[0029] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0030] In some existing wafer rejection devices, silicon wafers are directly transferred to the loading box 100 by the action of rejection rollers. However, the silicon wafers entering the loading box 100 are prone to collisions, which can cause damage to the silicon wafers.

[0031] The wafer rejection device provided in this application embodiment can reduce the collision between silicon wafers during the process of the wafers being transferred from the rejection structure to the loading box 100, thereby reducing the occurrence of damage to the silicon wafers.

[0032] The following describes in detail, with reference to the accompanying drawings, the specific structure of a sheet chipping device provided by this utility model and its corresponding technical effects.

[0033] Please refer to Figure 1 This utility model provides a sheet rejection device including a loading box 100 and a rejection assembly (not shown). The loading box 100 is provided with multiple isolation baffles 140, which divide the loading box into multiple loading cavities 150 arranged sequentially along a first direction. The loading cavities 150 are used to accommodate sheet metal. The rejection assembly includes multiple rejection structures arranged sequentially along the first direction, which are used to transfer sheet metal from the machine to the loading cavities 150.

[0034] It should be noted that the wafers in this embodiment can be understood as silicon wafers. That is, by setting the isolation baffle 140, the loading box 100 can be divided into multiple mutually isolated loading cavities 150, thereby reducing the contact between silicon wafers in each loading cavity 150 and reducing the occurrence of silicon wafer damage.

[0035] Optionally, in order to further reduce the damage to the silicon wafer when it is transferred to the loading chamber 150 by the wafer rejection structure, in some embodiments, a buffer pad is also provided on the bottom plate 110 of the loading box. The buffer pad is made of a flexible material, such as foam, plastic or rubber pad, so as to absorb the impact force when the silicon wafer falls into the loading box and reduce the risk of microcracks in the silicon wafer.

[0036] In detail, in this embodiment, the loading box includes a bottom plate 110, a rear plate 120, and two side plates 130 spaced apart along a first direction. The two side plates 130 are respectively disposed on both sides of the bottom plate 110 along the first direction. The adjacent sides of the side plates 130 are respectively connected to the bottom plate 110 and the rear plate 120. A plurality of partitions are disposed between the two side plates 130. Similarly, the adjacent sides of the partitions are respectively connected to the bottom plate 110 and the rear plate 120.

[0037] In some embodiments, in order to protect the silicon wafer from easy microcracks in the loading cavity 150, at least one of the partition, bottom plate 110, back plate 120 and side plate 130 is made of a flexible material.

[0038] In some embodiments, in order to facilitate the timely detection of whether there are silicon wafers on the machine by the rejection assembly, so as to ensure that the rejection assembly can promptly transfer the silicon wafers on the machine to the loading box 100 when the machine fails to operate.

[0039] The wafer rejection device also includes a detection element, which is mounted on the rejection structure and is used to detect whether a wafer is present on the machine. Understandably, the detection element can communicate with the rejection assembly. When the detection element detects a wafer on the machine, it can send a signal to the rejection assembly, and the rejection structure of the rejection assembly can promptly transfer the silicon wafer into the loading box 100.

[0040] It should be noted that the detection component can be an image detection component, such as an image detection structure like a camera.

[0041] The wafer rejection structure can be a wafer rejection roller. Since the wafer rejection roller is a conventional device in silicon wafer rejection equipment, the specific structure of the wafer rejection roller will not be described in detail here.

[0042] Please refer to Figure 2 Optionally, the sheet rejection device further includes a transfer isolation component 300, which is used to place isolation sheets 500 into the loading cavity 150, and the isolation sheets 500 are used to separate adjacent sheets in the loading cavity 150.

[0043] Understandably, when there is a silicon wafer in the loading cavity 150, when the next silicon wafer is placed, an isolation plate 500 can be placed above the silicon wafer by the transfer isolation component 300. The isolation plate 500 can reduce the contact between the next silicon wafer and the silicon wafer below the isolation plate 500, thereby reducing the occurrence of microcracks after the silicon wafers come into contact.

[0044] In detail, the transfer isolation assembly 300 is located on the upper side of the loading box 100 to facilitate the placement of the isolation sheet 500 into the loading cavity 150. The sheet rejection device also includes an isolation box 400, which is spaced apart from the loading box 100 along a second direction. The isolation box 400 is used to store the isolation sheet 500, and the transfer isolation assembly 300 is used to transfer the isolation sheet 500 in the isolation box 400 to the loading box 100. The first direction and the second direction form an angle.

[0045] Of course, in some other embodiments, the isolation box 400 and the filling box 100 may also be spaced apart along the first direction.

[0046] The transfer isolation assembly 300 includes a first guide rail 310, a drive member 330, and a gripper 320. The first guide rail 310 extends along a second direction, the drive member 330 can move along the second direction on the first guide rail 310, and the drive member 330 is connected to the gripper 320 to drive the gripper 320 to move in the vertical direction. The gripper 320 is used to pick up and put down the isolation sheet 500.

[0047] The first guide rail 310 and the driving component 330 can be slidably connected to ensure the stability of the driving component 330's movement in the second direction.

[0048] Optionally, in order to reduce the occurrence of silicon wafer damage due to contact between adjacent silicon wafers in each loading cavity 150, the number of isolation boxes 400 and transfer isolation components 300 are multiple and are set in a one-to-one correspondence, so that each transfer isolation component 300 can pick up the isolation paper from one isolation box 400.

[0049] Of course, in some other embodiments, the number of isolation boxes 400 may also be one, and each transfer isolation component 300 can pick up isolation paper from the isolation box 400.

[0050] Multiple transfer isolation components 300 are spaced apart along the first direction, and the multiple transfer isolation components 300 are arranged one-to-one with multiple loading cavities 150.

[0051] In this embodiment, the driving component 330 is one of a driving cylinder, a driving electric cylinder, or a driving hydraulic cylinder. Specifically, in this embodiment, the driving component 330 is a driving cylinder to improve the accuracy of driving the gripper 320.

[0052] In this embodiment, the gripper 320 is a gripping suction cup to improve the stability of gripping the isolation plate 500.

[0053] Optionally, the separator 500 is a separator paper, which can be made of a flexible material. The separator paper has a certain thickness, thereby reducing the damage caused by contact between adjacent silicon wafers within the loading cavity 150.

[0054] In summary, the wafer rejection device provided in this embodiment of the present invention includes a loading box 100 and a rejection assembly. The loading box 100 is provided with multiple isolation baffles 140, which divide the loading box into multiple loading cavities 150 arranged sequentially along a first direction. The loading cavities 150 are used to accommodate wafers. The rejection assembly includes multiple rejection structures arranged sequentially along the first direction, which are used to transfer wafers from the machine to the loading cavities 150. By providing the isolation baffles 140, the loading box 100 can be divided into multiple mutually isolated loading cavities 150, thereby reducing the contact between silicon wafers within each loading cavity 150 and minimizing the possibility of wafer damage.

[0055] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
