Description

Technical Field

[0001] This utility model relates to the field of welding automation, specifically to an automatic loading and unloading device for welding guide plates. Background Technology

[0002] Chain guides, also known as chain plates or saw plates, are the core component of a chainsaw's drive system. Their main function is to support and guide the saw chain to complete the cutting operation. They are mostly made of 50 manganese steel or 65 manganese steel, and are structurally divided into two types: modular and integral. Modular chainsaws are formed by welding or riveting multiple steel plates, and can be further divided into stacked types and replaceable heads. Integral chains are machined from a single piece of steel plate and welded with a wear-resistant alloy head, resulting in greater durability.

[0003] This application primarily addresses modular saw chain guides. Since modular saw chain guides require three pre-cut steel sheets to be assembled into the desired shape and then welded together for complete fabrication, assembly is necessary before loading the guides onto an automatic welding machine or automated spot welding machine if the welding mechanism lacks a foot position. To avoid manual loading, an automatic loading and unloading device for saw chain guides needs to be designed, while also being compatible with the assembly process. Summary of the Invention

[0004] This invention addresses the issue that some processes in existing automatic welding machines still require manual material loading and assembly. To increase the automation level of the production line, an automatic guide plate welding loading and unloading device is designed. This invention proposes an automatic guide plate welding loading and unloading device that uses electromagnets to load and unload welded saw chain guide plates from the automatic welding station. Through a multi-row structure, the device continuously or indirectly loads the automatic welding station, thus replacing the traditional method of manually assembling and loading steel plates, and increasing the automation level of the automatic welding station.

[0005] An automatic loading and unloading device for guide plate welding, mounted on the end of a robotic arm, includes: The base plate has 5 rows of lifting devices arranged in parallel on it, with equal spacing between the 5 rows. The first column uses electromagnets, and includes at least two electromagnet terminals in the same column, which are engaged with the base plate. The second to fourth columns use suction cup devices, with at least two suction cup devices in each column. The suction cup devices in the same column are controlled in series and cooperate with the base plate. The fifth column uses a gripper device, which includes at least a gripper cylinder in the same column. A sleeve is fitted on the gripping end of the gripper cylinder, and the vertical plane of the sleeve is on the same plane as the vertical plane of the fifth column.

[0006] The operating procedure of this utility model is as follows: First, the base plate is moved onto the provided material plate stack and pressed down. A portion of the saw chain guide plate material is extracted using the two to four rows of suction cups. If a temporary storage assembly is not used, the two to four rows of material are placed sequentially on the welding points of the welding device. The plate is moved out of the welding area and waits for welding to complete. The material plate, attracted by the electromagnet, is moved to the unloading area, where the electromagnet unloads the material. The initial loading action is then repeated. The terminals of the electromagnet and the second to fourth rows of suction cup devices form two rows on the floor; The terminals of the electromagnet and the suction cup devices in the second to fourth rows all use a buffer fit with the base plate; Buffer coordination includes: A movable hole is provided on the base plate. A slide rod is provided on the top surface of the electromagnet terminal or suction cup device. The slide rod is fitted into the movable hole. A buffer spring is fitted on the slide rod. A limit protrusion is provided on the top of the slide rod. When there are two gripper cylinders, the front vertical surface of the first gripper cylinder is flush with the front long side of the base plate, and the rear vertical surface of the second gripper cylinder is flush with the rear long side of the base plate. The jacket has a slot on the side facing the center vertical surface. The slot is a 90° V-shaped groove. Preferably, the device also includes a matching temporary storage assembly station; The temporary storage assembly platform is set separately on the ground. The temporary storage assembly platform includes: a rectangular base with two types of positioning holes on the top surface along the center line of the short side. There are several of each type of positioning hole, and they are evenly spaced within the same type. Only one positioning rod is installed in each of the two positioning holes, and the top of the positioning rod is conical. There is a step on each of the two short sides of the base.

[0007] Some welding equipment lacks sufficient space for the base plate to move internally and for placing materials, thus requiring the use of the temporary storage assembly table proposed in this device. Two to four rows of materials are released onto the temporary storage assembly table for assembly. The assembled, unwelded saw chain guide plates are not suitable for electromagnet attraction; therefore, a gripper device is needed for clamping and loading. Positioning the gripper device at the edge of the base plate further reduces the actual area required for the base plate to enter the welding equipment's workstation, thus adapting to automated welding equipment with limited processing areas. The advantages of this invention are: it rationally utilizes the state characteristics of the guide plates before and after assembly and welding, thereby optimizing the control using electromagnets or chucks. When using a temporary assembly table, it facilitates loading materials onto the automatic welding table in confined spaces. Attached Figure Description
