Abstract
Description
Technical Field
[0001] The utility model relates to the field of glass lens processing, and more specifically to a glass lens annealing device. Background Art
[0002] The production process of optical glass generally includes batching, melting, pressing, annealing, testing and storage, among which annealing is a process after pressing. After pressing, the lens blank is removed by the removal device, and enters the mesh belt annealing furnace from the mold. The lens blank is reheated to the annealing temperature, maintained for a period of time, and then cooled at a controlled speed to eliminate internal stress. In the prior art, the annealing of glass lenses is often done by placing the lenses in the annealing furnace. In order to facilitate the retrieval and placement of multiple lenses to the corresponding discharge plate, a placement groove adapted to the size of the lens is opened on the surface of the discharge plate. The size of the placement groove on the surface of the existing discharge plate is slightly larger than the lens, so that the lens can be taken and placed. Therefore, the lens is only limited and not effectively fixed. It is easy to shake during transportation. If the discharge plate is tilted due to improper operation, the lens will fall and break. If a clamping mechanism is set, although it can effectively limit the lens, the contact surface with the clamping mechanism is easily deformed due to extrusion during the heating and return process, resulting in an increase in the defective rate.

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.
[0024] Example:
[0025] See also Figure 1-Figure 4As shown, a glass lens annealing device comprises an annealing furnace body 1 and a discharge plate 3. A sealing door is installed on the front side of the annealing furnace body 1 to form a sealed space inside the annealing furnace body 1. Track bars 2 are evenly arranged on both sides of the annealing furnace body 1. The track bars 2 are arranged horizontally in front and back, and the multiple track bars 2 on both sides correspond to each other. The discharge plate 3 is stacked in the annealing furnace body 1. Card grooves 19 are symmetrically opened below the two sides of the discharge plate 3. The track bars 2 and the inner dimensions of the card grooves 19 are adapted. Through the cooperation of the two, it is ensured that the discharge plate 3 placed in the annealing furnace body 1 is in a parallel state. The surface of the track bar 2 is evenly opened with placement grooves 4 for placing lenses. The placement grooves 4 are step grooves with a larger upper part and a smaller lower part. The lens to be annealed is placed in the placement groove 4 and supported by the step surface so that the upper and lower surfaces of the lens are both in a naked state. The upper area of the placement groove 4 is larger than the size of the lens, and a cavity 5 is opened in the center of the discharge plate 3. The cavity 5 is placed between two adjacent rows of placement grooves 4. Moving rods 6 are symmetrically and slidably installed inside the cavity 5. The two moving rods 6 are parallel to each other, and an extrusion plate 7 is provided on the side of the moving rods 6 that are away from each other. The extrusion plate 7 runs through the inner wall of the cavity 5, and multiple extrusion plates 7 correspond to the placement grooves 4 one by one. The end of the extrusion plate 7 that is away from the moving rod 6 is placed on one side of the upper step of the placement groove 4. When the two moving rods 6 are away from each other, the extrusion plate 7 can be moved to the center position of the placement groove 4 to clamp the lens. Tension springs 8 are symmetrically connected between the two moving rods 6. The tension of the tension springs 8 is used to make the two moving rods 6 approach each other when they are not under force. At this time, the end of the extrusion plate 7 is placed on one side of the placement groove 4, which will not cause extrusion to the lens, so as to facilitate loading and unloading.
[0026] Please refer to Figure 2-Figure 7 As shown, pressing bolts 9 are vertically slidably installed at both ends of the upper surface of the discharge plate 3, and a conical surface 10 is arranged at the bottom of the pressing bolt 9. The conical surface 10 is placed between the two moving rods 6, and the surfaces of the two moving rods 6 that are close to each other are in contact with the conical surface 10. When the pressing bolt 9 is pressed and moved downward, the moving rods 6 on both sides can be squeezed by the conical surface 10, so that the two moving rods 6 are separated from each other, thereby clamping the lens.
[0027] Among them, an extension rod 11 is arranged at the bottom of the conical surface 10, and the bottom of the extension rod 11 is hemispherical. A limiting concave ring 12 is opened at the lower outer side of the extension rod 11, and sliding cavities 13 are symmetrically opened on both sides inside the discharge plate 3. The sliding cavity 13 is opened horizontally, and the sliding cavity 13 is placed below the cavity 5. A slide plate 14 is slidably installed inside the sliding cavity 13, and a spring 18 is arranged inside the side where the two sliding cavities 13 are close to each other. The elastic force of the spring 18 makes the slide plate 14 always subjected to a force toward the side of the card slot 19, so that the limiting convex tooth 16 always keeps in contact with the surface of the extension rod 11 and squeezes it, and one end of the spring 18 is in contact with the end surface of the slide plate 14.
[0028] Please refer to Figure 5-Figure 7As shown, a through hole 15 is provided on the surface of the slide plate 14, and the extension rod 11 passes through the through hole 15. A limiting convex tooth 16 is provided on the side of the through hole 15 close to the spring 18. The limiting convex tooth 16 is adapted to the internal size of the limiting concave ring 12, and the pressing bolt 9 can only move vertically. When the pressing bolt 9 moves downward to clamp the extrusion plate 7 to the lens, the limiting concave ring 12 moves downward to cooperate with the limiting convex tooth 16. At this time, the extrusion arc surface 17 passes through the inside of the card slot 19, so that the extrusion arc surface 17 can be squeezed by the track bar 2 during installation, so that the slide plate 14 moves inwardly. At this time, the limiting convex tooth 16 is disengaged from the cooperation with the limiting concave ring 12, and then the pressing bolt 9 and the moving rod 6 are returned. The end of the slide plate 14 away from the spring 18 is provided with an extrusion arc surface 17, and the extrusion arc surface 17 passes through the inner wall of the card slot 19.
[0029] Working principle: When in use, the discharge plate 3 can be separated from the track bar 2, and then the lens to be annealed can be placed inside the placement groove 4, and supported by the small-sized step below the placement groove 4 to maintain stability. The large-sized step above the placement groove 4 is larger than the lens size. Due to the tension springs 8 on both sides, the two moving rods 6 are close to each other. When moving the discharge plate 3, the pressing bolt 9 can be pressed downward to drive the moving rods 6 on both sides away from each other through the conical surface 10, and then the end of the extrusion plate 7 is close to the center of the placement groove 4 to clamp and fix the lens. When the pressing bolt 9 moves downward, it can drive the extension rod 11 to move downward, so that the limiting concave ring 12 corresponds to the limiting convex tooth 16. At this time, due to the spring 18 The thrust force makes the limiting convex teeth 16 cooperate with the limiting concave ring 12 to limit the pressing bolt 9. At this time, the end of the extrusion arc surface 17 is placed in the card groove 19, and then the clamping force of the extrusion plate 7 on the lens is maintained. When the discharge plate 3 is placed in the annealing furnace body 1, the card groove 19 can be stuck on the surface of the track bar 2. At this time, the track bar 2 will squeeze the extrusion arc surface 17, so that the slide plate 14 moves inward, and then the limiting convex teeth 16 no longer cooperate with the limiting concave ring 12. At this time, the tension of the tension springs 8 on both sides is used to make the moving rod 6 close. At this time, the pressing bolt 9 moves back to its position, and the extrusion plate 7 no longer squeezes the lens to prevent the lens from being deformed due to extrusion after heating.
[0030] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
