[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0035] The application will be described in further detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, and not to limit the utility model. In addition, it should be noted that, in order to facilitate the description, only the parts related to the utility model are shown in the drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict.

[0036] The utility model provides with the chip tray feeding device who has the material detection mechanism, as shown, including the chip tray cabin mechanism 1 for the automatic chip tray 100, the chip tray support mechanism 2 for supporting chip tray 100, the material detection mechanism 3 in the top of chip tray support mechanism 2, the tray turnover mechanism 4 for picking up the chip tray cabin mechanism and transferring the chip tray to the chip tray support mechanism on the tray. Figures 1 to 6

[0037] The chip tray cabin mechanism 1 includes the chip tray feeding end 10.

[0038] The chip tray support mechanism 2 includes a support body 21 and a positioning part 22 arranged on the support body 21 for positioning the chip tray.

[0039] The material detection mechanism 3 includes an image acquisition part 30 for detecting the chip tray.

[0040] The tray turnover mechanism 4 includes a tray pickup part 40 for linear displacement between the chip tray feeding end 10 and the support body 21, and the tray pickup part has lifting displacement.

[0041] Specific implementation process and principle explanation:

[0042] The chip tray cabin mechanism 1 supplies the chip tray, which is discharged by the chip tray feeding end 10. The tray turnover mechanism 4 picks up the chip tray on the chip tray feeding end 10 and transfers it to the support body 21 through linear displacement and lifting displacement. The chip tray is positioned by the positioning part 22, and the image acquisition part 30 detects the number of chips on the current chip tray to obtain the information of the empty slot on it.

[0043] ​In one embodiment, the supporting body 21 comprises two spaced-apart supporting rails 211, and each of the opposite walls of the two supporting rails is provided with a supporting groove 212.

[0044] The positioning part 22 comprises a positioning body 221 provided on each of the supporting rails and having linear displacement, and the chip tray is provided with a positioning matching part 222 corresponding to the positioning body.

[0045] Specifically, the two ends of the chip tray are supported by the supporting grooves 212 on the two supporting rails 211, and the spacing between the two supporting rails facilitates the avoidance of the tray pickup part 40.

[0046] The positioning body 221 is generally a wedge-shaped top block, and the positioning matching part is a positioning groove body corresponding to the wedge-shaped top block, which realizes positioning matching through the extension and retraction displacement, and ensures the reliable position.

[0047] In one embodiment, the supporting body 21 comprises a detection station 5 and a discharge station 6 spaced apart along the rail direction of the supporting rails, the lack-of-material detection mechanism 3 is arranged on the top of the detection station, the detection station and the discharge station are respectively provided with a positioning part, and the tray pickup part comprises a first turnover displacement for turnover between the chip tray supply end and the detection station and a second turnover displacement for turnover between the detection station and the discharge station.

[0048] Specifically, the implementation process and principle are described as follows:

[0049] Generally, the lack-of-material detection mechanism 3 has a certain depth of field, so the distance between the detection mechanism and the detection station is small. When the mechanism is automatically matched with the rear-end equipment, the specification of the rear-end turnover arm is limited, which easily causes collision risk. In view of this situation, the detection station and the discharge station are designed. The detection is performed on the detection station, and the transfer is performed on the discharge station to realize the turnover matching with the rear-end mechanical arm. Such operation is safer and more reliable.

[0050] Specifically, the tray pickup part first picks up the chip tray to the detection station for detection, and then picks up and transfers to the discharge station after the detection is completed. Such operation is smooth and meets the requirement of rear-end automatic turnover avoidance matching. At the same time, the discharge station can realize buffering, and only when the tray is taken away, the next cycle of tray taking operation is performed.

[0051] In one embodiment, the two supporting rails have relative adjustment displacement.

[0052] Such operation meets the specification adjustment and matching requirements of various chip trays.

[0053] Embodiment one

[0054] The chip tray bin mechanism 1 comprises a bin main body 11 and a feeding lifting driving source 12 for driving the bin main body to lift and displace, a plurality of chip trays are vertically and alternately arranged in the bin main body, and a feeding end of the chip tray is arranged on a side wall of the bin main body facing the chip tray supporting mechanism.

[0055] This embodiment adopts the side wall feeding mode.

[0056] Therefore, in order to match the feeding mode, the tray pickup part is designed as a clamping gripper.

[0057] The clamping type feeding can be realized.

[0058] Embodiment two

[0059] The chip tray bin mechanism comprises a stacking feeding bin for stacking a plurality of chip trays, a lifting driving source arranged at the bottom of the stacking feeding bin for lifting the chip tray, and a feeding end of the chip tray arranged at the top of the stacking feeding bin.

[0060] This embodiment adopts the top end feeding mode.

[0061] Therefore, in order to match the feeding mode, the tray pickup part is designed as a negative pressure pickup end.

[0062] Whether it is side wall feeding or top end feeding, only the mechanism for feeding the chip tray needs to be met, and the pickup end design matched according to different discharge ends is also within the protection scope of the case.

[0063] In a specific embodiment, an identification code is arranged on the chip tray, and the lack of material detection mechanism comprises an identification detection part 7 for identifying the identification code.

[0064] The identification detection part 7 meets the identification requirement of the identification code of the chip tray, so that the rear-end lack of material information can be associated and matched with the identification code, and the operation is more reliable and efficient.

[0065] From the above description, it can be found that the chip tray feeding lack of material detection requirement is met, the detection efficiency of the rear-end detection equipment is indirectly improved, and unnecessary energy consumption is reduced. By providing the design of the detection station and the discharge station, the avoidance space is provided, the rear-end automatic turnover cooperation is facilitated. Various specifications of chip trays can be compatible and carried, and the accurate positioning requirement of the chip tray is met. The operation is smooth and efficient, the feeding material operation is stable and reliable.
