Description

Technical Field

[0001] This utility model relates to the field of semiconductor device processing feeding technology, and in particular to a feeding mechanism. Background Technology

[0002] Semiconductor devices are electronic devices whose conductivity lies between that of a good conductor and an insulator. They utilize the special electrical properties of semiconductor materials to perform specific functions. When processing semiconductor devices, the semiconductor material must first be transported to the processing equipment before the processing work is carried out.

[0003] Application No.: CN202110510060.8 discloses an automatic feeding system for an automatic feeding machine used in semiconductor device processing. The system includes a feeding hopper with protruding plates on both sides above the hopper. A feeding assembly is positioned between the upper surfaces of the two protruding plates. An anti-blocking assembly is located at the center of one side of the feeding hopper. The device uses two transmission discs with main bevel gears fixedly connected at the center of their upper surfaces. Corresponding driven bevel gears are fixedly connected to opposite ends of the two discs, meshing with the main bevel gears. When feeding semiconductor devices, the system can quantitatively feed the devices, ensuring a consistent amount of semiconductor device entering the hopper each time. The entire process requires no manual supervision, exhibiting high automation and facilitating subsequent processing of the semiconductor devices, thus improving work efficiency. However, the solenoid valve on the storage hopper is constantly opening and closing, which may cause material to get stuck inside the hopper. In addition, the feeding position is fixed, which reduces the practicality of the device. Moreover, the solenoid valve is controlled by weight detection of the raw material in the receiving tray. This means that when the solenoid valve is closed, the material in the distance between the receiving tray and the storage hopper cannot be calculated, which affects the accuracy of feeding.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-3 As shown, this embodiment of the utility model proposes a feeding mechanism, including:

[0023] Support frame 1, with two movable slots 2, and a connecting frame 4 slidably connected within the two movable slots 2. An adjustment component is installed on the support frame 1, and a detection component is installed on the connecting frame 4. A storage cylinder 6 is installed on the detection component, and a discharge pipe is connected to the storage cylinder 6. A solenoid valve is fixedly installed on the discharge pipe. Processing component; The processing component includes a rotating rod and a connecting rod rotatably connected to the inner wall of the storage cylinder 6. Multiple stirring rods 7 are fixedly connected to the side wall of the rotating rod, and an elliptical plate 8 is fixedly connected to the side wall of the connecting rod. Two lifting slots 9 are opened on the inner wall of the storage cylinder 6. A set of springs 10 is fixedly connected to the inner wall of each of the two sets of springs 10. The springs 10 are in pairs. A screen 11 is slidably connected in the two lifting grooves 9. The two sets of springs 10 are fixedly connected to the screen 11. The elliptical plate 8 is located directly below the screen 11. A first sprocket 12 and a second sprocket are rotatably connected to the side wall of the storage cylinder 6. The first sprocket 12 and the second sprocket are driven by a chain 13. The first sprocket 12 is fixedly connected to the connecting rod, and the second sprocket is fixedly connected to the rotating rod. A second motor 15 is fixedly installed on the side wall of the storage cylinder 6. The rotating end of the second motor 15 is fixedly connected to the connecting rod.

[0024] Two baffles are fixedly connected to the screen 11. The two baffles are directly opposite the two lifting grooves 9. The baffles can block the lifting grooves 9 to prevent materials from entering the lifting grooves 9. The detection component includes two sets of pressure sensors 14 fixedly installed on the upper end face of the connecting frame 4. The pressure sensors 14 are in pairs. The pressure sensors 14 are existing technology. They are devices that can sense pressure signals and convert pressure signals into usable output electrical signals according to a certain rule. Their weighing principle is similar to that of an electronic scale or weighbridge. The pressure sensors 14 can indirectly measure weight by measuring the pressure applied to them by an object. This will not be elaborated here. Two fixed plates are fixedly connected to the side wall of the storage cylinder 6. The two sets of pressure sensors 14 are fixedly connected to the two fixed plates respectively. A fixed ring is fixedly connected to the side wall of the storage cylinder 6. Multiple support columns 17 are fixedly connected to the lower end face of the fixed ring. The multiple support columns 17 are fixedly connected to the two fixed plates respectively, which improves the stability of the storage cylinder 6.

[0025] The positioning assembly includes a first motor 5 fixedly connected to the side wall of the support frame 1. A threaded rod 3 and a guide rod are rotatably connected to two moving slots 2 respectively. The threaded rod 3 is threaded through the connecting frame 4. The rotating end of the first motor 5 is fixedly connected to the threaded rod 3. A displacement sensor 18 is fixedly installed on the lower end face of the connecting frame 4. The displacement sensor 18 is existing technology and is a sensor used to measure the displacement change of an object in a straight direction to achieve precise position control and monitoring. Further details are omitted here. A protective shell 16 is fixedly connected to the side wall of the support frame 1. The protective shell 16 matches the first motor 5. The protective shell 16 has multiple heat dissipation holes and can protect the first motor 5 from damage caused by external interference.

[0026] It is worth noting that the entire device controls the first motor 5, the second motor 15, the pressure sensor 14, the solenoid valve, and the displacement sensor 18 through the main control system. Since the first motor 5, the second motor 15, the pressure sensor 14, the solenoid valve, and the displacement sensor 18 matched by the main control system are common devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.

[0027] The detailed working process of this utility model is as follows:

[0028] First, the user installs the device at the designated feeding position, then feeds the semiconductor raw material into the storage cylinder 6. At this time, the pressure sensor 14 changes value, and the second motor 15 starts working. The rotating end of the second motor 15 drives the connecting rod to rotate. Subsequently, under the transmission of the first sprocket 12, the second sprocket, and the chain 13, the connecting rod and the rotating rod begin to rotate, and the elliptical plate 8 and the stirring rod 7 rotate. The elliptical plate 8 continuously impacts the screen 11, causing the screen 11 to vibrate up and down. This breaks up the agglomeration between particles, dispersing the raw material entering the storage cylinder 6. The stirring rod 7 stirs the semiconductor raw material in the storage cylinder 6, keeping the raw material in a flowing state. To facilitate material discharge, once the raw material in the storage cylinder 6 reaches the appropriate storage range, the feeding stops, and then the first motor 5 starts working, causing the threaded rod 3 to rotate. The connecting frame 4 moves within the moving groove 2, and in conjunction with the displacement sensor 18, the storage cylinder 6 can be moved to the designated feeding position, improving the practicality and portability of the device. When feeding is performed, the solenoid valve starts, and the pressure sensor 14 detects the entire storage cylinder 6. By detecting the change in the weight of the storage cylinder 6 during the feeding process, the amount of material fed can be determined when the weight of the storage cylinder 6 drops to a certain range, making the feeding more uniform, the feeding more accurate, and the degree of automation higher.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
