Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and in particular to a circuit board transfer mechanism and a use method thereof. Background Art

[0002] A circuit board is an insulating board with connecting conductors, on which electronic components are fixed and connected to form a circuit. The circuit boards widely used in industry are mostly flexible printed circuit boards (FPC), rigid printed circuit boards (PCB), and flexible and rigid combined printed circuit boards (FPCB). Their common feature is that they are all flat boards, and the circuits are set on the flat substrate by printing, etching, etc. The advantages of flat circuit boards are high line density and thinness.

[0003] During the existing circuit board manufacturing process, when transferring the circuit, the copper plate must first be positioned using a clamp, and then the transfer paper must be completely attached to the copper plate, and then a hot pressing device must be used to press the transfer paper to achieve the transfer of the circuit pattern. However, during the specific operation process, the staff has to operate the clamp in cumbersome steps, and the clamp cannot be effectively and automatically adapted to the clamping and positioning of copper plates of different sizes, resulting in low circuit board processing efficiency. At the same time, the existing pressing transfer method is to transfer from top to bottom. During this process, bubbles are easily generated between the transfer paper and the copper plate, which makes the transfer paper prone to wrinkles during pressing, resulting in distortion or loss of the transferred circuit pattern, thereby reducing the processing quality of the circuit board.

[0019] The present invention also discloses a method for using the circuit board transfer mechanism, comprising the following steps:

[0020] S1: When performing circuit transfer, the staff lifts up the first elastic telescopic rod and the second elastic telescopic rod to move the first hot pressing plate and the second hot pressing plate upwards, and then the staff tilts the copper plate down between the fixed clamp seat and the movable clamp seat, and one side of the copper plate first abuts against the vertical plate of the movable clamp seat, and the movable clamp seat is forced to squeeze the elastic telescopic tube, and the clamping distance between the movable clamp seat and the fixed clamp seat automatically adapts to the size of the copper plate, and then the other end of the copper plate is lowered to the fixed clamp seat, so that the copper plate is finally horizontally attached to the base;

[0021] S2: Then the staff aligns the transfer paper with the toner circuit on the surface and places it on the copper plate. The staff no longer lifts the first elastic telescopic rod and the second elastic telescopic rod. The first elastic telescopic rod and the second elastic telescopic rod respectively push the first hot pressing plate and the second hot pressing plate to move downward. The first hot pressing plate and the second hot pressing plate press down and position the end of the transfer paper close to the movable clamping seat.

[0022] S3: Control the electric heating elements in the first hot pressing plate and the second hot pressing plate to work, and then control the electric push rod to operate. The electric push rod stretches and presses the entire moving frame downward through the movable block. The moving frame drives the slider to slide in the slide slot through the connecting rod. The moving frame moves vertically downward to compress the first elastic telescopic rod and the second elastic telescopic rod, so that the first hot pressing plate and the second hot pressing plate are tightly pressed against the transfer paper, and the toner circuit on the transfer paper is transferred to the copper plate;

[0023] When the movable frame moves downward vertically, the limit plate is pressed downward by the pressure rod. When the limit plate is forced to move downward, the movable plate is driven downward by the third elastic telescopic rod, so that the positioning plug rod at the bottom of the movable plate is inserted into the positioning plug hole of the inner rod, limiting the expansion and contraction of the elastic telescopic tube, and maintaining the stability of the movable clamp seat and the fixed clamp seat in clamping and positioning the copper plate;

[0024] S4: As the electric push rod continues to operate, the telescopic end of the electric push rod drives the movable block to move horizontally in the movable frame, and the movable block drives the second hot pressing plate to separate from the first hot pressing plate through the second elastic telescopic rod, and the second hot pressing plate moves from the side close to the movable clamp seat to the fixed clamp seat, so that the second hot pressing plate heat-presses the transfer paper from one end to the other end, rather than pressing the transfer paper down on the copper plate as a whole from top to bottom;

[0025] When the movable block moves laterally in the movable groove, it squeezes the pneumatic telescopic part, and the piston squeezes the air in the sleeve. The air in the sleeve enters the exhaust pipe through the air guide pipe, and the exhaust pipe blows the upwardly inclined exhaust port onto the transfer paper that is being hot-pressed, so that the transfer paper does not come into contact with the copper plate before hot-pressing, so that the second hot-pressing plate hot-presses the transfer paper onto the copper plate from left to right.

[0026] Compared with the prior art, the present invention provides a circuit board transfer mechanism and a method of using the same, which have the following beneficial effects:

[0027] 1. The circuit board transfer mechanism and the use method thereof drive the pressure rod to move downward when the pushing mechanism is working, so that the pressure rod cooperates with the self-locking component to lock the elastic telescopic tube, which is convenient for quickly automatically locking and limiting the clamping state of the copper plate, without the need for tedious operations by the staff, and is suitable for clamping copper plates of different sizes, with strong applicability, thereby improving the efficiency of circuit board transfer processing.

[0028] 2. The circuit board transfer mechanism and its use method work by cooperating with the hot-pressing transfer assembly through the pushing mechanism, so that the hot-pressing transfer assembly moves from one end of the copper plate to the other end, and then the transfer paper is gradually hot-pressed and attached to the copper plate, replacing the hot-pressing transfer method of pressing the transfer paper down on the copper plate from top to bottom as a whole, avoiding the distortion or loss of the transferred circuit pattern due to bubbles between the transfer paper and the copper plate, thereby ensuring the processing quality of the circuit board.

[0029] 3. The circuit board transfer mechanism and the method of using the same, wherein the movable block squeezes the pneumatic telescopic part when it moves horizontally in the movable groove, and the piston squeezes the air in the sleeve. The air in the sleeve enters the exhaust pipe through the air guide pipe, and the exhaust pipe blows the transfer paper that is being hot-pressed at this time through the upwardly inclined exhaust port, so that the transfer paper does not contact with the copper plate before hot-pressing, so that the second hot-pressing plate hot-presses the transfer paper on the copper plate from left to right in sequence, avoiding bubbles due to the bonding between the transfer paper and the copper plate before hot-pressing, which causes the circuit pattern to be distorted or missing during the subsequent hot-pressing transfer of the transfer paper, thereby reducing the probability of misalignment of the transfer pattern and ensuring the processing quality of the circuit board.

[0052] Furthermore, the hot pressing transfer assembly includes a first elastic telescopic rod 8 fixedly mounted at the bottom of a movable frame 702, a first hot pressing plate 801 fixedly mounted at the bottom of the first elastic telescopic rod 8, a movable groove 7021 is opened on the movable frame 702, a movable block 7022 is slidably connected in the movable groove 7021, a pneumatic telescopic member 10 is arranged between the movable block 7022 and the inner wall of the movable groove 7021, a second elastic telescopic rod 9 is fixedly mounted at the bottom of the movable block 7022, a second hot pressing plate 901 is connected to the bottom of the second elastic telescopic rod 9, and electric heating elements are arranged in both the first hot pressing plate 801 and the second hot pressing plate 901.

[0053] Furthermore, a side of the first hot pressing plate 801 away from the second hot pressing plate 901 and a side of the vertical plate 202 away from the material guide plate 203 are in the same vertical plane.

[0054] Specifically, when performing circuit transfer, the staff lifts the first elastic telescopic rod 8 and the second elastic telescopic rod 9 to move the first hot pressing plate 801 and the second hot pressing plate 901 upwards, and then the staff tilts the copper plate 4 down to between the fixed clamp seat 2 and the movable clamp seat 3, and one side of the copper plate 4 first abuts against the vertical plate 202 of the movable clamp seat 3, and the movable clamp seat 3 is forced to squeeze the elastic telescopic tube 5, and the clamping distance between the movable clamp seat 3 and the fixed clamp seat 2 automatically adapts to the size of the copper plate 4, and then the other end of the copper plate 4 is lowered to the fixed clamp seat 2, so that the copper plate 4 is finally horizontally fitted.

The second hot pressing plate 901 moves from the side close to the movable clamping seat 3 to the fixed clamping seat 2, so that the second hot pressing plate 901 hot-presses the transfer paper 401 from one end to the other end, rather than pressing the transfer paper 401 down on the copper plate 4 from top to bottom as a whole, thereby avoiding distortion or loss of the transferred circuit pattern due to bubbles between the transfer paper 401 and the copper plate 4, thereby ensuring the processing quality of the circuit board.

[0055] Example 3: Reference Figure 1 , Figure 2 , Figure 8 and Fig. 9 , a circuit board transfer mechanism, based on Example 2, further, the elastic telescopic tube 5 includes an outer tube 501 fixedly connected to the movable clamping seat 3, an inner rod 502 slidably connected in the outer tube 501 and connected to the support plate 101, and a first elastic element 503 arranged between the inner wall of the outer tube 501 and the inner rod 502, and the first elastic element 503 is set as a spring.

[0058] Specifically, when the pushing mechanism is working, the electric push rod 701 is stretched and presses down the entire movable frame 702 through the movable block 7022. When the movable frame 702 moves vertically downward, the limit plate 112 is pressed down by the pressure rod 6. When the limit plate 112 is forced to move downward, the movable plate 114 is driven to move downward through the third elastic telescopic rod 111, so that the positioning rod 115 at the bottom of the movable plate 114 is inserted into the positioning hole 5021 of the inner rod 502, limiting the expansion and contraction of the elastic telescopic tube 5, maintaining the stability of the clamping and positioning of the copper plate 4 by the movable clamp seat 3 and the fixed clamp seat 2, and avoiding the loosening of the copper plate 4 during transfer and affecting the transfer effect; it should be noted that the positioning rods 115 are multiple and unequally spaced, so that there is always at least one positioning rod 115 aligned and matched with the positioning hole 5021 of the inner rod 502, to ensure the positioning effect of the elastic telescopic tube 5.

[0060] Specifically, when the pushing mechanism is working, the telescopic end of the electric push rod 701 drives the movable block 7022 to move horizontally in the movable frame 702, and the movable block 7022 drives the second hot pressing plate 901 to separate from the first hot pressing plate 801 through the second elastic telescopic rod 9, and the second hot pressing plate 901 moves from the side close to the movable clamping seat 3 to the fixed clamping seat 2, so that the second hot pressing plate 901 heat-presses the transfer paper 401 from one end to the other end, rather than pressing the transfer paper 401 down on the copper plate 4 from top to bottom as a whole. When the movable block 7022 moves horizontally in the movable groove 7021, it squeezes the pneumatic telescopic member 10, and the piston 1002 is sleeved. The air in the tube 1001 is squeezed, and the air in the sleeve 1001 enters the exhaust pipe 121 through the air guide pipe 12. The exhaust port of the exhaust pipe 121 tilted upward blows the transfer paper 401 which is being hot-pressed at this time, so that the transfer paper 401 does not contact with the copper plate 4 before hot-pressing, so that the second hot-pressing plate 901 hot-presses the transfer paper 401 on the copper plate 4 from left to right in sequence, avoiding bubbles due to the lamination between the transfer paper 401 and the copper plate 4 before hot-pressing, resulting in distortion or loss of the circuit pattern during subsequent hot-pressing transfer of the transfer paper 401, reducing the probability of misalignment of the transfer pattern, and ensuring the processing quality of the circuit board.

[0061] The present invention also discloses a method for using the circuit board transfer mechanism, comprising the following steps:

[0062] S1: When performing circuit transfer, the staff lifts up the first elastic telescopic rod 8 and the second elastic telescopic rod 9 to move the first hot pressing plate 801 and the second hot pressing plate 901 upwards, and then the staff tilts the copper plate 4 down between the fixed clamp seat 2 and the movable clamp seat 3, and one side of the copper plate 4 first abuts against the vertical plate 202 of the movable clamp seat 3, and the movable clamp seat 3 is forced to squeeze the elastic telescopic tube 5, and the clamping distance between the movable clamp seat 3 and the fixed clamp seat 2 automatically adapts to the size of the copper plate 4, and then the other end of the copper plate 4 is lowered to the fixed clamp seat 2, so that the copper plate 4 is finally horizontally attached to the base 1;

[0063] S2: Then the staff aligns the transfer paper 401 with the toner circuit on the surface and places it on the copper plate 4. The staff no longer lifts the first elastic telescopic rod 8 and the second elastic telescopic rod 9. The first elastic telescopic rod 8 and the second elastic telescopic rod 9 respectively push the first hot pressing plate 801 and the second hot pressing plate 901 to move downward. The first hot pressing plate 801 and the second hot pressing plate 901 press down and position the end of the transfer paper 401 close to the movable clamping seat 3.

[0064] S3: Control the electric heating elements in the first hot pressing plate 801 and the second hot pressing plate 901 to work, and then control the electric push rod 701 to operate. The electric push rod 701 stretches and presses the entire movable frame 702 downward through the movable block 7022. The movable frame 702 drives the slider 704 to slide in the slide groove 705 through the connecting rod 703. The movable frame 702 moves vertically downward to compress the first elastic telescopic rod 8 and the second elastic telescopic rod 9, so that the first hot pressing plate 801 and the second hot pressing plate 901 are tightly pressed against the transfer paper 401, and the toner circuit on the transfer paper 401 is transferred to the copper plate 4;

[0065] When the movable frame 702 moves downward vertically, the limit plate 112 is pressed downward by the pressure rod 6. When the limit plate 112 is forced to move downward, the movable plate 114 is driven downward by the third elastic telescopic rod 111, so that the positioning rod 115 at the bottom of the movable plate 114 is inserted into the positioning socket 5021 of the inner rod 502, limiting the expansion and contraction of the elastic telescopic tube 5, and maintaining the stability of the clamping and positioning of the copper plate 4 by the movable clamp seat 3 and the fixed clamp seat 2;

[0066] S4: As the electric push rod 701 continues to operate, the telescopic end of the electric push rod 701 drives the movable block 7022 to move horizontally in the movable frame 702, and the movable block 7022 drives the second hot pressing plate 901 to separate from the first hot pressing plate 801 through the second elastic telescopic rod 9, and the second hot pressing plate 901 moves from the side close to the movable clamping seat 3 to the fixed clamping seat 2, so that the second hot pressing plate 901 heat-presses the transfer paper 401 from one end to the other end, rather than pressing the transfer paper 401 down on the copper plate 4 as a whole from top to bottom;

[0067] When the movable block 7022 moves laterally in the movable groove 7021, it squeezes the pneumatic telescopic part 10, and the piston 1002 squeezes the air in the sleeve 1001. The air in the sleeve 1001 enters the exhaust pipe 121 through the air guide pipe 12, and the exhaust port of the exhaust pipe 121 tilted upward blows the transfer paper 401 that is being hot-pressed at this time, so that the transfer paper 401 does not come into contact with the copper plate 4 before hot-pressing, so that the second hot-pressing plate 901 hot-presses the transfer paper 401 onto the copper plate 4 from left to right.
