The guide rail 1 and the longitudinal guide rail 1 are connected by an arc guide rail 1, the driving end of the transport motor 1 is located at the center of the two sets of arc guide rails 1, and is connected to a set of drive rods 1, the end of the drive rods 1 is provided with a set of long guide grooves 1, and a set of guide wheels 1 is installed on the longitudinal connecting rods 1 through a guide block 1. The guide wheels 1 are limited in the long guide grooves 1 and reciprocate along the transport guide rail 1 under the drive of the drive rod 1, so as to drive a set of clamping units 1 to reciprocate between the tail end of the feeding conveyor line and the rotary positioning mechanism, and another set of clamping units 1 synchronously reciprocate between the rotary positioning mechanism and the turntable.

6. The detection production line of a temperature protector according to claim 1, characterized in that: The unloading and handling mechanism includes a clamping claw unit 2 driven by a handling drive mechanism 2 to perform reciprocating motion; the handling drive mechanism 2 includes a base frame 2, a transverse slider 2 mounted on the base frame 2 along the transverse sliding connection, a longitudinal connecting rod 2 mounted on the transverse slider 2 along the longitudinal sliding connection, and a clamping claw bracket 2 fixed at the bottom end of the longitudinal connecting rod 2. The clamping claw unit 2 is provided with three groups and is arranged side by side in the transverse direction and mounted at both ends of the clamping claw bracket 2. A handling motor 2 and a handling guide rail 2 are also installed on the base frame 2. The handling guide rail 2 includes a transverse guide rail 2 and a longitudinal guide rail 2 located at both ends of the transverse guide rail 2, and the transverse guide rail 2 and the longitudinal guide rail 2 are connected by an arc guide rail 2. The driving end of the handling motor 2 is located at the center of the two groups of arc guide rails 2, and is connected to a group of driving rods 2, and the end of the driving rod 2 is opened. There is a set of two long strip guide grooves, and a set of two guide wheels are installed on the longitudinal connecting rods through two guide blocks. The two guide wheels are limited in the two long strip guide grooves, and are driven by the driving rods to make reciprocating motion along the transport guide rails to drive the first set of two clamping units to reciprocate between the transfer platform and the transition platform, the second set of two clamping units to reciprocate synchronously between the transition platform and the transition platform, and the third set of two clamping units to reciprocate synchronously between the transition platform and the unloading conveyor line. A detection camera five is provided between the transfer platform and the transition platform to take photos and detect the bottom of the product passing above. A detection camera six is ​​provided between the transition platform and the transition platform to take photos and detect the bottom of the product passing above. An NG channel is also provided between the ferry platform and the unloading conveyor line to clamp the unqualified material received by the clamping unit two.
