Description
Technical Field
[0001] This utility model relates to the field of annealing machine technology, specifically to an annealing machine for automotive glass lenses. Background Technology
[0002] Automotive glass lenses are special glass components integrated into the structure of automotive glass. They achieve light convergence, refraction, or scattering through special optical design and are mainly used in automotive lighting systems, sensing systems, and other scenarios. They combine optical performance with the structural safety of automotive glass. During the production process of automotive glass lenses, an annealing machine is used to slowly cool the glass temperature for the next processing step.
[0003] To this end, China Patent Network published a glass lens annealing device with application number 201821922880.8. The device heats the glass lens in a heating chamber and then cools it in a first cooling chamber, achieving slow cooling of the glass lens. At the same time, it is relatively natural cooling with high cooling efficiency, thereby improving the annealing efficiency. The tray and pad block play a role in fixing and supporting the glass lens. The pad block contacts the arc surface of the glass lens to prevent shaking or slipping during transportation.
[0004] Although the above-mentioned application meets the user's needs to a certain extent, there are still some defects in the use process. The specific problems are as follows: when performing heating and annealing operations on glass lenses in the heating chamber, due to the natural differences in the distance between different parts of the lens and the heating plate, it is easy to cause uneven heat reception in different areas, which in turn causes deviation in the overall heating state of the lens, affecting the working efficiency and annealing stability of glass lens processing. Based on this, this utility model designs an annealing machine for automotive glass lenses to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an annealing machine for automotive glass lenses, in order to solve the problem mentioned in the background art that when performing heating and annealing operations on glass lenses in a heating chamber, the natural differences in the distance between different parts of the lens and the heating plate easily lead to uneven heat reception in different areas, resulting in deviations in the overall heating state of the lens and affecting the working efficiency and annealing stability of glass lens processing.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an annealing machine for automotive glass lenses, comprising a machine body, wherein a uniform annealing assembly is installed inside the machine body, the uniform annealing assembly comprising an electric transmission machine, a heating chamber, a first cooling chamber, a second cooling chamber, and a cooling pipe;
[0007] An electric transmission machine is fixedly connected inside the machine body. A heating chamber, a first cooling chamber, and a second cooling chamber are arranged sequentially inside the machine body along the transmission direction of the electric transmission machine. A cooling pipe is fixedly connected inside the second cooling chamber, which can ensure that the temperature received by the automotive glass lens during the annealing process in each area is consistent, and avoid the problem of uneven stress distribution caused by local temperature differences.
[0008] A circulating cooling assembly is installed on one side of the machine body. The circulating cooling assembly includes a water tank, a connecting box, a bend, and a liquid pump.
[0009] A water tank is fixedly connected to one side of the machine body, and a connecting box is fixedly connected to the top of the water tank. A bent pipe is fixedly connected inside the water tank, and a liquid pump is fixedly installed inside the water tank. This pump can cool the coolant inside the cooling pipe and achieve closed-loop circulation and reuse, avoiding large consumption and waste of coolant and ensuring the performance of the cooling pipe.
[0010] Preferably, the uniform annealing assembly further includes a suction cup, a heating tube, a mounting box, a fan, and a ventilation slot;
[0011] The top of the electric transmission machine is fixedly connected to several suction cups, the heating chamber is fixedly connected to a heating tube, the top of the machine body is fixedly connected to a mounting box, and fans are fixedly installed at equal intervals inside the mounting box. Ventilation slots are opened inside both the first cooling chamber and the second cooling chamber.
[0012] Preferably, the circulating cooling assembly further includes ventilation holes, a threaded rod, an agitator, and a drive motor;
[0013] The machine body has several ventilation holes inside. A drive motor is fixedly installed on one side of the connecting box. The output shaft of the drive motor is fixedly connected to a threaded rod, and an agitator is threadedly connected to the outside of the threaded rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The uniform annealing assembly ensures that the temperature received by the automotive glass lens is consistent in all areas during the annealing process, avoiding uneven stress distribution caused by local temperature differences. At the same time, the ring-shaped heating and cooling pipes form a full-area enveloping thermal and cold field distribution around the automotive glass lens, ensuring that the distance between each part of the lens and the heating and cooling sources remains consistent during the annealing process. This further improves the uniformity of heating and cooling, ensuring the consistency of stress relief and the stability of optical performance after lens annealing.
[0016] 2. The circulating cooling component can cool the coolant inside the cooling pipe and achieve closed-loop recycling, avoiding large consumption and waste of coolant and ensuring the performance of the cooling pipe. At the same time, by starting the drive motor, the threaded rod can be rotated, which in turn causes the agitator to move back and forth, breaking the temperature stratification when the water is still, ensuring a more balanced water temperature distribution, shortening the cooling rate of the coolant, and improving the working efficiency of lens annealing.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-4 This utility model provides a technical solution: an annealing machine for automotive glass lenses, including a machine body 1, and a uniform annealing component 2 installed inside the machine body 1. The uniform annealing component 2 includes an electric transmission machine 201, a heating chamber 203, a first cooling chamber 204, a second cooling chamber 205, and a cooling pipe 209.
[0028] An electric transmission machine 201 is fixedly connected inside the machine body 1. The electric transmission machine 201 is electrically connected to the output terminal of an external power supply. The electric transmission machine 201 runs through the inside of the machine body 1 to facilitate the conveying of automotive glass and the loading and unloading of materials. Inside the machine body 1 and along the conveying direction of the electric transmission machine 201, there are sequentially arranged a heating chamber 203, a first cooling chamber 204, and a second cooling chamber 205. The heating chamber 203, the first cooling chamber 204, and the second cooling chamber 205 are separated by a circular partition. A cooling pipe 209 is fixedly connected inside the second cooling chamber 205. One end of the cooling pipe 209 is a liquid inlet pipe and the other end is a liquid outlet pipe.
[0029] A circulating cooling assembly 3 is installed on one side of the body 1. The circulating cooling assembly 3 includes a water tank 301, a connecting box 303, a bend 304, and a liquid pump 305.
[0030] A water tank 301 is fixedly connected to one side of the body 1. A water inlet pipe and a water outlet pipe are fixedly connected to both sides of the water tank 301, respectively. A connecting box 303 is fixedly connected to the top of the water tank 301. A bent pipe 304 is fixedly connected inside the water tank 301. The two ends of the bent pipe 304 are connected to the liquid inlet pipe and the liquid outlet pipe of the cooling pipe 209, respectively. A liquid pump 305 is fixedly installed inside the water tank 301.
[0031] The uniform annealing assembly 2 also includes a suction cup 202, a heating tube 206, a mounting box 207, a fan 208, and a ventilation groove 210;
[0032] Several suction cups 202 are fixedly connected to the top of the electric transmission machine 201. Heating tubes 206 are fixedly connected inside the heating chamber 203. A mounting box 207 is fixedly connected to the top of the machine body 1. A ventilation mesh plate is fixedly connected inside the mounting box 207 to ensure the performance of the fan 208. The fan 208 is fixedly installed at equal intervals inside the mounting box 207. The fan 208 is electrically connected to the output terminal of an external power supply. Ventilation slots 210 are opened inside the first cooling chamber 204 and the second cooling chamber 205. The first cooling chamber 204 and the second cooling chamber 205 communicate with the inside of the mounting box 207 through the ventilation slots 210.
[0033] The automotive glass lens is placed on suction cup 202, which uses negative pressure adsorption to flexibly fix the lens, avoiding mechanical clamping damage and ensuring stability during processing. The electric conveyor 201 is started, and the lens enters the machine body 1 via the conveyor belt, moving sequentially into heating chamber 203, first cooling chamber 204, and second cooling chamber 205. Circular partitions separate the chambers to prevent temperature interference at different stages. When the lens enters heating chamber 203, heating tube 206 starts working, heating the entire lens area. This ensures the automotive glass lens is fully heated before annealing, increasing its initial temperature and preventing breakage. The lens then slowly enters the first cooling chamber 204 for cooling. When the fan 208 is started, it sends room temperature airflow into the automotive glass lens inside the first cooling chamber 204 through the ventilation slot 210, and the blown-out hot air is discharged to the outside through the ventilation hole 302, which performs preliminary air cooling of the automotive glass lens to avoid stress rebound caused by direct entry into the low temperature environment. After the lens enters the second cooling chamber 205, the circulating cooling component 3 continuously provides cooling. The low temperature coolant in the cooling pipe 209 exchanges heat with the air in the second cooling chamber 205 through the pipe wall. With the airflow circulation of the fan 208, the automotive glass lens is rapidly cooled. After the lens is deeply cooled by the second cooling chamber 205, it is moved out of the machine body 1 by the electric transmission machine 201, and the lens is removed from the suction cup 202, completing the single annealing operation.
[0034] The circulating cooling assembly 3 also includes a ventilation hole 302, a threaded rod 306, a stirring plate 307, and a drive motor 308;
[0035] The interior of the machine body 1 has several ventilation holes 302. A drive motor 308 is fixedly installed on one side of the connecting box 303. The drive motor 308 is electrically connected to the output terminal of an external power supply. A threaded rod 306 is fixedly connected to the output shaft of the drive motor 308. An agitator 307 is threadedly connected to the outer side of the threaded rod 306.
[0036] Start the liquid pump 305 to allow the coolant in the water tank 301 to enter the cooling pipe 209 of the second cooling chamber 205 through the bend pipe 304. After cooling the coolant inside the cooling pipe 209, a closed-loop circulation reuse is achieved. At the same time, start the drive motor 308, which drives the threaded rod 306 to rotate, causing the agitator plate 307 to move back and forth in the water tank 301, agitating the water to enhance the heat dissipation efficiency of the bend pipe 304, ensuring the initial temperature of the coolant is stable, shortening the cooling rate of the coolant, and improving the working efficiency of lens annealing. When it is necessary to replace the water in the water tank 301, open the outlet valve to drain the used water, close the valve, and then add water to the water tank 301 through the inlet pipe.
