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.

[0022] Please see Figure 1-3 This embodiment provides a technical solution: a feeding machine for circuit board production, including a frame 1, characterized in that: it also includes a first discharge mechanism 2 and a second discharge mechanism 5, a microcontroller 7 is provided on the right front side of the frame 1, the input end of the microcontroller 7 is electrically connected to an external power supply, a first conveyor 3 is provided on the upper left side inside the frame 1, a second conveyor 4 is provided on the lower left side inside the frame 1, and the input ends of the first conveyor 3 and the second conveyor 4 are respectively electrically connected to the output end of the microcontroller 7;

[0023] First discharge mechanism 2: Located inside the right side of the frame 1, the first discharge mechanism 2 includes a mounting chamber 21, a lead screw 22, guide rods 23, a bellows 24, a threaded cylinder 25, a first sleeve 26, and a height adjustment frame 27. The mounting chambers 21 are respectively located on the right side of the front side wall and the right side of the rear side wall of the frame 1. Guide rods 23 are symmetrically fixedly connected between the upper and lower inner walls of the two mounting chambers 21. A lead screw 22 is rotatably connected between the upper and lower inner walls of the rear mounting chamber 21. The outer arc surfaces of the four guide rods 23 are slidably connected to the first sleeves 26, and the outer arc surfaces of the four first sleeves 26 are fixedly connected to... A height adjustment frame 27 is provided, with a threaded cylinder 25 fixedly connected to the middle of its rear side. The internal thread of the threaded cylinder 25 is threadedly connected to the external thread of the lead screw 22. Bellows 24 are fixedly connected to the upper and lower sides of the threaded cylinder 25, respectively. The ends of the two bellows 24 are fixedly connected to the inner wall of the rear mounting chamber 21. The bellows 24 are sleeved on the outside of the lead screw 22. The first discharge mechanism 2 also includes a reciprocating conveyor 28 and a height adjustment motor 29. The reciprocating conveyor 28 is located inside the height adjustment frame 27. The height adjustment motor 29 is located on the right rear side of the upper surface of the frame 1. The output shaft of motor 29 is fixedly connected to the upper end of lead screw 22. The input ends of reciprocating conveyor 28 and height adjustment motor 29 are electrically connected to the output end of microcontroller 7. The system also includes a plate holder 6, which is placed on top of reciprocating conveyor 28. A support frame 8 is provided on the upper right side of the frame 1. When using this feeding machine, circuit boards can be inserted sequentially into the placement slots inside the plate holder 6 until the plate holder 6 is fully installed. Then, the plate holder 6 can be placed onto the conveyor belt of the second conveyor 4. The operation of microcontroller 7, the second conveyor 4, and the reciprocating conveyor 28 can then be controlled. The conveyor belts of the conveyor 4 and the reciprocating conveyor 28 operate synchronously in the same direction. At this time, the plate holder 6 on the second conveyor 4 conveys to the right until it moves to the upper side of the height adjustment frame 27. Then, the microcontroller 7 and the reduction motor 57 can be controlled to operate. The output shaft of the reduction motor 57 rotates a specified number of times, which causes the lead screw 22 to rotate a specified number of times, thereby driving the threaded cylinder 25 to move upward to a specified height. During the movement of the height adjustment frame 27, the bellows 24 will also extend and retract synchronously. The bellows 24 always seals the lead screw 22 to prevent external dirt from contaminating the external thread surface of the lead screw 22.

[0024] The second discharge mechanism 5 includes a top material frame 51, a second sleeve 52, a top rod 53, a top block 54, a first connecting rod 55, and a second connecting rod 56. The top material frame 51 is located on the upper left side inside the frame 1. The right side wall of the top material frame 51 is provided with the second sleeve 52. The top rod 53 is slidably connected inside the second sleeve 52. The right end of the top rod 53 is provided with the top block 54. The left end of the top rod 53 is rotatably connected to the first connecting rod 55. The end of the first connecting rod 55 is rotatably connected to the second connecting rod 56. The second discharge mechanism 5 also includes a reduction motor 57, which is located on the left side of the upper surface of the top material frame 51. The output shaft of the reduction motor 57 is fixedly connected to the end of the second connecting rod 56. The input end of the reduction motor 57 is electrically connected to the output end of the microcontroller 7. The microcontroller 7 can then be controlled to operate the reduction motor 57. The output shaft of the reduction motor 57 rotates one revolution, thereby causing the end of the second connecting rod 56 to rotate around the reduction motor 57. The output shaft of the high-speed motor 57 rotates along its central axis. When the end of the second connecting rod 56 reaches the rightmost position, it pushes the push rod 53 to the right via the first connecting rod 55, causing the push block 54 to move to the rightmost position. This pushes the circuit board in the placement slot out to the right, and then, guided by the support frame 8, pushes the circuit board out and transfers it to the outside. At this point, the circuit boards inside the placement frame 6 can be pushed out to the right in sequence according to the above steps, completing the intermittent and continuous material conveying operation. After all the circuit boards inside the placement frame 6 have been pushed out, the height adjustment frame 27 will continue to move upward until it is at the same height as the first conveyor 3. At this point, the microcontroller 7 can be controlled to operate the first conveyor 3 and the reciprocating conveyor 28 simultaneously, with the first conveyor 3 and the reciprocating conveyor 28 in opposite directions, conveying the placement frame 6 out. Then, the height adjustment frame 27 is reset, and the above steps are repeated.

[0025] The working principle of the circuit board feeding machine provided by this utility model is as follows: When the feeding machine is needed, the circuit boards can be inserted into the placement slots inside the board holder 6 in sequence until the board holder 6 is fully installed. Then, the board holder 6 can be placed on the conveyor belt of the second conveyor 4. Then, the microcontroller 7, the second conveyor 4, and the reciprocating conveyor 28 can be controlled to operate. The conveyor belts of the second conveyor 4 and the reciprocating conveyor 28 operate synchronously in the same direction. At this time, the board holder 6 on the second conveyor 4 is transported to the right until it moves to the upper side of the height adjustment frame 27. Then, the microcontroller 7 and the reduction motor 57 can be controlled to operate. The output shaft of the reduction motor 57 rotates a specified number of times, which causes the lead screw 22 to rotate a specified number of times, thereby driving the threaded cylinder 25 to move upward to a specified height. Then, the microcontroller 7 and the reduction motor 57 can be controlled to operate. The output shaft of the reduction motor 57 rotates one revolution, thereby causing the lead screw 22 to rotate a specified number of times, thereby driving the threaded cylinder 25 to move upward to a specified height. The end of the second link 56 rotates around the central axis of the output shaft of the reduction motor 57. When the end of the second link 56 rotates to the rightmost end, it will push the push rod 53 to the right through the first link 55, causing the push block 54 to move to the rightmost right side, pushing the circuit board in the placement slot out to the right. Then, guided by the support frame 8, the circuit board is pushed out and transferred to the outside. At this time, the above steps can be followed to push the circuit board inside the plate holder 6 out to the right in sequence, completing the intermittent and uninterrupted material conveying operation until all the circuit boards inside the plate holder 6 are pushed out. Then, the height adjustment frame 27 will continue to move upward until the height adjustment frame 27 is at the same height as the first conveyor 3. At this time, the microcontroller 7 can be controlled to operate the first conveyor 3 and the reciprocating conveyor 28 at the same time. At this time, the conveying directions of the first conveyor 3 and the reciprocating conveyor 28 are opposite, conveying the plate holder 6 out, and then the height adjustment frame 27 is reset. The above steps can be repeated.

[0026] It is worth noting that the core chip of the single-chip microcomputer 7 disclosed in the above embodiments is a single-chip microcomputer, specifically the STM32F103C8T6. The first conveyor 3, the second conveyor 4, the reciprocating conveyor 28, the height adjustment motor 29, and the geared motor 57 can be freely configured according to the actual application scenario. The first conveyor 3, the second conveyor 4, and the reciprocating conveyor 28 need to be customized with electric conveyor belts of specified specifications according to requirements. It is recommended that the height adjustment motor 29 be a stepper motor of model 57, and the geared motor 57 be a geared motor of model 61K180GU-S3. The single-chip microcomputer 7 controls the operation of the first conveyor 3, the second conveyor 4, the reciprocating conveyor 28, the height adjustment motor 29, and the geared motor 57 using methods commonly used in the prior art.
