Description

Technical Field

[0001] The utility model relates to a laser plate cleaning machine. Background Art

[0002] In the production process of chemical fiber filaments such as polyester filament, a spinning assembly with a spinneret is usually required, and the filament is ejected through several micropores on the spinneret. In order to ensure the spinnability and weight stability of the fiber filament, the spinneret is cleaned regularly to avoid some dirt accumulated during the production process clogging the micropores, causing the equipment to be unable to produce filaments normally. The above cleaning process is also commonly known as "shoveling the plate", which means that the dirt on the spinneret needs to be scraped off by a scraper, thereby removing the monomers produced by high-temperature decomposition or degradation of the polymer on the spinneret, as well as the coke from spraying the release agent (usually silicone oil) when cleaning the plate.

[0003] In order to avoid a series of problems brought about by manual scraping operation, such as high requirements on operators, low production efficiency, impact on operators' health and uneven scraping quality, the existing technology proposes the use of automatic scraping robots for mobile scraping, but the following defects still exist: 1. During the cleaning process, it is still necessary to cooperate with the spraying of silicone oil, which causes pollution, and the silicone oil sprayed on the panel forms coke on the panel, affecting the cleaning effect; 2. When the size of the spinneret panel changes, the size and position of the scraper on the automatic scraping robot need to be adjusted or replaced accordingly, resulting in limited use of the scraping robot; 3. The automatic scraping robot can only run in a single straight direction. When multiple spinning boxes of the spinning assembly are distributed in different directions, multiple scraping robots need to be configured or the scraping robots need to be switched manually, which wastes manpower and affects the overall production efficiency.

[0052] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present application so that the advantages and features of the present invention can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only part of the embodiments of the present application, not all of them.

[0053] See also Figures 1 to 15 A laser plate cleaning machine is shown, which is used to clean the spinneret plate 102 of the spinning assembly 100, wherein Figure 2 As shown, the spinning assembly 100 has a spinning manifold 101, a spinneret panel 102 is arranged on the upper part of the spinning manifold 101, and a plurality of spinneret holes 103 are arranged on the spinneret panel 102, each of which is provided with densely distributed micro-holes for spinning out. The laser plate cleaning machine is mainly used to clean each spinneret hole 103 on the spinneret panel 102 to prevent dirt from clogging the micro-holes and affecting the spinning.

[0054] The laser plate cleaning machine includes a laser cleaning device, which includes a laser host 3, a laser working head 5 and a mechanical arm 4. The laser working head 5 is connected to the laser host 3 through an optical fiber. The laser working head 5 has a light outlet 52 facing the spinneret panel 102. The mechanical arm 4 has a mounting end 41 and a free end 42 respectively arranged at two different ends of its own length direction. The laser working head 5 is installed on the free end 42 and moves with the mechanical arm 4.

[0055] The laser plate cleaning machine also includes a guide carrier, which includes a guide rail 22 and a mounting seat 1. The laser cleaning device is installed on the mounting seat 1. The mounting seat 1 is suspended on the guide rail 22 and can move along the guide rail 22, thereby carrying the laser cleaning device to move along the length extension direction of the guide rail 22 to move relative to the length extension direction of the spinneret panel 102 of the spinning assembly 100.

[0056] When the laser cleaning machine is working, the laser host 3 works, and the laser beam is projected outward from the light outlet 52 of the laser working head 5 to act on the spinneret panel 102. The mechanical arm 4 moves with the laser working head 5 to change the relative position between the laser working head 5 and the spinneret panel 102, so that different positions in the width direction of the spinneret panel 102 can be projected with the laser beam to achieve cleaning; at the same time, the laser cleaning device as a whole moves along the guide rail 22 and moves relative to the spinneret panel 102, so as to continuously clean the spinneret panel 102 along the length direction of the spinneret panel 102. In this cleaning process, the laser is directly used to clean the dirt on the spinneret panel 102, and the silicone oil used in the traditional cleaning process does not need to be used, there is no pollution, and it has a better cleaning effect; and the laser working head 5 moves with the mechanical arm 4 relative to the spinneret panel 102, which can be applied to the cleaning of spinnerets 102 of different sizes and positions. When the position and size of the spinneret panel 102 are adjusted, there is no need to replace the components on the laser cleaning machine.

[0057] As shown in the drawings, in this embodiment, the guide carrier device further includes a rack 23, a gear 6 and a driving member 60. The rack 23 and the guide rail 22 are relatively fixedly arranged. The rack 23 and the guide rail 22 are spaced apart in the horizontal direction, and the spacing between the rack 23 and the guide rail 22 is a constant value. The gear 6 can be arranged to rotate around its own axis. The driving member 60 is specifically a motor. The gear 6 and the driving member 60 are both arranged on the mounting seat 1, and the gear 6 and the rack 23 are meshed with each other. When the driving member 60 drives the gear 6 to rotate, the gear 6 and the rack 23 are meshed with each other, and the mounting seat 1 will be driven to automatically move along the guide rail 22 with the laser cleaning device.

[0058] As shown in the drawings, the guide and carrier device further includes a fixed frame 21, a rack 23 and a guide rail 22 are respectively fixed at the bottom of the fixed frame 21, and the rack 23 has a tooth portion that cooperates with the gear 6, and the tooth portion is arranged on the side of the rack 23 away from the guide rail 22. In this arrangement, on the one hand, the gear 6 can be arranged on the side of the rack 23 away from the guide rail 22, so that only a small gap is left between the guide rail 22 and the rack 23, so that the size of the fixed frame 21 does not need to be too large; on the other hand, after the gear 6 and the rack 23 cooperate with each other, the rack 23 can withstand a certain lateral force to a certain extent, so that the force during the sliding fit connection between the guide rail 22 and the laser cleaning device is reduced, so that the laser cleaning device can move along the guide rail 22 more smoothly.

[0059] A plurality of fixing seats 25 are fixedly arranged on the above-mentioned fixing frame 21, and a crossbeam 200 is arranged on the top of the spinning workshop, and the fixing frame 21 is fixed to the crossbeam 200 through the plurality of fixing seats 25, so that the fixing frame 21 and the guide rail 22 are suspended on the upper part of the workshop to form a ceiling rail assembly 2; the laser cleaning device is correspondingly suspended in the upper space of the workshop. The spinning box 101 of the spinning assembly 100 can be arranged along the ceiling rail assembly 2 in the workshop, specifically so that the length extension direction of the spinneret panel 102 is arranged as parallel as possible to the length extension direction of the guide rail 22. In this way, the laser cleaning device will not be affected by the waste silk and other objects on the ground during operation, and can move in the air without obstacles, safely and stably. At the same time, when used for cleaning processing of the existing spinning assembly 100, it is only necessary to hang and install the ceiling rail assembly 2 in the corresponding spinning workshop so that the guide rail 22 is arranged along the length extension direction of the spinneret panel 102, and then connect the mounting seat 1 to the ceiling rail assembly 2, and then install the laser cleaning device on the mounting seat 1. There is no need to change or set up the spinning assembly 100, which is convenient for installation and use.

[0060] The overhead rail assembly 2 also includes a power supply busbar 24, in which a conductive member extending along the length direction is provided, and the power supply busbar 24 is connected to a power source. The power line on the laser cleaning device is kept connected to the conductive member in the power supply busbar 24 in a sliding manner, so that when the laser cleaning device moves along the guide rail 22, its power line is always electrically connected to the power supply busbar 24. In this way, the laser cleaning device can move freely in the spinning workshop without being restricted by the need to connect the power line to the power supply.

[0061] See also Figures 3 to 6 As shown, the guide carrier device also includes a first guide assembly 7 having a first guide seat 71, and the first guide seat 71 can be rotatably arranged on the mounting seat 1 around a first axis (not shown in the figure), and the first axis extends in the vertical direction. The first guide assembly 7 has more than two groups arranged at intervals, and all the first guide seats 71 are connected to the guide rail 22 in a sliding manner. In this way, multiple first guide seats 71 are installed in a sliding manner with the guide rail 22 at the same time, and the weight of the laser cleaning device is loaded at the same time; at the same time, when there is a curved part in the length extension direction of the guide rail 22, the first guide seat 71 rotates around the first axis when running to the curved part, thereby ensuring that multiple first guide seats 71 are in stable sliding cooperation with the guide rail 22 at the same time, ensuring that the mounting seat 1 as a whole can slide smoothly along the length extension direction of the guide rail 22 without getting stuck.

[0062] Specifically, see Fig.12As shown, each first guide seat 71 includes a rotating portion 7a and a sliding fitting portion 7b which are fixed to each other. The sliding fitting portion 7b is provided with a guide groove which cooperates with the guide rail 22. The cross-section of the guide rail 22 is in the shape of an "I". The guide groove can allow the guide rail 22 to be inserted along the length direction, so that it is connected to the guide rail 22 in a hanging manner; the rotating portion 7a is rotatably connected to the mounting seat 1, and a bearing is provided between the two.

[0063] See also Figures 3 to 15 As shown, the guide carrier device also includes a second guide assembly 8, which has a second guide seat 82 and a sliding seat 81. The second guide seat 82 can be rotatably arranged on the sliding seat 81 around the second axis. The second guide assembly 8 and all the first guide assemblies 7 are spaced apart from each other in the first direction. The sliding seat 81 can be slidably arranged on the mounting seat 1 along the second direction. The second guide seat 82 is connected to the guide rail 22 in a sliding manner. The first axis and the second axis are parallel to each other, and the first direction, the second direction and the first axis / the second axis are perpendicular to each other. The gear 6 can be rotatably connected to the sliding seat 81 around its own axis. Correspondingly, the driving member 60 is also arranged on the sliding seat 81. The structure of the second guide seat 82 and its matching connection method with the guide rail 22 are similar to those of the first guide seat 71, and will not be repeated here.

[0064] During the movement of the mounting seat 1 along the length direction of the guide rail 22, when the gear 6 runs to the curved part of the guide rail 22, the sliding seat 81 slides relative to the mounting seat 1 along the second direction, so that the distance between the gear 6 and the rack 23 is adjusted accordingly, so that the gear 6 can always maintain the meshing with the rack 23, avoiding the gear 6 from being disengaged from the rack 23, thereby ensuring the automatic movement of the laser cleaning device along the entire length extension direction of the guide rail 22.

[0065] As shown in the accompanying drawings, in this embodiment, the guide rail 22 has a first straight extension segment 22a, a curved extension segment 22c and a second straight extension segment 22b which are connected in sequence along the length extension direction. The length extension direction of the first straight extension segment 22a and the length extension direction of the second straight extension segment 22b are perpendicular to each other, and the length extension trajectory of the curved extension segment 22c extends in an arc shape, wherein the first extension line where the first straight extension segment 22a is located and the second extension line where the second straight extension segment 22b is located are respectively tangent to the arc extension line of the curved extension segment 22c.

[0066] The above-mentioned curved extension section 22c is mainly set to achieve a transition connection between the first straight extension section 22a and the second straight extension section 22b. When setting it specifically, it should be ensured that during the movement of the mounting seat 1 along the guide rail 22, at most only two guide seats among all the first guide seats 71 and the second guide seats 72 are located on the curved extension section 22c at the same time.

[0067] When the second guide seat 82 cooperates with the first straight extension section 22a, the first direction extends along the length direction of the first straight extension section 22a, and the second direction is perpendicular to the length direction of the first straight extension section 22a; when the second guide seat 82 cooperates with the second straight extension section 22b, the first direction extends along the length direction of the second straight extension section 22b, and the second direction is perpendicular to the length direction of the second straight extension section 22b; and when the second guide seat 82 cooperates with the curved extension section 22c, the second direction extends radially along the arc extension trajectory where the curved extension section 22c is located.

[0068] When the second guide seat 82 cooperates with the first straight extension section 22a or the second straight extension section 22b, the sliding seat 81 does not need to move in the second direction, and the gear 6 can maintain meshing with the rack 23 corresponding to the straight extension section; and when the second guide seat 82 cooperates with the curved extension section 22c, the sliding seat 81 slides in the second direction, which is a radial movement along the curved extension section 22c, so that the gear 6 moves toward or away from the rack 23, thereby ensuring that the gear 6 and the rack 23 maintain a stable meshing state and do not disengage or get stuck. In this way, the spinning assembly 100 can include a plurality of spinning manifolds 101, and the plurality of spinning manifolds 101 can be distributed along the first straight extension section 22a and along the second straight extension section 22b, so that the spinnerets 102 on the spinning manifolds 101 at different positions in the spinning workshop can be cleaned by a set of laser cleaning machines, which facilitates the layout and space utilization of the spinning assembly 100 in the workshop and saves the number of laser cleaning machines.

[0069] Here, see Fig.12 As shown, two groups of guide members 83 are also provided on the mounting seat 1, which are specifically guide rail members. The two groups of guide members 83 extend along the second direction and are arranged at intervals. The two side portions of the sliding seat 81 are respectively slidably matched with the above-mentioned two groups of guide members 83 to improve the stability and accuracy of sliding. The motor as the driving member 60 is installed below the sliding seat 81, and the gear 6 is located above the sliding seat 81, with its axis extending in the vertical direction, and the rack 23 corresponds to the curved portion of the curved extension section 22c, and its tooth portion is arranged on the side of the curved portion that arches outward.

[0070] The second guide assembly 8 is arranged between two groups of first guide assemblies 7. When passing through the curved extension section 22c, under the action of the first guide seats 71 on both sides, the second guide seat 82 keeps cooperating with the guide rail 22, and moves the sliding seat 81 and the gear 6 thereon toward or away from the guide rail 22, so that the gear 6 and the rack 23 always keep in meshing, thereby making the mounting seat 1 as a whole more stable and reliable when automatically running along the length extension direction of the guide rail 22.

[0071] As shown in the accompanying drawings, in this embodiment, the mounting base 1 includes a first support 11 and a second support 12 fixedly connected by a rigid connector 13, the laser host 3 is suspended and installed on the first support 11, and the robot arm 4 is suspended and installed on the second support 12, wherein the laser host 3 is box-shaped as a whole and has a large overall weight, and the mounting end 41 of the robot arm 4 is connected to the second support 12.

[0072] At least two groups of first guide components 7 are respectively provided on the first support 11 and the second support 12, and the second guide component 8 is provided on the first support 11 and is provided between the two groups of first guide components 7 on the first support 11. In this way, not only the length of the first support 11 is fully utilized, but also the motor of the driving member 60 is connected to the power line of the laser host 3 together, which is convenient for line layout.

[0073] The guide bearing device also has a positioning bar (not shown in the figure), which is arranged along the length extension direction of the guide rail 22. The laser cleaning device is also provided with a scanner for obtaining position information on the positioning bar, and the scanner is connected to the drive member 60 in the guide carrier. Since the position of the guide rail 22 relative to the spinneret 102 is fixed, the position information on the positioning bar corresponds to the position information on the length extension direction of the spinneret 102. According to the position information on the positioning bar obtained by the scanner, the corresponding position on the spinneret 102 can be known. The drive member 60 controls the drive member 60 to drive the gear 6 to rotate a specified number of revolutions according to the current position information and the target position information, so that the laser cleaning device can move to the target position along the guide rail 22, which enables the entire laser cleaning device to be positioned on the guide rail 22, and realizes the correction of the laser cleaning device after running for a period of time, thereby ensuring the processing accuracy. In the specific setting, the positioning bar can be fixed to the guide rail 22 or the fixed frame 21 by pasting, and the scanner can be set on the upper part of the laser host 3.

[0074] See the accompanying drawings, especially Figure 7 , Figure 8 As shown, the laser working head 5 includes a body 51, which is mounted on the mechanical arm 4. A connecting seat 50 is provided at the bottom of the body 51, and the connecting seat 50 can be detachably connected with the free end 42 of the mechanical arm 4. A connecting terminal 54 is also provided on one side of the body 51 to connect with the laser host 3 through an optical fiber cable; a light outlet channel (not shown in the figure) for projecting a laser beam is provided on the body 51, and a light outlet 52 is located at one end of the light outlet channel.

[0075] The laser working head 5 also includes a purge assembly, which is used to blow out an airflow containing positive and negative ions. The purge assembly is arranged on the body 51 and has an air outlet 53. Here, the air outlet 53 is a plurality of small holes distributed at intervals. When the laser working head 5 cooperates with the spinneret panel 102 for processing, the air outlet 53 and the light outlet 52 are both upwardly directed toward the spinneret panel 102. Specifically, the purge assembly includes a blower and an ion generator capable of generating positive and negative ions. The blower and the ion generator are both arranged in the inner cavity of the body 51, wherein the blower is configured to blow out the positive and negative ions generated by the ion generator through the above-mentioned air outlet 53.

[0076] In this way, before or during the laser cleaning of dirt on the spinneret panel 102, by blowing a gas flow containing positive and negative ions toward the spinneret panel 102, the static electricity on the spinneret panel 102 can be eliminated, avoiding the risk of fire caused by sparks generated by static electricity during laser processing. This is mainly because, during the spinning production process, friction is generated when the wire material spits out from the spinneret hole 103, which is very easy to accumulate static electricity; at the same time, laser processing is a high-energy thermal processing, and electric sparks are easy to generate during the processing. In addition, the dirt in the micropores of the spinneret panel 102 and the spinning workshop are mostly flammable materials. In the process of using laser to clean the spinneret panel 102, it is very easy to cause a fire hazard. This also makes the use of laser to clean the dirt on the spinneret panel 102 truly widely used in actual production.

[0077] Specifically, the laser beam projected from the light outlet 52 acts on the first area on the spinneret panel 102, and the airflow containing positive and negative ions blown out from the air outlet 53 acts on the second area on the spinneret panel 102, and the above-mentioned first area and second area at least partially overlap. In some embodiments, the first area can be completely included in the second area, that is, the area where the laser beam acts on the spinneret panel 102 is swept by the airflow containing positive and negative ions, and the static electricity in the laser action area is eliminated in real time to avoid fire hazards. In the specific setting, there is a spacing greater than 0 between the light outlet 52 and the air outlet 53, wherein the air outlet 53 has a plurality of spaced apart arrangements.

[0078] In this embodiment, the laser cleaning device has a control system, and the specific components of the control system can be integrated in the box in which the laser host 3 is set. The control system is at least used to control the opening and closing of the laser host 3. The laser working head 5 is also provided with a leak detector 55 for detecting the concentration of biphenyl, and the leak detector 55 is connected to the control system in communication. During the laser processing process, if the leak detector 55 detects the presence of biphenyl in the environment, it sends a signal to the control system, and the control system controls the laser host 3 to be turned off and stop emitting the laser beam, thereby avoiding fire.

[0079] In this embodiment, a rangefinder 56 is also provided on the laser working head 5, and the mechanical arm 4 has a motion controller for controlling the motion trajectory of the free end 42 of the mechanical arm 4, and the motion controller is in communication with the rangefinder 56. The distance between the light outlet 52 and the part to be cleaned is measured by the rangefinder 56, and the motion controller controls the movement of the mechanical arm 4 to adjust the distance between the laser working head 5 and the part to be cleaned, so that the laser beam is projected onto the spinneret panel 102 according to the preset parameters to ensure the cleaning effect.

[0080] When the laser plate cleaning machine of this embodiment is used to clean the spinneret plate 102 of the spinning assembly 100, the following steps can be specifically followed:

[0081] The laser working head 5 moves with the free end 42 of the robot 4 to the bottom of the spinneret panel 102, so that the light outlet 52 is upward toward the spinneret panel 102, and the laser beam is projected from the light outlet 52 onto the spinneret panel 102; the robot 4 carries the laser working head 5 to move along the width direction of the spinneret panel 102, and cleans the dirt on the spinneret panel 102 and the spinneret holes 103 thereon in turn along the width direction; the laser cleaning device moves along the length extension direction of the guide rail 22, so that the robot 4 moves along the length direction of the guide rail 22 accordingly, thereby changing the position of the laser working head 5 in the length direction of the spinneret panel 102, and cleaning and processing the spinneret panel 102 in turn along the length direction.

[0082] During actual processing, since the spinning assembly 100 includes multiple spinning boxes 101, when the laser cleaning device moves to a set position along the guide rail 22, the robot arm 4 can move with the laser working head 5 to clean the spinneret panel 102 on the spinning box 101 in both the length and width directions; then, the driving member 60 moves again to make the gear 6 and the rack 23 engage with each other, so that the laser cleaning device moves a certain distance along the guide rail 22, and then the laser working head 5 can clean the spinneret panel 102 on the next spinning box 101 in both the length and width directions.

[0083] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
