"尽量收集进来" can be translated into English as "try to gather as much as possible" or "make every effort to collect everything (you can)".
The first option, "try to gather as much as possible," emphasizes the effort to collect a large quantity or the fullest extent possible.
The second option, "make every effort to collect everything (you can)," places more emphasis on the exhaustive nature of the collection effort, implying that one should strive to include every possible item or piece of information.
Both translations are appropriate depending on the context and the level of emphasis you wish to convey.
