The power member 22 includes a conveying rack 221, a driving gear 222, a driven gear 223 and a rotary driving member 224, the conveying rack 221 is disposed in the movable space 211 and is annularly disposed to form a rotary space 2211, the connecting block 232 is connected to the conveying rack 221, the pair of guide wheels 233 are disposed on two sides of the guide strip 21 and are in rolling connection with the guide strip 21, the driving gear 222 and the driven gear 223 are disposed in the rotary space 2211 and are both engaged with the conveying rack 221, and the rotary driving member 224 is connected to the driving gear 222 for driving the driving gear 222 to drive the conveying rack 221 to rotate, so that the conveying rack 221 drives the positioning fixture 10 to rotate.

Therefore, the annular processing path is adopted, the occupied space of the welding production line 100 can be reduced, the transmission of the positioning jig 10 is realized through the conveying rack 221, the driving gear 222, the driven gear 223, the rotary driving piece 224 and the guide strip 21, the structure is simple, the cost is low, and the large-scale production is facilitated.

In one embodiment, the rotational driving member 224 can be a servo motor, and the image capturing module 30 and the welding module 40 are disposed on the rotational driving member 224.

The operation of the welding line 100 is substantially as follows:

the feeding assembly 50 transfers the workpiece 200 to the jig body 11 at the upper material level 201, the jig body 11 moves to the image taking position 202 along with the conveying rack 221, the sensing member 60 starts the power-on driving member 133 after sensing the jig body 11, the power-on driving member 133 drives the positioning member 132 to drive the power-on member 131 to be inserted into the power jack 1222d, so as to switch on the conducting member 123, the light source 121 is conducted, the workpiece 200 on the jig body 11 is backlighted by the light source 121, the image taking assembly 30 is used to obtain an image of the workpiece 200 under the backlight condition, and the obtained image is transmitted to the control assembly of the welding assembly line 100, the jig body 11 drives the workpiece 200 to flow to the welding position 203 under the driving of the conveying rack 221, the control assembly controls the welding assembly 40 to complete welding of the workpiece 200 according to the analysis condition of the image of the workpiece 200, and then the welded workpiece 200 is transferred to other processes.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or substituted equivalently without departing from the spirit and scope of the technical solutions of the present invention.
