In this embodiment, the connecting conveying mechanism 1 moves horizontally along the operating platform 7 in a first horizontal direction, and the unloading and conveying mechanism 4 moves horizontally along the operating platform 7 in a second horizontal direction. The first and second horizontal directions are perpendicular to each other.

The feeding electric cylinder 11 pushes the loading plate 12 to move between the loading station a and the thickness measuring station b. The electrode plate 8 is placed on the loading plate 12 at the loading station a, and then the feeding electric cylinder 11 pushes the electrode plate 8 on the loading plate 12 to the thickness measuring station b for thickness measurement; a positioning groove 12a is provided on the upper end surface of the loading plate 12 corresponding to the electrode plate 8, and the positioning groove 12a is used to position the electrode plate 8 on the loading plate 12, which can effectively prevent the electrode plate 8 from detaching from the loading plate 12 due to shaking during the feeding process; the thickness measuring mechanism 2 includes two laser thickness measuring devices 21, and the two laser thickness measuring devices 21 cooperate to measure the thickness of the electrode plate 8. The multiple laser thickness measuring devices 21 cooperate with each other to synchronously measure the thickness of multiple points of the electrode plate 8, which can effectively prevent the thickness measurement of a single laser thickness measuring device 21 from being inaccurate.

[0039] like Figure 1 and Figure 5 As shown, the material unloading and handling mechanism 4 includes a transverse moving module 41 and a lifting module 42 provided at the output end of the transverse moving module 41. The output end of the lifting module 42 is provided with an adsorption device for adsorbing the electrode plate 8. The transverse moving module 41 can drive the lifting module 42 to move horizontally, and the lifting module 42 can move longitudinally relative to the transverse moving module 41, thereby driving the adsorption device to approach the electrode plate 8 for adsorption; the adsorption device includes a plurality of adsorption disks 43, and the plurality of adsorption disks 43 are fixedly connected to the output end of the material unloading and handling mechanism 4 through a fixed bracket 421, and the adsorption disk 43 is connected to a vacuum generating device, which enables the adsorption disk 43 to always have adsorption force. When the bottom of the adsorption disk 43 contacts the electrode plate 8, the vacuum adsorption capacity of the adsorption disk 43 is used to adsorb the electrode plate 8. The method of adsorbing the electrode plate 8 can effectively prevent the surface of the electrode plate 8 from being damaged during transportation. In this embodiment, the transverse moving module 41 is set as a transverse moving electric cylinder, and the lifting module 42 is set as a lifting electric cylinder.

[0040] like Figure 1 and Figure 3 As shown, the weighing mechanism 3 includes a positioning platform 31 and an electronic scale 32.

The position sensor 71 can be used to monitor the position of the support plate 6 in real time. When the cylinder 61 pushes the support plate 6 to slide to a predetermined position on the operating table 7, the cylinder 61 can be fed back in time to control the suspension of operation, thereby facilitating the unloading and handling mechanism 4 to place the plate 8 into the corresponding unloading box 5.
