Technical Field

[0001] The utility model relates to the technical field of semiconductor part processing, in particular to an auxiliary positioning device for semiconductor part processing. Background Art

[0002] Semiconductor refers to materials whose electrical conductivity at room temperature is between that of conductors and insulators. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, a diode is a device made of semiconductors. When processing semiconductor parts, auxiliary positioning devices are used to fix the semiconductor parts to ensure their stability.

[0003] The authorization announcement number in the prior art is: CN220331120U, and the name is a semiconductor parts processing auxiliary positioning device. The device not only achieves the purpose of adjusting the height, thereby improving the application range of the positioning device, but also achieves the purpose of positioning and placing the positioning device, and also achieves the purpose of facilitating the rapid positioning of semiconductor parts.

[0004] The clamping blocks of the existing auxiliary positioning devices are mostly fixed, while the shapes and specifications of semiconductor parts are diverse. It is difficult for the fixed clamping blocks to completely fit all types and specifications of semiconductor parts, so that the auxiliary positioning device cannot ensure stable fixation of various semiconductor parts, thereby affecting their subsequent processing effects. At the same time, the existing auxiliary positioning device cannot adjust the two clamping positions. The existing auxiliary positioning device will fix the semiconductor parts through two sets of clamping blocks, and the positions of the two sets of clamping blocks cannot be adjusted, which makes the fixation of the semiconductor parts not flexible enough, and may cause the clamping blocks to block the surface of the semiconductor, resulting in the inability to process the area blocked by the semiconductor parts, or the two sets of clamping blocks cannot be moved to the appropriate positions of semiconductor parts of different sizes, resulting in unstable fixation of the semiconductor parts.

When the fastening bolts 26 are tightened and support the moving frame 21, the position of the sliding frame 22 is fixed, and when the fastening bolts 26 are loosened, the position of the sliding frame 22 can be moved.

[0028] Two threaded tubes 23 are fixedly connected to the outer surface of the mobile frame 21, and the inner walls of the two threaded tubes 23 are threadedly connected with adjusting screws 24. The two adjusting screws 24 are rotatably connected to the inner wall of the fixed frame 1. The threaded tubes 23 and the mobile frame 21 are driven up and down by the rotation of the adjusting screws 24, thereby adjusting the positioning height of the semiconductor parts to facilitate different types of processing.

[0029] The top ends of the two adjusting screws 24 penetrate the fixing frame 1 and extend to the top of the fixing frame 1. The top ends of the two adjusting screws 24 are fixedly connected with sprockets 25. The fixing frame 1 is provided with a first servo motor to provide power for the rotation of the sprockets 25. The two sprockets 25 are connected by a chain transmission. Under the transmission action of the two sprockets 25 and the chain, the two adjusting screws 24 can rotate synchronously.

[0030] See also Figure 1 and Figure 3 Two clamping mechanisms 3 are arranged inside the fixing frame 1. The clamping mechanism 3 includes a U-shaped frame 31 and two symmetrical connecting frames 32. The inner wall of the U-shaped frame 31 is rotatably connected with a bidirectional screw 33. A second servo motor is arranged on the U-shaped frame 31 to provide power for the rotation of the bidirectional screw 33.

[0031] The outer surface of the bidirectional screw 33 is threadedly connected to two symmetrical internal thread moving blocks 34. The two connecting frames 32 are respectively fixedly connected to the outer surfaces of the two internal thread moving blocks 34. When the bidirectional screw 33 rotates, it can drive the two internal thread moving blocks 34 to move away from or closer to each other.

[0032] A guide rod 35 is fixedly connected to the inner wall of the U-shaped frame 31 , and two internal thread moving blocks 34 are slidably connected to the outer surface of the guide rod 35 . The guide rod 35 guides the movement of the internal thread moving blocks 34 .

[0036] The specific implementation process of the utility model is as follows: pull the operating plate 44 outward to pull the limiting rod 45 out of the replaceable clamping block 42, and then the replaceable clamping block 42 can be moved out of the mounting frame 41, and then the replaceable clamping block 42 is replaced with the specifications and shapes of the semiconductor parts to be processed, and the replaceable clamping block 42 is moved into the mounting frame 41, and then the operating plate 44 is loosened, and the limiting rod 45 is pushed to insert into the limiting hole of the replaceable clamping block 42 under the elastic force of the stretched spring 43, and then the fastening bolt 26 is loosened, and the position of the replaceable clamping block 42 is moved under the sliding action of the sliding frame 22 and the moving frame 21, and then the fastening bolt 26 is tightened to fix the sliding frame 22;

[0037] The second servo motor on the U-shaped frame 31 is controlled to operate, driving the bidirectional screw 33 to rotate, and the two internal threaded moving blocks 34 push the two connecting frames 32 closer to each other. After the two sets of replaceable clamping blocks 42 clamp and fix the semiconductor parts, the first servo motor on the fixed frame 1 is controlled to operate. Under the transmission action of the two sprockets 25 and the chain, the two adjusting screws 24 are driven to rotate synchronously, and the threaded tube 23 and the moving frame 21 are driven to move up and down, so as to adjust the height of the semiconductor parts.
