Description

Technical Field

[0001] The utility model relates to the field of board splitting equipment, in particular to a feeding device of a board splitting machine. Background Art

[0002] PCBs are the electrical connections for electronic components. In industry, to achieve mass production, multiple PCBs are typically fabricated on a single board. Depaneling machines are typically referred to as PCB depanelers, or circuit board depanelers. Depaneling machines are widely used in the electronics manufacturing industry. Because traditional manual folding methods generate significant stress, severely impacting product quality, manual folding has largely been replaced by machine depaneling.

[0003] Currently, a common solution is to use a PCB depaneling machine to mill each PCB. To prevent the PCB from shifting or warping during milling and to ensure the processing quality of the PCB, a conveyor line is used to transport the PCB to be milled to a positioning fixture. The positioning fixture is then used to position the PCB before milling. After milling, the PCB is output using a conveyor line. Therefore, the conveyor line is usually set very long, which results in a bulky structure of the PCB depaneling machine, which is not conducive to transportation and layout.

[0004] An existing patent (publication number: CN 108834316 A, announcement date: November 16, 2018) discloses a fully automatic PCB depaneling machine. The machine utilizes a loading and conveying mechanism, which is sequentially arranged on a machine frame, for transferring the PCB from the preceding station to the loading station; a loading mechanism for moving the PCB from the loading station to the depaneling station; a depaneling mechanism; a depaneling mechanism for moving the PCB from the depaneling station to the unloading station; and a depaneling mechanism for discharging the processed PCB. These mechanisms work in coordination with each other, achieving fully automatic flow production of the PCB from alignment and transfer to loading and depaneling, and finally to unloading and discharging. The machine boasts high work efficiency, good depaneling quality, a high yield rate, a high degree of automation, and low labor costs.

[0005] In the above scheme, the PCB boards are transported piece by piece to the bottom of the loading mechanism through the loading and conveying mechanism, and the PCB boards are then sent into the depaneling mechanism through the loading and conveying mechanism. However, the PCB boards are generally stacked together before depaneling. The above equipment needs to place the PCB boards to be depaneled one by one on the loading and conveying mechanism by mechanical automatic or manual methods. The mechanical automatic placement of PCB boards will make the whole machine bulky, and manual placement has problems such as low precision, slow efficiency, and high labor cost. Therefore, it is necessary to design an automatic loading device in the depaneling machine that can be used for stacked PCB boards of different thicknesses. Utility Model Content

[0036] like Figure 1-6 As shown, a loading device of a board splitter of the present invention comprises a frame 1, on which a workbench 2 is fixedly mounted;

[0037] A plate feeding mechanism 3 is fixedly installed on the workbench 2, a front placement table 4 is fixedly installed on the front side of the frame 1, a plate 5 is placed on the front placement table 4, and an adaptive plate taking mechanism 6 is installed at the front end of the workbench 2. The adaptive plate taking mechanism 6 transports the plate 5 on the placement table to the plate feeding mechanism 3;

[0038] The adaptive plate-taking mechanism 6 includes a Y-axis conveying mechanism 61, a slide 62 and an adaptive adsorption machine 63. The Y-axis conveying mechanism 61 drives the slide 62 to slide above the front placement table 4 and the plate-feeding mechanism 3. The adaptive adsorption machine 63 is installed on the slide 62.

[0039] The principle is: use the adaptive adsorption machine 63 to absorb the PCB sheet 5 to be processed on the front placement table 4, then use the Y-axis conveyor to transport it to the board feeding mechanism 3, and finally use the board feeding mechanism 3 to send it to the board separation station of the board separation machine for automatic board separation operation, thereby realizing automatic board separation. The adaptive adsorption machine 63 can adapt to PCB sheets 5 of different thicknesses for loading and conveying, which is convenient for the automated operation of the board separation equipment.

[0040] Further: the adaptive adsorption machine 63 includes a top plate 631, a lifting cylinder 632, a cross bar 633 and a plurality of lifting rods 634, the top plate 631 is located above the slide 62, and the four ends of the bottom side of the top plate 631 are fixedly installed with support rods 7, the bottom end of the support rod 7 is fixedly installed on the slide 62, the lifting cylinder 632 is fixedly installed on the top plate 631, the telescopic rod of the lifting cylinder 632 passes through the top plate 631 and drives the cross bar 633 to move up and down, a plurality of first guide sleeves 8 are fixedly installed on the slide, and a plurality of lifting rods 634 are slidably fitted in the plurality of first guide sleeves 8 in a one-to-one correspondence, the upper ends of two adjacent lifting rods 634 are fixedly installed with top connecting rods 9, and the top connecting rods 9 are arranged above the cross bar 633, and the lower ends of the lifting rods 634 are fixedly installed with a suction cup assembly 10;

[0041] The principle is as follows: when the lifting cylinder 632 drives the cross bar 633 to descend, the lifting rod 634 will descend with its own weight. When the suction cup assembly 10 at the lower end of the lifting rod 634 falls on the sheet 5 stacked on the front placement table 4, the suction cup assembly 10 will absorb the top sheet 5 by vacuuming, and then the lifting cylinder 632 is used to drive the cross bar 633 to rise. When the cross bar 633 rises to a certain position, the cross bar 633 will lift the lifting rod 634 through the top connecting rod 9, and then lift the top sheet 5. Since the lifting cylinder 632 does not directly drive the lifting rod 634 to move up and down, the lifting rod 634 is lowered by its own weight, so it can be suitable for sheets 5 of different stacking thicknesses, realizing adaptive sheet taking operation, and finally the Y-axis conveying mechanism 61 is used to convey it to the top of the sheet feeding mechanism 3, and the sheet 5 is placed on the sheet feeding mechanism 3 by breaking the vacuum;

[0042] Each set of suction cup assemblies 10 of the adaptive adsorption machine 63 uses its own gravity to achieve independent descent, and can adapt to PCB boards with different stacking thicknesses and unevenness.

[0043] Furthermore: at least two vertical rods 25 are fixedly installed between the slide 62 and the top plate 631, and at least two second guide sleeves 26 are fixedly installed on the cross bar 633. The vertical rods 25 are slidably fitted in the second guide sleeves 26 in a one-to-one correspondence; this enables the cross bar 633 to play a role in stable lifting and sliding.

[0044] Further: the suction cup assembly 10 includes a bottom connecting rod 101, two suction cup adjustment rods 102, two suction cup bolts 103 and two positioning suction cups 104, the bottom connecting rod 101 is fixedly mounted on the bottom ends of two adjacent lifting rods 634, the bottom connecting rod 101 is located below the slide 62, the two suction cup adjustment rods 102 are fixedly mounted on the bottom side of the bottom connecting rod 101, the suction cup bolts 103 are fixedly mounted on the suction cup adjustment rods 102 in a one-to-one correspondence, and the positioning suction cup 104 is fixedly mounted on the bottom ends of the suction cup bolts 103;

[0045] The principle is: the setting of the bottom connecting rod 101 can enhance the stability between the two adjacent lifting rods 634, ensuring that the lifting rod 634 can be stably lifted and lowered on the first guide sleeve 8 of the slide 62, and the angle and position of the suction cup bolt 103 can be adjusted by the suction cup adjustment rod 102 at the bottom, so that it can be suitable for sheets 5 of different widths.

[0046] Furthermore: a transverse groove 11 is formed in the middle of the suction cup adjustment rod 102, and a first positioning bolt 22 is installed in the transverse groove 11. The suction cup adjustment rod 102 is locked on the bottom side of the bottom connecting rod 101 by the first positioning bolt 22 passing through the transverse groove 11; the first positioning bolt 22 can slide in the transverse groove 11 before locking, thereby adjusting its locking position, which is convenient for adjusting the position of the suction cup bolt 103.

The slide 62 is fixedly installed on the first slider 613 of the two Y-axis conveying mechanisms 61; after removing the top side sheet 5 on the front placement table 4, the slide 62 can be driven by the first belt conveyors 612 on the left and right sides to allow the sheet 5 to move to the top of the plate feeding mechanism 3, and its conveying stability is higher.

[0048] Furthermore: a first servo motor 12 is fixedly installed on the side frame 611 of one of the Y-axis conveying mechanisms 61, and a first driving shaft 13 is connected between the first belt conveyors 612 of the two Y-axis conveying mechanisms 61. The first servo motor 12 drives the two first belt conveyors 612 to operate synchronously through the first driving shaft 13; the first driving shaft 13 can be used to make the first belt conveyors 612 on both sides operate synchronously, thereby ensuring the stability of the conveyed sheet material 5.

[0049] Furthermore, four horizontal slides 14 are formed on the front placing table 4, and two horizontal rods 15 are fixedly installed on the bottom side of the front placing table 4. A second slider 16 is slidably installed on the horizontal rod 15, and a connecting plate 17 is fixedly installed between the two adjacent second sliders 16 in front and behind.

A vertical rod 19 is fixedly installed on the second slider 16, and the vertical rods 19 are slidably installed in the horizontal slide grooves 14 one by one; it can act on the adaptive plate length positioning adjustment, because the vertical rods 19 are fixed on the second slider 16 one by one, and the second slider 16 can also be driven by the second belt conveyor 18. Under the action of the belt, when one of the vertical rods 19 moves, it can drive the other three vertical rods 19 to move together, and then drive the vertical rods 19 on both sides to clamp the sheet material 5. The second belt conveyor 18 can be used for automatic width adaptation adjustment, which is convenient for processing sheets 5 of different widths.

[0050] Furthermore: the plate feeding mechanism 3 includes a base 31, several third belt conveyors 32, a second servo motor 33 and a second driving shaft 34. The base 31 is installed on the workbench 2 in a lifting and sliding manner. Several third belt conveyors 32 are fixedly installed on the base 31. The second servo motor 33 is installed on the workbench 2. The second servo motor 33 drives several third belt conveyors 32 to operate synchronously through the second driving shaft 34. The adaptive plate taking mechanism 6 transports the plate material 5 on the placement table to the several third belt conveyors 32 of the plate feeding mechanism 3; several third belt conveyors 32 can simultaneously support the plate material 5 for transportation. The setting of the second driving shaft 34 can allow several third belt conveyors 32 to operate synchronously, thereby realizing stable transportation of the plate material 5.

[0051] Furthermore, a lifting unit 24 is fixedly installed on the bottom side of the workbench 2, and the lifting unit 24 drives the base 31 to move up and down.

[0052] Furthermore: the third belt conveyor 32 includes a positioning frame 321, a driving pulley 322, a driven pulley 323, a transmission belt 324 and two tensioning mechanisms 325.

The driving pulley 322 and the driven pulley 323 are rotatably mounted in the two tensioning mechanisms 325 in a one-to-one manner. The transmission belt 324 is mounted between the driving pulley 322 and the driven pulley 323. The second driving shaft 34 is passed through and mounted on the driving pulleys 322 of several third belt conveyors 32. The second driving shaft 34 drives several driving pulleys 322 to operate synchronously; the transmission belt 324 can be tensioned by the tensioning mechanisms 325 at the front and rear ends, so that it can be stably fitted between the driving pulley 322 and the driven pulley 323, thereby ensuring the stable transmission of the sheet material 5 on several third belt conveyors 32.

[0053] Furthermore, the second servo motor 33 is fixedly installed between the positioning frames 321 of two adjacent second belt conveyors 32 .

[0054] Furthermore, the tensioning mechanism 325 includes two side plates 3251, two second positioning bolts 3252, two adjusting bolts 3253 and two positioning blocks 3254. Two sliding adjustment slots 20 are formed at the front and rear ends of the positioning frame 321. The positioning frame 321 is arranged between the two side plates 3251. The side plates 3251 and the positioning frame 321 are locked by the second positioning bolts 3252 passing through the sliding adjustment slots 20. The positioning block 3254 is fixedly installed on the positioning frame 321. A threaded hole 21 is formed on the positioning block 3254. The adjusting bolt 3253 is screwed and installed in the threaded hole 21. One end of the adjusting bolt 3253 is set against the side plate 3251.

[0055] The principle is as follows: a sliding adjustment groove 20 is set on the positioning frame 321, and the second positioning bolt 3252 can slide in the sliding adjustment groove 20, so that the transmission belt 324 is tightly fitted between the active pulley 322 and the driven pulley 323, and then the second positioning bolt 3252 is used to lock the side plate 3251 for positioning, and the adjusting bolt 3253 is spirally fitted into the threaded hole 21 of the positioning block 3254. At the same time, one end of the adjusting bolt 3253 presses against the side plate 3251 to lock the position of the transmission belt 324 after tensioning, ensuring that the transmission belt 324 will not loosen by itself. At the same time, when the transmission belt 324 needs to be replaced, it can be no longer tensioned by loosening the adjusting bolt 3253 and the second positioning bolt 3252, thereby facilitating the replacement of the transmission belt 324.
