Painting system of damaged vehicle and control method of the system {omitted}

The present invention relates to a paint system for a damaged vehicle. More particularly, the present invention relates to a control method for automating a painting system of a damaged vehicle.

Recently, the demand for automobile safety has been continuously increasing due to the rapid increase in accidents due to the development of the domestic automobile industry and the increase in the number of vehicles. In particular, damage to the vehicle occurs due to external factors such as collision, rollover, fire, flooding, and the like.

As of the end of 2013, there are about 5,300 companies in the domestic auto repair paint industry. Repairs are often made due to differences in color between the paint and the repair paint. For example, if the color difference between the existing surface and the repair paint surface is different by 20% or more, it is classified as a work break and repainted.

Most automobile repair paint companies use finished product cans. Because of the variety of car colors, many cans of finished products are in stock. In addition, it is very difficult to repair and repair many cans of finished products that are held by the worker in the inventory, and the color matching of finished cans is also more than 20% It is very high. It is estimated that the paint of finished cans, especially those left over, is discarded by more than 30% every year

Korean Patent No. 10-0673343, which is a prior art, has a problem that it is very difficult to use it in the field of maintenance painters. The first is very expensive. In addition, analysis and machining of specimen data is very time consuming. In addition, since the color deviation of the colorimetric data of the repair painting vehicle is different by 20% or more, it is necessary to perform the color adjustment, but the adjustment time is required to be 1 st, 2 nd, 3 rd or more and the process takes a long time. It is necessary to perform coloring process and require high technology. Therefore, there is a limit to use by general maintenance painting worker.

Therefore, a more automated painting system and a control method of the system are required so as to be less dependent on the skill of the operator.

1 shows an example of a painting system for repairing a car according to the present invention.

1, the painting system 100 includes at least one of a color sensing unit 110, a transceiver unit 120, a controller 130, a painting unit 140, a drying booth 150, and a server 160 .

The color sensing unit 110 includes a polygonal side colorimetric system 112 and a micro luminosity measurement system 114. The polyhedral colorimeter 112 obtains color data of a reference color by measuring a coating film of a reference color that matches the painting of the paint by color mixing with a colorimetric system. The micro luminous intensity measuring instrument 114 measures the coating film of the reference color which matches the painting of the painting by color mixing with a micro luminous intensity measuring instrument to obtain micro luminous intensity data of the reference color. Accordingly, the color sensing unit 110 scans the vehicle and acquires measurement paint data of the vehicle.

The transmission / reception unit 120 receives the normal painting color data of the vehicle from the server 160 when the vehicle is in stock. The normal painting data according to the model name and color of the released vehicles are stored in the server and receive this data. A sample database is constructed based on the received normal painting data. Information about the models and colors of the latest vehicles can be continuously updated on the server, and the painting system connected to the server can always keep up to date information.

The controller 130 compares the measured painting data with the normal painting color data received from the server 160 to determine an optimum color matching table. At this time, the control unit 130 determines a plurality of paint formulations, color data corresponding to each paint combination, microphysiological data, and color data of a plurality of primary color paints and microphysical emotion characteristic data. That is, the control unit 130 compares the color data of the reference color and the microvargraphic data with the color data and the microvolatilization data corresponding to the paint combination received from the server, and stores the color of the registered paint composition and the micro- The degree of registration of the senses is indexed to select the candidate paint formulation.

The control unit 130 determines each color number corresponding to each of the plurality of registered paint combinations and displays it on the display. In this way, the operator can work according to the determined paint composition.

The control unit 130 compares the painted data of the vehicle and the normal painted data of the received vehicle to determine if the painted data of the vehicle is less than or equal to a predetermined threshold value or more than a value received from the server, The state is judged as normal, and it is judged that the part is no longer required to be painted.

The control unit 130 selects at least one of the color combination data of the paint combination and the microphysiological data among the color numbers equal to the preset color number of the reference color. The control unit 130 compares the color data of the selected paint combination and the microvargraph data with the color data of the reference color and the microvargraph data. The control unit 130 exponents the degree of matching of the color and micro-brilliance of the selected paint combination to select a candidate paint combination.

The painting unit 140 operates to paint the vehicle on the basis of the color data determined by the control unit 130, the microphysical data, or the paint combination. Also, the paint unit 140 operates to paint the vehicle on the basis of whether or not the paint condition of the vehicle determined by the control unit 130 is a normal condition. For example, the painting unit 140 can display the number of the painting can on the display. As another example, the painting unit 140 outputs the painting can determined by the control unit 130 among the painting candles.

For example, the color sensing unit 110 scans the vehicle after the coloring unit 140 has painted and re-measures the coloring information.

The control unit 130 determines each color number corresponding to each of a plurality of registered paint combinations and displays it on the display. The coloring unit 140 displays each color number corresponding to the coloring combination to be painted on the display do. The external manager can grasp whether the color determined by the controller 130 and the color painted in the coloring unit 140 are the same.

The vehicle having completed painting moves to the drying booth 150. The drying booth 150 includes a booth body, an air blowing device installed outside the booth body for forcibly injecting air into the booth body, and an air blowing device installed outside the booth body opposite to the blowing device, And an exhaust device for forcibly discharging it to the outside. The detailed embodiment of the drying booth 150 will be described in more detail in FIGS.

2 shows an example of a method of controlling a color sensing unit and a control unit of a painting system according to the present invention.

Referring to FIG. 2, in the painting system, the coating film of the reference color matching the painting of the painting material by coloring is measured with a colorimeter to obtain color data of the reference color (S210). The color reference data of the paint film to be painted is measured with a polygonal colorimetric system to obtain color data under various angle conditions.

Subsequently, the coating film of the reference color is measured with a micro luminous intensity measuring instrument to obtain microviolet sensitivity data of the reference color (S220). The micro luminous intensity measuring device may include a light irradiating device, a CCD camera which photographs the coated film surface with light at an angle at which the irradiated light does not enter and forms an image, and an image analyzing device connected to the CCD camera to analyze the image have.

Next, the micro color brightness data of the reference color and the micro color brightness data of the reference color are compared with the color data and the micro brightness data corresponding to the paint combination received from the server, and the degree of matching of the color of the paint composition and the micro- And the candidate paint combination is selected (S230). The selection of the candidate paint combination takes into consideration the degree of matching of the color with the reference color and the microphotosensibility, and the compounding data.

3 is a flowchart showing an example of a coloring process of a colored portion of the system according to the present invention.

Referring to FIG. 3, the paint part paints based on the candidate paint combination determined by the control part.

First, a portion corresponding to an area three times larger than the scratch portion is pretreated with a compound around the damaged scratch portion on the outside of the automobile (S310). Foreign materials such as collars or paint marks, which are harmful substances contaminating the damaged surface of the damaged part, are removed, and the previously applied coating agent or the like is removed to facilitate the attachment of the paint described later. The reason for compounding the portion corresponding to the area three times larger than the scratch portion is to minimize the display of the boundary line between the portion to be painted and the portion to be painted.

Thereafter, the paint part paints based on the candidate paint combination determined by the control part.

More specifically, the same paint as the exterior color of the vehicle is sprayed on the surface of the compounded surface in the absence of light (for example, undercoating paint), followed by drying at room temperature for 5 to 20 minutes (S320). Subsequently, urethane thinner is sprayed onto the outer portion excluding the damaged central portion of the scratch (S330). When the undercoat paint is applied, the scattered portion melts and the boundary between the painted portion and the non-painted portion disappears to the extent that it is difficult to visually recognize, and at the same time, the surface of the undercoat becomes rough by spraying. This is also referred to as a paint surface treatment process. Subsequently, an upper coat paint, which is a transparent transparent paint, is sprayed on the surface of the undercoat paint and is naturally dried at room temperature for 5 to 20 minutes (S340). It corresponds to the top coat coating process which treats the matte undercoat paint with gloss. Subsequently, a mixture of a glossy transparent coating material used in the top coating and a diluent (e.g., thinner) at a ratio of 1: 1 to 1:10 is sprayed and applied (S350). The mixture serves to firmly adhere the top coating and the under coating. And the durability is improved. When the transparent paint and the diluent (thinner) are confined at a ratio of 1: 1 to 1:10, the viscosity is too high to solve the problem that uniform application is difficult and the viscosity is too low to solve the problem of flowability.

Subsequently, the coated portion, in which the mixture is sequentially applied, is dried (S360) for 5 to 15 minutes using an infrared drier maintaining a temperature of 60 to 80 ° C. Dried in the order in which they are applied from the inside (i.e., in the order of bottom, top, and mixture), and are firmly attached to the vehicle. If the drying temperature of the infrared dryer is below 60 ° C, it takes a long time to dry. If it is higher than 80 ° C, it may cause cracking due to rapid drying.

Subsequently, the surface of the mixture is evenly rubbed by using a water-resistant paper (S370). The boundary between the painted portion and the non-painted portion disappears to the extent that it can not be visually recognized, and the surface of the mixture becomes smooth.

Then, the compound was applied to the surface of the mixture, and then polished for 2 to 3 minutes using a polisher to give a primary gloss, followed by applying a polishing agent, and then polishing with a polishing machine for 2 to 3 minutes to adjust the gloss The height is subjected to secondary gloss (S380). The boundary between the painted portion and the non-painted portion does not appear at all.

Next, a water glass coating agent is applied to the surface of the mixture and cured at room temperature for 2 to 3 minutes to form a water glass coating layer, and then the surface of the water glass coating layer is wiped with a microfiber towel (S390). The waterglass coating layer reflects a part of the sunlight to prevent discoloration and decolorization of the coating part from ultraviolet rays, and enhances the durability by preventing the scratch by increasing the strength.

The lower air discharge passage 103 discharges air, paints, dust and the like falling from the space inside the drying booth 150 to the outside of the drying booth 150. The lower air discharge passage 103 discharges air, paints, dust and the like from the inner bottom surface of the drying booth 150 to the outside through one external side of the drying booth 150. The lower air discharge passage 103 forcibly discharges air, paint, dust, and the like in the bottom of the drying booth 150 to the outside by an air cleaning device 600 installed on the outer side of the drying booth 150.

The upper air discharge passage 104 discharges air, paint, and the like, which spill upward in the drying booth 150, to the outside. The upper air discharge passage 104 forcibly discharges air, paint, dust, etc. rising upward in the drying booth 150 by an air cleaning device 600 installed on the outer side of the drying booth 150.

The drying booth 150 surrounds the plurality of through holes 102 on the upper surface of the drying booth 150 to block the air supplied to the through holes 102 from mixing with the air rising upward in the drying booth 150, And a lower end of the partition wall 105 is closed by a plate-like flat plate filter 106. The flat plate filter 106 filters dust in the air supplied into the drying booth 150 through the filter 300.

The fixed frame 200 is inserted and fixed in the through-hole 102 in a hollow shape having open top and bottom. The fixed frame 200 fixes the filter 300 therein so that the filter 300 is positioned in the through hole 102. The filter 300 is fixed to the fixed frame 200 to filter out foreign matter in the air supplied through the through hole 102. The filter 300 is fixed to the fixed frame 200 and filters out foreign matter or dust in the air passing through the through hole 102 of the drying booth 150. The filter 300 may be detached from the fixed frame 200 according to a user's selection or use period and may be replaced.

The air passage net 400 is installed on the bottom surface of the drying booth 150 and controls the air supply amount so that the air is evenly distributed to the lower air discharge passage 103. A grating 500 supporting a load of an article, a vehicle, or the like is covered above the air passage net 400. The air passage net 400 is formed with a plurality of passage holes 401 through which the air falling downward in the drying booth 150 passes through the lower air discharge passage 103, 401 are formed to be relatively smaller toward the lower air discharge passage 103 communicating with the outside at one end. The through hole 401 gradually decreases in the direction of the door 101 toward the direction in which the air purifier 600 is installed so that the air flow intensity forcibly sucked in the air purifier 600 is reduced, So that they are uniformly distributed over the net 400. The passage hole 401 is preferably a rectangular shape, and the shape of the passage hole 401 may be variously changed according to the user's selection.

The air purifier 600 is installed on one side of the drying booth 150 and guides the air to the outside through the lower air discharge passage 103 and the upper air discharge passage 104.

The grating 500 covers the upper surface of the air passage net 400 in the form of a plate and forms a plurality of through holes 501 on the upper surface thereof to support and support the article or automobile contained in the drying booth 150. The grating 500 is preferably formed of a material that can support the article or the car.

5 is a flowchart showing an example of a method of controlling a drying booth of a painting system according to the present invention.

5, the drying booth 150 according to the present invention has the door 101 opened to allow a vehicle or an article to enter the space in the drying booth 150, 101 to close the open portion of the drying booth 150 so that the space in the drying booth 150 is blocked from the outside.

Subsequently, the inner space of the drying booth 150 becomes airtight, and a paint or an operator paints the article or the vehicle circumferential surface by spraying or spraying the article or the vehicle stored in the drying booth 150. Here, an article, a vehicle, or the like is supported on the grating 500 to prevent a load such as an article or a vehicle from being applied to the air passage net 400. Particularly, the drying booth 150 allows the air falling freely through the through-hole 102 to pass through the inner space, so that the air is uniformly distributed in the inner space, and the air is contacted with the object or the paint painted on the vehicle The paint surface is dried.

The air falling freely through the through hole 102 passes through the filter 300 fixed to the fixed frame 200 to remove foreign matter or dust and the like, and through the through hole 102, (150).

The air that has passed through the filter 300 is blocked by the partition wall 105 and is prevented from spreading in all directions and the dust is filtered through the flat plate filter 106 in this state to enter the predetermined space in the drying booth 150 Falls.

The air supplied into the drying booth 150 is brought into contact with the object or the paint painted on the vehicle, and the paint scattered during painting or the dust or the like remaining in the space in the drying booth fall downward, And then flows into the air passage net 400.

Air, paints and dust falling downward in the drying booth 150 pass through the through hole 501 of the grating 500 and the through hole 401 of the air passage net 400, And is forced to be sucked into the air purifying device (600).

At this time, the air, paint, dust, and the like sucked by the forced suction force of the air purifier 600 are forced to be sucked into the air purifier 600 through the through hole 401 gradually becoming smaller from one end to the other end So that a uniform suction pressure is generated on the bottom surface of the drying booth 150.

The suction pressure applied to the lower air discharge passage 103 in the direction in which the air purifier 600 is installed is formed to be relatively larger than the suction pressure applied to the air discharge passage 103 on the opposite side of the air discharge passage 103, The size of the through hole 401 on the side of the door 401 is set to be larger than the size of the through hole 401 on the side of the door 401 in the direction in which the air purifier 600 is installed do. The amount of air sucked into the passage hole 401 in the direction in which the air purifier 600 is installed is relatively smaller than the amount of air sucked into the opposite passage hole 401, The suction pressure becomes uniform.

The air passing through the through hole 102 is freely dropped so as to be uniformly distributed in the drying booth 150 and is uniformly discharged to the lower air discharge passage 103 through the air passage net 400, Uniform pressure is applied to the upper and lower spaces in the drying chamber 150 to prevent vapors from being generated in the space inside the drying booth 150, thereby preventing the paint on the article or automobile paint surface from scattering in the space in the drying booth.

When air spray is used in the drying booth 150, air and paint sprayed at a high speed are divided into upper and lower parts in a state of colliding against the wall surface of the drying booth 150, Is discharged to the outside through the upper air discharge passage (104).

The air and the paint rising upward in the drying booth 150 are blocked by the partition wall 105 and the air pressure supplied to the drying booth 100 is applied to the inner wall surface of the drying booth 100, And is discharged to the outside through the upper air discharge passage 104. [

Accordingly, the air and the paint that rise above the drying booth 150 are not mixed with the air supplied into the drying booth 150 without being turned downward, and the air supplied into the drying booth 150 and the drying booth 150 So that no vortex is generated.

When the state of the filter 300 is checked and is desired to be replaced, the filter 300 is detached from the through-hole 102, and the filter 300, which is fixedly inserted into the fixed- The fixing frame 200 can be reattached to the through hole 102 after replacing the fixing frame 200. [

Natural air is freely dropped into the drying booth 150 to distribute the air evenly in the drying booth 150 and the uniform pressure is applied to the bottom of the drying booth 150 by the air passage net 400. Natural air is freely dropped through the through holes 102 of the drying booth 150 to distribute the air evenly throughout the entire space in the drying booth 150 and to form air passages 400 The air and the paint in the drying booth 150 are discharged rapidly and the air in the drying booth 150 is uniformly discharged evenly by the supply amount and the discharge amount of the air, The air is prevented from being swirled due to the generation of the vortex so that the foreign matter or dust in the air does not sink to the conductor and the air is uniformly distributed in the article or the vehicle The applied paint is brought into contact with the air to be uniformly dried, and the coated surface of the article or the vehicle is uniformly dried.

6 shows an example of a heat treatment apparatus provided in the drying booth 150 according to the present invention.

The stand 1 has a support base 11 supported on the ground and a pipe and a lower end fixedly mounted on the upper surface of the support base 11. The stand 1 has a first fixing hole 121 A first vertical beam 12 having one end fixed to the first fixing hole 121 and a first fixing knob 122 corresponding to the first fixing hole 121 and a second vertical beam 12 having an outer surface corresponding to an inner end surface of the first vertical beam 12, A first vertical beam 13 having a shape of a second vertical beam 13 and a pipe inserted from the upper part of the first vertical beam 12 and having a first end coupled to the upper end of the second vertical beam 13 by a first hinge 141, A pneumatic cylinder 144 slantingly connected by the second and third hinges 142 and 143 is provided between the front surface of the second vertical beam 13 adjacent to the bottom surface and the pneumatic cylinder 144 horizontally penetrating from one surface adjacent to the front end A second fixing hole 145 formed at one end thereof and a second fixing hand 146 corresponding to the second fixing hole 145, The first horizontal bar 14 has a first horizontal bar 14 and an outer end face corresponding to an inner end face of the first horizontal bar 14 and is inserted from the front face of the first horizontal bar 14, And a second horizontal bar 15 on which the first horizontal bar 151 is formed.

The lamp module 2 includes a lamp 21 and a reflection plate 22 formed on the front surface thereof and is formed by several alignments and is rotatably supported by a vertical hinge module 3 between the lamp module 2 and an adjacent lamp module 2. [ .

7 shows another example of the drying booth of the painting system according to the present invention.

7, a drying booth 150, in which the parts of the vehicle achieve drying in a state where the four sides are closed and the inside is warmed by using a plurality of halogen lamps 31, is connected to the open inlet door of the drying booth 100, The upper end conveyor 10 is arranged in various shapes so as to form a straight line section A and a curved section B from the upper end 32 to the outflow door 33 on the other side. Stage interlocking carriage 60, a two-stage interlocking carriage 70, and a fixed interlocking carriage 80 that can be arbitrarily arranged at a predetermined interval on the upper end of the conveyor 10, (K) for maximizing the vertical space of the vehicle. A plurality of exhaust holes 22 formed at the bottom of the drying booth 150 at regular intervals and an exhaust space 21 communicating with the exhaust holes 22 to form a constant space at the bottom are formed, The communication pipe 23 communicating with the space 21 is piped and communicated with the air purifying device 50 on the other side. The air filtered through the air purifier 50 flows into the ceiling supply space 25 having a plurality of air supply holes 27 through the inflow pipe 24.

The drying booth 150 of the painting system is a system for drying the parts 1 of the vehicle while always conveying them in the drying booth 150.

The drying booth 150 is provided with a conveyor 10 in which a linear section A and a curved section B are arranged. The advantage of such a drying booth 150 is that a drying booth 150 having only a straight line section A is required to have a large area of the drying booth 150. As in the present invention, The conveyor 10, which is twisted around the line section A, can dry a larger amount of parts even if applied to a small-sized drying booth 150. When the conveyor 10 moving in a line in the straight line section A is folded into the curve section B, overlapping portions are generated. Particularly, since the work plates 61, 71 and 81 for drying large parts as compared with the conveyor 10 are wide, they stop moving the conveyor 10 when they overlap each other in the curved section B.

The present invention solves this problem by providing work plates (61, 71, 81) having different levels from each other. In the curved section B where traffic jam can occur, some working plates 61, 71, and 81 are raised to separate the space actually occupied.

The coating system warms up the drying booth 150 without hot air drying. When hot air is applied to the parts of the vehicle, unevenness is generated in the paint due to the force of the wind, and sometimes a phenomenon of cracking occurs. Particularly in the case of painting with hibernation, this phenomenon is common, but the high temperature drying method using light is applied instead of the hot air drying method

A halogen lamp 31 emitting a high heat is installed entirely inside the wall surface to always emit high-temperature heat through light energy. The droplets of the coloring material existing in accordance with evaporation or vaporization generated during drying through the air purifying device 50 are removed. The air purifying device 50 is operated before performing or performing the drying process in the drying booth 150.

That is, there are a plurality of exhaust holes 22 formed at the bottom, and an exhaust space 21 having a constant area is provided at the lower end of the exhaust hole 22. The air in the drying booth 150 flowing into the exhaust space 21 at the time of sucking is sucked into the communicating tube 23 because the communicating tube 23 communicates with one side of the exhausting space 21. [ The contaminated air in the drying booth 150 sucked into the communicating tube 23 passes through the air purifying device 50 formed at one side of the drying booth 150 and is filtered. The filtering method can be passed through a multi-layered filter or passed through water droplets of small particles to improve cleanliness. The clean air is circulated again and flows into the air inflow space 25 formed in the ceiling through the inflow pipe 24. Since a large number of inflow holes 27 are formed in the ceiling as shown in the drawing, the inflow air smoothly enters into the drying booth 150 without generating any additional wind. In the present invention, air circulation is achieved in such a simple and natural manner, and a large amount of automobile parts are dried.

The conveyor 10 includes a rail plate portion 12 which extends horizontally so as to close the upper opening portion in the left and right direction of the fixed region, A plurality of sprockets 13 mounted on the inner side and the side surface of the frame 11 at regular intervals and a chain 14 wound around the outer peripheral surface of the sprocket 13, A movable support panel 15 is formed which is coupled to the chain 14 in a detachable manner at a predetermined interval to allow the chain 14 to move along with the frame 10 while being interlocked. And a coupling protrusion 16 protruding from the upper portion of the movable support panel 15 so as to be coupled to the movable support panel 15 in a detachable manner without shaking, In the drying booth (150).

The movable support panel 15, which is detachably coupled to the chain 14, is mounted on a horizontal rail plate 12 protruding from the frame 10, A folding guide 17 for moving the movable support panel 15 horizontally in accordance with the moving direction of the chain 14 is provided so as to be able to move without bearing the side surface of the plate portion 12, I have.

The end of the bending guide 17 is inserted into the chain 13 and can be inserted therein. The folding guide 17 protrudes from the lower end of the movable support panel 15 in a bent form so as to protrude in the left and right direction so that the movable support panel 15 can substantially receive the same force.

The folding structure of the folding guide 17 is substantially the same as the guider moving around the guide rail 90 so as to wrap around the side of the uppermost rail plate 12 of the frame 11, So that they can be moved by the same distance along the moving direction of the chain 13. Of course, since the bending guide member 17 exists in the form of wrapping the outer circumferential surface of the rail plate portion 12 as described above, smooth and smooth movement can be achieved without interlocking in the left-right direction or the vertical direction while being moved.

The moving truck K according to the present invention is connected to the conveyor 10 at regular intervals in the order of the fixed interlock truck 80, the two-stage interlock truck 70, A guide rail 90 composed of a rising section 91, a horizontal section 92 and a descending section 93 rising upward from the frame 10 is formed in the curved section B of the conveyor 10 Stage interlocking carriage 70 and the second-stage interlocking carriage 80 in the curve section B can be moved upward by a predetermined height.

In the present invention, the working plates (61, 71, 81) have different heights. The conveyor 10 in which the fixed interlocking carriage 80, the two-stage interlocking carriage 70 and the one-stage interlocking carriage 60 are sequentially connected is provided in forming the moving carriage K. The level of the fixed interlocking carriage 80 can not be interlocked with the work plate 81 in the vertical direction because the level of the fixed interlocking carriage 80 is always fixed, Of the total population. Of course, when the first-stage interlocking carriage 60 raises its level by raising its working plate 61, it maintains a level twice as high as the level of the working plate 81 of the fixed interlocking carriage 80. On the other hand, the level of the two-stage interlocking carriage 70 work plate 71 is twice as high as the level of the work plate 81 of the first-stage interlocking carriage 60 and the fixed interlocking carriage 80 at a downward point Lt; / RTI > That is, the same level as the level of the rising point working plate 71 of the first stage interlocking carriage 70. However, when entering into the curve section B, the working plate 71 of the two-stage interlocking carriage 70 ascends to secure the position of the highest point.
