SureShot Robot

Speed Up Production and Lower Cost with the SureShot Metal Dome Placement Robot

The SureShot™ is a high-speed automated system for the placement of metal domes. Its patented design dispenses metal domes from a cartridge, which is inserted into the Arrow™ placement head. The SureShot™ places a single dome on a target and then moves directly to the next target without having to reload. It can also dispense predetermined multiples for stacking domes in specified positions.

The SureShot is designed to place tactile metal domes on printed circuit boards, membrane switches, or flex circuits. Its compact tabletop design takes up minimal space. Four SureShot model sizes are available:

How it Works

The SureShot comes complete with easy-to-use software which can be loaded onto any personal computer. Coordinates for a specific project are programmed and uploaded to the SureShot unit. The operator simply chooses the project name from the built-in touchscreen monitor and initiates the build. The substrate is placed onto a 15.75” by 15.75” loading area which is accessible via a pull-out tray. After loading is finished, the completed work is removed, and a new substrate is installed to continue production. The SureShot Automated Placement machine comes complete with one Arrow dispensing head (8.5mm, 10mm, or 12mm), user software, and a user’s manual. Pre-loaded cartridges are sold separately.

Snaptron 4-leg domes can be packaged in cartridges for use with the SureShot dome placement machine and the Dart dome placement pen. Cartridges are easily loaded directly into the SureShot Arrow placement head or the Dart pen head for fast and accurate placement.

Depending on the size of the dome, cartridges are filled with 1,000 to 1,500 domes per cartridge. Custom quantities per cartridge can also be requested.

Automated Metal Dome Placement Machine

Innovative design concepts allowed Snaptron to incorporate a new delivery method with an upgraded motion system for faster, more efficient operation of a laborious job

Terry Persun, Contributing Writer — Design News, April 9, 2007  — View Article Online

Based on specific customer feedback, Snaptron Inc., of Windsor, CO, decided to tackle the problem of tactile metal dome placement in production situations. Prior to this time, the placement of metal domes to a substrate was performed by hand, which was time consuming and labor intensive. Using either tweezers or a vacuum pen to pick up a dome from a tray, a factory worker placed the dome into a pocket on the substrate.
