Description

TECHNICAL FIELD

[0001] The present application relates to the field of tire cleaning technology, in particular to a tire laser cleaning device. BACKGROUND

[0002] In the field of tire manufacturing, the cleaning of the inner wall of the tire (removing mold release agent, oil stains, dust and other pollutants) is a key process to ensure tire quality and subsequent processing accuracy. However, the existing tire inner wall cleaning technology has many technical problems in the aspects of clamping positioning and dust removal, and the specific problems are as follows: 1. Clamping positioning: poor adaptability and low automation level. The existing clamping structure is mostly a "fixed size clamp", which needs to be replaced for different inner diameters (such as 400-600mm for car tires and 600-1000mm for truck tires). The replacement process takes ≥30 minutes per time, and the storage cost of the clamp is high, which cannot meet the batch cleaning needs of multiple specifications of tires. The clamping process needs to be manually adjusted by workers, which takes ≥5 minutes per time, and improper force control during manual operation may cause the tire to deviate, resulting in local omission or excessive cleaning during laser cleaning; some automatic clamping equipment needs to be additionally equipped with multiple groups of air cylinders / motors, which has a complex structure, high cost (equipment cost increases by more than 40%), and frequent failures (air cylinder leakage, motor overload, etc.).

[0003] 2. Dust removal: low efficiency, serious secondary pollution and inconvenient maintenance.

[0004] The existing dust removal device is mostly a "single suction port" (such as a fixed air suction port at the top of the cleaning chamber), which can only remove part of the oil smoke and dust in the air and cannot cover the recessed areas such as the bottom of the tire inner wall and the bead, and the residual rate of debris (such as rust and rubber particles) in these areas is ≥30%, which needs to be cleaned manually again, seriously affecting the cleaning efficiency. Therefore, we propose a tire laser cleaning device. SUMMARY

[0005] The purpose of the present application is to provide a tire laser cleaning device to solve the problems raised in the background.

After the mobile seat assembly transports the tire to be cleaned directly below the laser cleaning gun assembly, the bottom of the laser cleaning gun assembly extends into the tire and presses against the intermediate abutting assembly, so that the intermediate abutting assembly drives the clamping and positioning assembly to extend into the tire and fix the tire on the middle of the upper end of the mobile seat assembly. When the laser cleaning gun head on the laser cleaning gun assembly cleans the inner wall of the tire, the dust suction assembly cleans the debris inside the tire through the clamping and positioning assembly.

[0007] Preferably, the top of the cleaning chamber is provided with an end cover, and the end cover is provided with an FFU dust remover.

[0008] Preferably, the laser cleaning gun assembly comprises a hydraulic cylinder fixed at the top of the cleaning chamber and a mounting head fixed at the bottom of the piston rod of the hydraulic cylinder, and a plurality of groups of laser cleaning gun heads are fixed on the outer wall of the mounting head.

[0009] Preferably, the mobile seat assembly comprises a mobile seat, an I-shaped roller arranged at the bottom of the mobile seat and controlled by a servo motor, and a cover plate arranged at the top of the mobile seat and used for placing the tire. The I-shaped roller is arranged on the track, and the cover plate is provided with a reserved through hole in the middle thereof and used for extending the clamping and positioning assembly and the intermediate abutting assembly.

[0010] Preferably, the dust suction assembly comprises a dust collector arranged in a mounting groove arranged at the upper end of the mobile seat, a hollow ring connected to the inlet of the dust collector, and a chip removal pipe connected to the outlet of the dust collector, and the hollow ring is arranged outside the plurality of groups of clamping and positioning assemblies.

[0011] Preferably, the inlet of the dust collector is sequentially connected with a dust suction pipe and a connecting pipe, and the connecting pipe is connected to the side edge of the hollow ring. The bottom of the dust suction pipe is in communication with the insertion groove arranged in the bottom of the mobile seat.

[0012] Preferably, the middle of the mounting groove is provided with a containing groove, the upper end of the containing groove is provided with a square frame, the side edges of the square frame are equally spaced to define limiting frames, and the top of each limiting frame is provided with a connecting plate. The clamping and positioning assembly comprises a vertical rack arranged in the limiting frame, hollow clamping arms movably connected between the connecting plates, an arc-shaped pressing pipe in communication with the top of the hollow clamping arms, and arc-shaped tensioning positioning plates connected to the top of the hollow clamping arms. The bottom of the hollow clamping arm is connected to the top of the hollow ring by a hose, and the side edges of the arc-shaped pressing pipe are equally spaced to define negative pressure suction holes.

[0013] Preferably, the rotating shafts on both sides of the hollow clamping arm are movably connected to the corresponding connecting plates, and the hollow clamping arm is further provided with protruding ear plates on both sides of the middle bottom, and the pin shaft at the upper end of the vertical rack is connected to the inclined slot on the protruding ear plate.

[0014] Preferably, the intermediate abutting assembly comprises an abutting column located in the square frame, vertical slots arranged at equal intervals on the lower side of the abutting column, teeth arranged on the inner wall of the vertical slots, and a reset spring fixed at the lower end of the abutting column, wherein the bottom of the reset spring is connected to the accommodating groove.

[0015] Preferably, a gear wheel is movably connected in the limiting frame, the inner side of the gear wheel extends into the vertical slot, and the gear wheel is engaged between the teeth and the corresponding vertical rack.

[0016] Compared with the prior art, the present application has the following advantages: through the mechanical linkage of the "intermediate abutting assembly + clamping positioning assembly", the present application realizes self-adaptive adjustment of the clamping range, adapts to mainstream specifications of tires such as car tires, truck tires and engineering tires, does not need to replace any tooling, improves the clamping and adapting efficiency, and completely solves the problem of "time-consuming replacement of tooling" of traditional equipment. The clamping process is triggered by the lifting action of the laser cleaning gun assembly, without the need for additional cylinders / motors. Through the pure mechanical linkage of "abutting column pressing down-gear and rack transmission-clamping arm opening", the whole process automation of "tire positioning-automatic clamping-cleaning completion-automatic clamping release" is realized. The time consumption of single clamping is shortened from 5 minutes in the traditional way to 1 minute. Accurate center positioning and avoidance of deviation: the arc-shaped tensioning positioning plate is attached to the inner wall of the tire bead, which can automatically center and limit the tire. In addition, multiple hollow clamping arms are distributed at equal intervals along the circumference (usually 3-4 groups), and the clamping force is uniformly transmitted to the inner wall of the tire, further realizing the fixation of the tire.

[0017] The dust collection assembly is deeply integrated with the clamping positioning assembly. The arc-shaped compression tube is attached to the inner wall of the tire bottom along with the clamping arm, which can directly approach the debris residue area, covering the recessed areas such as the inner wall bottom and the bead of the tire. The negative pressure generated by the dust collector is transmitted to the negative pressure suction hole through the hollow ring and the hose, realizing "cleaning and dust collection simultaneously", reducing the debris residue rate, and eliminating the need for manual secondary cleaning.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0021] Embodiment: Please refer to Figures 1-16 The present application provides a technical solution: The tire laser cleaning device comprises a control console 6 and a cleaning chamber 1. The cleaning chamber 1 is provided with an end cover 4 at the top, and the end cover 4 is provided with an FFU dust remover 5.

[0022] The lower front side of the cleaning chamber 1 is further provided with an electric moving opening and closing door 7. After the electric moving opening and closing door 7 is opened, it is convenient to check and maintain the equipment inside the cleaning chamber 1.

[0023] The control console 6 comprises a touch display screen and a PLC controller built in the touch display screen. The PLC controller controls the work of the FFU dust remover 5. The fan of the FFU dust remover 5 works, sucks the air in the cleaning chamber 1 upwards, filters it through the filter element of the FFU dust remover 5, and then discharges it out of the cleaning chamber 1, thereby ensuring that the air in the working room where the tire laser cleaning device is installed is in a clean state.

[0024] The FFU dust remover 5 is designed by "updraft" air flow, which filters and cleans the air in the cleaning chamber 1 in real time, prevents the oil fume and dust generated by laser cleaning from spreading to the workshop, and avoids external dust from entering the cleaning chamber 1 to pollute the tire 8.

[0025] The top of the cleaning chamber 1 is provided with a laser cleaning gun assembly; The laser cleaning gun assembly comprises a hydraulic cylinder 11 fixed at the top of the cleaning chamber 1 and a mounting head 3 fixed at the bottom of a piston rod 12 of the hydraulic cylinder 11, and a plurality of groups of laser cleaning gun heads 13 are fixed on the outer wall of the mounting head 3.

[0026] The PLC controller controls the extension or retraction of the piston rod 12 by controlling the working of the hydraulic oil pump to realize the communication between the hydraulic oil and the hydraulic cylinder 11. Since the plurality of groups of laser cleaning gun heads 13 are fixed on the outer wall of the mounting head 3, when the PLC controller controls the working of the laser generator in the laser cleaning gun head 13, the laser beam emitted by the laser generator can cover the inner wall of the tire 8 and clean the inner wall of the tire 8.

[0027] By using the photo-thermal effect, photo-stripping effect or photo-shock wave effect of high-energy laser beam, the contaminants such as release agent, oil stain, dust and aging layer attached to the inner wall can be removed without damaging the tire base material (rubber, cord, etc.).

[0028] The hydraulic cylinder 11 is driven by hydraulic pressure, and compared with an electric push rod, the hydraulic cylinder 11 has larger thrust and runs more smoothly. The circumferential distribution design of the laser cleaning gun head 13 can cover the circumferential area of the inner wall of the tire 8 at one time, and the laser cleaning gun head 13 does not need to be additionally rotated, so that the cleaning efficiency is improved; and in cooperation with the up-down movement of the piston rod 12, the laser cleaning gun head 13 can cover the full height of the inner wall of the tire 8, so that the problem of "partial omission" in the traditional handheld cleaning is solved.

[0029] The moving seat assembly 9 for placing the tire 8 is arranged on the track 10 at the bottom of the cleaning chamber 1. The track 10 extends out from the openings at both ends of the bottom of the cleaning chamber 1, and dust-proof curtain fabrics 2 are arranged at the openings at both ends of the bottom of the cleaning chamber 1. The dust-proof curtain fabrics 2 do not hinder the passing of the moving seat assembly 9 and the tire 8 at the top of the moving seat assembly 9, and can prevent external dust from entering the cleaning chamber 1 to ensure the cleanliness in the chamber.

[0030] The laser cleaning gun assembly and the moving seat assembly 9 are controlled by the control console 6. The moving seat assembly 9 comprises a moving seat 901, an I-shaped roller 903 arranged at the bottom of the moving seat 901 and controlled by a servo motor, and a cover plate 902 arranged at the top of the moving seat 901 and used for placing the tire 8. The I-shaped roller 903 is arranged on the track 10, and under the control of the PLC controller on the servo motor, the servo motor drives the I-shaped roller 903 to roll, so that the moving seat assembly 9 can transport the tire 8 along the track 10.

[0031] The I-shaped roller 903 is driven by the servo motor, and cooperates with the guiding action of the track 10, the conveying precision reaches ±0.5mm, and it is ensured that the tire 8 can be accurately positioned below the laser cleaning gun assembly, so as to avoid cleaning deviation.

[0032] The track 10 adopts a high-precision linear guide rail (positioning precision ±0.5mm), and a preset “position detection sensor” (such as a photoelectric sensor, not marked, which is a conventional supporting design) is arranged in the cleaning chamber 1. When the sensor detects that the tire 8 reaches below the laser cleaning gun assembly, a feedback signal is immediately fed back to the PLC, the PLC controls the servo motor to stop, and the tire completes “rough positioning”, so as to ensure that the laser cleaning gun head 13 can accurately extend into the tire.

[0033] The laser cleaning gun assembly directly triggers the mechanical linkage of the intermediate abutting assembly 907 and the clamping positioning assembly 906 through its own descending action (driven by the hydraulic cylinder 11), so as to realize “fine positioning” of the tire 8.

[0034] The middle part of the cover plate 902 is provided with a reserved through hole 908 for extending the top of the clamping positioning assembly 906 and the intermediate abutting assembly 907.

[0035] The reserved through hole 908 can be adapted to tires 8 of different diameters (only the inner diameter of the tire 8 needs to be larger than the diameter of the reserved through hole 908), without the need to replace the tooling, and the versatility of the device is improved.

[0036] The dust collection assembly includes a dust collector 909 mounted in a mounting groove 918 at the upper end of the moving seat 901, a hollow ring 913 connected at the inlet of the dust collector 909, and a chip removal pipe 910 connected at the outlet of the dust collector 909 (the dust collector 909 is controlled by a PLC controller), and the hollow ring 913 is arranged outside the clamping positioning assembly 906.

[0037] The dust collector 909 is sequentially connected with a dust collection pipe 911 and a connecting pipe 912, and the connecting pipe 912 is connected to the side of the hollow ring 913. The bottom of the moving seat 901 is provided with a plug-in groove 905 for inserting the drawer 904, and the bottom of the chip removal pipe 910 is in communication with the plug-in groove 905.

[0038] The middle part of the mounting groove 918 is provided with a containing groove 917, the upper end of the containing groove 917 is provided with a square frame 914, the side edges of the square frame 914 are equally spaced to limit the frame 919, and the top of the limiting frame 919 is provided with a connecting plate 916 on both sides. The clamping positioning assembly 906 includes a vertical rack 90603 arranged in the limiting frame 919, hollow clamping arms 90601 movably connected between the connecting plates 916, an arc-shaped pressing tube 90610 communicated with the top of the hollow clamping arms 90601, and arc-shaped tensioning positioning plates 90608 connected to the outside of the top of the hollow clamping arms 90601. The bottom of the hollow clamping arms 90601 is connected to the top of the hollow ring 913 by a hose 90602, and negative pressure suction holes 90609 are arranged at equal intervals on the side edges of the arc-shaped pressing tube 90610.

[0039] The rotating shafts 90606 on the two sides of the hollow clamping arms 90601 are movably connected to the corresponding connecting plates 916, and the middle bottom of the hollow clamping arms 90601 is further provided with protruding ear plates 90604, and the pin shaft 90605 at the upper end of the vertical rack 90603 is connected to the inclined slot 90607 on the protruding ear plate 90604.

[0040] The intermediate abutting assembly 907 includes an abutting column 9071 located in the square frame 914, vertical slots 9072 arranged at equal intervals on the lower side edges of the abutting column 9071, teeth 9073 arranged on the inner walls of the vertical slots 9072, and a reset spring 9074 fixed at the lower end of the abutting column 9071, and the bottom of the reset spring 9074 is connected to the accommodating groove 917.

[0041] The limiting frame 919 is further movably connected with a gear 915, the inner side of the gear 915 extends into the vertical slot 9072, and the gear 915 is engaged between the teeth 9073 and the corresponding vertical rack 90603. The "mechanical linkage" design does not require an additional power source (only relies on the downward action of the laser cleaning gun assembly to drive), simplifies the structure, and reduces energy consumption; When the abutting column 9071 is pressed down, the gear 915 and the vertical rack 90603 drive multiple sets of hollow clamping arms 90601 to open synchronously, realizing uniform force fixation of the tire 8 and avoiding damage to the inner wall of the tire 8 due to excessive local pressure; The arc-shaped tensioning positioning plates 90608 are designed to fit the arc-shaped inner wall of the tire 8, have strong fixation stability, and realize the center limiting of the tire 8; The arc-shaped pressing pipe 90610 is attached to the inner wall of the bottom of the tire 8 along with the hollow clamping arm 90601, so as to realize clamping and fixing of the tire 8, and to prepare for subsequent dust suction. When the laser cleaning gun head 13 cleans the inner wall of the tire 8, the debris or dust falling off the inner wall of the tire 8 will fall onto the inner wall of the bottom of the tire 8. Under the action of the negative pressure suction force generated by the arc-shaped pressing pipe 90610 of the dust suction assembly, the range of the negative pressure suction force generated when the arc-shaped pressing pipe 90610 is attached to the inner wall of the bottom of the tire 8 can cover the inner wall of the bottom of the tire 8 through the arc-shaped pressing pipe 90610. Thus, when the dust suction assembly is working, the debris or dust on the inner wall of the bottom of the tire 8 can be completely cleaned and collected through the arc-shaped pressing pipe 90610.

[0042] The reset spring 9074 can automatically drive the assembly to shrink and reset, without manual operation, thereby improving the degree of automation.

[0043] The mobile seat assembly 9 is provided with a plurality of clamping positioning assemblies 906, an intermediate abutting assembly 907 located in the middle of the clamping positioning assemblies 906, and a dust suction assembly in communication with the clamping positioning assemblies 906. After the mobile seat assembly 9 transports the tire 8 to the position directly below the laser cleaning gun assembly, the bottom of the laser cleaning gun assembly is inserted into the tire 8 and pressed against the intermediate abutting assembly 907, so that the intermediate abutting assembly 907 drives the clamping positioning assembly 906 to expand and then extends into the tire 8, thereby limiting and fixing the tire 8 on the middle of the upper end of the mobile seat assembly 9. When the laser cleaning gun head 13 on the laser cleaning gun assembly cleans the inner wall of the tire 8, the dust suction assembly cleans the debris inside the tire 8 through the clamping positioning assembly 906.

[0044] The dust suction path of the dust suction assembly is combined with the clamping positioning assembly 906, and the negative pressure suction hole 90609 is attached to the inner wall of the bottom of the tire 8 along with the hollow clamping arm 90601, so as to directly suck away the debris and oil fume generated by the laser cleaning, with a dust suction efficiency of more than 95%, thereby avoiding secondary attachment of pollutants. The drawer 904 can collect larger debris, which can be cleaned regularly, thereby being convenient to maintain. The dust collector 909 is integrated on the mobile seat 901 and moves synchronously with the mobile seat, without the need for additional long-distance dust suction pipeline, thereby simplifying the layout of the device.

[0045] Specifically, in use, the tire laser cleaning device coordinates the laser cleaning gun assembly, the mobile seat assembly 9, the dust suction assembly and the FFU dust collector 5 in the cleaning chamber 1 through the console 6 (containing a PLC controller), so as to realize automatic and dust-free cleaning of the inner wall of the tire 8. The core working process includes five stages of “tire conveying-positioning and fixing-laser cleaning-dust removal and debris removal-cleaning completion”, which are as follows: 1. Preparation stage: equipment start-up and parameter presetting.

[0046] The operator inputs cleaning parameters (such as laser power, cleaning time) through the touch display screen of the console 6, and the PLC controller synchronously starts the FFU dust remover 5: the fan of the FFU dust remover 5 works to suck the air in the cleaning chamber 1 upwards, and the air is filtered by the internal filter element before being discharged, thus creating a clean cleaning environment in advance to avoid external dust interfering with the cleaning process. At the same time, the PLC controller initializes the laser cleaning gun assembly (the piston rod 12 of the hydraulic cylinder 11 retracts, driving the mounting head 3 and the laser cleaning gun head 13 to rise to the initial position) and the moving seat assembly 9 (the I-shaped roller 903 is at the starting end of the track 10, and the clamping positioning assembly 906 is in the retracted state).

[0047] 2. Tire conveying stage: moving seat assembly 9 feeding.

[0048] Place the tire 8 to be cleaned on the cover plate 902 of the moving seat assembly 9, and the operator sends a "conveying instruction" through the console 6. The PLC controller controls the servo motor of the moving seat assembly 9 to start, driving the I-shaped roller 903 to roll along the track 10 and move the tire 8 to the inside of the cleaning chamber 1. When the tire 8 reaches directly below the laser cleaning gun assembly, the servo motor stops, and the moving seat assembly 9 is accurately positioned.

[0049] 3. Tire 8 positioning and fixing stage: clamping positioning assembly linkage locking.

[0050] The PLC controller sends an instruction to the hydraulic oil pump to control the hydraulic oil to enter the hydraulic cylinder 11, pushing the piston rod 12 to extend downward, driving the mounting head 3 and the circumferentially fixed laser cleaning gun head 13 to move downward synchronously until the laser cleaning gun head 13 extends into the inside of the tire 8, and at the same time, the bottom of the mounting head 3 presses the abutting column 9071 of the intermediate abutting assembly 907.

[0051] Intermediate abutting assembly 907 action: the abutting column 9071 is compressed by pressure to compress the reset spring 9074 downward, and the teeth 9073 in the vertical slot 9072 at the lower part of the abutting column 9071 move downward synchronously, driving the meshed gear 915 (located in the limiting frame 919) to rotate; Clamping positioning assembly 906 linkage opening: when the gear 915 rotates, it synchronously drives the meshed vertical rack 90603 to move upward, the pin shaft 90605 at the upper end of the vertical rack 90603 slides along the inclined slot 90607 of the protruding lug plate 90604, pushing the hollow clamping arm 90601 to open outward around the rotating shaft 90606, until the arc-shaped tensioning positioning plate 90608 adheres to the inner wall of the tire 8 bead, achieving radial positioning and fixing of the tire 8; at the same time, the arc-shaped pressing pipe 90610 adheres to the inner wall of the bottom of the tire 8 with the hollow clamping arm 90601, achieving clamping and fixing of the tire 8, preparing for subsequent dust suction.

[0052] 4. Laser cleaning and dust removal and debris removal stage: synchronous cleaning.

[0053] Laser cleaning: the PLC controller starts the laser generator in the laser cleaning gun head 13, and several groups of laser cleaning gun heads 13 (fixed on the outer wall of the mounting head 3) simultaneously emit laser beams, using the photo-thermal effect, photo-stripping effect or photo-shock wave effect to cover and remove the mold release agent, oil stains, dust and other pollutants on the inner wall of the tire 8.

[0054] Dust removal: the PLC controller synchronously starts the dust collector 909 of the dust removal assembly, and the dust collector 909 generates negative pressure, which is transmitted to the hollow ring 913 through the chip removal pipe 910, the dust removal pipe 911, the connecting pipe 912, and then introduced into the hollow clamping arm 90601 through the hose 90602, and finally through the negative pressure suction hole 90609 on the side edge of the arc-shaped compression pipe 90610, the debris and oil fumes generated by laser cleaning are directly sucked into the dust collector 909, avoiding the attachment of pollutants on the inner wall of the tire 8 or the diffusion to the cleaning chamber 1; part of the larger debris falls into the drawer 904 (inserted into the slot 905) at the bottom of the moving seat 901 through the chip removal pipe 910, facilitating subsequent centralized cleaning.

[0055] 5. Cleaning completion stage: reset and unloading.

[0056] After the cleaning parameters reach the preset value, the PLC controller sequentially closes the laser cleaning gun head 13 and the dust collector 909, controls the hydraulic oil pump to supply oil in the reverse direction, so that the piston rod 12 of the hydraulic cylinder 11 retracts, drives the mounting head 3 and the laser cleaning gun head 13 to rise and separate from the tire 8; at the same time, the reset spring 9074 of the middle abutting assembly 907 rebounds, pushes the abutting column 9071 to rise, the gear 915 is driven by the gear teeth 9073 to rotate in the reverse direction, the vertical rack 90603 moves downward, and the hollow clamping arm 90601 is retracted and reset, releasing the fixation of the tire 8. Finally, the PLC controller controls the servo motor of the moving seat assembly 9 to drive the I-shaped roller 903 along the track 10 to send the cleaned tire 8 out of the cleaning chamber 1, completing a cleaning cycle.

[0057] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
