It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] See Figures 1 - 4 , the purpose of the present utility model is to provide an automatic welding position and quality detection device, including a base 1, on which a rotary cylinder 2, a gantry 4 and a support table 6 are installed; the output end of the rotary cylinder 2 faces upward, and the output end is fixedly connected to a mounting table 3 through a rotating table 20, and a mounting clamp 32 is fixedly connected to the mounting table 3.

[0025] A lamp group is installed on the gantry 4, and the light of the lamp group faces the mounting clamp 32. An industrial camera 7 is fixedly connected to the support table 6, and the lens of the industrial camera 7 and the mounting clamp 32 are arranged on the same plane.

[0026] Preferably, a chute 10 is provided on the base 1, and the bottom of the rotary cylinder 2 is fixedly connected to a slider 21, and the slider 21 is slidably connected inside the base 1. Thus, the rotary cylinder 2 can adjust the distance from the industrial camera 7 in this way, and when inspecting strip springs of different sizes, the entire strip spring can be photographed at a suitable position in the camera screen, facilitating more accurate inspection of it.

[0027] Preferably, several screw holes leading to the chute 10 are provided on one side of the base 1. A screw 11 is threadedly connected in the screw hole, and a knob 12 is fixedly connected to the end of the screw 11 away from the chute 10. During use, the staff can loosen the abutment of the screw 11 against the slider 21 through the knob 12, move the rotary cylinder 2, and then install the screw 11 in the screw hole corresponding to the slider 21 to fix the position of the rotary cylinder 2.

[0028] Preferably, several mounting clips 32 are provided on the top of the mounting table 31, and the several mounting clips 32 are arranged in a comb shape at equal intervals on the top of the mounting table 31.

[0029] Preferably, an end block 311 is fixedly connected to one end of the mounting table 31. The end block 311 has a limiting function to ensure that the installation positions of each strip are the same during installation, making it more convenient for the computer to identify the solder joints shown in the captured pictures.

[0030] Preferably, two lamp groups are fixedly connected to the gantry 4, namely a first lighting lamp group 51 and a second lighting lamp group 52, and the light-emitting ends of the first lighting lamp group 51 and the second lighting lamp group 52 both face the mounting clip 32. Specifically, the first lighting lamp group 51 is located above the second lighting lamp group 52 and at a certain distance from the second lighting lamp group 52, so that the lens sight line of the industrial camera 7 passes through the space between the first lighting lamp group 51 and the second lighting lamp group 52. The first lighting lamp group 51 and the second lighting lamp group 52 can provide more sufficient illumination.

[0031] Preferably, the lamp group is connected to the gantry 4 through a fastening knob 41; specifically, one end of the lamp group is rotatably connected to the gantry 4, a screw hole is provided at the other end of the lamp group, and the threaded rod on the fastening knob 41 passes through the gantry 4 and is threadedly connected in the screw hole, so that the angle of the lamp group can be adjusted by loosening or tightening the fastening knob 41.

[0032] Preferably, a supporting plate 61 is installed on the support table 6, and the industrial camera 7 is installed on the supporting plate 61, and several industrial cameras 7 are installed on the supporting plate 61. The supporting plate 61 is used to install multiple industrial cameras 7, and the multiple industrial cameras 7 can take front views of the solder joints to ensure the accurate identification of multiple solder joints.

[0033] Preferably, a wire clip 62 is fixedly connected to one side of the support table 6. The wire clip 62 can play a role in fixing the power cord and the signal line, facilitating wire management and making the equipment tabletop cleaner.

[0034] Preferably, the lamp group includes a lamp group housing 71 and bulbs 72 installed on the lamp group housing 71; several bulbs 72 are installed on the lamp group housing 71, and the several bulbs 72 can form the effect of a shadowless lamp, making the shooting of the solder joints clearer.

[0035] In summary, during actual use, by setting the industrial camera 7 and the strip inspection mounting jig (i.e., the mounting clip 32 on the mounting table 3) at fixed positions, the strip inspection mounting jig has a unified strip mounting position reference. At the same time, driven by the rotating cylinder 2, the strip inspection mounting jig has a 180° rotation function. Through the rotation of the jig, both surfaces of the spring welding can be fully inspected; the camera's field of view fully covers the positions of the welded spring and the welding position that need to be detected. The camera collects picture information and sends it to an external computer terminal. The computer judges the non-conformity of the collected picture information through methods such as machine vision and deep learning. Specifically, to inspect the welding quality, the limit samples and other non-conformity information are collected in advance, the non-conformities are marked through internal marking in the computer, and finally, the welding quality non-conformities are processed internally in the program by using machine vision and AI vision learning methods. Subsequently, the computer judges the welding point non-conformities by identifying the photos.

[0036] Certainly, the present utility model may also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
