Description

Technical Field

[0001] This utility model relates to the field of vehicle parts conveying technology, and in particular to a conveyor line transfer elevator for vehicle parts. Background Technology

[0002] In the production and assembly of vehicle parts, the conveying process is crucial. Traditional conveying methods often suffer from insufficient flexibility and inaccurate docking, making it difficult to meet the demands of modern production for efficient and stable conveying. Especially when transferring parts between different workstations, differences in the height, direction, and spacing of various conveying devices often lead to jams and drops during the conveying process, which not only affects production efficiency but may also damage the parts.

[0003] While some similar conveying equipment exists on the market, most offer only a single function and cannot simultaneously perform multiple tasks such as height adjustment, directional rotation, and precise docking. Some devices, although equipped with lifting capabilities, suffer from poor stability during lifting and are prone to swaying. Others, lacking effective support and limiting mechanisms, experience uneven rotation during the rotating transmission mechanism, potentially leading to safety accidents. Furthermore, significant gaps can occur when docking with other conveying devices, causing transmission instability. In addition, the level of automation in existing equipment needs improvement, with many operations still requiring manual intervention, increasing labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a transfer elevator for vehicle parts conveying lines, which solves the problems of single function, insufficient flexibility, large docking distance and poor stability of existing vehicle parts lifting and conveying equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A conveyor transfer lift for vehicle parts includes a gantry frame. A lifting cylinder is fixedly installed on the top of the gantry frame, and the lifting cylinder drives an L-shaped lifting frame to move up and down. A rotatable transmission mechanism is installed on the lifting frame via a rotating mechanism. A telescopic transmission mechanism is installed at the end of the transmission mechanism. The transmission mechanism includes a transmission base plate, transmission side plates, and fixed electric rollers. The transmission base plate is installed on the top of the rotating mechanism. Transmission side plates are vertically fixed on both sides of the transmission base plate. Multiple equidistant fixed electric rollers are installed between two transmission side plates. The telescopic transmission mechanism includes a fixed seat, a guide cylinder, a telescopic shaft, a U-shaped frame, a movable electric roller, and a telescopic cylinder. Each transmission side plate is equipped with at least two fixed seats. A guide cylinder is horizontally fixed on the fixed seat. A telescopic shaft is slidably connected inside the guide cylinder. The outer ends of the two telescopic shafts are fixedly connected to the U-shaped frame. A movable electric roller is rotatably installed inside the U-shaped frame. The movable electric roller is parallel to the fixed electric roller. A telescopic cylinder is fixedly installed on the transmission base plate. The output end of the telescopic cylinder is fixedly connected to the U-shaped frame via a connecting seat.

[0006] Preferably, a proximity switch is fixedly installed on the side of the transmission side plate away from the telescopic transmission mechanism. There are two proximity switches, each symmetrically installed on the two transmission side plates.

[0007] Preferably, the rotating mechanism includes a worm gear reducer, a central shaft, support devices, and an angle limiting mechanism. The worm gear reducer is fixedly installed on the lifting frame, and a vertical central shaft is fixedly installed at its output end. The top of the central shaft is fixedly installed at the center of the transmission base plate. Multiple support devices are arranged radially around the central shaft and fixed on the lifting frame. The rotation angle of the transmission base plate is limited by the angle limiting mechanism.

[0008] Preferably, the support device includes a support cylinder, a nut, a screw, and a universal ball. The support cylinder is fixed to the lifting frame, a nut is fixed to the top of the support cylinder, the screw is threadedly engaged with the nut, and a universal ball is fixed to the top of the screw.

[0009] Preferably, the angle limiting mechanism includes a proximity switch B and a blocking block. The proximity switch B is fixed to the lifting frame by a bracket, and there are two blocking blocks, which are respectively fixed to the bottom surface of the transmission base plate.

[0010] Preferably, the lifting frame includes a connecting plate and a linear guide rail pair. The connecting plate is fixed to the vertical end of one side of the lifting frame. The bottom output end of the lifting cylinder is fixed to the connecting plate. The vertical end of one side of the lifting frame is slidably connected to the vertical end of one side of the gantry frame through two vertical linear guide rail pairs.

[0011] Preferably, the lifting frame further includes a reflector and a diffuse infrared sensor. The reflector is fixed to the vertical end of one side of the lifting frame, and the two diffuse infrared sensors are distributed vertically on the same side of the gantry frame as the reflector.

[0012] This utility model has the following beneficial effects: 1. By setting up a lifting cylinder to drive the lifting frame to move up and down, the height of the transmission mechanism can be adjusted flexibly and smoothly. The rotating mechanism allows the transmission mechanism to be rotated and adjusted, which is convenient for adjusting the transmission direction of the parts.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1-3 As shown, in this embodiment, a vehicle parts conveyor transfer lift includes a gantry frame 1. A lifting cylinder 2 is bolted to the top of the gantry frame 1. The lifting cylinder 2 drives an L-shaped lifting frame 3 to move up and down. A rotatable transmission mechanism 5 is mounted on the lifting frame 3 via a rotating mechanism 4. The transmission mechanism 5 is used to transport vehicle parts. A telescopic transmission mechanism 6 is installed at the end of the transmission mechanism 5 for connecting to other transmission devices. The transmission mechanism 5 includes a transmission base plate 51, transmission side plates 52, and fixed electric rollers 53. The transmission base plate 51 is mounted on the top of the rotating mechanism 4. Transmission side plates 52 are vertically fixed on both sides of the transmission base plate 51. Multiple equidistant fixed electric rollers 53 are installed between two transmission side plates 52. The telescopic transmission mechanism 6 includes a fixed base 61. The system includes a guide cylinder 62, a telescopic shaft 63, a U-shaped frame 64, a movable electric roller 65, and a telescopic cylinder 66. Each of the transmission side plates 52 is equipped with at least two fixed seats 61. The guide cylinder 62 is horizontally fixed on the fixed seat 61. The guide cylinder 62 is a linear bearing. The telescopic shaft 63 is slidably connected inside the guide cylinder 62. The outer ends of the two telescopic shafts 63 are fixedly connected to the U-shaped frame 64 through an optical axis support frame. The movable electric roller 65 is rotatably installed inside the U-shaped frame 64. The movable electric roller 65 is parallel to the fixed electric roller 53. The telescopic cylinder 66 is fixedly installed on the transmission base plate 51. The output end of the telescopic cylinder 66 is fixedly connected to the U-shaped frame 64 through a connecting seat. It drives the telescopic shaft 63 to slide along the guide cylinder 62, thereby causing the movable electric roller 65 to extend or retract, so as to achieve precise docking with other transmission devices. The fixed electric roller 53 and the movable electric roller 65 are identical, with built-in motors electrically connected to the distribution box. The distribution box is equipped with a PLC system. Multiple fixed electric rollers 53 and movable electric rollers 65 are driven by motors to achieve synchronous rotation, so as to ensure the stability of vehicle parts during the transmission process.

[0019] Specifically, the lifting cylinder 2 can drive the lifting frame 3 to move up and down, thereby adjusting the height of the transmission mechanism 5 to adapt to the transmission needs of different workstations. The rotation mechanism 4 can realize the rotation adjustment of the transmission mechanism 5, which facilitates the adjustment of the transmission direction of parts. When it is necessary to connect with other transmission devices, the telescopic cylinder 66 drives the U-shaped frame 64 to extend outward, and the moving electric roller 65 shortens the distance with other transmission devices, avoiding transmission instability caused by distance differences. By retracting the moving electric roller 65, it is ensured that the telescopic transmission mechanism 6 does not interfere with other transmission devices when the transmission mechanism 5 is rotating.

[0020] like Figure 3 As shown, a proximity switch 54 is fixedly installed on the side of the transmission side plate 52 away from the telescopic transmission mechanism 6. There are two proximity switches 54, each symmetrically installed on the two transmission side plates 52. The proximity switches 54 are connected to the PLC system signal.

[0021] Specifically, when a vehicle component moves into the detection area of ​​proximity switch 54, if both proximity switches 54 simultaneously detect the component's presence, the PLC system determines this as a valid signal, triggering the telescopic cylinder 66 to extend the moving electric roller 65 outward, seamlessly connecting it with the adjacent conveying device. This effectively improves the automation level of the equipment, reduces manual intervention, and enhances conveying efficiency. Furthermore, the symmetrically arranged dual proximity switches 54 form a redundant detection mechanism, avoiding misoperation caused by single-point failures, thereby further ensuring the safety and reliability of the conveying process. Through centralized control of the PLC system, coordinated linkage between various actuators is achieved, significantly improving the intelligence level of the vehicle component conveying process.

[0022] like Figure 4 As shown, the rotating mechanism 4 includes a worm gear reducer 41, a central shaft 42, a support device 43, and an angle limiting mechanism. The worm gear reducer 41 is electrically connected to the distribution box and is fixedly installed on the lifting frame 3. The output end is fixedly connected to the vertical central shaft 42 via a key. The top of the central shaft 42 is fixedly installed at the center of the transmission base plate 51 to realize the overall rotation adjustment of the transmission mechanism 5. Multiple support devices 43 are arranged radially around the central shaft 42 and fixed on the lifting frame 3 for supporting the transmission base plate 51. The rotation angle of the transmission base plate 51 is limited by the angle limiting mechanism to ensure that the rotation angle is within the set range.

[0023] like Figure 5As shown, the support device 43 includes a support cylinder 431, a nut 432, a screw 433, and a universal ball 444. The support cylinder 431 is bolted to the lifting frame 3. The nut 432 is welded to the top of the support cylinder 431. The screw 433 is threaded to the nut 432. The universal ball 444 is welded to the top of the screw 433 and supports the bottom surface of the transmission base plate 51. The contact part between the universal ball 444 and the bottom surface of the transmission base plate 51 is a smooth structure.

[0024] Specifically, the threaded engagement of screw 433 and nut 432 allows for precise adjustment of the screw 433's height, thereby adjusting the support height of the universal ball 444 to ensure it can support the bottom surface of the transmission base plate 51. The smooth structural design of the universal ball 444, in contact with the bottom surface of the transmission base plate 51, effectively reduces frictional resistance during rotation, making the rotation adjustment of the transmission mechanism 5 smoother and more stable. Simultaneously, this support method also possesses good load-bearing capacity, ensuring the structural stability of the transmission mechanism 5 when transporting vehicle components.

[0025] like Figure 4 As shown, the angle limiting mechanism includes a proximity switch B44 and a blocking block 45. The proximity switch B44 is fixed to the lifting frame 3 by a bracket. There are two blocking blocks 45, which are connected to the PLC system signal and are fixed to the bottom surface of the transmission base plate 51 respectively. They are distributed around the central axis 42, and the position angle can be set according to the actual rotation angle of the transmission mechanism 5.

[0026] Specifically, when the transmission base plate 51 rotates to a certain angle, the blocking block 45 approaches the proximity switch B44. Upon detecting the blocking block 45, the proximity switch B44 sends a signal to the PLC system. The PLC system then controls the rotating mechanism 4 to stop rotating according to a preset program, thereby limiting the rotation angle of the transmission mechanism 5 within a set range. This prevents collisions with other components or loss of control over the transmission direction due to excessive rotation, ensuring the safety and stability of the equipment operation. The cooperation between the proximity switch B44 and the blocking block 45 accurately achieves the angle limiting function, facilitating installation and maintenance.

[0027] like Figure 6 As shown, the lifting frame 3 includes a connecting plate 31 and a linear guide rail pair 32. The connecting plate 31 is bolted to the vertical end of one side of the lifting frame 3. The bottom output end of the lifting cylinder 2 is bolted to the connecting plate 31. The vertical end of one side of the lifting frame 3 is slidably connected to the vertical end of one side of the gantry frame 1 through two vertical linear guide rail pairs 32.

[0028] Specifically, the linear guide pair 32 consists of a guide rail and a slider. The guide rail is fixedly installed on the gantry frame 1, and the slider is fixedly connected to the lifting frame 3, ensuring that the lifting frame 3 can move smoothly and accurately up and down in a straight line along the linear guide pair 32 under the drive of the lifting cylinder 2. At the same time, the linear guide pair 32 ensures the stability of the lifting frame 3 during long-term operation.

[0029] like Figure 1 As shown, the lifting frame 3 also includes a reflector 33 and a diffuse infrared sensor 34. The reflector 33 is fixed on the vertical end of one side of the lifting frame 3. The two diffuse infrared sensors 34 are distributed vertically and located on the gantry 1 on the same side of the reflector 33, and are connected to the PLC system signal.

[0030] Specifically, when the lifting frame 3 moves up and down under the drive of the lifting cylinder 2, the reflector 33 moves synchronously. The diffuse infrared sensor 34 continuously emits infrared light and detects the reflected signal. When the reflector 33 moves into the detection range of the diffuse infrared sensor 34, the sensor receives the reflected signal and sends position information to the PLC system. The PLC system determines the current height of the lifting frame 3 according to a preset program, realizing precise monitoring and control of the lifting position. This design effectively avoids equipment failure caused by the lifting frame 3 exceeding its travel range.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
