[0005]更为关键的是,由于夹持座为一体式固定结构,其前后两侧无法实现主动张开动作,当完成浸锡进入下料环节时,即便粘黏部位形成较强附着力,也无法通过扩大夹持通道间距来消除粘黏影响,进而导致网络变压器难以与夹持座分离
[0020] First, flux adhesion is significantly reduced. By designing the clamping components as two independent structures spaced back-to-back, with the clamping parts on each component arranged horizontally and spaced apart, the contact area between the clamping mechanism and the network transformer can be significantly reduced. Compared to the large-area contact of traditional integrated clamping channels, this structure reduces flux accumulation in the contact area. Especially for thinner network transformers, it reduces the risk of adhesion caused by overall immersion, reducing resistance during material handling from the outset.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of network transformer manufacturing technology, and in particular to a network transformer clamping mechanism. Background Technology
[0002] In the manufacturing of network communication equipment, network transformers, as key components for signal transmission, electrical isolation, and impedance matching, directly affect the performance and stability of terminal equipment through their manufacturing precision and efficiency. Among these processes, the tinning of transformer pins is a crucial step in the network transformer production process. This step, by forming a uniform and robust tin layer on the pin surface, ensures conductivity and connection reliability during subsequent soldering, making it one of the core procedures for guaranteeing the electrical performance of the network transformer.
[0003] To ensure effective soldering, the transformer pins must be immersed in flux before the soldering process. Flux removes the oxide layer from the pin surface and reduces the surface tension of the molten solder, thus promoting uniform solder adhesion. Currently, the industry commonly uses automated production to complete these processes. A robotic arm drives a clamping module to pick up the network transformer and sequentially perform flux immersion, soldering, and subsequent transfer operations along a preset trajectory. While this automation significantly improves production efficiency, there are still technical challenges that need to be addressed in practical applications.
[0004] Specifically, the existing clamping module's clamping base structure has significant design limitations: it is a one-piece structure with an internal clamping channel open at the bottom. During operation, the network transformer is attracted and fixed in the clamping channel by built-in magnetic elements. In this structure, the front and rear walls of the network transformer are tightly fitted to the front and rear walls of the clamping channel, resulting in a significantly increased contact area. During the flux immersion process, flux easily adheres to these large contact areas. More importantly, due to differences in network transformer specifications, when flux immersion is performed on thinner transformers, most of the transformer is submerged in flux, further exacerbating the accumulation and adhesion of flux in the contact area between the network transformer and the clamping channel walls.
[0005] More importantly, because the clamping base is a one-piece fixed structure, its front and rear sides cannot be actively opened. When the tinning process is completed and the material is unloaded, even if strong adhesion is formed at the adhesive parts, the adhesion effect cannot be eliminated by widening the clamping channel spacing, making it difficult to separate the network transformer from the clamping base. This problem not only causes production stoppages and reduces production efficiency, but may also cause transformer pin deformation and component damage due to forced separation operations, seriously affecting product quality and production yield.
[0006] Therefore, in order to address the separation problem of existing clamps during the tin-dip processing of network transformers, it is urgent to propose an improvement scheme to optimize the production process and enhance product reliability. Utility Model Content
[0007] 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 mechanism.
[0008] A network transformer clamping mechanism designed for this purpose includes a fixed base, a clamping component, a magnetic attraction element, a driving element, and a linear driving element;
[0009] The clamping member is provided in two parts and is spaced apart from one another, forming a clamping channel with an opening on the lower side between the two clamping members; the clamping member is provided with a plurality of clamping parts arranged in the left-right direction, and the clamping parts extend downward relative to the clamping member; a gap space is provided between two adjacent clamping parts;
[0010] The magnetic attraction element is longitudinally movable relative to the fixed base and is used to attract the network transformer into the clamping channel;
[0011] The driving element is fixedly mounted on the fixed base and connected to the two clamping members. The driving element is used to drive the two clamping members to move closer to each other or further away from each other.
[0012] The linear drive element is fixedly mounted on the fixed base and fixedly connected to the magnetic attraction element. The linear drive element is used to drive the magnetic attraction element to move longitudinally relative to the fixed base.
[0013] Preferably, the clamping part is provided with an abutment part facing the wall of the clamping channel.
[0014] Preferably, the driving element is a parallel pneumatic gripper, and the two moving ends of the parallel pneumatic gripper are fixedly connected to two clamping members respectively.
[0015] Preferably, there are two driving elements arranged at an interval between them.
[0016] Preferably, the magnetic element includes a movable base and a magnet fixedly installed in the movable base; the movable base is connected to the linear drive element.
[0017] Preferably, the linear drive element is a cylinder or a linear motor.
[0018] Preferably, a lifting cylinder is provided on one side of the fixed base, and an insertion level gauge is fixedly connected to the cylinder shaft of the lifting cylinder.
[0019] Compared with the prior art, the network transformer clamping mechanism described in this invention can effectively solve the problem of adhesion and separation of existing clamping seats during the production process, and has the following significant advantages:
[0020] First, flux adhesion is significantly reduced. By designing the clamping components as two independent structures spaced back-to-back, with the clamping parts on each component arranged horizontally and spaced apart, the contact area between the clamping mechanism and the network transformer can be significantly reduced. Compared to the large-area contact of traditional integrated clamping channels, this structure reduces flux accumulation in the contact area. Especially for thinner network transformers, it reduces the risk of adhesion caused by overall immersion, reducing resistance during material handling from the outset.
[0021] Secondly, it achieves flexible separation and efficient unloading. By using a driving element to move the two clamping components closer together or further apart, it overcomes the limitation of traditional integrated structures that cannot open. During the unloading process after tinning, the driving element controls the clamping components to open outwards, actively eliminating adhesion at the sticky parts. This allows the network transformer to detach smoothly without external force, avoiding pin deformation or component damage caused by forced separation, thus ensuring product quality and production continuity.

[0033] See Figures 1-3A network transformer clamping mechanism includes a fixed base 10, clamping members 20, a magnetic attraction element 30, a driving element 40, and a linear driving element 50. Two clamping members 20 are provided and spaced apart, forming a clamping channel 200 with an opening on the lower side between the two clamping members 20. Several clamping portions 210 are arranged along the left-right direction on each clamping member 20, and each clamping portion 210 extends downward relative to the clamping member 20. A space 230 is provided between adjacent clamping portions 210. The magnetic attraction element 30... The clamping element 40 is longitudinally movable relative to the fixed base 10 and is used to attract the network transformer 100 into the clamping channel 200; the driving element 40 is fixedly mounted on the fixed base 10 and connected to the two clamping members 20, and the driving element 40 is used to drive the two clamping members 20 to move closer or further apart; the linear driving element 50 is fixedly mounted on the fixed base 10 and fixedly connected to the magnetic attraction element 30, and the linear driving element 50 is used to drive the magnetic attraction element 30 to move longitudinally relative to the fixed base 10.
[0034] The working principle of the network transformer clamping mechanism is as follows:
[0035] The fixed base 10 moves with the robot arm. When it grasps the network transformer 100, the linear drive element 50 drives the magnetic attraction element 30 to move downward and attract the network transformer 100. After the attraction is completed, the drive element 40 drives the two clamping parts 20 to move closer together and clamps the attracted network transformer 100 through the clamping parts 210.
[0036] During unloading, the linear drive element 50 first drives the magnetic attraction element 30 to move upward to release the attraction, and then the drive element 40 drives the two clamping parts 20 to move away from each other and spread out, so that the network transformer 100 is released.
[0037] See Figure 2 The clamping part 210 is provided with an abutment part 220 facing the wall of the clamping channel 200. When clamping the network transformer 100, it can fit against the upper surface of the network transformer 100 to achieve abutment and limit. At the same time, by increasing the contact area to a certain extent, the stability of clamping is ensured.
[0038] In this utility model, the driving element 40 adopts a parallel pneumatic gripper, whose two moving ends are fixedly connected to two clamping parts 20 respectively. It can stably output driving force and accurately drive the two clamping parts 20 to achieve relative movement of moving closer or further away from each other, thereby reliably completing the clamping and releasing action of the network transformer 100. It also has a fast response speed and is suitable for the rhythm of automated production.
[0039] In addition to parallel pneumatic grippers, a gear and rack mechanism can also be used. The motor drives the gear to rotate, which in turn drives the two racks meshing with it to move in opposite directions. The racks are then connected to the grippers to achieve relative movement between the two grippers. Alternatively, a bidirectional screw and slider mechanism can be used. The motor drives the bidirectional screw to rotate, which causes the two sliders mounted on the screw to move towards or away from each other. The sliders are connected to the grippers and drive the grippers to move.
[0040] In this invention, two driving elements 40 are provided and spaced apart from each other on the left and right. The two driving elements 40, distributed alternately on the left and right, can apply driving force to the two clamping members 20 from different positions on the left and right. This arrangement enhances the stability and balance of the driving force, avoiding problems such as uneven force distribution and skewed movement that may occur when a single driving element is used. It ensures that the two clamping members 20 remain synchronized as they approach or move away from each other, thereby guaranteeing the accuracy and reliability of clamping the network transformer 100. This is particularly suitable for scenarios where multiple clamping parts 210 operate simultaneously, improving the overall operational stability of the mechanism.
[0041] See Figures 1 to 3 The magnetic attraction element 30 includes a movable base 310 and a magnet 320 fixedly installed within the movable base 310; the movable base 310 is connected to the linear drive element 50. The magnet 320 generates magnetic force, stably attracting the network transformer 100 and providing reliable attraction force for the grasping process. The movable base 310, connected to the linear drive element 50, can move longitudinally under the drive of the linear drive element 50, thereby moving the magnet 320 closer to or away from the network transformer 100, flexibly completing the attraction and release actions, and ensuring precise control over the grasping and releasing of the network transformer 100.
[0042] In this invention, the linear drive element 50 is a cylinder or a linear motor.
[0043] See Figure 1 A lifting cylinder 610 is provided on one side of the fixed base 10, and an insertion level gauge 620 is fixedly connected to the cylinder shaft of the lifting cylinder 610. The lifting cylinder 610, with its cylinder shaft fixedly connected to the insertion level gauge 620, can drive the insertion level gauge 620 to move up and down. This allows the insertion level gauge 620 to extend into or out of containers such as flux pools and solder pools as needed, accurately monitoring the level of flux or solder, so as to replenish materials in a timely manner, avoiding the impact of insufficient liquid level on the immersion soldering and fluxing effects, and ensuring the stability and consistency of network transformer production and processing.
