[0002] The drilling trajectory instrument is a rapid non-destructive testing device for circuit boards. It is a key component used to inspect and verify each step of the circuit board manufacturing process to ensure that the final product meets the specifications and quality standards. It is necessary to test and inspect the performance and reliability of the circuit board.

[0003] Currently, our company produces several types of inclinometers and drilling trajectory analyzers. Due to their small internal structure, circuit board mounting, and limited space during testing, and because internal components rely on wires for external connections, incoming material inspection often requires soldering the wires before testing. However, if the circuit board is faulty, the wires must be removed from the circuit board with a soldering iron. This repeated soldering damages the solder pads, and because solder remains on the pads, suppliers sometimes find it difficult to replace parts, leading to buck-passing. Therefore, there is an urgent need to improve upon these existing problems.

[0004] Therefore, in view of the above-mentioned defects, the designer of this utility model, through dedicated research and design, and by integrating years of experience and achievements in related industries, has researched and designed a rapid non-destructive testing device for a drilling trajectory instrument circuit board to overcome the above-mentioned defects.

The middle part of the upper pressure plate is hinged to the vertical support portion. A spring is provided between the lower surface of one end of the upper pressure plate and the support plate. Four circular holes are equally spaced on the other end of the upper pressure plate. Four probes are fixed in the four circular holes. The probes are telescopic spring contact probes, so that the opening and closing of the upper pressure plate is realized by the spring provided between the upper pressure plate and the support plate. An aviation socket is provided on one side of the main housing. The probes are connected to the aviation socket through connecting wires.

[0008] The upper end of the upper pressure plate is also provided with a cable pressure plate to press and fix the connecting wire.

[0009] Wherein: the cable pressure plate is fixed to the upper surface of the upper pressure plate, and its lower surface is provided with a groove for the connecting wire to pass through and be positioned.

[0010] The lower part of the main housing is also provided with an upper cover, and the periphery of the upper cover is fixed to the periphery of the main housing.

[0011] Wherein: the support plate includes a rectangular plate body, the vertical support part extends upward from the middle of the plate body, the upper end of the vertical support part has a rotating hole, the middle of the upper pressure plate is provided with a long groove for the vertical support part to pass through, and the two sides of the long groove are provided with pin holes corresponding to the position of the rotating hole, so that the upper pressure plate can be hinged and fixed by passing the pin hole and the rotating hole through the pin.

[0033] See Figures 1 to 9 This invention demonstrates the rapid non-destructive testing device for the circuit board of the drilling trajectory instrument.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, the rapid non-destructive testing device for the drilling trajectory instrument circuit board includes at least a main housing 1, a support plate 3, an upper pressure plate 5, probes 6, and springs 7. The support plate 3 is fixedly mounted on the upper part of the main housing 1. A vertical support portion extends upward from the middle of the support plate 3. The middle part of the upper pressure plate 5 is hinged to the vertical support portion. A spring 7 is provided between the lower surface of one end of the upper pressure plate 5 and the support plate 3. Four Φ1.4 circular holes are equally spaced at 2.5mm intervals on the other end of the upper pressure plate. Four metal spring-type probes 6 are fixed in the four circular holes. Thus, the probes 6 pass through the upper pressure plate 5... A spring 7 is provided between the upper pressure plate 5 and the support plate 3 to achieve an opening and closing angle of 15° when the upper pressure plate 5 is pressed. An aviation socket 8 is provided on one side of the main housing 1. The probe 6 is connected to the aviation socket 8 through a connecting line 10. Thus, when testing is required, the upper pressure plate 5 is pressed, so that a space is created between the other end of the upper pressure plate 5 and the support plate 3 to place the circuit board to be tested. The pads of the circuit board to be tested are aligned with the probe. After the pressure plate 5 is released, the probe contacts the circuit board to be tested. At the same time, it is connected to a computer or other testing unit through the aviation socket to achieve rapid and non-destructive testing of the circuit board to be tested.

[0035] The upper end of the upper pressure plate 5 is also provided with a cable pressure plate 4 to achieve the pressing and fixing of the connecting wire.

[0036] The lower part of the main housing 1 is also provided with an upper cover 2, the periphery of the upper cover 2 is fixed to the periphery of the main housing 1 and forms an internal space for accommodating the connecting line 10.

[0037] See also Figure 4A , Figure 4B , Figure 5A and Figure 5B The diagrams show the structural schematics of the upper pressure plate 5 and the support plate 3 in this utility model. The support plate 3 includes a rectangular plate body. The vertical support part extends upward from the middle of the plate body. The upper end of the vertical support part has a rotating hole. The middle part of the upper pressure plate 5 is provided with a long groove for the vertical support part to pass through. The two sides of the long groove are provided with pin holes corresponding to the position of the rotating hole. Thus, the upper pressure plate 5 is hinged and fixed by passing the pin through the pin hole and the rotating hole.

[0038] Among them, such as Figure 6A and Figure 6B As shown, the cable pressure plate 4 is fixed to the upper surface of the upper pressure plate 5 by at least two screws / bolts, and its lower surface is provided with a groove for the connecting wire 10 to pass through and be positioned.

[0039] Among them, such as Figure 7A , Figure 7B , Figure 8A and Figure 8BAs shown, the main housing 1 is preferably a plastic housing with a length of 82.5 mm, a width of 57 mm, and a height of 21 mm. An opening is made on one side of the main housing 1 to install an aviation socket. The aviation socket is preferably a seven-pin Remer aviation socket. The periphery of the upper cover 2 is fixed to the lower surface of the main housing 1 by multiple screws / bolts.

[0040] Among them, such as Figure 9 As shown, the connection between the four probes and the aviation socket is illustrated via connecting wire 10.

[0041] Preferably, the probe is a telescopic spring contact probe, which has a built-in spring that can extend and retract when subjected to external force, and the outer shell of the telescopic spring contact probe is made of brass.

[0042] Preferably, the connecting wire 10 between the probe 6 and the aviation socket 8 is a four-color connecting ribbon cable, one end of which is soldered to the aviation socket 8, and the other end is connected to the probe 6 by a connecting plug 9.

[0043] Therefore, when testing the switch board, simply press down on the end of the upper pressure plate to deform the spring clip, lift the four probes, align the four pads of the switch board with the four probes of the testing device, and then release the upper pressure plate to fix the switch board.

[0044] The device of this invention can quickly detect whether the power board of a tracker is faulty. The testing method is as follows: insert the charging cable into the aviation socket of the testing device, and connect the charging board and the switch board through a flexible ribbon cable. This allows you to test the charging function of the charging board and the switch board to determine if they are normal. If the red LED on the power board lights up and there is a current value display on the charger, it means the power board is normal; if there is no current value or the red LED does not light up, it means the power board is faulty and needs to be replaced. The use of this device not only improves the testing speed but also ensures safety and reliability.

[0045] Among them, since drilling trackers rely on a Bluetooth module to connect the mobile phone and the probe when transmitting data, using this testing device allows for on-the-spot testing and immediate replacement without welding. It enables real-time connection with a Bluetooth-enabled mobile phone and is easy to operate. The testing method is as follows: Download the APP on the mobile phone, fix the Bluetooth switch board to the testing device, and connect the power board, Bluetooth board, and measuring board together with a flexible ribbon cable. Turn on the Bluetooth board switch and connect the probe through the APP. If the APP displays a successful Bluetooth connection, the Bluetooth board is normal. If the APP displays a Bluetooth connection failure, the Bluetooth module on the Bluetooth board is faulty and needs to be replaced.

[0046] Because the borehole trajectory instrument requires 485 communication during production for probe calibration, this function necessitates assembling and connecting all probe components to a computer via a USB-to-485 communication adapter. Using this testing device allows for simultaneous testing of the switch board, charging board, and Bluetooth module during the early stages of production, significantly shortening the production cycle. The testing method is as follows: Fix the switch and Bluetooth board to the testing device, and connect the power board, Bluetooth board, and measuring board using a flexible ribbon cable. Turn on the switch, insert the USB-to-485 communication cable from the computer into the aviation socket at the rear of the testing device, and click the calibration test software on the computer. If rotating the measuring board at different angles causes the measurement values ​​on the calibration software to fluctuate and display different angles, the measuring board is functioning normally. If the measurement value is zero or the response is too slow, the measuring board has a problem and needs to be replaced.

[0047] It is obvious that the above description and account are merely illustrative and not intended to limit the disclosure, application, or use of this utility model. Although embodiments have been described and illustrated in the accompanying drawings, this utility model does not limit the specific examples exemplified by the drawings and described in the embodiments as currently considered the best mode for implementing the teachings of this utility model.
