Dual Servo Spin Welder User’s Manual

Constant Torque Option

This option sets the welder to function in “Melt-Match” mode, in which the press vertical speed is continuously adjusted to match the rate of plastic melt at the joint. This is achieved by measuring the spin torque and changing the verical speed on-the-fly based on this measurement. The vertical speed is inversely proportional to the spin torque: the lower the spin torque, the higher the vertical speed, and vice versa.

To enable this option, press the Constant Torque button and then the Enable box on the screen shown in Figure 5-19. The relationship between the spin torque and vertical speed is illustrated in Figure 5-20. The welder will adjust vertical speed for a measured spin torque along the lines shown. The Torque Target is the desired spin torque, which is entered into the Torque (% of max..) field on the screen. The Max. Torque value is 5% larger than the Target Torque. If the measured torque exceeds the Max. Torque, the vertical speed will be 0 until the torque drops below the maximum. The Max. Speed is the maximum allowable vertical speed, which will occur if the measured torque is 0. This value is entered in the VERT.. Max (mm/s) field on the Weld Parameters screen (in the WELD tab). The Timeout (s) field specifies the maximum weld time before the machine aborts the cycle and reports an error.

The actual spin torque profile achieved during the weld will depend on the Torque (% of max..) and the VERT.. Max (mm/s) settings for a particular application. For example, if the actual spin torque is consistently below the specified target, the VERT.. Max (mm/s) will need to be increased to cause the welder to move down faster, causing a rise in the spin torque.

POST-WELD Setup

The POST-WELDsetup is the right tab in the SETUP menu and is shown in Figure 5-21. The screen is divided into two sections: Hold Setup and Part Tests.

Hold Setup

The Hold Setup button is used to enter parameters related to the Hold phase of the weld cycle. During this phase, the molten plastic cools and solidifies, beginning when the spin tool stops. Pressing the Hold Setup button
