Detailed Description
Example 1: referring to fig. 1-6, an automatic tin surface tracking mechanism of an inductance tin soldering machine comprises a horizontal driving mechanism 3, and a first manipulator 1 and a second manipulator 2 which are arranged on the horizontal driving mechanism 3, wherein the first manipulator 1 comprises a first vertical driving mechanism 11, a first rotary driving mechanism 12 and a first clamping mechanism 13 which are sequentially connected in a driving manner, and the second manipulator 2 comprises a second vertical driving mechanism 21, a second rotary driving mechanism 22 and a second clamping mechanism 23 which are sequentially connected in a driving manner; the first vertical driving mechanism 11 and the second vertical driving mechanism 21 both adopt linear driving structures driven by servo motors, a first tin surface detection part 14 is fixedly arranged at the tail end of the first clamping mechanism 12, and a second tin surface detection part 24 is fixedly arranged at the tail end of the second clamping mechanism 22.
In this embodiment, a first manipulator 1 and a second manipulator 2 respectively perform dip soldering on pins at two ends of an inductance element, wherein the first manipulator 1 and the second manipulator 2 have the same structure and are both arranged on a horizontal driving mechanism 3, when soldering the inductance, the horizontal driving mechanism 3 drives the first manipulator 1 to move leftwards to clamp the inductance element to be soldered, then drives the first manipulator 1 to perform first soldering on the tin furnace, then controls the second manipulator 2 to be close to the first manipulator 1 to clamp the soldered end of the inductance element on the first manipulator 1, then simultaneously moves leftwards to move the first manipulator 1 and the second manipulator 2, the second manipulator 2 moves to the upper side of the tin furnace to perform soldering on the other end of the inductance element, at this time, the first manipulator 1 performs an action of clamping a new batch of inductance element to be soldered, and finally the second manipulator 2 and the first manipulator 1 move rightwards simultaneously, the second manipulator 2 puts down the welded inductance element, and the first manipulator 1 welds the inductance element which is just clamped for one time, so that the welding procedure is completed on the inductance element. Specifically, when the first manipulator 1 clamps the inductance element, the first rotary driving mechanism 12 on the first manipulator 1 drives the first clamping mechanism 13 to rotate to the left to the horizontal position, and the first vertical driving mechanism 11 drives the first clamping mechanism 13 to the height position where the inductance element is placed for clamping, when the inductance element is immersed in a tin furnace for welding, the first rotary driving mechanism 12 drives the first clamping mechanism 13 to vertically downwards, the first vertical driving mechanism 11 drives the clamping device to extend the pin of the inductance element into the tin furnace for welding, when the second manipulator 2 receives the inductance element which is welded once from the first manipulator 1, the second rotary driving mechanism 22 drives the second clamping mechanism 23 to rotate to the left to the horizontal direction, the first rotary driving mechanism 12 drives the first clamping mechanism 13 to rotate to the right to the horizontal direction, the second clamping mechanism 23 clamps the end of the inductance component clamped by the first clamping mechanism 13, then the first clamping mechanism 13 releases the inductance component, thereby completing the transfer of the inductance component, and after the second manipulator 2 performs the secondary welding on the inductance component, the second rotary driving mechanism 22 drives the second clamping mechanism 23 to rotate rightwards to the horizontal direction and put down the inductance component. When the first manipulator 1 is used for soldering an inductive element, the first tin surface detection part 14 arranged on the first clamping mechanism 13 is used for detecting a tin surface and controlling the depth of the first vertical driving mechanism 11 for driving the clamping mechanism to descend according to the detection result, when the first tin surface detection part 14 detects the tin material, namely when the tin material is touched, the inductive element on the first clamping mechanism 13 is just immersed in the tin material, and the first vertical driving mechanism 11 stops driving the first clamping mechanism 13 to descend, because the first vertical driving mechanism 11 adopts a linear driving structure driven by a servo motor, real-time control can be carried out according to a detection signal of the first tin surface detection part 14, namely, when the first tin surface detection part 14 does not detect the tin surface, the first vertical driving mechanism 11 continues to drive the first clamping mechanism 13 to descend, and when the first tin surface detection part 14 detects the tin surface, the first vertical driving mechanism 11 can stop, thereby ensuring that the pins of the inductance element are immersed in the tin material for welding; the welding of the inductance element by the second manipulator 2 is also the same as the welding principle of the first manipulator 1, and is not described herein. Because the first vertical driving mechanism 11 and the second vertical driving mechanism 21 adopt a linear driving structure driven by a servo motor, the first tin surface detection part 14 is arranged at the tail end of the first clamping mechanism 13, the second tin surface detection part 24 is arranged at the tail end of the second clamping mechanism 23, the first vertical driving mechanism 11 and the second vertical driving mechanism 21 can control the descending depth in real time according to a tin surface signal detected by the first tin surface detection part 14 or the second tin surface detection part 24, ensure that pins of an inductance element can be immersed in a tin material for welding, and do not need to frequently check the tin surface height and check whether the inductance element is subjected to false welding or not manually, thereby greatly improving the production efficiency and quality, greatly reducing the labor intensity and technical difficulty of operators, and one operator can simultaneously operate a plurality of devices to improve the production efficiency, the labor cost is reduced.
