Systems for material deposition
Systems for material deposition. One such system includes a number of containers arranged relative to one another in a conical or other shape, pointing toward a common deposition point. When not actively depositing material, the containers are held at a distance from the deposition point. Another system has a rod disposed within a container and a flexible tip on the rod seals a material exit of the container when biased closed. Pressurized gas introduced into the container forces the rod away from the material exit and material from the container. In yet another system, a container includes a barrel adapter having a one-way air valve that seals the container and creates a vacuum, preventing material from leaking from the container. Upon application of a pressurized gas, the one-way valve is forced open and material is deposited from the container. The valve closes automatically in the absence of the gas.
1. A system, comprising:
a plurality of containers configured in an array to dispense material, said containers each having a material dispensing end, and the containers organized within the system so that each dispensing end of each container is oriented towards a common, single deposition point; and
a piston mounted on an arm, said arm rotatable to align said piston with mounts of each of said containers, said mounts of said containers each translatable under actuation by said piston to a deposition position at which said containers dispense material and translatable under influence of a biasing mechanism to return to an original position at which said containers do not dispense material,
wherein the array of containers is mounted on a stage translatable along an axis.
2. The system of claim 1 , wherein the plurality of containers are arranged in a cone shape, with their material dispensing ends each oriented towards the common, single deposition point.
3. The system of claim 1 , wherein the mounts of the containers are translatable under actuation by said piston along respective pairs of sliders.
4. The system of claim 1 , wherein the containers comprise syringes.
5. The system of claim 4 , wherein the syringes are arranged in a cone shape, with their material dispensing ends each oriented towards the common, single deposition point.
6. The system of claim 5 , wherein the mounts of the syringes are translatable under actuation by said piston along respective pairs of sliders.
7. The system of claim 1 , wherein said arm has a slot therein and the system further comprises a limit switch, the slot in the arm located such that when the piston is in a home position, the slot passes through the limit switch.
8. The system of claim 1 , wherein each of the containers is received in a respective one of a plurality of holders, said holders sized to accommodate containers of different sizes.
