Description
Technical field
The present invention relates to a kind of photoelectric encoder manufacturing technology, more particularly to a kind of photoelectric encoder slit sheet that is used for be aligned
The calibrating plate of operation.
Background technology
Photoelectric encoder is a kind of very common photoelectric device, and its typical structure is as shown in figure 1, on it can be seen that
Circuit board and lower circuit board are separately positioned on the both sides up and down of coding disk, and upper circuit board and lower circuit board are fixed on by connecting pole
On base, coding disk is fixed on power transmission shaft（Passing through of being matched with power transmission shaft is provided with upper circuit board and lower circuit board
Hole）, when drive axis, coding disk will relatively rotate under the drive of power transmission shaft with upper circuit board and lower circuit board；On
Multiple luminous tubes are provided with the downside of circuit board, multiple photosensitive tubes are provided with the upper side of lower circuit board, it is multiple luminous
Pipe and multiple photosensitive tubes correspond, and the top of photosensitive tube is covered with slit sheet；Coding disk is typically made using metal or glass,
During using metal, by set on coding disk it is multiple engrave hole to form code channel, during using glass, by being set on coding disk
Multiple light tight regions form code channel；The a plurality of coding seam matched with code channel is provided with slit sheet, when coding seam and is lighted
When light path between pipe is unobstructed, the light that luminous tube is sent just can pass through coding seam to be radiated on photosensitive tube, become through photosensitive tube
Binary " 1 " signal is obtained after changing, when the light path between slit sheet and luminous tube is stopped, corresponding photosensitive tube is with regard to defeated
Go out binary " 0 " signal, a plurality of coding seam and multiple photosensitive tubes are formed a multidigit binary coding device, work as coding
Corresponding coding, which sews, when disk turns to different angle positions, on slit sheet blocks, we can just obtain corresponding to multidigit two
Scale coding, according to multidigit binary coding, we are with regard to that can precisely measure out current angle position.
When stating photoelectric encoder before assembly, following difficult point be present：To ensure measurement precision, the extended line for encoding seam must
The axle center of power transmission shaft must be accurately directed at, for 10 conventional encoders, the deviation in coding seam extended line and axle center have to be lower than
15 microns, in addition, for avoid from adjacent encoder seam through optical signal interfere, slit sheet must be close to coding disk, its
Gap is typically no more than 50 microns, in addition, to ensure that code channel can correctly shelter from phase in corresponding angle position
The coding seam answered, also accurately to control the relative position of slit sheet and coding disk；Due to being gone back on lower circuit board around slit sheet
Be provided with other components, in order to avoid slit sheet and other components interfere, the size of slit sheet it is general just with it is more
The size adaptation of individual luminous tube institute overlay area, therefore slit sheet can not be made as to circle ring be enclosed on power transmission shaft to pass through
Endoporus proper alignment determines the position of slit sheet（Further, since in the course of work, slit sheet can relatively rotate with power transmission shaft, be
Avoid slit sheet from being influenceed by power transmission shaft, be also not suitable for adjusting the position of slit sheet using endoporus proper alignment）；Prior art is in group
During dress, typically first slit sheet is temporarily fixed on erecting bed, is then again installed in place coding disk, then again by fine setting side
Formula carries out accurate adjustment to the relative position of slit sheet and coding disk, is finally again permanently fixed slit sheet, it can be seen from figure 1 that narrow
Patch is located at below coding disk, and after loading onto coding disk, because the code channel being encoded above slit sheet on disk blocks, observation difficulty is very
Greatly, and because the gap between slit sheet and coding disk is smaller, the difficulty of slit sheet position adjustments operation is also very big, causes to grasp
It is low to make efficiency, and is also easy to scratch coding disk.
The content of the invention
The problem of in background technology, the present invention propose a kind of school for photoelectric encoder slit sheet alignment function
Quasi- disk, the photoelectric encoder include slit sheet, power transmission shaft and coding disk；A plurality of code channel is provided with the coding disk；It is described
The a plurality of notch matched with the code channel is provided with slit sheet, the region that a plurality of notch is covered is designated as coding seam；
Its innovation is：The calibrating plate is disk structure body, and the circle matched with power transmission shaft is provided with calibrating plate

It is circumferentially distributed along calibrating plate to save area three.
The present invention principle be：During assembling, first power transmission shaft, connecting pole and lower circuit board are installed in place（Photosensitive tube is pre-
First it has been integrated on lower circuit board）, then calibrating plate is socketed on power transmission shaft by circular connecting hole and (set in the middle part of power transmission shaft
Have the spacing preiection for installing coding disk, calibrating plate is just installed on this spacing preiection), after calibrating plate installation is steady, rotation
Calibrating plate, peep hole is rotated to the position of the top of slit sheet installation position, then straight flange described in accurate adjustment, be located at straight flange
In light path between luminous tube and photosensitive tube, after the position adjustments of straight flange are good, by positioning hole and locating notch, in erecting bed
Make upper mark on upper surface（Erecting bed is arranged on lower circuit board, and erecting bed is used to install slit sheet）, then rotational alignment disk,
Installation gap is rotated to the top of slit sheet installation position, then slit sheet is placed on erecting bed, then adjust slit sheet
Position, make first through hole on slit sheet and the second through hole respectively with two at mark（Pass through positioning hole and locating notch institute
