Description

Technical Field

[0001] This utility model relates to the field of tin bar surface treatment technology, and in particular to a tin bar surface treatment device with a dust removal device. Background Technology

[0002] Tin bars are a type of metal material with tin as the main component. They are usually made into bars through smelting, casting, or extrusion processes and are widely used in many fields such as electronics, electrical, hardware, chemicals, and food packaging. During the processing of tin bars, after the tin bars are taken out of the mold, their surfaces need to be polished to remove surface burrs and other defects, thereby improving the surface smoothness. In order to reduce the environmental impact of debris and dust generated during the polishing process, dust removal devices are usually used to treat debris and dust.

[0003] Currently, the most common technology is to use a vacuum cleaner to absorb the debris and dust generated during polishing. However, when vacuuming dust, the suction head is usually fixed, and the dust particles generated during polishing are easily suspended in the air. When using a fixed suction head, the suction path is singular, which can easily lead to some suspended dust not being fully absorbed, thus affecting the dust treatment effect. Utility Model Content

[0004] Therefore, it is necessary to provide a tin bar surface treatment device with a dust removal device to address the problem that using a fixed adsorption head to adsorb debris and dust generated during polishing has a single adsorption path, which easily leads to some suspended dust not being fully adsorbed, thus affecting the dust treatment effect.

[0005] Includes: a workbench, on the top of which is mounted an automatic polishing machine; The dust removal mechanism includes a protective cover fixedly connected to the top of the workbench. Two circular tubes are rotatably connected to the inner walls of the protective cover, and a dust collection frame is connected to the surface of each circular tube. A collection box is fixedly connected to the bottom of the workbench, and the collection box communicates with the opening at the top of the workbench. A fan is installed at the bottom of the collection box. Connecting pipes are connected to both sides of the collection box. One end of each of the two circular tubes passes through the protective cover and is rotatably connected to the corresponding connecting pipe. A filter plate is fixedly connected to the inner wall of the collection box, and a drive assembly is provided on one side of the protective cover.

[0006] In one embodiment, the drive assembly includes a motor fixedly connected to one side of the protective cover. A reciprocating lead screw is fixedly connected to the output shaft of the motor. A movable plate is provided on the surface of the reciprocating lead screw, and two racks are fixedly connected to the bottom end of the movable plate. Gears are fixedly connected to the surfaces of both cylindrical tubes, and the two racks mesh with the two gears respectively. This facilitates driving the two cylindrical tubes to rotate the two dust collection frames alternately to adsorb dust and debris inside the protective cover.

[0007] In one embodiment, a plurality of evenly distributed round rods are rotatably connected to the inner wall of the opening at the top of the workbench. The horizontal height of the upper surface of the round rods is flush with the horizontal height of the top of the workbench. When the solder bar is pushed to move and drive the round rods to rotate, it helps to make the debris on the round rods fall downwards more effectively.

[0008] In one embodiment, the opening of the dust collection frame is funnel-shaped, and a filter screen is embedded in the inner wall of the dust collection frame. This facilitates better adsorption of debris and dust, while separating larger debris to prevent it from entering the round tube and connecting tube and causing blockage.

[0009] In one embodiment, a plurality of evenly distributed scraper rods are fixedly connected to the inner wall of the opening at the top of the workbench. The number of scraper rods is the same as the number of round rods, and one side of each scraper rod is attached to the lower end of the surface of the corresponding round rod. This facilitates the scraping off of debris adhering to the round rods during their rotation.

[0010] In one embodiment, a sealed bearing is fixedly connected to the surface of one end of the circular tube, and the outer edge of the sealed bearing is fixedly connected to the inner wall of the connecting tube. This ensures the sealing of the connection between the circular tube and the connecting tube during rotation.

[0011] In one embodiment, a collection frame is slidably connected to the upper inner wall of the collection box, and the surface of the collection frame is in contact with the inner wall of the collection box. This facilitates the collection of larger impurities and prevents larger impurities from remaining on the filter plate and affecting the ventilation of the filter plate.

[0012] In one embodiment, the filter plate has an overall "V" shape and is inclined. This facilitates the movement and accumulation of debris and dust impurities that fall onto the filter plate towards the lower end of the plate.

[0013] Beneficial effects 1. The dust removal mechanism described above uses a protective cover to intercept and block the debris and dust generated during the polishing process. Starting the fan creates negative pressure inside the collection box, causing the two suction frames located on either side of the solder bar to adsorb the debris and dust generated during polishing. Under the action of the drive assembly, the two round tubes rotate synchronously, allowing the two suction frames to adsorb debris and dust while rotating alternately. This continuously changes the path of dust and debris adsorption, expanding the adsorption range and ensuring sufficient adsorption of smaller debris and dust within the protective cover, thus guaranteeing effective dust and debris handling during solder bar polishing. 2. The rotating rod in the above dust removal mechanism facilitates the synchronous rotation of the rod during the polishing process, allowing the debris on the rod to fall downwards more effectively. In conjunction with the scraper rod, the rod effectively scrapes off the debris adhering to it during rotation, thereby improving the debris collection efficiency. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-6 This invention describes a surface treatment device for tin bars with a dust removal unit.

[0019] In one embodiment, a tin bar surface treatment device with a dust removal device includes: a workbench 100, an automatic polishing machine 200 mounted on the top of the workbench 100; a dust removal mechanism 300, the dust removal mechanism 300 including a protective cover 310 fixedly connected to the top of the workbench 100, round tubes 340 rotatably connected to both sides of the inner wall of the protective cover 310, a dust collection frame 341 communicating with the surface of the round tubes 340, a collection box 320 fixedly connected to the bottom of the workbench 100, the collection box 320 communicating with the top opening of the workbench 100, a fan 330 mounted on the bottom of the collection box 320, connecting pipes 321 communicating with both sides of the collection box 320, one end of each of the two round tubes 340 passing through the protective cover 310 and rotatably connected to the corresponding connecting pipe 321, a filter plate 322 fixedly connected to the inner wall of the collection box 320, and a drive assembly 350 provided on one side of the protective cover 310.

[0020] In this embodiment, the front end of the protective cover 310 is set as a transparent plate to facilitate the worker to pass through during polishing. Both sides of the lower end of the protective cover 310 are provided with openings. When polishing the solder bar, the worker can pass the solder bar horizontally through the protective cover 310 along the openings.

[0021] The automatic polishing machine 200 includes an electric motor and a polishing roller. The output shaft of the electric motor is in contact with one end of the polishing roller. The electric motor is fixedly connected to the top of the worktable 100. The polishing roller is located inside the protective cover 310, and the rotating shaft of the polishing roller is rotatably connected to the inner wall of the protective cover 310. The center point of the polishing roller and the center point of the openings on both sides of the protective cover 310 are on the same vertical plane.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, the drive assembly 350 includes a motor 351 fixedly connected to one side of the protective cover 310. The output shaft of the motor 351 is fixedly connected to a reciprocating screw 352. A movable plate 353 is provided on the surface of the reciprocating screw 352. Two racks 354 are fixedly connected to the bottom end of the movable plate 353. Gears 355 are fixedly connected to the surfaces of the two round tubes 340. The two racks 354 are respectively meshed with the two gears 355.

[0023] In this embodiment, when the motor 351 is started by the controller, the output shaft of the motor 351 will drive the reciprocating screw 352 to rotate, and drive the moving plate 353 to drive the two racks 354 to move up and down reciprocally, thereby driving the two gears 355 to drive the corresponding round tube 340 to rotate reciprocally. The rotation direction is the same, and the round tube 340 rotates reciprocally between 60 degrees clockwise and 60 degrees counterclockwise. The reciprocating rotation effect is best within this set angle. The specific reciprocating rotation angle can be set according to the actual situation.

[0024] Since in the initial state, the opening of one vacuum frame 341 is tilted downwards and the opening of the other vacuum frame 341 is tilted upwards, when the two racks 354 move downwards and drive the two gears 355 to rotate counterclockwise, one of the round tubes 340 drives the vacuum frame 341 to gradually rotate until the opening is tilted upwards, and the other round tube 340 drives the vacuum frame 341 to gradually rotate until the opening is tilted downwards. When the two racks 354 move upwards, the two round tubes 340 drive the corresponding vacuum frames 341 to reset and rotate.

[0025] like Figure 6 As shown, multiple evenly distributed round rods 370 are rotatably connected to the inner wall of the top opening of the worktable 100, and the horizontal height of the upper surface of the round rods 370 is flush with the horizontal height of the top of the worktable 100.

[0026] In this embodiment, when the solder bar is placed on the workbench 100 and passes horizontally through the protective cover 310, the solder bar will come into contact with the round rod 370, and during the movement of the solder bar, it will drive the round rod 370 to rotate synchronously.

[0027] like Figure 4 As shown, the opening of the vacuum cleaner frame 341 is funnel-shaped, and a filter screen 342 is embedded in the inner wall of the vacuum cleaner frame 341.

[0028] In this embodiment, the mesh diameter of the filter screen 342 is larger than that of the filter plate 322. During the process of dust and debris adsorption by the dust collection frame 341, the filter screen 342 will intercept larger debris, and some debris will fall downwards under its own weight. When the dust collection frame 341 stops adsorption, the debris retained on the filter screen 342 loses adsorption and falls downwards under its own weight.

[0029] like Figure 6 As shown, a plurality of evenly distributed scraper rods 380 are fixedly connected to the inner wall of the top opening of the worktable 100. The number of scraper rods 380 is the same as the number of round rods 370. One side of each scraper rod 380 is attached to the lower end of the surface of the corresponding round rod 370.

[0030] In this embodiment, the scraper 380 is inclined. When the round rod 370 rotates, the scraper 380 scrapes the surface of the round rod 370 by adhering to the surface of the round rod 370.

[0031] like Figure 4 As shown, a sealed bearing 360 is fixedly connected to the surface of one end of the circular tube 340, and the outer edge of the sealed bearing 360 is fixedly connected to the inner wall of the connecting tube 321.

[0032] In this embodiment, the inner edge of the sealing bearing 360 is fixedly connected to the surface of the circular tube 340. Therefore, when the circular tube 340 rotates, the sealing bearing 360 ensures that the circular tube 340 and the connecting tube 321 are connected and sealed.

[0033] like Figure 5 As shown, a collection frame 323 is slidably connected to the upper end of the inner wall of the collection box 320, and the surface of the collection frame 323 is in contact with the inner wall of the collection box 320.

[0034] In this embodiment, the top opening of the collection box 320 is connected to the top opening of the workbench 100. Therefore, when larger debris falls down from the top opening of the workbench 100, it will enter the collection frame 323. Under the action of the collection frame 323, when the fan 330 is started, the two connecting pipes 321 will form a negative pressure adsorption.

[0035] like Figure 5 As shown, the overall shape of the filter plate 322 is "V" shaped, and the filter plate 322 is set at an angle.

[0036] In this embodiment, the connection between the two connecting pipes 321 and the collection box 320 is located above the higher end of the filter plate 322. When debris and dust impurities enter the collection box 320 and remain on the filter plate 322, some debris will move along the slope of the filter plate 322 to the lower part of the filter plate 322.

[0037] Working principle: When polishing the surface of the solder bar, the controller starts the fan 330 to expel the air from the collection box 320, creating a negative pressure adsorption between the two connecting pipes 321 and the two round pipes 340. This causes the dust collection frame 341 to adsorb the external air. Simultaneously, the controller starts the drive assembly 350, which drives the two round pipes 340 to rotate back and forth, thereby causing the two dust collection frames 341 to rotate alternately. The controller also starts the automatic polishing machine 200. At this time, the operator places the solder bar to be polished on the workbench 100 and passes it horizontally through the opening of the protective cover 310. The solder bar then passes horizontally through the polishing roller of the automatic polishing machine 200. The lower end of the surface contacts the surface of the solder bar, and the polishing operation is carried out during the horizontal penetration process. During this process, the two dust collection frames 341 rotate back and forth alternately to absorb the dust and debris generated during polishing. The absorbed debris and dust enter the collection box 320 and remain on the filter plate 322. The sucked-in air is discharged through the fan 330. During the adsorption process, some larger debris will fall into the collection frame 323 through the opening at the top of the workbench 100 under its own gravity. Some debris that falls on the round rod 370 will fall into the collection frame 323 for collection as the round rod 370 is driven to rotate horizontally by the solder bar. After polishing is completed, the drive assembly 350 and the fan 330 can be turned off.

[0038] Note: The reciprocating screw 352 is represented by two threaded grooves with the same pitch and opposite directions, connected at both ends by a transition curve. The rotation of the reciprocating screw 352 causes the side of the helical groove to push the slider placed in the helical groove to make axial reciprocating motion. Therefore, when the reciprocating screw 352 rotates, it will drive the moving plate 353 to move up and down reciprocally.

[0039] It should be noted that the motors, fans, and electric motors mentioned above are all devices with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the motors, fans, and electric motors can be powered by built-in power supplies or by mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
