Description

Technical Field

[0001] The invention belongs to the technical field of nonlinear crystal processing, and in particular is a device for taking out large-scale vulnerable 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 of large size, heavy weight and high brittleness during the growth process, making it a technical challenge to remove them from the growth furnace and transfer them to subsequent processing links.

[0003] Most existing methods use the method of directly growing crystals on a crystal rack and transferring them after the growth is completed. However, this method has many shortcomings: first, due to the brittleness and deliquescent nature of the crystal itself, it is very easy to damage the crystal during direct transfer; second, it is often difficult to disassemble the crystal rack from the crystal. If the crystal rack is sawed, it will not only waste a lot of materials, but also may damage the crystal itself; third, the crystal surface is smooth, and manual handling is not only inefficient, but also has the risk of crystal breaking or injury to the handler, and contact by people may also cause contamination or damage to the crystal surface.

[0004] In order to solve the above problems, automated crystal removal devices are currently used, but these devices often have problems such as complex structure, cumbersome operation, and poor adaptability, and are difficult to meet the special needs of heavy, large-sized 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 vulnerable KDP / DKDP crystal blanks is characterized by comprising:

[0008] The adsorption mechanism is used for adsorption and connection of the crystal blank, and comprises at least three super-thick rubber suction cups, a disc body, a biaxial connecting rod and a buckle, and a handle; each of the super-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 buckle; the two ends of the handle are respectively fixed on any two disc bodies, and the super-thick rubber suction cup is attached to the surface of the crystal blank, and the buckle presses the corresponding disc body, thereby forming a negative pressure between the super-thick rubber suction cup and the crystal blank, so as to achieve a firm attachment of the crystal blank to the super-thick rubber suction cup;

[0009] A support clamping mechanism, used for clamping the adsorption mechanism, comprising two parallel aluminum profiles, a connecting screw and a locking nut connecting the aluminum profiles; the aluminum profile is used to place the handle, and both ends of the aluminum profile are provided with through holes for the connecting screw 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 supporting clamping mechanism, and includes four foot cups and an adjusting nut; the foot cups pass through the reserved holes on the aluminum profile and cooperate with the adjusting nut 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 comprises a rubber pad sleeved on the bottom of the foot cup for anti-slipping.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1) The present invention integrates multiple functional modules such as adsorption mechanism, support clamping mechanism, load-bearing adjustment mechanism, etc., which can be flexibly adjusted according to the size of the crystal blank to ensure the safety and integrity of the crystal during the removal and transfer process. It realizes safe, efficient and non-destructive removal and transfer of the crystal blank.

[0016] 2) Through the close cooperation between the ultra-thick rubber suction cup and the engineering ABS buckle, a stable negative pressure can be formed on the surface of the crystal blank, ensuring that the crystal will not slip or fall off suddenly during the removal process, greatly improving the safety of the operation. At the same time, the application of anti-slip rubber pads also further enhances the friction between the device and the ground, preventing the device from sliding or tipping over during operation.

[0017] 3) The support clamping mechanism, through the cooperation of aluminum profiles, connecting screws and locking nuts, ensures that the adsorption mechanism can maintain a stable posture during operation and will not shake due to external factors (such as vibration, impact, etc.). This stability not only improves the accuracy of the operation, but also reduces the risk of damage to the crystal blank during the removal process.

[0018] 4) The design of the load-bearing adjustment mechanism allows the user to adjust the height and load-bearing 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 different heights and weights. This design makes the device widely used in the removal of KDP and DKDP crystal blanks of various sizes.

[0019] 5) The present invention simplifies the operation steps and improves the 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 in conjunction with embodiments and drawings, but the protection scope 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 is composed of an adsorption mechanism, a supporting clamping mechanism, and a load-bearing adjustment mechanism.

[0027] Figure 2Schematic diagram of the adsorption mechanism in the present invention, the adsorption mechanism includes an ultra-thick rubber suction cup 12, a biaxial connecting rod 9, an engineering ABS buckle 10, an integrally formed aluminum alloy plate 8 and an aluminum alloy handle 11. The ultra-thick rubber suction cup 12 is connected to the engineering ABS buckle 10; the integrally formed aluminum alloy plate 8 is connected to the aluminum alloy handle 11 by a cylindrical pin; the biaxial connecting rod 9 is connected to the integrally formed aluminum alloy plate 8 by a thread.

[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 all threadedly connected; the support and clamping mechanism supports the triangular round suction cup aluminum alloy handle 11 through the aluminum profile 2, the connecting screw 6 passes through the reserved hole of the aluminum profile 2, and two locking nuts 5 are installed at both ends of the screw 6, and the nuts 5 at both ends are locked toward the aluminum profile 2 until the nuts 5 lock the aluminum profile 2, so that the support and clamping mechanism supports the aluminum alloy handle 11 and clamps the aluminum profile 2;

[0029] The load-bearing adjustment mechanism includes a foot cup 7 and an adjustment nut 4. The foot cup 7 and the adjustment nut 4 are threadedly connected, the foot cup 7 passes through a reserved hole in the aluminum profile, the adjustment nut 4 supports the aluminum profile 2, and the adjustment 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 stably 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), and two long screws are used to connect the reserved holes of the aluminum profiles on both sides, 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. Through visual observation, the crystal moves upward, and the crystal frame plate 3 is removed. The crystal trolley is placed under the lifted crystal, and 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 with the rubber pad padded.

[0031] The above-mentioned specific implementation can be partially adjusted in different ways by those skilled in the art without departing from the principle and purpose of the present invention. The protection scope of the present invention shall be based on the claims and shall not be limited by the above-mentioned specific implementation. Each implementation scheme within its scope shall be subject to the constraints of the present invention.
