DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0022] This embodiment provides a technical solution: a high-voltage cabinet door panel laser welding workstation of the present application includes a welding robot 13, a water cooler 3, a robot control cabinet 4, a laser cabinet 5, a welding room 2, and a welding station assembly. The water cooler 3 is connected to the laser cabinet 5, and the laser cabinet 5 and the robot control cabinet 4 are connected to the welding robot 13. The welding robot 13 is equipped with an automatic telescopic wire feeding device, a weld tracking device and a laser welding head. The workstation is also equipped with an electric cabinet 7, a part of which is electrically connected to a regulated power supply to power the welding robot 13 and the robot control cabinet 4. The welding robot 13, the water cooler 3, the robot control cabinet 4, and the laser cabinet 5 are installed in the welding room 2. The welding station assembly includes a positioner 8, a fence and a light curtain protection device 1. The positioner 8 is a horizontal rotation type Three-axis positioner, the horizontal rotary three-axis positioner 8 includes a frame that can rotate around a vertical axis in the horizontal plane, the frame is H-shaped, and the frame is equipped with a tooling fixture 9 at both ends of the H-shape that can be flipped around a horizontal axis formed by the line connecting the ends of the H-shape. The frame is equipped with a partition screen 12 on the middle crossbeam of the H-shape, and a door and a screen hole consistent with the shape of the partition screen 12 are opened on the wall of the welding room 2. The partition screen 12 of the positioner 8 is fitted with the wall of the welding room 2 in the horizontal stop position of the frame to form a closed space in the welding room 2. By adding a screen in the middle of the positioner 8, the isolation and blocking inside and outside the welding room 2 can be maximized to ensure that the operating personnel do not directly contact the first welding site, and prevent the overflow of "waste smoke, exhaust gas, high temperature and arc light" inside the welding room 2, thereby ensuring the safety and health of the operating personnel. A remote operation control unit 11 is also provided outside the welding room 2. The remote operation control unit 11, together with the positioner 8, the welding robot 13, the robot control cabinet 4 and the like, constitutes an electrical control system to control the clamping and welding operations of the entire welding station.

[0023] The partition screen 12 divides the frame inside the welding room 2 into an external clamping area and an internal welding area. The welding robot 13 is installed at the welding position next to the welding area. The double-station free-rotating positioner 8 can effectively separate the workpiece clamping area and the welding area, realizing both workpiece clamping and welding operations, effectively improving welding efficiency.

[0024] The light curtain protection device 1 is installed on both sides of the clamping area and extends outward from the wall of the welding room 2 to the outside of the tooling fixture 9 area to form a protection area. During the welding operation, once someone mistakenly enters the protection area, the existing welding operation will be stopped, effectively ensuring the safety of the welding operation.

[0025] In this embodiment, two sets of welding station assemblies are configured and placed adjacent to each other along the side walls of the welding room 2. The two side walls of the welding room 2 are perpendicular to each other, so that different types of door panels, such as concave and convex door panels and flat door panels, can be welded at different positions. When two sets of welding robots 13 are configured, they are specifically used for two sets of different types of door panel welding tooling operations respectively. Two different types of door panels can be processed in the same time period, and the welding capacity can be greatly improved.

[0026] When the funds for equipment procurement are relatively limited, an underground slide rail 10 can be configured. As shown in this embodiment, the underground slide rail 10 is installed underground in the welding room 2 along the welding position. The welding robot 13 is installed on the underground slide rail 10 and slides between different welding positions to fix the welding position. The welding operation of the welding robot 13 can be flexibly adjusted according to the production situation of the day. Only one type of door panel welding operation can be performed in the same time period.

[0027] In this embodiment, a monitoring device 21 is also installed in the upper portion of the interior of the welding room 2. The monitoring device 21 can be a different type of camera. The monitoring device 21 is directed toward the welding area of ​​the welding robot 13. In this embodiment, the monitoring device 21 is a bolt-action type, hoisted in the top corner of an open area within the welding room 2. Alternatively, a panoramic type can be installed in the center of the top. In this embodiment, a large-diameter transparent observation window 19 is provided on the exterior wall of the welding room 2, and a large-screen display 20 is provided, which is connected to the internal monitoring device 21. The display 20 displays the real-time content captured by the monitoring device 21, making it convenient for workers and visitors to observe the welding process in real time. An alarm device 22 is also installed in a conspicuous location outside the welding room 2 and is effectively connected to the internal monitoring device 21 of the welding room 2. If any abnormality occurs during the welding process that affects welding quality or even production safety, an alarm is immediately triggered, allowing workers to follow up and make adjustments in real time. The alarm device 22 can use different types of sound and light alarm lights.

[0028] Dust removal equipment 6 is also installed outside the welding room 2. This dust removal equipment 6 is connected to the welding area of ​​the welding robot 13 within the welding room 2 via a dust removal pipe installed on the wall of the welding room 2. In this embodiment, a top-suction dust removal pipe is used. A side-suction pipe can also be used to cover the welding area where appropriate to meet the dust removal requirements of the laser welding area and provide rapid dust removal. This dust removal equipment 6, together with the electrical control system, constitutes a fume and dust removal system.

[0029] In this embodiment, each of the welding station components also includes a transfer cantilever crane 16, which is installed on the outside of the welding room 2, next to the clamping area of ​​the positioner 8 within the protection range of the fence and light curtain protection device 1. It is flexible and reliable, and has a large-angle rotation function. It is used for door panel lifting, loading and unloading and other operation processes. In this embodiment, semi-finished product temporary storage 14 and finished product temporary storage 15 for transfer cantilever crane 16 to transfer and suspend are set on both sides of each fence and light curtain protection device 1, which ensures operation safety and reduces the labor intensity of employees.

[0030] In this embodiment, the door of the welding room 2 adopts a push-pull sliding door 17. The staff can only open the welding room door axially in a non-hinged manner, which is convenient for personnel to enter and exit, does not take up additional space, and ensures that personnel inside and outside the welding room can be effectively evacuated in dangerous moments.
