Description

Technical Field

[0001] This utility model relates to the field of laser welding machine technology, and in particular to a multi-station laser welding machine. Background Technology

[0002] A laser welding machine is a device that uses a laser beam as a heat source to weld materials. The working principle of a laser welding machine is to convert the laser beam into a high-energy heat source through a converter, which then irradiates the surface of the workpiece, causing the surface to melt and weld together. Laser welding machines are frequently used in the processing of food molds such as baking molds, cake molds, and toast box molds.

[0003] Chinese patent application publication number CN217965288U discloses a multi-station laser welding machine, including a welding machine body with a vertical frame plate on the machine body. A worktable is mounted on the frame plate, and several clamping mechanisms for holding workpieces are sequentially arranged on the top surface of the worktable. Several welding heads are located above the clamping mechanisms on the frame plate. While this patent allows for simultaneous welding of multiple workpieces, the workpieces are clamped separately, and even when clamping identical workpieces, the process is cumbersome and time-consuming.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-4A multi-station laser welding machine includes a worktable 1, a mounting frame 2 fixedly mounted on the side of the worktable 1, a drive motor 3 fixedly mounted on the right side of the mounting frame 2, the output end of the drive motor 3 extending through the mounting frame 2 to the left side of the mounting frame 2 and fixedly mounted with a rotating rod 4, a transmission assembly provided on the surface of the rotating rod 4, and a movable plate 9 provided on the top of the rotating rod 4 through the transmission assembly, a slot 11 provided on the top of the movable plate 9, a plug 12 inserted into the slot 11, the plug 12 having a T-shaped structure and being made of metal, the slot 11 and the plug 12 being adapted to each other so that the plug 12 can only be inserted from above the slot 11. Insertion or withdrawal: A clamping block 13 is fixedly installed on the opposing surface of the insertion block 12. The transmission assembly includes a first pulley 5 disposed on the surface of the rotating rod 4. A synchronous belt 6 is meshed on the surface of the first pulley 5. A second pulley 7 is meshed on the inner wall of the synchronous belt 6. A screw 8 is fixedly installed inside the second pulley 7. The screw 8 is a bidirectional threaded rod made of metal. There are multiple screws 8 to ensure higher structural strength and durability. The screw 8 is threadedly connected to the moving plate 9. A fixed plate 27 is rotatably connected to the surface of the screw 8. The fixed plate 27 is fixedly connected to the worktable 1. The fixed plate 27 is internally fixed. A guide rod 10 is fixedly installed, and the guide rod 10 is slidably connected to the moving plate 9. When the rotating rod 4 rotates, the first pulley 5 rotates, which causes the synchronous belt 6 to drive the second pulley 7 to rotate, causing the screw 8 to rotate. This causes the moving plates 9 to move closer together along the guide rod 10, facilitating transmission when the rotating rod 4 rotates. This also allows the clamping block 13 to clamp and fix multiple identical food molds 19 simultaneously. A rectangular tube 14 is fixedly installed on the top of the insertion block 12, and a limit component is provided on the top of the insertion block 12. The food molds 19 are attached to the top of the worktable 1, and a welding component is provided on the top of the worktable 1. This multi-station laser welding machine can weld multiple identical food molds 19 together. The same food molds 19 are placed on the workbench 1. The drive motor 3 causes the rotating rod 4 to rotate, which in turn drives the transmission component to move the moving plates 9 closer together. This causes the insert block 12 to drive the clamping block 13 closer together, so that the clamping block 13 can clamp and fix multiple identical food molds 19 at the same time. Then, the food molds 19 are processed by the welding component. This achieves the goal of fixing multiple identical food molds 19 at the same time, which simplifies the clamping process of the identical food molds 19. Moreover, multiple food molds 19 can be fixed with one motor, thereby reducing motor waste.

[0023] according to Figure 3As shown, the limiting component includes a fixed block 15 disposed on the top of the movable plate 9. A spring 16 is fixedly mounted on the surface of the fixed block 15, a pull plate 17 is fixedly mounted on the surface of the spring 16, and an insertion rod 18 is fixedly mounted on the surface of the pull plate 17. The insertion rod 18 is slidably connected to the fixed block 15. Pulling the pull plate 17 to both sides causes the insertion rod 18 to move away from each other. At the same time, the spring 16 is stretched, causing the insertion rod 18 to separate from the rectangular tube 14, which facilitates the release of the limiting on the rectangular tube 14, thereby facilitating the release of the limiting on the insertion block 12. When the pull plate 17 is released, the force generated by the stretching of the spring 16 can cause the pull plate 17 to drive the insertion rod 18 to move closer to each other, so that the insertion rod 18 is inserted into the rectangular tube 14, which facilitates the limiting on the rectangular tube 14, thereby facilitating the limiting on the insertion block 12.

[0024] according to Figure 4 As shown, the welding assembly includes multiple support frames 20 mounted on the top of the workbench 1, arranged in an array. Each support frame 20 has an L-shaped structure. An electric push rod 21 is fixedly mounted on the top of each support frame 20. A first linear motor 22 is fixedly mounted on the output end of the electric push rod 21. A first movable seat 23 is mounted on the first linear motor 22. A second linear motor 24 is fixedly mounted on the bottom of the first movable seat 23. A second movable seat 25 is mounted on the second linear motor 24. A welding head 26 is fixedly mounted on the bottom of the second movable seat 25. The height of the welding head 26 can be controlled by the electric push rod 21, facilitating welding of the food mold 19. The first linear motor 22 controls the first movable seat 23 to move left and right, facilitating adjustment of the left and right position of the welding head 26. The second linear motor 24 controls the second movable seat 25 to move forward and backward, facilitating adjustment of the forward and backward position of the welding head 26.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0026] In use: Place multiple identical food molds 19 on the workbench 1, start the drive motor 3 to rotate the rotating rod 4, which in turn rotates the first pulley 5, causing the synchronous belt 6 to drive the second pulley 7 to rotate, which in turn rotates the screw 8, causing the moving plates 9 to move closer together along the guide rod 10, causing the insert block 12 to drive the clamping block 13 to move closer together, so that the clamping block 13 simultaneously clamps and fixes multiple identical food molds 19. Then, start the first linear motor 22 to move the first moving seat 23 left and right to the appropriate position, start the second linear motor 24 to move the second moving seat 25 back and forth to the appropriate position, and start the electric push rod 21 to drive the first linear motor 22 to drive the first moving seat 25 to the appropriate position. 3. Move downwards, causing the second linear motor 24 to drive the second moving seat 25 downwards, so that the welding head 26 moves downwards to a suitable height to weld the food mold 19. The clamping block 13 is replaced according to the different needs of the food mold 19. Pull the pull plate 17 to both sides, so that the insertion rods 18 move away from each other. At the same time, the spring 16 is stretched, so that the insertion rods 18 are separated from the rectangular tube 14. Then, the insertion block 12 is taken out from the slot 11, completing the disassembly of the clamping block 13. Then, the insertion block 12 on the new clamping block 13 is inserted into the slot 11. The pull plate 17 is released. The spring 16 can make the pull plate 17 drive the insertion rods 18 to move closer to each other, so that the insertion rods 18 are inserted into the rectangular tube 14.
