[0019] Reference Figures 1 to 3 According to the present invention, a testing and marking production device includes a testing and marking machine 100, a frame 200, and a loading and unloading mechanism 300. The testing and marking machine 100 is provided with a testing and marking workbench 110. The frame 200 is arranged on one side of the testing and marking machine 100, and a first guide rail 210 is fixedly installed on the frame 200. The frame 200 is provided with a loading workbench and a unloading workbench 220 for placing circuit boards 600. Along the extension direction of the first guide rail 210, the unloading workbench, the unloading workbench 220, and the testing and marking workbench 110 are arranged sequentially. The loading and unloading mechanism 300 includes a mounting frame and a first drive mechanism. The structure includes structure 310, first suction cup module 320, and second suction cup module 330. The mounting frame is slidably connected to the first guide rail 210. The first drive structure 310 is connected to the mounting frame and can drive the mounting frame to move horizontally along the first guide rail 210. The first suction cup module 320 and the second suction cup module 330 are both mounted on the mounting frame and can move up and down to pick up or release the circuit board 600. The first suction cup module 320 can move the circuit board 600 from the loading worktable 220 to the testing and marking worktable 110, and the second suction cup module 330 can move the circuit board 600 from the testing and marking worktable 110 to the unloading worktable.

[0020] It is understood that the testing and marking production device provided in this embodiment of the present invention, by arranging the loading workbench 220, the testing and marking workbench 110, and the unloading workbench sequentially along the first guide rail 210, and in conjunction with the loading and unloading mechanism 300 equipped with a dual suction cup module, realizes the fully automated flow of the circuit board 600 from loading, testing and marking to unloading, without the need for manual intervention, significantly improving production efficiency and automation level. The loading and unloading mechanism 300 integrates the first suction cup module 320 and the second suction cup module 330, which can simultaneously perform loading and unloading actions. While the first suction cup module 320 moves the circuit board 600 to be tested from the loading workbench 220 to the testing and marking workbench 110, the second suction cup module 330 can move the circuit board 600 that has completed testing and marking from the testing and marking workbench 110 to the unloading workbench, realizing synchronous operation of "up and down one", effectively shortening the work cycle and improving the overall production rhythm. The test marking production device provided in this embodiment of the utility model can realize fully automatic, continuous and high-efficiency production of circuit board 600 from loading, test marking to unloading, thereby improving the automation level and overall capacity of the production line.

[0021] Furthermore, in this embodiment of the invention, the frame 200 and the testing and marking machine 100 are arranged side by side, with each functional workbench linearly arranged, resulting in a compact structure that facilitates equipment integration and production line layout. Simultaneously, the mounting frame, slidably mounted on the first guide rail 210, completes all transfer actions in a single direction, resulting in a simple movement path, reduced ineffective travel, and improved space utilization efficiency and operational stability. The loading and unloading mechanism 300 precisely controls the movement of the mounting frame along the guide rail through the first drive structure 310, and, combined with the lifting action of the suction cup module, achieves precise gripping and placement of the circuit board 600, effectively avoiding offset or collision during handling, ensuring the safety of the circuit board 600 and the accuracy of testing and marking. The modularly designed loading and unloading mechanism 300 is mounted on a sliding mounting frame, facilitating debugging and maintenance. Furthermore, the suction cup module can adapt to circuit boards 600 of different sizes and types; simply adjusting the suction cup layout or parameters can meet the needs of multi-variety production, demonstrating excellent flexibility and versatility.

[0022] Furthermore, refer to Figure 1 and Figure 2According to some embodiments of the present invention, the mounting bracket includes a second guide rail 340, a support plate 350, and a second drive structure 360. The second guide rail 340 is parallel to and slidably connected to the first guide rail 210. The first drive structure 310 is connected to the second guide rail 340 and can drive the second guide rail 340 to move horizontally along the first guide rail 210. The support plate 350 is slidably connected to the second guide rail 340. The first suction cup module 320 and the second suction cup module 330 are both mounted on the support plate 350. The second drive structure 360 ​​is mounted on the second guide rail 340 and connected to the support plate 350. The second drive structure 360 ​​can drive the support plate 350 to move horizontally along the second guide rail 340.

[0023] Understandably, by setting a second guide rail 340 parallel to the first guide rail 210 in the mounting frame, and mounting the first suction cup module 320 and the second suction cup module 330 on a support plate 350 that can move along the second guide rail 340, a spatial decoupling design for loading and unloading operations is achieved. Specifically, the first guide rail 210 is used to drive the entire mounting frame to move horizontally over a wide range between the loading worktable 220, the unloading worktable, and the testing and marking worktable 110, while the second guide rail 340 is used to drive the suction cup modules to independently extend into or out of the testing and marking worktable 110 area within a local range.

[0024] This structural design eliminates the need for the mounting bracket to extend completely above the testing and marking workbench 110. Instead, the first drive structure 310 drives the second guide rail 340 to move along the first guide rail 210 and extend above the testing and marking workbench 110, bringing the support plate 350 along with the suction cup module into the testing area for loading and unloading. Once completed, the bracket can be retracted, preventing the large mounting bracket from occupying testing space for extended periods. This effectively prevents mechanical interference between the loading / unloading mechanism 300 and the testing and marking machine 100 during operation, ensuring the safe and stable operation of the testing and marking process. Simultaneously, it provides ample space for the operation and maintenance of the testing equipment, improving the overall coordination and safety of the machine.

[0025] Furthermore, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the first suction cup module 320 includes a sixth driving structure 321, a first support frame 322 and a plurality of first vacuum suction cups 323. The sixth driving structure 321 is mounted on the support plate 350. The sixth driving structure 321 is connected to the first support frame 322 and can drive the first support frame 322 to move up and down. The plurality of first vacuum suction cups 323 are evenly spaced at the bottom of the first support frame 322.

[0026] Understandably, the first suction cup module 320 uses the sixth drive structure 321 to drive the first support frame 322 to move up and down, and multiple first vacuum suction cups 323 are evenly arranged at the bottom of the first support frame 322, achieving stable and uniform adsorption of the circuit board 600 to be tested. The evenly distributed vacuum suction cups can effectively prevent the circuit board 600 from tilting or falling off due to uneven local force, which is especially suitable for large-sized or heavy circuit boards 600. At the same time, the independently controlled lifting structure (sixth drive structure 321) allows the first vacuum suction cups 323 to be flexibly adjusted according to the difference in workstation height, improving adaptability and operational reliability.

[0027] Furthermore, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the second suction cup module 330 includes a seventh drive structure, a second support frame and a plurality of second vacuum suction cups. The seventh drive structure is mounted on the support plate 350. The seventh drive structure is connected to the second support frame and can drive the second support frame to move up and down. The plurality of second vacuum suction cups are evenly spaced at the bottom of the second support frame.

[0028] Understandably, the second suction cup module 330 is structurally symmetrical and functionally independent of the first suction cup module 320. Through the seventh drive structure, it drives the second support frame and multiple second vacuum suction cups to move up and down, ensuring that the circuit board 600, after testing and marking, is smoothly and reliably removed from the testing and marking workbench 110 and transferred to the unloading area. The independent lifting design of the dual modules ensures that the loading and unloading actions do not interfere with each other, supporting synchronous operation and further improving production cycle time. Simultaneously, the multi-point vacuum adsorption method enhances stability during handling, preventing the circuit board 600 from shaking or shifting during movement.

[0029] Furthermore, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the loading workbench 220 is provided with a lifting mechanism 400. The lifting mechanism 400 includes a top plate 410 and a third drive structure 420. The top plate 410 is used to support the circuit board 600, and the third drive structure 420 is connected to the top plate 410 and can drive the top plate 410 to move up and down.

[0030] Understandably, the loading workbench 220 is equipped with a lifting mechanism 400, which uses a third drive structure 420 to move the top plate 410 up and down, thereby lifting the stacked circuit boards 600 one by one to the predetermined gripping height. This design realizes an automatic feeding function, avoiding frequent manual adjustments to the loading position, ensuring that the circuit board 600 is at the optimal height each time it is gripped, improving the success rate of suction cup gripping and repeatability accuracy, while reducing frictional damage to the underlying structure of the circuit board 600, and enhancing the automation and safety of the loading process.

[0031] Furthermore, refer to Figure 1 and Figure 3 According to some embodiments of the present invention, the loading workbench 220 is provided with a positioning mechanism 500. The positioning mechanism 500 includes a first positioning plate 510, a second positioning plate 520, a first pushing module, and a second pushing module. The first positioning plate 510 and the second positioning plate 520 are both fixedly connected to the loading workbench 220, and the first positioning plate 510 and the second positioning plate 520 are perpendicular to each other. The first pushing module can push the circuit board 600 located at the top toward the first positioning plate 510, and the second pushing module can push the circuit board 600 located at the top toward the second positioning plate 520.

[0032] Understandably, the addition of a positioning mechanism 500, consisting of a first positioning plate 510, a second positioning plate 520, and corresponding pushing modules, to the loading workbench 220 enables dual alignment correction of the topmost circuit board 600 in the X and Y directions before each loading. By pushing the circuit board 600 towards two mutually perpendicular reference surfaces using the first and second pushing modules respectively, a "corner positioning" effect is achieved. This significantly eliminates the positional offset of the circuit board 600 caused by stacking deviations or feeding errors, ensuring accurate subsequent testing and marking, and stable handling, effectively improving the overall processing accuracy and product consistency.

[0033] Furthermore, refer to Figure 3 According to some embodiments of the present invention, the first pushing module includes a first pushing block 530 and a fourth driving structure 540. The fourth driving structure 540 is connected to the first pushing block 530 and drives the first pushing block to move closer to or away from the circuit board 600. The second pushing module includes a second pushing block 550 and a fifth driving structure 560. The fifth driving structure 560 is connected to the second pushing block 550 and drives the second pushing block to move closer to or away from the circuit board 600.

[0034] Understandably, the first and second pushing modules employ a fourth driving structure 540 and a fifth driving structure 560, respectively, to drive the first pusher 530 and the second pusher 550. This design features a simple structure, rapid response, and highly controllable extension and retraction of the pushers. This design achieves precise and gentle positioning of the circuit board 600, avoiding scratches on the board surface or damage to components caused by rigid impacts. Furthermore, the pneumatic or electric drive method facilitates integrated control, allowing for linkage with the loading and unloading process to achieve fully automatic alignment and positioning, thus improving the system's intelligence and operational reliability.

[0035] Furthermore, refer to Figure 1According to some embodiments of the present invention, the unloading workbench includes a good product workbench and a defective product workbench 240 arranged sequentially along the extension direction of the first guide rail 210, and the second suction cup module 330 is capable of moving the circuit board 600 from the test and marking workbench 110 to the good product workbench or the defective product workbench 240.

[0036] Understandably, the unloading workbench is divided into a good product workbench and a defective product workbench 240, arranged sequentially along the conveying direction. This allows the second suction cup module 330 to intelligently select the unloading path based on test results, automatically classifying and storing qualified and unqualified products. This design achieves automatic sorting, avoiding errors and delays caused by manual judgment and sorting, improving production management efficiency and quality traceability, and facilitating the connection with subsequent processes. It is a crucial link in achieving fully automated production.

[0037] The following provides a further explanation of the specific workflow of the testing and marking production device provided in this embodiment of the present invention: In step S1, the circuit boards 600 to be tested are stacked on the loading table 220, and the lifting mechanism 400 lifts the top circuit board 600 to a preset height. The first pushing module and the second pushing module operate respectively, pushing the circuit board 600 against the first positioning plate 510 and the second positioning plate 520, which are perpendicular to each other, through the first pushing block 530 and the second pushing block 550, to achieve precise positioning in both X and Y directions and ensure that the picking position is consistent. Then, the second driving structure 360 ​​drives the support plate 350 to move along the second guide rail 340, thereby driving the first suction cup module 320 to move directly above the loading table 220. Then, the sixth driving structure 321 drives the first support frame 322 to move so that the first vacuum suction cup 323 can pick up the top circuit board 600 to be tested and lift it. Step S2: After the circuit board 600 on the test marking workbench 110 has completed testing and marking, the first drive structure 310 drives the second guide rail 340 to move along the first guide rail 210 to extend above the working range of the test marking workbench 110. Then, the second drive structure 360 ​​drives the support plate 350 to move along the second guide rail 340, thereby driving the second suction cup module 330 to move directly above the test marking workbench 110. Subsequently, the seventh drive structure drives the second support frame to move so that the second vacuum suction cup can adsorb the circuit board 600 that has completed the test and lift it up. In step S3, after the second suction cup module 330 completes the material picking, the second drive structure 360 ​​drives the support plate 350 to move along the second guide rail 340, thereby driving the first suction cup module 320 to move directly above the test marking workbench 110. Subsequently, the sixth drive structure 321 drives the first support frame 322 to move so that the first vacuum suction cup 323 can place the circuit board 600 to be tested on the test marking workbench 110 and reset it. In step S4, after the circuit board 600 to be tested is placed, the first drive structure 310 drives the second guide rail 340 to move along the first guide rail 210 to exit the test marking machine 100. Then, according to the test result signal, with the cooperation of the first drive structure 310 and the second drive structure 360, the second suction cup module 330 is driven to place the tested circuit board 600 on the good product workbench or the defective product workbench 240. Finally, it is reset. At the same time as the tested circuit board 600 is placed, the test marking machine 100 starts the test marking program.

[0038] The above workflow is precisely scheduled by the control system to proceed in a continuous cycle. The control system can be a PLC control system, and no specific limitation is made here.

[0039] It should be noted that, in the embodiments of this utility model, the first drive structure 310, the second drive structure 360, the third drive structure 420, the fourth drive structure 540, the fifth drive structure 560, the sixth drive structure 321 and the seventh drive structure can be constructed using telescopic cylinders, slide cylinders, lead screw motors, etc., and can be determined according to the actual situation, without specific limitations here.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
