Description

Technical Field

[0001] This utility model belongs to the technical field of spraying devices, and in particular relates to a spraying device for metal rubber joints. Background Technology

[0002] Metal-rubber joints are structural components made by bonding metal parts and rubber through processes such as vulcanization. They require painting before use, but painting metal-rubber joints is relatively cumbersome, requiring suspended painting. When painting a single joint suspended, the spray gun can be manually operated to evenly coat the metal-rubber joint around its circumference. However, in automated painting processes, the suspended metal-rubber joint needs to be circulated and transported. When the joint enters the painting station, the equipment can only paint one side, requiring rotation during the painting process for effective coating. However, rotating the joint during transport is relatively difficult; therefore, painting is generally done manually with a spray gun, as robotic arms cannot be used, resulting in low painting efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a painting device for metal rubber nodes. A series of painting parts are transported in a cyclic manner via a transport track. The painting parts transport the metal rubber nodes into the spray box for mechanized spraying. The spraying process can also rotate the metal rubber nodes for spraying, which solves the problems of the inability of the metal rubber nodes to rotate and the low spraying efficiency in existing mechanized spraying.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a painting device for metal rubber joints, comprising a transport track, a painting component hanger, a hanger drive assembly, a painting box, and a painting device. The transport track includes an outer track and an inner track, both of which are in the same horizontal plane and form a closed track. The cross-sections of the outer track and the inner track are symmetrical. The two ends of the painting component hanger are slidably engaged on the outer track and the inner track. The painting component hangers are connected by connecting rods. The transport track is provided with multiple hanger drive assemblies that drive the painting component hangers to move on the transport track. A section of the transport track passes through the left and right side walls of the painting box. A painting device for spraying paint into the painting box is installed on the front side wall of the painting box.

[0006] The present invention is further configured such that the transport track includes two semicircular tracks and two straight tracks, the ends of the two semicircular tracks respectively docking with the two straight tracks, and one of the straight tracks is inserted into the spray box.

[0007] The present invention is further configured such that the spraying component hanger includes two slide plates, a connecting column, a roller column, a connecting rod column, a push rod, and a hanging column. The two slide plates are connected by connecting columns near the four corners. The two slide plates are symmetrically provided with roller columns on both sides that are connected to the outer and inner tracks. The two slide plates are symmetrically provided with connecting rod columns on the other two sides. A push column is fixed at the center of the upper slide plate, and a downward-facing hanging column is rotatably installed at the center of the lower slide plate.

[0008] The two slide plates are respectively locked onto the top and bottom walls of the outer and inner tracks at the positions where they meet the outer and inner tracks. A limiting rail is provided at the middle position of the inner side of the outer and inner tracks. Supporting edges are provided at the top and bottom of the outer and inner tracks. The concave roller on the roller column is locked onto the edge of the limiting rail. The connecting rods between adjacent spray painting parts are connected by connecting rods.

[0009] The present invention is further configured such that a gear disk is provided on the hanging column, a hanging hole is provided at the bottom of the hanging column, a gear disk push rod is provided on the outer side of the outer track inside the spray box, the gear disk push rod is an L-shaped rod, and a rack belt is provided on the inner side of the horizontal rod of the L-shaped rod, the rack belt meshing with the gear disk.

[0010] The present invention is further configured such that a water tank is provided inside the spray box, and a water spray pipe for spraying downward along the wall is provided on the top of the upward side wall of the water tank.

[0011] The present invention is further configured such that the hanging component driving assembly includes an inverted U-shaped frame and a push wheel.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 This utility model is a painting device for metal rubber joints, including a transport track 3, a painting part hanger 4, a hanger drive assembly 5, a painting box 1, and a painting device 2. The transport track 3 includes an outer track and an inner track, and the two tracks are in the same horizontal plane, forming a closed track. The cross-sections of the outer track and the inner track are symmetrical. The two ends of the painting part hanger 4 are slidably locked on the outer track and the inner track. The painting part hangers 4 are connected by connecting rods. The transport track 3 is provided with multiple hanger drive assemblies 5 for driving the painting part hangers 4 to move on the transport track 3. A section of the transport track 3 passes through the left and right side walls of the painting box 1. The painting device 2 for spraying paint into the painting box 1 is installed on the front side wall of the painting box 1.

[0028] During the spraying process, multiple hanger drive components 5 synchronously drive the displacement of their respective spraying part hangers 4, ensuring that the spraying part hangers 4, connected in a series, have driving force at each node position, thus guaranteeing smooth operation of the spraying part hangers 4. Each spraying part hanger 4 has a metal rubber node attached to its bottom, with gaps between the metal rubber nodes. The metal rubber nodes are slowly transported into the spraying box 1. When they reach the spraying position of the spraying equipment 2, the spraying equipment 2 will automatically identify them (using a metal part sensor or distance sensor) and begin spraying. During the spraying process, the metal rubber nodes rotate. After spraying, the hangers are removed from the spraying box 1 and allowed to air dry naturally until the metal rubber nodes are replaced.

[0029] The outer and inner tracks are positioned to support the two sides of the spray painting component 4, allowing the spray painting component 4 to slide on the outer and inner tracks.

[0030] The transport track 3 includes two semicircular tracks and two straight tracks. The ends of the two semicircular tracks are respectively connected to the two straight tracks, and one of the straight tracks is inserted into the spray box 1.

[0031] The straight track is for easy insertion into the spray box 1 and for replacing the metal rubber nodes on the outside, while the semi-circular track is for turning.

[0032] The spraying component hanger 4 includes two slide plates 41, connecting columns 42, roller columns 43, connecting rod columns 44, push rods 45, and hanger columns 461. The two slide plates 41 are connected by connecting columns 42 near the four corners. The two slide plates 41 are symmetrically provided with roller columns 43 on both sides that meet the outer and inner tracks. The two slide plates 41 are symmetrically provided with connecting rod columns 44 on the other two sides. The push column 45 is fixed at the center of the upper slide plate 41, and the hanger column 461 is rotatably installed at the center of the lower slide plate 41.

[0033] The two slide plates 41 are respectively locked onto the top and bottom walls of the outer and inner tracks at the positions where they meet the outer and inner tracks. A limiting rail 32 is provided at the middle position of the inner side of the outer and inner tracks. Supporting edges 31 are provided at the top and bottom of the outer and inner tracks. The concave roller 431 on the roller column is locked onto the side of the limiting rail 32. The connecting rods 44 between adjacent spray painting parts 4 are connected by connecting rods 40.

[0034] like Figure 2-4 As shown, the upper slide plate 41 rests on the support edges 31 at the top of the outer and inner tracks on both sides, while the lower slide plate 41 is limited by the support edges 31 at the bottom of the outer and inner tracks on both sides. Figure 4 (As shown). To facilitate a smooth sliding process, the concave roller 431 can slide on the side of the limiting rail 32, thus reducing friction with the side of the limiting rail 32.

[0035] The connecting rod post 44 is used to install the connecting rod 40. The two ends of the connecting rod 40 are rotatably sleeved on the middle position of the connecting rod post 44. The connecting rod post 44 can play a pulling role, and the connecting rod 40 can rotate on the connecting rod post 44 when turning.

[0036] like Figure 2 Push wheel 52 pushes push column 45 to move one by one. Hanging column 461 is used to hang hooks, and then the metal rubber node is hung on the hook.

[0037] The hanging post 461 is provided with a gear disk 46, and the hanging post 461 is provided with a hanging hole at the bottom end. The outer side of the outer track inside the spray box 1 is provided with a gear disk push rod 6. The gear disk push rod 6 is an L-shaped rod 61. The inner side of the horizontal rod of the L-shaped rod 61 is provided with a rack belt 62, and the rack belt 62 meshes with the gear disk 46.

[0038] When the gear disk 46 reaches the position of the rack belt 62, it will automatically mesh. The gear disk 46 will be driven to rotate along the rack belt 62. When it rotates, the metal rubber node will also rotate accordingly, so that the metal rubber node rotates during spraying, thereby achieving full spraying.

[0039] The spray box 1 contains a water tank 13, and a water spray pipe 12 is installed on the top of the upward-facing side wall of the water tank 13, spraying downwards along the wall. The sprayed water flows down along the inner side wall, and the paint that is not sprayed onto the metal rubber joints is absorbed by the water and flows down, preventing the atomized paint from spreading. One end of the water spray pipe 12 is sealed, and the other end is connected to a water supply hose. The water tank 13 discharges outwards at the same speed as the spraying speed.

[0040] The hanging component drive assembly 5 includes an inverted U-shaped frame 51 and a push wheel 52. The lower end of the inverted U-shaped frame 51 is fixed on the outer wall of the outer track and the inner track 3. The two ends of the push wheel 52 are rotatably mounted on the two side walls of the inverted U-shaped frame 51. The push wheel 52 is driven to rotate by a servo motor. Multiple push plates are evenly distributed on the push wheel 52.

[0041] The push wheel 52 rotates on the inverted frame 51, as... Figure 2 The pusher 52 has a gear-like push plate around its circumference. The push plate is relatively long and can push the push column 45 to move one by one.

[0042] The spraying equipment 2 has a robotic arm and a spray gun mounted on the side wall facing the inside of the spray box 1, with the spray gun mounted on the operating end of the robotic arm. The robotic arm and spray gun are existing technologies, and robotic arm-operated spraying is used in many places, such as automotive spraying; the specific structure is not described here. A row of 3-5 robotic arms and spray guns can be arranged in combination to perform repeated multi-layer spraying.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
