Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a circuit board stacking positioning device. Background Technology

[0002] In the electronics manufacturing industry, the production of printed circuit boards (PCBs) often involves multi-layer stacking and positioning processes, which require the rapid and precise stacking of multiple circuit boards or pads at specific workstations.

[0003] Traditional operations rely heavily on manual labor or simple single-arm robotic arms for handling and stacking, resulting in significant problems such as low efficiency, high labor intensity, positioning accuracy affected by human factors, and difficulty in achieving continuous automated production. Although some automated handling equipment exists on the market, its structure is often complex, or it can only achieve unidirectional, single-station pick-and-place functions, with a long idle travel time within a work cycle, making it difficult to further improve the overall cycle time. In addition, existing equipment often lacks convenient and precise fine-tuning capabilities for minor positional deviations that may occur during the stacking process, affecting the final stacking accuracy.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a circuit board stacking positioning device to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0005] The purpose of this utility model is to provide a circuit board stacking positioning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circuit board stacking positioning device, comprising:

[0007] support;

[0008] A rotating platform, mounted on a support frame;

[0009] The slewing arm is rotatably mounted on the support and connected to the drive end of the rotating platform, which drives it to rotate.

[0010] Two working units are respectively located at both ends of the slewing arm; each working unit includes:

[0011] The lifting module includes a slider fixed on a rotary arm, a slide rail that slides with the slider, a cylinder that drives the slide rail to move up and down along the slider, and a mounting plate that connects the slide rail and the cylinder piston rod.

[0012] The fine-tuning platform, mounted on the mounting plate, is used to fine-tune the position of the adsorption component in the horizontal plane.

[0013] The adsorption component, located below the fine-tuning platform, is used to adsorb or release the circuit board.

[0014] Specifically, the rotating platform drives the rotary arm to reciprocate 180 degrees, enabling two centrally symmetrically arranged working units fixed at both ends to work alternately. After the adsorption component of one working unit descends via the lifting module and picks up the circuit board, the rotary arm rotates to deliver the circuit board to another workstation, while the other working unit enters the ready-to-pick-up state. This achieves continuous picking and unloading within one work cycle, significantly improving the efficiency and automation of stacking positioning. At the same time, the fine-tuning platform, through the cooperation of the first and second screws, enables precise positional adjustments of the adsorption component in two vertical directions within the horizontal plane, effectively ensuring the positional accuracy of the stacked circuit boards and reducing positioning errors.

[0015] Preferred fine-tuning platforms include:

[0016] The base is fixed to the mounting plate;

[0017] Two sliding members are slidably disposed within the base along a first direction;

[0018] The mounting platform is positioned between two sliding parts.

[0019] The sliding shaft has its two ends fixed to two sliding parts, and passes through the mounting platform to be slidably connected to the mounting platform;

[0020] The first screw has two ends rotatably mounted on two sliding parts and passes through the mounting platform, engaging with the mounting platform threadedly. Rotating the first screw can drive the mounting platform to move along the sliding shaft.

[0021] A back plate is provided on one side of the base, and a groove extending in the second direction is provided on it;

[0022] The second screw is slidably disposed in the groove, and its end passes through the back plate and is threadedly engaged with the mounting platform. Rotating the second screw can drive the mounting platform to move along the first direction.

[0023] The first direction and the second direction are perpendicular to each other.

[0024] Specifically, by setting up a sliding component that can slide along a first direction, along with a sliding shaft and a first screw connected thereto, the mounting platform can achieve precise linear displacement adjustment in a horizontal direction. At the same time, by setting up a back plate with a sliding groove on the side of the base and a second screw that cooperates with it, the mounting platform can independently perform fine-tuning of its position in a second direction perpendicular to it. This dual adjustment mechanism realizes independent, precise and stable position calibration of the adsorption component in two orthogonal directions in the horizontal plane, effectively compensating for equipment installation errors and deviations caused by long-term operation, thereby ensuring high positioning accuracy and repeatability consistency during the picking, placing and stacking of circuit boards.

[0025] Preferably, the adsorption component is a vacuum adsorption plate, which is fixedly connected to the bottom of the installation platform.

[0026] Specifically, by using a vacuum adsorption plate as an adsorption component and directly fixing it under a bidirectional fine-tuned mounting platform, it can inherit the precise calibration posture of the fine-tuning platform in two orthogonal directions, thereby ensuring the positioning accuracy and posture consistency of the vacuum adsorption plate when picking up and placing circuit boards. At the same time, the vacuum adsorption method provides a uniform and adjustable adsorption force, which can stably and non-destructively adsorb circuit boards with flat surfaces, avoiding scratches or mechanical stress on the board surface, improving the reliability of operation and the protection of the circuit boards. In addition, the structure is direct and stable, reducing force transmission links and improving the overall system response speed and rigidity, which is conducive to achieving efficient and precise automated stacking operations.

[0027] Preferably, the rotating platform drives the rotary arm to reciprocate 180 degrees.

[0028] Specifically, the rotary platform drives the rotary arm to reciprocate 180 degrees, enabling two working units located at opposite ends of the rotary arm to precisely alternate positions between two workstations with the simplest and most efficient motion trajectory. While one working unit is performing a picking or placing operation, the other working unit moves to the other workstation to complete preparation or wait, thus integrating the picking, moving, and unloading actions into a continuous rotation cycle, eliminating idle travel and significantly improving the equipment's work cycle and overall production efficiency. At the same time, the 180-degree fixed rotation angle motion control is simple, precise, and reliable, which helps ensure the consistency of each position exchange and provides a stable spatial reference for subsequent precision stacking operations.

[0029] Preferably, the two working units at both ends of the slewing arm have identical structures and are arranged in a centrally symmetrical manner.

[0030] Specifically, the two working units at both ends of the rotary arm adopt a consistent structure and are arranged in a centrally symmetrical manner. This ensures that when the rotary arm rotates 180 degrees under the drive of the rotating platform, the spatial positions and motion trajectories of the two working units are completely mirrored and interchangeable. This not only ensures the motion balance and stability of the equipment when switching between the material picking and unloading stations, reducing vibration caused by the shift of the center of gravity, and improving the smoothness and lifespan of the equipment, but also achieves complete consistency of the functions and actions of the two stations, simplifying the motion control logic and programming, and reducing the complexity of debugging and maintenance. At the same time, this symmetrical layout is the core structural foundation for the equipment to achieve efficient, continuous, and alternating operations, fundamentally optimizing the work cycle and enabling the equipment to complete the material picking and unloading cycle with the simplest mechanical movements, significantly improving the efficiency and reliability of automated stacking.

[0031] Compared with the prior art, the present invention provides a circuit board stacking positioning device, which has the following beneficial effects:

[0032] By adopting a rotary arm structure with dual symmetrical working units, coupled with a rotary platform that drives it to reciprocate 180 degrees, continuous and seamless alternation of material picking and unloading stations is achieved, completely eliminating the idle travel waiting time of traditional single-arm equipment and significantly improving the production efficiency and automation level of stacking operations. At the same time, the precision fine-tuning platform integrated into each working unit provides independent position calibration functions in two vertical directions in the horizontal plane, which can effectively compensate for and correct the minor deviations generated during the picking and placing of circuit boards, thereby ensuring high precision and high repeatability of the stacking process. The overall structure is compact and the operation is stable and reliable. Attached Figure Description

[0044] Example:

[0045] Please see Figures 1-7 This utility model provides a technical solution: a circuit board stacking positioning device, comprising:

[0046] 10 brackets;

[0047] The rotating platform 20 is mounted on the support 10;

[0048] The rotating arm 30 is rotatably mounted on the bracket 10 and connected to the drive end of the rotating platform 20, and is driven to rotate by the rotating platform 20.

[0049] Two working units are respectively located at both ends of the slewing arm 30; each working unit includes:

[0050] The lifting module 40 includes a slider 410 fixed on the rotary arm 30, a slide rail 420 that slides with the slider 410, a cylinder 430 that drives the slide rail 420 to rise and fall along the slider 410, and a mounting plate 440 that connects the slide rail 420 and the piston rod of the cylinder 430.

[0051] The fine-tuning platform 50 is set on the mounting plate 440 and is used to fine-tune the position of the adsorption component 60 in the horizontal plane.

[0052] The adsorption component 60 is located below the fine-tuning platform 50 and is used to adsorb or release the circuit board.

[0053] Specifically, the rotating platform 20 drives the rotary arm 30 to reciprocate 180 degrees, enabling two working units fixed at both ends and arranged in a centrally symmetrical manner to work alternately. After the adsorption component 60 of one working unit is lowered by the lifting module 40 and completes the pickup of the circuit board, the rotary arm 30 rotates to send the circuit board to another work station. At the same time, the other working unit enters the ready-to-pick-up state, thereby realizing the continuous action of picking up and putting down materials within one work cycle, which significantly improves the efficiency and automation of stacking positioning. Meanwhile, the fine-tuning platform 50, through the cooperation of the first screw 550 and the second screw 570, realizes the precise position fine-tuning of the adsorption component 60 in two vertical directions in the horizontal plane, effectively ensuring the positional accuracy of the stacked circuit boards and reducing positioning errors.

[0054] Preferably, the fine-tuning platform 50 includes:

[0055] The base 510 is fixed to the mounting plate 440;

[0056] Two sliding members 520 are slidably disposed within the base 510 along the first direction;

[0057] The mounting platform 530 is set between two sliding parts 520;

[0058] The sliding shaft 540 has its two ends fixed to two sliding parts 520 respectively, and passes through the mounting platform 530 and is slidably connected to the mounting platform 530;

[0059] The first screw 550 has its two ends rotatably mounted on two sliding parts 520 and passes through the mounting platform 530, and is threadedly engaged with the mounting platform 530. Rotating the first screw 550 can drive the mounting platform 530 to move along the sliding shaft 540.

[0060] A back plate 560 is disposed on one side of the base 510, and a groove 561 extending in the second direction is provided thereon;

[0061] The second screw 570 is slidably disposed in the slide groove 561, and its end passes through the back plate 560 and is threadedly engaged with the mounting platform 530. Rotating the second screw 570 can drive the mounting platform 530 to move along the first direction.

[0062] The first direction and the second direction are perpendicular to each other.

[0063] It should be noted here that the instruction manual includes... Figure 7 In this context, A represents the first direction. (See the instruction manual attached.) Figure 7 In this context, B represents the second direction.

[0064] Specifically, by setting a sliding member 520 that can slide along the first direction and a sliding shaft 540 and a first screw 550 connected thereto, the mounting platform 530 can achieve precise linear displacement adjustment in a horizontal direction; at the same time, by setting a back plate 560 with a sliding groove 561 on the side of the base 510 and a second screw 570 that cooperates thereto, the mounting platform 530 can independently perform position fine adjustment in a second direction perpendicular to it; this dual adjustment mechanism realizes independent, precise and stable position calibration of the adsorption component 60 in two orthogonal directions in the horizontal plane, effectively compensating for equipment installation errors and deviations caused by long-term operation, thereby ensuring high positioning accuracy and repeatability consistency in the process of picking up and stacking circuit boards.

[0065] Preferably, the adsorption component 60 is a vacuum adsorption plate, which is fixedly connected to the bottom of the installation platform 530.

[0066] Specifically, by using a vacuum adsorption plate as the adsorption component 60 and directly fixing it below the bidirectional fine-tuned mounting platform 530, it can inherit the precise calibration posture of the fine-tuning platform 50 in two orthogonal directions, thereby ensuring the positioning accuracy and posture consistency of the vacuum adsorption plate when picking up and placing circuit boards. At the same time, the vacuum adsorption method provides a uniform and adjustable adsorption force, which can stably and non-destructively adsorb circuit boards with flat surfaces, avoiding scratches or mechanical stress on the board surface, improving the reliability of operation and the protection of the circuit board. In addition, the structure is direct and stable, reduces force transmission links, improves the response speed and rigidity of the overall system, and is conducive to achieving efficient and precise automated stacking operations.

[0067] Preferably, the rotating platform 20 drives the rotary arm 30 to reciprocate 180 degrees.

[0068] Specifically, the rotating platform 20 drives the rotary arm 30 to reciprocate 180 degrees, enabling the two working units located at both ends of the rotary arm 30 to precisely alternate positions between the two workstations with the simplest and most efficient motion trajectory. While one working unit is performing a picking or placing operation, the other working unit moves to the other workstation to complete preparation or wait, thus integrating the picking, moving, and unloading actions into a continuous rotation cycle, eliminating idle travel and waiting, and greatly improving the working cycle and overall production efficiency of the equipment. At the same time, the 180-degree fixed rotation angle motion control is simple, and the positioning is accurate and reliable, which helps to ensure the consistency of each position exchange and provides a stable spatial reference for subsequent precision stacking operations.

[0069] Preferably, the two working units at both ends of the slewing arm 30 have the same structure and are arranged in a centrally symmetrical manner.

[0070] Specifically, the two working units at both ends of the rotary arm 30 adopt a consistent structure and are arranged in a centrally symmetrical manner. This ensures that when the rotary arm 30 rotates 180 degrees under the drive of the rotating platform 20, the spatial positions and motion trajectories of the two working units are completely mirrored and interchangeable. This not only ensures the motion balance and stability of the equipment when switching between the material picking station and the material unloading station, reduces vibration caused by the shift of the center of gravity, and improves the smoothness and lifespan of the equipment, but also achieves complete consistency of the functions and actions of the two stations, simplifies the motion control logic and programming, and reduces the complexity of debugging and maintenance. At the same time, this symmetrical layout is the core structural foundation for the equipment to achieve efficient, continuous, and alternating operations. It fundamentally optimizes the working cycle, enabling the equipment to complete the material picking and unloading cycle with the simplest mechanical movements, significantly improving the efficiency and reliability of automated stacking.

[0071] Working principle: In the initial state, the working unit at one end of the rotary arm 30 is located at the loading station. The cylinder 430 of its lifting module 40 drives the slide rail 420 and mounting plate 440 to descend, so that the vacuum adsorption plate 60 at the bottom of the fine-tuning platform 50 contacts and adsorbs the circuit board. Then, the cylinder 430 lifts the adsorption plate 60. Next, the rotating platform 20 drives the rotary arm 30 to rotate 180 degrees, switching the working unit with the adsorbed circuit board to the unloading station, and at the same time, switching another empty working unit to the loading station. The working unit that reaches the unloading station repeats the descent action. At the same time, the working unit located at the loading station begins to perform the next material picking action. This cycle repeats, realizing continuous and alternating automated operation of material picking and unloading at the two stations. According to the requirements, the first screw 550 and the second screw 570 of its fine-tuning platform 50 are used for bidirectional position fine-tuning in the horizontal plane to precisely control the adsorption and placement position of the circuit board.
