Description

Technical Field

[0001] The present application relates to the field of single crystal pulling, and in particular to an error-proofing mechanism and a barrel transporting trolley. Background Art

[0002] After the lifting mechanism lifts the empty barrel (usually a quartz barrel) out of the single crystal furnace, it lowers the barrel onto the barrel transport trolley, and then clamps the barrel with the clamp on the barrel transport trolley.

[0003] The barrel transport trolley moves the barrel to the bottom of the feeding hopper for feeding. To prevent the hanger on the top of the barrel from blocking the silicon material and to ensure that the silicon material dropped from the feeding hopper falls smoothly into the barrel, the orientation of the barrel must meet the predetermined requirements.

[0004] Due to the heavy weight of the barrel, it is very difficult to adjust the barrel's direction manually after the barrel is transferred to the bottom of the feeding hopper by the barrel transport trolley. Therefore, it is necessary to adjust the barrel's direction in advance when the barrel is lowered to a predetermined height and is in a suspended state. However, at present, the barrel's direction adjustment and clamping are all completed by workers manually. When the barrel is lowered to the trolley, workers often forget to adjust the barrel's direction. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides an error prevention mechanism, which adopts the following technical solutions:

[0006] An error prevention mechanism comprises a pull rod, a pressure bearing part, a transmission connection part, a slide rail and an error prevention limit part, wherein:

[0007] The error-proofing limit part is slidably connected to the slide rail and can slide horizontally along the slide rail;

[0008] The first end of the pull rod is connected to the bottom of the error prevention limit part through the transmission connection part;

[0009] The pressure bearing part is connected with the pull rod;

[0010] The pressure-bearing portion is configured to pull down the pull rod when under pressure, and the pull rod drives the error-proofing limit portion to slide horizontally along the slide rail toward the first side of the error-proofing mechanism through the transmission connection portion.

[0011] The error prevention mechanism provided by the present application is set on the barrel transport trolley. When the hoisting mechanism lowers the barrel toward the barrel transport trolley to a predetermined height, the flange on the barrel presses against the pressure-bearing part. After the pressure-bearing part is pressed, the pull rod is pulled down. The pull rod drives the error prevention limit part to slide horizontally along the slide rail toward the barrel through the transmission connection part. When the direction of the barrel does not match the predetermined direction, the error prevention limit part contacts the barrel and pushes the barrel, which eventually causes the barrel to be unable to be clamped by the clamp. In this way, the worker can be reminded to adjust the direction of the barrel.

[0012] In some embodiments, the error prevention mechanism also includes an elastic reset part, and the second end of the pull rod is connected to the top of the elastic reset part; when the pressure-bearing part is under pressure to pull the pull rod down, the elastic reset part is compressed; when the pressure-bearing part loses pressure, the elastic reset part rebounds to push the pull rod up and reset.

[0013] By arranging the elastic reset part, the pull rod can be automatically rebounded and reset when the pressure-bearing part loses pressure.

[0014] In some embodiments, the pressure-bearing portion includes a pressure block, which is fixed on the pull rod. When the pressure block is under pressure, it pulls down the pull rod.

[0015] The pressure block is directly fixed on the pull rod, making the structure of the pressure-bearing part more simple and compact.

[0016] In some embodiments, the pressure-bearing part includes a pressure block and a connecting rod, wherein the first end of the connecting rod is connected to the top of the elastic reset part, and the pressure block is arranged at the second end of the connecting rod; when the pressure block is under pressure, the elastic reset part is pressed down through the connecting rod, so that the elastic reset part shrinks under pressure and then pulls down the pull rod.

[0017] Since the connecting rod and the pull rod are both connected to the top of the elastic reset part, the force on the elastic reset part is more uniform, which prevents the top of the elastic reset part from tilting due to uneven force, causing the pull rod to tilt.

[0018] In some embodiments, the elastic reset portion includes a base, a pressure plate and a spring, wherein: the second end of the pull rod is connected to the pressure plate; the upper end of the spring abuts against the pressure plate, and the lower end of the spring abuts against the base.

[0019] The invention provides an elastic reset part with a simple structure. When the pressure-bearing part is pressed and the pull rod is pulled down, the pull rod presses down the pressure-bearing plate, and the pressure-bearing plate descends to drive the spring to contract. When the pressure-bearing part loses pressure, the spring rebounds, thereby driving the pressure-bearing plate and the pull rod to rise and reset.

[0020] In some embodiments, the base includes a top plate and a bottom plate arranged up and down, a guide hole is provided on the top plate, the second end of the pull rod passes through the guide hole and is fixedly connected to the pressure plate, the pressure plate is located below the top plate, and the lower end of the spring abuts against the bottom plate.

[0021] By setting the base, the base can guide the lifting of the second end of the pull rod, thereby preventing the second end of the pull rod from tilting.

[0022] In some embodiments, the anti-error mechanism further includes a linear bearing, the pull rod passes through the linear bearing, and the linear bearing is used to guide the lifting and lowering of the pull rod.

[0023] By setting up a linear bearing, the support and lifting guide of the pull rod are achieved, preventing the pull rod from tilting during the lifting process.

[0024] In some embodiments, the transmission connection part includes a connecting rod, which is arranged at an angle, and the first end of the connecting rod is hinged to the first end of the pull rod, and the second end of the connecting rod is hinged to the bottom of the anti-error limit part; when the pull rod is pulled down, the connecting rod is driven to rotate, so as to drive the anti-error limit part to slide horizontally along the sliding rail toward the first side of the anti-error mechanism.

[0025] By adopting the connecting rod drive method, a small lifting and lowering movement of the pull rod can drive the anti-error mechanism to produce a larger translation, ensuring the pushing effect of the anti-error limit part on the barrel.

[0026] In some embodiments, the transmission connection part includes a guide plate and a guide block, wherein: the guide plate is fixedly connected to the bottom of the anti-error limit part in the vertical direction, and an arc-shaped guide groove is arranged on the guide plate; the guide block is arranged at the first end of the pull rod and slides through the guide groove; when the pull rod is pulled down, it drives the guide block to slide in the guide groove, and when the guide block slides, it pushes the guide plate, so that the anti-error limit part slides horizontally along the slide rail toward the first side of the anti-error mechanism.

[0027] The driving force and stability of the transmission connection part on the anti-error limit part can be improved by adopting the method of driving in coordination with the guide plate and the guide block.

[0028] In some embodiments, the anti-error limit portion includes a connecting plate and an anti-error limit plate, wherein: the connecting plate is slidably connected to the slide rail; the first end of the anti-error limit plate is connected to the connecting plate, and the second end of the anti-error limit plate is provided with a card slot.

[0029] When the transmission connection part drives the connection plate and the error prevention limit plate to slide toward the barrel, the clamping groove at the second end of the error prevention limit plate is clamped and positioned on the barrel, for example, on the hanger at the top of the barrel. In this way, the error prevention limit plate can be prevented from slipping when pushing the barrel, detaching from the barrel, and causing error prevention failure.

[0030] The present application also provides a barrel transport trolley, which comprises a trolley body, a support frame, a clamp and any one of the above-mentioned error prevention mechanisms, wherein:

[0031] The support frame is arranged on the vehicle body;

[0032] The hoop and the error prevention mechanism are installed on the support frame, the hoop is located below the error prevention mechanism, a barrel placement space is provided on the first side of the error prevention limiter, and the hoop is used to fix the barrel in the barrel placement space;

[0033] When the barrel is lowered to the barrel placement space and reaches a predetermined height, the flange on the barrel is pressed onto the pressure-bearing part, so that the error-proof limit part slides toward the barrel;

[0034] When the orientation of the barrel does not match the predetermined orientation, the error-proof limiting portion contacts the barrel and pushes the barrel, so that the barrel is away from the clamp.

[0035] The barrel transport trolley provided by the present application, when the hoisting mechanism lowers the barrel toward the barrel transport trolley to a predetermined height, the flange on the barrel presses against the pressure-bearing part, and the pressure-bearing part pulls down the pull rod after being pressed, and the pull rod drives the error-proofing limit part to slide horizontally along the slide rail toward the barrel through the transmission connection part. When the direction of the barrel does not match the predetermined direction, the error-proofing limit part contacts the barrel and pushes the barrel, eventually causing the barrel to be unable to be clamped by the clamp, so that the worker can be reminded to adjust the direction of the barrel.

[0050] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] Figure 1The structure of the error prevention mechanism in one embodiment of the present application is shown. Figure 2 The structure of the error prevention mechanism in another embodiment of the present application is shown. The error prevention mechanism 10 of the present application includes a pull rod 1, a pressure bearing portion 2, a transmission connection portion 3, a slide rail 4 and an error prevention limit portion 5, wherein:

[0052] The anti-error limit part 5 is slidably connected to the slide rail 4 and can slide horizontally along the slide rail 4. The first end (such as the upper end) of the pull rod 1 is connected to the bottom of the anti-error limit part 5 via the transmission connection part 3. The pressure-bearing part 2 is connected to the pull rod 1. The pressure-bearing part 2 is configured to pull down the pull rod 1 when under pressure, and the pull rod 1 drives the anti-error limit part 5 to slide horizontally along the slide rail 4 toward the first side of the anti-error mechanism 5 through the transmission connection part 3.

[0053] The method of using the error prevention mechanism of the embodiment of the present application is as follows:

[0054] The error prevention mechanism 10 is installed on the barrel transport trolley. After the lifting mechanism lifts the barrel out of the single crystal furnace, it is lifted to the top of the first side (such as the left side) of the error prevention mechanism 5. Subsequently, the lifting mechanism lowers the barrel. When the barrel is lowered to a predetermined height, the flange on the barrel is pressed against the pressure-bearing part 2. After the pressure-bearing part 2 is pressed, the pull rod 1 is pulled down. The pull rod 1 drives the error prevention limit part 5 to slide horizontally along the slide rail 4 toward the barrel through the transmission connection part 3. The sliding direction of the error prevention limit part 5 is as shown in FIG. Figure 1 and Figure 2 The X-axis direction.

[0055] When the orientation of the barrel does not match the predetermined orientation, the error-proofing limiter 5 will contact the barrel (for example, it will be stuck on the hanger at the top of the barrel) and push the barrel after it moves into place, causing the barrel to deviate significantly from the predetermined lowering position, and eventually causing the barrel to be unable to be clamped by the clamp on the barrel transport trolley. In this way, when the worker subsequently clamps the barrel with the clamp, he is reminded to adjust the orientation of the barrel because he cannot clamp the barrel. When the orientation of the barrel matches the predetermined orientation, the error-proofing limiter 5 will not contact the barrel after it moves into place, or even if it contacts the barrel, it will not cause the barrel to deviate significantly from the predetermined lowering position, thereby not affecting the normal clamping of the barrel by the clamp.

[0056] like Figure 1 and Figure 2 As shown, optionally, the error prevention mechanism in the embodiment of the present application further includes an elastic reset portion 6, and the second end (such as the lower end) of the pull rod 1 is connected to the top of the elastic reset portion 6. When the pressure-bearing portion 2 is pressed to pull down the pull rod 1, the elastic reset portion 6 is compressed. When the barrel is separated from the pressure-bearing portion 21, the pressure-bearing portion 21 loses pressure, thereby releasing the pull-down of the pull rod 1, and the elastic reset portion 6 loses pressure and rebounds, thereby pushing the pull rod 1 to automatically rise and reset.

[0057] Optionally, the pressure-bearing part 2 includes a pressure block 21 and a connecting rod 22, wherein the first end (such as the lower end) of the connecting rod 22 is connected to the top of the elastic reset part 6, and the pressure block 21 is arranged at the second end (such as the upper end) of the connecting rod. When the pressure block 21 is under pressure, the elastic reset part 6 is pressed down through the connecting rod 22, so that the elastic reset part 6 is compressed and contracts, thereby pulling the pull rod 1 downward. Since the connecting rod 22 and the pull rod 1 are both connected to the top of the elastic reset part 6, the force on the elastic reset part 6 is more uniform, which prevents the top of the elastic reset part 6 from tilting due to uneven force, causing the pull rod 1 to tilt.

[0058] Of course, the connecting rod 22 may not be provided, and the pressing block 21 may be directly fixed on the pull rod 1. In this way, the structure of the pressure-bearing part 2 may be simpler and more compact.

[0059] like Figure 1 As shown, optionally, the elastic reset portion 6 includes a base 61, a pressure plate 62 and a spring 63, wherein the second end (such as the lower end) of the pull rod 1 is connected to the pressure plate 62. The upper end of the spring 63 abuts against the pressure plate 62, and the lower end of the spring 63 abuts against the base 61. When the pressure-bearing portion 2 is pressed and the pull rod 1 is pulled down, the pull rod 1 presses down the pressure plate 62, and the pressure plate 62 descends to drive the spring 63 to contract. When the pressure-bearing portion 2 loses pressure, the spring 63 loses pressure and rebounds, thereby pushing the pull rod 1 upward through the pressure plate 62 to rise and reset. In order to improve the smoothness of the lifting and lowering of the pressure plate 62, two springs 63 can be arranged side by side.

[0060] Optionally, the base 61 includes a top plate and a bottom plate arranged up and down, a guide hole is arranged on the top plate, the second end of the pull rod 1 passes through the guide hole and is fixedly connected to the pressure plate 62, the pressure plate 62 is located below the top plate, and the lower end of the spring 63 abuts against the bottom plate. The guide hole on the top plate guides the lifting of the second end of the pull rod 1 to prevent the second end of the pull rod 1 from tilting during the lifting process.

[0061] like Figure 1 and Figure 2 As shown, optionally, the anti-error mechanism in the embodiment of the present application further includes a linear bearing 7, and the pull rod 1 passes through the linear bearing 7. The linear bearing 7 is used to guide the lifting of the pull rod 2, thereby improving the lifting stability of the pull rod 1 and preventing the pull rod 1 from tilting during the lifting process.

[0062] like Figure 1As shown, optionally, the transmission connection part 3 includes a connecting rod 31, the connecting rod 31 is tilted, the first end of the connecting rod 31 is hinged to the first end (such as the upper end) of the pull rod 1, and the second end of the connecting rod 31 is hinged to the bottom of the anti-error limit part 5. When the pull rod 1 is pulled down, the connecting rod 31 is driven to rotate (such as clockwise), thereby driving the anti-error limit part 5 to slide horizontally along the slide rail 4 toward the first side of the anti-error mechanism 5. When the pull rod 1 rises and resets, the connecting rod 31 is driven to rotate in the opposite direction (such as counterclockwise), thereby driving the anti-error limit part 5 to slide horizontally along the slide rail 4 away from the first side of the anti-error mechanism 5 and reset.

[0063] By adopting the driving mode of the connecting rod 31, a small lifting and lowering movement of the pull rod 1 can drive the anti-error mechanism 5 to produce a large translation, ensuring that the error limiting part 5 can push the barrel to move.

[0064] like Figure 2 As shown, optionally, the transmission connection part 3 includes a guide plate 32 and a guide block 33, wherein: the guide plate 32 is fixedly connected to the bottom of the anti-error limit part 5 in the vertical direction, and an arc-shaped guide groove 34 is provided on the guide plate 32. The guide block 33 is provided at the first end (such as the upper end) of the pull rod 1, and is slidably penetrated in the guide groove 34. When the pull rod 1 is pulled down, the guide block 33 is driven to slide in the guide groove 34, and the guide block 33 pushes the guide plate 32 when sliding, so that the anti-error limit part 5 slides horizontally along the slide rail 4 toward the first side of the anti-error mechanism 5. When the pull rod 1 rises and resets, it drives the guide block 33 to slide in the guide groove 34 in the opposite direction, and the guide block 33 pushes the guide plate 32, thereby driving the anti-error limit part 5 to slide horizontally along the slide rail 4 away from the first side of the anti-error mechanism 5 and reset.

[0065] By adopting the cooperative driving mode of the guide plate 32 and the guide block 33, the driving force and stability of the transmission connection part 3 on the anti-error limit part 5 can be improved, and finally the pushing effect of the anti-error limit part 5 on the barrel can be improved.

[0066] like Figure 1 and Figure 2 As shown, optionally, the anti-error limit part 5 includes a connecting plate 51 and an anti-error limit plate 52, wherein the connecting plate 51 is slidably connected to the slide rail 4, the first end of the anti-error limit plate 52 is connected to the connecting plate 51, and the second end of the anti-error limit plate 52 is provided with a card slot 53.

[0067] When the transmission connection part 3 drives the connection plate 51 and the anti-error limit plate 52 to slide toward the barrel, the clamping groove 53 at the second end of the anti-error limit plate 52 is clamped and positioned on the barrel, for example, on the hanger at the top of the barrel. In this way, the anti-error limit plate 52 can be prevented from slipping when pushing the barrel, detaching from the barrel, and causing the anti-error failure.

[0068] The present application also provides a barrel transport trolley, such as Figure 3 to Figure 4As shown, the barrel transport trolley includes a trolley body 20, a support frame 30, a clamp 40 and an error prevention mechanism 10 provided in any of the above embodiments, wherein:

[0069] The support frame 30 is disposed on the vehicle body 20 .

[0070] The clamp 40 and the anti-error mechanism 10 are installed on the support frame 30. The clamp 40 is located below the anti-error mechanism 10. A barrel placement space is provided on the first side (for example, the left side) of the anti-error limit portion 5. The clamp 40 is used to fix the barrel 100 in the barrel placement space.

[0071] The barrel 100 is lowered to the barrel placement space by the lifting mechanism, and when it reaches a predetermined height, the flange 101 on the barrel 100 is pressed onto the pressure-bearing part 2, for example, onto the pressure plate 21 of the pressure-bearing part 2, so that the anti-error limit part 5 slides toward the barrel 100.

[0072] When the orientation of the barrel 100 is inconsistent with the predetermined orientation, the error-proof limiting portion 5 contacts the barrel 100 and pushes the barrel 100 , so that the barrel 100 is away from the clamp 4040 .

[0073] like Figure 4 As shown, when the anti-error limit part 5 includes a connecting plate 51 and an anti-error limit plate 52, when the orientation of the barrel 100 is inconsistent with the predetermined orientation, the slot 53 at the second end of the anti-error limit plate 52 is clamped on the hanger 102 of the barrel 100. With the further translation of the anti-error limit part 5, the barrel 100 moves away from the clamp 4040 until it completely deviates from the clamp 40.

[0074] Since the barrel 100 has completely deviated from the clamp 40, after the hoisting mechanism lowers the barrel 100 into place, when the worker uses the clamp 40 to clamp the barrel 100, the clamp 40 cannot clamp the barrel, thereby reminding the worker to adjust the direction of the barrel 100 in time. At this time, the hoisting mechanism has not yet separated from the barrel 100, so the hoisting mechanism can lift the barrel 100 again, and after the worker completes the adjustment of the direction of the barrel 100, the hoisting mechanism lowers the barrel 100 onto the vehicle body 20 again.

[0075] The above description of the present application is sufficiently detailed and has certain particularities. Those skilled in the art should understand that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, not by the above description in the embodiments. Moreover, the embodiments mentioned in the present application are not limited to being implemented individually, and some embodiments can also be implemented in combination.
