Description

Technical Field

[0001] This utility model relates to the field of pin assembly technology, specifically a composite pin assembly guide mechanism. Background Technology

[0002] In the current mobile phone manufacturing industry, the mid-frame, as a key structure supporting the core components of the phone, has a direct impact on product quality and production capacity due to the efficiency and precision of its manufacturing process. However, in the current mobile phone mid-frame production process, the assembly of the side button pins still heavily relies on manual operation, requiring workers to precisely install the side button pins onto the phone's mid-frame.

[0003] A search revealed that patent application number 202121867308.8 discloses a jig for assembling side key pins of a mobile phone frame. The jig includes a base plate, a jig plate mounted on the upper end of the base plate, and a product cavity arranged in a convex shape on the upper end of the jig plate. At least one product positioning pin and at least one anti-reverse pin are mounted on the upper end of the product cavity. A side key insert is mounted on the side end of the product cavity and is fixedly mounted on the upper end of a push block. The push block is connected to a horizontally arranged push block cylinder, which is mounted on the upper end of the base plate via a pad. A side key pin suction head is mounted on the side end of the product cavity in a vertical arrangement.

[0004] Although this mobile phone frame side button assembly fixture uses a push-block cylinder to drive the side button insert to assemble the side button into the upper part of the mobile phone frame, reducing manual labor, precise alignment is a crucial step in ensuring product quality during the assembly process. However, the dimensions of both the mounting slot on the mobile phone frame and the side button are extremely precise, with very small tolerances for fit. In actual operation, when manually fixing the side button to the suction head, it is difficult to align the side button with the mounting slot on the mobile phone frame, requiring multiple adjustments to the side button's position, thus reducing assembly efficiency.

[0005] Therefore, we propose a composite pin assembly guide mechanism. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a composite pin assembly guide mechanism, which solves the problem that existing devices have difficulty aligning the side key pins with the mounting slots of the mobile phone frame, resulting in low assembly efficiency.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a composite pin assembly guide mechanism, including a base plate, a limiting plate fixedly installed in the middle of the top surface of the base plate, a groove for inserting a mobile phone frame in the middle of the top surface of the limiting plate, and an assembly guide component corresponding to the position of the mounting groove on the mobile phone frame is provided above the limiting plate.

[0008] The assembly guide component includes a hydraulic rod, a movable plate is fixedly installed at the output end of the hydraulic rod, a side key push plate is fixedly installed at the middle of the bottom surface of the movable plate, a guide plate is provided below the side key push plate and mounted on the movable plate by an elastic element, a guide groove is provided through the middle of the top surface of the guide plate, and an installation port communicating with the guide groove is opened on the front side wall of the guide plate, and the specifications of the side key push plate match the specifications of the guide groove.

[0009] The mounting port has the same specifications as the side key pin, and the length and width of the guide groove are the same as the length and thickness of the side key pin, respectively.

[0010] Preferably, the bottom surfaces of the side button push plate and the guide plate, as well as the inner wall of the groove, are all bonded with cushioning pads. The cushioning pads are made of urethane adhesive. The cushioning pads can prevent the bottom surfaces of the guide plate and the side button push plate from scratching the mobile phone frame.

[0011] Preferably, the assembly guide assembly further includes an L-shaped plate fixedly installed on the rear side of the top surface of the base plate, the hydraulic rod fixedly installed on the top surface of the L-shaped plate, the output end of the hydraulic rod penetrating through the top surface of the L-shaped plate and fixedly installed with a movable plate, wherein the hydraulic rod can be supported by the L-shaped plate.

[0012] Preferably, a limiting groove is provided on the side wall of the L-shaped plate, and a limiting rod that is slidably fitted inside the limiting groove is fixedly installed on the side wall of the movable plate. The limiting rod and the limiting groove can limit the movement of the movable plate and its bottom components, so as to improve the stability of the movable plate and its bottom components when moving, and to align the bottom end of the guide plate with the mounting groove on the mobile phone frame.

[0013] Preferably, the elastic element includes a telescopic rod and a spring. The telescopic rod is fixedly installed on both the left and right sides of the bottom surface of the movable plate. The bottom end of the telescopic rod is fixedly installed on the top surface of the guide plate. The outer surface of the telescopic rod is fitted with a spring. The upper and lower ends of the spring are respectively fixedly installed on the bottom surface of the movable plate and the top surface of the guide plate. With the telescopic rod and spring, when the bottom surface of the guide plate contacts the middle frame of the mobile phone, the hydraulic rod continuously pushes the movable plate, which can compress the elastic element, and then the side key push plate is inserted into the interior of the guide groove.

[0014] This utility model provides a composite pin assembly guide mechanism. It has the following beneficial effects:

[0015] This composite pin assembly guide mechanism uses a hydraulic rod to push a guide plate to align with the mounting slot of the phone's mid-frame. The side key pin is then inserted into the guide slot through the mounting port. The hydraulic rod continuously pushes the moving plate and the side key push plate, compressing the elastic element. The bottom end of the side key push plate then extends into the guide slot and pushes the side key pin, thus installing it into the mounting slot of the phone's mid-frame. This facilitates alignment of the side key pin with the mounting slot on the phone's mid-frame, improving assembly efficiency and solving the problem of low assembly efficiency caused by the difficulty in aligning the side key pin with the mounting slot of the phone's mid-frame in existing devices.

[0026] Furthermore, the bottom surfaces of the side key push plate 36 and guide plate 39, as well as the inner wall of the groove 21, are all bonded with buffer pads, which are made of urethane adhesive.

[0027] The buffer pads prevent the bottom surfaces of the guide plate 39 and the side button push plate 36 from scratching the phone's frame.

[0028] Furthermore, the assembly guide assembly 3 also includes an L-shaped plate 31 fixedly installed on the rear side of the top surface of the base plate 1, a hydraulic rod 33 fixedly installed on the top surface of the L-shaped plate 31, and the output end of the hydraulic rod 33 passes through the top surface of the L-shaped plate 31 and is fixedly installed with a movable plate 34.

[0029] The hydraulic rod 33 can be supported by the L-shaped plate 31.

[0030] Furthermore, a limiting groove 32 is provided on the side wall of the L-shaped plate 31, and a limiting rod 35 that is slidably fitted inside the limiting groove 32 is fixedly installed on the side wall of the movable plate 34.

[0031] The limiting rod 35 and the limiting groove 32 can limit the movement of the moving plate 34 and its bottom components, thereby improving the stability of the moving plate 34 and its bottom components during movement, and facilitating the alignment of the bottom end of the guide plate 39 with the mounting groove on the mobile phone frame.
