Description

Technical Field

[0001] This utility model relates to the field of circuit board storage technology, specifically to a printed circuit board storage rack. Background Technology

[0002] Printed circuit boards (PCBs) are fundamental components that support and connect electronic components. They are typically made of an insulating substrate with conductive patterns printed on it using processes such as chemical etching. During PCB manufacturing, especially in stages such as surface mount technology (SMT) before soldering, after soldering before testing, after testing before assembly, as well as in rework and turnover scenarios, a large number of PCBs need to be stored in an orderly, safe, and efficient manner. Storage racks are required for this process.

[0003] Existing circuit board storage racks are mostly flat structures with fixed grooves. This type of structure does not have limiting structures at both ends of the circuit boards, which means that the circuit boards may slip out from the openings on both sides during transportation, which may cause damage to the circuit boards and affect their quality. Utility Model Content

[0004] (I) Technical problems to be solved The technical problem to be solved by this utility model is to overcome the defect that the above-mentioned circuit board storage rack does not have a limiting structure, which may cause damage to the circuit board, and to provide a printed circuit board storage rack.

[0006] As an improvement: the bottom surface of the U-shaped frame is provided with two through holes on both sides of the through hole one, and a sliding rod is connected in the through hole two. The bottom surface of the base plate is symmetrically connected with a sliding block two, and the sliding rod is inserted into the sliding block two.

[0007] As an improvement: both tooth block one and tooth block two are unidirectional tooth structures, and the two slide plates are connected by a handle.

[0008] As an improvement: several partitions are snapped onto the inner wall of the limiting plate, and sponge pads are glued to both sides of the partitions. Several L-shaped slots are equally spaced on the inner wall of the limiting plate, and the number of partitions is the same as the number of slots.

[0010] As an improvement: handles are connected to both ends of the U-shaped frame, and anti-static pads are glued to the bottom surface of the U-shaped frame.

[0011] (III) Beneficial Effects The advantages of this utility model compared with the prior art are as follows: 1. The U-shaped frame upper limit component can limit the two ends of the stored circuit board, thereby preventing the circuit board from slipping and being damaged during transportation, and improving the safety of the transfer process; 2.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0019] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0020] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1 and Figure 5 As shown, a printed circuit board storage rack includes a U-shaped frame 1, with handles 21 connected to both ends of the U-shaped frame 1. The handles 21 facilitate the handling of the U-shaped frame 1 after storage. Anti-static pads 22 are glued to the bottom surface of the U-shaped frame 1. Since many circuit boards are sensitive to static electricity, the design of the anti-static pads 22 can isolate some static electricity and protect the safety of the circuit boards. Storage racks are often of fixed dimensions, making it difficult to accommodate circuit boards of various sizes and specifications available on the market. This can lead to improper storage of the circuit boards. Therefore, in conjunction with the attached... Figure 1 , Figure 2 and Figure 5 As shown, the U-shaped frame 1 has a through hole 2, and a bidirectional lead screw 3 is rotatably connected in the through hole 2. A knob is connected to one end of the bidirectional lead screw 3. A symmetrically arranged limiting component is threaded on the bidirectional lead screw 3. The limiting component includes a base plate 4. A limiting plate 5 is provided on the top surface of the base plate 4. A slider 6 is threadedly connected to the bidirectional lead screw 3 on the bottom surface of the base plate 4. Among them, the combination of appendix Figure 5 As shown, the bottom surface of the U-shaped frame 1 is provided with two through holes 12 on both sides of the through hole 1. A sliding rod 13 is connected in the through hole 12. A slider 14 is symmetrically connected to the bottom surface of the base plate 4. The sliding rod 13 is inserted into the slider 14. The sliding rod 13 and the slider 14 cooperate to limit the displacement trajectory of the limiting component. With the above structure, the bidirectional lead screw 3 serves as the main driving component. When the bidirectional lead screw 3 is rotated clockwise, the slider 6 engages with the bidirectional lead screw 3 through a threaded connection, causing the symmetrically arranged limiting components on both sides to move away at the same speed, increasing the distance between the two limiting components and accommodating larger circuit boards. At the same time, when the bidirectional lead screw 3 is rotated counterclockwise, the distance between the two limiting components shortens, allowing for the storage of smaller circuit boards. During this adjustment process, the slide bar 13 guides the limiting plate 5 to slide, allowing only horizontal displacement movement.

[0022] In order to ensure the stability of the position of the limit plate 5 during the adjustment process, combined with the attached... Figures 3 to 5 As shown, the U-shaped frame 1 has symmetrical sliding holes 7 on one side. A slide plate 9 is connected to the sliding hole 7 through a spring 8. Grooves are opened on the front and rear side walls of the sliding hole 7. The spring 8 is connected in the groove and one end of the spring 8 is connected to the protrusion on the slide plate 9. Multiple tooth blocks 10 are equidistantly arranged on the slide plate 9. A tooth block 2 11 that meshes with the tooth block 10 is connected to the side of the limiting plate 5 near the sliding hole 7. Both the tooth block 10 and the tooth block 2 11 are unidirectional tooth structures. This design allows the two to form a mechanical lock, thereby locking the adjusted position and making the limiting plate 5 only unidirectionally adjustable. The two slide plates 9 are connected by a pull handle 15. Spring 8 provides elastic force and is connected between the slide plate 9 and the groove. When the limiting plate 5 slides outward through the above structure, the second tooth block 11 is continuously engaged in the tooth groove formed by the two first tooth blocks 10 under the combined action of its structure and the elastic force of spring 8. When the limiting plate 5 is adjusted to a suitable position, the engagement of the tooth blocks can automatically lock the position to prevent it from sliding, thereby ensuring safety during use. If it is necessary to adjust the spacing of the limiting plate 5, simply pull the handle 15 outward to separate the first tooth block 10 and the second tooth block 11, and then the adjustment can be reversed.

[0023] Since different circuit boards have different thicknesses, in order to further improve the versatility of the storage rack, combined with the attached... Figure 1 and Figure 2 As shown, several partitions 16 are snapped onto the inner wall of the limiting plate 5. Sponge pads 17 are glued to both sides of the partitions 16. Several L-shaped slots 18 are equally spaced on the inner wall of the limiting plate 5. The number of partitions 16 and slots 18 is the same. When in use, the partitions 16 are snapped into the slots 18 at different positions to accommodate circuit boards of different thicknesses and separate adjacent circuit boards. At the same time, the sponge pads 17 provide a soft contact surface, which can buffer the impact on the circuit board during storage or slight vibration, effectively prevent the surface of the circuit board from being scratched or abraded, and protect the circuit board and its components. Combined with appendix Figure 1 and Figure 5 As shown, the top surfaces of the vertical plates on both sides of the U-shaped frame 1 are respectively provided with insert plates 19, and the bottom surface of the U-shaped frame 1 is provided with slots 20 corresponding to the insert plates 19. The insert plates 19 and slots 20 are matched in size. When the height of the stored circuit board is less than the height of the limiting plate 5, multiple U-shaped frames 1 can be stacked vertically to save space. At this time, the insert plate 19 of the lower U-shaped frame 1 is inserted into the slot 20 of the upper U-shaped frame 1 to ensure the stability during placement.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
