Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and more specifically, to a metal welding equipment for the production of massage chairs. Background Art

[0002] Massage chairs use mechanical rolling force and mechanical extrusion for massage. Manual massage can dredge meridians, promote blood circulation, and maintain the balance of yin and yang in the body. Therefore, after massage, one can feel relaxed muscles, flexible joints, be invigorated, eliminate fatigue, which is important for maintaining good health. For people who sit for long hours at work and study, massage can make blood circulation smooth, relieve back pain and prevent diseases, improve sleep quality, relieve overall fatigue, improve posture and exercise a healthy body.

[0003] When producing massage chairs, welding devices are needed to weld and fix the metal components. For example, the patent with the publication number CN215699140U discloses a welding equipment for metal processing, which includes a protective housing, a welding head, and a mounting plate. The mounting plate is installed on the bottom surface of the inner wall of the protective housing, and the welding head is installed at the upper end inside the protective housing. There are mounting frames on both the left and right sides above the mounting plate. There are two clamping plates inside the mounting frames, and the clamping plates are used to clamp the welding parts. There is a sliding component between the mounting frames and the mounting plate, and the sliding component is used to drive the two mounting frames to approach or move away from each other. There are side plates at both the left and right ends above the mounting plate, and the side plates are located outside the mounting frames. Electric push rods are installed on both the left and right surfaces of the inner wall of the protective housing, and the power output ends of the electric push rods are connected to the outer surfaces of the adjacent side plates. In the present invention, the clamping plates and the side plates are used to limit the metal to be welded, and the double limit effectively prevents the metal to be welded from shifting and affecting the welding quality. However, after the welding head of the existing welding device has been welding with flux for a long time, the welding head is prone to oxidation. After oxidation, it is not easy to adhere to the flux and affects the welding of metal components, and manual treatment of the welding head is required, which is rather troublesome.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. A metal welding device for massage chair production proposed by the present invention. The existing welding device relies on manual operation for the oxidation treatment of the welding head. However, through the setting of the processing component in the present invention, when using the electric linear module to move the welding head to align with the installation housing of the processing component, and the lifting cylinder pushes the welding head down to insert into the access port of the installation housing, when the driving rotating shaft drives the installation housing to rotate, the vertically stacked abrasive papers and wedge-shaped grinding blocks inside it grind the outer wall of the lower end of the welding head to remove the oxidation substances and sundries on its surface, realizing the automatic oxidation treatment of the welding head. After a single abrasive paper is used up, it is drawn out from the paper extraction hole, and the pusher pushes a new abrasive paper to fit the wedge-shaped grinding block based on the reset spring for replenishment, enabling the abrasive paper to continuously grind the welding head, which is convenient and practical.

[0020] 2. A metal welding device for massage chair production proposed by the present invention. The existing welding device has a poor treatment effect on dust and fumes. However, through the setting of the air extraction component, the alkali liquid storage chamber and the gas storage tank in the present invention, the air extraction pipe uses the air extraction cylinder and the air guide pipe to transfer the dust and fumes in the protective box to the separation box. After separating the dust and fumes by using the filter cloth sleeve, the fumes are introduced into the alkali liquid storage chamber to react with the alkali liquid to remove substances such as nitrogen oxides therein. Subsequently, the escaped carbon monoxide gas is introduced into the gas storage tank through the air outlet valve pipe for collection. After the gas collection is completed, the dust is discharged from the ash discharge valve pipe at the bottom of the separation box for treatment, realizing the effective classified and harmless treatment of welding dust and fumes, which is energy-saving and environmentally friendly.

[0021] 3. A metal welding device for the production of massage chairs proposed by the present invention. Although existing welding devices can adjust the positions of metal components, they cannot ensure the welding precision of metal components. Through the setting of the positioning component, the present invention can adaptively bind metal components with different thicknesses at both ends within a certain range by means of the adaptive adjustment of the positioning support plate, fixed binding ropes and electric push rods, and compare the images of the welding ends of metal components through an ultrasonic imaging probe. The intelligent controller controls the lifting and lowering of the lifting seat to adjust and calibrate a single metal component, fully ensuring the welding precision of metal components.

[0036] Please refer to Figure 1 and Figure 2 , a metal welding device for the production of massage chairs, including a frame base 1 and a welding table 2 fixedly connected to the top of the frame base 1. A protection box 3 is fixedly connected to the top of the welding table 2.

The top end of the protection box 3 is fixedly connected with a vacuum pumping device 6, and the air inlet end of the vacuum pumping device 6 is communicated with the protection box 3.

[0037] In order to solve the problem that the welding head 74 of the welding device is prone to oxidation after long-term use, which affects the welding of metal components and requires repeated manual treatment, please refer to Figures 1 - 6 , the following preferred technical solutions are provided:

[0038] A welding mechanism 7 is fixedly connected between the inner walls on both sides of the protection box 3, and a positioning mechanism 8 is fixedly connected to the upper end of the bottom plate of the protection box 3. The welding mechanism 7 is suspended above the positioning mechanism 8. A camera is arranged on the inner wall of the back plate of the protection box 3, and the camera is electrically connected to the display 5; the welding mechanism 7 includes an electric linear module 71 fixedly connected between the inner walls on both sides of the protection box 3 and a lifting cylinder 72 arranged on the outer wall of the slider of the electric linear module 71. A welding machine main body 73 is fixedly connected to the bottom of the lifting cylinder 72, and a welding head 74 is fixedly connected to the bottom of the welding machine main body 73. The welding head 74 is suspended above the positioning mechanism 8, and a processing component 75 is fixedly connected to the outer wall of the electric linear module 71 on one side of the welding machine main body 73.

[0039] The processing component 75 includes an L-shaped support plate 751 fixedly connected to the outer wall of one end of the electric linear module 71 and a driving rotating shaft 752 movably arranged on the top of the end of the bottom plate of the L-shaped support plate 751. A mounting shell 753 is fixedly connected to the top of the driving rotating shaft 752. The mounting shell 753 has a hollow structure, and an access port 754 is opened on one side outer wall thereof. The access port 754 extends to the top of the mounting shell 753, and wedge-shaped grinding blocks 755 are fixedly connected to the inner walls on both sides of the mounting shell 753 adjacent to the access port 754. A storage groove 757 is fixedly connected to the outer wall of the mounting shell 753 away from the access port 754. The storage groove 757 is communicated with the mounting shell 753. Grinding sandpapers 756 are vertically stacked inside the storage groove 757, and the grinding sandpapers 756 extend into the mounting shell 753. The grinding sandpaper 756 closest to the access port 754 is arranged in contact with the wedge-shaped grinding block 755, and a pushing member 758 is arranged at the top of the storage groove 757. The lower end of the pushing member 758 extends into the storage groove 757 to press against the stacked grinding sandpapers 756. Suction holes 759 are opened on the outer walls on both sides of the mounting shell 753, and sealing plugs are movably clamped inside the suction holes 759.

[0040] The driving member 758 includes guide rods 7581 fixedly connected to both ends of the side wall of the mounting housing 753. The guide rods 7581 are symmetrically arranged with respect to the storage groove 757. A movable support plate 7582 is movably penetrated through the outer wall of the guide rod 7581. A return spring 7583 is wound around the guide rod 7581 between the movable support plate 7582 and the mounting housing 753. Both ends of the return spring 7583 are fixedly connected to the movable support plate 7582 and the mounting housing 753 respectively. The top end of the movable support plate 7582 is fixedly connected to the bottoms of both ends of the transverse dial 7584. The transverse dial 7584 is horizontally suspended across the top of the storage groove 757. A fixed hanging rod 7585 is fixedly connected to the lower end of the transverse dial 7584. The lower end of the fixed hanging rod 7585 extends into the storage groove 757. Pressure plates 7586 are uniformly fixedly connected to both outer walls of the fixed hanging rod 7585. The pressure plates 7586 are abutted against the abrasive paper 756 in the storage groove 757. After the abrasive paper 756 in contact with the wedge-shaped grinding block 755 is used, the used abrasive paper 756 is drawn out of the mounting housing 753 through the paper extraction hole 759. The stretched return spring 7583 drives the movable support plate 7582 and the transverse dial 7584 to move towards the mounting housing 753. The transverse dial 7584 uses the fixed hanging rod 7585 and the pressure plates 7586 at the bottom to push the stacked abrasive papers 756 to continue to fit the wedge-shaped grinding block 755, realizing the automatic replenishment of the new abrasive paper 756, so as to continuously perform deoxidation treatment on the welding head 74.

[0041] Specifically, when the welding head 74 is oxidized, the electric linear module 71 moves the welding machine main body 73 and the welding head 74 above the mounting housing 753. Then, the lifting cylinder 72 moves the welding head 74 downward so that it is inserted into the access port 754 of the mounting housing 753. The lower end of the welding head 74 is respectively in contact with the wedge-shaped grinding block 755 and the abrasive paper 756. Then, the driving rotating shaft 752 is started to drive the mounting housing 753 to rotate. When the mounting housing 753 rotates, it pushes the wedge-shaped grinding block 755 and the abrasive paper 756 to rotate in contact with the outer wall of the lower end of the welding head 74. When rotating, the wedge-shaped grinding block 755 and the abrasive paper 756 grind the outer wall of the lower end of the welding head 74, removing the oxidation substances and sundries on the outer wall of the lower end of the welding head 74, realizing the automatic grinding treatment of the oxidation of the welding head 74, so that the welding head 74 can adhere to the soldering flux to weld the metal parts, avoiding the trouble of manual grinding and being convenient to use.

[0042] In order to achieve the welding accuracy of metal parts during welding, as Figure 1 、 Figure 3 and Figures 7 - 9 shown, the following preferred technical solutions are provided:

[0043] The positioning mechanism 8 includes a protective backing plate 81 fixedly connected to the bottom plate of the protective box 3 and lifting seats 82 fixedly connected to both sides of the upper end of the protective backing plate 81. A positioning support plate 83 is fixedly connected to the top of the lifting seat 82. Anti-slip bumps 84 are evenly spaced at the top end of the positioning support plate 83. A number of fixed binding ropes 85 are fixedly connected at equal intervals to the top of one end of the positioning support plate 83. The other ends of the fixed binding ropes 85 all pass through the edge of the other end of the positioning support plate 83 movably. The end of the fixed binding rope 85 extends below the positioning support plate 83, and a connecting suspension plate 86 is fixedly connected to its bottom. Electric push rods 87 are fixedly connected to the top edges of both ends of the connecting suspension plate 86. The top end of the electric push rod 87 is fixedly connected to the edge of the lower end of the positioning support plate 83.

[0044] An ultrasonic imaging probe 88 is fixedly connected to the middle of the top end of the positioning support plate 83 between the lifting seats 82.

The lifting seat 82 includes an installation bottom box 821 fixedly connected to the top of the positioning support plate 83 and an H-shaped frame 822 movably clamped between the inner walls of the installation bottom box 821. The support plates on both sides of the H-shaped frame 822 are fixedly connected to the positioning support plate 83. An adjusting lead screw 823 is movably penetrated through the middle of the bottom plate of the H-shaped frame 822. Support elastic members 824 are fixedly connected to the lower ends of the bottom plates of the H-shaped frame 822 on both sides of the adjusting lead screw 823.

[0045] Specifically, place the two metal components of the massage chair on the upper end of the positioning support plate 83 respectively, and place the metal components below the fixed binding ropes 85 so that their welding ends extend into the gap of the positioning support plate 83. After the welding heads 74 of the metal components are on the same horizontal line, start the electric push rod 87 to extend and push the connecting suspension plate 86 to move downward away from the positioning support plate 83. The connecting suspension plate 86 stretches and tightens the fixed binding ropes 85 to bind the metal components. When the sizes of both ends of the metal components are different, the electric push rod 87 can be extended by different lengths, and the fixed binding ropes 85 are in different tightening degrees to bind the metal components so as to adapt to the shaped metal components. After the metal components are bound, the ultrasonic imaging probe 88 detects the welding ends of the two bound metal components. The images of the welding ends of the metal components are displayed on the display 5 for coaxial comparison. The intelligent controller 4 judges whether the welding ends of the two metal components are aligned. If they are not aligned, start the lifting seat 82 to lift the positioning support plate 83 and the metal components on one side of the protective backing plate 81 to accurately align them with the metal components on the other side, fully ensuring the welding precision of the metal components, which is convenient and practical.

A wind attracting ball 1137 is fixedly connected to the bottom of the elastic suspension cord 1136. A first connecting cord 1138 is fixedly connected to one side of the bottom of the wind attracting ball 1137. The other end of the first connecting cord 1138 is fixedly connected to the inner wall at the bottom of the filter cloth sleeve 1135. A flow retardation baffle 1139 is fixedly connected to the lower end of the top plate of the separation box 113 adjacent to the outside of the sealing plate 1134. The flow retardation baffle 1139 is suspended outside the sealing plate 1134. And a movable connection seat 11310 is fixedly connected to the inclined bottom plate of the separation box 113 at the lower end of the flow retardation baffle 1139. A vibrating rod 11311 is fixedly connected to the outer wall of one side of the movable ball at the top of the movable connection seat 11310. A second connecting cord 11312 is fixedly connected to the outer wall of one side of the vibrating rod 11311. The other end of the second connecting cord 11312 is fixedly connected to the bottom of the wind attracting ball 1137.

[0051] When the end of the filter cloth sleeve 1135 hangs vertically at the port of the through hole of the sealing plate 1134, the elastic suspension rope 1136 is vertically suspended in the through hole of the sealing plate 1134. At this time, the second connecting rope 11312 is in a relaxed state, and the end of the vibrating rod 11311 leans against the inclined bottom plate on the other side of the bottom of the separation box 113.

[0052] The wind-catching ball 1137 includes a spherical shell 11371 fixedly connected to the elastic suspension rope 1136. Wind-catching grooves 11372 are evenly spaced on the outer wall of the spherical shell 11371. The sizes and depths of the respective wind-catching grooves 11372 are different, and the spherical shell 11371 is a hollow structure, and a counterweight ball 11373 is movably placed inside it. After the dust-laden flue gas enters the separation box 113, the airflow blows the filter cloth sleeve 1135 to bulge. The flow-attenuating baffle 1139 blocks and circulates the airflow, and the dust is intercepted and separated by the filter cloth sleeve 1135. Part of it directly falls onto the bottom plate of the separation box 113 for accumulation. After the filter cloth sleeve 1135 bulges, it blows the pull rope of the wind-catching ball 1137, i.e., the elastic suspension rope 1136, to swing in an indefinite direction. When the wind-catching ball 1137 swings, the second connecting rope 11312 pulls the vibrating rod 11311 to move slowly in an indefinite direction. The vibrating rod 11311 stirs the accumulated dust to prevent precipitation and compaction. After the air extraction ends, the wind-catching ball 1137 drives the filter cloth sleeve 1135 to droop and vibrate by its own weight, and the dust adhered to the outer wall of the filter cloth sleeve 1135 is automatically shaken off by the vibration of the filter cloth sleeve 1135, realizing the automatic shaking and cleaning of the filter cloth sleeve 1135 after each air extraction ends, and avoiding excessive adhesion of dust to the filter cloth sleeve 1135, which affects air permeability.

[0053] Specifically, when harmful dust-laden flue gas is generated during welding inside the protective box 3, the suction pipe 115 uses the suction cylinder 111 and the guide pipe 112 to suck the harmful dust-laden flue gas generated during welding inside the protective box 3, and transfers it to the separation box 113. After the dust is intercepted and separated by the filter cloth sleeve 1135, it falls on the inclined bottom plate of the separation box 113 below the flow-attenuating baffle 1139. Then, the flue gas moves through the ventilation port 1132 to the other side of the partition plate 1131 and is introduced into the alkali liquid storage chamber 9 along the suction pipe 115. The flue gas is introduced from the bottom of the alkali liquid in the alkali liquid storage chamber 9 for dispersion. Substances such as nitrogen oxides and ozone in the welding flue gas react with the alkali liquid and are absorbed. After the nitrogen oxides are absorbed, carbon monoxide gas escapes from the alkali liquid. After the carbon monoxide gas escapes, it is introduced into the gas storage tank 13 through the air outlet valve pipe 12 for collection, and the carbon monoxide is used as a reducing agent. After the gas collection ends, the dust is discharged from the ash discharge valve pipe 114 at the bottom of the separation box 113 for treatment, realizing the effective classified and harmless treatment of welding dust-laden flue gas, energy conservation and environmental protection.
