[0030] The specific configuration and functions of the clamping device 3 and the adjusting device 4 are described in detail below.
[0031] Reference Figure 2 , Figure 3 and Figure 4As shown, in this embodiment: the clamping device 3 includes a long rod 301, which is slidably connected to the inner surface of the moving hole of the mounting platform 2, one end of the long rod 301 is fixedly connected to a connecting rod 302, one end of the connecting rod 302 is fixedly connected to a moving platform 303, and a semicircular block 304 is fixedly connected to the side of the moving platform 303 away from the connecting rod 302, a bidirectional threaded rod 305 is rotatably connected in the semicircular block 304, the arc surface of the bidirectional threaded rod 305 is threadedly connected to two clamping plates 306, and a plurality of protrusions are fixedly connected to the surface of the clamping plate 306, one end of the long rod 301 is fixedly connected to an elliptical plate 308, and a mounting plate 309 is fixedly connected to the surface of the mounting platform 2, an insertion rod 310 is slidably inserted in the mounting plate 309, a slot is provided on the surface of the elliptical plate 308, and a stopper 311 is fixedly connected to one end of the insertion rod 310. Pull the stop block 311 to drive the insertion rod 310 to slide in the mounting plate 309 until the insertion rod 310 is disengaged from the inner surface of the slot of the elliptical plate 308, and pull the elliptical plate 308 to drive the long rod 301 to slide in the moving hole of the mounting platform 2, the long rod 301 drives the connecting rod 302 to move, and the connecting rod 302 drives the moving platform 303 to move, so that the staff can place the aluminum silicon wire and prevent the aluminum silicon wire from colliding with the bonding machine body 1 during the placement process, thereby improving the stability of the device. A limiting groove is provided on the side of the mounting platform 2 close to the semicircular block 304, and a round rod 307 is fixedly connected to the surface of the clamping plate 306, and the round rod 307 is slidably connected to the inner surface of the limiting groove of the mounting platform 2.

The arc surface of the plug rod 310 is sleeved with a spring 312, and the two ends of the spring 312 are respectively fixedly connected to the block 311 and the mounting plate 309. The elliptical plate 308 is pushed to drive the long rod 301 to slide on the inner surface of the moving hole of the mounting platform 2, and the elliptical plate 308 is squeezed with the plug rod 310. At this time, the spring 312 is in a stretched state until the plug rod 310 is aligned with the slot of the elliptical plate 308.

One end of the bidirectional threaded rod 305 is fixedly connected with a handle 313, and the size of the plug rod 310 is adapted to the size of the slot of the elliptical plate 308. The handle 313 is rotated to drive the bidirectional threaded rod 305 to rotate in the semicircular block 304 , and the bidirectional threaded rod 305 drives the clamping plate 306 to move, so that the staff can stably rotate the bidirectional threaded rod 305 to accurately control the position of the clamping plate 306 .
[0032] Reference Figure 5 and Figure 6As shown, specifically, the adjustment device 4 includes a fixed rod 41, which is fixedly connected to the inner surface of the mounting groove of the mounting platform 2, and the arc surface of the fixed rod 41 is rotatably connected to the shielding plate 42, and the surface of the mounting platform 2 is fixedly connected to the slide rail 43, and the side wall of the shielding plate 42 is fixedly connected to the adjustment rod 44, and the adjustment rod 44 is slidably connected to the inner surface of the slide rail 43, and one end of the adjustment rod 44 is fixedly connected to the setting plate 45, and the setting plate 45 is internally threaded with a driving rod 46, and the driving rod 46 is against the surface of the slide rail 43, and the arc surface of the fixed rod 41 is sleeved with two torsion springs 47, and the two ends of the torsion spring 47 are respectively fixedly connected to the shielding plate 42 and the inner surface of the mounting groove of the mounting platform 2.

[0033] Working principle: when the staff needs to clamp the position of the aluminum silicon wire, the stopper 311 is pulled to drive the plug rod 310 to slide in the mounting plate 309 until the plug rod 310 is disengaged from the inner surface of the slot of the elliptical plate 308, and the elliptical plate 308 is pulled to drive the long rod 301 on the inner surface of the moving hole of the mounting platform 2, and the long rod 301 drives the connecting rod 302 to move, and the connecting rod 302 drives the moving platform 303 to move, and the aluminum silicon wire is placed on the surface of the moving platform 303, and the handle 313 is turned to drive the bidirectional threaded rod 305 to rotate in the semicircular block 304, and the bidirectional threaded rod 305 drives the clamping plate 306 to move, and the clamping plate 306 drives the round rod 307 to move inside the limiting groove of the mounting platform 2 The surface slides, pushing the elliptical plate 308 to drive the long rod 301 to slide on the inner surface of the moving hole of the mounting table 2. The elliptical plate 308 is squeezed by the insertion rod 310. At this time, the spring 312 is in a stretched state until the insertion rod 310 is aligned with the slot of the elliptical plate 308. The elastic force of the spring 312 drives the insertion rod 310 to slide in the mounting plate 309 and automatically limits the elliptical plate 308, thereby achieving the effect of fixing the position of the aluminum silicon wire, avoiding the staff from processing the aluminum silicon wire. The continuous contact of the bonding machine body 1 during the bonding process of the aluminum silicon wire will cause continuous vibration, resulting in changes in the position of the aluminum silicon wire and a decrease in the processing accuracy, thereby improving the practicability of the device.
[0034] When the staff needs to adjust the position of the baffle plate 42, the staff pulls the setting plate 45 to drive the adjustment rod 44 to slide on the inner surface of the slide rail 43, and the adjustment plate drives the baffle to rotate on the arc surface of the fixed rod 41. When it is adjusted to the appropriate position, the rotating drive rod 46 rotates in the setting plate 45 until one end of the drive rod 46 abuts against the slide rail 43. When the baffle plate 42 needs to be reset, the rotating drive rod 46 rotates in the setting plate 45 until the drive rod 46 does not abut against the slide rail 43. The torsion of the torsion spring 47 drives the baffle plate 42 to rotate on the arc surface of the fixed rod 41 and automatically reset, thereby achieving the effect of blocking external light, so that the staff can be more precise in the bonding process of the aluminum silicon wire and improve the stability of the device.
