Description

Technical Field

[0001] The present application relates to the technical field of automobile parts manufacturing, and in particular to an intelligent proofreading and feeding device for automobile parts. Background Art

[0002] The automobile parts production line is a vital component of the automobile manufacturing industry, which involves the entire production process from raw material processing to parts assembly. The automobile parts production line usually includes raw material processing, parts manufacturing, assembly and testing, automation and robotics, logistics and warehousing, and information and intelligence. The efficient operation of the automobile parts production line is crucial to automobile manufacturers, directly affecting the production cost, quality and delivery time of the automobile.

[0003] Usually, before stamping, the cut sheets of automotive parts need to be manually placed on a transport vehicle, and then sent to a processing center via an automated transport vehicle to be stamped into a specific three-dimensional shape to facilitate the subsequent assembly of automotive parts.

[0004] In the prior art, there are many types of auto parts manufactured in the process of auto parts production, and the corresponding plates are also diverse. In order to improve the work efficiency of auto parts production, the automated processing center is generally surrounded by guardrails, and workers cannot get close. They can only place the plates on the transport tools and automatically transport them to the processing center for stamping operations. This operation requires workers to always pay attention to the correspondence between the transported plates and the stamping equipment. If the workers place the wrong plates or the workers do not know that the stamping equipment has been switched, it will cause huge losses in the processing of auto parts. Utility Model Content

[0005] In order to improve the accuracy of sheet material transportation, the present application provides an intelligent proofreading and feeding device for auto parts.

[0006] The present application provides an intelligent proofreading and feeding device for auto parts, which adopts the following technical solution:

[0008] By adopting the above technical solution, before the plate is transported to the processing center for stamping, the customized pallet is first placed on the transport vehicle through the positioning edge protection limiter. At this time, the sensor block on the pallet is sensed by the corresponding proximity switch on the transport vehicle, thereby transmitting the electrical signal to the control system, and the control system drives the corresponding stamping equipment to stand by; then the plate is placed on the special pallet through the positioning of the limiter; finally, the drive member drives the transport vehicle carrying the pallet and plate matching the stamping equipment to move toward the processing center under the guidance of the guide rail for the next stamping operation. Through the cooperation of the proximity switch and the sensor block, the automatic calibration between the plate and the stamping equipment is realized, and the accuracy of the plate transportation is greatly improved, reducing the loss caused by manual operation errors.

[0013] Optionally, a conical guide surface is provided at the top end of each of the limiting rods.

[0014] By adopting the above technical solution, the setting of the tapered guide surface provides convenience for placing the plate between the multiple limiting rods.

[0017] Optionally, the driving member is a hydraulic cylinder disposed between two guide rails, a connecting seat is disposed at the bottom of the transport vehicle, and an end of a piston rod of the hydraulic cylinder is connected to the connecting seat.

[0018] By adopting the above technical solutions, the hydraulic cylinder can provide smooth movement and reduce vibration and impact during transportation; and the hydraulic cylinder has a compact structure and is easy to integrate into various transportation equipment, saving space and improving the overall design flexibility of the equipment; at the same time, the hydraulic cylinder can provide strong thrust or pulling force, which is suitable for transporting heavy equipment and goods, ensuring the stability and safety of the transportation process. Therefore, using hydraulic cylinders as the driving parts for the movement of transport vehicles greatly improves the transportation efficiency and transportation safety of transport vehicles.

[0019] Optionally, a protective cover is provided on the side of the cylinder body of the transport vehicle facing the hydraulic cylinder, and the protective cover is used to prevent pallets and plates from falling off the transport vehicle and damaging the hydraulic cylinder.

[0020] By adopting the above technical solution, when a plate or pallet accidentally falls off the transport vehicle during handling and placement, the protective cover covers most of the hydraulic cylinder, and the plate or pallet can only collide with the protective cover, thereby reducing the possibility of the hydraulic cylinder being damaged by being smashed and improving the stability of the transport vehicle moving on the guide rail.

[0021] Optionally, a plurality of lifting ears for easy lifting are arranged on the top wall of the tray.

[0022] By adopting the above technical solution, the provision of the lifting lugs facilitates the lifting equipment to carry the pallet.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Before the plate is transported to the processing center for stamping, the customized pallet is first placed on the transport vehicle through the positioning edge protection limiter.

[0042] Reference Figure 1 When the external lifting equipment lifts the pallet 4 onto the transport vehicle 2 through the lifting ear 42, the sensing block 62 on the pallet 4 is sensed by the corresponding proximity switch 61 on the transport vehicle 2, thereby transmitting an electrical signal to the control system, and the control system drives the corresponding stamping equipment to stand by.

[0043] The implementation principle of the intelligent proofreading and feeding device for auto parts in the embodiment of the present application is as follows: before the plate 01 is transported to the processing center for stamping, the pallet 4 is first hoisted onto the transport vehicle 2 by the external hoisting equipment through the hoisting lug 42. At this time, the induction block 62 on the pallet 4 is sensed by the corresponding proximity switch 61 on the transport vehicle 2, thereby transmitting an electrical signal to the control system, and the control system drives the corresponding stamping equipment to stand by;
