Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning device for optical molds. Background Art

[0002] With the advancement of modern technology, product quality is constantly improving, and the yield requirements for optical film products are becoming increasingly stringent. Product quality is not only controlled during the processing itself, but also influenced by the environment. For example, optical molds are subject to fluctuations in ambient temperature and humidity during transportation, which can easily cause the surface to become contaminated by airborne dust and moisture, as well as debris and oil stains from the processing process. Failure to remove these stains during production can reduce production yields and interfere with mold inspection, leading to inaccurate yield rates.

[0003] Therefore, during the optical mold processing process, the requirements for temperature, humidity, and environmental quality control are gradually increasing. To improve product quality and ensure the output quality of processing equipment, a common approach is to install large-scale auxiliary equipment in the factory to control environmental conditions. However, this type of control requires a significant amount of manpower and material resources, and requires the planning and construction of the corresponding auxiliary equipment during the initial construction of the factory. Therefore, this approach has limited applicability.

[0004] In addition, some companies use cleaning equipment to clean the surface of optical molds. One method involves using a dry ice blaster to clean the surface of optical molds. This uses the impact force of small-particle dry ice sprayed on the mold to remove foreign matter from the mold structure, while the instantly vaporized CO2 carries the foreign matter away. However, this type of device can only be used in a low-humidity and dust-free environment, as these operations will reduce the temperature of the mold surface in areas not affected by the spray. Under normal circumstances, water molecules in the air will adsorb on the metal mold surface, causing secondary contamination.

[0005] Other methods use ultrasonic immersion cleaning or suspended cleaning with upward and downward flushing. However, both require large quantities of cleaning fluid. Furthermore, inappropriate ultrasonic frequencies can easily cause weld failure in the mold body. Suspended cleaning, on the other hand, requires a large operating area. Therefore, existing methods for cleaning optical mold surfaces all have certain drawbacks and are limited in their universal applicability. Utility Model Content

[0029] See also Figure 1-4The utility model is a cleaning device for optical molds, comprising a cleaning box 1, a mounting seat, a power assembly 2 and a cleaning assembly 3. The cleaning box 1 can be a square structure used as a container to accommodate the workpiece to be cleaned and to store the cleaning liquid used for cleaning. The lower end of the cleaning box 1 can be provided with a discharge port and connected to a purification box for purifying and circulating the used cleaning liquid. The purification box can use existing physical filtration, chemical reagents and other purification methods for water purification. A number of protective rollers are provided on the upper end of the side of the cleaning box 1. The protective rollers are made of a flexible material or at least coated with a flexible layer on the outside. It is used to play a protective role to avoid damage caused by bumps during use. Furthermore, a number of air inlets of exhaust fans can be provided on the upper end of the side of the cleaning box 1 to extract the water mist generated during the cleaning process downward to prevent the water mist from spreading.

[0030] See also Figure 1-4 In one embodiment of the present invention, the mounting seat is provided at both ends of the cleaning tank 1 and is used to fix and install the roller-shaped optical mold; the mounting seat may include an arc-shaped support structure at the lower end and a fixed structure at the upper end. The fixed structure may be arc-shaped, and one end is rotatably connected to the arc-shaped support structure at the lower end, and the other end is locked by a bolt. The mounting seat may also be provided as a circular structure and slidably arranged. When in use, one end of the mold shaft is first installed in a mounting seat, and then the position of the other mounting seat is adjusted close to the water tank, the other end of the mold shaft is installed therein and the other mounting seat is locked to achieve locking and support of the roller-shaped optical mold. The power assembly 2 is used to drive the optical mold to rotate; the power assembly 2 may include a servo motor and a connecting structure such as a coupling for connecting the motor and the roller-shaped optical mold.

[0031] See also Figure 1-4In one embodiment of the present invention, the cleaning assembly 3 includes several cleaning pipes arranged above the cleaning tank 1. These cleaning pipes are connected to a water tank and an air source, respectively, and are controlled by valves. Several atomizing nozzles 4 are installed on the cleaning pipes, with their outlets facing the cleaning tank 1. The atomizing nozzles 4 atomize pure water supplied from the water tank through the cleaning pipes and spray it onto the optical mold for cleaning. The cleaning pipes include a main pipe and branch pipes 5. The main pipe is connected to the water tank and the air source, respectively. Several branch pipes 5 are connected to the main pipe, and each branch pipe 5 is provided with a control valve. The atomizing nozzles 4 are installed on the branch pipes 5. The control valves can be used to control the opening and closing of the branch pipes 5. This allows the number of branch pipes 5 used to be controlled according to the specific dimensions of the mold, i.e., the coverage area of the water spray during cleaning, thereby maximizing the use of the cleaning liquid and reducing waste. Multiple local pipes 6 are connected to the branch pipes 5, each of which is provided with several atomizing nozzles 4, each of which is also provided with a control valve. The on-off of the local pipeline 6 can be controlled by the control valve, and the coverage area of the atomizing nozzle 4 put into use can be more finely regulated to correspond to the product to be cleaned, so as to maximize the utilization of the cleaning liquid and reduce waste.

[0032] The working principle of this utility model:

[0033] During operation, the roller-shaped optical mold is clamped and secured, then rotated by the power assembly 2 at a constant speed. Pure water supplied by the water tank is atomized by the atomizing nozzle 4 and sprayed onto the roller-shaped optical mold, cleaning the mold surface. Once cleaning is complete, the water tank is disconnected, and the air source is connected to the cleaning pipe. Dry, pure air is sprayed through the atomizing nozzle 4, and the speed of the power assembly 2 is increased, using centrifugal force to clean water stains from the mold surface. Once the mold is dry, the machine is stopped and removed.

[0034] This application uses the atomizing nozzle 4 to spray pure water and dry air in sequence, and performs a simple cleaning on the optical mold after processing is completed to remove debris, oil marks, dust, and water marks on its surface. It greatly improves the quality of the production mold and completes an important part of the refined operation; when the atomizing nozzle 4 is in operation, it can not only rinse the residual dirt on the surface, but also clean the oxide layer on the surface of the mold, which not only ensures the quality of the mold, but also improves the performance of the mold. The device has a simple structure and occupies a small space. In addition, the device can appropriately reduce the strict requirements for public auxiliary equipment, and does not require excessive public auxiliary equipment to maintain the cleanliness of the environment and energy consumption.
