Description

Technical Field

[0001] This utility model relates to the field of starter plate processing technology, specifically to a centering and clamping device for electrolytic cobalt starter plate seed plate. Background Technology

[0002] Electrodeionized cobalt starter sheets are thin plates made of metallic cobalt (Co) or cobalt-based alloys. They are produced by electrowinning with cobalt compound solutions such as cobalt sulfate or cobalt chloride. Attached to a seed plate, they are the front-end product in cobalt electrowinning production. Cobalt plates play an irreplaceable role in many industrial fields due to their unique physicochemical properties, such as high melting point, corrosion resistance, high-temperature stability, and magnetism. Similarly, electrodeionized cobalt starter sheets also possess these properties. However, due to their high hardness, large surface roughness, thinness, and attachment to the seed plate, it is difficult to peel off them using automated equipment under atmospheric pressure.

[0003] Currently, the peeling process for electrolytic cobalt starter wafers mainly relies on manual peeling. The main process is as follows: Workers lift the electrolytic cobalt starter wafer seed plate out of the electrolytic cell and place it on a fiberglass mesh plate. Two workers hold the electrolytic cobalt starter wafer seed plate, while one worker uses a whip or a scraper to scrape the electrolytic cobalt starter wafer on its surface. After prying off the top corner of the electrolytic cobalt starter wafer, the electrolytic cobalt starter wafers located on both sides of the seed plate are manually torn off.

[0004] The drawbacks of this stripping process are that although it can successfully strip the electrolytic cobalt starter sheet, it is labor-intensive for workers, there is a risk of acid mist from the anolyte damaging the human respiratory tract when working on the electrolytic cell, and the work efficiency is low, the stripping time is long, and manual stripping is prone to damaging the electrolytic cobalt starter sheet. Utility Model Content

[0005] The purpose of this invention is to provide a centering and clamping device for electrolytic cobalt starter plates, in order to solve the practical problems of low plate removal and peeling efficiency, high labor intensity and risks in the existing manual plate removal and peeling process.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A cobalt electrowinning seed plate centering clamping device includes a clamping device assembly frame and a base frame disposed below it for mounting the clamping device assembly frame. A support plate frame is connected to the top of the clamping device assembly frame, and a cobalt electrowinning seed plate is connected to the inner side of the support plate frame via a limiting connection. A pressure plate device is provided inside the clamping device assembly frame; the pressure plate device includes:

[0008] The first pressure plate mechanism includes a first guide shaft, a second guide shaft, a first clamping cylinder, and a first pressure plate. The first pressure plate mechanism is symmetrically mounted on both sides of the clamping device assembly frame. The first clamping cylinder drives the first guide shaft, the second guide shaft, and the first pressure plate to move forward symmetrically, and together press the electrolytic cobalt starter plate.

[0009] The second pressure plate mechanism includes a third guide shaft, a second clamping cylinder, and a second pressure plate. The second pressure plate mechanism is symmetrically mounted on both sides of the clamping device assembly frame. The second clamping cylinder drives the third guide shaft and the second pressure plate to move forward symmetrically, and together they clamp the electrolytic cobalt starter plate.

[0010] The support plate clamping mechanism includes a support plate clamp, a spring ejector cylinder, a compression spring, a retraction ejector rod, and a retraction inclined ejector block. The clamping device assembly frame is equipped with a retraction inclined ejector block. The support plate clamp installed on the second pressure plate performs an ejection or retraction action under the action of the compression spring.

[0011] Furthermore, the main body of the combined frame includes a base frame and a clamping device assembly frame connected to the base frame by bolts. The connection has a slotted opening, which can realize the front and rear position adjustment. A tray frame for limiting the placement of the electrolytic cobalt starter plate seed plate is installed on the top of the clamping device assembly frame.

[0012] Furthermore, the first pressure plate mechanism includes four first guide shafts, two second guide shafts, a first clamping cylinder, and a first pressure plate, arranged symmetrically to each other. From bottom to top, they are the first guide shaft, the first clamping cylinder, and the second guide shaft, which are connected to the first pressure plate by threads. The first pressure plate is equipped with rubber pressure blocks for clamping and fixing the lower end of the electrolytic cobalt starter plate.

[0013] Furthermore, the second pressure plate mechanism includes four second clamping cylinders and four second pressure plates, arranged symmetrically to each other. From bottom to top, they are the second clamping cylinder and the third guide shaft, which are connected to the second pressure plate by threads. The second pressure plate is equipped with rubber pressure blocks for clamping and fixing the upper end of the electrolytic cobalt starter plate.

[0014] Furthermore, the support plate clamping mechanism is installed on the second pressure plate, which includes a support plate clamp, a spring ejector cylinder, a compression spring, a retraction ejector rod, and a retraction inclined ejector block. The retraction ejector rod is connected to the support plate clamp guide rod by a thread and is installed inside the spring ejector cylinder. The spring ejector cylinder is equipped with a compression spring, which can eject the support plate clamp. When the second pressure plate mechanism retracts, the retraction ejector rod contacts the inclined surface of the retraction inclined ejector block and begins to retract backward along the inclined surface. The compression spring is compressed, thereby obtaining the potential energy for the next ejection. The support plate clamp disengages from the cobalt starting sheet on the electrolytic cobalt starting sheet seed plate, making way for it to be peeled off by the robotic arm.

[0015] Furthermore, the stroke adjustment nuts at the ends of the first and second clamping cylinders can be adjusted forward and backward to control the cylinder stroke, thereby ensuring that the electrolytic cobalt starter plate is stable and flat after centering and clamping.

[0016] The beneficial effects of this utility model are:

[0017] This invention utilizes a first clamping cylinder to extend and drive a first pressing plate mechanism to move towards the electrolytic cobalt starter plate placed on a tray, fixing its bottom in the center. This action continues until the electrolytic cobalt starter plate curls up at the corner, at which point a robotic arm adsorbs and locks its upper part, peeling off the electrolytic cobalt starter plate and placing it on the conveyor line. Then, the first clamping cylinder drives the first pressing plate mechanism to retract, releasing the bottom of the electrolytic cobalt starter plate. The robotic arm then picks up the empty electrolytic cobalt starter plate after peeling and transports it to the next empty seed plate conveyor line or the peeling abnormality conveyor line. The peeling time is short and no manual operation is required, effectively reducing labor intensity and risk.

[0018] The second clamping cylinder of this utility model extends simultaneously with the first clamping cylinder, driving the second pressure plate mechanism to move towards the electrolytic cobalt starter plate placed on the tray frame, fixing its top in the center. This action continues until the electrolytic cobalt starter plate flicks and tilts, at which point the robotic arm picks up and locks its upper part, then immediately retracts, making room for peeling and facilitating subsequent manual unloading.

[0019] This utility model's support plate clamping mechanism, while the second pressure plate mechanism moves towards the cobalt-concentrated starter plate placed on the tray, allows the retracting push rod to gradually disengage from the retracting inclined push block. The support plate clamp extends under the elastic force of the compression spring, precisely pressing down on the cobalt-concentrated starter plate simultaneously with the second pressure plate mechanism, preventing it from detaching during the next whip-whip lifting process. After the robotic arm adsorbs and locks the upper part of the cobalt-concentrated starter plate, the support plate clamping mechanism retracts along with the second pressure plate mechanism, no longer contacting the starter plate. The retracting push rod gradually moves along the inclined surface of the retracting inclined push block, compressing the spring and causing the support plate clamp to retract, thus creating a path for the robotic arm to peel off the cobalt-concentrated starter plate. This automated continuous operation replaces the manual plate-unloading and peeling process, improving plate-unloading and peeling efficiency. Attached Figure Description

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0028] Please refer to the instruction manual attached. Figures 1-6 As shown, a cobalt electrowinning seed plate centering clamping device includes a clamping device assembly frame 2 and a base frame 1 disposed below it for mounting the clamping device assembly frame 2. A support plate frame 12 is connected to the top of the clamping device assembly frame 2, and a cobalt electrowinning seed plate 10 is connected to the inner side of the support plate frame 12 via a limiting connection. A pressure plate device is provided inside the clamping device assembly frame 2; the pressure plate device includes:

[0029] The clamping plate device mainly includes a first clamping plate mechanism, a second clamping plate mechanism, and a support plate clamping mechanism. The first clamping plate mechanism includes a first guide shaft 3, a second guide shaft 4, a first clamping cylinder 6, and a first clamping plate 8. The first clamping plate mechanism is symmetrically mounted on both sides of the clamping device assembly frame 2. The first clamping cylinder 6 drives the first guide shaft 3, the second guide shaft 4, and the first clamping plate 8 to move forward symmetrically, jointly clamping the cobalt electrolytic starter plate 10. The second clamping plate mechanism includes a third guide shaft 5, a second clamping cylinder 7, and a second clamping plate. 9. The clamping device assembly frame 2 is symmetrically equipped with second pressure plate mechanisms on both sides. The second clamping cylinder 7 drives the third guide shaft 5 and the second pressure plate 9 to move forward symmetrically and jointly press the electrolytic cobalt starter plate 10. The support plate clamping mechanism includes a support plate clamp 11, a spring ejector cylinder 13, a compression spring 14, a retraction ejector rod 15 and a retraction inclined ejector block 16. The clamping device assembly frame 2 is equipped with a retraction inclined ejector block 16. The support plate clamp 11 installed on the second pressure plate 9 performs ejection or retraction actions under the action of the compression spring 14.

[0030] Combination Figure 1 and Figure 2 As shown, the main body of the combined frame includes a base frame 1 and a clamping device assembly frame 2 connected to the base frame 1 by bolts. The connection has a slotted opening, which can realize the front and rear position adjustment. The clamping device assembly frame 2 is equipped with a tray frame 12 for limiting the placement of the electrolytic cobalt starter plate seed plate 10.

[0031] The first pressure plate mechanism includes four first guide shafts 3, second guide shafts 4, first clamping cylinders 6 and first pressure plates 8, which are arranged symmetrically to each other. From bottom to top, they are the first guide shaft 3, the first clamping cylinder 6 and the second guide shaft 4, which are connected to the first pressure plate 8 by threads. The first pressure plate 8 is equipped with rubber pressure blocks for clamping and fixing the lower end of the electrolytic cobalt starter plate 10.

[0032] Similarly, the second pressure plate mechanism includes four of the third guide shaft 5, the second clamping cylinder 7, and the second pressure plate 9, which are arranged symmetrically to each other. From bottom to top, they are the second clamping cylinder 7 and the third guide shaft 5, which are connected to the second pressure plate 9 by threads. The second pressure plate 9 is equipped with rubber pressure blocks for clamping and fixing the upper end of the electrolytic cobalt starter plate 10.

[0033] Combination Figure 3-4 and Figure 6 As shown, in order to ensure that the cobalt starter sheet does not suddenly fall off completely when the whip is swung, the support plate clamping mechanism is installed on the second pressure plate 9. It includes a support plate clamp 11, a spring ejector cylinder 13, a compression spring 14, a retraction rod 15, and a retraction inclined block 16. The retraction rod 15 is connected to the guide rod of the support plate clamp 11 by a thread and is installed in the spring ejector cylinder 12. The compression spring 14 is installed in the spring ejector cylinder 12, which can eject the support plate clamp 11. When the second pressure plate mechanism retracts, the compression spring 14 applies pressure to the support plate clamp 11. The retraction rod 15 contacts the inclined surface of the retraction inclined block (16) and retracts along the inclined surface. The compression spring 14 is compressed to obtain the potential energy for the next ejection. The support plate clamp 11 is separated from the cobalt starter sheet on the cobalt starter sheet seed plate 10, and after clearing the channel, it can be peeled off by the robot arm.

[0034] Combination Figure 5 As shown, the stroke adjustment nut at the end of the cylinder rod of both the first clamping cylinder 6 and the second clamping cylinder 7 can be adjusted forward and backward to control the cylinder stroke, thereby ensuring that the electrolytic cobalt starter plate 10 is stable and flat after centering and clamping.

[0035] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0036] First, the robotic arm clamps the cobalt-electrode seed plate 10 and places it on the tray 12 at the top of the clamping device assembly frame 2. At this time, the cylinders of the first and second pressure plate mechanisms extend simultaneously, so that the first pressure plate 8 and the second pressure plate 9 advance simultaneously to press the four corners of the upper and lower ends of the cobalt-electrode seed plate 10. At the same time, the retraction rod 15 on the second pressure plate 9 is released from the restraint of the retraction inclined block 16, and under the rebound force of the compression spring 14, it drives the support plate clamp 11 to pop out and press the cobalt-electrode seed plate 10 on the surface of the cobalt-electrode seed plate 10.

[0037] The whipping mechanism on the clamping device assembly frame 2 simultaneously whips the cobalt electrode to make it tilt, and the peeling robot arms on both sides, along with the suction cup assembly on the clamp, move forward to the surface of the cobalt electrode, and the suction cups adsorb the cobalt electrode.

[0038] After the system determines that the suction pressure of the suction cup on the electrolytic cobalt starter sheet is sufficient through the sensor, the second clamping cylinder 7 of the second pressure plate mechanism drives the second pressure plate 9 to retract. At the same time, the support plate clamp mechanism retracts along with the second pressure plate mechanism. The support plate clamp 11 no longer contacts the electrolytic cobalt starter sheet. The retraction push rod 15 gradually moves with the inclined surface of the retraction inclined push block 16. The compression spring 14 is compressed, and the support plate clamp 11 retracts accordingly, making way for the robot arm to peel off the electrolytic cobalt starter sheet.

[0039] The peeling robot gripper moves the electrolytic cobalt starter sheet outward at a 15-degree angle. The mechanical gripper flips forward to clamp the inner side of the electrolytic cobalt starter sheet. The peeling robot moves outward to peel off the electrolytic cobalt starter sheet and places it on the conveyor line. The first clamping cylinder 6 then drives the first pressure plate 8 to retract, and the bottom of the electrolytic cobalt starter seed plate 10 is released from restraint. The robot then picks up the empty electrolytic cobalt starter seed plate after peeling and transports it to the next empty seed plate conveyor line or the peeling abnormality conveyor line.

[0040] In summary, this application replaces the manual process of fixing the seed plate and supporting the electrolytic cobalt starter sheet, which not only improves operational efficiency but also shortens the stripping time and effectively reduces the intensity and risk of manual labor.

[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
