Two sets of slide rails are vertically mounted on one side of the movable frame, and sliders are slidably connected to the outer sides of both sets of slide rails. A fixed plate is connected to one side of both sets of sliders. A rubber plate is mounted on one side of the fixed plate, and one side of the rubber plate is in contact with the other side of the PCB board body.

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 7 As shown:

[0028] This utility model provides a pick-and-place machine for PCB board processing, including a pick-and-place machine body 2 installed on the top of a workbench 1, and a control console installed on one side of the top of the workbench 1. Two sets of side plates 3 are slidably connected to the top of the workbench 1 and directly below the pick-and-place machine body 2. Three sets of conveying mechanisms with the same structure are installed between the two sets of side plates 3. The top of the conveying mechanism in the middle position is placed on the top of the PCB board body 4. Two sets of electric push cylinders 5 are vertically installed on the top of the workbench 1 through a fixed platform. The output ends of the two sets of electric push cylinders 5 are connected to a support plate 6. Abutment plates 7 are installed at the four corners of the top of the support plate 6. The tops of the four sets of abutment plates 7 are all in contact with the bottom of the PCB board body 4. Clamping mechanisms are provided on the top of the workbench 1 and on both sides of the PCB board body 4.

[0029] The workbench 1 is equipped with two sets of slide rails 8 at its top. The bottom sides of the two sets of side plates 3 are each equipped with sliders 9 that can slide and connect with the corresponding slide rails 8. Electric push cylinders 10 are fixedly installed on the top of the workbench 1 and on both sides of the two sets of slide rails 8 via connecting frames. The output ends of the two sets of electric push cylinders 10 on the same side are fixedly connected to the corresponding side plates 3, allowing for precise adjustment of the distance between the two sets of side plates 3. This enables quick adaptation to PCBs of different widths without disassembling or replacing parts, reducing operational complexity. The sliding cooperation between the sliders 9 and the slide rails 8 ensures smooth movement of the side plates 3, preventing misalignment of the conveying mechanism due to jamming during distance adjustment and ensuring conveying accuracy. The synchronous drive of the two sets of electric push cylinders 10 on the same side ensures balanced force on the side plates 3, preventing unilateral tilting and further improving structural stability.

[0030] The conveying mechanism includes two sets of spline sleeves 11 rotatably connected to opposite sides of the two sets of side plates 3. Synchronous pulleys 12 are mounted on the outer sides of each spline sleeve 11. A conveyor belt 13 is installed between the two sets of synchronous pulleys 12 on the same side plate 3. A spline shaft 14 connects any two sets of spline sleeves 11 on opposite sides of the two sets of side plates 3. A reduction motor 15 is mounted on the outer side of one set of side plates 3. The output end of the reduction motor 15 is connected to one set of spline shafts 14, ensuring the transmission connection is maintained even when the spacing between the two sets of side plates 3 is adjusted. This ensures the operation of the conveyor belt 13 and solves the problem that traditional fixed-axis-pitch conveying mechanisms cannot adapt to width adjustments. The reduction motor 15 drives the corresponding synchronous pulleys 12 and conveyor belt 13 to rotate via the spline shaft 14, enabling independent operation of multiple conveying mechanisms and facilitating the movement of the PCB board.

[0031] The support plate 6 has four vertically mounted telescopic rods 16 at its top corners. Each telescopic rod 16 is fitted with a spring 17 on its outer side. The two ends of the spring 17 are respectively abutted against the abutment plate 7 and the support plate 6. When the abutment plate 7 lifts the PCB board, the spring 17 absorbs the impact force through elastic deformation, avoiding squeezing damage to the PCB board (especially thin substrate) caused by rigid contact. At the same time, the preload of the spring 17 can compensate for the height difference of PCB boards of different thicknesses, improving adaptability.

[0032] The clamping mechanism includes a fixed frame 18 vertically mounted on the top of the workbench 1. Two sets of slide rails 19 are vertically mounted on one side of the fixed frame 18. Slider 20s are slidably connected to the outer sides of both sets of slide rails 19. A fixed plate 21 is connected to one side of both sets of sliders 20s. A rubber plate is mounted on one side of the fixed plate 21, and one side of the rubber plate is in contact with one side of the PCB board body 4. An electric push cylinder 22 is vertically mounted on one side of the fixed frame 18. The output end of the electric push cylinder 22 is fixedly connected to the bottom end of the fixed plate 21, which can position and block the PCB board to prevent it from moving excessively and affecting the mounting accuracy.

[0033] The clamping mechanism further includes a movable frame 23 vertically mounted on the top of the workbench 1 and located on the opposite side of the fixed frame 18. Two sets of slide rails 24 are vertically mounted on one side of the movable frame 23. Sliding sliders 25 are slidably connected to the outer sides of both sets of slide rails 24. A fixed plate 26 is connected to one side of both sets of sliding sliders 25. A rubber plate 2 is mounted on one side of the fixed plate 26, and one side of the rubber plate 2 is in contact with the other side of the PCB board body 4. Two mounting slots are provided at the bottom of the movable frame 23. The mounting slots are equipped with rollers 27. Two sets of electric push cylinders 28 are mounted on one side of the top of the workbench 1 via a connecting seat. The output ends of the two sets of electric push cylinders 28 are fixedly connected to one side of the moving frame 23. An electric push cylinder 29 is vertically mounted on one side of the moving frame 23. The output end of the electric push cylinder 29 is fixedly connected to the bottom end of the fixed plate 26. The distance between the electric push cylinder 29 and the PCB board can be flexibly adjusted to adapt to PCB boards of different widths. The fixed plate 26 is raised and lowered in conjunction with the electric push cylinder 29 to achieve clamping size adaptation.

[0034] Among them, the two sets of side plates 3 are equipped with limit plates 30 at the top of the conveying mechanism in the middle position. The bottom end of the limit plate 30 is attached to the top end of the PCB board body 4. The limit plate 30 is attached to the PCB board from the top end and forms an upper and lower limit with the bottom end abutment plate 7 to prevent the PCB board from tilting upward due to the force of the robotic arm during the mounting process.

[0035] The working principle of this embodiment:

[0036] First, the electric pusher cylinder 10 is started via the control console. Its output end pushes the side plate 3 to slide along the slide rail 8, thereby precisely adjusting the distance between the two sets of side plates 3 so that the conveying mechanism can adapt to the width of the PCB board to be mounted. At the same time, the geared motor 15 is started, which drives the spline shaft 14 to rotate. The spline shaft 14 drives the synchronous wheel 12 to rotate through the spline sleeve 11, which in turn drives the conveyor belt 13 to rotate, preparing for the PCB board to be transported.

[0037] Next, the front-end feeding mechanism transports the PCB board onto the conveyor belt 13. When the PCB board moves to the conveyor mechanism in the middle position along the conveyor belt 13, the electric push cylinder 22 on one side of the fixed frame 18 is activated, pushing the fixed plate 21 to rise along the slide rail 19, so that the rubber plate on the fixed plate 21 fits against one side of the PCB board, achieving initial positioning and blocking.

[0038] Subsequently, the second electric pusher cylinder 5 is activated, and its output end pushes the support plate 6 upward. The abutment plate 7 at the top of the support plate 6, with the buffer cooperation of the telescopic rod 16 and the spring 17, fits against the bottom of the PCB board and pushes it upward until the top of the PCB board contacts the bottom side of the limiting plate 30 on the two sets of side plates 3. The second electric pusher cylinder 5 then stops working. Immediately afterwards, the fifth electric pusher cylinder 29 pushes the second fixed plate 26 upward along the slide rail 3 24. At the same time, the third electric pusher cylinder 28 pushes the moving frame 23 to move to one side of the PCB board through the bottom roller 27, so that the rubber plate 2 on the second fixed plate 26 fits tightly against the other side of the PCB board, completing the clamping and fixing of the PCB board and ensuring no offset during mounting.

[0039] Finally, the pick-and-place machine body 2 is started to place components on the fixed PCB board; after placement, the clamping mechanism is released (electric pusher cylinder 4 22 and electric pusher cylinder 5 29 drive the fixed plate 1 21 and fixed plate 2 26 to reset, electric pusher cylinder 3 28 pulls the moving frame 23 to move back), electric pusher cylinder 2 5 retracts, support plate 6 drives the abutment plate 7 to descend, and the PCB board falls back onto the conveyor belt 13, which then transports it out, completing the entire placement process.

[0040] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
