[0030] See Figure 1-7 As shown, a paper clamping and board placing device for circuit board production of the present invention includes a frame 1, an inner side of the frame 1 is provided with a loading station for placing a transfer vehicle loaded with paper clamped circuit boards, and a first lifting and adsorption component 2 for adsorbing spacer paper is provided at the loading station.

[0031] A roller conveyor 3 for discharging circuit boards is located on one side of the loading station. A horizontal platform 4 is mounted on the frame 1, moving between the loading station and above the roller conveyor 3. A second lifting and adsorption assembly 5 is located at the bottom of the horizontal platform 4, which is used to adsorb the circuit boards. When the horizontal platform 4 moves to the loading station, the first lifting and adsorption assembly 2 places the separator paper on the horizontal platform 4, while the second lifting and adsorption assembly 5 adsorbs the circuit boards. The horizontal platform includes guide rails, an electric push rod, and other components. Its specific structure is common knowledge to those skilled in the art and will not be described in detail here.

[0032] By setting a second lifting adsorption component at the bottom of the horizontal moving platform, the number of workstations is reduced to two through a double-layer synchronous moving structure. While the second lifting adsorption component adsorbs the circuit board, the first lifting adsorption component places the separator paper on the horizontal moving platform for temporary storage, making the overall structure of the board placement equipment more compact, which can effectively reduce the footprint and adapt to most workshop environments.

[0033] A stopper assembly 6 is provided on the horizontal movable platform 4 for placing the separator paper, and a flip discharge assembly 7 is provided on the frame 1 for discharging the separator paper. When the separator paper on the horizontal movable platform reaches a certain amount, it is discharged via the flip discharge assembly above the roller conveyor. The stopper assembly ensures that the separator paper lands in the corresponding position on the horizontal movable platform, preventing the separator paper from shifting during the movement of the horizontal movable platform and ensuring the subsequent output effect.

[0034] In this embodiment, the limiting assembly 6 preferably includes four limiting blocks 6a mounted on the horizontal movable platform 4. The four limiting blocks 6a respectively mate with the four edges of the separator paper. Guide wheels 6b are provided near the upper ends of both sides of each limiting block 6a. The four limiting blocks, projected onto the horizontal plane, form a rectangle that mates with the four edges of the separator paper. The length and width of the rectangle are slightly larger than the length and width of the separator paper by 0.5-2 cm, ensuring that the separator paper can smoothly enter between the limiting blocks.

[0035] When the separator paper falls from a height, the guide wheel guides the edge of the separator paper to prevent the edge of the separator paper from falling on the limit block and tilting, ensuring that the separator paper can be smoothly placed on the surface of the horizontal moving platform.

[0036] Further preferably, the horizontal movable platform 4 is provided with a guide slot 8, and the limit block 6a is engaged with the guide slot 8 by screws. The position of the limit block is adjusted by the guide slot so that the horizontal projection extension lines of the four limit blocks form rectangles of different sizes for limiting the placement of spacers of different sizes.

[0037] In this embodiment, the flipping and discharging assembly 7 preferably includes a flipping guide rail 7a disposed on the frame 1. The flipping guide rail 7a includes a vertical section 7b, with an outwardly inclined arc section 7c connected to the upper end of the vertical section 7b. The end of the flipping guide rail 7a is provided with a limit nut 7d. At least two spacers 7e are provided on the horizontal movable platform 4 for raising the separator paper and are parallel to the moving direction. A flipping suspension 7f is provided on the flipping guide rail 7a, and the front end of the flipping suspension 7f is adapted to the gap between adjacent spacers 7e. When the horizontal movable platform moves from the loading station to above the roller conveyor, the front end of the flipping suspension is inserted under the separator paper.

[0038] The height of the vertical section is not less than the height of the limit block. The flip suspension first rises along the vertical section to a height higher than the limit block and then flips to avoid the limit block interfering with the flip suspension or the separator supported by the flip suspension.

[0039] The front end of the flip suspension is provided with an inclined clearance surface to facilitate the insertion of the flip suspension into the gap supported by the gasket under the separator paper. At least three gaskets are provided on the horizontal movable platform on both sides and below the middle of the separator paper to prevent the middle of the separator paper from being concave and affecting the insertion of the flip suspension. The front end of the flip suspension is designed to be U-shaped to match the gap between the gaskets.

[0040] A cylinder 7g is hingedly connected to the frame 1, and a portal 7h is mounted on the tilting suspension 7f. The front end of the piston rod of the cylinder 7g is hinged above the portal 7h. Initially, the tilting suspension 7f is horizontal. When the tilting suspension 7f moves along the tilting guide 7a to the arc section 7c, the end of the tilting suspension 7f located outside the frame 1 tilts downward. The portal height is set according to the expected amount of spacer paper to be output. The portal height is greater than the stacking height of the spacer paper to ensure that the spacer paper can pass smoothly when it slides down the sliding frame.

[0041] A sliding frame 7j is mounted on the flip suspension 7f via a linear guide 7i. A vertical baffle 7k is located near the outer end of the sliding frame 7j. When the outer end of the flip suspension 7f tilts downward, the sliding frame 7j moves along the linear guide 7i to the outside of the frame 1. The sliding frame surface is higher than the flip suspension. When the flip suspension rotates to lift the paper stack, the paper stack is placed on the sliding frame surface, ensuring that the paper stack moves with the sliding frame when the sliding frame descends, rather than remaining on the flip suspension. The vertical baffle supports the paper stack after the flip suspension tilts and also serves as a reinforcing rib to increase the strength of the sliding frame.

[0042] The flip suspension is controlled by the contraction of the cylinder piston rod. When the flip suspension rises and rotates 5-10° along with the flip guide rail, the cylinder pauses. At this time, the slide frame slides down along the linear guide rail. When the slide frame slides down to the right position, the cylinder piston rod continues to contract and rotate the flip suspension, so that the slide frame moves to a height that is convenient for the operator to carry the separator paper.

[0043] At the same time, a corresponding damping unit can be provided on the linear guide rail to slow down the sliding speed of the sliding frame, so as to avoid the sliding frame colliding with the linear guide rail at too high a speed and causing damage.

[0044] In this embodiment, the frame 1 is preferably provided with a horizontal screw rod 9, which is provided with a movable articulated seat 10, and the cylinder 7g is hinged to the movable articulated seat 10. The horizontal screw rod is driven by a servo motor in conjunction with the cylinder. When the tilting suspension is in a horizontal position, the cylinder piston rod is extended and the movable articulated seat is located above the portal frame. When the cylinder piston rod is retracted, the movable articulated seat moves outward. When the tilting suspension is in a tilted position, the movable articulated seat is located outside the frame. This structure changes the force applied by the cylinder piston rod to the portal frame, preventing the tilting suspension from smoothly ascending due to incorrect force direction.

[0045] In this embodiment, a curved crank arm 11 is provided at the front end of the piston rod of the cylinder 7g. This curved crank arm 11 is hinged to the portal frame 7h; the curved surface of the curved crank arm 11 faces downward and outward from the frame 1. This curved crank arm redirects the pulling force of the cylinder piston rod, directing the pulling force outward when the tilting suspension reaches the arc section of the tilting guide rail, thereby improving the stability of the tilting suspension in its tilted state.

[0046] In this embodiment, the tilting suspension 7f preferably has a guide hole 12 that mates with the tilting guide rail 7a. This guide hole 12 comprises a semicircular portion that mates with the tilting guide rail 7a, with a rectangular portion integrally formed at the rear end of the semicircular portion. The inner wall of the guide hole 12 on one side of the rectangular portion is arc-shaped, and a fan-shaped ball bearing sleeve 13 is provided on the tilting guide rail 7a on the semicircular portion. With this structure, the arc-shaped inner wall of the guide hole is in line contact with the inner side of the tilting guide rail's arc segment, preventing the tilting suspension from getting stuck when rotating through the arc segment.

[0047] The ball sleeve is arranged on the side opposite to the cylinder. When the cylinder pulls the flip suspension, the ball sleeve plays a certain guiding role. At the same time, the ball sleeve contacts the flip guide rail through the ball, and the friction is small, so that the flip suspension can rise smoothly with the vertical section.

[0048] Furthermore, preferably, the sliding frame 7j is provided with stop plates 14 on either side, the inner surfaces of which are aligned with the inner surfaces of the stop assembly 6. An outwardly tilted guide plate 15 is provided at the front end of the stop plates 14. The stop plates prevent the interleaving paper from falling off the sides of the sliding frame during the tilting process, ensuring that the interleaving paper remains neatly arranged during output. The guide plates ensure that the two side stop plates can smoothly engage the interleaving paper when the sliding frame is inserted into the bottom of the interleaving paper along with the tilting suspension.

[0049] In this embodiment, the first lifting and adsorption assembly 2 includes a lifting unit 2a provided on a frame 1, a suction cup bracket 2b provided on the lifting unit 2a, and a plurality of first vacuum suction nozzles 2c distributed on both sides of the suction cup bracket 2b; a flapping cylinder 2d is provided on the end of the suction cup bracket 2b corresponding to the four vertices of the separator paper, and a second vacuum suction nozzle 2e is provided on the piston rod of each flapping cylinder 2d; when the first vacuum suction nozzle 2c adsorbs the separator paper, the second vacuum suction nozzle 2e performs reciprocating flapping on the four vertices of the separator paper. By reciprocatingly flapping the four vertices of the separator paper, the separator paper is prevented from adhering to the underlying circuit board due to factors such as static electricity, ensuring that the first vacuum suction nozzle only adsorbs the surface separator paper when the lifting unit rises.

[0050] The second lifting and adsorption assembly has the same structure as the first lifting and adsorption assembly, with the lifting unit located at the bottom of the horizontal moving platform. Similarly, the four vertices of the circuit board are reciprocated to avoid adhesion caused by factors such as static electricity.

[0051] During operation, the transfer cart loaded with paper-clamped circuit boards is pushed to the loading station and its first lifting and adsorption component is moved. The lifting unit descends to allow the first vacuum nozzle to adsorb the separator paper, while the second vacuum nozzle taps the four vertices of the separator paper back and forth, and then the lifting unit rises to take the separator paper out to the top.

[0052] The horizontal platform moves to the loading station, where the second lift suction assembly at the bottom absorbs the circuit board. Simultaneously, the first vacuum nozzle of the first lift suction assembly releases the separator paper, placing it on the horizontal platform for temporary storage. The horizontal platform moves above the roller conveyor, where the second lift suction assembly places the circuit board on the roller conveyor for unloading.

[0053] When the horizontal moving platform moves to the top of the roller conveyor, the flip suspension is inserted under the separator through the gap between the gaskets. If the separator on the horizontal moving platform reaches the predetermined amount or the working time reaches the predetermined time, the cylinder and the horizontal screw rod will cooperate to lift the flip suspension and rotate it outward to lift the separator and output it to the outside of the frame along with the sliding frame to be transported and output by the operator or external handling equipment.

[0054] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the technical field can, without departing from the scope of the technical features of the present invention, make partial changes or modifications to the technical contents disclosed in the present invention and make equivalent embodiments without departing from the technical features of the present invention. Such modifications still fall within the scope of the technical features of the present invention.
