Abstract
Description
Technical Field
[0001] This utility model relates to a conveying device, and more particularly to a segmented conveying device for an integrated PCB drilling and edge-wrapping production line. Background Technology
[0002] In PCB (Printed Circuit Board) manufacturing, drilling and edge banding are two critical processes, and their processing accuracy directly affects the electrical performance and reliability of the PCB board. Traditional PCB production lines typically employ a segmented processing model, separating the drilling and edge banding processes and transferring them manually or via independent conveyor equipment. This production method is not only inefficient, but repeated handling can also lead to positioning deviations in the PCB board, affecting processing accuracy.
[0003] In existing technologies, some integrated equipment attempts to integrate drilling and edge banding functions. However, in existing technologies, PCB boards are prone to displacement due to vibration or external forces during processing, resulting in drilling position deviation or uneven edge banding, which leads to a decrease in processing accuracy. Secondly, traditional burr cleaning requires additional workstations or manual intervention, increasing production cycle time and labor costs.
[0004] Therefore, it is necessary to design a conveyor device for an integrated PCB drilling and edge-wrapping production line that can achieve high-precision clamping and automatic burr removal, so as to improve processing efficiency and product quality. Utility Model Content
[0005] The technical solution is: a segmented conveying device for an integrated PCB drilling and edge-wrapping production line, including a frame. A drilling machine, an edge-wrapping machine, and an installation frame are arranged side by side from front to back on the top of the frame. A conveying component is provided on the frame for sequentially conveying PCB boards to the drilling machine, edge-wrapping machine, and installation frame for corresponding operations. A fixing plate is also installed on the frame, located between the upper and lower conveyor belts in the conveying component. L-shaped plates are symmetrically slidably arranged on both sides of the fixing plate along its length. An electric push rod is provided on the fixing plate, and the movable end of the electric push rod is connected to the L-shaped plate. The extension and retraction movement of the electric push rod drives the L-shaped plates on both sides to move closer or further apart.
[0006] Furthermore, uprights are symmetrically arranged on the top of the fixed plate, and the uprights are located on the outside of the L-shaped plate. A bracket is slidably arranged on the uprights, and the bracket is located above the L-shaped plate. A pressure roller is rotatably connected to the end of the bracket away from the uprights, and the pressure roller is located on the inside of the L-shaped plate. A second elastic element is wound around the uprights, and the two ends of the second elastic element are respectively connected to the bracket and the fixed plate.
[0007] Furthermore, the internal lateral length of the zigzag frame is consistent with the extension and retraction stroke of the electric push rod.
[0008] Furthermore, a guide plate is connected to the end of the L-shaped plate near the loading point of the frame. The guide plate is used to guide and align the material during loading.
[0009] Furthermore, a U-shaped frame is installed on one side of the top of the fixed plate, and a motor is installed on the other side at a position corresponding to the U-shaped frame. A rotating rod is connected to the output shaft of the motor. The end of the rotating rod away from the motor is movably engaged with a sleeve that is slidably set on the U-shaped frame. Limit blocks can be detachably set at both ends of the rotating rod. A burr brush is arranged in an array on the rotating rod. A first elastic element is set on the U-shaped frame. The first elastic element is used to keep the sleeve and the rotating rod effectively engaged.
[0010] Furthermore, an ion water sprayer is installed within the mounting frame, which is used to rinse and clean the PCB board.
[0011] Furthermore, a dryer is installed inside the mounting frame, located on the two longitudinal inner walls of the mounting frame.
[0012] Furthermore, a collection frame is provided on the rack, and the collection frame is located below the conveyor belt in the conveying assembly.
[0013] Furthermore, the conveyor belt of the conveyor assembly is provided with limiting protrusions for limiting the PCB board.
[0014] The beneficial effects are as follows: 1. The symmetrical L-shaped plate is driven to move synchronously by the electric push rod, and the dynamic clamping mechanism composed of the pressure roller and the second elastic element forms a three-point positioning, which effectively suppresses the displacement of the PCB board caused by processing vibration and ensures the accuracy of the drilling position.
[0015] 2. The motor drives the rotating rod to rotate, thereby driving the burr brush to rotate. This allows the burr brush to clean the burrs at the edges of the holes on the PCB board during the PCB board conveying process, without the need for additional workstations or manual intervention, significantly improving production efficiency.
[0016] 3. The combined design of the ion water sprayer and dryer can thoroughly remove debris and residue from the PCB board surface, and ensure surface cleanliness through double-sided drying to avoid contamination in subsequent processes. Attached Figure Description

Detailed Implementation
[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0023] Example: A segmented conveyor system for an integrated PCB drilling and edge-wrapping production line, such as... Figures 1-3 As shown, the system includes a frame 1, a conveyor assembly 2, a punching machine 3, an edge-wrapping machine 4, and a mounting frame 5. The punching machine 3, edge-wrapping machine 4, and mounting frame 5 are arranged side-by-side from front to back on the top of the frame 1. The frame 1 is equipped with a conveyor assembly 2 for sequentially conveying the PCB board 100 to the punching machine 3, edge-wrapping machine 4, and mounting frame 5 for corresponding operations. The conveyor assembly 2 includes conveyor rollers installed at both ends of the frame 1, a conveyor belt wound around the conveyor rollers, and a power device to drive the conveyor rollers to rotate, thereby effectively conveying the PCB board 100. The conveyor belt of the conveyor assembly 2 is equipped with limiting protrusions 21 for limiting the PCB board 100, ensuring the stability of the PCB board 100 during conveying. For qualitative and precise purposes, a fixing plate 6 is also installed on the frame 1. The fixing plate 6 is located between the upper and lower conveyor belts in the conveying assembly 2. L-shaped plates 7 are symmetrically slidably arranged on both sides of the fixing plate 6 along its length. The L-shaped plates 7 are on the same horizontal plane as the upper conveyor belt in the conveying assembly 2. An electric push rod 8 is installed on the fixing plate 6. The movable end of the electric push rod 8 is connected to the L-shaped plate 7. The extension and retraction movement of the electric push rod 8 drives the L-shaped plates 7 on both sides to move closer or further apart. When the electric push rod 8 extends, the L-shaped plates 7 on both sides move towards each other, thereby clamping the PCB board 100 located on the conveyor belt of the conveying assembly 2, so that there is a gap between the bottom of the PCB board 100 and the conveyor belt. At this time, the drill bit of the drilling machine 3 can perform drilling operations on the PCB board 100.
[0024] like Figure 2 and Figure 3As shown, multiple uprights 151 are symmetrically arranged on the top of the fixed plate 6. The uprights 151 are located on the outside of the L-shaped plate 7. A bracket 152 is slidably mounted on the uprights 151. The bracket 152 is located above the L-shaped plate 7. A pressure roller 15 is rotatably connected to the end of the bracket 152 away from the uprights 151. The pressure roller 15 is located inside the L-shaped plate 7. The internal lateral length of the bracket 152 is consistent with the extension stroke of the electric push rod 8. This arrangement ensures that when the L-shaped plate 7 is pushed by the electric push rod 8, the pressure roller 15 maintains a vertical limit on the PCB board 100. Combined with the L-shaped plate 7, it forms a three-point limit effect on the PCB board 100, ensuring its stability during drilling operations. A second elastic element 16 is wound around the uprights 151. The two ends of the second elastic element 16 are connected to the bracket 152 and the fixed plate 6, respectively. The arrangement of the second elastic element 16 ensures that the pressure roller 15 remains in contact with the surface of the PCB board 100.
[0025] like Figure 3 As shown, the end of the L-shaped plate 7 near the loading point of the frame 1 is connected to a guide plate 9, which is used to guide and align the material during loading.
[0026] like Figure 3 As shown, a U-shaped frame 61 is installed on one side of the top of the fixed plate 6, and a motor 10 is installed on the other side at a position corresponding to the U-shaped frame 61. A rotating rod 11 is connected to the output shaft of the motor 10. The end of the rotating rod 11 away from the motor 10 is detachably engaged with a sleeve 12 that is slidably set on the U-shaped frame 61. Limiting blocks 111 are detachably set at both ends of the rotating rod 11. Burr brushes 14 are arranged in an array on the rotating rod 11. The limiting blocks 111 are used to limit the burr brushes 14. The detachable arrangement of the limiting blocks 111 and the rotating rod 11 facilitates the adjustment of the specific position of the limiting blocks 111 on the rotating rod 11 according to the number and position of the burr brushes 14. A first elastic element 13 is provided on the U-shaped frame 61. The first elastic element 13 is used to keep the sleeve 12 and the rotating rod 11 effectively engaged.
[0027] like Figure 1 and Figure 4 As shown, an ion water sprayer 17 is installed inside the mounting frame 5. The ion water sprayer 17 is used to rinse and clean the PCB board 100, thereby removing debris from the surface of the PCB board 100.
[0028] like Figure 4 As shown, a dryer 19 is installed inside the mounting frame 5. The dryer 19 is located on the two longitudinal inner walls of the mounting frame 5. The dryer 19 quickly dries the PCB board 100 from both sides of the mounting frame 5 to ensure the cleanliness of the PCB board 100 surface. The dryer 19 is set as an infrared heating tube.
[0029] like Figure 4As shown, a collection frame 20 is provided on the frame 1. The collection frame 20 is located below the conveyor belt in the conveying assembly 2. The debris generated during the drilling operation of the drilling machine 3 and the wastewater from the sprayer 17 spraying and cleaning the PCB board 100 fall into the collection frame 20 through the gap of the conveyor belt, so as to realize the centralized treatment of waste.
[0030] When in use, when the PCB board 100 enters the conveyor belt from the loading end, the guide plate 9 guides it to accurately enter the processing area. When the PCB reaches above the fixed plate 6, the electric push rod 8 drives the two L-shaped plates 7 to move synchronously towards each other, forming a clamping space. The vertical and horizontal sections of the L-shaped plates 7 work together to clamp the PCB 100 from the conveyor belt of the conveyor assembly 2, limiting the PCB 100 and facilitating drilling by the punching machine 3 or edge banding by the edge banding machine 4. Simultaneously, the U-shaped bracket 152 presses down under the action of the second elastic element 16, causing the pressure roller 15 to press tightly against the surface of the PCB 100, forming a three-point dynamic clamp with the L-shaped plates 7, preventing displacement of the PCB 100 due to processing vibration. Subsequently, the punching machine 3 moves down to perform drilling on the PCB 100. After the punching machine 3 completes drilling, the electric push rod 8 retracts to drive the two L-shaped plates 7 to move synchronously in opposite directions, thereby releasing the clamping of the PCB 100 by the L-shaped plates 7, allowing the side PCB 100 to return to the conveyor belt of the conveyor assembly 2. Component 2 conveys the PCB board 100 to the area below the rotating rod 11. The motor 10 drives the rotating rod 11 to rotate, which in turn drives the burr brush 14 mounted on it to rotate at high speed to clean the burrs at the edges of the holes on the PCB board 100. After the burrs on the PCB board 100 are cleaned, the conveying component 2 conveys the PCB board 100 directly below the edge-wrapping machine 4. Then, the electric push rod 8 drives the two L-shaped plates 7 on both sides to move synchronously towards each other to hold the PCB board 100, thus facilitating edge-wrapping. After edge processing of the PCB board 100 in the clamped state, the PCB board 100 is conveyed into the mounting frame 5 by the conveyor gripper. The ion water sprayer 17 rinses the surface of the PCB board 100 to remove debris. Then, the dryer 19 quickly dries it from both sides to ensure its surface cleanliness. The debris and wastewater generated during processing fall into the bottom collection box 20 through the gaps in the conveyor belt, realizing centralized waste treatment.
[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
