Description

Technical Field

[0001] The present application belongs to the technical field of crystal rod production, and in particular, relates to a crystal rod transfer vehicle. Background Art

[0002] After the crystal rod is pulled in the single crystal furnace, it is necessary to use a transfer vehicle to transfer the crystal rod taken out of the single crystal furnace to the subsequent workstation for the next step of processing. The transfer vehicle usually first receives the crystal rod released from the auxiliary furnace chamber of the single crystal furnace. At this time, the crystal rod is in a vertical state. After the crystal rod is fixed, the vertical crystal rod is flipped to a horizontal state, and the transfer vehicle transports the crystal rod to the subsequent workstation.

[0003] At present, when a vertical crystal rod is flipped from a vertical state to a horizontal state, the traditional solution is to use the wire rope on the unwinding drum to achieve the flipping of the crystal rod. In this way, when the crystal rod switches from vertical to horizontal, the force on the wire rope increases due to the change in the center of mass position of the crystal rod. It is difficult to control the flipping speed of the crystal rod manually, which is prone to accidents. Moreover, the wire rope may break after long-term use. It can be seen that the crystal rod transfer vehicle in the prior art has the disadvantage of poor safety. Utility Model Content

[0004] The purpose of the present application is to provide a crystal rod transfer vehicle to solve the problem of poor safety of crystal rod transfer vehicles in the prior art.

[0005] To achieve this goal, this application adopts the following technical solutions:

[0006] A crystal rod transfer vehicle comprises a vehicle frame, a turning assembly, a clamping assembly and a pushing assembly, wherein:

[0007] The flip assembly includes a column and a first driving member, the column is flippably arranged on the frame, and the driving end of the first driving member is drivingly connected to the column; the first driving member is configured to drive the column to switch between a vertical state and a horizontal state relative to the frame;

[0008] The clamping assembly includes a first clamping jaw, a second clamping jaw and a second driving member, wherein the first clamping jaw and the second clamping jaw are arranged on the column, and the driving end of the second driving member is transmission-connected with the first clamping jaw and the second clamping jaw; the second driving member is configured to drive the first clamping jaw and the second clamping jaw to move away from or approach each other, so as to clamp or release the crystal rod;

[0009] The ejection assembly includes a tray and a third driving member, the tray is movably arranged on the column, and the driving end of the third driving member is drivingly connected to the tray;

[0010] During the process in which the second driving member drives the first jaw and the second jaw to clamp the crystal rod and the first driving member drives the column to flip from a vertical state to a horizontal state, the first jaw and the second jaw continue to clamp the crystal rod, and the tray and the column assist in supporting the clamped crystal rod; after the first driving member drives the column to flip from a vertical state to a horizontal state, the second driving member drives the first jaw and the second jaw to release the crystal rod, and the third driving member drives the tray to move toward the clamping assembly to push the released crystal rod off the column.

[0011] The crystal rod transfer vehicle of the present application, through the cooperation of the flipping assembly and the clamping assembly, continuously clamps the crystal rod by the first clamp and the second clamp during the process of flipping the crystal rod. Compared with the method of flipping the crystal rod by pulling the crystal rod with a wire rope in the prior art, the crystal rod transfer vehicle of the present application clamps and fixes the crystal rod on the column through the clamping assembly, thereby realizing stable and reliable flipping of the crystal rod and greatly improving the safety of crystal rod flipping and transportation.

[0014] Optionally, the clamping assembly also includes a first screw rod, a first nut and a second nut. The threads at both ends of the first screw rod are wound in opposite directions. The first nut and the second nut are respectively wound around the two ends of the first screw rod. The first clamp and the second clamp are respectively fixed on the first nut and the second nut.

[0015] The first nut and the second nut are respectively wound around the two ends of the first screw rod. When the first screw rod rotates, the first nut and the second nut move away from or approach each other on the first screw rod, that is, the first clamping jaw fixedly arranged on the first nut and the second clamping jaw fixedly arranged on the second nut move away from or approach each other. The first clamping jaw and the second clamping jaw are moved closer to or away from each other by the transmission mode of the screw rod and the nut, and the clamping jaw position control precision is high, the clamping stability is high, and the structure of the overall clamping assembly is more compact.

[0021] A second roller is sleeved on the middle of the guide rod.

A second roller is sleeved on the middle of the guide rod, and the second roller is located between the first clamping jaw and the second clamping jaw.

[0023] Rollers are sleeved on the middle of the first screw rod and the guide column, which can increase the contact area between the crystal rod and the two clamping jaws, increase the rolling support for the crystal rod during the movement of the crystal rod, and further reduce the friction between the crystal rod and the first screw rod and the roller.

[0027] The guide grooves arranged on both sides of the second screw rod and the pulleys fixed on the tray cooperate with each other. When the tray moves along the second screw rod, the pulleys and the guide grooves guide the tray, which helps the ejection assembly to push out the horizontal crystal rod smoothly and labor-savingly.

[0055] The flip assembly 20 includes a column 21 and a first driving member 22. The column 21 is flippably arranged on the frame 10, and the driving end of the first driving member 22 is transmission-connected to the column 21.

[0056] The clamping assembly 30 includes a first clamping jaw 31, a second clamping jaw 32 and a second driving member 33. The first clamping jaw 31 and the second clamping jaw 32 are arranged on the column 21, and the driving end of the second driving member 33 is transmission-connected with the first clamping jaw 31 and the second clamping jaw 32; the second driving member 33 is configured to drive the first clamping jaw 31 and the second clamping jaw 32 to move away from or approach each other to clamp or release the crystal rod 50.

[0057] The ejection assembly 40 includes a tray 41 and a third driving member (not shown). The tray 40 is movably disposed on the column 21 , and a driving end of the third driving member is drivingly connected to the tray 41 .

[0058] During the process in which the second driving member 33 drives the first clamp 31 and the second clamp 32 to clamp the crystal rod 50 and the first driving member 22 drives the column 21 to flip from a vertical state to a horizontal state, the first clamp 31 and the second clamp 32 continue to clamp the crystal rod 50, and the tray 41 and the column 21 assist in supporting the clamped crystal rod 50; after the first driving member 22 drives the column 21 to flip from a vertical state to a horizontal state, the second driving member 33 drives the first clamp 31 and the second clamp 32 to release the crystal rod 50, and the third driving member drives the tray 41 to move toward the clamping assembly 30 to push the released crystal rod 50 off the column 21.

[0059] Through the cooperation of the flipping assembly 20 and the clamping assembly 30, during the process of flipping the crystal rod, the first clamp 31 and the second clamp 32 continuously clamp the crystal rod. Compared with the method of flipping the crystal rod by pulling the wire rope in the prior art, the crystal rod transfer vehicle of the present application clamps and fixes the crystal rod 50 on the column 21 through the clamping assembly 30, thereby realizing stable and reliable flipping of the crystal rod 50 and greatly improving the safety of flipping and transportation of the crystal rod 50.

[0060] like Figure 1 As shown, as an optional implementation of a flip assembly 20 , the flip assembly 20 also includes a rotating shaft 23 , which is rotatably disposed on the frame 10 , and is fixedly connected to the column 21 , and a driving end of the first driving member 22 is transmission-connected to the rotating shaft 23 .

[0061] Specifically, two bearing seats 24 are spaced apart on the frame 10 , and both ends of the rotating shaft 23 are rotatably mounted on the two bearing seats 24 . The rotating shaft 23 is fixedly connected to the column 21 via a key.

[0063] The first driving member 22 drives the rotating shaft 23 to rotate, thereby driving the column 21 fixed on the rotating shaft to flip to a vertical state or a horizontal state, providing a flip assembly 20 with a simple structure, small space occupation, and stable and reliable flipping.

[0064] As an optional embodiment of a clamping assembly 30, the clamping assembly 30 also includes a first screw rod 34, a first nut and a second nut.

The first clamping jaw 31 and the second clamping jaw 32 are respectively fixed on the first nut and the second nut.

[0065] The first nut and the second nut are respectively wound around the two ends of the first screw rod 34. When the first screw rod 34 rotates, the first nut and the second nut move away from or approach each other on the first screw rod 34, that is, the first clamping jaw 31 fixedly arranged on the first nut and the second clamping jaw 32 fixedly arranged on the second nut move away from or approach each other. The first clamping jaw 31 and the second clamping jaw 32 are moved closer to or away from each other by the transmission mode of the screw rod and the nut, and the clamping jaw position control precision is high, the clamping stability is high, and the structure of the overall clamping assembly is more compact.

[0066] Optionally, a first roller 36 is sleeved in the middle of the first screw rod 34, and the first roller 36 is located between the first clamping jaw 31 and the second clamping jaw 32. The first roller 36 is sleeved in the middle of the first screw rod 34, and when the crystal rod enters between the first clamping jaw 31 and the second clamping jaw 32 in a vertical state or is pushed outward in a horizontal state, rolling friction occurs between the crystal rod and the first roller 36, which can prevent excessive friction during movement from damaging the crystal rod.

[0067] like Figure 2 and Figure 3 As shown, as an optional embodiment of a clamping assembly 30, the clamping assembly 30 also includes a guide rod 35, which is passed between the first clamping jaw 31 and the second clamping jaw 32 to provide guidance for the first clamping jaw 31 and the second clamping jaw 32 to move closer to or farther away from each other.

[0068] A guide rod 35 is provided between the first clamping jaw 31 and the second clamping jaw 32 to provide guidance for the first clamping jaw 31 and the second clamping jaw 32 to move closer to or farther away from each other, thereby further improving the stability and reliability of clamping.

[0069] Optionally, a second roller 37 is sleeved in the middle of the guide rod 35, and the second roller 37 is located between the first clamp 31 and the second clamp 32. The second roller 37 is sleeved in the middle of the guide rod 35, and when the crystal rod enters between the first clamp 31 and the second clamp 32 in a vertical state or is pushed outward in a horizontal state, rolling friction occurs between the crystal rod and the second roller 37, which can prevent excessive friction from damaging the crystal rod during movement.

[0070] Of course, in order to increase the contact area between the crystal rod and the two clamping jaws, increase the rolling support of the crystal rod during the movement of the crystal rod, and further reduce the friction between the crystal rod and the first screw rod and the roller, rollers can also be set in the middle of the first screw rod 34 and the guide rod 35 at the same time, that is, the middle of the first screw rod 34 is sleeved with a first roller 36, and the first roller 36 is located between the first clamping jaw 31 and the second clamping jaw 32; the middle of the guide rod 35 is sleeved with a second roller 37, and the second roller 37 is located between the first clamping jaw 31 and the second clamping jaw 32.

[0071] See also Figure 2 and Figure 3 As shown, as an optional embodiment of an ejection assembly 40, the ejection assembly 40 also includes a second screw rod 42 and a third nut.

[0072] The tray 41 is fixedly arranged on the third nut, and the tray 41 is reciprocated on the column 21 with high efficiency and high precision through the coordinated transmission mode of the screw nut.

[0073] As an optional embodiment of the ejection assembly 40, the ejection assembly 40 also includes a guide groove 43 and a pulley 44. The guide groove 43 is arranged on both sides of the second screw rod 42 along the extension direction of the column 21, and the pulley 44 is fixed on the tray 41. When the third driving member drives the tray 41 to move along the second screw rod 42, the pulley 44 rolls along the guide groove 43.

[0074] The guide grooves 43 arranged on both sides of the second screw rod 42 and the pulley 44 fixed on the tray 41 cooperate with each other. When the tray 41 moves along the second screw rod 42, the pulley 44 and the guide grooves 43 guide the tray 41, which helps to push out the crystal rod in a horizontal state gradually, smoothly and labor-savingly.

[0075] In order to further improve the stability and reliability of the flipping of the crystal rod 50, the crystal rod transfer vehicle also includes a first support roller 60, which is arranged at the connection between the ejection assembly 40 and the clamping assembly 30, and is used to support the middle part of the crystal rod 50 during the flipping process.

[0081] Optionally, the rotating handle or the electric wrench can be removed relative to each screw rod. To facilitate the storage of the rotating handle or the electric wrench, the crystal rod transport vehicle further includes a tool box 80 disposed on the vehicle frame 10 .

[0082] like Figure 1 As shown, the first driving member 22 is an electric wrench 221 or a rotating handle 222 . When operating the flip assembly 20 , the electric wrench 221 or the rotating handle 222 can be selected.

[0091] See also Figure 1 , Figure 5 and Figure 6 As shown, the specific working principle of the crystal rod transfer vehicle proposed in this application is:

[0092] Receiving crystal rods: Push the crystal rod transfer vehicle to the bottom of the auxiliary furnace chamber of the single crystal furnace. At this time, the column 21 of the crystal rod transfer vehicle is in a vertical state, and the first clamp 31 and the second clamp 32 are in an open state. The silicon rod in the auxiliary furnace chamber of the single crystal furnace in a vertical state passes through the first clamp 31 and the second clamp 32 and is released onto the tray 41. The middle part of the crystal rod 50 is located between the first clamp 31 and the second clamp 32. The second driving member 33 drives the first clamp 31 and the second clamp 32 to move closer to each other to clamp and fix the crystal rod 50. The tray 41 and the column 21 assist in supporting the clamped crystal rod 50, and the receiving of the crystal rod (such as Figure 5 status shown).

[0093] Crystal rod flipping: The first driving member 22 drives the rotating shaft 23 to rotate, thereby driving the column 21 to flip 90° counterclockwise (with Figure 5 The state shown in FIG. 1 is taken as the standard), so that the clamped crystal rod 50 is turned over to Figure 6 In the horizontal state shown, during the flipping process, the first clamp 31 and the second clamp 32 always clamp the crystal rod 50 and fix it on the column 21.

[0094] Crystal rod pushing: After the crystal rod 50 is turned to a horizontal state, the first clamp 31 and the second clamp 32 release the crystal rod 50 on the column 21, and the third driving member drives the tray 41 to move toward the clamping assembly 30 (i.e. Figure 6 From right to left in the figure) to push the crystal rod 50 from the column 21 to the subsequent process.

[0095] The above embodiments are only to illustrate the basic principles and characteristics of the present application. The present application is not limited by the above examples.
