Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, and more specifically, to an automatic spraying equipment for automotive trim parts with adjustable spraying range. Background Technology

[0002] Automotive trim serves to decorate and beautify cars, and the quality of its decorative effect directly affects the interior and exterior image of the car. Therefore, during the production of automotive trim, spraying equipment is required to disperse the paint into uniform and fine droplets and apply it to the surface of the object to be coated.

[0003] Currently, the spraying area of ​​the spraying equipment needs to be kept perpendicular to the spraying area of ​​the automotive trim in real time to ensure the uniformity of the spraying. In order to achieve the purpose of complete spraying, the spraying component needs to be repeatedly adjusted to adjust the spraying angle. If the side wall of the automotive trim is tilted inward or at a tricky angle, the spraying angle of the spraying component is limited, and the spraying component is generally only bent at the top of the automotive trim. In this state, the spraying component needs to be tilted upward to spray. The paint droplets sprayed upward will drip downward due to gravity, which will inevitably lead to the contamination of the spraying component by the spraying liquid. Moreover, since automotive trims have different styles and sizes, the existing spraying components cannot complete the spraying work on automotive trims with tricky inward tilted surfaces. If the length of the spraying component is increased to achieve the purpose of spraying, the volume of the spraying component will increase, which will lead to the need to increase the height and width of the factory or spraying booth. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automatic spraying equipment for automotive trim parts with adjustable spraying range.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic spraying device for automotive trim parts with adjustable spraying range, comprising a main body assembly, a conveying assembly disposed inside the main body assembly, a swinging assembly installed on top of the conveying assembly, and a limiting assembly installed on top of the swinging assembly.

[0006] The main component includes a spray booth, the conveying component is installed on the inner bottom wall of the spray booth, a placement seat is installed inside the spray booth and on one side of the conveying component, and the spraying component is installed on the top of the placement seat.

[0007] The swing assembly includes a base rotatably connected to the top of the conveying assembly and two baffles symmetrically mounted on the top of the base. The tops of the two baffles are hinged to swing plates, and the limiting assembly is mounted on the top of the swing plates.

[0008] The limiting component includes a support plate located above the swing plate. Four connecting feet are installed diagonally between the support plate and the swing plate. The top of the support plate has two first inclined portions. Several grooves are formed on the inclined surfaces of the two first inclined portions. Each pair of symmetrical grooves forms a group. A slider is slidably connected inside each groove. A wedge block is installed on the top of the slider. A clamping plate is connected to the top surface of the wedge block. The top of the clamping plate holds the workpiece.

[0009] The present invention is further configured such that the inclined surface and the horizontal surface of the wedge block are arranged vertically, that is, the inclined surface of the wedge block faces downward and is connected to the top of the slider, the horizontal surface of the wedge block faces upward and is connected to the bottom surface of the clamp, and the inclination angle of the inclined surface of the wedge block is consistent with the inclination angle of the first inclined part.

[0010] The present invention is further configured such that: doors are installed on both sides of the spray booth, and a conveying port for conveying materials is opened on one side of each of the two doors; a control cabinet for controlling the operation of the equipment is installed on one side of the spray booth.

[0011] By adopting the above technical solution, the cylinder extends or retracts according to the painting of the car trim, thereby causing the cam protrusion to swing along the hinge point between the cam and the baffle. The cam synchronously drives the connecting frame and the swing plate to swing and tilt synchronously, so that the limiting component installed on the top of the swing plate and the car trim positioned on the limiting component can achieve the purpose of tilt angle adjustment, thereby increasing the painting range of the painting component for the car trim at the tilt angle. In addition, the rotating mechanism drives the base and the various components installed on the top of the base and the limiting component to swing horizontally, thereby achieving the purpose of horizontal angle adjustment, thereby increasing the painting range of the painting component for the car trim at the horizontal angle.

[0012] The present invention is further configured such that: the conveying assembly includes a track and a plurality of ground rail trolleys slidably connected to the top of the track; the track passes through two conveying ports along the length of the spray booth; and each ground rail trolley is equipped with a drive mechanism for driving the displacement of the ground rail trolley.

[0013] The invention is further configured such that: the swing assembly also includes a rotating mechanism installed at the bottom of the ground rail trolley, the output end of the rotating mechanism vertically upward through the ground rail trolley and connected to the base, two cams are hinged between the two baffles, the protrusions of the two cams are arranged downward, a connecting frame is connected between the two cams, the top of the connecting frame is connected to the bottom of the swing plate, a cylinder is installed on one side of one of the baffles, and a locking clamp is hinged to the piston rod end of the cylinder, the locking clamp is engaged with the protrusion at the bottom of the cam.

[0014] By adopting the above technical solution, when the swing assembly drives the limiting assembly and the workpiece to tilt, in order to avoid the workpieces blocking each other and causing some areas to be unable to be sprayed, the swing plate tilts to one side. The bearing fixture corresponding to this tilt direction slides in the opposite direction due to gravity. That is, the bearing fixture on one of the first tilting parts slides to the edge of the bearing plate, while the bearing fixture on the other first tilting part has the same gravity direction as the swing direction of the swing plate, so it remains in the same position. At this time, the distance between the bearing fixtures on the two first tilting parts increases, and the workpieces will not block each other when tilted, and vice versa, thereby achieving the purpose of multiple workpieces being completely sprayed at the same time.

[0015] The present invention is further configured such that: the spraying assembly includes a robotic arm mounted on the top of the placement seat, the output end of the robotic arm is connected to an adjustment mechanism, and the top of the adjustment mechanism is equipped with three sets of nozzle mechanisms.

[0016] The invention is further configured such that: the adjustment mechanism includes a base connected to the output end of the robot arm and a connecting plate connected to the top of the base; the top of the connecting plate has three guide grooves, which are arranged equidistantly; the guide groove in the middle is parallel to the side wall of the connecting plate, while the two guide grooves on both sides are inclined; a guide post is slidably connected inside each guide groove; a slide block is connected to the side of the guide post near the base; a placement plate is connected to the side of the slide block away from the connecting plate; and the three sets of nozzle mechanisms are respectively installed on the three placement plates.

[0017] The present invention is further configured such that: two first linear slide rails are installed on the side of the connecting plate near the base, and second linear slide rails are slidably connected to the side walls of the two first linear slide rails, and the three slide blocks slide along the extension direction of the second linear slide rails.

[0018] The present invention is further configured such that: each of the three sets of nozzle mechanisms includes a spray cavity mounted on a corresponding placement plate, wherein a first nozzle and several second nozzles are mounted on the side of the spray cavity away from the adjustment mechanism, the first nozzle is located at the center of the spray cavity, and several second nozzles are arranged equidistantly around the first nozzle.

[0019] The present invention is further configured such that: a guide rail is installed at the position of each second nozzle, the second nozzle is located inside the corresponding guide rail, a miniature push rod is installed inside each guide rail, the output end of the miniature push rod is connected to the outer wall of the second nozzle, and a second inclined portion is provided on the side of each guide rail near the first nozzle, and the inclination direction of the second nozzle and the miniature push rod is consistent with that of the second inclined portion.

[0020] By adopting the above technical solution, when the guide column slides along the extension direction of the corresponding guide groove, the guide column drives the corresponding slide and placement plate to move synchronously, thereby adjusting the position of the three sets of nozzle mechanisms. By adjusting the spacing between the three sets of nozzle mechanisms, the spraying range is adaptively adjusted for different widths of the workpiece spraying surface, reducing the number of repeated sprayings and improving the spraying efficiency. Furthermore, when the spacing of the three sets of nozzle mechanisms is adjusted, multiple micro push rods push the corresponding second nozzle to move, thereby adjusting the coverage area of ​​each set of nozzle mechanisms and avoiding missed spraying.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] (1) By setting up a swing plate, the cylinder extends or contracts according to the painting of the car trim, thereby driving the cam protrusion to swing along the hinge point between the cam and the baffle. The cam synchronously drives the connecting frame and the swing plate to swing and tilt synchronously, so that the limiting component installed on the top of the swing plate and the car trim achieve the purpose of tilt angle adjustment, increasing the painting range of the painting component for the car trim at the tilt angle, achieving the purpose of complete painting while ensuring that the volume of the painting booth remains unchanged, and reducing the floor area of ​​the painting booth.

[0023] (2) When the swing assembly drives the limiting assembly and the workpiece to tilt, the swing plate tilts to one side, and the bearing fixture on the first tilting part corresponding to the tilting direction slides to the edge of the bearing plate. The gravity direction of the bearing fixture on the other first tilting part is the same as the swinging direction of the swing plate, so the position remains unchanged. The distance between the bearing fixtures on the two first tilting parts increases, and the workpieces will not block each other when tilting, thus achieving the purpose of multiple workpieces being completely sprayed at the same time.

[0024] (3) By adjusting the spacing between the three sets of nozzle mechanisms, the spraying range can be adaptively adjusted for different widths of the workpiece spraying surface, reducing the number of repeated sprayings and improving the spraying efficiency. Furthermore, when adjusting the spacing between the three sets of nozzle mechanisms, multiple micro push rods are used to push the corresponding second nozzle displacement, thereby adjusting the coverage area of ​​each set of nozzle mechanisms and avoiding missed spraying.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0046] Please see Figure 1-13 The present invention provides the following technical solutions:

[0047] Example 1, see Figures 1-3 An automatic spraying equipment for automotive trim parts with adjustable spraying range includes a main component 1, which includes a spraying chamber 11. Doors 13 are installed on both sides of the spraying chamber 11, and the two sides of the spraying chamber 11 are open. The two doors 13 cooperate to cover the openings on both sides of the spraying chamber 11. A conveying port 14 for conveying materials is opened on one side of each of the two doors 13. A conveying component 2 is provided inside the main component 1. The conveying component 2 is used to convey automotive trim parts, so that the automotive trim parts to be sprayed can enter and exit the spraying chamber 11 through the two conveying ports 14 and the conveying component 2, so that the automotive trim parts can complete the spraying operation in the spraying chamber 11.

[0048] See Figures 1-3 The conveying assembly 2 is installed on the inner bottom wall of the spray booth 11. The conveying assembly 2 includes a track 21 and several ground rail trolleys 22 slidably connected to the top of the track 21. The track 21 passes through two conveying ports 14 along the length of the spray booth 11. Each ground rail trolley 22 is equipped with a drive mechanism 23 for driving the displacement of the ground rail trolley 22. Both ends of the track 21 extend to the outside of the spray booth 11. The ground rail trolleys 22 are driven by the corresponding drive mechanism 23 and enter the interior of the spray booth 11 through one end of the track 21 and the corresponding conveying port 14. Several ground rail trolleys 22 enter in sequence. Then, the ground rail trolleys 22 move out of the spray booth 11 through the other end of the track 21 and the corresponding conveying port 14. During the movement of the ground rail trolleys 22, the automotive trim parts to be sprayed are simultaneously brought into the spray booth 11. The automotive trim parts are sprayed inside the spray booth 11.

[0049] See Figure 3 and Figure 4 A swing assembly 3 is installed on top of the conveying assembly 2, and a limiting assembly 4 is installed on top of the swing assembly 3. A placement seat 5 is installed inside the spray booth 11 and on one side of the conveying assembly 2. A spraying assembly 6 is installed on top of the placement seat 5. The limiting assembly 4 is used to support the automotive trim parts, and both the limiting assembly 4 and the automotive trim parts are supported by the swing assembly 3. The placement seat 5 is used to position and install the spraying assembly 6. When the ground rail trolley 22 moves to the position of the spraying assembly 6, the spraying assembly 6 performs a spraying operation on the surface of the automotive trim parts. The spraying area of ​​the spraying assembly 6 must remain perpendicular to the spraying area of ​​the automotive trim parts in real time to ensure uniform spraying. To achieve complete spraying... The purpose is to repeatedly adjust the spraying angle of the spraying component 6. If the side wall of the car trim has a tricky inward tilt angle, the spraying angle of the spraying component 6 is limited. The spraying component 6 needs to be repeatedly bent on the top of the car trim to achieve the purpose of spraying this surface. However, in this state, the spraying component 6 will tilt upward to spray, which can easily cause the spraying liquid to contaminate the spraying component 6. Moreover, since the car trim has different volumes, the spraying component 6 cannot adapt to the spraying of different tricky tilted surfaces of car trim. If the length of the spraying component 6 is increased to achieve the purpose of spraying, the volume of the spraying component 6 will increase, which will result in the need to increase the height and width of the factory or spraying booth 11.

[0050] To achieve complete painting while keeping the volume of the spray booth 11 unchanged, the swing component 3 drives the limiting component 4 and the automotive trim parts to swing horizontally and tilt vertically. This adjusts the angle of the automotive trim parts, indirectly increasing the painting range of the spraying component 6 and reducing the floor space of the spray booth 11. The specific structure and swing method of the swing component 3 are as follows:

[0051] See Figures 9-10 The swing assembly 3 includes a base 31 rotatably connected to the top of the conveying assembly 2 and two baffles 34 symmetrically mounted on the top of the base 31. Two cams 37 are hinged between the two baffles 34, with the protrusions of the two cams 37 facing downwards. A connecting frame 38 is connected between the two cams 37, and a swing plate 32 is connected to the top of the connecting frame 38. A cylinder 35 is mounted on one side of one baffle 34. A locking clamp 36 is hinged to the piston rod end of the cylinder 35. The locking clamp 36 is engaged with the protrusion at the bottom of the cam 37. By extending or retracting the piston rod of the cylinder 35, the protrusion of the cam 37 is driven to swing along the hinge point between the cam 37 and the baffle 34. The cam 37 synchronously drives the connecting frame 38 and the swing plate 32 to swing and tilt synchronously, so that the limiting assembly 4 mounted on the top of the swing plate 32 and the automotive trim positioned on the limiting assembly 4 achieve the purpose of tilt angle adjustment, thereby increasing the spraying range of the spraying assembly 6 for the automotive trim at the tilt angle.

[0052] See Figures 9-10 The swing assembly 3 also includes a rotating mechanism 33 installed at the bottom of the ground rail trolley 22. The output end of the rotating mechanism 33 extends vertically upward through the ground rail trolley 22 and is connected to the base 31. When the swing plate 32 drives the limiting assembly 4 and the automotive trim to adjust the angle, the rotating mechanism 33 drives the base 31 and the various components installed on the top of the base 31 and the limiting assembly 4 to swing horizontally, thereby achieving the purpose of horizontal angle adjustment and increasing the spraying range of the spraying assembly 6 for the automotive trim in the horizontal angle.

[0053] Specifically, the staff places the car accessories to be painted on the limiting component 4 and fixes them. Then, the ground rail trolley 22 slides on the track 21, causing the car accessories to be sent into the interior of the spray booth 11. Multiple ground rail trolleys 22 are operated in sequence to step into the spray booth 11. When the car accessories move to the position of the spraying component 6, all ground rail trolleys 22 stop moving. The spraying component 6 sprays the surface of the nearby car accessories, and the process is repeated.

[0054] Furthermore, during the spraying operation, the spraying assembly 6 uses the control cabinet 12 to control the operation of the cylinder 35 corresponding to the car trim being sprayed. The cylinder 35 extends or retracts according to the spraying situation of the car trim, thereby causing the protrusion of the cam 37 to swing along the hinge point between the cam 37 and the baffle 34. The cam 37 synchronously drives the connecting frame 38 and the swing plate 32 to swing and tilt synchronously, so that the limiting component 4 installed on the top of the swing plate 32 and the car trim positioned on the limiting component 4 achieve the purpose of tilt angle adjustment, increasing the spraying range of the spraying assembly 6 for the car trim at the tilt angle. In addition, the rotating mechanism 33 drives the base 31 and the various components installed on the top of the base 31 and the limiting component 4 to swing horizontally, thereby achieving the purpose of horizontal angle adjustment, increasing the spraying range of the spraying assembly 6 for the car trim at the horizontal angle. After the car trim is sprayed, it is sent out of the spraying booth 11 by the corresponding ground rail trolley 22, and the staff can remove the car trim from the ground rail trolley 22.

[0055] Example 2, see Figures 9-12The limiting component 4 includes a support plate 42, which is located above the swing plate 32. Four connecting feet 41 are installed diagonally between the support plate 42 and the swing plate 32. The connecting feet 41 and the support plate 42 cooperate to form a support platform. Multiple automotive trim parts can be placed on this support platform. The top of the support plate 42 is provided with two first inclined portions 48. Several sliding grooves 43 are opened on the inclined surfaces of the two first inclined portions 48. Each pair of symmetrical sliding grooves 43 forms a group. A slider 44 is slidably connected inside each sliding groove 43. A wedge block 45 is installed on the top of the slider 44. A clamping plate 46 is connected to the top surface of the wedge block 45. The top of the clamping plate 46 clamps the workpiece 47. The aforementioned automotive trim parts are all workpieces 47. The slider 44, wedge block 45 and clamping plate 46 cooperate to form a support fixture for clamping the workpiece 47. Multiple sets of support fixtures are provided on the support plate 42. The two sets of support fixtures corresponding to the two first inclined portions 48 form a group. The workpieces 47 are placed in pairs.

[0056] See Figures 10-11 The inclined surface and the horizontal surface of the wedge block 45 are arranged vertically, that is, the inclined surface of the wedge block 45 faces downward and is connected to the top of the slider 44, and the horizontal surface of the wedge block 45 faces upward and is connected to the bottom surface of the clamp 46. The inclination angle of the inclined surface of the wedge block 45 is the same as the inclination angle of the first inclined part 48. Since the slider 44 slides in the groove 43 opened on the first inclined part 48, the sliding direction of the slider 44 is inclined. The two sets of corresponding bearing fixtures slide closer to each other due to the influence of gravity and the inclination of the first inclined part 48. However, since the slider 44 slides at an inclination, in order to ensure that the workpiece 47 is placed horizontally, the wedge block 45 is used to compensate for the inclination angle of the first inclined part 48 and the slider 44. The workpiece 47 maintains its horizontal state during the displacement process.

[0057] Specifically, the staff places the car trim to be sprayed, i.e. workpiece 47, on the corresponding clamp 46. The two sets of corresponding bearing clamps slide closer to each other due to the influence of gravity and the inclination of the first inclined part 48, causing the two workpieces 47 to be arranged close to each other, reducing the area repeatedly sprayed by the spraying component 6.

[0058] like Figure 13As shown, there is a side wall C with a tricky inward tilt angle in the middle of the workpiece 47. When spraying at this position, the spraying component 6 needs to be placed on the side of this position to be fully sprayed. However, when the swing component 3 drives the limiting component 4 and the workpiece 47 to tilt, the workpieces 47 block each other, making it impossible to spray at this position. In order to avoid this situation, the swing plate 32 tilts to one side, and the bearing fixture corresponding to this tilt direction slides in the opposite direction due to gravity. That is, the bearing fixture on one first tilting part 48 slides to the edge of the bearing plate 42, while the bearing fixture on the other first tilting part 48 has the same gravity direction as the swing direction of the swing plate 32, so it remains in the same position. At this time, the distance between the bearing fixtures on the two first tilting parts 48 increases, and the workpieces 47 will not block each other when tilted, and vice versa, thereby achieving the purpose of simultaneously and completely spraying multiple workpieces 47.

[0059] Example 3, see Figure 4 The spraying assembly 6 includes a robotic arm 61 mounted on top of the placement base 5. The output end of the robotic arm 61 is connected to an adjustment mechanism 62. Three sets of nozzle mechanisms 63 are mounted on top of the adjustment mechanism 62. The robotic arm 61 drives the adjustment mechanism 62 and the nozzle mechanisms 63 to synchronously adjust their displacement and angle, enabling the nozzle mechanisms 63 to spray different positions on the workpiece 47. The adjustment mechanism 62 is used to adjust the spacing between the multiple sets of nozzle mechanisms 63, thereby adjusting the spraying range of the multiple sets of nozzle mechanisms 63. The specific structure and adjustment method of the adjustment mechanism 62 are as follows:

[0060] See Figure 5 The adjustment mechanism 62 includes a base 621 connected to the output end of the robot arm 61 and a connecting plate 622 connected to the top of the base 621. The top of the connecting plate 622 has three guide grooves 623, which are equidistantly arranged. Each guide groove 623 has a guide post 624 slidably connected inside it. A slide block 628 is connected to the side of the guide post 624 closest to the base 621, and a placement plate 625 is connected to the side of the slide block 628 furthest from the connecting plate 622. Three sets of nozzle mechanisms 63 are respectively installed on the three placement plates 625. When the guide post 624 slides along the extension direction of the corresponding guide groove 623, the guide post 624 drives the corresponding slide block 628. The guide groove 623 in the middle is parallel to the side wall of the connecting plate 622, while the two guide grooves 623 on both sides are inclined in opposite directions. Since the guide groove 623 guides the corresponding guide post 624, the slide 628 and the placement plate 625 corresponding to the middle guide groove 623 are linearly displaced, while the slide 628 and the placement plate 625 corresponding to the inclined guide grooves 623 on both sides are inclinedly displaced, causing the three sets of nozzle mechanisms 63 to move closer to each other or further away from each other during displacement, thereby achieving the purpose of adjusting the spraying range of the three sets of nozzle mechanisms 63.

[0061] See Figure 5 Two first linear slide rails 626 are installed on the side of the connecting plate 622 near the base 621. The side walls of the two first linear slide rails 626 are slidably connected to second linear slide rails 627. Three slide blocks 628 slide along the extension direction of the second linear slide rails 627. The first linear slide rails 626 are used to drive the displacement of the second linear slide rails 627 and the three slide blocks 628. During the sliding process along the extension direction of the first linear slide rails 626, the three slide blocks 628 are affected by the cooperation of the guide post 624 and the guide groove 623, causing the slide blocks 628 to slide in the extension direction of the second linear slide rails 627. This setting provides driving force for the spraying range adjustment of the three sets of nozzle mechanisms 63.

[0062] See Figure 6 Each of the three nozzle mechanisms 63 includes a spray cavity 631 mounted on a corresponding placement plate 625. A first nozzle 632 and several second nozzles 634 are mounted on the side of the spray cavity 631 away from the adjustment mechanism 62. The first nozzle 632 is located at the center of the spray cavity 631, and several second nozzles 634 are arranged equidistantly around the first nozzle 632. The spray cavity 631 is connected to an external material supply device, causing paint to be discharged into the interior of the spray cavity 631. The first nozzle 632 and the second nozzles 634 cooperate to spray the paint inside the spray cavity 631. By setting several second nozzles 634, the spraying range is greatly increased.

[0063] See Figure 6 Each second nozzle 634 is equipped with a guide rail 633, and the second nozzle 634 is located inside the corresponding guide rail 633. Each guide rail 633 is equipped with a miniature push rod 635, and the output end of the miniature push rod 635 is connected to the outer wall of the second nozzle 634. Each guide rail 633 has a second inclined portion 636 on the side near the first nozzle 632. The second nozzle 634 and the miniature push rod 635 are inclined in the same direction as the second inclined portion 636. The miniature push rod 635 drives the second nozzle 634 to slide on the second inclined portion 636 of the guide rail 633, thereby adjusting the spray range of the second nozzle 634. That is, when the piston rod of the miniature push rod 635 extends, the distance between the second nozzle 634 and the first nozzle 632 increases, thereby increasing the spray range. When the piston rod of the miniature push rod 635 retracts, the distance between the second nozzle 634 and the first nozzle 632 decreases, thereby decreasing the spray range.

[0064] Specifically, by adjusting the spacing between the three sets of nozzle mechanisms 63, the spraying range is adaptively adjusted for different widths of the spraying surface of the workpiece 47, reducing the number of repeated sprayings and improving spraying efficiency. Furthermore, when adjusting the spacing between the three sets of nozzle mechanisms 63, multiple micro push rods 635 push the corresponding second nozzle 634 to move, thereby adjusting the coverage area of ​​each set of nozzle mechanisms 63 and avoiding missed spraying.

[0065] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
