Description

Technical Field

[0001] This invention relates to the field of mold blank burr removal technology, specifically to a device for removing burrs from the edges and corners of mold blanks using light stimulation. Background Technology

[0002] As the mold processing industry continues to demand higher requirements for workpiece surface quality and deburring efficiency, the automated processing steps in its production process are becoming increasingly complex, leading to a surge in the application of various laser processing equipment. Consequently, the daily tasks of workpiece clamping and positioning for operators are becoming increasingly demanding.

[0003] Typically, laser removal equipment is used for non-contact ablation treatment of burrs and flash on the surface of workpieces. However, in the process of removing burrs from the edges and corners of a mold blank, the workpiece often needs to be placed on a rotary table and rotated in increments to align the four corners of the workpiece with the laser beam treatment area in sequence, thereby performing omnidirectional deburring. During this process, the operator needs to adjust the relative position of the workpiece and the laser head according to the shape of the workpiece. For cuboid workpieces, the distances from the long side and the short side to the rotation center are different. Using equal-angle rotation without position compensation causes the corners to deviate from the laser focus, resulting in uneven deburring effect or even failure. After the work is completed, the operator has to repeat the above actions for the next workpiece. The repeated assembly and adjustment operations are time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device for removing burrs and irritants from the edges and corners of mold blanks. This device solves the problem of the inability to automatically adjust the relative position between the workpiece and the laser beam processing area during the rotary processing of cuboid mold blanks, which necessitates frequent manual intervention.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for removing burrs and irritants from the edges of a mold blank, comprising a frame; a laser processing assembly disposed on the frame; a rotating shaft slidably connected to the frame; a trigger connected to the periphery of the rotating shaft; and a guide plate disposed on the frame, the guide plate having a guide portion located on the rotation path of the trigger. When the rotating shaft rotates and moves the trigger to abut against the guide portion, the guide portion pushes the trigger and drives the rotating shaft to slide, thereby adjusting the relative position between the workpiece and the laser beam processing area of ​​the laser processing assembly.

[0006] Preferably, it also includes a support base, which is fixed on the rotating shaft.

[0007] Preferably, it also includes a drive unit, which includes a worm wheel, a worm, and a telescopic transmission rod. The worm wheel is fixedly connected to the rotating shaft, the worm meshes with the worm wheel, and one end of the telescopic transmission rod is connected to the worm.

[0008] Preferably, it also includes an elastic reset component, a guide rod is fixed on the frame, a sliding seat is sleeved on the rotating shaft, the sliding seat slides with the guide rod, and the elastic reset component is sleeved on the guide rod.

[0009] Preferably, the trigger is provided with a first guide slope, and the guide part is provided with a second guide slope that cooperates with the first guide slope.

[0010] Preferably, the laser processing component is slidably mounted on the frame, and the frame is equipped with a lead screw drive component, which is connected to the laser processing component in a transmission manner.

[0011] Preferably, it also includes a one-way damper, which includes a damping cylinder, a damping rod and a piston. The damping cylinder is fixed on the frame, one end of the damping rod is connected to the sliding seat, and the other end of the damping rod extends into the damping cylinder and is fixedly connected to the piston. A partition plate is fixed inside the damping cylinder. A one-way flow groove and a damping flow channel are provided on the partition plate. An elastic diaphragm that can be opened and closed is provided on the one-way flow groove.

[0012] Preferably, the frame is provided with a sliding groove to accommodate the sliding of the rotating shaft, and a flexible protective curtain is provided at the opening of the sliding groove.

[0013] Preferably, a rotatable rotating rod is provided below the flexible protective curtain, the rotating rod has a protrusion, a trigger rod is fixed on the damping rod, and an inclined guide block is provided on the trigger rod.

[0014] Preferably, it also includes a support frame and a clamping assembly disposed on the support frame, the clamping assembly being located above the support base.

[0015] This invention provides a device for removing burrs and irritants from the edges and corners of mold blanks using light. It has the following beneficial effects: 1. This invention solves the problem in the prior art of deburring the edges and corners of non-square workpieces such as cuboids by adopting a structure in which a rotating shaft, a trigger element, and a guide element work together. This is because it is difficult to automatically adjust the relative position of the workpiece and the laser beam of the laser processing component during the rotation process to deal with the edge and corner burr areas of the workpiece. As a result, it can adaptively switch the position of different edges and corners during the continuous rotation processing of the equipment, which greatly improves the degree of automation and processing efficiency.

[0016] 2. This invention, through a unidirectional flow channel, damping channel, and partition plate, enables the equipment to generate unidirectional damping force when the elastic reset component drives the rotating shaft to reset, effectively avoiding the problems of impact, vibration, and position overshoot caused by excessively fast reset speed, and greatly improving the stability of workpiece positioning during laser deburring process.

[0017] 3. The present invention uses a flexible protective curtain, a rotating rod and a protrusion to enable the equipment to automatically cover the moving slot and prevent debris from falling in. During each reset action, the curtain is actively tapped to shake off the attached dirt, which effectively avoids debris and dust contaminating the sliding mechanism and causing jamming or wear.

Detailed Implementation

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

[0021] Example 1, please refer to the appendix. Figure 1 - Appendix Figure 4This is the first embodiment of the present invention, which provides a device for removing burrs from the edges and corners of a mold blank, including a frame 100, a laser processing component 110, a rotating shaft 200, a trigger 300, and a guide plate 400. The frame 100 provides support and positioning for the other components. The laser processing component 110 is disposed on the frame 100 and is used to generate a laser beam to process the burr areas of the workpiece. The rotating shaft 200 is slidably connected to the frame 100 and is also rotatably disposed on the frame 100 about its own axis. One end of the rotating shaft 200 is configured to carry the workpiece to be processed. The trigger 300 is fixedly connected to the peripheral surface of the rotating shaft 200 and rotates or slides with the rotating shaft 200. The guide plate 400 is fixed to the frame 100 and is provided with a guide portion 410, which is located on the rotation path traversed by the trigger 300 when rotating around the rotating shaft 200.

[0022] When the rotating shaft 200 rotates around itself, the trigger 300 fixed to its periphery rotates synchronously. When the trigger 300 rotates to its rotation path and meets and abuts against the guide 410, the guide 410 applies a force to the trigger 300. Since the guide 410 is fixed to the frame 100 and cannot move, this force will cause the trigger 300 to drive the rotating shaft 200 to overcome the frictional resistance of its sliding connection and slide. The sliding changes the relative spatial position between the workpiece fixed on the rotating shaft 200 and the laser beam processing area emitted by the laser processing component 110, thereby realizing the automatic adjustment function of different corner areas of the workpiece entering the processing area in sequence, such as the deburring treatment of a cuboid workpiece.

[0023] Please see the appendix Figure 4 - Appendix Figure 5 In this embodiment, one end of the rotating shaft 200 is used to support the workpiece. This support method can be end face support or it can be achieved through an intermediate adapter. The slidable and rotatable connection between the rotating shaft 200 and the frame 100 can be achieved through a combination of sliding bearings, linear bearings, or bushings and guide keys. The number of trigger elements 300 can be one, two, or more. When multiple trigger elements 300 are provided, each trigger element 300 is preferably evenly distributed along the circumference of the rotating shaft 200 to achieve multi-angle triggering or multi-station adjustment. The guide portion 410 on the guide plate 400 can be a raised block structure, columnar structure, or wedge structure, and its side facing the trigger element 300 has a guide surface for contact and guidance.

[0024] Please see the appendix Figure 4 - Appendix Figure 5In this embodiment, the trigger 300 is installed on the periphery of the rotating shaft 200 through a detachable connection structure. The connection structure can be a threaded connection, screw clamping, or quick-release clamping sleeve, etc. Since the edge and corner processing of workpieces is usually carried out in batches of workpieces of the same specification and shape as processing units, rather than frequently changing the shape of a single workpiece, the operator only needs to adjust the installation state of the trigger 300 when switching batches.

[0025] Specifically, when the batch of workpieces to be processed is cuboid, the trigger 300 is installed on the rotating shaft 200, so that the trigger 300 and the guide part 410 periodically contact each other during the operation of the equipment, generating displacement to adapt to the changes in the position of the cuboid's corners. When the batch of workpieces to be processed is cube, the trigger 300 can be removed from the rotating shaft 200. At this time, the rotating shaft 200 only rotates at a preset angle and no longer slides. The equipment switches to the conventional rotary processing mode suitable for cube workpieces. Since the number of workpieces processed in the same batch is usually large, the operator only needs to perform the installation or removal operation of the trigger 300 once before the batch begins, without repeated adjustments during the processing of a single piece. This ensures the applicability of the equipment to workpieces of different shapes and avoids the risk of loosening of connections caused by frequent disassembly and assembly. The bottom of the rotating shaft 200 can be fixed by a slider, which can slide along a preset trajectory within the frame 100, improving sliding stability.

[0026] Example 2, please refer to the appendix. Figure 2 - Appendix Figure 5 This is the second embodiment of the present invention, which is based on embodiment 1 and further includes a support seat 210. The support seat 210 is fixed to one end of the rotating shaft 200, that is, the support seat 210 and the rotating shaft 200 are fixedly connected. This connection can be achieved by key connection, interference fit, welding or integral molding, etc. The side surface of the support seat 210 facing away from the rotating shaft 200 is a support surface for placing and supporting the workpiece. This support surface is preferably a contoured surface adapted to the bottom shape of the workpiece. The setting of the support seat 210 makes the clamping and disassembly of the workpiece more convenient, while avoiding the workpiece from contacting the end face of the rotating shaft 200, which would cause wear or inaccurate positioning.

[0027] Please see the appendix Figure 2 and attached Figure 7 This embodiment also includes a drive unit 500, which is connected to the rotating shaft 200 for driving the rotating shaft 200 to rotate. Specifically, the drive unit 500 includes a worm gear 510, a worm 520, and a telescopic transmission rod 530.

[0028] The worm gear 510 is fixedly connected to the outer circumferential surface of the rotating shaft 200. The two can be keyed or interference-fitted to ensure that the worm gear 510 rotates with the rotating shaft 200. At the same time, the worm gear 510 allows the rotating shaft 200 to slide. The worm 520 meshes with the worm gear 510. One end of the telescopic transmission rod 530 is fixedly connected to the axle or hub of the worm 520, and the other end is configured to connect to the output end of an external power source, such as an electric motor or hydraulic motor.

[0029] The telescopic transmission rod 530 has the ability to adaptively extend and retract along its own length. Its structure can be a sleeve-type telescopic rod, consisting of a coaxially fitted outer cylinder and an inner rod. The two are circumferentially fixed and can slide relative to each other via a guide key or spline. When the rotating shaft 200 slides under the action of the trigger 300 and the guide part 410, the worm gear 510 is fixed to the rotating shaft 200 and slides synchronously with it. The worm 520 is fixed to the slider at the bottom of the rotating shaft 200 via a bracket. At this time, the telescopic transmission rod 530, through its adaptive extension and retraction function, allows the inner rod to slide relative to the outer cylinder, thereby changing the distance between the worm 520 and the power source, ensuring continuous power transmission without interference or disengagement. Furthermore, the self-locking function of the worm gear 510 and worm 520 transmission ensures stability during workpiece processing.

[0030] Please see the appendix Figure 2 Appendix Figure 4 and attached Figure 5 This embodiment also includes an elastic reset member 600. Specifically, at least one guide rod 610 is fixed on the frame 100. The guide rod 610 extends in a direction parallel to the rotation shaft 200. A sliding seat 620 is sleeved on the rotation shaft 200. The sliding seat 620 slides with the guide rod 610 through its internal guide hole, that is, the guide rod 610 passes into the guide hole of the sliding seat 620. The two are in clearance fit or through linear bearing fit, so that the sliding seat 620 can freely translate along the length direction of the guide rod 610. The sliding seat 620 and the rotation shaft 200 can be connected by relative rotation, such as through bearing sleeve, so that the rotation shaft 200 can rotate freely relative to the sliding seat 620. The displacement of the sliding seat 620 will synchronously drive the rotation shaft 200 to produce the same displacement.

[0031] The elastic reset member 600 can be a tension spring or a combination of multiple springs. When it is a tension spring, its two ends abut or connect with the end face of the sliding seat 620 and the corresponding stop wall of the frame 100, respectively. When the rotating shaft 200 slides in a certain direction under the action of external force, the sliding seat 620 stretches the elastic reset member 600. When the external force is released, the elastic reset member 600 pulls the sliding seat 620 and the rotating shaft 200 back to the initial position.

[0032] Please see the appendix Figure 4 - Appendix Figure 5 In this embodiment, the trigger 300 is provided with a first guide slope, which is located on the side of the trigger 300 facing the guide portion 410. The guide portion 410 is provided with a second guide slope, which is located on the side of the guide portion 410 facing the trigger 300. The inclination direction of the second guide slope matches the inclination direction of the first guide slope. When the rotating shaft 200 rotates and drives the trigger 300 to contact the guide portion 410, the first guide slope and the second guide slope first come into contact and slide relative to each other. The slope between the two slopes transforms the force of the rotating part of the rotating shaft 200 into a sliding pushing force, making the pushing process smoother.

[0033] Furthermore, to reduce contact friction, the trigger 300 is also provided with a rolling element, which can be a ball or a roller. The rolling element is rotatably embedded on the end face or inclined surface of the trigger 300 facing the guide portion 410. When the trigger 300 contacts the guide portion 410, the rolling element and the surface of the guide portion 410 form rolling contact, which transforms the original sliding friction into rolling friction, significantly reducing frictional resistance and wear, and extending service life.

[0034] To accommodate workpieces of different sizes or different adjustment strokes, the guide plate 400 is provided with multiple positioning holes. These positioning holes are distributed at different angles along the circumference of the guide plate 400 or at different distances along the radial direction. The guide part 410 can be selectively fixed to any one of the positioning holes by fasteners such as bolts, screws or pins. By changing the installation position of the guide part 410 on the guide plate 400, the relative eccentricity between the guide part 410 and the axis of the rotating shaft 200 or its circumferential trigger angle can be adjusted, thereby changing the pushing distance generated when the trigger 300 contacts the guide part 410, realizing the adjustable function of the workpiece position and improving the adaptability of the equipment to workpieces of different specifications.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 In this embodiment, the laser processing component 110 is slidably mounted on the frame 100. Specifically, the frame 100 is provided with a lead screw drive assembly, which includes a lead screw, a nut, and a motor that drives the lead screw to rotate. The nut is fixedly connected to the base of the laser processing component 110. The lead screw and the nut cooperate to form a helical transmission. When the lead screw is driven to rotate by the motor, the nut drives the laser processing component 110 to translate along the axis of the lead screw, thereby driving the laser processing component 110 to move along the area of ​​the workpiece to be deburred, realizing point-by-point or continuous scanning processing of the burr area on the workpiece.

[0036] Example 3, please refer to the appendix. Figure 4 - Appendix Figure 6This is the third embodiment of the present invention. Based on embodiment 1 or embodiment 2, this embodiment further includes a unidirectional damper 700. The unidirectional damper 700 is disposed between the frame 100 and the rotating shaft 200. It is used to provide unidirectional damping force when the rotating shaft 200 is reset under the action of the elastic reset member 600. That is, damping is generated only in the reset direction, while the damping is very small or non-damped in the reverse movement, thereby absorbing the impact vibration that the elastic reset member 600 may generate during the reset process.

[0037] Specifically, the unidirectional damper 700 includes a damping cylinder 710, a damping rod 720, and a piston 730. The damping cylinder 710 is a hollow cylindrical body with one end open, which contains a damping medium, such as silicone oil or hydraulic oil. The damping cylinder 710 can be fixed on the frame 100. The other end of the damping rod 720 extends into the interior of the damping cylinder 710 and is fixedly connected to the piston 730. The piston 730 and the damping cylinder 710 maintain a sealed sliding fit.

[0038] A partition disk 740 is fixed inside the damping cylinder 710, which divides the inner cavity of the damping cylinder 710 into a first chamber and a second chamber. The partition disk 740 has a one-way flow groove 741 and at least one damping flow channel 742. The one-way flow groove 741 is an opening that penetrates the partition disk 740. An openable elastic diaphragm is provided on the opening. One edge of the elastic diaphragm is fixed to the partition disk 740, and the rest can be elastically deflected. When the medium flows from the first chamber to the second chamber and through the one-way flow groove 741, the medium pressure pushes the elastic diaphragm open, forming a larger flow cross section. At this time, the damping is very small. When the medium flows in the opposite direction, the medium pressure presses the elastic diaphragm against the surface of the partition disk 740, closing the one-way flow groove 741. The medium is forced to pass through the damping flow channel 742. Since the area of ​​the damping flow channel 742 is very small, a large flow resistance is generated when the medium passes through, thereby achieving a one-way damping effect.

[0039] Please see the appendix Figure 4 - Appendix Figure 6 During operation, when the rotating shaft 200 is pushed by the trigger 300 to slide away from the laser processing component 110, the damping rod 720 linked to the rotating shaft 200 drives the piston 730 to move within the damping cylinder 710. At this time, the medium pushes the elastic diaphragm open through the one-way flow channel 741. The damping force is very small and does not affect the normal sliding stroke. When the elastic reset component 600 drives the rotating shaft 200 to reset, the damping rod 720 drives the piston 730 to move in the opposite direction. At this time, the elastic diaphragm closes, and the medium can only flow slowly through the damping flow channel 742, generating a large damping force, slowing down the reset speed of the rotating shaft 200, absorbing vibration energy, avoiding impact and vibration caused by excessive reset speed, and improving the stability of equipment operation.

[0040] Example 4, please refer to the appendix. Figure 7 - Appendix Figure 8 This is the fourth embodiment of the present invention. Based on embodiment 3, this embodiment further includes a moving groove 130 on the frame 100 to accommodate the sliding of the rotating shaft 200. The moving groove 130 is an elongated groove extending along the sliding direction of the rotating shaft 200. To prevent burrs, debris, or dust generated during processing from falling into the moving groove 130 and causing obstruction of the sliding of the rotating shaft 200 or increased wear, a flexible protective curtain 800 is provided at the opening of the moving groove 130. The flexible protective curtain 800 can be made of rubber, silicone, canvas, or woven metal sheet. The flexible protective curtain 800 is arranged at an inclination so that dirt falling on its surface can roll off along the inclination direction under its own gravity.

[0041] One end of the flexible protective curtain 800 is rotatably connected to the support seat 210, and the other end of the flexible protective curtain 800 is wound around a rotatable take-up shaft. The take-up shaft is rotatably mounted inside the frame 100 through a bearing. A return spring is provided between the take-up shaft and the frame 100. One end of the return spring is fixed to the take-up shaft and the other end is fixed to the frame 100. It can apply torque to the take-up shaft and has the function of rewinding the flexible protective curtain 800.

[0042] When the rotating shaft 200 drives the bearing seat 210 to slide away from the take-up shaft, the flexible protective curtain 800 is pulled out from the take-up shaft and covers the moving groove 130; when the rotating shaft 200 slides in the opposite direction under the action of the elastic reset member 600, the reset coil spring drives the take-up shaft to rotate, rewinding the extended flexible protective curtain 800 back, always keeping the flexible protective curtain 800 in a taut covering state, and preventing the moving groove 130 from being exposed.

[0043] The lower area of ​​the frame 100 adjacent to the flexible protective curtain 800, i.e. the lower end when it is tilted, is also provided with a negative pressure suction port. This negative pressure suction port is connected to an external negative pressure source, such as a vacuum cleaner or a vacuum pump, through a pipeline. During the operation of the equipment, the negative pressure suction port continuously generates negative pressure, sucking in and collecting the dirt particles that fall on the surface of the flexible protective curtain 800 and roll down its tilted surface, thereby achieving automatic cleaning.

[0044] To further prevent dirt from accumulating or adhering on the surface of the flexible protective curtain 800, this embodiment also includes a rotatable rotating rod 820 located below the flexible protective curtain 800. The rotating rod 820 extends along the length direction perpendicular to the flexible protective curtain 800, and its two ends are rotatably mounted on the frame 100 via bearings. One or more protrusions 821 are provided on the peripheral surface of the rotating rod 820. The protrusions 821 are outwardly extending block-shaped or columnar structures.

[0045] Please see the appendix Figure 8A trigger rod 750 is fixed on the damping rod 720. An inclined guide block is provided at the distal end of the trigger rod 750. The inclined guide block is located near the rotation path of the protrusion 821 on the rotating rod 820. When the damping rod 720 moves with the rotating shaft 200 toward the direction closer to the laser processing component 110, that is, the reset direction, the trigger rod 750 moves synchronously. The inclined guide block on it contacts and presses against the protrusion 821 on the rotating rod 820, pushing the protrusion 821 to drive the rotating rod 820 to rotate around its own axis at a certain angle. Its end strikes the flexible protective curtain 800 from below, causing the vibration generated by the flexible protective curtain 800 to further shake off the dirt attached to its surface, causing the dirt to roll off to the lower area.

[0046] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 7 This embodiment also includes a support frame 900 and a clamping assembly 910 disposed on the support frame 900. The support frame 900 is fixed to the frame 100 and extends upward. The clamping assembly 910 is located directly above the bearing seat 210, and its position is opposite to the bearing surface of the bearing seat 210. The support frame 900 is provided with a guide rail, and the clamping assembly 910 is slidably disposed on the guide rail. That is, the clamping assembly 910 slides with the guide rail through a slider or guide sleeve on it and can move along the length direction of the guide rail.

[0047] The clamping assembly 910 includes a clamping driver and a pressing member driven by the clamping driver. The clamping driver can be a cylinder, a hydraulic cylinder, or a cam drive mechanism. The pressing member is fixed to the driving end of the clamping driver, and its side surface facing the carrier 210 is the pressing surface. When the workpiece is placed on the carrier 210, the clamping driver drives the pressing member to move downward along the guide rail until the pressing surface presses it against the carrier 210 from the top of the workpiece, thereby clamping and fixing the workpiece and preventing the workpiece from loosening or shifting during the rotation or sliding of the rotating shaft 200.

[0048] Based on the foregoing embodiments, the general working principle of the device of the present invention is given below: Before starting the equipment, the operator selects the installation state of the trigger 300 according to the shape of the workpiece in this batch, either cube or cuboid: if it is a cuboid, the trigger 300 is installed on the periphery of the rotating shaft 200; if it is a cube, the trigger 300 is removed, the workpiece is placed on the bearing seat 210, and the clamping assembly 910 presses and fixes it.

[0049] During processing, the drive unit 500 drives the rotating shaft 200 to rotate through the meshing of the worm gear 510 and the worm 520. When the trigger 300 is installed and the workpiece is a cuboid, the trigger 300 contacts the guide part 410 fixed on the guide plate 400 every time the rotating shaft 200 rotates a certain angle. The guide inclined surfaces between the two cooperate to convert the rotational motion into a thrust along the rotating shaft 200, causing the rotating shaft 200 to slide against the elastic force of the elastic reset member 600, thereby changing the relative position of the workpiece and the laser processing component 110, so that the different edges and corners of the cuboid workpiece are aligned with the laser beam processing area in sequence. When the trigger 300 rotates past the guide part 410, the thrust disappears, and the elastic reset member 600 pushes the rotating shaft 200 to reset, preparing for the next switch. The one-way damper 700 provides damping during the reset process, absorbs impact energy, and avoids vibration. If the workpiece is a cube, the rotating shaft 200 only rotates at a preset angle, and the edges and corners of the workpiece enter the processing area in sequence without moving.

[0050] Driven by the lead screw drive assembly, the laser processing component 110 moves along the edge of the workpiece to remove burrs. The debris generated during processing falls onto the surface of the inclined flexible protective curtain 800 and rolls down to the negative pressure suction port at the lower end under the action of gravity, where it is sucked away. At the same time, when the rotating shaft 200 is reset, the trigger rod 750 on the damping rod 720 pushes the rotating rod 820 to rotate, knocking the lower surface of the flexible protective curtain 800 to shake off the attached dirt and ensure the cleaning effect.

[0051] For multiple workpieces in the same batch, the equipment repeats the above cycle without disassembling and assembling the trigger 300 during processing; it only needs to be adjusted once when switching batches.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
