Description

Technical Field

[0001] The present invention relates to the technical field of PCB board production, and specifically to an upper suction and transfer integrated machine. Background Art

[0002] A PCB board is a board that forms electrical connections between electronic components by patterning and laying conductive copper foils on the surface of insulating materials (such as fiberglass, epoxy resin, etc.). It is an essential component in modern electronic devices and mainly consists of a substrate, copper foil, solder pads, solder mask, and silk screen layer. PCB boards are mainly used to provide electrical connections, support components, and optimize spatial layouts, and are widely used in various electronic devices, such as communication devices, medical devices, industrial control and automation, automotive electronics, household appliances, computers and servers, and Internet of Things devices.

[0003] In the field of PCB board manufacturing, its production process usually includes multiple processes such as substrate cutting, inner layer circuit production, interlayer alignment and lamination, mechanical drilling, hole metallization, electroplating copper thickening, pattern transfer and etching, solder mask coating, silk screen character marking, and forming and testing. Among them, the material transfer and loading / unloading operations between each process, as the connecting links, directly affect the overall production capacity. Currently, after the PCB boards are framed, manual unloading and transfer are generally used. This method can still operate in small-batch production, but it will increase the loss of human and material resources in large-batch production and reduce the overall production efficiency.

[0019] Specifically, the bare-board conveying frame is composed of a base frame, two anti-tilting stop rods 27, two material frame positioning strips 28, two stop rod movable guide shafts 29, a PCB drag board 30, two lifting drag strips 31, two lifting guide shafts 32, two stop rod movable guide rails 33, and three bare-board frame clamping cylinders 6.

Cooperating with the set bare-board tray lifting mechanism 5, the vertical lifting and conveying of the PCB board is completed. The bare-board frame clamping cylinder 6 is used to clamp the base frame.

[0020] Hooking board mode 1: The AGV trolley transports the material frame filled with PCBs and automatically transports the material frame to the lifting platform 1 or lifting platform 2 via the lower material frame in-and-out conveyor table 8. After the material frame is in place, the lifting platform 1 or lifting platform 2 is lifted to the specified position, and the hooking and suction plate mechanism 3 is translated to the set position and starts to hook the board layer by layer. The PCBs of lifting platform 1 or lifting platform 2 are respectively hooked to track 1 37 and track 2 38 to wait for the lower computer to send a board signal and then transported to the lower computer. After the whole frame of PCBs is emptied, the empty material frame is output to the AGV trolley via the lower material frame in-and-out conveyor table 8 for transportation away. This reciprocating process is repeated. Lifting platform 1 transports from the front and lower layers, and lifting platform 2 transports from the back. The AGV trolley must run to the front and rear sides of the equipment.

[0021] Hooking board mode 2: The AGV trolley transports the material frame filled with PCBs and automatically transports the material frame to the lifting platform 1 or the lifting platform 2 via the lower material frame in-and-out conveyor platform 8. After the material frame is in place, the lifting platform 1 or the lifting platform 2 is lifted to the specified position, and the hooking and suction plate mechanism 3 is translated to the set position and starts to hook the board layer by layer. The PCBs of the lifting platform 1 or the lifting platform 2 are respectively hooked to the track 1 37 and the track 2 38 to wait for the lower machine to send a signal for the board and then transported to the lower machine. After the whole frame of PCBs is emptied, the empty material frame is output to the AGV trolley via the lower material frame in-and-out conveyor platform 8 for transportation away, and so on. The two material frames in and out of the conveyor platform 8 use the upper and lower conveyor platforms on the same side. The AGV trolley only needs to travel to the front or rear side of the equipment, and the material frame located in the track 1 37 is transported to the lifting platform 1, the lifting limit cylinder group 21 descends, and the material frame continues to be transported to the lifting platform 2, the lifting limit cylinder group 21 lifts and limits, and the light board frame clamping cylinder 6 clamps the material frame.

[0022] Board suction mode: the AGV trolley transports the light board frame filled with PCBs to the light board frame conveying platform 7. After the light board frame is in place, the light board frame clamping cylinder 6 clamps it, the light board tray lifting mechanism 5 drags the lifting drag strip 31 to the set position, the hook and suction plate mechanism 3 moves horizontally to the set position and descends, the movable suction cup 13 starts to suck the board, the hook and suction plate mechanism 3 moves horizontally to the double-track PCB translation conveying track 4, the movable suction cup 13 descends and places the PCB on track 1 37 or track 2 38 waiting for the lower machine to transport the board to the lower machine, after all the PCBs are sucked, the light board frame is transported to the AGV trolley for transportation, waiting for the full frame to be transported back.

[0023] According to the above, the present invention realizes the input and output operations of the material frame synchronously by setting the material frame in-and-out conveyor table 8 with upper and lower double-layer distribution and using the double-station collaborative conveying method, ensuring the continuity of material flow, and solving the technical problem of low connection efficiency caused by the dependence on manual handling in the existing PCB board transfer. Secondly, since the upper and lower conveyor tables operate independently and are automatically docked with the AGV cart, the material waiting time is significantly reduced and the overall production capacity is improved. Thirdly, the hook and suction plate mechanism 3 integrates the adsorption component and the hook plate component, which can complete the adsorption and grasping and the hooking and releasing actions of the PCB board, ensuring the coherence of loading and transfer. Finally, the double-track PCB translation conveyor track 4 adopts a parallel layout of track one 37 and track two 38, and by using the method of driving the screw mechanism to adjust the track gauge with the one-track width adjustment motor 43 and the two-track width adjustment motor 40, it can adapt to the conveying requirements of different specifications of PCB boards and ensure multi-size compatibility.
