Description

Technical Field

[0001] This utility model belongs to the field of PCB board drilling technology, and in particular relates to a PCB board drilling device. Background Technology

[0002] A PCB, or Printed Circuit Board, is a component that provides electrical connections for electronic components. PCBs are classified by the number of layers: single-sided, double-sided, four-layer, six-layer, and other multi-layer types. During PCB manufacturing, drilling is required to facilitate connections and installation. This drilling process necessitates the use of drilling equipment to create holes in the PCB.

[0003] Some PCB drilling devices on the market generate a lot of suspended debris during PCB drilling, which may affect the processing accuracy and cause inconvenience when scattered on the equipment. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a PCB board drilling device. A collection groove is opened at the top of the drilling table to collect debris that falls naturally during the drilling process. A slider in the sliding groove at the bottom of the drilling table is fixedly connected to the collection box, which is located directly below the collection groove. The collection box can be slidably pulled along the sliding groove to periodically clean the collected debris. A vacuum cleaner on the rear side of the drilling table is connected to a suction ring through a suction pipe. The inside of the suction ring is connected to the suction pipe to form a negative pressure channel. During drilling, the vacuum cleaner is activated to generate negative pressure. The dust and debris generated during drilling are adsorbed by the suction ring and transported to the vacuum cleaner for storage through the suction pipe. This actively removes suspended debris and prevents it from scattering and contaminating the equipment, thus affecting the processing accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB board drilling device, including a drilling table, with fixed frames slidably connected to both sides of the drilling table, fixed sleeves slidably connected to the surface of the fixed frames, an electric telescopic rod at the bottom of the fixed sleeve, a drill bit at the bottom of the electric telescopic rod, a collection box at the top of the drilling table, two sliding grooves at the bottom of the drilling table, sliders slidably connected inside the sliding grooves, a collection box fixedly connected to the bottom of each of the two sliders, two guide rails fixedly connected to the top of the drilling table, two guide blocks slidably connected to the surface of the guide rails, the four guide blocks divided into two groups, a first clamping plate fixedly connected to the top of each group of two guide blocks, two first electric push rods on the first clamping plate, a second clamping plate fixedly connected to the top of each of the two electric push rods, a vacuum cleaner fixedly connected to the rear side of the drilling table, a vacuum cleaner with a vacuum pipe, and a vacuum ring at the end of the vacuum pipe away from the vacuum cleaner.

[0006] Furthermore, the interior of the suction ring is connected to the interior of the suction tube.

[0007] Furthermore, the collection box is located directly below the collection trough.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The collection groove at the top of the drilling table is used to collect the debris that falls naturally during drilling. The slider in the slide groove at the bottom of the drilling table is fixedly connected to the collection box. The collection box is located directly below the collection groove and can be slidably pulled out along the slide groove to clean the collected debris periodically. The vacuum cleaner at the rear of the drilling table is connected to the suction ring through the suction pipe. The inside of the suction ring is connected to the suction pipe to form a negative pressure channel. When drilling is performed, the vacuum cleaner is activated to generate negative pressure. The dust and debris generated during drilling are adsorbed by the suction ring and transported to the vacuum cleaner for storage through the suction pipe. This actively removes suspended debris and prevents it from scattering and contaminating the equipment, which could affect the processing accuracy. Attached Figure Description

[0015] See appendix Figure 1-2As shown, a PCB board drilling device includes a drilling table 1, with fixed frames 13 slidably connected to both sides of the drilling table 1. Fixed sleeves are slidably connected to the surface of the fixed frames 13. An electric telescopic rod is provided at the bottom of the fixed sleeve, and a drill bit is provided at the bottom of the electric telescopic rod. A collection box 3 is provided at the top of the drilling table 1. Two sliding grooves are provided at the bottom of the drilling table 1, and sliders 2 are slidably connected inside the sliding grooves. The collection box 3 is fixedly connected to the bottom of the two sliders 2. Two guide rails 5 are fixedly connected to the top of the drilling table 1. Two guide blocks 6 are slidably connected to the surface of the guide rails 5. The four guide blocks 6 are divided into two groups. A first clamping plate 7 is fixedly connected to the top of the two guide blocks 6 in each group. Two first electric push rods 8 are provided on the first clamping plate 7. A second clamping plate 9 is fixedly connected to the top of the two electric push rods 8. A vacuum cleaner 10 is fixedly connected to the rear side of the drilling table 1. A vacuum cleaner pipe 11 is provided on the vacuum cleaner 10. A vacuum cleaner ring 12 is provided at the end of the vacuum cleaner pipe 11 away from the vacuum cleaner 10.

[0016] The inside of the suction ring 12 is connected to the inside of the suction tube 11.

[0017] Collection box 3 is located directly below collection slot 4.

[0018] Working principle: The guide rail 5 at the top of the drilling table 1 provides a sliding track for the guide block 6. The sliding of the guide block 6 on the guide rail 5 drives the two sets of first clamping plates 7 to move synchronously, achieving initial positioning of the PCB board in the width direction. When the first electric push rod 8 on the first clamping plate 7 extends, it pushes the second clamping plate 9 at the top towards the PCB board surface. Through the upper and lower clamping structure of the first clamping plate 7 and the second clamping plate 9, the PCB board is fixed vertically, ensuring no workpiece displacement during drilling. The fixing sleeve slides along the surface of the fixing frame 13, adjusting the horizontal position of the drill. The extension and retraction of the electric telescopic rod drives the drill to move up and down, achieving the positioning of the PCB board. The drilling process of the plate is carried out through the linkage of the fixed frame 13, the fixed sleeve, and the electric telescopic rod. The drill can cover the processing area above the drilling table 1 to complete the drilling needs of multiple positions. The collection groove 4 opened at the top of the drilling table 1 is used to collect the debris that falls naturally during the drilling process. The slider 2 in the sliding groove at the bottom of the drilling table 1 is fixedly connected to the collection box 3. The collection box 3 is located directly below the collection groove 4 and can be slid and pulled along the sliding groove to clean the collected debris regularly. The vacuum cleaner 10 on the rear side of the drilling table 1 is connected to the suction ring 12 through the suction pipe 11. The inside of the suction ring 12 is connected to the suction pipe 11 to form a negative pressure channel. When drilling, the vacuum cleaner 10 is started to generate negative pressure. The dust and debris generated by drilling are adsorbed by the suction ring 12 and transported to the vacuum cleaner 10 for storage through the suction pipe 11. The suspended debris is actively removed to prevent it from scattering and contaminating the equipment and affecting the processing accuracy.
