The copper foil C can also be driven by the cutting structure 223 to cut the copper foil C. The hinge structure 223 includes a first link hinged with the output end of the first cylinder 222, and the first link is simultaneously cut with the copper foil C. The cutter 221 is hinged, and the cutter 221 has two hinged holes, one of which is hinged to the first link and one of which is hinged to the locked pin. The copper foil holding portion 21 and the copper foil cutting portion 22 can be driven by the second cylinder 224 to protrude toward the copper foil C from a direction perpendicular to the feeding direction X of the copper foil C in the horizontal direction.
另外，铜箔送出部20包括可驱动铜箔夹持部21、铜箔裁切部22沿铜箔C的送出方向X来回运动的第二驱动部23，第二驱动部23的驱动行程设置为容许由铜箔夹持部21夹持的铜箔C横跨变压器T且部分伸出于变压器T后贴合至变压器T。Further, the copper foil delivery portion 20 includes a second driving portion 23 that can drive the copper foil clamping portion 21 and the copper foil cutting portion 22 to move back and forth in the feeding direction X of the copper foil C, and the driving stroke of the second driving portion 23 is set to The copper foil C sandwiched by the copper foil holding portion 21 is allowed to straddle the transformer T and partially protrudes from the transformer T, and is attached to the transformer T.
参照图2、图3，在一种实施例中，第一机械手14将变压器旋转部10转移至铜箔C的下部，第一机械手14上还设置有举升部15，举升部15通过气缸或者电机驱动举升，变压器旋转部10设置在举升部15上，并通过举升部15将变压器旋转部10举升以使变压器T贴合至铜箔C。变压器T贴合铜箔C后，由于铜箔C横跨变压器T且部分伸出变压器T，变压器旋转部10的伺服电机11可以沿与铜箔C包裹变压器T时的旋转方向相反的方向旋转变压器T，以使部分伸出变压器T的铜箔C完全贴合至变压器T。通过这样，可以在铜箔C没有张力的情况下，使铜箔C和变压器T尽可能大面积地贴合，防止铜箔C与变压器T的贴合面积过小、张力过大导致铜箔C包裹变压器T时脱落。Referring to Figures 2 and 3, in one embodiment, the first robot 14 transfers the transformer rotating portion 10 to the lower portion of the copper foil C, and the first robot 14 is further provided with a lifting portion 15 through which the lifting portion 15 passes. Alternatively, the motor is driven to lift, the transformer rotating portion 10 is disposed on the lift portion 15, and the transformer rotating portion 10 is lifted by the lift portion 15 to bond the transformer T to the copper foil C. After the transformer T is attached to the copper foil C, since the copper foil C straddles the transformer T and partially protrudes from the transformer T, the servo motor 11 of the transformer rotating portion 10 can rotate the transformer in a direction opposite to the rotation direction when the copper foil C wraps the transformer T. T, so that the copper foil C partially protruding from the transformer T is completely attached to the transformer T. In this way, when the copper foil C has no tension, the copper foil C and the transformer T can be bonded as much as possible, and the bonding area of the copper foil C and the transformer T can be prevented from being too small, and the tension is too large to cause the copper foil C. When the transformer T is wrapped, it falls off.
进一步地，第二驱动部23还可以驱动铜箔送出部20在夹持铜箔C及裁切铜箔C之间切换，因此，第二驱动部23优选地使用电机驱动的滑台模组，以实现铜箔送出部20可以多点启停，同时，电机可以控制其启动速度及停止速度，平缓动作，防止如气缸等可能出现的急剧伸出问题导致把铜箔C扯断。Further, the second driving portion 23 can also drive the copper foil feeding portion 20 to switch between the clamping copper foil C and the cutting copper foil C. Therefore, the second driving portion 23 preferably uses a motor-driven sliding table module. In order to realize the copper foil feeding portion 20, the motor can control the starting speed and the stopping speed, and the movement can be smoothly operated to prevent the copper foil C from being torn off due to a sudden protruding problem such as a cylinder.
更进一步地，为了避免铜箔夹持部21及铜箔裁切部22在铜箔C的送出方向X干涉到铜箔C的送出，铜箔送出部20还可以包括可驱动铜箔夹持部21及铜箔裁切部22在铜箔C的上下方向来回运动的第三气缸225，即第二驱动部23、第二气缸224及第三气缸225可以构成为三轴机械手，该三轴机械手分别沿铜箔C的送出方向X、沿在水平方向上与铜箔C的送出方向X垂直的方向及沿铜箔C的上下方向来回驱动。 Further, in order to prevent the copper foil sandwiching portion 21 and the copper foil cutting portion 22 from interfering with the feeding of the copper foil C in the feeding direction X of the copper foil C, the copper foil feeding portion 20 may further include a driveable copper foil holding portion. 21 and the third cylinder 225 in which the copper foil cutting portion 22 moves back and forth in the vertical direction of the copper foil C, that is, the second driving portion 23, the second cylinder 224, and the third cylinder 225 may be configured as a three-axis robot, and the three-axis robot The driving direction X of the copper foil C is driven back and forth along the direction perpendicular to the feeding direction X of the copper foil C in the horizontal direction and in the vertical direction of the copper foil C.
参照图1、图2，检测部30设置在当铜箔C包裹变压器T时可检测铜箔C有无的位置，设置检测部30主要用于实时监控铜箔C包裹变压器T时的工作状态，由于铜箔C包裹变压器T时，铜箔送出部20跟变压器T之间始终具有张力，因此，其送出位置在张力的作用下可以确定，即在铜箔送出部20及变压器T之间，铜箔C始终与铜箔C的预先设定的送出方向X一致。而当出现铜箔C被拉断或者铜箔C从变压器T上脱落等情况时，失去张力的铜箔C会偏离的预先设定的送出方向X，因此，通过设置检测部30检测该区域的铜箔C的有无，可以切实地监控铜箔C包裹变压器T时的工作状态，并反馈输出信息，如报警信息，提示作业者处理不良品。Referring to FIGS. 1 and 2, the detecting portion 30 is provided at a position where the presence or absence of the copper foil C can be detected when the copper foil C wraps the transformer T. The setting detecting portion 30 is mainly used for real-time monitoring of the working state when the copper foil C wraps the transformer T. Since the copper foil C wraps the transformer T, the copper foil sending portion 20 always has tension between the transformer T and the transformer T. Therefore, the feeding position can be determined by the tension, that is, between the copper foil sending portion 20 and the transformer T, copper. The foil C always coincides with the predetermined feed direction X of the copper foil C. When the copper foil C is pulled off or the copper foil C is detached from the transformer T, the copper foil C that has lost the tension deviates from the predetermined delivery direction X, and therefore, the detection portion 30 detects the region. The presence or absence of the copper foil C can reliably monitor the working state of the copper foil C when the transformer T is wrapped, and feed back the output information, such as an alarm message, prompting the operator to handle the defective product.
在检测部30的一种实施例中，检测部30包括反射型光电传感器，反射型光电传感器设置在可通过照射铜箔C的表面检测铜箔C有无的位置，当然检测铜箔C有无的非接触式传感器同样可以选择对射型光电传感器或者激光位移传感器。反射型光电传感器可以设置在铜箔送出部20上，可以设置在安装基座200上，可以设置在铜箔C的上部，也可以设置在铜箔C的下部，只要其距离铜箔C的表面距离在反射型光电传感器的检测范围之内，本领域普通技术人员可以根据需求自己选择安装位置。当然，在检测部30的别的实施例中，检测部30还可以使用如微动开关、接触式位移传感器等。而当检测部30使用微动开关或者接触式位移传感器时，可以将微动开关或者接触式位移传感器设置在铜箔C的上表面或者下表面，并利用其本身的弹性进一步对铜箔C施加一定的张力。以确保铜箔C包裹变压器T时由于张力的作用可与变压器T始终贴合。In an embodiment of the detecting unit 30, the detecting unit 30 includes a reflective photoelectric sensor, and the reflective photoelectric sensor is disposed at a position where the surface of the copper foil C can be detected by the surface of the copper foil C. Of course, the presence or absence of the copper foil C is detected. The non-contact sensor can also be selected as a pair of photoelectric sensors or laser displacement sensors. The reflective photosensor may be disposed on the copper foil delivery portion 20, may be disposed on the mounting base 200, may be disposed on the upper portion of the copper foil C, or may be disposed on the lower portion of the copper foil C as long as it is away from the surface of the copper foil C. The distance within the detection range of the reflective photoelectric sensor can be selected by one of ordinary skill in the art according to the needs. Of course, in another embodiment of the detecting unit 30, the detecting unit 30 may also use, for example, a micro switch, a contact type displacement sensor, or the like. When the detecting portion 30 uses a micro switch or a contact type displacement sensor, the micro switch or the contact type displacement sensor may be disposed on the upper surface or the lower surface of the copper foil C, and the copper foil C may be further applied by its own elasticity. A certain tension. In order to ensure that the copper foil C wraps the transformer T, it can always fit with the transformer T due to the tension.
另外，检测部30还可以包括检测变压器旋转部10是否有变压器T的传感器，检测变压器T的传感器优选非接触式的传感器，如激光位移传感器、反射型光电传感器、对射型光电传感器等。Further, the detecting unit 30 may further include a sensor that detects whether or not the transformer rotating portion 10 has the transformer T. The sensor that detects the transformer T is preferably a non-contact type sensor such as a laser displacement sensor, a reflective photoelectric sensor, a through-beam photoelectric sensor, or the like.
参照图2，为了进一步切实地确保铜箔C包裹变压器T时可紧紧地贴合变压器T，铜箔C包裹变压器T时也可以使用滚轮压紧部40压紧。同时，因为滚轮压紧部40的存在，铜箔C本身的张力也可以稍微减小，以防止因为张力过大导致铜箔C被扯断。滚轮压紧部40可从铜箔C的与变压器T相反的一侧将铜箔C压紧贴合至变压器T。优选地，铜箔C设置为水平方向送出，变压器旋转部10驱动变压器T绕伺服电机11的输出轴竖直方向旋转，滚轮压紧部40从铜箔C的上部朝下将铜箔C压紧贴合至变压器T。Referring to Fig. 2, in order to further securely ensure that the copper foil C wraps the transformer T tightly, the transformer T can be tightly attached, and when the copper foil C wraps the transformer T, the roller pressing portion 40 can be pressed. At the same time, the tension of the copper foil C itself can be slightly reduced due to the presence of the roller pressing portion 40 to prevent the copper foil C from being torn due to excessive tension. The roller pressing portion 40 presses the copper foil C against the transformer T from the side of the copper foil C opposite to the transformer T. Preferably, the copper foil C is disposed to be fed in the horizontal direction, the transformer rotating portion 10 drives the transformer T to rotate in the vertical direction around the output shaft of the servo motor 11, and the roller pressing portion 40 presses the copper foil C from the upper portion of the copper foil C downward. Fit to transformer T.
在滚轮压紧部40的一种优选实施例中，滚轮压紧部40包括压紧铜箔C的滚轮41，由于变压器T的圆周尺寸并非一致，可能是椭圆形、方形、甚至是非规则的形状，为了使滚轮41在变压器T旋转时不会与变压器T发生大的碰撞甚至卡滞，滚轮41通过第一柔性体42连接至可驱动滚轮41抵接至铜箔C的与变压器T相反的一侧的第一驱动部43。第一柔性体42可以是螺旋弹簧、油压缓冲器、氮气弹簧、具有大的变形量的硅胶、聚氨酯等，当变压器T的形状差异过大时，优选具有长弹性行程的螺旋弹簧。第一驱动部43可以使用气缸或者电机驱动，在举升部15将变压器T举升贴合至铜箔C后，第一驱动部43驱动滚轮41下落抵接至铜箔C。当然，第一柔性体42同样可以选择气缸，通过调节气缸的气压，调节气缸的输出力以实现滚轮41根据变压器T的旋转轨迹自动伸缩。In a preferred embodiment of the roller pressing portion 40, the roller pressing portion 40 includes a roller 41 that presses the copper foil C. Since the circumferential dimension of the transformer T is not uniform, it may be an elliptical, square, or even irregular shape. In order to prevent the roller 41 from colliding or even getting stuck with the transformer T when the transformer T rotates, the roller 41 is connected to the opposite of the transformer T by the first flexible body 42 to the driveable roller 41 abutting against the copper foil C. The first driving portion 43 on the side. The first flexible body 42 may be a coil spring, a hydraulic shock absorber, a nitrogen gas spring, a silica gel having a large deformation amount, a polyurethane, or the like. When the shape difference of the transformer T is excessively large, a coil spring having a long elastic stroke is preferable. The first drive unit 43 can be driven by a cylinder or a motor. After the lift unit 15 lifts and lifts the transformer T to the copper foil C, the first drive unit 43 drives the roller 41 to fall against the copper foil C. Of course, the first flexible body 42 can also select a cylinder. By adjusting the air pressure of the cylinder, the output force of the cylinder is adjusted to realize the automatic expansion and contraction of the roller 41 according to the rotation trajectory of the transformer T.
参照图4、图5，为了在铜箔送出部20送出铜箔C时对铜箔C进行导向，还包括用于辅助铜箔C送出的辅助辊筒组50及用于安装辅助辊筒组50的辊筒安装座51，辅助辊筒组50包括第一辊筒52及与第一辊筒52相对设置以夹持住铜箔C的第二辊筒53。进一步地，第一辊筒52滚动面的两侧面上设置有用于铜箔C定位的挡块521以限制铜箔C送出时偏摆。为了调试出第一辊筒52及第二辊筒53夹持铜箔C时的最佳力度，第二辊筒53可以设置为可调节型，调节可以使用本领域普通技术人员所公知的腰型孔调节。对于部分铜箔C而言，其上面可能粘贴有胶纸，粘贴有胶纸段的铜箔C的厚度与没粘贴胶纸的铜箔C的厚度不一致，为了防止粘贴有胶纸的铜箔C在辅助辊筒组50处卡滞导致铜箔C被扯断，辅助辊筒组50上还设置有第二柔性体522，第二辊筒53通过第二柔性体522连接至辊筒安装座51，以实现第二辊筒53根据铜箔C的厚度自调节。同样地，第二柔性体522可以是螺旋弹簧、油压缓冲器、氮气弹簧、具有大的变形量的硅胶、聚氨酯等，由于粘贴有胶纸段的铜箔C的厚度与没粘贴胶纸的铜箔C的厚度差异通常在3mm以下，因此，第二柔性体522可以选择具有大的变形量的硅胶或者聚氨酯。当然，第二辊筒53本身也可以使用硅胶或者聚氨酯材质设置。4 and 5, in order to guide the copper foil C when the copper foil C is sent out by the copper foil feeding portion 20, the auxiliary roller group 50 for assisting the feeding of the copper foil C and the auxiliary roller group 50 for mounting are further included. The roller mount 51, the auxiliary roller set 50 includes a first roller 52 and a second roller 53 disposed opposite the first roller 52 to clamp the copper foil C. Further, stoppers 521 for positioning the copper foil C are provided on both side faces of the rolling surface of the first roller 52 to restrict the deflection of the copper foil C when it is sent out. In order to revise the optimum force when the first roller 52 and the second roller 53 hold the copper foil C, the second roller 53 may be provided in an adjustable type, and the adjustment may use a waist shape known to those skilled in the art. Hole adjustment. For some copper foils C, adhesive paper may be adhered to the upper surface thereof, and the thickness of the copper foil C to which the adhesive tape is pasted is inconsistent with the thickness of the copper foil C to which the adhesive paper is not attached, in order to prevent the copper foil C to which the adhesive tape is pasted. The stuck at the auxiliary roller set 50 causes the copper foil C to be torn off, and the auxiliary roller set 50 is further provided with a second flexible body 522 which is connected to the roller mount 51 via the second flexible body 522. To achieve the second roller 53 self-adjusting according to the thickness of the copper foil C. Similarly, the second flexible body 522 may be a coil spring, a hydraulic buffer, a nitrogen gas spring, a silica gel having a large deformation amount, a polyurethane, or the like, due to the thickness of the copper foil C to which the adhesive tape segment is pasted and the adhesive paper not attached. The difference in thickness of the copper foil C is usually 3 mm or less, and therefore, the second flexible body 522 can be selected from silica gel or polyurethane having a large amount of deformation. Of course, the second roller 53 itself can also be provided using a silicone or polyurethane material.
另外，当送出的铜箔C较长时，由于铜箔C距离铜箔C包裹变压器T处越远，其越容易偏摆，因此，为了防止铜箔C的偏摆，还可以包括设置在铜箔C的送出方向X的具有真空吸孔（未图示）的第二定位块60，铜箔C经由第二定位块60的真空吸孔（未图示）吸附后被辅助辊筒组50夹持。当然，第二定位块60同样可以设置在别的地方，如铜箔C从辅助辊筒组50贯穿出来后，同样可以经由第二定位块60的真空吸孔（未图示）的吸附，被铜箔夹持部21夹持。In addition, when the copper foil C to be sent out is long, the farther the copper foil C is from the copper foil C to the transformer T, the more easily it is yawed. Therefore, in order to prevent the deflection of the copper foil C, it may be included in the copper. The second positioning block 60 having a vacuum suction hole (not shown) in the feeding direction X of the foil C is adsorbed by the vacuum suction hole (not shown) of the second positioning block 60 and then clamped by the auxiliary roller group 50. hold. Of course, the second positioning block 60 can also be disposed elsewhere. For example, after the copper foil C is penetrated from the auxiliary roller group 50, it can also be adsorbed through the vacuum suction hole (not shown) of the second positioning block 60. The copper foil holding portion 21 is sandwiched.
