[0002] Static electricity is a common natural phenomenon, which is generated due to the unbalanced charges on the surface of an object.

[0036] In order to thoroughly understand the present utility model, detailed structures and steps will be presented in the following description to explain the technical solutions proposed by the present utility model. The preferred embodiments of the present utility model are described in detail as follows. However, in addition to these detailed descriptions, the present utility model can also have other implementation manners.

[0037] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the disclosure pertains. It will be further understood that the terms used herein should be interpreted as having a meaning consistent with their meaning in the context of this specification and the relevant art, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0038] In order to illustrate the technical solutions of the present application, specific embodiments will be used for illustration below.

[0039] In the first embodiment, as Figure 1 and Figure 2 shown, a structural schematic diagram of an electrostatic eliminator is provided. The electrostatic eliminator includes: a discharger and N discharge needles 12. The two ends of the discharger are connected to a power supply. A discharge plane 11 is provided between the two ends of the discharger. All the discharge needles 12 are arranged staggeredly on the discharge plane 11. The needle tips 121 of all the discharge needles 12 face the opposite direction of the discharge plane 11. The discharge plane 11 is in communication with the discharge needles 12 so that the needle tips 121 of the discharge needles 12 generate charges.

[0040] For example, the above electrostatic eliminator can be an electrostatic elimination bar, which is in a rod shape. The electrostatic elimination bar can be cylindrical, square-columnar, etc. Among them, if the electrostatic elimination bar is square-columnar, the plane for installing the discharge needles 12 is the discharge plane 11. If the electrostatic elimination bar is cylindrical, the fan surface for installing the discharge needles 12 can be used as the discharge plane 11. Of course, the electrostatic elimination bar can also be in other special-shaped rod structures as long as the structural requirements of the present application are met, and details will not be elaborated here.

[0041] In the above static eliminator, the discharger is used to connect to a power supply. A discharge plane 11 is provided between the two ends of the discharger. The discharge plane 11 is a working plane that can provide the function of eliminating static electricity. A plurality of discharge needles 12 are provided on the discharge plane 11. The number of discharge needles 12 can be determined according to the length of the discharge plane 11. It should be understood that the discharge needles 12 are arranged in a staggered pattern on the discharge plane 11. The longer the discharge plane 11, the more discharge needles 12 can be arranged. For example, when the length of the discharge plane 11 is 350 mm, 5 discharge needles 12 can be provided; when the discharge plane 11 is 400 mm, 6 discharge needles 12 can be provided. The length of the discharge plane 11 can be customized to meet the needs of industrial production.

[0042] In the above static eliminator, the power supply applies a voltage to the tip 121 of the discharge needle 12, causing a corona discharge phenomenon at the discharge needle 12. When a corona discharge occurs, the air around the discharge needle 12 becomes ionized and is ejected onto the surface of the object on the production line, offsetting the charge accumulated on the object surface and neutralizing the surface static electricity to achieve the effect of static elimination. The direction of the tip 121 of the discharge needle 12 points in the opposite direction of the discharge plane 11. It should be understood that the tip 121 faces the outside of the static eliminator. During operation, the discharge plane 11 is parallel to the assembly line plane, and the tip 121 of the discharge needle 12 points in the direction of the assembly line plane.

[0043] In the above static eliminator, the discharge needles 12 are arranged in a staggered pattern on the discharge plane 11. The schematic diagram of the bottom structure of the static eliminator is as Figure 1 shown. The discharge needles 12 are evenly distributed on both sides of the central axis of the discharge plane 11, and the distance between adjacent two discharge needles 12 is the same. The schematic diagram of the front structure of the static eliminator is as Figure 2 shown. The discharge needles 12 are equally spaced in the horizontal direction.

[0044] In an embodiment of the present application, a static eliminator with the discharge needles 12 arranged in a staggered pattern has an increased cross-sectional area of the ion beam radiation region, enabling a larger area of the production assembly line to be covered. It can transmit ion beams over a relatively long distance, allowing the static eliminator to be applied to a larger space and cover a larger area, effectively eliminating the impact of static electricity on the entire area. It can also process multiple devices or regions simultaneously, improving work efficiency.

[0045] In the second embodiment, as Figures 3 to 4 shown, a schematic diagram of the structure of a static eliminator is provided. Any discharge needle 12 further includes a needle base 122. The needle base 122 is installed on the discharge plane 11, and the tip 121 is rotatably installed on the needle base 122; the tip 121 rotates in a plane perpendicular to the discharge plane 11, starting from the angle where the tip is perpendicular to the discharge plane 11, and the range of the rotation angle is 0° to 60°.

[0046] Specifically, the discharge needle 12 includes a needle tip 121 and a needle base 122. The needle base 122 is the base for mounting the needle tip 121, which is used to stabilize the position of the needle tip 121 and protect the needle tip 121 from being damaged by external forces. The needle tip 121 can rotate in a plane perpendicular to the discharge plane 11 through an axis, and the injection direction of the ion beam can be adjusted by controlling the rotation of the needle tip 121.

[0047] Furthermore, the needle tip 121 can rotate a preset angle θ in a plane perpendicular to the discharge plane 11. The preset angle θ is a rotatable angle that can be set. For example, when the preset angle θ is set to 120°, the needle tip 121 can start from the position where the needle is perpendicular to the discharge plane and rotate freely within the range of 0° to 60°.

[0048] An electrostatic elimination device according to this embodiment is provided with a rotatable needle tip 121, which can control the injection direction of the ion beam, increase the area covered by the ion beam, improve the effect of electrostatic elimination, and improve work efficiency.

[0049] In Embodiment 3, as Figure 5 shown, a structural schematic diagram of an electrostatic elimination device is provided, and any three adjacent discharge needles 12 are arranged in a triangular pattern.

[0050] Specifically, three adjacent discharge needles 12 are distributed in a triangular pattern to ensure that the discharge needles 12 are evenly distributed on both sides of the midline of the discharge plane 11. Among them, the triangle can be an obtuse triangle, an acute triangle, or a right triangle.

[0051] An electrostatic elimination device according to this embodiment distributes the discharge needles 12 on both sides of the midline of the discharge plane 11, improves the discharge efficiency and uniformity, increases the width covered by the ion beam, and improves the effect of electrostatic elimination.

[0052] In an implementation manner, an electrostatic elimination device is provided, and the power supply voltage range is 110 volts to 240 volts of alternating current.

[0053] Both ends of the discharger are connected to a power supply. When alternating current is provided, the voltage range can be 100 volts to 240 volts. When direct current is provided, the voltage range can be 22 volts to 26 volts.

[0054] An electrostatic elimination device according to this embodiment provides a power supply voltage range, enabling the electrostatic elimination device to be used normally in different current environments, meeting the actual power consumption requirements, and facilitating the implementation of electrostatic elimination work.

[0055] In Embodiment 4, as Figure 6As shown in the figure, a substrate film laminating production line is provided. The substrate film laminating production line includes: a pre-treatment feeding conveyor, a buffer machine, a dust sticking machine, a pre-heater, a film laminating machine, a post-pressing machine, and a board collecting machine. An electrostatic eliminator is respectively arranged at the inlet and outlet of the dust sticking machine, an electrostatic eliminator is respectively arranged at the inlet and outlet of the film laminating machine, or an electrostatic eliminator is respectively arranged at the inlet and outlet of the post-pressing machine. Of course, electrostatic eliminators can be simultaneously arranged on the above-mentioned dust sticking machine, film laminating machine, post-pressing machine, etc., or electrostatic eliminators can be simultaneously arranged on the dust sticking machine and the film laminating machine, while no electrostatic eliminator is arranged at the post-pressing machine, or electrostatic eliminators are simultaneously arranged on the film laminating machine and the post-pressing machine, while no electrostatic eliminator is arranged at the dust sticking machine. That is, the number and position of the electrostatic eliminators are set according to requirements, which will not be elaborated here.

[0056] The electrostatic eliminator includes: a discharger, with both ends of the discharger connected to a power supply, and a discharge plane 11 is arranged between both ends of the discharger; and N discharge needles 12, all the discharge needles 12 are arranged staggeredly on the discharge plane 11, the needle tips 121 of all the discharge needles 12 face the opposite direction of the discharge plane 11, and the discharge plane 11 is communicated with the discharge needles 12 so that the needle tips 121 of the discharge needles 12 generate electric charges.

[0057] In the above-mentioned substrate film laminating production line, the specific steps required for substrate film laminating are given. Specifically, the substrate is input into the conveyor, and after simple sorting, it is transmitted to the buffer machine to balance the running speeds of the front and rear machines. The sorted substrate is transmitted to the dust sticking machine at a certain rate. After the dust on the substrate surface is removed by the dust sticking roller, it is transmitted to the pre-heater for heating up, then conveyed to the film laminating machine to attach the film to the substrate surface, and then sent to the post-pressing machine to be compacted by the pressing roller. Finally, the substrate with the film laminated is sent to the board collecting machine for recycling. When the substrate passes through the dust sticking roller of the dust sticking machine, static electricity will be generated due to the contact friction between the substrate and the dust sticking roller. Therefore, the electrostatic eliminator described in Embodiment 1 is installed at the inlet and outlet of the dust sticking machine, and the discharge needles 12 face the inlet and outlet of the dust sticking machine to eliminate the static electricity on the surface of the substrate on the conveyor belt and prevent the substrate from adsorbing dust due to static electricity, which may affect the product quality. Similarly, when the substrate passes through the film laminating machine and the post-pressing machine, some static electricity will be generated due to friction. Electrostatic eliminators can be installed before and after the process steps where static electricity is likely to be generated to eliminate static electricity in time or avoid the generation of static electricity.

[0058] In the above-mentioned substrate film laminating production line, the discharger of the electrostatic eliminator is used to connect to the power supply for power supply, and a discharge plane 11 for releasing electric charges to eliminate static electricity is arranged between both ends of the discharger. The discharge needles 12 are installed on the discharge plane 11. When the substrate film laminating production line is running, the discharge needles 12 face the production line, and a corona discharge phenomenon occurs under the action of the power supply. The air near the discharge needles 12 becomes ions and is sprayed onto the substrate surface to neutralize the static electricity on the substrate surface.

[0059] The substrate film laminating production line of this embodiment provides a process for substrate film lamination. Static electricity is eliminated by a static eliminator before and after operations prone to generating static electricity, effectively avoiding the reduction of substrate quality caused by static electricity problems, improving the qualification rate of substrate film lamination, and increasing the output of substrate film lamination.

[0060] The above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention, and should all be included in the protection scope of the present invention.
