Description

一种光伏太阳能硅片减薄处理装置A photovoltaic solar silicon wafer thinning processing device

技术领域technical field

本发明一种光伏太阳能硅片减薄处理装置,涉及一种对光伏太阳能硅片进行预减薄处理的装置,属于光伏设备领域。特别涉及一种通过两级行星轮盘,对硅片进行双面磨削预减薄的装置。The invention relates to a thinning processing device for photovoltaic solar silicon wafers, which relates to a device for pre-thinning photovoltaic solar silicon wafers and belongs to the field of photovoltaic equipment. It particularly relates to a device for double-sided grinding and pre-thinning of silicon wafers through two-stage planetary wheels.

背景技术Background technique

目前,硅片被广泛应用在光伏领域,而硅片在加工过程中,需要对硅片的厚度进行适当的减薄调整,其主要原因是薄片可以降低器件的导通电阻和压降,从而大幅度减少器件的导通损耗,并提升器件在散热等方面的性能,现有的硅片加工时先对硅片进行切割,然后进行减薄,而硅片减薄方式包括研磨、化学机械抛光、干式抛光等,然而此类的减薄都是对硅片进行小范围内的减薄处理,精度要求较高,而切割后的硅片尺寸差值较大,直接进行上述方式进行减薄,费时费力,且对设备损失加大,且在减薄时,由于减薄磨削行程大,在磨削过程中会出现硅片内部应力释放导致开裂的问题,所以有必要在切割后以及精减薄之间增加预减薄的工作,以解决硅片减薄效率低、破碎率高的问题,同时现有的在磨削过程中,只能单独对硅片一面进行磨削,然后再更换另一面,这种方法不仅费时费力,降低了加工的效率,并且在对硅片进行翻转时需要配合真空吸盘,然而真空吸盘在翻转时会和硅片表面接触,对硅片表面造成损害,不利于硅片的后序加工。At present, silicon wafers are widely used in the field of photovoltaics, and during the processing of silicon wafers, the thickness of silicon wafers needs to be properly thinned and adjusted. The main reason is that thin wafers can reduce the on-resistance and voltage drop of devices, thereby greatly The conduction loss of the device can be greatly reduced, and the performance of the device in terms of heat dissipation can be improved. When the existing silicon wafer is processed, the silicon wafer is first cut and then thinned. The silicon wafer thinning method includes grinding, chemical mechanical polishing, Dry polishing, etc. However, this kind of thinning is to thin the silicon wafer in a small range, which requires high precision, and the size difference of the cut silicon wafer is relatively large. The above method is directly used for thinning. It is time-consuming and labor-intensive, and increases the loss of equipment, and when thinning, due to the large grinding stroke for thinning, the problem of cracking due to internal stress release of the silicon wafer will occur during the grinding process, so it is necessary to Add pre-thinning work between thinning to solve the problem of low thinning efficiency and high breakage rate of silicon wafers. At the same time, in the existing grinding process, only one side of the silicon wafer can be ground separately, and then the other side is replaced. On the one hand, this method is not only time-consuming and laborious, but also reduces the processing efficiency, and needs to cooperate with the vacuum chuck when turning the silicon wafer. Subsequent processing of silicon wafers.

If the rubber ring is made of metal materials, it is easy to cause damage to the side of the silicon wafer during the grinding process, which will affect the later processing and use. If the rubber ring is made of a ceramic material, then the fixing stability of the silicon chip is relatively poor. During the grinding process, the silicon chip is prone to shaking, which affects the progress of the grinding work. The design of a bump can increase the friction between the silicon chip and the rubber ring, further improve the stability of the silicon chip, prevent the silicon chip from shaking during the grinding process, and affect the grinding effect. The installation groove is built with rubber The design of the pad can better fix the grinding bar and reduce the vibration generated during the grinding process. The middle height of the grinding head is higher than the design on both sides, which can carry out progressive grinding on the silicon wafer. Grinding, the design of the wide inlet and narrow outlet of the chip removal groove is convenient for the discharge of silicon chips, and the design of the grinding flannelette made of ostrich fluff can not generate static electricity during the grinding process, preventing the grinding flannelette It absorbs the hard particles in the dust, scratches the silicon wafer during the grinding process, and achieves the purpose of pre-thinning the double-sided grinding of the silicon wafer through the two-stage planetary wheel.

When in use, before the silicon chip is refined and thinned, the silicon chip is first placed in the rubber ring (4), and the two grinding cutter heads ( 3) Grinding liquid is dripped into the grinding flannelette (9) on the top, connect the connecting shaft (18) with the external power device, and adjust the height of the distance-limiting pole (10) through the distance-limiting hole (11), thereby adjusting The thickness of the silicon wafer is ground, the external power rotation drives the connecting shaft (18) to rotate, and the connecting shaft (18) drives the first central gear (2) and the second central gear (7) to rotate respectively, and the first central gear (2) Drive the four planetary gears on the primary planetary carrier assembly (17) to rotate, and the four planetary gears on the primary planetary carrier assembly (17) respectively drive the first ring gear (16) to rotate, and the first ring gear (16 ) drives the lower grinding cutter head (3) to rotate, and the lower grinding cutter head (3) drives the grinding head (23) in the mounting groove (13) on the upper surface to rotate, thereby The surface is ground, the second sun gear (7) drives the four planetary gears on the secondary planetary carrier assembly (6) to rotate, and the four planetary gears on the secondary planetary carrier assembly (6) drive the second gear The ring (8) rotates, the second ring gear (8) drives the upper grinding cutter head (3) to rotate, and the upper grinding cutter head (3) drives the grinding knife in the mounting groove (13) on the lower surface The head (23) rotates to grind the upper surface of the silicon wafer, so as to grind the upper and lower sides of the silicon wafer at the same time. Part of the ground silicon chips will be absorbed by the grinding flannelette (9), and some will fall into the In the chip removal groove (22), as the silicon chips in the chip removal groove (22) continue to increase, they finally fall into the chip receiving tray (1), and the upper surface of the grinding table (12) is provided with a liquid guide groove The design facilitates the flow of grinding fluid on the grinding table (12) during the grinding process to assist the grinding work. The density of the liquid guide groove at the center of the grinding table (12) is greater than that at the edge The design makes it easier for the grinding fluid to be better retained on the grinding table (12) to further improve the grinding effect. The diameter of the rubber ring (4) gradually increases from the middle to both sides, which is convenient for placing silicon wafers. It is also convenient for the grinding head (23) to grind the silicon wafer, further improving the grinding effect. The design of the rubber ring (4) is the most suitable design for this program after many tests , if the rubber ring (4) is made of metal material, it is easy to cause damage to the side of the silicon wafer during the grinding process, which will affect the later processing and use; if the rubber ring (4) is made of ceramic material, it will damage the silicon wafer The fixation stability of the rubber ring (4) is relatively poor. During the grinding process, the silicon wafer is prone to shaking, which affects the progress of the grinding work. The inner wall of the rubber ring (4) is designed with multiple bumps evenly, which can increase the The friction between the silicon wafer and the rubber ring (4) further improves the stability of the silicon wafer, preventing the silicon wafer from shaking during the grinding process and affecting the grinding effect.
