Description

Technical Field

[0001] This invention belongs to the field of circuit board processing technology and relates to a gold finger beveling machine. Background Technology

[0002] A PCB (Printed Circuit Board) is an important electronic component. It serves as the support for electronic components and provides electrical connections between them. The edges of a PCB are typically designed as output terminals (commonly known as gold fingers). PCBs have a certain thickness, and normally, the edges where the gold fingers are located are flat cut edges, which can produce some burrs. Inserting the PCB's gold fingers into slots can be difficult and involves significant resistance. To facilitate the connection of the output terminals, the gold fingers on the PCB are usually beveled.

[0003] For example, Chinese patent CN219164817U discloses a dual-axis beveling machine for PCB boards, which includes two symmetrically arranged single-axis beveling machines. The two single-axis beveling machines share the same feeding mechanism and unloading mechanism, and a transfer mechanism is set in the middle. The PCB board gripping and moving mechanism vacuum adsorbs and transfers the adjusted PCB board to the PCB board support mechanism. After the PCB board is positioned, it is moved to the PCB board pressing mechanism position through the Y-axis moving mechanism. After being detected by a CCD camera, thickness gauge, and tool setter, the corresponding structural position is finely adjusted and the first edge is completed by the precision spindle assembly. The PCB board moves in the opposite direction to the transfer mechanism, the direction is adjusted, and then it is gripped by another single-axis beveling machine to complete the second edge cutting.

[0004] The detection components of the aforementioned beveling machine, such as CCD cameras, thickness gauges, and tool setters, are located at the processing position. They perform a "detection before processing" action, meaning that processing can only begin after detection is completed. This is a sequential operation method, which results in low processing efficiency while ensuring processing accuracy. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a gold finger beveling machine that can improve processing efficiency and accuracy.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A gold finger beveling machine includes a base, a feeding device and a receiving device disposed on the base, with a detection station and a processing station arranged sequentially between the feeding device and the receiving device. The detection station is equipped with a detection device, and the processing station is equipped with a processing device. It also includes a feeding device for transferring PCB boards between the feeding device and the detection station, the detection station and the processing station, and the processing station and the receiving device.

[0008] By separating inspection and processing, the processing unit can process the gold fingers of the inspected PCB board while the inspection unit is performing the inspection. This beveling machine operates in an assembly line mode, increasing processing efficiency by nearly 100% while maintaining the same processing accuracy.

[0009] In the aforementioned gold finger beveling machine, the inspection station is further provided with a first feeding device and a first clamping device, the first clamping device being located between the first feeding device and the inspection device; the processing station is further provided with a second feeding device and a second clamping device, the second clamping device being located between the second feeding device and the processing device; the loading device, the first feeding device, the second feeding device and the receiving device are arranged sequentially along the conveying direction of the feeding device, and the feeding device is used to transfer PCB boards between the loading device and the first feeding device, the first feeding device and the second feeding device, and the second feeding device and the receiving device.

[0010] The first feeding device and the second feeding device have the same structure. The first clamping device and the second clamping device have the same structure. The conveying direction of the first feeding device and the second feeding device is perpendicular to the conveying direction of the feeding device. In order to make the beveling machine more compact, the detection device and the processing device are located at the same end of the two feeding devices.

[0011] In the aforementioned gold finger beveling machine, the processing device includes a slide seat slidably mounted on a base, a first upright plate mounted on the slide seat, a second upright plate slidably mounted on one side of the first upright plate, and two third upright plates slidably mounted on the same side of the second upright plate. The base is provided with a first power assembly for driving the slide seat to slide along the conveying direction of the feeding device. The first upright plate is provided with a second power assembly for driving the second upright plate to move up and down. The second upright plate is provided with two third power assemblies for driving the two third upright plates to move horizontally, respectively. Each of the third upright plates is provided with a beveling blade for processing the gold fingers of the circuit board. The blade tips of the two beveling blades are respectively facing the upper and lower sides of the PCB board held by the second clamping plate device and are at an angle to the PCB board. Each of the third upright plates is provided with an angle adjustment mechanism for adjusting the processing angle of the beveling blade.

[0012] In the aforementioned beveling machine, a rotating plate is rotatably mounted on the third vertical plate. The rotation centerline of the rotating plate extends along the conveying direction of the feeding device. A drive spindle is mounted on the rotating plate. The drive end of the drive spindle is connected to the beveling cutter and is used to drive the beveling cutter to rotate. The angle adjustment mechanism is used to drive the rotating plate to rotate. The angle adjustment mechanism includes a drive screw mounted on the third vertical plate and driven by a drive motor, a drive guide rail, a drive block slidably mounted on the drive guide rail, and a connecting rod. The drive screw is parallel to the drive guide rail, and the drive screw is threadedly engaged with the drive block. One end of the connecting rod is hinged to the drive block, and the other end of the connecting rod is hinged to the rotating plate.

[0013] When the drive motor is working, it drives the drive screw to rotate, which in turn drives the drive block to slide along the length of the drive guide rail. Through the action of the connecting rod, it drives the rotating plate to rotate around the center line of rotation, thereby realizing the adjustment of the machining angle of the bevel cutter.

[0014] In the aforementioned gold finger beveling machine, the third vertical plate is provided with an arc-shaped guide rail, the center of which coincides with the rotation center of the rotating plate, and the rotating plate is provided with a guide slider, which slides in cooperation with the arc-shaped guide rail.

[0015] In the aforementioned gold finger beveling machine, the drive spindle is slidably mounted on a rotating plate, and the sliding direction of the drive spindle extends along the length direction of the beveling blade. The rotating plate is provided with a fourth power assembly for driving the drive spindle to slide. The base is also provided with a tool setter and a tool storage seat arranged sequentially along the conveying direction of the feeding device. The tool storage seat is provided with a tool magazine support, and the tool magazine support has multiple mounting holes arranged sequentially along the conveying direction of the feeding device. The mounting holes are used to place the beveling blade.

[0016] The tool magazine support adopts a bilateral symmetrical design. Each mounting hole contains a limiting component for fixing the beveled tool. The limiting component includes a sleeve and an elastic plate. The sleeve is coaxially mounted in the mounting hole, and the elastic plate is coaxially mounted on the outer end of the sleeve. The elastic plate has multiple expansion joints, the extension direction of which is parallel to the axis of the sleeve. The beveled tool is coaxially inserted into the elastic plate and the sleeve, and is elastically clamped by several elastic plates. An expansion ring is coaxially fixed on the outer wall of the sleeve, and the expansion ring is interference-fitted with the mounting hole.

[0017] Before machining, the bevel tool is placed within the limiting component, leaving a set of empty spaces to receive scrap tools. After the gold fingers of the first PCB board are machined, a tool setting is performed, and the position of the bevel tool is recorded. During tool change, the angle adjustment mechanism adjusts the bevel tool to the tool change angle, the first power component pushes it to the tool change position, the fourth power component extends the drive spindle, places the scrap tool in the empty mounting hole, releases the bevel tool, and the drive spindle retracts under the action of the fourth power component, completing the scrap tool removal; the first power component pushes the drive spindle to the new tool position, the drive spindle extends, clamps the new tool, and then retracts, completing the tool change. After the tool change, the tool is set again at the tool setting device. Based on the recorded bevel tool position, it automatically adjusts to the machining state, thus ending the entire tool change process.

[0018] In the aforementioned gold finger beveling machine, the first feeding device includes a feeding support, a feeding guide rail disposed on the feeding support, a feeding slide slidably disposed on the feeding guide rail, and a feeding power component for driving the feeding slide to slide on the feeding guide rail. A platform base that can move up and down relative to the feeding slide is provided on the side of the feeding slide. The platform base is provided with a support platform, a rotating pressure head that forms a pressing action with the support platform, and a clamping power component for driving the rotating pressure head to rotate. The feeding slide is provided with a height adjustment mechanism for driving the platform base to move up and down relative to the feeding slide. The base is also provided with a tray assembly for supporting the PCB board.

[0019] The pallet assembly includes a pallet body and multiple rollers located on both sides of the pallet body. The multiple rollers are arranged at the same height and along the sliding direction of the feeding slide. The rotation centerline of the rollers extends horizontally along the sliding direction perpendicular to the feeding slide.

[0020] In the aforementioned gold finger beveling machine, the base is provided with a crossbeam extending along the conveying direction of the feeding device. There are three feeding devices that are slidably arranged on the crossbeam and are driven by different fifth power components. One feeding device is used to transfer the PCB board between the feeding device and the first feeding device, another feeding device is used to transfer the PCB board between the first feeding device and the second feeding device, and the last feeding device is used to transfer the PCB board between the second feeding device and the receiving device.

[0021] In the aforementioned gold finger beveling machine, the detection device includes a movable seat slidably mounted on a base and driven by a sixth power component, and at least one detection group mounted on the movable seat. The moving direction of the movable seat is the same as the conveying direction of the feeding device. The detection group includes a first sensor and a second sensor arranged vertically opposite each other. During detection, the first sensor faces the top of the PCB board, and the second sensor faces the bottom of the PCB board.

[0022] Taking two sets of detection groups as an example, in order to adjust the distance between the two detection groups, a guide rod is slidably passed through the movable seat. The guide rod extends along the conveying direction parallel to the feeding device. A detection support is provided at the end of the guide rod. The detection support is driven by a cylinder. Under the action of the cylinder, the detection support can move along the conveying direction of the feeding device. One set of detection groups is set on the movable seat, and the other set of detection groups is set on the detection support.

[0023] Compared with existing technologies, this gold finger beveling machine has the following advantages:

[0024] The thickness data of the PCB board is detected and recorded by the detection device. The back-end processes the data and sends it to the processing station. The processing station performs fine processing according to the processed data. During the processing, the processing angle and tool change can be automatically adjusted according to the processing parameters. The dual-station design realizes the assembly line operation, reduces waiting and handling time, shortens the production cycle, reduces the ineffective working time of the equipment, and improves the equipment utilization rate, thereby greatly improving the processing efficiency. It is particularly suitable for large-volume and standardized production scenarios. Attached Figure Description

Detailed Implementation

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figure 1 and Figure 2 The gold finger beveling machine shown includes a base 10 and a crossbeam 11 spanning above the base 10. A feeding device 20 is located below one end of the crossbeam 11, and a receiving device 30 is located below the other end. In this embodiment, the feeding device 20 and the receiving device 30 are both platforms used to store PCB boards. To facilitate the transfer of PCB boards, three feeding devices 60, each driven by a different fifth power component 61, are slidably mounted on the crossbeam 11. The fifth power component 61 includes components such as a guide rail, a linear motor, and a slider. When the linear motor operates, it drives the slider to slide along the guide rail, and the feeding device 60 is fixed to the slider. The feeding device 60 includes a negative pressure suction cup connected to a negative pressure source and a power component that can drive the negative pressure suction cup to move up and down. The power component includes, but is not limited to, cylinders and hydraulic cylinders. When the power component operates, it drives the negative pressure suction cup to move up and down, thereby picking up the PCB board.

[0037] The base 10 is positioned between the feeding device 20 and the receiving device 30, with the inspection station and the processing station being arranged sequentially. The inspection station is equipped with an inspection device 40, a first feeding device 71, and a first clamping device 81. The first clamping device 81 consists of two clamping plates arranged vertically opposite each other. The upper clamping plate can be raised and lowered. When the upper clamping plate is lowered, it can clamp the PCB board together with the lower clamping plate. It is located between the first feeding device 71 and the inspection device 40.

[0038] The processing station is equipped with a processing device 50, a second feeding device 72, and a second clamping device 82. The second clamping device 82 adopts the same structure as the first clamping device 81. The second clamping device 82 is located between the second feeding device 72 and the processing device 50, and the structure of the second feeding device 72 is the same as that of the first feeding device 71. The conveying direction of the first feeding device 71 and the second feeding device 72 is perpendicular to the conveying direction of the feeding device 60. In order to make the beveling machine more compact, the detection device 40 and the processing device 50 are located at the same end of the two feeding devices.

[0039] like Figure 1 As shown, the feeding device 20, the first feeding device 71, the second feeding device 72, and the receiving device 30 are arranged sequentially along the conveying direction of the feeding device 60. One feeding device 60 is used to transfer the PCB board between the feeding device 20 and the first feeding device 71, another feeding device 60 is used to transfer the PCB board between the first feeding device 71 and the second feeding device 72, and the last feeding device 60 is used to transfer the PCB board between the second feeding device 72 and the receiving device 30.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the processing device 50 includes a slide 501 slidably disposed on the base 10, a first upright plate 502 disposed on the slide 501, a second upright plate 503 slidably disposed on one side of the first upright plate 502, and two third upright plates 504 slidably disposed on the same side of the second upright plate 503.

[0041] like Figure 3 and Figure 4As shown, the base 10 is provided with a first power component 505 for driving the slide 501 to slide along the conveying direction of the feeding device 60. The first upright plate 502 is provided with a second power component 506 for driving the second upright plate 503 to move up and down. The second upright plate 503 is provided with two third power components 507 for driving the two third upright plates 504 to move horizontally respectively. The movement direction of the third upright plates 504 is perpendicular to the conveying direction of the feeding device 60. Each third upright plate 504 is provided with a beveled blade 5081 for processing the gold fingers of the circuit board. The blades of the two beveled blades 5081 are respectively facing the upper and lower sides of the PCB board held by the second clamping plate device 82 and there is an angle between them and the PCB board. Each third upright plate 504 is provided with an angle adjustment mechanism for adjusting the processing angle of the beveled blade 5081.

[0042] The first power assembly 505, the second power assembly 506, and the third power assembly 507 are all composed of guide rails, motors, lead screws, sliders, etc. When the motor is working, it drives the lead screw to rotate. The rotation of the lead screw drives the slider that is threaded to it to slide on the guide rail, thereby driving the first vertical plate 502 / second vertical plate 503 / third vertical plate 504 connected to it to move.

[0043] like Figure 3 , Figure 4 and Figure 5 As shown, a rotating plate 508 is rotatably mounted on the third vertical plate 504. The rotation centerline of the rotating plate 508 extends along the conveying direction of the feeding device 60. A drive spindle 5082 is mounted on the rotating plate 508. The drive end of the drive spindle 5082 is connected to the bevel cutter 5081 and is used to drive the bevel cutter 5081 to rotate.

[0044] like Figure 3 , Figure 4 and Figure 5 As shown, the angle adjustment mechanism is used to drive the rotating plate 508 to rotate. The angle adjustment mechanism includes a drive screw 5083 mounted on the third vertical plate 504 and driven by a drive motor, a drive guide rail 5084, a drive block 5085 slidably mounted on the drive guide rail 5084, and a connecting rod 5086. The drive screw 5083 is parallel to the drive guide rail 5084, and the drive screw 5083 is threadedly engaged with the drive block 5085. One end of the connecting rod 5086 is hinged to the drive block 5085, and the other end of the connecting rod 5086 is hinged to the rotating plate 508. When the drive motor is working, it drives the drive screw 5083 to rotate, thereby causing the drive block 5085 to slide along the length direction of the drive guide rail 5084. Through the action of the connecting rod 5086, the rotating plate 508 rotates around the center line of rotation, thereby realizing the adjustment of the machining angle of the bevel cutter 5081.

[0045] like Figure 3 , Figure 4 and Figure 5As shown, the third vertical plate 504 is provided with an arc-shaped guide rail 5087, the center of the arc-shaped guide rail 5087 coincides with the rotation center of the rotating plate 508, the rotating plate 508 is provided with a guide slider, and the guide slider slides in cooperation with the arc-shaped guide rail 5087.

[0046] In this embodiment, the drive spindle 5082 is slidably mounted on the rotating plate 508, and the sliding direction of the drive spindle 5082 extends along the length direction of the bevel cutter 5081. The rotating plate 508 is provided with a fourth power assembly for driving the drive spindle 5082 to slide. The fourth power assembly consists of a guide rail, a motor, a lead screw, a slider, etc. Through reasonable cooperation, the rotating plate 508 can move on the third vertical plate 504.

[0047] like Figure 2 As shown, the base 10 is also equipped with a tool setter 5091 and a tool holder 5092 arranged sequentially along the conveying direction of the feeding device 60, such as... Figure 7 As shown, the tool holder 5092 is equipped with a tool magazine support 5093. The tool magazine support 5093 has multiple mounting holes arranged sequentially along the conveying direction of the feeding device 60. The mounting holes are used to place the beveled blade 5081. The tool magazine support 5093 adopts a double-sided symmetrical design. To prevent the beveled blade 5081 from falling out of the mounting holes, each mounting hole is equipped with a limiting component for fixing the beveled blade 5081. The limiting component includes a sleeve and an elastic plate. The sleeve is coaxially disposed in the mounting hole, and the elastic plate is coaxially disposed at the outer end of the sleeve. The elastic plate has multiple deformation slots, and the extension direction of the deformation slots is parallel to the axis of the sleeve. The beveled blade 5081 is coaxially inserted into the elastic plate and the sleeve, and is elastically clamped by several elastic plates. An expansion ring is coaxially fixed on the outer wall of the sleeve, and the expansion ring is interference-fitted with the mounting hole.

[0048] Before machining, the bevel cutter 5081 is placed within the limiting component, leaving a set of empty spaces to receive scrap cutters. After the gold fingers of the first PCB board are machined, a tool setting is performed, and the position of the bevel cutter 5081 is recorded. During tool change, the angle adjustment mechanism adjusts the bevel cutter 5081 to the tool change angle, the first power component 505 pushes it to the tool change position, and the fourth power component extends the drive spindle 5082, placing the scrap cutter in the empty mounting hole. The bevel cutter 5081 is released, and the drive spindle 5082 retracts under the action of the fourth power component, completing the scrap cutter removal. The first power component 505 pushes the drive spindle 5082 to the new tool position, the drive spindle 5082 extends, clamps the new tool, and then retracts, completing the tool change. After the tool change, a second tool setting is performed at the tool setting device 5091. Based on the recorded position of the bevel cutter 5081, the device automatically adjusts to the machining state, thus ending the entire tool change process.

[0049] like Figure 6As shown, the first feeding device 71 includes a feeding support 711, a feeding guide rail 712 disposed on the feeding support 711, a feeding slide 713 slidably disposed on the feeding guide rail 712, and a feeding power component 714 for driving the feeding slide 713 to slide on the feeding guide rail 712. The feeding guide rail 712 extends horizontally along the conveying direction perpendicular to the feeding device 60. A platform base 715 that can move up and down relative to the feeding slide 713 is provided on the side of the feeding slide 713, and a support platform is provided on the platform base 715. 716, a rotating pressure head 717 that forms a pressing action with the support platform 716, and a clamping power member 718 for driving the rotating pressure head 717 to rotate. A rotating rod is rotatably provided on the platform base 715. The rotating rod is driven by the clamping power member 718 (such as a rotary cylinder). There are two rotating pressure heads 717 and they are rotatably sleeved on the rotating rod. The rotating pressure head 717 and the rotating rod are circumferentially fixed. The feeding slide 713 is provided with a height adjustment mechanism 719 for driving the platform base 715 to move up and down relative to the feeding slide 713.

[0050] The height adjustment mechanism 719 includes a guide rail, a motor, a lead screw, and a slider. When the motor is working, it drives the lead screw connected to it to rotate. When the lead screw rotates, it drives the slider that is threaded to it to move up and down. The slider then drives the platform base 715 fixed to it to move up and down.

[0051] During feeding, the support platform 716 is slightly higher than the second clamping device 82. After feeding, as the second clamping device 82 clamps the PCB board, the support platform 716 releases the PCB board and lowers to a height slightly lower than the second clamping device 82. This prevents damage to the PCB board due to the height difference between the second clamping device 82 and the support platform 716, and also better ensures processing accuracy. After processing, as the second clamping device 82 releases the PCB board, the support platform 716 moves up to the feeding height position, clamps the PCB board, and retracts.

[0052] like Figure 1 As shown, the base 10 is also provided with a tray assembly 73 for supporting the PCB board. There are two tray assemblies 73, which correspond one-to-one with the first feeding device 71 and the second feeding device 72. The tray assembly 73 includes a tray body and multiple rollers on both sides of the tray body. The multiple rollers are set at the same height and arranged along the sliding direction of the feeding slide 713. The rotation center line of the rollers extends horizontally along the sliding direction perpendicular to the feeding slide 713.

[0053] like Figure 8 and Figure 9As shown, the detection device 40 includes a movable seat 402 slidably mounted on the base 10 and driven by the sixth power component 401, and at least one detection group mounted on the movable seat 402. The moving direction of the movable seat 402 is the same as the conveying direction of the feeding device 60. The detection group includes a first sensor 4031 and a second sensor 4032 arranged opposite each other. During detection, the first sensor 4031 faces the top of the PCB board, and the second sensor 4032 faces the bottom of the PCB board.

[0054] like Figure 9 As shown, there are two detection groups in this embodiment. In order to adjust the distance between the two detection groups, a guide rod 4033 is slidably passed through the movable seat 402. The guide rod 4033 extends along the conveying direction parallel to the feeding device 60. A detection support 4034 is provided at the end of the guide rod 4033. The detection support 4034 is driven by a cylinder 4035. Under the action of the cylinder 4035, the detection support 4034 can move along the conveying direction of the feeding device 60. One detection group is set on the movable seat 402, and the other detection group is set on the detection support 4034.

[0055] The processing steps of this gold finger beveling machine are as follows:

[0056] The PCB board to be processed is placed on the loading device 20, and the feeding device 60 transfers it to the tray assembly 73 at the inspection station. The first feeding device 71 feeds the PCB board into the first clamping device 81 for clamping and fixing. At this time, the inspection device 40 starts to detect the thickness of the gold fingers of the PCB board. After the inspection is completed, the first clamping device 81 is opened, and the first feeding device 71 sends the PCB board back to the tray assembly 73. The feeding device 60 then transfers it to the tray assembly 73 at the processing station. The second feeding device 72 feeds the PCB board into the second clamping device 82 for clamping and fixing. At this time, the processing device 50 starts to perform bevel processing on the gold fingers of the PCB board. After the processing is completed, the second feeding device 72 sends it back to the tray assembly, and the feeding device 60 then transfers the processed PCB board to the receiving device 30 to collect the processed PCB board, completing the entire processing process.
