Description

Technical Field

[0001] This invention relates to the field of ribbon cutting technology, and more specifically to a ribbon laser cutting device. Background Technology

[0002] Cutting is a crucial step in the production and processing of webbing, and laser cutting, with its advantages of high precision and non-contact processing, is increasingly being applied in this field. Laser cutting guns can generate high-energy-density laser beams, precisely cutting the webbing and achieving good edge sealing. However, in practical applications, laser cutting guns generate a significant amount of heat during prolonged operation, causing the equipment temperature to rise and affecting cutting accuracy and equipment lifespan. Simultaneously, impurities accumulate on the cutting tip of the laser cutting gun over time, impacting laser output and cutting quality. Furthermore, the cut edges of the webbing require auxiliary airflow for cleaning to achieve better separation and cooling.

[0003] While current ribbon laser cutting devices on the market possess cooling and air-purifying structures, these structures lack coordination and integration, resulting in significant space requirements and inconvenient cleaning and maintenance. Therefore, there is an urgent need to develop a ribbon laser cutting device with effective cooling, convenient cleaning, and auxiliary cutting functions. Summary of the Invention

[0004] This invention provides a ribbon laser cutting device that integrates air jetting, cooling, and cleaning structures in a coordinated manner on a laser cutting gun, reducing the space occupied by the above-mentioned traditional structures and improving the cleaning and laser cutting effect of the ribbon.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] In a first aspect, a ribbon laser cutting device includes a body and an XY-axis moving platform mounted on the body. A laser cutting gun is connected to the XY-axis moving platform. A ribbon guiding assembly is disposed between the body and the laser cutting gun. A ribbon conveying assembly is disposed on the body, and the ribbon conveying assembly is located behind the ribbon guiding assembly. The device further includes:

[0007] The cooling section is located on the outside of the laser cutting gun. It includes a liquid guide that is wrapped and connected to the outside of the laser cutting gun and used for the flow of alcohol. The liquid guide is used to contain alcohol and make the alcohol contact the outer wall of the laser cutting gun to absorb heat and achieve cooling. It also includes an auxiliary component that penetrates the liquid guide and is used to deliver alcohol into the liquid guide and discharge the alcohol after absorbing heat to achieve circulating cooling.

[0008] The wiping section is rotatably disposed on the outside of the cooling section. It includes a wiping support that is rotatably connected to the liquid guide and used to dip into alcohol. The wiping support is used to rotate and move the wiping cloth to the end of the laser cutting gun for wiping and cleaning. It also includes an absorbent that penetrates the liquid guide and is used to absorb and store alcohol for the wiping support to dip into.

[0009] The air jet section is provided through the wiping section. It includes a through-bracing member, a tight connector for transmitting gas, the tight connector for keeping the gas passage sealed when the wiping member rotates, and a guide jet member connected to the tight connector for discharging gas. The guide jet member is used to spray gas toward the cutting area to blow away the cut webbing and assist in cooling.

[0010] Furthermore, the liquid guiding component includes a storage sleeve fitted on the outside of the laser cutting gun to form an alcohol flow cavity, and a spiral plate fixed to the inner wall of the storage sleeve and connected to the outer wall of the laser cutting gun. The spiral plate is used to guide the alcohol to flow spirally along the outer wall of the laser cutting gun to increase the contact time and cooling effect.

[0011] Furthermore, the auxiliary components include a liquid connector that passes through the upper end of the storage sleeve and is used for inputting alcohol, a support ring that is fixed on the outside of the storage sleeve and is used to support the rotating component, and a connecting pipe that is provided with one end passing through one side of the storage sleeve and located near the lower end of the storage sleeve, and the other end passing through the upper end of the support ring. The connecting pipe is used to discharge alcohol from the storage sleeve and avoid affecting the rotation of the support component.

[0012] Furthermore, the wiping component includes a rotating ring rotatably connected to the outside of the support ring via a bearing for achieving rotational movement; a support rod fixed to one side of the rotating ring via a connecting component for providing an operating force point; a pushing and wiping part raised and lowered below the support rod for supporting the wiping cloth and achieving the wiping action; and a through hole through the support rod for guiding the raising and lowering of the pushing and wiping part. The pushing and wiping part can be raised and lowered along the through hole to adjust its contact state with the laser cutting gun.

[0013] Furthermore, the pushing and wiping component includes a push plate that is translatably disposed below the support rod for supporting and transmitting motion, a support plate fixed to one end of the push plate near the laser cutting gun, and a wiping cloth fixed on the support plate for directly wiping the lower end face of the laser cutting gun. The wiping cloth contacts the end of the laser cutting gun when the push plate moves and achieves wiping and cleaning by rotating.

[0014] Furthermore, the absorbent includes an arcuate channel at the lower end of the storage sleeve for accommodating the sponge, guide channels on the inner walls of both sides of the arcuate channel for guiding the movement of the protective component, a sponge that penetrates the inner bottom wall of the storage sleeve and extends into the arcuate channel for absorbing and releasing alcohol, and a protective component that is movably disposed at the lower end of the storage sleeve for covering and sealing the sponge. The protective component can move along the guide channels to open or close the sponge for the wiping component to absorb alcohol.

[0015] Furthermore, the sealing component includes an adhesive strip disposed on the inner side of the guide channel for providing a sealing fit, an arc plate disposed on the inner side of the arc channel, connected to the adhesive strip on both sides and located below the sponge for covering the sponge, and adhesive pads fixed at both ends of the arc plate for fitting and sealing with the storage sleeve. The arc plate can rotate along the arc channel to expose or cover the sponge.

[0016] Furthermore, the connecting member includes a movable through-bracing rod at its lower end, a T-shaped structure to prevent complete removal from the lower end of the bracing rod, a T-tube for transmitting gas, an opening through the T-tube for accommodating the through-bracing plate, and a sealing component disposed between the push plate and the T-tube to maintain a sealed gas passage. The push plate passes through the opening and cooperates with the sealing component to maintain a sealed state.

[0017] Furthermore, the sealing component includes a sealing ring embedded in the upper center of the push plate, having an upward arcuate protrusion on its top surface to provide a sealing mating surface, and a sealing ring disposed inside the through-hole, having its top surface connected to the T-tube and its bottom surface mating with the arcuate protrusion of the sealing ring to achieve a sealing connection. The bottom surface of the sealing ring has an upward arcuate recess, and the arcuate protrusion and arcuate recess provide positioning and sealing functions when they mate.

[0018] Furthermore, the spray guide includes an air connector connected to the upper end of the T-tube for receiving auxiliary gas, an inner channel that extends through the push plate near the support plate and communicates with the sealing ring for guiding airflow, an opening that extends through the support plate and communicates with the inner channel for connecting the air outlet channel, and an air nozzle located at the lower end of the support plate, extending obliquely towards the vertical line of the laser cutting gun and communicating with the opening for guiding airflow toward the cutting area. The air nozzle sprays air toward the cutting position when the laser cutting gun is working to assist in the separation and cooling of the webbing.

[0019] The above-described solution of the present invention has at least the following beneficial effects:

[0020] By combining a cooling section, a wiping section, and an air jet section, the laser cutting gun achieves effective cooling, convenient cleaning, and auxiliary cutting functions. The cooling section utilizes the spiral flow of alcohol or coolant on the outside of the laser cutting gun to achieve continuous cooling. The wiping section uses a rotatable wiping element in conjunction with an alcohol-soaked wiping cloth to clean the cutting gun tip. The air jet section uses a close-fitting component and a spray guide to spray air into the cutting area to assist in the cutting and cooling of the webbing. The synergistic effect of these three components effectively solves the problems of laser cutting gun overheating, tip contamination, and insufficient cutting assistance, significantly improving cutting accuracy, equipment lifespan, and cutting quality, while reducing the space occupied by the equipment.

[0034] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0035] like Figures 1 to 11 As shown, an embodiment of the present invention provides a ribbon laser cutting device, including a body 1 and an XY-axis moving platform 3 disposed on the body 1. A laser cutting gun 4 is connected to the XY-axis moving platform 3. A ribbon guiding assembly is disposed between the body 1 and the laser cutting gun 4. A ribbon conveying assembly is disposed on the body 1, and the ribbon conveying assembly is located behind the ribbon guiding assembly. The device also includes:

[0036] The cooling section is located on the outside of the laser cutting gun 4. It includes a liquid guide for the flow of alcohol that is wrapped and connected to the outside of the laser cutting gun 4, and an auxiliary component that penetrates the liquid guide to cool the laser cutting gun 4.

[0037] The wiping part is rotatably disposed on the outside of the cooling part. It includes a support wiping part rotatably connected to the liquid guiding part, and a suction wiping part disposed through the liquid guiding part. The suction wiping part is located above the auxiliary part, and the auxiliary part is located above the support wiping part, so that the support wiping part can dip alcohol to wipe the end of the laser cutting gun 4.

[0038] The air jet section is provided through the wiping section, and includes a closely connected member that is provided through the wiping member, and a guide jet member that communicates with the closely connected member for discharging gas, so as to use air jet to assist the laser cutting gun 4 in cutting the webbing.

[0039] It is worth noting that the wiping section and the air spray section do not function simultaneously, but rather function separately at different stages according to the work requirements.

[0040] Specifically, a support cover 2 is fixed on the machine body 1, the XY axis moving platform 3 is located inside the support cover 2, the support cover 2 has a door that rotates upward to open, and the webbing conveyor assembly includes:

[0041] There are two support plates 5, which are symmetrically fixed to the body 1 and located inside the support cover 2;

[0042] The conveyor roller 6 is rotatably connected between the two support plates 5;

[0043] Motor 7 is fixed on one side of one of the support plates 5, and its drive end is connected to the conveyor roller 6;

[0044] Guide groove 8, through support plate 5 is opened;

[0045] The pressure roller 9 is movably positioned above the conveyor roller 6;

[0046] Bolt 10 is installed through the guide groove 8 and is threadedly connected to the pressure roller 9.

[0047] Specifically, the machine body 1 provides stable support for the support cover 2, and the support cover 2 provides protection for its inner side. The XY axis moving platform 3 provides support for the laser cutting gun 4, and under the support of the machine body 1 and the control of the operator, it drives the laser cutting gun 4 to move along the X and Y axes. The support plate 5 provides rotational support for the conveyor roller 6 under the support of the machine body 1, and can stably support the motor 7. After the motor 7 is started, it can drive the conveyor roller 6 to rotate through the drive end. The bolt 10 can use the thread with the pressure roller 9 to press the support plate 5. When the bolt 10 is tightened, the pressure roller 9 can be fixed at the current height. The guide groove 8 provides lifting space for the bolt 10.

[0048] In practical application, the operator can place one end of the webbing to be cut between the conveyor roller 6 and the pressure roller 9 as needed. Simultaneously, the operator pulls one end of the webbing towards the guide assembly for positioning. Then, the operator loosens the bolt 10 and adjusts the pressure roller 9 downwards along the guide groove 8, causing the pressure roller 9 and the conveyor roller 6 to clamp the webbing. The operator then tightens the bolt 10 to position the pressure roller 9. Afterwards, the operator can control the motor 7 to rotate the conveyor roller 6 using its drive end. This allows the conveyor roller 6 and the pressure roller 9 to use rotational power and friction to push the webbing towards the guide assembly. Simultaneously, the operator can control the XY-axis moving platform 3 to move the laser cutting gun 4 along the XY-axis, and simultaneously activate the laser cutting gun 4 to cut the webbing during the translation process.

[0049] The webbing guide assembly includes:

[0050] Support plate 11 is fixed to the body 1 and located below the laser cutting gun 4;

[0051] Track 12 is symmetrically and laterally opened on support plate 11;

[0052] There are two limiting plates 13, which are translatably mounted on the support plate 11 and are guided and connected to the track 12.

[0053] In practical application, the support plate 11 can provide space for the track 12 under the support of the machine body 1. The track 12 can provide movement guidance and positioning for the limiting plate 13. The operator can move the limiting plate 13 along the track 12 according to the actual needs, so that the distance between the two limiting plates 13 can be just enough for the webbing to pass through, thereby providing limiting and movement guidance for the webbing.

[0054] In a preferred embodiment of the present invention, the liquid guiding component includes:

[0055] Storage sleeve 14 is fitted on the outside of laser cutting gun 4;

[0056] The spiral plate 15 is fixed to the inner wall of the storage sleeve 14 and connected to the outer wall of the laser cutting gun 4.

[0057] Specifically, the laser cutting gun 4 can provide stable support for the storage sleeve 14, and the storage sleeve 14 and the laser cutting gun 4 can provide flow space for alcohol. The storage sleeve 14 and the laser cutting gun 4 can provide stable support for the spiral plate 15, and the spiral plate 15 can provide flow guidance for the alcohol, so that the alcohol can flow in a spiral, thereby increasing the flow distance of the alcohol and the contact time between the alcohol and the laser cutting gun 4, so that the alcohol can cool the laser cutting gun 4 during the flow process.

[0058] Auxiliary components include:

[0059] Liquid connector 16 connects to the upper end of the storage sleeve 14;

[0060] Support ring 18 is fixed to the outside of storage sleeve 14;

[0061] The connecting pipe 17 is installed with one end passing through one side of the storage sleeve 14 and positioned close to the lower end of the storage sleeve 14, and the other end passing through the upper end of the support ring 18, so as to avoid affecting the rotation of the support and friction parts.

[0062] Specifically, the storage sleeve 14 provides stable support for the liquid connector 16 and the connecting pipe 17. The liquid connector 16 and the connecting pipe 17 provide a connection position for the pipeline for conveying alcohol, so that alcohol can enter the liquid connector 16 through the pipeline and enter the storage sleeve 14. The alcohol will flow spirally along the spiral plate 15 in the storage sleeve 14 until it is full. Then it will enter the connecting pipe 17 through the storage sleeve 14 and be discharged into the connecting pipe 17.

[0063] In practical application, before using the laser cutting gun 4, the operator can connect the coolant or alcohol supply line to the liquid connector 16 and the connecting pipe 17. This allows the coolant or alcohol to pass through the liquid connector 16 and enter the inner side of the storage sleeve 14. Guided by the spiral plate 15, the coolant or alcohol can spirally flow around the outer side of the laser cutting gun 4 until it fills the entire storage sleeve 14. Finally, it flows out and circulates from the connecting pipe 17. This allows the coolant or alcohol to adhere to the outer wall of the laser cutting gun 4 during its flow within the storage sleeve 14 and absorb heat from the laser cutting gun 4 during the flow to cool it down and prevent the laser cutting gun 4 from overheating.

[0064] In a preferred embodiment of the present invention, the friction support includes:

[0065] The swivel ring 19 is rotatably connected to the outside of the support ring 18 via a bearing;

[0066] The strut 20 is fixed to one side of the swivel ring 19 by a connecting component;

[0067] Through hole 21, through support rod 20 is provided;

[0068] The pushing and rubbing parts are positioned below the support rod 20;

[0069] Specifically, the support ring 18 can provide rotational support for the rotating ring 19 through the bearing, the rotating ring 19 can provide support for the support rod 20 through the fixing component, the support rod 20 can drive the rotating ring 19 to rotate around the bearing as the center under the support of the support ring 18 under the action of external force, and the support rod 20 can provide opening space for the through hole 21.

[0070] The friction parts include:

[0071] Push plate 23 is positioned below support rod 20 by translation;

[0072] Support plate 24 is fixed to one end of push plate 23 near laser cutting gun 4;

[0073] Wiping cloth 25 is fixed on support plate 24.

[0074] Specifically, the push plate 23 can provide stable support for the support plate 24, the support plate 24 can provide support for the wiping cloth 25, and the wiping cloth 25 can wipe the lower end face of the laser cutting gun 4 under the action of external force.

[0075] The suction cups include:

[0076] Arc 26 is located at the lower end of storage sleeve 14;

[0077] Guide channel 32 is located on the inner walls of both sides of the arc channel 26;

[0078] Sponge 31 is provided through the inner bottom wall of the storage sleeve 14 and extends into the arc channel 26;

[0079] The protective components are movable and located at the lower end of the storage sleeve 14.

[0080] Specifically, the storage sleeve 14 can provide opening space for the arc track 26, the arc track 26 can provide moving space for the arc plate 28, the storage sleeve 14 can provide opening space for the arc track 26, the arc track 26 can provide moving guidance for the adhesive strip 27, the storage sleeve 14 can provide stable support for the sponge 31, the sponge 31 can absorb alcohol, and release the absorbed alcohol under the action of external force.

[0081] The protective components include:

[0082] Adhesive strip 27 is installed inside the guide channel 32;

[0083] The arc plate 28 is set inside the arc track 26, and is connected to the adhesive strip 27 on both sides, and is located below the sponge 31;

[0084] The rubber pads 29 are fixed at both ends of the arc plate 28.

[0085] Specifically, the storage sleeve 14 can provide support for the arc plate 28 through the adhesive strip 27, the arc plate 28 can provide support for the adhesive pad 29, and the adhesive pad 29 and adhesive strip 27 can fit together with the storage sleeve 14 around the arc plate 28 to achieve a sealing effect.

[0086] In practical application, according to actual needs, the operator can stop supplying alcohol to the storage sleeve 14, and then use the support rod 20 to push the rotating ring 19 to rotate around the bearing. This allows the support rod 20 to drive the push plate 23 to rotate together through the T-tube 22, so that the support rod 20 rotates to the desired position. Figure 4 At the position shown, the push plate 23 is then vertically lifted upwards under the guidance of the through hole 21, so that the push plate 23 can move upwards along with the wiping cloth 25 via the support plate 24, allowing the wiping cloth 25 to move to the position shown. Figure 7 Inside the arc 26 shown, the support plate 24 will contact one side of the base plate 30. Then, the operator needs to use the support rod 20 to push the rotating ring 19 counterclockwise under the support of the bearing. This causes the support rod 20 to drive the push plate 23 and the support plate 24 to rotate counterclockwise together via the T-tube 22. The support plate 24 can then push the arc plate 28 along the arc 26 counterclockwise around the bearing via the base plate 30. This causes the arc plate 28 to drive the rubber strip 27 and rubber pad 29 to rotate together, thus moving the arc plate 28 away from under the alcohol-absorbing sponge 31. Simultaneously, the push plate 23, during rotation, will drive the wiping cloth 25 to rotate and move under the sponge 31 via the support plate 24, allowing the wiping cloth 25 to contact the bottom surface of the sponge 31 and absorb the alcohol absorbed by the sponge 31. Next, push the push plate 23 vertically downwards to reset the wiping cloth 25. Then, manually push the arc plate 28 along the arc 26 through the base plate 30 to reset and cover the sponge 31. Then, with the support of the T tube 22, the operator can push the push plate 23 towards the support plate 24, so that the push plate 23 can drive the wiping cloth 25 to the lower end face of the laser cutting gun 4 through the support plate 24. Then, push the support ring 18 through the support rod 20 to rotate in one direction around the bearing, so that the support rod 20 can drive the support plate 24 and the wiping cloth 25 to rotate together through the T tube 22 and the push plate 23. This allows the wiping cloth 25 to wipe and clean the laser cutting gun 4 with the alcohol it has soaked in, avoiding excessive alcohol absorption by the wiping cloth 25 and facilitating the wiping and maintenance of the lower end face of the laser cutting gun 4.

[0087] As a preferred embodiment of the present invention, the connecting member includes:

[0088] T-tube 22 is installed through the lower end of the strut 20. Its T-shaped structure can prevent it from completely moving out of the lower end of the strut 20.

[0089] A 38-inch opening is made, through which a 22-inch T-tube is inserted;

[0090] The push plate 23 passes through the through-hole 38;

[0091] The sealing component is located between the push plate 23 and the T-tube 22.

[0092] Specifically, the support rod 20 can provide the T-tube 22 with lifting and moving space and support and limiting function, and the T-tube 22 can provide the opening space for the through hole 38, which can provide the through channel for the push plate 23, so that the T-tube 22 can provide support for the push plate 23.

[0093] Sealing components include:

[0094] The sealing ring 36 is embedded in the upper middle part of the push plate 23, and its top surface has an upward arc-shaped protrusion;

[0095] The sealing ring 34 is provided inside the through-hole 38, and its top surface is connected to the T-tube 22, while its bottom surface is matched with the arc-shaped protrusion of the sealing ring 36.

[0096] The bottom surface of the sealing ring 34 has an upward arc-shaped indentation.

[0097] Specifically, the upward protrusion of the sealing ring 36 and the arc-shaped concaveness of the sealing ring 34 fit together, which can play a role in positioning and sealing. When the sealing ring 36 and the sealing ring 34 move to the fitting position, the arc-shaped protrusion and the arc-shaped concaveness will provide a change in feel, thereby reminding the staff to make sure that the sealing ring 34 and the sealing ring 36 are in place.

[0098] The nozzle guide includes:

[0099] Air connector 33 is connected to the upper end of T-pipe 22;

[0100] The inner channel 35 is opened through the push plate 23 near the support plate 24 and is connected to the sealing ring 36;

[0101] The passage 39 is opened through the branch plate 24 and connects with the inner passage 35;

[0102] The air outlet 37 is located at the lower end of the support plate 24 and extends obliquely towards the vertical line of the laser cutting gun 4, and is connected to the through port 39.

[0103] Specifically, the T-tube 22 provides support for the gas connector 33, which provides a connection position for the gas pipeline and a channel for the gas to enter the T-tube 22. The push plate 23 provides space for the inner channel 35, which provides a channel for the gas in the T-tube 22 to enter the port 39. The support plate 24 provides space for the port 39, which provides a channel for the gas to enter the air outlet 37. The air outlet 37 provides a discharge channel and guides the gas, allowing it to be blown onto the cut webbing immediately after the laser cutting gun 4.

[0104] When the staff pushes the push plate 23, the push plate 23 will move along the through 38 under the action of external force, so that the push plate 23 can drive the sealing ring 36 to move together under the action of external force. The sealing ring 36 will deform by the resistance of the sealing ring 34 and move out of the arc-shaped recess of the sealing ring 34 during the movement, thereby separating from the sealing ring 34, so that the push plate 23 can move smoothly.

[0105] In practical application, before laser cutting, the operator can push or pull the push plate 23 along the through hole 38, causing the push plate 23 to move the sealing ring 36 together. This moves the sealing ring 36 below the sealing ring 34, aligning the arc-shaped protrusion and concave shape. Then, the operator pushes the T-tube 22 upwards along the through hole 21, causing the T-tube 22 to move the gas connector 33 upwards, extending it from the upper end of the support rod 20. The operator can then connect the auxiliary gas supply line to the gas connector 33. Finally, the T-tube 22 is lowered back down, and the... Gas is supplied to the gas connector 33 through the connecting pipe 17, allowing the gas to enter the inner side of the T-pipe 22. The gas then passes through the T-pipe 22 and, with the sealing cooperation of the sealing ring 36 and the sealing ring 34, enters the inner channel 35. The gas then enters the outlet 39 along the inner channel 35, passes through the outlet 39, and enters the air outlet 37. Finally, guided by the air outlet 37, the gas is blown onto the cut webbing. This allows the airflow to push the webbing along with the laser cutting gun 4 during the cutting process, assisting in the separation and cooling of the cut webbing, thus improving the cutting effect and quality.

[0106] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
