[0001] This utility model relates to the field of automotive interior parts spraying technology, and in particular to a spraying device for automotive interior parts. Background Technology

[0002] Automotive interior parts mainly refer to automotive products used for modifying the interior of a car, covering all aspects of the car's interior, such as steering wheel covers, car seat cushions, car floor mats, car perfumes, car pendants, interior decorations, and storage boxes, etc.

[0003] A search revealed Chinese Patent Publication No. CN118950324A, which discloses a painting device for automotive interior parts. This device includes a painting booth with an opening on the side, a loading station outside the painting booth, a painting station inside the painting booth, and a conveying structure for transferring workpieces from the loading station to the painting station. In use, this device delivers the automotive interior part storage box to the underside of the painting end (spray head) via a placement platform on a feeding tray. However, during operation, the device cannot achieve parallel continuous operation of painting and loading / unloading, resulting in interruptions in the production cycle. Furthermore, it lacks a workpiece posture adjustment mechanism during painting. When double-sided painting of the interior parts is required, manual flipping is necessary after single-sided processing, significantly impacting the overall painting efficiency and failing to meet production needs. Therefore, this paper proposes a painting device for automotive interior parts to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a spraying device for automotive interior parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A painting device for automotive interior parts includes a mounting frame, a painting box at the top of the mounting frame, a first motor at the bottom of the mounting frame, an output shaft of the first motor extending through the top of the mounting frame and having a material conveying tray thereon, a painting mechanism extending through the outside of the painting box and located above the material conveying tray, two material feeding and carrying assemblies inside the material conveying tray, and an adjustment and flipping mechanism extending into the material feeding and carrying assemblies inside the material conveying tray.

[0007] The material feeding and carrying assembly includes two placement frames, which are fixedly installed inside the material conveying tray. A connecting frame located below the placement frame is fixedly installed at the bottom of the material conveying tray. An electric telescopic rod is fixedly installed at the bottom of the connecting frame. The output end of the electric telescopic rod passes through the connecting frame and is fixedly connected to a carrying plate that fits against the inner wall of the placement frame.

[0008] Preferably, the spraying mechanism includes a threaded rod, which is rotatably mounted between the left and right sides of the inner wall of the spraying box. Guide rods located on both sides of the threaded rod are fixedly mounted between the left and right sides of the inner wall of the spraying box. A control motor is fixedly mounted on the right side of the spraying box. The output shaft of the control motor is fixedly connected to the threaded rod. A threaded block fitted around the two guide rods is threadedly mounted on the outer side of the threaded rod. A spray head that penetrates to the bottom and extends to the outside of the spraying box is fixedly mounted on the top of the threaded block.

[0009] Preferably, the adjusting and flipping mechanism includes a threaded column, which is rotatably installed inside the conveying tray and located on both sides of the placement frame. A threaded sleeve is threadedly installed on the outer side of the threaded column, and a fixing frame is fixedly connected to one end of the threaded sleeve. A flipping motor that penetrates into the placement frame is fixedly installed inside the fixing frame. The output shaft of the flipping motor is fixedly connected to the flipping frame. A rotating shaft extending into the top of the conveying tray is rotatably installed. A bevel gear is fixedly installed at the bottom of the rotating shaft and at one end of the threaded column. Adjacent bevel gears mesh with each other. A handwheel is fixedly installed at the top of the rotating shaft.

[0010] Preferably, the connecting frame has a U-shaped structure design, and the top of the bearing plate has a groove.

[0011] Preferably, the threaded sleeve has a threaded groove inside that matches the threaded post, and the fixing frame has a U-shaped structure design.

[0012] Preferably, the flipping frame has an L-shaped structure design, and clamping pads are fixedly installed on opposite sides of the left and right sides of the flipping frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The painting device for automotive interior parts features a coordinated design between a material conveying tray and a painting mechanism. The material conveying tray is driven to rotate by a first motor, continuously conveying interior parts to the bottom of the painting box. Combined with the lateral movement structure of the threaded rod and guide rod in the painting mechanism, the nozzle can spray evenly along a preset path. The design of the dual-station material loading and unloading component (two placement frames working alternately) further shortens the loading and unloading time and significantly improves the production cycle.

[0015] The painting device for automotive interior parts uses an electric telescopic rod in conjunction with an adjusting and flipping mechanism. The electric telescopic rod drives the support plate to rise and fall. When the adjusting and flipping mechanism is driven by a threaded column and linked with a bevel gear, the flipping frames on both sides of the interior part clamp it. The flipping motor then drives the flipping frames to flip the clamped interior part. During the flipping, the support plate descends. Combined with the anti-slip design of the clamping pad, this effectively helps the user flip the interior part, avoiding manual contact that could affect the painting effect.

[0026] Example

[0027] like Figures 1-5 As shown, this utility model provides a technical solution: a spraying device for automotive interior parts, including a mounting frame 1, a spraying box 2 fixedly mounted on the top of the mounting frame 1, the mounting frame 1 serving as the basic support structure of the device, the spraying box 2 forming a semi-enclosed spraying environment, reducing the diffusion of paint into the external space and reducing environmental pollution, a first motor 3 fixedly mounted on the bottom of the mounting frame 1, the output shaft of the first motor 3 passing through to the top of the mounting frame 1 and fixedly connected to a conveying tray 4, the first motor 3 driving the conveying tray 4 to rotate, realizing the continuous conveying of interior parts.

[0028] The spraying box 2 has a spraying mechanism 5 that extends through to its outer side and is located above the material conveying tray 4. The spraying mechanism 5 includes a threaded rod 51, which is rotatably mounted between the left and right sides of the inner wall of the spraying box 2. Guide rods 52 located on both sides of the threaded rod 51 are fixedly mounted between the left and right sides of the inner wall of the spraying box 2. A control motor 53 is fixedly mounted on the right side of the spraying box 2. The output shaft of the control motor 53 is fixedly connected to the threaded rod 51. The outer side of the threaded rod 51 is threaded with a sleeve that fits over the two guide rods 52. The threaded block 54 on the side has a nozzle 55 fixedly installed on its top, extending through to its bottom and to the outside of the spray box 2. The nozzle 55 adopts a technical structure known in the prior art. This automotive interior parts spraying device, through the coordinated design of the material conveying tray 4 and the spraying mechanism 5, the material conveying tray 4 is driven to rotate by the first motor 3, which can continuously transport the interior parts to the bottom of the spray box 2. With the lateral movement structure of the threaded rod 51 and the guide rod 52 in the spraying mechanism 5, the nozzle 55 can spray evenly along the preset path.

[0029] The material handling tray 4 has two material feeding and carrying components 6 fixedly installed inside. Each material feeding and carrying component 6 includes a placement frame 61. There are two placement frames 61, which are fixedly installed inside the material handling tray 4. A connecting frame 62 located below the placement frame 61 is fixedly installed at the bottom of the material handling tray 4. The connecting frame 62 has a U-shaped structure design. An electric telescopic rod 63 is fixedly installed at the bottom of the connecting frame 62. The output end of the electric telescopic rod 63 passes through the connecting frame 62 and is fixedly connected to a carrying plate 64 that fits against the inner wall of the placement frame 61. The placement frame 61 and the carrying plate 64 work together to serve as a carrying container for interior parts. The top of the carrying plate 64 has a groove 641. The design of the dual-station material feeding and carrying components 6 (two placement frames 61 work alternately) further shortens the loading and unloading time and significantly improves the production cycle.

[0030] An adjusting and tilting mechanism 7 extending into the material feeding and carrying assembly 6 is movably installed inside the material conveying tray 4. The adjusting and tilting mechanism 7 includes a threaded post 71, which is rotatably installed inside the material conveying tray 4 and located on both sides of the placement frame 61. A threaded sleeve 72 is threadedly installed on the outer side of the threaded post 71. The threaded sleeve 72 has a threaded groove inside that matches the threaded post 71. A fixing frame 73 is fixedly connected to one end of the threaded sleeve 72. The fixing frame 73 has a U-shaped structure design. A tilting motor 74 that penetrates into the placement frame 61 is fixedly installed inside the fixing frame 73. The output shaft of the tilting motor 74 is fixedly connected to a tilting frame 75, which is located in a groove 641. The tilting frame 75 has an L-shaped structure design. Clamping pads 751 are fixedly installed on opposite sides of the left and right tilting frames 75. The tilting frame 75, combined with the anti-slip design of the clamping pads 751, achieves the integration of internal components. The precise flipping and clamping of the interior parts is achieved by rotating a shaft 76 extending into the top of the material tray 4. A bevel gear 77 is fixedly installed at the bottom of the shaft 76 and at one end of the threaded column 71, with adjacent bevel gears 77 meshing with each other. A handwheel 78 is fixedly installed at the top of the shaft 76. This automotive interior parts painting device, through the cooperation of an electric telescopic rod 63 and an adjusting flipping mechanism 7, allows the electric telescopic rod 63 to drive the support plate 64 to rise and fall. When the adjusting flipping mechanism 7 is driven by the threaded column 71 and linked with the bevel gear 77, the flipping frames 75 on both sides of the interior parts clamp them. The flipping motor 74 then drives the flipping frames 75 to flip the clamped interior parts. During flipping, the support plate 64 descends. Combined with the anti-slip design of the clamping pad 751, this effectively helps the user flip the interior parts, avoiding manual contact that could affect the painting effect.

[0031] The working process of this utility model:

[0032] Step 1: The operator places the automotive interior parts to be painted into the placement frame 61 inside the material transport tray 4. The support plate 64 supports the automotive interior parts, completing the initial positioning and support.

[0033] Step 2: Drive the material conveying tray 4 to rotate via the first motor 3, and transport the placement frame 61 carrying the interior parts to the bottom of the spray box 2. At this time, the spraying mechanism 5 starts: control motor 53 drives the threaded rod 51 to rotate, and the threaded rod 51 drives the threaded block 54 to move laterally along the guide rod 52 through the threaded transmission. The nozzle 55 moves synchronously with the threaded block 54 to continuously sweep and spray the surface of the interior parts.

[0034] Step 3: After single-sided spraying is completed, the operator turns the handwheel 78, which drives the threaded column 71 to rotate through the meshing transmission of the rotating shaft 76 and the bevel gear 77. The threaded column 71 drives the threaded sleeve 72 to move laterally through the threaded transmission, so that the fixed frame 73 and the flipping motor 74 are pushed into the placement frame 61, so that the flipping frame 75 clamps and supports the automotive interior parts. At this time, the electric telescopic rod 63 starts and drives the carrier plate 64 to descend to leave flipping space. At this time, the output shaft of the flipping motor 74 drives the flipping frame 75 to rotate and flip. After flipping, the spray nozzle 55 can spray the other side of the interior parts. The device achieves alternating operation through two material feeding and carrying components 6: when one set of placement frames 61 is in the spraying station, the other set can be used for loading, unloading and flipping operations, which significantly shortens non-production time.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
