Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electroplating equipment, in particular to a thin film electroplating conductive clip with a long groove positioning. Background Art
[0002] In the electroplating industry, horizontal electroplating process and vertical electroplating process are two common and important electroplating methods. The horizontal electroplating process has occupied a place in the electroplating field with its unique operation mode. In order to achieve the automation and efficiency of the electroplating process, the drive devices are cleverly used in the horizontal electroplating process. These drives evenly clamp the edges of the film through well-designed clamps. These clamps not only ensure the stability of the film during the electroplating process, but also enable the film to run smoothly along the tank body in the electroplating tank. In this way, the film can complete the entire electroplating process in the electroplating tank, achieving uniformity and consistency of electroplating.
[0003] The horizontal electroplating process has a wide range of application prospects in the electroplating industry. Through its unique layout design and the application of the drive device, the horizontal electroplating process can realize the automation, efficiency and stabilization of the electroplating process. At the same time, the process also has the advantages of good electroplating uniformity and high production efficiency. It is one of the indispensable and important processes in the electroplating industry.
[0004] In the prior art, the lower clamp in the clamp is fixed on the steel belt. The lower film surface to be plated fits with the upper end surface of the lower clamp, and then the upper clamp moves downward until the lower end surface of the upper clamp fits with the upper end surface of the film to be plated. In this way, the clamping of the film to be plated is completed. Generally, a guide wheel is set on the upper clamp, which cooperates with the guide rail to make the upper clamp move up and down, so that the clamp is opened and closed. The existing clamp is repeatedly opened and closed, and it is easy for the lower end surface of the upper clamp to be misaligned with the upper end surface of the lower clamp when closing, which makes the film to be plated easy to be torn, affecting the quality of electroplating.
[0005] The above problems need to be solved urgently. Utility Model Content
[0006] In order to overcome the disadvantage of the prior art that the clamping surfaces of the conductive upper clamp and the conductive lower clamp are easily misaligned when clamped together, the utility model provides a thin film electroplating conductive clamp with a long groove for positioning.
[0007] The technical solution of the utility model is as follows:
[0008] A thin film electroplating conductive clamp with long groove positioning, comprising a conductive upper clamp and a conductive lower clamp, the conductive lower clamp being provided with a positioning boss, the positioning boss being provided with a slide groove, the slide groove being provided with a second positioning pin shaft, and the side walls on both sides of the slide groove being provided with a first positioning long groove; the conductive upper clamp being provided with a second positioning long groove, and the two sides of the conductive upper clamp being provided with a first positioning pin shaft respectively, when the conductive upper clamp is embedded in the slide groove, the second positioning pin shaft is inserted into the second positioning long groove and the first positioning pin shaft at the corresponding position on the same side is inserted into the first positioning long groove, and the conductive upper clamp can slide up and down along the slide groove to open and close the clamp mouth.
[0009] Furthermore, in one embodiment, a groove is provided in the middle of the slide groove along the length direction of the slide groove, and the second positioning pin is fixed in the groove.
[0010] Further, in one embodiment, the first positioning pin shaft is arranged corresponding to the positioning boss, and there are multiple positioning bosses.
[0011] Furthermore, in one embodiment, the upper end of the first positioning slot is open.
[0012] Further, in one embodiment, the length of the second positioning long groove is greater than the length of the first positioning long groove.
[0013] Furthermore, in one embodiment, the conductive upper clamp and the conductive lower clamp are both provided with a sheath on the outer side of the clamping end, and the sheath is made of insulating material.
[0014] Furthermore, in one embodiment, the upper ends of the conductive lower clip and the conductive upper clip are both provided with binding posts, and the binding posts are used to connect wires.
[0015] Furthermore, in one embodiment, the contact surfaces of the clamping openings of the conductive upper clamp and the conductive lower clamp are upward convex arc surfaces.
[0016] The utility model according to the above scheme has the beneficial effect that, on the conductive clip, under the cooperation of the first positioning long groove and the first positioning pin, and the cooperation of the second positioning long groove and the second positioning pin shaft, the conductive upper clip can slide up and down in the slide groove to complete the opening and closing of the conductive clip, and the positioning is performed by the linear contact between the positioning pin shaft and the long groove, so that the conductive upper clip can be effectively positioned in the slide groove of the conductive lower clip in all directions, front, back, left and right, to ensure the precise alignment of the conductive upper clip and the conductive lower clip. The present application has a simple structure and accurate positioning. At the same time, since the positioning components all adopt line-surface contact, the contact area between the conductive upper clip and the conductive lower clip is effectively reduced, that is, the friction resistance between the conductive upper clip and the conductive lower clip is significantly reduced, which facilitates the smooth opening and closing of the conductive clip and prevents jamming.

[0024] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0025] like Figure 1 and Figure 2 As shown, the present application provides a thin film electroplating conductive clip with long groove positioning, and the thin film electroplating conductive clip with long groove positioning includes a conductive upper clip 200 and a conductive lower clip 100, the conductive lower clip 100 is provided with a positioning boss 110, the positioning boss 110 is provided with a slide groove 1101, the slide groove 1101 is provided with a second positioning pin shaft 1103, and the side walls of the slide groove 1101 are provided with a first positioning long groove 1102; the conductive upper clip 200 is provided with a second positioning long groove 210, and the two sides of the conductive upper clip 200 are respectively provided with a first positioning pin shaft 220, when the conductive upper clip 200 is embedded in the slide groove 1101, the second positioning pin shaft 1103 is inserted into the second positioning long groove 210 and the first positioning pin shaft 220 at the corresponding position on the same side is inserted into the first positioning long groove 1102, and the conductive upper clip 200 can slide up and down along the slide groove 1101 to open and close the clamp. On the conductive clip, under the cooperation of the first positioning long groove 1102 and the first positioning pin, and the cooperation of the second positioning long groove 210 and the second positioning pin shaft 1103, the conductive upper clip 200 can slide up and down in the slide groove 1101 to complete the opening and closing of the conductive clip, and the positioning is performed by the linear contact between the positioning pin shaft and the long groove, so that the conductive upper clip 200 can be effectively positioned in the slide groove 1101 of the conductive lower clip 100 in all directions, front, back, left and right, to ensure the precise alignment of the conductive upper clip 200 and the conductive lower clip 100. The present application has a simple structure and accurate positioning.
[0026] At the same time, since the positioning components are all in line-surface contact, the contact area between the conductive upper clip 200 and the conductive lower clip 100 is effectively reduced. Since the size of the friction force between the two objects sliding relative to each other is proportional to the size of the contact area, the positioning structure design of the present application significantly reduces the friction resistance between the conductive upper clip 200 and the conductive lower clip 100, which is convenient for the conductive clip to open and close smoothly and prevent jamming. When the acid mist crystals of the electroplating solution are condensed on the conductive upper clip 200 and the conductive lower clip 100, when the conductive upper clip 200 slides, the smaller contact area can also reduce the obstruction of the acid mist crystals to the first positioning pin 220 and the second positioning pin 1103, and facilitate the cleaning of the acid mist crystals, which is beneficial to the extension of the service life of the conductive clip.
[0027] like Figure 3 and Figure 4 As shown, in a preferred embodiment, a groove 1104 is provided in the middle of the slide groove 1101 along the length direction of the slide groove 1101, and the second positioning pin 1103 is fixed in the groove 1104. The groove 1104 is recessed toward the rear side of the slide groove 1101, so that the center of the slide groove 1101 does not contact the conductive upper clip 200, reducing the contact area between the positioning boss 110 and the conductive upper clip 200, further reducing the friction resistance between the conductive upper clip 200 and the conductive lower clip 100, and facilitating the opening and closing of the conductive clip.
[0028] like Figure 1 As shown, in a preferred embodiment, the positioning boss 110 and the first positioning pin 220 are correspondingly arranged, and there are multiple positioning bosses 110. In this embodiment, there are two positioning bosses 110, so that the conductive upper clip 200 can slide up and down on the conductive lower clip 100 more stably, and it is not easy to cause forward and backward displacement.
[0029] like Figure 2 As shown, in a preferred embodiment, the upper end of the first positioning slot 1102 is open. The open first positioning slot 1102 not only maintains the guiding function, but also facilitates the disassembly between the conductive upper clip 200 and the conductive lower clip 100, simplifies the installation and disassembly process of the conductive clip, reduces the difficulty of maintenance work, and greatly reduces the maintenance time of the conductive clip. In other embodiments, the first positioning slot 1102 can also be designed to be non-open.
[0030] In a preferred embodiment, the length of the second positioning slot 210 is greater than the length of the first positioning slot 1102. With a longer second positioning slot 210, when the second positioning pin 1103 moves to the end point of the second positioning slot 210, the first positioning pin 220 moves out of the first positioning slot 1102, making it easier to disassemble and remove the conductive upper clip 200.
[0031] In a preferred embodiment, the conductive upper clip 200 and the conductive lower clip 100 are both provided with a sheath on the outside of the clamping end, and the sheath is made of insulating material. The sheath is made of insulating material. The conductive upper clip 200 and the conductive lower clip 100 are exposed only at the part in contact with the film to ensure good conductivity. By providing the insulating material sheath, the exposed part is reduced, the deposition of the coating on the conductive clip is reduced, the cleaning frequency is reduced, and the material waste is reduced.
[0032] In a preferred embodiment, the upper ends of the conductive lower clip 100 and the conductive upper clip 200 are both provided with terminals, and the terminals are used to connect the wires. The conductive lower clip 100 is connected to the cathode of the power supply, and the conductive upper clip 200 is electrically connected to the conductive lower clip 100 through the wire, so that the conductive upper clip 200 and the cathode of the power supply maintain a stable electrical connection, so that the upper and lower surfaces of the film can be well connected to the cathode of the power supply, thereby ensuring a good electroplating effect.
[0033] In a preferred embodiment, the contact surface of the clamping opening of the conductive upper clamp 200 and the conductive lower clamp 100 is an upward convex arc surface. The clamping contact surface of the conductive lower clamp 100 and the conductive upper clamp 200 is an arc surface that fits each other. When the two arc surfaces are in contact, they can be automatically aligned, so that the film can be better clamped.
[0034] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
[0035] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
