The exposed end of the object to be welded is limited laterally on the surface, and the lifting and moving module is used to quickly descend, so that the welding work surface strongly presses the exposed end to achieve precise ultrasonic bonding.

Description
本發明係提供一種焊接裝置,特別是關於一種用於焊接至少兩個線狀金屬端面的超音波焊接設備。The invention provides a welding device, in particular to an ultrasonic welding device for welding at least two linear metal end faces.
利用超音波高頻振動能量產生焊接效果是一種極常見的加工製程,例如是對於工業用電線(或者,例如多股引線/線束)的至少兩個電線/多股引線(線束),藉由超音波產生器達成該等金屬裸露端頭相互焊接一起。 其中,有一種設計是為了讓滑動更順暢以及承受強大變形應力,因此將用以升降移動模組設計為更接近於焊接工作區,達到短力臂、高抗扭曲的功能,但此等設計卻產生有必須多加注意其滑動裕度公差,以及因為滑動鬆配裕度,往往在大面積大壓力(即進行多條電線/多股引線/線束、或者較粗引線/線束狀況)焊接時在極大壓力下,因而撐開聚集模與工作喇叭的間隙、以及上模靠板與工作喇叭之間間隙,如此一來,勢必是加工製造非常精密的焊接加工設備,但又容易使保養、維修上較複雜,反之,倘若不是非常精密的加工製造時,又極容易因前述劣勢情況而產生不良焊接作動,或造成熔接後的工件/成品(例如由至少兩個多股引線的裸露端頭相互連接編結)發生毛胚過多的不良品質。The use of ultrasonic high-frequency vibration energy to produce welding effects is a very common processing process. The sonic generator achieves that the exposed metal ends are welded together. Among them, there is a design to make sliding smoother and withstand strong deformation stress. Therefore, the lifting and moving module is designed to be closer to the welding work area to achieve the function of short arm and high resistance to torsion, but these designs are not It is necessary to pay more attention to its sliding margin tolerance, and because of the sliding loose fitting margin, the large area and large pressure (ie, multiple wires/multi-stranded leads/harness, or thicker leads/harness conditions) are often used in welding. Under pressure, the gap between the gathering mold and the working horn, as well as the gap between the upper mold backing plate and the working horn, is opened. As a result, it is bound to process and manufacture very precise welding equipment, but it is easy to maintain and repair. Complex, on the contrary, if it is not very precise processing and manufacturing, it is very easy to cause poor welding action due to the aforementioned disadvantages, or cause welded workpieces/finished products (for example, at least two bare ends of multi-strand lead wires are connected to each other and braided ) Poor quality of excessive hair embryos.
另一種設計是為了使得製程能夠順暢,簡化保養工作,通常會將精密滾筒滑軌作為昇降機構的移動載具,但為了提供可承受極大抗扭曲應力的需求,必須選配體積較大型的滑軌結構,然而為了不佔據焊接工作區域太多空間,勢必將該滑軌結構“大幅遠離”該焊接裝置焊接工作區域的中心焊接位置,如此一來,不僅使該焊接裝置整體體積大幅變大,而且離焊接工作區較遠造成力臂長的滑軌結構在進行大負載力的焊接時,其偏擺度將非常大,在重載工作時致使焊接成品產生毛胚過多的現象。Another design is to make the process smooth and simplify the maintenance work. Usually the precision roller slide rail is used as the mobile carrier of the lifting mechanism. However, in order to provide the requirement to withstand great torsion stress, a larger slide rail must be selected. However, in order not to occupy too much space in the welding work area, the slide rail structure must be "substantially far away" from the center welding position of the welding work area of the welding device. As a result, not only the overall volume of the welding device is greatly increased, but also The sliding rail structure with long arm is far away from the welding work area, and its deflection will be very large when welding with large load force, which will cause excessive roughness in the welded product during heavy load work.

其中,如圖1、圖5,該氣動驅動系統,可為一般技術且非為本發明主要特徵故未完全例示於圖。在本實施例中,氣動驅動系統主要包含有一升降氣缸451(如圖1)及一橫向驅動氣缸452(如圖5)。如圖5,該升降氣缸451係連接並控制一氣缸桿4511,使氣缸桿4511上端可設置於該升降移動本體421下方的氣缸桿裝配槽423內(即氣缸桿4511上端連接於升降移動本體421下方的氣缸桿裝配槽423),使氣缸桿4511下端穿過升降座41下方的穿孔412並連接於該升降氣缸451,因而氣缸桿4511可被驅動而往上頂推、或往下拉移該升降移動本體421在升降座41的裝配孔411內上、下移動。如圖5,而該橫向驅動氣缸452係連接並控制該橫向移動模組43的裝配體431,用以驅動該裝配體431適時橫向位移功能。也就是說,通過該氣動驅動系統的橫向驅動氣缸452可驅動該橫向移動模組43(裝配體431、焊接體432)進行橫向移出該滑槽422外(或反向進入於滑槽422內)的橫向位移運動,以及升降氣缸451可驅動該氣缸桿4511拉動該升降移動本體421進行下降、或該氣缸桿4511頂推該升降移動本體421上升的升降位移運動。Among them, as shown in Figures 1 and 5, the pneumatic drive system may be a general technology and is not a main feature of the present invention, so it is not fully illustrated in the figures.
