Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a brake pad hot-pressed steel back feeding device. Background Technology

[0002] Brake pads are the most critical safety component in a car's braking system, determining the effectiveness of braking. Brake pads generally consist of a steel plate, an adhesive heat-insulating layer, and friction pads. The heat-insulating layer is made of a non-heat-conducting material for heat insulation. The friction pads are composed of friction materials and adhesives, and during braking, they are pressed against the brake disc and brake drum to generate friction, thereby achieving the purpose of decelerating and braking the vehicle.

[0003] In the brake pad production process, various friction materials and adhesives need to be added to the press mold, and then the steel backing is placed into the press mold. Finally, the brake pad is formed by hot pressing. Nowadays, most factories have achieved automated production. In the automated production process, the steel backing needs to be fed so that it can be put into the hot pressing mold. However, the existing steel backing feeding device generally grabs the steel backing directly from the steel backing stack and transports it directly to the hot pressing mold for placement. This feeding method produces a large error, and the steel backing may not be able to be placed into the hot pressing mold, resulting in production interruption and affecting the production of brake pads.

Detailed Implementation

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figures 1 to 3 As shown, a brake pad hot pressing steel backing feeding device includes a base 1, which is slidably mounted on a ground rail 2. A placement component 3 is slidably mounted on the base 1 for holding the steel backing. The base 1 is also equipped with a lifting component 4, a primary gripping component 5, a positioning component 6, and a secondary gripping component 7. The lifting component 4 is located on one side of the placement component 3 for lifting the steel backing. The primary gripping component 5 is located above the placement component 3 and directly above the lifting component 4 for gripping the steel backing and placing it on the positioning component 6. The positioning component 6 is used for positioning the steel backing. The secondary gripping component 7 is located above the positioning component 6 and grips the steel backing on the positioning component 6 and transports it to the hot pressing mold. In this invention, multiple steel backs are stacked on the placement component 3. The primary gripping component 5 can grip the steel backs stacked on the placement component 3 and transport them to the positioning component 6. As the primary gripping component 5 continuously removes the steel backs from the placement component 3, the height of the stacked steel backs will decrease, causing the primary gripping component 5 to be unable to grip them. At this time, the lifting component 4 can lift the steel backs on the placement component 3, increasing the height of the steel backs, allowing the primary gripping component 5 to continue gripping. After the steel backs are gripped onto the positioning component 6, they can be positioned on the positioning component 6. The position of the steel backs after positioning is more accurate. The secondary gripping component 7 grips the positioned steel backs and transports them to the hot press mold. Because the steel backs have been positioned, the secondary gripping component 7 can place the steel backs more accurately into the hot press mold, avoiding the steel backs being unable to be placed.

[0022] Furthermore, the ground rail 2 consists of two horizontally arranged slide rails, which are fixedly mounted on the ground. A slider is fixedly mounted on the bottom of the base 1, and the slider at the bottom of the base 1 slides on the ground rail 2, making the movement of the base 1 more stable. A rack is also fixedly mounted between the two slide rails, and the rack is parallel to the ground rail 2. A motor is fixedly mounted on the base 1, and a gear is fixedly connected to the output shaft of the motor. The gear meshes with the rack, and the motor on the base 1 drives the gear to rotate, allowing the base 1 to slide along the length of the rack.

[0023] like Figure 4As shown, the placement assembly 3 includes a placement rack 8, which is slidably mounted on the machine base 1. The placement rack 8 slides horizontally along the machine base 1. A placement plate 9 is provided at the lower part of the placement rack 8 for holding steel backings. Multiple sets of placement plates 9 are arranged in the horizontal direction. In this embodiment, multiple sets of placement plates 9 are provided on the placement rack 8, and each set of placement plates 9 can hold steel backings. Therefore, multiple sets of steel backings of different models can be placed on the placement rack 8, enabling the production line to produce brake pads of multiple specifications simultaneously. A baffle 29 is fixedly provided between two adjacent sets of placement plates 9. The lifting assembly 4 is located on one side of the placement assembly 3. When the primary gripping assembly 5 grips the steel backing, the placement rack 8 slides horizontally on the machine base 1, causing the placement plate 9 containing the corresponding steel backing to move below the primary gripping assembly 5. At this time, the lifting assembly 4 lifts the corresponding steel backing, enabling the primary gripping assembly 5 to grip the steel backing normally.

[0024] It should be noted that a first slide rail is fixedly installed on the base 1, and a first slider is fixedly installed at the bottom of the placement rack 8. The first slider is slidably installed on the first slide rail, so that the placement rack 8 can slide horizontally on the base 1. In order to drive the placement rack 8 to slide horizontally, a second lead screw is rotatably installed on the base 1. The second lead screw is driven by a motor fixedly installed on the base 1. A second lead screw nut is installed at the bottom of the placement rack 8. The second lead screw nut is threadedly connected to the lead screw. The placement rack 8 can move horizontally by rotating the second lead screw.

[0025] Furthermore, the placement rack 8 is provided with multiple sets of placement plates 9, each set of placement plates 9 having two plates. Multiple screws 10 are rotatably mounted on the placement rack 8, the number of screws 10 being the same as and corresponding to the number of sets of placement plates 9. The screws 10 are horizontally mounted and are double-threaded screws. The two placement plates 9 in each set are threadedly connected to one of the screws 10. The two placement plates 9 are located at the two threads of the screw 10 with opposite directions of rotation. By rotating the screw 10, the two placement plates 9 can be moved closer to each other or further away from each other, thereby adjusting the distance between the two placement plates 9 to accommodate steel backings of different specifications.

[0026] It should be noted that, in order to make the sliding of the placement plate 9 more stable, a second slide rail is fixedly installed on the placement frame 8, and a second slider is fixedly installed on the placement plate 9. The second slider is slidably installed on the second slide rail, so that the placement plate 9 can move along the second slide rail during the movement, making the sliding of the placement plate 9 more stable.

[0027] like Figure 5As shown, the lifting assembly 4 includes a lifting frame 11, which is fixedly mounted on the base 1 and located on one side of the placement frame 8. A lifting plate 12 is slidably mounted on the lifting frame 11 and slides vertically along the lifting frame 11. The lifting plate 12 is located below the placement plate 9. In this embodiment, when the placement plate 9 holding the steel back moves to the lifting plate 12, the placement plate 9 is above the lifting plate 12. As the steel back is removed from the placement plate 9, the height of the steel back decreases. In order for the primary gripping assembly to continue to grip the steel back normally, the steel back needs to be lifted so that the uppermost steel back can contact the primary gripping assembly. At this time, the lifting plate 12 can slide upward along the lifting frame 11, and during the sliding process, the steel back placed on the placement plate 9 can be lifted, increasing the height of the steel back.

[0028] Furthermore, a first lead screw 13 is rotatably mounted on the lifting frame 11. The first lead screw 13 is connected to a motor fixed on the lifting frame 11, thereby driving the first lead screw 13 to rotate. The lifting plate 12 is threadedly connected to the first lead screw 13. When the first lead screw 13 rotates, it can drive the lifting plate 12 to slide up and down, raising or lowering the steel back.

[0029] It should be noted that, in order to make the sliding of the lifting plate 12 more stable, a third slide rail is fixedly installed on the lifting frame 11. The third slide rail is parallel to the first lead screw 13. A third slider is fixedly installed on the lifting plate 12. The third slider is slidably connected to the third slide rail, so that the sliding of the lifting plate 12 is more stable and smooth.

[0030] like Figure 6 As shown, the single-grip component 5 includes a first fixed frame 14, which is fixedly mounted on the base 1 and located above the placement component 3. A material-grabbing frame 15 is slidably mounted on the first fixed frame 14, and a material-grabbing plate 16 is vertically slidably mounted on the material-grabbing frame 15. A first electromagnet 30 is mounted on the material-grabbing plate 16. In this embodiment, when the placement frame 8 slides on the base 1 to move the steel back to be gripped to directly below the material-grabbing frame 15, the material-grabbing plate 16 slides downward along the material-grabbing frame 15, causing the first electromagnet 30 on the material-grabbing plate 16 to contact the uppermost steel back. The first electromagnet 30 is energized to attract the steel back, and the material-grabbing plate 16 slides upward. Subsequently, the material-grabbing frame 15 slides along the first fixed frame 14 to move to the positioning component 6. After the first electromagnet 30 is de-energized, the steel back falls onto the positioning component 6 for positioning.

[0031] It should be noted that two first pulleys are rotatably mounted on the first fixed frame 14. One of the first pulleys is connected to a motor fixedly mounted on the first fixed frame 14. A first belt is wound between the two pulleys. The material picker 15 is fixedly connected to the first belt. The first belt is rotated by the motor driving the first pulley. During the rotation of the first belt, the material picker 15 can slide between the two first pulleys. The forward and reverse rotation of the motor makes the material picker 15 reciprocate. In order to make the sliding of the material picker 15 more stable, a fourth slide rail is fixedly mounted on the first fixed frame 14, and a fourth slider is fixedly mounted on the material picker 15. The fourth slider is slidably mounted on the fourth slide rail, so that the material picker 15 can slide along the slide rail during the sliding process.

[0032] Furthermore, a sliding rod 17 is fixedly installed on the material-grabbing plate 16. The sliding rod 17 is vertically slidably mounted on the material-grabbing frame 15. There are two sliding rods 17, which are arranged in parallel. The two sliding rods 17 can make the force on the material-grabbing plate 16 more even. In this embodiment, when the gripping component 5 grips the steel back below the material-grabbing frame 15, the sliding rod 17 on the material-grabbing frame 15 slides vertically downward, driving the material-grabbing plate 16 to slide downward, so that the first electromagnet 30 can contact the uppermost steel back. After the material is picked up, the sliding rod 17 drives the material-grabbing plate 16 to slide upward, removing the steel back from the placement component 3, completing one material picking operation.

[0033] It should be noted that two second pulleys are rotatably mounted on the material picking rack 16, and a second belt is wound around the two second pulleys. The second belt is fixedly connected to one of the slide rods 17. One of the second pulleys is connected to a motor fixedly mounted on the material picking rack 15. When the motor drives one of the second pulleys to rotate, it can drive the second belt to rotate, thereby driving the slide rod 17 to slide between the two second pulleys. The slide rod 17 can slide up and down by the forward and reverse rotation of the motor.

[0034] like Figure 7As shown, the positioning component 6 includes a positioning frame 18. A transverse fixing plate 19 and a longitudinal fixing plate 20 are fixedly disposed on the upper end surface of the positioning frame 18. The transverse fixing plate 19 and the longitudinal fixing plate 20 are arranged perpendicularly. A transverse clamping plate 21 is slidably disposed on the positioning frame 18. The transverse clamping plate 21 is arranged parallel to the transverse fixing plate 19. A longitudinal clamping plate 22 is also slidably disposed on the positioning frame 18. The longitudinal clamping plate 22 is arranged parallel to the longitudinal fixing plate 20. In this embodiment, the first material handling assembly 5 removes the steel back from the placement assembly 3 and places it on the upper surface of the positioning frame 18. Then, the transverse clamping plate 21 slides to one side of the transverse fixing plate 19, pushing the steel back to slide to one side of the transverse fixing plate 19. At the same time, the longitudinal clamping plate 22 pushes the steel back to one side of the longitudinal fixing plate 20 until the four sides of the steel back are tightly fitted with the transverse fixing plate 19, the longitudinal fixing plate 20, the transverse clamping plate 21, and the longitudinal clamping plate 22, respectively. After the steel back is clamped, the steel back is accurately positioned. Then, the second gripping assembly 7 can remove the positioned steel back. The position of the steel back after positioning is more accurate and can be accurately placed into the hot press mold for pressing and forming.

[0035] It should be noted that, in order to enable the sliding of the transverse clamping plate 21 and the longitudinal clamping plate 22, a transverse slide groove 31 and a longitudinal slide groove 32 are provided on the positioning frame 18. Two transverse pulleys are rotatably mounted on the positioning frame 18, and transverse belts are wound around the two transverse pulleys. One end of the transverse clamping plate 21 passes through the transverse slide groove 31 and is fixedly connected to the transverse belt. The rotation of the transverse pulleys drives the transverse belt to rotate, thereby causing the transverse clamping plate 21 to slide. Similarly, two longitudinal pulleys are rotatably mounted on the positioning frame 18, and longitudinal belts are wound around the two longitudinal pulleys. One end of the longitudinal clamping plate 22 passes through the longitudinal slide groove 32 and is fixedly connected to the longitudinal belt, so that the longitudinal clamping plate 22 can slide horizontally.

[0036] In another embodiment, the transverse clamping plate 21 and the longitudinal clamping plate 22 can be slid by a cylinder. Two cylinders are fixedly installed on the positioning frame 18. The two cylinders are vertically arranged, and the piston rods of the two cylinders are fixedly connected to the transverse clamping plate 21 and the longitudinal clamping plate 22 respectively. The transverse clamping plate 21 and the longitudinal clamping plate 22 are slid by the extension and retraction of the piston rods of the cylinders, and the sliding direction is perpendicular.

[0037] It should be noted that, in order to make the sliding of the transverse clamping plate 21 and the longitudinal clamping plate 22 more stable, two slide rails are fixedly installed on the positioning frame 18. The two slide rails are vertically arranged, and sliders are fixedly installed on both the transverse clamping plate 21 and the longitudinal clamping plate 22. The sliders on the transverse clamping plate 21 and the longitudinal clamping plate 22 are slidably connected to the two slide rails respectively, thereby making the sliding of the transverse clamping plate 21 and the longitudinal clamping plate 22 more stable.

[0038] It should be further explained that there is one transverse fixing plate 19 and one transverse clamping plate 21, and multiple longitudinal fixing plates 20 and multiple longitudinal clamping plates 22. The longitudinal fixing plates 20 and the longitudinal clamping plates 22 are located between the transverse fixing plates 19 and the transverse clamping plates 21. The longitudinal fixing plates 20 and the longitudinal clamping plates 22 are alternately arranged, so multiple steel backs can be clamped and positioned at the same time, thus improving the positioning efficiency.

[0039] Furthermore, a support frame 23 is fixedly mounted on the base 1, and a positioning frame 18 is slidably mounted on the support frame 23. A third lead screw is horizontally rotatably mounted on the support frame 23, and a third lead screw nut is provided on the positioning frame 18. The third lead screw nut is threadedly connected to the third lead screw, thereby driving the positioning frame 18 to slide horizontally on the support frame 23.

[0040] Furthermore, the support frame 23 is slidably connected to the base 1, and the sliding direction of the support frame 23 is perpendicular to the sliding direction of the positioning frame 18. In order to drive the support frame 23 to slide, a fourth lead screw is horizontally rotatably provided on the base 1, and a fourth lead screw nut is provided on the support frame 23. The fourth lead screw nut is threadedly connected to the fourth lead screw, and the support frame 23 is driven to slide on the base 1 by rotating the fourth lead screw.

[0041] like Figure 8 As shown, the secondary gripping component 7 includes a second fixed frame 24, which is fixedly mounted on the base 1. A connecting frame 25 slides vertically on the second fixed frame 24, and the connecting frame 25 is located above the positioning component 6. A connecting rod 26 slides horizontally on the connecting frame 25, and a suction frame 27 is fixedly mounted on the connecting rod 26. A second electromagnet 28 is mounted on the suction frame 27. In this embodiment, after the positioning component 6 positions the steel back, the connecting rod 26 slides horizontally on the connecting frame 25, causing the suction frame 27 to move directly above the steel back on the positioning component 6. Then, the connecting frame 25 slides downward along the second fixed frame 24, causing the second electromagnet 28 to contact the steel back. After the second electromagnet 28 is energized, it picks up the steel back. Then, the connecting frame 25 slides upward, separating the steel back from the positioning component 6. The connecting rod 26 slides horizontally along the connecting frame 25, conveying the steel back to the hot press mold and placing the steel back into the mold, completing the secondary gripping.

[0042] It should be noted that, in order to enable the connecting frame 25 to slide on the second fixed frame 24, a fifth lead screw is vertically rotatably mounted on the second fixed frame 24, and a fifth lead screw nut is mounted on the connecting frame 25. The fifth lead screw nut is threadedly connected to the fifth lead screw, and the rotation of the fifth lead screw can drive the connecting frame 25 to slide in the vertical direction. At the same time, in order to make the sliding of the connecting frame 25 more stable, a fifth slide rail is fixedly mounted on the second fixed frame 24. The fifth slide rail is parallel to the fifth lead screw, and a fifth slider is fixedly mounted on the connecting frame 25. The fifth slider is slidably mounted on the fifth slide rail, making the sliding of the connecting frame 25 more stable.

[0043] It should be noted that, in order to allow the connecting rod 26 to slide horizontally on the connecting frame 25, two third pulleys are horizontally rotatably mounted on the connecting frame 25, and a third belt is wound between the two third pulleys. The connecting rod 25 is fixedly connected to the third belt. The rotation of the third pulleys drives the third belt to rotate, thereby causing the connecting rod 25 to slide horizontally between the two third pulleys. In order to make the sliding of the connecting rod more stable, a sixth slide rail is horizontally fixedly mounted on the connecting frame 25, and a sixth slider is fixedly connected to the connecting rod 26. The sixth slider is slidably mounted on the sixth slide rail, making the sliding of the connecting rod 26 more stable and smooth.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
