Description

Technical Field

[0001] This utility model relates to the field of groove bar processing technology, specifically to a groove bar grooving device for a quartz longboat. Background Technology

[0002] Quartz boats are essential tools in diffusion processes. Whether in semiconductor device diffusion or solar energy diffusion, quartz devices are extensively used as carriers. Quartz boats are heat-resistant, do not deform, do not contaminate devices, and are reusable. Especially in recent years, due to the rapid development of the solar energy industry, the use of quartz boats has become increasingly widespread, playing a significant role in the photovoltaic industry. Structurally, a quartz boat is essentially a boat-like carrier composed of multiple slotted quartz square rods and a pair of quartz side caps. Multiple solar cells can be inserted into the slots for diffusion processing. Therefore, slotting the quartz square rods is undoubtedly the most crucial step in quartz boat processing, especially for long quartz boats. Because the square rods are quite long (greater than 1400mm), positioning and fixing them during slotting is a challenge, directly affecting the quality and precision of the slotted rods. The main body of the slotting device for the square rods is a cutting tool that can translate along the X-axis, 1 / 2-axis, and 2 / 3-axis. Currently, in CNC machine tools with coordinate axes, square bars are generally fixed directly onto the worktable of the CNC machine tool with a 90° V-groove before grooving. After the square bar is embedded in the V-groove, stop blocks are inserted at both ends of the V-groove to prevent the square bar from moving left and right. However, in actual use, it has been found that this fixing method causes the square bar to vibrate slightly up and down during the cutting process. This can result in uneven grooving or even breakage of the square bar. In order to reduce the temperature at the cutting point during grooving, coolant needs to be continuously sprayed onto the cutting position. The main component of the coolant is water. After the square bar is grooved, it is in a relatively humid environment. The force between water molecules will tightly bind the 90° V-groove to the two sides of the square bar embedded in it. Too many hydrogen bonds result in strong bonding force, making it difficult to remove the square bar directly from the grooving device after grooving. Therefore, there is an urgent need for a quartz longboat-type grooving device for square bars to overcome the many problems mentioned above in the grooving process.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN210061633U discloses a grooving device for a quartz longboat, comprising a three-axis CNC machine tool body. A tool set is mounted on the beam frame of the three-axis CNC machine tool body. The tool set includes a blade shaft, a blade, and a drive motor. A graphite plate is provided on the table of the three-axis CNC machine tool body. The upper surface of the graphite plate has several parallel "V"-shaped grooves. The bottom of the "V"-shaped groove is a square groove structure, and a "V"-shaped positioning groove is provided at the center of the bottom of the square groove. The tool set is connected to a cooling device.

[0004] While the aforementioned existing technical solutions make it less prone to damage during the grooving process of quartz square bars and allow for simultaneous grooving of multiple quartz square bars with high grooving efficiency, they require workers to pour liquid wax into each quartz square bar individually to fill the gaps for positioning. Furthermore, disassembly requires workers to heat and melt the liquid wax, rinse it, and remove the liquid wax from the groove gaps, which is cumbersome and time-consuming, thus reducing work efficiency. Additionally, liquid wax undergoes thermal expansion and contraction during use; after cooling and solidification, its volume shrinks, making it difficult to ensure uniform cooling and forming speed across different parts. This easily leads to localized solidification of the liquefied wax, with the uncured wax being squeezed to the other end, causing one end of the quartz square bar to tilt upwards and the other downwards. Moreover, the fixed V-groove dimensions prevent the rapid replacement of different molds to position quartz bars of different sizes. Utility Model Content

[0005] The purpose of this utility model is to provide a grooving device for quartz longboats, to solve the problems mentioned in the background art. In this device, when positioning quartz square rods, workers need to pour liquid wax one by one to fill the gaps for positioning. During disassembly, workers need to heat and melt the liquid wax, rinse it, and remove the liquid wax from the groove gaps. This is cumbersome and time-consuming, reducing work efficiency. Furthermore, liquid wax expands and contracts with temperature changes; after cooling and solidifying, its volume shrinks, making it difficult to ensure uniform cooling and forming speed across different parts. This easily leads to localized solidification of the liquefied wax, with the uncured wax being squeezed to the other end, causing the quartz square rod to tilt upwards at one end and be pulled and shifted by the solidified and contracted liquefied wax at the other end. Additionally, the fixed V-groove size makes it difficult to quickly replace different molds to position quartz rods of different sizes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0023] A grooving device for a quartz longboat includes a three-axis CNC machine tool body 1. A cutting machine body 2 is mounted on the top of the three-axis CNC machine tool body 1. The cutting machine body 2 includes a blade shaft, a blade 4, and a drive motor. A cooling device is mounted on one side of the cutting machine body 2, and a coolant nozzle 3 is mounted on the cooling device. Multiple sets of overlapping columns 5 are arranged on the top of the inner side of the three-axis CNC machine tool body 1. The top of the overlapping column 5 has a groove, and a placement column 6 is slidably connected to the inner side of the groove. A quick-connect positioning mechanism is mounted on the placement column 6. The quick-connect positioning mechanism includes a quick-connect component and a clamping positioning component. The quick-connect component is used to replace the clamping positioning component. The positioning component is used to position the slotted bar. During use, the clamping and positioning component can be replaced by a quick-connect component. The clamping and positioning component positions the slotted bar. The structure is simple and easy to operate. The first clamping plate 21 and the second clamping plate 25 of the corresponding size can be flexibly replaced according to actual needs to process quartz bars of different sizes and models. The quartz bars can be quickly picked up and put away during processing. When clamping, the spring pads 26 on both sides can deform to a certain extent to tightly press the surface of the quartz bar. The rubber properties of the spring pads 26 can also absorb the vibration that occurs during cutting, further ensuring the cutting accuracy, improving work efficiency and increasing the practicality and flexibility of the device.

[0024] In this embodiment, as Figure 1 and Figure 3As shown, the clamping and positioning assembly includes a connecting plate installed on the other side of the outer wall of the placement column 6. A bracket 20 is installed inside the connecting plate. A first clamping plate 21 is installed on one side of the bracket 20. An adjusting cylinder 24 is installed at the top of the bracket 20. A threaded rod 22 is rotatably connected to the inner side of the adjusting cylinder 24. An adjusting plate 23 is threadedly connected to the outer side of the threaded rod 22. The adjusting plate 23 and the inner side of the adjusting cylinder 24 are slidably connected. A second clamping plate 25 is installed at the other end of the adjusting plate 23. V-grooves are formed on the opposing surfaces of the first clamping plate 21 and the second clamping plate 25. A spring-loaded pad 26, made of rubber, is embedded in the inner wall of the V-groove. A second clamping plate 25 is installed at the top of the adjusting cylinder 24. A motor 27 is used. The drive end of the first motor 27 extends to the inside of the adjusting cylinder 24 and is fixedly connected to one end of the threaded rod 22. First, the two ends of each set of quartz rods are placed on the surface of the spring pads 26 on the first clamping plate 21. Then, the first motor 27 is started to drive the threaded rod 22 to rotate, so that the adjusting plate 23 drives the second clamping plate 25 to move down. The surfaces of the two sets of spring pads 26 begin to fit together. As the second clamping plate 25 moves, the two sets of spring pads 26 undergo a certain degree of retraction deformation and tightly fit the surface of the quartz rod to complete the positioning and clamping operation. After clamping is completed, the main body of the cutting machine 2 can be started to perform grooving processing on the surface of the quartz rod according to the actual grooving position.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the quick-connect assembly includes an operating rod 7 slidably connected inside the placement column 6. A protective cover 8 is installed at the top end of the placement column 6. A first spring 9 is installed inside the protective cover 8 at the top of the placement column 6. A sliding plate 10 is installed on one side of the first spring 9. One side of the sliding plate 10 is rotatably connected to the operating rod 7. The sliding plate 10 is slidably connected to the inside of the protective cover 8. A pull ring 11 is rotatably connected to the top of the operating rod 7. A return groove is opened at the bottom end of the placement column 6. A locking block 12 is installed at the end of the operating rod 7 extending into the return groove. A cross groove is opened on one side of the groove inside the overlapping column 5. The longitudinal and transverse ports of the cross groove are slidably connected to the locking block 12. The diameter of the operating rod 7 is larger than the width of the longitudinal and transverse ports of the cross groove. The operating rod 7 and the cross groove are connected in a slidable manner. The center of the slot is a sliding connection. Then, when the workers are assembling the first clamping plate 21 and the second clamping plate 25 of different sizes, they can insert the placement column 6 on the bracket 20 into the groove on the overlapping column 5. Then, they can press down the operating rod 7 to make the sliding plate 10 squeeze the first spring 9 inside the protective cover 8. The protective cover 8 can prevent the cutting debris from entering the first spring 9. The locking block 12 enters the installation slot from the inside of the return slot along the cross slot port. When the locking block 12 passes the extension block 13, the two inclined surfaces abut against each other. The extension block 13 is forced to squeeze the second spring to retract. As it continues to move down, the inclined surface on the locking block 12 contacts the slope of the dial plate 14, causing it to drive the torsion spring 15 to retract. At this time, the insert plate 16 has been inserted into the slot. The movable seat 19 and the fixed plate 17 will also cooperate with the synchronous plate 18 to squeeze the third spring to retract.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the lap post 5 has an installation groove on one side of the cross groove. Both ends of the inner wall of the installation groove have extension grooves. A second spring is installed on one side of the inner wall of the extension groove, and an extension block 13 is installed on the other end of the second spring. The opposite ends of the locking block 12 and the two sets of extension blocks 13 have inclined surfaces for close contact. The bottom end of the extension block 13 has a torsion groove. A connecting rod is rotatably connected to the inside of the torsion groove. A lever 14 is installed on the outside of the connecting rod. A slope corresponding to the inclined surface is opened on one side of the lever 14. A torsion spring 15 is installed between the connecting rod and the torsion groove. Both ends of the top of the locking block 12 have abutment grooves. The lever 14 is slidably connected to the inside of the abutment groove. Furthermore, after the locking block 12 moves away from the extension block 13 and the torsion spring 15 drives the lever 14 to reset, the pull ring 11 can be released, allowing the locking block 12 to be lifted. At this time, the lever 14 is inserted into the inside of the abutment groove to lock the required clamping and positioning components.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, insert plates 16 are installed at both ends of the bottom of the locking block 12, and third springs are installed at both ends of the bottom of the inner wall of the mounting groove. A fixing plate 17 is installed at the other end of the third spring. Synchronous plates 18 that are slidably connected to the mounting groove are installed at both ends of the fixing plate 17. A movable seat 19 is rotatably connected to the top of the fixing plate 17. Slots that are slidably connected to the insert plates 16 are opened at both ends of the top of the movable seat 19. Furthermore, when the operator needs to disassemble the installed clamping and positioning components for replacement or maintenance, the pull ring 11 can be fastened again to drive the locking block 12 to move down. Then, the operating rod 7 is twisted to rotate the movable seat 19 in conjunction with the insert plates 16 and the slots. After the locking block 12 is rotated to the longitudinal direction, the operating rod 7 can be pulled back to allow the locking block 12 to retract along the longitudinal port of the cross groove to the inside of the return groove. At this time, the placement column 6 and the bracket 20 can be pulled up together to complete the separation.

[0028] The implementation principle of the grooving device for a quartz longboat according to this application embodiment is as follows: The two ends of each set of quartz rods are placed on the surface of the spring pads 26 on the first clamping plate 21. Then, the first motor 27 is directly started to drive the threaded rod 22 to rotate, causing the adjusting plate 23 to move the second clamping plate 25 downwards. The surfaces of the two sets of spring pads 26 begin to adhere. As the second clamping plate 25 moves, the two sets of spring pads 26 undergo a certain degree of retraction deformation and tightly adhere to the surface of the quartz rod, completing the positioning and clamping operation. After clamping, the cutting machine body 2 can be started to groove the surface of the quartz rod according to the actual grooving position. When assembling the first clamping plate 21 and the second clamping plate 25 of different sizes, the operator can insert the placement column 6 on the bracket 20 into the groove on the overlapping column 5. Then, the operating rod 7 is pressed down to cause the sliding plate 10 to squeeze the first spring 9 inside the protective cover 8. The protective cover 8 can prevent cutting debris from entering the first spring 9. The locking block 12 enters the installation groove from the inside of the return groove along the cross groove port. When block 12 passes extension block 13, their inclined surfaces abut against each other, forcing extension block 13 to compress the second spring and retract. As it continues to move downward, the inclined surface of the locking block 12 contacts the slope of the dial plate 14, causing it to drive the torsion spring 15 to retract. At this time, the insert plate 16 has been inserted into the slot, and the movable seat 19 and the fixed plate 17 will also cooperate with the synchronous plate 18 to compress the third spring and retract until the locking block 12 moves away from extension block 13, allowing the torsion spring 15 to drive the dial plate 14 to reset. Then the pull ring 11 can be released, allowing the locking block 12 to be lifted. At this time, the dial plate 14 will then... The clamping and positioning components are locked inside the abutment groove. When the operator needs to remove the installed clamping and positioning components for replacement or maintenance, the pull ring 11 can be fastened again to move the clamping block 12 down. Then, the operating lever 7 is twisted to rotate the movable seat 19 in conjunction with the insert plate 16 and the slot. After the clamping block 12 is rotated to the longitudinal direction, the operating lever 7 can be pulled back to allow the clamping block 12 to retract along the longitudinal port of the cross groove to the inside of the return groove. At this time, the placement column 6 and the bracket 20 can be pulled up together to complete the separation.

[0029] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
