Description

Technical Field

[0001] This utility model relates to a conveying and positioning device, and more particularly to an automatic edge-wrapping conveying and positioning device for drilling holes in PCB copper-clad laminates. Background Technology

[0002] Copper-clad laminate (PCB) is the basic material for manufacturing printed circuit boards. It consists of one or more layers of insulating substrate and copper foil attached thereto, used to form circuit patterns and provide electrical connection paths. During the production process, the PCB needs to be edge-wrapped, and then the edge-wrapped PCB is conveyed to a designated location for drilling.

[0003] During the edge-wrapping process, the insulating substrate is usually placed manually in the work area, and then the copper foil is placed on the insulating substrate manually. The edge-wrapping machine is then used to wrap the edges, and finally the edge-wrapped PCB copper-clad board is conveyed to the designated position for drilling. Manual operation is slow and inefficient. Moreover, when placing the insulating substrate, it is necessary to manually position the insulating substrate, which takes a long time and further reduces work efficiency. Utility Model Content

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0027] Reference Figures 1-5An automatic edge-wrapping conveying and positioning device for drilling holes in PCB copper-clad laminates includes a base plate 1, a mounting platform 2, an electric guide rail 3, a placement plate 4, a placement shaft 5, a spring 6, an edge-wrapping machine 7, and a feeding mechanism. The mounting platform 2 is bolted to the top of the base plate 1. The electric guide rail 3 is bolted to the middle of the top of the mounting platform 2. The top of the slider of the electric guide rail 3 is bolted to the placement plate 4. The placement shaft 5 is slidably connected to the placement plate 4 at even intervals. Each placement shaft 5 is fitted with a spring 6. The two ends of the spring 6 are connected to the placement plate 4 and the placement shaft 5, respectively. Five edge-wrapping machines 7 are bolted to the top right side of the base plate 1. The feeding mechanism is used to place the insulating substrate and copper foil onto the placement shaft 5.

[0028] Reference Figure 1 , Figure 4 and Figure 5 The feeding mechanism includes a scissor-type telescopic frame 8, a lifting plate 9, a box 10, an electric guide rail 11, a moving frame 12, an electric push rod 13, and an electric suction cup 14. The scissor-type telescopic frame 8 is bolted to both the front and rear sides of the right side of the base plate 1. The lifting plate 9 is connected to the top of the scissor-type telescopic frame 8. The box 10 is bolted to the top right side of the base plate 1. The electric guide rail 11 is bolted to both the front and rear sides of the box 10. The moving frame 12 is bolted to the bottom of the slider of the electric guide rail 11. The electric push rod 13 is symmetrically installed on both the front and rear sides of the moving frame 12. The lower end of the telescopic rod of the electric push rod 13 is bolted to the electric suction cup 14.

[0029] The worker places a stack of insulating substrate on the front lifting plate 9, then places a stack of copper foil on the rear lifting plate 9. Next, the worker controls the extension of the telescopic rod of the front electric push rod 13, causing the front electric suction cup 14 to move downwards, contacting and holding the insulating substrate. Then, the worker controls the extension of the telescopic rod of the front electric push rod 13, causing the front electric suction cup 14 to move upwards, lifting the insulating substrate. Finally, the worker controls the front electric guide rail 11 to move the front movable frame 12 backwards, which in turn moves the insulating substrate backwards, moving it to the placement plate. Above 4, the electric suction cup 14 on the front side releases the insulating substrate, and the insulating substrate falls onto the placement shaft 5. This operation is repeated to place the copper foil on the insulating substrate. The automatic feeding and positioning of the insulating substrate and copper foil can reduce manual operation and thus improve work efficiency. Then, the edge banding machine 7 is controlled to band the edge of the insulating substrate to make a PCB copper-clad board. Spring 6 can buffer the force applied by the edge banding machine 7 to avoid damage to the insulating substrate. Then, the electric guide rail 3 is controlled to drive the placement plate 4 to move to the left. The placement plate 4 drives the PCB copper-clad board to move to the left and conveys the PCB copper-clad board to the designated position for drilling.

[0030] Reference Figures 6-8It also includes a pressing mechanism, which comprises an electric guide rail 15, a connecting frame 16, a horizontal plate 17, a slide bar 18, a sliding plate 19, an electric push rod 20, a slide bar 21, a spring 211, a sliding frame 22, and a ball bearing 23. The electric guide rail 15 is bolted to the top and both sides of the housing 10. The bottom of the slider of the electric guide rail 15 is bolted to the connecting frame 16. The bottom of the two connecting frames 16 is bolted to the horizontal plate 17. An opening (not marked) is provided in the middle right side of the housing 10 for the horizontal plate 17 to pass through. Figure 10 As can be seen from the image, sliding rods 18 are slidably connected to the left and right sides of the bottom of the horizontal plate 17. Slide plates 19 are connected to the bottom of sliding rods 18. Electric push rods 20 are bolted to the left and right sides of the bottom of the horizontal plate 17. The telescopic rods of electric push rods 20 are connected to slide plates 19. Sliding rods 21 are slidably connected to the left and right sides of slide plates 19. Springs 211 are fitted on sliding rods 211. The two ends of springs 211 are connected to slide plates 19 and sliding rods 211 respectively. The lower ends of the two sliding rods 21 on the same slide plate 19 are connected to a sliding frame 22. Ball bearings 23 are evenly spaced and rotated on the sliding frame 22.

[0031] The operator controls the electric guide rail 15 to move the connecting frame 16 to the right. The connecting frame 16 moves the horizontal plate 17 to the right. The horizontal plate 17 moves out of the box 10 through the opening on the right side of the box 10 to avoid collision between the moving frame 12 and the horizontal plate 17. After the copper foil is placed on the insulating substrate, the operator controls the electric guide rail 15 to move the connecting frame 16 to the left. The connecting frame 16 moves the horizontal plate 17 to the left. The horizontal plate 17 moves the ball bearing 23 to the left. The ball bearing 23 will contact the copper foil. Through the action of the spring 211, the ball bearing 23 can press the copper foil to ensure that the copper foil can adhere to the insulating substrate and prevent the position of the copper foil from shifting. Then, the operator controls the electric push rod 20 to extend, which moves the two sliding plates 19 in a direction away from each other, so that the ball bearing 23 rolls on the copper foil and presses other areas of the copper foil.

[0032] Reference Figure 9 It also includes a positioning mechanism, which includes a positioning block 24, a connecting rod 25, a connecting plate 26, and a screw 27. The positioning blocks 24 are symmetrically slidably connected to the left and right sides of the lifting plate 9. The connecting rods 25 are connected to the positioning blocks 24. The screws 27 are rotatably connected to the left and right sides of the bottom of the lifting plate 9. The connecting plates 26 are connected to the screws 27 by threads. The connecting plates 26 and the connecting rods 25 are connected.

[0033] Workers place the insulating substrate and copper foil onto the lifting plate 9. The positioning block 24 can position the insulating substrate and copper foil to prevent them from shifting. Rotating the screw 27 can move the connecting plate 26 and the connecting rod 25. The connecting rod 25 moves the positioning block 24. Adjusting the distance between the positioning blocks 24 on the left and right sides can be done according to the length of the insulating substrate and copper foil to accommodate insulating substrates and copper foils of different lengths.

[0034] Reference Figure 10 It also includes a transparent plate 28. The upper right side of the box 10 is connected to the transparent plate 28, which allows the insulating substrate and copper foil inside the box 10 to be seen through the transparent plate 28, making it easy to understand the condition of the insulating substrate and copper foil.
