Description

Technical Field

[0001] The utility model relates to the technical field of ECU function testing, in particular to an automatic production line for ICT and FCT testing of ECU. Background Art

[0002] ECU-TEST is a software tool for embedded system test and verification developed by TraceTronic GmbH located in Dresden, Germany. Since its first release in 2003, the software has become the standard tool for automotive ECU development and has gradually become the standard tool for heavy machinery and industrial automation development. The software originated from a project research on the systematic testing of a control unit, which laid the foundation for TraceTronic GmbH separated from Dresden University of Technology. ECU-TEST aims to standardize, evaluate, solve and archive test cases. Thanks to a large number of automated test methods included in the software, all necessary functions of test cases such as creation, solution and evaluation functions can be successfully achieved.

[0003] The existing ECU function testing has the following defects:

[0004] The main production method of the existing ECU function testing (FCT) is to divide the entire test process into several workstations, arrange several operators at each workstation for manual testing, and then add corresponding inspection tools between some workstations for quality inspection through personnel operation. This method consumes a large amount of manpower, has low efficiency, and is prone to unstable product quality, ineffective quality control, and difficult preservation of production data and test results, which is not conducive to product traceability. Therefore, a solution needs to be given. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1 , the embodiments of the present invention provide a technical solution: an automatic production line for ICT and FCT testing of ECUs, including a control cabinet 1, a six-axis manipulator 2, a storage station 3 for the ECU to be tested, an ECU positioning and code scanning station 4, an empty tray storage station 5, and an indexing table 14.

[0019] It is solved that the indexing plate 14 has a circular structure. At the top of the indexing plate 14, there are respectively an ECU loading and unloading station 6, a spare station 7, a test program burning station 8, a DMM test station 9, an oscilloscope test station 10, and a formal program burning station 11. The ECU loading and unloading station 6, the spare station 7, the test program burning station 8, the DMM test station 9, the oscilloscope test station 10, and the formal program burning station 11 are distributed in an annular equidistant manner. ECU loading and unloading station 6: The six-axis manipulator 2 takes the ECU from the ECU positioning and code scanning station 4 and sends it to the ECU loading and unloading station 6 on the indexing plate 14, and the indexing plate 14 rotates to the next station. Test program burning station 8: After the ECU to be tested is transferred to the test program burning station 8, the needle board presses down to start the program burning work. DMM test station 9: After the ECU with the program burned is transferred to the DMM test station 9, the needle board presses down to measure items such as current and voltage. Oscilloscope test station 10: After the ECU is transferred to the oscilloscope test station 10, the needle board presses down to measure items related to the oscilloscope. Formal program burning station 11: After the ECU is transferred to the oscilloscope test station 10, the needle board presses down to burn the formal program of the ECU. After the formal program of the ECU is burned, it rotates to the ECU loading and unloading station 6.

[0020] Furthermore, on the right side of the six-axis manipulator 2, there are respectively an OK ECU storage station 12 and an NG ECU storage station 13. The OK ECU storage station 12 is located in front of the NG ECU storage station 13.

[0023] Working principle: During operation, the six-axis manipulator 2 picks up the ECU. After the equipment is started, the operator places a stack of trays containing ECUs into the storage station 3 for the ECUs to be tested. The servo lifting device inside the mechanism will automatically send the ECU tray to the picking position. The six-axis manipulator 2 will move to the picking position to pick up the ECU. Before picking up the part, the vision system judgment device 15 installed at the end of the six-axis manipulator 2 will judge whether there is an ECU at the picking position. The barcode reader 16 at the end of the six-axis manipulator 2 can read the QR code on the ECU and transmit it to the control system. ECU loading and unloading station 6: The six-axis manipulator 2 picks up the ECU from the ECU positioning and barcode scanning station 4 and sends it to the ECU loading and unloading station 6 on the indexing table 14. The indexing table 14 rotates to the next station. Test program burning station 8: After the ECU to be tested is transferred to the test program burning station 8, the needle board presses down to start the program burning work. DMM test station 9: After the ECU with the program already burned is transferred to the DMM test station 9, the needle board presses down to measure items such as current and voltage. Oscilloscope test station 10: After the ECU is transferred to the oscilloscope test station 10, the needle board presses down to measure items related to the oscilloscope. Formal program burning station 11: After the ECU is transferred to the oscilloscope test station 10, the needle board presses down to burn the formal program of the ECU. After the formal program of the ECU is burned, it rotates to the ECU loading and unloading station 6. The six-axis manipulator 2 picks up the ECU from this station and places the ECU into the OK ECU storage station 12 or the NG ECU 13 storage station according to the final test result.

The problem solved by the utility model is that the main production method of the existing ECU functional test (FCT) is to divide the entire test process into several stations, arrange several operators at each station to perform manual testing, and then add corresponding inspection tools between certain stations to perform quality inspections through personnel operation. This method consumes a lot of manpower and is inefficient. At the same time, it is easy to cause unstable product quality and the quality cannot be effectively controlled.
