Problems solved by technology

[0003] The existing radar assembly adopts the traditional manual assembly mode. Manual assembly is easy to cause invisible damage to the PCBA, affecting the product qualification rate, and the production cost is high, the production efficiency is low, and the quality of the assembled radar products is not uniform.
The existing production line models in the market usually have discrete assembly, testing, and aging stations, and the flexibility of the production line is poor. Many product models are difficult to manufacture compatiblely. The entire production line does not have overall process continuity and low efficiency. Manual online assistance is still required.
[0004] In order to ensure the factory quality and consistency of radar products, it is necessary to perform a performance test on each assembled radar to test the radar’s horizontal viewing angle, pitch angle, resolution and other parameters. This test is usually carried out by establishing a radar darkroom. The design of the darkroom Depending on the parameters that need to be measured by the product, most of the existing performance tests in the market are offline black boxes, and there is no dark room for online testing

Embodiment 1

[0043] A millimeter-wave radar automated intelligent production line, as attached Figure 1~3 As shown, it includes 15 units in turn: cover plate feeding machine (1), PCBA plate feeding machine (2), PCBA board marking machine (3), PCBA board and cover plate assembly machine (4), heat conduction sheet machine (5), waterproof base feeding machine (6), waterproof base marking machine (7), pressure holding machine (8), waterproof base assembly machine (9), air tightness testing machine (10), double-layer transportation Belt conveyor (11), aging box feeder (12), aging box (13), finished product discharging machine (14), dark box test unit (15), the automatic intelligent production line of millimeter wave radar adopts U-shaped line Layout, the cover board feeder (1), PCBA board feeder (2), PCBA board marking machine (3), PCBA board and cover board assembly machine (4), heat conducting sheet paste machine (5), The waterproof base feeding machine (6), the waterproof base marking mach...

Embodiment 2

[0074] as attached Figure 22 As shown, the dark box test can also adopt the mode of off-line test to set up a dark box test room. The dark box test room includes a dark room. Personnel enter and exchange radar products. The radar products are placed on the anechoic radar turntable module (16-2). The darkroom radar turntable module (16-2) is designed on the same principle as the radar turntable module (15-2). The darkroom radar turntable module (16-2) is installed on the turntable track (16-6), and the turntable track (16-6) is 0.5 to 1 meter long, and other parts of the darkroom linear slide rail (16-3), darkroom Arc-shaped slide rail (16-4), darkroom target simulator (16-5) and linear slide rail (15-3), darkroom arc-shaped slide rail (15-4), darkroom target simulator (15-5) The principle and structure are the same, and the anechoic chamber can simulate and test the performance of the radar in motion by setting the turntable track (16-6).

Abstract

The invention provides a radar camera obscura testing device. The device comprises a sealed box body, and wave-absorbing materials are completely laid on the inner wall of the sealed box body; the radar camera obscura testing device comprises at least one radar turntable module, radar products are placed in the at least one radar turntable module. Each radar turntable module comprises a clamp. A clamping device and a power-on interface are arranged in the clamp; the clamping device automatically clamps a radar product. The power-on interface is connected with the circuit board and the electricwire circuit; automatic power-on is realized, and radar data is sent to the industrial personal computer; and a linear sliding rail, an arc-shaped sliding rail and a target simulator are arranged inthe sealed box body. The target simulator is connected to the linear sliding rail or the arc-shaped sliding rail through a sliding rod; the radar product detects movement of a target and feeds back adetection result to the industrial personal computer, actual movement parameters of the target are preset and controlled by an industrial personal computer program, information is transmitted to the driving motor connected to the sliding rod through a circuit, and the detection performance of the radar can be obtained through comparison and analysis.

Description

technical field [0001] The invention relates to the technical field of radar automatic testing and production, in particular to a radar black box testing device. Background technique [0002] The millimeter-wave radar automatic intelligent production line is mainly used in the assembly and testing of radar sensors.
