Description

Technical Field

[0001] This utility model relates to the field of piezoelectric crystal technology, and in particular to a quartz crystal rod bonding device. Background Technology

[0002] Piezoelectric crystals, such as quartz crystals, are core materials for manufacturing electronic components. In their processing, crystal ingot bonding is a critical step, involving fixing the cut crystal ingot to a substrate or carrier using an adhesive to facilitate subsequent precision processing such as slicing, grinding, and polishing. During the bonding process of crystal blocks or ingots, angular deviations directly affect the frequency characteristics of the wafer, reducing the product yield. As the size and thickness of crystal blocks or ingots continue to increase, the requirements for crystal ingot bonding equipment are becoming increasingly demanding.

[0003] Existing crystal rod bonding equipment uses a fixed-position X-ray emitter at the top, and the bonding stage, which weighs tens of kilograms, is rotated by the main bearing at the bottom of the material stage. This method will cause horizontal sway when the crystal rod moves horizontally, which will cause the crystal surface of the crystal rod to tilt, and ultimately result in inaccurate angle.

[0004] In addition, existing crystal rod bonding equipment uses a Geiger counter tube in conjunction with an X-ray tube to obtain the angular position of the crystal rod to be bonded. However, the Geiger counter tube receives low signal strength and has poor signal stability, and cannot compensate for the intensity attenuation of the X-ray tube, which leads to a reduction in the lifespan of the X-ray tube.

[0005] Currently, existing crystal rod bonding equipment uses a spacer method when bonding multiple layers of crystal rods. After each layer is bonded, the material plate needs to be removed, a spacer added, and then the material plate reinstalled. This not only wastes a lot of time and manpower, but also may introduce errors due to multiple clamping operations. Utility Model Content

Detailed Implementation

[0032] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] This invention provides a quartz crystal rod bonding device, such as... Figure 1As shown, the device includes an upper and lower separate crystal rod detection and positioning mechanism and a moving material stage mechanism. The moving material stage mechanism includes a material plate 1, a material plate receiving plate 2, a translation component 3, and a lifting component 4. The bottom of the material plate receiving plate 2 is connected to the lifting component 4, and the lifting component 4 drives the material plate receiving plate 2 to move up and down. The lifting component 4 is connected to the translation component 3 through a translation plate 3-2, and the translation component 3 drives the material plate receiving plate 2 to move laterally. The power drive components of the translation component 3 and the lifting component 4 are connected to a PLC control system, which controls the movement of the translation component 3 and the lifting component 4, thereby controlling the lateral and longitudinal movement of the material plate receiving plate 2. This invention ensures the consistency of the angle of multi-layer bonded crystal rods by separating the crystal rod detection and positioning mechanism and the moving material stage mechanism into upper and lower parts.

[0034] Specifically, such as Figure 2 As shown, the translation component 3 of the moving platform mechanism includes a translation component base plate 3-1, a translation plate 3-2, a translation guide rail 3-3, a translation ball screw 3-4, and a translation stepper motor 3-5. The translation guide rail 3-3 is fixed between the translation component base plate 3-1 and the translation plate 3-2, and the translation component base plate 3-1 and the translation plate 3-2 are slidably connected to each other through the translation guide rail 3-3. The bottom of the translation plate 3-2 is also threadedly connected to the translation ball screw 3-4, which is connected to the translation stepper motor 3-5. The translation stepper motor 3-5 is connected to the PLC control system, which controls the translation stepper motor 3-5 to rotate the translation ball screw 3-4, thereby driving the translation plate 3-2 to move laterally.

[0035] The lifting assembly 4 of the moving material platform mechanism includes a first corner plate 4-1, a second corner plate 4-2, a lifting guide rail 4-3, a lifting ball screw 4-4, a position indicator plate 4-5, and a limit switch 4-6. The first corner plate 4-1 is fixedly connected to the translation plate 3-2, and the second corner plate 4-2 is fixedly connected to the material plate receiving plate 2. The first corner plate 4-1 and the second corner plate 4-2 are slidably connected through the lifting guide rail 4-3. A lifting ball screw 4-4 is also provided between the material plate receiving plate 2 and the translation plate 3-2. The lifting ball screw 4-4 is connected to a lifting motor, and the lifting motor is connected to a PLC control system. The PLC control system controls the lifting motor, causing the lifting ball screw 4-4 to rotate, thereby driving the material plate receiving plate 2 to move longitudinally.

[0036] To prevent the lifting assembly 4 from moving too far, a position indicator plate 4-5 can be provided on the second corner plate 4-2, and a limit switch 4-6 is provided on its opposite side. The limit switch 4-6 can be set to the position corresponding to the highest and lowest points of the lifting assembly 4. The limit switch 4-6 can be a mechanical limit element or an electrical limit element. When the limit switch 4-6 is an electrical limit element, it is connected to the PLC control system. When the lifting assembly 4 triggers the limit switch 4-6, the PLC control system controls the lifting motor to stop.

[0037] Elastic clamps 5 and a reference plate 6 are fixedly mounted on opposite sides of the material plate receiving plate 2, with the material plate 1 placed between the elastic clamps 5 and the reference plate 6. More specifically, a pad 9 can be provided on the material plate receiving plate 2. During operation, the material plate 1 is placed on the pad 9 on the material plate receiving plate 2, with one side pressed against the reference plate 6. The opposite side is clamped or released by operating the elastic clamps 5. A glass plate 7 is placed on the material plate 1, and a crystal rod 8 is placed on the glass plate 7 for crystal rod bonding.

[0038] Specifically, such as Figure 3 As shown, the elastic clamp 5 includes a handle 5-1, a shaped part 5-5, a guide shaft 5-7, a top block 5-10, and a compression spring 5-11. The handle 5-1 is connected to the elastic clamp base plate 5-3 via a first rotating shaft 5-2, specifically a rotatable connection. A push bearing 5-4 is provided on the side of the handle 5-1 near the shaped part 5-5. The shaped part 5-5 is connected to the elastic clamp base plate 5-3 via a second rotating shaft 5-6, specifically a rotatable connection. It also includes a guide shaft 5-7, on which a guide shaft guide 5-8 is provided. The shaped part 5-5 abuts against the guide shaft guide 5-8, and the guide shaft 5-7 passes through... A spring groove 5-9 is provided, and a top block 5-10 is provided at one end of the guide shaft 5-7 near the reference plate 6, which can be fixedly set; the top block 5-10 is partially placed in the spring groove 5-9, and a compression spring 5-11 is sleeved on the outside of the guide shaft 5-7. The two ends of the compression spring 5-11 are connected to the top block 5-10 and the inner wall of the spring groove 5-9, which can be either abutting or fixedly connected; the irregular part 5-5 has a guide surface 5-5-1 and a guide force-applying end 5-5-2. The guide surface 5-5-1 abuts against the push bearing 5-4, and the guide force-applying end 5-5-2 abuts against the guide shaft guide 5-8. When the push bearing 5-4 moves along the guide surface 5-5-1 to the first point, i.e., the clamping position of the elastic clamp, the compression spring 5-11 resets, causing the top block 5-10 to move towards the reference plate 6. When the push bearing 5-4 moves along the guide surface 5-5-1 to the second point, i.e., the releasing position of the elastic clamp, the force-applying end 5-5-2 of the guide member causes the guide shaft guide member 5-8 to move away from the reference plate 6. The material plate 1 can be quickly clamped or released by operating the handle 5-1.

[0039] like Figure 4As shown, the crystal rod detection and positioning mechanism includes a crystal rod holder assembly 10, a crystal rod holder adjustment assembly 11, an X-ray tube 12, an X-ray tube adjustment assembly 13, a scintillation counter 14, and a rotary encoder 15. The X-ray tube 12 is connected to the X-ray tube adjustment assembly 13. A monochromator can be set up so that X-rays are projected onto a monochromatic crystal wafer through the X-ray tube 12, undergo diffraction filtering once, and then be projected onto the crystal rod 8, thereby improving resolution. The crystal rod holder assembly 10 is connected to the crystal rod holder adjustment assembly 11, which is used to adjust the position of the crystal rod holder assembly 10. The scintillation counter 14 is set opposite to the X-ray tube 12. The angular position is determined by counting the number of electrons by the scintillation counter 14. The process of determining the angular position by counting the number of electrons by the scintillation counter 14 is existing technology and will not be described in detail here. This utility model uses a scintillation counter 14, which has high received signal strength and good signal stability. It can compensate for the intensity attenuation of the X-ray tube 12, indirectly extending the life of the X-ray tube 12 and reducing the cost of use. The rotary encoder 15 is connected to the drive motor of the X-ray tube adjustment assembly 13 via a connecting rod. Specifically, the rotary encoder 15 is synchronized with the drive motor of the X-ray tube adjustment assembly 13 via the connecting rod to provide feedback on the angle value. The power drive elements of the lifting assembly 4, translation assembly 3, crystal rod holder assembly 10, crystal rod holder adjustment assembly 11, and X-ray tube adjustment assembly 13 are connected to the PLC control system. The X-ray tube 12, flash counter 14, and rotary encoder 15 are also connected to the PLC control system, enabling precise displacement of moving components during the bonding process and providing position and angle feedback to the workers.

[0040] like Figure 5As shown, the X-ray tube adjustment assembly 13 includes an X-ray tube connecting plate 13-1. One end of the X-ray tube connecting plate 13-1 is connected to the X-ray tube 12 via a linkage mechanism 13-2, and the other end is connected to the first locking seat 13-4 via a first connecting plate 13-3. Specifically, the first connecting plate 13-3 can be vertically fixedly connected to the X-ray tube connecting plate 13-1. The first locking seat 13-4 has a first positioning steel ball 13-5 and a first deep groove ball bearing 13-6 on opposite sides. The first connecting plate 13-3 is positioned between the first positioning steel ball 13-5 and the first deep groove ball bearing 13-6, clamping and allowing for angular rotation, which is used to compensate for the angular deviation caused by the displacement of the X-ray tube connecting plate 13-1. The bottom of the first mounting base 13-4 is connected to the nut of the first ball screw 13-7. One end of the lead screw of the first ball screw 13-7 is connected to the first stepper motor 13-8, and the other end is connected to the first knob 13-9. The bottom of the first mounting base 13-4 is also connected to the linear guide rail. The X-ray tube connecting plate 13-1 moves along the first ball screw 13-7 via the first mounting base 13-4. This movement can be controlled by the first stepper motor 13-8 connected to the PLC control system, or manually controlled by the first knob 13-9. When manually controlled by the first knob 13-9, the first stepper motor 13-8 is in manual mode under the PLC control system, meaning the first stepper motor 13-8 is disengaged and manually controlled by the first knob 13-9. In actual operation, manual control with the first knob 13-9 is usually used first to find the approximate position, and then the control is switched to the first stepper motor 13-8 for further adjustment.

[0041] The crystal rod holder adjustment assembly 11 includes a crystal rod holder connecting plate 11-1. One end of the crystal rod holder connecting plate 11-1 is connected to the crystal rod holder assembly 10, and the other end is connected to the second locking seat 11-2 through a second connecting plate. Specifically, the second connecting plate can be vertically connected to the crystal rod holder connecting plate 11-1. The second locking seat 11-2 has a second positioning steel ball 11-3 and a second deep groove ball bearing 11-4 on opposite sides. The second connecting plate is disposed between the second positioning steel ball 11-3 and the second deep groove ball bearing 11-4, clamping and allowing for angular rotation, which is used to compensate for the angular deviation caused by the displacement of the crystal rod holder connecting plate 11-1. The bottom of the second locking seat 11-2 is connected to the nut of the second ball screw 11-6. One end of the lead screw of the second ball screw 11-6 is connected to the second stepper motor 11-5, and the other end is connected to the second knob 11-7. The bottom of the second locking seat 11-2 is also connected to the linear guide rail. The crystal rod holder connecting plate 11-1 moves along the second ball screw 11-6 via the second locking seat 11-2. This movement can be controlled by the second stepper motor 11-5 connected to the PLC control system, or manually controlled by the second knob 11-7. When manually controlled by the second knob 11-7, the second stepper motor 11-5 is in manual mode under the PLC control system, i.e., the second stepper motor 11-5 is disengaged from the control system and manually controlled by the second knob 11-7. In actual operation, manual control by the second knob 11-7 is usually used first to find the approximate position, and then the control is switched to the second stepper motor 11-5 for further adjustment.

[0042] To achieve a compact layout of the bonding device, the crystal rod holder adjustment assembly 11 and the X-ray tube adjustment assembly 13 can be arranged close together, specifically as follows: Figure 4 , 5 As shown, the second knob 11-7, the second ball screw 11-6, and the second stepper motor 11-5 are positioned close to the first knob 13-9, the first ball screw 13-7, and the first stepper motor 13-8. At this time, the crystal rod holder connecting plate 11-1 and the X-ray tube connecting plate 13-1 are positioned vertically. The X-ray tube connecting plate 13-1 and the crystal rod holder connecting plate 11-1 are connected to the rotating spindle 19. Figure 7As shown, the rotating spindle 19 includes a second spindle shaft 19-5 connected to the crystal rod holder connecting plate 11-1 and a first spindle shaft 19-1 connected to the X-ray tube connecting plate 13-1. The first spindle shaft 19-1 is connected to the bearing connector 19-2 through the first spindle bearing 19-3, and the second spindle shaft 19-5 is connected to the bearing connector 19-2 through the second spindle bearing 19-4. Specifically, the bearing connector 19-2 is a cylindrical structure, and its upper and lower outer rings are rotatably connected to the first main shaft 19-1 through the first main shaft bearing 19-3. The first main shaft 19-1 can also be a cylindrical structure, which is fitted outside the bearing connector 19-2. The bottom of the first main shaft 19-1 is connected to the X-ray tube connecting plate 13-1. The upper and lower inner rings of the bearing connector 19-2 are rotatably connected to the second main shaft 19-5 through the second main shaft bearing 19-4. The bottom of the second main shaft 19-5 is connected to the crystal rod holder connecting plate 11-1, so that the rotation of the crystal rod holder connecting plate 11-1 and the X-ray tube connecting plate 13-1 does not interfere with each other.

[0043] like Figure 6 As shown, the crystal rod holder assembly 10 includes a holder column 10-2 connected to the crystal rod holder adjustment assembly 11. The bottom of the holder column 10-2 is connected to the holder base plate 10-1, which can be a fixed connection. The holder base plate 10-1 is provided with a vertical plate 10-3, which is connected to a lifting cylinder 10-5. Specifically, an adjustment slide plate 10-4 can be provided between the vertical plate 10-3 and the lifting cylinder 10-5. The adjustment slide plate 10-4 is laterally slidably connected to the vertical plate 10-3. The adjustment slide plate 10-4 is provided with an elongated hole, which is positioned by bolts to achieve lateral adjustment of the position of the lifting cylinder 10-5. The free end of the lifting cylinder 10-5 is connected to the horizontal cylinder 10-6, which can be a fixed connection; the free end of the horizontal cylinder 10-6 is connected to the crystal rod clamping plate 10-7, which is used to position the crystal rod. The clamping plate 10-1 has a crystal rod positioning head 10-8 at the end facing the crystal rod. Specifically, the clamping plate 10-1 has an elongated hole at the corresponding position of the crystal rod positioning head 10-8, and the position of the crystal rod positioning head 10-8 is adjusted by bolts.

[0044] like Figure 1 As shown, the crystal rod detection and positioning mechanism is mounted on the upper platform 16, and the moving platform mechanism is mounted on the lower platform 17. Specifically, the lower platform 17 can be a granite platform to ensure that the linear guide rail can be adjusted to the optimal state. This allows the moving platform mechanism to move horizontally, and when monitored with a dial indicator, the needle remains stationary, improving stability and detection accuracy. The upper platform 16 and the lower platform 17 are connected by a fixed connector 18, which can be a cast iron frame to ensure the stability of the upper and lower platforms and minimize the impact of temperature and humidity changes on accuracy.

[0045] During operation, the material plate 1 is first quickly positioned on the material plate receiving plate 2 using the elastic clamp 5. The PLC controls the translation stepper motor 3-5 and the lifting motor to lift and translate the material plate 1 until it is in the correct position. Then, the glass plate 7 is placed and bonded. Crystal rods or crystal blocks are placed on the glass plate 7. When bonding the crystal rods or crystal blocks, the PLC controls the crystal rod holder assembly 10 to clamp the crystal rods or crystal blocks, and the fixation is completed. The X-ray tube adjustment assembly 13 scans according to the set scanning range and stops at the peak position, and the operator performs the crystal rod bonding operation.

[0046] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any modifications, alterations, substitutions, and variations made by those skilled in the art to the above embodiments are within the scope of the present invention.
