Description

Technical Field

[0001] The present invention relates to the technical field of brake pad processing, and particularly to a laser marking machine for brake pad processing. Background Art

[0002] Automobile brake pads mainly consist of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate needs to be painted during the production process to prevent rust. To ensure the painting quality, a furnace temperature tracker is usually used to monitor the temperature distribution during the painting process. In the manufacturing process of brake pads, drilling operations also need to be performed on them, and the inner arc and outer arc are ground. After grinding, the dust and debris on the brake pads must be cleaned. When the cleaning work is completed, laser marking is carried out on the outer arc of the brake pads. However, the currently commonly used marking method is to manually place each brake pad under the laser marking head of the laser marking machine one by one, which has obvious low efficiency problems.

[0006] As a further improvement of the present invention, the pushing mechanism includes a second arc-shaped block arranged in the arc-shaped groove, an installation groove is opened on one side of the arc-shaped groove close to the second arc-shaped block, a second electric telescopic rod is installed in the installation groove, and the telescopic end of the second electric telescopic rod is fixedly connected to the second arc-shaped block.

[0007] As a further improvement of the present invention, the driving mechanism includes a fixing plate fixedly connected to one side of the support block. A stepping motor is installed on the support block. The output shaft end of the stepping motor penetrates through the fixing plate and is fixedly connected with a driving gear, and the driving gear meshes with a driven gear.

[0008] As a further improvement of the present invention, the first belt conveyor is supported by two first fixing blocks, and the second belt conveyor is supported by two second fixing blocks.

[0009] As a further improvement of the present invention, both sides of the upper end of the first belt conveyor are fixedly connected with first guiding blocks, and both sides of the upper end of the second belt conveyor are fixedly connected with second guiding blocks.

[0010] As a further improvement of the present invention, the first extension block is fixedly connected to one side of the first belt conveyor. Two first limiting blocks are fixedly connected to the upper end of the first extension block. The second extension block is fixedly connected to one side of the second belt conveyor. Two second limiting blocks are fixedly connected to the upper end of the second extension block.

[0011] As a further improvement of the present invention, conical blocks are fixedly connected to the lower ends of both the first extension block and the second extension block.

[0012] As a further improvement of the present invention, a mounting plate is fixedly connected to the side of the first belt conveyor away from the first extension block. A first electric telescopic rod is fixedly connected to the upper end of the mounting plate. The telescopic end of the first electric telescopic rod is fixedly connected with a first arc-shaped block.

[0013] As a further improvement of the present invention, telescopic grooves are respectively formed in the upper end of the turntable in a plurality of arc-shaped grooves.

[0015] Advantages of the present invention:

[0016] Through the design of four independent arc-shaped grooves of the turntable and the precise control of the stepping motor, the present invention realizes the automated operation in the process of brake pad marking.

[0017] The device adopts a telescopic column fixing mechanism with a conical block and a spring in linkage, which automatically fixes and releases the brake pads during the rotation of the turntable. When the arc-shaped groove rotates to the position of the belt conveyor, the conical block squeezes the moving plate to retract the telescopic column, facilitating the entry and exit of the brake pads; while at the marking station, the spring rebounds to automatically extend the telescopic column to fix the brake pads, effectively preventing displacement caused by centrifugal force and improving the stability and reliability of the equipment operation.

[0018] By optimizing the connection structure between the belt conveyor and the turntable, the present invention realizes the automatic control of material transportation. The first guiding block and the second guiding block ensure the accurate entry of the brake pads into the arc-shaped groove, and the first limiting block and the second limiting block prevent deviation and jamming. Cooperating with the first electric telescopic rod and the second electric telescopic rod to complete automatic loading and unloading, a complete continuous production process is formed, reducing the manual intervention link and improving the production efficiency and safety.

[0019] The present invention improves the marking accuracy and production efficiency of the brake pads, reduces the manual labor intensity, and enhances the stability and safety of the production process. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Figures 1 - 7, A laser marking machine for brake pad processing, including a base 1, the base 1 provides basic support for the entire device. At the upper end of the base 1, there is a fixed connection with a support block 2. At the upper end of the support block 2, there is a fixed connection with a support column 18. A driven gear 26 is sleeved on the support column 18. At the upper end of the driven gear 26, there is a fixed connection with a turntable 5 that is rotatably sleeved on the support column 18. The turntable 5 is used to carry the brake pads to be marked. The support column 18 serves as the rotation center of the turntable 5. At the upper end of the turntable 5, there is a fixed connection with a rotating block 6 that is sleeved on the support column 18. Four arc-shaped grooves 15 are opened on the rotating block 6. The rotating block 6 is divided into four independent workstations through the arc-shaped grooves 15. At the upper end of the turntable 5, within multiple arc-shaped grooves 15, there are opened telescopic grooves 19. In each telescopic groove 19, there is a telescopic column 20. The telescopic column 20 fixes the brake pad in the extended state. Below the turntable 5, there are also multiple telescopic mechanisms for driving the telescopic column 20 to move. The telescopic mechanism is used to control the expansion and contraction of the telescopic column 20, and thus fix and limit the brake pad. The telescopic mechanism includes a support frame 23 fixedly connected to the lower end of the turntable 5. A moving plate 25 moves up and down within the support frame 23. The lower end of the telescopic column 20 passes through the telescopic groove 19 and is fixedly connected to the upper end of the moving plate 25. At the lower end of the moving plate 25, there are two fixed connections with springs 24. The moving plate 25 realizes the retraction of the telescopic column 20 by compressing the springs 24, and realizes the extension of the telescopic column 20 through the rebound of the springs 24. The other ends of the two springs 24 are fixedly connected to the inner bottom of the support frame 23.

[0030] In each arc-shaped groove 15, there is a pushing mechanism. The pushing mechanism is used to push the brake pads after marking out of the arc-shaped groove 15 to the belt conveyor. The pushing mechanism includes a second arc-shaped block 17 arranged in the arc-shaped groove 15. On one side of the arc-shaped groove 15 close to the second arc-shaped block 17, there is an installation groove 30. A second electric telescopic rod 28 is installed in the installation groove 30. The installation groove 30 provides an installation space for the second electric telescopic rod 28. The telescopic end of the second electric telescopic rod 28 is fixedly connected to the second arc-shaped block 17. The second arc-shaped block 17 is driven to move linearly by the second electric telescopic rod 28. At the upper end of the support column 18, there is a fixed connection with a circular plate 16. At the upper end of the circular plate 16, there is a fixed connection with a marking device 7. The circular plate 16 provides a stable installation platform for the marking device 7. On the support block 2, there is a driving mechanism connected to the driven gear 26. The driving mechanism controls the rotation of the turntable 5 through gear meshing. The driving mechanism includes a fixed plate 4 fixedly connected to one side of the support block 2. A stepping motor 3 is installed on the support block 2. The stepping motor 3 can accurately control the rotation angle and rotation speed. The output shaft end of the stepping motor 3 passes through the fixed plate 4 and is fixedly connected to a driving gear 27. The driving gear 27 meshes with the driven gear 26. The power of the stepping motor 3 is transmitted to the driven gear 26 through the driving gear 27, and drives the turntable 5 to rotate through the rotation of the driven gear 26.

[0031] On one side of the rotating block 6, there is a first belt conveyor 8 which is used to convey the brake pads to be marked. On one side of the first belt conveyor 8, there is a second belt conveyor 9 which is used to output the marked brake pads. On both sides of the upper end of the first belt conveyor 8, there are first guiding blocks 13 fixedly connected. The first guiding blocks 13 ensure that the brake pads enter the arc-shaped groove 15 along the center line. On both sides of the upper end of the second belt conveyor 9, there are second guiding blocks 14 fixedly connected. The second guiding blocks 14 guide the finished products into the subsequent processes. The first belt conveyor 8 is supported by two first fixing blocks 31, and the second belt conveyor 9 is supported by two second fixing blocks 32. The first belt conveyor 8 and the second belt conveyor 9 are respectively in contact with the turntable 5 through the first extension block 22 and the second extension block 33 to realize the connection between the first belt conveyor 8 and the second belt conveyor 9 and the turntable 5. The first extension block 22 is fixedly connected to one side of the first belt conveyor 8. On the side of the first belt conveyor 8 away from the first extension block 22, there is an installation plate 10 fixedly connected. On the upper end of the installation plate 10, there is a first electric telescopic rod 11 which provides the pushing force for feeding. The telescopic end of the first electric telescopic rod 11 is fixedly connected with a first arc-shaped block 12. On the upper end of the first extension block 22, there are two first limiting blocks 21 which are used to guide the brake pads into the arc-shaped groove 15. The second extension block 33 is fixedly connected to one side of the second belt conveyor 9. On the upper end of the second extension block 33, there are two second limiting blocks 34 which are used to guide the brake pads out of the arc-shaped groove 15. At the lower ends of the first extension block 22 and the second extension block 33, there are conical blocks 29 which squeeze the moving plate 25 when the turntable 5 rotates to a specific position.

[0032] When the present invention is in use, first start the first belt conveyor 8, the second belt conveyor 9 and the stepping motor 3. The first belt conveyor 8 will transport the brake pads that have not been marked to the position of the first arc block 12. Subsequently, start the first electric telescopic rod 11 to drive the first arc block 12 to push the brake pads from the first belt conveyor 8 into the arc groove 15, and start the marking device 7 to mark the brake pads. During the movement, the two first guiding blocks 13 will guide the brake pads into the correct movement track. At the same time, the two first limiting blocks 21 and the first extension block 22 will also guide and assist the brake pads to smoothly push them into the arc groove 15. Subsequently, the intermittent rotation of the stepping motor 3 will be transmitted to the driven gear 26 through the driving gear 27, and the driven gear 26 will drive the turntable 5 to rotate by 90 degrees, thereby driving the brake pads to rotate for marking the next graphic. After four complete marking processes, it will rotate in front of the second belt conveyor 9. Subsequently, the second electric telescopic rod 28 is driven to drive the second arc block 17 to move, push the marked brake pads away from the arc groove 15, and move to the second belt conveyor 9 under the guiding and assisting of the two second limiting blocks 34 and the second extension block 33, and continue to enter the correct movement track through the two second guiding blocks 14, and then enter the subsequent process.

[0033] During the entire marking process, the brake pads need to be briefly fixed and limited to prevent them from being affected by the centrifugal force generated by the rotation of the turntable 5. Therefore, the cooperation of the telescopic machine, the telescopic column 20 and the conical block 29 is required. When the turntable 5 drives the corresponding arc groove 15 to rotate to the position corresponding to the first belt conveyor 8 and the second belt conveyor 9, the conical block 29 located below the first extension block 22 and the second extension block 33 will insert into the intermittent groove between the corresponding moving plate 25 and the turntable 5. Due to the shape of the conical block 29, it will gradually squeeze the corresponding moving plate 25 to move downward and squeeze the corresponding spring 24. Due to the downward movement of the moving plate 25, it will drive the telescopic column 20 to retract into the telescopic groove 19, so that the brake pads can smoothly enter or exit the corresponding arc groove 15. When the arc groove 15 rotates and is no longer corresponding to the first belt conveyor 8 and the second belt conveyor 9, due to the loss of the extrusion of the conical block 29, the moving plate 25 will drive the telescopic column 20 to extend out of the telescopic groove 19 again under the resilience of the spring 24 and insert into the middle hole of the brake pads to fix and limit the brake pads.

[0034] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
