Abstract
Description
Technical Field
[0001] This invention relates to the field of new materials, and in particular to an integrated device and method for treating the metallic surface of glass housings. Background Technology
[0002] With capacitive touchscreens becoming a key technology for human-computer interaction, glass covers are increasingly used in consumer products such as mobile phones, tablets, and home appliances. As glass covers become more prevalent, replacing metal casings with glass has become a significant design choice. However, due to the smooth surface of glass, its texture differs significantly from the metallic feel of metal casings, making the achievement of a metallic-looking glass casing surface treatment a crucial challenge. Achieving a metallic-looking surface finish on a glass casing requires surface etching at sub-zero temperatures, making temperature control a critical factor. The metallic-looking surface treatment process typically involves a sequence of cooling, maintaining a low temperature, and then heating. Since the glass housing is at room temperature when it is immersed in the surface treatment liquid, the overall temperature will rise towards room temperature after the glass housing exchanges heat with the surface treatment liquid. Therefore, it is necessary to first go through a cooling process to control the overall temperature to the target temperature of the surface etching process, and then start the surface etching process under low temperature and constant temperature conditions. After the surface etching process is completed, the glass housing needs to be heated to avoid the large temperature difference that would cause severe stress when it goes directly from low temperature to room temperature.
[0003] Chinese patent CN202010451864.0 employs a method of sequentially immersing a surface treatment liquid into a cold cavity and a glass casing. The cold cavity uses a cryogenic medium to pre-cool the surface treatment liquid in the liquid tank. After the glass casing is immersed, since it is at room temperature, heat exchange occurs between the two, slightly raising the temperature of the surface treatment liquid in the tank to the target sub-zero temperature. Its drawbacks include a limited surface area of the cold cavity, a long heat exchange time between it and the surface treatment liquid in the tank, condensation of frost on its surface, and the introduction of excess water after immersion, causing the surface treatment liquid concentration to decrease with repeated use, making product consistency difficult to control. Chinese patent CN202010450876.1 uses two storage tanks, one cold and one hot, to store the surface treatment liquid at low and room temperatures respectively. By raising and lowering the height of these tanks, the flow direction of the surface treatment liquid is controlled through potential energy changes, thereby regulating the temperature of the surface treatment liquid in the tank. It overcomes the shortcomings of Chinese patent CN202010451864.0, but requires complex mechanical equipment, the vertical reciprocating motion of the two storage tanks consumes a lot of energy, and the equipment occupies a large area and has a high cost. In view of this, it is necessary to provide an integrated device and method for treating the glass shell with a metallic texture surface with better temperature control and a more compact design. Summary of the Invention

The material basket is mounted on the lower surface of the cover plate, and a temperature sensor is also mounted on the cover plate, facing the bottom of the material basket. Baffles are provided on the side of the material basket, with gaps between the baffles. The glass housing is placed inside the material basket. The liquid tank contains a surface treatment liquid, and the liquid tank is equipped with a first... The system comprises a liquid tank, a second liquid tank, and a third liquid tank. The first liquid tank is disposed between the second and third liquid tanks. A first sidewall is provided between the first and second liquid tanks.

The third liquid tank is also provided with a cold trap device. A first connecting pipe is also provided on the first sidewall, and a valve is provided on the first connecting pipe. A second connecting pipe is also provided on the second sidewall.
[0005] In a further preferred embodiment, a traveling rail is provided, the top traveling rail is installed on the traveling rail, the second liquid tank and the third liquid tank are both provided with tank covers, the cold trap device is provided on the inner wall of the third liquid tank, and the outer wall of the cold trap device can contact the surface treatment liquid in the third liquid tank to exchange heat, so that the temperature of the surface treatment liquid in the third liquid tank is lower than -25°C.
[0006] In a further preferred embodiment, a compressed air source is also provided. The first airbag, the second airbag, and the third airbag are all provided with cavities and elastic parts. The width of the elastic part is greater than the width of the cavity. Each cavity is provided with an air pipe and a vent valve. An air pipe valve is provided on the air pipe. The air pipe is connected to the compressed air source. The first guide pipe connects the first liquid tank and the second liquid tank. The second guide pipe connects the first liquid tank and the third liquid tank. The vertical height of the second guide pipe is higher than the vertical height of the first guide pipe.
[0007] In a further preferred embodiment, a control unit is also provided, which has an input port and an output port. The temperature sensor has an output port, which is connected to the input port of the control unit. The vent valve and the air pipe valve both have input ports, with the input port of the vent valve connected to the output port of the control unit, and the input port of the air pipe valve connected to the output port of the control unit.
[0008] A method for treating a glass casing with a metallic finish, the method comprising:
[0009] S101: The cylinder push rod pushes downward, causing the material basket to enter the first liquid tank;
[0010] S102: The second airbag is slowly inflated, and a portion of the surface treatment liquid in the third liquid tank flows into the first liquid tank through the second conduit, thereby reducing the temperature of the surface treatment liquid in the first liquid tank.
[0011] S103: After the temperature of the surface treatment liquid in the first liquid tank drops to the first temperature, the second airbag deflates.
[0012] S104: Start timing the surface treatment process. After the specified time is reached, the third airbag is inflated, so that a portion of the surface treatment liquid in the first liquid tank flows back to the third liquid tank through the second conduit.
[0013] S105: The third airbag deflates while the first airbag inflates, causing the surface treatment liquid in the second liquid tank to flow into the first liquid tank through the first conduit, thereby increasing the temperature of the surface treatment liquid in the first liquid tank.
[0014] S106: Cylinder retraction push rod;
[0015] S107: The first airbag deflates.
[0016] The second airbag inflates slowly, and a portion of the surface treatment liquid in the third liquid tank flows into the first liquid tank through the second conduit, causing the temperature of the surface treatment liquid in the first liquid tank to decrease. Specifically, this also includes...
[0017] The air valve of the second airbag is opened, connecting the air tube of the second airbag to the compressed air source. Compressed air enters the second airbag, and the elastic part of the second airbag expands under the air pressure, reducing the effective volume of the surface treatment liquid in the third liquid tank. The surface treatment liquid in the third liquid tank flows into the first liquid tank through the second guide pipe.
[0018] Because the surface treatment liquid in the third liquid tank exchanges heat with the outer wall of the cold trap device, the temperature of the surface treatment liquid in the third liquid tank is below -25°C.
[0019] As the surface treatment liquid flowing from the third liquid tank mixes with the original surface treatment liquid in the first liquid tank, the temperature of the surface treatment liquid in the first liquid tank decreases.
[0020] After the temperature of the surface treatment liquid in the first liquid tank drops to a first temperature, the second airbag deflates, and the process also includes...
[0021] The control unit obtains the temperature of the surface treatment liquid in the liquid tank based on the temperature signal input from the temperature sensor at the input port. When the temperature of the surface treatment liquid in the liquid tank drops to a first temperature, the control unit outputs a shut-off signal from the output port to the air valve of the second airbag, disconnecting the connection between the air pipe of the second airbag and the compressed air source. The control unit also outputs an open signal from the output port to the vent valve of the second airbag, releasing the compressed air from the second airbag and restoring the elastic part of the second airbag to its pre-inflation state. This increases the effective volume of the surface treatment liquid in the third liquid tank, causing the liquid level in the third liquid tank to drop. The surface treatment liquid in the third liquid tank no longer flows into the first liquid tank through the second conduit.
[0022] The first temperature is -25°C.
[0023] The process of starting the surface treatment process and, after a specified time, inflating the third airbag to allow a portion of the surface treatment liquid in the first liquid tank to flow back to the third liquid tank via the second conduit, also includes...
[0024] The air valve of the third airbag is opened, so that the air pipe of the third airbag is connected to the compressed air source. Compressed air enters the third airbag, and the elastic part of the third airbag expands under the action of air pressure, causing the liquid level in the first liquid tank to rise to the height of the second guide pipe. Part of the surface treatment liquid in the first liquid tank flows into the third liquid tank through the second guide pipe until the liquid level in the first liquid tank is no longer higher than the height of the second guide pipe.
[0025] The third airbag deflates while the first airbag inflates, causing the surface treatment liquid in the second liquid tank to flow into the first liquid tank through the first conduit, thus raising the temperature of the surface treatment liquid in the first liquid tank. This also includes...
[0026] The control unit outputs a shut-off signal from the output port to the air pipe valve of the third airbag, disconnecting the connection between the air pipe of the third airbag and the compressed air source.
[0027] Simultaneously, the deflation valve of the third airbag, the air tube valve of the first airbag, and the valve of the first connecting tube are opened. The control unit outputs an opening signal from the output port to the deflation valve of the third airbag, and the control unit outputs an opening signal from the output port to the air tube valve of the first airbag.
[0028] The compressed air inside the third airbag is expelled, and the elastic part of the third airbag returns to its pre-inflation state.
[0029] Simultaneously, compressed air enters the first air chamber, and the elastic part of the first air chamber expands under the air pressure, causing the surface treatment liquid in the second liquid tank to flow into the first liquid tank through the first guide pipe until the liquid level in the second liquid tank is level with the liquid level in the first liquid tank.
[0030] The surface treatment liquid in the second liquid tank has a higher temperature than the first liquid tank. After the surface treatment liquid in the second liquid tank mixes with the original surface treatment liquid in the first liquid tank, the temperature of the surface treatment liquid in the first liquid tank rises. This causes the temperature of the material basket to rise, preventing stress or cracking due to excessive temperature difference with the environment when the material basket rises back into the air.
[0031] The first airbag deflation also includes,
[0032] Close the air pipe valve of the first airbag to disconnect the connection between the air pipe of the first airbag and the compressed air source.
[0033] Open the deflation valve of the first airbag, and the compressed air inside the first airbag is released. The elastic part of the first airbag returns to its pre-inflation state, and part of the surface treatment liquid in the first liquid tank flows into the second liquid tank until the liquid levels of the two tanks are equal.
[0034] Close the valve on the first conductor pipe.
[0035] Compared with the prior art, the present invention has the following beneficial effects: (1) The three liquid tanks are connected by side walls, which is compact and small in size; (2) The expansion of the elastic part of the airbag is achieved by means of compressed air, without mechanical moving parts, the cost of compressed air is low, and the overall operating cost is reduced; (3) The airbag is set on the two side walls of the liquid tanks that are connected to each other. With the help of the high thermal resistance characteristics of air, the heat insulation between the liquid tanks is also achieved, which achieves two benefits at once; (4) After the surface treatment process is completed, a part of the surface treatment liquid in the first liquid tank flows back to the third liquid tank through the second conduit, so that the cooling range required for the surface treatment liquid in the third liquid tank is smaller, which is conducive to energy saving and consumption reduction.

The cold trap device is installed on the inner wall of the third liquid tank 13. The outer wall of the cold trap device can contact the surface treatment liquid in the third liquid tank 13 to exchange heat, so that the temperature of the surface treatment liquid in the third liquid tank 13 is lower than -25°C.

The input port of the vent valve is connected to the output port of the control unit, and the input port of the air pipe valve is connected to the output port of the control unit.
[0047] A method for treating a glass casing with a metallic finish, the method comprising:
[0048] S101: The cylinder push rod 61 pushes downward, causing the material basket 2 to enter the first liquid tank 11;
[0049] S102: The second airbag 17 is slowly inflated, and a portion of the surface treatment liquid in the third liquid tank 13 flows into the first liquid tank 11 through the second conduit 9, thereby reducing the temperature of the surface treatment liquid in the first liquid tank 11.
[0050] S103: After the temperature of the surface treatment liquid in the first liquid tank 11 drops to the first temperature, the second airbag 17 deflates.
[0051] S104: Start timing the surface treatment process. After the specified time is reached, the third airbag 18 is inflated, so that a portion of the surface treatment liquid in the first liquid tank 11 flows back to the third liquid tank 13 through the second guide pipe 9.
[0052] S105: The third airbag 18 deflates, while the first airbag 15 inflates, causing the surface treatment liquid in the second liquid tank 12 to flow into the first liquid tank 11 through the first conduit 8, thereby increasing the temperature of the surface treatment liquid in the first liquid tank 11.
[0053] S106: Cylinder 6 retracts and pushes out rod 61;
[0054] S107: First airbag 15 deflated.
[0055] The second airbag 17 is slowly inflated, and a portion of the surface treatment liquid in the third liquid tank 13 flows into the first liquid tank 11 through the second conduit 9, thereby lowering the temperature of the surface treatment liquid in the first liquid tank 11. Specifically, this also includes...
[0056] The air valve of the second airbag 17 is opened, connecting the air tube of the second airbag 17 to the compressed air source. Compressed air enters the second airbag 17, and the elastic part of the second airbag 17 expands under the air pressure, reducing the effective volume of the surface treatment liquid in the third liquid tank 13. The surface treatment liquid in the third liquid tank 13 flows into the first liquid tank 11 through the second guide pipe 9.
[0057] Because the surface treatment liquid in the third liquid tank 13 exchanges heat with the outer wall of the cold trap device, the temperature of the surface treatment liquid in the third liquid tank 13 is below -25°C.
[0058] As the surface treatment liquid flowing from the third liquid tank 13 mixes with the original surface treatment liquid in the first liquid tank 11, the temperature of the surface treatment liquid in the first liquid tank 11 decreases.
[0059] After the temperature of the surface treatment liquid in the first liquid tank 11 drops to a first temperature, the second airbag 17 deflates, and also includes...
[0060] The control unit obtains the temperature of the surface treatment liquid in the liquid tank based on the temperature signal input from the input port of the temperature sensor 41. When the temperature of the surface treatment liquid in the liquid tank drops to a first temperature, the control unit outputs a shut-off signal from the output port to the air pipe valve of the second airbag 17, disconnecting the connection between the air pipe of the second airbag 17 and the compressed air source. The control unit also outputs an open signal from the output port to the vent valve of the second airbag 17, releasing the compressed air from the second airbag 17. The elastic part of the second airbag 17 returns to its pre-inflation state, increasing the effective volume of the surface treatment liquid in the third liquid tank 13, causing the liquid level in the third liquid tank 13 to drop, and preventing the surface treatment liquid in the third liquid tank 13 from flowing into the first liquid tank 11 through the second conduit 9.

[0063] The air valve of the third airbag 18 is opened, so that the air pipe of the third airbag 18 is connected to the compressed air source. Compressed air enters the third airbag 18, and the elastic part of the third airbag 18 expands under the action of air pressure, causing the liquid level in the first liquid tank 11 to rise to the height of the second guide pipe 9. Part of the surface treatment liquid in the first liquid tank 11 flows into the third liquid tank 13 through the second guide pipe 9 until the liquid level in the first liquid tank 11 is no longer higher than the height of the second guide pipe 9.
[0064] The third airbag 18 deflates, while the first airbag 15 inflates, causing the surface treatment liquid in the second liquid tank 12 to flow into the first liquid tank 11 through the first conductive pipe 8, thereby raising the temperature of the surface treatment liquid in the first liquid tank 11. This also includes...
[0065] The control unit outputs a shutdown signal from the output port to the air pipe valve of the third airbag 18, disconnecting the connection between the air pipe of the third airbag 18 and the compressed air source.
[0066] Simultaneously, the deflation valve of the third airbag 18, the air tube valve of the first airbag 15, and the valve of the first connecting tube 8 are opened. The control unit outputs an opening signal from the output port to the deflation valve of the third airbag 18, and the control unit outputs an opening signal from the output port to the air tube valve of the first airbag 15.
[0067] The compressed air inside the third airbag 18 is expelled, and the elastic part of the third airbag 18 returns to its pre-inflation state.
[0068] Simultaneously, compressed air enters the first airbag 15, and the elastic part of the first airbag 15 expands under the air pressure, causing the surface treatment liquid in the second liquid tank 12 to flow into the first liquid tank 11 through the first guide pipe 8 until the liquid level in the second liquid tank 12 is flush with the liquid level in the first liquid tank 11.
[0069] The temperature of the surface treatment liquid in the second liquid tank 12 is higher than the first temperature. After the surface treatment liquid in the second liquid tank 12 mixes with the original surface treatment liquid in the first liquid tank 11, the temperature of the surface treatment liquid in the first liquid tank 11 rises. This causes the temperature of the glass housing in the material basket 2 to rise, preventing stress or cracking of the glass housing due to excessive temperature difference with the environment when the material basket rises back into the air.
[0070] The first airbag 15 is deflated, and it also includes,
[0071] Close the air pipe valve of the first airbag 15 to disconnect the connection between the air pipe of the first airbag 15 and the compressed air source.

The control unit also outputs an open signal from the output port to the vent valve of the second airbag, releasing the compressed air from the second airbag and restoring the elastic part of the second airbag to its pre-inflation state. The first temperature is -25°C.
7. The method for treating a glass casing with a metallic texture according to claim 4, characterized in that, The surface treatment process is timed from the start. After a specified duration, the third airbag inflates, causing a portion of the surface treatment liquid in the first liquid tank to flow back to the third liquid tank via the second conduit. This also includes... The air valve of the third airbag is opened, so that the air pipe of the third airbag is connected to the compressed air source. Compressed air enters the third airbag, and the elastic part of the third airbag expands under the action of air pressure, causing the liquid level in the first liquid tank to rise to the height of the second guide pipe. Part of the surface treatment liquid in the first liquid tank flows into the third liquid tank through the second guide pipe until the liquid level in the first liquid tank is no longer higher than the height of the second guide pipe.
8. The method for treating a glass casing with a metallic texture according to claim 4, characterized in that, The third airbag deflates while the first airbag inflates, causing the surface treatment liquid in the second liquid tank to flow into the first liquid tank through the first conduit, thus raising the temperature of the surface treatment liquid in the first liquid tank. This also includes... Disconnect the air tube of the third airbag from the compressed air source. Simultaneously open the deflation valve of the third airbag, the air tube valve of the first airbag, and the valve of the first connecting tube. The compressed air inside the third airbag is expelled, and the elastic part of the third airbag returns to its pre-inflation state. Simultaneously, compressed air enters the first air chamber, and the elastic part of the first air chamber expands under the air pressure, causing the surface treatment liquid in the second liquid tank to flow into the first liquid tank through the first guide pipe until the liquid level in the second liquid tank is level with the liquid level in the first liquid tank. The temperature of the surface treatment liquid in the second liquid tank is higher than the first temperature. After the surface treatment liquid in the second liquid tank mixes with the original surface treatment liquid in the first liquid tank, the temperature of the surface treatment liquid in the first liquid tank rises.
9. The method for treating a glass casing with a metallic texture according to claim 4, characterized in that, The first airbag deflation also includes... Close the air pipe valve of the first airbag to disconnect the connection between the air pipe of the first airbag and the compressed air source. Open the deflation valve of the first airbag, and the compressed air inside the first airbag is released. The elastic part of the first airbag returns to its pre-inflation state, and part of the surface treatment liquid in the first liquid tank flows into the second liquid tank until the liquid levels of the two tanks are equal. Close the valve on the first conductor pipe.
