Referring to fig. 3, the transfer mechanism 50 includes a second transmission member 51 and at least one lifting member 53. In this embodiment, the number of the lifter 53 is two. Two lifting members 53 are provided on the frame 10. The second transmission member 51 is disposed on the elevating member 53. In this embodiment, the two lifting members 53 are located at both ends of the second transmission member 51, but not limited thereto. The second conveyor 51 conveys the body 201 and passes through the spot welder 70. The elevating member 53 can drive the second transfer member 51 to ascend or descend. It is understood that in other embodiments, there may be one lifting member 53, with one lifting member 53 being located adjacent to the spot welder 70.
The spot welder 70 includes a welding head 71, a first electrode 73, and a second electrode 75. The second electrode 75 is provided at one end of the welding head 71 and above the transfer mechanism 50. The first electrode 73 is located below the transfer mechanism 50. The first electrode 73 and the second electrode 75 are disposed oppositely. The welding head 71 is capable of moving the second electrode 75 towards the first electrode 73.
The chassis welding device 100 also includes a blocking mechanism 80. The blocking mechanism 80 includes a positioning member 81 and two blocking plates 83. The positioning element 81 is disposed on the first electrode 73, and the positioning element 81 is electrically connected to the first electrode 73. The positioning member 81 is used to carry and position the carrier member 40. The two blocking plates 83 are oppositely disposed at two sides of the positioning member 81.
When the second transmission member 51 transmits the body 201 between the second electrode 75 and the first electrode 73, the lifting member 53 drives the second transmission member 51 to descend. The body 201 moves down between the two baffles 83 and contacts the weld 207 of the plurality of weld standards 202, 203, 204 on the carrier 40. The welding head 71 drives the second electrode 75 to move downwards until the second electrode is pressed against the body 201. When the second electrode 75 and the first electrode 73 are conducted, the high-temperature arc generated by the spot welding machine 70 during the momentary short circuit can melt each welding point 207 so as to combine the first welding standard 202, the second welding standard 203 and the third welding standard 204 with the body 201 respectively.
In the present embodiment, the number of spot welders 70 is two. Two spot welders 70 are located on the side of the transfer mechanism 50 facing away from the first conveyor 20. The number of the carriers 60 is also two. Two transfer members 60 are located on both sides of the first transfer member 20. Each transfer member 60 is capable of transferring the carrier member 40 to the first electrode 73 of a corresponding one of the spot welders 70. In this embodiment, the two spot welding machines 70 perform welding simultaneously, and the working efficiency is high. It is understood that in other embodiments, the number of spot welders 70 and transfer members 60 may be one or the other, respectively.
In operation, the plurality of carriers 40 of the chassis welding device 100 are sequentially placed on the first transfer member 20. The first transport member 20 transports the plurality of carriers 40 toward the second transport member 51. Each first feeding mechanism 30 feeds the corresponding first welding standard 202 to a set position on the carrier 40; each second feeding mechanism 35 feeds the corresponding second welding standard 203 to a set position on the carrier 40; each third feeding mechanism 36 feeds the third welding standard 204 to a set position on the carrier 40. The transfer member 60 grasps and transfers the carrier 40 carrying the first welding standard 202, the second welding standard 203, and the third welding standard 204 onto the positioning member 81. A plurality of bodies 201 are disposed at intervals on the second transmission member 51. When the second transmission member 51 transmits the body 201 to move between the second electrode 75 and the first electrode 73, the lifting member 53 drives the second transmission member 51 to descend. The body 201 is moved down into contact with each pad 207. The welding head 71 drives the second electrode 75 to move downwards until the second electrode is pressed against the body 201. At this time, the second electrode 75, the body 201, the welding standards 202, 203, 204, the supporting member 40, the positioning member 81, and the first electrode 73 are sequentially conducted. The high temperature arc generated by the spot welder 70 at the moment of momentary short circuit is able to melt the plurality of welding spots 207 to bond the first welding standard 202, the second welding standard 203, and the third welding standard 204, respectively, to the body 201. At this point, the chassis welding apparatus 100 completes the welding operation for one chassis 200.
