[0049] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0050] like Figure 1-6 As shown, a paint dripping device includes:

[0051] 100 machines;

[0052] Six coating station components 200 are spaced apart on the machine base 100 along the X-axis direction;

[0053] Three heating devices 300 are slidably mounted on the machine base 100;

[0054] Six waste liquid collection devices 400 are installed on the machine base 100 and are located below the corresponding coating station components 200.

[0055] Waste liquid collection device 400 includes:

[0056] The receiving tray 410 is located directly below the coating station component 200;

[0057] Twelve waste liquid collection tanks 420 are detachably installed below the receiving tray 410. The bottom of the receiving tray 410 is provided with a discharge port 411, which is connected to the inlet of the waste liquid collection tank 420.

[0058] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, during operation, the coating station components 200 are spaced apart on the machine base 100 along the X-axis, allowing multiple stations to perform coating operations simultaneously without interference. The heating device 300 is slidably mounted on the machine base 100 and can be moved and shared among the coating station components 200. The waste liquid collection device 400 is located below the corresponding coating station component 200, collecting the waste liquid generated during the coating process through the receiving tray 410 and flowing into the waste liquid collection tank 420 through the discharge port 411 for centralized collection. This structural configuration solves the technical problems of large equipment footprint, low heating device utilization, and difficult waste liquid treatment in the prior art, achieving a compact layout of equipment and reasonable allocation of resources, thereby improving production efficiency and reducing equipment costs.

[0059] Specifically, such as Figure 1-4 As shown, the waste liquid collection device 400 also includes:

[0060] Guide column 430, the guide column 430 is vertically fixed below the machine base 100;

[0061] Adjustable slider 440 is slidably sleeved on guide column 430;

[0062] The liquid level sensor 450 is mounted on the guide column 430 via an adjustable slider 440, with the detection end of the liquid level sensor 450 facing the inside of the waste liquid collection tank 420.

[0063] The adjustable slider 440 is equipped with a handle screw 461, and the adjustable slider 440 is adapted to move the liquid level sensor 450 in the vertical direction when the handle screw 461 is loosened.

[0064] Specifically, such as Figure 1-3 As shown, the waste liquid collection device 400 includes two waste liquid collection tanks 420, which are arranged side by side.

[0065] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the waste liquid collection device 400 adjusts the height of the liquid level sensor 450 through the cooperation of the guide column 430 and the adjustable slider 440. The guide column 430 is vertically fixed below the machine base 100 to provide guidance and support for the adjustable slider 440. The adjustable slider 440 is slidably sleeved on the guide column 430 and can slide along the axial direction of the guide column 430. The liquid level sensor 450 is installed on the guide column 430 through the adjustable slider 440 with the detection end facing the inside of the waste liquid collection tank 420. The handle screw 461 is set on the adjustable slider 440 to fix the position of the liquid level sensor 450. When the operator loosens the handle screw 461, the adjustable slider 440 can drive the liquid level sensor 450 to move vertically to a suitable height and then lock it again, thereby adapting to waste liquid collection tanks 420 of different heights and ensuring the accuracy of liquid level detection.

[0066] Two waste liquid collection tanks 420 are arranged side by side below the receiving tray 410. One waste liquid collection tank 420 is connected to the discharge port 411 of the receiving tray 410 to collect waste liquid, while the other waste liquid collection tank 420 serves as a spare tank. When the waste liquid collection tank 420 in use is full, the operator can remove it and move the spare waste liquid collection tank 420 below the discharge port 411 to continue collecting waste liquid, achieving continuous operation without stopping the machine to wait for waste liquid treatment. In some embodiments, the number of waste liquid collection tanks 420 is not limited to two; more tanks can be set according to specific production needs and waste liquid generation.

[0067] In this embodiment, the waste liquid collection tank 420 is a 10L transparent plastic tank.

[0068] Specifically, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the coating station assembly 200 includes:

[0069] Swing bracket 210, swing bracket 210 is mounted on machine base 100;

[0070] The clamping mechanism 220 is mounted on the swing bracket 210 and has a clamping part suitable for clamping the workpiece.

[0071] The coating mechanism 230 is mounted on the swing bracket 210. The coating mechanism 230 includes a first coating component 231 and a second coating component 232. The first coating component 231 and the second coating component 232 are adapted to be located on both sides of the clamping part for coating during coating.

[0072] Specifically, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the swing bracket 210 includes:

[0073] The upright frame 211 is fixedly installed on the machine base 100;

[0074] The upper support 212 is hinged to the upright 211, and the lower part of the upper support 212 is provided with a second waist groove.

[0075] The swing drive mechanism 214 is mounted on the machine base 100. The swing drive mechanism 214 is provided with a push rod 215. The end of the push rod 215 is provided with a first waist groove, and the first waist groove is hinged to a second waist groove.

[0076] The clamping mechanism 220 and the coating mechanism 230 are mounted on the upper support 212, and the swing drive mechanism 214 is adapted to drive the upper support 212 to swing around the hinge of the upright 211 via the push rod 215.

[0077] In this embodiment, as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the swing bracket 210 achieves its overall swing function through the hinged connection between the upright frame 211 and the upper bracket 212. The upper bracket 212 is hinged to the upright frame 211 and can swing around the hinge point. The lower part of the upper bracket 212 is provided with a second waist groove, which is hinged to the first waist groove at the end of the push rod 215 of the swing drive mechanism 214. The swing drive mechanism 214 is mounted on the machine base 100 and drives the upper bracket 212 to swing around the hinge point of the upright frame 211 through the telescopic movement of the push rod 215. This allows the clamping mechanism 220 and the coating mechanism 230 mounted on the upper bracket 212 to be adjusted to different coating angles. In this embodiment, the swing drive mechanism 214 is a linear motor drive module; in other embodiments, it can also be a cylinder or an electric push rod.

[0078] Both the clamping mechanism 220 and the coating mechanism 230 are mounted on the upper support 212 of the swing bracket 210 to achieve synchronous swinging. The clamping mechanism 220 is provided with a clamping part for fixing and clamping the workpiece to be coated. The coating mechanism 230 includes a first coating component 231 and a second coating component 232, which are respectively arranged on both sides of the clamping part. When the swing bracket 210 swings to a suitable angle, the first coating component 231 and the second coating component 232 can simultaneously coat both ends of the workpiece. By adjusting the swing angle, the coating direction and coverage area can be changed to adapt to the coating requirements of workpieces with different shapes. In this embodiment, the swing angle is ±30 degrees.

[0079] Specifically, such as Figure 2 , Figure 3 and Figure 6 As shown, the clamping mechanism 220 includes:

[0080] An electrical slip ring 221 is provided with a fixed ring and a rotating ring, and the fixed ring is mounted on the swing bracket 210.

[0081] Three-jaw cylinder 222, the three-jaw cylinder 222 is mounted on the rotating ring of the electric slip ring 221;

[0082] A rotary servo motor 223 is connected to a three-jaw cylinder 222 for transmission. The rotary servo motor 223 is suitable for driving the three-jaw cylinder 222 and the workpiece being clamped to rotate.

[0083] The clamping part is located on the three-jaw cylinder 222.

[0084] In this embodiment, as Figure 2 , Figure 3 and Figure 6 As shown, the electric slip ring 221 is fixed on the swing bracket 210 and remains stationary. The rotating ring is coaxial with the fixed ring and can rotate relative to the fixed ring, thereby providing an air source for the three-jaw cylinder 222 mounted on the rotating ring.

[0085] A three-jaw cylinder 222 is mounted on the rotating ring of an electric slip ring 221 and has a clamping part for clamping the workpiece. When an air source is supplied to the three-jaw cylinder 222, it expands outward to clamp and fix the workpiece. A rotary servo motor 223 is driven by the connecting shaft of the three-jaw cylinder 222. Specifically, the drive wheel can be set on the rotary servo motor 223, and the driven wheel can be set on the connecting shaft of the three-jaw cylinder 222. The drive wheel and the driven wheel are connected by a transmission belt. The output shaft of the rotary servo motor 223 drives the three-jaw cylinder 222 and the clamped workpiece to rotate around the clamping axis, realizing the angle adjustment and full-circumference coating of the workpiece during the coating process. The rotary servo motor 223 is fixed on the upper bracket 212.

[0086] The specific model of the electrical slip ring 221 in this embodiment is the Mofron MAPH200 electrical slip ring.

[0087] Specifically, such as Figure 1-2 As shown, the heating device 300 includes:

[0088] A linear drive module 310 is mounted on a machine base 100. The linear drive module 310 is provided with a slide 311 and is adapted to drive the slide 311 to move along the X-axis.

[0089] The forward and backward mechanism 320 is mounted on the slide 311 of the linear drive module 310. The forward and backward mechanism 320 is provided with a moving plate 321 and is adapted to drive the moving plate 321 to move along the Y-axis.

[0090] Heating coil 330 is mounted on the moving plate 321 of the forward and backward mechanism 320;

[0091] The advancing and retreating mechanism 320 drives the heating coil 330 to advance and retreat along the Y-axis.

[0092] Specifically, such as Figure 1-2 As shown, the paint dripping equipment also includes an operation cabinet 500, which has an operation panel connected to the clamping mechanism 220, the coating mechanism 230, and the heating device 300.

[0093] In this embodiment, as Figure 1-2 As shown, the linear drive module 310 achieves the switching of the heating device 300 between different coating station components 200 through the X-axis movement of the slide 311. The linear drive module 310 is mounted on the machine base 100 and is equipped with a guide rail and a transmission mechanism. The slide 311 is slidably mounted on the guide rail and is driven to move along the X-axis direction by the transmission mechanism, thereby enabling the forward and backward mechanism 320 and the heating coil 330 mounted on the slide 311 to move between the various coating station components 200 and provide heating services for the workpieces at different stations. In this embodiment, the transmission mechanism of the linear drive module 310 is a servo motor in conjunction with a ball screw; in other embodiments, it can also be driven by a linear motor or a cylinder.

[0094] The advancing / retreating mechanism 320 is mounted on the slide 311 of the linear drive module 310. The advancing / retreating motion of the heating coil 330 is controlled by the Y-axis movement of the moving plate 321. The advancing / retreating mechanism 320 includes a moving plate 321 that slides along the Y-axis. The mechanism includes a drive source. When the drive source drives the moving plate 321 forward along the Y-axis, it brings the heating coil 330 mounted on the moving plate 321 closer to the workpiece for heating. When the drive source drives the moving plate 321 backward, the heating coil 330 moves away from the workpiece to avoid interference with the coating process. In this embodiment, the drive source of the advancing / retreating mechanism 320 is a linear motor; in other embodiments, it can also be an electric push rod or a cylinder.

[0095] In addition, the coating station assembly 200 also includes a temperature detection sensor, which is mounted on the swing bracket 210 and faces the clamping part of the clamping mechanism 220. The temperature detection sensor is used to detect the surface temperature of the clamped workpiece. When the workpiece temperature reaches the preset coating temperature, the coating operation is started. When the workpiece temperature is not up to standard, the heating device 300 moves to the station and starts the heating coil 330 to supplement the heating of the workpiece. The workpiece detection sensor is mounted on the upper bracket 212 facing the clamping mechanism 220 and is used to detect whether the workpiece is clamped in place. The equipment will only perform subsequent temperature detection and coating operations when the workpiece detection sensor detects the presence of the workpiece. In this embodiment, the temperature detection sensor is an infrared temperature sensor, and the workpiece detection sensor is a photoelectric sensor.
