Problems solved by technology

However, in such a conveyor, there is a problem that since the time for the other conveying unit to discharge and supply the electronic components is longer than the time for one conveying unit to supply the electronic components for inspection, it is not possible to efficiently use the component inspection device. Inspection of electronic components performed
Therefore, the structure of the lifting mechanism becomes complicated in the lifting direction as a whole, and the increase in the size and weight of the conveying unit cannot be avoided. As a result, when conveying electronic components, the moving speed of the conveying unit will decrease, thereby reducing the conveying efficiency.
In addition, such a problem in the presence of such Figure 18 It is a common problem in the conveyor of the conveying unit as shown, regardless of the number of conveying units

no. 1 approach

[0040] Below, refer to Figure 1 to Figure 13 A first embodiment in which the conveyor and the parts inspection device of the present invention are embodied will be described. First, refer to figure 1 as well as figure 2 The structure of the conveyer and the parts inspection apparatus provided with this conveyer is demonstrated.

[0041] Conveyor and parts inspection device structure

[0042] Such as figure 1 As shown, on the base 11 of the conveyor 10 , a mounting surface 11 a on which various robots are mounted is provided as an upper surface, and most of the mounting surface 11 a is covered by a cover member 12 . The humidity and temperature of the transport space, which is a space surrounded by the cover member 12 and the mounting surface 11a, are maintained at predetermined values ​​by dry air supplied from the outside.

[0043] On the mounting surface 11 a of the base 11 , four conveyor belts extending in one direction are arranged in a direction perpendicular to...

no. 2 approach

[0115] Below, refer to Figure 14 ~ Figure 17 A second embodiment in which the conveyor and the component inspection device of the present invention are realized will be described. In addition, the basic configurations of the conveyor and the component inspection device of this embodiment are also the same as those of the first embodiment. However, in this embodiment, the number of the first elevating mechanisms, the number of the first elevating motors, the number of the gripping parts and their working methods are different from those of the first embodiment. Therefore, The following description will focus on this point.

[0116] Structure of the delivery unit

[0117] Such as Figure 14 As shown, a second elevating mechanism 71 is coupled to the conveyance guide 31 so as to be able to move back and forth along the conveyance guide 31 . At the lower end portion of the second elevating mechanism 71, a plate-shaped connecting portion extending along the mounting surface 11...

Abstract

The invention provides a handler and a part inspection apparatus. The handler includes at least one transport section which transports a transport target onto a base. The transport section includes a plurality of first elevating sections which respectively move up and down a plurality of gripping sections which grip the transport target, and a single second elevating section which moves up and down all the plurality of first elevating sections. In connection of the transport target to a connection destination, a part of the plurality of first elevating sections are driven to descend, and the remaining part thereof are driven to ascend.

Description

technical field [0001] The present invention relates to a conveyor for conveying objects to be conveyed, and a component inspection device including the conveyor. Background technique [0002] Generally, in a component inspection device that inspects electrical properties of electronic components, a conveyor that transports electronic components before and after inspection between a predetermined tray and an inspection socket is used. As such a conveyer, a conveyer including two conveyance units for inserting electronic components into inspection sockets after conveying electronic components from predetermined positions to inspection sockets is known, as described in Patent Document 1, for example. [0003] In the conveyor described in the aforementioned Patent Document 1, while one conveyor unit presses the electronic component against the socket for inspection and inspects it with the tester included in the component inspection device, the other conveyor unit inspects the ...
