Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a novel mobile welding robot. Background Art

[0002] With the development of welding technology and intelligent robots, intelligent welding robots with mobile functions have developed rapidly. For example, the mobile intelligent consumable gas shielded welding robot (hereinafter referred to as the mobile welding robot) is a multi-axis robot that uses the control software system and working mode in the upper computer as a motion carrier. When working, under the action of relevant equipment, the forearm of the multi-axis robot drives the front end of the welding nozzle of the welding gun close to the base material to be welded, and the wire feeder feeds the welding wire continuously output by the wire feeder reel through the guide tube (the wire feeder reel is wound with multiple turns of welding wire, and the center hole of the wire feeder reel rotates and is sleeved on the rotating shaft at the rear end of the equipment. The welding wire on the wire feeder reel is continuously input into the welding gun through the wire feeder and the guide tube) into the front end of the forearm of the multi-axis robot. In the welding gun, the welding wire is continuously fed out from the front end of the welding nozzle by the wire feeder to approach the base material to be welded. The electric arc generated between the fusible welding wire and the base material weldment is used as the heat source to melt the welding wire and the base metal (the carbon dioxide bottle in the shell of the mobile welding robot delivers protective gas to the welding area to protect the arc, molten welding wire, molten pool and nearby base metal from the harmful effects of the surrounding air, thereby achieving better welding effect), thereby welding the corresponding parts of the base metal parts together (the staff pulls or pushes the equipment to the relevant work station through the upper handle of the mobile welding robot).

[0003] Although the existing mobile welding robots meet the work needs to a certain extent, due to structural limitations, the remaining amount of welding wire on the wire feeding reel needs to be checked by the staff from time to time. In this way, when the welding wire is used up due to various reasons (including irresponsible work, etc.) and the staff does not observe and replace the new wire feeding reel in time, it will have an adverse effect on the normal welding work and is not conducive to improving work efficiency. In summary, it is very necessary to provide a mobile welding robot that not only has all the other same functions of an ordinary mobile welding robot, but also can monitor the remaining amount of welding wire on the wire feeding reel and the wire feeding situation of the guide tube in real time. Utility Model Content

[0004] In order to overcome the drawbacks of existing ordinary mobile welding robots as described in the background due to structural limitations, the utility model provides a mobile welding robot body, which can monitor the amount of welding wire wrapped around the wire feeding reel and the situation of welding wire conveying by the guide tube in real time under the joint action of relevant mechanisms during application. When the welding wire on the wire feeding reel is less than the minimum threshold and there is no welding wire in the guide tube (for example, the welding wire on the wire feeding reel has been used up or broken) and is output upward to the wire feeder, it can respectively prompt on-site staff and wirelessly prompt off-site staff to handle it in time, thereby ensuring the normal and stable operation of the equipment as a whole as much as possible.

Based on the above, the utility model has a good application prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 , 2As shown in , the detection head of the photoelectric switch A2 is located in the protective shell 101 and is aligned with the outer end of the wire feeding disk 103. The left end of the detection head of the metal detection mechanism and the right end in the guide tube 102 are in the same vertical plane. The wireless transmission display circuit includes a wireless transmission circuit module A4 and relays K1 and K2, and sound and light alarms B1 and B2 connected by circuit board wiring. The negative power input end of the wireless transmission circuit module A4 is connected to the negative power input ends of the two sound and light alarms B1 and B2 and the two relays K1 and K2. The control contact end and the normally open contact end of the relay K1, the control contact end and the normally closed contact end of the relay K2 are respectively connected to the two contacts under the first transmission button S1 and the second transmission button S2 of the wireless transmission circuit module A4. The positive power input ends of the sound and light alarms B1 and B2 are respectively connected to the positive power input ends of the two relays K1 and K2. The wireless receiving circuit includes a battery G1 (model 12V / 5Ah) connected via circuit board wiring and installed in a component box, a charging socket CZ (the socket is located at), a power switch S1, a wireless receiving circuit module A5, and sound and light alarms B3 and B4. The two poles of the battery G1 and the two poles of the charging socket CZ are respectively connected via wires (when the battery G1 is out of power, an external power charger plug can be inserted into the charging socket to charge the battery G1), and are connected in series via the power switch S1 and the power input terminals 1 and 2 of the wireless receiving circuit module A5 are respectively connected via wires, and the two power output terminals 3, 2 and 4, 2 of the wireless receiving circuit module A5 and the two ends of the power input of the sound and light alarms B3 and B4 are respectively connected via wires.

[0017] Figure 1 , 2 As shown in the figure, the new type is based on the mobile welding robot body 1, which has all the welding functions of the ordinary mobile welding robot.

[0018] The mobile welding robot body 1 uses the multi-axis robot 104 with the control software system and the control working mode in its matching upper computer as a motion carrier. When working, under the action of relevant equipment, the forearm of the multi-axis robot drives the front end of the welding nozzle of the welding gun 105 close to the base material to be welded, and the wire feeder feeds the welding wire 107 continuously output by the wire feeding reel machine 103 through the guide tube 101 (the wire feeding reel 103 is wound with multiple turns of welding wire 107, and the center hole of the wire feeding reel 103 is rotated and sleeved on the rotating shaft at the rear end of the equipment, and the welding wire 107 on the wire feeding reel 103 is continuously input into the welding gun 105 through the wire feeding machine 106 and the guide tube 101) into the forearm of the multi-axis robot. In the front welding gun 105, the welding wire 107 is continuously fed by the wire feeder from the front end of the welding nozzle to the parent material to be welded, and the arc generated between the fusible welding wire and the parent material weldment is used as a heat source to melt the welding wire and the parent metal (the carbon dioxide bottle in the shell of the mobile welding robot body 1 and the like delivers protective gas to the welding area, so that the arc, the molten welding wire, the molten pool and the nearby parent metal are protected from the harmful effects of the surrounding air, so as to achieve a better welding effect), thereby making the corresponding parts of the parent metal parts welded together (the staff pulls or pushes the equipment to the relevant work station through the upper handle 108 of the mobile welding robot). The above is an existing mature industrial technology, and this application will not repeat it, nor will it provide any protection for the above technical solution.

[0019] Figure 1 , 2As shown, after the power module A1 is powered on, its 3rd and 4th pins output a DC 12V power supply to the wireless transmission display circuit, the wire feeding reel inventory detection mechanism A2, and the power input terminal of the guide tube wire feeding detection mechanism A3. After the wire feeding reel inventory detection mechanism A2 is powered on, when the amount of welding wire coiled on the wire feeding reel 103 has not reached the minimum threshold, the distance between the detection head of the photoelectric switch A2 and the outer side of the coiled welding wire is relatively close (for example, less than 5 cm), and the 3rd pin of the photoelectric switch A2 does not output a high level, the relay K1 will not be powered on, and the wireless transmission circuit module A4 will not emit the first wireless closing signal (the sound and light alarm B1 will not be powered on either); when the amount of welding wire coiled on the wire feeding reel 103 is relatively small, the distance between the detection head of the photoelectric switch A2 and the outer side of the coiled welding wire is relatively far (for example, greater than 5 cm), and the 3rd pin of the photoelectric switch A2 When the output is high level, relay K1 will be energized to close its control contact end and normally open contact end. Since the two contacts under the first transmitting button S1 of the wireless transmitting circuit module A4 are respectively connected to the control contact end and normally open contact end of relay K1, the wireless transmitting circuit module A4 will emit the first wireless closing signal (the sound and light alarm B1 will also be energized to emit sound and light signals to remind nearby staff that the welding wire wound on the wire feeding reel is about to be used up and needs to be replaced with a new one; at this moment, the remaining welding wire on the wire feeding reel can be used for about three minutes, so there is enough time for the staff to replace the wire feeding reel). When the guide tube wire feeding detection mechanism A3 is energized, when a welding wire passes through the detection head of the metal detection mechanism A3, the 3rd pin of the metal detection mechanism A3 outputs a high level, so that the relay K2 is energized to attract its control power input terminal and the normally closed contact terminal to open, and the wireless transmitting circuit module A4 will not emit the second wireless closing signal (the sound and light alarm B2 will not be energized to work); when the welding wire wound on the wire feeding reel 103 is used up and no welding wire passes through the detection head of the metal detection mechanism A3, the 3rd pin of the metal detection mechanism A3 no longer outputs a high level, so that the relay K2 will lose power and no longer attract its control power input terminal and the normally closed contact terminal to close, because the control contact terminal and the normally closed contact terminal of the relay K2 are connected to the two contacts under the second transmitting button S2 of the wireless transmitting circuit module A4, the wireless transmitting circuit module A4 will emit the second wireless closing signal (the sound and light alarm B2 will also be energized to work and send out sound and light signals to remind nearby staff that the welding wire wound on the wire feeding reel has been used up and a new wire feeding reel needs to be replaced immediately).After the power switch S1 of the wireless receiving circuit carried by the staff is turned on, the wireless receiving circuit module A5 is powered on and starts working. If the wireless transmitting circuit module A4 transmits the first or second wireless closing signal, the 3rd or 4th foot of the wireless receiving circuit module A5 will output a high level and enter the positive power input terminal of the sound and light alarm B3 or the sound and light alarm B4 respectively. The sound and light alarm B3 or the sound and light alarm B4 is powered on and sends out a sound and light signal. After seeing and hearing the sound and light signal, the staff can go to the site in time to replace the wire feeding reel, thereby ensuring the smooth progress of the welding work as much as possible.
