Description

Technical Field

[0001] The present invention belongs to the technical field of optical prism processing, and in particular relates to an optical prism processing device and a processing method thereof. Background Art

[0002] Prism: A transparent object formed by two intersecting, non-parallel planes, used to split or disperse light beams. It is widely used in the field of optics and can be divided into many types according to its properties and uses. The most commonly used is the equilateral prism.

[0003] The processing technology of optical prism mainly includes: grinding, polishing and coating steps:

[0004] Grinding: The prism is cut into the desired shape by a grinding machine, and the surface is ground to the specified accuracy and finish.

[0005] Polishing: The ground prism is further polished to achieve higher optical quality. Therefore, it is necessary to choose appropriate polishing materials and tools, such as copper or glass powder;

[0006] Whether it is grinding or polishing, the clamping stability of the fixture is an important basis for affecting the grinding and polishing accuracy. However, the traditional optical prism fixing process is that the operator only uses glue to stick the optical prism to the glass body, and then uses a single polishing machine to grind and polish the end face of the optical prism. The aforementioned method of fixing the optical prism is not only cumbersome (glue dispensing-glue pressing-degumming-glue washing), but also has a low degree of batch production, low efficiency of a single machine, and high labor costs. In addition, there is also the phenomenon of unstable optical prism positioning caused by the difference in manual glue dispensing, and then there is a problem of nonlinear coordination between external vibration factors and the productive vibration of the grinder or polisher itself, that is, the shear force between the two is destroyed, and the filling distribution of abrasive particles on the cutting surface depressions and defects during shearing increases the probability of burrs and patterns, and even changes the distribution of cutting force, causing cutting deformation on the material surface, reducing the quality of grinding and polishing.

[0007] In addition, the traditional dispensing method inevitably requires the operator to manually place the prism. On the one hand, this further increases the operator's labor intensity, increases the prism placement deviation rate, reduces the later fixing accuracy, and lowers the product yield; on the other hand, it further reduces the output of a single machine and affects the efficiency of optical prism processing.

[0057] A method for blanking and fixing an optical prism, using the above-mentioned optical prism processing device to implement blanking and fixing of the optical prism, the specific steps are as follows:

[0058] S1: First, the top closing ring is used to guide the rotation of the buckle ring. During this process, the position of the optical prism in the tube is adjusted by the dial pin. After that, the short-circuit plate is driven to move by the telescopic cylinder, and then the mouth frame drives the segmented plate to reciprocate, finally realizing the alternating unloading of the optical prism in the tube by the upper and lower plates;

[0059] S2: The optical prism is then guided and supported by the rubber plate and the fixture during discharge. The rotation of the cam causes the optical prism to tilt only toward the leaf plate. The leaf plate and the damping plate reduce the kinetic energy of the optical prism when it slides down, ensuring the placement integrity of the optical prism.

[0060] S2: Finally, the inner gear drives the outer gear to rotate. When the outer gear rotates, the rack synchronously drives the Z panel under the dual support and guidance of the turntable and the right-angle frame, controlling the outer frame, middle frame, inner frame and end plate to move toward the optical prism until the movable column, under the guidance of the right-angle frame, controls the corner pad to implement equal force clamping on the optical prism at different positions.

[0061] The present invention has the following beneficial effects:

[0062] 1. The present invention causes the outer frame to control the middle plate and the inner plate through the sliding of the Z panel between the turntable and the right-angle frame, driving the end plate to squeeze the movable column until the corner pad contacts the optical prism in the fixture. In this process, the multi-stage connection between the ball head and different end plates breaks the singleness of the alignment between the traditional multi-camera elastic clamp and the clamped object, and can achieve stable clamping of multi-cameras with the same specifications and corresponding special shapes, avoid the problem of different clamping forces between multiple clamping units, help improve clamping accuracy, reduce the nonlinear coordination between external vibration factors and the productive vibration of the grinder or polisher itself, fully ensure the idealization and expectation of the shear force between the two, improve the processing smoothness of the prism, and at the same time create conditions for mass production, improve the output of a single machine, and increase the efficiency of grinding and polishing.

[0063] 2. The present invention controls the mouth frame to drive the segmented plate to reciprocate under the telescopic action of the telescopic cylinder through the short-circuit plate, thereby realizing the staggered reception of the optical prism by the upper plate and the lower plate, that is, realizing the intermittent blanking of the optical prism inside the placement tube. At the same time, the buckle is guided by the top closing ring to control the column and the plate to drive the pin to rotate along the inner wall of the placement tube until the optical prism in the placement tube is moved to the specified position, fully ensuring the discharge consistency, stability and long-term effectiveness of the optical prism.

[0064] 3. The present invention guides and reduces the energy of the optical prism during the discharge process by using a rubber plate that is tangent to the inner wall of the placement cylinder. On the one hand, it improves the alignment accuracy between the optical prism and the V-shaped groove of the fixture. On the other hand, it reduces the probability of damage to the optical prism due to the impact of gravitational potential energy. During this process, the cam in the rotating state is used to control the fully discharged optical prism to tilt toward the page plate until the optical prism is engaged with the V-shaped groove inside the fixture. After that, the page plate, under the action of the torsion spring, cooperates with the damping plate to perform further energy reduction treatment on the optical prism when it slides, thereby avoiding the damage rate of the optical prism and the fixture.

[0088] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0089] It should be noted that the terms “vertical”, “horizontal”, “left”, “right” and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0090] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0091] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 11 It can be seen that an optical prism processing device and a processing method thereof include a counter 1, an adjustment unit 2 is provided at both ends of the counter 1, a blanking unit 3 is provided on one side of the adjustment unit 2, a control unit 4 is provided at the middle position of the top of the counter 1, and a clamping unit 5 is evenly provided on one side of the control unit 4;

[0092] Reference Figure 1It can be seen that a side guardrail 11 is plug-in-installed on the top of the counter 1 to protect the adjustment unit 2, the blanking unit 3 and the clamping unit 5. An observation window 12 is symmetrically snap-fitted on the end of the side guardrail 11 away from the counter 1.

[0093] Reference Figure 2 、 Figure 3 and Figure 6 It can be seen that the adjustment unit 2 includes: two pedestals 21, which are symmetrically mounted on both ends of the end surface of the counter 1 close to the side guardrail 11; a hydraulic rod 22, which is detachably mounted on the middle position of the end surface of the pedestal 21 away from the counter 1 by bolts; a cross-section plate 23, which is plug-in mounted on the end of the two hydraulic rods 22 away from the pedestal 21; a transverse axis platform 24, which is slidably mounted on the side of the transverse plate 23 close to the observation window 12; and a joint seat 25, which is slidably mounted on the side of the transverse axis platform 24 close to the observation window 12.

[0094] The longitudinal axis platform 26 is snap-fitted and installed in the middle position of the end face of the joint seat 25 on the side close to the observation window 12; there are at least three placement tubes 27, which are plugged into an array and installed on the end face of the longitudinal axis platform 26 on the side close to the observation window 12; there are four strips 28, two by two in a group, which are symmetrically snap-fitted and installed at both ends of the placement tubes 27 to limit and maintain the stability of multiple placement tubes 27 between the longitudinal axis platform 26; the mouth ring 29 is snap-fitted and installed on the outer walls of two adjacent placement tubes 27, and the mouth ring 29 is plug-fitted and installed with the two strips 28 on the end away from the longitudinal axis platform 26.

[0095] Counter 1, side guardrail 11 and observation window 12: The overall adjustment of the counter 1, the adjustment unit 2, the blanking unit 3, the control unit 4 and the clamping unit 5, and the coordination between the operator are convenient for operation and maintenance, as well as for transfer or transportation;

[0096] During this process, the side guardrail 11 is used to implement partition protection for the adjustment unit 2, the blanking unit 3, the control unit 4 and the clamping unit 5, thereby reducing the interference and damage of external factors to the aforementioned units to a certain extent;

[0097] The counter 1 is combined with the observation window 12 to improve the operator's experience of use. On the one hand, it is convenient for the operator to observe and understand the linkage and coordination between the aforementioned units in real time; on the other hand, it is better to observe each processing process of the optical prism, respond to unexpected problems in time, and avoid production safety accidents.

[0098] The principle process of the movement trajectory of the placement cylinder 27 is explained (i.e. the three-axis linkage motion trajectory of the X, Y and Z axes):

[0099] The longitudinal running process of the placement cylinder 27 (based on the direction from the side guardrail 11 to the counter 1 - Z axis):

[0100] The hydraulic rod 22, supported by the pedestal 21, controls the reciprocating motion of the cross-plate 23 through its own telescopic action. At this time, the joint seat 25, under the control of the horizontal axis platform 24, drives the vertical axis platform 26 and the placement cylinder 27 to reciprocate synchronously.

[0101] The horizontal movement process of the placement cylinder 27 (based on the length direction of the cross-section plate 23 - Y axis):

[0102] The horizontal axis platform 24 drives the joint seat 25 to reciprocate under the guidance and support of the cross-section plate 23. In specific implementation, the horizontal axis platform 24 can be driven by an electric slider to move, and then the vertical axis platform 26 is driven by the joint seat 25 to control the placement cylinder 27 to synchronously make horizontal reciprocating motion;

[0103] The horizontal movement process of the placement cylinder 27 (based on the length direction of the horizontal axis platform 24 and perpendicular to the horizontal movement direction of the placement cylinder 27 - X axis):

[0104] Under the support and guidance of the horizontal axis platform 24, the joint seat 25 controls the vertical axis platform 26 to drive the placement cylinder 27 to perform horizontal reciprocating motion;

[0105] The above are the specific implementation steps of the three-axis running trajectory of the placement cylinder 27;

[0106] Strips 28 and mouth rings 29: Four mutually symmetrical strips 28 are used to strengthen the connection stability between adjacent distributed placement tubes 27. At the same time, the mouth rings 29 further enhance the connection strength between adjacent placement tubes 27, fully ensuring the uniformity of the axis of the placement tubes 27, improving the smoothness of the falling of the optical prism, and thus ensuring the long-term continuity and stability of the discharge.

The width of the vertical section of the T-shaped plate 32 is greater than the diagonal length of the optical prism to be processed, that is, the staggered spacing between the upper plate 33 and the lower plate 34 is greater than the diagonal length of the optical prism to be processed. In addition, the vertical distance between the upper plate 33 and the lower plate 34 is consistent with the length of the optical prism, and there is an intersection between the maximum radius area of ​​rotation of the cam 319 and the axis of the placement tube 27.

[0113] Hereby, it is explained that the external optical prism falls toward the placement tube 27 (this is only one embodiment as an example, and it should be understood that other embodiments with the same principle are also within the scope of protection of the present invention);

[0114] Example (see attached Figure 10 ):

[0116] In addition, Figure 10 The middle 1-1 area represents the covering of the sheet 38 directly below it by the external conveying mechanism, so as to avoid collision and limitation between the sheet 38 when the optical prism falls, and ensure that the optical prism falls smoothly into the placement tube 27.

[0117] The falling process of an optical prism (one) inside the placement tube 27 (all placement tubes 27 in the direction from the side guardrail 11 to the counter 1):

[0118] When the optical prism (see attached Figure 7 A1) falls from the 1-a placement tube 27 to the 1-c placement tube 27 (for details, please refer to the attached Figure 4 ):

[0119] First, the buckle 36, under the support and guidance of the top closing ring 35, controls the upright column 37 to drive the plate 38 under the guidance of the placement tube 27, prompting the dial pin 39 to slide on the inner wall of the placement tube 27 (1-a). During this process, the dial pin 39 adjusts the position of the optical prism in the placement tube 27 (1-a) until the end of the optical prism aa is engaged or aligned with the groove at bb inside the placement tube 27 (the position identity of the optical prism after unification, aa and bb can be referred to the attached Figure 7 and attached Figure 10 ), in specific implementation, the buckle 36 can be driven to rotate by electric sliding;

[0120] Next, the optical prism in the placement tube 27 is supported by the upper plate 33 (the center point of the upper plate 33 in the initial state coincides with the axis of the placement tube 27). At this time, the vertical distance between the center point of the lower plate 34 and the axis of the placement tube 27 is consistent with the diagonal length of the optical prism.

[0121] Finally, the short-circuit plate 322, under the telescopic action of the telescopic cylinder 323, controls the opening frame 321 to synchronously drive the segmented plates 31 at different positions to perform synchronous reciprocating motion (and the single running distance of the segmented plates 31 is consistent with the vertical distance from the center point of the upper plate 33 to the center point of the lower plate 34);

[0122] During this process, the center point of the upper plate 33 withdraws from the axis of the placement tube 27 to the section of the placement tube 27 close to the groove frame 321 (when the upper plate 33 moves, the optical prism on it and the inner wall of the placement tube 27 move relative to each other until the optical prism is completely separated from the upper plate 33. In the specific implementation, the end of the upper plate 33 away from the groove frame 321 is chamfered). At this time, the center point of the lower plate 34 moves from the section of the placement tube 27 away from the groove frame 321 to the axis of the placement tube 27. At the same time, the optical prism falls from the upper plate 33 to the lower plate 34 under the action of gravity (the width of the vertical section of the T-joint 32 is greater than the diagonal length of the optical prism to be processed, that is, the staggered distance between the upper plate 33 and the lower plate 34 is greater than the diagonal length of the optical prism to be processed);

[0123] When the center point of the upper plate 33 moves toward the axis of the placement tube 27 again under the control of the T-plate 32, the upper plate 33 just cuts into the space between the previous optical prism and the next optical prism. Similarly, the center point of the lower plate 34 moves away from the axis of the placement tube 27 (the optical prism moves relative to the lower plate 34 under the action of the inner wall of the placement tube 27), until the current optical prism falls into the placement tube 27 at position 1-b (the principle of the optical prism falling from 1-b to the placement tube 27 at position 1-c is the same as the principle of the placement tube 27 from 1-a to 1-b).

[0124] The above is the process of intermittently discharging the optical prism from the inside of the placement tube 27 to the outside (for details, please refer to the attached Figure 8 );

[0125] The optical prism is placed in the tube 27 at 1-c and the material is discharged:

[0126] First, when the optical prism falls from the bottom of the placement tube 27 at position 1-c toward the receiving end surface (clamp 581), the bottom surface of the rubber plate 313 first contacts the receiving end surface. Thereafter, the optical prism falls smoothly toward the receiving end surface under the dual effects of the energy reduction of the damping plate 317 and the guidance of the two opposite rubber plates 313 (the vertical distance between the two rubber plates 313 is equal to the length of the V-shaped groove opening).

[0127] Next, the placement cylinder 27 moves in the Z-axis direction under the action of the aforementioned hydraulic cylinder until the optical prism is completely separated from the placement cylinder 27;

[0128] Finally, the cam 319 is driven to rotate by the connecting pin 318. After the raised end of the cam 319 rotates a certain angle (the maximum radius of rotation of the cam 319 intersects with the axis of the placement cylinder 27), it provides a force for the optical prisms that have been separated from the placement cylinder 27 to fall to the end of the leaf plate 315 (unifying the sliding direction of the optical prisms during discharge, thereby ensuring the final uniformity of the placement of the optical prisms).

[0129] During this process, a restoring force is provided to the page plate 315 by the torsion spring 316 (in specific implementation, the compatibility between the length of the page plate 315 and the width of the rubber plate 313 is controlled, that is, the length of the page plate 315 is at most one centimeter less than the width of the rubber plate 313, to prevent the optical prism from being too high from the height between the optical prism and the supporting end face when the optical prism detaches from the page plate 315, resulting in excessive gravitational potential energy) (the elastic properties of the torsion spring 316 itself help absorb the instantaneous kinetic energy of the optical prism sliding down, and at the same time, the page plate 315 can increase the friction force of the optical prism sliding down, further offsetting the kinetic energy of the tipping). This ensures that the page plate 315 reduces the energy of the optical prism when it slides down, thereby reducing the damage rate of the optical prism. Similarly, the damping plate 317 also reduces the kinetic energy of the optical prism sliding down, protecting its end face integrity.

[0130] Reference Figure 2 、 Figure 12 and Figure 14 As can be seen, the clamping unit 5 includes: Z panels 51, two of which form a group and are symmetrically distributed in the space on one side of the top of the counter 1; an outer frame 52, which is plug-in mounted on the vertical section of the Z panel 51 away from the counter 1 via a connecting shaft; a middle frame 53, which is rotatably mounted on the vertical section on one side of the outer frame 52 via a rotating shaft; an inner frame 54, which is rotatably mounted on the vertical section on the other side of the outer frame 52 via a rotating shaft, and is interlaced and fitted with the middle frame 53; end plates 55, which are rotatably mounted on the vertical sections on both sides of the middle frame 53 and the inner frame 54 via a rotating shaft, and the end plates 55 have at least one joint end, that is, the length of the end plates 55 is variable.

[0131] The ball head 56 is hingedly mounted on the end surface of the end plate 55 away from the Z panel 51, and the number of ball heads 56 installed corresponds to the number of joint ends of the end plate 55; the movable column 57 is ball-hinged at the end of the ball head 56 away from the inner frame 54; the corner bracket 58 has an L-shaped cross-section and is plugged into the vertical section of the Z panel 51 away from the counter 1, and is slidably mounted with the movable column 57; the corner pad 59 has an L-shaped cross-section and is snap-fitted onto the end of the movable column 57 away from the end plate 55;

[0132] Reference Figure 7 and Figure 14 It can be seen that a clamp 581 is provided between the two Z panels 51 facing each other, and a V-shaped groove is uniformly formed on the end surface of the clamp 581 away from the counter 1. A slot 582 is uniformly formed on the end surface of the clamp 581 facing the movable column 57, which matches the corner pad 59. The opening size of the slot 582 is one unit larger than the cross-sectional area of ​​the horizontal section of the corner pad 59. A ring piece 583 is slidably mounted on the outer wall of the end of the movable column 57 close to the clamp 581 and is clamped to the corner bracket 58. A ring piece 583 is also fixedly mounted on the outer wall of the end of the movable column 57 away from the clamp 581. A shock-absorbing spring 584 is fixedly mounted between the two ring pieces 583 and is sleeved with the movable column 57.

[0133] Reference Figure 2 、 Figure 11 、 Figure 12 and Figure 13 As can be seen, the control unit 4 includes: a turntable 41, which is rotatably mounted in the middle position of the end of the counter 1 close to the side guardrail 11; a plug-in post 42, which is rotatably mounted at the axis of the turntable 41; an internal gear 43, which is fixedly mounted on the outer wall of the plug-in post 42 on the side away from the side guardrail 11; vertical rods 44, which are evenly distributed circumferentially inside and outside the turntable 41, and the vertical rods 44 are snap-fitted and mounted with the turntable 41. In addition, the end of the vertical rod 44 away from the counter 1 is snap-fitted and mounted with the clamp 581; an external gear 45, which is rotatably mounted on the outer wall of the vertical rod 44 and meshes with the internal gear 43, and the thickness of the external gear 45 is twice the thickness of the internal gear 43;

[0134] The low closing chamber 46 is fixedly installed inside the turntable 41 through a mounting plate, and the vertical distance between the low closing chamber 46 and the internal gear 43 is five centimeters; the right-angle frame 47 is symmetrically clamped and installed at both ends of the low closing chamber 46, and the Z panel 51 is slidingly clamped and installed with the right-angle frame 47, and is also slidingly mounted with the end face of the turntable 41 away from the counter 1; the rack 48 is slidingly clamped and installed on the horizontal section of the right-angle frame 47, and the rack 48 is fixedly connected to the vertical section of the Z panel 51 close to the counter 1. In addition, the rack 48 is engaged with the external gear 45.

[0135] The specific process of the Z panel 51 moving toward each other is as follows:

[0136] Under the control of the engagement post 42, the internal gear 43 engages with the external gear 45 at a different position. Specifically, the engagement post 42 can be driven to rotate by an external motor. Thereafter, two centrally symmetrical racks 48 (with the axis of the internal gear 43 as the base point) are engaged with the external gear 45 to drive the Z panel 51 to move toward each other (the opposite movement principle is the opposite) under the dual guidance and support of the turntable 41 and the right-angle bracket 47.

[0137] The vertical distance between the lower closing chamber 46 and the inner gear 43 is five centimeters. The purpose is to prevent the lower closing chamber 46 and the inner gear 43 from colliding and limiting when the turntable 41 rotates intermittently as a whole. At the same time, the lower closing chamber 46 and the turntable 41 are connected by the mounting plate to provide a stable installation environment and support for the right-angle frame 47.

[0138] The thickness of the outer gear 45 is twice that of the inner gear 43. The purpose is to achieve meshing between the outer gear 45 and the inner gear 43, as well as meshing between the outer gear 45 and the rack 48, thereby achieving coordinated motion of multiple components controlled by a single drive, thereby improving energy utilization.

[0139] The clamping process of the optical prism with the corner pad 59:

[0140] When the Z-panels 51 move toward each other, they simultaneously drive the outer frame 52, the middle frame 53, the inner frame 54, and the end plate 55 to move toward the optical prism until the corner pad 59 contacts the optical prism. During this process, the corner pad 59 provides a reverse force to the movable column 57, and the movable column 57 transmits the aforementioned reverse force to the end plate 55, the middle frame 53, the inner frame 54, and the outer frame 52 in sequence through the ball head 56 (that is, the multi-stage connection between the ball head 56 and the different end plates 55 breaks the single alignment between the traditional multi-camera elastic clamp 581 and the clamped object, and can achieve stable clamping of different shapes of the same specifications and adaptability at multiple cameras, avoiding the problem of inconsistent clamping forces between multiple clamping units, helping to improve clamping accuracy, reduce the nonlinear synergy between external vibration factors and the productive vibration of the grinder or polisher itself, fully ensure the ideal and expected shear force between the two, and improve the processing finish of the prism);

[0141] During this process, through the friction between the movable column 57 and the angle frame 58, the elastic properties of the shock-absorbing spring 584 itself and the segmented movable connection between the end plate 55-inner frame 54 / middle frame 53-outer frame 52, the external vibration and production vibration caused by clamping differences are fully absorbed and decomposed, thereby improving the adaptability and stable clamping of the multi-position clamp 581 to different rough blanks.

[0142] The working principle of the optical prism processing device and processing method provided by the present invention is as follows: First, the top closing ring 35 is used to guide the rotation of the retaining ring 36. During this process, the position of the optical prism in the placement tube 27 is adjusted by the adjusting pin 39. Thereafter, the short-circuit plate 322 is driven to move by the telescopic cylinder 323, and then the mouth frame 321 drives the segmented plate 31 to reciprocate, finally realizing the alternating unloading of the optical prism in the placement tube 27 by the upper plate 33 and the lower plate 34;

[0143] Step 2: The rubber plate 313 and the clamp 581 guide and support the optical prism during discharge, and the rotation of the cam 319 causes the optical prism to fall only toward the leaf plate 315. The leaf plate 315 and the damping plate 317 reduce the kinetic energy of the optical prism when it slides down, ensuring the integrity of the placement of the optical prism.

[0144] Step 3: Finally, the outer gear 45 is driven to rotate by the inner gear 43. When the outer gear 45 rotates, the rack 48 synchronously drives the Z panel 51 under the dual support and guidance of the turntable 41 and the right-angle frame 47, and controls the outer frame 52, the middle frame 53, the inner frame 54 and the end plate 55 to move toward the optical prism until the movable column 57, under the guidance of the angle frame 58, controls the angle pad 59 to implement equal force clamping of the optical prism at different positions.
