Description

Technical Field

[0001] The present invention relates to the technical field of vehicle mounting devices, and in particular to a brake pedal sub-assembly system. Background Art

[0002] When sub-assembling the traditional operation brake pedal, it is necessary to sub-assemble the accelerator pedal onto the brake pedal and assemble two switch bases on the pedal bracket at the same time. The existing method is as follows: manually sub-assemble the accelerator pedal, assemble the accelerator pedal onto the brake pedal with two bolts, and need to press the switch base for assembly with fingers. The existing sub-assembly method has the following problems:

[0003] 1. Long-term pressing of the switch base causes pain in the worker's fingers. In the ergonomic evaluation, the employee complaint degree is high and it is listed as a project that needs to be improved;

[0004] 2. Efficiency: The efficiency of traditional manual assembly operations is relatively low;

[0005] 3. Quality: The quality of manual assembly operations is unstable, and problems such as incomplete sub-assembly, abnormal actuation of the accelerator pedal, and poor switch contact are likely to occur.

[0006] 4. Safety: Manually sub-assembling the switch base and pressing two switch bases (differentiated parts) onto the pedal bracket are likely to cause incorrect assembly of the switch base, resulting in poor signals of the brake pedal and accelerator pedal and accidents. Similarly, incomplete assembly will also pose a hidden danger of poor signal contact.

[0053] The following further illustrates the detailed implementation manners of the present invention with reference to the drawings.

[0054] It is easy to understand that according to the technical solution of the present invention, under the condition of not changing the essence of the present invention, those of ordinary skill in the art can adopt various structural manners and implementation manners that can be mutually replaced. Therefore, the following detailed implementation manners and the drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the invention.

[0055] In this specification, orientation terms such as up, down, left, right, front, back, front side, back side, top, and bottom, which are mentioned or may be mentioned, are defined relative to the structures shown in the respective drawings. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0056] In some embodiments of the present invention, as Figure 1 and Figure 6 shown, the brake pedal subassembly system includes a base 1 and a bolt vibrating disk 2, a switch base vibrating disk 3, a switch base sorting assembly 4, a loading table 5, a robotic arm 6, a bolt mounting assembly 7, and a switch base mounting assembly 8 mounted on the base 1;

[0057] The bolt vibrating disk 2 and the switch base vibrating disk 3 are arranged side by side. The bolt vibrating disk 2 is used to convey bolts to the bolt mounting assembly 7;

[0058] The switch base vibrating disk 3 is used to convey two types of switch bases to the switch base sorting assembly 4;

[0059] The switch base sorting assembly 4 is used to classify the two types of switch bases and convey them towards the switch base mounting assembly 8;

[0060] The bolt mounting assembly 7 and the switch base mounting assembly 8 are mounted on the robotic arm 6. The robotic arm 6 is used to drive the movement of the bolt mounting assembly 7 and the switch base mounting assembly 8;

[0061] The loading table 5 is used to place the brake pedal and the accelerator pedal to be assembled;

[0062] The bolt mounting assembly 7 is used to pick up bolts from the bolt vibrating disk 2 and then move to the loading table 5 to assemble the bolts onto the brake pedal and the accelerator pedal;

[0063] The switch base mounting assembly 8 is used to pick up the switch base from the switch base sorting assembly 4 and then move to the loading table 5 to assemble the switch base onto the brake pedal and the accelerator pedal.

[0064] Specifically, the base 1 is a rectangular workbench surface, and its top surface is used to mount the bolt vibrating disk 2, the switch base vibrating disk 3, the switch base sorting assembly 4, the loading table 5, the robotic arm 6, the bolt mounting assembly 7, and the switch base mounting assembly 8. Support feet and / or pulleys can be installed at the bottom of the base 1 to ensure the stable operation of the brake pedal subassembly system and facilitate the movement of the entire system. The base 1 can have only one frame or can also include a toolbox for convenient storage of tools.

[0065] As Figure 2As shown, the bolt vibrating bowl 2 and the switch base vibrating bowl 3 are arranged side by side. The bolt vibrating bowl 2 includes a bowl body 21 and a bolt chute 22. A plurality of bolts 30 are poured into the bowl body 21. After being vibrated and sorted in the bowl body 21, they enter the bolt chute 22 one by one. The bolt chute 22 conveys the plurality of bolts 30 in a straight line direction, facilitating the picking up of the bolts 30 by the bolt installation assembly 7.

[0066] As Figure 2 shown, the switch base vibrating bowl 3 is arranged side by side with the bowl body 21. Two types of switch bases are poured into the switch base vibrating bowl 3 together. The discharge port of the switch base vibrating bowl 3 is docked with the switch base distributing assembly 4, and the plurality of switch bases are sent into the switch base distributing assembly 4 one by one.

[0067] The switch base distributing assembly 4 is used to classify two types of switch bases. As Figure 2 shown, the classified first switch base 10 and second switch base 20 are each arranged in a row, facilitating the clamping by the switch base installation assembly 8.

[0068] As Figure 6 shown, the bolt installation assembly 7 and the switch base installation assembly 8 are installed on the robotic arm 6. The robotic arm 6 is used to drive the movement of the bolt installation assembly 7 and the switch base installation assembly 8. Specifically, the robotic arm 6 drives the bolt installation assembly 7 to move to the bolt vibrating bowl 2 to facilitate picking up the bolts, and then moves to the loading platform 5 to install the bolts on the brake pedal and the accelerator pedal. The robotic arm 6 also drives the switch base installation assembly 8 to move to the switch base distributing assembly 4 to facilitate clamping the switch base, and then moves to the loading platform 5 to install the switch base on the brake pedal and the accelerator pedal.

[0069] As Figure 5 shown, the loading platform 5 is used to hold the brake pedal and the accelerator pedal to be installed. Two switch bases need to be installed on the brake pedal and the accelerator pedal. The two switch bases have the same shape but different colors, one is dark and the other is light. However, the installation positions of the two switch bases are fixed and cannot be installed wrongly. Figure 5 The first installation position A in it is used to install the first switch base 10, and the second installation position B is used to install the second switch base 20.

[0070] In this embodiment, through the brake pedal sub-assembly system, the automatic assembly of the brake pedal and the accelerator pedal can be realized. There is no need to install the switch base and the bolt manually, which can improve the assembly efficiency and the assembly quality. Especially, through the switch base distributing assembly 4, the classification and conveying of two types of switch bases can be realized, avoiding the problem of misalignment of the switch base assembly and ensuring the safety of the assembly.

[0071] Furthermore, as Figures 2 - 4As shown, the switch base material distribution assembly 4 includes a first material chute 41, a second material chute 42, a first color sensor 43, and a material distribution cylinder 44;

[0072] The first material chute 41 is directly connected to the switch base vibrating disk 3. The first material chute 41 and the second material chute 42 are arranged side by side and communicated. At the communication part between the second material chute 42 and the first material chute 41, there are a first color sensor 43 and a material distribution cylinder 44. When the first color sensor 43 recognizes a dark-colored switch base, the material distribution cylinder 44 pushes the dark-colored switch base from the first material chute 41 into the second material chute 42.

[0073] Specifically, the first material chute 41 is used to convey the first switch base 10 to the switch base installation assembly 8, and the second material chute 42 is used to convey the second switch base 20 to the switch base installation assembly 8. When multiple switch bases enter the first material chute 41 one by one from the switch base vibrating disk 3, at this time, the types of the switch bases have not been classified, and both types of switch bases enter the front section of the first material chute 41. When the switch base passes through the first color sensor 43, when the first color sensor 43 recognizes a dark-colored switch base (i.e., the second switch base 20), the material distribution cylinder 44 pushes the second switch base 20 in a direction perpendicular to the first material chute 41 into the second material chute 42, thus realizing the classification of the switch bases. When the first switch base 10 (a light-colored switch base) passes through the first color sensor 43, the material distribution cylinder 44 does not act, and the first switch base 10 can smoothly pass through the first material chute 41. Therefore, the rear section of the first material chute 41 is all the first switch bases 10.

[0074] Furthermore, as Figures 3 - 4 shown, the switch base material distribution assembly 4 further includes a position sensor 45, a second color sensor 46, and a blowing pipe 47. The position sensor 45 is used to count the switch bases in the first material chute 41 and the second material chute 42. The blowing pipe 47 is arranged at the discharge port of the switch base vibrating disk 3, and the second color sensor 46 is arranged above the blowing pipe 47;

[0075] When the position sensor 45 detects that the switch bases in the first material chute 41 or the second material chute 42 are full, and the second color sensor 46 detects that this type of switch base is exactly at the discharge port, the blowing pipe 47 blows this switch base back into the switch base vibrating disk 3.

[0076] Specifically, as Figure 3 shown, the position sensor 45 located outside the first material chute 41 is arranged at the rear side of the material distribution cylinder 44 and is used to count the number of the first switch bases 10 entering the rear section of the first material chute 41. The second color sensor 46 is arranged above the blowing pipe 47, and the blowing pipe 47 is exactly aligned with the discharge port of the switch base vibrating disk 3.

[0077] When the in-place sensor 45 detects that the first switch base 10 in the first chute 41 is full, the second color sensor 46 detects that the switch base at the discharge port is a light-colored switch base (i.e., the first switch base 10). At this time, the air blowing pipe 47 is controlled to blow air, and the air blowing pipe 47 blows the first switch base 10 back into the switch base vibrating disk 3 to prevent the first switch base 10 from entering the first chute 41; if it is a dark-colored switch base (i.e., the second switch base 20), it will pass through normally.

[0078] As Figure 4 shown, another in-place sensor 45 is arranged outside the second chute 42 and corresponds to the connection between the first chute 41 and the second chute 42. This in-place sensor 45 can count the number of second switch bases 20 entering the second chute 42.

[0079] When the in-place sensor 45 detects that the second switch base 20 in the second chute 42 is full, the second color sensor 46 detects that the switch base at the discharge port is a dark-colored switch base (i.e., the second switch base 20). At this time, the air blowing pipe 47 is controlled to blow air, and the air blowing pipe 47 blows the second switch base 20 back into the switch base vibrating disk 3 to prevent the second switch base 20 from entering the first chute 41; if it is a light-colored switch base (i.e., the first switch base 10), it will pass through normally.

[0080] Further, as Figure 7 shown, the bolt installation assembly 7 includes a bolt motor 71, a screw rod 72, and a magnetic sleeve 73. The magnetic sleeve 73 is installed at the end of the screw rod 72. The bolt motor 71 is used to drive the screw rod 72 to rotate, and the magnetic sleeve 73 is used to adsorb the bolt 30. The bolt motor 71 drives the screw rod 72 to rotate, the screw rod 72 drives the magnetic sleeve 73 to rotate, and the magnetic sleeve 73 drives the adsorbed bolt 30 to rotate and install it on the brake pedal and the accelerator pedal.

[0081] Specifically, the magnetic sleeve 73 is provided with a hexagonal internal thread hole. The magnetic sleeve 73 can suck the bolt 30 from the bolt chute 22 of the bolt vibrating disk 2, and the bolt 30 enters the internal thread hole of the magnetic sleeve 73. When the robotic arm 6 brings the bolt installation assembly 7 above the first installation position A and the second installation position B of the loading platform 5, the magnetic sleeve 73 is further controlled to align with the first installation position A or the second installation position B. Then, the bolt motor 71 drives the screw rod 72 to rotate, the screw rod 72 drives the magnetic sleeve 73 to rotate, and the magnetic sleeve 73 drives the bolt 30 to rotate and screw into the previously placed switch base, realizing the connection of the brake pedal and the accelerator pedal.

[0082] Further, as Figure 7As shown, the bolt installation assembly 7 further includes a fixed bracket 74, a displacement cylinder 75, a push rod 76, a first slider 77, a second slider 78, a guide rail 79, a spring 791 and a guide rod 792;

[0083] The fixed bracket 74 is fixedly connected to the robotic arm 6. The displacement cylinder 75 is installed on the fixed bracket 74. One end of the push rod 76 is connected to the displacement cylinder 75, and the other end is connected to the first slider 77. The first slider 77 can slide along the guide rail 79. The bolt motor 71 is installed on the first slider 77. The second slider 78 is located below the first slider 77 and can slide along the guide rail 79. The spring 791 is sleeved on the guide rod 792 and is located between the first slider 77 and the second slider 78. One end of the guide rod 792 is fixedly connected to the first slider 77, and the other end is movably connected to the second slider 78. The magnetic sleeve 73 passes through the second slider 78 and is located below the second slider 78.

[0084] Specifically, the fixed bracket 74 is a long strip structure along the longitudinal direction. The fixed bracket 74 is fixedly connected to the robotic arm 6, and the robotic arm 6 can drive the bolt installation assembly 7 to move.

[0085] The displacement cylinder 75 is fixedly connected to the fixed bracket 74. The lower end of the displacement cylinder 75 is connected to the upper end of the push rod 76, and the lower end of the push rod 76 is fixedly connected to the first slider 77. The displacement cylinder 75 can drive the push rod 76 to expand and contract up and down, and the push rod 76 drives the first slider 77 to move up and down.

[0086] The guide rail 79 is fixedly installed on the fixed bracket 74 along the longitudinal direction. Both the first slider 77 and the second slider 78 can slide up and down along the guide rail 79.

[0087] A guide rod 792 and a spring 791 are installed between the first slider 77 and the second slider 78. The upper end of the guide rod 792 is fixedly connected to the first slider 77, and the lower end is movably connected to the second slider 78. The spring 791 is sleeved outside the guide rod 792, and the upper end of the spring 791 abuts against the first slider 77, and the lower end abuts against the second slider 78.

[0088] The bolt motor 71 is fixedly installed on the first slider 77, and the lower end of the bolt motor 71 passes through the first slider 77. The screw rod 72 passes through the second slider 78 and is movably connected to the second slider 78. The magnetic sleeve 73 is located below the second slider 78.

[0089] When the bolt installation assembly 7 is not working, the displacement cylinder 75 is not working. At this time, the push rod 76 retracts upward, so that the magnetic sleeve 73 also retracts upward.

[0090] When the bolt installation assembly 7 needs to work, the displacement cylinder 75 is activated, driving the push rod 76 to extend downward. The push rod 76 pushes the first slider 77 downward, and the first slider 77 drives the bolt motor 71 to move downward synchronously. At the same time, the first slider 77 presses the spring 791. After the spring 791 is compressed and deformed, it pushes the second slider 78, and the second slider 78 also moves downward. Finally, the magnetic sleeve 73 extends downward beyond the bottom of the switch base installation assembly 8, preventing interference between the bolt installation assembly 7 and the switch base installation assembly 8 during the operation of the bolt installation assembly 7.

[0091] Further, as Figures 8 - 10 shown, the switch base installation assembly 8 includes an installation bracket 81, a jaw assembly 82, a pressing cylinder 83, and a pressing plate 84;

[0092] The installation bracket 81 is fixedly connected to the robotic arm 6. The jaw assembly 82 and the pressing cylinder 83 are installed on the installation bracket 81. The pressing cylinder 83 is connected to the pressing plate 84 and can drive the pressing plate 84 to move up and down. At least a part of the jaw assembly 82 passes through the pressing plate 84 and extends below the pressing plate 84. The jaw assembly 82 is used to grasp the switch base.

[0093] Specifically, the installation bracket 81 can be fixedly connected to the fixed bracket 74 and is located on the side of the bolt installation assembly 7. The installation bracket 81 can be a long strip-shaped plate structure.

[0094] The jaw assembly 82 is installed on one side of the installation bracket 81, the pressing cylinder 83 is installed on the other side of the installation bracket 81. One end of the pressing plate 84 is connected to the pressing cylinder 83, and the other end extends below the jaw assembly 82.

[0095] Among them, the jaw assembly 82 is used to grasp the switch base. Driven by the robotic arm 6, it can place the switch base on the first installation position A or the second installation position B.

[0096] As Figure 9 shown, the pressing plate 84 is located below the jaw assembly 82. When the jaw assembly 82 grasps the first switch base 10, the pressing plate 84 can contact the outer edge of the first switch base 10. When the jaw assembly 82 places the first switch base 10 into the first installation position A, the jaw assembly 82 releases the first switch base 10. Subsequently, the pressing cylinder 83 drives the pressing plate 84 downward, and the pressing plate 84 can push the first switch base 10 to the bottom of the first installation position A, realizing the installation of the first switch base 10. Similarly, the installation of the second switch base 20 into the second installation position B is the same as that of the first switch base 10.

[0097] Further, as Figure 10As shown, the jaw assembly 82 includes a chassis 821, two moving blocks 822, and two profiling jaws 823. The chassis 821 is provided with two sliding grooves 8211. The moving blocks 822 are installed in the sliding grooves 8211 and can move relative to each other in the sliding grooves 8211. The profiling jaws 823 are fixedly connected to the moving blocks 822. The two profiling jaws 823 can open or close relative to each other. The pressing plate 84 includes two pressing strips 841. There is a hollow 842 between the two pressing strips 841. The profiling jaws 823 pass through the hollow 842.

[0098] Specifically, the chassis 821 is fixedly connected to the mounting bracket 81. The chassis 821 is provided with two sliding grooves 8211 located on the same radial line. The sliding grooves 8211 are respectively used to install a moving block 822. The moving block 822 can slide relative to each other along the radial direction in the sliding groove 8211. The two profiling jaws 823 are fixedly connected to the moving blocks 822.

[0099] When the two moving blocks 822 move relatively closer or farther away, they drive the two profiling jaws 823 to clamp or open relative to each other, thereby realizing the clamping or releasing of the switch base.

[0100] The two pressing strips 841 of the pressing plate 84 extend into the two side surfaces of the two profiling jaws 823. The profiling jaws 823 pass downward through the hollow 842. Therefore, the opening and closing of the profiling jaws 823 do not interfere with the pressing plate 84, and the up and down movement of the pressing plate 84 does not interfere with the profiling jaws 823 either.

[0101] Further, as Figure 10 shown, the profiling jaw 823 includes a first stepped surface 8231 and a second stepped surface 8232. The second stepped surface 8232 extends downward relative to the first stepped surface 8231. The inner side of the second stepped surface 8232 is arc-shaped. The first stepped surface 8231 is used to contact the top surface of the switch base, and the inner side of the second stepped surface 8232 is used to contact the edge of the switch base.

[0102] Specifically, the second stepped surface 8232 is located on the relatively outer side of the first stepped surface 8231 and extends downward. The inner side surfaces of the two second stepped surfaces 8232 are arc surfaces, which exactly correspond to the outer edge of the switch base 10. Therefore, when the two second stepped surfaces 8232 are closed, they can clamp the outer edge of the switch base 10. At the same time, the first stepped surface 8231 contacts the top surface of the switch base 10, ensuring the stability of the clamping.

[0103] Further, as Figure 5 shown, the loading table 5 includes a bearing table 51, a optical axis 52, and a rodless cylinder 53. The rodless cylinder 53 is used to drive the bearing table 51 to move back and forth along the optical axis 52. The bearing table 51 is used to place the brake pedal and the accelerator pedal.

[0104] Specifically, there are two sets of loading platforms 5, which are used to alternately push into the working positions. When a set of loading platforms 5 is placed with brake pedals and accelerator pedals to be assembled, the rodless cylinder 53 of this set of loading platforms 5 drives the carrier platform 51 to slide along the optical axis 52, and pushes the carrier platform 51 into the working position to prepare for the installation of the switch base and bolts.

[0105] The other set of loading platforms 5 slides back to the initial position. The staff places the brake pedals and accelerator pedals to be assembled on the carrier platform 51. After waiting for the previous set of loading platforms 5 to return, the other set of loading platforms 5 slides into the working position. Through the alternating work of the two sets of loading platforms 5, the assembly efficiency is improved.

[0106] Furthermore, as Figure 1 shown, it further includes a visual positioning unit 9. The visual positioning unit 9 includes a camera 91 and a light source 92. The camera 91 is used to obtain the installation positions of the brake pedal and the accelerator pedal, and the light source 92 provides light for the camera 91.

[0107] Specifically, the visual positioning unit 9 is installed on the robotic arm 6 and is located on the side of the bolt installation assembly 7 and the switch base installation assembly 8. When the bolt installation assembly 7 and the switch base installation assembly 8 pick up bolts and switch bases, the visual positioning unit 9 obtains the accurate positions of the first installation position A and the second installation position B on the brake pedal and the accelerator pedal through the camera 91, and controls the robotic arm 6 to accurately drive the movement of the bolt installation assembly 7 and the switch base installation assembly 8 to achieve the installation of bolts and switch bases.

[0108] In a preferred embodiment of the present invention, the working process of the brake pedal sub-assembly system is as follows:

[0109] Put the first switch base 10 and the second switch base 20 into the switch base vibrating disk 3. After the switch base vibrating disk 3 vibrates and sorts the two kinds of switch bases, they enter the first chute 41 one by one.

[0110] When the first color sensor 43 recognizes the second switch base 20, the material distribution cylinder 44 pushes the second switch base 20 in a direction perpendicular to the first chute 41 into the second chute 42, realizing the transportation of the second switch base 20 along the second chute 42 and the transportation of the first switch base 10 along the first chute 41.

[0111] The disk body 21 of the bolt vibrating disk 2 vibrates and sorts the bolts 30 and outputs them along the bolt chute 22.

[0112] The staff places the brake pedal and the accelerator pedal on the loading platform 5 and pushes them into the working position to be assembled.

[0113] The robotic arm 6 drives the switch base mounting assembly 8 to move to the switch base feeding assembly 4, and the switch base mounting assembly 8 picks up a switch base. Then, the robotic arm 6 drives the switch base mounting assembly 8 to move to the loading table 5 and mounts the switch base onto the brake pedal and the accelerator pedal.

[0114] The robotic arm 6 drives the bolt mounting assembly 7 to move to the end of the bolt chute 22, and the magnetic sleeve 73 of the bolt mounting assembly 7 picks up a bolt 30. The robotic arm 6 drives the bolt mounting assembly 7 to move to the loading table 5 and passes the bolt through the switch base for connecting the brake pedal and the accelerator pedal.

[0115] The present invention realizes the whole process of automatic feeding, picking up and mounting of two switch bases, which can improve the assembly efficiency, improve the assembly quality and ensure the assembly safety.

[0116] The above are only the principles and preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, based on the principle of the present invention, several other variants can also be made, which should also be regarded as the protection scope of the present invention.
