The both ends of ruler 2.
Measurement assembly 1 includes fixed mounting 1-1, stylus 1-2 and slide unit 1-3.Fixed mounting 1-1 is set to coating
In the rack 10 of machine, fixed with 10 phase of rack of coating machine, slide unit 1-3 is set on fixed mounting 1-1, and can along with afflux
The perpendicular direction of body moving direction (that is, width direction of collector) moves back and forth.The present embodiment is in fixed mounting 1-1
Upper setting guide rail 1-1a, slide unit 1-3 bottoms are machined with and the corresponding guide groove 1-3a for accommodating guide rail 1-1a of guide rail 1-1a, slide unit
1-3 is equipped with by guide groove 1-3a and guide rail 1-1a's on fixed mounting 1-1, so as to pacify along guide rail 1-1a fixed
Fill laterally (width direction of collector) movement on seat 1-1.It is of course also possible to the installation site of guide rail and guide groove is exchanged, it will
Guide rail is set on slide unit, and guide groove is correspondingly arranged on fixed mounting, can equally be realized and be moved slide unit in guide groove
Ground is set to the purpose on fixed mounting.Location nut (not shown) can be set on slide unit 1-3, when slide unit 1-3 pacifies fixed
It fills after adjusting good position on seat 1-1, can be fixed in by location nut on fixed mounting 1-1.It is located at scale two respectively
Fixed mounting in the measurement assembly at end can be separated from each other it is independent or integrated.When using integral structure
When, two slide units are all mounted on same fixed mounting, respectively positioned at the both ends of fixed mounting.Scale can also be set
In on fixed mounting.
Stylus 1-2 is set on slide unit 1-3, is fixed with slide unit 1-3 phases, and when slide unit 1-3 is moved, stylus 1-2 is also with slide unit
1-3 is moved, and the moving range of stylus 1-2 is in the scale zone of scale 2.It is directed toward the afflux on coating machine in one end of stylus 1-2
Body 20, the other end are directed toward scale 2, and the stylus 1-2 of the present embodiment is perpendicularly oriented to the surface of collector 20.For ease of description, will
One end that stylus 1-2 is directed toward collector is defined as head, and the other end is defined as tail portion.When slide unit 1-3 is moved, stylus 1-2 with
Slide unit 1-3 is moved in the meter full scale of scale 2.In order to accurately be measured to the coating size on collector, stylus 1-2
Head can slightly be in contact with the surface of collector.In order to protect the not tested needle scratch of collection liquid surface or puncture, it is preferred that
The head of stylus 1-2 is arc, and the arc-shaped head of stylus 1-2 is slightly contacted with collection liquid surface rather than tip and afflux body surface
Face contacts, it is ensured that collection liquid surface is not damaged during measurement.A diameter of 0.5mm of stylus 1-2 used by the present embodiment.
Since scale 2 and fixed mounting 1-1 are relatively fixed, when slide unit 1-3 drives stylus 1-2 movements, stylus
1-2 can be directed toward scale different on scale 2.Scale 2 can be located at the lower section of stylus 1-2 tail portions, for example, stylus 1-2 tail portions are hanging,
Scale 2 is located at the lower section of the hanging tail portions of stylus 1-2 or the tail portion of stylus 1-2 and is fixed on slide unit 1-3, and scale 2 is directly set
The lower section of the interlude of slide unit 1-3 is exposed in stylus 1-2, the position of scale can mutually be strained according to the installation position of stylus
Change.

Mirror 3, magnifying glass 3 can be amplified the size scale on the scale 2 pointed by stylus 1-2 tail portions, and the multiple of magnifying glass can be
20 times.At the same time it can also scale zone different on scale 2 is identified using different colors, such as coating size permits
Perhaps error band (Fig. 2 bends fill part) is identified with green, coating dimension limit error band (grid filling part in Fig. 2
Point) identified with red, when stylus 1-2 is located at corresponding region, testing staff is facilitated to confirm rapidly and adjusts size in time.
With reference to Fig. 1 and Fig. 2, the use process of the utility model is described in detail：
Fixed mounting 1-1 is mounted in the rack 10 of coating machine, slide unit 1-3 is set on fixed mounting 1-1,
The distance between slide unit 1-3 and the coating width of collector are adapted, and the length of scale 2 is mutually fitted with the coating width of collector
It should；
The position of slide unit 1-3 in the wherein a set of measurement assembly 1 of adjustment, makes the head of stylus 1-2 on slide unit 1-3 be directed at afflux
The one side edge of body spreading mass dispensing area, at this time projection of the stylus 1-2 heads on collection liquid surface and collector spreading mass
The coincident of dispensing area fixes slide unit 1-3, makes its immovable, scale 2 is fixed, it is made to be relatively fixed mounting base
1-1 is immovable, and fixed stylus 1-2 is located on scale 2 in coating size allowable error region；
The position of slide unit 1-3 in mobile another set of measurement assembly 1, makes the head of stylus 1-2 on slide unit 1-3 be directed at collector
The other edge of spreading mass dispensing area, observing on the slide unit 1-3 stylus 1-2 and whether being located at coating size on scale 2 allows to miss
In poor region, if located in size qualification is then coated in coating size allowable error region, if having exceeded coating dimension limit
Error band then needs to adjust coating size in time.
Above example is only to illustrate the technical solution of the utility model rather than its limitations, although with reference to above-mentioned implementation
The utility model is described in detail in example, it should be understood by a person of ordinary skill in the art that still can be to this reality
It is modified or replaced equivalently with novel specific embodiment, and is repaiied without departing from any of the spirit and scope of the utility model
