[0002] Circuit boards, also known as PCBs, play a crucial role in the mass production of fixed circuits and the optimization of electrical appliance layout. With the increasing demands for multi-functionality, miniaturization, and high performance in electronic products, printed circuit boards are evolving towards higher layering, higher density, and thinner cores. In the production process of printed circuit boards, surface mount technology (SMT) is an important component of PCB processing technology, and solder paste printing is the first and most critical step in SMT.

Detailed Implementation

[0025] like Figure 1-5 As shown, an automatic circuit board loading machine includes a mounting frame 1 and a support leg 2 connected to the bottom of the mounting frame 1.

[0026] A transverse frame 3 is mounted on the mounting bracket 1 via a transverse moving assembly. The transverse moving assembly includes two symmetrically arranged transmission components connected to the inner wall of the mounting bracket 1. The two transmission components are connected by a rotating shaft 6, which is controlled to rotate by a drive assembly. The bottom ends of the transverse frame 3 are fixed to the transmission components. A guide rail 7 is provided on one side of each transmission component, and a slider 8 is slidably connected to the guide rail 7. The slider 8 is fixedly connected to the bottom of the transverse frame 3. The drive assembly drives the transmission components to rotate, thereby causing the transverse frame 3 to move laterally.

[0027] The bottom of the transverse frame 3 is connected to a longitudinal moving component. The longitudinal moving component includes a second transmission component connected in a groove at the bottom of the transverse frame 3. The second transmission component is controlled to rotate by a second drive component connected to the transverse frame 3. The bottom of the second transmission component is connected to a support frame 9. The bottom of the support frame 9 is connected to two symmetrically arranged longitudinal moving frames 10. The top of the longitudinal moving frame 10 is connected to a second slider 11. The second slider 11 is slidably connected to a second guide rail 12. The second guide rail 12 is connected to the transverse frame 3 by a fixing component.

[0028] The fixing assembly includes several irregular rods 13, one end of which is fixed to the side wall of the transverse frame 3, and the other end of each of the irregular rods 13 is connected to the fixing plate 14. The guide rail 12 is connected to the fixing plate 14.

[0029] The drive component 2 drives the transmission component 2 to rotate, thereby driving the support frame 9 to move longitudinally, and in turn driving the two longitudinal moving frames 10 to move longitudinally.

[0030] Both transmission assembly one and transmission assembly two include two displacement pulleys and a displacement belt connected to the two displacement pulleys. The two displacement pulleys in transmission assembly one are fixed to the mounting frame 1. The bottom ends of both ends of the transverse frame 3 are respectively fixed to the two displacement belts in transmission assembly one. The two ends of the rotating shaft 6 are fixed to the two displacement pulleys. The rotating shaft 6 is controlled to rotate by the drive assembly one. The two displacement pulleys in transmission assembly two are fixed to the bottom of the transverse frame 3. The top of the support frame 9 is fixedly connected to the displacement belt in transmission assembly two. One of the displacement pulleys in transmission assembly two is controlled to rotate by the drive assembly two.

[0031] Both drive assembly one and drive assembly two include a drive motor, a driving pulley, and a driven pulley. The driving pulley and the driven pulley are connected by a drive belt. The driving pulley is connected to the output end of the drive motor. The driven pulley on drive assembly one is fixed on the rotating shaft 6, and the drive motor on drive assembly one is fixed on the mounting bracket 1. The drive motor on drive assembly two is connected to the transverse frame 3. A rotating shaft 2 is connected to the driven pulley on drive assembly two. The end of the rotating shaft 2 passes through a through hole in the side wall of the transverse frame 3 and is connected to one of the displacement pulleys in transmission assembly two.

[0032] Lifting components are installed on both sides of the longitudinal movement assembly. Each lifting component includes a lead screw slide module 15 and an intermediate plate 16. The intermediate plate 16 is fixed to the outer wall of the second slider 11 and the longitudinal movement frame 10. The slide of the lead screw slide module 15 is fixedly connected to the end face of the intermediate plate 16 away from the second slider 11. The bottom of the lead screw slide module 15 is connected to the adsorption assembly. By moving the slide in the lead screw slide module 15 up and down, since the slide is fixed to the outer wall of the slider 11 and the longitudinal movement frame 10, the slider 11 and the longitudinal movement frame 10 cannot move vertically, thus keeping the slide stationary and allowing the lead screw slide module 15 to move up and down.

[0033] The bottom of the lifting assembly is connected to an adsorption assembly, which includes a base frame 17. The base frame 17 is connected to the bottom of the lead screw slide module 15. Several pneumatic suction cups 18 are connected below the base frame 17 to hold the circuit board.

[0034] The cleaning components are connected to both sides of the base frame 17. Each cleaning component includes an extension plate 19 connected to the base frame 17, an L-shaped plate 20 connected to the extension plate 19, and a T-shaped plate 21 connected to the other end of the L-shaped plate 20 facing downwards. The T-shaped plate 21 has a through hole, and a high-pressure jet nozzle 22 is installed inside the through hole. The high-pressure jet nozzles 22 on the two sets of cleaning components are arranged opposite each other. When the pneumatic suction cup 18 picks up the circuit board, the high-pressure jet nozzle 22 blows air laterally onto the circuit board, thereby cleaning the surface of the circuit board.

[0035] An automatic lifting platform 4 is provided below the adsorption component. Circuit boards are stacked on the automatic lifting platform 4. A belt conveyor 5 is provided on one side of the automatic lifting platform 4.

[0036] The operation process of this utility model is as follows:

[0037] In use, the circuit board is placed on the automatic lifting platform 4, and the height is adjusted by the automatic lifting platform 4. Then, the drive component one drives the displacement belt in the transmission component one to rotate, thereby driving the transverse frame 3 to move laterally through the slider one 8 until the pneumatic suction cup 18 is placed above the circuit board. Then, the screw slide module 15 works to lower the base frame 17 until the pneumatic suction cup 18 presses on the circuit board. Then, the pneumatic suction cup 18 works to hold the circuit board. Then, the screw slide module 15 works to drive the base frame 17 to rise and reset. Then, the drive component two drives the displacement belt in the transmission component two to rotate, thereby driving the longitudinal frame 10 to move longitudinally through the support frame 9 until the pneumatic suction cup 18 is placed above the belt conveyor 5. Then, the screw slide module 15 works to drive the pneumatic suction cup 18 to descend until the circuit board is 1cm above the belt conveyor. Then, the pneumatic suction cup 18 works to lower the circuit board, so that the circuit board falls onto the belt conveyor and is transported away for loading.
