DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1-4 As shown, an automated PCBA production line includes a welding section, a visual inspection section, and a testing section, wherein the welding section includes a scooping machine 2, a front lifting and loading machine 3, an automatic plug-in machine 4, a manual plug-in station 5, and a wave soldering machine 7. The scooping machine 2 is docked with a feeding track 1, and the front lifting and loading machine 3 is arranged at the exit of the scooping machine 2. The automatic plug-in machine 4, the manual plug-in station 5, and the wave soldering machine 7 are arranged in sequence behind the front lifting and loading machine 3. The feeding track 1 transports the undivided PCBA to the entrance of the scooping machine 2. A grabbing manipulator and a board separation mechanism are arranged in the scooping machine 2. The manipulator grabs the PCBA on the feeding track 1 to the board separation mechanism in the scooping machine 2. The board separation mechanism separates the PCBA. The separated PCBA is grabbed by the manipulator and placed in the front lifting and loading machine 3. A transfer manipulator and a furnace plug-in carrier are arranged in the front lifting and loading machine 3. The transfer manipulator installs the PCBA on the furnace plug-in carrier and sends it to the automatic plug-in machine 4. The automatic plug-in machine 4 Small standardized components are inserted on the PCBA. After the insertion is completed, the PCBA is transported to the welding section track 6. At the same time, the PCBA enters the manual plug-in station 5. Large and special-shaped components are manually inserted in the manual plug-in station 5. The welding section track 6 passes through the manual plug-in station 5 and enters the wave soldering machine 7. The wave soldering machine 7 solders the components plugged on the PCBA. After soldering, the PCBA enters the visual inspection section.

[0022] The visual inspection section is sequentially provided with a rear lift 8, an AOI automatic optical inspection machine 9, a transfer machine 10, and a glue dispensing machine 11. After the PCBA leaves the wave soldering machine 7, the transfer robot in the rear lift 8 removes the PCBA from the furnace plug-in carrier and transfers it to the glue dispensing fixture. The furnace plug-in carrier descends to the lower return track through the rear lift 8 and enters the front lift loader 3 through the return track. At the same time, the PCBA transferred to the glue dispensing fixture enters the AOI automatic optical inspection machine 9 for visual recognition. After the visual inspection is OK, the PCBA transferred to the glue dispensing fixture is transferred to the glue dispensing machine 11 through the transfer machine 10, and two glue dispensings are performed and two heat sinks are installed. After the glue dispensing is completed, the PCBA enters the test section.

[0023] The test section is sequentially provided with a test section pallet front elevator 12, a shielding box test machine 13, a pallet reflow elevator 14, and a test section track 15. After the PCBA enters the test section pallet front elevator 12, the transfer robot arm in the test section pallet front elevator 12 removes the PCBA from the dispensing jig and transfers it into a special test jig. The dispensing jig descends to the lower reflow track through the test section pallet front elevator 12, and returns to the rear elevator 8 through the lower reflow track. The PCBA transferred into the special test fixture is transferred into the test section track 15 by the robotic arm. The test section track 15 has two parallel tracks, and the shielding box tester 13 has four tracks, which are respectively arranged on both sides of the test section track 15. The shielding box tester 13 is provided with a robotic arm and an NG track. The robotic arm grabs the PCBA on the test section track 15 together with the special test fixture and puts them into the shielding box tester 13. After the test is completed, if the test result is NG, the robotic arm in the shielding box tester 13 will grab the PCBA together with the special test fixture and put them into the NG track inside the shielding box tester 13 for temporary storage, and they will be taken away manually and manually retested; if the test result is PASS, the robotic arm in the shielding box tester 13 will put the PCBA together with the special test fixture back on the test section track 15. The PCBA and the special test fixture enter the tray reflow elevator 14 along the test section track 15. The tray reflow elevator 14 is equipped with a robotic arm to remove the PCBA in the special test fixture. At the same time, the tray reflow elevator 14 lowers the special test fixture to the reflow track and returns to the test section elevator 12 before loading the pallet.
