Abstract
Description
Technical Field
[0001] This utility model relates to the field of flying needle machine technology, specifically a flying needle machine capable of rapid needle tip calibration. Background Technology
[0002] As a highly efficient and precise circuit board testing device, the flying probe tester's core function is to drive tiny probes (i.e., "flying probes") to contact test points on the circuit board at extremely high speed and precision through a sophisticated mechanical structure and control system, thereby achieving comprehensive testing of the circuit board's electrical performance.
[0003] In practical applications, when a new needle needs to be replaced or the needle tip position deviates due to long-term use, needle tip calibration must be performed to ensure testing accuracy. Needle tip calibration is a crucial step. It compensates for positioning inaccuracies caused by factors such as needle tip wear, replacement, or mechanical errors by accurately measuring and calibrating the spatial position of the needle tip. Traditional needle tip calibration methods mostly rely on a dedicated calibration board. The calibration board is covered with test points at known locations. By testing contact with these points, the system can calculate the actual position of the needle tip and make corresponding adjustments. However, in the above-mentioned needle tip calibration methods, the operator needs to first remove the circuit board being tested from the test station, then replace it with a dedicated calibration board, and after calibration, remove the calibration board and replace it with the original circuit board to continue the previous testing process. This series of disassembly and assembly operations is not only cumbersome and complex, reducing overall testing efficiency, but also may increase the risk of circuit board damage.
[0004] Therefore, this invention proposes a flying needle machine capable of rapid needle tip calibration to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a flying needle machine capable of rapid needle tip calibration, thereby solving the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A flying probe machine capable of rapid needle tip calibration includes a body, the body including a test station for placing a circuit board for testing, and a calibration component for needle tip calibration is provided on the body, the calibration component being located next to the test station.
[0008] In one alternative: the calibration assembly includes a substrate and a calibration plate disposed on the substrate.
[0009] In one alternative: the calibration plate is a white film plate.
[0010] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows:
[0011] During tip calibration, the flying probe mechanism is controlled to move directly to the calibration component to perform tip calibration. There is no need to replace the circuit board being tested with the calibration board. After calibration, the circuit board can be tested directly. The operation is simple and convenient, which not only greatly improves the tip calibration efficiency and ensures the overall testing efficiency of the circuit board, but also avoids the risk of damage to the circuit board caused by disassembly and assembly operations.
[0012] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0018] Please see Figure 1 and Figure 2 A flying needle machine capable of rapid needle tip calibration includes a body 1, the body 1 including a test station 2 for placing a circuit board 3 for testing, and a calibration component 4 for needle tip calibration is provided on the body 1, the calibration component 4 being located beside the test station 2.
[0019] It should be noted that the machine body 1 also includes a base, frame, flying needle mechanism, drive mechanism, vision system and corresponding control system, etc., constituting a complete flying needle machine. All of the above are existing technologies and will not be described in detail here.
[0020] When replacing a new needle or when the needle tip position is inaccurate and calibration is required, the flying needle mechanism is controlled to move directly to the calibration component 4 for needle tip calibration. (First, the needle tip moves to the calibration point with preset known coordinates on the calibration component 4. Then, the needle tip slowly approaches the mark, and the contact signal is detected by the corresponding sensor to confirm the contact position. The system records the coordinates at this time and compares them with the theoretical coordinates to calculate the deviation value. Subsequently, the needle tip is finely adjusted according to the deviation value. The above process is repeated until the deviation is within the allowable range. Finally, the system saves the calibration data and completes the calibration.) There is no need to replace the circuit board 3 being tested with the calibration board. After calibration, the circuit board can be tested directly. The operation is simple and convenient, which greatly improves the efficiency of needle tip calibration, ensures the overall testing efficiency of the circuit board, and avoids the risk of damage to the circuit board caused by disassembly and assembly operations.
[0021] Please see Figure 2 In one embodiment of the present invention, the calibration component 4 includes a substrate 401 and a calibration plate 402 disposed on the substrate 401, wherein the calibration plate 402 is a white film plate.
[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
