Description

Technical Field

[0001] The present invention relates to the technical field of radar TR components, and particularly to a test mechanism for radar TR components. Background Art

[0002] The radar TR component is the abbreviation of Transmit Receive, which originally means a signal processing component with both transmitting and receiving functions. It has absolute control in terms of regulation switching and power amplification. It can make the connected antenna transmit the signal after amplifying the power, and can also receive and amplify weak signals, making the signal transmission more stable.

[0003] When manufacturing and processing radar TR components, a series of tests and repairs are required. However, only using tools such as multimeters to conduct contact tests on the circuit board is difficult to simulate the state where the circuit board emits heat during long-term operation, resulting in a significant reduction in the detection effect. The feeding of the circuit board up and down is also quite inconvenient, greatly reducing the test efficiency. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a test mechanism for radar TR components. The positioning and pressing of the circuit board are achieved through a pressing device, thereby preventing the circuit board from shaking, and the test device enables diverse detection directions.

[0005] The present invention achieves the above technical objectives through the following technical means.

[0006] A test mechanism for radar TR components includes a frame body. The frame body is arranged on a base. A groove and a horizontal slot are formed in the frame body from bottom to top. Among them, a lead screw mechanism is arranged in the horizontal slot, and a sliding plate is arranged in the groove. When the lead screw mechanism works, it can drive the sliding plate to move left and right. Several first cylinders are arranged on the sliding plate, and an operating platform is arranged at the output end of the first cylinders. A circuit board and a pressing device are arranged on the operating platform. The pressing device is used to position and press the circuit board. A measuring device is also arranged directly above the operating platform. The measuring device is used to detect the voltage and current of the circuit board.

[0007] In the above solution, an L-shaped bracket is further arranged on the base. One end of the bracket is parallel to the frame body, and a measuring device is arranged on the parallel end of the bracket and the frame body.

[0008] In the above solution, the measuring device includes a chute, a movable plate, and a second cylinder. The chute is arranged on the bracket, and the chute is slidably connected to the movable plate. A multimeter and a second cylinder are arranged on the movable plate. Among them, the output end of the second cylinder is connected to a lifting plate, and a second motor is arranged below the lifting plate. The second motor is used to operate an electric pen.

[0009] In the above solution, a transverse groove is provided on the bracket, a fixing block is arranged in the transverse groove, a roller is rotatably arranged on the fixing block, the roller is driven by a third motor, and the fixing block is fixedly connected to the movable plate.

[0010] In the above solution, there are several groups of the pressing devices, which are symmetrically distributed at the four corners of the operating table.

[0011] In the above solution, the pressing device includes a pressing plate, a pull rod, a clamping frame and a spring; a track is provided on the operating table, a slider is arranged in the track, one end of the clamping frame is arranged on the slider, a pressing plate is arranged on the clamping frame, one end of the pressing plate is connected to the spring, the spring is arranged on the pull rod, and the pull rod with the spring end is placed in the clamping frame. When the pull rod is released, the spring pops out and settles the pressing plate after resetting to press the circuit board.

[0012] In the above solution, a through groove is further provided on the pull rod, the through groove is supported by the clamping frame, and the lower end of the through groove contacts the spring.

[0013] In the above solution, the lead screw mechanism includes a lead screw, a threaded block and a first motor; the threaded block is arranged on the lead screw, and when the first motor works, the lead screw drives the threaded block to slide.

[0014] In the above solution, the threaded block is connected to the push plate, a clamping block is arranged on the push plate, the clamping block is matched with a clamping groove, and the clamping groove is opened on the sliding plate.

[0015] In the above solution, the push plate slides along the longitudinal groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the testing mechanism for the performance and temperature relationship of the radar TR module not only realizes the convenient transfer of the circuit board, prevents the board from shaking, but also realizes the detection in multiple directions.

[0017] 1. In the present invention, a sliding plate is horizontally inserted between the grooves to fix the circuit board on the operating table. The first motor corresponding to the left side of the horizontal groove is started to horizontally move the threaded block and the push plate by the rotating lead screw. The left side of the push plate is fixed to the sliding plate with a clamping groove by a clamping block, which can guide the sliding plate to move left and right. At the same time, the operating table and the circuit board are synchronously lifted and lowered by the first cylinder, which is convenient for adjusting the position of the object to be detected and also convenient for moving left to load and unload materials.

[0018] 2. In the present invention, a clamping frame is fixed between the front and back of the top of the slider. Before the circuit board is placed on the operating table, the pull rods are respectively pulled on both sides, and the pressing plates installed at the bottom of the pull rods are vertically lifted along the through grooves. After both sides of the circuit board are respectively located between the pressing plate and the operating table, the pull rods are released. After the spring resets, it pops out and settles the pressing plate to prevent the circuit board from shaking during detection, which affects the data accuracy. After the detection is completed, the pull rods are pulled up again and the circuit board is unloaded.

[0019] 3. The present invention installs a movable plate in the sliding groove. By starting the third motor outside the fixed block, the roller is forced to rotate in the fixed block, and the movable plate is forced to translate left and right along the sliding groove. The lifting plate is lifted or lowered by the second cylinder, and in cooperation with the electric pen operated by the second motor in the two side frames, the left and right orientations and the horizontal position of the electric pen are adjusted, so as to cover the circuit board meticulously for voltage and current detection, thereby expanding the coverage range of the detection mechanism.

[0020] 4. The present invention laterally inserts a sliding plate between the grooves to fix the circuit board on the operating table. By starting the first motor corresponding to the left side of the horizontal groove, the screw rod rotates to translate the threaded block and the push plate left and right. The left side of the push plate is fixed to the sliding plate with a card slot by means of a card block, which can guide the sliding plate to translate left and right. The operating table and the circuit board and other objects are also lifted and lowered synchronously by the first cylinder, which not only facilitates the adjustment of the position of the object to be detected, but also facilitates the leftward movement for feeding and discharging, thus solving the problem of inconvenient detection and feeding.
