Description
TECHNICAL FIELD
[0001] The present application relates to the field of automation production, in particular to a jig transverse transfer line changing device for automatic feeding and material assembly processing of an automatic production line and a jig line changing process thereof. BACKGROUND
[0002] Automation refers to the replacement of manual work by machines to complete various production and processing. In the field of automation equipment, since the production products are generally composed of multiple scattered parts, various parts need to be automatically assembled by equipment during actual production to form a complete product structure. Therefore, automatic assembly processing of various materials is widely used in many fields, such as various intelligent terminal devices, mobile phones, tablet computers, smart watches, batteries, power supplies, and various daily products and toys, all of which have production needs of material automation assembly. Since the types and specifications of materials in the automatic assembly process are different, existing automatic assembly technologies generally use separate assembly equipment for different materials, making it difficult to form standardized and universal assembly equipment.
[0003] For the automatic assembly of materials, different materials need to be assembled, so the assembled materials such as various electronic components and substrate materials such as PCB boards are involved. Therefore, the automatic assembly process of materials as a whole includes three process sections, namely, automatic feeding process of assembled materials, feeding process of substrate materials, and automatic assembly process of assembled materials and substrate materials.
[0004] The feeding process of substrate materials generally uses a jig as a device carrier. After the jig clamps the substrate material, the substrate material is transported to the assembly station, and the assembled material is taken out by the assembly robot and automatically assembled on the substrate material. After the jig clamps the substrate material, it is generally directly transported to the assembly station of the production line by a transportation mechanism, and the assembly robot assembles the material on the substrate material. After assembly is completed, the jig moves the substrate material to the next station until the material assembly is completed. In actual assembly process, when multiple assembly lines are required due to different assembly processes or when the entire assembly line needs to be divided into multiple unit assembly lines due to site factors, the jig needs to be automatically transferred between each unit assembly line. However, during the transfer of the jig between different assembly lines, problems such as jig access and push-out, jig positioning, and jig transmission failure are involved.
[0005] In addition, for the jig of single-rail transmission, the jig is freely embedded on the slide rail, and the jig is pressed on the transmission belt arranged on one side of the slide rail through the gravity of the jig, and the jig is driven to move forward through the static friction force between the jig and the transmission belt. For this kind of transmission mode, after the jig is positioned, since there are many workstations arranged on the whole production line, the transmission belt needs to keep transmitting forward continuously, and during the assembly process of a single workstation, the jig needs to be positioned while being separated from the transmission belt to avoid continuous friction between the transmission belt in motion and the bottom of the positioned jig. Therefore, a jig positioning mechanism needs to be designed to meet the above process requirements. SUMMARY

The first line segment, the discharge line segment and the second line segment take a single straight slide rail as a movement limiting structure, take a jig as a material bearing structure, and take a transmission belt arranged on the side of the straight slide rail as a driving execution structure. After the jig is pressed against the transmission belt by its own gravity, the transmission belt drives the jig to move along the single slide rail in a straight line. The first line segment, the second line segment and the discharge line segment of the present application are provided with a jig positioning mechanism as an execution device for blocking and positioning the jig.

The two ends of the limiting swing block are respectively rotatably connected in the side grooves. The limiting swing block ensures that the jig base and the jig carrier are connected together. The connection realizes the adjustable state of the distance between the jig base and the jig carrier and the relative position of the jig base and the jig carrier in the horizontal direction. The connecting spring cooperates to form an elastic support. One side of the jig base is connected with a sliding seat, which is embedded on a conveying slide rail. The bottom of the jig base is provided with a contact layer to contact the conveying belt on one side of the conveying slide rail. In addition, the side of the jig base is also provided with a first roller and a second roller rotatably connected to the side wall of the jig base.

When the jig moves to the jig positioning mechanism, the blocking block blocks the jig carrier on the upper layer of the jig, the jig carrier stops moving, and the bottom base on the lower layer of the jig continues to move forward due to inertia, at this time, the first roller slides upwardly along the first inclined surface, the first inclined top block presses downwardly the positioning spring, until the first roller falls into the positioning groove when the first roller slides to the top of the first inclined surface, at this time, the first inclined top block loses the downward pressure of the first roller, the rebound force of the positioning spring pushes the second inclined top block upwardly, the second inclined surface on the top of the second inclined top block abuts against the second roller of the jig, and the second roller is lifted upwardly, the second roller drives the bottom base to move upwardly against the internal stress of the connecting spring, so as to realize the separation of the bottom of the bottom base from the conveying belt, and at the same time, the spacing between the bottom base and the jig carrier is shortened through the flexible connection of the limiting swing block. Through the above-mentioned structural design, the lifting of the jig is completed at the same time when the movement of the jig is blocked through one power output, so as to make the transmission between the jig and the conveying belt invalid, and to facilitate the assembly and processing.
[0028] The present application is directed to the process requirement of the horizontal moving mechanism of the jig in the transfer between different automatic assembly lines, the horizontal moving mechanism of the present application takes the horizontal moving base horizontally arranged between the first line body and the second line body as the bearing structure, two horizontal moving slide rails are arranged in parallel and spaced apart on the horizontal moving base, the horizontal moving slide rails are slidably connected with the horizontal moving support plates, the horizontal moving single slide rails are arranged on the top of the horizontal moving support plates, the conveying belts are arranged on one side of the horizontal moving single slide rails, the horizontal moving support plates are connected with the lead screws arranged between the two horizontal moving slide rails through the screw rod bases, the horizontal moving motor arranged at one end of the horizontal moving base drives the lead screws to rotate back and forth so as to drive the horizontal moving support plates to move back and forth between the first line body and the second line body.

A jig positioning mechanism is arranged on one side of the horizontal moving support plate. When the horizontal moving support plate moves to one side of the first line body, the horizontal moving single slide rail is butt jointed with the single slide rail of the first line body, the jig is slid into the horizontal moving single slide rail from the first line body, and is positioned by the jig positioning mechanism, the horizontal moving support plate drives the jig to move to one side of the second line body, and the jig is driven to slide into the single slide rail of the second line body through the movement of the conveyor belt on the side of the horizontal moving single slide rail, so that the automatic jig receiving, jig positioning, horizontal moving of the jig, and jig transfer are realized.
