Description

Technical Field

[0001] This invention relates to the technical field of annealing apparatus for optical glass production, specifically to an annealing apparatus for optical glass production that is easy to load and unload, and its method of use. Background Technology

[0002] Optical glass, as a type of glass used in the optical field, possesses properties such as altering the direction of light propagation and changing the relative spectral distribution of ultraviolet, visible, or infrared light. It plays a crucial role in numerous fields, including modern optical instruments, precision lenses, and optical communication. Its quality and performance directly affect the optical performance and reliability of related products. During the production process of optical glass, significant internal stress exists within the formed glass. This is because the glass undergoes rapid temperature changes and mechanical forces during molding, resulting in an uneven internal structure and generating internal stress. If this internal stress is not eliminated, it may cause deformation during subsequent processing or use due to stress release, severely affecting its dimensional accuracy and surface flatness, thereby reducing the imaging quality of optical components. Simultaneously, internal stress also reduces the glass's impact resistance, increasing the risk of breakage and lowering product yield and stability. To eliminate internal stress in optical glass, annealing is required during production. By heating the glass to a certain temperature range and holding it for a period of time, the atoms within the glass can undergo sufficient thermal motion, achieving structural homogenization and effectively eliminating internal stress.

[0003] Patent publication number CN120192085B describes an annealing device and its method for easy loading and unloading of optical glass. This invention comprises a placement frame, a fixing strip, a fixing spring, an electromagnetic suction block, a movable seat, and a rotating top bar. After the glass body inside the placement frame is annealed, a second electric push rod is controlled to retract, pushing the movable seat to slide on the surface of a limiting slide bar. This causes the movable seat to lift the rotating top bar, which then rotates and tilts at the top of the movable seat. This lifts the rotating plate at one end of the rotating top bar, causing the placement frame to rotate to a certain angle inside the storage slot. The electromagnetic suction block is then controlled to attract the fixing strip, moving it away from the glass body. This causes the movable block to slide on the corresponding mounting slide bar surface, compressing and deforming the fixing spring, thus facilitating the removal of the annealed glass body from the placement slot. Then, when the glass is heated, it may stick to the placement groove due to excessive temperature. This makes it inconvenient for workers to remove the glass from the placement groove. Furthermore, when clamping and unclamping the glass, workers need to manually open and close the electromagnetic clamp to install and remove the glass. There is a possibility that workers may forget to open the electromagnetic clamp, which could cause the glass to fall and get damaged. Summary of the Invention

[0006] According to the above technical solution, a spring sheet is fixed to the side wall of the slider, and the side of the spring sheet away from the slider is fixed to the top outer wall of the connecting plate.

[0007] According to the above technical solution, two sets of L-shaped frames are provided in the groove, and the two sets of L-shaped frames are symmetrically arranged with the center line in the vertical direction of the groove as the axis of symmetry. By providing two sets of L-shaped frames, it is convenient to pick up the glass.

[0008] According to the above technical solution, a lifting device is provided in the groove to support the glass, and a tapping device is also provided in the groove to facilitate the removal of the glass from the L-shaped frame.

[0009] According to the above technical solution, the lifting device includes: a protruding block, the protruding block being slidably mounted on the side wall of the connecting plate, and a lifting roller being fixed on the outer wall of the protruding block; A connecting block is fixed to the side wall of the protruding block, and the outer wall of the connecting block is provided with an inclined groove; The long block is fixed to the bottom of the L-shaped frame. A pressing rod is fixed to the side wall of the long block. The end of the pressing rod is in contact with the inner side of the inclined groove. When the pressing rod moves in the inclined groove, the inclined groove is subjected to pressing force, causing the connecting block to move upward.

[0010] According to the above technical solution, a guide plate is fixed on the outer wall of the protrusion, and the guide plate increases the contact area between the bottom of the glass and the hot airflow.

[0011] According to the above technical solution, the striking device includes: a sleeve, the sleeve being fixed to the side wall of the L-shaped frame, and a striking block being slidably installed on the inner side of the L-shaped frame; An L-shaped block is fixed to the end of a striking block. A return spring is fixed to the outer wall of the striking block, and the end of the return spring is fixed to the side wall of the sleeve. A movable plate is slidably installed on the inner side of the groove. A guide block is fixed to the side wall of the L-shaped block. A guide frame is slidably installed on the side wall of the movable plate. The inner side of the guide frame is slidably connected to the outer wall of the guide block.

[0012] According to the above technical solution, a hinge seat is fixed to the side wall of the L-shaped block, a rotating block is rotatably installed on the inner side of the hinge seat, a torsion spring is fixed to the side wall of the rotating block, the side of the torsion spring away from the rotating block is fixed to the inner side of the hinge seat, a stop block is fixed to the outer wall of the hinge seat, and a triangular block is fixed to the side wall of the movable plate. By setting the stop block, the rotation of the rotating block can be restricted.

[0013] A method for using an annealing apparatus for optical glass production that is easy to load and unload includes the following steps: S1. Prepare the glass to be annealed, then conduct a safety inspection of the equipment. After the inspection, place the glass to be annealed into the L-shaped frame. S2. After placing the glass in place, start the electric push rod to drive the L-shaped frame into the groove. When the glass is inserted into the groove, the two sets of L-shaped frames will move closer to each other to clamp and position the glass that needs to be annealed. S3. Once the glass is positioned, the heating cover can be moved above the glass to be annealed by activating the electric telescopic rod, and the annealing operation can be carried out by activating the electromagnetic heating base. S4. After annealing, the electric telescopic rod is activated to move the heating cover away from the top of the annealed glass. The electric push rod is activated to move the support frame out of the groove. When the L-shaped frame moves out of the groove, it will move away from each other, which will release the clamping on the glass and allow the annealed glass to be taken out.

[0014] This invention provides an annealing apparatus for optical glass production that is easy to load and unload, as well as a method for using it. It has the following beneficial effects: 1. This invention, by setting up an electric push rod, a connecting plate, a slider, and an L-shaped frame, allows two sets of L-shaped frames to be moved out of the groove after the glass processing is completed. This causes the annealed glass to extend out of the groove, and then the glass can be easily pulled out of the L-shaped frame by a pull-out method, making it easy to pick up. This prevents the annealed glass from sticking to the placement tool, which would be inconvenient for workers to pick up.

[0015] 2. By setting up spring plates, inclined blocks, and pressing blocks, this invention can automatically release the pressing operation on the glass when the L-shaped frame moves the glass out of the groove, and automatically press the glass in place when the L-shaped frame moves the glass into the groove for annealing. This prevents workers from forgetting to install and position the glass, which could easily cause the glass to fall and be damaged.

[0016] 3. By setting up a protruding block, lifting roller, connecting block, inclined groove, long block and extrusion rod, the present invention can enable the lifting roller to press the top of the glass in the L-shaped frame when the glass is removed, so as to support the glass and keep it horizontal when it is pulled out, preventing the glass from tilting and falling and being damaged when it is pulled out.

[0017] 4. When the L-shaped frame moves the glass downwards, the present invention can make the lifting roller leave the bottom of the glass, preventing the lifting roller from contacting the bottom of the glass and blocking the bottom of the glass, so that the bottom of the glass cannot fully contact the hot airflow, resulting in poor heating effect. By setting the guide plate, the hot airflow can be made to contact the bottom of the glass along the guide plate, so as to perform uniform annealing of the glass and prevent the bottom of the glass from having difficulty contacting the hot airflow, resulting in low processing efficiency.

[0018] 5. By incorporating a sleeve, a striking block, an L-shaped block, a return spring, a hinge seat, a rotating block, a stop block, a guide block, a guide frame, a moving plate, and a triangular block, this invention enables the striking block to strike the outer wall of the L-shaped frame when the glass is removed from the L-shaped frame. This causes the L-shaped frame to vibrate, and the vibration is transmitted to the glass, loosening the glass that is stuck in the L-shaped frame. This prevents the glass from sticking to the L-shaped frame and making it difficult to pull out. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0022] Please see Figures 1-8 One embodiment of the present invention is: an annealing device for optical glass production that is easy to load and unload, comprising: a mounting base 1, an electric telescopic rod 2, a heating cover 3, an electromagnetic heating base 4, a groove 5, an electric push rod 6, a connecting plate 7, a slider 8, an L-shaped frame 9, a spring plate 10, an inclined block 11, and an extrusion block 12; the heating cover 3 is slidably mounted on the side wall of the mounting base 1, the electric telescopic rod 2 is fixed to the side wall of the mounting base 1, the output end of the electric telescopic rod 2 is fixed to the bottom outer wall of the heating cover 3, the electromagnetic heating base 4 is detachably mounted on the inner side of the heating cover 3, the top of the mounting base 1 has a groove 5, the bottom of the mounting base 1 is fixed to the electric push rod 6, and the connecting plate 7 is fixed to the electric push rod. At the top output end of 6, a slider 8 is slidably mounted on the top of the connecting plate 7. An L-shaped frame 9 is fixed on the top of the slider 8. An inclined block 11 is fixed on the side wall of the slider 8. An extrusion block 12 is fixed on the inner side of the groove 5. The inclined surface of the inclined block 11 presses the bottom of the extrusion block 12, which allows the inclined block 11 to move under pressure. A spring sheet 10 is fixed on the side wall of the slider 8. The side of the spring sheet 10 away from the slider 8 is fixed on the top outer wall of the connecting plate 7. Two sets of L-shaped frames 9 are provided in the groove 5, and the two sets of L-shaped frames 9 are symmetrically arranged with the center line of the vertical direction of the groove 5 as the axis of symmetry. The two sets of L-shaped frames 9 facilitate the removal of glass.

[0023] By setting up an electric push rod 6, a connecting plate 7, a slider 8, and an L-shaped frame 9, after the glass processing is completed, the two sets of L-shaped frames 9 can be moved out of the groove 5, thereby causing the two sets of L-shaped frames 9 to pull out the annealed glass. Then, the glass can be easily pulled out from the L-shaped frame 9 by pulling, making it easy to pick up and preventing the annealed glass from sticking to the placement tool, which would be inconvenient for the staff to pick up. By setting up spring plate 10, inclined block 11 and pressing block 12, when the L-shaped frame 9 moves the glass out of the groove 5, the pressing operation on the glass can be automatically released. When the L-shaped frame 9 moves the glass into the groove 5 for annealing, the L-shaped frame 9 can automatically press and install the glass, preventing workers from forgetting to install and position the glass, which could easily cause the glass to fall and be damaged.

[0024] In this embodiment, when annealing the glass is required, the glass is inserted into the inner side of the two sets of L-shaped frames 9. After the glass is inserted, the electric push rod 6 is activated, causing the output end of the electric push rod 6 to move the connecting plate 7 downward. When the connecting plate 7 moves downward, it can move the slider 8 downward, causing the slider 8 to move the L-shaped frames 9 downward. When the L-shaped frames 9 move downward, the inclined block 11 moves away from the pressing block 12. Because the spring plate 10 is in a compressed state, the spring plate 10 can move the slider 8 to reset, causing the slider 8 to move the two sets of L-shaped frames 9 closer together, so that the L-shaped frames 9 can press and position the glass. After the glass is inserted into the groove 5, the heating cover 3 can be moved to the positioned position by activating the electric telescopic rod 2. After the glass is annealed, the electromagnetic heating seat 4 is activated to anneal the glass. After annealing, the electric telescopic rod 2 is activated to remove the heating cover 3 from the top of the annealed glass, exposing the glass. The electric push rod 6 is activated to move the connecting plate 7 upward, which in turn moves the slider 8 upward, which in turn moves the L-shaped frame 9 upward. When the connecting plate 7 moves upward, it moves the inclined block 11 upward. When the inclined surface of the inclined block 11 contacts the bottom of the pressing block 12, the inclined block 11 is subjected to pressure, which moves the slider 8, causing the two sets of L-shaped frames 9 to move away from each other, thereby releasing the pressure and positioning of the glass and allowing the glass to be pulled out of the L-shaped frame 9.

[0025] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, a lifting device is provided in the groove 5, which is used to support the glass. The lifting device includes: a protruding block 131, a lifting roller 132, a connecting block 133, a sloping groove 134, a long block 135, a pressing rod 136, and a guide plate 137. The protruding block 131 is slidably mounted on the side wall of the connecting plate 7. The lifting roller 132 is fixed to the outer wall of the protruding block 131. The connecting block 133 is fixed to the side wall of the protruding block 131. The sloping groove 134 is opened on the outer wall of the connecting block 133. The long block 135 is fixed to the bottom of the L-shaped frame 9. The pressing rod 136 is fixed to the side wall of the long block 135. The end of the pressing rod 136 is in contact with the inner side of the sloping groove 134. When the pressing rod 136 moves in the sloping groove 134, the sloping groove 134 is subjected to a pressing force, which causes the connecting block 133 to move upward. The guide plate 137 is fixed to the outer wall of the protruding block 131. The guide plate 137 increases the contact between the bottom of the glass and the hot airflow.

[0026] By setting up a protruding block 131, a lifting roller 132, a connecting block 133, an inclined groove 134, a long block 135, and a pressing rod 136, when the glass is removed, the lifting roller 132 can press the top of the glass inside the L-shaped frame 9, which can lift and support the glass, keep the glass horizontal when it is pulled out, and prevent the glass from tilting and falling and being damaged when it is pulled out. When the L-shaped frame 9 moves the glass downwards, it can cause the lifting roller 132 to leave the bottom of the glass, preventing the lifting roller 132 from contacting the bottom of the glass and blocking the bottom of the glass. This would prevent the bottom of the glass from making sufficient contact with the hot airflow, resulting in poor heating effect. By setting the guide plate 137, the hot airflow can be directed to contact the bottom of the glass along the guide plate 137, so that the glass can be annealed evenly, improving work efficiency.

[0027] The groove 5 is also equipped with a striking device for facilitating the removal of glass from the L-shaped frame 9. The striking device includes: a sleeve 141, a striking block 142, an L-shaped block 143, a return spring 144, a hinge seat 145, a rotating block 146, a stop block 147, a guide block 148, a guide frame 149, a moving plate 1410, and a triangular block 1411. The sleeve 141 is fixed to the side wall of the L-shaped frame 9. The striking block 142 is slidably mounted on the inner side of the L-shaped frame 9. The L-shaped block 143 is fixed to the end of the striking block 142. A return spring 144 is fixed to the outer wall of the striking block 142. The end of the return spring 144 is fixed to the side wall of the sleeve 141. The moving plate 1410 is slidably mounted on the inner side of the groove 5. The L-shaped block... A guide block 148 is fixed to the side wall of L-shaped block 143, and a guide frame 149 is slidably installed on the side wall of movable plate 1410. By setting the guide block 148 and the guide frame 149, the L-shaped block can be guided. The inner side of the guide frame 149 is slidably connected to the outer wall of the guide block 148. A hinge seat 145 is fixed to the side wall of L-shaped block 143. A rotating block 146 is rotatably installed on the inner side of hinge seat 145. A torsion spring is fixed to the side wall of rotating block 146. The side of the torsion spring away from rotating block 146 is fixed to the inner side of hinge seat 145. A stop block 147 is fixed to the outer wall of hinge seat 145. A triangular block 1411 is fixed to the side wall of movable plate 1410. By setting the stop block 147, the rotation of rotating block 146 can be restricted.

[0028] By setting up sleeve 141, striking block 142, L-shaped block 143, return spring 144, hinge seat 145, rotating block 146, stop block 147, guide block 148, guide frame 149, moving plate 1410 and triangular block 1411, when the glass is taken out from the L-shaped frame 9, the striking block 142 can strike the outer wall of the L-shaped frame 9, causing the L-shaped frame 9 to vibrate. The vibration is transmitted to the glass, loosening the glass that is stuck in the L-shaped frame 9, preventing the glass from sticking to the L-shaped frame 9 and making it difficult to pull out.

[0029] A method for using an annealing apparatus for optical glass production that is easy to load and unload includes the following steps: S1. Prepare the glass to be annealed, and then conduct a safety inspection of the equipment. After the inspection, place the glass to be annealed into the L-shaped frame 9. S2. After the glass is placed in place, the electric push rod 6 is activated, which drives the L-shaped frame 9 to extend into the groove 5. When the glass is inserted into the groove 5, the two sets of L-shaped frames 9 will move closer to each other to clamp and position the glass that needs to be annealed. S3. After the glass is positioned, the heating cover 3 can be moved above the glass to be annealed by activating the electric telescopic rod 2, and the annealing operation can be carried out by activating the electromagnetic heating base 4. S4. After annealing, by activating the electric telescopic rod 2, the heating cover 3 is moved away from the top of the annealed glass. By activating the electric push rod 6, the support frame can be moved out of the groove 5. When the L-shaped frame 9 moves out of the groove 5, the L-shaped frames 9 will move away from each other, which can release the clamping on the glass and remove the annealed glass.

[0030] In this embodiment, when the L-shaped frame 9 moves the glass upward from the groove 5, the two sets of L-shaped frames 9 will move away from each other. When the L-shaped frame 9 moves, it can move the long block 135, which in turn moves the extrusion rod 136 in the inclined groove 134. The extrusion rod 136 extrudes the inner side of the inclined groove 134, and the pressure on the inclined groove 134 can move the connecting block 133 upward. The connecting block 133 then moves the long block 135 upward, which in turn moves the long block 135 upward. This causes the protruding block 131 to move upward, which in turn moves the lifting roller 132 upward to lift the top of the glass, keeping the glass horizontal and making it easy to pull out. Furthermore, as the L-shaped bracket 9 moves the glass out of the groove 5, the sleeve 141 causes the striking block 142 to move upward, thereby causing the L-shaped block 143 to move the rotating block 146 upward. When the rotating block 146 moves upward and contacts the inclined surface of the triangular block 1411, the rotating block 146 will be subjected to compressive force, and the stop block 147 restricts the downward rotation of the rotating block 146. This causes the end of the rotating block 146 to press against the inclined surface of the triangular block 1411, causing... When the rotating block 146 is subjected to compressive force, it can drive the L-shaped block 143 to move towards the L-shaped frame 9, so that the L-shaped block 143 drives the striking block 142 to strike the outer wall of the L-shaped frame 9. When the L-shaped frame 9 moves, it will compress the return spring 144. When the rotating block 146 moves to a position where it is no longer in contact with the triangular block 1411, the return spring 144 will be in a compressed state, causing the return spring 144 to drive the striking block 142 to reset, so that the striking block 142 can perform the next striking operation.

[0031] When the L-shaped frames 9 come close together to press and position the glass, the L-shaped block 143 can drive the long block 135 to reset, the pressing rod 136 can press the inclined groove 134, and the connecting block 133 can move downward, so that the protruding block 131 moves downward on the connecting plate 7, and the lifting roller 132 moves away from the bottom of the glass and does not block the bottom of the glass, thus facilitating the contact of hot airflow with the glass. When the L-shaped frame 9 moves the L-shaped block 143 downward, the rotating block 146 can press the top of the triangular block 1411. The spring force coefficient of the return spring 144 is five times that of the torsion spring, which causes the rotating block 146 to be subjected to the squeezing force and rotate upward, and compresses the torsion spring. When the L-shaped block 143 is not moved and the striking block 142 is not struck, it is easy to cause the glass to vibrate and the glass to shift and tilt in the L-shaped frame 9 if the L-shaped frame 9 moves the glass downward and extends into the groove 5 for annealing.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
