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 raised 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 terminal strips with vertically raised structures on the surface, it is difficult to maintain continuous and stable contact with the electrodes. In other words, the electroplating process is prone to short circuit problems, resulting in poor electroplating results. In other words, the electroplating difficulty of terminal strips with raised structures is not comparable to that of flat strips.

[0003] In view of 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 the electroplating process, thereby ensuring the quality of the 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.

[0012] A terminal strip winding device is also provided downstream of the conductive conveying device.

[0013] A current detection device is also provided in the conductive loop to detect the current flowing through the terminal strip;

[0014] When the current fluctuation amplitude is detected to exceed a preset threshold value within a continuous cycle, the horizontal plate is adjusted to move downward to increase the pressing force of the spring.

[0015] The conductive conveying device includes:

[0016] Several linearly arranged sheaves are made of metal, wherein the width of the central groove of the sheave is adapted to the width of the terminal strip;

[0017] The pressing member is arranged along the linearly arranged plurality of groove wheels and is located directly above the central groove of the groove wheels; the distance between the pressing member and the bottom of the central groove of the groove wheels is less than the height of the terminal strip, so that when the terminal strip is conveyed along the groove wheels, the lower portion of the pressing member exerts a downward pressure on the terminal strip;

[0018] The second electrode is slidably connected to one or more of the sheaves.

[0019] The width of the middle groove of the groove wheel is adapted to the width of the terminal strip, which means that the width of the middle groove of the groove wheel is equal to the width of the terminal strip, or slightly larger than the width of the terminal strip, to ensure that the terminal strip can be transported along the middle groove of the groove wheel.

[0020] 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.

[0021] Optionally, the depth of the central groove of the sheave 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 central groove of the sheave, so that the pressing component can be embedded in the central groove of the sheave.

[0022] The height of the terminal strip refers to the height of the terminal strip when it is unfolded in the horizontal direction.

[0023] The pressing component adopts a rectangular structure, and a smooth guiding portion is provided at the bottom of the pressing component at the feeding end of the metal strip to guide the raised structure on the upper part of the terminal strip to enter between the pressing component and the groove wheel.

[0024] The lower surface of the pressing component is a plane and is made of wear-resistant material.

[0025] The pressing component is made of insulating material.

[0026] The conductive conveying device further includes a first vertical plate and a second vertical plate, and the sheave is installed between the first vertical plate and the second vertical plate through a bearing.

[0027] The height of the second vertical plate is higher than that of the pressing component, and the pressing component is connected to the second vertical plate via two elastic connection structures.

[0028] The elastic connection structure includes a hinge plate, a spring and a sliding rod. The hinge plate is rotatably connected to the downward pressing component. The sliding rod is fixedly connected to the upper part of the hinge plate. The upper part of the sliding rod is slidably connected to the horizontal plate on the second vertical plate. The spring is sleeved on the outside of the sliding rod and is located between the hinge plate and the horizontal plate.

[0029] The second electrode is a conductive copper sheet connected to the bottom plate, and the top of the conductive copper sheet abuts against the groove wheel; correspondingly, the first vertical plate and the second vertical plate are respectively fixedly connected to the bottom plate;

[0030] Among them, the bearings of the sheave are ceramic bearings.

The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] like Figure 2-3 As shown, the present invention provides an electroplating system for a terminal strip having a protruding structure, comprising:

[0041] The electroplating tank 11 is filled with an electroplating solution and a first electrode is disposed in the electroplating solution. The first electrode is disposed on the wall of the electroplating tank 11 and is capable of connecting the electroplating solution in the electroplating tank 11 to an external power source. The terminal strip 10 can enter the electroplating tank and exit the electroplating tank to a downstream process location at a uniform speed.

[0042] The hot air return 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 return 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 that the metal strip 10 maintains a dry surface when entering the downstream process position;

[0043] The conductive conveying device 13 is located downstream of the hot air return device and is used to clamp and convey the terminal strip 10. The conductive conveying device 13 is provided with a second electrode electrically connected to the terminal strip 10; the second electrode is connected to an external power supply through an insulating bottom plate; during the process of the conductive conveying device 13 clamping and conveying the terminal strip 10, it can maintain a continuous and stable electrical connection with the second electrode, thereby maintaining a stable conductive state of the electrical circuit;

[0044] A conductive loop is formed by the first electrode, the terminal strip 10 , the electroplating solution, the sheave of the conductive conveying device 13 and the second electrode.

[0045] The electroplating system of the terminal strip with a raised structure provided by the present invention is composed of a first electrode, a terminal strip, an electroplating solution, a groove wheel of a conductive conveying device and a second electrode to form a conductive circuit. The terminal strip is tightly connected to the second electrode through the conductive conveying device, so that the terminal strip in the electroplating tank can complete the electroplating work under a stable current environment, thereby achieving a better electroplating effect.

[0046] The electroplating tank 11 is 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.

[0047] A terminal strip unwinding device is also provided upstream of the electroplating tank.

[0048] A terminal strip winding device is also provided downstream of the conductive conveying device.

[0049] A current detection device (not shown in the figure) is also provided in the conductive loop to detect the current flowing through the terminal strip;

[0050] 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.

[0051] 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 spring's elastic force greater, and making the contact between the terminal strip 11 and the groove wheel 1 closer.

[0052] The current detection device may be an ammeter connected in series in the conductive loop.

[0053] The conductive conveying device includes:

[0054] Several linearly arranged sheaves 1 are made of metal, wherein the width of the central groove of the sheave 1 is adapted to the width of the terminal strip 10. The sheave 1 provides rotational support for the terminal strip 10, reduces frictional resistance between the terminal strip 10 and the sheave 1, and prevents the terminal strip from being stretched and deformed and damaged during transportation. The sheave 1 is made of metal, thereby establishing a conductive structure between the terminal strip 10 and the second electrode 3, thereby forming a conductive loop between the electrodes in the electroplating tank (the terminal strip 10 must pass through the electroplating tank before entering the sheave).

[0055] The pressing component 2 is arranged along the linearly arranged plurality of groove wheels 1 and is located directly above the central groove of the groove wheel 1; the distance between the pressing component 2 and the bottom of the central groove of the groove wheel 1 is less 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;

[0056] 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 the power supply through a wire, and the power supply is also connected to the electrodes in the electroplating tank.

[0057] 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.

[0058] 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.

[0059] Optionally, the depth of the central groove of the sheave 1 is smaller 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. In this case, the terminal strip 10 does not completely enter the central groove, that is, there is a certain distance between the rims at both ends of the sheave and the pressing component 2. The width of the pressing component 2 can be wider than the width of the central groove as long as it meets the downward pressure of the terminal strip 10.

[0060] Optionally, the depth of the central groove of the sheave 1 is greater than the height of the terminal strip 10, and correspondingly, the width of the pressing member 2 is less than or equal to the width of the central groove of the sheave 1, so that the pressing member 2 can be embedded in the central groove of the sheave 1. In this case, the terminal strip 10 almost entirely falls into the central groove. In this case, after the pressing member 2 presses the terminal strip 10, the two ends of the pressing member 2 should not contact the sheave, thus requiring a limit on the width of the pressing member.

[0061] The height of the terminal strip 10 refers to the height of the terminal strip 10 when it is unfolded in the horizontal direction.

[0062] The pressing member 2 is a rectangular structure, and a smooth guide portion is provided at the bottom of the pressing member 2 at the feeding end of the metal strip to guide the raised structure on the upper portion of the terminal strip 10 into between the pressing member 2 and the groove wheel 1. Since the raised structure on the terminal strip 10 is not continuous but intermittent, the structural design of the guide portion can prevent the raised structure from colliding with the side wall of the pressing member 2, thereby preventing the terminal strip 10 and the pressing member 2 from getting stuck.

[0063] The lower surface of the pressing component 2 is flat and 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 flat.

[0064] The pressing component 2 is made of insulating material.

[0065] 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.

[0066] 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.

[0067] The elastic connection structure includes a hinged plate 8, a spring (omitted in the figure), and a slide bar 9. The hinged plate 8 is rotatably connected to the downward pressing member 2. The slide bar 9 is fixedly connected to the upper portion of the hinged plate 8. The upper portion of the slide bar 9 is slidably connected to the cross plate 6 on the second vertical plate 5. The spring is sleeved on the outside of the slide bar 9 and is located between the hinged plate 8 and the cross plate. The elastic connection structure applies an elastic force to the downward pressing member, thereby causing the downward pressing member to press against the upper portion of the terminal strip 10, so that the terminal strip and the groove wheel are tightly fitted.

[0068] The pressing plate 6 is connected to the second vertical plate 5 by a sliding connection, and a corresponding sliding groove structure needs to be opened on the second vertical plate 5, and can be connected to the second vertical plate 5 by screw locking.

[0069] The second electrode 3 is a conductive copper sheet connected to the bottom plate 7, and the top of the conductive copper sheet abuts against the sheave 1; correspondingly, the first vertical plate 4 and the second vertical plate 5 are fixedly connected to the bottom plate 7 respectively;

[0070] Among them, 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.

[0071] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0072] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
