One-piece tempering furnace

Abstract

The invention relates to a one-piece tempering furnace, comprising a groove body, a material shelf, and a wind circulating system. The groove body comprises a thermoregulation area and a chemical tempering area, wherein the thermoregulation area is arranged above the chemical tempering area, the thermoregulation area and the chemical tempering area are thermally isolated from the outside world, and the temperatures of the thermoregulation area and the chemical tempering area can be adjusted independently; the material shelf can move vertically in a one-dimensional direction and traverse between the thermoregulation area and the chemical tempering area; and the wind circulating system is arranged above the thermoregulation area so that the groove body becomes an airtight space and the temperature of the thermoregulation area can be adjusted. The one-piece tempering furnace has the advantages of simple structure, lower cost and practicability, and the product is isolated from the outside air to guarantee the preheating effect without suffering cold and hot impact, therefore, the one-piece tempering furnace can be applied to the window glass lens of a common mobile phone and to the strengthening of glass with a big size.

Description

technical field [0001] The invention relates to a tempering furnace, in particular to a tempering furnace with simple structure, low cost, and the product is isolated from the outside air, which not only ensures the preheating effect, but also does not suffer from cold and heat shocks. It is not only suitable for general mobile phone window glass lenses, It can also be applied to the upper and lower integrated tempering furnace for large-scale glass strengthening. Background technique [0002] Since the windows of mobile phones use a large number of light and thin glass lenses, in order to increase the strength of this type of glass lenses, the industry generally adopts a chemical tempering process to strengthen the glass lenses. The chemical tempering process can generally be divided into three stages. First, the glass lens is preheated; second, the glass lens is immersed in a high-temperature chemical agent (such as potassium nitrate molten salt) for chemical toughening; f...

Problems solved by technology

[0004] However, because mobile phone window glass lenses have the characteristics of small products, large quantities, various specifications, and thin thickness, there are unique requirements for the upper and lower integrated tempering furnaces. The existing conventional upper and lower integrated tempering furnaces have many shortcomings. For example, using In the case of a single-slot strengthening furnace, the product needs to be in contact with the air during the entire process, and is severely impacted by cold and heat, and the entire process is completed manually, with many uncontrollable factors

In addition, due to the severe impact of cold and heat, it is impossible to chemically toughen large-sized glass lenses, and there are doubts about personnel safety and the shortcomings of small single-machine output, so it is not suitable for mass production.

The three-slot integrated intensified furnace uses mechanical operation instead of personnel operation. Although it can reduce personnel safety hazards and has a large output, the product still needs to be in contact with air during the entire process and is subject to cold and heat shocks, and the three-slot integrated furnace is easily affected. Influenced by the series temperature of each tank, the temperature body is not perfect enough to chemically toughen large-size glass lenses

The structure of the three-slot "pin"-shaped strengthening furnace is a two-dimensional movement, and the stability of the two-dimensional movement structure is poor at high temperatures, especially when the steering transmission is prone to vibration, which will reduce the good rate of the product

[0006] The aforementioned glass tempering treatment device has the advantages of small size and is suitable for ordinary optical shops. However, when the aforementioned glass tempering treatment device is used, the product cannot avoid contact with the outside air during the preheating process, and its preheating effect cannot be guaranteed. In the cooling process, it is in contact with the outside air, and it is severely impacted by cold and heat, and the whole process is done manually, there are many uncontrollable factors, and there are doubts about the safety of personnel.

[0007] It can be seen that the above-mentioned existing upper and lower integrated tempering furnace obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
