[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model involves installing the feeding device on an automated production line for circuit board assembly. A displacement sensor is installed above the component along the component's transport path, and a bending mechanism is installed on one side of the component. During transport, a cylinder is activated, moving the connecting seat, which in turn moves the movable frame, which in turn moves the bending roller. The bending roller contacts one side of the component. Since the pins at the bottom of the component are fixed to the transport structure, pressure is applied to the component by the bending roller, causing it to tilt to one side and bend the pins at a 90-degree angle, thus achieving rapid bending of the component.

[0017] 2. This utility model uses a spring to support the limiting post. One side of the limiting post is connected to the movable frame. When the movable frame is pressed, it drives the spring to compress, which at the same time buffers the pressure generated by the bending roller contacting the components. This reduces damage to the lead wire during bending and prevents the lead wire from breaking. This device effectively reduces manual operation steps, lowers labor costs, and reduces the scrap rate caused by poor welding. In addition, the integrated device structure is relatively simple, reducing the equipment's footprint and maintenance costs. It reduces the production cost of circuit board assembly from multiple aspects and improves the economic benefits of enterprises. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0026] Please see Figure 1-5 This utility model is a component feeding device for circuit board assembly, including a mounting plate 1, a housing 2 fixedly connected to the top of the mounting plate 1, a bending mechanism 3 fixedly connected to the inner wall of the housing 2, a mounting seat 4 on one side of the top of the housing 2, a displacement sensor 5 on one side of the mounting seat 4, the bending mechanism 3 including a fixing plate 6, one side of the fixing plate 6 fixedly connected to the inner wall of the housing 2, a cylinder 7 fixedly connected to the other side of the fixing plate 6, a connecting seat 8 fixedly connected to one side of the cylinder 7, mounting holes 9 are provided at the front and rear ends of one side of the connecting seat 8, a movable frame 10 is provided on one side of the connecting seat 8, a bending roller 11 is fixedly connected to one side of the movable frame 10, a limit post 12 is fixedly connected to the front and rear ends of one side of the movable frame 10, one side of the limit post 12 extends into the inner cavity of the mounting hole 9, a spring 13 is fixedly connected to one side of the limit post 12, and the other side of the spring 13 is fixedly connected to the inner wall of the mounting hole 9.

[0027] Specifically: Mounting plate 1 is used to install on the production line of circuit board assembly. It is small in size and has a small installation area, which can improve the convenience of installation. The bending mechanism 3 is installed inside the housing 2. The housing 2 protects the bending mechanism 3 and avoids interference with other wiring parts during the movement of cylinder 7, thus improving the safety of production. The displacement sensor 5 emits a laser beam to the surface of the object being measured and then receives the reflected light. It calculates the position information of the object surface based on the time of the laser round trip or the angle change of the reflected light. It can detect the perpendicularity of the component to be bent and will not affect the subsequent bending effect due to the tilting phenomenon of the component during the transportation process. By setting a buffer structure of spring 13 between the movable frame 10 and the connecting seat 8, the pressure generated when the bending roller 11 contacts the component can be reduced, which can reduce the damage to the pins caused by the pressure. Example 2

[0028] Please see Figure 1-5 Based on Embodiment 1, the bottom of the displacement sensor 5 extends to one side of the bending roller 11. The displacement sensor 5 is a laser displacement sensor. A mounting groove 14 is provided on one side of the mounting base 4. The displacement sensor 5 is set in the inner cavity of the mounting groove 14 and is fastened by bolts. An adjustment frame 15 is fixedly connected to the top of the housing 2. A groove is provided on one side of the adjustment frame 15. One side of the mounting base 4 is threadedly connected to the adjustment frame 15 by bolts. Limiting rods 16 are fixedly connected to the front and rear ends of one side of the movable frame 10. Limiting grooves 17 that cooperate with the limiting rods 16 are provided on the top and bottom of one side of the connecting base 8. Fasteners 18 are threadedly connected to the four corners of the top of the mounting plate 1. Gaskets are provided at the connection between the fasteners 18 and the mounting plate 1. Connecting plates 19 are fixedly connected to both sides of the housing 2. The top of the connecting plates 19 is fixedly connected to the mounting plate 1 by bolts. The surface of the bending roller 11 is set as a concave arc structure to match the arc surface of the component.

[0029] Specifically: the displacement sensor 5 adopts a laser displacement sensor, which can accurately obtain the surface position information of the component to determine the perpendicularity. It has a fast measurement speed and can detect multiple components in a short time. It is suitable for high-speed circuit board assembly production lines. The displacement sensor 5 is installed inside the mounting slot 14 to ensure the stability of the displacement sensor 5 installation. Through the cooperation of the adjusting bracket 15 and the slot, the mounting base 4 can be flexibly fixed. It also has the purpose of height adjustment to facilitate the debugging of the displacement sensor 5. One end of the limiting rod 16 extends into the inner cavity of the limiting slot 17 to limit the movable frame 10 and ensure the stability of the movable frame 10 when it is under pressure. The mounting plate 1 is connected to the production line through fasteners 18 and gaskets to ensure the stability of the mounting plate 1 installation. The connecting plate 19 is used to install the housing 2 on the top of the mounting plate 1 to ensure the positioning effect of the housing 2.

[0030] The working principle of this utility model is as follows: The feeding device is installed on an automated production line for circuit board assembly. A displacement sensor 5 is installed above the component along the component's transport path, and a bending mechanism 3 is installed on one side of the component. During transport, the cylinder 7 is activated, causing the connecting seat 8 to move. The connecting seat 8 then moves the movable frame 10, which in turn moves the bending roller 11. The bending roller 11 contacts one side of the component. Since the pins at the bottom of the component are fixed to the transport structure, pressure is applied to the component by the bending roller 11, causing the component to tilt to one side and bend the pins at a 90-degree angle. This achieves rapid bending of the component. The purpose is to support the limiting post 12 with spring 13. One side of the limiting post 12 is connected to the movable frame 10. When the movable frame 10 is pressed, it drives the spring 13 to compress. At the same time, it can buffer the pressure generated by the bending roller 11 contacting the component, thereby reducing the damage to the lead wire during bending and avoiding the breakage of the lead wire. The displacement sensor 5 adopts a laser displacement sensor, which can accurately obtain the surface position information of the component to determine the perpendicularity. The measurement speed is fast and multiple components can be detected in a short time. This device reduces the risk of breakage that is easy to occur when manually bending the components before assembly, and improves the yield rate.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to specific implementation methods. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
