Description

Technical Field

[0001] This utility model belongs to the field of display screen manufacturing, and specifically relates to a device for reducing particles generated by friction between connecting rods and bolts. Background Technology

[0002] In the display screen manufacturing system, the support device used to hold the display screen substrate plays a crucial role, and its stable operation is directly related to the orderly progress of production. However, in the process of fixing the display screen substrate, adjusting the connecting rods on the support device is an essential step, but this adjustment process harbors potential risks that may affect product quality.

[0003] Both the connecting rod and the frame are made of metal, which inherently possesses a certain degree of hardness and wear resistance. However, when adjusting the connecting rod, contact and relative movement between the two are inevitable, resulting in friction. This friction is not a simple surface contact; the microscopic unevenness of the metal surface leads to mutual scraping and grinding, generating a large number of tiny particles that are not directly observable to the naked eye. These particles are extremely small, often existing at the micrometer or even nanometer scale, allowing them to easily disperse in the production environment.

[0004] More importantly, friction also occurs between the connecting rod and the bolt during the fixing process. The connection between the bolt and the connecting rod requires rotation to tighten, and the interaction between the metal bolt and the connecting rod in this process generates new fine particles. These particles mix with the previously generated particles, forming a potential source of pollution.

[0005] When these tiny particles settle onto the display substrate, their harmful effects become apparent. The circuitry on the display substrate is extremely precise, with complex circuit layouts and minute spacing; even the smallest impurities can have a serious impact. Particles adhering to the circuit surface can cause short circuits, disrupting normal current paths; they can also block circuit connections, causing open circuits. Both short circuits and open circuits directly affect the normal function of the display, leading to display abnormalities, performance degradation, and other problems.

[0006] As these problems emerge, the number of defective displays in the final product shipment increases significantly, directly leading to a decrease in the yield rate. This not only increases production costs, including waste of raw materials and lost production time, but also affects the company's production efficiency and market competitiveness, causing unnecessary economic losses. Utility Model Content

[0007] This invention provides a device for reducing the particles generated by friction between connecting rods and bolts, which can effectively solve the problems in the background art.

[0008] This utility model provides a device for reducing particles generated by friction between connecting rods and bolts, comprising:

[0009] link;

[0010] Frame;

[0011] Insulating pads that isolate the connecting rod from the frame;

[0012] Bolts that pass through the connecting rod, washer, and frame in sequence and are fastened together by nuts;

[0013] And, an insulating material that separates the bolt head from the connecting rod.

[0014] As a further optimization of this utility model, one end of the connecting rod is provided with an oval stepped hole through which the bolt thread passes; the isolation member is barrel-shaped and has a through hole at the bottom. After the bolt thread passes through the through hole, the bolt head is covered by the isolation member, and the isolation member is embedded in the large-size part of the oval stepped hole.

[0015] As a further optimization of this utility model, the outer wall dimension of the bolt head corresponds to the width of the large dimension of the oval stepped hole, so that the bolt cannot wobble in the width direction of the large dimension of the oval stepped hole.

[0016] As a further optimization of this utility model, the frame is provided with a groove corresponding to the shape of one end of the connecting rod, and one end of the connecting rod is embedded in the groove.

[0017] As a further optimization of this utility model, the frame is provided with irregular stepped holes, the large part of the irregular stepped holes is rectangular, and the small part of the irregular stepped holes is circular;

[0018] The bolt is a special-shaped bolt. The bolt head of the special-shaped bolt has a cut surface on the side wall near the screw to form a cut surface. The middle side wall of the bolt head of the special-shaped bolt has a groove.

[0019] The position of the cut surface corresponds to the large part of the irregular stepped hole, and the arc surface of the cut surface just abuts against the side wall of the large part of the irregular stepped hole.

[0020] As a further optimization of this utility model, the bolt head of the irregular bolt has two opposing cut surfaces near the side wall of the screw to form a cut surface.

[0021] As a further optimization of this utility model, the gasket and the separator are made of PI resin.

[0022] This utility model provides a device for reducing the generation of particles caused by friction between connecting rods and bolts.

[0030] Among them, there are: connecting rod 1, oblong stepped hole 1a, large-size part of oblong stepped hole 1a1, small-size part of oblong stepped hole 1a2, frame 2, groove 2a, irregular stepped hole 2b, large-size part of irregular stepped hole 2b1, small-size part of irregular stepped hole 2b2, gasket 3, spacer 4, through hole 4a, irregular bolt 5, bolt head 5a, cut surface 5a1, groove 5a2, screw 5b, and nut 6. Detailed Implementation

[0031] like Figure 1 As shown, the device in this embodiment is used as a display substrate support device. This device typically includes a frame-shaped frame 2 and a connecting rod 1 fixed to the frame 2. When installing the display substrate, the connecting rod 1 needs to be finely adjusted relative to the frame 2 before being fixed. Friction can easily occur between the connecting rod 1 and the frame 2 when fixing the connecting rod 1 to the frame 2 and when finely adjusting the connecting rod 1, generating tiny particles that affect the yield of the display substrate.

[0032] like Figure 2-7 As shown, this embodiment includes a connecting rod 1, a frame 2, a gasket 3, bolts, and a spacer 4.

[0033] To facilitate the installation of the display substrate and ensure flatness, this embodiment provides a recessed groove 2a on the frame 2 that corresponds to the shape of one end of the connecting rod 1. Since one end of the connecting rod 1 is strip-shaped, the recessed groove 2a is also strip-shaped and its length direction is consistent with the length direction of the connecting rod 1. The width of the recessed groove 2a is slightly larger than the width of one end of the connecting rod 1, so that one end of the connecting rod 1 can be embedded in the recessed groove 2a. The recessed groove 2a also prevents the connecting rod 1 from rotating relative to the frame 2, reducing the possibility of mutual friction.

[0034] The gasket 3 is located between the connecting rod 1 and the frame 2. The gasket 3 isolates the contact surfaces of the two. The gasket 3 is made of insulating material, specifically PI resin material.

[0035] Bolts pass through connecting rod 1, washer 3 and frame 2 in sequence and are fastened together by nuts 6.

[0036] The isolator 4 is also made of insulating material, specifically PI resin material. The isolator 4 is located between the bolt head 5a and the connecting rod 1 to isolate the two.

[0037] Specifically, in this embodiment, a stepped oblong hole 1a is provided at one end of the connecting rod 1 for the threaded rod 5b of the bolt to pass through. Since the connecting rod 1 is adjusted along its length in this embodiment, the length direction of the stepped oblong hole 1a is consistent with the length direction of the connecting rod 1. In other embodiments, if the connecting rod 1 is adjusted along a direction perpendicular to its length, the length direction of the stepped oblong hole 1a can be set to be perpendicular to the length direction of the connecting rod 1.

[0038] In this embodiment, the isolation member 4 is made into a barrel shape, and a through hole 4a is provided at the bottom of the isolation member 4. After the bolt shank 5b passes through the through hole 4a, its bolt head 5a is covered by the isolation member 4. The height of the isolation member 4 is not higher than the depth of the large size part 1a1 of the oval stepped hole. Therefore, the isolation member 4 can be embedded in the large size part 1a1 of the oval stepped hole.

[0039] In this embodiment, the outer wall of the bolt head 5a is made into a shape that corresponds to the width of the large size portion 1a1 of the oval stepped hole, so that the bolt head 5a is exactly located in the large size portion 1a1 of the oval stepped hole, so that the bolt cannot wobble in the width direction of the large size portion 1a1 of the oval stepped hole, which also reduces the possibility of friction.

[0040] Preferably, the bolt in this embodiment is a special-shaped bolt 5, which includes a bolt head 5a and a screw 5b. The middle side wall of the bolt head 5a is provided with a groove 5a2, and the lower side wall of the bolt head 5a, that is, the side wall of the bolt head 5a near the screw 5b, is provided with a cut surface to form a cut surface 5a1. Specifically, there are two cut surfaces opposite each other.

[0041] Meanwhile, an irregularly shaped stepped hole 2b is provided on the frame 2. The larger portion 2b1 of the irregularly shaped stepped hole is rectangular, and the smaller portion 2b2 is circular. When the irregularly shaped bolt 5 passes through the irregularly shaped stepped hole 2b, the cut surface 5a1 falls exactly into the larger portion 2b1 of the irregularly shaped stepped hole, and the arc surface of the cut surface 5a1 abuts against the side wall of the larger portion 2b1 of the irregularly shaped stepped hole. This prevents the irregularly shaped bolt 5 from rotating, and at the same time minimizes the contact area between the bolt head 5a side wall and the irregularly shaped stepped hole 2b, reducing the impact of friction.
