Description

Technical Field

[0001] The present invention relates to the technical field of dicing machines, and in particular to a multi-station grinding wheel dicing machine. Background Art

[0002] The grinding wheel dicing machine mainly uses an electric spindle to drive the ultra-thin grinding wheel blade to rotate at high speed (usually thousands to tens of thousands of revolutions per minute), combined with the movement of a precision worktable to mechanically cut the material. During the dicing operation, coolant (such as water-based or oil-based coolant) needs to be sprayed to reduce the cutting temperature, reduce dust and extend the life of the grinding wheel. Its core structure is mainly composed of a spindle system, a worktable, a grinding wheel blade, a visual system and a control system. The spindle system uses a high-precision electric spindle to ensure the high-speed and stable rotation of the grinding wheel. The worktable uses a precision motion platform (X / Y / Z axis) to control the cutting position and depth with an accuracy of up to micron level. The grinding wheel blade is made of diamond or silicon carbide, with a thickness of usually 10-500 microns, suitable for different materials. The visual system uses a high-resolution camera to assist in positioning to ensure that the cutting is aligned with the mark (such as the cutting path of the wafer). The control system uses a numerical control (CNC) system or automation software to achieve parameter setting and process control. It is mainly used in semiconductor manufacturing, electronic component processing, precision ceramic / glass processing and new energy fields.

[0003] Most of the existing grinding wheel dicing machines only have a single station for grinding wheel dicing operations. Before and after the dicing operation, it is necessary to load and unload the materials at the dicing machine station, and it is also necessary to ensure the accurate distribution of the raw materials to ensure the accuracy of the dicing operation. During the loading and unloading operations, the dicing machine must stop working. During the production process, if it is necessary to perform dicing operations on multiple pieces of raw materials, the single-station grinding wheel dicing machine has low working efficiency and takes a long time. Therefore, the present invention provides a multi-station grinding wheel dicing machine to meet the needs. Summary of the invention

[0004] In view of the above problems, the present invention provides a multi-station grinding wheel dicing machine.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-station grinding wheel dicing machine, comprising a machine base, a rotatable turntable is provided on the machine base, a dicing unit is provided above the center of the turntable, and three equidistantly distributed trays are provided on the turntable along a circular trajectory, the trays are fixedly installed with connecting frames, and power supports that can carry them to slide along a straight path are fixedly installed below the connecting frames, and as the turntable rotates counterclockwise, the three trays rotate synchronously; during the rotation process, the power support carries the connecting frame and the tray to move, and pushes the tray originally located on the periphery of the dicing unit to below the dicing unit.

[0006] A loading suction cup and a unloading suction cup are provided at the rear of the dicing unit. The loading suction cup and the unloading suction cup are respectively located directly above two trays distributed from left to right behind the dicing unit. The trays processed by the dicing unit can be moved successively to directly below the unloading suction cup and the loading suction cup. The unloading suction cup and the loading suction cup perform unloading operations and replenishing operations on the processed silicon wafers in the tray.

[0007] Furthermore, the dicing unit includes a powered grinding wheel disposed above the turntable and a driving unit installed with the powered grinding wheel, and a top plate is installed on the top of the driving unit.

[0008] Furthermore, a linkage gear ring is provided at the bottom end of the turntable, and the inner ring teeth of the linkage gear ring are meshed and connected with an electric drive gear 1. The electric drive gear 1 is installed on a machine base, and a support base matched with the linkage gear ring is provided on the machine base. When the linkage gear ring and the turntable rotate synchronously with the electric drive gear 1, the three power brackets carrying the connecting frame and the tray rotate synchronously.

[0009] Furthermore, the power supports are all U-shaped structures, and the inner sides of the power supports are connected to the electric drive gear 2 through rack meshing. The electric drive gear 2 is installed on the turntable through a pressure plate. The power support legs are all located on the inner side of the pressure plate. The turntable is provided with guide rails that match the power supports. When the power supports and the connecting frame move along a straight path with the rotation of the electric drive gear 2, the pallet can move closer to or away from the bottom of the power grinding wheel.

[0010] Furthermore, a mounting plate is fixed on the loading suction cup and the unloading suction cup, a hanger parallel to the mounting plate is provided above the mounting plate, a cylinder for controlling the lifting and lowering movement of the mounting plate is provided on the hanger, and a limiting rod running through the hanger is provided on the mounting plate. When the loading suction cup and the unloading suction cup descend synchronously with the mounting plate, the two trays distributed from left to right behind the dicing unit can be respectively discharged and sucked.

[0011] Furthermore, one side of the hanger is connected to a synchronous gear 1 through a rack meshing, and the synchronous gear 1 is connected to a synchronous gear 2 that rotates synchronously with the synchronous gear through a linkage shaft. The synchronous gear 2 is located above the synchronous gear 1, and two hanging rails that are compatible with the hanger are provided under the top plate. When the synchronous gear 1 and the synchronous gear 2 rotate, the hanger and the mounting plate move along the distribution direction of the hanging rails.

[0012] Furthermore, the top plate is provided with an electric synchronous gear ring meshing with two synchronous gears on the same circular path, and the linkage shafts are connected to the top plate through bearing seats. When the two synchronous gears rotate in the same direction as the electric synchronous gear ring rotates, the two hangers and the mounting plate can move along the distribution direction of the connecting frame located therebelow until the loading suction cup and the unloading suction cup synchronously approach or move away from the pallet.

[0013] Furthermore, a loading tray and a receiving tray are respectively provided at the left and right ends of the machine base. The loading tray and the receiving tray are both distributed under two trays distributed from left to right behind the dicing unit. When the loading suction cup moves close to the tray, the material body in the loading tray can be transferred to the inner side of the tray; when the unloading suction cup moves away from the tray, the material body in the tray can be transferred to the inner side of the receiving tray.

[0014] In summary, the technical effects and advantages of the present invention are as follows: 1. During the operation of the multi-station grinding wheel dicing machine, when the dicing unit performs dicing processing on the material in the tray below it, the two trays behind it can be respectively supplemented and unloaded, saving the time required for loading and unloading operations. During the unloading and supplementing operations, the normal operation of the dicing unit is not affected, and the efficiency of dicing processing is improved during the continuous dicing operation of multiple raw materials.

[0015] 2. The present invention can not only quickly and stably implement the feeding operation, but also facilitate the collection operation of the processed material body quickly and stably. It can save the time required for feeding and unloading operations, improve the accuracy of feeding and unloading operations, and improve the working efficiency of feeding and unloading operations.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Reference Figure 1-3 The multi-station grinding wheel dicing machine shown comprises a machine base 1, a rotatable turntable 2 is arranged on the machine base 1, and a dicing unit is arranged above the center of the turntable 2. The dicing unit can perform dicing operation on the material body below it until the material body is processed.

[0029] In the present invention, three equally spaced trays 4 are arranged on the turntable 2 along the circumferential track, and the trays 4 are fixedly mounted with connecting frames 5, and a power bracket 6 capable of carrying the trays 4 to slide along a straight path is fixedly mounted below the connecting frames 5. In the actual use of the multi-station grinding wheel dicing machine, the tray 4 located on the left side behind the dicing unit is located at the feeding station, and the tray 4 located on the right side is located at the unloading station.

[0030] In the initial state, in the feeding station, it is necessary to perform a feeding operation on the tray 4 located to the left of the rear of the dicing unit. At this time, the other two trays 4 are in an empty state. As the turntable 2 rotates counterclockwise, the three trays 4 rotate in sequence, so that the tray 4 that has completed the first feeding in the feeding station can be rotated to the bottom of the dicing unit to receive the first dicing operation from the dicing unit. During the first rotation of the turntable 2, the empty tray 4 originally located at the unloading station rotates to the feeding station; and the empty tray 4 located in front of the dicing unit rotates to the unloading station.

[0031] During the rotation process, the power bracket 6 and the connecting frame 5 need to carry the tray 4 and move synchronously along the straight path to achieve the purpose of smoothly pushing the tray 4 originally located on the outer peripheral ring line of the dicing unit to the bottom of the dicing unit, see Figure 3 , Figure 4 shown.

[0032] During the first dicing operation, the second loading operation is repeated on the empty tray 4 in the replenishing station. Since the tray 4 in the unloading station is still in an empty state at this time, there is no need to perform any operation on the tray.

[0033] After the first dicing operation is completed, the turntable 2 rotates counterclockwise again, so that the tray 4 after dicing is rotated to the unloading station behind the dicing unit. At this time, the tray 4 for the second loading operation in the refilling station is transferred to the bottom of the dicing unit again to receive the second dicing operation; the empty tray 4 originally in the unloading station is rotated to the refilling station. Therefore, during the second dicing operation, the refilling station and the unloading station can synchronously perform the refilling and unloading operations on the empty tray 4 and the full tray 4 located below them respectively.

[0034] During the second rotation of the turntable 2, the power bracket 6 and the pallet 4 carried by the connecting frame 5 move synchronously along a straight path, returning the pallet 4 originally located in front of the dicing unit to the outer peripheral ring line of the dicing unit to ensure that the pallet 4 is facing the unloading station.

[0035] Then, if Fig. 9As shown, in the subsequent working process of the multi-station grinding wheel dicing machine, when the dicing unit performs dicing processing operations on the material body in the tray 4 located below it, the two trays 4 located behind it can be respectively supplemented and unloaded, saving the time required for loading and unloading operations. With the continuous rotation of the turntable 2, it can be ensured that each time the dicing unit completes dicing on the tray 4 located below it, the empty tray 4 after unloading in the unloading station can be rotated to the supplementary station to wait for the supplementary operation; the tray 4 after the filling in the filling station can be quickly supplemented to the bottom of the dicing unit to wait for the dicing processing operation; the tray 4 that has been processed can be quickly transferred to the unloading station to wait for the unloading operation. In the process of unloading and supplementing operations, the normal operation of the dicing unit is not affected, and the efficiency of the dicing process is improved in the process of continuous dicing operations on multiple pieces of raw materials.

[0036] It is worth noting that in the present invention, when the tray 4 moves from the feeding station to the part directly below the dicing unit, the tray 4 itself needs to rotate along the circumferential path under the force of the turntable 2, and also needs to move forward under the action of the connecting frame 5 and the power support 6. When the tray 4 after the dicing process is transferred to the unloading station, the tray 4 itself needs to rotate along the circumferential path under the force of the turntable 2, and also needs to move backward under the action of the connecting frame 5 and the power support 6, so as not to occupy the operating space of the dicing unit, and to facilitate the smooth implementation of the unloading operation.

[0037] like Figure 5 As shown, in order to be able to perform replenishment and unloading operations on the two trays 4 behind the dicing unit, in the present invention, a loading suction cup 7 and a unloading suction cup 8 are provided behind the dicing unit. The loading suction cup 7 and the unloading suction cup 8 are respectively located directly above the two trays 4 distributed from left to right behind the dicing unit. The trays 4 processed by the dicing unit can be moved successively to directly below the unloading suction cup 8 and the loading suction cup 7. The unloading suction cup 8 and the loading suction cup 7 perform unloading and replenishment operations on the silicon wafers processed in the tray 4.

[0038] Specifically, Figure 6 As shown, the dicing unit includes a powered grinding wheel 41 disposed above the turntable 2, a driving unit 42 installed with the powered grinding wheel 41, and a top plate 17 is installed on the top of the driving unit 42. The top plate 17 supports the driving unit 42, and under the operation of the driving unit 42, the powered grinding wheel 41 can be driven to smoothly perform a dicing operation on the material body in the tray 4.

[0039] like Figure 3 , Figure 4As shown, a linkage gear ring 3 is provided at the bottom end of the turntable 2, and the inner ring teeth of the linkage gear ring 3 are meshedly connected with an electric drive gear 31, and the electric drive gear 31 is installed on the machine base 1. The machine base 1 is provided with a support seat 32 adapted to the linkage gear ring 3. When the linkage gear ring 3 and the turntable 2 rotate synchronously with the electric drive gear 31, the three power brackets 6 carrying the connecting frame 5 and the tray 4 rotate synchronously, so as to achieve the purpose of driving the tray 4 to switch positions.

[0040] like Figure 4 As shown, the power support 6 is in a U-shaped structure, and the inner side of the power support 6 is connected to the electric drive gear 2 61 through a rack meshing, and the electric drive gear 2 61 is installed on the turntable 2 through a pressure plate, and the power support 6 legs are located on the inner side of the pressure plate. The turntable 2 is provided with a guide rail 21 adapted to the power support 6. When the power support 6 and the connecting frame 5 move along a straight path with the rotation of the electric drive gear 2 61, the tray 4 can move closer to or away from the bottom of the power grinding wheel 41. With the rotation of the turntable 2, the tray 4 moved from the feeding station to the bottom of the power grinding wheel 41 can be smoothly pushed, and the tray 4 moved from the bottom of the power grinding wheel 41 to the unloading station can also be smoothly retracted, ensuring the smooth implementation of the dicing operation.

[0041] Embodiment 2: Based on embodiment 1, Figure 5-8 As shown, a mounting plate 9 is fixed on the loading suction cup 7 and the unloading suction cup 8, and a hanger 10 parallel to the mounting plate 9 is provided above the mounting plate 9. The hanger 10 is provided with a cylinder 14 which can control the lifting and lowering movement of the mounting plate 9, and the mounting plate 9 is provided with a limiting rod 15 which runs through the hanger 10. When the loading suction cup 7 and the unloading suction cup 8 are synchronously lowered with the mounting plate 9, the material discharge operation and the material suction operation can be respectively performed on the two trays 4 distributed from left to right behind the dicing unit.

[0042] like Figure 6 As shown, one side of the hanger 10 is connected to a synchronous gear 11 through a rack meshing, and the synchronous gear 11 is connected to a synchronous gear 2 12 that rotates synchronously with it through a linkage shaft 13. The synchronous gear 2 12 is located above the synchronous gear 11, and two hanging rails 18 that are compatible with the hanger 10 are provided below the top plate 17. When the synchronous gear 11 and the synchronous gear 2 12 rotate, the hanger 10 and the mounting plate 9 move along the distribution direction of the hanging rails 18. During the movement, the material outside the feeding station can be added to the inside of the tray 4, and the material in the tray 4 in the unloading station can be transported to the outside of the tray 4, so as to achieve the purpose of implementing the feeding and unloading operations.

[0043] like Figure 8As shown, in the present invention, in order to make the loading suction cup 7 and the unloading suction cup 8 quickly align with the pallet, and implement the feeding and unloading operations, an electric synchronous gear ring 16 meshing with the two synchronous gears 12 on the same circumferential path is provided on the top plate 17, and the linkage shaft 13 is connected to the top plate 17 through a bearing seat. When the two synchronous gears 12 rotate in the same direction with the rotation of the electric synchronous gear ring 16, the two hangers 10 and the mounting plate 9 can move along the distribution direction of the connecting frame 5 located below them until the loading suction cup 7 and the unloading suction cup 8 are synchronously close to or away from the pallet 4.

[0044] like Figure 3 , Figure 5 As shown, a loading tray 19 and a receiving tray 20 are respectively provided at the left and right ends of the machine base 1. The loading tray 19 and the receiving tray 20 are both distributed below the two trays 4 distributed from left to right behind the dicing unit. When the loading suction cup 7 moves close to the tray 4, the material body in the loading tray 19 can be transferred to the inner side of the tray 4; when the unloading suction cup 8 moves away from the tray 4, the material body in the tray 4 can be transferred to the inner side of the receiving tray 20.

[0045] Specifically, during the slicing operation, under the operating force of the synchronous gear ring 16, the two sets of synchronous gears 11 and 12 can rotate clockwise, and the two sets of mounting plates 9, the hanger 10 and the loading suction cup 7 and the unloading suction cup 8 connected thereto are all moved away from the tray 4 until the loading suction cup 7 and the unloading suction cup 8 are moved to the position directly above the loading tray 19 and the receiving tray 20 respectively.

[0046] When the dicing operation is completed, with the switching of the positions of the three trays 4, the processed trays 4 can be quickly transferred to the unloading station, and the empty trays 4 at the unloading station are moved to the refilling station. At this time, the mounting plate 9 connected to the loading suction cup 7 is lowered toward the loading tray 19 under the action of the cylinder 14, and the raw materials waiting for processing are sucked inside it and then raised. In this process, the unloading suction cup 8 is in a fixed state.

[0047] Subsequently, under the operating force of the synchronous gear ring 16, the two sets of synchronous gear 1 11 and the synchronous gear 2 12 can rotate clockwise, and the two sets of mounting plates 9, the hanger 10 and the loading suction cup 7 and the unloading suction cup 8 connected thereto are all moved close to the tray 4, and the loading suction cup 7 and the unloading suction cup 8 with the raw materials adsorbed are respectively moved to above the tray 4 in the feeding station and the unloading station.

[0048] Furthermore, the two cylinders 14 drive the two mounting plates 9 carrying the loading suction cup 7 and the unloading suction cup 8 to descend synchronously, and the loading suction cup 7 replenishes the raw materials into the inside of the tray 4 during the descent process. And the unloading suction cup 8 absorbs the material body in the tray 4 during the descent process. When the two cylinders 14 drive the two mounting plates 9 carrying the loading suction cup 7 and the unloading suction cup 8 to rise synchronously again, the loading suction cup 7 has successfully completed the material replenishment operation, and the unloading suction cup 8 successfully sucks the material body to be unloaded to the outside of the tray 4.

[0049] Finally, under the operating force of the synchronous gear ring 16, the two sets of synchronous gear 1 11 and the synchronous gear 2 12 rotate clockwise again, and the two sets of mounting plates 9, the hanger 10 and the loading suction cup 7 and the unloading suction cup 8 connected thereto move away from the tray 4 again, and the loading suction cup 7 and the unloading suction cup 8 with the material adsorbed thereon move to the position directly above the loading tray 19 and the receiving tray 20 respectively.

[0050] Subsequently, the mounting plate 9 connected to the unloading suction cup 8 is lowered toward the receiving tray 20 under the action of the cylinder, and the adsorbed material falls into the receiving tray 20, completing the material collection operation. During this process, the loading suction cup 7 is in a fixed state.

[0051] During the operation of the multi-station grinding wheel dicing machine, the above steps need to be repeated. During the implementation process, the time required for the feeding and unloading operations can be saved, and the accuracy of the feeding and unloading operations can be improved. While the feeding operation is carried out quickly and stably, it is also convenient to collect the processed material quickly and stably. The working efficiency of the feeding and unloading operations is improved, which is convenient for the centralized management of raw materials and processed materials.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
