By adopting the arrangement mode, the efficiency of the edge skin unloading process can be greatly improved, the overall working efficiency of crystal bar cutting processing is further improved, the assembly space is fully utilized, the overall structure of the edge skin unloading device 5 is very compact, and the overall occupied space of equipment is reduced.

Further, since the specific structures of the first and second side skin unloading assemblies are the same and the mutual matching manner with the first and second head assemblies is also the same, only the first side skin unloading assembly is taken as an example, and the specific structure of the side skin unloading device 5 and the mutual matching manner with the first head assembly are further described in detail.

Specifically, the first centering component 53 in the first side skin unloading component includes a centering beam 533, the centering beam 533 is erected between the first truss 511 and the second truss 512, the first truss 511 and the second truss 512 are provided with first sliding components, two ends of the centering beam 533 are respectively slidably connected with the first truss 511 and the second truss 512 through the first sliding components, and the driving device can drive the centering beam 533 to horizontally move along the first truss 511 and the second truss 512 through the first sliding components. The first slip assembly is preferably a rack and pinion arrangement.

Two sets of second sliding components are arranged on the middle beam 533, and the first clamping jaw 531 and the second clamping jaw 532 are respectively connected with one set of second sliding components and can horizontally move along the extending direction of the middle beam 533 under the driving of the second sliding components. The second slip assembly is preferably a lead screw guide rail structure.

As shown in fig. 21, the first clamping jaw 531 includes an upper clamping jaw and a lower clamping jaw, and the upper clamping jaw and the lower clamping jaw can move up and down along the third direction Z, so as to clamp the edge skin from the upper end and the lower end of the edge skin, thereby unloading the edge skin. The second clamping jaw 532 has the same structure as the first clamping jaw 531, and the first clamping jaw 531 and the second clamping jaw 532 can respectively perform unloading procedures on two edge skins of the crystal bar from two sides of the first head assembly.

Further, as shown in fig. 26, in the present utility model, the side skin unloading device 5 has a remarkable advantage in that, by being matched with the head assembly 43, the side skin unloading device 5 can clamp the side skin and slide laterally along the dividing plane between the ingot and the side skin when unloading the side skin, slide the side skin away from the processed ingot, and then transport the side skin to the side skin collecting device 6.

When unloading the edge skin, the conventional crystal bar cutting equipment is limited by the problems of movement interference of the head assembly 43 and the edge skin unloading device 5, and the like, and can only normally unload the edge skin in a drawing mode. As shown in fig. 27, after the ingot is clamped, the ingot is directly separated from the machined ingot by forward drawing in a direction perpendicular to the dividing plane between the ingot and the ingot by the ingot clamp. Because the crystal bar can constantly spray cooling liquid in the cutting process, the liquid can generate larger surface tension at the dividing surface between the crystal bar and the edge skin, and the crystal bar and the edge skin are tightly adsorbed together, so that the surface tension of water needs to be overcome when the edge skin is separated in a drawing mode, the required force is larger, the difficulty is high, the load of a driving device such as a motor is also larger, the safe and stable operation of the edge skin unloading device 5 is not facilitated, and the edge skin can be damaged.

The side skin unloading device 5 in the utility model can unload the side skin in a lateral sliding manner as shown in fig. 26, the sliding movement can greatly reduce the adverse effect of the surface tension on the side skin unloading process, the force required by the side skin unloading is smaller, the side skin separation process is easier, the load of the driving device is smaller, and the side skin unloading process is more stable and safer.

Specifically, in order to make the cutting unit of the ingot cutting system have the advantages in the aspect of unloading the edge cover, the following technical scheme is adopted:

the cutting unit of the crystal bar cutting system comprises a side skin unloading unit, and the side skin unloading unit can unload the side skin cut off the crystal bar in a lateral sliding mode.

Specifically, as shown in fig. 1 and 22, in the first cutting chamber, the edge skin unloading unit includes a first nose 431 and a second nose 432 in the first nose assembly, and a first truss 511, a second truss 512, a middle cross member 533, a first clamping jaw 531 and a second clamping jaw 532 in the first edge skin unloading assembly, where the first nose 431 and the second nose 432 are arranged side by side, and at least one cutting station is disposed between the first nose 431 and the second nose 432.

In the first step in the process of unloading the edge skin, the first clamping jaw 531 and the second clamping jaw 532 need to be moved to two sides of the first nose assembly respectively, that is, to the outer sides of the first nose 431 and the second nose 432 respectively, so as to avoid the motion interference between the first edge skin unloading assembly and the first nose assembly, the specific setting mode is as follows: the first truss 511 and the second truss 512 are respectively located outside the first head 431 and the second head 432 in the horizontal direction, and the first truss 511, the second truss 512 and the center beam 533 are disposed at positions higher than the heights of the head frames 433 of the first head 431 and the second head 432 in the vertical direction, so that a driving space is formed between the first truss 511 and the second truss 512, an unloading space is formed below the first truss 511, the second truss 512 and the center beam 533, and the driving space is located above the unloading space.

When the first head assembly completes a cutting action, the first head 431 and the second head 432 move to a position close to the base 41 at the same time, at this time, the first head 431 and the second head 432 are located in the unloading space, the middle cross beam 533 can move in the driving space above the unloading space, so as to drive the first clamping jaw 531 and the second clamping jaw 532 to move to the outer sides of the first head 431 and the second head 432 respectively, and the first head 431 and the second head 432 do not generate motion interference.

In the second step, after the first clamping jaw 531 and the second clamping jaw 532 move to the outer sides of the first machine head 431 and the second machine head 432 respectively, the first clamping jaw 531 and the second clamping jaw 532 need to clamp the edge skin cut by the first machine head 431 and the second machine head 432 respectively, and in order to avoid motion interference, the specific setting mode is as follows: the middle parts of the head frames 433 of the first and second heads 431 and 432 are formed with a clamping space, and the first and second clamping jaws 531 and 532 may extend from the outer sides of the first and second heads 431 and 432 to the inner sides of the first and second heads 431 and 432 through the clamping space, thereby clamping the edge skin.

In the third step, after the first clamping jaw 531 and the second clamping jaw 532 clamp the edge skin, in order to achieve "lateral sliding" to unload the edge skin, the first clamping jaw 531 and the second clamping jaw 532 need to move along the first direction X in the clamping space of the nose frame 433 towards the direction away from the feeding assembly 42, and in order to avoid the movement interference between the first clamping jaw 531 and the second clamping jaw 532 and the nose frame 433, the following arrangement is preferred: the first and second heads 431 and 432 have openings 437 formed on the head frame 433 such that the head frame 433 forms a C-shaped structure, and the openings 437 enable the head frame 433 to form a sliding space at a side far from the feeding assembly 42, through which the first and second jaws 531 and 532 can avoid movement interference.

In addition, to further reduce the problem of motion interference that may occur during the unloading of the side skin, the first jaw 531 and the second jaw 532 preferably employ the following motion patterns:

as shown in fig. 23, L1 is the gripping path of the jaws into the handpiece and L2 is the unloading path of the jaws out of the handpiece. The clamping jaw moves to the outer side of the machine head along the first direction X firstly, then moves along the second direction Y, passes through the machine head frame 433 and clamps the edge skin; after clamping the edge skin by the clamping jaw, moving a certain distance along the first direction X towards the opening 437 of the head frame 433, so that the edge skin is slidingly separated from the crystal bar; then moving a distance along the second direction Y towards a direction far away from the crystal bar, so that the edge cover and the crystal bar are arranged in a staggered manner in the second direction Y; finally, the movement is performed in the first direction X toward the opening 437 of the head frame 433 until the head is removed, thereby completing the unloading of the edge skin. This unloading mode is particularly suitable for the case where two or more cutting stations are arranged side by side between the first head 431 and the second head 432, and mutual interference between the stations can be effectively avoided.

In the above preferred embodiment, the nose frame has a one-side opening structure, and the lateral sliding direction during unloading of the side skin is sliding along the first direction X toward the side away from the feeding assembly. In addition, when the frame is a rectangular frame in a shape like a Chinese character 'kou' or other frame structures without a lateral opening structure, a sliding space can be formed between the frame and the cutting station by properly increasing the interval distance between the frame and the cutting station, and at this time, the side skin unloading can slide laterally along the first direction X towards the side far from the feeding assembly or slide laterally towards the side close to the feeding assembly. When two cutting stations are provided between the first head and the second head arranged side by side, a slip space may also be formed between the two cutting stations.

However, the provision of the nose frame in a one-sided opening structure to form a slip space is a more preferred embodiment, since the edge skin collecting means for storing the edge skin is located at the side of the cutting chamber remote from the feeding assembly, so that the path of unloading the edge skin is shorter and the efficiency is higher. The mode of properly increasing the interval distance between the machine head frame and the cutting station is adopted, and the lateral sliding unloading of the edge skin can be realized, but the whole size of the machine head frame is increased, the cost is increased, the stable and miniaturized design of the equipment operation is not facilitated, and the length of an unloading path of the edge skin is increased by a reverse sliding unloading mode, so that the unloading efficiency is not facilitated to be improved.

The slip space is preferably capable of allowing the boule to be completely slipped off the finished ingot during lateral slip, with minimal force required for unloading the boule. Of course, the sliding space can also be set to allow the edge skin to slide and separate from the processed crystal bar part when the edge skin slides and separates from the processed crystal bar part, and after the edge skin slides and separates from the processed crystal bar part, the edge skin is unloaded in a direct drawing mode, so that adverse effects caused by surface tension of a part of water can be reduced, and the effect of unloading the edge skin is improved.

The second head assembly and the second edge skin unloading assembly in the cutting unit of the crystal bar cutting system can be arranged in the same matching mode so as to form the edge skin unloading unit with the same functions and effects.

Further, as shown in fig. 1 to 4, the cutting unit of the ingot cutting system further includes a scrap collecting device 6, and the scrap unloaded by the scrap unloading device 5 may be temporarily stored in the scrap collecting device 6. Preferably, the edge skin collecting device 6 comprises two edge skins which are respectively arranged on one side of the first cutting chamber and one side of the second cutting chamber, which are far away from the feeding component, and respectively cooperate with the first edge skin unloading component and the second edge skin unloading component to receive the edge skins unloaded by the first edge skin unloading component and the second edge skin unloading component, so that the working efficiency of the edge skin unloading procedure is further improved, and the overall processing efficiency of the cutting unit of the crystal bar cutting system is further improved.

The edge skin unloading method involved in the cutting unit 200 is described in detail in connection with the above description of the edge skin unloading device 5 and the edge skin unloading unit.

Taking two cutting stations arranged between a group of machine heads as an example, the two cutting stations are arranged side by side along the extending direction of the first machine head assembly and the second machine head assembly, wherein the first cutting station is far away from the opening 437 of the machine head frame 433, the second cutting station is close to the opening 437 of the machine head frame 433, and the edge skin unloading method specifically comprises the following steps:

Step one, the head assembly 43 moves downwards from top to bottom, after completing the cutting actions of two crystal bars on the first cutting station and the second cutting station, the middle cross beam 533 moves towards the head assembly 43 along the first direction X on the truss main body, so that two clamping jaws in the clamping jaw assembly respectively move to two sides of the head assembly 43, and the positions of the crystal bars and the edge slabs on the first cutting station are aligned in the second direction Y;

step two, two clamping jaws in the clamping jaw assembly move towards the first cutting station along the second direction Y on the centering beam 533 until the two clamping jaws respectively reach positions capable of clamping two side skins of the crystal bar;

step three, after the two clamping jaws clamp the two side skins respectively, the middle beam 533 moves on the truss main body along the first direction X towards the direction away from the head assembly 43 so as to enable the side skins to be slidingly separated from the crystal bars;

step four, after the edge skin and the crystal bar are slipped and separated, the two clamping jaws move on the middle cross beam 533 along the second direction Y towards the direction away from the first cutting station, so that the edge skin and the crystal bar are mutually misplaced and separated in the second direction Y;

fifthly, the middle cross beam 533 drives the clamping jaw assembly for clamping the edge skin to move along the first direction X towards a direction away from the machine head assembly 43, an opening 437 is formed in the machine head assembly 43, and the middle cross beam 533 drives the clamping jaw assembly to move the edge skin out of the machine head assembly 43 through the opening 437;

Step six, the middle cross beam 533 continues to drive the clamping jaw assembly to move, and the side leather is conveyed to the side leather collecting device 6;

step seven, the middle cross beam 533 moves towards the head assembly 43 along the first direction X on the truss main body, so that two clamping jaws in the clamping jaw assemblies respectively move to two sides of the head assembly 43, and the positions of the crystal bars and the edge covers on the second cutting station are aligned in the second direction Y;

step eight, two clamping jaws in the clamping jaw assembly move on the centering beam 533 along the second direction Y towards the second cutting station until the two clamping jaws respectively reach positions capable of clamping two side skins of the crystal bar;

step nine, after the two clamping jaws clamp the two side skins respectively, the middle beam 533 moves on the truss main body along the first direction X towards a direction away from the head assembly 43 so as to enable the side skins to slide and separate from the crystal bars;

in step ten, the middle cross beam 533 continues to drive the clamping jaw assembly to move along the first direction X towards a direction away from the nose assembly 43, the edge skin is moved out of the nose assembly 43 through the opening 437 on the nose assembly 43, and then the edge skin is conveyed to the edge skin collecting device 6.

The cutting unit of the crystal bar cutting system and the crystal bar cutting system have the following advantages:
