Description

Technical Field

[0001] The invention relates to the technical field of welding robots, in particular to a welding robot capable of real-time quality monitoring. Background Art

[0002] The welding robot with real-time quality monitoring is a robot used to perform welding tasks in the field of industrial automation. It uses thermal imaging sensors to collect welding information in real time, analyzes the collected welding information, and performs real-time detection of welding quality to ensure that the welding quality meets the standards.

[0003] In the prior art, the traditional welding robot with real-time quality monitoring liberates manpower and protects the workers through automatic welding. However, when welding objects, the welding robots in the existing designs will still splash the debris generated in the workshop, polluting the workshop environment. Welding will generate a lot of heat and gas, and there are many harmful gases in the gas. The existing welding robots are not equipped with a device to filter the welding gas, which causes the welding gas to diffuse into the working environment. Long-term exposure to this welding will cause damage to the respiratory health of the workers. Summary of the invention

[0004] The object of the present invention is to provide a welding robot capable of real-time monitoring of quality, so as to solve the problems mentioned in the above background technology.

[0007] Preferably, a first telescopic groove is opened around the bottom of the protective cover, a first spring is arranged in the first telescopic groove, and a telescopic ring is arranged at the bottom of the first spring. The telescopic ring can be telescoped in the first telescopic groove through the first spring, so that the protective cover and the telescopic ring cover the welding point around to prevent debris and smoke from splashing in the workshop environment.

[0009] Preferably, a through hole is provided in the middle of the bottom of the filter assembly, and the filter assembly is communicated with the thermal imaging sensor through the through hole. An air intake port is provided in the middle of the top of the filter assembly, and the air intake port is connected to the exhaust fan through a hose. The outlet of the exhaust fan is connected to the gas collecting tank through a connecting pipe, and the exhaust fan can draw the smoke into the gas collecting tank for collection.

[0010] Preferably, the filter assembly is provided with a baffle at the bottom of the filter screen. The baffle is frustum-shaped and hollow in the middle. The baffle can block impurities filtered out by the filter screen to prevent the impurities from falling on the inner bottom of the filter assembly. The filter assembly is provided with leakage grooves around the bottom of the baffle, and connecting columns are provided in the leakage grooves. The connecting columns connect the bottom of the filter assembly with the top of the filter assembly.

[0011] Preferably, the filter assembly is provided with a third telescopic groove at the top of the leakage groove, a third spring is provided in the third telescopic groove, and the bottom of the third spring is connected to a closed ring, which can close the leakage groove to prevent the sucked smoke from escaping from the leakage groove.

[0012] Preferably, the two outer ends of the top end of the leakage groove are connected to a toggle block, which extends from the third telescopic groove. Pushing the toggle block upward can shrink the closed ring into the third telescopic groove, open the closure of the leakage groove, and allow the debris on the baffle to roll down the inclined surface of the baffle and be discharged from the leakage groove.

[0013] Preferably, a connecting rope is inserted into the side of the top end of the filter assembly, the inner end of the connecting rope is connected to the counterweight ball in the limiting cavity, and the outer end of the connecting rope is provided with a counterweight ball.

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

[0015] The present invention provides a welding robot capable of real-time quality monitoring. When the welding robot is welding, the mechanical arm starts to control the welding assembly to move to the welding point, and the protective cover covers the welding point. The telescopic ring expands and contracts in the first telescopic groove by squeezing the first spring, so that the protective cover and the telescopic ring cover and seal the welding point to prevent the smoke generated by welding from drifting. Then, the exhaust fan is started, and the exhaust fan starts to inhale the thermal imaging sensor connected to the through hole at the bottom of the filter assembly through the air intake port. At the same time, the welding assembly starts to weld, and the top air intake channel inside the filter assembly starts to collect welding information by thermal imaging, and the welding information is detected in real time. The inhaled smoke and debris enter the filter assembly along the thermal imaging sensor. At this time, the filter starts to filter the smoke, leaving the debris particles in the smoke at the bottom of the filter. At this time, the debris falls on the baffle at the bottom of the filter by gravity, and the inhaled smoke is pumped into the gas collecting tank through the air intake port for collection, so as to prevent the smoke from spreading to the working environment and causing harm to the respiratory health of the staff.
