Description

Technical Field

[0001] This application relates to the field of PIND detection, in particular to a sensor support structure and a composite sensor for a PIND detection device. Background Art

[0002] Particle Impact Noise Detection (PIND) is a system for detecting the reliability of components, and is commonly used to detect loose particles of foreign matter inside the packages of electronic components such as integrated circuits, transistors, capacitors, and relays in the aerospace / military field.

[0003] Its principle is to use a vibration table to generate a series of specified mechanical shocks and vibrations. Through the shock, the particles (i.e., foreign matter) trapped in the component are loosened, and then through vibrations at a certain frequency, the foreign matter is displaced within the system. The process of the moving foreign matter displacing within the component is a random combination of the sliding process and the impact process of the foreign matter relative to the component housing.

[0004] During this process, stress elastic waves and acoustic waves will be generated. The two waves propagate in the component housing and form a reverberation signal, which is defined as the displacement signal. After the displacement signal is picked up by using acoustic sensing technology, it is pre-amplified, collected, and processed for display.

[0005] The greater the intensity of the shock and vibration test conditions, the easier it is to activate the foreign matter particles. Under the current industry detection conditions, a detection system generally has only one vibration center, which can meet the existing state of a single detection point. In more cases, the same detection system often corresponds to multiple detection points. For example, with the increasing demand for accuracy, multiple monitoring points at different parts of the same detection object are required; or with the increasing demand for efficiency, when multiple detection elements are detected simultaneously, multiple monitoring points also need to operate simultaneously.

[0006] In this case, due to the different distances between each detection point and the vibration center, the actual shock accelerations at different detection points will be different. The detection points farther away from the vibration center often have the problem of dull perception of vibration shock. Therefore, there will be a large vibration shock deviation between the detection points farther away from the vibration center and the vibration center detection point. Summary of the Invention

[0007] The purpose of this application is to provide a sensor support structure and a composite sensor for a PIND detection device that improve the consistency of shock acceleration.

[0008] To solve the above problems, the present application provides a sensor support structure for a PIND detection device, including a tabletop, where the tabletop is provided with a plurality of fixing positions for fixing sensitive elements; the tabletop is connected with reinforcing ribs for improving the consistency of the impact acceleration of each area of the tabletop.

[0009] Through the strengthening of the reinforcing ribs, the impact acceleration deviation between each fixing position of the tabletop under the vibration state is reduced, making it closer to the impact acceleration of the vibration center detection point. When it is necessary to detect different parts of the same detection element simultaneously or detect multiple elements simultaneously, the detection accuracy is improved.

[0010] In some embodiments, the tabletop is circular; the fixing positions include more than three first fixing positions, and the first fixing positions are annularly distributed; reinforcing ribs are provided between adjacent first fixing positions.

[0011] The annularly distributed first fixing positions are equidistant from the vibration center, and reinforcing ribs are arranged between adjacent first fixing positions, which can minimize the impact acceleration deviation between each first fixing position.

[0012] In some embodiments, it further includes a column; the top of the column is connected to the tabletop at the center of the tabletop; the tabletop includes a first tabletop and a second tabletop, the second tabletop faces the column, and its diameter is smaller than that of the first tabletop; the first fixing positions are arranged on the second tabletop.

[0013] This design, while taking into account the accommodation positions of the detection element and the sensitive element, reduces the weight of the sensor support structure by reducing the area of the sensitive element accommodation position - that is, the second tabletop, thereby improving the bearing capacity and working effectiveness of the sensor.

[0014] In some embodiments, the fixing positions further include second fixing positions, and the second fixing positions are arranged at the center of the bottom of the second tabletop.

[0015] Arranging the second fixing positions at the center increases the number of detectable points of the composite sensor. At the same time, on the premise of the reinforcing rib design, the deviation of the impact acceleration between the second fixing position and the first fixing position is well alleviated.

[0016] In some embodiments, the fixing positions are groove-shaped; the column is hollow, and the groove formed by the second fixing position is communicated with the hollow part inside the column.

[0017] The hollow structure of the column and the groove structure of the fixing positions can both effectively reduce the weight of the composite sensor and optimize the PIND detection process.

[0018] In some embodiments, the number of the first fixing positions is 4, and they are arranged in a cross shape with respect to the center of the tabletop.

[0019] For a circular tabletop, the arrangement of four mutually symmetric first fixing positions makes the tabletop more stable during vibration.

[0020] In some embodiments, the reinforcing rib includes a first reinforcing rib, and the first reinforcing rib is connected between the first tabletop and the second tabletop.

[0021] The part where the first tabletop extends beyond the second tabletop is located at the edge of the tabletop, which is also the part most likely to generate impact acceleration deviation. Arranging the first reinforcing rib here can effectively reduce the impact acceleration deviation of the edge part.

[0022] In some embodiments, the first reinforcing rib is connected to the outer edge of the first tabletop, strengthening the outer edge of the first tabletop where the impact acceleration deviation is the largest.

[0023] In some embodiments, the first reinforcing rib and the second tabletop form a first connecting arc surface in the circumferential direction, and the arc-shaped connection makes the whole more stable under vibration and impact conditions.

[0024] In some embodiments, the reinforcing rib includes a second reinforcing rib, and the second reinforcing rib is connected between the second tabletop and the column body.

[0025] The second reinforcing rib makes the overall strength of the reinforcing rib greater, and the synthetic sensor as a whole is also more stable.

[0026] In some embodiments, a boss is provided at the bottom of the column body, and the second reinforcing rib is connected to the outer edge of the boss, making the connection of the second reinforcing rib more stable.

[0027] In some embodiments, the second reinforcing rib and the column body form a second connecting arc surface in the circumferential direction, and the arc-shaped connection makes the whole more stable under vibration and impact conditions.

[0028] In some embodiments, the first reinforcing rib and the second reinforcing rib are located in the same plane and are integrally formed, improving the integrity of the reinforcing rib.

[0029] In some embodiments, the sensor support structure for the PIND detection device is an integral part, and the overall structure has better stability. The tabletop is 100 mm, which is the conventional tabletop diameter for multiple monitoring points in this field.

[0030] In some embodiments, the thickness of the reinforcing rib is 3 - 4 mm. This thickness is the optimal thickness range after comprehensively considering various influencing factors.

[0031] To solve the above problems, the present application also provides a synthetic sensor, including the above-mentioned sensor support structure for the PIND detection device and a plurality of sound-sensitive elements, and the sound-sensitive elements are fixed to the fixing positions.

[0032] The synthetic sensor of the present application improves the sensor support structure through PIND detection equipment, reducing the impact acceleration deviation between multiple detection points when multiple sound-sensitive elements detect simultaneously. This makes the impact acceleration at each detection point closer to the impact acceleration at the vibration center, improving the stability and reliability of the entire PIND detection equipment and meeting the actual requirements of the detection site.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0040] In a first aspect, to solve the problem of large impact acceleration deviation between multiple detection points in current PIND detection, the present application provides a sensor support structure for a PIND detection device, as Figures 1 - 3 shown.

[0041] The sensor support structure for the PIND detection device of the present application includes a tabletop 10. The tabletop 10 is provided with a plurality of fixing positions 20 for fixing sensitive elements. The tabletop 10 is connected with reinforcing ribs 30, and the reinforcing ribs 30 are used to improve the consistency of the impact acceleration of each area of the tabletop 10.

[0042] Common sensitive elements for PIND detection devices can be sound-sensitive elements, pressure-sensitive elements, etc. The corresponding area of each sensitive element is where the detection element is placed to collect the sound pressure generated by the detection element. During detection, each detection element generates impact acceleration through the vibration of the tabletop. The reinforcing ribs 30 can be connected to the bottom surface, upper end or side of the tabletop 10, and their arrangement is based on not affecting the arrangement of the detection element and the sensitive element and enhancing the stability of the tabletop 10.

[0043] Through the strengthening of the reinforcing ribs 30, the deviation of the corresponding impact acceleration of each fixing position 20 of the tabletop 10 in the vibrating state is reduced. When it is necessary to detect different parts of the same detection object simultaneously or detect multiple elements simultaneously, the detection accuracy is improved.

[0044] Optionally, the tabletop 10 is circular; the fixing positions 20 include more than three first fixing positions 21, and the first fixing positions 21 are annularly distributed. Reinforcing ribs 30 are provided between adjacent first fixing positions 21.

[0045] Of course, the tabletop 10 can be in various shapes such as square, regular polygon, etc., mainly for facilitating the placement of the detection elements and ensuring that the detection elements do not interfere with each other.

[0046] The number of the first fixing positions 21 can also be 2, symmetrically distributed on the tabletop 10.

[0047] The reinforcing ribs 30 can also be arranged in other positions, preferably without interfering with the arrangement of the sensitive elements and the detection elements.

[0048] The tabletop 10 is preferably circular. Currently, most detection devices have a single vibration center. By setting the vibration center at the center of the circle of the tabletop 10, the vibration deviation of each area of the tabletop 10 can be reduced. The first fixing positions 21 are preferably more than three and are annularly distributed. In this case, the first fixing positions 21 are equidistant from the vibration center, which can minimize the deviation of the impact acceleration between the first fixing positions 21. Reinforcing ribs 30 are provided between adjacent first fixing positions 21, which can also reduce the difference between the first fixing positions 21 and leave a convenient arrangement position for the sensitive elements and the detection elements.

[0049] Optionally, a sensor support structure for a PIND detection device of the present application further includes a column body 40. The top end of the column body 40 is connected to the table top 10 at the center of the table top 10. The table top 10 includes a first table top 11 and a second table top 12. The second table top 12 faces the column body 40, and its diameter is smaller than that of the first table top 11. The first fixing position 21 is provided on the second table top 12.

[0050] The column body 40 facilitates the setting of the acceleration sensitive element 60 of the composite sensor and is connected to the vibration table below. Therefore, it is also possible to set one or more other structures on the table top 10 to meet this function, such as setting multiple column bodies on the table top 10 to form a bracket form, or the table top 10 respectively forming a connection part of the acceleration sensitive element and a connection part of the vibration table, etc.

[0051] On the other hand, since the volume of the detection element is larger than that of the sensitive element, with this design, while ensuring the accommodation positions of the detection element and the sensitive element, by reducing the accommodation position of the sensitive element - that is, the area of the second table top 12, the weight of the sensor support structure is reduced, thereby improving the working effectiveness of the sensor. Therefore, the setting of the second table top 12 can also be cancelled.

[0052] Optionally, the fixing position 20 further includes a second fixing position 22, and the second fixing position 22 is provided at the center of the bottom of the second table top 12.

[0053] Arranging the second fixing position 22 at the center increases the number of points that the composite sensor can detect. At the same time, the second fixing position 22 at the center is closest to the impact acceleration at the vibration center and will not affect the impact acceleration of the first fixing position 21. It is the most cost-effective arrangement method of the fixing position 20.

[0054] Optionally, the fixing position 20 is in a groove shape; the column body 40 is a hollow structure, and the groove formed by the second fixing position 22 is communicated with the hollow part inside the column body 40.

[0055] The hollow column body 40 structure not only facilitates the setting of the sensitive element in the second fixing position 22, but also facilitates the setting of the acceleration sensitive element 60 at the bottom of the column body 40. In addition, the groove structure of the fixing position 20 and the hollow structure of the column body 40 can both effectively reduce the weight of the composite sensor. An increase in the weight of the composite sensor leads to a greater thrust requirement for the vibration table, thus requiring an increase in current to increase the thrust; however, after running for a period of time, due to the increase in current, the generated heat becomes larger, and as the heat increases, the resistance becomes larger, which in turn leads to a decrease in current and a gradual decrease in the thrust of the vibration table. Therefore, reducing the weight of the sensor support structure for the PIND detection device can optimize the PIND detection process.

[0056] Optionally, there are 4 first fixing positions 21, which are arranged in a cross shape with respect to the center of the tabletop 10. The symmetrical arrangement of the 4 first fixing positions makes the tabletop more stable during vibration. At the same time, it meets the optimal arrangement plan for the diameter of the tabletop 10 of 100 mm for current multi-point measurement. If the number is more, the detection elements cannot be placed on the tabletop; if the number is less, the detection efficiency is reduced.

[0057] Optionally, the reinforcing rib 30 includes a first reinforcing rib 31. The first reinforcing rib 31 is connected between the first tabletop 11 and the second tabletop 12.

[0058] Of course, the first reinforcing rib 31 can also be separately provided on the first tabletop 11 or the second tabletop 12.

[0059] The part where the first tabletop 11 exceeds the second tabletop 12 is located at the edge of the tabletop 10, which is also the part most likely to form an impact acceleration deviation. Arranging the first reinforcing rib 31 here can effectively reduce the impact acceleration deviation of the edge part.

[0060] Optionally, the first reinforcing rib 31 is connected to the outer edge of the first tabletop 11.

[0061] Of course, the first reinforcing rib 31 can also be connected to the lower part, or the side, or surround the side of the first tabletop 11.

[0062] The first reinforcing rib 31 is connected to the outer edge of the first tabletop 11, strengthening the outer edge of the first tabletop 11 where the impact acceleration deviation is the largest. And preferably, the first reinforcing rib 31 is joined to the bottom edge of the first tabletop 11, achieving a two-way balance between the strength of the reinforcing rib 30 and the quality of the integrated sensor.

[0063] Optionally, a first connecting arc surface 33 is formed between the first reinforcing rib 31 and the circumferential direction of the second tabletop 12.

[0064] The arc-shaped connection makes the transition smooth when the first reinforcing rib 31 is connected to the second tabletop 12. The overall vibration and impact received by the integrated sensor are more stable, and it is also more convenient for the integrated molding of the sensor support structure of the PIND detection device.

[0065] Optionally, the reinforcing rib 30 includes a second reinforcing rib 32, and the second reinforcing rib 32 is connected between the second tabletop 12 and the column body 40.

[0066] The second reinforcing rib 32 makes the overall strength of the reinforcing rib 30 greater, and the integrated sensor is also more stable. At the same time, the column body 40 is arranged at the vibration center, connecting the reinforcing rib 30 to the vibration center and extending the range of the vibration stable center.

[0067] Optionally, a boss 41 is provided at the bottom of the column body 40, and the second reinforcing rib 32 is connected to the outer edge of the boss 41.

[0068] The diameter of the cylindrical part 40 of the boss 41 becomes larger, and it is more stable when connected to the vibration table. The second reinforcing rib 32 is connected here, which not only effectively meets the strengthening effect of the reinforcing rib 30, but also does not increase the weight of the sensor support structure due to excessive strengthening.

[0069] Optionally, the second reinforcing rib 32 and the column 40 form a second connecting arc surface 34 in the circumferential direction.

[0070] The second connecting arc surface 34 makes the connection between the second reinforcing rib 32 and the column 40 smooth, and the vibration and impact received by the synthetic sensor as a whole are more stable, and it is also more convenient for the PIND detection equipment to integrally form the sensor support structure.

[0071] Optionally, the first reinforcing rib 31 and the second reinforcing rib 32 are located in the same plane and are integral parts.

[0072] Here, the first reinforcing rib 31 and the second reinforcing rib 32 can be separately arranged and connected at the second table surface 12, or the first reinforcing rib 31 and the second reinforcing rib 32 can be arranged together, that is, the reinforcing rib 30 is directly connected to the first table surface 11 and the boss 41 - in this case, part of the reinforcing rib 30 is connected to the second table surface 12.

[0073] Of course, the first reinforcing rib 31 and the second reinforcing rib 32 can also be in different planes respectively.

[0074] The setting of the first reinforcing rib 31 and the second reinforcing rib 32 as integral parts improves the integrity of the reinforcing rib 30.

[0075] Optionally, the sensor support structure for the PIND detection equipment is an integral part.

[0076] The sensor support structure is integrally formed, and the overall structure stability is better, and the weight of the connecting parts during the connection of parts is also reduced.

[0077] Optionally, the table surface 10 is 100 mm. The table surface 10 can also be other sizes, and 100 mm is the conventional table surface diameter for multiple monitoring points in this field.

[0078] Optionally, the thickness of the reinforcing rib 30 is 3 - 4 mm. Preferably, the thickness of the reinforcing rib 30 is 3 mm. The determination of the thickness of the reinforcing rib depends on various elements such as the size of the table surface 10, the sizes of other parts of the sensor support structure, and the number of detection points.

[0079] In a second aspect, an embodiment of the present application provides a synthetic sensor, including the aforementioned sensor support structure for the PIND detection equipment, and a plurality of sound - sensitive elements, and each sound - sensitive element is fixed at a different fixed position of the sensor support structure.

[0086] Among them, the reinforcing ribs 30 include a first reinforcing rib 31 and a second reinforcing rib. The first reinforcing rib 31 and the second reinforcing rib 32 are in the same plane and are an integral part.

[0087] The first reinforcing rib 31 is connected between the first tabletop 11 and the second tabletop 12 and is connected to the outer edge of the first tabletop 11. The first reinforcing rib 31 and the second tabletop 12 form a first connecting arc surface 33 in the circumferential direction.

[0088] The second reinforcing rib 32 is connected between the second tabletop 12 and the column 40. A boss 41 is provided at the bottom of the column 40, and the second reinforcing rib 32 is connected to the outer edge of the boss 41. The second reinforcing rib 32 and the column 40 form a second connecting arc surface 34 in the circumferential direction.

[0089] The diameter of the tabletop 10 is 100 mm. The thickness of the reinforcing rib 30 is 3 mm.

[0090] In the shock acceleration verification experiment based on Embodiment 1: Without the reinforcing ribs, the deviation value between each first fixing position 21 and the second fixing position 22 at the center is between 45% and 48%; compared with Embodiment 1, the deviation value between the same first fixing position 21 and the second fixing position 22 is between 10% and 15%, and the deviation value is reduced by at least 30%, which well solves the problem of shock acceleration attenuation.

[0091] Embodiment 2

[0092] As Figure 4 shown, another embodiment of the sensor support structure for the PIND detection device of the present application is provided, including a circular tabletop 10. The tabletop 10 is provided with 4 fixing positions 20 for fixing sensitive elements. The tabletop 10 is connected with reinforcing ribs 30.

[0093] Among them, the fixing position 20 is in a groove shape, including 4 first fixing positions 21, and the first fixing positions 21 are annularly distributed and arranged in a cross shape about the center of the tabletop 10.

[0100] As described in the embodiments, when two or more sensitive elements are applied in the composite sensor, for the corresponding detection areas, except for the sensitive element disposed at the center, the detection areas corresponding to the sensitive elements at other positions will have the problem of impact acceleration deviation, and this problem will become more serious as the number of detection points increases.
