[0038] During vehicle production, brake discs and shock absorbers need to be assembled. This pre-assembly process involves tightening the retaining nuts on the ends of the shock absorbers and inserting the brake disc's screw into the shock absorber's mounting holes. Researchers have found that the pre-assembly of shock absorbers and brake discs is currently done manually, which is inefficient and increases labor intensity.

[0039] The utility model provides an assembling device, aiming to solve the technical problem of low working efficiency when pre-assembling a shock absorber and a brake disc.

[0040] See also Figure 1In one embodiment of the present invention, the assembly device 520 includes a transfer robot 100, a carrying mechanism 200, a tightening mechanism 300 and a photographing mechanism 400. The carrying mechanism 200, the tightening mechanism 300 and the photographing mechanism 400 are arranged at circumferential intervals around the transfer robot 100. A loading station 511 is provided below the photographing mechanism 400, and the photographing mechanism 400 is electrically connected to the transfer robot 100; the transfer robot 100 can transfer the shock absorber 610 from the carrying mechanism 200 to the tightening mechanism 300, and after the tightening mechanism 300 tightens the fastening nut of the shock absorber 610, the shock absorber 610 can be transferred to the brake disc 620 of the loading station 511.

[0041] The technical solution of the present utility model, by providing a carrying mechanism 200 for carrying the shock absorber 610, a tightening mechanism 300 for tightening the fastening nuts at the ends of the shock absorber 610, and a transfer robot 100 for transporting the shock absorber 610, replaces manual pre-assembly of the shock absorber 610 and the brake disc 620, thereby improving work efficiency and reducing labor intensity. In this embodiment, the carrying mechanism 200 is used to carry the shock absorber 610, the tightening mechanism 300 is used to tighten the fastening nuts at the ends of the shock absorber 610, and the transfer robot 100 is used to transport the shock absorber 610. The shooting mechanism 400 is used to obtain the position information of the brake disc 620 at the loading station 511, and transmit the obtained position information to an external controller. The external controller can control the operation of the transfer robot 100 according to the position information of the brake disc 620. After the tightening mechanism 300 tightens the fastening nut of the shock absorber 610, the transfer robot 100 can transfer the tightened shock absorber 610 to the brake disc 620 at the loading station 511, and pass the screw 621 of the brake disc 620 through the mounting hole of the shock absorber 610. Specifically, when pre-assembling the brake disc 620 and the shock absorber 610, the transfer robot 100 transfers the shock absorber 610 at the support mechanism 200 to the tightening mechanism 300. After the tightening mechanism 300 tightens the fastening nut of the shock absorber 610, the external controller controls the transfer robot 100 to operate according to the position information of the brake disc 620, so as to transfer the tightened shock absorber 610 to the brake disc 620 at the loading station 511 and insert the screw 621 of the brake disc 620 into the mounting hole of the shock absorber 610. The assembly device 520 uses a machine instead of manual labor to complete the pre-assembly of the shock absorber 610 and the brake disc 620, which can improve work efficiency and reduce the labor intensity of workers. The assembly device 520 is applied to the field of vehicle production technology.

[0042] See also Figure 2In one embodiment of the present invention, the tightening mechanism 300 includes a mounting frame 310, a clamping assembly 320, and a tightening assembly 330. The clamping assembly 320 includes a driving body 321 and two clamping blocks 322 spaced apart from each other on the driving body 321. The driving body 321 is mounted on the mounting frame 310 and is capable of driving the two clamping blocks 322 to move toward or away from each other. In this embodiment, the driving body 321 can drive the two clamping blocks 322 toward each other to clamp the shock absorber 610, and can also drive the two clamping blocks 322 away from each other to loosen the shock absorber 610. In a specific embodiment, the driving body 321 can be a bidirectional drive cylinder 211, and the two clamping blocks 322 each have an arcuate surface formed on the facing side, and the arcuate surface matches the outer surface of the shock absorber 610.

[0043] The tightening assembly 330 includes a driving member 331, a mounting base 332 slidably mounted on the mounting frame 310, and a tightening gun 333 mounted on the mounting base 332. The driving member 331 can drive the mounting base 332 to move toward or away from the clamping assembly 320, thereby driving the tightening gun 333 to move toward or away from the clamping assembly 320. In this embodiment, the driving member 331 can drive the mounting base 332 to move toward or away from the clamping assembly 320, thereby driving the tightening gun 333 mounted on the mounting base 332 to move toward or away from the clamping assembly 320. Specifically, when tightening the fastening nut of the shock absorber 610, the clamping assembly 320 is first controlled to clamp the shock absorber 610. The driving member 331 is then controlled to drive the mounting seat 332 to move toward the clamping assembly 320, thereby driving the tightening gun 333 to move toward the clamping assembly 320 and causing the gun head of the tightening gun 333 to be positioned over the fastening nut. Finally, the tightening gun 333 is controlled to operate, and the tightening gun 333 drives the fastening nut to rotate, thereby tightening the fastening nut. After the fastening nut of the shock absorber 610 is tightened, the driving member 331 is first controlled to drive the mounting seat 332 to move away from the clamping assembly 320, thereby driving the tightening gun 333 to move away from the clamping assembly 320. The clamping assembly 320 is then controlled to release the shock absorber 610. At this point, the shock absorber 610 can be transferred by the transfer robot 100 to the brake disc 620 at the loading station 511. In a specific embodiment, the driving member 331 can be a driving cylinder or a driving oil cylinder, the structure of the tightening gun 333 can refer to the existing electric tightening gun 333, and the tightening gun 333 is provided with a tightening sleeve adapted to the fastening nut.

[0044] In this embodiment, the mounting seat 332 is slidably mounted on the mounting frame 310 via a slide rail and a slider. Specifically, there are two slide rails, spaced apart from each other on the mounting frame 310, and each slide rail is provided with two sliders. The mounting frame 310 is provided with a stop block 311 that can abut against the mounting seat 332. The stop block 311 is used to limit the position of the mounting seat 332. Specifically, when the driving member 331 drives the mounting seat 332 in a direction away from the clamping assembly 320, the stop block 311 can abut against the mounting seat 332 to limit the position of the mounting seat 332.

[0045] See also Figure 2 In one embodiment of the present invention, a positioning plate 323 is provided above the clamping block 322. The positioning plate 323 has a positioning slot 3231 for accommodating the shock absorber 610. Specifically, when the clamping assembly 320 clamps the shock absorber 610, it is first necessary to control the driving body 321 to drive the two clamping blocks 322 to move away from each other, thereby increasing the distance between the two clamping blocks 322 to provide sufficient space for the shock absorber 610 to be placed. Subsequently, the shock absorber 610 is placed between the two clamping blocks 322. When the shock absorber 610 is placed between the two clamping blocks 322, the shock absorber 610 is first placed in the positioning slot 3231 of the positioning plate 323. Finally, the driving body 321 is controlled to drive the two clamping blocks 322 to move toward each other, thereby clamping the shock absorber 610. The provision of the positioning slot 3231 enables the shock absorber 610 to be pre-positioned to ensure the accurate position of the shock absorber 610.

[0046] See also Figure 2 In one embodiment of the present invention, the tightening mechanism 300 further includes a locking assembly 340, which includes a positioning pin 341 and a locking unit 342. The locking unit 342 is formed with an avoidance groove 3421, in which the positioning pin 341 is received. The positioning pin 341 can be inserted into the mounting hole of the shock absorber 610. In this embodiment, the clamping assembly 320 is used to clamp the middle portion of the shock absorber 610, while the locking assembly 340 is used to clamp the end portion of the shock absorber 610. The cooperation between the clamping assembly 320 and the locking assembly 340 can better fix the position of the shock absorber 610. Specifically, the locking unit 342 is used to clamp the end portion of the shock absorber 610, while the positioning pin 341 can be inserted into the mounting hole at the end portion of the shock absorber 610 to prevent the shock absorber 610 from rotating. The avoidance groove 3421 is used for the positioning pin 341 to pass through to avoid interference between the positioning pin 341 and the locking unit 342. In a specific embodiment, the diameter of the positioning pin 341 is slightly smaller than the diameter of the mounting hole at the end of the shock absorber 610, and the difference between the two diameters is 0.1 mm.

[0047] See also Figure 2In one embodiment of the present invention, the locking unit 342 includes a driving unit 3422 and two locking blocks 3423 spaced apart from the driving unit 3422. The driving unit 3422 is mounted on the mounting frame 310 and is capable of driving the two locking blocks 3423 toward or away from each other. Each locking block 3423 is provided with an escape slot 3421. In this embodiment, the driving unit 3422 can drive the two locking blocks 3423 toward each other to clamp the ends of the shock absorber 610, and can also drive the two locking blocks 3423 away from each other to release the ends of the shock absorber 610. It should be noted that when the driving unit 3422 drives the two locking blocks 3423 to move toward or away from each other, clamping or loosening the end of the shock absorber 610, in order to ensure that the end of the shock absorber 610 can be placed between the two locking blocks 3423 and can be taken out from between the two locking blocks 3423, it is necessary to ensure that when the two locking blocks 3423 move to the farthest distance, the distance between the end of the positioning pin 341 passing through the avoidance groove 3421 and the locking block 3423 not penetrated by the positioning pin 341 is greater than the thickness of the end of the shock absorber 610; alternatively, the positioning pin 341 is designed to be a retractable structure, for example: by setting a telescopic cylinder to drive the positioning pin 341 to slide along its axial direction.

[0048] See also Figures 3 to 5 In one embodiment of the present invention, the carrying mechanism 200 includes a frame 210, a conveying assembly 220 and a carrying assembly 230. The conveying assembly 220 is arranged on the frame 210. The carrying assembly 230 includes a support plate 231 placed on the conveying assembly 220 and a positioning block 232 arranged on the support plate 231. The positioning block 232 is provided with a positioning hole for inserting the shock absorber 610. The frame 210 is provided with a driving cylinder 211; the carrying assembly 230 has a loading position and a recovery position. The conveying assembly 220 can drive the carrying assembly 230 to move along a first direction to the loading position; the driving cylinder 211 can drive the carrying assembly 230 to move along a second direction to switch between the loading position and the recovery position. Among them, the first direction refers to Figure 3 The second direction is the direction indicated by X in Figure 3 The direction indicated by Z in the figure. Specifically, the conveying assembly 220 is provided on the frame 210, and can drive the carrying assembly 230 placed thereon to move along a first direction to transport the carrying assembly 230 to the loading position. The carrying assembly 230 includes a pallet 231 and a positioning block 232. The pallet 231 is placed on the conveying assembly 220, and the positioning block 232 is used to place the shock absorber 610. By providing a positioning hole for inserting the shock absorber 610 on the positioning block 232, the shock absorber 610 can be positioned and fixed, thereby preventing the shock absorber 610 from shaking during the conveying process, so that the transfer robot 100 can grasp the shock absorber 610.

[0049] In a specific embodiment, there are multiple positioning blocks 232, and the multiple positioning blocks 232 are arranged in a rectangular array on the support plate 231. By arranging the multiple positioning blocks 232 in a rectangular array on the support plate 231, the number of shock absorbers 610 that can be placed on the carrier assembly 230 can be increased, the transportation efficiency can be improved, and the assembly efficiency can be improved. Each positioning block 232 is provided with two positioning rods 233 spaced apart along the second direction. A clamping gap for inserting the shock absorber 610 is provided between the two positioning rods 233 of each positioning block 232. A reinforcing rod 234 is provided between the two positioning rods 233 of two adjacent positioning blocks 232 that are close to each other along the third direction. The third direction is Figure 4 The direction indicated by Y in FIG. When placing the shock absorber 610 on the carrier assembly 230, the shock absorber 610 needs to first pass through the clamping gap between the two positioning rods 233 and then be inserted into the positioning hole. The two positioning rods 233 can both abut against the outer side surface of the shock absorber 610 to limit the position of the shock absorber 610 in the third direction, thereby ensuring the accurate positioning of the shock absorber 610. In this embodiment, the positioning hole has two first positioning surfaces arranged opposite to each other along the first direction, and the end of the shock absorber 610 inserted into the positioning hole has two second positioning surfaces arranged opposite to each other, wherein the first positioning surface and the second positioning surface are both flat. When the shock absorber 610 is inserted into the positioning hole, the two first positioning surfaces correspond to the two second positioning surfaces in a one-to-one manner, thereby fixing the position of the shock absorber 610 in the first direction and preventing the shock absorber 610 from shaking in the first direction. Through the cooperation between the positioning rods 233 and the positioning hole, the shock absorber 610 can be positioned and fixed to prevent the shock absorber 610 from shaking in the first and third directions. Guide wheels are provided on both sides of the conveyor assembly 220, and these wheels can abut against positioning blocks 232. Specifically, when the conveyor assembly 220 drives the carrier assembly 230 to move in the first direction, the guide wheels can abut against the positioning blocks 232 to limit the position of the carrier assembly 230, thereby ensuring the accurate positioning of the carrier assembly 230 during movement in the first direction. In one specific embodiment, the guide wheels on both sides respectively abut against two positioning blocks 232 at the ends along the third direction; the guide wheels are rotatably mounted on the frame 210.

[0050] See also Figure 3In one embodiment of the present invention, the conveying assembly 220 includes a first conveying unit 221 and a second conveying unit 222. The second conveying unit 222 is arranged on one side of the first conveying unit 221 along the first direction, and the second conveying unit 222 is slidably arranged on the frame 210 along the second direction. The first conveying unit 221 and the second conveying unit 222 can both drive the supporting assembly 230 to move along the first direction; when the supporting assembly 230 is in the loading position, the supporting assembly 230 is placed on the second conveying unit 222; the driving cylinder 211 can drive the second conveying unit 222 to move along the second direction to drive the supporting assembly 230 to switch between the loading position and the recovery position. Driven by the first conveying unit 221 and the second conveying unit 222, the carrier assembly 230 can move in a first direction to a loading position. After the transfer robot 100 has grasped the shock absorber 610 on the carrier assembly 230, the drive cylinder 211 can drive the second conveying unit 222 to move in a second direction, thereby driving the carrier assembly 230 from the loading position to the recovery position. The second conveying unit 222 can then drive the carrier assembly 230 in a direction opposite to the first direction to move the emptied carrier assembly 230 out of the recovery position, thereby recovering the emptied carrier assembly 230. By slidably arranging the second conveying unit 222 on the frame 210 in the second direction and providing a drive member 331 capable of driving the second conveying unit 222, the emptied carrier assembly 230 can be recovered, thereby improving work efficiency.

[0051] See also Figure 4 In one embodiment of the present invention, the first conveying unit 221 includes a first drive motor 2211 and a plurality of first rollers 2212 spaced apart along a first direction.

In a specific embodiment, each first roller 2212 is provided with a first synchronous wheel and a second synchronous wheel at intervals, wherein, to be explained in the opposite direction of the first direction, the first synchronous wheel of the first first roller 2212 and the first synchronous wheel of the second second roller are connected by a synchronous belt, the second synchronous wheel of the second first roller 2212 and the second synchronous wheel of the third first roller 2212 are connected by a synchronous belt, the first synchronous wheel of the third third roller 241 and the first synchronous wheel of the fourth first roller 2212 are connected by a synchronous belt, and then the above connection method is repeated to realize the transmission connection of any two adjacent first rollers 2212.

[0052] The second conveying unit 222 includes a mounting seat 332 and a plurality of second rollers spaced apart along the first direction. Each second roller is rotatably mounted on the mounting seat 332 , and a second driving motor is disposed inside each second roller. When the carrying assembly 230 needs to move to the loading position, first, the first conveying unit 221 conveys the carrying assembly 230 along the first direction until a part of the carrying assembly 230 overlaps the second roller of the second conveying unit 222 closest to the first conveying unit 221, and then each second driving motor drives the corresponding second roller to rotate forward at the same time. At this time, the carrying assembly 230 will move to the loading position under the common drive of the first conveying unit 221 and the second conveying unit 222; after the shock absorber 610 on the carrying assembly 230 has completed the grabbing, the driving cylinder 211 drives the second conveying unit 222 to move along the third direction, so that the carrying assembly 230 moves from the loading position to the recovery position; after the emptied carrying assembly 230 moves to the recovery position, each second driving motor drives the corresponding second roller to rotate in the opposite direction at the same time. At this time, the emptied carrying assembly 230 will be driven out of the recovery position by the second conveying unit 222, and then the emptied carrying assembly 230 will be recovered.

[0053] See also Figure 3 and Figure 4 In one embodiment of the present invention, the carrier mechanism 200 further includes a recovery assembly 240. The recovery assembly 240 is disposed above the conveyor assembly 220 and located to one side of the recovery position. The recovery assembly 240 is inclined along a first direction from a side closer to the first conveyor unit 221 to a side farther away from the first conveyor unit 221. When an empty carrier assembly 230 is in the recovery position, the empty carrier assembly 230 is driven by the second conveyor unit 222 to move out of the recovery position and onto the recovery assembly 240. Subsequently, under the action of its own weight, the empty carrier assembly 230 slides downward along the recovery assembly 240 to the bottom of the recovery assembly 240. At this point, a worker can recover the empty carrier assembly 230.

[0054] In one specific embodiment, the recovery assembly 240 includes a plurality of third rollers 241 spaced apart along the first direction. Each third roller 241 is rotatably mounted on the frame 210. Specifically, as the emptied carrier assembly 230 slides downward along the recovery assembly 240, it rolls on the third rollers 241. The provision of the third rollers 241 reduces resistance to the downward sliding of the emptied carrier assembly 230, thereby ensuring that the emptied carrier assembly 230 can slide downward along the recovery assembly 240 to the bottom of the recovery assembly 240. In this embodiment, the plurality of third rollers 241 are sequentially raised along the first direction.
