[0002] The surfaces of traditional aluminum products are mostly frosted, AED, environmentally friendly paint or artificial leather, and there are no products with glossy brushed patterns. In high-tech products with multi-element appearances, brushed appearances are increasingly used. However, due to the different shapes and requirements of products with brushed appearances, the clamping tools will have a certain impact on the grinding angle of the grinding tools after clamping the processed products. Therefore, corresponding grinding tools need to be used for the clamping tools, and unique clamping tools need to be customized for each product. This leads to high production costs when producing different brushed products, resulting in an inability to meet the current market demand for products with brushed technology. Utility Model Content

[0020] The following combination Figures 1 to 3 The above method of the present application is further elaborated.
[0021] The present application provides an automatic wire drawing device, comprising a universal robot arm 1 and a tooling table 2, wherein the universal robot arm 1 has an automatic control system.
[0022] The Vientiane robotic arm is provided with a cylindrical grinding head 11 and a driving motor, and the driving shaft is drivingly connected to the motor;
[0023] The upper surface of the workbench 2 is provided with a plurality of rubber pads 22 , a plurality of air suction holes are arranged above the rubber pads 22 , and a channel 23 connecting the air suction holes is provided below the rubber pads, and the air suction holes are connected to the air suction pump 24 through the channel.
[0024] The universal robot arm 1 can process the product to be processed from various angles, and the surface of the product to be processed can be brushed through the cylindrical grinding head 11 thereon. The tooling table 2 is used to fix the product to be processed. The traditional tooling table 2 uses a clamping tool to clamp the product to be processed. The present application uses a rubber pad 22 to adsorb and fix the product to be processed, so that the surface that needs to be brushed can be fully presented, making it convenient for the universal robot arm 1 to polish the surface of the product to be processed in any direction. When the product to be processed is placed on the tooling table 2, the product to be processed is covered on the rubber pad 22. The suction holes provided on the rubber pad 22 generate negative pressure on the rubber pad 22 through the channel 23 and the suction pump 24 to fix the product to be processed, eliminating the need to use a clamping tool to fix the product to be processed. Moreover, the rubber pad 22 is not adsorbed once, but is continuously adsorbed by the suction pump 24, making the fixation of the product to be processed more stable. This solution uses a rubber pad 22 to adsorb the processed product on the tooling table 2, and cooperates with the universal robotic arm 1 to draw the surface of the processed product, preventing traditional clamping tools from limiting the angle of the grinding tool's drawing operation. In actual use, each tooling table 2 can be used for the drawing of a variety of processed products. When facing various types of processed products, it is only necessary to replace the tooling table 2 corresponding to the product very rarely, solving the problem of high production cost of the wire drawing process in the existing technology.
[0025] In some embodiments of the present application, the upper surface of the work table 2 has a protrusion, called a fixing protrusion 21, and the fixing protrusion 21 has a plane. The rubber pad 22 is arranged on the plane, and the edge of the disk of the rubber pad 22 is 0.2 mm to 0.5 mm higher than the plane.
[0026] A fixing protrusion 21 can be set on the tooling table 2 according to the shape of the product being processed, and a rubber pad 22 can be set on the plane of the fixing protrusion 21 according to actual needs. The adsorption of the rubber pad 22 should be relatively stable and enable the product being processed to fit well with the tooling table 2. The edge of the rubber pad 22 can be 0.2 mm to 0.5 mm higher than the plane. In actual use, the product being processed and the tooling table 2 are not completely fit together. If the edge of the rubber pad 22 is too low, it will affect the adhesion of the disk to the product being processed, resulting in air leakage during adsorption. If the edge of the rubber pad 22 is too high, it will cause the rubber pad 22 to lift the product being processed, resulting in unstable fixation, affecting the effect of the subsequent wire drawing process. After testing, it was found that raising the edge of the rubber pad 22 by 0.2 mm to 0.5 mm higher than the plane can prevent air leakage caused by incomplete adhesion and prevent the rubber pad 22 from lifting the product being processed, further stabilizing the fixation of the tooling table 2 to the product being processed, ensuring the wire drawing effect, improving the yield rate, and reducing production costs.
[0027] In some embodiments of the present application, the fixing protrusion 21 has an inclined side surface, and the angle between the inclined side surface and the upper surface of the tooling table 2 is between 45 degrees and 90 degrees.
[0028] The inclined side surface of the fixing protrusion 21 can be used to further strengthen the fixation of the tooling table 2 to the processed product. The angle between the inclined side surface and the upper surface of the tooling table 2 is between 45 degrees and 90 degrees. If the angle is too large, it will not have a fixing effect. If the angle is too small, it will affect the loading and unloading of the processed product on the tooling table 2, thereby reducing production efficiency. Therefore, setting the angle between 45 degrees and 90 degrees can further stabilize the fixation of the tooling table 2 to the processed product, ensure loading and unloading efficiency, and thus improve production efficiency.
[0029] In some embodiments of the present application, the edge of the rubber pad 22 is horizontally spaced from the edge of the plane by 0.3 mm to 0.5 mm.
[0030] The larger the adsorption area of the rubber pad 22, the more firmly the product being processed is fixed. However, in actual use, the cylindrical grinding head 11 needs to press against the plane of the product being processed with a certain force. When the edge of the rubber pad 22 is higher than the plane, the edge of the rubber pad 22 will protrude from the edge of the plane after the rubber pad 22 is adsorbed, resulting in unstable fixation of the product being processed. When the edge of the rubber pad 22 is lower than the plane or is on the same plane as the plane, the edge of the plane supporting the rubber pad 22 is too thin, and the cylindrical grinding head 11 is easily damaged when pressing against the plane of the product being processed, affecting the production progress. Setting the edge of the rubber pad 22 to be between 0.3 mm and 0.5 mm horizontally from the edge of the plane can not only ensure the maximum adsorption area, but also prevent the occurrence of the above-mentioned situation, further ensuring the effect of the process, preventing the reduction of yield and production efficiency due to damage to the tooling table 2, and further improving production efficiency.
[0031] In some embodiments of the present application, the distance between the plurality of rubber pads 22 is between 0.5 cm and 1 cm.
[0032] Under a certain working power of the suction pump 24, the more suction holes there are, the larger the suction area is, and the smaller the negative pressure value generated by each suction hole is. However, if the suction area is too small, the fixing effect of the processed product cannot be achieved. After many tests, it is found that setting the distance between the rubber pads 22 between 0.5 cm and 1 cm can balance the relationship between the suction area and the negative pressure value, so that the processed product will not be unstable due to excessive or small suction area. Therefore, setting the distance between the rubber pads 22 between 0.5 cm and 1 cm can avoid increasing the working power of the suction pump 24, and ensure the adsorption effect of the rubber pads 22 on the processed product under a certain power, prevent the yield from being reduced due to unstable fixation, and further improve production efficiency.
[0033] In some embodiments of the present application, a negative pressure detection sensor is provided in the channel 23 , and a signal output end of the negative pressure detection sensor is connected to a signal input end of the automatic control system.
[0034] The negative pressure detection sensor used in channel 23 can monitor in real time whether the processed product is firmly adsorbed, so as to facilitate the control system to judge whether the processed product is firmly fixed on the workbench 2. The judgment can be made by setting a threshold. If the negative pressure value output by the negative pressure detection sensor does not reach the threshold, it means that the adsorption is unstable and needs to be readjusted. The automatic control system controls the universal robot arm 1 to stop subsequent wire drawing processing, which can further ensure the yield rate, thereby further reducing production costs and improving production efficiency.
[0035] In some embodiments of the present application, the surface of the tooling table 2 is a curved surface.
[0036] A concave or convex surface can be set on the tooling table 2 according to the shape of the processed product, so that the processed workpiece can be embedded in the tooling table 2, further improving the firmness of the processed product fixed on the tooling table 2, thereby further preventing the decrease in yield rate due to unstable fixation, thereby further improving production efficiency and reducing production costs.
[0037] In some embodiments of the present application, the rubber pad has a depression around the suction hole to form a suction cup.
[0038] The rubber pad can be provided with a certain degree of depression around the suction hole as needed. When the suction pump is working, the rubber pad forms a suction cup to fix the processed product. This can further fix the processed product and prevent the processed product from moving in subsequent processes, further improve the yield rate and reduce production costs.
