Apparatus and method for mounting components on a substrate
The invention relates to an apparatus and a method for mounting components on a substrate. The apparatus comprises a bond head with a component gripper, a first drive system for moving a carrier over relatively long distances, a second drive system which is attached to the carrier for moving the bond head back and forth between a nominal working position and a stand-by position, a drive attached to the bond head for rotating the component gripper or a rotary drive for rotating the substrate about an axis, at least one substrate camera attached to the carrier and at least one component camera. Either the second drive system is also designed to perform high-precision correction movements with the bond head, or a third drive system is provided to perform high-precision correction movements with the substrate. At least one reference mark is attached to the bond head or the component gripper.
Addressing misalignment of LEDs on a printed circuit board
LEDs for an illumination system may be mounted on a PCB. The PCB may be provided with alignment features such as oversized holes for connection to a support surface. Using optical sensing of the position of the mounted LEDs, the space made available by the alignment features may be reduced and aligned to create modified alignment features. The modified alignment features may be created by adding a modifying component and aligned based on the sensed positions of the mounted LEDs. The positioning of the modifying component may offset misalignment of the LEDs with the PCB. An opening in the modified alignment feature may receive a bolt or alignment pin for connection to the support surface. The support surface may be aligned with the secondary optics, resulting in the LEDs being aligned with the secondary optics irrespective of misalignment of the LEDs with respect to the PCB.
PICK AND PLACE SYSTEM AND METHODS FOR USE
A pick and place system and methods of use are presented. The pick and place system comprises a backing plate, a porous facesheet, and a flow generator. The backing plate is configured to direct air flow within the pick and place system. The porous facesheet is secured to the backing plate. The flow generator is configured to provide an air flow between the backing plate and the porous facesheet.
Component mounting device
A component mounting device includes a heater unit which heats along a range which is narrower than a movement range of a head and which is a partial length of a board, in which the head is controlled to mount components onto the board using a heating range of the heater as a mounting range, the board is conveyed to shift the mounting range every time mounting of components in the mounting range is completed such that an unmounted range in which components are not mounted on the board becomes the mounting range, and components are mounted in a new mounting range.
Machine for performing specified work to a printed circuit board
A dedicated correction value related to the mounting position of an upper surface recognition component with a characteristic section on an upper surface thereof is memorized in correction value folder 43a of an HDD, and when performing mounting work of mounting the upper surface recognition component on a board, a position deviation amount of the characteristic section is acquired based on an image of the upper surface of the upper surface recognition component captured by a mark camera, and the component is mounted at the mounting position based on the acquired position deviation amount and the dedicated correction value. Accordingly, it is possible to mount the specific component at a corrected mounting position such that the position of the characteristic section is appropriate, thereby improving mounting accuracy for the upper surface recognition component.
METHOD FOR INSPECTING MOUNTING STATE OF COMPONENT, PRINTED CIRCUIT BOARD INSPECTION APPARATUS, AND COMPUTER READABLE RECORDING MEDIUM
A printed circuit board inspection apparatus can inspect a mounting state of a component by generating depth information on the component by using a pattern of light reflected from the component mounted on a printed circuit board received by an image sensor, generating two-dimensional image data for the component by using at least one of light of a first wavelength, light of a second wavelength, light of a third wavelength, and light of a fourth wavelength reflected from the component received by a first image sensor, inputting the depth information and the two-dimensional image data for the component into a machine learning-based model, obtaining depth information with reduced noise from the machine learning-based model, and using the noise-reduced information.
Substrate working machine
Movable section of a cut and clinch unit includes exchange section in which is formed second insertion hole for cutting and bending a lead, and main body section to which exchange section is removably attached. An opening position of the second insertion hole is calculated as an attachment position of the exchange section on the main body section based on image data. It is determined whether a difference between the calculated opening position and a standard position of the second insertion hole that is set in advance exceeds a threshold value. If the difference between the calculated opening position and the standard position exceeds the threshold value, calibration is performed based on the assumption that the exchange section has been exchanged.

Component mounting device
A component mounting device includes a mounting head that mounts a component at a mounting position on a substrate, an imaging unit capable of imaging the mounting position from a plurality of fields of view, imaging directions of which are different from each other, and a controller that selects a success or failure determination field of view used for success or failure determination of whether or not the component has been mounted at the mounting position from the plurality of fields of view according to a state of a shield around the mounting position.
COMPONENT MOUNTING DEVICE, METHOD OF CAPTURING IMAGE, AND METHOD OF DETERMINING MOUNTING SEQUENCE
A component mounting device for mounting a component on a substrate includes a head unit, a driver to move the head unit on a stage, and a controller. The head unit includes a mounting head to hold the component and a stereo camera to capture a three-dimensional image of an object. The controller performs image capturing, calculating and mounting processes. The image capturing captures an image of a relevant area including a mounting point on the substrate by the stereo cameras before the component reaches the mounting point. The calculating calculates a correction amount with respect to X, Y and Z axes directions based on three-dimensional information on the relevant area with respect to the directions obtained in the image capturing process to mount the component on lands corresponding to the mounting point. The mounting includes correcting the mounting point based on the correction amount and mounting the component.
