IEC 62552 Automatic Refrigerator Drawer Push And Pull Testing
Machine
Standard:
Drawer push-pull testing machine is designed and manufactured
according to IEC62552: 2015 and customized requirements.
This equipment adopts the mature technology of PLC intelligent
control, is equipped with a position-adjustable action actuator,
and a suction cup structure to adsorb the surface of the
refrigerator. At the same time, it is equipped with a colour LCD
touch screen as standard, which can pre-set the number of tests,
the time of opening and closing the drawer, and the test frequency,
so as to truly simulate the manual opening and closing of the
refrigerator. Close the refrigerator drawer to achieve intelligent
control, and one machine can be used for multiple purposes.
It is used for the durability test of the drawer of the vertical
freezer, and also used to cooperate with the energy efficiency
performance test of the refrigerator to open and close the door. It
is a dedicated fully automated testing equipment, suitable for
testing and certification agencies, factory laboratories and other
testing departments.

Test Equipment Unit Introduction
The design of the system is based on the principle of
modularization, and is designed and manufactured in strict
accordance with the requirements of the standard, and at the same
time, standardized design and components are used as much as
possible. Ensure that the system has optimal performance and
technical support.
The use of cylinder drive ensures the high reliability and
extremely long service life of the entire system.
The whole system has clear functions, compact structure, beautiful
appearance and reasonable layout, which is convenient for
maintenance and daily maintenance.
The design and manufacture of the equipment meet the general
technical requirements of the customer for the equipment.
Intelligent electronic control system
- This unit mainly includes control cabinet, control circuit,
operation panel and core control components. The electrical control
components of the system are centrally installed in an electrical
control cabinet, and the cabinet is equipped with exhaust
facilities
- The system adopts Mitsubishi PLC intelligent control, 7-inch color
touch screen operation.
- The system is equipped with an angle sensor, communicates with PLC,
and monitors the inclination angle of the door body in real time
- The system software program is prepared by our company, and the
test rate, number of tests, and test angle can be preset by touch,
which fully meets the requirements of the relevant provisions of
the standard.
Purpose, principle and structure of apparatusEquipment principle: Drive the manipulator through the air
cylinder, pull the soft rope to drive the drawer closed by the
suction cup to the maximum limit, then the air cylinder pushes the
pressing wheel to close the drawer, and each pull and push of the
drawer is a cycle.
Test machine structure: as shown in the figure below, the overall
frame structure is adopted, and the sample is placed on the bottom
plate of the equipment, so that the relative motion is internal
stress and the shaking of the equipment is reduced. A column-type
structure is installed on the bottom plate, and the column contains
3 sets of drawer push-pull mechanisms, as shown in Figure 1 below,
which can meet the test up to 3 drawers.
