Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor production, in particular to an automatic silicon material bag pouring device. Background Art

[0002] At present, polysilicon manufacturers basically use bagging to package and ship silicon materials. Monocrystalline silicon manufacturers carry out production operations after pouring out the bagged silicon materials. Manual bagging is labor-intensive and has a poor working environment. Even though the current automatic bag pouring technology is relatively mature, it is still not suitable for automatic rewinding of silicon materials. This is because the currently commonly used automatic bag pouring method mainly uses a blade to cut a hole at any position near the bottom of the bag to make the material fall from the opening of the bag. First of all, the semiconductor production process has high requirements for the purity of silicon materials, and silicon materials are mostly in block form. During the bag-slicing process, the blade will come into contact with the silicon material, or cut the block silicon material, increasing the area of ​​the silicon material contacting the air, increasing its oxidation probability, and thus affecting the quality of the silicon material; in addition, during the knife-slicing process, the blade is easily blocked by the silicon material, and multiple operations are required to open a suitable opening for pouring the material. Multiple blade contacts with the silicon material will not only directly cause pollution, but also easily produce debris at the bag cut, and the debris will fall into the silicon material and affect the quality of the silicon material; in addition, the styles of silicon material packaging bags are diverse, and silicon materials are mostly in block form. The existing automatic bag pouring method is difficult to ensure that there is no residue of silicon material at the bottom of the bag, and there is a certain risk of raw material waste.

[0029] The technical solution of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0030] In the description of the embodiments of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood by specific circumstances.

[0031] Reference Figure 1The present embodiment provides an automatic bag pouring device for silicon materials, which includes a frame 1, on which a feeding mechanism 5, a clamping mechanism 2, a cutting mechanism 3 and a turning mechanism 4 are provided. The feeding mechanism 5 is used to transport the material bag 6 to the bottom of the clamping mechanism 2; the clamping mechanism 2 is provided between the feeding mechanism 5 and the turning mechanism 4, and is used to clamp the material bag 6 on the feeding mechanism 5 and transfer it to the turning mechanism 4; the cutting mechanism 3 is used to trim the material bag 6; and the turning mechanism 4 is used to turn over the material bag 6 trimmed by the cutting mechanism 3 for pouring the material.

[0032] During the production and packaging of silicon materials, no matter what form the material bag 6 takes, the seal must be located at the edge of the material bag 6, such as the top or side end, and generally the top end is the most common. No matter where the seal end of the material bag 6 is located, during the feeding process, the direction of the material bag 6 can be appropriately adjusted so that the seal end is located vertically upward. In this way, the silicon material will be deposited below the seal end in the material bag 6 and have a certain distance from the seal end. Therefore, when the cutting mechanism 3 is used to cut off the edge strip of the seal end of the material bag 6, the cutting mechanism 3 will not touch the silicon material, avoiding the situation where a single cutting is blocked by the silicon material and cannot be cut, and avoiding the contamination of the silicon material; then the material bag 6 is turned over by the turning mechanism 4 so that the opening is downward. No matter what shape the material bag 6 takes, the silicon material can slide smoothly along the inner wall of the material bag 6 from the opening of the material bag 6, and there will be no waste of silicon material remaining in the material bag 6.

[0033] The shape, structure, etc. of the rack 1 can be configured according to actual usage requirements, and no specific limitation is made here. Only some feasible implementation schemes are given as examples. These implementation schemes are not intended to limit the protection scope of the present utility model. Any rack 1 that can achieve the above functions should be within the protection scope of the present utility model.

[0034] Reference Figure 2-3 In some feasible implementation schemes, the frame 1 includes a vertical pole 1-1, a crossbeam 1-2 and a crossbeam 2 1-3 which are interconnected in a three-dimensional frame shape. The crossbeam 1-2 is located at the top of the vertical pole 1-1 and serves as the installation site and moving track of the clamping mechanism 2. The crossbeam 2 1-3 is arranged in the middle of the vertical pole 1-1 and serves as the installation site of the loading mechanism 5 and the turning mechanism 4.

[0035] The clamping and conveying mechanism 2 comprises a conveying member 2-1 movable on the cross beam 1-2, and a clamping claw 2-2 located at the bottom end of the conveying member 2-1. The conveying member 2-1 can move back and forth between the loading mechanism 5 and the turning mechanism 4 to transport the material bag 6 clamped by the clamping claw 2-2.

[0036] Among them, the shape, structure, etc. of the conveying member 2-1 can be configured according to actual use requirements, and no specific limitation is made here. For example, it can be a slider slidably connected to the crossbeam 1-2. In order to enable it to operate automatically, a telescopic device whose telescopic direction is parallel to the sliding direction of the slider can be connected to the slider, or a motor and a transmission device driven by the motor can be set on the frame 1, so that the transmission device drives the slider to move. The transmission devices mentioned here and later are all existing technologies, such as threaded transmission devices, meshing transmission devices, etc., which will not be elaborated; of course, the conveying member 2-1 can also be a structure such as an electric wheel rollingly connected to the crossbeam 1-2.

[0037] The clamping jaw 2-2 includes a driver 2-21, a clamping arm 2-22 and a clamping arm 2-23. The clamping arm 2-22 and the clamping arm 2-23 are rotatably connected. The driver 2-21 drives the clamping arm 2-22 to rotate so that its bottom end approaches or moves away from the clamping arm 2 2-23 to achieve the clamping or loosening of the material bag 6.

[0038] The material selection of driver 2-21 and the connection method with clamp arm 2-22 can be configured according to actual use requirements, and no specific limitation is made here. For example, it can be a telescopic device arranged outside the rotating shaft 2-24 of clamp arm 1 2-22 and clamp arm 2-23, and the rotation of clamp arm 1 2-22 is achieved by pulling clamp arm 1 2-22 away from the end of the rotating shaft 2-24. It can also be a motor connected to the rotating shaft 2-24 of clamp arm 1 2-22 and clamp arm 2-23, wherein the rotating shaft 2-24 is fixedly connected to clamp arm 1 2-22, and the rotation of clamp arm 1 2-22 can be achieved by the motor driving the rotating shaft 2-24 to rotate.

[0039] In addition, in order to meet different feeding requirements, a lifting rod 2-3 and a driver 2-4 can be arranged between the clamp 2-2 and the conveying member 2-1, and the driver 2-4 can be used to drive the lifting rod 2-3 to move so as to change the distance between the clamp 2-2 and the feeding mechanism 5. When it is necessary to clamp the bag 6, the height of the lifting rod 2-3 is lowered to make the clamp 2-2 close to the bag 6 on the feeding mechanism 5 to achieve clamping, and then the lifting rod 2-3 is raised and the conveying member 2-1 is moved to transfer the bag 6.

[0040] Similar to the driver 1 2-21, the driver 2-4 can also adopt a telescopic device or a motor device, and a connection or transmission device can be adaptively set between the lifting rod 2-3 and the driver 2-4.

[0041] The cutting mechanism 3 includes a driver 3-1, a sliding member 3-2 and a cutting knife 3-3. The blade of the cutting knife 3-3 faces the inner side of the clamp 2-2 and is connected to the clamp 2-2 through the sliding member 3-2. The driver 3-1 drives the sliding member 3-2 to move in the horizontal direction. During implementation, the cutting knife 3-3 contacts the material bag 6 clamped by the clamp 2-2, and the driver 3-1 drives the sliding member 3-2 to move, so that the cutting knife 3-3 cuts at the position between the sealing edge of the material bag 6 and the silicon material, avoiding the cutting knife 3-3 touching the silicon material and causing a single cutting failure or direct contact with the silicon material to cause pollution.

[0042] During implementation, a transverse slide rail 2-25 can be set at the bottom end of the clamp arm 1 2-22 and / or the clamp arm 2 2-23, and the sliding member 3-2 can be installed on the slide rail. The driver 3-1 can use a telescopic device or a motor device, and a connection or transmission device can be adaptively set between the driver 3-1 and the sliding member 3-2.

[0043] The above-mentioned flipping mechanism 4 includes a driver 4-1, a receiving groove 4-2 and an adsorption member 4-3, the adsorption surface of the adsorption member 4-3 faces the inner side of the receiving groove 4-2, the receiving groove 4-2 is rotatably arranged on the frame 1, and the driver 4-1 drives the receiving groove 4-2 to rotate.

[0044] The receiving groove 4-2 is at least opened at the top to receive the material bag 6, and at least at the bottom is provided with an adsorbent 4-3 to adsorb and fix the material bag 6. When the driver 4-1 drives the receiving groove 4-2 to rotate, the material bag 6 in the receiving groove 4-2 rotates accordingly and the opening direction changes, and the material can be unloaded. After the unloading is completed, the driver 4-1 can be used to rotate the receiving groove 4-2 to other directions, close the adsorbent 4-3, and remove the empty material bag 6.

[0045] In some specific embodiments, the adsorption component 4-3 includes: a slot 1 4-31 provided at the bottom of the receiving groove 4-2 and a slot 2 4-32 provided on the side wall of the receiving groove 4-2. Both the slot 1 4-31 and the slot 2 4-32 can be connected to an air supply pipe 4-33 and a negative pressure pipe 4-34. The negative pressure pipe 4-34 provides adsorption power for the slot 1 4-31 and the slot 2 4-32. The air supply pipe 4-33 blows air to the material bag 6 to remove the empty material bag 6.

[0046] Reference Figure 4 The receiving groove 4-2 can also be configured to have an open side, with the open side facing the clamping mechanism 2, so that the clamping mechanism 2 can move the material bag 6 onto it, and when removing the empty material bag 6, it is only necessary to tilt the receiving groove 4-2 toward its own open side, and use the slot 2 4-32 on the side wall to blow air, which can reduce the rotation angle of the receiving groove 4-2 when removing the empty material bag 6 and the air supply when removing the empty material bag 6, thereby saving energy.

[0047] The above-mentioned feeding mechanism 5 can be configured to be fixed or movable according to actual use requirements. If it is set to be movable, a belt conveyor mechanism can be adopted, which includes a conveyor belt 5-1, a conveyor belt 5-1 wheel and a driver 5-3. The conveyor belt 5-1 wheel is rotatably set on the frame 1, and the driver 5-3 drives the conveyor belt 5-1 wheel to rotate, so as to drive the conveyor belt 5-1 placed thereon to operate.

[0048] Both the driver four 4-1 and the driver five 5-3 can adopt a motor structure to achieve rotational drive.

[0049] In order to facilitate continuous and automatic feeding, the feeding mechanism 5 and the turning mechanism 4 are provided with a bag storage box 7, and the turning mechanism 4 is provided with a hopper 8 and a material box 9 on the side away from the feeding mechanism 5, and the material box 9 is arranged on the lower side of the hopper 8. When the device is used to automatically pour silicon bags, the steps include:

[0050] (1) Load the material bag 6 onto the loading mechanism 5 with its sealed edge facing vertically upward;

[0051] (2) Move the clamping mechanism 2 to the top of the material bag 6, lower the lifting rod 2-3, make the clamping arm 1 2-22 and the clamping arm 2-23 close to the material bag 6, rotate the clamping arm 1 2-22 in the direction close to the clamping arm 2-23, clamp the material bag 6, and transfer it to the turning mechanism 4. During the process of transferring the material bag 6, the height of the lifting rod 2-3 can be adjusted according to the different equipment heights, so that the material bag 6 is finally stably placed on the turning mechanism 4;

[0052] (3) Use the cutting mechanism 3 to cut off the sealed edge of the material bag 6, move the clamping mechanism 2 to the top of the material bag 6 storage box, and rotate the clamping arm 1 2-22 in the opposite direction to make the sealed edge fall into the material bag 6 storage box; at the same time, evacuate the slot 1 4-31 and the slot 2 4-32 to adsorb and fix the material bag 6 in the receiving groove 4-2, and flip the receiving groove 4-2 toward the side of the hopper 8 to pour the material; after the pouring is completed, flip the receiving groove 4-2 toward the side of the material bag 6 box, stop evacuating the slot 1 4-31, and supply air to the slot 2 4-32 to blow the empty material bag 6 into the material bag 6 storage box.

[0053] Compared with the prior art, the beneficial effects of the utility model are: it realizes automatic bag pouring of silicon material, and during the automatic bag pouring process, when the cutting mechanism 3 cuts off the sealing edge of the material bag 6, the cutting mechanism 3 will not touch the silicon material, which can avoid the situation that a single cut is blocked by the silicon material and cannot be cut, and avoids the contamination of the silicon material; when pouring the bag, the original sealed end of the material bag 6 faces downward, no matter what shape the other end of the material bag 6 is, the silicon material can smoothly slide down from the opening of the material bag 6 along the inner wall of the material bag 6, and no waste of silicon material will be generated in the material bag 6.

[0054] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
