Description

TECHNICAL FIELD

[0001] The application relates to the technical field of glass cutting, in particular to a glass cutting device for liquid crystal display screen production. BACKGROUND

[0002] When the existing glass substrate is cut, a cutter wheel is always located above a conveying belt and waits for line marking to improve the operation rate. However, during the waiting process, cutter wheel oil will drip on the conveying belt. When the subsequent glass is conveyed through the area on the conveying belt where the cutter wheel oil exists, the cutter wheel oil between the conveying belt and the bottom surface of the glass will affect the stability of the glass in the conveying process and the stability during subsequent line marking.

[0003] In addition, when the glass is cut by line marking, glass debris will be generated. When the glass debris contacts the cutter wheel oil on the conveying belt, the glass debris will adhere to the surface of the conveying belt under the action of the cutter wheel oil. When the subsequent glass is conveyed through the area on the conveying belt where the glass debris exists, the glass debris between the conveying belt and the bottom surface of the glass will scratch the bottom surface of the glass, which needs to be improved.

[0006] Further illustrate, the annular cleaning belt is provided with a plurality of brush hairs, the brush hairs are made of nylon material, the brush hairs made of nylon material have strong resilience and adsorption capacity.

[0007] Further illustrate, the cleaning assembly comprises an electric push rod, a support, spring telescopic rods and a squeezing roller, a plurality of electric push rods are installed in the cleaning box, the telescopic parts of all the electric push rods are fixedly connected with the support, the support is provided with a plurality of spring telescopic rods, the telescopic parts of all the spring telescopic rods are rotatably connected with the squeezing roller, and the squeezing roller is in squeezing contact with the middle part of the lower side of the annular cleaning belt.

[0008] Further illustrate, the squeezing roller is provided with a plurality of convex point structures.

[0009] Further illustrate, the cleaning assembly further comprises a water squeezing plate, the support is fixedly connected with the water squeezing plate, the water squeezing plate is in contact with the left side slope of the annular cleaning belt, and the water squeezing plate is located above the liquid level of the cleaning liquid in the cleaning box.

[0010] Further illustrate, the water squeezing plate is provided with a plurality of dense water-repellent holes.

[0011] Further illustrate, the wiping assembly comprises a water absorbing roller and a water scraping plate, the water absorbing roller is rotatably connected with the mounting bracket, the water absorbing roller comprises a hard inner rod and a sponge outer layer, the sponge outer layer of the water absorbing roller is in squeezing contact with the conveying belt on the conveying member, and the mounting bracket is fixedly connected with the water scraping plate, and the water scraping plate is in squeezing contact with the sponge outer layer of the water absorbing roller.

[0012] Further illustrate, the cleaning box is provided with a comb plate for combing the brush hairs, and the comb plate is in contact with the right side slope of the annular cleaning belt.

[0013] Further illustrate, the comb plate is located below the liquid level of the cleaning liquid in the cleaning box.

[0014] Further illustrate, all the bearing seats are provided with a support block, and the support block is embedded in the annular bearing belt.

[0015] The beneficial effects of the present application are: 1. When the area with oil stains and glass fragments on the surface of the conveying belt moves left through the annular cleaning belt, the annular cleaning belt can take most of the oil stains and glass fragments on the surface of the conveying belt to the right, so that the oil stains on the surface of the conveying belt can be cleaned, and most of the sharp glass fragments can be prevented from entering the area between the conveying belt and the annular cleaning belt, thereby preventing the conveying belt and the annular cleaning belt from being damaged.

[0016] 2. As the brush bristles move along the circular cleaning belt and come into contact with and pass through the conveyor belt, they are pressed to the left by the conveyor belt. As they gradually detach from the conveyor belt, the bristles also gradually spring back to the right. Because the bristles have a certain length, they can come into contact with the surface of the conveyor belt after they spring back. Therefore, during their rightward springback, the bristles will push the glass shards on the surface of the conveyor belt that have not yet come into contact with the circular cleaning belt to the lower right, thus improving the cleaning effect on the glass shards.

[0017] 3. This invention uses a squeezing roller to reciprocate the squeezing of the annular cleaning belt; under the reciprocating squeezing of the squeezing roller, the sponge-material annular cleaning belt repeatedly absorbs and discharges the cleaning liquid in the cleaning tank, causing oil stains and glass fragments to detach from the annular cleaning belt and brush bristles along with the cleaning liquid, thereby performing squeezing cleaning on the annular cleaning belt.

[0018] 4. When the bristles on the annular cleaning belt pass through the comb plate, the comb plate combs off the glass fragments on the bristles. At the same time, the comb plate scrapes off the glass fragments on the annular cleaning belt, preventing a large amount of glass fragments from being squeezed by the extrusion rollers along with the annular cleaning belt. This would cause the glass fragments to be squeezed into the pores of the annular cleaning belt, resulting in them being exposed on the annular cleaning belt when it comes into contact with the conveyor belt later, thus damaging the conveyor belt.

Detailed Implementation

[0021] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0022] Example 1 A glass cutting device for LCD screen production, such as Figures 1-8 As shown, it includes a mounting frame 1, a glass precision cutter 2, and a conveyor 3; the mounting frame 1 is equipped with the glass precision cutter 2 for cutting glass; the mounting frame 1 is equipped with the conveyor 3 for conveying glass, and the conveyor 3 is an electric belt conveyor. It also includes bearing housings 4, electric drive shafts 5, annular bearing belts 6, annular cleaning belts 7, arc-shaped limiting blocks 8, cleaning boxes 10, guide rollers 11, cleaning components, and wiping components; the mounting frame 1 is equipped with four rectangularly distributed bearing housings 4; each pair of bearing housings 4 symmetrically arranged front and rear are rotatably connected to an electric drive shaft 5; the mounting frame 1 is equipped with a cleaning box 10, which contains cleaning fluid; guide rollers 11 are rotatably connected to the cleaning box 10, and the electric drive shafts 5 and guide rollers 11 form an isosceles triangle with the apex angle pointing downwards; all electric drive shafts 5 and guide rollers 11 are connected to an annular bearing belt 6; annular cleaning belts 7 are provided on the annular bearing belt 6. The lower center of the carrier belt 6 and the annular cleaning belt 7 are submerged in the cleaning liquid inside the cleaning box 10, and the annular cleaning belt 7 is made of sponge material; the conveyor belt on the conveyor 3 is an isosceles triangle structure with the apex angle pointing downwards; the upper center of the annular cleaning belt 7 is in extrusion contact with the conveyor belt on the conveyor 3; two symmetrically distributed arc-shaped limiting blocks 8 are provided on the mounting frame 1, and the arc-shaped limiting blocks 8 are in contact with the annular carrier belt 6. Under the limiting action of the arc-shaped limiting blocks 8, the upper center of the annular carrier belt 6 and the annular cleaning belt 7 are concave downwards in an arc shape; the cleaning box 10 is provided with a cleaning component for cleaning oil stains on the annular cleaning belt 7; the mounting frame 1 is provided with a wiping component for wiping the conveyor belt.

[0023] The annular cleaning belt 7 is equipped with several matrix-distributed bristles 9. The bristles 9 are made of nylon, which has strong resilience and adsorption capacity.

[0024] The specific operation of this embodiment is as follows: Firstly, the operator or the control robot places the glass on the conveying belt of the conveying member 3; then, the control member 3 is started to drive the conveying belt to rotate clockwise in the forward-to-backward view, to convey the glass to the right below the glass cutting machine 2, and then the glass cutting machine 2 is started to score and cut the glass; then, the control member 3 is started to drive the conveying belt to convey the cut glass to the right, and the operator or the control robot transfers the cut glass, to realize the glass cutting operation.

[0025] With the continuous rotation of the conveying belt, the control member 3 drives the annular conveying belt 6 and the annular cleaning belt 7 to rotate counterclockwise in the forward-to-backward view. When the area of the conveying belt surface attached with oil stains and glass fragments moves to contact the annular cleaning belt 7, since the annular cleaning belt 7 is in extrusion contact with the conveying belt, and the rotation directions of the conveying belt and the annular conveying belt 6 are different, when the area of the conveying belt surface attached with oil stains and glass fragments moves to the left through the annular cleaning belt 7, the annular cleaning belt 7 can take most of the oil stains and glass fragments on the conveying belt surface to the right, so that the oil stains on the conveying belt surface can be cleaned, and most of the sharp glass fragments can be prevented from entering the area between the extrusion of the conveying belt and the annular cleaning belt 7, to avoid the problem of the rapid and serious damage of the conveying belt and the annular cleaning belt 7.

[0026] Meanwhile, the cleaning assembly and the cleaning liquid in the cleaning box 10 can clean the oil stains and glass fragments on the annular cleaning belt 7 in time, so that the annular cleaning belt 7 can continuously clean the conveying belt; and the wiping assembly can wipe the residual oil stains and cleaning liquid on the conveying belt surface, to ensure the stability of the conveying belt when conveying the glass. To ensure the cleaning effect of the cleaning liquid in the cleaning box 10, the cleaning liquid in the cleaning box 10 can be replaced regularly.

[0027] Further, although the above process can avoid the problem of the rapid and serious damage of the conveying belt and the annular cleaning belt 7, the problem of the damage of the conveying belt and the annular cleaning belt 7 by the glass fragments still exists. Therefore, the brush 9 on the annular cleaning belt 7 can clean the glass fragments on the conveying belt, to ensure the service life of the conveying belt and the annular cleaning belt 7.

[0028] Further, considering that most conveying belts can enhance the friction force through the design of anti-skid grooves or anti-skid lines, to ensure the stability of the glass in the conveying process, the glass fragments entering the anti-skid grooves or anti-skid lines are difficult to be taken out to the right by the annular cleaning belt 7, therefore, the brush 9 can also clean the conveying belt with the anti-skid grooves or anti-skid lines.

[0029] Furthermore, as the brush bristles 9 come into contact with and pass through the conveyor belt along with the circular cleaning belt 7, they are pressed to the left by the conveyor belt. As they gradually detach from the conveyor belt, the brush bristles 9 also gradually spring back to the right. Since the brush bristles 9 have a certain length, they can come into contact with the surface of the conveyor belt after they spring back. Therefore, during their rightward springback, the brush bristles 9 will push the glass shards on the surface of the conveyor belt that have not yet come into contact with the circular cleaning belt 7 to the lower right, thus improving the cleaning effect on the glass shards.

[0030] It should be noted that because the bristles 9 have an adsorption capacity, when the bristles 9 are pressed and bent to the left by the conveyor belt, although they will cover part of the annular cleaning belt 7, causing part of the annular cleaning belt 7 to come into contact with the conveyor belt through the bristles 9, the bristles 9 with adsorption capacity can still clean the residual oil on the conveyor belt after absorbing the cleaning liquid, without affecting the cleaning effect of the annular cleaning belt 7 on the conveyor belt.

[0031] Furthermore, under the limiting action of the arc-shaped limiting block 8, the upper middle part of the annular carrying belt 6 and the annular cleaning belt 7 is concave downwards in an arc shape, fitting against the outer side of the downward-facing corner of the conveyor belt, so that the upper side of the annular cleaning belt 7 presents an arc-shaped structure with the middle concave downwards, such as... Figure 4 As shown, the curvature of the arc structure is smaller than the curvature of the outer side of the top corner of the conveyor belt, and the left and right ends of the arc structure are much higher than the top corner of the conveyor belt. When glass fragments on the surface of the conveyor belt that have not yet come into contact with the annular cleaning belt 7 are pushed to the right by the brush bristles 9, they will be intercepted by the upper arc-shaped annular cleaning belt 7 and the brush bristles 9, thus preventing them from flying outward and increasing the difficulty of subsequent glass fragment cleaning and collection.

[0032] Example 2 Based on the above embodiment 1, as follows Figures 3-8 As shown, the cleaning assembly includes an electric push rod 12, a bracket 13, a spring telescopic rod 14, and a squeeze roller 15; at least four rectangularly distributed electric push rods 12 are installed inside the cleaning box 10; the telescopic parts of all electric push rods 12 are fixedly connected to the bracket 13; the bracket 13 is equipped with at least two symmetrically distributed spring telescopic rods 14; the telescopic parts of all spring telescopic rods 14 are rotatably connected to the squeeze roller 15, and the squeeze roller 15 makes a squeezing contact with the lower center of the annular cleaning belt 7.

[0033] The extrusion roller 15 has several protrusion structures distributed on it.

[0034] The cleaning assembly also includes a wringer 16; the wringer 16 is fixed to the bracket 13 and contacts the left inclined surface of the annular cleaning belt 7, and the wringer 16 is located above the liquid surface of the cleaning liquid in the cleaning tank 10.

[0035] The dewatering plate 16 has several densely packed drainage holes. When the annular cleaning belt 7, which absorbs a large amount of cleaning liquid, is squeezed, the cleaning liquid absorbed on the annular cleaning belt 7 is discharged more quickly through the densely packed drainage holes on the dewatering plate 16, thereby improving the dewatering efficiency.

[0036] The wiping assembly includes a water-absorbing roller 40 and a squeegee 41; the water-absorbing roller 40 is rotatably connected to the mounting frame 1; the water-absorbing roller 40 consists of a rigid inner rod and a sponge outer layer; the sponge outer layer of the water-absorbing roller 40 is in compression contact with the conveyor belt on the conveyor 3; the squeegee 41 is fixedly connected to the mounting frame 1, and the squeegee 41 is in compression contact with the sponge outer layer of the water-absorbing roller 40.

[0037] The specific steps for cleaning the components are as follows: When the annular cleaning belt 7 passes the squeezing roller 15, the telescopic part of the control electric push rod 12 drives the bracket 13, spring telescopic rod 14, squeezing roller 15 and water squeezing plate 16 to move up and down reciprocally. The squeezing roller 15 squeezes the annular cleaning belt 7 reciprocally. Under the reciprocating squeezing of the squeezing roller 15, the sponge material annular cleaning belt 7 repeatedly absorbs and discharges the cleaning liquid in the cleaning box 10, so that oil stains and glass fragments are separated from the annular cleaning belt 7 and brush bristles 9 along with the cleaning liquid, thereby performing squeezing cleaning on the annular cleaning belt 7. When the squeezing roller 15 is in contact with the annular cleaning belt 7 and the annular cleaning belt 7 is running, the squeezing roller 15 rotates under the action of friction.

[0038] At the same time, the reciprocating squeezing plate 16 squeezes the annular cleaning belt 7, which is full of cleaning liquid, to squeeze out most of the cleaning liquid quickly, leaving only a small amount of cleaning liquid on the annular cleaning belt 7. This ensures that the annular cleaning belt 7 can dissolve oil stains while also ensuring that the annular cleaning belt 7 can adsorb the dissolved oil stains, and avoids the annular cleaning belt 7 from coming into contact with the conveyor belt in an overly wet state, which would make it difficult for the annular cleaning belt 7 to effectively adsorb and treat the oil stains.

[0039] It should be noted that as the pressure of the extrusion roller 15 on the annular cleaning belt 7 increases, the movement of the annular cleaning belt 7 becomes increasingly difficult. At this point, the sudden increase in local resistance leads to an imbalance of friction, causing the electric drive shaft 5 to spin freely, which in turn causes the annular carrier belt 6 to stop, resulting in slippage at the transmission connection between the electric drive shaft 5 and the annular carrier belt 6. Therefore, the spring telescopic rod 14 provides space for the extrusion roller 15 to move, allowing the extrusion roller 15 to elastically extend and retract as the annular cleaning belt 7 moves, ensuring that the annular cleaning belt 7 can operate and move normally while being squeezed by the extrusion roller 15.

[0040] It should be noted that when the extrusion roller 15 performs a reciprocating rotational extrusion operation on the annular cleaning belt 7, the protrusion structure on the extrusion roller 15 can form a point-like high-pressure area on the annular cleaning belt 7, so that the pressure is more concentrated on the oil stains on the surface of the annular cleaning belt 7. When the annular cleaning belt 7 is squeezed in the cleaning liquid in the cleaning box 10, the protrusion structure can squeeze out the deep oil stains.

[0041] The wiping component works as follows: When the conveyor belt passes the suction roller 40, the sponge outer layer on the suction roller 40 wipes away the dissolved oil and cleaning fluid remaining on the surface of the conveyor belt, so as to ensure the stability of the conveyor belt when transporting glass. At the same time, the operation of the conveyor belt will cause the suction roller 40 to rotate together. When the suction roller 40 rotates, its sponge outer layer will be squeezed by the scraper 41, squeezing out the liquid it has absorbed, so that the suction roller 40 can continuously perform wiping work.

[0042] Example 3 Based on the above embodiment 2, such as Figures 3-8 As shown, the cleaning box 10 is equipped with a comb plate 21 for combing the bristles 9, and the comb plate 21 is in contact with the right inclined surface of the annular cleaning belt 7.

[0043] The comb plate 21 is located below the surface of the cleaning liquid in the cleaning tank 10. It cleans the glass shards on the bristles 9 in the cleaning liquid, preventing the glass shards from splashing everywhere and being difficult to collect.

[0044] All bearing housings 4 are provided with a common support block 30, and the support block 30 is fitted inside the annular bearing belt 6.

[0045] The specific operation of this embodiment is as follows: When the bristles 9 on the annular cleaning belt 7 pass through the comb plate 21, the comb plate 21 combs off the glass fragments on the bristles 9. At the same time, the comb plate 21 scrapes off the glass fragments on the annular cleaning belt 7, preventing a large amount of glass fragments from being squeezed by the squeeze roller 15 along with the annular cleaning belt 7. This would cause the glass fragments to be squeezed into the pores of the annular cleaning belt 7, resulting in them being exposed on the annular cleaning belt 7 when it comes into contact with the conveyor belt later, thus damaging the conveyor belt. When the cleaning fluid in the cleaning box 10 is replaced, the glass fragments deposited at the bottom of the cleaning fluid are also cleaned.

[0046] When the squeezing roller 15 and the dewatering plate 16 squeeze the annular cleaning belt 7, the support block 30 provides support for the annular carrying belt 6 and the annular cleaning belt 7, acting as a pad to prevent the annular carrying belt 6 and the annular cleaning belt 7 from being concave inward due to the squeezing of the squeezing roller 15 and the dewatering plate 16.

Therefore, the scope of this disclosure should not be limited to the above embodiments, but should be defined not only by the appended claims, but also by their equivalents.
