具体实施方式detailed description
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。The following describes the present application in detail with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, but not to limit the invention.
图1是实施例提供的汇流带供给装置的正视图，图2是实施例提供的汇流带供给装置的后视图，图3是实施例提供的汇流带供给装置的轴侧图。如图1-图3所示，本申请实施例提供的汇流带供给装置包括安装板11、带卷安装机构和制动机构17。FIG. 1 is a front view of the busbar supply device provided in the embodiment, FIG. 2 is a rear view of the busbar supply device provided in the embodiment, and FIG. 3 is a perspective view of the busbar supply device provided in the embodiment. As shown in FIG. 1 to FIG. 3, the busbar supply device provided in the embodiment of the present application includes a mounting plate 11, a tape roll mounting mechanism, and a braking mechanism 17.
安装板11作为承载其他机构的基础，用于实现各个机构相对位置的固定，并将汇流带供给装置安装在太阳能电池组装设备的主体装置上。The mounting plate 11 serves as a basis for carrying other mechanisms, and is used to fix the relative positions of the various mechanisms, and the busbar supply device is installed on the main device of the solar cell assembly equipment.
带卷安装机构包括带卷回转轴12和带卷安装部13；带卷回转轴12设置在安装板11上，可以相对安装板11转动；带卷安装部13设置在带卷回转轴12上，随带卷回转轴12一同转动。The reel installation mechanism includes a reel rotation shaft 12 and a reel installation portion 13; the reel rotation shaft 12 is provided on the mounting plate 11 and can be rotated relative to the mounting plate 11; the reel installation portion 13 is provided on the reel rotation shaft 12, The reel shaft 12 rotates together with the reel.
制动机构17包括摩擦部A、摩擦制动部B和驱动部C。其中摩擦部A与带卷回转轴12固定连接，随带卷回转轴12转动。摩擦制动部B与驱动部C中的驱动部件连接，在驱动部C的作用下可以压靠在摩擦部上。The braking mechanism 17 includes a friction portion A, a friction braking portion B, and a driving portion C. The friction part A is fixedly connected to the reel rotating shaft 12 and rotates with the reel rotating shaft 12. The friction braking portion B is connected to a driving member in the driving portion C, and can be pressed against the friction portion by the driving portion C.
当摩擦部A随带卷回转轴12转动时，如果驱动部C带动摩擦制动部B压靠摩擦部A；摩擦部A和摩擦制动部B之间产生摩擦力，摩擦力作用在带卷回转轴12产生的转动力矩可以使带卷回转轴快速地停转。When the friction part A rotates with the belt rotating shaft 12, if the driving part C drives the friction braking part B to press against the friction part A; friction occurs between the friction part A and the friction braking part B, and the friction force acts on the belt winding The rotating moment generated by the rotating shaft 12 can quickly stop the reel rotating shaft.
在带卷安装部上可以安装汇流带卷，并且外界没有牵拉汇流带的动力时，制动机构使带卷回转轴12和带卷安装部13快速地停转，避免汇流带过量解缠绕而存留在后续装置中、造成后续装置卡滞等问题。When the busbar coil can be installed on the tape coil mounting section, and there is no power to pull the busbar, the braking mechanism quickly stops the rotary shaft 12 and the tape mounting section 13 to avoid excessive unwinding of the busbar. Remaining in the subsequent device, causing the subsequent device to become stuck.
具体的，本实施例中的制动机构包括摩擦轮171和牵拉绳172；其中，摩擦轮171固定在带卷回转轴12上，可以随带卷回转轴17转动。Specifically, the braking mechanism in this embodiment includes a friction wheel 171 and a pulling rope 172; wherein the friction wheel 171 is fixed on the reel rotating shaft 12 and can rotate with the reel rotating shaft 17.
在安装板11设置有两个定位销111，两个定位销111位于带卷回转轴12的同侧；牵拉绳172的两个自由端分别与两个定位销111固定连接，中间部分压靠在摩擦轮171上。本实施例中，牵拉绳172为弹性绳，并且其处于拉伸形变状态。Two positioning pins 111 are provided on the mounting plate 11, and the two positioning pins 111 are located on the same side of the reeled shaft 12. The two free ends of the pulling rope 172 are fixedly connected to the two positioning pins 111 respectively, and the middle part is pressed against On the friction wheel 171. In this embodiment, the pulling rope 172 is an elastic rope, and it is in a tensile deformation state.
因为牵拉绳172处于拉伸形变状态，所以牵拉绳172使得其中中间压 靠摩擦轮171的部分向摩擦轮171施加一定的压力；而当摩擦轮171转动时，前述压力使得摩擦轮171和牵拉绳172之间产生摩擦力；此摩擦力可以使摩擦轮171快速地停转，即实现带卷回转轴12的停转。Because the pulling rope 172 is in a state of tensile deformation, the pulling rope 172 causes a portion of the middle of the pulling rope 171 to apply a certain pressure to the friction wheel 171; and when the friction wheel 171 rotates, the aforementioned pressure causes the friction wheel 171 and A frictional force is generated between the pulling ropes 172; this frictional force can quickly stop the friction wheel 171, that is, the rotation of the reel shaft 12 is stopped.
根据前段可知，本实施例中牵拉绳172与摩擦轮171接触的部分即为前述的摩擦制动部B；牵拉绳172本身具有形变特性，其自身也包括驱动部C；对应的，摩擦轮171则为前述的摩擦部A。According to the previous paragraph, the portion of the pulling rope 172 in contact with the friction wheel 171 in this embodiment is the aforementioned friction braking portion B; the pulling rope 172 itself has deformation characteristics and also includes the driving portion C; correspondingly, the friction The wheel 171 is the aforementioned friction portion A.
本实施例中，牵拉绳172为处于拉伸形变状态的弹性绳，即牵拉绳172本身也为驱动部。在其他实施例中，还可以设置与牵拉绳172串联的拉伸弹性件，利用拉伸弹性件形变产生的拉力使牵拉绳172压靠在摩擦轮171上；实际应用中，拉伸弹性件优选采用拉簧。In this embodiment, the pulling rope 172 is an elastic rope in a tensile deformation state, that is, the pulling rope 172 is also a driving part. In other embodiments, a stretching elastic member connected in series with the pulling rope 172 may also be provided, and the pulling rope 172 is pressed against the friction wheel 171 by using the tensile force generated by the deformation of the stretching elastic member; in practical applications, the stretching elasticity The piece is preferably a tension spring.
当然，考虑到任何柔性绳件本身都具有一定的形变特性，牵拉绳172也可以采用常规的绳件，只是需要保证牵拉绳172始终处于拉紧状态并压靠在摩擦轮171上即可。Of course, considering that any flexible rope itself has certain deformation characteristics, the pulling rope 172 can also be a conventional rope, but it is only necessary to ensure that the pulling rope 172 is always in a tensioned state and pressed against the friction wheel 171. .
此外，在实际应用中，牵拉绳172本身可能较为光滑，因此其与摩擦轮171配合产生的摩擦力可能较小；为增大摩擦力，还可以在牵拉绳172与摩擦轮171配合的部分表面设置摩擦材料，利用摩擦材料作为摩擦制动部。In addition, in practical applications, the pulling rope 172 itself may be relatively smooth, so the friction force generated by the cooperation with the friction wheel 171 may be small. In order to increase the friction force, the pulling rope 172 may also cooperate with the friction wheel 171. A friction material is provided on a part of the surface, and the friction material is used as a friction braking portion.
本实施例中，摩擦轮171的外周侧还设置有环形导向槽；牵拉绳172与摩擦轮171配合的部分嵌入到环形导向槽内；如此，可以避免摩擦轮171转动时牵拉绳172脱离摩擦轮，提高运行的可靠性。In this embodiment, an outer circumferential side of the friction wheel 171 is further provided with an annular guide groove; a portion where the pulling rope 172 cooperates with the friction wheel 171 is embedded in the annular guide groove; in this way, the pulling rope 172 can be prevented from detaching when the friction wheel 171 rotates Friction wheels improve the reliability of operation.
本实施例中，两个定位销111安装在带卷回转轴12的同侧，而且二者的距离等于摩擦轮171的直径，使得牵拉绳172可以环绕摩擦轮171半圈。在其他实施中，两个定位销111的位置也可以变化，但只要使得牵拉绳172压靠摩擦轮即可。In this embodiment, the two positioning pins 111 are installed on the same side of the reel rotating shaft 12, and the distance between the two is equal to the diameter of the friction wheel 171, so that the pulling rope 172 can surround the friction wheel 171 half a circle. In other implementations, the positions of the two positioning pins 111 can also be changed, as long as the pulling rope 172 is pressed against the friction wheel.
应当注意，在其他实施例中也可以不设置前述的摩擦轮171，而是使牵拉绳172直接压靠在带卷回转轴12上；此时带卷回转轴12相应的部分也 就成为前述的摩擦部。另外，在其他实施例中，制动机构也可以不采用前述制动结构17，而是采用其他制动机构，例如采用鼓式刹车机构或者盘式刹车机构。It should be noted that, in other embodiments, the aforementioned friction wheel 171 may not be provided, but the pulling rope 172 may be directly pressed against the reel rotating shaft 12; at this time, the corresponding part of the reel rotating shaft 12 also becomes the aforementioned Friction part. In addition, in other embodiments, the braking mechanism may not use the foregoing braking structure 17 but other braking mechanisms, such as a drum brake mechanism or a disc brake mechanism.
如图1和图3所示，本实施提供的汇流带供给装置包括导引驱动机构14。As shown in FIG. 1 and FIG. 3, the busbar supply device provided in this embodiment includes a guide driving mechanism 14.
导引驱动机构14设置在带卷安装部13输出汇流带的一侧，包括主动导轮141、动力部件142和从动导轮143。其中，动力部件142与主动导轮141固定连接，可以驱动主动导轮141转动；实际应用中，动力部件142多为伺服电机，其转动速度和转动角度可以被精确的控制。The guide driving mechanism 14 is disposed on a side of the output bus belt of the tape roll mounting portion 13, and includes a driving guide wheel 141, a power member 142, and a driven guide wheel 143. Among them, the power component 142 is fixedly connected to the active guide wheel 141 and can drive the active guide wheel 141 to rotate. In practical applications, the power component 142 is mostly a servo motor, and its rotation speed and rotation angle can be accurately controlled.
主动导轮141和从动导轮143之间具有一间隙，此间隙的厚度大体等于汇流带的厚度。在正常工作中，主动导轮141和从动导轮143配合压紧汇流带，控制汇流带的向后续机构的供应量。There is a gap between the driving pulley 141 and the driven pulley 143, and the thickness of this gap is substantially equal to the thickness of the busbar. In normal work, the active guide wheel 141 and the driven guide wheel 143 cooperate to press the bus belt to control the supply amount of the bus belt to the subsequent mechanism.
如图1和图3所示，本实施例中提供的导引驱动机构14可以包括位置调整部件144；位置调整部件144安装在安装板上，用于调整主动导轮141和从动导轮143之间的间隙大小，适应不同厚度的汇流带，并方便汇流带的穿带操作。As shown in FIGS. 1 and 3, the guide driving mechanism 14 provided in this embodiment may include a position adjustment member 144; the position adjustment member 144 is installed on the mounting plate and is used to adjust the driving guide wheel 141 and the driven guide wheel 143. The size of the gap is suitable for the busbars of different thicknesses, and it is convenient for the busbars to pass through.
具体的，位置调整部件144与从动导轮143连接，驱动从动导轮143移动而改变间隙的大小。在其他实施例中，位置调整部件144也可以带动主动导轮141移动，但考虑到结构的简化和实际应用的可靠性，位置调整部件144优选与从动导轮143连接。Specifically, the position adjusting member 144 is connected to the driven guide wheel 143 and drives the driven guide wheel 143 to move to change the size of the gap. In other embodiments, the position adjusting member 144 can also drive the driving guide wheel 141 to move, but considering the simplification of the structure and the reliability of practical application, the position adjusting member 144 is preferably connected to the driven guide wheel 143.
另外，本实施例提供的汇流带供给装置中，导引驱动机构14还包括导向导轮145。导向导轮145设置在安装板11上，位于带卷安装部13和主动导轮141之间。In addition, in the busbar supply device provided in this embodiment, the guide driving mechanism 14 further includes a guide wheel 145. A guide roller 145 is provided on the mounting plate 11 and is located between the tape roll mounting portion 13 and the active guide roller 141.
实际应用中，随着设置在带卷安装部13中汇流带的解缠绕，汇流带从带卷安装部13的输出位置也相对发生变化；如果不设置导向导轮145，而直接使汇流带从带卷安装部13的输出端输送至主动导轮141和从动导轮 143之间的间隙，随着汇流带在带卷安装部13上的位置变化，汇流带现对于缝隙的角度发生变化，而前述角度变化则可能使在不调整主动导轮141和从动导轮143的情况下，主动导轮141和从动导轮143无法夹紧汇流带。In actual application, with the unwinding of the busbar provided in the tape roll installation portion 13, the output position of the busbar from the tape roll installation portion 13 also relatively changes; if the guide roller 145 is not provided, the busbar is directly driven from The output end of the tape installation portion 13 is conveyed to the gap between the driving guide wheel 141 and the driven guide wheel 143. As the position of the bus belt on the tape installation portion 13 changes, the angle of the bus belt with respect to the gap changes. The foregoing angle change may make it impossible for the active guide wheel 141 and the driven guide wheel 143 to clamp the busbar without adjusting the active guide wheel 141 and the driven guide wheel 143.
设置导向导轮145后，汇流带经过导向导轮145过渡后再伸入到前述间隙，而导向导轮145和前述主动导轮141的位置固定，汇流带从导向导轮145到间隙的偏转方向固定，所以可以避免前面提及的问题。After the guide wheel 145 is set, the bus belt extends into the gap after the guide wheel 145 transitions, and the positions of the guide wheel 145 and the active guide wheel 141 are fixed, and the deflection direction of the bus belt from the guide wheel 145 to the gap is fixed. Fixed so you can avoid the aforementioned issues.
除了前述结构外，本实施例提供的汇流带供给装置还可以包括裁刀机构15和压料机构16。In addition to the foregoing structure, the busbar supply device provided in this embodiment may further include a cutter mechanism 15 and a pressing mechanism 16.
裁刀机构15设置在主动导轮141和从动导轮143远离带卷安装部13的一侧，用于裁断从带卷安装部13上解缠绕的汇流带。The cutter mechanism 15 is disposed on a side of the driving guide wheel 141 and the driven guide wheel 143 away from the tape roll mounting portion 13, and is used to cut the bus bar unwound from the tape roll mounting portion 13.
压料机构16设置在裁刀机构15远离导引驱动机构14的一侧，压料机构16至少在裁刀机构15工作时压紧汇流带，防止汇流带在裁刀的裁切力驱动下反向移动，没有被切断。The material pressing mechanism 16 is disposed on the side of the cutter mechanism 15 away from the guide driving mechanism 14. The material pressing mechanism 16 presses the bus belt at least when the cutter mechanism 15 is in operation, so as to prevent the bus belt from reacting under the driving force of the cutter. Move to the direction without being cut.
裁刀机构15包括定裁刀部151、动裁刀部152和往复驱动部153。定裁刀部151和往复驱动部153均固定在安装板11上，动裁刀部152安装在往复驱动部153的往复运动件上，在往复运动件的驱动下相对定裁刀部151往复运动；定裁刀部151和动裁刀部152配合，实现对汇流带的剪切。The cutter mechanism 15 includes a fixed cutter section 151, a movable cutter section 152, and a reciprocating drive section 153. The fixed-knife section 151 and the reciprocating driving section 153 are both fixed on the mounting plate 11, and the movable cutting section 152 is mounted on the reciprocating member of the reciprocating driving section 153. ; The fixed cutter section 151 and the movable cutter section 152 cooperate to realize shearing of the busbar.
具体的，动裁刀部152的刃口位于靠近定裁刀部151的一侧，当动裁刀部152贴靠定裁刀部151时，刃口作用在汇流带上的剪切力使汇流带断裂。Specifically, the cutting edge of the movable cutter portion 152 is located on the side close to the fixed cutter portion 151. When the movable cutter portion 152 abuts against the fixed cutter portion 151, the shearing force of the cutting edge on the busbar causes the flow Belt breaks.
为了更好的固定汇流带，在定裁刀部151上可以设置汇流带定位槽或者汇流带定位孔；本实施例中，定裁刀部151上设置有汇流带定位孔(图中并未示出)，汇流带穿过主动导轮141和从动导轮143之间的缝隙后，直接进入到汇流带定位孔，继而输送至定裁刀部151和动裁刀部152配合的位置。In order to better fix the busbar, a busbar positioning groove or a busbar positioning hole may be provided on the cutting blade portion 151; in this embodiment, a busbar positioning hole is provided on the cutting blade portion 151 (not shown in the figure) (Out), after passing through the gap between the driving guide wheel 141 and the driven guide wheel 143, the busbar directly enters the busbar positioning hole, and is then conveyed to the position where the fixed cutter portion 151 and the movable cutter portion 152 cooperate.
如图4所示，本实施例中提供的汇流带供给装置中，压料机构16可以 包括压料基座161、压料块和压簧165；其中的压料块包括往复杆162、压靠部163和限位销164三部分。As shown in FIG. 4, in the busbar supply device provided in this embodiment, the pressing mechanism 16 may include a pressing base 161, a pressing block, and a pressing spring 165; the pressing block includes a reciprocating rod 162, a pressing There are three parts: 163 and limit pin 164.
在压料基座161上设置有贯通孔；往复杆162插入到贯通孔内，限位销164设置在往复杆162伸出贯通孔的一端，压靠部163设置在往复杆162伸出贯通孔的另一端；限位销164和压靠部163的截面尺寸大于贯通孔的截面尺寸，使往复杆162不会脱离贯通孔；压簧165设置在压靠部163和压料基座161之间，始终处于压缩状态。A through hole is provided on the pressing base 161; a reciprocating rod 162 is inserted into the through hole, a limit pin 164 is provided at an end of the reciprocating rod 162 protruding from the through hole, and a pressing portion 163 is provided on the reciprocating rod 162 extending from the through hole. The cross-section of the stop pin 164 and the pressing part 163 is larger than that of the through hole, so that the reciprocating rod 162 does not leave the through hole; the compression spring 165 is provided between the pressing part 163 and the pressing base 161 , Always compressed.
因为压簧165处于压缩状态，所以正常情况下压靠部163尽可能的远离压料基座161，能够压靠在从裁刀机构15输送而来的汇流带，保证裁切机构工作时汇流带不移动。当然，压簧165也可以设置在压料基座161和限位销164之间。Because the compression spring 165 is in a compressed state, normally the pressing portion 163 is as far away from the pressing base 161 as possible, and can be pressed against the bus belt conveyed from the cutter mechanism 15 to ensure that the bus belt is working when the cutting mechanism works. Don't move. Of course, the compression spring 165 may also be disposed between the pressing base 161 and the limit pin 164.
更为优选的，本实施例中的压料机构16还包括压料辊轮166；压料辊轮166设置在压靠部163上，并可以相对压靠部163转动。压料辊轮166除了可以保证裁切机构工作时汇流带不移动，还可以保证汇流带供给装置向外方便地输送汇流带。即压料辊轮166也起到了导向轮的作用。More preferably, the pressing mechanism 16 in this embodiment further includes a pressing roller 166; the pressing roller 166 is disposed on the pressing portion 163 and can rotate relative to the pressing portion 163. The pressing roller 166 can not only ensure that the busbar does not move when the cutting mechanism works, but also ensure that the busbar supply device can conveniently transport the busbar outward. That is, the nip roller 166 also functions as a guide wheel.
本实施例中，压料机构16能够适应不同厚度的汇流带，并且能够适应汇流带高度的变化，减小工作时对太阳能电池组装设备中工作台面的冲击。在其他实施例中，压料结构也可以直接采用压料辊轮166，而不采用前述的压料机构16。In this embodiment, the pressing mechanism 16 can adapt to busbars of different thicknesses, and can adapt to changes in the height of the busbars to reduce the impact on the work surface of the solar cell assembly equipment during work. In other embodiments, the pressing structure can also directly use the pressing roller 166 instead of the aforementioned pressing mechanism 16.
因为汇流带为金属条带，其具有一定的挺度。为了使得汇流带能够从裁刀机构15准确的输送至压料机构16的压料辊轮166下侧，本实施例提供的汇流带供给装置还包括导向块。Because the busbar is a metal strip, it has a certain stiffness.
