It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0028] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0029] The following describes a bonding wire annealing device with cleaning and anti-pollution functions provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0030] Example 1:

[0031] Combine Figure 1-4 As shown, the present invention provides a bonding wire annealing device with cleaning and anti-pollution functions, comprising an annealing mechanism 100 and a cleaning mechanism 200. The annealing mechanism 100 comprises an annealing machine 110, a guide frame 120 provided at the front side of the annealing machine 110, and a plurality of guide rollers 130 movably installed inside the guide frame 120.

[0032] The cleaning mechanism 200 includes a water pump 210 provided on one side of the guide frame 120, a shower head 220 connected to the water outlet of the water pump 210, a cleaning chamber 230 sleeved on the outer end of the shower head 220, a scrubbing brush 240 connected to the bottom of the inner cavity of the cleaning chamber 230, a plurality of guide blocks 250 connected to the top of the scrubbing brush 240, a guide groove 260 opened inside the guide block 250, and a fan 270 installed on one side of the cleaning chamber 230. Rectangular openings are opened on both sides of the cleaning chamber 230.

[0033] Furthermore, multiple guide rollers 130 are arranged in groups of two, and are set as two groups. The two groups of guide rollers 130 are respectively located at both ends of the guide frame 120, and the two guide rollers 130 in each group are placed vertically together. With this layout design, the direction of the bonding wire can be well guided, so that the bonding wire can accurately enter the interior of the cleaning chamber 230.

[0034] Furthermore, the two rectangular openings are located on the same horizontal plane, and the fan 270 is located at the top of the rectangular openings. This layout design ensures that the bonding wires can smoothly enter and exit the cleaning chamber 230.

[0035] Example 2:

[0036] Combine Figure 1 As shown, based on the first embodiment, a water receiving box 300 is movably connected to one side of the guide frame 120, and the bottom of the water pump 210 and the bottom of the cleaning chamber 230 are fixedly connected to the bottom of the inner cavity of the water receiving box 300. The setting of the water receiving box 300 provides conditions for uniformly collecting used liquid water to avoid wasting water resources.

[0037] Furthermore, a plurality of drainage holes 400 are provided at the bottom of the cleaning chamber 230, and the plurality of drainage holes 400 are arranged at equal intervals in a matrix. The cleaning chamber 230 is connected to the interior of the water receiving box 300 through the plurality of drainage holes 400. The provision of the drainage holes 400 can prevent the water in the cleaning chamber 230 from being unable to be discharged.

[0038] Example 3:

[0039] Combine Figure 1 As shown, in the above embodiment, an ash receiving rack 500 is installed on the front side of the annealing machine 110. The ash receiving rack 500 is located between the two sets of guide rollers 130. The ash receiving rack 500 can prevent the residue on the bonding wire from falling to the ground and maintain the working environment.

[0040] Furthermore, two support rods are installed at the bottom of the ash receiving frame 500 , and the bottom ends of the support rods are fixedly connected to the outer wall of the guide frame 120 . The provision of the support rods can improve the connection firmness between the ash receiving frame 500 and the annealing machine 110 .

[0041] The working principle and usage process of the present invention are as follows: before using the device, the staff will pass the bonding wire through two sets of guide rollers 130, and then through a plurality of guide grooves 260, and then connect it to the external winder. Then when the device is used, the bonding wire will be heated to red temperature by the annealing machine 110 when passing through the annealing machine 110, and then enter the cleaning chamber 230. Here, the water pump 210 draws water and then sprays it with a shower head 220 to cool the bonding wire. Then, the bonding wire is guided by multiple guide grooves 260 and contacts the soft hair on the brush 240. The soft hair scrapes off the residue on the bonding wire, thereby improving the forming effect of the bonding wire. Then, when passing through the cleaning chamber 230, it is blown dry by the fan 270. The cleaning operation is delicate and the cleaning effect is improved.

[0042] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
