[0030] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0031] Embodiment 1

[0032] like Figure 1-Figure 4 As shown, in this embodiment, a circuit board conveying device for an insertion machine is provided, including a bracket 1, which is responsible for carrying and installing other components of the conveying device. These components are all fixed on the bracket 1, and the bracket 1 is installed horizontally and is built into the machine of the insertion machine, which not only optimizes space utilization but also realizes the conveying function. The bracket 1 is installed with a first support plate 2 and a second support plate 3, and the first support plate 2 and the second support plate 3 can be arranged horizontally on the bracket 1. The first support plate 2 and the second support plate 3 are respectively provided with a first push channel 201 and a second push channel 301, which are arranged inside the two opposite sides of the first support plate 2 and the second support plate 3. The first push channel 201 and the second push channel 301 are arranged inside the two opposite sides of the first support plate 2 and the second support plate 3. The second pushing channel 301 forms a conveying channel for the movement of the circuit board. The two side edges of the circuit board extend into the internal space of the first pushing channel 201 and the second pushing channel 301 respectively. Subsequently, these circuit boards are driven by the built-in pushing units in these channels and move along a preset path. The first slide 2011 and the second slide 2012 are provided with openings on the side away from the medium channel 2013. The circuit board can enter the interior of the first slide 2011 from the opening of the first slide 2011, and can slide away from the second slide 2012 from the opening of the second slide 2012.

[0033] The first and second push units for pushing the circuit board to move are installed inside the first support plate 2 and the second support plate 3, respectively. The first and second push units act on the two sides of the circuit board respectively to ensure that the circuit board is supported in a balanced manner during the movement. The first and second push units maintain the same pushing speed. This synchronization design ensures that the circuit board can move smoothly.

[0034] The second support plate 301 is fixed on the bracket 1, and the second support plate 3 is rotatably mounted on the bracket 1. The second support plate 3 is rotatably mounted on the bracket 1 through a hinge shaft. When the second support plate 3 rotates, the second push channel 301 can follow the second support plate 3 to tilt. The second support plate 3 is rotatably mounted on the bracket 1 located at the bottom thereof through a corresponding rotating shaft. Since the second push channel 301 is opened inside the side of the second support plate 3, the second push channel 301 is opened on a side away from the corresponding rotating shaft. The first push channel 201 is provided with a first slide 2011 and a second slide 2012 inside. There is a height difference between the first slide 2011 and the second slide 2012. The inclination angle of the circuit board is closely related to the arrangement of the two slides (the first slide 2011 and the second slide 2012). Specifically, when the first support plate 2 maintains a horizontal state, the inclination angle of the circuit board just matches the inclination angle of the second slide 2012, so that the side of the circuit board can be smoothly embedded in the second slide 2012. When one end of the first support plate 2 tilts up, the inclination angle of the circuit board is automatically adjusted to be consistent with the inclination angle of the first slide 2011, and at this time, one end of the circuit board will be embedded in the first slide 2011. This process ensures that the circuit board can be firmly and accurately aligned with and embedded in the corresponding slide in different states. A medium channel 2013 is provided between the first slide 2011 and the second slide 2012. The first slide 2011 and the second slide 2012 extend to the inside of the medium channel 2013 respectively. The circuit board can be transferred from the first slide 2011 to the inside of the second slide 2012 through the medium channel 2013. The first slide 2011 and the second slide 2012 are both linear channels. One end of the first slide 2011 and the second slide 2012 extending to the inside of the medium channel 2013 has an overlapping portion in the projection perpendicular to the surface of the first support plate 2, and the overlapping portion coincides with the medium channel 2013.

[0035] A plurality of pressing plates 4 are movably mounted on the first support plate 2. The pressing plates 4 can push one end of the circuit board to move in the medium channel 2013. In the working state, one end of the circuit board extends to the inside of the first push channel 201, and the other end enters the second push channel 301. At the same time, the second support plate 3 and the circuit board are both naturally tilted. In this state, the circuit board and the first slide 2011 are in the same plane. When an external force is applied, especially through the pressing action of the pressing plate 4, the external force will generate a downward pressure on the circuit board, thereby causing the circuit board and the second support plate 3 to rotate together around the rotating shaft located on one side of the second support plate 3. As the rotation proceeds, the circuit board finally reaches a horizontal state. In this state, the circuit board and the second slide 2012 are in the same plane, providing conditions for the circuit board to move from the medium channel 2013 to the second slide 2012.

[0036] Embodiment 2

[0037] like Figure 1-Figure 8 As shown, based on the first embodiment, this embodiment provides a method for moving and positioning the circuit board inside the pushing channel, which is as follows:

[0038] A plurality of rotatable push rollers are installed at the upper and lower ends of the first slide 2011 and the second slide 2012, and a plurality of rotatable push rollers are also installed at the upper end of the medium channel 2013. The push rollers at the upper end of the first slide 2011 and the push rollers at the upper end of the medium channel 2013 are on the same straight line, and the push rollers are evenly arranged along the transmission direction. When the push rollers inside the first slide 2011 rotate, they can drive the circuit board inside the first channel to move toward the direction of the medium channel 2013.

[0039] A through groove is provided at the bottom of the medium channel 2013, and a connecting plate 6 is fixed inside the through groove. A plurality of push rollers that can rotate are rotatably installed on the surface of the connecting plate 6. A plurality of slide bars 7 are slidably installed inside the connecting plate 6 through springs. The upper end of the slide bar 7 extends to the inside of the medium channel 2013, and a steel ball is rotatably installed at one end of the slide bar 7 extending to the inside of the medium channel 2013. In the initial state, the steel ball and the push roller at the bottom of the first slide 2011 are in the same plane. Driven by the upward potential energy given by the spring, the slide bar 7 ensures the initial state of the slide system. This potential energy not only constructs a channel for the circuit board to move smoothly between the first slide 2011 and the medium channel 2013, but also enables the circuit board to move forward along this path. When the circuit board enters the inside of the medium channel 2013, the pressing plate 4 applies a downward pressure to the circuit board. This pressure is sufficient to overcome the supporting force provided by the slide bar 7 and push the pressing plate 4 to slide downward along a predetermined trajectory.

[0040] As the pressing plate 4 slides downward, the circuit board is safely guided to the bottom of the medium channel 2013 and fits tightly onto the push roller located there. At this time, the push roller uses its own rotational power to smoothly push the circuit board into the second slideway 2012, thereby completing the entire transmission process of the circuit board from the initial position to the target position.

[0041] The side edge of the medium channel 2013 close to the second slide 2012 is the positioning surface of the circuit board. After the circuit board moves from the first slide 2011 to the inside of the medium channel 2013, the circuit board will rest on this positioning surface to complete the positioning of the circuit board and ensure that the circuit board can slide down smoothly.

[0042] Embodiment 3

[0043] like Figure 1-Figure 8 As shown, based on the first and second embodiments, this embodiment provides a method for installing the pressing plate 4, which is as follows:

[0044] A driving shaft 5 is rotatably mounted on the bracket 1. The driving shaft 5 is arranged on one side of the first support plate 2 along the length direction of the first support plate 2. One ends of multiple pressure plates 4 are fixedly mounted on the driving shaft 5. A driving device for driving the driving shaft 5 to rotate is fixed on the bracket 1. The driving device can be a motor or other components that can drive the driving shaft 5 to rotate a certain angle. When the driving device drives the pressure plate 4 to rotate toward the circuit board, pressure can be applied to the circuit board, causing the circuit board to rotate downward inside the medium channel 2013.

[0045] The pressing plate 4 is a split structure, and the pressing plate 4 includes a fixed plate fixedly connected to the driving shaft 5, and a movable plate movably connected to the fixed plate. The movable plate and the fixed plate are connected by bolts, and the position of the movable plate on the fixed plate can be adjusted, so that the movable plate can be flexibly adjusted, and the end of the movable plate extends to the outside of the first pushing channel 201 and is arc-shaped. The end of the arc is in contact with the circuit board. The arc shape can more easily protect the circuit board and reduce the probability of scratching the circuit board.

[0046] An arc plate 9 is installed at the bottom of the second support plate 3, and an arc groove adapted to the arc plate 9 is provided inside the bracket 1. One end of the arc plate 9 is adapted to the arc groove and slidably installed inside the arc groove. An elastic body acting on the end of the arc plate 9 is installed inside the arc groove. The arc plate 9 and the arc groove both take the hinge axis of rotation of the second support plate 3 as the center of the circle to ensure that the second support plate 3 can rotate smoothly. Under the action of the elastic body, the second support plate 3 is usually in a tilted state, and the extension direction of the second push channel 301 on the second support plate 3 coincides with the first slide 2011 in the first push channel 201, ensuring that the circuit board can smoothly enter the first push channel 201 and the second push channel 301.

[0047] A conveyor belt 8 is installed on the second support plate 3, and the conveyor belt 8 is attached to the bottom surface of the second pushing channel 301 for transmission. A plurality of pushing rollers are rotatably installed on the upper end of the second pushing channel 301, and one side of the circuit board is arranged between the conveyor belt 8 and the pushing rollers, and the conveyor belt 8 drives the circuit board to move inside the second pushing channel 301.

[0048] Working principle:

[0049] This conveying device ensures the smooth flow and fixation of circuit boards in the production process. First, the circuit board from the previous process is precisely aligned to the conveying path formed by the inclined second support plate 3 at the entrance of this device through a dedicated conveying mechanism to achieve seamless access. Then, the circuit board enters the interior of this device and is smoothly pushed into the medium channel 2013 under the joint action of multiple push rollers and processed by the insertion machine.

[0050] In the medium channel 2013, the circuit board will be against the positioning surface, and this process ensures the accurate position of the circuit board, laying a foundation for subsequent operations. Then, the pressing plate 4 applies a proper amount of pressure to the circuit board to enhance the stability of the circuit board.

[0051] After completing the above positioning and calibration steps, the circuit board is again accurately pushed to the conveying mechanism at the discharge end along the conveying path formed by the second support plate 3 in the horizontal state with the help of the force of the push roller.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
