Technical Field

[0001] This utility model relates to the field of electric welding machine technology, specifically an energy-saving electric welding machine. Background Technology

[0002] Laser welding machines, also known as laser welding machines or laser welding machines, are machines used for processing laser materials. They are highly automated and have a simple welding process. According to their working method, they are divided into laser mold welding machines, automatic laser welding machines, laser spot welding machines, and fiber optic transmission laser welding machines, etc.

[0003] Unlike fully automated laser welding machines, handheld laser welding guns pose certain dangers to the operating area due to the influence of manual operation. When the welding gun is placed on the ground or on the worktable while it is powered on, it can be easily triggered by external factors, which not only continuously increases energy consumption but also poses a great safety hazard.

[0004] In view of this, an energy-saving welding machine was designed to solve the above problems. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0033] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0034] The following describes, with reference to the accompanying drawings, some embodiments of an energy-saving welding machine provided by this utility model. Example 1

[0035] Combination Figures 1-5As shown, the present invention provides an energy-saving welding machine, including a laser welding gun 100, an intermittent protection mechanism 200 disposed on the laser welding gun 100, a controller 300 disposed on the intermittent protection mechanism 200, a detection mechanism 400 disposed on the laser welding gun 100, and a contact wire 500 disposed on the intermittent protection mechanism 200. The detection mechanism 400 is used to perform physical detection on the workpiece to be welded and convert it into an electrical signal and transmit it to the controller 300. The controller 300 is used to control the current input to the laser welding gun 100 by the contact wire 500 to be turned on and off. The intermittent protection mechanism 200 is used to cooperate with the controller 300 to effectively input and output the current.

[0036] The intermittent control and protection mechanism 200 includes a base 230, an insulating sleeve 240 disposed inside the base 230, a plug 250 installed at the inner end of the insulating sleeve 240, a socket 260 installed at the outer end of the insulating sleeve 240, and a spring 270 disposed between the plug 250 and the spring 270.

[0037] An input wire 280 is connected to the socket 260, and an output wire 290 is connected to the plug 250. The bottom ends of the input wire 280 and the output wire 290 are connected to the connectors on the top of the controller 300.

[0038] The detection mechanism 400 includes a core wire 450 connected to the controller 300, an infrared probe 440 connected to the other end of the core wire 450, a ring 410 mounted on the laser welding gun 100, two bases 420 mounted on the ring 410, a limiting cover 430 mounted on the ring 410, and a baffle 470 movably mounted inside the limiting cover 430.

[0039] The bottom of the baffle 470 is equipped with a sliding plate, and the sliding plate has a limit track inside, and the track is equipped with a counterweight 480.

[0040] A protective tube 210 is installed inside the laser welding gun 100, a clamp 220 is installed at one end of the protective tube 210, and the other end of the protective tube 210 is installed on the infrared probe 440.

[0041] The inside of the protective tube 210 is provided with a through hole adapted to constrain the core wire 450.

[0042] When the laser welding gun 100 is held by the user and approaches the object to be welded, as the welding head of the laser welding gun 100 is vertically upward, the counterweight 480, which is under weight, will exert downward pressure on the baffle 470. At this time, the baffle 470 will be removed from inside the limit cover 430 and the end of the infrared probe 440 will be exposed. As the infrared probe 440 projects infrared rays onto the object to be welded, at the moment of detection, the infrared probe 440 can transmit the electrical signal to the controller 300. Finally, the controller 300 can transmit the current input from the contact wire 500 to the plug 250, and the plug 250 can supply power to the laser welding gun 100.

[0043] At this time, the laser welding gun 100 can ensure that the infrared rays are in real-time contact with the workpiece during the longitudinal tilt welding process. When the welding operation is completed and the laser welding gun 100 is placed horizontally, the baffle 470 will be quickly reset by the pressure of the sealing plate 462. Finally, the baffle 470 can seal the inner cavity of the limit cover 430. When the infrared rays are blocked, the controller 300 can disconnect the current input from the contact wire 500 to the plug 250, thereby ensuring the safety of the laser welding gun 100 during standby and reducing energy consumption during standby. Example 2

[0044] Combination Figure 3 and Figure 5 As shown, based on Embodiment 1, both the inner and outer walls of the insulating sleeve 240 are coated with an insulating varnish layer, and lead wire slots are provided at the bottom of both ends of the insulating sleeve 240.

[0045] The spring 270 is provided with an insulating outer sheath;

[0046] The controller 300 is equipped with a short-circuit protection fuse tube. The input end of the fuse tube forms a connection path with the input wire 280, and the output end of the fuse tube forms a connection path with the output wire 290.

[0047] Preferably, the spring 270 with an external insulating sheath can apply a stabilizing elastic support force to the plug 250 and the socket 260. When the terminal post at the top of the contact wire 500 is inserted into the socket 260, the plug 250 and the socket 260, which are in a stabilizing state, can ensure the overall stability of the contact wire 500, the base 230 and the laser welding gun 100 after assembly.

[0048] The contact wire 500 has a threaded groove at one end facing the base 230, and a pole post is provided at the middle of the top of the contact wire 500, which is adapted to penetrate into the interior of the socket 260.

[0049] Preferably, the inner wall of the socket 260 is provided with a tubular inner pad, and the tubular inner pad is connected to the top of the input wire 280. After the top pole of the contact wire 500 is inserted into the tubular inner pad inside the socket 260, the current input by the contact wire 500 can maintain an absolutely safe current path to ensure the stability of the real-time power supply of the laser welding gun 100. Example 3

[0050] Combination Figure 3 and Figure 4 As shown, in the above embodiment, the detection mechanism 400 further includes a reset component 460;

[0051] The reset assembly 460 includes a clamp 461 mounted on one end of the infrared probe 440 extending to the outside of the ring 410, and a sealing plate 462 mounted on the bottom end of the clamp 461.

[0052] The clamp 461 has a sliding groove inside, and a compression spring 463 is installed in the sliding groove.

[0053] Preferably, the sealing plate 462 can be fixed to the bottom end of the clamp 461 by welding or bolts, while the bottom end of the compression spring 463 is fixedly installed on the top of the sealing plate 462, and the top end of the compression spring 463 is adapted to bear pressure on the slide plate at the bottom of the baffle 470.

[0054] A nut is provided on the threaded section at the top of the counterweight 480, and a deposit slide is provided on the outside of the threaded section.

[0055] The working principle and usage process of this utility model: When the user holds the handle of the laser welding gun 100 and controls the welding head of the laser welding gun 100 to be vertically upward, the counterweight 480 will be located directly below the welding head of the laser welding gun 100. At this time, the baffle 470, under the pressure of gravity, will fall down under the pressure of the counterweight 480 until the bottom slide of the baffle 470 moves to the bottom of the inner groove of the clamp 461 and is effectively supported by the sealing plate 462. At this time, the laser welding gun 100 can ensure that the infrared probe 440 rays are always projected onto the surface of the item to be welded during the downward tilt angle or horizontal adjustment of the welding head.

[0056] As the core wire 450 converts the detection signal into an electrical signal, the controller 300 can instantly input the current transmitted by the contact wire 500 from the socket 260 into the input wire 280 upon receiving the electrical signal. Finally, the current will be output from the output wire 290 to the plug 250, and the plug 250 can continuously input the current into the laser welding gun 100.

[0057] When welding is temporarily stopped and the laser welding gun 100 is placed horizontally on the workbench or the ground, the baffle 470, which is no longer under the load of the counterweight 480, will be quickly pushed back up by the compression spring 463 until the baffle 470 is resealed in the inner cavity of the limit cover 430. When the baffle 470 blocks the infrared rays of the infrared probe 440, the controller 300, which loses the electrical signal, will disconnect the current output from the contact wire 500 to the output wire 290 and the plug 250. At this time, the laser welding gun 100 can be in a horizontal, power-off, energy-saving state.

[0058] 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.
