Description

TECHNICAL FIELD

[0001] The application relates to the technical field of television production, in particular to a polishing and electric welding integrated device for television production. BACKGROUND

[0002] In the television production process, the processing of metal parts such as shells and frames needs to go through two key procedures of welding and polishing. The welding procedure is used for splicing and shaping scattered metal components, and the polishing procedure is used for removing the welding bumps, burrs and oxide layers remaining after welding, so as to ensure the surface flatness and assembly accuracy of the parts. The polishing and electric welding integrated device for television production is an automatic integrated device specially designed for television structure production, which can simultaneously or consecutively complete the welding shaping and post-welding polishing treatment. The device is usually equipped with an automatic control system, and can realize automatic switching of workstations and precise adjustment of welding parameters and polishing intensity.

[0003] Chinese patent document CN215967376U discloses a polishing and electric welding integrated device for television production, which comprises a base placed on the ground, and a first conveying belt and a second conveying belt are respectively installed on the inner side of the right rear end and the inner side of the left front end of the base. A belt shaft worm gear is arranged at equal intervals on the inner side of the left rear end of the base, and a sleeve rod is fixedly connected to the front end outer side of the belt shaft worm gear. A baffle is located above the front end of the belt shaft worm gear, and the baffle is fixedly connected with the base, and a rubber pad is attached to the left end of the base.

[0004] Although the production device can absorb dust during polishing, harmful smoke will be generated during welding, and a large amount of metal debris will be generated during polishing. Moreover, the device can only absorb the dust generated during polishing, and when the volume of the splashed debris is large, the suction force of the extracted air cannot absorb the debris, so that the splashed debris not only pollutes the workshop, but also may scratch the skin of the operator or enter the gap of the equipment to affect the service life of the equipment.

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, a grinding and welding integrated device for television production includes a base 1, a transport component 2 on one side of the upper end of the base 1, a welding robotic arm 3 on the other side of the upper end of the base 1, a grinding component 4 on the transport component 2, and a protective component 5 on the grinding component 4.

[0034] The transport component 2 includes a base plate 21 fixedly connected to the base 1. A chip removal housing 22 is fixedly connected to the upper end of the base plate 21. A support frame 23 is rotatably connected to the middle of the upper end of the base plate 21. Multiple fixed backing plates 24 are fixedly arranged in an array at the upper end of the support frame 23. Clamping plates 25 are rotatably connected to the support frame 23 on the side of the multiple fixed backing plates 24 that are far apart from each other. A slide rail frame 26 is fixedly connected to the base plate 21 below the support frame 23. A slide rail groove 27 is opened in the middle of the upper end of the slide rail frame 26. Two arc-shaped frames 28 are fixedly connected inside the slide rail frame 26. Multiple movable rollers 29 are rotatably connected to the lower end of the clamping plate 25 located on the same side inside the slide rail frame 26. The arc-shaped frames 28 are located on both sides away from the welding robot arm 3 and the grinding component 4.

[0035] In this embodiment, multiple fixed plates 24 fixed in an array at the upper end of the support frame 23 form reference guards from the front, back, left, and right sides of the workpiece, ensuring that the initial placement position of workpieces from different batches is uniform, avoiding misalignment in subsequent processing due to loading offset, and laying the foundation for the accuracy of grinding and welding. The slide rail frame 26 located below the support frame 23 and fixed on the base plate 21 starts to move. At this time, the support frame 23 will drive the movable roller 29 to move through the clamping plate 25. The movable roller 29 in the inner cavity of the slide rail frame 26 slides along the slide rail groove 27 opened at its upper end. Since the movable roller 29 and the lower end of the clamping plate 25 are rotatably connected through a rotating shaft, the sliding of the movable roller 29 will drive the clamping plate 25 to rotate synchronously around the side wall of the support frame 23, and finally achieve a ring-shaped clamping from both sides of the workpiece.

[0036] Example 2, based on Example 1, further enables the polishing of the welded outer shell. For further details, please refer to [link to example]. Figure 6 , Figure 7 , Figure 8 as well as Figure 9As shown, the grinding assembly 4 includes a support housing 41 fixed on the base plate 21. An electric cylinder is fixedly connected to the lower middle part of the support housing 41. A grinding housing 42 is fixedly connected to the telescopic end of the electric cylinder. A bidirectional motor 43 is fixedly connected to the middle of the top wall of the grinding housing 42. A reciprocating lead screw 44 is fixedly connected to the two telescopic ends of the bidirectional motor 43. Both reciprocating lead screws 44 are rotatably connected inside the grinding housing 42. Movable frames 45 are fitted on the outer surfaces of both reciprocating lead screws 44. A connecting block 46 is slidably connected to the inner cavity of the movable frame 45. An elastic element is fixedly connected between the connecting block 46 and the inner wall of the movable frame 45. The connecting block 46 penetrates the inner wall of the grinding housing 42. A grinding mechanism 47 is provided below both connecting blocks 46. The grinding mechanism 47 is located directly above one of the fixed backing plates 24.

[0037] The grinding mechanism 47 includes a U-shaped frame 471 fixed to the lower end of the connecting block 46. The inner wall of the U-shaped frame 471 is symmetrically provided with open slots 472. The bottom walls of the two open slots 472 are fixedly connected with buffer springs 473. The upper ends of the buffer springs 473 are fixedly connected with movable blocks 478. The ends of the two movable blocks 478 that are close to each other are provided with arc-shaped slots 474. The top walls of the two arc-shaped slots 474 are rotatably connected with elastic springs 475. Arc-shaped blocks 476 are slidably connected in the two arc-shaped slots 474. The elastic springs 475 are fixedly connected to the arc-shaped blocks 476. A grinding element 477 is fixedly connected between the two arc-shaped blocks 476. The movable blocks 478 are slidably connected to the inner wall of the open slots 472. The two grinding elements 477 are in opposite directions.

[0038] It should be further explained that the electric cylinder at the lower end of the supporting housing 41 drives the grinding housing 42 to move up and down. The height can be adjusted according to the thickness of different parts of the TV workpiece, such as the edge of the outer shell and the splicing seam, to ensure that the grinding mechanism 47 is precisely close to the surface to be ground. The bidirectional motor 43 on the top wall of the grinding housing 42 starts, driving the reciprocating screw 44 to rotate. Since the movable frame 45 is confined inside the grinding housing 42 and is threadedly engaged with the reciprocating screw 44, the rotation of the screw is converted into the linear reciprocating motion of the movable frame 45. The movable frame 45 drives the grinding mechanism 47 to move synchronously through the connecting block 46. The grinding mechanism 47 achieves uniform reciprocating grinding of the workpiece, avoiding the problems of local over-grinding and under-grinding that are prone to occur in manual grinding. Inside the grinding mechanism 47, the buffer spring 473 in the U-shaped frame 471 can absorb the impact force during grinding, preventing the thin-walled workpiece of the TV, such as the shell, from deforming due to excessive force. The elastic spring 475 in the arc groove 474 pushes the arc block 476, so that the grinding part 477 on the arc block 476 is always in close contact with the workpiece surface. Even if there is a slight curvature on the workpiece surface, such as the rounded corner of the TV frame, the grinding coverage can be guaranteed through elastic deformation, significantly improving the flatness of the workpiece surface.

[0039] Example 3 further elaborates on the purpose of preventing debris from flying during polishing, based on Examples 1 and 2. Please refer to the following for details.Figure 10 as well as Figure 11 As shown, the protective component 5 includes a small sealing housing 51 fixed to the top wall of the supporting housing 41. A large sealing housing 52 is fixedly connected to the outer surface of the small sealing housing 51. A trapezoidal groove is opened in the middle of the bottom wall of both the small sealing housing 51 and the large sealing housing 52. A sealing frame 53 is slidably connected inside both the small sealing housing 51 and the large sealing housing 52. The sealing frame 53 is adapted to the trapezoidal groove. A permanent magnet 54 is embedded at the upper end of both sealing frames 53. A driving mechanism 55 is provided at the connection between the small sealing housing 51 and the large sealing housing 52.

[0040] The drive mechanism 55 includes a U-shaped tube 551 fixed to the top wall of the support housing 41. An electric telescopic rod 552 is fixedly connected inside the U-shaped tube 551. A conical block 553 is fixedly connected to the telescopic end of the electric telescopic rod 552. An inner conical ring 554 is fixed inside the U-shaped tube 551 above the conical block 553. The outer surface of the conical block 553 is adapted to the inner cavity of the inner conical ring 554. A piston rod 555 is slidably connected inside the U-shaped tube 551. A top cover 556 is fixedly connected to the upper end of the piston rod 555. Multiple air outlet slots 557 are arrayed on the outer surface of the top cover 556. A connecting plate 558 is symmetrically fixedly connected to the lower end of the top cover 556. An electromagnetic block 559 is embedded in the lower end of both connecting plates 558. The electromagnetic block 559 has the opposite magnetic properties to the permanent magnet 54. A vacuum pump is fixedly connected to one of the ports of the U-shaped tube 551.

[0041] In this embodiment, during implementation, the electric telescopic rod 552 inside the U-shaped tube 551, which is fixed to the top wall of the supporting housing 41, extends when energized in the drive mechanism 55. Its telescopic end pushes the conical block 553 to slide upward along the inner conical ring 554 fixed inside the U-shaped tube 551. The increased air pressure pushes the piston rod 555, which is slidably connected at both ends of the U-shaped tube 551, to extend upward along the tube body. The upper end of the piston rod 555 is fixedly connected to the top cover 556, thereby driving the top cover 556 to rise synchronously. The connecting plates symmetrically fixed at the lower end of the top cover 556... As the top cover 556 rises, the distance between the electromagnetic block 559 embedded at the lower end of the connecting plate 558 and the permanent magnet 54 embedded at the upper end of the sealing frame 53 decreases. Because the two have opposite magnetic properties, they will generate a magnetic force that brings them closer together, opening the lower openings of the small sealing shell 51 and the large sealing shell 52, completely covering the workpiece and grinding area on the transport assembly 2 within the sealed space. At this time, the air pump connected to one end of the U-shaped tube 551 starts, and can spray air downwards through the trapezoidal groove, forming an air curtain around the grinding component by the rapidly moving air.

[0042] It should be further noted that the air pump mentioned above is a conventional technical means in the prior art. In this solution, its working principle is only used to extract air and will not be explained in detail.

[0043] Furthermore, the working principle of this solution is explained in conjunction with the above embodiments: First, the TV workpiece to be processed is placed on the upper end of the support frame 23 of the transport component 2. Multiple fixed plates 24 fixed in an array on the upper end of the support frame 23 will form reference guards from the front, back or left and right sides of the workpiece to ensure that the initial placement position of different batches of workpieces is uniform, avoiding subsequent processing misalignment due to loading offset, laying the foundation for the accuracy of grinding and welding. The slide rail frame 26 located below the support frame 23 and fixed on the base plate 21 starts to move. At this time, the support frame 23 will drive the movable roller 29 to move through the clamping plate 25. The movable roller 29 in the inner cavity of the slide rail frame 26 slides along the slide rail groove 27 opened at its upper end. Since the movable roller 29 and the lower end of the clamping plate 25 are rotatably connected through a rotating shaft, the sliding of the movable roller 29 will drive the clamping plate 25 to rotate synchronously around the side wall of the support frame 23, and finally achieve a ring-shaped clamping from both sides of the workpiece. When the support frame 23 drives the workpiece to rotate to the lower end of the welding robot arm 3, the welding robot arm 3 will perform welding operations on the fixed workpiece.

[0044] The electric cylinder fixed at the lower middle of the support housing 41, which is fixed on the base plate 21, is energized and started. The telescopic end of the electric cylinder extends downward or retracts upward, driving the grinding housing 42, which is fixed to the telescopic end, to move up and down synchronously. During the adjustment process, the distance between the lower end face of the grinding mechanism 47 in the inner cavity of the grinding housing 42 and the workpiece surface to be ground is controlled by the stroke control of the electric cylinder. This avoids the grinding being incomplete due to excessive distance or the workpiece being damaged due to insufficient distance. The bidirectional motor 43 fixed at the middle of the top wall of the grinding housing 42 is energized and started. Its two output ends drive a reciprocating screw 44 to rotate synchronously. The two reciprocating screws 44 have opposite screw directions, but due to the limitation of the movable frame 45, only linear reciprocation is achieved. Since the movable frame 45 is sleeved outside the reciprocating screw 44 and is slidably connected to the inner wall of the grinding housing 42 to restrict rotation, the rotation of the reciprocating screw 44 is converted into linear reciprocating motion of the movable frame 45 along the length of the grinding housing 42. The reciprocating stroke can be controlled by the forward and reverse rotation time of the bidirectional motor 43.

[0045] The grinding mechanism 47 has symmetrically arranged open slots 472 on the inner wall of the U-shaped frame 471. Movable blocks 478 are slidably connected within the open slots 472, and a buffer spring 473 is fixed between the lower end of the movable block 478 and the bottom wall of the open slot 472. When encountering protrusions such as burrs on the workpiece surface during grinding, the movable block 478 compresses the buffer spring 473 and slides upward along the open slot 472 to absorb the grinding impact, preventing deformation of thin-walled workpieces such as the outer shell due to excessive force. An arc-shaped groove 474 is formed at one end of the movable blocks 478 that is close to each other, and a sliding connection is formed within the arc-shaped groove 474. An elastic spring 475 is fixed between the arc-shaped block 476 and the bottom wall of the arc-shaped groove 474, and a grinding component 477, such as sandpaper or a grinding wheel, is fixed between the arc-shaped blocks 476. The elastic force of the elastic spring 475 always pushes the arc-shaped block 476 outward, so that the grinding component 477 always adheres tightly to the surface of the workpiece. Even if there is a slight curvature on the surface of the workpiece, the grinding component 477 can achieve conformal grinding through the sliding of the arc-shaped block 476. The metal chips generated by grinding, such as iron chips and aluminum chips, fall naturally from the grinding part under the action of gravity, pass through the gap of the sealed space and fall into the chip removal housing 22 of the transport component 2.

[0046] The protective component 5 starts operating synchronously with the grinding process. It is fixed in the drive mechanism 55 on the top wall of the support housing 41. The electric telescopic rod 552 inside the U-shaped tube 551 extends when energized, and its telescopic end pushes the conical block 553 upwards along the inner cavity of the inner conical ring 554 fixed inside the U-shaped tube 551. Because the outer wall of the conical block 553 is tightly fitted to the inner wall of the inner conical ring 554, the upward movement of the conical block 553 compresses the gas inside the U-shaped tube 551, causing the gas pressure inside the tube to increase. The increased air pressure pushes the piston rod 555, which is slidably connected at both ends of the U-shaped tube 551, to extend upward along the tube body. The upper end of the piston rod 555 is fixedly connected to the top cover 556, thereby driving the top cover 556 to rise synchronously. The connecting plate 558, which is symmetrically fixed at the lower end of the top cover 556, rises with the top cover 556. The distance between the electromagnetic block 559 embedded at the lower end of the connecting plate 558 and the permanent magnet 54 embedded at the upper end of the sealing frame 53 decreases. Because the two have opposite magnetic properties, they will generate a magnetic force that brings them closer together.

[0047] The repulsive force pushes the sealing frame 53 to slide upward along the trapezoidal grooves opened on the inner walls of the small sealing shell 51 and the large sealing shell 52, and finally opens the lower openings of the small sealing shell 51 and the large sealing shell 52, completely covering the workpiece and grinding area on the transport component 2 within the sealed space. At this time, the air pump connected to one end of the U-shaped tube 551 starts and can spray air downward through the trapezoidal groove. The rapidly moving air forms an air curtain around the grinding component, preventing grinding debris from splashing and welding fumes from spreading and polluting the workshop environment. This protects the health of the operators and reduces the workload of subsequent cleaning processes. The grinding debris naturally falls into the chip removal shell 22, which is convenient for centralized cleaning and recycling, reducing material waste.

[0048] After the work stops, the air pump is turned off first, then the bidirectional motor 43 stops, the grinding housing 42 is reset to the initial height by the electric cylinder, then the electric telescopic rod 552 is energized and shortened, driving the conical block 553 to reset downward along the inner conical ring 554, the air pressure in the U-shaped tube 551 is restored to atmospheric pressure, the piston rod 555 slides downward along the U-shaped tube 551 under the action of gravity, driving the top cover 556 to descend synchronously. After the top cover 556 descends, the distance between the electromagnetic block 559 and the permanent magnet 54 increases, the repulsive force disappears, and the sealing frame 53 slides towards the middle along the trapezoidal groove under the action of gravity, resealing the openings of the small sealing housing 51 and the large sealing housing 52, completing the reset of the protective component 5. This reset structure is simple and reliable, reducing the probability of mechanical failure. Then the clamping plate 25 slides in the opposite direction with the movable roller 29 to release the workpiece, and the support frame 23 transports the processed workpiece to the unloading station, thus completing a single processing flow.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
