Description

Technical Field

[0001] This utility model relates to the field of automation technology, specifically to an automatic assembly fixture for mobile phone SIM card trays. Background Technology

[0002] A SIM card tray is a component in a mobile phone used to hold the SIM card and memory card. It plays a crucial role in modern smartphones. For example, the tray securely holds the SIM card, ensuring it stays in place and doesn't loosen or shift. Some trays also have memory card slots, allowing users to expand the phone's storage capacity by inserting a microSD card. Some high-end phones feature waterproof and dustproof trays, using a sealed design to prevent moisture and dust from entering the phone, thus improving its durability.

[0003] As mobile phones have become an essential part of people's lives, the efficiency of mobile phone production can be further improved. However, in the process of SIM card assembly in mobile phone manufacturing, manual assembly is still required, and the labor cost and efficiency are far from keeping up with the production demand. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic assembly fixture for mobile phone SIM card trays, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic assembly fixture for mobile phone SIM card trays, comprising a placement plate, a driving cylinder on the top of the placement plate, a connecting block on the driving end of the driving cylinder, a pushing block on one side of the connecting block, a positioning post and a SIM card tray base on the surface of the placement plate, a SIM card tray placement groove on the top of the SIM card tray base, and a movable limiting block elastically connected to the inner side of the SIM card tray placement groove by a spring pin.

[0006] Optionally, a limit block is provided on one side of the drive cylinder, and a limit bolt passes through one side of the connecting block.

[0007] Optionally, the size of the push block is adapted to the size of the card holder placement slot, and the shape of the movable limiting block is trapezoidal.

[0008] Optionally, the surface of the placement plate may also be provided with grooves for easy picking and placing by the grippers.

[0009] Optionally, a slider is provided at the bottom of the connecting block, and the slider is slidably connected to the slide rail.

[0010] Optionally, the slide rail is disposed on the placement plate, located below the connecting block.

[0011] This utility model provides an automatic assembly fixture for mobile phone SIM card trays, which has the following beneficial effects:

[0012] This automatic SIM card tray assembly fixture uses a drive cylinder to drive a connecting block, which in turn drives a pusher block to push the SIM card tray onto the base, inserting it into the SIM card tray mounting hole. This achieves automatic SIM card tray assembly, greatly improving assembly efficiency and effectively avoiding high labor costs. The fixture incorporates limit blocks and bolts, allowing for adjustable push distances to accommodate different SIM card tray sizes, significantly enhancing its flexibility and adaptability. The trapezoidal design of the movable limit blocks accommodates SIM card trays with smaller inner sections and larger outer sections, while the slider and slide rail design improves the stability of the pusher block when pushing the SIM card tray.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: an automatic assembly fixture for mobile phone SIM card trays, including a placement plate 1. The surface of the placement plate 1 is provided with a groove 11 for convenient gripping of the mobile phone frame. A driving cylinder 2 is provided at the top of the placement plate 1. A connecting block 3 is provided at the driving end of the driving cylinder 2. A slider 12 is provided at the bottom of the connecting block 3. The slider 12 is slidably connected to a slide rail 13. The slide rail 13 is provided on the placement plate 1 and located below the connecting block 3. The slider 12 and the slide rail 13 are provided to improve the stability of the push block 4 when pushing the SIM card tray. A limit block 5 is provided on one side of the driving cylinder 2. A limit bolt 6 passes through one side of the connecting block 3. By adjusting the extension length of the limit bolt 6, the fixture can adjust the pushing distance according to different SIM card tray sizes, greatly improving the flexibility and adaptability of the fixture. A push block 4 is provided on one side of the connecting block 3. The size of the push block 4 is adapted to the size of the SIM card tray placement groove 8.

[0019] The surface of the placement plate 1 is provided with multiple positioning posts 14 and a card tray base 7. The positioning posts 14 are used to fix the middle frame of the mobile phone, which not only provides positioning but also prevents it from moving and affecting assembly. The top of the card tray base 7 is provided with a card tray placement groove 8. The inner side of the card tray placement groove 8 is elastically connected to a movable limiting block 10 by a spring pin 9. When the push block 4 pushes the card tray, the movable limiting block 10 can retract through the spring pin 9 to clear the assembly path. The movable limiting block 10 is trapezoidal in shape, which adapts to the shape of the card tray, which is smaller inside and larger outside, and at the same time positions the card tray.

[0020] In this invention, the working steps of the device are as follows:

[0021] Place the SIM card tray into the SIM card tray placement slot 8 at the top of the SIM card tray base 7, and place the mobile phone frame precisely into the assembly position of the placement plate 1 according to the positioning post 14 through the feeding device.

[0022] Then, the drive cylinder 2 drives the connecting block 3, which in turn carries the push block 4, to push the card tray along the slide rail and push it into the mobile phone card tray mounting hole. When the card tray moves forward, the movable limit block 10 will be pushed by the push block 4 and retract through the spring pin 9 to clear the assembly path.

[0023] Until the limiting bolt 6 on the connecting block 3 reaches the limiting block 5, blocking the pushing block 4 from moving forward, the card tray is inserted into the mobile phone, completing the automatic assembly of the card tray. The driving cylinder 2 retracts and returns to its original position, and then the mobile phone frame with the assembled card tray is removed to proceed with the assembly of the next mobile phone card tray.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
