Cartesian robots (Application examples)

Controlling Cartesian robot and single-axis robot with a single controller

• Multiple robots can be controlled simultaneously with one controller.
  The system can be expanded to up to two groups with eight axes.
• Multiple robots are controlled with one controller, so cooperation can be established without a PLC or IO between controllers.

Dual drive control allows long stroke axes to be used with a Cartesian combination

• A long stroke of up to approx. Y axis 2m is possible using the dual drive (2-axis synchronous) control.
• This system supports long distance transfer and heavy loading capacity specifications.
• The optimum mechanism combination and control method are proposed according to the required repeatability.

Component pick & place from the index

• Parts identified on the index by the vision device are removed and sorted by the robot.
• The vision device determines the type and position and issues the movement position to the robot.
• In addition to pre-taught positions, the robot can move to a position randomly imported from an external device.
• RS-232C, Ethernet or field buses such as CC-Link can be selected for controller communication.

Uses dual-drive to convey large and heavy workpieces.

• Dual-drive is a function that synchronizes and moves two single-axis robots of the same type.
• Even heavy items, or parts and products of different sizes can be transferred using this dual-drive function.
• This function improves acceleration and is effective for reducing cycle time.

Vehicle clutch assembly
Two types of parts are alternately assembled at a high efficiency

• The dual arm save space and reduces the cycle time.
• Dual-arm specifications can be selected as a standard.
• Either left or right can be selected individually for the Y-axis and Z-axis stroke (special order).
• The nut-rotation type X axis also supports long strokes, and maintains the maximum speed.

Conveyance with high efficiency using double arms.

• Setting 2 units on the Z axis intersecting XZ drastically cuts the total tact time and reduces the required installation space.
• Customization only possible because a highly rigid frame and guide are used.

Application of adhesive agent within a large size liquid crystal surface processing unit.

• Capable of handling large size workpieces.
• Also applicable to cutting work with a cutter, surface check with a camera, etc.

ICs are taken out of the pallet and parts are transferred to the specified place by the XYZ Cartesian robot.
Application as a part of the machine used in the process where a die is attached to the circuit board using thermocompression bonding in the manufacture of semi conductors.

• By using the RCX controller, it is possible to use the result of the operation based on variables during palletizing.

Use as a tester in the post process of manufacturing electronic parts.

• 2 units of SXYx are operated using 1 unit of RCX340 with settings for 2 robots.
• The vertical traveling accuracy of XY axes of both 2 units of SXYx is within +/ 0.05mm.

Spreading sealant to mating faces of the cases.

• Three dimensional application using 3 axes Cartesian robot.
  Cartesian robot incorporated with special purpose machine.

Used in the sheet metal processing unit.

• X1 and X2 axes are superposed for space efficiency.
• The unit layout is easy even for the doubled stroke.

Spreading adhesive agent to drums.

• Boosting the R axis strength allows 3 dimensional interpolation + R operation.
• Each axis has high rigidity and so can easily withstand harsh conditions such as on the moving arm (handles 100mm/sec).

Heavy workpiece inserted in the pallet, etc.
Heavy workpiece before processing set in the processing machine.

• Z axis moving type: The heavy workpiece is cancelled by the air balancer and moved up and down.

Tester (upper and lower probes, camera with lighting) .
Precision spot welding machine. Simultaneous assembly at upper and lower levels (caulking parts, screw tightening) .

• Simultaneous control of 2 Cartesian robots.
• Levelness of upper and lower robots assured (custom specification) .
