Description

Technical Field

[0001] This utility model relates to the field of foreign object detection technology, and more specifically, to an automatic detection device for foreign object collision noise. Background Technology

[0002] The product carries the risk of introducing various particles during its welding, assembly, and other processes. If not detected in time, these particles will form foreign matter within the enclosed product. Under conditions of extremely high acceleration or severe impact, these foreign particles will be activated and released, moving randomly and erratically within the chamber, either suspending within the cavity or falling onto certain contact parts, posing a significant threat to the product's reliability. This can range from minor issues like short circuits, pipe blockages, and jamming of moving parts to more serious consequences such as explosions and severe quality accidents. Current technology relies primarily on manual shaking of components and judgment based on experience and sound, which suffers from high subjectivity, high false negative rates, and low efficiency. While automated collision noise detection equipment based on vibration excitation has emerged in recent years, existing technologies still suffer from poor clamping compatibility. Fixed clamps struggle to adapt to different sizes and shapes of tested parts (such as irregularly shaped circuit boards and multi-cavity housings), especially when dealing with irregularly shaped parts.

[0025] Example

[0026] Please refer to Figures 1-4 This embodiment provides an automatic detection device for foreign object collision noise, including a clamping assembly, a vibration assembly, and an identification assembly. The vibration assembly includes a vibration platform 1. The clamping assembly includes at least one clamping member and two positioning plates 2 arranged parallel and symmetrically on the vibration platform 1. A loading area for placing the object to be tested is formed between the two positioning plates 2. The clamping member includes a cylinder 3, a connecting member 9, and a clamping part 10. The cylinder 3 is disposed on the vibration platform 1, and the connecting member 9 connects the telescopic end of the cylinder 3 to the clamping part 10. The clamping part 10 can move above the loading area and clamp the object to be tested within the loading area. The identification assembly faces the loading area and is used to monitor the sound information emitted by the object to be tested.

[0027] The clamping assembly is used to fix the object to be tested onto the vibration platform 1. Specifically, after the cylinder 3 moves, it drives the connecting member 9 to move, thereby causing the clamping part 10 to move above the object to be tested, so that the clamping part 10 cooperates with the positioning plate 2 to clamp the object to be tested. When dealing with irregular objects to be tested, it can be directly clamped with the positioning plate 2, clamping the object to be tested in the vertical direction. After clamping, the vibration platform 1 can be started, so that the identification component can monitor the sound information emitted by the object to be tested, and draw a conclusion on foreign object detection based on the sound information. Therefore, this automatic foreign object collision noise detection device can efficiently and quickly complete the fixation of the object to be tested, especially for irregular objects.

[0028] It is worth noting that, in order to further accommodate test pieces of different sizes, the position of the positioning plate 2 on the vibration platform 1 in this embodiment is adjustable. Specifically, the vibration platform 1 has two parallel sliding grooves (not shown in the figure), and sliders (not shown in the figure) are connected to both ends of the positioning plate 2, with the two sliders slidingly disposed within the sliding grooves. In this way, the two positioning plates 2 can be adjusted laterally, thereby adjusting the distance between the two positioning plates 2.

[0029] Please refer to Figures 1-3In this embodiment, a lateral moving module 11 and a longitudinal moving module 12 are provided between the cylinder 3 and the vibration platform 1. The lateral moving module 11 is disposed on the vibration platform 1. The longitudinal moving module 12 is disposed at the moving end of the lateral moving module 11, and the cylinder 3 is disposed at the moving end of the longitudinal moving module 12. Specifically, the clamping assembly includes four clamping members, and the clamping portions 10 of the four clamping members are respectively located at the four corners of the workpiece being tested. Adjacent clamping members are grouped together, and the clamping members in the same group are all disposed at the moving end of the longitudinal moving module 12. In this way, the position of each group of clamping members can be adjusted according to needs, and the user can determine the clamping position according to the specific shape of the workpiece being tested, which can further improve the clamping stability. It should be noted that the lateral moving module 11 and the longitudinal moving module 12 are both prior art, and can be referred to as a linear slide module. The aforementioned lateral movement module 11 and longitudinal movement module 12 are actually used to adjust the position of the clamping part 10 on the corresponding clamping member on the x-axis and y-axis of the spatial coordinates, while the aforementioned cylinder 3 is used to adjust the position on the z-axis of the spatial coordinates. In this way, the clamping part 10 can be effectively adjusted to any position that needs to be clamped on the above-mentioned workpiece in three-dimensional space, so as to adapt to workpieces with different regular shapes, and further improve the stability of clamping and fixing the workpiece.

[0030] Please refer to Figures 1-3 In some embodiments of this example, the connecting member 9 has an L-shaped structure, and its two ends are respectively connected to the pressing part 10 and the telescopic end of the cylinder 3. The L-shaped structure of the connecting member 9 allows the lateral telescopic movement of the cylinder 3 to be converted into the lifting and lowering of the pressing part 10.

[0031] Please refer to Figure 1 and Figure 2 Furthermore, in this embodiment, the positioning plate 2 is provided with a plurality of positioning holes 13 evenly spaced apart, and at least one positioning block 15 is provided on the positioning plate 2. The positioning block 15 can be fixed to any of the positioning holes 13 by means of bolts, and the positioning block 15 can abut against the side wall of the test piece. In order to better clamp and fix the test piece, the positioning block 15 is provided on the positioning holes 13 to constrain the movement of the test piece in the horizontal plane, which can further enhance the clamping and fixing stability. The positioning holes 13 are arranged in an array, and the positioning block 15 is provided with a waist hole 16. The positioning block 15 can be fixed at a specific position on the positioning plate 2 by means of bolts passing through the waist hole 16 and the positioning hole 13 in sequence. The user can fix the positioning block 15 at an appropriate position to limit the test piece according to the needs, which can effectively constrain the test piece.

[0032] Please refer to Figure 4In some embodiments of this example, the identification component includes a vibration data sensor and at least one sound sensor. The vibration data sensor is disposed on the vibration platform 1, and the sound sensors are disposed in the loading area, capable of collecting sound information emitted by the object under test within the loading area during vibration. The vibration data sensor is actually an accelerometer disposed within the vibration platform 1, primarily used to collect data such as vibration frequency and amplitude. The sound sensor is used to detect sound wave information. This embodiment employs multiple sound sensors, which are disposed in pre-defined areas on the object under test.

[0033] Please refer to Figure 4 Furthermore, in this embodiment, both the vibration data sensor and the sound sensor are connected to the same control unit, which is connected to a display screen. The information detected by both the sound sensor and the vibration data sensor is transmitted to the control unit, which processes the received information into stress elastic wave information and sound wave information. These two waves propagate in the tested component, forming a reverberation signal, which is defined as a displacement signal. Once the displacement signal is acquired, it is amplified by a preamplifier, received and processed by the control unit, and displayed on the display screen. The testing personnel can determine the nature of the signal based on the displayed waveform and thus draw a testing conclusion.

[0034] It should be noted that the sound sensor in this embodiment uses a particle acoustic sensor as the sensing terminal. Before testing, the test piece is divided into grid coordinates to determine different areas. Then, multiple particle acoustic sensors are numbered and arranged in the corresponding areas. Finally, a professional particle acoustic coupling agent is used for coupling.

[0035] Please refer to Figure 3 In some embodiments of this utility model, the vibration platform 1 is provided with a soundproof outer shell 17. The soundproof outer shell 17 can prevent external sound from interfering with the detection.

[0036] Please refer to Figure 4 In this embodiment, each inspected item has a number, which carries information about the inspected item. The control unit is connected to a barcode scanner, which scans the number and transmits this information to the control unit, forming unique identification information that is then stored.

[0037] During use, the part to be tested is placed in the loading area, and the part is in contact with the two positioning plates 2. A manual barcode scanner reads the product number, which is transmitted to the control unit for confirmation. Simultaneously, the control unit generates a storage unit with this barcode information according to a preset program for later storage of the test report for the part. Before scanning, the horizontal movement module 11 and the vertical movement module 12 adjust the position of each clamping part 10 above the part to ensure effective clamping after contact. At the same time, sound sensors are installed on the part in their respective areas. Simultaneously, the cylinder 3 is activated, causing it to press the clamping part 10 against the surface of the part. The vibration platform 1 is activated, and a start signal is sent to the control unit. The control unit will then activate the vibration data sensor and sound sensor according to a preset delay (customizable). After activation, the vibration data sensor and sound sensor collect relevant data. The control unit processes the detected information into stress elastic wave information and sound wave information. Two waves propagate in the tested component, forming a reverberant signal, which is defined as a displacement signal. Once the displacement signal is acquired, it is amplified by a preamplifier, received and processed by the control unit, and displayed on a screen. The testing personnel can determine the signal nature based on the displayed waveform and thus draw a test conclusion. After information acquisition is complete, the vibration platform 1 is shut down and operation stops. The control cylinder 3 returns to its initial position, and the entire test process ends.

[0038] It should be noted that the aforementioned control unit is an integrated circuit chip. It is a small but complete microcomputer system that integrates a central processing unit (CPU) with data processing capabilities, random access memory (RAM), read-only memory (ROM), multiple I / O ports and interrupt system, timer / counter and other functions (and may also include display driver circuit, pulse width modulation circuit, analog multiplexer, A / D converter and other circuits) onto a single silicon chip using very large-scale integrated circuit technology. It is widely used in the field of industrial control.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
