Problems solved by technology

Manual plugging and unplugging, manual-based, human-eye judgment and recognition, no machine-assisted operations
[0003] The current test operation method in the industry adopts a semi-automatic mode of manual plugging and judging test automation. Because the operator performs monotonous and repetitive work for a long time, visual fatigue and physical fatigue will occur, resulting in actions and thoughts. The beat does not match, and there is a missed test
In addition, some products have several identical ports next to each other. In this case, the operator has a high probability of plugging in the wrong port. There are many signal line plugs, and the operator often takes the wrong connector.
Manual work, there are missing tests, wrong interface / signal line connectors are inserted mixedly, which increases the working time

Embodiment example 1

[0027] Implementation case 1: When the test product enters the other position of the test station, the sensor will detect that the product is in place. The PLC will control the positioning device to lift the product for rough position correction S1; then the PLC control notifies the robot to move to the top of the interface, and the PLC controls the trigger The camera takes pictures, and the camera takes pictures and analyzes the coordinates and sends the position compensation data back to the PLC S2; the PLC sends the received data coordinates to the robot for position correction S3 before the interface is inserted; the robot automatically corrects the signal according to the position coordinates The plug is inserted into the interface S4; the PLC notifies the test software to start the test, and the test software sends the test result to the PLC S5; the PLC notifies the robot to pull out the plug S6; the robot pulls out the plug and goes to the second test station S7.

Embodiment example 2

[0028] Implementation Case 2: If Figure 6 As shown, at the beginning, the plug is inserted into the HDMI-1 interface, and the software signal source is switched. The test software detects and judges the HDMI-1 interface. After the test, it detects and judges the AV-IN interface. HDMI-2 interface, USB interface, HDMI-3 interface, high-definition image and computer P card image are detected and judged, among which HDMI-1 interface, AV-IN interface, HDMI-2 interface, USB interface, HDMI-3 interface, high-definition image It is qualified when the left side of the computer P card image is tested at 1Khz, and the right side is tested at 200hz.

[0029] The time for automatic plugging + unplugging of 7 interfaces is 21 seconds, the output is increased from the original 1600 machines / person / day to 1800 machines / station / day, and the production rate is increased by 12.5% / (for a single station production rate), which can be improved Yield. However, the missed test rate of the machine ...

Abstract

The invention discloses equipment and a method for a multi-interface test of an electronic product. The equipment comprises a control case cabinet; a bearing overload platform is arranged on the end surface of the control case cabinet; a left plugging / unplugging robot is fixedly mounted at the left side part of the bearing overload platform; a right plugging / unplugging robot is fixedly mounted at the right side part of the bearing overload platform; a supporting device is arranged at the rear part of the control case cabinet; a product angle correcting device is arranged between the supporting device and the control case cabinet; a multi-signal plug plugging / unplugging module is arranged at the upper part of the angle correcting device; a lifting device is arranged at the lower part of the supporting device; a product existence detecting sensor is arranged in the central position of the upper end surface of the lifting device. According to the equipment and the method for the multi-interface test of the electronic product, manpower is replaced by adopting intelligent robots and the equipment, so that the labour force can be reduced; therefore, the error rate of taking signal wire connectors by an operator and the error rate of plugging signal interfaces by mistake are reduced; the yield is improved; the quality rate is improved; the plugging / unplugging precision is improved; the efficiency is improved; processes are integrated and optimized; the operation is more convenient; resource waste is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of electronic product testing, in particular to a device and method for multi-interface testing of electronic products. Background technique [0002] At present, electronic products, such as TVs / laptops and other electronic products, have many sockets on the periphery. After forming the whole machine, it is necessary to connect VGA (Video Graphics Interface) / HDMI (High Definition Multimedia Interface) / USB (Universal Serial Bus Interface) / Cable TV socket and other interfaces for functional testing. The product to be tested is placed on the pallet, and the operator manually takes the test signal line, manually inserts it into the correct interface, and then starts the automatic detection step. After the test is completed, the plug is manually pulled out. Manual plugging and unplugging, manual-based, human-eye judgment and identification, no machine-assisted operations. [0003] The current test operation me...
