Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a tool changing mechanism of an X-RAY transmission drilling device. Background Art

[0002] A PCB, whose full English name is Printed Circuit Board, is called a printed circuit board in Chinese, also known as a printed wiring board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Since it is made by electronic printing technology, it is called a printed circuit board. Before the appearance of printed circuit boards, the interconnection between electronic components relied on direct connection of wires to form a complete circuit. Now, although the manufacturing technology of PCBs has developed for nearly 100 years, the manufacturing quality and efficiency of PCBs still seriously rely on manufacturing equipment and on-site management. Especially for high-density multi-layer PCB boards, the processing difficulty is great. In about 60 manufacturing processes, defective products may occur in each process, so the yield is generally not high. Among them, the production cost of the drilling process accounts for more than 30% of all processes.

[0003] In the drilling process, the outer diameter of the drill bit for PCB drilling may become smaller due to wear, and if it is not replaced in time, it will cause the aperture of a batch of PCB processing to be too small and unqualified; because the number of holes in the PCB is very large and the aperture sizes are various due to design requirements, during the drilling process, the drill bit needs to be frequently replaced. When most drill bits are replaced, the tool changing disk is usually located outside the equipment, resulting in a long moving path of the tool changing module and extremely low efficiency during the replacement process, which cannot meet the needs of mass production. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tool changing mechanism of an X-RAY transmission drilling device in view of the deficiencies of the prior art.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A tool changing mechanism of an X-RAY transmission drilling device includes a drilling tool and a tool changing platform. The tool changing platform includes a driving plate and a tool changing disk, and the driving plate and the tool changing disk can move relative to each other in the Y-axis direction; a tool changing manipulator horizontally aligned with the tool changing disk is arranged beside the tool changing platform, a tool changing module capable of moving in the X and Z axes is installed at the driving end of the tool changing manipulator, and the drilling tool can move in the X and Y axes.

[0007] Further: The tool changing platform further includes a tool changing driving seat. The driving plate and the tool changing disk are both arranged on the tool changing driving seat, and the tool changing driving seat is provided with a tool disk driving part for driving the tool changing driving seat to move in the Y-axis direction.

[0008] Further: The tool change driving seat is laterally formed with a tool disc support plate for installing the tool change disc. The tool disc support plate is located below the driving plate. The tool disc driving member includes a laterally telescopic cylinder arranged along the Y-axis, and the driving end of the laterally telescopic cylinder is connected to the driving plate.

[0009] Further: The tool change disc is formed with a plurality of positioning grooves, and spare drill bits are placed in the positioning grooves. The sizes of one or more of the spare drill bits are different.

[0010] Further: The tool change manipulator includes a support column arranged longitudinally. The support column is installed with a first linear module arranged in the Z-axis direction. The driving end of the first linear module is installed with a second linear module arranged in the X-axis direction. The tool change module is longitudinally installed at the driving end of the second linear module.

[0011] Further: The top of the support column is installed with a Z-axis mounting plate, and the first linear module is installed on the Z-axis mounting plate.

[0012] Further: The tool change mechanism further includes a bottom support seat for installing the drilling tool. The bottom support seat is slidably installed with an X-axis moving seat along the X-axis. The X-axis moving seat is slidably installed with a Y-axis moving seat. The Y-axis moving seat is installed with an installation tool seat capable of moving longitudinally. The drilling tool is installed on the installation tool seat.

[0013] Further: The bottom support seat is provided with an X-axis guide rail along the X-axis. The X-axis guide rail is slidably installed with an X-axis sliding seat, and the X-axis moving seat is installed on the X-axis sliding seat.

[0014] Further: The X-axis moving seat is provided with a Y-axis guide rail along the Y-axis direction. The Y-axis guide rail is slidably installed with a Y-axis sliding seat, and the Y-axis moving seat is installed on the Y-axis sliding seat.

[0015] The beneficial effects of the present utility model: When tool change is required, relative movement can occur between the driving plate and the tool change disc in the Y-axis direction, so that the tool change disc can be exposed outward from the driving plate, making the tool change disc flush with the tool change module and the drilling tool in the X-axis direction respectively. The tool change manipulator replaces the drilling tool with the tool change disc through the tool change module. During replacement, the movement path of the tool change module is reduced, enabling rapid replacement, improving the replacement efficiency, and meeting the requirements of mass production.

[0029] The following describes the present utility model in detail with reference to the accompanying drawings.

[0030] As Figures 1-3 shown, a tool changing mechanism of an X - RAY transmission drilling device includes a drilling tool 34 and a tool changing platform 1. The tool changing platform 1 includes a driving board 11 and a tool changing disc 12, and the driving board 11 and the tool changing disc 12 can move relative to each other in the Y - axis direction;

[0031] A tool changing manipulator 2 is arranged beside the tool changing platform 1 and is horizontally aligned with the tool changing disc 12. The driving end of the tool changing manipulator 2 is equipped with a tool changing module 24 that can move in the X and Z axes, and the drilling tool 34 can move in the X and Y axes.

[0032] When tool changing is required, the driving board 11 and the tool changing disc 12 can move relative to each other in the Y - axis direction, so that the tool changing disc 12 can be exposed outward on the driving board 11, making the tool changing disc 12 flush with the tool changing module 24 and the drilling tool 34 in the X - axis direction. The tool changing manipulator 2 replaces the drilling tool 34 with the tool changing module 24 to the tool changing disc 12. During replacement, the movement path of the tool changing module 24 is reduced, enabling rapid replacement, improving the replacement efficiency, and meeting the requirements of mass production.

[0033] In one embodiment, the tool change platform 1 further includes a tool change driving seat 13. The driving plate 11 and the tool change disc 12 are both installed on the tool change driving seat 13. The tool change driving seat 13 is provided with a tool disc driving member that drives the tool change driving seat 13 to move in the Y-axis direction. Driven by the tool disc driving member, the driving plate 11 can move in the Y-axis direction. When the driving plate 11 moves away from the tool change disc 12, the driving plate 11 will not block the tool change disc 12 at this time, so that the tool change disc 12 can be exposed and aligned with the tool change module 24 of the tool change manipulator 2 in the X-axis direction, facilitating rapid tool change.

[0034] The tool change driving seat 13 is horizontally formed with a tool disc support plate 14 for installing the tool change disc 12. The tool disc support plate 14 is located below the driving plate 11. The tool disc driving member includes a horizontally telescopic cylinder 15 arranged along the Y-axis. The horizontally telescopic cylinder 15 is installed on the tool disc support plate 14, and the driving end of the horizontally telescopic cylinder 15 is connected to the tool change disc 12. When the horizontally telescopic cylinder 15 makes an extending movement, the tool change disc 12 can move away from the driving plate 11, so that the tool change disc 12 can move along the tool disc support plate 14 to be exposed until it is aligned with the tool change module 24 of the tool change manipulator 2 in the X-axis direction, facilitating rapid tool change.

[0035] The tool change disc 12 is formed with a plurality of positioning grooves 16. Spare drill bits 17 are placed in the positioning grooves 16. The sizes of one or more of the spare drill bits 17 are different. According to requirements, the corresponding sized spare drill bits 17 can be picked up for drilling.

[0036] The tool change manipulator 2 includes a support column 21 arranged longitudinally. The support column 21 is installed with a first linear module 22 arranged in the Z-axis direction. The driving end of the first linear module 22 is installed with a second linear module 23 arranged in the X-axis direction. The tool change module 24 is longitudinally installed at the driving end of the second linear module 23. Driven by the first linear module 22 and the second linear module 23, the tool change module 24 can move in the X-axis and Z-axis directions. The tool change module 24 moves above the tool change disc 12, is coaxially aligned with the spare drill bit 17 to be replaced, and then approaches the spare drill bit 17 and is replaced and installed in the corresponding drill bit hole.

[0037] Preferably, a Z-axis mounting plate 25 is installed at the top of the support column 21, and the first linear module 22 is installed on the Z-axis mounting plate 25 to ensure the stable installation of the first linear module 22 in the Z-axis direction.

[0038] It should be noted that the tool change module 24 adsorbs the spare drill bit 17 or the drilling tool 34 by adsorption and then replaces it on the tool change disc 12, which is common knowledge in the field of tool change. The specific structure of the tool change module 24 will not be elaborated here.

[0039] The tool changing mechanism further includes a bottom support seat 3 for mounting the drilling tool 34. The bottom support seat 3 is slidably mounted with an X-axis moving seat 31 along the X-axis. The X-axis moving seat 31 is slidably mounted with a Y-axis moving seat 32. The Y-axis moving seat 32 is mounted with a mounting tool seat 33 capable of moving longitudinally. The drilling tool 34 is mounted on the mounting tool seat 33. With the cooperation of the X-axis moving seat 31 and the Y-axis moving seat 32, the mounting tool seat 33 can move in the X and Y directions, approaching or departing from the tool changing disc 12, and can be aligned with the tool changing disc 12 and the tool changing module 24 of the tool changing manipulator 2 in the X-axis direction for the tool changing module 24 to quickly change tools.

[0040] Preferably, the bottom support seat 3 drives the X-axis moving seat 31 to move along the X-axis on the bottom support seat 3 by a linear module; the X-axis moving seat 31 drives the Y-axis moving seat 32 to move in the Y-axis direction by a linear module, and the tool changing drive seat 13 is connected to the Y-axis moving seat 32.

[0041] The bottom support seat 3 is provided with an X-axis guide rail 35 along the X-axis. The X-axis guide rail 35 is slidably mounted with an X-axis sliding seat 36. The X-axis moving seat 31 is mounted on the X-axis sliding seat 36. The X-axis moving seat 31 is provided with a Y-axis guide rail 37 along the Y-axis direction. The Y-axis guide rail 37 is slidably mounted with a Y-axis sliding seat 38. The Y-axis moving seat 32 is mounted on the Y-axis sliding seat 38.

[0042] Through the sliding cooperation of the X-axis guide rail 35 and the X-axis sliding seat 36, the moving stability of the X-axis moving seat 31 can be improved; similarly, through the sliding cooperation of the Y-axis guide rail 37 and the Y-axis sliding seat 38, the moving stability of the Y-axis moving seat 32 can be improved.

[0043] In summary, it can be seen that the present utility model has the above-mentioned excellent characteristics, enabling it to enhance the efficiency that has never existed in the prior art during use and having practicality, becoming a product with extremely high practical value.

[0044] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
