The automated test equipment comprises a mechanical static load test station, an impact load test station, a door lock switch performance test station, a sign or coating adhesion test station and a general inspection or electrical performance test station. The specific structure of each station is described in detail below:
the mechanical static load test station is divided into an external static load test and an internal static load test, wherein the external static load test comprises three tests of measuring box shell rigidity, shell tolerance and shell torsion resistance; the internal static load test comprises two tests of a threaded link metal insert and a hinged metering box door. The hardware component comprises a lifting rotating mechanism, an air cylinder and a force application element. The positioning technology for the metal inserts in the metering box in a threaded connection mode adopts laser sensors to walk and position up and down on two sides of the metering box. In this embodiment, the mechanical static load test station includes a housing stiffness test, a tolerance unit, a housing torsion test unit, a metal insert test unit for a nonmetallic medium-screw link, and a door test unit for an articulated metering box. In the shell rigidity test and tolerance unit, the shell rigidity test method is that SL5 is selected, the test force is 500N, and the duration is 1min; the housing withstand unit successively applies a load of 60N to each side wall of the housing for 5min. The force of the unit is provided by a belt guiding air cylinder, and the force is judged by a pressure sensor. The overall dimensions of the workpiece dictate that the unit requires X, Y, Z degrees of freedom. When the rigidity test of the shell is performed, the corresponding output air cylinder acts, and other air cylinders do not act; when the shell endurance test is performed, the corresponding output air cylinder acts, and other air cylinders do not act. In the shell torsion test unit, the torsion unit of the test unit is realized by providing torsion by two groups of cylinders. One group of cylinders utilizes the shell rigidity test output cylinders, and the other group of cylinders is provided for the independent walking unit. When the unit is used for testing, the workpiece needs to rotate 90 degrees, and the two groups of torsion cylinders act simultaneously and are controlled synchronously. In the non-metal middle-thread-linked metal insert testing unit, a screw rod for testing is mainly grabbed by a pneumatic clamping jaw, and then a running mechanism provides tension, wherein the specification of the screw rod for testing meets the specification of the workpiece threads. The specific method for judging the position of the screw for test comprises the following steps: because of the uncertainty in the position of the threaded hole on a workpiece, such as a batch meter, it is desirable that the unit have an automatic look-up of the screw position and be grasped by the gas claw. The judgment of the screw position is that the laser sensor is used to walk up and down on two sides of the metering box, and the screw is searched. Wherein the up-and-down walking of the sensor is driven by a servo motor. The mechanical mechanism of the hinged metering box door test unit is simpler, namely only one cylinder is used for applying a pushing force to a workpiece such as the metering box door. Because the opening directions of the metering box doors are different, the workpiece is required to rotate during the test, and a proper thrust angle is found. The overall dimensions of the box determine the three degrees of freedom needed for the unit X, Y, Z, so the mechanical structure of the unit is placed on the walking beam of the impact load unit.
The mechanical structure of the impact load test station is that a load is arranged on a swinging rod, the swinging rod is supported by a bearing with a seat and can freely rotate 180 degrees, the swinging rod shaft is linked with an electromagnetic clutch, and the electromagnetic clutch is linked with a servo motor. The initial state of the swing rod is a certain angle with the horizontal plane, the swing rod is tightly held when the electromagnetic clutch is electrified, and when the electromagnetic clutch is powered off, the swing rod is separated from the clutch, so that the swing rod can perform free swinging motion, namely, impact load can perform free falling. In this embodiment, the impact load is designed into two kinds of impact blocks, which are respectively conical and circular, and the mass of each impact block is 2Kg. The impact surface is front and two sides, and the overall dimensions of the workpiece determine the unit requires X, Y, Z three degrees of freedom. When the load is in different shapes, the corresponding load needs to be replaced in advance, and the quick loading and unloading mechanism is adopted for replacement, so that time and labor are saved.
The door lock switch performance test station comprises three tests of a metering box door, a metering box door lock and a metering box electric switch. The door lock test station mainly designs two pneumatic door locks and door lock switches which respectively act, and the degree of freedom in three directions is designed because the positions of the door locks are not fixed. The door operation test mechanical mechanism adopts a structure of a sucker and a rodless cylinder to open and close the door. The sucker automatically sucks the door plate, and then the sucker hinge structure is driven by the rodless cylinder to open the door, so that the door is opened and the door is closed in opposite actions. This station requires the door to be opened, adding a centering clamping robot to the upper end of the frame. The operation test mechanical mechanism of the switch adopts a structure of a hinged connecting rod of a cylinder and a shifting fork to operate the switch. And if the door, the door lock and the switch are operated 50 times, the function of the door, the door lock and the switch is kept normal.
The mechanical structure of the sign or coating adhesion test station is designed with four degrees of freedom, X, Y, Z and direction of rotation. The rotation is mainly suitable for two wiping plates, the two wiping plates are switched by a rotary cylinder, when one solvent is wiped, the rotary cylinder acts and rotates 180 degrees, and then the other wiping plate is changed for continuous test. The mechanical structure of the coating adhesion measurement test station of the shell surface is also designed with four degrees of freedom, namely X, Y, Z and the rotation direction, and standard cross tool marks are cut according to requirements.
The general inspection or electrical performance test station can realize five tests of size measurement, electric gap and creepage distance detection, insulation resistance test, protection circuit effectiveness and dielectric performance, adopts a mechanical arm and a custom fixture to realize node fixation, and applies electrical parameters through voltage and current sources.
