The first loading lifting platform 701 is used to provide a loading tray 503 fully loaded with flexible circuit boards to the loading conveyor belt 702; the loading conveyor belt 702 is used to transport the loading tray 503 to the second loading lifting platform 703; the second loading lifting platform 703 is used to collect the empty loading tray 503; the first loading robot 704 is used to transfer the flexible circuit board on the loading tray 503 to the loading slide block 705; the loading slide block 705 is used to transfer the flexible circuit board from the first loading robot 704 to the second loading robot 706; the second loading robot 706 is used to transfer the flexible circuit board from the loading slide block 705 to the first loading tray 501.

[0062] The unloading device includes a first unloading lifting platform 801, an unloading conveyor belt 802, a second unloading lifting platform 803, a first unloading manipulator 804, an unloading slider 805, and a second unloading manipulator 806. The first unloading lifting platform 801 is used to provide an empty unloading tray 504 to the unloading conveyor belt 802; the unloading conveyor belt 802 is used to transport the unloading tray 504 to the second unloading lifting platform 803; the second unloading lifting platform 803 is used to collect the unloading tray 504 fully loaded with flexible circuit boards; the first unloading manipulator is used to transfer the flexible circuit board from the conveying device to the unloading slider 805; the unloading slider 805 is used to transfer the flexible circuit board from the first unloading manipulator to the second unloading manipulator 806; the second unloading manipulator 806 is used to transfer the flexible circuit board from the unloading slider 805 to the unloading tray 504.

[0063] The conveying mechanism further includes a reflux conveying mechanism 105, a tray supply lifting platform 103 and a tray closing lifting platform 104. The reflux conveying mechanism 105 is located below the first conveying mechanism 101 and the second conveying mechanism 102, and the feeding directions of the first conveying mechanism 101 and the second conveying mechanism 102 are opposite to those of the reflux conveying mechanism 105. The tray supply lifting platform 103 is used to transfer the empty trays from the outlet of the reflux conveying mechanism 105 to the inlet of the first conveying mechanism 101 and the second conveying mechanism 102; the tray closing lifting platform 104 is used to recover the empty trays at the outlets of the first conveying mechanism 101 and the second conveying mechanism 102.

[0064] The test cabinets are arranged at intervals along the feeding direction of the conveying device. The test cabinets are provided with a plurality of test equipments, the test equipments in the same test cabinet are used to perform the same electrical test items, and the test equipments in different test cabinets are used to perform different electrical test items.

[0065] The transfer mechanism corresponds to the test cabinet one by one. Some of the transfer mechanisms are used to send the soft circuit boards at the first tray 501 to the corresponding test cabinet, and send the soft circuit boards that have passed the test to the second tray 502; some of the transfer mechanisms are used to send the soft circuit boards at the second tray 502 to the corresponding test cabinet, and send the soft circuit boards that have passed the test to the first tray 501.

[0066] Specifically, the plurality of 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 plurality of 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 above-mentioned double-assembly 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 a series of electrical tests of the project, which greatly improves the test efficiency.

[0067] 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, and the second manipulator 304 is used to transfer the flexible circuit board between the transfer platform 302 and the test cabinet.

[0068] Optionally, the first manipulator 303 is a four-axis manipulator, and the second manipulator 304 is a six-axis manipulator.

[0069] In this embodiment, the test equipment in the same test cabinet is arranged in two columns, and a spacing space is reserved between the two columns of test equipment. A slide rail 305 is set in the spacing 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 so as to deliver the flexible circuit board to each test equipment.

[0070] 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 a 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.

[0071] In this embodiment, each transfer mechanism is provided with an NG tray 4 at one end close to the conveying device. The transfer mechanism is used to transfer the unqualified flexible circuit boards to the corresponding NG tray 4 .

[0072] The fully automatic test production system for flexible circuit boards provided in this embodiment has the following specific working process:

[0073] (1) At the beginning, the first loading lifting platform 701 is lowered to the lowest position, and the second loading lifting platform 703 is raised to be flush with the loading conveyor belt 702, and a plurality of loading trays 503 filled with flexible circuit boards to be tested are stacked and placed on the first loading lifting platform 701;

[0074] (2) The first loading lifting platform 701 delivers the fully loaded loading tray 503 to the loading conveyor belt; it can be understood that each time a loading tray 503 is delivered to the loading conveyor belt, the first loading lifting platform 701 rises a little to deliver the next loading tray 503 to the loading conveyor belt;

[0075] At the same time, the tray lift 103 delivers the empty first tray 501 to the first conveying mechanism 101, and delivers the empty second tray 502 to the second conveying mechanism 102; similarly, each time a tray is delivered to the conveying device, the tray lift 103 rises a little to deliver the next tray to the conveying device;

[0076] At the same time, the first unloading lifting platform 801 delivers the empty unloading tray 504 to the unloading conveyor belt 802; similarly, each time a lower unloading tray 504 is delivered to the unloading conveyor belt, the first unloading lifting platform 801 rises a little to deliver the next lower unloading tray 504 to the unloading conveyor belt;

[0077] (3) The loading conveyor belt transports the fully loaded loading tray 503 to a position close to the first loading robot 704. The first loading robot 704 transfers the flexible circuit board in the loading tray 503 to the loading slider 705. The loading slider 705 slides toward the end close to the second loading robot 706. The second loading robot 706 places the flexible circuit board from the loading slider 705 into the first tray 501 of the first conveying mechanism 101. At this time, the first conveying mechanism 101 delivers the first tray 501 full of flexible circuit boards to be tested, and the second conveying mechanism 102 delivers the empty second tray 502.

[0078] (4) When the first fully loaded first material 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 fixes the first material tray 501, and then the first lifting device lifts the first clamping mechanism 3011 together with the clamped first material tray 501; similarly, when the first unloaded second material 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 fixes the second material tray 502, and then the second lifting device lifts the second clamping mechanism 3012 together with the clamped second material tray 502;

[0079] (5) The first manipulator 303 transfers the flexible circuit board in the clamped first tray 501 to the barcode scanning device 6 for barcode scanning, and then places it on the transfer platform 302;

[0080] (6) 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 to test the first electrical test item; since the test equipment test takes time, and there is a time difference between each test equipment to complete the test, the second manipulator 304 can use the time difference to continuously send the flexible circuit board to be tested to multiple test equipment, thereby improving the test efficiency;

[0081] (7) After the first electrical test item is completed, the second manipulator 304 returns the qualified flexible circuit board to the clamped second material tray 502, and sends the unqualified flexible circuit board to the NG material tray 4;

[0082] (8) 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;

[0083] 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 transported downward along with the second conveying mechanism 102.

[0084] (9) 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 next second clamping mechanism 3012 clamps and lifts the fully loaded second tray 502;

[0085] The corresponding second transfer assembly delivers the flexible circuit board in the second material tray 502 to the second test cabinet 202 for testing the second electrical test item; that is, the qualified flexible circuit board from the first test cabinet 201 becomes the flexible circuit board to be tested in the second test cabinet 202;

[0086] (10) After the second electrical test item is tested, 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;

[0087] (11) Put down the first material tray 501 and the second material tray 502 again and convey them to the next first test cabinet for 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, and the cycle is repeated until the last electrical test item is completed in the last test cabinet, and the soft circuit board flowing out of the conveying device is a product that has passed all the test items. It can be understood that if the number of test cabinets is odd, then after the last electrical test, the first material tray 501 is empty and the second material tray 502 is fully loaded; if the number of test cabinets is even, then after the last electrical test, the first material tray 501 is fully loaded and the second material tray 502 is empty;

[0088] (12) The first unloading robot transfers the flexible circuit board in the fully loaded first material tray 501 or the second material tray 502 to the unloading slider 805, and the unloading slider 805 slides toward the second unloading robot 806, and the second unloading robot 806 transfers the flexible circuit board to the empty unloading material tray 504 on the unloading conveyor belt 802;

[0089] After the fully loaded first material tray 501 or the second material tray 502 is emptied, only the empty first material tray 501 and the second material tray 502 are left at the end of the conveying device; the closing tray lifting platform 104 lowers the received empty first material tray 501 and the second material tray 502 to be flush with the reflux conveying mechanism 105, and then delivers the first material tray 501 and the second material tray 502 to the reflux conveying mechanism 105;

[0090] The tray supply lifting platform 103 is lowered to be flush with the return conveying mechanism 105 so as to receive the first tray 501 and the second tray 502 sent from the return conveying mechanism 105. After receiving the trays, the tray supply lifting platform 103 rises to be flush with the first conveying mechanism 101 and the second conveying mechanism 102, and sends the first tray 501 and the second tray 502 into the first conveying mechanism 101 and the second conveying mechanism 102 respectively, thereby realizing the cyclic supply of the first tray 501 and the second tray 502;

[0091] (13) After the unloading tray 504 is fully loaded, the unloading conveyor belt 802 sends the unloading tray 504 to the second unloading lifting platform 803, and the second unloading lifting platform 803 is lowered a little to receive the next fully loaded unloading tray 504; when the second unloading lifting platform 803 is lowered to the lowest position, the stacked unloading tray 504 fully loaded with flexible circuit boards can be taken out and enter the next production process.

[0092] The fully automatic testing and production system for flexible circuit boards provided in this embodiment is equipped with a dual conveying mechanism 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 carry out electrical testing operations of different projects in sequence, reducing the degree of dependence on manpower, greatly improving the testing efficiency, and having huge economic value.

[0093] 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 the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
