Two first electric push rods are fixedly installed on the top of the welding table. The output shafts of the two first electric push rods are fixedly installed with the same adjustment box. A first adjustment component is arranged inside the adjustment box. Two cables are fixedly installed on the front side of the welding table. The front ends of the two cables are fixedly installed with constant temperature soldering irons. The rear sides of the two constant temperature soldering irons are fixedly installed with wire pipes.

[0033] Refer toFigure 1 , the wire bonding machine of the embodiment of the present utility model includes a wire bonding machine main body 1, a conveyor belt 2 and a feeding mechanism 3. A conveyor belt 2 is arranged between the feeding end of the wire bonding machine main body 1 and the placement platform 110. Among them, with reference to Figure 2 , the feeding mechanism 3 includes a base 100, a pushing mechanism 200, a placement rack 300, a bracket 400 and a lifting mechanism 500. A placement platform 110 is arranged on the top of the base 100, and a through hole 120 is arranged in the middle of the placement platform 110; the pushing mechanism 200 is slidably connected to the placement platform 110 so that the pushing mechanism 200 can reciprocate in a straight line direction; the placement rack 300 is fixed below the placement platform 110, and a chute is arranged through the placement rack 300 from top to bottom; the bracket 400 is provided with multiple layers of trays 410, and adjacent two layers of trays 410 are arranged at intervals to construct a placement space; the lifting mechanism 500 includes a first stepping motor 510, a screw rod 520 and a lifting rod 530. The first stepping motor 510 is fixed at the bottom of the base 100, one end of the screw rod 520 is fixedly connected to the output shaft of the first stepping motor 510, the lifting rod 530 is provided with a threaded hole, one end of the lifting rod 530 is sleeved on the screw rod 520 so that the threaded hole is in threaded cooperation with the screw rod 520, and the other end is fixedly connected to the bottom of the bracket 400; among them, the tray 410 can move into the through hole 120 so that the surface of the tray 410 is flush with the surface of the placement platform 110, and the pushing mechanism 200 can move to the surface of the tray 410 to push the materials on the surface of the tray 410.

[0034] In actual use, the wire bonding machine of the embodiment of the present utility model has the following working process:

[0035] 1. First, place the materials into the placement space between the trays 410 on the bracket 400 and support them by the trays 410;

[0036] 2. Use the lifting mechanism 500 to lift the upper bracket 400 to a position coplanar with the placement platform 110;

[0037] 3. The pushing mechanism 200 slides on the placement platform 110, and uses the pushing mechanism 200 to push the materials on the tray 410 into the conveyor belt 2;

[0038] 4. The conveyor belt 2 conveys the materials to the feeding end of the wire bonding machine main body 1 for feeding;

[0039] 5. The wire bonding machine main body 1 processes the materials and sends out the processed materials;

[0040] 6. Repeat steps 2 to 5 above;

[0041] Specifically, in step 2, the screw rod 520 driven by the first stepping motor 510 rotates. The first stepping motor 510 features high precision and can achieve precise constant-torque drive, making the stepping angle and rotation speed of the screw rod 520 constant each time it rotates. This ensures that the rising speed and rising distance of each tray 410 are consistent, guaranteeing that each tray 410 can be level with the placement platform 110, facilitating step 3. Meanwhile, in the feeding mechanism 3, the lifting mechanism 500 realizes lifting at a fixed distance and fixed speed, enabling each tray 410 to be sent above the placement platform 110, forming intermittent feeding and improving the overall working efficiency.

[0042] In the above-mentioned step 2, when lifting the bracket 400, it is necessary to ensure that the bracket 400 does not fall to ensure safety. Therefore, in some embodiments, referring to Figure 3 , a base 130 is provided at the bottom of the base 100, and the first stepping motor 510 is fixed on the base 130.

The two ends of the support rod 550 are respectively rotatably connected to the first rotating seat 140 and the second rotating seat 532. Limit plates 150 are provided on both sides of the base 130. A reset assembly 600 is provided between the first rotating seat 140 and the second rotating seat 532 and the limit plate 150 on the same side, so that the reset assembly 600 drives the first rotating seat 140 and the second rotating seat 532 to approach each other. The first rotating seat 140 and the second rotating seat 532 provide damping force, and the damping force provides a supporting force for the entire limit plate 150 through the two limit plates 150, and then cooperates with the screw rod 520 to support the entire bracket 400. Specifically, a slide rail 141 is provided on each of the two sides of the base 130, and the two slide rails 141 are collinear. The first rotating seat 140 is slidably connected to the slide rail 141. A connecting block 531 is fixedly connected to the lower end of the lifting rod 530, and a second rotating seat 532 is provided on each of the two sides of the connecting block 531.

[0044] It should be noted that a feeding opening 310 is provided on the outer side of the storage rack 300 in an open manner. This facilitates the user to directly place materials in the storage space, and the entire feeding mechanism 3 performs automatic feeding, eliminating the need for manual placement of materials into the wire bonding machine main body 1 one by one.

[0045] In some embodiments, the bracket 400 includes four vertical rods 420, which are respectively fixed at the four corners of the tray 410, so that two opposite sides of the storage space are penetrated. Among them, one side of the storage space corresponds to the above-mentioned feeding port 310, which facilitates the user to put materials in time.

[0046] Preferably, in order to improve the support of the entire lifting mechanism 500 for the bracket 400, the upper end of the lifting rod 530 is fixedly connected to the bottom surface of the bracket 400, and a plurality of inclined reinforcing rods 540 are fixedly connected between the side surface of the lifting rod 530 and the bottom surface of the bracket 400.

[0047] In some embodiments, the pushing mechanism 200 includes a second stepping motor 210, a first swing rod 220, a second swing rod 230, and a pushing plate 240. One end of the first swing rod 220 is rotatably connected to the central position of the pushing plate 240, and the other end is rotatably connected to one end of the second swing rod 230. The end of the second swing rod 230 away from the first swing rod 220 is fixedly connected to the output end of the second stepping motor 210 and is driven to swing by the second stepping motor 210. The pushing mechanism 200 formed by the link structure can restrict the stroke of the pushing plate 240, so that the pushing plate 240 can reciprocate between two fixed positions.
