[0065] Another technical problem to be solved by the present invention is a cutting process of a cutting device for a lead frame.

[0066] S1. Loading and positioning of the lead frame: Install the cut lead frame into the positioning member, and perform positioning operations on the cut lead frame through the positioning member;

[0067] S2. Rectification operation of the whole tearing member: By turning on the three-axis adjustment member, complete the rectification operation of the tearing member along the front-back, left-right, up-down directions;

[0068] S3. Tearing operation of the lead frame: After the tearing member completes the rectification operation, the tearing operation of the lead frame can be completed by turning on the tearing member;

[0069] S4. Cutting operation of the lead frame: After completing the tearing operation of the lead frame, inject cutting fluid towards the lead frame, and then turn on the cutting member to complete the cutting operation of the lead frame;

[0070] S5. Rotary adsorption operation of the waste liquid in the positioning member: Each time when the toothed plate is converted from the upward movement state to the downward movement state, it can trigger the linkage operation of the rotary adsorption member to perform rotary adsorption on the waste liquid in the positioning member. When the toothed plate is converted from the downward movement state to the upward movement state, it can drive the rotary adsorption member back to the initial position;

[0071] S6. Cleaning operation of the lead frame waste residue: By turning on the intermittent cleaning member, within one cycle of the movement of the intermittent cleaning member, it can perform knocking operations on the positioning member for half a cycle so that the waste residue can be separated from the lead frame, and in the second half of the cycle, it can perform blowing cleaning operations on the waste residue on the lead frame, and so on in turn for the next movement cycle.

[0072] Generally speaking, compared with the prior art, the beneficial effects of the above technical solutions conceived by the present invention include:

[0073] 1. For the cutting device and cutting process of the lead frame of the present invention, by arranging the tearing member, after the tearing cylinder moves to the position in contact with the lead frame, by turning on multiple groups of tearing cylinders, the connection ends in the lead frame can be clamped. Subsequently, by turning on the switch of the first driving motor, the connecting plate can be driven to move forward or backward. When the connecting plate moves forward or backward, it can drive the rightmost moving plate to displace, so as to drive the scissors frame to displace. After the scissors frame displaces, it can drive multiple groups of tearing cylinders to move synchronously, and can quickly perform tearing operations on the connection ends of the lead frame. Since multiple groups of tearing cylinders can be quickly separated or combined, the whole tearing member can quickly perform tearing operations on the connection ends with different spacings in the lead frame;

[0074] 2. Through the arranged cutting member, the staff can drive the whole cutter to perform a preliminary downward movement operation by turning on the switch of the second driving motor. After the cutter moves above the lead frame, turning on the switch of the fourth electric cylinder can drive the whole cutter to perform a second downward movement operation, which can quickly cut the lead frame after the tear. Through the first preliminary downward movement and the second downward movement, the stability of the cutter when aiming at the lead frame can be ensured;

[0075] 3. Through the arranged cutting member, when the cutter moves downward, it can drive the toothed plate to move downward synchronously. When the second tail rod penetrates into the airbag box and squeezes the airbag in the airbag box, through the arranged airbag, on the one hand, it can effectively prevent the cutter from falling too fast and with too much pressure when falling, resulting in damage to the edge of the lead frame. On the other hand, it can release the water-absorbing particles in the airbag into the positioning member to complete the absorption operation of the cutting fluid waste liquid;

[0076] 4. Through the arranged rotary adsorption member, after the toothed plate moves downward, when the serrated end of the toothed plate meshes with the second driven wheel, it can drive the second driven wheel to move, simultaneously drive the first driven wheel to rotate and drive the guide wheel to rotate. After the guide wheel rotates, it can drive the columnar cam to rotate. At this time, the extension section moves along the top groove of the columnar cam. When the fitting wheel moves to the transition groove, it can drive the through shaft to move downward and drive the lower adsorption cotton board to move upward as a whole. When the fitting wheel moves to the low groove and the external gear comes to the half tooth, it can drive the lower adsorption cotton board to rotate above and the upper adsorption cotton board to rotate below. At this time, after the lower adsorption cotton board adsorbs the cutting fluid waste liquid, it can quickly be replaced by the upper adsorption cotton board. Through the arranged hanging spring, it can be stretched during the downward movement of the through shaft. On the one hand, it can make the lower adsorption cotton board overcome the gravity of the waste liquid and swing quickly after absorbing the waste liquid. On the other hand, it can also make the lower adsorption cotton board provide a stable supporting force to make the lower adsorption cotton board stay stably in the positioning member. In addition, through the arranged lower adsorption cotton board and upper adsorption cotton board, it can further promote the water absorption effect of the water-absorbing particles. When the toothed plate moves upward, it can make the upper adsorption cotton board and the lower adsorption cotton board quickly change positions again, which is equivalent to being able to cleverly promote the replacement of the liquid absorption of the upper adsorption cotton board and the lower adsorption cotton board at each cutting operation to promote the interval liquid absorption and improve the liquid absorption effect;

[0077] 5. Through the intermittent cleaning components, the staff turns on the third driving motor to rotate the toggle wheel and the toggle column. When the toggle column moves to the second toggle groove of the second conversion plate, it can drive the driving column to rotate. After the driving column rotates, it can drive the moving wheel to move along the wave groove, so that the rubber wheel can reciprocate and vibrate the positioning component to loosen the waste residue on the lead frame. When the toggle column moves to the first toggle groove of the first conversion plate, it can drive the fan blade to rotate and blow off the waste residue on the lead frame. Through the intermittent movement of the two, it can be realized. Now, loosening and blowing off impurities at the same time can further improve the waste residue removal effect. In addition, when blowing through the fan blades, on the one hand, it can also blow the waste liquid in the positioning component toward one side of the rotary adsorption component to further improve the overall rotary liquid absorption effect of the rotary adsorption component. On the other hand, when the fan blades are blowing, the water-absorbing particles can also be blown apart to further improve the liquid absorption effect of the water-absorbing particles. On the other hand, when the fan blades are blowing, the lower adsorption cotton board that absorbs the waste liquid can be dried, and the absorption effect is improved when the lower adsorption cotton board continues to participate in absorbing the liquid.

[0089] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0090] The terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the present invention. The terms "comprising", "including" and the like as used herein indicate the presence of the described features, steps, operations and / or components, but do not preclude the presence or addition of one or more other features, steps, operations or components.

[0091] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those of ordinary skill in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0092] In an embodiment, it is given by Figure 1-10 a cutting device for a lead frame, which includes: an operation chassis 1 having an installation chamber therein; a positioning member 2 for positioning the lead frame, which is detachably installed in the installation chamber of the operation chassis 1; a three-axis adjustment member 3, which is detachably installed in the installation chamber of the operation chassis 1, and the three-axis adjustment member 3 is located on one side of the positioning member 2; a slitting member 4 for slitting the lead frame, which is detachably installed on the three-axis adjustment member 3, and the slitting member 4 can be adjusted by the three-axis adjustment member 3 in six directions of front, back, left, right, up and down; a cutting member 5 for cutting the lead frame, which is detachably installed on the other side of the three-axis adjustment member 3, and a toothed plate 59 is contained in the cutting member 5, and the toothed plate 59 can be continuously converted between an upward movement state and a downward movement state; a rotary adsorption member 6 for adsorbing waste liquid in the positioning member 2, which is detachably installed in the installation chamber of the operation chassis 1, wherein when the toothed plate 59 is converted from the upward movement state to the downward movement state, the rotary adsorption member 6 can be triggered to perform a linkage operation, and when the toothed plate 59 is converted from the downward movement state to the upward movement state, the rotary adsorption member 6 can be driven back to the initial position; an intermittent cleaning member 7, which is detachably installed in the installation chamber of the operation chassis 1 and is located on one side of the rotary adsorption member 6.

[0093] An overall idea on which the present invention is based is as follows: by arranging the tearing member 4, after the tearing cylinder 491 moves to a position in contact with the lead frame, by activating multiple groups of tearing cylinders 491, the connection ends in the lead frame can be clamped. Subsequently, by turning on the switch of the first driving motor 43, the connecting plate 46 can be driven to move forward or backward. When the connecting plate 46 moves forward or backward, it can drive the rightmost moving plate 49 to displace, so as to drive the scissors frame 492 to displace. After the scissors frame 492 displaces, it can synchronously drive multiple groups of tearing cylinders 491 to move, and can quickly perform the tearing operation on the connection ends of the lead frame. Since multiple groups of tearing cylinders 491 can be quickly separated or combined, the entire tearing member 4 can quickly perform the tearing operation on the connection ends with different spacings in the lead frame; by arranging the cutting member 5, the operator can drive the cutter 57 to perform a preliminary downward movement operation once by turning on the switch of the second driving motor 54. After the cutter 57 moves above the lead frame, by turning on the switch of the fourth electric cylinder 56, the cutter 57 can be driven to perform a secondary downward movement operation, and can quickly perform the cutting operation on the lead frame after tearing. The preliminary downward movement and the secondary downward movement can ensure the stability of the cutter 57 when aiming at the lead frame; by arranging the cutting member 5, when the cutter 57 moves downward, it can drive the toothed plate 59 to move downward synchronously. When the second tail rod 592 penetrates into the airbag box 26 and squeezes the airbag in the airbag box 26, through the arranged airbag, on the one hand, it can effectively prevent the cutter 57 from falling too fast and with too much pressure, resulting in damage to the edge of the lead frame. On the other hand, it can release the water-absorbing particles in the airbag into the positioning member 2 to complete the absorption operation of the cutting fluid waste liquid;Through the arranged rotary adsorption member 6, after the toothed plate 59 moves downward, when the serrated end of the toothed plate 59 meshes with the second driven wheel 691, it can drive the second driven wheel 691 to move, simultaneously drive the first driven wheel 69 to rotate and drive the guide wheel 67 to rotate. After the guide wheel 67 rotates, it can drive the columnar cam 65 to rotate. At this time, the extension section 692 moves along the top groove of the columnar cam 65. When the fitting wheel 697 moves to the transition groove, it can drive the through-shaft 695 to move downward and drive the lower adsorption cotton plate 698 to move upward as a whole. When the fitting wheel 697 moves to the low groove and the external gear 696 comes to the half-tooth 64, it can drive the lower adsorption cotton plate 698 to rotate upward and the upper adsorption cotton plate 699 to rotate downward. At this time, after the lower adsorption cotton plate 698 adsorbs the cutting fluid waste liquid, it can be quickly replaced with the upper adsorption cotton plate 699. The arranged hanging spring 662 can be stretched during the downward movement of the through-shaft 695. On the one hand, it can enable the lower adsorption cotton plate 698 to overcome the gravity of the waste liquid and swing quickly after absorbing the waste liquid. On the other hand, it can also enable the lower adsorption cotton plate 698 to provide a stable supporting force so that the lower adsorption cotton plate 698 stays stably in the positioning member 2. In addition, the arranged lower adsorption cotton plate 698 and upper adsorption cotton plate 699 can further promote the water absorption effect of the water-absorbing particles. When the toothed plate 59 moves upward, it can enable the upper adsorption cotton plate 699 and the lower adsorption cotton plate 698 to quickly change positions again, which is equivalent to skillfully promoting the replacement of the liquid absorption between the upper adsorption cotton plate 699 and the lower adsorption cotton plate 698 during each cutting operation to improve the liquid absorption effect by interval liquid absorption. Through the arranged intermittent cleaning member 7, the staff turns on the third driving motor 72 to make the dialing wheel 73 and the dialing column 74 rotate. When the dialing column 74 moves to the second dialing groove of the second conversion plate 76, it can drive the driving column 78 to rotate. After the driving column 78 rotates, it can drive the moving wheel 795 to move along the wave groove 79, so that the rubber wheel 793 can reciprocally vibrate the positioning member 2 to loosen the waste residue on the lead frame. When the dialing column 74 moves to the first dialing groove of the first conversion plate 75, it can drive the fan blade 77 to rotate and blow off the waste residue on the lead frame. Through the intermittent movement of the two, it can realize loosening and blowing off impurities while blowing, which can further improve the removal effect of the waste residue. In addition, when the fan blade 77 blows air, on the one hand, it can also blow the waste liquid in the positioning member 2 to converge towards one side of the rotary adsorption member 6 to further improve the overall rotary liquid absorption effect of the rotary adsorption member 6. On the other hand, when the fan blade 77 blows air, it can also blow the water-absorbing particles apart to further improve the liquid absorption effect of the water-absorbing particles. On the third hand, when the fan blade 77 blows air, it can also dry the lower adsorption cotton plate 698 that has absorbed the waste liquid, and the absorption effect is improved when the lower adsorption cotton plate 698 continues to participate in absorbing liquid.;

[0094] Next, a further explanation of the overall usage principle of the positioning member 2 is provided. The positioning member 2 includes: a support base 21, which is detachably installed in the installation chamber of the operation chassis 1; a support template 22, which is detachably arranged on the support base 21. There are two groups of diversion grooves 23 in the support template 22, and a collection groove 24 is also provided in the support template 22; multiple pressing cylinders 25, which are respectively detachably installed on the four side surfaces of the support template 22; an airbag box 26, which is detachably arranged on the support template 22, and the airbag box 26 is located on one side of the collection groove 24. An airbag containing water-absorbing particles is provided in the airbag box 26; an inclined tube 27, which is detachably arranged at the air outlet end of the airbag, and the inclined tube 27 can penetrate out of the airbag box 26.

[0095] Next, a further explanation of the overall usage principle of the positioning member 2 is provided.

By turning on the switch of the second electric cylinder 35, the staff can drive the entire tearing member 4 to be corrected in the left-right direction. By turning on the switch of the third electric cylinder 37, the third electric cylinder 37 can push the third mounting substrate 39 and the entire tearing member 4 to move up or down, so as to complete the correction of the tearing member 4 in the up-down direction.

[0098] Next, a more specific structure and configuration will be given to the entire tearing member 4 for further explanation. The tearing member 4 includes: a tearing base 41, which is detachably mounted on the three-axis adjustment member 3, and an installation frame 42 is detachably mounted on the tearing base 41; a first driving motor 43, which is detachably mounted on the installation frame 42, and the first driving motor 43 can penetrate into the installation frame 42; a connecting lead screw 44, which is rotatably arranged in the installation frame 42, and the connecting lead screw 44 is detachably connected to the output end of the first driving motor 43; a ball base 45, which is slidably arranged in the installation frame 42, and the ball base 45 can be penetrated by the connecting lead screw 44, and an adapter plate 46 is detachably mounted on the ball base 45; a tearing frame 47, which is detachably mounted on the tearing base 41, and there are two groups of cross bars in the tearing frame 47; a positioning plate 48, which is detachably mounted on the two groups of cross bars; a plurality of moving plates 49, which are all slidably arranged on the two groups of cross bars; a tearing cylinder 491 is detachably mounted on the positioning plate 48 and the plurality of moving plates 49, and a scissor frame 492 is also detachably mounted on the positioning plate 48 and the plurality of moving plates 49;

[0099] Next, a further explanation of the overall working principle of the tearing member 4 will be given. When the tearing cylinder 491 moves to a position where it contacts the lead frame, by turning on the plurality of tearing cylinders 491, the connecting ends in the lead frame can be clamped. Subsequently, by turning on the switch of the first driving motor 43, the adapter plate 46 can be driven to move forward or backward. When the adapter plate 46 moves forward or backward, it can drive the rightmost moving plate 49 to move, so as to drive the scissor frame 492 to move.

Since the plurality of tearing cylinders 491 can be quickly separated or combined, the entire tearing member 4 can quickly perform a tearing operation on the connecting ends with different spacings in the lead frame.

[0100] Next, a more specific structure and configuration are given to the entire cutting member 5 for further explanation. The cutting member 5 includes: a cutting frame 51, which is detachably installed in the installation chamber of the operation chassis 1. An external guide plate 52 is detachably installed on the cutting frame 51; a moving template 53, which is slidably arranged on the external guide plate 52; a second driving motor 54, which is detachably installed on the cutting frame 51; a driving lead screw 55, which is rotatably arranged in the external guide plate 52, and one end of the driving lead screw 55 is detachably connected to the output end of the second driving motor 54; a fourth electric cylinder 56, which is detachably installed on the moving template 53, and the output end of the fourth electric cylinder 56 can pass through the moving template 53; a cutter 57, which is detachably arranged on the output end of the fourth electric cylinder 56; a stabilizing rod 58, which is detachably installed on the cutter 57, and the stabilizing rod 58 can pass through the moving template 53; a toothed plate 59, which is detachably installed on the side surface of the cutter 57.

[0101] Next, the operating principle of the entire cutting member 5 is further explained. The staff can drive the entire cutter 5 to perform a preliminary downward movement operation by turning on the switch of the second driving motor 54. After the cutter 57 moves above the lead frame, turning on the switch of the fourth electric cylinder 56 can drive the entire cutter 5 to perform a second downward movement operation, which can quickly cut the lead frame after the tear. Through the first preliminary downward movement and the second downward movement, the stability of the cutter 57 when aiming at the lead frame can be ensured;

[0102] In addition, when the cutter 57 moves downward, it can drive the toothed plate 59 to move downward synchronously. When the second tail rod 592 penetrates into the airbag box 26 and squeezes the airbag in the airbag box 26. Through the arranged airbag, on the one hand, it can effectively prevent the cutter 57 from falling too fast and with too much pressure, which may damage the edge of the lead frame. On the other hand, it can release the water-absorbing particles in the airbag into the positioning member 2 to complete the absorption operation of the cutting fluid waste liquid.

[0103] Next, a more specific structure and configuration are given to the rotary adsorption member 6 as a whole for further explanation. The rotary adsorption member 6 includes: a shaft seat 61, which is detachably installed in the installation chamber of the operation chassis 1, and a built-in shaft 62 is rotatably arranged in the shaft seat 61; an incomplete gear 63, which is detachably arranged on the built-in shaft 62, and a half tooth 64 is provided on the incomplete gear 63, and the half tooth 64 is arranged along the upper semi-circular circumference of the incomplete gear 63; a columnar cam 65, which is detachably installed on the built-in shaft 62, and there is a clamping cavity between the columnar cam 65 and the incomplete gear 63. The bottom of the columnar cam 65 is composed of a bottom groove, an arc transition groove and a top groove. Among them, the bottom groove is in contact with the arc transition groove, and the arc transition groove is in contact with the top groove; a top plate 66, on which a lower support section 661 is detachably installed, and the lower support section 661 is detachably installed on the positioning member 2, and the top plate 66 is penetrated by the built-in shaft 62; a hanging spring 662, which is removably hung on the lower support section 661, and a connecting section 663 is detachably installed on the hanging spring 662; a guide wheel 67, which is detachably installed on the built-in shaft 62; a gear seat 68, which is detachably arranged on the top plate 66, and a second driven wheel 691 and a first driven wheel 69 are rotatably arranged in the gear seat 68. Among them, the second driven wheel 691 and the toothed plate 59 are on the same straight line. The rotary adsorption member 6 further includes: an extension section 692, which is detachably installed at the bottom of the top plate 66, and a through rod 693 is rotatably arranged in the extension section 692, and a built-in sleeve 694 is detachably installed on the through rod 693, and the through rod 693 is detachably connected to the connecting section 663; a through shaft 695, which is detachably installed in the built-in sleeve 694, and an external gear 696 is detachably installed at one end of the through shaft 695. In the initial state, the external gear 696 and the incomplete gear 63 are in an inclined state; a fitting wheel 697, which is detachably installed at one end of the external gear 696 through a rotating shaft. In the initial state, the fitting wheel 697 is in contact with the top groove of the columnar cam 65; a lower adsorption cotton plate 698, which is detachably installed at one end of the through shaft 695, and an upper adsorption cotton plate 699 is detachably installed on the lower adsorption cotton plate 698.

[0104] Next, a further explanation of the overall working principle of the rotary adsorption member 6 is provided. After the toothed plate 59 moves downward, when the serrated end of the toothed plate 59 meshes with the second driven wheel 691, it can drive the second driven wheel 691 to move, simultaneously driving the first driven wheel 69 to rotate and driving the guide wheel 67 to rotate. After the guide wheel 67 rotates, it can drive the cylindrical cam 65 to rotate. At this time, the extension section 692 moves along the top groove of the cylindrical cam 65. When the fitting wheel 697 moves to the transition groove, it can drive the through shaft 695 to move downward and simultaneously drive the lower adsorption cotton plate 698 to move upward as a whole. When the fitting wheel 697 moves to the low groove and the external gear 696 comes to the semi-tooth 64, it can drive the lower adsorption cotton plate 698 to rotate upward and the upper adsorption cotton plate 699 to rotate downward. At this time, after the lower adsorption cotton plate 698 adsorbs the cutting fluid waste liquid, it can be quickly replaced with the upper adsorption cotton plate 699. The arranged hanging spring 662 can be stretched during the downward movement of the through shaft 695. On the one hand, it can enable the lower adsorption cotton plate 698 to overcome the gravity of the waste liquid and swing quickly after absorbing the waste liquid. On the other hand, it can also enable the lower adsorption cotton plate 698 to provide a stable supporting force so that the lower adsorption cotton plate 698 stays stably in the positioning member 2. In addition, the arranged lower adsorption cotton plate 698 and upper adsorption cotton plate 699 can further promote the water absorption effect of the water absorption particles. When the toothed plate 59 moves upward, it can enable the upper adsorption cotton plate 699 and the lower adsorption cotton plate 698 to quickly change positions again, which is equivalent to promoting the replacement of the liquid absorption between the upper adsorption cotton plate 699 and the lower adsorption cotton plate 698 skillfully during each cutting operation to improve the liquid absorption effect by promoting intermittent liquid absorption.

[0105] Next, a more specific structure and construction is given to the intermittent cleaning component 7 as a whole for further explanation. The intermittent cleaning component 7 includes: a mounting base plate 71, which is detachably arranged in the mounting chamber of the operating chassis 1, and a third drive motor 72 is detachably mounted on the mounting base plate 71, and the output end of the third drive motor 72 can be inserted into the mounting base plate 71; a toggle wheel 73, which is detachably arranged on the output end of the third drive motor 72, and a toggle column 74 is detachably mounted on the tail of the toggle wheel 73; a first conversion plate 75, which is rotatably mounted on the mounting base plate 71, and has four groups of first toggle grooves in the first conversion plate 75, and the caliber size of the first toggle groove is mutually adapted to the caliber size of the toggle column 74, and the first conversion plate 75 is located on one side of the toggle wheel 73; a second conversion plate 76, which is rotatably arranged on the mounting base plate On the first conversion plate 71, there are four groups of second toggle grooves in the second conversion plate 76, and the diameter of the second toggle grooves is adapted to the diameter of the toggle column 74, and the second conversion plate 76 is located on the other side of the toggle wheel 73; the fan blade 77 is detachably mounted on the first conversion plate 75; the driving column 78 is detachably arranged on the second conversion plate 76, and a wave groove 79 is provided on the outer circumference of the driving column 78, and the wave groove 79 can surround the driving column 78; the shaft cylinder 791 is detachably arranged on the mounting base plate 71, and a shaft rod 792 is slidably arranged in the shaft cylinder 791, and a rubber wheel 793 is detachably mounted on the shaft rod 792; the linkage rod 794 is detachably mounted on one end of the shaft rod 792, and a moving wheel 795 is also detachably arranged on the linkage rod 794, and the moving wheel 795 can slide in the wave groove 79;

[0106] Next, the overall use principle of the intermittent cleaning component 7 is further explained. The staff turns on the third drive motor 72 to rotate the toggle wheel 73 and the toggle column 74. When the toggle column 74 moves to the second toggle groove of the second conversion plate 76, it can drive the drive column 78 to rotate. After the drive column 78 rotates, it can drive the moving wheel 795 to move along the wave groove 79, so that the rubber wheel 793 can reciprocate and vibrate the positioning component 2, so that the waste residue on the lead frame is loosened from the lead frame. When the toggle column 74 moves to the first toggle groove of the first conversion plate 75, it can drive the fan blade 77 to rotate to blow off the waste residue on the lead frame. Through the intermittent movement of the two, it is possible to loosen and blow away impurities at the same time, which can further improve the waste residue removal effect. In addition, when blowing air through the fan blades 77, on the one hand, it can also blow the waste liquid in the positioning component 2 toward one side of the rotating adsorption component 6 to further improve the overall rotating liquid absorption effect of the rotating adsorption component 6. On the other hand, when the fan blades 77 blow air, the water-absorbing particles can also be blown away to further improve the liquid absorption effect of the water-absorbing particles. On the other hand, when the fan blades 77 blow air, the lower adsorption cotton plate 698 that absorbs the waste liquid can also be dried, and the absorption effect of the lower adsorption cotton plate 698 when it continues to participate in absorbing liquid is improved.

[0107] In some embodiments, more specifically, in order to further improve the stability of the shaft rod 792 during movement, a limit block can be removably installed at the opening of the shaft cylinder 791, and the caliber of the limit block is compatible with the caliber of the shaft cylinder 791, and an inner sliding piece can be removably installed on one end of the shaft rod 792 that passes through the shaft cylinder 791.
