[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-7 A bonding wire reel quick-release assembly includes a support mechanism 1, a reel traction mechanism 2, and a reel power mechanism 4. The support mechanism 1 supports the reel traction mechanism 2, and the reel power mechanism 4 drives the reel traction mechanism 2, thereby rotating the reel mounted on the reel traction mechanism 2.

[0033] The reel traction mechanism 2 is also equipped with a disengaging mechanism 3, which pushes the reel traction mechanism 2 to move left and right.

[0034] The support mechanism 1 includes a left support cylinder 102 and a right support cylinder 103. A gap is left between the left support cylinder 102 and the right support cylinder 103 for installing a reel. A blind hole 105 is opened at the axis of the left support cylinder 102, and a through hole 106 is opened at the axis of the right support cylinder 103.

[0035] The reel traction mechanism 2 includes a reel drive rod 201. One end of the reel drive rod 201 passes through the through hole 106 and extends into the interior of the blind hole 105. The other end of the reel drive rod 201 extends out of the right side of the right support cylinder 103.

[0036] The outer surface of the winding reel drive rod 201 is provided with a telescopic groove 203. The telescopic groove 203 is located between the left support cylinder 102 and the right support cylinder 103. An elastic support member 202 is fixedly connected inside the telescopic groove 203. An elastic metal sheet 204 is installed between the bottom of the inner bottom of the telescopic groove 203 and the bottom of the elastic support member 202. The elastic metal sheet 204 applies an outward thrust to the elastic support member 202;

[0037] The axis of the right end of the winding reel drive rod 201 is fixedly connected with a traction rod 205. The outer surface of the traction rod 205 is provided with a resistance groove 206. The tray removal mechanism 3 cooperates with the resistance groove 206 to push the winding reel drive rod 201 to move left and right;

[0038] The axis of the traction rod 205 is provided with a polygonal sliding groove 207;

[0039] The output end of the tray removal mechanism 3 extends into the polygonal sliding groove 207 to drive the traction rod 205 so that the winding reel drive rod 201 rotates.

[0040] Through the above technical solution, the winding reel drive rod 201 is arranged to penetrate through the right support cylinder 103 and extend into the left support cylinder 102, and a telescopic elastic support member 202 is arranged on the surface of the winding reel drive rod 201. When winding, the winding reel is installed on the outer surface of the elastic support member 202 and is supported by the elastic support member 202. When taking the tray, the winding reel drive rod 201 is pulled to the right by the tray removal mechanism 3, so that the elastic support member 202 is compressed and contracted to release the restriction on the winding reel, and the left end of the winding reel drive rod 201 is disengaged from the left support cylinder 102, so that the winding reel directly drops. When unwinding, the winding reel is directly placed between the left support cylinder 102 and the right support cylinder 103 and waits for the winding reel drive rod 201 to penetrate and reset, achieving the effect of quickly replacing the winding reel.

[0041] Specifically, the support mechanism 1 includes two support frames 101. Installation grooves 104 are respectively arranged on the outer surfaces of the left support cylinder 102 and the right support cylinder 103. The support frames 101 are located inside the installation grooves 104, and the support frames 101 respectively fixedly support the left support cylinder 102 and the right support cylinder 103.

[0042] Through the above technical solution, the function of setting the support frame 101 is to fixedly support the left support cylinder 102 and the right support cylinder 103 and raise the heights of the left support cylinder 102 and the right support cylinder 103, so that after the wound winding reel drops, it will not affect the installation of a new winding reel.

[0043] Specifically, there are multiple telescopic slots 203. The multiple telescopic slots 203 are distributed in a circular pattern around the axis of the winding reel drive rod 201. The number of elastic support members 202 is equal to the number of telescopic slots 203.

[0044] Through the above technical solution, the purpose of setting multiple elastic support members 202 is to fix the axis of the winding reel at multiple points, so that the winding reel can be kept as much as possible at the central position of the winding reel drive rod 201. When the winding reel drive rod 201 rotates to drive the winding reel to wind the bonding wire, the tightness of the bonding wire will not be inconsistent due to the offset of the axis, and the bonding wire will not break due to uneven traction force caused by the offset of the axis.

[0045] At the same time, multiple elastic support members 202 are clamped on the axis of the winding reel by the elastic metal sheet 204. When the diameter of the axis of the winding reel is different, the telescopic of the elastic support members 202 can adapt to winding reels with different inner diameters, improving the applicability of the equipment.

[0046] Specifically, the height of the elastic support member 202 does not exceed the radius of the winding reel drive rod 201. The top of the right side of the elastic support member 202 is a slope, and the lowest surface of the slope is flush with the outer surface of the winding reel drive rod 201.

[0047] Through the above technical solution, the height of the elastic support member 202 is restricted, so that all the elastic support members 202 can shrink into the telescopic slots 203 after being stressed. When the winding reel drive rod 201 moves to the right under the action of a thrust, the right side of the elastic support member 202 will gradually enter the through hole 106. Thus, the elastic support member 202 is pressed and restricted by the mouth and inner wall of the through hole 106. At this time, the elastic support member 202 loses the restraint on the winding reel. And as the left end of the winding reel drive rod 201 enters the through hole 106, the winding reel will directly fall without support.

[0048] Specifically, the winding power mechanism 4 includes a support platform 401. A drive motor 402 is fixedly connected to the top of the support platform 401. The end of the output shaft of the drive motor 402 is fixedly connected to a polygonal drive rod 403. The polygonal drive rod 403 extends into the polygonal chute 207, and there is a space for the traction rod 205 to move horizontally between the left end of the polygonal drive rod 403 and the left end of the polygonal chute 207.

[0049] Through the above technical solution, the set support platform 401 is used to raise the drive motor 402 and support the drive motor 402, while the polygonal drive rod 403 is used to cooperate with the polygonal chute 207 to drive the winding reel drive rod 201, so that the winding reel drive rod 201 can drive the winding reel to rotate to wind the bonding wire.

[0050] When the drawbar 205 is subjected to a rightward thrust, the drawbar 205 will slide to the right with the polygonal drive rod 403 as the fulcrum. During the whole process, the winding disc drive rod 201 can always keep rotating without frequent shutdowns, so as to extend the service life of the support platform 401.

[0051] Specifically, the disc removal mechanism 3 includes a horizontal slideway 301. A threaded rod 302 is installed inside the horizontal slideway 301. A power assembly 303 is installed on the side of the horizontal slideway 301. The power assembly 303 is connected to the threaded rod 302 and drives the threaded rod 302 to rotate. A sliding block 304 is threadedly connected to the outer surface of the threaded rod 302. The rotation of the threaded rod 302 pulls the sliding block 304 to move left and right. The end of the sliding block 304 is sleeved with a resistance groove 206.

[0052] Through the above technical solution, the provided horizontal slideway 301 is used to support and limit the sliding block 304. When the power assembly 303 drives the threaded rod 302 to rotate, the sliding block 304 will be pulled by the threaded rod 302 to move left and right, so as to achieve the effect of pushing the winding disc drive rod 201 to move to the right or reset.

[0053] In order to improve the accuracy of the movement of the sliding block 304, the power assembly 303 is a servo motor.

[0054] Specifically, a blanking auxiliary track 5 is also installed between the left support cylinder 102 and the right support cylinder 103. The blanking auxiliary track 5 is a U-shaped groove. The cross-section of the U-shaped groove is higher at the front and lower at the back, and the width of the groove opening is greater than the distance between the left support cylinder 102 and the right support cylinder 103. The blanking auxiliary track 5 is located directly below the elastic support member 202.

[0055] Through the above technical solution, the provided blanking auxiliary track 5 plays an auxiliary role. After the bonding wire winding is completed and the winding disc drive rod 201 moves to the right to release the restriction on the winding disc, the winding disc will directly fall into the inside of the blanking auxiliary track 5, and then roll backward under the action of gravity and finally enter the collection box or the conveyor belt, without the need for manual removal of the winding disc or collection and classification of the winding disc.

[0056] When unwinding, the reel is simply placed between the left and right support cylinders 102 and the right support cylinder 103, and the reel transmission rod 201 is reset after passing through the left and right support cylinders 103, thereby achieving the effect of quickly replacing the reel.

[0057] By installing the unloading auxiliary track 5 between the left support tube 102 and the right support tube 103, when the reel is disassembled, the reel will directly fall into the inside of the unloading auxiliary track 5, and the inclination angle inside the unloading auxiliary track 5 will make the reel wrapped with the bonding gold wire roll backward to the conveyor belt for collection, thereby improving the convenience of use.

[0058] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
