Description

Technical Field

[0001] The present invention relates to the field of automotive parts maintenance, and particularly to a device for removing rust from the surface of automotive parts. Background Art

[0002] Automotive parts maintenance is to perform maintenance and repair on various parts of an automobile to ensure its performance and safety. During the operation of an automobile, various parts are constantly worn and aged, prone to failures, which affect the power and fuel consumption of the automobile. For the disassembled parts, rust removal is an important maintenance step. Rust not only weakens the strength of the parts, but may also cause changes in the fit clearance and poor operation. Through rust removal treatment, the surface state of the parts can be restored, their service life can be extended, the stable operation of each system of the automobile can be ensured, and the automobile can always be in a good working state.

[0003] Currently, laser pulse rust removal machines are generally used for rust removal in factories. The working principle of a laser pulse rust removal machine is to use a laser pulse with a high energy density to irradiate the rusty part. When the laser beam interacts with the rust layer on the metal surface, the rust layer will instantaneously absorb a large amount of laser energy, and the temperature will rise sharply. Due to the different thermal expansion coefficients of the rust layer and the metal substrate, the rust layer will quickly vaporize, evaporate, or peel off from the metal surface due to the action of thermal stress.

[0004] The laser pulse rust removal machine has a large scanning area, which is more convenient for cleaning large parts. Because most of the laser can scan the surface of large parts, it can efficiently remove the rust layer and reduce the time and difficulty of manual operation. However, it is more difficult to operate when removing rust from small parts. On the one hand, small parts are small in size and limited in thickness. When removing rust, repeated scanning is required. The laser energy is concentrated in a relatively small area, and the heat is difficult to dissipate quickly. If the laser energy density is not properly controlled, it is easy to cause local overheating during manual cleaning, which may lead to deformation of the parts. On the other hand, there is a fixed energy consumption during the startup and operation of the equipment. The large-area scanning of the laser pulse rust removal machine will cause many laser beams to be unable to effectively act on the rust layer of small parts, resulting in a higher energy consumption per unit area when processing small parts, thus causing energy waste. Summary of the Invention

Specific implementation manner

[0027] The specific implementation manner of the present invention will be described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific implementation manner.

[0028] As Figures 1 to 6 shown, a surface rust removal device for automobile parts provided by an embodiment of the present invention includes an installation box frame 1, a laser rust removal component 3 is arranged on the installation box frame 1, and an arc-shaped moving mechanism 4 capable of driving the laser rust removal component 3 to move along an arc path. In addition, a conveying component for supporting the parts and realizing passive transportation is also equipped inside the installation box frame 1, and a reciprocating driving mechanism 5 that drives the conveying component to perform a two-way alternating reciprocating motion, and the forward displacement is greater than the reverse displacement.

[0029] During the actual operation process, the staff only needs to evenly and closely place multiple groups of parts on the conveying component. The conveying component starts to work and drives the parts to perform a two-way alternating reciprocating motion. This reciprocating motion enables the parts to be reciprocally scanned by the laser rust removal component 3, thereby ensuring that the surface of the components can be evenly and efficiently rust-removed. In this way, the situation of deformation caused by excessive local temperature can be effectively reduced. At the same time, the arc-shaped moving mechanism 4 will drive the laser rust removal component 3 to perform an arc-shaped surrounding motion above the parts, realizing multi-angle scanning and cleaning, making the rust removal and cleaning work more thorough, and greatly improving the rust removal quality.

[0030] In a specific embodiment, the arc-shaped moving mechanism 4 includes fixed frames 401 fixedly arranged on both sides of the installation box frame 1. Arc-shaped support frames 402 are fixedly arranged on the front and rear sides of the fixed frames 401. Rotating shafts 404 are rotatably arranged at the lower ends of both sides of each group of arc-shaped support frames 402. A first transmission belt 406 is wound around the side surface of each group of rotating shafts 404. Grooves are circumferentially formed on the rotating shafts 404 to cooperate with the first transmission belt 406, so as to ensure that the first transmission belt 406 can be stably wound on the rotating shafts 404. An arc-shaped guide rail 403 is further arranged on the arc-shaped support frame 402. A groove is formed on the arc-shaped guide rail 403, and a lubricating layer is covered inside the groove. The lubricating layer is preferably a polytetrafluoroethylene coating, which has good lubricating performance and can reduce the friction force of the laser rust removal component 3 during movement, improving the smoothness of movement. The laser rust removal component 3 is slidably matched with the arc-shaped guide rail 403. The bottom of each group of first transmission belts 406 is slidably matched with the corresponding side of the arc-shaped guide rail 403, and the free end of each group of first transmission belts 406 is fixedly connected to the corresponding side of the laser rust removal component 3. A power component is arranged on the fixed frame 401 for driving the rotating shaft 404 to rotate.

[0031] Among them, the power component may be composed of a first servo motor 405 fixedly arranged on the fixed frame 401. The output end of the first servo motor 405 is coaxially and fixedly connected to a group of rotating shafts 404. A second transmission belt 407 is arranged in cooperation with the two groups of rotating shafts 404. Grooves are circumferentially formed on each group of rotating shafts 404 to cooperate with the second transmission belt 407.

[0032] During use, the first servo motor 405 starts to work, driving the corresponding rotating shaft 404 to rotate. The rotating shaft 404 drives the other group of rotating shafts 404 to rotate through the second transmission belt 407, so that the two groups of rotating shafts 404 rotate in the same direction. At this time, one group of rotating shafts 404 will tighten the transmission belt on the side, and the other group of rotating shafts 404 will release the transmission belt on the side, thereby driving the laser rust removal component 3 to move along the arc-shaped guide rail 403. The first servo motor 405 rotates periodically back and forth, thereby driving the laser rust removal component 3 to move back and forth along the arc-shaped guide rail 403, achieving the effect of the laser rust removal component 3 moving along an arc path. Here, the laser rust removal component 3 may be a mounting frame slidably matched with the arc-shaped guide rail 403, and the output end of a laser pulse rust remover detachably connected to the mounting frame. This detachable design facilitates the maintenance and replacement of the output end of the laser pulse rust remover.

[0033] In another specific embodiment, the conveying assembly includes rotating cylinders 101 rotatably arranged at both ends inside the mounting box frame 1, and a conveyor belt 103 cooperatively arranged on the two groups of rotating cylinders 101. The rotating cylinders 101 play a role in supporting the conveyor belt 103, and the conveyor belt 103 is responsible for passively transporting the accessories. The surface of the conveyor belt 103 is covered with a protective layer to prevent the laser from damaging the conveyor belt 103. A light end sensor can be arranged on one side of the mounting box frame 1. The light end sensor can sense the position of the accessories in real time. When the accessories reach the specified position, the laser rust removal assembly 3 is stopped and started in a timely manner to avoid unnecessary energy waste.

[0034] Among them, there are various choices for the protective layer. One is multiple groups of aluminum sheets covering the surface of the conveyor belt. All the aluminum sheets are arranged in a laminated manner, and the edges of each aluminum sheet overlap each other to form a continuous shielding effect. The aluminum sheets can effectively protect the conveyor belt 103 from the influence of the laser. Another option is sheet-shaped hard materials covering the surface of the conveyor belt. Each group of sheet-shaped hard materials is coated with a ceramic composite coating on the surface. The ceramic composite coating can not only improve the friction force to ensure the stability of the loaded accessories, but also avoid the influence of the laser on the surface of the conveyor belt 103. All the sheet-shaped hard materials are also arranged in a laminated manner, and the edges of each sheet-shaped hard material overlap each other to form a continuous shielding effect.

[0035] In a specific embodiment, the reciprocating drive mechanism 5 includes a guide plate 507 fixedly arranged inside the mounting box frame 1, and a transmission toothed belt 505 arranged inside the conveyor belt 103. A slider 508 is slidably fitted on the guide plate 507, and two groups of limit holes 510 are longitudinally penetrated through the slider 508. A first limiting body 511 is arranged inside one group of limit holes 510, and a second limiting body 512 is arranged inside the other group of limit holes 510. The upper end cross-sections of the first limiting body 511 and the second limiting body 512 are both in a polygonal columnar structure, ensuring that the relevant components can slide stably along the limit holes 510. The second limiting body 512 includes a fixing body 5121 fixedly connected to the inside of the limit hole 510. A spring 5122 is fixedly arranged at the upper end of the fixing body 5121, and an upper limit post 5123 is fixedly arranged at the upper end of the spring 5122. A slope is arranged on the front side of the upper end of the upper limit post 5123. The first limiting body 511 is slidably fitted with the corresponding limit hole 510. A slope is arranged on the front side of the top of the first limiting body 511, and a roller 5111 is rotatably arranged at the bottom of the first limiting body 511. A groove 506 extending along the direction of the guide plate 507 is formed in the middle of the guide plate 507. The slider 508 does not contact the bottom of the groove 506. A lifting plate 509 cooperating with the roller 5111 is fixedly arranged at the rear side inside the groove 506. A slope is arranged at the front end of the lifting plate 509, and the lifting plate 509 does not extend to the front side of the groove 506. Multiple groups of tooth grooves are equidistantly arranged on the transmission toothed belt 505, and the tooth grooves on the transmission toothed belt 505 cooperate with the slopes at the upper ends of the first limiting body 511 and the second limiting body 512. A pushing component for driving the slider 508 to reciprocate horizontally is arranged inside the mounting box frame 1.

[0036] When the slider 508 reciprocates horizontally on the guide plate 507, it will drive the first limiting body 511 and the second limiting body 512 to move together. When the slider 508 moves backward, the upper end of the second limiting body 512 will abut against the tooth groove, thereby pushing the transmission toothed belt 505 to move, and further driving the conveyor belt 103 to move. When the slider 508 moves forward, the bottom of the first limiting body 511 is located on the upper surface of the lifting plate 509, and the roller 5111 moves along the upper surface of the lifting plate 509, so that the upper end of the first limiting body 511 cannot retract into the limit hole 510. At this time, the upper end of the first limiting body 511 drives the transmission toothed belt 505 to displace in the reverse direction until the bottom of the first limiting body 511 disengages from the upper surface of the lifting plate 509 and contacts the bottom of the groove 506, and the upper end of the first limiting body 511 retracts into the limit hole 510. At this time, the transmission toothed belt 505 presses the second limiting body 512, causing the upper limit post 5123 at the upper end of the second limiting body 512 to retract into the corresponding limit hole 510, resulting in that neither the first limiting body 511 nor the second limiting body 512 can drive the transmission toothed belt 505 to move, and the transmission toothed belt 505 is temporarily stationary. Until the slider 508 resets, the pushing component continues to push the slider 508 backward to continue the next round of pushing and pulling operations on the transmission toothed belt 505.

[0037] In this process, the backward movement distance is greater than the forward movement distance, achieving the effect that the forward displacement distance of the fitting is greater than the reverse displacement distance. During the reciprocating movement, it is necessary to ensure that the laser does not exceed 2 seconds at the same position of the fitting, so as to ensure that the fitting can be evenly rust-removed, effectively avoiding the problem that the temperature of the fitting rises due to the laser shining on one place for a long time, resulting in the deformation of the fitting.

[0038] The pushing component is composed of a transmission shaft 502 rotatably arranged inside the mounting box frame 1. A second servo motor 501 for driving the transmission shaft 502 to rotate is fixedly arranged on one side of the mounting box frame 1. A first connecting rod 503 is eccentrically fixedly arranged on the transmission shaft 502. A second connecting rod 504 is rotatably arranged on one side of the slider 508. The first connecting rod 503 and the second connecting rod 504 are movably connected, and the length of the second connecting rod 504 is greater than that of the first connecting rod 503. During use, the second servo motor 501 drives the first connecting rod 503 to rotate along the axis, and the first connecting rod 503 drives one end of the second connecting rod 504 to rotate, thereby performing the actions of pushing and dragging on the second connecting rod 504, achieving the effect of the slider 508 moving repeatedly, and providing a stable power source for the entire reciprocating driving mechanism 5.

[0039] It should be noted that two sets of reciprocating driving mechanisms 5 are provided and symmetrically arranged on both sides of the mounting box frame 1 to ensure the stability during transportation.

[0040] In a specific embodiment, a shovel plate 102 matching the conveyor belt 103 is further arranged at the end of the conveying end of the mounting box frame 1, and the upper surface of the shovel plate 102 is arranged in an inclined plane. The conveyor belt 103 can centrally transport the fittings above the shovel plate 102, facilitating the staff to collect them. A support frame 2 is arranged at the bottom of the mounting box frame 1 to increase the horizontal height of the mounting box frame 1, facilitating the staff to place and collect the fittings, and further improving the practicability and convenience of the entire device.

[0041] The laser rust-removing component 3 of the device realizes the movement along an arc path through the arc-shaped moving mechanism 4. After the device is started, the first servo motor 405 fixed on the fixed frames 401 on both sides of the mounting box frame 1 starts to work, driving a set of rotating shafts 404 to rotate. Since a second transmission belt 407 is arranged between the two sets of rotating shafts 404, the rotation of one set of rotating shafts 404 will drive the other set of rotating shafts 404 to rotate in the same direction through the second transmission belt 407.

[0042] A first transmission belt 406 is wound around the side of the rotating shaft 404, and a groove body matched with the first transmission belt 406 is opened around the rotating shaft 404 to ensure that the first transmission belt 406 is stably wound. The bottom of the first transmission belt 406 is slidably matched with the corresponding side of the arc-shaped guide rail 403, and the free end is fixedly connected with the corresponding side of the laser rust removal component 3. When the rotating shaft 404 rotates, one group of rotating shafts 404 tightens the first transmission belt 406 on the side, and the other group of rotating shafts 404 releases the first transmission belt 406 on the side, thereby driving the laser rust removal component 3 to move along the arc-shaped guide rail 403. The first servo motor 405 reciprocates regularly, so that the laser rust removal component 3 reciprocates along the arc-shaped guide rail 403, thereby achieving the effect of moving along the arc path, scanning and cleaning the accessories at multiple angles, and improving the quality of rust removal.

[0043] Working principle: After the staff places multiple groups of accessories evenly and tightly on the conveyor belt 103, the second servo motor 501 is started. The second servo motor 501 drives the first connecting rod 503 to rotate along the axis. The first connecting rod 503 drives one end of the second connecting rod 504 to rotate, thereby pushing and dragging the second connecting rod 504, and completing the effect of repeatedly moving the slider 508 back and forth through the second connecting rod 504.

[0044] When the slider 508 moves back and forth laterally on the guide plate 507, it will drive the first limiter 511 and the second limiter 512 to move together. When the slider 508 moves backward, the upper end of the second limiter 512 will abut against the tooth groove, thereby pushing the transmission toothed belt 505 to move, and then driving the conveyor belt 103 to move. When the slider 508 moves forward, the bottom of the first limiter 511 is located on the upper surface of the lifting plate 509, and the roller 5111 moves along the upper surface of the lifting plate 509, so that the upper end of the first limiter 511 cannot be retracted into the limit hole 510. At this time, the upper end of the first limiter 511 drives the transmission toothed belt 505 to move in the opposite direction until the bottom of the first limiter 511 is separated from the upper surface of the lifting plate 509 and contacts the bottom of the groove 506, and the upper end of the first limiter 511 is retracted into the limit hole 510. At this time, the transmission toothed belt 505 squeezes the second limiting body 512, so that the upper limit post 5123 at the upper end of the second limiting body 512 retracts into the corresponding limiting hole 510, resulting in the first limiting body 511 and the second limiting body 512 being unable to drive the transmission toothed belt 505 to move, and the transmission toothed belt 505 temporarily stops. Until the slider 508 is reset, the pushing assembly continues to push the slider 508 backwards, and continues the next round of pushing and pulling back operations on the transmission toothed belt 505. In this process, since the pushing distance is greater than the pulling back distance, the accessory moves forward as a whole.

[0045] During the reciprocating movement of the fitting, the laser rust removal component 3 performs reciprocating scanning on it to ensure uniform and efficient rust removal on the surface of the fitting. Specifically, the first servo motor 405 starts to work, driving a set of rotating shafts 404 to rotate. With the transmission of the second transmission belt 407, when a set of rotating shafts 404 rotates, it will drive another set of rotating shafts 404 to rotate in the same direction. When the rotating shafts 404 rotate, a set of rotating shafts 404 tightens the first transmission belt 406, and another set of rotating shafts 404 releases the first transmission belt 406, thereby driving the laser rust removal component 3 to move. The power component rotates reciprocally at regular intervals, causing the laser rust removal component 3 to reciprocate, moving along an arc path to perform multi-angle scanning and cleaning on the fitting, improving the rust removal quality. At the same time, strictly control the irradiation time of the laser at the same position of the fitting not to exceed 2 seconds to prevent the fitting from deforming due to excessive local temperature.

[0046] The device is equipped with an optical end sensor that can sense the position of the fitting in real time. When the fitting reaches the specified position, the sensor timely controls the stop and start of the laser rust removal component 3 to avoid energy waste. A shovel plate 102 is provided at the conveying end of the device, and the upper surface of the shovel plate 102 is inclined. The conveyor belt 103 centrally transports the fittings above the shovel plate 102 for easy collection by the staff. After the rust removal operation is completed, if the back of the fitting still needs to be rust-removed and cleaned, it can be continuously and closely placed on the conveyor belt 103 with the surface to be rust-removed facing up for secondary rust removal operation.

[0047] The above discloses only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
