Description

Technical Field

[0001] This utility model relates to the field of PCB board stacking, specifically a recycling component for 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 lifts the substrate and the PCB boards placed on the substrate to a designated height. Then, the suction cups suck the PCB boards away. After all the PCB boards are sucked away, the substrate remains on the loading section, affecting the loading section's reloading.

[0005] Therefore, there is a need to provide a recycling component to recycle the substrate, move the substrate from the loading section to a predetermined position, thereby preventing the substrate from affecting the next loading of the loading section and affecting the loading cycle.

[0052] The transmission gear 2312 is located near both ends of the base fork arm 231.

[0053] 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 adapted to the drive chain 2313, and the two sides are respectively provided with a first transmission group 2322 and a second transmission group 2323.

[0055] This invention uses an adjustment unit to drive the recovery fork 23 to a predetermined position. The recovery fork 23 extends to the bottom of the substrate, and the adjustment unit drives the recovery fork 23 to support the substrate and place it in the predetermined position, thereby completing the recovery of the substrate and preventing the substrate from affecting the next feeding of the feeding section and affecting the feeding cycle.

[0057] The lifting component 22 includes two sets, symmetrically installed on the extension slide 213. Each set includes a lifting base frame 221 installed on the extension slide 213, a lifting cylinder 222 and a lifting guide rod 224 connected to the lifting base frame 221, a lifting shaft 223 set at the output end of the lifting cylinder 222, and a lifting frame 225 connected to the lifting shaft 223 and sleeved on the lifting guide rod 224.

[0058] The position of the recycling fork 23 is adjusted by designing an adjustment unit, which can then support the substrate to complete the substrate recycling process.

[0059] The first transmission assembly 2322 includes:

[0060] The first adapter gear 2322D is disposed at one end of the first-stage fork arm 232;

[0061] The first transmission chain 2322A meshes with the first adapter gear 2322D.

[0062] In a further embodiment, the second transmission group 2323 includes:

[0063] The second adapter gear 2323D is disposed at the other end of the first-stage fork arm 232;

[0064] 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.

[0065] The first-stage fork arm 232 has grooves on both sides that are adapted to the first transmission chain 2322A and the second transmission chain 2323A;

[0066] When the primary fork arm 232, secondary fork arm 233 and basic fork arm 231 slide, friction is reduced by pulleys, which are designed on the contact surface of each fork arm.

[0067] 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.

[0068] 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.

[0069] By designing the recycling fork arm 23, the recycling of the substrate is completed. At the same time, the recycling fork arm 23 is bidirectional, which can recycle the substrates at both ends, so that one recycling component can be matched with two feeding parts.

[0070] The basic fork arm 231 is mounted on the lifting frame 225.

[0071] Working principle description: During operation, the extension motor 214 drives the extension screw 215 to rotate, which in turn drives the extension slide 213 to slide along the extension slider. The distance between the recovery fork arm 23 and the base plate is adjusted. After the adjustment is appropriate, the gear motor drives the drive chain 2313 to move, which in turn drives the first-stage rack 2321 to move, which in turn drives the first-stage fork arm 232 to slide along the base fork arm 231.

[0072] When moving in the first direction (with attachment) Figure 3 , 5 (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.

[0073] When moving in the second direction (as shown in the appendix) Figure 3, 5 (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.

[0074] 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. Through the coordination of the adjustment unit and the recovery fork arm 23, the substrate is placed in the predetermined position, thus completing the substrate recovery work.

[0075] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
