Description

Technical Field

[0001] This utility model relates to the field of steel rust removal technology, specifically a rust removal device for automobile manufacturing steel. Background Technology

[0002] An automobile is a power-driven, non-rail-borne vehicle with four or more wheels, primarily used for transporting people and goods, towing other vehicles, or for special purposes. Steel is used extensively in automobile manufacturing. This steel is formed by pressure processing of ingots, billets, or finished steel into specific shapes, sizes, and properties, which can be categorized as cold working and hot working based on the processing temperature. Before being used in automobile production, steel must undergo rust removal to ensure quality and performance, removing surface oxide layers and other impurities. This process is crucial for ensuring the smooth operation of subsequent manufacturing processes and the quality of the final product, as any residual rust can affect the effectiveness of critical processes such as welding and painting, thereby reducing the overall durability and appearance of the vehicle. Effective rust removal significantly improves material utilization and product quality, meeting the high standards required by the automotive industry.

[0003] Chinese patent (authorization announcement number: CN108723961A, authorization announcement date: 2018.11.02) proposes a rust removal device for automobile manufacturing steel. The technical solution is as follows: A rust removal device for automobile manufacturing steel includes a base, a lifting device, a fine-tuning device, a first support rod, a first bearing, a grinding wheel, a second motor, a connecting plate, a fixing block, and a guide rod. A slide rail is installed on the upper left of the base, and a slider is slidably mounted on the slide rail. A fourth support rod is installed on the left side of the slider, and a third bearing is installed below the fourth support rod. A third rotating shaft is installed inside the third bearing. The continuous rotation of the motor drives the grinding wheel to rotate continuously, grinding the steel. Simultaneously, the first rocker arm is manually rotated to move the grinding wheel left and right, thoroughly cleaning the steel. This eliminates the need for manual labor, as one hand holds a cloth while the other supports the steel, saving time and reducing labor intensity.

[0004] The aforementioned rust removal device for automobile manufacturing mainly relies on mechanical grinding to remove rust from steel. It requires manual adjustment of height and movement trajectory. Furthermore, the aforementioned rust removal device lacks an automated flipping mechanism, requiring manual flipping of the steel to remove rust from the other side. This results in high labor intensity and low rust removal efficiency. Therefore, we propose a rust removal device for automobile manufacturing steel. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a rust removal device for automobile manufacturing steel, including a device body 1, with an inlet 3 and an outlet 4 respectively opened on the left and right sides of the device body 1, and roller conveyor belts 11 installed on both the left and right sides inside the device body 1, with an anti-fall component 6 installed between the two sets of roller conveyor belts 11, and installation cavities 2 provided on both the front and rear sides inside the device body 1, with a flipping component 7 installed inside both sets of installation cavities 2, and a rust removal component 5 and a dust removal component 8 respectively installed on the middle of the top side and the right side of the top of the device body 1.

[0023] Steel enters the equipment body 1 through the feed inlet 3 and is conveyed by the left roller conveyor belt 11 to the space between the two sets of roller conveyor belts 11. When the steel crosses the two sets of roller conveyor belts 11, the two sets of roller conveyor belts 11 stop running, the fall prevention component 6 descends and retracts, and the top rust removal component 5 begins to remove rust from the steel. After the rust removal is completed, the flipping component 7 in the installation cavity 2 flips the steel over, and the rust removal component 5 performs rust removal again. During this period, the dust removal component 8 collects and discharges the fumes generated during the rust removal. The rust-removed steel is then conveyed by the roller conveyor belt 11 to the discharge outlet 4 for discharge.

[0024] The flipping assembly 7 includes a lifting module 71, which is fixedly installed inside the mounting cavity 2. A second sliding plate 72 is slidably installed on the lifting module 71. A push-pull cylinder 73 is fixedly installed on the right side of the second sliding plate 72. A first mounting plate 74 is fixedly connected to the output shaft end of the push-pull cylinder 73. A second mounting plate 76 is fixedly installed on the first mounting plate 74. A clamping cylinder 77 is fixedly installed on the rotating end of the second mounting plate 75. Two sets of clamping claws 78 are installed on the output end of the clamping cylinder 77.

[0025] When the flipping assembly 7 is working, the lifting module 71 is fixed in the mounting cavity 2. The sliding plate 72 is driven to slide up and down along the lifting module 71 to adjust to the height of the steel. Then, the push-pull cylinder 73 extends its output shaft, driving the mounting plate 74 and the connected rotary cylinder 75 and mounting plate 76 to move towards the steel. When the clamping claws 78 are close to the steel, the clamping cylinder 77 drives the two sets of clamping claws 78 to clamp the steel. Then, the lifting module 71 drives the steel to move upward, leaving space for the steel to flip. After reaching the predetermined position, the rotary cylinder 75 drives the mounting plate 76 to rotate, realizing the flipping of the steel. Then, it is placed back between the two sets of roller conveyor belts 11.

[0026] The fall arrestor 6 includes a fixing plate 61, which is fixedly connected between the front and rear sides of the equipment body 1. A lifting cylinder 62 is fixedly installed on the top center of the fixing plate 61. A U-shaped plate 63 is fixedly connected to the output shaft end of the lifting cylinder 62. A roller 65 is rotatably installed between the front and rear sides of the U-shaped plate 63. Limiting rods 64 are fixedly connected to the front and rear sides of the bottom of the U-shaped plate 63, and the bottom of the limiting rods 64 slides through the fixing plate 61.

[0027] When the anti-fall component 6 is working, the fixing plate 61 is fixed between the front and rear sides inside the equipment body 1. The lifting cylinder 62 is installed on the top side of the fixing plate 61, and its output shaft pushes the U-shaped plate 63 to rise and fall. The rollers 65 on the front and rear sides of the U-shaped plate 63 contact the bottom surface of the steel to provide support force. The bottom limit rod 64 slides along the fixing plate 61 to ensure the stability of the U-shaped plate 63 when it rises and falls.

[0028] The rust removal component 5 includes a laser generator 51, which is located on the top left side of the equipment body 1. A movable module 52 is fixedly installed on the top side inside the equipment body 1. A sliding plate 53 is slidably installed on the movable module 52. A laser rust removal head 54 is installed on the left side of the sliding plate 53. A transmission pipe connects the laser rust removal head 54 and the laser generator 51.

[0029] When the rust removal component 5 is running, the laser generator 51 is located on the top left side of the equipment body 1 and supplies energy to the laser rust removal head 54 through the transmission tube. The moving module 52 on the top side inside the equipment body 1 drives the sliding plate 53 to slide laterally, which drives the laser rust removal head 54 to move along the steel surface, so as to realize laser focused rust removal and accurately peel off the rust layer on the steel surface.

[0030] The dust removal component 8 includes a fan 82, which is fixedly installed on the top right side of the equipment body 1. A smoke exhaust port 81 is also provided on the top right side of the equipment body 1. The input end of the fan 82 is fixedly connected to the smoke exhaust port 81 through a pipe, and the output end of the fan 82 is fixedly connected to a smoke exhaust pipe 83.

[0031] When the dust removal component 8 is working, since the fan 82 is fixed on the top right side of the equipment body 1 and connected to the exhaust port 81 through the pipe, when the fan 82 is running, the suction generated will draw the dust generated during the rust removal process into the exhaust port 81 and then discharge it out of the equipment through the exhaust pipe 83, thus completing the dust removal operation.

[0032] An image recognition sensor 10 is also installed on the top inner side of the device body 1 to collect images of the steel surface in real time and transmit the data to the controller 9 on the front left side.

[0033] A controller 9 is installed on the front left side of the equipment body 1. The controller 9 processes and analyzes the image to determine the distribution of rust layer on the steel and the need for turning over, and then controls the start-up and operation parameters of components such as the turning over component 7 and the rust removal component 5.

[0034] Several anti-slip grooves are provided on the side of the two sets of clamping claws 78 that are close to each other, which increases the friction with the steel surface and prevents the steel from slipping due to insufficient clamping during the flipping process, thus ensuring the stability of the flipping operation.

[0035] Brake casters 12 are installed at the four corners of the bottom of the equipment body 1 to support the movement of the equipment. When the equipment is positioned in the working position, the casters are fixed by locking the brake mechanism to prevent the equipment from shifting during the rust removal operation and to ensure the rust removal accuracy.

[0036] Working principle: Steel enters the equipment body 1 through the feed inlet 3 and is conveyed by the left roller conveyor belt 11 to the space between the two sets of roller conveyor belts 11. Since the fixed plate 61 is fixed between the front and rear sides inside the equipment body 1, the lifting cylinder 62 is installed on the top side of the fixed plate 61. Its output shaft pushes the U-shaped plate 63 to rise and fall. The rollers 65 on the front and rear sides of the U-shaped plate 63 contact the bottom surface of the steel, providing support to prevent the steel from falling. The bottom limit rod 64 slides along the fixed plate 61 to ensure the stability of the U-shaped plate 63 when it rises and falls. When the steel crosses the two sets of roller conveyor belts 11, the two sets of roller conveyor belts 11 stop running, and the rollers 65 are lowered and retracted under the action of the lifting cylinder 62.

[0037] Since the laser generator 51 is located on the top left side of the equipment body 1, it supplies energy to the laser rust removal head 54 through the transmission tube. The moving module 52 on the top side inside the equipment body 1 drives the sliding plate 53 to slide laterally, which in turn moves the laser rust removal head 54 along the steel surface to achieve laser focused rust removal and accurately peel off the rust layer on the steel surface. After rust removal is completed, since the lifting module 71 is fixed in the installation cavity 2, the sliding plate 72 is driven to slide up and down along the lifting module 71 to adjust to the height of the steel. Then, the push-pull cylinder is used. 73 extends the output shaft, driving mounting plate 1 74 and connected rotary cylinder 75 and mounting plate 2 76 to move towards the steel. When the clamping claw 78 is close to the steel, the clamping cylinder 77 drives the two sets of clamping claws 78 to clamp the steel. Then the lifting module 71 drives the steel to move upward, leaving space for the steel to flip. After reaching the predetermined position, the rotary cylinder 75 drives mounting plate 2 76 to rotate, realizing the flipping of the steel. Then it is placed back between the two sets of roller conveyor belts 11, and the laser rust removal head 54 performs rust removal treatment again.

[0038] The dust generated during the rust removal process is drawn into the exhaust port 81 by the suction force generated by the start of the fan 82, and then discharged outside the equipment through the exhaust pipe 83, thus completing the dust removal operation. The rust-removed steel is then transported to the discharge port 4 by the roller conveyor belt 11.
