[0014] The beneficial effects of the invention after adopting the above structure are: 1.

Compared with traditional flexible transmission, it can effectively eliminate gap accumulation and elastic deformation. Combined with slotted photoelectric and baffle, it can achieve precise layer detection, greatly improve the lifting and positioning accuracy, and make the support rod and auxiliary conveying components accurately aligned.

This greatly improves the overall structural rigidity and long-term operational reliability, reduces the probability of equipment failure, and ensures continuous operation of the production line.

[0017] 3. This invention can limit the feeding by setting a blocking component to ensure that the PCB board enters the position uniformly. The anti-slip sleeve on the support rod can effectively prevent the PCB board from slipping and falling off during the lifting process. The steel rope is wrapped with anti-wear rubber to reduce steel rope wear and extend service life. The multiple protection designs further improve the safety and durability of the device operation.

A baffle 414 is also provided between the outer ends of the two moving plates 44. Several slots 415 are equally spaced on the baffle 414. The baffle 414 is movably located in the slot of the slotted photoelectric sensor 316 to realize position detection and positioning signal feedback. A longitudinal plate 111 is provided at the bottom of the main frame 1, and the longitudinal plate 111 is located below the movable plate 44. The auxiliary tail assembly 5 includes a pulley 50 located at the top of the longitudinal plate 111. A pulley 51 is also provided on the inner bottom plate 14 of the main frame 1.

A steel rope 53 is provided at the bottom of the connecting plate 47 on the lower movable plate 44. The steel rope 53 passes through the pulley 50, the pulley 51 and the pulley 52 in sequence. A connecting handle 54 is provided at the end of the steel rope 53 away from the connecting plate 47. The connecting handle 54 is fixedly connected to the support plate 412. The outer side of the steel rope 53 is wrapped with anti-wear rubber 55. A feed trough 18 is provided on one side of the protective outer plate 17 corresponding to the position of the auxiliary conveying component 3. A blocking component 6 is provided on the back of the crossbar on the side of the main frame body 1 away from the feed trough 18. The blocking component 6 includes a cylinder 60 provided on the back of the crossbar, and a blocking crossbar 61 is provided on the top of the telescopic rod of the cylinder 60.

[0022] When the device is working, the external PCB board enters the device through the feed chute 18. At this time, the cylinder 60 in the blocking component 6 is activated, which drives the blocking horizontal plate 61 to rise and limit the PCB board entering, so that it accurately stops on the rotating support roller 33 of the auxiliary conveying component 3 to prevent it from deviating or rushing out. The electrical control cabinet 2 controls the start of the reducer 310. The reducer 310 drives the first external gear pulley 38 and the rotating shaft 37 to rotate through the second external gear pulley 312 and the internal gear transmission belt 313. The magnetic wheel 39 on the rotating shaft 37 rotates synchronously and drives the magnetic wheel 34 and the rotating rod 32 to rotate through magnetic coupling, thereby making the rotating support roller 33 rotate and smoothly transporting the PCB board to the top of the temporary storage station. When temporary storage and lifting are required, the speed-regulating motor 42 starts and drives the lead screw 41 to rotate in the bearing seat 40 through the coupling 43. The lead screw 41 and the lead screw nut 410 in the drive component 49 cooperate to transmit power, driving the moving plate 44 to move smoothly up and down along the guide rod 110 through the sliding sleeve 48 on the connecting plate 47. The moving plate 44 drives the fixed plate 35 and the support rod 46 to lift up and down synchronously. The support rod 46 and the rotating rod 32 are arranged alternately and can pass smoothly through the auxiliary conveying component 3 to lift or put the PCB board from the rotating support roller 33, realizing multi-layer temporary storage and up and down transmission. When the moving plate 44 moves, the baffle 414 moves along with it. The slot 415 on the baffle 414 cooperates with the slotted photoelectric sensor 316 to feed back a precise layer position signal to the controller, achieving precise positioning of 15 layers. At the same time, the connecting plate 47 pulls the steel rope 53. The steel rope 53 is driven between pulley 1 50, pulley 2 51, and pulley 3 52. Through the connecting handle 54, it pulls the support plate 412 and the tail of the support rod 46 to move synchronously, ensuring that the lifting force on both sides of the material support assembly 4 is balanced and that there is no shaking during operation. The anti-slip sleeve 413 on the support rod 46 can prevent the PCB board from slipping. The anti-wear rubber 55 on the outside of the steel rope 53 can reduce wear, improve the stability of the device operation and service life, and ultimately achieve stable, accurate and efficient up and down transmission and temporary storage of the PCB board.
