Description

Technical Field

[0001] The invention relates to the field of intelligent sensor production and manufacturing, and in particular to a tilt sensor debugging and reversing device. Background Art

[0002] At present, in the debugging process of inclination sensor products, there are single-axis, dual-axis, three-axis and dynamic inclination sensor products, and different types of inclination sensor products have different detection and use requirements. For single-axis inclination sensors, it is only necessary to install the tooling fixture on the single-axis high-precision turntable, and the entire debugging process of the sensor can be realized by clamping once; however, for dual-axis sensors, if a single-axis high-precision turntable is also used, secondary clamping and positioning operations will be required during the debugging process, that is, after debugging one axis, the dual-axis inclination sensor to be tested is removed and installed in a different direction, and then the other axis is debugged. During the debugging process of the same product, not only does it need to be clamped twice, but different positioning devices also need to be set on the tooling fixture. If multiple products are debugged at the same time, it will cause frequent clamping operations by the operator, affecting the debugging efficiency. At the same time, positioning devices in different axis directions need to be set on the tooling fixture, which is difficult to be compatible with products of different models. Therefore, a dual-axis reversing debugging device is needed that can meet the debugging of single-axis products and dual-axis products, and can also reduce the operation of the debugging personnel. Summary of the invention

[0003] In order to solve the technical problems in the background technology, the present invention provides a tilt sensor debugging reversing device, which is used to realize the reversing positioning of the tilt sensor during the debugging process. The device includes:

[0004] The dual-axis reversing assembly includes a horizontal mounting plate mounted horizontally on a turntable, a mounting disc mounted vertically and rotatably on the horizontal mounting plate via a rotating shaft, and a reversing positioning unit;

[0005] Product clamping assembly: used to press and fix multiple products to be tested installed on the mounting position of the mounting disc.

[0006] Furthermore, the horizontal mounting plate is fixed to the turntable via a horizontal mounting plate base and is kept horizontal via a support block.

[0007] Furthermore, the upper end of the rotating shaft is fixed to the bottom surface of the mounting disc through a circular flange, and the lower end passes through the horizontal mounting plate and is fixed by toothed flange bolts, and two upper and lower bearings are provided between the rotating shaft and the horizontal mounting plate to ensure the vertical rotation of the rotating shaft.

[0008] Furthermore, the reversing positioning unit includes a clockwise reversing positioning subunit or a counterclockwise reversing positioning subunit, and the clockwise reversing positioning subunit and the counterclockwise reversing positioning subunit both include a limit block fixed at the 0° position of the horizontal mounting plate and two sets of limit blocks and indexing plunger pins arranged on the mounting disc.

[0009] Furthermore, the limit stopper includes a stopper base and a positioning portion and a groove body portion arranged in a Z shape on the stopper base, and two asymmetric grooves are arranged in the groove body portion. The cross-sections of the two asymmetric grooves are both right-angled trapezoids with the same slope, and the slopes of the two asymmetric grooves are arranged opposite to each other.

[0010] Furthermore, the groove body is provided with a first positioning surface on the side close to the center line of the limit stop block, and the positioning portion is provided with a second positioning surface on the side close to the center line of the limit stop block. The inclined surface direction of the asymmetric groove in the groove body close to the center of the limit stop block is toward the center line of the limit stop block, and the inclined surface direction of the asymmetric groove away from the center of the limit stop block is away from the center line of the limit stop block.

[0011] Furthermore, four mounting positions for installing the limit block and the indexing plunger pin are respectively provided on the mounting disc, the first mounting position and the second mounting position are respectively arranged at the 0° position of the mounting disc, and the distance between the first mounting position and the center of the mounting disc is greater than the distance between the second mounting position and the center of the mounting disc, the third mounting position is located at the +90° position of the mounting disc, and the distance between the third mounting position and the center of the mounting disc is the same as the distance between the second mounting position and the center of the mounting disc, and the fourth mounting position is located at the -90° position of the mounting disc, and the distance between the fourth mounting position and the center of the mounting disc is the same as the distance between the first mounting position and the center of the mounting disc.

[0012] Further, in the clockwise reversing positioning subunit, two limit blocks are respectively fixed at the 0° position and -90° position of the bottom surface of the mounting disc, and two indexing plunger pins are respectively fixed at the 0° position and -90° position of the surface of the mounting disc;

[0013] In the counterclockwise reversing positioning subunit, two limit blocks are respectively fixed at the 0° position and +90° position of the bottom surface of the mounting disc, and two indexing plunger pins are respectively fixed at the 0° position and +90° position of the surface of the mounting disc.

[0014] Furthermore, for the inclination sensor product with a circular shell, the product clamping assembly includes a vertical toggle clamp installed on the mounting disc through an toggle clamp pad and a pressure plate with a plurality of circular holes, and a buffer gasket is provided at the circular hole; for the inclination sensor product with a non-circular shell, the product clamping assembly includes a vertical toggle clamp installed on the mounting disc through an toggle clamp pad, and each product to be tested corresponds to a set of vertical toggle clamps and toggle clamp pads.

[0015] Furthermore, the slope of the inclined surface ranges from 60° to 70°.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The single-axis high-precision turntable has limited carrying capacity. The present invention avoids the use of a motor that is too heavy, which would cause the commutation assembly to be too complicated, making the entire tooling more concise and reducing the weight of the entire commutation assembly. It can carry more products to be installed and tested and ensure the level of the mounting plate, greatly improving the utilization rate of the single-axis high-precision turntable. It is simple to operate and does not require programming control on the host computer. It overcomes the shortcomings of inaccurate positioning and easy damage to the motor during the use of automatic control commutation, and eliminates the interference of the motor on the product to be tested.

[0018] 2. The present invention can accurately install and lock the disc for 90° forward and reverse switching, thereby ensuring the accuracy of debugging. In addition, through the limit stop block structure and the installation position corresponding to the forward and reverse switching, the present invention can achieve the conversion of forward and reverse switching without major disassembly, which is more convenient to use, greatly speeds up the debugging efficiency, and reduces the risk of manual debugging. It can not only meet the debugging of single-axis inclination sensors, but also be particularly suitable for the switching debugging of dual-axis inclination sensors.

[0044] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] like Figure 1-3 As shown, the present invention provides a tilt sensor debugging and reversing device, which is used to implement the debugging and testing process of the tilt sensor product to be tested, especially the dual-axis tilt sensor product that needs reversing. The device is installed on a single-axis high-precision turntable 100, and the single-axis high-precision turntable 100 is automatically controlled by a host computer, specifically including:

[0046] Double-axis reversing assembly: including a horizontal mounting plate base 201, a horizontal mounting plate 202, a support block 203, a bearing pressure block, a rotating shaft 205, a bearing retaining ring, a bearing, a toothed flange bolt 208, a mounting disc 209, a limit stopper 210, a limit block 211 and an indexing plunger pin 212;

[0047] The product clamping assembly includes a vertical toggle clamp 302 and a toggle clamp pad, a positioning column 303, a pressure plate 304 with a buffer washer 305, and a product positioning block 308.

[0048] The structure and working principle of each component of the device are introduced below.

[0049] like Figure 4 As shown, in the dual-axis reversing assembly, a shaft hole is provided in the middle of the horizontal mounting plate 202, and an upper bearing mounting hole and a lower bearing mounting hole for mounting bearings are respectively provided around the shaft hole on the upper and lower surfaces of the horizontal mounting plate 202 (the apertures of the upper and lower bearing mounting holes are larger than the shaft hole), the lower portion of the upper bearing 2071 is embedded in the upper bearing mounting hole, and the upper portion is embedded in the step hole of the upper bearing pressing block 2041, thereby limiting the upper bearing 2071 in the space formed by the upper bearing mounting hole and the step hole of the upper bearing pressing block 2041; the upper portion of the lower bearing 2072 is embedded in the lower bearing mounting hole, and the lower portion is embedded in the step hole of the lower bearing pressing block 2042, thereby limiting the lower bearing 2072 in the space formed by the lower bearing mounting hole and the step hole of the lower bearing pressing block 2042;

[0050] The upper bearing block 2041 and the lower bearing block 2042 are fixed to the threaded holes on the horizontal mounting plate 202 by screws respectively. An upper bearing retaining ring 2061 is installed between the upper bearing 2071 and the lower bearing 2072, and a lower bearing retaining ring 2062 is installed on the lower side of the lower bearing 2072 to limit the movement of the inner ring of the bearing.

[0051] The upper end of the rotating shaft 205 is provided with a circular flange 2051, and a plurality of pin holes and threaded holes are provided on the circular flange 2051. The upper end of the rotating shaft 205 is fixed to the center of the bottom surface of the mounting disc 209 by means of positioning pins and screws, so as to realize the synchronous rotation of the rotating shaft 205 and the mounting disc 209. A threaded through hole is provided at the center of the rotating shaft 205, and its lower end is tightened by the toothed flange bolt 208 after passing through the rotating shaft hole, the inner rings of the upper and lower bearings, and the two bearing retaining rings, so as to ensure that the rotating shaft 205 will not be loosened during the rotation process. The lower bearing retaining ring 2062 is provided between the toothed flange screw 208 and the lower bearing 2072 so as not to directly contact the lower bearing 2072 during the locking process of the toothed flange screw 208, so as to avoid damage to the lower bearing 2072.

[0052] like Figure 1 and 2 As shown, a pin hole and a threaded hole are provided on one side end face of the horizontal mounting plate 202, and the horizontal mounting plate 202 is fixed to the horizontal mounting base plate 201 by pins and screws, and two support blocks 203 are provided between the horizontal mounting plate 202 and the horizontal mounting plate base 201 to ensure that the horizontal mounting plate 202 and the horizontal mounting base plate 201 are vertically arranged, and at the same time disperse the radial force acting on the fixing screws between the horizontal mounting plate 202 and the horizontal mounting base plate 203, reduce the sagging of the horizontal mounting plate 202 caused by gravity, ensure the horizontality of the horizontal mounting plate 202, and one side of the horizontal mounting plate base 201 is fixed to the single-axis high-precision turntable, so that the dual-axis reversing assembly as a whole rotates with the single-axis high-precision turntable 100.

[0053] The lower surface of the horizontal mounting plate 202 is provided with three 24-pin quick-connect terminals 214 for communicating with the host computer, and the lower surface of the mounting disc 209 is provided with eight 8-pin quick-connect terminals 213, one end of which is connected to the 24-pin quick-connect terminal 214, and the other end is connected to the product to be tested 306 via a wire with a connector.

[0054] like Figure 5As shown, the mounting disc 209 is respectively provided with a first mounting position A, a second mounting position B, a third mounting position C and a fourth mounting position D, each mounting position is provided with a mounting positioning hole for mounting a limit block 211 and a dividing plunger pin 212, the first mounting position A and the second mounting position B are respectively arranged at the 0° position of the mounting disc 209, and the first mounting position A is farther from the center of the mounting disc 209 than the second mounting position B, the third mounting position C is arranged at the -90° position of the mounting disc 209, and the third mounting position C and the first mounting position A are located on the same circumference (the distance between the third mounting position C and the first mounting position A to the center of the mounting disc 209 can be fine-tuned according to actual conditions, and may not be limited to the same circumference to adapt to different models and sizes The fourth mounting position D is set at the +90° position of the mounting disc 209, and the fourth mounting position D and the second mounting position B are located on the same circumference (the distances from the fourth mounting position D and the second mounting position B to the center of the mounting disc 209 can be fine-tuned according to actual conditions, and may not be limited to the same circumference to accommodate products 306 of different models and sizes). In this example, the position of the mounting disc 209 rotated 90° counterclockwise from the 0° position is defined as the -90° position, and the position of the mounting disc 209 rotated 90° clockwise from the 0° position is defined as the +90° position. The indexing plunger pin 212 is installed on the upper surface of the mounting disc 209, and the limit block 211 adopts a square limit block and is installed on the lower surface of the mounting disc 209.

[0055] The present invention can meet the debugging conditions of different rotation directions. For the condition that clockwise reversing is required, the corresponding limit blocks 211 and indexing plunger pins 212 need to be installed on the second mounting position B and the third mounting position C on the upper surface of the mounting disc 209, and the corresponding limit blocks 211 need to be installed at the 0° and -90° positions on the lower surface; for the condition that counterclockwise reversing is required, the corresponding limit blocks 211 and indexing plunger pins 212 need to be installed on the first mounting position A and the fourth mounting position D on the upper surface of the mounting disc 209, and the corresponding limit blocks 211 need to be installed at the 0° and +90° positions on the lower surface; it should be noted that clockwise reversing and counterclockwise reversing cannot exist at the same time, otherwise the mounting disc 209 cannot rotate.

[0056] In order to cooperate with the indexing plunger pin 212 and the limit block 211, so that the mounting disk 209 can be accurately positioned at the +90° position or the -90° position when performing clockwise or counterclockwise reversing operations, the present invention opens an installation positioning hole for the limit block 210 at the 0° position on the upper surface of the horizontal mounting plate 202, and fixes the limit block 210 at the 0° position on the upper surface of the horizontal mounting plate 202 by pins and screws.

[0057] like Figure 6a and 6bAs shown, the limit stopper 210 includes a stopper base, a positioning portion and a slot body portion arranged on the stopper base, and two asymmetric slots (a first trapezoidal slot a and a second trapezoidal slot b) are arranged in the slot body portion. In this example, the length of the first trapezoidal slot a is 14 mm, and the length of the second trapezoidal slot b is 10 mm. In actual use, they can be adjusted according to specific usage requirements. The first trapezoidal slot a and the second trapezoidal slot b are jointly arranged at the upper left position of the stopper base, the positioning portion is arranged at the lower right position of the stopper base, and the central mounting hole is arranged at the center of the limit stopper 210. The cross-sections of the first trapezoidal slot a and the second trapezoidal slot b are both right-angled trapezoids with the same slope (the slope range is 60° to 70°, 60° in this example), but the right-angle sides of the two are arranged relative to each other, and the positioning portion cooperates with the corresponding limit block 211 to realize the positioning at 0° or ±90° during the rotation of the mounting disc 209, as shown in FIG. Figure 6c and 6d As shown, the first trapezoidal groove a and the second trapezoidal groove b cooperate with the corresponding indexing plunger pin 212 to achieve position locking and produce reverse pressing force after the mounting disc 209 rotates to the 0° or ±90° position.

[0058] In this example, the first trapezoidal groove a is closer to the central mounting hole of the limit stop 210 than the second trapezoidal groove b, and the inner side surface of the groove body of the limit stop 210 close to the center line is set as the first positioning surface c, and the inner side surface of the positioning part close to the center line is set as the second positioning surface d.

[0059] The working principle of the present invention is as follows:

[0060] 1. Clockwise rotation reversing condition

[0061] like Figure 7 and Figure 8 As shown, facing the turntable 100, if the disc 209 needs to be installed for clockwise rotation and reversing, the first limit block 2111 is installed at the 0° position on the lower surface of the installation disc 209, the second limit block 2112 is installed at the -90° position, and the first indexing plunger pin 2121 and the second indexing plunger pin 2122 are installed correspondingly on the installation positioning holes at the second installation position B and the third installation position C;

[0062] When the mounting disc 209 is at the 0° position, the limiting surface of the first limiting block 2111 located at the second mounting position B contacts the second positioning surface d of the limiting stopper 210, thereby limiting the counterclockwise rotation of the mounting turntable 209. At this time, the first indexing plunger pin 2121 is pushed down, and its cylindrical end contacts the inclined surface of the first trapezoidal groove a on the limiting stopper 210. Due to the existence of the inclined surface, during the process in which the cylindrical end of the first indexing plunger pin 2121 continues to slide downward, the force of the inclined surface on the cylindrical end of the first indexing plunger pin 2121 will A horizontal component force is generated, which will push the mounting disc 209 to rotate counterclockwise. However, since the first limit block 2111 has been in contact with the second positioning surface d of the limit block 210, the mounting disc 209 cannot continue to rotate counterclockwise. At this time, the role of this horizontal component force is to maintain the close contact between the first limit block 2111 and the second positioning surface d of the limit block 210. During the process of the entire reversing assembly following the rotation of the single-axis high-precision turntable 100, the mounting disc 209 can always maintain the 0° position unchanged.

[0063] When the mounting disc 209 needs to be rotated 90° clockwise from the 0° position, first pull up the first indexing plunger pin 2121 at the second mounting position B vertically and rotate 90° to unlock it, and then the mounting disc 209 can be rotated clockwise. Fig. 9 As shown, after the mounting disc 209 rotates clockwise from the 0° position to the +90° position, the second limit block 2112 located at the -90° position on the mounting disc 209 contacts the first positioning surface c of the limit stop 210, thereby limiting the mounting disc 209 from continuing to rotate clockwise. At this time, the second indexing plunger pin 2122 located at the -90° position on the mounting disc 209 is pushed down, and its cylindrical end contacts the inclined surface of the second trapezoidal groove b on the limit stop 210. Due to the existence of the inclined surface, the cylindrical end of the second indexing plunger pin 2122 continues to slide downward. The force at the cylindrical end of the second indexing plunger pin 2122 will generate a horizontal component force, which will push the mounting disc 209 to rotate clockwise. However, since the second limit block 2112 has been in contact with the first positioning surface c of the limit block 210, the mounting disc 209 cannot continue to rotate clockwise. At this time, the role of this horizontal component force is to maintain the close contact between the second limit block 2112 and the first positioning surface c of the limit block 210. During the process of the entire reversing assembly following the rotation of the single-axis high-precision turntable 100, the mounting disc 209 can always remain at the +90° position unchanged.

[0064] 2. Counterclockwise rotation reversing condition

[0065] Similar to the clockwise rotation commutation condition, Fig.10 and Fig.11As shown, facing the turntable 100, if the disc 209 needs to be installed to rotate counterclockwise, the third limit block 2113 is installed at the 0° position on the lower surface of the installation disc 209, and the fourth limit block 2114 is installed at the +90° position, and the third indexing plunger pin 2123 and the fourth indexing plunger pin 2124 are installed on the installation positioning holes at the first installation position A and the fourth installation position D respectively;

[0066] When the mounting disc 209 is at the 0° position, the limiting surface of the third limiting block 2113 located at the first mounting position A contacts the first positioning surface c of the limiting stopper 210, thereby limiting the clockwise rotation of the mounting turntable 209. At this time, the third indexing plunger pin 2123 is pushed down, and its cylindrical end contacts the inclined surface of the second trapezoidal groove b on the limiting stopper 210. Due to the existence of the inclined surface, during the process in which the cylindrical end of the third indexing plunger pin 2123 continues to slide downward, the force of the inclined surface on the cylindrical end of the third indexing plunger pin 2123 will A horizontal component force is generated, which will push the mounting disc 209 to rotate clockwise. However, since the third limit block 2113 has been in contact with the first positioning surface c of the limit block 210, the mounting disc 209 cannot continue to rotate clockwise. At this time, the role of this horizontal component force is to maintain the close contact between the third limit block 2113 and the first positioning surface c of the limit block 210. During the process of the entire reversing assembly following the rotation of the single-axis high-precision turntable 100, the mounting disc 209 can always maintain the 0° position unchanged.

[0067] When the mounting disc 209 needs to be rotated 90° counterclockwise from the 0° position, first pull up the third indexing plunger pin 2123 at the first mounting position A vertically and rotate 90° to unlock it, and then the mounting disc 209 can rotate counterclockwise. Fig.12 As shown, after the mounting disc 209 rotates counterclockwise from the 0° position to the -90° position, the fourth limit block 2114 located at the +90° position on the mounting disc 209 contacts the second positioning surface d of the limit stop 210, thereby limiting the mounting disc 209 from continuing to rotate counterclockwise. At this time, the fourth indexing plunger pin 2124 at the +90° position on the mounting disc 209 is pushed down, and its cylindrical end contacts the inclined surface of the first trapezoidal groove a on the limit stop 210. Due to the existence of the inclined surface, during the process in which the cylindrical end of the fourth indexing plunger pin 2124 continues to slide downward, the inclined surface contacts the first trapezoidal groove a on the limit stop 210. The force at the cylindrical end of the four-dividing plunger pin 2124 will generate a horizontal component force, which will push the mounting disc 209 to rotate counterclockwise. However, since the fourth limit block 2114 has been in contact with the second positioning surface d of the limit block 210, the mounting disc 209 cannot continue to rotate counterclockwise. At this time, the role of this horizontal component force is to maintain the close contact between the fourth limit block 2114 and the second positioning surface d of the limit block 210. During the process of the entire reversing assembly following the rotation of the single-axis high-precision turntable 100, the mounting disc 209 can always maintain a -90° position unchanged.

[0068] Example 1

[0069] The circular housing requires three holes for the installation of the inclination sensor product

[0070] like Fig.13 As shown, 8 groups of positioning columns are arranged on the installation disc 209, 3 in each group, which can be arranged according to the height size and installation hole spacing of different products to install the inclination sensor products to be tested. The positioning columns must be arranged to ensure the consistency of the directions of the 8 products after installation, so as to facilitate parallel debugging. The installation disc 209 is also provided with 4 groups of vertical elbow clamps and the installation holes corresponding to the first elbow clamp pad 301. Two groups of vertical elbow clamps 302 and pads can be installed diagonally according to needs, or all four groups of vertical elbow clamps 302 and pads can be installed. In addition to the vertical elbow clamp 302 itself having a certain height adjustment range, the first elbow clamp pad 301 can be adjusted according to the height of different products 306 to be tested. After the 8 products 306 to be tested are installed on the positioning columns 303, all the products 306 to be tested are pressed and fixed by a perforated pressure plate 304, and then the pressure plate 304 is pressed by the vertical elbow clamp 302, so that the 8 products 306 to be tested are completely pressed indirectly.

[0071] like Fig.14 As shown, in order to prevent the area on the pressing plate 304 close to the pressing point of the vertical elbow clamp 302 from being deformed and dented due to large force, and the area on the pressing plate 304 far from the pressing point of the vertical elbow clamp 302 from warping and causing the product 306 to fail to be pressed tightly, in this example, a buffer washer 305, such as EVA sponge, is added at the pressing position corresponding to each product 306 to be tested on the back of the pressing plate 304; the buffer washer 305 is set to be relatively thin at a position closer to the pressing point of the vertical elbow clamp 302, and the buffer washer 305 is set to be relatively thick at a position farther from the pressing point of the vertical elbow clamp 302, so that the 8 products 306 to be tested can be pressed tightly, and at the same time, the products 306 to be tested can be prevented from being crushed.

[0074] like Fig.15 As shown, 8 product positioning blocks 308 are arranged on the installation disk 209, and 8 groups of vertical toggle clamps 302 and installation holes of the second toggle clamp pad 307 are arranged. The product positioning blocks 308 are used to realize the positioning of the product 306 to be tested (a square shell in this example), and then the vertical toggle clamps 302 are used to press the products 306 to be tested. The setting of the product positioning blocks 308 must ensure the consistency of the directions of the 8 products 306 to be tested after installation, so as to perform parallel debugging. In addition to the vertical toggle clamp 302 itself having a certain height adjustment range, the second toggle clamp pad 307 can also be adjusted according to the height of different products to be tested.

[0075] After all the products to be tested 306 are installed, the automatic debugging software of the host computer is started to automatically control the single-axis high-precision turntable 100 to rotate according to the set program. When the current axis debugging of the product to be tested 306 is completed and a 90° rotation reversal is required to debug the second axis, the indexing plunger pin 212 is pulled up to release the lock of the limit block 210, and then the indexing plunger pin 212 is pressed down to lock the limit block 210 at the corresponding position after rotating 90° clockwise / counterclockwise to the corresponding position as required, and then the debugging of the second axis is continued. After completing the debugging tasks of the two axes, the vertical elbow clamp 302 is opened, the thread is removed, and the debugged product to be tested 306 is removed to complete the debugging of the current batch of products to be tested 306.

[0076] In summary, the present invention provides a tilt sensor debugging and reversing device, which can accurately install the disc for 90 degrees of forward and reverse reversing and lock it at the ±90 degree position by setting a limit block with a trapezoidal groove and a positioning portion to cooperate with the dividing plunger pin and the limit block in the corresponding position, thereby ensuring the accuracy of debugging. In addition, through the specially designed limit block structure and the corresponding installation position for forward and reverse reversing, the present invention can achieve the conversion of forward and reverse reversing without major disassembly, which is more convenient to use, greatly speeds up the debugging efficiency, and reduces the risk of manual debugging. It can not only meet the debugging of single-axis tilt sensors, but also be particularly suitable for the commutation debugging of dual-axis tilt sensors.

[0077] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
