[0004] In existing diagnostic and analysis work related to the hardware of smart water dispensers, the testing method involves performing functional verification operations on the completed circuit board according to different functional test items. When a fault is found during testing, the completed circuit board needs to be returned to the factory for repair. However, if it is returned to the factory for repair, the completed circuit board is a highly integrated facility with many integrated parts / components, resulting in a large workload and affecting the structural components of the finished product.

[0047] Example 1

[0048] As attached Figure 1As shown, the first aspect of this application provides a diagnostic analysis device based on the hardware of a smart water dispenser, used for diagnostic testing of the circuit board of the smart water dispenser after the IC device soldering work is completed, including:

[0049] Tooling box 1;

[0050] The test board support 4 is located on the surface of the tooling box and has at least one test slot for placing the test board.

[0051] Pressure plate 5 is provided on the surface of the tooling box and is used to install test pins;

[0052] Test pin 6 is located on the pressure plate and faces the test slot. It is used to detect the test data of the circuit board under test 7 and send it to the tooling control board.

[0053] The tooling control board 8 is located inside the tooling box and is used to process the test data and send it to the main control board after processing.

[0054] The main control board, located inside the tooling box, is used to analyze the test data through an embedded program;

[0055] The power supply is located inside the tooling box and is used for power supply;

[0056] The test pin is electrically connected to the tooling control board via a connecting wire;

[0057] The tooling control board and the power supply are electrically connected to the main control board, respectively.

[0058] In this solution, the test pin matches the empty space on the circuit board under test (PCB 7), allowing connection for testing. Under the control of the fixture control board 8, data acquisition and testing of PCB 7 are achieved. The main control board is primarily used for test diagnosis, performing data analysis and diagnosis through embedded programs, and reporting to the host computer. The host computer can also send test commands to the main control board, which parses the commands and forwards them to the fixture control board 8 and other components to achieve diagnostic operation control.

[0059] The tooling is a box structure, inside which the power supply and main board are isolated from the outside, and the main control board is wrapped in the motherboard compartment.

[0060] The test pin 6 and the circuit board under test 7 can move relative to each other. The test pin 6 can press down on the circuit board under test 7 to connect with it. Alternatively, the circuit board under test 7 can rise, contacting and connecting with the test pin 6. The specific pressing or rising action is achieved by a corresponding lifting assembly; this embodiment does not specify the method.

[0061] Lifting components, such as lifting levers, electric lifting rods, or hydraulic lifting rods, can be lifted and lowered under the control of the tooling control board 8 to complete the contact test between the test pin 6 and the circuit board under test 7.

[0062] The main application stage of this solution is after the soldering of IC devices on the circuit board is completed. At this time, the status verification and diagnosis of the IC devices on the circuit board are carried out.

[0063] As attached Figure 2 As shown, in this scheme, the test pin 6 presses down relative to the circuit board under test 7 and inserts into the mating hole of the circuit board under test 7. After mating with the circuit board under test 7 (hardware PCB board), diagnostic testing is performed, and the test data of the circuit board under test 7 is collected. The tooling control board 8 (logic control) collects and processes the data and then sends it to the main control board for specific diagnostic analysis. The main control board analyzes the test data through an embedded program and outputs it to the host computer.

[0064] Therefore, this solution enables rapid problem localization and related analysis. The testing process takes place after the soldering of IC components on the circuit board, at which point the status verification of the IC components on the circuit board is performed. Based on functions such as data remote transmission, automatic equipment positioning, water dispensing and billing, voice and display human-machine interaction, anomaly alarms, upgrade maintenance, and low-power operation in intelligent water dispensers, this solution simplifies the complex operations of production or repair personnel through integrated and convenient operation, making the operation more reliable and the operating environment more stable.

[0065] This solution can provide multiple test bays (three workstations can be tested simultaneously on the test board tray) for batch testing operations. It allows several devices to perform related hardware diagnostic analysis operations at the same time. At the same time, only the hardware main control board needs to be placed and positioned from the outside of the equipment before analysis operations can be carried out.

[0066] During testing, after soldering the IC components, the equipment is placed in the corresponding slot. The ejector pins and pressure plates ensure the reliability and stability of subsequent operations. If a problem arises, it is resolved according to production procedures; otherwise, it proceeds to the next step: complete testing of the integrated board. The operation is simplified.

[0067] Preferably, it further includes:

[0068] The motherboard compartment 9 is located inside the tooling box and is used to isolate the power supply and the main control board;

[0069] The main control board is located in the motherboard compartment.

[0070] The main control compartment also contains a motherboard compartment (main control board) and a medium-sized power supply (not shown in the picture), which ensures the environmental reliability of the motherboard compartment and also isolates the power supply from the motherboard.

[0071] Preferably, it further includes:

[0072] A support plate 10 is disposed on the upper surface of the tooling box for fixing and installing the pressure plate;

[0073] The pressure plate is parallel to the upper surface of the tooling box.

[0074] The pressure plate is parallel to the upper surface of the tooling box. In order to install the pressure plate, a support plate 10 is installed vertically.

[0075] Preferably, the test plate support is parallel to the upper surface of the tooling box; and the test plate support is provided with three test slots.

[0076] Preferably, the test pins include 25 pins, which simultaneously match and satisfy the diagnostic tests of the circuit boards under test on the three test slots.

[0077] This solution consists of 25 ejector pins * 3 test positions. The ejector pins are fixed at the upper pressure plate, and subsequent wiring connects to the tooling control board inside the tooling box. Stability and consistency are ensured by operating the lifting lever.

[0078] Preferably, it further includes:

[0079] L-shaped bracket 11 is fixed on the upper surface of the tooling box and is used to bundle the connecting wires between the test pin and the tooling control board.

[0080] The test pin 6 is vertically fixed on the pressure plate, and its tail is connected to the tooling control board 8 via a connecting wire. To avoid the wiring being messy, an L-shaped bracket 11 is used to bundle the connecting wires.

[0081] Preferably, it further includes:

[0082] Lifting assembly 12 is disposed on the upper surface of the tooling box and is used to lift the test plate support.

[0083] The lifting assembly is electrically connected to the tooling control board.

[0084] The lifting assembly 12 can be made of several electric telescopic cylinders or hydraulic rods arranged at the four corners. It can be electrically controlled and the lifting is controlled by the tooling control board to realize the relative movement and contact between the circuit board under test 7 and the test pin.

[0085] Therefore, this device is highly intelligent. Simply place the hardware object under test in the structural slot, and the transmission structure will remain stable. The host computer can then handle the testing process. If any abnormalities occur during testing, they can be observed and categorized through the host computer. Throughout the entire operation, testing time and difficulty are significantly reduced, while also simplifying the testing content and tools.

[0086] Example 2

[0087] Based on the description of Embodiment 1, a second aspect of this application provides a diagnostic analysis system based on intelligent water dispenser hardware, comprising:

[0088] A diagnostic analysis device based on intelligent water dispenser hardware;

[0089] The host computer is connected to the main control board of the device and is used to input control commands to the main control board or output diagnostic results generated by the main control board.

[0090] As attached Figure 1 and 3 The specific implementation process of this solution is shown below:

[0091] First, place the hardware PCB board of the device under test (currently for our company's water intake equipment, i.e., QS series products) on the "Test Board Support", and then align and press the PCB board under test downwards using the pins that are fixed in position above.

[0092] The device structure consists of 25 ejector pins and 3 test positions. The ejector pins are fixed to the upper pressure plate, and subsequent wiring connects to the tooling control board inside the tooling box. Stability and consistency are ensured by operating the lifting lever.

[0093] Below are the slots with corresponding structures to match the hardware PCB board, allowing workers to install them in one step with relatively stable positioning. Subsequently, the ejector pins will align with the corresponding positions on the object being tested, thus connecting the data lines.

[0094] The tooling box is a fixed structure for the main control board. External data is introduced through connecting cables and analyzed and processed on the main control board. Finally, the results are input and output through a host computer, achieving fully automated intelligent detection throughout the entire process.

[0095] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
