Description

Technical Field

[0001] This utility model relates to the field of wafer sorting technology, and in particular to a material tray feeding mechanism. Background Technology

[0002] Wafer sorting machines require trays during the wafer sorting process, which are stacked in a hopper. Existing tray feeding mechanisms employ a lifting structure for easy tray removal from the hopper, requiring significant space for this lifting and lowering, thus increasing the overall size of the wafer sorting machine. For example, utility model patent CN222410143U requires a second lifting assembly to move a second hopper up and down when removing the tray from the hopper. This second hopper also requires considerable space for lifting and lowering. Utility Model Content

[0003] In order to solve at least one of the above-mentioned technical problems, the purpose of this utility model is to provide a material tray feeding mechanism.

[0004] To achieve the above objectives, the material feeding mechanism proposed in this utility model is applied to a wafer sorting machine, the material feeding mechanism comprising:

[0005] Mounting bracket, fixed to the wafer sorter;

[0006] A storage rack, fixed to the mounting frame, is provided with a storage cavity for stacked feeding trays, and a discharge port is provided at the bottom of the storage cavity;

[0007] A limiting module is provided corresponding to the discharge port. The limiting module includes a limiting part and a first driving part. The limiting part has an open position and a closed position relative to the storage rack. The first driving part is used to drive the limiting part to reciprocate between the open position and the closed position. In the open position, the tray can pass through the discharge port. In the closed position, the limiting part and the discharge port form a first channel and can receive the tray.

[0008] The material loading module has a material picking position relative to the storage rack. The material loading module includes a supporting part and a second driving part. At the material picking position, the supporting part is located below the discharge port. The second driving part can drive the supporting part to move towards the discharge port and receive the material tray through the first channel; or drive the supporting part to move away from the discharge port.

[0009] In one embodiment, a first gap is formed between the stacked trays;

[0010] The limiting part includes a mounting plate installed on the first driving part and a plug plate provided on the mounting plate, the plug plate being able to be inserted into the first gap.

[0011] In one embodiment, the first driving unit includes a first linear driving module, the limiting part is mounted on the first linear driving module, and the first linear driving module drives the limiting part to move along the X direction, so that the limiting part reciprocates between the open position and the closed position;

[0012] And / or, the first drive unit is mounted on the mounting bracket.

[0013] In one embodiment, the limiting part and the first driving part are each configured as two sets, and are respectively located on opposite sides of the storage cavity.

[0014] In one embodiment, the storage rack is fixed to the mounting frame by screws.

[0015] In one embodiment, the second driving unit includes a second linear driving module, and the carrier unit is mounted on the second linear driving module. The second linear driving module is capable of driving the carrier unit to move along the Z direction so that the carrier unit moves toward or away from the discharge port.

[0016] In one embodiment, the material loading module has a discharge position relative to the storage rack, and at the discharge position, the material loading module can output a material tray;

[0017] The material feeding mechanism also includes a drive component, which drives the material loading module to reciprocate between the material picking position and the material discharging position.

[0018] In one embodiment, the driving assembly includes a guide rail, a driving member, and a slider. The guide rail extends along the Y direction, the driving member is capable of driving the slider to move along the guide rail, and the material loading module is mounted on the slider.

[0019] In one embodiment, the material loading module further includes a mounting base and a pushing component mounted on the mounting base. The mounting base is mounted on the driving component, and the second driving part is mounted on the mounting base. The pushing component is capable of pushing the material tray on the carrying part to move.

[0020] In one embodiment, the feeding assembly includes a third linear drive module and a feeding plate mounted on the third linear drive module, wherein the third linear drive module is capable of driving the feeding plate to move along the Y direction.

[0021] The technical solution of this utility model adopts a fixed storage rack with a storage cavity and a discharge port at the bottom. When the material loading module picks up material, the storage rack does not move, and the second drive unit drives the bearing unit to remove the material tray from the storage cavity. At this time, the storage rack does not move. This avoids the situation where the material tower needs a large amount of space to move when picking up material, which would cause the material tray feeding mechanism to need a large amount of space. This solves the technical problems existing in the prior art. Attached Figure Description

[0040] This utility model proposes a material tray feeding mechanism for use in a wafer sorting machine. Furthermore, in some embodiments, the wafer sorting machine is provided with a receiving position for receiving the material trays output from the material tray feeding mechanism.

[0041] Please see Figure 1 , Figure 2 In one embodiment of this utility model, the material tray feeding mechanism includes:

[0042] Mounting bracket 100 is fixed to the wafer sorter, wherein the mounting bracket 100 can be fixed to the wafer sorter by means of screws;

[0043] A storage rack 200 is fixed to the mounting frame 100, wherein the storage rack 200 can be fixed to the mounting frame 100 by screws; a storage cavity 210 is provided, the storage cavity 210 is used for the stacked arrangement of the feeding trays 500, and the bottom of the storage cavity 210 is provided with a discharge port 220.

[0044] Limit module 300, reference Figure 4 Corresponding to the discharge port 220, the limiting module 300 includes a limiting part 310 and a first driving part 320. It should be noted that the limiting module 300 can be installed on the storage rack 200 or the mounting frame 100; the specific method is not limited in this embodiment. Further, the limiting part 310 has an open position and a closed position relative to the storage rack 200. The first driving part 320 drives the limiting part 310 to reciprocate between the open and closed positions. In the open position, the material tray 500 can pass through the discharge port 220. It should be noted that at this time, the material tray in the storage cavity 210 can be output to the outside of the storage cavity 210 through the discharge port 220. The specific position of the limiting part 310 is not limited in this embodiment; only... When the limiting part 310 is in the open position, it is sufficient that the material tray 500 can be output outward through the discharge port 220. In the closed position, the limiting part 310 and the discharge port 220 form a first channel and can receive the material tray 500. It should be noted that in the closed position, the limiting part 310 and the discharge port 220 form a first channel. It can be understood that the discharge port 220 is not completely closed at this time. Since the limiting part 310 can receive the material tray 500 in the closed position, that is, in the closed position, the limiting part 310 can prevent the material tray 500 from being output outward from the discharge port 220. Furthermore, in this embodiment, there is no specific restriction on the closed position, as long as the limiting part 310 and the discharge port 220 can form a first channel and the limiting part 310 can receive the material tray 500.

[0045] Material loading module 400, reference Figure 6The material receiving module 400 includes a material receiving position relative to the storage rack 200, and includes a supporting part 410 and a second driving part 420. At the material receiving position, the supporting part 410 is located below the discharge port 220. The second driving part 420 can drive the supporting part 410 to move towards the discharge port 220 to receive the material tray through the first channel, or drive the supporting part 410 to move away from the discharge port 220. When the material loading module 400 picks up material, the second drive unit 420 drives the bearing unit 410 to move towards the discharge port 220, allowing the bearing unit 410 to pass through the first channel and receive the material tray. The first channel is constructed by the limiting unit 310 and the discharge port 220. After the bearing unit 410 passes through the first channel, it can receive the material tray in the storage cavity 210. When the bearing unit 410 receives the material tray in the storage cavity 210, the first drive unit 320 drives the limiting unit 310, moving it from the closed position to the open position. Then, the second drive unit 420 drives the bearing unit 410 to move a certain distance away from the discharge port 220. When moving away from the discharge port 220, the material tray 500 can also be output from the discharge port 220 under its own weight. It should be noted that when it is necessary to take out a material tray 500 from the storage chamber 210, the supporting part 410 can receive the material tray and the limiting part 310 can move from the closed position to the open position. The supporting part 410 moves away from the discharge port 220 by the distance of one material tray. At this time, one material tray will be output from the discharge port 220. Then the limiting part 310 moves from the open position to the closed position and receives the remaining material tray. At the same time, the second driving part 420 continuously drives the receiving part and the material tray provided on the receiving part to move away from the discharge port 220.

[0046] It should be noted that in this embodiment, when the limiting part 310 is in the closed position, it can receive the tray 500. There are several ways in which the limiting part 310 and the tray 500 can receive each other. One method is that after the trays 500 are stacked, a gap 510 is provided between adjacent trays 500. (Refer to...) Figure 3At this time, the limiting part 310 can be inserted into the gap 510 between two adjacent material trays 500, thereby receiving the material tray 500 near the discharge port 220 through the limiting part 310, thus receiving the stacked material trays 500. Multiple material trays 500 are stacked and numbered from the discharge port 220 upwards, namely material tray 500A, material tray 500B, material tray 500C, etc. When the receiving part is picking up material, the receiving part first receives material tray 500A. When receiving material tray 500A, When the limiting part 310 moves from the closed position to the open position, the receiving part drives the material tray 500A to move away from the discharge port 220 by a distance of one material tray 500. At this time, the gap 510 between the material tray 500A and the material tray 500B corresponds to the limiting part 310. Then the limiting part 310 moves from the open position to the closed position. When the limiting part 310 is in the closed position, the limiting part 310 can receive the material tray 500B. By receiving the material tray 500B, multiple stacked material trays 500 can be received.

[0047] When there is no gap 510 between two adjacent trays 500 (not shown), a slot that mates with the limiting part 310 is provided on the outer side of the tray 500. It should be noted that when a slot is provided on the outer side of the tray 500, the limiting part 310 is provided with a plug-in part corresponding to the slot. When the receiving part moves the tray 500A away from the discharge port 220 by a distance of one tray 500, the slot on the tray 500B can correspond to the limiting part 310. When the limiting part 310 moves from the open position to the closed position, the plug-in part on the limiting part 310 can be inserted into the slot in the tray 500B to receive the tray 500B.

[0048] This application employs a fixed storage rack 200 with a storage cavity 210 and a discharge port 220 at the bottom. When the loading module 400 retrieves material, the storage rack 200 remains stationary, while the second drive unit 420 drives the bearing unit 410 to remove the material tray from the storage cavity 210. At this time, the storage rack 200 does not shift. This avoids the situation where the material tower needs a large amount of space to move due to the material tray 500 feeding mechanism when retrieving material, thus solving the technical problems existing in the prior art.

[0049] In one embodiment, reference Figure 3 , Figure 4 , Figure 5 A first gap 510 is formed between the stacked trays 500; the limiting part 310 includes a mounting plate 311 mounted on the first driving part 320 and an insert plate 312 disposed on the mounting plate 311. The insert plate 312 can be inserted into the first gap 510, wherein the first driving part 320 drives the mounting plate 311 to move the insert plate 312 so that the insert plate 312 is inserted into the first gap 510.

[0050] In one embodiment, reference Figure 4 The first driving unit 320 includes a first linear driving module, and the limiting part 310 is installed on the first linear driving module. It should be noted that the mounting plate 311 on the limiting part 310 is installed on the first linear driving module by screw fastening. The first linear driving module drives the limiting part 310 to move along the X direction, so that the limiting part 310 reciprocates between the open position and the closed position.

[0051] In one embodiment, reference Figure 1 , Figure 4 The first drive unit 320 is mounted on the mounting bracket 100, wherein the first linear drive module is fixed to the mounting bracket 100 by screw fastening. Further, in some embodiments, the first linear drive module may be a push rod motor assembly or a cylinder assembly.

[0052] In one embodiment, reference Figure 2 The limiting part 310 and the first driving part 320 are each configured in two sets and are respectively located on opposite sides of the storage cavity 210. It should be noted that one limiting part 310 and one first driving part 320 are located on one side of the storage cavity 210, and the other limiting part 310 and the other first driving part 320 are located on the other side of the storage cavity 210, so that both limiting parts 310 in the limiting module 300 can simultaneously receive the material box. It should be noted that in some embodiments, only one limiting part 310 and one first driving part 320 are provided.

[0053] In one embodiment, reference Figure 6 The second drive unit 420 includes a second linear drive module, and the carrier unit 410 is mounted on the second linear drive module. The second linear drive module can drive the carrier unit 410 to move along the Z direction, so that the carrier unit 410 moves toward or away from the discharge port 220. It can be understood that the second linear drive module drives the carrier unit 410 to move along the Z direction, and when the carrier unit 410 moves toward the Z direction, it can move toward or away from the discharge port 220. Further, in some embodiments, the first linear drive module can be a push rod motor assembly or a cylinder assembly.

[0054] In one embodiment, reference Figure 2As shown in Figure 6, the material loading module 400 has a discharge position relative to the storage rack 200. At the discharge position, the material loading module 400 can output a material tray 500. The material tray 500 feeding mechanism also includes a drive component 600, which is used to drive the material loading module 400 to reciprocate between the picking position and the discharge position. It should be noted that at the discharge position, the material loading module 400 can output the material tray 500 to the receiving position. The receiving position in the wafer sorting machine can receive the material tray output by the material loading module 400. Furthermore, in some embodiments, the drive component 600 can be a multi-axis robotic arm. In this case, the material loading module 400 is installed on the multi-axis robotic arm, and the multi-axis robotic arm drives the material loading module 400 to reciprocate between the discharge position and the picking position.

[0055] In one embodiment, reference Figure 1 The driving component 600 includes a guide rail 610, a driving element 620, and a slider 630. The guide rail 610 extends along the Y direction. The driving element 620 can drive the slider 630 to move along the guide rail 610. The material loading module 400 is mounted on the slider 630. Further, in some embodiments, the driving element 620 can be a drive motor. The driving element 620 drives the slider 630 to move along the guide rail 610. When the slider 630 moves along the guide rail 610, it can drive the material loading module 400 to move. It should be noted that in this embodiment, the material picking position and the material discharging position are arranged along the Y direction. Further, the driving element 620 can drive the slider 630 to move via a belt module. The slider 630 is slidably mounted on the guide rail 610.

[0056] In one embodiment, reference Figure 1 , Figure 6 The material loading module 400 further includes a mounting base and a pushing component 430 mounted on the mounting base. The mounting base is mounted on the drive component 600, and the second drive unit 420 is mounted on the mounting base. The pushing component 430 can push the material tray 500 on the support unit 410 to move. It should be noted that the mounting base is mounted on the slider 630 in the drive component 600. When the slider 630 drives the mounting base to the discharge position, the pushing component 430 can push the material tray 500 on the support unit 410 to move, thereby pushing the material tray 500 to the receiving position. After the pushing is completed, the drive component 600 continues to drive the mounting base, moving the mounting base from the discharge position to the picking position. At this time, the material loading module 400 continues to pick up materials.

[0057] In one embodiment, reference Figure 6The feeding assembly 430 includes a third linear drive module 431 and a feeding plate 432 mounted on the third linear drive module 431. The third linear drive module 431 can drive the feeding plate 432 to move along the Y direction. The third linear drive module 431 can be a push rod motor assembly or a cylinder assembly. The third linear drive module drives the feeding plate 432 to move, thereby causing the feeding plate 432 to push the material tray 500 to move.
