Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The flexible circuit board test fixture reflow system shown in fig. 1 comprises an upper layer belt line 10 and a lower layer belt line 20 which flow in opposite directions, wherein a plurality of fixture positioning mechanisms 30 which are arranged at equal intervals are arranged on a base of the upper layer belt line 10; the jig positioning mechanism 30 includes two optical fiber sensors fixed on the base, two positioning columns 31 located below the belt, and an air cylinder 32 driving the positioning columns 31 to ascend and descend. The top of the base of the upper layer belt line 10 is provided with a limiting block 33 on each of two sides of the jig positioning mechanism 30, and a distance for the test jig to pass is formed between the limiting block 33 and the base. The base is provided with a bracket for mounting the test equipment at the position closest to the end jig positioning mechanism 30. The initial ends of the upper layer belt line 10 and the lower layer belt line 20 are respectively provided with a first jig pushing mechanism 40 and a second jig pushing mechanism 50; the initial end and the tail end of the lower-layer belt line 20 are respectively provided with a first lifting table 60 and a second lifting table 70, one side of the top table board of the first lifting table 60 and the second lifting table 70, which is opposite to the lower-layer belt line 20, is provided with a baffle, and a pressure sensor is installed in the baffle.

The test fixture A with the flexible circuit board in the upper layer belt line 10 flows from the initial end to the tail end, and when the test fixture cuts off the optical fiber signal in the fixture positioning mechanism 30 positioned below the test equipment, the cylinder 32 drives the positioning column 31 to ascend and insert at the bottom of the fixture to lift the fixture by a height to separate the fixture from the belt line; after the flexible circuit board in the test fixture is tested, the flexible circuit board is taken away manually or by a mechanical arm, and the empty test fixture returns to the upper layer belt line 10 and comes to the first lifting platform 60 at the tail end along with the upper layer belt line 10; when the test fixture impacts the baffle and is captured by the pressure sensor, the first lifting table 60 descends to the lower layer belt line 20; the second jig pushing mechanism 50 positioned at the initial end of the lower-layer belt line 20 pushes the test jig on the first lifting table 60 onto the lower-layer belt line 20; the lower-layer belt line 20 conveys the empty test fixture to the second lifting table 70 at the tail end, and when the test fixture impacts the baffle and is captured by the pressure sensor, the second lifting table 70 is lifted to the initial end of the upper-layer belt line 10; after a new flexible circuit board to be tested is placed on the test fixture manually or by a mechanical arm, the fixture pushing mechanism 50 pushes the test fixture into the upper layer belt line 10.
