The existing aluminum shell is generally formed by stamping an aluminum plate, but the stamped shell has at least one seam, and the seam needs to be welded to form a closed shell. In addition to a large amount of smoke, the welding operation also contains a large amount of various harmful gases and gasified or atomized chemicals. The main components are harmful gases such as carbon monoxide, hydrocarbons, particulates and carbon smoke. If not treated, it will fly in the air, and it can invade the liver, lungs, cardiovascular system and blood through the respiratory tract.

The support seat is installed in the welding box, and the lifting frame is installed on the support seat and is slidably connected to the support seat. A pneumatic cylinder 1 is installed on the support seat, and the pneumatic end of the pneumatic cylinder 1 is connected to the lifting frame. An extrusion block is installed on the top of the lifting frame, and the storage plate is placed in the lifting frame. The storage plate is connected to the support seat, and the upper end of the storage plate matches the extrusion block.

[0006] During welding, welding is performed in a welding box, and the workpiece is fixed and the weld is aligned by using a welding tool installed in the welding box. After the welding tool fixes the workpiece, the welding tool can slide in the welding box and slide to a position close to the opening and closing door to place the workpiece. Then the moving assembly installed at the top of the inner part of the welding box can carry the welding gun, and the movement of the welding gun is used to weld at the seam. Two different welding tools are installed in the welding box, which are suitable for clamping different workpieces. When the moving assembly drives the welding gun to move for welding, the suction hose installed in the moving assembly works, and the suction hose corresponds to the end of the welding gun.

[0035] When placing a workpiece on the welding tool 4 , there are two embodiments of the welding tool 4 for processing different workpieces.

[0036] Embodiment 1: For a shell with a smaller width, embodiment 1 is used for fixing. The shell sleeve is placed on the storage plate 43, and the weld is placed corresponding to the welding groove 79. After the placement is completed, the pneumatic cylinder 44 is actuated to act on the bottom surface of the lifting frame 42, driving the lifting frame 42 to descend along the sliding block.

[0037] Since the storage plate is installed on the bottom plate 73 of the mounting frame 71 and its position is fixed, the lifting frame 42 drives the extrusion block 45 to descend, and the extrusion block 45 will squeeze the parts on the storage plate 43 until the extrusion groove 78 fits with the storage plate 43, and the upper end of the shell and the storage plate 43 are fit together, so that the seam of the shell corresponds to the welding seam 79, and then the parts can be welded.

[0038] Embodiment 2: For a shell with a larger width, embodiment 2 is used for fixing, and the parts are placed on the storage plate 43, and the joints are also made to correspond to the welding seam 2 87. After the parts are placed, the pneumatic cylinder 1 44 is actuated to act on the lifting plate 81, driving the lifting frame 42 to descend along the lifting rod 83.

[0039] Since the storage plate 43 is installed on the support plate 85 on the mounting seat 8 and the position is fixed, the lifting plate 81 descends, driving the top plate 84 at the top of the side plate 82 and the extrusion block 45 to descend together, and the extrusion block 45 inside the top plate 84 descends until the extrusion block 45 fits with the storage plate 43, and the upper end of the part is squeezed and fixed on the storage plate 43, so that the seam is aligned at the welding seam 87, and then welding can be performed.

[0040] After the workpiece is placed, the opening and closing door 11 is closed, the front end of the welding box 1 is closed, and then the motor 1 24 is actuated, and the moving block 26 threadedly connected thereto is driven to move by the rotation of the screw rod 23, and the moving block 26 drives the lateral block 22 to move, driving the vertical plate 27 and the translation assembly 6 to move to the corresponding position with the welding fixture 4. Then the pneumatic cylinder 2 63 is actuated, driving the welding gun 21 to descend, so that the welding gun 21 corresponds to the welding seam, and then welding the seam is started.

[0041] During welding, the motor 2 62 is operated, and the gear 1 65 on the motor 2 62 is meshed with the rack 66 on the vertical plate 27 to drive the translation plate 61 to move along the sliding block 28 on the vertical plate 27, and then the translation plate 61 drives the welding gun 21 to move along the weld, thereby welding the joint and completing the welding of the workpiece.

[0042] During welding, the suction machine in the suction hose 3 is activated to extract the waste gas generated by the welding gun 21 through the suction hose 3. The extracted waste gas enters the purification frame 51 through the suction hose 3 and is then adsorbed by the adsorption layer in the purification frame 51. The adsorption layer uses activated carbon to adsorb part of the harmful gas and particles in the waste gas. The waste gas after preliminary treatment enters the waste gas incinerator 52. The temperature of the combustible harmful gas in the waste gas incinerator 52 is increased to the reaction temperature, so that oxidation and decomposition occur. The welding of the workpiece and the waste gas treatment during the welding process are completed.
