摘要:
A method of preventing a nozzle or nozzles from dropping in a component mounting apparatus include gripping the nozzle structures with pivotal levers that are biased to a closed position. The pivotal levers are released after activation of the nozzles to permit appropriate movement for picking up, inspecting, orientating and locating electronic components on a substrate with the nozzles. During the operation of the mounting head, the levers are maintained in a release position against a biasing force and at the end of the operation, the biasing force can then cause the levers to close and support the nozzles in a gripping manner.
摘要:
A method of mounting an electronic component at a specified position of an object. The method includes applying a sealant beforehand in a first application process. The sealant is quickly, sufficiently and forcibly applied in the first application process simply by avoiding electrodes at the arrangement position, and tightly contacting the arranged electronic component and the object. Then, without obstructing successive bonding of electrodes of the electronic component and the object, the bonding of the electrodes is performed in the usual manner. A second application process is carried out by applying a sealant to the periphery of the electronic component in the same manner as in the convention method, which is sufficient to cause the sealant to flow to the sealant previously applied under the electronic component. The second application process can be accordingly conducted speedily and sufficiently. Air bubbles will not be trapped between the electronic component and the object, with the result that mounting failures due to breakage or corrosion of the electronic component because of the air bubbles can be reduced. Only a short period of time is required to apply the sealant even though it is applied twice, so that production time is shortened and production efficiency is improved.

An electronic component mounting method which employs a first air feed device connected to an air passage at one end part of a spline shaft, and a second air feed device connected to the air passage in the vicinity of the other end of the spline shaft. The first and second air feeds function to supply air to the air passage to return an interior thereof to atmospheric pressure. The time required to return the vacuum pressure in the air passage to atmospheric pressure can be shortened by the use of the two separate air feeds.

A receiving reel 10 comprises a receiving ratchet 11 and a detachable receiving cap 12 that is set in the receiving ratchet 11 and on which a covering tape 1c is wound, and is provided with contact members 13 and 14 that are provided on the area of engagement of the receiving cap 12 and the receiving ratchet 11. The contact members make contact in the direction of rotation and prevent the receiving cap 12 from coming loose. Mutually contacting concave and convex members 15 and 16 are provided on the contact surfaces along the direction of rotation of the contact members 13 and 14 to make it simple to detach the receiving cap 12 and to prevent it from coming loose and falling off.

A chip type electronic component includes a main body having opposite first and second end surfaces and a lower surface defining a first plane. First and second electrode portions are respectively connected to the first and second end surfaces of the main body. Each of the first and second electrode portions includes a lower surface. Each lower surface of the first and second electrode portions includes a first planar face extending adjacent the main body in a second plane which is parallel to the first plane defined by the main body, and a second planar face extending adjacent the first planar face in a third plane which extends upwardly at an angle relative the second plane away from the main body. Accordingly, upon mounting of the chip type electronic component to a planar circuit board, a space is provided between the second planar face of each of the first and second electrode portions for accommodating solder materials.

The present invention relates to method and apparatus for forming a thick film circuit by discharging a thick film paste from a paste discharging hole of a drawing nozzle and drawing a desired pattern on a substrate. The paste discharging hole has a substantially wide configuration and the drawing nozzle is rotated about its axis of rotation so that the longitudinal direction of the elongated cross-section of the paste discharging hole is substantially normal to the direction in which the drawing nozzle is moved with respect to the substrate.

An apparatus for automatically mounting electronic components on printed circuit boards has an insertion head which is adapted to rotate on an engaging shaft within a rotary bearing and be guided in the extent of rotation by means of a steel ball. Only the engaging shaft rotates and the position from which the components are supplied to the insertion head is stationary, the space needed for the inserting apparatus can be kept small. The bearing can be changed or the position of the bearing changed to change the insertion angle of the component relative to the printed circuit board, thus making possible various arrangements of the components on the circuit board.
