Description

Technical Field

[0001] The utility model belongs to the technical field of automobile assembly, and particularly relates to a rhythm self-adaptive system for an automobile assembly production line. Background Art

The existing automobile final assembly production line is a rigid assembly line layout, which is suitable for the production of a small number of models and large batches. However, with the continuous development of the automobile industry and the continuous updating of customer needs, the final assembly production line needs to meet the production mode of customization, multiple models and small batches. The existing final assembly production line has the following defects:

[0003] (1) Lack of flexibility: the final assembly line has a rigid layout, and the amount of modification work required when introducing new models is large;

[0004] (2) Cycle time waste: Since the number of workstations is fixed, when producing multiple models, the positions can only be arranged according to the maximum demand, resulting in long-term overall cycle time waste on the production line;

[0005] (3) The rhythm cannot be adjusted. Because the production line is arranged in series, the rhythm of the production line cannot be quickly adjusted according to market demand, resulting in waste of manpower or insufficient production;

[0006] (4) Operating efficiency is limited. For a production line with a rigid series arrangement, as long as one workstation fails, the entire line needs to be stopped and wait for repair, which affects the production line efficiency.

[0007] Therefore, an adaptive system for the beat of automobile assembly production line is needed. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example, reference Figure 1 to Figure 2 .

[0030] It includes a moving module, a scheduling module, an assembly module and an identification module;

[0031] The identification module is installed on the mobile module, and is used to detect the model of the vehicle body on the mobile module and send the detection signal to the scheduling module. At the same time, the identification module sends the arrival signal of the mobile module to the assembly module;

[0032] The scheduling module is used to adjust the moving path of the moving module according to the detection signal sent by the identification module, and send the adjustment signal to the moving module;

[0033] The mobile module includes an AVG slide plate 1, which is used to carry and transfer the vehicle body that needs to be assembled, and the mobile module drives the vehicle body forward according to the route selected by the adjustment signal;

[0034] The assembly module is arranged at the assembly station of the final assembly production line, and is used for assembling the vehicle body after receiving the arrival signal sent by the identification module when the vehicle body transported by the AVG slide plate 1 arrives at the assembly module.

[0035] The staff will place and fix the car body that needs to be assembled on the AVG skateboard 1 through the equipment. The identification module installed on the AVG skateboard 1 can identify the model of the car body. The scheduling module plans the path and destination of the AVG skateboard 1 according to the model information identified by the identification module. The scheduling module includes a computer, a signal transmitter and a signal receiver. The signal receiver is used to receive the detection signal sent by the identification module, identify and process the detection signal through the computer, give the moving route of the mobile module through the scheduling program pre-installed in the computer, and then send the adjustment signal to the mobile module through the signal transmitter. A signal receiver is synchronously installed on the AVG skateboard 1. When the scheduling module finds that the assembly rhythm of the car body is inconsistent with the assembly rhythm of most of the car bodies as a whole, the AVG skateboard 1 can be controlled to move to the branch assembly path by adjusting the signal. The assembly module is generally an assembly island on each workstation, including various robotic arms and electric guns. When a certain workstation fails and causes a blockage in a general assembly line, the scheduling module can schedule the AVG slide plate 1 to avoid the faulty workstation and move it to other parallel workstations according to the blockage situation. Compared with the existing automobile general assembly line that uses a rigid conveyor chain to transport the car body, this application can be more flexible and will not completely affect the overall general assembly line due to a certain node failure.

[0036] When the AVG slide 1 transports the vehicle body to the workstation, the identification module will confirm the model of the vehicle body on the AVG slide 1 and provide the assembly module with the information of the arrival of the AVG slide 1. The identification module includes a camera and an RFID reader. The camera is used to obtain the vehicle body model code. The RFID reader can cooperate with the RFID transmitter on the assembly module, so that the identification module generates the arrival information and sends the arrival information to the assembly module. After the identification module sends the arrival information of the AVG slide 1 to the assembly module, the assembly module will start the robot to drive the electric gun to install the parts on the vehicle body. Some parts may also be assembled manually.

[0037] The AVG skateboard 1 includes a frame 2, wheels 3, a control panel, a battery, an indicator light 5, an emergency stop unit and a radar 6. The frame 2 is provided with a control cabin 7 and a power cabin 4. The control panel is installed in the control cabin 7, the battery is installed in the power cabin 4, the wheel 3 is rotatably installed on the frame 2, and emergency stops are installed at both ends of the frame 2. The radar 6 is installed at any corner of both ends of the frame 2. The AGV skateboard has double steering wheels, which can turn on the spot and move sideways, so any path can be adjusted according to the scheduling module. The control panel on the AVG skateboard 1 is used to receive and convert signals from the intelligent scheduling system. The emergency stop unit is used to control the brakes of the AVG skateboard 1 to avoid collisions of the AVG skateboard 1, and at the same time, the AVG skateboard 1 can be docked at an accurate position. The radar 6 allows the AVG skateboard 1 to achieve self-adjustment on the way to avoid collisions.

[0038] A safety touch edge 8 is installed at one end of the frame 2 in the forward direction. The safety touch edge 8 is electrically connected to the emergency stop part. When the safety touch edge 8 is triggered, the emergency stop part will emergency brake the AVG slide 1, which can protect both the AVG slide 1 and the impacted object in an emergency.

[0039] Indicator lights 5 are installed at the corners of the two ends of the frame 2 away from the radar 6 to remind the staff.

[0040] The emergency stop unit includes a left front emergency stop 9, a right front emergency stop 10, a left rear emergency stop 11 and a right rear emergency stop 12. The emergency stop unit is connected to the wheels 3. Each emergency stop unit is used to control a wheel 3, which can provide a strong braking effect for the AVG skateboard 1.

These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
