Description

Technical Field

[0001] The invention relates to the technical field of packaging and transportation, and in particular to a PCB board packaging device that can adapt to large and small board surfaces. Background Art

[0002] PCB boards are basic components in electronic devices, and their sizes and shapes vary depending on application requirements. Traditional packaging equipment often has difficulty adapting to PCB boards of different sizes, resulting in low packaging efficiency. The original intention of designing PCB board packaging equipment that can adapt to large and small boards is to solve the inconvenience caused by size differences in the packaging process of PCB boards. By improving its adaptability and flexibility, the packaging efficiency is significantly improved. It has the ability to adjust the packaging size and shape to ensure that PCB boards of different sizes can be properly packaged, thereby improving production efficiency and product quality.

[0003] The vacuum sealer uses a built-in vacuum pump to extract the air from the packaging bag to create a vacuum environment, and then uses a sealing device to seal the packaging bag.

[0004] However, in the existing PCB board packaging equipment, the PCB board needs to be placed in the packaging equipment by means of transmission. During the operation of the existing transmission equipment, the internal motor, gears, and belts generate vibrations when acceleration or rotation occurs, and then they will cause the PCB board placed on the surface of the transmission equipment to vibrate through force transmission. The vibration of the transmission equipment causes the PCB board to easily have position deviations during the transmission process, or the transmission speed of the transmission equipment is fast during the transmission process, causing the position of the PCB board to deviate from its center, increasing the risk of incomplete packaging due to incorrect position when entering the packaging equipment. For stacked PCB boards, the shortcomings of the existing transmission equipment will be more obvious, that is, it will cause stacking misalignment and offset during the transmission process, making it more likely for the stacked PCB boards to have packaging misalignment problems during packaging, and even damage the PCB boards, affecting the overall product quality.

[0005] Secondly, after packaging, existing packaging equipment usually places PCB boards in a stacking manner. The traditional stacking method causes uneven pressure distribution on the PCB boards during subsequent transportation. In particular, the bottom PCB boards often bear greater pressure, increasing the risk of damage. The unreasonable stacking method causes inconvenience in subsequent PCB board placement, affecting work efficiency. At the same time, existing equipment often has problems such as PCB board blockage and poor discharge during the discharge process, requiring manual intervention and adjustment, increasing labor intensity and time cost.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The reciprocating motion of the telescopic rod pushes the alignment plates on both sides to move closer to the middle of the conveyor belt. At the same time, the elastic expansion and contraction of the reset spring restores the alignment plates on both sides to their initial state, thereby realizing the alignment of the PCB board when it is transmitted on the upper surface of the conveyor belt. The automatic adjustment function ensures that the PCB board maintains a stable center position during the transmission process, thereby reducing the position deviation of the PCB board caused by the vibration of the transport body, thereby reducing the problem of incomplete packaging of the PCB board due to position deviation. For stacked PCB boards, it can also reduce the misalignment during the stacking process;

[0019] Among them, the telescopic function of the telescopic rod can adapt to PCB boards of different sizes, which improves the versatility and adaptability of the equipment;

[0020] The setting of the limit telescopic plate limits the maximum distance between the two sides of the alignment plates, thereby preventing the alignment plates from being over-fitted and squeezing the PCB board;

[0021] 2. The PCB board is tilted and supported by the tilted positioning plate and the limit plate, so that the PCB board is tilted after subsequent packaging. The PCB board is also tilted in the subsequent stacking process, thereby dispersing the pressure caused by traditional stacking and reducing the risk of damage to the PCB board due to stacking during transportation.

[0022] 3. The extension of the pushing rod drives the pushing plate to push the tilted PCB board out of the packaging shell and into the discharge box, thereby realizing the automatic placement of the PCB board. At the same time, the discharge box is pushed to move during the extension of the pushing rod to prevent the front PCB board from blocking the rear PCB board, resulting in poor discharge. This ensures that each PCB board can enter the discharge box smoothly, reducing the need for manual handling and sorting of PCB boards.

[0023] Among them, a tilting block is arranged inside the discharge box to enable the tilted PCB boards to be synchronously tilted and stacked, further making it convenient for the PCB boards to be taken and placed later. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In the initial state: the sliding rod 34 is located at the lowest position inside the sliding arc groove 33, the limit plate 35 is close to the positioning plate 32, the return spring 42 is not stretched, the rotating block 410 is away from the squaring plate 43, the telescopic rod 412 is in a telescopic state, the limit telescopic plate 416 is in an extended state, the pushing rod 53 is located inside the pushing groove 52 and away from the discharge box 62, the pushing plate 54 is close to the driving cylinder 51, the limit block 57 is not located inside the limit structure 55, and the limit block 57 is aligned with the semi-arc groove inside the limit structure 55, the fixed gear block 58 is engaged with the rotating gear 512, and the discharge box 62 slides inside the discharge groove 61 and is located at the end away from the support leg 22.

[0057] When working:

[0058] PCB board alignment:

[0059] The operator places the PCB board on the upper surface of the conveyor belt 24 away from the end of the packaging shell 1, and then the operator electrically controls the built-in drive motor to start through the external controller, and the built-in drive motor starts to drive the drive shaft 23 driven to be installed on the built-in drive motor to rotate, and the drive shaft 23 driven to be installed on the built-in drive motor rotates through the conveyor belt 24 to drive another drive shaft 23 to rotate synchronously, at this time, through the transmission of the conveyor belt 24, the PCB board on the upper surface of the conveyor belt 24 will be transmitted to the inside of the packaging shell 1;

[0060] In the above, the driving shaft 23 rotates to drive the connecting shaft 414 fixedly connected thereto to rotate, and the connecting shaft 414 rotates to drive the driving bevel gear 415 to rotate. Because the driving bevel gear 415 is meshed with the linkage bevel gear 46, the driving bevel gear 415 rotates to drive the linkage bevel gear 46 to rotate, and the linkage bevel gear 46 rotates to drive the fixed column 45 to rotate. The fixed column 45 rotates through the transmission of the conveyor belt 2 413 to drive the support column 48 to rotate, and the support column 48 rotates to drive the rotating disk 49 to rotate. The rotating disk 49 rotates to drive the rotating block 410 to rotate with the axis of the rotating disk 49 as the center of the circle. Because the rotating block 410 is slidably connected to the inside of the sliding slot block 411, the rotating block 410 rotates to drive itself to slide inside the sliding slot block 411, and at the same time, the rotating disk 49 rotates to drive the sliding slot block 411 to reciprocate left and right, and the sliding slot block 411 reciprocates left and right When the swivel block 410 moves to the initial state in the reciprocating motion, the swivel block 410 will contact the swivel plate 43 and push the swivel plate 43 to move toward the middle of the conveyor belt 24. The swivel plate 43 moves toward the middle of the conveyor belt 24 and swivels the PCB board on the upper surface of the conveyor belt 24. At the same time, the swivel plate 43 moves toward the middle of the conveyor belt 24, driving the reset spring 42 to be stretched. At the same time, the swivel plate 43 moves toward the middle of the conveyor belt 24 to squeeze the limit telescopic plate 416. After being squeezed, the limit telescopic plate 416 will change from an extended state to a contracted state. When the rotating block 410 moves to the initial state in the reciprocating motion, the swivel plate 43 is driven to return to the initial state under the elastic contraction of the reset spring 42. At the same time, the limit telescopic plate 416 returns to the initial state.

[0061] Among them, when the PCB board is large, when the telescopic rod 412 pushes the aligning plate 43 to move, the aligning plate 43 will conflict with the outer surface of the PCB board, that is, the aligning plate 43 is subjected to the stress of the PCB board itself. At this time, under the action of the stress, the aligning plate 43 is subjected to a reverse pushing force, and the reverse pushing force pushes the telescopic rod 412 to contract. The telescopic function of the telescopic rod 412 can adapt to PCB boards of different sizes, thereby improving the versatility and adaptability of the equipment. The traditional cylinder pushing method can often only adapt to PCB boards within a fixed size or shape range. Once this range is exceeded, the cylinder parameters need to be replaced or adjusted, which has poor flexibility. In addition, as a wearing part in mechanical equipment, the cylinder has a relatively high maintenance cost. The driving source of the above movement is the transport body 2. The transport body 2 serves as the power for driving the transmission of the PCB board, and can also synchronously drive the telescopic rod 412 to realize the alignment function, thereby reducing the energy consumption of adding an additional driving source. At the same time, the above movement can automatically adjust the alignment range according to the size of the PCB board, which has good flexibility.

[0062] PCB board packaging:

[0063] When the PCB board enters the packaging shell 1 with the transmission of the conveyor belt 24, the PCB board falls to the upper surface of the packaging film 14 under the action of gravity and the guidance of the limiting arc plate 36. The PCB board that falls to the upper surface of the packaging film 14 will slide down along the sliding arc groove 33 and the inclined surface of the limiting plate 35, thereby making the PCB board present an inclined state. At this time, the operator electrically controls the vacuum sealer to package the PCB board through the external controller. When it is necessary to package the stacked PCB boards, the stacked PCB boards fall to the upper surface of the packaging film 14 under the action of gravity. Finally, because they are stacked, the stacked PCB boards will squeeze the gap between the positioning plate 32 and the limiting plate 35, that is, the stacked PCB boards squeeze the limiting plate 35 to move toward the end away from the positioning plate 32, and the movement of the limiting plate 35 drives the sliding rod 34 to slide inside the sliding arc groove 33 toward the end away from the positioning plate 32. Similarly, the operator finally controls the vacuum sealer to pack the PCB boards through the external controller. The PCB boards are tilted and supported by the tilted setting of the positioning plate 32 and the limiting plate 35, so that the PCB boards are in a tilted state after subsequent packaging.

[0064] Removal and placement of PCB boards:

[0065] When the PCB board is packaged, the PCB board is in an inclined state and fits the outer surface of the positioning plate 32. The operator electrically controls the drive cylinder 51 through the external controller to start. The drive cylinder 51 starts and pushes the pushing rod 53 to slide inside the pushing groove 52 toward the end close to the discharge port 64. The sliding of the pushing rod 53 drives the pushing plate 54 to move toward the end close to the discharge port 64. The movement of the pushing plate 54 will conflict with the PCB board. At the same time, the movement of the pushing plate 54 will push the PCB board out of the packaging shell 1 into the discharge box 62.

[0066] In the above, the pushing rod 53 slides and drives the fixed gear block 1 58 to move toward the end close to the discharge port 64. Since the fixed gear block 1 58 is meshed with the rotating gear 512, the movement of the fixed gear block 1 58 drives the rotating gear 512 to rotate, and the rotation of the rotating gear 512 drives the rotating shaft 1 511 to rotate. The rotation of the rotating shaft 1 511 drives the rotating shaft 2 515 to rotate through the transmission of the conveyor belt 3 513. The rotation of the rotating shaft 2 515 drives the transmission bevel gear 516 to rotate. Since the transmission bevel gear 516 is meshed with the matching bevel gear 519, and by Fig. 9It can be known that the transmission bevel gear 516 is smaller than the matching bevel gear 519, that is, the small gear drives the large gear in a subtraction motion, and the speed of the matching bevel gear 519 is lower than that of the transmission bevel gear 516. The matching bevel gear 519 rotates to drive the rotating shaft 3 518 to rotate inside the positioning block 3 517, and the rotating shaft 3 518 rotates to drive the moving gear 520 to rotate. Because the moving gear 520 is meshed with the fixed gear block 2 63, the movement of the moving gear 520 drives the fixed gear block 2 63 to move. Since the fixed gear block 2 63 is fixedly connected to the bottom of the discharge box 62, the movement of the fixed gear block 2 63 will drive the discharge box 62 to move inside the discharge trough 61 toward the end close to the support leg 22, thereby realizing that each time the PCB board is pushed into the discharge box 62, the discharge box 62 will undergo a certain displacement, leaving space for the subsequent PCB board to be placed, ensuring that each PCB board can smoothly enter the discharge box 62, reducing the need for manual handling and sorting of PCB boards.

[0067] In the above, the pushing rod 53 slides and drives the limit block 57 to move toward the end close to the discharge port 64. As the limit block 57 moves, it slides inside the transverse groove of the limit structure 55. Fig.13 It can be known that the continuous sliding of the pushing rod 53 will drive the limit block 57 to move along the transverse groove of the limit structure 55 toward the semi-arc groove. When the limit block 57 rotates to the inside of the semi-arc groove, due to the internal shape of the semi-arc groove, the limit block 57 rotates upward, and the movement of the limit block 57 drives the one-way plate 521 to rotate. The rotation of the one-way plate 521 will no longer block the straight groove and the semi-arc groove, and the limit block 57 will move to the inside of the straight groove, that is, the rotation of the limit block 57 drives the pushing rod 53 to rotate, and the rotation of the pushing rod 53 drives the fixed gear block 58 to rotate inside the rotating groove 56. After the fixed gear block 58 rotates, it will no longer mesh with the rotating gear 512. That is, when the discharge box 62 has a certain displacement, the rotating gear 512 will no longer rotate;

[0068] In the above, the one-way plate 521 blocks the straight groove and the semi-arc groove again under the action of gravity. Finally, when the PCB board is pushed into the discharge box 62, the driving cylinder 51 drives the pushing rod 53 to restore the initial state, that is, the pushing rod 53 slides inside the pushing groove 52 toward the end away from the discharge box 62. Because the one-way plate 521 blocks the straight groove and the semi-arc groove, the sliding of the pushing rod 53 drives the limit block 57 to slide inside the straight groove of the limit structure 55, and at the same time, the sliding of the pushing rod 53 drives the fixed gear block 58 to slide synchronously. When the pushing rod 53 slides inside the rotating groove 56 and the fixed tooth block 58 does not mesh with the rotating gear 512 during the sliding process, after the pushing rod 53 moves to the initial state, the limit block 57 is no longer located inside the limit structure 55. Because the limit block 57 is made of a metal iron block, the limit block 57 drives the pushing rod 53 to rotate under the action of its own gravity, thereby aligning the limit block 57 with the semi-straight arc groove inside the limit structure 55. At the same time, the rotation of the pushing rod 53 will mesh the fixed tooth block 58 with the rotating gear 512 again.
