Description

Technical Field

[0001] This utility model relates to the field of rack plating technology, and in particular to a rack plating hook and a feeding claw. Background Technology

[0002] Rack plating, also known as "hanging plating," is the most common electroplating method. Specifically, it involves using racks on the production line to suspend the workpiece in an electroplating tank for plating. During rack plating, the rack needs to stably suspend the workpiece and ensure reliable contact, guaranteeing a uniform current flow. Existing racks commonly have a hook shape, with the hook passing through a feature hole on the workpiece to suspend it. The problem with this structure is that the workpiece lacks a restraint mechanism on the rack, causing it to easily wobble during plating, leading to accidental drops, poor conductivity, and reduced plating quality. However, adding a restraint mechanism would increase the structural complexity of the rack, making it difficult to integrate with some unloading mechanisms for automated workpiece unloading. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide a plating hook and a feeding claw, which can stably and conveniently hang workpieces, and the feeding claw can be adapted to the plating hook to realize automatic workpiece feeding.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A plating hook includes a main body that is cylindrical. The head end of the main body is provided with a through hole for inserting into a feature hole of a workpiece. The size of the through hole is smaller than the size of the main body, and the through hole and the main body are connected by a tapered section. The diameter of the feature hole is larger than the small end diameter of the tapered section but smaller than the large end diameter of the tapered section.

[0006] As an alternative, the connection between the conical part and the perforated part is the smallest position on the plating hook, and the end of the perforated part near the conical part is provided with a conical section with the same taper as the conical part.

[0007] As an alternative, the perforated part is provided with several large-diameter sections and small-diameter sections arranged alternately along its own axis. Adjacent large-diameter sections and small-diameter sections are connected by inclined surfaces to form a concave-convex shape for increasing friction.

[0008] As an optional solution, two plating hooks are provided, each of which passes through a feature hole, and the distance between the two plating hooks remains unchanged. When the workpiece mounted on the two plating hooks tilts, the projection distance between the two feature holes on the axis of the plating hooks decreases, so that the workpiece is clamped by the two plating hooks.

[0009] On the other hand, the present invention adopts the following technical solution:

[0010] A feeding claw is used to adapt to the above-mentioned rack plating hook to realize automatic feeding of workpieces hung on the rack plating hook. The feeding claw includes two symmetrically arranged and adjustable clamping claw parts. The first clamping claw part is provided with a positioning vertical plane. The positioning vertical plane is provided with a cavity for avoiding the through hole of the rack plating hook. The positioning vertical plane is used to abut one side of the workpiece and press the workpiece against the conical surface of the rack plating hook so that the workpiece is kept in an upright state. The second clamping claw part is used to cooperate with the first clamping claw part to clamp the workpiece in the upright state.

[0011] As an alternative, the first gripper is provided with a claw hook extending from the positioning vertical plane. The claw hook extends from one side of the workpiece, around the end face of the workpiece, and to the other side of the workpiece. The claw hook is provided with a groove for avoiding the main body of the plating hook.

[0012] As an alternative, a vision camera is provided on the first gripper section. The vision camera is used to identify the position of the plating hook and the workpiece, and to correct the position of the first gripper section.

[0013] The beneficial effects of this utility model are:

[0014] This rack plating hook adopts a straight hook design, which enables the hanging of workpieces and has the advantage of being easy to insert into or remove from the feature holes of the workpieces. In conjunction with a dedicated unloading claw, it can accurately clamp the workpiece after leveling it, realizing automatic unloading of the workpieces and greatly improving rack plating efficiency.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0022] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0026] Please see Figure 1 As shown, this embodiment provides a plating hook 1, including a main body 11, which is cylindrical. The head end of the main body 11 is provided with a through hole 12. The through hole 12 is used to pass through the feature hole 21 of the workpiece 2. The size of the through hole 12 is smaller than the size of the main body 11, and the through hole 12 is connected to the main body 11 through a conical part 13. The diameter of the feature hole 21 is larger than the small end diameter of the conical part 13 but smaller than the large end diameter of the conical part 13.

[0027] Therefore, by shaping the perforated part 12 and the conical part 13 on the plating hook 1, the workpiece 2 can be stably hung on the plating hook 1. Moreover, the straight hook type of the plating hook 1 has the advantage of being easy to insert or withdraw from the feature hole 21 of the workpiece 2 compared with the bent hook structure, which is more conducive to realizing automated material unloading.

[0028] Optionally, the connection between the conical part 13 and the perforated part 12 is the smallest position on the plating hook 1, and a conical section 121 with the same taper as the conical part 13 is provided at one end of the perforated part 12 near the conical part 13.

[0029] Given the above structure, the minimum position of this dimension is the position where the feature hole 21 of the workpiece 2 is suspended under normal conditions (workpiece 2 is in an upright state), so as to limit the axial movement of the workpiece 2 along the plating hook 1 as much as possible.

[0030] Furthermore, the perforated portion 12 is provided with a number of large-diameter sections 122 and small-diameter sections 123 arranged alternately along its own axis. Adjacent large-diameter sections 122 and small-diameter sections 123 are connected by inclined surfaces to form a concave-convex shape for increasing friction.

[0031] Therefore, the concave-convex surface increases the contact area and surface roughness between the perforated portion 12 and the workpiece 2, making it less likely for the workpiece 2 to slide on the perforated portion 12; in addition, the inclined surface connection, compared with the curved surface transition connection, makes the surface of the perforated portion 12 have relatively large friction and will not damage the surface of the workpiece 2.

[0032] To suppress the workpiece 2 from swaying on the straight hook type plating hook 1, two plating hooks 1 are used in combination. Each plating hook 1 passes through a corresponding feature hole 21, and the distance between the two plating hooks 1 remains unchanged. When the workpiece 2 hanging on the two plating hooks 1 tilts, the projection distance of the corresponding two feature holes 21 in the axial direction of the plating hook 1 decreases, so that the workpiece 2 is clamped by the two plating hooks 1.

[0033] The ingenious use of the two plating hooks 1 is that when the workpiece 2 is tilted, one feature hole 21 will move along the conical part 13. As the size of the conical part 13 increases, the movement of the feature hole 21 will be restricted. The other feature hole 21 will enter the concave and convex surface of the perforated part 12 along the conical section 121, thereby enabling the workpiece 2 to reach a balanced position and maintain a stable position.

[0034] Therefore, based on the principle that the vertical distance between the two feature holes 21 decreases when the workpiece 2 is tilted, the workpiece 2 will be clamped when it is tilted, which further ensures the stability of the workpiece 2 and reduces the possibility of the workpiece 2 shaking and falling during the production process.

[0035] Based on this, this embodiment provides a feeding claw 3, which is adapted to the above-mentioned plating hook 1 to realize automatic feeding of the workpiece 2 hanging on the plating hook 1.

[0036] like Figure 2 As shown, the unloading claw 3 includes two symmetrically arranged and adjustable-spaced gripper portions 31. The first gripper portion 31 is provided with a positioning vertical plane 32. The positioning vertical plane 32 is provided with a cavity 33 for avoiding the through hole portion 12 of the plating hook 1. The positioning vertical plane 32 is used to abut against one side of the workpiece 2 and press the workpiece 2 against the conical surface portion 13 of the plating hook 1, so that the workpiece 2 remains upright. The second gripper portion 31 is used to cooperate with the first gripper portion 31 to clamp the workpiece 2 in the upright state.

[0037] Thus, by having the first gripper 31 press against the workpiece 2, the workpiece 2 can be positioned along the plating hook 1 to ensure it is in an upright state, thus achieving a regularizing effect; then, the second gripper 31 moves closer to the first gripper 31 to accurately clamp the workpiece 2.

[0038] The first gripper 31 is used to primarily position and stabilize the workpiece 2 on the plating hook 1, while the second gripper 31 serves as an auxiliary clamping function. The structure of the second gripper 31 can be the same as that of the first gripper 31, or it can be simplified to meet the clamping requirements.

[0039] The two gripper parts 31 here can be installed on existing robotic arms to meet the transfer requirements; in addition, the structure required to realize the relative movement of the two gripper parts 31 to complete the clamping or releasing action is existing technology and will not be described in detail here.

[0040] Optionally, the first gripper portion 31 is provided with a claw hook portion 34 extending from the positioning vertical plane 32. The claw hook portion 34 passes around the end face of the workpiece 2 from one side and extends to the other side of the workpiece 2. The claw hook portion 34 is provided with a groove 35 for avoiding the main body portion 11 of the plating hook 1.

[0041] Thus, the claw hook 34 achieves the function of limiting the workpiece 2, and the groove 35 on the claw hook 34 and the cavity 33 on the positioning vertical plane 32 are used to avoid the plating hook 1 on the one hand, and to calibrate the position of the plating hook 1 and the workpiece 2 on the other hand, so as to ensure that the workpiece 2 can be accurately clamped.

[0042] Optionally, a vision camera is provided on the first gripper 31. The vision camera is used to identify the position of the plating hook 1 and the workpiece 2, and to correct the position of the first gripper 31.

[0043] Among them, the first gripper 31 is the main component for determining the position of the plating hook 1 and the workpiece 2 as the unloading claw 3. It is necessary to ensure its positional accuracy. Visual recognition through a vision camera can improve its positional accuracy so that it can cooperate with the second gripper 31 to perform the clamping action.

[0044] Detailed material cutting process:

[0045] 1) The first gripper part 31 and the second gripper part 31 of the unloading claw 3 open and move close to the workpiece 2 as a whole;

[0046] 2) The positioning vertical plane 32 of the first gripper 31 is attached to the workpiece 2, and as the first gripper 31 is fed, it gradually flattens the workpiece 2.

[0047] 3) The vision camera on the first gripper 31 takes pictures and uploads them to the system. The system program provides feedback to adjust and correct the relative position of the unloading gripper 3 and the workpiece 2.

[0048] 4) The second gripper 31 moves and cooperates with the first gripper 31 to clamp the workpiece 2 in the vertical position, thus completing the unloading.

[0049] It should be noted that during the leveling process, if the center of gravity of workpiece 2 shifts, the leveling process will adjust the center of gravity of workpiece 2 and automatically straighten workpiece 2 into an upright position for subsequent clamping actions.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
