Description

Technical Field

[0001] The present invention belongs to the technical field of welding, and particularly relates to a multi-angle welding device and method for processing outdoor sports equipment. Background Art

[0002] Soldering wire welding is a welding technology widely used in the connection and repair of electronic components, mainly using tin-based alloys as solder. It realizes electrical connection and mechanical fixation by heating the soldering wire to its melting point, making it melt and flow onto the surface of the metal to be welded.

[0003] In the welding of multi-layer circuit boards or complex components, it is necessary to preheat the preheated soldering wire during the transportation process before welding to reduce the temperature gradient and ensure that the entire welding area is welded at an appropriate temperature. Preheating will exacerbate the oxidation of the tin surface, damage the antioxidant coating and form a tin oxide film, reducing the wetting performance of the tin and causing a decrease in the adhesion of the welding interface. If a mechanism for isolating oxygen is added during the preheating process, the equipment cost will be too high, and the oxides in the welding fumes cannot be treated, resulting in poor practicability. This phenomenon has become an urgent problem for those in this field to solve. Summary of the Invention

[0009] The present invention is further described as follows. Mounting frames are correspondingly installed on the inner wall of the reduction reaction chamber. An electric heater is slidably installed on the outer wall of the mounting frame. An electric push rod is installed on the top of the mounting frame, and the output end of the electric push rod is connected to the electric heater.

[0010] The present invention is further described as follows. A tin liquid flow pipe is connected to the bottom of the reduction reaction chamber in a penetrating manner. One end of the tin liquid flow pipe is connected to a tin liquid outflow housing in a penetrating manner. The tin liquid outflow housing is fixed to a fixed seat. A wrapping pipe is arranged vertically through the tin liquid outflow housing. Electric heating wires are embedded in the inner walls of the tin liquid outflow housing and the tin liquid flow pipe. Discharge holes are evenly formed in the side wall of the wrapping pipe.

[0011] The present invention is further described as follows. A receiving groove is formed by inward extension of the wall where the discharge holes are located. A blocking block is slidably installed inside the receiving groove. One side of the blocking block is fixedly connected to a connecting rod. One end of the connecting rod extends to the top of the wrapping pipe. A driven ring is commonly installed at one ends of the connecting rods. A driving wheel is arranged on the tin liquid outflow housing. The driving wheel is in contact with the driven ring and is connected to an external torque.

[0012] A multi-angle welding method for processing outdoor sports equipment includes the following steps:

[0013] S1. Wind the tin wire around a winding disc, and one end of it sequentially passes through a guiding pipe one and a guiding pipe two until reaching the head position of a welding torch.

[0014] S2. During normal welding, start a vacuum pump to suck the welding fumes into a dust suction pipe, and filter the fumes through a filter screen. The filtered air enters an exhaust pipe and is discharged, and the solid impurities are retained on the filter screen. The two filter screens are respectively located in the filtration housing and the reduction reaction chamber.

[0015] S3. At regular intervals, switch the positions of the two filter meshes so that the filter mesh covered with tin dust enters the reduction reaction chamber. Close the vacuum pump and connect the hydrogen source, and heat the filter mesh with the electric heater. As the temperature rises to 500 - 600 degrees Celsius, the tin-containing oxides start to undergo a reduction reaction, and the generated tin droplets accumulate on the filter mesh and fall into the tin liquid flow pipe;

[0016] S4. After each welding is completed, collect the small particle welding slag and tin droplets and put them into the reduction reaction chamber for reduction reaction. At this time, the tin liquid will flow into the tin liquid outflow shell, and its liquid temperature is maintained by the electric heating wire. After the tin liquid completely covers the bottom inner wall of the tin liquid outflow shell (52), open the blocking block, and the tin liquid will wrap around the surface of the transported tin wire, reducing the oxidation process of the tin wire itself.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, a flue gas recovery device and a reduction reaction chamber are used to reduce the oxides, small particle welding slag, and tin droplets in the fumes generated during tin wire welding. Then, the reduced tin is heated to a liquid state, and together with the recovered flux residues in the fumes, it adheres to the surface of the tin wire. When heated, the tin on the surface will be oxidized first, without damaging the integrity of the original antioxidant coating on the tin wire surface, and the recovered part can be recycled to reduce costs.

Detailed implementation manners

[0026] The technical solution of the present invention will be further described in detail and non - restrictively below in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

[0027] Please refer to Figures 1-6 , the present invention provides a technical solution: A multi - angle welding device for processing outdoor sports equipment, including a robotic arm 1. One end of the robotic arm 1 is installed with a mounting bracket 2. A welding torch 21 is provided on the mounting bracket 2. A fixed seat 3 is fixedly installed on one side of the mounting bracket 2. A telescopic cylinder 31 is installed on one side of the fixed seat 3. The output end of the telescopic cylinder 31 is connected to a wire reel 32. A dust suction pipe 43 is also installed on one side of the mounting bracket 2. The top of the dust suction pipe 43 is installed with a filter housing 4. The top of the filter housing 4 is connected through and communicated with an exhaust pipe 41. One end of the exhaust pipe 41 is provided with a vacuum pump 42. During operation, the welding torch 21 is started for tin wire welding. By starting the telescopic cylinder 31, the position of the wire reel 32 is adjusted to tighten and start transporting the tin wire. The tin - containing dust generated during welding is absorbed through the dust suction pipe 43. The tin - containing dust mainly includes micro - molten tin droplets, tin - containing oxides, and flux residues. The solid dust is intercepted and filtered by the filter housing 4, and the air is pumped into the exhaust pipe 41;

[0028] On the upper and lower sides of the side wall of the fixed seat 3, a first heating housing 33 and a second heating housing 34 are correspondingly installed. A first guiding pipe 331 is connected to the bottom of the first heating housing 33, and a second guiding pipe 341 is connected to the bottom of the second heating housing 34. A driving motor 371 is fixedly installed on one side of the fixed seat 3. The output end of the driving motor 371 is connected to a driving gear 37. A driven gear 351 is correspondingly rotatably installed on the side wall of the fixed seat 3. The driven gear 351 meshes with the driving gear 37. A first squeezing wheel 35 is installed on one side of the driven gear 351. A second squeezing wheel 36 is correspondingly rotatably installed on one side of the fixed seat 3. The second squeezing wheel 36 and the first squeezing wheel 35 are in a matching structure. Before welding the solder wire, preheat it through the first heating housing 33 and the second heating housing 34, so that it is heated with a certain gradient, which is suitable for welding multi-layer circuit boards or complex components. By starting the driving motor 371, the driving gear 37 is driven to rotate, so that the driven gear 351 drives the first squeezing wheel 35 to rotate. As it comes into contact with the solder wire, it will squeeze the solder wire with the second squeezing wheel 36, so that the recycled tin liquid is more evenly coated on the surface of the solder wire;

[0029] On one side of the filtering housing 4, a reduction reaction chamber 5 is provided. A connecting shell 7 is fixedly welded between the filtering housing 4 and the reduction reaction chamber 5. A recovery cover 53 is installed on the top of the reduction reaction chamber 5. One side of the reduction reaction chamber 5 is connected through and through with a hydrogen source 65. A regulating valve 66 is provided at the connection position between the hydrogen source 65 and the reduction reaction chamber 5. An exhaust valve 64 is connected through and through to the top of the reduction reaction chamber 5. After welding is completed, there will be a lot of small particle welding slag and tin drops on the welding workbench. Open the recovery cover 53 and put them into the reduction reaction chamber 5 to carry out the reduction reaction together. When the reduction reaction occurs, open the hydrogen source 65 so that hydrogen is introduced into the reduction reaction chamber 5 for reduction reaction. The water vapor generated by the reduction is discharged through the exhaust valve 64;

[0030] On the corresponding inner side walls of both sides of the filtering housing 4 and the reduction reaction chamber 5, sliding grooves 68 are installed. Sliding blocks 681 are slidably installed in the sliding grooves 68. A filter screen 61 is fixedly installed between the two sliding blocks 681. The number of filter screens 61 is two. The sliding blocks 681 have magnetism. Electromagnets are evenly embedded in the sliding grooves 68, and each electromagnet is electrically connected to an external power supply. When it is necessary to drive the filter screen 61 to move back and forth in the filtering housing 4 and the reduction reaction chamber 5, start the electromagnets from near to far from the sliding block 681 in turn, and attract the sliding block 681 to move, so that the sliding block 681 drives the filter screen 61 to slide horizontally in the sliding groove 68, thereby adjusting the horizontal position of the filter screen 61. During use, always keep one of the filter screens 61 filtering in the filtering housing 4, and the other performing reduction reaction in the reduction reaction chamber 5 without delaying normal work;

[0031] The inner wall of the reduction reaction chamber 5 is correspondingly installed with a mounting rack 62. The outer wall of the mounting rack 62 is slidably installed with an electric heater 63. The top of the mounting rack 62 is installed with an electric push rod 67. The output end of the electric push rod 67 is connected to the electric heater 63. By starting the electric push rod 67, the electric heater 63 is driven to move up and down. When the lower filter screen 61 enters the reduction reaction chamber 5, the electric heater 63 is moved to the lower position. When the upper filter screen 61 enters the reduction reaction chamber 5, the electric heater 63 is moved to the upper position. The temperature of the filter screen 61 is raised to the temperature capable of carrying out the reduction reaction through the heating action of the electric heater 63;

[0032] The bottom of the reduction reaction chamber 5 is connected through a tin liquid flow pipe 51. One end of the tin liquid flow pipe 51 is connected through a tin liquid outflow shell 52. The tin liquid outflow shell 52 is fixed to the fixed seat 3. The wrapping pipe 521 is arranged vertically through the tin liquid outflow shell 52. Electric heating wires 88 are embedded in the inner walls of the tin liquid outflow shell 52 and the tin liquid flow pipe 51. Discharge holes 524 are evenly arranged on the side wall of the wrapping pipe 521. When the tin liquid is reduced, it will flow into the tin liquid outflow shell 52 and flow to the surface of the tin wire through the discharge holes 524, forming a temporary protective layer on its outer wall to protect the antioxidant layer of the tin wire itself from being damaged;

[0033] The wall surface where the discharge holes 524 are located extends inwards to form an accommodation groove 523. A blocking block 56 is slidably installed inside the accommodation groove 523. One side of the blocking block 56 is fixedly connected to a connecting rod 54. One end of the connecting rod 54 extends to the top of the wrapping pipe 521. One ends of the connecting rods 54 are jointly installed with a driven ring 551. A driving wheel 55 is arranged on the tin liquid outflow shell 52. The driving wheel 55 is in contact with the driven ring 551 and is connected to an external torque. When the tin liquid inside the tin liquid outflow shell 52 is insufficient, the blocking block 56 is closed, so that the discharge holes 524 are closed and the tin liquid cannot flow out. When the tin liquid inside the tin liquid outflow shell 52 is sufficient, the blocking block 56 is opened, so that the tin liquid evenly flows into each discharge hole 524 and evenly wraps on the surface of the tin wire. By starting the external torque to drive the driving wheel 55 to rotate, the driven ring 551 is rotated, driving each connecting rod 54 to move, and thus synchronously driving each blocking block 56 to move, uniformly connecting and closing the channels of the tin liquid;

[0034] A multi-angle welding method for processing outdoor sports equipment includes the following steps:

[0035] S1. Wind the tin wire on the winding disc 32, and one end of it sequentially passes through the first guide pipe 331 and the second guide pipe 341 until it reaches the head position of the welding torch 21;

[0036] S2. During normal welding, start the vacuum pump 42 to suck the welding fumes into the suction pipe 43, and filter the fumes through the filter screen 61. The filtered air enters the exhaust pipe 41 and is discharged, while the solid impurities are retained on the filter screen 61. The two filter screens 61 are respectively located in the filter housing 4 and the reduction reaction chamber 5.

[0037] S3. At regular intervals, switch the positions of the two filter screens 61 so that the filter screen covered with tin dust enters the reduction reaction chamber 5. Close the vacuum pump 42 and connect the hydrogen source 65, and make the electric heater 63 heat the filter screen 61. As the temperature rises to 500 - 600 degrees Celsius, the tin-containing oxides start to undergo a reduction reaction, and the generated tin droplets accumulate on the filter screen 61 and fall into the tin liquid flow pipe 51.

[0038] S4. After each welding is completed, collect the small particle welding slag and tin droplets and put them into the reduction reaction chamber 5 for reduction reaction. At this time, the tin liquid will flow into the tin liquid outflow housing 52, and its liquid temperature is maintained by the electric heating wire. After the tin liquid accumulates to completely cover the bottom inner wall of the tin liquid outflow housing (52), open the blocking block 56, and the tin liquid will wrap around the surface of the transported tin wire, reducing the oxidation process of the tin wire itself. The flue gas recovery device and the reduction reaction chamber are used to reduce the oxides, small particle welding slag and tin droplets in the welding fumes generated by tin wire welding, and then heat the reduced tin to a liquid state. Together with the flux residues recovered from the fumes, they adhere to the surface of the tin wire. When heated, the tin on the surface will be oxidized first, without damaging the integrity of the original antioxidant coating on the surface of the tin wire, and the recovered part can be recycled to reduce costs.
