Technical Field

[0001] This utility model relates to the field of suction head assembly technology, specifically a high-precision suction head assembly mounting calibration plate. Background Technology

[0002] Semiconductor devices, characterized by high output power, small size, light weight, long lifespan, and high photoelectric conversion efficiency, are widely used in various fields. Their main internal component is the semiconductor chip. In use, semiconductor chips are typically arranged in linear, planar, or stacked arrays. The light emitted by each chip is spatially combined to achieve the beam emission function of the semiconductor device. During the inspection and packaging process, semiconductor chips undergo multiple processing steps, requiring loading, unloading, or transfer between different carriers. The common practice is to use suction head assemblies for adsorption and transfer.

[0003] In existing suction head assemblies, the suction head and suction cup are installed at the bottom of a hollow stepper motor and are ventilated through an air tube. However, during long-term use, the suction cup and suction head installed at the bottom of the hollow stepper motor may become misaligned or have a different height, causing changes in the height of the suction cup and suction head, which affects the adsorption of semiconductor chips.

[0004] Therefore, a high-precision suction head assembly mounting calibration plate is proposed to solve the problems mentioned above. Utility Model Content

This deviation causes changes in the height of the suction cup and suction head, affecting the adsorption of semiconductor chips.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision suction head assembly mounting calibration plate, comprising a hollow stepper motor body, a hollow rotating shaft passing through the middle of the hollow stepper motor body, an air pipe connector connected to the top end of the hollow rotating shaft, an air guiding mechanism installed at the bottom end of the hollow rotating shaft, a buffer calibration mechanism provided between the top end of the air guiding mechanism and the bottom end of the hollow rotating shaft, a suction head installed at the bottom end of the air guiding mechanism, and a suction cup tightly fitted at the bottom end of the suction head; The air guiding mechanism includes an air guiding plate and an air guiding pipe. A cover plate is installed on the top of the air guiding plate, and the air guiding pipe passes vertically through the cover plate, with its top end tightly slidably inserted into the bottom of the hollow rotating shaft. The buffer calibration mechanism includes a calibration plate and a calibration rod. The calibration plate is fixed to the surface of the air guide tube, and the calibration rod is uniformly fixed to the top edge of the calibration plate. A connecting plate is uniformly fixed to the bottom end of the surface of the hollow rotating shaft, and the calibration rod slides through the outer end of the connecting plate.

[0007] Preferably, the calibration plate is a circular plate structure and is horizontally set at the top of the cover plate. A second sealing gasket is adhered to the bottom of the cover plate. The second sealing gasket tightly abuts against the top of the air guide plate. The calibration rod is vertically set, and the connecting plate is horizontally set and distributed in a cross shape.

[0008] Preferably, a spring is fitted onto the surface of the air guide tube, and an abutment ring is connected to the top of the spring. The abutment ring is slidably fitted onto the surface of the air guide tube and abuts against the bottom end of the hollow rotating shaft. The spring is located between the calibration plate and the hollow rotating shaft.

[0009] Preferably, the outer end of the connecting plate has a first connecting hole, the calibration rod is a threaded rod structure and passes vertically through the first connecting hole, and a first nut is connected to the surface of the calibration rod at the top of the first connecting hole.

[0010] Preferably, the air guide plate is a hollow plate structure and is horizontally arranged, with a second connecting hole at its bottom edge. The second connecting hole is a threaded hole structure, and the suction head is an externally threaded tube structure that is threaded into the second connecting hole. The suction head is vertically arranged, and the suction cup is horizontally arranged.

[0011] Preferably, a first sealing gasket is fitted onto the surface of the suction head, the first sealing gasket abuts against the bottom end of the second connecting hole, a connecting bracket is slidably mounted on the surface of the suction head, the connecting bracket abuts against the bottom end of the first sealing gasket, and a second nut is connected to the surface of the suction head at the bottom end of the connecting bracket.

[0012] Preferably, the connecting frame has a cross-shaped structure and is horizontally arranged, with a third connecting hole at its outer end. A connecting rod is connected to the bottom end of the air guide plate and located around the second connecting hole. The connecting rod slides through the third connecting hole, and a third nut is connected to the bottom end of the connecting rod and located at the bottom end of the connecting frame.

[0013] Compared with the prior art, this utility model provides a high-precision suction head assembly mounting calibration plate, which has the following beneficial effects: 1. A hollow rotating shaft passes through the middle of a hollow stepper motor. Its top end is connected to an external air source through an air pipe connector for ventilation. An air guide tube is tightly slid into the bottom end of the hollow rotating shaft. A cover plate and an air guide plate are installed at the bottom end of the air guide tube. Furthermore, a spring and an abutment ring are sleeved on the surface of the air guide tube. Therefore, suction cups and suction heads can be evenly installed at the bottom end of the air guide plate, and the spacing is elastic to keep the suction cups and suction heads abutting and adsorbing semiconductor chips.

[0014] 2. A calibration plate is fixed on the surface of the air guide tube, and a calibration rod is fixed at the top of the calibration plate. The top of the calibration rod slides through the surface of the connecting plate at the bottom of the hollow rotating shaft, thereby stabilizing the height of the air guide plate, suction cup and suction head, and preventing the air guide plate, suction cup and suction head from tilting. Moreover, the different heights of the air guide plate, suction cup and suction head can be adjusted and the level can be calibrated.

[0015] 3. The suction head can be detachably installed at the bottom of the air guide plate through the second connecting hole, and the connecting bracket slides onto the surface of the suction head. Therefore, after the suction head is tightly and stably connected by the second nut and the sealing gasket, the connecting rod passes through the outer end of the connecting bracket and is fastened by the third nut. This allows the suction head to be aligned vertically and stably installed, avoiding shaking and tilting, and ensuring that the suction cup and suction head can stably and accurately adsorb semiconductor chips.

A cover plate 9 is installed on the top of the air guiding plate 10, and the air guiding pipe 8 passes vertically through the cover plate 9. Its top end is tightly slidably inserted into the bottom of the hollow rotating shaft 2. A spring 6 is fitted onto the surface of the air duct 8. A contact ring 14 is connected to the top of the spring 6. The contact ring 14 is slidably fitted onto the surface of the air duct 8 and abuts against the bottom of the hollow rotating shaft 2. The spring 6 is located between the calibration plate 7 and the hollow rotating shaft 2.

[0020] The hollow rotating shaft 2 passes through the middle of the hollow stepper motor 1, and its top end is connected to an external air source through the air pipe connector 3 for ventilation. The air guide pipe 8 is tightly slidably inserted into the bottom end of the hollow rotating shaft 2, and a cover plate 9 and an air guide plate 10 are installed at the bottom end of the air guide pipe 8.

[0021] Furthermore, a spring 6 and an abutment ring 14 are fitted onto the surface of the air guide tube 8, so that the suction cup 11 and the suction head 16 can be evenly installed at the bottom end of the air guide plate 10, and the spacing is elastically expandable to keep the suction cup 11 and the suction head 16 abutting and adsorbing the semiconductor chip.

[0022] In detail, the buffer calibration mechanism includes a calibration plate 7 and a calibration rod 4. The calibration plate 7 is fixed on the surface of the air duct 8, and the calibration rod 4 is evenly fixed on the top edge of the calibration plate 7. A connecting plate 5 is evenly fixed on the bottom end of the surface of the hollow rotating shaft 2, and the calibration rod 4 slides through the outer end of the connecting plate 5.

[0023] The calibration plate 7 is a circular plate structure and is horizontally set at the top of the cover plate 9. The bottom of the cover plate 9 is bonded with a second sealing gasket 12, which is tightly abutted against the top of the air guide plate 10. The calibration rod 4 is set vertically, and the connecting plate 5 is set horizontally and distributed in a cross shape.

[0024] The outer end of the connecting plate 5 is provided with a first connecting hole 13. The calibration rod 4 is a threaded rod structure and passes vertically through the first connecting hole 13.

[0025] In this process, a calibration plate 7 is fixed on the surface of the air duct 8, and a calibration rod 4 is fixed at the top of the calibration plate 7. Therefore, the top of the calibration rod 4 slides through the surface of the connecting plate 5 at the bottom of the hollow rotating shaft 2.

[0026] In this way, the height of the air guide plate 10, suction cup 11 and suction head 16 can be stably calibrated, and the air guide plate 10, suction cup 11 and suction head 16 can be prevented from tilting. Moreover, the different heights of the air guide plate 10, suction cup 11 and suction head 16 can be adjusted and the level can be calibrated.

[0027] Finally, the air guide plate 10 is a hollow plate structure and is set horizontally. It has a second connecting hole 17 at its bottom edge.

A connecting bracket 23 is slidably mounted on the surface of the suction head 16, and the connecting bracket 23 abuts against the bottom end of the first sealing gasket 21. A second nut 22 is connected to the surface of the suction head 16 at the bottom end of the connecting bracket 23.

[0029] The connecting frame 23 has a cross-shaped structure and is horizontally arranged. A third connecting hole 20 is opened at its outer end. A connecting rod 18 is connected to the bottom end of the air guide plate 10 and around the second connecting hole 17. The connecting rod 18 slides through the third connecting hole 20. A third nut 19 is connected to the bottom end of the surface of the connecting rod 18 and at the bottom end of the connecting frame 23.

[0030] The suction head 16 is detachably installed at the bottom of the air guide plate 10 through the second connecting hole 17, and the connecting frame 23 is slidably sleeved on the surface of the suction head 16. Therefore, after the suction head 16 is tightly and stably connected to the first sealing gasket 21 through the second nut 22, the connecting rod 18 passes through the outer end of the connecting frame 23 and is fastened by the third nut 19.

[0031] In this way, the suction head 16 can be calibrated to be installed vertically and stably, avoiding shaking and tilting, and ensuring that the suction cup 11 and the suction head 16 can stably and accurately adsorb the semiconductor chip.
