Description

Technical Field

[0001] This application belongs to the field of spraying equipment technology, and particularly relates to an aluminum profile spraying device and its spraying method. Background Technology

[0002] In the processing of aluminum profiles, a spraying process is required, and powder coating is one of them. Powder coating uses powder spraying equipment to spray powder coating onto the surface of the aluminum profile. Under the action of electrostatics, the powder will be evenly adsorbed onto the surface of the workpiece to form a powdery coating. The powdery coating is then baked at high temperature to level and cure, becoming a final coating with different effects. The coating effect of powder coating is superior to that of painting in terms of mechanical strength, adhesion, corrosion resistance, and aging resistance, and the cost is also lower than that of painting with the same effect.

[0023] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0024] Example 1: like Figure 1 , Figure 2 As shown in the figure, this application provides an aluminum profile spraying device, including: The spraying box 100 is equipped with a box door 110; A spraying system 200 is installed in a spraying box 100. The spraying system 200 includes a spray nozzle 210 and is used to spray powder coating. A clamping mechanism 300 is installed in a spray box 100. The clamping mechanism 300 includes a clamping seat 310, a first chuck seat 320, and a second chuck seat 330. Both the first chuck seat 320 and the second chuck seat 330 are provided with clamping parts 301. The first chuck seat 320 and the second chuck seat 330 cooperate with each other to form a set. The clamping mechanism 300 is provided with two sets of first chuck seats 320 and second chuck seats 330. The first chuck seat 320 and the second chuck seat 330 are movably installed on the clamping seat 310. Rotating mechanism 400 is used to drive the clamping mechanism 300 to rotate.

[0025] The aluminum profile workpiece requiring coating is placed in the coating box 100, with the box door 110 facilitating its entry and exit. Coating is sprayed from the nozzle 210 in the coating system 200 onto the aluminum profile workpiece. The nozzle 210 is connected to a coating storage device and is mounted on a moving component such as a robotic arm or guide rail, allowing it to move along the axis of the aluminum profile workpiece for coating. The aluminum profile workpiece is clamped by the clamping mechanism 300. When the aluminum profile workpiece is plate-shaped, it is externally clamped by the clamping mechanism 300, with the first chuck 320 and the second chuck 330 in a closed state (clamping state). When the aluminum profile workpiece is tubular, it is clamped by the clamping mechanism 300... The aluminum profile workpiece is internally clamped. At this time, the first chuck 320 and the second chuck 330 are in the open state, which is the clamping state. The clamping mechanism 300 improves the applicability of clamping the aluminum profile workpiece. The clamping part 301 is placed at the end of the first chuck 320 and the second chuck 330 respectively. The clamping part 301 is used to abut against the aluminum profile workpiece. The first chuck 320 and the second chuck 330 are movably mounted on the clamping seat 310. The clamping seat 310 is installed and connected to the rotating mechanism 400. The rotating mechanism 400 is used to control the rotation of the clamping seat 310 to realize the workpiece flipping control. The spray box 100 has clamping mechanisms 300 at both ends for clamping the two ends of the aluminum profile.

[0026] Example 2: like Figures 1-6 As shown, this application embodiment provides an aluminum profile spraying device, which, in addition to the above-mentioned technical features, further includes the following: The movable seat 340 is movably connected to the clamping seat 310, and the first chuck seat 320 and the second chuck seat 330 are movably mounted on the movable seat 340; The control mechanism 350 is connected to the first chuck seat 320 and the second chuck seat 330, and the control mechanism 350 is used to control the movement of the first chuck seat 320 and the second chuck seat 330.

[0027] The movable seat 340 is movably mounted on the clamping seat 310. Each movable seat 340 is equipped with a first chuck seat 320 and a second chuck seat 330. The movable seat 340 is movably mounted on the clamping seat 310. The position of the movable seat 340 is adjusted by connecting a threaded rod, a nut seat, and a motor. The threaded rod has two threaded portions with opposite thread directions, which can control the two movable seats 340 so that the clamping position of the first chuck seat 320 and the second chuck seat 330 can be adapted to the aluminum profile workpiece, further improving the applicability of the clamping mechanism 300. The control mechanism 350 is connected to the first chuck seat 320 and the second chuck seat 330. The control mechanism 350 is used to control the movement of the first chuck seat 320 and the second chuck seat 330 to achieve the clamping of the aluminum profile workpiece.

[0028] Furthermore, the control mechanism 350 includes: There are two connecting rods 351, each of which is connected to one of the two first chuck seats 320. A scissor bracket 352 has one end connected to two connecting rods 351 respectively, and the other end of the scissor bracket 352 is provided with a first drive cylinder 353; The connecting seat 354 is movably connected to the second chuck seat 330, and the connecting seat 354 is provided with a second drive cylinder 355; The hinge shaft 356 is movably connected to the first chuck seat 320; The second chuck seat 330 is provided with a first sliding groove 331, the connecting seat 354 is provided with a first sliding part 357 adapted to the first sliding groove 331, the second chuck seat 330 is provided with a waist-shaped groove 332 that is slidably hinged to the hinge shaft 356, the first chuck seat 320 is provided with a groove 321, and the second chuck seat 330 is provided with a protrusion 333, the groove 321 and the protrusion 333 corresponding to each other.

[0029] The first chuck seats 320 on the two movable seats 340 correspond to the two connecting rods 351 respectively. The first chuck seats 320 and second chuck seats 330 on the two movable seats 340 are arranged such that one set of first chuck seats 320 is above the second chuck seats 330, and the other set is below the second chuck seats 330. A scissor bracket 352 is connected to the connecting rods 351 and a first drive cylinder 353. The first drive cylinder 353 is a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The first drive cylinder 353 controls the movement of the scissor bracket 352 and the connecting rods 351, thereby controlling the movement of the first chuck seats 320. The connecting rods 351 are movably connected to the first chuck seats 320, allowing the first chuck seats 320 to move with the movable seats 340. A hinge shaft 356 is mounted on the movable seats 340 and is connected to the first chuck seats 320, allowing the first chuck seats 320 to rotate... The axis of the hinge shaft 356 rotates, connecting the second chuck seat 330 and the connecting seat 354. The movement of the connecting seat 354 controls the movement of the hinge shaft 356 in the waist-shaped groove 332. When the connecting seat 354 pulls the second chuck seat 330 to move, causing the groove 321 to engage with the protrusion 333, it controls the first chuck seat 320 and the second chuck seat 330 on the same moving seat 340 to move in the same direction. The first sliding groove 331 engages with the second sliding part 371, ensuring the stability of the connection between the connecting seat 354 and the second chuck seat 330. When the connecting seat 354 moves, it controls the movement of the second chuck seat 330, causing the hinge shaft 356 to move relative to the waist-shaped groove 332, controlling the groove 321 to separate from the protrusion 333. When the first chuck seat 320 is acted upon by the connecting rod 351, it allows the first chuck seat 320 and the second chuck seat 330 on the same moving seat 340 to open.

[0030] Furthermore, the clamping mechanism 300 also includes: A rotating base 360 ​​is movably mounted on a movable base 340, and the first chuck base 320 and the second chuck base 330 are mounted in the rotating base 360; The first movable sleeve 370 is movably sleeved on the rotating seat 360, and the first movable sleeve 370 is provided with a second sliding part 371 extending into the rotating seat 360; The first connector 380 is movably connected between the first movable sleeve 370 and the connecting rod 351; The second movable sleeve 390 is movably connected to the rotating seat 360. The second movable sleeve 390 is provided with a third sliding groove 391. The second drive cylinder 355 is connected to the second movable sleeve 390.

[0031] The first chuck seat 320 is provided with a second sliding groove 322 corresponding to the second sliding part 371, and the connecting seat 354 is provided with a third sliding part 358 corresponding to the third sliding groove 391.

[0032] A rotating base 360 ​​is mounted on a movable base 340. A first chuck 320 and a second chuck 330 are movably mounted in the rotating base 360 ​​via a hinge shaft 356. Rotation of the rotating base 360 ​​allows control of the hinge shaft 356's rotation around the axis of the rotating base 360, thereby adjusting the clamping direction of the first chuck 320 and the second chuck 330. A first movable sleeve 370 is mounted on the rotating base 360, and the first movable sleeve 370 can only move along the axial direction of the rotating base 360. One end of the first connecting member 380 can slide along the axial or circumferential direction of the connecting rod 351. The other end of the second connecting member is connected to the first movable sleeve 380. The first movable sleeve 370 and the second movable sleeve 390 are slidably connected. When the connecting rod 351 moves, the movement is transmitted to the first movable sleeve 370 through the first connecting member 380, causing relative movement between the first movable sleeve 370 and the rotating seat 360. This controls the first sliding part 357 to move in the second sliding groove 322, thereby controlling the rotation of the first chuck seat 320 and the hinge seat. The second movable groove is installed on the rotating seat 360 and can move along the axis of the rotating seat 360. The third sliding groove 391 is located on the inner side of the second movable sleeve 390 in an annular shape. The third sliding part 358 cooperates with the third sliding groove 391. When the rotating seat 360 rotates, the third sliding part 358 moves in the third sliding groove 391. Both the first movable sleeve 370 and the second movable sleeve 390 have a structure that extends into the rotating seat 360. The rotating seat 360 has a slot that facilitates the movement of the first movable sleeve 370 and the second movable sleeve 390.

[0033] The above structure enables clamping of a wider range of aluminum profile workpieces, such as L-shaped aluminum profile workpieces. By adjusting the clamping directions of the first chuck 320 and the second chuck 330 through the rotating seat 360, the two clamping directions are made perpendicular, thus achieving clamping of the aluminum profile workpiece. For similar large-diameter cylindrical aluminum profile workpieces, by controlling the engagement of the recess and groove 321, the two first chucks 320 on the two moving seats 340 move in opposite directions, thereby controlling the clamping of the corresponding aluminum profile workpiece and further improving the applicability of the clamping mechanism 300.

[0034] Furthermore, the clamping mechanism 300 also includes: The locking element 361 is threadedly connected to the movable seat 340 and abuts against the rotating seat 360.

[0035] The locking element 361 is threaded onto the movable seat 340. When the rotating seat 360 and the movable seat 340 are rotated and adjusted, the end of the locking element 361 abuts against the rotating seat 360, thereby achieving relative fixation between the rotating seat 360 and the movable seat 340.

[0038] The base 410 is installed in the spray box 100 via a slide rail and a slider. The clamping seat 310 is installed on the rotating disk 420 via bolts and other fasteners. The gear ring 430 is installed on the rotating disk 420 via bolts and other fasteners. The gear 440 meshes with the gear ring 430. The gear 440 is driven to rotate by the drive motor 450, which controls the rotation of the gear ring 430 and the rotating disk 420, thereby realizing the flipping of the clamped aluminum profile workpiece.

[0039] Furthermore, it also includes: The third drive cylinder 460 is installed inside the spray box 100 and connected to the base 410; Limiting block 470 is installed inside spray box 100 and corresponds to base 410; The lifting platform 500 is placed inside the spraying box 100.

[0040] The third drive cylinder 460 is a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The third drive cylinder 460 is installed between the spray box 100 and the base 410. The third drive cylinder 460 is used to control the movement of the base 410. The limit block 470 is used to limit the movement of the base 410. The lifting platform 500 is controlled by a hydraulic cylinder for lifting. The aluminum profile workpiece is placed on the lifting platform 500 for loading and unloading. Then, it is moved to the aluminum profile workpiece by the clamping mechanism 300 and clamped. Alternatively, the aluminum profile workpiece can be placed on the lifting platform 500 and then released away.

[0041] Example 4: This application also provides a spraying method for an aluminum profile spraying device, the specific steps of which include: S1, Determine the type of aluminum profile to be sprayed, and clamp the aluminum profile internally or externally onto the clamping mechanism 300; S2, the spray nozzle 210 of the spraying system 200 moves and sprays paint onto the aluminum profile workpiece, and the aluminum profile is sprayed towards the side of the spray nozzle 210. S3, the clamping mechanism 300 is rotated by the rotating mechanism 400 to rotate the aluminum profile so that the unpainted side faces the spray head 210 for continued spraying. After the spraying is completed, the aluminum profile is removed from the clamping mechanism 300.

[0042] The clamping mechanism 300 is adjusted to fit the aluminum profile workpiece and is used for clamping different aluminum profile workpieces during the spraying process. This ensures the clamping of various aluminum profile workpiece structures and further improves the applicability of the spraying device.
