Description

Technical Field

[0001] The invention relates to glass substrate processing equipment, in particular to ultrasonic cleaning equipment for LCD glass substrates. Background Art

[0002] LCD (liquid crystal display) glass substrate is one of the key components of liquid crystal display, mainly used to carry liquid crystal materials and form display images. LCD glass substrate is usually composed of two ultra-thin glass plates. The processing of LCD glass substrate requires first cutting the large piece of glass into the required size, then removing impurities and contaminants on the surface of the glass, and then coating the glass surface with a transparent conductive layer (ITO), forming an electrode pattern through a photolithography process, and then coating the ITO layer with an orientation layer. The liquid crystal molecules are oriented through friction or photo-orientation technology, and finally the two glass substrates are aligned and bonded, the liquid crystal material is injected in the middle, and the edges are sealed.

[0003] When removing impurities and contaminants from the glass surface, the traditional cleaning method is to manually rinse with a high-pressure water gun. However, not only is it easy to have incomplete cleaning, but also fingerprints and other impurities that are not conducive to coating will be left on the glass again by manual handling after cleaning. Therefore, the prior art places the glass substrate in an ultrasonic cleaning device and cleans it through the ultrasonic device to shake off all the impurities on the surface of the glass substrate. However, the ultrasonic cleaning device is extremely effective when used for cleaning a single glass substrate. If multiple glass substrates are ultrasonically cleaned at the same time, the glass plate near the middle position is blocked by other glass plates and the ultrasonic effect is weaker, so that the glass in the middle cannot be cleaned, affecting the cleaning quality of the entire batch.

[0004] Therefore, this case aims to provide an ultrasonic cleaning device for LCD glass substrates, which adopts a highly adaptable fence, which can not only enable the fence to be stably installed in the equipment, but also be removed for cleaning at any time, and at the same time, the glass substrates fixed in the fence can all be subjected to a uniform ultrasonic cleaning effect, thereby ensuring the efficiency of the same batch cleaning. Summary of the invention

[0005] The present invention provides an ultrasonic cleaning device for LCD glass substrate, which can effectively solve the above problems.

[0006] The present invention is achieved in that:

[0007] An ultrasonic cleaning device for LCD glass substrates comprises a water tank filled with cleaning water, wherein the upper end of the water tank is connected to a water inlet pipe and a mixing liquid pipe, the lower end of the water tank is connected to a water outlet pipe, an ultrasonic generator and an ultrasonic transducer are arranged inside the water tank, and the ultrasonic cleaning device also comprises: a glass fixing fence, comprising a containing frame arranged inside the water tank and used to place the glass substrate, the containing frame is provided with a plurality of fence seats for limiting the position of the glass, an outer frame is fixed to the outer side of the containing frame, the outer frame is spaced apart from the inner wall of the water tank, and positioning grooves are arranged on four prisms of the outer frame; a self-fixing limiting structure, the Two groups of pressure blocks are arranged at the bottom of the outer frame, and the outer frame is spaced apart from the containing frame. The self-fixing limiting structure includes a lower matching groove opened at the bottom of the water tank and matched with the pressure block. Two symmetrical cavities are opened in the gap between the outer frame and the containing frame, and the head end of the cavity is communicated with the lower matching groove. A movable stamping seat is slidably installed at the end of the lower matching groove, and the cavity is connected to an external airway; an inner gap fluctuation structure, a guide hole is opened on the outer side of the fence seat, and the inner gap fluctuation structure includes a vibration baffle arranged between the two fence seats, the bottom opening of the vibration baffle is opposite to the guide hole, and a blower is arranged on the inner side of the vibration baffle.

[0008] As a further improvement, a plurality of straight rails are provided in the accommodating frame, and the fence seat comprises a plurality of connecting rails slidably mounted on the straight rails, and guide holes are provided on the connecting rails.

[0009] As a further improvement, the connecting rail includes a clamping seat that slidably cooperates with the straight rail, and a connecting button is welded on both sides of the clamping seat. When the clamping seats are close to each other, adjacent connecting buttons are connected to each other.

[0010] As a further improvement, the clamping seat is divided into a left clamping plate and a right clamping plate of the same shape and structure. The left clamping plate includes a slide plate that cooperates with the straight rail. The slide plate is fixed with a clamping plate that rotates through a torsion spring. The inner side of the clamping plate is attached to the glass substrate.

[0011] As a further improvement, the lower matching groove is a square groove, and the pressure block is a square block. When the pressure block cooperates with the lower matching groove, the head end of the cavity is blocked.

[0012] As a further improvement, the cavity includes a transverse portion located at the lower end of the gap between the outer frame and the accommodating frame, a T-shaped portion located laterally of the gap between the outer frame and the accommodating frame and communicating with the transverse portion, and the movable stamping seat is slidably mounted on the openings at both ends of the T-shaped portion.

[0013] As a further improvement, the movable stamping seat includes a spring arranged on the inner side of the openings at both ends of the T-shaped portion, and the spring is connected to a stamping block. After gas is introduced into the external airway, the stamping block is pushed out and clamped in the positioning groove of the outer frame.

[0014] As a further improvement, the vibration baffle comprises a vibration plate arranged between two fence seats, the interior of the vibration plate is hollow, and a winding bucket is arranged at the bottom of the vibration plate, and the winding bucket faces the guide hole.

[0015] As a further improvement, the blower includes an upper curved pipe arranged on the vibration plate, and a blowing member is arranged at the bottom of the inner side of the upper curved pipe.

[0016] The beneficial effects of the present invention are:

[0017] In the existing cleaning process of glass substrates, single-piece cleaning is mostly adopted, and the whole piece of glass is directly placed in the cleaning device to achieve ultrasonic cleaning of the glass substrate. Once batch cleaning is required, not only is it difficult to solve the problem of fixing the batch of glass, but it is also difficult for ultrasonic water to diffuse into the gaps between the glass and the glass, thereby affecting the effect of batch cleaning. Therefore, the present invention, through the additional glass fixing fence, firstly provides a accommodating frame and a fence seat for placing glasses in batches, so that the glasses can be embedded in the fence seat piece by piece, so that the glasses form a stable gap arrangement, so that ultrasonic water and impurities after being cleaned can have enough gaps to flow, thereby achieving the effect of improving the cleaning efficiency.

[0018] Because different processing requirements may result in different glass sizes, if fixed hurdles are used, the fixed points are relatively rigid, whether for large or small glass, and it is difficult to achieve the effect of multi-point uniform compensation. Therefore, the hurdles are configured to slide in the accommodating frame, so that the position of the hurdles can be adjusted according to the size of the glass and the installation position. In addition, when the glass substrate is small, a single group of hurdles can be combined into a group of hurdles through a connecting button, thereby improving the practical effect of the present invention.

[0019] In the process of clamping the glass substrate, since the fence seat is set to slide, the clamping state needs to be maintained during the fixing process of the substrate. Therefore, the clamping seat is set to clamp left and right, and the glass substrate is stabilized at multiple points through two automatically rebounding clamping plates, and can be easily disassembled after cleaning.

[0020] In order to improve the cleaning efficiency, it is necessary to increase the output power of the ultrasonic generator. In order to ensure the stability of the glass after the power is increased, the present invention provides a self-fixing limiting structure on the basis of the glass fixing railing. When the glass fixing railing is cleaned, it can be placed in the water tank. Through the cooperation of the pressure block and the lower matching groove, and the premise that the movable stamping seat seals the other side of the cavity, the two ends of the cavity are sealed by the movable stamping seat and the pressure block, and then the cavity is pressurized through the external air duct, so that the movable stamping seat is pushed out to achieve the cooperation with the positioning groove on the external frame, thereby achieving the effect of bottom limiting and lateral limiting. No matter how large the power of the ultrasonic generator is, the railing in the water can be kept in a stable state, and the glass is fixed by the railing seat limit, so as to achieve a stable effect.

[0021] When the glass fixing railing is placed in, the head end of the cavity needs to be completely sealed, so the lower matching groove in the present invention is matched with the pressure block, so that the lower matching groove can be completely blocked after the pressure block is placed, thereby providing a basis for the push-out of the movable stamping seat.

[0022] The movable stamping seat can seal the cavity in a normal relaxed state, so that when the cavity is pressurized, the stamping block in the movable stamping seat will rush out and limit the outer frame in the up and down directions. After the external force disappears, the spring can drive the stamping block to reset, so that the stamping block no longer hinders the positioning groove, allowing the glass fixing railing to be directly taken out.

[0023] The self-fixing limiting structure realizes the stable installation of the whole railing, so that the glass can be fixed with a stable gap, but the gap between the glasses can still be treated with a good effect. Therefore, the present invention adds an internal gap wave structure, and sets a vibrating baffle between every two railing seats to contain water in the water tank. The water in the vibrating baffle is blown toward the glass substrates on both sides by a blower, so that the inner glass substrate can also achieve a flushing cleaning effect, and then with the sideways influx of ultrasonic water, a comprehensive cleaning effect is achieved. Even in the process of batch cleaning, the effect of single-piece cleaning can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Reference Figures 1 to 9 As shown, an ultrasonic cleaning device for LCD glass substrates comprises a water tank 11 filled with cleaning water, the upper end of the water tank 11 is connected to a water inlet pipe and a mixing pipe, the lower end of the water tank 11 is connected to a water outlet pipe, the upper end of the water tank 11 is provided with an upper cover, the inner side of the water tank 11 is provided with a plurality of ultrasonic generators, the ultrasonic cleaning device also comprises: a glass fixing fence, comprising a containing frame 21 arranged inside the water tank 11 and used to place the glass substrate, the containing frame 21 is provided with a plurality of fence seats 22 for limiting the position of the glass, an outer frame 23 is also fixed to the outer side of the containing frame 21, the outer frame 23 is spaced apart from the inner wall of the water tank 11, and positioning grooves 24 are provided on four prisms of the outer frame 23; a self-fixing limiting structure 30, the outer frame 23 Two groups of pressure blocks 25 are arranged at the bottom, the outer frame 23 and the containing frame 21 are arranged at intervals, the self-fixing limiting structure 30 includes a lower matching groove 31 opened at the bottom of the water tank 11 and matched with the pressure block 25, and two symmetrical cavities 32 are opened in the interval between the outer frame 23 and the containing frame 21, the head end of the cavity 32 is communicated with the lower matching groove 31, and the end of the lower matching groove 31 is slidably installed with a movable stamping seat 33, and the cavity 32 is connected to an external airway; an inner gap fluctuation structure 40, a guide hole 221 is opened on the outer side of the fence seat 22, and the inner gap fluctuation structure 40 includes a vibration baffle 41 arranged between the two fence seats 22, the bottom opening of the vibration baffle 41 is opposite to the guide hole 221, and a blower 42 is arranged on the inner side of the vibration baffle 41.

[0039] In the overall cleaning process, the glass fixing railing is first placed in the water tank 11, and then water is introduced through the water inlet pipe after the glass fixing railing is fixed. Different solutions are selected to be introduced through the mixing pipe according to the material of the glass substrate, and then the upper cover is closed, and the ultrasonic generator and ultrasonic transducer are turned on.

[0040] In the existing cleaning process of glass substrates, single-piece cleaning is mostly adopted, and the whole piece of glass is directly placed in the cleaning device to achieve ultrasonic cleaning of the glass substrate. Once batch cleaning is required, not only is it difficult to solve the problem of fixing the batch of glass, but it is also difficult for ultrasonic water to diffuse into the gaps between the glass and the glass, thereby affecting the effect of batch cleaning. Therefore, the present invention, through the additional glass fixing fence, firstly provides a accommodating frame 21 and a fence seat 22 for placing glass in batches, so that the glass can be embedded in the fence seat 22 piece by piece, so that the glass forms a stable gap arrangement, so that ultrasonic water and impurities after cleaning can have enough gaps to flow, thereby achieving the effect of improving the cleaning efficiency.

[0041] Since different processing requirements may lead to different glass sizes, if a fixed hurdle seat 22 is used, whether it is fixing a large glass or a small glass, the fixed point is relatively rigid, and it is difficult to achieve the effect of multi-point uniform compensation. Therefore, the accommodating frame 21 of this embodiment is provided with a plurality of straight rails 223, and the hurdle seat 22 includes a plurality of connecting hurdles 222 slidably mounted on the straight rails 223. The connecting hurdles 222 are provided with guide holes 221, and the hurdle seat 22 is arranged to be able to slide in the accommodating frame 21, so that the hurdle seat 22 can be adjusted according to the size of the glass and the installation position. The connecting bar 222 comprises a clamping seat 2221 which is slidably matched with the straight rail 223. A connecting button 2222 is welded on both sides of the clamping seat 2221. When the clamping seats 2221 are close to each other, the adjacent connecting buttons 2222 are connected to each other. In the case where the glass substrate is small, the connecting button 2222 can be used to merge a single group of bar seats 22 into a group of bar seats 22, thereby improving the practical effect of the present invention. In this embodiment, the connecting button 2222 is configured as a magnet, and in other embodiments, it can also be configured as a hook plate or a connecting buckle.

[0042] In the process of clamping the glass substrate, since the fence seat 22 is set to slide, it is necessary to maintain a clamped state during the fixing process of the substrate. Therefore, the clamping seat 2221 of this embodiment is divided into a left clamping piece and a right clamping piece with the same shape and structure. The left clamping piece includes a slide plate 201 matched with the straight rail 223. A clamping plate 202 rotated by a torsion spring is fixed to the slide plate 201. The inner side of the clamping plate 202 is attached to the glass substrate. The clamping seat 2221 is set to a left and right clamping mode. The glass substrate is stabilized at multiple points by two clamping plates 202 that can automatically rebound, and can be easily disassembled after cleaning.

[0043] In order to improve the cleaning efficiency, it is necessary to increase the output power of the ultrasonic generator. In order to ensure the stability of the glass after the power is increased, the present invention provides a self-fixing limiting structure 30 on the basis of the glass fixing fence. When the glass fixing fence is cleaned, it can be placed in the water tank 11. Through the cooperation of the pressure block 25 and the lower matching groove 31, and the premise that the movable stamping seat 33 seals the other side of the cavity 32, the two ends of the cavity 32 are sealed through the movable stamping seat 33 and the pressure block 25, and then the cavity 32 is pressurized through the external air channel, so that the movable stamping seat 33 is pushed out, and the cooperation with the positioning groove 24 on the outer frame 23 is realized, thereby achieving the effect of bottom limiting and lateral limiting. No matter how high the power of the ultrasonic generator is, the fence located in the water can be kept in a stable state, and the glass is fixed by the fence seat 22, so as to achieve a stable effect.

[0044] When the glass fixing railing is placed in, the head end of the cavity 32 needs to be completely sealed. Therefore, the lower matching groove 31 of this embodiment is a square groove, and the pressure block 25 is a square block. When the pressure block 25 cooperates with the lower matching groove 31, the head end of the cavity 32 is blocked. The lower matching groove 31 and the pressure block 25 are matched, so that after the pressure block 25 is placed, the lower matching groove 31 can be completely blocked, thereby providing a basis for the push-out of the movable stamping seat 33.

[0045] In this embodiment, the cavity 32 includes a transverse portion 321 located at the lower end of the gap between the outer frame 23 and the accommodating frame 21, a T-shaped portion 322 located laterally of the gap between the outer frame 23 and the accommodating frame 21 and communicating with the transverse portion 321, and the movable stamping seat 33 is slidably installed in the openings at both ends of the T-shaped portion 322, so that a closed cavity can be formed from the pressure block 25 to the movable stamping seat 33. By setting the cavity as a special-shaped structure, the effect of forming a sealed cavity is achieved.

[0046] The movable punching seat 33 can seal the cavity 32 in a normal diastolic state, so that when the cavity 32 is pressurized, the punching block 332 in the movable punching seat 33 will rush out and limit the outer frame 23 in the up and down directions. After the external force disappears, the spring 331 can drive the punching block 332 to return to its original position, so that the punching block 332 no longer forms an obstacle to the positioning groove 24, allowing the glass fixing railing to be directly taken out.

[0047] The self-fixing limiting structure 30 realizes the stable installation of the whole railing, so that the glass can be fixed with a stable gap, but the gap between the glasses can still be treated with a good effect. Therefore, the present invention adds an inner gap wave structure 40, and sets a vibration partition 41 between every two railing seats 22 to contain water in the water tank 11. The water in the vibration partition 41 is blown toward the glass substrates on both sides by the blower 42, so that the inner glass substrate can also achieve a flushing cleaning effect, and then with the sideways influx of ultrasonic water, a comprehensive cleaning effect is achieved. Even in the process of batch cleaning, the effect of single-piece cleaning can be achieved.

[0048] The entire vibration baffle 41 is arranged between the two fence seats 22. In order to achieve the effect from the bottom to the top of the substrate, the vibration baffle 41 includes a vibration plate 411 arranged between the two fence seats 22. The interior of the vibration plate 411 is hollow, and a winding bucket 412 is arranged at the bottom of the vibration plate 411. The winding bucket 412 faces the guide hole 221, so that the mixed water flow can be flushed out through the winding bucket 412. However, the mixed water flow is not only poured into the guide hole 221, but also poured into the area where the connecting fence 222 is not set. In this embodiment, the left clamping plate and the right clamping plate are not provided with serrated openings. In other embodiments, the left clamping plate and the right clamping plate can be set as serrated openings so that the mixed water flow entering the guide hole 221 can be flushed and cleaned along the outer surface of the substrate through the opening position.

[0049] The power source in the vibrating partition 41 comes from the blower 42. In order to provide power while preventing water from flowing into the blower 42, the blower 42 includes an upper curved pipe 421 arranged on the vibrating plate 411. A blowing member 422 is arranged at the bottom of the inner side of the upper curved pipe 421, and the blowing member 422 can directly provide downward impact force. If the impact force is not enough, the external pipeline can be connected to the blowing member 422 to realize two-stage energy supply, and the design of the upper curved pipe 421 can prevent the water in the water tank 11 from flowing back into the blowing member 422.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
