Description

Technical Field

[0001] This utility model belongs to the technical field of PCB board processing, specifically relating to a flipping feeding mechanism. Background Technology

[0002] To prevent oxidation of the bare copper surface of the PCB board and maintain its solderability, the PCB board needs to be tin-plated. Since the PCB board is placed horizontally during the loading process, it needs to be adjusted to a vertical position during tin plating to ensure uniform tin plating and reduce space occupation. Therefore, in automated loading equipment, the PCB board needs to be flipped for loading. However, the existing flipping loading mechanism cannot accurately position the clamping position of PCB boards of different sizes when clamping and flipping them, resulting in unstable clamping and the risk of the PCB board falling. This not only leads to damage to the PCB board, but also seriously affects production efficiency. Utility Model Content

The loading platform is also provided with a limiting component two at the end along the conveying direction. The limiting component two includes a baffle, a crossbeam and a driving component one. The crossbeam is located on the loading platform. The driving component one is fixedly connected to the crossbeam. The output shaft of the driving component one is connected to the baffle. The driving component one drives the baffle to move to adjust the position of the PCB board.

[0005] Furthermore, the loading platform is also provided with several rotating shafts that rotate along the Y-axis, and several rollers are provided on the rotating shafts.

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figure 1-4 , Figure 6 As shown, this utility model provides a flipping feeding mechanism, including a frame 1, a feeding platform 2 and a flipping component 3 on the frame 1, the flipping component 3 being located on the side of the feeding platform 2, the feeding platform 2 having feeding notches 21 adapted to the flipping component 3 on both sides along the X-axis direction, and the flipping component 3 rotating within the feeding notches 21. The flipping component 3 is equipped with two clamps 33, which are used to clamp the PCB board located on the loading platform 2. The number of clamps 33 is set to two, so that the clamping force is stronger and more stable, thereby reducing the risk of the PCB board falling during loading and making the loading process smoother.

[0032] Specifically, the loading platform 2 is also provided with a plurality of rotating shafts 22 that rotate along the Y-axis. The rotating shafts 22 are provided with a plurality of rollers 221. One end of each rotating shaft 22 is fixedly connected to a pulley 222. The frame 1 is also provided with a driving component 7 12 located below the loading notch 21. The driving component 7 12 is connected to each of the pulleys 222 by belt drive to ensure the synchronicity of the rotation of each rotating shaft 22 and the rollers 221. When the PCB board is placed on the rollers 221, the PCB board will move forward as the rollers 221 rotate. The loading platform 2 is further provided with a limiting component 2 5 at its end along the conveying direction. The limiting component 2 5 includes a baffle 51, a crossbeam 52, and a driving component 53. The crossbeam 52 is located on the loading platform 2, and the driving component 53 is fixedly connected to the crossbeam 52. The output shaft of the driving component 53 is connected to the baffle 51, and the driving component 53 drives the baffle 51 to move in order to adjust the position of the PCB board. During loading, the baffle 51 can be pre-moved to a suitable position according to the size of the PCB board, or during the PCB board conveying process, the baffle 51 can be moved by the drive component 53, so that the PCB board is blocked by the baffle 51 and cannot continue to be conveyed forward, thereby making the position of the PCB board correspond to the position of the loading notch 21. Thus, when the present invention flips and loads PCB boards of different sizes, only the position of the baffle 51 needs to be adjusted to ensure that the final position of the PCB boards of different sizes is kept at the loading notch 21 when they are conveyed on the roller 221. This makes it easier for the clamp 33 on the flipping component 3 to accurately position the clamping position of the PCB board, thereby achieving fast and stable clamping; and the adjustment method is more flexible and convenient.

[0033] Furthermore, to ensure that the PCB board does not pass under the baffle 51, the baffle 51 extends below the upper surface of the roller 221. The baffle 51 has a groove 511 to avoid the roller 221. This structure ensures that the PCB board does not pass under the baffle 51, while avoiding interference between the baffle 51 and the roller 221. It can be adjusted at any time during the PCB board conveying process, and the adjustment accuracy is higher.

[0034] Furthermore, such as Figure 3As shown, the loading platform 2 is also provided with slide rails 23 on both sides, and sliders 24 are provided on the slide rails 23. The two ends of the crossbeam 52 are respectively connected to the two sliders 24. The sliders 24 are located on the slide rails 23. One end of one of the slide rails 23 is also provided with a second driving component 25. The second driving component 25 drives the slider 24 to move, thereby driving the crossbeam 52 and the baffle 51 to move as a whole. The baffle 51 can be adjusted by the first driving component 53 and / or the second driving component 25, which greatly improves the flexibility and accuracy of the loading process, ensures that PCBs of different sizes can be accurately positioned and clamped, thereby improving the stability and accuracy of the clamping of the fixture 33, and enabling the flipping component 3 to smoothly and quickly complete the vertical flipping action after clamping the PCB.

[0035] Preferably, the slide rail 23 is also provided with a stretchable cover 26. The cover 26 can cover the slide rail 23 and the slider 24 to prevent dust or other debris from falling on the slide rail 23, increasing sliding resistance or even causing the sliding to be interrupted, thereby affecting the production progress.

[0036] In this embodiment, as Figure 4 As shown, an auxiliary plate 54 is also provided below the crossbeam 52. The output shaft of the drive component 53 is connected to the auxiliary plate 54. The baffle 51 is disposed on the auxiliary plate 54. Therefore, the drive component 53 can synchronously drive the movement of the auxiliary plate 54 and the baffle 51. To prevent the auxiliary plate 54 from shaking at both ends when it moves, a number of guide blocks 521 are screwed sequentially at intervals below the crossbeam 52. A guide post 522 is slidably connected inside the guide block 521. One end of the guide post 522 is connected to the auxiliary plate 54, so that the auxiliary plate 54 is subjected to more balanced force and thus moves more stably.

[0037] Preferably, to achieve automated production of the machine, the auxiliary plate 54 is provided with a second photoelectric sensor 55. In this embodiment, the second photoelectric sensor 55 is a U-shaped photoelectric sensor. When the PCB board is conveyed along the Y-axis and abuts against the baffle 51, the PCB board is just located in the U-shaped groove of the second photoelectric sensor 55. At this time, the second photoelectric sensor 55 sends a signal, and after processing, the pusher assembly 6 will be activated, causing the PCB board to move along the edge of the baffle 51 in the X-axis direction under the drive of the pusher assembly 6, ensuring that the clamp 33 can smoothly and timely clamp the PCB board.

[0038] Furthermore, such as Figure 5 , Figure 6As shown, a pushing assembly 6 is slidably connected within the loading platform 2 at the loading notch 21. The pushing assembly 6 is located below the roller 221. The pushing assembly 6 includes a push rod 61, a sliding member 62, a driving member 63, and a timing belt 64, all perpendicularly arranged to the loading platform 2. The driving member 63 is fixedly connected to the frame 1, and its output shaft is rotatably connected to the timing belt 64. The sliding member 62 is fixedly connected to one side of the timing belt 64. The push rod 61 is mounted on the sliding member 62. When the driving member 63 rotates, it can drive the timing belt 64 to rotate, thereby driving the roller 221 located below the loading platform 2. The sliding member 62 and push rod 61 on the synchronous belt 64 move, wherein the push rod 61 extends to the roller 221. When the PCB board is above the loading notch 21, the sliding member 62 and the push rod 61 move along the X-axis, so that the push rod 61 abuts against the other side of the PCB board and drives the PCB board to move along the X-axis, so as to push the PCB board into the clamp 33 of the flipping component 3 for the clamp 33 to perform precise clamping. This effectively avoids the clamping failure problem caused by the gap or position deviation between the PCB board and the clamp 33, and further improves the reliability and automation of the loading process.

[0039] Furthermore, such as Figure 7 As shown, the loading platform 2 is also equipped with a limiting component 4, which includes a lifting plate 41, a fixed plate 42, and a lifting drive component 43. One side of the fixed plate 42 is connected to the frame 1, and the other side is connected to the lifting drive component 43. The output end of the lifting drive component 43 is connected to the lifting plate 41 to drive the lifting plate 41 to move up and down between two adjacent rotating shafts 22. The lifting plate 41 is used to block the conveying of the next PCB board and avoid interference between the two PCB boards. By setting the lifting plate 41 below the roller 221, the overall structure is not only simple, but also more concise and beautiful. When the user manually adjusts the position of the PCB board or observes the loading situation, the limiting component 4 will not cause any obstruction, making it more convenient to use.

[0040] Preferably, to ensure precise coordination between the lifting of the lifting plate 41 and the conveying of the PCB board, a photoelectric sensor 11 is provided on the frame 1 next to the lifting plate 41. When the PCB board passes the photoelectric sensor 11 along with the roller 221, the output end of the lifting drive 43 will move upward, causing the lifting plate 41 to extend above the roller 221 to block the subsequent continuous conveying of the PCB board.

[0041] Furthermore, such as Figure 8-10As shown, the flipping assembly 3 includes a flipping drive 31, a flipping frame 32, a rotating plate 34, and two bearing seats 35. The bearing seats 35 and the flipping drive 31 are both fixedly connected to the frame 1. The rotating plate 34 is rotatably connected between the two bearing seats 35. The flipping frame 32 is disposed on the rotating plate 34. The output shaft of the flipping drive 31 passes through one of the bearing seats 35 and is connected to the rotating plate 34. By driving the rotating plate 34 to rotate through the flipping drive 31, the rotating plate 34 can drive the flipping frame 32 to rotate synchronously. The flipping frame 32 has two symmetrical flipping arms 321 and a connecting seat 322 connected to the two flipping arms 321. The two clamps 33 are respectively set on the flipping arms 321, and each clamp 33 can perform a clamping action independently. This design makes the flipping assembly 3 more flexible and stable when clamping PCB boards. Correspondingly, there are two feeding notches 21 corresponding to the flipping arms 321. During loading, the flipping frame 32 rotates 90° towards the loading platform 2 under the drive of the flipping drive 31, so that the flipping frame 32 falls into the loading notch 21 and is arranged parallel to the loading platform 2. In this embodiment, the push rod 61 corresponds to the two loading notches 21 respectively and there are two of them, which can make the movement of the PCB board smoother and more balanced. After the clamp 33 clamps the PCB board, the flipping drive 31 drives the rotating plate 34 to rotate in the opposite direction, so that the rotating plate 34 and the flipping frame 32 holding the PCB board are vertically flipped by 90°, realizing the vertical flipping loading of the PCB board.

[0042] Furthermore, such as Figure 9 As shown, the clamp 33 includes a driving component 331, a connecting rod 332, a movable clamping plate 333, and a fixed clamping plate 334. The driving component 331 is fixed to the flipping arm 321. One end of the connecting rod 332 is connected to the output end of the driving component 331, and the other end is connected to the movable clamping plate 333. The movable clamping plate 333 is located at the top of the flipping arm 321. Side plates 3212 extend from both sides of the top of the flipping arm 321. The movable clamping plate 333 is rotatably connected between the two side plates 3212 via a rotating shaft. The fixed clamping plate 334 is located below the movable clamping plate 333. The movable clamping plate 333 is generally "hook-shaped", forming a "clamp" between the movable clamping plate 333 and the fixed clamping plate 334. The driving component 331 is used to control the opening and closing of the movable clamping plate 333 and the fixed clamping plate 334 to clamp or release the PCB board.

[0043] Preferably, such as Figure 9 , Figure 11As shown, a height adjustment knob 13 is provided between the corresponding feeding notches 21 on both sides of the feeding platform 2. A support base 14 is fixedly connected below the height adjustment knob 13. The support base 14 is screwed to the frame 1. The tilting arm 321 is provided with a through hole 3211 corresponding to the height adjustment knob 13. The tilting arm 321 is made of square steel tube and has excellent bending and torsion resistance. When the tilting arm 321 tilts and falls on the feeding platform 2, the height adjustment knob 13 will pass through the through hole 3211 and abut against the inner wall of the tilting arm 321, providing support for the tilting arm 321. At the same time, the height of the tilting arm 321 on the feeding platform 2 can be adjusted by adjusting the height adjustment knob 13.

[0044] like Figure 12-13 As shown, in this embodiment, a proximity switch 15 and a photoelectric sensor 34 are also provided on the frame 1 next to the rotating plate 34. Two sensing plates 341 are connected to the side of the rotating plate 34 away from the flipping drive 31, extending outward through the bearing seat plate 35. The two sensing plates 341 are vertically arranged. When the flipping frame 32 is perpendicular to the loading platform 2, the two sensing plates 341 correspond to and sense the proximity switch 15 and the photoelectric sensor 341 respectively. When the flipping frame 32 flips and is parallel to the loading platform 2, the signal between the photoelectric sensor 341 and the sensing plate 341 will be disconnected, so that the user can understand the status of the flipping frame 32 in time and send a drive command to the flipping drive 31 to avoid operational errors.

[0045] In this embodiment, a lifting assembly 7 is also provided between the rotating plate 34 and the flipping frame 32. The lifting assembly 7 includes a driving component 71 and several guide rods 72. The driving component 71 is fixed below the rotating plate 34. The output shaft of the driving component 71 passes through the rotating plate 34 and is fixedly connected to the connecting seat 322 of the flipping frame 32. It is used to drive the flipping frame 32 to move upward as a whole, so as to facilitate the precise clamping of the next mechanism. Each guide rod 72 is fixed on the rotating plate 34, and the connecting seat 322 of the flipping frame 32 is sleeved on the guide rod 72, so that the flipping frame 32 is more stable and balanced when sliding up and down along the guide rod 72.

[0046] Preferably, such as Figure 14 As shown, to prevent the PCB board from shifting during transport on the loading table 2, a correction assembly 8 is also provided inside the loading table 2. The correction assembly 8 includes a left positioning component 81, a right positioning component 82, a second synchronous belt 83, and a sixth driving component 84. The sixth driving component 84 is fixedly connected to the frame 1, and its output shaft is fixedly connected to the second synchronous belt 83. The left positioning component 81 and the right positioning component 82 are respectively connected to the two sides of the second synchronous belt 83 that rotate in opposite directions. The left positioning member 81 and the right positioning member 82 have the same structure and are symmetrically arranged. The left positioning member 81 includes a left positioning plate 811, a left upright plate 812, and a left sliding member 813. The left positioning plate 811 is located above the roller 221. One end of the left upright plate 812 passes between two adjacent rollers 221 and is connected to the left positioning plate 811. The other end is connected to the left sliding member 813, so that the left positioning plate 811 slides suspended on the roller 221. Similarly, the right positioning member 82 includes a right positioning plate 821, and the right positioning plate 821 also slides suspended on the roller 221. The extending direction of the left positioning plate 811 and the right positioning plate 821 is the same as the conveying direction of the loading platform. When the PCB board is small, the synchronous belt 83 can be driven to rotate by the drive unit 84, so that the left positioning member 81 and the right positioning member 82 move closer to each other until the distance between the left positioning member 81 and the right positioning member 82 matches the size of the PCB board. This allows the PCB board to be conveyed forward within the space enclosed by the left positioning member 81 and the right positioning member 82, thus limiting the PCB board and ensuring that it is conveyed stably and orderly in the middle of the loading table.

[0047] The following is a detailed explanation of the working principle of this utility model: During loading, the flipping frame 32 first flips 90° and falls into the loading notch 21, and the movable clamping plate 333 and the fixed clamping plate 334 on the flipping frame 32 are in an open state to wait for clamping. Then, according to the size of the PCB board, the baffle 51 in the limiting component 2 5 is moved to the corresponding position to ensure that the position of the PCB board after delivery is directly above the loading notch 21. Then, the PCB board is placed on the roller 221 of the loading table 2, so that the PCB board is transported in the Y-axis direction as the roller 221 rotates. During this process, the synchronous belt 83 can be driven to rotate by the drive unit 84, so that the left positioning plate 811 and the right positioning plate 821 move closer to each other to limit the PCB board and ensure that the PCB board is in the center position and will not shift or rotate. When the photoelectric sensor 11 detects that the PCB board has passed, the lifting drive unit 43 drives the lifting plate 41 to rise to prevent interference from the PCB board behind. When the PCB board abuts against the baffle 51, the pushing assembly 6 is activated, causing the push rod 61 to move along the X-axis under the drive of the driving component 63. When the push rod 61 moves to a certain distance, it will abut against the PCB board and drive the PCB board to move along the X-axis, so that the PCB board falls accurately onto the fixed clamping plate 334. Then, the driving component 331 will drive the movable clamping plate 333 to rotate towards the fixed clamping plate 334, so that the movable clamping plate 333 and the fixed clamping plate 334 complete the action of clamping the PCB board. Finally, the flipping drive component 31 is activated, causing the rotating plate 34 to rotate and drive the flipping frame 32 and the PCB board to flip vertically upward by 90° simultaneously, completing the flipping and loading of the PCB board.

[0048] The innovation of this utility model lies in the sliding connection of a limiting component two above the loading platform. The limiting component two includes a baffle with a groove to avoid the rollers, so that the movement of the baffle and the rollers do not interfere with each other. This not only makes adjustment more convenient but also improves the accuracy of PCB board position adjustment, thereby improving the precise positioning of the flipping component for the PCB board clamping position and achieving fast and stable clamping. In addition, the flipping component is equipped with two clamps, which enhances the balance and stability of PCB board clamping, reduces the risk of PCB board falling during loading, and ensures the stability and reliability of automatic loading.
