Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of detection and correction equipment, and in particular to a fan blade balance detection and correction device. Background Art
[0002] The fan blade is an important component of the air flow conveying equipment. It is driven by a motor to rotate to generate wind power and achieve air convection. During daily use of the fan blade, "dynamic balance" is one of the important indicators for the normal operation of the fan blade. As a rotating body, if the mass distribution of the fan blade is uniform, the centrifugal forces generated during the rotation of the fan blade can cancel each other out, ensuring the smooth rotation of the fan blade and the normal output of the air volume.
[0003] If there is a problem with the dynamic balance of the fan blade, the unbalanced rotation will cause additional mechanical stress, resulting in faster wear of the connecting components, bearings and other key components, and easily leading to an increase in the equipment failure rate; for an unbalanced rotating body, more energy is required to overcome the additional resistance and friction, which will lead to a reduction in the energy efficiency of the equipment and an increase in the operating cost; moreover, the unbalanced fan blade will generate greater vibration and noise, and at the same time, it will also cause a decrease in the air volume and air pressure output by the fan, reducing the cooling efficiency.
[0004] When encountering the "imbalance" of the fan blade, the conventional method is generally to detect the data of the "imbalance" of the fan blade by a balance detector, and then adopt the method of adding weight, such as adding counterweight blocks, filling soil or dispensing glue on the lighter side of the fan blade, to adjust the mass distribution of the fan blade so as to improve the "imbalance" situation of the fan blade.
[0005] Regarding the method of adding counterweight blocks, generally several grooves are provided on the hub of the fan blade, and according to the test results of the balance detector, counterweight blocks are inserted into the corresponding grooves that need to increase the weight to improve the rotational balance of the fan blade. However, in this way, due to the different weight compensation situations, there is no fixed standard, and it is difficult to accurately prepare the counterweight blocks to correct the balance of the fan blade. Moreover, the size of the counterweight blocks needs to be accurately and closely fitted into the corresponding grooves. Otherwise, when the fan blade is working, the counterweight blocks are easily thrown out of the fan blade due to the centrifugal force of the fan blade rotation, thus losing the effect of balance correction. Moreover, the loose counterweight blocks may impact the components inside the equipment when being thrown out, posing a risk of equipment damage.
[0006] For the filling method, it is similar to the method of adding configuration blocks. For example, in the utility model patent with the publication number CN209414272U and the name "Balanced Soil Fixing Structure for Cooling Fan", annular equidistantly distributed filling grooves are provided at the "cover opening and / or cover surface" of the fan body. According to the test of the balance detector, the "unbalanced" position of the fan blade is determined, and the balance soil is filled into the filling grooves to correct the balance of the fan blade. However, in this way, the use of balance soil undoubtedly increases the production cost of the fan blade, and the amount of balance soil is not easy to control, the balance correction accuracy is relatively low, and when the fan blade is used, the balance soil is easily thrown out, unable to ensure the structural stability of the "uniform mass distribution" of the fan blade.
[0007] The glue-dotting method is a commonly used method at present. Generally, the "unbalanced" data of the fan blade is determined by the test of the balance detector, and glue-dotting operations are performed on one or more points at the "unbalanced" position of the fan blade, either on the magnetic ring of the fan blade or on the inner wall of the fan blade, to improve the rotational balance of the fan blade. However, in this way, first of all, after the glue solidifies, there may be a situation of weight change, and the amount of glue to be dotted is difficult to control. Moreover, some glues are easily loosened from the fan blade under the influence of environmental factors in some use scenarios (such as high-temperature environments), and are easily thrown out of the fan blade under the action of centrifugal force during the use of the fan blade, affecting the normal use of the fan blade.

[0019] The beneficial effects of the present invention are as follows: 1. Through the positioning ingot of the positioning and conveying unit, the workpiece to be processed is initially positioned, and the workpiece to be processed is moved to the loading station by the conveying linear module. Then, the moving unit sucks the workpiece to be processed at the loading station through the moving adsorption component and transfers it to the detection station of the balance detection unit. Subsequently, the balance detection unit detects the imbalance data of the workpiece to be processed and feeds back the detection result to the control unit. After the control unit obtains the imbalance data, through the moving adsorption component at the detection station, the workpiece to be processed is moved to the feeding table of the cutting and correction unit.

At the same time, it cooperates with the feeding lifting component to perform lifting adjustment on the workpiece to be processed to control the machining feed amount in the vertical direction of the workpiece to be processed during the correction cutting operation. 3. The design of the auxiliary positioning rod of the auxiliary positioning and lifting mechanism passing through the tool allows the workpiece to be processed to be placed on the auxiliary positioning rod, and the tool body effectively extends into the inner side of the workpiece to be processed. Then, through the correction and adjustment component, the tool body is moved to the position of the workpiece to be corrected. Subsequently, the cutting motor drives the tool body to rotate. At the same time, in cooperation with the blank feeding and lifting component, the workpiece is gradually lifted, so that the tool body cuts and corrects the magnet of the workpiece to be processed from the inside to the outside; 4. The setting of its cleaning unit can effectively clean the inner side of the workpiece after cutting. Through the wind force, the cutting waste or dust attached to the inner side of the workpiece is blown out to ensure the cleanliness of the inner side of the product and avoid the situation where the cutting waste or dust is synchronously magnetized and magnetically adheres to the inner side of the product and is difficult to clean when the workpiece is magnetized; 5. Since each process from balance detection, balance correction, wind cleaning to product magnetization is carried out on one device and shares the same set of detection data, the accuracy of correcting the unbalanced position of the product is effectively improved, the yield rate of the product is ensured, and at the same time, the structural stability of the product during daily rotation and use is also ensured after the workpiece balance is corrected.

The auxiliary positioning and lifting mechanism cooperates with the blank feeding and lifting assembly 54 to perform auxiliary positioning on the workpiece to be processed in the vertical direction, which not only ensures the accuracy of the cutting station set for the workpiece to be processed, but also ensures that the workpiece to be processed can be stably clamped during the correction cutting operation. At the same time, it cooperates with the blank feeding and lifting assembly 54 to adjust the lifting of the workpiece to be processed to control the machining feed amount in the vertical direction of the workpiece to be processed during the correction cutting operation; the cutting motor 533, the driving wheel 534, and the transmission belt 535 constitute a tool driving mechanism. The tool driving mechanism drives the cutting tool 531 to rotate during the correction cutting operation; it should be noted that the aforementioned cutting motor 533 is connected to the second support plate 528 through a motor seat 53e. At least one surface of the motor seat 53e is provided with a through hole (not shown), and the through hole is used to reserve a clearance position for the transmission belt 535.
[0057] Further, as shown in Figure 4 , 6 , FIGS. 10 - 17, the cutting tool 531 includes a rotating member 5311, a tool holder 5312 provided at one end of the rotating member 5311, and a tool body 5314 connected to one end of the tool holder 5312 through a fastening member 5313. The rotating member 5311 is used to be fixed to the equipment and drive the tool body 5314 to rotate. The tool holder 5312 is used to replace tool bodies 5314 of different specifications. The fastening member 5313 is used to load and unload the tool body 5314. The tool holder 5312, the tool body 5314, and the fastening member 5313 constitute a convenient replacement structure for the cutting tool 531; the aforementioned driving wheel 534 is provided at the other end of the rotating member 5311, and the driven wheel 532 is used to provide power for the rotating member 5311.
[0058] Among them, as shown in Figures 12-17As shown, the rotating member 5311 is composed of a rotating mounting base 5311a, a rotating shaft 5311e rotatably connected to the rotating mounting base 5311a through at least one rotating bearing 5311c, and a first locking member 5311d fixed to one end of the rotating mounting base 5311a. A limiting portion 5311f is provided at one end of the rotating shaft 5311e, and a sliding groove 5311h is formed inside the limiting portion 5311f. The sliding groove 5311h is used to cooperate with the rotating shaft 5311e to be rotatably connected to the rotating mounting base 5311a. A sliding protrusion 5311b is annularly provided at one end of the rotating mounting base 5311a corresponding to the sliding groove 5311h, and the sliding protrusion 5311b is slidably connected in the sliding groove 5311h. The driven wheel 532 is fixedly connected to one end of the rotating shaft 5311e corresponding to the first locking member 5311d, and the limiting portion 5311f is connected to the tool holder 5312.
[0059] As Figure 12 , 13 shown, the rotating bearings 5311c are respectively provided at both ends of the rotating shaft 5311e, and at least one first spacer 5315 is provided between the rotating bearings 5311c at both ends. A second spacer 5316 is further provided on the rotating bearing 5311c near the first locking member 5311d. The second spacer 5316 is used to form a gap between the first locking member 5311d and the driven wheel 532. The driven wheel 532 is mounted on the rotating shaft 5311e through at least one second locking member 5317. Among them, the setting of the rotating bearing 5311c can effectively support the rotating shaft 5311e in the rotating mounting base 5311a. At the same time, the rotating shaft 5311e is effectively centered in the rotating mounting base 5311a (that is, the central axis of the rotating shaft 5311e is basically coincident with the central axis of the rotating mounting base 5311a), ensuring that the rotational power of the rotating shaft 5311e can be normally output to the tool body 5314 to ensure the normal cutting effect of the tool body 5314 and avoid vibration or noise generated during rotation due to the inclined installation of the rotating shaft 5311e of the tool 531.
[0060] As Figure 12 , 16As shown in FIGS. 17, one end of the tool holder 5312 is provided with a positioning portion 5312a, which is fixedly connected to the limiting portion 5311f of the rotating shaft 5311e to form a detachable structure. A seat through hole 5312c is formed in the tool holder 5312 from one end face to the other end face. The tool body 5314 is fixed to the other end of the seat through hole 5312c of the tool holder 5312 through a tightening member 5313. An embedded edge 5311g is further provided inside the limiting portion 5311f of the rotating shaft 5311e. A fitting portion 5312b is protruded on the positioning portion 5312a corresponding to the embedded edge 5311g. The fitting portion 5312b is connected to the embedded edge 5311g to form a concave-convex mating connection structure. An internal thread 5312e (not shown) is provided inside the other end of the seat through hole 5312c of the tool holder 5312. An external thread 5313b (not shown) is provided at one end of the tightening member 5313. The external thread 5313b is fixedly connected to the internal thread 5312e. Among them, a shaped hole 5313a is provided in the middle of the tightening member 5313. At least one positioning pin 5312d is provided on the end face of the other end of the tool holder 5312. A positioning hole 531a is formed in the tool body 5314. The positioning hole 531a is sleeved on the positioning pin 5312d. It should be noted that the split design between the tool holder 5312 and the rotating shaft 5311e facilitates the installation of tool bodies 5314 of different models. During the processing, the user can replace the tool body 5314 suitable for processing according to the size of the workpiece to be processed. At the same time, the tool body 5314 and the tightening member 5313 cooperate and are connected to the tool holder 5312, also forming a detachable structure, which is convenient for the quick replacement of the tool body 5314 of the same model in daily use. The detachable design from the tool body 5314 to the tool holder 5312 effectively avoids the waste of resources caused by the operation of the need to replace the whole set of traditional cutting tools 531, making the replacement of the tool body 5314 easier and more convenient.
[0061] In addition, it should be noted that, as Figure 13 、 15 shown, the aforementioned rotating shaft 5311e is a tubular structure, which cooperates with the shaped hole 5313a of the tightening member 5313 and the seat through hole 5312c of the tool holder 5312, so that the middle part of the tool 531 of the present invention is a structure with both ends penetrating, leaving a clearance for the auxiliary positioning rod 539 to pass through the tool 531, so that the aforementioned "auxiliary positioning lifting mechanism" can better cooperate with the blanking lifting assembly 54 to "clamp" the workpiece to be processed. During the correction cutting operation, the auxiliary positioning rod 539 is in the state of passing through the tool 531. At this time, under the action of the correction adjustment assembly 52, the tool 531 adjusts the cutting position horizontally or longitudinally, and the auxiliary positioning rod 539 will not interfere with the horizontal adjustment of the tool 531.
[0062] During operation, the output end of the cutting motor 533 drives the driving wheel 534 to rotate. The driving wheel 534 drives the driven wheel 532 to rotate through the transmission belt 535. The rotating driven wheel 532 transmits power to the connected rotating shaft 5311e, driving the rotating shaft 5311e to rotate. At this time, the rotating shaft 5311e drives the tool holder 5312 to rotate, thereby driving the tool body 5314 connected to the tool holder 5312 to rotate, and cutting the inner side of the workpiece to be processed. Specifically, when correcting the fan blade, the rotating tool body 5314 performs a reduction micro-cutting on the inner side of the "unbalanced" position of the magnetic ring of the fan blade. Here, the feed rate of the cutting is calculated by the control unit 2 based on the "unbalanced" data measured by the balance detection unit 3, and is not limited here.
[0063] As Figure 4 , 7 , 8 shows, the blank feeding lifting assembly 54 includes a lifting bracket 541 connected to the correction base 51, at least two lifting guide rails 542 provided on one surface of the lifting bracket 541, a lifting plate 543 slidably connected to the lifting guide rails 542 through lifting sliders 54a, a blank feeding table 544 fixedly connected to the lifting plate 543, a pressing translation cylinder 545 installed on one side of the blank feeding table 544 through a pressing bracket 54b, a pressing vertical cylinder 546 provided at the output end of the pressing translation cylinder 545 through a pressing connecting plate 54c, a pressing member 547 fixed to the output end of the pressing vertical cylinder 546, a lifting cylinder 548 fixed to the bottom surface of the correction base 51 through a first mounting seat 54d, a connecting member 549 provided at the output end of the lifting cylinder 548, and at least one guide rod 54e provided on both sides of the connecting member 549. The pressing member 547 is used to cooperate with the pressing translation cylinder 545 and the pressing vertical cylinder 546 to limit the workpiece to be processed at the processing station on the blank feeding table 544. A tool hole 544a is provided on the blank feeding table 544, and the tool hole 544a is used to reserve an avoidance space for the cutting assembly 53 to correct the workpiece to be processed; wherein, each of the guide rods 54e is respectively passed through the correction bottom plate through a guide bushing 54f to form an extended end 54ea, and each of the extended ends 54ea is respectively clamped on both sides of the lifting plate 543. Connection cutouts 543a are provided at the positions where the lifting plate 543 is connected to the guide rods 54e on both sides, and clamping grooves 54eb connected to the connection cutouts 543a are respectively provided at the extended ends 54ea of each of the guide rods 54e.
[0064] The initial state of the cutting correction unit 5 is that the aforementioned positioning cylinder 53a is in the raised state, the auxiliary positioning rod 539 is raised by the positioning block 538, and the lifting cylinder 548 lowers the blanking table 544 to the machining position of the cutting tool 531. At this time, the upper end surface of the auxiliary positioning rod 539 is basically flush with the upper surface of the blanking table 544. During use, the moving unit 9 moves the workpiece to be machined from the balance detection unit 3 to the position of the tool hole 544a corresponding to the blanking table 544 of the blanking lifting assembly 54, and places the workpiece to be machined on the top end of the auxiliary positioning rod 539. At this time, the tool body 5314 of the cutting tool 531 is located inside the workpiece to be machined near the top surface. Then, the control unit 2 feeds the pressing vertical cylinder 546 above the workpiece to be machined through the pressing translation cylinder 545, and then drives the pressing vertical cylinder 546 to make the pressing member 547 press the workpiece to be machined. Then, according to the "unbalance" data recorded by the control unit 2, the cutting tool 531 is displaced to the inside of the position where the workpiece to be machined needs to be corrected through the cooperation of the first longitudinal slide rail 522 and the first horizontal linear module 525. Subsequently, the cutting motor 533 drives the driven wheel 532 to rotate through the cooperation of the transmission wheel 534 and the transmission belt 535. The rotating driven wheel 532 drives the rotating shaft 5311e to rotate, so as to drive the tool body 5314 provided on the rotating shaft 5311e to rotate. Then, in combination with the lifting cylinder 548 and the guide rod 54e, the lifting plate 543 is lifted to gradually raise the blanking table 544 connected to the lifting plate 543. The gradual rise of the blanking table 544 drives the workpiece to be machined to rise together. Furthermore, the tool body 5314 cuts and corrects the magnet of the workpiece to be machined from the inside to the outside. After the correction is completed, the lifting cylinder 548 cooperates with each guide rod 54e to raise the blanking table 544 on the lifting plate 543 to lift the corrected workpiece and move it away from the cutting tool 531. Then, the pressing vertical cylinder 546 and the pressing translation cylinder 545 are reset in sequence to drive the pressing member 547 to reset, and in cooperation with the moving unit 9, the corrected workpiece is moved to the cleaning unit 6. Subsequently, the blanking lifting assembly 54 is reset to receive the next workpiece to be machined and perform a cyclic correction operation.
[0065] As Figures 18-21As shown, the cleaning unit 6 is composed of a cleaning bracket 61 connected to the workbench 11, a blowing base 62 provided on the cleaning bracket 61, a dust collection hood 63 fixed to the blowing base 62, a blowing cross bar 64 erected between the blowing base 62 and the dust collection hood 63, a blowing positioning rod 65 penetrating through the blowing cross bar 64, a blowing member 66 installed on one side of the blowing cross bar 64, an upper cover 67 hinged to one side of the cleaning bracket 61 through a rotating rod 6a, a rotating cylinder 68 connected to one end of the rotating rod 6a, and a buffer 69 provided at the top of the other side of the cleaning bracket 61. The upper cover 67 is provided with a limit post 671 corresponding to the setting position of the blowing positioning rod 65. The blowing positioning rod 65 is used to place the workpiece after correction. At the same time, the workpiece on the blowing positioning rod 65 is fixed in cooperation with the limit post 671. Among them, the cleaning bracket 61 is connected to the workbench 11 through a cleaning adjustment plate 6b. The setting of the cleaning adjustment plate 6b facilitates the station adjustment of the cleaning unit 6 on the workbench 11. The output end of the rotating cylinder 68 is hinged to one end of the rotating rod 6a through a rotating hinge member 6c. The rotating cylinder 68 is connected to one side of the cleaning bracket 61 through a cylinder bracket 6d. A cleaning air path 64a is provided inside the blowing cross bar 64, and one end of the cleaning air path 64a is communicated with the blowing member 66. The aforementioned limit post 671 is connected to the upper cover 67 in cooperation with an embedding member 672, and the embedding member 672 locks the limit post 671 through a screw (not shown). The bottom of the aforementioned blowing base 62 is communicated with a discharge pipe 62a, and one end of the discharge pipe 62a is connected to a waste box (not shown). One end of the cleaning air path of the aforementioned blowing cross bar 64 is connected to a blowing device through a conduit (not shown). The blowing device preferably uses an air pump, and the blowing device can be selected according to the actual need for air flow power during the cleaning process of the equipment, and is not limited thereto here. In addition, a sealing ring 6e is provided around the bottom edge of the upper cover 67. The sealing ring 6e can effectively prevent gas from flowing out from the connection between the dust collection hood 63 and the upper cover 67, ensuring the cleaning effect of the cleaning unit 6 on the workpiece.
[0066] During operation, the control unit 3 controls the moving unit 9 to transfer the workpiece that has been cut and corrected to the air-blowing positioning rod 65 of the cleaning unit 6. Then, upon receiving an instruction from the control unit 3, the rotary cylinder 68 cooperates with the rotary hinge 6c to push up one end of the rotary rod 6a, causing the upper cover 67 to snap onto the upper opening of the dust collection hood 63. At this time, the limit post 671 installed on the upper cover 67 presses against the workpiece to be cleaned. Then, the control unit 3 activates the air-blowing device to deliver air flow to the air-blowing member 66 through a conduit. The air flow is output from the output end of the air-blowing member 66 to the inside of the workpiece to be cleaned, and the cutting waste / dust, etc. attached to the inside of the workpiece after corrected cutting is cleaned by means of wind cleaning. After cleaning, the air-blowing device stops working. At this time, the output end of the rotary cylinder 68 resets, drives the rotary rod 6a through the rotary hinge 6c to open the upper cover, and the moving unit 9 transfers the workpiece to the next working station.
[0067] As Figures 22-24 shown, the fine-tuning unit 7 includes a fine-tuning bottom plate 71 connected to the workbench 11, a lifting fine-tuning motor 72 installed on the bottom surface of the fine-tuning bottom plate 71, a first fine-tuning plate 73 fixed to the output end of the lifting fine-tuning motor 72, at least one horizontal fine-tuning guide rail 74 provided on the first fine-tuning plate 73, a second fine-tuning plate 75 slidably connected to the horizontal fine-tuning guide rail 74 through a first slider 7a, at least one vertical fine-tuning guide rail 76 installed on the second fine-tuning plate 75, and a fine-tuning panel 77 slidably connected to the vertical fine-tuning guide rail 76 through a second slider 7b. The aforementioned magnetizing mold 8 is provided on the fine-tuning panel 77. Among them, one side of the first fine-tuning plate 73 is provided with a horizontal fine-tuning motor 78, and the output end of the horizontal fine-tuning motor 78 is connected to the opposite side of the second fine-tuning plate 75 through a horizontal fine-tuning screw rod 7c. One side of the vertical fine-tuning guide rail 76 is provided with a vertical fine-tuning motor 79, and the output end of the vertical fine-tuning motor 79 is connected to the opposite side of the fine-tuning panel 77 through a vertical fine-tuning screw rod 7d. Among them, at least two plate adjustment holes 771 are respectively provided on both sides of the fine-tuning panel 77, and the plate adjustment holes 771 on the same side are connected to at least one adjustment limit strip 7e through adjustment screws. Each adjustment limit strip 7e is limited according to the size of the magnetizing mold 8. At least one size scale 772 is provided near the plate adjustment holes 771 on the fine-tuning panel 77, and the size scale 772 is used to cooperate with the width between the adjustment limit strips 7e. At least two fine-tuning linear bearings 731 are further provided on the bottom surface of the first fine-tuning plate 73, and each fine-tuning linear bearing 731 is respectively passed through the fine-tuning bottom plate 71 through a fine-tuning bushing 7f to ensure the smoothness of the lifting of the first fine-tuning plate 73. The output end of the lifting fine-tuning motor 72 passes through the middle of the first fine-tuning plate 73 and is fixedly connected to the middle of the first fine-tuning plate 73 through a fixing member 72a, and one end of the fixing member 72a clamps the output end of the lifting fine-tuning motor 72.
[0068] Further, as Figures 22-24As shown, both ends of the horizontal fine-tuning screw rod 7c are respectively connected to the first fine-tuning plate 73 and the second fine-tuning plate 75 through the horizontal screw rod seats 7ca, and the aforementioned horizontal fine-tuning motor 78 is installed on one of the horizontal screw rod seats 7ca; both ends of the vertical fine-tuning screw rod 7d are respectively connected to the second fine-tuning plate 75 and the fine-tuning panel 77 through the vertical screw rod seats 7da, and the aforementioned vertical fine-tuning motor 79 is installed on one of the vertical screw rod seats 7da.
[0069] Furthermore, as Figures 22-24 shown, one side of the fine-tuning bottom plate 71 is provided with a height limit sensor 711, and a height sensing piece 732 is provided on the side of the first fine-tuning plate 73 corresponding to the height limit sensor 711. The height sensing piece 732 is used to cooperate with the height limit sensor 711 for height adjustment and limit; a horizontal limit sensor 733 is provided on one side of the first fine-tuning plate 73, and a horizontal sensing piece 751 is provided on the side of the second fine-tuning plate 75 corresponding to the horizontal limit sensor 733. The horizontal sensing piece 751 is used to cooperate with the horizontal limit sensor 733 for horizontal displacement limit; a vertical limit sensor 752 is provided on one side of the second fine-tuning plate 75, and a vertical sensing piece 773 is provided on the side of the fine-tuning panel 77 corresponding to the vertical limit sensor 752. The vertical sensing piece 773 is used to cooperate with the vertical limit sensor 752 for vertical displacement limit.
[0070] Before the device works, it is necessary to first fine-tune and correct the magnetizing die 8 station through the fine-tuning unit 7. Specifically, according to the specifications of the workpiece to be magnetized, when the user needs to adjust the height of the magnetizing die 8, an instruction is sent to the lifting fine-tuning motor 72 through the control unit 3. The output end of the lifting fine-tuning motor 72 feeds towards the first fine-tuning plate 73. Under the guiding action of the cooperation between each fine-tuning linear bearing 731 and the fine-tuning bushing 7f, the first fine-tuning plate 73 rises and falls smoothly, causing the magnetizing die 8 provided on the fine-tuning panel 77 to rise and fall synchronously; furthermore, the height of the magnetizing die 8 is adjusted; when the user needs to adjust the lateral position of the magnetizing die 8, an instruction is sent to the lateral fine-tuning motor 78 through the control unit 3. The lateral fine-tuning motor 78 drives the connected lateral fine-tuning lead screw 7c to rotate. At the same time, with the design of the sliding structure of the lateral fine-tuning guide rails 74 and the first slider 7a provided on both sides of the first fine-tuning plate 73, the second fine-tuning plate 75 reciprocates horizontally in the X-axis direction of the present invention, and thus, the lateral position of the magnetizing die 8 is adjusted; when the user needs to adjust the longitudinal position of the magnetizing die 8, an instruction is sent to the longitudinal fine-tuning motor 79 through the control unit 3. The longitudinal fine-tuning motor 79 drives the connected longitudinal fine-tuning lead screw 7 to rotate. At the same time, with the design of the sliding structure of the horizontal and longitudinal fine-tuning guide rails 76 and the second slider 7b provided on both sides of the second fine-tuning plate 75, the fine-tuning panel 77 reciprocates longitudinally in the Y-axis direction of the present invention, and thus, the longitudinal position of the magnetizing die 8 is adjusted; in addition, it should be noted that the adjustment limit strips 7e provided on both sides of the surface of the fine-tuning panel 77 are connected to the plate adjustment holes in an adjustable manner through screws. By adjusting the distance between the two adjustment limit strips 7e, the size of the magnetizing die 8 can be matched, so as to clamp both sides of the magnetizing die 8, and then the magnetizing die 8 is limited between the two adjustment limit strips 7e; at the same time, in order to further stabilize the magnetizing die 8, locking screws can also be respectively locked to the magnetizing die 8 from the sides of the two adjustment limit strips 7e to further stabilize the magnetizing die 8; in the present invention, by adjusting the height position, lateral / longitudinal position of the fine-tuning unit 7, the magnetizing station of the magnetizing die 8 can be effectively adjusted to accurately match the magnetizing station of the workpiece to be magnetized conveyed by the moving unit 9, making the transfer position of the workpiece by the moving unit 9 more accurate and ensuring the effective connection of each processing link of the present invention.
[0071] As Figures 25-28As shown in the figure, the moving unit 9 is composed of a moving bracket 91 fixed on the workbench 11, at least one moving guide rail 92 provided on one side of the moving bracket 91, at least two moving adsorption components 93 slidably connected to the moving guide rail 92, a moving motor 94 provided on the other side of the moving bracket 91, a moving lead screw 95 installed at the output end of the moving motor 94, and a main transmission member 96 drivingly connected to the moving lead screw 95. The moving adsorption components 93 are drivingly connected to each other through a secondary transmission member 97. Among them, both ends of the moving lead screw 95 are respectively connected to the moving bracket 91 through moving lead screw seats 9a, the output end of the moving motor 94 is connected to one end of the moving lead screw 95 through a coupling 9b, and the main transmission member 96 is in threaded driving connection with the moving lead screw 95 through a lead screw nut 9c. At least two moving limit sensors 9d are respectively provided on the bottom surface of the moving bracket 91 through pads 9f. A moving sensing piece 9e is provided on the main transmission member 96 facing the side where the moving limit sensors 9d are arranged. The moving sensing piece 9e cooperates with the two moving limit sensors 9d to limit the reciprocating feed stroke of the main transmission member 96, so as to ensure the accuracy of the workpiece station switching to be processed, avoid the moving adsorption components 93 exceeding the stroke, and ensure the normal operation of the present invention.
[0072] Further, as Figures 25-28As shown, the movable adsorption assembly 93 includes a movable fixing plate 932 slidably connected to a movable guide rail 92 through a movable slider 931, a movable cylinder 933 mounted on the movable fixing plate 932, a mounting plate 934 provided at the output end of the movable cylinder 933, a vacuum shaft 936 fixed to one end of the mounting plate 934 through a mounting sleeve 935, a vacuum nozzle 938 connected to the vacuum shaft 936 through a suction member 937, and a limit sleeve 939 sleeved outside the vacuum nozzle 938. The vacuum shaft 936 is communicated with the suction member 937 and the vacuum nozzle 938, and the vacuum shaft 936 is connected to a vacuum gauge 93b through a conduit (not shown). Among them, each of the movable fixing plates 932 is respectively connected to a suction joint 93d through a first support member 93c. One end of the suction joint 93d is communicated with the vacuum shaft 936 through a conduit, and the other end of the suction joint 93d is mounted on the movable bracket 91 through a second support member 93e. The other end of the suction joint 93d is communicated with an air source member 93a through a conduit (not shown). The suction joint 93d is preferably a corrugated pipe joint (model M25). The air source member 93a is connected to a vacuum device (not shown) through a conduit (not shown). One end of the main transmission member 96 is fixedly connected to one of the movable fixing plates 932. Each of the movable adsorption assemblies 93 is respectively arranged corresponding to the processing stations of the positioning and conveying unit 4, the balance detection unit 3, the cutting and correction unit 5, the cleaning unit 6, and the fine adjustment unit 7. The movable motor 94, the movable lead screw 95, the lead screw nut 9c, and the main transmission member 96 constitute a movable driving mechanism, and the movable driving mechanism provides power for each of the movable adsorption assemblies 93 to reciprocate at each station of the positioning and conveying unit 4, the balance detection unit 3, the cutting and correction unit 5, the cleaning unit 6, and the fine adjustment unit 7. The mounting sleeve 935, the vacuum shaft 936, the suction member 937, the vacuum nozzle 938, and the limit sleeve 939 constitute a vacuum adsorption structure, and the vacuum adsorption structure cooperates with the vacuum device to perform vacuum adsorption on each workpiece when transferring the workpiece at each station. At the connection end of the vacuum shaft 936 and the suction member 937, a vacuum air path 936b is opened from outside to inside, and the vacuum air path 936b is communicated with the suction member 937. One end of the vacuum air path 936b is connected to the vacuum device through a conduit.
[0073] When the workpieces at each station need to be moved, the control unit 3 sends a movement instruction to the movement motor 94, and the movement motor 94 starts to work. At this time, the movement motor 94 drives the movement lead screw 95 to rotate through the coupling 9b. The rotating movement lead screw 95, in cooperation with the lead screw nut 9c, causes the main transmission member 96 and the movement lead screw 95 to reciprocate, thereby driving the movement adsorption assembly 93 connected to the main transmission member 96 to reciprocate. At this time, each movement adsorption assembly 93 linked by the auxiliary transmission member 97 moves along with the movement adsorption assembly 93 connected to the main transmission member 96. Each movement adsorption assembly 93 cooperates with the movement slider 931 to slide along the movement guide rail 92. When each movement adsorption assembly 93 slides to the corresponding station, the movement motor 94 pauses rotation, so that each movement adsorption assembly 93 is located above each station; then, the control unit 3 sends an instruction to each movement cylinder 933, so that the output ends of each movement cylinder 933 approach the workpieces at each station and come into contact with the workpieces. Then, the vacuum device is started, and the vacuum adsorption structure composed of the vacuum shaft 936, the suction member 937, and the vacuum nozzle 938 respectively performs vacuum adsorption on each workpiece at the corresponding position. Subsequently, each movement cylinder 933 resets, and the movement motor 94 restarts, moving each movement adsorption assembly 93 from the previous station to the next station. Then, the output ends of the movement cylinders 933 move vertically downward again, so that the workpieces adsorbed by each vacuum nozzle 938 approach the setting positions of the next station. Then, the vacuum device stops working, canceling the adsorption effect of each vacuum nozzle 938 on each workpiece, and placing each workpiece on the station. Finally, under the cooperation of the movement motor 94 and the movement lead screw 95, each movement adsorption assembly 93 resets, ready to suck the workpieces at the next batch of stations to be transferred. This process is repeated to achieve smooth connection between the positioning and conveying unit 4, the balance detection unit 3, the cutting and correction unit 5, the cleaning unit 6, and each station of the magnetization mold 8.
[0074] In addition, it should also be noted that one end of the vacuum shaft 936 is provided with an axis adjustment hole 936a, which cooperates with the mounting sleeve 935 to adjust the relative height position of the vacuum shaft 936 and the connected mounting sleeve 935 up and down to match the adsorption height requirements of workpieces to be processed with different specifications.
[0075] The present invention discloses a fan blade balance detection and correction device, which includes a positioning and conveying unit 4, a balance detection unit 3, a cutting and correction unit 4, a cleaning unit 6, and a magnetizing mold 8.
