Description

Technical Field

[0001] This application relates to the technical field of working devices, and particularly to an electroplating tooling for battery steel shells. Background Art

[0002] Currently, in order to improve the durability of battery steel shells, a corrosion-resistant material is usually electroplated on the surface of the battery steel shells. For steel shells with a relatively small volume, they often have a relatively deep inner cavity. For example, for a cylindrical battery steel shell, in order to facilitate contact with the electrode, the opening of the battery steel shell is usually facing downwards. This easily leaves air at the inner top of the battery steel shell. Even when it is completely immersed in the electrolyte, the inner wall of the battery steel shell may not be able to fully contact the electrolyte, resulting in the electroplating material not being able to fully cover all surfaces of the battery steel shell. Summary of the Invention

[0003] The purpose of this application is to provide an electroplating tooling that can completely wrap the battery steel shell with a plating layer.

[0004] To achieve the above purpose, this application provides an electroplating tooling for battery steel shells: including an electroplating tank, an electrode sleeve is provided on the inner wall of the electroplating tank, an air supply mechanism, a picking and placing mechanism, and a conveying mechanism are provided outside the electroplating tank. The conveying mechanism is adapted to convey a battery steel cylinder with its opening facing downwards. The air supply mechanism includes a conductive pipe passing through the electrode sleeve, and the conductive pipe extends upward from the bottom and is adapted to be inserted into the battery steel cylinder. The upper end of the conductive pipe is submerged below the liquid level of the electrolyte in the electroplating tank. The picking and placing mechanism is adapted to pick up the unplated battery steel cylinder from the conveying mechanism and then place the electroplated battery steel cylinder back on the conveying mechanism. An electrode rib plate electrically connected to the battery steel cylinder is also provided on the picking and placing mechanism as another cathode of the electroplating tooling.

[0005] As a preference, there are several conductive pipes, and several conductive pipes are arranged in parallel at equal distances. The air supply mechanism includes a flow distribution box, and an air supply pump is provided on the outer side of the flow distribution box. The air supply pump supplies air to all the conductive pipes through the flow distribution box, and uses pressurized air to generate bubbles to flush the electrolyte to the inner wall of the battery steel cylinder.

[0006] As a preference, the picking and placing mechanism includes a vertical telescopic device fixedly connected to the upper surface of the flow distribution box. The movable end of the vertical telescopic device is fixedly connected with a horizontal telescopic device through a lifting frame. The movable end of the horizontal telescopic device is fixedly connected with an electromagnetic suction plate through a translation plate. The electromagnetic suction plate has an excitation coil inside, which generates a magnetic force after being energized and is adapted to suck up the battery steel cylinder, which can effectively reduce the contact amount between the picking and placing mechanism and the electrolyte, thereby reducing the pollution of the electrolyte to the picking and placing mechanism.

[0007] As a preference, the electrode rib plate is fixedly connected between the translation plate and the electromagnetic suction plate to improve the connection strength between the electromagnetic suction plate and the translation plate.

[0008] As a preference, one side of the electroplating bath close to the air supply mechanism is the back plate. The electrode sleeve is fixedly connected to the inner side surface of the back plate. The electroplating bath is provided with a sunken groove on the upper end surface of the back plate to leave more movement space for the lifting frame.

[0009] As a preference, both the vertical telescopic device and the horizontal telescopic device adopt air cylinders, which have simple structures, fast responses and low usage costs.

[0010] As a preference, it includes a bottom plate. The conveying mechanism, the electroplating bath and the air supply mechanism are all fixedly connected to the bottom plate. The conveying mechanism includes a frame fixedly connected to the bottom plate. The upper end of the frame is movably connected with a conveyor belt through rollers to hold the battery steel cylinder and move together.

[0011] As a preference, a distribution box is further arranged on the bottom plate. The air supply pump, the drive unit of the conveying mechanism, the electrode sleeve and the electrode rib plate are all electrically connected to the circuit board in the distribution box for power supply and control.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows:

[0013] (1) By arranging the air supply mechanism, bubbles are generated by the conductive pipe, enabling the electrolyte to fully contact the inner wall of the battery steel cylinder, so that all surfaces of the battery steel cylinder can obtain sufficient coatings to improve the surface corrosion resistance, thereby enhancing the safety and durability;

[0014] (2) By also arranging an electrode rib plate structure as the cathode on the picking and placing mechanism, the battery steel cylinder that does not contact the conductive pipe can also obtain electrons, thereby reducing the coating ions in the electrolyte to obtain a coating; on the other hand, the picking and placing mechanism grabs the battery cylinder through a controllable magnetic attraction effect, effectively reducing the contact pollution with the electrolyte.

[0028] As Figure 1-8 The electroplating tooling for the battery steel shell shown in the figure includes a cuboid electroplating tank 3. An electrode sleeve 603 is provided on the inner wall of the electroplating tank 3. An air supply mechanism 6, a picking and placing mechanism 7, and a conveying mechanism 2 are provided outside the electroplating tank 3. One side of the electroplating tank 3 close to the air supply mechanism 6 is a back plate 301. The electrode sleeve 603 is fixedly connected to the inner side of the back plate 301, near the bottom of the electroplating tank 3, and is submerged below the liquid level of the electrolyte.

[0029] This electroplating tooling also has a corrosion-resistant bottom plate 1. The conveying mechanism 2, the electroplating tank 3, and the air supply mechanism 6 are all fixedly connected to the upper surface of the bottom plate 1. The conveying mechanism 2 includes a frame 201 fixedly connected to the bottom plate 1. A conveyor belt 202 is movably connected to the upper end of the frame 201 through rollers, and the rollers are driven by a driving unit on the frame 201.

[0030] The conveying mechanism 2 is used to convey the battery steel cylinder 4. The openings of the battery steel cylinder 4 face downward before and after electroplating. The air supply mechanism 6 includes a conductive tube 604 passing through the electrode sleeve 603. Both the conductive tube 604 and the electrode sleeve 603 are made of conductive materials and are in contact with each other. The conductive tube 604 extends upward from the bottom and can just be inserted into the battery steel cylinder 4 with the opening facing downward. The upper end of the conductive tube 604 also needs to be submerged below the liquid level of the electrolyte in the electroplating tank 3 so that the battery steel cylinder 4 can be completely submerged in the electrolyte. There are several conductive tubes 604, which can support multiple battery steel cylinders 4 at the same time, helping to improve the electroplating efficiency. The several conductive tubes 604 are arranged in parallel at equal distances, facilitating the simultaneous picking and placing of all the battery steel cylinders 4. The air supply mechanism 6 includes a flow distribution box 602 fixedly connected to the bottom plate 1. An air supply pump 601 is provided outside the flow distribution box 602. The air supply pump 601 supplies air to all the conductive tubes 604 through the flow distribution box 602, so that the electrolyte can fully contact the inner wall of the battery steel cylinder 4.

[0031] The pick-and-place mechanism 7 is used to remove the unplated battery steel cylinder 4 from the conveying mechanism 2, and then put the plated battery steel cylinder 4 back to the conveying mechanism 2. The specific structure of the pick-and-place mechanism 7 includes a vertical telescope 701 fixedly connected to the upper surface of the shunt box 602. The vertical telescope 701 adopts a cylinder. The movable end of the vertical telescope 701 is fixedly connected to a horizontal telescope 703 through a lifting frame 702. The horizontal telescope 703 also adopts a cylinder. The characteristics of the cylinder are simple structure, fast action, and low energy consumption. It is very suitable for movements that only require two position control points. The movable end of the horizontal telescope 703 is fixedly connected to the electromagnetic suction plate 705 through the translation plate 704. The electromagnetic suction plate 705 has an excitation coil inside. When powered on, it can generate magnetic force, thereby sucking up the battery steel cylinder 4. After power is off, the magnetic force disappears, and the battery steel cylinder 4 will naturally separate from the electromagnetic suction plate 705 under the action of its own gravity. The electroplating pool 3 is provided with a sinking groove 302 on the upper end surface of the back plate 301 to make way for the lifting frame 702, so that the lifting frame 702 can be lowered lower, so that the electromagnetic suction plate 705 can more easily suck up the battery steel cylinder 4 without direct contact.

[0032] The pick-and-place mechanism 7 is also provided with an electrode rib 706 electrically connected to the battery steel cylinder 4. Even if the battery steel cylinder 4 is sucked up and no longer in contact with the conductive tube 604, electrons can be obtained. The electrode rib 706 is fixedly connected between the translation plate 704 and the electromagnetic suction plate 705. In fact, the bottom surface of the electromagnetic suction plate 705 is made of conductive material, and the other sides are insulating materials for protecting the excitation coil inside the electromagnetic suction plate 705. The electrode rib 706 is electrically connected to the bottom surface of the electromagnetic suction plate 705. A distribution box 5 is also provided on the bottom plate 1. The drive units of the air supply pump 601 and the conveying mechanism 2, as well as the electrode sleeve 603 and the electrode rib 706 are all electrically connected to the circuit board in the distribution box 5. Automatic control can be achieved through a software program. Of course, the pneumatic systems of the vertical telescope 701 and the horizontal telescope 703 are also controlled through the circuit board of the distribution box 5.

[0033] Working principle: First, the electromagnetic suction plate 705 of the picking and placing mechanism 7 picks up multiple battery steel cylinders 4 on the conveying mechanism 2, transfers them above the electroplating bath 3, the electromagnetic suction plate 705 is powered off, the battery steel cylinder 4 loses the magnetic suction force, and drops under its own gravity and sleeves outside the conductive tube 604 until it completely sinks into the electrolyte and contacts the conductive tube 604. At this time, the liquid level of the electrolyte inside the battery steel cylinder 4 will be lower than the upper end of the conductive tube 604. Since the conductive tube 604 is in contact with the electrode sleeve 603 serving as the cathode, after power-on, the plating ions in the electrolyte will be reduced and adsorbed on the surface of the battery steel cylinder 4. When the plating thickness of the battery steel cylinder 4 is sufficient, it will be picked up by the electromagnetic suction plate 705 again. At this time, the liquid level height inside the battery steel cylinder 4 will recover and be higher than the upper end of the conductive tube 604. Subsequently, the electrode rib 706 is powered on to serve as another electroplating cathode to provide electrons to the battery steel cylinder 4. At the same time, the air supply mechanism 6 is actuated, and the air supply pump 601 pressurizes the air and discharges it from the upper end of the conductive tube 604 to generate bubbles in the electrolyte, pushing up the electrolyte and splashing it onto the inner wall of the battery steel cylinder 4. In this way, all positions on the inner wall of the battery steel cylinder 4 can fully adsorb the reduced electroplating material. When the inner wall of the battery steel cylinder 4 adsorbs a sufficient thickness of the plating layer, the picking and placing mechanism 7 can place the battery steel cylinder 4 back on the conveying mechanism 2 to enter the next process.
