Description

Technical Field

[0001] This utility model relates to the field of network transformer manufacturing technology, and in particular to a network transformer clamping module. Background Technology

[0002] Against the backdrop of the rapid development of modern electronic communication technology, network transformers, as key electronic components for realizing network signal transmission, isolation and impedance matching, are widely used in various network devices such as routers, switches, and network cards. Their performance stability and production efficiency directly affect the quality and production capacity of downstream electronic equipment.

[0003] The production process of network transformers is complex, involving multiple key steps such as winding, assembly, and welding. Among these, the tinning of transformer pins is a crucial process to ensure the reliability of their electrical connections. To improve the welding quality of the pins and avoid problems such as cold solder joints and false solder joints, the pins need to be immersed in flux before tinning. The flux removes the oxide layer on the surface of the pins and enhances the fluidity and adhesion of the solder.

[0004] Currently, the industry generally adopts an automated production mode for the tinning and flux soaking processes of network transformers. This involves using robotic arms to drive clamping modules to grab and transfer network transformers, thereby achieving continuous processing.

[0005] However, existing clamping modules have significant drawbacks in practical applications: Current positioning clamping achieves positioning by creating a through-slot on the clamping base, within which the network transformer is embedded. This design results in large-area contact between the side walls and bottom of the network transformer and the inner wall of the through-slot. This leads to excessive flux sticking to the contact points between the clamping base and the network transformer during the flux soaking process; furthermore, after the subsequent tinning process, as the flux solidifies or residual solder adheres, the network transformer often becomes difficult to separate smoothly from the clamping base. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a network transformer clamping module.

[0007] A network transformer clamping module designed for this purpose includes a mounting base, a clamping base, a magnet, and a linear motion module;

[0008] The clamping seat is fixedly mounted on the mounting base; the lower surface of the clamping seat is provided with several rows of positioning parts arranged from left to right, forming a fixing space for fixing the network transformer between two adjacent rows of positioning parts; the fixing space is provided with a longitudinal through-hole penetrating the clamping seat;

[0009] The magnet is positioned above the clamping base to attract the network transformer;

[0010] The linear motion module is used to drive the magnet to move longitudinally relative to the mounting base.

[0011] Preferably, each row of positioning parts has two positioning parts, and the two positioning parts are arranged at an interval.

[0012] Preferably, the wall surface of the positioning part facing the fixed space is an inclined surface.

[0013] Preferably, the mounting base is provided with a longitudinal movement space, and the magnet is disposed within the longitudinal movement space.

[0014] Preferably, the linear motion module includes a linear element fixedly mounted on the mounting base and a movable base connected to the telescopic shaft of the linear element, and the magnet is fixedly mounted on the movable base.

[0015] Compared with the prior art, the network transformer clamping module provided by this invention has significant advantages:

[0016] First, by setting multiple rows of positioning parts on the lower surface of the clamping seat, the fixed space formed between adjacent positioning parts can accurately limit the positioning of the network transformer. Combined with the adsorption effect of the magnet, the network transformer can be stably fixed during the transfer process, effectively preventing it from shaking or shifting, and ensuring the processing accuracy of processes such as tinning and flux soaking.

[0017] Secondly, a longitudinal through-hole is provided within the fixed space to significantly reduce the contact area between the clamp and the network transformer. This design can significantly reduce the probability of flux sticking to the contact area, while avoiding adhesion problems caused by residual solder. This allows the network transformer to be easily separated from the clamping module after processing, reducing quality problems such as shell damage and pin deformation caused by forced separation, and lowering the defect rate.

[0018] Furthermore, the linear motion module can move the magnet longitudinally relative to the mounting base. By adjusting the distance between the magnet and the network transformer, the magnitude of the adsorption force can be flexibly controlled. When it is necessary to place the network transformer, simply moving the magnet away will quickly release the adsorption, making the operation convenient and efficient, and helping to improve the overall efficiency of automated production.

[0032] See Figures 1-5 A network transformer clamping module includes a mounting base 10, a clamping base 20, a magnet 30, and a linear movement module 40. The clamping base 20 is fixedly mounted on the mounting base 10. The lower surface of the clamping base 20 has several rows of positioning parts 210 arranged horizontally, forming a fixing space 220 for fixing a network transformer 60 between adjacent rows of positioning parts 210. The fixing space 220 has a through-hole 230 that extends longitudinally through the clamping base 20. The magnet 30 is disposed above the clamping base 20 and is used to attract the network transformer 60. The linear movement module 40 is used to drive the magnet 30 to move longitudinally relative to the mounting base 10.

[0033] The working principle of this network transformer clamping module is as follows:

[0034] During the gripping operation of the network transformer, the mounting base 10 is mounted on the robotic arm, and the entire module moves synchronously with the movement of the robotic arm. During operation, the linear motion module 40 first moves the magnet 30 downward, bringing it closer to the gripper 20. When the robotic arm moves the mounting base 10 and the gripper 20 above the network transformer 60, the network transformer 60 is aligned with the fixed space 220 formed by two adjacent rows of positioning parts 210 on the lower surface of the gripper 20. At this time, the magnetic force generated by the magnet 30 passes through the gripper 20 and acts on the network transformer 60, attracting it and embedding it into the fixed space 220. The positioning parts 210 provide lateral limiting for the network transformer 60, ensuring its stability within the fixed space 220.

[0035] During the process of transferring the network transformer 60 for tinning or flux immersion, the robot arm moves the mounting base 10 and the entire module. The magnet 30 maintains the adsorption state of the network transformer 60. With the limiting of the positioning part 210, the network transformer 60 is effectively prevented from shaking or falling off during movement. At the same time, the opening 230 in the fixed space 220 reduces the contact area between the clamping base 20 and the network transformer 60, reducing the risk of adhesion.

[0036] When the network transformer 60 needs to be placed in the designated position, the robot arm moves the module to above the target position. The linear moving module 40 moves the magnet 30 upward, away from the clamping seat 20. At this time, the attraction force of the magnet 30 on the network transformer 60 weakens until it disappears. Under its own weight or a slight external push, the network transformer 60 is detached from the fixed space 220, completing the placement action.

[0037] In this invention, each row of positioning parts 210 has two positioning parts 210, and the two positioning parts 210 are arranged with a front-to-back interval. Alternatively, one or three positioning parts 210 can be set according to different positioning and fixing requirements, and the number of positioning parts 210 in each row can be set according to different requirements.

[0038] See Figure 3 The wall of the positioning part 210 facing the fixed space 220 is set as an inclined surface 211. When the network transformer 60 is embedded in the fixed space 220, the inclined surface can guide it to quickly and accurately lock into the predetermined position, reducing alignment deviation. When the network transformer 60 is detached, the inclined surface can reduce contact resistance, avoid jamming caused by the corners, and make the separation smoother.

[0039] In this utility model, an interval space 240 is provided between two adjacent fixed spaces 220, which can prevent adjacent network transformers 60 from contacting or colliding with each other during the gripping, transfer and processing process, and prevent problems such as shell damage and pin deformation caused by squeezing. At the same time, it provides space for the liquid flow and excess liquid dripping in the flux soaking and tinning process, reduces mutual interference between different network transformers and ensures processing quality.

[0040] See Figure 3 and Figure 5 The mounting base 10 is provided with a longitudinal movement space 100, and the magnet 30 is disposed within the longitudinal movement space 100. The longitudinal movement space 100 within the mounting base 10 provides a dedicated activity area for the magnet 30, which not only guides and limits the longitudinal movement of the magnet 30, ensuring its stable movement trajectory and preventing deviation from affecting the adsorption effect, but also houses the magnet 30, making the overall structure more compact and reducing interference from external factors on the magnet 30.

[0041] See Figure 2 and Figure 5 The linear motion module 40 includes a linear element 410 fixedly mounted on the mounting base 10 and a movable base 420 connected to the telescopic shaft of the linear element 410. The magnet 30 is fixedly mounted on the movable base 420. During operation, the linear element 410 fixed on the mounting base 10 can drive the movable base 420 to move longitudinally via the telescopic shaft, thereby driving the magnet 30 fixed on the movable base 420 to move synchronously. This allows for precise adjustment of the distance between the magnet 30 and the clamping base 20 and the network transformer 60, achieving flexible control of the adsorption force and meeting different needs for gripping and placement.

[0042] In this invention, the linear element 410 is a cylinder or a linear motor.

[0043] In this invention, a lifting cylinder 510 is provided on one side of the mounting base 10, and an insertion-type liquid level gauge 520 is fixedly connected to the telescopic shaft of the lifting cylinder 510. The lifting cylinder 510 can drive the insertion-type liquid level gauge 520 to move up and down flexibly, facilitating the adjustment of the insertion depth of the liquid level gauge according to actual processing needs, and accurately monitoring the liquid level of flux or molten solder. This provides real-time feedback on the liquid level status, avoiding excessive immersion of the network transformer due to excessively high liquid levels, or affecting the immersion of solder or flux due to excessively low liquid levels, ensuring processing consistency; at the same time, it can promptly remind the replenishment of materials, reducing production interruptions caused by abnormal liquid levels, and improving production continuity and stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
