Description

Technical Field

[0001] The invention relates to the technical field of steel back processing and feeding, and in particular to an automatic steel back feeding device and method for producing automobile brake pads. Background Art

[0002] After the production, the brake pad is supported by the steel back. During the stamping process, the steel back is usually transported and loaded by a robot with a suction cup to suck the steel plate. In particular, cold-rolled steel plate has become the preferred material for the steel back of the brake pad due to its surface quality, dimensional accuracy, mechanical properties and processing performance. In the rolling process, cold-rolled steel coils usually use coolant and anti-rust oil. If some of them are not cleaned thoroughly, they are easy to remain on the surface of the steel plate. During the flattening and transportation process, it is easy to mix with dust to form sludge or oil stains. After the plate is flattened to the required size, it is uncertain which plate with coolant and anti-rust oil or sludge and oil stains is located in the pile. This results in insufficient adsorption of the suction cup when encountering such steel plates when the suction cup is sucked and loaded, causing the steel plate to fall or shift in position during the feeding and transportation process, destroying the continuity of production and processing, and reducing processing efficiency.

[0003] For example, the automatic steel back feeding device for automobile brake pad production disclosed by announcement number CN117682303B solves the problem of power cord, air pipe and synchronous belt pulling when the current handling robot moves by remote mechanical control of the electric motor. However, when the steel plate is fed by this feeding method, the movement is mainly achieved by the meshing of gear racks, which requires part of the rack to be located in the stamping machine, affecting the mold clamping of the stamping machine. The automatic steel back feeding device for automobile brake pad production disclosed by announcement number CN116424771A can be automatically sucked by the suction cup, but the shape of the suction cup is fixed. The suction force can only be changed by changing the power of the air compressor. The process of changing the output power of the air compressor takes a long time to finally be reflected at the suction cup, affecting production efficiency.

[0004] Therefore, an automatic steel back feeding device and method for producing automobile brake pads are proposed. Summary of the invention

[0035] The present invention provides a steel back automatic feeding device and method for automobile brake pad production. Compared with the prior art, it has the following beneficial effects:

[0036] (1) The automatic steel back feeding device and method for automobile brake pad production uses a control box to control the feeding unit and the suction cup to transport the cold-rolled steel plate to be stamped to the stamping machine for steel back processing. In the process of sucking the cold-rolled steel plate, as the feeding unit is lowered, the scraper can clean the suction position before the suction cup sucks the steel plate to avoid oil stains, sludge, and unevenness on the surface of the steel plate, which may cause the suction effect of the suction cup to deteriorate, causing the steel plate to fall or shift during the feeding process and unable to be accurately placed in the stamping machine, affecting the overall progress of automobile brake pad steel back production. At the same time, the scraper can be deflected to the outside of the steel plate when the suction cup sucks the steel plate to avoid blocking the suction cup from sucking the steel plate.

[0037] (2) The automatic steel back feeding device and method for automobile brake pad production, after the image recognition module completes the recognition and judgment, sends a control signal according to the judgment result, controls the extrusion plate to squeeze the edge of the suction cup, so that the edge of the suction cup changes from a round shape to a wavy edge, increases the contact points between the suction cup and the surface, improves the sealing and suction force, and at the same time, the edge presents a slope shape, reduces the air entry, improves the suction force, ensures that the suction cup can firmly adsorb the steel plate, and does not increase the power of the air compressor to increase the suction force. The process of changing the output power of the air compressor takes a long time to finally be reflected at the suction cup, which affects the production efficiency. The device has stronger adaptability and does not need to frequently replace suction cups of different shapes, reducing the time and cost of maintenance and replacement. At the same time, it can avoid the problem of production line shutdown due to the steel plate falling during the feeding process, which delays the production progress.

[0038] (3) The automatic steel back feeding device and method for the production of automobile brake pads, after the image recognition module completes the recognition and judgment, transmits a control signal according to the judgment result, controls the degree to which the edge of the suction cup is folded into a wavy shape according to the amount of oil stains and sludge, dynamically adapts to the different suction conditions on the surfaces of different steel plates, and improves the reliability and stability of the operation.

[0039] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention.

[0059] The gear 26 is fixedly mounted on the output shaft 27 and meshes with the teeth on the side wall of the movable rod 25;

[0060] One end of the support rod 210 is fixedly mounted on the bottom of the fixed plate 2 and the other end is fixedly mounted with a spirally mounted guide block 211;

[0061] One end of the extrusion rod 29 is provided with an inclined surface, and the inclined surface is slidably fitted with the guide block 211 . The sliding contact between the inclined surface and the spirally arranged guide block 211 can drive the fixed sleeve 24 to rotate around the sliding sleeve 21 as the axis.

[0062] During use, the control box 12 is operated to make the feeding unit 1 and the suction cup 11 run to transport the cold-rolled steel plate to be stamped to the stamping machine for steel back processing. In the process of sucking the cold-rolled steel plate, as the feeding unit 1 is lowered, the scraper 251 will contact the steel plate before the suction cup 11. When the scraper 251 contacts the steel plate, the power motor 28 is started to drive the output shaft 27 to rotate, and the output shaft 27 drives the gear 26 to rotate. The gear 26 engages with the teeth to drive the movable rod 25 to rotate. The fixed sleeve 24 provides support force to the movable rod 25. Driven by the gear 26, the movable rod 25 drives the scraper 251 to scrape the area on the surface of the steel plate that is about to be adsorbed by the suction cup 11, and scrapes the sludge remaining on the surface of the steel plate due to rolling and transportation. As the feeding unit 1 continues to move downward, the fixed sleeve 24 drives the sliding rod 23 to move upward, and the sliding rod 23 drives the guide plate 22 to move upward. The sliding sleeve 22 and the sliding sleeve 21 are in sliding cooperation, so that the sliding rod 23 and the guide plate 22 can only move linearly during the upward movement, and the fixed sleeve 24 synchronously drives the output shaft 27, the power motor 28, and the motor box to move upward, and the motor box drives the extrusion rod 29 to move upward, and the support rod 210 provides a supporting force to the guide block 211, and the extrusion rod 29 and the guide block 211 are in sliding cooperation, so that the extrusion rod 29 moves along the guide block 211, so that the extrusion rod 29 drives the fixed sleeve 24, the sliding rod 23, the guide plate 22, and the sliding sleeve 21 to rotate with the sliding sleeve 21 as the axis, so that the fixed sleeve 24 drives the movable rod 25 to move from just above the steel plate to the outside of the steel plate, and the steel plate is sucked by the suction cup 11, and the suction cup 11 is driven by the feeding unit 1 to move to the stamping machine, and the steel plate is placed at the stamping machine for steel back processing, and the feeding unit 1 is reset to the steel plate suction position to suck the next steel plate;

[0063] In another embodiment different from the above-mentioned embodiment, the detection assembly further includes: a sliding block 252, a camera 253, a spring 254, a sliding rope 255, a movable seat 256, a connecting plate 257, and an electric push rod 258.

[0064] One end of the camera 253 is fixed on the side wall of the sliding block 252 and is located below the movable rod 25 for recording the cleaning status of the scraper 251;

[0065] One end of the sliding block 252 is T-shaped and slidably penetrates the movable rod 25 to provide support for the camera 253. A sliding rope 255 is fixedly installed on the side wall of the sliding block 252. One end of the sliding rope 255 is slidably penetrates the movable rod 25. A spring 254 is fixedly installed on the side wall of the sliding block 252. The other end of the spring 254 is fixed in the movable rod 25 to provide the elastic force required for the sliding block 252 to reset.

[0066] One end of the sliding rope 255 is fixedly mounted on the movable seat 256, and one end of the movable seat 256 is movably mounted on the bottom of the connecting plate 257 through a bearing. An electric push rod 258 for driving the connecting plate 257 to rise is fixedly mounted on the bottom of the connecting plate 257, and the bottom of the electric push rod 258 is fixedly mounted on the top of the motor box. The bottom of the extrusion rod 29 is fixedly mounted on the top of the connecting plate 257.

[0067] When in use, the motor box provides support force for the electric push rod 258, the electric push rod 258 provides support force for the connecting plate 257, and the connecting plate 257 provides support force for the extrusion rod 29. When the scraper 251 contacts the steel plate, the feeding unit 1 stops moving down for 3-5S and then runs again. During the process, the power motor 28 drives the movable rod 25 to rotate 2 to 3 circles and stops. The electric push rod 258 is started, and the electric push rod 258 drives the connecting plate 257 to move up, and the connecting plate 257 drives the sliding rope 255 to move. The sliding rope 255 slides in the movable rod 25 and drives the sliding block 252 to move. The sliding block 252 and the movable rod 25 slide together, so that the sliding block 252 can only move in a straight line when moving. When the movable rod 25 rotates under the drive of the gear 26, the sliding rope 255 will rotate with the movable seat 256 as the axis without The sliding block 252 drives the camera 253 to move, and the camera 253 records the total amount of oil and sludge in the scraper 251, which is identified and determined by the image recognition module in the control box 12. In the process of the sliding block 252 moving from one end of the sliding groove to the other end, the connecting plate 257 synchronously drives the extrusion rod 29 to move upward, so that the fixed sleeve 24 deflects with the sliding sleeve 21 as the axis. When the extrusion rod 29 moves upward, the feeding unit 1 synchronously drives the suction cup 11 to move downward to absorb the steel plate. In the process of the feeding unit 1 placing the current steel plate on the stamping machine and resetting it to the position where the steel plate is absorbed, the electric push rod 258 is controlled to reset to the initial position, so that the movable rod 25 is reset to the bottom of the suction cup 11 again. After the sliding rope 255 no longer obtains tension, the sliding block 252 is also reset under the action of the spring 254.

[0068] In another embodiment different from the aforementioned embodiment, a rotary joint connected to an air pipe is provided on the connecting plate 257, and then the other end of the rotary joint is connected to a nozzle through a tee and an air pipe, and the nozzle is fixed directly below the camera 253 and aimed at the scraper 251. When the camera 253 is reset after image recognition, air is supplied to the nozzle so that the nozzle blows away the sludge in the scraper 251 to prevent the sludge from remaining in the scraper 251 and affecting the next round of image recognition. At the same time, a collection box can be provided to collect the blown sludge.

[0069] Embodiment 2: The technical solution of this embodiment is different from that of embodiment 1 and includes: the feeding unit 1 is provided with:

[0070] The adjusting component is located just above the suction cup 11 and adjusts the shape of the suction cup 11 according to the detection result. The adjusting component includes: a positioning plate 3, a guide rod 31, a magnetic ring 32, a fixed electromagnet 33, a fixing seat 34, an upper connecting rod 35, a lower connecting rod 36, a squeezing plate 37, and a fixing rope 38;

[0071] One end of the positioning plate 3 is fixedly mounted on the support of the suction cup 11, a fixed electromagnet 33 is fixedly mounted on the bottom of the guide rod 31, and the fixed electromagnet 33 is located directly below the magnetic ring 32. A fixed rope 38 is fixed on the bottom of the positioning plate 3, and one end of the fixed rope 38 is fixed on the lower connecting rod 36;

[0072] One end of the upper connecting rod 35 is hinged to a movable shaft through a torsion spring, and the movable shaft is movably mounted on a fixed seat 34 through a bearing. One end of the fixed seat 34 is fixedly mounted on a magnetic ring 32. A guide rod 31 for guiding is slidably inserted in the magnetic ring 32, and a positioning plate 3 is fixedly mounted on one end of the guide rod 31.

[0073] One end of the lower connecting rod 36 is fixedly mounted on the extrusion plate 37 to provide support force for the extrusion plate 37, and the other end is hinged to a rotating shaft through a torsion spring, and the rotating shaft is movably mounted on the upper connecting rod 35 through a bearing;

[0074] The side wall of the pressing plate 37 abuts against the surface of the suction cup 11 .

[0075] When in use, after the image recognition module completes the recognition and judgment, a control signal is transmitted according to the judgment result to control whether the fixed electromagnet 33 needs to be energized. When the fixed electromagnet 33 is energized, a magnetic attraction force is generated between the fixed electromagnet 33 and the magnetic ring 32, and the magnetic ring 32 and the guide rod 31 are slidably matched. The positioning plate 3 provides a supporting force for the guide rod 31, so that the magnetic ring 32 can only move in a straight line along the guide rod 31. During the downward movement of the magnetic ring 32, the fixed seat 34 is simultaneously driven to move, and the fixed seat 34 drives the upper connecting rod 35 to move, and the upper connecting rod 35 drives the lower connecting rod 31 to move. The rod 36 moves, and the lower connecting rod 36 drives the squeezing plate 37 to move, and one end of the fixing rope 38 is fixed on the positioning plate 3, and the other end of the fixing rope 38 is fixed on the lower connecting rod 36. The length of the fixing rope 38 remains unchanged, so that the height of the connection between the lower connecting rod 36 and the fixing rope 38 remains unchanged. When the lower connecting rod 36 moves downward under the drive of the upper connecting rod 35, the lower connecting rod 36 is squeezed to flip around the rotating axis as the axis center, and the upper connecting rod 35 is also flipped around the fixed axis as the axis center, so that the squeezing plate 37 squeezes the edge of the suction cup 11, so that the edge of the suction cup 11 changes from a round shape to a wavy edge.

[0076] Embodiment 3: The technical solution of this embodiment is different from that of embodiment 2 in that: the adjustment assembly further includes: a fixed rod 4, a magnet 41, a sliding electromagnet 42, a stop rod 43, a baffle 44, a second spring 45, and a stop block 46;

[0077] One end of the fixing rod 4 is fixedly mounted on the bottom of the fixing plate 2 to provide support force for the blocking rod 43;

[0078] One end of the blocking rod 43 is slidably disposed in the fixed rod 4, and the other end is located between the magnetic ring 32 and the fixed electromagnet 33 to limit the moving distance of the magnetic ring 32;

[0079] The top of the stopper 46 is fixed to the bottom of the magnetic ring 32 and cooperates with the stopper rod 43 to adjust the turning amount of the extrusion plate 37;

[0081] When in use, after the image recognition module completes the recognition and judgment, a control signal is transmitted according to the judgment result, and the degree to which the edge of the suction cup is folded into a wavy shape is controlled according to the amount of oil stains and sludge. By energizing the sliding electromagnet 42, the magnetic repulsion between the sliding electromagnet 42 and the magnet 41 is caused, or the sliding electromagnet 42 is directly de-energized. At this time, in the process of the magnetic ring 32 driving the lower connecting rod 36 to move, the magnetic ring 32 moves along the guide rod 31 to drive the stopper 46 to move, and the stopper 46 slides with the stopper rod 43, thereby squeezing the stopper rod 43 to move, so that the stopper rod 43 is removed from between the magnetic ring 32 and the fixed electromagnet 33. The number of magnetic rings 32 that can pass through the stopper rod 43 is controlled according to the amount of oil stains and sludge, so that the degree to which the edge of the suction cup 11 becomes wavy is controlled. After the feeding and conveying of the current steel plate is completed, with the resetting of the magnetic ring 32, the stopper rod 43 is also reset to the initial state under the action of the spring 45.
