Description

Technical Field

[0001] This utility model relates to the field of freezers, specifically to a freezer for assisting in the application of polarizing film. Background Technology

[0002] In the manufacturing process of display panels, the bonding of polarizers is one of the key steps. Freezing chambers are used as auxiliary equipment to process polarizers at specific temperatures in order to optimize the bonding effect.

[0003] Traditional freezing equipment for polarizing film application has a large contact area with the polarizing film due to its tray structure. During the application process, adhesion can easily damage the surface of the polarizing film, affecting the quality of the finished product. The fixed shelf structure of the equipment makes it difficult to accommodate the placement requirements of polarizing films of different sizes, thus limiting the applicability of the equipment. At the same time, condensation easily forms on the inner wall of the freezer due to the low temperature environment. The adhesion of moisture may interfere with the film application accuracy, causing bonding deviations. The refrigeration system has low efficiency, making it difficult to maintain the low temperature environment inside the freezer effectively, and the heat dissipation effect is poor, resulting in insufficient equipment operation stability and affecting the continuity and reliability of the film application process. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies by providing a freezing box for assisting in the application of polarizing film. This box avoids moisture affecting the application accuracy, ensures the stability of equipment operation, and solves the technical problems of existing technologies where moisture adhesion may interfere with the application accuracy, resulting in insufficient equipment operation stability and affecting the continuity and reliability of the application process.

[0005] The objective of this utility model is achieved through the following means:

[0006] A freezer for assisting in polarizer film application includes a freezer shell, an inner cavity of which is uniformly provided with anti-adhesion trays, the upper surface of which is uniformly provided with a raised array, and an adjustable shelf above each anti-adhesion tray. The inner wall of the freezer shell is coated with a hydrophobic coating. A temperature control component and a timer are installed on the surface of the freezer shell. A heat sink is installed on the upper surface of the freezer shell, and a fan is installed at the air outlet of the heat sink. A semiconductor cooling module is installed inside the heat sink, and ventilation slots are formed on the surface of the heat sink. A water tank is installed on the upper surface of the freezer shell, and water-cooling pipes are installed on the surface of the water tank and installed inside the heat sink. A radiator is installed on the surface of the water tank.

[0007] Furthermore, the outer layer of the freezer shell is made of stainless steel plate, the inner layer of the freezer shell is made of PP plastic layer, and a polyurethane foam layer is filled between the stainless steel plate and the PP plastic layer to reduce cold loss.

[0008] Furthermore, a drainage groove is provided at the bottom of the freezer outer shell, and a water receiving tray is installed at the bottom of the freezer outer shell. The drainage groove is used to drain the water that falls off the anti-condensation inner wall formed by the hydrophobic coating into the water receiving tray.

[0009] Furthermore, sliders are installed at the four corners of the adjustable shelf surface, and self-locking slide rails are installed inside the freezer shell at positions corresponding to the sliders. The adjustable shelf achieves adjustable shelf spacing through the self-locking slide rails to accommodate polarizers of different thicknesses.

[0010] Furthermore, a sealing door is installed on the surface of the freezer's outer shell, a silicone sealing strip is installed on the surface of the sealing door, and a magnetic latch is installed on the surface of the sealing door. The silicone sealing strip is embedded in the edge of the door, and together with the magnetic latch, the airtightness of the freezer is ensured.

[0011] Furthermore, the temperature control component includes a PT100 platinum resistance temperature sensor, a PID controller, and an LCD display. A water pump is installed at the water inlet of the water-cooling pipe, and the temperature range can be set and displayed in real time.

[0012] The beneficial effects of this utility model are: the raised array on the anti-adhesion tray reduces the contact area with the polarizer, effectively preventing damage caused by adhesion during the film application process; the adjustable shelf can adjust the spacing according to polarizers of different sizes, improving the applicability of the equipment; the hydrophobic coating on the inner wall of the freezer shell can reduce condensation and prevent moisture from affecting the film application accuracy.

[0013] The semiconductor cooling module enhances the transfer of cold energy through a fan, and combined with the water-cooled pipes, water tank, and radiator to form a circulating heat dissipation system, it can efficiently maintain the low temperature environment inside the freezer. The ventilation slots further assist in heat dissipation and ensure the stability of equipment operation. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] In this embodiment, refer to Figures 1-5 The freezer used to assist in applying polarizer film includes a freezer shell 1, an anti-adhesion tray 2 evenly distributed in the inner cavity of the freezer shell 1, a raised array 3 evenly distributed on the upper surface of the anti-adhesion tray 2, an adjustable shelf 4 above the anti-adhesion tray 2, a hydrophobic coating 5 on the inner wall of the freezer shell 1, a temperature control component 6 installed on the surface of the freezer shell 1, a timer 7 installed on the surface of the freezer shell 1, a heat sink 8 installed on the upper surface of the freezer shell 1, a fan 9 installed at the air outlet of the heat sink 8, a semiconductor cooling module 10 installed inside the heat sink 8, ventilation slots 11 opened on the surface of the heat sink 8, a water tank 12 installed on the upper surface of the freezer shell 1, water cooling pipes 13 installed on the surface of the water tank 12, the water cooling pipes 13 installed inside the heat sink 8, and a radiator 14 installed on the surface of the water tank 12.

[0022] The raised array 3 on the anti-adhesion tray 2 reduces the contact area with the polarizer, effectively preventing damage caused by adhesion during film application. The adjustable shelf 4 can adjust the spacing according to different sizes of polarizers, improving the applicability of the equipment. The hydrophobic coating 5 on the inner wall of the freezer shell 1 reduces condensation and prevents moisture from affecting the film application accuracy. The temperature control component 6, in conjunction with the timer 7, can accurately control the freezing temperature and time, ensuring that the polarizer is in a suitable low-temperature state for film application. The semiconductor cooling module 10 in the heat dissipation box 8 enhances the transfer of cold energy through the fan 9. Combined with the circulating heat dissipation system consisting of the water cooling pipe 13, water tank 12, and radiator 14, it can efficiently maintain the low-temperature environment inside the freezer. The ventilation slot 11 further assists in heat dissipation, ensuring the stability of equipment operation.

[0023] Timer 7: The freezing time can be set. After the set time is reached, the cooling will automatically turn off and an alarm will be triggered.

[0024] An emergency heating device is also installed at the bottom of the freezer outer shell 1: a low-power PTC heating element is integrated at the bottom of the freezer outer shell 1, which is activated when the temperature is low to prevent the PSA adhesive from hardening excessively;

[0025] Semiconductor cooling module 10: Located at the top of the enclosure, it uses the Peltier effect for cooling and forms a circulating air duct with fan 9 to ensure temperature uniformity;

[0026] The outer layer of the freezer shell 1 is made of stainless steel plate 15, and the inner layer of the freezer shell 1 is made of PP plastic layer 17. A polyurethane foam layer 16 is filled between the stainless steel plate 15 and the PP plastic layer 17 to reduce cold loss.

[0027] A drain groove 18 is provided at the bottom of the freezer outer shell 1, and a water receiving tray 19 is installed at the bottom of the freezer outer shell 1. The drain groove 18 is used to drain the water that falls off the anti-condensation inner wall formed by the hydrophobic coating 5 into the water receiving tray 19.

[0028] The adjustable shelf 4 has sliders 20 installed at each of the four corners of its surface. The interior of the freezer shell 1 is equipped with self-locking slide rails 21 at the corresponding positions of the sliders 20. The adjustable shelf 4 achieves adjustable shelf spacing through the self-locking slide rails 21 to accommodate polarizers of different thicknesses.

[0029] A sealing door 22 is installed on the surface of the freezer outer shell 1. A silicone sealing strip 23 is installed on the surface of the sealing door 22. A magnetic latch 24 is installed on the surface of the sealing door 22. The silicone sealing strip 23 is embedded in the edge of the door. Combined with the magnetic latch 24, the airtightness of the freezer is ensured.

[0030] The temperature control component 6 includes a PT100 platinum resistance temperature sensor, a PID controller, and an LCD display. A water pump is installed at the water inlet of the water-cooling pipe 13. The temperature range can be set and displayed in real time.

[0031] This solution involves placing the polarizer on an anti-sticking tray 2 with a raised array 3 inside the freezer casing 1. The spacing between layers is adjusted using the adjustable shelf 4 with four corner sliders 20 sliding on a self-locking slide rail 21, based on the polarizer thickness. The sealing door 22, equipped with a silicone sealing strip 23 and a magnetic latch 24, is closed. The temperature range is set via the temperature control component 6, which uses a PT100 platinum resistance temperature sensor to detect the temperature. A PID controller regulates the temperature, and the LCD screen displays the result in real-time. A timer 7 sets the freezing time. The semiconductor refrigeration module 10 utilizes the Peltier effect for cooling, and a fan 9 enhances the transfer of cold air to form a circulating airflow. Water from the water tank 12 is pumped into the water-cooling pipe 13, forming a circulating cooling system with the radiator 14. Ventilation slots 11 assist in heat dissipation. When the temperature is low, the low-power PTC heating element of the bottom emergency heating device activates to prevent excessive hardening of the PSA adhesive. During freezing, the hydrophobic coating 5 on the inner wall reduces condensation adhesion, and any detached water is drained through the drain trough 18 to the drip tray 19. Upon reaching the set time, the timer 7 automatically shuts off the cooling and triggers an alarm.

[0032] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
