Description

Technical Field

[0001] This invention relates to the field of optical component processing technology, specifically to a mirror flipping fixture for batch operations. Background Technology

[0002] In the field of optical component processing, situations often require the flipping of mirrors. If the mirror is large and heavy, simply flipping it by hand is prone to accidents such as bumps and drops. Mirrors are expensive and have long processing cycles; damage can significantly impact project costs and timelines. Therefore, it is necessary to develop a mirror flipping fixture capable of accurately flipping mirrors. Currently common mirror flipping fixtures have simple structures and cannot effectively handle potential stalls and sudden stops during the flipping process. Stalls and sudden stops can cause impacts and vibrations, potentially damaging the mirror. Furthermore, current common mirror flipping fixtures require the mirror to be mounted on a clamp, and a crane to lift the clamp and mirror onto the fixture. Then, the operator tightens screws to install the clamp and mirror onto the fixture before flipping. After flipping, the operator loosens the screws, and the crane removes the clamp and mirror. The entire process is cumbersome, time-consuming, and risky. Summary of the Invention

[0067] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0068] In the exemplary technology, the mirror flipping fixture requires the mirror to be mounted on a clamp during operation. A crane then lifts the clamp and mirror onto the flipping fixture. An operator tightens the screws to secure the clamp and mirror to the fixture before flipping can begin. After flipping, the operator loosens the screws and uses the crane to remove the clamp and mirror. The entire process is cumbersome, time-consuming, and risky.

[0069] This application provides a mirror flipping fixture for batch operations, which solves the technical problems of cumbersome operation, long time and high risk in the flipping process of large and heavy mirrors in the prior art.

[0070] This application provides an optional embodiment, referring to... Figures 1-6 As shown, the mirror flipping fixture for batch operations includes a mirror loading cart 1 and a flipping fixture 2. The mirror loading cart 1 includes a loading cart 11, a mirror loading tray 12, a clamp 14, and a limiting fixture. The flipping fixture 2 includes a flipping frame 21, a limiting component 22, a clamping and flipping component 24, a drive component 23, and a damping component 25. The mirror loading tray 12 is mounted on the loading cart 11. The clamp 14 is mounted on the mirror loading tray 12. The limiting component 22 is mounted on the flipping frame 21. The clamping and flipping component 24 is mounted on the flipping frame 21. The drive component 23 is connected to the clamping and flipping component 24. The damping component 25 is mounted on the flipping frame 21.

[0071] The reflector loading tray 12 holds the reflector in place. A clamp 14 holds the reflector on the reflector loading tray 12. A limiting fixture is mounted on the loading vehicle 11 to limit the position of the reflector loading tray 12. The tilting frame 21 has a fixed position for the reflector loading vehicle 1 to be inserted. The limiting component 22 fixes the planar position of the reflector loading vehicle 1 when it is inserted. The clamping and tilting component 24 clamps the reflector and tilts it. A driving component 23 drives the clamping and tilting component 24 to move along a first direction. A damping component 25 prevents the accelerating movement of the clamping and tilting component 24.

[0072] The above solution enables the flipping of large and heavy mirrors using the flipping fixture 2 and the mirror loading vehicle 1, without the need for hoisting. This solves the technical problems of cumbersome operation, long time, and high risk in the flipping of large and heavy mirrors in the prior art.

[0073] Optionally, the first direction generally refers to the height direction. In special workpieces, it can also be the horizontal direction or other directions, which can be set according to the actual needs of use.

[0074] In one alternative embodiment, the limiting fixture includes multiple limiting posts 15, which are located between the reflector loading plate 12 and the loading vehicle 11. The reflector loading plate 12 is provided with positioning holes corresponding to the number of limiting posts 15, and each limiting post 15 is snapped into the corresponding positioning hole when the reflector loading plate 12 is installed.

[0075] The number of limiting posts 15 can be set as needed, for example, three, which are fixed on the loading vehicle 11 to position the reflector loading plate 12, thereby positioning the reflector 13.

[0076] In one alternative embodiment, the mirror loading disk 12 is provided with a positioning inclined surface and a positioning pin hole. The positioning inclined surface is provided on the clamping part of the mirror loading disk 12, and the positioning pin hole is provided on the outer circular surface of the clamping part of the mirror loading disk 12.

[0077] The locating bevel facilitates the clamping and flipping assembly 24 to clamp the reflector loading tray 12. The locating pin hole positions the relative position between the clamping and flipping assembly 24 and the reflector loading tray 12.

[0078] Optionally, both sides of the reflector loading disk 12 are provided with positioning ramps and positioning pin holes.

[0079] Optionally, the limiting component 22 can be implemented in the form of a limiting block, which has a V-shaped opening structure. This can limit the position of the reflector loading vehicle 1 in the left-right and front-back directions.

[0080] In one alternative approach, refer to Figure 7 As shown, the drive assembly 23 includes a first drive member, a second drive member, a transmission member, a ratchet mechanism 238, and a hand crank mechanism 239. The first drive member and the second drive member are arranged opposite to each other and are connected by transmission through the transmission member. The ratchet mechanism 238 and the hand crank mechanism 239 are mounted on the second drive member.

[0081] In one alternative embodiment, the transmission component includes a transmission shaft 232, and the first driving component or the second driving component includes multiple support seats 231, multiple transmission shafts 232, multiple pulleys 233, multiple drive plates 234, multiple synchronous belts 235 and multiple bevel gears 236. The multiple support seats 231 are disposed on the tilting frame 21, and each transmission shaft 232 is disposed on the tilting frame 21 through the support seat 231.

[0082] In the first or second drive unit, two drive shafts 232 are arranged opposite to each other, and each drive shaft 232 is provided with an equal number of pulleys 233 in opposite positions. A timing belt 235 is sleeved on the opposite pulleys 233. A drive plate 234 is sleeved on each timing belt 235.

[0083] In a horizontal plane, the drive shaft 232 of the first drive member is connected to one end of the drive shaft 232 of the transmission member via a bevel gear 236, and the other end of the drive shaft 232 of the transmission member is connected to the drive shaft 232 of the second drive member via another bevel gear 236.

[0084] In the above embodiment, the pulley 233 and the synchronous belt 235 cooperate to convert rotational motion into linear lifting motion. The drive plate 234 fixes the synchronous belt 235 and the clamping and tilting assembly 24 together, driving the clamping and tilting assembly 24 to rise and fall with the synchronous belt 235. The synchronous belt 235 and the pulley 233 cooperate to convert rotational motion into linear lifting motion. The bevel gear 236 transmits torque at a 90° angle at the corner of the drive shaft 232, ensuring that the synchronous belts 235 on both sides rise and fall synchronously.

[0085] Optionally, there are 5 drive shafts 232, 8 pulleys 233, 4 drive plates 234, and 4 bevel gears 236.

[0086] In one alternative approach, refer to Figure 8As shown, the ratchet mechanism includes a ratchet 2381, a pawl 2382, a shaft 2383, and a first fixed plate 2384. The ratchet 2381 is fixed on the transmission shaft 232 of the second drive member. The pawl 2382 is snap-fitted to the ratchet 2381. The first fixed plate 2384 is disposed on the tilting frame 21. The shaft 2383 is fixed on the first fixed plate 2384. The pawl 2382 is sleeved on the shaft 2383 and can rotate around the shaft 2383. When the pawl 2382 engages the ratchet 2381, the transmission shaft 232 containing the ratchet 2381 cannot rotate counterclockwise, so that the reflector loading tray remains at its current position in the lifting direction.

[0087] The ratchet mechanism 238 is used to fix the position of the drive assembly 23 during the lifting and lowering process. When the pawl 2382 engages the ratchet 2381, the drive shaft 232 cannot rotate, and the synchronous belt 235 is fixed in position, thereby fixing the position of the clamping and flipping assembly 24 in the lifting and lowering direction. When transmission is required, the pawl 2382 and the ratchet 2381 can be released.

[0088] In one alternative approach, refer to Figure 9 As shown, the hand-cranked mechanism includes a first support base 231, a worm gear 2391, a worm wheel 2392, and a handwheel 2393. The first support base 231 is mounted on the tilting frame 21. The worm wheel 2392 is fixedly connected to the transmission shaft 232 of the second drive component. The worm gear 2391 meshes with the worm wheel 2392. The handwheel 2393 is fixedly connected to the worm gear 2391.

[0089] When the handwheel 2393 rotates, it drives the worm gear 2391 to rotate, which in turn drives the worm wheel 2392 to rotate, thereby driving the transmission shaft 232 of the second driving component to rotate.

[0090] In one alternative approach, refer to Figure 16 As shown, the damping assembly 25 includes: a second fixed plate 251, a second support base 252, a first damper 253, a damping drive shaft 254, a bearing housing 255, a synchronous belt 256, a first damping pulley 257, and a second damping pulley 237.

[0091] The second fixed plate 251 is fixedly connected to the tilting frame 21, the second support base 252 is fixedly connected to the second fixed plate 251, the first damper 253 is disposed on the second support base 252, the damping drive shaft 254 is fixedly connected to the output shaft of the first damper 253, the first damping pulley 257 is fixedly connected to the damping drive shaft 254, the synchronous belt 256 is sleeved on the first damping pulley 257 and the second damping pulley 237, and the second damping pulley 237 is disposed on the drive shaft 232 of the first drive member or the drive shaft 232 of the second drive member.

[0092] The synchronous belt 256 transmits the damping generated by the first damper 253 to the second damping pulley 237. The second damping pulley 237 is connected to the damping assembly 25 to provide damping for the drive assembly 23, ensuring uniform and stable lifting and preventing stalling and sudden stops.

[0093] Optionally, the second damper 2467 is fixedly connected to the telescopic plate 2466, and its output shaft is connected to the connector 2463, so that the telescopic shaft 2461 is damped when it rotates, ensuring uniform and stable rotation process and preventing stalling and sudden stop.

[0094] In one alternative approach, refer to Figure 10 As shown, the clamping and flipping assembly 24 includes a linear guide assembly 241, a flipping fixture 242, a first connecting pin 243, multiple support blocks 244, multiple locking mechanisms 245, multiple telescopic shaft mechanisms 246, and multiple positioning pins 247. The linear guide assembly 241 is fixedly connected to the flipping frame 21. The support blocks 244 are sleeved on the linear guide assembly 241, and the locking mechanisms 245 are disposed through the support blocks 244. The first connecting pin 243 connects the telescopic shaft mechanisms 246 and the flipping fixture 242.

[0095] The linear guide assembly 241 provides lifting and guiding functions for the clamping and flipping assembly 24. The flipping clamp 242 clamps the reflector loading tray 12, and the first connecting pin 243 connects the telescopic shaft 2461 and the flipping clamp 242. The support block 244 is used to support other parts inside the clamping and flipping assembly 24. The locking mechanism 245 locks the flipping clamp 242 before and after the clamping and flipping assembly 24 is flipped, so that it will not rotate arbitrarily during the lifting and lowering process, ensuring stability and reliability.

[0096] In one alternative approach, refer to Figure 11 As shown, the linear guide assembly includes a bearing seat 2411, a linear bearing 2412, and a guide shaft 2413. The bearing seat 2411 is fixed on the tilting frame 21, the guide shaft 2413 is fixed on the bearing seat 2411, the linear bearing 2412 passes through the guide shaft 2413 and is fixedly connected to the support block 244, and the linear bearing 2412 moves along the extension direction of the guide shaft 2413.

[0097] The linear bearing 2412 can slide along the guide shaft 2413 and is fixedly connected to the support block 244, so that the linear guide assembly 241 provides lifting and lowering guidance for the clamping and flipping assembly 24.

[0098] In one alternative embodiment, the locking mechanism includes a locking shaft 2451, a spring 2452, a spring pin 2453, and a handle 2454. The spring 2452 passes through the support block 244 and is wound around the locking shaft 2451. The spring pin 2453 is located on the locking shaft 2451 and abuts against the spring 2452. The handle 2454 is fixedly connected to the locking shaft 2451.

[0099] When the handle 2454 is extended or pulled back, adjust and flip the position of the clamp to achieve locking.

[0100] In one alternative approach, refer to Figure 13 , 14 As shown in Figure 15, the telescopic shaft mechanism includes a telescopic shaft 2461, multiple sliding columns 2462, a connector 2463, a second connecting pin 2464, a flange 2465, a telescopic plate 2466, a second damper 2467, multiple retaining rings 2468, and multiple expansion sleeves 2469. The front end of the telescopic shaft 2461 is connected to the flipping clamp 242 through the first connecting pin 243. The middle section of the telescopic shaft 2461 passes through the hole of the support block 244 and can rotate and slide within the hole. The tail end of the telescopic shaft 2461 is connected to the connector 2463 through the second connecting pin 2464. The flange 2465 is fixedly connected to the telescopic plate 2466, which locks the connector 2463 so that the connector 2463 can rotate within the flange 2465 and can slide back and forth with the flange 2465 and the telescopic plate 2466.

[0101] The sliding column 2462 is fixedly connected to the support block 244. The telescopic plate 2466 can slide on the sliding column 2462. The expansion sleeve 2469 is threadedly connected to the telescopic plate 2466 and has a clearance fit with the hole shaft of the sliding column 2462. The second damper 2467 is fixedly connected to the telescopic plate 2466, and its output shaft is connected to the connector 2463, so that the telescopic shaft 2461 is damped when it rotates, so as to maintain a uniform and stable rotation process.

[0102] When it is necessary to fix the position of the telescopic plate 2466, tighten the expansion sleeve 2469 to lock the slide column 2462. The retaining ring 2468 is threadedly connected to the slide column 2462 to prevent the telescopic plate 2466 from falling off the slide column 2462.

[0103] The following describes the working process of the mirror flipping fixture, which consists of a mirror loading vehicle 1 and a flipping fixture 2, and is designed for batch operations:

[0104] First step, refer to Figure 17 As shown, the reflector loading vehicle 1 with reflector 13 is pushed into the tilting fixture 2, and the reflector loading vehicle 1 is limited by the limiting block 22 of the loading vehicle 11. Then the casters on the reflector loading vehicle 1 are locked.

[0105] Step 2, refer to Figure 18, 19 As shown in Figure 20, the ratchet mechanism 238 is released, and the handwheel 2393 is cranked to drive the worm gear 2391 and worm wheel 2392, thereby driving the transmission shaft 232 and the synchronous belt 235, which in turn drive the tilting clamp 242, the first connecting pin 243, the support block 244, the locking mechanism 245, and the telescopic shaft mechanism 246 to descend. The tilting clamp 242 stops when it descends to the clamping position. At this time, the four expansion sleeves 2469 are released, the tilting clamp 242 is pushed out, and the parts connected to the tilting clamp 242 slide forward on the slide column 2462 accordingly. The inclined groove of the tilting clamp 242 engages the positioning inclined surface of the reflector loading plate 12, and the positioning pin 247 on the tilting clamp 242 is inserted into the positioning pin hole on the outer circle of the reflector loading plate 12. Then, push the handle 2454 forward so that the locking shaft 2451 is inserted into the groove in the flipping fixture 242. The handle 2454 is locked onto the support block 244. One end of the spring 2452 supports the locking shaft 2451, and the other end supports the groove on the support block 244, ensuring that the locking shaft 2451 will not loosen. Finally, tighten the four expansion sleeves 2469 again to prevent the fixture 14 from moving.

[0106] Third step, refer to Figure 21 As shown, cranking the handwheel 2393 raises the reflector 13 to a certain height. During the ascent, the damping component 25 provides damping to ensure a uniform and stable ascent, preventing stalling and sudden stops. After reaching the designated height, the ratchet mechanism 238 engages the drive shaft 232, fixing the position of the reflector 13 in the lifting direction.

[0107] Step 4, refer to Figure 22 , 23 As shown, pull the handle 2454 backward so that the spring pin 2453 protrudes from the hole of the support block 244. The spring pin 2453 pops out and locks the support block 244, preventing the locking shaft 2451 from extending. At this time, the locking mechanism 245 has no locking effect on the flipping fixture 242.

[0108] Step 5, refer to Figure 24 As shown, the manually rotated rotating fixture 242 rotates the reflector 13 180 degrees. During the rotation process, the second damper 2467 provides damping to ensure a uniform and stable rotation process and prevent stalling and sudden stops.

[0109] Step 6, refer to Figure 25 As shown, use a tool to press the popped-out spring pin 2453 back in, push the handle 2454 to extend the locking shaft 2451, and re-lock the flipping clamp 242.

[0110] Step 7, refer to Figure 26As shown, release the ratchet mechanism 238 and crank the handwheel 2393 to lower the reflector 13 until the inclined surface on the outer circle of the reflector loading plate 12 falls onto the limiting post 15. At this point, the reflector 13 has achieved a 180-degree rotation.

[0111] Step 8, refer to Figure 27 As shown, move the two flipping clamps 242 backward to release the reflector loading tray 12. Then raise the flipping clamps 242 so that the reflector 13 can be pulled out using the reflector loading cart 1.

[0112] The above-mentioned mirror flipping fixture, designed for batch operations, is stable and reliable, and can effectively flip large-weight and large-size mirrors, making the flipping process more convenient, faster, and safer.

[0113] Based on the above description, this patent provides a mirror flipping fixture for batch operations, which solves the problems of cumbersome operation, long time and high risk in the operation of common flipping fixtures. The entire flipping process does not require a crane, there is no lifting process, and no screw tightening. It is more convenient, faster and safer, and effectively deals with the phenomenon of stalling and sudden stop that may occur during the flipping process.

[0114] like Figure 1 -- Figure 14As shown, this invention relates to a mirror flipping fixture for batch operations. A mirror loading tray 12 is used to load mirrors 13, and has positioning ramps and positioning pin holes on both sides for easy clamping and positioning by the fixture on the flipping fixture 2. A fixture 14 clamps the mirror 13 onto the mirror loading tray 12. Three limiting posts 15 are fixed to the loading cart 11 to position the mirror loading tray 12, thereby positioning the mirror 13. The flipping frame 21 can move and be positioned freely. The loading cart limiting block 22 adopts a V-shaped opening structure to limit the left-right and front-back positions of the mirror loading cart 1. Twelve support seats 231 support the entire drive assembly 23 and are fixed to the flipping frame 21. Five drive shafts 232 connect pulleys 233, bevel gears 236, damping pulleys 237, ratchet mechanisms 238, and hand crank mechanisms 239 to transmit motion. There are eight pulleys 233, fixed on the drive shaft 232, which cooperate with the synchronous belt 235 to convert rotational motion into linear lifting motion. Four drive plates 234 connect the synchronous belt 235 and the clamping and tilting assembly 24, driving the clamping and tilting assembly 24 to rise and fall with the synchronous belt 235. Four synchronous belts 235 cooperate with the pulleys 233 to convert rotational motion into linear lifting motion. Four bevel gears 236 transmit torque at a 90° angle at the corners of the drive shaft 232, ensuring synchronous lifting and lowering of the synchronous belts 235 on both sides. Damping pulleys 237 are connected to the damping assembly 25, providing damping to the drive assembly 23 to ensure uniform and stable lifting and lowering, preventing stalling and sudden stops. The ratchet mechanism 238 is used to fix the position of the drive assembly 23 during lifting and lowering. When the pawl 2382 engages the ratchet 2381, the drive shaft 232 cannot rotate counterclockwise, and the synchronous belt 235 is fixed in position, thus fixing the position of the clamping and tilting assembly 24 in the lifting and lowering direction. When transmission is needed, the pawl 2382 and ratchet 2381 can be released. The handwheel 2393 is fixedly connected to the worm gear 2391, and can be manually rotated to drive the worm gear 2391 to rotate. The worm gear 2391 meshes with the worm wheel 2392, and the worm wheel 2392 is fixedly connected to the drive shaft 232. When the worm gear 2391 rotates, it drives the worm wheel 2392 to rotate, thereby driving the drive shaft 232 to rotate. The linear bearing 2412 can slide along the guide shaft 2413 and is fixedly connected to the support block 244, thus the linear guide assembly 241 provides lifting and lowering guidance for the clamping and tilting assembly 24. The flipping clamp 242 holds the reflector loading tray 12. The first connecting pin 243 connects the telescopic shaft 2461 and the flipping clamp 242. The support block 244 is used to support other parts inside the flipping assembly 24. The locking mechanism 245 locks the flipping clamp 242 before and after the flipping assembly 24 is flipped, so that it will not rotate arbitrarily during the lifting and lowering process, ensuring stability and reliability.The front end of the telescopic shaft 2461 is connected to the flipping clamp 242 via the first connecting pin 243. The middle section mates with the hole in the support block 244, allowing it to rotate and slide within the hole. The rear end is connected to the connector 2463 via the second connecting pin 2464. The flange 2465 is fixedly connected to the telescopic plate 2466, securing the connector 2463. The connector 2463 can rotate within the flange 2465 and slide back and forth with both the flange 2465 and the telescopic plate 2466. The flange 2465 is fixedly connected to the telescopic plate 2466. There are four sliding columns 2462, all fixedly connected to the support block 244. The telescopic plate 2466 can slide on the sliding columns 2462. The expansion sleeve 2469 is threadedly connected to the telescopic plate 2466 and has a clearance fit with the hole in the sliding column 2462. When it is necessary to fix the position of the telescopic plate 2466, tighten the expansion sleeve 2469 to lock the sliding column 2462. The retaining ring 2468 is threadedly connected to the sliding column 2462 to prevent the telescopic plate 2466 from falling off the sliding column 2462. The second damper 2467 is fixedly connected to the telescopic plate 2466, and its output shaft is connected to the connector 2463, so that the telescopic shaft 2461 is damped when rotating, ensuring uniform and stable speed during the tilting process and preventing stalling and sudden stops. The damping pulley 237 is fixed on the drive shaft 232, and the synchronous belt 256 transmits the damping from the damping assembly 25 to the damping pulley 237, providing damping for the drive assembly 23, ensuring uniform and stable speed during the lifting process, and preventing stalling and sudden stops.

[0115] Based on the above description, this patent provides a mirror flipping fixture for batch operations, which solves the problems of cumbersome operation, long time and high risk in the operation of common flipping fixtures. The entire flipping process does not require a crane, there is no lifting process, and no screw tightening. It is more convenient, faster and safer, and effectively deals with the phenomenon of stalling and sudden stop that may occur during the flipping process.
