In the manufacturing of the automobile assembly process, during the assembly operation of a single product car on a production line, assembly staff usually needs to assemble various parts and take various tools, and the assembly staff often needs to make a round trip on the production line for a plurality of times, so that a large labor load is generated, and the labor hour is wasted.

At present, part conveying devices capable of automatically following are mostly adopted in the prior art to cooperate with assembly staff to reduce the labor load of the assembly staff, for example, chinese patent application patent with the name of automatic part supplying following device and the authorized bulletin number of CN217198459U discloses a part following device. The trolley is provided with a support bracket, one side of the support bracket is provided with a notch for the part to slide in, the other side of the support bracket is provided with a baffle plate for preventing the part from sliding out, and the support bracket consists of two fluent strips which are symmetrically arranged. When the trolley is used, the parts slide into the fluent strip from the notch and slide to the baffle, then the trolley runs along the track, and after the parts are taken away by a person to be assembled, the trolley returns to the original point and receives new parts.

However, in practice it has been found that for certain specific workpieces, such as the cantilever arm of a vehicle, etc., which are generally cylindrical, they must be placed on corresponding seats or else roll over the fluent strip, thus causing the workpiece to easily slide off the trolley. In addition, when the specific workpiece freely rolls on the fluent strip, the optimal taking position is often rotated to the direction inconvenient to take, so that an assembler still needs to adjust the position of the lower workpiece first and then take the workpiece, and the labor steps of the assembler are increased. To overcome the above problems, a tray is generally disposed under the workpiece so that the workpiece can be placed stably. However, if a corresponding tray is arranged below the workpiece, when the follower device is used, the left tray cannot be automatically removed after the workpiece is removed, and the tray can only be manually removed, so that the tray is very inconvenient.

When the position travel switch is respectively contacted with the first, second and third positioners, the position travel switch sends corresponding signals, and at the moment, the controller can acquire the position of the trolley and control the moving direction and the moving speed of the trolley through the driver. It should be noted that, under normal circumstances, the assembly personnel can complete the assembly of the part when the trolley has not moved to the end of the track, therefore, in order to improve efficiency, a return key is provided on the controller on the trolley, when the assembly personnel presses the return key after completing the work, at this time, even if the position forming switch has not touched the third positioner yet, the trolley will return to the second position and the first position in sequence.

Further, the travel switch comprises a slow detection travel switch which is in communication connection with the controller. The slow detection travel switch is used for detecting whether the following speed of the trolley is too slow. When the running speed of the tracked object is too high, the tracked object is separated from the following travel switch, and then contacts with the slow detection travel switch arranged in front of the following travel switch, at the moment, the controller controls the driving part to enable the rotating speed of the driving wheel to be increased, the trolley is enabled to keep up with the tracked object, the following travel switch is enabled to contact with the tracked object again, and the trolley moves synchronously with the tracked object again.

Further, the travel switch further comprises a deceleration travel switch, a deceleration limiter matched with the deceleration travel switch is arranged on one side of the track, and the deceleration travel switch is in communication connection with the controller. Preferably, the speed reduction limiter is arranged between the second positioner and the third positioner and is close to one end of the second positioner. When the trolley returns to the second position from the third position, the trolley may be stopped unstably at the second position due to too high speed, so that the butt joint of the conveying part and other conveying belts is deviated. The speed reduction travel switch contacts the speed reduction limiter in the returning process of the trolley and sends a signal to the controller, and the controller reduces the wheel speed of the driving wheel, so that the problem that the speed is too high when the trolley returns to the second position is solved. The design does not influence the speed of the trolley to the target point, but can reduce the speed of the trolley when the trolley approaches the target point, and improves the stability. It should be noted that the distance between the second position and the first position is not generally long, and therefore, it is not necessary to provide the same speed reduction limiter between the first and second positions, but it is also possible to provide the same effect if necessary.
