[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3This utility model provides a technical solution: a bonding auxiliary device for antistatic release film lamination of sensors, including an auxiliary mechanism 1. The auxiliary mechanism 1 includes an outer box 11, inside which a release film 5 is inserted. The release film 5 is conveyed by a conveying roller (not shown in the figure). The right side of the outer box 11 is connected to the lamination equipment. Inside the outer box 11, there are a first elimination chamber 12, a third elimination chamber 13, and a second elimination chamber 14. Partitions 6 are provided on both sides of the second elimination chamber 14. By setting the partitions 6, the working effect of the ion air bar 24 inside the second elimination chamber 14 can be ensured. The partitions 6 are used to separate the second elimination chamber 14 from the first elimination chamber 12 and the third elimination chamber 13. An opening is provided on the top side of the second elimination chamber 14, and a filter mechanism 3 is provided inside the opening. The filter mechanism 3 serves as the air inlet, while the left and right sides of the outer casing 11 can be used for air outlets. This effectively prevents dust from entering the outer casing 11 during the delivery of the release membrane 5. The filter mechanism 3 of this structure can include components such as filter screens and filter cotton, mainly used for filtering dust in the incoming air and preventing dust from entering the second elimination chamber 14 during airflow. The first elimination chamber 12 and the third elimination chamber 13 are both equipped with electrostatic elimination roller assemblies 4, and the second elimination chamber 14 is equipped with an electrostatic elimination auxiliary assembly 2. The electrostatic elimination roller assembly 4 includes an aluminum roller 41, the outer wall of which is coated with a carbon nanotube coating 43, and the outer wall of the carbon nanotube coating 43 is equipped with a silicone sleeve 42. The outer wall of the silicone sleeve 42 has micropores, and the thickness of the silicone sleeve 42 does not exceed 2mm. This structure allows the silicone sleeve 42 to rub against the release film 5, generating static electricity for easy discharge. The aluminum roller 41 is grounded. The static elimination principle of the static elimination roller assembly 4 is as follows: static electricity is generated by the friction between the release film 5 and the silicone sleeve 42, and the charge is conducted to the ground by the carbon nanotube coating 43 and the aluminum roller 41. Two sets of static elimination roller assemblies 4 are arranged inside each of the first elimination chamber 12 and the third elimination chamber 13. The static elimination roller assemblies 4 are symmetrically distributed about the bisectors of the first and third elimination chambers 12 and 13. This structure allows static elimination during the input and output of the release film 5, improving the static elimination effect. The static elimination auxiliary component 2 includes components located inside the third elimination chamber 13. The ion bar 24 and the electrostatic elimination auxiliary component 2 are each provided at the top and bottom of the second elimination chamber 14. The electrostatic elimination auxiliary component 2 also includes an electric cylinder 23 installed on the outer wall of the outer casing 11. The electric cylinder 23 is controlled by a PLC to ensure the coordinated operation of the electric cylinder 23. One end of the electric cylinder 23 is fixedly connected to the top of the ion bar 24. This structure of the electric cylinder 23 can automatically adjust the height of the ion bar 24 to keep it at the optimal working height. The ion bar 24 is controlled by a PLC. The working principle of the ion bar 24 is corona discharge: there are one or more high-voltage electrodes inside the ion bar. When a sufficient voltage is applied, a corona discharge phenomenon will be generated at the tip of the electrode. This discharge will form a strong electric field around the electrode.Air ionization: Under the influence of a strong electric field, surrounding air molecules are ionized, producing positive and negative ions. Ion wind generation: The generated positive and negative ions are accelerated by the strong electric field near the electrodes and move in opposite directions. Because the ions carry an electric charge, they interact with any nearby object surface and neutralize the static charge there. Simultaneously, the movement of the ions also drives the surrounding airflow, forming what is known as "ion wind." Static electricity neutralization: When the ion wind comes into contact with an object carrying static electricity, it can quickly neutralize the static charge on that object, whether positive or negative. This effectively reduces static electricity accumulation and prevents static electricity from causing fires. To address the dust adsorption issue, a telescopic rod 21 is fixedly connected to the top side of the ion bar 24. A sleeve rod 22 is fitted onto one end of the telescopic rod 21, and one end of the sleeve rod 22 is fixedly connected to the inner wall of the second elimination chamber 14. Both the sleeve rod 22 and the telescopic rod 21 are symmetrically distributed about the bisector of the ion bar 24, forming a telescopic structure. This structure, by using the sleeve rod 22 and the telescopic rod 21, not only allows for height adjustment of the ion bar 24 but also limits its lifting and lowering, improving the stability of the ion bar 24's movement. The ion bar 24 is slidably connected to the third elimination chamber 13.

[0024] Working principle: When using the anti-static release film lamination auxiliary device of this sensor, the release film 5 is first input into the outer box 11. The release film 5 first contacts and rubs against the silicone sleeve 42 on the outer wall of the aluminum roller 41 in the first elimination chamber 12 to perform the first static elimination treatment. As the release film 5 moves, it enters the second elimination chamber 14. Under the action of the ion air bar 24, the remaining static electricity on the surface of the release film 5 is neutralized, thereby preventing dust from adsorbing on the surface of the release film 5. Then, the release film 5 moves into the third elimination chamber 13. The third elimination chamber 13 contacts and rubs against the silicone sleeve 42 on the outer wall of the aluminum roller 41 to perform the third static elimination treatment, thereby ensuring that there is no dust on the surface of the release film 5 during the subsequent lamination process and improving the lamination quality of the release film 5.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
