Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, and in particular to a light-shielding device for a welding system. Background Technology

[0002] During arc welding operations at a robotic arc welding workstation, intense arc light is generated. This light can severely damage the operator's eyes and may also interfere with the vision of others in the vicinity. Simultaneously, the welding fumes produced during the welding process cannot be ignored, and fume extraction systems are typically used to remove them. To prevent welding fumes from escaping, ensure effective fume extraction, and reduce the concentration of fumes in the working environment, light-shielding curtains are usually installed at the arc welding station to block both arc light and fumes.

[0003] However, existing arc welding station shading curtains have many problems: First, most traditional shading curtains use roller shutters for opening and closing, which poses safety hazards; second, some electric shading curtains cannot differentiate the opening and closing speeds, failing to meet the efficiency requirements of actual use. For example, opening too slowly will delay the work process, while closing too quickly can easily cause a large impact, affecting the service life of the equipment; traditional safety doors are expensive, difficult to install, and require customization according to different arc welding stations; they also have a high failure rate and are difficult to maintain.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] 1. High degree of automation: Through the coordinated work of rodless cylinders and solenoid valves, the automatic single-opening control of the light-shielding curtain is realized, and it is closely linked with the operation of the arc welding robot. No manual operation is required, which significantly improves work efficiency and makes the arc welding process smoother and more automated.

[0016] 2. Reasonable speed control: By adjusting the air intake of the solenoid valve, the blackout curtain can operate at high speed when open to quickly block arc light and reduce the harm of arc light to personnel; and operate at low speed when closed to avoid generating large impacts, extend the service life of the equipment, and improve the safety and stability of use.

[0017] 3. Strong anti-interference ability: The counterweight at the lower end of the light-blocking curtain effectively prevents the light-blocking curtain from swaying when using equipment such as fans in summer, preventing it from interfering with the light curtain, ensuring the normal operation of the light curtain, and thus improving the safety and stability of arc welding operations.

[0018] 4. High safety: The blackout curtain made of flame-retardant material can effectively block arc light and has flame-retardant properties, reducing the risk of fire and providing reliable safety for the working environment;

[0024] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0025] like Figure 1-3 The image shows a light-shielding device for a welding system, comprising a rodless cylinder 1, a fixed rod 4, a sliding paddle 6, and a light-shielding curtain 8. The rodless cylinder 1 and the fixed rod 4 are mounted on the threshold of the arc welding station. The rodless cylinder 1 is supplied with air from a gas source. A first end of the sliding paddle 6 is mounted on the slider of the rodless cylinder 1. The second end of the sliding paddle 6 and the light-shielding curtain 8 are slidably connected to the fixed rod 4. The working principle of the rodless cylinder is explained as follows: the piston maintains synchronized movement with the external slider through magnetic force. The load is mounted on the external slider. The piston compresses air to gain kinetic energy, thereby driving the external slider and the load to perform mechanical movement.

[0026] It also includes a solenoid valve; the solenoid valve is connected to the rodless cylinder 1, and both the solenoid valve and the rodless cylinder 1 are controlled by the arc welding robot system controller. The solenoid valve, connected to the rodless cylinder 1, precisely controls the on / off state and flow rate of the gas, achieving precise control of the rodless cylinder's movements. The solenoid valve is preferably a two-position, five-way, center-sealed type, requiring only a trigger signal to open and close. The arc welding robot system controller controls the arc welding robot system, the rodless cylinder 1, and the solenoid valve, respectively, achieving linkage between the closing and opening of the light-shielding curtain and the arc welding robot's welding operations. When the arc welding robot completes its arc welding operation, the rodless cylinder 1 drives the light-shielding curtain 8 to close slowly.

[0027] It also includes connector 2; connector 2 connects to rodless cylinder 1. Connector 2 is used for air inlet and outlet. The air inlet connector can be an adjustable flow connector. By adjusting the appropriate air inlet flow, low-speed closing is achieved to ensure smooth closing operation and avoid affecting the light curtain. High-speed opening function enables rapid opening and avoids affecting production cycle.

[0028] It also includes sliding rings 7; the top of the blackout curtain is slidably connected to the fixing rod 4 via several sliding rings 7. The sliding rings 7 can be selected as figure-eight buckle pull rings for hanging the blackout curtain 8; the fixing rod 4 is preferably a stainless steel rod; the sliding lever 6 has an overall L-shaped structure, and the connection between it and the blackout curtain 8 and the fixing rod 4 can adopt a figure-eight buckle structure. One sliding lever 6 is set on the left or right side of the blackout curtain 8. The blackout curtain 8 adopts a single-opening structure and can be opened to the left or right depending on the site conditions.

[0029] It also includes a counterweight 9; the bottom of the light-blocking curtain 8 is equipped with a counterweight 9. The weight of the counterweight 9 is used to prevent the light-blocking curtain from swaying when using equipment such as fans in summer, thus preventing interference with the light curtain.

[0030] It also includes cylinder mounting base 3; two cylinder mounting bases 3 are set on the threshold of the arc welding station, and the two ends of the rodless cylinder 1 are set on the two cylinder mounting bases 3; furthermore, the two cylinder mounting bases 3 are provided with slider buffer pads for the rodless cylinder 1, which are used to limit the movement stroke and realize deceleration and buffering, prevent slider impact, and ensure the accuracy and stability of the opening and closing action of the light-blocking curtain.

[0031] It also includes a fixing rod mounting base 5; the fixing rod mounting base 5 is set on the threshold of the arc welding station, the right side of the fixing rod 4 is set on the fixing rod mounting base 5, and the left side of the fixing rod 4 is fixed by the left cylinder mounting base 3.

[0032] The blackout curtain 8 is made of flame-retardant material. It can effectively block the arc light generated by arc welding and has flame-retardant properties, which greatly improves the safety during use.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
