Specially made for the appliance
industry, this work cell is designed to attach metal clips to the
back of a cosmetic front panel. The heat staker simultaneously heat
stakes two posts on each of eight clips securely attaching them to
The process starts when the operator manually loads a panel into the fixture, and then loads eight clips onto the panel. The lower nest is made of urethane to ensure that there is no marking on class "A" surfaces. Next, four DE-STA-CO clamps are manually positioned to
hold the parts in place. Then the work table is moved into place,
and one DE-STA-CO clamp is closed to hold the table in position.
(Pneumatic clamps and an automated pneumatic slide table is
available as an option.) Part sensing detects that all clips are in
place, and eight heat staking heads extend (The head has a 5"
stroke.) to form the posts. Watlow temperature controllers monitor
the temperature of each staking tip, and an after staking feature
allows the staked heads to cool. This insures the stakes are solid
before the staking heads retract. The operator manually repositions
the table, and removes the completed part.
Control is provided by an Allen-Bradley Panelview 700 color touch
screen HMI interface. The device can be password protected and is
linked to the expandable A-B CompactLogix™ PLC. In addition, there
is easy access to an Opto-touch switch to begin a cycle, and to two
abort switches if the operator needs to stop the process quickly
The work table is a solid, one-inch thick extruded aluminum piece
with a Blanchard ground top giving the table superior rigidity. The
sides of the work cell have an extruded aluminum frame and clear
polycarbonate panels. The front and rear access doors are
key-lockable. (Interlock doors are an option.) A light curtain
protects the operator, while a Smog-Hog filtration system removes
fumes. The control cabinet can be locked to prevent tampering with
any of the process settings. Rugged leveling feet with swivel
casters are standard.
