The technical features in the utility model can be interactively combined on the premise of no contradiction and conflict.
Referring to fig. 1, 2, 3 and 6, embodiment 1 is a novel power battery coating surface density detection and identification device, comprising:
a bracket 400;
sequentially arranging according to the detection sequence of the coated and dried pole pieces,
the line laser array thickness measuring device 100 comprises two groups of line laser array modules 120 which are adjacently arranged, wherein each group of line laser array modules 120 is respectively and slidably arranged on the upper side and the lower side of the bracket 400, acts perpendicular to the direction of the movement speed of the pole piece and is used for measuring thickness of the pole piece when the pole piece passes through;
the double-sided density detector 200 comprises two groups of ray detection units, each group of ray detection units comprises a ray source 510 arranged on the upper side of the bracket 400 and a ray source receiving sensor 520 arranged on the lower side of the bracket 400, the ray source 510 acts perpendicular to the direction of the movement speed of the pole piece, and the surface density detector is used for detecting the surface density of the pole piece;
the marking device 300 of the automatic inkjet printer is disposed at one end of the bracket 400, and is configured to print a predefined inkjet pattern according to the thickness measurement result of the line laser array thickness measurement device 100 and the surface density detection result of the double-sided density detector 200, so as to perform marking, thereby facilitating the subsequent automatic cutting process.
As a preferred embodiment of the present utility model, specifically, the upper and lower sides of the bracket 400 are respectively provided with a sliding table 110 driven by a synchronous belt, one side surface of the sliding table 110 is slidably provided with a sliding member, one half of the line lasers in each group of line laser array modules 120 are arranged at the sliding member on the upper side, and the other half of the line lasers are symmetrically arranged at the sliding member on the lower side.
Referring to fig. 4 and 5, as a preferred embodiment of the present utility model, each group of line laser array modules 120 includes 10 line lasers, and half of the line lasers are 5.
Referring to fig. 7, as a preferred embodiment of the present utility model, specifically, the radiation detecting units are slidably disposed on the other side surface of the sliding table 110, and two sets of radiation detecting units are disposed side by side and scan in the same direction.
The scanning mode of the double-sided density detector 200 adopts parallel and equidirectional motion scanning, so as to adapt to the scanning of lithium battery pole pieces of different types, the distance between two surface density scanners can be adjusted randomly according to the width of the pole pieces, the distance between the two surface density scanners needs to be adjusted to be half of the width of the pole pieces, and the stroke of the sliding table 110 is half of the width of the pole pieces. Aiming at the characteristics of complete missed detection area and low detection precision of single-sided density detection, the double-sided density detection equipment can eliminate the complete missed detection area, and the missed detection area is reduced by half because the distance of bidirectional detection walking is half of that of the original detection area, and two points are detected by each detection line in the vertical coating direction in consideration of the staggering of the two detection lines, so that the detection precision is doubled, and the complete missed detection area caused by single-sided density scanning during reversing is eliminated to a certain extent.

As a preferred embodiment of the present utility model, in particular, the bracket 400 is an integrally welded O-shaped welding bracket 400.
