Description

Technical Field

[0001] This invention relates to the technical field of circuit board processing, and in particular to a beveling device for processing gold finger boards, and a processing method using the beveling device. Background Technology

[0002] The core function of beveling the gold finger board (i.e., gold finger beveling processing) is to create a smooth guide bevel, allowing the circuit board to be smoothly inserted into the connector slot and preventing damage to the slot contacts or gold finger plating due to jamming at right-angled edges. Simultaneously, precisely controlled bevel depth ensures complete contact of the gold fingers after board insertion, preventing issues such as plating peeling, substrate cracking, or fiberglass burrs. Therefore, beveling directly determines the assembly reliability, electrical contact stability, and product compliance of the gold finger board, making it an indispensable core process in gold finger board manufacturing.

[0003] In existing beveling technology for gold finger boards, on the one hand, traditional beveling cutters cut perpendicularly to the edge to be beveling, and the cutting force acts perpendicularly on the edge to be beveling of the gold finger board, causing stress concentration at the interface between glass fiber and resin, resulting in edge bursting defects. Moreover, existing tapered end mills (such as 90° and 120° cone angles) only change the geometry of the cutting edge, but are still actually cutting perpendicularly, without optimizing the direction of the cutting force. On the other hand, during the beveling process using beveling equipment, the cutting is unstable due to spindle polarization and tool wobble. This causes the remaining cutting edges to perform secondary cutting on the edge to be beveling of the gold finger board when the tool is cutting perpendicularly, resulting in tearing of the glass fiber in the gold finger board and affecting the molding quality of the gold finger board. Summary of the Invention

[0004] The present invention aims to at least solve one of the aforementioned technical problems existing in the prior art. Therefore, the purpose of the present invention is to provide a beveling device for processing gold finger plates, which effectively overcomes the stress concentration and edge bursting defects at the glass fiber-resin interface caused by traditional vertical cutting, while avoiding the problems of double-edged secondary cutting and glass fiber tearing caused by tool polarization or tool wobbling, extending the tool's service life, and ensuring the forming quality, assembly reliability, and electrical contact stability of the gold finger plate.

[0005] The present invention also provides a processing method using the above-mentioned beveling equipment for processing gold finger plates.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A beveling device for processing gold finger plates, comprising: Equipment body; A first support plate is connected to the main body of the equipment. The first support plate is provided with a first mounting position and a second mounting position. The first mounting position and the second mounting position are arranged opposite to each other on the first support plate along a first direction. An adjustment assembly, comprising a first adjustment member and a second adjustment member, wherein the first adjustment member and the second adjustment member are respectively connected to the first mounting position and the second mounting position; A clamping structure for securing the cutting tool is connected to the first adjusting member; The first adjusting member is used to adjust the clamping structure to rotate at a first angle around the first adjusting member; the second adjusting member abuts against the clamping structure and adjusts the clamping structure to rotate at a second angle around the first adjusting member, so as to adjust the single cutting edge of the tool to abut against the gold finger plate.

[0007] The beneficial effects of the beveling device for gold finger plate processing provided by the present invention are at least as follows: This application, by setting a first adjusting member and a second adjusting member on the first support plate, and adjusting the first angle and the second angle of the clamping structure in different directions respectively, allows the single cutting edge of the tool to abut against the gold finger plate for chamfering. The chamfering tool rotates and drives different cutting edges to sequentially become the cutting edge abutting against the gold finger plate for cutting, increasing the transverse cutting force of the cutting edge and reducing the longitudinal component of the cutting edge. This effectively overcomes the stress concentration and edge bursting defects at the glass fiber and resin interface caused by traditional vertical cutting. At the same time, it avoids the problem of secondary cutting by other cutting edges and glass fiber tearing caused by tool polarization or tool wobble, extending the tool's service life and ensuring the molding quality, assembly reliability, and electrical contact stability of the gold finger plate.

[0008] As described above, a beveling device for processing gold finger plates further includes a first connecting member, and the clamping structure is connected to the first connecting member; the first adjusting member is a drive motor, and the output shaft of the drive motor is provided with a first connecting frame, and the first connecting member is rotatably connected to the first connecting frame.

[0009] As described above, in a beveling device for processing gold finger plates, the second adjusting member includes a second adjusting member body and an adjusting rod. The second adjusting member body is embedded in the second mounting position. The adjusting rod is movably connected to the second adjusting member body and can abut against the side of the clamping structure facing the first support plate.

[0010] As described above, a beveling device for processing gold finger plates includes a clamping structure comprising a first clamping member and a second clamping member. The first clamping member is connected to a first connecting member, and the second clamping member is connected to the first clamping member to form a first mounting cavity. The cutting tool is connected within the first mounting cavity and is connected to the main body of the device.

[0011] As described above, a chamfering device for processing gold finger plates includes a first spindle, a chamfering cutter, and a spindle core. The first spindle passes through the first mounting cavity and is connected to the main body of the device. The chamfering cutter is movably connected to the spindle core, and the spindle core is movably connected inside the first spindle.

[0012] As described above, in a beveling device for processing gold finger plates, a third adjusting member is provided inside the first spindle, and the shaft core is connected to the third adjusting member.

[0013] As described above, in a beveling device for processing gold finger plates, the beveling cutter is a symmetrical multi-blade beveling cutter, and the number of cutting edges of the beveling cutter is 4, 6, 8 or more even-numbered blades; in a static state, only one cutting edge of the beveling cutter abuts against the beveling portion of the gold finger plate, and there are gaps between the remaining cutting edges and the beveling portion.

[0014] As described above, a beveling device for processing gold finger plates further includes a sensor group comprising an autocollimator and a position-sensitive detector. The autocollimator is used to emit parallel light, and the position-sensitive detector is used to receive reflected light.

[0015] As described above, a beveling device for processing gold finger plates includes a first transmission structure and a drive motor. The first support plate is rotatably connected to the first transmission structure, and the cutting tool is rotatably connected to the drive motor.

[0016] The present invention provides a processing method that uses the beveling equipment for processing gold finger plates as described above, and includes the following steps: Machining of the first support plate: On the first support plate, first mounting positions and second mounting positions for mounting the first adjusting member and the second adjusting member are respectively machined; Adjustment component installation: Install the first adjustment component and the second adjustment component in the first mounting position and the second mounting position respectively; Clamping structure installation: Connect the clamping structure to the first adjusting member, and adjust the distance S1 between the top end of the second adjusting member and the top end of the first adjusting member along the second direction; Tool installation: Connect the tool to the clamping structure and tighten it; Installation of the first support plate: Rotate the first support plate to the main body of the equipment, and electrically connect the first adjusting member, the second adjusting member and the cutting tool to the main body of the equipment respectively; Adjust the position of the cutting tool: Adjust the cutting tool so that it abuts against the starting end of the unprocessed gold finger plate at the edge to be chamfered; Adjusting the position of the clamping structure: The clamping structure is rotated at a first angle around the first adjusting member by the first adjusting member, and the clamping structure is rotated at a second angle around the first adjusting member by the second adjusting member, so that the single cutting edge of the tool abuts against the gold finger plate. Position calibration: The sensor group confirms whether the position of the cutting tool is at the preset position. If yes, the beveling device is started to process the gold finger plate; if no, the beveling device alarms and readjusts the position of the cutting tool to the preset position, and then the beveling device is started to process the gold finger plate again.

[0017] The beneficial effects of the processing method provided by this invention are at least as follows: This application, by setting a first adjusting member and a second adjusting member on the first support plate, and adjusting the first angle and the second angle of the clamping structure in different directions respectively, allows a single cutting edge of the tool to abut against the edge to be beveled on the gold finger plate for processing. The beveling tool rotates, causing different cutting edges to sequentially become the cutting edge abutting against the gold finger plate, increasing the transverse cutting force of the cutting edge and reducing the longitudinal component force. This effectively overcomes the stress concentration and edge bursting defects at the glass fiber-resin interface caused by traditional vertical cutting. It also avoids secondary cutting by other cutting edges and glass fiber tearing caused by the polarization of the first spindle or tool wobbling, extending the tool's service life. Furthermore, this application, by combining a sensor group for real-time calibration of the tool position and an alarm feedback mechanism, ensures that the tool is always in the preset processing position, significantly improving the stability and consistency of bevel processing, thereby guaranteeing the molding quality, assembly reliability, and electrical contact stability of the gold finger plate.

[0025] Example 1: An embodiment of the present invention provides a beveling device for processing gold finger plates, comprising: The device comprises a main body, a first support plate 100, an adjustment assembly, and a clamping structure 300. The first support plate 100 is connected to the main body and has a first mounting position 110 and a second mounting position 120. The first mounting position 110 and the second mounting position 120 are arranged opposite to each other on the first support plate 100 along a first direction. The adjustment assembly includes a first adjustment member 210 and a second adjustment member 220, which are respectively connected to the first mounting position 110 and the second mounting position 120. The clamping structure 300 is used to fasten the cutting tool 500 and is connected to the first adjustment member 210. The first adjustment member 210 is used to adjust the clamping structure 300 to rotate around the first adjustment member 210 by a first angle. The second adjustment member 220 abuts against the clamping structure 300 and adjusts the clamping structure 300 to rotate around the first adjustment member 210 by a second angle, so as to adjust the single cutting edge of the cutting tool 500 to abut against the gold finger plate 600.

[0026] Specifically, the angle value of the second angle is denoted as θ.

[0027] Specifically, the main body of the equipment is equipped with a computer numerical control platform for sending instructions and processing information. The first adjusting component 210, the second adjusting component 220 and the cutting tool 500 are electrically connected to the computer numerical control platform so as to control the first adjusting component 210, the second adjusting component 220 and the cutting tool 500 in a unified manner through the computer numerical control platform.

[0028] Specifically, along the second direction, the second angle is the angle between the side of the first support plate 100 facing the clamping structure 300 and the side of the clamping structure 300 facing the first support plate 100. By adjusting the size of the second angle, the single cutting edge of the tool 500 is adjusted to abut against the gold finger plate 600. This allows the chamfering tool 520 to rotate and drive different cutting edges to sequentially become the cutting edge abutting against the gold finger plate 600 for cutting. This increases the transverse cutting force of the cutting edge and weakens the longitudinal component force of the cutting edge, effectively overcoming the stress concentration and edge bursting defects at the glass fiber and resin interface caused by traditional vertical cutting. At the same time, it avoids the problem of secondary cutting by other cutting edges and glass fiber tearing caused by tool polarization or tool 500 wobbling. This extends the service life of the tool 500 and ensures the molding quality, assembly reliability, and electrical contact stability of the gold finger plate 600.

[0029] It should be noted that the first direction mentioned above is the X direction in the attached figure, and the second direction mentioned above is the Y direction in the attached figure. Specifically, the first direction and the second direction are perpendicular to each other. As an example, the first direction is parallel to the length direction of the first support plate 100, and the second direction is parallel to the thickness direction of the first support plate 100.

[0030] Furthermore, such as Figures 1-3 As shown, the chamfering device also includes a first connector 400, and a clamping structure 300 is connected to the first connector 400; the first adjusting member 210 is a drive motor, and a first connecting frame 211 is provided on the output shaft of the drive motor, and the first connector 400 is rotatably connected to the first connecting frame 211.

[0031] Specifically, the first adjusting member 210 is designed as a drive motor, which drives the clamping structure 300 to rotate around the output shaft, that is, the side of the first support plate 100 facing the clamping structure 300 rotates, thereby adjusting the first angle; the first connecting member 400 is a rolling member and is rotatably connected to the first connecting frame 211 on the output shaft of the drive motor. By providing a rotating shaft on the first connecting frame 211, and then rotatably connecting the first connecting member 400 to the rotating shaft, the clamping structure 300 can adjust the second angle along the second direction by rotating the first connecting member 400 around the rotating shaft.

[0032] Preferably, the first connector 400 is a rotating sleeve to improve the ease of installation and disassembly of the clamping structure 300.

[0033] Furthermore, such as Figures 1-3As shown, the second adjusting member 220 includes a second adjusting member body 221 and an adjusting rod 222. The second adjusting member body 221 is embedded in the second mounting position 120. The adjusting rod 222 is movably connected in the second adjusting member body 221 and can abut against the side of the clamping structure 300 facing the first support plate 100.

[0034] Specifically, along the second direction, the first mounting position 110 and the second mounting position 120 pass through both sides of the first support plate 100, so that the drive motor and the second adjusting member 220 can be embedded and mounted on the first support plate 100, and can be fastened to the first support plate 100 by means of threaded connection, so as to improve the stability of the connection between the drive motor and the second adjusting member 220.

[0035] Specifically, the second adjusting member 220 is a fluid transmission cylinder or an electric push rod; when the second adjusting member 220 is a fluid transmission cylinder, it is either a hydraulic cylinder or a pneumatic cylinder, the second adjusting member body 221 is the transmission cylinder body, the adjusting rod 222 is a telescopic rod, the second adjusting member body 221 is embedded in the second mounting position 120, the adjusting rod 222 is movably connected in the second adjusting member body 221 and can abut against the side of the clamping structure 300 facing the first support plate 100; at the same time, through the embedded structural design, after the hydraulic cylinder or pneumatic cylinder is reset, the telescopic rod can be retracted into the second mounting position 120, avoiding the telescopic rod interfering with the rotation of the clamping structure 300.

[0036] When the second adjusting member 220 is an electric push rod, the body 221 of the second adjusting member is a drive motor, and the adjusting rod 222 is a push rod structure. The push rod structure is rotatably connected to the drive motor through a lead screw, so that the drive motor controls the push rod structure to extend and abut against the side of the clamping structure 300 facing the first support plate 100. At the same time, through the embedded structural design, after the electric push rod is reset, the push rod structure can be retracted into the second mounting position 120, avoiding interference of the push rod structure with the rotation of the clamping structure 300. In this embodiment of the invention, a cylinder is preferred to improve the convenience of installation.

[0037] Furthermore, such as Figures 1-3 , Figure 6 As shown, the clamping structure 300 includes a first clamping member 310 and a second clamping member 320. The first clamping member 310 is connected to the first connecting member 400, and the second clamping member 320 is connected to the first clamping member 310 to form a first mounting cavity 330. The cutting tool 500 is connected in the first mounting cavity 330 and connected to the main body of the equipment.

[0038] Specifically, the first clamping member 310 has a mounting groove on the side facing the first support plate 100, and a buckling device is provided in the mounting groove. By snapping the first clamping member 310 onto the first connecting member 400, the buckling device can automatically lock onto the first connecting member 400, thereby securing the first clamping member 310 onto the first connecting member 400 and improving the reliability of the connection.

[0039] Specifically, the first clamping member 310 and the second clamping member 320 are respectively provided with a first mounting groove and a second mounting groove on their contact surfaces. When the first clamping member 310 and the second clamping member 320 are locked together by the first threaded fastener, the first mounting groove and the second mounting groove form a first mounting cavity 330 to clamp the tool 500 and improve the convenience of installing the tool 500.

[0040] Specifically, the rotating sleeve is also provided with a torsion spring; one end of the torsion spring is fixedly connected to the rotating sleeve, and the other end is fixedly connected to the first connecting frame 211, so as to ensure that when the clamping structure 300 is in the unadjusted state, the side of the clamping structure 300 facing the first support plate 100 is parallel to the side of the first support plate 100 facing the clamping structure 300; at the same time, through the elastic action of the torsion spring, the clamping structure 300 can automatically reset after use.

[0041] Furthermore, such as Figures 1-3 , Figure 6 As shown, the tool 500 includes a first spindle 510, a chamfering cutter 520, and a spindle core 530. The first spindle 510 passes through the first mounting cavity 330 and is connected to the main body of the equipment. The chamfering cutter 520 is movably connected to the spindle core 530, and the spindle core 530 is movably connected inside the first spindle 510. By adopting a detachable structural design, the applicability of the tool 500 to different gold finger plates 600 is effectively improved.

[0042] Furthermore, such as Figures 1-3 , Figure 6 As shown, the first spindle 510 is provided with a third adjusting component, and the spindle core 530 is connected to the third adjusting component.

[0043] Specifically, the third adjusting component is a cylinder, with the shaft core 530 connected to the telescopic rod of the cylinder. The cylinder is connected to external compressed air through a solenoid valve, which is electrically connected to a computer numerical control platform. This allows the computer numerical control platform to electrically control the extension or retraction length of the chamfering tool 520, thereby improving the intelligent control capability of the tool 500.

[0044] Specifically, along the length of the first spindle 510, the first spindle 510 is also provided with a chamfer depth scale, which facilitates manual calibration of the chamfer depth by aligning it with one of the openings of the first mounting cavity 330, thereby improving the ease of operation.

[0045] Specifically, the cutting tool 500 automatically calibrates its extension or retraction length through an automatic compensation program to provide different process parameters for gold finger plates 600 of different sheet types, thereby controlling the chamfering depth. For different grades or resin system sheets, given the processing life of the chamfering tool 520 (e.g., the total cutting path of the chamfering tool 520 is 70m), the dimensions of the first and last pieces of the gold finger plates 600 processed by the chamfering tool 520 are measured. The dimensional difference caused by the wear of the chamfering tool 520 under this lifespan is calculated. The required automatic compensation parameter W is then calculated. The dimensional difference between the first and last pieces is then reconfirmed using the automatic compensation parameter. By comparing the actual processing effect, a reasonable automatic compensation parameter W (i.e., the length by which the third adjustment component needs to extend the chamfering tool 520) is given. Finally, through the computer numerical control platform, after the predetermined automatic compensation parameter W is given, the computer numerical control platform will automatically adjust the required length of the chamfering tool 520 through the automatic compensation program as the processing life decreases, thereby achieving the function of controlling the chamfering depth through the automatic compensation program.

[0046] The automatic compensation parameter W is calculated as follows:

[0047] Furthermore, such as Figures 1-3 , Figures 8-9 As shown, the chamfering cutter 520 is a symmetrical multi-blade chamfering cutter, and the number of cutting edges of the chamfering cutter 520 is 4, 6, 8 or more even-numbered blades; in a static state, only one cutting edge of the chamfering cutter 520 abuts against the edge to be chamfered on the gold finger plate 600, and there are gaps between the other cutting edges and the edge to be chamfered.

[0048] Specifically, this application uses a single cutting edge to abut against the edge to be chamfered on the gold finger plate 600, while the other cutting edges have gaps with the edge to be chamfered. This effectively avoids secondary cutting of the edge to be chamfered by the chamfering cutter 520, eliminates the edge bursting phenomenon of the gold finger plate 600, and improves the finished product quality of the gold finger plate 600. At the same time, the chamfering cutter 520 is rotated by the first spindle 510, so that different cutting edges successively become the cutting edges that abut against the edge to be chamfered, thereby effectively extending the service life of the chamfering cutter 520.

[0049] Specifically, the cutting in this embodiment of the invention is based on the following principle: Driven by the first spindle 510, the chamfering cutter 520 rotates. A force analysis of the cutting force generated by the cutting edge of the chamfering cutter 520 reveals that F is the cutting force, F1 is the longitudinal component, and F2 is the transverse component. Based on the edge-bursting mechanism analysis, F2 affects the cutting and pushing effect of the chamfering cutter 520, acting as the cutting pushing force. F1, on the other hand, exerts a pulling effect on the glass fiber of the gold finger plate 600's chamfered portion along the length of the first spindle 510, acting as the longitudinal pulling force. Therefore, changing the contact angle between the chamfering cutter 520 and the chamfered portion of the gold finger plate 600 not only eliminates the damage caused by other cutting edges to the unstable interface but also makes the single cutting edge more stable when cutting the chamfered portion of the gold finger plate 600. This effectively reduces the longitudinal component F1 and increases the longitudinal component F2, ensuring that the chamfered portion of the gold finger plate 600 meets the required appearance after processing. It also further extends the lifespan of the chamfering cutter 520 and reduces production costs.

[0050] Furthermore, such as Figures 1-2 , Figures 4-5 As shown, the beveling device also includes a sensor group, which includes an autocollimator 710 and a position-sensitive detector (PSD). The autocollimator 710 is used to emit parallel light, and the position-sensitive detector (PSD) is used to receive reflected light.

[0051] Specifically, the autocollimator 710 is connected to the first support plate 100. The autocollimator 710 can be a photoelectric autocollimator or a laser goniometer, preferably a laser goniometer for emitting parallel light. When the clamping structure 300 is in the initial position, the parallel light emitted by the laser goniometer is parallel to the surface of the first support plate 100. When the second angle along the second direction changes, the parallel light emitted by the laser goniometer changes synchronously. The position of the laser reflection is captured by the position sensitive detector (PSD), thereby calculating the actual change angle of the tool 500. The actual change angle is calibrated and confirmed with the angle set by the computer numerical control platform to determine whether the position of the tool 500 is the preset position. If yes, the chamfering equipment is started to process the gold finger plate 600. If no, the chamfering equipment alarms and readjusts the position of the tool 500 to the preset position, and then the chamfering equipment is started to process the gold finger plate 600.

[0052] like Figures 1-2As shown, the main body of the equipment includes a first transmission structure 810 and a drive motor. A first support plate 100 is rotatably connected to the first transmission structure 810, and a cutter 500 is rotatably connected to the drive motor. Through the adjustable structure design of the cutter 500, the stress concentration and edge bursting defects at the interface between glass fiber and resin caused by traditional vertical cutting are effectively overcome. At the same time, the secondary cutting of other cutting edges and glass fiber tearing caused by the polarization of the first spindle 510 or the wobbling of the cutter 500 are avoided. This extends the service life of the cutter 500 and improves the stability and consistency of bevel processing, thereby ensuring the molding quality, assembly reliability and electrical contact stability of the gold finger plate 600.

[0053] Specifically, the first transmission structure 810 is a screw, which is driven by a motor to rotate, so that the tool 500 can accurately cut the chamfer of the gold finger plate 600.

[0054] like Figures 1-9 As shown, an embodiment of the present invention provides a processing method comprising the following steps: S1. Machining of the first support plate: On the first support plate 100, first mounting position 110 and second mounting position 120 for mounting the first adjusting member 210 and the second adjusting member 220 are respectively machined.

[0055] S2. Adjustment component installation: Install the first adjustment component 210 and the second adjustment component 220 in the first mounting position 110 and the second mounting position 120 respectively, and fasten the first adjustment component 210 and the second adjustment component 220 to the first support plate 100 using the first threaded connector and the second threaded connector respectively.

[0056] S3. Clamping structure installation: Connect the clamping structure 300 to the first adjusting member 210, and adjust the distance S1 between the top end of the second adjusting member 220 and the top end of the first adjusting member 210 along the second direction.

[0057] Specifically, the distance S1 between the top of the second adjusting member 220 and the top of the first adjusting member 210 is the distance along the second direction between the end of the adjusting rod 222 and the connecting end of the first connecting member 400 toward the first clamping member 310. The first clamping member 310 is connected to the first connecting member 400 through a mounting slot. Then, the adjusting rod 222 of the second adjusting member 220 is adjusted so that the adjusting rod 222 is completely retracted into the second mounting position 120. At this time, the distance S1 is at its maximum value, which can effectively prevent the adjusting rod 222 from interfering with the first adjusting member 210 driving the clamping structure 300 to rotate, thereby improving the safety of the chamfering equipment adjustment.

[0058] S4. Tool installation: Connect the tool 500 into the clamping structure 300 and tighten it.

[0059] Specifically, the first spindle 510 is installed in the first mounting cavity 330, and the first clamping member 310 and the second clamping member 320 are locked by using a third fastener to fasten the tool 500 in the clamping structure 300, so that the tool 500 can be oscillated and adjusted by the clamping structure 300.

[0060] S5. Installation of the first support plate: Rotate the first support plate 100 to the chamfering equipment, and electrically connect the first adjusting member 210, the second adjusting member 220 and the cutter 500 to the chamfering equipment respectively.

[0061] Specifically, the first support plate 100 is rotatably connected to the first transmission structure 810, and then the first adjusting member 210, the second adjusting member 220 and the third adjusting member of the tool 500 are electrically connected to the computer numerical control platform so as to control the first adjusting member 210, the second adjusting member 220 and the third adjusting member in a unified manner through the computer numerical control platform.

[0062] S6. Adjust the position of the cutting tool: Adjust the cutting tool 500 so that it abuts against the starting end of the edge to be chamfered on the gold finger plate 600.

[0063] Specifically, the third adjusting component is controlled by a computer numerical control platform, which pushes the chamfering cutter 520 to abut against the starting end of the unprocessed gold finger plate 600 to be chamfered, so as to carry out processing.

[0064] S7. Adjust the position of the clamping structure 300: Adjust the first angle of the clamping structure 300 around the first adjusting member 210 by adjusting the first adjusting member 210, and adjust the second angle of the clamping structure 300 around the first adjusting member 210 by adjusting the second adjusting member 220, so that the single cutting edge of the tool 500 abuts against the gold finger plate 600.

[0065] Specifically, the first adjusting member 210 and the second adjusting member 220 are controlled by the computer numerical control platform to adjust the first angle and the second angle respectively, so that the single cutting edge of the chamfering cutter 520 abuts against the edge to be chamfered of the gold finger plate 600, and there are gaps between the other cutting edges and the edge to be chamfered. This eliminates the damage to the unstable interface caused by the other cutting edges during the cutting process, and also makes the single cutting edge more stable when cutting the edge to be chamfered of the gold finger plate 600, improving the cutting quality of chamfering of the gold finger plate 600, and further extending the life of the chamfering cutter 520 and reducing production costs.

[0066] S8. Position calibration: Confirm whether the position of the tool 500 is the preset position through the sensor group. If yes, start the chamfering equipment to process the gold finger plate 600; if no, the chamfering equipment alarms and readjusts the position of the tool 500 to the preset position, and then starts the chamfering equipment to process the gold finger plate 600.

[0067] Specifically, after the first and second angles are adjusted, the position sensitive detector (PSD) captures the reflection position of the parallel light emitted by the laser goniometer, thereby calculating the actual change angle of the tool 500. The actual change angle is then calibrated and confirmed with the angle set by the computer numerical control platform to determine whether the position of the tool 500 is the preset position. If yes, the chamfering equipment is started to process the gold finger plate 600; otherwise, the chamfering equipment alarms and readjusts the position of the tool 500 to the preset position, and then the chamfering equipment is started to process the gold finger plate 600.

[0068] S9. Inspection: During the beveling process of the gold finger board 600, the appearance of the beveling gold finger board 600 is randomly inspected, and edge bursting defects are detected by using automatic optical inspection (AOI) to improve the finished quality of the beveling gold finger board 600.

[0069] To verify the effect of different angle values ​​θ on tool life during edge chipping, the diameter of the chamfering tool 520 was kept constant, and the tool life during edge chipping was tested by changing the angle value θ, as shown in Table 1 below: Table 1

[0070] As shown in the table above, when the angle value θ of the second angle is in the range of 0°≤θ<5°, compared with the multiple cutting edges of the chamfering tool 520 being directly perpendicular to the edge to be chamfered on the gold finger plate 600, by changing the second angle and using a single cutting edge to cut against the edge to be chamfered, the tool life of the tool 500 can be effectively extended, and production costs can be saved.

[0071] Example 2: like Figures 1-3 , Figure 7 As shown, the difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 does not use a second adjusting member 220 to adjust the second angle, but instead uses a detachable shim 230 to adjust the second angle. The detachable shim 230 can be inserted into the gap between the first support plate 100 and the clamping structure 300, thereby adjusting the size of the second angle and enabling cutting with a single cutting edge. The detachable shim 230 has a first surface 231 and a second surface 232. The first surface 231 abuts against the first support plate 100, and the second surface 232 abuts against the clamping structure 300. The first surface 231 and the second surface 232 intersect and form a first included angle β. By changing different first included angles β, detachable shims 230 of different specifications can be made. By inserting detachable shims 230 of different specifications into the gap between the first support plate 100 and the clamping structure 300, the size of the second angle can be adjusted, improving the flexibility of adjustment.

[0072] Specifically, to enhance the stability of the removable pad 230 when it is engaged, a guide groove can be provided on the side of the first clamping member 310 facing the first support plate 100. The removable pad 230 can be slidably engaged in the guide groove to prevent the removable pad 230 from deflecting during use and effectively improve the reliability of the adjustment of the removable pad 230.

[0073] Specifically, the removable gasket is made of aramid fiber to improve its abrasion resistance and deformation resistance.

[0074] Example 3: The difference between Embodiment 3 and Embodiment 1 is that Embodiment 3 does not have a second adjusting member 220, but instead has an eccentric sleeve. The eccentric sleeve is located in the first mounting cavity 330. The first spindle 510 passes through the eccentric sleeve and is rotatably connected to the main body of the equipment. By fastening the first spindle 510 to the eccentric sleeve, and by using multiple eccentric sleeves with a customized angle range of 0 to 20°, the angle between the first spindle 510 and the surface of the first support plate 100 can be adjusted, thereby enabling a single cutting edge to perform cutting.

[0075] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
