Description

Technical Field

[0001] The utility model relates to the technical field of circuit board storage, in particular to a printed circuit board storage rack. Background Art

[0002] PCB, whose Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Printed circuit boards have developed from single-layer to double-sided, multi-layer and flexible, and still maintain their own development trends. Due to the continuous development towards high precision, high density and high reliability, the continuous reduction in size, reduction in cost and improvement in performance, the printed circuit board still maintains a strong vitality in the development of future electronic equipment projects. Since the printed circuit board itself is relatively fragile and the number is relatively large, there will be certain risks in the transportation process, so there are special devices for transporting and storing printed circuit boards on the market.

[0003] Utility model patent publication number CN218288753U discloses a circuit board storage rack with support legs, one each for the front, rear, and left sides. Three sets of support rod structures are fixedly connected between the two front transverse support legs, and three sets of fixed longitudinal rods are fixedly connected between the two longitudinal support legs. Three sets of storage structures are fixedly connected to the three sets of fixed longitudinal rods. Upper and lower No. 1 mounting ears are fixedly connected to the inner sides of the two rear transverse support legs. A movable rod is movably connected between the No. 1 mounting ear on the left end and the lower No. 1 mounting ear on the right end via a rotating shaft. A movable rod is movably connected between the No. 1 mounting ear on the left end and the upper No. 1 mounting ear on the right end via a rotating shaft. This utility model circuit board storage rack can be easily folded, stored, and moved, while spacing the circuit boards during storage to prevent damage.

[0004] The prior art still has some problems: 1. Since many printed circuit boards are placed in the storage rack and these printed circuit boards are of different models, it is inconvenient to take them out and they may be taken wrongly due to unclear visibility, which reduces the convenience of operators in taking out the printed circuit boards.

[0005] 2. Since the printed circuit board is relatively thin and its outer surface is coated with a protective layer, if it collides with a threshold or obstacle during movement, it is easy to cause edge collapse or breakage, and it is also easy to scratch the protective layer on its surface.

DETAILED DESCRIPTION

[0031] The present invention will be described in further detail below with reference to the accompanying drawings.

[0032] Combined with attachment Figures 1 to 7 A printed circuit board storage rack mainly includes: a frame body 1, two storage boards 2 arranged one above the other, two telescopic devices 4, a drive assembly, and a shock absorber 7. The frame body 1 is open at the front, and the storage boards 2 are each provided with a plurality of slots 3. The slots 3 separate the printed circuit boards to prevent adjacent printed circuit boards from colliding and damaging the circuits. The slots 3 are used to secure the printed circuit boards. The storage boards 2 are covered with a transparent protective shell (not shown in the figure) to prevent the printed circuit boards from accidentally falling off the storage boards 2 when the frame body 1 is moved.

[0033] Then, the telescopic device 4 includes a screw rod 5 and a threaded block 6. The telescopic device 4 drives the threaded block 6 to extend and retract the storage plate 2 through the rotation of the screw rod 5. A slide groove 9 is opened on the upper and lower parts of one side of the inner wall of the frame 1. The screw rod 5 is arranged in the slide groove 9. The front and rear ends of the screw rod 5 are rotatably connected to the inner wall of the slide groove 9. The threaded block 6 is threadedly connected to the screw rod 5. The upper and lower ends of the threaded block 6 are slidably connected to the inner wall of the slide groove 9. The threaded block 6 is fixedly connected to the rear side of the storage plate 2 near the slide groove 9. The upper and lower parts of the side of the frame 1 away from the slide groove 9 are opened. A slide groove 2 10 is slidably connected in the slide groove 2 10. The rear side of the storage plate 2 near the slide groove 2 10 is fixedly connected to the slide groove 11.

[0034] Specifically, the driving assembly is used to drive the telescopic device 4, and the driving assembly includes a motor 12. The motor 12 is fixedly connected to the rear end of the frame 1. The output shaft of the motor 12 passes through the frame 1 and extends to the upper slide groove 9, and is fixedly connected to the screw rod 5. The front end of the upper screw rod 5 passes through the slide groove 9 and extends to the front thereof, and is fixedly connected to the driving wheel 13. The front end of the lower screw rod 5 passes through the slide groove 9 and extends to the front thereof, and is fixedly connected to the driven wheel 14. The driving wheel 13 and the driven wheel 14 are connected by a synchronous belt 20.

[0035] The upper screw rod 5 is driven to rotate by the motor 12, and the driving wheel 13 rotates accordingly, and the driven wheel 14 is driven to rotate through the synchronous belt 20, driving the lower screw rod 5 to rotate, and then the threaded block 6 slides forward in the slide groove 1 9, driving the storage plate 2 forward, and at the same time the slider 11 slides forward in the slide groove 2 10 until the threaded block 6 moves to the front of the slide groove 1 9, so as to facilitate the removal of the printed circuit board. During the forward movement of the storage plate 2, it will not come into contact with the driving wheel 13, the driven wheel 14 and the synchronous belt 20.

[0036] Next, the shock absorbing device 7 is arranged at the four corners of the lower end of the frame 1. The shock absorbing device 7 includes a moving wheel 8 and a shock absorbing assembly. When the shock absorbing device 7 moves through the moving wheel 8, the shock absorbing assembly performs shock absorption. The shock absorbing assembly includes two fixed plates 15 parallel on both sides. Shock absorbers 16 are provided on the sides of the fixed plates 15 close to each other. The upper ends of the fixed plates 15 and the shock absorbers 16 are fixedly connected to the lower end of the frame 1. The ends of the fixed plates 15 close to each other are provided with three slide grooves 17. The lower ends of the shock absorbers 16 on both sides are fixedly connected to the mounting frames 18. The two sides of the mounting frames 18 are respectively slidably connected to the three slide grooves 17 on both sides. The two sides of the moving wheel 8 are respectively rotatably connected to the surfaces on both sides of the lower part of the mounting frames 18 close to each other. The rear end of the frame 1 is fixedly connected to a push rod 19.

[0037] When the frame 1 is pushed by the push rod 19, the moving wheel 8 moves. When climbing over an obstacle such as a threshold, the moving wheel 8 moves upward, and the mounting frame 18 slides upward in the three slide grooves 17 on both sides to compress the shock absorber 16. After climbing over the obstacle, the shock absorber 16 rebounds, and the mounting frame 18 slides downward in the three slide grooves 17 on both sides, and the moving wheel 8 resets, cushioning the impact force and vibration of the fall to avoid damage to the printed circuit board.
