[0002] Currently, mainly in the photovoltaic industry, and in addition, in industries such as semiconductor and single crystal manufacturing, companies using single crystal furnaces to produce products all adopt artificial driving of special crystal picking equipment. Below the crystal picking equipment, the method of manually assisting in stabilizing the product (crystal bar) is used to complete the clamping work after the product is produced.

[0003] 1) During the on-site crystal picking operation process, the lateral movement of the auxiliary chamber causes the crystal bar to shake more, increasing the risk of dropping;

[0004] 2) After the auxiliary chamber rotates to the side limit and continues to operate, the protective crystal holder needs to be lifted. At this time, the area below the auxiliary chamber is in an unprotected state;

[0005] 3) To stabilize the product (crystal bar), workers need to use a tooling to contact the end of the crystal bar manually. When stabilizing the crystal bar, the worker is below the auxiliary chamber (product), as Figure 1 shown;

[0006] In the above operation process, the safety risk is very high. Personnel are below the unprotected auxiliary chamber. Once the product (crystal bar) drops due to broken fine crystals, graphite chucks, molybdenum weights, or steel wire ropes, or multiple crystal bars break when picking up multiple crystal bars, the consequences will be unimaginable.

The embodiments of the present invention will be described below according to the overall structure of the present invention.

[0033] Please refer to Figures 2 - 4 , the present invention provides a technical solution: a crystal bar stability assistance device during the process of taking a crystal bar, including:

[0034] A support plate 101, and a spring placement groove 102 is arranged at the top of the support plate 101;

[0035] Support arm 103, the support arm 103 is installed at the left and right ends of the support plate 101. A fixing block 104 extends from the front end of the support arm 103. Mounting holes 105 and sliding holes 106 are provided on the support arm 103, and the mounting hole 105 is located above the sliding hole 106;

[0036] Protective plate 107, first sliders 108 extend from the left and right ends of the protective plate 107, and the first sliders 108 are installed in the sliding holes 106; second sliders 109 extend from the front end of the protective plate 107, and the second sliders 109 are located between the fixing blocks 104;

[0037] Vibration damping spring 110, one end of the vibration damping spring 110 is installed in the spring placement groove 102, and the other end of the vibration damping spring 110 is installed at the bottom end of the protective plate 107;

[0038] First infrared detection member 111, the first infrared detection member 111 is installed in the sliding hole 106 and fixed at the top of the sliding hole 106;

[0039] Second infrared detection member 112, the second infrared detection member 112 is installed inside the fixing block 104.

[0040] This device changes the rod-taking step from a completely manual operation to 50% being automatically completed by the equipment. The design of the vibration damping spring 110 eliminates the adverse vibration effects of the crystal rod 300 during transportation. At the same time, the protective plate 107 plays a protective role for the crystal rod 300 in the semi-automatic state, avoiding the situation where the crystal rod 300 falls and injures the personnel 500, and improving the structural integrity rate of the crystal rod 300 during the transportation of the crystal rod 300.

[0041] Auxiliary chamber furnace cylinder 200, mounting grooves are provided on both sides of the outer wall of the auxiliary chamber furnace cylinder 200, and the distance from the mounting groove to the bottom of the auxiliary chamber furnace cylinder 200 is less than the distance from the mounting hole 105 to the protective plate 107.

[0042] Fixing member 113, the fixing member 113 passes through the mounting hole 105 and is movably connected in the mounting groove. The fixing member 113 can be a bolt or a rivet.

[0043] For example, using a bolt, in the preparation stage before normal single crystal pulling, the bolt of the crystal rod stability assisting device 100 is tightened to one side of the outer wall of the auxiliary chamber furnace cylinder 200. At this time, the single crystal furnace 600 is normally performing single crystal pulling work. Until after the single crystal pulling is completed, the bolt is loosened. At this time, the crystal rod stability assisting device 100 adheres to the outer wall of the single crystal furnace 600 downward due to gravity. When the auxiliary chamber furnace cylinder 200 is lifted, the crystal rod stability assisting device 100 rotates to the bottom of the auxiliary chamber furnace cylinder 200, thereby protecting the crystal rod 300 in the auxiliary chamber furnace cylinder 200.

[0044] In the original state of the damping spring 110, the protective plate 107 is not in contact with the first infrared detector 111, avoiding interference of the protective plate 107 with the detection function of the first infrared detector 111. It detects the descending position of the crystal bar 300 to confirm the descending state of the crystal bar 300.

[0045] The first infrared detector 111 includes a first infrared emitter and a first infrared receiver. The first infrared emitter and the first infrared receiver are respectively installed on the inner side of the support arm 103 and are arranged opposite to each other to ensure the normal operation and detection of the first infrared detector 111. At the same time, the first infrared detector 111 has the same model as the second infrared detector 112 and can adopt the existing technology, which will not be elaborated here.

[0046] The first infrared detector 111 and the second infrared detector 112 are connected to the control system. When the crystal bar 300 passes through the first infrared detector 111, the operation of the crystal bar 300 stops. When the second slider 109 passes through the second infrared detector 112 due to the descent of the crystal bar 300, the operation of the crystal bar 300 stops. At this time, on the one hand, the crystal bar 300 is pulled by the seed crystal, and the seed crystal is still in a stressed state. On the other hand, the crystal bar 300 is lifted by the crystal bar stable auxiliary device 100, further reducing the tensile stress intensity on the seed crystal. At the same time, it can also make the rotation and handling process of the crystal bar 300 safer and more stable before "taking the bar".

[0047] When the second slider 109 is located between the second infrared detectors 112, the second slider 109 can block the light beam emitted by the second infrared detectors 112, ensuring the normal operation of the second infrared detectors 112 and enabling timely response to the operation state of the crystal bar 300.

[0048] The protective plate 107 is a tetrafluoroethylene plate, i.e., polytetrafluoroethylene, which is heat-resistant and has a heat insulation and protection effect, avoiding the explosion of the crystal bar 300 when it contacts the metal.

[0049] Working principle: After the single crystal furnace 600 produces the crystal bar 300, on-site employees perform the operation of taking the crystal bar 300. When the crystal bar 300 in the single crystal furnace 600 is normally isolated in the secondary chamber furnace barrel 200, the secondary chamber furnace barrel 200 is lifted, and the crystal bar stable auxiliary device 100 rotates to directly below the secondary chamber furnace barrel 200. Then the secondary chamber furnace barrel 200 rotates and is moved to the side for limiting, preparing for the operation of taking the bar;

[0050] The control system enters the automatic bar-taking process step:

[0051] Phase 1. In this phase, the seed crystal pulls the crystal bar 300 to rapidly descend automatically at a certain speed. When it reaches the first infrared detector 111 at the lower end of the secondary chamber furnace barrel 200, it stops working. The crystal bar 300 hovers and stands still. On-site employees confirm that the crystal bar 300 is in place and click "Continue to take the bar" in the control system;

[0052] In the second stage, the ingot 300 continues to slowly descend at a low speed until it contacts the protective plate 107 inside the ingot stability assisting device 100. At this time, the damping spring 110 below the protective plate 107 starts to be stressed and increases, gradually slowing down the descending speed of the ingot 300. After descending a certain distance, the ingot 300 is detected by the second infrared detector 112 installed on the ingot stability assisting device 100, and the ingot 300 stops running and is in a static state.

[0053] In the third stage, after the ingot 300 has been static for 10 s, the control system alarms "Confirm that the ingot 300 is stable". After the on-site staff confirm, they click "Continue to pick up the ingot", and the ingot 300 is lifted by 200 mm. The protective plate 107 is lifted accordingly, and the operation step of automatically stabilizing the ingot 300 is completed. The on-site staff switch to manual operation on the system interface for the next operation.

[0054] It should be noted that when the ingot 300 descends to the lowest point, the seed crystal at the top of the ingot 300 is still under stress. Otherwise, there is a risk of fine crystal fracture and the ingot 300 falling.

[0055] This device fundamentally eliminates the safety risks to employees caused by the falling of the ingot during the ingot picking process in the industry, provides a range of protection for the ingot picking process, and further increases the structural stability and safety.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
