Description

Technical Field

[0001] The present invention relates to the technical field of carbon brush production, and specifically to a production method for a full-automatic production line for carbon brush products. Background Art

[0002] A carbon brush, also called a brush, is a sliding contact part and is widely used in many electrical equipment. The main materials used in the product of the carbon brush are graphite and impregnated graphite. The carbon brush is a device for transmitting energy or signals between the fixed part and the rotating part of a motor, a generator or other rotating machinery. It is generally made of pure carbon plus a solidifying agent.

[0003] In the process of production and preparation of carbon brushes, a large number of devices are used. The devices are large in volume, low in integration, and high in space occupancy rate. Moreover, after the carbon brush is sintered and formed, the cooling speed is slow, and an oxide layer is easily formed at high temperatures. If not cleaned, it will affect the performance of the carbon brush. At the same time, the residues and particles overflowing during the sintering process cause the surface of the carbon brush to be uneven, affecting subsequent processing. In addition, during the feeding process of the carbon brush, a vibrating feeding tray is required. The existing vibrating feeding tray is difficult to ensure that the directions of the fed carbon brushes are consistent and is prone to blockage, reducing the feeding speed. At the same time, during the production process of the carbon brush, the surface needs to be ground. The existing manual grinding method has low efficiency, slow speed, and low precision, and it is difficult to ensure the grinding accuracy of the carbon brush. Summary of the Invention

[0037] Please refer to Figure 11 , an embodiment provided by the present invention: a production method of a full-automatic production line for carbon brush products, including Step 1, carbon brush molding; Step 2, carbon brush sintering; Step 3, surface cleaning; Step 4, vibrating feeding; Step 5, four-sided grinding; Step 6, processing.

[0038] In the above Step 1, first, weigh carbon powder, copper powder and other chemicals according to the formula of the carbon brush, then fully mix the raw materials evenly, then put the raw materials into the hopper of the carbon brush molding machine 8, and then turn on the carbon brush molding machine 8. The filling mechanism of the carbon brush molding machine 8 automatically adds the powder into the mold cavity, and the punch of the carbon brush molding machine 8 presses down to press the carbon brush in the mold into a carbon block with a certain strength and density for standby;

[0039] In the above Step 2, after the carbon block is pressed and formed in Step 1, put it into the tray, and then put the tray into the high-temperature electric furnace 7 for high-temperature sintering. The sintering temperature is 900-1200 °C and the time is 2-3 h. After sintering, take it out for standby;

[0040] In the above Step 3, after the carbon brush is sintered in Step 2, place the carbon brush together with the tray on the conveyor belt 602 of the dust blowing and removing mechanism 6 for gas blowing, cooling and temperature reduction, and remove the dust on the surface. At the same time, use the cleaning roller 611 to remove the impurities and dust on the surface, and then set it aside for standby;

[0041] In the above Step 4, after the air blowing, dust removing and cooling in Step 3 are completed, put the carbon brush into the vibrating feeding mechanism 5 for automatic feeding to ensure that the feeding direction is consistent, and ensure that the carbon brush enters the four-sided grinding mechanism 2 in the same direction;

[0042] In the above Step 5, when the carbon brush in Step 3 is fed into the four-sided grinding mechanism 2 through the vibrating feeding mechanism 5, use the four-sided grinding mechanism 2 to grind the four sides of the carbon brush to ensure that the size is qualified, and then set it aside for standby;

[0043] In the above Step 6, after the four-sided grinding in Step 5 is completed, drill holes, plant leads and apply glue to the carbon brush to complete the production of the carbon brush.

[0044] Based on the above, the advantages of the present invention are as follows. When the present invention is in use and cooling and dust removal are required, the carbon brush after being formed by the carbon brush forming machine 8 and sintered in the high-temperature electric furnace 7 is taken out and placed on the conveyor belt 602 at the top of the fixed base 601. At this time, the first servo motor 612 is turned on, and the output end of the first servo motor 612 drives the conveyor belt 602 to convey forward, and then drives the carbon brush to move directly below the gantry 608. At this time, the air pump 613 is turned on, and the air pump 613 conveys cold air through the air delivery pipe 610 into the flow dividing plate 609 for flow division. The air after flow division is ejected through the nozzle 607, which is convenient for quickly cooling the carbon brush, reducing the oxidation of the carbon brush. Subsequently, after cooling, the conveyor belt 602 drives the carbon brush to convey forward. At this time, the lifting cylinder 604 is turned on, the output end of the lifting cylinder 604 descends, immediately drives the fixed angle iron 605 to descend, and then drives the cleaning roller 611 to descend. At this time, the drive motor 606 is turned on, and the output end of the drive motor 606 drives the cleaning roller 611 to rotate, using the cleaning roller 611 to clean the surface of the carbon brush, avoiding the influence of impurities and particles overflowing from the surface on subsequent processing;

[0045] When using the vibrating feeding mechanism 5 for feeding, the vibrating feeder main body 501 conveys the carbon brush spirally upward. When the carbon brush moves to one side of the material leakage hole 506, the guide wheel 507 is used for guiding and blocking. The carbon brushes with the same direction enter the feeding track 502 through the guide wheel 507, and are conveyed and fed by the conveying chain 503. The carbon brushes with inconsistent directions are blocked by the guide wheel 507 and fall into the material leakage hole 506, and return to the vibrating feeder main body 501 for re-feeding. This effectively ensures the consistency of the feeding direction of the carbon brush. At the same time, the guide wheel 507 itself can rotate, and with the setting of the material leakage hole 506, the situation of carbon brush blockage is reduced, and the feeding efficiency is improved. The fixed head 504 and the mounting rod 505 are used to fix the guide wheel 507;

[0046] After the material is loaded through the vibrating loading mechanism 5, it is transported to the first grinding cylinder 201 in the four-sided grinding mechanism 2 through the loading track 502. At this time, the second servo motor 216 is turned on, and the output end of the second servo motor 216 starts to rotate, which immediately drives the first driving shaft 214 to rotate, and then drives the second transmission wheel 212 to rotate, and at the same time drives the first driving sprocket 213 to rotate, and then drives the first chain 202 to rotate, and the first chain 202 drives the first driven sprocket 203 to rotate, and then drives the second driven shaft 211 to rotate, and then drives the remaining second transmission wheels 212 to rotate, and the rotation of the second transmission wheel 212 drives the carbon brush to be transported forward along the first grinding cylinder 201, and then the grinding stone inside the first grinding cylinder 201 hits the top of the carbon brush. The first gear 204 is driven by the second gear 206 to grind the top and bottom surfaces of the carbon brush. After completion, the carbon brush continues to be transported to the second grinding cylinder 206. At this time, the third servo motor 217 is turned on. The third servo motor 217 drives the second driving shaft 219 to rotate, and then drives the second driving sprocket 218 to rotate, and then drives the second chain 208 to rotate, and then drives the second driven sprocket 209 to rotate, thereby driving the first driven shaft 210 to rotate, and then drives the first transmission wheel 204 to rotate. The carbon brush is transported forward by the first transmission wheel 204, and the grinding stones inside the second grinding cylinder 206 are used to grind the two sides of the carbon brush. After completion, it is taken out, thereby realizing automatic grinding of the four sides of the carbon brush, reducing manual participation, and improving work efficiency. The support rod 207 is used to support the first grinding cylinder 201 and the second grinding cylinder 206.
