^ and $ anchor the regex to the beginning and end of the string, so if what you are searching for is NOT at the beginning, or the pattern does not terminate at the end of the string, those anchors should not be used.

What you are looking for is something like this: 

$ perl -E 'my $s="ME170-5/2/8-ME172-2/2/6-ME4028"; while ($s=~m|(\d{1,
+2})/(\d{1,2})/(\d{1,2})|g){++$x;say "$x Found $1-$2-$3:" . pos($s)}'
__OUTPUT__
1 Found 5-2-8:11
2 Found 2-2-6:23

I used the "|" as regex delimiter, to avoid the "leaning toothpicks" syndrome - ie to avoid having to escape the "/".

             I hope life isn't a big joke, because I don't get it.
