Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a platform mechanism for placing terminals of various types outside a line. Background Art

[0002] During the production of injection molds, some products such as mobile phones, computers and other electronic products have internal connectors. In order to improve signal transmission and communication connection performance, increase product strength, tensile strength and other capabilities, it is often necessary to implant foreign materials into the product. These foreign materials include stainless steel terminals, copper terminals, steel wires, copper columns, etc., among which stainless steel terminals and copper terminals are the most widely used. For products with implanted terminals, some products have structural and functional limitations, the product itself is small in size, there are many types, and the products contain irregular shapes of terminals. Therefore, the implantation accuracy of the terminals and the correct placement of the terminals on the carrier are very high. The existing terminal implantation method is to place the terminals directly on the robot carrier on the production line, and then use the robot to move the terminals to the injection mold. However, due to the wide variety of terminals, similar shapes, and difficulty in distinguishing them, it is difficult for manual placement on the production line to keep up with the production rhythm required by injection mold production. It is also easy to mix materials and place the terminals in the wrong position, resulting in an implantation success rate of less than 40%. At the same time, implanting the wrong terminals will also cause damage to the injection mold parts, resulting in very unstable product quality, resulting in a large number of product scraps and damage to the injection mold parts, causing serious resource loss to the company and doubling production costs. Therefore, the existing terminal implantation method makes it difficult for products to meet customer needs in terms of manufacturing process quality and production efficiency. Utility Model Content

The placement platform mechanism includes a base plate 1, on which at least one pair of support plates 2 are provided, and a mounting plate 3 is connected above the support plate 2, and an upper top positioning structure 4 is provided between the mounting plate 3 and the base plate 1, and a platform assembly 5 is connected above the upper top positioning structure 4, and a through hole 31 for matching the platform assembly 5 is provided on the mounting plate 3. Among them, the base plate 1, the support plate 2 and the mounting plate 3 are assembled into a support bracket for the installation of the upper top positioning structure 4, and the positioning and lifting of the platform assembly 5 are realized by the upper top positioning structure 4, so that the positioned terminals can be lifted up, and then taken away by the manipulator of the external handling mechanism and implanted into the injection mold. The through hole 31 is used to make room for the stage assembly 5 , so that the upper positioning structure 4 can drive the stage assembly 5 to rise and fall.

[0024] In the present application, the carrier assembly 5 includes a lower template 51, an upper template 52 and a carrier plate 53 arranged in sequence from bottom to top, the lower template 51 is provided with two first jacking holes 512 arranged symmetrically, the upper template 52 is provided with two second jacking holes 522 corresponding to the first jacking holes 512, and the carrier plate 53 is provided with a plurality of profiling bosses 54, each profiling boss 54 is provided with at least one terminal positioning pin 55.

The push rod 44 passes through the first lifting hole 512 and the second lifting hole 522 to lift the carrier plate 53.

[0028] In the present application, a rectangular positioning groove 451 is provided above the positioning plate 45, and the top rod 44 is inserted into the positioning groove 451, and at least one positioning column 46 is provided in the positioning groove 451.

[0029] In the present application, a pad block 42 is provided under the lifting cylinder 41 to ensure that the lifting cylinder 41 is installed firmly; a connecting groove 431 is provided on the lifting plate 43 and runs through the side of the lifting plate 43. The cross-section of the connecting groove 431 is a T-shaped structure, and two circular step protrusions matching the connecting groove 431 are provided on the piston rod of the lifting cylinder 41. The structural setting of the connecting groove 431 facilitates the rapid connection between the lifting plate 43 and the piston rod of the lifting cylinder 41; the two circular step protrusions on the piston rod of the lifting cylinder 41 are used for limiting, ensuring that the piston rod will not be displaced up and down after being engaged with the lifting plate 43, so that the lifting cylinder 41 can drive the lifting plate 43 to rise and fall.
