Description

Technical Field

[0001] This utility model relates to the technical field of circuit board drilling devices, specifically a printed circuit board drilling device with a waste collection structure. Background Technology

[0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. During the processing of circuit boards, holes need to be punched in them using a drilling device.

[0003] For example, in the announcement number CN216067805U, a drilling device for circuit board processing collects circuit board debris from the collection section into a collection filter box through a debris collection device. The collection section collects the debris from the upper side of the circuit board when the CNC drilling device drills holes in the circuit board, and the debris collection box collects the debris from the lower side of the circuit board. By collecting the debris generated during circuit board drilling, the processing environment is kept clean and tidy.

[0004] The above solution collects waste generated during drilling by setting a first collection box at the bottom. However, since the collection box is fixed and the same position is used when drilling the same batch of circuit boards, most of the waste will accumulate in the same position in the collection box, which can easily cause the waste to overflow. Furthermore, the other space in the collection box cannot be effectively utilized. When the collection box is pulled out, some of the accumulated waste will also come into contact with the workbench and fall into the workbench, requiring secondary cleaning by the staff. Utility Model Content

[0005] The purpose of this invention is to provide a printed circuit board drilling device with a waste collection structure, so as to solve the problem mentioned in the background art that the existing printed circuit board drilling devices are not convenient for efficient collection of waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printed circuit board drilling device with a waste collection structure, comprising a body and a rotating rod. A hydraulic cylinder is installed inside the body, and a drilling machine is installed at the bottom of the hydraulic cylinder. A worktable is fixed to one side of the body, and a movable plate is slidably connected to the top of the worktable via a slide rail. A movable frame a is slidably connected to the top of the movable plate via a slide rail. A vertical rod is fixed to one side of the drilling machine via a bracket, and a rotating rod is slidably connected to the bottom of the vertical rod. The bottom of the rotating rod is rotatably connected to the body via a bearing. A rotary drive mechanism is provided inside the rotating rod. A push rod body is slidably connected to the side of the worktable near the rotating rod. A collection box is inserted inside the worktable, and the bottom of the collection box abuts against the movable frame b. A reciprocating motion mechanism is provided on one side of the movable frame b, and a guide mechanism is provided at the bottom of the movable frame b. A threaded rod is threadedly connected to both sides of the movable frame a, and a limit mechanism is provided at one end of the movable frame a.

[0007] Furthermore, an electric push rod a is fixed to one side of the movable plate, and one side of the electric push rod a is fixed to the worktable. An electric push rod b is connected to one side of the movable frame a, and one side of the electric push rod b is fixed to the movable plate.

[0008] Furthermore, the rotary drive mechanism includes a protrusion fixedly connected to the bottom of the vertical rod, and a spiral groove is provided inside the rotating rod, with the inner side of the spiral groove slidably connected to the protrusion.

[0009] Furthermore, the reciprocating motion mechanism includes a spring sleeved on the outside of the push rod body, with one end of the spring abutting against the worktable. One end of the push rod body is rotatably connected to a roller via a rotating shaft, and one end of the push rod body is provided with a cam, the inner side of which is fixed to the rotating rod.

[0010] Furthermore, the guiding mechanism includes a round rod rotatably connected to the bottom of the movable frame b via a rotating shaft, a guide groove is provided at the bottom of the worktable, and the inner side of the guide groove is slidably connected to the round rod, and the guide groove has a wavy shape.

[0011] Furthermore, the limiting mechanism includes a pressure plate rotatably connected to one end of a threaded rod via a bearing. A rubber pad is fixedly connected to one side of the pressure plate, and two sets of sliding rods are fixed to the other side of the pressure plate. The outer side of the sliding rods is slidably connected to the movable frame a.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the printed circuit board drilling device with a waste collection structure can trigger the rotation drive mechanism to move when the hydraulic cylinder drives the drilling machine to move down to drill holes, so that the cam rotates. When the cam rotates, it will trigger the reciprocating motion mechanism, thereby causing the collection box to shake, mixing the waste collected in the collection box, making full use of the space in the collection box, and the limiting mechanism can stably limit the circuit board placed in the moving frame a.

[0013] 1. By starting the hydraulic cylinder, the drilling machine is driven to drill holes in the circuit board. The vertical rod moves down synchronously, driving the rotating rod and cam to rotate. This causes the reciprocating motion structure to drive the moving frame b to move back and forth. When the moving frame b moves, it is guided by the guide groove, thus making it swing back and forth in another direction to prevent waste from accumulating in the collection box.

[0014] 2. By rotating the threaded rod and moving frame a, the pressure plate at the end is moved. When the rubber pads on one side of both pressure plates are in contact with one side of the circuit board, the circuit board can be limited. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a printed circuit board drilling device with a waste collection structure, including a body 1 and a rotating rod 8. A hydraulic cylinder 2 is installed inside the body 1, and a drilling machine 3 is installed at the bottom of the hydraulic cylinder 2. A workbench 4 is fixed on one side of the body 1. A movable plate 5 is slidably connected to the top of the workbench 4 via a slide rail. A movable frame a6 is slidably connected to the top of the movable plate 5 via a slide rail. A vertical rod 7 is fixed to one side of the drilling machine 3 via a bracket. A rotating rod 8 is slidably connected to the bottom of the vertical rod 7. The bottom of the rotating rod 8 is rotatably connected to the body 1 via a bearing. A rotation drive mechanism is provided inside the rotating rod 8. A push rod body 20 is slidably connected to the side of the workbench 4 near the rotating rod 8. A collection box 14 is inserted into the inside of the workbench 4. The bottom of the collection box 14 abuts against a movable frame b13. A reciprocating motion mechanism is provided on one side of the movable frame b13, and a guide mechanism is provided at the bottom of the movable frame b13. An electric push rod a is fixed to one side of the movable plate 5, and the electric push rod a6 is slidably connected to the workbench 4. One side of the push rod a is fixed to the worktable 4, and one side of the moving frame a6 is connected to the electric push rod b, and one side of the electric push rod b is fixed to the moving plate 5; the rotary drive mechanism includes a protrusion 10 fixedly connected to the bottom of the vertical rod 7, and a spiral groove 11 is opened inside the rotating rod 8, and the inner side of the spiral groove 11 is slidably connected to the protrusion 10; the reciprocating motion mechanism includes a spring 12 sleeved on the outside of the push rod body 20, and one end of the spring 12 abuts against the worktable 4, one end of the push rod body 20 is rotatably connected to a roller through a rotating shaft, one end of the push rod body 20 is provided with a cam 9, and the inner side of the cam 9 is fixed to the rotating rod 8, and the inside of the worktable 4 is provided with a sliding groove that matches the push rod body 20, and the push rod body 20 and the worktable 4 form a sliding structure; the guide mechanism includes a round rod 15 rotatably connected to the bottom of the moving frame b13 through a rotating shaft, and a guide groove 16 is opened at the bottom of the worktable 4, and the inner side of the guide groove 16 is slidably connected to the round rod 15, and the guide groove 16 has a wavy shape.

[0025] Please see Figures 1-6This printed circuit board drilling device, equipped with a waste collection structure, works by moving the drilling machine 3 downwards via the hydraulic cylinder 2 during drilling. When the drill bit in the drilling machine 3 contacts the circuit board in the moving frame a6, it drills a hole. Activating the electric push rod a moves the moving frame a6 in one direction, and activating the electric push rod b moves the moving plate 5 and the moving frame a6 in the other direction, thus adjusting the drilling position on the circuit board. The waste generated during drilling falls into the collection box 14. To prevent waste from accumulating in certain areas of the collection box 14, a set of vertical rods 7 is installed on one side of the drilling machine 3. When the drilling machine 3 moves downwards to drill, it also moves the vertical rods 7 downwards. The vertical rods 7 are located inside the rotating rod 8 via the bottom protrusion 10. The spiral groove 11 slides, thereby driving the rotating rod 8 to rotate. When the rotating rod 8 rotates, it will drive the bottom cam 9 to push the push rod body 20, so that the push rod body 20 will squeeze the spring 12 sleeved on the outside. The push rod body 20 can push the movable frame b13 at one end to move through the slider. When the movable frame b13 moves, the bottom round rod 15 will slide in the guide groove 16. The guide groove 16 can guide the round rod 15 and the movable frame b13, so that the movable frame b13 will swing back and forth in another direction when pushed by the push rod body 20, thereby making the waste collected in the top collection box 14 evenly mixed and preventing it from accumulating in some positions. In this way, the waste generated by the drilling device can be collected through the collection box 14 through the above operation, and the space in the collection box 14 can be fully utilized.

[0026] Example 2:

[0027] Please see Figures 2-3 Based on Embodiment 1, a circuit board fixing structure in the circuit board drilling device is also disclosed, the specific structure of which is as follows: a threaded rod 17 is threadedly connected to both sides of the movable frame a6, and a limiting mechanism is provided at one end of the movable frame a6. The limiting mechanism includes a pressure plate 19 rotatably connected to one end of the threaded rod 17 through a bearing. A rubber pad is fixedly connected to one side of the pressure plate 19, and two sets of sliding rods 18 are fixed to the other side of the pressure plate 19. The outer side of the sliding rod 18 is slidably connected to the movable frame a6. Through holes matching the sliding rods 18 are opened on both sides of the movable frame a6. The sliding rods 18 and the movable frame a6 form a sliding structure, and the threaded rod 17 and the movable frame a6 form a threaded transmission structure.

[0028] Please see Figures 2-3The printed circuit board drilling device with a waste collection structure needs to fix the circuit board when drilling. By rotating the threaded rod 17 and the moving frame a6 for threaded transmission, the pressure plate 19 at the end is moved. Two sets of sliding rods 18 on one side of the pressure plate 19 slide in the moving frame a6 to keep the pressure plate 19 moving smoothly. When the rubber pads on both sides of the pressure plate 19 are in contact with one side of the circuit board, the circuit board can be limited. At this time, the circuit board can be drilled stably. The rubber pads can prevent hard contact with the circuit board and damage to the circuit board. In this way, the circuit board can be limited for processing.
