TECHNICAL FIELD

[0001] The present application relates to the technical field of calibration devices, in particular to a laser height measurement calibration device. BACKGROUND

[0002] In the current semiconductor and precision machining industry, as an important equipment for wafer processing, the high precision of the dicing machine is directly related to the accuracy of the dicing depth and the product yield. Especially in the process of high-density and high-integration chips, the control of the gap between the blade and the worktable is extremely strict. Therefore, the industry has begun to introduce laser ranging technology to assist in realizing non-contact accurate height measurement, so as to improve the intelligence and stability of the overall operation of the equipment.

[0003] At present, the existing technology mainly realizes the distance measurement between the main shaft and the worktable by fixed installation of the laser ranging sensor, mainly through software to collect data in real time to construct the height measurement curve. During the process execution, the main shaft gradually approaches the worktable, and the laser sensor reflects the change trend of the distance, and the system judges the height measurement value as the minimum value of the change curve, so as to serve as the depth control basis. The traditional fixed mode generally relies on mechanical fastening modes such as screws and pressing blocks to realize the installation of the laser sensor.

[0004] However, the existing installation structure has the following problems: the assembly process of the laser ranging sensor is complicated, the alignment efficiency is low, and the installation precision is subject to manual operation; special tools are needed for replacement or calibration, the process is complex, and the time-consuming is long. Especially in the multi-round calibration test scene, the frequent disassembly and assembly operation seriously affects the maintenance efficiency and operation cycle control. In view of the above problems, it is urgent to provide a laser ranging sensor installation solution with a more efficient structure, fast assembly and convenient disassembly, so as to improve the practicality and operation efficiency of the overall calibration system. SUMMARY

[0005] The purpose of the present application is to provide a concrete block rapid sampling device, which solves the problems of traditional laser ranging sensor assembly process being complicated, alignment efficiency being low, and installation precision being subject to manual operation; special tools are needed for replacement or calibration, the process is complex, and the time-consuming is long.

[0006] To achieve the above purpose, the present application realizes the following technical scheme: a laser height measurement calibration device, comprising a dicing machine main shaft: one end of the dicing machine main shaft is provided with a cutter head, the cutter head is internally provided with a blade, the lower side of the blade is provided with a worktable, the outer wall of the dicing machine main shaft is fixedly connected with a water spraying frame near the blade side, a laser ranging sensor is arranged near the water spraying frame side, a buffer pad is attached to one side of the outer wall of the laser ranging sensor, an installation frame is fixedly connected to one side of the outer wall of the buffer pad, and a quick assembly component is installed in the installation frame. The quick-release assembly includes a plug and a housing. One side of the outer wall of the plug is fixedly connected to one side of the outer wall of the mounting bracket. The inner wall of the housing is slidably connected to the outer wall of the plug. A limiting rod is fixedly connected to one side of the inner wall of the plug. A limiting block is fixedly connected to one end of the limiting rod. A spring is sleeved on the outer wall of the limiting rod. A sliding block is slidably connected to the outer wall of the limiting rod. A rack plate is fixedly connected to one side of the outer wall of the sliding block. A rotating shaft is rotatably connected to the inner wall of the plug near the rack plate. A gear is fixedly connected to the middle of the outer wall of the rotating shaft. A locking block is fixedly connected to the outer wall of the rotating shaft near the gear. The outer wall of the locking block engages with the inner wall of the housing. The rack plate meshes with the gear teeth. A sleeve is fixedly connected to the inner wall of the housing opposite to the limiting rod. The sleeve is sleeved on one side of the outer wall of the sliding block. One end of the sleeve abuts against one side of the outer wall of the sliding block. A quick-release assembly is installed inside the housing. A fastening assembly is installed inside the sliding block.

[0007] Furthermore, the quick-assembly assembly, through the sliding fit structure between the insert block and the outer shell, combined with the elastic limiting mechanism consisting of a limiting rod, a limiting block, and a spring, and the meshing transmission structure between the sliding block, rack, gear, and rotating shaft, enables the laser rangefinder sensor to be quickly assembled and disassembled without tools. In use, the user pushes the outer shell with external force, causing the sleeve to press against the sliding block and drive the rack and gear to rotate, thereby driving the rotating shaft to engage the locking block, achieving a quick connection between the laser rangefinder sensor and the mounting bracket. After releasing the force, the spring returns to its original position, and the auxiliary structure automatically restores its original state, improving assembly convenience and repeatability accuracy, making it suitable for efficient installation environments requiring rapid calibration.

[0008] Preferably, the fastening assembly includes a sliding plate and a second locking block. Multiple locking blocks are linearly arranged on their outer walls. One side of the outer walls of the multiple locking blocks is fixedly connected to one side of the outer wall of the sliding plate. The outer wall of the sliding plate is slidably connected to the inner wall of the sliding block. The outer walls of the multiple locking blocks are disposed through the interior of the outer shell.

[0009] Furthermore, the fastening assembly, through a sliding plate and multiple linearly distributed locking blocks, forms a multi-point positioning structure. The sliding plate can slide smoothly within the inner wall of the sliding blocks, thereby driving each locking block through the outer shell to form an effective lock. This structure ensures the overall assembly stability of the laser rangefinder sensor while preventing it from loosening or shifting under high-frequency vibration or continuous movement. The distributed limiting of multiple locking blocks enhances the overall structure's resistance to disturbances and provides multi-faceted support for the insertion blocks and the outer shell, improving installation accuracy and structural stability. This design is simple and compact, effectively improving the reliability and safety of the equipment during operation.

[0010] Preferably, a second spring is fixedly connected to one side of the outer wall of the sliding plate, and one end of the second spring is fixedly connected to the inner wall of the sliding block.

[0011] Furthermore, the second spring provides a continuous elastic rebound force by connecting the sliding plate and the inner wall of the sliding block, so that the sliding plate can automatically reset after the external force is lost, thereby driving the second locking block to quickly reset to the initial locking position, ensuring the reusability and structural stability of the quick-installation structure, and effectively improving the operating efficiency and safety performance of the device.

[0012] Preferably, the quick-release assembly includes a wedge and a connecting piece. The outer wall of the wedge is slidably connected to the inside of the housing. One side of the outer wall of the connecting piece is fixedly connected to one side of the outer wall of the wedge. A reset assembly is installed on one side of the outer wall of the connecting piece.

[0013] Furthermore, the quick-release assembly, through the cooperation of the wedge and the connecting piece, allows users to quickly pull the wedge to perform assembly and disassembly operations, making the operation convenient; at the same time, in conjunction with the elastic rebound function of the reset assembly, the wedge can automatically return to its initial position after being released, ensuring accurate structural reset and improving the reusability and operational reliability of the quick-release system.

[0014] Preferably, the reset assembly includes a limiting rod two and a spring three. One end of the limiting rod two is fixedly connected to one side of the outer wall of the connecting piece, one end of the spring three is fixedly connected to the other end of the limiting rod two, and the other end of the spring three is fixedly connected to one side of the inner wall of the outer shell.

[0015] Furthermore, the reset component, through the elastic cooperation of limit rod two and spring three, enables the connecting piece to automatically return to its initial position after the quick-release action is completed, effectively preventing assembly errors or loosening caused by the component not being reset after operation, and improving the ease of operation and safety of use of the quick-release structure.

[0016] Preferably, a limiting shell is fixedly connected to one side of the outer wall of the outer shell, one side of the inner wall of the limiting shell abuts against one side of the outer wall of the laser rangefinder, and a connecting handle is fixedly connected to one side of the outer wall of the connecting piece.

[0017] Furthermore, by fitting and positioning the limiting shell with the laser rangefinder sensor, and with the connecting handle, the operator can quickly install or remove the sensor, while ensuring its stability during high-frequency vibration or movement, effectively preventing displacement deviation and improving ranging accuracy and structural reliability.

[0018] Preferably, a support shell is fixedly connected to one side of the outer wall of the water spray frame, a motor is fixedly connected to one side of the outer wall of the support shell, and a worm gear is fixedly connected to the output end of the motor through the side wall of the support shell.

[0019] Furthermore, the motor drives the worm gear to rotate, thereby adjusting the lead screw and mounting structure inside the support housing. This facilitates fine-tuning of the laser rangefinder in the vertical direction, meeting the height positioning requirements under different processing conditions and enhancing the adaptability and flexibility of the device.

[0020] Preferably, a limiting disk is slidably connected to the inner wall of the support shell, a lead screw is rotatably connected to the lower surface of the limiting disk, a worm wheel is threadedly connected to the outer wall of the lead screw, and the worm wheel meshes with the tooth end of the worm.

[0021] Furthermore, the combination of the lead screw and the limit plate can achieve precise linear movement driven by the motor. The meshing transmission of the worm gear and worm improves the transmission stability and load capacity, making the height adjustment more stable and reliable, and meeting the requirements of high-precision assembly and testing.

[0022] Preferably, the upper side of the worm gear is rotatably connected to the inside of the support shell, and a connecting column is slidably connected inside the support shell.

[0023] Furthermore, the upper side of the worm gear is rotatably connected inside the support shell. Combined with the connecting column structure, it can effectively constrain the vertical movement path of the sensor during transmission, prevent deviation, and improve the overall positioning stability and structural guidance accuracy of the system.

[0024] Preferably, the lower end of the connecting column is fixedly connected to the upper surface of the mounting frame, the lower end of the lead screw is rotatably connected to the second limiting disk, the outer wall of the second limiting disk is slidably connected to the inner wall of the support shell, and the lower surface of the second limiting disk is fixedly connected to the upper end of the connecting column.

[0025] Furthermore, a stable support and limiting connection is formed between the connecting column and the second limiting plate, which can effectively transmit motion to the mounting frame during the rotation of the lead screw, realize the smooth lifting and lowering adjustment of the laser rangefinder, and thus improve the accuracy and efficiency of the calibration device.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention inserts the outer shell onto the outside of the insert block, and then inserts the sleeve on the inner wall of the outer shell onto the outside of the limiting rod. The sleeve pushes the sliding block to compress the spring, which in turn causes the sliding block to drive the rack plate to mesh with the gear. The gear then drives the outer locking block of the rotating shaft to rotate, thereby achieving the effect of quickly locking the locking block into the inner shell. This allows the laser rangefinder sensor to be quickly assembled on one side of the mounting bracket for use, solving the problem of cumbersome installation and use of tools in traditional calibration devices, and thus improving the practicality of the device.

[0027] 2. In this invention, as the sliding block slides, it drives the second locking block to slide on the inner wall of the outer shell. When the second locking block reaches the hole inside the outer shell, the reaction force of the second spring drives the sliding plate to push the second locking block into the inner shell, thereby achieving the effect of further securing the installation of the laser rangefinder sensor. Then, by pressing the connecting handle, the wedge on one side of the connecting piece slides inside the outer shell, thereby pushing the second locking block to retract into the sliding block, thus achieving the effect of quickly disassembling the laser rangefinder sensor. This solves the problem of inconvenient disassembly in traditional calibration devices, which leads to long machine downtime and affects production efficiency, thereby improving the practicality of the device.

[0028] 3. This invention, through the motor driving the worm gear and worm wheel to mesh and rotate, causes the lead screw to drive the limiting disk one to slide within the support shell, thereby achieving the effect of pushing the limiting disk two to slide within the support shell. Simultaneously, the movement of the limiting disk two drives the connecting column to lift and lower the mounting bracket, thus enabling the adjustment of the laser rangefinder sensor's height according to usage requirements. Furthermore, the precise cooperation between the worm wheel and worm gear allows for precise adjustment of the laser rangefinder sensor's height for distance measurement, solving the problem of traditional calibration devices being unable to precisely adjust the height according to usage requirements, thereby improving the device's practicality.

One side of the outer wall of the plug block 9 is fixedly connected to one side of the outer wall of the mounting bracket 6, serving as an installation reference. The inner wall of the housing 34 is slidably connected to the outer wall of the plug block 9, achieving quick insertion through sliding engagement. A limit rod 10 is fixedly connected to one side of the inner wall of the plug block 9, limiting the travel of the sliding block 13. One end of the limit rod 10 is fixedly connected to a limit block 11, used to stop and prevent overtravel. A spring 12 is sleeved on the outer wall of the limit rod 10, providing a restoring force to the sliding block 13. A sliding block 13 is slidably connected to the outer wall of the first 10, and the sliding block 13 is used to drive the movement of the internal structure of the quick-assembly mechanism; a rack plate 14 is fixedly connected to one side of the outer wall of the sliding block 13, and the rack plate 14 is used to drive the rotating shaft 15 to rotate by meshing with the gear 16; a rotating shaft 15 is rotatably connected to the inner wall of the insert 9 near the rack plate 14, and the rotating shaft 15 is used to transmit the rotational force after the gear 16 is meshed; a gear 16 is fixedly connected to the middle of the outer wall of the rotating shaft 15, and the gear 16 and the rack plate 14 achieve meshing transmission; a locking block 17 is fixedly connected to the outer wall of the rotating shaft 15 near the gear 16, and the locking block 17... 7. The outer wall engages with the inner wall of the outer casing 34 to achieve initial engagement and positioning. A sleeve 21 is fixedly connected to the inner wall of the outer casing 34 on the side opposite to the limiting rod 10. The sleeve 21 is fitted onto one side of the outer wall of the sliding block 13 as a sliding guide component. One end of the sleeve 21 abuts against one side of the outer wall of the sliding block 13 to stably support the sliding state. A quick-release assembly is installed inside the outer casing 34 to facilitate sensor disassembly and replacement. A fastening assembly is installed inside the sliding block 13 to enhance connection stability. The fastening assembly includes a sliding plate 18 and a second locking block 19. The outer wall of the second locking block 19 is linear. Multiple locking blocks 19 are provided to achieve multi-point fixing and improve clamping strength; one side of the outer wall of multiple locking blocks 19 is fixedly connected to one side of the outer wall of the sliding plate 18, and synchronously advances and retreats through the linkage of the sliding plate 18; the outer wall of the sliding plate 18 is slidably connected to the inner wall of the sliding block 13, and is used to cooperate with the sliding to realize the internal locking action; the outer walls of multiple locking blocks 19 are installed through the inside of the outer shell 34, and are used to engage and lock with the external structure; one side of the outer wall of the sliding plate 18 is fixedly connected to a spring 20, and one end of the spring 20 is fixedly connected to the inner side wall of the sliding block 13, and is used to provide pre-tightening force for the locking blocks 19.

[0033] Specifically, through the aforementioned structural cooperation, when installing the laser rangefinder sensor 8, the outer casing 34 can be slidably inserted into the insert block 9, and the sliding block 13 is pushed by the sleeve 21, thereby causing the rack plate 14 to mesh with the gear 16. After the rotating shaft 15 rotates, the locking block 17 quickly snaps into the inner wall of the outer casing 34, achieving locking and fixation. After the external force is released, the spring 12 returns to pushing the sliding block 13, completing the automatic reset process. The overall structure realizes the rapid assembly and stable fixation of the laser rangefinder sensor 8, avoiding the problems of needing tools and complicated operations in the traditional assembly process, improving the convenience of use of the device and the efficiency of height measurement and calibration.

[0034] Please see the appendix Figure 1 -Appendix Figure 8 The quick-release assembly includes a wedge 22 and a connecting piece 23. The outer wall of the wedge 22 is slidably connected inside the housing 34 to provide a radial or axial limiting slope during assembly or disassembly, which facilitates fastening or release in conjunction with other locking structures. One side of the outer wall of the connecting piece 23 is fixedly connected to one side of the outer wall of the wedge 22 to drive the wedge 22 to generate effective displacement inside the housing 34 under the action of external force, thereby realizing quick loading and unloading operations. A reset assembly is installed on one side of the outer wall of the connecting piece 23 to automatically spring back after disassembly, ensuring assembly reset accuracy. The reset assembly includes a second limiting rod 24 and a third spring 25. One end of the second limiting rod 24 is fixedly connected to one side of the outer wall of the connecting piece 23 to limit the movement stroke of the connecting piece 23 and prevent it from leaving the working range. One end of the third spring 25 is fixedly connected to the other end of the second limiting rod 24, and the other end is fixedly connected to one side of the inner wall of the outer shell 34 to provide a rebound force. After the connecting handle 35 is released, the wedge block 22 is automatically reset to the initial position, ensuring the reliability of disassembly and assembly and the repeatability of positioning accuracy. A limiting shell 36 is fixedly connected to one side of the outer wall of the outer shell 34. One side of the inner wall of the limiting shell 36 abuts against one side of the outer wall of the laser ranging sensor 8 to realize external protection and position limit of the sensor body, preventing the sensor from loosening or shifting due to vibration during operation. A connecting handle 35 is fixedly connected to one side of the outer wall of the connecting piece 23. The connecting handle 35 is used to manually apply force to control the movement state of the wedge block 22, making disassembly or assembly operations more convenient and improving the human-machine operation friendliness of the overall device.

[0035] Specifically, when the laser rangefinder sensor 8 needs to be disassembled, the operator only needs to press the connecting handle 35 to slide the connecting piece 23 and the wedge block 22, and cooperate with the limiting shell 36 to loosen the locking area, so that the sensor can be released quickly. After the operation is completed, the spring 3 25 drives the wedge block 22 to automatically reset through the limiting rod 2 24, and completes the structural closure and locking. The overall structure is simple and compact, which effectively improves the quick disassembly efficiency and positioning reliability of the laser rangefinder sensor 8.

[0036] Please see the appendix Figure 1 -Appendix Figure 8A support shell 26 is fixedly connected to one side of the outer wall of the water spray frame 5. The support shell 26 provides structural support and stable installation space for the transmission components, motor 27 and other components installed on it. At the same time, it serves as an external protective structure to protect the internal components from external environmental interference. A motor 27 is fixedly connected to one side of the outer wall of the support shell 26. The motor 27 serves as a power source. Its output end passes through the side wall of the support shell 26 and is fixedly connected to a worm gear 28. It is used to transmit rotational power to the internal worm wheel 31 mechanism, thereby realizing the lifting and lowering control of the lower connecting structure. A limit plate 30 is slidably connected to the inner wall of the support shell 26. A lead screw 29 is rotatably connected to the lower surface of the limit plate 30. It provides sliding guidance and rotational support during the transmission process, ensuring that the lead screw 29 runs smoothly during the lifting and lowering process. A worm gear 31 is threaded onto the outer wall of the lead screw 29. The worm gear 31 meshes with the toothed end of the worm 28, converting the rotational motion of the motor 27 into the helical lifting motion of the lead screw 29, thus achieving the height adjustment function of the support component of the laser rangefinder sensor 8. The upper side of the worm gear 31 is rotatably connected inside the support shell 26, providing stable axial support for its rotation. A connecting column 33 is slidably connected inside the support shell 26, with its lower end fixedly connected to the upper surface of the mounting frame 6, serving as a force transmission and linkage support, allowing the mounting frame 6 to move up and down with the lead screw 29, thereby achieving vertical displacement control of the laser rangefinder sensor 8. A limit plate 32 is rotatably connected to the lower end of the lead screw 29. The outer wall of the limit plate 32 is slidably connected to the inner wall of the support shell 26, limiting the movement boundary of the lead screw 29 and ensuring the reliable operation of the overall structure. The lower surface of the limit plate 32 is fixedly connected to the upper end of the connecting column 33, further enhancing the structural coupling stability between the connecting column 33 and the lead screw 29.

[0037] Specifically, through the synergistic effect of the above structures, the worm gear 28 is driven by the motor 27 to rotate, and the worm wheel 31 is linked to the lead screw 29 to rotate, thereby driving the connecting column 33 and the mounting bracket 6 to slide up and down in the support shell 26, so that the height of the laser range sensor 8 can be adjusted to meet the alignment requirements under different working conditions, and improve the adjustment accuracy and application flexibility of the device.

[0038] Working principle: When using this laser height measurement calibration device, during installation, the laser range sensor 8 is placed against the outside of the buffer pad 7, and then the limiting shell 36 is engaged with the outside of the laser range sensor 8. After the outer shell 34 is inserted into the outer wall of the insert block 9, the sleeve 21 inside the outer shell 34 will slide around the outside of the limiting rod 10, thereby achieving the effect of limiting the sliding while pushing the sliding block 13 to squeeze the spring 12. As the sliding block 13 slides, it drives the second locking block 19 to engage in the mounting groove inside the outer shell 34. At the same time, the movement of the sliding block 13 can drive the rack plate 14 to mesh with the gear 16. Through the rotation of the gear 16, the locking block 17 is engaged inside the limiting rod 24, thereby achieving the effect of quick and efficient installation of the laser range sensor 8. When it is necessary to disassemble the laser rangefinder sensor 8, by pressing the connecting handle 35, the connecting piece 23 drives the wedge block 22 and the limiting rod 24 to move synchronously. At this time, the wedge block 22 slides inside the outer shell 34, which can push the second locking block 19 into the sliding block 13. After the spring 12 restores the stress, it will push the sliding block 13, which will cause the sleeve 21 to drive the outer shell 34 to quickly disassemble from the outside of the insert block 9, thereby achieving the effect of quickly disassembling the laser rangefinder sensor 8. When the installation height of the laser rangefinder sensor 8 needs to be adjusted, the motor 27 is started, which drives the worm gear 28 to mesh and rotate with the worm wheel 31. At this time, through the transmission of the worm wheel 31, the lead screw 29 drives the limiting disk 30 to slide within the support shell 26. Then, the lead screw 29 pushes the connecting column 33 on the lower side of the limiting disk 32 to move, thereby realizing the effect of driving the mounting bracket 6 to adjust the height of the laser rangefinder sensor 8 according to the usage requirements. When the equipment begins height measurement, it controls the rotation of the spindle 1 of the dicing machine. This rotation drives the cutter head 2 and the blade 3 to rotate at high speed. The equipment controls the blade 3 to gradually contact the working disc 4. When the working disc 4 contacts the blade 3, the equipment records and displays the height measurement position. Then, the equipment controls the spindle 1 of the dicing machine to lift up at high speed. At the start of height measurement, the software reads the current distance between the laser rangefinder 8 and the working disc 4 in real time, records and plots the height measurement curve. The minimum value of the curve is the height measurement value currently measured by the laser rangefinder 8.
