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:

[0003] 1. Clamping positioning: poor adaptability and low automation level.

[0004] 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.

[0005] The clamping process needs to be manually adjusted by workers, which takes ≥5 minutes per time, and improper force control during manual operation can 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 cylinder / motor drives, which has a complex structure, high cost (equipment cost increases by more than 40%), and frequent failures (cylinder leakage, motor overload, etc.).

[0006] 2. Dust removal: low efficiency, serious secondary pollution and inconvenient maintenance.

[0007] 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. 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.

DETAILED DESCRIPTION

[0048] 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 those skilled in the art without creative labor fall within the scope of protection of the present application.

[0049] Embodiment:

[0050] Please refer to Figures 1-16 The present application provides a technical solution:

[0051] A 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.

[0052] 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.

[0053] 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 to suck the air in the cleaning chamber 1 upward, and then the air is filtered by the filter element of the FFU dust remover 5 and discharged from 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.

[0054] FFU dust collector 5 is designed by "updraft" air flow, real-time filtering and cleaning the air in the chamber 1, to prevent the oil smoke, dust generated by laser cleaning spread to the workshop, while avoiding external dust into the cleaning chamber 1 pollution tire 8.

[0055] The top of the cleaning chamber 1 is provided with a laser cleaning gun assembly;

[0056] The laser cleaning gun assembly includes a hydraulic cylinder 11 fixed at the top of the cleaning chamber 1 and a mounting head 3 fixed at the bottom of the piston rod 12 output end 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.

[0057] The PLC controller controls the hydraulic oil pump to realize the communication between the hydraulic oil and the hydraulic cylinder 11, so as to control the extension or retraction of the piston rod 12;

[0058] 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 laser generator in the laser cleaning gun head 13 to work, 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.

[0059] 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.).

[0060] The hydraulic cylinder 11 is driven by hydraulic pressure, and compared with the electric push rod, the thrust is larger and the operation is more stable;

[0061] The laser cleaning gun head 13 is designed to be distributed in the circumferential direction, which can cover the circumferential area of the inner wall of the tire 8 at one time without additional rotation of the laser cleaning gun head 13, and the cleaning efficiency is improved; in combination with the up-down movement of the piston rod 12, the full height of the inner wall of the tire 8 can be covered, and the problem of "partial omission" in traditional handheld cleaning is solved.

[0062] The moving seat assembly 9 for placing the tire 8 is arranged on the track 10 at the bottom of the cleaning chamber 1;

[0063] The track 10 extends from the openings at both ends of the bottom of the cleaning chamber 1, and dust-proof curtain 2 is arranged at the openings at both ends of the bottom of the cleaning chamber 1. The dust-proof curtain 2 does not hinder the passage of the moving seat assembly 9 and the tire 8 at the upper end of the moving seat assembly 9, and can prevent external dust from entering the cleaning chamber 1, thereby ensuring the cleanliness in the chamber.

[0064] The laser cleaning gun assembly and the moving seat assembly 9 are controlled by the console 6;

[0065] The movable seat assembly 9 includes a movable seat 901, an I-shaped roller 903 controlled by a servo motor at the bottom of the movable seat 901, and a cover plate 902 installed on the top of the movable seat 901 for placing the tire 8.

[0066] The I-shaped roller 903 sits on the track 10. Under the control of the servo motor by the PLC controller, 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.

[0067] The I-shaped roller 903 is driven by a servo motor and, together with the guiding effect of the track 10, achieves a conveying accuracy of ±0.5mm, ensuring that the tire 8 can be accurately positioned directly below the laser cleaning gun assembly to avoid cleaning deviation.

[0068] The track 10 adopts a high-precision linear guide rail (positioning accuracy ±0.5mm), and the cleaning chamber 1 is equipped with a "position detection sensor" (such as a photoelectric sensor, which is not clearly marked and is a standard accessory design). When the sensor detects that the tire 8 has reached the bottom of the laser cleaning gun assembly, it immediately sends a signal to the PLC. The PLC controls the servo motor to stop, and the tire completes "coarse positioning" to ensure that the laser cleaning gun head 13 can accurately extend into the tire.

[0069] The laser cleaning gun assembly directly triggers the mechanical linkage between the intermediate abutment assembly 907 and the clamping and positioning assembly 906 through its own descent action (driven by hydraulic cylinder 11), thereby achieving "precise fixing" of the tire 8.

[0070] The cover plate 902 has a reserved through hole 908 in the middle for extending the clamping and positioning component 906 and the top of the intermediate abutment component 907.

[0071] The reserved through hole 908 can be adapted to tires 8 of different diameters (as long as the inner diameter of the tire 8 is larger than the diameter of the reserved through hole 908), without the need to change tooling, thus improving the versatility of the device.

[0072] The dust collection assembly includes a vacuum cleaner 909 installed in a mounting slot 918 on the upper end of the movable seat 901, a hollow ring 913 connected to the inlet of the vacuum cleaner 909, and a chip removal pipe 910 connected to the outlet of the vacuum cleaner 909 (the vacuum cleaner 909 is controlled by a PLC controller). The hollow ring 913 is located on the outside of a plurality of assembly clamping positioning components 906.

[0073] The vacuum cleaner 909 has a suction pipe 911 and a connecting pipe 912 connected sequentially at the inlet, and the connecting pipe 912 is connected to the side of the hollow ring 913.

[0074] The bottom of the movable seat 901 is provided with a slot 905 for inserting the drawer 904, and the bottom of the chip removal pipe 910 is connected to the slot 905.

[0075] The middle part of the mounting groove 918 is provided with a receiving groove 917, the upper end of the receiving groove 917 is provided with a square frame 914, the side edges of the square frame 914 are equidistantly provided with limiting frames 919, and the two sides of the top of each limiting frame 919 is provided with a connecting plate 916;

[0076] The clamping and positioning assembly 906 includes a vertical rack 90603 arranged in the limiting frame 919, a hollow clamping arm 90601 movably connected between the connecting plates 916, an arc-shaped pressing tube 90610 communicated with the top of the hollow clamping arm 90601, and an arc-shaped tensioning positioning plate 90608 connected to the top outside of the hollow clamping arm 90601;

[0077] The bottom of the hollow clamping arm 90601 is connected to the top of the hollow ring 913 through a hose 90602, and negative pressure suction holes 90609 are equidistantly arranged on the side edges of the arc-shaped pressing tube 90610.

[0078] The rotating shafts 90606 on the two sides of the hollow clamping arm 90601 are movably connected to the corresponding connecting plates 916, and the middle bottom of the hollow clamping arm 90601 is further provided with a protruding ear plate 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.

[0079] The middle abutting assembly 907 includes an abutting column 9071 located in the square frame 914, vertical slots 9072 equidistantly arranged 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 receiving groove 917.

[0080] 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 driving action of the laser cleaning gun assembly), simplifies the structure and reduces energy consumption;

[0081] When the abutting column 9071 is pressed down, the gear 915 and the vertical rack 90603 drive multiple groups of hollow clamping arms 90601 to open synchronously, so that the tire 8 is uniformly stressed and fixed, and local excessive pressure is avoided to damage the inner wall of the tire 8;

[0082] The arc-shaped tensioning positioning plate 90608 is designed to be arc-shaped and fit the inner wall of the tire 8, has high fixing stability, and can centrally limit the tire 8;

[0083] 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. In this way, 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.

[0084] The reset spring 9074 can automatically drive the assembly to shrink and reset, without manual operation, thereby improving the degree of automation.

[0085] 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 plurality of clamping positioning assemblies 906, and a dust suction assembly in communication with the clamping positioning assembly 906.

[0086] 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 extends into the tire 8 and presses against the intermediate abutting assembly 907, so that the intermediate abutting assembly 907 drives the clamping positioning assembly 906 to open and extend into the tire 8, thereby limiting and fixing the tire 8 on the middle of the upper end of the mobile seat assembly 9.

[0087] When the laser cleaning gun head 13 of the laser cleaning gun assembly cleans the inner wall of the tire 8, the dust suction assembly cleans the debris in the tire 8 through the clamping positioning assembly 906.

[0088] 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.

[0089] 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 to additionally arrange a long-distance dust suction pipeline, thereby simplifying the layout of the device.

[0090] 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 transportation-positioning and fixing-laser cleaning-dust and debris removal-cleaning completion”, which are as follows:

[0091] 1. Preparation stage: device startup and parameter presetting.

[0092] The operator inputs the 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, and the air in the cleaning chamber 1 is sucked upward, filtered by the internal filter element, and then discharged, thus creating a clean cleaning environment in advance and avoiding external dust interference 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).

[0093] 2. Tire conveying stage: moving seat assembly 9 feeding.

[0094] 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, drives the I-shaped roller 903 to roll along the track 10, and drives the tire 8 to move towards 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.

[0095] 3. Tire 8 positioning and fixing stage: clamping positioning assembly linkage locking.

[0096] The PLC controller sends an instruction to the hydraulic oil pump to control the hydraulic oil to enter the hydraulic cylinder 11, push the piston rod 12 to extend downward, drive 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 mounting head 3 bottom presses the abutting column 9071 of the intermediate abutting assembly 907.

[0097] Intermediate abutting assembly 907 action: abutting column 9071 is compressed under pressure to compress reset spring 9074, and the teeth 9073 in the vertical slot 9072 at the lower part of the side edge move downward synchronously, driving the meshed gear 915 (located in the limiting frame 919) to rotate;

[0098] Clamping and positioning assembly 906 linkage opening: when gear 915 rotates, the meshed vertical rack 90603 is synchronously driven to move upward, the pin shaft 90605 at the upper end of the vertical rack 90603 slides along the inclined groove 90607 of the convex ear plate 90604, pushing the top of the hollow clamping arm 90601 to expand 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 limiting 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 along with the hollow clamping arm 90601, achieving clamping and fixing of the tire 8, preparing for subsequent dust suction.

[0099] 4. Laser cleaning and dust removal stage: synchronous cleaning.

[0100] Laser cleaning: the PLC controller starts the laser generator in the laser cleaning gun head 13, and a plurality of groups of laser cleaning gun heads 13 (fixed on the outer wall of the mounting head 3) synchronously emit laser beams, using the photo-thermal effect, photo-stripping effect or photo-shock wave effect to cover and remove contaminants such as release agent, oil stains and dust on the inner wall of the tire 8.

[0101] 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 suction pipe 911 and the connecting pipe 912, and then introduced into the hollow clamping arm 90601 through the hose 90602, and finally through the negative pressure suction holes 90609 on the side edges of the arc-shaped pressing 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 concentrated cleaning.

[0102] 5. Cleaning completion stage: reset and unloading.

[0103] 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 reverse, and makes the piston rod 12 of the hydraulic cylinder 11 retract, driving 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, pushing the abutting column 9071 to rise, the gear teeth 9073 drive the gear 915 to rotate in reverse, the vertical rack 90603 moves downward, and the hollow clamping arm 90601 retracts and resets, releasing the fixing 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.

[0104] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
