Description

Technical Field

[0001] This utility model relates to the field of electroplating fixture technology, and in particular to a material conveying and lifting fixture. Background Technology

[0002] In the manufacturing of precision components such as electronic components, connectors, and semiconductor lead frames, localized electroplating is a critical process. This process requires immersing only specific portions (usually the lower end) of the continuously arranged terminals on the strip into the electroplating solution for deposition, while the main body of the strip and other parts must remain suspended to avoid unnecessary plating contamination and material waste, thereby ensuring the electrical performance and soldering reliability of the product. In this type of operation, the strip needs to be smoothly lifted and horizontally conveyed, precisely passing over the electroplating tank. The stability of its conveying and the accuracy of its position directly determine the precision and consistency of the electroplating area. Currently common solutions such as roller sets and clamps cannot simultaneously meet the multiple requirements of gentle clamping, stable conveying, and height adjustment, thus becoming a bottleneck for improving electroplating quality and production efficiency.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a material conveyor lifting fixture to solve the above problems.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art. It should not be assumed that the above content is known to those skilled in the art simply because it has been described in the background section of this utility model. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the present invention discloses a material conveying and lifting fixture that can achieve flexible, stable, adjustable, non-destructive clamping and precise positioning of thin material strips, so as to meet the needs of modern high-precision electroplating production.

[0006] This utility model discloses a material conveyor lifting fixture, including a lifting assembly. The moving end of the lifting assembly is connected to a cantilever in a horizontal direction. A fixed wheel shaft is vertically arranged at the lower end of the cantilever, and a directional wheel is rotatably mounted at the lower end of the fixed wheel shaft. A moving wheel shaft is mounted on the cantilever through a hinge structure. The moving wheel shaft is located on one side of the fixed wheel shaft, and the moving wheel shaft can swing around the hinge point towards the directional wheel. A moving wheel is rotatably mounted at the lower end of the moving wheel shaft. An elastic element is provided between the moving wheel shaft and the cantilever to force the moving wheel shaft to swing towards the directional wheel. The wheel surface of the moving wheel can form a V-shaped clamp with the wheel surface of the directional wheel at an angle. A lifting slider is also installed on the cantilever. A limit shaft is horizontally arranged on the lifting slider, and a limit wheel is rotatably connected to the limit shaft. The wheel surface of the limit wheel is corresponding to the V-shaped clamp.

[0007] Preferred technical solution: A vertical slide rail is provided on the cantilever, and the lifting slider is installed on the vertical slide rail in an adjustable height by means of locking bolts.

[0008] Preferred technical solution: The center point of the wheel surface of the limiting wheel and the center line of the V-shaped clamp are in the same vertical plane.

[0009] Preferred technical solution: A V-shaped groove for guiding the electroplating strip is provided on the surface of the limiting wheel.

[0010] Preferred technical solution: The hinge structure is a pin that passes through the upper end of the drive wheel shaft and the cantilever.

[0011] Preferred technical solution: The elastic element is a compression spring, and the two ends of the compression spring abut against the side wall of the drive wheel shaft 5 and the side wall of the cantilever, respectively.

[0012] Preferred technical solution: The wheel surface of the driving wheel is made of an elastic material.

[0013] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0014] This invention utilizes a V-shaped clamp formed by a moving wheel and a directional rotating wheel. The width of the V-shaped clamp is adjusted by the swing of the moving wheel shaft to adapt to material strips of different thicknesses. The V-shaped clamp squeezes and lifts the material strip upwards, while an adjustable height limiting wheel restricts the rise of the material strip from above, ensuring the stability of the material strip height. Its structure is simple, easy to operate, and suitable for high-speed continuous automated electroplating production lines. The moving wheel is made of elastic material to prevent damage to the surface of the material strip and its terminals when the V-shaped clamp squeezes and lifts the material strip upwards.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a material conveyor lifting fixture. The main components of this utility model will be described in detail below:

[0027] The fixture includes a lifting assembly 1 for controlling the height of the entire fixture. The moving end of the lifting assembly 1 is fixedly connected to a cantilever 2 in the horizontal direction.

[0028] A fixed wheel shaft 3 is vertically fixedly installed at the lower end of the cantilever 2. A directional wheel 4 is rotatably installed at the lower end of the fixed wheel shaft 3 through a bearing, and the position of the directional wheel 4 is fixed.

[0029] On the cantilever 2, a movable wheel shaft 5 is mounted on one side of the fixed wheel shaft 3 via a hinge structure. In this embodiment, the hinge structure uses a pin 11, which passes through the upper end of the movable wheel shaft 5 and the corresponding mounting lug on the cantilever 2, allowing the movable wheel shaft 5 to swing around the axis of the pin 11 (i.e., the hinge point) toward the directional wheel 4. A movable wheel 6 is also rotatably mounted on the lower end of the movable wheel shaft 5 via a bearing, and the movable wheel 6 is correspondingly positioned to the wheel face of the directional wheel 4.

[0030] An elastic element 7 is installed between the rotating shaft 5 of the drive wheel and the side wall of the cantilever 2. In this embodiment, the elastic element 7 is a compression spring, with its two ends abutting against the side wall of the rotating shaft 5 and the side wall of the cantilever 2, respectively. The compression spring continuously provides a spring force that forces the rotating shaft 5 to swing towards the directional wheel 4, thereby causing the wheel surface of the drive wheel 6 to press against the wheel surface of the directional wheel 4 at an angle, and the two together form a V-shaped clamp for holding the strip. Since the drive wheel 6 can swing and is driven by elastic force, the V-shaped clamp can adapt to strips of different thicknesses and provide flexible clamping force. Preferably, the wheel surface of the drive wheel 6 is made of an elastic material such as polyurethane to protect the surface of the strip and the terminals thereon.

[0031] A lifting slider 8 is also installed on the cantilever 2. Specifically, a vertical slide rail is provided on the cantilever 2, and the lifting slider 8 is located within the vertical slide rail and can slide up and down along the slide rail. The lifting slider 8 can be fixed at any height position on the cantilever 2 by locking bolts, thereby realizing height adjustment.

[0032] A limiting shaft 9 is horizontally mounted on the lifting slider 8, and a limiting wheel 10 is rotatably connected to the limiting shaft 9 via a bearing. The wheel surface of the limiting wheel 10 corresponds to the V-shaped clamp, and the center point of its wheel surface and the center line of the clamping seam of the V-shaped clamp are in the same vertical plane to ensure accurate and unbiased limiting of the material belt. Preferably, a V-shaped groove 10a is formed on the wheel surface of the limiting wheel 10. This groove can better accommodate and guide the material belt, preventing lateral deviation of the material belt during conveying.

[0033] Working principle:

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the conveyor belt passes through the V-shaped clamp formed by the moving wheel 6 and the directional wheel 4. The elastic element 7 pushes the moving wheel 6 to press the conveyor belt against the directional wheel 4, and the V-shaped clamp generates an upward force on the conveyor belt, lifting it up. After being lifted, the upper part of the conveyor belt contacts the surface of the limiting wheel 10, which prevents the conveyor belt from rising further, thus stabilizing the conveyor belt at a fixed height for conveying. By adjusting the height of the lifting slider 8, the final lifting height of the conveyor belt can be precisely controlled to adapt to different process requirements. Its structure is simple, its conveying stability is high, and it can adapt to conveying conveyor belts of different thicknesses.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
