The test fixture includes: the LCR tester comprises a carrier, wherein an air cylinder is fixed on the carrier, an upper clamp elastic sheet is fixed at the output end of the air cylinder, a lower clamp elastic sheet is fixed on the carrier, the lower clamp elastic sheet and the upper clamp elastic sheet are positioned on the same straight line, and the testing end of the LCR tester is electrically connected with the lower elastic sheet and the upper elastic sheet of the clamp. And the output end of the LCR tester is electrically connected with the input end of the air cylinder through a +24V electromagnetic valve. The LCR tester has four test ends, the output ends of the upper elastic sheet of the clamp and the lower elastic sheet of the clamp are two, and the four test ends of the LCR tester are respectively fixed on the four elastic sheets.

After putting electromagnetism stove coil panel on the test fixture, the LCR tester can realize automated inspection, and after the LCR tester detected the coil panel, the LCR tester can send cylinder locking instruction, and the shell fragment pushes down on the anchor clamps of test fixture upper end, and the shell fragment presss from both sides the test terminal of coil panel tightly on the upper and lower anchor clamps, and here in order to avoid crushing binding post when the cylinder action, install the telescopic link of taking elasticity below the lower shell fragment of anchor clamps. After the testing end is clamped, the multi-parameter LCR tester starts to test the Lx Q and DCR values of the product, the clamp is loosened to take away the tested product after the test is qualified, when the test is unqualified, the air cylinder of the testing clamp is in a locking state, the air cylinder is loosened only after the reset key is manually pressed, meanwhile, the system starts to detect the infrared inductor in the unqualified product placing box, when the unqualified product is placed in the unqualified product box, the system can automatically start to detect whether the coil panel is placed on the clamp, if the unqualified product is tested, the product is not placed at a specified position, and the system cannot test the next product.

The utility model provides an automatic testing arrangement of electromagnetism stove coil panel. The method has the following beneficial effects:

(1) this electromagnetism stove coil panel automatic testing device has shortened the time in whole test procedure, has simplified the product test procedure, has improved the efficiency of test. And the utility model discloses avoided the defective work to place the problem in the defective work, on keeping the basis of current test function, greatly reduced system operation personnel's technical requirement, guaranteed that the defective work can not flow in the problem in the defective work after the test is accomplished, improved the efficiency of test greatly, can provide the guarantee for the quick test of electromagnetism stove coil panel.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: an automatic testing device for an induction cooker coil panel comprises a testing clamp with a cylinder, a multi-parameter LCR tester and an infrared induction collecting box.

The testing fixture comprises a carrier 1, a cylinder 2 is fixed on the carrier 1, the output end of the cylinder 2 is located below, an upper fixture elastic sheet 3 is fixed on the output end of the cylinder 2, a lower fixture elastic sheet 4 is fixed on the carrier 1, and the lower fixture elastic sheet 4 is located right below the upper fixture elastic sheet 3.

After the coil panel of the induction cooker is placed on the test fixture, the LCR tester can realize automatic detection, and after the LCR tester detects the coil panel, the LCR tester enables the PUMP signal in the cylinder control diagram to be at a high level, at the moment, the U1 is conducted, the power supply of the control cylinder is conducted, and therefore the control cylinder is locked. The upper elastic sheet of the clamp at the upper end of the test clamp presses downwards, the upper elastic sheets of the upper clamp and the lower clamp the test terminal of the coil panel, and an elastic telescopic rod is arranged below the lower elastic sheet of the clamp in order to avoid crushing the wiring terminal when the cylinder acts.
