[0049] The gold fingers on the circuit board (PCB) are prone to oxidation, tin contamination, and contamination during the SMT process segment production process, so the circuit board will use high-temperature adhesive tape to wrap the gold fingers during production. The gold fingers of some circuit boards are distributed on multiple sides of the circuit board, and after the adhesive is pasted, the adhesive tape on multiple sides of the circuit board needs to be rolled in turn. In related technologies, the rolling device usually rolls on one side of the circuit board first, and then moves to the other side or several other sides of the circuit board for rolling, and such repeated movement results in low rolling efficiency. In addition, the rolling device in related technologies does not have a supporting structure, so that during the adhesive pasting process before rolling, the circuit board usually cannot be effectively supported, affecting the adhesive pasting efficiency.

[0066] As shown in Figures 4 to 6 , the adhesive application assembly 62 includes a base 621, a blocking piece 622, an adhesive tape guiding assembly 63, an adhesive tape cutting assembly 64 and an adhesive tape rolling assembly 65. The base 621 is slidingly arranged on the adhesive application multi-axis track 61, and the blocking piece 622, the adhesive tape guiding assembly 63, the adhesive tape cutting assembly 64 and the adhesive tape rolling assembly 65 are arranged on the base 621. The blocking piece 622 can be raised and lowered and is used to block the circuit board 100 on the conveying belt 52 at the adhesive application station. The blocking piece 622 includes a blocking cylinder 623 and a blocking block 624. The blocking cylinder 623 drives the blocking block 624 to descend to block the circuit board 100 at the adhesive application station, and the blocking cylinder 623 is fixed to the base 621. Before the circuit board 100 reaches the adhesive application station, the blocking cylinder 623 first drives the blocking block 624 to descend to block the incoming circuit board 100.

[0067] As shown in Figure 5 , Figure 6As shown, the adhesive tape guiding assembly 63 is used to guide the adhesive tape and adhere to the gold fingers on the circuit board 100. The adhesive tape guiding assembly 63 comprises an adhesive tape roll mounting portion 631, a driving release wheel 632, a release motor 633, a first guide wheel 634, a first guide wheel moving member 635, a counterweight wheel 636, a release detecting member 637, a second guide wheel 638, a rotating plate 639, a third guide wheel 640, a fourth guide wheel 641 and an adhesive tape adhering driving member 642. The adhesive tape roll mounting portion 631, the second guide wheel 638, the release detecting member 637 and the adhesive tape adhering driving member 642 are arranged on the base 621.

[0068] As shown in Figure 5 , Figure 6 , the driving release wheel 632 is rotatably arranged on the base 621 and connected to the release motor 633. The first guide wheel 634 is rotatably arranged on the base 621 and abuts against the driving release wheel 632. The first guide wheel moving member 635 is arranged on the base 621 and used to adjust the distance between the first guide wheel 634 and the driving release wheel 632. For example, the driving release wheel 632 and the first guide wheel 634 are arranged horizontally side by side. The first guide wheel moving member 635 comprises a moving groove 643, a moving seat 644, a pull rod 645 and a locking member 646. The moving groove 643 is formed in the base 621. The first guide wheel 634 is rotatably arranged on the moving seat 644. The moving seat 644 is horizontally slidably arranged in the moving groove 643. One end of the pull rod 645 is connected to the moving seat 644 and the other end is connected to the locking member 646. By pulling the pull rod 645, the first guide wheel 634 can be horizontally moved, so that the adhesive tape can pass between the driving release wheel 632 and the first guide wheel 634. After adjusting the position of the first guide wheel 634, the position of the pull rod 645, the moving seat 644 and the first guide wheel 634 can be locked by the locking member 646. The adhesive tape passes between the driving release wheel 632 and the first guide wheel 634. The driving release wheel 632 is rotated by the release motor 633. The friction between the driving release wheel 632 and the first guide wheel 634 drives the adhesive tape to move, so that the adhesive tape is pulled out and released.

[0069] As shown in Figure 5 , Figure 6The counterweight wheel 636 is slidably arranged on the base 621, and a release detection member 637 is arranged to detect the position of the counterweight wheel 636 and connected to the release motor 633. The base 621 includes a guide column 625 and a sliding block 626 slidably arranged on the guide column 625, and the counterweight wheel 636 is rotatably arranged on the sliding block 626. The sliding block 626 is formed with a sensing block 627, and one end of the sensing block 627 corresponds to the release detection member 637. The release detection member 637 can be a sensor, and the release motor 633 can be a stepping motor. During the adhesive taping process, the adhesive tape is pulled out, and the counterweight wheel 636 will rise along the guide column 625. When the counterweight wheel 636 rises to a certain height, the release detection member 637 cannot detect the counterweight wheel 636, triggering the release motor 633 to rotate the driving release wheel 632 and the first guide wheel 634 again to release the adhesive tape.

[0070] As shown in Figure 5 , Figure 7 , one end of the rotating plate 639 is rotatably arranged on the base 621, and the other end is hingedly connected to the adhesive taping driving member 642.

The guide groove assembly 66 includes a first guide seat 661, a second guide seat 662, and a third guide seat 663 fixed to the rotating plate 639. The lower part of the third guide seat 663 is inserted into the first guide seat 661. The first guide seat 661, the second guide seat 662, and the third guide seat 663 form a guide groove 664 for the adhesive tape therebetween. The guide groove 664 is connected between the third guide wheel 640 and the fourth guide wheel 641, and the width of the guide groove 664 can be adjusted by moving the third guide seat 663 on the first guide seat 661.

[0071] As shown in Figure 7 , the bottom of the third guide seat 663 abuts against the second guide seat 662, and the bottom of the first guide seat 661 has a gap with the second guide seat 662 to form the guide groove 664. One end of the first guide seat 661 is formed with a first arc surface 665 for supporting the third guide wheel 640, and one end of the second guide seat 662 is formed with a second arc surface 666 for supporting the fourth guide wheel 641. The guide groove assembly 66 further includes a sleeve column 667 and a fastening screw 668. The upper part of the third guide seat 663 is formed with an expansion slot 669 extending into the third guide seat 663 and formed with a sleeve slot 670. The sleeve slot 670 is sleeved on the sleeve column 667, and the fastening screw 668 is threadedly connected to the third guide seat 663 and pressed against the sleeve column 667.

[0072] As shown in Figure 7As shown, one end of the insert post 667 is fixed to the rotating plate 639, and one end of the third guide seat 663 is inserted into the third guide wheel 640, with the tape passing through the third guide seat 663 and the rotating plate 639 on the third guide wheel 640. When the width of the tape wound on the guide groove 664 and the third guide wheel 640 needs to be adjusted according to the width of the tape, loosen the fastening screw 668, then move the third guide seat 663 back and forth for adjustment. After adjustment, tighten the fastening screw 668 again.

[0073] like Figure 5 As shown, the tape roll mounting part 631, the active release wheel 632, the second guide wheel 638, the counterweight wheel 636, and the rotating plate 639 are arranged sequentially from top to bottom. The tape roll is mounted on the tape roll mounting part 631. The tape on the tape roll passes sequentially between the active release wheel 632 and the first guide wheel 634, the counterweight wheel 636, the second guide wheel 638, the third guide wheel 640, the guide groove 664, and the fourth guide wheel 641. The tape head extends under the fourth guide wheel 641.

[0074] like Figure 6 As shown, the tape cutting assembly 64 is used to cut tape. The tape cutting assembly 64 includes a cutting lifting cylinder 647, a cutting cylinder 648, and a cutting blade 649. The cutting cylinder 648 drives the cutting blade 649 to move to achieve the cutting action. The cutting cylinder 648 is connected to the piston shaft of the cutting lifting cylinder 647, and the cutting lifting cylinder 647 is fixed to the base 621.

[0075] like Figure 5 As shown, the tape rolling assembly 65 is used to roll and flatten the tape on the cut gold fingers.

The rolling cylinder 651 drives the rolling roller 652 to move to the tape on the gold fingers for rolling and flattening. The rolling cylinder 651 is fixed to the base 621. A protective cover (not shown) may be provided on the tape rolling assembly 65, the adhesive application drive 642, and the rotating plate 639. The protective cover is fixed to the base 621.

[0076] like Figure 1 As shown, the circuit board adhesive application equipment also includes a frame 7 and a human-machine interface module 8 mounted on the frame 7. The human-machine interface module 8 includes a control unit (not shown), a flow channel unit 5, an adhesive application unit 6, and an adhesive application support roller device for the circuit board, all housed within the frame 7 and connected to the human-machine interface module 8. The control unit controls the coordination between various processes such as conveying, adhesive application, and rolling of the circuit board 100. Before adhesive application, the number of adhesive applications and rolling cycles for each side of the circuit board 100 are set on the human-machine interface module 8. The duration of each operation of the release motor 633 can be set on the human-machine interface module 8.

[0077] When the adhesive tape is attached, the adhesive tape driving member 642 drives the rotating plate 639 to rotate downward, and the cutting lifting cylinder 647 drives the cutting knife 649 to descend. The fourth guide wheel 641 descends to press the adhesive tape head against the gold fingers of the circuit board 100. The adhesive tape assembly 62 moves along the adhesive tape multi-axis track 61 to achieve the attachment of the adhesive tape. After the attachment, the adhesive tape driving member 642 drives the rotating plate 639 to rotate upward and reset, and the rolling cylinder 651 drives the rolling wheel 652 to descend and press against the circuit board 100. The adhesive tape is pulled up, and the cutting cylinder 648 drives the cutting knife 649 to move and cut the adhesive tape. The cut adhesive tape falls and covers the gold fingers due to gravity, but is not attached. At this time, the adhesive tape assembly 62 moves along the adhesive tape multi-axis track 61 to achieve the rolling of the adhesive tape by the rolling wheel 652 until it is flat and attached. After the rolling is completed, the rolling cylinder 651 drives the rolling wheel 652 to ascend and reset. The entire adhesive tape assembly 62 moves along the adhesive tape multi-axis track 61 to reset or move to the gold fingers on the other side of the circuit board 100 to be attached.

[0078] Embodiment Three

[0079] The present application provides an adhesive tape attaching method for a circuit board, which is applied to the adhesive tape attaching device of the circuit board of embodiment two and the circuit board 100 with gold fingers on opposite sides. In this embodiment, the adhesive tape is attached to the circuit board 100 with gold fingers on opposite sides. As shown in FIG. 6, the method comprises the following steps: Figure 10

[0080] S1: The blocking member 622 descends to block the circuit board 100 conveyed on the conveying belt 52 at the adhesive tape attaching station. The conveying belt 52 stops running. The blocking member 622 ascends to reset. The adhesive tape assembly 62 moves along the adhesive tape multi-axis track 61 to the gold fingers on the side of the circuit board 100 to be attached.

[0081] Specifically, after the blocking member 622 descends to block the circuit board 100 conveyed on the conveying belt 52 at the adhesive tape attaching station, the conveying belt 52 stops running. The width adjusting assembly acts to clamp the two ends of the circuit board 100 between the fixed track 511 and the moving track 512 to position the circuit board 100. The circuit board clamping assembly 54 acts to clamp the circuit board 100 between the conveying belt 52 and the clamping block 541 to further position the circuit board 100. Then the blocking member 622 ascends to reset. The adhesive tape assembly 62 moves along the adhesive tape multi-axis track 61 to the gold fingers on the side of the circuit board 100 to be attached.

[0082] S2: The support rolling unit 1 corresponding to the gold fingers to be attached acts. The support driving part 21 of the support assembly 2 of the support rolling unit 1 drives the support part 22 to ascend to support the side of the circuit board 100 to be attached.

[0083] S3: The adhesive tape guiding assembly 63 guides the adhesive tape and moves along the adhesive tape multi-axis track 61 to attach the adhesive tape to the gold fingers. After the attachment, the adhesive tape guiding assembly 63 resets. ​

[0084] S4: The adhesive tape cutting assembly 64 cuts the adhesive tape, and after cutting, the adhesive tape cutting assembly 64 resets, and the adhesive tape rolling assembly 65 rolls and flattens the adhesive tape on the gold finger after cutting, and after rolling and flattening, the adhesive tape rolling assembly 65 resets.

[0085] S5: The adhesive assembly 62 moves to the above of the gold finger on the other side edge of the circuit board 100 to be pasted with adhesive along the adhesive multi-axis track 61, and repeats steps S2-S4 to paste and roll and flatten the adhesive on the gold finger on the other side edge of the circuit board 100 to be pasted with adhesive, and at the same time, the support assembly 2 corresponding to the gold finger pasted with adhesive resets, and the lifting driving part 33 and the rolling driving part 34 of the rolling assembly 3 drive the upper roller 31 and the lower roller 32 to move and clamp the corresponding side edge of the circuit board 100 in the upper roller 31 and the lower roller 32 to roll and flatten the adhesive, and after rolling and flattening, the rolling assembly 3 resets to complete the pasting and rolling of the adhesive on the gold finger on one side of the circuit board 100.

[0086] That is, the adhesive assembly 62 pastes and rolls the adhesive in this round, and the rolling assembly 3 corresponding to the pasted adhesive of the last round performs the rolling action. In this way, while the gold finger on one side of the circuit board 100 is pasted with adhesive, the rolling assembly 3 corresponding to the gold finger on the other side of the circuit board 100 performs the rolling action on the pasted adhesive. The pasting and rolling actions on different sides are performed at the same time, which improves the pasting efficiency of the circuit board 100.

[0087] S6: The adhesive assembly 62 moves to reset along the adhesive multi-axis track 61, and at the same time, the support assembly 2 corresponding to the gold finger pasted with adhesive resets, and the lifting driving part 33 and the rolling driving part 34 of the rolling assembly 3 drive the upper roller 31 and the lower roller 32 to move and clamp the corresponding side edge of the circuit board 100 in the upper roller 31 and the lower roller 32 to roll and flatten the adhesive, and after rolling and flattening, the rolling assembly 3 resets to complete the pasting and rolling of the adhesive on the gold finger on the other side of the circuit board 100.

[0088] S7: The conveying belt 52 runs again to convey the circuit board 100 pasted with adhesive away from the adhesive pasting station.
