Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of nonlinear crystal processing, and in particular is a device for removing large and fragile KDP / DKDP crystal blanks. Background Art
[0002] KDP (potassium dihydrogen phosphate) and DKDP (deuterated potassium dihydrogen phosphate) crystals are widely used in high-power laser systems, optical devices, and other fields due to their unique physical and chemical properties. However, these crystals often face challenges during growth, such as large size, heavy weight, and extreme brittleness. This makes their removal from the growth furnace and transfer to subsequent processing a technical challenge.
[0003] Existing methods often involve growing crystals directly on a crystal rack and then transferring them after growth is complete. However, this method has many drawbacks: First, due to the inherent brittleness and deliquescent nature of crystals, direct transfer can easily damage them. Second, the racks are often difficult to disassemble, and sawing the racks apart wastes a significant amount of material and can damage the crystals themselves. Furthermore, the smooth surface of crystals makes manual handling inefficient and carries the risk of crystal breakage or injury to transporters. Furthermore, contact with the crystals can also contaminate or damage the surface.
[0004] To solve the above problems, automated crystal removal devices are currently used. However, these devices often have problems such as complex structure, cumbersome operation, and poor adaptability. They are unable to meet the special needs of heavy, large, and easily damaged KDP and DKDP crystal blanks. Summary of the Invention
[0005] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a device for removing large and fragile KDP / DKDP crystal blanks, which can be adjusted according to the size of the crystal blanks, is easy to operate, and greatly improves the safety of removing the crystal blanks.
[0006] In order to achieve the above object, the technical solution adopted by the present invention is:
[0007] A device for removing large and fragile KDP / DKDP crystal blanks is characterized by comprising:
[0008] An adsorption mechanism for adsorbing and connecting the crystal blank includes at least three extra-thick rubber suction cups, a disc body, a biaxial connecting rod, a press buckle, and a handle; each of the extra-thick rubber suction cups is provided with a disc body, and two adjacent disc bodies are connected by the biaxial connecting rod, and each disc body is provided with a press buckle; the two ends of the handle are respectively fixed to any two disc bodies, and the extra-thick rubber suction cups are applied to the surface of the crystal blank, and the press buckles press the corresponding disc bodies, thereby forming a negative pressure between the extra-thick rubber suction cups and the crystal blank, achieving a firm fit between the crystal blank and the extra-thick rubber suction cups;
[0009] A support clamping mechanism for clamping the adsorption mechanism, comprising two parallel aluminum profiles, a connecting screw connecting the aluminum profiles, and a locking nut; the aluminum profile is used to place the handle, and both ends of the aluminum profile are provided with through holes for the connecting screws to pass through, which cooperate with the locking nut to clamp the adsorption mechanism;
[0010] The load-bearing adjustment mechanism is used to adjust the height of the support clamping mechanism, and includes four foot cups and adjustment nuts; the foot cups pass through the reserved holes on the aluminum profile and cooperate with the adjustment nuts to adjust the height of the aluminum profile.
[0011] Preferably, the biaxial connecting rod is connected to the disc body via threads, and the disc body is connected to the handle via a cylindrical pin.
[0012] Preferably, the buckle is made of engineering ABS material, the tray body is integrally formed of aluminum alloy, and the handle is made of aluminum alloy material.
[0013] Preferably, the load-bearing adjustment mechanism further includes a rubber pad sleeved on the bottom of the foot cup to prevent slipping.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1) This invention integrates multiple functional modules, including an adsorption mechanism, a support and clamping mechanism, and a load-bearing adjustment mechanism. These modules can be flexibly adjusted according to the size of the crystal blank, ensuring the safety and integrity of the crystal during removal and transfer. This allows for safe, efficient, and non-destructive removal and transfer of crystal blanks.
[0016] 2) The tight fit of the ultra-thick rubber suction cup and the engineered ABS buckle creates a stable negative pressure on the crystal blank surface, ensuring that the crystal will not slip or fall off during removal, greatly improving operational safety. Furthermore, the use of non-slip rubber pads further enhances friction between the device and the floor, preventing it from sliding or tipping over during operation.
[0017] 3) The support clamping mechanism, through the coordination of the aluminum profile, connecting screw, and locking nut, ensures that the adsorption mechanism maintains a stable posture during operation and is not shaken by external factors (such as vibration and impact). This stability not only improves operational accuracy but also reduces the risk of damage to the crystal blank during removal.
[0018] 4) The load-bearing adjustment mechanism allows the user to adjust the height and load capacity of the device according to actual needs. By rotating the adjustment nut, the aluminum profile can be easily moved up and down to accommodate crystal blanks of varying heights and weights. This design makes the device suitable for removing KDP and DKDP crystal blanks of various sizes.
[0019] 5) The present invention simplifies the operation steps and improves work efficiency. The operator only needs to perform simple operations to quickly and safely remove the crystal blank, which greatly saves time and labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described below with reference to the embodiments and drawings, but the scope of protection of the present invention should not be limited thereto.
[0026] See also Figure 1 , Figure 1 This is a front view of the overall structure of the device for removing large and fragile KDP / DKDP crystal blanks of the present invention. As shown in the figure, a device for removing large and fragile KDP / DKDP crystal blanks consists of an adsorption mechanism, a support and clamping mechanism, and a load-bearing adjustment mechanism.
[0027] Figure 2This is a schematic diagram of the suction mechanism of the present invention, which includes an extra-thick rubber suction cup 12, a biaxial connecting rod 9, an engineered ABS buckle 10, an integrally formed aluminum alloy plate 8, and an aluminum alloy handle 11. The extra-thick rubber suction cup 12 is connected to the engineered ABS buckle 10; the integrally formed aluminum alloy plate 8 is connected to the aluminum alloy handle 11 with a cylindrical pin; and the biaxial connecting rod 9 is threadedly connected to the integrally formed aluminum alloy plate 8.
[0028] The support and clamping mechanism includes an aluminum profile 2, a connecting screw 6, and a locking nut 5. The aluminum profile 2 and the connecting screw 6, as well as the connecting screw 6 and the locking nut 5, are both threadedly connected. The support and clamping mechanism supports the triangular circular suction cup aluminum alloy handle 11 through the aluminum profile 2. The connecting screw 6 passes through a reserved hole in the aluminum profile 2. Two locking nuts 5 are installed at both ends of the screw 6. The nuts 5 at both ends are tightened toward the aluminum profile 2 until the nuts 5 lock the aluminum profile 2, allowing the support and clamping mechanism to support the aluminum alloy handle 11 and clamp the aluminum profile 2.
[0029] The load-bearing adjustment mechanism includes a foot cup 7 and an adjusting nut 4. The foot cup 7 and the adjusting nut 4 are threadedly connected. The foot cup 7 passes through the reserved hole of the aluminum profile. The adjusting nut 4 supports the aluminum profile 2. The adjusting nut 4 is rotated with an open-end wrench to allow the aluminum profile 2 to move up and down.
[0030] The present invention utilizes the strong adsorption force of the suction cup to adsorb both sides of the crystal. When the suction cups on both sides are firmly adsorbed on the crystal, the buckle is pressed to push the aluminum profile against the lower end surface of the suction cup handles on both sides (which can bear force). The aluminum profiles on both sides are reserved with two long screws, and the nuts on both sides of the screws are locked to tighten the gap between the aluminum profile and the suction cups. Holes are reserved at both ends of the aluminum profile, and integrated screw foot cups (4) are installed to increase the height of the aluminum profile so that the crystal can leave the crystal frame plate. When tightening the adjustment screws of the foot cups, 4 people are required to simultaneously tighten the nuts clockwise for the same number of turns to lift the crystal safely and steadily. By visual observation, the crystal moves upward, the crystal frame plate 3 is removed, and the crystal trolley is placed under the lifted crystal. A clean rubber pad is placed on the crystal trolley. Because the crystal trolley is made of aluminum alloy, the crystal cannot directly contact it. The adjustment nut is slowly rotated in the opposite direction to allow the crystal to steadily descend to the crystal trolley padded with the rubber pad.
[0031] The above-mentioned specific implementation can be partially adjusted in different ways by those skilled in the art without departing from the principles and purpose of the present invention. The scope of protection of the present invention shall be based on the claims and shall not be limited by the above-mentioned specific implementation. All implementation schemes within its scope shall be subject to the constraints of the present invention.
