Detailed Implementation
[0143] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0144] Please also refer to Figures 1-10 This application provides some embodiments of a flexible assembly tooling for a bracket.
[0145] like Figure 1 and Figure 6 As shown, the flexible assembly fixture for brackets in this application includes: a movable stage 1, a rotating component 2, and at least two bracket assembly groups. The rotating component 2 is disposed on the movable stage 1; at least two mounting positions 231 are formed on the rotating component 2; the bracket assembly groups are disposed at the corresponding mounting positions 231; the bracket assembly groups include: a fender bracket assembly device 3 and a lamp bracket assembly device 4; the moving direction of the movable stage 1 is perpendicular to the rotation surface of the rotating component 2.
[0146] Specifically, the flexible bracket assembly fixture is placed on the side of the vehicle body 7 to be assembled, and assembles the fender bracket 5 and the lamp bracket onto the vehicle body 7. There can be two flexible bracket assembly fixtures, located on both sides of the vehicle body 7 to be assembled, to assemble the fender bracket 5 and the lamp bracket on both sides of the vehicle body 7. The moving table 1 can move, driving the rotating component 2, the bracket assembly group, and the fender bracket 5 and the lamp bracket on the bracket assembly group to move together. The direction of the moving table 1 is towards the location of the vehicle body 7 to be assembled, thereby moving the fender bracket 5 and the lamp bracket to the corresponding position of the vehicle body 7 to be assembled, and assembling and connecting them. Since the vehicle bodies 7 to be assembled are different, the fender bracket 5 and the lamp bracket to be assembled may also be different. There are at least two mounting positions 231, and each mounting position 231 is provided with a bracket assembly group. Different bracket assembly groups can be used to assemble different fender brackets 5 and different lamp brackets. Therefore, the rotating component 2 can rotate to change the position of the mounting position 231, so that different fender brackets 5 and different lamp brackets are assembled on the corresponding vehicle body 7 to be assembled.
[0147] The lamp holder is located near the front of the vehicle body 7 to be assembled, and the fender bracket 5 is located on the side of the lamp holder facing the rear of the vehicle body 7 to be assembled. The lamp holder and fender bracket 5 are located at the front and rear positions on the side of the vehicle body 7 to be assembled. The rotation surface of the rotating assembly 2 refers to the surface where the mounting position 231 on the rotating assembly 2 is located when it rotates. The moving direction of the rotating table is perpendicular to the rotation surface of the rotating assembly 2. The moving table 1 moves towards the side of the vehicle body 7 to be assembled, while the rotation surface of the rotating assembly 2 is parallel to the side of the vehicle body 7 to be assembled. All fender brackets 5 and all lamp holders are located on the same plane and are parallel to the side of the vehicle body 7 to be assembled. When the mounting position 231 is rotated to the position corresponding to the body 7 to be assembled, it can not only be put on the shelf (installed with the fender bracket 5 and the lamp bracket), but also move towards the body 7 to be assembled via the moving platform 1, so that the fender bracket 5 and the lamp bracket can be assembled together to receive the body 7 for assembly. It can be seen that the entire shelf and assembly process is simpler and more time-saving, and the fender bracket 5 and the lamp bracket can be assembled at the same time, which greatly improves the assembly efficiency of the body 7 to be assembled.
[0148] In addition, when the mounting position 231 is rotated to the position corresponding to the body 7 to be assembled, it is put on the frame. Since different bracket assembly groups are equipped with different fender brackets 5 and different lamp brackets, if it cannot be put on the frame, the bracket assembly group on the mounting position 231 does not match the fender bracket 5 and the lamp bracket. It may be that the wrong fender bracket 5 and lamp bracket were taken, or it may be that the mounting position 231 has not been rotated into place. Therefore, it is necessary to check whether it can be put on the frame to avoid misassembly.
[0149] In one implementation of the embodiments of this application, such as Figures 8-10 As shown, the fender bracket assembly device 3 includes a first translation component 31 and a first clamping component 32. The first translation component 31 is disposed at the corresponding mounting position 231; the first clamping component 32 is disposed on the first translation component 31; the first clamping component 32 is used to clamp the fender bracket 5.
[0150] Specifically, the first translation component 31 can move within a plane, thereby moving the first clamping component 32 and the clamped fender bracket 5. The movement of the moving platform 1 is for coarse adjustment of the position of the fender bracket 5 and the lamp bracket, while the translation of the first translation component 31 is for fine adjustment of the position of the fender bracket 5, so that the fender bracket 5 can precisely engage with the vehicle body 7 to be assembled. The movement direction of the first translation component 31 includes: a first direction, which is consistent with the movement direction of the moving platform 1. The movement direction of the first translation component 31 may also include: a second direction, which is perpendicular to the first direction.
[0151] In one implementation of the embodiments of this application, such as Figure 8As shown, the first clamping assembly 32 includes: a base 321, a first positioning pin 322, a clamping drive 323, and a clamp 324. The base 321 is disposed on the first translation assembly 31; the first positioning pin 322 is disposed on the base 321 and is used to position the fender bracket 5; the clamping drive 323 is disposed on the base 321; the clamp 324 is rotatably disposed on the clamping drive 323; the clamping drive 323 drives the clamp 324 to rotate so that the fender bracket 5 is clamped between the clamp 324 and the base 321.
[0152] Specifically, the first locating pin 322 is used to locate the fender bracket 5. Once the fender bracket 5 is properly positioned, it can be clamped, allowing it to fit and overlap with the vehicle body 7 to be assembled. If the fender bracket 5 is not properly positioned, it cannot form a good overlap with the vehicle body 7. The clamp 324 is used to clamp the fender bracket 5. The clamp 324 is movable relative to the base 321, allowing the fender bracket 5 to be clamped and released via the clamp 324 and the base 321. The clamping drive 323 is used to drive the clamp 324 to rotate, thereby clamping or releasing the fender bracket 5.
[0153] The clamping drive 323 is a clamping cylinder with a handle on the side. The clamp 324 is rotatably connected to the clamping cylinder. When the handle is turned, the clamping cylinder drives the clamp 324 to rotate, thereby clamping or releasing the fender bracket 5.
[0154] In one implementation of the embodiments of this application, such as Figures 9-10 As shown, the seat 321 includes a first abutment portion 3211 and a second abutment portion 3212. The first abutment portion 3211 and the second abutment portion 3212 are respectively located on adjacent sides of the clamp 324; a first positioning pin 322 is disposed on the first abutment portion 3211, and the first abutment portion 3211 forms a first positioning surface.
[0155] Specifically, both the first abutment portion 3211 and the second abutment portion 3212 are abutted by the fender bracket 5. A first positioning pin 322 is provided on the first abutment portion 3211. The fender bracket 5 abuts against the first abutment portion 3211 and cooperates with the first positioning pin 322 to achieve positioning of the fender bracket 5. The clamp 324 moves towards the second abutment portion 3212, applying pressure to the second abutment portion 3212 to clamp the fender. A groove or through hole can be formed on the fender bracket 5 to cooperate with the first positioning pin 322 and achieve positioning of the fender bracket 5. A first positioning surface is formed on the first abutment portion 3211, allowing the fender bracket 5 to be positioned in three dimensions by the first positioning pin 322 and the first positioning surface. There can be two or more first positioning pins 322, improving positioning accuracy. A sensor 33 is also provided on the base 321 to sense whether the fender bracket 5 is present at the first positioning pin 322. When the sensor 33 senses the fender bracket 5, the clamp 324 is controlled by the clamping drive 323 to clamp the fender bracket 5.
[0156] In one implementation of the embodiments of this application, such as Figures 8-10 As shown, the first translation component 31 includes: a first substrate 311, a first sliding plate 312, a second sliding plate 313, a first limiting member 314, and a second limiting member 315. The first substrate 311 is disposed at the mounting position 231; the first sliding plate 312 is slidably connected to the first substrate 311; the second sliding plate 313 is slidably connected to the first sliding plate 312; the first limiting member 314 is disposed on the first substrate 311 and is used to limit the sliding range of the first sliding plate 312; the second limiting member 315 is disposed on the first sliding plate 312 and is used to limit the sliding range of the second sliding plate 313.
[0157] Specifically, the first translation component 31 has two directions of movement: a first direction and a second direction. The first slide plate 312 slides along the second direction, and the second slide plate 313 moves along the first direction. The direction of movement of the second slide plate 313 is the same as that of the moving stage 1. The sliding connection between the first slide plate 312 and the first substrate 311 can be a guide rail slider structure, and the sliding connection between the second slide plate 313 and the first slide plate 312 can also be a guide rail slider structure. The sliding range of the first slide plate 312 is limited by a first limiting member 314. There can be two first limiting members 314, located on both sides of the first slide plate 312, to limit the sliding range of the first slide plate 312. The sliding range of the second slide plate 313 is limited by a second limiting member 315. There can be two second limiting members 315, located on both sides of the second slide plate 313, to limit the sliding range of the second slide plate 313.
[0158] In one implementation of the embodiments of this application, such as Figures 8-10As shown, the first translation component 31 includes a first position sensor 316 and a second position sensor 317. The first position sensor 316 is disposed on the first substrate 311 and is used to sense the position of the first slide plate 312; the second position sensor 317 is disposed on the first slide plate 312 and is used to sense the position of the second slide plate 313.
[0159] Specifically, based on the setting of the first limiting member 314 and the second limiting member 315, a first position sensor 316 and a second position sensor 317 are set. The first position sensor 316 is used to sense the position of the first slide plate 312. Two first position sensors 316 can be set, so that two positions of the first slide plate 312 can be detected. For example, when the first slide plate 312 slides close to one of the first limiting members 314, it is sensed by one first position sensor 316, and when the first slide plate 312 slides close to another first limiting member 314, it is sensed by another first position sensor 316. The second position sensor 317 is used to sense the position of the second slide plate 313. Two second position sensors 317 can be set, so that two positions of the second slide plate 313 can be detected. For example, when the second slide plate 313 slides close to one of the second limiting members 315, it is sensed by one second position sensor 317, and when the second slide plate 313 slides close to another second limiting member 315, it is sensed by another second position sensor 317.
[0160] In one implementation of the embodiments of this application, such as Figures 6-7 As shown, the rotating assembly 2 includes: a bracket 21, a rotating member 22, a positioning assembly 24, and at least two extension arms 23. The bracket 21 is disposed on the moving stage 1; the rotating member 22 is rotatably connected to the bracket 21; the extension arms 23 are disposed on the rotating member 22; the positioning assembly 24 is disposed on the rotating member 22; mounting positions 231 are formed on the extension arms 23; at least two extension arms 23 are disposed around the axis of rotation of the rotating member 22; the positioning assembly 24 is used to fix the rotating member 22 and to identify the extension arms 23 at the corresponding positions of the positioning assembly 24.
[0161] Specifically, bracket 21 provides support, while rotating component 22 can rotate. Rotating component 22 is equipped with a drive component, which drives its rotation. Positioning component 24 fixes the position of rotating component 22 and identifies the extension arm 23 at the corresponding position. Positioning component 24 positions rotating component 22, ensuring the fender bracket 5 and lamp bracket mounted on the bracket assembly on extension arm 23 are accurately positioned and correspond to the positions of the vehicle body 7 to be assembled. Mounting positions 231 are formed on extension arm 23. Different mounting positions 231 mount different bracket assemblies, and different extension arms 23 mount different bracket assemblies. By identifying the extension arm 23 at the corresponding position of positioning component 24, the bracket assembly at that position can be identified, thus determining the fender bracket 5 and lamp bracket on the bracket assembly, thereby assembling the corresponding fender bracket 5 and lamp bracket onto the vehicle body 7.
[0162] In one implementation of the embodiments of this application, such as Figures 6-7 As shown, the positioning assembly 24 includes: a sensing group 242, a limiter 243, and at least two protrusions 241. The protrusions 241 are disposed on the rotating member 22, and each protrusion 241 has a limiting portion and a sensing portion. The sensing group 242 is disposed on the bracket 21 and is used to sense the sensing portion. The limiter 243 is disposed on the bracket 21 and is used to cooperate with the limiting portion to restrict the rotation of the protrusions 241. At least two protrusions 241 are arranged around the axis of rotation of the rotating member 22, and the sensing portions on different protrusions 241 are different.
[0163] Specifically, protrusion 241 is disposed on rotating member 22 and arranged around the axis of rotation of rotating member 22. When rotating member 22 rotates, protrusion 241 rotates accordingly, forming a circular trajectory. Protrusion 241 is provided with a limiting part and a sensing part. Support 21 is provided with a limiting device 243 and a sensing group 242. The limiting device 243 cooperates with the limiting part to limit the position of protrusion 241 and rotating member 22, thus fixing the position of rotating member 22. The sensing group 242 and the sensing part cooperate to identify protrusion 241, and thus identify the corresponding extension arm 23. Specifically, the sensing parts on each protrusion 241 are different. When the sensing part is sensed by the sensing group 242, different sensing parts can be distinguished, thereby realizing the identification of protrusion 241. For example, the number of sensing parts on each protrusion 241 is different, and the sensing group 242 identifies each protrusion 241 by the difference in the number of sensed parts detected.
[0164] The limiting part can be a limiting hole or a limiting groove, and the limiter 243 can be a telescopic pin. The telescopic pin is inserted into the limiting hole or the limiting groove to fix the protrusion 241, so that the rotating part 22 and the protrusion 241 cannot rotate. One or more limiting parts can be used, and different types can be used. For example, the limiting part can use a limiting hole and a limiting groove, and each can be equipped with a corresponding limiter 243. The structure of the telescopic pin is also different depending on the type of limiting part. The shape of the telescopic pin matches the shape of the limiting part.
[0165] In one implementation of the embodiments of this application, such as Figure 3 As shown, a standing position 25 is provided on the side of the support 21, and the extension arm 23 rotates to the corresponding position of the standing position 25.
[0166] Specifically, a standing position 25 can be provided on the side of the bracket 21 for the assembly personnel to stand on. When the extension arm 23 rotates to the position corresponding to the standing position 25, the fender bracket assembly device 3 and the lamp bracket assembly device 4 on the mounting position 231 also rotate to the position corresponding to the standing position 25. Then the assembly personnel can load the fender bracket 5 onto the fender bracket assembly device 3 and the lamp bracket onto the lamp bracket assembly device 4.
[0167] In one implementation of the embodiments of this application, such as Figures 4-5 As shown, the moving stage 1 includes: a second base plate 11, a third sliding plate 12, a third limiting member 13, and a locking member 14. The third sliding plate 12 is slidably connected to the second base plate 11; the third limiting member 13 is disposed on the second base plate 11 and is used to limit the sliding range of the third sliding plate 12; the locking member 14 is disposed on the second base plate 11 and is used to lock the third sliding plate 12.
[0168] Specifically, the sliding connection between the third slide plate 12 and the second substrate 11 can adopt a guide rail slider structure. The third limiting member 13 restricts the sliding range of the third slide plate 12. There can be two third limiting members 13, located on opposite sides of the third slide plate 12. There can also be two locking members 14. When the third slide plate 12 abuts against one third limiting member 13, one locking member 14 locks and fixes the third slide plate 12; when the third slide plate 12 abuts against another third limiting member 13, the other locking member 14 locks and fixes the third slide plate 12. A buffer 15 can also be provided on the second substrate 11 to buffer the sliding of the third slide plate 12. When the third slide plate 12 approaches the third limiting member 13, it first contacts the buffer 15, is decelerated by the buffering effect of the buffer 15, abuts against the third limiting member 13, and is finally locked by the locking member 14. A proximity switch 16 can also be provided on the second substrate 11 to determine the position of the third slide plate 12. When the third slide plate 12 abuts against the third limiting member 13, it also approaches the proximity switch 16, thereby opening the locking member 14 for locking. Two proximity switches 16 can be provided, located on both sides of the third slide plate 12 respectively.
[0169] The locking member 14 includes a limiting block, a rotating hook, and a rotating drive member. The limiting block is disposed on the third slide plate 12, and the rotating hook and the rotating drive member are both disposed on the second base plate 11. When the limiting block on the second slide plate 313 slides to the position of the corresponding rotating hook, the second slide plate 313 abuts against the third limiting member 13. The rotating drive member drives the rotating hook to rotate and hangs on the limiting block, and cooperates with the third limiting member 13 to fix the second slide plate 313.
[0170] In one implementation of this application, the lamp holder assembly device 4 includes: a second translation component and a second clamping component. The second translation component is disposed at a corresponding mounting position; the second clamping component is disposed on the second translation component; the second clamping component is used to clamp the lamp holder.
[0171] Specifically, the lamp holder assembly device 4 has a similar structure to the fender bracket assembly device 3. The lamp holder assembly device 4 includes a second translation component and a second clamping component. The second translation component can move within a plane, thereby moving the second clamping component and the clamped lamp holder. The movement of the moving platform 1 is for coarse adjustment of the position of the fender bracket 5 and the lamp holder, while the translation of the second translation component is for fine adjustment of the position of the lamp holder, so that the lamp holder precisely aligns with the vehicle body 7 to be assembled. The movement direction of the second translation component includes a first direction, which is consistent with the movement direction of the moving platform 1. The movement direction of the second translation component may also include a second direction, which is perpendicular to the first direction.
[0172] In one implementation of this application, the second clamping assembly includes: a base, a first positioning pin, a clamping drive, and a clamp. The base is disposed on the second translation assembly; the first positioning pin is disposed on the base and is used to position the lamp holder; the clamping drive is disposed on the base; the clamp is rotatably disposed on the clamping drive; the clamping drive drives the clamp to rotate, so that the lamp holder is clamped between the clamp and the base.
[0173] Specifically, the first locating pin is used to position the lamp holder. Once the lamp holder is properly positioned, it can be clamped, allowing it to fit and overlap with the vehicle body to be assembled. If the lamp holder is not properly positioned, it cannot achieve a proper overlap with the vehicle body. The clamp is used to clamp the lamp holder. The clamp can move relative to the base, allowing the lamp holder to be clamped and released via the clamp and base. The clamping drive is used to drive the clamp to rotate, thereby clamping or releasing the lamp holder.
[0174] The clamping drive uses a clamping cylinder, and a handle is provided on the side of the clamping cylinder. The clamp is rotatably connected to the clamping cylinder. When the handle is turned, the clamping cylinder drives the clamp to rotate, thereby clamping or releasing the lamp bracket.
[0175] In one implementation of this application, the base includes a first abutment portion and a second abutment portion. The first abutment portion and the second abutment portion are respectively located on adjacent sides of the clamp; a first positioning pin is disposed on the first abutment portion, and the first abutment portion forms a first positioning surface.
[0176] Specifically, both the first and second abutment portions are for the lamp holder to abut against. A first positioning pin is provided on the first abutment portion. The lamp holder abuts against the first abutment portion and engages with the first positioning pin to position the lamp holder. The clamp moves towards the second abutment portion, applying pressure to the second abutment portion to clamp the lamp. A groove or through hole can be formed on the lamp holder to engage with the first positioning pin and achieve positioning of the lamp holder. A first positioning surface is formed on the first abutment portion, allowing the lamp holder to be positioned in three dimensions via the first positioning pin and the first positioning surface. There can be two or more first positioning pins, improving positioning accuracy.
[0177] The second translation component differs from the first translation component in specific location and shape, but the components included in the second translation component are the same as those included in the first translation component, and the functions of each component are the same. The second translation component includes: a first base plate, a first sliding plate, a second sliding plate, a first limiting member, and a second limiting member. The first base plate is disposed in a mounting position; the first sliding plate is slidably connected to the first base plate; the second sliding plate is slidably connected to the first sliding plate; the first limiting member is disposed on the first base plate and is used to limit the sliding range of the first sliding plate; the second limiting member is disposed on the first sliding plate and is used to limit the sliding range of the second sliding plate. The second translation component includes: a first position sensor and a second position sensor. The first position sensor is disposed on the first base plate and is used to sense the position of the first sliding plate; the second position sensor is disposed on the first sliding plate and is used to sense the position of the second sliding plate.
[0178] like Figures 1-3 As shown, based on any of the above embodiments of the flexible assembly tooling for the bracket, the present application also proposes a flexible assembly device for the bracket, which includes the flexible assembly tooling for the bracket described above.
[0179] In one implementation of the embodiments of this application, such as Figures 1-2 As shown, the bracket flexible assembly device also includes: a body conveying and positioning fixture 6. The body conveying and positioning fixture 6 is used to convey the body to be assembled and to position the body to be assembled; the bracket flexible assembly fixture is located on the side of the body conveying and positioning fixture 6.
[0180] Specifically, the body conveying and positioning fixture 6 is used to convey the body to be assembled. It transports the body from the previous station to this station for bracket assembly (including fender bracket assembly and lamp bracket assembly), and then transports the body to the next station. During bracket assembly at this station, the body is secured to facilitate bracket assembly. Two flexible bracket assembly fixtures are located on the side of the body conveying and positioning fixture 6, one on each side.
[0181] In one implementation of the embodiments of this application, such as Figure 2 As shown, the vehicle body conveying and positioning fixture 6 includes: a positioning frame 61, a lifting frame 62, and a conveying platform 63. The lifting frame 62 is disposed on the positioning frame 61; the conveying platform 63 moves on the lifting frame 62 and is used to carry and convey the vehicle body to be assembled; when the lifting frame 62 descends, the positioning frame 61 carries the vehicle body to be assembled and positions the vehicle body to be assembled.
[0182] Specifically, the positioning frame 61 is used to position the car body to be assembled, the lifting frame 62 is used to lift the car body to be assembled, and the conveyor platform 63 is used to carry the car body to be assembled and move it to various workstations. When conveying the car body to be assembled, the conveyor platform 63 is at a relatively high height. After reaching the workstation, it is lowered by the lifting frame 62, and the conveyor platform 63 lowers accordingly, separating the car body to be assembled from the conveyor platform 63. The car body to be assembled falls onto the positioning frame 61 and is fixed by the positioning frame 61. When the car body to be assembled completes the bracket assembly at this workstation, it is raised by the lifting frame 62, and the conveyor platform 63 rises accordingly. The car body to be assembled then contacts the conveyor platform 63 and separates from the positioning frame 61. The conveyor platform 63 can then carry the car body to be assembled and transport it to the next workstation.
[0183] In one implementation of the embodiments of this application, such as Figures 1-2 As shown, the positioning frame 61 is provided with a second positioning pin 611 and a positioning block 612, and a second positioning surface is formed on the positioning block 612. Specifically, the vehicle body to be assembled is three-dimensionally positioned by means of the second positioning pin 611 and the second positioning surface. The positioning frame 61 is provided with reference holes, and there can be multiple reference holes. A vehicle body coordinate system is established based on the reference holes, which facilitates the accuracy detection of all first positioning pins, all second positioning pins 611, all first positioning surfaces, and all second positioning surfaces.
[0184] like Figures 11-12 As shown, based on any of the above embodiments of the flexible assembly device for the support, embodiments of this application also provide an assembly method based on the flexible assembly device for the support, including the following steps:
[0185] Step S100: According to the vehicle model to be assembled, control the rotating component to rotate to the target position;
[0186] Step S200: Control the fender bracket assembly device to install the fender bracket, and control the lamp bracket assembly device to install the lamp bracket.
[0187] Step S300: Control the moving platform to move towards the direction of the vehicle body to be assembled;
[0188] Step S400: Control the fender bracket assembly device to make the fender bracket overlap with the vehicle body to be assembled; after the fender bracket and the vehicle body to be assembled are fixedly connected, control the fender bracket assembly device to disengage from the fender bracket.
[0189] Step S500: Control the lamp bracket assembly device to make the lamp bracket overlap with the vehicle body to be assembled; after the lamp bracket and the vehicle body to be assembled are fixedly connected, control the lamp bracket assembly device to release the lamp bracket.
[0190] Step S600: Control the moving platform to move away from the vehicle body to be assembled.
[0191] Specifically, since there may be multiple vehicle models to be assembled with, it is necessary to determine the specific model and then control the rotating assembly to rotate to the target position. The target position is where the types of fender bracket mounting components and lamp bracket mounting components on the rotating assembly correspond to the vehicle model being assembled with. Because different vehicle models have different types of fender brackets and lamp brackets, the corresponding types of fender bracket and lamp bracket mounting components are rotated to their relative positions for each vehicle model, allowing the compatible fender brackets and lamp brackets to be assembled onto the corresponding vehicle body.
[0192] After rotating the components to the target position, the fender bracket and the lamp bracket can be mounted on the fender bracket assembly device. Assembly can be performed manually by personnel or by an assembly robot. After mounting, the moving platform can be controlled to move towards the vehicle body to be assembled, bringing the fender bracket and lamp bracket closer to the vehicle body.
[0193] During assembly, the fender bracket can be assembled first, followed by the lamp bracket; or the lamp bracket can be assembled first, followed by the fender bracket; or the lamp bracket and fender bracket can be assembled simultaneously. In other words, steps S400 and S500 are not sequential. When assembling the fender bracket, the fender bracket is first connected to the vehicle body to be assembled using the fender bracket assembly device, then the fender bracket and the vehicle body are fixedly connected, and finally the fender bracket assembly device is disengaged from the fender bracket to complete the assembly. Similarly, when assembling the lamp bracket, the lamp bracket is first connected to the vehicle body to be assembled using the lamp bracket assembly device, then the lamp bracket and the vehicle body are fixedly connected, and finally the lamp bracket assembly device is disengaged from the lamp bracket to complete the assembly. Finally, to facilitate the movement of the vehicle body to be assembled and the assembly of the next vehicle body to be assembled, the moving platform is moved away from the vehicle body to be assembled, returning to its original position, thus ending the bracket assembly of the vehicle body to be assembled.
[0194] When mounting the fender bracket, the first clamp assembly is opened, and after the fender bracket is placed in, the first clamp assembly is controlled to clamp the fender bracket. Specifically, the clamping drive is first controlled to open the clamp, positioning the fender bracket at the corresponding position of the locating pin, and then the clamping drive is controlled to clamp the fender bracket. When mounting the lamp bracket, the second clamp assembly is opened, and after the lamp bracket is placed in, the second clamp assembly is controlled to clamp the lamp bracket. Specifically, the clamping drive is first controlled to open the clamp, positioning the lamp bracket at the corresponding position of the locating pin, and then the clamping drive is controlled to clamp the lamp bracket.
[0195] Step S100 specifically includes:
[0196] Step S110: Determine the target extension arm corresponding to the vehicle model to be assembled; the target extension arm is one of the extension arms.
[0197] Step S120: Control the rotating component to rotate until the target extension arm rotates to the corresponding position of the positioning component. Then, control the rotating component to stop rotating and control the positioning component to fix the rotating component so that the rotating component is located at the target position.
[0198] Specifically, after determining the vehicle model to be assembled, the corresponding target extension arm is determined based on the model. Once the target extension arm is determined, it needs to be rotated to the target position. The rotation can be controlled either gradually or continuously. In gradual rotation, the angle of each rotation is the included angle between the two extension arms, and one extension arm is replaced with the corresponding positioning component each time. Continuous rotation involves rotating at a slower speed until the target extension arm reaches the target position. At this point, the rotation is stopped, and the positioning component is used to fix the rotation to prevent further rotation.
[0199] Specifically, step S120 includes:
[0200] Step S121: Control the rotating component to rotate until the sensor group senses the corresponding sensing unit, then control the rotating component to stop rotating;
[0201] Step S122: Control the limiter to match the limit part to fix the rotating part and make the rotating assembly located at the target position;
[0202] Specifically, since the sensing elements on each protrusion are different, each protrusion has a corresponding extension arm. Determining the position of the protrusion also determines the position of the extension arm. When the sensing group detects the corresponding sensing element, it indicates that the protrusion has rotated to the corresponding position of the sensing group, and the target extension arm has also rotated to the corresponding position of the positioning component. At this point, the rotating component can be controlled to stop rotating. To fix the rotating component, a limit switch limits the limiting part to fix the rotating component and keep the rotating component stationary at the target position.
[0203] Step S400 specifically includes:
[0204] Step S410: Control the first translation component to move the fender bracket and connect it with the vehicle body to be assembled;
[0205] Step S420: After the fender bracket is fixedly connected to the vehicle body to be assembled, control the first clamping assembly to release the fender bracket and control the first translation assembly to move back to its original position.
[0206] Specifically, the first translation component is controlled to move the fender bracket so that it overlaps with the vehicle body to be assembled. After the fender bracket and the vehicle body are fixedly connected, the first clamping component is controlled to release the fender bracket. Finally, the first translation component is controlled to move back to its original position, and the fender bracket assembly device is disengaged from the fender bracket.
[0207] Step S500 specifically includes:
[0208] Step S510: Control the second translation component to move the lamp bracket and connect it with the vehicle body to be assembled;
[0209] Step S520: After fixing the lamp bracket to the vehicle body to be assembled, control the second clamp assembly to release the lamp bracket and control the second translation assembly to move back to its original position.
[0210] Specifically, the second translation component is controlled to move the lamp bracket so that it overlaps with the vehicle body to be assembled. After the lamp bracket and the vehicle body are fixedly connected, the second clamping component is controlled to release the lamp bracket. Finally, the second translation component is controlled to move back to its original position, and the lamp bracket assembly device is detached from the lamp bracket.
[0211] Before step S100, the assembly method further includes:
[0212] Step S10: Control the vehicle body conveying and positioning fixture to convey the vehicle body to be assembled to the side of the bracket flexible assembly fixture, and position the vehicle body to be assembled.
[0213] Specifically, the vehicle body conveying and positioning fixture is controlled to convey the vehicle body to be assembled to the side of the bracket flexible assembly fixture, and to position the vehicle body to be assembled so that the bracket flexible assembly fixture can assemble the fender bracket and the lamp bracket.
[0214] Step S10 specifically includes:
[0215] Step S11: Control the conveyor platform to convey the car body to be assembled to the side of the bracket flexible assembly fixture;
[0216] Step S12: Control the lifting frame to lower the conveyor platform so that the car body to be assembled is located on the positioning frame and the conveyor platform is separated from the car body to be assembled.
[0217] Step S13: Control the positioning frame to position the car body to be assembled.
[0218] Specifically, the conveyor platform is moved to transport the car body to be assembled to this workstation, specifically to the side of the flexible assembly fixture. Then, the lifting frame is lowered, causing the car body to descend and land on the positioning frame. The conveyor platform continues to descend and separates from the car body. Finally, the positioning frame positions and secures the car body for assembly, facilitating the assembly of the fender bracket and lamp bracket.
[0219] After step S600, the assembly method further includes:
[0220] Step S700: Control the body car body conveying positioning fixture to release the positioning and convey the body car body to be assembled away from the side of the bracket flexible assembly fixture.
[0221] Specifically, after the fender bracket and lamp bracket are assembled, the body transport positioning fixture is controlled to transport the body to be assembled away from the side of the bracket flexible assembly fixture.
[0222] Step S700 specifically includes:
[0223] Step S701: Control the positioning frame to release the positioning of the vehicle body to be assembled;
[0224] Step S702: Control the lifting frame to raise the conveyor platform so that the car body to be assembled is located on the conveyor platform and the positioning frame is separated from the car body to be assembled.
[0225] Step S703: Control the conveyor platform to convey the car body to be assembled away from the side of the flexible assembly tooling on the support.
[0226] Specifically, after assembling the fender bracket and lamp bracket, the positioning frame is released from its position on the vehicle body to be assembled, thus detaching the vehicle body. Then, the lifting frame is raised to bring the transport platform into contact with the vehicle body. The transport platform continues to rise, separating the positioning frame from the vehicle body. Finally, the transport platform carries the vehicle body away from the side of the flexible assembly fixture and moves to the next workstation.
[0227] Before step S100, the assembly method further includes:
[0228] Step S1: Control the moving platform to move towards the overlapping position;
[0229] Step S2: Control the first translation component and the second translation component at the corresponding positions to move to the overlapping position, and perform positioning accuracy detection and adjustment on the first positioning pin, the second positioning pin, the first positioning surface and the second positioning surface based on the vehicle body coordinate system, so that the positioning accuracy is within the preset accuracy range;
[0230] Step S3: After controlling the rotating component to rotate, continue to control the first translation component and the second translation component at the corresponding position to move to the overlapping position, and perform positioning accuracy detection and adjustment on the first positioning pin, the second positioning pin, the first positioning surface and the second positioning surface based on the vehicle body coordinate system, so that the positioning accuracy is within the preset accuracy range, until the positioning accuracy detection of all first positioning pins, all second positioning pins, all first positioning surfaces and all second positioning surfaces is completed.
[0231] Step S4: Control the moving platform, the first translation component and the second translation component to move away from the overlapping position to return to their original positions.
[0232] Specifically, the preset accuracy range is [-0.1mm, 0.1mm], and the positioning accuracy is ≤ ±0.1mm. During positioning accuracy testing, the fender bracket and lamp bracket are not mounted, nor is the vehicle body to be assembled conveyed to the side of the flexible assembly fixture. Instead, the moving platform is directly controlled to move to the position where the third sliding plate abuts against the third limiting member and the locking member is engaged. The first translation component is controlled to move to the position where the first sliding plate abuts against the first limiting member and the second sliding plate abuts against the second limiting member. The second translation component is controlled to move to the position where the first sliding plate abuts against the first limiting member and the second sliding plate abuts against the second limiting member. In other words, although the fender bracket and lamp bracket are not mounted, and the vehicle body to be assembled is not conveyed, the moving platform, the first translation component, and the second translation component are moved to the overlapping position. The positioning accuracy of all first positioning pins, all second positioning pins, all first positioning surfaces, and all second positioning surfaces is tested at the overlapping position.
