[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0037] It should also be noted that, unless otherwise specified, the term "connection" herein may refer not only to a direct connection but also to an indirect connection involving an intermediate.

[0038] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0039] Figure 1 This is a schematic diagram of the structure of the DPU board conduction test system provided by an embodiment of the present application. Figure 1 As shown, the system at least includes: a conduction test jig 110 , a scanning terminal 120 and a test terminal 130 .

[0040] The continuity test jig 110 is a tool for testing the electrical connectivity of a DPU board, and is typically used to ensure the correctness and reliability of connections between various circuits and components on the DPU board during production and maintenance.

[0041] like Figure 2As shown, the conduction test jig 110 includes a jig carrier 1110. The jig carrier 1110 is used to place the DPU board to be tested. A board label is set at a designated position of the DPU board to be tested, and the board label is used to uniquely indicate the DPU board to be tested, so as to track and record the test results of each DPU board to be tested. In other words, the board labels set on different DPU boards to be tested contain different board information, and each board label contains unique board information. Among them, the board label includes but is not limited to a serial number, a barcode or a QR code. The DPU board to be tested is set with the side with the board label facing up, and the position of setting the board label is fixed on the DPU board to be tested.

[0042] In some embodiments of the present invention, the board information is read by scanning with a scanning terminal 120 fixed on the continuity test jig 110 .

[0043] The scanning terminal 120 is a device used to scan and identify card labels. Different card labels use different scanning terminals 120. For example, if the card label is a QR code, the scanning terminal 120 may be a QR code scanner; if the card label is a barcode, the scanning terminal 120 may be a barcode scanner.

[0044] The board information refers to the information obtained after the scanning terminal 120 scans the board label, including the DPU board serial number, model, version information, production date, manufacturer information or configuration parameters.

[0045] In some embodiments of the present invention, the scanning terminal 120 is fixed on the conductivity test jig 110, and the scanning window or scanner of the scanning terminal 120 is aligned with the jig carrier 1110 to ensure that during each conductivity test, the scanning terminal 120 can accurately scan the board label on the DPU board to be tested, read the board information, and send the read board information to the test terminal 130.

[0046] Specifically, the scanning terminal 120 is used to scan the board label to obtain the board information corresponding to the DPU board to be tested, and send the board information to the test terminal 130 .

[0047] In some embodiments of the present invention, a wired or wireless communication connection is established between the scanning terminal 120 and the test terminal 130. For example, the scanning terminal 120 is connected to the test terminal 130 via a USB data cable, or the scanning terminal 120 is connected to the test terminal 130 via a Bluetooth module. After scanning and obtaining the board information, the scanning terminal 120 sends the board information to the test terminal 130 based on the communication connection between the scanning terminal 120 and the test terminal 130.

[0048] In some embodiments of the present invention, Figure 2As shown, after the scanning terminal 120 is connected to the test terminal 130 via a data cable, it must be calibrated before it begins scanning the board labels on the DPU under test. The connection interface is opened on the test terminal 130, and in response to the connection control in the connection interface, the test terminal 130 begins to establish a connection with the scanning terminal 120. After the connection is successful, the board label position sampling begins. The sampling range only covers the board label position, with an error range of -0.2mm to +0.2mm in both directions. This serves as the reference point for the scanning terminal 120's automatic scanning.

[0049] Specifically, the test terminal 130 is also used to: receive a scanning terminal connection instruction before scanning the board card label, and establish a connection with the scanning terminal 120 in response to the received scanning terminal connection instruction; generate a scanning terminal calibration instruction when the connection with the scanning terminal 120 is successful; and send the scanning terminal calibration instruction to the scanning terminal 120.

[0050] The scanning terminal 120 is also used to: upon receiving a scanning terminal calibration instruction, scan the current board label corresponding to the current DPU board placed on the jig carrier 1110 to determine the position information of the current board label; and determine the reference point of the scan based on the position information.

[0051] like Figure 1 As shown, the test terminal 130 is connected to the scanning terminal 120 and the continuity test jig 110. After receiving the board information sent by the scanning terminal 120, the test terminal 130 identifies the board information and confirms whether the DPU board to be tested has passed the continuity test through the board information.

[0052] Specifically, the test terminal 130 is used to identify the board information when receiving it and obtain an identification result; if the identification result indicates that the DPU board to be tested has not been subjected to a continuity test, control the continuity test jig 110 to perform a continuity test on the DPU board to be tested.

[0053] In some embodiments of the present invention, identifying the board information includes confirming whether the board information currently scanned is information in the preset board information, and confirming whether the board information currently scanned is information of a DPU board that has completed a continuity test.

[0054] The preset board information refers to the board information pre-stored in the test terminal 130. By comparing the scanned board information with the preset board information, the identity and authenticity of the DPU board to be tested can be verified, ensuring that the DPU board to be tested meets the expected specifications and standards. Automatically comparing board information improves the efficiency of identifying and recording board information, avoids human input errors, and improves work efficiency. By comparing the scanned board information with the information of previously tested boards, repeated testing of DPU boards that have already passed the continuity test can be avoided, ensuring an efficient, orderly, and reliable production and testing process.

[0055] Specifically, identifying the board information and obtaining an identification result includes: comparing the board information with preset board information to obtain a comparison result; when the comparison result indicates that the preset board information includes the board information, comparing the board information with the tested board information to obtain an identification result.

[0056] If the comparison result indicates that the preset board information does not include the board information, the test terminal 130 is further configured to output a first prompt message. The first prompt message is configured to notify the user that the current DPU board to be tested does not meet the expected specifications and standards, and to prompt the user to replace the DPU board to be tested.

[0057] If the identification result indicates that the DPU board to be tested has completed the continuity test, the test terminal 130 is further configured to output a second prompt message, wherein the second prompt is configured to inform the user that the current DPU board to be tested is undergoing a repeated test and to prompt the user to replace the DPU board to be tested.

[0058] In this case, the test terminal 130 also includes an information output component. The first and second prompt information may be implemented in ways that include, but are not limited to, text and / or audio. The information output components corresponding to different prompt information are described below.

[0059] The first case: the first prompt information and the second prompt information include prompt text. In this case, the information output component includes a display component for displaying text, such as a display screen.

[0060] The second scenario: the first prompt information and the second prompt information include prompt audio. Accordingly, the information output component includes an audio output component for playing the prompt audio.

[0061] In other embodiments, the prompt information may also include text prompt instructions and / or audio prompt instructions. In this case, the prompt information is used to instruct other devices to play and display prompt text and / or play prompt audio. The information output component also includes a communication component.

[0062] Accordingly, outputting the first prompt information includes: sending the first prompt information to other devices via the communication component. Outputting the second prompt information includes: sending the second prompt information to other devices via the communication component. This embodiment does not limit the implementation of the prompt information and the information output component.

[0063] Controlling the continuity test jig 110 to perform a continuity test on the DPU board to be tested includes: generating a continuity test signal; and sending the continuity test signal to the continuity test jig 110 .

[0064] Correspondingly, the continuity test jig 110 is further used to perform a continuity test on the DPU board to be tested when a continuity test signal is received.

[0065] like Figure 2 As shown, in some embodiments of the present invention, the continuity test jig 110 further includes a control unit 1120 , a solenoid valve 1130 , a cylinder 1140 , a pressing module 1150 , a positioning column 1160 and a probe 1170 .

[0066] Among them, the control unit 1120 is used to receive the conduction test signal; the solenoid valve 1130 is installed on the air supply pipe of the cylinder 1140, and is used to control the movement of the cylinder 1140; the piston rod of the cylinder 1140 is connected to the pressing module 1150, and is used to drive the movement of the pressing module 1150; the positioning column 1160 is used to indicate the pressing distance of the pressing module 1150 and fix the position of the DPU board to be tested; the probe 1170 is arranged under the jig carrier 1110, and is used to contact the test point on the DPU board to be tested when the pressing module 1150 is pressed down to the position of the positioning column 1160.

[0067] Specifically, the control unit 1120 is used to control the solenoid valve 1130 to open when receiving a conduction test signal, so that the cylinder 1140 drives the pressing module 1150 to press down to the positioning column position, thereby fixing the DPU board to be tested on the fixture carrier 1110; when the probe 1170 contacts the test point on the DPU board to be tested, the conduction test of the DPU board to be tested is performed.

[0068] After performing the conduction test on the DPU board to be tested, the control unit 1120 is further used to: after the conduction test, control the pressing module 1150 to lift up to the initial pressing position; generate a test completion instruction, and send it to the test terminal 130.

[0069] Accordingly, the test terminal 130 is further configured to: upon receiving a test completion instruction, add the board information to the information of boards that have passed the test; and output a test completion prompt. The test completion prompt is used to inform the user that the continuity test of the current DPU board to be tested has been completed and to prompt the user to replace the DPU board to be tested.

[0070] In addition, if Figure 2 As shown, the continuity test tool 110 further includes a test abort control and a tool start control.

[0071] The test abort control is used to stop the continuity test jig 110, and the jig start control is used to start the continuity test jig 110. Accordingly, the continuity test jig 110 is further configured to generate a test abort instruction based on the abort operation applied to the test abort control, thereby triggering the execution of an operation to abort the continuity test of the DPU board under test.

[0072] In some embodiments of the present invention, the test abort control and the jig start control are physical buttons or virtual buttons displayed on a touch screen. This embodiment does not limit the implementation of the test abort control and the jig start control.

[0073] In addition, the scanning terminal 120 is provided with a scanning start control.

[0074] like Figure 2 As shown, the scanning terminal 120 is connected to the scanning start control via two IO lines and to a 24V power module via three IO lines (one positive, one negative, and one ground). The scanning start control is used to trigger the scanning action, and the power module is used to power the scanning terminal 120.

[0075] Correspondingly, the scanning terminal 120 is also used to: generate a scan start instruction based on the start operation acting on the scan start control to trigger the execution of the scanning board card label, obtain the board card information corresponding to the DPU board card to be tested, and send the board card information to the test terminal 130.

[0076] In some embodiments of the present invention, the scan start control is a physical button or a virtual button displayed on a touch screen. This embodiment does not limit the implementation method of the scan start control.

[0077] In summary, the DPU board continuity test system provided in this embodiment places the DPU board to be tested on the jig carrier of the continuity test jig, scans the board label of the DPU board to be tested by the scanning terminal, obtains the board information corresponding to the DPU board to be tested, and sends the board information to the test terminal; the board label is used to uniquely indicate the DPU board to be tested; the test terminal is connected to the scanning terminal and the continuity test jig, and is used to identify the board information when receiving the board information to obtain an identification result; when the identification result indicates that the DPU board to be tested has not yet been subjected to the continuity test, the continuity test jig is controlled to place the DPU board to be tested on the DPU board to be tested. The board is tested for conductivity; it can solve the problem of manual scanning of the DPU board to be tested, which is prone to missed scans, wrong scans, etc., resulting in low DPU board test efficiency; the DPU board to be tested is placed on the jig carrier, and the scanning terminal is used to automatically scan the board label to avoid missed scans and wrong scans that may occur in manual scanning, which can reduce test hours and save test costs, thereby improving the DPU board test efficiency; at the same time, by identifying the board information of the DPU board to be tested, the possibility of missed scans and wrong scans can be further reduced, and repeated scanning of the DPU board can be avoided, thereby further improving the DPU board test efficiency.

[0078] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
