Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrode wire processing, specifically to an automatic sharpening mechanism for ultra-fine electrode wires. Background Technology
[0002] Electrode wire materials are widely used in cable processing and other fields due to their comprehensive mechanical properties such as high strength, good ductility, and high stability, as well as their good electrical and thermal conductivity. As an important metal wire material, electrode wire has the characteristics of low resistivity and good conductivity. It can be used to make motor windings, electrical connection wires, printed circuit boards, etc., and can also be made into heat dissipation components such as heat sinks and radiators. It is widely used in the electrical and electronic industry.
[0003] While existing electrode wire production equipment has overcome the inefficiency of traditional manual electrode wire drawing methods, it can only perform simple diameter reduction processing and cannot meet the needs of producing electrode wires of different shapes. Alternatively, it may use mechanical roll calendering, which results in a single forming process and cannot fully improve the mechanical properties of the electrode wire. More importantly, for electrode wires with smaller diameters, the existing electrode wire processing equipment is difficult to operate and cannot meet production needs for further sharpening.

[0041] The following is a detailed description of this novel experimental device with reference to the accompanying drawings:
[0042] Figure 1-8 This invention discloses an automatic sharpening mechanism for ultra-fine electrode wires, comprising: a feeding device 1; an electrode wire fixing device 2, which is equipped with rotatable electric grippers 21, and has two sets of grippers 21 symmetrically arranged about the feeding device 1; and further comprising:
[0043] The electrode wire polishing device 3 is arranged on the symmetrical line of the two sets of electrode wire fixing devices 2. The structure of the electrode wire polishing device 3 includes: a lifting and sliding unit 31, which is placed relative to the material picking device 1.
[0044] A grinding wheel unit 32 is mounted on the grinding base plate 311 of the lifting and sliding unit 31. The grinding wheel unit 32 is connected to the output shaft of the grinding rotary motor 4. Two grinding wheels 5 with their sides in contact are rotatably mounted on the grinding wheel unit 32, and a wedge-shaped gap 51 is formed between the grinding wheels 5.
[0045] Working principle:
[0046] Before sharpening and preparing for the operation:
[0047] The operator then takes a section of electrode wire 6 that needs to be sharpened, which is picked up by the material taking device 1 and placed directly above the electrode wire grinding device 3. The electrode wire fixing devices 2 on both sides then clamp the electrode wire 6 with the electric gripper 21. After the two ends of the electrode wire are fixed, the material taking device 1 releases the electrode wire 6 and moves to a safe position. Then, the grinding unit 32 adjusts the distance of the wedge gap 51 between the two grinding wheels 5 to ensure that the electrode wire 6 and the wedge gap 51 are on the same vertical plane.
[0048] Sharpening operation:
[0049] The electrode wire fixing device 2 is started by an external power source, causing the electric gripper 21 to rotate along with the electrode wire 6. At this time, the grinding rotary motor 4 is started by an external power source, causing the electrode wire grinding device 3 to drive the two grinding wheels 5 to rotate at high speed. The lifting sliding unit 31 is started by an external power source, causing the grinding base plate 311 to move, so that the entire electrode wire grinding device 3 slowly moves closer to the electrode wire 6, and always ensures that the electrode wire 6 is clamped in the wedge gap 51 between the two grinding wheels 5.
[0050] During the movement, the rotation direction of the grinding wheel 5 is perpendicular to the rotation direction of the electrode wire 6. The lifting and sliding unit 31 controls the two grinding wheels 5 to move upward with a feed amount of 0.01mm, and at the same time move laterally to the right to form an interpolation motion, thereby achieving the sharpening treatment of the tip of the electrode wire 6.
[0051] Homework completed:
[0052] After the two grinding wheels 5 finish sharpening the tip of the electrode wire 6, the lifting and sliding unit 31 controls the two grinding wheels 5 to move downward to a safe distance to avoid further damage to the sharpened electrode wire 6. At the same time, the electrode wire fixing device 2 is turned off, so that the electric gripper 21 stops driving the electrode wire 6 to rotate. Then the material picking device 1 moves back to directly above the electrode wire 6 and takes the sharpened electrode wire 6 out of the electric gripper 21. At this point, the entire sharpening operation of the electrode wire 6 is completed.
[0053] in,
[0054] ① The grinding wheel 5 is a high-grit grinding disc, which makes the surface of the electrode wire 6 smooth and uniform after grinding. In addition, a wedge-shaped gap 51 is formed between the grinding wheels 5, which increases the grinding area, makes the grinding more uniform, and can also meet the sharpening requirements, ensuring that the tip of the electrode wire 6 is conical after grinding.
[0055] ② In actual use, in order to ensure the smooth operation of the lifting and sliding unit 31, the lifting and sliding unit 31 not only has a high-precision feed amount, which can accurately control the grinding wheel 5 to perform interpolation motion to complete the conical grinding, but also has limit control and alarm functions.
[0056] ③ In actual use, the motor selected for electrode wire fixing device 2 has a speed of 1000 rpm, and the direction of rotation of the electrode wire 6 driven by it is perpendicular to the rotation direction of the grinding wheel 5.
[0057] ④ The electric gripper 21 was selected from MISUMI, and the specific model is:
[0058] E-ELGPRD8-023-T0-L1, specific parameters are shown in the table below:
[0059]
[0060] Table 1 - Parameter Data of Electric Gripper 21
[0061] As described above, the structure of the material handling device 1 includes:
[0062] The second electric lead screw slide 11 has a guide post 13 on its slide 12;
[0063] The cylinder support plate 14 has one end fixed to the guide post 13 and the other end provided with a telescopic cylinder 15. The output shaft of the telescopic cylinder 15 is connected to a pneumatic gripper 16.
[0064] Working principle:
[0065] Before sharpening and preparing for the operation:
[0066] The operator then sharpens a section of electrode wire 6, which is then fixed and secured by the pneumatic gripper 16. The telescopic cylinder 15 is activated by an external power source, causing the electrode wire 6 to move downwards until it is at the same level as the electrode wire fixing device 2. After both ends of the electrode wire 6 are secured, the telescopic cylinder 15 drives the pneumatic gripper 16 to retract. At this time, the cylinder support plate 14 is moved horizontally by the guide post 13 on the slide table 12 and driven by the second electric screw slide table 11, so that the material handling device 1 moves to a safe position.
[0067] After completing the assignment,
[0068] The second electric lead screw slide 11 then drives the entire device back to the upper position of the electrode wire 6, and the telescopic cylinder 15 drives the pneumatic gripper 16 to move back to the electrode wire 6 to clamp it, and take out the sharpened electrode wire 6.

[0084] Working principle:
[0085] The support frame 22 provides support for the overall electrode wire fixing device 2, so that its height is higher than the grinding wheel unit 32. After the electric gripper 21 fixes the electrode wire 6, the motor 23 is started by the external power supply, so that the rotating base 24 drives the electrode wire 6 to rotate at high speed.
[0086] in,
[0087] ①In actual use, the motor selected for motor 23 has a speed of 1000 rpm;
[0088] ② The electric gripper 21 is made of rubber to prevent damage to the insulation layer on the surface of the electrode wire during the gripper clamping and rotation process. The electric gripper 21 and the rotating base 24 can be fixed with bolts for easy replacement or maintenance later.

[0105] As described above, the structure of the grinding wheel unit 32 includes:
[0106] A cover 321 is mounted on the grinding base plate 311;
[0107] The knob shaft 324 is located above the output shaft of the grinding rotary motor 4, and its rear half is provided with a forward threaded section A, a threadless section B and a reverse threaded section C in sequence. The knob shaft 324 is provided with a rotary knob 323 on the cover 321 through the bearing 322.
[0108] The support arm 325 is provided with a threaded through hole, and is bolted to the knob shaft 324 through the through hole. Two sets of the support arms 325 are symmetrically arranged about the unthreaded section B of the knob shaft 324. A fixing block 3251 is provided protruding from the side of the support arm 325.

[0111] Working principle:
[0112] The specific method for adjusting the wedge gap 51 between the two grinding wheels 5 using the grinding wheel unit 32 is as follows:
[0113] When the operator turns the rotary knob 323, it drives the knob shaft 324 to rotate. Since the two sets of support arms 325 are respectively threaded onto the forward-rotating thread section A and the reverse-rotating thread section C, the knob shaft 324 rotates, and the two support arms 325 move accordingly. Since the threads rotate in opposite directions, the two support arms 325 move in opposite directions, thereby realizing the distance adjustment of the two grinding wheels 5, which in turn drives the grinding wheel rotation shaft 326 on the fixed block 3251 to move towards each other, so as to meet the sharpening requirements of electrode wires of different diameters.
