1231247 V. Description of the invention (1) [Technical field to which the invention belongs] ^ The present invention "The sharp edges of the circuit board grinding and rounding machine boards are ground into rounds, which relates to a stepper. [Previous Technology] I During the manufacturing process of the conventional circuit board, the two manufacturers each need to grind them to rounded corners to prevent U 疋 from showing sharp angles; : Mostly; the rounded corners with tools or artificial squares are often not round enough and need to be improved. The wooden linear displacement, so the inventor of the grinding has taken this into consideration. Based on the cost case, I hope that the rounded corners can be ground by the road board. The equipment can self-request.

、 Professional and experience, special research and innovation, to improve the existing shortcomings, so as to make electricity and improve efficiency, in line with the factory [invention content] The present invention, "road board grinding fillet machine", its main purpose is to provide an automatic, high An efficient rounding machine for circuit boards, in particular, the ^ grinding mechanism is designed to have an arc-shaped movement function; in this way, the grinding mechanism can shift the fillet curve corresponding to the grinding, so as to make the circuit The running-in of the corners of the board is smooth, round, beautiful and fast. [Embodiment]

1231247 V. Description of the invention (2) I would like to clarify the “effects of electricity produced by the invention with the following drawings: First please refer to the first picture, road board grinding and filleting machine”, structure mechanism 2, shift mechanism 3, structure 6 Among them: the conveying mechanism 1 is linked by a motor 12 and the blocking mechanism 2 is provided with two specific rollers 1 1. When the blocking mechanism 2 moves the mechanism 3, it is arranged on 1 and the push plate 3 2, the cylinder 3 1 can be linked with the push plate 3 2 the clamping mechanism 4, the structural device 4 2; the grinding mechanism 5 is connected to the driving winding to the driven pulley 5 4 through the force shaft 51, and the cutter 5 5 makes The grinding mechanism 5 includes a sliding seat with a power cylinder 5 8 and a sliding seat 5 6 can be ground on the 5-way board of the base. Take a second picture to mainly squeeze and press several rollers of the mechanism. As a result, it was lost in the conveyor; when the gear was raised, the conveying mechanism was set higher than the drum 1 and included a motor (pulley 5, the driven cutter 5 5 seat 5 6 and the angle machine on the base 7). The best case and the third picture include: Conveying 4, Conveying by grinding machine 1 1 1 suitable stop mechanism 2 heights can exceed 1 side, higher than the side of the roller 1 for the upper pressing device (not shown in the figure) 2, equipped with a pulley 5 4 can have its rotation set at the bottom 5 7 The internal arc-shaped sliding structure constitutes an example. The structure 1 and 5 of this mechanism and its detailed statement "the unique rising roller 1 at each roller of the electric and blocking steering gear are driven by 11, the inner and outer 4 1 and the top. The function is set at the bottom of the belt 5; the seat 5 7 is configured to perform reciprocating movements in or out of the arc 1; the power displacement of the force cylinder 3; after pressing down the motor 3, there should be grinding and grinding the top, the way, the way;

Page 61231247 V. Description of the invention (3) The steering mechanism 6 is composed of a steering motor 60, an upper steering device 61, a lower steering device 62, and a jacking device 63, wherein the steering motor 60 can be linked. The upper steering device 61 is turned at an angle of ninety degrees. As for the lower steering device 62, it can be moved up or down by the jacking device 63, and can be used for clamping and steering with the upper steering device 61. With the above structure, referring to the fourth figure, the circuit board 9 is fed in by the conveying mechanism 1. At this time, the blocking mechanism 2 is in an ascending state, and the circuit board 9 can be blocked, and then the shift mechanism 3 can be operated to make Cause the push plate 3 2 to be moved out, and then touch the side of the circuit board 9 to push the circuit board 9 to the correct preset position (as shown in the fifth figure). 'Make the clamping mechanism 4 up and down to clamp the circuit board. 9 Steady clamping and fixing (as shown in the sixth figure); then make the grinding mechanism 2 act. As the π shift seat 5 6 can perform an arc position on the base 5 7, r r shift seat 5 6 the grinding tool 5 5 is also the arc cutting ζ road and line 7), with the grinding tool 5 5 has a rotating ^ = running-in function, please refer to the eighth and ninth pictures, the end angle of the circuit can be appropriately 9 1? Grinding rounded corners; after completing the rounding operation, ten pictures, the clamping mechanism 4 can be released from the upper and lower clamping, and the circuit board 9 can be placed on the wheel mechanism 1, at this time, the stop mechanism 2 has been lowered and moved. Relocation, the conveying mechanism i continuously feeds back the circuit board 9. When the motor i reaches the steering mechanism 6, it can be driven in time with the detection of the electric eye : J. Structure 6 is clamped M, that is, as in the eleventh figure, and then the steering motor = can turn the circuit board 9 to ninety degrees, as shown in the twelfth figure ^ steering mechanism 6 releases the home position (as shown in the thirteenth figure) ), Return the circuit J to the mechanism 1 again, and then use the conveying mechanism i to grind the end angle.

1231247 Figure); Continuity can be used to improve the practical road board grinding of the country. The application of this case is to explain the precise example. The embodiment does not use itb. 5. Description of the invention (4) The circuit board 9 is sent out as needed. Corner operations, the utilization value of the remaining corner industries. In summary, there are breakthrough achievements. This case has not accorded with the patent law and advancement. It should be granted as early as possible. Although the present invention is related to the details, but it can also be implemented by the skilled person. The scope of the patent is bounded. And in the rounding of the output, "the advantages of the electric step, the disclosure or disclosure requirements. Seek to encourage innovation according to the law. With the above, do not depart from the understanding of this issue. One of the previous disclosure, but it shall prevail The second circuit board 9 can also be used to turn the circuit board 9 at the end corners of the circuit board 9 to turn, so that the advancement meets the needs of the manufacturer and is rich in production of fillet machines. "Its technology is significantly improved, and it is not Easy to reach foreign literature and market, it is completely in line with novelty and practicability. I urge you to investigate and describe it, but you can still change the form and achieve it, and you will be familiar with it, and only borrow the principle of this case.
