Referring to fig. 1, the welding system for automatically detecting the quality of the surface of a weld seam according to the embodiment includes a welding robot 11, a welding gun 6 mounted on the welding robot 11, a welding detection sensor 5 and a display 2. The welding detection sensor 5 is positioned behind the welding gun 6 and used for measuring the actual quality parameters of the welding seam obtained by welding of the welding gun 6; the display 2 is connected with a welding detection sensor 5 and displays the actual quality parameters of the welding seam.
According to the welding system for automatically detecting the surface quality of the welding seam, the welding detection sensor 5 is positioned behind the welding gun 6, so that a process of welding firstly and detecting secondly is formed. The welding system for automatically detecting the surface quality of the welding seam changes the original manual detection of the surface quality of the welding seam into automatic detection, does not need manual participation, can realize the detection while welding, further improves the detection efficiency and shortens the detection time. The surface quality detection of the manual welding seam is basically carried out after the welding is finished. In addition, the welding system for automatically detecting the surface quality of the welding seam records continuous welding seam surface quality information and can output images; whereas the manually recorded weld surface is discrete and non-continuous.
The welding detection sensor 5 may be a linear laser sensor, a linear array camera, an infrared sensor, or the like in the prior art. For example, when the welding detection sensor 5 is a line laser sensor, laser is emitted to the weld, and the position information of each point on the surface of the weld is obtained, so as to finally obtain the overall profile of the weld, and the quality of the weld, such as whether a pit, a protrusion, an undercut, or the like exists, can be judged based on the profile of the weld. For another example, when the welding detection sensor 5 is a line camera, the line camera continuously scans the weld line by line, so as to achieve the purpose of uniformly detecting the whole surface of the weld line. The line camera may process a weld image line by line, or an area image composed of multiple lines. In addition, the linear array camera is very suitable for the measuring occasion, has high resolution and can accurately measure the micrometer.
In one embodiment, the welding system for automatically detecting the surface quality of a weld seam further comprises a first processing module. The first processing module obtains the actual quality parameters and establishes the corresponding relation between the actual quality parameters and the positions of the welding seams.

In one embodiment, the welding system for automatically detecting the surface quality of the welding seam further comprises an alarm module and a positioning module. The alarm module sends out an alarm signal based on the difference between the actual quality parameter and the theoretical quality parameter, and when the difference between the actual quality parameter and the theoretical quality parameter is larger than the maximum error tolerance value, the alarm module sends out the alarm signal to prompt that the current welding seam quality is not in line with the requirement and needs to be adjusted. Specifically, the alarm module may be connected to the welding detection sensor 5 to obtain an actual quality parameter, and the difference between the actual quality parameter and the theoretical quality parameter is compared in the alarm module to determine whether the difference is greater than the maximum error tolerance value. The alarm module can also be connected with a judgment module mentioned later, so that the alarm module directly obtains the comparison result between the actual quality parameter and the theoretical quality parameter and sends out an alarm signal based on the comparison result. The positioning module positions the corresponding welding seam position when the alarm signal is sent out, and controls the welding gun 6 to move to the welding seam position corresponding to the alarm signal based on the positioning information. After the welding gun 6 moves to the position of the welding seam corresponding to the alarm signal, the welding seam quality can be adjusted, so that the welding seam meets the welding requirement.
Similarly, the alarm module can adopt an alarm single chip microcomputer disclosed in the prior art. The positioning module can adopt a singlechip with a positioning function disclosed in the prior art. After the positioning module positions the position of the welding seam corresponding to the alarm signal, the welding gun 6 can be controlled to move to the position.
Wherein, the actual quality parameters measured by the welding detection sensor 5 include the weld section contour line. In this case, the theoretical quality parameter is also the theoretical cross-sectional contour 19 of the theoretical weld seam. By comparing the actual cross-sectional contour line of the weld with the theoretical cross-sectional contour line 19 of the weld, please refer to fig. 2, it can be directly judged whether the quality of the weld meets the requirements.

When the surface quality is automatically detected, the welding detection sensor 5 scans the actual section contour line of the welding seam of the workpiece 4 in real time, compares the actual section contour line with an upper deviation line 20 and a lower deviation line 21 of the welding section, and records the quality problem and gives an alarm if the actual section contour line is out of tolerance. And actual parameters such as the sizes A and B of weld legs of the welding seam can be output in real time.
Further, the welding system for automatically detecting the surface quality of the welding seam also comprises a judging module. The judging module obtains the actual quality parameters, compares the actual quality parameters with the theoretical quality parameters, and obtains the weld defect types based on the comparison, wherein the defect types include pits 16, bulges 17 or undercuts 18, please refer to fig. 3 to 5. Similarly, the judging module can adopt a single chip microcomputer with a judging and comparing function in the prior art.

That is, by providing the position adjusting mechanism 15, the welding detection sensor 5 can realize different detection functions.
The position adjusting mechanism 15 may be a turntable that is rotatable with respect to the welding torch 6. Further, as the turntable rotates, the welding detection sensor 5 mounted on the turntable also rotates to a different position of the welding torch 6. For another example, the position adjusting mechanism 15 may be a rocker arm, a hinge, or the like, as long as the welding detection sensor 5 can be driven to move to different positions of the welding gun 6.
