Laravel query returns column not found - php

Question

I want to get list of products if they are not exist in my collection. But it returns column not found.
Error
SQLSTATE[42S22]: Column not found: 1054 Unknown column '1' in 'on clause' (SQL: select * from `products` inner join `collection_products` on `collection_products`.`collection_id` = `1` and `collection_products`.`product_id` != products.id where `products`.`status` = active)
Code
public function edit($id)
{
$collection = Collection::findOrFail($id);
$products = DB::table('products')
->where('products.status', 'active')
->join('collection_products', function ($join) use($id) {
$join->on('collection_products.collection_id', '=', $id)
->where('collection_products.product_id', '!=', 'products.id');
})
->get();
return view('admin.collections.edit', compact('collection', 'products'));
}
Screenshot
collection_products Table
Logic
By query above I should get all products with status of active, except products with id's of 3, 4, 20 because they are already signed to this collection.
Any idea?

Try this query or use it as reference.
$product = DB::table('products')
->join('collection_products','collection_products.product_id','!=','products.id')
->where('products.status', 'active')
->where('collection_products.product_id', '!=', 'products.id')
->where('collection_products.collection_id', '=', $id)
->get();
