Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to a conductive clip and an electroplating film coating device. Background Art

[0002] Electroplating refers to the process of depositing metal on the surface of a conductive material in an electroplating solution. In an electroplating device, the conductive film to be electroplated needs to be placed in an electroplating tank and electroplated with the electroplating solution. In this process, a rolled conductive film will be released from the unwinding end. After entering the electroplating tank, the conductive film will also rotate with the steel belt driven by the steel roller to achieve full contact with the electroplating solution. After the electroplating is completed, the finished conductive film will be rolled up by the winding end. During the electroplating process, the conductive film needs to rotate synchronously with the steel belt. For this purpose, a conductive clamp needs to be set on the steel belt to fix the conductive film.

[0003] In the process of implementing the present utility model, the inventors found that there are at least the following problems in the prior art:

[0004] When the existing conductive clamps clamp the conductive film, the conductive film is often damaged, which affects the qualified rate of the finished product. Therefore, how to improve the conductive film clamping device to avoid the conductive film from being damaged during the clamping process is a problem that needs to be solved. Utility Model Content

[0005] The embodiments of the utility model provide a conductive clamp and an electroplating film coating device, which are used to solve the problem in the prior art that the conductive film is easily damaged during the clamping process.

[0006] To achieve the above-mentioned purpose, an embodiment of the utility model provides a conductive clamp, comprising a first clamping body, a second clamping body, and a limiting guide structure; the first clamping body is an L-shaped structure composed of a vertical first side block and a horizontal first bottom block, and the second clamping body is an L-shaped structure composed of a vertical second side block and a horizontal second bottom block; the first clamping body and the second clamping body have the same orientation, the first clamping body is located inside the second clamping body, and a predetermined gap is left between the first side block and the second side block; the first clamping body can move up and down along the limiting guide structure; the limiting guide structure makes it possible for the gap between the bottom surface of the first bottom block and the top surface of the second bottom block to be smaller than the thickness of the conductive film to be electroplated when the first clamping body is in the lowest position; the first bottom block and the second bottom block are both covered with a protective layer.

[0007] In addition, an embodiment of the utility model also provides an electroplating film coating device, including a unwinding end, a winding end, an electroplating tank, two steel rollers driven by a motor vertically arranged in the electroplating tank, and a steel belt rotating around the steel rollers, the outer side surface of the steel belt is connected to the conductive clamp as described above; the two ends of the conductive film to be electroplated are respectively connected to the unwinding end and the winding end, and the part of the conductive film located in the electroplating area is clamped by the conductive clamp.

[0008] The above technical solution has the following beneficial effects:

[0009] In the present technical solution, since the bottom of the first clamping body and the second clamping body are provided with a protective layer made of a material with good elasticity, it can be prevented that the first bottom edge block and the second bottom edge block made of metal material directly contact the thin and fragile guide membrane when clamping the guide membrane, thereby reducing or even eliminating the damage to the guide membrane caused by the clamping operation and improving the yield rate.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , Figure 2 As shown, an embodiment of the utility model provides a conductive clamp, comprising a first clamping body, a second clamping body, and a limiting guide structure; the first clamping body is an L-shaped structure composed of a vertical first side block 2 and a horizontal first bottom block 1, and the second clamping body is an L-shaped structure composed of a vertical second side block 8 and a horizontal second bottom block 10; the first clamping body and the second clamping body have the same orientation, the first clamping body is located inside the second clamping body, and a predetermined gap is left between the first side block 2 and the second side block 8; the first clamping body can move up and down along the limiting guide structure; the limiting guide structure makes it possible for the gap between the bottom surface of the first bottom block 1 and the top surface of the second bottom block 10 to be smaller than the thickness of the conductive film to be electroplated when the first clamping body is in the lowest position; the first bottom block 1 and the second bottom block 10 are both covered with a protective layer.

[0020] In order to solve the above-mentioned problem, a protective layer is provided at the clamping parts of the first clamping body and the second clamping body (i.e., between the bottom surface of the first bottom edge block 1 and the top surface of the second bottom edge block 10), which can prevent the first bottom edge block 1 and the second bottom edge block 10 made of metal from directly contacting the thin and fragile guide film during the clamping operation, thereby reducing or even eliminating the damage to the guide film caused by the clamping operation and improving the yield rate.

[0021] At the same time, the first clamping body and the second clamping body can realize relative movement, that is, the second clamping body is fixed, and the first clamping body can move up and down along the limiting guide structure. When the first clamping body moves up under the action of external force, the first bottom edge block 1 and the second bottom edge block 10 will generate the following Figure 3 As shown in the gap (in order to be able to clamp the conductive film, the gap can be designed to be slightly smaller than the thickness of the conductive film), the conductive film to be electroplated can be extended into the gap at this time, and then the first clamping body is moved downward to the lowest position under the action of external force, so that the gap between the bottom surface of the first bottom edge block 1 and the top surface of the second bottom edge block 10 is minimized and the conductive film is clamped, and the conductive film can be driven by the conductive clamp to move synchronously with the steel strip to the electroplating operation area of ​​the electroplating tank. When the electroplating is completed, the plated conductive film will undergo subsequent process processing, and at this time the first clamping body is moved up again, and a larger gap is generated between the first bottom edge block 1 and the second bottom edge block 10 again, so that the conductive film can be separated from the conductive clamp.

[0022] It should be noted that the protective layer is preferably made of non-metallic materials with good elasticity, such as rubber, polyurethane, etc. At the same time, if only the bottom surface of the first bottom edge block 1 and the top surface of the second bottom edge block 10 are provided with a non-metallic protective layer, the processing is relatively difficult, and the bonding effect between the protective layer and the first bottom edge block 1 and the second bottom edge block 10 made of metal may not be particularly ideal. Figure 1 As shown, the first bottom edge block 1 and the second bottom edge block 10 can be integrally coated so that the protective layer forms a "protective cover". Furthermore, the lower halves of the first side edge block 2 and the second side edge block 8 can be coated with non-metallic materials together with the bottom edge blocks. For example, they can be coated with rubber.

[0023] Furthermore, the top surface of the second bottom edge block 10 is fixedly connected to the second conductive block 17, and the top surface of the second conductive block 17 exposes the top surface of the corresponding protective layer; the bottom surface of the first bottom edge block 1 is fixedly connected to the first conductive block 16, and the bottom surface of the first conductive block 16 exposes the top surface of the corresponding protective layer.

[0024] Since non-metallic materials are usually insulating materials, if the protective layer is completely closed, it will actually form an insulating layer. At this time, the first clamping body and the second clamping body cannot be connected, and the conductive film clamped between the first clamping body and the second clamping body cannot complete the electroplating work. To solve this problem, Figure 4 , Figure 5 As shown, the second conductive block 17 and the first conductive block 16 can be respectively arranged on the top surface of the second bottom edge block 10 and the bottom surface of the first bottom edge block 1, and the two conductive blocks are connected to the first clamping body and the second clamping body made of metal. When working, the second conductive block 17 and the first conductive block 16 are respectively in contact with the conductive film clamped in the middle, so that the first clamping body and the second clamping body. In other words, the protective layer does not completely seal the first bottom edge block 1 and the second bottom edge block 10, but leaves two "gaps" at the positions of the first conductive block 16 and the second conductive block 17.

[0025] Furthermore, the first conductive blocks 16 and the second conductive blocks 17 are alternately arranged in the front-to-back direction.

[0026] like Figure 4 , Figure 5 As shown, the first conductive block 16 is arranged at the first groove 12, and the second conductive block 17 is arranged at the second groove 15. Obviously, the two are not aligned up and down, but staggered front and back. This is to avoid short circuit in accidental situations (when the conductive film is not clamped, the first bottom edge block 1 and the second bottom edge block 10 are in direct contact).

[0027] Furthermore, the limiting guide structure includes a limiting guide groove 3 provided on the first side block 2 , and a limiting guide column 4 connected to the second side block 8 , and the limiting guide column 4 passes through the limiting guide groove 3 .

[0028] The limiting guide structure can be in various forms. The embodiment of the utility model preferably adopts Figure 1 , Figure 2 In the form shown, one end of the limit guide column 4 is installed on the second side block 8 through a thread, and the nut at the other end is exposed on the outside of the limit guide groove 3, and the limit guide groove 3 is set through the first side block 2. When the top of the limit guide column 4 contacts the upper end surface of the limit guide groove 3, the first clamping body reaches the upper limit of the stroke, and when the bottom of the limit guide column 4 contacts the lower end surface of the limit guide groove 3, the first clamping body reaches the lower limit of the stroke. In addition, it can also be applied in reverse, that is, the limit guide groove 3 is set on the second side block 8, and the limit guide column 4 is set on the first side block 2, and the same effect can be achieved.

[0029] Furthermore, the bottom surface of the first bottom edge block 1 is a first curved surface, and the top surface of the second bottom edge block 10 is a second curved surface matching the first curved surface.

[0030] The clamping surfaces of the two existing clamping bodies are both flat, and the conductive film is clamped by a certain pressure. Although this method is simple, the clamping method is not reliable, and the conductive film often falls off accidentally. For this reason, in the present technical solution, the commonly used plane form is changed to a curved surface form, so that the bottom surface of the first bottom edge block 1 and the top surface of the second bottom edge block 10 are both in a staggered shape. These protrusions and depressions can "bite" the conductive film clamped therebetween like teeth. Compared with the traditional planar contact surface, it can provide a more reliable clamping force to prevent the conductive film from falling off accidentally.

[0031] Furthermore, projections of the first curved surface and the second curved surface on the vertical section are both wavy lines.

[0032] Too complex surface structure will increase the difficulty of processing, so it is preferred to use Figure 2 The regular wavy structure shown.

[0033] Furthermore, the first curved surface includes a first groove 12 and a first boss 13 , and the second curved surface includes a second boss 14 and a second groove 15 . The second boss 14 matches the first groove 12 , and the second groove 15 matches the first boss 13 .

[0034] For the specific shapes of the first and second curved surfaces, see Figure 3, are all shapes in which crests and troughs are connected. At the same time, the crests of the second curved surface (i.e., the second boss 14) match the shape and position of the troughs of the first curved surface (i.e., the first groove 12), and the troughs of the second curved surface (i.e., the second groove 15) match the shape and position of the crests of the first curved surface (i.e., the first boss 13), thereby forming a staggered arrangement, so that after the second clamping body falls to the extreme position, a uniform wavy gap is formed between the two curved surfaces, thereby achieving reliable clamping of the conductive film.

[0035] Furthermore, the second side block 8 is also connected to a guide sleeve 7 with a square hollow structure, and the guide sleeve 7 is sleeved on the outside of the first side block 2; the side of the first side block 2 is also provided with a track groove 9, and the guide sleeve 7 is provided with a ball 11 matching the track groove 9.

[0036] In order to achieve a better guiding effect, in addition to the position-limiting guiding structure, a guide sleeve 7 is additionally provided. The guide sleeve 7 is a hollow square frame structure, which is sleeved on the outside of the first side block 2 to prevent the first side block 2 from deflecting when moving up and down. The ball 11 can reduce the friction during movement and prevent jamming. Preferably, the position-limiting guiding structure is provided in two groups up and down, and the guide sleeve 7 is also provided in two groups up and down.

[0037] Furthermore, a pulley is connected to the inner side of the first side block 2, and a pulley is connected to the outer side of the second side block 8, and the axis of the pulley is arranged horizontally.

[0038] The first side block 2 and the second side block 8 are both equipped with a pulley 5 extending outward through a pin shaft 6. The pulley 5 has two functions: 1. During electroplating, the conductive clamp is installed on the side of the steel strip. Due to factors such as vibration, the steel strip often swings, which affects the electroplating effect. A horizontal guide track is set on the side of the steel strip, and the pulley 5 runs along the track groove set on the guide track, which will support the steel strip and effectively prevent the steel strip from swinging. 2. By setting an ascending track at a predetermined position (whose height is higher than the guide track), the pulley 5 can be pushed to a higher position, so that the first clamping body moves upward, thereby generating Figure 3 The gap between the first bottom edge block 1 and the second bottom edge block 10 is shown, and this process can also be called the opening of the conductive clamp; at another predetermined position, a descending track is set to push the pulley 5 to lower its position, so that the first clamping body moves downward, thereby restoring the gap between the first bottom edge block 1 and the second bottom edge block 10 to the clamping state, and this process can also be called the closing of the conductive clamp.

[0039] The embodiment of the utility model also provides an electroplating film coating device, including an unwinding end, a winding end, an electroplating tank, two steel rollers driven by a motor vertically arranged in the electroplating tank, and a steel belt rotating around the steel rollers, the outer side of the steel belt is connected with a conductive clamp as described above; the two ends of the conductive film to be electroplated are respectively connected to the unwinding end and the winding end, and the part of the conductive film located in the electroplating area is clamped by the conductive clamp. The unwinding end and the winding end are necessary for film coating, the unwinding end is used to unwind the conductive film, and the winding end is used to wind it; the electroplating solution is arranged in the electroplating tank, and there is an anode device in the electroplating tank. In this application, the anode device is an insoluble anode, and can also be a titanium basket. A copper ball is arranged in the titanium basket, and the insoluble anode does not need a copper ball, and there are copper ions in the electroplating solution. By adopting the aforementioned conductive clamp, the accidental damage of the conductive film when the electroplating film coating device is used can be reduced, and it can have a better clamping force to ensure the continuous operation of production.
