(1) Improve accuracy and ensure high-speed welding.

企業(yè)在生產(chǎn)中送餐機(jī)器人意味著追求效率高 、高焊接質(zhì)量，因此在焊接速度上尋求突破，而機(jī)器人在軌跡控制上的高精度是高速焊接的可靠保證。

In the production of enterprises, the meal delivery robot means to pursue high efficiency and high welding quality, so it seeks a breakthrough in welding speed, and the high precision of robot trajectory control is the reliable guarantee of high-speed welding.

(2)雙機(jī)協(xié)調(diào)焊接功能。

(2) Dual machine coordinated welding function.

有時(shí)我們會(huì)遇到長(zhǎng)形工件，焊縫分布在工件的兩端，若采用1臺(tái)機(jī)器人進(jìn)行焊接，會(huì)出現(xiàn)因兩端不同時(shí)焊接而造成焊接變形不一致，從而使工件在長(zhǎng)度方向上扭轉(zhuǎn)變形，焊接后的工件難以符合尺寸要求。針對(duì)這種類(lèi)型的工件，我們常采用2臺(tái)機(jī)器人同時(shí)協(xié)調(diào)焊接的方式，這就促生了兩臺(tái)機(jī)器人雙機(jī)協(xié)調(diào)焊接技術(shù)。在汽車(chē)后橋和消聲器的焊接中，經(jīng)常會(huì)使用到該項(xiàng)技術(shù)。2臺(tái)機(jī)器人對(duì)應(yīng)1個(gè)由機(jī)器人外部軸驅(qū)動(dòng)的變位機(jī)，在變位機(jī)順長(zhǎng)擺放的工件上有兩個(gè)鏡像對(duì)稱(chēng)的部件，兩條相似的環(huán)焊縫需要兩臺(tái)機(jī)器人在變位機(jī)旋轉(zhuǎn)的同時(shí)實(shí)現(xiàn)同步協(xié)調(diào)焊接，通過(guò)這種方式可以將焊接生產(chǎn)的效率提高1倍。

Sometimes we will encounter long workpieces with welds distributed at both ends of the workpiece. If one robot is used for welding, there will be inconsistent welding deformation due to different welding at both ends, resulting in torsional deformation of the workpiece in the length direction, and the workpiece after welding is difficult to meet the size requirements. For this type of workpiece, we often adopt the method of coordinated welding of two robots at the same time, which promotes the coordinated welding technology of two robots and two machines. This technology is often used in the welding of automobile rear axle and muffler. Two robots correspond to a positioner driven by the external axis of the robot. There are two mirror symmetrical parts on the workpiece placed along the length of the positioner. Two similar circumferential welds require two robots to realize synchronous and coordinated welding while the positioner rotates. In this way, the efficiency of welding production can be doubled.

(3)點(diǎn)焊機(jī)器人的優(yōu)勢(shì)。

(3) Advantages of spot welding robot.

如果說(shuō)弧焊機(jī)器人的使用大大提高了焊接質(zhì)量的穩(wěn)定性和焊接效率，點(diǎn)焊機(jī)器人則具有更多的優(yōu)勢(shì)，帶來(lái)的經(jīng)濟(jì)效益也更加可觀，主要體現(xiàn)在：

If the use of arc welding robot greatly improves the stability of welding quality and welding efficiency, spot welding robot has more advantages and brings more considerable economic benefits, mainly reflected in:

A.機(jī)器人點(diǎn)焊時(shí)，大多采用鉗體與變壓器一體方式，變壓器的容量可以減小到1/3～1/4，節(jié)約了能源，并且很大程度上減輕了操作者繁重的體力勞動(dòng)。

A. During robot spot welding, the clamp body and transformer are mostly integrated, and the capacity of the transformer can be reduced to 1 / 3 ~ 1 / 4, which saves energy and reduces the heavy manual labor of the operator to a great extent.

B.點(diǎn)焊機(jī)器人有更多的控制方式控制焊鉗壓力和焊接條件的自動(dòng)切換，針對(duì)不同打點(diǎn)位置可輕松實(shí)現(xiàn)獨(dú)特的焊接時(shí)序，大大提高了打點(diǎn)質(zhì)量，避免了焊點(diǎn)漏打、多打及位置不準(zhǔn)確等問(wèn)題。

B. The spot welding robot has more control modes to control the automatic switching of welding clamp pressure and welding conditions. It can easily realize the unique welding sequence for different spot welding positions, greatly improve the spot welding quality, and avoid the problems of missing, multiple and inaccurate position of welding spots.

C.點(diǎn)焊機(jī)器人在打點(diǎn)效率上的優(yōu)勢(shì)明顯，可提高幾倍的效率。

C. Spot welding robot has obvious advantages in spot welding efficiency, which can improve the efficiency several times.

D.點(diǎn)焊機(jī)器人可以使用機(jī)器人的一些技術(shù)進(jìn)一步對(duì)焊接時(shí)序進(jìn)行控制，使焊接效率和焊接質(zhì)量進(jìn)一步提高。

D. Spot welding robot can use some robot technologies to further control the welding sequence, so as to further improve the welding efficiency and welding quality.
