Embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Referring to FIGS. 1 to 4, the present utility model provides a single crystal crucible bed charge remover comprising:

the frame 100 is fixedly arranged on the ground, and is internally provided with a carrying platform 110;

a transfer car 200 for transporting the crucible-side assembly with the backing material to one side of the frame 100;

the turnover mechanism 300 is rotatably connected to one side of the top surface of the carrier 110 and is used for clamping the crucible and the table assembly on the transfer trolley 200, turning over for 180 degrees and then placing the crucible and the table assembly on the carrier 110; a kind of electronic device with high-pressure air-conditioning system

The top punching mechanism 400 is connected to the top of the frame 100 in a lifting manner and located right above the carrier 110, and is used for ejecting the backing material in the crucible and its assembly.

During specific work, the crucible assembly with the bottom material is firstly lifted out of the single crystal furnace and placed on the transfer trolley 200, then the transfer trolley 200 is pushed to one side of the frame 100 and is stopped beside the turnover mechanism 300, then the turnover mechanism 300 is started to clamp the crucible assembly with the bottom material and hold the crucible assembly with the bottom material up and turn over 180 degrees around the horizontal axis, so that the crucible assembly with the bottom material is reversely buckled on the carrier 110 and kept in a clamping state, at the moment, the top-punching mechanism 400 descends to be aligned with the upward bottom shaft hole of the crucible assembly to impact the bottom material so as to enable the bottom material to be quickly separated from the crucible assembly, and thus the knockout operation of the crucible material can be conveniently and smoothly completed, and silicon material can be blocked and can not splash everywhere due to the reversely buckling of the crucible assembly; when the residual backing material in the crucible assembly is removed, the ram 400 is raised and the turnover mechanism 300 is reversed by 180 to reset and release the crucible assembly for return to the transfer car 200. That is, after the crucible and the back-off is performed by the turnover mechanism 300 and the crucible and the back-off is performed by turning over 180 degrees, the impact type operation is performed on the residual bottom materials in the crucible and the back-off mechanism 400 to replace manual knockout operation of the crucible bottom materials, so that the working environment of staff is improved to avoid scalding, the time of waiting for cooling the crucible bottom materials at high temperature is saved to improve the working efficiency and reduce the working strength of staff, and meanwhile, the back-off crucible and the back-off mechanism can prevent the silicon materials from splashing everywhere, so that the pollution to the operation environment is reduced.

In order to ensure that the crucible-side assembly on the transfer car (200) can be directly clamped (i.e. just centered) by the tilting mechanism (300), a pair of first grooves (101) are formed in the ground, the walking directions of the universal casters of the transfer car (200) are standardized, and a pit (102) is formed in the corresponding position of each first groove (101), and is used for positioning the universal casters of the transfer car (200) and limiting free rolling of the universal casters. Meanwhile, in order to prevent the transfer car 200 from running or shaking during the clamping process of the crucible-side assembly, magnets (not shown in the figure) are installed in the pits 102, and the magnets can absorb the universal casters of the transfer car 200 to limit the free rotation of the universal casters. After the crucible assembly after finishing the bottom material removing operation returns to the transfer cart 200, the worker applies an external force to the transfer cart 200, and after overcoming the suction force of the magnet, can move away the transfer cart 200 to transport the crucible assembly to other places (such as cutting the crucible).

Referring to fig. 3 and 4, the tilting mechanism 300 includes a motor 310, a bracket 320, and a pair of arms 330; the motor 310 is arranged on the top surface of the carrier 110, and the bracket 320 is fixedly connected with the output end of the motor 310; one arm 330 is fixedly connected with the bracket 320, and the other arm 330 is slidably connected with the bracket 320 by driving of the first hydraulic cylinder 340. That is, the size between the pair of arms 330 is changed by the driving of the first hydraulic cylinder 340 so as to clamp and hold the crucible and the upper assembly with the backing material, and then the overturning around the horizontal axis is achieved by the driving of the motor 310.

In order to improve stability of the crucible-side assembly during overturning and to avoid scratching the outer side wall thereof, the arm 330 is of an arc-shaped bent structure, and a rubber pad is arranged on one surface of the arm, which contacts the outer side wall of the crucible-side assembly. That is, the arc-shaped bent arm 330 has a large contact area with the outer side wall of the crucible-side assembly, and the rubber pad can increase the friction force therebetween.

The punching mechanism 400 comprises a cross beam 410 and a punch 420, wherein the cross beam 410 is in sliding connection with a pair of vertical guide rails arranged on the frame 100 through the driving of a second hydraulic cylinder 430, and the punch 420 is hoisted at the middle of the lower end of the cross beam 410 and is positioned right above the carrier 110. That is, the ram 420 moves up and down following the sliding of the beam 410 on the vertical rail by the driving of the second hydraulic cylinder 430, thereby performing impact work on the bed charge remaining in the crucible and the plate assembly.

Referring to fig. 2, a vibrator 440 is installed at the middle of the upper end of the cross member 410, and the vibrator 440 is opposite to the punch 420. That is, when the vibrator 440 is started, the punch 420 can generate a high-frequency impact force to accelerate the falling of the crucible backing material, thereby further improving the working efficiency.

The above-mentioned single-crystal crucible bed charge remover further comprises an electric cabinet 500 installed on the front floor of the frame 100, and the electric cabinet 500 is provided with four pairs of control buttons 510 for controlling the actions of the motor 310, the first hydraulic cylinder 340, the second hydraulic cylinder 430 and the vibrator 440, respectively.

The middle part of the carrying platform 110 is provided with a discharging cone hopper 111, a receiving trolley 600 is arranged on the ground below the discharging cone hopper 111, the receiving trolley 600 is provided with a material box 610, the upper part of the material box 610 is of a dome-shaped space structure with a circular feeding hole 611, and the diameter of the circular feeding hole 611 is 1-2 cm larger than that of the discharging hole of the discharging cone hopper 111. In this way, the purged crucible bed charge can be timely dropped into the feed box 610 from the feed cone 111, and at the same time, silicon material can be further prevented from splashing around.

In order to facilitate the centering of the circular feeding hole 611 and the discharging hole of the discharging cone bucket 111, a pair of second grooves 103 are formed in the ground and used for standardizing the traveling direction of universal casters of the material receiving vehicle 600.

The above embodiments are only preferred embodiments of the present utility model, and are not limiting to the technical solutions of the present utility model, and any technical solution that can be implemented on the basis of the above embodiments without inventive effort should be considered as falling within the scope of protection of the patent claims of the present utility model.
