[0035] The following is for reference Figures 1 to 12 This describes the conveyor line of an embodiment of the present utility model.

[0036] Reference Figures 1 to 3 , Figures 5 to 9 The conveyor line of this embodiment includes a conveying mechanism 10 and a clamping mechanism 20. The conveying mechanism 10 includes a conveying device 110, which has a conveying surface extending along a first horizontal direction. The clamping mechanism 20 includes a clamping member 20a and a lifting assembly. The clamping member 20a is at least partially disposed above the conveying surface. The lifting assembly includes a lifting driver 210, a lifting synchronizing member 20b, and a lifting member 20c. The lifting synchronizing member 20b is slidably disposed along the first horizontal direction. The lifting driver 210 is connected to the lifting synchronizing member 20b and is used to drive the lifting synchronizing member 20c. 0b slides along the first horizontal direction; the lifting member 20c is slidably disposed on the lower side of the conveying surface and the clamping member 20a in the vertical direction and extends along the first horizontal direction; the lifting member 20c is provided with a plurality of sets of oblique guide portions 250 arranged at intervals along the first horizontal direction, and the lifting synchronization member 20b is provided with a plurality of sets of guide engagement portions 240 arranged at intervals along the first horizontal direction. Each guide engagement portion 240 is slidably engaged with an oblique guide portion 250 so that when the lifting synchronization member 20b slides, it synchronously drives the lifting member 20c to move closer to or away from the clamping member 20a in the vertical direction.

[0037] In this embodiment of the present invention, the conveying device 110 conveys the plate along the first horizontal direction, and when the lifting driver 210 drives the lifting synchronizing member 20b to move along the first horizontal direction, the guide engagement portion 240 on the lifting synchronizing member 20b slides into contact with the oblique guide portion 250 on the lifting member 20c, thereby enabling the lifting member 20c to move vertically to cooperate with the clamping member 20a to clamp the plate on the conveying surface; furthermore, multiple sets of the guide engagement portion 240 and the oblique guide portion 250 are provided along the first horizontal direction, in each With the synchronous cooperation of the guide mating part 240 and the oblique guide part 250, the parts of the lifting member 20c distributed along the first horizontal direction can move synchronously along the vertical direction. Therefore, even if the plate size is relatively small and it is biased to one side of the lifting member 20c, the lifting member 20c is not easy to tilt. As a result, when the lifting member 20c abuts against the plate, the plate is subjected to uniform force along the first horizontal direction, which can effectively improve the stability of the plate clamping and is also conducive to improving the accuracy of the plate processing in subsequent processing steps.
