[0002] Semiconductors are materials with electrical conductivity between insulators and conductors. Their electrical conductivity is easily controlled and can be used as a component material for information processing. Semiconductors are very important from the perspective of science and technology or economic development. The core units of many electronic products, such as computers, mobile phones, and digital recorders, use the changes in the electrical conductivity of semiconductors to process information.

[0003] The quality of semiconductor devices needs to be tested during the production process. For this purpose, CN201220213788.0 discloses a feeding device for a semiconductor device testing machine. By adding a pressing mechanism to the feeding device of a traditional testing machine, it is avoided that the substrate hits the adjacent devices during feeding due to the warping of the substrate, causing the feeding to be not smooth and resulting in product damage and scrap. However, the patent still has the problem of being unable to automatically straighten the device. When the device is placed at an angle, the staff needs to manually straighten it, thereby increasing the burden on the staff. In order to solve the problems existing in the above patents, patent CN202321160977.0 discloses a semiconductor testing feeding device, comprising: a platform, a distribution box is installed at the bottom of the platform, and both sides of the platform are fixedly connected A guardrail is connected, a motor is installed on the inner surface of the guardrail, a transmission mechanism is fixedly connected to the output end of the motor, a pressing mechanism is installed on the surface of the platform, and the pressing mechanism is located on both sides of the transmission mechanism. A tidying mechanism is installed on the inner surface of the guardrail; the tidying mechanism in this patent includes two second electric telescopic rods and a push plate, the push plate is installed on the pushing end of the electric telescopic rod, and the device is pushed to the right by the second electric telescopic rod, but since the two second electric telescopic rods may produce errors during operation, there is a possibility that the two push plates move out of sync, which causes the semiconductor device to deviate from the center. At the same time, it is difficult to control the force of the push plate to push the semiconductor device. The two push plates may cause damage to the semiconductor device in the process of tidying the semiconductor device.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1-3As shown, the utility model provides a semiconductor detection feeding device, including a conveyor belt 1, a detection mechanism is arranged at one end of the top of the conveyor belt 1, a material guide assembly is arranged at the other end of the top of the conveyor belt 1, a material assembly is arranged between the material guide assembly and the detection mechanism at the top of the conveyor belt 1, and the material assembly includes two support frames 2 symmetrically arranged on the top of the conveyor belt 1, a pair of first slide bars 3 are symmetrically arranged on the top of the opposite sides of the two support frames 2, the opposite ends of the two pairs of first slide bars 3 are commonly connected with a mounting seat 4, a turntable 5 is installed on the top of the mounting seat 4, a slider 6 is arranged between the mounting seat 4 and the two support frames 2, the two sliders 6 are respectively penetrated by the two pairs of first slide bars 3, and the sliders 6 are slidably connected to the first slide bars 3, and the bottom of the slider 6 is fixedly connected with an movable The movable frame 7 is provided with a group of second slide bars 8 penetrating through the movable frame 7, and the second slide bars 8 are slidably connected to the movable frame 7, and one end of each group of second slide bars 8 close to the mounting seat 4 is commonly connected to a push plate 9, and the other end of each group of second slide bars 8 is commonly connected to a limiting plate 10, and a gear 11 is rotatably installed at the bottom of the mounting seat 4, and racks 12 are fixedly arranged on the tops of the two push plates 9, and the two racks 12 are respectively located on both sides of the gear 11, and the two racks 12 are meshed and connected with the gear 11. When one of the racks 12 moves, it will drive the gear 11 to rotate, and the rotation of the gear 11 causes the other rack 12 to move synchronously with the rack 12 in the opposite direction, and the movement of the two push plates 9 is kept synchronized by the arrangement of the gear 11 and the rack 12.

[0023] Among them, two first connecting columns are symmetrically arranged on the top of the turntable 5, and a second connecting column is arranged on the top of the slider 6. A pull rod 13 is rotatably installed on the surface of the second connecting column, and the other ends of the two pull rods 13 are rotatably connected to the two first connecting columns respectively. During the rotation of the turntable 5, the pull rod 13 can be used to pull the two sliders 6 closer to each other or push the two sliders 6 away from each other.

[0024] The rotating disk 5 and the gear 11 are concentrically arranged.

[0025] The two sliding blocks 6 and the two pushing plates 9 are symmetrically arranged between the two supporting frames 2 .

[0026] Among them, a limiting groove 14 is provided on the side of the movable frame 7 close to the push plate 9, and a pressure sensor is installed on the inner side of the limiting groove 14. A spring 15 is also installed on the inner side of the limiting groove 14. The limiting groove 14 can limit the spring 15, and the two ends of the spring 15 are respectively against the opposite sides of the pressure sensor and the limiting groove 14. After the distance between the movable frame 7 and the push plate 9 changes, the deformation of the spring 15 will also change, thereby causing the elastic force of the spring 15 to change.

[0027] Among them, the material guide assembly includes two material guide plates 16 symmetrically arranged on the top of the conveyor belt 1, and the spacing between the two material guide plates 16 away from one end of the whole material assembly is greater than the spacing between one end close to the whole material assembly, and the distance between the two material guide plates 16 close to one end is less than the maximum spacing between the two push plates 9, and the semiconductor devices are guided between the two push plates 9 through the material guide plates 16.

[0029] Specific working principle:

[0030] Before using the utility model, first connect the external power supply and control panel of the utility model, and control the operation of the utility model through the external control panel. In the process of detecting semiconductor devices, the utility model sends the semiconductor devices into the detection mechanism through the conveyor belt 1 for detection, so as to remove defective products therein. In this process, when the semiconductor device passes between the two material guide plates 16 in the material guide assembly, it can be pushed between the two push plates 9. When the semiconductor component reaches between the two push plates 9 in the whole material assembly, the external control panel starts the motor 17 in the utility model, and the motor 17 drives the turntable 5 to rotate. During the rotation of the turntable 5, the two sliders 6 are pulled closer to each other through the two pull rods 13, and the two movable frames 7 are driven closer to each other through the sliders 6. As the two movable frames 7 approach, the two push plates 9 will be driven to approach each other at the same time. The gear 11 and rack 12 structures are provided so that the two push plates 9 can keep moving synchronously, so that the semiconductor device can be pushed to the center of the conveyor belt 1 through the two push plates 9. When the two push plates 9 contact the semiconductor device at the same time, the two push plates 9 will not continue to approach due to the obstruction of the semiconductor device, but the two movable frames 7 will continue to approach. As the movable frame 7 approaches the push plates 9, the spring 15 located between the push plates 9 and the movable frame 7 will be deformed, and the deformation will cause the pressure on the pressure sensor against the end of the spring 15 to increase. When the pressure exceeds the set value, the control motor 17 is reversed, so that the two movable frames 7 drive the push plates 9 away from the semiconductor device, thereby reducing the probability of semiconductor device damage due to excessive pressure.
