As shown in fig. 5, in which the same or corresponding components as in the first embodiment are denoted by the same reference numerals as in the first embodiment, only the points of difference from the first embodiment will be described below for the sake of convenience. The second embodiment is different from the first embodiment in that:

as shown in fig. 5, the fourth transmission assembly 62 includes a connecting rod 621, one end of which is fixedly connected to the connecting frame 434 and is provided with a multi-section structure, a second welding head set 622 mounted on the connecting rod 621, and a plurality of second hoop members 623 fixedly disposed below the connecting rod 621, wherein the second hoop members 623 include a telescopic unit e624 vertically disposed downwards and a second semicircular hoop 625 disposed at a lower end of the telescopic unit e 624.

In this embodiment, through setting up the first welding head group 42 of fourth transmission assembly 62 cooperation for first welding head group 42 drives second welding head group 622 through first welding head group in step when carrying out weldment work and accomplishes the weldment work to wiring board 30, and both work are in step when saving extra power take off, and on the other hand utilizes second hoop piece 623 to accomplish fixing a position the wiring end 40 of coil, and then makes wiring board 30 weldment work time, and the welding is accurate and difficult emergence skew.

The working process is as follows:

firstly, starting the first transmission assembly 12, wherein the coil 10 randomly falls between the screw 121 and the optical axis 122, and the rotating screw 121 cooperates with the optical axis 122 to drive the coil 10 to automatically lie down and transmit towards the height limiting mechanism 2;

then, the second driving assembly 31 is started, the partition 324 of the spacing assembly 32 is lifted between the corresponding first driving assemblies 12 under the guidance of the first guide assembly 33, and meanwhile, when the top plate 342 is conveyed to the position right below the disk 341, the top plate 342 contacts and jacks up the disk 341, and the time for the coil 10 to pass through smoothly is ensured;

then, the coil 10 and the partition plate 324 transmit backwards together, the partition plate 324 is static, the coil 10 is limited by the partition plate 324 under the action of the first transmission assembly and cannot transmit backwards continuously, only circumferential rotation can be performed, in the rotating process, the terminal 40 rotates into the partition plate 324 and rotates continuously, the terminal 40 rotates to the bayonet of the arc-shaped groove 320, so that the terminal 40 is limited to be located at the lowest point of the coil 10, and the deviation rectification work is completed;

then, after the coil 10 is transmitted to the welding platform 41, the partition 324 is driven by the second transmission assembly to separate from the coil until the coil is transmitted to the distance sensor, the distance sensor detects the partition 324 and sends a signal to the linear cylinder 432 to start the linear cylinder 432 to move downwards, the linear cylinder 432 is started, the first one-way rack 43a vertically moves downwards to drive the first driving gear 51a to rotate, the first driving gear 51a drives the sprocket chain transmission unit b511 to transmit, and the sprocket chain transmission unit b511 drives the static contact positioning tool 512 to transmit to the position under the first welding head group 42 to complete the welding work;

then, when the first welding head group 42 is reset, the second one-way rack 43b drives the second driving gear 51b to rotate, the second driving gear 51b drives the chain wheel and chain transmission unit b511 to transmit, the chain wheel and chain transmission unit b511 drives the static contact positioning tool 512 to transmit and leave the position under the first welding head group 42, and meanwhile, the next static contact positioning tool 512 transmits and waits for the position under the first welding head group 42 to which the next static contact positioning tool 512 is mounted;

meanwhile, when the semi-finished product moves to the lifting portion b52b through the control rod b522, the static contact positioning tool 512 is guided by the second guide assembly 52 to be transmitted to the second welding mechanism 6, at this time, the first welding head group 42 descends, and simultaneously, the fourth transmission assembly 62 drives the second welding head group 622 to complete the welding work on the wiring board 30, and finally, the finished product is manually taken down and placed in the collection bin for collection.

It should be noted that when the finished product rotates to the position below the chain wheel and chain transmission unit b511, the finished product will automatically fall into the collection bin, and a part of the finished product which is not easy to fall off can be picked up manually; or can be manually taken directly at the output end.
