Description

Technical Field

[0001] The utility model patent relates to the technical field of dust-free cloths, and mainly relates to a device for changing the wiping shape of a dust-free cloth. Background Art

[0002] The LCD display screen is mainly composed of FPC and IC Bonding. The protection of the Bonding area and terminal circuit is to block the coating colloid. When the needle nozzle coats the colloid on the protection area, there will be colloid residue on the needle wall after coating, which will affect the coating effect of the next product, so the needle nozzle needs to be wiped with a dust-free cloth;

[0003] In the existing wiping process, the dust-free cloth is placed flat, and the wiping action after the needle nozzle coating is completed is that the needle nozzle directly drops, and the needle nozzle pushes the dust-free cloth into a V shape for wiping; during the continuous operation process, it is easy to cause the needle nozzle to deform, reducing the service life of the needle nozzle. In this regard, we propose a device to change the wiping shape of the dust-free cloth. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0024] For example, please refer to Figure 1-4 , a device for changing the wiping form of a dust-free cloth, comprising a bracket 10, the top of the bracket 10 is connected to a dust-free cloth mechanism 40, one side of the top of the bracket 10 is connected to a needle device 20, one side of the top of the bracket 10 is fixed with a C-shaped plate 11, the top of the C-shaped plate 11 is connected to a pressing device 30, the pressing device 30 comprises a threaded rod 31 connected to one side of the C-shaped plate 11, a fixed block 32 rotatably connected to the bottom of the threaded rod 31 and a pressing block 33 connected to the bottom of the fixed block 32, the bottom of the pressing block 33 is triangular, and the angle between the two side surfaces of the bottom of the pressing block 33 is 45°;

[0025] Both sides of the top of the threaded rod 31 are connected to buffer springs 34 , and the bottom of the buffer spring 34 is connected to a buffer plate 35 .

[0026] It should be noted that, in the embodiment, the threaded rod 31 is rotated to drive the fixed block 32 and the pressing block 33 to descend, and when the buffer plate 35 contacts the C-shaped plate 11, the descent stops, and the buffer spring 34 plays a buffering role;

[0027] Furthermore, the device is designed with bakelite, which is anti-static, wear-resistant and high-temperature resistant.

[0028] For example, please refer to Figure 2-3 The dust-free cloth mechanism 40 includes a rotating column 41 rotatably connected to both sides of the bracket 10 , a torsion spring 42 sleeved on both sides of the rotating column 41 , and a dust-free cloth 43 connected to the top of the rotating column 41 .

[0029] It should be noted that, in the embodiment, the pressing block 33 descends to contact the dust-free cloth 43. Since the angle between the two side surfaces of the bottom of the pressing block 33 is 45°, the dust-free cloth 43 is V-shaped. During this process, the rotating column 41 is driven to rotate by the dust-free cloth 43, so that the torsion spring 42 generates an elastic force. When the pressing block 33 rises, the rotating column 41 is rotated by the elastic force of the torsion spring 42, and the dust-free cloth 43 is restored.

[0030] For example, please refer to Figure 2T-shaped support blocks 13 are installed on both sides of the top of the bracket 10. A bevel 131 is provided on one side of the top of the T-shaped support block 13. One side of the bevel 131 is rotatably connected to a roller 132.

[0031] It should be noted that, in the embodiment, the bevel 131 reduces the friction between the dust-free cloth 43 and the T-shaped support block 13 , and the roller 132 further reduces the wear of the dust-free cloth 43 .

[0032] For example, please refer to Figure 4 A limiting block 311 is fixed at the bottom of the threaded rod 31;

[0033] A cavity 321 is disposed on the top of the fixing block 32 , and the cavity 321 is connected to the limiting block 311 .

[0034] It should be noted that, in the embodiment, the limit block 311 is used to limit the position of the fixing block 32 .

[0035] For example, please refer to Figure 4 The top of the limit block 311 is rotatably connected to a plurality of rollers 312 formed in an array.

[0036] It should be noted that, in the embodiment, the roller 312 reduces the friction between the limiting block 311 and the fixing block 32 , thereby facilitating the rotation of the limiting block 311 .

[0037] For example, please refer to Figure 2-3 , L-shaped rods 331 are fixed on both sides of the pressing block 33;

[0038] Rectangular sliding grooves 12 are provided on both sides of the bracket 10 , and the groove bodies of the rectangular sliding grooves 12 are slidably connected to the L-shaped rods 331 .

[0039] It should be noted that, in the embodiment, the rectangular slide groove 12 limits the rotation of the pressing block 33 .

[0040] For example, please refer to Figure 2 A rotating handle 313 is installed on the top of the threaded rod 31.

[0041] It should be noted that, in the embodiment, the rotating handle 313 facilitates the rotation of the threaded rod 31 .

[0042] The specific operation mode of the utility model is as follows:

[0043] The above-mentioned device for changing the wiping shape of the dust-free cloth first drives the fixed block 32 and the pressing block 33 to descend by rotating the threaded rod 31. When the buffer plate 35 contacts the C-shaped plate 11, the pressing block 33 stops descending, and the buffer spring 34 plays a buffering role. During the descent, the pressing block 33 contacts the dust-free cloth 43. Since the angle between the two side surfaces of the bottom of the pressing block 33 is 45°, the pressed dust-free cloth 43 is V-shaped. At the same time, the dust-free cloth 43 drives the rotating column 41 to rotate, so that the torsion spring 42 generates elastic force to prevent the dust-free cloth 43 from being broken due to excessive tension. When the pressing block 33 rises, the elastic force of the torsion spring 42 causes the rotating column 41 to rotate, and the dust-free cloth 43 is restored.

[0044] The above-described embodiments only express the implementation methods of the present application, but for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
