Description

Technical Field

[0001] The present disclosure relates to the field of SMT processing, and in particular to a PCB board loading and suction device and equipment thereof. Background Art

[0002] A PCB (Printed Circuit Board), also known as a printed circuit board or printed circuit board, is a substrate used to assemble electronic components. After production and processing, PCBs are stored in PCB racks. These racks are then transferred to the PCB loading device on the SMT production line for loading. For example, patent application number CN202321898940.8 - A PCB rack loading and unloading device.

[0003] The PCB board frame to be loaded is transported to the lifting assembly by the transport device of the lower layer, and the PCB board frame to be loaded is lifted up by the lifting assembly. During the lifting process, the PCB boards in the PCB board frame are pushed one by one onto the feeding assembly by the pushing plate assembly, and then the PCB boards are sent to the next process by the feeding assembly. Although continuous loading of a single PCB board frame can be achieved, the empty frame needs to be lifted up by the lifting assembly to a position aligned with the upper transport assembly for recycling the empty frame, and then lowered to a position aligned with the lower transport assembly for loading the next PCB board frame, which makes the pushing plate assembly have a loading gap, thereby making it impossible for the PCB board feeding device to achieve continuous board loading.

It is only necessary to continuously place the batch stacked PCB board groups in the board storage cavity 102 to achieve continuous board loading of the board loading and suction device 10, thereby further improving the board loading efficiency of the board loading and suction device 10.

[0044] It should be noted that a switch door is provided on the rack 100, and the PCB board in the storage chamber 102 is replenished by opening or closing the switch door to ensure that the PCB board in the storage chamber 102 is replenished.

It is understood that the PCBs are transferred from the board storage chamber 102 to the conveyor assembly 200 by the suction plate 430 assembly 400, that is, the PCBs fall on the first belt conveyor 240 and the second belt conveyor 250. By driving the first belt conveyor 240 and the second belt conveyor 250, the PCBs can be transported to the next process to complete the loading operation of the PCBs.

[0046] like Figure 3 and Figure 5 As shown, in one embodiment, the transverse movement assembly 300 includes a transverse fixing frame 310, a transverse driving member 320, and a movable plate 330. The transverse fixing frame 310 is disposed on the frame 100, and the transverse driving member 320 is disposed on the transverse fixing frame 310. One end of the movable plate 330 is rotatably connected to the screw drive end of the transverse driving member 320 to drive the movable plate 330 to slide in connection with the transverse fixing frame 310. The other end of the movable plate 330 is connected to the fixed bracket 410. It can be understood that by driving the transverse driving member 320, the movable plate 330 rotates on the screw drive end of the transverse driving member 320, thereby driving the movable plate 330 to move transversely, thereby driving the suction plate 430 assembly 400 to move transversely.

[0047] like Figure 4 As shown, in one embodiment, the longitudinal movement assembly 500 includes a longitudinal drive member 510 and a movable support frame 520. The longitudinal drive member 510 is disposed within the frame 100, and the movable support frame 520 is located within the board storage chamber 102. The movable support frame 520 is rotatably connected to the screw drive end of the longitudinal drive member 510. It is understood that by driving the longitudinal drive member 510, the movable support frame 520 rotates on the screw drive end of the longitudinal drive member 510, thereby driving the movable support frame 520 to move longitudinally, that is, the PCB board assembly on the movable support frame 520 can be moved up and down within the board storage chamber 102, so that the suction plate 430 assembly 400 can contact the PCB boards.

[0048] like Figure 1 、 Figure 7 and Figure 8 As shown, in one embodiment, the board loading and suction device 10 further includes a material frame feeding assembly 600, which includes a first transmission frame 610, a third belt conveyor 620, and a fourth belt conveyor 630. The first transmission frame 610 is mounted on the frame 100, the third belt conveyor 620 is mounted on the side wall of one end of the first transmission frame 610, and the fourth belt conveyor 630 is mounted on the side wall of the other end of the first transmission frame 610. The third belt conveyor 620 and the fourth belt conveyor 630 are both used to convey the PCB board frame. It can be understood that the PCB board frame to be loaded is placed on the first transmission frame 610, and the third belt conveyor 620 and the fourth belt conveyor 630 are driven to drive the PCB board frame to move on the third belt conveyor 620 and the fourth belt conveyor 630.

[0049] like Figure 1 、 Figure 10 and Figure 11 As shown, in one embodiment, the upper plate suction device 10 also includes a material frame lifting assembly 700, and the material frame lifting assembly 700 includes a material frame lifting drive member 710, a second transmission frame 720, a fifth belt conveyor member 730 and a sixth belt conveyor member 740. The material frame lifting drive member 710 is arranged in the frame 100, and the second transmission frame 720 is rotatably connected to the screw drive end of the material frame lifting drive member 710. The fifth belt conveyor member 730 is installed on the side wall of one end of the second transmission frame 720, and the sixth belt conveyor member 740 is installed on the side wall of the other end of the second transmission frame 720. The fifth belt conveyor member 730 and the sixth belt conveyor member 740 are both used to transport the PCB board material frame. It can be understood that the PCB sheet material frame is transported to the second transmission frame 720 through the third belt conveyor 620 and the fourth belt conveyor 630, driving the material frame lifting drive member 710 to lift and lower, so as to drive the second transmission frame 720 to lift and lower, and during the lifting process, the PCB board in the PCB sheet material frame is pushed to realize the board loading operation, and after completing the board loading operation of a single PCB sheet material frame, the empty PCB sheet material frame is unloaded by driving the fifth belt conveyor 730 and the sixth belt conveyor 740, so that the board loading and suction device 10 can adapt to the working conditions of PCB sheet material frame loading, thereby greatly improving the adaptability of the board loading and suction device 10.

It can be understood that after completing the board loading operation of a single PCB board frame, the empty PCB board frame is transported to the third transmission frame 810 by overdriving the fifth belt conveyor 730 and the sixth belt conveyor 740. Then, by driving the seventh belt conveyor 820 and the eighth belt conveyor 830, the empty PCB board frames are accumulated on the third transmission frame 810 for unified recovery.

It can be understood that by driving the push plate driving member 910 to drive the displacement of the movable plate 330, thereby driving the displacement of the push rod 930, the PCB boards in the PCB board frame on the second transmission rack 720 during the lifting process are pushed one by one to the first belt conveyor 240 and the second belt conveyor 250, completing the loading of a single PCB board frame, so that the upper plate suction device 10 can adapt to the loading working conditions of the PCB board frame, further improving the adaptability of the upper plate suction device 10.

[0053] It should be noted that the present disclosure only protects the electrical connection relationship between each component and the control assembly. As for the control method of the control assembly, it belongs to the existing technology and is not within the protection scope of the present disclosure.

[0054] It should be noted that the above-mentioned driving member can be a cylinder driving member, an electric driving member, a belt driving member, or a screw driving member.

[0055] The present disclosure also provides a PCB-based board loading and suction device, including the PCB-based board loading and suction device described in any of the above embodiments.

The transverse moving assembly is driven to move transversely to drive the fixed bracket to move transversely, so that the suction plate is located above the board storage cavity, that is, the multiple suction nozzles are located above the PCB boards. The longitudinal moving assembly is then driven to move longitudinally so that the PCB boards in the board storage cavity can abut against the third ends of the multiple suction nozzles. The integrated air extraction and air supply assembly is driven to extract air from the multiple suction nozzles, so that negative pressure is formed inside the multiple suction nozzles, thereby being able to suck the PCB boards. The lateral moving component is driven to move laterally so that the suction plate is located above the conveying plate component, and then the suction plate lifting driving component is driven to lift and lower the suction plate to the conveying plate component, and the air suction and air supply integrated component is driven to supply air to the multiple suction nozzles, so that positive pressure is formed inside the multiple suction nozzles, so that the PCB board can be separated from the multiple suction nozzles and fall on the conveying end of the conveying plate component to complete the PCB board loading operation. It is only necessary to continuously place the batch stacked PCB board groups in the board storage cavity to realize continuous board loading of the board loading and suction equipment, thereby further improving the board loading efficiency of the board loading and suction equipment.

Then, drive the longitudinal moving component to move longitudinally so that the PCB board in the board storage cavity can abut against the third ends of the multiple suction nozzles, and drive the integrated air extraction and air supply component to extract air from the multiple suction nozzles to form negative pressure inside the multiple suction nozzles, so that the PCB board can be sucked. The moving assembly moves laterally to position the suction plate above the conveying plate assembly, and then drives the suction plate lifting drive to perform a lifting operation to lower the suction plate onto the conveying plate assembly, driving the integrated air extraction and air supply assembly to supply air to the multiple suction nozzles, so that positive pressure is formed inside the multiple suction nozzles, so that the PCB board can be separated from the multiple suction nozzles and fall onto the conveying end of the conveying plate assembly to complete the PCB board loading operation. It is only necessary to continuously place batches of stacked PCB boards in the storage chamber to achieve continuous loading of the board by the board loading and suction device, thereby further improving the loading efficiency of the board loading and suction device.
