[0039] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0040] See also Figure 1 This embodiment provides a dual-line flexible circuit board testing system for performing a series of electrical tests on flexible circuit boards, specifically including a conveying device, several test cabinets, several transfer mechanisms and several NG material trays 4.

[0041] The conveying device includes a first conveying mechanism 101 for conveying the first material tray 501 and a second conveying mechanism 102 for conveying the second material tray 502. Optionally, the first conveying mechanism 101 and the second conveying mechanism 102 are both conveyor belts. Furthermore, the first conveying mechanism 101 and the second conveying mechanism 102 are arranged side by side, and their feeding directions are parallel.

[0042] The test cabinets are arranged at intervals along the feeding direction of the conveyor device. A plurality of test equipments are arranged in the test cabinets. The test equipments in the same test cabinet are used to perform the same electrical test items, while the test equipments in different test cabinets are used to perform different electrical test items.

[0043] The transfer mechanisms correspond one-to-one to the test cabinets. Some of the transfer mechanisms are used to transfer the flexible circuit boards on the first tray 501 to the corresponding test cabinet and transfer qualified flexible circuit boards to the second tray 502. Other transfer mechanisms are used to transfer the flexible circuit boards on the second tray 502 to the corresponding test cabinet and transfer qualified flexible circuit boards to the first tray 501.

[0044] Specifically, the several test cabinets are divided into alternately arranged first test cabinets 201 (different first test cabinets perform different electrical test items) and second test cabinets 202 (different second test cabinets perform different electrical test items). The several transfer mechanisms are divided into a first transfer component corresponding to the first test cabinet 201 and a second transfer component corresponding to the second test cabinet. The first transfer component is used to send the soft circuit board at the first material tray 501 into the corresponding first test cabinet 201, and send the soft circuit board that has passed the test into the second material tray 502; the second transfer component is used to send the soft circuit board at the second material tray 502 into the corresponding second test cabinet 202, and send the soft circuit board that has passed the test into the first material tray 501. The above-mentioned dual-line alternating operation structure can make the soft circuit board that has passed the test sent out by the previous test cabinet become the soft circuit board to be tested in the next test cabinet, thereby completing the electrical tests of a series of projects, greatly improving the test efficiency.

[0045] Optionally, the transfer mechanism includes a clamping device, a transfer platform 302, a first manipulator 303, a second manipulator 304, and a slide rail 305. The clamping device includes a first clamping mechanism 3011 for clamping the first material tray 501, a second clamping mechanism 3012 for clamping the second material tray 502, a first lifting device for driving the first clamping mechanism 3011 to move up and down, and a second lifting device for driving the second clamping mechanism 3012 to move up and down. The transfer platform 302 is located between the test cabinet and the conveying device. The first manipulator 303 is used to transfer the flexible circuit board between the clamped first material tray 501 and the transfer platform 302, and between the clamped second material tray 502 and the transfer platform 302. The second manipulator 304 is used to transfer the flexible circuit board between the transfer platform 302 and the test cabinet.

[0046] Optionally, the first manipulator 303 is a four-axis manipulator, and the second manipulator 304 is a six-axis manipulator.

[0047] In this embodiment, the test equipment in the same test cabinet is arranged in two columns, and a separation space is reserved between the two columns of test equipment. A slide rail 305 is set in the separation space, and the slide rail 305 extends along the arrangement direction of each of the test equipment. The second manipulator 304 is located above the slide rail 305 and is slidably connected to the slide rail 305 to deliver the flexible circuit board to each test equipment.

[0048] Optionally, the transfer platform 302 is also provided with a code scanning device 6 for scanning and obtaining identification information such as a QR code or barcode on the flexible circuit board for identifying the material number of the flexible circuit board, so as to record the test results in the background records related to the identification information.

[0049] In this embodiment, each transfer mechanism is provided with an NG tray 4 at one end thereof close to the conveying device. The transfer mechanism is used to transfer the unqualified flexible circuit boards to the corresponding NG tray 4 .

[0050] The dual-pipeline flexible circuit board testing system provided in this embodiment has the following specific working process:

[0051] ① At the beginning, the first conveying mechanism 101 delivers the first tray 501 filled with the flexible circuit boards to be tested, and the second conveying mechanism 102 delivers the second tray 502 empty;

[0052] ② When the first fully loaded first tray 501 arrives at the position corresponding to the first test cabinet 201, the first clamping mechanism 3011 of the corresponding first transfer assembly clamps and secures the first tray 501, and then the first lifting device lifts the first clamping mechanism 3011 together with the clamped first tray 501; similarly, when the first unloaded second tray 502 arrives at the position corresponding to the first test cabinet, the second clamping mechanism 3012 of the corresponding first transfer assembly clamps and secures the second tray 502, and then the second lifting device lifts the second clamping mechanism 3012 together with the clamped second tray 502;

[0053] ③ The first manipulator 303 transfers the flexible circuit board in the clamped first tray 501 to the barcode scanning device 6 for scanning, and then places it on the transfer platform 302;

[0054] ④ The second manipulator 304 slides along the slide rail 305 to one end close to the transfer platform 302, then picks up the flexible circuit board on the transfer platform 302, and then sends the flexible circuit board along the slide rail 305 to each test device in the first test cabinet 201 for testing the first electrical test item; since the test equipment takes time to test, and there is a time difference between each test device completing the test, the second manipulator 304 can use this time difference to continuously send the flexible circuit board to be tested to multiple test devices, thereby improving testing efficiency;

[0055] ⑤ After the first electrical test item is completed, the second manipulator 304 returns the qualified flexible circuit boards to the clamped second material tray 502, and sends the unqualified flexible circuit boards to the NG material tray 4;

[0056] ⑥ When the first material tray 501 is emptied, the first lifting device descends, the first clamping mechanism 3011 is released, and the first material tray 501 is released. The released first material tray 501 is transported downward along with the first conveying mechanism 101;

[0057] When the second material tray 502 is full, the second lifting device descends, the second clamping mechanism 3012 is released, and the second material tray 502 is released. The fully loaded second material tray 502 is then conveyed downward by the second conveying mechanism 102.

[0058] ⑦ When the released first tray 501 and the second tray 502 are transported to the second test cabinet 202, the first clamping mechanism 3011 of the corresponding second transfer assembly clamps and lifts the empty first tray 501, and the corresponding second clamping mechanism 3012 clamps and lifts the fully loaded second tray 502;

[0059] The corresponding second transfer assembly delivers the flexible circuit boards in the second tray 502 to the second test cabinet 202 for testing of the second electrical test item; that is, the qualified flexible circuit boards from the first test cabinet 201 become the flexible circuit boards to be tested in the second test cabinet 202;

[0060] ⑧ After the second electrical test item is completed, the second transfer assembly corresponding to the second test cabinet 202 places the qualified flexible circuit boards in the first material tray 501, and places the unqualified flexible circuit boards in the corresponding NG material tray 4;

[0061] ⑨ Put down the first material tray 501 and the second material tray 502 again and convey them to the next first test cabinet for inspection of the third electrical test item. At this time, the next first transfer component is used to transfer the soft circuit board in the first material tray 501 that has passed the third electrical test item to the second material tray 502. This cycle is repeated until the last electrical test item is completed in the last test cabinet, and the soft circuit boards flowing out of the conveying device are products that have passed all test items.

[0062] The dual-assembly line flexible circuit board testing system provided in this embodiment is equipped with dual conveying mechanisms to convey the flexible circuit boards to be tested and those that have been tested to each test cabinet, thereby enabling multiple test cabinets to perform electrical testing operations for different projects in sequence, reducing the degree of dependence on manpower, greatly improving testing efficiency, and having huge economic value.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
