Description

Technical Field

[0001] This utility model relates to the field of screen manufacturing technology, specifically to a screen conveyor belt that can eliminate static electricity. Background Technology

[0002] Because LCD screens are not very resistant to static electricity, companies are increasingly demanding stricter requirements for static elimination during LCD screen cleaning. Firstly, static electricity should be minimized during production and use to prevent damage to the LCD screen during transportation, cleaning, and installation. Secondly, in production and transportation workshops, operators wear anti-static clothing and shoes, and discharge static electricity before entering the work area to prevent pre-existing static electricity on their bodies or generated during movement. Furthermore, maintaining a suitable temperature and humidity in the production area helps create a conductive environment where air acts as a discharge medium, ensuring timely and effective release of static electricity and preventing its accumulation.

[0003] However, in production and transportation workshops, LCD screens are transported using several conveyor shafts. These shafts are fixed to the frame by bearings, and rollers are installed on the shafts. When the conveyor shafts are in contact with the LCD screens, the oil film formed by the lubricating grease as the bearings rotate can hinder the conduction of the circuit, causing static electricity accumulation. This can lead to damage to the LCD screen due to electrostatic discharge. Therefore, this invention provides a screen conveyor belt that can eliminate static electricity. Summary of the Invention

[0004] This invention provides a screen conveyor belt that can eliminate static electricity, thereby solving the problems mentioned in the background art.

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

[0006] A static-eliminating screen conveyor belt includes a support frame and a plurality of roller assemblies arranged side by side on the support frame. Each roller assembly includes a metal roller and a connecting terminal. The metal roller is rotatably mounted on the support frame via a bearing structure. The connecting terminal is fixedly connected to the support frame and makes point contact or line contact with the metal roller through a contact portion.

[0007] Furthermore, the contact portion is spherically shaped.

[0008] Furthermore, the connecting terminal is composed of a body and an elastic arm, the elastic arm being integrally formed at one end of the body, and the end of the elastic arm away from the body being bent inward to form the contact portion.

[0009] Furthermore, the middle part of the elastic arm is bent inward to form a retractable elastic section.

[0010] Furthermore, two elastic arms are symmetrically arranged.

[0011] Furthermore, the connecting terminal is fixedly installed below the metal roller via a connecting assembly.

[0012] Furthermore, the connecting component includes a positioning element and a fixing screw. The bearing frame is provided with a foolproof locking position. The two ends of the positioning element are respectively engaged with the foolproof locking position and the connecting terminal. The foolproof locking position is provided with a threaded hole for threaded engagement with the fixing screw.

[0013] This invention uses point or line contact between the connecting terminal and the contact part of the metal roller to conduct the static electricity accumulated on the metal roller to the ground in a timely manner, effectively avoiding the accumulation of static electricity and thus protecting the LCD screen from electrostatic discharge damage.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0022] In this embodiment, refer to Figure 1 - Figure 4The specific implementation of a screen conveyor belt that can eliminate static electricity includes a support frame 1 and a plurality of roller assemblies arranged side by side on the support frame 1. The roller assembly includes a metal roller 2 and a connecting terminal 3. The metal roller 2 is rotatably mounted on the support frame 1 through a bearing structure 4. The connecting terminal 3 is fixedly connected to the support frame 1. The connecting terminal 3 makes point contact or line contact with the metal roller 2 through a contact part 303.

[0023] like Figure 2-4 As shown, the contact portion 303 is spherically shaped, which effectively improves the stability of the contact and ensures the electrostatic conduction efficiency. Furthermore, by adjusting the material and hardness of the contact portion 303, its contact effect with the metal roller 2 can be further optimized, reducing wear and extending its service life.

[0024] Furthermore, the connecting terminal 3 is fixedly installed below the metal roller 2 via a connecting assembly to prevent the connecting terminal 3 from interfering with the conveying of the metal roller 2 and to ensure a smooth conveying process.

[0025] Furthermore, the bearing structure 4 consists of a bearing housing and a bearing. The bearings are respectively fitted onto both ends of the metal roller 2 and are rotatably fixed to the bearing housing via the bearings.

[0026] Furthermore, the connecting assembly includes a positioning element 5 and a fixing screw 6. The supporting frame 1 is provided with a foolproof locking position 101. Both ends of the positioning element 5 are respectively engaged with the foolproof locking position 101 and the connecting terminal 3. The foolproof locking position 101 has a threaded hole for threaded engagement with the fixing screw 6. The fixing screw 6 securely locks the connecting terminal 3, ensuring that the connecting terminal 3 does not shift during high-speed operation, further improving the stability and safety of the overall structure. The design of the foolproof locking position 101 effectively prevents installation errors and improves assembly efficiency. The precise engagement of the threaded hole ensures that the fixing screw 6 is reliably tightened, preventing loosening. The overall structure is compact, easy to maintain, suitable for various working conditions, and significantly improves production efficiency.

[0027] This invention enables point or line contact between the connecting terminal 3 and the contact portion 303 of the metal roller 2, thereby timely conducting the static electricity accumulated on the metal roller 2 to the ground, effectively avoiding the accumulation of static electricity and protecting the LCD screen from electrostatic discharge damage. Example

[0028] like Figure 5As shown, the connecting terminal 3 consists of a main body 301 and an elastic arm 302. The elastic arm 302 is integrally formed at one end of the main body 301. The end of the elastic arm 302 away from the main body 301 is bent inward to form the contact portion 303, and the middle portion of the elastic arm 302 is bent inward to form a retractable elastic portion. The design of the elastic arm 302 allows the contact portion 303 to adapt to the slight deformation of the metal roller 2 and maintain a stable contact state. In addition, the inward bending of the middle portion of the elastic arm 302 to form a retractable elastic portion further enhances the stability and reliability of the connection. Example

[0029] like Figure 6 As shown, there are two symmetrically arranged elastic arms 302. The two symmetrically arranged elastic arms 302 make the contact between the connecting terminal 3 and the metal roller 2 more stable and less likely to fall off. At the same time, it improves the vibration resistance of the overall structure, ensures that it can maintain excellent electrostatic conductivity during high-speed operation, and extends the service life of the equipment.
