Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically, to a dual-station multi-functional feeding machine. Background Technology

[0002] In the electronics manufacturing industry, circuit board production is one of the key steps in ensuring the performance and quality of electronic products. Among these steps, adhesive cutting and pin removal are crucial processes in circuit board manufacturing, playing an irreplaceable role in improving the reliability of electrical connections and the overall structural stability of the circuit board.

[0003] With the rapid development of industrial automation technology, automated PIN stripping and de-pinning devices have emerged to improve production efficiency and reduce costs. These devices integrate advanced robotic arms, precision sensors, and intelligent control systems to achieve efficient and precise processing of circuit boards. However, despite the significant achievements of automation technology in increasing production speed and reducing human intervention, existing PIN stripping and de-pinning devices still face some challenges in the design of their feeding mechanisms.

[0004] Specifically, most current PIN removal and de-pinning devices raise their loading mechanism by the thickness of a circuit board at a time, depending on the process. While this design meets production needs to some extent, its drawbacks are obvious: First, the overall movement of the loading mechanism requires a significant amount of vertical space; second, after each batch of circuit boards is processed, the loading mechanism needs to descend to its original position to replace new boards. During this board replacement period, the production line is idle and cannot continuously perform the PIN removal and de-pinning process, which reduces equipment utilization. Utility Model Content

[0005] In order to overcome the problems of existing feeding mechanisms, such as large space occupation due to vertical movement and inability to operate continuously, this utility model provides a dual-station multi-functional feeding machine.

[0006] The technical solution of this utility model is as follows:

[0007] A dual-station multi-functional feeding machine includes a frame and a feeding mechanism and a conveying mechanism mounted on the frame;

[0008] The feeding mechanism includes two feeding racks and a feeding drive module that matches each feeding rack. The feeding rack can accommodate multiple layers of circuit boards to be processed. The feeding rack is provided with multiple pushing units that correspond one-to-one with each layer of circuit boards to be processed. The feeding drive module includes a first guide rail arranged along a first direction. The feeding drive module moves along the first direction to the position corresponding to the pushing unit and drives the pushing unit to push out the corresponding circuit board to be processed.

[0009] The conveying mechanism is used to accelerate the removal of the circuit board to be processed from the loading rack. The conveying mechanism includes a second guide rail arranged along a first direction and a third guide rail arranged along a second direction. The conveying mechanism moves along the first direction to be on the same horizontal line as the circuit board to be processed being pushed out, so as to accelerate the conveying of the circuit board to be processed. The conveying mechanism moves between the two loading racks along the second direction.

[0010] According to the above-described scheme of this utility model, the pushing unit is located below the corresponding circuit board to be processed, the pushing unit is rotatably connected to the material rack, and the feeding drive module drives the pushing unit to rotate.

[0011] According to the present invention based on the above scheme, the feeding drive module further includes a stepper motor and a drive component. The drive component is mounted on the first guide rail, and the stepper motor is used to control the drive component to move along the first direction on the first guide rail.

[0012] According to the present invention based on the above solution, the driving component includes a slider, a motor mounting plate, and a drive motor. The slider is slidably connected to the first guide rail. The motor mounting plate is provided with a strip hole, and a screw passes through the strip hole to connect the motor mounting plate and the slider. The drive motor is mounted on the motor mounting plate.

[0013] According to the present utility model of the above-described scheme, a connecting block is installed at the output end of the drive motor. The cross-section of the connecting block is U-shaped. One end of the pushing unit near the connecting block extends out of the material rack. The end of the pushing unit is I-shaped. The connecting block and the end of the pushing unit cooperate to drive the rotation of the pushing unit and the material feeding drive module to move along the first direction.

[0014] According to the present invention based on the above scheme, the driving component further includes a laser beam sensor, which is located on the side of the connecting block near the pushing unit, and is used to detect the position of the pushing unit.

[0015] According to the present invention based on the above scheme, the conveying mechanism further includes a conveying component, which is mounted on the third guide rail and is used to move the conveying component along the second direction. The third mounting plate of the third guide rail is mounted on the second guide rail and is used to move the conveying component along the first direction.

[0016] According to the present invention with the above-described scheme, the conveying assembly includes a first conveyor belt mounting plate and a second conveyor belt mounting plate. The first conveyor belt mounting plate is mounted on the third guide rail, and the second conveyor belt mounting plate is mounted on both sides of the first conveyor belt mounting plate. One of the second conveyor belt mounting plates has a conveying motor on its inner side wall and a drive wheel on its outer side wall. The output end of the conveying motor is connected to the drive wheel through a transmission rod.

The laser single-shot sensor is used to detect whether the circuit board to be processed has entered the area where the conveyor belt is located.

[0019] According to the above-described solution, the beneficial effects of this utility model are as follows: the dual-station multi-functional feeding machine of this utility model has a feeding rack equipped with a pushing unit corresponding to a multi-layer circuit board to be processed. The feeding drive module moves along the first direction to the corresponding position of the pushing unit and drives the pushing unit to push out the corresponding circuit board to be processed. At the same time, the conveying mechanism moves along the second direction to the front of the feeding rack that needs to be discharged, and moves along the first direction to a position on the same horizontal line as the circuit board to be processed that is being pushed out. When the circuit board to be processed enters the area where the conveying mechanism is located, the circuit board to be processed is accelerated to be moved out of the feeding rack, completing the feeding process.

[0028] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] It should be noted that the terms "comprising" and "having," and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. Terms such as "set up" should be interpreted broadly; for example, it can refer to a fixed connection, a detachable connection, or an integral part; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements or the interaction between two elements, unless otherwise expressly defined. Terms such as "upper," "lower," "left," "right," "front," "rear," and "bottom" indicate orientations or positions based on the orientations or positions shown in the accompanying drawings, and are only for ease of description and should not be construed as limiting the present technical solution.

[0030] It should be noted that most current PIN stripping and de-pinning devices raise their loading mechanism by the thickness of a circuit board at a time, depending on the process. While this design meets production needs to some extent, its drawbacks are obvious: First, the overall movement of the loading mechanism requires a significant amount of vertical space; second, after each batch of circuit boards is processed, the loading mechanism needs to descend to its original position to replace new boards. During this board replacement period, the production line is idle and cannot continuously perform the PIN stripping and de-pinning process, which reduces equipment utilization.

[0031] like Figures 1-6 As shown, this embodiment provides a dual-station multi-functional feeding machine. The feeding rack 21 is equipped with a push unit 212 corresponding to the multi-layer circuit boards 211 to be processed. The feeding drive module 22 moves along the first direction to the corresponding position of the push unit 212 and drives the push unit 212 to push out the corresponding circuit board. At the same time, the conveying mechanism 30 moves along the second direction to the front of the feeding rack 21 that needs to be discharged, and moves along the first direction to a position on the same horizontal line as the circuit board 211 to be discharged. When the circuit board 211 to be processed enters the area of ​​the conveying mechanism 30, the conveying mechanism accelerates the conveying of the circuit board 211 to be processed and removes it from the feeding rack 21, completing the feeding process. The two feeding racks 21 can work alternately to ensure the continuous operation of the production process, which can significantly improve production efficiency and reduce labor costs.

[0032] Specifically, it includes a frame 10 and a feeding mechanism 20 and a conveying mechanism 30 disposed on the frame 10;

[0033] The feeding mechanism 20 includes two feeding racks 21 and a feeding drive module 22 matched with each feeding rack 21. The feeding rack 21 can accommodate multiple layers of circuit boards 211 to be processed. The feeding rack 21 is provided with multiple pushing units 212 corresponding to each layer of circuit boards 211 to be processed. The feeding drive module 22 includes a first guide rail 221 arranged along a first direction. The feeding drive module 22 moves along the first direction to the corresponding position of the pushing unit 212 and drives the pushing unit 212 to push out the corresponding circuit board 211 to be processed.

[0034] The conveying mechanism 30 is used to accelerate the removal of the circuit board 211 to be processed from the loading rack 21. The conveying mechanism 30 includes a second guide rail 31 arranged along a first direction and a third guide rail 32 arranged along a second direction. The conveying mechanism 30 moves along the first direction to be on the same horizontal line as the circuit board 211 to be pushed out, so as to accelerate the conveying of the circuit board 211 to be processed. The conveying mechanism 30 moves between the two loading racks 21 along the second direction.

[0035] The feeding drive module 22 moves along the first guide rail 221 to the corresponding push unit 212 position and drives the push unit 212 to push out the circuit board 211 to be processed. At the same time, the conveying mechanism 30 moves along the second guide rail 31 to the front of the feeding rack 21 that needs to be unloaded, and moves along the first direction to a position at the same horizontal line as the circuit board being pushed out. When the circuit board 211 to be processed enters the area where the conveying mechanism 30 is located, the conveying mechanism 30 activates the acceleration function to quickly move the circuit board out of the feeding rack 21, completing the feeding process.

[0036] The first direction is the Z-axis direction.

[0037] like Figures 4-6 As shown, in one embodiment, the pushing unit 212 is located below the corresponding circuit board 211 to be processed. The pushing unit 212 is rotatably connected to the material rack, and the feeding drive module drives the pushing unit 212 to rotate. When the pushing unit 212 receives the drive from the feeding drive module 22, it can rotate smoothly and accurately to push and feed the circuit board 211 to be processed.

[0038] The feeding drive module 22 also includes a stepper motor 222 and a drive assembly 223. The drive assembly 223 is mounted on the first guide rail 221, and the stepper motor 222 is used to control the drive assembly 223 to move along the first direction on the first guide rail 221.

[0039] The drive assembly 223 includes a slider 2231, a motor mounting plate 2232, and a drive motor 2233. The slider 2231 is slidably connected to the first guide rail 221. The motor mounting plate 2232 has a slotted hole 2234. Screws pass through the slotted hole 2234 to connect the motor mounting plate 2232 and the slider 2231. The drive motor 2233 is mounted on the motor mounting plate 2232. The slotted hole 2234 allows for fine-tuning of the position of the motor mounting plate 2232, thereby adjusting the position of the output end of the drive motor 2233. This ensures that the output end of the drive motor 2233 is precisely aligned with the push unit 212, achieving stable and efficient power transmission.

[0040] A connecting block 2235 is installed at the output end of the drive motor 2233. The cross-section of the connecting block 2235 is U-shaped. One end of the pushing unit 212 near the connecting block 2235 extends out of the material rack. The end of the pushing unit 212 is straight. The connecting block 2235 cooperates with the end of the pushing unit 212 to drive the rotation of the pushing unit 212 and the movement of the loading drive module 22 along the first direction. Specifically, the straight line where the connecting block 2235 is located intersects the straight line where the straight end of the pushing unit is located, ensuring that when the drive motor 2233 rotates, it can smoothly and effectively drive the pushing unit 212 to rotate, thereby realizing the pushing of the circuit board; at the same time, it can ensure that the loading drive module 22 is not blocked by the pushing unit 212 when moving along the first direction.

[0041] The drive assembly 223 also includes a laser beam sensor 2236, which is located on the side of the connecting block 2235 near the pushing unit 212. The laser beam sensor 2236 is used to detect the position of the pushing unit 212. The laser beam sensor 2236 ensures accuracy and stability throughout the feeding process. Once the pushing unit 212 deviates from the predetermined position, the sensor can immediately send a signal to trigger the corresponding adjustment mechanism, thereby maintaining the smooth progress of the entire feeding process.

[0042] like Figure 3 As shown, in one embodiment, the conveying mechanism 30 further includes a conveying component 33, which is mounted on a third guide rail 32 for moving the conveying component 33 along a second direction. A third mounting plate of the third guide rail 32 is mounted on a second guide rail 31 for moving the conveying component 33 along a first direction.

[0043] The second direction is the X-axis direction.

[0044] The conveying assembly 33 includes a first conveyor belt mounting plate 331 and a second conveyor belt mounting plate 332. The first conveyor belt mounting plate 331 is mounted on the third guide rail 32, and the second conveyor belt mounting plate 332 is mounted on both sides of the first conveyor belt mounting plate 331. One of the second conveyor belt mounting plates 332 has a conveyor motor 333 on its inner side wall and a drive wheel 334 on its outer side wall. The output end of the conveyor motor 333 is connected to the drive wheel 334 through a transmission rod 336. The other second conveyor belt mounting plate 332 has a driven wheel 335. The drive wheel 334 is connected to the driven wheel 335 through a conveyor belt 337, and the conveyor belt 337 can operate smoothly and continuously.

[0045] A pressure roller 338 is installed on the side of the conveyor belt 337 near the feeding mechanism 20, and the pressure roller 338 is located above the conveyor belt 337. The circuit board 211 to be processed is clamped between the pressure roller 338 and the conveyor belt 337, which can accelerate the movement of the circuit board 211 to be processed. The setting of the pressure roller 338 not only improves the conveying efficiency, but also helps to maintain the stability of the circuit board 211 to be processed during the conveying process.

[0046] A laser single-shot sensor 339 is also installed on the side of the conveyor belt 337 near the feeding mechanism 20. The laser single-shot sensor 339 is used to detect whether the circuit board 211 to be processed has entered the area of ​​the conveyor belt 337. When the laser single-shot sensor 339 detects that the circuit board 211 to be processed has entered the area of ​​the conveyor belt 337, it transmits a signal to the conveyor motor 333, and the conveyor motor 333 starts to accelerate, thereby driving the circuit board 211 to be processed to move quickly. When no circuit board 211 to be processed has entered the area of ​​the conveyor belt 337, the output motor is in a stopped or slow-rotating state to reduce energy consumption. A laser single-shot sensor 339 is also installed on the side of the conveyor belt 337 away from the feeding mechanism 20. This sensor is used to detect whether the circuit board 211 to be processed has moved to the end of the conveyor belt 337. When the circuit board 211 to be processed moves to the end of the conveyor belt 337, it transmits a signal to the conveyor motor 333, and the conveyor motor 333 stops rotating. When the circuit board 211 to be processed enters the next process, the conveyor motor 333 continues to stop rotating or resumes slow rotation.

[0047] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0048] The present utility model patent has been described above with reference to the accompanying drawings.
