  • Detail

Recently, the prototype of the assembly system (unit production system) using multi axis robots developed by Mitsubishi Electric and other companies has not been released to the public. This kind of robot has the function of picking flexible objects such as cables and inserting their top connectors into the substrate. The combination of the two 6-axis robots played an active role and used the devices independently developed by the company, including three-dimensional sensors that can identify flexible objects at high speed, and force sensors that can accurately identify the insertion status of joints and screws. The assembly time was equivalent to that in the past when unit production was carried out only by manual operation

the motor amplifier assembled by the system prototype is a motor amplifier which uses cables to connect each base plate and screws to fix the outer cover. First, sort out a cable from the bulk cable, and insert a connector of the cable into the first base plate pre fixed on the chassis. However, the control function of EC experimental machine is mainly to complete various controls of the experimental machine by PC based on the undetermined communication between PC and lower computer. Oncore is expanding the function of its thermohex technology. After that, the second substrate is fixed on the first substrate with screws, and then another connector is inserted. The test results of Jinan gold assay digital impact tester are accurate. The last process is to add an outer cover and fix it with screws. First, the first robot (hereinafter referred to as robot a) picks out the cables from the bulk cables and installs them on the fixture, and then the second robot (hereinafter referred to as robot b) inserts the connector into the base plate

the three-dimensional sensor is set at the top of robot a and near the area for sorting. The camera can be used to shoot near-infrared light and recognize three-dimensional shapes. It has the performance of position accuracy of 1mm and resolution of 0.5mm, and the recognition time is less than 1 second. Moreover, in order to be installed at the top of the robot, the sensor is small and lightweight. The volume of the fuselage is 300ml and the weight is about 500g

the system prototype also has the function of identifying falling, connector or screw insertion errors and automatic recovery when picking cables. The information provided by the three-dimensional sensor and force measuring sensor can be used to improve the operation efficiency through long-term automatic operation

at present, it has been confirmed that the time required for assembly is equivalent to that for unit production relying on manual operation, but the future task is to verify the cost
