[0049] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0050] Please see Figure 1 and Figure 2 This application provides the following technical solutions:
[0051] A chip feeding fixture includes a first feeding unit 1, a first picking unit 2, an adjustment unit 3, and a second feeding unit 4 arranged sequentially in the feeding to discharging direction. The first feeding unit 1 holds the chips to be fed, and the chips are stacked within the first feeding unit 1. The first picking unit 2 is located on the discharging side of the first feeding unit 1 and is used to pick up the chips from the first feeding unit 1. The adjustment unit 3 is located on the side of the first picking unit 2 away from the first feeding unit 1, and can receive the chips picked up by the first picking unit 2 and adjust the orientation of the chips. The second feeding unit 4 is connected to the adjustment unit 3 and can feed the chips from the adjustment unit 3.
[0052] like Figure 1 As shown, the first feeding unit 1, the first picking unit 2, the adjustment unit 3, and the second feeding unit 4 are distributed on the base 5, which is a planar support structure. Considering that this fixture needs to be used in chip packaging processes, each unit structure is set on the planar base 5 to facilitate the unified setting of other packaging process units in the future.
[0053] As for the initial supply of materials for chips, such as Figure 2 As shown, chips are often combined with Figure 2 In this process, chips are placed on rectangular trays or wafers in a rectangular array. However, because chips are often rectangular wafers, the orientation of certain rows of chips on the tray may become disordered during production. The first feeding unit 1 in this solution separates the stacked trays into individual trays for feeding. Then, the first picking unit 2 removes the chips from the trays and places them into the adjustment unit 3 for orientation determination and adjustment, thereby correcting the chip orientation and ensuring continuous feeding.
[0054] Based on the above implementation plan, see Figure 2The first feeding unit 1 includes a stacking section 11 and a placement section 13 arranged in a straight line. The stacking section 11 is used to stack and place chip trays transferred from an external mechanism. The placement section 13 is used to place single-layer trays extracted from the stacking section 11. A first conveying section 12 is provided on the upper or lower side of the stacking section 11, and the chip trays in the stacking section 11 are taken out one by one and placed in the placement section 13. The placement section 13 needs to be located in a position that can be grasped by the first picking unit 2.
[0055] The stacking section 11 of the first feeding unit 1 and the external feeding mechanism can be used to select the corresponding feeding robot or manually place the material trays according to the actual situation. If the first conveying section 12 is above the stacking section 11, a structure such as a vacuum suction cup can be used to grab the chip material trays one by one from top to bottom and transfer them.
[0056] Based on the above implementation plan, see Figure 2 This solution provides an implementation structure for the first conveying unit 12 located below the stacking unit 11. The first conveying unit 12 includes a conveying assembly 121 disposed below the stacking unit 11 and the placement unit 13. The conveying assembly 121 has a conveyor belt structure, and the conveying direction of the conveying assembly 121 is from the stacking unit 11 towards the placement unit 13. To ensure that the stacked trays on the upper side do not cause interference during chip tray conveying, this solution also includes a clamping assembly 122. The clamping assembly 122 includes several clamping members disposed on both sides of the stacking unit 11. The clamping members can clamp the chips on the stacking unit 11. The clamping members can be implemented using cylinders. By engaging the corresponding chip tray clamping block structure with the cylinders, the upper trays are clamped, leaving only the bottommost chip tray. The bottommost chip tray can then be transferred to the placement unit 13 along with the conveying assembly 121. The chip tray clamping block only needs to be able to fix the upper tray stack; the specific structure is not limited.
[0057] This embodiment achieves the separation and feeding of a single chip tray from the tray stack. Compared to the structure where the conveyor assembly 121 is located above, this embodiment involves fewer actions, thus offering advantages in terms of stability and ease of maintenance.
[0058] Based on the above implementation scheme, two sets of stacking sections 11, a first conveying section 12, and a placement section 13 can be arranged side by side on the base 5 to form two or more parallel feeding structures. In this state, a transverse section 14 can be provided, which spans across the two sets of structures. At this time, the external feeding structure can be connected to a single stacking section 11, and the chip tray stack can be transferred laterally by means of the transverse section 14.
[0059] The specific structure of the transverse section 14 will not be described in detail here; it is sufficient that it can grasp the entire chip tray and transverse it.
[0060] Based on the above implementation plan, see Figure 1 and Figure 4 The first picking unit 2 includes a main picking track 21 and a picking assembly 22. The main picking track 21 is arranged along the direction from the placement section 13 to the adjustment unit 3. The picking assembly 22 is connected to the main picking track 21 and can slide along the main picking track 21. The picking assembly 22 includes several picking grippers 221 arranged downwards. The main picking track 21 is mainly set up to guide the movement of the picking assembly 22, which is used to pick up the chips on the placement section 13 from the chip tray and transport them to the adjustment unit 3. The picking grippers 221 can optionally be equipped with multiple gripping heads with negative pressure adsorption function, and the size and position of the gripping heads can correspond to the chips.
[0061] It should be noted here that if a multi-row feeding structure is set according to the above implementation scheme, the first feeding unit 2 will add an auxiliary feeding track 23. The auxiliary feeding track 23 will drive the feeding gripper 221 to move laterally. The direction of movement is in line with the setting direction of the above two rows of feeding structures and is parallel to the lateral movement part 14.
[0062] Based on the above implementation plan, see Figure 3 and Figure 5 The adjustment unit 3 includes a feed shuttle 31 and an adjustment sensor 32. The feed shuttle 31 includes several rotatable chip holders 311, each chip holder 311 can hold one chip; the adjustment sensor 32 is located above the feed shuttle 31 and can provide feedback on the orientation of the chip on the chip holder 311.
[0063] The chips picked up by the first picking unit 2 are placed according to the chip holder 311, which has a groove corresponding to each individual chip. The adjustment sensor 32 in this solution uses an artificial intelligence vision system with image acquisition capabilities. An image is captured by a camera pointing towards the chip holder 311, and then the existing artificial intelligence vision system is used to determine the chip orientation and provide feedback. For the artificial intelligence vision system, existing technology can be used; the specific implementation method is not the focus of this solution and will not be elaborated here.
[0064] Based on the above implementation scheme, preferably, the shuttle 31 also includes a shuttle base 313, which is mounted on the base 5, and the chip holders 311 are rotatably mounted on the shuttle base 313. An adjustment component 312 is provided on the shuttle base 313, which can drive all chip holders 311 on the same shuttle 31 to rotate synchronously. Because the chips in each row on the chip tray have the same orientation during production, it is unlikely that a single chip will be oriented incorrectly; rather, the entire row of chips will be oriented incorrectly. Therefore, this scheme uses an adjustment component 312 to ensure that all chip holders 311 rotate uniformly, resulting in higher efficiency.
[0065] Based on the above implementation plan, see Figure 3 and Figure 5 The adjustment assembly 312 includes a drive gear corresponding to each chip holder 311, which is coaxially and fixedly connected to the chip holder 311. A drive bar 3121 is provided on one side of the drive gear, and the drive bar 3121 has teeth that mesh with the drive gear. A drive rail 3122 is fixedly connected to the shuttle base 313, and the drive bar 3121 is slidably connected to the drive rail 3122. With this solution, the chip holder 311 can be rotated and adjusted by simply using a corresponding push-pull mechanism to move the drive bar 3121. A cylinder can be used to drive the drive bar 3121. It should be noted that, for ease of demonstration, the attached diagram of this solution hides some structural components, such as some of the aforementioned adjustment sensors 32 and some of the chip holders 311.
[0066] Based on the above implementation scheme, the second feeding unit 4 includes a conveying gripper 41 and a second conveying section 42. The conveying gripper 41 can grip the chip on the adjustment unit 3, and a gripping head with negative pressure adsorption function can be used. The second conveying section 42 is connected to the conveying gripper 41 and can drive the conveying gripper 41 to move. The second conveying section 42 adopts a belt and pulley structure or other mechanism to drive the conveying gripper 41 to move horizontally. Through the second feeding unit 4, the feeding of the chip with the adjusted direction is completed for use in subsequent working steps.
[0067] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
