- the solar cell welding equipment provided in this embodiment integrates a lifting device; the structure and operation process of the lifting device are mainly described below, and the structure of the solar cell welding device is also described.
- the lifting device provided in this embodiment includes a lifting driving mechanism 12, a suction cup 13, and a hinge shaft 14.
- the suction cup 13 is suspended on the lifting member of the lifting driving mechanism 12; the suction cup 13 and the lifting member are hinged through a hinge shaft 14.

- the suction cup 13 Because the suction cup 13 is suspended from the lower side of the lifting member through the hinge shaft 14, the suction cup 13 can rotate relative to the lifting member when a force other than its own gravity acts. Using this mechanism, combined with the reasonable position setting in the specific application, the photovoltaic chip 01 can be lifted up in rotation. The following specifically analyzes how the lift-up device realizes the rotary lift-up of the photovoltaic chip with reference to FIG. 3.
- the lifting drive mechanism 12 drives the suction cup 13 to move downward until the working surface (that is, the suction surface) of the suction cup 13 fits the surface of the photovoltaic chip 01 (it should be noted that the suction cup 13 attracts The PV chip 01 is close to the surface on the outer peripheral side of the lifting device, and the adsorption position is outside the center of gravity of the PV chip 01); Subsequently, the suction cup 13 works and sucks the PV chip 01 by the negative pressure; at the same time, the lifting driving mechanism 12 is reversed The movement causes the suction cup 13 to move upward.
- the photovoltaic chip 01 and the suction cup 13 are integrated; because of the gravity of the photovoltaic chip 01 itself, and the center of gravity of the photovoltaic chip 01 and the suction position of the suction cup 13 do not coincide, the photovoltaic chip 01 chip will merge It cannot be moved up and down horizontally, but there will be a tendency to deflect; and because the suction cup 13 and the lifting member are connected through the hinge shaft 14, the suction cup 13 can maintain the fit with the photovoltaic chip 01 and rotate relative to the hinge shaft 14. At the same time, the photovoltaic chip 01 will rotate around point O and will not leave the substrate 02 of the solar photovoltaic module; that is, the photovoltaic chip is lifted up in a rotating manner.

- the suction cup 13 adsorbs the photovoltaic chip 01, the gravity center of the suction cup 13 and the photovoltaic chip 01 and the gravity center of the suction cup 13 are not offset by a large distance due to the weight ratio of the suction cup 13 is large.

- the main purpose of setting the bracket 15 is to deflect the suction cup 13 to a certain extent; but the deflection direction of the suction cup 13 is set as follows: when the suction cup 13 is in a natural suspension state, its suction surface It should be oriented obliquely downward toward the outer peripheral side of the frame 11, that is, in the state shown in FIG. 4.

下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。
如图4-图6所示，本实施例提供的太阳能电池焊接设备集成掀起装置；以下主要说明掀起装置的结构和动作过程，并附带说明太阳能电池焊接设备的结构。
如图2、图3和图4所示，本实施例提供的掀起装置包括升降驱动机构12、吸盘13和铰接轴14。
吸盘13吊设在升降驱动机构12的升降部件上；吸盘13与升降部件通过铰接轴14铰接。
在本申请一些实施例中，掀起装置还包括：机架11。
机架11为承载其他组件、实现其他部件协同工作的基础。实际应用中，机架11可以是结构较为简单的支撑部件，例如可以是立杆，并不限于本申请附图所述的结构和形态。
升降驱动机构12安装在机架11上，包括基座121、驱动部件和升降部件；基座121安装在机架11上，驱动部件安装在基座121上，升降部件与驱动部件的工作端连接，可以随驱动部件的动作而上下往复移动。吸盘13 吊设地安装在升降部件的下侧，通过铰接轴14与升降部件连接。
因为吸盘13通过铰接轴14吊设在升降部件的下侧，所以在有除自身重力以外的力量作用时，吸盘13可以相对升降部件转动。利用这一机构，结合具体应用中的合理位置设置，可以使光伏芯片01以转动地掀起。以下结合图3具体分析掀起装置如何实现光伏芯片的转动式掀起。
在呈现图3所示的状态前，升降驱动机构12带动吸盘13向下移动，直至吸盘13的工作面(也就是吸附面)贴合光伏芯片01的表面(应当注意，此时，吸盘13吸附的是光伏芯片01靠近掀起装置外周侧的表面，并且吸附位置位于光伏芯片01重心的外侧)；随后，吸盘13工作、依靠负压作用吸附光伏芯片01；与此同时，升降驱动机构12反向运动，使得吸盘13向上移动。
由于吸盘13的负压吸附作用，光伏芯片01和吸盘13为一体状态；因为光伏芯片01本身的重力作用，并且光伏芯片01的重心与吸盘13吸附位置并不重合，所以光伏芯片01芯片会并不能水平地上下移动，而是会有发生偏转的趋势；而正是因为吸盘13和升降部件通过铰接轴14连接，所以吸盘13可以保持与光伏芯片01的贴合，相对铰接轴14转动。同时光伏芯片01会绕O点发生转动，不会离开太阳能光伏组件的基板02；也就是光伏芯片被转动式地掀起。
当光伏芯片01被吸盘13提升至一定的高度，可以在光伏芯片01和基板02之间放入隔离板。放入隔离板后，升降驱动机构12带动吸盘再次向下移动，使光伏芯片贴合基板后；焊接装置焊接连接引流带和汇流带。
焊接装置完成焊接后，升降驱动机构12带动吸盘再次向上移动，随后抽离隔离板，升降驱动机构12带动吸盘下落，使光伏芯片再次贴合基板。
在前述动作过程中，因为光伏芯片01一侧边始终接触太阳能电池组件的基板02，而不是完全脱离基板02，所以连接前述光伏芯片01和相邻光伏芯片01的引流带不会受到强牵拉力作用，也就减少了因为牵拉力作用造成引流带脱焊、断裂的概率。
实际应用中的吸盘13多采用金属材料制成，其本身的重量较大，而光伏芯片01多为薄板状，重量较轻。在前述动作过程中，吸盘13吸附光伏 芯片01后，因为自身重量比重较大，所以吸盘13和光伏芯片01整体的重心和吸盘13本身的重心偏移距离并不大，造成实际应用中吸盘13转动角度较小。而在前述动作高速进行时，光伏芯片01被整体抬起的概率仍然较大。
为减小光伏芯片01被整体抬起的概率，在本申请的一些实施例中，掀起装置还包括支架15。请继续参见附图，具体参见附图2和附图6，支架15设置在吸盘13和升降部件之间；具体的，支架15包括吊装臂151和安装臂152，吊装臂151和安装臂152连接为一体，二者的延伸方向形成一夹角。吊装臂151通过铰接轴14与升降部件铰接连接，吸盘13固定安装在安装臂152上。
因为支架15的吊装臂151和安装臂152的延伸方向不同，二者之间具有夹角，所以在静置悬停状态下，为了使吸盘13的重心位于铰接轴14所在的竖直平面上，吸盘13必然带动支架15绕着铰接轴14旋转、并呈现倾斜状态；而当吸盘13位置下移、吸附平放的光伏芯片01时，吸盘13会处于摆正状态；当吸盘13上提时，吸盘13会在自身重力作用下摆动；如此，利用吸盘13自身的摆动,可以克服升降驱动机构12中升降部件的突然工作对光伏芯片01的冲击作用，继而避免光伏芯片01被整体抬起。
另外，设置前述的支架15，还可以避免在抬起光伏芯片01的瞬间，吸盘13脱离光伏芯片01，继而减小光伏芯片01跌落的概率。
应当注意，在本申请的一些实施例中，设置支架15的主要目的是使吸盘13发生一定的偏转；但是吸盘13的偏转方向设置为：，吸盘13处在自然悬吊状态时，其吸附面可应当斜向下地朝向机架11的外周侧，即处在如图4所示的状态；在本申请的一些实施例中，如果吸盘13处在自然悬吊状态时，吸附面斜向下朝向机架11的中心位置，不仅不能达到前述的效果，反而还会产生破坏性的效果。
在本申请的一些实施例中，也可以不设置前述支架15；即在自然悬吊状下，吸盘13的吸附面也可以垂直于竖直方向。
请继续参看图2和图4，本实施例提供的掀起装置中，升降驱动机构12包括基座121、第一驱动电机122、丝杠123、导轨124和滑块125。其 中基座121直接与机架11连接；第一驱动电机122固定安装在基座121上；丝杠123通过连轴器与第一驱动电机122的输出端连接，可以在第一驱动电机122的驱动力作用下转动；导轨124位于丝杠的侧部，平行于丝杠123的延伸方向设置；滑块125与丝杠123螺纹配合，并被导轨124限制转动方向。结合丝杠机构的工作原理可知，滑块125即是前文提及的升降部件。
本申请的一些实施例中，为避免升降驱动机构12与太阳能电池焊接设备中的其它部件发生位置冲突、留出安装其它工作设备的空间，滑块125上安装有一连接板，支架15实际与连接板铰接；但是应当注意，因为连接板本身与滑块125固定连接，所以其可以被认为是滑块125的一部分。
在本申请的一些实施例中，升降驱动机构12并不限于前述的结构，也可以是机械领域中采用的其它机构；例如机械领域采用的曲柄滑块机构、伸缩气缸机构或者伸缩油缸机构。
在实际生产中，太阳能电池焊接设备可能会适应不同尺寸大小的太阳能电池组、不同大小的光伏芯片01的组装；因此还具有在图2所示的左右方向移动吸盘13的需求。
为满足前一段提及的应用需求，在本申请的一些实施例中，掀起装置包括平移机构16；平移机构16安装在机架11上；而前述的升降驱动机构12设置在平移机构16的平移部件上。并且，平移部件的移动方向与前述铰接轴14之间的夹角大于0°。实际应用中，考虑三维控制的方便性，平移部件的移动方向垂直于铰接轴14。
请参见图4，在本申请的一些实施例中，平移机构16包括第二驱动电机161、主动带轮162、从动带轮163和传动皮带164。
第二驱动电机161固定在机架11上；主动带轮162设置在第二驱动电机161的输出端，通过中间传导机构与第二驱动电机161的输出端连接；从动带轮163设置在机架11上，并且其回转轴平行于主动带轮162的回转轴；传动皮带164架设在主动带轮162和从动带轮163之间，绕主动带轮162和从动带轮163回转。
传动皮带164即上段中提及的平移部件。本申请的一些实施例中，滑块125沿竖直方向上下移动，传动皮带164的移动方向为垂直于滑块125 竖直移动方向的第一水平方向。当然，如果滑块125并不沿竖直方向移动，传动皮带164仍然可以按照在水平方向移动，使吸盘在非工作状态时移动至不干涉其他部件动作的位置。
在本申请的一些实施例中，平移机构16还可以包括平行于传动皮带的延伸方向164设置的导向滑轨；升降驱动机构12的基座121与滑轨卡接连接、沿导向滑轨滑动，以利用导向滑轨限制随传动皮带164运行时的振动。
当然，在本申请的一些实施例中，平移机构16也可以采用机械领域的其它传动机构，并不限于前文描述。
本实施例中的平移机构16可能还会起到辅助掀起光伏芯片01的作用。在本申请的一些实施例中，在吸盘13吸附光伏芯片、带动光伏芯片上移的过程中，平移机构16可以带动升降驱动机构12向机架11中间位置移动，利用吸盘13的惯性、使吸盘13产生绕铰接轴14的转动运动，增大光伏芯片的转动角度。
为提高使用的经济性、提高生产效率。在本申请的一些实施例中，支架15的安装臂152上设置了多个吸盘13；多个吸盘13沿着安装臂152的延伸方向并列的设置，并且各个吸盘13的工作面位于同一平面。
为了适应不同型号的太阳能电池的组装，掀起装置中的支架15和滑块125可拆卸。因此可以配备多个不同尺寸、设置不同数量吸盘13的支架15。因为可能设置多个不同尺寸信号的支架15、适应不同型号太阳能电池的组装，吸嘴在图4所示的上下方向也可能需要移动。
为解决前段提及的问题，在本申请的一些实施例中，掀起装置包括位置调整机构17。如图4所示，位置调整机构17包括托板、第三驱动电机171、主动轮172、从动轮173和调整皮带174。其中托板安装在平移机构16的传动皮带164上，第三驱动电机171、主动轮172、从动轮173均安装在托板上；调整皮带174绕主动轮172和从动轮173回转。前述的升降驱动机构12的基座121安装在回转皮带上。
在第三驱动电机171的驱动下，调整皮带174可以带动升降驱动机构12移动；本申请的一些实施例中，调整皮带174的移动方向为垂直于传动皮带164移动方向的第二水平方向。与前文描述类似，其他实施例中，位 置调整机构17并不限于前述结构，也可以是机械领域的其他结构。
应当注意，为了考虑实际应用中的调整需求量，本实施采用前文表述的、图示的升降驱动机构12、平移机构16和位置调整机构17布置顺序和连接关系；考虑到三个机构的运动可能互不影响，在其他实施例中也可以更改三者的布置顺序和连接关系。
本实施例提供的掀起装置中，吸盘13可以自由地绕铰接轴14转动，即除了吸盘13重力、升降部件的驱动力以及光伏芯片的重力作用外，没有其他作用在吸盘13上的力量使吸盘13转动；在其他实施例中，还可以设置使吸盘13主动转动的旋转驱动机构。具体的，旋转驱动机构的一端与升降部件铰接连接，另一端与吸盘13或者支架15铰接连接；旋转驱动机构可以驱动吸盘13相对铰接轴14转动。结合具体使用时的受力分析可知，为避免光伏芯片的靠近基板内侧的侧边离开基板，采用旋转驱动机构时需要配合平移机构16的相应移动动作。
除了提供前述的掀起装置外，本实施例还提供一种采用前述掀起装置的太阳能电池焊接设备。图2-图4显示的即为太阳能电池焊接设备，其除了前述的掀起装置外，还包括承托基板和光伏芯片的组装台、焊接装置和汇流带供给装置。焊接装置设置在组装台的上侧。前文提及的掀起装置中，至少升降驱动结构的部分部件、吸盘13和支架15设置在组装台的上侧。
本申请的一些实施例中，掀起装置包括相对组装台固定的机架；升降驱动机构设置在机架上。
本申请的一些实施例中，组装台实际由多个承托滚轴组合形成，太阳能电池组件中的基板可以通过承托滚轴驱动上料；太阳能电池组装完成后，由承托滚轴驱动离开焊接设备。
焊接装置和汇流带供给装置可以采用本领域技术人员常用的设备，本申请不再描述。
应当注意，本申请实施例提供的掀起装置不仅可以应用在前述太阳能电池焊接设备中，也可以应用在具有类似掀起需求的场合。
以上描述仅为本申请的一些实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本申请中所涉及的发明范围，并不限于上述技术 特征的特定组合而成的技术方案，同时也应涵盖在不脱离上述发明构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本申请中公开的但不限于具有类似功能的技术特征进行互相替换而形成的技术方案。
