Description

Technical Field

[0001] This utility model relates to the field of tempered glass processing technology, and in particular to a continuous forming annealing furnace for tempered glass. Background Technology

[0002] Tempered glass, also known as reinforced glass, is glass with compressive stress on its surface. It is strengthened by tempering. Annealing furnace is a process used in manufacturing that involves heating multiple semiconductor wafers to affect their electrical properties. It is designed for different effects, such as heating wafers to activate them, transforming thin films into thin films or into wafer-substrate interfaces, making densely deposited thin films, changing the state of grown thin films, repairing implanted damage, moving dopants or transferring dopants from one thin film to another or from a thin film into a wafer substrate. Tempered glass processing requires heat treatment using an annealing furnace.

A rotating mechanism is provided on the base ring, and clamp seats for fixing tempered glass rods are fixedly connected to all six ends of the rotating mechanism.

[0004] In the above-mentioned device, no corresponding protective device is installed above the clamp seat.

As a result, the glass rod is easy to detach from the clamp seat during the rotation of the rotating cover. At the same time, there are no air holes on the side wall of the clamp seat, so the end of the glass rod inserted into the clamp seat cannot be heated.

[0005] Therefore, it is necessary to provide a continuous forming annealing furnace for tempered glass to solve the above-mentioned technical problems. Utility Model Content

[0025] The lifting device 2 can be an electric actuator, or a lead screw and a motor.

[0026] The bearing assembly 3 includes a bearing plate 31, which is slidably connected to several sets of support columns 9. Rectangular blocks 32 are installed on the outer walls of both sides of the bearing plate 31. The two sets of rectangular blocks 32 are respectively connected to the lifting device 2. A rotating assembly 8 is installed between the bottom and the interior of the bearing plate 31. An installation assembly 4 is installed on the top of the bearing plate 31.

[0027] The lowering device 2 controls the upward movement of the bearing plate 31 via the rectangular block 32, which causes the bearing plate 31 to block the bottom of the cylinder 1. When it moves downward, it disengages from the bottom of the cylinder 1. The bearing component 3 can be a rectangular plate or a circular plate.

[0028] The rotating assembly 8 includes a motor 81, which is fixedly connected to the bottom of the support plate 31. The output end of the motor 81 extends into the interior of the support plate 31, and a gear 82 is installed at the output end of the motor 81. Several sets of rotating shafts 84 are evenly installed at the bottom of the support plate 31. A gear 83 is installed on the outer wall of each set of rotating shafts 84. Each set of gears 83 meshes with the gear 82. The upper ends of the several sets of rotating shafts 84 are connected to the mounting assembly 4.

[0029] The output end of motor 81 drives gear 1 82 to rotate. Gear 1 82 drives mounting component 4 to rotate through several sets of gear 2 83 and rotating shaft 84. The rotating component 8 can be a motor-driven gear or a manually rotated gear.

[0030] The mounting assembly 4 includes a frustum 41, and several sets of rotating shafts 84 extend through to the upper end of the bearing plate 31. The top of each set of rotating shafts 84 is fixedly connected to the frustum 41. Several sets of air holes 42 are opened on the outer wall of each set of frustum 41, and a protective assembly 5 is connected to the top of each set of frustum 41.

[0031] The top of the frustum 41 has a groove. The glass rod to be annealed is inserted into the groove. Then, the protective component 5 is opened to ensure that the glass rod will not fall off during rotation. The mounting component 4 can be a frustum insertion type or a screw fastening type.

[0033] Each end of the telescopic rod 51 is fixed by friction. When the glass rod is inserted into the frustum 41, the ring rod 52 pulls the ring 53, thereby causing the telescopic rod 51 to extend to a certain height. The ring 53 then restricts the glass rod body to prevent it from falling off during rotation. The protective component 5 can be a protective cover or a ring.

[0035] After the fan 74 draws outside air into the rectangular shell 71, it is heated by the heating plate 76 and then sprayed out through the nozzles 72 on the round tube 73, thereby heating the glass rod. The heating component 7 can be electrically heated or electrically heated.

[0036] A control device 6 is installed on the outer wall of the cylinder 1. The control device 6 is electrically connected to the lifting device 2 and the motor 81 respectively. The control device 6 is a PLC controller.

[0037] The working principle of the tempered glass continuous forming annealing furnace provided by this utility model is as follows: After inserting the glass rod to be annealed into the installation component 4, the protective component 5 is opened to block the glass rod body. The lifting device 2 drives the bearing component 3 to move upward until the bottom of the cylinder 1 is closed. Then, the rotating component 8 is used to make the glass rod on the installation component 4 rotate at a uniform speed. At the same time, the heating component 7 is turned on to heat the glass rod inside the cylinder 1.

[0038] Compared with related technologies, the tempered glass continuous forming annealing furnace provided by this utility model has the following advantages:

[0039] Beneficial effects:

[0040] After the glass rod is inserted into the frustum 41, the ring rod 52 pulls the ring 53, thereby causing the telescopic rod 51 to extend to a certain height. This allows the ring 53 to restrict the glass rod, preventing it from falling off during rotation and affecting the annealing process. At the same time, the vent 42 on the side wall of the frustum 41 allows the glass rod inserted into the frustum 41 to come into contact with hot air, making it heat more evenly.
