A plasma welding device for garbage bins

Abstract

This invention provides a plasma welding device for garbage bins, including a frame, a processing mechanism, a docking mechanism, and a welding mechanism on the frame. The processing mechanism includes a processing rack on one side of the frame, a conveyor belt on top of the rack, and bin side panels placed on the conveyor belt. The processing mechanism also includes a rotating component, a stamping component, a bending component, and an adhesive application component on the processing rack. This invention uses the processing mechanism to bend the two sides of the bin side panels to 45 degrees and pre-applies halogen-modified adhesive at the bend. The docking mechanism then assembles four sets of bin side panels vertically to form the outer perimeter of the garbage bin. The bends formed by the bending of adjacent bin side panels create a V-shaped groove upon contact. This V-shaped groove optimizes the stress distribution of the weld, improving welding strength. The halogen-modified adhesive ensures the stability of the side panels during welding, and the decomposition of the flux components in the adhesive during welding enhances the welding effect.

Description

Technical Field

[0001] This invention relates to the field of garbage bin manufacturing technology, and in particular to a plasma welding device for garbage bins. Background Technology

[0002] Trash cans are containers used to store garbage and are commonly used in public places such as communities and parks. Their core function is to serve as the final facility for garbage collection, providing a physical barrier to temporarily store garbage and laying the foundation for subsequent collection and processing.

[0003] Plasma arc welding is a welding process that uses the thermal energy of a plasma arc to weld metals or non-metals. It features a stable arc, concentrated heat, a small heat-affected zone, minimal deformation, and high productivity. It can be used to weld refractory, easily oxidized, and heat-sensitive materials, such as molybdenum, tungsten, beryllium, chromium, tantalum, nickel, titanium and their alloys, and stainless steel.

[0004] Chinese patent CN202410377538.8 discloses a plasma arc welding device. A drive mechanism and a clamping mechanism are provided in a groove at the upper end of the worktable. The clamping mechanism includes a slide rail mechanism centrally located within the groove and clamping frames slidably connected to the slide rail mechanism on both sides. An isolation mechanism is movably connected between the two clamping frames. The arc welding mechanism includes two sets of connecting plates fixed at the lower center of the support base, a rotating frame movably connected between the front and rear parts of the two sets of connecting plates, and a mounting frame at the end of the rotating frame. The mounting frame contains a rotating shaft driven by a first motor, with pressure rollers fixed at both ends of the rotating shaft. Driven by the drive mechanism, this invention can clamp and fix two workpieces to be welded. While continuously welding the two sets of workpieces, it removes dust and debris from the gap between the rear parts of the two sets of workpieces, thus improving welding quality.

[0005] However, this technical solution has certain shortcomings in its use. When welding garbage bins, due to the thinness of the outer side plates, a significant temperature gradient is formed between the local high-temperature area and the surrounding cold area during welding, resulting in concentrated thermal stress. After cooling, the shrinkage is uneven, which easily produces wavy or bending deformation. As a result, the weld seam of the traditional welding method cannot guarantee the stress-bearing effect. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a plasma welding device for garbage bins. This device achieves welding functionality through a processing mechanism in conjunction with a docking mechanism, thus solving the problem of difficulty in ensuring the stress resistance of the weld.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0013] The adhesive application assembly further includes: an extrusion base, two sets of which are fitted into two sets of fitting grooves, the extrusion base storing halogen-containing flux-modified adhesive, the halogen-containing flux-modified adhesive being made with epoxy resin as the matrix and incorporating halogen-containing active flux; a dispensing nozzle, the dispensing nozzle being connected through the two sets of extrusion bases; a dispensing groove, the dispensing groove being opened on one side of the extrusion base; an extrusion plate, the extrusion plate being movably connected within the extrusion base; and telescopic columns, two sets of which are disposed on the extrusion plate.

[0014] The docking mechanism includes a rotating frame b mounted on the device frame, a turntable b movably connected to the rotating frame b, a connecting top plate fixedly connected to the top of the turntable b, a motor d mounted on one side of the rotating frame b, and multiple sets of connecting parts fixedly connected to the outer side of the connecting top plate. The docking mechanism includes four sets of splicing components located on the outer side of the connecting top plate.

[0015] Each of the four splicing components includes: a splicing frame, which is fixedly connected to the outside of the connecting top plate; a flipping end, which is located inside the splicing frame; two sets of casters, which are installed at the bottom of two sets of support legs on the outside of the splicing frame; a guide plate, which is located outside the splicing frame; a flipping frame, which is movably connected inside the splicing frame; a flipping rod, which is fixedly connected to the inside of the flipping frame; an input rod, which is located below the flipping rod; a connecting rod, which is movably connected to both sides of the flipping frame; a cylinder, which is installed on the splicing frame, and the cylinder output rod is movably connected to the bottom end of the input rod; an assembly plate, which is installed on the flipping frame; guide rollers, which are movably connected to the four sets of assembly plates; and suction cups, which are installed on the four sets of assembly plates.

[0016] The welding mechanism includes a welding frame located on the top of the device frame, an X-axis displacement module on the welding frame, a Y-axis displacement module on the X-axis displacement module, a Z-axis displacement module inside the welding frame, and a plasma welding device on the X-axis displacement module.

[0017] The side panels of the box are bent at both sides with angles, and one side of each angle is bent into an arc. After the four sets of side panels of the box are vertically spliced ​​together, the adjacent angles fit together.

[0018] The beneficial effects of this invention are as follows:

[0019] (1) In this invention, the pressure strip on the power plate is pressed down by two sets of hydraulic cylinders. Supported and restricted by the bottom strip, the side of the box panel is slightly pressed up. After the pressure strip is retracted, the bottom strip is pushed to move towards the center of the box panel by the drive rod on the bottom strip until the right side of the bottom strip is aligned with the bottom end of the guide slope of the pressure strip. During the movement, the side of the box panel that is raised is slightly lifted to ensure that it is subjected to force later. The pressure strip is driven by two sets of hydraulic cylinders to squeeze the side of the box panel to ensure its stability. The two sets of motors b drive and the belt on the guide wheel a and guide wheel b drive the two sets of gear shafts to rotate. The meshing of the gears on the two sets of gear shafts and the gear b drives the pressure plate on the bottom shaft of the plate to deflect. The pressure of the pressure plate further bends the already raised side of the box panel along the guide slope of the pressure strip to complete the processing of one side.

[0020] (2) The present invention uses two sets of telescopic columns to apply pressure and drive the extrusion plate to move, so that the halogenated flux-modified glue stored in the extrusion seat is squeezed out from the glue outlet groove, so that the glue is soaked in the sponge sleeve, and the glue roller is rotated by two sets of motors c. The bottom gear c meshes with the rack, so that it can roll back and forth along the slide and guide rail. The glue is further applied by the contact between the sponge sleeve and the corner of the box side plate. The halogenated flux-modified glue is used to bond the box side plate during subsequent assembly to ensure the stability of subsequent welding.

[0021] (3) The present invention drives the bottom input rod of the flipping rod on the flipping frame by the cylinder, thereby pulling the flipping frame to flip along the flipping rod. The connecting rod at the other end of the flipping frame is stretched out by force, thereby realizing the vertical assembly of the four sets of bent box side panels and forming the outer perimeter of the garbage bin. At the same time, the corners of the two adjacent box side panels come into contact and are bonded by the pre-coated halogen-containing flux modified glue. The two adjacent box side panels form a V-shaped groove after contact through the folding arc formed by bending, as shown in the figure. The V-shaped groove increases the depth of the weld, optimizes the stress distribution of the weld, and improves the welding strength. The corner contact generated by bending increases the contact area of ​​the two sets of box side panels, thereby improving the heat conduction effect between the two sets of box side panels and reducing the deformation caused by different stress after welding cooling.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] Example 1: As Figures 1-16 As shown, this embodiment provides a plasma welding device for a trash can, including a device frame 1, and further including a processing mechanism 2, a docking mechanism 3 and a welding mechanism 4 on the device frame 1; the processing mechanism 2 includes a processing frame 201 disposed on one side of the device frame 1, a conveyor belt 202 disposed on the top of the processing frame 201, and a side plate 203 of the can being placed on the conveyor belt 202; the processing mechanism 2 includes a rotating component 21, a stamping component 22, a bending component 23 and an adhesive application component 24 disposed on the processing frame 201.

[0044] The rotating assembly 21 includes: a rotating frame a211, which is mounted on the processing frame 201; a traction motor 2111, which is mounted on one side of the processing frame 201; a traction wheel 2112, which is mounted on the output of the traction motor 2111; a turntable a212, which is movably connected to the rotating frame a211; a deflection frame 213, which is mounted on the turntable a212; a cover plate 214, which is fixedly connected to the deflection frame 213; a negative pressure device 215, which is mounted on the cover plate 214; a gear ring 216, which is fixedly connected to the outside of the turntable a212; a motor a217, which is mounted on the rotating frame a211; a gear a218; and a chain 219, which is connected between the gear ring 216 and the gear a218.

[0045] In this embodiment, the gear a218 is driven to rotate by the motor a217. The rotation of the gear a218 drives the turntable a212 to rotate through the connection and meshing of the chain 219. This causes the box side plate 203, which is adsorbed by the negative pressure device 215, to rotate. Furthermore, the side of the box side plate 203 that is connected to the stamping assembly 22 can be adjusted, thereby further realizing the processing of both sides of the box side plate 203.

[0046] The stamping assembly 22 includes: a stamping frame 221, which is mounted on the processing frame 201; a stamping seat 222, which is fixedly connected to the stamping frame 221; a power plate 223, which is movably connected to the stamping seat 222; two hydraulic cylinders 224, which are mounted on the stamping seat 222; a pressure strip 225, which is fixedly connected to the underside of the power plate 223, and a guide inclined end 2251 is provided on one side of the pressure strip 225, the inclined angle of the guide inclined end (2251) being forty-five degrees; and a bottom strip 226, which is fixedly connected to the stamping seat 222.

[0047] In this embodiment, two sets of hydraulic cylinders 224 drive the upper pressure bar 225 of the power plate 223 to press down, thereby raising the side of the box side plate 203, which facilitates subsequent pressure bending and presses the box side plate 203 tightly during bending, so that it bends at a 45-degree angle.

[0048] The bending assembly 23 includes: a support base rod 231, which is fixedly connected to the stamping seat 222; a pressure plate 232, which is movably connected to the support base rod 231; a plate bottom shaft 233, which is located at the bottom end of the pressure plate 232; gears b234, with two sets of gears b234 located at both ends of the plate bottom shaft 233; motors b235, with two sets of motors b235 mounted on both sides of the stamping seat 222; guide wheels a236, which are located at one end of the output shaft of the motors b235; gear shafts 237, with two sets of gear shafts 237 movably connected to both sides of the stamping seat 222, and the gears on the two sets of gear shafts 237 meshing with the two sets of gears b234; guide wheels b238, which are located at one end of the two sets of gear shafts 237; and a belt 239, which is connected between guide wheels a236 and guide wheels b238.

[0049] In this embodiment, two sets of motors b235 drive and belts 239 on guide wheels a236 and b238 to rotate two sets of gear shafts 237. The meshing of gears on the two sets of gear shafts 237 and gear b234 causes the pressure plate 232 on the bottom shaft 233 to deflect. The pressure of the pressure plate 232 further bends the already warped box side plate 203 along the guide inclined end 2251 of the pressure strip 225 to complete the processing.

[0050] The adhesive application assembly 24 includes: an adhesive application plate 241, which is fixedly connected to one side of the pressure plate 232; a cavity 2411, which is formed on the adhesive application plate 241; a receiving cavity 2412, which is formed on the inner walls of both sides of the cavity 2411; a sliding groove 2413, which is formed on the adhesive application plate 241; a rack 2414, which is fixedly connected to the adhesive application plate 241; a guide rail 2415, which is disposed on the adhesive application plate 241; and a fitting groove 241. 6. Two sets of fitting grooves 2416 are provided on both sides of the coating plate 241; two sets of coating rollers 242 are movably connected in the receiving cavity 2412, and the two sets of coating rollers 242 are movably connected to the sliding groove 2413; a sponge sleeve 2421 is provided on the outside of the coating roller 242; a motor c2422 is installed on the top of the coating roller 242; a gear c2423 is provided at the bottom of the coating roller 242, and the gear c2423 meshes with the rack 2414.

[0051] The adhesive application assembly 24 further includes: an extrusion seat 243, two sets of extrusion seats 243 being fitted into two sets of fitting grooves 2416, the extrusion seat 243 storing halogen-containing flux-modified adhesive, the halogen-containing flux-modified adhesive being made of epoxy resin as a matrix and incorporating halogen-containing active flux; a dispensing nozzle 2431, the dispensing nozzle 2431 being connected through the two sets of extrusion seats 243; a dispensing groove 2432, the dispensing groove 2432 being opened on one side of the extrusion seat 243; an extrusion plate 2433, the extrusion plate 2433 being movably connected within the extrusion seat 243; and telescopic columns 2434, two sets of telescopic columns 2434 being disposed on the extrusion plate 2433.

[0052] In this embodiment, under normal conditions, the coating roller 242 is housed in the storage cavity 2412. The elastic material of the sponge sleeve 2421 presses and seals the glue outlet groove 2432 of the extrusion seat 243. After the side panel 203 of the box is bent, the two sets of telescopic columns 2434 apply pressure to drive the extrusion plate 2433 to move, squeezing out the halogen-containing flux-modified glue stored in the extrusion seat 243 from the glue outlet groove 2432, so that the glue soaks the sponge. The sleeve 2421 is used to rotate the glue-applying roller 242 via two sets of motors c2422. The bottom gear c2423 meshes with the rack 2414, allowing it to roll back and forth along the slide groove 2413 and guide rail 2415. The glue is applied by contact between the sponge sleeve 2421 and the bend 2031 on the side panel 203 of the box. The side panel 203 of the box is then bonded with halogen flux-modified glue during subsequent assembly to ensure the stability of subsequent welding.

[0053] The docking mechanism 3 includes a rotating frame b301 mounted on the device frame 1, a turntable b302 movably connected to the rotating frame b301, a connecting top plate 303 fixedly connected to the top of the turntable b302, a motor d304 mounted on one side of the rotating frame b301, and multiple sets of connecting parts 305 fixedly connected to the outer side of the connecting top plate 303. The docking mechanism 3 includes four sets of splicing components 31 located on the outer side of the connecting top plate 303.

[0054] In this embodiment, the turntable b302 is rotated by the motor d304. The turntable b302 drives the splicing frame 311 to move as a whole by connecting multiple sets of connectors 305 on the top plate 303 to the splicing assembly 31, thereby further realizing the loading of the four sets of box side panels 203 before splicing.

[0055] Each of the four splicing components 31 includes: a splicing frame 311, which is fixedly connected to the outside of the connecting top plate 303; a flip end 312, which is located inside the splicing frame 311; two sets of casters 313, which are installed at the bottom of two sets of support legs on the outside of the splicing frame 311; a guide plate 314, which is located outside the splicing frame 311; a flip frame 315, which is movably connected inside the splicing frame 311; and a flip rod 3151, which is fixedly connected to the inside of the flip frame 315; and a conveyor belt. Input rod 3152 is located below flipping rod 3151; connecting rod 3153, two sets of connecting rods 3153 are movably connected to both sides of flipping frame 315; cylinder 316, cylinder 316 is mounted on splicing frame 311, and the output rod of cylinder 316 is movably connected to the bottom end of input rod 3152; assembly plate 317, four sets of assembly plates 317 are mounted on flipping frame 315; guide roller 318, four sets of guide roller 318 are movably connected to four sets of assembly plates 317; suction cup 319, four sets of suction cup 319 are mounted on four sets of assembly plates 317.

[0056] In this embodiment, the traction motor 2111 drives the traction wheel 2112 to rotate. Through the contact friction resistance between the traction wheel 2112 and the bent box side plate 203 on the rotating frame a211, the bent box side plate 203 is guided from the guide plate 314 to the flipping frame 315. Four sets of guide rollers 318 on the flipping frame 315 guide the plate and the plate is fixed by four sets of suction cups 319.

[0057] The cylinder 316 drives the bottom input rod 3152 of the flipping rod 3151 on the flipping frame 315, thereby pulling the flipping frame 315 to flip along the flipping rod 3151. The connecting rod 3153 at the other end of the flipping frame 315 is stretched out under force, thereby realizing the vertical assembly of the four sets of bent box side panels 203.

[0058] The side panels 203 of the box body are bent at both sides with angles 2031, and one side of the angles 2031 is bent with an arc 2032. After the four sets of side panels 203 are erected and spliced ​​together, the adjacent angles 2031 fit together.

[0059] In this embodiment, the V-shaped groove formed between the folded arcs 2032 at the contact point of two adjacent sets of box side plates 203 increases the depth of the weld, optimizes the stress distribution of the weld, and improves the welding strength. Furthermore, the fold angle 2031 generated by the bending increases the contact area between the two sets of box side plates 203, thereby improving the heat conduction effect between the two sets of box side plates 203 and reducing the deformation caused by different stresses after welding and cooling.

[0060] Example 2: Figure 17 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0061] The welding mechanism 4 includes a welding frame 401 located on the top of the device frame 1. An X-axis displacement module 402 is provided on the welding frame 401. A Y-axis displacement module 403 is provided on the X-axis displacement module 402. A Z-axis displacement module 404 is provided inside the welding frame 401. A plasma welding device 405 is provided on the X-axis displacement module 402.

[0062] In this embodiment, the position of the plasma welding equipment 405 is adjusted by the X-axis displacement module 402, the Y-axis displacement module 403 and the Z-axis displacement module 404, and the welding position is further finely adjusted by the lifting module and the rotary table of the plasma welding equipment 405 to carry out the welding operation.

[0063] Work steps

[0064] Step 1, Processing and feeding process: The side panel 203 of the box is transported to the cover plate 214 by the conveyor belt 202, and the side panel 203 of the box is positioned by the negative pressure device 215.

[0065] The motor a217 drives the gear a218 to rotate. The rotation of the gear a218 drives the turntable a212 to rotate through the connection and meshing of the chain 219. This causes the side plate 203 of the box to rotate, so that a set of sides of the side plate 203 of the box enters the stamping seat 222 and remains horizontal with the pressure strip 225.

[0066] Step 2, Bending Process: The pressure strip 225 on the power plate 223 is pressed down by two sets of hydraulic cylinders 224. Supported and restricted by the bottom strip 226, the side of the box side plate 203 is slightly pressed up. After the pressure strip 225 is retracted, the bottom strip 226 is pushed towards the center of the box side plate 203 by the drive rod on the bottom strip 226 until the right side of the bottom strip 226 is aligned with the bottom end of the guide inclined end 2251 of the pressure strip 225. During the movement, the side of the box side plate 203 that is raised is slightly lifted to ensure that it can withstand subsequent force.

[0067] Two sets of hydraulic cylinders 224 drive the pressure bar 225 to press the side plate 203 of the box body to ensure its stability;

[0068] Two sets of motors b235 drive the rotation of two sets of gear shafts 237 through the transmission of belts 239 on guide wheels a236 and b238. The meshing of gears on the two sets of gear shafts 237 and gear b234 causes the pressure plate 232 on the bottom shaft 233 to deflect. The pressure of the pressure plate 232 further bends the already warped side plate 203 along the guide inclined end 2251 of the pressure strip 225 to complete the 45-degree angle processing of a set of sides.

[0069] Step 3, Glue Application Process: Two sets of telescopic columns 2434 apply pressure to drive the extrusion plate 2433 to move, extruding the halogenated flux-modified glue stored in the extrusion seat 243 from the glue outlet 2432, so that the glue soaks the sponge sleeve 2421. Two sets of motors c2422 drive the glue application roller 242 to rotate, and the bottom gear c2423 meshes with the rack 2414, so that it can roll back and forth along the slide 2413 and the guide rail 2415. The glue is further applied by the contact between the sponge sleeve 2421 and the bend 2031 on the side plate 203 of the box. The halogenated flux-modified glue will bond the side plate 203 of the box during subsequent assembly, ensuring the stability of subsequent welding.

[0070] The other side of the box side plate 203 is rotated again by motor a217 and enters the stamping seat 222 for bending. Then, glue is applied to the other side of the box side plate 203.

[0071] Step 4, splicing and feeding process: The traction motor 2111 drives the traction wheel 2112 to rotate. Through the contact friction resistance between the traction wheel 2112 and the bent box side plate 203 on the rotating frame a211, the bent box side plate 203 is guided from the guide plate 314 to the flipping frame 315. Four sets of guide rollers 318 on the flipping frame 315 guide the plate and it is fixed by four sets of suction cups 319.

[0072] After the material is loaded, repeat steps one, two and three to process another set of side panels 203 of the container. During the processing of the other set, the turntable b302 is rotated by the motor d304. The turntable b302 drives the splicing frame 311 to move as a whole by connecting multiple sets of connectors 305 on the top plate 303 to the splicing assembly 31, so that the other set of splicing frame 311 docks with the rotating frame a211. When the processing of the other set is completed, the material can be loaded again by the traction wheel 2112 until all four sets of side panels that make up the outer perimeter of the garbage container are loaded.

[0073] Step 5, Assembly process: The cylinder 316 drives the bottom input rod 3152 of the flipping rod 3151 on the flipping frame 315, thereby pulling the flipping frame 315 to flip along the flipping rod 3151. The connecting rod 3153 at the other end of the flipping frame 315 is stretched out under force, thereby realizing the vertical assembly of the four sets of bent side panels 203 of the bin and forming the outer perimeter of the garbage bin.

[0074] Simultaneously, the 45-degree bends 2031 of adjacent side panels 203 come into contact, forming a 90-degree right angle, thus allowing for complete contact. This is achieved through bonding with pre-applied halogen-containing flux-modified adhesive. Furthermore, the bends 2032 formed by the bending of adjacent side panels 203 create a V-shaped groove upon contact. Figure 16 As shown, the depth of the weld is increased by the V-shaped groove, the stress distribution of the weld is optimized, and the welding strength is improved. The contact area between the two sets of box side plates 203 is increased by the bend 2031, so as to improve the heat conduction effect between the two sets of box side plates 203 and reduce the deformation caused by different stress after welding cooling.

[0075] Step 6, Welding process: The position of the plasma welding equipment 405 is adjusted by the X-axis displacement module 402, Y-axis displacement module 403 and Z-axis displacement module 404, and the welding position is further finely adjusted by the lifting module and the rotary table of the plasma welding equipment 405 to carry out the welding operation.

[0076] During welding, the welding head of the plasma welding equipment 405 is aligned with the V-shaped grooves of the two adjacent side plates 203 of the box for welding. During the welding process, the halogen-containing flux-modified adhesive on the corner 2031 will undergo local decomposition when heated, releasing Cl⁻ and Br⁻ halogen ions, effectively removing metal surface oxides such as Fe2O3, improving solder wettability, and effectively reducing solder surface tension and porosity defects.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
