The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 3, a wire bonding apparatus 100 according to an embodiment of the invention includes a frame 110, a fixing device 150, a wire guiding device 160, and a rotating device 170. The fixing means 150, the wire guide 160 and the rotating means 170 are all provided on the housing 110.
The fixing device 150 is used to fix the bobbin 200 to be wound. The thread guiding means 160 comprises a thread guiding frame 161 for guiding thread ends of the thread to the bobbin 200 to be wound, which is fixed on the fixing means 150. The rotating device 170 is connected to the fixing device 150 for driving the fixing device 150 to rotate, thereby driving the bobbin 200 to be wound to rotate. The bobbin to be wound 200 rotated at a high speed causes the yarn to be wound around the bobbin to be wound 200, resulting in a bobbin.
The above-mentioned wire bonding apparatus 100 includes a fixing device 150, a wire guiding device 160 and a rotating device 170 disposed on the stand 110, during wire bonding, the fixing device 150 is controlled to fix the bobbin 200 to be wound, the yarn is guided to the bobbin 200 to be wound near the fixing device 150 by the wire guiding device 161, the rotating device 170 is controlled to drive the fixing device 150 to rotate, thereby driving the bobbin 200 to be wound to rotate, and the yarn is wound on the bobbin 200 to be wound, thereby realizing the automation of the initial winding of the yarn on the bobbin 200 to be wound, reducing the labor cost and improving the production efficiency.
After the winding of one bobbin is completed, the yarn between the bobbin and the lead frame 161 is cut, and the bobbin is wound up, so that the next wire bonding work of the bobbin 200 to be wound can be performed.
In one example, the number of turns of the rotation device 170 that drive the rotation of the fixture 150 may be parameterized as desired to enable the length of the wound yarn on the bobbin to be determined.
In one example, the lead assembly 160 further includes a human-machine interface 120 for performing device control operations such as switching, parameter setting, and the like.
In one example, the lead frame 161 includes a mounting bar and a guide disposed on the mounting bar. The yarn may be wound on the guide, and after cutting the yarn, the thread end of the yarn can be maintained on the lead frame 161, facilitating the next thread-bonding work of the bobbin 200 to be wound.
In one example, the lead arrangement 160 further includes a displacement drive component. The displacement driving part is connected to the lead frame 161 for driving the lead frame 161 toward or away from the bobbin 200 to be wound fixed on the fixture 150. In this example, after the fixture 150 fixes the bobbin 200 to be wound during the wire bonding work, the displacement driving part drives the lead frame 161 to approach the bobbin 200 to be wound fixed on the fixture 150 so that the wire end approaches the bobbin 200 to be wound. When the wire bonding work of one bobbin is completed, the displacement driving part drives the lead frame 161 away, leaving an operation space for transferring and fixing the next bobbin 200 to be wound.
In one example, the lead assembly 160 further includes a wobble drive member. The swing driving part is connected to the lead frame 161 for driving the lead frame 161 to swing reciprocally along the bobbin 200 to be wound in rotation. In this example, during the wire bonding process, the swing driving part drives the lead frame 161 to swing reciprocally along the rotating bobbin 200 to be wound, so that the yarn can be wound on the bobbin 200 relatively uniformly.
In one example, the fixture 150 includes a first clamping member 151, a second clamping member 152, and a clamping drive member 153. The clamping driving member 153 is connected to the first clamping member 151 and/or the second clamping member 152, and the clamping driving member 153 is used for driving the first clamping member 151 and the second clamping member 152 to approach each other or to separate from each other. It will be appreciated that the first clamping member 151 and the second clamping member 152 are capable of cooperatively clamping the bobbin 200 to be wound when they are brought into proximity with each other. After the wire bonding is completed, the first and second clamping members 151 and 152 are moved away from each other, and the bobbin can be released.
In one example, the first clamping member 151 is located directly above the second clamping member 152, and the clamping driving member 153 is used to drive the first clamping member 151 and the second clamping member 152 to move relative to each other in the vertical direction.
Further, in one example, the bobbin 200 to be wound can be placed on the second clamping member 152, and the clamping driving member 153 is connected to the second clamping member 152 for driving the second clamping member 152 to rise close to the first clamping member 151, thereby clamping the bobbin 200 to be wound.
In one example, the wire bonding apparatus 100 further includes a receiving container (not shown) disposed below the fixture 150. After the wire bonding is completed, the fixing device 150 releases the bobbin, and the bobbin can drop into the lower receiving container, so that automatic receiving is realized.
In one example, the wire bonding apparatus 100 further includes a bobbin detecting device (not shown in the drawings) for detecting whether the bobbin 200 is to be wound between the first clamping member 151 and the second clamping member 152, and a control device (not shown in the drawings) electrically connected to the bobbin detecting device, the clamping driving member 153, and the rotating device 170, and when the bobbin detecting device detects that the bobbin 200 is to be wound on the fixing device 150, the control device controls the clamping driving member 153 to drive the first clamping member 151 and the second clamping member 152 to clamp the bobbin 200, and controls the rotating device 170 to drive the fixing device 150 to rotate. The bobbin detection device may be, but is not limited to, a photodetector.
