The starting position of the stripping paint assembly 53 is rotated. The specific principles are as follows:
参见图23,设定O1为焊接点,O2为原点,O3为剥漆开始点,O1与O2之间的距离为L0,L0、S为已知数,则可以根据以下公式得到L1的距离,即旋转剥漆组件53开始剥漆时,丝杠组件的滑块543的运动距离。Referring to Fig. 23, set O1 as the welding point, O2 is the origin, O3 is the starting point of stripping paint, the distance between O1 and O2 is L0, L0, S are known numbers, then the distance of L1 can be obtained according to the following formula.

公式:L1=[INT(L0/S)+1]×S-L0Formula: L1=[INT(L0/S)+1]×S-L0
上述公式中,L1为剥漆开始点至原点的位置,L0为原点与焊接点的位置,S为用户设定的灯距,INT(L0/S)即取L0除于S商的整数。例如:设L0为180mm,S为50mm,则L1=[INT(180/50)+1]×50-180=20mm。In the above formula, L1 is the position from the starting point of the stripping paint to the origin, L0 is the position of the origin and the solder joint, S is the lamp distance set by the user, and INT(L0/S) is the integer of L0 divided by the S quotient. For example, if L0 is 180 mm and S is 50 mm, then L1=[INT(180/50)+1]×50-180=20 mm.

如图31所示,本实施例中的焊接检测机构的工作原理如下:焊接机构将贴片LED110的正极1101和负极1102分别对应正极导线和负极导线的焊灯区进行焊接。因为LED灯串采用的是等间距并联焊接,所以当正极探针631和负极探针632通电时,正极探针631和负极探针632给正极导线和负极导线供电,灯串上的贴片LED1、贴片LED2、贴片LED3、…、贴片LEDN会同时带电,分别会出现发光与不发光两种状态。焊接检测组件62的镜头621实时捕捉贴片LED1的通电状态,并反馈给设备系统进行判断,检测到贴片LED1发亮是良品时,灯串继续流入下一工位,检测到贴片LED1不发亮时,系统发出信号给激光控制器,激光头发出激光再次对贴片LED1与导线进行补焊1次,不良补焊次数可以根据设备系统进行 设置,然后,流入下一工位。由此可见,本实施例中的焊接检测机构,采用LED导线灯串在线检测与补焊模式,使LED导线灯串自动化生产中实时返工,解决了在制程过程中,灯珠与导线焊接不良所造成成品不良率,大幅提高灯串生产的良品出货率。As shown in FIG. 31, the working principle of the welding detecting mechanism in this embodiment is as follows: the welding mechanism welds the positive electrode 1101 and the negative electrode 1102 of the patch LED 110 to the soldering lamp regions of the positive electrode and the negative electrode, respectively. Since the LED string is equally spaced parallel welding, when the positive probe 631 and the negative probe 632 are energized, the positive probe 631 and the negative probe 632 supply power to the positive and negative leads, and the patch LED 1 on the string. , SMD LED2, SMD LED3, ..., SMD LEDN will be charged at the same time, respectively, there will be two states of illuminating and non-illuminating. The lens 621 of the soldering detection component 62 captures the power-on state of the patch LED1 in real time, and feeds back to the device system for judgment. When detecting that the patch LED1 is bright, the light string continues to flow into the next station, and the patch LED1 is detected. When it is lit, the system sends a signal to the laser controller. The laser hair laser re-welds the patch LED1 and the wire once. The number of bad repairs can be set according to the equipment system, and then flows into the next station. It can be seen that the welding detection mechanism in the embodiment adopts the on-line detection and repair welding mode of the LED wire lamp string, so that the LED wire lamp string can be reworked in real time in the automatic production, and the welding of the lamp bead and the wire is poor in the process of the process. This will result in a defective product rate and a significant increase in the shipment rate of light string production.

Moreover, using the welding detection component 62 to determine whether there is a lamp bead? Is the wire stripping good? Is there solder? Is the patch LED aligned correctly with the wire? Does the LED shine? It solves the defect rate of finished products caused by poor soldering of lamp beads and copper wires during the process, and greatly improves the good product shipment rate of lamp string production.
