Description

Technical Field

[0001] The present invention relates to the field of laser welding, and more specifically, to a laser welding device for new energy automobile parts. Background Art

[0002] Laser welding is an efficient and precise welding technology that is widely used in various parts in the automotive manufacturing industry, including headlight housings, instrument panel components, electrical boxes, and air filters. Laser welding uses a high-energy laser beam to locally heat the material, melting the material at the contact point and quickly cooling it to form a strong welded joint.

[0003] First, clean the surface of the plastic electrical box to be welded to ensure that there is no dust, grease or other contaminants. Align and fix the two plastic electrical boxes to be welded together, use a clamp to maintain stability, and use the laser welding equipment to focus the laser beam on the welding area. The laser beam will penetrate the upper plastic, melt the lower plastic, and cause the upper plastic to begin to melt through heat conduction. After removing the laser beam, the melted plastic cools rapidly to form a solid welded joint.

[0004] However, when using laser welding equipment, the laser beam is first precisely focused on the area to be welded. The strong energy of the laser beam can penetrate the upper plastic layer and directly act on the lower plastic layer, causing it to melt rapidly. At the same time, due to the effect of heat conduction, the upper plastic layer will also begin to melt, thereby achieving effective welding of the two layers of plastic. However, if the plastic electrical box is in a sealed state during the welding process, the smoke generated during the laser welding process may gather in the box and may cover the electronic components in the box. The smoke generated during the welding process may contain volatile organic compounds (VOCs), particulate matter and other chemicals, which may affect the surface or internal components of electronic parts to a certain extent, and have an adverse effect on some particularly sensitive electronic components. For this reason, we propose a laser welding device for new energy vehicle accessories. Summary of the invention

DETAILED DESCRIPTION

[0031] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] like Figure 1 - Fig. 9As shown, a laser welding device for new energy automobile parts comprises: a laser welding machine chassis 11, a laser welding part 12 for welding a plastic automobile parts box body is arranged inside the laser welding machine chassis 11, a laser welding area of ​​the laser welding part 12 is provided with a lower pressing frame 13 for displaying a working area, the surface of the plastic parts to be welded is cleaned to ensure that there is no dust, grease or other pollutants, and then two plastic parts to be welded are aligned and fixed together, and a plastic part positioning mechanism 2 is usually used to maintain stability, and the laser beam is focused to the welding area by the laser emission head of the laser welding part 12 for heating and welding;

[0033] A plastic part positioning mechanism 2 is arranged below the pressing frame 13, which is used to limit the tightness of the upper and lower parts of the plastic automobile parts box before welding. The plastic part positioning mechanism 2 includes a supporting seat 21, a limiting member 23 is arranged above the supporting seat 21, a limiting groove 25 is provided at the center of the limiting member 23, a plurality of side return grooves 251 are arranged on the inner wall of the limiting groove 25, a clamping column 27 forming a telescopic structure with the limiting member 23 is penetrated in the side return groove 251, and a negative pressure smoking mist member 3 is fixedly arranged on the top of the limiting member 23, which is used to suck out the smoke generated in the box from the welding seam of the plastic automobile parts box body;

[0034] After the upper and lower parts of the plastic automobile parts box body are butt-jointed, they are placed on the support seat 21, and the parts to be welded are clamped by extending the clamping columns 27 around the limit groove 25, and a plurality of clamping columns 27 are extended until they are against the plastic automobile parts box body. The clamping columns 27 have different telescopic lengths according to the shapes of the plastic automobile parts box bodies, which is conducive to the application of parts boxes of various specifications. The height at which the staff places the plastic automobile parts box body on the support seat 21 requires a plurality of clamping columns 27 to be just aligned with the welding seam of the plastic automobile parts box body, and then the same force is applied to the upper and lower parts of the parts box by telescoping a plurality of clamping columns 27, which is conducive to ensuring the stability of the upper and lower parts of the parts box.

[0035] The negative pressure smoking mist element 3 includes a soft rubber plate 31 fixedly connected to the top of the clamping column 27, and the size of the soft rubber plate 31 matches the size of the side return groove 251. The soft rubber plate 31 is provided with a plurality of suction holes 34 along the welding seam direction of the plastic automobile component box body;

[0036] When several clamp columns 27 are pressed against the welding seam of the plastic automobile part box body, the soft rubber plate 31 also covers the welding seam of the plastic automobile part box body. On the one hand, the clamping area of ​​the part box is increased, making the upper and lower parts of the part box more stable before welding. On the other hand, when the air pump machine 22 works to provide extended gas power for several clamp columns 27, the air suction of the air pump machine 22 causes several suction holes 34 of the soft rubber plate 31 to vigorously suck air out from the welding seam of the plastic automobile part box body, so that laser welding is performed while smoke is sucked out from the unwelded gap, which is conducive to timely discharge of smoke from the working area, avoiding its accumulation in the electrical box, and reducing the pollution of harmful substances to the interior of the electrical box and electronic components.

[0037] Height-adjusting columns 26 are provided inside the four corners of the limiting member 23, and the bottom ends of the height-adjusting columns 26 are fixedly connected to the bracket seat 21, and the limiting member 23 slides up and down along the four height-adjusting columns 26 to adjust the center line of the soft rubber plate 31 to align with the welding seam of the plastic automobile part box body. When the plastic automobile part box body is placed in the limiting groove 25, the staff manually presses down or lifts up the limiting member 23 to adjust the height of the limiting member 23, which is suitable for plastic automobile part boxes of different sizes.

[0038] The plastic part positioning mechanism 2 also includes an air pump machine 22 installed inside the support seat 21, and the air outlet end of the air pump machine 22 is connected to an air outlet pipe 222, and the end of the air outlet pipe 222 away from the air pump machine 22 is connected to an air outlet diversion pipe 224, and the output end of the air outlet diversion pipe 224 is connected to a plurality of air outlet main pipes 226, and the plurality of air outlet main pipes 226, the air outlet diversion pipes 224 and the air outlet pipe 222 are interconnected. When the air pump machine 22 is working, the air is injected into the air outlet diversion pipe 224 through the air outlet pipe 222 for collection, and then the air is diverted to the plurality of air outlet main pipes 226 through the air outlet diversion pipe 224, and then the air is collected into the air collecting box 271 by the plurality of air outlet main pipes 226. After multiple diversions and collections, it is beneficial to buffer the air and ensure that the air intake of the plurality of clamp columns 27 is the same.

[0039] One end of several air outlet main pipes 226 away from the air outlet diversion pipe 224 is connected to an air collecting box 271, and the output ports of several air outlet main pipes 226 are interconnected with the interior of the air collecting box 271. The air collecting box 271 is fixedly connected to the limiter 23, which is used to balance the stability of the air supply of the air collecting box 271 to the telescopic inner tube 272. When the air is collected in the air collecting box 271, the air flows freely and evenly into the several telescopic inner tubes 272.

[0040] The output end of the air collecting box 271 is connected to a plurality of telescopic inner tubes 272, and the telescopic inner tubes 272 penetrate the clamp column 27. A piston 273 is fixedly provided at one end of the telescopic inner tube 272 away from the air collecting box 271, and a plurality of reset belts 274 are fixedly provided at the outer ring of the piston 273 away from the telescopic inner tube 272. After the air flows into the telescopic inner tube 272, it flows out from the piston 273. As the amount of air increases, the clamp column 27 is pushed to slide and extend until it is tightly pressed against the welding seam of the plastic automobile parts box body. The clamp column 27 is telescopic according to the different shapes of the plastic automobile parts box body. Different lengths are conducive to the application of parts boxes of various specifications, and the staff places the plastic automobile parts box body on the support seat 21 at a height that requires several clamping columns 27 to be just aligned with the welding seam of the plastic automobile parts box body. Then, the same force is applied to the upper and lower parts of the parts box through the extension and contraction of several clamping columns 27, which is conducive to ensuring the stability of the upper and lower parts of the parts box. Finally, when the welding is completed, the air pump machine 22 stops working, and the air in the clamping column 27 cannot be replenished and discharged freely. Under the pull of several reset belts 274, the extended clamping column 27 is pulled back.

[0041] The air inlet end of the air pump 22 is connected to an air inlet pipe 221, and the end of the air inlet pipe 221 away from the air pump 22 is connected to an air inlet diverter pipe 223, and a plurality of smoke ducts 225 are fixedly provided on the upper wall of the air inlet diverter pipe 223, and the plurality of smoke ducts 225 are interconnected with the air inlet diverter pipe 223. When the air pump 22 starts to work, it needs to inhale air, and the air is inhaled by a plurality of air inhalation holes 34, and a negative pressure is formed by the plurality of air inhalation holes 34, and then enters the telescopic tube 275, and finally is collected by a plurality of smoke ducts 225 into the air inlet diverter pipe 223, and finally enters the air pump 22 through the air inlet pipe 221.

[0042] A plurality of smoking ducts 225 are sequentially passed through the main air outlet pipe 226, the air collecting box 271, the telescopic inner tube 272 and the piston 273, and one end of the smoking duct 225 away from the air inlet diversion pipe 223 is connected with a telescopic tube 275 which is interconnected, and the telescopic tube 275 is interconnected with a plurality of air suction holes 34. The telescopic tube 275 is a corrugated tube and does not affect the circulation of air when the clamp column 27 is extended. The air inlet pipe 221, the air outlet pipe 222, the smoking duct 225 and the main air outlet pipe 226 in the present application are all elastic tubes, which do not affect the rise and fall of the limit member 23.

[0043] A main support plate 32 is fixedly provided on one side of the soft rubber plate 31 close to the side return groove 251, and one end of the main support plate 32 close to the clamp column 27 is fixedly connected to the clamp column 27, and a plurality of elastic bending plates 33 are fixedly provided on the upper and lower sides of the main support plate 32, and the main support plate 32 and the plurality of elastic bending plates 33 form a fishbone shape. The fishbone-shaped main support plate 32 and the plurality of elastic bending plates 33 are beneficial to increase the hardness of the soft rubber plate 31, and prevent the occurrence of pressure differences on the automobile parts box caused by facing each other under a negative pressure state. Through the suction of the air pump machine 22, the plurality of suction holes 34 of the soft rubber plate 31 vigorously suck air out from the welding seam of the plastic automobile parts box body, so that smoke is sucked out from the unwelded gap while laser welding is performed, which is beneficial to timely discharge the smoke from the working area, avoid its accumulation in the electrical box, and reduce the pollution of harmful substances to the interior of the electrical box and electronic components.

[0044] A pressure relief head 28 is fixedly disposed at the center of the soft rubber plate 31 , and the center of the pressure relief head 28 is aligned with the center of the clamp column 27 , and the interior of the pressure relief head 28 is a hollow structure.

[0045] An arc-shaped counter-support arm 36 is fixedly provided on one side of the pressure relief head 28 away from the soft rubber plate 31. Two pull wires 35 are fixedly provided at the center of the counter-support arm 36. The two pull wires 35 respectively penetrate the main support plate 32 and a plurality of elastic bending plates 33 on both sides of the clamp column 27. The relaxation of the pull wires 35 is used to release the plurality of elastic bending plates 33 to drive the soft rubber plate 31 to completely merge. After the clamp column 27 is pressed against the automobile parts box, the pressure relief head 28 is squeezed, and at the same time, the counter-support arm 36 is squeezed to relax the two pull wires 35. When the two pull wires 35 are relaxed, the plurality of elastic bending plates 33 can be completely bent instantly under the elastic force, just like a children's toy "snap bracelet", and drive the soft rubber plate 31 to bend, so that the soft rubber plate 31 can be more closely fitted to the welding seam of the plastic automobile parts box body.

[0046] When the plastic automobile parts box has an outer corrugated welding eave, the soft rubber plate 31 is bent and merged to form an inverted concave shape to wrap the outer corrugated welding eave, which is beneficial to the stability of the outer corrugated welding eave and is more conducive to sucking out smoke from the gap. The pressure relief head 28 is squeezed to form a flat screw head shape, which also has a certain wrapping effect on the outer corrugated welding eave and is more stable.

[0047] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
