Description

Technical Field

[0001] This utility model belongs to the field of circuit board manufacturing technology, specifically relating to a multi-station bonding and pressing fixture. Background Technology

[0002] In the manufacturing and assembly of printed circuit boards (PCBs), the application of adhesive materials is a crucial step in achieving structural fixation, interlayer bonding, and functional integration. Traditional processes require laminating adhesive materials of specific shapes onto the PCB surface or between layers. Current lamination equipment generally employs a single-station sequential operation mode, completing adhesive lamination only one board at a time. As PCB production moves towards high-volume, high-cycle manufacturing, this sequential processing method severely restricts overall production line efficiency, resulting in low equipment utilization and high production costs.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a multi-station bonding and pressing fixture to realize continuous operation of PCB board bonding, improve equipment utilization and production efficiency, reduce production costs, and meet the needs of large-volume, high-cycle production.

[0005] Technical Solution: To achieve the above objectives, this utility model provides a multi-station bonding and pressing fixture, including a base plate, a rotating fixture connected to the top surface of the base plate, and a rolling device connected to the base plate on the upper side of the rotating fixture. The rolling device rolls the PCB board placed on the top surface of the rotating fixture. The rotating fixture includes a rotating drive mechanism and a turntable. The turntable is connected to the top surface of the rotating drive mechanism, and the bottom surface of the rotating drive mechanism is connected to the top surface of the base plate. The rotating drive mechanism drives the turntable to rotate. The top surface of the turntable has receiving chambers arranged in an array around the axis of the turntable, and the rolling device is located on the upper side of the receiving chambers. In traditional pressing equipment, the operator first adheres the adhesive material to the PCB surface, and then presses the adhesive material onto the PCB board one by one, resulting in low production efficiency. The production steps of this utility model include starting the rotating drive mechanism, which drives the turntable to rotate. As the turntable rotates, operators place PCB boards with adhesive backing material one by one into the receiving chamber. The receiving chamber rotates and passes under the rolling device, which presses the PCB boards placed in the receiving chamber together, realizing continuous PCB board pressing operation, improving equipment utilization and production efficiency, reducing production costs, and meeting the needs of large-volume, high-cycle production.

[0006] Furthermore, in the aforementioned multi-station bonding and pressing fixture, a sector-shaped plate is detachably connected to the top surface of the turntable, and a receiving chamber is located on the top surface of the sector-shaped plate. The sector-shaped plates are arranged in an array around the axis of the turntable. By placing the receiving chamber on the top surface of the sector-shaped plate and making the sector-shaped plate detachable, the sector-shaped plate can be replaced according to different PCB board bonding requirements, thereby improving the flexibility and adaptability of the equipment.

[0007] Furthermore, in the aforementioned multi-station bonding and pressing fixture, the sector-shaped plate has pin holes on both sides, and the top surface of the turntable has positioning holes corresponding to the pin holes. Positioning pins pass through the pin holes, and the sector-shaped plate is positioned and connected to the top surface of the turntable via these positioning pins. The sector-shaped plate is detachably connected to the turntable via fasteners. The positioning pins connecting the sector-shaped plate and the turntable improve the positioning accuracy of the sector-shaped plate and ensure the pressing quality.

[0008] Furthermore, in the aforementioned multi-station bonding and pressing fixture, the rolling device includes a support plate connected to the base plate. The support plate is vertically positioned, and an end plate is located on the side of the support plate near the turntable. The support plate and the end plate are connected by a connecting plate, which is connected to both ends of the end plate. The support plate, end plate, and connecting plate together form a rolling chamber. A roller is located within the rolling chamber, with its axis arranged radially along the turntable. The bottom of the roller and the top of the receiving chamber are kept at a distance. Rollers are located at both ends of the roller, and the two ends of the roller are connected to the support plate and the end plate respectively via the rollers. As the turntable rotates, the PCB board is gradually squeezed by the roller from the edge, which can effectively reduce the generation of air bubbles, ensure dental results, and improve bonding quality.

[0009] Furthermore, in the aforementioned multi-station bonding and pressing fixture, the support plate and end plate are respectively provided with waist holes on opposite sides. The long axis of the waist hole is vertically set, and the roller is adjustablely connected to the waist hole. An elastic mechanism is connected inside the waist hole. The elastic mechanism includes a spring connected to the lower side wall of the waist hole. The lower side of the spring is connected to a countersunk hole provided in the side wall of the waist hole. A support block is connected to the top of the spring. The top of the support block is correspondingly set with the roller. The spring presses the support block, and the support block applies an upward pushing force to the roller. The top surfaces of the support plate and end plate are respectively provided with threaded holes, which communicate with the waist holes. A headless screw is connected to the threaded hole, and the headless screw presses against the roller. The spring pushes the roller to the upper side of the waist hole, leaving a gap between the roller and the receiving chamber to avoid damage to the PCB board. When it is necessary to adjust the gap between the roller and the receiving chamber, the headless screw in the threaded hole is turned, causing the headless screw to press the roller, reducing the gap between the roller and the receiving chamber, meeting different production needs and improving the flexibility of the fixture.

[0010] Furthermore, in the aforementioned multi-station bonding and pressing fixture, a top plate is connected to the top surface of the support plate. The top plate is a square plate, and its four sides are connected to the support plate, end plate, and connecting plate respectively by fasteners. The top plate improves the structural strength of the rolling chamber, reduces deformation, and ensures the pressing quality.

[0011] Furthermore, in the aforementioned multi-station bonding and pressing fixture, a speed control knob and a power switch are connected to the top surface of the base plate. The speed control knob, power switch, and rotary drive mechanism are electrically connected. Pressing the power switch starts the rotary drive mechanism, and the speed control knob adjusts the rotation speed of the rotary drive mechanism, controls the turntable speed, and adjusts the pressing speed to meet different production needs and improve equipment flexibility.

[0012] Furthermore, in the aforementioned multi-station bonding and pressing fixture, the rotary drive mechanism includes a base connected to the top surface of the base plate, and the base is equipped with a meshing worm gear. A drive motor and the worm gear inside the base are connected to the side wall of the base. A rotary drive disk is rotatably connected to the top surface of the base, and the rotary drive disk is connected to the worm gear inside the base. The drive motor drives the rotary drive disk to rotate through the worm gear inside the base. The turntable is coaxially connected to the top surface of the rotary drive disk. A speed control knob can control the speed of the drive motor, thereby controlling the speed of the turntable. The worm gear drive system has a compact structure and a high reduction ratio, making it suitable for low-speed rotation applications.

[0013] Furthermore, in the aforementioned multi-station bonding and pressing fixture, the receiving chamber and the PCB board are correspondingly arranged. The bottom of the receiving chamber is provided with a clearance groove, and the opposite side of the receiving chamber is provided with a gripping groove, the bottom of which is lower than the bottom of the receiving chamber. The clearance groove prevents damage to the electrical components on the PCB, while the gripping groove facilitates the operator's gripping of the PCB board, improving material handling efficiency.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects: This utility model's multi-station bonding and pressing fixture allows operators to place PCB boards with adhesive backing material one by one into the receiving chamber as the turntable rotates. Simultaneously, as the receiving chamber rotates, the rolling device presses the PCB boards placed within it, achieving continuous PCB board pressing operations, improving equipment utilization and production efficiency, reducing production costs, and meeting the needs of high-volume, high-cycle production. The receiving chamber is located on the top surface of a fan-shaped plate, and the fan-shaped plate is detachable, allowing for replacement of the fan-shaped plate according to different PCB board pressing requirements, improving equipment flexibility and adaptability.
