The application provides a silicon rod location cutting device, include: a mounting base 100 for receiving the silicon rod 1; the transverse adjusting mechanism 200 is connected with the mounting seat 100 and can drive the mounting seat 100 to move along a first direction; the longitudinal adjusting mechanism 300 is connected with the mounting seat 100 and can drive the mounting seat 100 to move along a second direction, and the second direction is perpendicular to the first direction; the cutting mechanism 400 is arranged above the mounting seat 100 and is used for cutting the silicon rod 1.

The mounting seat 100 is used for providing a stable and reliable placement position for the silicon rod 1.

Optionally, a fixing mechanism (not shown) is provided on the mount 100 for fixing the silicon rod 1. After the silicon rod 1 is fed, the fixing mechanism can fix the silicon rod 1 and prevent the silicon rod 1 from moving on the mounting seat 100 or separating from the mounting seat 100.

The fixing mechanism can be a clamping jaw, and can clamp the silicon rod 1 so as to fix the silicon rod 1 on the mounting seat 100; the fixing mechanism can also be a sucker, and the silicon rod 1 can be adsorbed on the mounting seat 100 through negative pressure; the fixing mechanism can also be a clamping groove, at least part of the silicon rod 1 can extend into the clamping groove, and the groove wall of the clamping groove can play a role in limiting the displacement or inclination of the silicon rod 1. The specific configuration of the securing mechanism is not limited in this application.

The lateral adjustment mechanism 200 and the longitudinal adjustment mechanism 300 are both connected to the mount 100, and since the second direction is perpendicular to the first direction, the mount 100 can be moved at any position in a plane formed by the first direction and the second direction by the lateral adjustment mechanism 200 and the longitudinal adjustment mechanism 300, and of course, the movement range of the mount 100 is limited by the adjustment ranges of the lateral adjustment mechanism 200 and the longitudinal adjustment mechanism 300.

In a specific embodiment, referring to fig. 3, the first direction is a left-right direction, the second direction is a front-back direction, and referring to fig. 1 and 2 in combination, a plane formed by the first direction and the second direction is a horizontal plane. At this time, the horizontal position of the mount 100 can be adjusted by the cooperation of the horizontal adjustment mechanism 200 and the vertical adjustment mechanism 300.

It is easy to understand that when the mounting seat 100 is loaded with the silicon rod 100 to be cut, the position of the silicon rod 1 can be adjusted by adjusting the position of the mounting seat 100, so that the silicon rod 1 is aligned with the cutting mechanism 400, and the accuracy of cutting the silicon rod 1 is further ensured.

In one embodiment, the mounting base 100 is disposed on the lateral adjustment mechanism 200, and the lateral adjustment mechanism 200 is disposed on the longitudinal adjustment mechanism 300; at this time, the lateral adjustment mechanism 200 can directly drive the mount 100 to move along the first direction, and the longitudinal adjustment mechanism 300 can drive the lateral adjustment mechanism 200 to further drive the mount 100 to move along the second direction.

In another embodiment, the mounting base 100 is provided on the longitudinal adjustment mechanism 300, and the longitudinal adjustment mechanism 300 is provided on the lateral adjustment mechanism 200; at this time, the longitudinal adjustment mechanism 300 can directly drive the mount 100 to move along the second direction, and the lateral adjustment mechanism 200 can drive the longitudinal adjustment mechanism 300 and thus the mount 100 to move along the first direction.

The specific mounting manner of the lateral adjustment mechanism 200, the longitudinal adjustment mechanism 300, and the mounting base 100 is not limited, as long as the mounting base 100 can be driven by the lateral adjustment mechanism 200 and the longitudinal adjustment mechanism 300, and can move in both the first direction and the second direction.

In addition, in the silicon rod positioning and cutting device provided by the application, the cutting mechanism 400 is disposed above the mounting seat 100, and at this time, at least a cutting member (such as a cutter or a wire mesh 410 described below) for cutting the silicon rod 1 is suspended above the mounting seat 100.

After the silicon rod 1 is placed in the mounting seat 100, if the relative position of the silicon rod 1 and the cutting piece is not accurate, the cutting piece cannot normally contact the silicon rod 1 or realize cutting of the required position of the silicon rod 1, the position of the silicon rod 1 can be adjusted by the transverse adjusting mechanism 200 and the longitudinal adjusting mechanism 300 so that the silicon rod 1 is aligned with the cutting piece.

After the silicon rod 1 and the cut piece are aligned with each other, the cut piece can cut the silicon rod 1 from top to bottom. At this time, the cutting member may be moved toward the silicon rod 1, the silicon rod 1 may be moved toward the cutting member, or the silicon rod 1 and the cutting member may be moved toward each other in synchronization.

Because the silicon rod 1 is cut from top to bottom, the cutting force of the silicon rod 1 is more stable, the use loss of a cutting piece can be reduced, and the cutting efficiency can be improved.

In summary, the relative positions of the silicon rod 1 and the cutting mechanism 400 can be adjusted by the transverse adjusting mechanism 200 and the longitudinal adjusting mechanism 300, so that the silicon rod 1 is aligned to the cutting mechanism 400, and the cutting effect of the silicon rod 1 is improved and ensured. Further, the silicon rod 1 is cut from top to bottom, so that the cutting state of the silicon rod 1 is more stable, and the cutting effect is better.

To facilitate the mount 100 to accurately receive the silicon rod 1, in one embodiment, the mount 100 includes: the silicon rod is contacted with the silicon rod 1 at one end of the seat 110, and a limiting block 111 is arranged at the other end of the seat 110; the bearing seat 120, the transverse adjusting mechanism 200 and the longitudinal adjusting mechanism 300 are connected with the bearing seat 120, and the bearing seat 120 is provided with a limiting hole 121; the limiting block 111 is inserted into the limiting hole 121, so that the connecting seat 110 and the supporting seat 120 can be connected, the transverse adjusting mechanism 200 drives the silicon rod 1 to move along the first direction, and the longitudinal adjusting mechanism 300 drives the silicon rod 1 to move along the second direction.

In this embodiment, the mount 100 is formed of two parts that are detachably connected. Wherein the socket 120 is relatively fixedly mounted on the lateral adjustment mechanism 200 and the longitudinal adjustment mechanism 300, and the socket 110 is detachably connected with the socket 120. Thus, when the silicon rod 1 needs to be fed and discharged, the seat 110 can be removed from the seat 120, the silicon rod 1 which has been cut can be transferred by using the seat 110, or the silicon rod 1 to be cut can be taken in by using the seat 110. After the silicon rod 1 to be cut is loaded on the socket 110, the socket 110 is mounted on the socket 120 through the stopper 111 and the stopper hole 121.

By providing the mounting base 100 composed of two parts detachably connected, the loading position of the silicon rod 1 can be further calibrated. It is easy to understand that the limiting block 111 and the limiting hole 121 have a corresponding plugging relationship, so that the limiting block 111 is inserted into the limiting hole 121, and the connection between the socket 110 and the socket 120 in a uniform and accurate state can be ensured, and the uniform and accurate position of the silicon rod 1 on the mounting seat 100 can be ensured. Meanwhile, when the structural precision of the limiting block 111 and the limiting hole 121 is higher, after the limiting block 111 is inserted into the limiting hole 121, the limiting block is limited by the wall of the limiting hole 121, the inserting position of the limiting block 111 is fixed and stable, and the state of the silicon rod 1 on the mounting seat 100 in the cutting process can be further ensured to be stable.

The specific configurations of the stopper 111 and the stopper hole 121 are not limited in this application, as long as they can be detachably connected with the socket 120 through a plug-in fit.

The number of the limiting blocks 111 and the limiting holes 121 is not limited in the present application.

Optionally, the socket 110 is provided with a fixing mechanism. The specific configuration of the fixing structure is referred to above and will not be described here.

Optionally, the silicon rod 1 is glued to the socket 110 by means of epoxy glue.

In one embodiment, the limiting block 111 is in a shape of a truncated cone, and the limiting hole 121 is a tapered hole; the limiting block 111 and the limiting hole 121 are both in Morse taper, and the taper of the limiting block 111 is consistent with that of the limiting hole 121.

Referring to fig. 3 and fig. 4, in the illustrated embodiment, the limiting hole 121 is disposed on the upper surface of the seat 120, and the aperture of the limiting hole 121 gradually decreases from top to bottom; the limiting block 111 is disposed on the lower surface of the seat 110, and the outer diameter of the limiting block 111 gradually decreases from top to bottom. At this time, the aperture of the upper portion of the limiting hole 121 is larger, so that the insertion of the limiting block 111 is facilitated, and the movement of the limiting block 111 to the bottom of the limiting hole 121 can be guided; after the limiting block 111 is inserted in place, the inner wall of the limiting hole 121 is attached to the outer wall of the limiting block 111, and the mounting precision of the seat 110 and the seat 120 is high and the mounting stability is high.

It should also be explained that Morse taper is an international standard of taper for an interference fit to achieve accurate positioning. By utilizing the principle of friction force, certain torque can be transmitted between the seat 110 and the seat 120, and the seat 110 and the seat 120 are in taper fit, so that the seat 110 and the seat 120 can be conveniently disassembled and assembled, and have a stable connection state after being connected.

Alternatively, when the socket 110 and the socket 120 are installed, the socket 110 is inserted into the socket 120 after the socket 110 is lifted by a crane, a robot, or other handling equipment. Because the taper of the limiting block 111 and the limiting hole 121 is precisely machined, the two conical surfaces can be completely attached under the action of gravity in the process that the limiting block 111 enters the limiting hole 121 from top to bottom, so that the mounting precision of the seat 110 and the seat 120 is very high.

Optionally, one of the seat 110 and the seat 120 is provided with a positioning pin 112, and the other is provided with a positioning pin hole; so that the positioning pin 112 is aligned with the positioning pin hole to facilitate the insertion of the stopper 111 into the stopper hole 121.

It is easy to understand that the manufacturing precision and the matching precision of the positioning pin 112 and the positioning pin hole are very high, so that the positioning pin 112 is aligned to the positioning pin hole, which is beneficial to ensuring the accurate relative positions of the seat 110 and the seat 120, and is more convenient for the seat 110 to be accurately connected with the seat 120. Meanwhile, after the positioning pin 112 is inserted into the positioning pin hole, the two are mutually limited, so that the connection state of the seat 110 and the seat 120 can be further ensured to be stable.

In an embodiment, referring to fig. 3 and 4, the positioning pin 112 is fixedly disposed on the upper surface of the seat 120, and the outer diameter of the upper end of the positioning pin 112 gradually increases from top to bottom; the positioning pin holes are arranged on the lower surface of the seat 110, and the inner diameters of the positioning pin holes are gradually increased from top to bottom; because the top of the locating pin 112 is smaller, the locating pin 112 can conveniently extend into the locating pin hole and can be closely contacted after the locating pin 112 extends into the locating pin hole under the guidance of the locating pin hole.

Optionally, the seat 120 is further provided with an exhaust hole 122, and the exhaust hole 122 is communicated with the limiting hole 121.

One end of the exhaust hole 122 penetrates through the bearing seat 120, and the other end is communicated with the limiting hole 121. In this way, when the limiting block 111 is inserted into the limiting hole 121, air in the limiting hole 121 can be discharged through the air discharge hole 122, so that the phenomenon that the contact between the limiting block 111 and the limiting hole 121 is not tight due to air blocking in the air discharge hole 122 when the silicon rod 1 is installed is avoided.

To optimize the cutting effect, in some embodiments, the cutting fluid is sprayed on the silicon rod 1 during the cutting process, and at this time, the air vent 122 also plays a role of discharging the cutting fluid.

The specific configurations of the lateral adjustment mechanism 200 and the longitudinal adjustment mechanism 300 are not limited in this application. Taking the lateral adjustment mechanism 200 as an example, the lateral adjustment mechanism 200 may be a manual adjustment mechanism, such as a micrometer, a jackscrew, a screw rod, a hand wheel, etc.; the lateral adjustment mechanism 200 may also be an automatic adjustment mechanism, such as an electric cylinder, a linear module, or the like.

The automatic acting piece 234 is a servo motor, and when the servo motor works, the screw rod 231 can be driven to rotate, so that the screw rod nut 232 can move along the screw rod 231 in the first direction.

To define the mounting position of the angular contact bearings 255 in the second bearing seat 256, the inner ring of one of the angular contact bearings 255 facing away from the other angular contact bearing 255 abuts against the other shoulder of the outer circumference of the screw 231, wherein the inner ring of the other angular contact bearing 255 facing away from the other angular contact bearing 255 abuts against the bearing collar 257; the bearing collar 257 is sleeved on the screw rod 231.

Optionally, the cutting mechanism 400 further comprises a spraying component, which is arranged above the mounting seat 100 and is used for spraying the cutting fluid to the silicon rod 1.

The cutting fluid is an auxiliary material consumable product which is necessary to be used in the cutting process of the silicon rod 1. The cutting fluid has suspending capability, so that silicon carbide particles can be suspended, thereby improving cutting efficiency and reducing cutting consumption. The cutting fluid also has dispersing capability, so that silicon carbide particles can be mixed with the cutting fluid more uniformly. The cutting fluid also has lubricating property, and can form a protective film on the surface of the silicon rod, thereby reducing cutting resistance and ensuring the smoothness of the surface of the cut finished product. The cutting fluid also has cooling performance, and can radiate heat and reduce cutting stress.

In the silicon rod positioning and cutting device provided by the application, a cutting piece (such as a wire mesh 410) is arranged above the silicon rod 1 and cuts the silicon rod 1 from top to bottom. In the cutting process, the spraying component sprays cutting fluid from top to bottom, at this moment, the cutting fluid can directly flow into the gap formed by cutting, and then the auxiliary cutting is better, the cutting effect is improved.

The specific structure of the spraying assembly and the specific components of the cutting fluid are in the prior art, and are not repeated here.

Optionally, the cutting mechanism 400 further includes a monitoring assembly 420 disposed above the mounting base 100 for photographing the silicon rod 1.

The monitoring component 420 may be a CCD camera (charge coupled device) or an imager, and the working end of the monitoring component 420 faces the top of the silicon rod 1, so that the top of the silicon rod 1 can be photographed. When the position of the silicon rod 1 is adjusted, the relative positions of the silicon rod 1 and the cutting piece can be confirmed through the monitoring component 420; during the cutting process, the cutting effect may be observed by the monitoring assembly 420.

When the position adjustment of the silicon rod 1 needs to be manually participated, the cutting mechanism 400 further comprises a display screen (not shown) for displaying the shot content of the monitoring assembly 420, so that an operator can conveniently adjust the position of the silicon rod 1 by observing the display screen and confirm whether the silicon rod 1 is aligned with the cutting piece.

Similarly, when the cutting process needs to be observed manually, the cutting mechanism 400 further comprises a display screen for displaying the cutting condition of the silicon rod 1 in real time.

When the adjustment process does not need to be manually performed, the cutting mechanism 400 may not be provided with a display screen, and the monitoring component 420 transmits shooting information to the control system, and the control system calculates relevant parameters and controls the transverse adjustment mechanism 200 and the longitudinal adjustment mechanism 300 to perform adjustment actions. Meanwhile, the cutting process can be monitored only through the control system, and when a problem occurs, the control system sends out an alarm signal to remind an operator to process.

In other embodiments, the monitoring assembly 420 may also be a photoelectric sensor, and a light shielding positioning plate (not shown) is disposed on the top of the silicon rod 1, and when the photoelectric sensor detects the light shielding positioning plate, the silicon rod 1 is installed in place.

Optionally, the silicon rod positioning and cutting device provided by the application further comprises a positioning mechanism 500, which is arranged above the mounting seat 100 and is used for fixing one end of the silicon rod 1 away from the mounting seat 100.

It is easy to understand that the silicon rod 1 has a certain height, and in order to avoid the mount 100 from interfering with cutting, the mount 100 contacts only the bottom of the silicon rod 1 or a part of the lower end of the silicon rod 1. Because the silicon rod 1 is higher, the silicon rod 1 is easy to incline or even topple under the influence of external force and inertia in the moving or cutting process. For this reason, the positioning mechanism 500 is provided to fix the end of the silicon rod 1 away from the mounting base 100, which is beneficial to ensuring that the silicon rod 1 maintains a stable state during the cutting process, thereby improving the cutting effect.

The positioning mechanism 500 may be a clamping jaw, and after the silicon rod 1 is adjusted in place and aligned with the cutting piece, the clamping jaw can clamp at least part of the silicon rod 1, so as to realize the stability of the state of the silicon rod 1. Or, the positioning mechanism 500 may be a suction cup, and after the silicon rod 1 is adjusted in place and aligned with the cutting piece, the suction cup can suck the silicon rod 1, so as to realize the stability of the state of the silicon rod 1. Alternatively, the surface of the positioning mechanism 500 is provided with a groove, and the silicon rod 1 can be locked into the groove, and the state of the silicon rod 1 can be stabilized by the friction and the movement restriction between the groove and the surface of the silicon rod 1.
