The present invention will be 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, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Example 1

FIG. 1 is a schematic flowchart of a method for testing a board card according to Embodiment 1 of the present invention. This embodiment is applicable to the situation of automatically testing a board card, and the method can be executed by a board card testing system.

As shown in Figure 1, the method specifically includes the following steps:

Step 110: Acquire the current image of the board to be tested by the image acquisition device, and determine the target category of the board to be tested according to the preset association relationship between the image of the board and the category of the board.

Wherein, the board testing system may include an image acquisition device, at least two groups of mating terminals and at least two test probes. The image acquisition device can collect environmental images within a preset range, and the plug-in terminal can be moved to connect with the connector at the end of the board to realize the communication between the board and external devices, thus completing the test of the board. The test probe can be a probe and can be moved to contact any point on the surface of the board to obtain fixed-point signals such as voltage and resistance at any point of the board. In this embodiment, there may be three sets of plug-in terminals and four test probes, each set of plug-in terminals includes two terminals, and different sets of plug-in terminals can be adapted to different types of boards.

The image acquisition device can acquire the environmental image in real time or periodically. After the environmental image is obtained, the board testing system can determine whether the board to be tested exists in the environmental image. If it does not exist, continue to acquire the environment image. If it exists, the current image of the board to be tested is obtained from the environment image, for example, the current image can be intercepted from the environment image, or the environment image can be used as the current image. The relationship between the board image and the board type is preset, and the board image is different for different types of boards. According to the current image, the board category corresponding to the current image can be found as the target category of the board to be tested.

In this embodiment, optionally, the board testing system further includes a transmission platform; correspondingly, before acquiring the current image of the board to be tested by the image acquisition device, it also includes: passing the first a sensor to judge whether the board to be tested is placed on the transmission platform; if so, start the transmission platform, and determine whether the board to be tested is transmitted to the recognition area through the second sensor installed on the preset recognition area; if so, then The transmission platform stops transmission and executes the acquisition of the current image of the board to be tested through the image acquisition device.

Specifically, the board test system may include a transmission platform, an image acquisition device, at least two sets of plug-in terminals, and at least two test probes. The transmission platform can be a conveyor belt and other devices. Users can place each board to be tested at the entrance of the transmission platform, and the transmission platform transmits the boards to be tested in turn to realize automatic testing of different boards to be tested. The entrance of the transmission platform is the starting end of feeding, and a first sensor is installed at the starting end of feeding, and the first sensor may be a photoelectric sensor. Through the first sensor, it can be determined whether there is a board to be tested at the beginning of the feeding. If there is, the transmission platform is controlled to start, and the board to be tested is transported to the end of the discharge, that is, the board to be tested is transported to the end of the conveyor belt. An identification area is set in advance, the identification area is on the transmission path, and a second sensor is installed at the identification area, and the second sensor may also be a photoelectric sensor. The second sensor can determine in real time whether there is a board to be tested in the recognition area, and when the board to be tested is transported to the recognition area by the transport platform, the second sensor recognizes the board to be tested. The system obtains the signal that the second sensor recognizes the board to be tested, controls the transmission platform to stop transmission, and the board to be tested stays in the recognition area.

An image capture device is also installed at the identification area, for example, the image capture device is installed above the identification area, and the image capture device may be a device such as a camera. The image acquisition device can acquire the image of the recognition area in real time, or the system can send a shooting instruction to the image acquisition device after the transmission platform stops transmission to acquire the image of the recognition area. If the image acquisition device acquires the environmental image in real time, after obtaining the environmental image, the board testing system can determine whether the board to be tested exists in the environmental image. If it does not exist, continue to acquire the environment image. If it exists, the current image of the board to be tested is identified from the environment image. If the image acquisition device starts after receiving the system shooting instruction, it can directly shoot the board to be tested. The beneficial effect of this setting is that the system can automatically determine whether to start the board test, the transmission platform automatically starts to work, and the user does not need to manually identify different boards, which reduces user operations, avoids board recognition errors, and improves board testing. Efficiency and Precision.

Step 120 , according to the target category, determine the target firmware program from the preset candidate firmware programs, and burn the target firmware program to the board under test through the test probe.

Wherein, after the target category of the board to be tested is determined, a firmware program corresponding to the target category can be searched from a plurality of preset candidate firmware programs as the target firmware program. When the board to be tested is placed on the transmission platform, there is no firmware program inside, and it cannot communicate and work with other devices, that is, it cannot be tested. Therefore, it is necessary to determine the target firmware program of the board to be tested, and to burn the target firmware program to the board to be tested, so as to run the program. The target firmware program can be programmed into the board to be tested through the test probe. The test probe can be in the form of a probe that contacts the preset position on the board to be tested to realize program programming. For example, the preset positions of the test probe and the board to be tested are a pair of pins and sockets, and the pins are inserted into the sockets for program programming, and the pins can be double-row pins.

In this embodiment, optionally, burning the target firmware program to the board card to be tested through the test probe includes: determining the target position on the board card to receive the target firmware program according to the target type; controlling the test probe to move to the target part, burn the target firmware program to the board under test through the burn-in terminal on the test probe.

Specifically, different types of boards under test have different locations for receiving target firmware programs. For example, the test probe can program programs from the center of the board or from the upper left corner of the board. Pre-store the part where different types of boards can receive the target firmware program. After the target type is determined, the target part of the corresponding type of the board to be tested can be found. The system can control the test probe to move to the target part of the board to be tested, contact the programming terminal on the test probe with the target part, and burn the target firmware program to the board to be tested through the programming terminal. The test probe can be located above the board to be tested, and the test probe can be controlled to move by the sliding shaft. In this implementation, there can be multiple test probes to ensure that the test probes can be moved to any part of the board to be tested, and each test probe can be installed with at least one programming terminal for programming the board firmware program. The beneficial effect of this setting is that the target firmware program can be automatically determined and programmed according to the board type, which effectively reduces user operations, prevents users from burning wrong programs, reduces the professional requirements for testers, and improves the efficiency of board testing. and accuracy, thereby improving the automation of board testing.

In this embodiment, optionally, after determining the target type of the board to be tested, the method further includes: according to the target type, determining a signal acquisition part on the board to be tested; controlling the test probe to move to the signal acquisition part to obtain the signal acquisition part Fixed point signal of the board.

Specifically, the test probe can also be used for signal acquisition at a preset fixed point on the board to be tested. Different types of boards have different preset fixed points for acquisition, and the preset fixed point is the signal acquisition part. The relationship between different types of boards and signal acquisition parts is pre-stored, and according to the target category of the board to be tested, the signal acquisition site for signal acquisition on the board to be tested can be determined. The board test system controls the test probe to move to the signal acquisition part, contacts with the signal acquisition part, and obtains the fixed point signal of the board to be tested. The fixed-point signal is the signal at the signal acquisition site, and the fixed-point signal can be a signal such as voltage and resistance. For example, the probe of the test probe contacts the chip on the board under test to obtain the internal voltage resistance at the position of the chip. In this embodiment, the fixed point signal may be acquired after the target firmware program is burned, or the target firmware program may be burned after the fixed point signal is acquired. The friendship effect of this setting is that the fixed point signal of the board to be tested can be automatically tested without manual hand-held signal testing equipment for testing, nor the need to manually determine the signal acquisition position on the board to be tested, which improves the test efficiency of the board. .

In this embodiment, optionally, after acquiring the fixed point signal of the board to be tested, the method further includes: determining the auxiliary test instrument of the board to be tested according to the target type; Transfer to an auxiliary test instrument to determine test results for fixed point signals.

Specifically, auxiliary test instruments associated with different types of boards are pre-stored. For example, the auxiliary test instruments may be devices such as an oscilloscope and a voltmeter. According to the target category of the board to be tested, determine the auxiliary test instrument for the board to be tested. After the fixed-point signal is acquired, the fixed-point signal is transmitted to the auxiliary test instrument, and the test result of the fixed-point signal is displayed by the auxiliary test instrument. For example, an instrument switching board may be provided in the board test system, and the instrument switching board may be used to connect the test probes to different auxiliary test instruments, so as to transfer the acquired fixed-point signals to the auxiliary test instruments. The instrument switching board can be a self-designed PCB (Printed Circuit Board, printed circuit board) board, with a switching module set inside. According to the board type and test type, the board test system controls the instrument switching board to switch the signal of the test probe to Auxiliary test instrumentation required to determine the value of the fixed point signal. The numerical requirements of the fixed-point signal can be preset in the system, and the actual measured fixed-point signal value is compared with the preset numerical requirements to determine whether the actual measured fixed-point signal value meets the preset numerical requirements, if so, Then it is determined that the test of the fixed-point signal passes, and if it is not satisfied, it is determined that the test of the fixed-point signal fails. The beneficial effect of this setting is that the internal voltage resistance and other signals of the board to be tested can be automatically tested, that is, not only the process of running the program on the board, but also whether the board is qualified for manufacture can be tested. If the internal voltage of the chip is 2V, the internal voltage of the chip can be obtained to realize a comprehensive automatic test of the board.

Step 130: Determine at least one group of target plug-in terminals according to the target type, control the target plug-in terminal to connect with the connector of the board to be tested, and obtain the signal to be tested of the board to be tested.

The board to be tested can generate the signal to be tested by running the target firmware program, and the board test system can obtain the signal to be tested to test the board. The mating terminals to be inserted into different types of boards can be different, and the mating terminals associated with different types of boards are pre-stored. According to the target category of the board to be tested, at least one group of corresponding target mating terminals is determined from all mating terminals. The board test system controls the target mating terminal to move to the connector of the board to be tested. For example, the movement of the mating terminal can be controlled by an electric lift table and a push rod cylinder. The connector is located at the tail of the board to be tested, and the target plug-in terminal can be plugged and connected to the connector, and the test signal of the board to be tested can be obtained through the target plug-in terminal. For example, the output voltage signal of the board to be tested can be obtained.

Step 140: Determine the target test case from the preset candidate test cases according to the target category, and determine the test result of the board to be tested according to the signal to be tested and the target test case.

Among them, multiple candidate test cases are stored in advance, and the association relationship between different types of boards and each test case is set. Determine the target test case from the candidate test cases according to the target category of the board to be tested. The target test case can specify the test environment of the board to be tested, for example, external devices that need to be connected to the board to be tested, or conditions such as voltage, temperature, and humidity required for the work of the board to be tested. Adjust the working environment of the board under test according to the target test case, for example, the test signal of the board under test can be transmitted to a preset external device. Determine whether the board to be tested is successfully tested according to the signal to be tested. For example, the target test case stipulates that the board to be tested needs to be connected to the signal light, and the condition for the successful test is that the signal light turns green. The signal to be tested is transmitted to the signal light, if the signal light is green, it is determined that the test of the board to be tested is successful; if the signal light is not green, it is determined that the test of the board to be tested has failed.

In this embodiment, optionally, determining the test result of the board to be tested according to the signal to be tested and the target test case includes: determining the auxiliary test equipment of the board to be tested according to the target test case; The signal to be tested of the board to be tested is transferred to the auxiliary test equipment for the auxiliary test equipment to generate operation data according to the signal to be tested; the operation data of the auxiliary test equipment is received, and the board to be tested is determined according to the preset test evaluation rules in the target test case Card test results.

Specifically, an external device that needs to be connected when the board is working can be specified in the test case as an auxiliary test device. According to the target test case, determine the auxiliary test equipment for the board under test, that is, the board under test cannot be tested alone, and the test board needs to communicate with the auxiliary test equipment before testing. After obtaining the signal to be tested of the board to be tested through the target pairing terminal, the signal to be tested is transferred to the auxiliary test equipment to realize the communication between the board to be tested and the auxiliary test equipment. Auxiliary test equipment works according to the signal to be tested and generates operating data. Receive the operation data of the auxiliary test equipment, and obtain the preset test evaluation rules from the target test case, and judge whether the operation data meets the requirements of the test evaluation rules. Make sure the board under test fails the test.

The signal to be tested of the board to be tested can be switched and transferred to the auxiliary test equipment through the preset signal conversion board. The signal conversion board can be a self-designed PCB board, with a switching module set inside, and the target to be tested is obtained through the target plug-in terminal. After the signal is received, the signal to be tested is uniformly switched from the signal conversion board to the external device or the corresponding signal point, so as to realize the complete execution of the workflow of the board to be tested. The beneficial effect of this setting is that the communication between the board to be tested and the external equipment is realized, a complete test environment is established, the whole process does not require manual participation, the automatic test is realized, and the test efficiency and accuracy of the board are improved.

After determining the test result of the board to be tested, the board testing system can send a restart instruction to the transmission platform, and the transmission platform starts to start. Continue to transfer the board to be tested from the identification area to the discharge end of the transfer platform to complete the testing process of the board to be tested. After the transfer of the board to be tested is completed, if there is a new board to be tested at the beginning of the feed, the transmission of the new board to be tested is continued. When the board to be tested stays in the identification area for testing, even if there is a new board to be tested at the beginning of the feed, it will not be transmitted, which realizes that multiple boards to be tested can be tested in sequence and improves the test efficiency.

In the technical solution of this embodiment, the current image of the board to be tested is acquired through an image acquisition device, and the target category of the board to be tested is determined. Burn the program to the board under test through the test probe, so that there is a target firmware program corresponding to the target category in the board under test, which is convenient for testing. Determine the target plug-in terminal corresponding to the target category, and connect the target plug-in terminal with the connector at the tail of the board to be tested to obtain the signal to be tested of the board to be tested and realize the communication between the board to be tested and the external device. Determine the target test case corresponding to the board to be tested, determine whether the board to be tested meets the requirements of the target test case according to the signal to be tested, and obtain the test result. The problem of manual identification and testing of boards in the prior art is solved, and the professional requirements for staff are reduced. According to the target category, carry out targeted automated testing of the board to be tested, reduce manual operations, and improve the testing efficiency and accuracy of the board.

If so, the transmission platform is started, the board to be tested is transferred to the identification area, and the second sensor installed on the preset identification area is used to determine whether the board to be tested is transferred to the identification area. If so, control the transmission platform to stop transmission. An image acquisition device is installed at the recognition area, and the current image of the board to be tested can be acquired through the image acquisition device. The relationship between different board images and board types is preset, and the target type of the board to be tested is determined according to the current image.

After the target category of the board to be tested is determined, the standard size corresponding to the board to be tested can be determined. Adjust the size of the board fixing platform according to the standard size of the board to be tested. The size of the board fixing platform can be represented by the width between the support rods. Consistent with the standard size of the board to be tested, the board to be tested can be fixed on the support rod. After adjusting the size of the board fixing platform, the gripper will place the board to be tested on the support rod and fix it, so that the upper and lower sides of the board to be tested are not blocked, which is convenient for testing the parts on the upper and lower sides.

If so, send a restart instruction to the transmission platform, the transmission platform starts transmission, and transfers the board to be tested to the discharge end of the transmission platform, and the test process of the board to be tested in the board test system ends. If there is a new board to be tested waiting for the test at the beginning of the feed, the transmission platform will continue to work and carry out a new round of testing. The beneficial effect of this setting is that, from the beginning of the feeding of the board to be tested into the transmission platform to the end of the discharge reaching the transmission platform, the whole process does not require manual participation, and is completed automatically by the board testing system.
