Description

Technical Field

[0001] The present invention relates to the technical field of fluorocarbon aluminum veneers, and particularly to a spraying production line for fluorocarbon aluminum veneers and its spraying process. Background Art

[0002] Fluorocarbon aluminum veneer is a high-performance metal material commonly used in building decoration. For example, in a fluorocarbon aluminum veneer curtain wall, there are multiple box-shaped aluminum veneers combined. Moreover, the fluorocarbon aluminum veneer combines the light weight and high strength of aluminum with the excellent weather resistance and corrosion resistance of the fluorocarbon coating. In order to ensure the weather resistance and corrosion resistance of the aluminum veneer curtain wall, it is necessary to perform coating spraying treatment on it. The existing spraying production line transports the aluminum veneer to the spraying station by a hanging conveying structure. The bottom of the hanging aluminum veneer will be inclined due to the position of the upper hook. The inclination of the aluminum veneer will cause the distances between the top and bottom of the workpiece and the spray gun to be different. Different distances will result in uneven coating thickness sprayed by the spray gun onto the aluminum veneer during spraying. Moreover, the hanging aluminum veneer will swing to a certain extent during the moving transportation process, causing the distance between the aluminum veneer and the spray gun to change, further affecting the uniformity of the coating. In addition, during the spraying process, the impact of the coating on the aluminum veneer will also cause the aluminum veneer to swing, affecting the uniformity of the coating and the performance of the aluminum veneer.

[0009] Further, the workpiece control mechanism further includes a rotating shaft rotatably connected inside the U-shaped slider. There is a strong frictional force between the rotating shaft and the U-shaped slider. A first bevel gear is fixed to one end of the rotating shaft. A second bevel gear is meshed with one side of the first bevel gear. A connecting shaft is fixed to one end of the second bevel gear. A first one-way gear and a third one-way gear are installed at one end of the connecting shaft.

The bottom end of the spring is fixed to the moving plate, and the top end of the spring is fixed to the movable plate. Push rod motors are fixed to both sides of the movable plate.

[0011] Further, the controller is fixed on the outer wall of the spraying box, and the controller is electrically connected to the laser distance detector, the push rod motor, the first motor, the heating lamp, the suspension conveyor track, the second motor, and the spray gun group respectively.

[0012] The fluorocarbon aluminum single-plate spraying process, which is applicable to the above-mentioned fluorocarbon aluminum single-plate spraying production line, includes the following steps: Step 1: The controller starts the suspension conveyor track to drive the slider to drive the hook and the workpiece to enter the interior of the spraying box from the first feeding port. The laser distance detector starts to emit laser. After the workpiece moves to one side of the laser distance detector, the laser distance detector transmits a signal to the controller, and the controller stops the operation of the suspension conveyor track; Step 2: Start the second motor to drive the screw to rotate, so that the U-shaped slider drives the rotating shaft, bevel gear 1, bevel gear 2, one-way gear 1, mounting plate, mounting block, reciprocating screw 2, one-way gear 2, guide rod 2, moving plate, guide rod 3, spring, movable plate, push rod motor, and electromagnet to move away from the first feeding port, and move to the rear of the workpiece. When moving, the one-way gear 1 meshes with the rack 1, and the moving direction of the one-way gear 1 satisfies the steering for driving the connecting shaft to rotate by the one-way gear 1. The rotation of the connecting shaft drives the bevel gear 2 and the bevel gear 1 to rotate. The bevel gear 1 drives the rotating shaft to rotate clockwise. The rotating shaft drives the mounting block to rotate 90 degrees. Then the one-way gear 1 disengages from the rack 1. The rotation of the mounting block will drive the reciprocating screw 2, one-way gear 2, guide rod 2, moving plate, guide rod 3, spring, movable plate, push rod motor, and electromagnet to rotate, and rotate the reciprocating screw 2, one-way gear 2, guide rod 2, moving plate, guide rod 3, spring, movable plate, push rod motor, and electromagnet from the horizontal state to the vertical state, so that the electromagnet is located on the back of the workpiece, and then turn off the second motor; Step 3: A plurality of laser distance detectors obtain the distances of multiple points on the workpiece from top to bottom, and then transmit them to the controller. If it is detected that the distance above the workpiece is less than the distance below the workpiece, it means that the bottom of the workpiece is tilted backward. On the contrary, the bottom of the workpiece is tilted forward. When tilted forward, the controller starts the push rod motor to push the electromagnet close to the inner wall of the back of the workpiece tilted forward, and starts the electromagnet to suck the workpiece through the ball. The push rod motor pulls the electromagnet to pull the bottom of the workpiece backward. During the pulling process, the laser distance detector always obtains the distance. When the distances above and below the workpiece are the same, the workpiece is in a vertical state. When the vertical workpiece is reciprocally sprayed up and down by the spray gun group, the distance between the two always remains the same; Step 4: Then start the suspension conveyor rail and Motor 2 to run. The moving speed of the U-shaped slider is the same as that of the workpiece, and the two move synchronously. During the movement, the one-way gear 2 meshes with and rotates along Rack 3. At this time, the moving direction of the one-way gear 2 during rotation meets the steering for driving the reciprocating screw 2 to rotate, causing the moving plate to pull the guide rod 3, spring, movable plate, push rod motor, electromagnet, and ball to move downward. The ball reduces the friction between the electromagnet and the workpiece when the electromagnet moves downward. When the bottom of the electromagnet contacts and is limited by the inner wall of the bottom of the workpiece and can no longer move downward, the moving plate and the movable plate move away from each other, stretching the spring. After the moving plate moves to the end of the screw thread at the bottom of the reciprocating screw 2, the one-way gear 2 disengages from Rack 3, and the electromagnet generates a downward pulling force on the inner wall of the bottom of the workpiece; Step 5: Continue to move synchronously. When the workpiece moves in front of the spray gun group, the spray gun group turns on the spray gun for spraying the first layer of coating. The spray gun atomizes and sprays the coating on the surface of the workpiece. At the same time, the controller controls Motor 1 to drive the reciprocating screw 1 to rotate, causing the spray gun group to move up and down. After the workpiece moves a certain distance, the spraying of the first layer of coating on the entire workpiece is completed, and the spray gun group is turned off; Step 6: Continue to move synchronously. The one-way gear 2 meshes with Rack 4, causing the moving plate and the electromagnet to move upward. Before moving upward, turn off the electromagnet. At this time, the electromagnet is disconnected from the workpiece; Step 7: Continue to move synchronously. The one-way gear 3 meshes with Rack 2. Therefore, the moving direction of the one-way gear 3 at this time cannot drive the connecting shaft to rotate. When the one-way gear 3 disengages from Rack 2, start Motor 2 to reverse, causing the U-shaped slider to move back. When the one-way gear 3 meshes with Rack 2 again, the moving direction of moving back meets the steering for the one-way gear 3 to drive the connecting shaft to rotate. The connecting shaft drives the rotating shaft to rotate counterclockwise through the bevel gear 2 and bevel gear 1, causing the mounting block to drive the reciprocating screw 2, one-way gear 2, guide rod 2, moving plate, guide rod 3, spring, movable plate, push rod motor, and electromagnet to reset from the vertical state to the horizontal state. Then continue to move back. The one-way gear 2 meshes with Rack 4 but does not meet the steering for driving the reciprocating screw 2. Continuing to move, the one-way gear 1 meshes with Rack 1 but does not meet the steering for driving the connecting shaft to rotate. Then the one-way gear 2 meshes with Rack 3 but does not meet the steering for driving the reciprocating screw 2. Then, after the U-shaped slider moves to the end of the screw thread, it stops moving and waits for the next workpiece to move over; Step 8: The workpiece moves through the second feeding port and enters the interior of the curing chamber. The heating lamp in the curing chamber cures the coating. The cured workpiece is moved back to the interior of the spraying chamber by the suspension conveyor rail, and then the second layer of coating is sprayed according to the above steps. After spraying, the workpiece is cured again, and the cured workpiece is conveyed away from the curing chamber by the suspension conveyor rail.

[0013] Compared with the existing technology, the beneficial effects of the present invention are: In the present invention, by installing a workpiece control mechanism, the distance between the spray gun group and different positions of the workpiece remains consistent during the up-and-down reciprocating spraying, avoiding the situation of uneven spraying thickness caused by different distances between different positions of the workpiece and the spray gun group. Moreover, a downward pulling force is generated on the workpiece, making the workpiece more stable and not prone to shaking, and avoiding the impact and shaking of the fluid sprayed by the spray gun group on the workpiece, which may cause a change in the distance between the workpiece and the spray gun group, thereby affecting the uniformity of the spraying thickness.

[0034] Example 2: Refer to Figures 1 - 8 : Based on Example 1, this example provides a fluorocarbon aluminum veneer spraying process, which is applicable to the above-mentioned fluorocarbon aluminum veneer spraying production line, and includes the following steps: Step 1: The controller 5 starts the suspension conveyor rail 31 to drive the slider 32 to drive the hook 33 and the workpiece 34 to enter the interior of the spraying box 11 from the first feeding port 12. The laser distance detector 424 starts to emit laser. After the workpiece 34 moves to one side of the laser distance detector 424, the laser distance detector 424 transmits a signal to the controller 5, and the controller 5 stops the operation of the suspension conveyor rail 31; Step 2: Start the second motor 43 to drive the screw 42 to rotate, so that the U-shaped slider 44 drives the rotating shaft 45, bevel gear 46, bevel gear 47, one-way gear 48, mounting plate 49, mounting block 412, reciprocating screw 413, one-way gear 414, guide rod 415, moving plate 416, guide rod 419, spring 421, movable plate 420, push rod motor 422 and electromagnet 423 to move away from the first feeding port 12 and move to the rear of the workpiece 34. When moving, the one-way gear 48 meshes with the first rack 410, and the moving direction of the one-way gear 48 satisfies the steering direction of driving the connecting shaft to rotate by the one-way gear 48. The rotation of the connecting shaft drives the bevel gear 47 and the bevel gear 46 to rotate. The bevel gear 46 drives the rotating shaft 45 to rotate clockwise. The rotating shaft 45 drives the mounting block 412 to rotate 90 degrees. Then the one-way gear 48 disengages from the first rack 410. The rotation of the mounting block 412 drives the reciprocating screw 413, one-way gear 414, guide rod 415, moving plate 416, guide rod 419, spring 421, movable plate 420, push rod motor 422 and electromagnet 423 to rotate, and rotates the reciprocating screw 413, one-way gear 414, guide rod 415, moving plate 416, guide rod 419, spring 421, movable plate 420, push rod motor 422 and electromagnet 423 from the horizontal state to the vertical state, so that the electromagnet 423 is located on the back of the workpiece 34, and then turn off the second motor 43; Step 3: Multiple laser distance detectors 424 obtain the distances of multiple points from top to bottom of the workpiece 34, and then transmit them to the controller 5. If it is detected that the distance above the workpiece is smaller than the distance below the workpiece 34, it means that the bottom of the workpiece 34 is tilted backwards, otherwise the bottom of the workpiece 34 is tilted forwards. When it tilts forwards, the controller 5 starts the push rod motor 422 to push the electromagnet 423 close to the inner wall of the back side of the workpiece 34 tilted forwards, and starts the electromagnet 423 to suck the workpiece 34 through the ball 425. The push rod motor 422 pulls the electromagnet 423 to pull the bottom of the workpiece 34 backwards. During the pulling process, the laser distance detector 424 always obtains the distance. When the distances above and below the workpiece 34 are the same, the workpiece 34 is in a vertical state. When the workpiece 34 in the vertical state is sprayed up and down by the spray gun group 17, the distance between the two is always consistent, so as to avoid the situation where the distances between different positions of the workpiece and the spray gun group 17 are different, resulting in uneven spraying thickness. Step 4: Then start the suspension conveyor rail 31 and the motor 2 43 to run. The moving speed of the U-shaped slider 44 is the same as the moving speed of the workpiece 34. The two move synchronously. During the movement, the one-way gear 2 414 meshes and rotates with the rack 3 417. At this time, the moving direction of the one-way gear 2 414 meets the direction of driving the reciprocating screw 2 413 to rotate during rotation, so that the moving plate 416 pulls the guide rod 3 419, the spring 421, the movable plate 420, the push rod motor 422, the electromagnet 423 and the ball 425 to move downward. The ball 425 reduces the friction between the electromagnet 423 and the workpiece 34 when it moves downward. After the bottom of the magnet 423 contacts the bottom inner wall of the workpiece 34 and reaches a limit position, it cannot move downward any further. The movable plate 416 and the movable plate 420 move away from each other, causing the spring 421 to stretch. After the movable plate 416 moves to the bottom thread tail of the reciprocating screw rod 413, the one-way gear 414 and the rack 417 are disengaged. The electromagnet 423 generates a downward pulling force on the bottom inner wall of the workpiece 34. The pulling force makes the workpiece 34 more stable and less likely to shake, thereby preventing the fluid sprayed from the spray gun assembly 17 from causing impact and shaking on the workpiece 34, causing the distance between the workpiece 34 and the spray gun assembly 17 to change, thereby affecting the uniformity of the spraying thickness. Step 5: Continue to move synchronously, the workpiece 34 moves to the front of the spray gun group 17, the spray gun group 17 starts the spray gun for spraying the first layer of paint, and the spray gun sprays the paint on the surface of the workpiece 34 in an atomized form. At the same time, the controller 5 controls the motor 13 to drive the reciprocating screw 14 to rotate to move the spray gun group 17 up and down. After the workpiece 34 moves a certain distance, the first layer of paint spraying of the entire workpiece 34 is completed, and the spray gun group 17 is closed; Step 6: Continue to move synchronously, the one-way gear 2 414 meshes with the rack 4 418, so that the moving plate 416 and the electromagnet 423 move upward, and the electromagnet 423 is turned off before moving upward, at which time the electromagnet 423 and the workpiece 34 are disconnected; Step Seven: Continue the synchronous movement. The one-way gear three 426 meshes with the rack two 411. Therefore, the moving direction of the one-way gear three 426 at this time cannot drive the connecting shaft to rotate. After the one-way gear three 426 disengages from the rack two 411, start the motor two 43 to reverse, so that the U-shaped slider 44 moves back, making the one-way gear three 426 mesh with the rack two 411 again. The moving-back direction meets the steering for the one-way gear three 426 to drive the connecting shaft to rotate. The connecting shaft drives the rotating shaft 45 to rotate counterclockwise through the bevel gear two 47 and the bevel gear one 46, so that the mounting block 412 drives the reciprocating screw two 413, the one-way gear two 414, the guide rod two 415, the moving plate 416, the guide rod three 419, the spring 421, the movable plate 420, the push rod motor 422 and the electromagnet 423 to reset from the vertical state to the horizontal state, and then continue to move back. The one-way gear two 414 meshes with the rack four 418 but does not meet the steering for driving the reciprocating screw two 413. Continuing to move, the one-way gear one 48 meshes with the rack one 410 but does not meet the steering for driving the connecting shaft to rotate. Then the one-way gear two 414 meshes with the rack three 417 but does not meet the steering for driving the reciprocating screw two 413. Then the U-shaped slider 44 moves to the thread end of the screw 42 and stops moving, waiting for the next workpiece 34 to move over; Step Eight: The workpiece 34 moves through the feeding port two 23 into the interior of the curing box 21. The heating lamp 22 in the curing box 21 cures the coating. The cured workpiece 34 is moved back to the interior of the spraying box 11 by the hanging conveyor rail 31, and then the second layer of coating is sprayed according to the above steps. The sprayed workpiece 34 is cured again, and the cured workpiece 34 is conveyed away from the curing box 21 by the hanging conveyor rail 31.

9. Fluorocarbon aluminum single panel spraying process, which is applicable to the fluorocarbon aluminum single panel spraying production line described in claim 8, characterized in that, Including the following steps: Step 1: The controller (5) starts the suspension conveyor rail (31) to drive the slider (32) to drive the hook (33) and the workpiece (34) to enter the interior of the spraying box (11) from the first feeding port (12). The laser distance detector (424) starts to emit laser. After the workpiece (34) moves to one side of the laser distance detector (424), the laser distance detector (424) transmits a signal to the controller (5), and the controller (5) stops the operation of the suspension conveyor rail (31). Step 2: Start the second motor (43) to drive the screw (42) to rotate, so that the U-shaped slider (44) drives the rotating shaft (45), the first bevel gear (46), the second bevel gear (47), the first one-way gear (48), the mounting plate (49), the mounting block (412), the reciprocating screw two (413), the second one-way gear (414), the second guide rod (415), the moving plate (416), the third guide rod (419), the spring (421), the movable plate (420), the push rod motor (422) and the electromagnet (423) to move away from the first feeding port (12) and move to the rear of the workpiece (34). When moving, the first one-way gear (48) meshes with the first rack (410), and the moving direction of the first one-way gear (48) satisfies the steering of driving the connecting shaft to rotate by the first one-way gear (48). The rotation of the connecting shaft drives the second bevel gear (47) and the first bevel gear (46) to rotate. The first bevel gear (46) drives the rotating shaft (45) to rotate clockwise. The rotating shaft (45) drives the mounting block (412) to rotate 90 degrees. Then the first one-way gear (48) disengages from the first rack (410). The rotation of the mounting block (412) drives the reciprocating screw two (413), the second one-way gear (414), the second guide rod (415), the moving plate (416), the third guide rod (419), the spring (421), the movable plate (420), the push rod motor (422) and the electromagnet (423) to rotate, and rotates the reciprocating screw two (413), the second one-way gear (414), the second guide rod (415), the moving plate (416), the third guide rod (419), the spring (421), the movable plate (420), the push rod motor (422) and the electromagnet (423) from the horizontal state to the vertical state, so that the electromagnet (423) is located on the back of the workpiece (34), and then turn off the second motor (43). Step 3: Multiple laser distance detectors (424) obtain the distances of multiple points on the workpiece (34) from top to bottom and then transmit them to the controller (5). If the distance above the workpiece is detected to be less than that below the workpiece (34), it indicates that the bottom of the workpiece (34) is tilted backward. Conversely, if the distance below the workpiece (34) is less than that above, it means the bottom of the workpiece (34) is tilted forward. When tilted forward, the controller (5) activates the push rod motor (422) to push the electromagnet (423) close to the inner wall of the back of the forward-tilted workpiece (34), activates the electromagnet (423) to suck the workpiece (34) through the ball (425), and the push rod motor (422) pulls the electromagnet (423) to pull the bottom of the workpiece (34) backward. During the pulling process, the laser distance detector (424) always obtains the distance. When the distances above and below the workpiece (34) are the same, the workpiece (34) is in a vertical state. When the vertical workpiece (34) reciprocates up and down under the spray gun group (17), the distance between them always remains the same, avoiding the situation of uneven spraying thickness caused by different distances between different positions of the workpiece and the spray gun group (17). Step 4: Then start the suspension conveyor rail (31) and the second motor (43) to run. The moving speed of the U-shaped slider (44) is the same as that of the workpiece (34), and the two move synchronously. During the movement, the one-way gear two (414) meshes with the rack three (417) and rotates. At this time, the moving direction of the one-way gear two (414) during rotation satisfies the steering that drives the reciprocating screw two (413) to rotate, so that the moving plate (416) pulls the guide rod three (419), the spring (421), the movable plate (420), the push rod motor (422), the electromagnet (423), and the ball (425) downward. The ball (425) reduces the friction between the electromagnet (423) and the workpiece (34) when the electromagnet (423) moves downward. When the bottom of the electromagnet (423) contacts and limits the inner wall of the bottom of the workpiece (34) and cannot move downward anymore, the moving plate (416) and the movable plate (420) move away from each other, stretching the spring (421). After the moving plate (416) moves to the end of the screw thread at the bottom of the reciprocating screw two (413), the one-way gear two (414) disengages from the rack three (417), and the electromagnet (423) generates a downward pulling force on the inner wall of the bottom of the workpiece (34). Step 5: Continue to move synchronously. The workpiece (34) moves in front of the spray gun group (17). The spray gun group (17) turns on the spray gun for spraying the first layer of coating. The spray gun atomizes and sprays the coating on the surface of the workpiece (34). At the same time, the controller (5) controls the first motor (13) to drive the reciprocating screw one (14) to rotate, causing the spray gun group (17) to move up and down. After the workpiece (34) moves a certain distance, the spraying of the first layer of coating on the entire workpiece (34) is completed, and the spray gun group (17) is turned off. Step 6: Continue to move synchronously. The one-way gear two (414) meshes with the rack four (418), causing the moving plate (416) and the electromagnet (423) to move upward. Before moving upward, turn off the electromagnet (423). At this time, the electromagnet (423) is disconnected from the workpiece (34). Step Seven: Continue synchronous movement. The one-way gear three (426) meshes with the rack two (411), so the moving direction of the one-way gear three (426) at this time cannot drive the connecting shaft to rotate. After the one-way gear three (426) disengages from the rack two (411), start the motor two (43) to reverse, so that the U-shaped slider (44) moves back, making the one-way gear three (426) mesh with the rack two (411) again. The moving-back direction meets the steering for the one-way gear three (426) to drive the connecting shaft to rotate. The connecting shaft drives the rotating shaft (45) to rotate counterclockwise through the bevel gear two (47) and the bevel gear one (46), so that the mounting block (412) drives the reciprocating screw two (413), the one-way gear two (414), the guide rod two (415), the moving plate (416), the guide rod three (419), the spring (421), the movable plate (420), the push rod motor (422) and the electromagnet (423) to reset from the vertical state to the horizontal state, and then continue to move back. The one-way gear two (414) meshes with the rack four (418) but does not meet the steering to drive the reciprocating screw two (413). Continuing to move, the one-way gear one (48) meshes with the rack one (410) but does not meet the steering to drive the connecting shaft to rotate. Then the one-way gear two (414) meshes with the rack three (417) but does not meet the steering to drive the reciprocating screw two (413). Then the U-shaped slider (44) moves to the thread end of the screw (42) and stops moving, waiting for the next workpiece (34) to move over; Step Eight: The workpiece (34) moves through the feed inlet two (23) and enters the interior of the curing box (21). The heating lamp (22) in the curing box (21) cures the coating. The cured workpiece (34) is moved back to the interior of the spraying box (11) by the hanging conveyor rail (31), and then the second layer of coating is sprayed according to the above steps. The sprayed workpiece (34) is cured again. The cured workpiece (34) is conveyed away from the curing box (21) by the hanging conveyor rail (31).
