[0022] This utility model provides a laser welding device for a TV back panel, comprising a cabinet. The cabinet is equipped with a first X-axis sliding plate 1, a second X-axis sliding plate 2, a left front laser welding positioning mechanism 3, a left rear positioning mechanism 4, a right front laser welding positioning mechanism 5, and a right rear positioning mechanism 6. The first X-axis sliding plate 1 and the second X-axis sliding plate 2 are slidably connected to the top of the cabinet along the X-axis direction. The left front laser welding positioning mechanism 3 and the right front laser welding positioning mechanism 5 each include a first support 30, a front positioning mechanism 31 disposed on the first support 30, an upper laser welding mechanism 32 disposed on the upper side of the first support 30, and a lower laser welding mechanism 33 disposed on the lower side of the first support 30. The first support 30 of the left front laser welding positioning mechanism 3 and the right front laser welding positioning mechanism 5 are slidably connected to the first X-axis sliding plate 1 and the second X-axis sliding plate 2 respectively along the Y-axis direction.

[0023] Its working principle is as follows: the assembled TV back panel is placed between the front positioning mechanism 31 of the left front laser welding positioning mechanism 3, the front positioning mechanism 31 of the right front laser welding positioning mechanism 5, the left rear positioning mechanism 4, and the right rear positioning mechanism 6 to position the four sides of the TV back panel. The upper laser welding mechanism 32 of the left front laser welding positioning mechanism 3 and the right front laser welding positioning mechanism 5 can perform laser welding operations on the inner side of the splicing seam on the left front and right front sides of the TV back panel, respectively. The lower laser welding mechanism 33 of the left front laser welding positioning mechanism 3 and the right front laser welding positioning mechanism 5 can perform laser welding operations on the outer side of the splicing seam on the left front and right front sides of the TV back panel, respectively. Multiple welding operations can be performed on multiple parts of the TV back panel at the same time, effectively improving processing efficiency. By adjusting the X-axis orientation of the first X-axis slide plate 1 and the second X-axis slide plate 2 on the cabinet, the distance between the two first supports 30 and the two second supports 40 can be adjusted. By adjusting the Y-axis orientation of the first supports 30 and the second supports 40 on the first X-axis slide plate 1 and the second X-axis slide plate 2, the distance between the first supports 30 and the second supports 40 can be adjusted to adapt to the positioning and welding processing needs of TV back panels of different sizes, thus improving applicability.

[0024] Based on the above embodiments, the front positioning mechanism 31 includes a front support plate 310 disposed on the top of the first support 30, a plurality of first side pressing mechanisms 311 disposed on the first support 30, and a plurality of first upper pressing mechanisms 312 disposed on the first support 30; the left rear positioning mechanism 4 and the right rear positioning mechanism 6 each include a second support 40, a rear support plate 41 disposed on the top of the second support 40, a plurality of second side pressing mechanisms 42 disposed on the second support 40, and a plurality of second upper pressing mechanisms 43 disposed on the second support 40. The second supports 40 of the left rear positioning mechanism 4 and the right rear positioning mechanism 6 are slidably connected to the first X-axis sliding plate 1 and the second X-axis sliding plate 2 along the Y-axis direction, respectively. When positioning the TV back panel, first place the TV back panel between the front support plate 310 of the left front laser welding positioning mechanism 3, the front support plate 310 of the right front laser welding positioning mechanism 5, the rear support plate 41 of the left rear positioning mechanism 4, and the rear support plate 41 of the right rear positioning mechanism 6. Then, the sides of the TV back panel are held in place by the first side clamping mechanism 311 and the second side clamping mechanism 42 to ensure that the TV back panel is in an accurate position. Then, the edges of the TV back panel are pressed down by the first upper clamping mechanism 312 and the second upper clamping mechanism 43 to prevent the TV back panel from tilting up, thus achieving effective positioning of the TV back panel.

[0025] Based on the above embodiments, the first support 30 includes a base plate 300, a top plate 301, and pillars 302 fixedly connected between the four sides of the base plate 300 and the top plate 301.

An upper laser welding mechanism 32 and a lower laser welding mechanism 33 are respectively disposed on the base plate 300 and the top plate 301.

The upper laser welding mechanism 32 performs welding processing on the inner side of the weld seam of the TV back panel, while the lower laser welding mechanism 33 can perform welding processing on the outer side of the weld seam of the TV back panel through the processing window 301a.

When the X-axis linear drive device 320, the Y-axis linear drive device 321, and the Z-axis linear drive device 322 are working, they can drive the laser welding head 323 to move in the X-axis, Y-axis, and Z-axis respectively, so that the laser welding head 323 can perform welding operations on the splice.

[0027] Based on the above embodiments, the X-axis linear drive device 321, the Y-axis linear drive device 320, and the Z-axis linear drive device 322 are all lead screw slides, which have good working stability.

[0029] Based on the above embodiments, a braking mechanism 7 is provided on the first X-axis sliding plate 1, the second X-axis sliding plate 2, the first support 30, and the second support 40. The braking mechanism 7 includes a mounting plate 70, an internal threaded sleeve 71 that passes through the mounting plate 70, a longitudinal adjusting screw 72 connected to the internal threaded sleeve 71, and a braking pressure plate 73. The bottom end of the longitudinal adjusting screw 72 is provided with a T-shaped connecting end 720, and the top of the braking pressure plate 73 is provided with a T-shaped groove 730 that matches the T-shaped connecting end 720. The T-shaped connecting end 720 is movably disposed in the T-shaped groove 730. Longitudinal guide rods 74 are provided on both sides of the braking pressure plate 73. A guide sleeve 75 corresponding to the longitudinal guide rod 74 is provided through the mounting plate 70, and the longitudinal guide rod 74 is connected to the guide sleeve 75. Rotating the longitudinal adjusting screw 72 can move the longitudinal adjusting screw 72 up and down. When it is necessary to adjust the position of the first X-axis slide plate 1, the second X-axis slide plate 2, the first support 30, and the second support 40, loosen the longitudinal adjusting screw 72 to adjust the position of the first X-axis slide plate 1, the second X-axis slide plate 2, the first support 30, and the second support 40. After the adjustment is completed, tighten the longitudinal adjusting screw 72 to prevent the first X-axis slide plate 1, the second X-axis slide plate 2, the first support 30, and the second support 40 from moving.
