DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] For example, see Figure 1-5 The present invention provides a technical solution: a suspension spot welding device convenient for welding various types of automobiles, comprising a suspension device 5, a processing device 3 is fixedly connected to the outer wall of the suspension device 5, a gas tank 4 is fixedly connected to the outer wall of the suspension device 5, a placement rack 2 is fixedly connected to the outer wall of the processing device 3, a spot welding device 1 is movably connected to the outer wall of the suspension device 5, and a weld detection mechanism 6 is fixedly connected to the outer wall of the suspension device 5; The weld detection mechanism 6 comprises: A bottom plate 61, the outer wall of the bottom plate 61 is fixedly connected to the outer wall of the suspension device 5; Black cloth 62, the black cloth 62 is fixedly connected to the top of the bottom plate 61; The slide rail 610, the outer wall of the slide rail 610 is connected to the outer wall of the placement rack 2 through a bracket, the outer wall of the slide rail 610 is slidably connected to an electric slider 611, and the outer wall of the electric slider 611 is fixedly connected to a direct light 612.

[0022] A camera device 69 is fixedly connected to the bottom of the slide rail 610 , and the camera device 69 faces the direction of the black cloth 62 .

[0023] A threaded plate 63 is fixedly connected to the outer wall of the bottom plate 61 . A threaded hole 64 is formed on the outer wall of the threaded plate 63 . A first bolt 65 is threadedly connected to the inner wall of the threaded hole 64 .

[0024] The outer wall of the first bolt 65 is further threadedly connected to a friction block 66 . The outer wall of the first bolt 65 is fixedly connected to a limit plate 67 . The outer wall of the limit plate 67 is threadedly connected to a second bolt 68 .

[0025] When in use, the automobile part to be welded is placed between the two limiting plates 67, and then the second bolt 68 on the limiting plate 67 is rotated to fix the automobile part. The first bolt 65 can switch multiple threaded holes 64, change the height of the two limiting plates 67, and then fix automobile parts of different shapes. Moreover, the rotation of the first bolt 65 can change the inclination angle of the limiting plate 67, and the automobile part is fixed by changing the angle. The suspension device 5 is connected to the spot welding device 1 through a pulling rope, and the spot welding device 1 is in a suspended state. Then, the automobile part is spot welded. The direct light 612 is set on the top of the automobile part, and then the black cloth 62 is set at the bottom. Under the irradiation of the direct light 612, the weld on the automobile part will pass through the light, and then the light will be displayed on the black cloth 62. On the left, the remaining weld can be observed. After welding is completed, the electric slider 611 is powered on and started to descend on the slide rail 610, which will drive the direct lamp 612 to descend. At this time, the descent of the direct lamp 612 will be close to the weld of the automobile part. Combined with the pinhole imaging principle, in pinhole imaging, there is a certain relationship between the object distance, that is, the distance from the direct lamp 612 to the weld and the image distance, that is, the distance from the black cloth 62 to the weld. When the object distance decreases, that is, the direct lamp 612 is close to the weld, the image distance will also decrease accordingly, but the size of the image will increase. This is because as the object distance decreases, more light can pass through the weld and be projected onto the screen, thereby increasing the size of the image. Then the camera device 69 shoots the black cloth 62, and the different sizes of the lights can make it easy for the staff to check it.

[0026] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The outer wall of the direct-light lamp 612 is fixedly connected with an auxiliary mechanism 7 . The auxiliary mechanism 7 includes a pipe 71 . The outer wall of the pipe 71 is fixedly connected to the outer wall of the direct-light lamp 612 .

[0027] An air flow opening 72 is formed at the bottom of the pipe 71 , and a first zigzag pipe 73 is fixedly connected to the outer wall of the pipe 71 .

[0028] A cleaning tube 74 is fixedly connected to the bottom of the first zigzag tube 73 , a spring 76 is fixedly connected between the outer wall of the cleaning tube 74 and the bottom plate 61 , and a second zigzag tube 75 is fixedly connected to the bottom of the cleaning tube 74 .

[0029] The outer wall of the second zigzag tube 75 is fixedly connected to a fan 77, and the outer wall of the fan 77 is connected to the suspension device 5 via a bracket. The inner part of the fan 77 is rotatably connected to a toggle rod 710. The outer wall of the cleaning tube 74 is fixedly connected to a gravity rod 78, and the outer wall of the gravity rod 78 is fixedly connected to an arc rod 79, and the toggle rod 710 is in movably contact with the arc rod 79.

[0030] When in use, the fan 77 is powered on and started. The fan 77 is connected to the pipeline 71 through the second zigzag pipe 75, the cleaning pipe 74 and the first zigzag pipe 73. Then the air flow is blown out from the air flow port 72, and the air flow is directly blown onto the automobile parts. The flow of the air flow will clean up the fallen welding slag to prevent the welding slag from blocking the welding seam position. The cleaning pipe 74 is set at the position of the black cloth 62. The cleaning pipe 74 blows out the air flow to the black cloth 62, and then cleans the welding slag fallen on the black cloth 62. Then the fan blades are rotated inside the fan 77, and the toggle rod 710 is driven to rotate during the rotation. The rotation of the toggle rod 710 will toggle the arc rod 79, and then pull the cleaning pipe 74 to shake. The subsequent spring 76 can drive the cleaning pipe 74 to reset under its own elasticity. The fluctuation of the toggle rod 710 on the arc rod 79 drives the cleaning pipe 74 to change its angle. At this time, the cleaning pipe 74 changes its angle to blow air onto the black cloth 62 to clean the welding seam on the black cloth 62.

[0032] A camera device 69 is fixedly connected to the bottom of the slide rail 610 , and the camera device 69 faces the direction of the black cloth 62 .

[0034] In practical applications, an image processor is also provided to process the video frames captured by the direct light 612 in real time and extract key information such as the outline and area of ​​the projection; The outer wall of the first bolt 65 is also threadedly connected to a friction block 66, the outer wall of the first bolt 65 is fixedly connected to a limit plate 67, and the outer wall of the limit plate 67 is threadedly connected to a second bolt 68; The principle of pinhole imaging. In pinhole imaging, there is a certain relationship between the object distance, that is, the distance from the direct light 612 to the weld, and the image distance, that is, the distance from the black cloth 62 to the weld. When the object distance decreases, that is, the direct light 612 approaches the weld, the image distance will also decrease accordingly, but the size of the image will increase. This is because as the object distance decreases, more light can pass through the weld and be projected onto the screen, thereby increasing the size of the image.
