Description

Technical Field

[0001] This utility model relates to the field of PCBA board storage, specifically a PCBA board storage bracket. Background Technology

[0002] In the electronics manufacturing industry, PCBA boards, as the carriers of core electronic components, not only densely contain precision electronic components and complex circuits, making them susceptible to damage from external factors, but also require frequent transfer between different processes. Operators need to quickly and accurately retrieve PCBA boards of specific specifications while ensuring that inconvenient access during storage does not lead to board damage or process delays. Especially in large-scale production scenarios, efficient storage and retrieval operations are directly related to the continuity and efficiency of the production line. Therefore, a PCBA board storage rack with a convenient storage and retrieval structure, enabling rapid retrieval and orderly return, while also meeting dustproof requirements, has become a key piece of equipment for optimizing production management and ensuring product quality. Traditional PCBA board storage technologies have significant shortcomings in terms of ease of access and overall performance, severely restricting production efficiency, product yield, and management convenience. Regarding accessibility, traditional storage racks mostly employ fixed structures, lacking adjustable access channels. Operators must spend considerable time searching for PCBA boards, sometimes even disassembling parts of the structure to retrieve the target board, leading to extended production line waiting times. This is especially problematic in multi-batch, small-volume production, where frequent inefficient access significantly increases production cycles. Furthermore, their unreasonable opening design and internal space planning easily result in disordered PCBA board stacking and limited access angles, increasing the risk of board collision damage and potentially causing electronic components to fall off or circuits to be scratched due to improper force during access, affecting product yield. In addition, traditional storage racks have weak dustproof capabilities; due to inadequate measures, dust accumulation can cause PCBA boards to degrade in performance or even fail, increasing production costs and maintenance workload. Therefore, we propose a new PCBA board storage rack. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a PCBA board storage bracket, which solves the aforementioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a PCBA board storage bracket, comprising: The box-shaped structure is hollow inside and has no top. The clamping device is located inside the box near the bottom. The clamping device includes a base, a fixed padless clamping plate, multiple sets of fixed clamping plates and an elastic clamping structure. The base is fixed with an integrated fixed padless clamping plate and five sets of fixed clamping plates. The fixed padless clamping plate is located at one end of the top of the base and is distributed horizontally at equal intervals with the fixed clamping plates. In addition to the fixed padless clamping plate, each set of fixed clamping plates has an elastic clamping structure on one side for storing PCBA boards. Two sets of symmetrical box covers are set at the top of the box to seal the top of the box. There are connecting rod assemblies between the two sets of box covers and the two ends of the clamping device, and the connecting rod assemblies between the two sets of box covers and the clamping device are symmetrically distributed.

[0005] Preferably, the front and rear walls of the box are fixed with symmetrical anti-slip plates and two sets of box holes, and the bottom outer wall of the box is fixed with four anti-slip pads located at the four bottom corners.

[0006] Preferably, the linkage assembly includes a long connecting rod, a rotating shaft, a connecting rod, and a short connecting rod. The rotating shaft rotates through the holes in the housing. One end of the rotating shaft is fixedly connected to one end of the long connecting rod and is attached to the outside of the housing. The other end of the long connecting rod is rotatably connected to both sides of the housing cover. The other end of the rotating shaft is fixedly connected to one end of the connecting rod, which is located inside the housing. The long connecting rod and the connecting rod form a 40° angle. The other end of the connecting rod is rotatably connected to one end of the short connecting rod, which is located inside the housing.

[0007] Preferably, symmetrically distributed columns are fixed on both sides of the base, and the other end of the short connecting rod is sleeved on the column and rotates to engage with it.

[0008] Preferably, the fixed padless clamp and the fixed clamp on the base are at the same height, and the fixed padless clamp and multiple sets of fixed clamps are distributed horizontally at equal intervals. Two sets of parallel and spaced cylindrical rails are fixedly connected between the fixed padless clamp and the fixed clamp on the other side of the base. The two sets of cylindrical rails are close to the bottom of the fixed padless clamp and the fixed clamp and are distributed on both sides of the square rail. The cylindrical rails pass through the other sets of fixed clamps in sequence.

[0009] Preferably, the elastic structure includes a movable clamping plate and springs. The movable clamping plate slides and engages with the cylindrical rail through symmetrical sliding holes at its bottom end. Multiple sets of springs are sleeved on the cylindrical rail, and the two ends of the springs are respectively in close contact with the back of the fixed clamping plate and the movable clamping plate. A square rail is provided at the top of the base, extending through both ends, and the square rail is located at the bottom end of the fixed clamping plate and the fixed padless clamping plate. The bottom end of the movable clamping plate slides in contact with the square rail.

[0010] Preferably, soft pads are fixedly installed on the sides of the fixed clamp and the movable clamp that are close to each other, and the soft pads on the fixed clamp and the movable clamp are in contact with each other.

[0011] Compared with the prior art, the present invention provides a PCBA board storage bracket, which has the following advantages: I. Significantly improves PCBA board access efficiency and convenience This device effectively enables rapid storage of PCBA boards by raising the storage platform when the cover is opened and lowering it when the cover is closed, completely eliminating the time-consuming searching problem caused by the traditional fixed storage box structure. Operators simply need to open the cover, and the storage platform automatically moves up to a height for easy access, eliminating the need to search deep inside the box and quickly locating and retrieving the target PCBA board. After storage, closing the cover automatically lowers the storage platform back into place. The entire process is convenient and smooth, effectively shortening production line waiting time in multi-batch, small-volume production scenarios and significantly improving the continuity and efficiency of the production process. II. Optimize space utilization and enhance protective performance Compared to traditional storage boxes that suffer from poor space planning and weak protection, this device achieves efficient use of internal space through an automatic lifting and lowering design of the storage platform as the cover opens and closes. Furthermore, after the cover is closed, the storage platform lowers and returns to its original position, placing the PCBA boards in a more stable and protected space. Combined with the closed cover, this effectively prevents dust accumulation and moisture intrusion from affecting the electrical performance of the PCBA boards, reducing the risk of damage during storage, ensuring product quality stability, and reducing production costs and maintenance workload. III. Achieving orderly management and security protection for access operations This device overcomes the limitations of traditional storage box structures with their illogical planning. Utilizing a lifting and adjustable partition design of the storage platform, it achieves orderly storage of PCBA boards. When the cover is opened, the storage platform precisely moves upward to the designated position, facilitating quick retrieval and access by operators. When the cover is closed, the storage platform moves downward back to its original position. This not only prevents errors in storage or loss of PCBA boards due to accidental collisions or misoperation, but also creates a more secure protective space through the closed cover. It solves a series of problems caused by chaotic storage and insufficient protection in traditional technologies, simplifying production management processes and improving management efficiency and safety.

[0018] Furthermore, symmetrically distributed columns 20 are fixed on both sides of the base 12, and the other end of the short connecting rod 11 is sleeved on the column 20 and rotates to engage with it.

[0019] Furthermore, the fixed padless clamping plate 21 and the fixed clamping plate 13 on the base 12 are at the same height, and the fixed padless clamping plate 21 and multiple sets of fixed clamping plates 13 are distributed laterally at equal intervals.

[0022] Structural Description: Box 1: A hollow, topless box-type structure with anti-slip plates and perforations on the front and rear walls, and anti-slip pads at the four corners of the bottom. It is used to house components such as clamping devices, providing installation space and protection; the anti-slip design on the bottom enhances stability.

[0023] Box Cover 2: Two sets are symmetrically arranged at the top of the box and connected to the clamping plate device via a connecting rod assembly. They can seal the top of the box to prevent dust and moisture from entering, and work with the connecting rod assembly to raise and lower the clamping plate device.

[0024] Linkage assembly 3: Composed of a long connecting rod, a rotating shaft, a connecting rod, and a short connecting rod. The rotating shaft is rotatably connected to the box body hole. By rotating each connecting rod, the clamping plate device is raised and lowered when the box cover is opened / closed, improving storage and retrieval efficiency.

[0025] Clamping device 4: Located inside the bottom of the cabinet, it consists of a base, a fixed clamping plate, and a movable clamping plate, and includes an elastic clamping structure. A spring pushes the movable clamping plate to engage with the fixed clamping plate, flexibly clamping the PCBA boards for orderly storage.

[0026] Anti-slip plate 5: Symmetrically fixed to the front and rear walls of the box, increasing friction. This facilitates gripping during handling, prevents the box from sliding, and improves operational safety.

[0027] Anti-slip washers 6: Four washers are located at the four corners of the bottom of the cabinet. They increase the friction between the cabinet and the surface it is placed on, prevent the support from sliding, and ensure stable storage.

[0028] Handle 7: Installed on the top of the cabinet cover. Allows operators to easily pull or push the cabinet cover to open and close the cabinet.

[0029] Long connecting rod 8: One end is fixed to the outside of the housing with the rotating shaft, and the other end is rotatably connected to the housing cover. It transmits the motion of the rotating shaft and drives the housing cover to rotate, and is a key transmission component of the connecting rod assembly.

[0030] Rotating shaft 9: Rotatably connected to the housing bore, with a long connecting rod and a connecting rod at each end. It serves as the rotation center of the linkage assembly, enabling the transmission of internal and external motion.

[0031] Connecting rod 10: One end is fixed inside the housing to the rotating shaft, and the other end is rotatably connected to the short connecting rod. It forms a 40° angle with the long connecting rod and transmits the movement of the rotating shaft to the short connecting rod.

[0032] Short connecting rod 11: One end is rotatably connected to the connecting rod, and the other end is rotatably connected to the columns on both sides of the base. Located inside the housing, it pushes the base to rise and fall, thereby moving the clamping plate device.

[0033] Base 12: The basic component of the clamping device, with columns fixed on both sides and a square rail on top. It supports the fixed clamping plate, the movable clamping plate, etc., and connects with the short connecting rod to achieve lifting.

[0034] Fixed clamping plate 13: Fixed to the base, evenly distributed horizontally, with a soft pad on one side. It works in conjunction with the movable clamping plate to hold the PCBA board.

[0035] Cylindrical rail 14: Two sets of parallel through-type fixed clamping plates and fixed padless clamping plates at their lower ends. This provides a sliding track for the moving clamping plates, ensuring their stability during movement.

[0036] Movable clamping plate 15: Corresponding to the fixed clamping plate, it has a sliding hole in the middle to cooperate with the cylindrical rail, and the bottom fits into the square rail. It is pushed by a spring to fit against the fixed clamping plate, adaptively clamping PCBA boards of different thicknesses.

[0037] Pad 16: Attached to the contact side of the fixed clamp and the movable clamp. It cushions pressure during clamping, preventing hard damage to the PCBA board and protecting the board surface and circuitry.

[0038] Sliding hole 17: drilled in the middle of the movable clamping plate, slidingly engaging with the cylindrical rail. This allows the movable clamping plate to slide stably along the cylindrical rail, enabling adjustment of the clamping force.

[0039] Square rail 18: Located at the top of the base, it fits into the bottom of the movable clamping plate. It assists in guiding the sliding of the movable clamping plate and enhances its stability during movement.

[0040] Spring 19: Sleeves onto the surface of the cylindrical rail and passes through the movable clamping plate. Provides thrust to bring the movable clamping plate into contact with the fixed clamping plate, achieving elastic clamping and adapting to different plate thicknesses.

[0041] Column 20: Symmetrically fixed on both sides of the base, and rotatably connected to the short connecting rod. Serving as the connection point between the connecting rod assembly and the clamping plate device, it transmits the motion of the short connecting rod.

[0042] Fixed padless clamping plate 21: Located at one end of the top of the base, it is equidistant from the fixed clamping plate laterally. It is used to clamp PCBA boards in specific locations and works with the fixed clamping plate to achieve partitioned storage.

[0043] Box body hole 22: Two sets are symmetrically distributed on the front and rear walls of the box body, and are rotatably connected to the rotating shaft. They fit the rotating shaft, provide installation space for the rotating shaft, and ensure the normal rotation of the connecting rod assembly.

[0044] Working principle: When PCBA boards need to be accessed, pull the handle 7 on the enclosure cover 2, and the two symmetrical enclosure covers 2 will move to the sides to open. At this time, the long connecting rod 8, which is rotatably connected to both sides of the enclosure cover 2, moves accordingly, driving the rotating shaft 9, which is fixed in the enclosure hole 22, to rotate. The connecting rod 10, which is connected to the other end of the rotating shaft 9, pushes the short connecting rod 11 at a 40° angle. The short connecting rod 11 is then rotatably connected to the columns 20 on both sides of the base 12, thereby driving the entire clamping device 4 to move upward from the bottom of the enclosure 1 until it rises to a position near the top inside the enclosure 1, making it easy for the operator to directly access the PCBA boards.

[0045] During the upward movement of the clamping device 4, the square rail 18 at the top of the base 12 guides the sliding of the movable clamping plate 15. The sliding hole 17 in the middle of the movable clamping plate 15 slides into contact with the cylindrical rail 14 at the lower end of the fixed clamping plate 13 and the fixed padless clamping plate 21. At this time, the spring 19 passing through the cylindrical rail 14 is compressed, pushing the movable clamping plate 15 away from the fixed clamping plate 13, creating a sufficient gap for the operator to insert the PCBA board between the fixed clamping plate 13 and the movable clamping plate 15. After insertion, the elastic force of the spring 19 flexibly clamps the PCBA board through the soft pad 16 on the movable clamping plate 15, preventing hard damage.

[0046] After the storage and retrieval operation is completed, close the cabinet cover 2. The long connecting rod 8 pulls the rotating shaft 9 in the opposite direction, causing the connecting rod 10 and the short connecting rod 11 to lower the clamping plate device 4 to the bottom of the cabinet 1. At this time, the cabinet cover 2 completely seals the top of the cabinet 1, forming a stable enclosed space with the anti-slip plates 5 on the front and rear walls of the cabinet 1 and the anti-slip pads 6 on the bottom, effectively preventing dust and moisture. At the same time, after the clamping plate device 4 moves down, the PCBA board is fixed inside the cabinet 1, preventing displacement or damage due to external collisions.

[0047] Throughout the process, the long connecting rod 8, rotating shaft 9, connecting rod 10, and short connecting rod 11 of the linkage assembly 3, through precise angle design (the long connecting rod 8 and connecting rod 10 form a 40° angle), achieve the linkage between the opening and closing of the cabinet cover 2 and the lifting and lowering of the clamping device 4. This eliminates the need for manual adjustment of the clamping plate position, significantly improving storage and retrieval efficiency. The spring 19 and soft pad 16 in the clamping device 4 ensure that PCBA boards of different thicknesses can be adaptively clamped, guaranteeing both fixation and preventing damage to the boards. The topless box structure of the cabinet 1 and the closed design of the cabinet cover 2, combined with the linkage lifting and lowering of the linkage assembly 3, achieve efficient space utilization—when opened, the clamping device 4 moves upward to expand the operating space, and when closed, it moves downward to compress the internal space, reducing the risk of dust and moisture intrusion. In addition, the anti-slip plate 5 and anti-slip pad 6 enhance the stability of the bracket during handling and storage, preventing damage to components due to sliding, ultimately achieving a comprehensive effect of convenient storage and retrieval, reliable protection, and optimized space.
