Definitions
- the present invention relates to a vibrator module for vibrating a carrier tape used to package electronic parts.
- parts in the compartments of a carrier tape and to wind the carrier tape on a reel for shipping.
- the parts are inspected immediately before being placed in the compartments of the carrier tape and are in some cases inspected after they are positioned within the compartments of the carrier tape.
- the present invention achieves the goal of properly positioning the parts in the carrier tape compartments by positioning a vibrator module near the carrier tape compartments. Before a part is inspected in a compartment, the vibrator module is turned on and transfers vibration to the carrier tape. The vibrations cause the part to settle into the proper position within the compartment. If the part is rejected by the in-tape inspection camera, a second vibrator module may be used to again vibrate the tape. The part may then be re-inspected to determine whether the first rejection was a false one.
- the vibrator module preferably includes a small electric motor having an eccentric weight mounted on its output shaft.
- a vibration transferring member is interconnected with the electric motor, and extends to a position near the carrier tape. The motor vibrates as the output shaft rotates, and the vibration is transferred through the vibration transferring member to the carrier tape, thereby causing the part to properly settle in the tape compartment.
- Fig. 1 is a side view of a taper apparatus embodying the present invention.
- Fig. 2 is a top view of the taper apparatus of Fig. 1.
- Fig. 3 is a schematic side cross-section view of a carrier tape in the taper apparatus.
- Fig. 4 is an enlarged view of a portion of Fig. 2, illustrating a vibrator module for use in the taper apparatus.
- Fig. 5 is a sectional view along line 5-5 of Fig. 4.
- Fig. 6 is a sectional view along line 6-6 of Fig. 4.
- Fig. 7 is a partially broken away schematic side view of an alternate construction of the vibrator module.
- Fig. 8 is a partial cross section view along line 8-8 of Fig. 7.
- FIGs. 1 and 2 illustrate a taper machine or taper apparatus 10 including a drive assembly 14 for advancing a carrier tape 18 through the taper apparatus 10.
- the apparatus 10 also includes a control panel 22 and the appropriate electronic control system for controlling the drive assembly 14 and other components of the apparatus 10.
- the apparatus 10 also includes a pair of guide rails or members 26 that guide the carrier tape 18 along the apparatus 10.
- the carrier tape 18 includes a top portion 30 and a plurality of compartments or pockets 34 recessed with respect to the top portion 30.
- the carrier tape 18 also has two flanges 36 (Fig. 6) that may extend over the top of the guide members 26 of the taper apparatus 10 such that the compartments 34 extend down between the guide members 26.
- the compartments 34 include tapered or angled side walls 38 and flat bottoms 42, and are thus designed to guide parts 46 into a relatively horizontal or flat orientation at the bottom of the compartments 34.
- the taper apparatus 10 includes a pick- and-place head 50 having a vacuum nozzle 54. The pick-and-place head 50 moves up and down to position one part 46 in each compartment 34.
- the tape 18 is then advanced along the taper apparatus 10, and a clear cover tape 55 is sealed to the flanges 36 with a sealing shoe 56.
- the parts 46 are then examined in-tape through the cover tape 55 with a robotic vision system including a camera 58.
- the camera 58 may be positioned to inspect the parts 46 prior to the cover tape 55 being applied.
- the robotic vision system is used to inspect leads 62 and other aspects of the parts 46.
- misalignment may occur when, for example, the pick-and-place head is not positioned directly above the tape compartment, the part is not centered on the pick- and-place head, or the part is not cleanly dropped into the compartment by the pick-and- place head.
- Misaligned parts may appear to have leads that are too long or too short to pass inspection, even though the leads are in fact of the proper length. For example, if the part is not settled, the camera 58 may see a partial reflection of the part off of the side walls 38 that distorts the true length of the leads 62.
- the apparatus 10 includes two vibrator modules 66, each including a small electric motor 70 having an output shaft 72, an eccentric weight 74 mounted to the output shaft 72, and a finger or a vibration transferring member which in the illustrated embodiment is a thin flexible strip of metal 78.
- the flexible strip 78 is attached in a cantilevered fashion at one end to a mounting boss 82 by a fastener 84 and projects away from the mounting boss 82.
- the mounting boss 82 is mounted to the taper apparatus 10 or one of the guide members 26 by fasteners 85.
- the motor 70 is mounted to the flexible strip 78 with bent fingers 86 (as illustrated in Fig. 5), fasteners, solder, brazing, welding, or any other suitable attachment means.
- the motor 70 is therefore supported in cantilevered fashion by the flexible strip 78.
- the flexible strip 78 is bent around the eccentric weight 74 and has a portion 90 positioned in a window 92 in one of the guide members 26.
- the portion 90 is thus directly alongside the compartment 34 that is currently under the pick-and-place head 50 or camera 58.
- the vibrations could be passed through the guide member 26, and the window 92 would not be needed.
- the first vibrator module 66 is positioned next to the carrier tape 18 under the pick-and-place head 50, and the second vibrator module 66 is positioned next to the carrier tape 18 under the camera 58 as seen in Figs. 1 and 2.
- the control system actuates the electric motor 70 of the first vibrator module 66.
- the rotating eccentric weight 74 creates vibrations which are passed by the flexible strip 78 to the compartment 34 currently under the pick-and-place head 50. If the part 46 is not properly positioned (i.e., in a flat orientation at the bottom of the compartment 34), the vibrations cause the part 46 to settle into a relatively flat orientation at the bottom 42 of the compartment 34 prior to inspection by the robotic vision system. If the part 46 is out of the compartment 34, the vibrations help to move the part 46 into the compartment 34. If the part 46 is properly positioned in the compartment 34, the part 46 will remain in the relatively flat orientation at the bottom of the compartment 34 during such vibration.
- a reject signal is sent to the controller.
- the controller then activates the second vibrator module 66 to vibrate the carrier tape 18 and compartment 34 under the camera 58.
- the part 46 is then re-inspected to see if the rejection was a false rejection due to the part 46 not being properly settled within the compartment 34.
- An operator of the apparatus 10 may program the control system with the number of re-inspections that should be performed before the part 46 is finally determined to be a bad part 46.
- the control system actuates the motor 70 before each re-inspection.
- the speed of the motor 70 it is preferable to adjust the speed of the motor 70 to adjust the amplitude and frequency of vibration produced to a suitable level for the tape 18 and parts 46 involved.
- the speed may be adjusted by regulating the amount of voltage entering the motor 70.
- a large voltage entering the motor 70 actuates the motor 70 at a high speed and produces large vibrations, while a small voltage entering the motor 70 actuates the motor at a low speed and produces small vibrations.
- Lower voltage and small vibrations are used for small compartments 34 and small parts 46, while high voltage and large vibrations are used for large compartments 34 and large parts 46.
- the flexible strip 78 When at rest, the flexible strip 78 preferably does not contact the adjacent compartment 34, but is very close to it. In operation, the flexible strip 78 bumps into the compartment 34 as the strip 78 vibrates, and thereby transfers the vibrations to the compartment 34. Alternatively, the flexible strip 78 may be in contact with the adjacent compartment 34 while at rest.
- the taper apparatus 10 may employ only one of the first and second vibrator modules 66 described above, and that use of even one of the vibrator modules 66 would still decrease the incidence of false rejections by the in-tape robotic vision system or station.
- the second vibrator module 66 may be positioned upstream of the camera 58 if a second robotic vision station is used in the taper apparatus 10, provided the second vibrator module 66 vibrates the tape prior to the second inspection in the event of a rejection by the first robotic vision station.
- the vibrator module may be used in a machine other than the illustrated taper machine.
- a vibrator module 94 includes a motor 98, an output shaft 102, an eccentric weight 106 and a vibration transferring member 110.
- the motor 98 is mounted to the taper apparatus 10 or the guide member 26 on a resilient mounting structure 114 (e.g., springs, rubber, etc.).
- An adjustable damper 118 is used to vary the amount of vibration caused by operation of the motor.
- the vibration transferring member 110 is mounted to the motor 98 and is used to transfer the vibration to the carrier tape 18.
- the vibrator module 66 may include vibration sources other than the illustrated motors 70, 98 and eccentric weights 74, 106, such as piezoelectric material operating under the influence of pulse current, a relay switch operating at a selected frequency, a voice coil operating at a selected frequency, or other suitable vibration sources.
- vibration sources other than the illustrated motors 70, 98 and eccentric weights 74, 106, such as piezoelectric material operating under the influence of pulse current, a relay switch operating at a selected frequency, a voice coil operating at a selected frequency, or other suitable vibration sources.
