For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0061] In addition, in order to better illustrate the utility model, a large number of specific details are given in the specific embodiments below, and those skilled in the art should understand that the utility model can also be implemented without certain specific details. In some examples, the principles of slicer and the like well known to those skilled in the art are not described in detail in order to highlight the main idea of the utility model. The utility model will be described below with reference to all or part of the drawings. Figures 1 to 7

[0062] The slicer 100 usually includes a frame, the frame is formed with a cutting chamber 1, a cutting mechanism (the cutting mechanism in the drawing is removed) wound with a wire net is arranged in the cutting chamber, and a feed mechanism 2 can approach or move away from the upper surface of the cutting mechanism in the vertical direction. Exemplarily, the cutting mechanism capable of slicing the silicon rod (square rod) usually includes at least two cutting main rollers (such as two, three, etc., such as three in an inverted triangular distribution in this example). In general, the operation mode of the slicing operation is as follows: after the rod is fixed in the adhesive workshop (such as the silicon rod 200 to be sliced is fixed at the bottom of the crystal holder 201 to form a crystal rod by means of adhesive in the adhesive workshop), the crystal holder is fixed on the feed mechanism, and the wire net is reciprocated between the cutting main rollers of the cutting mechanism. By driving the silicon rod to approach the wire net (such as vertically downward) by the feed mechanism 2, the silicon rod 200 can be cut by the wire saw to slice the square rod. In general, the feeding and discharging device can be arranged on the front side or the rear side of the slicer, and the silicon rod 200 carried on the crystal holder 201 can reach the position corresponding to the cutting operation in the cutting chamber by the corresponding feeding and discharging device in a manual or automatic conveying manner. As in this example, the feeding and discharging device 3 is arranged on the rear side of the slicer.​

[0063] In a possible implementation, the loading and unloading device 3 mainly comprises a transfer trolley 31, a conveying robot (such as a robot clamp, etc.) 32, and a passage assembly 33, wherein the silicon rod bonded to the crystal holder can be carried to the transfer trolley 31, the conveying robot 32 can grab the transfer trolley 31 and provide forward driving force for the transfer trolley, under the action of the forward driving force, the transfer trolley 31 can be docked with the passage assembly 33 and the silicon rod 200 carried on the transfer trolley 31 can be delivered to a position corresponding to the cutting operation in the cutting chamber 1 through the movement of the transfer trolley 31 along the passage assembly 33.

[0064] In a possible implementation, the loading and unloading device 3 comprises a docking assembly 34, the docking assembly 34 comprises a first docking assembly 341 and a second docking assembly 342, and the conveying robot 32 fixedly arranged in the installation space can be connected with the transfer trolley 31 through the first docking assembly 341 or the second docking assembly 342 and provide forward driving force for the transfer trolley to approach the cutting chamber.

[0065] In a possible implementation, the first docking assembly 341 comprises a first cylinder 3411 as a first lifting mechanism (in addition to the cylinder, the driving part can also be other forms of power cylinder such as a hydraulic cylinder, an electric cylinder, etc. or other forms of linear module that can realize lifting movement) and a first driving part, the first driving part comprises a first driving motor 3412 as a first driving part and a rack and pinion mechanism as a first transmission mechanism (in addition to the rack and pinion mechanism, the transmission mechanism can also be a lead screw nut mechanism, etc.), wherein the gear 3413 (first transmission part) of the rack and pinion mechanism is arranged on the conveying robot, and the rack 3414 (second transmission part) of the rack and pinion mechanism is arranged on the transfer trolley. By driving the first transmission part (and the driving part) in the driving part to move towards the second transmission part through the lifting mechanism, the docking between the first transmission part and the second transmission part can be realized, which, in this example, is manifested as the gear and the rack of the rack and pinion mechanism being in meshing state. On this basis, by moving the first driving part, the linear movement of the transfer trolley approaching the cutting chamber can be realized.

[0066] In a possible implementation, the second docking assembly 342 comprises a second cylinder 3421 as a second lifting mechanism, a third cylinder 3422 as a second driving part, and a set of docking features capable of docking with each other (the first docking feature provided on the transport robot and the second docking feature provided on the transfer trolley (provided at the tail or close to the tail in the forward direction), in this example, the second lifting mechanism and the second driving part are provided on the transport robot, and the first docking feature is an extension end 3423 provided on the power output end of the second driving part, in this example, the structure of the extension end is that a transverse portion is provided on the power output end of the third cylinder, and a plug or the like vertical extension end is provided at the end of the transverse portion away from the third cylinder, and the second docking feature is a docking hole (push hole) 3424 provided at the tail of the transfer trolley, wherein the crystal holder 201 has a slot 2011 allowing the extension end to slide freely. The docking process of the first docking feature and the second docking feature is that the second cylinder extends downward, the combination of the third cylinder and the plug is lowered as a whole, and thus the plug is inserted into the push hole. Based on this, the third cylinder can be extended forward to push the transfer trolley to move forward.

[0067] It can be seen that the second lifting mechanism can not only ensure that the first docking feature and the second docking feature can reliably dock, but also avoid interference between the extension end and the transfer trolley by moving the extension end upward when the second docking assembly is in a non-working state. Similar to the first lifting mechanism, the second lifting mechanism can also be a hydraulic cylinder, an electric cylinder, other forms of power cylinder, a linear module capable of vertical lifting motion, etc.

[0068] Obviously, under the premise of realizing interference-free docking, those skilled in the art can flexibly adjust the structure of the first / second docking feature according to actual needs, such as the combination of hooks and holes, the combination of buckles and holes, the combination of clamping jaws and clamping plates, etc. In the state that the first docking feature and the second docking feature are docked, the second driving part can drive the transfer trolley to move forward to approach the cutting chamber. If the mating position of the first / second docking feature is located at the side of the transfer trolley (such as transverse insertion), the second lifting mechanism can be omitted.

[0069] In this example, the second driving part is a third cylinder, and obviously, those skilled in the art can flexibly select the structure of the second driving part according to actual needs, such as a hydraulic cylinder, an electric cylinder, other forms of power cylinder, a linear module capable of horizontal linear motion, etc.

[0070] Based on this, the movement of the transfer trolley carrying the silicon rod on the channel assembly includes two stages with sequence, in the first stage, the driving connection between the conveying robot and the transfer trolley is realized through the first docking assembly. In the second stage, the driving connection between the conveying robot and the transfer trolley is realized through the second docking assembly. Through the cooperation of the driving connection of the two stages, the silicon rod carried on the transfer trolley can be delivered to the position corresponding to the cutting operation in the cutting chamber.

[0071] In the first stage in the example, the first cylinder pushes the gear downward, so that the gear and the rack are engaged, based on which the driving motor rotates, which can drive the rack to advance and thus drive the transfer trolley to advance. However, due to the limited length of the rack, the feeding path realized based on the engagement between the gear and the rack is certain. In the utility model, after the engagement between the gear and the rack is disengaged, the protruding end on the conveying robot (in the first stage, the protruding end can freely slide in the groove on the upper surface of the crystal holder) is inserted into the jack on the transfer trolley, and the protruding end is pushed forward by the second cylinder, thereby driving the transfer trolley carrying the crystal rod to continue to push forward until the transfer trolley is docked with the channel assembly.

[0072] Based on the docking of the transfer trolley and the channel assembly, the transfer trolley carrying the crystal rod is delivered to the position corresponding to the cutting operation in the cutting chamber through the third driving part arranged on the channel assembly. In the example, the third driving part includes a second driving motor (such as a servo motor, etc.) 331, a synchronous belt and a screw nut mechanism, etc. Obviously, those skilled in the art can flexibly adjust the constituting form of the third driving part according to actual needs, such as a power cylinder or other arbitrary reasonable linear module, etc.

[0073] In a possible implementation, the transfer trolley is docked with the channel assembly in a suspended manner. Exemplarily, a roller is arranged on the top of the transfer trolley, and correspondingly, a track allowing the roller to roll is arranged on the lower side of the top of the channel assembly. The channel assembly is provided with a connection structure 332 (such as a suspended rail assembly, a plate-shaped structure, a structure with a roller group, etc.) at a position close to the slicing machine, so as to ensure the reliable docking of the channel assembly with the cutting chamber of the slicing machine, and thus enable the transfer trolley to smoothly enter the cutting chamber of the slicing machine via the channel assembly.

[0074] As can be seen, in the preferred embodiment of the utility model, through the cooperation of the first docking assembly and the second docking assembly, the conveying robot can establish driving transmission connection with the transfer trolley in a staged form through different driving transmission modes. On this basis, through the combination of the two driving transmission connections, the transfer trolley can be reliably delivered to the channel assembly. Then, through the driving transmission connection established with the channel assembly, the workpiece can be reliably delivered to the position corresponding to the cutting operation in the cutting chamber.

[0075] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the drawings, but it will be readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the relevant technical features without deviating from the principles of the present application, and the technical solutions after these changes or replacements will all fall within the scope of protection of the present application.
