The water-cooled plate assembly machine according to claim 1, wherein: The current collecting and assembling mechanism includes a current collecting base fixedly arranged on the mounting table, a current collecting guide rail fixedly installed on the current collecting base and extending in the front-rear direction, a current collecting plate slidably connected to the current collecting guide rail, and a current collecting buffer assembly for buffering the current collecting plate; the current collecting buffer assembly includes a first current collecting limit block fixedly arranged on the current collecting base and in front of the current collecting plate, a second current collecting limit block fixedly arranged on the current collecting base and behind the current collecting plate, and a current collecting compression spring connected between the current collecting plate and the second current collecting limit block; a current collecting placement groove for placing the current collector is arranged on the current collecting plate, the front side of the current collecting placement groove is an open opening, and two opening and closing assemblies are also arranged on the front side of the current collecting plate and are respectively arranged on the left and right sides of the opening. The opening and closing assembly includes an opening and closing guide rail fixedly installed on the current collecting plate and extending vertically, a movable door slidably connected to the opening and closing guide rail for blocking or disengaging from the opening, and an opening and closing cylinder fixedly arranged on the current collecting plate for driving the movable door to move up and down.

7. The water-cooled plate assembly machine according to claim 1, characterized in that: The positioning device includes a supporting mechanism and a pressing-down mechanism; the supporting mechanism includes a plurality of supporting components arranged at intervals in the front-rear direction on the machine table. The supporting component includes a supporting table for placing the plate body, side blocking blocks fixedly arranged on one side of the front and rear of the supporting table, and pushing cylinders fixedly installed on the other side of the front and rear of the supporting table. When the pushing cylinder extends, it can push the plate body onto the side blocking block for side positioning. An end blocking block for positioning one end of the plate body is also arranged on the supporting table of the supporting component farthest from the assembling mechanism; the pressing-down mechanism includes a bracket fixedly arranged on the machine table and a plurality of pressing-down cylinders fixedly installed on the bracket and arranged at intervals in the front-rear direction. The pressing-down cylinders are located above the supporting table, and when the pressing-down cylinders extend downward, they can press the plate body tightly on the supporting table.

8. The water-cooled plate assembly machine according to claim 7, characterized in that: A supporting guide rail extending in the front-rear direction is also arranged on the machine table. Part of the supporting tables are slidably connected to the supporting guide rail in the front-rear direction through sliders. A pressing-down guide rail extending in the front-rear direction is arranged on the bracket, and part of the pressing-down cylinders are slidably connected to the pressing-down guide rail through sliders.
