Description

Technical Field

[0001] This utility model relates to electronic water pump controller testing technology, specifically to a portable ICT testing device based on Bluetooth communication. Background Technology

[0002] In the field of automotive electronic water pumps, functional and performance testing of the electronic water pump controller is a crucial step in ensuring product quality. Currently, the industry commonly uses ICT (In-Circuit Testing) to test circuit boards. Traditional ICT testing solutions require automated production lines. The technical process involves using probes to contact test points on the circuit board under test, collecting voltage signals from electronic components such as open circuits, short circuits, resistors, capacitors, diodes, and transistors. These signals are then uploaded to a host computer, which integrates and analyzes the data. Finally, the product's qualification is determined by manual judgment or by setting a threshold range.

[0003] However, existing technologies have significant limitations:

[0004] On the one hand, the testing process relies on fixed stands, special tooling, control modules and host computer equipment, resulting in high system investment costs and complex structure;

[0005] On the other hand, the manual operation involves many steps, requiring professional personnel to monitor the data from the host computer and make judgments, which not only increases the workload but also reduces the efficiency of testing. In addition, traditional solutions are limited by the layout of desktop equipment and cannot meet the portability requirements of scenarios such as on-site maintenance and rapid spot checks.

[0006] To address the aforementioned issues, this invention proposes a handheld inspection device based on wireless communication. This device transmits detection signals wirelessly to an external device, which can be either a host computer or a mobile app, thereby simplifying the testing process and reducing equipment costs. Utility Model Content

[0007] The purpose of this invention is to provide a simple handheld water pump circuit board ICT inspection device that separates the inspection terminal from the automated production line and transmits the inspection signal wirelessly, thereby simplifying the testing process and reducing equipment costs.

[0008] To achieve the above objectives, the present invention provides a simple handheld water pump circuit board ICT inspection device, which includes a housing, a battery, a wireless transmission module, and a detection circuit board inside the housing. The detection circuit board is connected to multiple probes, which are used to contact the test points of the circuit board under test for detection. The multiple probes are arranged in an array.

[0009] A switch is located on the side wall of the housing, protruding from the side wall; the battery is connected to the detection circuit board and the wireless transmission module via the switch.

[0010] The housing is equipped with an upper cover, which is used to seal the probe during storage to prevent dust and moisture.

[0011] The upper surface of the housing is recessed downwards and has an annular slot. The lower end of the upper cover is inserted into the annular slot and fits the upper cover.

[0012] The upper cover has an upward handle, and the side wall of the housing has a downward handle.

[0013] This utility model has the following advantages:

[0014] This invention features a simple structure, small size, and is easy to carry and handhold. Multiple probes are arranged in an array, allowing the circuit board under test to be placed on each probe and stably supported by them during testing. By turning on the switch and placing the circuit board on the probes, each probe contacts the corresponding test point on the circuit board. The test signal is transmitted wirelessly to an external device, which can be a large host computer or a mobile app. The large host computer is no longer necessary, simplifying the testing process and reducing equipment costs. This invention is particularly suitable for on-site repair and rapid sampling inspection scenarios.

[0015] When not in use, the top cover can be closed to seal the probes, thus preventing dust and moisture. When in use, the top cover should be opened.

[0016] The lower end of the upper cover is inserted into a ring slot, which improves the assembly stability between the upper cover and the shell during the storage of this utility model, and also makes it less likely for dust and external moisture to enter the upper cover.

[0050] like Figure 1 As shown, the simple handheld water pump circuit board ICT inspection device of this utility model includes a housing 1, a battery 3, a wireless transmission module 4 and a detection circuit board 10 are provided inside the housing 1. The detection circuit board 10 is connected to multiple probes 2 (metal probes) at the top. The probes 2 are used to contact the test points of the circuit board under test for detection. The multiple probes 2 are arranged in an array.

[0051] A switch 9 is provided on the side wall of the housing 1, and the switch 9 protrudes from the side wall of the housing 1; the battery 3 is connected to the detection circuit board 10 and the wireless transmission module 4 through the switch.

[0052] This invention features a simple structure, small size, and convenient portability and handheld operation. Multiple probes 2 are arranged in an array, allowing the circuit board under test to be placed on each probe 2 and stably supported by them during testing. Turning on switch 9 places the circuit board under test on each probe 2, making each probe 2 contact the corresponding test point on the circuit board. The test signal is transmitted wirelessly to an external device via the wireless transmission module 4. This external device can be a host computer or a mobile app, simplifying the testing process and reducing equipment costs. This invention is particularly suitable for on-site repair and rapid sampling inspection scenarios. The wireless transmission module 4 preferably uses a WIFI module or a Bluetooth module. The test circuit board 10 can be any existing ICT online testing equipment, or other circuit boards matching the testing task can be used, with a built-in A / D conversion module.

[0053] The housing 1 is covered with an upper cover 5, which is used to seal the probes 2 during storage to prevent dust and moisture. When not in use, the upper cover 5 is closed to seal the probes 2, thus preventing dust and moisture. When in use, the upper cover 5 is opened.

[0054] The upper surface of the housing 1 is recessed downwards and has an annular slot 7. The lower end of the upper cover 5 is inserted into the annular slot 7 and is adapted to fit the upper cover 5. The insertion of the lower end of the upper cover 5 into the annular slot 7 improves the assembly stability between the upper cover 5 and the housing 1 during the storage of this utility model, and also makes it less likely for dust and external moisture to enter the upper cover 5.

[0055] The upper cover 5 is provided with an upper handle 6, and the side wall of the housing 1 is provided with a lower handle 8. The upper handle 6 and the lower handle facilitate the movement or fine adjustment of the position of this utility model.

[0056] The working process of this utility model is as follows:

[0057] I. Preparation Stage

[0058] Equipment inspection: Remove the upper cover 5 on the housing 1 (removed via the upper handle 6) to expose the array of probes 2, and ensure that the probes 2 are free from bending, oxidation or other damage; check whether the lower handle 8 on the side wall of the housing 1 is secure and whether the battery 3 has sufficient power.

[0059] Environmental adaptation: Place the device on a flat table (no fixed stand required), and fine-tune its position using the lower handle 8 to ensure that the circuit board under test can be placed stably above the probe 2 array.

[0060] II. Testing Operation Procedure

[0061] Start-up device: Press the protruding switch 9 on the side wall of the housing 1, the battery 3 supplies power to the detection circuit board 10 and the wireless transmission module 4, and the device enters the working state.

[0062] Circuit board positioning: The circuit board of the water pump controller under test (i.e. the circuit board under test) is placed on the array of probes 2. The distribution design of the array probes 2 ensures that the test points of the circuit board make precise contact with the probes 2, while the probes 2 provide stable support for the circuit board.

[0063] Signal acquisition and transmission:

[0064] The test circuit board 10 acquires the voltage signal (such as open circuit, short circuit, component parameters, etc.) of the circuit board under test through the probe 2 and converts it into a digital signal;

[0065] The wireless transmission module 4 (such as a Bluetooth module) transmits digital signals to external devices (mobile APP or host computer) in real time.

[0066] Data processing and results feedback:

[0067] After receiving data, external devices such as mobile apps compare it with a built-in preset threshold database (such as the standard range of component parameters and the threshold for determining open / short circuits).

[0068] If the data exceeds the threshold, an external device such as a mobile app will indicate the location and type of the fault; if the data is normal, it will display "qualified" and automatically record the test results (such as time and circuit board number).

[0069] III. Termination and Storage

[0070] Shutdown: After the test is completed, press switch 9 to turn off the power and remove the circuit board under test.

[0071] Dust protection: Align the lower end of the upper cover 5 with the annular slot 7 on the surface of the housing 1, insert it vertically and fasten it. The slot structure enhances the sealing and prevents dust and moisture from entering the probe 2 area.

[0072] Portable and mobile: The device can be carried to the next test point or storage location via the upper handle 6 or the lower handle 8 to complete the entire testing process.

[0073] The role of critical design in the work process is as follows:

[0074] Array probe 2: Simultaneously achieves signal acquisition and circuit board support, without the need for additional fixing fixtures;

[0075] Wireless transmission module 4: Free from the constraints of cables, supports stable communication within 10 meters, and is suitable for various scenarios such as production lines and after-sales service;

[0076] Upper cover 5 and annular slot 7: form physical protection when not in use, extending the service life of probe 2;

[0077] Through the above process, the device achieves a testing mode of "ready to use, handheld and portable, and wirelessly connected". Compared with traditional ICT testing, it reduces the reliance on host computers and manual intervention, has higher testing efficiency, and simplifies the testing process and reduces equipment costs.
