Description

Technical Field

[0001] This utility model relates to the field of polycrystalline silicon material conveying technology, and in particular to a positioning flip plate mechanism and device for transporting silicon material. Background Technology

[0002] Currently, the produced polycrystalline silicon rods (length ~3200mm, diameter 160~180mm) need to be crushed into silicon material of the required particle size (e.g., around 8mm) before they can be sold to downstream manufacturers. The feed inlet of the existing crusher is located on a platform about 2m high. When feeding, the polycrystalline silicon rods need to be lifted to this height. The specific feeding method is as follows: the trolley containing the polycrystalline silicon rods is placed in front of the platform. First, a stacker truck is used to lift the trolley containing the rods onto a hydraulic lift, and then the hydraulic lift lifts it to the platform plane. After that, two operators climb the ladder to the platform to manually feed the rods. Alternatively, the stacker truck can be used to lift the trolley containing the rods to the platform plane, and then two operators climb the platform to manually feed the rods into the crusher.

[0003] However, if the lifting machine malfunctions during the lifting process, there is a safety hazard as it may slide down midway and injure people. The material lifting method requires hydraulic vehicles and equipment; oil leaks can contaminate the operating environment and products. When the approximately 3-ton material-containing trolley is placed flat on the platform, the platform requires high strength, and the ground foundation also needs to be robust. Manual feeding is difficult to control in terms of frequency, resulting in inconsistent amounts and uneven feeding, which affects product quality and profitability. Furthermore, having two operators standing on a platform approximately 2 meters high to feed materials increases the risk of falls and injuries.

[0004] The utility model patent with patent publication number CN220371244U discloses a feeding device for crushing polycrystalline silicon rods, including a transverse moving mechanism, a longitudinal moving mechanism, and a flipping mechanism, which are connected in sequence; a rotating mechanism is located on the ground and on the side of the transverse moving mechanism away from the crusher; wherein, the rotating mechanism has at least two material trays that can rotate in the horizontal plane for placing silicon rods; when one of the material trays rotates to above the flipping mechanism, the flipping mechanism can lift the material tray to the feed port of the crusher by being driven by the longitudinal moving mechanism and the transverse moving mechanism respectively, and dump the silicon rods by flipping the material tray.

[0005] However, this patent uses a flipping mechanism to grab the material tray and flip the silicon material on the tray into the crusher at once for crushing. Because the silicon material enters simultaneously, the crusher frame is under heavy load and experiences high wear, often leading to material jamming and potential damage. Furthermore, when the silicon rods on the flipping mechanism are subjected to the same force, the impact between the silicon rods during the flipping process creates cracks on the cross-section and surface of the silicon rods. These cracks, combined with the gravity of the flipping action, cause the silicon rods to fall to the ground, increasing the amount of material that falls to the ground. Utility Model Content

[0006] The present invention aims to provide a positioning and flipping mechanism and device for transporting silicon material. The silicon material is dropped in an orderly manner by the cooperation of the slot assembly and the telescopic baffle assembly, which prevents the silicon material from being poured into the crusher at one time, thus increasing the load on the crusher and avoiding damage to the crusher due to material jamming.

[0007] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows:

[0008] A positioning flipping mechanism for transporting silicon material includes a flipping plate. The top surface of the flipping plate is provided with multiple sets of slot assemblies for placing silicon material. Each set of slot assemblies includes multiple slot pieces arranged along the total length direction of the receiving cantilever. When the flipping mechanism flips, each set of slot assemblies is provided with a telescopic baffle assembly on the side near the crusher to prevent silicon material from falling.

[0009] The slot assembly is provided in two sets. Each set of slot assembly includes four slot components arranged along the total length direction of the receiving cantilever. The slot components are V-shaped alloy strips.

[0010] The telescopic baffle assembly includes a lifting and blocking cylinder and an alloy baffle. The top of the lifting and blocking cylinder is fixedly connected to the bottom surface of the flap, and the telescopic shaft of the lifting and blocking cylinder is fixedly connected to the alloy baffle. The alloy baffle extends through the flap to the top surface of the flap and slides with the flap.

[0011] The alloy baffle is equipped with a polyurethane dust cover, which is fitted onto the top of the alloy baffle.

[0012] Each set of slot components has multiple telescopic baffle components on the side closest to the crusher.

[0013] The flap is provided with baffles on both sides along the length of the material receiving cantilever to prevent silicon material from falling from both sides.

[0014] A positioning flipping device for transporting silicon material includes the aforementioned flipping mechanism, a receiving cantilever assembly that drives the flipping mechanism to flip, a Y-axis mechanism that drives the receiving cantilever assembly to move longitudinally, and an X-axis mechanism that drives the Y-axis mechanism to move laterally. The X-axis mechanism is horizontally arranged on one side of the crusher, the Y-axis mechanism is vertically arranged on the X-axis mechanism, and the receiving cantilever assembly is arranged on the Y-axis mechanism. The flipping mechanism is connected to the side of the receiving cantilever assembly away from the Y-axis mechanism.

[0015] The X-axis mechanism includes a horizontally arranged X-axis and a transverse base. The X-axis is fixedly arranged on one side of the crusher, and the transverse base is slidably connected to the X-axis. A transverse motor is arranged on the transverse base, and the transverse motor is drivenly connected to the transverse base.

[0016] The Y-axis mechanism includes a Y-axis and a longitudinal moving base arranged horizontally on one side of the crusher. The Y-axis is fixedly connected to the transverse moving base, and the longitudinal moving base is slidably connected to the Y-axis. A longitudinal moving motor is installed on the Y-axis, and the longitudinal moving motor is drivenly connected to the longitudinal moving base.

[0017] The material receiving cantilever assembly includes a tilting motor and a rotating shaft. The rotating shaft is rotatably connected to the longitudinal moving base, the tilting motor is fixedly connected to the longitudinal moving base, and the output shaft of the tilting motor is drively connected to the rotating shaft.

[0018] The beneficial effects of this utility model are:

[0019] 1. In this utility model, by controlling the alloy baffle, the flip plate is moved above the crusher inlet, raising all the alloy baffles to block the silicon material from falling. After the flip plate mechanism flips, the alloy baffles are controlled to fall one by one from the direction closest to the crusher to the direction furthest from the crusher, thereby realizing the silicon material being poured into the crusher in sequence, avoiding instantaneous overload of the crusher that could cause jamming and damage.

[0020] 2. In this utility model, there are two sets of card slot components. Each set of card slot components holds one silicon material. Another silicon material can also be placed in the middle of the top of the two silicon materials. The three silicon materials are arranged in a triangular shape. After the flipping mechanism flips, the silicon material at the top falls directly into the crusher. After the crushing is completed, the two silicon materials at the bottom are controlled to fall one by one.

[0021] 3. In this utility model, the baffles on both sides of the flip plate and the design of multiple sets of slots prevent the silicon material from sliding sideways during the flipping process, thereby reducing the amount of material falling to the ground.

[0022] 4. In this utility model, the flipping device realizes the horizontal and vertical movement of the flipping mechanism through the X-axis mechanism and the Y-axis mechanism, moving the flipping mechanism to the silicon material feeding station or above the crusher, avoiding manual handling. The flipping mechanism is flipped through the material receiving cantilever assembly, so that the silicon material falls into the crusher by gravity. The structure is simple, easy to use, and saves manpower. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0029] Example 1

[0030] This embodiment provides a method such as Figure 1 and Figure 2 The positioning flipping mechanism for transporting silicon material shown includes a flipping plate 5. The top surface of the flipping plate is provided with multiple sets of slot assemblies for placing silicon material. Each set of slot assemblies 6 includes multiple slot pieces 7 arranged along the length direction of the receiving cantilever assembly 2. When the flipping mechanism 1 flips, each set of slot assemblies 6 is provided with a telescopic baffle assembly 8 on the side near the crusher to prevent silicon material from falling.

[0031] In this embodiment, the workers transport the silicon rods to the slots on the flip plate 5. Each set of slot components 6 holds one silicon rod, and multiple silicon rods are placed on the flip plate 5. After the flip plate 5 reaches above the crusher inlet, all the telescopic baffle components 8 are raised to prevent the silicon material from falling. After the flip plate mechanism 1 flips, the telescopic baffle components 8 on the flip plate 5 near the crusher are shortened, and the silicon material falls from the slot components 6 into the crusher below. After crushing is completed, the next telescopic baffle component 8 is shortened, and the next silicon rod falls from the slot components 6 into the crusher below, until all the silicon material on the flip plate 5 is unloaded.

[0032] This embodiment can convey multiple silicon materials at once through the flip plate 5, which improves working efficiency. At the same time, it can also control the telescopic baffle assembly 8 to drop them one by one from the direction closer to the crusher to the direction farther from the crusher, so as to realize the silicon materials are poured into the crusher one by one in sequence, avoiding the crusher from being jammed and damaged due to instantaneous overload.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 is that, in this embodiment, the slot assembly 6 is provided in two sets, and each set of slot assembly 6 includes four slot pieces 7 arranged along the length direction of the receiving cantilever assembly 2. The slot pieces 7 are V-shaped alloy strips. The rest of the structure is the same as in Embodiment 1.

[0035] In this embodiment, there are two sets of slot components 6. Each set of slot components 6 holds one silicon material. Another silicon material can be placed in the middle of the top of the two silicon materials. The three silicon materials are arranged in a triangular shape. After the flipping mechanism 1 flips, the silicon material at the top falls directly into the crusher. After the crushing is completed, the two silicon materials at the bottom are controlled to fall one by one.

[0036] Example 3

[0037] The difference between this embodiment and Embodiment 1 is that, in this embodiment, as... Figure 3 As shown, the telescopic baffle assembly 8 includes a lifting and blocking cylinder 9 and an alloy baffle 10. The top of the lifting and blocking cylinder 9 is fixedly connected to the bottom surface of the flap 5, and the telescopic shaft of the lifting and blocking cylinder 9 is fixedly connected to the alloy baffle 10. The alloy baffle 10 extends through the flap 5 to the top surface of the flap 5, and the alloy baffle 10 slides in conjunction with the flap 5. The remaining structure is the same as in Embodiment 1.

[0038] In this embodiment, when it is necessary to prevent the silicon material from falling, the telescopic rod of the lifting blocking cylinder 9 is extended, which in turn drives the alloy baffle 10 to extend. After the flipping mechanism 1 flips, the alloy baffle 10 is positioned below the silicon material on the side closest to the crusher, preventing the silicon material from sliding out of the V-shaped alloy strip and falling. When it is necessary for the silicon material to fall, the telescopic rod of the lifting blocking cylinder 9 is retracted, which in turn drives the alloy baffle 10 to retract, allowing the silicon material to slide out of the V-shaped alloy strip and fall.

[0039] Example 4

[0040] In this embodiment, the difference from embodiments 1-3 is that the alloy baffle 10 is provided with a polyurethane dust cover 20, which is fitted onto the top of the alloy baffle 10. Each set of slot assemblies 6 has multiple telescopic baffle assemblies 8 on the side closest to the crusher. The flap 5 has baffles 11 on both sides along the length of the receiving cantilever assembly 2 to prevent silicon material from falling from both sides.

[0041] In this embodiment, the alloy baffle 10 is equipped with a polyurethane dust cover. When the telescopic rod of the lifting blocking cylinder 9 retracts, the bottom of the polyurethane dust cover fits against the flip plate 5 to prevent silicon material dust from falling into the lifting blocking cylinder 9 and affecting the service life of the cylinder. The polyurethane dust cover can be disassembled and replaced after wear.

[0042] In this embodiment, each set of slot components 6 is provided with multiple telescopic baffle components 8 on the side near the crusher, which can better block the silicon material and prevent the silicon material from tilting and falling after the flip plate 5 is flipped; the baffles 11 on both sides of the flip plate 5 and the multiple sets of slots are designed to prevent the silicon material from sliding sideways during the flipping process and reduce the amount of material falling to the ground.

The worker transports the silicon rods into the slots on the flipping plate 5. Each set of slot components 6 holds one silicon rod. Multiple silicon rods are placed on the flipping plate 5. Then, the flipping mechanism 1 is moved above the crusher through the X-axis mechanism 4 and the Y-axis mechanism 3. After the flipping plate 5 reaches above the crusher inlet, the telescopic baffle assembly 8 is fully raised to prevent the silicon material from falling. After the flipping mechanism 1 flips, the telescopic baffle assembly 8 on the flipping plate 5 near the crusher is shortened, and the silicon material falls from the slot component 6 into the crusher below.
