Technical Field
[0001] The present invention relates to the technical field of lens cutting, and in particular to a lens cutting machine and a cutting method thereof for optical communication products. Background Art
[0002] With the rapid development of the communications industry, the application scope of optical communication products is becoming wider and wider. Most optical communication products are processed using injection molding technology.
[0003] As customers have increasingly higher requirements for product appearance, the cutting size of the injection molded product gate is required to be less than 0.15mm, which has become a major difficulty in limiting the improvement of the injection molded product yield. Injection molded products usually have four or eight cavities in one mold. Manual cutting can only cut one product at a time, which is relatively inefficient. Improving product quality and cutting efficiency has become a major difficulty in the mass production of optical communication products.
[0004] Based on the above problems, there is an urgent need for a lens cutting machine and a cutting method for optical communication products, which are intended to reduce the size of the product gate and improve the cutting efficiency of the product. Summary of the Invention
[0005] The main purpose of the present invention is to provide a lens cutting machine and a cutting method for optical communication products, aiming to solve the problem of low cutting efficiency of optical communication product cutting machines in the prior art.

[0010] Optionally, a limiting groove matching the product to be cut is further arranged on the placement base.
[0011] Optionally, the first cutting tool assembly and the second cutting tool assembly have the same structure.
[0012] Optionally, the first cutting tool assembly includes an adjusting member and a plurality of cutting tools. The cutting edges of the cutting tools are inclined, and the adjusting member is used to adjust the height of the plurality of cutting tools relative to the product to be cut.

[0014] Optionally, the distance between a plurality of the product limiting columns is A1, the runner diameter of the product to be cut is A2, and A1≥A2 is satisfied.
[0015] To achieve the above object, the present invention further provides a cutting method, which includes the following steps: placing the product to be cut on the placement component; moving the placement component to a set cutting position; controlling the stroke of the cylinder unit through the control unit to make the first cutting tool assembly move downward to complete the first cutting of the product to be cut; moving the placement component out of the cutting position and taking out the product to be cut after the first cutting; rotating the product to be cut after the first cutting by 180° and then placing it on the placement component again; moving the placement component to the set cutting position; controlling the stroke of the cylinder unit through the control unit again to make the first cutting tool assembly move downward to complete the second cutting of the product to be cut, and taking out the product to be cut to obtain the product to be cut.

[0024] Embodiment 1: Please refer to the attached Figure 1 to the attached Figure 10In this embodiment, a lens cutting machine for optical communication products is provided, including a base assembly 1, a drive assembly 2 and a placement assembly 5. The placement assembly 5 and the drive assembly 2 are both arranged on the base assembly 1. The placement assembly 5 is used to place the product 6 to be cut. The drive assembly 2 is connected to a first tool assembly 3 and the first tool assembly 3 is placed above the product 6 to be cut. A second tool assembly 4 is arranged below the product 6 to be cut. The drive assembly 2 is used to drive the first tool assembly 3 to move downward to match the second tool assembly 4 to jointly complete the batch cutting operation of the products 6 to be cut.
[0025] It's important to note that existing technologies in the injection molding of optical communication products face significant technical bottlenecks, severely restricting improvements in production efficiency and product quality. Specifically, injection molded products typically utilize a four- or eight-cavity die design, and manual operation can only cut a single product at a time, resulting in a time-consuming and lengthy cutting process that struggles to meet the industry's urgent need for mass production.
[0026] Based on the above structure, the lens cutting machine provided in this embodiment first ensures the stability and vibration resistance of the overall equipment through the buffering effect of the base component 1, and secondly, the placement component 5 is used to place the product to be cut 6. Different from the prior art, the placement component 5 is tightly fitted with the product to be cut 6. After the placement component 5 covers the product to be cut 6, it effectively reduces the cutting offset that may exist during cutting. Finally, the driving component 2 drives the first tool component 3 to move downward to match the second tool component 4 to complete the batch cutting operation of the product to be cut 6. When performing batch cutting operations, the first tool component 3 and the second tool component 4 form a two-way cutting stance, which can not only significantly reduce the pressure required for a single cutting to complete the batch cutting operation, but also effectively avoid burrs or cracks caused by material stress concentration through symmetrical force application, thereby stably controlling the gate size within the process requirements.
[0027] It should also be noted that the Figure 11 As shown, the product to be cut 6 in this embodiment is a casting with eight cavities in one mold, and is a plastic product.
[0028] Taking product 6, which has eight cavities per mold, as an example, operators must cut the gate of each cavity one by one. This repetitive operation is labor-intensive and prone to yield fluctuations due to fatigue or operator errors. Furthermore, cutting accuracy is difficult to maintain. Furthermore, due to the extremely stringent customer requirements for the cutting size of injection molded product gates (less than 0.15mm), manual cutting relies on the operator's experience and feel. There is a lack of standardization in tool angle, pressure, and stroke control, making it prone to dimensional deviations and burrs, which directly affect the product's appearance and optical performance.
[0029] In addition, the adjustment of the tool height needs to be done manually, which is time-consuming and difficult to ensure the synchronization consistency of multiple tools. Moreover, the control of the cutting stroke lacks precise mechanical limit or sensor feedback, resulting in differences in the cutting effects of products in different batches. Finally, the prior art cannot achieve a breakthrough in the collaborative operation of multiple tools. Only a single acupuncture point can be processed in a single cut, leading to low overall efficiency. There is also a problem that the products manufactured by the cutting machine have relatively large gate sizes.
[0030] Based on the above problems, in this embodiment, a lens cutting machine for optical communication products is proposed. Through the fixed connection of the support plate 121 and the buffering effect of the cushion block 13, the stability and vibration resistance of the overall equipment are ensured, and the cutting deviation problem caused by insufficient rigidity of the traditional equipment is solved. Specifically, the driving assembly 2 integrates a cylinder unit 21, a control unit, and a fixing unit 22. Through the precise control of the cylinder stroke by the control unit, the vertical movement trajectory of the first tool assembly 3 is standardized. With the two-way biting effect of the second tool assembly 4, a two-way cutting force field is formed, which not only significantly reduces the pressure required for a single cut but also effectively avoids burrs or cracks caused by material stress concentration through symmetric force application, thereby stably controlling the gate size within 0.15 mm.
[0031] In addition, the collaborative design of the sliding system composed of the slide rail 52 and the chute 53 in the placement assembly 5 and the limit posts and the limit slots 55 enables the product to be cut 6 to be quickly positioned and move along a preset path. Combining the constraint conditions between the limit posts, the positional fixity of the multi-acupuncture point product during the cutting process is ensured, and the repeated positioning error caused by product displacement in traditional manual operations is solved.
[0032] Finally, through the secondary cutting process, using the geometric characteristics of the tool tilt angle, the gate residue is eliminated in stages. In the first cut, a pre-cut is formed by the cutting of the inclined blade. After rotation, the second cut completely separates the gate from the opposite direction, which not only avoids the tearing defect that may be caused by a single cut but also meets the ultra-fine size requirements through the superposition of two precise strokes.
[0033] The unified control of the height of the cutting tool 32 by the adjusting member 31 ensures the synchronization consistency of multiple tools, and solves the problems of time-consuming and difficult to reproduce in traditional manual adjustment. Finally, the technical solution in this embodiment improves the single operation from manually cutting a single acupuncture point to automatically processing multiple acupuncture points, significantly improving the cutting efficiency and the yield rate, while reducing the dependence on skilled workers, providing a reliable technical support for the large-scale production of optical communication products.
[0034] In some embodiments, the material of the cutting tool 32 is a cemented carbide blade.
[0035] In this embodiment, the base assembly 1 includes a base plate 11, a support structure 12, a cushion block 13, and positioning columns 14. The support structure 12 includes a plurality of fixedly connected support plates 121 which are jointly placed on the cushion block 13. The cushion block 13 is arranged on the base plate 11. The driving assembly 2 is arranged in the support structure 12 through the positioning columns 14.
[0036] Based on the above structure, the base assembly 1 adopts a multi-layer rigid framework and a precise positioning system. The base plate 11 serves as a basic bearing platform, on which a support structure 12 composed of multiple interlocked support plates 121 is installed through the cushion block 13 to form a stable three-dimensional framework system. The support structure 12 forms an interference fit with the driving assembly 2 through the positioning columns 14, effectively suppressing the vibration transmission during the cutting process.
[0037] In some embodiments, the number of support plates 121 is 4, and they are fixedly connected by welding or other means to ensure the support strength. In the appendix Figure 4 In the support plate 121 horizontally arranged on the upper part, there are fixing screw holes and positioning holes for fixing the cylinder unit 21. The design reference of the positioning holes is 6mm ± 0.1mm. Similarly, the design reference of the positioning columns 14 is 6mm ± 0.1mm to facilitate the precise assembly of the cylinder unit 21. On the support plate 121, cushion block 13, and base plate 11 horizontally arranged below, there are also positioning holes, and they are also limited by the positioning columns 14. In addition, the cushion block 13 is provided with double-sided screw holes, and the base plate 11 and the support plate 121 are fixed by screws. It can be understood that the base plate 11 is provided with adjusting screws to limit the moving distance of the placing assembly 5.
[0038] In this embodiment, the driving assembly 2 includes a cylinder unit 21, a control unit, and a fixing unit 22. The output end of the cylinder unit 21 is fixedly connected to the first tool assembly 3. The control unit is used to control the stroke of the cylinder unit 21. The cylinder unit 21 is fixedly arranged in the support structure 12 through the fixing unit 22.
[0039] It should be noted that the driving assembly 2 adopts a three-unit integrated architecture. The cylinder unit 21 selects a high-precision servo cylinder, and its piston rod is hardened and is flange-connected to the first tool assembly 3 in a hard connection. In particular, the perpendicularity between the installation axis of the cylinder unit 21 and the reference plane of the positioning column 14 is controlled within 0.003° by laser calibration to ensure the absolute orthogonality between the tool movement trajectory and the product cutting surface. This driving system can complete the full-stroke acceleration and deceleration within 20ms, and the response speed is increased by 60% compared with the ordinary pneumatic system. At the same time, through the pressure-displacement composite control mode, the fluctuation range of the cutting force is greatly reduced, fundamentally eliminating the problem of cutting burrs caused by pressure fluctuation.
[0040] In some embodiments, the control unit is a foot valve, and the telescoping of the stroke limiting component is adjusted through a foot switch to achieve the stroke of the cylinder unit 21.
[0041] In some other embodiments, the control unit integrates a PID closed-loop control algorithm and a laser displacement sensor to monitor the tool position in real time and dynamically adjust the air pressure supply.
[0042] In some embodiments, the fixing unit 22 adopts a combined structure of prestressed bolt groups and wedge locking blocks to form a multi-directional constraint system inside the support structure 12. In some embodiments, the maximum movement stroke of the cylinder unit 21 is 0 mm to 50 mm.
[0043] In this embodiment, the placement assembly 5 includes a placement seat 51, a slide rail 52, and a chute 53. The placement seat 51 is slidably disposed on the bottom plate 11 through the slide rail 52 and the chute 53, and a plurality of product limiting columns 54 are provided on the placement seat 51.
[0044] It can be understood that the placement assembly 5 adopts a composite positioning system of slide rail 52 - chute 53 - limiting column. Among them, the slide rail 52 is preferably made of hardened steel and is matched with a linear ball bearing. After laser calibration, the moving straightness error is ensured. The V-shaped chute 53 provided at the bottom of the placement seat 51 and the trapezoidal slide rail 52 on the bottom plate 11 form a self-aligning structure, which automatically compensates for the assembly gap within 0.05 mm during rapid pushing and pulling.
[0045] It can also be understood that the synergistic effect of the limiting column and the limiting groove 55 forms a three-dimensional constraint field, which suppresses the product amplitude within 2 μm during the cutting process. Combined with the phase cutting of the two-way tool, the roughness Ra value of the gate section is reduced from 0.25 μm to 0.08 μm, fully meeting the mirror-level requirements of optical devices; after actual measurement, the cutting machine in this embodiment optimizes the cutting size dispersion of multi-cavity products from ±0.05 mm in the traditional process to ±0.01 mm, and the product qualification rate is increased to 99.6%.
[0046] In some embodiments, the placement assembly 5 further includes a limiting screw to prevent the product 6 to be cut from falling off.
[0047] In this embodiment, a limiting groove 55 matching the product 6 to be cut is further provided on the placement seat 51.
[0048] In some embodiments, the limiting groove 55 is designed as an inverted trapezoid, with the bottom width being B1, the top width being B3, and the runner diameter of the product 6 to be cut being B2. The overall size of the limiting groove 55 is constrained as: B3 ≥ B2 ≥ B1. Preferably, the constraint relationship is: B2 - B1 = 0.06 mm, B3 - B1 = 0.16 mm.
[0049] In this embodiment, the structures of the first tool assembly 3 and the second tool assembly 4 are the same.
[0050] It can be understood that the first and second tool assemblies 4 adopt exactly the same modular structure, both including an adjusting member 31 and an inclined-edge cutting tool 32. A bidirectional shear force field is formed through an up-and-down symmetric layout. This symmetric structure generates mutually balanced acting forces during cutting, converting single-point stress into distributed stress, effectively avoiding the microcrack problem caused by traditional single-knife cutting. The phase difference cutting mechanism of the upper and lower tools forms a dynamic shear effect, greatly reducing the size of the gate cross-section.
[0051] In this embodiment, the first tool assembly 3 includes an adjusting member 31 and a plurality of cutting tools 32. The cutting edges of the cutting tools 32 are inclined. The adjusting member 31 is used to adjust the height of the plurality of cutting tools 32 relative to the product 6 to be cut.
[0052] It can be understood that the inclined cutting tool 32 forms a composite action mechanism of shearing and peeling through the decomposition of the cutting force vector: the inclined cutting edge reduces the cutting contact area and simultaneously converts the vertical component force into a horizontal shear force, effectively reducing the cutting resistance.
[0053] In this embodiment, the inclination range of the cutting edge of the cutting tool 32 is 20° to 30°.
[0054] In some embodiments, the selection of the cutting edge angle is related to the material and thickness of the product 6 to be cut. If the cutting edge angle is too small, it will lead to fast wear and high replacement frequency. If the cutting edge angle is too large, it will also lead to fast wear and high replacement frequency. This product is a plastic product, and the preferred inclination angle of the cutting edge of the cutting tool 32 is 25°.
[0055] In this embodiment, the distance between several product limit posts 54 is A1, and the runner diameter of the product 6 to be cut is A2, and A1≥A2 is satisfied.
[0056] It can be understood that through geometric constraint design, key technical problems such as product clamping deformation, positioning accuracy attenuation, and stress concentration of multi-cavity products existing in traditional cutting processes are solved. Specifically, the constraint relationship between the distance A1 between the product limit posts 54 and the runner diameter A2 of the product 6 to be cut constructs a dynamically balanced clamping system based on the collaborative optimization of material mechanics and contact mechanics.
[0057] When A1 = A2 + 0.1 mm (preferably with a tolerance of ±0.02 mm), finite element simulation shows that this design can improve the contact stress uniformity of the product by 75%, while controlling the clamping deformation within 0.008 mm, far lower than the deformation threshold of 0.03 mm for optical communication products. Specifically, the rhombic constraint field formed by the four limit posts generates symmetrically distributed supporting forces in the X-Y plane, and the resultant force direction forms an optimal angle of 55° - 65° with the axis of the product flow channel, effectively offsetting the lateral cutting force during the cutting process. Experimental data shows that this geometric constraint reduces the product displacement from 0.15 mm with traditional rigid fixtures to 0.02 mm. At the same time, through the reserved micro-gap of 0.05 - 0.15 mm, it not only avoids plastic deformation caused by over-positioning but also prevents the accumulation of micro-displacements caused by high-frequency vibrations. The above dynamic constraint mechanism complements the damping characteristics of the slide rail 52 system, absorbing impact energy through the elastic deformation of the limit posts at the moment of cutting, fundamentally solving the industry pain point of clamping and breaking of thin-walled lenses. In addition, the above constraint mechanism forms a mechanical coupling with the two-way tool, delaying stress release through the elastic buffering effect of the limit posts during the first cutting, and using the pre-stored elastic potential energy to accelerate material separation during the second cutting, eliminating the need for additional demolding processes.
[0058] Embodiment 2: A cutting method, the method comprising the following steps: Place the product 6 to be cut on the placement component 5; Move the placement component 5 to the set cutting position; Control the stroke of the cylinder unit 21 through the control unit to move the first tool assembly 3 downward to complete the first cutting of the product 6 to be cut; Move the placement component 5 out of the cutting position and take out the product 6 to be cut after the first cutting; Rotate the product 6 to be cut after the first cutting by 180° and then re-place it on the placement component 5; Move the placement component 5 to the set cutting position; Again, control the stroke of the cylinder unit 21 through the control unit to move the first tool assembly 3 downward to complete the second cutting of the product 6 to be cut, and take it out to obtain the product 6 to be cut.
[0059] It should be noted that based on the above method, through the innovative two-stage phase cutting process, the core process problems existing in traditional single cutting, such as excessive gate residue, material stress concentration, and unstable cutting surface quality, are solved. Specifically, this method uses the composite positioning mechanism of the slide rail 52 - slide groove 53 sliding system and the limit groove 55 - limit post to quickly fix the product 6 to be cut on the placement component 5, and realizes precise positioning through a programmatically controlled moving path, significantly reducing the man-hour waste caused by repeated adjustments in traditional manual operations.
[0060] In the cutting stage, the cylinder unit 21 in the driving assembly 2 and the control unit form a closed-loop control system, precisely regulating the downward pressure depth and speed of the first tool assembly 3 through preset stroke parameters to ensure the uniformity of the cutting force each time. Combining with the design of a two-way tool assembly with a blade inclination of 20° to 30°, when cutting for the first time, the inclined blade cuts in progressively to form a pre-cut, effectively dispersing the material stress and avoiding tearing or burrs caused by single-cutting; subsequently, the product to be cut 6 is rotated 180° and then cut for the second time, and the residual gate is completely separated by the reverse action of symmetric force application, so that the final cut size is stably controlled within 0.15 mm.
[0061] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
