Problems solved by technology
[0007] Therefore, including the conveying device disclosed in the above-mentioned Patent Document 1, on the conveying device for electronic components that supports a plurality of suction jigs on the turntable, the following problem will occur: in order to make the height of the suction surface of the suction jigs assembled on the turntable constant, it is necessary to Each adsorption jig performs height adjustment work
[0009] However, even with this structure, it is impossible to alleviate the impact force applied to the electronic component when the suction jig impacts the electronic component at high speed.
[0010] The work of adjusting the height of the adsorption fixtures must be carried out one by one by the staff using manual tools, so the operation time is significantly increased
In addition, if the work is completed in a short time, the deviation in the height of the adsorption surface will increase

Embodiment Construction
[0034] Below, through Figure 1 to Figure 11 One embodiment of the conveying device for electronic components provided by the present invention will be described in detail.
[0035] figure 1 The conveying device 1 for electronic components shown uses a turntable 2 that is circular in plan view to transport electronic components 3 (refer to Figure 7 ) to a plurality of processing apparatuses 4 to 10 described later.
[0036] The turntable 2 has a disc shape, and is mounted on the base 11 via the driving device 12 with the axis pointing in the up-down direction. On the outer peripheral portion of the turntable 2 , a plurality of adsorption jigs 13 for adsorbing the electronic components 3 are arranged at equal intervals in the circumferential direction of the turntable 2 . In this embodiment, 30 (#1 to #30) suction jigs 13 are provided.
[0037] These adsorption jigs 13 are supported on the turntable 2 in a liftable manner, and are passed through the lifting device 14 descr...

Provided is an apparatus for conveying an electronic element, capable of adjusting the height of each absorbing clamp with high precision in a short time. The apparatus includes a rotating floor (2), a plurality of absorbing clamps (13), a pneumatic shuttle (18), an elevating device (14), and a control device (21) for controlling a descending amount of the absorbing clamps (13). The control device (21) comprises a height detection part (38) to detect a fiducial height of the absorbing clamps (13) by using a detection system different from that of the elevating device (14). The control device (21) comprises a correction part for correcting the descending amount of each absorbing clamp (13) so as to ensure the fiducial height of each absorbing clamp to be identical to the height of each absorbing clamp (13) detected by the elevating device (14).
Description
technical field [0001] The present invention relates to a conveying device for electronic components that absorbs and conveys electronic components with a suction jig. Background technique [0002] As such a conventional conveying device for electronic components, it is described in patent document 1, for example. The conveying device disclosed in Patent Document 1 includes: a turntable that supports a plurality of suction jigs to move up and down freely, and a lifting device for lifting and lowering the suction jigs. The turntable is circular in plan view, and is driven by a drive device to rotate intermittently around an axis in the up-down direction. [0003] The suction jigs are arranged at equal intervals in the circumferential direction on the outer peripheral portion of the turntable. Each adsorption jig penetrates the outer peripheral part of a turntable in the up-down direction. At the lower end of the adsorption jig, a suction surface for absorbing electronic co...
