Electronic component feeder and electronic component feeding method

Abstract

The invention provides a forward side adjuster (18) for adjusting the support position of a pallet loaded in a bin (4) on the forward side in the pallet feeding direction (A); an adjustment member (24), movable in said direction, for adjusting the support position of the pallet adjusted by the forward side adjustment member on the rearward side in said direction; and a horizontal attitude adjustment member (26), which can Provided between the pallets for adjusting the supporting posture of the pallets so as to maintain a substantially horizontal supporting posture of the pallets supported by the pair of supports with the arrangement.

Description

technical field [0001] The present invention relates to an electronic component feeder and an electronic component supply method for supplying a plurality of electronic components aligned in a line on a component supply tray to mount the components on a board. Background technique [0002] Conventionally, various structures of such electronic component feeders are known. In this type of electronic component feeder, multiple pallets are loaded, stacked in layers (or stacked in rows) in a magazine, where on said pallets are placed components often used for electronic component-to-electronic component mounting A component supply tray (hereinafter referred to as a tray) of the supply system of the equipment. The electronic component feeder utilizing such a conventional magazine is configured to move the magazine up and down in the vertical direction or in the direction in which the pallets are stacked by the lifting unit, place the selected pallet in the pallet unloading positi...

AI Technical Summary

Problems solved by technology

Since the pallet generally does not have a symmetrical structure in the length direction, the pallet placed upside down cannot perform its function, and this causes a problem that the electronic component feeder cannot be properly handled, possibly causing damage to the constituent parts of the feeder and the dispersion and damage of electronic components arranged on the tray, etc.

[0006] However, the above-mentioned structure has a problem in that although it is possible to prevent the pallet from being loaded in the direction opposite to the length direction, when the pallet is correctly loaded in the length direction, it can be detected even if the pallet is loaded obliquely in the silo ( or to prevent) misplaced

In this case, it is difficult for an operator concentrating on the electronic components to notice the inclined pallet insertion

In addition, there is a problem that since the number of pallets to be loaded into the bin increases, that is, the number of pallets decreases according to the size and thickness of electronic components to be mounted, and the number of pallets further increases according to the variety of types of electronic components, the operator makes mistakes. Increased likelihood of what happens when pallets are placed at an angle

Therefore, in the case where the suction nozzle disadvantageously sucks and holds, for example, a portion of the electronic component 551 that is not set on the component supply tray 552, when each of the electronic components 551 set on the component supply tray 552 is sucked and held by the suction nozzle And when picking up, there is such a problem that the component supply tray 552 itself is unfavorably lifted from the tray placement surface 554 in accordance with the rise of the suction nozzle, which may cause the displacement of the setting position of other electronic components 551 set on the component supply tray 552 and electronic components. Components 551 leap-up from component supply tray 552

Therefore, there is such a problem that there is a high possibility that the component supply tray 552 is disadvantageously sucked by the suction force of the suction nozzle when no electronic component 551 exists in the height position where the electronic component 551 is sucked and held by the lower suction nozzle; and The component supply tray 552 is likely to be lifted later, etc.

[0018] In addition, the occurrence of erroneous suction of the suction nozzles to the component supply tray 552 as described above is sometimes caused by erroneous input of component data or the like of the electronic components 551 to the control unit that performs the operation control of the suction nozzles.

[0019] As described above, there is a problem that effective electronic component supply cannot be achieved when jumping of the electronic component 551 or the like is caused by incorrect suction of the suction nozzle to the component supply tray, and this significantly reduces the electronic component provided with the suction nozzle. Operating speed of component mounting equipment so that efficient component mounting cannot be performed
