Description

Technical Field

[0001] The present invention relates to the technical field of production of new energy electric vehicle accessories, and in particular to an electroplating system for a terminal strip with a protruding structure of a cold-pressed terminal for electrical connection. Background Art

[0002] The terminal structure of the cold-pressed terminal used in new energy vehicles needs to be processed into a special shape, forming a vertically upward convex structure on the surface of the terminal strip (reference Figure 1 ). After processing the terminal structure, electroplating is usually required to ensure its anti-oxidation and corrosion resistance. However, for the terminal strip with a vertically raised structure on the surface, it is difficult to maintain continuous and stable contact with the electrode, which means that the electroplating process is prone to short circuit problems, resulting in poor electroplating effect. In other words, the difficulty of electroplating a terminal strip with a raised structure cannot be compared with that of a flat strip.

[0003] Based on the above problems, the present invention provides a method for ensuring continuous and stable contact between a terminal strip having a protruding structure and an electrode during an electroplating process, thereby ensuring the quality of electroplating. Summary of the invention

[0004] The technical problem to be solved by the embodiments of the present invention is to provide an electroplating system for a terminal strip with a protruding structure, so as to solve the problem that the electroplating effect of the terminal strip is poor due to discontinuous circuit contact during the electroplating process.

[0009] A current detection device is also provided in the conductive loop for detecting the current flowing through the terminal strip; When the current fluctuation amplitude is detected to exceed a preset threshold value in a continuous cycle, the horizontal plate is adjusted to move downward to increase the pressing force of the spring.

[0010] The conductive conveying device comprises: A plurality of linearly arranged groove wheels, the groove wheels are made of metal material, wherein the width of the middle groove of the groove wheel is adapted to the width of the terminal strip; The pressing component is arranged along a plurality of linearly arranged groove wheels and is located directly above the middle groove of the groove wheels; the distance between the pressing component and the bottom of the middle groove of the groove wheel is less than the height of the terminal strip, so that when the terminal strip is conveyed along the groove wheel, the lower part of the pressing component has a downward pressure on the terminal strip; The second electrode is slidably connected to one or more of the sheaves.

[0011] The width of the middle groove of the groove wheel is adapted to the width of the terminal material strip, which means that the width of the middle groove of the groove wheel is equal to the width of the terminal material strip, or slightly larger than the width of the terminal material strip, to ensure that the terminal material strip can be transported along the middle groove of the groove wheel.

[0012] The depth of the middle groove of the groove wheel is smaller than the height of the terminal strip, and correspondingly, the width of the pressing component is adapted to the width of the terminal strip.

[0013] Optionally, the depth of the middle groove of the groove wheel is greater than the height of the terminal strip, and correspondingly, the width of the pressing component is less than or equal to the width of the middle groove of the groove wheel, so that the pressing component can be embedded in the middle groove of the groove wheel.

[0014] The height of the terminal strip refers to the height of the terminal strip when it is unfolded in the horizontal direction.

[0015] The pressing component adopts a rectangular structure, and a smooth guiding part is arranged at the bottom of the pressing component at the feeding end of the metal strip to guide the protruding structure on the upper part of the terminal strip to enter between the pressing component and the groove wheel.

[0016] The lower surface of the pressing component is a plane and is made of wear-resistant material.

[0017] The pressing component is made of insulating material.

[0018] The conductive conveying device further comprises a first vertical plate and a second vertical plate, and the groove wheel is installed between the first vertical plate and the second vertical plate through a bearing.

[0030] like Figure 2-3 As shown, the present invention provides an electroplating system for a terminal strip having a protruding structure, comprising: The electroplating tank 11 is filled with an electroplating solution, and a first electrode is arranged in the electroplating solution; the first electrode is arranged on the wall of the electroplating tank 11, and the electroplating solution in the electroplating tank 11 can be connected to an external power source; the terminal strip 10 can enter the electroplating tank at a uniform speed and leave the electroplating tank to a downstream process position; The hot air back-blowing device 12 is installed at the terminal strip outlet of the electroplating tank 11, and can blow hot air in the opposite direction of the conveying direction of the terminal strip 11; the hot air back-blowing device 12 can blow the electroplating solution on the terminal strip 10 back into the electroplating tank, thereby not only reducing the electroplating solution residue on the terminal strip 10 and recycling the material, but also quickly drying the metal strip 10, so as to keep a dry surface when the metal strip 10 enters the downstream process position; The conductive conveying device 13 is located downstream of the hot air blowing device and is used to clamp and convey the terminal material strip 10. The conductive conveying device 13 is provided with a second electrode electrically connected to the terminal material strip 10; the second electrode is connected to an external power source through an insulating bottom plate; during the process of the conductive conveying device 13 clamping and conveying the terminal material strip 10, it can maintain a continuous and stable electrical connection with the second electrode, so that the electrical circuit maintains a stable conductive state; A conductive loop is formed by the first electrode, the terminal strip 10, the electroplating solution, the groove wheel of the conductive conveying device 13 and the second electrode.

[0031] The electroplating system of the terminal material strip with a protruding structure provided by the present invention comprises a first electrode, a terminal material strip, an electroplating solution, a groove wheel of a conductive conveying device and a second electrode to form a conductive circuit. The terminal material strip is tightly connected to the second electrode through the conductive conveying device, so that the terminal material strip in the electroplating tank can complete the electroplating work under a stable current environment, thereby achieving a better electroplating effect.

[0032] The electroplating tank 11 is of a rectangular structure, and the terminal strip 10 passes through the electroplating tank 11 along the longitudinal direction of the electroplating tank 11, so that the electroplating time of the terminal strip 11 can be greatly extended, resulting in a better electroplating effect.

[0033] A terminal strip unwinding device is also provided upstream of the electroplating tank.

[0034] A terminal strip winding device is also provided downstream of the conductive conveying device.

[0035] A current detection device (not shown in the figure) is also provided in the conductive loop for detecting the current flowing through the terminal strip; When the current fluctuation amplitude is detected to exceed a preset threshold value (the threshold value is set according to usage needs, such as 20% of the working current) within a continuous cycle, the horizontal plate is adjusted to move downward to increase the compression force of the spring.

[0036] By adjusting the horizontal plate downward, the distance between the horizontal plate 6 and the hinge 8 is reduced, so that the spring can be further compressed, making the elastic force of the spring stronger, and making the contact between the terminal strip 11 and the groove wheel 1 closer.

[0037] The current detection device may be an ammeter connected in series in the conductive loop.

[0038] The conductive conveying device comprises: A plurality of groove wheels 1 are arranged linearly, and the groove wheels 1 are made of metal material, wherein the width of the middle groove of the groove wheel 1 is adapted to the width of the terminal material strip 10; the groove wheel 1 is used to provide rotation support for the terminal material strip 10, reduce the friction resistance between the terminal material strip 10 and the groove wheel 1, and avoid the deformation and damage of the terminal material strip due to stretching during the conveying process; the groove wheel 1 is made of metal material, so that a conductive structure can be established between the terminal material strip 10 and the second electrode 3, so that a conductive loop is formed between the electrodes in the electroplating tank (the terminal material strip 10 must pass through the electroplating tank before entering the groove wheel); The pressing component 2 is arranged along a plurality of linearly arranged groove wheels 1 and is located directly above the middle groove of the groove wheel 1; the distance between the pressing component 2 and the bottom of the middle groove of the groove wheel 1 is smaller than the height of the terminal strip 10, so that when the terminal strip 10 is conveyed along the groove wheel 1, the lower part of the pressing component 2 exerts a downward pressure on the terminal strip 10; the pressing component 2 exerts a downward pressure on the terminal strip 10, thereby promoting a close fit between the terminal strip 10 and the groove wheel 1; The second electrode 3 is slidably connected to one or more groove wheels 1, and the other end of the second electrode is connected to a power source through a wire, and the power source is simultaneously connected to the electrodes in the electroplating tank.

[0039] The electroplating system of the terminal strip with a raised structure provided by the present invention can ensure that the terminal strip 10 can be stably conveyed forward after the electroplating is completed through the structure of the pressing component 2 and the groove wheel 1, and maintain a stable electrical connection between the terminal strip 10 and the second electrode 3 during the conveying process, thereby ensuring the smooth progress of electroplating and conveying and improving the electroplating quality.

[0040] The width of the middle groove of the groove wheel 1 is adapted to the width of the terminal strip 10 , which means that the width of the middle groove of the groove wheel 1 is equal to the width of the terminal strip 10 , or slightly larger than the width of the terminal strip 10 , to ensure that the terminal strip 10 can be transported along the middle groove of the groove wheel 1 .

[0041] Optionally, the depth of the middle groove of the groove wheel 1 is less than the height of the terminal strip 10, and correspondingly, the width of the pressing component 2 is adapted to the width of the terminal strip 10. At this time, the terminal strip 10 does not completely enter the middle groove, that is, there is a certain distance between the rims at both ends of the groove wheel and the pressing component 2, and the width of the pressing component 2 can be wider than the width of the middle groove as long as it meets the downward pressure of the terminal strip 10.

[0042] Optionally, the depth of the middle groove of the groove wheel 1 is greater than the height of the terminal strip 10, and correspondingly, the width of the pressing component 2 is less than or equal to the width of the middle groove of the groove wheel 1, so that the pressing component 2 can be embedded in the middle groove of the groove wheel 1. At this time, the terminal strip 10 almost falls into the middle groove, and at this time, it is required that after the pressing component 2 presses the terminal strip 10, the two ends of the pressing component 2 should not contact the groove wheel, so it is necessary to limit the width of the pressing component.

[0043] The height of the terminal strip 10 refers to the height of the terminal strip 10 when it is unfolded along the horizontal direction.

[0044] The pressing component 2 adopts a rectangular structure, and a smooth guiding part is provided at the bottom of the pressing component 2 at the feeding end of the metal strip to guide the raised structure on the upper part of the terminal strip 10 to enter between the pressing component 2 and the groove wheel 1. Since the raised structure on the terminal strip 10 is not continuous but an intermittent raised structure, the structural design of the guiding part can prevent the raised structure from colliding with the side wall of the pressing component 2, thereby preventing the terminal strip 10 and the pressing component 2 from being stuck.

[0045] The lower surface of the pressing component 2 is a plane and is made of wear-resistant material. Since the pressing component 2 is different from the groove wheel 1, the main function of the pressing component 2 is to exert continuous downward force, so the lower surface of the pressing component is a plane.

[0046] The pressing component 2 is made of insulating material.

[0047] The conductive conveying device provided by the present invention also includes a first vertical plate 4 and a second vertical plate 5. The groove wheel 1 is installed between the first vertical plate 4 and the second vertical plate 5 through a bearing. The first vertical plate 4 and the second vertical plate 5 provide support and limitation for multiple groove wheels 1 to ensure the linear arrangement of the groove wheels 1.

[0048] The height of the second vertical plate 5 is higher than that of the pressing component 2 , and the pressing component 2 is connected to the second vertical plate 5 via two elastic connection structures.

[0049] The elastic connection structure includes a hinged piece 8, a spring (omitted in the figure) and a slide bar 9. The hinged piece 8 is rotatably connected to the pressing component 2. The slide bar 9 is fixedly connected to the upper part of the hinged piece 8. The upper part of the slide bar 9 is slidably connected to the cross plate 6 on the second vertical plate 5. The spring is sleeved outside the slide bar 9 and is located between the hinged piece 8 and the cross plate. The elastic connection structure applies elastic force to the pressing component, thereby causing the pressing component to press on the upper part of the terminal strip 10, so that the terminal strip and the groove wheel are closely fitted.

[0050] The pressing plate 6 is connected to the second vertical plate 5 by a sliding connection, and a sliding groove structure needs to be opened on the second vertical plate 5 accordingly, and can be connected to the second vertical plate 5 by screw locking.

[0051] The second electrode 3 is a conductive copper sheet, which is connected to the bottom plate 7, and the top of the conductive copper sheet abuts against the groove wheel 1; correspondingly, the first vertical plate 4 and the second vertical plate 5 are fixedly connected to the bottom plate 7 respectively; The bearings of the sheave 1 are ceramic bearings; correspondingly, the bottom plate 7, the first vertical plate 4, and the second vertical plate 5 can be made of insulating materials, so that the bottom plate and the fixed platform below it are insulated from the charged structures such as the second electrode.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
