Description

Technical Field

[0001] The present invention belongs to the technical field of multi-focus progressive lens manufacturing, and specifically relates to an alloy disc handle melting device for multi-focus progressive lens manufacturing. Background Art

[0002] Multi-focus progressive lenses are also called progressive lenses. As the name implies, there are multiple focal points on one lens. In the prior art, during the production of progressive lenses, generally, the cleaned lenses are first conveyed to a film laminating machine through a conveyor belt. The substrate (original lens) is taken out by a robotic arm and rotated and moved to a workbench. After attaching a protective film and cutting it, the protective film can completely cover the substrate. Then, a disc handle needs to be welded to the protective film with a low-temperature alloy to facilitate fixing the lens during subsequent grinding. The lens with the disc handle welded is temporarily stored and cooled and solidified in a cooling bin to ensure the firm connection between the disc handle and the protective film. Subsequently, it is conveyed to a grinding device. The disc handle matches the fixing tooling in the grinding device, and the two are combined to complete the fixing of the lens. Then, grinding starts. After grinding is completed, the disc handle and the protective film are removed. Finally, after cleaning and drying, it enters processes such as film laminating and marking. The removed low-temperature alloy disc handle is first cleaned in a cold water tank, then remelted and collected in a warm water tank for reuse.

[0003] In the above production process, after the removed alloy disc handle is heated and melted into a liquid state in the warm water tank, it is difficult to take out. Even if the alloy disc handle is placed in a heating dish, since the heating dish is in the water, tools are needed to pick it up. However, the heat radiating upward from the warm water tank is easy to scald the human body, and the hot water is mixed with the molten alloy disc handle, and separation can only be carried out after waiting for cooling. After cooling, the water in the heating dish also cools correspondingly, and pouring it back into the warm water tank will reduce the water temperature. Summary of the Invention

[0004] To solve the problem that it is relatively difficult to take out the molten alloy disc handle proposed in the above background art, the present invention provides an alloy disc handle melting device for multi-focus progressive lens manufacturing.

[0005] To solve the above problems, the solution adopted by the present invention is as follows: An alloy disc handle melting device for multi-focus progressive lens manufacturing includes a warm water tank composed of a box body and transparent windows installed on both sides of the box body. An electric control heating box for heating the inside of the warm water tank is installed at the bottom of the warm water tank. It further includes: a top cover that is snap-fitted on the top of the warm water tank; a lifting mechanism that is installed inside the warm water tank and extends below the warm water tank; a guiding mechanism that is symmetrically arranged on both sides of the top of the lifting mechanism; a bearing mechanism that is arranged on the top of the lifting mechanism and is connected to the lifting mechanism through the guiding mechanism; an adjusting mechanism that is divided into two parts and is respectively arranged on the top of the bearing mechanism and the top cover; and a blocking frame that is installed on the top of the top cover.

[0006] Preferably, the top cover includes a plate body, a movable plate, and a first elastic member. The plate body is engaged with the box body. Two slot holes are formed in the plate body for the carrying mechanism to pass through. The movable plate is elastically movable on both sides of the slot hole through the first elastic member and incompletely blocks the slot hole. The movable plate is in an isosceles trapezoid shape.

[0007] Preferably, feeding holes are formed at one ends of the two movable plates close to each other. The two feeding holes are combined into a square and are located directly above the carrying mechanism.

[0008] Preferably, the lifting mechanism includes a positioning column, a movable column, a screw rod, and a control rod. The positioning column is installed inside the box body and its bottom end extends below the box body. The movable column is slidably connected inside the positioning column. One end of the screw rod is rotatably connected to the positioning column and the other end is threadedly connected to the movable column. The control rod is rotatably connected to the positioning column. The control rod and the screw rod are connected by a helical gear.

[0009] Preferably, the guiding mechanism includes guiding columns, a rubber hose, a first connecting column, a second elastic member, and a protection baffle. The guiding columns are symmetrically installed at both ends of the top of the movable column. The rubber hose and the first connecting column are both installed at the top of the guiding column. The first connecting column is elastically connected to the carrying mechanism through the second elastic member. The protection baffle is arranged on the side of the second elastic member away from the rubber hose and is fixedly connected to the carrying mechanism.

[0010] Preferably, the carrying mechanism includes a fixed frame, an annular frame, and a carrying disk. The fixed frame is slidably connected to the surface of the first connecting column. The annular frame is fixed to the bottom of the fixed frame. The carrying disk is fixedly connected to the inner circle of the annular frame. The carrying disk is made of rubber. There is a gap between the fixed frame and the carrying disk.

[0011] Preferably, a drainage groove is formed inside the guiding column. The annular frame is communicated with the drainage groove inside the guiding column through the rubber hose. The protection baffle is specifically fixedly connected to the fixed frame. The axial section of the first connecting column is in a T shape.

[0012] Preferably, the adjusting mechanism includes a fixing plate, a first magnetic block, a second connecting column, and a second magnetic block. The fixing plates are symmetrically installed at the top of the fixed frame and at both ends above the first connecting column. The first magnetic block is slidably connected to the inner sides of the two fixing plates. The second connecting column is installed at both ends of the slot hole on the surface of the plate body. The second magnetic block is installed at the top of the second connecting column.

[0013] Preferably, when the second magnetic block and the first magnetic block are at the same height, the first magnetic block can be driven to approach the second magnetic block by suction. At this time, there is no block at the top of the first connecting column.

[0014] The technical effects of the present invention are as follows: Through the design of the lifting mechanism, the present invention can drive the carrying mechanism to move upward, so as to reach above the top cover by extrusion, and then it is convenient to take out the molten alloy disc handle. The provided adjusting mechanism can ensure that when the lifting mechanism drives the carrying mechanism to move upward before reaching a certain height, the carrying mechanism will not deform due to extrusion. And after reaching the specified height, due to the magnetic adsorption effect, the adjusting mechanism no longer blocks the diversion mechanism. And at this time, the blocking frame blocks the carrying mechanism. When the lifting mechanism drives the carrying mechanism to move through the diversion mechanism, the position of the carrying mechanism will not change but it will be extruded and deformed, thereby squeezing out the hot water inside. The hot water returns to the inside of the box through the diversion mechanism, reducing the impact on the water temperature.

[0015] Through the limit of the fixed frame by the blocking frame in the present invention, when the magnetic block 1 does not block the connecting column 1, the movable column extrudes the bottom of the carrying plate, and the bottom of the carrying plate bulges upward. The molten alloy disc handle is distributed in the low-lying areas inside the carrying plate under the action of gravity and forms a ring after cooling, which is more convenient to take out.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] As Figures 1 to 10 shown, the present invention provides an alloy disc handle melting device for manufacturing multi-focus progressive lenses, including a warm water tank 1 composed of a box body 101 and transparent windows 102 installed on both sides of the box body 101. An electric control heating box 3 for heating the inside of the warm water tank 1 is installed at the bottom of the warm water tank 1, and further includes: A top cover 2, which is snap-fitted on the top of the warm water tank 1; A lifting mechanism 4, which is installed inside the warm water tank 1 and extends below the warm water tank 1; A flow guiding mechanism 5, which is symmetrically arranged on both sides of the top of the lifting mechanism 4; A carrying mechanism 6, which is arranged on the top of the lifting mechanism 4 and is connected to the lifting mechanism 4 through the flow guiding mechanism 5; An adjusting mechanism 7, which is divided into two parts and is respectively arranged on the top of the carrying mechanism 6 and the top cover 2; A blocking frame 8, which is installed on the top of the top cover 2.

[0029] Adopting the above scheme: The design of the lifting mechanism 4 can drive the carrying mechanism 6 to move upward, so as to reach above the top cover 2 by extrusion, and then it is convenient to take out the molten alloy disc handle. The set adjusting mechanism 7 can ensure that when the lifting mechanism 4 drives the carrying mechanism 6 to move upward before the carrying mechanism 6 reaches a certain height, the carrying mechanism 6 will not be deformed due to extrusion. And after reaching the specified height, due to the magnetic adsorption effect, the adjusting mechanism 7 no longer blocks the flow guiding mechanism 5, and at this time, the blocking frame 8 blocks the carrying mechanism 6. When the lifting mechanism 4 drives the carrying mechanism 6 to move through the flow guiding mechanism 5, the carrying mechanism 6 will not change its position but will be deformed by extrusion, and then the hot water inside will be extruded. The hot water returns to the inside of the box body 101 through the flow guiding mechanism 5, reducing the influence on the water temperature.

[0030] As shown Figure 3 In the figure, the top cover 2 includes a plate body 201, a movable plate 202, and a first elastic member 203. The plate body 201 is engaged with the box body 101. Two slot holes are formed in the plate body 201 for the bearing mechanism 6 to pass through. The movable plate 202 is elastically movable on both sides of the slot hole through the first elastic member 203 and incompletely seals the slot hole. The movable plate 202 is in an isosceles trapezoid shape.

[0031] With the above solution: the formed slot holes enable the bearing mechanism 6 to pass through, and the top and bottom surfaces of the provided movable plate 202 are both inclined. In this way, when the movable column 402 drives the bearing mechanism 6 to move upward through the diversion mechanism 5, the movable plate 202 can be pressed by the pressure and move towards the inside of the plate body 201. After the bearing mechanism 6 passes over the movable plate 202, under the elastic force of the first elastic member 203, the two movable plates 202 come into contact again. At this time, there is a gap between the movable plate 202 and the movable column 402. This gap can allow hot water to flow back and can also prevent the pressure inside the box body 101 from being too high due to high temperature when the bearing mechanism 6 is above the movable plate 202.

[0032] As shown Figure 3 In the figure, feeding holes are formed at one ends of the two movable plates 202 close to each other. The two feeding holes are combined into a square and are located directly above the bearing mechanism 6.

[0033] With the above solution: the feeding holes are located directly above the bearing mechanism 6, enabling feeding through the feeding holes, which is relatively convenient to use. At the same time, the feeding holes can also prevent the pressure inside the box body 101 from being too high due to high temperature.

[0034] As shown Figure 5 In the figure, the lifting mechanism 4 includes a positioning column 401, a movable column 402, a screw 403, and a control rod 404. The positioning column 401 is installed inside the box body 101 and its bottom end extends below the box body 101. The movable column 402 is slidably connected inside the positioning column 401. One end of the screw 403 is rotatably connected to the positioning column 401 and the other end is threadedly connected to the movable column 402. The control rod 404 is rotatably connected to the positioning column 401, and the control rod 404 is connected to the screw 403 through a helical gear transmission.

[0035] With the above solution: by rotating the control rod 404, the screw 403 can be driven to rotate, so that under the limitation of the positioning column 401, the movable column 402 moves upward. It should be noted that waterproof treatment needs to be done between the positioning column 401 and the movable column 402 to prevent water from entering.

[0036] As shown Figure 6 、 7As shown, the diversion mechanism 5 includes diversion columns 501, rubber hoses 502, first connecting columns 503, second elastic members 504 and protective baffles 505. The diversion columns 501 are symmetrically installed at both ends of the top of the movable column 402. Both the rubber hoses 502 and the first connecting columns 503 are installed at the top of the diversion columns 501. The first connecting columns 503 are elastically connected to the bearing mechanism 6 through the second elastic members 504. The protective baffles 505 are arranged on the side of the second elastic members 504 away from the rubber hoses 502 and are fixedly connected to the bearing mechanism 6.

[0037] With the above solution: under the limitation of the adjustment mechanism 7, the first connecting column 503 and the bearing mechanism 6 are in a fixed state. When the movable column 402 drives the first connecting column 503 to move upward through the diversion column 501, the whole bearing mechanism 6 will be driven to move upward synchronously. The arranged protective baffles 505 play a certain protective role for the second elastic members 504, preventing the movable plate 202 from contacting the second elastic members 504 and then jamming the second elastic members 504. The rubber hoses 502 are flexible and can ensure smooth drainage through deformation when the distance between the diversion column 501 and the bearing mechanism 6 changes.

[0038] As Figure 6 、 7 shown, the bearing mechanism 6 includes a fixing frame 601, an annular frame 602 and a bearing disc 603. The fixing frame 601 is slidably connected to the surface of the first connecting column 503. The annular frame 602 is fixed to the bottom of the fixing frame 601. The bearing disc 603 is fixedly connected to the inner ring of the annular frame 602. The bearing disc 603 is made of rubber. There is a gap between the fixing frame 601 and the bearing disc 603. Drainage grooves are formed inside the diversion column 501. The annular frame 602 is communicated with the drainage grooves inside the diversion column 501 through the rubber hoses 502. The protective baffles 505 are specifically fixedly connected to the fixing frame 601. The axial section of the first connecting column 503 is T-shaped.

[0039] Adopting the above scheme: The alloy disc handle is located inside the bearing disc 603. After being heated to a molten state, the bearing mechanism 6 can be driven by rotating the control rod 404 to move upward as a whole above the plate body 201. When the blocking frame 8 blocks the fixing frame 601, the adjusting mechanism 7 no longer blocks the first connecting column 503. At this time, when the movable column 402 continues to move upward, it will squeeze the bottom of the bearing disc 603, so that the excess hot water inside the bearing disc 603 flows into the annular frame 602 through the gap between the fixing frame 601 and the bearing disc 603. Subsequently, the hot water reaches the inside of the diversion column 501 through the rubber hose 502 and finally returns to the inside of the box body 101. By this way, the amount of hot water that needs to be cooled after being removed from the box body 101 with the bearing disc 603 can be reduced, heat dissipation is reduced, and by the movable column 402 squeezing the bottom of the bearing disc 603, the bottom of the bearing disc 603 bulges upward, and the molten alloy disc handle is distributed in the low-lying areas inside the bearing disc 603 under the action of gravity and forms a ring after cooling, which is more convenient to take out.

[0040] As Figure 3 , 8 shown, the adjusting mechanism 7 includes a fixing plate 701, a first magnetic block 702, a second connecting column 703 and a second magnetic block 704. The fixing plate 701 is symmetrically installed at the top of the fixing frame 601 and at both ends above the first connecting column 503. The first magnetic block 702 is slidably connected to the inner sides of the two fixing plates 701. The second connecting column 703 is installed at both ends of the slot on the surface of the plate body 201. The second magnetic block 704 is installed at the top of the second connecting column 703. When the second magnetic block 704 and the first magnetic block 702 are at the same height, the first magnetic block 702 can be driven by the suction force to approach the second magnetic block 704, and at this time, the top of the first connecting column 503 is unblocked.

[0041] Adopting the above scheme: The first magnetic block 702 is directly above the first connecting column 503 inside the box body 101, blocking the first connecting column 503 to prevent the movable column 402 from driving the bearing mechanism 6 to move upward as a whole inside the box body 101 and squeezing the bottom of the bearing disc 603, so as to extrude the molten alloy disc handle out of the bearing disc 603. When the first magnetic block 702 and the second magnetic block 704 reach the same height, under the adsorption action of the magnetic force, the first magnetic block 702 moves in the direction of the second magnetic block 704, thus no longer blocking the first connecting column 503. And since the blocking frame 8 has contacted the fixing frame 601 at this time, the upward movement of the movable column 402 will squeeze the bottom of the bearing disc 603 and make it bulge upward, discharging the excess hot water and returning it to the inside of the box body 101.

[0042] The working principle and usage process of the present invention: The hot water inside the box body 101 is heated by the electric control heating box 3, and the alloy disc handle to be melted is put into the inside of the bearing plate 603 through the feeding port on the movable plate 202. After the alloy disc handle presents a molten state, the control rod 404 is rotated to drive the screw rod 403 to rotate. Thus, under the limit of the positioning column 401, the movable column 402 drives the whole bearing mechanism 6 to move upward through the diversion column 501 and the first connecting column 503. During the upward movement of the whole bearing mechanism 6, the fixed frame 601 squeezes the two movable plates 202 and pushes them apart to both sides until the fixed frame 601 contacts the blocking frame 8. At this time, the fixed frame 601 cannot move upward, and the suction force of the second magnetic block 704 on the first magnetic block 702 causes the first magnetic block 702 to move towards the second magnetic block 704. With the continuous upward movement of the movable column 402, the first connecting column 503 slides upward inside the fixed frame 601, and the movable column 402 also synchronously squeezes the bottom of the bearing plate 603. The redundant hot water inside flows into the annular frame 602 through the gap between the fixed frame 601 and the bearing plate 603. Subsequently, the hot water reaches the inside of the diversion column 501 through the rubber hose 502 and finally flows back into the box body 101. Since the bottom of the bearing plate 603 is convex, the molten alloy disc handle is distributed in the low-lying areas inside the bearing plate 603 under the action of gravity. After cooling is completed, the alloy disc handle can be taken out.
