Description

Technical Field

[0001] This utility model relates to the field of PCB pallet storage technology, and in particular to an automated storage and retrieval system for PCB lamination processes. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), the storage of semi-finished boards is a crucial link connecting various processes (such as etching, drilling, and solder mask treatment). Due to the characteristics of PCB semi-finished boards being thin, easily scratched, and prone to edge damage, in order to avoid problems such as board deformation, surface contamination, or damage to electrical performance during storage and transportation, the industry generally uses special storage trays to store semi-finished boards. Single or multiple boards are embedded into the limiting slots of the tray at preset intervals, and the independent isolation of the boards is achieved through the structural protection of the tray. In the existing technology, the storage operation after the board material is loaded onto the pallet mainly relies on manual operation. The specific process is as follows: the operator manually moves the pallet containing the PCB semi-finished board material (the weight of a single pallet containing the board material is usually 30KG-80KG). According to the production plan or the distribution of empty spaces on the storage rack, the pallets are placed one by one on the designated shelf of the storage rack. When the board material needs to be retrieved in the subsequent process, the corresponding pallet is then manually removed from the storage rack and transferred to the processing station. However, the above-mentioned manual storage method has the following significant drawbacks in practical applications: High labor intensity: The shelf height of the storage rack is usually 0.5-2.0m. Operators need to repeatedly bend over to pick up pallets, stand up to move them, lift and place them in position. Long-term operation can easily lead to occupational health problems such as lower back muscle strain and joint damage. Especially in mass production scenarios, hundreds of pallets need to be processed every day, and the manual labor load is extremely high. Low storage efficiency: A single manual pallet handling and placement operation takes about 15-30 seconds, and the efficiency is greatly affected by the operator's physical condition and skill level, making it difficult to meet the cycle time requirements of continuous multi-process production in the PCB manufacturing industry. At the same time, problems such as pallet misalignment and uneven utilization of shelf space are prone to occur during manual placement, requiring additional time for adjustment, which further reduces storage efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The present invention relates to an automated storage and retrieval system for PCB lamination processes, comprising a storage warehouse; the storage warehouse includes a fixed frame and storage trays evenly arranged along the fixed frame. Lifting devices are installed on both sides of the storage warehouse; the lifting device includes a lift and an outer frame; a material tray assembly is slidably connected to the outer frame; one end of the lift is fixed to the outer frame; the other end of the lift is fixed to the material tray assembly; the storage rack is a first conveyor line; a second conveyor line is installed on the material tray assembly.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figures 1 to 6 As shown, the present invention provides an automated storage and retrieval system for PCB lamination processes, comprising a storage warehouse 2; the storage warehouse 2 includes a fixed frame 203 and storage trays evenly arranged along the fixed frame 203. Lifting devices 1 are provided on both sides of the storage warehouse 2; each lifting device 1 includes a lifting machine 103 and an outer frame 102; a material tray assembly 3 is slidably connected to the outer frame 102; one end of the lifting machine 103 is fixed to the outer frame 102; the other end of the lifting machine 103 is fixed to the material tray assembly 3; the storage bracket is a first conveyor line 201; a second conveyor line 303 is provided on the material tray assembly 3; The second conveyor line 303 and the first conveyor line 201 are essentially no different from the existing roller conveyor lines, so they will not be described in detail. The elevator 103 consists of a motor, a drive sprocket, a driven sprocket and a transmission chain. The motor is connected to the drive sprocket, the transmission chain is tensioned between the drive sprocket and the driven sprocket, and the chain body of the transmission chain is fixed on the material tray assembly 3. The material tray 4 is clamped and fixed on the second conveyor line 303 by the material tray assembly 3. Then, the elevator 103 drives the second conveyor line 303 and the material tray 4 to rise to the height of the first conveyor line 201 where the material is to be stored. The second conveyor line 303 and the first conveyor line 201 work together to send the material tray 4 into the first conveyor line 201 at the set height. The positioning mechanism on the frame 203 fixes the material tray 4 on the first conveyor line 201. When the material tray 4 is needed, the elevator 103 on the other side drives the second conveyor line 303 to connect with the first conveyor line 201 on the same level. Then, the second conveyor line 303 works together with the first conveyor line 201 to send the material tray 4 from the first conveyor line 201 onto the second conveyor line 303. The elevator 103 transports the material tray 4 and the second conveyor line 303 to a position at the same height as the next workstation assembly line and connects with the assembly line. Then, the second conveyor line 303 sends the material tray 4 onto the assembly line. The loading is completed.

[0016] This structure enables automatic loading and unloading of material trays, reducing labor intensity and improving storage efficiency.

[0017] In a preferred embodiment of this utility model, the number of storage bins 2 is at least two; the storage bins 2 are arranged sequentially between two lifting devices 1; the material trays 4 are conveyed between adjacent first conveyor lines 201 at the same height; one lifting device 1 is for feeding and the other lifting device 1 is for discharging, thus creating a continuous flow of new materials.

[0018] In a preferred embodiment of this utility model, a first telescopic blocking member is provided at both the front and rear ends of the first conveyor line 201; the first telescopic blocking member includes a first stop cylinder 202 and a first stop block connected to the first stop cylinder 202; when the material tray 4 is conveyed between the first conveyor lines 201 or between the first conveyor line 201 and the second conveyor line 303, the first stop cylinder 202 lowers the first stop block to a position that does not obstruct the movement of the material tray 4; When the material tray 4 needs to be positioned on the first conveyor line 201, the first stop cylinder 202 drives the first stop block to rise to a position directly opposite the material tray 4, so that the material tray 4 cannot slide out of the first conveyor line 201.

[0019] In a preferred embodiment of this utility model, multiple photoelectric switches 101 are evenly distributed on the outer frame 102; the number of photoelectric switches 101 is the same as the number of layers of the storage tray on the storage bin 2; when the storage tray has a storage requirement, when the loading tray assembly 3 rises to the position of the photoelectric switch, the corresponding photoelectric switch 101 generates a signal, causing the loading tray assembly 3 to stop rising, and the material tray 4 on the second conveyor line 303 is input into the storage tray at that height. The photoelectric switch 101 is used to assist in positioning, reducing the problem of inaccurate conveying height caused by chain stretching and other deviations during long-term use.

[0020] As a preferred embodiment of this utility model, a pneumatic clamp 306 is fixed on the material tray assembly 3.

[0021] The pneumatic clamp 306 is not fundamentally different from existing technology, so it will not be described in detail. When an abnormal malfunction occurs and the material tray assembly 3 falls out of control and quickly passes through the two photoelectric switches 101, the pneumatic clamp 306 will be triggered for braking protection. The pneumatic clamp 306 will clamp and fix itself on the guide rail of the outer frame 102 to stop and prevent it from falling and being damaged.

[0022] In a preferred embodiment of this utility model, the material tray assembly 3 further includes a bottom support 305; the bottom support 305 is provided with second telescopic blocking members at both ends of the second conveyor line 303; the support of the second conveyor line 303 is fixedly connected to the bottom support 305; the bottom support 305 is fixedly connected to the elevator 103; and the bottom support 305 is provided with side baffles 304 on both sides of the second conveyor line 303. The side baffle 304 is used to limit the material tray 4 in the conveying direction perpendicular to the second conveyor line 303; after the material tray 4 enters the second conveyor line 303, the second telescopic blocking member extends to prevent the material tray 4 from sliding out from both ends of the second conveyor line 303; the elevator 103 drives the bottom support 305, the second conveyor line 303 and the material tray 4 to make conveying movements together.

[0023] As a preferred embodiment of the present invention, the second telescopic blocking member consists of a second stop cylinder 301 with one end fixed on the bottom bracket 305 and a positioning block 302 fixed at the other end of the second stop cylinder 301. The second stop cylinder 301 drives the positioning block 302 to extend and retract.

[0024] As a preferred embodiment of the present invention, both the inner surface and the end face of the side baffle 304 are provided with chamfered surfaces 30401; the chamfered surfaces 30401 are used to guide the material tray 4 into the tray.

[0025] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
