Abstract:
The present invention provides a system and method that secures feeders mechanisms to SMTs. This system includes pneumatic or hydraulically driven cylinder(s) that positions a clamping plate to secure feeder mechanism to the feeder plate thus preventing relative motion between the feeder mechanism and the SMT.
Abstract:
A method for calibrating at least one device (2) that comprises a camera, in which an object (3, 10) having at least one reference element (4, 11, 12, 13, 14) is brought into the image area of the camera. A first position of the reference element (4, 11, 12, 13, 14) relative to the device (2) is determined from an image (5, 6, 8, 9, 15, 16) made by the camera. Then a displacement relative to the device (2) is imposed on the object (3, 10). A second position of the reference element (4, 11, 12, 13, 14) relative to the device (2) is determined from a second image made by the camera (5, 6, 8, 9, 15, 16). A real displacement of the object (3, 10)(3) relative to the device (2) is determined from the first and second relative positions, which real displacement is compared with the imposed displacement.
Abstract:
A method of and an apparatus are described for placement of a component (2) at a required position on a substrate (3) by means of a placement device (1). The component is transported to an intermediate position abovethe required position and a position difference between the intermediate position of the component and the required position is determined by means of a camera (12) and a processor. Then the component is transported to the required position on the substrate, making use of the difference position. The camera, which is arranged at the sideof the component opposite the component's side facing the substrate, takes an image of at least the portion of the substrate comprising the required position as well as of the placement device (1; 5, 6, 7).
Abstract:
Component placement apparatus (1, 21) comprising a storage device (2) for storing components, means (5, 25, 71, 81, 91) for transporting a component from the storage device (2) to a transfer device (6, 26) comprising at least one component pickup position (11), and a component pick and place device (7) for picking up a component from the pickup position and placing the component on a desired location on a substrate (8) positioned on a substrate support. The transfer device (6, 26) is movable between a position relatively close to the stationary storage device (2) and a variable desired position above the substrate support relatively close to the movable pick and place device whilst the means (5, 25, 71, 81, 91) for transporting a component from the storing device to the transfer device (6, 26) comprise guiding means for guiding a tape (4) comprising components from reel (3) located in the storage device (2) ito the component pickup position (11) on the transfer device (6, 26).
Abstract:
The contrast between solder balls and substrate of a Ball Grid Array (BGA) as visualized by a camera of a computer vision system is improved sufficiently to enable reliable recognition in the poor contrast situation when the balls are silver colored and the substrate background is white or light colored by illuminating the BGA with polarized light, and the camera viewing the light reflected from the BGA via a polarization filter oriented to not pass light reflected from the solder balls but to pass light reflected from the substrate.
Abstract:
Component placement apparatus (1, 31) comprising a storage device (2, 32) for storing components, means (3, 33) for transporting a component from the storage device (2, 32) to a transfer device (4, 5, 37) comprising at least one component pickup position, and a component pick and place device (6, 36) for picking up a component from the pickup position and placing the component on a desired location on a substrate (7) positioned on a substrate support. The transfer device (4, 5, 37) is movable between a position relatively close to the stationary storage device (2, 32) and a variable desired position above the substrate support relatively close to the movable pick and place device.
Abstract:
A method of placing at least one component (25) on at least one substrate (24), a component (25) being picked up by means of at least a placement machine (2) and placed on a desired position on the substrate (24). After the component (25) has been placed on the substrate (24), an image of the component (25) placed on the substrate (24) is made by a camera (5, 23), a difference between the real position of the component (25) on the substrate (24) and the desired position of the component (25) on the substrate (24) being established on account of the image. The positioning of a next component (25) to be placed is adapted on account of the difference found.
Abstract:
The present invention provides a non-contact drive belt tension monitoring apparatus for measuring drive belt tension on a drive belt vibrating in response to a stimulus. A coherent light source, associated with the drive belt, generates coherent light which is reflected by a determined region of the drive as reflected coherent light. A light receiver receives reflected coherent light containing vibration information. Attached circuitry processes the output of the light receiver to generate a drive belt tension measurement.
Abstract:
The invention relates to a device for displacing PCBs (10) through a device wherein components can be mounted on the PCBs. The device comprises two beams (2) having regularly spaced teeth (3) for supporting the PCBs at opposite edges. Said beams can be moved up and down and displaced backwards and forwards in the longitudinal direction. Furthermore, two fixed supports (5) having teeth (6) are provided. The arrangement is such that to lift a PCB (10) resting on the supports (5), the teeth (3) of the beams (2) can be moved upwards in the spaces between the teeth (6) on the support members (5). For displacing the beams (2) in their longitudinal direction, the teeth (3) of the beams (2) can be arranged in a position below and a position above the teeth (6) of the support members (5).
Abstract:
Component placement device (1) provided with at least two component pick and place units (13) connected to a movable frame (2) and at least two component feeding devices (7), which component placement device (1) is suitable for simultaneously picking up components supplied by means of the component feeding devices (7) by means of the component pick and place unit (13). At least one component pick and place unit (13) can be moved relative to the frame (2), which permits adjustment of the positions of the component pick and place units (13) relative to one another.
