Description

Technical Field

[0001] This invention relates to the field of disc brake assembly technology, specifically to a robot for assembling disc brake discs for new energy electric vehicles. Background Technology

[0002] Currently, in the wheel hub manufacturing process, disc brake discs need to be installed on the wheel hub to ensure they can cooperate with the braking components and thus achieve braking of the wheel hub. Existing assembly methods typically use screws to fix the disc brake disc to the wheel hub. The specific process is as follows: the operator places the wheel hub on a flat surface, then places the disc brake disc on top of the wheel hub, ensuring the disc brake disc aligns with the threaded holes on the wheel hub. Next, the disc brake disc is securely fixed to the wheel hub with bolts. Finally, the installation is checked to ensure it meets specifications; if not, it is corrected; once it meets specifications, a marker is used to mark the installation status.

[0003] With the popularization of intelligent manufacturing technology, China has published a patent application (application number 201910257963.2) introducing a "fully automatic motorcycle and electric vehicle disc brake disc assembly machine." This device includes a rotary worktable, a hub hole detection and positioning mechanism, and a disc brake disc positioning and gripping mechanism. This system can effectively save labor costs and automatically complete the disc brake disc assembly. However, during the assembly process where the disc brake disc is fixed with bolts, there is a risk of deformation. A deformed disc brake disc will affect braking performance and reduce product quality. Currently, after assembly, this automated device cannot replace manual inspection of the disc brake disc, nor can it complete the installation status marking work, thus restricting the continuity and efficiency of the assembly process. Summary of the Invention

[0004] The purpose of this invention is to provide a robot for assembling disc brake discs for new energy electric vehicles. This invention solves the problem that existing devices require manual inspection and marking, which affects assembly efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a robot for assembling disc brake discs for new energy electric vehicles, comprising:

[0006] A rotating worktable drives the wheel hub to rotate intermittently at a preset angle, and a robotic arm and an automatic screw assembly machine are arranged sequentially around its circumference.

[0007] A robotic arm is used to grasp the disc brake disc and precisely position it onto the mounting surface of the wheel hub;

[0008] Automatic screw assembly machine, used to lock disc brake discs and wheel hubs;

[0009] The marking mechanism includes a support plate and several sets of second round rods. Each set of second round rods has a conductive plate at its upper end. The conductive plate is electrically connected to a miniature electric telescopic rod via a wire. The output shaft of the miniature electric telescopic rod abuts against a rotatable pen holder via a third round rod, which is used to hold a marker pen. When one end of the second round rod abuts against the disc brake, the other end presses against the conductive plate. If the disc brake is deformed, causing any conductive plate to lose connection with the wire, the miniature electric telescopic rod does not work. If the disc brake is not deformed, all conductive plates are connected to the wire, the miniature electric telescopic rod works, and the pen holder rotates to drive the marker pen to mark.

[0010] Preferably, a first support frame is installed on the upper surface of the automatic screw assembly machine, and a first electric telescopic rod is installed on the upper surface of the first support frame. The first electric telescopic rod controls the lifting and lowering of the automatic screw assembly machine.

[0011] Preferably, a plurality of positioning blocks are evenly installed on the upper surface of the rotating worktable.

[0012] Preferably, the marking mechanism includes a second support frame, a second electric telescopic rod is mounted on the upper end face of the second support frame, the output shaft of the second electric telescopic rod passes through the second support frame and is fixedly mounted with a first round rod, and the lower end face of the first round rod is fixedly connected to the support plate.

[0013] Preferably, the outer wall of the support plate has a plurality of openings evenly distributed, the inner wall of the openings is rotatably connected to the pen holder, the outer wall of the pen holder is fitted with an elastic rope, and the side of the elastic rope away from the pen holder is mounted on the support plate.

[0014] Preferably, a plurality of fixing blocks are evenly installed on the upper surface of the support plate, and the fixing blocks are fixedly connected to the miniature electric telescopic rod.

[0015] Preferably, a support rod is installed on the upper end face of the conductive sheet, and a spring is installed on the upper end face of the conductive sheet away from the pen holder. The spring is installed on the support rod on the side away from the conductive sheet.

[0016] Preferably, the upper end faces of the two support rods are respectively equipped with a first terminal and a second terminal.

[0017] Preferably, the conductive sheet is Z-shaped, and the upper end face of the conductive sheet away from the spring abuts against the rotating plate.

[0018] Preferably, conductive blocks are installed on the upper end face of the second round rod near the pen holder, and the conductive blocks are rotatably connected to the rotating plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] I. This invention features a marking mechanism. When the edge of the disc brake disc is raised, the conductive block moves upward a greater distance. After the rotating plate rotates a certain angle, it detaches from the conductive plate. At this point, even if the second electric telescopic rod extends to the specified length, the circuit remains disconnected. When the edge of the disc brake disc is bent downward, the conductive block moves upward a less distance, preventing it from contacting the slider. Again, even if the second electric telescopic rod extends to the specified length, the circuit remains disconnected. This mechanism can replace manual inspection of the disc brake disc installation. If the disc brake disc deformation is within the error range, the rotating plate will connect the conductive plate and the slider, controlling the micro electric telescopic rod to rotate the pen holder. The marker pen inside the pen holder marks the disc brake disc, improving assembly efficiency. The pen holder ensures that when it rotates to mark the disc brake disc, the three lines follow the same trajectory, resulting in both aesthetic appeal and practicality. Even if one mark disappears due to wear or other reasons after use, the original mark position can still be deduced from the other two marks, allowing for the determination of whether the disc brake disc is loose.

[0030] To better understand the purpose, technical solution, and advantages of this application, the application is described and illustrated below in conjunction with the accompanying drawings and embodiments.

[0031] Please see Figures 1 to 9 This invention provides a technical solution: a robot for assembling disc brake discs in new energy electric vehicles, comprising:

[0032] The rotating worktable 3 drives the hub 8 to rotate intermittently at a preset angle, and the circumference of the worktable is provided with a robotic arm 1 and an automatic screw assembly machine 202.

[0033] Robotic arm 1 is used to grab disc brake disc 9 and precisely position it to the mounting surface of wheel hub 8;

[0034] Automatic screw assembly machine 202 is used to lock the disc brake disc 9 and the wheel hub 8;

[0035] The marking mechanism includes a support plate 7 and several sets of second round rods 21. Each set of second round rods 21 has a conductive sheet 13 at its upper end. The conductive sheet 13 is electrically connected to a miniature electric telescopic rod 17 via a wire 20. The output shaft of the miniature electric telescopic rod 17 abuts against a rotatable pen holder 15 via a third round rod 22, which is used to hold a marker pen. When one end of the second round rod 21 abuts against the disc brake 9, the other end presses against the conductive sheet 13. If the disc brake 9 is deformed, causing any conductive sheet 13 to be disconnected from the wire 20, the miniature electric telescopic rod 17 does not work. If the disc brake 9 is not deformed, all conductive sheets 13 are connected to the wire 20, the miniature electric telescopic rod 17 works, and the pen holder 15 rotates to drive the marker pen to mark.

[0036] In this embodiment, the rotary worktable 3, the robotic arm 1, and the automatic screw assembly machine 202 are all existing technologies.

[0037] Furthermore, such as Figure 1As shown, the automatic screw assembly machine 202 is equipped with a first support frame 2 on its upper end face, and a first electric telescopic rod 201 is installed on the upper end face of the first support frame 2. The first electric telescopic rod 201 controls the automatic screw assembly machine 202 to rise and fall; the first electric telescopic rod 201 drives it to move up and down to assemble the bolts onto the disc brake disc 9 and the wheel hub 8.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, several positioning blocks 10 are evenly installed on the upper surface of the rotary worktable 3; the positioning blocks 10 can position the wheel hub 8.

[0039] Furthermore, such as Figure 2 As shown, the marking mechanism includes a second support frame 4, a second electric telescopic rod 5 is mounted on the upper end face of the second support frame 4, and a first round rod 6 is fixedly mounted through the output shaft of the second electric telescopic rod 5 through the second support frame 4. The lower end face of the first round rod 6 is fixedly connected to the support plate 7. When the second electric telescopic rod 5 is working, it drives the support plate 7 to move through the first round rod 6.

[0040] Furthermore, such as Figure 3 As shown, the outer wall of the support plate 7 is evenly provided with a plurality of openings 19. The inner wall of the opening 19 is rotatably connected to the pen holder 15. An elastic rope 14 is installed on the outer wall of the pen holder 15. The side of the elastic rope 14 away from the pen holder 15 is installed on the support plate 7. The elastic rope 14 is used to drive the pen holder 15 to reset.

[0041] Furthermore, such as Figure 3 and Figure 6 As shown, several fixing blocks 16 are evenly installed on the upper surface of the support plate 7, and the fixing blocks 16 are fixedly connected to the miniature electric telescopic rod 17.

[0042] Furthermore, such as Figure 3 As shown, a support rod 12 is installed on the upper end face of the conductive sheet 13, and a spring 26 is installed on the upper end face of the conductive sheet 13 away from the pen holder 15. The spring 26 is installed on the support rod 12 on the side away from the conductive sheet 13; the spring 26 drives the conductive sheet 13 to reset.

[0043] Furthermore, such as Figure 3 As shown, the upper surfaces of the two support rods 12 are respectively equipped with a first terminal 11 and a second terminal 18; the first terminal 11 and the second terminal 18 are used to connect external wires, and the support rods 12 are made of insulating material.

[0044] Furthermore, such as Figure 5 and Figure 6As shown, the conductive sheet 13 is Z-shaped. The upper end face of the conductive sheet 13 away from the spring 26 abuts against the rotating plate 25. The upper end face of the second round rod 21 near the pen holder 15 is equipped with conductive blocks 24. The conductive blocks 24 are rotatably connected to the rotating plate 25. The two ends of the wire 20 are respectively equipped with sliders 23. The sliders 23 are slidably connected to the support rod 12, and the sliders 23 do not contact the spring 26. The sliders 23 and the rotating plate 25 are made of conductive materials. In this embodiment, the circuit formed by the conductive sheet 13 and the wire 20 is a control circuit with a voltage of 12V.

[0045] In this embodiment, as Figure 7 As shown, when the disc brake disc 9 deforms within the specified range, the second electric telescopic rod 5 descends, the second round rod 21 abuts against the disc brake disc 9, the second round rod 21 drives the conductive block 24 to rise, the conductive block 24 drives the rotating plate 25 to rise, and the rotating plate 25 continues to abut against the conductive sheet 13 while rotating. When the conductive block 24 abuts against the slider 23, the circuit is connected, and at this time the second electric telescopic rod 5 also extends to the specified length.

[0046] like Figure 8 As shown, when the edge of the disc brake disc 9 tilts upward, the second electric telescopic rod 5 descends, the second round rod 21 abuts against the disc brake disc 9, the second round rod 21 drives the conductive block 24 to rise, the conductive block 24 drives the rotating plate 25 to rise, and the rotating plate 25 continues to abut against the conductive sheet 13 while rotating. Since the disc brake disc 9 tilts upward, the conductive block 24 moves upward a greater distance. After the rotating plate 25 rotates a certain angle, it will detach from the conductive sheet 13. At this time, even if the second electric telescopic rod 5 extends to the specified length, the circuit is not connected.

[0047] like Figure 9 As shown, when the edge of the disc brake disc 9 bends downward, the second electric telescopic rod 5 descends, the second round rod 21 abuts against the disc brake disc 9, the second round rod 21 drives the conductive block 24 to rise, the conductive block 24 drives the rotating plate 25 to rise, and the rotating plate 25 continues to abut against the conductive plate 13 while rotating. Since the disc brake disc 9 bends downward, the upward movement distance of the conductive block 24 is reduced, and the conductive block 24 cannot abut against the slider 23. At this time, even if the second electric telescopic rod 5 extends to the specified length, the circuit is not connected.

[0048] Working principle: Step 1: The operator places the wheel hub 8 on the rotating worktable 3 and makes it cooperate with the positioning block 10. At this time, the rotating worktable 3 rotates intermittently at a certain angle. At this time, the robotic arm 1 picks up the external disc brake disc 9 and places it on the wheel hub 8. Since the wheel hub 8 is limited by the positioning block 10, the disc brake disc 9 and the wheel hub 8 are positioned.

[0049] Step 2: The rotating worktable 3 rotates again, causing the wheel hub 8 and disc brake disc 9 to move below the automatic screw assembly machine 202. At this time, the first electric telescopic rod 201 descends, causing the automatic screw assembly machine 202 to descend as well. The automatic screw assembly machine 202 then uses bolts to assemble the disc brake disc 9 and wheel hub 8.

[0050] Step 3: The rotating worktable 3 rotates again, causing the assembled wheel hub 8 to rotate to the bottom of the second support frame 4. At this time, the second electric telescopic rod 5 extends, causing the first round rod 6 to descend. The first round rod 6 causes the support plate 7 to descend. The support plate 7 causes the support rod 12 and the second round rod 21 to descend. At this time, the spring 26 and the second round rod 21 below the conductive block 24 abut against the disc brake disc 9 and slide upward. The second round rod 21 below the spring 26 will squeeze the conductive sheet 13, and the conductive sheet 13 will squeeze the spring 26.

[0051] At this time, the second round rod 21 located below the conductive block 24 slides upward, and the conductive block 24 drives the rotating plate 25 to move. The rotating plate 25 slides on the conductive sheet 13 and continues to contact it. If the deformation of the disc brake disc 9 is within the allowable error range, the upper part of the conductive block 24 will contact the slider 23. At this time, the circuit is connected, the micro electric telescopic rod 17 extends, and drives the third round rod 22 to move. The third round rod 22 squeezes the pen holder 15, and the pen holder 15 rotates in the opening 19 and stretches the elastic rope 14. At this time, the marker pen in the pen holder 15 marks the surface of the disc brake disc 9 until the marker pen abuts against the bolt. At this time, the marking is completed, and the three marking tracks are the same, which is not only beautiful but also more practical (for example, after use, if any one of the markings on the disc brake disc 9 falls off, the other track can still be deduced from the other two tracks, so as to determine whether it is loose).

[0052] Step 4: If the disc brake disc 9 is deformed at this time (the edge is raised or bent downward), the rotating plate 25 will detach from the conductive sheet 13 or the conductive block 24 will not contact the slider 23, so that the circuit is not connected and the marker will not complete the marking. When the rotating worktable 3 continues to rotate, the operator can remove it and see the assembly status, which is convenient for subsequent correction.
