Description

Technical Field

[0001] This utility model relates to the technical field of PCBA board flipping equipment, specifically to a flipping equipment for PCBA board production. Background Technology

[0002] In the production process of PCBA boards, the flipping operation is an indispensable part, especially when double-sided processing or inspection of PCBA boards is required. Traditional flipping equipment usually only flips the boards, and after flipping, it is impossible to place the PCBA boards back on the original conveyor belt, thus obstructing the placement of the flipped PCBA boards. Secondly, existing flipping mechanisms are difficult to adapt to PCBA boards of different sizes. In addition, some flipping devices are not accurate enough in their design and selection parameters, resulting in the flipping angle and length not meeting the actual needs, which can cause equipment damage or production interruption.

[0003] In response to the aforementioned problems, we propose a flipping device for PCBA board production. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a flipping device for PCBA board production to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flipping device for PCBA board production includes a first conveyor belt and a second conveyor belt for transporting PCBA boards, and a flipping assembly disposed between the first and second conveyor belts. The flipping assembly includes a left flipping section and a right flipping section with identical structures. The right flipping section includes a bracket, a movable plate slidably mounted within the bracket, and a lifting cylinder mounted on the bracket and driving the movable plate to rise and fall. A rotating shaft is provided within the movable plate, and a gear is provided within an opening on the rotating shaft. A gear ring is fitted around the rotating shaft, and the gear ring meshes with the output teeth of a first motor. The rotating shaft is provided with a second motor for driving the gear to rotate. The rotating shaft has an opening along its axial direction to divide the rotating shaft into an upper clamping section and a lower clamping section with identical structures. The upper clamping section includes a drive shaft and a rack plate inserted into the rotating shaft. One end of the drive shaft meshes with the gear, and the other end meshes with the rack plate, causing the rack plate to move linearly.

[0007] Furthermore, the rack plate is provided with a movable cylinder and a clamping plate at both ends, wherein the movable cylinder is used to drive the clamping plate to rotate, and the clamping plate is used to clamp the PCBA board; the clamping plate is movably connected to the rack plate, and a first connecting rod and a second connecting rod are provided between the movable cylinder and the clamping plate. One end of the first connecting rod is fixedly connected to the output end of the movable cylinder and the other end is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the clamping plate.

[0008] Furthermore, the movable cylinder is detachably connected to the rack plate, the first connecting rod is disposed inside the rack plate and slides with the rack plate, and the second connecting rod and the clamping plate are located in the groove opened on the rack plate.

[0009] Furthermore, the left and right flipping parts are connected by a crossbeam, which supports and fixes the relative positions of the left and right flipping parts. The piston rod of the lifting cylinder is fixed to the moving plate by a threaded connector. The first motor is mounted on the moving plate and is detachably connected to the moving plate. The second motor drives the gear to rotate, which drives the transmission shaft and then drives the rack plate to move to adjust the clamping distance.

[0010] Furthermore, the rotating shaft is circumferentially rotated with the moving plate, and the gear ring is circumferentially fixed to the rotating shaft by a flat key and axially locked by a nut.

[0011] Furthermore, the opening is used to facilitate the transfer of PCBA boards between the first conveyor belt and the second conveyor belt.

[0012] Furthermore, the gear is coaxially mounted with the rotating shaft, and the transmission shaft is clearance-fitted with the rotating shaft, allowing the transmission shaft to rotate within the rotating shaft.

[0013] This invention provides a flipping device for PCBA board production. It offers the following advantages: the upper and lower clamps are positioned between two conveyor belts, eliminating the need for large-scale modifications to existing equipment, thus reducing implementation costs and modification difficulty. Furthermore, the upper and lower clamps are located on opposite sides of the PCBA board, allowing it to be placed back in its original position after flipping, preventing obstruction on the original conveyor belt. The flipped PCBA board exposes its bottom components, facilitating detailed inspection and repair by maintenance personnel. Through optimized design of the flipping components, this device achieves efficient and precise flipping of the PCBA board between the first and second conveyor belts. The flipping assembly consists of a left flipping section and a right flipping section. Each flipping section includes components such as a bracket, a moving plate, a lifting cylinder, a rotating shaft, gears, a gear ring, a transmission shaft, and a rack plate. The lifting cylinder drives the moving plate to move up and down, thereby lifting the clamped PCBA board and preventing it from colliding with the conveyor belt during the flipping process. The rotation of the rotating shaft and the output gear of the first motor enables the rotation of the clamped PCBA board. The operation of the moving cylinder causes the clamping plate to rotate, so that the clamping plate is located on one side of the PCB board. Under the rotation of the gear driven by the second motor, the transmission shaft drives the rack plate to move, thereby simultaneously clamping both sides of the PCBA board.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See attached document Figures 1-7A flipping device for producing PCBA board 100 includes a first conveyor belt 1 and a second conveyor belt 2 for transporting PCBA board 100, and a flipping assembly 3 disposed between the first conveyor belt 1 and the second conveyor belt 2. The flipping assembly 3 includes a left flipping part 4 and a right flipping part 5 with identical structures. The right flipping part 5 includes a bracket 51, a movable plate 53 slidably mounted in the bracket 51, and a lifting cylinder 52 mounted on the bracket 51 and driving the movable plate 53 to rise and fall. The movable plate 53 is provided with a rotating shaft 55, and the rotating shaft 55 is toothed and located in an opening 551. The gear 541 is fitted with a gear ring 56 on the rotating shaft 55. The gear ring 56 meshes with the output teeth of the first motor 531. The rotating shaft 55 is equipped with a second motor 54 for driving the gear 541 to rotate. The rotating shaft 55 has an opening 551 along the axial direction to divide the rotating shaft 55 into an upper clamping part 58 and a lower clamping part 59 with the same structure. The upper clamping part 58 includes a transmission shaft 57 and a rack plate 584 inserted into the rotating shaft 55. One end of the transmission shaft 57 meshes with the gear 541 and the other end meshes with the rack plate 584, so that the rack plate 584 moves linearly and achieves synchronous movement.

[0024] Specifically, the bracket 51 is used to support the entire tilting assembly 3 to ensure its stable operation during operation; the moving plate 53 moves up and down under the drive of the lifting cylinder 52.

[0025] The rack plate 584 is provided with a movable cylinder 581 and a clamping plate 585 at both ends, respectively. The movable cylinder 581 is used to drive the clamping plate 585 to rotate, and the clamping plate 585 is used to clamp the PCBA board 100. The clamping plate 585 is movably connected to the rack plate 584. A first connecting rod 582 and a second connecting rod 583 are provided between the movable cylinder 581 and the clamping plate 585. One end of the first connecting rod 582 is fixedly connected to the output end of the movable cylinder 581 and the other end is hinged to one end of the second connecting rod 583. The other end of the second connecting rod 583 is hinged to the clamping plate 585 to realize the rotation of the clamping plate 585.

[0026] Specifically, the rack plate 584 achieves linear motion through the drive shaft 57, thereby adjusting the clamping distance and clamping the PCBA board 100; the clamping plate 585 is used to clamp the PCBA board 100 to ensure its stability and safety during the flipping process.

[0027] The movable cylinder 581 is detachably connected to the rack plate 584. The first connecting rod 582 is disposed inside the rack plate 584 and slides with the rack plate 584 to ensure linear motion stability. The second connecting rod 583 and the clamping plate 585 are located in the groove opened on the rack plate 584.

[0028] Specifically, the movable cylinder 581 drives the rotation of the clamping plate 585 to achieve the clamping and release of the PCBA board 100.

[0029] The left flipping part 4 and the right flipping part 5 are connected by a crossbeam, which is used to support and fix the relative positions of the left and right flipping parts 5. The piston rod of the lifting cylinder 52 is fixed to the moving plate 53 by a threaded connector. The first motor 531 is mounted on the moving plate 53 and is detachably connected to the moving plate 53. The second motor 54 drives the gear 541 to rotate, and the gear 541 drives the transmission shaft 57, which in turn drives the rack plate 584 to move to achieve the adjustment of the clamping distance.

[0030] The rotating shaft 55 is circumferentially rotated with the moving plate 53 to realize the rotational movement of the rotating shaft 55. The toothed ring 56 is circumferentially fixed to the rotating shaft 55 by a flat key and axially locked by a nut.

[0031] Specifically, the rotating shaft 55 rotates to cause the PCBA board 100 to flip, and at the same time the rotating shaft 55 is divided into upper and lower clamping parts 59 for clamping the PCBA board 100.

[0032] The opening 551 is used to transfer the PCBA board 100 between the first conveyor belt 1 and the second conveyor belt 2.

[0033] The gear 541 is coaxially mounted with the rotating shaft 55 to achieve rotational drive of the gear 541. The transmission shaft 57 is clearance-fitted with the rotating shaft 55 to allow the transmission shaft 57 to rotate within the rotating shaft 55.

[0034] Working principle: After the equipment is started, the first conveyor belt 1 transports the PCBA board 100 forward to the designated position below the flipping assembly 3. At this time, the lifting cylinders 52 of the left flipping part 4 and the right flipping part 5 are in the retracted state, and the moving plate 53 is in the low position; the rack plates 584 of the upper clamping part 58 and the lower clamping part 59 are in the open state (clamping distance is the maximum), and the clamping plate 585 is in the open posture (parallel to the transmission direction of the PCBA board 100) driven by the moving cylinder 581, waiting to be clamped.

[0035] Lifting adjustment: The piston rod of the lifting cylinder 52 extends, driving the moving plate 53 to slide upward along the bracket 51, so that the rotating shaft 55 (including the upper clamp 58 and the lower clamp 59) moves to the height of the PCBA board 100, ensuring that the PCBA board 100 is located between the upper and lower clamping plates 585.

[0036] Spacing Adjustment: The second motor 54 starts, driving gear 541 to rotate. Gear 541 drives the transmission shaft 57 to rotate by meshing with the tooth structure at the end of the transmission shaft 57; the other end of the transmission shaft 57 meshes with the rack plate 584, converting the rotational motion into the linear motion of the rack plate 584. The rack plates 584 of the upper and lower clamping parts 59 move synchronously towards each other, reducing the clamping spacing until the clamping plate 585 contacts the edge of the PCBA board 100.

[0037] Clamping and fixing: The piston rod of the movable cylinder 581 extends, pushing the first connecting rod 582 to slide inside the rack plate 584. The first connecting rod 582 drives the second connecting rod 583 to rotate (the second connecting rod 583 is hinged to the clamping plate 585), which finally drives the clamping plate 585 to rotate around the movable connection (from the horizontal open state to the vertical clamping state), clamping it from both sides of the PCBA board 100 to ensure that it will not loosen or shift during the flipping process.

[0038] Lifting off the conveyor belt: The lifting cylinder 52 continues to push the moving plate 53 upward, so that the clamped PCBA board 100 is completely detached from the surface of the first conveyor belt 1, avoiding interference with the conveyor belt during flipping.

[0039] Rotation and flipping: The first motor 531 starts, and its output teeth mesh with the gear ring 56 outside the rotating shaft 55, driving the gear ring 56 to rotate, which in turn drives the rotating shaft 55, the transmission shaft 57, the rack plate 584, and the clamped PCBA board 100 to rotate synchronously around the axis. According to production requirements, the rotating shaft 55 can rotate 180° (to achieve double-sided flipping) or other angles to complete the flipping action of the PCBA board 100.

[0040] Lowering and Alignment: After the flipping is completed, the first motor 531 stops, and the rotating shaft 55 and PCBA board 100 maintain a fixed angle. The piston rod of the lifting cylinder 52 retracts, driving the moving plate 53 to lower the PCBA board 100 until the lower surface of the PCBA board 100 is close to the transmission plane of the second conveyor belt 2.

[0041] Releasing PCBA board 100: The piston rod of the moving cylinder 581 retracts, which drives the clamping plate 585 to rotate in the opposite direction through the first connecting rod 582 and the second connecting rod 583 (returning from the vertical clamping state to the horizontal open state), releasing PCBA board 100 and placing it stably on the second conveyor belt 2.

[0042] Reset to prepare for the next cycle: The second motor 54 drives the gear 541 in the reverse direction, and the rack plate 584 moves synchronously in the reverse direction to restore the initial open state; the lifting cylinder 52 continues to retract, and the moving plate 53 descends to its original position, waiting for the next PCBA board 100 to be transferred to the position, and repeats the above process.
