Description

Technical Field

[0001] This invention relates to the field of quartz product processing equipment, and in particular to an automatic quartz rod cutting device. Background Technology

[0002] Quartz materials possess excellent high-temperature resistance, chemical inertness, and structural stability, occupying an irreplaceable position in technologies such as semiconductors, photovoltaics, and precision chemicals. They can maintain morphological stability under extreme high-temperature and high-pressure environments, providing precise and controllable operating conditions for various core processes, making them a key fundamental material for ensuring the quality of high-end manufacturing.

[0003] Quartz boats, as a typical application of quartz materials, are core load-bearing and transport components in processes such as semiconductor wafer annealing, photovoltaic silicon wafer diffusion, and chemical raw material purification. They not only need to provide a high-purity support environment for the workpiece being processed to avoid process contamination, but also require precise structural design to ensure the positional stability of the workpiece during heat treatment, directly affecting the yield and performance of the final product. In the conventional manufacturing process of quartz boats, the quartz groove bar is a core component. The processing of this component requires first cutting long quartz bars into short bars that meet specifications, and then forming the final structure through subsequent grooving processes. Therefore, the cutting accuracy and integrity of the quartz bars are the primary factors determining the manufacturing quality of the quartz boat.

[0004] Currently, quartz rod cutting operations require manual assistance for feeding, positioning, and clamping the quartz rods, resulting in high labor intensity, low production efficiency, and low positioning accuracy. Furthermore, the quartz rods are highly brittle, demanding high stability during the cutting process and uniform clamping. Improper clamping or cutting impacts can easily lead to chipping, cracking, or even complete breakage of the quartz rods. Therefore, further improvements to the cutting equipment are necessary. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic quartz rod cutting device that improves automation, precisely controls the uniformity of clamping force and cutting stability, reduces defects such as chipping and breakage, and increases product qualification rate.

[0007] The feeding mechanism includes a bracket with a groove for receiving quartz rods.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0039] In the description of this invention, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates at least two.

[0040] In the description of this invention, references to "one embodiment" or "some embodiments" mean that one or more embodiments of the invention include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "one embodiment," "some embodiments," "other embodiments," "and other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0041] This invention provides an automatic quartz rod cutting device for cutting long quartz rods into short quartz rods of the required length. It achieves automated operation and precisely controls clamping uniformity and cutting stability, thereby improving product yield. (Refer to...) Figure 1 The quartz rod automatic cutting equipment 100 includes a frame 10 and a feeding mechanism 20, a pushing mechanism 30, a clamping mechanism 40 and a cutting mechanism 50 disposed on the frame 10.

[0042] Reference Figure 2 The feeding mechanism 20 includes a bracket 24, on which a groove 241 for receiving quartz rods is provided. The groove 241 extends along a first direction X.

[0043] The pushing mechanism 30 is located on the side of the bracket 24 and is used to push the quartz rod in the slot 241 toward the clamping mechanism 40.

[0044] Reference Figure 7 and Figure 8 The clamping mechanism 40 includes two sets of clamping components 41 spaced apart, forming a cutting space 42 between the two sets of clamping components 41. Each set of clamping components 41 includes two clamping blocks 45 arranged opposite to each other, a clamping drive unit 43 for driving the two clamping blocks 45 to move, and a damping buffer 44 and a pressure sensor 46 sequentially disposed between the clamping drive unit 43 and each clamping block 45. The pressure sensor 46 is used to detect the clamping force applied by the corresponding clamping block 45 in real time. The two clamping blocks 45 are arranged opposite to each other in a second direction Y, which is perpendicular to the first direction X.

[0045] Reference Figure 7 and Figure 10 The cutting mechanism 50 includes a cutting drive assembly and a cutting wheel 57. The cutting drive assembly is located on the side of the clamping mechanism 40. The cutting wheel 57 is connected to the output shaft of the cutting drive assembly, and the plane of the cutting wheel 57 passes through the cutting space 42.

[0046] During the operation of the aforementioned automatic quartz rod cutting equipment, after the pushing mechanism 30 pushes the quartz rod in the slot 241 to the set position along the first direction X, the clamping drive units 43 in the two sets of clamping assemblies 41 respectively drive the corresponding two clamping blocks 45 to move towards each other at a first speed; when the clamping force of the four clamping blocks 45 in the two sets of clamping assemblies 41 reaches the pre-clamping force value and the difference in clamping force within the two sets of clamping assemblies 41 does not exceed the first difference, the clamping drive units 43 in the two sets of clamping assemblies 41 respectively drive the corresponding two clamping blocks 45 to move towards each other at a second speed; when the clamping force of the four clamping blocks 45 in the two sets of clamping assemblies 41 is within the reference clamping force range, the difference in clamping force within the two sets of clamping assemblies 41 does not exceed the second difference and the difference in clamping force between the two sets of clamping assemblies 41 does not exceed the third difference, the clamping drive unit 43 stops driving, and the cutting drive assembly drives the cutting wheel 57 into the cutting space 42 to cut the quartz rod.

[0047] The intra-group clamping force difference of each clamping assembly is the absolute value of the difference in clamping forces between the corresponding two clamping blocks. The inter-group clamping force difference of two clamping assemblies is the absolute value of the difference in the average clamping forces of the two clamping assemblies. Specifically, if the clamping forces of the two clamping blocks in the first clamping assembly are F11 and F12, and the clamping forces of the two clamping blocks in the second clamping assembly are F21 and F22, then the intra-group clamping force difference of the first clamping assembly is... The difference in clamping force within the second set of clamping components is... The difference in clamping force between the two sets of clamping components is .

[0048] The clamping process described above is divided into two stages: pre-clamping and fine clamping. First, the quartz rod is quickly brought to the pre-clamping state at a first speed to shorten the overall clamping time. Then, the clamping force is finely adjusted at a second speed to ensure that the clamping force falls precisely within the reference range, avoiding overshoot or undershoot. The judgment is based on the clamping force difference within and between groups to ensure that the quartz rod is subjected to uniform force in the circumferential and axial directions, preventing local stress concentration that could lead to microcracks or deformation, and improving clamping uniformity and cutting stability.

[0049] It should be understood that the parameters mentioned above, such as the first speed, pre-clamping force value, first difference, second speed, reference clamping force range, second difference, and third difference, can be reasonably set according to actual conditions. In some preferred embodiments, the first speed is greater than the second speed, the reference clamping force range has a lower limit value and an upper limit value of the reference clamping force, and the pre-clamping force value is 20% to 30% of the lower limit value of the reference clamping force.

[0050] The automatic quartz rod cutting equipment of this invention enables automated operation, significantly reducing labor intensity, shortening the time for quartz rod loading and positioning, and improving production efficiency to meet large-scale demands. The clamping mechanism 40, through real-time monitoring by the pressure sensor 46 and adjustment by the damping buffer 44, combined with a staged clamping control strategy and control of clamping force differences within and between groups, precisely controls the uniformity of clamping force, preventing brittle quartz rods from cracking due to excessive local pressure or loosening and shifting during clamping. Once the clamping force reaches the target and stabilizes, the cutting mechanism 50 drives the cutting wheel 57 into the cutting space for cutting, ensuring cutting accuracy and consistency. The overall coordinated operation of the equipment not only solves the accuracy deviation problem of manual operation and reduces material waste, but also reduces defects such as chipping and breakage, improving product qualification rate and providing a stable and reliable pre-production guarantee for quartz boat manufacturing.

[0051] Further, after cutting is completed, the cutting drive assembly drives the cutting wheel 57 to reset. When the cutting wheel 57 is reset, the clamping drive units 43 in the two sets of clamping assemblies 41 drive the corresponding two clamping blocks 45 to move in opposite directions at a third speed. When the clamping force of all four clamping blocks 45 in the two sets of clamping assemblies 41 is lower than the transition force value and the difference in clamping force within the two sets of clamping assemblies 41 does not exceed the third difference value, the clamping drive units 43 in the two sets of clamping assemblies 41 drive the corresponding two clamping blocks 45 to move in opposite directions at a fourth speed until all four clamping blocks are reset. The parameters such as the third speed, transition force value, third difference value, and fourth speed can be reasonably set according to actual conditions. In some preferred embodiments, the third speed is less than the fourth speed, and the transition force value is 20% to 30% of the lower limit of the reference clamping force.

[0052] After cutting, a segmented force release strategy is adopted. First, the clamping stress is released smoothly at a slower third speed to prevent the brittle quartz rod from cracking at the cut. After confirming that all clamping forces and force differences meet the standards, the speed is switched to a faster fourth speed for rapid reset. The entire process significantly shortens non-processing time and improves equipment cycle time while ensuring that the cut workpiece remains intact and preventing the rod from rolling due to asynchronous release. This forms a safe, stable, and efficient complete clamping closed loop.

[0053] See also Figures 2 to 4 The feeding mechanism 20 includes side plates 21, guide plates 22, guide frames 23, and brackets 24. There are two side plates 21, which are arranged opposite to each other. The guide plates 22 are inclinedly arranged between the two side plates 21. There are two guide frames 23, which are symmetrically arranged at both ends of the lower side of the guide plates 22. The brackets 24 are arranged along the first direction X on the discharge side of the guide frames 23.

[0054] During the feeding process, long quartz rods enter from the higher side of the guide plate 22. Multiple long quartz rods can be temporarily stored on the guide plate 22. Under gravity, the lowest long quartz rod enters between the two guide frames 23, and then slides down into the tray 241 after being guided by the guide frames 23. The guide frames 23 on both sides are inclined, and the higher and lower ends of each guide frame 23 are arc-shaped structures. The higher end of the guide frame 23 connects to the lower side of the guide plate 22, and the lower end of the guide frame 23 connects to the tray 241. Guide grooves are formed on the inner sides of the two guide frames 23. When a long quartz rod enters between the two guide frames 23, both ends of the long quartz rod are respectively located in the guide grooves of the two guide frames 23. The guide grooves guide the long quartz rod to automatically slide down and align, achieving automatic feeding.

[0055] In some preferred embodiments, a material control area is formed between the guide plate 22 and the guide frame 23. A material control block 25 and a material control cylinder 26 are provided in the material control area. The material control cylinder 26 is arranged along the second direction Y, and the material control block 25 is connected to the piston rod of the material control cylinder 26. The end of the material control block 25 away from the material control cylinder 26 has a slope 251 facing the material control area. Further, a baffle 211 is provided on the side plate 21 corresponding to the material control area, and the baffle 211 is perpendicular to the second direction Y.

[0056] In application, multiple long quartz rods are temporarily stored on the guide plate 22. The material control block 25 abuts against the baffle 211, which can limit the multiple long quartz rods and prevent them from slipping. After the long quartz rods in the tray 241 are cut, the material control cylinder 26 can drive the material control block 25 to move backward along the second direction Y, so that a gap is formed between the material control block 25 and the baffle 211 for a single long quartz rod to pass through. After the bottom long quartz rod passes through the gap, the material control cylinder 26 drives the material control block 25 to move forward along the second direction Y, so that the material control block 25 abuts against the baffle 211, thereby limiting the remaining long quartz rods. The inclined surface 251 on the material control block 25 can play a guiding role, making it convenient for the bottom long quartz rod to slide down automatically.

[0057] Reference Figure 3 The feeding mechanism 20 also includes a push cylinder 27, which is located on the side of the bracket 24 along the second direction Y. The piston rod of the push cylinder 27 is connected to the bracket 24. The push cylinder 27 can drive the bracket 24 to move along the second direction Y, so that the bracket 24 can better receive the long quartz rod falling from the guide frame 23 and match the pusher 34 in the pusher mechanism 30.

[0058] Furthermore, a bracket slide rail 28 is provided on the frame 10 along the second direction Y, and a bracket slider 29 is provided at the bottom of the bracket 24. The bracket slider 29 is movably mounted on the bracket slide rail 28. The bracket slider 29 cooperates with the bracket slide rail 28 to ensure the smoothness and reliability of the bracket 24 when it moves along the second direction Y. The bracket slider 29 and the bracket slide rail 28 can adopt existing linear slide rail module products, the structure and working principle of which are existing technologies and will not be described in detail here.

[0059] Reference Figure 5 and Figure 6 The pushing mechanism 30 includes a support frame 31, a first moving module 32, a pushing frame 33, and a pushing component 34. The support frame 31 is disposed on the side of the bracket 24 along the first direction X. The first moving module 32 is disposed on the support frame 31. The pushing frame 33 is movably disposed on the first moving module 32 along the first direction X. The pushing component 34 is disposed on the pushing frame 33 and is aligned with the tray 241. The pushing component 34 can be a hydraulic damper product from the prior art, such as an Airtac ACA series hydraulic damper.

[0060] Initially, the pusher 34 is located at the end of the bracket 24 furthest from the cutting position. Driven by the first moving module 32, the pusher 34 can advance the long quartz rod 200 in the slot 241 along the first direction X towards the cutting position, ensuring the smoothness of the long quartz rod 200's movement. After the long quartz rod in the slot 241 is cut, the first moving module 32 moves the pusher 34 back to the initial position. After the next long quartz rod enters the slot 241, the first moving module 32 then drives the pusher 34 to push the rod towards the cutting position.

[0061] Reference Figure 5 and Figure 6In some embodiments, the first moving module 32 includes a horizontal rail 321, a rack 322, a pusher slider 323, a mounting plate 324, a pusher motor 325, and a gear 326. The horizontal rail 321 and the rack 322 are respectively disposed on the support frame 31 along the first direction X. The pusher slider 323 is movably disposed on the horizontal rail 321, and the mounting plate 324 is fixed on the pusher slider 323. The pusher motor 325 is disposed on the mounting plate 324, and the pusher motor 325 drives the gear 326, and the gear 326 meshes with the rack 322. The pusher frame 33 is fixed on the mounting plate 324. The pusher motor 325 drives the gear 326 to rotate. Since the gear 326 meshes with the rack 322 and the pusher slider 323 engages with the horizontal rail 321, the rotation of the gear 326 drives the pusher slider 323 and the mounting plate 324 to move along the first direction X, thereby driving the pusher component 34 to move along the first direction X, and thus pushing the long quartz rod 200 in the slot 241 towards the cutting position. However, the present invention is not limited to this. In other embodiments, the first moving module can also use other suitable products that can achieve precise control of the pushing process.

[0062] Reference Figure 7 and Figure 10 The cutting drive assembly includes a cylinder base 51, a first hinge shaft 501, a cutting cylinder 52, a mounting column 53, a connecting handle 54, a second hinge shaft 502, a third hinge shaft 503, a connecting frame 55, and a cutting motor 56. The bottom of the cutting cylinder 52 is hinged to the cylinder base 51 via the first hinge shaft 501. The mounting column 53 is located on the side of the cylinder base 51. The piston rod end of the cutting cylinder 52 is hinged to one end of the connecting handle 54 via the second hinge shaft 502, and the other end of the connecting handle 54 is hinged to the mounting column 53 via the third hinge shaft 503. The connecting frame 55 is fixedly connected to the connecting handle 54. The cutting motor 56 is mounted on the connecting frame 55. The cutting wheel 57 is connected to the output shaft of the cutting motor 56, and the plane of the cutting wheel 57 passes through the cutting space 42. The cutting cylinder 52 and the connecting handle 54 form a crank-connecting rod structure through the first hinge shaft 501, the second hinge shaft 502, and the third hinge shaft 503. The crank-connecting rod structure of the cutting mechanism 50 transforms linear drive into smooth arc-shaped oscillating feed of the cutting wheel 57, greatly reducing the instantaneous impact and vibration on the workpiece during initial contact and continuous feed.

[0063] Reference Figure 10 Initially, the piston rod of the cutting cylinder 52 is in the retracted state, and the cutting wheel 57 is in the first position. (Refer to...) Figure 11During the cutting operation, the piston rod of the cutting cylinder 52 extends, and simultaneously, the cutting cylinder 52 rotates clockwise around the first hinge axis 501, driving the connecting handle 54 to rotate clockwise around the third hinge axis 503. The connecting frame 55, the cutting motor 56, and the cutting wheel 57 rotate synchronously with the connecting handle 54, causing the cutting wheel 57 to move to the second position and enter the cutting space 42. At this point, the cutting motor 56 drives the cutting wheel 57 to rotate at high speed, thereby cutting the long quartz rod. The movement of the cutting wheel 57 from the first position to the second position can be considered as the process of the cutting wheel 57 rotating clockwise around the third hinge axis 503.

[0064] Reference Figures 7 to 9 In some embodiments, the clamping block 45 has an integrally connected first C-shaped block 451 and second C-shaped block 452. The inner sides of the first C-shaped block 451 and the second C-shaped block 452 are provided with clamping grooves 453, and the clamping grooves 453 are provided with flexible pads. The clamping grooves 453 extend along a first direction X. In each clamping assembly 41, the first C-shaped block 451 of one clamping block 45 is opposite to the second C-shaped block 452 of another clamping block 45, and the upper and lower inner wall structures of the first C-shaped block 451 of one clamping block 45 match the upper and lower outer wall structures of the second C-shaped block 452 of the other clamping block 45. Therefore, when the two clamping blocks 45 approach each other, the first C-shaped block 451 of one clamping block 45 engages with the second C-shaped block 452 of the other clamping block 45, and the second C-shaped block 452 of one clamping block 45 engages with the first C-shaped block 451 of the other clamping block 45, thereby stably clamping the long quartz rod in the clamping groove, preventing the long quartz rod from shifting or shaking during the cutting process, and improving the cutting accuracy and reliability.

[0065] The quartz rod is gripped in a wraparound manner by clamping blocks with a special C-shaped structure. When the two clamping blocks are closed, they interlock like mortise and tenon joints, forming a closed or nearly closed ring constraint. This effectively increases the clamping contact area, evenly distributes the clamping force, and effectively prevents the quartz rod from being damaged by excessive local pressure during clamping or cutting.

[0066] During the cutting operation, the special C-shaped block in the clamping mechanism 40, which slides bidirectionally, provides a static, multi-directional, and stable constraint for the quartz rod, evenly distributing the clamping force and preventing internal damage or stress concentration caused by clamping before the cutting force is applied. The crank-connecting rod structure of the cutting mechanism 50 transforms linear drive into smooth arc-shaped oscillating feed of the cutting wheel 57, greatly reducing the instantaneous impact and vibration on the workpiece during initial contact and continuous feed. The stable enveloping clamping ensures that the quartz rod will not experience fretting or sudden changes in local stress when subjected to cutting force; while the gentle oscillating cutting makes the cutting force applied to the firmly clamped workpiece controllable and stable.

[0067] Reference Figure 1 and Figure 12 The automatic quartz rod cutting equipment 100 also includes a stacking mechanism 60, which is located on the side of the clamping mechanism. The stacking mechanism 60 includes a stacking disc 61, a positioning sensor 62, a first stacking cylinder 63, and a second stacking cylinder 64. The positioning sensor 62 is located on the side of the stacking disc 61 and faces the clamping mechanism. Further, the central axis of the positioning sensor 62 coincides with the central axis of the long quartz rod in the slot 241. The first stacking cylinder 63 is located on the side of the stacking disc 61 along a first direction X, and its piston rod faces the stacking disc 61; the second stacking cylinder 64 is located on the side of the stacking disc 61 along a second direction Y, and its piston rod faces the stacking disc 61; push plates 65 are respectively provided at the piston rod ends of the first stacking cylinder 63 and the second stacking cylinder 64 (to avoid obstruction). Figure 10 The push plate at the end of the piston rod of the second material feeding cylinder 64 is omitted. The positioning sensor 62 can be a proximity switch or similar product from existing technology.

[0068] During the process of the pushing mechanism 30 pushing the long quartz rod towards the cutting position, when the end of the long quartz rod abuts against the positioning sensor 62, it indicates that the long quartz rod has moved into position. At this time, the pushing mechanism 30 stops pushing, the clamping mechanism 40 clamps the long quartz rod areas on both sides of the cutting space 42, and the cutting mechanism 50 cuts the long quartz rod. After cutting, the second stacking cylinder 64 is used to push the cut short quartz rods onto the stacking tray 61 for orderly stacking. When the number of short quartz rods on the stacking tray 61 reaches the set number, the first stacking cylinder 63 is used to push the short quartz rods out of the stacking tray 61.

[0069] Furthermore, the stacking mechanism 60 also includes a second moving module (not shown in the figure) and a connecting piece 66. The second moving module is disposed on the bottom side of the frame 10 along the first direction X, and the connecting piece 66 is movably disposed on the second moving module along the first direction X. The frame 10 has an opening 11 along the first direction X, and the connecting piece 66 passes through the opening 11 to the side of the stacking tray 61. The positioning sensor 62 is disposed on the connecting piece 66. The second moving module can be a linear guide module, a lead screw motor, or other products in the prior art. The second moving module is used to drive the connecting piece 66 and the positioning sensor 62 on the connecting piece 66 to move along the first direction X, thereby adjusting the distance between the positioning sensor 62 and the cutting space 42 to achieve fixed-length cutting of quartz rods of different lengths.

[0070] Reference Figure 1 , Figure 13 and Figure 14The automatic quartz rod cutting equipment 100 also includes a discharge mechanism 70, which includes a discharge bin 71, a lifting frame 72, and a lifting module 73. The discharge bin 71 is located on the side of the stacking tray 61 along the vertical direction Z, and a discharge port 711 is provided on the discharge bin 71 corresponding to the stacking tray 61. The lifting frame 72 is vertically and flexibly located in the discharge bin 71 through the lifting module 73, and multiple material boxes 721 are provided in the lifting frame 72. The multiple material boxes 721 are arranged at intervals along the vertical direction Z.

[0071] When the number of short quartz bars on the stacking tray 61 reaches the set quantity, the lifting module 73 drives the lifting frame 72 to move, aligning one of the empty material boxes 721 with the stacking tray 61. The first stacking cylinder 63 pushes out the short quartz bars on the stacking tray 61, and these short quartz bars pass through the discharge port 711 and enter the empty material box 721. When the number of short quartz bars on the stacking tray 61 reaches the set quantity again, the lifting module 73 drives the lifting frame 72 to move up or down, aligning the empty material box 721 below or above with the stacking tray 61. The first stacking cylinder 63 then pushes out the short quartz bars on the stacking tray 61 again, and these short quartz bars pass through the discharge port 711 and enter the corresponding empty material box 721. In this way, automatic material discharge is achieved, effectively improving production efficiency.

[0072] Furthermore, the lifting module 73 includes a vertical slide rail 731, a lifting slider 732, a lifting motor 733, a lead screw 734, and a lifting slide block 735. The vertical slide rail 731 and the lead screw 734 are respectively arranged along the vertical direction Z on the inner wall of the discharge bin 71. The lifting motor 733 drives and connects to the lead screw 734. The lifting slider 732 and the lifting slide block 735 are respectively arranged on the side of the lifting rack 72, and the lifting slider 732 cooperates with the vertical slide rail 731, and the lifting slide block 735 is threadedly engaged with the lead screw 734. The lifting motor 733 can drive the lead screw 734 to rotate, thereby driving the lifting slide block 735 to move up and down along the lead screw 734, and thus driving the lifting rack 72 to move up and down. During the up and down movement of the lifting rack 72, the lifting slider 732 cooperates with the vertical slide rail 731 to ensure the stability and reliability of the lifting rack 72 during movement.

[0073] In the automatic quartz rod cutting equipment of this invention, the groove of the feeding mechanism is used to receive the quartz rod, and the pushing mechanism automatically pushes the quartz rod, which greatly reduces labor intensity, shortens the time for quartz rod feeding and positioning, and improves production efficiency to meet the needs of large-scale production. The clamping mechanism uses pressure sensors for real-time monitoring and damping buffer adjustment, combined with a staged clamping control strategy and the control of clamping force differences within and between groups, to accurately control the uniformity of clamping force and avoid cracking of brittle quartz rods due to excessive local pressure or loosening and displacement of the clamping force. After the clamping force reaches the standard and stabilizes, the cutting mechanism drives the cutting wheel to operate along the set cutting space to ensure cutting accuracy and consistency. The equipment works in a coordinated manner, which not only solves the accuracy deviation problem of manual operation and reduces material loss, but also reduces defects such as chipping and breakage, improves the product qualification rate, and provides a stable and reliable pre-production guarantee for quartz boat manufacturing.
