DETAILED DESCRIPTION

[0073] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0074] Embodiment 1, a coating spraying machine for manufacturing automobile exterior decoration parts, comprising a workbench 81, such as Figure 1-Figure 2 , Figure 15-16A spray gun body 82 is arranged above the workbench 81. The head of the spray gun body 82 is a nozzle, and the paint is sprayed from the nozzle to fully spray the workpiece. The middle bottom end of the spray gun body 82 is fixedly connected with a branch pipe 83, which can provide a path for the paint to enter the spray gun body 82. The workbench 81 is internally movably sleeved with a feed box 85, which can provide a storage space for the paint. The top of the feed box 85 is fixedly connected to the bottom of the branch pipe 83 through a feed pipe 86, and the paint in the feed box 85 can be transported to the branch pipe 83 by the feed pipe 86. The workbench 81 is internally movably sleeved with an air pump 87, which can provide a generation space for compressed air. The top of the air pump 87 is fixedly connected to the tail of the spray gun body 82 through an air pipe 88, and the air pipe 88 can be used to The compressed air in the air pump 87 is transported to the spray gun body 82, so that the workbench 81, the spray gun body 82, the branch pipe 83, the feed box 85, the feed pipe 86, the air pump 87 and the air pipe 88 constitute a spray mechanism 8 for spraying the workpiece. In summary, when the moving mechanism 3 drives the workpiece to move to the spray mechanism 8, the spray mechanism 8 can spray the workpiece. Specifically, first, the paint in the feed box 85 enters the branch pipe 83 through the feed pipe 86, and at the same time, the compressed air in the air pump 87 enters the tail of the spray gun body 82 through the air pipe 88, and then the compressed air moves from the back to the front in the spray gun body 82, so that the paint moves at high speed with the compressed air, and is atomized and sprayed out from the nozzle of the spray gun body 82, so that it is evenly sprayed on the surface of the workpiece to achieve spraying of the workpiece.

[0075] like Figure 1 , Figure 5 , two moving tracks 1 are arranged on one side of the spraying mechanism 8, and the two moving tracks 1 are arranged symmetrically to provide a path for the movement of the workpiece, such as Figure 9-13 The right blocking plate 2a is arranged at the top of a movable track 1 close to the spraying mechanism 8. A fixing hole is opened in the middle of the right blocking plate 2a, and the middle of the fixing hole of the right blocking plate 2a is fixedly sleeved with the outer ring of the rubber ring 20, and the inner ring of the rubber ring 20 is fixedly sleeved with the head of the spray gun body 82, so as to provide stable support for the head of the spray gun body 82.

[0076] like Figure 9-11 , Fig.14 The right blocking plate 2a is provided with an auxiliary mechanism for cleaning the agglomerated paint in the nozzle, and the auxiliary mechanism includes a movable component 5, a rotating component 6 and a pushing component 7, such as Figure 1-Figure 2 , Figure 4A fixing groove is provided on one side of the right blocking plate 2a, and the fixing groove is located on the side of the right blocking plate 2a away from the spraying mechanism 8, the fixing groove is located outside the fixing hole, and the fixing groove and the fixing hole are concentrically arranged, which can provide conditions for the movable component 5 to rotate concentrically around the spray gun body 82, and the right blocking plate 2a is provided with a movable component 5 through the fixing groove, and a rotating component 6 is movably arranged on the lower outer side of the movable component 5, and a pushing component 7 is movably arranged on the wall of the movable component 5. When the nozzle needs to be cleaned, the pushing component 7 is used to control the movable component 5 to be inserted into the nozzle, and then the rotating component 6 is used to control the movable component 5 to rotate, so that the movable component 5 cleans the inner wall of the nozzle, specifically:

[0077] like Figure 10-11 , Fig.14 The movable assembly 5 is a component for cleaning the nozzle, and the movable assembly 5 includes a movable ring 51 and a movable part 52. The movable ring 51 is in the shape of a ring, and the movable ring 51 is movably sleeved in the fixed groove of the right blocking plate 2a. The movable part 52 is in the shape of a U-shape with unequal lengths on both sides. The longer section of the movable part 52 is fixedly connected to a side wall of the movable ring 51, and the shorter section of the movable part 52 corresponds to the position of the inner wall of the nozzle of the spray gun body 82. When the movable ring 51 is located at different positions in the fixed groove, the position of the shorter section of the movable part 52 relative to the nozzle of the spray gun body 82 can be changed, thereby realizing different functions, that is, during spraying, ensuring that the shorter section of the movable part 52 The movable part 52 does not contact with the spray gun body 82 to prevent the deflection of the spray gun body 82. When cleaning, ensure that the shorter section of the movable part 52 is in contact with the spray gun body 82 to achieve cleaning of the nozzle. The number of movable parts 52 is two, and the two movable parts 52 are symmetrically arranged on the side of the right blocking plate 2a away from the spraying mechanism 8. The end of the shorter section of the movable part 52 is inclined, which can facilitate the movable part 52 to be better inserted into the nozzle to remove the agglomerated paint. The wall surface of the movable part 52 near the center of the fixed groove is provided with a threaded groove, which can effectively and fully disturb the paint during spraying, so that the paint is evenly diffused to the surface of the workpiece, further improving the uniformity of the workpiece spraying.

[0078] like Figure 9-11 , Fig.14 The rotating assembly 6 is a power component for controlling the self-rotation of the movable assembly 5, and the rotating assembly 6 includes a rotating motor 61 and a rotating shaft 62. The lower half of the right blocking plate 2a is fixedly sleeved with the rotating motor 61. A rotating cavity is provided inside the right blocking plate 2a, and the right blocking plate 2a is movably sleeved with the rotating shaft 62 through the rotating cavity. The rotating cavity is connected to the fixed groove. A tooth groove is provided on the outer ring of the movable ring 51, and the movable ring 51 is meshed with the outer wall of the rotating shaft 62 through the tooth groove, so that the rotation of the rotating shaft 62 can drive the movable ring 51 to rotate, and then the movable part 52 rotates. One end of the rotating motor 61 is movably connected to one end of the rotating shaft 62, and the length of the rotating shaft 62 is larger than the width of the fixed groove, which can ensure that the movable ring 51 is always meshed with the rotating shaft 62.

[0079] like Figure 9-11 , Fig.14 The pushing component 7 is a power component for controlling the left and right movement of the movable component 5, and the pushing component 7 includes a pushing cylinder 71 and a pushing rod 72. The pushing cylinder 71 is fixedly sleeved on the right blocking plate 2a, and the pushing cylinder 71 and the spraying mechanism 8 are located on the same side of the right blocking plate 2a. There are two pushing cylinders 71, and the two pushing cylinders 71 are respectively arranged on both sides of the spray gun body 82, so as to facilitate and stably control the horizontal movement of the movable component 5 in the fixed groove. One end of the pushing rod 72 is movably sleeved with the pushing cylinder 71, and a ring groove is provided on one side of the movable ring 51, and the movable ring 51 is movably clamped with the other end of the pushing rod 72 through the ring groove.

[0080] In summary, when the nozzle needs to be cleaned, first start the push cylinder 71 to make the push rod 72 move into the push cylinder 71. At this time, the movable ring 51 is driven to move in the fixed groove toward the tail end of the spray gun body 82, thereby driving the movable part 52 to move and insert into the nozzle, so that the side wall of the movable part 52 fits with the inner wall of the spray gun body 82, thereby preparing for cleaning the inner wall of the nozzle of the spray gun body 82. It should be noted that the spray gun body 82 is in a horizontal state at this time, and then the rotating motor 61 is started to rotate the rotating shaft 62, thereby driving the movable ring 51 to rotate, so that the inserted movable part 52 can fully clean the paint agglomerated in the nozzle of the spray gun body 82.

[0081] When spraying, first start the push cylinder 71 to make the push rod 72 move out of the push cylinder 71. At this time, the movable ring 51 is driven to move in the fixed groove toward the tail direction away from the spray gun body 82, thereby driving the movable part 52 to move and move out of the nozzle, so that the movable part 52 does not contact the head of the spray gun body 82. Then start the rotating motor 61 to rotate the rotating shaft 62, thereby driving the movable ring 51 and the movable part 52 to rotate, effectively disturbing the sprayed paint, so that the paint is evenly diffused to the workpiece surface, and the uniformity of the workpiece spraying is improved.

[0082] Embodiment 2, based on embodiment 1, as Figure 4 , Figure 11-13 The fixing hole of the right blocking plate 2a is in the shape of a trumpet with large ends and a small middle portion, which can provide the head of the spray gun body 82 with sufficient deflection space to achieve the spray direction conversion of the spray gun body 82 nozzle.

[0083] The spraying mechanism 8 also includes a limiting ring 84 and a supporting assembly 9, specifically:

[0084] like Fig.16 The outer wall of the rear end of the spray gun body 82 is fixedly connected to two limiting rings 84, which can provide conditions for the stable setting of the rear end of the spray gun body 82.

[0085] like Fig.15 Two sets of support components 9 are arranged at the top of the workbench 81, and the two sets of support components 9 are arranged symmetrically. The tail of the spray gun body 82 is movably arranged between the two sets of support components 9, which is used to provide stable support for the tail of the spray gun body 82 and provide power for regulating the spraying direction of the spray gun body 82. The support component 9 includes a support plate 91, a support rod 92, a hydraulic cylinder 93, a hydraulic rod 94 and a hydraulic plate 95. Fig.17 The support plate 91 is fixedly arranged on the top of the workbench 81, and an arc groove is opened on the wall of the support plate 91 close to the spray gun body 82. One end of the support rod 92 is movably engaged with the inner part of the limit ring 84, and the other end of the support rod 92 is movably engaged with the arc groove of the support plate 91. When the support rod 92 moves along the arc groove, since the head of the spray gun body 82 is fixed by the rubber ring 20, the movement of the support rod 92 will cause the tail of the spray gun body 82 to deflect, thereby changing the deflection position of the head of the spray gun body 82, thereby realizing the change of the spraying direction of the spray gun body 82. The hydraulic The bottom end of the cylinder 93 is fixedly connected to the bottom end of the workbench 81, the top end of the hydraulic cylinder 93 is movably connected to the bottom end of the hydraulic rod 94, the top end of the hydraulic rod 94 is fixedly connected to the bottom end of the hydraulic plate 95, the top end of the hydraulic plate 95 is provided with a groove, and the support rod 92 is placed in the groove of the hydraulic plate 95. When the hydraulic cylinder 93 controls the hydraulic rod 94 and the hydraulic plate 95 to move up and down, the hydraulic plate 95 pushes the support rod 92 to move up and down. Since the movement of the support rod 92 is limited by the arc groove of the support plate 91, the support rod 92 will move left and right in the groove of the hydraulic plate 95.

[0086] In summary, the hydraulic cylinder 93, the hydraulic rod 94 and the hydraulic plate 95 are controlled to move slowly up and down, effectively pushing the support rod 92 to move along the arc groove of the support plate 91, thereby driving the spray gun body 82 to deflect up and down, so that the nozzle of the spray gun body 82 is deflected along the rubber ring 20, thereby controlling the change of the nozzle angle of the spray gun body 82, that is, automatically changing the up and down spraying direction of the spray gun body 82, and realizing sufficient vertical spraying of the workpiece.

[0087] Embodiment 3, based on embodiment 2, a coating spraying machine for manufacturing automobile exterior decoration parts further includes a left blocking plate 2b, specifically, as shown in FIG. Figure 1 , Fig. 9The right baffle plate 2a is fixedly arranged on a moving track 1, and the left baffle plate 2b is arranged on another moving track 1. The right baffle plate 2a and the left baffle plate 2b are symmetrically arranged, and the right baffle plate 2a and the left baffle plate 2b are in the shape of a quarter ring. The right baffle plate 2a and the left baffle plate 2b can be used to fully surround the workpiece, so that the paint is confined between the right baffle plate 2a and the left baffle plate 2b, effectively blocking the paint from escaping and reducing the impact on the surrounding environment. It should be noted that the left baffle plate 2b is a complete component without holes and components. In addition, heating tubes can be arranged inside the right baffle plate 2a and the left baffle plate 2b, so that the rotating workpiece can be heated after spraying is completed to accelerate the curing of the workpiece.

[0088] Embodiment 4, based on embodiment 3, a coating spraying machine for manufacturing automobile exterior decoration parts, further includes a moving mechanism 3 and a rotating mechanism 4, specifically:

[0089] like Figure 1-Figure 3 A moving mechanism 3 is provided between the two moving rails 1 to provide power conditions for moving the workpiece. The moving mechanism 3 includes a moving seat 31, a moving plate 32, a moving block 33 and a power rope 34. Figure 5-Figure 7 , Fig.14A movable seat 31 is movably arranged between the two movable rails 1, and the number of movable seats 31 is several. A movable disk 32 is movably sleeved in the middle of the movable seat 31. The movable disk 32 includes a circular disk 321, a vertical shaft 322 and a rotating member 323. The circular disk 321 is arranged at the top of the movable seat 31 for placing a workpiece. The outer wall of the vertical shaft 322 is movably sleeved with the movable seat 31, and one end of the vertical shaft 322 is fixedly connected to the bottom end of the circular disk 321, and the other end of the vertical shaft 322 is fixedly connected to the top of the rotating member 323. When the rotating member 323 rotates, it will drive the vertical shaft 322 and the circular disk 321 to rotate synchronously, so that the workpiece rotates at a uniform speed, and then the coating spraying is coordinated with the self-rotation of the workpiece, effectively realizing the full horizontal spraying of the workpiece, and a main groove is provided at the bottom end of the rotating member 323, and two auxiliary grooves are provided on the wall surface of the rotating member 323 located on the side of the main groove, and the auxiliary grooves are connected to the main groove, and the two auxiliary grooves rotate around The center of the circle of the part 323 is evenly set, which can provide connection conditions for the rotating mechanism 4 to push the moving disk 32 to rotate. The two ends of the moving seat 31 are fixedly connected with the moving blocks 33, and the side walls of the two moving rails 1 are provided with moving grooves, and the moving rail 1 is movably connected with the moving block 33 through the moving groove, effectively ensuring the stability of the setting of the moving seat 31, and the wall of the moving block 33 is movably connected with a pulley, and the pulley fits the moving groove of the moving rail 1, effectively reducing the resistance of the moving block 33 to move in the moving groove of the moving rail 1, and the outer wall of the power rope 34 is fixedly sleeved with the middle part of the moving block 33, and the power rope 34 can control the synchronous movement of several moving seats 31, that is, to provide power for the moving seat 31 to move on the moving rail 1. In summary, when the power rope 34 is started, the power rope 34 can drive the moving seat 31 loaded with workpieces to move along the moving rail 1, so that several workpieces can be sprayed in an orderly manner.

[0090] like Figure 1-Figure 3 A rotating mechanism 4 is provided between the right blocking plate 2a and the left blocking plate 2b for providing power conditions for uniformly spraying the workpiece. The rotating mechanism 4 includes a rotating motor 41, a rotating shaft 42 and a rotating block 43. Figure 5-Figure 6 , Figure 8, the rotating motor 41 is arranged between the right blocking plate 2a and the left blocking plate 2b, and the rotating motor 41 is located below the moving mechanism 3, one end of the rotating shaft 42 is movably engaged with the main groove of the rotating member 323, and the other end of the rotating shaft 42 is movably connected with the top of the rotating motor 41, one end of the rotating shaft 42 is fixedly connected with two rotating blocks 43, and the rotating blocks 43 are movably engaged with the secondary groove of the rotating member 323. When the workpiece needs to be sprayed, the moving disk 32 is moved between the right blocking plate 2a and the left blocking plate 2b, so that the rotating shaft 42 moves to the main groove position of the rotating member 323, and the rotating block 43 is located in the main groove, and then the rotating motor 41 is slowly started to rotate the rotating shaft 42 90 degrees, so that the rotating block 43 rotates into the secondary groove. At this time, the moving disk 32 is stably engaged with the rotating mechanism 4, and then the rotating motor 4 1 works normally, driving the rotating shaft 42 and the rotating block 43 to rotate, thereby driving the moving disk 32 to rotate, and then driving the workpiece to rotate evenly and be sprayed. After the spraying is completed, the rotating motor 41 stops, and then the rotating motor 41 is slowly started and the rotating shaft 42 is rotated 90 degrees in the opposite direction, so that the rotating block 43 rotates back into the main groove, and then the moving disk 32 can move and disengage from the rotating mechanism 4, and drive the workpiece to move to the next stage, thereby achieving sufficient horizontal spraying of the workpiece. In summary, through the coordination of vertical spraying and horizontal spraying of the workpiece, not only the uniformity of the workpiece spraying is improved, but also the cumbersomeness of the staff's operation is reduced. It should be noted that the rotation speed of the rotating motor 41 during normal rotation and the moving speed of the hydraulic cylinder 93 are both regulated by the control system, and the two cooperate with each other to ensure that the surface of the workpiece is evenly sprayed.

[0091] The working principle of the method of the present invention is as follows:

[0092] Before spraying, first place the workpiece stably on the top of the disc 321, then control the movement of the power rope 34, so as to drive the moving seat 31 on which the workpiece is placed to move between the right blocking plate 2a and the left blocking plate 2b, and align the moving disc 32 with the rotating mechanism 4, that is, the rotating shaft 42 and the rotating block 43 are located in the main groove of the rotating part 323, thereby preparing for the rotating mechanism 4 to drive the moving disc 32 to rotate. At the same time, start the push cylinder 71 to control the push rod 72 to move away from the tail of the spray gun body 82, thereby driving the movable ring 51 and the movable part 52 away from the head of the spray gun body 82 to prevent the movable component 5 from affecting the deflection of the head of the spray mechanism 8 during spraying.

[0093] During spraying, the spray mechanism 8 is first started, so that the spray gun body 82 sprays paint outward from the nozzle. In this process, the hydraulic cylinder 93 is started, and the hydraulic rod 94 and the hydraulic plate 95 are controlled to move up and down, thereby pushing the support rod 92 to move along the arc groove of the support plate 91, so that the tail of the spray gun body 82 is regularly deflected, so that the nozzle angle of the spray gun body 82 is changed, thereby automatically changing the up and down spraying direction of the spray gun body 82, and realizing full vertical spraying of the workpiece. At the same time, the rotating motor 41 is slowly started to drive the rotating shaft 42 to rotate 90 degrees, so that the rotating block 43 is engaged with the auxiliary groove of the rotating member 323, and then rotates The motor 41 drives the rotating shaft 42 and the rotating block 43 to rotate normally. Due to the active connection between the rotating mechanism 4 and the movable disk 32, the movable disk 32 is effectively driven to rotate, so that the workpiece rotates at a uniform speed, and sufficient lateral spraying of the workpiece is achieved. This not only improves the uniformity of the workpiece spraying, but also reduces the tediousness of the operation of the staff. In addition, during the spraying process, the rotating motor 61 is started to control the rotation of the rotating shaft 62. Since the rotating shaft 62 is engaged with the movable ring 51, the movable ring 51 and the movable part 52 are rotated, which effectively disturbs the sprayed paint, makes the paint evenly diffuse to the workpiece surface, and further improves the uniformity of the workpiece spraying.

[0094] After spraying, the spraying mechanism 8 stops spraying, the supporting assembly 9 stops disturbing the spray material, the rotating assembly 6 stops driving the movable assembly 5 to rotate, and the rotating mechanism 4 also stops driving the movable disk 32 to rotate. Then the rotating motor 41 starts slowly and drives the rotating shaft 42 to rotate 90 degrees in the opposite direction, so that the rotating block 43 is located in the main groove of the rotating part 323. Finally, the moving seat 31 can be controlled to move by the power rope 34, thereby driving the workpiece to move to the next stage.

[0095] When the nozzle needs to be cleaned, first start the support assembly 9 to adjust the angle of the spray gun body 82 so that the spray gun body 82 is in a horizontal state, and then start the push cylinder 71 to control the push rod 72 to move toward the tail end of the spray gun body 82, thereby driving the movable ring 51 and the movable part 52 to approach the head of the spray gun body 82, and inserting the movable part 52 into the inner wall of the nozzle of the spray gun body 82, and then start the rotating motor 61 to control the rotation of the rotating shaft 62. Since the rotating shaft 62 is engaged with the movable ring 51, the movable ring 51 and the movable part 52 are self-rotated, and the movable part 52 will rotate along the inner wall of the nozzle, effectively cleaning the agglomerated paint adhering to the inner wall of the nozzle, thereby preventing the nozzle of the spray gun body 82 from being blocked and affecting use. After cleaning is completed, the movable assembly 5 can be withdrawn from the interior of the spray gun body 82, and then the nozzle of the spray gun body 82 is deflected downward, thereby realizing the discharge of the paint blocks in the spray gun body 82.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
