Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to a conductive clamp with stable clamping and a water electroplating device. Background Art

[0002] Water electroplating is a process that uses the principle of electrolysis to reduce metal ions in the plating solution and make a thin layer of metal or alloy film adhere to the surface of the base film immersed in the plating solution. In the water electroplating device, a conveyor belt is needed to drive the conductive clamp to move, and the conductive clamp clamps the base film in and out of the plating tank. The specific process is as follows: before the conductive clamp enters the plating tank, its initial state is open, so that it can then be switched to a closed state to clamp the conductive base film; driven by the conveyor belt, the conductive clamp enters the plating tank together with the clamped conductive base film and moves in the tank; during this process, the conductive clamp continues to remain in a closed state; after the conductive clamp leaves the plating tank with the conductive base film, the conductive clamp state is switched from closed to open, releasing the conductive base film and completing the clamping task.

[0003] In order to improve the automatic opening and closing of the conductive clip and reduce the inconvenience of manual control, a Chinese invention with publication number CN113247544A discloses a conductive clip transmission and opening and closing device, wherein the conductive clip includes a fixed clamping arm and a movable clamping arm, the fixed clamping arm is movably connected to the movable clamping arm, and a guide portion is provided on the movable clamping arm. The movable clamping arm can move in a vertical direction relative to the fixed clamping arm to put the conductive clip in a clamping state or an open state; the transmission device is used to drive the conductive clip to move along a preset track; the guide rail is arranged along the moving path of the conductive clip, when the guide portion cooperates with the guide rail, the movable clamping arm is lifted by the guide rail to open the conductive clip, and when the guide portion is disengaged from the guide rail, the movable clamping arm falls under the action of gravity to close the conductive clip.

[0004] It can be seen that the closing of the two clamping arms in the above technical solution only relies on the gravity of the movable clamping arm. After closing, the two clamping arms are in a natural state. This places high demands on the assembly structure of the conductive clamp. It should ensure that the upper and lower clamping plates can remain parallel. In addition, due to the large range of up and down movement of the movable clamping arm, there are also high-quality requirements for the connecting parts of the two clamping arms. It should ensure that the movable clamping arm does not deviate or tilt after multiple openings and closings. Otherwise, as long as there is a point that does not meet the standard, it is very easy to cause the upper and lower clamping surfaces of the conductive clamp to be point contact or line contact when clamping the film, rather than good surface contact, resulting in poor clamping.

[0005] The above problems are worth solving. Utility Model Content

[0016] A second spring is also arranged in the shell, and the second spring is sleeved on the first vertical rod. One end of the second spring abuts against the top of the shell, and the other end abuts against the abutting block.

[0017] Furthermore, the top end of the first vertical rod is connected to the roller via a cross rod, and a strip hole is provided in the shell corresponding to the cross rod; the bottom end of the second vertical rod passes through the shell and is connected to the connecting rod assembly.

[0018] The utility model also provides a water electroplating device, including a conveyor belt, a guide rail and an electroplating tank, and a stably clamped conductive clamp including the above-mentioned scheme, wherein the conveyor belt is used to drive the conductive clamp to move along the guide rail, the guide rail includes a high track section and a low track section, and the high track section is arranged corresponding to the electroplating tank, so that when the conductive clamp moves to directly above the electroplating tank, the roller of the conductive clamp is located on the high track section.

[0039] Embodiment 1

[0040] like Figures 1 to 4 As shown, a water electroplating device includes a conveyor belt 3, a guide rail 2, an electroplating tank and a conductive clamp 1. The conveyor belt 3 is a circulating steel belt. The guide rail 2 is arranged along the outer periphery of the conveyor belt 3, and the guide rail 2 is an oblong guide rail. The conductive clamp 1 is fixed on the conveyor belt 3, so that the conveyor belt 3 drives the conductive clamp 1 to move along the guide rail 2. The conductive clamp 1 includes a fixed clamping arm 11 and a movable clamping arm 12, and the fixed clamping arm 11 is fixedly connected to the conveyor belt 3. Specifically, the top of the fixed clamping arm 11 is fixedly connected to the outer side of the conveyor belt 3, and the movable clamping arm 12 is located on the inner side of the conveyor belt 3. Sufficient space should be left from the bottom of the inner conveyor belt 3 wheel to the bottom edge of the conveyor belt 3 to avoid interference with the movable clamping arm 12.

[0041] The guide rail 2 includes a high rail section 21 and a low rail section 22. A transition slope is provided at the junction of the high rail section 21 and the low rail section 22. The high rail section 21 is arranged corresponding to the electroplating tank, that is, the electroplating tank is located below the high rail section 21. When the roller 122 of the conductive clamp 1 moves to the high rail section 21, the conductive clamp 1 clamps the base film and enters the electroplating tank.

[0042] In this embodiment, the fixed clamping arm 11 is provided with at least two horizontal sleeve rods 112, and the movable clamping arm 12 vertically passes through the ends of the horizontal sleeve rods 112, and the movable clamping arm 12 can move up and down, so that the movable clamping arm 12 can move in the vertical direction relative to the fixed clamping arm 11. A roller 122 is provided on the top of the movable clamping arm 12, and the roller 122 moves on the guide rail 2. When the roller 122 moves to the high track section 21, the roller 122 is located at a higher position, so that the movable clamping arm 12 is raised; when the roller 122 moves to the low track section 22, the roller 122 is located at a lower position, so that the movable clamping arm 12 falls.

[0043] A horizontally fixed lower clamping plate 111 is provided at the bottom of the fixed clamping arm 11, and an upper clamping plate 121 is provided at the bottom of the movable clamping arm 12. The upper clamping plate 121 is hinged with the lower clamping plate 111 at one end close to the conveyor belt 3, and a clamping opening is formed at the other end. The opening is opened and closed by rotating the upper clamping plate 121 around the hinge point. A connecting rod assembly is also provided at the bottom of the movable clamping arm 12, and the movable clamping arm 12 drives the upper clamping plate 121 to rotate around the end connection point through the connecting rod assembly.

[0044] When the movable clamping arm 12 moves upward, the upper clamping plate 121 moves around the hinge point of the two clamping plates. Figure 1 When the movable clamping arm 12 moves downward, the upper clamping plate 121 rotates counterclockwise to close the clamping mouth; when ... Figure 1Thus, the closing of the jaws of the conductive clamp 1 is achieved by the rotation of the upper clamping plate 121 around the end portion, the upper clamping plate 121 does not need to move up and down significantly, and there is no gap error in the installation process at the hinge point of the end portion, the requirements for the assembly structure are reduced, and when the upper and lower clamping surfaces are always kept in a clamping state, they must be in surface contact, thereby ensuring that the conductive clamp 1 can stably clamp the base film.

[0045] On the other hand, the closing of the conductive clamp is achieved through the stable cooperation between the roller and the guide rail. The movable clamping arm is subjected to external force. Only when the conductive clamp is opened, the movable clamping arm is in a natural state without force. In contrast, there is no need to worry about the movable clamping arm not falling into place or unstable clamping force due to jamming or assembly problems.

[0046] In this embodiment, the connecting rod assembly includes a first connecting rod 131, a second connecting rod 132 and a third connecting rod 133. The first connecting rod 131 is vertically fixed to the bottom of the movable clamping arm 12. The end of the first connecting rod 131 is hinged to one end of the second connecting rod 132. The other end of the second connecting rod 132 is hinged to the third connecting rod 133. The other end of the third connecting rod 133 is fixedly connected to the end of the upper clamping plate 121 and is hinged to the end of the lower clamping plate 111. When the movable clamping arm 12 is lifted, the first connecting rod 131 moves upward to pull the end of the second connecting rod 132. The other end of the second connecting rod 132 pulls the end of the third connecting rod 133 upward, so that the third connecting rod 133 rotates around the hinge position and the other end of the third connecting rod 133 moves upward. Figure 1 The upper clamping plate 121 rotates counterclockwise along with the third connecting rod 133 to complete the closing.

[0047] Embodiment 2

[0048] A water electroplating device comprises a conveyor belt 3, a guide rail 2, an electroplating tank and a conductive clamp 1. The basic structure is the same as that of the first embodiment, except that the structure of the movable clamping arm is different.

[0049] In this embodiment, the movable clamping arm 12 includes a shell, a first vertical rod 124 and a second vertical rod 125. The shell is hollow inside. The first vertical rod 124 and the second vertical rod 125 are movably arranged in the shell cavity, and an abutment block 126 is arranged between the first vertical rod 124 and the second vertical rod 125. A first spring 127 is also arranged in the shell. The first spring 127 is sleeved on the second vertical rod 125, and one end of the first spring 127 abuts the bottom of the shell, and the other end abuts the lower surface of the abutment block 126. A cross bar 123 is arranged at the top end of the first vertical rod 124. The cross bar 123 passes through the shell and is connected to the roller 122. The end of the cross bar 123 is rotatably connected to the roller 122. Correspondingly, the shell is provided with a bar hole (not shown in the figure), and the cross bar 123 can move up and down along the bar hole.

[0050] When the roller 122 enters the high track section 21, the roller 122 drives the first vertical rod 124 to move upward through the cross bar 123, and the second vertical rod 125 moves upward following the abutment block 126 at its top, at which time the elastic force of the first spring 127 on the lower surface of the abutment block 126 is released. Since the bottom of the second vertical rod 125 is connected to the first connecting rod 131, the upper clamping plate 121 is driven to rotate by the connecting rod assembly to complete the clamping mouth closure, and the conductive clamp 1 is in a clamped state. The structure of the connecting rod assembly is the same as that of the first embodiment, and the movement process is not repeated here.

[0051] When the roller 122 enters the low track section 22, the cross bar 123, the first vertical bar 124, the abutment block 126 and the second vertical bar 125 descend under the action of gravity, and the first spring 127 is compressed. Figure 2 In this embodiment, the sum of the gravity of the cross bar 123, the first vertical bar 124, the abutment block 126 and the second vertical bar 125 is greater than the elastic force of the first spring 127. The function of the first spring 127 is to assist the roller 122 to smoothly enter the high track section 21, so that the clamping jaws can be closed more quickly.

[0052] Embodiment 3

[0053] A water electroplating device includes a conveyor belt 3, a guide rail 2, an electroplating tank and a conductive clamp 1. The basic structure is the same as that of the second embodiment, except that the spring is arranged differently in the shell cavity of the movable clamping arm 12. Instead of the first spring 127, a second spring is arranged in the shell. Specifically, the second spring is sleeved on the first vertical rod 124, and one end of the second spring abuts against the top of the shell, and the other end abuts against the upper surface of the abutment block 126.

[0054] When the roller 122 enters the high track section 21, the roller 122 drives the first vertical rod 124, the abutment block 126 and the second vertical rod 125 to move upward through the cross bar 123, and the abutment block 126 compresses the second spring. The second vertical rod 125 drives the upper clamping plate 121 to rotate through the connecting rod assembly to complete the clamping mouth closure, and the conductive clamp 1 is in a clamping state. The structure of the connecting rod assembly is the same as that of the first embodiment, and the movement process is not repeated here.

[0055] When the roller 122 enters the low track section 22, the crossbar 123, the first vertical bar 124, the abutment block 126 and the second vertical bar 125 descend under the action of gravity, and the elastic force of the second spring is released, and the clamping opening of the conductive clamp 1 is opened. The crossbar 123, the first vertical bar 124, the abutment block 126 and the second vertical bar 125 of this embodiment can be made of a light material, and the elastic force of the second spring is released to drive the conductive clamp 1 to open.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
