Description

Technical Field

[0001] This utility model belongs to the field of display screen manufacturing, and specifically relates to a grounding base used in display screen manufacturing. Background Technology

[0002] In the display manufacturing industry, electrostatic discharge (ESD) control is a core aspect of ensuring product quality. Because the core components of displays are extremely sensitive to static electricity, even a small amount of static buildup can cause component damage or abnormal display functionality. Therefore, strict control of static electricity is necessary throughout the entire production process. In most processes, specialized devices are required to promptly discharge static electricity to prevent it from affecting production.

[0003] Some of the production equipment includes rotating shaft structures. The static discharge requirements of these dynamic components face special challenges. Static discharge needs to be achieved through grounding. However, the design logic of existing grounding sockets is generally based on static scenarios, relying on wires to be directly connected to fixed equipment to complete the grounding loop.

[0004] Since the rotating shaft is in a continuous state of rotation, if the traditional static grounding solution is used, the wire will become entangled and pulled as the shaft rotates, and may even wear and break due to long-term friction. Not only will it be impossible to stably discharge static electricity, but it may also cause equipment failure due to wire damage, which will increase production risks.

[0005] Currently, there is no mature and reliable electrostatic discharge grounding solution for structures in this rotating state. How to construct a stable and safe electrostatic grounding path without affecting the normal operation of the rotating shaft has become a technical pain point that urgently needs to be overcome in the display screen production process, and it also puts forward higher requirements for the innovation of electrostatic control solutions.

[0027] Figure 2 This is a schematic diagram of the exploded structure of this embodiment;

[0028] The components include: body 1, groove 1a, screw 1b, compression spring 2, carbon rod 3, protrusion 3a, connecting shaft 4, blocking part 4a, first bearing 5, grounding wire 6, rotating shaft 7, second bearing 8, base 9, flat pad 10, spring pad 11, and end cap 12. Detailed Implementation

[0029] like Figure 1 , 2 As shown, this embodiment includes a conductor body 1, a compression spring 2, a carbon rod 3, a connecting shaft 4, a first bearing 5, and a grounding wire 6.

[0030] One end of the main body 1 is connected to the connecting shaft 4. Specifically, a screw 1b is provided at one end of the main body 1, and the end face of the rotating shaft 7 is provided with a first threaded hole corresponding to the screw 1b. The screw 1b is threadedly connected to the first threaded hole to realize the connection between the main body 1 and the rotating shaft 7.

[0031] A groove 1a is provided on the other end face of the main body 1.

[0032] A compression spring 2 is placed inside a groove 1a, with one end of the compression spring 2 abutting against the bottom of the groove 1a.

[0033] A carbon rod 3 is also disposed within the groove 1a, abutting against the other end of the compression spring 2. In this embodiment, a protrusion 3a is also provided on the surface of the carbon rod 3 that contacts the compression spring 2. The protrusion 3a is inserted into the end of the compression spring 2, which not only prevents the carbon rod 3 from detaching from the compression spring 2 but also enhances its conductivity. In other embodiments, the carbon rod 3 can be replaced by a carbon block.

[0034] The first bearing 5 is also located in the groove 1a.

[0035] This embodiment also includes an end cap 12, which covers the end face of the groove 1a and seals the first bearing 5 inside the groove 1a.

[0036] One end of the connecting shaft 4 abuts against the carbon rod 3, and the other end passes through the first bearing 5 and the end cap 12, extending out of the body 1 from the first bearing 5 and the end cap 12. In this embodiment, a blocking part 4a is also provided on the side wall of the connecting shaft 4 located between the first bearing 5 and the carbon rod 3 to prevent the connecting shaft 4 from being easily pulled out of the body 1.

[0037] In this embodiment, the surface of the carbon rod 3 that contacts the connecting shaft 4 is smooth, while the surface of the connecting shaft 4 that contacts the carbon rod 3 is conical. In other embodiments, the surface of the connecting shaft 4 that contacts the carbon rod 3 can also be spherical. With this structure, the frictional force can be reduced when the connecting shaft 4 rotates relative to the carbon rod 3.

[0038] One end of the grounding wire 6 is grounded, and the other end is connected to the other end of the connecting shaft 4. Specifically, a second threaded hole is provided on the end face of the other end of the connecting shaft 4. A bolt is then installed, which passes through the other end of the grounding wire 6 and is threaded into the second threaded hole and tightened, thus fixing the other end of the grounding wire 6 to the connecting shaft 4.

[0039] Furthermore, in order to improve the firmness of the connection between the grounding wire 6 and the connecting shaft 4, flat washers 10 and spring washers 11 are also fitted onto the bolts.

[0040] This embodiment also includes a second bearing 8 and a base 9.

[0041] The second bearing 8 is sleeved on the end of the rotating shaft 7, and the base 9 is used to support the second bearing 8.

[0042] In this embodiment, when the rotating shaft 7 rotates, it drives the main body 1 to rotate. Since one end of the connecting shaft 4 abuts against the carbon rod 3 and has a small contact surface with it, and the other end of the connecting shaft 4 is pulled by the grounding wire 6, and a first bearing 5 is provided between the connecting shaft 4 and the main body 1, the connecting shaft 4 does not rotate when the main body 1 rotates. Furthermore, due to the action of the compression spring 2, the connecting shaft 4 maintains good contact with the main body 1. Ultimately, this embodiment possesses both good conductivity and does not rotate with the rotating shaft 7.
