Description

Technical Field

[0001] This utility model relates to the field of electroplating masking fixture technology, and in particular to a novel online masking fixture. Background Technology

[0002] Electroplating of signal terminals typically employs a continuous conveying method, where terminals sequentially pass through an electroplating bath to form a plating layer. To meet the requirement of varying local plating thicknesses, existing processes mainly utilize two methods: flip-over selective plating and in-line shielding fixtures. Flip-over selective plating suspends specific areas in the air using a flipping fixture, resulting in two plating operations with different thicknesses. While this method can precisely control thickness differences, it requires frequent interruptions to the production line for flipping operations, significantly extending plating time and increasing costs. In-line shielding fixtures use a feed trough located below the conveyor belt, utilizing the trough's shielding to reduce localized liquid flow and thin the plating layer in the trough area. This method does not require production interruptions and is lower in cost; however, the currently used feed trough position adjustment mechanism is rudimentary in design and lacks stability, easily swaying as the conveyor belt passes through, making it difficult to accurately position the shielded area. Furthermore, the contact between the bottom of the conveyor belt and the feed trough creates a physical barrier, hindering the flow of solution on both sides of the electroplating bath, resulting in uneven plating thickness on the left and right sides of the conveyor belt and affecting product consistency.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a new type of online masking 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 novel online masking fixture to solve the problems of inaccurate masking positioning and uneven coating thickness in the electroplating process.

[0006] This utility model discloses a novel online shielding fixture, comprising:

[0007] A feed chute with its opening facing upwards, positioned along the X-axis, is used for the passage of the conveyor belt;

[0008] A glass rod is detachably mounted on the feed chute along the Y direction. The top of the outer periphery of the glass rod is higher than the plane where the bottom of the feed chute is located, in order to reduce motion resistance and lift the material belt to form a suspension channel.

[0009] The tie rods located at the front and rear ends of the feed chute are used to stabilize the feed chute and support height adjustment.

[0010] Positioning adjustment components are located at the top of each tie rod;

[0011] The positioning adjustment assembly includes a horizontal support, a slider, a turntable, a first fastening bolt, and a second fastening bolt; the horizontal support has a first guide groove and a first positioning hole along the Y direction; the slider has a second positioning hole and a second guide groove along the Y direction, and a locking hole is provided through the side wall of the second positioning hole; the turntable has an adjustment hole at its center.

[0012] The upper end of the pull rod passes through the first guide groove and the second positioning hole in sequence and is then threadedly connected to the adjustment hole; the first fastening bolt is threadedly connected to the locking hole, and its front end can extend into the second positioning hole to press against the pull rod; the second fastening bolt passes through the second guide groove and is threadedly connected to the first positioning hole.

[0013] Preferred technical solution: The material of the feed trough is fiberglass.

[0014] Preferred technical solution: The tie rod is a titanium alloy lead screw component.

[0015] Preferred technical solution: The front and rear ends of the material conveying chute are provided with flared openings.

[0016] Preferred technical solution: The tilt angle of the flared mouth is 30° to 60°.

[0017] Preferred technical solution: Both ends of the horizontal support are provided with slots for overlapping the side walls of the electroplating tank.

[0018] Preferred technical solution: The outer circumference of the turntable is provided with anti-slip texture.

[0019] Preferred technical solution: There are two sets of glass rods, which are respectively located at the front and rear ends of the feed trough.

[0020] Preferred technical solution: The horizontal support is made of PVC material.

[0021] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0022] This invention reduces contact friction by minimizing the contact area between the glass rod and the conveyor belt, thereby reducing the force exerted by the conveyor belt on the shielding fixture. A basic support platform is formed by a horizontal bracket rigidly overlapping with the side wall of the electroplating tank. The pull rod is staggered and limited by the horizontal bracket and the slider. The upper end of the pull rod passes through the first guide groove and the second positioning hole in sequence before being threaded into the adjustment hole. The first guide groove controls the pull rod to move only in the Y direction, while the second positioning hole restricts the swing of the pull rod. This, combined with a turntable, achieves high-precision lifting and lowering control of the pull rod. The adjusted pull rod is locked in place by a first fastening bolt and a locking hole. A second fastening bolt with a second guide groove is threaded into the first positioning hole. The threaded first positioning hole restricts the swing of the second fastening bolt and locks the slider onto the horizontal bracket, improving slider stability. During adjustment, the second guide groove restricts the movement direction of the second fastening bolt, thus restricting the movement direction of the slider, ultimately forming a dual guide for the pull rod displacement, ensuring the accuracy and stability of the adjustment displacement. The glass rod lifts the material strip to form a suspended material passage, which promotes bidirectional flow of electroplating solution, eliminates solution stagnation on both sides of the material strip, and ensures the uniformity of the plating thickness on both sides of the material strip in the material passage tank.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a novel online shielding fixture, comprising:

[0036] A feed chute 1, which is set along the X direction and has an upward opening, is used for the material belt to pass through and for partial online shielding of it;

[0037] A glass rod 2 is detachably mounted on the feed trough 1 along the Y direction. The top of the outer periphery of the glass rod 2 is higher than the plane where the bottom of the feed trough 1 is located. It is used to lift the feed belt to form a suspended channel and reduce the force of the feed belt movement on the fixture.

[0038] The tie rods 3, located at the front and rear ends of the feed chute 1, are used to support height adjustment and ensure the stability of the feed chute 1.

[0039] Positioning adjustment assembly 4 is located at the top of each tie rod 3;

[0040] The positioning adjustment assembly 4 includes a horizontal support 41, a slider 42, a turntable 43, a first fastening bolt 44, and a second fastening bolt 45. The horizontal support 41 has a first guide groove 411 and a first positioning hole 412 along the Y direction. The slider 42 has a second positioning hole 421 and a second guide groove 422 along the Y direction. The side wall of the second positioning hole 421 has a locking hole 423. The turntable 43 has an adjustment hole 431 at its center.

[0041] The upper end of the pull rod 3 passes through the first guide groove 411 and the second positioning hole 421 in sequence and is threaded to the adjustment hole 431; the first fastening bolt 44 is threaded to the locking hole 423, and its front end can extend into the second positioning hole 421 to press against the pull rod 3; the second fastening bolt 45 passes through the second guide groove 422 and is threaded to the first positioning hole 412.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the material of the feed trough 1 is fiberglass, which increases corrosion resistance and insulation.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, tie rod 3 is a titanium alloy screw component, which has high strength and increases resistance to electrolyte corrosion.

[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the feed chute 1 has flared openings 11 at both ends, with an inclination angle of 30° to guide the feed strip through smoothly. It should be noted that in other embodiments, the inclination angle can be other angles, depending on the thickness of the signal terminals on the feed strip.

[0045] In some embodiments, such as Figure 1 , Figure 2and Figure 3 As shown, both ends of the horizontal support 41 are provided with slots 413 for overlapping the side wall of the electroplating tank, which are used to rigidly overlap the side wall of the electroplating tank and improve the stability of the fixture positioning.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the outer circumference of turntable 43 is provided with anti-slip texture to facilitate manual fine-tuning.

[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, there are two sets of glass rods 2, which are respectively set at the front and rear ends of the feed trough 1 to ensure that the bottom of the feed strip is balanced.

[0048] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the horizontal support 41 is made of PVC, which is lightweight, has strong resistance to deformation, and is resistant to chemical corrosion.

[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in use, the slots 413 at both ends of the horizontal support 41 are attached to the side wall of the electroplating tank to form a rigid support. Rotating the turntable 43 drives the pull rod 3 to rise and fall along the first guide groove 411, moving the material passage 1 to the target height; tightening the first fastening bolt 44 secures the pull rod 3, locking the height. Pushing the slider 42 causes the second guide groove 422 to slide along the second fastening bolt 45, adjusting the Y-axis position of the material passage 1; tightening the second fastening bolt 45 fixes the slider 42. The material strip is introduced through the flared opening 11, and the material passage 1 shields and reduces local liquid flow, thinning the coating of the material strip within the material passage 1 to meet the requirements for varying local coating thickness; simultaneously, the glass rod 2 lifts and forms a suspension channel, allowing the electroplating solution to flow on both sides of the material strip, ensuring consistent coating thickness on both sides of the material strip within the material passage 1. It should be noted that coating variation refers to the difference in coating thickness between the material strip areas inside and outside the material passage.

[0050] This utility model discloses a novel online masking fixture. By combining a suspended material passage design with a dual guiding and positioning mechanism, it solves the problem of uneven coating thickness while ensuring masking accuracy and stability, thus significantly improving production efficiency and product consistency.

[0051] 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.
