[0015] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0016] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0017] The embodiments of the present application provide a printed circuit board testing device and equipment.

[0018] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0019] Please refer to Figure 1 , Figure 1 A schematic block diagram of a printed circuit board testing device provided in one embodiment of the present application.

[0020] like Figure 1 As shown, the printed circuit board testing device provided in an embodiment of the present application includes: a jig control module 10, the jig control module 10 includes a jig carrying component 101 and a fixing component 102, the jig carrying component 101 is provided with at least one test position, the test position is used to place a printed circuit board to be tested, and the fixing component 102 is connected to the jig carrying component 101; the fixing component 102 has a switchable first state and a second state, and when the fixing component 102 is in the first state, it can cooperate with the jig carrying component 101 to fix the printed circuit board placed in the test position, and when the fixing component 102 is in the second state, the printed circuit board placed in the test position can be removed from the test position;

[0021] The detection module 20 includes a communication detection component 201 and a display component 202. The communication detection component 201 is in a first state and is communicatively connected to the printed circuit board placed in the test position and is used to perform a communication test on the printed circuit board placed in the test position. The display component 202 is used to obtain and display the test results of the communication detection component 201.

[0022] The power supply module 30 is connected to the fixture control module 10 and the detection module 20 and is used to supply power to the fixture control module 10, the detection module 20 and the printed circuit board.

[0023] Exemplarily, the test station is removably mounted on the fixture support component 101. During use, the test station can be replaced based on the product being tested, making the printed circuit board testing apparatus suitable for printed circuit boards of various shapes and functions. The fixing component 102 can cooperate with the fixture support component 101 to secure or release the printed circuit board in the test station. Specifically, when the fixing component 102 is in a first state, it secures the printed circuit board in the test station, and when in a second state, it releases the printed circuit board in the test station.

[0024] For example, by fixing the printed circuit board in the test position of the fixture support component 101, the detection module 20 is connected to the printed circuit board, for example, the communication detection component 201 in the detection module 20 is connected to the printed circuit board, so that the detection module 20 can test the printed circuit board. The display component 202 can be an LED display screen for displaying whether the printed circuit board has passed the test on the LED display screen, but is of course not limited to this and is not limited here.

[0025] Exemplarily, the power supply module 30 is used to convert and stabilize the incoming mains electricity, supply power to the fixture control module 10 , the detection module 20 and the printed circuit board, and provide overvoltage protection and short-circuit protection.

[0026] Please refer to Figure 2 , Figure 2 A schematic block diagram of a printed circuit board testing device provided in another embodiment of the present application.

[0027] like Figure 2 As shown, in some embodiments, the detection module 20 further includes:

[0028] a hardware detection component 203, which is connected to the printed circuit board placed in the test position in a first state and is used to perform a hardware test on the printed circuit board;

[0029] The electrical parameter detection component 204 is connected to the printed circuit board placed in the test position in the first state, and is used to obtain current parameters and voltage parameters of the printed circuit board to perform electrical parameter testing on the printed circuit board.

[0030] For example, during the process of testing a printed circuit board, it is also necessary to test whether the hardware of the printed circuit board is functioning properly and whether the operating voltage and current are within normal ranges. Therefore, the hardware testing component 203 is connected to the printed circuit board to perform a hardware test on the printed circuit board, and the electrical parameter testing component 204 obtains the current and voltage parameters of the printed circuit board to determine whether the current and voltage parameters are within normal ranges.

[0031] The determination of whether the hardware and electrical parameters of the printed circuit board have passed the test may be implemented by a processor. The processor may be, for example, an STM32F407, but is certainly not limited thereto and is not limited here.

[0032] Please refer to Figure 3 , Figure 3 A circuit diagram of an electrical parameter detection component provided in one embodiment of the present application.

[0033] like Figure 3 As shown, HLW8012 obtains the current parameters and current parameters of the printed circuit board through the V1P and V2P pins, and connects to the processor U1. The processor U1 judges the current parameters and current parameters of the printed circuit board to determine whether the printed circuit board passes the electrical parameter test.

[0034] In some embodiments, the hardware detection component 203 includes an LED detection module, which is connected to the LED lamp beads of the printed circuit board in the first state to perform hardware testing on the LED lamp beads of the printed circuit board.

[0035] For example, the printed circuit board testing device provided in the embodiment of the present application is used to test AR glasses at the PCBA stage. LED lamp beads are important components in AR glasses. Therefore, it is necessary to test the working condition of the LED lamp beads through the LED detection module.

[0036] In some embodiments, the LED detection module further includes a brightness detection component, which is used to obtain the brightness of the LED lamp beads during the hardware testing process and perform hardware testing on the LED lamp beads of the printed circuit board based on the brightness of the lamp beads.

[0037] For example, in addition to testing whether the LEDs can be lit, to ensure that the AR glasses produced can function properly later, it is also necessary to confirm that the brightness of the LEDs on the printed circuit board meets the requirements. Therefore, after counting the LEDs, it is necessary to use the brightness detection component to obtain the brightness of the LEDs, and use the processor to compare the brightness of the LEDs with the preset brightness to confirm that the brightness of the LEDs is within the range that can ensure the normal operation of the AR glasses.

[0038] In some embodiments, the fixture control module 10 includes a pneumatic control system, which is connected to the fixed component 102. When the pneumatic control system takes in air, it drives the fixed component 102 to switch to the first state, and when the pneumatic control system exhausts air, it drives the fixed component 102 to switch to the second state.

[0039] For example, the fixing member 102 can be driven to switch between the first and second states by a pneumatic control system. Specifically, the pneumatic control system can be, for example, a pneumatic cylinder. When the fixing member 102 is in the first state, the cylinder is in a downward pressure state; when the fixing member 102 is in the second state, the cylinder is in a raised state.

[0040] For example, the cylinder can be controlled by a relay connected to the power module.

[0041] In some embodiments, a test probe is provided on the test position of the fixture carrying component 101 , and the test probe abuts against a test point on the printed circuit board when the fixing component 102 is in the first state.

[0042] For example, test points are pre-set on the printed circuit board. The positions and numbers of the test points on different types of circuit boards are different. Therefore, it is necessary to use the test points that are suitable for the printed circuit board to be tested for testing.

[0043] In some embodiments, the communication detection component 201 is used to establish a Bluetooth connection with the printed circuit board and obtain the burned version number of the printed circuit board through the Bluetooth connection to determine whether the printed circuit board passes the communication test based on the burned version number.

[0044] For example, the communication detection component 201 can test the communication function of the printed circuit board to determine whether the communication module on the printed circuit board is functioning properly. It can also obtain the printed circuit board's programming version number during the communication function test. If the programming version number cannot be obtained or is incorrect, the printed circuit board communication test is determined to have failed. The communication detection component 201 can communicate with the printed circuit board via Bluetooth, or other wired or wireless means, which are not limited herein.

[0045] In some embodiments, the power supply module 30 is used to divide the input voltage, convert the input voltage into an output voltage, and respectively power the fixture control module 10 , the detection module, and the printed circuit board.

[0046] Please refer to Figure 4 , Figure 4 A circuit diagram of a power supply module provided in one embodiment of the present application.

[0047] like Figure 4 As shown, in some embodiments, the power module 30 further includes a relay module, which is used to obtain the output current of the power module 30 and supply power to the printed circuit board according to the received control instructions.

[0048] Exemplarily, the power supply module 30 is used to divide the input voltage so that the magnitude of the input voltage is adapted to the voltage required by the printed circuit board testing device. Specifically, a DC power supply is connected through the DC power socket DC1, and then the higher input voltage is converted into a lower stable output voltage through MP2315GJ-Z. For example, the 12V input voltage is converted into a 5V output voltage to power the various modules and printed circuit boards of the printed circuit board testing device.

[0049] For example, the power supply to the printed circuit board from the power module is controlled by a relay. When the printed circuit board is fixed in the test position, the relay needs to be started to achieve electrical connection between the power module and the printed circuit board, thereby providing protection for the printed circuit board and preventing the printed circuit board from burning out during the test.

[0050] The present application also provides a printed circuit board testing device, which includes a memory, a controller, and the printed circuit board testing apparatus as described in any one of the embodiments of the present application.

[0051] The printed circuit board testing device and equipment provided in the embodiments of the present application integrate various functions for the printed circuit board stage testing of AR glasses, thereby reducing the size and complexity of the printed circuit board testing device.
