Problems solved by technology
[0004] 1) Robots are used to replace human operations to realize automated production, but the cost of transformation in this way is high, and the debugging cycle is relatively long
[0005] 2) Transform the traditional ICT and FCT to have the function of online testing. At present, the production line is generally set up one by one in series. There are several problems in this way: 1. When one of the machines needs to be debugged and maintained , the whole production line had to stop; 2. When the test time of ICT and FCT is different, only the machine with a long time can be used as the production beat, which makes the equipment of the whole production line unable to be effectively used and inefficient; 3. In order to To solve the problem of inefficiency in the second point, adding some test machines with the same function will make the transfer of PCBA between machines very complicated

Embodiment Construction
[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0052] like Figure 1-Figure 14 As shown, a method for realizing multi-machine parallel testing of ICT and FCT, the test section includes: a rotary distribution table 2 with a conveyor track 1, a rotatable conveyor track 1, a first online testing machine 3 with a conveyor track 1 and Second in-circuit testing machine 4 with conveyor track 1.
[0053] The action process of the test section includes the following steps:
[0054] 1) The PCBA6 on the PCBA tray 5 is transferred from the front station to the rotary distribution table 2 through the conveying track 1, and the PCBA tray 5 is transferred to the rotary distribution table 2. After the PCBA tray 5 is in place, the rotary distribution table 2 rotates 90° to distribute the PCBA through the conveying track 1 The tray 5 goes...

The invention provides a method for realizing ICT and FCT multi-machine parallel testing. The action process of a test section comprises the following steps that 1) a PCBA tray is conveyed to a rotary distribution table from a previous working position through a conveying track, the PCBA tray is conveyed to the rotary distribution table, the PCBA tray is arranged in place and then the rotary distribution table rotates for 90 degrees to distribute the PCBA tray to a first online test machine, the first online test machine detects the in-place state of the PCBA tray and then starts testing, and the rotary distribution table returns to wait for receiving the next PCBA tray to be tested; and 2) the rotary distribution table receives the PCBA tray again and then rotates for 90 degrees to distribute the PCBA tray to a second online test machine. According to the method for realizing ICT and FCT multi-machine parallel testing, cost can be reduced, and a production line can be formed through connection of the original independently produced ICT and FCT so that automatic production can be realized, the machines of different beats can be effectively utilized and the use efficiency of the machines is enabled to be optimal.
Description
technical field [0001] The invention relates to a method for realizing multi-machine parallel testing of ICT and FCT. Background technique [0002] In the electronics manufacturing industry, the production of PCBA is an essential link. In the production process of PCBA, ICT and FCT are also necessary inspection procedures. Usually, one section of ICT and at least one section of FCT (or multiple sections of FCT) will be passed through. Most of the ICT and FCT are in single-machine semi-automatic mode. Machines need to be equipped with operators to work manually, and cannot realize on-line automated production, which seriously hinders the automation process of the PCBA production industry. [0003] There are two commonly used solutions for the automation transformation of ICT and FCT: [0004] 1) Robots are used to replace human operations to realize automated production, but the cost of transformation in this way is high, and the debugging cycle is relatively long. [0005...
