Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to a semi-open positioning testing machine for testing microwave components. Background Art

[0002] The traditional manual microwave component test environment is usually set up by transmitting a specified test signal from a signal source, connecting the microwave component to be tested through a cable connector, and then using test instruments such as oscilloscopes, spectrum analyzers, power meters, and vector network analyzers to read the feedback signal and obtain measurement values. The measured values ​​are then used to determine whether the component meets the qualification standards and make a component qualification judgment.

[0003] During the measurement process, there are two factors that have a greater impact on the measurement accuracy: the coupling of the cable connector; the length of the test cable. The cable and connector can be selected according to the focus of the test project. Stable test cables and test connectors for different test frequencies are used. Regarding test cables, RF-specific armored cables are commonly used. The longer the test cable, the greater the signal loss. To achieve the same measurement accuracy for cables of different lengths, the longer the line, the more expensive it is, and the larger the outer diameter is. If you want to achieve automated testing of microwave components, the shorter the cable, the higher the test accuracy. Semi-open test machines can well solve the problem of cable length between microwave components and signal source instruments.

[0004] Traditional semi-open test benches typically utilize physical protection (guardrails, protective nets) and mechanical protection (limit switches, emergency stop buttons). These disadvantages include the following: physical protection not only restricts the operator's field of view and range of movement, increasing operational complexity, but also potentially impacting test accuracy and efficiency. Mechanical protection, on the other hand, is slow to respond to high-speed or sudden hazards and is prone to failure due to long-term use and improper operation, failing to fully guarantee the safety of the testing process.

[0005] Therefore, in order to solve the above problems, it is necessary to design a semi-open positioning test machine for testing microwave components. Utility Model Content

[0006] The purpose of the utility model is to provide a semi-open positioning test machine for testing microwave components, so as to solve the technical problems mentioned in the background technology.

[0007] In order to solve the above technical problems, the present invention provides a semi-open positioning test machine for testing microwave components, comprising:

[0008] A mounting platform and a three-axis motion module arranged on the mounting platform, which includes: an X-axis motor, a Y-axis motor, and a Z-axis motor;

[0009] Protective plates are provided on the top of both sides of the mounting platform;

[0010] Infrared grating, set on the protective plate, is used to detect whether there is an object entering the predetermined safety area;

[0011] The main control module is electrically connected to the X-axis motor, Y-axis motor, Z-axis motor and infrared grating;

[0012] The main control module is suitable for receiving the detection signal uploaded by the infrared grating, and controlling the start and stop of the X-axis motor, the Y-axis motor and the Z-axis motor according to the detection signal.

[0013] Furthermore, the infrared grating includes: a light emitter arranged on one protective plate and a light receiver arranged on the other protective plate; wherein

[0014] The light emitter and the light receiver are electrically connected to the main control module; and

[0015] The light receiver is suitable for receiving the infrared light emitted by the light emitter;

[0016] When the light is not blocked, the light receiver will receive the light normally and output a light-through signal to the main control module;

[0017] When the light is blocked, the light receiver will not be able to receive the light and will output a light blocking signal to the main control module.

[0018] Furthermore, a cabinet is provided at the bottom of the installation platform;

[0019] The top of the cabinet is provided with a three-color light;

[0020] The three-color light is electrically connected to the main control module.

[0021] Furthermore, the bottom array of the cabinet is provided with at least four Forma wheels.

[0022] Furthermore, a mounting frame is provided on the outer side of the protective plate;

[0023] The light emitter and the light receiver are respectively mounted on corresponding mounting frames.

[0024] The beneficial effects of the utility model are:

[0025] (1) The present invention can effectively detect whether an object enters a predetermined safety zone by installing an infrared grating on the protective plate. Once an object (such as the operator's hand or other unexpected object) enters the zone, the infrared grating will immediately send a detection signal to the main control module, and the main control module will respond quickly to control the X-axis motor, Y-axis motor and Z-axis motor to stop running.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention. Example 1

[0036] like Figure 1 、 Figure 2 As shown, this embodiment provides a semi-open positioning test platform for testing microwave components, including:

[0037] The mounting platform 1 and the three-axis motion module 2 arranged on the mounting platform 1 include: an X-axis motor 21, a Y-axis motor 22 and a Z-axis motor 23; a protective plate 3, arranged on the top of both sides of the mounting platform 1; an infrared grating 4, arranged on the protective plate 3, for detecting whether an object enters a predetermined safety area; a main control module, electrically connected to the X-axis motor 21, the Y-axis motor 22, the Z-axis motor 23 and the infrared grating 4; wherein the main control module is suitable for receiving the detection signal uploaded by the infrared grating 4 and controlling the start and stop of the X-axis motor 21, the Y-axis motor 22 and the Z-axis motor 23 according to the detection signal; wherein the three-axis motion module 2 adopts but is not limited to a gantry-type three-axis motion module; wherein the protective plate 3 adopts but is not limited to a PC (polycarbonate) transparent protective plate to facilitate observation of the test environment from the side; wherein the X-axis motor 21, the Y-axis motor 22 and the Z-axis motor 23 adopt but are not limited to servo motors; wherein the main control module adopts but is not limited to a PLC.

[0038] In this embodiment, by installing the infrared grating 4 on the protective plate 3, it is possible to effectively detect whether an object enters the predetermined safety area. Once an object (such as the operator's hand or other unexpected object) enters the area, the infrared grating 4 will immediately send a detection signal to the main control module, and the main control module will respond quickly to control the X-axis motor 21, Y-axis motor 22 and Z-axis motor 23 to stop running. At the same time, when the object leaves the predetermined safety area, the infrared grating 4 will immediately send another signal to the main control module, and the main control module will respond quickly to control the X-axis motor 21, Y-axis motor 22 and Z-axis motor 23 to continue running, thereby preventing the occurrence of accidents and significantly improving the safety and efficiency of the test process.

[0039] The infrared grating 4 includes: a light emitter 41 arranged on any protective plate 3 and a light receiver 42 arranged on the other protective plate 3; wherein the light emitter 41 and the light receiver 42 are electrically connected to the main control module; and the light receiver 42 is suitable for receiving the infrared light emitted by the light emitter 41; when the light is not blocked, the light receiver 42 will normally receive the light and output a light-transmitting signal to the main control module; when the light is blocked, the light receiver 42 will not be able to receive the light and output a light-blocking signal to the main control module.

The instrument needs to be visually observed during the testing and debugging process. If a closed test machine is used, the instrument will be blocked, or the instrument display area needs to be installed on the back of the standard cabinet, which will cause trouble for the operator to observe and debug, and will take up more physical space. The semi-open structure does not affect the instrument debugging and observation on the same side of the test machine.
