CB15 Powered Lid Option



The model PWM32 Spin Controller has been upgraded and new product is now called model PWM50. We buy used equipment and factory re-furbish it at times, so the PWM32 may linger in our terminology and sales material for a considerable time. References to the PWM32 will be updated as soon as practical.

See the special page explaining the main differences in the two models.

Features

Front looking at Powered Lid

The CB15 Power Lid option utilizes a pneumatic actuator to open and close the lid. User actuated switches on the tabletop and/or a footswitch may be used to operate the lid. The PWM32 and MP100 controllers can automate the closing and opening of the lid, as a part of the programmed cycle.

The design permits the lid to begin closing rapidly to save time, then slow down to complete the closing very gently, to avoid jarring the system and potentially knocking particles loose. As the lid nears the closed position, the closing pressure is kept low to prevent possible injury to the operator, should their hand be in the closing lid's path. After the lid has closed unobstructed, the pressure is raised back to its maximum setting to provide a strong closure of the lid.

A safety feature of the design prevents the lid from operating (opening or closing) while the spinner motor is turning. The "OPEN" and "CLOSE" switches are, in effect, de-activated by a "speed does not equal 0" sensing circuit. The lid will not close if the accessory substrate lifter is in the "up" position. The Substrate Lifter will not lift a substrate, if the lid is in the closed position. An interlock circuit prevents the initiation of a spin cycle if the lid is not closed.

Manually operated CB15 lids require that the operator's hand pass over the work area when opening and closing the lid. Particles from the operator's hand, clothing, or the lid latch can fall on the work piece, thereby causing it to be a reject. The powered lid prevents this yield in reduction.

The operator may be working with substrates that require both hands for loading and unloading the spinner. The powered operation of the lid greatly facilitates loading and unloading of the system when both hands are full. The opening/closing of the powered lid can be automated (cycle start and end with the lid open) when the PWM32 or MP100 spinner controller is used. Otherwise, a footswitch can be utilized to free the hands

New requirements keep adding weight to the lids. Moving dispense arms, plastic safety shields, inhibited drying accessories, etc. make the manual lid more burdensome to manipulate, and may cause problems with keeping the manual lid open with the limited spring bias available. Excessive weight on the lid can create a necessity for the powered lid design.

These benefits are not only of importance to a heavily utilized machine (for convenience), but are also of equal importance with an infrequently used machine, if the most excellent end result is important for quality.
