Two groups of measuring mechanisms are equiped with plate, two groups of measuring mechanisms are symmetrically arranged at the both sides of through hole frame, and measuring mechanism includes driving machine
Structure, image acquiring device and grating scale, figure acquisition device are connected to be driven by the drive mechanism with drive mechanism and moved, and image obtains
Device is taken to point to the image that through hole frame is used to obtain the battery pole piece passed through from through hole frame, grating scale is located at drive mechanism one
Side.
The drive mechanism includes motor, screw mandrel and guide rail, and screw mandrel one end and motor connection, the screw mandrel other end pass through installation
Frame is arranged on seat board, and the screw mandrel is installed by bearing and mounting bracket, and grating scale is arranged on screw mandrel side, cunning is equiped with screw mandrel
Motion block, the both sides of the sliding shoe are actively installed on guide rail and grating scale respectively, and image acquiring device is arranged on sliding shoe.
Described image acquisition device is made up of camera and light source.
The motor is stepper motor.
The through hole frame is rectangular, oval frame or circle.
Described guide rail and grating scale one end is connected with mounting bracket.
The guide rail and grating scale are separately positioned on the both sides of screw mandrel.
The guide rail is arranged on the region between screw mandrel and through hole frame, or grating scale is arranged between screw mandrel and through hole frame
Region.
The utility model is measured using two groups of measuring mechanisms to battery pole piece, and easily battery pole piece can be coated with
A/B faces misplace and the measurement of width, and manufacturing cost is low, and measurement is accurate, is not only adapted to the measurement of wall scroll coating, can also use
Measured in a plurality of zebra coating.
Brief description of the drawings
Accompanying drawing 1 is the utility model dimensional structure diagram；
Accompanying drawing 2 is the schematic side view that the utility model measures battery pole piece.
Embodiment
For the ease of the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model discloses a kind of battery pole piece measurement apparatus, including seat board 1, the seat board 1
The through hole frame 2 passed through for battery pole piece 10 is provided with, is equiped with two groups of measuring mechanisms on seat board 1, two groups of measuring mechanisms are symmetrical
The both sides of through hole frame 2 are located at, measuring mechanism includes drive mechanism, image acquiring device and grating scale 6, and figure acquisition device is with driving
The connection of motivation structure is driven by the drive mechanism moves, and image acquiring device points to through hole frame and is used to obtain what is passed through from through hole frame
The image of battery pole piece, grating scale are located at drive mechanism side.Drive mechanism drives image acquiring device to move back and forth, so as to right
The battery pole piece passed through from through hole frame measures, while often measures the position that a point just records corresponding grating scale,
Convenient verification and calculating.
The drive mechanism includes motor 9, screw mandrel 5 and guide rail 4, and the one end of screw mandrel 5 is connected with motor 9, and the other end of screw mandrel 5 leads to
Mounting bracket 3 is crossed on seat board 1, the screw mandrel 5 is installed by bearing and mounting bracket 3, and grating scale 6 is arranged on the side of screw mandrel 5, silk
Sliding shoe 7 is equiped with bar 5, the both sides of the sliding shoe 7 are actively installed on guide rail 4 and grating scale 6 respectively, image acquiring device peace
On sliding shoe.The motor is preferably stepper motor.
Certainly, drive mechanism can also be other structure types, the mode such as transmitted by motor driven timing belt, will scheme
As acquisition device is arranged on timing belt, so as to also achieve moving back and forth for motor driven image acquiring device, shooting is realized.
Described image acquisition device is made up of camera 8 and light source.Light source is annular light source.Camera is the face of 2,000,000 pixels
