Description

Technical Field

[0001] This invention relates to the field of plate-shaped crystal material transfer technology, and more specifically, to a plate-shaped crystal material transfer device and transfer method. Background Technology

[0002] Infrared optical crystal materials, CVD zinc sulfide (CVDZnS) and CVD zinc selenide (CVDZnSe), are grown vertically in a plate-like form. They are characterized by uniform texture, high purity, high density, brittleness, low hardness, and low strength. These plates are large (generally 1m × 1.5m and above) and heavy (generally 100kg and above). Care must be taken during the transfer from vertical assembly to horizontal laying to prevent significant vibration and ensure even stress distribution across the plate. Currently, the industry relies on manual assembly and transfer, which is time-consuming and labor-intensive. Even with multiple people working together, it is difficult to ensure even stress distribution, and there is a risk of material damage during the process. Furthermore, the uneven thickness and surface of the crystals mean that no equipment can currently replace manual labor. Summary of the Invention

The lifting mechanism and the rotating mechanism realize the multi-directional position adjustment of the adsorption component. The position of the adsorption component is further adjusted by sliding the adsorption component, giving the adsorption component a certain range of motion. Within this range of motion, the plate-shaped crystal material to be transferred can be adsorbed at a preset position where the bearing capacity of the plate-shaped crystal material is relatively large.

[0020] On the other hand, the present invention also provides a method for transporting plate-shaped crystal materials, using the plate-shaped crystal material transport device described in any of the above claims, comprising the following steps: rotating a rotating mechanism to drive an adsorption mechanism to rotate until the adsorption surface of the adsorption element is in a vertically outward state; moving the plate-shaped crystal material transport device until the adsorption surface of the adsorption element is in basic contact with the surface of the plate-shaped crystal material to be transported; finely adjusting the position of each adsorption element until a preset adsorption position of the plate-shaped crystal material to be transported is reached, wherein the preset adsorption position is set based on the flatness of the surface of the plate-shaped crystal material to be transported and the movable range of the adsorption element; and obtaining a preset adsorption position based on the thickness of the plate-shaped crystal material to be transported at the preset adsorption position. The maximum suction force that the adsorption position can withstand is determined; based on the maximum suction force, the adsorption force of the adsorption element is adjusted, and the plate-shaped crystal material to be transferred is adsorbed by the adsorption element; the plate-shaped crystal material to be transferred is lifted by the lifting mechanism; the plate-shaped crystal material transfer device is moved to the position where the plate-shaped crystal material is to be placed; the rotating mechanism is rotated in situ to drive the adsorption mechanism to rotate until the plate-shaped crystal material adsorbed by the adsorption element is parallel to the position to be placed; the plate-shaped crystal material is slowly lowered by the lifting mechanism until the plate-shaped crystal material is placed in the position to be placed; the adsorption force is released, so that the plate-shaped crystal material is detached from the adsorption element, and the plate-shaped crystal material is laid horizontally in the position to be placed, and the transfer is completed.

[0021] Compared with the prior art, the present invention has the following beneficial effects: The transfer method of the present invention uses the plate-shaped crystal material transfer device of the present invention. The vertical angle position of the adsorbent is adjusted by the lifting mechanism, and the vertical state of the adsorbent is adjusted to the horizontal state by the rotating mechanism. The position of each adsorbent is adjusted within its movable range by controlling the displacement of each angle of the adsorbent. Based on the maximum suction force that the preset adsorbent position can withstand, the suction force of each adsorbent is controlled by the branch pipes connected to each adsorbent, ensuring the force on each position of the material, preventing damage to the material during the transfer process, replacing manual handling, realizing mechanized transfer, and saving time and labor.

[0022] In some embodiments of the present invention, the specific process of obtaining the maximum suction force that the preset adsorption position can withstand based on the thickness of the plate-shaped crystal material to be transferred at the preset adsorption position is as follows: the thickness of the plate-shaped crystal material to be transferred at the preset adsorption position is measured by an ultrasonic thickness gauge; the maximum suction force that the preset adsorption position can withstand is obtained based on the following formula: P = T 2 M / (1.1×r 2 ×S), Pmax=P 常-P×6.895, where P is the pressure difference between the two sides of the plate-shaped crystal material to be transferred at the preset adsorption position, in psi; T is the thickness of the plate-shaped crystal material to be transferred at the preset adsorption position, in mm; when the plate-shaped crystal material to be transferred is zinc sulfide, M=15000psi, when the plate-shaped crystal material to be transferred is zinc selenide, M=8000psi; r is the radius of the force-bearing area of ​​the preset adsorption position of the plate-shaped crystal material to be transferred, that is, the radius of the adsorption area of ​​the adsorbent at the preset adsorption position of the plate-shaped crystal material to be transferred; S is a constant, S=4; Pmax is the maximum suction force that the preset adsorption position can withstand, that is, the absolute pressure, in kPa; P 常 At normal pressure, P 常 =101 kPa.

[0023] The beneficial effects of adopting the above-mentioned further technical solutions are that, based on the characteristics of CVDZnS and CVDZnSe such as brittleness, low hardness, and low strength, the present invention analyzes the force on the adsorption position during the transfer process, calculates the maximum suction force that the preset adsorption position can withstand through the above formula, and adjusts the adsorption force of the adsorption component based on the maximum suction force. This prevents the material from being damaged due to uneven stress caused by insufficient suction force, and also prevents the material from being directly damaged by excessive suction force, thus achieving successful material handling and preventing material damage due to improper stress.

[0031] In this embodiment, the rotating mechanism 4 includes a rotating frame 41 and mounting shafts 42 connected to the left and right sides of the rotating frame 41. Each mounting side frame 32 on the left and right sides of the second upright 31 of the mounting frame 3 is provided with a first fixed seat 10.

The two adsorption members 52 are located on both sides of the fourth support 511 and move together with the crossbeam as it slides up and down. Preferably, the number of crossbeams 512 is four, with a total of eight adsorption members 52. Alternatively, for another example, the crossbeam 512 can be a crossbeam structure with one end connected to the fourth support 511 and the other end extending in a direction away from the fourth support 511. In this case, each crossbeam is provided with an adsorption member 52. Preferably, the number of crossbeams 512 is eight, divided into four rows. Each row is symmetrical with respect to the fourth support 511, with a total of eight adsorption members 52. Each adsorption member 52 can move up and down with the crossbeam it is connected to.

The lifting mechanism is connected to the mounting frame and can drive the mounting frame to move up and down. The rotating mechanism is rotatably connected to the mounting frame, and the adsorption mechanism is connected to the rotating mechanism; The adsorption mechanism includes a support frame and several adsorption components. The support frame is connected to a rotating mechanism, and the adsorption components are disposed on the support frame and slidably connected to the support frame. The method for transporting the plate-shaped crystal material includes the following steps: The rotating mechanism drives the adsorption mechanism to rotate until the adsorption surface of the adsorption element is in a vertical outward state. The moving plate-shaped crystal material transfer device is brought into basic contact with the surface of the plate-shaped crystal material to be transferred by the adsorption surface of the adsorption element. The position of each adsorption element is finely adjusted until the preset adsorption position of the plate-shaped crystal material to be transferred is reached. The preset adsorption position is set based on the flatness of the surface of the plate-shaped crystal material to be transferred and the range of motion of the adsorption element. Based on the thickness of the plate-shaped crystalline material to be transferred at the preset adsorption position, the maximum suction force that the preset adsorption position can withstand is obtained. Based on the maximum suction force, the adsorption force of the adsorption element is adjusted, and the plate-shaped crystal material to be transferred is attracted by the adsorption element. The lifting mechanism is used to lift the plate-shaped crystal material to be transferred; Move the plate-shaped crystal material transfer device to the position where the plate-shaped crystal material is to be placed; The in-situ rotating mechanism drives the adsorption mechanism to rotate until the plate-shaped crystal material adsorbed by the adsorption component is parallel to the position to be placed. The plate-shaped crystal material is slowly lowered by a lifting mechanism until it is placed in the desired position. The adsorption force is released, allowing the plate-shaped crystal material to detach from the adsorption component. The plate-shaped crystal material is then laid horizontally in the designated placement position, completing the transfer process.

2. The method for transporting plate-shaped crystal materials as described in claim 1, characterized in that, The specific process for determining the maximum suction force that the preset adsorption position can withstand, based on the thickness of the plate-shaped crystalline material to be transferred at the preset adsorption position, is as follows: The thickness of the plate-shaped crystal material to be transferred at the preset adsorption position is measured by an ultrasonic thickness gauge. Based on the following formula, the maximum suction force that the preset adsorption position can withstand is obtained: P=T 2 M / (1.1×r 2 ×S), Pmax=P 常 -P×6.895, Where P is the pressure difference between the two sides of the plate-shaped crystal material to be transferred at the preset adsorption position, in psi; T is the thickness of the plate-shaped crystal material to be transferred at the preset adsorption position, in mm; when the plate-shaped crystal material to be transferred is zinc sulfide, M=15000psi, and when the plate-shaped crystal material to be transferred is zinc selenide, M=8000psi; r is the radius of the force-bearing area of ​​the preset adsorption position of the plate-shaped crystal material to be transferred, that is, the radius of the adsorption area of ​​the adsorbent at the preset adsorption position of the plate-shaped crystal material to be transferred; S is a constant, S=4; Pmax is the maximum suction force that the preset adsorption position can withstand, that is, the absolute pressure, in kPa; P 常 At normal pressure, P 常 =101 kPa.
