Description

Technical Field

[0001] This utility model relates to the field of PCBA tray swivel machine technology, and in particular to a general PCBA tray swivel machine. Background Technology

[0002] PCBA tray placement machines are used for product placement during online board separation and automatic tray placement of PCBAs. There are various PCBA models, and one PCBA tray placement machine is required for each model. The machine includes a frame with a crossbeam. A vertical cylinder is mounted on the crossbeam. A slider is connected to the actuator of the cylinder, and a dual-shaft extension motor is connected to one side of the cylinder. The dual-shaft extension motor's shaft is vertical and has a hollow structure with open ends. The upper end of the shaft is sealed and rotatably connected to an air pipe, which connects to a vacuum pump. The lower end of the shaft is sealed and integrally connected to a suction nozzle. When the cylinder retracts, the suction nozzle moves downwards via the slider and the dual-shaft extension motor. When the dual-shaft extension motor starts, it rotates the suction nozzle via the shaft to reach the designated position. The vacuum pump then activates, allowing the suction nozzle to adsorb the PCBA. The only difference between these PCBA tray placement machines is the suction nozzle, leading to wasted manufacturing costs and time, and ultimately resulting in an accumulation of more PCBA tray placement machines. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a universal PCBA tray placement machine to solve the technical problem of waste of manufacturing cost and cycle time caused by having one PCBA tray placement machine for each type of PCBA.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A universal PCBA tray-stacking machine includes a frame with a crossbeam. A vertical cylinder is mounted on the crossbeam. A slider is connected to the actuator end of the cylinder. A dual-shaft extension motor located on one side of the cylinder is connected to the slider. The shaft of the dual-shaft extension motor is vertical and has a hollow structure with open ends. The upper end of the shaft is sealed and rotatably connected to an air pipe, which is connected to a vacuum machine. The machine also includes multiple suction nozzles adapted to various PCBA models. Each suction nozzle has a universal connector at its upper end, and each nozzle can be detachably and sealedly connected to the lower end of the shaft via its universal connector.

[0006] Furthermore, the universal connector is tubular, and the tubular universal connector is inserted into the lower end of the rotating shaft.

[0007] Furthermore, the lower end of the rotating shaft has a plurality of protrusions evenly spaced around its inner wall, and the outer wall of the universal connector has a plurality of recesses evenly spaced around its outer wall. The lower end of the rotating shaft and the universal connector are tightly inserted into the lower end of the rotating shaft through the universal connector, and the plurality of protrusions are locked into the plurality of recesses and connected.

[0008] Furthermore, a fastening ring is fitted onto the lower outer wall of the rotating shaft corresponding to multiple protrusions.

[0009] Furthermore, the universal connector is connected to the lower end of the shaft via a flange.

[0010] Furthermore, each nozzle includes multiple parallel vertical nozzle heads, the upper ends of which are vertically connected to a hollow adapter block, and the top surface of the hollow adapter block is vertically connected to a universal connector.

[0011] The beneficial effects of the utility model are:

[0012] This utility model provides a universal PCBA tray placement machine that only requires designing a dedicated suction nozzle for each PCBA model. These suction nozzles all have universal connectors at their upper ends. When placing products, simply take the corresponding suction nozzle, which is connected to the lower end of the tray placement machine's rotating shaft via the universal connector. This saves on the manufacturing cost and cycle time of the tray placement machine, and also reduces the storage of the PCBA tray placement machine.

[0013] The universal connector and the lower end of the shaft are connected by a plug-in joint for quick replacement.

[0014] The lower end of the shaft is tightly inserted into the lower end of the shaft through the universal connector, and multiple protrusions are locked into multiple concave holes to connect, realizing the plug-in connection while ensuring the sealing of the connection.

[0015] The lower end of the shaft has a fastening ring fitted around the outer wall corresponding to multiple protrusions, which further ensures the sealing of the connection between the lower end of the shaft and the universal connector.

[0016] A nozzle with multiple suction heads provides better adsorption performance for PCBA.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0025] Example 1

[0026] like Figure 1-4 As shown, a general-purpose PCBA tray-stacking machine includes a frame 1, a crossbeam 2 on the frame 1, and a vertical cylinder 3 on the crossbeam 2. A slider 4 is connected to the actuating end of the cylinder 3, and a dual-shaft extension motor 5 located on one side of the cylinder 3 is connected to the slider 4. The rotating shaft 6 of the dual-shaft extension motor 5 is vertical and has a hollow structure with openings at both ends. The upper end of the rotating shaft 6 is sealed and rotatably connected to an air pipe, which is connected to a vacuum machine. This structure is the existing structure of PCBA tray-stacking machines. The innovation of this embodiment is that the general-purpose PCBA tray-stacking machine also includes multiple suction nozzles 7, each adaptable to various PCBA models. Multiple nozzles 7 are available, and each nozzle 7 includes two parallel vertical suction heads 8. The upper ends of the two suction heads 8 are vertically connected to a hollow adapter block 9, and the top of the hollow adapter block 9 is vertically connected to a tubular universal connector 10. The two suction heads 8, the hollow adapter block 9, and the universal connector 10 are interconnected. Figure 4 As shown, the outer wall of the tubular universal connector 10 is provided with multiple recessed holes 11 evenly spaced around its circumference. The inner wall of the lower end of the rotating shaft of the dual-shaft motor 5 is provided with multiple protrusions 12 evenly spaced around its circumference. The universal connector 10 of each suction nozzle 7 can be tightly inserted into the lower end of the rotating shaft 6, and the multiple protrusions 12 are locked in the multiple recessed holes 11, realizing the insertion of the universal connector 10 of the suction nozzle 7 into the lower end of the rotating shaft 6 and ensuring a sealed connection between the universal connector 10 and the lower end of the rotating shaft 6. To further ensure the sealing effect of the connection between the universal connector 10 of the suction nozzle 7 and the rotating shaft 6, a rubber fastening ring 13 is fitted on the outer wall of the lower end of the rotating shaft 6 corresponding to the multiple protrusions 12. This tray-stacking machine only requires changing the suction nozzle 7 to place different models of PCBA, thereby saving the manufacturing cost and cycle of the tray-stacking machine and reducing the storage of PCBA tray-stacking machines. The universal connector 10 of the suction nozzle 7 is connected to the rotating shaft 6 of the dual-shaft motor 5 through insertion, making the replacement of the suction nozzle 7 quick.

[0027] Example 2

[0028] The difference from Embodiment 1 is that the structure of the suction nozzle 7 is different. The suction nozzle 7 has only one vertical suction head 8, and the upper end of the suction head 8 is directly connected to the universal connector 10. The lower end of the shaft 6 of the dual-shaft extension motor 5 is provided with a flange, and the upper end of the universal connector 10 of the suction nozzle 8 is also provided with a flange. The universal connector 10 and the shaft 6 are connected by two flanges, a sealing gasket between the flanges, and bolts.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
