Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically to a laser welding device based on an integrated laser control cabinet system. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It is an important application of laser materials processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction type, meaning that laser radiation heats the surface of the workpiece, and the surface heat diffuses inward through heat conduction. By controlling parameters such as 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 has been successfully applied to the precision welding of micro and small parts.

[0003] In modern industrial production, laser welding technology is widely used in various fields due to its high precision and high efficiency. However, existing laser welding equipment usually suffers from poor heat dissipation, which not only affects the stable operation of the equipment but may also shorten its service life. Currently, most laser welding equipment is a discrete system with each component deployed independently, each part performing a single function. For example, the equipment control system controls the equipment's actions, the laser system controls the generation of laser light, the industrial control computer system controls the galvanometer, and the chiller system cools the equipment. Each subsystem occupies valuable factory space, has complex wiring, and makes information exchange between them difficult.

[0004] Therefore, based on the above problems, we have invented a laser welding device based on an integrated laser control cabinet system. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser welding device based on an integrated laser control cabinet system, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser welding equipment based on an integrated laser control cabinet system, comprising a cabinet body, with a front cabinet door and a rear cabinet door hinged to the front and rear ends of the cabinet body respectively; a back panel is vertically installed inside the cabinet body; two partitions are slidably installed at the front end of the back panel; a space adjustment mechanism for adjusting the two partitions is provided inside the cabinet body; a laser generator is installed inside the two partitions; a water chiller is installed in the space below the partitions in the cabinet body; a mounting frame is installed in the space above the partitions in the cabinet body; a base is installed at the rear end of the back panel; a welding table is installed on the base; a laser head is provided above the welding table; a lifting mechanism for raising and lowering the laser head is provided inside the cabinet body; and a cooling ring is wrapped around the laser head.

[0007] Furthermore, the space adjustment mechanism includes two lifting slots respectively disposed on the opposite sidewalls of the two partitions. A heat exchange plate is slidably installed on the lifting slots. Two bidirectional screws are rotatably installed in the lifting slots. Two threaded blocks are threaded onto the external threads of the bidirectional screws. The threaded blocks are slidably installed with the lifting slots. A deflection plate is rotatably installed on the threaded blocks. The end of the deflection plate away from the threaded blocks is rotatably installed with the heat exchange plate. A transmission slot is provided on the inner wall of the cabinet. A buffer plate is fixedly installed in the transmission slot. One end of each of the four bidirectional screws rotatably passes through the partition and extends into the transmission slot. The four bidirectional screws are connected by a synchronous transmission mechanism. A drive motor is installed in the transmission slot. The drive shaft of the drive motor is coaxially installed with one of the bidirectional screws.

[0008] Furthermore, the synchronous transmission mechanism includes four synchronous pulleys, which are coaxially mounted with four bidirectional screws. The four synchronous pulleys are connected to each other via a synchronous belt drive. The buffer plate is provided with a buffer groove, and a limit rod is fixedly connected inside the buffer groove. A buffer slider is slidably mounted outside the limit rod. The buffer slider is slidably mounted with the buffer groove. A buffer spring is sleeved on the limit rod. The two ends of the buffer spring are fixedly connected to the buffer slider and the inner wall of the buffer groove, respectively. Transition pulleys are mounted on both buffer sliders, and the synchronous belt passes through the two transition pulleys.

[0009] Furthermore, the back plate is provided with an adjustment groove, in which a bidirectional adjustment screw is rotatably installed. Two lifting blocks are threaded onto the external thread of the bidirectional adjustment screw, and the two lifting blocks are respectively fixedly connected to two partitions. An adjustment motor is installed in the adjustment groove, and the drive shaft of the adjustment motor is coaxially installed with the bidirectional adjustment screw.

[0010] Furthermore, the lifting mechanism includes a mounting plate for mounting the laser head. Sleeves are fixedly mounted at the four lower corners of the mounting plate. Sleeves are fitted over the sleeves, and the lower ends of the sleeves are fixedly mounted to the base. The four sleeves are fixedly connected by connecting rods. A lifting screw is threadedly connected to the lower end of each sleeve. A transmission cavity is provided inside the base. The lower ends of the four lifting screws rotatably penetrate the base and extend into the transmission cavity. The four lifting screws are connected by a lifting transmission mechanism. A lifting motor is installed inside the transmission cavity, and the drive shaft of the lifting motor is coaxially mounted with one of the lifting screws.

[0011] Furthermore, the lifting transmission mechanism includes four lifting pulleys, which are coaxially mounted with four lifting screws, and are connected to each other by a synchronous belt drive.

[0012] Furthermore, the water chiller is connected to the heat exchange plate and the cooling ring.

[0013] Furthermore, each of the two threaded blocks located outside the same bidirectional screw is provided with a threaded hole that matches the bidirectional screw, and the threads in the two threaded holes have opposite directions.

[0014] Furthermore, both lifting blocks are provided with threaded holes that match the bidirectional adjusting screw, and the threads in the two threaded holes rotate in opposite directions.

[0015] Compared with the prior art, the present invention provides a laser welding device based on an integrated laser control cabinet system, which has the following advantages: 1. By setting up a space adjustment mechanism, including heat exchange plates and bidirectional screws, effective contact between the upper and lower sides of the laser generator is achieved, thereby significantly improving heat dissipation efficiency. This design not only enhances the cooling performance of the equipment, but also helps to extend the service life of key components.

[0016] 2. By rationally arranging functional modules such as water chillers, mounting racks, and laser generators within the same cabinet, space is saved while ensuring coordinated operation between various parts. This significantly reduces the equipment's footprint and improves energy efficiency. Furthermore, due to its high integration, operators only need one interactive window to complete all operations and monitoring, greatly reducing training time. The optimized and reduced wiring after integration also greatly improves the stability of the equipment, reducing downtime and increasing production capacity.

[0017] This application improves the heat dissipation efficiency of the laser generator, integrates multiple components into a single cabinet to save space, and ensures coordinated operation between the components, thereby improving the stability of the equipment. Attached Figure Description

[0023] Through the above-mentioned technical features, the laser generator 7, chiller 6, etc. are integrated into the same cabinet 1, which greatly reduces the floor space occupied by the equipment, reduces exposed wiring and pipes, and facilitates subsequent maintenance.

[0024] To improve the heat dissipation of the laser generator 7, a space adjustment mechanism 4 is provided. The space adjustment mechanism 4 includes two lifting grooves 12 respectively located on the opposite side walls of the two partitions 3. A heat exchange plate 13 is slidably mounted on the lifting grooves 12. It should be noted that the water chiller 6 is connected to both the heat exchange plate 13 and the cooling ring 9. Two bidirectional screws 14 are rotatably mounted within the lifting grooves 12. Two threaded blocks 15 are threaded onto the external threads of the bidirectional screws 14. It should be noted that both threaded blocks 15 located outside the same bidirectional screw 14 have threaded holes matching the bidirectional screw 14, with the threads in the two threaded holes rotating in opposite directions. The threaded blocks 15 are slidably mounted with the lifting grooves 12.

The drive shaft of the drive motor 17 is coaxially mounted with one of the bidirectional screws 14.

[0025] Through the above technical features: on the one hand, by adjusting the drive shaft of the motor 28 to drive the bidirectional adjusting screw 26 to rotate, the bidirectional adjusting screw 26 drives the two lifting blocks 27 to move relative to each other, and the lifting blocks 27 drive the two partitions 3 to rise and fall relative to each other, which facilitates the installation of equipment in the cabinet 1. On the other hand, by driving the drive shaft of the drive motor 17 to drive the four bidirectional screws 14 to rotate, the bidirectional screws 14 drive the two threaded blocks 15 to move relative to each other, and the threaded blocks 15 drive the heat exchange plates 13 to rise and fall through the deflection plate 38, which can drive the two heat exchange plates 13 to rise and fall relative to each other, so that the two heat exchange plates 13 can be in contact with the upper and lower sides of the laser generator 7, thereby increasing the heat dissipation area of ​​the laser generator 7 and improving the heat dissipation efficiency of the laser generator 7.

[0026] To adjust the height of the laser head 41, a lifting mechanism 10 is provided. The lifting mechanism 10 includes a mounting plate 36 that is installed on the laser head 41. A sleeve rod 35 is fixedly installed at each of the four corners of the lower end of the mounting plate 36. A sleeve 34 is sleeved on the sleeve rod 35. The lower end of the sleeve 34 is fixedly installed on the base 11. The four sleeves 34 are fixedly connected to each other by a connecting rod.

The four lifting screws 31 are connected to each other by a lifting transmission mechanism 32. It should be noted that the lifting transmission mechanism 32 includes four lifting pulleys 33. The four lifting pulleys 33 are coaxially installed with the four lifting screws 31 respectively. The four lifting pulleys 33 are connected to each other by a synchronous belt. A lifting motor 30 is installed inside the transmission cavity 29. The drive shaft of the lifting motor 30 is coaxially installed with one of the lifting screws 31.

[0027] Through the above technical features: the drive shaft of the lifting motor 30 drives the four lifting screws 31 to rotate, the four lifting screws 31 drive the four sleeve rods 35 to rise and fall, the four sleeve rods 35 drive the mounting plate 36 to rise and fall, and the mounting plate 36 drives the laser head 41 to rise and fall, so the height of the laser head 41 can be adjusted, which is relatively convenient.

[0028] Working principle: 1) Adjusting the height of the laser head 41: The drive shaft of the lifting motor 30 drives the four lifting screws 31 to rotate, the four lifting screws 31 drive the four sleeve rods 35 to rise and fall, the four sleeve rods 35 drive the mounting plate 36 to rise and fall, and the mounting plate 36 drives the laser head 41 to rise and fall, so the height of the laser head 41 can be adjusted, which is relatively convenient. 2) Installation and heat dissipation of laser generator 7: The drive shaft of the adjusting motor 28 drives the bidirectional adjusting screw 26 to rotate. The bidirectional adjusting screw 26 drives the two lifting blocks 27 to move relative to each other. The lifting blocks 27 drive the two partitions 3 to rise and fall relative to each other, which facilitates the installation of equipment in the cabinet 1. On the other hand, the drive shaft of the same motor 17 drives the four bidirectional screws 14 to rotate. The bidirectional screws 14 drive the two threaded blocks 15 to move relative to each other. The threaded blocks 15 drive the heat exchange plates 13 to rise and fall through the deflection plate 38, which drives the two heat exchange plates 13 to rise and fall relative to each other. This allows the two heat exchange plates 13 to come into contact with the upper and lower sides of the laser generator 7, thereby increasing the heat dissipation area of ​​the laser generator 7 and improving the heat dissipation efficiency of the laser generator 7.
