It mainly consists of pads, vias, mounting holes, wires, components, connectors, filler, and electrical boundaries, and is used to support and connect electronic components, making circuits miniaturized and intuitive.
[0003] During the processing of circuit boards, conveyor belts are often used to transport the circuit boards, and then the circuit boards are manually placed on the workbench for processing, monitoring, or installation of various components. However, this method of manually placing the circuit boards on the workbench is not only physically demanding for the workers, but also prone to unstable handling that could damage the circuit boards. Therefore, we need a feeding device for circuit board processing. Utility Model Content

[0013] Beneficial effects
[0014] This utility model provides a feeding device for circuit board processing, which has the following advantages:
[0015] 1. This circuit board processing loading equipment uses a belt conveyor and board limiting seat to transport circuit boards to a position below the loading tray. An electric telescopic rod extends, and a fan operates in the forward direction to expel air from inside the enclosure through ducts and pipes, creating a negative pressure environment inside the enclosure. The circuit boards are then held in place by a rubber plate. Once fixed, the electric telescopic rod retracts, removing the circuit board from the board limiting seat. As the loading tray rotates, when the board holding mechanism is above the worktable, the electric telescopic rod extends, and the fan rotates in the reverse direction, placing the circuit board on the worktable surface. This completes the circuit board loading process. Compared to manual loading, this method is not only more time-saving and labor-saving, but also reduces the risk of circuit boards falling and getting damaged.
[0016] 2. The circuit board processing feeding equipment is equipped with a first laser sensor, a second laser sensor, and a laser emitter. The first laser sensor receives the laser signal emitted by the laser emitter, which facilitates the alignment of the board limiting seat with the board fixing mechanism. The second laser sensor receives the laser signal emitted by the laser emitter, which facilitates the alignment of the board fixing mechanism with the worktable. Attached Figure Description

[0022] 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.
[0023] Please see Figure 1-4This utility model provides a technical solution: a circuit board processing feeding device, including a workbench 1, a belt conveyor mechanism 2, and two support plates 3. The belt conveyor mechanism 2 is located behind the workbench 1, and multiple board limiting seats 4 are fixedly connected at equal intervals on the surface of the belt conveyor mechanism 2. A feeding tray 5 is rotatably connected between the two support plates 3. A servo motor for driving the feeding tray 5 to rotate is provided on the side of the support plate 3, and the feeding tray 5 is located directly above the belt conveyor mechanism 2. The inner side of the feeding tray 5 is arranged in a circular array. Four support rods 6 are fixedly connected. Each support rod 6 has a connecting seat 7 rotatably connected to its outer surface. Each connecting seat 7 has an electric telescopic rod 8 fixedly connected to its lower surface. Each electric telescopic rod 8 has a plate holding mechanism 9 fixedly connected to its lower end. The plate holding mechanism 9 includes a cover 10, a rubber sheet 11, a fan 12, an air duct 13, and an air pipe 14. The cover 10 is fixedly connected to the lower end of the electric telescopic rod 8. The rubber sheet 11 is fixedly connected to the lower opening of the cover 10. The fan 12 is fixedly connected to the inner wall of the cover 10. 2. Specifically, a forward and reverse rotary fan 12 is used. An air pipe 14 is fixedly connected to the surface of the cover 10. One end of the air pipe 13 is connected to the output end of the fan 12, and the other end of the air pipe 13 is connected to the air pipe 14. Through the belt conveyor mechanism 2 and the board limiting seat 4, the circuit board can be transported to the bottom of the loading tray 5. The electric telescopic rod 8 is extended, and the fan 12 works in the forward direction to discharge the air inside the cover 10 through the air pipe 13 and the air pipe 14, so that the inside of the cover 10 is in a negative pressure state. The circuit board can be fixed by the rubber plate 11 adsorbing it. After the circuit board is fixed, the circuit board can be moved out of the board limiting seat 4 by the retraction of the electric telescopic rod 8. As the loading tray 5 rotates, when the board fixing mechanism 9 is above the worktable 1, the electric telescopic rod 8 is extended and the fan 12 is controlled to rotate in the reverse direction, so that the circuit board can be placed on the surface of the worktable 1, thus completing the board loading work. Compared with manual loading, it is not only more time-saving and labor-saving, but also less likely to cause the circuit board to fall and be damaged.
[0024] The inner wall of the air tube 14 is equipped with a solenoid valve 15. By setting the solenoid valve 15, when the inside of the cover 10 is in a negative pressure state, the solenoid valve 15 can be closed to effectively prevent outside air from entering the inside of the cover 10 through the air tube 14, so that the rubber plate 11 can stably adsorb the circuit board.
[0025] Both sides of the cover 10 are fixedly connected with L-shaped clips 16, and the lower inner side of the L-shaped clips 16 is chamfered. By setting the L-shaped clips 16, the two ends of the circuit board can be clipped together, thereby further improving the fixing effect of the circuit board.
[0026] A first laser sensor 17 is fixedly installed on the side of the plate limiting seat 4, and a second laser sensor 18 is fixedly installed on the surface of the worktable 1. A laser emitter 19 is fixedly installed on the side of the cover 10 through a side support plate. By setting the first laser sensor 17, the second laser sensor 18 and the laser emitter 19, the first laser sensor 17 can receive the laser signal emitted by the laser emitter 19, which can facilitate the alignment of the plate limiting seat 4 with the plate fixing mechanism 9. The second laser sensor 18 can receive the laser signal emitted by the laser emitter 19, which can facilitate the alignment of the plate fixing mechanism 9 with the worktable 1.
[0027] A crossbeam arm 20 is slidably connected to the surface of the workbench 1. The end of the crossbeam arm 20 away from the workbench 1 is fixedly connected to the support plate 3. A stud 21 is fixedly connected to the surface of the workbench 1, and the stud 21 passes through the strip groove 22 on the surface of the crossbeam arm 20. A locking nut 23 is threadedly connected to the outer surface of the stud 21. By setting the crossbeam arm 20, the stud 21 and the locking nut 23, the distance between the feeding tray 5 and the workbench 1 can be adjusted by sliding the stud 21 in the strip groove 22. By tightening the locking nut 23, the feeding tray 5 and the workbench 1 can be fixed relative to each other.
[0028] Working principle: When the circuit board processing loading equipment is in use, the circuit boards produced on the production line are first placed inside the board limiting seat 4. Then, the belt conveyor mechanism 2 transports the circuit boards to the bottom of the loading tray 5. When the first laser sensor 17 detects the signal emitted by the laser emitter 19, the electric telescopic rod 8 is extended, which drives the board fixing mechanism 9 to move downward. When the rubber plate 11 is attached to the surface of the circuit board, the fan 12 works in the forward direction. The forward operation of the fan 12 exhausts the air inside the cover 10 through the air duct 13 and air pipe 14, which can make the inside of the cover 10 a negative pressure state. The circuit board is fixed by the rubber plate 11 adsorbing it. After the board is fixed, the electric telescopic rod 8 can be retracted to move the circuit board out of the board limiting seat 4. Under the action of gravity, the board fixing mechanism 9 always faces downward. As the feeding tray 5 rotates, when the board fixing mechanism 9 is above the worktable 1, the second laser sensor 18 monitors the signal emitted by the laser emitter 19, and the electric telescopic rod 8 is extended and the fan 12 is controlled to rotate in the opposite direction. This allows outside air to enter the cover 10 through the air pipe 14 and the air duct 13. After the rubber plate 11 expands outward, the circuit board can be placed on the surface of the worktable 1, thus completing the board feeding work. Compared with manual feeding, it is not only more time-saving and labor-saving, but also less likely to cause the circuit board to fall and be damaged.
[0029] The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
