The No. 1 slot plate 371 is connected to the No. 1 slot plate receiving groove 221, and the No. 1 slot plate 371 slides inside the No. 1 slot plate receiving groove 221. The top of the No. 2 slot plate bearing platform 35 has a No. 2 slot plate 371. 72, the second slot plate 372 is adapted to the second slot plate receiving groove 222, the second slot plate 372 is connected to the second slot plate receiving groove 222, the second slot plate 372 slides inside the second slot plate receiving groove 222, the top of the third slot plate bearing platform 36 has a third slot plate 373, the third slot plate 373 is adapted to the third slot plate receiving groove 223, the third slot plate 373 is connected to the third slot plate receiving groove 223, the third slot plate 373 slides inside the third slot plate receiving groove 223, and the bottom of the inner welded bearing platform 19 has a bottom hydraulic cylinder mounting platform 31. The bottom of the bottom hydraulic cylinder mounting platform 31 has three groups of bottom hydraulic cylinder mounting grooves 32. The three groups of lifting hydraulic cylinders 33 are respectively inserted into the three groups of bottom hydraulic cylinder mounting grooves 32 and fixed. The lifting hydraulic cylinder 33 corresponding to the position of the No. 1 gap plate bearing platform 34 has a hydraulic rod fixedly connected to the No. 1 gap plate bearing platform 34, the lifting hydraulic cylinder 33 corresponding to the position of the No. 2 gap plate bearing platform 35 has a hydraulic rod fixedly connected to the No. 2 gap plate bearing platform 35, and the lifting hydraulic cylinder 33 corresponding to the position of the No. 3 gap plate bearing platform 36 has a hydraulic rod fixedly connected to the No. 3 gap plate bearing platform 36.

[0030] Furthermore, when placing the plate to be welded 8 and the auxiliary welding plate 9, the corresponding lifting hydraulic cylinder 33 is started according to the models of the plate to be welded 8 and the auxiliary welding plate 9, so that the corresponding No. 1 slot plate 371 or No. 2 slot plate 372 or No. 3 slot plate 373 is lifted. At this time, the plate to be welded 8 and the auxiliary welding plate 9 are placed, and the spacing between the plates to be welded 8 and the spacing between the auxiliary welding plates 9 are controlled according to the No. 1 slot plate 371 or No. 2 slot plate 372 or No. 3 slot plate 373. After the plate to be welded 8 is placed, the main welding plate positioning block 38 is driven close to the plate to be welded until the main welding plate positioning block 38 is close. Then, the lifting drive screw 48 is rotated to lower the clamping block 45 until the clamping block 45 is pressed against the surface of the plate to be welded 8 to complete the positioning of the plate to be welded. After the auxiliary welding plates 9 are placed on both sides of the plate to be welded 8, the auxiliary clamp bearing block 24 is moved to the corresponding position so that the auxiliary pressing plate 52 is pressed against the upper part of the auxiliary welding plate 9 to complete the positioning of the auxiliary welding plate 9.

[0031] It should be noted that when the sealing sliding belt 13 slides inside the sealing belt mounting groove 12 and the main welding plate positioning block 38 moves, the internal space of the positioning mechanism mounting groove 11 is moderate and relatively closed, thereby preventing the smoke generated by welding from entering the positioning mechanism mounting groove 11 and contaminating the parts placed inside the positioning mechanism mounting groove 11, thereby increasing the anti-pollution ability of this device and reducing the maintenance frequency of this device.

[0032] It should also be noted that multiple main welding plate positioning blocks 38 can be moved separately, so that when this device is facing the positioning operation of the irregularly shaped plate 8 to be welded, the positioning point of the plate 8 to be welded can be freely adjusted, thereby increasing the positioning ability of this device facing various models of plates 8 to be welded.

[0033] It should also be noted that auxiliary welding plates 9 are placed on both sides of the plate to be welded 8. The auxiliary welding plate 9 on one side is an arc starting plate, and the auxiliary welding plate 9 on the other side is an arc exit plate, so that the initial welding and the final welding both fall on the auxiliary welding plates 9, so that the arc is more stable when the plasma welding head 18 welds the plate to be welded 8, reducing the weld nodules, arc pits, etc. generated in the plate to be welded 8 during the welding process, and the welding effect is good.

[0034] The sealing sliding belt 13 slides smoothly in the positioning mechanism mounting groove 11, so that the multiple main welding plate positioning blocks 38 can independently fine-tune their positions to fit the irregular contours of the plates; after the positioning screws 41 are fixed, the clamping block 45 cooperates with the pressure adaptation of the lifting and driving screw 48 to apply uniform pressure to areas of different thicknesses, thereby significantly improving the positioning accuracy. This is especially suitable for arc-shaped and stepped display arm plates, reducing the time consumption for positioning and solving the problem of positioning deviation of complex curved plates by traditional positioning devices.

[0035] The cooling liquid circulates in the cooling pipe 26 to reduce the surface temperature of the waste collection cloth 27, which not only condenses the metal vapor, but also conducts it to the bottom of the plate to be welded 8 through the main bearing platform 1, forming a "hot on top and cold on the bottom" temperature gradient, which inhibits the warping deformation of the plate due to the high temperature of welding; the negative pressure drainage of the side exhaust pipe 30 and the internal negative pressure groove 20 makes the hot air flow generated by welding flow in an orderly manner along the surface of the waste collection cloth 27, taking away the excess heat in the welding area, and avoiding uneven weld width caused by local overheating; the sealing sliding belt 13 closes the positioning mechanism installation groove 11, preventing hot smoke from entering the main bearing platform, and avoiding the influence of thermal expansion and contraction on the accuracy of the positioning components in the traditional device. The welding deformation of the present invention is reduced by 60%, and the surface roughness Ra value of the weld is reduced from 3.2μm to 1.6μm, which significantly improves the structural strength of the computer display arm.
