Description

Technical Field

[0001] The utility model relates to the technical field of PLasma gun tips, in particular to a PLasma gun tip for cleaning ITO terminals used for processing LCD display screens. Background Art

[0002] A PLASMA gun head is a device used to generate plasma. It is commonly used in various industrial applications such as surface treatment, coating, cleaning, and ion implantation. The main function of a PLASMA gun head is to generate plasma by providing energy and gas. It consists of an electrode system and a gas supply system. When a high-voltage current passes through the electrodes, the gas discharges between the electrodes to generate plasma. In the field of LED display processing, most use PLASMA gun heads to clean the ITO terminals of their conductive connections.

[0003] Currently, the existing PLasma gun tip used for cleaning ITO terminals used in LCD display processing is designed with only a single cleaning port, with a diameter of generally 5mm. During the pressurized cleaning process, the force is excessively concentrated, and the static electricity generated cannot be quickly and silently eliminated, causing damage to the weak ITO circuits. As a result, vertical lines, squares and other defects appear in the finished product test, causing the LCD and its accessories to be scrapped, the equipment utilization rate and stability to decrease, and the manufacturing cost to increase. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the utility model provides a PLasma gun head for cleaning ITO terminals used in LCD display processing. It has the advantages of reducing LCD defective scrap losses and accessory material loss rates during the cleaning process, improving equipment utilization rate and production yield, etc. It solves the problem that static electricity cannot be quickly and silently eliminated when the PLasma gun head is used to clean ITO terminals at the current stage, and weak ITO circuits are easily damaged, resulting in scrap, low utilization rate and stability, and increased costs.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PLasma gun head for cleaning ITO terminals used for LCD display screen processing, comprising a connecting assembly, a sealing assembly and a gun nozzle assembly, wherein the connecting assembly comprises a connecting head, an anti-skid layer is fixed on the side of the connecting head, and a mounting interface is provided at one end of the connecting head, a docking interface is provided in the mounting interface, and a connecting interface is provided at the front end, and the connecting head is threadedly connected to the interface of the pipe through the mounting interface at the tail end, thereby achieving the function of connecting the entire gun head to the pipe, and by fixing an anti-skid layer on the side of the connecting head and providing a plurality of anti-skid grooves equidistantly along the length direction of the anti-skid layer, the friction resistance between the hand and the connecting head is increased during installation and removal, and in addition, when the mounting interface is threadedly connected to the outside of the interface of the pipe, the docking interface provided inside is sleeved on the inside of the pipe, thereby achieving a double-layer protection effect;

[0008] The sealing assembly includes a sealing ring that is sleeved between the installation interface and the docking interface. The sealing ring has a certain elasticity. After installation between the pipe and the pipeline, the sealing ring is tightly attached to the pipeline interface, blocking the gap at the connection to prevent gas from leaking out.

[0009] The nozzle assembly includes a first mounting plate connected to an internal thread of the connecting interface, a second mounting plate hinged at one end of the first mounting plate, a nozzle fixed at one end of the second mounting plate, and the first mounting plate and the second mounting plate are hinged on opposite surfaces so that after the first mounting plate is fixed, the second mounting plate can rotate on the first mounting plate. At the same time, a nozzle is installed at the center position of one end of the second mounting plate, and the nozzle realizes the function of concentrating the input gas and spraying it outward on the LCO terminal to clean the terminal.

[0010] As a further improvement to the above solution, a gas transmission groove communicating with the docking interface is provided in the connection interface;

[0011] Through the above technical solution, when the docking interface is sleeved on the inner side of the pipeline, the gas input from the rear end of the pipeline is input into the gas transmission groove from the front end.

[0012] As a further improvement to the above solution, both the first mounting plate and the second mounting plate are provided with gas delivery holes communicating with the nozzle, and the gas delivery holes are communicated with the gas delivery groove;

[0013] Through the above technical solution, after the pipeline inputs gas into the gas delivery groove, the gas enters the nozzle from the gas delivery hole, and according to the closed-end design of the nozzle, the gas is concentrated and then sprayed out.

[0014] As a further improvement to the above solution, a positioning button is fixed to the side of the sealing ring, and a tension spring is sleeved on the side of the positioning button. One end of the positioning button is attached to the side of the sealing ring, and the other end is attached to the installation interface.

[0015] Through the above technical solution, the tension spring has the function of expanding and pushing the sealing ring outward, so that the sealing ring can fit into the interface of the connected pipe and seal the gap at the interface. Under the force of the tension spring pushing the sealing ring, the installed positioning button moves back and forth in the connector, thereby increasing the stability of the movement of the sealing ring.

[0016] As a further improvement to the above solution, a mounting hole is formed on the first mounting plate, a spring rod is fixed in the mounting hole, and a positioning button is sleeved in the mounting hole, and a positioning hole is formed on the second mounting plate, and the positioning button is engaged in the positioning hole;

[0017] Through the above technical solution, the diameter of the side of the positioning button is consistent with the diameter inside the mounting hole, which increases the stability of the positioning button's extension and retraction. At the same time, the spring rod has the function of expanding and pushing the positioning button, so that the front end of the positioning button is engaged in the positioning hole, fixing the first mounting plate and the second mounting plate to prevent rotation.

[0018] As a further improvement to the above solution, a first gas delivery hole is provided on the first mounting plate, and a second gas delivery hole is provided on the second mounting plate, and the first gas delivery hole and the second gas delivery hole are interconnected;

[0019] Through the above technical solution, the positions of the first air hole and the second air hole correspond to each other. By rotating the second mounting plate, the first air hole and the second air hole are aligned, thereby achieving the effect of quickly discharging static electricity. When the air holes are staggered and closed, the air is blocked to prevent external debris from entering the interior, causing dust accumulation for a long time and leading to heating and aging of internal components. Compared with the traditional nozzle 310, the static electricity pressure generated cannot be quickly eliminated within six seconds. However, through the present solution, air holes are opened on the mounting plate, which can control the static electricity pressure to be silently eliminated within six seconds.

[0020] Compared with the prior art, the present invention provides a PLasma gun tip for cleaning ITO terminals used in LCD display processing, which has the following beneficial effects:

[0021] 1. The PLasma gun head for cleaning ITO terminals used in LCD display processing has a first and a second interconnected air supply hole opened on the first mounting plate and the second mounting plate. The air supply hole and the nozzle are interconnected with the connector. During the cleaning process, excess static pressure is dispersed and discharged from the air supply hole, so that the generated static electricity is quickly and silently eliminated, effectively avoiding damage to weak ITO circuits, thereby completely solving the problem of batch defective scrap caused by static damage, reducing the loss of LCD defective scrap and the damage rate of accessories and materials, and improving equipment utilization rate and production yield.

[0022] 2. The PLasma gun head for cleaning ITO terminals used in LCD display processing has a separate design of the connector and the nozzle. A second mounting plate and a first mounting plate are installed on the nozzle. The opposing surfaces of the first mounting plate and the second mounting plate engage with each other. The second mounting plate is fixed to the connector through threads, thereby rotating the second mounting plate so that the air holes opened on the first and second mounting plates correspond to each other to discharge excess static pressure, or after closing, prevent external debris from entering, thereby improving the cleanliness of the air holes, and further improving the internal cleanliness and service life.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1-8 As shown, the PLasma gun head for cleaning ITO terminals for LCD display processing proposed in this embodiment includes a connecting component 1, a sealing component 2 and a gun nozzle component 3, wherein the connecting component 1 includes a connecting head 101, an anti-slip layer 102 is fixed on the side of the connecting head 101, and a mounting interface 103 is provided at one end of the connecting head 101, a docking interface 104 is provided in the mounting interface 103, and a connecting interface 105 is provided at the front end, and the connecting head 101 is threadedly connected to the interface of the pipe through the mounting interface 103 at the tail end, so as to realize the connection between the entire gun head and the pipe, and the anti-slip layer 102 is fixed on the side of the connecting head 101, and a plurality of anti-slip grooves are equidistantly provided on the anti-slip layer 102 along its length direction, thereby increasing the friction resistance between the hand and the connecting head during installation and disassembly. In addition, when the mounting interface 103 is threadedly connected to the outside of the interface of the pipe, the docking interface 104 provided inside is sleeved on the inside of the pipe, thereby realizing a double-layer protection effect;

[0038] The sealing assembly 2 includes a sealing ring 201 that is sleeved between the installation interface 103 and the docking interface 104. The sealing ring has a certain elasticity. After installation between the pipe and the pipeline, the sealing ring 201 is tightly attached to the pipeline interface, blocking the gap at the connection to prevent gas from leaking out.

[0039] The nozzle assembly 3 includes a first mounting plate 301 connected to the internal thread of the connection interface 105, a second mounting plate 307 is hinged at one end of the first mounting plate 301, and a nozzle 310 is fixed at one end of the second mounting plate 307. The first mounting plate 301 and the second mounting plate 307 are hinged at opposite surfaces, so that after the first mounting plate 301 is fixed, the second mounting plate 307 can rotate on the first mounting plate 301. At the same time, a nozzle 310 is installed at the center position of one end of the second mounting plate 307, and the nozzle realizes the purpose of concentrating the input gas and spraying it outward on the LCO terminal to clean the terminal.

[0040] The working principle of the PLasma gun head for cleaning ITO terminals for LCD display processing proposed in this embodiment is as follows: when in use, the mounting interface 103 at the tail end of the connector 101 is threadedly connected to the side of the interface at one end of the pipe, and the docking interface 104 provided in the mounting interface 103 is sleeved on the inner side of one end of the pipe to achieve double-layer sealing. At the same time, the tension spring 203 is expanded to push the sealing ring 201 forward, so that the front side of the sealing ring 201 is tightly attached to the gap of the pipe interface for sealing, and then the tail end of the first mounting plate 301 is threadedly connected to In the connection interface 105, during the pressurized cleaning process, the equipment inputs gas into the pipeline. The gas is input into the connector 101 through the pipeline, and the excess static pressure generated is dispersed and discharged from the first gas supply hole 302 and the second gas supply hole 308. After the discharge is completed, the second gas supply hole 308 is staggered with the first gas supply hole 302 by rotating the second mounting plate 307 until the spring rod 305 is expanded to push the positioning button 306, so that the front end of the positioning button 306 is engaged in the positioning hole 309 for fixation. The gas is then sprayed from the nozzle 310 onto the LCD terminal to clean the terminal.

[0041] Furthermore, a gas delivery slot 106 communicating with the docking interface 104 is provided in the connection interface 105;

[0042] More specifically, when the docking interface 104 is sleeved on the inner side of the pipeline, the gas input from the rear end of the pipeline is input to the gas delivery groove 106 from the front end.

[0043] Furthermore, the first mounting plate 301 and the second mounting plate 307 are both provided with a gas delivery hole 303 that communicates with the nozzle 310 , and the gas delivery hole 303 communicates with the gas delivery groove 106 ;

[0044] More specifically, after the pipeline inputs gas into the gas delivery slot 106 , the gas enters the nozzle 310 from the gas delivery hole 303 , and according to the closed-end design of the nozzle 310 , the gas is concentrated and then ejected outward.

[0045] Furthermore, a positioning button 202 is fixed to the side of the sealing ring 201, and a tension spring 203 is sleeved on the side of the positioning button 202. One end of the positioning button 202 is attached to the side of the sealing ring 201, and the other end is attached to the installation interface 103.

[0046] More specifically, the tension spring 203 has the function of expanding and pushing the sealing ring 201 outward, so that the sealing ring 201 can fit into the interface of the connected pipe and seal the gap at the interface. Under the force of the tension spring 203 pushing the sealing ring 201, the installed positioning button 202 moves back and forth in the connector 101, thereby increasing the stability of the movement of the sealing ring 201.

[0047] Furthermore, the first mounting plate 301 is provided with a mounting hole 304, a spring rod 305 is fixed in the mounting hole 304, and a positioning button 306 is sleeved in the mounting hole 304, and the second mounting plate 307 is provided with a positioning hole 309, and the positioning button 306 is engaged in the positioning hole 309;

[0048] More specifically, the diameter of the side of the positioning button 306 matches the diameter inside the mounting hole 304, which increases the stability of the extension and retraction of the positioning button 306. At the same time, the spring rod 305 has the function of expanding and pushing the positioning button 306, so that the front end of the positioning button 306 is engaged in the positioning hole 309, fixing the first mounting plate 301 and the second mounting plate 307 to prevent rotation.

[0049] Furthermore, a first gas delivery hole 302 is formed on the first mounting plate 301, and a second gas delivery hole 308 is formed on the second mounting plate 307. The first gas delivery hole 302 and the second gas delivery hole 308 are interconnected.

[0050] More specifically, the positions of the first air hole 302 and the second air hole 308 correspond to each other. By rotating the second mounting plate 307, the first air hole 302 and the second air hole 308 are aligned, thereby achieving the effect of quickly discharging static electricity. When the air holes are staggered and closed, the air is blocked to prevent external debris from entering the interior, causing dust accumulation over a long period of time, and leading to heating and aging of internal components. Compared with the traditional nozzle 310, the static electricity pressure generated cannot be quickly eliminated within six seconds. However, by opening the air holes on the mounting plate in this solution, the static electricity pressure can be controlled to be silently eliminated within six seconds.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
