Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts transfer and hanging devices, in particular to a follow-up transfer and hanging device. Background Art

[0002] The follow-up transfer and hanging device is used to achieve the continuous conveying of workpieces by chain plates without affecting the transfer and hanging action of the workpieces. Here, the workpieces generally refer to vehicle bodies, interior trim parts, chassis, car doors, etc., and the workpieces complete subsequent assembly work through the follow-up transfer and hanging device.

[0003] There are two traditional ways of workpiece follow-up transfer and hanging in the automotive industry. The first is that the elevator directly transfers and hangs to the designated position, that is, the elevator equipped with the workpiece stops at the waiting position. After the plate chain transports to the designated position, the elevator descends directly to the designated position with the workpiece. The swing arm of the elevator retracts to make the workpiece fall onto the plate chain, thus completing the workpiece transfer and hanging action. The second is to use a common follow-up transfer and hanging device, that is, the elevator transfers the workpiece to the follow-up device. The follow-up device runs to a fixed position. After waiting for the plate chain to transport to the designated position, the follow-up device equipped with the workpiece immediately descends to the designated position. At the same time, the swing arm of the transfer and hanging device retracts, and the workpiece falls onto the plate chain, thus completing the workpiece transfer and hanging action.

[0004] The above two workpiece transfer and hanging methods can only be applied to the working conditions of low-beat production lines, with low production efficiency and high failure rates. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a follow-up transfer and hanging device, which can solve the technical problems that the existing follow-up transfer and hanging device cannot be applied to the working conditions of high-beat production lines, has a high failure rate and low production efficiency.

[0006] To achieve the above purpose, a follow-up transfer and hanging device designed by the utility model includes an installation track, an installation frame, a follow-up mechanism, a lifting mechanism, and a telescopic mechanism. The follow-up mechanism is located above the installation track and is slidably connected to the installation track. The installation frame is connected to the follow-up mechanism. The lifting mechanism is arranged above the installation frame, and the telescopic mechanism is arranged above the lifting mechanism.

[0007] As a preferred solution, the follow-up mechanism includes a walking vehicle body assembly and a follow-up motor. The walking vehicle body assembly is connected to the installation frame, and the follow-up motor is arranged inside the walking vehicle body assembly. The follow-up mechanism drives the whole device to move back and forth along the length direction of the plate chain.

[0008] Preferably, the walking vehicle body assembly is a hollow boxed structure, and the follow-up motor is arranged in the boxed cavity. The hollow boxed structure can reduce the occupied volume of the walking vehicle body assembly.

[0009] As a preferred solution, the lifting mechanism includes a lifting motor, a lifting universal shaft, and a vehicle frame assembly. The lifting motor is arranged on the mounting frame. The driving shaft of the lifting motor is connected to the end of the lifting universal shaft. The vehicle frame assembly is connected to the side of the lifting universal shaft. The lifting mechanism drives the telescopic mechanism and the vehicle body to lift together, ensuring that the vehicle body is accurately transferred and hung on the plate chain.

[0010] Preferably, the vehicle frame assembly is a frame structure composed of two cross bars and two longitudinal bars. The two longitudinal bars are respectively arranged on both sides of the mounting frame. The two cross bars are respectively connected to the two ends of the two longitudinal bars. The lifting universal shaft is arranged in parallel between the two cross bars. The vehicle frame assembly has a simple structure, light weight, and small occupied volume.

[0011] As a preferred solution, the telescopic mechanism includes a car-receiving cylinder and a car-receiving support block. The car-receiving support block is arranged on the vehicle frame assembly. The front end of the car-receiving support block is close to the center of the vehicle frame assembly. The car-receiving cylinder is connected to the end of the car-receiving support block. The telescopic mechanism retracts after the vehicle body is successfully transferred and hung on the plate chain, preventing interference with the further transportation of the vehicle body and the plate chain. At the same time, the telescopic mechanism can reduce the occupied volume of the entire device.

[0012] Preferably, the car-receiving support block includes a fixed part and a rotating part. The two ends of the car-receiving cylinder are respectively connected to the fixed part and the rotating part. The front end of the car-receiving support block can be rotated and retracted, which can further prevent interference with the further transportation of the vehicle body and the plate chain.

[0013] As a preferred solution, a plate chain for transferring workpieces is arranged between the lifting mechanism and the telescopic mechanism. A plate chain encoder is installed on the driving shaft of the plate chain. A follower encoder synchronized with the plate chain encoder is installed on the driving shaft of the follower motor. Encoders are installed on the driving shaft of the plate chain and the driving shaft of the follower motor. The position value is fed back by the encoder, and the speed of the follower motor is adjusted in real time to ensure that the plate chain and the follower device can always run synchronously.

[0014] The beneficial effects of the present utility model:

[0015] A follower transfer device provided by the present utility model includes a follower mechanism, a lifting mechanism, and a telescopic mechanism. The three mechanisms cooperate with each other, can meet the working conditions of a high-tempo production line, improve production efficiency, reduce the difficulty of equipment operation and maintenance, reduce the equipment failure rate, and reduce the enterprise cost. The follower transfer device is practical, easy to understand, and reliable in use, and can be used for the on-line of carriers in assembly lines such as vehicle bodies, interior parts, chassis, and vehicle doors.

[0016] In addition, an encoder is installed on the plate chain drive shaft and the attendant motor drive shaft of the attendant transfer and hanging device. By using the encoder to feedback the position value, the speed of the attendant motor is adjusted in real time. After the real-time monitoring by the encoder, when the attendant transfer and hanging device is debugged in the automobile final assembly plant, the impact on the process carrier when catching up with the carrier to go online is reduced, and the smoothness of the equipment operation and the production efficiency are improved.

[0017] Therefore, the utility model can solve the technical problems of the existing attendant transfer and hanging device, such as being unable to adapt to the working conditions of high-beat production lines, having a high failure rate, and low production efficiency.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] The present utility model provides a follow - along transfer - hanging device, which includes an installation track 1, an installation frame 4, a follow - along mechanism, a lifting mechanism, and a telescopic mechanism. The follow - along mechanism is located above the installation track 1 and is slidably connected to the installation track 1. The installation frame 4 is connected to the follow - along mechanism. The lifting mechanism is arranged above the installation frame 4, and the telescopic mechanism is arranged above the lifting mechanism.

[0031] Taking the vehicle body as an example below, the technical solution of the present utility model will be further described in conjunction with the drawings.

[0032] As Figure 1 shown, a follow - along transfer - hanging device related to the present utility model includes two parallel - arranged installation tracks 1, an installation frame 4 arranged on the two installation tracks 1, a follow - along mechanism, a lifting mechanism, and two telescopic mechanisms respectively arranged on the installation frame 4.

[0033] There are four follow - along mechanisms, which are symmetrically arranged on both sides of the installation frame; each follow - along mechanism includes a traveling vehicle body assembly 2 and a follow - along motor 5. The traveling vehicle body assembly 2 is connected to the installation frame 4, and the follow - along motor 5 is arranged inside the traveling vehicle body assembly 2. The traveling vehicle body assembly 2 is a hollow box - like structure, and the follow - along motor 5 is arranged in the box - like cavity.

[0034] The lifting mechanism includes a lifting motor 6, a lifting universal shaft 12, and a vehicle frame assembly 3. The lifting motor 6 is arranged on the mounting frame 4. The drive shaft of the lifting motor 6 is connected to the end of the lifting universal shaft 12. The vehicle frame assembly 3 is connected to the side of the lifting universal shaft 12. The vehicle frame assembly 3 is a frame structure composed of two cross bars 31 and two longitudinal bars 32. The two longitudinal bars 32 are respectively arranged on both sides of the mounting frame 4. The two cross bars 31 are respectively connected to the two ends of the two longitudinal bars 32. The lifting universal shaft 12 is arranged in parallel between the two cross bars 31.

[0035] A universal shaft usually consists of two universal joints and an intermediate connecting shaft. This structure enables the universal shaft to adapt to a certain angular deviation and rotation while transmitting power. The lifting universal shaft adds vertical mobility on this basis, enabling it to achieve a certain lifting adjustment in the vertical direction to meet the requirements under specific working conditions.

[0036] There are two telescoping mechanisms, symmetrically arranged above the lifting mechanism; each telescoping mechanism includes two car receiving cylinders 7 and two car receiving support blocks 10. The vehicle body is mounted on the car receiving support blocks 10. The two car receiving cylinders 7 are respectively a right car receiving cylinder 9 and a left car receiving cylinder 15, symmetrically arranged on the vehicle frame assembly 3. The car receiving support blocks 10 are arranged on the vehicle frame assembly 3. The front end of the car receiving support block 10 is close to the center of the vehicle frame assembly 3. The car receiving cylinder 7 is connected to the end of the car receiving support block 10. The car receiving support block 10 includes a fixing part 101 and a rotating part 102. The two ends of the car receiving cylinder 7 are respectively connected to the fixing part 101 and the rotating part 102. The fixing part 101 is a thin flat block, and the rotating part 102 is a triangular step structure. The front car receiving swing arm can rotate around the rear end to reduce the occupied space.

[0037] As Figure 2 、 3 As shown in the figure, a plate chain 300 for transferring workpieces is provided between the lifting mechanism and the telescoping mechanism. A plate chain encoder is installed on the plate chain drive shaft 301, and a follower encoder synchronized with the plate chain encoder is installed on the drive shaft 51 of the follower motor.

[0038] An absolute encoder is installed on the plate chain drive shaft, and an absolute encoder is installed on the drive shaft of the follower motor. The plate chain station spacing is 6 meters. Every 6 meters, the plate chain encoder is cleared and starts counting to ensure that the plate chain and the follower device can always run synchronously. The follower motor rotates forward to chase. The value of the plate chain encoder minus the value of the follower encoder gives the distance difference; according to the distance difference, the speed of the follower motor is adjusted in real time to ensure the synchronization of the plate chain motor and the follower motor, so as to ensure that the follower transfer device transfers the vehicle body to the correct position on the plate chain. The lifting mechanism can make a horizontal movement on the translation trolley, and the translation trolley moves synchronously with the chain plate conveyor line through the positioning device.

[0039] Position calibration encoders can be used to calibrate the initial positions of large-scale machinery or industrial equipment, ensuring that the equipment can start and operate accurately according to the preset positions. The absolute encoder, which is a type of position calibration encoder, has a definite digital code corresponding to each position. Therefore, its display value is only related to the starting and ending positions of the measurement and has nothing to do with the intermediate process of the measurement.

[0040] The working process of this traveling transfer and hanging device:

[0041] Before receiving the vehicle, the left vehicle receiving cylinder 15 and the right vehicle receiving cylinder 9 extend simultaneously; the lifting motor 6 rotates forward, and through the lifting universal shaft 12, the frame assemblies 3 on both the left and right sides rise simultaneously; the vehicle receiving support block 10 holds the bottom skirt of the vehicle body 200; the lifting motor 6 rotates in reverse, and through the lifting universal shaft 12, the frame assemblies 3 on both the left and right sides descend simultaneously; after the plate chain 300 is in place, the traveling motor 5 rotates forward, and the traveling transfer and hanging device 100 runs to the in-place position along the length direction of the plate chain 300, and then the lifting motor 6 descends to the in-place position; the left vehicle receiving cylinder 15 and the right vehicle receiving cylinder 9 retract simultaneously; the vehicle body 200 is transferred and hung onto the plate chain 300, and the traveling transfer and hanging device 100 returns to its original position.

[0042] The utility model solves the drawbacks of intermittent operation in the prior art, improves the conveying efficiency of workpieces, realizes continuous conveying of workpieces by the chain plate without affecting the workpiece transfer and hanging action, overcomes the deficiencies of single actions of previous single-machine equipment, achieves the intelligence of the equipment, improves the automation and intelligence levels of the equipment, saves time costs, improves production efficiency, and has high versatility.

[0043] After the traveling transfer and hanging device is debugged in the automobile general assembly plant, encoders are installed on the plate chain drive shaft and the traveling motor drive shaft. By using the encoders to feedback position values, the speed of the traveling motor is adjusted in real time to meet the working conditions of high-beat production lines, improve production efficiency; reduce the difficulty of equipment operation and maintenance, reduce equipment failure rates, and lower enterprise costs. This traveling transfer and hanging device is practical, easy to understand, and reliable in use, and can be used for the carriers on the assembly lines of vehicle bodies, interior parts, chassis, car doors, etc. After real-time monitoring with encoders, the impact on the process carriers when catching up with the carriers to go online is reduced, and the smoothness of equipment operation and production efficiency are improved.

[0044] The above-described embodiments only represent several implementation manners of the utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
