Description

Technical Field

[0001] The present invention relates to the field of automatic processing technology, in particular to a buzzer wire bonding machine. Background Art

[0002] A buzzer is an integrated electronic sounder powered by DC voltage. It is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronics, telephones, and timers. The buzzer primarily consists of a housing, which holds the PCBA and coil. The two ends of the coil must be soldered to two solder points on the PCBA.

[0003] Currently, the soldering process for the two ends of the coil to the PCBA is as follows: a worker first manually holds the buzzer; then manually presses one end of the coil onto the corresponding solder point on the PCBA; then, using a spot welder, spot welds the wire end to the PCBA; then, manually presses the other end of the coil onto the corresponding solder point on the PCBA; and finally, spot welds the wire end to the PCBA. This soldering method requires manual positioning and wire management, resulting in a low level of automation and low efficiency. Furthermore, the buzzer is small, and manual positioning and wire management puts the worker in close proximity to the spot welder's soldering tip, posing a safety hazard. Summary of the Invention

[0040] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0041] See also Figures 1 to 11 In an embodiment of the present invention, a buzzer wire bonding machine includes:

[0042] The circulation mechanism 1 includes a turntable 11. A plurality of positioning fixtures 13 are arranged in a ring array on the top surface of the turntable 11 with its center as the center. A carrying plate 12 is provided above the turntable 11. The carrying plate 12 does not rotate with the turntable 11.

[0043] There are two wire bonding mechanisms 2, and the two wire bonding mechanisms 2 are sequentially distributed along the circumference of the turntable 11. The wire bonding mechanisms 2 include a wire clamping device 21 and a welding device 22. The wire clamping device 21 is disposed on the outside of the turntable 11, and the welding device 22 is disposed on the top surface of the carrier disc 12. The wire clamping device 21 and the welding device 22 are disposed opposite each other.

[0044] Among them, the wire clamping device 21 includes a three-way driving member 211 and a wire clamping air clamp 212. The wire clamping air clamp 212 is arranged on the three-way driving member 211. The three-way driving member 211 can drive the wire clamping air clamp 212 to move longitudinally, transversely and vertically. A guide rod 213 is passed through one of the clamping arms of the wire clamping air clamp 212. A floating block 214 is connected to the guide rod 213. A first spring 215 is provided on the outer sleeve of the guide rod 213. One end of the first spring 215 abuts against the clamping arm, and the other end of the first spring 215 abuts against the floating block 214. A first one-way driving member 216 is provided on the outside of the clamping arm. The first one-way driving member 216 is connected to the floating block 214 to drive the floating block 214 to approach or move away from the other clamping arm of the wire clamping air clamp 212.

[0045] In this embodiment, the positioning fixture 13 is used to carry the unsoldered buzzer, and the turntable 11 is used to drive the unsoldered buzzer to two wire welding mechanisms 2. The two wire welding mechanisms 2 are respectively used to weld the two wire ends of the buzzer; the lengths of the two wire ends of the buzzer are different before welding, one is a long wire end and the other is a short wire end. During the welding process, the long wire end of the buzzer is first clamped by the wire clamping device 21 of one of the wire welding mechanisms 2 and placed on the corresponding welding point, and then welded by the corresponding welding device 22. After the long wire end is welded, the turntable 11 drives the buzzer to move to another wire welding mechanism 2, and the wire clamping device 21 of the other wire welding mechanism 2 cooperates with the welding device 22 to weld the short wire end of the buzzer.

[0046] Specifically, during the welding process of the long wire head, the wire clamp 212 of one of the wire welding mechanisms 2 is driven by the three-way driving member 211 to move to one side of the buzzer. After the two clamping arms of the wire clamp 212 approach each other and clamp the long wire head and the short wire head of the buzzer, the wire clamp 212 moves in the direction away from the buzzer. During this process, due to the provision of the first spring 215, the guide rod 213 and the floating block 214, the wire clamp 212 flexibly clamps the long wire head and the short wire head of the buzzer to avoid tearing the long wire head and the short wire head off. When the wire clamp 212 retreats for a length greater than the length of the short wire head and less than the length of the long wire head, the short wire head breaks away from the wire clamp 212, and the wire clamp 2 12 stops moving, the first one-way driving member 216 starts to operate and presses against the floating block 214, canceling the flexible clamping of the long wire end, and finally, placing the long wire end on the corresponding welding point for subsequent wire welding work. While welding, the wire clamp 212 is pulled outward to break the excess wire end, and then reset. The turntable 11 drives the buzzer with the long wire end welded to another welding mechanism; in the process of welding the short wire end, the wire clamp 212 is driven by the three-way driving member 211 to clamp the short wire end of the buzzer and place it on the corresponding welding point, which is welded by the corresponding welding device 22. While welding, the wire clamp 212 is pulled outward to break the excess wire end, and then reset.

[0047] The buzzer wire bonding machine includes a machine platform 1 with a turntable 11 disposed on its top surface. A loading station, a first wire bonding station, a second wire bonding station, an inspection station, and an unloading station are sequentially arranged along the outer perimeter of the turntable 11. Two wire bonding mechanisms 2 are located at the first and second wire bonding stations, respectively. This allows for the placement of processing mechanisms for corresponding processes around the turntable 11, fully utilizing the space near the turntable 11 and reducing the required equipment footprint.

[0048] The buzzer wire bonding machine also includes a loading mechanism 4, which is arranged on the loading station. The loading mechanism 4 includes a loading air clamp 41, a loading tray 42, a first two-way drive 43 and a second one-way drive 44. The first two-way drive 43 is arranged above the turntable 11, and the loading air clamp 41 is arranged on the first two-way drive 43. The first two-way drive 43 can drive the loading air clamp 41 to move horizontally and vertically. The second one-way drive 44 is arranged below the first two-way drive 43. The loading tray 42 is arranged on the second one-way drive 44. The second one-way drive 44 can drive the loading tray 42 to move longitudinally. When in use, the staff will place the tray with unsoldered buzzers on the loading tray 42. During the loading process, the buzzers on the tray are transferred to the positioning fixture 13 by the loading air clamp 41 through the first two-way drive 43 and the second one-way drive 44, thereby completing the loading operation.

[0049] The buzzer wire bonding machine also includes a wire management mechanism 5, and there are two wire management mechanisms 5. The two wire management mechanisms 5 are both arranged on the top surface of the carrier plate 12. One wire management mechanism 5 is located between the feeding mechanism 4 and the adjacent wire bonding mechanism 2, and the other wire management mechanism 5 is located between the two wire bonding mechanisms 2. The wire management mechanism 5 includes a third one-way driving member 52 and a wire management air clamp 51. The wire management air clamp 51 is arranged on the third one-way driving member 52. The third one-way driving member 52 can drive the wire management air clamp 51 to move to approach or move away from the positioning fixture 13. After loading is completed, the turntable 11 drives the unwelded buzzer to move to the wire-managing mechanism 5, and the wire-managing air clamp 51 clamps the long wire end and the short wire end of the buzzer, and then, driven by the third one-way driving member 52, moves in the direction away from the positioning fixture 13, straightening the long wire end and the short wire end to facilitate the subsequent wire clamping device 21 to clamp the wire end. After straightening the long wire end and the short wire end, the wire-managing air clamp 51 releases the long wire end and the short wire end and resets, and the turntable 11 drives the unwelded buzzer to move to the next workstation.

[0050] The welding device 22 includes a fourth one-way driving member 221, a support plate 222, a movable rod 223, a second spring 224, a slider 225, a mounting bracket 226 and a welding head 227. The slider 225 and the fourth one-way driving member 221 are both arranged on the support plate 222. The fourth one-way driving member 221 is connected to the slider 225 to drive the slider 225 to move vertically. The starting end of the mounting bracket 226 is slidably set on the slider 225. The end of the mounting bracket 226 extends to the top of the positioning fixture 13. The welding head 227 is set at the end of the mounting bracket 226. A boss 228 is formed on the top of the slider 225. The movable rod 223 is passed through the boss 228. The lower end of the movable rod 223 is connected to the mounting bracket 226. The second spring 224 is sleeved on the movable rod 223. One end of the second spring 224 abuts against the mounting bracket 226, and the other end of the second spring 224 abuts against the boss 228. After the wire end is placed on the corresponding welding point, the welding head 227 moves under the drive of the fourth one-way driving member 221 to weld the wire end to the corresponding welding point. After welding, the welding head 227 is reset, and the buzzer after welding is driven by the turntable 11 to move to the next workstation; it should also be noted that during welding, the setting of the movable rod 223 and the second spring 224 can avoid hard contact between the welding head 227 and the buzzer, which may cause damage to the buzzer, and can also ensure that the welding head 227 always maintains contact with the welding point of the buzzer to ensure the welding effect.

[0051] The wire bonding mechanism 2 further includes a cleaning device 23, which is disposed on one side of the wire clamping device 21. The cleaning device 23 includes a second bidirectional driving member 231 and a cleaning box 232. The cleaning box 232 is filled with solder paste and is disposed on the second bidirectional driving member 231. The second bidirectional driving member 231 can drive the cleaning box 232 to move closer to or away from the bonding head 227. During use, the cleaning box 232 can be moved to the bonding head 227 by the second bidirectional driving member 231, so that the solder paste in the cleaning box 232 is applied to the bonding head 227 to remove impurities on the surface of the bonding head 227.

[0052] The buzzer wire bonding machine also includes a detection mechanism 6, which is arranged on the detection station. The detection mechanism 6 includes a fifth one-way driving member 61, a detection block 62 and a detection needle 63. The detection block 62 is arranged on the fifth one-way driving member 61, and the fifth one-way driving member 61 can drive the detection block 62 to move vertically. There are two detection needles 63, and both detection needles 63 are arranged on the detection block 62. After welding, the turntable 11 drives the welded buzzer to move to the detection mechanism 6. The detection block 62 moves under the drive of the fifth one-way driving member 61 so that the two detection needles 63 contact the two welding points to detect whether the welding points are conductive.

[0053] The buzzer wire bonding machine also includes a blanking mechanism 7, which is arranged on the blanking station. The blanking mechanism 7 includes a blanking air clamp 71, a blanking tray 72, a material return rod 73, a waste box 74, a third bidirectional driving member 75, a sixth unidirectional driving member 77 and a seventh unidirectional driving member 76. The material return rod 73 is arranged below the turntable 11. The turntable 11 and the positioning fixture 13 are both provided with a through hole for the material return rod 73 to extend into.

When in use, the staff puts the empty material tray on the material discharge tray 72. During the material discharge process, the third two-way driving member 75, the sixth one-way driving member 77 and the seventh one-way driving member 76 drive the material return rod 73 to lift the buzzer in the positioning fixture 13, and then the material discharge air clamp 71 transfers the qualified buzzers on the positioning fixture 13 to the material tray, and places the unqualified buzzers in the waste bin 74, thereby completing the material discharge operation.

[0054] The top surfaces of both the loading tray 42 and the unloading tray 72 are provided with a plurality of placement slots, each with a notch 45 in one corner. An L-shaped positioning plate 46 is disposed within the notch 45. An eighth one-way drive member 47 is connected to the bottom surface of the L-shaped positioning plate 46. The eighth one-way drive member 47 can drive the L-shaped positioning plate 46 into or out of the notch 45. When placing a tray, the eighth one-way drive member 47 drives the L-shaped positioning plate 46 out of the notch 45. The tray is then placed into the placement slot by a staff member. Finally, the eighth one-way drive member 47 drives the L-shaped positioning plate 46 into the notch 45, thereby securing the tray.

[0055] In order to ensure the wire clamping effect, a limiting rod 217 is provided on the inner side of the floating block 214 , and the end of the limiting rod 217 is passed through the other clamping arm of the wire clamping air clamp 212 .
