Glossary
Steel ball snap
ring
The steel ring on the tool side,it fits to the locking steel ball during
locking.
Cam
Circular cam attached to the piston that forces the locking balls outward
during the locking process.
Electrical
Module
a wide variety of utility modules that pass electrical power or electrical
signals through Master plate to Tool plate and then to the end-effector.
End-Effector
A tool installed on a robot to perform a certain function.
adapter flange
Optional components for the installation between the transition of robot
tool changer to the robot or tools.
Locking ball
Hardened steel ball for locking mechanism with air pressure lost
protection function.The locking cam extrudes the steel ball and clamps it
with the steel ball snap ring on the tool side,Realize the master plate
locking tool plate.
Locking
mechanism
It is used to pull the master plate locking tool plate, which can ensure
reliable locking even in case of air loss until the mechanism is unlocked
normally. The locking mechanism includes locking steel ball, cam, ball
bearing cover, ball race, etc.
Lock Port
Pneumatic port on the Master plate to which air is supplied to Lock the
Master plate to the Tool plate.
Master plate
The half ofthe Tool Changer that is mounted to a robot. The Master plate
contains the locking mechanism.
Moment
The applied force multiplied by the distance it is from a point

Air module
pass air power through the Master plate to the Tool plate and to the end
effector.
Sensor plate
seals the pneumatic chamber and provides mounting points for the
Lock/Unlock switches.
Tool Plate
The half of the Tool Changer to which various tools or end-effector are
mounted.
Tool stand

The master plate unlocks the port of the air supply circuit to drive the
master plate to be separated from the tool plate.
Arc
Prevention
makes it possible to couple/uncouple without switching off electrical
module power. Arcing can damage and shorten the life of the electrical
power contacts. Arc Prevention extends the life ofall electrical power
contacts by eliminating arcing caused by inductive loads and high inrush
current during coupling/uncoupling.
Coupling
Lock
Discrete
Refers specifically to modules that pass discrete signals and/or power
from Master to Tool. The number of discrete pass-through signals is
limited by either the number of pins on the connector or the number of
pins at the pin block interface between Master and Tool. Some Discrete
modules also provide the user the ability to control the Tool Changer by
providing "Latch" and "Unlatch" signals to an integrated valve that locks
and unlocks the Tool Changer. The Tool Changer Locked, Unlocked,
Ready-to-Lock, and TSI switch signals can also be provided to the user,
these discrete modules are referred to as Discrete Control/Signal Module.
Ethernet
Switch
An Ethernet network component connecting multiple communication
partners with each other
Fieldbus
A generic term referring to any one of a number of industrial computer
networking standards. Examples include: CAN, Modbus, and PROFINET

An individual or set of push button switches on the control/signal Tool
module that provides a unique identification number for each tool when
using multiple tools. The tool-ID also provides the tool not present
indication.
Tool Present
A hard-connect input (sourced from the Tool) indicating the Master and
Tool are electrically connected to each other.
Trip Dog
A physical device used to trip a mechanical switch, use in the Tool Stand
Interlock circuit.
Uncoupling
See unlock
Unlatch
The input signal supplied to the ATI Master module to uncouple the Tool
Changer.
Unlock
The physical action ofthe uncoupling the Master and Tool Plates.
Unlocked
A proximity sensor output signal indicating that the coupling mechanism
is in the Unlocked position.
Unlock sensor
A proximity sensor that detects the position of the pneumatically-actuated
piston when it is in the unlocked position.

expected during operation. Please refer to the product specifications in each
models of this manual.Pls pay attention to dynamic load which caused by
acceleration and deceleration of robot’s movement. In the case of high acceleration
or deceleration, these forces may be much bigger than the static force.
It is the User's responsibility to ensure that in locking status and during
locking process ,there has no foreign matters between master plate and tool plate,
otherwise will cause serious injury.
Danger: the gap between the master plate and the tool plate is a pinch
point. All personnel shall be prevented from placing any part of their
body or clothing in the gap, especially during the operation of the
locking mechanism.
User is responsible to learn the functions of robot tool changer,and operate
appropriate fasteners and software to safely operate the tool changer. It shall be
controlled to avoid endangering personnel or equipment during locking or
unlocking.
All pneumatic fittings and piping must be able to withstand repeated
movements of the application without failure.The wiring of electrical and
pneumatic pipelines must minimize the possibility of sprains, kinks, cracks, etc.
Failure of key electrical or pneumatic pipelines to work properly may cause injury
to personnel and equipment.
Disconnect all power, pneumatic and fluid circuits during maintenance.
Warning: Pls remove all temporary protective materials (cover, plug,
tape, etc.) from the locking surface of the tool changers and modules
before operation. Otherwise, the tool changer, module and end-arm
tools might be damaged and cause personal injury.

1.3 Safety notes:
Warning: do not maintain or repair the tool changer or module ，
Unless the tool is safely supported or placed on the tool stand ， All
energized circuits (such as electrical, air, water, etc.) have been closed,
the high-voltage connection has been cleaned, and the power supply has been
discharged from the circuit in accordance with the customer's safe operation
procedures and policies.Personal injury or equipment damage may result if not
placed in the tool holder and the circuit is energized. Place the tool on the tool
holder, close and discharge all energized circuits, release all pressurized
connections, and confirm that all circuits are powered off before maintaining or
repairing the tool changer or module.
Warning: during operation, the area between the master plate and the
tool plate must be kept clean. If the area is not kept clean, the tool
changer, module or end-arm tool will be damaged and personal injury
may be caused.
Warning: the tool changer is only used for the intended application

2. Product overview
The LT robot tool changer enhances the universality of the robot by using a
variety of tools (such as fixtures, vacuum suction cups, pneumatic and electric
motors, welding guns, etc.). The tool changer includes a master plate installed on
the robot arm and a tool plate installed on the customer's tool. When the robot picks
up the tool, the pneumatically driven locking mechanism connects the two plates.
The fault self-locking mechanism of the patent adopts multi conical cam with ball
locking technology, Ensure during operation, If the air pressure less than 60psi (4.1
