Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flash gauge structure, and particularly relates to a vertical flash gauge. BACKGROUND

[0002] The flash gauge is a rapid measurement equipment based on the principle of optical imaging, which is mainly used for efficient detection of geometric parameters such as size, shape and position of precision parts. Its core function is to realize non-contact rapid measurement of the measured object through high-speed shooting and image processing technology, which significantly improves the detection efficiency, and is especially suitable for quality control in batch production.

[0003] The flash gauge generally comprises a light source, a measuring device, a stage and a stage glass mounted on the stage. The measuring device is arranged above the stage glass. The light source emits light which passes through the stage glass to irradiate the measured workpiece placed on the stage glass. The profile information of the measured workpiece is acquired by the measuring device, so that the flash gauge can measure the geometric quantities such as length, width, height, hole distance and spacing of the appearance shape of the measured workpiece.

[0004] The stage glass of the flash gauge needs to have good optical performance, such as light transmittance and flatness, so optical glass such as K9 glass is usually selected. However, during use, the glass surface may be scratched due to the roughness of the measured object surface (such as metal burrs and hard particles), friction and sliding during placement, or improper cleaning (using rough cloth and not cleaning foreign matter), which affects the detection effect and needs to be replaced in time.

[0005] In the patent application No. 202211170303.9, a flash gauge with replaceable stage glass is disclosed, which uses first and second elastic mechanisms to fix the stage glass. When replacing the stage glass, special tools are not needed for replacement and installation, thereby improving the convenience of using the flash gauge.

[0006] Although the above-mentioned patent technology realizes quick replacement of the stage glass, the stage glass is still fixed by torsion springs and screws in the technical solution, which is complicated to operate and needs to adjust the torsion springs and screws respectively. In particular, the torsion springs are prone to jump and disengage during installation and adjustment, which is difficult to operate.

[0007] In addition, the carrier table of the flash gauge will tilt after long-term use, and the carrier table glass will also tilt, causing errors in the size of the measured workpiece on the carrier table glass. For example, in the invention patent 202011055107.8, it is mentioned that the screw rod driving the carrier table to move may still produce a small deflection deformation during long-term movement, ultimately causing the remote precision of the carrier table to change. In the present application, the lifting carrier table will also have similar problems during long-term lifting. In addition, the cantilever supporting the lifting carrier table will also change in level due to stress after long-term work, causing the carrier table glass to tilt and causing distortion in the size detection results of the measured workpiece.

[0008] Therefore, there is an urgent need for a technical solution that can quickly replace the carrier table glass, quickly clamp and fix it, and at the same time ensure that the carrier table glass remains level during operation. SUMMARY

[0009] To solve the above problems, the present application provides a vertical flash gauge, which uses a rotating limiting pin instead of a torsional spring to simultaneously press and limit the four corners of the carrier glass plate with the protruding parts on the rotating limiting pin, achieving quick installation and positioning of the carrier glass plate. The entire installation process is quick and convenient. Furthermore, even if the carrier seat tilts, the horizontal state of the carrier glass plate can still be guaranteed due to the support of the spring beads and the horizontal limiting of the pressing plate, thereby improving the size detection accuracy of the measured workpiece.

[0010] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0011] A vertical flash gauge sequentially includes a measurement module, a lifting carrier table, and a base from top to bottom. The lifting carrier table includes a carrier seat and a carrier glass plate lifted by the carrier seat. The four corners of the carrier glass plate are chamfered, and the carrier glass plate is locked and positioned by a locking mechanism installed on the carrier seat. The locking mechanism includes a contact limiting pin at the four corners of the carrier glass plate. When the contact limiting pin rotates synchronously, the protruding parts on the contact limiting pin elastically press and touch the corresponding chamfer of the carrier glass plate, thereby completing the clamping and positioning of the carrier glass plate at one time.

[0012] As an improvement, the carrier seat is square-shaped. The carrier seat is close to or away from the measurement module by lifting. A mounting hole with a stepped structure is formed in the carrier seat. The contact limiting pins are rotatably installed at the four corners of the mounting hole.

[0013] The carrier glass plate is shaped according to the mounting hole. The carrier glass plate is placed on the step of the mounting hole.

[0014] The convex part is arranged in a ball shape, and the convex part is elastically and flexibly arranged between the abutting limiting nails.

[0015] As an improvement, the head of the abutting limiting nail for mounting the convex part is arranged in a hollow shape, an internal spring sleeve is fixedly arranged inside, and a coaxially arranged spring is mounted in the spring sleeve.

[0016] As an improvement, the locking mechanism further comprises a driving assembly for driving the abutting limiting nails to synchronously rotate.

[0017] As an improvement, the driving assembly comprises two groups of transmission units, synchronous belt units, bevel gear units and knobs.

[0018] The transmission unit is a worm gear transmission unit, the worm gears of the transmission units are coaxially and sleevely connected with the corresponding abutting limiting nails, and the worm gears in the same group of transmission units are drivingly connected through a worm.

[0019] The synchronous belt unit drivingly connects the worms in the two groups of transmission units.

[0020] The knob is arranged above any worm, and the knob and the worm are drivingly connected through a bevel gear unit.

[0021] As an improvement, the carrier seat is further provided with at least one prying tongue for lifting the object glass plate, and the prying tongue is driven to synchronously rotate with the abutting limiting nails by the corresponding transmission unit.

[0022] As an improvement, when the abutting limiting nails abut and press and clamp the object glass plate, the prying tongue is retracted into the recovery groove on the carrier seat, and when the abutting limiting nails release the pressing and abutting of the object glass plate, the prying tongue rotates and extends from the recovery groove to lift the object glass plate.

[0023] As an improvement, the carrier seat is embedded with spring glass beads for supporting the object glass plate, and when the carrier seat is tilted, the spring glass beads lift the object glass plate to keep the object glass plate horizontally arranged.

[0024] As an improvement, the upper part of the object glass plate is provided with a horizontally arranged pressing plate, the pressing plate is horizontally overlapped with the object glass plate, and the pressing plate is synchronously lifted with the object glass plate.

[0025] As an improvement, the pressing plate is provided with a correction component for detecting the horizontal state of the pressing plate.

[0026] The beneficial effects of the present application are:

[0027] (1) The present application replaces the torsional spring with a rotary limiting nail, so that the four corners of the object glass plate are simultaneously pressed and limited by the protruding part of the rotary limiting nail, which is more rapid and convenient than adjusting one by one, can greatly shorten the installation and adjustment time, and during the installation process, the protruding part of the rotary limiting nail is in rolling point contact from contacting the object glass plate to pressing the object glass plate, which is more smooth than the linear and surface contact pressing mode of the torsional spring;

[0028] (2) The present application uses a driving assembly to synchronously drive the rotary limiting nail, so that the elastic pressing and limiting of the object glass plate can be completed by only rotating the knob, avoiding the operation mode of rotating the screw with a screwdriver to tighten and adjust the torsional spring, and also avoiding the cumbersome operation process of holding the object glass plate by the operator to press the torsional spring when replacing the object glass plate;

[0029] (3) The present application sets a rotating tongue that rotates synchronously with the rotary limiting nail, which can pry the object glass plate when the rotary limiting nail releases the elastic pressing and limiting of the object glass plate, so that the object glass plate can be smoothly lifted from the installation hole, avoiding the time-consuming and laborious process of prying out the object glass plate from the installation hole when replacing the object glass plate, and also avoiding the disadvantage of breaking the object glass plate and forming glass debris when prying out the object glass plate from the installation hole;

[0030] (4) The present application sets a spring glass bead on the carrier seat, which can lift the object glass plate by adjusting the spring force of the spring inside the spring glass bead, especially when the parallelism of the carrier seat is inclined, the spring glass bead can still lift the object glass plate to overlap with the pressing plate, ensuring the parallelism of the object glass plate and the accuracy of the measured workpiece, so that the measurement accuracy is not affected by the inclination of the carrier seat;

[0031] (5) The present application sets a correction component on the pressing plate, which is measured before each measurement of the measured workpiece, and when the size parameter detected by the correction component deviates from the preset size parameter of the correction component, a signal will be sent out to alarm that the parallelism of the pressing plate deviates and needs to be repaired, avoiding distorted measurement results and enabling timely repair feedback.

[0032] In summary, the present application has the advantages of convenient disassembly and assembly, simple and efficient operation, high detection accuracy, etc., and is especially suitable for the structure of a vertical flash tester. BRIEF DESCRIPTION OF DRAWINGS

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0054] Embodiment 1:

[0055] As Figures 1-11As shown, a vertical flash gauge comprises, from top to bottom, a measurement module 1, a lifting object table 2 and a base 3. The lifting object table 2 comprises a lifting arranged carrier seat 21 and a lifting driven object glass plate 22 by the carrier seat 21. The lifting of the carrier seat 21 is driven by a vertically arranged linear lead screw module 200, and the linear lead screw module 200 and the carrier seat 21 are connected by a cantilever 201. Furthermore, the four corners of the object glass plate 22 are arranged with chamfers, and the object glass plate 22 is locked and positioned by a locking mechanism 23 mounted on the carrier seat 21. The locking mechanism 23 comprises rotating limiting nails 231 at the four corners of the object glass plate 22. When the rotating limiting nails 231 rotate synchronously, the protruding convex portions 232 on the rotating limiting nails 231 elastically extrude and touch the corresponding chamfers of the object glass plate 22, and the object glass plate 22 is clamped and positioned at one time.

[0056] The carrier seat 21 is arranged in a square shape. The carrier seat 21 is arranged to approach or move away from the measurement module 1 by lifting. The carrier seat 21 is provided with a stepped mounting hole 211. The rotating limiting nails 231 are rotatably mounted at the four corners of the mounting hole 211. The object glass plate 22 is arranged in a shape corresponding to the mounting hole 211. The object glass plate 22 is placed on the step of the mounting hole 211. The protruding convex portions 232 are arranged in a ball shape. The protruding convex portions 232 and the rotating limiting nails 231 are elastically arranged.

[0057] First of all, it should be pointed out that the measurement module 1 is composed of an industrial camera 11, a telecentric lens 12 and a multi-zone ring light source 14. The industrial camera is matched with the telecentric lens. Under the illumination of the telecentric parallel light and the multi-zone ring light source, the object to be measured is imaged. The telecentric lens can eliminate the parallax existing in the ordinary lens, ensure that the size of the object imaging is consistent at different object distances, and thus realize high-precision measurement. The telecentric parallel light provides uniform and parallel light, reduces shadow and reflection interference, and ensures that the object surface is uniformly illuminated, which is beneficial to improve the contrast and clarity of the image. The multi-zone ring light source illuminates the object from different angles, highlights the outline and features of the object, and further enhances the image quality, which is convenient for subsequent image analysis and processing.

[0058] Specifically, the object image captured by the industrial camera is analyzed by a software program. The image processing algorithm is used to identify the edge, contour and other features of the object. Then, according to the camera parameters, lens parameters and light source characteristics calibrated in advance, the size, shape and other parameters of the object are calculated. For example, the pixel distance between the edges of the object in the image is measured, and the pixel distance is converted into the actual physical size by combining the resolution and calibration coefficient of the camera, so as to realize accurate measurement of the object.

[0059] Furthermore, it needs to be pointed out that the base 3 is provided with a bottom light source 31 and a refractive lens 32, the bottom light source 31 horizontally emits light, and the refractive lens 32 is arranged obliquely to refract the horizontal light, so that the horizontal light is converted into vertical upward light, so that the light irradiates on the object glass plate 22 to form far zone parallel light, and in addition, the base 3 is externally provided with a button 30 for controlling the measurement module 1.

[0060] It needs to be emphasized that the vertical flash measurement instrument of the present application is different from the existing flash measurement instrument in that the object glass plate 22 of the vertical flash measurement instrument of the present application can be quickly switched, disassembled and assembled, the mounting mode of the object glass plate of the existing flash measurement instrument is very close to the mounting mode of the flash measurement instrument of the present application, both are to open mounting holes for embedding and mounting the object glass plate on the object carrier, and the mounting holes are both arranged in a stepped manner, the object glass plate is supported by the platform of the step, and the clamping and fixing of the object glass plate is realized by the screws penetrating from the side, which is very cumbersome when disassembling and assembling, and at least 2 groups of screws need to be repeatedly screwed, and even up to 8 groups, which is time-consuming and laborious.

[0061] And the present application only needs to synchronously rotate four groups of rotating limiting nails 231 to realize the clamping and fixing of the object glass plate.

[0062] The elastic extrusion structure of the rotating limiting nail 231 is as follows, the head 2311 of the rotating limiting nail 231 for mounting the protruding part 232 is hollowly arranged, and a spring sleeve 233 is fixedly arranged inside, the spring sleeve 233 and the head 2311 are connected by a fastening screw 2312, and the part of the head 2311 for mounting the fastening screw 2312 is vertically arranged to avoid the protruding of the round head of the fastening screw 2312 from the circular edge of the head 2311, and the spring 234 is coaxially arranged in the spring sleeve 233, the protruding part 232 is mounted at the open end of the spring sleeve 233, a pad 230 is arranged between the protruding part 232 and the spring 234, and the protruding part 232 and the pad 230 are relatively rotatably arranged.

[0063] The head 2311 of the initial rotating limiting nail 231 does not abut against the chamfer of the object glass plate 22, but as the rotating limiting nail 231 rotates, the protruding part 232 will rotate to abut against the object glass plate 22, and will gradually extrude the spring 234, as the spring 234 is extruded, the protruding part 232 will abut against the chamfer of the object glass plate 22 to tightly clamp and limit from the four corners of the object glass plate 22 to the center.

[0064] In addition, the synchronous rotating mechanism of the rotating limiting nail 231 is as follows, the locking mechanism 23 further comprises a driving assembly 235 for driving the rotating limiting nail 231 to synchronously rotate.

[0065] Further, the driving assembly 235 comprises two groups of transmission units 236, synchronous belt units 237, bevel gear units 238 and knobs 239;

[0066] The transmission unit 236 is a worm gear transmission unit, the worm gear 2361 of the transmission unit 236 is coaxially connected with the corresponding rotation limiting nail 231, and the upper part of the worm gear 2361 is provided with a ball disc 2320, the ball disc 2320 is fitted on the rotation limiting nail 231, and the ball disc 2320 is in rolling abutment with the carrier seat 21, and the ball disc 2320 also limits the rotation limiting nail 231, avoiding the rotation limiting nail 231 from being separated from the carrier seat 21, and the worm gears 2361 in the same group of transmission units 236 are connected by the worm gears 2362; the synchronous belt unit 237 is connected with the worm gears 2362 in the two groups of transmission units 236; the knob 239 is arranged above any worm gear 2362, and the knob 239 and the worm gear 2362 are connected by the bevel gear unit 238.

[0067] It should be noted that when the knob 239 drives all the rotation limiting nails 231 to rotate synchronously, the rotation of the knob 239 is transmitted to the corresponding group of worm gears 2362 through the bevel gear unit 238, and then the other group of worm gears 2362 is driven to rotate through the synchronous belt unit 237, and then all the worm gears 2361 are rotated through the rotation of the two groups of worm gears 2362, so that all the rotation limiting nails 231 are rotated.

[0068] Embodiment 2:

[0069] Embodiment 2 of the present application is different from embodiment 1 in that:

[0070] As shown in Figure 4 , Figure 6 , Figure 11 , Figure 12 The carrier seat 21 is also provided with at least one group of prying tongues 24 for lifting the object glass plate 22, and the prying tongues 24 are driven to rotate synchronously with the rotation limiting nails 231 by the corresponding transmission units 236.

[0071] When the rotation limiting nail 231 abuts and extrudes the clamping object glass plate 22, the prying tongue 24 is retracted into the recovery groove 210 on the carrier seat 21, and when the rotation limiting nail 231 releases the extrusion of the object glass plate 22, the prying tongue 24 rotates out of the recovery groove 210 and lifts the object glass plate 22.

[0072] It should be noted that, in order to facilitate the removal of the carrier glass plate 22 from the mounting hole 211, a poking tongue 24 is also provided, which is also rotated by the worm gear, and the power source is also the transmission unit 236 from the rotating limiting nail 231. In addition, it should be noted that the poking tongue 24 is provided with a slope surface, and when the poking tongue 24 is lifted, the carrier glass plate 22 moves along the slope surface of the poking tongue 24.

[0073] In addition, when the carrier glass plate 22 is installed, the poking tongue 24 is first recovered, and after the poking tongue 24 is recovered into the recovery groove 210, the protruding portion 232 on the rotating limiting nail 231 begins to resist the chamfer of the carrier glass plate, and then the rotating limiting nail 231 continues to rotate until the protruding portion 232 elastically extrudes the carrier glass plate. The width of the recovery groove 210 is sufficient for the poking tongue 24 to continue to rotate and swing after recovery.

[0074] Example 3:

[0075] The difference between Example 3 and Example 1 and Example 2 is described with reference to Example 1 and Example 2:

[0076] As shown in Figures 13-17 The carrier seat 21 is embedded with a spring ball 25 for supporting the carrier glass plate 22. Specifically, the structure of the spring ball 25 is the same as that of the ball screw, both of which are composed of a shell, a spring and a ball. The spring force is adjusted to make the ball have the effect of lifting the carrier glass plate 22. Therefore, when the carrier seat 21 is inclined, the spring ball 25 can lift the sharp corner of the inclined carrier glass plate 22 to keep the carrier glass plate 22 horizontally arranged. The upper part of the carrier glass plate 22 is provided with a horizontally arranged pressing plate 27, which moves up and down through the sliding rail sliding block module. The pressing plate 27 is horizontally overlapped with the carrier glass plate 22, and is synchronously arranged with the carrier glass plate 22. In this way, when the carrier seat 21 is inclined, the pressing plate 27 will cooperate with the spring ball 25 to horizontally clamp the carrier glass plate 22 in the middle, so that the carrier glass plate 22 is always arranged horizontally.

[0077] Specifically, when the carrier seat 21 is level, the spring glass ball 25 can lift the carrier glass plate 22 by a small distance, and when the carrier seat 21 is inclined, the spring glass ball 25 on the higher side of the carrier seat 21 will be compressed, and the spring glass ball 25 on the lower side of the carrier seat 21 will be extended, through cooperation with the pressing plate 27, so that the carrier glass plate 22 is always in a horizontal state. Of course, in this state, the flash tester is mainly used for measuring lighter measured parts such as PCB boards and chips. For heavy metal parts such as gears, the flash tester is not suitable for detection in this state, because the heavy metal parts will cause the spring glass ball 25 to compress, causing the height of the carrier glass plate 22 to fluctuate, resulting in errors in the measurement results. In addition, the pressing plate 27 is also made of transparent optical glass material, which can avoid the interference of the pressing plate 27 with the measurement data of the measurement module 1 to the measured workpiece.

[0078] The pressing plate 27 is provided with a correction component 271 for detecting the horizontal state of the pressing plate 27. The specific principle of correction is that the correct size of the correction component 271 is first input into the computer for receiving the measurement data of the measurement module 1. Then before each measurement of the flash tester, the measurement module 1 first measures the correction component 271, and then compares the size of the measured correction component 271 with the correct size through the program in the computer. If the comparison result is consistent, it indicates that the horizontal degree of the pressing plate 27 is accurate. If the comparison result is inconsistent, it indicates that the pressing plate 27 is inclined and needs to be corrected.

[0079] It should be further pointed out that the correction component 271 and the pressing plate 27 are detachably arranged. After the correction before measurement is completed, the correction component 271 can be detached from the pressing plate 27, avoiding the interference of the correction component 271 with the measurement of the measured component.

[0080] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
