[0026] Reference will now be made in detail to embodiments of the present disclosure, one or more examples of which are set forth herein below. Each embodiment and example is provided by explaining the apparatus, composition and materials of the present disclosure, rather than limiting. On the contrary, the following description provides a convenient illustration of an exemplary embodiment for implementing the present disclosure. In fact, it will be clear to those skilled in the art that various modifications and variations can be made in the teachings of the present disclosure without departing from the scope or spirit of the present disclosure. For example, a feature shown or described as a part of an embodiment can be used in conjunction with another embodiment to produce yet another embodiment. It is expected that the present disclosure covers such modifications and variations within the scope of the appended claims and their equivalents. Other objects, features and aspects of the present disclosure are disclosed in or clear from the following detailed description. It will be understood by those of ordinary skill in the art that this discussion is only a description of exemplary embodiments and is not intended to limit the wider aspects of the present disclosure.

[0027] like Figure 1-Figure 4 As shown, the present invention discloses a chip tray flipping and feeding device, comprising a flipping body 1, on which a rotating mechanism for driving the flipping body 1 to rotate and a limiting mechanism for limiting and fixing a tray 2 of the closing tray so as to rotate with the flipping body 1 are arranged, the limiting mechanism is provided with a knocking component 3 for driving the tray to vibrate and transfer the chip between the two trays after flipping; the limiting mechanism comprises an upper opening and closing component and a lower opening and closing component respectively arranged on the upper and lower surfaces of the flipping body 1, the tray 2 is allowed to enter by opening and closing the upper opening and closing component and the lower opening and closing component, and the tray 2 is limited and fixed after entering, the tray is formed by two trays closing together, and a chip is arranged in the lower tray, after completing the defect detection on the chip surface, the chip needs to be transferred to another tray by flipping to realize the turning over of the chip so as to perform defect detection on the other side; the flipping and feeding device of the present invention is formally based on this use demand, and realizes the flipping of the tray and the transfer of the chip while keeping the closing state intact.

[0028] The upper opening and closing assembly and the lower opening and closing assembly of the present invention limit the upper and lower positions of the material tray by opening and closing. When the material tray enters the flip body 1, it will not be affected, and the force acting on the material tray is only on the upper and lower surfaces of the material tray, which will not affect the closed disc body of the material tray, so that the grooves of the material tray can remain corresponding.

[0029] like Figure 2 and Figure 3 As shown, the upper opening and closing assembly of the present invention includes an upper opening and closing cylinder 4, an upper opening and closing plate group, and an upper guide rail 5 arranged on the surface of the flip body 1 to guide the movement of the upper opening and closing plate group. The upper opening and closing plate group is slidably connected to the flip body 1 through the upper guide rail 5, and the upper opening and closing cylinder 4 drives the two upper opening and closing plates 6 of the corresponding upper opening and closing plate group to slide for spacing adjustment; the lower opening and closing assembly has the same structure as the upper opening and closing assembly, including a lower opening and closing cylinder 7, a lower opening and closing plate group and a lower guide rail 8, and the two lower opening and closing plates 9 of the lower opening and closing plate group are both provided with a floating plate group for fixing the material tray 2, and the floating plate group is slidably connected to the lower opening and closing plate group along an opening and closing direction perpendicular to the lower opening and closing assembly, and a lifting mechanism is provided on the flip body 1 for driving the floating plate group to move up and down to cooperate with the upper opening and closing assembly to clamp and fix the material tray. If the lower surface of the tray is limited and fixed directly by the lower opening and closing assembly, on the one hand, high assembly accuracy is required, and on the other hand, it is easily affected by the closed state of the tray, and collisions are likely to occur during the opening and closing process, causing damage to the equipment. For this reason, the present invention adds a floating plate group, and the position of the lower opening and closing plate group is at a certain distance relative to the lower surface of the tray, so that opening and closing can be achieved smoothly without worrying about collisions between structures.

[0030] Specifically, a guide shaft 11 cooperating with the corresponding lower opening and closing plate 9 is provided on the floating plate 10 of the floating plate group of the present invention, and the end of the guide shaft 11 is inserted into the lower opening and closing plate 9, and the guide shaft 11 is located between the lower opening and closing plate 9 and the plate surface of the floating plate 10, and a spring is sleeved on the shaft body; the floating plate 10 is driven by the guide shaft 11 to synchronously open and close when the lower opening and closing plate 9 moves, and the floating plate 10 is provided with a clamping plate 12 for clamping the material tray in the plate surface area close to the inner side of the lower opening and closing plate 9, and the clamping plate 12 is perpendicular to the plate surface of the floating plate 10, and when the floating plate 10 moves along the direction of the guide shaft 11, the clamping plate 12 moves synchronously with the floating plate 10.

[0031] In order not to affect the opening and closing movement of the floating plate group, the lifting mechanism Figure 4 As shown, the lifting mechanism of the present invention includes a lifting cylinder 13 and a driving block 14 fixed to the lifting cylinder 13. The driving block 14 is located below the floating plate 10 and the position of the driving block 14 covers the opening and closing movement range of the floating plate 10 along with the lower opening and closing component. The lifting cylinder 13 lifts the floating plate 10 through the driving block to clamp the material tray.

[0032] The knocking component 3 of the present invention can be directly implemented by a vibration motor to knock on the material tray so that the chip can be separated from the groove of the original material tray; in order to improve the separation effect and reduce the damage caused by the knocking of the material tray, the driving end of the knocking component of the present invention is located on the side where the floating plate 10 is located. After the flipping is completed, the knocking component 3 knocks the material tray 2 through the floating plate 10 to unload the material, so that the chip is separated from the groove of the current material tray 2 and enters the zero-one material tray below. The floating plate can increase the contact area of ​​the knocking to ensure that each part is evenly stressed. At the same time, a floating design with a spring can reduce damage to the material tray.

[0033] The rotating mechanism of the present invention includes a rotating shaft 15 fixed to the flip body 1 and a rotating wheel 16 fixed on the rotating shaft 15. The rotating wheel 16 is connected to the corresponding rotating power source, and then drives the flip body 1 to rotate through the rotating shaft 15. The rotating wheel 16 can be driven by gears, synchronous belts or chains according to the form of the rotating wheel used.

[0034] The present invention also discloses a method for using the chip tray flipping and feeding device based on the above-mentioned chip tray, wherein the chip tray to be flipped is transported to the bottom of the flipping body, and is driven up by a lifting device to enter the flipping body, and the upper opening and closing assembly and the lower opening and closing assembly will limit the tray entering the flipping body, and then the rotating mechanism will drive the flipping body and the tray to rotate for flipping. After flipping, the chips in the tray are transferred to the tray below under the action of gravity, thereby realizing batch flipping of chips, and the vibration of the tray is caused by the knocking assembly so that the chips can be smoothly transferred between the trays.

[0035] The process of limiting the position of the material tray by using a limiting mechanism in the present invention includes: the material tray moves upward under the action of a set lifting device, the lower opening and closing component remains in an open state, the upper opening and closing plate of the upper opening and closing component is closed under the action of the upper opening and closing cylinder, and the upper surface of the material tray of the closing plate is blocked and limited by the upper opening and closing plate. After the material tray rises into place, the lower opening and closing component is closed, and the lower opening and closing plate moves to the bottom of the material tray; the material tray is limited in the flipping body by the upper opening and closing component and the lower opening and closing component, and then the floating plate is driven to move up by the lifting cylinder so that the clamping plate on the floating plate contacts the lower surface of the material tray, and the material tray is stably fixed in the flipping body, and then the material tray is driven to flip by the flipping body.

[0036] After the flipping is completed, the lifting cylinder releases the limit on the floating plate. Under the action of the spring, the floating plate can move up and down along the guide shaft. The floating plate is vibrated by the knocking component. The floating plate knocks the material tray according to the vibration frequency to assist the transfer of chips in the material tray.

[0037] To facilitate the explanation of the process of transferring chips by flipping the material tray, the present invention divides the material tray before rotation into an upper material tray and a lower material tray, and the chip is in the lower material tray. After the trays are closed, the lower material tray and the upper material tray are sent into the flipping body 1, and the upper surface of the upper material tray contacts the upper opening and closing plate 6, while the clamping plate 12 connected to the floating plate 10 on the lower surface of the lower material tray is fixed. After the flipping body 1 completes the 180° flip, the lower material tray is at the top and the upper material tray is at the bottom. The chip in the lower material tray is separated from the original groove hole under the action of gravity, and because the groove holes of the material tray and the upper material tray correspond to each other in the closed state, the chip can fall into the upper material tray, and in this process, the transfer of the chip can be assisted by the knocking component. After the transfer is completed, since both the upper opening and closing components and the lower opening and closing components can be opened and closed, the upper material tray located at the bottom is removed, and the surface of the chip in the upper material tray is inspected for defects, and the lower material tray located at the top can also be taken away by the clamp, and the chip loading and transportation are repeated.
