Description

Technical Field

[0001] This utility model relates to the field of optical glass coating technology, specifically to an optical glass coating fixture with adjustment function. Background Technology

[0002] Optical glass is a type of glass material used to manufacture lenses, prisms, mirrors, windows, etc., for optical instruments or mechanical systems. It includes colorless optical glass, colored optical glass, radiation-resistant optical glass, radiation-proof glass, and optical quartz glass. Before installation and use, the surface of optical glass needs to be coated for protection to reduce the possibility of scratches.

[0003] Publication No. CN220846256U discloses an optical glass coating fixture. This device uses a servo motor to drive two lifting frames to move closer together. The two lifting frames move closer together, causing two clamping plates to clamp and fix the optical glass on the upper surface of the placement platform. The servo motor drives the mounting plate and the clamping plates holding the optical glass to move upwards. The servo motor also drives a worm gear and a worm wheel to rotate. The rotation of the worm wheel causes the clamping plates and the optical glass to flip. Simultaneously, the locking characteristics of the worm gear and worm wheel allow the optical glass to remain stably on the other side. This solves the problem of existing devices requiring manual flipping and re-clamping when coating the other side of the optical glass, and the easy scratching of the bottom of the optical glass during handling and clamping. However, this patent still has the following problems in practical use:

[0004] The device uses a servo motor to drive two lifting frames to move closer together. The two lifting frames move closer together, causing two clamping plates to clamp and fix the optical glass on the upper surface of the platform. However, when the device clamps and coats disc-shaped optical glass, there are usually only two points of contact between the clamping plates and the disc-shaped optical glass. This contact method cannot provide a uniform distribution of clamping force. Due to the few contact points, the clamping force is easily concentrated on a few points, which may cause the disc-shaped optical glass to shift or shake during the clamping process, affecting the accuracy and quality of the coating and posing limitations for operators.

[0005] An optical glass coating fixture with adjustment function is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an optical glass coating fixture with an adjustable function to solve the problem mentioned in the background art. Currently, the device uses a servo motor to drive two lifting frames to move closer together, which in turn drives two clamping plates to clamp and fix the optical glass on the upper surface of the platform. However, when this device clamps and coats disc-shaped optical glass, there are usually only two points of contact between the clamping plates and the disc-shaped optical glass. This contact method cannot provide a uniform distribution of clamping force. Due to the small number of contact points, the clamping force is easily concentrated on a few points, which may cause the disc-shaped optical glass to shift or shake during the clamping process, affecting the accuracy and quality of the coating.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an optical glass coating fixture with adjustable function, comprising a clamping frame, support plates symmetrically arranged on both sides of the clamping frame, and a worktable fixedly installed between the bottoms of the support plates; a clamping mechanism is provided between the clamping frame and the support plates, and a collecting component is provided on the top of the worktable;

Electric telescopic rods are symmetrically fixedly installed on the outside of the clamping frame. A connecting plate is fixedly connected to the end of the movable plate away from the clamping frame. The output end of the electric telescopic rod is fixedly connected to the connecting plate. A rotating shaft is rotatably connected inside one end of the movable plate. A fixing block is fixedly installed on the top outer side of the rotating shaft. A pressing plate is fixedly installed on one side of the fixing block. An arc-shaped plate is fixedly installed on the side of the fixing block away from the pressing plate. A limit box is fixedly installed on one side of the bottom of the movable plate. The bottom of the rotating shaft passes through the limit box and is rotatably connected to the limit box.

[0009] Preferably, a sliding rod is slidably connected to one end of the limiting box, and a sliding plate is fixedly installed at one end of the sliding rod. An insert plate is fixedly installed on the side of the sliding plate away from the sliding rod. Slots are symmetrically opened on the outer side of the bottom of the rotating shaft, and the insert plate is inserted into the slot. A fixing tube is symmetrically fixedly connected to one side of the inside of the limiting box. A pressing rod is symmetrically fixedly installed on the side of the sliding plate close to the sliding rod. One end of the pressing rod passes through the fixing tube and is slidably connected to the fixing tube. A first contraction spring is provided inside the fixing tube.

[0010] Preferably, the clamping frame is symmetrically fixedly connected to the two sides of the clamping frame, and a fixed shaft is fixedly connected to the side of the support frame away from the clamping frame. One end of the fixed shaft passes through the support plate and is rotatably connected to the support plate. A large sprocket is fixedly installed on the outside of one end of the fixed shaft. A rotating rod is rotatably connected to one side of the support plate. A small sprocket is fixedly installed on the outside of the rotating rod. A servo motor is fixedly installed on one end of the rotating rod. A chain is meshed between the outside of the large sprocket and the small sprocket.

[0011] Preferably, the collecting component includes a collecting frame disposed on the top of the workbench, and a positioning box is embedded in the lower interior of the support plate. The collecting frame has symmetrical positioning slots on both sides. A threaded tube is fixedly connected inside the positioning box, and a threaded rod is threadedly connected inside the threaded tube. A push plate is rotatably connected to one end of the threaded rod. A positioning block is welded to one side of the push plate, and the positioning block is inserted into the positioning slot.

[0012] Preferably, a retractable rod is symmetrically fixedly installed between the outside of the clamping frame and the connecting plate, and a second retractable spring is sleeved on the outside of the retractable rod.

[0013] Preferably, a rubber pad is embedded on one side of both the extrusion plate and the arc plate.

[0014] Preferably, the bottom side of the servo motor is fixedly connected to the support plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: An optical glass coating fixture with an adjustable function is described below: The operation of an electric telescopic rod drives four moving plates to move inside the clamping frame. The movement of the moving plates causes four arc-shaped plates to clamp the disc-shaped optical glass. The operator can rotate the shaft inside the moving plates, at which point the four pressing plates correspond to clamp the rectangular optical glass. This enables rapid clamping and fixing of optical glass of various specifications, avoiding uneven clamping force that could cause indentations or scratches on the optical glass surface. Especially during clamping and flipping processes, this greatly improves the flexibility of optical glass coating and enhances efficiency. The high efficiency of optical glass coating is achieved through the cooperation between the insert plate and the slot, which enables rapid fixation and limiting of the rotating shaft. This facilitates the positioning of the extrusion plate and the curved plate when switching between them, preventing loosening when the extrusion plate or the curved plate clamps the optical glass and improving the stability of the optical glass coating process. By rotating two sets of threaded rods inside the threaded tube, the rotation of the threaded rods causes the push plate to slide inside the positioning box. At this time, multiple sets of positioning blocks are inserted into the positioning slots, which enables the rapid installation and disassembly of the collection frame. The collection frame facilitates the collection of dripping coating liquid, making it convenient for workers to recycle the residue later.

[0016] 1. The operation of the electric telescopic rod drives four movable plates to move inside the clamping frame. The movement of the movable plates causes four arc-shaped plates to clamp the disc-shaped optical glass. When the operator needs to clamp rectangular optical glass, the operator can rotate the shaft inside the movable plate. When the shaft rotates the fixed block 180 degrees, the four pressing plates align accordingly, clamping the rectangular optical glass. This enables the rapid clamping and fixing of optical glass of various specifications, avoiding uneven clamping force that could cause indentations or scratches on the optical glass surface. Especially during clamping and flipping, this greatly improves the flexibility and efficiency of optical glass coating. After the shaft angle is adjusted, the operator pulls the slide bar to slide inside the limiting box. The movement of the slide bar causes the sliding plate to slide inside the limiting box. The movement of the sliding plate causes the two sets of pressing rods to slide inside the fixed tube. At this time, the first compression spring is compressed. The process involves retracting the slide bar, then releasing it via a worker. The tension generated by the first retraction spring allows the insert plate to engage with the slot, quickly fixing and limiting the rotating shaft. This facilitates positioning when switching between the extrusion plate and the curved plate, preventing loosening during subsequent clamping of the optical glass and improving stability during coating. A servo motor, driven by a controller operated by the worker, rotates a rotating rod, which in turn rotates a small sprocket. The interaction between the large sprocket, small sprocket, and chain causes the fixed shaft to rotate inside the support plate. This rotation, in turn, rotates the support frame, which in turn flips the clamping frame. This allows for quick adjustment and flipping of the optical glass, facilitating coating on both sides and further enhancing flexibility during coating.

[0017] 2. The worker places the collection frame on top of the workbench. At this time, the worker rotates two sets of threaded rods inside the threaded tube. The rotation of the threaded rods causes the push plate to slide inside the positioning box. At this time, multiple sets of positioning blocks are inserted into the positioning slots, thereby achieving the effect of quick installation and disassembly of the collection frame. The collection frame makes it easy for workers to collect the dripping coating liquid, which is convenient for workers to recycle the residue later. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides a technical solution: an optical glass coating fixture with an adjustable function, including a clamping frame 1, support plates 101 symmetrically arranged on both sides of the clamping frame 1, and a worktable 102 fixedly installed between the bottoms of the support plates 101; a clamping mechanism 2 is provided between the clamping frame 1 and the support plates 101, and a collecting component 3 is provided on the top of the worktable 102.

[0027] The clamping mechanism 2 includes a movable plate 201, which is disposed inside the clamping frame 1 and slidably connected to it. Electric telescopic rods 202 are symmetrically fixedly installed on the outside of the clamping frame 1. A connecting plate 203 is fixedly connected to the end of the movable plate 201 away from the clamping frame 1, and the output end of the electric telescopic rod 202 is fixedly connected to the connecting plate 203. A rotating shaft 204 is rotatably connected inside one end of the movable plate 201, and a fixing block 205 is fixedly installed on the top outer side of the rotating shaft 204. A fixing block 205 is fixedly installed on one side of the fixing block 205. An extrusion plate 206 is used, and an arc-shaped plate 207 is fixedly installed on the side of the fixing block 205 away from the extrusion plate 206. A limit box 208 is fixedly installed on the bottom side of the moving plate 201, and the bottom of the rotating shaft 204 passes through the limit box 208 and is rotatably connected to the limit box 208. This enables the rapid clamping and fixing of optical glass of various specifications, avoiding uneven clamping force that could cause indentations or scratches on the surface of the optical glass. Especially during clamping and flipping, this greatly improves the flexibility of optical glass coating and increases the efficiency of optical glass coating.

[0028] A sliding rod 209 is slidably connected to one end of the limiting box 208, and a sliding plate 210 is fixedly installed at one end of the sliding rod 209. An insert plate 211 is fixedly installed on the side of the sliding plate 210 away from the sliding rod 209. Slots 212 are symmetrically opened on the outer bottom of the rotating shaft 204, and the insert plate 211 is inserted into the slot 212. A fixing tube 213 is symmetrically fixedly connected to one side of the inside of the limiting box 208. A pressing rod 214 is symmetrically fixedly installed on the side of the sliding plate 210 near the sliding rod 209. One end of the pressing rod 214 passes through the fixing tube 213 and is slidably connected to the fixing tube 213. A first contraction spring 215 is provided inside the fixing tube 213, which can quickly fix and limit the rotating shaft 204. This facilitates the positioning of the pressing plate 206 and the arc plate 207 when the operator switches them, and prevents the pressing plate 206 or the arc plate 207 from loosening when clamping the optical glass, thereby improving the stability of the optical glass during coating.

[0029] Support frames 216 are symmetrically fixedly connected to both sides of the clamping frame 1. A fixed shaft 217 is fixedly connected to the side of the support frame 216 away from the clamping frame 1. One end of the fixed shaft 217 passes through the support plate 101 and is rotatably connected to the support plate 101. A large sprocket 218 is fixedly mounted on the outside of one end of the fixed shaft 217. A rotating rod 219 is rotatably connected to one side of the support plate 101. A small sprocket 220 is fixedly mounted on the outside of the rotating rod 219. A servo motor 221 is fixedly mounted on one end of the rotating rod 219. The bottom side of the servo motor 221 is fixedly connected to the support plate 101. A chain 222 meshes between the outside of the large sprocket 218 and the small sprocket 220. Through the cooperation between the large sprocket 218, the small sprocket 220, and the chain 222, the fixed shaft 217 is driven to rotate inside the support plate 101. The rotation of the fixed shaft 217 drives the rotation of the fixed shaft 217. The rotation of the moving support frame 216 causes the clamping frame 1 to flip, thereby enabling rapid adjustment and flipping of the optical glass. This facilitates the coating of both sides of the optical glass by the staff, further improving the flexibility of the optical glass coating process. A retraction rod 223 is symmetrically fixedly installed between the clamping frame 1 and the connecting plate 203, and a second retraction spring 224 is sleeved on the outside of the retraction rod 223. Through the cooperation between the retraction rod 223 and the second retraction spring 224, the connecting plate 203 can be buffered during movement, improving the stability of the moving plate 201. Rubber pads 225 are embedded on one side of the extrusion plate 206 and the arc plate 207. The design of the rubber pads 225 effectively avoids the phenomenon of rigid extrusion of the optical glass by the extrusion plate 206 and the arc plate 207.

[0030] The collection component 3 includes a collection frame 301 set on the top of the workbench 102, and a positioning box 302 is embedded in the lower interior of the support plate 101. Positioning grooves 303 are symmetrically opened on both sides of the collection frame 301. A threaded tube 304 is fixedly connected inside the positioning box 302, and a threaded rod 305 is threadedly connected inside the threaded tube 304. A push plate 306 is rotatably connected to one end of the threaded rod 305. A positioning block 307 is welded to one side of the push plate 306, and the positioning block 307 is inserted into the positioning groove 303. This allows for quick installation and disassembly of the collection frame 301. The collection frame 301 facilitates the collection of dripping coating liquid by the staff, making it convenient for the staff to recycle the residue later.

[0031] Working principle: Before using this adjustable optical glass coating fixture, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, the operator places the optical glass inside the clamping frame 1. The operator then operates the controller to drive four electric telescopic rods 202. The movement of the electric telescopic rods 202 causes four moving plates 201 to move inside the clamping frame 1. The moving plates 201 move along a convergence-expansion trajectory. The movement of the moving plates 201 causes four arc-shaped plates 207 to clamp the disc-shaped optical glass. When the operator needs to clamp rectangular optical glass, the operator can rotate the rotating shaft 204 inside the moving plate 201. When the rotating shaft 204 causes the fixed block 205 to rotate 180 degrees, the four pressing plates 206 correspond, thus clamping the rectangular optical glass and achieving [the desired effect]. This method quickly clamps and fixes optical glass of various specifications, avoiding uneven clamping force that could cause indentations or scratches on the surface of the optical glass, especially during clamping and flipping. This significantly improves the flexibility and efficiency of optical glass coating. After the angle of the rotating shaft 204 is adjusted, the operator pulls the slide bar 209 to slide inside the limiting box 208. The movement of the slide bar 209 causes the sliding plate 210 to slide inside the limiting box 208. The movement of the sliding plate 210 causes the two sets of compression rods 214 to slide inside the fixing tube 213. At this time, the first contraction spring 215 is compressed and contracted. Then, the operator releases the slide bar 209, and the first contraction spring 215 recovers its original position. The tension generated by the position allows the insert plate 211 to engage with the slot 212, enabling rapid fixation and limiting of the rotating shaft 204. This facilitates positioning when switching between the extrusion plate 206 and the curved plate 207, preventing loosening when the extrusion plate 206 or the curved plate 207 clamps the optical glass, and improving the stability during optical glass coating. The servo motor 221 is driven by the operator's controller, which in turn rotates the rotating rod 219. The rotation of the rotating rod 219 drives the rotation of the small sprocket 220. Through the cooperation of the large sprocket 218, the small sprocket 220, and the chain 222, the fixed shaft 217 is driven. Rotating inside the support plate 101, the rotation of the fixed shaft 217 drives the rotation of the support frame 216, and the rotation of the support frame 216 drives the clamping frame 1 to flip, thereby achieving the effect of quickly adjusting and flipping the optical glass, which facilitates the coating effect on both sides of the optical glass by the staff, and further improves the flexibility of the optical glass coating process. Through the cooperation between the retraction rod 223 and the second retraction spring 224, the connecting plate 203 can be buffered during the movement process, improving the stability of the moving plate 201 during movement. Through the design of the rubber pad 225, the phenomenon of rigid compression of the optical glass by the extrusion plate 206 and the arc plate 207 can be effectively avoided.

[0032] The worker places the collection frame 301 on top of the workbench 102. At this time, the worker rotates two sets of threaded rods 305 inside the threaded tube 304. The rotation of the threaded rods 305 causes the push plate 306 to slide inside the positioning box 302. At this time, multiple sets of positioning blocks 307 are inserted into the positioning groove 303, thereby achieving the effect of quick installation and disassembly of the collection frame 301. The collection frame 301 makes it easy for the worker to collect the dripping coating liquid, which is convenient for the worker to recycle the residue later.
