Description

Technical Field

[0001] This utility model relates to the technical field of raw lacquer finishing equipment, specifically to an automatic raw lacquer spraying machine. Background Technology

[0002] Before the finished product is completed, the surface of handicrafts needs to be painted. Currently, the main method of painting is manual air spraying, which involves first using compressed air to atomize the paint, and then manually spraying the paint onto the surface of the handicraft using a handheld spray gun. Because the atomized paint spreads throughout the painting process, and volatile organic compounds (VOCs) are released on the surface, the working space becomes filled with toxic substances, seriously endangering the health of workers. Therefore, it is necessary to provide a new type of automatic painting device to overcome these problems. Summary of the Invention

[0003] To achieve the above objectives, this utility model provides an automatic raw lacquer spraying machine. The automatic raw lacquer spraying machine has a spraying mechanism based on a coordinate system end effector, which can realize multi-point spraying operations. In addition, J-shaped transparent baffles are set around the frame, which can prevent the atomized spray material from spreading outward while allowing observation of the internal spraying situation and recovery of lost paint. Furthermore, the front and rear baffles have opening and closing functions, which further improves the applicability of the device.

[0004] This utility model is achieved using the following technical solution:

[0005] An automatic lacquer spraying machine includes a carrier, a support frame, a recovery baffle structure, an end effector, and a spraying module. The carrier includes a vehicle body, a steering mechanism, and tires. The vehicle body is symmetrically distributed on the left and right sides of the machine. The steering mechanism is directly powered by a motor, allowing each tire to rotate independently radially, enabling functions such as steering or turning on the spot. The tires are directly powered by hub motors.

[0006] Furthermore, the bracket is used to connect the vehicles on both sides.

[0007] Furthermore, the recycling baffle structure includes a top plate, a front baffle, a rear baffle, a left baffle, a right baffle, a linkage mechanism, a small recycling box, and a large recycling box. The top plate is located above the support frame. The front baffle and the rear baffle are fixed to the top plate via the linkage mechanism. The left baffle and the right baffle are fixed to the left and right sides of the support frame. The small recycling box is fixed in the arc-shaped structure at the rear of the front baffle and the rear baffle. The large recycling box is fixed in the arc-shaped structure at the rear of the left baffle and the right baffle.

[0008] Furthermore, the linkage mechanism includes a telescopic motor and a connecting rod. The telescopic motor is fixed above the top plate, and the connecting rod is connected to the telescopic motor and the top plate via a hinge.

[0009] Furthermore, the end effector includes a first slide rail, a second slide rail, a fixed frame, and a reciprocating mechanism. The first slide rail is fixed below the top plate and is vertically connected to the second slide rail through the reciprocating mechanism. The fixed frame is connected to the second slide rail through the reciprocating mechanism.

[0010] Furthermore, the reciprocating mechanism includes a reciprocating lead screw and a motor. The reciprocating lead screw is connected to the slide rail via bearings, and the output shaft end of the motor is fixedly connected to the reciprocating lead screw.

[0011] Furthermore, the spraying module includes a spray head, an air compressor, a diaphragm pump, a paint bucket, an air pipe, a material delivery pipe, and a return pipe. The spray head is fixedly connected to the upper end of the mounting frame. The air compressor is fixed above the carrier. The diaphragm pump and the paint bucket are fixed above the other side of the carrier. The air pipe is used to connect the air compressor and the diaphragm pump, and also connects the air compressor and the spray head. The material delivery pipe and the air pipe return pipe are used to connect the air pipe paint bucket and the air pipe diaphragm pump. The diaphragm pump is connected to the air pipe spray head through the air pipe material delivery pipe.

[0012] This utility model has the following beneficial effects:

[0013] (1) By setting up a carrier, frame, end effector and spraying module, the painting of handicrafts is automated. The structure is simple, the operation is convenient, the painting efficiency is improved and the labor demand is reduced.

[0014] (2) By designing the top plate, front baffle, rear baffle, left baffle and right baffle, the diffusion of atomized paint during the spraying process is greatly reduced, and the paint lost during the spraying process can be effectively collected. At the same time, the front and rear baffles are openable and closable mechanisms, which improves the applicability of the device, saves costs, reduces labor intensity and reduces environmental pollution.

[0015] (3) By designing the carrier and end effector, the nozzle can move freely in the vertical plane and the frame can rotate freely, enabling multi-angle spraying of handicrafts during the processing and improving the painting efficiency. Attached Figure Description

[0021] like Figure 1 As shown, this embodiment provides an automatic lacquer spraying machine including a carrier 1, a support 2, a recovery baffle structure 3, an end effector 4, and a spraying module 5. The carrier 1 includes a vehicle body 11, a steering mechanism 12, and tires 13. The vehicle body 11 is symmetrically distributed on the left and right sides of the machine and fixed by the support 2. The steering mechanism 12 is located below the vehicle body 11 and is powered by a motor inside the vehicle body 11. The tires 13 are fixed between the two side plates of the steering mechanism 12 and are powered by a hub motor.

[0022] like Figure 3As shown, the recycling baffle structure 3 includes a top plate 31, a front baffle 32, a rear baffle 33, a left baffle 34, a right baffle 35, a linkage mechanism 36, a small recycling box 37, and a large recycling box 38. The top plate 31 is fixed above the support 2. The front baffle 32 and the rear baffle 33 are fixed above the top plate 31 via the linkage mechanism 36. The left baffle 34 is fixed to the left side of the support 2, and the right baffle 35 is fixed to the right side of the support 2. The small recycling box 37 is fixed in the lower grooves of the front baffle 32 and the rear baffle 33, respectively. The large recycling box 38 is fixed in the lower grooves of the left baffle 34 and the right baffle 35, respectively. During the spraying process, paint lost in the air adheres to the baffles. After adhering to a certain extent, the paint flows downwards into the recycling box. The linkage mechanism 36 includes a telescopic motor 361 and a connecting rod 362. The telescopic motor 361 is fixed above the top plate 31. One end of the connecting rod 362 is hinged to the shaft end of the telescopic motor 361, and the other end is connected to the front baffle 32 and the rear baffle 33. The middle part is hinged to the top plate 31. When the telescopic motor 361 extends or retracts, its shaft end drives the connecting rod 362 to rotate circumferentially at the hinge of the top plate 31, so that the front baffle 32 and the rear baffle 33 can open and close.

[0023] like Figure 4 As shown, the end effector 4 includes a first slide rail 41, a second slide rail 42, a fixing frame 43, and a reciprocating mechanism 44. The first slide rail 41 is fixed below the top plate 31. The upper protruding part of the second slide rail 42 is provided with a nut hole, so that the second slide rail 42 can cooperate with the reciprocating mechanism 44 in the first slide rail 41. The fixing frame 43 is also provided with a nut hole, so that the fixing frame 43 and the second slide rail 42 can cooperate. The reciprocating mechanism 44 includes a reciprocating screw 441 and a motor 442. The reciprocating screw 441 is connected to the first slide rail 41 and the second slide rail 42 respectively through bearings. The output shaft end of the motor 442 is fixedly connected to the reciprocating screw 441. The lead screw is powered by a motor to rotate. At this time, the second slide rail 42 will move left and right along the first slide rail 41 due to the lead screw and nut. Similarly, the fixed frame will also move up and down along the second slide rail 42 due to the lead screw and nut, so that the fixed frame 43 can move freely in the vertical plane.

[0024] like Figure 4As shown, the spraying module 5 includes a spray nozzle 51, an air compressor 52, a diaphragm pump 53, a paint bucket 54, an air pipe 55, a material delivery pipe 56, and a return pipe 57. The spray nozzle 51 is fixed to the front end of the mounting bracket 43. The air compressor 52 is placed above the vehicle body 11. The diaphragm pump 53 and the paint bucket 54 are located above the other side of the vehicle body 11. The air pipe 55 connects the air compressor 52 and the diaphragm pump 53, and also connects the air compressor 52 and the spray nozzle 51. The material delivery pipe 56 and the return pipe 57 connect the paint bucket 54 and the diaphragm pump 53. The diaphragm pump 53 is connected to the spray nozzle 51 through the material delivery pipe 56. The air compressor 52 delivers high-pressure air to the diaphragm pump 53 through the air pipe 55, so that the paint flows from the paint bucket 54 through the feed pipe 56 through the diaphragm pump 53 and is finally pumped into the nozzle 51. Excess paint flows back to the paint bucket 54 through the return pipe 57. At the same time, the air compressor 52 delivers high-pressure air to the nozzle 51 through the air pipe 55 again. The high-pressure airflow atomizes the paint from the nozzle 51 and sprays it out, achieving the purpose of painting.
