Problems solved by technology

Since each test station is independent, it is easy for production staff to miss the test, and the product will flow directly to the next test station or be packaged for shipment. In this way, when the product arrives at the customer, if there is a problem, it must be returned
The existing method is to attach a process barcode to the product, and let the staff manually mark the barcode every time they pass a test station, but this method is manual, and the staff will forget to mark it, or have not passed the test Just mark the station, there are also problems

Embodiment approach 1

[0019] Implementation Mode 1: Refer to figure 1 , an interlocking and error-proofing method for the testing process, A. Arranging different test stations according to the test sequence of the product to be tested, and then transmitting / recording the arrangement information into the database; B. The test information is transmitted / recorded into the database; C. The test station first compares the information of the product to be tested with the information in the database before testing or alarming. The database in the step A is set in the readable and writable memory chip EEPROM IC on the product. The test station can exchange data with the EEPROM IC. That is to say, after the product passes the test of each test station, first read the data of EEPROM IC to judge the test status of the previous test station. If everything is normal, the test station will perform the test action and record the test result in the specific address of EEPROM IC. If the product has not passed the...

Embodiment approach 2

[0020] Implementation mode two: refer to Figure 2-3 , an interlocking and error-proofing method for the testing process, A. Arranging different test stations according to the test sequence of the product to be tested, and then transmitting / recording the arrangement information into the database; B. The test information is transmitted / recorded into the database; C. The test station first compares the information of the product to be tested with the information in the database before testing or alarming. The database in the step A is set on the server, and the product to be tested is pasted with a product barcode before the test; before the step C, the test station also includes a step of obtaining product information by reading the product barcode. The test station is also provided with a scanner, which scans the product barcode to obtain product information. When the product under test passes through the first test station, a scannable barcode is attached. In this way, befo...

Abstract

The invention discloses an interlocking and fail-safe method during detection process. Different test stations are arranged according to the test sequence of products to be tested and then the arranging information is transmitted / recorded to a database. The test stations transmit / record the testing information of the products to be tested in the database. The test stations firstly compare the information in the products to be tested with that in the database and then test or alarm. The special test system of the method comprises different test stations and products to be tested. The products to be tested are provided with a read-write storage chip and the test stations can conduct data exchange with the chip. Or the system comprises different test stations, servers and products to be tested; the products to be tested are provided with bar codes; the servers are respectively connected with different test stations that are connected with scanners; and the test stations input the testinginformation and the product information obtained through scanning the bar codes to the servers. The system realizes the interlocking and fail-safe automation during production process, reduces the errors of staff and realizes the mutual communication of every test station.

Description

technical field [0001] The invention relates to a production line error prevention method and system thereof, in particular to an interlocking and error prevention system method and system of a detection process. Background technique [0002] In the existing production process, a product needs to pass through several testing stations before it can be packaged and shipped. Since each testing station is independent, it is easy for the production staff to miss the test, and the product flows directly to the next testing station or is packaged for shipment. In this way, when the product reaches the customer, it has to be returned if there is a problem. The existing method is to attach a process barcode to the product, and let the staff manually mark the barcode every time they pass a test station, but this method is manual, and the staff will forget to mark it, or have not passed the test Just mark the station, and there are also problems. Contents of the invention [0003] ...
