Description

Technical Field

[0001] The present invention relates to the technical field of saw blade sorting, and in particular to a cylindrical wheel saw blade sorting device and a sorting method thereof. Background Art

[0002] Cylindrical wheels are usually used for grinding and thickness setting and flattening of cemented carbide, ceramics and stone. Cylindrical wheels are generally composed of a cylindrical wheel base, a saw blade and a cylindrical wheel cover. The saw blade is composed of a saw blade base and a cutter head. Regarding the production of cylindrical wheels, before the saw blade and the cylindrical wheel base are installed, the inner and outer circles of the saw blade base need to be precision-machined, and then the cutter head is welded to the outer surface of the saw blade base. The saw blade base with the cutter head is assembled on the cylindrical wheel base, and the saw blade base is tightly installed on the cylindrical wheel base with a cover plate, thereby forming a complete cylindrical wheel product. During the assembly process of this cylindrical wheel, the following two problems usually arise:

[0003] 1. When finishing the outer and inner rings of the saw blade base, the centering process of the saw blade base is usually carried out by manual experience, which will cause the inner and outer rings of the saw blade base to be non-concentric, resulting in a large deviation, that is, one side is larger and the other side is smaller, so that the saw blade base and the cylindrical wheel base cannot be tightly combined, and there are gaps and shaking problems. Therefore, it is easy to cause the saw blade base to break when the cylindrical wheel is used, and even cause workpiece fragments to fly out and injure people. Safety hazards;

[0004] 2. When welding the saw blade base and the cutter head, the saw blade base needs to be heated. Since the saw blade base is designed to be thin, the radial surface of the saw blade base is easily deformed during heating, which leads to gaps and inconsistent spacing between the saw blade bases after several subsequent saw blade bases are installed on the cylindrical wheel base. This can easily cause a large number of wear marks on the processed product caused by the cylindrical wheel, and such wear marks are difficult to eliminate.

[0005] In response to the above-mentioned problems in assembling and using cylindrical wheels, the current method is mainly to arrange production quality inspectors to use conventional tools to detect the concentricity and flatness of the saw blade base to eliminate the safety hazards during the processing and use of the cylindrical wheel. However, it is difficult to inspect every saw blade through manual inspection, and the inspection cost is high, the efficiency is low, and the inspection effect is not ideal. Due to the high cost, low efficiency and unguaranteed inspection quality of manual inspection, some inspection instruments have been launched on the market. Among them, regarding the concentricity detection of the saw blade base, the coordinate detection method is currently more commonly used in the market. It first measures the outer circle coordinates and inner circle coordinates of the sample, and then calculates the center of the outer circle and inner circle through a formula, and then calculates the center difference of the outer circle and inner circle, and then determines the concentricity value of the sample. However, this concentricity detection method requires cumbersome inspection procedures and calculation processes, and the operation is relatively complicated, which will increase the production cost of the sorting equipment.

[0006] Regarding the flatness detection of the saw blade base, some flatness detectors are currently used to detect the flatness of the saw blade base. For example, the Chinese invention patent with publication number CN109317752A and patent name "A Process for Processing Cold Saw Blades" mentions in its process steps the use of a flatness measuring instrument to detect the flatness of the saw blade base and record the flatness data. Usually, this flatness measuring instrument uses an optical projection method, and its measurement accuracy is relatively low, only reaching about 0.1mm. In order to improve the measurement accuracy, manual calibration is required later, so it still costs a lot of labor costs and lacks automation.

[0007] Regarding the impact strength test of the cutter head, there is still a lack of more targeted testing equipment on the market. There are only testing equipment for the welding strength of the cutter head. For example, the Chinese utility model patent with the announcement number CN209690077U and the patent name "A Saw Blade Cutter Head Welding Strength Testing Device" discloses a pressure mechanism, which includes an extrusion cutter head, a roller, a slide rod and a driving member; when working, the roller is facing the saw blade cutter head, and then continuously pressurizes the cutter head. When the cutter head breaks, the pressure value at this time is recorded to obtain the welding strength of the cutter head; and after each cutter head is tested, it is necessary to rotate and replace the next cutter head to be tested, and the detection efficiency is relatively low. It can be seen that the detection of the welding strength of this cutter head requires slow force to be applied to the cutter head, and the force value is constantly increasing. This detection method is only suitable for detecting the welding strength tolerance range of the cutter head, and is not suitable for the impact strength detection of the cutter head, because the impact strength detection of the cutter head requires a certain initial speed and a constant force.

[0008] Therefore, there is an urgent need in the market for a sorting device that can automatically and specifically detect the concentricity, flatness and impact resistance of the saw blade base. Summary of the invention

[0022] Furthermore, the second inspection station is provided with a second inspection bracket, and the stamping assembly and the second vision module are installed above the second inspection station through the second inspection bracket.

[0023] Furthermore, the cylindrical wheel saw blade sorting equipment also includes a grabbing device, which is arranged above the conveying system, the second inspection station and the collection station through a slide rail bracket; the grabbing device has a grabbing drive and an electromagnetic gripper, and the grabbing drive, electromagnetic gripper, and grabbing positioning module are electrically connected to the main control system. The grabbing drive drives the electromagnetic gripper to slide along the slide rail bracket to the second inspection station to grab the saw blades that pass the impact resistance test into the good product box of the collection station, and grab the saw blades that fail the impact resistance test into the recycling box of the collection station.

[0024] Furthermore, the cylindrical wheel saw blade sorting equipment also includes a defective product separating device, which is arranged above the defective product box. The defective product separating device has a separating table and an electromagnetic heating module. The electromagnetic heating module is electrically connected to the main control system.

A conveying positioning module is arranged along the direction of the conveyor belt and corresponding to the first inspection station, the second inspection station and the collection station. The conveying positioning module is electrically connected to the main control system.

[0026] In order to overcome the deficiencies of the prior art, a second object of the present invention is to provide a method for sorting cylindrical wheel saw blades.

[0027] The second object of the present invention is achieved by adopting the following technical solution: a cylindrical wheel saw blade sorting method, using the cylindrical wheel saw blade sorting device to sort the cylindrical wheel saw blades, comprising the following steps:

[0028] S1, vibrating the saw blades to be sorted to the conveying system by vibration;

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) The embodiment of the present application provides a cylindrical wheel saw blade sorting device, which is provided with a first detection station, a second detection station and a collection station along the conveying direction of the saw blade, and a detection system and a collection box are correspondingly provided at each station; wherein, the concentricity of the saw blade base is automatically detected by the concentricity detection system. Compared with the previous implementation method relying on manual detection and calculation of the outer circle and inner circle coordinate formula, the embodiment of the present application can avoid the cumbersome detection process and the process of configuring an expensive computing system for calculation while maintaining the full-process automated concentricity detection, thereby reducing the equipment manufacturing cost, and making the saw blade base and the cylindrical wheel base more tightly and compactly assembled, thereby avoiding the saw blade base from breaking;

[0033] Then, the cutter heads on the saw blade base that have passed the concentricity test are tested for impact resistance, so that the impact resistance test system applies a set pressure to all the cutter heads on the saw blade base at a certain initial speed and at a set pressure for impact resistance test, thereby realizing automated detection of the impact resistance of the cutter heads, and the cutter heads on the entire saw blade base can be tested for impact resistance at one time, which improves the detection efficiency by at least 150% compared with previous manual detection, and classifies the saw blades into defective, good, and recyclable products based on the test results; thereby realizing full automation to test each saw blade, improving the sorting efficiency by at least 3 times, saving a lot of labor, time and equipment production costs, achieving 100% missed detection, and achieving high detection quality, avoiding the problem of saw blade breakage and injury, and meeting the supply demand of cylindrical wheels.

[0034] (2) The plane detection system arranged on the first detection station performs flatness detection on the saw blade base through the distance detection module, automatically sorts out the saw blade bases with qualified flatness, and judges whether the axial assembly of several saw blade bases is tightly assembled when several saw blade bases are mounted together on the cylindrical wheel base, so as to avoid assembly gaps and shaking between several saw blade bases, thereby further improving the compactness of the assembly of the saw blade base and the cylindrical wheel base, and preventing the problem of grinding marks and saw blade breaking and flying out to injure people due to the deformation of the saw blade base during the processing of the cylindrical wheel; compared with the conventional flatness measuring instrument using conventional optical projection and manual correction detection means in the past, the detection accuracy of the embodiment of the present application can reach 0.03mm, which is higher, and further improves the assembly accuracy, service life and processing quality of the cylindrical wheel.

[0035] (3) By setting up several grabbing devices on the slide rail bracket, it is possible to automatically grab the defective, recyclable and good cylindrical wheels in the conveying system, the second inspection station and the collection station and put them into the corresponding collection boxes, so as to realize the fully automated classification and collection of cylindrical wheels, with a high degree of intelligence, saving costs and improving work efficiency.

[0036] (4) A defective product separation device is arranged behind the first inspection station. The electromagnetic induction coil of the defective product separation device heats the saw blade base grasped by the grasping device on the separation table, thereby separating the cutter head from the saw blade base, thereby realizing automatic heating separation between the saw blade base and the cutter head, saving labor costs. In addition, the electromagnetic induction coil can simultaneously heat and separate several cutter heads around the saw blade base, thereby achieving high separation efficiency.

[0037] (5) By providing a sorting method for sorting cylindrical wheel saw blades using sorting equipment, the automatic feeding, transmission, concentricity detection, flatness detection, impact strength detection and classification collection of saw blades can be realized. The whole process is automated to ensure the inspection quality of saw blades, reduce labor costs and improve sorting work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0059] like Figure 1-9 As shown, a cylindrical wheel saw blade sorting device is used for detecting the concentricity deviation between the outer circle axis c12 and the inner circle axis c14 of the saw blade base c1 in the cylindrical wheel a, for detecting the flatness deviation of the circumferential surface of the saw blade base c1, and for detecting the impact strength of the cutter head c2 on the saw blade base c1.

[0060] The sorted cylindrical wheel a is mainly used for grinding and thickness shaving of hard alloy, ceramics and stone. The cylindrical wheel a has a cylindrical wheel base b, a saw blade c and a cylindrical wheel cover d. The saw blade c is composed of a saw blade base c1 and a cutter head c2 welded to the outer periphery of the saw blade base c1. First, a number of orderly arranged cutter heads c2 are welded to the outer periphery of the saw blade base c1, and then the saw blade base c1 with the cutter heads c2 welded is sleeved on the cylindrical wheel base b, and finally the cylindrical wheel cover d is locked on one end of the cylindrical wheel base b to prevent the saw blade base c1 from sliding off the cylindrical wheel base b.

[0061] The cylindrical wheel saw blade sorting equipment includes a frame 10, a control cabinet 15, a feeding system 21, a conveying system 30, a concentric detection system 41, a plane detection system 42, an impact resistance detection system 51, a main control system 70, a gripping device 80, a defective product separation device 90, a good product box 61, a recycling box 62 and a defective product box 63. The extension direction of the frame 10 is set to the conveying direction of the saw blade c. The control cabinet 15 is set on one side of the frame 10. The main control system 70 and electrical control components such as a power module 72 that provides power to the main control system 70 are installed in the control cabinet 15. A feeding station 20, a first detection station 40, a separation station, a second detection station 50 and a collection station 60 are set along the conveying direction of the saw blade c.

[0062] The feeding station 20 is provided with a feeding system 21, which has a feeding tray 211 and a feeding motor. The feeding tray 211 is provided at the feeding end of the conveying system 30, and the feeding tray 211 has a tendency to be tilted toward the conveying system 30. The feeding motor is installed on the feeding tray 211 and is electrically connected to the main control system 70. After the feeding motor is started, the feeding tray 211 is vibrated, so that the saw blade c in the feeding tray 211 gradually slides toward the conveying system 30 along the tilting direction of the feeding tray 211 under the vibration force, and then the saw blade c to be sorted is vibrated and fed to the conveying system 30. In addition, baffles are provided on both sides of the feeding tray 211 to prevent the saw blade c from deviating during the vibration feeding process.

[0063] The conveying system 30 comprises a transmission shaft 301, a conveyor belt 302 and a conveying motor (not shown in the figure). The conveyor belt 302 is movably mounted on the frame 10 along the conveying direction through a plurality of transmission shafts 301. The conveying motor is arranged on the frame 10 to drive the conveyor belt 302 to convey the saw blade c. Therefore, the saw blade c to be sorted is conveyed to the first detection station 40, the second detection station 50 and the collection station 60 through the conveyor belt 302. In order to accurately convey the saw blade c to the corresponding station, a conveying positioning module (not shown in the figure) is correspondingly arranged along the conveying direction of the conveyor belt 302. The conveying positioning module is electrically connected to the main control system 70. The conveying positioning module receives the instruction of the main control system 70 and feeds back a signal to the conveying motor to start or stop the conveying action of the conveyor belt 302.

[0064] The collecting stations 60 are arranged in a number along the conveying direction. Specifically, the collecting station 60 arranged after the first inspection station 40 is used to place a defective box 63 for collecting defective saw blades c, so the disassembly station is correspondingly arranged near the defective box 63; the collecting station 60 arranged after the second inspection station 50 is used to place a recycling box 62 for collecting recyclable and repairable saw blades c; the collecting station 60 arranged at the end of the conveyor belt 302 is used to collect a good box 61 for collecting good saw blades c.

[0065] Therefore, by arranging the collection stations 60 and the boxes along the conveying direction, the corresponding saw blades c can be automatically classified and collected accurately and orderly, thereby reducing the labor intensity of workers and improving production efficiency.

[0066] The first detection station 40 is provided with a first detection bracket 11 and an annular mounting bracket 12. The first detection bracket 11 is arranged on one side of the frame 10, and the annular mounting bracket 12 is fixedly mounted on the first detection bracket 11 and located above the conveyor belt 302. The annular mounting bracket 12 has an annular mounting portion 121 and a central mounting portion 122 arranged at the annular center position of the annular mounting portion 121.

[0067] The annular mounting frame 12 is provided with a concentric detection system 41, which has a first visual module 411, which is electrically connected to the main control system 70, and receives instructions from the main control system 70 to perform image shooting and image analysis. The first visual module 411 is installed in the central mounting portion 122 at the center of the annular mounting frame 12, and the saw blade c to be sorted is transmitted to the first detection station 40 through the conveyor belt 302, and combined with the precise positioning signal feedback of the transmission positioning module, the saw blade c can be accurately positioned and transmitted to the bottom of the annular mounting frame 12.

[0068] In this way, the first visual module 411 can shoot the saw blade c from top to bottom to obtain a saw blade image, and then analyze the saw blade outer circle c11 and the saw blade inner circle c13 of the saw blade base c1 in combination with the saw blade image, determine the outer circle axis c12 of the saw blade outer circle c11 and the inner circle axis c14 of the saw blade inner circle c13, and analyze the distance difference between the outer circle axis c12 and the inner circle axis c14 (that is, the concentricity deviation data). The first visual module 411 sends the obtained concentricity deviation data to the main control system 70.

[0069] The main control system 70 transmits the concentricity deviation data to the data processing module 71, and the data processing module 71 compares the concentricity deviation data of the saw blade base c1 with the pre-stored standard parameters. If the concentricity deviation data is within the range of the standard parameters, the concentricity test of the saw blade base c1 is judged to be qualified, and a qualified signal is fed back to the main control system 70, and the main control system 70 sends a command to control the conveyor belt 302 to transport the saw blade c to the second inspection station 50.

[0070] Otherwise, the main control system 70 sends an instruction to control the grabbing device 80 to grab the saw blade c into the defective box 63. Since the concentricity test of the saw blade base c1 fails, the saw blade base c1 of the saw blade c has no value for recycling and repair, and the cutter head c2 can be recycled, so it is directly grabbed into the defective box 63.

[0071] Therefore, by setting a concentricity detection system 41 at the first detection station 40, the concentricity detection system 41 automatically detects the concentricity of the saw blade base c1 of the saw blade c transmitted to the first detection station 40 through the first visual module 411, realizes the concentricity deviation analysis of the saw blade base c1, and automatically sorts out the saw blade base c1 with qualified concentricity. Then, it is judged whether the saw blade base c1 and the cylindrical wheel base b are tightly assembled, and the assembly gap and shaking between the saw blade base c1 and the cylindrical wheel base b are avoided, so as to prevent the saw blade c from producing grinding marks due to the deformation of the saw blade during the processing, and even the problem of the saw blade base c1 breaking and the workpiece flying out and injuring people.

[0072] Moreover, compared with the previous method of relying on manual inspection by production quality inspectors and the implementation of outer circle and inner circle coordinate formula calculation, it is possible to avoid cumbersome inspection procedures and the process of configuring expensive computing systems for calculations while maintaining full-process automated concentricity detection, thereby reducing equipment production costs and making the saw blade base c1 and the cylindrical wheel base b more tightly and compactly assembled, avoiding breakage of the saw blade base c1 and improving the overall assembly accuracy, service life and processing quality of the cylindrical wheel a.

[0073] Preferably, a plane detection system 42 is provided on the first detection station 40, so as to detect the flatness of the radial surface of the saw blade base c1 through the plane detection system 42, and then sort out the saw blade base c1 with the flatness meeting the requirements. The saw blade base c1 with qualified flatness can further improve the overall assembly accuracy of the cylindrical wheel a, and then improve the service life and processing quality of the cylindrical wheel a.

[0074] The plane detection system 42 has a plurality of distance detection modules 421, and the distance detection modules 421 are electrically connected to the main control system 70. The distance detection modules 421 are arranged along the circumferential direction of the annular mounting portion 121 of the annular mounting frame 12. When the saw blade c to be sorted is conveyed to the first detection station 40 through the conveyor belt 302 for concentricity detection, the main control system 70 will also send an instruction to start the distance detection module 421.

[0075] The distance detection module 421 of the embodiment of the present application uses a laser distance probe, so that several distance detection modules 421 on the annular mounting frame 12 simultaneously project light to different positions of the radial surface of the saw blade base c1, so as to obtain the flatness deviation data of different positions of the radial surface of the saw blade base c1, and then the distance detection module 421 sends the obtained flatness deviation data to the main control system 70.

[0076] The main control system 70 transmits the flatness deviation data to the data processing module 71, and the data processing module 71 compares the flatness deviation data with the pre-stored standard parameters. If the flatness deviation data is within the range of the standard parameters, it is determined that the plane detection of the saw blade base c1 is qualified, and a qualified signal is fed back to the main control system 70, and the main control system 70 sends an instruction to control the conveyor belt 302 to transport the saw blade c to the second detection station 50.

[0077] Otherwise, the main control system 70 sends an instruction to control the grabbing device 80 to grab the saw blade c into the defective box 63. Since the saw blade c that fails the flatness test has no value for recovery and repair, it is directly grabbed into the defective box 63.

[0078] The flatness detection of the saw blade base c1 by the distance detection module 421 is further described as follows:

[0079] When using the distance detection module 421 to obtain the flatness deviation data of different positions of the radial surface of the saw blade base c1 by projecting light, it is necessary to pre-adjust to the horizontality of the plane detection system 42 and the conveyor belt 302. At this time, the side of the saw blade base c1 that contacts the conveyor belt 302 can be used as the reference surface, that is, the distance between the surface of the conveyor belt 302 and the distance detection module 421 is used as the reference distance data. Then, the distance detection module 421 projects light to different positions of the radial surface of the saw blade base c1, and the time taken for the light to be emitted to the radial surface of the saw blade base c1 and the light to be reflected back is calculated, and then the distance from the distance detection module 421 to the radial surface of the saw blade base c1 is calculated.

[0080] Then, the distance detection module 421 obtains the detection distance data on the radial surface of the saw blade base c1 and subtracts it from the reference distance data to obtain a difference. If the average difference (that is, the flatness deviation data) obtained by the distance detection module 421 at different positions on the radial surface of the saw blade base c1 is within the range of the standard parameters pre-stored in the data processing module, it is judged that the flatness detection of the saw blade base c1 is qualified.

[0081] Therefore, a plane detection system 42 is set at the first detection station 40. The plane detection system 42 performs flatness detection on the saw blade base c1 of the saw blade c through the distance detection module 421, and automatically sorts out the saw blade base c1 with qualified flatness. Then, it is judged whether the axial assembly of several saw blades is tightly assembled when several saw blades are sleeved together on the cylindrical wheel base b, and the assembly gap and shaking between several saw blades are avoided, thereby further improving the assembly compactness of the saw blade base c1 and the cylindrical wheel base b, and preventing the cylindrical wheel a from producing grinding marks due to the deformation of the saw blade base c1 and the saw blade c breaking and flying out to hurt people during the processing; compared with the conventional optical projection flatness measuring instrument and manual correction detection means in the past, the detection accuracy of the embodiment of the present application can reach 0.03mm, which is higher, and further improves the assembly accuracy, service life and processing quality of the cylindrical wheel.

[0082] The second detection station 50 is provided with a second detection bracket 13 and a detection table 513, and the second detection bracket 13 and the detection table 513 are arranged on one side of the frame 10. The second detection bracket 13 is equipped with an anti-impact detection system 51, which has a stamping assembly 511, a second visual module 512, a stamping probe, a lifting gear 514 and a lifting rack 515. The stamping assembly 511 has a stamping motor 5111, an annular tool holder 5112 and a plurality of stamping heads 5110 arranged along the bottom of the annular tool holder 5112. The stamping motor 5111 is installed on the second detection bracket 13, and the output shaft of the stamping motor 5111 is connected to the lifting gear 514. The lifting rack 515 is movably installed on the vertically arranged slide groove of the second detection bracket 13, and the lifting rack 515 is in transmission engagement with the lifting gear 514.

[0083] The punching motor 5111 is electrically connected to the main control system 70. Under the control of the main control system 70, the punching motor 5111 is started to drive the lifting gear 514 to rotate, and then the lifting rack 515 is driven to perform vertical lifting. The annular tool holder 5112 is fixedly mounted on the lifting rack 515. When the punching motor 5111 drives the lifting rack 515 to descend vertically, the annular tool holder 5112 and a plurality of punching heads 5110 on the annular tool holder 5112 can be synchronously driven. The annular tool holder 5112 can be disassembled from the lifting rack 515, so as to replace the annular tool holder 5112 with a different number of punching heads 5110. The number of punching heads 5110 of the replaced annular tool holder 5112 can be selected according to the number of blades c2 of the current saw blade c. Typically, the number of blade heads c2 of the saw blade c is 11-13, so the number of punching heads 5110 of the annular tool holder 5112 that needs to be replaced is also selected to be 11, 12 or 13 accordingly.

[0084] When the conveyor belt 302 conveys the saw blade c to the vicinity of the second inspection station 50, the conveyor positioning module feeds back a positioning signal to the main control system 70, and the main control system 70 sends a command to the gripping device 80 to grip the saw blade c to the inspection table 513 of the second inspection station 50, and then the gripping device 80 resets back to the top of the conveyor belt to wait for the next saw blade c. The inspection table 513 is adapted to the inner circular hole of the saw blade c to fix the saw blade c, providing a stable condition for the impact strength test of the cutter head c2 of the saw blade c.

[0085] It should be noted that in order to prevent the annular tool holder 5112 from hindering the grasping device from grasping the saw blade c to be tested onto the testing table 513, an avoidance slide rail 516 is provided on the second testing bracket 13, which is used to slide the stamping assembly 511, the lifting gear 514 and the lifting rack 515 together on the avoidance slide rail 516 through a slider to one end close to the conveyor belt 302, so that the grasping device 80 can slide from above to grasp the saw blade c to be tested onto the testing table 513, and then the stamping assembly 511, the lifting gear 514 and the lifting rack 515 slide and reset along the avoidance slide rail 516 to test the impact resistance of the saw blade c.

[0086] The stamping probe arranged on the second detection bracket 13 detects that there is a saw blade c on the detection table 513, and feeds back a signal to the main control system 70, so that the main control system 70 controls the stamping motor 5111 to drive the lifting rack 515, driving the annular tool holder 5112 and its several stamping heads 5110 to vertically descend and apply a set vertical downward pressure to all the blade heads c2 of the saw blade c on the detection table 513 one by one, so that the annular tool holder 5112 and its blade heads c2 only need to descend once to simultaneously perform all pressure-applied impact resistance tests on all the blade heads c2 of the current saw blade c, which greatly improves the efficiency of detecting the impact resistance of the blade heads c2 of the saw blade c.

[0087] The set pressure value provided in the embodiment of the present application is 30-45N. The embodiment of the present application preferably sets the set pressure value of the punch head 5110 to 40N. The specific set pressure value can be adjusted accordingly according to the material formula of the cutter head c2. The thickness of the cutter head c2 welded on each saw blade base c1 is usually within the range of 5-6mm. Therefore, as long as the cutter head cannot withstand the stamping of the set pressure, it will completely break and fall off.

[0088] During the process of the punch head 5110 applying a set pressure to the cutter head c2 on the saw blade base c1, the second visual module 512 installed on the second detection bracket 13 is also electrically connected to the main control system 70. The second visual module 512 takes a picture of the cutter head c2 according to the instruction of the main control system 70, and then analyzes the impact resistance information of whether the cutter head c2 is broken in combination with the picture of the cutter head c2. The second visual module 512 sends the obtained impact resistance information to the main control system 70.

[0089] The main control system 70 transmits the impact resistance information to the data processing module 71, and the data processing module 71 compares the impact resistance information with the pre-stored standard parameters. If the cutter head c2 is not broken under the set pressure impact, it is judged that the cutter head c2 has passed the impact resistance test, and the qualified signal is fed back to the main control system 70. The main control system 70 sends an instruction to control the grabbing device 80 to grab the saw blade c onto the conveyor belt 302, and the conveyor belt 302 transports the saw blade c to the good product box 61. Otherwise, the main control system 70 sends an instruction to control the grabbing device 80 to grab the saw blade c to the recycling box 62, so that the broken saw blade c of the cutter head c2 can be repaired and reused later.

[0090] Therefore, an impact resistance detection system 51 is set at the second detection station 50. The impact resistance detection system 51 drives the punch head 5110 through the punch motor 5111 to vertically apply a set pressure to the cutter head c2 on the saw blade c on the detection table 513, and controls the second visual module 512 to analyze and the data processing module 71 to compare through the main control system 70, so as to automatically detect the impact resistance of the cutter head c2. Then, it is determined whether the cutter head c2 breaks under the set pressure, so as to avoid the problem of the cutter head c2 breaking and flying out to hurt people during the daily grinding, thickness setting and flattening of the saw blade c, further ensuring the processing safety, and automatic detection, saving a lot of labor costs, and uniform detection quality.

[0091] In this way, the impact resistance of the cutter head c2 on the saw blade base c1 that has passed the concentricity test is tested, so that the impact resistance testing system applies pressure to all the cutter heads c2 on the saw blade base c1 at a certain initial speed and at a set pressure to perform impact resistance testing, thereby realizing automatic testing of the impact resistance of the cutter head c2, and the impact resistance of the cutter head c2 of the entire saw blade base c1 can be tested at one time, which improves the detection efficiency by at least 150% compared with the previous manual detection, and classifies the saw blades into defective, good and recyclable products according to the detection results; realizes full automation to detect each saw blade c, improves the sorting efficiency by at least 3 times, saves a lot of labor, time and equipment production costs, achieves 100% of the missed detection effect, improves the detection quality, avoids the problem of saw blade base c1 and cutter head c2 breaking and flying out to injure people during saw blade c processing, and meets the supply demand of cylindrical wheel a.

[0092] Slide rails are correspondingly installed on the second inspection station 50 and the collection station 60 on both sides of the frame 10 and in the conveying direction, and a plurality of grabbing devices 80 are installed on the slide rail bracket 14, so that the grabbing devices 80 can be installed above the conveying system 30, the second inspection station 50 and the collection station 60.

[0093] The grabbing device 80 has a grabbing driver, an electromagnetic gripper 801, a grabbing positioning module and a driving connecting rod 804. The grabbing driver includes a grabbing motor 802 and a sliding motor 803. The grabbing motor 802, the sliding motor 803, the electromagnetic gripper 801, the grabbing positioning module and the driving connecting rod 804 are all electrically connected to the main control system 70. The grabbing motor 802 is slidably mounted on the slide rail bracket 14 through a slide seat. The grabbing motor 802 is vertically arranged downward with an output shaft. The driving connecting rod 804 is arranged on the output shaft of the grabbing motor 802. The electromagnetic gripper 801 is installed at the lower end of the driving connecting rod 804. The grabbing positioning module is arranged on the slide seat on which the grabbing motor 802 is installed.

[0094] Under the control of the main control system 70, the grabbing motor 802 slides along the slide rail bracket 14 under the control of the main control system 70, and the specific sliding position of the grabbing motor 802 is captured by the grabbing positioning module, and the positioning signal is fed back to the main control system 70 to control the grabbing motor 802 to reach the designated work position, and the driving connecting rod 804 is used to drive the electromagnetic gripper 801 to rise and fall vertically. Since the saw blade c is made of iron material, when the driving rod drives the electromagnetic gripper 801 to descend, the electromagnetic gripper 801 magnetically attracts and releases the saw blade c by powering on or off. Then the grabbing motor 802 can control the driving connecting rod 804 and the electromagnetic gripper 801 to rotate, so as to adjust the rotation angle of the saw blade c, which is especially convenient for the saw blade c to switch to the next cutter head c2 when the impact strength of the cutter head c2 is being tested.

[0095] Therefore, by setting a plurality of grabbing devices 80 on the slide rail bracket 14, it is convenient to automatically grab the defective, recyclable and good saw blades c in the conveying system 30, the second inspection station 50 and the collection station 60 and put them into the corresponding collection boxes. For example, the grabbing device 80 slides to the conveying system 30 behind the first inspection station 40 to grab the saw blades c that fail the concentricity test or the flatness test to the defective box 63 of the collection station 60, and the grabbing device 80 slides to the second inspection station 50 to grab the saw blades c that fail the impact resistance test to the recycling box 62 of the collection station 60 or grab the saw blades c that pass the impact resistance test to the good box 61 of the collection station 60. The saw blades c are fully automatically classified and collected, with a high degree of intelligence, cost savings and improved work efficiency.

[0096] The frame 10 and the sliding bracket are fixedly connected to each other by a crossbeam and a defective product separating device 90 is arranged above the defective product box 63. The defective product separating device 90 has a separating table 901 and an electromagnetic heating module. The electromagnetic heating module includes an electromagnetic heating power supply 902 and an electromagnetic induction coil 903. The electromagnetic heating power supply 902 and the electromagnetic induction coil 903 are both electrically connected to the main control system 70.

[0097] Under the control of the main control system 70, the grabbing device 80 grabs the saw blade c that fails the concentricity test or the flatness test to the disassembly table 901, and the electromagnetic induction coil 903 is arranged around the disassembly table 901. The electromagnetic heating power supply 902 energizes the electromagnetic induction coil 903, and the electromagnetic induction coil 903 is energized to perform electromagnetic heating to heat and dissolve the flux of the saw blade c, thereby separating the cutter head c2 from the saw blade base c1 and collecting them in the defective box 63. Specifically, the grabbing device 80 or the manipulator can grab the cutter head c2 and the saw blade base c1 into the defective box 63. Since the saw blade base c1 fails the concentricity or flatness test, it has no recycling value and can be sold as scrap, while the cutter head c2 can be recycled.

[0098] Therefore, a defective product separation device 90 is set behind the first inspection station 40. The saw blade grabbed by the grabbing device 80 on the separation table 901 is heated by the electromagnetic induction coil 903 of the defective product separation device 90, so that the cutter head c2 is separated from the saw blade base c1, thereby realizing automatic heating and separation between the saw blade base c1 and the cutter head c2, saving labor costs, and the electromagnetic induction coil 903 can simultaneously heat and separate several cutter heads c2 around the saw blade base c1, and the separation efficiency is high.

[0099] The embodiment of the present application provides a cylindrical wheel saw blade sorting method, which uses the cylindrical wheel saw blade sorting device to sort the cylindrical wheel saw blades, including the following steps:

[0102] S3, the conveying system 30 conveys the saw blade c that has passed the concentricity test of the saw blade base c1 in step S2 to the second inspection station 50; applies a set pressure to the cutter head c2 on the saw blade base c1 through the impact resistance detection system 51 of the second inspection station 50 to obtain the impact resistance information of the cutter head c2; and sends the obtained impact resistance information to the main control system 70 and compares it with the standard parameters of the data processing module 71; if the cutter head c2 does not break under the impact of the set pressure, it is judged that the impact resistance test of the cutter head c2 is qualified, and it is conveyed to the good product box 61 of the collection station 60; otherwise, the saw blade c is grabbed into the recycling box 62 of the collection station 60.

[0103] In this way, by providing the above cylindrical wheel saw blade sorting method, the automatic feeding, transmission, concentricity detection, flatness detection, impact strength detection and classification collection of the saw blade c can be realized, and the whole process can be automated to ensure the inspection quality of the saw blade c, reduce labor costs and improve sorting work efficiency.

[0104] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
