The top of the feed channel 13 and the top of the silo 303 are both wide-mouthed opening structures.

[0038] In one case of this embodiment, because a feed channel 13 is provided, after the RF connector falls off from the push tubes 402 on both sides, it will directly fall into the feed channel 13. The feed channel 13 serves to transport the assembled RF connector, facilitating the collection of the assembled parts.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, a conductor block 7 is fixedly connected inside the push tube 402, and the conductor block 7 is located on one side of the push tube 402 close to the positioning block 403. A circular hole 8 corresponding to the position of the hole 404 is opened on the conductor block 7, and a connector 9 with one end passing through the push tube 402 is fixedly connected to the ring body 4013. The connector 9 is connected to the conductor block 7 through a wire 10 located in the push tube 402, and a wiring harness 11 is detachably fixedly connected to the connector 9.

[0040] In one case of this embodiment, the other ends of the two wiring harnesses 11 are connected to a vector network analyzer. The present invention can not only be used for the assembly of RF connectors, but the electrical performance test of RF connectors is a very important link. Although the male and female heads of RF connectors are now standardized, there are still performance differences between individuals. The RF connectors assembled by the present invention have undergone quality inspection, but this quality inspection is generally a sampling quality inspection, and it is difficult to perform performance testing on each individual. However, due to the special assembly requirements of RF connectors, the present invention can achieve performance testing of each RF connector. When the device moves the male and female heads of the RF connector through two push tubes 402, the performance test can be completed using a vector network analyzer. The specific steps include:

[0041] S100, when the male and female connectors of the RF connector are plugged in, an insertion loss curve, a return loss curve, and a VSWR curve are obtained by a vector network analyzer;

[0042] S200, comparing the insertion loss curve, the return loss curve and the VSWR curve with corresponding standard parameters respectively;

[0043] S300, when the test is passed, a retraction work instruction is generated by the industrial computer and sent to the device, so as to retract the push tube 402 and change the inside of the push tube 402 to a positive pressure state;

[0044] S400, when the test fails, a stop command is generated by the industrial computer and sent to the device, so that the push tube 402 stops at the position where the RF connector is plugged in, and the air pump 502 stops working.

[0045] It should be further explained that the step of obtaining the insertion loss curve, the return loss curve and the VSWR curve by means of a vector network analyzer specifically includes:

[0046] S101, adjusting the vector network analyzer to S21 parameters through the industrial computer to obtain an insertion loss curve displayed on the vector network analyzer;

[0047] S102, adjusting the vector network analyzer to S11 parameters through the industrial computer, and respectively obtaining a return loss curve and a VSWR curve displayed on the vector network analyzer, wherein the S11 parameter is generally used to measure the reflection coefficient, and the return loss is also an indicator based on the reflection coefficient, so the two performance indicators of the RF connector can be measured through the S11 parameter;

[0048] S103, integrating and uploading the insertion loss curve, the return loss curve, and the VSWR curve.

[0049] It should be noted that S parameters are a way to describe the characteristics of multi-port networks, and are particularly suitable for measurements within the RF and microwave frequency ranges. For a two-port network, S parameters include S11, S21, S12, and S22, of which S11 and S21 are two more common parameters. When these two parameters are selected using a vector network analyzer, the vector network analyzer will output data about these two parameters, thereby being able to analyze the performance indicators related to the RF connector.

[0050] In one case of the present embodiment, by utilizing the fast transmission characteristic of electrical signals, when the male and female heads of the RF connector are plugged in, all performance tests can be completed with only a short stay. When the RF connector is fixed at one end of the push tube 402, the central conductors of the male and female heads will be inserted into the circular hole 8 of the conductor block 7. Once the male and female heads are plugged in, the male and female heads of the RF connector, the conductor block 7, the wire 10, the wiring harness 11 and the vector network analyzer form a closed circuit. The vector network analyzer is used to measure the insertion loss, return loss and voltage standing wave ratio of the RF connector. These three items are the main performances of the RF connector, and different test parameters need to be adjusted to be measured. When performing an insertion loss test, the S21 parameter will first be selected on the VNA of the vector network analyzer to measure the insertion loss, and the scanning function of the VNA will be started to perform an insertion loss test. After the test is completed, the VNA will display the insertion loss curve, and then the insertion loss curve will be analyzed by a computer. The analysis here is mainly related to The standard parameters are compared, as long as the insertion loss is within the allowable range. Of course, when performing the return loss test, it is necessary to select the S11 parameter on the VNA so that the return loss curve can be obtained. The subsequent analysis process is similar and will not be repeated. The VSWR curve is generated when testing the voltage standing wave ratio, and the specific process is relatively conventional, so it will not be described in this embodiment. The present invention can not only be used to assemble the male and female heads of the RF connector, but also can perform very accurate performance tests on each individual RF connector during the assembly process, thereby realizing the secondary quality inspection of the RF connector. When the test fails, it can be removed in time, so that the quality of the product received by the customer is more reliable. It is worth mentioning that the wiring harness 11 and the connector 9 are detachably connected, so the device can not only use the vector network analyzer to measure the three performances of the RF connector, but also can be matched with other test equipment, and can adjust the test items according to actual needs.

[0051] It should be noted that an insulating paint layer is provided on the inner wall of the push tube 402. Due to the presence of the conductor block 7, if there is no insulating paint layer, the push tube 402 will form a magnetic field after power is turned on, which will affect the transmission of internal electrical signals. After the insulating paint layer is provided, the performance test function of the device can be made more accurate.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
