Description

Technical Field

[0001] This invention relates to the field of lampshade conveying technology, specifically to a conveying device and its usage method for lampshade processing. Background Technology

[0002] As a key component for light distribution and decoration, lampshades have increasingly higher requirements for surface coating quality. Lampshade spraying lines typically need to complete multiple processes such as inner surface spraying, outer surface spraying, leveling and drying, and paint mist recovery. In lampshade spraying lines, the transport device plays the core role of delivering lampshades to the spraying station in sequence and cooperating to complete the inner and outer surface spraying operations.

[0003] A conveying device for processing street lamp covers is disclosed in existing patent publication number CN202410766437.X, comprising: a first side plate, placed on the ground by supporting legs; a second side plate disposed to the right of the first side plate; shafts rotatably disposed between the front and rear portions of the first and second side plates; sprockets fixedly sleeved on both sides of the two shafts; chains meshing between the two sprockets on the left and the two sprockets on the right; a servo motor fixedly disposed at the front right side of the second side plate; the output end of the servo motor passing through the second side plate and fixedly connected to the right end of the front shaft; a first rack fixedly disposed at both the front and rear ends of the upper right side of the first side plate; and a second rack fixedly disposed at the front end of the lower left side of the second side plate. A first protruding bracket mechanism is fixedly installed at the rear end of the right bottom of the first side plate, and a second protruding bracket mechanism is fixedly installed at the rear end of the left bottom of the second side plate. The first and second protruding bracket mechanisms have the same structure and are symmetrical. A surface defect detection mechanism is installed between the upper rear parts of the first and second side plates. The bottom of the surface defect detection mechanism is fixedly connected to the rear right part of the second side plate. It can only perform a single dust removal operation during transportation and cannot actively intervene to ensure the coating quality during transportation. During transportation, the paint mist sprayed can easily drift into the inside of the lampshade and contaminate the intact inner coating, affecting the product qualification rate. This forces the coating cycle to be extended. In addition, the multiple transportation and transfer of the lampshade between different workstations increases the positioning error and the risk of bumps and knocks. Some improvements are needed. Summary of the Invention

[0009] The present invention further illustrates that two sets of second hoses are slidably installed at the other end of the top of the work box, and two sets of third hoses and two sets of fourth hoses are respectively slidably installed on both sides of the top of the work box. The structures of the two sets of second hoses, two sets of third hoses and two sets of fourth hoses are the same as the structures of the two sets of first hoses.

[0010] The present invention further illustrates that the first electric valve is fixedly installed inside the first conveying pipe at one end near the working box, and the second electric valve is fixedly installed inside the second conveying pipe at one end near the working box.

[0011] The present invention further illustrates that the third electric valve is fixedly installed inside the first conveying pipe near one end of the two sets of first hoses, and the fourth electric valve is fixedly installed inside the first conveying pipe near one end of the two sets of third hoses. The fifth electric valve is fixedly installed inside the second conveying pipe near one end of the two sets of second hoses, and the sixth electric valve is fixedly installed inside the second conveying pipe near one end of the two sets of fourth hoses. The interior of the lampshade spraying workshop is hollow.

[0012] The present invention further illustrates that a transportation control system is provided in the lampshade spraying workshop. The transportation control system includes a data acquisition module and a control module. The data acquisition module and the control module are interconnected by signals. The data acquisition module includes an image recognition submodule and an analysis submodule. The image recognition submodule is electrically connected to the first camera, the second camera, and the third camera. The control module includes a conveying control submodule and a conveying spraying submodule. The conveying control submodule is electrically connected to a motor, an electric telescopic frame, a transport robot, a workshop pipeline connection box, an electric telescopic rod, and several sets of gripper assemblies. The conveying spraying submodule is electrically connected to a first spraying robot, a second spraying robot, and six sets of electric valves.

[0013] Includes the following steps: Step 1: When the lampshade painting line needs to be processed, the staff first manually places the lampshade on the workshop conveyor line in the lampshade feeding room and pushes it to one side of the transport robot. Step 2: Start the spraying and transport components to grab and transport the lampshade; Step 3: After the grabbing and conveying is completed, start the spraying assembly to perform spraying processing on the inside and outside of the lamp cover.

[0014] Step three also includes the following specific operational steps: Step 3-a: During the spraying operation of the first spraying robot, the transport control system controls the dust removal operation. Step 3-b: During the spraying operation of the second spraying robot, the transport control system controls the ventilation operation.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention adjusts the position of the lampshade before spraying so that it is placed in an inclined position, and pre-adjusts the tilt posture of the lampshade to ensure that the workpiece posture is consistent during the subsequent spraying process inside the lampshade, avoiding uneven spraying or spraying dead corners, which helps to ensure the uniformity and consistency of the final coating quality. The lampshade is sprayed inside and out during transportation. After the inside of the lampshade is sprayed, a second inspection is carried out to ensure that there are no dead corners in the spraying. The tilt angle of the lampshade is adjusted so that the liquid paint sprayed inside the lampshade can flow level by gravity. At the same time, it is easy for the liquid paint to flow out during the second spraying. It prevents the liquid paint from accumulating on the bottom edge of the inside of the lampshade, which would cause uneven spraying thickness and affect subsequent production processing. After the outside of the lampshade is sprayed, a second inspection is carried out and the spraying amount is increased to touch up the defective areas. By simultaneously spraying the inside of the lampshade and drawing the generated paint mist into the workshop dust collection device, zero-time-difference synchronization of spraying and mist removal is achieved. This effectively avoids coating particle and sagging defects caused by secondary settling of paint mist, ensuring the smoothness and uniformity of the spraying. Secondly, during the spraying operation, the second hose is controlled to pre-clean the lampshade to be sprayed, which has been placed on another conveyor rack, in advance to remove floating dust and moisture, preventing quality problems such as reduced adhesion of the coating film, thereby improving the product qualification rate. By simultaneously spraying the exterior of the lampshade and sealing it with a third hose connected to a third conveyor, the liquid paint sprayed inside the lampshade is rapidly dried, accelerating the curing process and preventing sagging or wrinkling caused by undried internal coatings. At the same time, the continuously blowing airflow forms an outward air barrier around the inside of the lampshade, effectively preventing paint mist generated during external spraying from drifting into the lampshade. This avoids secondary contamination of the already sprayed surface or changes in coating uniformity, ensuring the independent quality of the inner and outer coatings. Furthermore, it allows for secondary drying pretreatment of the lampshade on another conveyor, further removing residual moisture and providing a drier, cleaner substrate surface for subsequent spraying, effectively preventing defects such as coating bubbles and reduced adhesion caused by moisture.

The rotating conveyor table 31 is detachably mounted on the work box 21. The rotating conveyor table 31 is connected to the rotating shaft of the motor 213. The first conveyor frame 32, the second conveyor frame 33, the third conveyor frame 34, and the fourth conveyor frame 35 are arranged in a circular pattern on the rotating conveyor table 31. Each of the four conveyor frames has a built-in conveying pipe (not shown in the figure). The four conveyor frames have the same structure. Several sets of gripper assemblies 321 are arranged in an array on the four conveyor frames. Four sets of pipe connection seats 326 are circumferentially mounted on the rotating conveyor table 31, corresponding to the positions of the four sets of conveyor frames. One end of each of the two sets of fourth conveyor pipes 327 is connected to the pipe connection seat 326, and the other end is connected to the built-in conveyor pipes of the four sets of conveyor frames respectively. The pipe connection ports of the four sets of pipe connection seats 326 are all made of metal. The gripper assembly 321 includes an electric telescopic rod 322, an anti-slip bracket 323, a cleaning hole 324, and a third conveying pipe 325. The electric telescopic rod 322 is arrayed and mounted on the first conveying frame 32 for lifting operations. The anti-slip bracket 323 is fixedly mounted on one end of the electric telescopic rod 322 for fixing the lampshade. The cleaning hole 324 is arrayed on one side of the anti-slip bracket 323 for conveying and processing the lampshade. One end of the third conveying pipe 325 is connected to the cleaning hole 324, and the other end is connected to the built-in pipe of the first conveying frame 32. The lampshade painting workshop 1 is equipped with a transportation control system, which includes a data acquisition module and a control module. The data acquisition module and the control module are interconnected by signals. The data acquisition module includes an image recognition submodule and an analysis submodule. The image recognition submodule is electrically connected to the first camera 131, the second camera 141, and the third camera 151. The control module includes a conveying control submodule and a conveying spraying submodule. The conveying control submodule is electrically connected to the motor 213, the electric telescopic frame 221, the transport robot 15, the workshop pipeline connection box 16, the electric telescopic rod 322, and several sets of gripper assemblies 321. The conveying spraying submodule is electrically connected to the first spraying robot 13, the second spraying robot 14, and six sets of electric valves.

[0020] The transportation control system includes the following specific operating methods: Step 1: When the lampshade painting line needs to be processed, the staff first manually places the lampshade on the workshop conveyor line in the lampshade feeding room 17 and pushes it to one side of the transport robot 15.

[0021] Step 2: Start the spraying component 2 and the transport component 3 to grab and transport the lampshade; Specifically, the transport control system first controls the third camera 151 to detect the position of the lampshade through the image recognition submodule, and then controls the transport robot 15 to start through the transport control submodule to insert and place the lampshade on the fourth transport frame 35. Then, the transport control system controls several sets of gripper assemblies 321 to start through the transport control submodule, so that the electric telescopic rods 322 in the two sets of gripper assemblies 321 closest to the transport robot 15 are in the extended state, and the electric telescopic rods 322 in the other four sets of gripper assemblies 321 are retracted downwards. At this time, the transport control system detects whether the lampshade on the fourth transport frame 35 is in an inclined position through the third camera 151, so as to facilitate the subsequent spraying operation inside the lampshade. If the lampshade is in an inclined position, the transport control system controls the electric telescopic rods 322 in the four sets of gripper assemblies 321 to stop retracting and prepare for the next operation. If the lampshade is not in an inclined position, the transport control system does not operate.

[0022] Furthermore, after completing the above operations, the transport control system controls the motor 213 to start through the transport control submodule. The motor 213 drives the rotating conveyor 31 to rotate in the forward direction. At this time, the transport control system detects the position of the first conveyor 32 through the third camera 151. When the first conveyor 32 rotates to one side of the transport robot 15, the transport control system controls the motor 213 to stop and repeats the above placement operation. After the placement is completed, the transport control system controls the motor 213 to reset.

[0023] By taking the above steps, the position of the lampshade is adjusted before spraying, so that it is placed at an angle. The tilt of the lampshade is pre-adjusted to ensure that the workpiece posture is consistent during the subsequent spraying process inside the lampshade, avoiding uneven spraying or spraying dead corners, which helps to ensure the uniformity and consistency of the final coating quality.

[0024] Step 3: After the grabbing and conveying is completed, start the spraying component 2 to perform spraying processing on the inside and outside of the lamp cover; Specifically, during the above operations, the transport control system controls the first camera 131 to detect the position of the lampshade through the image recognition submodule. When the fourth conveyor 35 rotates the lampshade to the position of the first camera 131, the transport control system controls the motor 213 to stop, and the first spraying robot 13 starts. The first spraying robot 13 sprays liquid paint into the inside of the lampshade. After the spraying is completed, the transport control system controls the first camera 131 through the image recognition submodule to detect whether the inside of the lampshade is evenly sprayed. If the spraying is even, the transport control system controls the four sets of gripper assemblies 32. The electric telescopic rod 322 in section 1 extends upward, bringing the six sets of gripper assemblies 321 to the same height, facilitating subsequent spraying operations on the exterior of the lampshade. If the spraying is uneven or there are dead corners, the transport control system controls the retraction length of the electric telescopic rod 322 in the four sets of gripper assemblies 321 to decrease, reducing the tilt angle of the lampshade. This facilitates replenishing the flow of liquid paint during spraying and prevents the liquid paint from accumulating on the bottom edge inside the lampshade, resulting in uneven spraying thickness. Then, the transport control system controls the first spraying robot 13 to increase the spraying volume and replenish the spraying in uneven areas.

[0025] Furthermore, after completing the internal spraying operation of the lampshade, the transport control system starts the motor 213, which drives the rotating conveyor 31 to rotate forward. At this time, the transport control system detects the position of the lampshade through the second camera 141. When the fourth conveyor 35 drives the lampshade to rotate below the second spraying robot 14, the transport control system stops the motor 213 and starts the second spraying robot 14. The second spraying robot 14 sprays liquid paint onto the outer surface of the lampshade. After the spraying is completed, the transport control system controls the second camera 141 through the image recognition submodule to detect whether the outer surface of the lampshade is sprayed evenly. If the spraying is even, the transport control system starts the motor 213, which drives the rotating conveyor 31 to rotate forward, so that the fourth conveyor 35 drives the lampshade to rotate to the transport robot 15 for unloading. If the spraying is uneven or there are dead corners, the transport control system controls the second spraying robot 14 to increase the spraying volume and perform secondary spraying on the uneven areas.

[0026] Through the above steps, the inside and outside of the lampshade can be sprayed during transportation. After the inside of the lampshade is sprayed, a second inspection is carried out to ensure that there are no dead corners in the spraying. The tilt angle of the lampshade is adjusted so that the liquid paint sprayed inside the lampshade can flow and level by gravity. At the same time, it is convenient for the liquid paint to flow out during the second spraying. It prevents the liquid paint from accumulating on the bottom edge of the inside of the lampshade, which would cause uneven spraying thickness and affect subsequent production processing. After the outside of the lampshade is sprayed, a second inspection is carried out, and the spraying amount is increased to touch up the defective areas.

[0027] Step three also includes the following specific operational steps: Step 3-a: During the spraying operation of the first spraying robot 13, the transport control system controls the dust removal operation. Specifically, for example, when the fourth conveyor 35 rotates the lampshade to the first spraying robot 13 for internal spraying, the transport control system activates the electric telescopic frame 221 on the fourth flexible hose 25, causing the fourth flexible hose 25 to rise and engage with the corresponding pipe connection seat 326 on the fourth conveyor 35. At this time, the magnetic suction plate 223 on the fourth flexible hose 25 attracts the pipe connection seat 326, making the sealing cap 222 tightly fit with the pipe connection seat 326. Then, the transport control system controls the second electric valve 261, the fifth electric valve 264, and the sixth electric valve 265 to open through the conveying and spraying submodule, and the workshop dust collection device is activated. At this time, the gripper assembly 321 on the fourth conveyor 35 begins to perform paint mist removal. The cleaning holes 324 on the gripper assembly 321 remove the paint mist from the inside of the lampshade. The generated water mist is drawn into the third conveying pipe 325, then transported through the built-in pipes of the fourth conveying frame 35 to two sets of fourth conveying pipes 327, and then from the pipe connection seat 326 to the fourth flexible hose 25. Finally, it is transported through the second conveying pipe 212 to the workshop dust collection device for centralized collection. While the above operations are being performed, the transport control system controls the electric telescopic frame 221 on the second flexible hose 23 to start simultaneously. The second flexible hose 23 rises up and comes into contact with the pipe connection seat 326 corresponding to the second conveying frame 33. At this time, the gripper assembly 321 on the second conveying frame 33 begins to perform a pre-cleaning operation. The cleaning holes 324 on the gripper assembly 321 draw the floating dust and humid gas inside the lampshade into the third conveying pipe 325 to perform a pre-cleaning operation on the newly placed lampshade to avoid the floating dust affecting the coating effect of the liquid coating.

[0028] Furthermore, after completing the above steps, the transport control system controls the second hose 23 and the fourth hose 25 to descend and reset.

[0029] Through the above steps, while the inside of the lampshade is being sprayed, the generated paint mist is immediately sucked into the workshop dust collection device, achieving zero-time-difference synchronization between spraying and mist removal. This effectively avoids coating particle and sagging defects caused by secondary settling of paint mist, ensuring the smoothness and uniformity of the spraying. Secondly, while the spraying operation is underway, the second hose 23 is controlled to pre-clean the lampshade to be sprayed, which has been placed on another conveyor rack, removing floating dust and moisture in advance to prevent quality problems such as decreased adhesion of the coating film, thereby improving the product qualification rate.

[0030] Step 3-b: During the spraying operation of the second spraying robot 14, the transport control system controls the ventilation operation. Specifically, for example, when the fourth conveyor 35 rotates the lampshade to the second spraying robot 14 for external spraying of the lampshade, the transport control system controls the electric telescopic frame 221 on the third hose 24 to start, causing the third hose 24 to rise and fit together with the pipe connection seat 326 corresponding to the third conveyor 34. At this time, the magnetic suction plate 223 on the third hose 24 attracts each other with the pipe connection seat 326, making the sealing cap 222 fit tightly with the pipe connection seat 326. Then, the transport control system controls the first electric valve 26, the third electric valve 262, and the fourth electric valve 263 to open through the conveying spraying submodule, and the workshop ventilation device is activated. At this time, the gripper assembly 321 on the third conveyor 34 begins to perform ventilation and drying operations. The workshop ventilation device blows air into the first conveying pipe 211, then splits it into the third hose 24, and blows it into the two sets of the third hose after passing through the pipe connection seat 326. In the four delivery pipes 327, the liquid coating is finally blown into the third delivery pipe 325 through the built-in pipe of the third delivery frame 34 and then blown out through the cleaning hole 324 into the interior of the lampshade. This dries the liquid coating sprayed inside the lampshade and creates an air barrier around the inside of the lampshade, preventing the liquid coating sprayed outside the lampshade from drifting into the interior and causing changes in the uniformity of the coating. While the above operation is being performed, the transport control system controls the electric telescopic frame 221 on the first hose 22 to start simultaneously. The first hose 22 rises up and comes into contact with the pipe connection seat 326 corresponding to the first delivery frame 32. At this time, the gripper assembly 321 on the first delivery frame 32 begins to perform a pre-treatment operation. The cleaning hole 324 on the gripper assembly 321 performs a secondary drying operation on the humid gas inside the lampshade, and dries the lampshade that has just been placed, so as to prevent residual moisture inside the lampshade from affecting the coating effect of the liquid coating.

[0031] Furthermore, after completing the above steps, the transport control system controls the first hose 22 and the third hose 24 to descend and reset.

[0032] Through the above steps, while spraying the exterior of the lampshade, the liquid paint sprayed inside the lampshade is rapidly dried through the sealed connection between the third hose 24 and the third conveyor 34. This accelerates the curing process and prevents sagging or wrinkling caused by undried internal coatings. At the same time, the continuously blown airflow forms an outward air barrier around the inside of the lampshade, effectively preventing paint mist generated during external spraying from drifting into the lampshade. This avoids secondary contamination of the already sprayed surface or changes in coating uniformity, ensuring the independent quality of the inner and outer coatings. Simultaneously, it allows for secondary drying pretreatment of the lampshade on another conveyor, further removing residual moisture inside the lampshade and providing a drier and cleaner substrate surface for subsequent spraying. This effectively prevents defects such as coating bubbles and reduced adhesion caused by moisture.
