Description

Technical Field

[0001] This invention relates to the field of circuit board milling technology, and in particular to a microchannel milling device. Background Technology

[0002] When processing microchannels on circuit boards, a fine milling device is required. The edges of the microchannels on the circuit board converge radially, which cannot be milled with a rotary milling cutter. Therefore, vertical milling cutters are commonly used for grooving. However, vertical milling cutters are slow and prone to damage and breakage, resulting in higher costs.

[0003] The milling equipment currently in use has the following disadvantages: 1. Using a single milling method results in slow milling efficiency, high consumption costs, and a lack of combined all-around milling functions, leading to long processing times for each operation; 2. It lacks the function of automatic positioning and unlocking, making it inconvenient to automatically position the circuit board according to its shape; 3.

If the microchannels are not properly milled, they will block the movement of the combing needles. The combing needles will transmit pressure to the control frame, which will then feed back to the pressure sensor and the verification program to issue an alarm. Attached Figure Description

[0025] The bottom of the material support 6 is fixedly equipped with a main control piston 604, the telescopic end of the main control piston 604 faces backward, and a U-shaped frame 605 is fixedly installed at the telescopic end of the main control piston 604; a pipeline is provided between the main control piston 604 and the positioning piston 602, and a one-way valve 606 and a push-button valve 607 are also connected in the pipeline, and the one-way valve 606 and the push-button valve 607 are connected to different branches in the pipeline; when the button below the push-button valve 607 contacts the trigger 101, it retracts and triggers the push-button valve 607. The push-button valve 607 is a self-locking button, which closes when pressed once and opens when pressed again.

[0026] Hydraulic oil is filled between the positioning piston 602 and the main control piston 604. When the main control piston 604 retracts, the positioning piston 602 extends. Springs for extending the positioning piston 602 are provided inside each positioning piston 602.

[0027] Among them, a trigger baffle 7 is fixedly installed at the front end of the main outdoor unit 1, and two sets of trigger rods 701 are fixedly installed on the rear side of the trigger baffle 7. The trigger rods 701 can contact the U-shaped frame 605.

[0028] Among them, a pressure sensor 803 is fixedly installed in the lifting rod 802, and the pressure sensor 803 contacts the control frame 9; two sets of guide rods 804 are fixedly installed on the top of the lifting rod 802, and the guide rods 804 are slidably connected to the connecting plate 8.

[0029] like Figure 1-7 As shown, starting the horizontal axis motor 202 drives the horizontal axis lead screw 201 to rotate, which can control the horizontal movement of the horizontal moving seat 3. The first longitudinal axis motor 302 drives the first longitudinal axis lead screw 301 to rotate, and the first longitudinal axis lead screw 301 can drive the L-shaped frame 5 to move back and forth. The second longitudinal axis motor 304 drives the second longitudinal axis lead screw 303 to rotate, and the second longitudinal axis lead screw 303 can drive the main milling machine 4 to move back and forth. The control program is set so that during milling, the electric cylinder A401 is used to lower the rotary milling head 402, and the rotary milling motor 403 drives the rotary milling head 402 to work. Then the main milling head 4 is moved to perform longitudinal grooving. After completing the longitudinal slotting, reset the position of the main milling machine 4, start the electric cylinder B501 to lower the vertical milling motor 503 and the vertical milling machine 504, and then perform milling on the curved path. By combining the two milling methods in sequence, automated milling can be achieved.

[0030] Example 2: Based on Example 1, such as Figure 8 As shown, the unprocessed circuit board is placed on top of the work support 601, and then the forward and backward motor 102 is started to drive the forward and backward screw 103 to rotate, and the material support 6 is moved backward through the thread transmission. During this process, the button valve 607 contacts the trigger 101 and automatically closes. The positioning piston 602 extends naturally through the internal spring, and the hydraulic oil in the main control piston 604 is drawn out, causing the main control piston 604 to retract. The hydraulic oil in the main control piston 604 passes through the one-way valve 606 and enters the positioning piston 602, which adaptively locks the circuit board. Conversely, when disassembling the circuit board, the reverse forward and backward motor 102 moves the material support 6 forward. During this process, the button valve 607 contacts the trigger 101 and automatically opens. The material support 6 continues to move forward, and the trigger rod 701 contacts the U-shaped frame 605 to open the main control piston 604. The main control piston 604 extends and generates negative pressure, which fully retracts the positioning piston 602. The hydraulic oil in the positioning piston 602 passes through the button valve 607 and enters the positioning piston 602 to complete the unlocking.

[0031] Example 3: Based on Example 1, such as Figure 9 As shown, before the circuit board moves forward, the electric cylinder C801 is activated to lower the lifting rod 802. The control frame 9 lowers synchronously to align the combing needles 903 with the microchannels of the circuit board. Then, the material support 6 moves forward, and the combing needles 903 enter the front microchannel. As the microchannels diffuse, the combing needles 903 automatically separate to achieve adaptation. If there is milling slag in the microchannel, it will be removed. If the microchannel is not properly milled, it will block the movement of the combing needles 903. The combing needles 903 transmit pressure to the control frame 9, which then feeds back to the pressure sensor 803. The feedback is sent to the verification program to issue a warning and raise the control frame 9, allowing the circuit board to move forward.

[0032] The specific usage and function of this embodiment: In this invention, as shown in the example... Figure 1 In this state, the unprocessed circuit board is placed above the work support 601, and then the forward and backward motor 102 is started to drive the forward and backward screw 103 to rotate, and the material support 6 is moved backward through the thread transmission. During this period, the button valve 607 contacts the trigger 101 and automatically closes. The positioning piston 602 extends naturally through the internal spring, and the hydraulic oil in the main control piston 604 is drawn out, causing the main control piston 604 to retract. The hydraulic oil in the main control piston 604 passes through the one-way valve 606 and enters the positioning piston 602, which adaptively locks the circuit board. Conversely, when disassembling the circuit board, the reverse forward and backward motor 102 moves the material support 6 forward. During this process, the button valve 607 contacts the trigger 101 and automatically opens. The material support 6 continues to move forward, and the trigger rod 701 contacts the U-shaped frame 605 to open the main control piston 604. The main control piston 604 extends and generates negative pressure, which fully retracts the positioning piston 602. The hydraulic oil in the positioning piston 602 passes through the button valve 607 and enters the positioning piston 602 to complete the unlocking. The horizontal axis motor 202 is started to drive the horizontal axis lead screw 201 to rotate, which can control the horizontal movement of the transverse slide 3; the first vertical axis motor 302 drives the first vertical axis lead screw 301 to rotate, which can drive the L-shaped frame 5 to move back and forth; the second vertical axis motor 304 drives the second vertical axis lead screw 303 to rotate, which can drive the main milling machine 4 to move back and forth. The control program is set so that during milling, the electric cylinder A401 lowers the rotary milling head 402, and the rotary milling motor 403 drives the rotary milling head 402 to work. Then the main milling head 4 is moved to perform longitudinal grooving. After the longitudinal grooving is completed, the position of the main milling head 4 is reset, and the electric cylinder B501 is started to lower the vertical milling motor 503 and the vertical milling head 504 to perform milling on curved paths. By combining the two milling methods in sequence, automated milling can be achieved. Before the circuit board moves forward, the electric cylinder C801 is activated to lower the lifting rod 802. The control frame 9 lowers synchronously to align the combing needles 903 with the microchannels of the circuit board. Then, the material support 6 moves forward, and the combing needles 903 enter the front microchannel. As the microchannels diffuse, the combing needles 903 automatically separate to achieve adaptation. If there is milling slag in the microchannel, it will be removed. If the microchannel is not properly milled, it will block the movement of the combing needles 903. The combing needles 903 transmit pressure to the control frame 9, which then feeds back to the pressure sensor 803. The feedback is sent to the verification program to issue a warning and raise the control frame 9, allowing the circuit board to move forward. If the combing needles 903 pass smoothly through the microchannel, the dispersed combing needles 903 and the horizontal slider 902 will automatically reset by the spring outside the horizontal bar 901. The milling work can be completed by replacing the circuit board and sweeping away the milling slag.
