Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a multi-station fixture for processing AI conference machine motherboards. Background Technology

[0002] The manufacturing process of AI conference machine motherboards typically involves multiple steps (such as SMT placement, component soldering, and functional testing), and fixtures are required to fix the motherboard during the manufacturing process.

[0003] A search revealed a utility model patent with patent authorization announcement number CN210388942U, which discloses a POS machine motherboard processing fixture. This fixture includes a base plate, a first pressure plate, a second pressure plate, and a top plate. A first cylinder mounting plate is respectively provided on the two transverse sides of the top plate. A first cylinder and a first mounting seat are mounted on the first cylinder mounting plate. The working guide rod of the first cylinder is a first cylinder push rod, and the upper end of the first cylinder push rod is fixedly connected to the first pressure plate. The first mounting seat and the first pressure plate are movably connected via a first rotating shaft. A second cylinder mounting plate is respectively provided on the two longitudinal sides of the top plate. A second cylinder and a second mounting seat are mounted on the second cylinder mounting plate. The working guide rod of the second cylinder is a second cylinder push rod, and the upper end of the second cylinder push rod is fixedly connected to the second pressure plate. The second mounting seat and the second pressure plate are movably connected via a second rotating shaft.

[0004] Existing fixtures are mostly single-station designs. After the motherboard completes one process, it needs to be manually disassembled and re-clamped to the next station, resulting in low production efficiency and inability to meet the needs of mass production. At the same time, traditional fixtures only rely on horizontal constraints to fix the motherboard, and lack stable vertical limits. They are prone to displacement during high-speed drilling or vibration welding, and are not stable enough. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-station fixture for processing AI conference machine motherboards, which solves the problem of low processing efficiency of existing single-station fixtures, and also solves the problem of traditional fixtures lacking stable positioning in the vertical direction of the motherboard.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station fixture for processing AI conference machine motherboards, comprising a base, a motor fixedly mounted on the bottom of the base, the output shaft of the motor passing through the base and connected to the base via a bearing, a turntable fixedly connected to the end of the output shaft, two motherboard positioning mechanisms symmetrically arranged on the upper end of the turntable, and a support ring fixedly connected to the lower edge of the turntable, the support ring being rotatably connected to the base.

[0007] Preferably, the bottom of the support ring is provided with a plurality of ball bearings, which are arranged in a circular array along the circumference of the support ring, and the ball bearings are slidably connected to the upper end of the base. The arrangement of the ball bearings reduces the relative friction between the support ring and the base.

[0008] Preferably, a mounting support is fixedly connected to the bottom edge of the base, and the flange of the mounting support has bolt holes. The mounting support provides structural support for the entire structure.

[0009] Preferably, the motherboard positioning mechanism includes two fixture seats fixedly connected to the upper end of the turntable. A second motor is fixedly mounted on the outside of each fixture seat. The output shaft of the second motor passes through the fixture seat and is connected to it via a bearing. A bidirectional screw is fixedly connected to the end of the output shaft of the second motor. Two movable seats are threadedly connected to the outer side of the bidirectional screw. The movable seats pass through the fixture seats and are slidably connected to them. A sliding column is slidably connected to the top of each movable seat, and the sliding column passes through the movable seat. An L-shaped plate is fixedly connected to the top of the sliding column. By setting up two motherboard positioning mechanisms, the efficiency of motherboard processing can be improved.

[0010] Preferably, an inclined plate is fixedly connected to the upper end of the L-shaped plate, and two support rods are fixedly connected to the upper edge of the tooling base. A pressure plate is fixedly connected to the top of each support rod, and the position of the pressure plate corresponds to the position of the inclined plate. During the lateral movement of the inclined plate, it can be subjected to the reaction force of the pressure plate, thereby driving the L-shaped plate to move downward. At the same time, the bending part of the L-shaped plate is used to press and fix the main plate in the vertical direction.

[0011] Preferably, a limiting block is fixedly connected to the bottom of the sliding column, and the limiting block is slidably connected inside the movable seat. A spring is provided inside the movable seat, one end of the spring is fixedly connected to the limiting block, and the other end of the spring is fixedly connected to the inner surface of the movable seat. The spring force can act on the L-shaped plate through the limiting block and the sliding column, thus providing an auxiliary resetting function.

[0012] Preferably, a guide frame is fixedly connected to the inner bottom of the tooling base, and the guide frame passes through the movable base and is slidably connected to the movable base. The guide frame guides the lateral movement of the movable base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model sets up a turntable driven by an electric motor on the base, and sets up two motherboard positioning mechanisms on the turntable. In this way, when one station is processing motherboards, the other station can load and unload materials simultaneously. The turntable can be quickly switched after the electric motor drives it to rotate 180°, which reduces the ineffective waiting time for motherboard processing and improves efficiency.

[0015] 2. The motherboard positioning mechanism of this utility model contains a bidirectional screw driven by an electric motor, which causes the two moving seats to move towards or away from each other, thereby clamping the motherboard in the horizontal direction. Moreover, during the process of the moving seats moving towards each other, when the inclined seat slides down to the bottom of the pressure plate with the moving seats, the spring preload interacts with the inclined surface to automatically generate a vertical downward pressure, forming a constraint on the motherboard in the vertical direction, thereby strengthening the positioning of the motherboard and making it less prone to loosening.

A bidirectional screw 43 is fixedly connected to the end of the output shaft of the second motor 42. Two movable seats 44 are connected to the outside of the rod of the bidirectional screw 43 through a thread.

Two support rods 411 are fixedly connected to the upper edge of the tooling base 41. A pressure plate 412 is fixedly connected to the top of each support rod 411, and the position of the pressure plate 412 corresponds to the position of the inclined plate 47. During the lateral movement of the inclined plate 47, it can be subjected to the reaction force of the pressure plate 412, thereby driving the L-shaped plate 46 to move downward. At the same time, the bending of the L-shaped plate 46 is used to press and fix the main plate vertically.

[0024] The specific implementation process of this utility model is as follows: In use, the mainboard of the AI ​​conference machine to be processed is first placed in the middle of the upper end of the tooling base 41. Then, the motor 2 drives the bidirectional screw 43 to rotate, so that the two moving seats 44 move towards each other, thereby clamping the mainboard in the horizontal direction. Moreover, during the process of the moving seats 44 moving towards each other, when the inclined seat 47 slides with the moving seat 44 to the bottom of the pressure plate 412, the preload of the spring 49 interacts with the inclined surface to automatically generate a vertical downward pressure, thereby using the L-shaped plate 46 to form a vertical constraint on the mainboard, thereby strengthening the positioning of the mainboard and making it less prone to loosening. When the mainboard is being processed at one station, the other station can be loaded and unloaded simultaneously. After the motor 2 drives the turntable 3 to rotate 180°, the station can be quickly switched, reducing the ineffective waiting time for mainboard processing and improving efficiency.
