Description

Technical Field

[0001] This invention relates to the field of metal cutting equipment technology, and more specifically to a laser dismantling device for motor vehicle brake disc brackets equipped with a flip-up positioning structure. Background Technology

[0002] Laser cutting machines are a type of metal cutting equipment with advantages such as high cutting precision, small heat-affected zone, and no mechanical stress damage. Compared with traditional mechanical disassembly, which is prone to component damage and low efficiency, using laser cutting machines to precisely disassemble brake disc brackets can efficiently separate different structures while protecting the integrity of recyclable components, meeting the dual needs of resource recycling and environmental protection. The brake disc bracket is a core load-bearing component in the automotive braking system, used to fix the brake disc and transmit braking torque. Its structural strength and assembly precision directly affect driving safety. Therefore, brake disc brackets are prone to needing replacement after long-term use due to wear, deformation, or failure. In order to achieve resource recycling and reuse and reduce maintenance costs, scrapped and faulty brake disc brackets need to be disassembled to separate recyclable metal components and scrapped structures. Currently, most technologies use laser cutting machines for disassembling brake disc brackets.

[0003] However, the existing technology has the following problems:

[0004] When disassembling the brake disc bracket, existing laser cutting machines require the use of clamps to fix the brake disc bracket. Since most conventional clamps are only suitable for workpieces of the same size, and there are various sizes of brake disc brackets during the brake disc bracket recycling process, the staff needs to be equipped with multiple types of clamps to accommodate different sizes of brake disc brackets, which increases the equipment procurement cost. In addition, changing the clamps also consumes a certain amount of operation time, which affects production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a laser dismantling device for motor vehicle brake disc brackets equipped with a flip-up positioning structure to solve the above-mentioned problems and overcome the defects of the prior art, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The present invention provides a laser dismantling device for a vehicle brake disc bracket equipped with a flip-up positioning structure, comprising: an operating table on which a three-axis automated laser cutting machine is mounted, and a platform on which a clamping assembly is mounted; the clamping assembly includes two mounting boxes, each mounting box containing a set of fixed rods, with telescopic rods slidably sleeved on the fixed rods, and a second spring connecting the telescopic rods and the fixed rods; a clamping block is movably connected to the end of the telescopic rods away from the fixed rods, the clamping block being located outside the mounting boxes; the clamping assembly further includes a driving part for driving the two mounting boxes to approach each other, wherein the clamping blocks on the two mounting boxes can extend and retract with the surface of the brake disc bracket and achieve stable clamping when they approach each other; a locking mechanism is provided on the mounting boxes, the locking mechanism including two locking rods, which can lock multiple telescopic rods; the clamping assembly further includes a flipping mechanism for driving the two mounting boxes to flip.

[0008] Preferably, the drive unit includes two cylinders and two slides. The slides are slidably mounted on the platform, and the cylinders are mounted on the operating table. The output ends of the two cylinders are respectively connected to the two slides with connecting rods.

[0009] Preferably, the end of the telescopic rod away from the fixed rod is provided with a ball head sleeve, and the clamping block is provided with a ball head, and the ball head of the clamping block is movably sleeved with the ball head sleeve of the fixed rod.

[0010] Preferably, the locking mechanism further includes two abutting rods, both of which are connected to the sleeve box. Multiple first springs connect the sleeve box and the mounting box. Both locking rods are slidably connected to the inner wall of the mounting box. A fourth spring connects the locking rods to the mounting box. Two rows of telescopic rods are arranged inside the mounting box. A groove matching one row of telescopic rods is provided on each locking rod. Chamfers are provided at both ends of each locking rod. Two wedges are horizontally slidably connected to the mounting box. A third spring connects the wedges to the mounting box. The two wedges are located between the chamfers at both ends of the two locking rods. The two wedges are located on the movement trajectories of the two abutting rods. When the two abutting rods contact the two wedges, they can drive the two wedges closer together. When the two wedges approach each other, they can drive the two locking rods to approach and abut against the two rows of telescopic rods.

[0011] Preferably, the telescopic rod has an elongated groove, a first connecting rod is hinged in the elongated groove, a push rod is slidably connected in the elongated groove, a second connecting rod is hinged to the push rod, the first and second connecting rods are hinged together, the first and second connecting rods form a V-shaped double-link mechanism, the first connecting rod is located on the movement trajectory of the locking rod, a locking bar is hinged in the elongated groove of the telescopic rod, the push rod can push the locking bar to rotate when it moves, and the locking bar can abut against and lock the ball head of the clamping block after rotation.

[0012] Preferably, there are two flipping mechanisms, each located on a separate carriage. Each flipping mechanism includes a motor, a turntable, and a slotted plate. The motor is mounted on the carriage, the turntable is connected to the output end of the motor, and the slotted plate is mounted on the outer wall of the rotating shaft. The slotted plate has four straight slots and four arc-shaped slots arranged in a circumferential array. A sliding shaft and an arc-shaped block are connected to the turntable. During each rotation of the sliding shaft, it can enter one of the straight slots of the slotted plate and rotate the slotted plate 90 degrees through the straight slot. The arc-shaped block engages with the arc-shaped slot as the sliding shaft disengages from the straight slot of the slotted plate.

[0013] Preferably, the platform is provided with a support assembly, which includes a support base. Two slotted shafts are rotatably mounted on the support base. A rotating rod is connected to each of the two slotted shafts. A support block is connected to the end of the rotating rod away from the slotted shaft.

Two sliding grooves are mirror images of each other on the slotted shaft. The two sliding tongues on the connecting rod are slidably connected to the sliding grooves of the two slotted shafts near the connecting rod. When the two connecting rods are close to each other, the four sliding tongues and the two slotted shafts can drive the two rotating rods to swing downwards.

[0014] Preferably, the platform is provided with a slide assembly, which includes a slide plate and a collection hopper. The slide plate is hinged to the platform, and a light rod is connected to one of the rotating rods. The light rod slides in contact with the bottom of the slide plate.

[0015] Preferably, the slide plate is connected to two vibrating rods, and the platform is connected to two serrated strips. When the two vibrating rods move, they respectively contact the two serrated strips and generate vibration.

[0016] The beneficial effects are:

[0017] 1. This laser dismantling equipment for automotive brake disc brackets, equipped with a flip-up positioning structure, features a clamping component that adapts to various brake disc bracket specifications, significantly improving the equipment's versatility and clamping precision. It also achieves automatic locking of the telescopic rod after clamping, preventing accidental extension or retraction of the rod due to brake disc bracket vibration during laser dismantling and ensuring stable and continuous clamping force. Through the cooperation of the flipping mechanism and clamping component, the brake disc bracket is precisely flipped in a step-by-step manner, with each flip angle being 90 degrees. This meets the laser dismantling requirements of different sides of the brake disc bracket, eliminating the need for manual adjustment of the bracket angle. This not only improves dismantling efficiency but also avoids positioning errors caused by manual adjustment, ensuring consistent dismantling precision across all sides.

[0018] 2. This laser dismantling equipment for motor vehicle brake disc brackets, equipped with a flip-positioning structure, uses a support component to allow two support blocks to mirror each other and form a stable temporary support structure, facilitating the placement of the brake disc bracket by workers. Furthermore, during the clamping of the workpiece, the rotating rod swings downward to detach the support blocks from the brake disc bracket, preventing interference between the support blocks and the brake disc bracket or clamping components during the subsequent flipping of the brake disc bracket, thus ensuring smooth flipping.

[0019] 3. This laser dismantling equipment for motor vehicle brake disc brackets, equipped with a flip-up positioning structure, uses a slide assembly to allow the disassembled parts produced by laser dismantling to fall onto a slide plate. After dismantling, the slide plate automatically tilts upwards, allowing the disassembled parts to slide along the guide of the slide plate into the collection hopper below, achieving centralized collection of the disassembled parts. Furthermore, the slide plate can vibrate to promote the sliding of the disassembled parts above it, while also breaking up any disassembled parts that may be piled up on the slide plate, preventing the disassembled parts from blocking the guide channel of the slide plate, further improving the efficiency and integrity of the disassembled parts collection.

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0042] One embodiment of the present invention is as follows:

[0043] Please see Figure 1 - Figure 9The laser dismantling equipment for automotive brake disc brackets, equipped with a flip-up positioning structure, includes: an operating table 1, on which a three-axis automated laser cutting machine 2 is mounted. The three-axis automated laser cutting machine 2 is existing technology; its specific structure and working principle will not be detailed here. The three-axis automated laser cutting machine 2 can automatically move along three axes to adjust the laser cutting position. A platform 3 is mounted on the operating table 1, and a clamping assembly 4 is installed on the platform 3. The operator places the brake disc bracket above the platform 3, clamps the brake disc bracket using the clamping assembly 4, and then controls the three-axis automated laser cutting machine via a program. The cutting machine 2 performs laser disassembly of the brake disc bracket, completing the laser disassembly operation. The clamping assembly 4 includes two mounting boxes 46, each containing a set of fixing rods 48. A telescopic rod 49 is slidably sleeved on the fixing rods 48, and a second spring 410 connects the telescopic rod 49 to the fixing rods 48. A clamping block 411 is movably connected to the end of the telescopic rod 49 away from the fixing rod 48, and the clamping block 411 is located outside the mounting box 46. The clamping assembly 4 also includes a driving part for driving the two mounting boxes 46 to move closer to each other, with the clamping blocks 411 on the two mounting boxes 46 abutting against each other. The telescopic rod 49 can extend and retract with the surface of the brake disc bracket and achieve stable clamping. The fixed rod 48 serves as the mounting base for the telescopic rod 49, and its axial structure provides a stable sliding guide for the telescopic rod 49. When the second spring 410 is in its natural state, most of the telescopic rod 49 extends out of the mounting box 46. When the two mounting boxes 46 approach each other under the action of the drive unit, the clamping block 411 first contacts the surface of the brake disc bracket. As the mounting boxes 46 continue to approach, the surface of the brake disc bracket generates a reverse pressure on the clamping block 411. This pressure pushes the telescopic rod 49 to retract toward the fixed rod 48, while compressing the second spring 410. 10. Because the second spring 410 has elastic restoring characteristics, it will generate a reverse elastic force on the telescopic rod 49, which will then be transmitted to the surface of the brake disc bracket through the clamping block 411 to form an elastic clamping force. This elastic telescopic structure allows the clamping block 411 to adapt to the irregular contour of the brake disc bracket surface. Multiple clamping blocks 411 can also be independently telescopically adjusted to form effective contact with the surface of the brake disc bracket. Through multi-point elastic clamping, the brake disc bracket is stably positioned, avoiding loosening or displacement of the brake disc bracket during clamping, and providing a precise positioning basis for subsequent laser disassembly.

[0044] Furthermore, the drive unit includes two cylinders 41 and two slides 43. The slides 43 are slidably mounted on the platform 3, and the cylinders 41 are mounted on the operating table 1. The output ends of the two cylinders 41 are respectively connected to the two slides 43 by connecting rods 42. A rotating shaft 44 is rotatably mounted on the slides 43, and a sleeve 45 is connected to the rotating shaft 44. Two mounting boxes 46 are slidably connected to the inner walls of the two sleeves 45. When it is necessary to clamp the brake disc bracket, the two cylinders 41 start synchronously and push the two slides 43 closer to each other through the connecting rods 42. When the slides 43 move, they drive the rotating shaft 44, sleeve 45 and mounting boxes 46 on them to approach the brake disc bracket together until the multiple clamping blocks 411 on the mounting boxes 46 contact the brake disc bracket and clamp it. When it is necessary to release the brake disc bracket, the cylinders 41 retract and pull the slides 43 away through the connecting rods 42, thereby causing the clamping blocks 411 to separate from the brake disc bracket.

[0045] In addition, a ball head sleeve is provided at the end of the telescopic rod 49 away from the fixed rod 48, and a ball head is provided on the clamping block 411. The ball head of the clamping block 411 is movably sleeved with the ball head sleeve of the fixed rod 48. The movable sleeve structure of the ball head sleeve and the ball head constitutes a universal connection mechanism, which allows the clamping block 411 to rotate and adjust in multiple directions around the center of the ball head sleeve. When the clamping block 411 contacts the surface of the brake disc bracket, if the surface of the brake disc bracket is an inclined surface or an arc surface, the clamping block 411 can adjust its own contact angle by the relative rotation of the ball head and the ball head sleeve, ensuring that the surface of the brake disc bracket of the clamping block 411 is completely in contact with it, increasing the contact area between the two, further enhancing the stability of clamping, and enabling the clamping assembly 4 to adapt to brake disc brackets of different shapes and surface morphologies, greatly improving the versatility and clamping accuracy of the equipment.

[0046] In addition, the mounting box 46 is provided with a locking mechanism 5, which includes two locking rods 54, which can lock multiple telescopic rods 49. The locking mechanism 5 also includes two abutting rods 51, which are connected to the sleeve 45. Multiple first springs 47 are connected between the sleeve 45 and the mounting box 46. The two locking rods 54 are slidably connected to the inner wall of the mounting box 46. A fourth spring 55 is connected between the locking rods 54 and the mounting box 46. The telescopic rods 49 inside the mounting box 46 are arranged in two rows. The locking rods 54 have grooves that match a row of telescopic rods 49. Both ends of the locking rods 54 are chamfered. Two wedges 52 are horizontally slidably connected to the mounting box 46. A fourth spring 57 is connected between the wedges 52 and the mounting box 46. Three springs 53 and two wedges 52 are respectively located between the chamfers at both ends of the two locking rods 54. The two wedges 52 are respectively located on the movement trajectory of the two abutting rods 51. When the two abutting rods 51 contact the two wedges 52, they can drive the two wedges 52 to move closer to each other. When the two wedges 52 move closer to each other, they can drive the two locking rods 54 to move closer to and abut against the two rows of telescopic rods 49. In the initial state, the first spring 47 is in a naturally extended state, and the mounting box 46 is in the initial position relative to the sleeve box 45. At this time, the abutting rod 51 is not in contact with the wedge 52. The fourth spring 55 pulls the locking rod 54, so that the groove on the locking rod 54 disengages from the corresponding row of telescopic rods 49. The telescopic rods 49 can extend and retract freely. When the drive unit drives the two mounting boxes 46 to move closer to each other... After clamping the brake disc bracket, the reaction force of the brake disc bracket on the clamping block 411 is transmitted to the mounting box 46 through the telescopic rod 49. The elastic strength of the multiple first springs 47 is greater than that of the multiple second springs 410. Therefore, after the telescopic rods 49 on the two mounting boxes 46 have extended and retracted in conjunction with the surface of the brake disc bracket, as the sleeve 45 continues to apply force, the mounting box 46 begins to slide inward into the sleeve 45, compressing the multiple first springs 47. During the sliding process of the mounting box 46, the two abutting rods 51 on the sleeve 45 approach and contact the two wedges 52 respectively, so that the two abutting rods 51 exert lateral pressure on the two wedges 52 respectively, causing the two wedges 52 to overcome the elastic force of the third spring 53 and move closer to each other. During the process, the wedge 52 gradually inserts itself between the two locking rods 54 along the chamfer at the same end, so that the wedge 52 applies a vertical force to the two locking rods 54 at the same time. This allows the two wedges 52 to move the two locking rods 54 up and down respectively when they approach each other, so that the two locking rods 54 overcome the elastic force of the fourth spring 55 and move closer to the two rows of telescopic rods 49 respectively. Finally, the multiple grooves of the locking rod 54 tightly abut against a row of telescopic rods 49, restricting the telescopic movement of the telescopic rods 49. This achieves the technical effect of automatically locking the telescopic rods 49 after clamping in place, avoiding the accidental extension and retraction of some telescopic rods 49 due to the vibration of the brake disc bracket during laser disassembly, ensuring the stability and continuity of the clamping force, and further improving the disassembly accuracy.

[0047] It is worth noting that the telescopic rod 49 has a long slot, and a first connecting rod 56 is hinged in the long slot. A push rod 58 is slidably connected in the long slot, and a second connecting rod 57 is hinged to the push rod 58. The first connecting rod 56 and the second connecting rod 57 are hinged together, forming a V-shaped double-bar linkage mechanism. The first connecting rod 56 is located on the movement trajectory of the locking rod 54. A locking bar 59 is hinged in the long slot of the telescopic rod 49. When the push rod 58 moves, it can... When the locking bar 59 is rotated, it can abut against and lock the ball head of the clamping block 411. When the locking mechanism 5 is not activated, the hinge joint of the first link 56 and the second link 57 protrudes from the surface of the telescopic rod 49, and the locking bar 59 is not in close contact with the ball head of the clamping block 411. The clamping block 411 can rotate freely to fit the surface of the brake disc bracket. When the locking bar 54 approaches the telescopic rod 49, the locking bar 54 contacts the first link 56 and applies pressure, pushing the first link 56. 6. Rotating around the hinge point, since the first link 56 and the second link 57 are hinged to form a V-shaped structure, the rotation of the first link 56 will drive the second link 57 to move synchronously, thereby pushing the push rod 58 to slide along the long groove of the telescopic rod 49 towards the locking bar 59. During the sliding process, the push rod 58 contacts one end of the locking bar 59 and applies a pushing force, causing the locking bar 59 to rotate around its hinge point. The other end of the locking bar 59 swings towards the ball head of the clamping block 411, and finally comes into close contact with the ball head, restricting movement. The ball head has a degree of freedom of rotation. The locking bar 59 is made of elastic material. After the clamp is released, the locking bar 59 resets through its own elasticity, which simultaneously drives the first link 56, the second link 57 and the push rod 58 to reset. This allows the locking bar 59 to simultaneously fix the rotation angle of the clamping block 411 while the locking rod 54 fixes the telescopic rod 49 in its telescopic state. This ensures that the clamping block 411 and the surface of the brake disc bracket remain in contact and prevents the clamping block 411 from shifting due to vibration during laser disassembly.

[0048] It is worth noting that the clamping assembly 4 also includes a flipping mechanism 6 for rotating the two mounting boxes 46. There are two flipping mechanisms 6, which are respectively located on the two slides 43. The flipping mechanism 6 includes a motor 61, a turntable 62, and a slotted plate 63. The motor 61 is mounted on the slide 43, the turntable 62 is connected to the output end of the motor 61, and the slotted plate 63 is mounted on the outer wall of the rotating shaft 44. The slotted plate 63 has four straight slots and four arc-shaped slots arranged in a circumferential array. The turntable 62 is connected to the sliding shaft 64 and the arc-shaped block 65. During each rotation of the sliding shaft 64, it can enter one of the straight slots of the slotted plate 63 and rotate the slotted plate 63 through the straight slot. The arc-shaped block 65 engages with the arc-shaped groove as the sliding shaft 64 disengages from the straight groove of the slotted plate 63. The laser disassembly of the brake disc bracket involves four laser disassemblies: top, two sides, and bottom. Therefore, a total of three 90-degree rotations are required to achieve four-sided disassembly. When the brake disc bracket needs to be rotated, the two motors 61, controlled by the same control system, rotate synchronously. After the motors 61 start, they drive the turntable 62 to rotate one revolution. The sliding shaft 64 and arc-shaped block 65 on the turntable 62 rotate synchronously with the turntable 62. When the sliding shaft 64 rotates to the entrance of the straight groove of the slotted plate 63, as the turntable 62 continues to rotate, the sliding shaft 64... The sliding shaft 64 enters the straight groove and contacts its side wall. The circular motion of the sliding shaft 64 is converted into rotational power for the slotted disk 63 through the force exerted by the side wall, driving both the slotted disk 63 and the rotating shaft 44 to rotate. When the sliding shaft 64 rotates one full turn and disengages from the current straight groove, the slotted disk 63 and the rotating shaft 44 rotate exactly ninety degrees. At this moment, the arc-shaped block 65 on the turntable 62 rotates synchronously to the position of the arc-shaped groove on the slotted disk 63 and embeds itself within it. The mating surfaces of the arc-shaped block 65 and the arc-shaped groove abut against each other, restricting the rotation of the slotted disk 63 and achieving positioning and locking. The circular array design of four straight grooves and four arc-shaped grooves ensures that the slotted disk 63 rotates precisely for every full turn of the turntable 62 driven by the motor 61. The brake disc bracket is positioned at 90 degrees and via the arc block 65, thereby causing the rotating shaft 44, sleeve 45, mounting box 46, and clamped brake disc bracket to rotate synchronously by 90 degrees. After three rotations, the four sides of the brake disc bracket are laser disassembled. One more rotation will reset the clamping component 4 to its initial state. Through the cooperation of the rotation mechanism 6 and the clamping component 4, the brake disc bracket is precisely rotated in a step-by-step manner, and each rotation angle is 90 degrees, which meets the laser disassembly requirements of different sides of the brake disc bracket. There is no need to manually adjust the angle of the brake disc bracket, which not only improves the disassembly efficiency but also avoids the positioning error caused by manual adjustment, ensuring the consistency of disassembly accuracy on each side.

[0049] Based on the above embodiments, another embodiment of the present invention is as follows:

[0050] Please see Figure 1 , Figure 10 , Figure 11A support assembly 7 is provided on the platform 3. The support assembly 7 includes a support 71, on which two slotted shafts 72 are rotatably mounted. A rotating rod 73 is connected to each of the two slotted shafts 72. A support block 74 is connected to the end of the rotating rod 73 away from the slotted shaft 72. The two support blocks 74 are mirror images of each other and are in contact. Two sliding tongues 76 are installed on the connecting rod 42. Two sliding grooves 75 are mirror images of each other on the slotted shaft 72. The two sliding tongues 76 on the connecting rod 42 are slidably connected to the sliding grooves 75 of the two slotted shafts 72 near the connecting rod 42. The sliding grooves 75 are divided into two... A straight groove and an arc-shaped groove are connected between the two straight grooves. When the sliding tongue 76 slides along the straight groove, it does not drive the groove shaft 72 to rotate. When the sliding tongue 76 slides along the arc-shaped groove, it can apply a force to the groove shaft 72 and drive the groove shaft 72 to rotate. When the two connecting rods 42 are close to each other, they can drive the two rotating rods 73 to swing downward through the cooperation of the four sliding tongues 76 and the two groove shafts 72. When the clamping assembly 4 is not activated, the two support blocks 74 are mirror-fitted to form a stable temporary support structure, and the operator can directly and stably place the brake disc bracket on the two support blocks 74. The initial positioning of the brake disc bracket is achieved. After the clamping assembly 4 is activated, the two cylinders 41 drive the corresponding connecting rods 42 to move closer to each other synchronously. The two sliding tongues 76 on the connecting rods 42 also move synchronously. The sliding tongues 76 first slide along the straight groove on the groove shaft 72. During this process, they only move in a straight line and do not drive the groove shaft 72 to rotate. The support block 74 maintains the support state for the brake disc bracket, ensuring that the clamping block 411 of the clamping assembly 4 can accurately approach and contact the brake disc bracket. As the connecting rods 42 continue to approach, the sliding tongues 76 slide into the arc groove. At this time, The clamping assembly 4 has formed a stable clamp on the brake disc bracket. The inclined structure of the arc groove causes the sliding tongue 76 to generate a lateral thrust on the groove wall of the groove shaft 72 when it moves, thereby driving the two groove shafts 72 to rotate synchronously around the support 71. When the groove shafts 72 rotate, they drive the connected rotating rod 73 to swing downward. The rotating rod 73 then pulls the support block 74 away from the bottom of the brake disc bracket until the support block 74 is completely detached from the brake disc bracket. This avoids interference between the support block 74 and the brake disc bracket or the clamping assembly 4 during the subsequent rotation of the brake disc bracket, ensuring that the rotation action is carried out smoothly.

[0051] Based on the above embodiments, another embodiment of the present invention is as follows:

[0052] Please see Figure 1 , Figure 12 , Figure 13A slide assembly 8 is provided on the platform 3. The slide assembly 8 includes a slide plate 81 and a collection hopper 85. The slide plate 81 is hinged to the platform 3. A guide rod 82 is connected to one of the rotating rods 73. The guide rod 82 slides in contact with the bottom of the slide plate 81. When the guide rod 82 moves upward, it can support and drive the slide plate 81 to swing upward. The collection hopper 85 is installed on the platform 3 and is located below the slide plate 81. When the clamping assembly 4 is not activated and the rotating rod 73 is not swinging downward, the guide rod 82 on the rotating rod 73 contacts the bottom of the slide plate 81 and forms a stable support, keeping the slide plate 81 in an inclined state. At this time, the upper end of the slide plate 81 is close to the brake disc bracket placement area, and the lower end faces the collection hopper 85. When the clamping assembly 4 is activated and the rotating rod 73 swings downward, the guide rod 82 moves synchronously with the rotating rod 73. As it moves downward, the supporting force on the slide plate 81 gradually disappears. Under its own gravity, the slide plate 81 swings downward and eventually reaches a near-horizontal state, disengaging from the flipping path of the brake disc bracket. After the brake disc bracket disassembly is completed, the clamping assembly 4 releases the brake disc bracket, and at the same time, the rotating rod 73 swings upward to reset. The light rod 82 moves upward and pushes the bottom of the slide plate 81 again, causing the slide plate 81 to swing upward again to an inclined state. During laser disassembly, some of the disassembled parts that have been cut off will fall directly onto the slide plate 81. After the brake disc bracket is completely disassembled, the disassembled parts that have been released from the clamp will also fall onto the slide plate 81. With the help of the tilt angle of the slide plate 81 and its own gravity, the disassembled parts slide along the guide of the slide plate 81 into the collection hopper 85 below, realizing the centralized collection of the disassembled parts.

[0053] It is worth mentioning that two vibrating rods 83 are connected to the slide plate 81, and two serrated strips 84 are connected to the platform 3. When the two vibrating rods 83 move, they contact the two serrated strips 84 respectively and generate vibration. When the slide plate 81 swings upward under the drive of the light rod 82, or swings downward under the action of gravity, the slide plate 81 will drive the vibrating rods 83 on both sides to move synchronously. During the movement of the vibrating rods 83, they contact, collide and slide with the serrated strips 84. The serrated structure of the serrated strips 84 causes the contact point between the two to change continuously, forming an intermittent impact force, which in turn causes the slide plate 81 to vibrate. The vibration of the slide plate 81 can promote the sliding of the disassembled parts above it, and at the same time disperse the disassembled parts that may be piled up on the slide plate 81, preventing the disassembled parts from blocking the guide channel of the slide plate 81, and further improving the efficiency and integrity of disassembled parts collection.
