Description

Technical Field

[0001] This invention relates to the field of monocrystalline silicon manufacturing technology, and specifically to a device for re-feeding bucket angle flipping. Background Technology

[0002] In the production process of monocrystalline silicon, multiple refills of silicon material with specific proportions are required in the crystal growth furnace. The required silicon material is collected in a refilling container and then transported to the crystal growth furnace for replenishment. The refilling container is typically mounted on a transport vehicle for transport, and is tilted during transport. This tilted loading position can lead to silicon residue. CN218621125U discloses an automatic feeding system for a monocrystalline furnace, including a material holding device, a conveying device, a feeder, and a feeder transport vehicle. The feeder is located on the feeder transport vehicle. On the vehicle, a material holding device is located above one end of the conveyor, and a feeder is located below the other end. The material holding device is equipped with a weighing device to measure the weight of the raw materials in real time. A conveying device, including a vibrator, is also located at the outlet of the material holding device. The conveyor also includes a guide plate, a protective cover, and a feeding funnel. The guide plate is inclined at the outlet of the conveyor, and a feeding funnel is located below the guide plate via a funnel support. The feeding funnel is lifted or rotated below the guide plate by a funnel cylinder. The conveyor and guide plate are covered with a protective cover. The re-feeding bin is tilted by the transport vehicle, but this structure makes it difficult to ensure precise alignment between the inlet and outlet of the re-feeding bin, and the alignment effect is difficult to adjust, thus having shortcomings. Summary of the Invention

[0003] To avoid the shortcomings of existing technologies, this invention provides a high-precision automated re-feeding bucket angle flipping device.

[0004] The present invention solves the technical problem by adopting the following technical solution: a device for flipping the angle of a refilling bucket, used to flip the refilling bucket from an inclined state to a vertical state, comprising:

[0005] The support section has a passage in the middle for a transport vehicle to enter, and the transport vehicle is used to set up the refilling bin;

[0006] A flipping part is provided at the upper end of the support part. The flipping part includes a base, a flipping plate and a flipping drive body. One end of the flipping plate is rotatably connected to the base. The flipping drive body is provided on the base and connected to the flipping plate. The flipping drive body is used to drive the flipping plate to rotate.

[0007] Two lifting and translating sections are arranged on both sides of the support section channel, the lifting and translating sections comprising:

[0008] The longitudinal translation module is mounted on the support plate; and

[0009] The connecting seat is linked to the longitudinal translation module; and

[0010] The lateral translation module is mounted on the connector; and

[0011] A bracket is installed on the transverse translation module, and the bracket reciprocates in the vertical and horizontal directions with the lifting and translation part and the transverse translation module;

[0012] The bracket is used to support the transport vehicle, the tilting plate is used to support the refilling bucket, and the tilting plate is tilted at the same angle as the refilling bucket.

[0013] In several embodiments, the base and the support are connected by a horizontal translation module, and the base can perform horizontal linear reciprocating motion on the support along with the horizontal translation module.

[0014] In several embodiments, a positioning mechanism is provided at the lower end of the flip plate. The positioning assembly includes a V-shaped outer shell and two positioning components symmetrically arranged on the outer shell. The positioning assembly includes a base plate, an elastic guide component, a contact plate, and a micro switch. The micro switch is located between the base plate and the contact plate. The contact plate is connected to the elastic guide component and is used to contact and cooperate with the refilling bucket. The contact plate can contact the micro switch under the action of the refilling bucket. The micro switch is used to control the movement of the base with the horizontal translation module.

[0015] In several embodiments, a push cylinder is provided below the positioning mechanism. The push cylinder is connected to the flip plate and is used to push the positioning mechanism to move linearly perpendicular to the flip plate.

[0016] In several embodiments, the elastic guide assembly includes a guide post, a spring sleeved on the guide post, and a bushing sleeved on the guide post. The two ends of the bushing are respectively connected to the spring and a contact plate, and the two contact plates are arranged in a V-shape.

[0017] In several embodiments, the lateral translation module is perpendicular to the direction of movement of the horizontal translation module.

[0018] Furthermore, the refeeding system including the aforementioned refeeding bucket angle flipping device also includes a feeding section, a material lifting section, and a discharging section. The material lifting section is used to lift the silicon material from the feeding section to the discharging section, and the discharging section is used to transport the silicon material into the refeeding bucket in a vertical state.

[0019] In several embodiments, the unloading section includes a feeding hopper, a first cover, an intermediate hopper, a second cover, and a discharge funnel arranged sequentially. The feeding hopper is mounted on a support, the intermediate hopper is connected to a base, the first cover and the second cover are retractable, and a first support seat is provided below the discharge funnel, which is connected to a flip plate.

[0024] S30: The horizontal translation module, together with the bracket, drives the transport vehicle to move backward until the re-feeding bucket comes into contact with the positioning mechanism. The micro switch in the positioning mechanism controls the opening and closing of the horizontal translation module, which in turn drives the tilting plate to move left and right until the re-feeding bucket is in the center position. At this time, the transport vehicle drives the re-feeding bucket to keep tilted and move upward until the discharge funnel and dust removal pipe both enter the re-feeding bucket.

[0025] S40: The longitudinal translation module drives the transport vehicle to descend, while the lateral translation module drives the transport vehicle to move backward. At the same time, the tilting drive unit drives the tilting plate to gradually rotate from the tilted state to the vertical state, realizing the transformation of the re-feeding bucket from the tilted state to the vertical state, and feeding material into the re-feeding bucket.

[0026] The beneficial effects of this invention are as follows:

[0040] like Figures 1-7 As shown, specifically, the support part 10 is a bracket structure with a passage 11 in the middle for the transport vehicle to enter. Ladders or other structures can be installed on both sides of the passage 11 to facilitate climbing and maintenance. The transport vehicle is used to set up the refilling bin. The transport vehicle is a conventional accessory in the field and can be used with AGV trolleys to achieve automatic movement. The refilling bin is used to hold silicon material and is a conventional accessory in the field. No further description or limitation will be made here.

[0041] The flipping part 20 includes a base 21, a flipping plate 22, and a flipping drive body 23. One end of the flipping plate 22 is rotatably connected to the base 21. The flipping drive body 23 is disposed on the base 21 and connected to the flipping plate 22. The flipping drive body 23 is used to drive the flipping plate 22 to rotate. The flipping plate 22 is used to support the refilling bucket. The inclination of the flipping plate 22 is consistent with the inclination of the refilling bucket.

[0042] The base 21 and the support 10 are connected via a horizontal translation module. The base 21 can perform horizontal linear reciprocating motion on the support 10 with the horizontal translation module. The horizontal translation module can use conventional components in the field, such as a lead screw drive mechanism, a linear module, etc., which can realize the left-right translation of the entire flipping part 20. Figure 5 As shown, the position of the horizontal translation module is obscured by the accordion covers 200 on both sides, so it is not shown.

[0043] Additionally, a positioning mechanism 40 is provided at the lower end of the flip plate 22. The positioning assembly includes a V-shaped outer shell 41 and two positioning components symmetrically arranged on the outer shell 41. The positioning assembly includes a base plate 42, an elastic guide component 43, a contact plate 44, and a micro switch 45. The micro switch 45 is located between the base plate 42 and the contact plate 44. The contact plate 44 is connected to the elastic guide component 43 and is used to contact and cooperate with the refilling bucket. The contact plate 44 can contact the micro switch 45 under the action of the refilling bucket. The micro switch 45 is used to control the movement of the base 21 with the horizontal translation module.

[0044] Additionally, a push cylinder 46 is provided below the positioning mechanism 40. The push cylinder 46 is connected to the flip plate 22 and is used to push the positioning mechanism 40 to move linearly in a direction perpendicular to the flip plate 22. The elastic guide assembly 43 includes a guide post, a spring sleeved on the guide post, and a bushing sleeved on the guide post. The two ends of the bushing are respectively connected to the spring and the contact plate 44. The two contact plates 44 are arranged in a V-shape.

[0045] Furthermore, the unloading section 70 includes a feeding hopper 71, a first cover 72, an intermediate hopper 73, a second cover 74, and a discharge funnel 75 arranged sequentially. The feeding hopper 71 is mounted on the support section 10, and the intermediate hopper 73 is connected to the base 21. Both the first cover 72 and the second cover 74 are retractable and adopt an accordion cover structure. A first support seat 76 is provided below the discharge funnel 75, and the first support seat 76 is connected to the flip plate 22.

[0046] The dust removal assembly includes a dust removal pipe 81, a guide pipe 82, a second support base 83, a pulley 84, and a pulley lifting mechanism 85. The second support base 83 is mounted on the flip plate 22 and supports the guide pipe 82. One pulley 84 is mounted on the base 21, and the other pulley 84 is mounted on the pulley lifting mechanism 85. The pulley lifting mechanism 85 drives the pulley 84 to move up and down. The dust removal pipe 81 passes through the two pulleys 84 and enters the guide pipe 82.

[0047] like Figure 8 As shown, the lifting and translating unit 30 includes: a longitudinal translating module 31 mounted on a support plate; a connecting seat 32 linked to the longitudinal translating module 31; a lateral translating module 33 mounted on the connecting seat 32; and a bracket 34 mounted on the lateral translating module 33. The bracket 34 reciprocates vertically and horizontally with the lifting and translating unit 30 and the lateral translating module 33. The bracket 34 is used to support the transport vehicle. The longitudinal translating module 31 and the lateral translating module 33 can adopt conventional components in the field, such as screw drive mechanisms or linear modules. Their movement directions are perpendicular, that is, the longitudinal translating module 31 moves up and down, and the lateral translating module 33 moves back and forth. The lateral translating module 33 moves left and right, which is perpendicular to the movement direction of the lateral translating module.

[0048] Furthermore, the feeding method of the aforementioned refeeding system includes the following steps:

[0049] S10: The transport vehicle carries the refill bucket into the designated position in the channel 11 of the support section 10, at which time the refill bucket is in an inclined state;

[0050] S20: The longitudinal translation module 31 drives the bracket 34 to support both sides of the transport vehicle and lift it up until the re-discharge bucket is lifted to the height of the positioning mechanism 40 on the tipping plate 22.

[0051] S30: The horizontal translation module 33, together with the bracket 34, drives the transport vehicle to move backward until the re-feeding barrel comes into contact with the positioning mechanism 40. The micro switch 45 in the positioning mechanism 40 controls the opening and closing of the horizontal translation module, which in turn drives the tilting plate 22 to move left and right until the re-feeding barrel is in the center position. At this time, the transport vehicle drives the re-feeding barrel to keep tilted and move upward until the discharge funnel 75 and the dust removal pipe 81 both enter the re-feeding barrel.

[0052] S40: The longitudinal translation module 31 drives the transport vehicle to descend, while the lateral translation module 33 drives the transport vehicle to move backward. At the same time, the flipping drive 23 drives the flipping plate 22 to gradually rotate from the tilted state to the vertical state, realizing the transformation of the refilling bucket from the tilted state to the vertical state, so that materials can be added into the refilling bucket.

[0053] In summary, the present invention employs the linkage between the flipping part and the lifting and translating part to achieve stable flipping action of the long-length, high-quality re-feeding barrel, and can also achieve alignment between the re-feeding barrel and the discharge funnel, ensuring that silicon material and dust removal pipe can accurately enter the re-feeding barrel, ensuring the docking feeding effect and improving the dust removal effect.
