Description

Technical Field

[0001] This utility model relates to the field of silicon wafer production technology, and in particular to a degumming machine feeding and transfer device. Background Technology

[0002] After the silicon wafer de-adhesive machine finishes de-adhesive removal, the silicon wafers need to be removed in batches, sorted, and de-adhesive removed (residual adhesive on the surface of the silicon wafer stack), and then loaded into the insertion machine's loading box for the next process.

[0003] Currently, the unloading of silicon wafers from degumming machines is mainly done manually, which involves repeated handling and is time-consuming. Furthermore, operators at the unloading station must wear thick rubber gloves for extended periods, increasing the risk of errors and losses. Therefore, for the silicon wafer stacks after degumming, an automated device is needed to replace manual unloading, transfer, and pre-processing between the next process step. Utility Model Content

[0004] This application addresses the shortcomings of the prior art by providing a degumming machine material transfer device that can automatically complete the transfer, shaping, and degumming of silicon wafers, thereby improving production efficiency and reducing manual intervention.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A degumming machine unloading and transfer device includes an unloading platform, which is equipped with a transfer robot, a degumming machine discharge water tank, a loading line, and a processing workbench. The transfer robot is configured to scoop out a silicon wafer stack from the degumming machine discharge water tank, transfer the silicon wafer stack to the processing workbench, and then transfer the processed silicon wafer stack to an empty box in the loading line for the next process.

[0007] Furthermore, the transfer robot is a six-axis robot.

[0008] Furthermore, the free end of the transfer robot is provided with a clamp for gripping the silicon wafer stack. The clamp includes a flange provided at the end of the joint of the transfer robot. A silicon wafer shovel is suspended on one side below the flange. The silicon wafer shovel has an L-shaped cross-section. A nozzle is also provided on the side of the flange adjacent to the silicon wafer shovel.

[0009] Furthermore, a clamping mechanism is also arranged on the silicon wafer shovel. The clamping mechanism includes two sets of clamping cylinders arranged opposite to each other. The strokes of the clamping cylinders are arranged opposite to each other. The driving end of the clamping cylinder is provided with a clamping plate. The two sets of clamping plates move away from or closer to each other during the relative stroke of the clamping cylinders. The clamping cylinders are arranged on the vertical shovel surface of the silicon wafer shovel.

[0010] Furthermore, the processing workbench includes three cavities, each of which is equipped with a shaping mechanism for silicon wafer stacking and a de-adhesive removal mechanism for silicon wafer stacking.

[0011] Furthermore, the shaping mechanism includes a push cylinder, and the drive end of the push cylinder is provided with a wheel assembly mounting frame, on which symmetrically arranged are correction sponge rollers that can roll freely.

[0012] Furthermore, the adhesive removal mechanism includes at least two sets of clamping assemblies disposed in the corresponding cavity on the front and back or left and right sides, and also includes an adhesive removal unit disposed above the corresponding cavity.

[0013] Furthermore, the clamping assembly includes a clamping cylinder fixed to the cavity wall, and the driving end of the clamping cylinder is provided with a support frame, on which a flexible pad is fixedly disposed.

[0014] Furthermore, the desizing unit includes a desizing cylinder disposed on one side above the cavity, the stroke range of the desizing cylinder covering the upper surface of the silicon wafer stack, the drive end of the desizing cylinder being provided with a desizing wheel frame, and a desizing brush roller being mounted on the main shaft of the desizing wheel frame.

[0015] The beneficial effects of this utility model are as follows:

[0016] Compared with existing technologies, this utility model uses a six-axis robot to transfer silicon wafer stacks. The silicon wafer shovel at the free end of the last axis integrates a swirling nozzle, a bucket, and a clamping function. The processing workbench integrates the shaping and de-adhesive removal of the silicon wafer stacks. Through the coordinated operation of the six-axis robot, the processing workbench, and the in-plant feeding line and discharge water tank, the transfer, shaping, and de-adhesive removal of silicon wafers can be completed automatically, improving production efficiency and reducing manual intervention.

[0017] Meanwhile, during the processing of silicon wafer stacks, flexible pads and calibrating sponge rollers are used to prevent rigid contact and avoid damage to the silicon wafer surface. The system can automatically complete the transfer, shaping, and desmearing of silicon wafers, improving production efficiency and reducing manual intervention. Attached Figure Description
