Description

Technical Field

[0001] This invention relates to the field of visual inspection technology, and in particular to a wide field-of-view flash detector. Background Technology

[0002] A vertical flash measuring instrument, also known as an image measuring machine, is a device that measures objects using microscopic measurement technology. It can not only display the observed object on a display device, but also use computer image processing technology to quickly measure the geometric dimensions of the observed object to generate a measurement map. With the changing measurement needs, flash measuring instruments with a large field of view have also appeared on the market.

[0003] Chinese patent application CN202211170303.9 discloses a vertical flash meter's worktable up-and-down transmission mechanism. This mechanism involves an inner side and a support platform with through holes on the mounting base of the stage. At least two portions of the inner side are equipped with a second elastic mechanism, while a first elastic mechanism is provided on the inner side of the mounting groove. When the stage glass with its slanted side is placed on the support platform of the mounting groove, the second elastic mechanism applies a first force to the stage glass, the inner side of the mounting groove applies a second force, and the first elastic mechanism applies a third force. The combined force of these three forces is zero. Therefore, by using the first and second elastic mechanisms to fix the stage glass, this invention allows for easy replacement of the stage glass without the need for special tools, improving the convenience of the flash meter and reducing damage to the stage glass caused by screws.

[0004] However, this device uses a torsion spring and screws to fix the glass of the stage, which is cumbersome to operate. It requires adjusting the torsion spring and screws separately. In particular, the torsion spring is prone to jumping or coming off during installation and adjustment, making it difficult to operate. Summary of the Invention

[0005] To address the above problems, this invention provides a wide-field-of-view flash meter, which features a lifting mechanism at the four corners of the support base, a centering mechanism and a fixing mechanism around the glass plate, and a turntable mechanism that drives the lifting mechanism, centering mechanism and fixing mechanism in sequence to achieve efficient assembly and disassembly of the glass plate, thus solving the technical problem of difficult assembly and disassembly of the glass plate in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A wide-field-of-view flash detector includes a liftable detection module, a stage, and a bottom light source, arranged sequentially from top to bottom on a mounting platform. The stage includes:

[0008] Support base; the support base is square in shape;

[0009] A glass plate, wherein the glass plate is embedded in the support base;

[0010] A lifting mechanism, comprising several sets of lifting mechanisms evenly distributed at the bottom of the support, wherein the lifting mechanism lifts the glass plate from the support by means of a lifting rod a;

[0011] The centering mechanism is symmetrically arranged in pairs around the glass plate;

[0012] A fixing mechanism, corresponding to the centering mechanism, presses the glass plate after the centering mechanism abuts against the edge of the glass plate. The fixing mechanism includes a top rod b and a pressure plate unit, the top rod b driving the pressure plate unit to press and fix the glass plate from top to bottom; and

[0013] A turntable mechanism is provided inside the mounting platform, and the turntable mechanism alternately cooperates with the top rod a and the top rod b to complete the disassembly and installation of the glass plate.

[0014] As an improvement, the four sets of lifting mechanisms are evenly distributed at the four corners of the support. Each set of lifting mechanisms includes a base plate, a guide cylinder disposed on the base plate, a piston slidably disposed in the guide cylinder and coaxially fixed with the top rod a, a cover plate installed on the end face of the guide cylinder, and a spring a sleeved on the top rod a and in contact with the piston and the base plate. The top rod a is disposed through the base plate and the cover plate.

[0015] As an improvement, the lifting mechanism further includes a guide groove formed on the side wall of the guide cylinder along the length direction of the guide cylinder, and a guide rod disposed on the side of the piston and slidably disposed in the guide groove.

[0016] As an improvement, the centering mechanism includes a vertical plate disposed on the mounting platform, two sets of circular holes symmetrically opened on the vertical plate, a stepped hole coaxially disposed with the circular holes and opened on the side of the vertical plate opposite to the glass plate, a push rod correspondingly inserted through the circular holes and capable of contacting the glass plate, a baffle coaxially disposed on the push rod, and a spring b sleeved on the push rod and located between the baffle and the stepped hole.

[0017] As an improvement, the pressure plate unit includes a movable seat sleeved above the push rod b, a mounting seat mounted on the mounting platform and located in front of the push rod b, two sets of connecting rods a symmetrically hinged on both sides of the movable seat, two sets of connecting rods b symmetrically hinged on both sides of the movable seat and located behind the connecting rods a, two sets of connecting rods c symmetrically hinged on the mounting seat and hinged to the connecting rods a at the middle position, a pressure plate correspondingly hinged to the two sets of connecting rods b and the two sets of connecting rods c, a linear bearing disposed on the mounting platform for mounting the push rod b, and a spring c sleeved on the push rod b and connecting the movable seat and the linear bearing, wherein the connecting rod c is correspondingly abutting against the push rod.

[0018] As an improvement, the pressure plate includes a pressure plate body, a pressure piece disposed at the bottom front side of the pressure plate body and capable of abutting against the glass plate, and an abutting piece disposed at the bottom rear side of the pressure plate body and capable of abutting against the top of the top rod b.

[0019] As an improvement, the turntable mechanism includes a turntable unit rotatably mounted inside the mounting platform and alternately abutting against the top rod a and the top rod b, and a handwheel unit that drives the turntable unit to rotate. The bottom light source generates light that can pass through the turntable unit to illuminate the glass plate.

[0020] As an improvement, the turntable unit includes a rotary support bearing disposed within the mounting platform and below the loading platform, a mounting ring disposed on the rotary support bearing, and a guide block disposed on the mounting ring and capable of abutting against the bottom of both the push rod a and the push rod b.

[0021] As an improvement, the handwheel unit includes a base mounted on the mounting platform, two sets of tapered roller bearings respectively embedded at the upper and lower ends of the base, bearing caps mounted at the upper and lower ends of the base and capable of abutting against the outer rings of the tapered roller bearings, a rotating shaft passing through the two sets of tapered roller bearings, a contact plate coaxially mounted on the rotating shaft and capable of abutting against the inner ring of the lower tapered roller bearing, a locking nut threadedly mounted on the rotating shaft and abutting against the inner ring of the upper tapered roller bearing, a gear coaxially mounted below the rotating shaft and meshing with the slewing support bearing, a handwheel mounted at the top of the rotating shaft, and a clamping seat sleeved on the outside of the rotating shaft and mounted above the upper bearing cap.

[0022] As an improvement, the platform also includes a ring light source mechanism that can be raised and lowered on the support, which includes a vertically arranged linear module and a ring light source disposed between the detection module and the support and which can move up and down with the linear module.

[0023] The beneficial effects of this invention are as follows:

[0024] (1) In this invention, the glass plate is embedded in the support. The corresponding top rod a in the four lifting mechanisms moves up synchronously under the driving action of the turntable mechanism, which can lift the glass plate from the support as a whole, thereby facilitating the disassembly of the glass plate and improving the disassembly efficiency of the glass plate.

[0025] (2) When the glass plate is installed in this invention, the corresponding top rod a in the four lifting mechanisms is in the lifting state. The glass plate is placed on the four top rods a. Then, under the driving action of the turntable mechanism, the four top rods a move down synchronously to send the glass plate into the interior of the support seat, which reduces the collision of the glass plate and realizes the efficient positioning of the glass plate.

[0026] (3) In this invention, after the glass plate is in place, the turntable mechanism drives the top rod b to move and causes the connecting rod c to push the corresponding push rod. Several sets of push rods simultaneously abut against the side of the glass plate, thereby realizing the automatic centering of the glass plate.

[0027] (4) In this invention, after the glass plate is automatically aligned, the pressure plate presses and fixes the edge of the glass plate. The pressure plate presses the glass plate from top to bottom. There will be no sliding friction between the pressure plate and the glass plate, which can effectively prevent the glass plate from shifting during the pressing process and also reduce scratches on the glass plate.

[0028] (5) In this invention, the glass plate is disassembled and assembled by rotating the handwheel. After rotating to the position, it is locked by the clamping seat. This process is simple to operate.

[0029] In summary, this invention has the advantages of simple structure, high efficiency in glass plate assembly and disassembly, and large detection range, and is particularly suitable for the field of flash detection technology. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] Example:

[0047] like Figure 1 and Figure 2 As shown, a wide-field flash detector includes, from top to bottom, a liftable detection module 2, a stage 3, and a bottom light source 4, all mounted on a mounting platform 1. The stage 3 includes:

[0048] Support 31; the support 31 is square in shape;

[0049] Glass plate 32, which is embedded in the support base 31;

[0050] Lifting mechanism 33, several sets of lifting mechanisms 33 are evenly distributed at the bottom of the support 31, the lifting mechanism 33 lifts the glass plate 32 from the support 31 through the top rod a331;

[0051] Centering mechanism 34, the centering mechanisms 34 are symmetrically arranged in pairs around the glass plate 32;

[0052] A fixing mechanism 35 is correspondingly provided with the centering mechanism 34 and presses the glass plate 32 after the centering mechanism 34 abuts against the edge of the glass plate 32. The fixing mechanism 35 includes a top rod b351 and a pressure plate unit 352. The top rod b351 drives the pressure plate unit 352 to press and fix the glass plate 32 from top to bottom.

[0053] Turntable mechanism 36; the turntable mechanism 36 is disposed in the mounting platform 1, and the turntable mechanism 36 alternately cooperates with the top rod a331 and the top rod b351 to complete the disassembly and installation of the glass plate 32.

[0054] Furthermore, the platform 3 also includes an annular light source mechanism 37 that can be raised and lowered on the support 31, which includes a vertically arranged linear module 371 and an annular light source 372 that is arranged between the detection module 2 and the support 31 and can move up and down with the linear module 371.

[0055] It should be noted that the detection module 2 includes a lifting module 21, a telecentric lens 23 that moves up and down with the lifting module 21, and an industrial camera 22 disposed above the telecentric lens 23.

[0056] It should be noted that the bottom light source 4 includes a light source generator 41, a refractive lens 42, and a lens 43. The light source generator 41 emits light horizontally, and the horizontal light is refracted by the tilted refractive lens 42, so that the horizontal light is converted into vertically upward light. The light passes through the lens 43 and shines on the glass plate 32 to form far-field parallel light. In addition, the flash detector is also equipped with a button 10 for controlling the detection module 2 and a display screen 11 for displaying the detection results.

[0057] Industrial cameras, equipped with telecentric lenses, image the object being measured under illumination from telecentric parallel light and a ring light source. The telecentric lens eliminates parallax present in ordinary lenses, ensuring consistent object size at different object distances, thus achieving high-precision measurement. The telecentric parallel light provides uniform, parallel light, reducing shadows and reflections, ensuring uniform illumination of the object's surface, which improves image contrast and clarity. The ring light source illuminates the object from different angles, highlighting its contours and features, further enhancing image quality and facilitating subsequent image analysis and processing. Specifically, software programs analyze the object images captured by the industrial camera, using image processing algorithms to identify the object's edges, contours, and other features. Based on pre-calibrated camera parameters, lens parameters, and light source characteristics, the object's size, shape, and other parameters are calculated. For example, by measuring the pixel distance between object edges in the image and combining this with the camera's resolution and calibration coefficients, the pixel distance is converted into actual physical dimensions, thereby achieving accurate measurement of the object.

[0058] Furthermore, such as Figure 5 and Figure 6 As shown, the four sets of lifting mechanisms 33 are evenly distributed at the four corners of the support 31. Each set of lifting mechanisms 33 includes a base plate 332, a guide cylinder 333 disposed on the base plate 332, a piston 334 slidably disposed in the guide cylinder 333 and coaxially fixed with the push rod a331, a cover plate 335 installed on the end face of the guide cylinder 333, and a spring a336 sleeved on the push rod a331 and abutting against the piston 334 and the base plate 332. The push rod a331 is disposed through the base plate 332 and the cover plate 335.

[0059] Furthermore, such as Figure 5 As shown, the lifting mechanism 33 also includes a guide groove 347 formed on the side wall of the guide cylinder 333 along the length direction of the guide cylinder 333, and a guide rod 348 disposed on the side of the piston 334 and slidably disposed in the guide groove 347.

[0060] It should be noted that the synchronous upward movement of the four sets of top rods a331 can push the glass plate 32 out of the support 31 as a whole, thereby enabling the disassembly of the glass plate 32. Conversely, when the glass plate 32 is placed on the four sets of top rods a331, the downward movement of the top rods a331 will cause the glass plate 32 to move downward into the interior of the support 31. The above-mentioned method of disassembling and assembling the glass plate 32 can effectively reduce bumps and knocks.

[0061] It should also be noted that the guide rod 348, located within the guide groove 347, prevents the top rod a331 from rotating during movement, thereby making the movement of the glass plate 32 more stable.

[0062] Furthermore, such as Figure 4 and Figure 12 As shown, the centering mechanism 34 includes a vertical plate 341 disposed on the mounting platform 1, two sets of circular holes 342 symmetrically opened on the vertical plate 341, a stepped hole 343 coaxially disposed with the circular holes 342 and opened on the side of the vertical plate 341 opposite to the glass plate 32, a push rod 344 correspondingly inserted in the circular holes 342 and capable of abutting against the glass plate 32, a baffle 345 coaxially disposed on the push rod 344, and a spring b346 sleeved on the push rod 344 and located between the baffle 345 and the stepped hole 343.

[0063] It should be noted that the push rod 344 abuts against the edge of the glass plate 32 to achieve the centering of the glass plate 32.

[0064] It should also be noted that, due to the driving action of the pressure plate unit 352, the final moving position of the push rod 344 remains unchanged. Therefore, the effect of the rotation of the push rod 344 during movement on the centering process of the glass plate 32 is negligible.

[0065] Furthermore, such as Figure 3 and Figure 4 As shown, the pressure plate unit 352 includes a movable seat 3521 sleeved above the top rod b351, a mounting seat 3522 mounted on the mounting platform 1 and located in front of the top rod b351, two sets of connecting rods a3523 symmetrically hinged to both sides of the movable seat 3521, two sets of connecting rods b3524 symmetrically hinged to both sides of the movable seat 3521 and located behind the connecting rods a3523, and a mounting plate unit 3522 symmetrically hinged to the mounting plate 3522 with its middle position aligned with the top rod b351. The system includes two sets of connecting rods c3525 hinged to connecting rod a3523, a pressure plate 3526 hinged to the two sets of connecting rods b3524 and c3525 respectively, a linear bearing 3527 mounted on the mounting platform 1 for mounting the top rod b351, and a spring c3528 sleeved on the top rod b351 and connecting the moving seat 3521 and the linear bearing 3527. The connecting rod c3525 is correspondingly abutting against the push rod 344.

[0066] It should be noted that, as Figures 8 to 10As shown, the movement of the top rod b351 drives the movement of the moving seat 3521, which in turn causes the connecting rod a3523, the connecting rod b3524, the connecting rod c3525 and the pressure plate 3526 to swing. The connecting rod c3525 drives the push rod 344 to move. Finally, the connecting rod c3525 stops swinging first, and the push rod 344 moves into place. Then, the connecting rod a3523 and the connecting rod b3524 continue to drive the pressure plate 3526 to swing, and the pressure plate 3526 presses the glass plate 32 from top to bottom.

[0067] Furthermore, the pressure plate 3526 includes a pressure plate body 35261, a pressure piece 35262 disposed at the bottom front side of the pressure plate body 35261 and capable of abutting against the glass plate 32, and an abutting piece 35263 disposed at the bottom rear side of the pressure plate body 35261 and capable of abutting against the top of the top rod b351.

[0068] It should be noted that the pressure plate 35262 is made of nylon, which can effectively prevent the glass plate 32 from being scratched. When the pressure plate 35262 is in contact with the glass plate 32, the top of the push rod b351 is in contact with the contact piece 35263.

[0069] It should also be noted that when the pressure plate 3526 is raised to its maximum height, it completely detaches from the projection coverage of the glass plate 32, thereby ensuring that the glass plate 32 can be installed smoothly.

[0070] Furthermore, such as Figure 7 and Figure 11 As shown, the turntable mechanism 36 includes a turntable unit 361 that is rotatably installed inside the mounting platform 1 and alternately abuts against the top rod a331 and the top rod b351, and a handwheel unit 362 that drives the turntable unit 361 to rotate. The bottom light source 4 generates light that can pass through the turntable unit 361 to illuminate the glass plate 32.

[0071] Furthermore, the turntable unit 361 includes a rotary support bearing 3611 disposed within the mounting platform 1 and below the loading platform 3, a mounting ring 3612 disposed on the rotary support bearing 3611, and a guide block 3613 disposed on the mounting ring 3612 and capable of abutting against the bottom of the top rod a331 and the top rod b351.

[0072] It should be noted that the slewing bearing 3611 is existing technology, and its working principle will not be described in detail here.

[0073] Furthermore, such as Figure 11As shown, the handwheel unit 362 includes a base 3621 mounted on the mounting platform 1, two sets of tapered roller bearings 3622 respectively embedded at the upper and lower ends of the base 3621, bearing caps 3623 mounted at the upper and lower ends of the base 3621 and capable of abutting against the outer rings of the tapered roller bearings 3622, a rotating shaft 3624 passing through the two sets of tapered roller bearings 3622, and a bearing cap 3623 coaxially mounted on the rotating shaft 3624 and connected to the tapered roller bearings 3622 below. The components include an abutment plate 3625 that can abut against the ring, a locking nut 3626 that is threadedly fitted on the rotating shaft 3624 and abuts against the inner ring of the tapered roller bearing 3622 above, a gear 3627 that is coaxially disposed below the rotating shaft 3624 and meshes with the slewing support bearing 3611, a handwheel 3628 disposed at the top of the rotating shaft 3624, and a clamping seat 3629 that is sleeved on the outside of the rotating shaft 3624 and mounted above the bearing cover 3623 above.

[0074] It should be noted that the two sets of tapered roller bearings 3622 can improve the rotational rigidity of the shaft 3624.

[0075] It should be further noted that rotating the handwheel 3628 drives the rotating shaft 3624 to rotate, which in turn drives the gear 3627 to drive the rotation, which in turn drives the slewing support bearing 3611 to rotate. After the handwheel 3628 is rotated to the position, the rotating shaft 3624 is fixed by the clamping seat 3629.

[0076] Work process:

[0077] The process of disassembling the glass plate: Loosen the clamping seat 3629, then rotate the handwheel 3628 so that the gear 3627 drives the slewing support bearing 3611 to rotate. The guide block 3613 disengages from the push rod b351. The push rod b351 moves down and drives the moving seat 3521 to move down. The connecting rod a3523 and connecting rod b3524 drive the pressure plate 3526 to move. The pressure plate 35262 disengages from the glass plate 32. Then the connecting rod... C3525 rotates, causing the push rod 344 to disengage from the side wall of the glass plate 32. Then, the guide block 3613 abuts against the top rod a331, and the top rod a331 abuts against the bottom of the glass plate 32. The four sets of top rods a331 move synchronously to push the glass plate 32 out of the support seat 31. Then, the clamping seat 3629 is clamped to fix the gear 3627 and the rotary support bearing 3611. After that, the worker can easily remove the glass plate 32.

[0078] The glass plate installation process: The guide block 3613 and the top rod a331 lift the glass plate 32. The worker places the glass plate 32 on top of the four sets of lifting top rods a331. Then, the clamping seat 3629 is released, and the handwheel 3628 is rotated so that the gear 3627 drives the slewing support bearing 3611 to rotate. The guide block 3613 disengages from the top rod a331, and the glass plate 32 is placed stably in the support seat 31. Then, the guide block 3613 abuts against the top rod b351, and the top rod b351 and the moving seat 3521 move upward, thereby driving the glass plate 32 to move upward. The connecting rods a3523, b3524, c3525, and pressure plate 3526 swing. The connecting rod c3525 drives the push rod 344 to move. The connecting rod c3525 stops swinging first, and the push rod 344 moves into place to complete the centering of the glass plate 32. Then, the connecting rods a3523 and b3524 continue to drive the pressure plate 3526 to move. Finally, the pressure plate 35262 presses the glass plate 32, and the top of the top rod b351 abuts against the contact piece 35263. Then, the clamping seat 3629 is clamped to complete the fixation.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
