Description

Technical Field

[0001] This utility model relates to the field of PCB board stacking, specifically a stacking component of an automatic PCB board stacking device. Background Technology

[0002] A PCB, or Printed Circuit Board, is an indispensable basic component in modern electronic devices, undertaking the crucial tasks of connecting, supporting, and protecting electronic components.

[0003] PCBs are typically multi-layered, and the materials used in multi-layered PCBs vary. When making high-multilayer PCBs, the PCBs need to be stacked to achieve the desired number of layers.

[0004] When the PCB boards are stacked, the AGV trolley transports the PCB boards to the designated position. The loading section drives the substrate and the PCB boards placed on the substrate to rise to a designated height, so that the stacking assembly can pick up the PCB boards.

[0005] During this process, the substrate needs to be placed back into the AGV cart for the next PCB transport. Traditionally, after all the PCBs have been picked up, the substrate is lowered by the loading section and placed on the AGV cart. At this time, the AGV cart needs to wait in place until the substrate is placed back on the AGV cart before leaving the position. In this case, the stacked components occupy the AGV cart for too long, and a lot of time is wasted waiting in place, which affects the working efficiency of the AGV cart. Utility Model Content

Then, the subsequent AGV trolley continues to the feeding unit 3, and the feeding unit 3 repeats the work, lifting the substrate and PCB board and suspending it at the predetermined position. At this time, the adjustment unit of the recovery unit 2 drives the recovery fork arm 23 to place the substrate on the AGV trolley for the next feeding.

[0099] The position of the recycling fork 23 is adjusted by designing an adjustment unit, so that the substrate can be supported by the recycling fork 23 to complete the substrate recycling work.

[0100] The recovery fork arm 23 includes:

[0101] A basic fork arm 231 is mounted on a lifting frame 225. An input gear 2311 and multiple sets of transmission gears 2312 are provided on the inner side of the basic fork arm 231. A drive chain 2313 is adapted to the input gear 2311 and the transmission gears 2312. A gear motor connected to the input gear 2311 is provided on the side of the basic fork arm 231.

[0102] The transmission gear 2312 is located near both ends of the base fork arm 231.

[0103] A primary fork arm 232 is slidably connected to the base fork arm 231. The bottom of the primary fork arm 232 is provided with a primary rack 2321, and the two sides are respectively provided with a first transmission group 2322 and a second transmission group 2323.

[0104] The first-stage fork arm 232 has slots on both sides that are adapted to the first transmission group 2322 and the second transmission group 2323;

[0105] The secondary fork arm 233 is slidably connected along the primary fork arm 232.

[0106] The primary rack 2321 is adapted to the drive chain 2313;

[0107] The first transmission group 2322 includes:

[0108] The first adapter gear 2322D is disposed at one end of the first-stage fork arm 232;

[0109] The first transmission chain 2322A meshes with the first adapter gear 2322D. One end is provided with a first fork arm connecting block 2322B that is connected to the secondary fork arm 233, and the other end is provided with a first base connecting block 2322C that is connected to the base fork arm 231 after rotating through the first adapter gear 2322D.

[0110] The second transmission group 2323 includes:

[0111] The second adapter gear 2323D is disposed at the other end of the first-stage fork arm 232;

[0112] The second transmission chain 2323A meshes with the second adapter gear 2323D. One end of the chain rotates through the second adapter gear 2323D and is provided with a second fork arm connecting block 2323B that is connected to the secondary fork arm 233. The other end of the chain is provided with a second base connecting block 2323C that is connected to the base fork arm 231.

[0113] The first basic connecting block 2322C and the second basic connecting block 2323C are at a predetermined distance, and the first basic connecting block 2322C and the second basic connecting block 2323C are respectively close to the two ends of the basic fork arm 231. The specific position can be selected according to the stroke.

[0114] The first fork arm connecting block 2322B and the second fork arm connecting block 2323B are at a predetermined distance, and the first fork arm connecting block 2322B and the second fork arm connecting block 2323B are respectively close to the two ends of the secondary fork arm 233. The specific position can be selected according to the stroke.

[0115] By designing the recovery fork arm 23, the pallet can be recovered. At the same time, the recovery fork arm 23 is bidirectional, and the two sets of feeding parts 3 only need to be paired with one set of recovery parts 2 to complete the recovery of the substrate of the two sets of feeding parts 3.

[0116] The transmission unit includes a first transmission module 4 and a second transmission module 5 arranged in parallel.

[0117] The first transmission module 4 and the second transmission module 5 are existing technologies, differing only in roller density and performing only transmission work. They may include a transmission frame connected to the cover 1, multiple sets of transmission rollers set on the transmission frame, transmission wheels at the ends of the multiple sets of transmission rollers, transmission belts fitted on the transmission wheels, and a transmission motor installed on the transmission frame to drive the transmission belts to move, thereby driving the multiple sets of transmission wheels to rotate, thus completing the rotation of the multiple sets of transmission rollers.

[0118] Alternatively, it can be achieved through gear meshing. Gears are fitted onto the ends of multiple sets of transmission rollers, and an additional gear is added between adjacent gears. The transmission motor drives any one of the gears to complete the drive.

[0119] The first transmission module 4 and the second transmission module are used to transmit PCB boards and partition paper, respectively. In actual operation, the AGV trolley transports PCB boards. In order to avoid interference between PCB boards, partition paper is placed between every two PCB boards, and a substrate is designed at the bottom of the bottom PCB board for the AGV trolley to transport.

[0120] During stacking, multiple stacking components need to be designed and set up side by side. Each feeding section 3 feeds PCBs of different layers, and then the PCBs are transferred through the transfer section and stacked by the pick-up section.

[0121] The design of the first transmission module 4 and the second transmission module 5 allows for the separate placement of PCB boards and spacers, thereby enabling the PCB board stacking to present an automated assembly line, resulting in higher stacking efficiency.

[0122] The suction unit includes:

[0123] A linear module 61 is mounted on top of the housing 1;

[0124] The lifting module 62 is connected to the linear module 61;

[0125] The tray frame 63 is connected to the lifting module 62, and the bottom of the tray frame 63 is provided with multiple suction cups 64;

[0126] The linear module 61 and the lifting module 62 are existing technologies and can be selected by those skilled in the art according to actual needs;

[0127] Specifically, the linear module 61 may include a linear module 61 frame connected to the housing 1, a slide groove designed on the linear module 61 frame, a linear lead screw inserted into the linear module 61 frame, a linear motor connected to the linear lead screw installed at the end of the linear module 61 frame, and a linear slider adapted to the slide groove fitted on the linear lead screw. During operation, the linear motor drives the linear lead screw to rotate, which drives the linear slider to slide on the slide groove to complete linear motion.

[0128] During operation, the linear motor drives the linear lead screw to rotate, which in turn drives the linear slider to move, thus completing the linear motion.

[0129] The lifting module 62 can adopt the same or similar structure as the linear module 61, specifically including a lifting module 62 frame, a lifting screw inserted into the lifting module 62 frame, a sliding groove opened on the lifting module 62 frame, an upgrade slider adapted to the sliding groove sleeved on the lifting screw, and a lifting motor that is driven or directly connected to the lifting screw installed at one end of the lifting module 62 frame.

[0130] During operation, the lifting motor drives the lifting screw to rotate, which in turn moves the lifting slider to complete the lifting motion.

[0131] Connect the 62 lifting modules to the linear slider, and connect the connecting frame to the lifting slider;

[0132] Connect the lifting slider to the plate frame 63.

[0133] By designing the suction section, the PCB board is suctioned and then stacked on the transfer section.

[0134] Working principle description: During operation, the feeding motor 313 drives the feeding screw 312 to rotate, which in turn drives the feeding slide plate 314 to move along the feeding guide rod 311. This, in turn, drives the feeding arm 315 to lift the substrate on the AGV trolley and the PCB board placed on the substrate. After rising to the predetermined height, the limit cylinder 323 drives the inner baffle to flip and become horizontal, thus supporting the bottom of the substrate. At this time, the substrate and PCB board are suspended. The suction part picks up the PCB board onto the first transmission module 4 and picks up the partition paper onto the second transmission module 5. When multiple stacking components work together, the stacking of the PCB board is completed.

[0135] When the suction unit adsorbs, the linear module 61 and the lifting module 62 work together to move the tray 63 to a suitable position and then adsorb it through the suction cup 64.

[0136] After the PCB board is adsorbed, the substrate is placed on the AGV trolley for the next material transport through the recycling section 2. During operation, the extension motor 214 drives the extension screw 215 to rotate, which drives the extension slide 213 to slide along the extension slider. The distance between the recycling fork arm 23 and the substrate is adjusted. After the adjustment is appropriate, the gear motor drives the drive chain 2313 to move, which drives the first-stage rack 2321 to move, which drives the first-stage fork arm 232 to slide along the base fork arm 231.

[0137] When moving in the first direction (with attachment) Figure 4 , 6(The extension directions shown are opposite) When the first-stage fork arm 232 moves in the first direction, the first-stage fork arm 232 drives the first adapter gear 2322D to move in the first direction. At this time, the first transmission chain 2322A that passes through the rotating part of the first adapter gear 2322D becomes longer, thereby driving the second-stage fork arm 233 to move along the first-stage fork arm 232 in the first direction.

[0138] When moving in the second direction (as shown in the appendix) Figure 4 , 6 (Extended direction shown) When the first-stage fork arm 232 moves in the second direction, the first-stage fork arm 232 drives the second adapter gear 2323D to move in the second direction. At this time, the second transmission chain 2323A that passes through the rotating part of the second adapter gear 2323D becomes shorter, thereby driving the second-stage fork arm 233 to move along the first-stage fork arm 232 in the second direction.

[0139] This causes the secondary fork arm 233 to move to the bottom of the substrate. Then, the lifting cylinder 222 drives the lifting shaft 223 to move, which in turn drives the lifting frame 225 to move along the lifting guide rod 224. This causes the secondary fork arm 233 to support the substrate and then retract. At this time, the AGV trolley carrying the substrate and PCB board for the second loading moves to the designated position and continues to load through the loading unit 3. After loading, it is suspended by the limiting unit 32. Then, the recycling unit 2 places the substrate that was recycled in the first loading onto the loading arm 315. Finally, the loading unit 31 places the substrate onto the AGV trolley, completing the substrate recycling work.
