Abstract
The utility model relates to an automatic testing device for microwave leakage, which is composed of a machine hand and a control machine case. The automatic testing device for microwave leakage is controlled by a computer and is electromechanical integration. The machine hand has the movement capacity of three-dimensional space and a visual capacity and can test the position of a microwave oven on a production line and can track. The machine hand has a prompting capacity for microwave ovens exceeding a test area. The surface of a microwave oven door is divided into 62 test points by the device. The leakage value of each point can be displayed on a screen. The automatic testing device for microwave leakage has a warning function for the microwave leakage exceeding a predetermined value or other error states. The automatic testing device for microwave leakage also has a greater interference resisting capacity and is suitable for working in various environments.
Description
The utility model belongs to the microwave leakage automatic testing equipment of testing household microwave oven.
At present, this technological process of test microwave leakage is by manually-operated on the micro-wave oven production line, the work difficulty height, and accuracy is low, and flase drop and omission take place easily, influences the quality of complete machine.Simultaneously to long-term closely in this environment staff's health certain influence is arranged.
The purpose of this utility model will realize automatic test exactly, replaces the manual testing with mechanical hand, guarantees the quality of complete machine.
Automatic testing equipment of the present utility model is made up of mechanical hand, control cabinet.Computerized control, electromechanics is one.Operating personnel just can test by keyboard input various command and data.Its mechanical hand has three-dimensional locomitivity and visual capacity, can detect the position of micro-wave oven on streamline, and be followed the tracks of, and the micro-wave oven that exceeds test zone is had the prompting ability.This device is divided into 62 test points with the surface of door for microwave oven, and the leakage value of each point can both show on screen.Microwave leakage and other error condition that surpasses regulation numerical value had warning function, also have stronger antijamming capability, be fit to various environmental works.
The principle of work of microwave leakage automatic testing equipment:
The mechanical hand of this device adopts two piston-rodless cylinders, a no bucket cylinder is pressed X, Y, three directions connections of Z axle, can be in the motion of space either direction, and four microwave remote sensors are installed in the mechanical hand, best route by predetermined carries out sweep test to the door for microwave oven surface.
Mechanical hand to fire door surface scan secondary, obtains data with the movement velocity of per second 25mm.And to get bigger data be the microwave leakage value.
This device is found out maximum numerical value in 62 microwave leakage test points, with the numeric ratio of regulation, if maximal value is less than setting, it is qualified then to declare this stove, if greater than setting, then declares defective.
This device can carry out fixed test to micro-wave oven by specific (special) requirements by keyboard operation.
The technical indicator of microwave leakage automatic testing equipment:
| Test specification: measuring accuracy error: mechanical hand movement velocity: | 0～2mW/cm 2± 1.25dB 25～30mm/ second |
Specifically describe the architectural feature of this proving installation below in conjunction with accompanying drawing:
Description of drawings: Fig. 1 is the front elevation of mechanical hand, and Fig. 2 is the side view of mechanical hand, and Fig. 3 is the front elevation of control cabinet.
Microwave remote sensor 7, infrared photoelectric sensor 3 are installed on the cross of X-axis cylinder 2 and Y-axis cylinder 1 composition, the cross symbol is contained on the gear train 4, advanced by Z axle cylinder 5, the mechanical hand of Zu Chenging just can three directions move along the space like this, measures the microwave leakage of micro-wave oven.Solenoid valve 11, reduction valve 10, source of the gas two connect part 12 and are fixed on the installing plate 6.Gear train 4 and installing plate 6 are installed on the framework 8 together.Control cabinet 15 is laid electric components such as computing machine, and printer 14 and display 13 all are placed on the control cabinet.This proving installation is fit to various types of micro-wave oven leak-testings.
