Abstract
Description
Technical Field
[0001] The utility model relates to the field of semiconductors, in particular to a material hooking mechanism. Background Art
[0002] Semiconductors refer to materials with electrical conductivity between conductors and insulators at room temperature. Semiconductors are widely used in radios, televisions and temperature measurement. For example, diodes are devices made of semiconductors. Semiconductors refer to materials with controllable electrical conductivity, ranging from insulators to conductors. Whether from the perspective of science and technology or economic development, the importance of semiconductors is very huge. Most of today's electronic products, such as computers, mobile phones or core units of digital recorders, are closely related to semiconductors. Common semiconductor materials include silicon, germanium, arsenide, etc., and silicon is the most influential semiconductor material in commercial applications. At present, semiconductor IC cutting and forming equipment is usually needed to cut and form semiconductors before packaging semiconductor objects, so that semiconductor objects can be separated separately.
[0003] The discharge mechanism is the last process in the semiconductor IC cutting and forming equipment. The existing discharge mechanism (such as Figure 1 As shown in the figure, the mold guide rail and the discharge guide rail are generally driven by two motors respectively. One of the servo motors drives the mold track A. The positioning ejector on the guide rail passes through the product positioning hole and moves forward synchronously with the track. When it approaches the discharge mechanism, if the pressure wheel does not press the product, the other servo motor will drive the pressure wheel to make an empty stroke; if the pressure is too high, the product may be damaged. After the product is taken away or manually repositioned, the pressure wheel drives the product to the discharge mechanism to complete the discharge.
[0004] Since the two motors operate separately, the connection rate cannot be guaranteed when the product runs to the discharge mechanism. When the connection rate is low or the pressure of the pressure wheel is high, it will affect the operation of the product on the discharge mechanism and may cause the product to be scrapped.

One end of the linear motion module A3 is connected to a connecting rod 7, and the end of the connecting rod 7 is connected to a linear motion module B8, so that a linkage mechanism is formed among the driving mechanism 2, the linear motion module A3, and the linear motion module B8, so that the driving mechanism 2 synchronously drives the linear motion module A3 and the linear motion module B8 to move forward and backward, the top surface of the linear motion module B8 is provided with a mold track B9, and the top of the mold track B9 is provided with a material hooking positioning ejector B10.
[0021] The linear motion module A3 and the linear motion module B8 are connected by using a connecting rod 7. When the linear motion module A3 is driven to move forward and backward by the set driving mechanism, the linear motion module B8 is driven to move forward and backward by the connecting rod 7, so that the two mold tracks can run synchronously. The pressure wheel of the prior art is replaced by a hook positioning ejector B10, which can be efficiently positioned with the positioning hole on the product. Since the two tracks run synchronously, the connection rate is guaranteed so that the mold track can smoothly deliver the product without damaging the product. Only one driving mechanism is used, saving the overall machine and usage costs.

The screw is rotatably installed on the two bearing seats, and the slider is threadedly sleeved on the surface of the screw. The servo motor is connected to the screw through a belt and a pulley. There are two pulleys, which are respectively fixedly installed on the output shaft of the servo motor and one end of the screw, and the belt is sleeved on the two pulleys.
[0023] When working, turn on the servo motor, and drive the screw to rotate through the belt and pulley, so that the slider on the surface of the screw can move freely back and forth, and then drive 3 to move synchronously, and drive the linear motion module B8 to move together under the action of the connecting rod 7, so as to realize the linkage between the driving mechanism 2, the linear motion module A3, and the linear motion module B8, and only use one servo motor, saving the overall machine and use cost.

[0026] As one of the embodiments, one end of the connecting rod 7 is connected to the slider B82, and the other end is connected to the slider A32.
[0027] The working principle of the utility model is as follows: the servo motor is turned on to drive the screw rod to rotate and make the slider move forward and backward. Under the action of the connecting component 5, the mold track A4 moves, and while the slider moves, the slider A32 is driven to move synchronously at the top of the guide rail A31. Under the action of the connecting rod 7, the slider B82 is driven to move at the top of the guide rail B81, so that the slider, the slider A32, and the slider B82 move synchronously, ensuring the connection rate between the mold track B9 and the hook positioning ejector A6.
