Description

Technical Field

[0001] The present application relates to the technical field of milling cutter detection, and in particular to a PCB milling cutter detection device. Background Art

[0002] A PCB milling cutter, also known as a PCB routing cutter, is an important tool used in processes such as cutting, grooving, and milling during the manufacturing of a PCB (Printed Circuit Board). During the PCB processing, precise cutting is required, so the size and shape of the PCB milling cutter need to be maintained precisely. A PCB milling cutter detection device is a dedicated device for detecting the performance, precision, and lifespan of PCB milling cutters. These devices usually feature high precision, high sensitivity, and high automation, and can ensure the precision and stability of PCB milling cutters during manufacturing and use.

[0003] The utility model patent publication number CN210570793U discloses a milling cutter detector, which includes a detection device and a fixture. The fixture includes a fixed seat, on which a mounting shaft is rotatably installed and penetrates through the fixed seat. One end of the mounting shaft is fixedly installed with a mounting plate, and a milling cutter is detachably installed on the mounting plate. A clamping device cooperating with the milling cutter is installed on the outer side wall of the mounting plate away from the fixed seat. The clamping device includes a fixing plate fixedly installed on the outer side wall of the bottom end of the mounting plate. In the present utility model, when detecting the milling cutter, one end of the milling cutter is clamped between the fixing plate and the clamping plate, and rotating the turntable can drive the mounting shaft, the mounting plate, and the milling cutter to rotate, so as to conveniently detect the milling cutter. However, the milling cutter clamped on the fixture needs to be replaced before each processing, resulting in relatively poor overall detection efficiency. Summary of the Invention

[0004] In order to solve the problem of relatively low milling cutter detection efficiency in the milling cutter detector, the present application provides a PCB milling cutter detection device.

[0005] The PCB milling cutter detection device provided by the present application adopts the following technical solution:

[0006] A PCB milling cutter detection device includes:

[0007] An installation box body, provided with a material inlet and a material outlet;

[0008] A feeding mechanism, arranged inside the installation box body, includes a first track and a feeding tray. The first track communicates the material inlet and the material outlet, and the feeding tray moves on the first track. The feeding tray can carry multiple PCB milling cutters;

[0009] A detection and marking mechanism, includes a detection arm and a marking arm. The first track moves the feeding tray past the detection arm and the marking arm in sequence. The detection arm is used to detect the PCB milling cutter, and the marking arm is used to mark the unqualified PCB milling cutters.

[0010] By adopting the above technical solution, since the volume of the PCB milling cutter is small, multiple can be carried by the feeding tray for batch detection, thereby improving the detection efficiency. However, due to batch detection, for unqualified products detected, it also takes time to distinguish them. Therefore, by providing a marking arm and marking unqualified products, after the feeding tray transports the products out of the detection device, the unqualified products can be quickly distinguished through the marks, thereby improving the processing efficiency.

[0011] Optionally, the detection and marking mechanism includes a second track, and the detection arm and the marking arm move on the second track.

[0012] By adopting the above technical solution, since the area of the feeding tray is large and the operating ranges of the detection arm and the marking arm are limited, by providing a second track, the moving ranges of the detection arm and the marking arm can be increased, so that the detection device can be applied to feeding trays with larger areas and the applicability of the detection device can be improved.

[0013] Optionally, the detection arm and the marking arm are connected and move synchronously on the second track.

[0014] By adopting the above technical solution, the detection arm needs to pass by each PCB milling cutter, while the marking arm only needs to pass by some of the milling cutters. By connecting the detection arm and the marking arm, the detection arm and the marking arm can move synchronously on the second track, so that when the detection arm passes by the position where the PCB milling cutter passes, the marking arm can also pass by when marking unqualified milling cutters. By using one moving device to move the detection arm and the marking arm, the control of the detection and marking mechanism can be simplified.

[0015] Optionally, the first track is perpendicular to the second track.

[0016] By adopting the above technical solution, the first track and the second track are perpendicular, so that during the synchronous movement of the detection arm and the marking arm on the second track, their positions relative to the feeding tray on the first track are relatively stable, and the detection arm and the marking arm do not need to move over a large range.

[0017] Optionally, the feeding mechanism further includes a lifting device. The number of the lifting devices is two, which are respectively arranged at the positions of the first track corresponding to the detection arm and the marking arm, and the lifting device is used to lift the feeding tray on the first track.

[0018] By adopting the above technical solution, placing the feeding mechanism and the detection and marking mechanism side by side will result in too large an occupied area of the detection device. Therefore, placing the feeding mechanism and the detection and marking mechanism vertically can improve the space utilization rate of the detection device. By using the lifting device to lift the feeding tray transported below the detection arm and the marking arm, it is more convenient for the detection arm and the marking arm to operate on the PCB milling cutters in the feeding tray.

[0019] Optionally, the lifting device includes a lifting frame and a retaining piece. The lifting frames are respectively arranged on both sides of the first track, and the retaining piece is connected to the lifting frame and used to limit the position of the feeding tray.

[0020] By adopting the above technical solution, when the feeding tray passes through the lifting device, the retaining piece can block the feeding tray, so that the feeding tray can be in an accurate position before lifting. Thus, the detection arm and the marking arm do not need to be greatly adjusted to complete detection and marking, improving the efficiency of milling cutter detection.

[0021] Optionally, the installation box body is provided with a glass door, and the glass door corresponds to the detection and marking mechanism.

[0022] By adopting the above technical solution, when the glass door is closed, due to its transparent property, the operator can observe the detection process. When the detection and marking mechanism needs to be adjusted or repaired, the glass door is opened, so that the operator can also access the detection and marking mechanism from the outside.

[0023] Optionally, the installation box body is provided with operation buttons and a display screen.

[0024] By adopting the above technical solution, the operation buttons enable the operator to simply control the components inside the detection device, improving the operability of the detection device. The display screen can display the operating status of the detection device. When a fault or operation error occurs, it can be displayed in a timely manner, and during the daily detection process, it can also display data such as detection results and detection process parameters, which is beneficial to the use of the detection device.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Since it is batch detection, even if unqualified products are detected, it takes time to distinguish them. Therefore, by providing a marking arm and marking unqualified products, after the feeding tray is transported out of the detection device, the unqualified products can be quickly distinguished through the marking, thus improving the processing efficiency;

[0027] 2. Since placing the feeding mechanism and the detection and marking mechanism side by side will result in too large an occupied area of the detection device, placing the feeding mechanism and the detection and marking mechanism vertically can improve the space utilization rate of the detection device. And the lifting device lifts the feeding tray transported below the detection arm and the marking arm, facilitating the operation of the PCB milling cutter in the feeding tray by the detection arm and the marking arm;

[0028] 3. When the feeding tray passes through the lifting device, the retaining piece can block the feeding tray, so that the feeding tray can be in an accurate position before lifting. Thus, the detection arm and the marking arm do not need to be greatly adjusted to complete detection and marking, improving the efficiency of milling cutter detection.

Detailed Description of the Embodiment

[0034] The following further describes the present application in detail with reference to the accompanying drawings.

[0035] A PCB milling cutter detection device, referring to Figure 1 , includes an installation box body 1, a feeding mechanism 2 and a detection and marking mechanism 3. The installation box body 1 is a cuboid structure, divided into upper and lower parts. Among them, the feeding port 11 and the discharging port 12 are arranged on both sides of the lower part of the installation box body 1 for loading and unloading PCB milling cutters. A glass door 13 is provided on the upper part of the installation box body 1. The glass door 13 not only facilitates the operator to observe the internal working conditions of the device, but also enables quick repair and adjustment of the devices inside the installation box body 1 after being opened. And operation buttons 15 are provided on the outer side of the installation box body 1, and a display screen 14 is provided inside the installation box body 1. The operation buttons 15 can simply control the components inside the installation box body 1, and the display screen 14 can intuitively display the operation status of the detection device, improving the usability and interactivity of the device.

[0036] Referring to Figure 2 , 3And 4, the feeding mechanism 2 is installed at the lower part of the installation box body 1, including a first track 21 and a feeding tray 22. The feeding tray 22 can be driven by the first track 21 to move. Multiple feeding trays 22 can be carried on the first track 21 at the same time to realize continuous detection of PCB milling cutters. The first track 21 includes a circulating conveyor belt 24 and a plurality of fixing protrusions provided on the conveyor belt 24. A set of fixing protrusions can fix one feeding tray 22, so that the feeding tray 22 can be transported by the conveyor belt 24. The lower side of the feeding tray 22 has a fixing groove 28, and the fixing groove 28 can fit with the fixing protrusion 25. By inserting the feeding tray 22 on the fixing protrusion 25, the conveyor belt 24 can be connected to the feeding tray 22, so that the conveyor belt 24 can drive the feeding tray 22 to move.

[0037] Refer to Figure 3 , the detection and marking mechanism 3 is installed at the upper part of the installation box body 1, corresponding to the glass door 13. The detection and marking mechanism 3 includes a detection arm 31, a marking arm 32 and a second track 33. The detection arm 31 and the marking arm 32 are connected to each other and move together on the second track 33. The detection arm 31 can detect whether the size of the PCB milling cutter on the feeding tray 22 is accurate, and the marking arm is used to mark the PCB milling cutters that fail the detection. By connecting the detection arm 31 and the marking arm 32 to move synchronously on the second track 33, not only can the operation range of the detection arm 31 and the marking arm 32 be expanded, but also the movement of the two components can be completed by a single driving device, making the control method of the detection and marking mechanism 3 more convenient.

[0038] Refer to Figure 2 And 3 , since the detection arm 31 and the marking arm 32 are located above the first track 21, the feeding tray 22 needs to be lifted upward to a suitable processing position. Therefore, lifting devices 23 are provided on both sides of the first track 21. The lifting devices 23 are used to lift the feeding tray 22 to the operation range of the detection and marking mechanism 3 located at the upper part of the installation box body 1, making the operation of the detection and marking mechanism 3 more convenient. The number of the lifting devices 23 is two, which are respectively arranged at the positions of the first track 21 corresponding to the detection arm 31 and the marking arm 32. The lifting device 23 is composed of a lifting frame 26 and a retaining piece 27. The lifting frame 26 is installed on both sides of the first track 21 and can move upward to lift the feeding tray 22. Since the feeding tray 22 is inserted on the fixing protrusion 25 on the conveyor belt 24 through the fixing groove 28, the connection between the fixing groove 28 and the fixing protrusion 25 can be released by lifting upward. The retaining piece 27 is connected to the lifting frame 26 and can block the feeding tray 22 from being continuously transported by the conveyor belt 24, so that the conveyor belt 24 stops rotating, and the feeding tray 22 stays at a suitable position. When the lifting frame 26 descends, the retaining piece 27 is lowered to a height that does not hinder the feeding tray 22 from moving on the conveyor belt 24, so that the feeding tray 22 can continue to move through the lifting device 23.

[0039] The implementation principle of the embodiment of this application is as follows: Before feeding, the PCB milling cutters are neatly arranged in the feeding tray 22 with the milling cutter openings facing upward. During feeding, at the feeding port 11, the feeding tray 22 is connected to the first track 21 by inserting the fixing protrusions 25 into the fixing grooves 28. The first track 21 transports the feeding tray 22 to the position corresponding to the detection arm 31, and the lifting device 23 lifts the feeding tray 22 to the operating position of the detection arm 31. If the detection arm 31 detects a non-conforming product, it records the position of the non-conforming product and transmits it to the marking arm 32. The lifting device 23 descends, enabling the feeding tray 22 to be reinserted onto the fixing protrusions 25 and continue to be pushed by the conveyor belt 24. After the feeding tray 22 is transported below the marking arm 32, the lifting device 23 lifts the feeding tray 22 again to allow the marking arm 32 to mark the non-conforming products. After marking is completed, the first track 21 transports the feeding tray 22 to the discharging port 12. After the operator removes the feeding tray 22, the non-conforming products can be identified through the marks. This makes the detection process of PCB milling cutters faster and improves the detection efficiency.

[0040] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Identical components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
