[0002] Spot welding machine is a kind of mechanical equipment, which adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, an instantaneous heat welding is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the workpiece being welded.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, an embodiment of the utility model provides a visual device for realizing real-time safety monitoring in a fixed spot welding machine, comprising: a spot welding machine body 1, the spot welding machine body 1 comprising: a supporting part 101, a dispensing part 102 and a placing part 103; a fixed plate 7, arranged between the dispensing part 102 and the placing part 103; a camera device 13, arranged on the fixed plate 7; a placing cover 8, arranged on the fixed plate 7, and the camera device 13 is located in the placing cover 8, for protecting the camera device 13; a monitoring hole 12, arranged on the placing cover 8; a placing frame 10, arranged on the fixed plate 7 through a fixing block; a driving part 9, arranged on the placing cover 8, the driving part 9 comprising: a small motor 91, arranged on the placing cover 8 through an L-shaped support strip; a filter body 92, arranged on the output end of the small motor 91.

[0027] By setting the filter body 92, the filter body 92 can adopt a polarizing filter, which can effectively reduce reflected light and glare, and is particularly suitable for eliminating strong light caused by metal surface reflection and welding sparks, enhancing image contrast and clarity, and can also adopt a variable density filter, and the transmittance can be adjusted as needed to adapt to the light conditions of different welding stages; the camera device 13 has an automatic exposure control function, and dynamically adjusts the exposure time or gain according to the actual light conditions of the welding area to balance the overexposure and underexposure problems, and the image processing system.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, it also includes: a placement groove is set at the center of the placement frame 10, and matches the filter body 92. By setting the placement frame 10, the design is cylindrical, which is convenient for placing the filter body 92 and plays a protective role on the filter body 92 when not working.

[0029] like Figure 2 and Figure 3 As shown, it also includes: a plurality of vents 11, which are arranged on the placement cover 8, for heat dissipation when the camera device 13 is used.
