Description

Technical Field

[0001] The invention belongs to the technical field of glass processing, and relates to a thermal cutting dust suction device, in particular to a thermal cutting dust suction device for producing liquid crystal display screen glass. Background Art

[0002] The thermal cutting dust collection device is an important process equipment for collecting dust during the cutting of TFT-LCD liquid crystal glass, LTPS display glass and industrial glass. Various glasses will produce a certain amount of glass chips and dust during the scribing and cutting process. Various glasses have different requirements for dust. It is necessary to ensure that the dust pollution on the glass surface is minimized during the scribing and breaking process, and improve the surface quality requirements of the glass. In particular, glass chips will splash, raise dust, and fall during the glass breaking process, which will cause adhesion to the glass surface, causing surface damage and scratches on the product, or adhere to the glass surface at high temperature and cannot be cleaned, causing surface bulges, resulting in unqualified appearance quality, unqualified products and affected production, resulting in waste of resources, and significantly reduced yield rate of LCD panel production lines, increased costs, poor market competitiveness, and will affect the sales price and corporate brand image of the product, and have the serious consequence of being unable to sell.

[0003] After searching, for example, a Chinese patent document discloses a TFT-LCD liquid crystal glass thermal cutting dust suction device [Application No.: 202120556253.2; Publication No.: CN215049680U]. This dust suction device includes a high-temperature resistant metal bellows, the front of which is provided with a plurality of dust suction holes in a matrix, and a plurality of the dust suction holes are provided with a plurality of detachable high-temperature resistant plugging nails; a plurality of high-temperature resistant metal connecting pipes are evenly distributed along the length direction in the middle of the back of the high-temperature resistant metal bellows, a high-temperature resistant air pressure regulating valve is provided on the high-temperature resistant metal connecting pipe, and the high-temperature resistant metal connecting pipe is connected to the dust collector through a high-temperature resistant silicone steel wire hose. The suction air pressure can be adjusted through the air pressure regulating valve. The threaded holes can be installed or removed to increase or decrease the suction force locally. The adjustment can be made according to the location where glass dust is generated. The suction force can be increased in locations with a lot of dust and dust suction holes can be added. The suction force in locations with less dust can be reduced. Screws can be used to plug holes in dust-free areas to increase the suction force in other locations in disguise.

[0004] Although the dust suction mechanism disclosed in the patent can adjust the dust suction air pressure through the air pressure regulating valve, the threaded hole can be installed or removed to locally increase or reduce the dust suction force, and can be adjusted according to the location where the glass dust is generated. However, the dust suction mechanism inputs an open dust suction operation, and during the cutting process, the debris and dust generated by the cutting knife or external factors will splash outward. It is difficult for the existing open dust suction mechanism to completely absorb the dust, which not only affects the external environment, but also affects the processing of the glass. Summary of the invention

[0008] During operation, after the device is moved to the specified position by the moving wheels, the device is connected to the thermal cutting machine through the connecting component, and the height of the dust hood and the semicircular telescopic hood can be adjusted by the lifting cylinder so that the glass is located between the dust hood and the semicircular telescopic hood. The two semicircular tubes are driven by the driving component to move relative to each other so that the two semicircular tubes wrap the mounting column on which the cutting head on the thermal cutting machine is mounted, thereby making the two semicircular hoods and the two semicircular telescopic hoods wrap the cutting head. During cutting, the two semicircular telescopic hoods contact the upper side of the glass, and the dust hood contact the lower side of the glass, thereby making the cutting head located in a relatively closed environment.

The clamping motor drives the bidirectional screw to rotate so that the two moving blocks move relative to each other, thereby splicing the two semicircular tubes. The inner diameter of the semicircular tube is larger than the outer diameter of the mounting column of the cutting head, thereby leaving an air inlet gap.

[0018] The connecting assembly includes an electric telescopic rod and a connecting cover. The electric telescopic rod is fixed on the right side of the base. A limiting plate is fixed to the telescopic end of the electric telescopic rod. A sliding rod is slidably connected to the limiting plate. The sliding rod is slidably connected to the base.

A mounting plate is fixed to the right end of the connecting cover. A plurality of connecting bolts are threadedly connected to the mounting plate. The mounting plate is connected to an arc-shaped connecting seat through the connecting bolts.

[0019] When the above structure is adopted, during installation, if the cutting machine has a circular tube structure, the fastening column can be extended into the fastening cover, and then the fastening cover can be inserted into the circular tube structure, so that the limit plate can be in contact with the circular tube mechanism, and the electric telescopic rod can be driven.

When bolt holes are provided on the cutting machine, the device can be connected and fixed to the cutting machine through the bolt holes by utilizing the cooperation of the mounting plate and the connecting bolts. When a rod-shaped structure is provided on the cutting machine, the rod-shaped structure on the cutting machine can be clamped and fixed by utilizing the cooperation of the arc-shaped connecting seat and the mounting plate. The arrangement of the above structure can meet different installation requirements and can be adjusted according to needs, and is highly practical.

[0020] The dust suction device includes a closing plate, a dust suction chamber with a front end opening is provided inside the base, a fan is fixed to the lower end of the dust suction chamber, slide rails are fixed to the left and right sides of the dust suction chamber, a slide plate is fixed to the rear side of the closing plate, slide grooves cooperating with the slide rails are provided on the left and right sides of the slide plate, a shielding cover is fixed to the upper periphery of the slide plate, a circular opening is provided in the middle of the slide plate, a filter cartridge is rotatably connected to the upper side of the slide plate, the upper end of the filter cartridge abuts against the upper end of the dust suction chamber, the dust suction pipe is connected to the dust suction chamber, a cleaning brush is fixed inside the dust suction chamber, the cleaning brush abuts against the outer wall of the filter cartridge, a mounting frame is fixed to the inner wall of the filter cartridge, and a driving blade is fixed to the mounting frame through a rotating shaft.

The dust is intercepted on the outer wall of the filter cartridge, and at the same time, the flow of air will drive the driving blades to rotate, and the driving blades will drive the filter cartridge to rotate, so that the cleaning brush can be used to clean the filter cartridge to prevent blockage and ensure the normal operation.

[0026] Compared with the prior art, the thermal cutting dust collection device for LCD display glass production has the following advantages:

[0027] 1. When working, after moving the device to the specified position by the moving wheel, the device is connected to the thermal cutting machine by the connecting component. The height of the dust hood and the semicircular telescopic hood can be adjusted by the lifting cylinder, so that the glass is located between the dust hood and the semicircular telescopic hood. The two semicircular tubes are driven by the driving component to move relative to each other, so that the two semicircular tubes wrap the mounting column on which the cutting head is installed on the thermal cutting machine, so that the two semicircular hoods and the two semicircular telescopic hoods wrap the cutting head. When cutting, the two semicircular telescopic hoods are in contact with the upper side of the glass, and the dust hood is in contact with the lower side of the glass, so that the cutting head is located in a relatively closed environment. While cutting, the dust suction device is used for dust suction operation, and the dust suction effect is good, which can greatly reduce the dispersion of dust. At the same time, the structure can be applicable to various types of thermal cutting devices, and the height and installation position of the device can be adjusted according to different models, which greatly improves the practicality of the device.

[0028] 2. During operation, the lifting motor can be used to drive the lifting screw to rotate and adjust the position of the semicircular tube so that the semicircular tube corresponds to the mounting column on which the cutting head is mounted on the thermal cutting machine. The clamping motor can be used to drive the bidirectional screw to rotate so that the two moving blocks move relatively to splice the two semicircular tubes. The inner diameter of the semicircular tube is larger than the outer diameter of the mounting column of the cutting head, thereby leaving an air inlet gap. During operation, the lifting motor can be used to drive the semicircular tube to descend so that the semicircular telescopic cover contacts the upper surface of the glass and can be adjusted in height according to the thickness of the glass. At the same time, the first spring can be compressed so that the semicircular telescopic cover can be in close contact with the glass without damaging the glass.

[0029] 3. Initially, the upper end surface of the resistance cover can be made higher than the lower end surface of the glass. When the glass contacts the guide surface of the resistance cover, the resistance cover is lowered under the inclined guidance of the guide surface, and the second spring is compressed at the same time, so that the resistance cover can be tightly in contact with the lower side of the glass, and there is no need to make extra position adjustments to the resistance cover, which is easy to use.

[0030] 4. During installation, if the cutting machine has a circular tube structure, the fastening column can be extended into the fastening cover, and then the fastening cover can be inserted into the circular tube structure, so that the limit plate can be in contact with the circular tube mechanism, and the electric telescopic rod can be driven. While ensuring that the limit plate is in contact with the circular tube mechanism, the fastening column can be pulled outward, so that the fastening cover can be squeezed by the fastening column, so that the outer surface of the fastening cover can be tightly in contact with the outer wall of the circular tube mechanism, thereby fixing the device. When bolt holes are provided on the cutting machine, the device can be connected and fixed to the cutting machine through the bolt holes by utilizing the cooperation of the mounting plate and the connecting bolts. When a rod-shaped structure is provided on the cutting machine, the rod-shaped structure on the cutting machine can be clamped and fixed by utilizing the cooperation of the arc-shaped connecting seat and the mounting plate. The above-mentioned structure can meet different installation requirements and can be adjusted as needed, with strong practicality.

[0031] 5. During operation, the fan starts, and the dust in the dust hood enters the dust chamber through the dust suction pipe. Then the air is filtered through the filter cartridge and enters the inside of the filter cartridge, and then is discharged through the circular port and the fan. The dust is trapped on the outer wall of the filter cartridge. At the same time, the flow of air will drive the driving blades to rotate, and the driving blades will drive the filter cartridge to rotate, so that the cleaning brush can be used to clean the filter cartridge to prevent blockage and ensure the normal operation. When the dust needs to be cleaned, the dust suction device can be pulled out through the closing plate. It is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

The two semicircular tubes 23 are driven by the driving component to move relative to each other, so that the two semicircular tubes 23 wrap the mounting column on which the cutting head is installed on the thermal cutting machine, so that the two semicircular hoods 15 and the two semicircular telescopic hoods 24 wrap the cutting head. During cutting, the two semicircular telescopic hoods 24 contact the upper side of the glass, and the dust hood 14 contacts the lower side of the glass, so that the cutting head is located in a relatively closed environment.

[0058] An annular groove 50 is provided on the upper side of the slide plate 41, an annular plate 48 is fixed to the lower end of the filter cartridge 43, a socket 49 is fixed to the lower side of the annular plate 48, the socket 49 is inserted into the annular groove 50, an annular guide groove 51 is provided on the inner wall of the annular groove 50, an escape groove 52 is provided on the outer wall of the socket 49, a telescopic column 53 is fixed inside the escape groove 52, a ball 55 is provided on the telescopic column 53, the ball 55 cooperates with the annular guide groove 51, and a fourth spring 54 is fixed between the ball 55 and the escape groove 52.

[0059] By adopting the above structure, during operation, the resistance of the filter cartridge 43 during rotation can be reduced through the cooperation between the ball 55 and the annular guide groove 51, thereby ensuring normal operation. When the filter cartridge 43 needs to be disassembled and installed, it is only necessary to pull the filter cartridge 43 outward with force to retract the ball 55 into the avoidance groove 52, so that the socket 49 is disengaged from the annular groove 50, which is convenient for maintenance and replacement.

[0060] The sealing strip 30 is provided with an adjustment groove 56 on both the front and rear sides. A fifth spring 57 is fixed inside the adjustment groove 56. An adjustment seat 58 is fixed to the other end of the fifth spring 57. The upper and lower ends of the adjustment seat 58 are flush with the sealing strip 30. The cross-section of the adjustment seat 58 is a trapezoidal structure.

[0061] With the above structure, during operation, the width can be adaptively adjusted according to the different cutting gaps, thereby ensuring the sealing effect and meeting the use requirements of different cutting widths.

[0062] The working principle of the present invention is as follows: during operation, after the device is moved to the designated position by the moving wheel 4, if the cutting machine has a circular tube structure, the fastening column 34 can be extended into the fastening cover 36, and then the fastening cover 36 can be inserted into the circular tube structure, so that the limit plate 32 is in contact with the circular tube mechanism, and the electric telescopic rod 31 is driven. While ensuring that the limit plate 32 is in contact with the circular tube mechanism, the fastening column 34 is pulled outward, so that the fastening cover 36 is squeezed by the fastening column 34, so that the outer surface of the fastening cover 36 is in tight contact with the outer wall of the circular tube mechanism, thereby fixing the device. When the cutting machine is provided with bolt holes, the device can be connected and fixed to the cutting machine through the bolt holes by using the cooperation of the mounting plate 37 and the connecting bolts 39. When a rod-shaped structure is provided on the cutting machine, the arc-shaped connecting seat 38 and the mounting plate 37 can be used to clamp and fix the rod-shaped structure on the cutting machine, and then the height of the dust hood 14 and the semicircular telescopic cover 24 can be adjusted by the lifting cylinder 5, so that the glass is located between the dust hood 14 and the semicircular telescopic cover 24. The lifting screw 9 can be driven by the lifting motor 8 to rotate to adjust the position of the semicircular tube 23 so that the semicircular tube 23 corresponds to the mounting column on which the cutting head is mounted on the thermal cutting machine. The two-way screw 20 is driven to rotate by the clamping motor 19 to make the two moving blocks 21 move relative to each other, so that the two semicircular tubes 23 are spliced, so that the two semicircular tubes 23 wrap the mounting column on which the cutting head is mounted on the thermal cutting machine. , so that the two semicircular covers 15 and the two semicircular telescopic covers 24 wrap the cutting head, and the inner diameter of the semicircular tube 23 is larger than the outer diameter of the mounting column of the cutting head, so that an air inlet gap is left, so that when working, the semicircular tube 23 can be driven down by the lifting motor 8, so that the semicircular telescopic cover 24 contacts the upper surface of the glass, and the height can be adjusted according to the thickness of the glass. At the same time, the first spring 25 can be compressed, so that the semicircular telescopic cover 24 can be in close contact with the glass without crushing the glass. When cutting, the two semicircular telescopic covers 24 contact the upper side of the glass, and the dust cover 14 contacts the lower side of the glass, so that the cutting head is located in a relatively closed environment, While cutting, a dust suction device is used to perform dust suction operations, which has a good dust suction effect and can greatly reduce the dispersion of dust. During dust suction, the dust in the dust hood 14 enters the dust suction chamber through the dust suction pipe 16, and then the air is filtered by the filter cartridge 43 and enters the interior of the filter cartridge 43, and then is discharged through the circular port and the fan 47. The dust is trapped on the outer wall of the filter cartridge 43. At the same time, the flow of air will drive the driving blades 46 to rotate, and the driving blades 46 will drive the filter cartridge 43 to rotate, so that the cleaning brush 44 can be used to clean the filter cartridge 43. At the same time, this structure can be applicable to various types of thermal cutting devices, and the height and installation position of the device can be adjusted according to different models, which greatly improves the practicability of the device.

[0063] In summary, by disposing the semicircular cover 15, the abutment cover 22, the driving assembly and other structures, a closed dust collection operation is achieved, and the use range of the dust collection device is improved.
