Description

Technical Field

[0001] This application belongs to the technical field of material conveying equipment, and more specifically, relates to a material preparation device and a material supply system. Background Technology

[0002] Modern industrial production demands increasingly higher levels of automation. For example, in the manufacturing sector, equipment is not only required to evolve towards numerical control with increasingly higher levels of automation, but also to achieve fully automated production lines and "lights-out" factories. In the monocrystalline silicon production process of the photovoltaic industry, polysilicon material preparation has traditionally been done manually. This process leads to severe polysilicon powder contamination, and prolonged manual operation can easily cause occupational diseases. Furthermore, frequent material preparation is not only labor-intensive but also prone to errors in material formulation and product contamination, resulting in higher defect rates. Due to the unique nature of this production process, no automated equipment is currently available, resulting in low automation levels and slow production cycles. Summary of the Invention

[0065] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of the present invention; the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0066] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. Similar reference numerals and letters denote similar items in the following figures; therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0067] Currently, in the monocrystalline silicon production process of the photovoltaic industry, such as the preparation of polysilicon, due to the special nature of this production process, there is no automated equipment available, and preparation has traditionally been done manually. However, polysilicon powder causes significant pollution, and prolonged manual operation can easily lead to occupational diseases, affecting the health of workers. Furthermore, frequent preparation operations not only consume manpower but also increase the risk of errors in the preparation formula and product contamination, leading to higher defect rates. This results in low automation and slow production cycles in the production process.

[0068] To address the issues of dust pollution, low automation, and low production efficiency in the preparation process of materials such as polysilicon, which are prone to dust contamination, this embodiment provides a material preparation device and a feeding system.

[0069] like Figure 1-8As shown, the material preparation device provided in this embodiment includes a dust collection box 1 and a storage tray 2. The storage tray 2 can be used for temporary storage of materials such as polysilicon that are prone to dust pollution.

[0070] The dust collection box 1 has a closed structure between its sides and top, and a discharge port 11 is provided at the bottom of the dust collection box 1. The storage tray 2 is placed inside the dust collection box 1 to provide a relatively closed material preparation environment and avoid the material in the storage tray 2 from causing dust pollution to the surrounding environment.

[0071] Furthermore, a clamping mechanism 3 and a feeding drive mechanism 4 are provided on the dust collection box 1. The clamping mechanism 3 can be used to clamp and fix the storage tray 2, and the feeding drive mechanism 4 can be used to control the storage tray 2 to flip over, so that the material in the storage tray 2 can be poured out and output from the discharge port 11 of the dust collection box 1. Throughout the entire process, manual intervention can be effectively reduced or even avoided, preventing dust pollution from affecting the health of operators. At the same time, the operation of the clamping mechanism 3 and the feeding drive mechanism 4 effectively improves the degree of automation, makes the production cycle more compact, facilitates quality control, and improves production efficiency.

[0072] As one application example, a feed inlet 12 is provided on the front side of the dust collection box 1. The feed inlet 12 can be used by external equipment to replenish the material in the storage tray 2; or, the feed inlet 12 can be used to replace different storage trays 2, and the material can be replenished by directly replacing the storage tray 2.

[0073] In some embodiments, a cover plate 13 is provided on the dust collection box 1 corresponding to the feed inlet 12. The cover plate 13 can be moved to cover the feed inlet 12, or it can be moved to expose the feed inlet 12. When the cover plate 13 is moved to cover the feed inlet 12, the cover plate 13, the other sides of the dust collection box 1, and the top of the dust collection box 1 together form a closed structure.

[0074] In some embodiments, the cover plate 13 is hinged to the dust collection box 1; for example, the upper end of the cover plate 13 is hinged and fixed, and the opening or closing of the feed inlet 12 is achieved by swinging the cover plate 13.

[0075] In some embodiments, a telescopic cylinder 131 is provided between the cover plate 13 and the dust collection box 1; for example, the fixed end of the telescopic cylinder 131 is installed on the outer side of the dust collection box 1, and then the movable end of the telescopic cylinder 131 is connected to the cover plate 13, so as to control the swing state of the cover plate 13 by controlling the telescopic movement of the telescopic cylinder 131.

[0076] As one application example, at least one dust collection port 14 is provided on the side of the dust collection box 1. The dust collection port 14 protrudes outward from the side of the dust collection box 1 and is connected to the internal space of the dust collection box 1. In use, the dust suction pipe of the dust collection system can be connected and installed at the dust collection port 14 to suck up and collect the dust generated inside the dust collection box 1, thereby reducing the dust concentration inside the dust collection box 1 and further improving the application effect of the material preparation device.

[0077] In some embodiments, such as Figure 1-3 As shown, four dust collection ports 14 are provided, arranged in pairs on both sides of the dust collection box 1. Furthermore, two dust collection ports 14 on the same side are arranged one above the other. The upper dust collection port 14 can be used to collect dust from the storage tray 2, while the lower dust collection port 14 can collect dust when material is poured from the storage tray 2, resulting in better dust collection.

[0078] As one application example, a feeding funnel 5 is provided at the feeding port 11. The feeding funnel 5 includes a first arc-shaped feeding section 51 and a second arc-shaped feeding section 52 arranged symmetrically. An obstacle avoidance zone 53 is formed between the first arc-shaped feeding section 51 and the second arc-shaped feeding section 52. The obstacle avoidance zone 53 enables the material preparation device to have a certain obstacle avoidance capability, thereby making it applicable to different receiving equipment or different feeding environments and improving its applicability.

[0079] In some embodiments, the cross-sectional shape of both the first arc-shaped feeding section 51 and the second arc-shaped feeding section 52 is C-shaped; and the top ends of the first arc-shaped feeding section 51 and the second arc-shaped feeding section 52 are connected to facilitate the entry of materials, while the bottom ends of the first arc-shaped feeding section 51 and the second arc-shaped feeding section 52 are independent of each other, realizing separate feeding. In this case, the arrangement of the first arc-shaped feeding section 51 and the second arc-shaped feeding section 52 can help to reduce the impact force of materials during feeding, and the feeding effect can be better.

[0080] As one application example, the feeding funnel 5 is rotatably disposed at the feeding port 11, and the dust collection box 1 is provided with a rotating mechanism 6; the rotation of the feeding funnel 5 can be controlled by the rotating mechanism 6, including feeding operation in the rotating state, and rotating the feeding funnel 5 to a certain angle to avoid external obstacles, thereby improving the application effect of the feeding funnel 5.

[0081] In some embodiments, the rotating mechanism 6 includes a first motor 61, a driving wheel 62, and a driven wheel 63. The first motor 61 is mounted on the dust collection box 1, and the driving wheel 62 is mounted on the power output end of the first motor 61, for example, the driving wheel 62 is directly mounted on the rotating shaft of the first motor 61. The driven wheel 63 is mounted on the feeding hopper 5, and the driving wheel 62 and the driven wheel 63 are connected in a transmission manner. In this case, the first motor 61 can drive the rotation of the driving wheel 62, which in turn drives the rotation of the driven wheel 63, thereby driving the feeding hopper 5 to rotate.

[0082] In some embodiments, the driven wheel 63 is an annular gear ring sleeved on the outer periphery of the feeding hopper 5, and the driving wheel 62 is meshed with the annular gear ring. By configuring the driving wheel 62 and the driven wheel 63 to mesh in the form of gears, the positional accuracy of the feeding hopper 5 during rotation can be improved.

[0083] In some embodiments, each of the first arc-shaped feeding section 51 and the second arc-shaped feeding section 52 is provided with a corresponding vibrator 7. The vibrator 7 can vibrate during the feeding operation of the first arc-shaped feeding section 51 and the second arc-shaped feeding section 52, thereby improving the feeding effect.

[0084] As one application example, the clamping mechanism 3 includes a first clamping arm 31, a second clamping arm 32, and a clamping drive mechanism 33. The first clamping arm 31 and the second clamping arm 32 are located on both sides of the storage tray 2. The clamping drive mechanism 33 can be used to drive the relative movement between the first clamping arm 31 and the second clamping arm 32. For example, through the operation of the clamping drive mechanism 33, the first clamping arm 31 and the second clamping arm 32 can move closer to each other or further away from each other, thereby realizing the clamping or releasing operation of the storage tray 2.

[0085] In some embodiments, the clamping drive mechanism 33 includes a bidirectional lead screw 331 and a second motor 332. The bidirectional lead screw 331 is connected to the second motor 332 for transmission, and the operation of the second motor 332 drives the bidirectional lead screw 331 to rotate. The first clamping arm 31 and the second clamping arm 32 are respectively sleeved on both ends of the bidirectional lead screw 331.

[0086] In some embodiments, the first clamping arm 31 and the bidirectional lead screw 331, and the second clamping arm 32 and the bidirectional lead screw 331 are all threaded transmission connections.

[0087] In some embodiments, the dust collection box 1 is provided with an auxiliary slide rail 15, which is arranged parallel to the bidirectional lead screw 331; the first clamping arm 31 and the second clamping arm 32 are respectively provided with auxiliary sliders 34, which are slidably connected to the auxiliary slide rail 15. The auxiliary slide rail 15 and auxiliary sliders 34, when the first clamping arm 31 and the second clamping arm 32 move relative to each other, allow for more coordinated and reliable sliding movements.

[0088] As one application example, clamping plates 35 are provided between the first clamping arm 31 and the storage tray 2, and between the second clamping arm 32 and the storage tray 2. A clamping limiting mechanism is formed between the clamping plate 35 and the storage tray 2. The clamping limiting mechanism is used to ensure the reliability of the storage tray 2 in the clamping state.

[0089] In some embodiments, the clamping and limiting mechanism includes a limiting protrusion 351 and a limiting groove 21 adapted to the limiting protrusion 351; in the clamping state, the limiting protrusion 351 is embedded in the limiting groove 21, and the outer side of the limiting protrusion 351 and the inner side of the limiting groove 21 form a mutual abutting action.

[0090] In some embodiments, the width of the limiting protrusion 351 is adapted to the width of the limiting groove 21.

[0091] In some embodiments, the limiting protrusion 351 is disposed on the clamping plate 35, and the limiting groove 21 is disposed on the storage tray 2.

[0092] In some embodiments, the limiting protrusion 351 is disposed on the storage tray 2, and the limiting groove 21 is disposed on the clamping plate 35.

[0093] The interlocking connection between the limiting protrusion 351 and the limiting groove 21 can achieve a rotational limiting effect between the interlocking contact surfaces of the limiting protrusion 351 and the limiting groove 21, thereby further improving the reliability of the storage tray 2 in the flipped state.

[0094] As one application example, a plurality of supporting protrusions 352 are provided on the inner side of the clamping plate 35. At this time, the supporting protrusions 352 on the two clamping plates 35 that are arranged opposite to each other form a supporting surface for the storage tray 2 to be placed, so as to support the storage tray 2 through the supporting protrusions 352.

[0095] As one application example, the clamping plate 35 provided on the first clamping arm 31 can rotate relative to the first clamping arm 31, and the clamping plate 35 provided on the second clamping arm 32 can rotate relative to the second clamping arm 32.

[0096] In some embodiments, the feeding drive mechanism 4 includes a third motor 41, which is connected to the clamping plate 35 in a transmission manner. In this case, the clamping plate 35 can be driven to rotate by the third motor 41, thereby driving the storage tray 2 to flip and realize the pouring of materials.

[0097] On the other hand, this embodiment also provides a feeding system, such as Figure 1 As shown, the device includes a robotic arm 8 and the aforementioned material preparation device, wherein the material preparation device is disposed at the movable end of the robotic arm 8. By configuring the robotic arm 8 and arranging the material preparation device at its movable end, the material preparation device can achieve a higher degree of automation during use, thereby improving production efficiency.

[0098] In some embodiments, the robotic arm 8 may be a four-axis, five-axis, or six-axis robotic arm.

[0099] In some embodiments, the material preparation device is further provided with an industrial camera 16, such as a CCD vision recognition camera; the industrial camera 16 is located on the outside of the dust collection box 1, and the industrial camera 16 is electrically connected to the robotic arm 8.

[0100] In this embodiment, the industrial camera 16 can identify and locate the working position of the material preparation device and feed the relevant information back to the control system. The control system then sends a command to the robotic arm 8 to perform the corresponding action, thereby further improving the automation performance of the material supply system.
