Description

Technical Field

[0001] This utility model relates to the field of nickel-plated soft gold substrate processing technology, and in particular to a continuous loading and unloading assembly for processing electroplated nickel-plated soft gold substrates. Background Technology

[0002] Nickel-soft gold substrate processing refers to the process of first electroplating a thin layer of nickel onto the surface of an IC substrate, and then electroplating a layer of pure gold (soft gold) on top of that. This processing method aims to improve the conductivity, corrosion resistance, and contact performance of the substrate, making it particularly suitable for electronic devices that require high-quality connections.

[0003] In the processing of nickel-gold substrates, the first step is to precisely fix the substrate onto specially designed clamps. This step ensures the stability of the substrate during subsequent operations, preventing displacement or movement during electroplating. Then, workers sequentially hang the clamps containing the substrates onto support rods above the electroplating tank, forming an orderly arrangement for uniform electroplating. During electroplating, current flows through the electroplating solution, and the support rods, acting as a conductive medium, conduct the current to the clamps and then to the substrate. Under the influence of the current, metal ions (such as nickel and gold ions) in the electroplating solution undergo a reduction reaction on the substrate surface, reducing them to metal atoms which are then deposited on the substrate surface, forming uniform nickel and gold layers. This process utilizes the principle of electrolysis to construct a uniform and dense coating on the substrate surface, significantly improving its conductivity, corrosion resistance, and contact performance.

[0004] The shortcomings of the existing technical solutions are that the nickel-soft gold substrate electroplating operation is inefficient. This is mainly because the mounting and electroplating processes cannot be performed concurrently. Workers must first mount the substrates one by one onto the support rods; during this process, the substrates are in a waiting state and cannot begin electroplating. Electroplating can only begin after all substrates are mounted, leading to a prolonged overall production cycle. This sequential operation mode limits the throughput of the production line and increases time costs, especially when processing a large number of substrates, where the efficiency problem becomes more pronounced. Utility Model Content

[0005] This invention provides a continuous loading and unloading assembly for processing nickel-plated soft gold substrates, which can solve the problem of low electroplating efficiency in the existing nickel-plated soft gold substrate electroplating operation.

[0006] A continuous loading and unloading assembly for processing electroplated nickel-soft gold substrates includes a loading and unloading assembly, which includes a support member, the support member including a support frame, a rotating disk rotatably mounted on the support frame, and at least two sets of rotating rods fixedly connected at equal intervals around the side of the rotating disk; each set of rotating rods has a suspension rod perpendicular to the rotating rod at its end, and a drive device for driving the rotating disk to rotate is fixedly mounted on the support frame.

[0007] As a further embodiment of this utility model: the support member is provided in two sets, and the suspension rod in each set is disposed between the corresponding two sets of rotating rods.

[0008] As a further embodiment of this invention: each set of suspension rods is rotatably connected to a corresponding rotating rod.

[0009] As a further embodiment of this utility model, the surface of each set of suspension rods is roughened.

[0010] As a further embodiment of this utility model, each set of support frames is fixedly provided with a base at its bottom.

[0011] As a further embodiment of this utility model: the driving device includes a servo motor, which is fixedly mounted on a set of support frames.

[0012] As a further embodiment of this invention, the cross-section of the suspension rod is polygonal.

[0013] As a further embodiment of this utility model: each set of rotating disks has four sets of rotating rods equidistantly surrounding its side.

[0014] As a further embodiment of this utility model: the base is frustum-shaped and made of hard metal.

[0015] As a further embodiment of this utility model: the loading and unloading components are provided in two sets and are located on both sides of the electroplating tank.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, this utility model separates the hanging and electroplating, and the electroplating and unloading operations. When the electroplating tank is electroplating, the worker is responsible for hanging the fixed clamp on a set of suspension rods. When the electroplating is completed and the unloading is completed, the fixed clamp that has just been hung can be sent to the support rod through the loading and unloading assembly, and then electroplating is carried out again. The empty suspension rod will return to the worker and be hung again. That is, hanging, electroplating and unloading are carried out simultaneously, thereby improving the overall efficiency.

[0018] 2. When this utility model is in use, when the suspension rod makes a circular motion, the suspension rod will rotate with the rotating rod under the action of the fixed clamp, thereby avoiding the relative movement between the suspension rod and the fixed clamp, which would affect the loading state of the fixed clamp.

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] like Figures 1 to 5 As shown in the figure, this utility model provides a continuous loading and unloading assembly for processing electroplated nickel-soft gold substrates. The assembly includes a loading and unloading component, which in turn includes a support member. The support member includes a support frame 1, on which a rotating disk 4 is rotatably mounted. At least two sets of rotating rods 5 are equidistantly fixedly connected around the side of the rotating disk 4. For a detailed structure, please refer to [reference needed]. Figure 3 Each set of rotating rods 5 has a suspension rod 6 perpendicular to it at its end. Two sets of supports are provided, with each set of suspension rods 6 positioned between the corresponding two sets of rotating rods 5. A drive device 3 for rotating the rotating disk 4 is fixedly mounted on the support frame 1. The drive device is preferably a servo motor, facilitating precise control of the rotation speed and the stopping position of the suspension rod 6. The drive device 3 drives the rotating disk 4 to rotate, which in turn drives the rotating rods 5 to rotate. The rotating rods 5 then drive the suspension rods 6 to rotate along the axis of the rotating disk 4. The suspension rods 6 cause the fixed clamps 7 attached to the rotating rods 5 to perform circular motion.

[0028] The aforementioned fixing clamp 7 includes a clamp 703 for fixing a nickel-gold substrate. A forward hook 701 is fixedly mounted on the clamp 703, and a reverse hook 702 is fixedly mounted on the back of the forward hook 701, with the two sets of hooks facing opposite directions. In use, the nickel-gold substrate is fixed to the clamp 703, then the forward hook 701 is oriented towards the electroplating tank 8, and the reverse hook 702 is hung on the suspension rod 6, thus achieving the mounting of the nickel-gold substrate. The fixing clamp 7 is made of metal, or its surface is plated with a conductive metal layer.

[0029] It is important to understand that electrically operated telescopic components 9 are fixedly installed on both sides of the electroplating tank 8. A support rod 10 is fixedly connected to the output end of the electrically operated telescopic components 9. The support rod 10 must be made of a conductive material, such as stainless steel, copper alloy, or aluminum alloy, preferably stainless steel. A wire for conducting current is connected to the support rod 10. The electrically operated telescopic components 9 can drive the fixed clamp 7, which is mounted on the support rod 10, into the electroplating tank 8, thus enabling the operation of the electroplating tank 8. A fan 11 is installed above the electroplating tank 8 to blow away excess moisture from the nickel-gold substrate as much as possible, reducing the difficulty of subsequent drying.

[0030] like Figure 4 As shown, in practical applications, two sets of loading and unloading components are set up on both sides of the electroplating tank 8. One set of loading and unloading components is dedicated to loading, and the other set is dedicated to unloading. The operator hangs the fixing clamps 7 onto the suspension rods 6 of the previous loading and unloading component. The drive device 3 on this set of components drives the suspension rods 6 to rotate, causing all the fixing clamps 7 to rotate until all the forward hooks 701 on the fixing clamps 7 are hooked onto the support rod 10. The suspension rods 6 continue to rotate, thus disengaging from the backward hooks 702, completing the loading operation. During unloading, the suspension rods 6 in the dedicated unloading component are driven to rotate in the opposite direction to the rotation of the suspension rods 6 in the previous loading and unloading component. This allows the suspension rods 6 to enter the forward hook 701's hook opening, lifting the forward hook 701 and thus lifting the entire fixing clamp 7, achieving the effect of all the fixing clamps 7 disengaging together. This solution separates the mounting and electroplating, as well as the electroplating and unloading operations. When the electroplating tank 8 is electroplating, the staff is responsible for mounting the fixed clamps 7 on a set of suspension rods 6. After the electroplating and unloading are completed, the fixed clamps 7 that have just been mounted can be sent to the support rod 10 through the loading and unloading assembly, and then electroplating is carried out again. The empty suspension rods 6 will return to the staff and be mounted again. That is, mounting, electroplating and unloading are carried out simultaneously.

[0031] To prevent the suspension rod 6 from affecting the state of the fixed clamp 7 during its circular motion, each set of suspension rods 6 is rotatably connected to the corresponding rotating rod 5. When the suspension rod 6 moves in a circular motion, it will rotate relative to the rotating rod 5 under the action of the fixed clamp 7, thereby preventing relative movement between the suspension rod 6 and the fixed clamp 7.

[0032] In one specific embodiment, each set of suspension rods 6 has textures extending along the extension direction of the suspension rod 6 on its surface, which is used to increase the friction between the suspension rod 6 and the fixed clamp 7.

[0033] In one specific embodiment, the suspension rod 6 has a polygonal cross-section, which facilitates maintaining the relative position of the suspension rod 6 and the fixed clamp 7.

[0034] Each support frame 1 is fixedly equipped with a base 2 at its bottom. The base 2 is frustum-shaped and preferably made of hard metal. The metal base 2 maintains the stability of the support frame 1 and prevents shaking during loading and unloading.

[0035] In another specific embodiment, each set of rotating disks 4 is surrounded by four sets of rotating rods 5 at equal intervals on its sides. By increasing the number of rotating rods 5, the buffer time is increased. When the loading work on a set of suspension rods 6 is not yet completed, the drive device 3 drives the set of suspension rods 6 to rotate, and the set of suspension rods 6 will not send the fixed clamp 7 on the suspension rod 6 to the support rod 10, so that the workers can adjust their time in time to replenish the fixed clamp 7 on the suspension rod 6.

[0036] Working principle: When in use, the operator fixes the nickel soft gold carrier plate to the clamp 703, then makes the forward hook 701 face the electroplating tank 8, and hangs the reverse hook 702 on the suspension rod 6 to realize the mounting of the nickel soft gold carrier plate.

[0037] The drive unit 3 drives the suspension rod 6 to rotate, causing all the fixed clamping plates 7 to rotate until all the forward hooks 701 on the fixed clamping plates 7 are hooked onto the support rod 10. The suspension rod 6 continues to rotate, thereby disengaging from the reverse hook 702, thus completing the loading operation. During unloading, the suspension rod 6 in the loading and unloading assembly dedicated to unloading is driven to rotate, and the rotation direction is opposite to the rotation direction of the suspension rod 6 in the previous loading and unloading assembly. This allows the suspension rod 6 to enter the hook opening of the forward hook 701, then lifts the forward hook 701, thereby lifting the entire fixed clamping plate 7, completing the effect of all the fixed clamping plates 7 disengaging together.

[0038] This solution separates the hanging and electroplating, and the electroplating and unloading operations. When the electroplating tank 8 is electroplating, the staff is responsible for hanging the fixed clamp 7 on a set of suspension rods 6. When the electroplating is completed and the unloading is completed, the fixed clamp 7 that has just been hung can be sent to the support rod 10 through the loading and unloading assembly, and then electroplating is carried out again. The empty suspension rod 6 will return to the staff and be hung again. That is, hanging, electroplating and unloading are carried out simultaneously, thereby improving the overall efficiency.

[0039] When the suspension rod 6 makes a circular motion, the suspension rod 6 will rotate with the rotating rod 5 under the action of the fixed clamp 7, thereby avoiding the relative movement between the suspension rod 6 and the fixed clamp 7 and affecting the loading state of the fixed clamp 7.

[0040] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
