Description

Tray holding device, tray taking method, tray replenishing method and working machine

The invention provides a tray holding device that can smoothly take out trays, replenish trays and improve the yield rate of electronic components.

Nowadays, electronic components are stored in trays of different sizes according to different sizes or the requirements of the next process. For example, larger-sized ICs are stored in long trays, and smaller-sized ICs are stored in square trays. ; Taking a square tray as an example, its surrounding sides are flat, and a plurality of receiving grooves are recessed on the top surface to accommodate a plurality of smaller-sized ICs. Please refer to Figure 1. Taking the tray device in the feeding area using a square tray as an example, the tray device is arranged on the machine and mounted with a plurality of side plates 11. The plurality of side plates 11 surround a tray space 12, and a tray space 12 is formed. The bracket 13 can be displaced in the Z direction in the tray space 12 to carry a plurality of first trays 141 and second trays 142 that are stacked on top of each other and have electronic components. The material tray 141 reaches the top of the tray space 12 for taking out electronic components. When the electronic components of the first material tray 141 are taken out, a tray taker (not shown) is directly placed on the second material tray 142. Take out the empty first material tray 141 from the top surface so that the second material tray 142 can continue to supply materials.

However, due to the miniaturization and thinning of electronic components, and the second tray 142 with electronic components is stacked below the empty first tray 141, when the tray taker directly takes out the empty tray 142 from the top surface of the second tray 142, When the first material tray 141 is used, it is easy to cause the electronic components contained in the second material tray 142 to be vibrated by the first material tray 141. If the empty first material tray 141 is removed from the top surface of the second material tray 142 at a slow speed, the operation time will be increased and the production efficiency will be reduced.

Similarly, when the tray device in the receiving area receives the first tray with electronic components located above, if the second tray located below with electronic components is directly stacked on the first tray with electronic components , it is easy for the electronic components in the first tray to jump out and scatter due to the vibration of the stacked tray, thereby increasing the damage rate of the electronic components.
