Technical Field
[0001] This invention relates to the field of loading and unloading equipment technology, specifically to a cargo loading and unloading device for automobile parts. Background Technology
[0002] With the rapid development of the automotive industry, the demand for transportation and loading / unloading of automotive parts has increased significantly. Automotive parts are diverse, including heavy components such as engine blocks as well as fragile precision parts such as dashboard housings. The stability and safety requirements for the loading and unloading process are extremely high, especially to avoid damage from impacts during loading and unloading.
[0003] Currently, the loading and unloading of automotive parts mostly relies on traditional methods involving manual labor in conjunction with forklifts and stackers. This is not only inefficient, but manual operation is also prone to collisions and damage caused by improper angle adjustment and inaccurate center of gravity control. Some automated loading and unloading equipment lacks effective anti-collision structures, and the robotic arm is prone to hard collisions with the vehicle, shelves, or the parts themselves during the grabbing or lifting process, resulting in deformation and surface scratches. Although some equipment attempts to incorporate buffer structures, their adaptability is poor, and they cannot adjust the buffering force according to automotive parts of different weights and shapes, still posing a risk of impact. Furthermore, it is difficult to achieve fully automated loading and unloading, requiring manual intervention, which cannot meet the needs of large-scale production. Summary of the Invention

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0033] Example 1: This embodiment provides a cargo loading and unloading device for automotive parts, which has the following technical features.
[0034] Please see Figures 1-5 , Figure 7 As shown, it includes a hydraulic lifting conveyor belt 1 and an omnidirectional moving chassis 2. The omnidirectional moving chassis 2 is located at the bottom of the hydraulic lifting conveyor belt 1. A telescopic conveyor 3 is provided at one end of the hydraulic lifting conveyor belt 1. A tensioning component 5 is slidably installed on the top of the telescopic conveyor 3. A rotation guide component 4 is rotatably installed on the side of the telescopic conveyor 3. Specifically, the hydraulic lifting conveyor belt 1 serves as a power drive unit. Utilizing its frame extension and lifting action, it directly lifts the telescopic conveyor 3 through mechanical structures such as connecting rods, hinged brackets, wire ropes, and jacking brackets, enabling the telescopic conveyor 3 to unload goods at different heights. The omnidirectional mobile chassis 2 uses Mecanum wheels and achieves longitudinal and lateral movement through independent drive control, enabling the unloading of goods at different positions.
[0035] like Figure 3 and Figure 4 As shown, the rotating guide assembly 4 includes a rotating frame 41. A fixed rod 42 is fixedly connected to one end of the rotating frame 41 near the telescopic conveyor 3. A fixed sprocket 43 is fixedly sleeved on the outer surface of the middle part of the fixed rod 42. Electric rails 44 are fixedly connected to both ends of the top of the rotating frame 41. A magnet block 45 is fixedly connected to one end of the electric rail 44 near the telescopic conveyor 3. An auxiliary roller assembly 46 is fixedly connected to one end of the rotating frame 41 away from the fixed rod 42. The auxiliary roller assembly 46 rotates continuously in the direction of the rotating frame 41 and assists in pushing the goods to the top of the rotating frame 41. The rotating frame 41 is fixedly connected to support components 410 on both sides to support the goods on both sides and prevent the goods on both sides from tipping over during the pulling process.
[0036] The bottom of the rotating frame 41 is fixedly connected to a servo driver 47 via a bracket. Both ends of the rotating frame 41 are fixedly connected to a track motor 48. The servo driver 47 is electrically connected to the track motors 48 at both ends. The track motors 48 are connected to the electric track 44. A roller motor 49 is fixedly connected to the end of the rotating frame 41 away from the telescopic conveyor 3. A fixed plate is fixedly connected to the upper end of the rotating frame 41.
[0037] Specifically, the electric track 44 is equipped with a transmission belt inside, and one end of the transmission belt is connected to the sliding sleeve. When the servo driver 47 controls the track motors 48 at both ends to work synchronously, the transmission belt is transported inside the electric track 44 and drives the sliding sleeve to move through the track motors 48. In addition, the electric track 44 is provided with limit grooves on both sides so that the sliding sleeves at both ends can move stably on the outer surface of the electric track 44 on both sides.
[0038] like Figure 5 As shown, the auxiliary roller assembly 46 includes a side frame 461, with support rods rotatably mounted at both ends of the side frame 461. Friction rollers 462 are fixedly sleeved on the outer surfaces of both sides of the support rods. One end of the support rods is connected to the other end via a chain drive 463. The diameter of the friction roller 462 at the end closer to the rotating frame 41 is larger than the outer surface of the friction roller 462 at the other end. A linkage sprocket 464 is fixedly sleeved on the outer surface of the middle of the support rod at the end closer to the rotating frame 41. The linkage sprocket 464 is connected to the roller motor 49 via a transmission chain. Friction protrusions are provided on the outer surfaces of both friction rollers 462 to increase the friction between the friction rollers 462 and the goods, facilitating the pushing of the goods.
[0039] Specifically, the roller motor 49 controls the rotation of one of the support rods through the transmission chain, which drives the friction roller 462 to rotate. Through the action of the chain transmission component 463, the friction rollers 462 at both ends rotate synchronously to assist in pushing the goods.
[0040] like Figure 7As shown, the tensioning assembly 5 includes a fixed frame 51. A camera with lighting function is fixedly connected to the top of the fixed frame 51 for remote viewing and control. Hydraulic lifting rods 52 are fixedly connected to both ends of the bottom of the fixed frame 51, and sliding sleeves are fixedly connected to the bottom of both hydraulic lifting rods 52. The hydraulic lifting rods 52 are connected to the electric rail 44 through the movable sleeves. A synchronous controller 53 is fixedly connected to one end of the top of the fixed frame 51, and the synchronous controller 53 is electrically connected to the hydraulic lifting rods 52 at both ends. A limiting frame is set inside the fixed frame 51, and a moving plate 54 is slidably sleeved on the outer surface of the limiting frame. Multiple trumpet-shaped fixed sleeves 56 are fixedly connected to the side of the fixed frame 51 away from the synchronous controller 53. Multiple pull ropes 57 are fixedly connected to one side of the moving plate 54. The multiple pull ropes 57 are movably sleeved inside the multiple fixed sleeves 56, and a connecting frame 55 is fixedly connected to one end of the multiple pull ropes 57.
[0041] The connecting frame 55 has multiple connected, pointed insert rods on the side near the pull rope 57, which are fitted with a trumpet-shaped fixing sleeve 56 so that the insert rods can be smoothly inserted into the inside of the fixing sleeve 56 during the resetting process of the connecting frame 55. Multiple universal swing vacuum suction cups 59 are fixedly connected to the end of the connecting frame 55 away from the fixing frame 51. A damper 510 is provided between the moving plate 54 and the inner wall of the fixing frame 51 near the synchronous controller 53 to prevent the moving plate 54 from moving quickly during the tilting of the goods, causing the goods to vibrate, and to prevent the universal swing vacuum suction cups 59 from falling off due to rapid pulling between them and the goods. A reset spring 58 is movably sleeved on the outer surface of the pull rope 57. The reset spring 58 is located between the inner side of the fixing frame 51 and the moving plate 54.
[0042] Example 2: This embodiment provides a cargo loading and unloading device for automobile parts, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0043] like Figures 8-9 As shown, the telescopic conveyor 3 includes a fixed frame 31, with hydraulic lifting feet 32 at each of the four corners of the fixed frame 31. Electromagnets 33 are fixedly connected to both ends of the top of the fixed frame 31. A movable support 36 is movably sleeved at the end of the fixed frame 31 near the rotating guide assembly 4. A bottom frame 37 is fixedly connected to the bottom of the end of the movable support 36 away from the fixed frame 31. A steering motor 38 is fixedly connected inside the bottom frame 37. A transmission sprocket is fixedly connected to the output end of the steering motor 38. The transmission sprocket is connected to the fixed sprocket 43 through a rotating chain. A fixed rod 42 is rotatably installed at the end of the movable support 36 away from the fixed frame 31.
[0044] In this system, the hydraulic lifting conveyor belt 1 lifts the telescopic conveyor 3, and the hydraulic lifting legs 32 extend and support the inside of the cargo box, thereby controlling the height of the telescopic conveyor 3.
[0045] Among them, a drive cylinder 34 is fixedly connected to one end of the bottom of the fixed frame 31, and a movable frame 35 is fixedly connected to the output end of the drive cylinder 34. The movable frame 35 is fixedly connected to the end of the movable support 36 near the fixed frame 31, and a conveyor belt 39 is sleeved on the outer surface of the fixed frame 31 and the movable support 36.
[0046] like Figure 9 As shown, drive belt rollers are provided at the upper and lower ends of the right side and the lower end of the left side of the fixed frame 31. A conveyor motor is provided on one side of the fixed frame 31 and is connected to one of the drive belt rollers. Drive belt rollers are also provided at the upper end of the left side and the lower end of the right side of the movable support frame 36. The conveyor belt 39 is sleeved on the outer surface of these drive belt rollers. When the conveyor motor controls the drive belt rollers to rotate, the conveyor belt 39 conveys. When the drive cylinder 34 controls the movable frame 35 to move at the bottom of the fixed frame 31, it pushes the movable support frame 36 to move inside the fixed frame 31. At this time, the drive belt rollers at both ends of the movable support frame 36 support the conveyor belt 39 and push the conveyor belt 39 to move to the left, realizing the extension and retraction of the conveyor belt.
[0047] One end of the rotating frame 41 is rotatably mounted on the fixed frame 31 at the end away from the hydraulic lifting conveyor belt 1, one end of the electric track 44 is located on the top of the fixed frame 31, and the magnet block 45 is magnetically connected to the electromagnet 33.
[0048] Specifically, when the rotating guide assembly 4 needs to tilt and rotate, the electromagnet 33 stops working. During the rotation of the rotating frame 41, the electric track 44 is driven to rotate. When the rotating frame 41 rotates to a state where it is horizontal with the fixed frame 31, the electric track 44 stops at the top of the fixed frame 31. At this time, the electromagnet 33 works and magnetically attracts the magnet block 45, thereby fixing the electric track 44 to the fixed frame 31. This causes the stretching assembly 5 to move to the top of the fixed frame 31 and pulls the goods onto the conveyor belt 39.
[0049] Example 3: This embodiment provides a cargo loading and unloading device for automobile parts, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0050] like Figure 6As shown, the support assembly 410 includes a side box 411 with a communicating cavity at one end. A push cylinder 412 is fixedly connected to one end inside the side box 411. A central support block 413 with vertical grooves on both the upper and lower sides is fixedly connected to the output end of the push cylinder 412. Support arms 414 are rotatably mounted on both the upper and lower ends of the central support block 413 to ensure that the support arms 414 are in a vertical state after rotation. The central support block 413 is slidably installed in the communicating cavity inside the side box 411. A side support block 415 is fixedly connected to the opposite side of the upper and lower support arms 414 away from the central support block 413. The end of the support arm 414 away from the central support block 413 is arc-shaped so that the support arms 414 at both ends rotate upward and downward when they come into contact with the goods.
[0051] Working principle: In summary, when the cargo loading and unloading equipment for automobile parts is in operation, the hydraulic lifting conveyor belt 1 serves as the power drive unit. Utilizing its frame extension and lifting action, it directly lifts the telescopic conveyor 3, causing the telescopic conveyor 3 to move into the cargo compartment. At this time, the hydraulic lifting support leg 32 extends and supports the cargo compartment, completing the fixation. Subsequently, the drive cylinder 34 operates, causing the moving frame 35 to drive the moving support 36 to extend, allowing the moving support 36 to move out of the fixed frame 31. At this time, the moving support 36 drives the rotating guide assembly 4 into the cargo compartment, and causes the rotating frame 41 to move into the bottom of the goods to be unloaded, thereby enabling the device to penetrate deep into the cargo compartment and complete the loading and unloading of goods from a greater distance. When loading and unloading goods at the top of the cargo, such as Figure 10 As shown, the servo drive 47 controls the track motors 48 at both ends to work, causing the hydraulic lifting rod 52 to move towards the cargo from the top of the electric track 44. The roller motor 49 controls the friction roller 462 to rotate. In addition, the push cylinder 412 controls the middle support block 413 to move out of the side box 411. The middle support block 413 and the support arms 414 at both ends press against the cargo on both sides and spread out to both sides. Finally, the side support block 415 and the middle support block 413 press against the side of the cargo next to them, providing auxiliary support for both sides of the cargo to be unloaded, and preventing the cargo on both sides from falling when the cargo is unloaded. When the universal swing vacuum suction cup 59 moves to the side of the cargo, the universal swing vacuum suction cup 59 works to suction the cargo. Then, the hydraulic lifting rod 52 moves towards the telescopic conveyor 3 and pulls the cargo to move, so that the cargo moves into the top of the fixed plate of the rotating frame 41 and into the top of the conveyor belt 39, and is transported onto the hydraulic lifting conveyor belt 1 for downward transmission, thus realizing unloading.
[0052] In addition, when loading and unloading goods at the bottom of the carriage, such as Figure 11As shown, the steering motor 38 controls the fixed sprocket 43 to rotate, which in turn drives the rotating frame 41 to rotate via the fixed rod 42, causing the rotating frame 41 to tilt to the bottom of the carriage. When the omnidirectional swing vacuum suction cup 59 moves to the side of the cargo, it operates to suction the cargo. Subsequently, the hydraulic lifting rod 52 moves towards the telescopic conveyor 3 and pulls the cargo. At this time, when the cargo moves to the side of the friction roller 462, it will tilt towards the telescopic conveyor 3. Due to gravity, the cargo will cause the connecting frame 55 to pull the pull rope 57, compressing the return spring 58. Through the action of the damper 510, the cargo will slowly tilt, and finally, through the stretching action of the pull rope 57, the cargo will remain tilted. As the hydraulic lifting rod 52 moves, the stretching component 5 pulls the cargo. At the same time, the friction roller 462 rotates and, through friction, assists in pushing the cargo upward. The cargo enters the top of the fixed plate of the rotating frame 41, and then the steering... Motor 38 controls the rotating frame 41 to rotate until it is flush with the fixed frame 31. At this time, the electric track 44 moves to the top of the fixed frame 31 as the rotating frame 41 rotates. The magnet block 45 is magnetically attracted and fixed to the electromagnet 33. The stretching component 5 pulls the goods to the top of the conveyor belt 39. The synchronous controller 53 controls the hydraulic lifting rod 52 to extend, causing the fixed frame 51 to move one end of the pull rope 57 upward, and cooperating with the conveyor belt 39 to move the goods. The pull rope 57 straightens the goods. Then, the universal swing vacuum suction cup 59 stops working, the reset spring 58 resets, and pulls the connecting frame 55 upward, so that the moving plate 54 inserts the connecting frame 55 into the side of the fixed sleeve 56 through the pull rope 57. At this time, the goods are transported to the hydraulic lifting conveyor belt 1 through the lower end of the fixed frame 51 for downward transmission. By rotating the guide component 4 and cooperating with the friction roller 462, the height difference of the telescopic conveyor 3 is compensated, realizing the loading and unloading of goods at the bottom of the carriage.
