Description

Technical Field

[0001] This utility model belongs to the field of diamond saw blade welding technology, specifically relating to a fully automatic saw blade laser welding machine. Background Technology

[0002] Diamond saw blades mainly consist of two parts: the saw blade body and the cutting head. The saw blade body is the main supporting part that holds the cutting head together, while the cutting head is the part that performs the cutting during use.

[0003] Laser welding technology for diamond saw blades uses a high-temperature laser beam to melt the contact edge between the saw head and the substrate, forming a metallurgical bond. This welding process, where multiple saw heads are welded to each saw blade, is currently the primary method for automated production. This involves placing a single saw blade substrate on a positioning turntable, using a gripping device to grab and move the saw head to the side of the substrate, clamping and fixing both the substrate and the saw head, and then welding them using laser welding equipment. After welding a single saw head, the clamps are released, the turntable rotates, and the gripping device grabs and moves the next saw head for welding. However, the laser welding equipment does not operate during the rotation of the saw blade substrate and the grabbing of the next saw head. Therefore, this method of diamond saw blade welding is inefficient. Using multiple laser welding devices simultaneously would lead to interference between adjacent welding equipment and higher costs. Summary of the Invention

[0004] This invention addresses the problem of low welding efficiency in existing diamond saw blade production processes. In this method, the laser welding equipment is not operational while the saw blade substrate rotates to pick up a new blade after the previous one is welded. Furthermore, using multiple laser welding devices simultaneously can lead to interference between adjacent devices and high costs. This invention provides a fully automatic saw blade laser welding machine. By incorporating a rotary table and multiple welding stations, the laser welding equipment is moved to weld another saw blade substrate and blade during the rotation of the saw blade substrate and the picking up of a new blade. This effectively utilizes the idle time of the laser welding equipment and improves the welding efficiency of diamond saw blades.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A fully automatic laser welding machine for welding saw blade heads to saw blade substrates includes a frame and a rotating mechanism, a feeding mechanism, a conveying mechanism, and a welding mechanism mounted on the frame. The rotating mechanism includes a rotary table and a first power component for driving the rotary table. Multiple workstations are arranged on the rotary table, each workstation equipped with a saw blade positioning component. The saw blade positioning component includes a limiting component and a second power component. The limiting component is used to fix the saw blade substrate, and the second power component is used to drive the limiting component to rotate. The multiple workstations include loading / unloading workstations and welding workstations. The feeding mechanism provides saw blade heads to the welding workstations, and the conveying mechanism is used to pick up and place saw blade substrates from the loading / unloading workstations. The welding mechanism includes a laser welding device, which corresponds vertically to the welding workstations. The position of the laser welding device relative to the frame is adjustable, and it is used to weld the saw blade substrates and saw blade heads to the welding workstations. The rotating mechanism adjusts the saw blade substrates at the loading / unloading workstations and welding workstations, and the laser welding device is moved to weld the saw blade substrates and saw blade heads to different welding workstations.

[0007] Preferably, the frame is further provided with multiple saw blade bases for placing saw blade substrates, and the multiple saw blade bases are respectively used to store saw blade substrates before and after the welding head.

[0008] Preferably, the conveying mechanism includes a first sliding component, on which a slider is slidably disposed. A plurality of adsorption components are fixedly disposed on the slider. The adsorption components are used to adsorb the saw blade substrate. The saw blade base and the loading / unloading station are both located below the first sliding component. The plurality of adsorption components adsorb the saw blade substrate without welded blade heads and the saw blade substrate with welded blade heads on the loading / unloading station, respectively. Then they move simultaneously, placing the saw blade substrate with welded blade heads on the corresponding saw blade base and placing the saw blade substrate without welded blade heads on the corresponding saw blade base at the loading / unloading station.

[0009] Preferably, both sides of the frame are provided with a cutter head feeding mechanism for feeding cutter heads to the feeding mechanism.

[0010] Preferably, multiple loading / unloading stations and welding stations are provided, allowing for simultaneous loading / unloading of multiple saw blade substrates and welding of the saw heads.

[0011] Preferably, the welding mechanism further includes a second sliding component, a third sliding component, and a fourth sliding component. The second sliding component is provided on the frame, the third sliding component is slidably disposed on the second sliding component, and the fourth sliding component is provided on the third sliding component. The laser welding device is slidably disposed on the fourth sliding component. The second sliding component is used to drive the laser welding device to move back and forth, and the third sliding component is used to drive the laser welding device to move left and right. The laser welding device can be adjusted by the second sliding component to adapt to saw blade substrates of different sizes, and the laser welding device can be adjusted by the third sliding component to move between different welding stations.

[0012] Preferably, the frame is provided with a first clamping member and a second clamping member. The first clamping member is used to clamp and fix the saw blade base at the corresponding welding station, and the second clamping member is used to clamp and fix the cutting head at the corresponding welding station to prevent the saw blade base or cutting head from shifting position during the welding process.

[0013] Preferably, both the first clamping member and the second clamping member include pneumatic grippers, and the clamping gaps of the pneumatic grippers of the first clamping member and the second clamping member are corresponding, so that the laser welding equipment welds the saw blade base and the contact edge of the cutting head between the first clamping member and the second clamping member.

[0014] The beneficial effects of this utility model through the above technical solution are as follows:

[0015] 1. This utility model sets up multiple loading and unloading stations and welding stations. Each welding station is equipped with a feeding mechanism and a cutting head feeding structure. At the same time, multiple saw blade base outer cutting head welding work and multiple saw blade base loading and unloading work are carried out, which effectively improves the production efficiency of circular saw blades.

[0016] 2. This utility model, by setting up two saw blade bases for placing unwelded saw blade substrates, two loading and unloading stations, and two saw blade bases for placing saw blade substrates with completed blade head welding, in conjunction with a first sliding component and four adsorption components, simultaneously completes the unloading of welded saw blades and the loading of unwelded saw blade substrates at the loading and unloading stations, effectively improving saw blade processing efficiency.

[0017] 3. This utility model sets up two welding stations and uses a movable laser welding device. While welding the saw blade base and the cutting head at one welding station, the saw blade base at the other welding station rotates at a corresponding angle and a new cutting head is supplied. This fully utilizes the time required to replenish the cutting head and rotate the saw blade base at a certain angle after each cutting head is welded. By using this replacement interval, the saw blade base and the cutting head at the other welding station can be welded. Without adding laser welding equipment, the efficiency of saw blade cutting head welding is greatly improved, thus increasing production efficiency. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0035] The directions described in this utility model, such as front / back, left / right, and up / down, are shown in the accompanying drawings. Figure 1 The indicated location, specifically, is as follows: Figure 1 As shown, the rotating mechanism 3 is located in front of the feeding mechanism 4, the welding mechanism 6 is located above the rotating mechanism 3, and the saw blade base 7 is located on the left and right sides of the rotating mechanism 3 respectively.

[0036] like Figures 1-12 As shown, this embodiment provides a fully automatic saw blade laser welding machine for welding the cutting head onto the saw blade substrate 1, including a frame 2 and a rotating mechanism 3, a feeding mechanism 4, a conveying mechanism 5 and a welding mechanism 6 disposed on the frame 2;

[0037] The rotating mechanism 3 includes a rotating platform 31 and a first power component 32 for driving the rotating platform to rotate. The rotating platform 31 has multiple workstations, four of which are evenly distributed around the circumference of the rotating platform 31. Each workstation is equipped with a saw blade positioning component, which includes a limiting component 33 and a second power component 34. The limiting component 33 is used to position and fix the saw blade base 1, and the second power component 34 is used to drive the limiting component 33 to rotate. Specifically, the first power component 32 and the second power component 34 are servo motors. The first power component 31 is fixedly connected to the frame 2, and its output end is fixedly connected to the lower center of the rotating platform 31. The second power component 34 is fixedly disposed on the lower side of the rotating platform 31, and its output end is fixedly connected to the limiting component. The limiting component 33 has a mandrel on its upper part and a tensioning cylinder on its lower part. It also has an adjusting ring that slides up and down. The upper end of the mandrel extends out of the adjusting ring and the extended part matches the thickness of the saw blade base 1. By raising or lowering the height of the adjusting ring, it can accommodate saw blade bases 1 of different thicknesses. The mandrel is composed of multiple arc-shaped blocks arranged in a circumferential array. By fitting the saw blade base onto the mandrel, and then driving the mandrel to open radially with the tensioning cylinder, the saw blade base can be fixed. The lower part of the tensioning cylinder is fixedly connected to the output end of the second power component 34. Therefore, when welding the cutter head on the outside of the saw blade base 1, after each cutter head welding is completed, the limiting component 33 is driven by the second power component 34 to rotate by a corresponding angle, and a new cutter head is provided there, so that the welding processing of the next cutter head can be carried out.

[0038] As one possible implementation, the limiting component 33 adopts the saw blade positioning component in the base saw blade positioning turntable of the saw blade laser welding machine disclosed in the utility model patent with patent publication number CN206140003U.

[0039] Both sides of the frame 2 are provided with a blade feeding mechanism 9, which is used to feed the blades to the feeding mechanism 4. Specifically, the blade feeding mechanism is used to realize the automated feeding of the blades and form an effective directional positioning, providing a basis for the gripping and clamping welding process of the feeding mechanism 4. The blade feeding mechanism adopts the blade feeding device of the saw blade laser welding machine disclosed in the utility model patent with patent publication number CN206140002U, or other existing technologies that meet the requirements of saw blade blade feeding and positioning.

[0040] The multiple workstations include loading / unloading workstations and welding workstations. Both loading / unloading workstations and welding workstations are set in multiples. Specifically, there are two loading / unloading workstations, which can simultaneously load and unload two saw blade bases 1. There are two welding workstations, which can simultaneously weld the blade heads of two saw blade bases 1. The first power component 32 drives the rotary table 31 to rotate 180°, thereby realizing the position exchange of the limiting components 33 of the two loading / unloading workstations and the two welding workstations.

[0041] The feeding mechanism 4 is used to provide cutting heads to the welding station. There are two feeding mechanisms 4, which are used to provide cutting heads to two welding stations respectively. The feeding mechanism 4 includes a rotary cylinder, a sliding member, and a gripping member. The rotary cylinder is fixedly installed on the frame. The sliding member is fixedly installed at the output end of the rotary cylinder. The sliding member is a sensorless cylinder. The gripping member is fixedly installed on the piston of the sliding member. The gripping member is a pneumatic claw used to grip the cutting head. Specifically, the rotary cylinder drives the pneumatic claw to rotate above the cutting head fed by the cutting head feeding mechanism 9. The sliding member drives the pneumatic claw to approach the cutting head. Then the gripping member grips and fixes the cutting head. The rotary cylinder drives the pneumatic claw to rotate again until the cutting head is facing the saw blade base 1 of the corresponding welding station. The sliding member drives the gripping member to move closer to the saw blade base 1. After the cutting head reaches the corresponding position, it is clamped and fixed by the second clamping member 82 for welding.

[0042] As one possible implementation, the feeding structure 4 adopts the blade gripping device in the blade feeding, gripping and clamping system of the saw blade laser welding machine disclosed in the invention patent with patent publication number CN106271137B.

[0043] The frame 2 is also provided with multiple saw blade bases 7 for placing saw blade bases 1. The saw blade bases 7 are configured in two groups, respectively set on both sides of the loading and unloading station, and are used to place the saw blade bases 1 before and after the welding head. Each group of saw blade bases 7 is configured with two, and the distance between the two saw blade bases 7 is equal to the distance between the two loading and unloading stations. A saw blade guide rod is detachably installed on the saw blade base 7. The saw blade base is sleeved on the saw blade guide rod, which limits the saw blade base 1 when it is placed in a screw position. On the one hand, it prevents the screw-placed saw blade base from tipping over, and on the other hand, it guides its lifting and moving to ensure that it is aligned vertically.

[0044] The conveying mechanism 5 is used to pick up and place the saw blade base 1 on the loading and unloading station. The conveying mechanism 5 includes a first sliding component 51, on which a slider 52 is slidably disposed. The first sliding component 51 is a rodless cylinder that drives the slider 52 to slide left and right. Multiple adsorption components 53 are fixedly disposed on the slider 52. The adsorption components 53 are used to adsorb the saw blade base 1. The saw blade base 7 and the loading and unloading station are both located below the first sliding component 51. Specifically, four adsorption components 53 are set, corresponding vertically to two adjacent saw blade bases 7 and two loading and unloading stations, respectively, and can extend downwards simultaneously to adsorb and fix two saw blade bases. The saw blade base 1 with unwelded cutter heads placed on the seat 7 and the saw blade base 1 with cutter heads already welded on the loading and unloading station are moved by the first sliding component 51 driving the slider 52 to move with the four adsorption components 53. The adsorption components 53 that originally corresponded to the two saw blade bases 7 with unwelded cutter heads are moved to correspond to the loading and unloading station. The adsorption components 53 that originally corresponded to the loading and unloading station are moved to correspond to the other two saw blade bases 7 with welded cutter heads. Then the adsorption components 53 drive the corresponding saw blade base 1 to move downward and place it, thus completing the loading and unloading of the saw blade base 1 on the loading and unloading station.

[0045] The adsorption assembly 53 includes a lifting cylinder, an adsorption cylinder, a fixed plate, an adsorption plate, and adsorption magnets. Multiple lifting cylinders are fixedly mounted on the slider 52. An adsorption cylinder and a fixed plate are fixedly mounted at the output end of the lifting cylinder, and an adsorption plate is fixedly mounted at the output end of the adsorption cylinder. Multiple adsorption magnets, which are permanent magnets or electromagnets, are fixedly mounted on the adsorption plate. The fixed plate has through holes for the adsorption magnets to pass through. The adsorption cylinder drives the adsorption plate to move downward, causing the adsorption magnets to extend out of the fixed plate and adsorb the saw blade substrate 1. The adsorption cylinder drives the adsorption plate to move upward, causing the adsorption magnets to move upward to the top of the fixed plate, while the saw blade substrate 1 is blocked, thus detaching from the adsorption magnets. This completes the detachment of the saw blade substrate 1 after the adsorption assembly 53 has placed it.

[0046] The welding mechanism 6 includes a laser welding device 64, which corresponds vertically to the welding station. The position of the laser welding device 64 relative to the frame 1 is adjustable. By adjusting the position of the laser welding device 64, on the one hand, when processing saw blade substrates 1 of different diameters, it can be ensured that the welding position of the laser welding device 64 corresponds to the welding position of the corresponding saw blade substrate 1 and the cutting head. On the other hand, by adjusting the position of the laser welding device 64, welding processing can be performed on saw blade substrates 1 at different welding stations. Specifically, the two welding stations correspond horizontally, and the laser welding device 64 can be adjusted to move left and right to weld the saw blade substrates 1 and the corresponding cutting heads at the two welding stations respectively. The laser welding device 64 is used to weld the saw blade substrates 1 and the cutting heads at the welding station. The laser welding device 64 adopts a laser welding head of model HK30.

[0047] The welding mechanism 6 further includes a second sliding component 61, a third sliding component 62, and a fourth sliding component 63. The second sliding component 61 is provided on the frame 2, the third sliding component 62 is slidably disposed on the second sliding component 61, and the fourth sliding component 63 is disposed on the third sliding component 62. A laser welding device 64 is slidably disposed on the fourth sliding component 63. The second sliding component 61 is used to drive the laser welding device 64 to move back and forth, and the third sliding component 62 is used to drive the laser welding device 64 to move left and right. The position of the laser welding device 64 is adjusted by the second sliding component 61 and the third sliding component 62 so that it corresponds vertically with the contact position (i.e., the position to be welded) between the saw blade base 1 and the blade head. Then, the fourth sliding component 63 drives the laser welding device 64 to move up and down closer to the position to be welded for welding processing.

[0048] As one possible implementation, the second sliding component 61, the third sliding component 62, and the fourth sliding component 63 are all rodless cylinders.

[0049] The frame 2 is provided with a first clamping member 81 and a second clamping member 82. The first clamping member 81 is used to clamp and fix the saw blade base 1 on the corresponding welding station, and the second clamping member 82 is used to clamp and fix the cutter head on the corresponding welding station.

[0050] Both the first clamping member 81 and the second clamping member 82 include pneumatic grippers. The clamping gaps of the pneumatic grippers of the first clamping member 81 and the second clamping member 82 are corresponding. While ensuring that the saw blade base 1 and the cutting head are clamped and fixed, there is a gap between the grippers of the two corresponding pneumatic grippers, thereby avoiding the welding position between the saw blade base 1 and the corresponding cutting head, and ensuring that the laser welding equipment 64 can weld the contact edge between the saw blade base 1 and the corresponding cutting head from top to bottom.

[0051] The first power assembly 32 drives the rotary table 31 to rotate to the edge of the saw blade base at the loading and unloading station, which passes through the clamping gap of the two first clamping members 81 and stops. Then, the first clamping members 81 drive the jaws to clamp and fix the corresponding saw blade base 1. The two feeding mechanisms 4 grab the cutter head fed by the cutter head feeding mechanism 9 and place it in the clamping gap of the second clamping member 82, and the cutter head contacts the saw blade base 1. Then, the second clamping member 82 clamps and fixes the cutter head, which facilitates subsequent welding, avoids positional displacement during welding, and ensures accurate welding position.

[0052] As one possible implementation, the clamping system formed by the first clamping member 81 and the second clamping member 82 can adopt the welding clamping assembly structure of the saw blade laser welding machine disclosed in the utility model patent with patent publication number CN206139911U.

[0053] In use, firstly, the saw blade base 1 (saw blade base 1 without welded blade head) on the two saw blade bases 7 on one side of the rotating mechanism 3 is transported by the conveying mechanism 5 to the two loading and unloading station limiting components 33, and is tightened and fixed by the limiting components 33. Then, the first power component 32 drives the rotary table 31 to rotate 180°, so that the limiting components 33 of the two loading and unloading stations rotate to the two welding stations, and the saw blade base 1 on them is located in the clamping gap of the two first clamping members 81 respectively. At the same time, the feeding mechanism 4 grabs and moves the blade head conveyed by the blade head feeding mechanism 9 to the clamping gap of the two second clamping members 82, and is clamped and fixed by the corresponding second clamping members 82. At this time, the clamped blade head is in contact with the corresponding saw blade base 1, completing the preparation before welding.

[0054] Subsequently, the position of the laser welding device 64 is adjusted by the second sliding component 61 and the third sliding component 62 so that it corresponds vertically with the contact position (i.e. the position to be welded) between the saw blade base 1 and the cutting head of one of the welding stations. Then, the fourth sliding component 63 drives the laser welding device 64 to move downward and closer to the position to be welded for welding processing.

[0055] After the welding of the blade head is completed, the fourth sliding component 63 drives the laser welding equipment 64 to rise and move above another welding station to weld the saw blade base 1 and the blade head at the other welding station. During this process, the first clamping member 81 and the second clamping member 82 corresponding to the welding station that has completed welding loosen their clamping on the saw blade base 1 and the blade head. The second power component 32 of the welding station drives the limiting component 33 and the saw blade base 1 on it to rotate by a corresponding angle. At the same time, the corresponding feeding mechanism 4 grabs the next blade head and moves it into the clamping gap of the corresponding second clamping member 82. The holding member 81 and the second clamping member 82 clamp and fix the saw blade base 1 and the new cutter head again. When the replacement is completed, the saw blade base 1 and the corresponding cutter head of the other welding station are welded. Then, the new cutter head is moved to the welding position above the new cutter head and the new cutter head is welded to the saw blade base 1. By repeating the above process, the time when the new cutter head is fed and the saw blade base 1 rotates after the saw blade base 1 is welded to one cutter head can be used to weld the other welding station. That is, the two saw blade bases 1 are welded to each other at the same time by a laser welding device 64, which effectively improves the processing efficiency.

[0056] After the cutting heads on the saw blade bases 1 at the two welding stations are welded, the first power unit 32 drives the rotary table 31 to rotate 180° again, and the positions of the loading / unloading station and the welding station are swapped again. The saw blade bases 1 with the completed cutting head welding are rotated to the loading / unloading station, and the saw blade bases 1 without welding are rotated to the welding station. Then, while the laser welding equipment 64 is used to weld the cutting heads on the two new saw blade bases 1, the conveying mechanism 5 is started again to move the four adsorption components 53 to correspond vertically with the two adjacent saw blade bases 7 (at this time, the two adjacent saw blade bases 7 are the saw blade bases 7 for placing the saw blade bases 1 without welding cutting heads) and the two loading / unloading stations. The four adsorption components 53 move downwards simultaneously to adsorb and fix the corresponding saw blade substrate 1. Then, the four adsorption components 53 move upwards, and the slider 52 driven by the first sliding component 51 moves the four adsorption components 53 to move two of the adsorbed and fixed saw blade substrates 1 (saw blade substrates 1 without welded blade heads) to correspond to the two loading and unloading stations respectively. The other two saw blade substrates 1 (saw blade substrates 1 after multiple blade heads have been welded in the circumferential position) are moved to correspond to the other two saw blade bases 7 (i.e., the two saw blade bases 7 on the other side of the rotating mechanism 3 used to place the welded blade heads). The four adsorption components 53 move downwards to complete the loading of new saw blade substrates 1 and the unloading and placement of welded saw blade substrates 1.

[0057] By repeating the above process, the continuous welding of the saw blade base 1 and the cutting head can be completed.

[0058] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
