Description

Technical Field

[0001] The invention relates to the technical field of ceramic splitting cutter manufacturing, in particular to a ceramic splitting cutter R angle profiling processing line. Background Art

[0002] Ceramic choppers are used in the Cob packaging process, and according to the specific process requirements, the R angle of the ceramic chopper is also different (such as Figure 1 In the actual forming process, a profiling grinding wheel is needed to form the R angle on the ceramic splitter.

[0003] In the actual implementation of Cob packaging operations, the cross-sectional changes of the gold wire start from the R corner. If the outer fillet radius is too large, the length of the solder joint will be too small, resulting in an unreliable solder joint; if the outer fillet radius is too small, the length of the solder joint will be too large, interconnected with adjacent solder joints, and the package will fail. The quality of the R corner (i.e., the outer fillet radius) is the main factor affecting the shape of the second solder joint and the corresponding bonding strength.

[0004] As far as the current status of the industry is concerned, given that the ceramic splitter is extremely small in size and the material hardness is extremely high, there is no special profiling grinding equipment for the R angle of the ceramic splitter on the market, and no relevant patents or technical literature have been retrieved. According to the traditional profiling grinding process, the ceramic splitters need to be manually supplied to the profiling grinding equipment piece by piece, and they are locked and fixed with the help of a mechanical chuck; after the R angle is profiled, the ceramic splitters are transferred to the next process in batches, and the remaining grinding chips are removed by high-speed airflow. The entire operation process is time-consuming and labor-intensive, the workers have high labor intensity, and have relatively high requirements for their operating skills. In addition, they need to go through the grinding chip cleaning process, the process route is long, and the workshop needs to plan the profiling grinding area and the grinding removal post-processing area at the same time, which is not conducive to the realization of the purpose of optimizing the layout design of the workshop. Therefore, technical personnel are urgently needed to solve the above problems. Summary of the invention

[0005] Therefore, in view of the above existing problems and defects, the designers of the present invention collected relevant information, conducted multiple evaluations and considerations, and continued to experiment and modify after many years of R&D experience in this industry, which ultimately led to the emergence of the ceramic wedge R angle profiling processing line.

[0006] In order to solve the above technical problems, the present invention relates to a ceramic splitting cutter R angle profiling processing line, including a workpiece head frame, a profiling grinding device, a grinding chip removal device, a combined carrier, a bearing unit for a workpiece to be processed, a bearing unit for a processed workpiece, and a multi-degree-of-freedom picking manipulator. The workpiece head frame is used to clamp the ceramic splitting cutter, and has its own power to drive the ceramic splitting cutter to perform circumferential rotation around its own central axis. The combined carrier has both X-direction displacement freedom and Y-direction displacement freedom, and it serves as a common assembly basis for the profiling grinding device and the grinding chip removal device. The profiling grinding device performs X-direction or / and Y-direction displacement movement under the action of the carrying force from the combined carrier, and until it reaches the processing position, it continuously applies grinding force to the ceramic splitting cutter. After the R angle of the ceramic splitter is ground and formed, the chip removal device performs an X-direction displacement movement under the carrying force from the combined carrier until it is aligned with the ceramic splitter, and then performs a Y-direction displacement movement under the carrying force from the combined carrier, and interacts with the ceramic splitter, and the remaining chips on the ceramic splitter are removed under the holding force from the chip removal device. The multi-degree-of-freedom picking manipulator is used to transfer the ceramic splitter to be processed from the workpiece bearing unit to the workpiece head frame, or the multi-degree-of-freedom picking manipulator is used to transfer the processed ceramic splitter from the workpiece head frame to the processed workpiece bearing unit.

[0007] As a further improvement of the technical solution disclosed in the present invention, the workpiece headstock includes a first bearing seat, a first rotating shaft, a first power unit and a pneumatic elastic collet. The pneumatic elastic collet is used to elastically hold the ceramic splitting tool, and it uses the first rotating shaft as a fitting and fixing basis. The horizontal first rotating shaft is supported by the first bearing seat and laterally penetrates the first bearing seat, and it is able to perform circumferential rotation due to the rotational torque from the first power unit.

[0008] As a further improvement of the technical solution disclosed in the present invention, the first power unit includes a first rotating motor and a first belt transmission mechanism. The first rotating motor is arranged on one side of the first bearing seat, and the rotational torque generated by the first rotating motor is transmitted to the first rotating shaft via the first belt transmission mechanism.

[0009] As a further improvement of the technical solution disclosed in the present invention, the profile grinding device includes a second bearing seat, a second rotating shaft, a second power unit and a profile grinding wheel. The profile grinding wheel is used for profile grinding of a ceramic splitter and is mounted on the second rotating shaft. The horizontally placed second rotating shaft is supported by the second bearing seat and laterally penetrates the second bearing seat, and is able to perform circumferential rotation due to the rotational torque from the second power unit.

[0010] As a further improvement of the technical solution disclosed in the present invention, the second power unit includes a second rotating motor and a second belt transmission mechanism. The second rotating motor is arranged on one side of the second bearing seat, and the rotational torque generated by the second rotating motor is transmitted to the second rotating shaft via the second belt transmission mechanism.

[0011] As a further improvement of the technical solution disclosed in the present invention, the profiling grinding device further includes a grinding chip recovery unit. During the grinding and forming process of the ceramic splitting cutter, the grinding chip recovery unit utilizes the negative pressure effect to continuously recover the grinding chips.

[0012] As a further improvement of the technical solution disclosed in the present invention, the grinding chip recovery unit includes a semi-enclosed shell and an exhaust pipe. The semi-enclosed shell is used to provide a negative pressure environment for the profiling grinding wheel, and the second bearing seat is used as an installation base. The exhaust pipe is connected to the semi-enclosed shell, and the inner cavity of the semi-enclosed shell is maintained in a negative pressure environment due to continuous vacuum.

[0013] As a further improvement of the technical solution disclosed in the present invention, the combined carrier platform is composed of an X-axis sliding platform and a Y-axis sliding platform stacked together.

[0014] As a further improvement of the technical solution disclosed in the present invention, the ceramic splitting cutter R angle profiling processing line also includes a visual inspection microscope. The visual inspection microscope is used to determine whether the profiling grinding device occupies the correct processing position relative to the ceramic splitting cutter, or to determine whether the formed R angle of the ceramic splitting cutter meets the quality inspection standard, and the visual inspection microscope is arranged on one side of the profiling grinding device.

[0015] As a further improvement of the technical solution disclosed in the present invention, the workpiece bearing unit to be processed and the workpiece bearing unit to be processed are placed adjacent to each other. The workpiece bearing unit to be processed is composed of a first workpiece bearing fixture to be processed and a second workpiece bearing fixture to be processed.

[0016] As a further improvement of the technical solution disclosed in the present invention, the chip removal device includes a connecting transition seat, a bearing seat, an annular chip removal belt and a third power unit. The bearing seat is used to bear the third power unit, and it is fixedly connected to the combined carrier platform by means of the connecting transition seat. The annular chip removal belt is partially concave and deformed or partially torn due to the insertion force from the ceramic splitting knife. In this process, the remaining chip on the ceramic splitting knife can be removed under the action of the holding force. The annular chip removal belt is able to perform circumferential rotation due to the torque from the third power unit.

[0017] As a further improvement of the technical solution disclosed in the present invention, the third power unit includes a stepper motor and a plane fixed-axis gear train. The annular chip removal belt is mounted on the plane fixed-axis gear train and is kept in a tensioned state. The stepper motor bearing seat is used as a power supply source for the plane fixed-axis gear train, and the annular chip removal belt rotates a fixed angle every time its rotor moves forward.

[0018] The working principle of the R-angle profiling processing line of the ceramic splitter disclosed in the present invention is roughly as follows: first, the ceramic splitters are supplied in batches to the multi-degree-of-freedom picking manipulator by means of the workpiece carrying unit to be processed. The multi-degree-of-freedom picking manipulator picks up the ceramic splitters piece by piece and inserts them into the workpiece head frame; then, the profiling grinding device performs displacement movement under the carrying force from the combined carrier until it reaches the processing position; in the subsequent time period, the ceramic splitter is continuously subjected to the grinding force from the profiling grinding device until its R angle is formed; then, the grinding chip removal device also performs position change action under the carrying force from the combined carrier until it maintains a positive position with the ceramic splitter to perform a cleaning operation on the grinding chips remaining on the ceramic splitter; then, with the assistance of the multi-degree-of-freedom picking manipulator, the ceramic splitters in the processed state are transferred piece by piece from the workpiece head frame to the processed workpiece carrying unit.

[0019] In practical applications, the ceramic wedge R angle profiling processing line disclosed in the present invention can achieve at least the following beneficial technical effects, specifically:

[0020] 1) The multi-degree-of-freedom picking manipulator cooperates with the workpiece bearing unit to realize the automatic loading operation of the ceramic splitting knife to be processed to the workpiece headstock, and the multi-degree-of-freedom picking manipulator cooperates with the workpiece bearing unit to realize the automatic unloading operation of the ceramic splitting knife in the processed state.

DETAILED DESCRIPTION

[0036] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "left", "right", "front", "back", "up", "down", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0037] The present invention will be further described in detail below with reference to specific embodiments. Figure 2 , 3 As shown in , 4, it can be known that it is mainly composed of a workpiece headstock 1, a profiling grinding device 2, a grinding chip removal device 3, a combined carrier platform 4, a workpiece carrying unit 5, a processed workpiece carrying unit 6, a multi-degree-of-freedom picking robot 7 and a substrate 8. The workpiece headstock 1, the profiling grinding device 2, the grinding chip removal device 3, the combined carrier platform 4, the workpiece carrying unit 5 and the processed workpiece carrying unit 6 use the substrate 8 as a placement and fixing basis, and the multi-degree-of-freedom picking robot 7 is independently arranged on the periphery of the substrate 3. The workpiece headstock 1 is used to clamp the ceramic splitting knife, and has its own power to drive the ceramic splitting knife to perform circumferential rotation around its own central axis. The combined carrier platform 4 is arranged in front of the workpiece headstock 1, and it serves as a common assembly base for the profiling grinding device 2 and the grinding chip removal device 3. As shown in FIG. Fig.12As shown in , the combined carrier 4 is composed of an X-direction sliding table 41 and a Y-direction sliding table 42, and has both X-direction displacement freedom and Y-direction displacement freedom. After the ceramic splitting cutter is clamped relative to the workpiece headstock 1, the profiling grinding device 2 performs X-direction or / and Y-direction displacement movement under the action of the carrying force from the combined carrier 4, and until it reaches the processing position, it continuously applies grinding force to the ceramic splitting cutter until the R angle profiling processing is completed. After the R angle grinding of the ceramic splitting cutter is completed, the chip removal device 3 performs X-direction displacement movement under the action of the carrying force from the combined carrier 4 until it is aligned with the ceramic splitting cutter, and then, it performs Y-direction displacement movement under the action of the carrying force from the combined carrier 4, and interacts with the ceramic splitting cutter, and the remaining chips on the ceramic splitting cutter are removed under the action of the holding force from the chip removal device 3. The multi-degree-of-freedom picking robot 7 is used to transfer the ceramic splitting tool to be processed from the workpiece carrying unit 5 to the workpiece headstock 1, or the multi-degree-of-freedom picking robot 7 is used to transfer the processed ceramic splitting tool from the workpiece headstock 1 to the processed workpiece carrying unit 6.

[0038] The working principle of the ceramic splitting knife R angle profiling processing line disclosed in the present invention is as follows: first, the ceramic splitting knife is supplied in batches to the multi-degree-of-freedom picking robot 7 by means of the workpiece carrying unit 5 to be processed. The multi-degree-of-freedom picking robot 7 picks up the ceramic splitting knife piece by piece and inserts it into the workpiece head frame 1; then, the profiling grinding device 2 performs displacement movement under the carrying force from the combined carrier 4 until it reaches the processing position; in the subsequent time period, the ceramic splitting knife is continuously subjected to the grinding force from the profiling grinding device 2 until its R angle is formed; then, the grinding chip removal device 3 also performs position change action under the carrying force from the combined carrier 4 until it maintains a positive position with the ceramic splitting knife to perform a cleaning operation on the grinding chips remaining on the ceramic splitting knife; then, with the assistance of the multi-degree-of-freedom picking robot 7, the ceramic splitting knife in the processed state is transferred piece by piece from the workpiece head frame 1 to the processed workpiece carrying unit 6.

[0039] By adopting the above technical solution, after the ceramic chopper is profiled and ground, it is not necessary to change the clamping state or transfer the workstation. With the help of the chip removal device 3 matched with the profile grinding device 2, the remaining chips on the ceramic chopper can be removed immediately. In this way, on the one hand, the ceramic chopper R angle profile processing line has both R angle profile grinding function and chip removal function, and the processing route can be optimized; on the other hand, the R angle profile processing and chip removal work of the ceramic chopper are concentrated in the same workstation, thereby effectively reducing the total time required for the R angle profile processing of the ceramic chopper.

[0040] Here, it is also necessary to explain that the multi-degree-of-freedom picking robot 7 cooperates with the workpiece carrying unit 5 to realize the automatic loading operation of the ceramic splitting knife to be processed toward the workpiece headstock 1, and the multi-degree-of-freedom picking robot 7 cooperates with the workpiece carrying unit 6 to realize the automatic unloading operation of the ceramic splitting knife in the processed state. The whole process does not require the participation of workers, and the work efficiency is relatively high, which is sufficient to meet the contour grinding rhythm of the contour grinding equipment.

[0041] like Figure 5 , 6 As shown in Figures 7 and 8, the workpiece headstock 1 is mainly composed of several parts such as a first force-bearing seat 11, a first rotating shaft 12, a first power unit 13 and a pneumatic elastic collet 14. The pneumatic elastic collet 14 is used to elastically hold the ceramic splitting knife, and it uses the first rotating shaft 12 as a fitting and fixing base. The horizontal first rotating shaft 12 is supported by the first force-bearing seat 11 and laterally penetrates the first force-bearing seat 11. It is able to perform circumferential rotation due to the torque from the first power unit 13. The first power unit 13 includes a first rotating motor 131 and a first belt transmission mechanism 132. The first rotating motor 131 is arranged on one side of the first force-bearing seat 11, and the torque generated by the first rotating motor 131 is transmitted to the first rotating shaft 12 via the first belt transmission mechanism 132. In actual operation, when the ceramic splitting knife is inserted into place relative to the pneumatic elastic collet 14, the high-pressure air drives the pneumatic components in the chuck to operate, so as to realize the elastic clamping and releasing actions; then, the first rotating motor 131 is started, and the first rotating shaft 12 continuously performs circumferential rotational motion due to the action of the rotational torque, and the pneumatic elastic collet 14 and the ceramic splitting knife are synchronized therewith.

[0042] like Figure 8 , 9As shown in the figure, the profiling grinding device 2 is mainly composed of several parts such as a second bearing seat 21, a second rotating shaft 22, a second power unit 23 and a profiling grinding wheel 24. The profiling grinding wheel 24 is used for profiling grinding the R angle of the ceramic splitting cutter, and it is mounted on the second rotating shaft 22. The horizontal second rotating shaft 22 is supported by the second bearing seat 21 and laterally penetrates the second bearing seat 21. It is able to perform circumferential rotation due to the torque from the second power unit 23. The second power unit 23 includes a second rotating motor 231 and a second belt transmission mechanism 232. The second rotating motor 231 is arranged on one side of the second bearing seat 21, and the torque generated by the second rotating motor 231 is transmitted to the second rotating shaft 22 via the second belt transmission mechanism 232. During the R-angle profiling grinding operation on the ceramic chopper, the second rotary motor 231 is started, and the torque generated by the second rotary motor is transmitted to the second rotary shaft 22 via the second belt transmission mechanism 232, so that the profiling grinding wheel 24 can perform a follow-up circumferential rotational motion. At the same time, the first rotary motor 131 is started, and the first rotary shaft 12 continuously performs a circumferential rotational motion due to the torque, and the ceramic chopper is able to perform a follow-up circumferential rotational motion, and the ceramic chopper is ground in small amounts layer by layer until the R-angle profiling grinding is completed.

[0043] According to common knowledge, during the high-speed grinding process of the ceramic splitter, the surface of the ceramic splitter is ground by means of the profiling grinding wheel 24, and part of the material removed by grinding is released into the air in the form of tiny particles to form dust. These dusts are composed of ceramic particles, and their existence has an important impact on the workshop environment, worker health, production equipment and other aspects. In view of this, as a further optimization of the above technical solution, as Figure 8 , 9 As shown in , the profiling grinding device 2 is equipped with a grinding chip recovery unit 25. The grinding chip recovery unit 25 is mainly composed of a semi-enclosed shell 251 and an exhaust pipe 252. The semi-enclosed shell 251 is used to provide a negative pressure environment for the profiling grinding wheel 24, and it uses the second bearing seat 21 as an installation base. The exhaust pipe 252 is connected to the semi-enclosed shell 251 and is interconnected. In this way, during the high-speed grinding process of the ceramic splitting cutter, the inner cavity of the semi-enclosed shell 251 is continuously vacuumed and maintained in a negative pressure environment, and the generated grinding dust is gathered in the dust collection box through the exhaust pipe 252 under the action of the negative pressure effect.

[0044] like Fig.10 , 11As shown in the figure, the wear chip removal device 3 is mainly composed of a connecting transition seat 31, a bearing seat 32, an annular chip removal belt 33 and a third power unit 34. The bearing seat 32 is used to bear the third power unit 34, and it is connected to the transition seat 31 to achieve a fixed connection with the X-axis sliding table 41. The third power unit 34 includes a stepper motor 341 and a plane fixed axis gear train 342. The annular chip removal belt 33 is sleeved on the plane fixed axis gear train 342 and is kept in a tensioned state. The stepper motor 341 is installed on the bearing seat 32, and is used as a power supply source for the plane fixed axis gear train 342. In actual application, after the R angle grinding of the ceramic splitting cutter is completed, the grinding chip removal device 3 performs an X-direction displacement movement under the carrying force from the combined carrier 4 until it is aligned with the ceramic splitting cutter, and then performs a Y-direction displacement movement under the carrying force from the combined carrier 4 until the ceramic splitting cutter partially penetrates the annular chip removal belt 33. The annular chip removal belt 33 is partially concave or partially torn due to the insertion force from the ceramic splitting cutter. In this process, the remaining chips on the ceramic splitting cutter are The grinding chips are removed under the action of the holding force; after the R-angle profiling of the ceramic splitting cutter and the removal of the grinding chips, the workpiece is transferred from the workpiece head 1 to the processed workpiece carrying unit 6 with the help of the free-degree-of-freedom picking robot 7; then, the rotor of the stepper motor 341 moves forward one step, and the annular chip removal belt 33 rotates at a fixed angle under the action of the rotational torque, and the new unused area is replaced by the insertion and the old area is partially sunken and deformed or partially torn to welcome the next ceramic splitting cutter whose R-angle has been profiled but the grinding chips have not been removed.

[0045] According to different models and specifications of the ceramic splitting cutter, the annular chip removing belt 33 can be preferably made of foam or rubber.

[0046] Depend on Fig.10 It can also be clearly seen from the figure that the plane fixed axis gear train 342 is composed of a driving gear 3421, a first driven gear 3422 and a second driven gear 3423. The driving gear 3421 is directly driven by the stepping motor 341. The first driven gear 3422 and the second driven gear 3423 are both meshed with the driving gear 3421, and the three are arranged linearly.

[0047] Furthermore, if Figure 2 , 3 As shown in 4, the ceramic splitting knife R angle profiling processing line is also equipped with a visual inspection microscope 9. The visual inspection microscope 9 is used to determine whether the profiling grinding device 2 occupies the correct processing position relative to the ceramic splitting knife, or to determine whether the formed R angle of the ceramic splitting knife meets the quality inspection standard, and it is arranged on one side of the profiling grinding device 2.

[0048] Finally, it should be noted that Figure 2 , 3As shown in , 4, the workpiece carrier unit 5 and the processed workpiece carrier unit 6 are placed adjacent to each other and are close to the workpiece headstock 1, so that all three are covered by the effective working radius of the multi-degree-of-freedom picking robot 7. And the workpiece carrier unit 5 is composed of a first workpiece carrier tool 51 and a second workpiece carrier tool 52. The processed workpiece carrier unit 6 is composed of a first processed workpiece carrier tool 61 and a second processed workpiece carrier tool 62. In this way, in actual application, the first workpiece carrier tool 51 and the second workpiece carrier tool 52 cooperate to continuously supply ceramic splitters in batches to the multi-degree-of-freedom picking robot 7 to ensure that the ceramic splitter picking action of the multi-degree-of-freedom picking robot 7 is not interrupted, that is, when the ceramic splitters carried by the first workpiece carrier tool 51 are emptied, they are replaced by the second workpiece carrier tool 52. At the same time, the first workpiece carrier tool 51 is supplemented by a new batch of ceramic splitters, and vice versa. The first machined part carrying tool 61 and the second machined part carrying tool 62 cooperate with each other, and the ceramic splitting knife picking action of the multi-degree-of-freedom picking robot 7 is not interrupted, even when one of the first machined part carrying tool 61 or the second machined part carrying tool 62 is fully loaded.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
