Description

Technical Field

[0001] This utility model relates to the technical field of automated circuit board production equipment, and in particular to an automatic loading and unloading system for static testing of integrated circuit boards. Background Technology

[0002] Current static testing of integrated circuit boards relies on manual operation. This involves moving a test tray (containing ten products) to the testing machine, picking up the products with their backs facing up, scanning a QR code to send to the server, receiving confirmation that the product is ready for testing, and then placing it face up into the testing machine. The operator then shuts down the machine, presses the start button, and waits for the test to complete. Based on the results, qualified products are placed in the qualified tray, and unqualified products in the unqualified tray. With a large number of products requiring testing daily, the process involves flipping the product, scanning the back for QR codes, checking the returned information, flipping it face up again, placing it in the test fixture, and finally removing it and placing it in either the qualified or unqualified tray. Frequent human error includes missed QR code scans, placing products face down directly into the fixture after scanning the back, and misplacing qualified / unqualified products, leading to product damage, poor yield, and high scrap rates. Therefore, automation is essential. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing an automatic loading and unloading system for static testing of integrated circuit boards. This system reduces the workload of employees, significantly improves production efficiency and yield, and also reduces scrap rates, bringing great convenience to production and use.

[0004] To solve the above-mentioned technical problems, the present invention adopts an automatic loading and unloading system for static testing of integrated circuit boards, comprising: a first testing machine and a second testing machine symmetrically arranged; a first loading and unloading mechanism and a second loading and unloading mechanism arranged in front of the first and second testing machines; a six-axis robot; a material handling mechanism arranged at the front end of the six-axis robot; and a three-dimensional color camera arranged directly above the first loading and unloading mechanism and the second loading and unloading mechanism. The first testing machine is provided with a first station tested but unqualified tray, and the second testing machine is provided with a second station tested but unqualified tray. The first loading and unloading mechanism is sequentially arranged along the product transport direction with a first station loading trolley, a first station loading machine, a first station untested tray area, a first station tested qualified tray area, a first station unloading machine, and a first station unloading trolley. The second loading and unloading mechanism is sequentially arranged along the product transport direction with a second station loading trolley, a second station loading machine, a second station untested tray area, a second station tested qualified tray area, a second station unloading machine, and a second station unloading trolley.

[0005] In a preferred embodiment of the present invention, the first loading and unloading mechanism and the second loading and unloading mechanism are arranged side by side in parallel.

[0006] In a preferred embodiment of the present invention, the material handling mechanism includes a connector fixed to a six-axis robot, a follow-up detection camera disposed on the connector, a telescopic cylinder for the product to be tested, and a telescopic cylinder for the product already tested. The output end of the telescopic cylinder for the product to be tested is provided with a suction nozzle for the product to be tested, and the output end of the telescopic cylinder for the product already tested is provided with a suction nozzle for the product already tested.

[0007] In a preferred embodiment of the present invention, a lower camera is further included for acquiring the QR code on the lower surface of the product under test and sending it to the backend server.

[0008] In a preferred embodiment of the present invention, a safety fence is also included, wherein the safety fence is provided with a safety door and two sets of safety windows.

[0009] In a preferred embodiment of this utility model, the two sets of safety windows are respectively facing the first station loading machine and the second station loading machine.

[0010] The beneficial effects of this utility model are as follows: Utilizing a dual-station testing machine, each of the two testing machines uses its own independent loading-unloading track. The moving camera on the robot performs visual precision positioning of the testing machine. When a testing machine needs to be tested, the corresponding loading machine automatically separates the test tray and transports it to the working area of ​​the six-axis robot. The six-axis robot, relying on a 3D color camera fixed at the top, pre-positions the product to be tested. The robot's suction nozzle directly picks up the product and moves to the position of the lower camera. The lower camera reads the QR code and automatically uploads it to the server, receiving feedback information from the server. Simultaneously, the lower camera precisely positions the product, and the 3D color camera previously precisely positions the testing machine. The combination of these two methods accurately places the product into the testing machine, automatically shuts down the testing machine, and begins testing. Upon completion of the test, the robot automatically places the tested product into either a qualified or unqualified test tray based on the test information. Once the test tray is full, it automatically flows into the unloading machine for stacking and storage, forming a complete cycle. This reduces manual operation, improves production efficiency, and reduces the number of scrapped products. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Please see Figure 1-2 This utility model discloses an automatic loading and unloading system for static testing of integrated circuit boards, comprising: a first testing platform 22 and a second testing platform 5 symmetrically arranged; a first loading and unloading mechanism and a second loading and unloading mechanism disposed in front of the first and second testing platforms; a six-axis robot 3; a material handling mechanism disposed at the front end of the six-axis robot; and a three-dimensional color camera 14 disposed directly above the first loading and unloading mechanism and the second loading and unloading mechanism. The first testing platform is provided with a first-station untested tray 23, and the second testing platform is provided with a second-station untested tray 23. The unqualified pallet 4 is arranged in the first loading and unloading mechanism along the product transport direction, which includes a first station loading trolley 18, a first station loading machine 17, a first station pallet area to be tested 15, a first station qualified pallet area 13, a first station unloading machine 11, and a first station unloading trolley 10. The second loading and unloading mechanism along the product transport direction includes a second station loading trolley 19, a second station loading machine 20, a second station pallet area to be tested 21, a second station qualified pallet area 7, a second station unloading machine 8, and a second station unloading trolley 9.

[0016] Specifically, the material handling mechanism includes a connector 24 fixed to the six-axis robot, a follow-up detection camera 26 mounted on the connector, a telescopic cylinder 25 for the product under test, and a telescopic cylinder 27 for the product already tested. The output end of the telescopic cylinder for the product under test is equipped with a suction nozzle 29 for the product under test, and the output end of the telescopic cylinder for the product already tested is equipped with a suction nozzle 28 for the product already tested. It also includes a lower camera 6 for acquiring the QR code on the lower surface of the product under test and sending it to the backend server.

[0017] Before equipment initialization, the operator places one empty pallet in each of the following areas: the qualified pallet area 13 at the first station, the unqualified pallet area 23 at the first station, the qualified pallet area 7 at the second station, and the unqualified pallet area 4 at the second station. Pallets filled with products to be tested are fed into the first station loading machine 17 using the first station loading trolley 18, and pallets filled with products to be tested are fed into the second station loading machine 20 using the second station loading trolley 19. During initialization, the six-axis robot 3 uses the follow-up detection camera 26 to precisely detect the products sequentially. Positioning of the first station testing machine 22 and the second station testing machine 5, initialization completes and production begins. The first station loading trolley 8 separates and transports the first station test tray to the first station test tray area 15. The top-mounted 3D color camera 14 takes real-time photos and positions the first station test product within the first station test tray area 15. The six-axis robot 3 is in working mode, moving to the position and retracting the telescopic cylinder 27 of the tested product, while simultaneously extending the telescopic cylinder 25 of the test product, using the test product to suction... The six-axis robot 3 picks up the product to be tested from the first test tray area 15 at the first station using nozzle 29. It then moves above the lower camera 6 to take a picture, obtaining the QR code on the lower surface of the product and sending it to the server. Simultaneously, it obtains the precise positioning of the lower surface of the product. The robot then moves to the first station testing machine 22, reads the data just returned from the server, and places the product to be tested into the testing machine 22 to begin testing. The robot returns to its safe position and waits for the testing machine 22 to complete the test. Once the test is complete, the robot switches to working mode, retracting the product-to-test telescopic cylinder 25 and extending the tested product telescopic cylinder 27. It uses the tested product suction nozzle 28 to pick up the tested product from the first station. If the tested product is qualified, the robot places it in the qualified test tray area 13. If the tested product is unqualified, the robot places it in the unqualified test tray area 23. The robot then returns to its safe position, and this cycle repeats.

[0018] Specifically, it also includes a safety fence 1, which has a safety door 2, a left safety window 16, and a right safety window 12. The two sets of safety windows face the first station loading machine and the second station loading machine, respectively. When there are no products to be tested in the first station test pallet area 15, the qualified pallets in the first station already tested pallet area 13 are preferentially transferred to the first station unloading machine 11 for storage. The vacated first station already tested pallet area 13 receives the empty pallets in the first station test pallet area 15. The vacated first station test pallet area 15 receives the new test pallets from the first station loading machine 17. Finally, the first station unloading trolley 10 is used manually to collect the products. The first qualified pallet in the first station of the unloading machine 11 is simultaneously transported by the independent second station loading trolley 19 to the second station test pallet area 21. A top-mounted 3D color camera 14 takes real-time photos and positions the product to be tested in the second station test pallet area 21. The six-axis robot 3 is in working mode and moves to the second station test pallet area 21, retracting the telescopic cylinder 27 of the tested product and extending the telescopic cylinder 25 of the product to be tested. The product suction nozzle 29 is used to pick up the product to be tested from the second station test pallet area 21. The six-axis robot 3 moves above the lower camera 6 to take photos, obtaining the two-dimensional image of the lower surface of the product to be tested in the second station. The QR code is sent to the server, and the precise positioning position of the lower surface of the product under test at the second station is obtained. The six-axis robot 3 moves to the second station testing machine 5, reads the data just returned by the server, and places the product under test into the second station testing machine 5 to start testing. The six-axis robot 3 returns to the safety point and waits for the second station testing machine 5 to complete the test. The six-axis robot 3 is now in working state. At the same time, it retracts the telescopic cylinder 25 of the product under test and extends the telescopic cylinder 27 of the tested product. It uses the tested product suction nozzle 28 to pick up the tested product from the second station. If the tested product result at the second station is qualified, the six-axis robot 3 places it in the qualified tested tray area 7 of the second station. If the product test result is unqualified, the six-axis robot 3 places the unqualified pallet 4 in the second station and then returns to the safe position. This cycle repeats. When there are no products to be tested in the pallet area 21 of the second station, the qualified pallets in the qualified pallet area 7 of the second station are prioritized to flow into the unloading machine 8 of the second station for storage. The qualified pallet area 7 of the second station in the empty position receives the empty pallets in the pallet area 21 of the second station. The unqualified pallet area 21 of the second station in the empty position receives the new pallets to be tested from the loading machine 20 of the second station. Finally, the qualified pallets of the second station are manually removed from the unloading machine 8 by the unloading trolley 9 of the second station.
