Description

Technical Field

[0001] The present invention relates to the technical field of pipeline production test systems, and particularly relates to a pipeline production test system and a method for solving anti-fooling problems. Background Art

[0002] Before a product is packaged, it needs to be tested for its quality performance and the like at several test stations on a production line. After passing the tests, it is then packaged. For different product tests, they need to be carried out on different production lines. In the past, each test device at each test station on each production line was directly connected to a server by signal. Therefore, the server needed to have a large number of access ports, which made the server overloaded and prone to crashing, thus easily leading to problems such as signal transmission errors or omissions. Therefore, improvements are needed. Summary of the Invention

[0003] The purpose of the present invention is to provide a pipeline production test system and a method for solving anti-fooling problems to solve the problems mentioned in the background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A pipeline production test system includes a server and several production lines. Along the conveying direction on each production line, there are several test stations, as well as a packaging station arranged at the end of the production line; several test devices are provided on each test station; a first barcode scanning device is provided on each test device; a packaging device and a computer are provided on the packaging station; a second barcode scanning device is provided on the packaging device; first wireless data transceiver devices are provided on both the test device and the packaging device; a second wireless data transceiver device and a host computer software system are installed on the computer; the host computer software system is signal-connected to the server.

[0006] A method for solving anti-fooling problems using the above pipeline production test system. Each test device and packaging device has a specific device ID, and the method includes the following steps:

[0007] Step 1: A product with a running code is sent to a test device, and the running code of the product is obtained through the first barcode scanning device on the test device.

[0008] Step 2: The running code obtained in Step 1, together with the device ID of the test device in Step 1, is sent in a fixed sequence by the first wireless data transceiver device on the test device to the second wireless data transceiver device at the packaging station.

[0009] Step 3: After the second wireless data transceiver device at the packaging workstation receives the transmitted data in Step 2, the host computer software system retrieves data from the server according to the device ID and serial number, determines the test status of the current product, and gives an instruction on whether to continue the test. The instruction is transmitted to the test device in Step 1 through the second wireless data transceiver device;

[0010] Step 4: After the test device in Step 1 receives the instruction sent by the second wireless data transceiver device, it performs one of the following two operations: (1) If it is judged as OK, the test is started, and the device ID, serial number, and test result are packed and sent to the second wireless data transceiver device at the packaging workstation. The host computer software system processes the data and stores it in the server; (2) If it is judged as NG, the test is aborted and a defect warning is given;

[0011] Step 5: After it is judged as OK and the test is completed, the product flows into the next test device, and the processes of Steps 1 to 4 are repeated until the product reaches the packaging workstation. The product serial number information is obtained through the second barcode scanning device, and the serial number and the device ID on the packaging device are sent to the second wireless data transceiver device through the first wireless data transceiver device on the packaging device. The host computer software system also retrieves the test result from the server according to the serial number and the device ID, and finally gives an instruction on whether to execute the packaging command.

[0012] The beneficial effects of the present invention are as follows:

[0013] In the present invention, data transmission is carried out between each production line and the first wireless data transceiver devices at the test workstation and the packaging workstation through the second wireless data transceiver device at the packaging workstation. Only one point of the host computer software system is connected to the server, which can greatly reduce the burden on the server, reduce the error rate, and thus play a role in preventing mistakes and omissions.

[0014] Figure 1 is the overall structure diagram of the present invention. Detailed Embodiments

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] As Figure 1As shown in the figure, a pipeline production test system includes a server and several pipelines. Along the conveying direction of each pipeline, there are several test workstations, and a packaging workstation is arranged at the end of the pipeline; several test devices are provided on each of the test workstations; a first barcode scanning device is provided on each of the test devices; a packaging device and a computer are provided on the packaging workstation; a second barcode scanning device is provided on the packaging device; first wireless data transceiver devices are provided on both the test devices and the packaging device; a second wireless data transceiver device and a host computer software system are installed on the computer; the host computer software system is in signal connection with the server.

[0017] The pipelines are divided into Pipeline 1, Pipeline 2, Pipeline 3... Pipeline X;

[0018] The test workstations on each pipeline are divided into Test Workstation 1, Test Workstation 2, Test Workstation 3... Test Workstation N;

[0019] The test devices on each test workstation are divided into Test Device 1, Test Device 2... Test Device N;

[0020] Each test device and packaging device has a specific device ID. Information of all device IDs is recorded in the server. According to the device ID number, it can be known which device on which workstation of which pipeline the device is located.

[0021] A method for preventing mistakes by using a pipeline production test system includes the following steps:

[0022] Step 1: A product with a serial code is sent to a test device, and the serial code of the product is obtained through the first barcode scanning device on the test device;

[0023] Step 2: The serial code obtained in Step 1 sends the serial code and the device ID of the test device to the second wireless data transceiver device at the packaging workstation in a fixed sequence through the first wireless data transceiver device on the test device in Step 1;

[0024] After the second wireless data transceiver device at the packaging workstation receives the data transmitted in Step 2, the host computer software system retrieves data in the server according to the device ID and the serial code, judges the test status of the current product, and gives an instruction on whether to continue the test, and transmits the instruction to the test device in Step 1 through the second wireless data transceiver device;

[0025] Step 4: After the test equipment in Step 1 receives the instruction sent by the second wireless data transceiver, it performs one of the following two operations: (1) If it determines OK, it starts the test and packs and sends the device ID, serial number, and test result to the second wireless data transceiver at the packaging workstation. The host computer software system processes the data and stores it in the server; (2) If it determines NG, it aborts the test and gives a defect warning.
