Description
Technical Field
[0001] This utility model relates to the field of PCB board processing technology, and in particular to a drill bit upper ring device. Background Technology
[0002] PCB boards, also known as circuit boards, are used to support, fix, and connect electronic components, and to interconnect electronic components through different forms of circuits. They are widely used in various electrical appliances and automated equipment.
[0003] Drilling is a critical step in the PCB manufacturing process, as it is used not only to fix electronic components but also for circuit connections. Depending on the requirements, the inner diameter of the drilled hole can range from a few millimeters to tens of millimeters, using different sized drill bits. Therefore, on the processing table of automated equipment, it is necessary to change drill bits efficiently and ensure that the robotic arm can quickly identify and select the appropriate drill bit.
[0004] To address the issue of rapid drill bit changeover, the production line employs ring sleeves of different colors and patterns, each designed to accommodate different drill bit sizes. For example, a red ring sleeve is used for 5mm drill bits, while a blue ring sleeve is used for 10mm drill bits. The robotic arm is equipped with a color-detecting camera, allowing it to quickly select the appropriate drill bit based on the color of the ring sleeve. When a drill bit change is needed, the robotic arm retrieves the corresponding drill bit from the tool magazine chuck based on the camera's recognition result.
[0005] However, when these drill bits need to be moved from one automated equipment's workbench to another, the original annular sleeves are no longer suitable because the automated equipment is incompatible. The existing annular sleeves must be removed and replaced with ones that are the right color and size for the new equipment. For example, the red annular sleeves on a 5mm drill bit need to be replaced with blue annular sleeves.
[0006] However, due to the large number of drill bits originally placed on the chuck, manually changing the annular sleeve is cumbersome and time-consuming, reducing production efficiency. Utility Model Content
[0007] The purpose of this invention is to solve the problem that in the existing technology, when there are a large number of drill bits placed on the chuck, it is cumbersome and time-consuming to manually change the annular sleeve, which reduces production efficiency. Therefore, this invention proposes a drill bit upper ring device.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A drill bit upper ring device includes a worktable, a turntable rotatably connected to the worktable, a support plate fixedly connected to the turntable, and a placement hole on the support plate. The device further includes: a disassembly cylinder jacked and raised on the worktable, wherein the disassembly cylinder has a negative pressure suction hole, and the axis of the negative pressure suction hole is parallel to the axis of the placement hole; and a mounting frame fixedly connected to the worktable, wherein an extrusion cylinder is jacked and raised on the mounting frame, and the mounting frame has a discharge port, the axis of which is parallel to the axis of the extrusion cylinder.
[0010] To facilitate the displacement and lifting of the disassembly cylinder, preferably, a fixed platform is fixedly connected to the workbench, a first telescopic member is fixedly connected to the fixed platform, and the disassembly cylinder is fixedly connected to the output end of the first telescopic member.
[0011] In order to generate negative pressure in the negative pressure suction hole, a negative pressure pump is further fixedly connected to the workbench, and the input end of the negative pressure pump is connected to the negative pressure suction hole through a telescopic tube.
[0012] To facilitate the displacement and lifting of the extrusion cylinder, preferably, a second telescopic component is fixedly connected to the mounting frame, and the extrusion cylinder is fixedly connected to the output end of the second telescopic component.
[0013] To facilitate the conveying of the annular sleeve, preferably, a discharge box is fixedly connected to the mounting frame, and the discharge box is disposed between the extrusion cylinder and the support plate.
[0014] To facilitate the rotation of the turntable, preferably, a motor is fixedly connected to the worktable, and the turntable is fixedly connected to the output end of the motor.
[0015] To facilitate support of the drill bit, preferably, a limiting ring is fixedly connected to the worktable, and the limiting ring is located below the support plate.
[0016] To facilitate clamping and limiting the drill bit, preferably, a clamping plate is provided on the worktable. When the bottom of the disassembly cylinder abuts against the surface of the annular sleeve on the drill bit, the drill bit is limited by the clamping plate.
[0017] Compared with the prior art, the present invention provides an upper ring device for a drill bit, which has the following advantages:
[0018] 1. The upper ring device of the drill bit, through the first telescopic component, drives the disassembly cylinder to move downward toward the original annular sleeve. Then, the disassembly cylinder abuts against the top of the original annular sleeve. Then, the first telescopic component drives the disassembly cylinder to move upward, thereby disassembling the original annular sleeve and detaching it from the drill bit. This allows for quick and convenient disassembly of the drill bit with the original annular sleeve, reducing the need for manual operation. It is suitable for high-frequency production scenarios and improves overall work efficiency and safety.
[0019] 2. The upper ring device of the drill bit can drive the extrusion cylinder to descend through the second telescopic component, fix the annular sleeve on the drill bit, and complete the upper ring of the drill bit. Then, the robot arm will clamp and move the assembled drill bit after completion, thereby significantly improving the installation speed of the annular sleeve and improving production efficiency.
[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model can quickly disassemble the old annular sleeve on the drill bit and significantly improve the installation speed of the new annular sleeve, thereby increasing production efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] Example:
[0029] Reference Figure 1 - Figure 4 A drill bit upper ring device includes a worktable 5, a turntable 1 rotatably connected to the worktable 5, a support plate 2 fixedly connected to the turntable 1, and a placement hole 3 on the support plate 2. A motor 4, which is a stepper motor 4, is also provided on the worktable 5. The turntable 1 is fixedly connected to the output end of the motor 4. The support plate 2 is arranged in eight groups evenly distributed around the circumference, and the included angle between each group of support plates 2 is 45°. The motor 4 rotates by 45° each time, so that the placement holes 3 of the front and rear support plates 2 are always kept in the same position. A limit ring 18 is fixedly connected to the worktable 5. The limit ring 18 is located below the support plate 2. When the drill bit is placed on the placement hole 3, the bottom of the drill bit can abut against the limit ring 18, thereby ensuring that the drill bit is at the same horizontal height.
[0030] A fixed platform 6 is also fixedly connected to the workbench 5. A first telescopic component 7 is fixedly connected to the fixed platform 6. The disassembly cylinder 8 is fixedly connected to the output end of the first telescopic component 7 and is used to drive the disassembly cylinder 8 to move up and down. The middle part of the disassembly cylinder 8 is hollow, so that the drill bit can extend into the cavity of the disassembly cylinder 8. A negative pressure suction hole 9 is opened on the disassembly cylinder 8, and the negative pressure suction hole 9 is parallel to the plane where the placement hole 3 is located. At the same time, the negative pressure suction hole 9 opened on the disassembly cylinder 8 can also abut against the top of the annular sleeve.
[0031] To ensure the stability of the disassembly cylinder 8 in disassembling the annular sleeve, a clamping plate 17 is provided on the workbench 5. When the bottom of the disassembly cylinder 8 abuts against the surface of the annular sleeve on the drill bit, the drill bit is limited and clamped by the inner walls of the two sets of clamping plates 17 and fixed to prevent the drill bit from shaking.
[0032] A negative pressure pump 11 is fixedly connected to the workbench 5. The input end of the negative pressure pump 11 is connected to the negative pressure suction hole 9 through the telescopic tube 10. When the support plate 2 rotates, the previous set of drill bits with annular sleeves can be moved to the bottom of the disassembly cylinder 8. At this time, the negative pressure pump 11 is started. The switch of the negative pressure pump 11 can be controlled by the control board. Negative pressure is generated in the negative pressure suction hole 9. The first telescopic component 7 drives the disassembly cylinder 8 to move downward toward the original annular sleeve. Then the disassembly cylinder 8 abuts against the top of the original annular sleeve. Then the first telescopic component 7 drives the disassembly cylinder 8 to move upward, thereby disassembling the original annular sleeve and detaching it from the drill bit. This allows for quick and convenient disassembly of the drill bit with the original annular sleeve, reducing the need for manual operation. This is suitable for high-frequency production scenarios and improves overall work efficiency and safety.
[0033] To facilitate the installation of a new annular sleeve on the drill bit, a mounting bracket 12 is fixedly connected to the worktable 5. A second telescopic member 13 is fixedly connected to the mounting bracket 12. A pressing cylinder 14 is fixedly connected to the output end of the second telescopic member 13. The second telescopic member 13 can drive the pressing cylinder 14 to move up and down. The pressing cylinder 14 is hollow in the middle, and the inner diameter of the hollow pressing cylinder 14 is larger than the diameter of the drill bit. The outer diameter of the pressing cylinder 14 is smaller than the diameter of the annular sleeve. For example, if the diameter of the drill bit is 5mm, the inner diameter of the hollow pressing cylinder 14 can be 6mm. When the diameter of the annular sleeve is 10mm, the outer diameter of the pressing cylinder 14 can be 9mm. In this case, the pressing cylinder 14 can press the annular sleeve.
[0034] A discharge port 16 is provided on the mounting frame 12, and the discharge port 16 is parallel to the plane of the extrusion cylinder 14. The diameter of the discharge port 16 is the same as the diameter of the annular sleeve. A discharge box 15 is fixedly connected to the mounting frame 12, and the discharge box 15 is located between the extrusion cylinder 14 and the support plate 2.
[0035] When the support plate 2 moves the drill bit below the discharge port 16, the annular sleeve is moved to the position of the discharge port 16. At this time, the annular sleeve is fitted onto the drill bit. The second telescopic component 13 can drive the extrusion cylinder 14 to descend, fix the annular sleeve on the drill bit, and complete the installation of the annular sleeve. Then, the robot arm will clamp and move the assembled drill bit, thereby significantly improving the installation speed of the annular sleeve and increasing production efficiency.
[0036] It should be explained that the aforementioned telescopic component can be an electric telescopic rod or a cylinder.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
