Description

Technical Field

[0001] The invention relates to a structural design for smashing a quartz crucible, and in particular to a mechanical structure device and a method for smashing a quartz crucible. Background Art

[0002] A single crystal furnace is a device that uses a graphite heater to melt polycrystalline materials such as polysilicon in an inert gas (mainly nitrogen and helium) environment and grows single crystals without dislocation using the Czochralski method. Currently, single crystal furnaces use the RCZ multiple Czochralski technology to pull multiple crystal rods through multiple feedings.

[0003] In a CZ single crystal furnace, the thermal field is the core component of single crystal growth. Usually, the correct use of the thermal field can effectively improve the crystallization of the single crystal furnace and reduce production costs. After the single crystal furnace is finished pulling crystals, in order to improve the production efficiency of the single crystal furnace, the CZ single crystal furnace should be opened and the thermal field of the CZ single crystal furnace should be cleaned after the furnace is shut down for 6-8 hours.

[0004] At present, when dismantling the quartz crucible in the hot field of the single crystal furnace, the quartz crucible is mostly smashed directly with an iron rod and an axe. Its characteristics are: simple, trouble-free, convenient, and simple tools are used to smash the quartz crucible anywhere. Its disadvantages are: when smashing the quartz crucible, if the manual force is too large, the iron rod is easy to break or penetrate the crucible side outside the quartz crucible, making the crucible side unusable, thereby reducing the service life and increasing production costs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a mechanical structure device and method for conveniently smashing a quartz crucible. The device has a compact structure and is easy to use. While conveniently smashing the quartz crucible, it improves the work efficiency of workers and reduces the labor intensity of workers. At the same time, it also avoids smashing or penetrating the crucible side, thereby increasing the service life of the crucible rod and reducing costs.

[0006] In order to solve the above technical problems, the present invention provides a mechanical structure device for conveniently smashing a quartz crucible, comprising a knocking rod, a connecting sleeve, a base, a knocking head and at least three connecting rod mechanisms, the knocking rod is vertically arranged, the knocking rod is provided with a connecting sleeve, the knocking rod is also provided with a spring, the spring is located below the connecting sleeve, the knocking head is arranged on the connecting mechanism, at least three connecting rod mechanisms are evenly distributed around the knocking rod, one end of each connecting rod mechanism is connected to the connecting sleeve, and the other end is connected to the base, the middle part of the base is provided with a through hole penetrating the base, the knocking rod is arranged on the base, one end of the knocking rod provided with a spring extends out of the spring and is arranged in the through hole, the knocking rod moves up and down in the through hole of the base through the spring under the action of external force, and drives the connecting rod mechanism to smash and break the quartz crucible through the knocking head.

[0007] The technical solution further defined in the present invention is:

[0008] Furthermore, in the aforementioned mechanical structure device for conveniently smashing the quartz crucible, the connecting rod mechanism includes a first connecting rod, a second connecting rod, a support rod and a hammer rod, the middle part of the hammer rod protrudes outward to form a first mounting connecting piece, one end of the hammer rod is provided with a striking head, one end of the first connecting rod is connected to the connecting sleeve through the second mounting connecting piece, the other end of the first connecting rod is hinged to an end of the hammer rod away from the striking head, one end of the support rod is arranged on the outer wall of the base, the other end of the support rod is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the first mounting connecting piece on the hammer rod.

[0009] Preferably, the first connecting rod is hinged to the second mounting connecting piece.

[0010] In the aforementioned mechanical structure device for conveniently smashing a quartz crucible, the counterclockwise angle formed between the support rod and the base is an acute angle.

[0011] In the aforementioned mechanical structure device for smashing a quartz crucible, the base includes a base body and a bottom plate, one end of the base body extends outward to form a circular bottom plate, and the through hole penetrates the base body and the bottom plate.

[0012] Technical effect: the circular chassis can well support the operation of the upper components and also play the role of fixing the crucible.

[0013] In the aforementioned mechanical structure device for conveniently smashing a quartz crucible, the outer wall of the bottom plate has an inclined surface in the circumferential direction, and the inclined surface matches the inclined surface of the outer crucible side of the quartz crucible to fix the crucible side.

[0014] Technical effect: there is a slope in the circumferential direction of the chassis, which fits with the slope of the crucible side, so that it can better fix the crucible side.

[0015] In the aforementioned mechanical structure device for conveniently smashing a quartz crucible, the outer diameter of the through hole on the base is larger than the outer diameter of the knocking rod and smaller than the inner diameter of the spring.

[0016] The technical effect ensures that the striking rod can move up and down in the through hole of the base, driving the connecting rod mechanism to smash the crucible through the striking head to complete the work.

[0017] In the aforementioned mechanical structure device for conveniently smashing a quartz crucible, the side of the striking head contacting the crucible is the striking surface, and the striking surface is an arc surface structure.

[0018] Technical effect: The present invention strictly limits the shape of the striking surface. If the contact surface of the striking surface is too large, it is not easy to break the crucible. If the contact surface is too small, it is easy to pierce the side of the crucible. When the striking head contacts the crucible, the corners contact the crucible first, which is easy to damage the striking head. After adopting the arc surface, the force is evenly distributed, which protects the striking head and can better smash the crucible.

[0019] In the aforementioned mechanical structure device for conveniently smashing the quartz crucible, the device is made of stainless steel.

[0020] The present invention also designs a method for conveniently smashing a quartz crucible, which uses the above-mentioned mechanical structure device for conveniently smashing a quartz crucible to smash the crucible, and specifically includes the following steps:

[0021] : Smash the bottom of the cooled quartz crucible, and place the quartz crucible with the smashed bottom and the crucible side on the mechanical device through the hole smashed at the bottom, so that the bottom inclined surface of the crucible side fits with the inclined surface of the chassis in the mechanical device, and the base fixes the crucible side;

[0022] : Use an axe to vertically strike the vertically set striking rod. After the striking rod is subjected to force, the spring is compressed and moves downward. The force is evenly divided into multiple directions through the connecting rod mechanism, specifically:

[0023] The connecting sleeve and the base drive the hammer rod through the first connecting rod, the support rod and the second connecting rod, so that the striking surface of the striking head on the hammer rod hits the inner wall of the quartz crucible, and the striking heads in the multiple connecting rod mechanisms hit the inner wall of the quartz crucible at the same time;

[0024] : When the force on the knocking rod is removed, the spring rebounds and restores the knocking rod to the initial state to prepare for the second force operation. At this time, the connecting sleeve and the base drive the hammer rod to retract through the first connecting rod and the second connecting rod respectively, so that the knocking head on the hammer rod leaves the inner wall of the quartz crucible;

[0025] : Use this reciprocating motion to complete the work of smashing the crucible.

[0026] In the aforementioned method for conveniently smashing a quartz crucible, when the spring is in the original state of the mechanical structure device, a gap of 5-10 mm is left between the striking head on the connecting rod mechanism and the inner wall of the quartz crucible.

[0027] The technical effect is that the crucible with the bottom smashed open and its crucible side can be smoothly placed on the mechanical mechanism device to complete the subsequent smashing of the crucible and ensure the normal operation of the work.

[0028] The beneficial effects of the present invention are:

[0029] The present invention provides a through hole in the middle of the chassis, which ensures that the crucible side and the quartz crucible can be fixed, and at the same time, the support rod of the connecting rod mechanism reciprocates in the through hole, playing a role of fixing and guiding.

[0030] The present invention can determine how many connecting rod mechanisms to set up according to actual conditions. The connecting rod mechanisms divide the force into multiple directions. The knocking rod is moved downward by external force, and the spring structure is used in the middle to restore the initial state to complete the upward movement. The base plays the role of fixing the crucible side and supporting the movement of the upper parts.

[0031] The structure of the present invention can disperse the force to multiple positions under the action of vertical downward force, thereby reducing the effect of force concentration at a certain position and destroying the crucible side when the pot is smashed, and further protecting the crucible side while breaking the quartz crucible.

[0032] The structure of the present invention can buffer the downward force when the connecting rod mechanism is under force, and can automatically restore the connecting rod mechanism to an initial state when the external force is cancelled, so as to prepare for the next force movement. The structure is easy to use and does not require manual operation to break the crucible bit by bit, thereby improving work efficiency and protecting the crucible side.

[0033] Compared with the prior art, the present invention changes the previous way of smashing the quartz crucible and designs a set of mechanical tooling for mechanically smashing the quartz crucible, which effectively prevents the crucible side from being broken or penetrated while smashing the quartz crucible. While protecting the crucible side intact, it is convenient for workers to operate and reduce the labor intensity of workers, thereby increasing the reuse rate of the crucible side, increasing the service life of the crucible rod, reducing costs, and creating benefits.
