Abstract

The invention discloses an FCT test fixture and method, the FCT test fixture is provided with a test device, the test device comprises an MCU main control circuit, and a power supply module, an infrared emission circuit, a current and voltage detection module, a peripheral function test port module and an alarm circuit which are electrically connected with the MCU main control circuit; the peripheral function test port module comprises one or more test connection circuits, each test connection circuit comprises a connection terminal, and each pin of the connection terminal is grounded through a resistor and a voltage-regulator tube respectively; and according to the invention, the test can be carried out according to the test requirements of a plurality of different functional modules of the circuit board to be tested, whether each functional module circuit of the circuit mainboard of the sweeper is normal or not can be tested and judged in a short time, and the working efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of FCT testing, in particular to an FCT testing fixture and method. Background technique [0002] With the continuous development of artificial intelligence technology, more and more smart homes have emerged as the times require. The emergence of sweepers has gradually replaced manual cleaning and has been accepted by more and more people. Sweeping robot (abbreviated as sweeping machine), also known as automatic cleaning machine, intelligent vacuum cleaner, robot vacuum cleaner, etc., is a kind of smart household appliances and is widely used at present. The main working process of the existing sweeping robot is as follows: the sweeping robot moves on the ground and absorbs ground dust and other garbage into its own dust box, thereby completing the function of cleaning the ground. Then, the user needs to press the dust box release button on the surface of the sweeping robot at regular intervals to take out the dust b...
