Description

Technical Field

[0001] This utility model belongs to the technical field of printed circuit board automation equipment, and in particular relates to a multi-layer temporary storage rack for printed circuit board work-in-process. Background Technology

[0002] As electronic products continue to evolve towards high-end and miniaturized designs, the manufacturing process of printed circuit boards (PCBs) is becoming increasingly complex. The temporary storage management of work-in-process (WIP) during production has become a crucial aspect of ensuring smooth production line operation. To meet the demands of intelligent manufacturing for efficient logistics systems, manufacturing enterprises commonly employ automated temporary storage systems to connect upstream and downstream processes. Against this backdrop, automated temporary storage racks, as core equipment, are particularly critical in their design and layout.

[0003] Currently, most mainstream automated temporary storage racks adopt a single-layer structure design. To meet the temporary storage capacity required by the production line, multiple racks arranged in parallel are usually required. The layout of these devices must not only ensure the accessibility and availability of work-in-process, but also guarantee the stability of the production cycle. However, while increasing the number of racks can help improve the overall throughput of the system and alleviate the rhythm differences between upstream and downstream processes, it also leads to an increase in the equipment footprint.

[0004] In terms of factory space planning, while traditional flat-plan layouts are simple in structure and easy to implement, they often occupy a large amount of valuable space and restrict the rational arrangement of other production equipment. Furthermore, material handling paths may become circuitous and intersecting due to an unreasonable layout, leading to additional logistics time losses and consequently affecting the smoothness and operational efficiency of the entire production line. Faced with increasingly scarce factory space resources, how to achieve three-dimensional utilization of space has become a core issue that manufacturing enterprises urgently need to address.

[0005] Currently, the demand for high-end printed circuit boards (PCBs) continues to grow, driving manufacturing enterprises to accelerate the upgrading and transformation of intelligent manufacturing projects. However, the traditional planar layout of temporary storage racks severely restricts the improvement of PCB work-in-process storage density, thereby affecting the market competitiveness and overall efficiency of enterprises. Therefore, optimizing the spatial layout of temporary storage racks and making full use of three-dimensional space to improve storage capacity and efficiency has become a key path to achieving sustainable development of manufacturing systems.

[0006] Therefore, in view of the above situation, there is an urgent need to develop a multi-layer temporary storage rack for printed circuit board work-in-process to overcome the shortcomings in current practical applications. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-layer temporary storage rack for printed circuit boards in process, which aims to solve the problems mentioned in the background art.

[0008] This utility model is implemented as follows: a multi-layer temporary storage rack for printed circuit board work-in-process includes a temporary storage rack body and a lifting and loading device; the temporary storage rack body includes an upper temporary storage unit and a lower temporary storage unit; the lifting and loading device is located on one side of the temporary storage rack body, and its lifting stroke covers the bearing surface height of the upper and lower temporary storage units, for lifting / lowering the printed circuit board work-in-process to the plane of the target temporary storage unit for storage and retrieval.

[0009] In a further technical solution, both the upper and lower temporary storage units include rollers, which are load-bearing structures for carrying printed circuit board products, and the rollers are self-powered or driven by a motor.

[0010] In a further technical solution, the conveying direction of the lifting and unloading device is perpendicular to the rolling direction of the rollers of the upper and lower temporary storage units.

[0011] A further technical solution also includes a laser positioning system, wherein the transmitting end of the laser positioning system is installed on the lifting and unloading material handling device, and the receiving end of the laser positioning system is installed on the temporary storage rack body; when the laser offset of the laser positioning system is <±1mm, an interlocking signal is triggered.

[0012] In a further technical solution, the temporary storage rack body supports a plate frame, a tray, or a TRAY carrier.

[0013] The multi-layer temporary storage rack for printed circuit board work-in-process provided by this utility model has the following beneficial effects: Through the dual-layer structural design and the vertical collaborative operation of the lifting and unloading device, the storage capacity is doubled within the same floor area, greatly improving space utilization and effectively solving the problem of tight factory space.

[0014] This system requires only one inlet / outlet station to flexibly store and retrieve materials between upper and lower temporary storage units, reducing the occupation of logistics channels and lowering the overall footprint and construction costs of the equipment, while maintaining maintenance convenience similar to that of a single-layer temporary storage rack.

[0015] In summary, this temporary storage rack not only improves the overall efficiency and flexibility of the production line, but also features low cost and easy maintenance, providing printed circuit board manufacturers with an efficient and compact work-in-process storage solution with significant application value and economic benefits.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figure 1-2 As shown, an embodiment of this utility model provides a multi-layer temporary storage rack for printed circuit boards in process, comprising an upper temporary storage unit 1 and a lower temporary storage unit 2 forming a rack body. The rack body is designed with two layers (i.e., upper temporary storage unit 1 and lower temporary storage unit 2), and simultaneously supports board frames, trays, and TRAY carriers. The temporary storage position can be selected by the number of carriers. The lifting and unloading device 3 is located on one side of the rack body and is designed as a separate unit for easy transportation and assembly.

[0020] The upper temporary storage unit 1 and the lower temporary storage unit 2 both include rollers for moving and temporarily storing goods. The rollers are load-bearing structures for carrying printed circuit boards in work-in-process, and the rollers are self-powered or driven by a motor.

[0021] The lifting and unloading device 3 has a lifting stroke that covers the bearing surface height of the upper temporary storage unit 1 and the lower temporary storage unit 2, and is used to lift / lower the printed circuit board in-process to the target temporary storage unit plane for storage and retrieval. Its transfer direction is perpendicular to the rolling direction of the rollers of the upper temporary storage unit 1 and the lower temporary storage unit 2.

[0022] Materials are fed in and out through the lifting and unloading device 3, which can be connected to the upper temporary storage unit 1 and the lower temporary storage unit 2 respectively, forming a vertical double-layer printed circuit board work-in-process storage space, thus improving the utilization rate of vertical space.

[0023] Both the lifting and unloading material handling device 3 and the temporary storage rack body are equipped with a laser positioning system. The laser positioning system transmitter is installed on the lifting and unloading material handling device 3, and the laser positioning system receiver is installed on the temporary storage rack body. When the laser offset is <±1mm, an interlocking signal is triggered to ensure the positioning accuracy of the lifting and unloading material handling device 3 and the temporary storage rack body.

[0024] Example: A temporary storage rack operating in Tray vehicle mode.

[0025] The goods are transported by the logistics transport trolley to the lifting and loading device 3 to request transport. After docking with the lifting and loading device 3, the sensors determine whether the upper temporary storage unit 1 and the lower temporary storage unit 2 are empty or full. The goods are then transported to the lower temporary storage unit 2 for temporary storage through the relay of the roller drive between the lifting and loading device 3 and the lower temporary storage unit 2.

[0026] Alternatively, the goods can be transported to the upper temporary storage unit 1 by the longitudinal movement of the lifting and unloading device 3, and then transported to the upper temporary storage unit 1 for temporary storage by the relay of the roller drive of the lifting and unloading device 3 and the upper temporary storage unit 1.

[0027] Furthermore, there are no specific limitations on the control, model, and circuit connection of each component, which can be flexibly configured in practical applications.

[0028] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0029] The present invention provides a multi-layer temporary storage rack for printed circuit board work-in-process in the above embodiments. By adopting a double-layer structure design consisting of an upper temporary storage unit 1 and a lower temporary storage unit 2, combined with the vertical collaborative operation of the lifting and unloading material handling device 3, the storage capacity per unit area is effectively improved, and the space utilization rate is doubled. It solves the bottleneck problem of tight factory space without increasing the ground occupation, and is especially suitable for PCB intelligent manufacturing scenarios with limited space but high requirements for storage capacity.

[0030] The precise docking between the lifting inlet / outlet device 3 and the double-layer temporary storage unit allows for flexible access to both layers of the temporary storage unit with only one inlet / outlet station. This significantly reduces the space required for logistics channels and equipment layout, lowering the overall equipment footprint and construction costs. Simultaneously, while maintaining maintenance convenience similar to traditional single-layer temporary storage racks, this structural design further enhances the system's operational flexibility and adaptability, meeting the temporary storage needs of various printed circuit board products at different production cycles, from high-end to low-end.

[0031] Furthermore, the temporary storage rack is equipped with a laser positioning system to ensure that the positioning accuracy between the lifting and unloading device 3 and the temporary storage unit is controlled within ±1mm, effectively guaranteeing the stability of material handling and the reliability of automated operation, and improving the overall system safety and operational efficiency. The roller conveyor structure can be configured as self-driven or motor-driven according to actual needs, further enhancing the applicability and scalability of the equipment.

[0032] In summary, this utility model has a reasonable structural design, high space utilization, low manufacturing and maintenance costs, and stable and reliable operation. It has good prospects for promotion and application, and provides printed circuit board manufacturers with an efficient and compact work-in-process storage solution in the process of intelligent manufacturing upgrade. It has significant economic benefits and industrial application value.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
