Description

Technical Field

[0001] This invention belongs to the technical field of saw blade production equipment, and relates to a fully automated grinding production line for large saw blades. Background Technology

[0002] A grinding machine is a machine tool used for grinding the surface of a workpiece and is widely used in the machining industry. Existing grinding machines typically include a worktable, a grinding wheel, a motor, and a workpiece fixing device. The workpiece fixing device is located on the worktable at one end of the grinding wheel's friction surface. During use, the workpiece is placed on the worktable, fixed by the workpiece fixing device, and the surface to be processed is positioned on one side of the grinding wheel. The grinding wheel rotates to grind the workpiece and complete the processing. A fully automated saw blade grinding production line includes a processing grinding machine and, in conjunction with the processing grinding machine, a finished product placement table, a blank placement table, a cleaning and inspection mechanism, a blade flipping mechanism, and a robotic arm. However, existing fully automated saw blade production lines only have one processing grinding machine. If the number of grinding machines needs to be increased, corresponding auxiliary equipment needs to be added. Therefore, it is necessary to design a fully automated saw blade production line that uses two processing grinding machines for continuous processing without adding auxiliary equipment.

[0003] For example, a Chinese patent discloses a closed truss fully automatic saw blade grinding machine [application number: 202010374385.3], which includes a material placement frame and a movable grinding machine assembly located on the rear side of the material placement frame. The material placement frame is provided with a finished product placement table, a blank placement table, a cleaning and inspection table, and a grinding machine electromagnetic chuck in sequence. The finished product placement table is provided with a finished product lifting device that drives the finished product placement table separately. The blank placement table is provided with a blank lifting device that drives the blank placement table to lift automatically. The cleaning and inspection table includes a fixedly installed water tank, a rotating cleaning component set in the water tank, and a detection component set on the water tank.

[0016] In the aforementioned fully automated grinding production line for large saw blades, the support base is also provided with a hydrostatic support structure for supporting the electromagnet turntable, and a double V-rail structure is provided between the support base and the grinding mechanism and the grinding machine body.

[0017] In the above-mentioned fully automatic grinding production line for large saw blades, the hydrostatic support structure includes a hydrostatic support plate with an annular lubricating fluid storage tank, the No. 1 pulley is set in the annular lubricating fluid storage tank, the bottom surface of the annular lubricating fluid storage tank is provided with a plurality of hydrostatic platforms distributed circumferentially, an oil receiving tray is provided below the support base, and an oil guide hole is provided at the bottom of the hydrostatic support plate.

[0018] The double V-rail structure includes two parallel V-shaped rails with V-shaped grooves and V-shaped sliders corresponding to the V-shaped rails on the rotary table mechanism and the grinding mechanism.

[0019] In the above-mentioned fully automatic grinding production line for large saw blades, a support plate is provided on the lower side of the support base.

[0027] 1. The placement of two trolley loading and unloading devices for placing blank and finished saw blades respectively, two grinding devices, and a flipping and cleaning device with waste blade installation and inspection stations, combined with a six-axis robot, allows the two grinding devices to share a set of equipment for saw blade grinding. This enables the two grinding devices to grind alternately and achieve continuous operation. Compared with a production line using a single grinding device, this reduces the downtime of loading and unloading during operation, effectively improving production efficiency. Furthermore, it reduces the cost of one set of equipment compared to two production lines using a single grinding device.

[0028] 2. The flushing structure and saw blade cleaning mechanism can clean the saw blades separately during saw blade grinding and saw blade flipping, so that the production line in this application does not need to be equipped with a separate cleaning mechanism. This not only reduces equipment costs and equipment placement space, but also reduces the number of steps required for the six-axis robot to operate during production line operation. This provides significant assistance to the application of sharing a set of supporting equipment for two grinding devices.

[0029] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0044] like Figures 1-4 , Figure 9As shown, a fully automated grinding production line for large saw blades includes a six-axis robot 301 and two trolley loading / unloading devices 304 arranged circumferentially around the six-axis robot 301 for placing blanks 302 and finished saw blades 303 respectively, two grinding devices 305, and a blade-turning and cleaning device 306 with a waste blade installation station 128 and an inspection station 129. The grinding device 305 includes a grinding machine body 201, on which a rotary table mechanism 202 and a translation component 203 connected to the rotary table mechanism 202 are arranged. The grinding machine body 201 also has a grinding mechanism 204 and a translation component 203 connected to the grinding mechanism 204. The connected lifting mechanism 205 includes a trolley loading / unloading device 304, a rotary table mechanism 202, a waste sheet installation station 128, an inspection station 129, and a sheet-turning and cleaning device 306, all located within the working radius of the six-axis robot 301. Two grinding devices 305 are located on both sides of the six-axis robot 301 and are arranged opposite each other. Two trolley loading / unloading devices 304 are located on both sides of the six-axis robot 301 and are arranged opposite each other. The sheet-turning and cleaning device 306 is located on the side of the six-axis robot 301 away from the grinding device 305. The waste sheet installation station 128 and the inspection station 129 are located on both sides of the six-axis robot 301 and are arranged opposite each other.

[0045] In this invention, the placement of two trolley loading and unloading devices 304 for placing blanks 302 and finished saw blades 303 respectively, two grinding devices 305, and a flipping and cleaning device 306 with a waste blade installation station 128 and an inspection station 129, in conjunction with a six-axis robot 301, allows the two grinding devices 305 to share a set of equipment for saw blade grinding. This enables the two grinding devices to alternate grinding to achieve continuous operation. Compared with a production line using a single grinding device, this reduces the downtime of loading and unloading the grinding device during operation, effectively improving production efficiency. Furthermore, compared with two production lines using a single grinding device, this reduces the cost of one set of equipment.

[0046] The rotary table mechanism 202 can rotate the saw blade, and the grinding mechanism 204 can grind the saw blade. The translation component 203 can drive the rotary table mechanism 202 to move closer to or away from the grinding mechanism in the horizontal direction. The lifting mechanism 205 can adjust the height of the grinding mechanism. The double V-rail structure 206 can limit the movement of the grinding mechanism 204 and the rotary table mechanism 202.

[0047] Specifically, combining Figures 4-5 , Figures 9-10As shown, the rotary table mechanism 202 includes a support base 210 connected to the translation component 203. The support base 210 is equipped with an electromagnet turntable 211 driven by a first rotation component. The support base 210 also has a waterproof cover 212, which contains a rinsing structure. The translation component 203 can drive the support base 210 to move horizontally closer to or further away from the grinding mechanism. The electromagnet turntable 211 can attract the saw blade. The first rotation component can drive the electromagnet turntable 211 and the saw blade to rotate. The rinsing structure on the waterproof cover 212 can rinse the saw blade during grinding, eliminating the need to place the saw blade in a cleaning mechanism after grinding, thus improving grinding efficiency. The waterproof cover can collect the water generated after cleaning. The flipping and cleaning device 306 includes a material rack body 101, which has a top... The semi-enclosed housing 102 has a sloping opening. The waste blade installation station 128 and the inspection station 129 are set on the material rack body 101 on both sides of the semi-enclosed housing 102. The upper side of the inspection station 129 is provided with a thickness detection head 130. The semi-enclosed housing 102 is provided with a rotary positioning component 103 and a flipping mechanism 105 connected to the flipping plate lifting mechanism 104 on the material rack body 101. The flipping mechanism 105 is located on the upper side of the rotary positioning component 103. The semi-enclosed housing 102 is also provided with a saw blade cleaning mechanism 106. The rotary positioning component 103 can drive the saw blade to rotate. With the help of the saw blade cleaning mechanism 106, the saw blade can be rotated and cleaned. The semi-enclosed housing 102 can collect the water generated during cleaning. The flipping plate lifting mechanism 104 can drive the flipping mechanism 105 to rise and fall, so that the saw blade can be flipped through the flipping mechanism 105. The flushing structure and saw blade cleaning mechanism 106 can clean the saw blade separately during saw blade grinding and saw blade flipping, so that the production line in this application does not need to be set up with a separate cleaning mechanism. This not only reduces equipment costs and equipment placement space, but also reduces the number of steps of the six-axis robot during production line operation, which greatly helps the application to realize that two grinding devices share a set of supporting equipment.

[0048] Waste blade installation station 128 can be used to place waste blades. After the saw blade is placed on the inspection station 129, the thickness of the saw blade can be detected by the thickness inspection head 130.

[0049] Those skilled in the art should understand that the thickness detection head 130 adopts existing technology, and in this embodiment, the GTA32 Keyence detection head is used.

[0050] Specifically, the rinsing structure includes two second connecting pipes symmetrically arranged on the waterproof cover 212, and several second nozzles facing the electromagnet turntable 211 are provided on the second connecting pipes; the saw blade can be rinsed during saw blade grinding through the second connecting pipes and the second nozzles.

[0051] Specifically, combining Figure 6 and Figure 7 As shown, the saw blade cleaning mechanism 106 includes two symmetrically arranged connecting pipes 107 on a semi-enclosed housing 102. Each connecting pipe 107 has several nozzles 108 facing the rotary positioning assembly 103. The connecting pipes 107 are located above the rotary positioning assembly 103, and the nozzles 108 are angled downwards. A drain pipe 109 is provided on the semi-enclosed housing 102, and an inclined platform 110 is provided at the bottom of the housing. The height of the inclined platform 110 gradually increases from the side closer to the drain pipe 109 to the side farther away from it. The saw blade on the rotary positioning assembly 103 can be rinsed through the connecting pipes 107 and the nozzles 108, and the inclined platform 110 can accelerate the drainage of water from the semi-enclosed housing through the drain pipe.

[0052] Specifically, combining Figure 6 and Figure 8 As shown, the rotary positioning assembly 103 includes a saw blade mounting base 111, on which a three-arm support 112 is mounted, and a support rotation assembly capable of driving the three-arm support 112 to rotate. A saw blade positioning rod 113 is located at the center of the three-arm support 112, and several rubber pads 114 are respectively provided on the three arms of the three-arm support 112. The support rotation assembly includes a support driver 115 fixed to the saw blade mounting base 111, and the output shaft end of the support driver 115 is connected to the three-arm support 112. The support driver 115 can drive the three-arm support 112 on the saw blade mounting base 111 to rotate, thereby realizing the rotation and cleaning of the saw blade. The saw blade positioning rod 113 can position the saw blade, and the saw blade positioning rod 113, together with the rubber pads 114, can fix the saw blade on the three-arm support 112.

[0053] Those skilled in the art will understand that the bracket driver 115 may be a rotary cylinder or a motor, etc.

[0054] Specifically, combining Figures 4-7As shown, the saw blade flipping mechanism 105 includes a flipping plate lifting platform 116 connected to the flipping plate lifting mechanism 104. A front axle sleeve 117 and a rear axle sleeve 118 are fixedly connected to both sides of the flipping plate lifting platform 116. A flipping plate rotating shaft 119 is rotatably fitted within the front axle sleeve 117 and the rear axle sleeve 118 via bearings. A flipping structure is fixedly connected to the front end of the flipping plate rotating shaft 119, and the rear end of the flipping plate rotating shaft 119 is connected to a flipping plate driver 120 via a reducer. The flipping plate driver 120 can drive the flipping plate rotating shaft 119 to rotate via the reducer. The rotation of the flipping plate rotating shaft 119 can drive the flipping structure to rotate, thereby achieving the flipping of the saw blade. The front axle sleeve 117 and the rear axle sleeve 118 can support the flipping plate rotating shaft 119. The flipping plate lifting mechanism 104 can drive the flipping plate lifting platform 116 to rise and fall vertically, thereby driving the flipping structure to rise and fall to pick up and place the saw blade.

[0055] Those skilled in the art will understand that the flip plate driver 120 may be a rotary cylinder or a motor, etc.

[0056] Specifically, the flipping structure is positioned directly above the rotary positioning assembly 103. This flipping structure includes an upper flipping plate 121 and a lower flipping plate 122. The upper flipping plate 121 is fixed to the flipping plate pivot 119 by several bolts, and the lower flipping plate 122 is fixed to the upper flipping plate 121 by several bolts. Two electromagnets 123 are fixedly connected to the bottom of the lower flipping plate 122. The lower flipping plate 122 is fixedly connected to the upper flipping plate 121 and the flipping plate pivot 119, and the two electromagnets 123 on the lower flipping plate 122 can attract the saw blade.

[0057] Preferably, a piano cover 124 is connected to the flip plate lifting platform 116, which can prevent debris from splashing out.

[0058] Specifically, the flip plate lifting mechanism 104 includes a flip plate lifting screw 125 and a flip plate lifting driver 126 that drives the flip plate lifting screw 125 to rotate. A flip plate lifting slider 127 is screwed onto the flip plate lifting screw 125, and the flip plate lifting slider 127 is fixedly connected to the flip plate lifting platform 116. The flip plate lifting driver 126 can drive the flip plate lifting screw 125 to rotate, and the rotation of the flip plate lifting screw 125 can drive the flip plate lifting slider 127 to rise and fall in the vertical direction. The vertical rise and fall of the flip plate lifting slider 127 can drive the flip plate lifting platform 116 to rise and fall.

[0059] Those skilled in the art will understand that the flip plate lifting driver 126 can be a rotary cylinder or a motor, etc.

[0060] Preferably, combined with Figure 9 , Figure 11 and Figure 13As shown, the support base 210 is also equipped with a hydrostatic support structure 213 for supporting the electromagnet turntable 211. A double V-guide rail structure 206 is provided between the support base 210, the grinding mechanism 204, and the grinding machine body 201. The hydrostatic support structure 213 can support the first pulley in the first rotating assembly that drives the electromagnet turntable 211 to rotate. The hydrostatic support structure is less expensive than using a plane bearing, and it is easier to repair after damage, resulting in lower maintenance costs. The double V-guide rail structure 206 has low manufacturing costs, and after wear occurs, precision can be adjusted by scraping, making maintenance simple and convenient.

[0061] Specifically, the hydrostatic support structure 213 includes a hydrostatic support plate 226 with an annular lubricant reservoir 225. The first pulley 223 is disposed within the annular lubricant reservoir 225. The bottom surface of the annular lubricant reservoir 225 protrudes and is provided with several circumferentially distributed hydrostatic platforms 227. An oil receiving tray 228 is disposed below the support base 210, and an oil guide hole is provided at the bottom of the hydrostatic support plate 226. The fan-shaped distributed hydrostatic platforms 227, in conjunction with the annular lubricant reservoir 225, can support the first pulley. The lubricant stored in the annular lubricant reservoir 225 reduces friction. Using the hydrostatic support plate 226 and hydrostatic platforms 227 to support the first pulley instead of a planar bearing reduces costs, and repairs can be made by scraping after damage, resulting in low maintenance costs.

[0062] Specifically, the double V-rail structure 206 includes two parallel V-rails 207 with V-grooves, and V-slider 208s corresponding to the V-rails 207 on the rotary table mechanism 202 and the grinding mechanism 204. The two V-rails 207 corresponding to the rotary table mechanism 202 are horizontally arranged, while the V-rail 207 corresponding to the grinding mechanism 204 is vertically arranged. A lubricating oil groove 209 is provided within the V-groove. The V-rail 207, with its V-groove and V-slider 208, has a simple structure, low manufacturing cost, and allows for precision adjustment by scraping after wear, making maintenance simple and convenient. Lubricating oil can be added to the lubricating oil groove 209 to reduce wear.

[0063] Preferably, combined with Figure 9 , Figures 11-13As shown, a support plate 214 is provided on the lower side of the support base 210. One end of the support base 210 is rotatably connected to the support plate 214 via an adjusting shaft 215, and the other end of the support base 210 is connected to the support plate 214 via a support member 216. An arc-shaped limiting structure is also provided on the side of the support plate 214 near the support member 216. This arc-shaped limiting structure includes adjusting plates 217 fixed on both sides of the support plate 214. An arc-shaped limiting groove 218 is provided on the adjusting plate 217, and a limiting bolt 219 is fixedly connected to the support base 210 and inserted into the arc-shaped limiting groove 218. The support base 210 can be rotated by the rotatable connection between the adjusting shaft 215 and the support plate 214. Adjusting the height of the support member 216 can adjust the angle of the support base, thereby leveling the support base. The arc-shaped limiting groove 218 on the adjusting plate 217, in conjunction with the limiting bolt 219, can limit the rotation of the support base.

[0064] Specifically, the support member 216 includes a threaded sleeve 220 fixed to the bottom of the support base 210 and an adjusting bolt 221 screwed to the threaded sleeve 220. The bottom end of the adjusting bolt 221 abuts against the support plate 214. Three support members 216 are provided, arranged in a triangular pattern, with the two side support members 216 symmetrically arranged along the center line of the middle support member 216. Rotating the adjusting bolt allows adjustment of its length between the support base 210 and the support plate. Adjusting the length of the adjusting bolt between the support base 210 and the support plate allows adjustment of the angle of the support base. The three support members 216 improve the stability of the support base.
