Description

Technical Field

[0001] This invention relates to the field of automated processing technology, and in particular to a buzzer wire bonding machine. Background Technology

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

[0003] Currently, the soldering process between the two ends of the coil and the PCBA is as follows: The worker first manually holds the buzzer; then manually presses one end of the coil onto the corresponding solder point on the PCBA; next, a spot welding machine is used to spot weld the coil end to the PCBA; then, the worker manually presses the other end of the coil onto the corresponding solder point on the PCBA; finally, spot welding is used to spot weld the coil end to the PCBA. This soldering method requires manual positioning and wire arrangement, resulting in low automation and low work efficiency. Furthermore, the buzzer is small, and manual positioning and wire arrangement place the worker's body close to the welding head of the spot welding machine, posing a safety hazard.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-11 In this embodiment of the invention, a buzzer wire bonding machine includes:

[0042] The circulation mechanism 1 includes a turntable 11. Multiple positioning fixtures 13 are arranged in a ring array on the top surface of the turntable 11 with its center as the center. A support plate 12 is provided above the turntable 11. The support 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 distributed sequentially along the circumference of the turntable 11. The wire bonding mechanism 2 includes a wire clamping device 21 and a welding device 22. The wire clamping device 21 is located on the outside of the turntable 11, and the welding device 22 is located on the top surface of the support plate 12. The wire clamping device 21 and the welding device 22 are arranged opposite to each other.

[0044] The wire clamping device 21 includes a three-way drive member 211 and a wire clamping air clamp 212. The wire clamping air clamp 212 is mounted on the three-way drive member 211, which can drive the wire clamping air clamp 212 to move longitudinally, laterally, and vertically. A guide rod 213 is mounted on 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 mounted 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 drive member 216 is mounted on the outer side of the clamping arm. The first one-way drive member 216 is connected to the floating block 214 to drive the floating block 214 to move closer to or 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 unwelded buzzer, and the turntable 11 is used to move the unwelded buzzer to the two wire bonding mechanisms 2. The two wire bonding mechanisms 2 are used to bond the two wire ends of the buzzer respectively. Before welding, the two wire ends of the buzzer are of different lengths, one is a long wire end and the other is a short wire end. During the welding process, the wire clamping device 21 of one of the wire bonding mechanisms 2 first clamps the long wire end of the buzzer and places it on the corresponding welding point. Then, the corresponding welding device 22 welds it. After the long wire end is welded, the turntable 11 moves the buzzer to the other wire bonding mechanism 2, where the wire clamping device 21 and the welding device 22 of the other wire bonding mechanism 2 cooperate to weld the short wire end of the buzzer.

[0046] Specifically, during the wire bonding process of the long wire end, the wire clamping air clamp 212 of one of the bonding mechanisms 2 moves to one side of the buzzer under the drive of the three-way drive component 211. After the two clamping arms of the wire clamping air clamp 212 approach each other and clamp the long and short wire ends of the buzzer, the wire clamping air clamp 212 moves away from the buzzer. During this process, due to the setting of the first spring 215, guide rod 213 and floating block 214, the wire clamping air clamp 212 flexibly clamps the long and short wire ends of the buzzer to avoid tearing them. When the retraction length of the wire clamping air clamp 212 is greater than the length of the short wire end but less than the length of the long wire end, the short wire end is released from the wire clamping air clamp 212. 12. Stop moving. The first unidirectional drive component 216 starts operating and presses against the floating block 214, canceling the flexible clamping of the long wire end. Finally, the long wire end is placed on the corresponding solder point for subsequent wire welding. While welding, the wire clamping air clamp 212 pulls outward to break off the excess wire end, and then resets. The turntable 11 drives the buzzer with the welded long wire end to move to another welding mechanism. During the welding of the short wire end, the wire clamping air clamp 212, driven by the three-way drive component 211, clamps the short wire end of the buzzer and places it on the corresponding solder point. The corresponding welding device 22 welds it. While welding, the wire clamping air clamp 212 pulls outward to break off the excess wire end, and then resets.

[0047] The buzzer wire bonding machine includes a machine base 1, with a turntable 11 mounted on its top surface. Along the outer periphery of the turntable 11, the top surface of the machine base 1 is sequentially equipped with a feeding station, a first wire bonding station, a second wire bonding station, an inspection station, and a unloading station. Two wire bonding mechanisms 2 are respectively positioned at the first and second wire bonding stations. This allows for the arrangement of corresponding processing mechanisms around the turntable 11, maximizing the use of space near the turntable 11 and reducing the required floor space.

[0048] The buzzer wire bonding machine also includes a feeding mechanism 4, which is located at the feeding station. The feeding mechanism 4 includes a feeding air clamp 41, a feeding tray 42, a first bidirectional drive 43, and a second unidirectional drive 44. The first bidirectional drive 43 is located above the turntable 11, and the feeding air clamp 41 is located on the first bidirectional drive 43. The first bidirectional drive 43 can drive the feeding air clamp 41 to move horizontally and vertically. The second unidirectional drive 44 is located below the first bidirectional drive 43, and the feeding tray 42 is located on the second unidirectional drive 44. The second unidirectional drive 44 can drive the feeding tray 42 to move longitudinally. In use, the operator places the tray containing unbonded buzzers on the feeding tray 42. During the feeding process, driven by the first bidirectional drive 43 and the second unidirectional drive 44, the feeding air clamp 41 transfers the buzzers on the tray to the positioning fixture 13, thus completing the feeding operation.

[0049] The buzzer wire bonding machine also includes a wire management mechanism 5. There are two wire management mechanisms 5, both of which are set on the top surface of the support plate 12. One wire management mechanism 5 is located between the feeding mechanism 4 and its 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 drive member 52 and a wire management air clamp 51. The wire management air clamp 51 is set on the third one-way drive member 52. The third one-way drive member 52 can drive the wire management air clamp 51 to move closer to or further away from the positioning fixture 13. After the loading is completed, the turntable 11 moves the unwelded buzzer to the wire management mechanism 5. The wire management air clamp 51 clamps the long and short wire ends of the buzzer. Then, driven by the third unidirectional drive 52, it moves away from the positioning fixture 13 to straighten the long and short wire ends so that the subsequent wire clamping device 21 can clamp the wire ends. After straightening the long and short wire ends, the wire management air clamp 51 releases the long and short wire ends and resets. The turntable 11 then moves the unwelded buzzer to the next work station.

[0050] The welding device 22 includes a fourth one-way drive 221, a support plate 222, a movable rod 223, a second spring 224, a slider 225, a mounting frame 226, and a welding head 227. The slider 225 and the fourth one-way drive 221 are both mounted on the support plate 222. The fourth one-way drive 221 is connected to the slider 225 to drive the slider 225 to move vertically. The beginning end of the mounting frame 226 is slidably mounted on the slider 225, and the end end of the mounting frame 226 extends above the positioning fixture 13. The welding head 227 is located at the end of the mounting frame 226. A boss 228 is formed on the top of the slider 225. The movable rod 223 passes through the boss 228, and the lower end of the movable rod 223 is connected to the mounting frame 226. The second spring 224 is sleeved on the movable rod 223. One end of the second spring 224 abuts against the mounting frame 226, and the other end of the second spring 224 abuts against the boss 228. After the wire end is placed on the corresponding solder point, the welding head 227 moves under the drive of the fourth unidirectional drive component 221 to weld the wire end to the corresponding solder point. After welding, the welding head 227 resets, and the turntable 11 drives the welded buzzer to the next work station. It should also be noted that during welding, the setting of the movable rod 223 and the second spring 224 can prevent the welding head 227 from making hard contact with the buzzer, which would damage the buzzer. It can also ensure that the welding head 227 always keeps in contact with the solder point of the buzzer, thus ensuring the welding effect.

[0051] The wire bonding mechanism 2 also 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 drive member 231 and a cleaning box 232. The cleaning box 232 contains solder paste and is mounted on the second bidirectional drive member 231. The second bidirectional drive member 231 can drive the cleaning box 232 to move closer to or further away from the soldering head 227. In use, the cleaning box 232 can be moved to the soldering head 227 under the drive of the second bidirectional drive member 231 so that the solder paste in the cleaning box 232 is applied to the soldering head 227 to remove impurities from the surface of the soldering head 227.

[0052] The buzzer wire bonding machine also includes a detection mechanism 6, which is located at the detection station. The detection mechanism 6 includes a fifth unidirectional drive component 61, a detection block 62, and detection pins 63. The detection block 62 is mounted on the fifth unidirectional drive component 61, which drives the detection block 62 to move vertically. There are two detection pins 63, both mounted on the detection block 62. After bonding, the turntable 11 moves the bonded buzzer to the detection mechanism 6. The detection block 62 moves under the drive of the fifth unidirectional drive component 61, causing the two detection pins 63 to contact the two solder joints, thus detecting whether the solder joints are conductive.

[0053] The buzzer wire bonding machine also includes a feeding mechanism 7, which is set at the feeding station. The feeding mechanism 7 includes a feeding air clamp 71, a feeding tray 72, a feeding rod 73, a waste bin 74, a third bidirectional drive component 75, a sixth unidirectional drive component 77, and a seventh unidirectional drive component 76. The feeding rod 73 is located below the turntable 11. Both the turntable 11 and the positioning fixture 13 have through holes for the feeding rod 73 to extend into. The sixth unidirectional drive component 77 is connected to the feeding rod 73. Next, the ejector rod 73 is driven to move vertically. The discharge air clamp 71 is mounted on the third bidirectional drive member 75, which can drive the discharge air clamp 71 to move longitudinally and vertically. The seventh unidirectional drive member 76 is mounted below the third bidirectional drive member 75. The discharge tray 72 is mounted on the seventh unidirectional drive member 76, which can drive the loading tray 42 to move laterally. The waste bin 74 is located between the turntable 11 and the discharge tray 72. In use, the operator places an empty tray on the discharge tray 72. During the discharge process, driven by the third bidirectional drive member 75, the sixth unidirectional drive member 77, and the seventh unidirectional drive member 76, the ejector rod 73 first lifts the buzzer in the positioning fixture 13, and then the discharge air clamp 71 transfers the qualified buzzer on the positioning fixture 13 to the tray. The unqualified buzzer is placed in the waste bin 74, thus completing the discharge operation.

[0054] Both the loading pallet 42 and the unloading pallet 72 have multiple placement slots on their top surfaces. A notch 45 is formed at one corner of each placement slot, and an L-shaped positioning plate 46 is installed within the notch 45. An eighth one-way drive component 47 is connected to the bottom surface of the L-shaped positioning plate 46. The eighth one-way drive component 47 can drive the L-shaped positioning plate 46 to extend into or detach from the notch 45. When placing the pallet, the eighth one-way drive component 47 drives the L-shaped positioning plate 46 to detach from the notch 45, and then the worker places the pallet into the placement slot. Finally, the eighth one-way drive component 47 drives the L-shaped positioning plate 46 to extend into the notch 45, thereby securing the pallet.

[0055] To ensure the 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 inserted into another clamping arm of the clamping air clamp 212.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
