Embodiment 1

[0085] as attached figure 1 The shown industrial robot drive board detection card, an industrial robot drive board detection card, is characterized in that it includes a detection card 1, a single-chip microcomputer 3, a multi-channel analog switch 2, a gold finger and a test signal buffer 4; wherein,

[0086] The single-chip microcomputer 3 , the multi-channel analog switch 2 and the test signal buffer 4 are inserted into the chip holder preconfigured on the detection card 1 ; the multi-channel analog switch 2 and the test signal buffer 4 are electrically connected to the single-chip microcomputer 3 . connection; the multi-channel analog switch 2 and the test signal buffer 4 are electrically connected;

[0087] The detection card 1 is inserted into the preset card slot of the tested drive board 10 through the golden finger 6; wherein,

[0088] When the multi-channel analog switch 2 is turned on, the single chip 3 sends a PWM motor drive signal to the tested drive board 10, a...

Embodiment 2

[0097] As an embodiment of the present invention: the multi-channel analog switch 2 is composed of a plurality of analog switches; the plurality of analog switches respectively control the plurality of axis joint motors connected to the detected drive board 10, and drive the motor. The analog signal of the shaft joint motor is converted into a digital signal and transmitted to the detection card 1; in the present invention, the multi-channel analog switch 2 corresponds to a plurality of shaft joint motors, and different analog switch signals control different motors.

[0098] There are multiple test signal buffers 4 , the multiple test signal buffers 4 are respectively connected with multiple analog switches, and the test signal buffers correspond to the analog switches in the multi-channel analog switches 2 .

[0099] The multi-channel analog switch 2 of the present invention is constituted by a plurality of analog switch chips, the analog chip switch is connected with the tes...

Embodiment 3

[0103] As an embodiment of the present invention: the faults include phase faults, main circuit relay faults and IGBT module faults; wherein,

[0104] The phase faults include phase loss faults and undervoltage faults;

[0105] The main circuit relay failure is the main circuit relay disconnection failure; when the main circuit relay is disconnected, the detected drive board 10 does not start.

[0106] The IGBT module fault is an IGBT module overtemperature fault.

[0107] The main fault points of the drive board detected by the present invention are the phase of the input power supply, the disconnection of the main circuit relay, and the temperature and current of the IGBT. Therefore, the present invention comprehensively detects the tested drive board from three types of faults: phase fault, main circuit relay fault and IGBT module fault.

[0108] In one embodiment, the rectifier circuit is used for external three-phase power supply; wherein, the tested drive board 10 of t...

Abstract

The invention provides a detection card for an industrial robot drive board. It includes a detection card, a single-chip microcomputer, a multi-channel analog switch, a golden finger and a test signal buffer; wherein, the single-chip microcomputer, a multi-channel analog switch and a test signal buffer are inserted into a pre-configured chip socket on the detection card; the The multi-channel analog switch and the test signal buffer are electrically connected to the single-chip electromechanical device; the multi-channel analog switch is electrically connected to the test signal buffer; the detection card is inserted into the preset card slot of the tested drive board through the golden finger; Wherein, when the multi-channel analog switch is turned on, the single-chip microcomputer sends a PWM motor driving signal to the checked driving board, and receives a feedback signal from the checked driving board to determine whether the checked driving board is faulty.

Description

technical field [0001] The invention relates to the technical field of industrial robot driving board detection, in particular to an industrial robot driving board detection card. Background technique [0002] In recent years, my country has become the market with the fastest growing number of industrial robots and the largest demand in the world. Corresponding to the growth in sales, robot replacement has also maintained a rapid growth trend. After a large number of sampling of industrial robots, the maintenance and repair services of industrial robots and the industry have changed. With the expiration of the warranty, the maintenance and repair costs of the original factory are too high, and the general maintenance companies in the industrial robot maintenance and repair market are faced with independent research and development. Equipment requirements, this test card brings convenience to the maintenance and repair industry of industrial robots. The drive board of the e...
