Description

Technical Field

[0001] This utility model relates to the field of vacuum adsorption technology, specifically a circuit board transfer vacuum adsorption platform. Background Technology

[0002] Circuit boards are core components of electronic devices, consisting of an insulating substrate and conductive wiring layers. They are formed using precision etching processes to create predetermined circuit patterns, which are then used to connect and support electronic components. Circuit boards require a vacuum adsorption platform for transfer.

[0003] In the prior art, the authorized announcement number CN219107805U discloses a magnetically controlled PCB circuit board anti-leakage vacuum adsorption machine, which includes a robotic arm and a U-shaped plate, and a translational electromagnetic chuck structure is installed on the lower part of the U-shaped plate.

[0004] In the above solution, the suction cup can firmly hold the circuit board. Once the suction cup successfully holds the circuit board, a high-precision robotic arm can flexibly move the circuit board, thus smoothly transferring it between different workstations. However, in actual production, unforeseen situations may inevitably arise, such as various foreign objects accidentally landing on the surface of the circuit board. If these foreign objects happen to be located at the suction cup's adsorption position, they will directly affect the suction cup's adsorption effect, resulting in insufficient adsorption strength to support the weight of the circuit board, thus posing a significant safety hazard. In this case, the circuit board is very likely to fall due to weak adsorption, which will not only damage the circuit board itself but may also pose serious safety risks to production equipment and operators. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum adsorption platform for transferring circuit boards, in order to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circuit board transfer vacuum adsorption platform, comprising a main crossbeam, a secondary crossbeam fixedly mounted on the main crossbeam, vacuum suction cups fixedly mounted at both ends of the secondary crossbeam, an air extraction pipe connected to the vacuum suction cups, a solenoid valve provided on the air extraction pipe, a wiping mechanism mounted on the main crossbeam, the wiping mechanism comprising a first retaining sleeve fixedly mounted on the main crossbeam, a T-shaped crossbeam fixedly mounted on the first retaining sleeve, swing arms rotatably mounted at both ends of the T-shaped crossbeam, a movable shaft rotatably mounted at the end of the swing arm, a wiping roller rotatably mounted on the movable shaft, and a limiting mechanism installed between the wiping mechanisms, the limiting mechanism restricting the rotation of the swing arms.

[0007] Preferably, the wiping mechanism further includes mounting shafts installed at both ends of the T-shaped beam, and a torsion spring is sleeved on the mounting shaft, which provides torque to the mounting shaft.

[0008] Preferably, the wiping mechanism further includes mounting shafts installed at both ends of the T-shaped beam, and the mounting shafts are fitted with torsion springs, allowing them to rotate at both ends of the T-shaped beam.

[0009] Preferably, one end of the torsion spring is fixedly mounted on the mounting shaft, and the other end of the torsion spring is fixedly mounted on the T-shaped crossbeam. The T-shaped crossbeam is fixedly mounted on the main crossbeam through the first clamp. The swing arm is rotatably mounted on the T-shaped crossbeam through the mounting shaft. A bearing is installed at the end of the swing arm. The movable shaft is rotatably mounted on the swing arm through the bearing. The swing arm can drive the wiping roller to rotate.

[0010] Preferably, the limiting mechanism includes a second sleeve fixedly installed on the main crossbeam, a connecting seat fixedly installed at the bottom of the second sleeve, a cylinder fixedly installed on the connecting seat, a lifting crossbeam fixedly installed at the output end of the cylinder, a movable hole opened on the lifting crossbeam, a limiting rod rotatably installed in the movable hole, and the cylinder can drive the lifting crossbeam to move up and down.

[0011] Preferably, the connecting seat is connected with bolts, so that the cylinder is fixedly installed on the connecting seat by bolts.

[0012] Preferably, a bearing is installed in the movable hole, and the limiting rod is rotatably installed in the movable hole through the bearing, so that the limiting rod can restrict the movement of the swing arm.

[0013] Preferably, the cylinder is fixedly installed below the main crossbeam via a second clamp, and the lifting crossbeam is movably installed below the main crossbeam via the cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this application, the wiping roller can be moved downward by swinging the robotic arm. When it is blocked by the circuit board, the wiping roller will roll laterally along the surface of the circuit board and cause the swing arm to twist, thereby cleaning the adsorption area below the vacuum suction cup, so as to ensure the adsorption efficiency of the suction cup and reduce the possibility of the circuit board falling off.

[0016] 2. After the cleaning operation is completed in this application, the cylinder can be retracted. When the cylinder retracts, it will cause the lifting beam to move upward. When the lifting beam moves upward to a specific position, the limit rod will move below the swing arm in a torsional state, thereby restricting the rotational movement of the swing arm. After the swing arm rotation is restricted, the wiping roller cannot apply pressure to the circuit board, thus ensuring the stability of the adsorption intensity. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a circuit board transfer vacuum adsorption platform, including a main crossbeam 1, a secondary crossbeam 4 fixedly installed on the main crossbeam 1, vacuum suction cups 5 fixedly installed at both ends of the secondary crossbeam 4, an air extraction pipe 3 connected to the vacuum suction cups 5, an electromagnetic valve 2 provided on the air extraction pipe 3, a wiping mechanism 6 installed on the main crossbeam 1, and a limit mechanism 7 installed between the wiping mechanisms 6.

[0025] Specifically, the main beam 1 is securely mounted on the robotic arm, which, with its flexible movement, can effectively drive the entire device to perform precise movements. Through a carefully designed air extraction pipe 3, air is efficiently extracted from the vacuum suction cup 5, creating a negative pressure environment inside the suction cup, allowing it to firmly suck up and adhere to the circuit board. Furthermore, the close cooperation between the wiping mechanism 6 and the limiting mechanism 7 allows for wiping specific areas on the circuit board, ensuring the contact surface between the suction cup and the circuit board is clean and dust-free, thus significantly improving the suction effect.

[0026] Example 2:Figure 2 , Figure 3 and Figure 4 As shown, the wiping mechanism 6 includes a first retaining sleeve 601 fixedly installed on the main crossbeam 1, a T-shaped crossbeam 602 fixedly installed on the first retaining sleeve 601, a swing arm 603 rotatably installed at both ends of the T-shaped crossbeam 602, a movable shaft 605 rotatably installed at the end of the swing arm 603, and a wiping roller 604 rotatably installed on the movable shaft 605. The wiping mechanism 6 also includes a mounting shaft 606 installed at both ends of the T-shaped crossbeam 602, a torsion spring 607 sleeved on the mounting shaft 606, and mounting holes opened at both ends of the T-shaped crossbeam 602. The mounting shaft 606 is rotatably installed on the T-shaped crossbeam 602 through the mounting holes.

[0027] Specifically, the wiping roller 604 can be moved downwards along a preset path by controlling the robotic arm. When the wiping roller 604 contacts the circuit board, it will naturally roll laterally along the surface of the circuit board due to the obstruction of the circuit board. At the same time, the swing arm 603 twists, thereby achieving the purpose of thoroughly cleaning the adsorption area below the vacuum suction cup 5. This cleaning operation not only effectively ensures the adsorption effect of the suction cup, but also significantly reduces the risk of the circuit board falling off during the transfer process, ensuring the stability and safety of the entire production process. In addition, after the transfer is successfully completed, the torsion spring 607 will automatically activate, driving the swing arm 603 to rotate back to the initial position, so that the wiping roller 604 also returns to its initial state, preparing for the next cleaning operation.

[0028] Example 3: Figure 2 and Figure 5 As shown, the limiting mechanism 7 includes a second sleeve 701 fixedly installed on the main crossbeam 1. A connecting seat 702 is fixedly installed at the bottom of the second sleeve 701. A cylinder 703 is fixedly installed on the connecting seat 702. A lifting crossbeam 704 is fixedly installed at the output end of the cylinder 703. A movable hole 705 is opened on the lifting crossbeam 704. A limiting rod 706 is rotatably installed in the movable hole 705. Bolts are connected to the connecting seat 702, so that the cylinder 703 is fixedly installed on the connecting seat 702 by bolts. A bearing is installed in the movable hole 705, and the limiting rod 706 is rotatably installed in the movable hole 705 through the bearing.

[0029] Specifically, after cleaning is completed, the operator can retract cylinder 703. When cylinder 703 is retracted, it causes the lifting beam 704 to move upwards. As the lifting beam 704 rises, the limit rod 706 also shifts, eventually moving directly below the swing arm 603, which is already in a torsional state. In this way, the limit rod 706 effectively restricts the rotation of the swing arm 603, ensuring that the wiping roller 604 does not exert any additional pressure on the circuit board.

[0030] Working Principle: The main beam 1 is mounted on a robotic arm, which moves the entire device to transfer the circuit board. During transfer, the wiping roller 604 is first moved above the circuit board. Then, the robotic arm swings the wiping roller 604 downwards. Due to the obstruction of the circuit board, the wiping roller 604 rolls laterally along the surface of the circuit board, forcing the swing arm 603 to twist, thus cleaning the suction area below the vacuum suction cup 5 and ensuring the suction effect. After cleaning, the cylinder 703 can be retracted. Retracting the cylinder 703 causes the lifting beam 704 to move upwards. After the lifting beam 704 moves upwards, the limit rod 706 moves below the twisted swing arm 603, restricting the swing arm 603's rotation and preventing the wiping roller 604 from applying pressure to the circuit board, thus ensuring suction strength. After the transfer is complete, the cylinder 703 can be extended. After the cylinder 703 extends, the torsion spring 607 drives the swing arm 603 to rotate, causing the wiping roller 604 to return to its original position.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
