Description

Technical Field

[0001] The present application relates to the technical field of glass production and processing, and specifically discloses a spraying device for architectural glass. Background Art

[0002] In order to enhance the wear resistance, corrosion resistance and impact resistance of architectural glass to adapt to environments such as building facades and solar panels that need to withstand high temperatures, abrasion or harsh climates, it is usually necessary to spray a coating on the surface of architectural glass. At the same time, the surface of the glass can be modified through film coating spraying, endowing the architectural glass with the properties of ultraviolet resistance and low radiation.

[0003] An automated spraying device is a mechanical device that replaces traditional manual spraying. It has advantages such as low labor intensity and high spraying efficiency. Currently, the spraying device usually uses a conveyor to transport architectural glass, and then drives a spray gun to move along the surface of the architectural glass through a servo mechanism, so as to achieve the purpose of spraying the entire surface of the architectural glass. However, due to the conveyor and the servo mechanism being independent of each other, the phenomenon of displacement and misalignment of the architectural glass is likely to occur during the spraying process, resulting in missed spraying and wrong spraying, thus affecting the uniformity of the sprayed coating, that is, affecting the finished product quality of the architectural glass; and during the spraying process of the spray gun on the architectural glass, the coating will inevitably be sprayed by the spray gun onto the conveyor and the clamping mechanism located at the edge of the architectural glass. After several reciprocations, the thickness of the conveyor and the clamping mechanism will increase, affecting the normal use performance of the conveyor and the clamping mechanism, and at the same time reducing the accuracy of the conveyor and the clamping mechanism, and even causing the architectural glass to be stuck, resulting in damage to the architectural glass. Therefore, in view of this, the present invention provides a spraying device for architectural glass to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that during the traditional spraying process of architectural glass, the architectural glass is prone to displacement and misalignment, resulting in missed spraying and wrong spraying, which affects the uniformity of the sprayed coating.

[0005] To achieve the above purpose, the basic solution of the present invention provides a spraying device for architectural glass, including:

[0006] A conveying assembly, including symmetrically arranged brackets, rollers arranged between the brackets, and pressure rollers respectively arranged on the brackets, and synchronous transmission connections are provided between adjacent pressure rollers;

[0007] A spraying assembly, including a reciprocating lead screw arranged above the brackets, a sliding seat threadedly connected to the reciprocating lead screw, and a spray gun arranged on the sliding seat, and guide rods for the sliding seat to slide are arranged between the brackets;

[0008] The driving assembly includes a power component, a sector gear driven by the power component to rotate, a conveying driving gear and a spraying driving gear respectively meshed with the sector gear. The conveying driving gear is in transmission connection with the reciprocating lead screw, and the spraying driving gear is in transmission connection with one of the pressure rollers. Electric connection pieces are provided on the spraying driving gear and the sector gear, which can be in electrical contact with each other and control the start of the spray gun.

[0009] The principle and effect of this basic solution are as follows:

[0010] Compared with the prior art, the present invention uses the power component to drive the continuous operation of the sector gear, so that the conveying driving gear and the spraying driving gear are respectively alternately meshed with the sector gear. The conveying driving gear drives the pressure roller to rotate, and the spraying driving gear drives the reciprocating lead screw to rotate alternately, so as to achieve the purpose of alternately moving and spraying the building glass. At the same time, during the meshing process of the spraying driving gear and the sector gear, the electric connection piece is also conducted to automatically control the opening of the spray gun, and the spray gun is controlled to close during the meshing process of the conveying driving gear and the sector gear, effectively avoiding the problems of missed spraying and wrong spraying that affect the uniformity of the spraying coating.

[0011] Further, it further includes a cleaning assembly. The cleaning assembly includes a fixing ring provided at the top of the pressure roller near the nozzle, a plurality of water injection holes provided on the side wall of the fixing ring, a water passage penetrating through the fixing ring and the inside of the pressure roller and communicating with the water injection holes, and a water inlet pipe communicating with the end of the water passage. A recovery tank is provided at the bottom of the bracket below the fixing ring, and a water permeable hole communicating with the recovery tank is provided on the bracket. Through the water inlet pipe, the water passage and the water injection holes, the water flows along the water injection holes to the surface of the pressure roller and finally flows to the recovery tank through the water permeable hole for recovery, which can clean the paint sprayed on the pressure roller in real time and avoid the problem that the long-term accumulation of paint affects the conveying accuracy of the pressure roller.

[0012] Further, the cleaning assembly further includes fixing strips provided on both sides of the pressure roller near the nozzle of the bracket, inner matching grooves provided on the side walls of the fixing strips, and absorbent cotton provided in the inner matching grooves. The bottom of the inner matching groove communicates with the water permeable hole. So that during the rotation of the pressure roller, the absorbent cotton contacts the surface of the pressure roller to adsorb the water stains on the surface of the pressure roller, avoiding the water stains splashing onto the surface of the building glass and affecting the spraying effect of the building glass.

[0013] Further, a pressing plate is slidably connected to the inner wall of the inner matching groove. A guide hole is provided on one side of the inner matching groove close to the sliding seat, and a push rod capable of extending into the guide hole and pushing the pressing plate is provided on the sliding seat. So as to drive the push rod to push the pressing plate by the reciprocating movement of the sliding seat, so that the pressing plate squeezes the absorbent cotton to squeeze out the excess water and flow through the water permeable hole to the recovery tank for centralized recovery.

[0014] Furthermore, the bottom of the pressure roller near the nozzle is provided with an outer ring groove and an inner ring groove, the outer ring groove is slidably connected with a plurality of connecting strips, a rotating disk is provided in the inner ring groove, an elastic layer is filled between the rotating disk and the inner wall of the inner ring groove, and each connecting strip is provided with a connecting rod that penetrates the pressure roller and is connected to the rotating disk, and the water channel includes a fixed channel provided inside the pressure roller and an adjustment channel provided on the rotating disk and connected to the fixed channel, so as to automatically adjust the connection and disconnection of the water channel according to whether there is architectural glass conveyed at the position of the pressure roller.

[0015] Furthermore, the connecting strip is obliquely arranged on the side wall of the outer ring groove, and at least two connecting rods are arranged on the same connecting strip, so that during the conveying process of the building glass, the connecting strip can be squeezed to push the connecting rod and the turntable to move.

[0016] Furthermore, the water injection hole is arranged on the side wall of the fixing ring away from the spray gun, a water guide cavity is arranged inside the fixing ring, a through groove communicating with the water guide cavity is arranged at the bottom of the fixing ring, and the fixing channel includes a main channel communicating with the adjustment channel and a branch channel arranged at the end of the main channel and extending to the top end surface of the pressure roller and located below the fixing ring, so that during the rotation of the pressure roller, the fixing channel can continuously maintain communication with the water injection hole.

[0017] Furthermore, when the building glass contacts and squeezes the connecting strip, the adjusting channel is separated from the fixed channel, and when the connecting strip does not contact the building glass, the adjusting channel is connected to the fixed channel. When there is building glass at the location of the pressure roller, the water injection hole does not spray water to avoid the water flow affecting the spraying effect of the building glass, and when there is no building glass at the location of the pressure roller, the water injection hole sprays water to clean the pressure roller.

[0018] Based on the same inventive concept, the present invention discloses a spraying method for architectural glass, including using the above-mentioned spraying device to spray the building.

[0019] Further, the steps of using the above-mentioned spraying device to spray the building are as follows:

[0020] Step S1, placing the architectural glass to be sprayed on the loading end of the conveying assembly;

[0021] Step S2, the driving mechanism drives the conveying driving gear and the spraying driving gear to operate intermittently and alternately, so that the pressure roller intermittently drives the building glass to move, and the reciprocating screw intermittently drives the spray gun to move, thereby completing the spraying of the glass surface;

[0022] Step S3, taking the sprayed architectural glass from the unloading end of the conveying assembly.

[0023] This method solves the problem that during the traditional spraying process of architectural glass, the architectural glass is prone to displacement and misalignment, resulting in missed spraying and incorrect spraying, which affects the uniformity of the sprayed coating.

[0040] As Figure 5 shown, an outer ring groove and an inner ring groove are arranged at the bottom of the pressure roller 2 near the nozzle. A structure for supporting the support ring 26 is formed between the outer ring groove and the inner ring groove. A plurality of connecting strips 20 are inclined and slidably connected to the outer ring groove. A turntable 21 is arranged in the inner ring groove.

[0044] Step S1, the architectural glass 4 is transported to the loading end of the conveying component by means of manual handling or robotic arm clamping. Both sides of the architectural glass 4 are respectively located on the trays 3 on both sides and are in contact with the pressing roller 2.

[0045] Step S2, the power component drives the sector gear 12 to continuously operate, so that the conveying drive gear 14 and the spraying drive gear 13 respectively alternately mesh with the sector gear 12. That is, the conveying drive gear 14 drives the pressing roller 2 to rotate, and the spraying drive gear 13 drives the reciprocating lead screw 5 to rotate to drive the spray gun 9 to move alternately. And when the spraying drive gear 13 meshes with the sector gear 12, the electrical connection pieces on the connecting ring 16 and the connecting ring 15 are also connected to each other, turning on one of the solenoid valves of the spray gun 9. When the spraying drive gear 13 disengages from the sector gear 12, the electrical connection pieces on the connecting ring 16 and the connecting ring 15 are disconnected, so as to automatically control the opening and closing of the spray gun 9, achieving the purpose of alternately moving and spraying the architectural glass 4; after the architectural glass 4 is sprayed, the other solenoid valve of the spray gun 9 is closed to keep the spray gun 9 in a shutdown state; and during this process, when there is architectural glass 4 at the position of the pressing roller 2, the water injection hole does not sprinkle water to avoid the water flow affecting the spraying effect of the architectural glass 4, and when there is no architectural glass 4 at the position of the pressing roller 2, the water injection hole sprinkles water to clean the pressing roller 2.

[0046] Step S3, the sprayed architectural glass 4 is taken off from the unloading end of the conveying component by means of manual handling or robotic arm clamping.

[0047] It can be seen that this embodiment can effectively avoid the problems of missed spraying and mis-spraying affecting the uniformity of the spraying coating, and at the same time can clean the paint sprayed on the pressing roller 2 in real time to avoid the problem that the long-term accumulation of paint affects the conveying accuracy of the pressing roller 2.

[0048] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any indirect modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
