Description

Technical Field

[0001] This utility model relates to the field of optoelectronic crystal processing technology, and in particular to an optoelectronic crystal orientation cutting and positioning device. Background Technology

[0002] Due to their unique physical properties, optoelectronic crystals have wide applications in optical communication, laser equipment, and sensor manufacturing. In the production and processing of optoelectronic crystals, cutting them into thin slices that meet specific size and crystal orientation requirements is a crucial step.

[0003] Traditional crystal cutting and positioning equipment typically uses a simple lead screw and nut mechanism or a common cylinder for unidirectional or mechanical bidirectional clamping during operation. This purely rigid clamping method can fix the crystal in a static state, but after the laser cutting equipment is started, the high-speed reciprocating motion of the processing head and environmental resonance will generate continuous high-frequency vibrations.

[0004] These high-frequency vibrations are transmitted directly to the clamping jaws through the worktable. Because the rigid clamping structure lacks the ability to buffer and absorb minute vibrations, stress fatigue and loosening can easily occur between the clamping jaws and the crystal contact surface after a long period of cutting. This can lead to minute displacement of the crystal, which can not only severely damage the orientation cutting accuracy of the optoelectronic crystal, but also easily scratch the crystal surface during loosening and friction.

[0005] Therefore, this utility model proposes a photoelectric crystal orientation cutting and positioning device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a photoelectric crystal orientation cutting and positioning device, which aims to improve the problems of existing photoelectric crystal orientation cutting and positioning devices, such as the lack of elastic buffering in the clamping structure leading to easy displacement of the workpiece under cutting vibration, and the rigid clamping being prone to wear on the crystal surface and low fitting degree for irregular shapes.

[0007] To achieve the above objectives, this utility model provides a photoelectric crystal orientation cutting and positioning device, comprising: a protective shell, a rotating cover, a laser cutting device, a support base, a support plate, a fixed plate, a sliding column, a sliding plate, a slide rail, and a damper.

[0008] The damper has a tubular structure that provides nonlinear elastic buffering and reset potential energy.

[0009] Furthermore, the fixed plate, the sliding plate, and the damper are combined by means of one end being fixedly connected to the outer wall of the fixed plate and the other end being fixedly connected to the outer wall of the sliding plate, and both ends being fixed between the two sliding plates respectively.

[0010] Preferably, the top of the sliding plate has a sliding block and a protective soft block fixedly connected to the outer wall of the sliding block, and the connection between the sliding plate and the sliding block is a modular disassembly connection through a fixed screw.

[0011] Preferably, the optoelectronic crystal orientation cutting and positioning device further includes a reinforcement component, which is disposed above the support plate and is used to provide multi-angle adaptive surface contact locking in the vertical direction.

[0012] Preferably, the reinforcement component has a sliding frame fixedly connected above the support plate, a friction strip fixedly connected to the outer wall of the sliding frame, and a shifting block slidably connected to the outer walls of the sliding frame and the friction strip.

[0013] Preferably, the reinforcement component has a connecting frame and an extension column, the two transposition blocks are connected by the connecting frame, and the outer wall of the connecting frame is fixedly connected to the extension column.

[0014] Preferably, the reinforcement component has a flexible plate and a swivel ball, the inside of the extension column is hinged to the swivel ball, and the outer wall of the swivel ball is fixedly connected to the flexible plate to achieve multi-angle adaptive adjustment of the contact surface.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by sliding the sliding plate to the outer wall of the sliding column and the slide rail and installing three dampers for bidirectional elastic contact, the problem of insufficient positioning stiffness and easy displacement of the clamping mechanism under high-frequency cutting vibration in the prior art is solved, and the technical effect of high-precision dynamic anti-vibration centering positioning is achieved.

[0016] 2. This utility model solves the problem that rigid clamps in the prior art are prone to wear on the surface of photoelectric crystals and the replacement of consumables is cumbersome by using a fixing screw to detachably install a sliding block with a protective soft block at the top of the sliding plate, thereby achieving the technical effect of non-destructive clamping and rapid maintenance.

[0017] 3. This utility model solves the problem in the prior art that it is impossible to adaptively lock irregular crystal surfaces at multiple angles by setting a displacement block in the reinforcement component in conjunction with a friction strip and using an extension column to hinge the universal ball and the flexible plate. It achieves the technical effect of multi-dimensional adaptive bonding and improved clamping firmness. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-7 This utility model provides a photoelectric crystal orientation cutting and positioning device, which aims to solve the problems in the prior art where photoelectric crystals are prone to slight displacement under high-frequency cutting vibration conditions and have insufficient centering and positioning stiffness.

[0022] The optoelectronic crystal orientation cutting and positioning device includes a protective shell 1 and a rotating cover 2 hinged to the outer wall of the protective shell 1. Inside the protective shell 1, a laser cutting device 3 for processing and a positioning component 4 for clamping reference are fixedly connected. The positioning component 4 includes a support base 402 and a support plate 401 fixedly connected to the top of the support base 402. The support base 402 serves as the load-bearing foundation structure of the overall processing platform. A fixed plate 403 is fixedly connected above the support base 402. A sliding column 404 serving as the linear guide foundation is fixedly connected to the outer wall of the fixed plate 403. At the same time, a slide rail 407 is fixedly connected inside the support plate 401. The sliding plate 406, as the main moving end, is synchronously slidably connected to the outer wall of the sliding column 404 and the slide rail 407, thereby constructing a basic positioning platform architecture with high-strength linear anti-deflection guidance capability.

[0023] The positioning component 4 also includes three dampers 405 sleeved on the outer wall of the sliding column 404. These three dampers 405 constitute the elastic potential energy and shock absorption center of the entire centering and clamping mechanism. One end of two dampers 405 is firmly fixed to the outer wall of the fixed plate 403, and the other end of the two dampers 405 is directly fixed to the outer wall of the sliding plate 406, thus forming a basic bidirectional elastic traction and limiting circuit. At the same time, the two ends of the other damper 405 are respectively fixed to the inner walls of the two sliding plates 406. This unique double-pull and one-push or multi-combination buffer structure allows the sliding plate 406 to obtain nonlinear damping force feedback and elastic reset support when it moves linearly back and forth on the sliding column 404 and the slide rail 407. This greatly eliminates the mechanical gap and vibration amplification effect caused by relying solely on rigid slide rails, ensuring that the sliding plate 406 can provide a stable and lasting flexible clamping force when clamping the photoelectric crystal, effectively avoiding the workpiece loosening caused by the micro-vibration transmitted by the laser cutting device 3 during high-frequency operation.

[0024] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to prevent the clamping mechanism from directly contacting and scratching the expensive and fragile photoelectric crystal surface, a protective component 5 is connected to the top of the sliding plate 406. The protective component 5 includes a sliding block 501 and a protective soft block 502 fixedly connected to the outer wall of the sliding block 501. The top of the sliding plate 406 is modularly and detachably connected to the sliding block 501 by a fixing screw 503. The fixing screw 503 is rotatably inserted inside the sliding plate 406 and the sliding block 501. This structure allows the operator to quickly unscrew the fixing screw 503 to replace the consumable when the protective soft block 502 is worn or aged without disassembling the entire positioning base.

[0025] As another preferred embodiment, in order to provide absolute rigidity locking in the vertical direction after centering and positioning, an independently operating reinforcing component 6 is provided above the support plate 401. The reinforcing component 6 includes a sliding frame 601 fixedly connected above the support plate 401 and a friction strip 602 fixedly connected to the outer wall of the sliding frame 601. Two shifting blocks 603 are symmetrically slidably connected to the outer walls of the sliding frame 601 and the friction strip 602. The two shifting blocks 603 are connected by a connecting frame 604 to form a bridge-type cross-connection structure. The high static friction coefficient provided by the friction strip 602 ensures that the shifting blocks 603 will not retract after a lateral force is applied.

[0026] As a further preferred embodiment, in order to meet the surface bonding requirements of different facet angles and irregularly shaped optoelectronic crystals, the outer wall of the connecting frame 604 is fixedly connected to a downwardly extending extension column 607. The extension column 607 is fitted and hinged with a universal ball 606. The outer wall of the universal ball 606 is fixedly connected to a flexible plate 605 made of flexible material. The universal rotational freedom of the universal ball 606 allows the flexible plate 605 to automatically adapt to the angle and deflect when it comes into contact with the irregular outer surface of the crystal, thus completing the adaptive bonding surface conversion, thereby converting point contact or line contact into surface contact, further improving the clamping stability.

[0027] Working principle: When the photoelectric crystal needs to be cut, the operator first pulls the sliding block 501 in the protective component 5 outward to place the photoelectric crystal to be processed between the two protective soft blocks 502. After releasing, under the combined action of the reset potential energy built into the three dampers 405, the sliding plate 406 smoothly retracts along the sliding column 404 and the slide rail 407, accurately clamping and positioning the photoelectric crystal at the center reference position of the support plate 401. The flexible material of the protective soft block 502 absorbs the rigid impact, thereby avoiding damage to the outer wall of the crystal. Then, the operator moves the two connecting brackets 604 in the reinforcing component 6 inward together. The lateral sliding mechanism drives the shifting block 603 to overcome friction on the outer walls of the sliding frame 601 and the friction strip 602. When the flexible plate 605 contacts the photoelectric crystal, the universal ball 606 rotates freely inside the extension column 607 to adjust its posture, so that the flexible plate 605 is fully adaptive and tightly attached to the upper and lower outer walls of the photoelectric crystal. The static friction locking force formed between the shifting block 603 and the friction strip 602 maintains the clamping state. After completing the multi-dimensional limiting reinforcement, the rotating cover 2 is closed and the laser cutting device 3 inside the protective shell 1 is started to perform high-precision cutting on the photoelectric crystal, which is in an absolutely static and shock-absorbing protection state.
