Description

Technical Field

[0001] This utility model relates to the technical field of magnetic core assembly equipment, and in particular to a secondary positioning mechanism for terminal loading and unloading. Background Technology

[0002] A magnetic core is a magnetic metal oxide that is widely used in the field of electronic equipment. It is commonly used to manufacture magnetic core tubes, which are the core components of electromagnets and can be used as components of coils and other devices in various electronic equipment.

[0003] Terminals are key components in electronic and electrical equipment used to achieve circuit connections. They typically refer to the metal contacts in connectors, used to secure and connect wires or cables, ensuring reliable transmission of current or signals between wires or between wires and devices. In existing technology, mounting terminals on a magnetic core requires applying adhesive to the core, followed by mounting the terminals onto both sides of the core and then curing. Because the mounting precision of terminals on the magnetic core is high, the positioning accuracy when placing the terminals onto the core is crucial. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a secondary positioning mechanism for terminal loading and unloading, thereby improving the assembly accuracy of magnetic cores for terminal assembly.

[0005] The technical solution of this utility model is as follows: a terminal loading and unloading secondary positioning mechanism, comprising a terminal feeding assembly and a terminal picking assembly respectively disposed on both sides of a conveyor frame. The terminal feeding assembly includes a vibrating feeding plate, a linear vibrating guide rail connected to the vibrating feeding plate, and a positioning and unloading module connected to the outlet end of the linear vibrating guide rail. The terminal picking assembly includes a terminal picking robot and a positioning platform disposed below the terminal picking robot. The positioning platform has a plurality of positioning grooves arranged through it. The bottom of the positioning platform is provided with a guide block adapted to the positioning hole on the magnetic core. The guide block is disposed on the side of the positioning groove. The guide block has a guide slope arranged inward around its perimeter. The terminal picking robot positions the terminal on the positioning and unloading module through the positioning platform and then places it onto the magnetic core product on the fixture on the conveyor frame.

[0006] As can be seen from the above scheme, the vibrating feeding plate and the linear vibrating guide rail are used to realize the vibration feeding of terminals, the positioning and feeding module is used for the primary positioning of terminals after unloading, and the picking robot is used to transfer the terminals on the positioning and feeding module to the positioning platform for secondary positioning before assembly with the magnetic core. This utility model realizes the positioning before picking and the positioning during feeding through the positioning and feeding module and the positioning platform, respectively, thereby realizing the secondary positioning of terminals for unloading and loading, thereby improving the assembly accuracy of terminals on the magnetic core.

[0007] The positioning and feeding module includes a partition cylinder, a partition push rod connected to the output end of the partition cylinder, a linear module, and a loading seat disposed on the linear module. The partition cylinder and the loading seat are respectively disposed on both sides of the linear vibration guide rail. The side of the linear vibration guide rail near the outlet end is provided with a locking groove adapted to the partition push rod. The loading seat is provided with several loading slots adapted to the terminals, and the outer side of the loading slots is provided with an opening facing the linear vibration guide rail. Therefore, the partition cylinder is used to drive the partition push rod to push inward through the opening, causing the terminals on the linear guide rail to move forward one by one and feed into the positioning and feeding module. The loading seat is used for positioning and loading the terminals before they are picked up.

[0008] The terminal picking robot includes a picking frame, a transverse module mounted on the picking frame, a lifting module connected to the output end of the transverse module, a picking seat connected to the output end of the lifting module, and several terminal picking suction heads mounted on the picking seat. Each terminal picking suction head has several contoured suction blocks adapted to the terminals at its bottom. Positioning grooves correspond to the contoured suction blocks, and the spacing between adjacent contoured suction blocks matches the spacing between adjacent loading slots. Therefore, the transverse module and the lifting module are used to drive the picking seat to move forward and backward and up and down, respectively, and the picking suction heads are used to pick up the terminals using vacuum negative pressure.

[0009] The terminal picking suction head is fitted with an elastic element. Therefore, the elastic element is used to achieve floating feeding of the terminal picking suction head.

[0010] The positioning platform is connected to the output end of the drive cylinder, and the positioning platform is connected to the material pick-up seat via a connecting block. Therefore, the drive cylinder is used to move the positioning platform up and down below the terminal material pick-up head.

[0011] The positioning groove includes a first limiting part and clearance parts disposed at both ends of the first limiting part. The first limiting part has inclined surfaces on both sides from top to bottom, and the clearance parts are waist-shaped. Therefore, the first limiting part is used to limit the middle of the terminal, the clearance parts are used to avoid damaging the terminals at both ends during secondary positioning, and the inclined surfaces guide the terminals as they are unloaded from the positioning groove onto the magnetic core.

[0012] The end of the partition push rod is tapered. This allows it to be pushed inward from the opening on the side of the linear guide rail, causing the terminal to move forward and thus loading the material onto the loading seat. Attached Figure Description

[0023] The positioning platform 5 is connected to the output end of the drive cylinder 52. The positioning platform 5 is connected to the material picking seat 44 through the connecting block 53.

The first limiting part 511 has inclined surfaces 513 on both sides from top to bottom. The clearance part 512 is waist-shaped.

[0024] The working process of this utility model is as follows: Terminals 100 enter the linear guide rail 2 from the vibrating feeding plate 1 and are discharged sequentially. The isolation cylinder 31 drives the isolation push rod 32 to push them in from the side of the linear guide rail 2. The terminals at the end of the vibrating guide rail 2 are fed into the loading groove 341 on the loading seat 34. The linear module 33 drives the loading seat 34 to move, thereby realizing the sequential loading of terminals 100 on the loading seat 34. After the terminals are positioned and loaded in rows on the loading seat 34, the transverse module 42 and the lifting module 43 drive the terminal picking suction head 45 and the positioning table 5 to move to the top of the loading seat 34. The driving cylinder 52 drives the positioning table to move down, and the guide slope 541 on the guide block 54 moves down into the positioning hole 210 of the magnetic core, so that the positioning groove 51 is accurately aligned with the terminal installation position on the magnetic core.
