[0029] like Figure 1 - Figure 5 As shown, a gas shielded welding machine with wire feeding auxiliary lighting according to a first aspect embodiment of the present invention includes a welding machine body. The welding machine body includes a housing 100, a cover 200, a wire feeding assembly 300, an lighting module 400, and a detection assembly 500. The housing 100 has an open cavity. The cover 200 is movably connected to or detachably connected to the housing 100. The cover 200 can close the opening or open the cavity. The wire feeding assembly 300 is disposed in the housing 100 and located in the cavity. The lighting module 400 is disposed in the housing 100 and located in the cavity. The light-emitting end of the lighting module 400 faces the wire feeding assembly 300. The detection assembly 500 is disposed in the housing 100. The detection assembly 500 is used to detect the on / off state of the cover 200 to generate a trigger signal. The detection assembly 500 is connected to the lighting module 400 so that the lighting module 400 is triggered to light up by the trigger signal when the cover 200 is opened.

[0030] The shell 100 can be formed by sheet metal parts made of alloy material. The shell 100 can be rectangular or cylindrical, etc. In some embodiments of this utility model, the opening is provided on the side of the shell 100, and the cover 200 is rotatably connected to the shell 100 so that the cover 200 can close the opening or open the cavity by flipping.

[0031] Alternatively, in some embodiments of this utility model, the cover 200 can also be detachably mounted on the housing 100 by a snap fastener. The user can unfasten the snap fastener to separate the cover 200 from the housing 100, thereby opening the cavity.

[0032] This utility model relates to a gas shielded welding machine with wire feeding auxiliary lighting. The wire feeding assembly 300 is located in the cavity and provides welding wire to the welding assembly. When the user needs to thread the welding wire through the wire feeding assembly 300, the cover 200 can be opened. At this time, the detection assembly 500 detects the opening of the cover 200 and generates a trigger signal. The trigger signal triggers the lighting module 400 to light up. The light-emitting end of the lighting module 400 shines towards the wire feeding assembly 300, and the user can clearly see the positional relationship between the welding wire and the wire feeding assembly 300, which is convenient for threading the wire. This design can provide lighting in the cavity, which is convenient for completing the wire threading operation and is easy and reliable to use.

[0033] In some embodiments of this utility model, such as Figure 1 As shown, the detection component 500 includes a normally closed touch switch. Applying force to the normally closed touch switch can cause it to open. The normally closed touch switch is disposed in the housing 100. The cover 200 closes the opening and presses against the normally closed touch switch. The power supply is connected to the lighting module 400 through the normally closed touch switch.

[0034] The detection component 500 can be located near the connection between the housing 100 and the cover 200. When the cover 200 closes the opening, it can press against the normally closed touch switch, thereby causing the normally closed touch switch to open and disconnecting the power supply to the lighting module 400, turning off the lighting module 400. When the cover 200 is open relative to the housing 100, the normally closed touch switch loses the pressure of the cover 200, closes, and restores the power supply to the lighting module 400, turning on the lighting module 400.

[0035] Alternatively, in some embodiments of this utility model, the detection component 500 may also include a position sensor and a controller. The position sensor may be an infrared sensor, a capacitive sensor, a lidar, an ultrasonic sensor, etc. The controller may be selected from an MCU or a CPU and its auxiliary circuits. The position sensor detects the position of the cover 200 and generates a feedback signal. The controller may control the lighting module 400 to turn on or off according to the feedback signal.

[0036] In some embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the housing 100 has a vertical plate 110 in the cavity, and the lighting module 400 protrudes from the vertical plate 110 and is located above the wire feeding assembly 300.

[0037] Specifically, the housing 100 also contains some welding components. The wire feeding assembly 300 and the welding assembly are conventional components of the gas shielded welding machine, which will not be described in detail here. The upright plate 110 divides the space of the cavity. One side of the upright plate 110 can be used to place the wire feeding assembly 300 and the welding assembly. The other side of the upright plate 110 is equipped with a control circuit board for controlling the operation of the wire feeding assembly 300 and the welding assembly. The lighting module 400 protrudes from the upright plate 110 and can be located above the wire feeding assembly 300 and project towards the wire feeding assembly 300.

[0038] In some embodiments of this utility model, the lighting module 400 includes a bracket 410 and a lamp plate 440. The lamp plate 440 is mounted on the bracket 410 via a snap-fit ​​structure 600, and the bracket 410 is detachably mounted on the upright plate 110.

[0039] The lamp board 440 can be a conventional LED lamp board 440, and LED beads 450 can be set on the lamp board 440. The lamp board 440 can be installed on the bracket 410, and the bracket 410 is then installed on the upright plate 110, so that the light-emitting end of the lamp board 440 can protrude towards the wire feeding assembly 300.

[0040] In some embodiments of this utility model, such as Figure 4 , 5 As shown, one end of the bracket 410 is provided with a mounting groove 420, and the bracket 410 is provided with a light outlet 430 penetrating the upper and lower end surfaces on the bottom surface of the mounting groove 420. The lamp board 440 is provided with lamp beads 450, and the lamp board 440 is disposed in the mounting groove 420 and the lamp beads 450 are located in the light outlet 430.

[0041] The lamp board 440 is embedded in the mounting groove 420. The wires connecting the lamp board 440 can be led out from the notch on one side of the mounting groove 420, and the lamp beads 450 can be exposed from the light outlet 430.

[0042] Specifically, the snap-fit ​​structure 600 includes an abutment post 610 disposed on the bottom surface of the mounting groove 420 and an undercut 620 disposed on the side surface of the mounting groove 420. The abutment post 610 abuts against the lower end surface of the lamp panel 440, and the undercut 620 engages with the upper end surface of the lamp panel 440. The undercut 620 and the abutment post 610 cooperate to clamp the upper and lower end surfaces of the lamp panel 440, thereby restricting the lamp panel 440 from moving up and down. The inner wall of the mounting groove 420 can restrict the lamp panel 440 from moving left and right, ensuring that the lamp panel 440 is securely installed.

[0043] In some embodiments of this utility model, the bracket 410 is provided with a reflective inclined surface 431 around the light outlet 430. The reflective inclined surface 431 is arranged around the outer periphery of the lamp bead 450 to form an annular surface. The reflective inclined surface 431 gradually expands outward from the direction close to the lamp bead 450 to the direction far away from the lamp bead 450. Some of the light emitted by the lamp bead 450 can be reflected by the reflective inclined surface 431 and then emitted, thereby forming a converging light that is projected onto the wire feeding assembly 300.

[0044] In some embodiments of this utility model, such as Figure 2 , Figure 4 , Figure 5 As shown, the other end of the bracket 410 is provided with a first mounting hole 710, and the upright plate 110 is provided with a second mounting hole 720. Screws 730 are respectively inserted into the first mounting hole 710 and the second mounting hole 720 so that the bracket 410 can be detachably installed on the upright plate 110.

[0045] When assembling the bracket 410, align the first mounting hole 710 and the second mounting hole 720, and then use screws 730 to pass through the first mounting hole 710 and the second mounting hole 720 respectively, thereby fixing the bracket 410 to the upright plate 110. The installation is convenient and the disassembly is simple.

[0046] In some embodiments of this utility model, the other end of the bracket 410 is provided with a guide post 750, and the upright plate 110 is provided with a guide hole 740. The guide post 750 can be inserted into the guide hole 740 so that the first mounting hole 710 and the second mounting hole 720 are aligned.

[0047] Specifically, there can be at least two guide posts 750, and the number of guide holes 740 is matched one-to-one with the number of guide posts 750. Before the bracket 410 is installed on the upright plate 110, the user can first insert the guide posts 750 into the guide holes 740 one-to-one, so that the first mounting hole 710 and the second mounting hole 720 are aligned. Then, the screws 730 are installed, making the installation more convenient and reliable. After installation, the cooperation between the guide posts 750 and the guide holes 740 can make the bracket 410 and the upright plate 110 more securely installed.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
