Description

Technical Field

[0001] This utility model relates to the field of isostatic graphite cutting and testing technology, and in particular to an isostatic graphite cutting and testing device. Background Technology

[0002] Isostatic graphite, as a high-performance carbon material, is widely used in high-precision fields such as semiconductors, photovoltaics, nuclear energy, and molds. Its quality directly affects the performance, safety, and reliability of downstream products, therefore, rigorous quality testing is essential.

[0003] Currently, the stability of the process is mainly verified and defective products are eliminated through non-destructive testing (such as ultrasonic and X-ray) and physicochemical analysis (such as density and compressive strength). According to quality inspection requirements, isostatic graphite needs to be cut before flaw detection to ensure the required test plane.

[0004] Because the number of isostatic graphite wire cuts is large, the operating space for lathe operators and flaw detectors is small. Each isostatic graphite part weighs between 3.4 kg and 35 kg, and the back-and-forth handling of isostatic graphite blocks results in high labor intensity for the operators, which is time-consuming and laborious.

[0005] Based on this, this utility model designs an isostatic graphite cutting and testing device that is easy to quickly turn around in the workshop, in order to better solve the problems encountered in the prior art. Utility Model Content

[0006] To solve one of the aforementioned technical problems, the present invention employs the following technical solution: an isostatic graphite cutting and testing device, comprising a conveying mechanism, a ground-connecting frame installed at the four corners of the bottom of the conveying mechanism, an angle steel support platform installed above the conveying mechanism, one bottom side of the angle steel support platform being fixedly installed on the upper side of the ground-connecting frame via a support corner seat, guide grooves spaced apart along the length direction on the top of the angle steel support platform, a sliding cutting unit cooperating with two of the guide grooves being installed below the angle steel support platform, the top of the sliding cutting unit extending to the top of each guide groove and being fixedly connected to the bottom of a sliding seat, a sliding control component installed between the sliding seat and the rear vertical section of the angle steel support platform, the sliding control component being used to drive the sliding seat to reciprocate along the width direction of the conveying mechanism, and a detector fixedly installed on the front side wall of the angle steel support platform.

[0007] Based on any of the above technical solutions, a further optimization is made as follows: the sliding cutting unit includes a synchronous electric cylinder that is vertically arranged and inserted into the corresponding guide groove. The top of each synchronous electric cylinder is fixedly connected to the bottom of the sliding seat. The bottoms of the two synchronous electric cylinders are fixed to the top of a horizontally arranged lifting seat. A vertically arranged servo motor is fixedly installed at the bottom of the lifting seat. A swing seat is fixedly installed at the bottom of the motor shaft of the servo motor. A micro laser cutter is installed on the side of the swing seat facing the blocky isostatic graphite at its corresponding position. The micro laser cutter is used to follow the servo motor to swing back and forth at a set angle and complete the cutting of the isostatic graphite surface. The cutting stroke of the micro laser cutter is adjustable as needed.

[0008] Based on any of the above technical solutions, a further optimization is made as follows: the sliding control component includes a telescopic electric cylinder horizontally arranged above the angle steel support platform, the rear end of the cylinder of the telescopic electric cylinder is fixed to the vertical section of the angle steel support platform, and the telescopic end of the telescopic electric cylinder is fixed to the middle side wall of the sliding seat.

[0009] Based on any of the above technical solutions, a further optimization is made: the detector includes a mounting base fixedly installed in the middle of the front side wall of the angle steel support platform, and an ultrasonic flaw detection device is fixedly installed on the mounting base.

[0010] Based on any of the above technical solutions, a further optimization is made as follows: a negative pressure air duct is fixedly installed in the middle of the vertical section of the angle steel support platform that is positioned opposite to the micro laser cutter. The negative pressure air duct has isostatic graphite at the position to be cut at the negative pressure air outlet, which is used to collect some of the cut-off waste during operation. The negative pressure air duct is connected to an external negative pressure device through a negative pressure pipeline.

[0011] Based on any of the above technical solutions, a further optimization is made as follows: the conveying mechanism adopts a belt conveyor, and the top of the conveyor belt of the belt conveyor is used to place the block-shaped isostatic graphite to be cut and conveyed.

[0012] Based on any of the above technical solutions, a further optimization is that each of the synchronous electric cylinders and the guide groove at its corresponding position are fitted with a gap.

[0013] Based on any of the above technical solutions, a further optimization is made: each isostatic graphite to be tested is placed on top of the conveyor belt of the belt conveyor and maintains a preset interval distance.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model forms a stable support structure through the ground frame and angle steel support platform. Combined with the fixed connection of the support corner seat, it provides reliable mechanical support for the conveying mechanism, sliding cutting unit and testing equipment, ensuring the installation accuracy and operational stability of each component.

[0016] 2. This utility model utilizes the cooperation between the guide groove and the sliding cutting unit, combined with the telescopic electric cylinder to drive the sliding seat to move laterally, so as to realize the flexible adjustment of the cutting position of the micro laser cutter, which can adapt to the cutting needs of isostatic graphite of different width specifications, and improve the versatility and processing flexibility of the device.

[0017] 3. This utility model integrates a synchronous electric cylinder, a servo motor, and a miniature laser cutter. The cutting depth is adjusted by the vertical lifting of the synchronous electric cylinder, and the cutting position is changed by the servo motor driving the swing seat. This allows the laser cutting path to be adjusted as needed, enabling cutting operations of different thicknesses and shapes, thus expanding the applicability of the device.

[0027] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-6 As shown in the image.

[0028] Example 1: An isostatic graphite cutting and testing device includes a conveying mechanism. A ground-connecting frame 1 is installed at the four corners of the bottom of the conveying mechanism. An angle steel support platform 2 is installed above the conveying mechanism. One side of the bottom of the angle steel support platform 2 is fixedly installed on the upper side of the ground-connecting frame 1 via a support corner seat 3. Guide grooves 4 are spaced apart along the length of the top of the angle steel support platform 2. A sliding cutting unit that cooperates with two of the guide grooves 4 is installed below the angle steel support platform 2. The top of the sliding cutting unit extends to the top of each guide groove 4 and is fixedly connected to the bottom of a sliding seat 5. A sliding control component is installed between the sliding seat 5 and the rear vertical section of the angle steel support platform 2. The sliding control component is used to drive the sliding seat 5 to reciprocate along the width direction of the conveying mechanism. A detector is fixedly installed on the front side wall of the angle steel support platform 2.

[0029] The isostatic graphite cutting and testing device of this utility model relies on the ground frame 1 to provide bottom support for the conveying mechanism and connect to the ground. The angle steel support platform 2 is fixed to the ground frame 1 through the support corner seat 3 to form the upper frame structure.

[0030] Two guide chutes 4 are set along the length of the angle steel support platform 2 to provide lateral movement guidance for the sliding cutting unit. During operation, the sliding cutting unit is fixed to the sliding seat 5 at the top and moves back and forth along the width direction of the conveying mechanism (i.e., the extension direction of the guide chutes 4) under the drive of the sliding control component. The cutting position is adjusted laterally according to the current size of the blocky isostatic graphite. After the isostatic graphite is cut, it will pass through the detector installed on the front side wall of the angle steel support platform 2 to detect the cut isostatic graphite 16 under the conveying action of the conveying mechanism. In addition, it should be noted that the conveyor belt of the conveying mechanism remains stationary during the cutting operation to ensure the smooth progress of the cutting action.

[0031] Based on any of the above technical solutions, a further optimization is made as follows: the sliding cutting unit includes a synchronous electric cylinder 6 that is vertically arranged and inserted into the corresponding guide groove 4. The top of each synchronous electric cylinder 6 is fixedly connected to the bottom of the sliding seat 5. The bottoms of the two synchronous electric cylinders 6 are fixed to the top of a horizontally arranged lifting seat 7. A vertically arranged servo motor 8 is fixedly installed at the bottom of the lifting seat 7. A swing seat 9 is fixedly installed at the bottom of the motor shaft of the servo motor 8. A micro laser cutter 10 is installed on the side of the swing seat 9 facing the block-shaped isostatic graphite 16 at its corresponding position. The micro laser cutter 10 is used to follow the servo motor 8 to swing back and forth at a set angle and complete the cutting of the surface of the isostatic graphite 16. The cutting stroke of the micro laser cutter 10 is adjustable as needed.

[0032] The sliding control component allows for flexible adjustment of the cutting position, adapting to the cutting requirements of isostatic graphite 16 with different width specifications; the spatial layout of the detector and the cutting unit integrates the cutting and inspection processes, improving production efficiency.

[0033] Specifically, the conveying mechanism is used to carry and transport the block-shaped isostatic graphite 16 to be processed; the ground frame 1 and the angle steel support platform 2 constitute the support structure of the device, ensuring the installation accuracy and mechanical stability of each functional component; the guide chute 4 cooperates with the sliding cutting unit to realize the lateral positioning of the cutting unit; the sliding control component serves as a power source to drive the cutting unit to move laterally; the detector performs real-time detection of the cutting quality, forming a closed-loop processing flow.

[0034] The telescopic movement of the synchronous electric cylinder 6 drives the lifting seat 7 to move in the vertical direction (i.e., perpendicular to the plane of the conveying mechanism), thereby realizing the height adjustment of the micro laser cutter 10 to adapt to the cutting of different thicknesses of the surface layer of isobaric graphite of different heights.

[0035] A servo motor 8 is mounted at the bottom of the lifting base 7. Its motor shaft drives the swing base 9 to move the miniature laser cutter 10 back and forth at a set angle, so that the laser cutting path can be adjusted as needed, thereby completing the cutting of the surface of the blocky isostatic graphite 16. The cutting stroke can be adjusted by adjusting the extension and retraction of the synchronous electric cylinder 6 or the swing angle range of the servo motor 8.

[0036] The synchronous movement of the two synchronous electric cylinders 6 ensures that the lifting seat 7 rises and falls horizontally, avoiding tilting and ensuring the verticality of the cut; the cooperation between the servo motor 8 and the swing seat 9 enables the laser cutter to swing at an angle, which can complete straight cuts and improve processing flexibility; the adjustable cutting stroke design adapts to isostatic graphite 16 with different thicknesses or cutting depth requirements, expanding the applicability of this device.

[0037] Based on any of the above technical solutions, a further optimization is made as follows: the sliding control component includes a telescopic electric cylinder 11 horizontally arranged above the angle steel support platform 2, the rear end of the cylinder of the telescopic electric cylinder 11 is fixed to the vertical section of the angle steel support platform 2, and the telescopic end of the telescopic electric cylinder 11 is fixed to the middle side wall of the sliding seat 5.

[0038] When the telescopic electric cylinder 11 is energized, its telescopic end makes a linear reciprocating motion, which drives the sliding seat 5 to move along the width direction of the conveying mechanism (i.e., horizontally). Then, through the sliding cutting unit fixed to the bottom of the sliding seat 5, the micro laser cutter 10 moves horizontally synchronously with the sliding seat 5, thereby realizing the adjustment of the cutting position in the width direction of the isostatic graphite.

[0039] Using the telescopic electric cylinder 11 as the power source, it has the advantages of fast response speed, high displacement control accuracy, and stable output thrust. It can accurately control the lateral movement distance of the sliding seat 5 to meet the high-precision positioning requirements of isostatic graphite cutting position. The structure is compact, with the electric cylinder horizontally set above the support platform, which does not occupy the bottom conveying space and optimizes the space utilization of the device.

[0040] The sliding control component provides lateral movement driving force for the sliding seat 5, realizing the position adjustment of the cutting unit in the width direction of isostatic graphite, so that the same device can adapt to the cutting of isostatic graphite of different width specifications, or to the requirements of multi-position cutting operations on a single isostatic graphite.

[0041] Based on any of the above technical solutions, a further optimization is made: the detector includes a mounting base 12 fixedly installed in the middle of the front side wall of the angle steel support platform 2, and an ultrasonic flaw detection device 13 is fixedly installed on the mounting base 12.

[0042] When isostatically pressed graphite is conveyed to the area below the detector via the conveying mechanism, the existing ultrasonic flaw detection equipment 13 emits ultrasonic waves towards the isostatically pressed graphite. By receiving the echo signals reflected from the inside of the isostatically pressed graphite, it analyzes whether there are defects such as cracks, pores, and inclusions inside the isostatically pressed graphite, thus realizing the internal quality inspection of the cut or original isostatically pressed graphite. The existing ultrasonic flaw detection equipment 13 has the advantages of high detection sensitivity, strong penetration, and the ability to detect internal defects, and is suitable for the inspection of materials with high density requirements such as isostatically pressed graphite. The mounting base 12 is set in the middle of the front side wall of the support platform, so that the detector and the cutting unit are spatially distributed front and back, forming a production line operation mode of cutting, conveying, and inspection, improving production continuity. Example 2: Compared with Example 1, this example also includes the following technical features:

[0043] Based on any of the above technical solutions, a further optimization is made as follows: a negative pressure air duct 14 is fixedly installed in the middle of the vertical section of the angle steel support platform 2, which is positioned opposite to the micro laser cutter 10. The negative pressure air duct 14 has isostatic graphite at the position to be cut at the negative pressure air outlet, which is used to collect some of the cut-off waste during operation. The negative pressure air duct 14 is connected to an external negative pressure device through a negative pressure pipeline.

[0044] When the miniature laser cutter 10 performs cutting operations, an external negative pressure device creates a negative pressure environment inside the negative pressure duct 14 through negative pressure pipelines. Cutting debris is drawn into the negative pressure vent by the airflow and transported through pipelines to an external collection device, achieving real-time debris collection. The layout, positioned opposite the cutting unit, ensures a short and efficient debris collection path. Connecting to external equipment via negative pressure pipelines facilitates centralized debris processing, meeting industrial environmental protection requirements. This keeps the work area clean and reduces debris interference with subsequent inspection processes (e.g., preventing excessive debris from obscuring the inspection area). Furthermore, the negative pressure airflow washing over the cutting surface aids in heat dissipation, lowers local temperatures, and reduces the risk of material thermal deformation.

[0045] Based on any of the above technical solutions, a further optimization is made: the conveying mechanism adopts a belt conveyor 15, and the top of the conveyor belt of the belt conveyor 15 is used to place the block-shaped isostatic graphite to be cut and conveyed.

[0046] When the isobaric graphite moves with the belt to the underside of the sliding cutting unit, the sliding cutting unit and the sliding control component work together to adjust the horizontal cutting position. The synchronous electric cylinder 6 drives the cutter to feed vertically and perform the cutting operation. After the cutting is completed, the isobaric graphite continues to move with the conveyor belt to the underside of the detector for quality inspection.

[0047] Based on any of the above technical solutions, a further optimization is that each of the synchronous electric cylinders 6 and the guide groove 4 at its corresponding position are fitted with a gap.

[0048] The gap-fitting design reduces the assembly precision requirements between the guide slide 4 and the synchronous electric cylinder 6, simplifying processing and installation; it allows for a certain degree of lateral freedom, can absorb vibration or impact energy during equipment operation, reduce wear on rigid components, and extend service life.

[0049] Based on any of the above technical solutions, a further optimization is made: each isostatic graphite to be tested is placed on top of the conveyor belt of the belt conveyor 15 and maintains a preset interval distance.

[0050] The core function of the isobaric graphite spacing is to standardize the spatial distribution of isobaric graphite during the conveying process, providing conditions for precise control of the cutting and testing processes, and facilitating subsequent isobaric graphite sorting, packaging and other processes.

[0051] Working principle: The block-shaped isostatic graphite to be cut and inspected is placed on the conveyor belt of belt conveyor 15 at preset intervals. Belt conveyor 15, driven by a motor, rotates the belt in a cyclical manner, conveying the isostatic graphite at a stable speed along the conveying direction (perpendicular to the extension direction of guide chute 4), allowing the isostatic graphite to pass sequentially through the cutting area and the inspection area. During this process, the spaced arrangement of the isostatic graphite avoids mutual interference and provides a reference for the automated control of subsequent processes. Conveying equipment is installed upstream and downstream of belt conveyor 15.

[0052] When the isobaric graphite moves with the belt to directly below the cutting area, the sliding control component (horizontally positioned telescopic electric cylinder 11) is activated:

[0053] The telescopic end of the telescopic cylinder 11 drives the sliding seat 5 to move back and forth along the width direction of the conveying mechanism (i.e. the extension direction of the guide groove 4), which in turn drives the sliding cutting unit fixed to the bottom of the sliding seat 5 to move laterally, so that the micro laser cutter 10 is aligned with the position of the isobaric graphite to be cut.

[0054] The guide groove 4 provides lateral movement guidance for the sliding cutting unit, and its gap insertion fit with the synchronous electric cylinder 6 can absorb mechanical tolerances and ensure smooth movement.

[0055] After completing the horizontal positioning, the synchronous electric cylinder 6 of the sliding cutting unit is activated: the two synchronous electric cylinders 6 extend and retract synchronously, driving the lifting seat 7 to move in the vertical direction (perpendicular to the plane of the conveying mechanism), adjusting the height of the micro laser cutter 10, and determining the cutting depth.

[0056] The servo motor 8 at the bottom of the lifting platform 7 drives the swing platform 9 to swing back and forth at a set angle, causing the miniature laser cutter 10 to follow the swing and perform laser cutting on the isobaric graphite surface along a set path. The cutting stroke can be adjusted by adjusting the extension and retraction of the synchronous electric cylinder 6 or the swing angle range of the servo motor 8.

[0057] During the cutting process, the negative pressure air duct 14, which is set opposite to the micro laser cutter 10, works synchronously: the external negative pressure equipment creates a negative pressure environment inside the negative pressure air duct 14 through the negative pressure pipeline. The waste generated during cutting is sucked into the negative pressure air vent under the action of airflow and transported to the external collection device through the pipeline, so as to realize the real-time removal of waste.

[0058] Airflow can also help dissipate heat from the cut surface, reducing the risk of material thermal deformation.

[0059] The cut isobaric graphite continues to move along the conveyor belt to the bottom of the detector: the ultrasonic flaw detection equipment 13 is fixed to the middle of the front side wall of the angle steel support platform 2 by the mounting base 12, emits ultrasonic waves to the isobaric graphite and receives the echo signal, analyzes whether there are defects such as cracks and pores inside the isobaric graphite, and completes non-destructive testing.

[0060] The test results can be fed back to the existing external control system to determine whether the isobaric graphite is qualified or to adjust the cutting process parameters.
