Abstract
Description
Technical Field
[0001] The present application relates to the field of calibration instrument tooling, and in particular to an elastic seat for calibrating a sensor module. Background Art
[0002] Commonly used electronic component carrier materials in sensors include printed circuit boards, ceramic substrates and plastic packaging.
[0003] Ceramic substrates are mainly used for installing and wiring high-performance electronic components. They have good stability, strong anti-interference ability and excellent reliability. This is mainly because ceramic materials have high insulation and low thermal expansion coefficients, and have high dielectric properties. Ceramic electronic components have high transmission efficiency for very small electrical signals and can work stably for a long time. Therefore, they are widely used in high-precision electronic systems. Sensors that use ceramic substrates as electronic component carriers need to calibrate the precision of the ceramic module before they are produced.
[0004] In the prior art, in order to process ceramic carrier electronic components in batches, a tray with array-arranged plug-in slots is usually used, one ceramic carrier electronic component is placed in each slot, and finally a calibration instrument is used to calibrate the batch of ceramic carrier electronic components on the tray. Usually, an elastic seat is provided in the calibration instrument corresponding to the tray to assist the calibration work.
[0005] Reference Figure 1 The elastic seat in the prior art includes an upper plug-in board 1 and a lower support board 2 arranged in parallel from top to bottom, and the tray 01 is plugged into the top surface of the upper plug-in board 1. The distance between the upper plug-in board 1 and the lower support board 2 is 1 to 3 mm, and a plurality of precision springs 3 are abutted on the opposite sides of the upper plug-in board 1 and the lower support board 2. In order to keep the upper plug-in board 1 and the lower support board 2 stable during the calibration vibration process, a plurality of guide rods 4 arranged perpendicular to the upper plug-in board 1 are plugged between the upper plug-in board 1 and the lower support board 2, and a ball 41 is embedded around each guide rod 4.
[0006] The elastic seat used in the prior art can reduce the possibility of ceramic carrier electronic components being compressed, damaged or even cracked when the calibration instrument is cutting, grinding or hammering the ceramic carrier electronic components, thereby protecting the ceramic carrier electronic components. However, the gap between the upper plug-in plate and the lower support plate is too small, the precision springs and guide rods embedded with balls are too expensive, and the process of making the elastic seat is too complicated, making it inconvenient for mass production. Utility Model Content
[0007] In order to reduce the manufacturing cost of the elastic seat and simplify the manufacturing difficulty of the elastic seat, the present application provides an elastic seat for calibrating a sensor module.
[0008] The elastic seat for calibrating a sensor module provided in the present application adopts the following technical solution:
[0009] An elastic seat for calibrating a sensor module comprises, from top to bottom, an upper plug-in plate for receiving a tray and a lower support plate located on the side of the upper plug-in plate facing away from the tray, a plurality of elastic sheets are arranged around the upper plug-in plate and the lower support plate on the same side, each of the elastic sheets is bent and the open end faces the upper plug-in plate and the lower support plate, one open end of each of the elastic sheets is connected to the side wall of the upper plug-in plate, and the other end is connected to the side wall of the lower support plate.
[0010] By adopting the above technical solution, when the operator places the tray carrying several ceramic carrier electronic components on the upper plug-in board, the elastic seat supported by several elastic sheets is sent into the calibration instrument. When the calibration instrument is chip grinding or hammering the ceramic carrier electronic components, since the initial spacing between the upper plug-in board and the lower support plate is only 1 to 3 mm, the elastic deformation that the elastic sheet needs to bear is very small. Elastic sheets with better elastic materials can reduce the possibility of excessive pressure causing damage or even brittle cracking of the ceramic carrier electronic components, and several elastic sheets are arranged on the side walls on the same side of the upper plug-in board and the lower support plate, which reduces the possibility of the upper plug-in board being staggered with the lower support plate when it approaches the lower support plate. The elastic sheet replaces the precision spring and the guide rod with a ball, which not only greatly reduces the production cost of the elastic seat, but also greatly simplifies the production difficulty of the elastic seat.
[0011] Optionally, a placement groove is provided on the top surface of the upper plug-in board corresponding to the tray, and a plurality of clearance grooves are provided on the top surface of the upper plug-in board corresponding to the entry and exit points of the milling cutter, and the plurality of clearance grooves are close to the edge of the placement groove and are connected to the placement groove.
[0012] By adopting the above technical solution, when the calibration instrument needs to perform cutting processing on the end faces of several ceramic carrier electronic components on the tray, the provision of several clearance grooves can avoid excessive impact force when the tool enters the workpiece, reduce the influence of vibration and cutting force, and thus ensure smooth processing; similarly, when the tool cuts out, the tool retreats to the clearance groove, which can effectively reduce the sudden change of cutting force, reduce the influence on the workpiece, and thus improve the processing accuracy.
[0013] Optionally, a groove is provided on the top surface of the upper plug-in board to facilitate operators to take the tray.
[0014] By adopting the above technical solution, the operator can place and take the tray by putting his hands into the grooves below the two opposite sides of the tray. The setting of the grooves improves the convenience of placing and taking the tray.
[0015] Optionally, plug strips are provided on both sides of the end of the elastic sheet, and limiting frames are provided on the side walls of the upper plug board and the lower support plate close to the elastic sheet corresponding to the plug strips, and a single plug strip is plugged into a single limiting frame.
[0016] By adopting the above technical solution, the elastic recovery ability of the elastic sheet will be greatly weakened after long-term use, and it needs to be replaced after a certain number of uses. The elastic sheet can be detachable from the upper plug-in board and the lower support plate through the plug-in cooperation of the plug-in strip and the limit frame, avoiding the entire scrapping of the elastic seat after a certain number of uses, thereby reducing the calibration cost of ceramic carrier electronic components.
[0017] Optionally, the elastic sheet is coated with polytetrafluoroethylene.
[0018] By adopting the above technical solution, the polytetrafluoroethylene material has the characteristic of being resistant to distortion. When the elastic sheet is coated with polytetrafluoroethylene, it helps to increase the service life of the elastic sheet.
[0019] Optionally, ear plates are provided on both sides of the end of the elastic sheet corresponding to the plug-in strip, and each ear plate is provided with a fixing member for connection with the corresponding plug-in strip.
[0020] By adopting the above technical solution, the elastic sheet and the plug-in strip are fixedly connected by a fixing piece, so that the connection between the elastic sheet and the plug-in strip is both stable and easy to disassemble, thereby reducing the cost of replacing parts of the elastic seat.
[0021] Optionally, the plug strip has limiting grooves distributed along its length direction on one side away from the elastic sheet, a ball is rotatably arranged in each limiting groove, and a portion of the ball extending out of the limiting groove abuts against an inner wall of the limiting frame.
[0022] By adopting the above technical solution, the provision of the rolling ball reduces the friction force generated when the plug-in strip is plugged into the limiting frame, making it easier for the plug-in strip to be plugged into the limiting frame.
[0023] Optionally, a compression spring is arranged in the limit groove along a direction perpendicular to the length of the plug-in strip, the compression spring is limited in the limit groove, the part of the ball located in the limit groove is sleeved in the compression spring, and a snap-in groove is opened on the inner side wall that contacts the limit frame corresponding to each ball, and when the plug-in strip is fully inserted into the limit frame, each ball is snap-fitted into the corresponding snap-in groove.
[0024] By adopting the above technical solution, the locking fit between the rolling ball and the locking groove facilitates the limiting of the plug-in strip after it is fully inserted into the limiting frame, and the setting of the compression spring supports the rolling ball to enter and leave the locking groove.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. After the operator places the tray carrying several ceramic carrier electronic components on the upper plug board, the elastic seat supported by several elastic sheets is sent into the calibration instrument. When the calibration instrument is cutting, grinding or hammering the ceramic carrier electronic components, since the initial spacing between the upper plug board and the lower support plate is only 1 to 3 mm, the elastic deformation that the elastic sheet needs to bear is very small. Elastic sheets made of better elastic materials can reduce the possibility of damage or even brittle cracking of the ceramic carrier electronic components due to excessive pressure, and several elastic sheets are arranged on the side walls on the same side around the upper plug board and the lower support plate, which reduces the possibility of the upper plug board being misaligned with the lower support plate when it approaches the lower support plate. The elastic sheets replace the precision springs and the guide rods with ball bearings, which not only greatly reduces the production cost of the elastic seat, but also greatly simplifies the difficulty of making the elastic seat;
[0027] 2. When the calibration instrument needs to cut the end faces of several ceramic carrier electronic components on the tray, the setting of several clearance grooves can avoid excessive impact force when the tool enters the workpiece, reduce the influence of vibration and cutting force, and thus ensure the smooth progress of the processing; similarly, when the tool is cutting out, the tool retreats to the clearance groove, which can effectively reduce the sudden change of cutting force and reduce the influence on the workpiece, thereby improving the processing accuracy;
[0028] 3. The operator can place and take the tray by putting his hands into the grooves at the bottom of the tray on both sides away from each other. The setting of the grooves improves the convenience of placing and taking the tray. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 2-5 This application is described in further detail.
[0037] An embodiment of the present application discloses an elastic seat for calibrating a sensor module.
[0038] Example 1
[0039] Reference Figure 2 An elastic seat for calibrating a sensor module includes an upper plug-in board 1 and a lower support board 2 from top to bottom, and a plurality of elastic sheets 5 are arranged around the upper plug-in board 1 and the lower support board 2 on the same side, and each elastic sheet 5 is bent. In practical applications, the elastic sheet 5 can be bent into a triangle, a bulb shape, a U shape or other open shapes.
[0040] Reference Figure 2 In this embodiment, according to the process requirements, the elastic sheets 5 are arranged in a U shape. Taking four as an example, two elastic sheets 5 form a group. One group of elastic sheets 5 is arranged on the same side of the upper plug-in board 1 and the lower support board 2, and the other group of elastic sheets 5 is arranged on the upper plug-in board 1 and the lower support board 2 on the side away from the group of elastic sheets 5, and the open end of each elastic sheet 5 faces the upper plug-in board 1 and the lower support board 2, and one end of the open end of each elastic sheet 5 is integrally formed on the side wall of the upper plug-in board 1, and the other end is integrally formed on the side wall of the lower support board 2.
[0041] Reference Figure 2 Since the distance between the upper plug-in board 1 and the lower support board 2 is only 1 to 3 mm in actual use, the elastic deformation required for the elastic sheet 5 is very small. Therefore, the requirement for the degree of deformation of the elastic sheet 5 under pressure is relatively low, and most elastic materials can meet the conditions for making the elastic sheet 5.
[0042] Reference Figure 2 A placement groove 11 is provided on the top surface of the upper plug-in board 1 corresponding to the tray 01. In order to facilitate the operator to take the tray 01, two grooves 12 are provided on the top surface of the upper plug-in board 1. The two grooves 12 are respectively located on the opposite sides of the tray 01, and the two grooves 12 are connected to the placement groove 11.
[0043] Reference Figure 2In order to avoid excessive impact force when the tool enters the workpiece during calibration, a plurality of semicircular clearance grooves 13 are provided on the top surface of the upper plug-in plate 1 corresponding to the entry and exit points of the milling cutter. In this embodiment, four of them are taken as an example, which are respectively arranged at the two ends of the placement groove 11 close to the groove 12, and each of the clearance grooves 13 is connected to the placement groove 11.
[0044] Reference Figure 2 In this embodiment, all the right-angled edges of the slots are ground into chamfers to protect the operator's operating safety.
[0045] The implementation principle of the elastic seat for sensor module calibration in the embodiment of the present application is as follows: after the operator places the tray 01 carrying a plurality of ceramic carrier electronic components on the upper plug-in board 1, the elastic seat supported by a plurality of elastic sheets 5 is sent into the calibration instrument. When the calibration instrument is chipping, grinding or hammering the ceramic carrier electronic components, the elastic sheets 5 with elastic properties can reduce the possibility of damage or even brittle cracking of the ceramic carrier electronic components due to excessive pressure.
[0046] Example 2
[0047] Reference Figure 3 , Figure 4 and Figure 5 The difference between this embodiment and the first embodiment is that the elastic sheet 5 is detachably arranged between the upper plug-in board 1 and the lower support board 2. In order to improve the service life of the elastic sheet 5, the elastic sheet 5 is coated with polytetrafluoroethylene.
[0048] Reference Figure 4 A limit frame 6 is fixedly provided on the side walls of the upper plug-in plate 1 and the lower support plate 2 near the end of each elastic sheet 5, and a plug-in strip 7 is inserted in the limit frame 6. Ear plates 51 are integrally formed on both sides of the end of the elastic sheet 5 corresponding to the plug-in strip 7, and each ear plate 51 is provided with a fixing member 8. The fixing member 8 in this embodiment includes a screw 81 and a nut 82. The screw 81 is integrally formed on one side of the plug-in strip 7 near the ear plate 51, and the screw 81 slides through the ear plate 51, and the nut 82 is sleeved on the screw 81 by threaded rotation, and the nut 82 contacts the ear plate 51, and the ear plate 51 is restricted between the nut 82 and the plug-in strip 7.
[0049] Reference Figure 5 In order to make the plug-in cooperation between the plug-in strip 7 and the limit frame 6 more stable, a limit groove 71 is distributed along the length direction of the plug-in strip 7 on the side away from the elastic sheet 5, and the length direction of each limit groove 71 is perpendicular to the length direction of the plug-in strip 7, and a compression spring 9 is arranged in each limit groove 71 along its length direction, and each compression spring 9 is rotatably sleeved with a ball 91 near the open end of the limit groove 71, and part of the ball 91 is located in the compression spring 9, and part of it extends out of the limit groove 71 and contacts the inner wall of the limit frame 6.
[0050] Reference Figure 5 A snap-in groove 61 is provided on the inner side wall of the limit frame 6 that contacts each ball 91 . When the plug-in strip 7 is fully inserted into the limit frame 6 , each ball 91 is snap-fitted into the corresponding snap-in groove 61 .
[0051] The implementation principle of Example 2 is that after long-term use, the elastic recovery ability of the elastic sheet 5 will be greatly weakened, and it needs to be replaced after a certain number of uses. The elastic sheet 5 can be detachable from the upper plug-in board 1 and the lower support board 2 by plugging and cooperating with the plug-in strip 7 and the limit frame 6.
