Description

Technical Field

[0001] This utility model relates to the field of conveyor control technology, and more specifically, to a car pin detection device with a spring cylinder. 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

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a car positioning pin detection device with a spring cylinder. This device is easy to install and use, and can accurately detect whether the positioning pin is inserted into the positioning hole of the car, thereby eliminating various risks such as the car slipping and ensuring the safety of the equipment.

[0005] As a first aspect of this utility model, a car pin detection device with a spring cylinder is provided, comprising a cylinder, a connecting plate, a tow rod, a signaling block, a spring, a proximity switch, a PLC controller, and a fieldbus slave station. The tow rod has a polyurethane block at its top for conforming to the car. The connecting plate is located at the upper end of the cylinder. The signaling block is located on the lower outer side of the tow rod. The spring is wound around the outer side of the tow rod, with its bottom end connected to the connecting plate and its top end connected to the polyurethane block. The proximity switch is used to detect whether the signaling block has moved into position. The proximity switch is electrically connected to the PLC controller via the fieldbus slave station.

[0006] Furthermore, the proximity switch is electrically connected to the fieldbus slave station via an industrial fieldbus, and the fieldbus slave station is electrically connected to the PLC controller via the industrial fieldbus.

[0007] Furthermore, the cylinder can drive the connecting plate to rise, thereby driving the spring and the tow rod to rise together. The proximity switch is used to detect whether the signal block has moved into position after the cylinder has risen to the correct position.

[0008] The automotive pin detection device with a spring cylinder provided by this utility model has the following advantages:

[0009] (1) Safe and reliable: The process of transferring the car onto the crane no longer requires human intervention and observation, reducing the possibility of personnel encountering danger;

[0010] (2) Easy to install and debug: Only one set with spring cylinder and several detection switches is needed, and it can be used after simple wiring;

[0011] (3) Wide range of applications: The car pin detection device with spring cylinder can be used in any situation where the bottom position of the car needs to be detected. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0017] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0018] This embodiment provides a vehicle pin detection device with a spring cylinder, such as... Figure 1-2 As shown, the car pin detection device with spring cylinder includes a cylinder 1, a connecting plate 2, a tow bar 3, a signal block 4, a spring 5, a proximity switch 6, a PLC controller 8, and a fieldbus slave station 9. The top of the tow bar 3 is provided with a polyurethane block 10 for attaching to the car 7. The polyurethane block 10 can prevent damage to the car 7 after attachment. The connecting plate 2 is located at the upper end of the cylinder 1. The signal block 4 is located on the lower outer side of the tow bar 3. The spring 5 is wound around the outer side of the tow bar 3. The bottom end of the spring 5 is connected to the connecting plate 2, and the top end of the spring 5 is connected to the polyurethane block 10. The proximity switch 6 is used to detect whether the signal block 4 has moved into place. The proximity switch 6 is electrically connected to the PLC controller 8 through the fieldbus slave station 9.

[0019] Preferably, the proximity switch 6 is electrically connected to the fieldbus slave station 9 via an industrial fieldbus, and the fieldbus slave station 9 is electrically connected to the PLC controller 8 via the industrial fieldbus.

[0020] Preferably, the cylinder 1 can drive the connecting plate 2 to rise, thereby driving the spring 5 and the towing rod 3 to rise together. The proximity switch 6 is used to detect whether the signal block 4 has moved into position after the cylinder 1 has risen to the position.

[0021] like Figure 3 As shown, cylinder 1 has 4 states:

[0022] State A: Cylinder 1 is in its original position, spring 5 and drag bar 3 are in their original state, and signal block 4 cannot be detected by proximity switch 6 at this time.

[0023] State B: Cylinder 1 has risen to its position and the grease block 10 has not touched the car 7. Spring 5 and tow bar 3 are in their highest positions. At this time, the signal block 4 cannot be detected by the proximity switch 6.

[0024] C state: Cylinder 1 rises to the position, the grease block 10 and the car 7 are in contact, the car 7 is in the pin normally, the spring 5 is compressed normally, and at this time the signal block 4 can be detected by the proximity switch 6.

[0025] State D: Cylinder 1 rises to the position, the grease block 10 and the car 7 are in contact, the car 7 is abnormally high, and the spring 5 has not reached the normal compression. At this time, the signal block 4 cannot be detected by the proximity switch 6.

[0026] It should be noted that the spring 5 allows the polyester block 10 to float freely with the car 7 after it comes into contact with the car 7; the cylinder 1 drives the connecting plate 2 to rise and fall, and the connecting plate 2 supports the spring 5, thereby causing the spring 5 and the tow rod 3 to move together. After the polyester block 10 is in contact with the car 7, it can no longer rise, and before the cylinder 1 and the connecting plate 2 have finished rising, the spring 5 will be compressed, thus preventing the tow rod 3 from lifting the car 7. The proximity switch 6 will output a signal after detecting the signal block 4. The PLC controller 8 controls the operation of each component in the device according to the signal transmitted from the station 9 via the fieldbus.

[0027] The working principle of the car pin insertion detection device with spring cylinder provided by this utility model is as follows: When the car 7 arrives at the detection position, the cylinder 1 rises, and the connecting plate 2, along with the spring 5 and the support block 3, rises together. When the polymer grease block 10 and the car 7 are in contact, the support block 3 can no longer rise, while the cylinder 1 and the connecting plate 2 will continue to rise to compress the spring 5 until the cylinder 1 rises to its position. When the cylinder 1 rises to its position, if the proximity switch 6 detects the signaling block 4, it outputs a position signal to the fieldbus slave station 9. After the PLC controller 8 receives the position signal through the fieldbus slave station 9, it confirms that the compression of the spring 5 is normal, determines that the car 7 is not tilted, and the pin insertion is normal. Then the cylinder 1 descends, and the car 7 can flow to the next station. Conversely, if the proximity switch 6 does not detect the signaling block 4, it will not output a position signal to the fieldbus slave station 9. The PLC controller 8 will not receive the position signal through the fieldbus slave station 9, determining that the car 7 is tilted and the pin insertion is abnormal. An alarm needs to be triggered and the next action stopped, waiting for personnel to handle the problem.

[0028] The automotive pin insertion detection device with spring cylinder provided by this utility model is easy to install and simple to use. It can accurately detect whether the positioning pin is inserted into the positioning hole of the car, thereby eliminating various risks such as the car slipping and ensuring the safety of the equipment.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
