Description

Technical Field

[0001] This invention relates to the field of microcrystalline glass plate processing equipment, specifically a cutting device for microcrystalline glass plate production. Background Technology

[0002] In the production of microcrystalline glass sheets, a circular wire saw can be used to perform wet horizontal wire cutting on sheets of a certain thickness. During processing, the feed platform supports the sheet material and gradually passes through the horizontal cutting section of the circular wire saw, while cutting fluid is supplied to the cutting area. After the sheet material passes through the horizontal cutting section with the feed platform, a thin product sheet is formed at the top, and a residual material sheet supported by the feed platform is formed at the bottom. A narrow kerf containing cutting fluid and cutting powder is formed between the two.

[0003] After the sheet is completely cut, cutting fluid and slurry remain between the relative cut surfaces of the product sheet and the remaining mother sheet, and a continuous liquid film or liquid bridge can easily form in the narrow cut. When lifting the product sheet, the slow introduction of outside air and the interface separation resistance will hinder the smooth detachment of the product sheet; if the interface is suddenly broken, the product sheet may also experience a sudden jump or local collision, increasing the risk of sheet breakage.

[0004] On the other hand, as the feed platform gradually moves the sheet material through the horizontal cutting section, the cut area of ​​the thin sheet gradually loses the direct support of the remaining mother plate. When the cutting is near the end, this area may sag locally under its own weight, cutting vibration, and the flow of cutting fluid, causing the remaining connecting area to be stressed and increasing the risk of edge chipping or breakage at the end.

[0005] If the fixed support is pre-placed on the cutting plane where the slit is to be formed, the support will be blocked by the uncut sheet material and may interfere with the horizontal cutting section and the drainage of liquid and chips; if the support is always located outside the cutting plane, it cannot provide direct support for the already cut area. Fixed support structures cannot simultaneously meet the requirements of avoidance during the cutting process, support for the already cut area, and auxiliary separation after cutting.

[0006] Therefore, without interfering with the horizontal cutting section and the drainage and chip removal, it is necessary to form a support for the cut area of ​​the product sheet as the cutting process progresses, and after the sheet is cut, the support should continue to be placed between the product sheet and the residual material mother plate, so as to provide conditions for the drainage and gas replenishment of the liquid interface and the bottom support before adsorption and material removal. Summary of the Invention

[0007] To overcome the shortcomings of the prior art, the present invention provides a cutting device for the production of microcrystalline glass plates, which solves the problems that during wet horizontal line cutting, the support component is difficult to balance avoidance, support of the cut area and drainage of liquid and chips, and it is difficult to maintain bottom support before adsorption and material removal while weakening the separation resistance of the continuous liquid interface after the plate is cut.

[0008] This invention employs the following technical solution: a cutting device for producing microcrystalline glass sheets, comprising a ring wire saw, a platform base, a feeding platform, and a stretching mechanism. The feeding platform has sliding clamping mechanisms on both sides, which hold multiple accompanying support belts that span the sheet and are spaced apart along the feeding direction. After the feeding platform moves to the set traction position of the accompanying support belts, the sliding clamping mechanisms sequentially cause the accompanying support belts to enter the liquid-containing kerf from below the cutting plane, abutting against the lower surface of the thin product sheet and moving with the feeding platform. The clamping distance of the sliding clamping mechanisms is adjusted by the stretching mechanism. Upon entering the kerf, the accompanying support belts are axially stretched, and their thickness dimension is less than the height of the liquid-containing kerf. After the sheet is cut, the stretching mechanism reduces the clamping distance, allowing the accompanying support belts to release some elongation while maintaining axial tension. After release, the thickness dimension of the uncompressed accompanying support belts is greater than the height of the liquid-containing kerf. After re-expansion, it abuts against the thin product sheet and the remaining material mother plate, forming a local pre-separation gap leading to the side edge of the sheet.

[0009] Furthermore, the thickness dimension of the accompanying support belt decreases as the axial elongation increases, and then increases again as the axial elongation decreases; the tensioning mechanism is in the tensioned position before the accompanying support belt enters the liquid-containing cut, so that the thickness dimension of the accompanying support belt is smaller than the height of the liquid-containing cut.

[0010] Furthermore, the stretching mechanism also has a release position, which is switched from the stretching position to the release position after the plate is cut; the clamping distance on both sides under the stretching position is a first distance, and the clamping distance on both sides under the release position is a second distance. The second distance is less than the first distance and greater than the unloaded length of the corresponding segment of the accompanying support belt, so that the accompanying support belt still maintains axial tension after the tension is released, and the thickness dimension of the plate is greater than the height of the liquid-containing cut when it is not squeezed by the product sheet and the residual material mother plate.

[0011] Furthermore, the sliding clamping mechanism causes the accompanying support belt to move between a clearance position and a support position along the thickness direction of the plate; the clearance position is located below the cutting plane, and the support position is located within the liquid-containing kerf on the cut side of the horizontal cutting section, with the accompanying support belt abutting against the lower surface of the product sheet at the support position.

[0012] Furthermore, the sliding clamping mechanism is connected to a follower mechanism. The guide rod of the follower mechanism is arranged along the plate thickness direction. The follower plate is slidably disposed on the guide rod and connected to the lifting part of the annular wire saw. The linear slide rail arranged along the extension direction of the follower support belt is connected to the follower plate through a connecting sleeve rod. The sliding clamping mechanism is slidably disposed on the linear slide rail. When the annular wire saw is raised and lowered, the follower plate drives the linear slide rail and the sliding clamping mechanism to move synchronously along the plate thickness direction through the connecting sleeve rod. When the stretching mechanism adjusts the clamping distance, at least one side of the sliding clamping mechanism moves along the linear slide rail.

[0013] Furthermore, each of the sliding clamping mechanisms uses a limiting sliding rod arranged along the feed direction as a guide for the movement of multiple sliding clamps. One end of the limiting sliding rod is connected to a fixed end block, and a fixed clamp is fixedly disposed on the limiting sliding rod. Multiple sliding clamps are arranged along the limiting sliding rod and slide in cooperation with it. The corresponding sliding clamps on both sides are respectively maintained at both ends of the same accompanying support belt. The limiting platform is located on the movement path of the sliding clamp, and its ball-head plunger cooperates with the limiting part and guide slope at the bottom of the sliding clamp to form a release limit for the sliding clamp. The sliding clamping mechanisms on both sides are respectively connected to a traction module. The traction module is connected to the feed platform through a traction line. The effective traction length of the traction lines on both sides is set to be the same, so that the corresponding traction modules on both sides enter the traction state during the same displacement stage of the feed platform.

[0014] Furthermore, a sliding clamping seat connected to the end of the accompanying support belt is slidably disposed on the base plate of the sliding clamp along the thickness direction. The stepped shaft passes through the base plate along the thickness direction, and its shoulder and the limiting ring disposed at the upper end abut against the lower and upper sides of the sliding clamping seat, respectively. The conical ring is slidably disposed on the base plate in a direction perpendicular to the axial direction of the stepped shaft, and its conical surface cooperates with the lower end of the stepped shaft. The two ends of the conical ring are provided with stroke retaining rings. The traction module transmits force sequentially to each of the conical rings through the second pull rope and to each of the base plates through the first pull rope. The second pull rope corresponding to the same sliding clamp is tensioned before the first pull rope, so that the conical ring is first lifted by the stepped shaft and holds the sliding clamping seat. Then, the base plate is pulled by the first pull rope to move along the limiting sliding rod. A compression spring is provided between the base plate and the stepped shaft. After the second pull rope is released, the compression spring pushes the stepped shaft to descend. The stepped shaft drives the sliding clamping seat to descend through the limiting ring, and the conical ring is pushed back to its original position by its lower end through the conical surface.

[0015] Furthermore, the stretching mechanism includes a sliding platform, a support wing plate, and a screw drive module; the sliding platform is slidably disposed on the platform base along the extension direction of the accompanying support belt, the support wing plate is disposed on the sliding platform and carries the sliding clamping mechanism on one side, and the sliding clamping mechanism on the other side is fixed relative to the platform base along the extension direction of the accompanying support belt; the screw drive module includes a servo motor and a screw pair driven by the servo motor, the screw pair being hygienically connected to the sliding platform; the controller is electrically connected to the servo motor and is used to control the movement of the sliding platform between the tensioning position that axially stretches the accompanying support belt and the release position that releases a portion of the axial elongation, and to keep the sliding platform in the corresponding position.

[0016] Furthermore, multiple accompanying support belts abutting the lower surface of the product sheet are spaced apart along the feed direction, with the accompanying support belt closest to the horizontal cutting section located on the cut side of the horizontal cutting section and spaced parallel to it; the liquid-containing cut portion between them that is not occupied by the accompanying support belt extends along the extension direction of the accompanying support belt to the two opposite side edges of the sheet to form a liquid and chip removal zone.

[0017] The beneficial effects of this invention are as follows: 1. This invention, by setting up multiple accompanying support belts, a sliding clamping mechanism, and a tensioning mechanism, ensures that the accompanying support belts are axially stretched during the cutting stage, and their dimension along the thickness direction is smaller than the height of the liquid-containing cut. When the feed platform reaches the corresponding traction position, the conical ring, stepped shaft, and sliding clamping seat inside the sliding clamping plate sequentially cause the corresponding accompanying support belt to enter the liquid-containing cut on the cut side and abut against the lower surface of the thin product plate. The sliding clamping plate then moves with the feed platform, thereby avoiding interference with the uncut plate and the horizontal cutting section while forming multi-point flexible support for the gradually expanding cut area.

[0018] 2. After the sheet metal is cut, the present invention reduces the distance between the corresponding clamping positions on both sides through a stretching mechanism, thereby reducing the axial elongation of the accompanying support belt and increasing it back along the sheet thickness direction. The accompanying support belt maintains axial tension and straightness, and abuts against the product sheet and the remaining material mother plate at their respective corresponding positions, forming a local pre-separation gap extending to the side edge of the sheet metal. This provides an initial passage for external air to enter and cutting fluid to exit, thereby reducing the interface separation resistance and the risk of sudden detachment during subsequent lifting. In addition, each accompanying support belt continues to provide spaced bottom support for the product sheet before the suction cup establishes a stable adsorption force, gradually transferring the load on the product sheet from the cutting support state to the adsorption and material removal state. This helps to reduce local deflection and positional disturbance of the product sheet during the suction cup pressing process. Attached Figure Description

[0022] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0023] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 10 As shown, this embodiment provides a cutting device for producing microcrystalline glass plates, used for wet horizontal line cutting of microcrystalline glass plates.

[0025] In this embodiment, the direction in which the feed platform 5 carries the microcrystalline glass plate and moves from the rear to the front of the equipment is the feed direction, the direction in which the feed platform 5 returns to its initial position is the return direction, and the direction perpendicular to the surface of the microcrystalline glass plate is the plate thickness direction. The plane in which the horizontal cutting section of the ring wire saw 3 is located during operation is called the cutting plane, and the side of the plate that has passed through the horizontal cutting section and formed a liquid-containing kerf is called the cut side. The tensioning mechanism 7, the follower mechanism 8, and the limiting sliding rod 92 remain stationary relative to the frame 1 along the feed direction. The sliding clamp 94 only follows within a limited section defined by the limiting sliding rod 92, which is located in front of the horizontal cutting section along the feed direction. The travel of the feed platform 5 crosses the horizontal cutting section and extends to the return position behind the horizontal cutting section.

[0026] The corresponding position of each accompanying support belt 6 is a predetermined position on the sheet metal where support is established by that accompanying support belt 6; the clamping distance on both sides is the distance along the extension direction of the support belt between the corresponding clamping positions of the two sliding clamping mechanisms 9 for the same accompanying support belt 6. When the accompanying support belt 6 is located below the cutting plane and avoids the uncut sheet metal and the horizontal cutting section, it is in the avoidance position; when it enters the liquid-containing cut kerf on the cut side of the horizontal cutting section and abuts against the lower surface of the product sheet, it is in the support position.

[0027] This device includes a frame 1, which serves as the mounting base for the entire equipment. A gantry frame 2 is mounted on the frame 1 to support the ring wire saw 3. A platform base 4 is mounted on the frame 1, and a feed platform 5 is mounted on the platform base 4 to support the microcrystalline glass plate to be processed and to move it along the feed and return directions.

[0028] like Figure 1 As shown, the annular wire saw 3 includes a first cutting wheel 31, a tensioning wheel 32, a drive wheel 33, and a second cutting wheel 34. The annular cutting wire is sequentially wound around each of the wheels, and the lower segment between the first cutting wheel 31 and the second cutting wheel 34 constitutes a horizontal cutting segment. The drive wheel 33 drives the annular cutting wire to circulate, and the tensioning wheel 32 maintains the tension of the annular cutting wire.

[0029] During the cutting process, the feed platform 5 gradually moves the microcrystalline glass plate through the horizontal cutting section and supplies cutting fluid to the cutting area. After the microcrystalline glass plate passes through the horizontal cutting section with the feed platform 5, the portion of the plate above the cutting plane forms the product sheet, and the portion of the plate below the cutting plane and supported by the feed platform 5 forms the scrap mother plate. The narrow space between the product sheet and the scrap mother plate, which has been cut by the horizontal cutting section and contains cutting fluid or cutting powder, is called the liquid-containing kerf. The accompanying support belt 6 only switches positions within the liquid-containing kerf space after being cut by the horizontal cutting section at the corresponding position, without passing through the uncut plate.

[0030] like Figures 3 to 5 As shown, in order to prevent the cut area of ​​the product sheet from losing support during the cutting process, and to prevent the support structure from interfering with the horizontal cut section, this embodiment is provided with multiple accompanying support belts 6.

[0031] Multiple accompanying support belts 6 span between the sliding clamping mechanisms 9 on both sides of the feed platform 5 and are spaced apart along the feed direction. The extension direction of the accompanying support belts 6 is parallel to the horizontal cutting section, and both ends are held by corresponding sliding clamps 94 on both sides, so that the gradually expanding cut area of ​​the product sheet can obtain multiple distributed support positions.

[0032] The accompanying support belt 6 has the deformation characteristic of changing its thickness direction dimension with the axial elongation. In this embodiment, an elastic belt with an elliptical cross-section and resistance to cutting fluid can be used, and the material and cross-sectional dimensions can be selected according to the height of the fluid-containing cut, the required support, and the predetermined axial elongation.

[0033] When the accompanying support belt 6 is subjected to tension along its own extension direction, its axial elongation increases and its dimension along the plate thickness direction decreases, allowing it to enter the liquid-containing cut with a smaller cut height. Under tension, the dimension of the accompanying support belt 6 along the plate thickness direction is smaller than the height of the liquid-containing cut.

[0034] After the sheet metal is cut, the accompanying support belt 6 releases part of its axial elongation, and its dimension along the sheet thickness direction increases as the axial elongation decreases. The accompanying support belt 6 is not completely relaxed, but still maintains axial tension; the axial tension is used to keep the accompanying support belt 6 in a straight state, and the increase along the sheet thickness direction is caused by the decrease in axial elongation.

[0035] The rebound described in this invention refers to the increase in the dimension along the thickness direction of the accompanying support belt 6 after the axial elongation of part is released, and the change in the state of the belt abutting the thin product plate and the residual material mother plate under the restriction of the liquid-containing cut.

[0036] Therefore, the same accompanying support belt 6 enters the liquid-containing cut with a smaller thickness dimension during the cutting stage and supports the thin product plate. After the plate is cut, it increases the thickness dimension by partially releasing tension, thereby forming the cutting support and post-cutting pre-separation functions in sequence on the same structure.

[0037] like Figures 3 to 7 As shown, each sliding clamping mechanism 9 uses a limiting sliding rod 92 as a guide for the movement of multiple sliding clamps 94 along the feed direction. One end of the limiting sliding rod 92 is connected to the fixed end block 91, and the fixed clamp 93 is fixedly mounted on the limiting sliding rod 92 and located at one end of the arrangement of multiple sliding clamps 94. The multiple sliding clamps 94 are slidably mounted on the limiting sliding rod 92 in sequence, and the corresponding sliding clamps 94 on both sides respectively hold the two ends of the same accompanying support belt 6, so that each accompanying support belt 6 can move within a limited section with the corresponding sliding clamp 94.

[0038] Adjacent clamping plates are elastically connected by elastic limiting ropes 96. One section of the elastic limiting rope 96 near the fixed clamping plate 93 connects the fixed clamping plate 93 to the adjacent substrate 941, while the remaining sections connect to two adjacent substrates 941 respectively. When the multiple sliding clamping plates 94 are deployed, the corresponding elastic limiting ropes 96 are stretched, creating opposing constraints on the adjacent substrates 941; during the return convergence process, the elastic limiting ropes 96 retract accordingly, thereby assisting the multiple sliding clamping plates 94 in maintaining their alignment.

[0039] To ensure that each sliding clamp 94 remains in a predetermined position when not under traction, a limiting stage 95 is provided below the movement path of the base plate 941. A ball-head plunger on the limiting stage 95 extends towards the bottom of the base plate 941 and engages with a limiting portion at the bottom of the base plate 941; the limiting portion forms guide ramps on both the contact sides of the base plate 941 during forward and reverse movement. When the base plate 941 is not subjected to an action sufficient to pass over the limiting stage 95, the ball-head plunger provides elastic restraint; when the base plate 941 is under traction or return pressure, the guide ramps compress the ball-head plunger, allowing the base plate 941 to pass over the limiting stage 95, after which the ball-head plunger extends again.

[0040] like Figure 6 and Figure 7As shown, the end of the accompanying support belt 6 is connected to a sliding clamping seat 942 that is slidably disposed on the substrate 941 along the thickness direction. The stepped shaft 943 passes through the substrate 941 along the thickness direction, with its shoulder abutting against the sliding clamping seat 942 from below and its upper end limiting ring 945 abutting against the sliding clamping seat 942 from above, thereby allowing the vertical movement of the stepped shaft 943 to be transmitted to the sliding clamping seat 942. The conical ring 944 is slidably disposed on the substrate 941 in a direction perpendicular to the axial direction of the stepped shaft 943, and engages with the lower end of the stepped shaft 943 through a conical surface; when the conical ring 944 is pulled by the second pull rope 99, its lateral movement is converted into the upward movement of the stepped shaft 943 through the conical surface, and the stepped shaft 943 then pushes the sliding clamping seat 942 and the accompanying support belt 6 upward.

[0041] The travel stop rings at both ends of the conical ring 944 limit its lifting and resetting travel. After the conical ring 944 reaches the end of its lifting travel, the second pull rope 99 remains taut, keeping the sliding clamp 942 at the corresponding height. After the second pull rope 99 is released, the compression spring 946 located between the base plate 941 and the stepped shaft 943 pushes the stepped shaft 943 down, and the limiting ring 945 drives the sliding clamp 942 down synchronously; at the same time, the lower end of the stepped shaft 943 acts on the conical surface of the conical ring 944, causing the conical ring 944 to return to the end of its resetting travel.

[0042] like Figure 2 and Figure 3 As shown, the follower mechanism 8 is connected to the lifting part of the annular wire saw 3, and is used to synchronously change the height position of the sliding clamping mechanism 9 when the annular wire saw 3 adjusts its cutting height. The guide rod 81 is arranged along the plate thickness direction, and the follower plate 82 slides along the guide rod 81 and is connected to the lifting part of the annular wire saw 3; the connecting sleeve rod 83 connects the follower plate 82 to the linear slide rail 84 arranged along the extension direction of the follower support belt 6, and the sliding clamping mechanism 9 is slidably arranged on the linear slide rail 84.

[0043] When the ring wire saw 3 adjusts the cutting height along the plate thickness direction, the follower plate 82 drives the linear slide rail 84 and the sliding clamping mechanism 9 to move synchronously through the connecting sleeve rod 83; when the tensioning mechanism 7 adjusts the clamping distance on both sides, the sliding clamping mechanism 9 on the movable side can move along the linear slide rail 84. Therefore, the overall height adjustment of the sliding clamping mechanism 9 and the clamping distance adjustment on both sides can be performed separately. The individual switching between the avoidance position and the support position of each follower support belt 6 is completed by the cooperation of the cone ring 944, the stepped shaft 943 and the sliding clamping seat 942 in the sliding clamping plate 94, and the movement of the base plate 941 along the limiting sliding rod 92 provides the limited follower stroke required for the follower support belt 6 to move with the feed platform 5.

[0044] like Figure 1 and Figure 3As shown, the tensioning mechanism 7 includes a sliding platform 71, a support wing plate 72, and a screw drive module 73. The sliding platform 71 is slidably disposed on the platform base 4 along the extension direction of the accompanying support belt 6. The support wing plate 72 is disposed on the sliding platform 71 and carries a sliding clamping mechanism 9 on one side. The sliding clamping mechanism 9 on the other side is fixedly disposed relative to the platform base 4 along the extension direction of the accompanying support belt 6. The screw drive module 73 includes a servo motor and a screw pair driven by the servo motor. The screw pair is drively connected to the sliding platform 71. The controller is electrically connected to the servo motor and is provided with position control parameters corresponding to the tensioning position and the release position, respectively, to control the sliding platform 71 to move to the corresponding position and maintain it at the corresponding position; the controller is not shown in the figure. The first distance between the corresponding clamping positions on both sides under the tensioning position is L1, the second distance under the release position is L2, and the unloaded length of the corresponding belt segment is L0, and L1 > L2 > L0 are satisfied.

[0045] like Figure 4 , Figure 5 and Figure 8As shown, traction modules 98 are provided on both sides of the feed platform 5. Each traction module 98 includes a traction frame 981, a reel 982, a limiting shaft 983, a guide ring 984, and a traction line 985. The traction frame 981 is slidably engaged with a limiting sliding rod 92 on the same side. The reel 982 is mounted on the traction frame 981, and the guide ring 984 limits the direction of the traction line 985. One end of the traction line 985 is fixedly connected to the feed platform 5, and the other end passes through the guide ring 984 and is wound around and fixed to the reel 982. Releasing the limiting shaft 983 from the reel 982 and rotating the reel 982 changes the winding amount and reserved traction length of the traction line 985. After adjustment, the limiting shaft 983 restricts the rotation of the reel 982. Therefore, based on the dimensions of the sheet material along the feed direction, the displacement node at which the feed platform 5 moves allows the traction line 985 to begin transmitting traction to the traction frame 981. Since the tensioning mechanism 7, the follower mechanism 8, and the limiting sliding rod 92 remain stationary relative to the frame 1 along the feed direction, the movable sections of the traction frame 981 and the sliding clamp 94 are located in front of the horizontal cutting section along the feed direction. The moving range of the feed platform 5 spans the horizontal cutting section, allowing the traction line fixing point on the feed platform 5 to move from one side of the traction module 98 to the other during a complete reciprocating stroke, passing the traction reversal position corresponding to the traction module 98, and then re-tightening the traction line 985 in the opposite direction after passing. The traction lines 985 on both sides adopt corresponding routing methods, and the adjusted effective traction length is set to be the same, so that the corresponding traction modules 98 on both sides enter the traction state during the same feed displacement stage of the feed platform 5. The corresponding force transmission rope segments of the first pull rope 97 and the second pull rope 99 on both sides adopt corresponding installation lengths and reserved clearances, so that the corresponding sliding clamp seats 942 at both ends of the same following support belt 6 enter the lifting state during the same feed displacement stage, and the corresponding sliding clamps 94 on both sides enter the following state during the same feed displacement stage.

[0046] Working principle: Before cutting begins, the feed platform 5 is in its initial position at the rear of the equipment. Multiple sliding clamps 94 converge on one side of the fixed clamp 93, each conical ring 944 is at the end of its reset stroke, and each accompanying support belt 6 is in a clearance position. The amount of winding of the traction line 985 on the pulley 982 is adjusted according to the size of the material to be processed, and the adjustment state is maintained by the limit shaft 983. The controller controls the lead screw drive module 73 to move the sliding platform 71 to the tensioning position and hold it there, thereby putting the multiple accompanying support belts 6 in an axially stretched state. Subsequently, the feed platform 5 carries the material and feeds it from the rear to the front of the equipment, and the horizontal cutting section of the ring wire saw 3 performs a horizontal wire cut on the material.

[0047] The first pull rope 97 is arranged along the arrangement direction of the sliding clamps 94, forming multiple force-transmitting rope segments corresponding to each base plate 941; the second pull rope 99 is arranged along the same arrangement direction, forming multiple force-transmitting rope segments corresponding to each conical ring 944. Each force-transmitting rope segment has a preset installation length and reserved clearance, so that when the traction module 98 moves along the feed direction, the force-transmitting rope segments corresponding to each sliding clamp 94 change from a slack state to a tensioned force-transmitting state in a predetermined sequence; wherein, the second pull rope 99 corresponding to the same sliding clamp 94 enters the tensioned force-transmitting state before the first pull rope 97.

[0048] like Figure 10 As shown, when the feed platform 5 moves to the traction position corresponding to a certain accompanying support belt 6, the traction module 98 first puts the corresponding second pull rope 99 into a tensioned force transmission state. The second pull rope 99 pulls the corresponding cone ring 944, causing the stepped shaft 943 and the sliding clamp seat 942 to rise, and causing the accompanying support belt 6, which is in a stretched state, to move from the avoidance position to the support position abutting the lower surface of the product sheet within the formed liquid-containing cut; the second pull rope 99 continues to maintain tension. Subsequently, the corresponding first pull rope 97 transmits traction to the base plate 941. The guide slope at the bottom of the base plate 941 presses the ball plunger to retract, causing the sliding clamp 94 to pass over the limiting platform 95 and move along the limiting sliding rod 92 with the feed platform 5. The effective length relationship of adjacent rope segments ensures that each subsequent sliding clamp 94 completes the lifting and following operation in sequence when the feed platform 5 reaches the traction position corresponding to the corresponding accompanying support belt 6.

[0049] After the sheet is completely cut and before the product sheet is unloaded, the controller controls the lead screw drive module 73 to drive the sliding platform 71 from the tensioning position to the release position and maintain it according to the cutting cycle command, so that the distance between the corresponding clamping positions on both sides decreases from L1 to L2. The axial elongation of the accompanying support belt 6 decreases accordingly, and its dimension along the thickness direction increases again; since L2 is still greater than the unloaded length L0 of the corresponding belt segment, the accompanying support belt 6 continues to maintain axial tension and straightness. In the released state, the dimension of the uncompressed accompanying support belt 6 along the thickness direction is greater than the height of the liquid-containing cut, so it is squeezed by the product sheet and the remaining mother plate in the liquid-containing cut, and local pre-separation gaps extending along the accompanying support belt 6 to the side edge of the sheet are formed at the corresponding positions of each accompanying support belt 6. Figure 10 The up and down arrows at the bottom indicate the direction of the contact force exerted by the accompanying support belt 6 on the product sheet and the scrap mother plate, respectively. They do not necessarily mean that the product sheet and the scrap mother plate will move up and down respectively.

[0050] like Figure 8 and Figure 9As shown, the accompanying support belt 6, located in the support position and closest to the horizontal cutting section, is arranged parallel to and spaced apart from the horizontal cutting section. The liquid-containing cut section between them is not occupied by the accompanying support belt 6, and extends along the extension direction of the accompanying support belt 6 to the two opposite side edges of the plate, thereby forming a liquid and chip drainage zone. Cutting fluid and chips can be discharged to the side edges of the plate through the liquid and chip drainage zone. After the plate is completely cut and a local pre-separation gap is formed, outside air can enter the corresponding gap from the side edge of the plate, and cutting fluid can be discharged to the side edge of the plate.

[0051] After the sheet metal is completely cut, the residual cutting fluid between the thin product sheet and the remaining mother plate forms a liquid-containing interface. When the robot arm picks up the material upwards using the suction cup, the thin product sheet needs to be separated from this liquid-containing interface. Before a separation opening is formed at the liquid-containing interface, the cutting fluid between the thin product sheet and the remaining mother plate needs to flow during the initial lifting of the suction cup, and it is difficult for outside air to replenish the space between them in time, thus creating significant interface separation resistance. Therefore, this device partially releases the tension of the accompanying support belt 6 before the suction cup descends, and utilizes the dimensional recovery of the accompanying support belt 6 along the thickness direction of the sheet to first form a local pre-separation gap between the thin product sheet and the remaining mother plate that communicates with the side edge of the sheet metal, establishing a separation starting point for the subsequent lifting of the suction cup.

[0052] Specifically, the stretching mechanism 7 reduces the clamping distance between the sliding clamping mechanisms 9 on both sides, thereby reducing the axial stretch of each accompanying support belt 6 and increasing it back along the thickness direction. After the accompanying support belt 6 is released, it still maintains axial tension and straightness, and its dimension along the thickness direction when not compressed is greater than the distance between the product sheet and the scrap mother plate. During the recovery process of the accompanying support belt 6, its lower side abuts against the scrap mother plate supported by the feeding platform 5, and the downward dimension recovery is restricted. The subsequent recovery action is transmitted to the product sheet through the upper side of the accompanying support belt 6, causing the product sheet to be locally lifted at the corresponding position of the accompanying support belt 6, forming a local pre-separation gap extending along the accompanying support belt 6 to the side edge of the sheet.

[0053] When the robotic arm lowers the suction cup and presses it against the upper surface of the product sheet, the downward load applied by the suction cup is transmitted sequentially through the product sheet, the accompanying support belt 6, and the residual material mother plate to the feeding platform 5, providing bottom support for the product sheet during the pressure deformation of the suction cup seal. After the suction cup forms a seal and establishes a negative pressure that meets the material handling requirements, the robotic arm moves the product sheet upward. The local pre-separation gap provides a pathway for external air to enter between the product sheet and the residual material mother plate, as well as for cutting fluid to flow to the side edge of the sheet, allowing the liquid-containing interface to gradually separate from the already opened position. This helps reduce the concentrated effect of interface resistance during the initial lifting of the suction cup and the positional disturbance caused by the sudden detachment of the product sheet.

[0054] After the product sheet is cut, the feed platform 5 continues to return from the front to the rear of the equipment. In the initial stage of the return, the traction line 985 between the feed platform 5 and the traction module 98 becomes slack. As the feed platform 5 continues to cross the horizontal cutting section and moves to the return section behind the horizontal cutting section, the fixing point of the traction line on the feed platform 5 moves from one side of the traction module 98 to the other side and passes the traction reversal position. The traction line 985 then tightens again in the opposite direction, thereby pulling the traction frame 981 back to its original position. During the return stroke of the traction frame 981, the first pull rope 97 and the second pull rope 99 are released from tension. After the second pull rope 99 is released from tension, the compression spring 946 pushes the stepped shaft 943 down, and the limiting ring 945 drives the sliding clamp seat 942 down. The lower end of the stepped shaft 943 pushes the conical ring 944 back to the end of the reset stroke via the conical surface, so that the accompanying support belt 6 returns to the avoidance position. The traction frame 981 continues to return and pushes each base plate 941 sequentially towards the fixed clamp plate 93. Each base plate 941 retracts by pressing the ball plunger through its bottom guide slope and moves in the opposite direction past the limiting platform 95. The elastic limiting rope 96 retracts and assists the multiple sliding clamp plates 94 to regroup. The controller then puts the stretching mechanism 7 into the initial state required for the next cutting cycle.

[0055] The above embodiments are used to illustrate the structural fit and working process of the present invention. Those skilled in the art can adaptively adjust the corresponding structural dimensions, material parameters, and motion parameters according to actual processing conditions without departing from the technical concept of the present invention.
