Description

Technical Field

[0001] This utility model relates to the field of PCB board packaging and feeding technology, and in particular to a cold-packing vacuum feeding device for PCB board packaging. Background Technology

[0002] After the PCB board is manufactured, it needs to be packaged and shipped to the customer. For customers shipping overseas by sea, the material takes a long time and the packaging requirements are high. Otherwise, it will leak air and absorb moisture, affecting the product performance. Or, if the packaging is not properly protected, the board will be damaged and directly scrapped. Therefore, a vacuum packaging machine is needed to package the PCB board with high quality. The feeding device is used to feed the PCB board to be packaged into the device, and the packaged PCB board inside the device is then fed out by the feeding device.

[0003] In existing PCB packaging equipment, PCBs are vacuum-packed with plastic bags and discharged via conveyor belts. The discharged materials are usually directly piled on the unloading platform. The materials are piled in the same place, resulting in messy stacking. This stacking method requires a large placement area, resulting in low workshop space utilization, especially in mass production environments.

[0004] Therefore, in response to the problem that the PCB packaging equipment described above results in the materials being packed and stacked in the same location, causing messy stacking and occupying a large amount of space, there is an urgent need to design a new type of cold-packing vacuum feeding device for PCB packaging. Utility Model Content

[0005] To overcome the problem that common PCB packaging equipment results in materials being packaged and stacked in one place, causing messy stacking and occupying a large space.

[0006] The technical solution of this utility model is as follows: a cold-packing vacuum feeding device for PCB board packaging, including a vacuum packaging machine and a conveyor belt installed on the left end of the vacuum packaging machine; it also includes a feeding frame set at the left end of the conveyor belt, the lower end of the feeding frame is connected to a base plate through a support rod, a lifting component is installed on the upper end of the base plate, a pushing component is installed on the lifting component, a guide component is set on the outside of the lifting component, and a discharging component is set on the upper end of the base plate. The lifting component is used to control the height of the pushing component, the pushing component is used to push the PCB board into the discharging component, the discharging component is used to temporarily store stacked materials, the guide component has a limiting and guiding effect on the pushing component, a transport module is installed on the inner side of the feeding frame, the transport module is responsible for docking the PCB board with the conveyor belt, and a detection module is installed on the discharging component.

[0007] Preferably, the vacuum packaging machine is used for cold vacuum sealing of PCB boards. The conveyor belt continuously transports the PCB boards from the vacuum packaging machine to the feeding frame, ensuring smooth material flow. The feeding frame, as the supporting frame of the overall feeding structure, carries the transport module and the pushing component, ensuring structural stability. The base plate supports the lifting component and the unloading component, serving as the basic platform of the entire device. The lifting component adjusts the height of the pushing component to match the current height of the material stacking platform, adapting to different stacking requirements. The pushing component pushes the PCB boards transported by the transport module into the unloading component, completing a single feeding action. The guide component provides guidance and limits for the movement of the pushing component, ensuring its smooth operation and accurate positioning. The unloading component receives and temporarily stacks the packaged PCB boards for subsequent centralized transfer. The transport module smoothly transports the PCB boards within the feeding frame and docks with the transport belt. The detection module monitors the stacking status in real time and controls the stacking platform to automatically descend, ensuring neat and orderly stacking.

[0008] Preferably, the lifting assembly includes an electric push rod 1 mounted on the upper end of the base plate, a connecting plate mounted on the output end of the electric push rod 1, two connecting rods connected to the upper end of the connecting plate, and an L-shaped plate disposed on the upper end of the connecting rods. The connecting rods are slidably connected to the feeding frame. The electric push rod 1 is used to control the up and down movement of the L-shaped plate, and the connecting plate and connecting rods are used to transmit the power of the electric push rod 1.

[0009] Preferably, the feeding assembly includes an electric slide rail mounted on the upper end of the L-shaped plate, a sliding block slidably connected to the surface of the electric slide rail, a connecting plate connected to the outer side of the sliding block, and a push plate connected to the end of the connecting plate away from the sliding block. The electric slide rail is used to control the movement of the sliding block, and the movement of the push plate can push the PCB board. The push plate is responsible for pushing the PCB board from the transport module into the feeding assembly.

[0010] Preferably, the guide assembly includes two sliders disposed on the surface of the L-shaped plate away from the push plate. A groove is provided on the inner side wall of the feeding frame at the position corresponding to the slider. The groove and the slider are slidably connected. The groove and the slider provide stability for the push plate to move up and down.

[0011] Preferably, the feeding assembly includes an electric push rod II mounted on the upper end of the base plate, a mounting block mounted on the output end of the electric push rod II, and a detachable material stacking platform mounted on the mounting block. The electric push rod II is used to control the height of the material stacking platform.

[0012] Preferably, the detection module includes a vision detector installed on the material stacking platform. The vision detector is used to determine whether one layer of the material stacking platform is fully stacked. The material stacking platform will automatically descend a certain distance according to the preset height to make room for the next layer.

[0013] Preferably, the transport module includes multiple rotating rollers rotatably mounted inside the feed frame, which provide a smooth and continuous surface for smooth movement.

[0014] The beneficial effects of this utility model are:

[0015] 1. During the stacking process, when a layer of PCB board is pushed into the material stacking platform, the detection module's vision detector identifies the current stacking status and determines whether the layer is fully stacked. If the current layer has been stacked, a lifting command is triggered, controlling the electric push rod two to drive the mounting block and the material stacking platform to descend a certain distance according to the preset height value. This leaves an accurate space for the stacking of the next layer of PCB board, which is beneficial for vertical stacking of PCB boards and avoids messy stacking of packaged PCB boards.

[0016] 2. A slider is set on one side of the L-shaped plate, and a groove is opened at the corresponding position of the feeding frame, so that the slider can slide smoothly in the groove. The guide structure effectively limits the lateral displacement of the pushing component during the lifting process, enhances its running stability in the vertical direction, and avoids mechanical wear or running jam caused by shaking or uneven load.

The feeding frame 3 serves as the supporting frame of the overall feeding structure, bearing the transport module and the pushing component, ensuring structural stability. The base plate 4 supports the lifting component and the unloading component, serving as the basic platform for the entire device. The lifting component is used to adjust the height of the pushing component to match the current height of the material stacking platform 18, adapting to different stacking requirements. The pushing component is responsible for pushing the PCB boards conveyed by the transport module into the unloading component, completing a single feeding action. The guide component provides guidance and limits for the movement of the pushing component, ensuring its smooth operation and accurate positioning.

[0025] Please see Figures 1-4In this embodiment, the lifting assembly includes an electric push rod 5 mounted on the upper end of the base plate 4, a connecting plate 6 mounted on the output end of the electric push rod 5, two connecting rods 7 connected to the upper end of the connecting plate 6, and an L-shaped plate 8 set on the upper end of the connecting rods 7. The connecting rods 7 are slidably connected to the feeding frame 3. The electric push rod 5 is used to control the up and down movement of the L-shaped plate 8. The connecting plate 6 and the connecting rods 7 are used to transmit the power of the electric push rod 5 (the electric push rod 5 provides lifting power to control the overall height adjustment of the pushing assembly; the connecting plate 6 connects the electric push rod and the connecting rods 7 to transmit the lifting action; the connecting rods 7 support the L-shaped plate 8, assist in power transmission, and maintain the stability of the structure; the L-shaped plate 8 serves as the mounting base of the pushing assembly and moves up and down with the lifting assembly). The pushing assembly includes an electric slide rail 11 mounted on the upper end of the L-shaped plate 8, a sliding block 12 slidably connected to the surface of the electric slide rail 11, a connecting plate 13 connected to the outer side of the sliding block 12, and a push plate 14 connected to the end of the connecting plate 13 away from the sliding block 12. The electric slide rail 11... The sliding block 12 is used to control the movement of the sliding block 12. The push plate 14 can push the PCB board. The push plate 14 is responsible for pushing the PCB board from the transport module to the unloading assembly. (The electric slide rail 11 drives the sliding block 12 to move along the track, realizing the back and forth movement of the push plate 14. The sliding block 12 slides on the electric slide rail 11, driving the connecting plate 13 and the push plate 14 to move together. The connecting plate 13 connects the sliding block 12 and the push plate 14 to transmit the pushing power. The push plate 14 directly contacts the PCB board and pushes the material from the transport module to the unloading assembly.) The guide assembly includes two sliders 10 set on the surface of the L-shaped plate 8 away from the push plate 14. The inner side wall of the feeding frame 3 is provided with a groove 9 at the position corresponding to the slider 10. The groove 9 and the slider 10 are slidably connected. The groove 9 and the slider 10 provide a guarantee for the stability of the push plate 14 moving up and down. (The slider 10 is installed on the L-shaped plate 8 and moves with it for guidance and limitation. The groove 9 is fixed inside the feeding frame 3 and cooperates with the slider 10 to limit the offset of the pushing assembly and enhance the running stability.)

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5In this embodiment, the feeding assembly includes an electric push rod 16 mounted on the upper end of the base plate 4, a mounting block 17 mounted on the output end of the electric push rod 16, and a detachable material stacking platform 18 mounted on the mounting block 17. The electric push rod 16 is used to control the height of the material stacking platform 18 (the electric push rod 16 provides lifting power to control the height change of the material stacking platform 18; the mounting block 17 connects the electric push rod and the material stacking platform 18 to transmit the lifting action; the material stacking platform 18 is used to receive and neatly stack packaged PCB boards; after the material stacking platform 18 is full, it can be disassembled or replaced to accommodate materials of different specifications). The detection module includes a... A vision detector 19 is installed on the material stacking platform 18. The vision detector 19 is used to determine whether one layer of the material stacking platform 18 is fully stacked. The material stacking platform 18 will automatically descend a certain distance according to the preset height to make room for the next layer (the vision detector 19 identifies the stacking status, determines whether the current layer is fully stacked, triggers the stacking platform descent command, and realizes stacking control). The transport module includes a rotating roller 15 rotatably installed inside the feeding frame 3. Multiple rotating rollers 15 are provided. The rotating rollers 15 provide a smooth and continuous surface for smooth movement (the rotating rollers 15 provide a smooth and continuous transport path for the PCB board, allowing it to smoothly enter the stacking area).

[0027] During operation, the PCB board undergoes cold vacuum sealing in the vacuum packaging machine 1 to prevent moisture and oxidation, thus improving packaging quality. The packaged PCB board is then conveyed to the left by the conveyor belt 2 and enters the feeding frame 3 area, preparing for subsequent stacking. The PCB board enters the transport module, where a conveyor path composed of multiple rotating rollers 15 smoothly transports it, ensuring the material smoothly enters the pushing area. Based on the current stacking height, the lifting component drives the connecting plate 6 and connecting rod 7 via the electric push rod 5, causing the L-shaped plate 8 to move up and down, maintaining a height match between the pushing component and the stacking table. The electric slide rail 11 drives the sliding block 12 to move, via the connecting... The plate 13 drives the pusher plate 14 forward, pushing the PCB board from the transport module into the unloading assembly. The slider 10 cooperates with the slide 9 to provide guidance and limit for the unloading assembly, preventing deviation or shaking during the unloading process and ensuring smooth and accurate unloading action. The PCB board is pushed into the unloading assembly and received by the material stacking platform 18 for temporary stacking. The stacking platform is installed on the mounting block 17 and its height can be adjusted up and down with the electric push rod 16. The vision detector 19 detects the stacking status in real time. When it is determined that the current layer is full, the command is automatically triggered to control the electric push rod 16 to drive the material stacking platform 18 to descend to a preset height to make room for the next layer.

[0028] Through the above steps, during the stacking process, after the PCB board is pushed into the material stacking platform 18, the vision detector 19 identifies the stacking status. After determining that the current layer is full, it triggers a command to control the electric push rod 16 to drive the stacking platform to descend at a preset height, reserving space for the next layer, thus achieving vertical and orderly stacking and avoiding messy stacking. This solves the problem of common PCB board packaging equipment where the packaged materials are concentrated in the same position, resulting in messy stacking and occupying a large amount of space.
