Technical Field
[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to a circuit board transfer device. Background Technology
[0002] The product upgrade cycle for electronic products has been shortened to a month. New forms and multifunctional electronic products, such as smart wearable devices and high-performance servers, are constantly emerging. This trend has directly driven unprecedented capacity pressure on circuit board production lines, making the need to improve production efficiency urgent. As the starting point of the circuit board production process, the degree of automation and operational efficiency of the loading and unloading processes directly affect the capacity and stability of the entire production line.
[0003] Currently, most circuit board production lines still rely on the traditional manual loading and unloading model. In this model, workers need to frequently move circuit boards from the storage area to the designated location on the production line. The operation is not only time-consuming and labor-intensive, but also poses significant safety hazards. Due to the sharp edges of the circuit boards, and the presence of sharp components on some circuit board surfaces, workers are very likely to suffer cuts during handling, seriously threatening their personal safety. At the same time, long hours of repetitive physical labor can cause both physical and psychological fatigue in workers, leading to an increase in operational error rates and a decrease in production efficiency, making it difficult to meet the urgent demand for circuit board production capacity in the rapid iteration of electronic products.

[0005] The loading and unloading device includes a frame, with a loading component and a unloading component installed on both sides of the frame. A picking component is installed on the same axis as the loading component. Each of the loading, unloading, and picking components includes a transverse pushing part. A rotary cylinder is installed on the pushing end of the transverse pushing part in the unloading component. Suction plate components are installed on both the pushing end of the transverse pushing part and the rotating end of the rotary cylinder in the loading component.

[0006] Furthermore, the transverse pushing part in the loading and unloading assembly includes a rack fixed on the same side of the two side plates of the frame, and a slide rod fixed on the side opposite to the rack. A movable plate that slides with the frame is passed through the slide rod. A gear drive motor that meshes with the rack is installed on the top of the movable plate. A lower pushing cylinder is also installed. The ejector ends of the two lower pushing cylinders are respectively fixed with a long plate that slides on the movable plate and a lower top plate. The rotary cylinder is installed on the lower top plate, and a set of suction plate assemblies is fixed to the long plate.
[0007] Furthermore, the length of the rack located in the feeding assembly on the frame is shorter than that of the rack in the unloading assembly.
[0008] Furthermore, the transverse pushing part in the material handling assembly includes a pushing cylinder fixed inside the frame body, and a pushing plate that is slidably connected to the inner side, which passes through the slide rod in the feeding assembly and is fixed to the piston rod of the pushing cylinder. A lower pushing cylinder is also installed on the pushing plate, and a long plate is fixed to the ejector end of the lower pushing cylinder. The long plate slides with the pushing plate. The second adsorption device is installed at the bottom of the long plate, and a baffle is fixed on the slide rod.
[0009] Furthermore, the suction plate assembly includes a support plate, four sets of sliding plates are slidably connected to one side of the support plate, and an adjusting part for driving the four sets of sliding plates to move is also installed on the same side, as well as two sets of side stops for interchanging partial limiting. A first suction device is installed on the sliding plate.
[0010] Furthermore, the adjusting part includes a side-push cylinder mounted on one of the slide plates. The piston rod of the side-push cylinder is fixed with a side-push block. The side-push block is fixed to another slide plate. Each of the four slide plates has a follower block. A guide rod passes through between the follower blocks. Two sleeve blocks are sleeved on the outside of the guide rod, and a spring is sleeved between two of the follower blocks. The two sleeve blocks are respectively located between two pairs of follower blocks.
[0011] Furthermore, four sets of L-shaped blocks are fixed on one side of the bearing plate, and the top of the slide plate forms a protruding end opposite to the convex edge of the L-shaped block.
[0012] Furthermore, the conveying device includes a conveying platform, with two pairs of base plates installed at the bottom of the conveying platform. Push cylinders with opposite ejection ends are installed on the base plates. The piston rod of the push cylinder is fixed with a stop that can extend to the top of the conveying platform. Two sets of tail stops are fixed at the tail end of the conveying platform.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0014] The circuit board transfer device, through the coordinated operation of the loading, unloading, and picking components of the loading and unloading device, realizes the automated transfer of circuit boards from the conveyor to the pre-placement table, to the workstation turntable, and from the workstation turntable back to the conveyor. This completely eliminates the inefficient manual handling mode, significantly improves the production line's capacity efficiency, and avoids direct contact between manuals and the sharp edges and components of the circuit boards, fundamentally eliminating the risk of cuts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0023] Please see Figure 1-6This embodiment of a circuit board transfer device includes an operating platform 1, on which, from right to left, are mounted a workstation rotary table 2, a pre-placement table 5, a conveying device 3, and a loading / unloading device 4 spanning above the workstation rotary table 2, the pre-placement table 5, and the conveying device 3. The loading / unloading device 4 includes a frame 41, on which a loading assembly and a picking assembly are mounted on a long frame plate on the back, and a unloading assembly is mounted on a long frame plate on the front. The conveying device 3 includes a conveying platform 31, the bottom of which is fixed by two pairs of base plates 32. Pushing cylinders 33, arranged opposite each other, are mounted on the base plates 32, and the piston rods of the pushing cylinders 33 are fixed. There are stops 34 extending to the top of the conveyor 31. The first stop blocks prevent the collection tray from waiting, while the middle stop blocks the collection tray to be in a designated position for easy loading. The two sets of tail stops 35 at the tail end of the conveyor 31 limit the collection tray, so that the collection tray waits for collection at the tail end. The loading component is used to remove the circuit board from the collection tray on the conveyor and then transfer it to the pre-placement table. The unloading component then transfers it to the rotating table at the work station for processing. After processing, the unloading component removes it and puts it back into the collection tray for collection, thereby improving automation, reducing manual intervention and improving safety.
[0024] in, Figure 4 ,by Figure 1 In the indicated direction, the feeding assembly includes a rack 42 fixed to the back side of a long frame plate on the back of the frame 41, a slide rod 49 fixed to the front side of the long frame plate on the back, a movable plate 43 that slides with the long frame plate sleeved on the slide rod 49, a gear drive motor 44 and a lowering cylinder 45 mounted on the movable plate 43, the gear end of the gear drive motor 44 meshing with the rack 42, and a long plate 413 that slides with the movable plate 43 fixed to the piston rod of the lowering cylinder 45, and a suction plate assembly 48 mounted on the bottom of the long plate 413.
[0025] The meshing transmission between the gear-driven motor and the rack and pinion forms a rigid transmission structure. Compared with belt or chain transmission, this reduces slippage and ensures the displacement accuracy of the lateral movement of the moving plate. It avoids positional misalignment between the suction plate assembly and the circuit board due to transmission errors, improving the accuracy of loading and positioning. This controls the transfer of the circuit board from the conveyor to the pre-placement table. The sliding rod and the moving plate work together to effectively limit the swing of the moving plate, maintaining the stability of the suction plate assembly and preventing the circuit board from falling off due to shaking during suction. The piston rod of the lower cylinder drives the long plate to slide along the moving plate, realizing the vertical lifting and lowering of the suction plate assembly. This structure can precisely control the distance between the suction plate assembly and the circuit board, ensuring both negative pressure sealing during suction and preventing excessive downward pressure from damaging the components on the surface of the circuit board.
[0026] In addition, the material handling assembly includes a push plate 412 that is slidably connected to the front of the back long frame plate and passes through the corresponding slide rod 49, and a push cylinder 411 that is also installed on the front of the back long frame plate. The piston rod of the push cylinder 411 is fixed to the push plate 412. A lower push cylinder 45 is installed on the push plate 412. The piston rod of the lower push cylinder 45 is fixed to a long plate 413 that slides with the push plate 412. A second adsorption device 414 is installed at the bottom of the long plate 413. A baffle 410 is fixed on the outer side of the slide rod 49 between the feeding assembly and the material handling assembly.
[0027] The push cylinder drives the push plate to slide linearly along the slide bar, enabling the material handling component to move a wide range in one direction. The material handling position can be flexibly adjusted, allowing the second adsorption device to move between the pre-placement platform and the stationary rotating platform. The lower push cylinder drives the long plate to slide relative to the push plate, increasing the vertical movement dimension and adapting to material handling requirements at different heights. The slide bar acts as a guide rail, providing a stable sliding path for the push plate and ensuring the straightness and accuracy of the material handling process. The baffle plate can be used as a limit or positioning reference to ensure that the material handling component stops accurately at a specific position, improving material handling accuracy.
[0028] At the same time, such as Figure 3 ,by Figure 1 In the indicated direction, the unloading assembly includes a rack 42 fixed to the back of the front long frame plate of the frame 41. The rack 42 is longer than the rack 42 on the back. A slide rod 49 is also fixed to the front of the front long frame plate. A movable plate 43 that slides with the front long frame plate passes through the slide rod 49. A gear drive motor 44 that meshes with the rack 42 is installed on the top of the movable plate 43. A lower top cylinder 45 is also installed on the top. The piston rod of the lower top cylinder 45 is fixed to a lower top plate 46 that slides with the movable plate 43. A rotary cylinder 47 is installed on the lower top plate 46. A suction plate assembly 48 is installed on the rotating shaft end of the rotary cylinder 47.
[0029] The gear-driven motor and rack mechanism enable the moving plate to move stably in a straight line along the slide bar, achieving a wide range of horizontal position adjustments. The lower top cylinder drives the lower top plate to slide up and down, providing vertical movement to facilitate approaching or moving away from the material placement position. The rotary cylinder drives the suction plate assembly to rotate, enabling material angle adjustment to adapt to different feeding directions or posture requirements. The slide bar, acting as a guide rail, restricts the movement trajectory of the moving plate, reducing offset and swaying during movement and improving stability.
[0030] like Figure 5-6 ,by Figure 5As shown, the suction plate assembly 48 includes a support plate 481 fixed to the rotating end of the rotary cylinder 47 and the bottom of the long plate 413 in the unloading assembly. Four sets of L-shaped blocks 482 are fixed to the front of the support plate 481. From left to right, the protruding ends of the first and third L-shaped blocks 482 face the same side, and the protruding ends of the second and fourth L-shaped blocks 482 also face the same side. Four sets of sliding plates 483 are slidably connected to the front of the support plate 481. The top of each of the four sliding plates 483 has a protruding edge extending to the opposite side of the corresponding L-shaped block 482. A first suction device 484 is installed at the bottom of the sliding plate 483. A side-push cylinder 485 is hinged to the fourth sliding plate 483. The piston rod of cylinder 485 is fixed with a side push block, which is fixed to the first slide plate 483. Two side stops 490 are fixed on the front of the bearing plate 481. The left side stop 490 is opposite to the side push block, and the right side stop 490 is opposite to the fourth slide plate 483. Each of the four slide plates 483 has a follower block 486 fixed on its front, which faces the same direction as the protruding end of the corresponding L-shaped block. A guide rod 487 is passed through the four follower blocks 486. Both ends of the guide rod 487 are provided with end blocks, and a sleeve block 488 located between the two follower blocks 486 on the left and the two follower blocks 486 on the right is also sleeved on the outside. A spring 489 located between the two follower blocks 486 in the middle is also sleeved on the outside.
[0031] In the reduced spacing state: when the piston rod of the side-push cylinder is in the retracted state, the side-push block separates from the left side stop. At this time, the protruding ends of the first and fourth sliding plates abut against the protruding ends of the corresponding first and fourth L-shaped blocks to their limit positions. During the movement of the sliding plates, the first and fourth follower blocks move synchronously, pushing the two follower blocks in the middle through the sleeve block, thereby compressing the spring located between the two follower blocks in the middle, ultimately shortening the distance between the four sets of first adsorption devices.
[0032] Increased Spacing State: When the piston rod of the side-push cylinder extends, the side-push block pushes the first slide plate to the left until it contacts the left side rail. At the same time, under the linkage of the mechanical structure, the fourth slide plate also moves to contact the right side rail. During the movement of the first and fourth slide plates, they synchronously drive the corresponding follower blocks to move. When the first and fourth follower blocks move in opposite directions, the spring in the compressed state releases its elastic force, pushing the two follower blocks in the middle to move, thereby driving the two sets of slide plates to move synchronously. During this process, the two L-shaped blocks 482 in the middle play a limiting role for the two middle slide plates, ensuring the stability and accuracy of the slide plate movement, and finally realizing the increase of the spacing between the four sets of slide plates. Through the extension and retraction control of the piston rod of the side-push cylinder, the suction plate assembly can flexibly adjust the spacing between the four sets of slide plates to adapt to the width requirements of different positions.
[0033] The working principle of the above embodiments is as follows:
[0034] The conveyor table transports the collection tray. The piston rod of the push cylinder drives the stop blocks at the top of the conveyor table. The first stop block keeps the collection tray in a pre-positioned wait at the beginning of the conveyor table, while the middle stop block precisely controls the collection tray to stop at a designated position, facilitating loading and unloading. Two sets of tail stops limit the collection tray, keeping it in place for collection at the tail end. In the loading assembly, the rack on the back side of the long frame plate on the back of the frame meshes with the gear drive motor on the moving plate, forming a rigid transmission structure. Compared to belt or chain drives, this structure effectively avoids slippage, ensuring high precision in the lateral displacement of the moving plate and ensuring precise alignment between the suction plate assembly and the circuit board. The sliding rod cooperates with the moving plate to limit the swing of the moving plate and maintain... The suction plate assembly stabilizes the circuit board, preventing it from falling off during adsorption. A lower cylinder drives the long plate, causing the bottom suction plate assembly to rise and fall vertically, precisely controlling the distance between the suction plate assembly and the circuit board while avoiding damage to the components. Furthermore, the suction plate assembly uses a side-push cylinder piston rod to extend and retract, flexibly adjusting the spacing of the four sets of sliding plates to accommodate circuit boards of different widths. This allows for the accurate removal of circuit boards from the collection tray on the conveyor and their transfer to the pre-placement stage. The material-picking assembly's push-top cylinder drives the push plate to slide linearly along the slide bar, enabling a wide range of horizontal movement and flexible adjustment of the picking position. A lower cylinder drives the long plate to slide relative to the push plate, increasing the vertical movement dimension and meeting the requirements for picking up circuit boards at different heights. To meet material requirements, a sliding rod acts as a stable guide rail, ensuring the straightness and accuracy of the material handling process. A stop plate serves as a limit reference, ensuring the material handling component stops accurately at a specific position, thus precisely moving the circuit board from the pre-placement table to the rotary table for processing. The rack and pinion on the long frame plate on the front of the unloading component works in conjunction with a gear-driven motor to ensure stable linear movement of the moving plate, allowing for a wide range of horizontal position adjustments. A lower top cylinder drives the lower top plate to move vertically, facilitating approaching or moving away from the material placement location. A rotary cylinder drives the suction plate assembly to rotate, adjusting the material angle to meet different unloading directions and posture requirements. Similarly, the suction plate assembly uses a side-push cylinder to adjust the slide plate spacing, moving the processed circuit board from the workstation. When the rotating platform is removed and the collection tray is returned, the piston rod of the side-push cylinder of the suction plate assembly retracts, causing the side-push block to separate from the left side rail. The protruding ends of the first and fourth sliding plates abut against the protruding ends of their corresponding L-shaped blocks to their limit positions. The first and fourth follower blocks move synchronously, and the central spring is compressed by the sleeve block, reducing the distance between the four sets of first suction devices. When the piston rod of the side-push cylinder extends, the side-push block pushes the first sliding plate to the left until it contacts the left side rail. At the same time, the fourth sliding plate also moves to contact the right side rail. The first and fourth follower blocks move in opposite directions, and the compressed spring releases its elasticity, pushing the central follower block to move the corresponding sliding plate, thus increasing the distance between the four sets of sliding plates. During the movement of the sliding plates, the L-shaped block and the side rail act as limiters, ensuring stable and accurate movement of the sliding plates. This allows the suction plate assembly to flexibly adjust the spacing to adapt to the suction and handling needs of circuit boards of different widths.
[0035] The entire set of equipment achieves a fully automated process for circuit boards, from loading onto the collection tray, processing to unloading and collection, through the precise coordination of its various components. This significantly reduces manual intervention and improves production safety and efficiency.
