It measures, is arranged since optical fiber detecting probe 52 is mounted on knife rest head 3101 to be spaced with cutting blade 33, it can be more accurate
Really ensure that detected tape-stripping length disclosure satisfy that the demand for pasting processing.Adhesive tape is extracted walking, and fiber laser arrays are visited
The optical signal detected is transferred to fiber amplifier 51, fiber amplifier by first 52 detection length of tape, optical fiber detecting probe 52
51 will be changed into electric signal after light optical signal amplification and pass to assembly controller, wait that extracted out length of tape meets to paste and want
When asking, assembly controller control active drive motor 21 stops and controls the operation for carrying out dicing tape.Work as optical fiber detector
When detecting adhesive tape by walking without adhesive tape in slot 311, optical fiber detector transmits the letter that adhesive tape is finished to controller
It ceases, controller then controls the automatic adhesive tape application and is sticked for application work is stopped at this time, and staff is waited to replace new adhesive tape
It is sticked at and then by controller control automatic adhesive tape application for application work is continued.
As shown in Figure 3 and Figure 7, during adhesive tape is extracted out and walked, in order to make adhesive tape be extracted the process of walking more
Smooth, therefore, adhesive tape cutting structure 30 further includes that multiple adhesive tapes dredge idler wheel 35.Multiple adhesive tapes are dredged idler wheel 35 and are arranged in adhesive tape
By in slot 311, and multiple adhesive tapes dredge idler wheel 35 and are in turn spaced setting.Adhesive tape is when across adhesive tape by slot 311, by more
A adhesive tape dredges the carrying of idler wheel 35, thus adhesive tape is in being extracted walking process, and adhesive tape, which dredges idler wheel 35 and carries out rotation, to be dredged, and is made
Obtaining adhesive tape can walk along identical conveying track always, avoid adhesive tape that position offset occurs.
It is correct in order to ensure to go to during carrying out cutting cut-out to adhesive tape as shown in Fig. 4, Fig. 7 to Figure 11
Property, and ensure that the cutting edge of cutting blade 33 is correct always consistent relative to the cutting position of double-sided adhesive band, and therefore, peace
It fills and is additionally provided with sliding cutting groove 314 on the knife rest head 3101 of knife rest 31, the cutting edge of cutting blade 33 is located at sliding cutting groove
In 314, and slides cutting groove 314 and pass through slot 311 across adhesive tape.Further, sliding cutting groove 314 is disposed therein a glue
Band dredges the underface of idler wheel 35, and the cutting edge of circular knife and adhesive tape dredge the spacing distance between idler wheel 35 and be equal to glue
Thickness with carrying belt coordinates the flexibility characteristics of adhesive tape itself, to protect in this way, during cutting double-sided adhesive band
It has demonstrate,proved and has only been turned off double-sided adhesive band without causing any cutting to damage adhesive tape carrying belt.
As shown in Figure 5 and Figure 6, the adhesive tape gluing header structure 40 of the present embodiment further includes mounting blocks 43, and mounting blocks 43 connect
