DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] It should be noted that, although the functional modules are divided in the system schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the system or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0020] refer to Figure 1 , Figure 1 This is a flow chart of the steps of the quality inspection method for printed circuit boards. The quality inspection method for printed circuit boards is mainly performed by a smart device. When the smart device is running, the steps that can be performed include: Step 1: Print a marking symbol on the first printed circuit board of the target batch to be tested, and mark the first printed circuit board as the target marking board; The intelligent device controls the screen printing device so that the screen printing device can find the first board in the target batch of printed circuit boards to be tested, and screen print the marking symbol on the first board. The first board refers to the first board of the target batch of printed circuit boards to be tested. The target batch of printed circuit boards to be tested are sorted according to the order of testing, wherein the printed circuit board ranked first is the first board.

[0021] The marking symbol records the quantity and identification number of the target batch of printed circuit boards to be inspected.

[0022] Step 2: Obtain information of the marking symbol on the target marking plate to determine the quantity and identification number of the target batch of printed circuit boards; record the quantity as the target quantity, and record the identification number as the target identification number.

[0023] After the silk screen printing of the first board of the target batch of printed circuit boards to be inspected is completed. When the target batch of printed circuit boards to be inspected needs to be quality inspected, the intelligent device can obtain the marking symbol and obtain the quantity and identification number of the target batch of printed circuit boards therefrom. Wherein, in some further specific embodiments, the information of the marking symbol on the target marking board is obtained to determine the quantity and identification number of the target batch of printed circuit boards, specifically including: the intelligent device controls the image acquisition device to capture the image of the position of the marking symbol of the target marking board through the image acquisition device. The intelligent device can parse the image to determine the quantity and identification number of the target batch of printed circuit boards through the image. Wherein, for the convenience of description, the number of the target batch of printed circuit boards obtained is recorded as the target number. The identification number of the target batch of printed circuit boards obtained is recorded as the target identification number.

[0024] Step 3: Determine the items that need quality inspection according to the target identification number, and record the items as target quality inspection items.

[0025] By obtaining the target number, it is possible to know how many printed circuit boards need to be inspected at present. By obtaining the target identification number, the items of quality inspection required for the current printed circuit can be determined according to the target identification number. In some further specific embodiments, the items that need to be inspected according to the target identification number specifically include: The smart device sends the obtained target identity number to the first server through the network. The first server stores a data table of the relationship between the identity number and the quality inspection items in advance. After receiving the target identity number, the first server can query the data table of the relationship between the identity number and the quality inspection items. The quality inspection item corresponding to the target identity number can be found by looking up the table. The first server feeds back the quality inspection item obtained by the query, so that the smart device obtains the quality inspection item. For the convenience of description, the quality inspection item is recorded as the target quality inspection item. This target quality inspection item is the quality inspection item of the printed circuit board that currently needs to be inspected.

[0026] Step 4: Determine the operation script of the automated testing device according to the target quality inspection item, and record the operation script as the target operation script.

[0027] After obtaining the target quality inspection item, the smart device can call the corresponding operation script. Among them, the smart device can record the operation script of the automated detection device for different quality inspection items on the local device. Of course, in some further specific embodiments, the operation scripts of different quality inspection items can be pre-stored in the server. For the convenience of description, the server here is recorded as the second server.

[0028] The smart device may send the target quality inspection item to a second server, and the second server may store a data table of the relationship between the quality inspection items and the running scripts in advance.

[0029] After receiving the target quality inspection item, the second server can query the relationship data table between the quality inspection item and the running script. The running script corresponding to the target quality inspection item can be found by looking up the table. The second server feeds back the running script obtained by the query, so that the smart device obtains the running script. For the convenience of description, the running script is recorded as the target running script. This target running script is the script run by the current automated detection device.

[0030] Step 5: Send the target quantity, target identification number and target operation script to the automated detection device.

[0031] After obtaining the target operation script, the smart device can communicate with the automated detection device and send the target operation script to the automated detection device. In order to allow the automated detection device to know the number of printed circuit boards in the target batch to be detected, the smart device will also send the target number to the automated detection device.

[0032] Step 6: Send the target batch of printed circuit boards to be tested to the automated testing device in sequence.

[0033] After the intelligent device determines that the automated testing device has received the target quantity and the target running script, the intelligent device will control the transport device to sequentially deliver the target batch of printed circuit boards to be tested into the automated testing device through the transport device.

[0034] When the target batch of printed circuit boards to be tested is first fed into the automated testing device, the automated testing device will perform identity testing on the target marking plate. The automated testing device parses the marking symbol on the target marking plate to obtain the identity number recorded by the marking symbol. The identity number is compared with the target identity number. When the identity number is the same as the target identity number, the target running script is used as the running script for the current test to perform quality testing on the fed printed circuit board.

[0035] The automated detection device will detect the target batch of printed circuit boards in sequence. Since the automated detection device has received the target operation script, the automated detection device can perform targeted detection of the printed circuit boards by running the target operation script. Each time the automated detection device detects a printed circuit board, the count value of the automated detection device will increase by 1. The cumulative increase in the count value reflects the number of inspections of the current printed circuit board by the automated detection device. When the cumulative increase in the technical value of the automated detection device reaches the target number, the automated detection device will no longer use the target operation script for detection. In addition, the automated detection device will send a signal to the outside to prompt that the quality inspection of the current target batch of printed circuit boards to be inspected has been completed.

[0036] The present invention arranges printed circuit boards in order and sets marking symbols on the first board of the printed circuit boards, and determines the items that need to be quality inspected by the marking symbols. The printed circuit boards are sequentially fed into an automated inspection device, and the corresponding running scripts obtained by the automated inspection device are used to implement targeted quality inspection of the printed circuit boards, thereby improving the efficiency and intelligence of quality inspection.

[0037] Among them, the quality inspection items include: printed circuit inspection, electrical performance inspection, solder joint position inspection, and board insulation inspection.

[0038] For some printed circuit boards, such as single-layer printed circuit boards, it may be necessary to conduct: printed circuit testing, electrical performance testing. Of course, if the substrate of the printed circuit board is an aluminum substrate, it is also necessary to conduct board insulation testing. Of course, if the substrate of the single-layer printed circuit board is a glass fiber substrate, it is not necessary to conduct board insulation testing.

[0039] Of course, for a double-layer printed circuit board, it is necessary to carry out: printed circuit inspection, electrical performance inspection, and solder joint position inspection. Of course, if the substrate of the double-layer printed circuit board is an aluminum substrate, it is also necessary to carry out a board insulation inspection. Of course, if the substrate of the double-layer printed circuit board is a glass fiber substrate, it is not necessary to carry out a board insulation inspection.

[0040] As for the form of the marking symbol, in some further specific embodiments, the marking symbol may be in the form of a barcode. Of course, the marking symbol may also be in the form of a QR code.
