榮仕杰為您詳細(xì)解釋點(diǎn)焊機(jī)器人在機(jī)械制造中的應(yīng)用實(shí)例！詳細(xì)視屏案例請(qǐng)點(diǎn)擊上方首頁(yè)觀看

點(diǎn)焊對(duì)所用的機(jī)器人的要求是不很高的。因?yàn)辄c(diǎn)焊只需點(diǎn)位控制，至于焊鉗在點(diǎn)與點(diǎn)之間的移動(dòng)軌跡沒有嚴(yán)格要求。這也是機(jī)器人最早只能用于點(diǎn)焊的原因。點(diǎn)焊用機(jī)器人不僅要有足夠的負(fù)載能力，而且在點(diǎn)與點(diǎn)之間移位時(shí)速度要快捷，動(dòng)作要平穩(wěn)，定位要準(zhǔn)確，以減少移位的時(shí)間，提機(jī)械臂。

高工作效率。點(diǎn)焊機(jī)器人需要有多大的負(fù)載能力，取決于所用的焊鉗形式。對(duì)于用與變壓器分離的焊鉗，30～45kg負(fù)載的機(jī)器人就足夠了。但是，這種焊鉗一方面由于二次電纜線長(zhǎng)，電能損耗大，也不利于機(jī)器人將焊鉗伸入工件內(nèi)部焊接；另一方面電纜線隨機(jī)器人運(yùn)動(dòng)而不停擺動(dòng)，電纜的損壞較快。因此，目前逐漸增多采用一體式焊鉗。這種焊鉗連同變壓器質(zhì)量在70kg左右。考慮到機(jī)器人要有足夠的負(fù)載能力，能以較大的加速度將焊鉗送到空間位置進(jìn)行焊接，一般都選用100～150kg負(fù)載的重型機(jī)器人。為了適應(yīng)連續(xù)點(diǎn)焊時(shí)焊鉗短距離快速移位的要求。新的重型機(jī)器人增加了可在0.3s內(nèi)完成50mm位移的功能。這對(duì)電機(jī)的性能，微機(jī)的運(yùn)算速度和算法都提出更高的要求。

The requirements for spot welding on the robot used are not very high. Because spot welding requires only point control, there is no strict requirement for the movement path of the welding tongs between points. This is also the reason why robots can only be used for spot welding. The spot welding robot not only needs to have sufficient load capacity, but also has a fast speed when moving between points, and the movement should be smooth and the positioning should be accurate to reduce the displacement time and lift the robot arm.

High work efficiency. How much load capacity a spot welding robot needs depends on the type of welding tongs used. For welding tongs separated from the transformer, a robot with a load of 30 to 45 kg is sufficient. However, on the one hand, the welding tongs have large electrical energy loss due to the length of the secondary cable, and are not conducive to the robot to extend the welding tongs into the workpiece. On the other hand, the cable runs without the robot moving, and the cable is damaged quickly. . Therefore, the use of integrated welding tongs is gradually increasing. This welding tongs together with the transformer quality is around 70kg. Considering that the robot has sufficient load capacity, the welding tongs can be sent to a space position for welding with a large acceleration, and a heavy-duty robot with a load of 100 to 150 kg is generally selected. In order to meet the requirements of short-distance rapid displacement of welding tongs during continuous spot welding. The new heavy-duty robot adds the ability to perform 50mm displacement in 0.3s. This puts higher requirements on the performance of the motor, the operation speed of the microcomputer and the algorithm.
