Description

Technical Field

[0001] The present application relates to the technical field of feeding equipment, and in particular to an automatic feeding device and a dicing machine. Background Art

[0002] The dicing machine is a high-precision industrial processing equipment, which is widely used in the production and manufacturing process of semiconductor wafers. It is mainly used for dicing and cutting of wafers, ceramics, glass and other materials. With the continuous improvement of automation requirements, the demand for automatic loading of dicing machines has also increased significantly. The use of automatic loading devices can significantly improve production efficiency, reduce labor costs, and ensure the stability of product quality.

[0003] The dicing machine, also known as a precision grinding wheel cutting machine, is a precision CNC equipment that integrates water-gas-electric, air-static high-speed spindle, precision mechanical transmission, sensors and automatic control technologies. It is mainly used for dicing and cutting materials such as silicon integrated circuits, light-emitting diodes, lithium niobate, piezoelectric ceramics, gallium arsenide, sapphire, aluminum oxide, iron oxide, quartz, glass, ceramics, solar cells, etc. The working principle of the dicing machine is mainly to use a high-speed rotating grinding wheel to cut the material. The motor drives the grinding wheel to rotate at high speed, places the material on the loading plate, and accurately guides the grinding wheel to move through the guide rail so that it contacts the material to achieve cutting.

[0004] A tension ring, also known as a wafer bonding ring or a tension ring, is a tool used to fix and tighten the blue film of special materials. In semiconductor processing, especially in the wafer cutting process, in order to protect the photolithography circuit on the front of the wafer from damage, it is usually necessary to attach a layer of blue film to the front of the wafer. Since the blue film itself has no strength, it needs to be tightened with the help of a tension ring to ensure that the wafer can remain flat during the processing, which is conducive to the placement of the device.

[0005] With the continuous improvement of automation requirements, the demand for automatic loading of dicing machines has also increased significantly, so that dicing machines can significantly improve production efficiency, reduce labor costs, and ensure stable product quality. The traditional automatic loading device is that the conveying mechanism takes out the tension ring from the material box, and then the conveying mechanism directly places the tension ring on the suction cup. However, since the position of the tension ring may deviate during the process of the conveying mechanism taking out the tension ring from the material box, there will be deviation when the tension ring is placed on the suction cup, which affects the quality of dicing.

[0031] In order to better explain the present application and facilitate understanding, the present application is described in detail below in conjunction with the accompanying drawings through specific implementation methods. The directional terms such as "upper", "lower", "left", "right", "front" and "back" mentioned in this document are used in the following manner. Figure 1 ,and Figure 4The position of the transport mechanism 3 relative to the calibration mechanism 2 is defined as "up"; the position of the first clamping plate 22 relative to the second clamping plate 23 is defined as "left"; the position of the calibration mechanism 2 relative to the magazine lifting mechanism 1 is defined as "front".

[0032] The following describes an automatic loading device according to some embodiments provided by the present application with reference to the accompanying drawings.

[0033] See also Figures 1 to 8 An automatic feeding device provided in an embodiment of the first aspect of the present application includes: a material box lifting mechanism 1, a calibration mechanism 2, a conveying mechanism 3 and a workbench mechanism 4, the material box lifting mechanism 1 is arranged on one side of an operating table 6, the calibration mechanism 2, the conveying mechanism 3 and the workbench mechanism 4 are respectively arranged on the operating table 6, the material box lifting mechanism 1, the calibration mechanism 2, the conveying mechanism 3 and the workbench mechanism 4 are arranged in sequence along a straight line; the conveying mechanism 3 is used to take the tension ring out of the material box lifting mechanism 1, put it into the calibration mechanism 2 for positioning and calibration, and then put it into the workbench mechanism 4.

[0034] There are multiple grids in the material box 5, each grid is placed with a tension ring, and the material box 5 is placed on the material box lifting mechanism 1. When processing starts, the material box lifting mechanism 1 needs to be lowered so that the first grid of the material box 5 is aligned with the conveying mechanism 3. When the conveying mechanism 3 takes out the tension ring from the first grid of the material box 5 and completes the processing, the material box lifting mechanism 1 needs to rise to the height of one grid so that the second grid of the material box 5 is aligned with the conveying mechanism 3, and then the above process is repeated until the tension rings of all grids in the material box 5 are processed.

[0035] The material box lifting mechanism 1 includes: a lifting frame 11, a back plate 12, a lifting component 13 and a material box placement platform 14, the back plate 12 is vertically arranged on the lifting frame 11; the lifting component 13 is arranged on the back plate 12; the material box placement platform 14 is arranged on the lifting component 13; the lifting component 13 is used to drive the material box placement platform 14 to rise or fall.

[0036] The material box 5 is placed on the material box placement platform 14. When the lifting component 13 drives the material box placement platform 14 to rise, the material box 5 also rises; when the lifting component 13 drives the material box placement platform 14 to descend, the material box 5 also descends.

[0037] In an illustrative embodiment, Figure 3 As shown, the lifting assembly 13 includes: a first slide rail 131, a slide plate 132, a screw rod 133 and a servo motor 134, the first slide rail 131 is arranged on the back plate 12; the slide plate 132 is arranged on the first slide rail 131; the screw rod 133 is threadedly connected to the slide plate 132; the output end of the servo motor 134 is connected to the screw rod 133.

[0038] The back plate 12 is a platform for providing support, and is usually made of a solid material, such as a metal plate or a plastic plate, to ensure its stability and load-bearing capacity. The first slide rail 131 provides necessary support and guidance for the slide 132, ensuring that the slide 132 can stably move along a predetermined track, that is, the slide 132 can move up and down along the first slide rail 131. The stability and guidance provided by the first slide rail 131 help prevent the slide 132 from deflecting or shaking during the sliding process. The screw rod 133 is a transmission element that converts rotary motion into linear motion, which can achieve high-precision linear motion, and is relatively simple to maintain and has a long service life. The servo motor 134 is a motor that can accurately control position, speed and acceleration, and can accurately control the position and speed of the rotor according to the control signal to achieve high-precision motion control. The servo motor 134 drives the screw rod 133 to rotate through its precise control ability, and then converts the rotary motion into the linear motion of the slide 132, so that the slide 132 can be accurately controlled to rise or fall. The material box placement platform 14 is horizontally arranged and is fixedly connected to the slide 132 via a connecting plate 141 . The rise or fall of the slide 132 drives the material box placement platform 14 to rise or fall.

[0039] Furthermore, a cover plate 15 is provided on the top of the back plate 12, and the cover plate 15 is used to protect the lifting assembly 13 and prevent pollutants such as dust and oil from directly contacting the components or equipment below.

[0040] Furthermore, a positioning block is provided on the material box placement platform 14 , and the positioning block is used to locate the placement position of the material box 5 , which can improve the accuracy of the placement of the material box 5 .

[0041] In an illustrative embodiment, Figure 2 and Figure 7 As shown, the material box lifting mechanism 1 also includes: a first edge sensor 16 and a second edge sensor 17, the first edge sensor 16 is arranged on the top of the back plate 12, and the first edge sensor 16 is located at the edge position away from the calibration mechanism 2; the second edge sensor 17 is arranged on the operating table 6, and the second edge sensor 17 is located at the edge position close to the second clamping plate 23; the first edge sensor 16 is used to detect whether there is an object at the edge of the material box lifting mechanism 1 away from the calibration mechanism 2; the second edge sensor 17 is used to detect whether there is an object at the edge of the material box lifting mechanism 1 close to the second clamping plate 23.

[0042] The detection directions of the first edge sensor 16 and the second edge sensor 17 are as follows: Figure 7The edge positions indicated by the two arrows, i.e., the edge position of the material box lifting mechanism 1 away from the calibration mechanism 2 and the edge position close to the second clamping plate 23, are the two positions that operators easily pass by when the device is working, causing human error or personal injury. The first edge sensor 16 and the second edge sensor 17 can detect whether there is anyone passing by these two edge positions when the device is working. If there is someone, the device can be stopped to prevent human error or personal injury.

[0043] The first edge sensor 16 and the second edge sensor 17 can be infrared distance measuring sensors, which are sensors that use infrared technology for non-contact distance measurement, and calculate the distance between the target object and the sensor by measuring the time required for the infrared signal to be transmitted and received. The infrared distance measuring sensor does not need to be in direct contact with the object being measured during the measurement process, thus avoiding friction and wear caused by contact; by accurately measuring the round-trip time or intensity of the infrared signal, it can achieve high-precision distance measurement; it can adapt to different types of target objects, and can accurately measure whether the target object is bright, dark, reflective or absorptive; it has strong anti-environmental interference ability, and can eliminate the influence of external light sources, smoke and dust on the measurement results.

[0044] In an illustrative embodiment, Figure 8 As shown, the material box lifting mechanism 1 also includes: an infrared transmitter 18 and an infrared receiver 19, which are respectively arranged at the edge of the operating table 6 close to the material box lifting mechanism 1, and the infrared transmitter 18 and the infrared receiver 19 are respectively located on both sides of the material box 5; the infrared transmitter 18 and the infrared receiver 19 are used to detect whether there is an object near the calibration mechanism 2 when the material box 5 is close to the calibration mechanism 2.

[0045] The infrared transmitter 18 is located above the material box 5, and the infrared receiver 19 is located below the material box 5. The infrared transmitter 18 transmits infrared rays, which are received by the infrared receiver 19. With this design, when the tension ring in the material box 5 leaves the material box 5 due to unexpected factors, the infrared rays between the infrared transmitter 18 and the infrared receiver 19 will be blocked, and the existence of the tension ring can be detected, and the material box lifting mechanism 1 can be controlled to stop rising or falling to prevent the tension ring from being damaged by collision. It is understandable that the positions of the infrared transmitter 18 and the infrared receiver 19 can be swapped, and the same technical effect can be achieved.

[0046] The calibration mechanism 2 includes: a fixed plate 21, a first clamping plate 22, a second clamping plate 23 and a clamping assembly 24. The first clamping plate 22 and the second clamping plate 23 are arranged in parallel on both sides of the fixed plate 21; the first clamping plate 22 is fixedly connected to the fixed plate 21, and the second clamping plate 23 is slidably connected to the fixed plate 21 through the clamping assembly 24; the clamping assembly 24 is used to drive the second clamping plate 23 away from or close to the first clamping plate 22.

[0047] The first clamping plate 22 and the second clamping plate 23 are arranged in parallel. When the tension ring is placed on the first clamping plate 22 and the second clamping plate 23, the flat edges on both sides of the tension ring will correspond to the first clamping plate 22 and the second clamping plate 23. The first clamping plate 22 is fixed and the clamping assembly 24 drives the second clamping plate 23 to approach the first clamping plate 22, so that the tension ring is pushed to a fixed position next to the first clamping plate 22. At the same time, the clamping of the first clamping plate 22 and the second clamping plate 23 will calibrate the flat edges on both sides of the tension ring, thereby solving the technical problem that the position of the tension ring may deviate.

[0048] In an illustrative embodiment, Figure 4 As shown, the clamping assembly 24 includes: a second slide rail 241, a linear cylinder 242 and a limit block 243. The second slide rail 241 is arranged on the fixed plate 21, and the second clamping plate 23 is arranged on the second slide rail 241; the output end of the linear cylinder 242 is connected to the second clamping plate 23, and the linear cylinder 242 is used to drive the second clamping plate 23 to move on the second slide rail 241; the limit block 243 is arranged on the fixed plate 21, and the limit block 243 is used to limit the moving stroke of the second clamping plate 23 on the second slide rail 241.

[0049] The travel direction of the second slide rail 241 is perpendicular to the straight line where the second clamping plate 23 is located. This arrangement allows the second clamping plate 23 to only move closer to or farther from the first clamping plate 22 when moving on the second slide rail 241, without displacement in the front-to-back direction. The linear cylinder 242 is a common pneumatic actuator, and its working principle is based on the hydraulic or air pressure principle, which converts pneumatic energy into mechanical energy to achieve linear motion. The output end of the linear cylinder 242 can drive the second clamping plate 23 to move on the second slide rail 241. The limit block 243 prevents the linear cylinder 242 from moving for a long time, which will produce a certain distance deviation. It is necessary to limit the cylinder movement stroke, and at the same time, the workpiece positioning can be more accurate.

[0050] In an exemplary embodiment, a plurality of workpiece sensors 25 are provided on the first clamping plate 22, and the workpiece sensors 25 are used to detect whether the flat edge of the tension ring is aligned. For example, two workpiece sensors 25 are provided to sense the position of the flat edge of the tension ring to detect whether the tension ring is placed correctly.

[0051] In an illustrative embodiment, a plurality of material scanning sensors 26 are provided on the fixed plate 21, and the material scanning sensors 26 are used to detect whether there are tension rings on the first clamping plate 22 and the second clamping plate 23. For example, two material scanning sensors 26 are provided to scan the edge of the tension ring, and the conveying mechanism 3 will not convey the material until both of the material scanning sensors 26 have detected the edge of the tension ring.

[0052] In an exemplary embodiment, a plurality of eccentric wheels 27 are provided on the second clamping plate 23, and the eccentric wheels 27 are used to adjust the position of the flat edge of the tension ring. For example, two eccentric wheels 27 are provided to facilitate installation and debugging, and prevent equipment alarm or material pulling problems caused by inaccurate positioning of the flat edge of the tension ring.

[0053] In an illustrative embodiment, Figure 5 and Figure 6 As shown, the workbench mechanism 4 includes: a suction cup 41 and a clamping assembly 42, the suction cup 41 is arranged on the operating table 6, and the clamping assembly 42 is arranged around the suction cup 41; the clamping assembly 42 includes: a pressing plate 421, a rotary cylinder 422 and a mounting frame 423, the mounting frame 423 is arranged around the suction cup 41, the rotary cylinder 422 is arranged on the mounting frame 423, and the pressing plate 421 is arranged at the output end of the rotary cylinder 422.

[0054] The clamping assembly 42 is used to clamp the edge of the tension ring. When the transport mechanism 3 places the tension ring on the suction cup 41, the pressure plate 421 is driven by the rotary cylinder 422 to flip upward to clamp the edge of the tension ring to prevent the tension ring from moving during the dicing process; when the dicing is completed, the pressure plate 421 is driven by the rotary cylinder 422 to flip downward to loosen the edge of the tension ring, making it easier for the transport mechanism 3 to transport the tension ring.
