Following line in your controller action is wrong

$model2->product_img='uploads/' . $file;

$file is an object not string

You may need to change that line to

$model2->product_img = 'uploads/' .$file->baseName;

or if you intend to access the file later using this column

$model2->product_img = 'uploads/' .$file->baseName . '.' . $file->extension;
