Description

Technical Field

[0001] This utility model relates to the field of rapid positioning technology, specifically a rapid positioning and hole-opening device for multilayer circuit board production. Background Technology

[0002] As electronic devices develop towards miniaturization and high performance, multilayer circuit boards, as an important carrier of electronic components, are receiving increasing attention for their manufacturing technology. In the production process of multilayer circuit boards, hole drilling is an essential key process, and the accuracy of hole positions and the quality of hole walls directly affect the electrical performance and reliability of the circuit board.

[0003] Traditional multilayer circuit board drilling equipment often uses drill bits with fixed angles. When drilling at different angles or positions, the workpiece needs to be re-clamped multiple times. This method not only consumes a lot of time and reduces production efficiency, but also easily introduces positioning errors during repeated clamping, resulting in a decrease in hole accuracy and affecting the quality of the circuit board.

[0004] In view of this, we propose a rapid positioning and drilling device for multilayer circuit board production. Utility Model Content

[0005] The purpose of this invention is to provide a rapid positioning and drilling device for multilayer circuit board production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid positioning and drilling device for multilayer circuit board production includes a frame, a platform fixedly mounted on the top of the frame, a moving component disposed on the frame, the moving component including a support plate, and a rotating mechanism disposed on the support plate, the rotating mechanism including:

[0008] The first hinge block is fixedly installed on the top of the support plate. The first hinge block is hinged to the fixed end of the hydraulic rod inside. The piston end of the hydraulic rod is hinged to the second hinge block. The outer wall of the second hinge block is fixedly installed on one side of the U-shaped frame. The other side of the U-shaped frame is fixedly installed on the outer wall of the tray.

[0009] The bottom outer wall of the support plate is fixedly installed with one end of the protrusion, and the other end of the protrusion is hinged to the side wall of the support plate.

[0010] An asynchronous motor is fixedly installed at the bottom of the tray. A rotating drum is fixedly installed at the output end of the asynchronous motor. The outer wall of the rotating drum is rotatably installed inside the tray via bearing components. A drill bit is slidably fitted inside the rotating drum. A limit groove is opened at the top of the drill bit. A limit block is threadedly fitted inside the outer wall of the rotating drum. The outer wall of the limit block is slidably fitted inside the limit groove.

[0011] In a further embodiment, the hydraulic rod is provided in two sets, which makes the rotation more stable.

[0012] In a further embodiment, the top of the drill bit is rectangular.

[0013] In a further embodiment, the limiting groove and the limiting block are matched in size.

[0014] In a further embodiment, an auxiliary mechanism is provided on the support plate. The auxiliary mechanism includes an air pump. The air pump is fixedly installed on the side wall of the support plate. An air inlet pipe is fixedly installed on the air pump inlet end. A filter plate is snapped onto the inner wall of the air inlet pipe. The air pump outlet end is fixedly installed on one end of a bend. A conical nozzle is fixedly installed on the other end of the bend. An adjustment valve is provided on the outer wall of the conical nozzle.

[0015] In a further embodiment, the filter plates are provided in two sets, resulting in better filtration performance.

[0016] In a further embodiment, the conical nozzle is oriented directly opposite the bottom of the drill bit.

[0017] Compared with the prior art, this utility model provides a rapid positioning and drilling device for multilayer circuit board production, which has the following advantages:

[0018] 1. This rapid positioning and drilling device for multi-layer circuit board production, in order to achieve multi-angle adjustment of the drill bit and meet the drilling requirements of different positions on the circuit board, is equipped with a rotating mechanism. When the hydraulic rod is activated, the piston end of the hydraulic rod extends and retracts, driving the U-shaped frame to rotate, thereby causing the tray to rotate. At the same time, the protrusion slides hingedly on the support plate, forming a stable triangular support structure. The rotation of the tray drives the drill bit to adjust its angle, thus completing multi-angle drilling without re-clamping the workpiece, thereby achieving multi-angle adjustment of the drill bit to meet the drilling requirements of different positions on the circuit board.

[0019] 2. This rapid positioning and drilling device for multilayer circuit board production efficiently cleans up debris generated during drilling. It is equipped with an auxiliary mechanism. An air pump draws in air through an air inlet pipe, and a double-layer filter plate filters impurities, thereby effectively preventing debris from entering the air path. Furthermore, with the help of a curved pipe and a conical nozzle, high-speed airflow is sprayed through the nozzle to the drilling position, thereby achieving efficient cleaning of debris generated during drilling.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A rapid positioning and drilling device for multilayer circuit board production includes a frame 1, a platform 11 fixedly installed at the top of the frame 1, and a moving component 2 provided on the frame 1, the moving component 2 including a support plate 3.

[0033] In one embodiment of this utility model, a rotating mechanism 4 is provided on the support plate 3. The rotating mechanism 4 includes a first hinge block 41. The first hinge block 41 is fixedly installed on the top of the support plate 3. The first hinge block 41 is internally hinged to the fixed end of the hydraulic rod 42. The piston end of the hydraulic rod 42 is hinged to a second hinge block 43. Two sets of hydraulic rods 42 are provided. The outer wall of the second hinge block 43 is fixedly installed on one side of the U-shaped frame 44. The other side of the U-shaped frame 44 is fixedly installed on the outer wall of the support plate 45. One end of the protrusion 46 is fixedly installed on the bottom outer wall of the support plate 45. 6. The other end is hinged to the side wall of the support plate 3. An asynchronous motor 47 is fixedly installed at the bottom of the support plate 45. A rotating drum 48 is fixedly installed at the output end of the asynchronous motor 47. The outer wall of the rotating drum 48 is rotatably installed inside the support plate 45 through a bearing. A drill bit 49 is slidably fitted inside the rotating drum 48. The top of the drill bit 49 is rectangular. A limiting groove 410 is opened at the top of the drill bit 49. A limiting block 411 is threaded inside the outer wall of the rotating drum 48. The outer wall of the limiting block 411 is slidably fitted inside the limiting groove 410. The limiting groove 410 and the limiting block 411 are matched in size.

[0034] In this embodiment, when in use, the hydraulic rod 42 is activated. The hydraulic rod 42 provides driving force through the extension and retraction of the piston end. The fixed end of the hydraulic rod 42 is hinged to the support plate 3 through the first hinge block 41, forming a stable fulcrum. The extension and retraction of the piston end drives the second hinge block 43 to move linearly, converting hydraulic energy into mechanical energy. The second hinge block 43 is fixedly connected to the U-shaped frame 44, causing the U-shaped frame 44 to rotate around the fulcrum. The rotation of the U-shaped frame 44 drives the fixed support plate 45 to rotate synchronously. The asynchronous motor 47, the rotating drum 48, and the drill bit 49 on the support plate 45 change their angles accordingly. The protrusion 46 at the bottom of the support plate 45 slides hingedly on the side wall of the support plate 3, forming a triangular stable structure with the hydraulic rod 42 and the support plate 45, ensuring force balance during adjustment. By controlling the difference in extension and retraction of the two sets of hydraulic rods 42, the drill bit 49 can be adjusted at multiple angles within the range. After the asynchronous motor 47 is powered on, it drives the rotating drum 48 to rotate at high speed. The limiting block 411 on the inner wall of the rotating drum 48 cooperates with the rectangular limiting groove 410 on the top of the drill bit 49, which not only transmits torque but also allows the drill bit 49 to slide axially. When it is necessary to replace the drill bit 49, the limiting block 411 is rotated counterclockwise to disengage from the limiting groove 410. Without the limiting block 411 restricting the drill bit 49, the drill bit 49 can be easily removed. The required drill bit 49 is placed in place, and the limiting block 411 is rotated clockwise to enter the limiting groove 410, thereby fixing the drill bit 49 and realizing the replacement of the drill bit 49.

[0035] In one embodiment of this utility model, an auxiliary mechanism 5 is provided on the support plate 3. The auxiliary mechanism 5 includes an air pump 51. The air pump 51 is fixedly installed on the side wall of the support plate 3. An air inlet pipe 52 is fixedly installed at the air inlet end of the air pump 51. A filter plate 53 is snapped onto the inner wall of the air inlet pipe 52. Two sets of filter plates 53 are provided. The air outlet end of the air pump 51 is fixedly installed at one end of a bend pipe 54. A conical nozzle 55 is fixedly installed at the other end of the bend pipe 54. An adjusting valve 56 is provided on the outer wall of the conical nozzle 55. The conical nozzle 55 faces the bottom end of the drill bit 49.

[0036] In this embodiment, the air pump 51 is started, and air is drawn in through the air inlet pipe 52. The double-layer filter plate 53 intercepts debris and dust in the air. The filtered clean air is delivered to the conical nozzle 55 through the bend pipe 54. The conical nozzle 55 is aligned with the drilling position and accelerates the airflow to form a high-speed air knife, which effectively blows away debris. By controlling the regulating valve 56, the airflow pressure can be automatically adjusted according to the drilling diameter to achieve fine control. A dust collection mechanism is provided in the storage area. The dust collection mechanism adopts existing technology and will not be described in detail here.

[0037] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional known device that can control the asynchronous motor 47 and the air pump 51. All standard parts used in this application can be purchased from the market, and the machinery, parts and equipment adopt conventional models in the prior art, which will not be described in detail here.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
