How to remove punctuation in references?

[Meng-bin]

I want to remove the "." after the volume and year, and the "," after the year and page number. I am not familiar with this area yet, so if anyone can help me solve this problem, I would be very grateful. Below is my latex code and examples.

\usepackage[style=numeric,sorting=none,terseinits=true]{biblatex}

\addbibresource{cas-refs.bib}

\DeclareFieldFormat[article]{number}{}
\DeclareFieldFormat[article]{doi}{}

\DeclareFieldFormat[article]{volume}{#1}
\DeclareFieldFormat[article]{year}{#1}
\DeclareFieldFormat[article]{pages}{#1}

\DeclareFieldFormat[article]{title}{#1}

\DeclareDelimFormat{volumyeardelim}{\space}
\DeclareDelimFormat[article]{yeardelim}{\space}

\DeclareCiteCommand{\cite}
{\usebibmacro{prenote}}
{\textbf{[\thefield{volume} (\thefield{year}) \thefield{pages}]}}
{\usebibmacro{postnote}}
{\usebibmacro{finentry}}
