Description

Technical Field

[0001] This invention relates to stone maintenance technology, specifically to an automatic replacement and reuse device and method for flexible fiber consumables used in stone maintenance. Background Technology

[0002] In current stone maintenance operations, especially on the ground surfaces of large public buildings such as shopping malls, hotels, and office buildings, mobile stone maintenance robots have emerged to replace manual grinding operations.

[0003] Existing stone maintenance equipment, represented by polishing head assembly and stone polishing robot with publication numbers CN111546159A, pad changing device, floor stone care machine and pad changing method with publication numbers CN111557617B, and a pad removal auxiliary mechanism and stone care robot with publication number CN214490607U, has achieved automatic replacement of consumables. However, the replacement method adopted by these devices is to stack multiple layers of consumables along the height direction and then rely on gravity to fall off the old consumables and position the new consumables. However, this method mainly achieves the overall replacement of consumables. When one working surface of the bottom consumable is used up, it is discarded as a whole, while the other side of the consumable is still a brand new working surface. Therefore, it has the disadvantages of low consumable utilization rate and high operating cost.

[0004] If a flipping mechanism is added to this type of equipment to fully utilize both working surfaces of the consumables, additional flipping execution components and corresponding material transfer channels need to be arranged inside the frame. The functional components are often arranged horizontally or in a dispersed manner within the frame, which typically increases the overall size of the machine and reduces space utilization. Therefore, how to achieve automatic flipping and reuse of consumables to improve consumable utilization while maintaining a relatively compact structure and high space utilization is a problem that requires further improvement in existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic replacement and reuse device and method for flexible fiber consumables for stone maintenance, so as to solve the problem that consumables cannot be reused by flipping in the prior art, and that adding a flipping mechanism will easily lead to a decrease in space utilization.

[0044] Another aspect of the present invention provides a method for using an automatic replacement and reuse device for flexible fiber consumables for stone maintenance, comprising the following steps:

[0045] The consumables flipping operation includes the following steps:

[0046] S1. The lifting unit drives the crystallizer to move upward from station B to station A. The conveying unit drives the flipping mechanism to move horizontally from station C to station B. The height adjustment mechanism extends to drive the gripping mechanism to extend upward. The gripping mechanism starts and grips the consumable. After it grips the consumable, the height adjustment mechanism retracts and returns the consumable fixed by the gripping mechanism to the inner box. The flipping drive mechanism drives the inner box to rotate 180°. At this time, the opening of the inner box faces downward.

[0047] S2. The height adjustment mechanism drives the gripping mechanism to extend downward from the opening of the inner box until the consumable contacts the ground. The gripping mechanism separates from the consumable, and the consumable is laid flat on the ground, completing the flipping of the consumable.

[0048] S3. The height adjustment mechanism retracts until the gripping mechanism retracts into the inner box. The flipping drive mechanism drives the inner box to rotate 180° again. At this time, the opening of the inner box faces upward. The conveying unit drives the flipping mechanism to move from station B to station C.

[0049] S5. The lifting unit drives the crystallizer to move down from station A to station B. The crystallizer and consumables are fixed. The crystallizer drives the consumables to rotate and grind the ground.

[0050] The consumable replacement procedure includes the following steps:

[0051] Repeat step S1 of the consumable flipping operation in sequence;

[0052] S21. The conveying unit drives the recycling bin to move from station C to station B. The height adjustment mechanism extends and pushes the consumables grabbed by the gripping mechanism into the recycling bin. The gripping mechanism separates from the consumables, and the consumables fall into the recycling bin. The height adjustment mechanism retracts and drives the lifting plate to retract into the inner box.

[0053] S31. The conveying unit drives the storage box to move from station C to station B. The lifting unit drives the crystallizer to move downward, so that the grinding disc of the crystallizer is in contact with the uppermost consumable in the storage box. The grinding disc and the consumable are fixed. The lifting unit drives the crystallizer to move upward, and the consumable is separated from the storage box.

[0054] S41. The conveying unit drives the storage bin and the tilting mechanism to move from station B to station C respectively;

[0055] S51, the lifting unit drives the crystallizer to move downwards from station A to station B.

[0056] Compared with the prior art, the present invention provides an automatic replacement and flipping reuse device and method for flexible fiber consumables for stone maintenance. Through the gripping mechanism actively gripping and releasing the consumables, and the flipping mechanism driving the consumables to rotate 180°, the working surface of the consumables is flipped, so that both working surfaces of a single consumable can be used, thereby improving the utilization rate of consumables, reducing the replacement frequency, and helping to reduce the cost of using consumables.

[0057] This invention arranges the storage bin and the flipping mechanism vertically in the C-station area of ​​the machine frame cavity. Without increasing the horizontal floor space of the machine frame, it integrates the storage, replacement and flipping of consumables for reuse. Compared with the existing technology of stacking multiple consumables and arranging various functional components separately, this invention makes fuller use of the internal space of the machine frame and the overall size is more compact, which helps to adapt to narrow working environments such as shopping mall aisles and hotel corridors.

[0058] The conveying unit of this invention drives the storage bin and the flipping mechanism to move independently between station B and station C, with their movement paths not overlapping. This enables the reuse of the space at station B and ensures the smooth execution of the consumable flipping and replacement process. Attached Figure Description

[0072] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0073] As attached Figure 1 To be continued Figure 10 As shown:

[0074] This invention provides an automatic replacement and reusable device for flexible fiber consumables for stone maintenance, including a frame 1, a crystallizer 2 installed in the frame 1, a lifting unit 4, a flipping mechanism 7, a storage box 6 with an opening at the top, a conveying unit 10, a flipping drive mechanism 11, a height adjustment mechanism 12, and a gripping mechanism 13.

[0075] The inner cavity of the frame 1 is provided with station A, station B and station C. Station A is located at the top of the inner cavity of the frame 1, station B is located at the bottom of station A, and station C is located on one side of station B in the horizontal direction.

[0076] The lifting unit 4 is mounted on the frame 1 and is used to drive the crystal surface machine 2 to switch positions between station A and station B.

[0077] The storage bin 6 and the tilting mechanism 7 are arranged vertically in layers at station C;

[0078] The conveying unit 10 is installed on the inner wall of the frame 1. The conveying unit 10 is used to drive the tilting mechanism 7 and / or the storage box 6 to switch positions between station B and station C.

[0079] The tilting mechanism 7 includes an outer housing 71, an inner housing 72 with an opening on one side, and a lifting plate 73;

[0080] The outer casing 71 is connected to the conveying unit 10, the inner casing 72 is rotatably mounted inside the outer casing 71 via a rotating shaft, and the lifting plate 73 is mounted inside the inner casing 72.

[0081] The tilting drive mechanism 11 is mounted on the outer housing 71 and is used to drive the inner housing 72 to rotate around the axis of rotation.

[0082] The height adjustment mechanism 12 is installed on the inner box 72. The height adjustment mechanism 12 is used to drive the lifting plate 73 to extend or retract from the opening of the inner box 72.

[0083] The gripping mechanism 13 is installed on the side of the lifting plate 73 near the opening of the inner box 72. The gripping mechanism 13 is used to remove consumables from the grinding disc of the crystallizer 2.

[0084] Station A is the clearance position for Crystal Surface Machine 2. When it is necessary to flip or replace consumables, Crystal Surface Machine 2 is raised to Station A to make room for the horizontal movement of the storage box 6 and the flipping mechanism 7. Station B is the normal working position of Crystal Surface Machine 2. In this position, Crystal Surface Machine 2 drives the consumables to rotate to grind and polish the ground.

[0085] Station C is the standby station for storage box 6 and flipping mechanism 7. The vertical lifting motion of crystal face machine 2 and the translational motion of storage box 6 and flipping mechanism 7 do not interfere with each other in space. When crystal face machine 2 is located at station A, storage box 6 and flipping mechanism 7 can switch positions between station B and station C.

[0086] When the storage box 6 and the flipping mechanism 7 are located at station C, the crystallizer 2 can switch between station A and station B, providing ample operating space for the flipping and replacement of consumables without expanding the horizontal floor area of ​​the frame 1.

[0087] The flipping drive mechanism 11 can be a rotary motor (such as a servo motor or a stepper motor) that drives the inner box 72 to rotate in conjunction with gear transmission, or it can be a pneumatic rotary cylinder or a hydraulic swing motor that drives the inner box 72 to rotate. Any of the above driving methods can achieve a 180° flip of the inner box 72.

[0088] The gripping mechanism 13 is a needle-shaped gripper, and its fixed end is fixedly connected to the outer wall of the lifting plate 73. The gripping mechanism 13 can be pneumatically driven (by controlling the extension and retraction of the steel needle with compressed air) or electrically driven (by driving the steel needle with a micro linear motor) to adapt to different environments or electrification control requirements. The gripping mechanism 13 achieves gripping by inserting the inclined steel needle into the interior of the flexible fiber consumable and releases the consumable when the steel needle is retracted. It is particularly suitable for gripping breathable and flexible consumables such as steel wool pads and scouring pads.

[0089] In one embodiment of the present invention, a recycling bin 8 is also included. The recycling bin 8 is disposed at station C. The storage bin 6, the flipping mechanism 7 and the recycling bin 8 are arranged in a vertical direction, and the recycling bin 8 is located below the storage bin 6 and the flipping mechanism 7.

[0090] The recycling bin 8 is located at the bottom. The storage bin 6 and the flipping mechanism 7 can be interchanged above the recycling bin 8 in the initial state. The above vertical layered layout makes the projections of the storage bin 6, the flipping mechanism 7 and the recycling bin 8 overlap in the horizontal direction, reducing the horizontal space required for the arrangement of the three and improving the space utilization rate inside the frame 1.

[0091] In one embodiment of the present invention, the conveying unit 10 includes three sets of translation components with the same structure, and the three sets of translation components are respectively connected to the storage box 6, the flipping mechanism 7 and the recycling box 8 in a one-to-one correspondence.

[0092] Each translation component includes a slider 103, a slide rail 104, and a power drive unit;

[0093] The slide rail 104 is fixedly installed on the inner wall of the frame 1;

[0094] The slider 103 is slidably installed on the outside of the slide rail 104. The sliders 103 of the three sets of translation components are respectively fixedly connected to the outer wall of the storage box 6, the outer wall of the outer box 71 of the flipping mechanism 7, and the outer wall of the recycling box 8.

[0095] The power drive unit is installed on the inner wall of the frame 1 and is used to drive the corresponding slider 103 to slide along the slide rail 104 so as to independently switch the storage box 6, the flipping mechanism 7 and / or the recycling box 8 between station B and station C.

[0096] In one embodiment of the present invention, the power drive unit includes a first drive source 101, a clamping plate 102, a transmission belt 105, and a pulley 106;

[0097] The first drive source 101 is fixedly installed on the inner wall of the frame 1;

[0098] One pulley 106 is rotatably mounted on the inner wall of the frame 1, and the other pulley 106 is fixedly mounted on the output end of the first drive source 101;

[0099] A transmission belt 105 is fitted on the outer side of the two pulleys 106, and the two pulleys 106 are connected by the transmission belt 105.

[0100] The clamping plate 102 is fixedly installed on the transmission belt 105, and one side of the clamping plate 102 is fixedly connected to the storage box 6 / tilting mechanism 7 or recycling box 8.

[0101] The first drive source 101 can be a servo motor or a stepper motor (such as Leadshine Technology's closed-loop stepper series) to achieve translational positioning. Alternatively, it can be a general AC geared motor paired with photoelectric limit switches to meet different application scenarios with varying cost and precision requirements.

[0102] In one embodiment of the present invention, one side of the slider 103 of a set of translation components is fixedly connected to the outer wall of the storage box 6, and the clamping plate 102 of the set of translation components is fixedly connected to the outer wall of the storage box 6.

[0104] The slider 103 of the third translation component is fixedly connected to the outer wall of the recycling bin 8 on one side, and the clamping plate 102 of the translation component is fixedly connected to the outer wall of the recycling bin 8.

[0105] In one embodiment of the present invention, a gripping unit 5 is provided on the top of the storage box 6. The gripping unit 5 includes a second lifting member 51 and a suction cup 52 installed on the output end of the second lifting member 51. The fixed end of the second lifting member 51 is fixedly installed on the top of the inner cavity of the frame 1. The suction cup 52 opens towards the top of the storage box 6 and is used to pick up the consumable separator paper at the top.

[0106] The second lifting component 51 can be a pneumatic slide cylinder (such as the SMC MXH series) or an electric push rod (such as the LINAK LA series) to realize the vertical lifting action of the suction cup 52. The suction cup 52 is also connected to an air pump that generates negative pressure for extraction. A separator paper is provided between the consumables to prevent adjacent consumables from sticking together due to fiber entanglement. When the consumables are taken from the storage box 6, the separator paper is at the top. In order to eliminate the influence of the separator paper on the crystallizer 2 in taking consumables, the suction cup 52 is used to pick up the separator paper of the consumables at the top and transfer it to the recycling box 8.

[0107] In one embodiment of the present invention, the lifting unit 4 includes a first power component 41, a first threaded rod 42, a mounting bracket 43, and a guide rod 44;

[0108] The first power component 41 is mounted on the frame 1;

[0109] The first threaded rod 42 is arranged vertically, with one end fixedly installed at the output end of the first power component 41, and the other end of the first threaded rod 42 rotatably connected to the outer wall of the frame 1.

[0110] The guide rod 44 is fixedly installed in the inner cavity of the frame 1 and is arranged parallel to the first threaded rod 42;

[0111] The mounting bracket 43 has a threaded hole that is threaded to the outer side of the first threaded rod 42, and a guide hole that is slidably connected to the guide rod 44. One side of the mounting bracket 43 is fixedly connected to the outer wall of the crystallizer 2.

[0112] The first power component 41 can be a servo motor (such as the Panasonic A6 series) and a brake to achieve rapid response and vertical positioning of the crystallizer 2 between station A and station B; it can also be a stepper motor, a linear cylinder (such as the SMC CG series heavy-duty cylinder) or a hydraulic cylinder (such as the Rexroth CD series) to meet the requirements of different working conditions such as accuracy, speed or thrust.

[0113] In one embodiment of the present invention, the height adjustment mechanism 12 includes a second drive source 121, a connecting rod 122, a first hinge arm 123, a second hinge arm 124, a first guide plate 125, and a second guide plate 126.

[0114] The second drive source 121 is hinged to the inner housing 72;

[0115] The connecting rod 122 is movably mounted at the output end of the second drive source 121;

[0116] The middle part of the first hinge arm 123 and the middle part of the second hinge arm 124 are hinged together by a pivot.

[0117] One end of the first hinge arm 123 is rotatably mounted on the end of the connecting rod 122, and the other end of the first hinge arm 123 is hinged to the outer wall of the lifting plate 73.

[0118] The end of the second hinge arm 124 away from the connecting rod 122 is hinged to the bottom plate of the inner box 72, and the other end of the second hinge arm 124 is rotatably mounted with a roller.

[0119] The first guide plate 125 is fixedly installed on the inner wall of the inner box 72 and is located above the connecting rod 122. The connecting rod 122 can move along the trajectory direction of the first guide plate 125.

[0120] The second guide plate 126 is fixedly installed at the bottom of the lifting plate 73, and the roller is rotatably installed inside the second guide plate 126. The roller can move along the trajectory of the second guide plate 126.

[0121] The second drive source 121 can be a micro servo electric cylinder (such as the IAI RCP series), a mini cylinder, or a micro hydraulic cylinder. In this embodiment, the second drive source 121 consists of a stepper motor and a second threaded rod installed at the output end of the stepper motor. The connecting rod 122 is penetrated by the second threaded rod, and the connecting rod 122 is threadedly connected to the outer side of the second threaded rod to drive the connecting rod 122 to move in the trajectory direction of the first guide plate 125.

[0122] In one embodiment of the present invention, the power transmission path of the conveying unit 10 is achieved by directly fixing the clamping plate 102 and the slider 103, and fixing the slider 103 and the corresponding box.

[0123] The clamping plate 102 drives the slider 103, which is directly fixed to it, to slide on the slide rail 104. The slider 103 drives the storage box 6, the flipping mechanism 7, or the recycling box 8, which is fixed to it, to move synchronously, thereby realizing the independent position switching of the storage box 6, the flipping mechanism 7, and the recycling box 8 between station B and station C.

[0124] The connection stiffness between the clamping plate 102 and the slider 103 is not affected by the thickness of the box wall or the installation position of the box. The slider 103 performs two functions: first, it serves as a force transmission transition between the clamping plate 102 and the transmission belt 105; second, it serves as a guide that slides along the slide rail 104.

[0125] Specifically, regarding the three sets of translation components:

[0126] One side of the slider 103 of one of the translation components is fixedly connected to the outer wall of the storage box 6, and the clamping plate 102 is directly fixedly connected to the other side of the slider 103. The storage box 6, the slider 103 and the clamping plate 102 form a rigid linkage structure.

[0127] One side of the slider 103 of the other translation component is fixedly connected to the outer wall of the outer box 71, and the clamping plate 102 is directly fixedly connected to the other side of the slider 103. The outer box 71, slider 103 and clamping plate 102 form a rigid linkage structure.

[0128] The slider 103 of the third translation component is fixedly connected to the outer wall of the recycling bin 8 on one side, and the clamping plate 102 is directly fixedly connected to the other side of the slider 103. The recycling bin 8, the slider 103 and the clamping plate 102 form a rigid linkage structure.

[0129] In one embodiment of the present invention, a method of using an automatic replacement and reuse device for flexible fiber consumables for stone maintenance includes the following steps:

[0130] The process of flipping consumables includes the following steps:

[0131] S1. Lifting unit 4 drives crystallizer 2 to move upward from station B to station A. Conveying unit 10 drives flipping mechanism 7 to move horizontally from station C to station B. Height adjustment mechanism 12 extends to drive gripping mechanism 13 to extend upward. After gripping consumables, height adjustment mechanism 12 retracts to retract the consumables fixed by gripping mechanism 13 into inner box 72. Flipping drive mechanism 11 drives inner box 72 to rotate 180°. At this time, the opening of inner box 72 faces downward.

[0132] S2. The height adjustment mechanism 12 drives the gripping mechanism 13 to extend downward from the opening of the inner box 72 until the consumable contacts the ground. The gripping mechanism 13 separates from the consumable, and the consumable is laid flat on the ground, completing the flipping of the consumable.

[0133] S3. The height adjustment mechanism 12 retracts to the gripping mechanism 13 and retracts into the inner box 72. The flipping drive mechanism 11 drives the inner box 72 to rotate 180° again. At this time, the opening of the inner box 72 faces upward. The conveying unit 10 drives the flipping mechanism 7 to move from station B to station C.

[0134] S5. Lifting unit 4 drives crystal surface machine 2 to move down from station A to station B. The grinding disc of crystal surface machine 2 is fixed with the consumables. Crystal surface machine 2 drives the consumables to rotate and grind the ground.

[0135] The consumable replacement procedure includes the following steps:

[0136] Repeat step S1 of the consumable flipping operation in sequence;

[0137] S21, the conveying unit 10 drives the recycling bin 8 to move from station C to station B. The height adjustment mechanism 12 extends and pushes the consumables grabbed by the gripping mechanism 13 into the recycling bin 8. The gripping mechanism 13 separates from the consumables, and the consumables fall into the recycling bin 8. The height adjustment mechanism 12 retracts and drives the lifting plate 73 to retract into the inner box 72.

[0138] S31. The conveying unit 10 drives the storage box 6 to move from station C to station B. The lifting unit 4 drives the crystal surface machine 2 to move downward, so that the grinding disc of the crystal surface machine 2 is in contact with the uppermost consumable in the storage box 6. The grinding disc and the consumable are fixed. The lifting unit 4 drives the crystal surface machine 2 to move upward, and the consumable is separated from the storage box 6.

[0139] S41, conveying unit 10 drives storage bin 6 and tilting mechanism 7 to move from station B to station C respectively;

[0140] S51, the lifting unit 4 drives the crystallizer 2 to move down from station A to station B.

[0141] Taking steel wool pads as an example, the operation process of flipping and reusing steel wool pads is explained as follows:

[0142] Steel wool pads are pre-stacked in the top cavity of storage box 6, arranged neatly layer by layer from bottom to top. Separator paper is laid between adjacent steel wool pads to prevent fibers from tangling. Crystallizer 2 and lifting unit 4 are started. Lifting unit 4 drives crystallizer 2 to stay at position B. The steel wool pads installed on the grinding disc at the output end of crystallizer 2 contact the ground and rotate to polish and / or grind the ground. Walking unit 3 drives the device to move along a predetermined trajectory. When the side of the steel wool pad in contact with the ground is exhausted or the ground can no longer be treated (specifically, this can be determined by detecting a decrease in the working current of crystallizer 2 or the working time reaching a preset threshold), the steel wool pad needs to be flipped or replaced with a new steel wool pad.

[0143] When it is necessary to flip the steel wool pad, the device performs the following operations:

[0144] S1. Lifting unit 4 drives crystallizer 2 to move upward from station B to station A. The translation component in conveying unit 10, corresponding to the flipping mechanism 7, drives the flipping mechanism 7 to move horizontally from station C to station B. At this time, the output end of the gripping mechanism 13 faces the steel wool pad at the bottom of the crystallizer 2's grinding disc. Height adjustment mechanism 12 drives the gripping mechanism 13 on lifting plate 73 to extend upward from the opening of inner box 72. The gripping mechanism 13 starts, and its output end extends an inclined claw that pierces into the steel wool pad. Lifting unit 4 then drives crystallizer 2 upward, and the steel wool pad detaches from the crystallizer 2's grinding disc under the pull of gripping mechanism 13.

[0145] The height adjustment mechanism 12 retracts, pulling the lifting plate 73 and the gripping mechanism 13 on it back into the inner box 72. The flipping drive mechanism 11 drives the inner box 72 to rotate 180° around the axis of rotation. At this time, the opening of the inner box 72 faces downward, and the used side of the steel wool pad faces upward and the unused side faces downward.

[0146] S2. The height adjustment mechanism 12 drives the gripping mechanism 13 on the lifting plate 73 to extend downward from the opening of the inner box 72 until the steel wool pad contacts the ground. The inclined claws on the gripping mechanism 13 retract, and the steel wool pad is laid flat on the ground, completing the flipping.

[0147] S3. After the height adjustment mechanism 12 retracts until the lifting plate 73 retracts into the inner box 72, the flipping drive mechanism 11 drives the inner box 72 to rotate 180° again around the axis of rotation. At this time, the opening of the inner box 72 faces upward. The translation component in the conveying unit 10, which is connected to the flipping mechanism 7, drives the flipping mechanism 7 to move horizontally from station B to station C.

[0148] S4, Lifting unit 4 drives crystal surface machine 2 to move down from station A to station B. The grinding disc of crystal surface machine 2 is fixed by magnetic attraction of steel wool pad. Crystal surface machine 2 continues to drive steel wool pad to rotate and continue to grind the ground.

[0149] At this point, the operation of flipping and reusing the steel wool pad is complete.

[0150] The steel wool pad replacement procedure includes the following steps:

[0151] Repeat step S1 of the consumable flipping operation in sequence;

[0152] S21. The translation component in the conveying unit 10, which is connected to the recycling bin 8, drives the recycling bin 8 to move horizontally from station C to station B. The height adjustment mechanism 12 extends and pushes the discarded consumables downward to the bottom of the inner cavity of the recycling bin 8. The inclined claw on the gripping mechanism 13 retracts, the consumables separate from the gripping mechanism 13, and the discarded consumables fall naturally back into the bottom space of the recycling bin 8. The height adjustment mechanism 12 retracts and drives the lifting plate 73 to retract from the opening of the inner box 72 into the inner box 72.

[0153] S31. The translation component connected to the storage box 6 in the conveying unit 10 drives the storage box 6 to move horizontally from station C to station B. The lifting unit 4 drives the crystal surface machine 2 to move downward, so that the grinding disc of the crystal surface machine 2 contacts the uppermost consumable in the top cavity of the storage box 6. The magnet or electromagnet on the grinding disc attracts and fixes the consumable. The lifting unit 4 drives the crystal surface machine 2 to move upward, and the consumable separates from the storage box 6.

[0154] S41. The translation component connected to the storage box 6 and the translation component connected to the flipping mechanism 7 in the conveying unit 10 respectively drive the storage box 6 and the flipping mechanism 7 to move horizontally from the B station position to the C station position.

[0155] S51, the lifting unit 4 drives the crystallizer 2 to move down from station A to station B, thus completing the replacement of consumables.

[0156] In one embodiment of the present invention, a power supply unit 9 is also fixedly installed inside the frame 1. The power supply unit 9 is preferably a lithium battery of the storage battery series, but a fuel generator can also be used, depending on the specific requirements.

[0157] The control unit is also fixedly installed inside the frame 1 as the control core of the entire device. It has a complete operation control program pre-stored inside. The control unit receives feedback signals from various sensors (such as position sensors, current detection sensors, pressure sensors, magnetic switches, etc.) through the input interface, and sends control commands to various electrical actuators through the output interface to form a closed-loop control.

[0158] In one embodiment of the present invention, a magnet or electromagnet with magnetic attraction force is fixedly installed on the grinding disc of the crystallizer 2. The consumable material is any flexible fiber consumable material that can adapt to the working requirements of the crystallizer 2, such as steel wool pad, scouring pad, or polishing pad. The consumable material can be attracted by the magnet or electromagnet on the grinding disc and kept stable, and will not fall off naturally. A buffer pad with hair-like fibers on its surface is also attached to the lower surface of the grinding disc. The magnet / electromagnet and the buffer pad provide double fixation for the consumable material: the magnetic attraction force provided by the magnet / electromagnet is the main fixing force, and the hair-like fibers on the surface of the buffer pad and the consumable material (steel wool fiber) interlock to form an auxiliary fixing force. Even when the magnetic attraction force weakens momentarily due to vibration, the interlocking effect of the buffer pad can still keep the consumable material from falling off, ensuring that the consumable material remains stable during high-speed rotation, vertical lifting, and horizontal conveying.

[0159] The magnets or electromagnets on the grinding disc of the crystallizer are arranged as follows: multiple holes are evenly drilled on the surface of the grinding disc, and the magnets or electromagnets are embedded in the holes to ensure uniform distribution of magnetic attraction. The electromagnets can control the on / off state of the current to instantly turn the magnetic attraction on and off, facilitating the handling of consumables.

[0160] In one embodiment of the present invention, the vertical relative positions of the storage bin 6 and the tilting mechanism 7 above the recycling bin 8 can be flexibly interchanged according to actual working conditions during the initial installation of the device. Specifically, there are two initial installation methods:

[0161] Installation Method 1: The storage bin 6 is located above the flipping mechanism 7. In this installation method, the storage bin 6 is close to the grinding disc of the crystallizer 2. The path for the crystallizer 2 to retrieve new consumables from the storage bin 6 is shorter, which is suitable for operation scenarios with high consumable replacement frequency. The flipping mechanism 7 is located below the storage bin 6. When performing the flipping operation, the flipping mechanism 7 moves from station C to station B. The opening of its inner box 72 faces upward to receive the consumables taken from the grinding disc of the crystallizer 2. After the flipping is completed, it extends downward to the ground to release the consumables.

[0162] Installation Method 2: The flipping mechanism 7 is located above the storage bin 6. In this installation method, the flipping mechanism 7 is close to the grinding disc of the crystallizer 2. When performing the flipping operation, the extension distance of the gripping mechanism 13 is shorter, and the response speed is faster. This method is suitable for operation scenarios that require frequent flipping. The storage bin 6 is located below the flipping mechanism 7. When the crystallizer 2 retrieves new consumables, it needs to pass through the area where the flipping mechanism 7 is located. However, the translation path of the storage bin 6 and the translation path of the flipping mechanism 7 are independent of each other and do not interfere with each other.

[0163] In both installation methods described above, the recycling bin 8 is fixedly located at the lowest position to collect falling debris and grinding or polishing slurry adhering to consumables during the grabbing, flipping, and replacement processes, preventing ground contamination. Regardless of installation method one or method two, the device can fully perform consumable flipping and reuse operations and consumable replacement operations, with the operating procedures remaining unchanged.

[0164] The design of interchangeable initial installation positions of storage bin 6 and flipping mechanism 7 has the following advantages: First, users can choose a suitable installation method according to actual operational needs (such as material consumption rate, flipping frequency, etc.), improving the applicability of the device; Second, both installation methods can achieve complete automatic feeding, automatic flipping, and waste recycling functions, proving that the technical solution of the present invention does not depend on a specific vertical order of storage bin 6 and flipping mechanism 7, and has high fault tolerance and adaptability; Third, others cannot circumvent the protection scope of this patent by simply swapping the positions of storage bin 6 and flipping mechanism 7, because the core of the protection of the present invention lies in the collaborative action logic and process relationship of each functional module, rather than a specific spatial order.

[0165] In one embodiment of the present invention, the lifting unit 4 is used to drive the crystallizer 2 to switch positions between station A and station B. The lifting unit 4 can be implemented by a screw drive: the first power component 41 drives the threaded rod 42 to rotate, the threaded hole on the mounting bracket 43 cooperates with the threaded rod 42, and under the guidance of the guide rod 44, the mounting bracket 43 drives the crystallizer 2 to move linearly in the vertical direction;

[0166] In addition to screw drive, the lifting unit 4 can also be driven by chain drive: the first power component 41 drives the sprocket to rotate, the chain is fixedly connected to the mounting bracket 43, and the rotation of the sprocket drives the chain and the mounting bracket 43 to move in the vertical direction. Chain drive is suitable for working conditions with large lifting stroke.

[0167] In addition, the lifting unit 4 can also be driven by a hydraulic cylinder or a pneumatic cylinder: the piston rod of the hydraulic cylinder or pneumatic cylinder is fixedly connected to the mounting bracket 43, and the crystallizer 2 is driven to move in the vertical direction by the extension and retraction of the piston rod. The hydraulic cylinder driving method is suitable for working conditions that require a large lifting force, while the pneumatic cylinder driving method is suitable for working conditions that require a fast response.

[0168] In one embodiment of the present invention, the conveying unit 10 is used to drive the storage bin 6, the tilting mechanism 7, and the recycling bin 8 to switch positions between station B and station C. The conveying unit 10 can be implemented by a translation method in which a slide rail 104 and a slider 103 cooperate: the slide rail 104 is fixedly installed on the inner wall of the frame 1, the slider 103 is slidably installed on the outer side of the slide rail 104, and the first drive source 101 drives the slider 103 to slide horizontally along the slide rail 104 through the transmission belt 105, thereby realizing the translation and positioning of each functional module.

[0169] In addition to the slide rail method, the conveying unit 10 can also be implemented using a guide rail method: the guide rail is fixedly installed on the inner wall of the frame 1, and the slider 103 is slidably installed on the outer side of the guide rail. The slider 103 is driven to slide horizontally along the guide rail by a motor-driven lead screw or synchronous belt. In addition, the conveying unit 10 can also be implemented using a belt conveyor method: the belt and pulley 106 work together to drive the horizontal movement of each functional module.

[0170] In addition to servo motors or stepper motors, the drive source for the conveying unit 10 can also be a pneumatic motor or a hydraulic motor.

[0171] In one embodiment of the present invention, the flipping drive mechanism 11 is used to drive the inner housing 72 to rotate 180° around the axis of rotation. The flipping drive mechanism 11 can use a rotary motor (such as a servo motor or stepper motor) in conjunction with gear transmission or worm gear transmission to achieve the flipping of the inner housing 72. The motor drive method is suitable for working conditions that require precise angle control.

[0172] In addition, the flipping drive mechanism 11 can also be implemented by a pneumatic rotary cylinder: the output shaft of the rotary cylinder is connected to the rotating shaft of the inner housing 72, and the rotor of the rotary cylinder is driven to rotate 180° by compressed air. The pneumatic rotation method is suitable for working conditions that require rapid flipping and do not require precise intermediate position positioning.

[0173] The tilting drive mechanism 11 can also be implemented using a hydraulic swing motor: the output shaft of the hydraulic swing motor is connected to the rotating shaft of the inner housing 72, and the rotor of the swing motor is rotated 180° by hydraulic drive. The hydraulic swing motor method is suitable for working conditions that require a large tilting torque.

[0174] In one embodiment of the present invention, the gripping mechanism 13 is a needle-shaped gripper, which grips the flexible fiber consumable by inserting an inclined steel needle into it and releases the consumable when the steel needle is retracted. The driving source of the gripping mechanism 13 can be a pneumatic drive (such as a miniature cylinder), which uses compressed air to drive the extension and retraction of the steel needle. The pneumatic method has the advantages of fast response speed and simple structure.

[0175] The drive source for the gripping mechanism 13 can also be electric drive (such as a micro linear motor or an electromagnet with a return spring), which controls the extension and retraction of the steel needle through an electrical signal. The electric method has the advantages of high control precision and no need for an air source.

[0176] The gripping mechanism 13 can also be driven by an electromagnetic drive, which drives the steel needle to move by the attraction and release of the electromagnet, and is suitable for working conditions that require a compact structure.

[0177] In one embodiment of the present invention, the consumables are packaged according to standardized specifications at the time of manufacture. Specifically, the steel wool pads are made into thin sheets in the factory, cut neatly according to the required shape, and each sheet is separated by a separator paper to prevent the fibers from tangling. After packaging, the packaged consumables can be directly placed into the storage box 6 without the need for manual on-site handling or placement, further reducing manual intervention.

[0178] The standardized packaging of consumables has the following advantages: First, it ensures that the size, thickness and shape of each consumable are consistent, which facilitates the precise adsorption and positioning of the grinding disc of the crystallizer 2; Second, the setting of the separator paper avoids the fiber entanglement between adjacent consumables, ensuring that only one consumable is used at a time; Third, standardized packaging makes the filling of the storage box 6 more convenient and efficient, and the operator only needs to put the whole package of consumables into the storage box 6.

[0179] In one embodiment of the present invention, a walking unit 3 is installed at the bottom of the frame 1. The walking unit 3 can be implemented using conventional mobile driving methods known in the art, such as a dual-wheel differential drive structure, consisting of two independently driven walking wheels (each driven independently by a free walking motor) and at least one universal support wheel. The device can achieve straight-line movement, turning and rotation in place by controlling the speed difference between the left and right walking wheels.

[0180] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
