Sheet-like brittle product air-throwing downer

Abstract

This utility model discloses an air-throwing device for brittle sheet-like products, including a tilted, top-opening material box; a feeding suction cup positioned above the material box; and an air jet assembly including a jet nozzle positioned above the material box and corresponding to its lower end. When the product is released by the feeding suction cup, the jet nozzle sprays air onto one end of the parallel-positioned product, causing the product to fall into the material box at the same tilt as the material box. By using the air jet assembly, when the product is released by the feeding suction cup, the jet nozzle sprays air onto one end of the parallel-positioned product, tilting the product. The jet nozzle's position corresponding to the lower end of the material box ensures that the product's tilt aligns with the tilted material box. Therefore, when the product falls into the material box, both ends almost simultaneously contact the two ends of the internal support plate, reducing the probability of product injury from impact.

Description

Technical Field

[0001] This utility model belongs to the field of silicon wafer feeding technology, and in particular relates to an air-throwing feeding device for brittle sheet products. Background Technology

[0002] For brittle, sheet-like products, such as silicon wafers (monocrystalline silicon, length: 210mm, width: 105mm, thickness: 0.11mm), the production line often uses a suction cup gripping and air-throwing method to collect the wafers into the box. In order to ensure that the wafers are collected neatly after entering the box, the box is often placed at an angle, so that the products can slide neatly when entering the box.

[0003] However, since the silicon wafer is initially horizontal after being released by the suction cup, it will fall horizontally into the cassette. Since the cassette is placed at an angle, the silicon wafer will collide with the higher end of the cassette support plate when it falls into the cassette, which can easily cause damage to the silicon wafer inside the cassette. Utility Model Content

An air jet assembly, the air jet assembly including an air jet nozzle, the air jet nozzle being disposed above the material box and corresponding to the lower end of the material box; When the product is released by the feeding suction cup, the jet nozzle sprays air onto one end of the parallel product, causing the product to fall into the material box at the same tilted position as the material box.

[0005] As a preferred embodiment of the above technical solution, the jet assembly further includes an air pump, the output end of which is connected to the jet nozzle via an air pipe.

[0006] As a preferred embodiment of the above technical solution, a flow meter is also included, which is installed on the air tube.

[0007] As a preferred embodiment of the above technical solution, it further includes a fixed frame and a conveyor frame. The material box is fixedly mounted on the fixed frame, the unloading suction cup is mounted on the conveyor frame, and a sensor is also mounted on the conveyor frame near the unloading suction cup.

[0009] The beneficial effects of this utility model are as follows: This invention utilizes a jet assembly that, when the product is released by the feeding suction cup, jets are directed at one end of the parallel product, causing it to tilt. The jet nozzle is positioned at the bottom of the material box, ensuring that the product's tilt aligns with the tilted material box. Consequently, when the product falls into the material box, both ends of the product almost simultaneously contact the two ends of the internal support plate, reducing the probability of product damage.

Flow meter. Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0012] Example like Figure 1 As shown, Figure 1 The diagram shown is an overall schematic of the feeding device in the embodiment; This device includes: A tilted, top-opening material box 20; The material suction cup 30 is positioned above the material box 20. The jet assembly includes a jet nozzle 41, which is positioned above the material box 20 and corresponds to the lower end of the material box 20.

[0013] The tilted placement of the material box 20 refers to the state in which the support plate used to support the silicon wafer 1 in its receiving cavity is tilted (one side is higher and the other side is lower). Figure 1 In the diagram, A represents the high end of the tilted material box 20, and B represents the low end of the tilted material box 20.

[0014] The unloading suction cup 30 is a Bernoulli suction cup with transfer and unloading functions in the prior art. The process of the unloading suction cup 30 releasing the silicon wafer 1 adsorbed on its bottom surface is called unloading of silicon wafer 1. The jet assembly is configured such that when the silicon wafer 1 is released by the unloading suction cup 30, the jet nozzle 41 sprays air onto one end of the parallel silicon wafer 1, causing the silicon wafer 1 to tilt. The jet nozzle 41 is positioned at the lower end of the material box 20, so that the tilting posture of the silicon wafer 1 is consistent with that of the tilted material box 20. Therefore, when the silicon wafer 1 falls into the material box 20, both ends of it almost simultaneously come into contact with the two ends of the support plate inside the material box 20, which reduces the probability of the silicon wafer 1 being damaged.

[0015] like Figure 1 As shown, Figure 1 The diagram shown is an overall schematic of the feeding device in the embodiment; The jet assembly also includes an air pump 42, the output of which is connected to the jet nozzle 41 via an air pipe 43.

[0016] It also includes a flow meter 44, which is mounted on the air tube 43.

[0017] Both the air pump 42 and the flow meter 44 are existing technologies. The air pump 42 is the air supply source. The air pump 42 delivers gas (high-pressure gas) to the nozzle 41 and sprays it out through the air pipe 43 connected to its output end.

[0018] The flow meter 44 can monitor and adjust the flow rate of the gas ejected from the nozzle 41 according to the actual situation.

[0019] like Figure 1 As shown, Figure 1 The diagram shown is an overall schematic of the feeding device in the embodiment; This device also includes: The fixed frame 11 and the conveyor frame 12 are fixedly mounted. The material box 20 is fixedly mounted on the fixed frame 11, and the unloading suction cup 30 is mounted on the conveyor frame 12.

[0020] A sensor (not shown in the figure) is also installed on the conveyor frame 12 near the unloading suction cup 30. The sensor monitors the unloading process of the unloading suction cup 30 and, through an external controller, makes the jet nozzle 41 start at the moment the unloading suction cup 30 unloads material.

[0021] The sensor can be a photoelectric sensor in the prior art: a photoelectric sensor can determine the presence or absence of an object by emitting a light beam and detecting the reflected light. In this device, it can be used to detect whether the unloading suction cup 30 has released the silicon wafer 1. For example, when the silicon wafer 1 is released, it will interrupt or change the state of the light beam, thereby triggering the corresponding action.

[0022] like Figure 2 As shown, Figure 2 The diagram shown is a three-dimensional schematic of the placement of the material box and silicon wafer in the embodiment; The material box 20 includes a base plate 21, a side plate 22, and a side block 23. The base plate 21, the side plate 22, and the side block 23 enclose a box body that can accommodate the silicon wafer 1.

[0023] The base plate 21 is the support plate for supporting the silicon wafer 1. The side plate 22 and the side block 23 are set at the adjacent edges of the upper end of the base plate 21 to form the material box 20.

[0024] Working principle: When this device is in use, the jet nozzle 41 of the jet assembly jets air onto one end of the parallel silicon wafer 1 when the silicon wafer 1 is released by the unloading suction cup 30, causing the silicon wafer 1 to tilt. The jet nozzle 41 is positioned at the lower end of the material box 20, so that the silicon wafer 1 is in the same tilt state as the tilted material box 20 and falls smoothly into the material box 20.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
