Referring to fig. 1-3, a positioning jig according to an embodiment of the first aspect of the present application is used for positioning a product 300 having a runner 320 and a lens 310. Wherein, the lens 310 is fixedly connected with the runner 320, the runner 320 is provided with a first plane 321, the lens 310 is provided with a first surface 312, and the first surface 312 is parallel to the first plane 321. The positioning jig includes a base 100 and a clamping member 200. The base 100 is used to support a product 300. The clamping member 200 includes a first positioning member 210, a second positioning member 220, and a drive assembly 230, the second positioning member 220 having a second plane 221. The driving assembly 230 is used for driving the first positioning member 210 and the second positioning member 220 to clamp the flow channel 320, so that the second plane 221 is attached to the first plane 321; the driving assembly 230 is further used to drive the first positioning member 210 and the second positioning member 220 to release the flow channel 320 so as to separate the second plane 221 from the first plane 321.
