Technical Field

[0001] This utility model relates to the field of electronic manufacturing technology, specifically to a conveying buffer assembly for a PCB board receiving machine. Background Technology

[0002] In the PCB manufacturing process, the PCB receiving machine is an important piece of equipment used to collect and organize the finished PCBs. However, when the PCB receiving machine is transporting PCBs, due to high-speed movement and stacking, the PCBs are easily subjected to impact and vibration, which can lead to damage to the board surface, such as solder joint cracking and loosening of components. This seriously affects the quality and reliability of the PCBs. Therefore, buffer components are of great significance for improving the production quality and efficiency of PCBs.

[0003] When using the existing PCB take-up machine's conveyor buffer assembly, the buffer assembly can only abut and buffer the PCB boards on the take-up machine's conveyor track, but it cannot adjust the position of the PCB boards on the track, nor can it make the PCB boards themselves be positioned neatly, thus affecting their subsequent stacking effect, resulting in the problem of low practicality of the existing assembly.

[0004] Therefore, this utility model introduces a conveying buffer assembly for a PCB board receiving machine. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a conveying buffer assembly for a PCB receiving machine. This assembly has the advantage of being able to adjust the position of the PCBs conveyed by the receiving machine before buffering them, thereby facilitating their subsequent collection and stacking, and solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a conveying buffer assembly for a PCB board receiving machine, comprising a body, a cylinder fixedly mounted on the body, connecting rods rotatably connected to both sides of one end of the cylinder, a sliding block rotatably connected to one end of each of the two connecting rods, a fixed track slidably connected to the sliding block, and the fixed track being fixedly connected to the body, and a guide plate fixedly mounted on the bottom of the sliding block.

[0007] Preferably, a rack is slidably connected inside the machine body, with one end of the rack penetrating the machine body.

The output shaft of the rotating motor passes through a rotating rod and is fixedly connected to the rotating rod. A rotating rod is fixedly and rotatably connected to one end of the rotating rod. A movable block is rotatably connected to one end of the rotating rod, and the movable block is slidably connected to the clamping frame. A clamping block is fixedly installed on the movable block.

[0008] Preferably, the machine body is fixedly connected to a connecting spring, one end of the connecting spring is fixedly connected to a rubber buffer plate, the rubber buffer plate is fixedly connected to a telescopic rod, and one end of the telescopic rod is fixedly connected to the machine body, the telescopic rod passing through the interior of the connecting spring.

[0009] Preferably, the machine body is rotatably connected to a rotating shaft, one end of which is coaxially fixedly connected to a spur gear, which meshes with a rack, and an abutment block is fixedly installed on the side of the clamping frame.

[0010] Preferably, a ratchet is coaxially fixedly connected to the rotating shaft, the ratchet abuts against a pawl, the pawl is rotatably connected to a connecting shaft, one end of the connecting shaft is fixedly connected to the top of the machine body, the pawl is fixedly connected to a torsion spring, and one end of the torsion spring is fixedly connected to the machine body, and the connecting shaft passes through the interior of the torsion spring.

[0011] Preferably, the clamping frame is L-shaped and has a slot.

[0012] Preferably, the number of abutment blocks is four, and every two abutment blocks form a group.

[0013] Preferably, the other end of the rotating shaft is provided with a knob for rotating the rotating shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The conveying buffer assembly of this PCB winding machine, through the setting of the clamping assembly, first places the entire device on the conveyor frame of the winding machine during use. Then, by rotating the rotating shaft, the spur gear fixedly connected to it is rotated, thereby driving the two racks meshing with the spur gear to retract into the machine body. During the retraction of the racks, the clamping frame connected to its end moves to both sides of the conveyor frame. Finally, the clamping frame abuts against both sides of the conveyor frame, initially fixing the buffer assembly as a whole. Then, by rotating the output shaft of the rotating motor, the rotating rod one and rotating rod two are extended, thereby pushing the movable block connected to one end of the rotating rod two to move forward along the track, so that the movable block is fixedly connected to the clamping block and clamped on the side of the conveyor frame. In this way, under the action of the two sets of clamping assemblies, the buffer assembly can be effectively installed on the conveyor frame of the winding machine.

[0016] 2. The conveying buffer assembly of this PCB receiving machine, through the setting of the guide assembly, when the buffer assembly is installed on the conveyor frame, when a PCB board is conveyed, the extension and retraction of the cylinder drives the two connecting rods at its ends to retract inward, thereby causing the sliding block at the end of the connecting rod to move along the trajectory of the fixed track towards the center of the machine body. This causes the guide plate connected to the bottom of the sliding block to perform an inward clamping action, thereby limiting and guiding the conveyed PCB board to be conveyed in a centered position, and abutting against the connecting spring in the assembly for buffering, thus facilitating the quick removal and stacking of the PCB board later.

[0024] 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.

[0025] Please see Figure 1-6 The conveying buffer assembly of the PCB receiving machine includes a body 1. A cylinder 17 is fixedly installed on the body 1. Connecting rods 18 are rotatably connected to both sides of one end of the cylinder 17. Sliding blocks 19 are rotatably connected to one end of each connecting rod 18. A fixed track 20 is slidably connected to the sliding block 19, and the fixed track 20 is fixedly connected to the body 1. A guide plate 21 is fixedly installed at the bottom of the sliding block 19. The cylinder 17, as a power source, can quickly respond to and precisely control the movement of the connecting rods 18, thereby driving the sliding block 19 and the bottom guide plate 21 to make rapid adjustments. When the PCB board enters the conveying area, the guide plate 21 effectively reduces the impact speed of the PCB board through its flexible contact method, preventing it from hitting the buffer assembly at too high a speed, which would cause the PCB board to crack at the solder joints, loosen components, or other phenomena.

[0026] The machine body 1 has a rack 2 slidably connected inside, with one end of the rack 2 penetrating through the machine body 1. A clamping frame 3 is fixedly installed at one end of the rack 2, and a fixed seat 4 is fixedly installed on the clamping frame 3. A rotary motor 5 is fixedly installed on the fixed seat 4, and the output shaft of the rotary motor 5 passes through the fixed seat 4 and is rotatably connected to the fixed seat 4. The output shaft of the rotary motor 5 passes through a rotating rod 6 and is fixedly connected to the rotating rod 6. A rotating rod 7 is fixedly and rotatably connected at one end of the rotating rod 6, and a movable block 8 is rotatably connected at one end of the rotating rod 7. The movable block 8 is slidably connected to the clamping frame 3, and a clamping block 9 is fixedly installed on the movable block 8. Since the clamping frame 3 and the clamping block 9 can be flexibly adjusted according to the size and shape of the transmission frame in the PCB receiving machine, the buffer assembly can adapt to the needs of various PCB receiving machines of different specifications. This design enhances the adaptability and flexibility of the equipment, enabling the buffer assembly to be widely used in various PCB board production lines.

[0027] The body 1 is fixedly connected to a connecting spring 24. One end of the connecting spring 24 is fixedly connected to a rubber buffer plate 23. The rubber buffer plate 23 is fixedly connected to a telescopic rod 22, and one end of the telescopic rod 22 is fixedly connected to the body 1. The telescopic rod 22 passes through the interior of the connecting spring 24. As the main elastic element, the connecting spring 24 can provide effective buffering between the PCB board and the body 1. When the PCB board comes into contact with the rubber buffer plate 23, the connecting spring 24 can absorb and disperse the impact force, reduce the vibration and impact on the PCB board, and thus protect the PCB board from damage.

[0028] The machine body 1 is rotatably connected to a rotating shaft 11, and a spur gear 12 is coaxially fixedly connected to one end of the rotating shaft 11. The spur gear 12 meshes with the rack 2, and an abutment block 10 is fixedly installed on the side of the clamping frame 3.

[0029] The rotating shaft 11 is coaxially and fixedly connected to a ratchet 13, which abuts against a pawl 14. The pawl 14 is rotatably connected to a connecting shaft 15, one end of which is fixedly connected to the top of the machine body 1. The pawl 14 is fixedly connected to a torsion spring 16, and one end of the torsion spring 16 is fixedly connected to the machine body 1. The connecting shaft 15 passes through the interior of the torsion spring 16. Through the interaction between the ratchet 13 and the pawl 14, this design achieves the unidirectional transmission function of the rotating shaft 11. When the rotating shaft 11 rotates in a specific direction... When the ratchet 14 slides smoothly over the tooth surface of the ratchet 13, it allows the rotating shaft 11 to continue rotating. When the rotating shaft 11 attempts to rotate in the opposite direction, the ratchet 14 will engage in the tooth groove of the ratchet 13, preventing it from moving in the opposite direction. This one-way transmission characteristic can improve the stability and accuracy of the movement direction of the rack 2 and limit it. At the same time, after the ratchet 14 contacts its contact with the ratchet 13, it can rotate the rotating shaft 11 in the opposite direction to adjust the length of the rack 2, so that the buffer assembly can adapt to the transfer frame of different PCB board receiving machines.

[0030] Among them, the clamping frame 3 is L-shaped as a whole, and the clamping frame 3 has a slot.

[0031] There are four abutment blocks 10, and every two abutment blocks 10 form a group.

[0032] The other end of the rotating shaft 11 is provided with a knob for rotating the rotating shaft 11.

[0033] Working principle: In use, the entire device is first placed on the transfer frame of the plate take-up machine. Then, by rotating the rotating shaft 11, the spur gear 12, which is fixedly connected to it on the same axis, is rotated. This rotation drives the two racks 2 meshing with the spur gear 12 to retract into the body 1. During the retraction of the racks 2, they drive the clamping frames 3 connected to their ends to move to both sides of the transfer frame. Finally, the clamping frames 3 abut against both sides of the transfer frame, thereby initially fixing the buffer assembly. Next, by rotating the output shaft of the rotating motor 5, the rotating rod 6 and the rotating rod 7 are extended. This extension pushes the movable block 8, which is rotatably connected to one end of the rotating rod 7, forward along a preset trajectory. The clamping block 9, which is fixedly connected to the movable block 8, then clamps the side of the transfer frame. Under the combined action of the two sets of such clamping components, the buffer assembly can be effectively installed on the transfer frame of the plate take-up machine.

[0034] Meanwhile, when the buffer assembly is installed on the transfer rack, the cylinder 17 begins to extend and retract when a PCB board is transferred, causing the two connecting rods 18 at its ends to retract inward. This retraction action causes the sliding block 19 at the end of the connecting rod 18 to move along the trajectory of the fixed track 20 toward the center of the machine body 1. As the sliding block 19 moves, the guide plate 21 connected to its bottom clamps inward. In this way, the transferred PCB board is limited and guided to ensure that it is transferred in a centered position. The PCB board also abuts against the connecting spring 24 in the assembly for buffering. This design facilitates the quick removal and stacking of the PCB board later.
