A movable seat 42 is fixedly installed on the top surface of the electric slide block 41. Positioning platforms 5 are fixedly installed on both sides of the top surface of the movable seat 42. There are two positioning platforms 5. Positioning strips 11 are fixedly installed on both sides of the top surface of the worktable 1. There are two positioning strips 11. The two positioning platforms 5 cooperate with the two positioning strips 11 respectively. A first auxiliary plate 51 is fixedly installed on one side of the top surface of the positioning platform 5. A second auxiliary plate 52 is fixedly installed on the side of the top surface of the positioning platform 5 perpendicular to the first auxiliary plate 51.

A motor 62 is fixedly installed in one side of the drive frame 61. A lead screw 63 is fixedly installed at the output end of the motor 62. An adjusting sleeve 64 is threaded on the surface of the lead screw 63. A positioning plate 7 is fixedly installed on the top surface of the adjusting sleeve 64. The positioning plate 7 cooperates with the first auxiliary plate 51 and the second auxiliary plate 52.

[0021] The workpieces to be welded are sequentially fed into the working chamber 2 through two positioning platforms 5 in a cyclical manner. Initially, the two positioning platforms 5 are located on the left side above the workbench 1 and inside the working chamber 2, respectively. The workpiece to be welded is placed on the left positioning platform 5 with the welding surface facing upwards, and its two sides are respectively in contact with the first auxiliary plate 51 and the second auxiliary plate 52. After placement, the switch of the motor 62 in the corresponding drive device 6 of the left positioning platform 5 is turned on. The motor 62 controls the lead screw 63 to rotate. When the lead screw 63 rotates, it controls the adjusting sleeve 64 to move the positioning plate 7 on the positioning platform 5. When one side of the positioning plate 7 is in contact with the surface of the placed workpiece, the workpiece is positioned on the left positioning platform 5. The switch of the electric slide rail 4 is turned on. The electric slide rail 4 controls the electric slide block 41 and the moving seat 42 to move the two positioning platforms 5 to the right. When one side of the positioning platform 5 located in the working chamber 2 is in contact with the side of the positioning strip 11 on the right side of the top surface of the workbench 1, the electric slide rail 62 is turned on. When slide rail 4 stops working, the workpiece positioned on the left positioning table 5 moves into the working chamber 2 and is then welded by laser welding device 3. While the workpiece on the left positioning table 5 in the working chamber 2 is being welded, the next workpiece to be welded is placed on the right positioning table 5. The workpiece is positioned on the right positioning table 5 in the same way as the workpiece on the left positioning table 5. After the workpiece on the left positioning table 5 in the working chamber 2 is welded, the electric slide rail 4 starts working. The electric slide rail 4 controls the electric slide base 41 and the moving base 42 to move the two positioning tables 5 to the left. When one side of the left positioning table 5 is in contact with one side of the left positioning strip 11 on the top surface of the worktable 1, the electric slide rail 4 stops working, and the workpiece positioned on the right positioning table 5 moves into the working chamber 2 and is then welded by laser welding device 3. While welding, the welded workpiece on the left positioning table 5 is removed, and the positioning of the spare workpiece is continued. This process is repeated until the welding of the workpiece is completed.

[0022] A working chamber 2 is fixedly installed on the top surface of the workbench 1. A laser welding device 3 is installed on the top surface of the working chamber 2. Through slots 21 are provided on both sides of the working chamber 2. A protective plate 43 is fixedly installed in the middle of the top surface of the movable base 42. The through slots 21 and the protective plate 43 cooperate with each other. The laser welding device 3 installed on the top surface of the working chamber 2 completes the welding work on the workpiece moved into the working chamber 2. This laser welding device 3 is existing technology. The control unit controls the drive assembly to drive the laser welding head of the laser welding device 3 to move forward, backward, left, right, and up and down, moving the laser welding head to the designated welding position for welding workpieces. The working chamber 2 increases the protection of the laser welding device 3 during welding, preventing injury to workers. The through slot 21 facilitates the movement of the two positioning platforms 5 into and out of the working chamber 2 after the positioned workpiece has been placed. When the workpiece to be welded on the left positioning platform 5 stops in the working chamber 2, the protective plate 43, with the cooperation of the positioning strip 11, enters the through slot 21 on the right side of the working chamber 2 to block the right through slot 21, preventing the laser welding device 3 from injuring the workers when they are loading or unloading the workpiece on the right positioning platform 5. Similarly, when the workpiece to be welded on the right positioning platform 5 stops in the working chamber 2, the protective plate 43, with the cooperation of the positioning strip 11, enters the through slot 21 on the left side of the working chamber 2 to block the left through slot 21, preventing the laser welding device 3 from injuring the workers when they are loading or unloading the workpiece on the left positioning platform 5.

[0023] Two guide rails 12 are symmetrically installed on the top surface of the workbench 1 between two positioning bars 11. Sliding sleeves 53 are fixedly installed on both sides of the bottom surface of the two positioning platforms 5. The two sliding sleeves 53 on the same side of the bottom surface of the two positioning platforms 5 are slidably fitted onto the surface of a guide rail 12. The guide rail 12 and the sliding sleeves 53 cooperate with each other. Each positioning platform 5 moves by the cooperation of two guide rails 12 and two sliding sleeves 53. The sliding sleeves 53 slide on the corresponding guide rail 12 surface as the positioning platform 5 moves. With the cooperation of the sliding sleeves 53 and the guide rails 12, the stability of the positioning platform 5 when it moves is increased.

[0024] The top surface of the positioning platform 5 is symmetrically provided with a groove 54, and a guide rod 55 is fixedly installed in the groove 54. Guide sleeves 71 are fixedly installed on both sides of the bottom surface of the positioning plate 7. The guide sleeves 71 are slidably sleeved on the surface of the guide rod 55. When the positioning plate 7 moves on the positioning platform 5 by the driving device 6, the guide sleeves 71 installed on both sides of the bottom surface of the positioning plate 7 slide in the groove 54 on the corresponding surface of the guide rod 55. With the cooperation of the guide sleeves 71 and the guide rods 55, the stability of the positioning plate 7 when moving is increased, and the guiding work of the positioning plate 7 is completed at the same time.

[0025] An observation window 22 is fixedly installed on one side of the working chamber 2. The observation window 22 works in conjunction with the working chamber 2 to facilitate the observation of the working status of the laser welding device 3 inside the working chamber 2.

[0026] Two rotating parts 631 are fitted on both ends of the surface of the lead screw 63. The two rotating parts 631 are fixedly installed on both sides of the drive frame 61. The rotating parts 631 cooperate with the lead screw 63 to complete the installation and positioning of the lead screw 63 in the drive frame 61, and at the same time assist the lead screw 63 in rotating. A support base 8 is fixedly installed on the bottom surface of the worktable 1. The support base 8 cooperates with the worktable 1. The device is installed in the designated area for welding workpieces through the cooperation of the support base 8 and the worktable 1.

[0027] Working Principle: The workpiece to be welded is sequentially fed into the working chamber 2 via two cyclic positioning platforms 5. Initially, the two positioning platforms 5 are located on the left side above the worktable 1 and inside the working chamber 2, respectively. The workpiece to be welded is placed on the left positioning platform 5 with the welding surface facing upwards, and its two sides are respectively in contact with the first auxiliary plate 51 and the second auxiliary plate 52. After placement, the switch of the motor 62 in the corresponding drive device 6 of the left positioning platform 5 is turned on. The motor 62 controls the lead screw 63 to rotate. When the lead screw 63 rotates, it controls the adjusting sleeve 64 to move the positioning plate 7 on the positioning platform 5. When one side of the positioning plate 7 is in contact with the surface of the placed workpiece, the workpiece is positioned on the left positioning platform 5. The switch of the electric slide rail 4 is turned on. The electric slide rail 4 controls the electric slide block 41 and the moving seat 42 to move the two positioning platforms 5 to the right. When one side of the positioning platform 5 in the working chamber 2 is in contact with the side of the positioning strip 11 on the right side of the top surface of the worktable 1, the workpiece is positioned. When the electric slide rail 4 stops working, the workpiece positioned on the left positioning table 5 moves into the working chamber 2 and is then welded by the laser welding device 3. While the workpiece on the left positioning table 5 in the working chamber 2 is being welded, the next workpiece to be welded is placed on the right positioning table 5. The workpiece is positioned on the right positioning table 5 in the same way as the workpiece on the left positioning table 5. When the workpiece on the left positioning table 5 in the working chamber 2 is welded, the electric slide rail 4 starts working. The electric slide rail 4 controls the electric slide block 41 and the moving block 42 to move the two positioning tables 5 to the left. When one side of the left positioning table 5 is in contact with one side of the left positioning strip 11 on the top surface of the worktable 1, the electric slide rail 4 stops working, and the workpiece positioned on the right positioning table 5 moves into the working chamber 2 and is then welded by the laser welding device 3. While welding, the welded workpiece on the left positioning table 5 is removed, and the positioning of the spare workpiece is continued. This process is repeated until the welding of the workpiece is completed.

[0028] The working chamber 2 enhances the protective function of the laser welding device 3 during welding, preventing injury to workers. The through-slot 21 facilitates the movement of positioned workpieces from and from the two positioning platforms 5. When a workpiece to be welded on the left positioning platform 5 enters and stops in the working chamber 2, the protective plate 43, in conjunction with the positioning strip 11, enters the through-slot 21 on the right side of the working chamber 2, sealing the right through-slot 21 to prevent injury from the laser welding device 3 when workers are loading or unloading workpieces from the positioning platform 5 on the right. Similarly, when a workpiece to be welded on the right positioning platform 5 enters and stops in the working chamber 2, the protective plate 43, in conjunction with the positioning strip 11, enters the through-slot 21 on the left side of the working chamber 2, sealing the left through-slot 21 to prevent injury from the laser welding device 3 when workers are loading or unloading workpieces from the positioning platform 5 on the left.
