Description

Technical Field

[0001] This utility model relates to the field of automated coating systems, and in particular to an automated coating system that improves coating efficiency and stability. Background Technology

[0002] An automated coating system refers to a set of equipment systems that use automated technology to coat the surface of products. It typically consists of a feeding system, a conveying system, spraying equipment, drying and curing equipment, and cleaning and exhaust gas treatment equipment. The coordinated operation of these systems enables uniform and precise coating of products of various shapes and materials. The workflow of an automated coating system generally includes several stages: pretreatment, spraying, drying and curing, and post-treatment. The pretreatment stage mainly involves cleaning and treating the product surface to improve coating adhesion; the spraying stage uses automated spray guns to apply a uniform coating to the product; the drying and curing stage uses equipment such as ovens to cure the coating; and the post-treatment stage involves necessary inspection and finishing of the coated product.

[0003] In existing technologies, during the actual use of automated coating systems, after workers hang the parts to be coated on the overhead conveyor line and the parts are transported to the cleaning area, the parts need to be pre-cleaned to remove dust and stains from their surfaces. However, most current cleaning methods rely on manual labor. Manual cleaning requires manual intervention to maintain the stability of the parts on the overhead conveyor line and prevent them from shaking during spraying, which would affect the cleaning operation. Then, a handheld water gun is used to rinse and clean the surface of the parts. This process is cumbersome, time-consuming, labor-intensive, and increases the workload of workers, thereby reducing the coating efficiency and stability of the automated coating system.

[0004] The main objective of this invention is to provide an automated coating system that improves coating efficiency and stability, effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automated coating system for improving coating efficiency and stability includes a suspended conveyor line passing through a coating chamber and a drying chamber. The coating chamber houses a coating robot. A cleaning mechanism is located on the right side of the drying chamber. The cleaning mechanism includes a cleaning chamber, cylinders, clamping plates, a screw, a drive motor, a moving plate, a water spray pipe, nozzles, and a pump. The suspended conveyor line also passes through the cleaning chamber. Cylinders are fixedly connected to both sides of the cleaning chamber. Clamping plates are fixedly connected to the output ends of the cylinders. The screw is movably connected to the bottom surface of a fixed base on one side of the cleaning chamber via a rotating rod at its top. The drive motor is fixedly connected to the top surface of the fixed base and its output end is fixedly connected to the rotating rod. The moving plate is movably connected to the screw via a connecting plate at its rear end. The water spray pipe is fixedly connected to the front end of the moving plate via a U-shaped plate. Several nozzles are fixedly connected to the bottom surface of the water spray pipe. The pump's input end is fixedly connected to a water outlet pipe at the bottom of one side of the cleaning chamber. A connecting pipe connects the pump's output end to the water spray pipe.

[0007] Preferably, a set of symmetrical guide holes are provided on the front and rear side walls of the cleaning chamber, and a cylinder is fixedly installed on the front and rear side walls of the cleaning chamber. A clamping plate is fixedly installed on the output end of the cylinder, and a set of symmetrical guide rods is fixedly installed on the outer side wall of the clamping plate. The guide rods are inserted into the guide holes, and several elastic blocks made of rubber are fixedly installed on the inner side wall of the clamping plate.

[0008] Preferably, a vertical opening is provided on the rear end wall of the cleaning chamber, and a fixing seat is fixedly installed on the top of the rear end wall of the cleaning chamber. The top surface of the fixing seat is provided with an installation hole, and a bearing is fixedly installed in the installation hole.

[0009] Preferably, a rotating rod is fixedly installed at the top end of the screw, and the rotating rod is fixedly installed together with the bearing. The drive motor is fixedly installed on the top surface of the fixed base, and the output end of the drive motor is fixedly installed together with the rotating rod. A connecting plate is fixedly installed on the rear end wall of the moving plate, and the connecting plate passes through the vertical opening. A screw hole is opened on the top surface of the connecting plate, and the connecting plate is threadedly connected to the screw through the screw hole.

[0010] Preferably, the cleaning chamber has a water storage tank inside, and a water outlet pipe connected to the water storage tank is fixedly installed at the bottom of the left side wall of the cleaning chamber.

[0011] Preferably, a set of symmetrical U-shaped plates are fixedly installed on the front wall of the movable plate, and the water spray pipe is fixedly installed on the front wall of the movable plate through the U-shaped plates. Several forward-tilting nozzles are also fixedly installed on the bottom surface of the water spray pipe in a horizontal array. The input end of the pump body is fixedly installed together with the water outlet pipe, and a connecting pipe is fixedly installed between the output end of the pump body and the input end of the water spray pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a cleaning mechanism is installed in the automated coating system. After the parts to be coated are conveyed into the cleaning chamber via a suspended conveyor line, the cylinder drives the output end to push the clamping plate to elastically position and hold the parts through the elastic block. This avoids shaking of the parts during cleaning, thus improving the stability of the parts during cleaning. The pump and drive motor are then activated. The pump draws water from the storage tank for rinsing the parts through the outlet pipe and delivers it to the spray pipe through the connecting pipe. The water is then sprayed onto the surface of the parts through the nozzle to wash away surface dust. Simultaneously, the drive motor drives the output end to rotate the screw via a rotating rod, causing the moving plate to move back and forth along the screw through the screw hole on the top surface of the connecting plate. This, in turn, drives the spray head to complete a comprehensive and rapid cleaning of the painted parts during the up-and-down reciprocating motion. After cleaning, the painted parts are conveyed to the drying chamber via a suspended conveyor line for drying. After drying, they are conveyed to the coating chamber for painting by a coating robot. This achieves the goal of automating the cleaning of painted parts in the automated coating system, thereby improving the coating efficiency and stability of the automated coating system.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 - Figure 4 As shown, an automated coating system for improving coating efficiency and stability includes a suspended conveyor line 1 that passes through a coating chamber 2 and a drying chamber 3. A coating robot 4 is also installed inside the coating chamber 2. A cleaning mechanism 5 is located on the right side of the drying chamber 3. The cleaning mechanism 5 includes a cleaning chamber 6, cylinders 14, clamping plates 15, a screw 18, a drive motor 20, a moving plate 21, a water spray pipe 25, a spray nozzle 26, and a pump body 27. The suspended conveyor line 1 also passes through the cleaning chamber 6, and cylinders 14 are fixedly connected to both sides of the cleaning chamber 6. Clamping plates are fixedly connected to the output ends of the cylinders 14. 15. The screw 18 is movably connected to the bottom surface of the fixed base 11 on one side of the cleaning chamber 6 via the rotating rod 19 at the top end, and the drive motor 20 is fixedly connected to the top surface of the fixed base 11 and is fixedly connected to the rotating rod 19 through the output end. The moving plate 21 is movably connected to the screw 18 through the connecting plate 22 at the rear end, and the water spray pipe 25 is fixedly connected to the front end of the moving plate 21 through the U-shaped plate 24. Several nozzles 26 are also fixedly connected to the bottom surface of the water spray pipe 25, and the input end of the pump body 27 is fixedly connected to the water outlet pipe 8 at the bottom of one side of the cleaning chamber 6. A connecting pipe 28 is also connected between the output end of the pump body 27 and the water spray pipe 25.

[0022] like Figure 2 and Figure 3As shown, a set of symmetrical guide holes 9 are respectively opened on the front and rear side walls of the cleaning chamber 6, and cylinders 14 are fixedly installed on the front and rear side walls of the cleaning chamber 6. A clamping plate 15 is fixedly installed on the output end of the cylinder 14, and a set of symmetrical guide rods 16 are fixedly installed on the outer side wall of the clamping plate 15. The guide rods 16 are inserted into the guide holes 9. Several rubber elastic blocks 17 are also fixedly installed on the inner side wall of the clamping plate 15. When the suspended conveyor line 1 conveys the sprayed part into the cleaning chamber 6, the cylinder 14 will drive the output end to push the clamping plate 15, so that the guide rods 16 on the clamping plate 15 move inward along the guide holes 9 opened on the cleaning chamber 6. The bottom part of the sprayed part is centered, positioned, clamped and fixed between the clamping plates 15 by the elastic blocks 17 on the clamping plate 15. The elastic blocks 17 can avoid damaging the sprayed part by clamping, thereby ensuring the stability of the sprayed part during cleaning and preventing the sprayed part from sliding and affecting the cleaning operation.

[0023] like Figure 2 As shown, a vertical opening 10 is also provided on the rear end wall of the cleaning chamber 6. The vertical opening 10 is used to cooperate with the connecting plate 22 to realize the movement operation. A fixed seat 11 is fixedly installed on the top of the rear end wall of the cleaning chamber 6. A mounting hole 12 is provided on the top surface of the fixed seat 11. A bearing 13 is fixedly installed in the mounting hole 12. The bearing 13 installed in the mounting hole 12 on the top surface of the fixed seat 11 is used to cooperate with the rotating rod 19 to realize the rotation operation.

[0024] like Figure 4 As shown, a rotating rod 19 is fixedly installed at the top of the screw 18, and the rotating rod 19 is inserted and fixedly installed together with the bearing 13. The drive motor 20 is fixedly installed on the top surface of the fixed base 11, and the output end of the drive motor 20 is fixedly installed together with the rotating rod 19. A connecting plate 22 is fixedly installed on the rear end wall of the moving plate 21, and the connecting plate 22 passes through the vertical opening 10. A screw hole 23 is opened on the top surface of the connecting plate 22, and the connecting plate 22 is threadedly connected to the screw 18 through the screw hole 23. When the drive motor 20 is turned on, the output end drives the rotating rod 19 to rotate in the bearing 13. The rotating rod 19 drives the screw 18 to rotate, so that the connecting plate 22 moves up and down in the vertical opening 10 along the screw 18 through the screw hole 23 on the top surface, so as to drive the spray head 26 to complete the rinsing and cleaning of the sprayed parts in the process of up and down reciprocating.

[0025] like Figure 2 As shown, a water storage tank 7 is provided inside the cleaning chamber 6. The water storage tank 7 is used to store the rinsing water and collect the water after rinsing. A water outlet pipe 8 connected to the water storage tank 7 is fixedly installed at the bottom of the left side wall of the cleaning chamber 6. The rinsing water in the water storage tank 7 can be extracted through the water outlet pipe 8.

[0026] like Figure 2 and Figure 4As shown, a set of symmetrical U-shaped plates 24 are fixedly installed on the front wall of the movable plate 21, and the water spray pipe 25 is fixedly installed on the front wall of the movable plate 21 through the U-shaped plates 24. Several forward-tilting nozzles 26 are also fixedly installed on the bottom surface of the water spray pipe 25 in a horizontal array. The input end of the pump body 27 is fixedly installed together with the water outlet pipe 8, and a connecting pipe 28 is fixedly installed between the output end of the pump body 27 and the input end of the water spray pipe 25. When the movable plate 21 moves up and down reciprocally... In this process, since the water spray pipe 25 is fixedly connected to the front end of the moving plate 21 through the U-shaped plate 24, the nozzle 26 installed on the water spray pipe 25 will move up and down synchronously. The pump body 27 will draw water from the water storage tank 7 through the water outlet pipe 8 and then transport the water to the water spray pipe 25 through the connecting pipe 28 installed on the output end. Finally, the water will be sprayed onto the surface of the painted part through the nozzle 26 on the water spray pipe 25 to wash and clean the dust and stains on the surface, so as to achieve the purpose of automated cleaning of the painted part.

[0027] The specific operating procedure and principle of the cleaning mechanism 5 in conjunction with the automated coating system are as follows: When the suspended conveyor line 1 conveys the part to be painted into the cleaning chamber 6, the cylinder 14 drives the output end to push the clamping plate 15 inward. The guide rod 16 installed on the outer wall of the clamping plate 15 moves along the guide hole 9 opened on the cleaning chamber 6, guiding the clamping plate 15 until the bottom end of the part to be painted in the cleaning chamber 6 is centered, positioned, clamped, and fixed between the clamping plates 15. The elastic block 17 installed on the inner wall of the clamping plate 15 provides elastic cushioning during clamping of the part. This mechanism aims to prevent the coated parts from deforming and being damaged under clamping forces. This ensures the stability of the coated parts during cleaning and prevents slippage that could affect the cleaning operation. Then, the pump body 27 and drive motor 20 are turned on. The drive motor 20, mounted on the top surface of the fixed base 11, drives the rotating rod 19 to rotate within the bearing 13 installed in the mounting hole 12 on the top surface of the fixed base 11. The rotating rod 19 then drives the screw 18 to rotate on the bottom surface of the fixed base 11, causing the connecting plate 22 to pass through the screw hole 23 on the top surface along the vertical opening on the rear wall of the cleaning chamber 6 via the screw 18. The moving plate 21 moves up and down within the cleaning chamber 6, while the connecting plate 22 drives the moving plate 21 to move up and down within the cleaning chamber 6. During this movement, because the water spray pipe 25 is fixed to the front wall of the moving plate 21 by a set of symmetrical U-shaped plates 24, the nozzles 26 installed on the water spray pipe 25 will simultaneously perform up and down reciprocating movements. At the same time, the pump body 27 will draw water from the water storage tank 7 in the cleaning chamber 6 through the water outlet pipe 8, and transport the water to the water spray pipe 25 through the connecting pipe 28 installed on the output end. The water is then sprayed onto the surface of the fixed coating part through the nozzles 26 installed on the water spray pipe 25 to treat the coating part. The surface dust and stains are automatically washed and cleaned. The water left over from the cleaning process will flow back into the water storage tank 7 for recycling. Finally, the cleaned sprayed parts will leave the cleaning chamber 6 under the transmission of the suspended conveyor line 1 and enter the drying chamber 3 to dry the residual moisture from the surface cleaning. After drying, they will be conveyed to the coating chamber 2 by the suspended conveyor line 1, where the coating robot 4 will complete the spraying process. This achieves the purpose of automating the cleaning of sprayed parts in the automated coating system, thereby improving the coating efficiency and stability of the automated coating system.
