Description

Technical Field

[0001] The present invention relates to the field of PCB board manufacturing equipment, and more specifically to a fully automatic packaging machine for 5G communication PCB boards. Background Art

[0002] PCBs are core components of modern electronic products, and their functionality and performance directly impact product quality and reliability. Therefore, to protect their surfaces from mechanical damage and chemical reactions like oxidation, PCBs must be packaged. This protects the boards from environmental factors, static electricity, physical damage, and other factors, ensuring their integrity and reliability. PCB packaging requires vacuuming to remove gases and moisture from the packaging, thereby preventing oxidation, cracking, and corrosion caused by moisture absorption. Vacuuming also enhances the package's seal, preventing dust and contamination. Furthermore, vacuuming the PCB packaging reduces the board's volume and weight, facilitating storage and transportation.

[0003] Although PCB packaging machines have been widely used and have made great progress, with the increasing quality requirements of core components of modern electronic products, there are many problems with the functions of existing PCB packaging machines in actual applications. The main problems are as follows:

[0004] 1. Most existing packaging machines use plastic rolls to make different types of bags for different types of PCB boards, and then package the PCB boards. This will result in high packaging costs and is not conducive to improving production efficiency;

[0005] 2. Some packaging machines have made some improvements based on this, such as using two pieces of plastic roll film to package PCB boards. Although this saves some costs, the two-piece plastic roll film needs to be packaged on four sides, which has more processes and is not conducive to improving production efficiency.

[0006] 3. Generally, the packaging bag will only be sealed once after vacuuming, which may cause air leakage in the later stage, which is not conducive to the storage and transportation of PCB boards;

[0007] 4. Most existing packaging machines do not inspect the seals of PCB packaging bags, which may result in substandard seals, damage to the packaging bags, air leakage, etc., which is not conducive to the storage and transportation of PCB boards.

[0008] Therefore, the packaging machine must be improved. The present invention adopts a special frame to fold a piece of plastic film in half to reduce the number of edge sealing times, adopts a vacuum secondary sealing machine to ensure the sealing of the PCB board packaging bag after vacuum extraction, and uses a camera to detect the sealing point to avoid the phenomenon of substandard sealing. Summary of the Invention

[0009] The present invention addresses the problem of sealing plastic film during PCB packaging. A special frame is used to fold a piece of plastic film in half. After folding, only the two sides of the plastic film need to be sealed, which is beneficial to saving costs and improving packaging efficiency. A vacuum secondary sealing machine is used to vacuum extract and seal the packaging bag. After the primary sealing is completed, a fan dissipates heat from the sealed part of the packaging bag. After the heat dissipation is completed, a secondary sealing is performed, which is beneficial to reducing air leakage in the packaging bag in the later stage, ensuring the sealing effect, preventing the PCB board from being contaminated, and facilitating storage and transportation. A camera is used to detect the sealing of the packaging bag to avoid the phenomenon of substandard sealing.

[0010] To achieve the above object, the present invention is implemented through the following technical solutions:

[0014] Furthermore, the triangular frame is an acute triangle, the vertex of which is located directly above the middle of the third roller and the fourth roller, and the side opposite to the vertex is welded to the frame and is parallel to the first roller and the second roller;

[0015] Furthermore, the vacuum secondary sealing machine includes a detection device, a vacuum sealing device and an operating table. The detection device includes a pressing plate, a telescopic device and a camera. The pressing plate is fixed to the telescopic device. The detection device is fixed to the outside of the third slide rail of the vacuum secondary sealing machine.

The sealing device is arranged on the second slide rail and moves up and down through the second slide rail. The second slide rail is parallel to the third slide rail. The operating table and the vacuum pump are both arranged on the top of the vacuum secondary sealing machine.

[0016] Furthermore, the pushing device 1 includes a telescopic rod and a pushing plate, the telescopic rod is fixed to the pushing plate, and the telescopic rod 1 is fixed to the stand;

[0017] Furthermore, the heat sealing machine includes a hydraulic device, a lifting plate and a sealing device, the hydraulic device includes a hydraulic pump and a telescopic rod, the hydraulic pump is arranged at the top of the heat sealing machine, the telescopic rod is arranged in the middle of the heat sealing machine, and the two ends are respectively connected to the hydraulic pump and the sealing plate, the heat sealing device includes a heating device and a sealing plate, and the heating device is arranged at the top of the heat sealing machine;

[0018] Furthermore, the lifting plate is fixed to the flat plate where the sealing device 1 is located, and the lifting plate and the sealing device 1 are controlled to rise and fall together by a hydraulic pump;

[0019] Furthermore, the packaging method of the 5G communication PCB board fully automatic packaging machine is characterized in that: when performing the packaging operation, its working procedure can be divided into a plastic film folding process, a PCB board pushing process and a PCB board packaging process, and the steps are as follows:

[0020] S1, the process of folding the plastic film in half, specifically includes the following steps:

[0021] S11, place the bubble plastic roll between the baffle and the first roller, pull one end of the plastic roll to pass through the first roller and the second roller, continue to pull the plastic roll to pass through the triangular frame, the center of the plastic roll passes through the top corner of the triangular frame, and then fold the plastic roll in half and pass it through the gap between the third roller and the fourth roller, pass it from the bottom of the fourth roller and pull it onto the workbench, so that the one-piece plastic roll film is folded in half into two pieces, the upper piece of the plastic roll film passes through the top of the pushing device 1, and the other piece passes from the bottom of the pushing device 1, and the plastic film that passes through the top of the pushing device 1 continues to pass through the top of the lifting plate, and then the upper and lower pieces of the plastic roll film are combined and passed through the gap under the sealing plate of the heat sealer, and then continue to be conveyed forward by the conveyor belt 2. After the one-piece plastic roll film is folded in half, only two sides need to be sealed;

[0022] S2, the process of pushing the PCB board, specifically includes the following steps:

[0023] S21, the pushing device 2 pushes the PCB board onto the workbench, and the PCB board is placed on the conveyor belt 1. The conveying direction of the PCB board is opposite to the forward direction of the plastic film, and the packaging is ready;

[0024] S3, PCB board packaging process, specifically including the following steps:

[0025] S31. Pushing device 1 pushes the PCB on the workbench to the heat sealer. After the PCB is transported to the designated position, it stops. Pushing plate 2 on pushing device 2 slides on slide rail 3 to push the PCB from conveyor belt 1 to the plastic film. Then, telescopic rod 1 of pushing device 1 extends forward, driving pushing plate 1 to extend and retract together. Pushing plate 1 pushes the PCB to the back of sealing device 1 of the heat sealer.

[0026] S32. The heat sealer seals the plastic film. Hydraulic pump 1 controls sealing device 1 to descend via telescopic rod 2. Heating device 1 heats sealing plate 1. The heated sealing plate seals and cuts the plastic film. After sealing, hydraulic pump 1 controls sealing device 1 to ascend. A lifting plate is fixed to sealing device 1 and ascends and descends along with sealing device 1. The sealing plate seals and cuts one side of the plastic film and then rises. When the lifting plate rises, it lifts the plastic film that passes above it, making it easier to push in the next PCB board.

[0027] S33, the camera detects the condition of the PCB board. If it detects that the sealing effect of the PCB board after the first pass of the heat sealer does not meet the standard, the operating table will light up a red light as a warning. If it detects that the sealing effect is qualified, the vacuum secondary sealing machine will continue the vacuum sealing operation;

[0028] S34, the packaged PCB board is vacuum-sealed by the vacuum secondary sealing machine, and the PCB board is conveyed to the sealing device 2 of the vacuum secondary sealing machine by the conveyor belt 2. When the camera detects that the qualified PCB board passes through the vacuum secondary sealing machine, the pressing plate in the detection device will press the packaged PCB board through the telescopic device, and the pressing plate in the detection device will press the packaged PCB board through the telescopic device. The vacuum suction nozzle moves into the packaging bag through the slide rail 1 to extract vacuum. After the vacuum extraction is completed, the vacuum suction nozzle leaves the packaging bag again through the slide rail 1, and the sealing device 2 slides through the slide rail 2 to seal the packaging bag. After the sealing is completed, the sealing device 2 rises, and then the fan dissipates heat to the sealing part of the packaging bag. After the heat dissipation is completed, the sealing device 2 descends again to perform secondary sealing on the sealing part. After the secondary sealing is completed, the pressing plate is lifted by the telescopic device. After the PCB board is packaged, it is conveyed out along the conveyor belt 2. The vacuum extraction time and the lifting and lowering of the sealing device can be operated through the operating table.

[0029] After adopting the above technical solution, the beneficial effects of the present invention are:

[0030] (1) After a piece of plastic roll film is folded in half, only two edges of the plastic film need to be sealed, which reduces the number of sealing times, improves efficiency and saves costs.

[0031] (2) After the plastic bag is vacuum sealed, a secondary sealing operation is performed to reduce air leakage in the packaging bag in the later stage, ensure the sealing effect, prevent the circuit board from being contaminated, and facilitate storage and transportation.

[0032] (3) The camera can detect the condition of the PCB board. If it is detected that the PCB board does not meet the sealing standard after passing through the heat sealer for the first time, the operating table will light up a red light as a warning. If the sealing is qualified, the vacuum secondary sealing machine will continue the vacuum sealing operation. When the camera detects that the qualified PCB board passes through the vacuum secondary sealing machine, the pressing plate in the detection device will press the packaged PCB board through the telescopic device, realizing intelligence.

[0033] (4)PCB board loading, bagging, vacuuming and sealing are all set on one machine, which is more convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

S3, PCB board packaging process, specifically including the following steps: S31, after the pushing device 1 (33) pushes the PCB board on the workbench (36) to the heat sealing machine (8), the PCB board stops after being transported to the designated position, the pushing plate 2 (32) on the pushing device 2 (29) slides through the slide rail 3 (31) to push the PCB board from the conveyor belt 1 (37) to the plastic film, and then the telescopic rod 1 (34) of the pushing device 1 (33) begins to extend forward, and the telescopic rod 1 (34) drives the pushing plate 1 (35) to extend and retract together, and the pushing plate 1 (35) pushes the PCB board to the back of the sealing device 1 (12) of the heat sealing machine (8); S32, the heat sealing machine (8) seals the plastic film, the hydraulic pump (39) controls the sealing device (12) to descend through the telescopic rod (40), the heating device (10) heats the sealing plate (13), and the heated sealing plate (13) seals and cuts the plastic film. After the sealing is completed, the hydraulic pump (39) controls the sealing device (12) to rise, and the lifting plate (11) is fixed on the sealing device (12). As the sealing device (12) rises and falls, the sealing plate (13) seals and cuts one side of the plastic film and then rises. When the lifting plate (11) rises, it will lift the plastic film passing above it, making it convenient for the next PCB board to be pushed in. S33, the camera (25) detects the condition of the PCB board. If it is detected that the sealing effect of the PCB board after the first passing of the heat sealing machine (8) does not meet the standard, the operating table (15) will light up a red light as a warning. If it is detected that the sealing is qualified, the vacuum secondary sealing machine (14) will continue the vacuum sealing operation; S34, the packaged PCB board is vacuum sealed by the vacuum secondary sealing machine (14), and the PCB board is conveyed to the sealing device 2 (28) of the vacuum secondary sealing machine (14) by the conveyor belt 2 (38). When the camera detects that the qualified PCB board passes through the vacuum secondary sealing machine, the pressing plate in the detection device will press the packaged PCB board through the telescopic device, and the pressing plate (24) in the detection device (27) will press the packaged PCB board through the telescopic device (26). The vacuum suction nozzle (23) moves into the packaging bag through the slide rail 1 (19) to extract the vacuum. After the vacuum extraction is completed, Afterwards, the vacuum suction nozzle (23) leaves the packaging bag through the slide rail 1 (19), and the sealing device 2 (28) slides through the slide rail 2 (20) to seal the packaging bag. After the sealing is completed, the sealing device 2 (28) rises, and then the fan (21) dissipates heat to the sealed part of the packaging bag. After the heat dissipation is completed, the sealing device 2 (28) descends again to perform a secondary sealing on the sealed part. After the secondary sealing is completed, the pressing plate (24) is lifted by the telescopic device (26). After the PCB board is packaged, it is conveyed out along the conveyor belt 2 (38). The vacuum extraction time and the lifting and lowering of the sealing device can be operated through the operating table.
