Description

Technical Field

[0001] This utility model relates to the field of LDS antenna processing technology, specifically to an auxiliary device for LDS antenna processing. Background Technology

[0002] Electroless nickel plating, also known as electroless nickel plating or autocatalytic nickel plating, is a plating method in which nickel ions in the plating solution are reduced to metallic nickel and deposited onto the surface of the part without the application of an external current, using a suitable reducing agent. It is commonly used for nickel plating on tubular or small parts with complex shapes, and no polishing is required afterward. Currently, most mobile phone LDS antennas on the market are nickel-plated using electroless nickel plating.

[0003] As indicated by announcement number CN221988668U, a chemical nickel plating apparatus for LDS antenna processing is described. The apparatus includes a nickel plating pool, with support plates fixedly connected to both sides of the nickel plating pool. Slide plates are fixedly installed on the top of each of the two support plates. Positioning blocks are slidably connected to the outer surfaces of each of the two slide plates. Mounting plates are fixedly connected to one side of each of the two positioning blocks. Placement plates are fixedly connected to one side of each of the two mounting plates at their lower edges. Four placement through holes are provided at the top of the placement plates.

[0004] The aforementioned device lacks a stirring component during use, which prevents the plating solution from mixing evenly, easily leading to uneven reaction and affecting the uniformity and quality of the LDS antenna coating for mobile phones. It also slows down the reaction speed, affecting production efficiency. Therefore, we propose an auxiliary device for LDS antenna processing to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for LDS antenna processing, so as to solve the problem mentioned in the background art that the existing chemical nickel plating device for LDS antenna processing lacks a stirring component during use, which cannot make the plating solution mix evenly, easily leading to uneven reaction, affecting the uniformity and quality of the LDS antenna coating for mobile phones, and also slowing down the reaction speed, thus affecting production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for LDS antenna processing, comprising a reaction chamber, an inner cavity inside the reaction chamber, a first drive motor mounted on the outer bottom of the reaction chamber, a coupling mounted on the inner bottom of the reaction chamber, the coupling being located on the output shaft of the first drive motor, a stirring rod mounted on the top of the coupling, a plurality of stirring blades mounted on the outer wall of the stirring rod, the stirring blades being evenly distributed on the stirring rod, and heating wires wound around the outer wall of the stirring blades. An mounting plate is installed on the upper part of the side, and a column is installed on the top of the mounting plate. A vertical groove is provided inside the column on the side near the inner cavity. A lead screw is installed inside the vertical groove. A second drive motor is installed on the top of the lead screw through the column. A nut seat is threaded to the outer wall of the lead screw. A fixing rod is installed on the side of the nut seat near the inner cavity. The fixing rod is an L-shaped rod. A U-shaped frame is installed at the bottom of the other end of the fixing rod. A return spring is installed on the inner top and inner bottom of the U-shaped frame. A clamping plate is installed on one end of the two opposite faces of the return springs.

[0007] Preferably, a top cover is movably installed on the top of the reaction chamber.

[0008] Preferably, connecting rods are installed on both sides of the coupling, and baffles are installed on the top of both sides of the connecting rods.

[0009] Preferably, a temperature sensor is installed on the upper part of the other side of the reaction chamber, and the temperature sensor penetrates one side of the outer wall of the reaction chamber.

[0010] Preferably, a heat insulation layer is provided between the reaction chamber and the inner cavity.

[0011] Preferably, the inner surface of the cavity is uniformly coated with a polytetrafluoroethylene layer.

[0012] Preferably, the clamping plate has several sets of through holes inside.

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

[0014] This invention uses a first drive motor to rotate a coupling, which in turn rotates a stirring rod to rotate stirring blades, ensuring uniform mixing of the chemical plating solution. This facilitates subsequent processing of mobile phone LDS antennas. A heating wire heats the chemical plating solution, improving processing efficiency. A temperature sensor continuously monitors the temperature inside the reaction chamber, allowing for timely temperature adjustments to maintain a constant temperature. The coupling also drives a connecting rod, which in turn rotates a baffle plate, further promoting uniform mixing and flow of the solution. This prevents concentration and temperature differences, resulting in a solution with uniform concentration and temperature. This invention solves the problem of existing chemical nickel plating devices for LDS antenna processing lacking a stirring component, leading to uneven mixing, inconsistent reaction, and compromised uniformity and quality of the LDS antenna plating. It also slows down the reaction rate, impacting production efficiency. Attached Figure Description

[0020] 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.

[0021] It promotes the flow of the plating solution, prevents concentration and temperature differences within the solution, and facilitates obtaining a plating solution with uniform concentration and temperature.

[0022] Please see Figure 1-4 This utility model provides an embodiment of an auxiliary device for LDS antenna processing, comprising a reaction chamber 1, an inner cavity 2 containing a chemical plating solution, a first drive motor 4 mounted on the bottom of the reaction chamber 1, and a coupling 5 mounted on the bottom of the reaction chamber 1, the coupling 5 being located on the output shaft of the first drive motor 4. A stirring rod 6 is mounted on the top of the coupling 5, and several sets of stirring blades 7 are mounted on the outer wall of the stirring rod 6, the stirring blades 7 being evenly distributed on the stirring rod 6. The first drive motor 4 can drive the coupling 5 to rotate, thereby rotating the stirring blades 7 through the rotation of the stirring rod 6, which can make the chemical plating solution uniformly mixed, facilitating subsequent processing. Continuing the processing of the mobile phone LDS antenna, a heating wire 8 is wound around the outer wall of the stirring blade 7. Connecting rods 9 are installed on both sides of the coupling 5, and baffles 10 are installed on the top of both sides of the connecting rods 9. A temperature sensor 11 is installed on the upper part of the other side of the reaction chamber 1. The temperature sensor 11 penetrates one side of the outer wall of the reaction chamber 1. The heating wire 8 can heat the chemical plating solution, which can improve the processing efficiency of the mobile phone LDS antenna. The temperature sensor 11 can detect the internal temperature of the reaction chamber 1 at any time, which facilitates timely adjustment of the internal temperature of the reaction chamber 1 to ensure that the chemical plating solution is in a constant temperature state. The coupling 5 can drive the connecting rods 9 to rotate, thereby driving the baffles 10 to rotate. To further ensure uniform mixing of the electroless plating solution, promote its flow, and prevent concentration and temperature differences, thus facilitating the acquisition of a plating solution with uniform concentration and temperature, a mounting plate 14 is installed on the upper part of one side of the reaction tank 1. A column 15 is installed on the top of the mounting plate 14. A vertical groove 16 is provided inside the column 15 near the inner cavity 2. A lead screw 17 is installed inside the vertical groove 16. A second drive motor 18 is installed on the top of the lead screw 17 through the column 15. A nut seat 19 is threaded onto the outer wall of the lead screw 17. A fixing rod 20 is installed on the side of the nut seat 19 near the inner cavity 2. The fixing rod 20 is an L-shaped rod. A U-shaped frame 21 is installed at the bottom of the other end of the fixing rod 20. Both the inner top and inner bottom of component 1 are equipped with return springs 22. A clamping plate 23 is installed at one end of the opposite face of the two return springs 22. The clamping plate 23 has several sets of through holes 24 inside. The mobile phone LDS antenna to be processed is placed between the two clamping plates 23. The mobile phone LDS antenna can be fixed and clamped by the continuous reaction force of the two return springs 22, which improves the stability of the parts during the chemical plating process and improves the product qualification rate. The second drive motor 18 drives the lead screw 17 to rotate, causing the nut seat 19 to move down. This causes the U-shaped frame 21 to move down into the inner cavity 2 through the fixing rod 20, so that the mobile phone LDS antenna can fully contact the chemical plating solution for chemical plating processing.

[0023] Please see Figure 4The top of the reaction chamber 1 is movably fitted with a top cover 3, which can be removed as needed, improving the practicality of the device. This effectively reduces the oxidation reaction of the reducing agent, ensures the quality of the plating solution, and reduces the entry of air and dust.

[0024] Please see Figure 4 A heat insulation layer 12 is provided between the reaction chamber 1 and the inner cavity 2. The heat insulation layer 12 can effectively maintain the temperature stability inside the reaction chamber 1, ensure the stability of the reaction and the quality of the mobile phone LDS antenna coating, and reduce the production line downtime caused by temperature fluctuations.

[0025] Please see Figure 4 The inner surface of the inner cavity 2 is uniformly coated with a polytetrafluoroethylene layer 13, which gives the reaction chamber 1 good versatility, corrosion resistance and reliability. It can hold chemical plating solutions with different acidity and alkalinity, which improves the practicality of the device and makes it easier to meet different usage needs.
