Assembly and testing device device assembles and tests leakproofness of elements which are subassemblies of the coffee maker, these are:
base of water tank,
sockets of water tank,
seal,
filter
All these elements are placed by operator in four jigs located on rotating table-top. Operator also receives final product. Jigs passes through three positions (it is caused by rotation of table-top). On first position head of the device picks up filter and put it on the seal. Seal is located in base of water tank. Then, head picks up socket of water tank, presses it into latch of the base and twists. On next position – there is a camera which allows operator for visual inspection of assembly on HMI panel. On last position there is a test of leakproofness of assembled component. It is done by blinding socket of the water tank, inserting tip into socket, providing pressure and its control in given time. Operator can see information about results of assembly and tests on HMI panel. Area of assembly and testing is separated from the operator with barrier. Safety is ensured by properly distanced safety light curtains integrated with safety rely units . Correct position of elements in jigs is checked by fiber optic sensors. Their undeniable advantage is the user-friendly interface and the ease of “learning”. Another advantage of assembly and testing device is the ability of installation in places with bounded spaces. The device can be optionally equipped with a vision system to check correctness of positioning latches of elements.
