Description

Technical Field

[0001] This invention relates to the field of microwave testing, and more specifically to a microwave module testing platform and method. Background Technology

[0002] In the microwave module manufacturing process, inter-process visual inspection and electrical performance testing are key steps in detecting the quality of microwave module products. Visual inspection mainly checks the assembly quality during the module production process, while electrical performance testing mainly uses professional instruments to test the electrical performance indicators of the microwave module. However, due to the complex wiring and high integration of microwave modules, following the traditional process flow of visual inspection first and then electrical performance testing makes it difficult to record and evaluate the correlation between the assembly quality of key processes and the electrical performance of the product in real time. This leads to the gradual accumulation of debugging difficulties in the later stages, ultimately resulting in low production efficiency and great difficulty in tracing problems. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the present invention provides a microwave module testing platform and method.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a microwave module testing platform, including an operation platform and a testing platform, wherein an A plug cylinder, a B plug cylinder, an RF clamping cylinder, a conversion plug clamping cylinder and a video plug conversion cylinder are installed on the operation platform;

[0005] An RF connection mechanism is fixed on one edge of the operating platform. The test platform is slidably connected to the upper surface of the operating platform. The RF clamping cylinder is connected to the test platform for loading microwave modules. The test platform can insert the microwave module into or remove it from the RF connection mechanism under the drive of the RF clamping cylinder.

[0006] The operating platform is slidably equipped with an A plug, a B plug, and an RF plug. The A plug, B plug, and RF plug are respectively connected to a converter plug via wires. The RF plug is assembled between the A plug and the B plug. The A plug cylinder is used to drive the A plug and the RF plug to move simultaneously and insert into the microwave module on the test platform. The B plug cylinder is used to drive the B plug and the RF plug to move simultaneously and insert into the microwave module on the test platform.

[0007] The adapter clamping cylinder is slidably mounted on the operating platform. The adapter clamping cylinder is connected to the adapter and drives the adapter to extend from the operating platform to connect with the video plug. The video plug conversion cylinder is connected to the adapter clamping cylinder and drives the adapter clamping cylinder and the adapter on it to correspond to different video plugs.

[0008] The beneficial effects of the present invention are as follows: The microwave module testing platform of the present invention, by integrating various cylinders, radio frequency plugs, adapter plugs, radio frequency connection mechanisms, etc. on the operating platform, can simultaneously realize fully automatic power-on control and automatic electrical performance testing of microwave modules, replacing manual operation, ensuring continuity and reliability, and significantly improving testing accuracy and efficiency.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the test platform has a positioning block on its peripheral edge, and the operating platform is also equipped with a side-push cylinder. The driving end of the side-push cylinder is connected to a push block, which is located above the test platform. The driving direction of the side-push cylinder is perpendicular to the driving direction of the radio frequency clamping cylinder.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting a positioning block, when the microwave module is positioned and clamped by the side-push cylinder, it can play a positioning role.

[0012] Furthermore, the A-plug cylinder, B-plug cylinder, RF clamping cylinder, side-push cylinder, adapter plug clamping cylinder, and video plug adapter cylinder are all equipped with a first position sensor and a second position sensor to detect the cylinder extension and retraction position.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting a position sensor, the cylinder positioning control function can be achieved.

[0014] Furthermore, the driving directions of the A-plug cylinder, the B-plug cylinder, and the RF clamping cylinder are all the same; the driving direction of the adapter plug clamping cylinder is opposite to that of the RF clamping cylinder; and the driving direction of the adapter plug clamping cylinder is perpendicular to that of the video plug adapter cylinder.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by limiting the driving direction of each cylinder, they do not interfere with each other during the driving process.

[0016] Furthermore, an A board, a B board, and an RF plug assembly board are slidably connected on the operating platform. The A plug is mounted on the A board, the B plug is mounted on the B board, and the RF plug is mounted on the RF plug assembly board. The A plug cylinder is connected to the A board, and the B plug cylinder is connected to the B board. The RF plug assembly board is mounted on two slide rails of the operating platform. The A board is slidably connected to one slide rail, and the B board is slidably connected to the other slide rail. The A board and the B board are respectively located on the side of the RF plug assembly board away from the test platform.

[0017] Furthermore, the A board and the B board extend to both sides above the RF plug assembly board, and the A board and the B board are respectively provided with elastic buckles that engage with the RF plug assembly board on the side near the test platform; the operating platform is provided with rollers that roll against the upper surface of the A board and the B board, and the rollers are used to press the corresponding elastic buckles and release the RF plug assembly board from the A board or the B board on the side near the test platform.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by setting elastic buckles, a stable connection and fit can be achieved when the A board or B board moves synchronously with the RF plug assembly board.

[0019] Furthermore, it also includes a modular gripping arm and a PLC controller. The modular gripping arm is installed on one side of the operating platform. The modular gripping arm is equipped with a vision module for image extraction from the microwave module. The modular gripping arm, vision module, A-plug cylinder, B-plug cylinder, RF clamping cylinder, adapter plug clamping cylinder, and video plug conversion cylinder are all communicatively connected to the PLC controller.

[0020] The advantages of adopting the above-mentioned further solution are: It enables fully automated loading and unloading of microwave modules, automatic power-on control, and simultaneous automatic appearance inspection and electrical performance testing, achieving unattended operation for both processes. Furthermore, because the two processes are performed simultaneously, the correlation between assembly quality and product electrical performance can be recorded and evaluated in real time, allowing for timely adjustments. This significantly reduces the difficulty of later debugging, minimizes rework and repairs, and enhances the overall information-based quality traceability.

[0021] A microwave module testing method, implemented using the aforementioned microwave module testing platform, includes:

[0022] The module gripping arm uses a module gripping arm to grab the microwave module and place it at the barcode scanner position for QR code scanning. The barcode scanner sends the acquired QR code information to the PLC controller, and the module gripping arm places the microwave module onto the test platform.

[0023] The PLC controller parses the QR code information, determines the specific model of the microwave module, and controls the A plug cylinder, B plug cylinder, RF clamping cylinder, adapter plug clamping cylinder, and video plug conversion cylinder to operate according to the specific model of the microwave module. The PLC controller is also used to control the vision module to take pictures of the microwave module on the test platform and to perform surface defect identification and analysis by extracting the surface image of the microwave module.

[0024] The beneficial effects of this invention are as follows: The microwave module testing method of this invention realizes fully automated loading and unloading, automatic power-on control, and simultaneous automatic appearance inspection and electrical performance testing of the microwave module testing process, achieving unattended operation for both processes. By replacing manual operation with machine vision inspection and automatic testing, continuity and reliability are guaranteed, and inspection accuracy and efficiency are significantly improved.

[0025] Furthermore, the PLC controller parses the QR code information, determines the specific model of the microwave module, and controls the actions of the A-plug cylinder, B-plug cylinder, RF clamping cylinder, adapter plug clamping cylinder, and video plug conversion cylinder according to the specific model of the microwave module; specifically including:

[0026] When the QR code information is A1, the video plug conversion cylinder extends, aligning the connected conversion plug clamping cylinder and the conversion plug with the first video plug. After the video plug conversion cylinder extends to its position, the A plug cylinder extends and the B plug cylinder retracts. After the A plug cylinder and the B plug cylinder are in position, the RF clamping cylinder and the conversion plug clamping cylinder extend simultaneously, connecting the microwave module to the RF connection mechanism, the A plug, and the RF plug respectively. After successful connection, the microwave module is powered on for testing.

[0027] When the QR code information is A2, the video plug conversion cylinder retracts, aligning the connected conversion plug clamping cylinder and the conversion plug with the second video plug. After the video plug conversion cylinder retracts, the A plug cylinder extends and the B plug cylinder retracts. After the A plug cylinder and the B plug cylinder are in position, the RF clamping cylinder and the conversion plug clamping cylinder extend simultaneously, connecting the microwave module to the RF connection mechanism, the A plug, and the RF plug respectively. After successful connection, the microwave module is powered on for testing.

[0028] When the QR code information is B1, the video plug conversion cylinder extends, aligning the connected conversion plug clamping cylinder and the conversion plug with the first video plug. After the video plug conversion cylinder extends to its position, the A plug cylinder retracts, and the B plug cylinder extends. After the A plug cylinder and the B plug cylinder are in position, the RF clamping cylinder and the conversion plug clamping cylinder extend simultaneously, connecting the microwave module to the RF connection mechanism, the A plug, and the RF plug respectively. After successful connection, the microwave module is powered on for testing.

[0029] When the QR code information is B2, the video plug conversion cylinder retracts, aligning the connected conversion plug clamping cylinder and the conversion plug with the second video plug. After the video plug conversion cylinder extends to its position, the A plug cylinder retracts, and the B plug cylinder extends. After the A plug cylinder and the B plug cylinder are in position, the RF clamping cylinder and the conversion plug clamping cylinder extend simultaneously, connecting the microwave module to the RF connection mechanism, the A plug, and the RF plug respectively. After successful connection, the microwave module is powered on for testing.

[0030] The beneficial effect of adopting the above-mentioned further solution is that it enables the testing of four different types of microwave modules.

[0031] Furthermore, before the robot grasps the microwave module to the barcode scanner position for QR code scanning, the process also includes a vision module on the module grasping arm visually photographing and locating the microwave module grasping position, and sending the microwave module position obtained by the visual photographing and locating to the PLC controller. The PLC controller controls the suction cup device on the module grasping arm to complete the grasping of the microwave module by means of a vacuum suction cup according to the microwave module position.

[0040] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0041] like Figures 1-4 As shown, a microwave module testing platform according to this embodiment includes an operating platform 100 and a testing platform 200. The operating platform 100 is equipped with an A-plug cylinder 101, a B-plug cylinder 102, an RF clamping cylinder 103, a converter plug clamping cylinder 104, and a video plug conversion cylinder 105. An RF connection mechanism 112 is fixed to one edge of the operating platform 100. The testing platform 200 is slidably connected to the upper surface of the operating platform 100. The RF clamping cylinder 103 is connected to the testing platform 200 for loading microwave modules. The testing platform 200 can, under the drive of the RF clamping cylinder 103, allow the microwave module to be inserted into or removed from the RF connection mechanism 112. An A-plug 107, a B-plug 108, and an RF plug 109 are slidably mounted on the operating platform 100. The A-plug 107 and B-plug 108... The RF plug 109 is connected to the adapter plug 106 via wires. The RF plug 109 is mounted between the A plug 107 and the B plug 108. The A plug cylinder 101 is used to drive the A plug 107 and the RF plug 109 to move simultaneously and insert into the microwave module on the test platform 200. The B plug cylinder 102 is used to drive the B plug 108 and the RF plug 109 to move simultaneously and insert into the microwave module on the test platform 200. The adapter plug clamping cylinder 104 is slidably disposed on the operating platform 100. The adapter plug clamping cylinder 104 is connected to the adapter plug 106 and drives the adapter plug 106 to extend from the operating platform 100 and connect to the video plug. The video plug conversion cylinder 105 is connected to the adapter plug clamping cylinder 104 and drives the adapter plug clamping cylinder 104 and the adapter plug 106 on it to correspond to different video plugs.

[0042] Specifically, such as Figure 1 As shown, the adapter clamping cylinder 104 can be slidably connected to the operating platform 100 via the linear guide rail 114. It should be noted that both the linear guide rail 114 and the slide rail 113 mentioned later can adopt the same structural type or different structural types, as long as they can meet the linear movement of the components on them.

[0043] like Figure 1 As shown, the test platform 200 in this embodiment has a positioning block 201 on its peripheral edge, and the operating platform 100 is also equipped with a side-push cylinder 121. The driving end of the side-push cylinder 121 is connected to a push block, which is located above the test platform 200. The driving direction of the side-push cylinder 121 is perpendicular to the driving direction of the RF clamping cylinder 103. By setting the positioning block, the side-push cylinder can be used to position and clamp the microwave module, thus achieving a positioning function.

[0044] Specifically, such as Figure 1 As shown, one side of the test platform 200 is also provided with a notch 202 for the push block to be inserted into the drive end of the side push cylinder 121.

[0045] Specifically, such as Figure 1 As shown, the A-plug cylinder 101, B-plug cylinder 102, RF clamping cylinder 103, side-push cylinder 121, adapter plug clamping cylinder 104, and video plug adapter cylinder 105 are all equipped with a first position sensor and a second position sensor to detect the cylinder's extension and retraction position. By setting position sensors, the cylinder's positioning control function can be achieved.

[0046] like Figure 1 As shown, in this embodiment, the driving directions of the A-plug cylinder 101, the B-plug cylinder 102, and the RF clamping cylinder 103 are all the same; the driving direction of the adapter plug clamping cylinder 104 is opposite to that of the RF clamping cylinder 103; and the driving direction of the adapter plug clamping cylinder 104 is perpendicular to that of the video plug adapter cylinder 105. By limiting the driving directions of each cylinder, they do not interfere with each other during the driving process.

[0047] like Figure 2 As shown, in this embodiment, the operating platform 100 is slidably connected to an A-plate 115, a B-plate 116, and an RF plug assembly plate 117. The A-plug 107 is mounted on the A-plate 115, the B-plug 108 is mounted on the B-plate 116, and the RF plug 109 is mounted on the RF plug assembly plate 117. The A-plug cylinder 101 is connected to the A-plate 115, and the B-plug cylinder 102 is connected to the B-plate 116. The RF plug assembly plate 117 is mounted on two slide rails 113 of the operating platform 100. The A-plate 115 is slidably connected to one slide rail 113, and the B-plate 116 is slidably connected to the other slide rail 113. The A-plate 115 and the B-plate 116 are respectively located on the side of the RF plug assembly plate 117 away from the test platform 200.

[0048] like Figure 2 and Figure 3As shown, in this embodiment, plate A 115 and plate B 116 extend to both sides above the RF connector assembly plate 117. Plate A 115 and plate B 116 are respectively provided with elastic latches 118 on the side near the test platform 200, which engage with the RF connector assembly plate 117. The operating platform 100 is provided with rollers 119 that roll against the upper surfaces of plate A 115 and plate B 116. The rollers 119 are used to press against the corresponding elastic latches 118 and release the RF connector assembly plate 117 from the side near the test platform 200 by disengaging it from plate A 115 or plate B 116. By setting the elastic latches, a stable connection and engagement can be achieved when plate A or plate B moves synchronously with the RF connector assembly plate. Specifically, as shown... Figure 2 As shown, the operating platform 100 is provided with connecting columns 120 on one side of the A plate 115 and the B plate 116 respectively, and the connecting columns 120 are provided with rollers 119.

[0049] Furthermore, such as Figure 3 As shown, the elastic buckle 118 is hinged to plate A 115 or plate B 116. Both plate A 115 and plate B 116 have through holes for the elastic buckle 118 to extend out. One end of the elastic buckle 118 extends out of the through hole from the upper surface of plate A 115 or plate B 116 and is adapted to the roller 119. The other end of the elastic buckle 118 is connected to a groove on the lower surface of plate A 115 or plate B 116 by a spring. Moreover, the elastic buckle 118 is located at the end of plate A 115 or plate B 116 near plug A 107 and plug B 108. When the A-plug cylinder 101 pushes the A-plug 107 forward, it simultaneously pushes the RF plug assembly plate 117 and the RF plug 109 on it. At this time, the roller 119 corresponding to the A-plate 115 no longer presses against the elastic buckle 118 on the A-plate 115, causing one end of the elastic buckle 118 connected to the spring to pop out from the groove at the bottom of the A-plate 115 and engage with the front end of the RF plug assembly plate 117, so that the RF plug assembly plate 117 and the A-plate 115 move synchronously. When the A-plug cylinder 101 pulls the A-plate 115 and the A-plug 107 back, the roller on the A-plate 115 rolls along the upper surface of the A-plate 115 until it contacts one end of the protruding through hole of the elastic buckle 118 and presses the elastic buckle 118 into the through hole. At the same time, by using leverage, one end of the elastic buckle 118 connected to the spring is hidden in the groove below the A-plate 115, releasing the engagement and positioning between the A-plate 115 and the RF plug assembly plate 117. Similarly, the process of B plug cylinder 102 pushing B plate 116 and B plug 108 on it is the same as the process of A plug cylinder 101 pushing A plate 115 and A plug 107 on it, and will not be described again here.

[0050] like Figure 4As shown, the microwave module inspection platform of this embodiment also includes a module gripping arm 300 and a PLC controller. The module gripping arm 300 is installed on one side of the operating platform 100. A vision module 400 for image extraction of the microwave module is installed on the module gripping arm 300. The module gripping arm 300, vision module 400, A-plug cylinder 101, B-plug cylinder 102, RF clamping cylinder 103, adapter plug clamping cylinder 104, and video plug conversion cylinder 105 are all communicatively connected to the PLC controller. The vision module 400 can be an industrial camera used to photograph the microwave module and perform defect analysis through the PLC controller. The module gripping arm 300 can be a six-axis robot used to grip the microwave module, realizing automatic loading, unloading, and flipping of the microwave module. The PLC controller can realize information acquisition and control of the module gripping arm, cylinders on the operating platform, sensors, etc. The entire automated process control of the entire inspection platform and various devices and components on the operating platform can also be realized through a host computer. After the 300mm module gripper arm picks up and scans the barcodes, placing the microwave module on the testing platform, a real-time testing process begins. The host computer analyzes data collected from the power meter, programmable power supply, vector network analyzer, and module controller to determine the electrical performance indicators of the microwave module. Simultaneously, a vision module detects visual defects. If a defective microwave module is found, it is automatically powered off, and the gripper arm places it in the defective product area. Once the testing is complete and all indicators are within acceptable limits, the testing platform terminates the process, and the gripper arm returns the module to its original position. The entire testing process can be performed unattended. Furthermore, because the automatic visual inspection and electrical performance testing are performed simultaneously, the correlation between assembly quality and product electrical performance is recorded and evaluated in real time, allowing for timely adjustments. This significantly reduces the difficulty of later debugging, minimizes rework and repairs, and enhances the traceability of quality through full information technology.

[0051] The microwave module testing platform of this embodiment integrates various cylinders, RF plugs, adapters, RF connection mechanisms, etc. on the operating platform, which can simultaneously realize fully automatic power-on control and automatic electrical performance testing of microwave modules, replacing manual operation, ensuring continuity and reliability, and significantly improving testing accuracy and efficiency.

[0052] This embodiment of a microwave module testing method, implemented using the aforementioned microwave module testing platform, includes:

[0053] The module gripping arm 300 is used to grip the microwave module and place it at the barcode scanner position for QR code scanning. The barcode scanner sends the acquired QR code information to the PLC controller, and the module gripping arm 300 places the microwave module on the test platform 200.

[0054] The PLC controller parses the QR code information, determines the specific model of the microwave module, and controls the A plug cylinder 101, B plug cylinder 102, RF clamping cylinder 103, adapter plug clamping cylinder 104, and video plug conversion cylinder 105 to operate according to the specific model of the microwave module. The PLC controller is also used to control the vision module 400 to take pictures of the microwave module on the test platform 200, and to perform surface defect identification and analysis by extracting the surface image of the microwave module.

[0055] Furthermore, the PLC controller parses the QR code information, determines the specific model of the microwave module, and controls the operation of the A-plug cylinder 101, B-plug cylinder 102, RF clamping cylinder 103, adapter plug clamping cylinder 104, and video plug conversion cylinder 105 according to the specific model of the microwave module; specifically including:

[0056] When the QR code information is A1, the video plug conversion cylinder 105 extends, so that the connected conversion plug clamping cylinder 104 and conversion plug 106 correspond to the first video plug 110. After the video plug conversion cylinder 105 extends to the position, the A plug cylinder 101 extends and the B plug cylinder 102 retracts. After the A plug cylinder 101 and the B plug cylinder 102 are in position, the RF clamping cylinder 103 and the conversion plug clamping cylinder 104 extend simultaneously, so that the microwave module is connected to the RF connection mechanism 112, the A plug 107 and the RF plug 109 respectively. After the connection is successful, the microwave module is powered on for testing.

[0057] When the QR code information is A2, the video plug conversion cylinder 105 retracts, so that the connected conversion plug clamping cylinder 104 and conversion plug 106 correspond to the second video plug 111. After the video plug conversion cylinder 105 retracts into place, the A plug cylinder 101 extends and the B plug cylinder 102 retracts. After the A plug cylinder 101 and the B plug cylinder 102 are in place, the RF clamping cylinder 103 and the conversion plug clamping cylinder 104 extend simultaneously, so that the microwave module is connected to the RF connection mechanism 112, the A plug 107 and the RF plug 109 respectively. After the connection is successful, the microwave module is powered on for testing.

[0058] When the QR code information is B1, the video plug conversion cylinder 105 extends, so that the connected conversion plug clamping cylinder 104 and conversion plug 106 correspond to the first video plug 110. After the video plug conversion cylinder 105 extends to the position, the A plug cylinder 101 retracts and the B plug cylinder 102 extends. After the A plug cylinder 101 and the B plug cylinder 102 are in position, the RF clamping cylinder 103 and the conversion plug clamping cylinder 104 extend simultaneously, so that the microwave module is connected to the RF connection mechanism 112, the A plug 107 and the RF plug 109 respectively. After the connection is successful, the microwave module is powered on for testing.

[0059] When the QR code information is B2, the video plug conversion cylinder 105 retracts, aligning the connected conversion plug clamping cylinder 104 and conversion plug 106 with the second video plug 111. After the video plug conversion cylinder 105 extends to its position, the A plug cylinder 101 retracts, and the B plug cylinder 102 extends. After the A plug cylinder 101 and the B plug cylinder 102 are in position, the RF clamping cylinder 103 and the conversion plug clamping cylinder 104 extend simultaneously, connecting the microwave module to the RF connection mechanism 112, the A plug 107, and the RF plug 109 respectively. After successful connection, the microwave module is powered on for testing.

[0060] The power-on test specifically involves powering on the microwave modules after they have been loaded, turning on the radio frequency, and performing electrical performance tests on each channel of the microwave modules according to the established procedure. Simultaneously, a visual inspection is conducted, and this information is recorded in real time. During the inspection process, if an abnormal microwave module is found, the operating platform will automatically handle it by powering off the module and having the module gripper arm place it in the defective product area. Once the inspection is complete and all indicators are within acceptable limits, the operating platform initiates the unloading process. First, the PLC controller controls the cylinders to retract, and after the position sensors detect the correct positions, the module gripper arm retrieves the microwave module and places it back in its corresponding position, ending the inspection process.

[0061] Before the robot grabs the microwave module to the barcode scanner for QR code scanning, the process includes a vision module 400 on the module grabbing arm 300 visually photographing and locating the microwave module grabbing position, and sending the obtained microwave module position to the PLC controller. The PLC controller then controls the suction cup device 301 on the module grabbing arm 300 to complete the grabbing of the microwave module using a vacuum suction cup based on the microwave module position.

[0062] Furthermore, before the vision module 400 on the modular gripping arm 300 performs visual imaging and positioning of the microwave module's gripping position, the system also includes a self-check and initialization. Specifically, the host computer first sends an initialization command, and the modular gripping arm, PLC controller, and vision module begin to test communication. After successful communication, the initialization return-to-origin action is executed, the modular gripping arm returns to its initial position, and the PLC controller controls each cylinder on the operating platform to retract. After the execution is completed, the sensors of each cylinder detect whether they are in position. After they are in position, the initialization is completed and the system waits for the start command.

[0063] The microwave module testing method in this embodiment achieves fully automated loading and unloading, automatic power-on control, and simultaneous automatic appearance inspection and electrical performance testing of the microwave module testing process, realizing unattended operation for both processes. By replacing manual operation with machine vision inspection and automated testing, continuity and reliability are guaranteed, and inspection accuracy and efficiency are significantly improved.
