Description

TECHNICAL FIELD

[0001] The utility model relates to a covering device, especially a covering device for PCB copper-clad plate drilling. BACKGROUND

[0002] PCB, full name printed circuit board, is an assembly board that realizes the electrical connection between electronic components by printing conductive lines and connecting points on an insulating substrate according to a predetermined circuit pattern. As a basic component of modern electronic equipment, it carries electronic components and promotes signal transmission and functional cooperation between them, and is widely used in communication, medical treatment, industrial control, automobile electronics, household appliances, aerospace and computers.

[0003] In the PCB manufacturing process, multi-layer boards including copper-clad plates need to be drilled. Before drilling, the multi-layer boards including copper-clad plates are usually aligned by hand, and the aligned multi-layer boards are covered to ensure the accuracy of drilling. However, this manual covering method requires workers to place and align the boards one by one on the drilling equipment, resulting in low work efficiency and high labor cost.

[0004] Therefore, it is necessary to design a covering device for PCB copper-clad plate drilling. UTILITY MODEL CONTENT

[0005] In order to overcome the shortcomings of traditional covering methods, which are mostly manual operation and have low work efficiency, the technical problem to be solved is to provide a covering device for PCB copper-clad plate drilling.

[0006] The technical solution of the utility model is: a covering device for PCB copper-clad plate drilling, comprising an operation table, a limiting plate fixedly connected to the top of the operation table, an electric sliding rail provided on the operation table, a fixed rod fixedly connected to the sliding block of the electric sliding rail, a rotating rod rotatably connected to the fixed rod, a roller rotatably connected to the fixed rod and the rotating rod, a glue feeding assembly provided on the limiting plate for feeding adhesive tape, and a lifting assembly provided on the operation table for lifting workpieces.

[0007] In one embodiment, the limiting plate is fixedly connected on one side to a fixing member for fixing workpieces.

[0008] In one embodiment, the operation table is fixedly connected on one side to a conveying frame, a conveying roller is rotatably connected to the conveying frame, and a drive motor is installed on one side of the conveying frame, the output shaft of the drive motor penetrates through the conveying frame and is connected to the conveying roller.

[0009] In one embodiment, a spring is provided between the fixed rod and the rotating rod, and the two ends of the spring are respectively connected to the fixed rod and the rotating rod.

[0010] In one embodiment, the adhesive feeding assembly includes a fixing plate and a mounting frame. The fixing plate is fixedly connected to the top of the limiting plate, and the mounting frame is fixedly connected to one side of the limiting plate. A motor is mounted on the mounting frame, and a roller is rotatably connected to the mounting frame. The output shaft of the motor is connected to the roller, and a blade for cutting the adhesive tape is fixedly connected to the bottom of the mounting frame.

[0011] In one embodiment, the lifting assembly includes a support frame fixedly connected to the bottom of the operating table, a cylinder mounted on the support frame, and a piston rod of the cylinder passing through the operating table and connected to a push plate.

[0012] The beneficial effects of this utility model are: 1. Through the design of electric slide rail, fixed rod, rotating rod and roller, combined with push plate and fixing parts, this utility model can accurately carry out the edge binding work, ensure the high-quality completion of the edge binding work, reduce manual intervention, greatly shorten the edge binding time and improve production efficiency.

[0013] 2. This utility model utilizes the restorative property of the spring to ensure that the rollers on the rotating rod maintain close contact with the multilayer board. Even when the multilayer board passes through the gap between the rollers, it can ensure a tight fit between the tape and the multilayer board, effectively preventing the tape from loosening and improving the stability and reliability of the edge-wrapping work.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example: An edge-wrapping device for drilling holes in copper-clad laminates of PCBs, such as... Figures 1-4 As shown, the system includes an operating table 1, with a limiting plate 101 fixedly connected to the top of the operating table 1. An electric slide rail 3 is provided on the operating table 1, and a fixed rod 4 is fixedly connected to the slider of the electric slide rail 3. A rotating rod 5 is rotatably connected to the fixed rod 4 and the rotating rod 5. Rollers 6 are rotatably connected to both the fixed rod 4 and the rotating rod 5. A glue feeding assembly for conveying tape is provided on the limiting plate 101. A lifting assembly for lifting workpieces is provided on the operating table 1. The lifting assembly includes a support frame 9 fixedly connected to the bottom of the operating table 1. A cylinder 901 is mounted on the support frame 9. The piston rod of the cylinder 901 passes through the operating table 1 and is connected to a push plate 902. When the cylinder 901 is activated, the piston rod extends outward, causing the push plate 902 to move upward. The push plate 902 vertically lifts the workpiece placed above until it contacts the fixing component 102, thus completing the workpiece fixing process.

[0023] like Figures 1-2 As shown, a fixing member 102 for fixing the workpiece is fixedly connected to one side of the limiting plate 101. Here, the design of the fixing member 102 can cooperate with the lifting push plate 902 so that the fixing member 102 and the push plate 902 can jointly clamp and fix the multi-layer board, prevent the multi-layer board from shifting, and ensure the quality and efficiency of the edge banding work.

[0024] like Figure 1 As shown, a conveyor frame 2 is fixedly connected to one side of the operating table 1. A conveyor roller 201 is rotatably connected to the conveyor frame 2. A drive motor 202 is installed on one side of the conveyor frame 2. The output shaft of the drive motor 202 passes through the conveyor frame 2 and is connected to the conveyor roller 201. Here, when the drive motor 202 is started, the drive motor 202 drives the output shaft to rotate. The output shaft of the drive motor 202 drives the conveyor roller 201 to rotate. Through the rotating conveyor roller 201, the multi-layer board with the edge banding completed can be automatically conveyed, reducing manual transportation costs and improving work efficiency.

[0025] like Figure 4As shown, a spring 7 is provided between the fixed rod 4 and the rotating rod 5. The two ends of the spring 7 are respectively connected to the fixed rod 4 and the rotating rod 5. Here, when the multilayer board passes through the gap between the rollers 6 on the fixed rod 4 and the rotating rod 5, the rollers 6 on the rotating rod 5 are located at the top of the multilayer board, and the rollers 6 on the fixed rod 4 are located at the bottom of the multilayer board. At this time, the spring 7 is stretched. At the same time, the spring 7 uses its restorative property to apply a pulling force to the rotating rod 5. The spring 7 pulls the rotating rod 5, so that the rollers 6 on the rotating rod 5 keep in contact with the multilayer board, thereby ensuring the tightness of the edge binding work and preventing the tape from coming loose.

[0026] like Figure 2 and Figure 5 As shown, the adhesive feeding assembly includes a fixed plate 8 and a mounting bracket 802. The fixed plate 8 is fixedly connected to the top of the limiting plate 101, and the mounting bracket 802 is fixedly connected to one side of the limiting plate 101. A motor 801 is mounted on the mounting bracket 802, and a roller 803 is rotatably connected to the mounting bracket 802. The output shaft of the motor 801 is connected to the roller 803. A blade 804 for cutting adhesive tape is fixedly connected to the bottom of the mounting bracket 802. Here, when the motor 801 is started, the motor 801 drives the output shaft to rotate, and the output shaft of the motor 801 drives the roller 803 to rotate, causing the two rollers 803 to rotate. 03. The two rollers 803 rotate in opposite directions, conveying the tape movably mounted on the fixed plate 8. The tape is then conveyed to the front of the fixed rod 4 and the rotating rod 5. Then, the electric slide rail 3 is activated, driving the slider to slide inward. The slider of the electric slide rail 3 drives the connected fixed rod 4 to move inward. The fixed rod 4 drives the rotating rod 5 to move inward, which in turn drives the rollers 6 on the fixed rod 4 and the rotating rod 5 to move inward. During the movement, the rollers 6 push the tape inward, making the tape contact the side wall of the multilayer board. At the same time, the tape is pushed by the rollers 6 and squeezes the blade 804 on the mounting bracket 802, cutting the tape.

[0027] This device is used in the drilling process of PCB boards to stack multilayer boards and perform edge binding. In use, the multilayer boards are placed on the operating table 1 and aligned using the limiting plate 101 fixed to the operating table 1. Then, cylinder 901 is activated, extending its piston rod outwards. The piston rod drives the push plate 902 upwards, vertically lifting the multilayer boards until they contact the fixing member 102. The fixing member 102 limits and fixes the multilayer boards. Next, motor 801 is activated, driving the output shaft to rotate. The output shaft of motor 801 drives rollers 803 to rotate, causing the two rollers 803 to rotate in opposite directions. The rotation of the two rollers 803 conveys the tape movably mounted on the fixing plate 8 to the area directly in front of the fixing rod 4 and the rotating rod 5. Then, the electric slide rail 3 is activated, driving the slider to slide inward. The slider of the electric slide rail 3 drives the connected fixed rod 4 to move inward, which in turn drives the rotating rod 5 to move inward, thereby driving the rollers 6 on the fixed rod 4 and the rotating rod 5 to move inward. During the movement, the rollers 6 push the tape inward, making the tape contact the side wall of the multilayer board. At the same time, the tape is pushed by the rollers 6 and squeezes the blade 804 on the mounting bracket 802, cutting the tape. Then, the rollers 6 continue to move inward, and the multilayer board passes through the gap between the fixed rod 4 and the rollers 6 on the rotating rod 5, so that the rollers 6 on the rotating rod 5 contact the top of the multilayer board, and the rollers 6 on the fixed rod 4 contact the bottom of the multilayer board. At the same time, the rollers 6 squeeze the tape when they contact the multilayer board, making the tape completely adhere to the multilayer board, thus completing the edge wrapping work of the multilayer board.
