Description

Technical Field

[0001] This utility model relates to the field of OCA optical adhesive technology, specifically to an anti-sticking knife device for slitting OCA optical adhesive. Background Technology

[0002] OCA optical adhesive has low surface energy and high viscosity. During the slitting process, the high-speed cutting of the blade can easily cause localized temperature rise.

[0003] The adhesion between the OCA adhesive layer and the blade surface is increased, resulting in adhesive residue on the blade edge and sides. Existing anti-sticking methods mostly rely on the blade surface coating, but it is prone to wear and failure during long-term slitting, and cannot continuously solve the problem of residual adhesive. The accumulation of residual adhesive will lead to burrs and dimensional deviations during subsequent slitting, reducing product yield. Currently, there is a lack of devices that can synergistically suppress residual adhesive from multiple dimensions such as temperature control, anti-sticking medium guidance, and static electricity elimination. Utility Model Content

[0004] In view of the problems existing in the above-mentioned anti-sticking knife device for cutting OCA optical adhesive, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an anti-sticking knife device for slitting OCA optical adhesive, which solves the problem of increased adhesion between the OCA adhesive layer and the knife body surface, resulting in adhesive residue on the blade edge and sides.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An anti-sticking knife device for slitting OCA optical adhesive includes a mounting base, a motor fixedly mounted on one side of the mounting base, a cutting blade fixedly mounted on the output end of the motor, a cooling shaft rotatably mounted on one side of the cutting blade, two cooling pipes fixedly mounted inside the cooling shaft, a pump body fixedly mounted on the wall of the cooling pipes, multiple cooling channels fixedly mounted inside the cutting blade, a support plate fixedly mounted on the top of the mounting base, a fan duct fixedly mounted on the top of the support plate, and an air pipe fixedly mounted on the top of the fan duct.

[0007] Preferably, a temperature control pad is fixedly provided on the inner sidewall of the two cooling pipes.

[0008] Preferably, an optical sensor and a signal processing module are fixedly mounted on the inner sidewall of the support plate.

[0009] Preferably, a partition is fixedly provided on the inner wall of the air duct.

[0010] Furthermore, a sealing ring is fixedly provided on the outer wall of the cooling channel.

[0011] Preferably, the outer side of the cutting tool is coated with a wear-resistant layer.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention utilizes a cooling system comprised of a cooling shaft, cooling pipe, pump body, and cooling channel to deliver cooling medium to the inside of the cutting tool. Combined with a temperature-controlled pad on the inner wall of the cooling pipe, the cooling temperature is precisely adjusted, effectively reducing localized temperature rise in the tool body during high-speed cutting. This reduces the increased adhesion of the OCA adhesive layer to the tool surface due to temperature increases, fundamentally inhibiting adhesive residue on the cutting edge and sides. Simultaneously, the air duct and air pipe work together to deliver airflow to the cutting contact area, helping to blow away any tiny adhesive particles that may be generated during cutting, preventing residual adhesive accumulation that could lead to burrs and dimensional deviations in subsequent cutting. This significantly improves cutting accuracy and product yield.

[0013] This invention features an optical sensor and signal processing module installed on the inner wall of the support plate. This sensor can collect and process image signals from the blade surface in real time, enabling timely detection of residual adhesive on the blade surface. This prevents the residual adhesive from continuously affecting the slitting quality, allowing staff to take timely maintenance measures based on the monitoring results. This ensures that the device remains in a stable anti-sticking slitting state for a long time, reducing production interruptions caused by residual adhesive.

[0014] In this invention, the baffle on the inner wall of the air duct can guide and divert the airflow, so that the airflow delivered to the air duct can act more evenly on the cutting area, avoiding the effect of excessively strong or weak local airflow affecting the anti-sticking effect. This allows the airflow to more accurately cover the cutting contact area between the blade edge and the OCA optical adhesive, further helping to block the adhesion between the adhesive layer and the blade, and improving the stability and reliability of the anti-sticking effect.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses an anti-sticking knife device for slitting OCA optical adhesive.

[0020] This utility model provides, for example Figure 1-3The device shown is an anti-sticking blade for slicing OCA optical adhesive, comprising a mounting base 1. A motor 2 is fixedly mounted on one side of the mounting base 1, and a cutting blade 3 is fixedly mounted on the output end of the motor 2. A cooling shaft 4 is rotatably mounted on one side of the cutting blade 3, and two cooling pipes 5 are fixedly mounted inside the cooling shaft 4. A pump body 6 is fixedly mounted on the wall of the cooling pipes 5. Multiple cooling channels 7 are fixedly mounted inside the cutting blade 3. A support plate 8 is fixedly mounted on the top of the mounting base 1, and a fan duct 9 is fixedly mounted on the top of the support plate 8. A fan duct 10 is fixedly mounted on the top of the fan duct 9. The mounting base 1 provides fixed support for the entire device. When the device is started, the motor 2 fixed on one side of the mounting base 1 outputs power, directly driving the cutting blade 3 fixed at its output end to rotate around its own axis, so that the cutting edge of the cutting blade 3 is capable of cutting OCA optical adhesive. The kinetic energy is used to slit the OCA optical adhesive, providing a basic slitting action for subsequent anti-adhesion measures. While the cutting tool 3 rotates, the cooling shaft 4, rotating on one side of the cutting tool 3, rotates synchronously with it. Two cooling pipes 5 fixed inside the cooling shaft 4 are filled with cooling medium. A pump 6 fixed to the wall of the cooling pipes 5 is activated, driving the cooling medium to circulate between the cooling pipes 5 and multiple cooling channels 7 fixed inside the cutting tool 3. This removes the localized heat generated during high-speed slitting by the cutting tool 3. Simultaneously, a temperature control pad 11 fixed to the inner wall of the cooling pipes 5 adjusts the temperature of the cooling medium in real time, ensuring that the cooling medium remains within the temperature range suitable for the characteristics of the OCA optical adhesive. This prevents the adhesion between the OCA adhesive layer and the cutting tool from being aggravated by increased blade temperature. To suppress residual adhesive formation, the sealing ring 15 fixed to the outer wall of the cooling channel 7 prevents leakage of the cooling medium during circulation, ensuring the continuous and stable operation of the cooling system. The support plate 8 fixed to the top of the mounting base 1 provides stable support for the air duct 9. The air duct 10 fixed to the top of the air duct 9 delivers anti-sticking airflow into the air duct 9. The baffle 14 fixed to the inner wall of the air duct 9 guides and diverts the airflow, avoiding excessively strong or weak airflow in certain areas. This ensures that the airflow is evenly distributed within the air duct 9 and directed towards the cutting contact area between the cutting tool 3 and the OCA optical adhesive. On the one hand, this blows away the tiny adhesive particles generated during the cutting process; on the other hand, it forms an airflow barrier on the surface of the blade, reducing direct contact between the OCA adhesive layer and the blade surface, further assisting in suppressing residual adhesive adhesion. During device operation, the optical sensor 12, fixed to the inner wall of the support plate 8, continuously collects surface image signals of the cutting edge and side of the cutting tool 3 and transmits the signals to the signal processing module 13. The signal processing module 13 analyzes the image signals to determine whether there is residual adhesive on the blade surface and the amount of residual adhesive. If a trend of residual adhesive accumulation is detected, timely feedback can be provided to remind subsequent maintenance, preventing residual adhesive from affecting subsequent cutting accuracy and ensuring the continuity and stability of the cutting process. The wear-resistant layer 16 fixedly coated on the outer side of the cutting tool 3 enhances the wear resistance of the tool surface, preventing the cutting edge of the cutting tool 3 from deforming or its anti-sticking ability from decreasing due to wear during long-term cutting operations, extending the service life of the cutting tool 3, and ensuring that the tool always maintains good cutting and anti-sticking performance.Reduce slitting quality fluctuations caused by tool wear.

[0021] For easier temperature control, such as Figure 1-2 As shown, temperature control pads 11 are fixedly installed on the inner walls of the two cooling pipes 5.

[0022] For ease of monitoring, such as Figure 1 As shown, an optical sensor 12 and a signal processing module 13 are fixedly mounted on the inner wall of the support plate 8.

[0023] To ensure more even airflow, such as Figure 3 As shown, a partition 14 is fixedly installed on the inner wall of the air duct 9.

[0024] Finally, for better sealing, such as Figure 1 As shown, a sealing ring 15 is fixedly provided on the outer wall of the cooling channel 7, and a wear-resistant layer 16 is fixedly coated on the outer side of the cutting tool 3.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
