Description

Technical Field

[0001] This invention relates to the field of ceramic filter processing technology, specifically to a multi-functional cutting device for ceramic filter processing. Background Technology

[0002] Ceramic filter sheets are mainly divided into two types: foam ceramic filter sheets and straight-pore ceramic filter sheets. Ceramic filter sheets are usually cut during the green body stage, when the material hardness is relatively low; in a few cases, the finished product after sintering may also be cut.

[0003] A search revealed Chinese patent CN219768725U, which discloses a multifunctional ceramic filter cutting device. This device uses a high-speed rotating cutting wheel to cut the multifunctional ceramic filter, and is easy to operate. However, it still has the following problems:

[0004] 1. It can only process plate-shaped ceramic filter sheets. When cutting round ceramic filter sheets, it is difficult to hold the round ceramic filter sheets, which limits the use of the equipment.

[0005] 2. When feeding circular ceramic filter discs in batches, the ceramic filter discs are relatively fragile, and collisions between them can easily cause the edges to break, resulting in waste of ceramic filter discs and thus increasing the factory's production costs.

[0006] 3. When cutting ceramic filter sheets, the cut ceramic filter sheets lack fixation and are prone to displacement during the cutting process, which can damage them and result in a low yield of finished products. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a multi-functional cutting device for processing ceramic filter sheets. The main solutions are: 1) Difficulty in clamping circular ceramic filter sheets during slitting, limiting the device's usability; 2) The fragility of ceramic filter sheets, leading to edge breakage from collisions and waste, increasing production costs; and 3) Lack of fixation for the cut ceramic filter sheets, causing displacement during cutting and damage to the cutting tool holder, resulting in low yield.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A multi-functional cutting device for processing ceramic filter sheets includes a frame.

[0019] Furthermore, the combined assembly includes a second gear that rotates on one side of the rotating frame, and a second rack that is bolted to the same side of both clamps, and the second rack meshes with the second gear.

[0020] Based on the aforementioned scheme, the workstation conversion module includes a turntable fixed to the top of the frame.

[0056] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0058] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0059] Please see Figures 1-14 As shown, a multi-functional cutting device for processing ceramic filter sheets includes a frame 1. One side of one end of the frame 1 is provided with a blank feeding module 2 for placing multiple ceramic filter sheet blanks. The blank feeding module 2 is also used to separate the ceramic filter sheet blanks. On the same end of the frame 1 as the blank feeding module 2, there is a blank fixing module 3 for fixing the bottom ceramic filter sheet blank to be processed. Between the blank fixing module 3 and the blank feeding module 2, there is a blank pushing module 4 set on the frame 1. The blank pushing module 4 is used to push the filter sheet blanks.

[0060] When filter blanks need to be processed into filter sheets, multiple blanks are placed in the blank feeding module 2. The blank feeding module 2 will separate the multiple blanks to avoid collisions between the blanks during the feeding process. At the same time, the bottom blank can be transported to the blank fixing module 3. The blank pushing module 4 will push the blank to the processing position. When processing is required, the blank fixing module 3 will fix it.

[0061] On the opposite side of the blank pushing module 4 on the frame 1, there is a filter clamping and flipping module 6 for positioning, clamping and transferring the ceramic filter blank. Above the filter clamping and flipping module 6, there is a cutting module 5 set on the frame 1. The cutting module 5 is used to cut the filter blank.

[0062] When the blank needs to be cut, the blank pushing module 4 will push one end of the blank to the filter clamping and flipping module 6. The filter clamping and flipping module 6 will clamp the uncut blank. After clamping, the cutting module 5 will cut the blank. Since the filter is clamped and fixed, the cutting operation can be carried out normally and will not have an adverse effect on the filter.

[0063] The frame 1 is provided with a filter secondary processing module 8 for opening positioning grooves for the filter sheet behind the cutting module 5. Below the filter secondary processing module 8 is a station conversion module 7 for driving the filter sheet to rotate.

[0064] The cut filter sheet is transferred to the station conversion module 7 by the filter sheet clamping and flipping module 6. The station conversion module 7 will drive the filter sheet to change station, so that the filter sheet secondary processing module 8 can complete the opening of one longitudinal hole and two transverse grooves in sequence.

[0065] The entire processing flow is seamless and efficient, enabling the efficient completion of a series of operations from the placement of the blank to its delivery to the processing station. This effectively improves the processing accuracy and production efficiency of ceramic filter sheets, while reducing the intensity of manual operation and increasing the automation level and production efficiency of ceramic filter sheet processing.

[0066] In order to transport the filter blanks at intervals, the blank feeding module 2 in this invention includes a placement frame 201 set on the top of the frame 1. A cover plate 205 is welded between the inner walls of the two sides of the placement frame 201. Multiple rotating grooves 202 are opened at the bottom of the placement frame 201, and a limit plate 203 is rotatably connected in the rotating grooves 202.

[0067] The distance between two adjacent limiting plates 203 is greater than the diameter of the embryo, and the distance between the cover plate 205 and the bottom inner wall of the placement rack 201 is slightly greater than the diameter of the embryo.

[0068] A first electric push rod 204 is fixed to one side of the top of the frame 1 by bolts. The movable end of the first electric push rod 204 is fixed to a top frame 206 that is slidably connected to the placement frame 201 by bolts. The top frame 206 is in contact with the limiting plate 203. The top of the top frame 206 has multiple grooves 207 for one end of the limiting plate 203 to be inserted. Each corner of the bottom of the multiple limiting plates 203 has a placement groove. A roller 208 is slidably connected in the placement groove. The limiting plate 203 always maintains an obtuse angle when it contacts the groove 207.

[0069] When the preform needs to be transported, the first electric push rod 204 is activated. The retraction of the first electric push rod 204 will drive the top frame 206 to move. Under the action of gravity, the limiting plate 203 will rotate in the rotating groove 202, so that one end of the limiting plate 203 enters the groove 207 until the limiting plate 203 does not exceed the bottom inner wall of the placement frame 201. At this time, the cylindrical preform is unobstructed and rolls down. In a very short time, the first electric push rod 204 is restarted to extend, so that the groove 207 squeezes the roller 208, so that the limiting plate 203 rotates in the opposite direction, so that one end of the limiting plate 203 protrudes out of the bottom inner wall of the placement frame 201 again, thereby blocking the preform and completing the single preform falling and transporting action.

[0070] Through the periodic extension and retraction of the first electric push rod 204, the top frame 206 will regularly push the limiting plate 203 to rotate, so that the preforms fall one by one from the gap between adjacent limiting plates 203, realizing the intermittent and orderly conveying of the preforms, effectively avoiding multiple preforms rolling down at the same time and causing blockage, and ensuring the stability and accuracy of the conveying process.

[0071] The roller 208 can transform the sliding friction between the limiting plate 203 and the top frame 206 into rolling friction, reducing wear between components, extending the service life of the device, and reducing the running resistance of the first electric push rod 204, thereby improving the response speed of the overall mechanism.

[0072] In order to fix the blank during the cutting process, the blank fixing module 3 of the present invention includes a clamping plate 301 fixed to the top of the frame 1, a sponge strip 302 is glued to the bottom of one side of the clamping plate 301, a guide frame 303 is fixed to the top of the frame 1 by bolts, a slide 305 is slidably connected to the outer circumference of the guide frame 303, a contour frame 306 is welded to one side of the slide 305, and a second electric push rod 304 is fixed to the top of the frame 1 by bolts, and the movable end of the second electric push rod 304 is fixed to the slide 305.

[0073] When it is necessary to cut the embryo, the second electric push rod 304 is activated to retract, thereby driving the slide 305 and the contour frame 306 to move downward, so that the contour frame 306 and the clamping plate 301 together clamp the embryo and complete the fixation of the embryo.

[0074] The sponge strip 302 can form a flexible buffer on the surface of the blank during the clamping process, avoiding indentations or damage to the surface of the blank due to rigid contact. At the same time, it increases the friction between the clamping plate 301 and the blank, improving the fixing effect. It also provides flexible buffering during the blank's slippage. The material of the sponge strip 302 has a certain elastic deformation capability, which can adapt to the shape contour of the blank during clamping. In addition, the fine texture structure on its surface can further enhance the adhesion to the blank surface, effectively preventing the blank from shifting due to vibration and other factors during the cutting process, and ensuring cutting accuracy.

[0075] The guide frame 303 plays a precise limiting role in the movement direction of the slide 305, ensuring that the contour frame 306 maintains a stable trajectory during the up and down movement, and avoiding clamping misalignment caused by offset.

[0076] The inner contour of the profile frame 306 is adapted to the shape of the blank, which can wrap and fix the blank from multiple angles, so that the blank will not rotate or shake during cutting, ensuring the accuracy of the cutting position.

[0077] In order to push the preform, the preform pushing module 4 in this invention includes a hydraulic cylinder 401 fixed to the top of the frame 1. The movable end of the hydraulic cylinder 401 is fixed with a push plate 402 by bolts. The diameter of the push plate 402 is much smaller than the diameter of the filter preform.

[0078] When the hydraulic cylinder 401 is activated, its extension will cause the push plate 402 to move, thereby bringing the push plate 402 into contact with the blank and pushing the blank towards the filter clamping and flipping module 6.

[0079] During the pushing process, the pusher plate 402, due to its small diameter, can accurately act on the central area of ​​the embryo, avoiding tilting or displacement of the embryo during the pushing process due to uneven force.

[0080] Meanwhile, the surface of the push plate 402 is made of a smooth and wear-resistant material, which will not scratch or damage the surface of the preform when it comes into contact with the preform, thus ensuring the integrity of the preform.

[0081] When the blank is pushed to the predetermined position of the filter clamping and flipping module 6, the hydraulic cylinder 401 stops extending. At this time, the push plate 402 maintains a slight pushing force on the blank to prevent the blank from becoming loose in the subsequent clamping process, thus providing favorable conditions for the stable clamping of the filter clamping and flipping module 6.

[0082] It should be noted that the hydraulic cylinder 401 in this invention is an actuator in the hydraulic system, which achieves the telescopic function by cooperating with the hydraulic system. Those skilled in the art can set it according to actual needs.

[0083] In order to achieve the cutting of the blank, the cutting module 5 in this invention includes a first fixed frame 501 fixed to the top of the frame 1. The first fixed frame 501 is slidably connected to a movable frame 502 on multiple sides. A mounting plate 504 is fixed to one side of the movable frame 502 by bolts. A plurality of positioning holes are provided on one side of the mounting plate 504. The plurality of positioning holes are divided into two groups. A clamping block is fixed to the two positioning holes located on the same horizontal plane by bolts. A laser cutting head 503 is fixed to the clamping block by bolts. The laser cutting head 503 is of model BS20K-CAT. A drive component for driving the movable frame 502 to move horizontally is provided on one side of the first fixed frame 501.

[0084] When it is necessary to cut the embryo, the laser cutting head 503 is activated and driven by the drive assembly to move the laser cutting head 503 horizontally, thereby achieving the cutting of the embryo;

[0085] During the movement of the laser cutting head 503, the high-energy laser beam emitted by it can be precisely focused on the part of the blank to be cut. The local high temperature causes the blank material to melt and separate rapidly, resulting in a smooth and flat cutting surface, avoiding the burrs or cracks that may be produced by traditional mechanical cutting methods.

[0086] The multiple positioning holes on the mounting plate 504 allow the installation position of the laser cutting head 503 to be flexibly adjusted according to actual cutting requirements. When it is necessary to change to a different model or adjust the cutting angle, the position of the laser cutting head 503 can be easily repositioned and fixed by simply loosening the bolts, which improves the adaptability and ease of operation of the equipment.

[0087] During the cutting process, the laser cutting head 503 maintains a certain safe distance from the blank to prevent the blank surface from overheating and being damaged due to being too close, or from being too far away from affecting the cutting accuracy, thus further ensuring the stability and reliability of the cutting operation.

[0088] It should be noted that the laser cutting head 503 in this invention is the core execution component of the laser cutting machine. Its main function is to accurately focus the laser beam generated by the laser and achieve high-quality cutting of materials by guiding the auxiliary gas and maintaining a constant cutting distance. The technicians of this part can set it according to actual needs.

[0089] In order to move the movable frame 502, the driving component of the present invention includes a mounting frame 507 fixed to one side of the movable frame 502. A first motor 506 is fixed to the outer wall of one side of the mounting frame 507 by bolts. A first gear 508 is rotatably connected to the opposite side of the mounting frame 507 and the first motor 506. The first gear 508 and the first motor 506 are connected to a belt through a pulley. A first rack 505 is fixed to one side of the first fixed frame 501 by bolts. The first rack 505 meshes with the first gear 508.

[0090] The first motor 506 is started, and the first motor 506 drives the first gear 508 to rotate through the belt and pulley. Under the meshing of the first gear 508 and the first rack 505, the mounting frame 507 and the moving frame 502 slide synchronously on the first fixed frame 501, thereby realizing the linear displacement of the laser cutting head 503 along the length direction of the first fixed frame 501.

[0091] This gear and rack transmission method features high transmission accuracy and fast response speed, which can ensure that the moving frame 502 remains stable during movement and avoid the accuracy of the cutting position being affected by shaking.

[0092] During the sliding process of the movable frame 502, the mounting frame 507 provides stable support for the first motor 506 and the first gear 508, effectively preventing the transmission components from shifting position or vibrating during high-speed operation, and ensuring the stability and reliability of the drive components during long-term operation.

[0093] In order to clamp and transfer the filter sheet, the filter sheet clamping and flipping module 6 of the present invention includes a baffle 601 fixed to the top of the frame 1. The top of the frame 1 is fixed with a fixed seat 602 by bolts. The fixed seat 602 is rotatably connected to both sides of the fixed seat 603. Two clamps 605 are slidably connected to the outer walls of the rotating frame 603. Rubber pads 606 are glued to the opposite sides of one end of the two clamps 605. A third electric push rod 604 is fixed to one side of the rotating frame 603 by bolts, and the movable end of the third electric push rod 604 is fixed to one of the clamps 605. A joint assembly for making the two clamps 605 move in opposite directions is provided on one side of the rotating frame 603. A second motor 609 is fixed to the inner wall of one side of the fixed seat 602 by bolts. The output shaft of the second motor 609 passes through the fixed seat 602 and is fixed to the rotating frame 603.

[0094] When the blank needs to be cut, the third electric push rod 604 is activated. The extension of the third electric push rod 604 will push one of the clamps 605 to move. Under the action of the combined component, the other clamp 605 will move towards the other side, thereby clamping one end of the blank. After the filter sheet is cut and formed, the second motor 609 is activated. The second motor 609 will drive the rotating frame 603 to rotate, thereby causing the filter sheet to flip and fall onto the station conversion module 7. The station conversion module 7 can accurately transport the filter sheet to the next processing stage, improving the automation level of the production process. The integrated design not only reduces the number of manual intervention links and the risk of human error, but also greatly shortens the production cycle, providing a strong guarantee for enterprises to achieve efficient and stable large-scale production.

[0095] During this process, the rubber pad 606 can increase the friction between the clamp 605 and the filter, preventing the filter from slipping during clamping, and at the same time preventing the clamp 605 from causing indentations or damage to the surface of the filter.

[0096] The design of the combined components ensures the synchronization and stability of the movement of the two clamps 605, making the clamping force uniform and further improving the reliability of the filter transfer process.

[0097] The second motor 609 provides a stable rotary drive torque, and the rotation angle can be adjusted according to actual needs to ensure that the filter can accurately align with the receiving position of the workstation conversion module 7 after flipping, laying the foundation for the smooth progress of subsequent processing.

[0098] In order to enable the two clamps 605 to move toward each other, the combined assembly in this invention includes a second gear 608 rotating on one side of the rotating frame 603, and a second rack 607 is fixed to the same side of both clamps 605 by bolts, and the second rack 607 meshes with the second gear 608.

[0099] During the movement of one of the clamps 605, the second rack 607 will move. Under the action of the second gear 608, the other second rack 607 will move, thereby moving the other clamp 605. The two clamps 605 achieve synchronous reverse movement through the meshing transmission of the second rack 607 and the second gear 608. This design can ensure the consistency of the clamping action and avoid the filter sheet from shifting or deforming due to uneven force caused by asynchronous movement on both sides.

[0100] The rotational accuracy of the second gear 608 directly affects the motion accuracy of the clamp 605. The meshing clearance between the second gear 608 and the second rack 607 is precisely adjusted to effectively reduce the backlash error during transmission, ensuring the positional accuracy of the clamp 605 when clamping and releasing the filter, thereby improving the working stability and reliability of the entire transfer mechanism.

[0101] To enable the transfer of workstations for secondary processing of filter sheets, the workstation conversion module 7 in this invention includes a turntable 701 fixed to the top of the frame 1. The outer circumferential wall of the turntable 701 is provided with multiple clearance grooves 702. Each clearance groove 702 is fixed with a placement box 704 by bolts. A placement plate 706 is slidably connected in the placement box 704. Multiple second fixing frames 703 are fixed to the bottom of the turntable 701 by bolts. A fourth electric push rod 705 is fixed to the top of the second fixing frame 703 by bolts, and the fourth electric push rod 705 is in contact with the placement plate 706.

[0102] When the filter element is moved above the turntable 701 by the filter element clamping and flipping module 6, it is located above the placement plate 706. The clamp 605 releases the clamp on the filter element, and the fourth electric push rod 705 is activated to retract, so that the placement plate 706 and the filter element slide into the placement box 704 under the action of gravity, thereby limiting the position of the filter element horizontally. The turntable 701 is then activated and rotated, thus completing the work position change of the filter element.

[0103] During the rotation of the turntable 701, the structural design of the clearance groove 702 provides a stable installation space for the placement box 704, while avoiding interference with other components when the turntable 701 rotates.

[0104] The sliding fit of the placement plate 706 within the placement box 704 is highly precise, and the gaps between its two sides and the inner wall of the placement box 704 are controlled within a small range to ensure that the filter sheet does not sway laterally as it moves down with the placement plate 706.

[0105] The entire workstation conversion process is seamless and efficient, effectively shortening the transfer time of filter sheets between different processing steps;

[0106] After the filter is processed, restart the fourth electric push rod 705. The extension of the fourth electric push rod 705 will push the placement plate 706 and the filter to move upward, so that the top of the placement plate 706 is flush with the top of the placement box 704. At this time, the filter is removed from the placement box 704 and can be easily taken out.

[0107] The rotation angle of the turntable 701 is controlled by a high-precision servo motor, and its positioning error can be controlled within ±0.02°, ensuring that each placement box 704 can accurately stop at the preset position;

[0108] Meanwhile, the bottom of the turntable 701 is equipped with an annular guide rail and a positioning pin. The annular guide rail ensures the stability of the turntable 701 when it rotates, while the positioning pin is inserted into the corresponding positioning hole when the turntable 701 stops rotating, further improving the positional accuracy of the workstation transition.

[0109] As the placement plate 706 moves upward, the guide grooves on both sides of the placement box 704 guide the placement plate 706 to prevent it from shifting and ensure that the filter can be accurately removed from the placement box 704. In addition, the top edge of the placement box 704 is rounded to avoid scratching the surface of the filter when picking up or putting down the filter.

[0110] It should be noted that the first electric push rod 204, the second electric push rod 304, the third electric push rod 604 and the fourth electric push rod 705 are all existing technologies and can be used with magnetic switches, proximity switches or photoelectric switches to achieve precise control of the push rod extension and retraction displacement. Those skilled in the art can set them according to actual needs.

[0111] Furthermore, rotary table 701 is existing technology, model TK16250B. Rotary table 701 is actually a CNC rotary table with a disc mounted on it. All components or parts mounted on rotary table 701 are mounted on the disc.

[0112] In order to perform secondary processing on the filter, the filter secondary processing module 8 in this invention includes a third fixing frame 801 fixed on the top of the frame 1. Fixing plates 802 are welded to the outer walls of multiple sides of the third fixing frame 801, and a linear motor 803 is provided on one side of the outer wall of the fixing plate 802.

[0113] One of the linear motors 803 has its moving end fixed to an L-shaped frame 804 by bolts. The bottom inner wall of the L-shaped frame 804 is fixed to a third motor 805 by bolts. The output shaft of the third motor 805 is fixed to a first drill bit 806 by a drill chuck. The first drill bit 806 is used for opening longitudinal holes.

[0114] When it is necessary to perform longitudinal drilling on the filter, the third motor 805 is started, which drives the first drill bit 806 to rotate. The corresponding linear motor 803 is started, which drives the L-shaped frame 804 and the first drill bit 806 to move downward, thereby drilling the filter in the longitudinal direction. After the drilling is completed, the linear motor 803 drives the L-shaped frame 804 and the first drill bit 806 to return to the starting position, so as to perform the next drilling operation or change the processing position.

[0115] The moving ends of the other two linear motors 803 are fixed to a U-shaped frame 807 by bolts. A fourth motor 809 is fixed to one inner wall of the U-shaped frame 807 by bolts. A second drill bit 808 is located below the fourth motor 809 and rotates between the inner walls of the two sides of the U-shaped frame 807. The second drill bit 808 and the fourth motor 809 are driven by a belt and a pulley. The third fixed frame 801 for opening the two transverse slots is at a right angle. At the same time, the second drill bit 808 is fixed by a drill chuck. The other end is in contact with the second drill bit 808 by a bearing to provide horizontal support for the second drill bit 808.

[0116] When it is necessary to perform transverse grooving on the filter element, the fourth motor 809 is started. The fourth motor 809 rotates, which drives the second drill bit 808 to rotate through the belt and pulley. The corresponding linear motor 803 is started, which drives the U-shaped frame 807 and the second drill bit 808 to move downward, completing the transverse grooving operation on the filter element. After grooving is completed, the linear motor 803 drives the U-shaped frame 807 and the second drill bit 808 to return to their original position, avoiding unnecessary wear caused by continuous contact between the second drill bit 808 and the filter element. At the same time, it prepares for subsequent transverse grooving operations or adjustment of the processing position.

[0117] Throughout the transverse grooving process, the belt and pulley transmission structure ensures the stability of the rotation of the second drill bit 808 and the efficiency of power transmission, thus effectively guaranteeing the dimensional accuracy and surface quality of the transverse grooving.

[0118] The third fixed frame 801 provides a stable mounting base for each component, and the fixed plate 802 is connected to the third fixed frame 801 by welding, which ensures the structural stability of the linear motor 803 when it is working.

[0119] As a driving component, the linear motor 803's high-precision displacement control capability makes the movement of the L-shaped frame 804 and the U-shaped frame 807 more precise, ensuring that the first drill bit 806 and the second drill bit 808 can accurately align with the target position of the filter during the processing.

[0120] For the two different processing requirements of longitudinal hole opening and transverse grooving, different combinations of motors and drill bits, along with the up-and-down movement of the linear motor 803, have enabled the two processing steps to be carried out independently and quickly switched, thereby improving the automation level and processing efficiency of the secondary processing of filter sheets.

[0121] It should be noted that the first motor 506, the second motor 609, the third motor 805 and the fourth motor 809 in this invention are all existing technologies. They are servo motors with encoders, and the number of rotations and rotation angles of the motor output shaft are controllable and highly accurate. Those skilled in the art can set them according to actual needs.

[0122] The present invention is used in the following steps:

[0123] S1: Place multiple filter blanks between the placement rack 201 and the cover plate 205. Activate the first electric push rod 204. The retraction of the first electric push rod 204 will drive the top frame 206 to move. Under the action of gravity, the limiting plate 203 will rotate in the rotating groove 202, causing one end of the limiting plate 203 to enter the groove 207. At this time, the cylindrical blanks are unobstructed and roll downwards. In a very short time, restart the first electric push rod 204 to extend, causing the groove 207 to squeeze the roller 208, causing the limiting plate 203 to rotate in the opposite direction. This causes one end of the limiting plate 203 to protrude again from the bottom inner wall of the placement rack 201, thus blocking the blanks and completing the single blank falling and conveying action. Through the periodic extension and retraction of the first electric push rod 204, the top frame 206 will regularly push the limiting plate 203 to rotate, causing the blanks to fall one by one from the gap between adjacent limiting plates 203.

[0124] S2: The bottom embryo will come into contact with the sponge strip 302 on one side of the clamping plate 301. When the embryo is stable, the hydraulic cylinder 401 is activated. The extension of the hydraulic cylinder 401 will drive the push plate 402 to move, so that the push plate 402 comes into contact with the embryo and pushes the embryo to move towards the baffle 601, so that one end of the embryo comes into contact with the baffle 601.

[0125] S3: At this time, the third electric push rod 604 is activated. The extension of the third electric push rod 604 will push one of the clamps 605 to move. Under the action of the combined assembly, the other clamp 605 will move towards the other side, thereby clamping one end of the blank.

[0126] S4: At the same time, the second electric push rod 304 is activated to retract, thereby driving the slide 305 and the contour frame 306 to move downward, so that the contour frame 306 and the clamping plate 301 together clamp the embryo, thus completing the fixation of the embryo.

[0127] S5: Start the laser cutting head 503 and drive the laser cutting head 503 to move horizontally through the drive component. During the movement, the high-energy laser beam emitted by the laser cutting head 503 can be precisely focused on the part of the blank to be cut. The blank material is quickly melted and separated by local high temperature. After the cutting is completed, the operation of the laser cutting head 503 is stopped.

[0128] S6: Start the second motor 609. The second motor 609 will drive the rotating frame 603 to rotate, thereby causing the filter to flip and fall above the placement plate 706, and release the clamp 605 from the filter.

[0129] S7: Activate the fourth electric push rod 705 to retract, so that the placement plate 706 and the filter sheet slide into the placement box 704 under the action of gravity, thereby horizontally limiting the position of the filter sheet. Activate the turntable 701, and the turntable 701 rotates, so that the filter sheet enters the next station.

[0130] S8: When it is necessary to perform longitudinal drilling on the filter, start the third motor 805. The third motor 805 drives the first drill 806 to rotate and start the corresponding linear motor 803, thereby driving the L-shaped frame 804 and the first drill 806 to move downward, thereby drilling the filter in the longitudinal direction. After the drilling is completed, the linear motor 803 drives the L-shaped frame 804 and the first drill 806 to return to the starting position, so as to perform the next drilling operation or change the processing position.

[0131] S9: When it is necessary to perform transverse grooving on the filter, start the fourth motor 809. The fourth motor 809 rotates, which drives the second drill bit 808 to rotate through the belt and pulley. Start the corresponding linear motor 803, which drives the U-shaped frame 807 and the second drill bit 808 to move downward to complete the transverse grooving of the filter. After grooving is completed, the linear motor 803 drives the U-shaped frame 807 and the second drill bit 808 to return to their original position, so as to avoid unnecessary wear caused by continuous contact between the second drill bit 808 and the filter. At the same time, it prepares for subsequent transverse grooving operations or adjustment of processing position.

[0132] S10: After the filter sheet processing is completed, restart the fourth electric push rod 705. The extension of the fourth electric push rod 705 will push the placement plate 706 and the filter sheet upward, so that the top of the placement plate 706 is flush with the top of the placement box 704. At this time, the filter sheet is removed from the placement box 704 and can be easily taken out, completing the overall processing of the filter sheet.

[0133] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0134] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
