[0002] With the rapid development of automobiles, the number of scenarios in which circuit boards are used in automobiles is increasing. That is, automotive devices such as car computers, electric seats, or car refrigerators all need to be equipped with corresponding circuit boards, which also requires the circuit boards to be tested before they are assembled into automotive devices. In order to achieve efficient testing of circuit boards, existing test systems can use image recognition technology to pre-identify the assembly status of components on the circuit board and provide feedback to technicians through the display screen, so that technicians can determine whether the components on the circuit board are correctly installed before power-on testing. However, after confirming that the installation is correct, technicians are still required to manually check whether the circuit board can operate normally after power is turned on to confirm whether the circuit board is a qualified circuit board, which in turn affects the test efficiency.

[0039] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0040] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0041] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0042] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0043] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0044] <System Example>

[0045] Figure 1FIG. 1 is a schematic diagram of the structure of an automatic test system for producing automotive circuit boards according to an embodiment. Figure 1 As shown, the automatic testing system for automobile circuit board production may include an assembly testing device 1, a conveying device 3, a function testing device 2 and a controller (not shown in the figure).

[0046] The controller is electrically connected to the assembly detection device, the conveying device and the functional detection device respectively, and is configured to: determine the identification position of a first identification preset in the first sampling image in response to a first sampling image of the target circuit board fed back by the assembly detection device; wherein the identification position reflects the relative position of the target circuit board; determine the device assembly information of each functional partition of the target circuit board and the position area of each functional partition in the first sampling image according to the circuit board template and the identification position associated with the first identification; when the device assembly information meets the set assembly conditions, control the conveying device to move the target circuit board from the assembly detection position of the assembly detection device to the functional detection position of the functional detection device; when the target circuit board arrives at the functional detection position, control the detection interface in the functional detection device to be paired with the power interface of each functional partition according to the position area to perform a power-on test.

[0047] In this embodiment, the assembly inspection device may be configured with a camera or a laser radar to feed back a sample image to the controller, which can then identify various preset markers in the sample image, such as reflective markers, markers of specific colors, and the like.

[0048] In this embodiment, the assembly inspection device is equipped with a laser radar, for example. The laser radar can capture point cloud images. Specifically, when the conveyor device feeds the target circuit board into the assembly inspection device, the laser radar in the assembly inspection device can capture a first sample image of the target circuit board. The assembly inspection device can then feed the first sample image back to the controller, which can then identify the first marker in the first sample image and determine the marker's position.

[0049] In some examples, the circuit board template M1 corresponds to a first identifier, for example, Figure 1 As shown, the first markings are divided into markings A, B, C, and D. Marker A is a reflective marking with a size of 2×1, marking B is a reflective marking with a size of 1×1, marking C is a reflective marking with a size of 2×1, and marking D is a reflective marking with a size of 1×1. In other words, the first markings consisting of markings A, B, C, and D correspond to the circuit board template M1.

[0050] In some examples, such as Figure 1As shown, the positions of the first marker and the target circuit board are relatively fixed, the distance between the center point of marker A and the center point of marker B represents the length of the target circuit board, and the distance between the center point of marker A and the center point of marker C represents the width of the target circuit board, that is, the size of the target circuit board.

[0051] In this embodiment, the controller pre-stores a circuit board template associated with the target circuit board, for example, Figure 1 As shown, by attaching the identifiers A-ID D to the target circuit board according to the requirements of the circuit board template M1, the functional partitions of the target circuit board can be determined by the identifiers A-ID D, that is, the circuit board template M1 corresponding to the circuit board L1 has the identifier A in the upper left area corresponding to the power functional area, the identifier B in the upper right area corresponding to the main control functional area, the identifier C in the lower left area corresponding to the communication functional area, and the identifier D in the lower right area corresponding to the storage functional area. In other words, the device assembly information of each functional partition of the target circuit board and the position of the identifier associated with the first identifier can be determined.

[0052] In this embodiment, the set assembly conditions include, for example, that the components of each functional zone have been assembled onto the target circuit board, and that the components of each functional zone match the component models corresponding to the circuit board template. When the component assembly information meets these assembly conditions, the target circuit board can be moved from the assembly inspection position of the assembly inspection device to the functional inspection position of the functional inspection device by controlling the conveyor device.

[0053] In this embodiment, the controller may issue a movement instruction to the conveying device, so that the conveying device moves the target circuit board from the assembly inspection position of the assembly inspection device to the function inspection position of the function inspection device according to the set step.

[0054] In this embodiment, the detection interface in the functional detection device can be the power supply end of the power interface connected to the target circuit board. The controller can control the movement of the detection interface in the functional detection device according to the location area, and pair and electrically connect it with the power interface of each functional partition to perform power-on testing.

[0055] In other words, the first sampling image fed back by the assembly detection device is used to determine the relative position of the target circuit board and whether the device assembly information of the target circuit board meets the assembly conditions. When the assembly conditions are met, the conveying device is controlled to deliver the target circuit board to the functional detection device, and then paired with the power interface through the detection interface to perform a power-on test, thereby realizing the performance of the intelligent test circuit board and effectively improving the test efficiency.

[0056] In some embodiments, as Figure 1As shown, the target circuit board is configured with a specific number of positioning workpieces 20, each of which is affixed with a first reflective tape corresponding to a first mark (marker A to mark D). The conveying device 3 includes a conveyor belt 32, which is arranged between the assembly inspection device 1 and the functional inspection device 2. The conveyor belt 32 is provided with a limiting member that drives the positioning workpieces 20 to move along the conveying direction of the conveyor belt. The specific number is, for example, 2, 3, or 4. The limiting member is, for example, a limiting strip 31 arranged in an array on the conveyor belt.

[0057] The controller is further configured to: determine, in response to a first sampling image of the target circuit board fed back by the assembly detection device, a point cloud range in the first sampling image whose point cloud intensity exceeds a set threshold; and determine a point cloud position of the point cloud range in the first sampling image as the identification position of the first identification in the first sampling image.

[0058] In other words, by arranging the first reflective tape on the positioning workpiece, the recognition accuracy of the assembly detection device can be improved, and the positioning accuracy of the target circuit board can be effectively improved.

[0059] In some embodiments, there are multiple reflective stickers and different reflective stickers have different size values; the controller is also configured to: determine the number of point clouds in the point cloud range; determine the first identifier corresponding to the first size value reflected by the number of point clouds according to a preset mapping relationship; wherein the mapping relationship reflects that different size values correspond to different identifiers; determine the center position of the first identifier in the first sampling image as the identification position of the first identifier.

[0060] For example, Figure 1 As shown, the first marker is divided into marker A, marker B, marker C, and marker D. Marker A is a reflective marker with a size of 2×1, marker B is a reflective marker with a size of 1×1, marker C is a reflective marker with a size of 2×1, and marker D is a reflective marker with a size of 1×1. That is, there are multiple reflective stickers, and the different reflective stickers have different size values. Based on the different size values, the number of point clouds within the point cloud range of each reflective marker is also different. That is, the number of point clouds of marker A is greater than the number of point clouds of marker B. According to the preset mapping relationship, it can be determined that there are two 2×1 reflective markers and two 1×1 reflective markers on the target circuit board, and the two 2×1 reflective markers are located at both ends of one short side of the target circuit board, and the two 1×1 reflective markers are located at both ends of the other short side of the target circuit board.

[0061] In other words, by providing reflective tape, the recognition accuracy of the assembly detection device can be improved, thereby improving the accuracy of positioning the target circuit board.

[0062] In some embodiments, the system also includes a support plate that moves inside the functional detection device; the controller is also configured to: determine the target position area and interface access direction of the power interface corresponding to each functional partition in the position area based on the circuit board template; control the support plate to support the target circuit board in the direction opposite to the interface access direction, and then control the detection interface in the functional detection device to move to the corresponding target position area, and pair it with the power interface of each functional partition in the interface access direction to perform a power-on test.

[0063] In this embodiment, a six-axis robotic arm may be configured inside the function detection device, and the six-axis robotic arm can drive the support plate to move inside the function detection device.

[0064] In this embodiment, the circuit board template also sets the position of the power interface in the circuit board template and the interface access direction, for example, Figure 1 As shown, the target location area is Q1 area, and the interface access direction is from left to right. The controller can control the support plate to support the target circuit board from right to left, and then control the detection interface to connect with the power interface of Q1 area from left to right.

[0065] In other words, by providing a support plate, the efficiency of power interface pairing can be effectively improved.

[0066] In some embodiments, as Figure 1 As shown, an abutment strip 23 cooperating with the limit strip 31 is provided at the bottom of the positioning sleeve 20. After determining the target position area and the interface access direction of the power interface corresponding to each functional partition in the position area, the controller is further configured to: determine the first limit strip whose distance from the first identifier is less than the set distance through the first sampling image; determine the support direction of the first limit strip relative to the first identifier based on the positional relationship between the first limit strip and the first identifier. When the support direction is opposite to the interface access direction, the detection interface in the functional detection device is directly controlled to move to the corresponding target position area, and paired with the power interface of each functional partition in the interface access direction to perform a power-on test. For example, Figure 1 As shown, the support direction is from left to right, meaning that the limit bar 31 is the first limit bar supporting the target circuit board. At this point, the interface access direction is from right to left, eliminating the need to control the support plate; the connection between the test interface and the power interface can be directly controlled. In other words, because the first limit bar limits the target circuit board in the support direction, when the power interface is oriented in the same direction as the support, there's no need to control the support plate, effectively improving test efficiency.

[0067] In some embodiments, as Figure 2 As shown, the positioning workpiece includes a positioning sleeve 21 and a pressing member 22, and the pressing member 22 is provided on the positioning sleeve 21;

[0068] The pressing member 22 is used to apply pressure to fix the relative positions of the target circuit board and the positioning sleeve 21 .

[0069] In this embodiment, the clamping member 22 may include a bolt and a clamping plate. The bolt is threadedly connected to the positioning sleeve 21. One end of the bolt is used to fix to the clamping plate, and the other end of the bolt is used for the operator to rotate, so that the rotation of the bolt can drive the clamping plate to clamp the target circuit board.

[0070] In other words, by providing the pressing member, the stability between the positioning workpiece and the target circuit board can be effectively improved.

[0071] As used in the embodiments of the present disclosure, the controller memory is used to store a computer program that controls the controller processor to operate according to any of the embodiments of the automated testing method for automotive circuit board production. A skilled artisan can design a computer program based on the solutions of the embodiments of the present disclosure. How this computer program controls the processor's operation is well known in the art and will not be described in detail here.

[0082] Step S120 , determining the device assembly information of each functional partition of the target circuit board and the location area of each functional partition in the first sampling image according to the circuit board template and the marker position associated with the first marker.

[0083] Step S130 : When the device assembly information meets the set assembly conditions, the conveying device is controlled to move the target circuit board from the assembly inspection position of the assembly inspection device to the function inspection position of the function inspection device.

[0084] Step S140 , when the target circuit board arrives at the function detection position, the detection interface in the function detection device is controlled to pair with the power interface of each functional partition according to the position area to perform a power-on test.

[0085] In some embodiments, step S140 may include the following steps S1401 and S1402:

[0086] Step S1401 : determining target location areas and interface access directions of power interfaces corresponding to various functional zones in the location areas according to a circuit board template.

[0087] In step S1402, the support plate is controlled to support the target circuit board in the direction opposite to the interface access direction, and then the detection interface in the functional detection device is controlled to move to the corresponding target position area, and paired with the power interface of each functional partition in the interface access direction to perform a power-on test.
