[0018] In order to make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.

[0019] The utility model provides a kind of multifunctional bulk tray for SMT chip mounter, as shown in it, the bulk tray is equipped with several long, width, deep size different material pits, and material pit can be arranged side by side.As improvement, the bottom of material pit is equipped with inner material pit, and the length and width of inner material pit are less than material pit, and the axis of inner material pit can coincide with the axis of material pit, i.e. Figure 1

[0020] In specific implementation, the size of material pit and embedded inner material pit can be pulled out size gradient, and the length difference between material pit and inner material pit is 1.3-1.5mm, and the width difference between material pit and inner material pit is 0.8-1.1mm, i.e.

[0021] ​As a further improvement, the length, width and depth of the pits in the same row are all the same, and the length, width and depth of the inner pits in the same row are all the same. According to the use, the size of the pits in adjacent rows can be the same, and the size of the inner pits in adjacent rows can be the same, which is convenient for placing and picking up. In the embodiment, the length of the bulk material tray is 170mm, the width is 100mm, and the thickness is 5mm. The bulk material tray is provided with 20 rows and 20 columns of pits, the row spacing is 8mm, and the column spacing is 4mm.
