Description
Technical Field
[0001] This utility model belongs to the field of conveyor control technology, and in particular relates to a vehicle entry detection system. Background Technology
[0002] In the automobile production process, there is a process of transferring cars onto a lifting device. The positioning pins on the lifting device are inserted into the positioning holes of the car to ensure that the car is in the correct position and will not slide. If the positioning pins are not inserted into the positioning holes of the car accurately, the car may slip off, causing huge losses.
[0003] During the process of transferring a car onto a crane, proper pin insertion checks can be used to ensure that the positioning pins are accurately inserted into the positioning holes of the car, eliminating the risk of the car slipping and avoiding unnecessary losses. Summary of the Invention

The control module is communicatively connected to the lifting mechanism, the ranging module, and the lifting module. The ranging module is installed on the top of the lifting module and faces the bottom of the car. The lifting mechanism is provided with a positioning pin. The car is loaded onto the lifting mechanism and positioned by the positioning pin.
[0006] The lifting module can drive the distance measuring module to rise and fall. The distance measuring module is used to detect the distance between itself and the vehicle and generate a detection signal. The control module can control the lifting module to rise and fall and control the operation of the lifting mechanism. The control module can compare the detection signal with a preset distance range to determine whether the vehicle is stuck in the mounting pin.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0021] In the embodiments of this utility model, Figure 1 , Figure 2 and Figure 3This is a structural diagram illustrating the specific structure of an automobile entry detection system according to this utility model, as shown below. Figure 1 , Figure 2 and Figure 3 As shown, this utility model includes:
[0022] The system includes a lifting mechanism 11, a control module 9, a ranging module 10, and a lifting module 12. The control module 9 is communicatively connected to the lifting mechanism 11, the ranging module 10, and the lifting module 12. The ranging module 10 is mounted on the top of the lifting module 12, facing the bottom of the vehicle 5. The lifting mechanism 11 is equipped with a positioning pin, and the vehicle 5 is loaded onto the lifting mechanism 11 and positioned by the positioning pin. The control module 9 is connected to an audible and visual alarm 13.
[0023] The lifting module 12 can drive the distance measuring module 10 to rise and fall. The distance measuring module 10 is used to detect the distance between itself and the vehicle 5 and generate a detection signal. The control module 9 can control the lifting module 12 to rise and fall and control the operation of the lifting mechanism 11. The control module 9 can compare the detection signal with a preset distance range to determine whether the vehicle 5 is stuck in the mounting pin.
[0024] When the detection signal is within a preset distance range, it is determined that the vehicle 5 is stuck in the mounting pin, at which point the control module 9 controls the lifting mechanism 11 to operate. Conversely, the control module 9 controls the audible and visual alarm 13 to sound an alarm.
[0025] In one embodiment of the present invention, the lifting device structure includes: a boom 6 and a boom drive device, the boom drive device being connected to the control module 9, the boom drive device being able to drive the boom 6 to move, and the positioning pin being disposed on the boom 6.
[0026] In one embodiment of this utility model, the control module 9 includes a PLC master controller 7 and a field slave controller 8. The PLC master controller 7 is connected to the field slave controller 8, and the field slave controller 8 is connected to the ranging module 10 and the lifting module 12.
[0027] In one embodiment of the present invention, the lifting module 12 includes a cylinder 1, a connecting plate 2, and a top block 3. The connecting plate 2 is installed on the top of the telescopic end of the cylinder 1. The top block 3 and the ranging module 10 are both installed on the upper surface of the connecting plate 2. When the cylinder 1 is in the extended state, the top block 3 abuts against the lifting mechanism 11. The cylinder 1 is connected to the control module 9.
[0028] In one embodiment of this utility model, the ranging module 10 includes a laser ranging sensor 4.
[0029] like Figure 1 , 2 As shown in Figures 3 and 4, this utility model includes a cylinder 1 and a connecting plate 2 for position control, a top block 3 for contacting the lifting device 6, a laser rangefinder 4 for detecting the distance from the connecting plate 2 to the top of the vehicle 5, and a PLC master controller 7 and a slave controller 8 on an industrial fieldbus for automatic control. The cylinder 1 drives the connecting plate 2 to rise and fall, and the connecting plate 2 moves up and down together with the top block 3 and the laser rangefinder 4. After the top block 3 contacts the lifting device 6, it cannot rise further; this point serves as a reference point, ensuring that the relative positions of the laser rangefinder 4 and the lifting device 6 are always consistent, and the values measured by the laser rangefinder 4 under such identical conditions are comparable. The PLC master controller 7 on the industrial fieldbus controls the operation of each device by receiving signals from the slave controller 8 on the fieldbus.
[0030] The specific electrical principles are as follows: Figure 1 , 2 As shown in Figure 3, when cylinder 1 reaches its rising position, i.e., after top block 3 abuts against the hanger 6 and top block 3 and hanger 6 are in contact, the value detected by laser rangefinder 4 will be used. The specific detection process is as follows: when vehicle 5 arrives at the detection position, cylinder 1 rises, and connecting plate 2 rises together with top block 3 and laser rangefinder 4. Top block 3 and hanger 6 are in contact, and laser rangefinder 4 detects the distance from connecting plate 2 to vehicle 5. PLC master controller 7 receives this value through fieldbus slave controller 8 and determines whether the value is within the normal range. When the value is within the normal range, it indicates that vehicle 5 is not tilted and is properly engaged. Cylinder 1 descends, the hanger starts, and vehicle 5 moves to the next workstation. Conversely, when the value is not within the normal range (D2 > D1), it indicates that vehicle 5 is tilted and the engagement is abnormal. The alarm module sounds an alarm and stops the next action, waiting for personnel to handle the problem. This application is applicable to various vehicle models, and no additional focusing rangefinder switch is needed, making it very convenient and quick.
[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
