Description

Technical Field

[0001] The present invention relates to a burr automatic removal device, and particularly to a process capable of removing burrs in a three-dimensional space of X, Y, and Z. Furthermore, by adjusting the wheelbase to increase the wheelbase according to a relatively large elastomer, full automation of the burr removal operation can be realized. Thereby, not only can manpower be surely saved, but also the processing efficiency can be effectively improved.

Background Art

[0002] The sealing ring of an O-ring is generally made of a synthetic rubber material, has the characteristic of a long service life, and is suitable for sealing. However, in the manufacturing process of the sealing ring of the O-ring, burrs are generated. Therefore, in order to maintain the sealing performance when mounting the sealing ring of the O-ring on a machine, it is further necessary to remove these burrs through a processing treatment.

[0003] Conventionally, burr processing using manpower requires time and energy, so it has low economic efficiency. Also, the burr removal operation mostly uses manpower and no automated burr removal process is performed, so the output of the production line cannot be improved. Therefore, the above processing method cannot meet the needs of manufacturers and users. Also, when removing burrs by manual processing, the accuracy cannot be grasped, so the quality of the sealing ring of the O-ring is not consistent, the defective rate is high, and the production cost is also high. At the same time, since the sharp knife of the trimming machine has a considerable danger, the operator must be careful to avoid injury during operation.

[0004] Therefore, at present, although the cooling and hardening treatment is utilized, the above-mentioned burr removal processing device generally uses high-cost liquid nitrogen as a coolant. Thus, not only is the processing cost high, but cooling using nitrogen can cause excessive hardening of the sealing ring of the O-ring, making it hard and brittle. Also, due to collisions, burrs may peel off, which has an adverse effect on the inherent elasticity of the sealing ring of the O-ring made of synthetic rubber. Therefore, the sealing ring of the O-ring is prone to problems of crack damage due to easy cooling and hardening.

[0005] Thus, the above-mentioned conventional sealing ring of the O-ring performs burr removal processing manually, which cannot meet the requirements of modern society with a lack of manpower and high salaries. Also, the subsequent burr removal processing device has problems such as the high cost of nitrogen and crack damage caused by easy excessive hardening due to cooling. Therefore, the above-mentioned burr processing problems and the disadvantages of the prior art must be solved.

[0006] In order to solve the above-mentioned drawbacks, the inventor of the present invention has carefully studied and utilized theory to effectively solve the above-mentioned drawbacks and proposes the present invention with a reasonable design.

[0040] According to the present invention, the automation arm 6 installs the elastomer 9 waiting for burr removal on the two assembly shafts 32. When the burr removal operation is performed by the human-machine interface 81, the two assembly shafts 32 attract the elastomer 9 waiting for burr removal in the X-axis direction to abut against it. Then, on the second axial guide 23, the assembly mechanism 3 is interlocked so that it approaches the blade rotation unit 4 in the Y-axis direction. The blade rotation unit 4 approaches the elastomer 9 waiting for burr removal in the Z-axis direction on the third axial guide 24 by the second movable block 241. Also, the assembly mechanism 41 is rotated forward and backward to drive the blade 43 so as to obtain an appropriate burr removal angle. The burr automatic removal device 100 according to the present invention can remove burrs from both the inner and outer edges of the elastomer 9 waiting for burr removal.
