摘要:
A method of controlling contact load in an apparatus for mounting electronic components on a substrate, in which a head is lowered at high speed to a slow down starting position where there is no risk that the electronic component makes contact with the substrate (S1), and from there the head is lowered at low speed until a predetermined target contact load is detected. The process of lowering the head at low speed includes the steps of moving down the head a predetermined distance (S3), measuring load after the step of moving down the head (S5), and determining whether the measured contact load has reached the target contact load (S9). The steps of moving down the head (S3) and measuring the load (S5) are repeated until the measured load reaches the target contact load. The actual contact load is precisely controlled to be close to a very small set level of target contact load. Accordingly, electronic components using low dielectric constant material are mounted without the risk of damage.

The production efficiency of electronic parts is improved by automatically examining the state of a defective nozzle, and efficiently and smoothly carrying out the maintenance of nozzles. An electronic part mounting method is practised by an electronic part mounting apparatus provided with an electronic part mounting means (7) having a plurality of nozzles (13) for use in clamping and mounting electronic parts (14), an image pickup means (15) for imaging an electronic part (14) clamped by a nozzle (13), and a recognition control means (16) adapted to analyse the image of the electronic part (14) and examine the clamped state of the electronic part (14). When a nozzle (13), which has made clamping errors a predetermined number of times, is judged to be a defective nozzle, the free end surface thereof is imaged by the image pickup means (15), the image is analyzed by the recognition control means (16), whereby the free end surface of the nozzle (13) is examined.
摘要:
In electronic component mounting method and apparatus, an electronic component is taken out from an electronic component feed position, a posture of the taken-out component is detected, and the component is mounted on a board based on a detected result. The method includes acquiring image data of the component taken-out from the feed position by a camera, processing acquired image data with a plurality of algorithms for detecting postures of components, and detecting a posture of the taken-out component.

A component feeding device (20) located on the rear side of an apparatus body (1) includes a component feed table circulation path within a vertical plane, and a plurality of movers (31, 32) as well as table lifting mechanisms (22, 27) for moving independently a plurality of component feed tables (21) placed within the circulation path. By this arrangement, the component feeding device (20) is prevented from upsizing even if the number of components is increased, and besides a speedup of component feed is achieved. By providing a component exchanging device (44) for pulling out a component feed table (21) from a takeout position of the circulation path and transferring it up to an exchange position on the front side of the apparatus body (1), it is enabled to carry out the exchange of the component feed tables (21) on the front side of the apparatus body (1).

A pharmaceutical composition for the treatment of interleukin-6 (IL-6) related diseases, comprising an interleukin-6 antagonist (IL-6 antagonist) and immunosuppressants. The IL-6 antagonist is preferably an antibody to an interleukin-6 receptor (IL-6R).
摘要:
The component handling tool (14) is moved linearly up and down on a moving mechanism (11) by feedback control of a linear motor (16) for performing pickup and mounting actions of components (3). The linear motor is controlled to effect a downward movement of the component handling tool for bringing the component handling tool or the component held thereby closer to the component or to a mounting object, and upon detecting changes in control information when contact is made with the component or the mounting object, control of the linear motor is switched to a pressing operation, whereby the holding or mounting of the component in a prescribed pressed condition is accomplished.
摘要:
An efficient parts mounting method and a parts mounter to avoid wasteful operation and time when mounting parts on a circuit board. For this parts mounter, a nozzle existence checking sensor (7) is installed at a parts mounting means (1) loaded with a suction nozzle (2). When a user carries the circuit board (3) into a circuit board supporting means (5), the nozzle existence checking sensor (7) can detect the present nozzle charge condition of the parts mounting means (1) while the parts mounting means (1) shifts to a parts disposal box (6). Moreover, unless the parts mounting means (1) is not loaded with a suction nozzle (2) required for the next parts mounting in the middle of production, the existence of the nozzle is checked in the middle of shifting to a nozzle exchanging means (8).
摘要:
In component mounting for executing component feed operation and component holding and pickup operation, a recipe for the component holding and pickup operation that is an operation program for executing the component holding and pickup operation is received in a head unit (4), and the component holding and pickup operation is executed on the basis of the recipe. In addition, a timing signal based on the execution is transmitted to a component feed unit (6), the recipe for the component feed operation for executing the component feed operation is received in the component feed unit, and the component feed operation is completed on the basis of the recipe and the timing signal transmitted from the head unit.
