Description

Technical Field

[0001] The utility model relates to the technical field of LED bulb shell production, in particular to a laser welding machine for LED bulb shell production. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the workpiece surface, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it is widely used in practice. This technology is used in the production of LED bulb shells.

[0003] In the process of producing LED bulb shells, the operator is required to fix the workpiece on the workbench of the laser welder and operate the laser welder to complete the welding operation. Since the common laser welder workbench cannot be rotated, and a single workpiece generally has multiple points that need to be welded, in order to facilitate the rotation of the workpiece during welding, the operator usually places the workpiece directly on the workbench surface without fixing it. The unfixed workpiece may slip during operation, affecting the product accuracy and posing certain safety hazards. In order to facilitate the rotation of the workpiece and prevent the unfixed workpiece from sliding on the workbench, improve work efficiency and ensure product quality, we propose a laser welder for the production of LED bulb shells.

[0028] When in use, place the workpiece on the rotating assembly. The operator can easily rotate the workpiece through the rotating assembly. At the same time, the moving assembly can drive the workpiece to move forward, backward, left and right. The operator can then conveniently weld different points on the workpiece. The height of the equipment can also be adjusted through the lifting assembly to facilitate use by operators of different heights.

[0029] The rotating assembly also includes several groups of support rods 15, which are slidably connected to the top of the rotating disk 14, and a slider is fixedly connected to the bottom of the support rod 15.

Rotating the second turntable 30 drives the second screw 32 to rotate, causing the second movable block 29 to move back and forth, driving the top plate 18 to slide back and forth on the second connecting block 31, thereby driving the workpiece to move back and forth, left and right, to facilitate welding operations.

[0034] The lifting assembly includes a motor 11, which is fixedly mounted on the rear side of the bottom box 2. The output end of the motor 11 is rotated and passed into the bottom box 2. The output end of the motor 11 is fixedly connected to a driving rod 26. A fixed sleeve outside the driving rod 26 is provided with several groups of driving wheels 25. Several groups of rotating rods 23 are rotatably mounted on the inner wall of the bottom box 2. A fixed sleeve outside the rotating rod 23 is provided with a driven wheel 24.

[0035] The starting motor 11 drives the driving rod 26 to rotate, and the rotating rod 23 is driven to rotate through the driven wheel 24 and the driving wheel 25. The driving bevel gear 27 rotates, causing the driven bevel gear 22 to rotate, driving the threaded sleeve 20 to rotate, and under the action of the lifting screw 21, the base plate 1 moves up and down, thereby adjusting the overall height of the equipment to facilitate use by operators of different heights.

[0036] A plurality of telescopic rods 28 are fixedly connected to the bottom of the base plate 1, and the bottom of the telescopic rods 28 is fixedly connected to the bottom box 2, which can make the equipment more stable when it is lifted or lowered.

[0037] A positioning screw 16 is threadedly connected to the rotating disk 14, and a positioning turntable 17 is fixedly connected to the top of the positioning screw 16. Rotating the positioning turntable 17 drives the positioning screw 16 to rotate, so that the positioning screw 16 is pressed against the top plate 18. Then the rotating disk 14 cannot rotate, that is, the workpiece cannot rotate, thereby ensuring the stability of the workpiece during welding.

[0038] A mounting rod 12 is fixedly connected to the top of the mounting box 10, and a display screen 7 is mounted on the outer surface of the mounting rod 12 to facilitate operators to adjust and confirm various parameters of the equipment.

[0041] Working principle: When in use, place the workpiece on the top of the placement plate 13. Under the action of gravity, the spring 40 is compressed, the placement plate 13 drops, and the support rod 15 moves closer to the placement plate 13 under the action of the U-shaped block 19. At the same time, the U-shaped block 19 rotates around the support rod 15 until the U-shaped block 19 abuts against the workpiece, so that the workpiece is fixed. The workpiece can be driven to rotate by rotating the rotating disk 14. A positioning screw 16 is threadedly connected to the rotating disk 14. A positioning turntable 17 is fixedly connected to the top of the positioning screw 16. Rotating the positioning turntable 17 drives the positioning screw 16 to rotate, so that the positioning screw 16 abuts against the top plate 18. The rotating disk 14 cannot rotate, that is, the workpiece cannot rotate, thereby ensuring the stability of the workpiece during welding. Rotating the first turntable 38 drives the second turntable 38 to rotate. A screw 35 rotates to move the first moving block 36 left and right, driving the connecting plate 33 to slide left and right on the first connecting block 34. The second turntable 30 is rotated to drive the second screw 32 to rotate, so that the second moving block 29 moves back and forth, driving the top plate 18 to slide back and forth on the second connecting block 31, thereby driving the workpiece to move back and forth and left and right, which is convenient for welding operation. The starting motor 11 drives the driving rod 26 to rotate, and drives the rotating rod 23 to rotate through the driven wheel 24 and the driving wheel 25. The driving bevel gear 27 rotates, causing the driven bevel gear 22 to rotate, driving the threaded sleeve 20 to rotate, and under the action of the lifting screw 21, the bottom plate 1 moves up and down, thereby adjusting the overall height of the equipment to facilitate use by operators of different heights.
