[0024] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model is described in further detail below in combination with the drawings and specific embodiments.

[0025] Referring to Figures 1 to 7 The utility model provides a kind of electroplating automobile plastic part spraying treatment device, including processing table 1, processing table 1 is provided with top plate 2, the top of processing table 1 is also provided with collection box 3, two groups of support columns 4 are provided symmetrically in collection box 3, the top of support column 4 is provided with the clamping assembly 5 for clamping automobile plastic part and the rotating drive component for driving the automobile plastic part after clamping, the top of top plate 2 is provided with spraying box 6, one side of spraying box 6 is communicated with connecting corrugated pipe 7, the below of top plate 2 is provided with spray head 8, spray head 8 is connected with connecting corrugated pipe 7, adjusting assembly 9 for adjusting the position of spray head 8 is provided between top plate 2 and spray head 8.

[0026] By placing the automobile plastic part to be sprayed in the clamping assembly 5 on the top of the support column 4, the automobile plastic part is clamped and fixed by the clamping assembly 5, ensuring that the automobile plastic part will not move or fall off during the spraying process. The position of the spray head 8 is adjusted as needed by adjusting the adjusting assembly 9, and the spray head 8 is not affected when moving by the setting of the connecting bellows 7. When the other side of the automobile plastic part needs to be sprayed or the corners and gaps of the automobile plastic part cannot be covered, the driving part is rotated to drive the clamped automobile plastic part to rotate, thereby realizing omnidirectional rotation spraying of the automobile plastic part, greatly improving the spraying efficiency. During the spraying process, the excess or splashed spraying liquid falls into the collection box 3, which facilitates subsequent treatment of the spraying liquid.

[0027] Referring to Figures 4 to 5 As shown, the clamping assembly 5 includes a fixed plate 51; the fixed plate 51 is arranged on the top of the support column 4, and a support plate 52 is movably arranged on the fixed plate 51. The fixed plate 51 is provided with a threaded driving part for driving the support plate 52 to move. One side of the support plate 52 is provided with a first rotating shaft 515, one end of the first rotating shaft 515 is provided with a rectangular frame 53, an activity rod 54 is movably arranged in the rectangular frame 53, one end of the activity rod 54 is provided with a pressing plate 55, the other end of the activity rod 54 is provided with a pull plate 56, and a spring 57 is sleeved outside the activity rod 54. One end of the spring 57 abuts against the pressing plate 55, and the other end of the spring 57 abuts against the inner wall of the rectangular frame 53.

Then pull the pull plate 56, the activity rod 54 is moved by the pull plate 56, and the pressing plate 55 is moved by the movement of the activity rod 54. The pressing plate 55 will extrude the spring 57 sleeved on the activity rod 54 during movement, so that the spring 57 is compressed.

[0029] Referring to Figure 4 As shown, one side of the pressing plate 55 is provided with a limiting sliding block, and the inner wall of the rectangular frame 53 is provided with a limiting sliding groove for the movement of the limiting sliding block.

[0030] When the pressing plate 55 moves under the action of the spring 57, the limiting sliding block slides along the trajectory of the limiting sliding groove. The design of the limiting sliding groove ensures that the pressing plate 55 can only move in the predetermined direction and path, thereby preventing the pressing plate 55 from deviating or misplacing during movement, and improving the stability of the movement of the pressing plate 55.

[0031] Referring to Figure 5 As shown in the figure, the rotating driving component comprises a turbine 58 and a mounting frame 59; one end of the first rotating shaft 515 extends outward through the support plate 52, and the turbine 58 is arranged at the extended end of the first rotating shaft 515; the mounting frame 59 is arranged on one side of the support plate 52, and a worm 510 is arranged in the mounting frame 59; one end of the worm 510 extends outward through the mounting frame 59, and a rotating disc 511 is arranged at the extended end of the worm 510.

[0032] When it is necessary to rotate the clamped automobile plastic part, the worker rotates the rotating disc 511 to drive the worm 510 in the mounting frame 59 to rotate; since the worm 510 is engaged with the turbine 58, the turbine 58 is driven to rotate when the worm 510 rotates; the first rotating shaft 515 is driven to rotate through the rotation of the turbine 58; the rectangular frame 53 is driven to rotate through the first rotating shaft 515; thus, the clamped automobile plastic part is rotated, the automobile plastic part is rotated in all directions, and the spraying efficiency is greatly improved.

[0033] Referring to Figure 4 As shown in the figure, the threaded driving component comprises a first threaded rod 512; a rectangular slot is formed in the fixed plate 51, and the first threaded rod 512 is arranged in the rectangular slot; one end of the first threaded rod 512 extends outward through the fixed plate 51, and a knob 514 is arranged at the extended end of the first threaded rod 512; a moving block 513 is arranged on the first threaded rod 512, and the moving block 513 is threadedly connected to the first threaded rod 512; and the moving block 513 is connected to the support plate 52.

[0034] When it is necessary to adjust the position of the support plate 52, the knob 514 is rotated to drive the first threaded rod 512 to rotate; the moving block 513 is driven to move through the rotation of the first threaded rod 512; and the support plate 52 is driven to move through the moving block 513; thus, the size of the automobile plastic part can be adjusted, and therefore the applicability is high.

[0035] Referring to Figure 6 and Figure 7 As shown in the figure, the adjusting assembly 9 comprises a second threaded rod 91 and a first motor 92; a through slot is formed in the top plate 2, and the second threaded rod 91 is arranged in the through slot; the first motor 92 is arranged on one side of the top plate 2; the output end of the first motor 92 is connected to the second threaded rod 91; a driving block 93 is arranged on the second threaded rod 91; slide rods are arranged on both sides of the second threaded rod 91 in the through slot; a through hole is formed in the driving block 93 for the slide rods to move; a support frame 94 is arranged at the bottom of the driving block 93; a second rotating shaft 95 is arranged in the support frame 94; the two sides of the spray head 8 are arranged in the support frame 94 through the second rotating shaft 95; and a reciprocating swinging component for driving the spray head 8 to swing is arranged on one side of the support frame 94.

[0036] By starting the first motor 92, the second threaded rod 91 is driven to rotate by the first motor 92, and the driving block 93 is moved by the rotation of the second threaded rod 91. At the same time, the aperture on the driving block 93 cooperates with the slide rod to ensure the stability and accuracy of the driving block 93 during movement. Since the nozzle 8 is connected to the support frame 94 through the second shaft 95, the movement of the driving block 93 drives the nozzle 8 to move, thereby realizing accurate adjustment of the position of the nozzle 8. And by setting the reciprocating swing component to drive the nozzle 8 to swing back and forth, the uniformity of spraying is ensured, and the dead angle and missed coating phenomenon in the spraying process is effectively reduced. At the same time, the overall spraying quality has been significantly improved.

[0037] Referring to Figure 6 and Figure 7 , the reciprocating swing component includes a connecting plate 96 and an extension frame 97; one end of the second shaft 95 extends outwardly through the support frame 94, the connecting plate 96 is arranged on the extended end of the second shaft 95, and the connecting plate 96 is provided with an arc-shaped sliding groove; the extension frame 97 is arranged on one side of the driving block 93, and the extension frame 97 is provided with a second motor 98 on one side, and the output end of the second motor 98 is provided with a rotating plate 99, and the rotating plate 99 is provided with a rotating column 910, and the rotating column 910 is arranged in the arc-shaped sliding groove.

[0038] By starting the second motor 98, the connecting plate 96 is driven to rotate by the second motor 98, and the rotating column 910 is driven to rotate by the rotation of the connecting plate 96. Since the rotating column 910 is arranged in the arc-shaped sliding groove, when the rotating column 910 rotates, it will move along the arc-shaped sliding groove, thereby driving the connecting plate 96 to swing along the center of the second shaft 95. The nozzle 8 is swung by the swinging of the connecting plate 96, reducing the dead angle and missed coating phenomenon in the spraying process, and improving the overall spraying quality.

[0039] When the automobile plastic part needs to be clamped, the support plate 52 is driven to move to the appropriate position through the threaded driving part. Then the pull plate 56 is pulled, the movable rod 54 is moved by the pull plate 56, and the pressing plate 55 is moved by the movement of the movable rod 54. The pressing plate 55 will extrude the spring 57 sleeved on the movable rod 54 during the movement, so that the spring 57 is compressed. At this time, the automobile plastic part is placed in the rectangular frame 53, and the spring 57 restores the elastic deformation to drive the pressing plate 55 to move to the automobile plastic part by loosening the pull plate 56, so as to clamp and fix the automobile plastic part. And the automobile plastic part can be clamped and rotated by rotating the driving part to realize the omnibearing rotation of the automobile plastic part and greatly improve the spraying efficiency. By starting the first motor 92, the second threaded rod 91 is rotated by the first motor 92, the driving block 93 is moved by the rotation of the second threaded rod 91, and at the same time, the through hole on the driving block 93 cooperates with the sliding rod to ensure the stability and accuracy of the driving block 93 during the movement.
