Description

Technical Field

[0001] This utility model relates to the field of prepreg cutting and processing technology, and in particular to a dual-drag prepreg cutting and stacking device. Background Technology

[0002] Prepreg is a key basic material for manufacturing multilayer printed circuit boards, and it is usually shipped in roll form. Before subsequent lamination processing, it needs to be cut into individual pieces according to fixed dimensions and stacked neatly to facilitate use, transportation and save storage space.

[0003] Currently, most prepreg cutting and stacking equipment used in the industry is based on a single-motor drive structure, completing feeding, cutting, and stacking processes sequentially through mechanical linkage. Because all actions share the same power source, there is a strong coupling relationship between the processes, resulting in insufficient system flexibility. Specifically, the feeding length is unstable, making it difficult to guarantee consistent cutting dimensions; the stacking process is easily affected by fluctuations in preceding processes, leading to decreased alignment accuracy between layers. Furthermore, each process cannot independently adjust its operating rhythm, requiring long waiting times between actions, resulting in a slow overall equipment cycle time and difficulty meeting the demands of high-efficiency production. More seriously, even a small error in any link of the mechanical linkage will be transmitted and accumulated in subsequent actions, not only reducing the quality of the finished product but also frequently causing downtime for debugging, significantly weakening the equipment's continuous operation capability, and increasing the frequency of manual intervention and maintenance costs.

[0004] Therefore, it is necessary to design a dual-drag semi-cured sheet cutting and stacking device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of current prepreg cutting and stacking equipment, which mostly adopt single-motor mechanical linkage, strong process coupling leading to unstable feeding, inaccurate cutting, stacking deviation, unadjustable rhythm, slow cycle time, easy accumulation of errors, frequent shutdowns, poor continuous operation, and high maintenance costs, this utility model provides a dual-drive prepreg cutting and stacking device.

[0006] The technical implementation scheme of this utility model is as follows: a dual-drag type prepreg cutting and stacking device, including a support frame, a placement plate, a controller, a top frame, a mounting housing, a first sliding frame, a second sliding frame, screws, motors, and clamping components. The placement plate is fixedly connected to the lower part of the support frame, the controller is fixedly connected to the left part of the support frame, the top frame is fixedly connected to the top of the support frame, the mounting housing is fixedly connected to the middle part of the top frame, the first sliding frame is slidably connected to the top of the mounting housing, the second sliding frame is slidably connected to the inside of the mounting housing, screws are rotatably connected to both sides inside the mounting housing, the first sliding frame is threadedly connected to the upper screw, the second sliding frame is threadedly connected to the lower screw, motors are fixedly connected to the upper left side and the lower right side of the mounting housing, the two motors are electrically connected to the controller, the output shafts of the two motors are inserted into the inside of the mounting housing and fixedly connected to the corresponding screws, and two clamping components are provided on the right side of both the first and second sliding frames.

[0007] Furthermore, both the first and second sliding frames are U-shaped structures and are staggered.

[0008] Furthermore, the clamping assembly includes an electric slide rail, a slider, a cylinder, a lower clamping plate, and an upper clamping plate. The lower right side of both the first and second sliding frames is fixedly connected to an electric slide rail. All four electric slide rails are electrically connected to the controller. A slider is slidably connected to the right side of each electric slide rail. A cylinder is fixedly connected to one side of the right side of each slider. All four cylinders are electrically connected to the controller. A lower clamping plate is fixedly connected to the other side of the right side of each slider. An upper clamping plate is fixedly connected to the bottom of the piston rod of each cylinder. Each upper clamping plate is symmetrically distributed with the corresponding lower clamping plate.

[0009] Furthermore, it also includes side plates, with the right side of the support frame fixedly connected to the side plates.

[0010] Furthermore, it also includes a warning light, which is fixedly connected to the top of the controller and electrically connected to the controller.

[0011] Furthermore, it also includes cushioning pads, with cushioning pads fixedly connected to the bottom of each upper clamping plate and the top of each lower clamping plate, and each cushioning pad is made of soft material.

[0012] The present invention has the following advantages: 1. The present invention adopts two completely independent drive and execution systems, namely the first sliding frame and the second sliding frame, and is coordinated by the controller, which fundamentally changes the strong coupling working mode of traditional single motor mechanical linkage. This dual-drive architecture enables the feeding and stacking processes to be decoupled in space and time.

[0013] 2. This utility model uses two independent sliding frame systems. When a single sliding frame or its drive system fails, it usually does not cause the other system to fail immediately. The controller can alarm through warning lights and stop the machine in an orderly manner, avoiding the chain reaction of partial jamming causing the entire line to be paralyzed in traditional linkage mechanisms.

Detailed Implementation

[0019] Example: A dual-drag type prepreg cutting and stacking device, such as Figures 1-4As shown, the system includes a support frame 1, a placement plate 2, a controller 3, a top frame 5, a mounting housing 7, a first sliding frame 8, a second sliding frame 9, a screw 10, a motor 11, an electric slide rail 12, a slider 13, a cylinder 14, a lower clamping plate 15, an upper clamping plate 16, a side plate 6, a warning light 4, and a buffer pad 17. The placement plate 2 is welded to the lower right side of the support frame 1. The controller 3 is mounted on the upper left side of the support frame 1 via screws. The top frame 5 is welded to the top side of the support frame 1, and the mounting housing 7 is welded to the middle side of the top frame 5. A first sliding bracket 8 is slidably connected to the top left side of the mounting housing 7, and a second sliding bracket 9 is slidably connected to the inside right side of the mounting housing 7. Both the first sliding bracket 8 and the second sliding bracket 9 are U-shaped structures and are staggered. Screws 10 are rotatably connected to both the upper and lower sides of the inside of the mounting housing 7. The first sliding bracket 8 is threadedly connected to the upper screw 10, and the second sliding bracket 9 is threadedly connected to the lower screw 10. Motors 11 are mounted on the upper left side and the lower right side of the mounting housing 7 using screws. Two motors 11 are electrically connected to the controller 3. The output shafts of both motors 11 are inserted into the mounting housing 7 and fixedly connected to the corresponding screws 10. The lower right side of the first sliding frame 8 and the second sliding frame 9 are both equipped with electric slide rails 12 by screws. All four electric slide rails 12 are electrically connected to the controller 3. Each electric slide rail 12 has a slider 13 slidably connected to its right side. Each slider 13 has a cylinder 14 installed on its upper right side by screws. All four cylinders 14 are electrically connected to the controller 3. Each slider 13 has a lower clamping plate 15 installed on its lower right side by screws. Each cylinder 14 has an upper clamping plate 16 installed on its piston rod bottom side by screws. Each upper clamping plate 16 is symmetrically distributed with its corresponding lower clamping plate 15. The right side of the support frame 1 is fixedly connected to the side plate 6. The top side of the controller 3 is equipped with a warning light 4 by screws. The warning light 4 is electrically connected to the controller 3. Each upper clamping plate 16 and each lower clamping plate 15 is fixedly connected to a buffer pad 17. Each buffer pad 17 is made of soft material.

[0020] After the device is powered on, the controller 3 initializes the system. In the initial state, the first sliding frame 8 is located on the left side above the mounting housing 7, and its clamping components are in the open state; the second sliding frame 9 is located on the right side inside the mounting housing 7, and its clamping components are also in the open state. Both motors 11 are in the stopped state. The pre-cut semi-cured sheets are continuously supplied by the upstream equipment to the feeding position on the right side of the device, waiting to be clamped.

[0021] Controller 3 first starts the working cycle of the first sliding frame 8. The two clamping components on the first sliding frame 8 are activated. The electric slide rail 12 drives the slider 13 to move downwards for fine adjustment to align with the feeding position. Then, the piston rod of the cylinder 14 extends downwards, pushing the upper clamping plate 16 down and working in conjunction with the lower clamping plate 15 to firmly clamp a single semi-cured sheet located at the feeding position. The buffer pad 17 protects the material surface. After clamping, the motor 11 in the upper left of the mounting housing 7 starts, driving the screw 10 above to rotate clockwise. The first sliding frame 8 is driven to move horizontally to the left along the guide rail at the top of the mounting housing 7. The clamped single sheet is steadily transported from the right feed position to the left placement plate 2. When the first sliding frame 8 moves to the predetermined stacking position above the placement plate 2, the motor 11 stops. Then, the piston rod of the cylinder 14 retracts upward, driving the upper clamping plate 16 to lift, thereby releasing the clamped semi-cured sheet and allowing it to fall smoothly and neatly onto the placement plate 2. After the unloading is completed, the motor 11 reverses, driving the first sliding frame 8 to move horizontally to the right and return to its initial position on the left side of the mounting housing 7, ready for the next unloading. At the same time, the electric slide rail 12 of its clamping component can drive the slider 13 to reset and adjust to the optimal unloading posture. When the first sliding frame 8 begins its leftward transport stroke or during its return journey, the controller 3 instructs the second sliding frame 9 to start its work cycle to achieve alternating operation. The two clamping components on the second sliding frame 9 first perform the clamping action. Its electric slide rail 12 cooperates with the cylinder 14 to clamp another semi-cured sheet that has reached the feeding position. Then, the motor 11 fixedly connected to the lower right of the mounting housing 7 starts, driving the screw 10 below to rotate counterclockwise, driving the second sliding frame 9 to move horizontally to the right along the guide rail inside the mounting housing 7. This direction of movement is opposite to that of the first sliding frame 8, which is intended to transport the clamped sheet and place it on another preset stacking point on the placement plate 2. It usually intersects with the feeding point of the first sliding frame 8 to achieve more stable stacking. When the second sliding frame 9 moves to its target feeding position, the motor 11 stops, the cylinder 14 releases, and the sheet is released. After feeding is completed, the motor 11 reverses, driving the second sliding frame 9 to move horizontally to the left, returning to its initial position on the right side of the mounting housing 7, ready for the next feeding.

[0022] Through precise timing control by controller 3, the movement cycles of the first sliding frame 8 and the second sliding frame 9 are set to be staggered. When the first sliding frame 8 performs material picking, leftward movement, and material placement, the second sliding frame 9 may be in a return or waiting state. When the first sliding frame 8 starts to return, the second sliding frame 9 immediately starts its rightward movement and material picking process. This cycle repeats, and the two sliding frames, like a relay, take out the cut pieces from the right-side feeding position in turn, and place them on the left-side placement plate 2 in an alternating manner through leftward and rightward movement paths. During the entire operation, controller 3 monitors the status of each execution element in real time. If situations such as feeding interruption, stacking abnormality, or element failure occur, controller 3 can immediately stop the equipment operation and trigger the warning light 4 fixed on its top side to issue an alarm signal to prompt the operator to handle the situation. The side plate 6 provides additional lateral support for the support frame 1, ensuring the overall rigidity and accuracy of the device in long-term reciprocating motion.
