An anti-spatter industrial welding robot

Abstract

This utility model relates to the field of welding equipment technology and discloses an anti-spatter industrial welding robot, including a base, a mechanical wall on the top of the base, and a first electric push rod on the outside of the mechanical wall. This anti-spatter industrial welding robot, through the installation of protective components, activates a stepper motor that drives a threaded rod to rotate via an output shaft. The cooperation between the threaded rod and a supporting connecting plate allows a protective sleeve to move upwards to shield the welding table. When the supporting connecting plate reaches its highest point, rotating two threaded shafts causes a limiting block to engage with a limiting groove to limit the protective sleeve. This, combined with the annular limiting groove at the bottom of the cover plate, forms a top seal, completely covering the area surrounding the welding table. This effectively prevents spatter from splashing from the top, sides, and other blind spots of traditional fixed baffles, avoiding wear on equipment parts and the risk of burns to personnel, improving the practicality of the device and facilitating its use by workers.

Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an anti-spatter industrial welding robot. Background Technology

[0002] Welding robots are industrial robots that perform welding work. Welding is a common industrial processing method that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics in a manufacturing process.

[0003] Existing anti-spatter protection systems for industrial welding robots have significant technical shortcomings: traditional protective devices mainly consist of fixed metal baffles, which can only provide physical shielding at a fixed angle to the welding area. This allows spatter to fly through blind spots such as the top and sides, causing damage to the equipment or burns to workers. Furthermore, most welding robots do not have fume purification functions, and welding fumes can easily affect the working environment. Therefore, an anti-spatter industrial welding robot is proposed to solve the aforementioned technical problems. Utility Model Content

[0029] In summary, this anti-spatter industrial welding robot, by setting up a protective component 6, starts a stepper motor 61 that drives a threaded rod 62 to rotate via its output shaft. The cooperation between the threaded rod 62 and the support connecting plate 63 allows the protective sleeve 64 to move upward and block the welding table 5. When the support connecting plate 63 moves to its highest position, the rotation of the two threaded shafts 72 drives the limiting block 73 to cooperate with the limiting groove to limit the protective sleeve 64. This, together with the annular limiting groove at the bottom of the cover plate 11, forms a top seal, completely covering the area around the welding table 5. This effectively prevents spatter from splashing from the top, sides, and other blind spots of traditional fixed baffles, avoiding wear on equipment parts and the risk of burns to personnel, thus improving the practicality of the device. By setting up a suction component 8, the suction fan 83 removes the welding fumes through the suction... The smoke pipe 82 draws the smoke into the purification chamber 81. The activated carbon filter inside the purification chamber 81 filters the metal oxide particles and harmful gases in the welding fumes. The filtered gas is then exhausted. The replacement door on the rear side wall of the purification chamber 81 facilitates the regular replacement and maintenance of the filter element, meeting industrial environmental protection requirements, improving the working environment, protecting the health of operators, and further enhancing the practicality of the device. This solves the significant technical shortcomings of the existing anti-spatter protection system for industrial welding robots: traditional protective devices are mainly fixed metal baffles, which can only form a fixed-angle physical shielding of the welding area, causing spatter to splash through blind spots such as the top and sides, damaging the equipment or burning the workers. Secondly, most welding robots do not have fume purification functions, and welding fumes can easily affect the working environment.
