The bracket 41 cooperates, and the clamping assembly 5 is installed on the connecting piece 45. The clamping assembly 5 is used to clamp the components on the worktable 2. The electric push rod 44 can push the connecting piece 45 to move upward, so that the connecting piece 45 drives the clamping assembly 5 to flip over with the cooperation of the lifting bracket 41, and turns over the components on the clamping assembly 5. The spraying assembly 6 includes an atomizing nozzle 61 for spraying the components. The atomizing nozzle 61 is cooperated with the driving assembly 7.

The ventilation assembly 9 is installed in the spraying room 11. The ventilation assembly 9 can discharge harmful substances floating in the spraying room 11 after spraying.

[0020] When in use, first move the stage 2 toward the door of the spray cabinet 1 to facilitate the operator to place the components. When the stage 2 moves to the side of the door of the spray cabinet 1, stop the movement of the stage 2, open the door of the spray cabinet 1, place the components to be sprayed on the stage 2, and clamp the two ends of the components with the clamping assembly 5. At this time, the output shaft of the electric push rod 44 is in a retracted state, and its connecting piece 45 is located at the lower end of the lifting bracket 41. The atomizing nozzle 61 is located on one side above the stage 2 and is aligned with the inward end of the component. After the clamping assembly 5 clamps the component, the door is closed and the spraying work is started. The atomizing nozzle 61 sprays the paint onto the upper surface of the component. At the same time, the stage 2 drives the component to move into the spraying room 11 , so that the outward end of the component moves under the atomizing nozzle 61. During the movement of the stage 2, the driving component 7 drives the atomizing nozzle 61 to move toward the other side of the stage 2. After the atomizing nozzle 61 moves to the other side of the stage 2, the driving component 7 drives the atomizing nozzle 61 back to the original side. When the stage 2 delivers the outward end of the component under the atomizing nozzle 61, the driving component 7 has driven the atomizing nozzle 61 to reciprocate multiple times, thereby evenly coating the upper surface of the component. Subsequently, the electric push rod 44 extends its output shaft to push the connecting member 45 and the clamping assembly 5 thereon upward, so that the lower surface of the component is separated from the stage 2, and during the rising process, the connecting member 45 cooperates with the lifting bracket 41 The clamping assembly 5 and the parts thereon are driven to rotate 180 degrees, thereby turning the parts over so that the lower surface of the parts faces the atomizing nozzle 61. After the parts are turned over, the electric push rod 44 stops working. At this time, the connecting piece 45 is located at the upper end of the lifting bracket 41. At the same time, the stage 2 drives the parts to move toward the cabinet door. During the movement of the parts, the driving assembly 7 drives the atomizing nozzle 61 to reciprocate and spray the lower surface of the parts. When the stage 2 moves the parts back to the cabinet door, the atomizing nozzle 61 completes the spraying of the parts. At this time, the hot air blower 8 is started to deliver hot air to the spraying room 11 to heat the air in the spraying room 11, thereby drying the parts that have just been sprayed. In this process, the parts lifted by the electric push rod 44 are The components can be fully in contact with the hot air in the spray chamber 11, thereby accelerating the drying speed. After the components are dried, the hot air blower 8 stops working and the ventilation component 9 starts running. The ventilation component 9 discharges the harmful substances in the spray chamber 11. After the temperature in the spray chamber 11 returns to room temperature, the electric push rod 44 contracts its output shaft, so that the connecting part 45 moves downward with the clamping component 5 and the components thereon. During this process, the connecting part 45 rotates one hundred and eighty degrees in the opposite direction with the cooperation of the lifting bracket 41. After the components are turned back, the electric push rod 44 stops working, the clamping component 5 releases the clamped components, and then the cabinet door is opened, the components on the stage 2 are taken out, and the next component to be sprayed is placed, and the above steps are repeated to continue production.

[0021] The difference from the above-mentioned embodiment lies in that mounting grooves 21 are provided on both sides of the upper end of the loading platform 2, sliders 22 are fixedly installed on both sides of the lower end of the loading platform 2, a driving groove 23 is also provided on the lower end of the loading platform 2, the driving groove 23 is located between the sliders 22 on both sides, baffles 231 are fixedly connected to both ends of the driving groove 23, and a driving rack 24 is fixedly connected in the driving groove 23.

[0023] When the electric push rod 44 is in the retracted state, the clamping cylinder 51 rests on the support block 42, and the reversing gear 46 is located below the reversing rack 43 and does not mesh with the reversing rack 43. When the electric push rod 44 extends its output shaft, the electric push rod 44 pushes the connecting member 45 and the clamping assembly 5 installed on the connecting member 45 upward through the mounting seat 441, so that the reversing gear 46 moves toward the reversing rack 43 and meshes with the reversing rack 43. After the reversing rack 43 meshes with the reversing gear 46, as the connecting member 45 continues to move upward, the reversing gear 46 moves upward toward the reversing rack 43 and meshes with the reversing rack 43. The reversing rack 43 drives the reversing gear 46 to rotate one hundred and eighty degrees in the forward direction, thereby turning over the component clamped by the clamping assembly 5. After the turning over is completed, the electric push rod 44 stops working. When the component cools to room temperature, the electric push rod 44 contracts its output shaft again, thereby pulling the connecting member 45 and the clamping assembly 5 installed on the connecting member 45 to move downward. As the connecting member 45 descends, the reversing rack 43 drives the reversing gear 46 to rotate one hundred and eighty degrees in the reverse direction, thereby turning over the component again and causing the component to fall back onto the worktable 2.

[0024] The difference from the above embodiment is that the clamping assembly 5 includes a clamping cylinder 51 and a clamping claw 52, ​​one side of the clamping cylinder 51 is fixedly connected to the other side of the connecting member 45, and the clamping claw 52 is matched on the output end of the clamping cylinder 51, and the clamping cylinder 51 can drive the clamping claw 52 to open and close.

[0025] Among them, at the beginning, the clamping cylinder 51 opens the clamping claw 52. When placing the component, the two ends of the component are placed in the opened clamping claw 52. Then the clamping cylinder 51 drives the clamping claw 52 to close, so as to clamp and fix the two ends of the component. After the spraying is completed, the clamping cylinder 51 drives the clamping claw 52 to open again to end the clamping of the component.

[0026] The difference from the above embodiment is that the spray assembly 6 also includes a feed pipe 611 and a storage box 62, one end of the feed pipe 611 is fixedly connected to the atomizing nozzle 61, the storage box 62 is slidably installed on the spray cabinet 1, and is located at the upper end of the spray room 11, the other end of the feed pipe 611 is fixedly connected to the storage box 62, and the storage box 62 transports the paint into the atomizing nozzle 61 through the feed pipe 611.

[0027] When in use, the paint needs to be filled into the storage box 62. When spraying parts, the paint in the storage box 62 is transported to the atomizing nozzle 61 through the delivery pipe 611. The atomizing nozzle 61 atomizes the paint and sprays it evenly on the parts.

[0028] The difference from the above embodiment is that the driving assembly 7 includes a driving motor 71, which is fixedly mounted on the outside of the spray cabinet 1, and the output shaft of the driving motor 71 passes through the spray chamber 11. A driving screw 72 is coaxially fixedly connected to the output shaft of the driving motor 71, and the driving screw 72 is rotatably mounted in the spray chamber 11 and is located at the upper end of the stage 2. A guide rod 73 is also fixedly mounted in the spray chamber 11, and the guide rod 73 is located on one side of the driving screw 72 and is located on the same horizontal plane as the driving screw 72.

[0029] When spraying parts, the driving motor 71 drives the driving screw 72 to rotate in the same direction by rotating in the forward direction or the reverse direction, thereby driving the atomizing nozzle 61 to reciprocate.

[0030] The difference from the above embodiment is that the driving assembly 7 also includes a driving block 74 and a telescopic cylinder 75, one side of the driving block 74 is threadedly assembled on the driving screw 72, and the other side of the driving block 74 is slidably assembled on the guide rod 73, and the telescopic cylinder 75 is fixedly installed on the upper side of the driving block 74, and the output shaft of the telescopic cylinder 75 passes through the driving block 74 toward the worktable 2, and a fixed rod 76 is fixedly connected to the output shaft of the telescopic cylinder 75, and the atomizing nozzle 61 is fixedly installed on the fixed rod 76.

[0031] Among them, when the driving screw 72 rotates forward, the driving block 74 moves from one side of the worktable 2 to the other side, and when the driving screw 72 rotates reversely, the driving block 74 returns from the other side of the worktable 2 to the original side. During the spraying process, the height between the atomizing nozzle 61 and the component can be changed by the telescopic cylinder 75. When it is necessary to lower the height between the atomizing nozzle 61 and the component, the telescopic cylinder 75 extends its output shaft, thereby pushing the fixing rod 76 to move downward, so that the atomizing nozzle 61 on the fixing rod 76 approaches the component.

[0032] The difference from the above embodiment lies in that a slide rail 111 corresponding to the slider 22 is fixedly installed at the bottom of the spray chamber 11, the slider 22 is slidably installed on the slide rail 111, a motor slot 112 is provided at the bottom of the spray chamber 11, the motor slot 112 is located between the slide rails 111, a motor 3 is fixedly installed in the motor slot 112, a driving gear 31 is coaxially fixedly connected to the output shaft of the motor 3, the driving gear 31 is meshed with the driving rack 24, an air supply port 113 is also provided on one side of the bottom of the spray chamber 11, a hot air blower 8 is fixedly installed at the bottom of the spray chamber 11, and the hot air blower 8 is connected to the air supply port 113 through an air supply duct 81.

[0033] Among them, when the motor 3 rotates the driving gear 31 in the forward direction, the driving gear 31 drives the stage 2 to move toward the cabinet door by driving the rack 24. When the motor 3 rotates the driving gear 31 in the reverse direction, the driving gear 31 drives the stage 2 to move away from the cabinet door by driving the rack 24. When the parts need to be dried, the hot air blower 8 generates hot air and transports it to the air supply port 113 through the air supply duct 81. The hot air enters the spray chamber 11 through the air supply port 113 to heat the air in the spray chamber 11.

[0034] The difference from the above-mentioned embodiment is that the exhaust assembly includes a ventilation fan 91 and a treatment box 93.

[0035] Among them, after the drying is completed, the ventilation fan 91 is started, and the gas in the spray chamber 11 is discharged into the processing box 93 through the exhaust duct 92. The activated carbon in the processing box 93 absorbs the harmful substances contained in the gas, preventing the operator from inhaling harmful substances when opening the cabinet door to take out the components, causing damage to his health, thereby ensuring that the operator can work safely.

[0036] The difference from the above-mentioned embodiment is that a spraying method for automobile modification uses an atomizing spraying device.

[0037] Working principle: When in use, first start the motor 3 to rotate forward, and the driving gear 31 drives the stage 2 to move toward the door of the spray cabinet 1 by driving the rack 24, so that the operator can place the parts conveniently. When the stage 2 moves to the door of the spray cabinet 1, turn off the motor 3, stop the movement of the stage 2, and open the door of the spray cabinet 1 to place the parts to be sprayed on the stage 2. In the beginning, the clamping cylinder 51 opens the clamping claw 52. When placing the parts, the two ends of the parts are placed in the opened clamping claw 52. Then the clamping cylinder 51 drives the clamping claw 52 to close, so as to clamp and fix the two ends of the parts. At this time, the output shaft of the electric push rod 44 is in a retracted state, and its connecting piece 45 is located at the lower end of the lifting bracket 41. The clamping cylinder 51 is placed on the support block 42. The reversing gear 46 is located below the reversing rack 43 and is not engaged with the reversing rack 43. The atomizing nozzle 61 is located The clamping assembly 5 clamps the component to one side above the stage 2 and aligns it with the inward end of the component. After the clamping assembly 5 clamps the component, the cabinet door is closed and the spraying work begins. The atomizing nozzle 61 sprays the paint onto the upper surface of the component. At the same time, the motor 3 rotates the driving gear 31 in the reverse direction, and the stage 2 drives the component to move into the spraying chamber 11, so that the outward end of the component moves under the atomizing nozzle 61. During the movement of the stage 2, the driving motor 71 drives the screw 72 to rotate forward, and the driving block 74 drives the atomizing nozzle 61 to move toward the other side of the stage 2. After the atomizing nozzle 61 moves to the other side of the stage 2, the driving motor 71 drives the screw 72 to rotate in the reverse direction, and the driving block 74 drives the atomizing nozzle 61 back to the original side. When the stage 2 delivers the outward end of the component to the atomizing nozzle 61, the driving assembly 7 has driven the atomizing nozzle 61 to reciprocate multiple times, thereby evenly coating the upper surface of the component. Subsequently, the electric push rod 44 extends its output shaft, and the electric push rod 44 pushes the connecting member 45 and the clamping assembly 5 installed on the connecting member 45 upward through the mounting seat 441, so that the reversing gear 46 moves toward the reversing rack 43 and meshes with the reversing rack 43. After the reversing rack 43 meshes with the reversing gear 46, as the connecting member 45 continues to move upward, the reversing rack 43 drives the reversing gear 46 to rotate 180 degrees in the positive direction, thereby turning over the component clamped by the clamping assembly 5 so that the lower surface of the component faces the atomizing nozzle 61. After the component is turned over, the electric push rod 44 The push rod 44 stops working. At this time, the connecting piece 45 is located at the upper end of the lifting bracket 41. At the same time, the stage 2 drives the component to move toward the cabinet door. During the movement of the component, the driving assembly 7 drives the atomizing nozzle 61 to reciprocate and spray the lower surface of the component. When the stage 2 moves the component back to the cabinet door, the atomizing nozzle 61 completes the spraying of the component. At this time, the hot air blower 8 starts to deliver hot air to the spraying room 11 to heat the air in the spraying room 11, thereby drying the component that has just been sprayed. In this process, the electric push rod 44 is lifted The components can be fully contacted with the hot air in the spray chamber 11, thereby accelerating the drying speed. After the components are dried, the hot air blower 8 stops working, and the ventilation fan 91 of the ventilation component 9 starts, and the gas in the spray chamber 11 is discharged into the treatment box 93 through the exhaust pipe 92. The activated carbon in the treatment box 93 absorbs the harmful substances contained in the gas, preventing the operator from inhaling harmful substances when opening the cabinet door to take out the components, causing damage to the health, thereby ensuring that the operator can work safely. After the temperature in the spray chamber 11 returns to room temperature , the electric push rod 44 contracts its output shaft, thereby pulling the connecting piece 45 and the clamping assembly 5 installed on the connecting piece 45 to move downward. As the connecting piece 45 descends, the reversing rack 43 drives the reversing gear 46 to rotate 180 degrees in the opposite direction, thereby turning the component over again and making the component fall back onto the stage 2. After the component is turned back, the electric push rod 44 stops working, the clamping assembly 5 releases the clamped component, and then opens the cabinet door, takes out the component on the stage 2, and puts in the next component to be sprayed, and repeats the above steps to continue production.
