Description

Technical Field

[0001] The invention relates to the field of motor rotor production equipment, and in particular to welding and gluing equipment for a motor rotor production device for an EC fan. Background Art

[0002] At present, the existing automatic production equipment for magnetic tile rotors for EC fans has basically realized the full automation of the assembly process, but the connection between the various workstations of the existing automatic production equipment for magnetic tile rotors is still not perfect, which affects the efficiency of group production, and lacks automatic detection equipment in each link, and it is impossible to detect the defective products produced in the production process, which affects the product yield. Therefore, it is necessary to optimize it to improve the automatic production efficiency of magnetic tile rotors. For example, CN116618832A discloses an integrated production line for automatic welding, detection, cleaning, and rust prevention of rotors and stators, including a stepping conveyor line, laser welding equipment, laser cleaning equipment, appearance defect detection equipment, flatness detection equipment, three-coordinate detection and positioning equipment, coding equipment, air shower cleaning equipment, and oil spray rust prevention equipment. After the workpiece is welded at the welding equipment, it enters the stepping conveyor line, and passes through the stepping conveyor line to enter the laser cleaning equipment, appearance defect detection equipment, flatness detection equipment, three-coordinate detection and positioning equipment, coding equipment, air shower cleaning equipment, and oil spray rust prevention equipment to complete the process. In this production line, efficient welding work can be completed, and the whole process is automated. Only by placing the workpiece on the welding fixture, the welding work of the workpiece and a full range of inspection, cleaning, and rust prevention work can be completed. Moreover, this production line adopts precise laser technology and multiple CCDs for three-dimensional inspection to ensure the quality of the produced workpieces. Although the invention has a self-inspection function during production, it only realizes the automatic welding of the rotor, and cannot assemble the rotor from the shaft from the very beginning. The casing and the shaft need to be manually assembled together and then automatically welded. The process is cumbersome and the full automation of rotor production is not fully realized. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that the existing rotor production equipment cannot realize the assembly and production of the rotor from the shaft, and the complete automatic assembly and production of the rotor cannot be realized. In order to solve the above problem, the present invention provides the following technical solutions: A welding and gluing device for an EC fan motor rotor production device, comprising a workbench, a shaft material tray is provided on the workbench, a shaft pressing device is provided adjacent to the shaft material tray, the shaft pressing device is connected to the laser welding equipment through a third conveying device, a runout detection mechanism is provided adjacent to the laser welding equipment, and the runout detection mechanism and the gluing mechanism perform engineering interaction through the third conveying device.

[0004] The present invention provides a shaft material tray, automatically takes out the rotor shaft, and then transports the shaft to a shaft pressing device to complete the assembly of the shaft and the casing, and then transports the assembled casing to a laser welding device to complete the welding of the shaft and the casing. After welding, the casing is transported to a detection device to detect whether the outer circle runout of the casing is qualified. After the detection, the casing is transported to a gluing mechanism to complete gluing, thereby realizing the production of the rotor starting from the rotor shaft, automatically completing welding, runout detection and gluing, further improving the degree of automation of rotor production, and each workstation is independently arranged, and the movement of the rotor casing on each workstation is achieved through a conveying device, so that the equipment at each workstation can work independently, and when a single device fails, it can be taken out and replaced separately, without the need to disassemble the entire production line, thereby improving the work efficiency of maintenance personnel.

[0005] Preferably, the shaft material tray includes an ejection mechanism and a telescopic mechanism, a 7-shaped ejection block is arranged below the ejection mechanism, the tail of the ejection block is located directly above the shaft material groove, the shaft material groove is arranged between the telescopic mechanism, and the telescopic mechanism is two symmetrically arranged metal blocks with grooves.

[0006] The shaft material tray of the present invention is used to store rotor shafts. When they need to be taken out, the telescopic mechanism will take the shafts out of the shaft material tray one by one, and then the ejection mechanism will eject the shafts from the shaft material tray from left to right to the first clamping hand, and the shafts will be clamped by the first clamping hand. The L-shaped ejection block arranged below the ejection mechanism is to match the shape of the shaft material groove. The shaft material groove is a gap formed between two symmetrically arranged metal blocks with grooves of the telescopic mechanism. The width of the shaft material groove is slightly larger than the width of the shaft, which is convenient for placing the shaft in the shaft material groove and allowing the shaft to remain horizontally placed in the shaft material groove. The shaft will not fall from the material groove or get stuck and cannot be ejected. The grooves on the two symmetrically arranged metal blocks of the telescopic mechanism are to increase friction, making it more convenient to take out the shaft.

The first flipping mechanism can be flipped 360 degrees by the action of a rotating motor, thereby driving the first gripper to flip 360 degrees. After the first gripper grips the shaft, for the convenience of subsequent processes, it is necessary to adjust the shaft from a horizontal state to a vertical state. Therefore, the rotating motor rotates to drive the first flipping mechanism to flip, thereby driving the shaft clamped by the first gripper to rotate and adjust it to a vertical state.

[0009] Preferably, a shaft placement position is provided between the shaft material tray and the shaft pressing device, and the shaft placement position is provided with a shaft groove for placing the shaft gripped by the first gripper and waiting for the second gripper to grip it. The second gripper is arranged on the first conveying device, and the second gripper is provided with a detection device. After the second gripper grips the shaft, the second gripper rotates, and the detection device detects the shaft to ensure that the threaded end of the shaft always faces upward. After the detection is passed, the second gripper grips the shaft and places the shaft on the base of the shaft pressing device.

[0010] After the first gripper of the present invention grips the shaft, it places it in the shaft groove in the shaft placement position. The shaft placed in the shaft groove is gripped by the second gripper, and the second gripper is arranged at the second slide groove from left to right of the first conveying device.

The second gripper grips the shaft sent by the first gripper, and the detection device arranged on the second gripper detects it, and then rotates it after the detection. Because the shaft is divided into upper and lower ends, one section is provided with a thread called the threaded end, and the other end is not provided with a thread. In order to facilitate subsequent pressing, the threaded end of the shaft needs to be facing upwards before being sent into the pressing device, and then the shaft is placed on the base of the pressing device after the threaded end is facing upwards.

[0012] The base of the pressing device of the present invention is used to place the shaft to be pressed into the casing, the casing placement station is used to place the casing, and the pressing head is used to press the shaft into the casing. The spring arranged below the base of the pressing device serves as a supporting device and has an automatic pop-up function. After the shaft is pressed, the spring will automatically pop up, making it convenient for the fourth gripper to clamp the casing after the shaft is pressed. The casing placement station also uses a spring as a supporting device in order to cooperate with the spring below the base of the pressing device. After the shaft is pressed, the two will automatically pop up, making it convenient for the fourth gripper to clamp the casing, and the efficiency of pressing the next pressing casing can also be improved.

[0013] Preferably, the pressing device is further provided with a third gripper, and the third gripper is arranged between the pressing head and the casing placement station. The pressing device is also connected to the casing material tray, and 8 casing material sub-traces are evenly distributed on the casing material tray. A second conveying device is arranged next to the casing material tray, and the second conveying device is connected to the casing material tray through a casing material port. The casing on the casing material sub-traces passes through the casing material port and then the second conveying device is used to transport the casing to the rear side of the pressing device. The casing is clamped by the third gripper and placed on the casing placement station, and then the pressing head moves downward to press the shaft into the casing, and then the fourth gripper places the casing clamping position after the shaft is pressed to the first placement position of the pressing casing.

[0014] The casings that need to be pressed in the present invention all come from the casing material tray arranged at the rear of the pressing device. When the pressing device needs a casing, the casing material tray will rotate, and the casing material sub-tray with the largest number of casings currently stored will be rotated to the casing material opening, and the gripper installed on the second transfer device will grip the top casing of the casing material sub-tray at the casing material opening. After gripping the casing, the casing will be transported to the back of the pressing device, and then the third gripper arranged on the pressing device will rotate to grip the casing behind the pressing device, and then Rotate back and place the clamped casing at the casing placement station, then press the pressure head downward to press the shaft into the casing, and finally get the pressed casing. After getting the pressed casing, the fourth gripper grips the pressed casing after the shaft is pressed, and sends the pressed casing to the first placement position of the pressed casing through the first conveying device. The fourth gripper is set in the third slide groove from left to right of the first conveying device. The width of the slide groove matches the connection between the fourth gripper and the first conveying device. The fourth gripper can slide through the slide groove on the first conveying device, and the fourth gripper can also rotate.

[0016] After the shaft-entering casing of the present invention is pressed, it is clamped by the fourth gripper and then transported to the first placement of the shaft-pressing casing. When placed, the first placement of the shaft-pressing casing is moved to the end close to the shaft-pressing device through the conveying device of the shaft-pressing casing placement, and then the fourth gripper puts the shaft-entering casing on the first placement of the shaft-pressing casing. The conveying device of the shaft-pressing casing placement is provided with a slide groove, and the first placement of the shaft-pressing casing is installed on the slide groove. The slide groove realizes the sliding of the first placement of the shaft-pressing casing on the conveying devices of several placements of the shaft-pressing. Since the laser welding equipment is not connected to the shaft-pressing device, the first placement of the shaft-pressing casing also plays a role in laser welding. The direct engineering interaction between the optical welding equipment and the pressing device not only enhances the linkage between the two, but also ensures their independence. A failure in one device will not affect the other device. Even if a failure occurs, only the device needs to be repaired or replaced directly. At the same time, since each device is independent of each other and only interacts with each other through each transmission device, the equipment layout on the workbench can be more compact, more equipment can be set up in a limited space, and more products can be produced under the same budget, reducing the production cost of the product and improving the production efficiency of the product.

[0017] Preferably, the laser welding equipment welds the shaft to the housing to prevent the shaft from falling off.

[0018] When the input shaft casing is placed at the first placement position of the shaft pressing casing, the fifth gripper arranged on the third conveying device clamps the input shaft casing from the first placement position of the shaft pressing casing, the fifth gripper is arranged at the leftmost slide slot of the third conveying mechanism, and then the fifth gripper rotates to transport the input shaft casing to the vicinity of the sixth gripper, the sixth gripper is arranged at the second slide slot from left to right of the third conveying mechanism, the sixth gripper clamps the input shaft casing sent from the fifth gripper, and then transports the input shaft casing to the second placement position of the shaft pressing casing, the second placement position of the shaft pressing casing can move forward and backward, and transports the input shaft casing placed on the second placement position of the shaft pressing casing forward to the laser welding equipment, the laser welding equipment is provided with a welding position, when the second placement position of the shaft pressing casing sends the input shaft casing to the welding position, the laser welding equipment will automatically perform welding to weld the shaft and the casing to prevent the shaft from falling off, and after welding is completed, the second placement position of the shaft pressing casing moves backward to take the input shaft casing out from the welding position.

[0019] Preferably, the vibration detection mechanism includes a detection head, a rotating mechanism is provided on each side of the detection head, a circle of grooves is provided on the rotating mechanism, a belt is wrapped around the groove, and a vibration detection table is also provided under the vibration detection mechanism. The vibration detection table is used to place the detected casing, and the detected casing is clamped by an eighth gripper and transported to the gluing mechanism through a third conveying device connected to the eighth gripper.

[0020] After the welding of the shaft-entering casing of the present invention is completed, the seventh gripper arranged on the third conveying mechanism will grip the welded shaft-entering casing placed at the second placement position of the shaft pressing casing. The seventh gripper is arranged at the third slide slot from left to right of the third conveying mechanism. After the gripping is completed, the seventh gripper transports the shaft-entering casing to the runout detection mechanism. The runout detection mechanism is used to detect whether the outer circle runout of the casing is qualified. The runout detection mechanism can move forward and backward. When detecting, the runout detection mechanism will move forward to make the detected shaft-entering casing close to the runout detection mechanism. The belt provided by the runout detection mechanism is The rotating mechanism drives the belt to move, fitting the belt with the outer shell of the shaft casing. The belt will drive the shaft casing to rotate, so as to detect whether the outer circle runout of the casing is qualified. If it is detected that it is unqualified, the seventh clamp will remove the shaft casing from the production line. The surface of the detection head is provided with threads. During detection, the detection head will be attached to the upper surface of the shaft casing. When the shaft casing rotates, it will drive the detection head to rotate.

[0022] After the shaft-entering casing of the present invention passes the runout detection, the seventh gripper will place the shaft-entering casing that has passed the detection on the runout detection table, and then the eighth gripper arranged on the third conveying device will clamp the shaft-entering casing on the runout detection table and transport it to the gluing mechanism. The eighth gripper is arranged at the rightmost slide slot of the third conveying device. After the eighth gripper clamps the shaft-entering casing, it is turned 180 degrees to turn the shaft-entering casing over, and the turned shaft-entering casing is transported to the gluing mechanism for gluing. The eighth gripper places the shaft-entering casing on the gluing machine At the gluing position of the structure, the gluing telescopic device performs telescopic movement during gluing, moves the glue head to the inside of the shaft entry casing, aligns the glue head with the inner wall of the shaft entry casing, and after alignment, the rotating mechanism arranged just below the gluing position starts to rotate, and the rotating mechanism drives the shaft entry casing to rotate as well.

[0037] Embodiment 1:

[0038] See also Figure 1 and Figure 2 An embodiment of the present invention provides a welding and gluing device for a motor rotor production device for an EC fan, comprising a workbench 1, on which is provided a shaft material tray 5, adjacent to which is provided a shaft pressing device 19, the shaft pressing device 19 being connected to a laser welding device 20 via a third conveying device 26, adjacent to which is provided a jitter detection mechanism 21, the jitter detection mechanism 21 and the gluing mechanism 22 performing engineering interaction via the third conveying device 26.

[0039] The present invention provides a shaft material tray 5, automatically takes out the rotor shaft, and then transports the shaft to the shaft pressing device 19 to complete the assembly of the shaft and the casing, and then transports the assembled casing to the laser welding equipment 20 to complete the welding of the shaft and the casing. After welding, the casing is transported to the detection device to detect whether the outer circle runout of the casing is qualified. After the detection, the casing is transported to the gluing mechanism 22 to complete the gluing, so that the production of the rotor starts from the rotor shaft, and welding, runout detection and gluing are automatically completed, which further improves the degree of automation of rotor production. In addition, each workstation is independently arranged, and the movement of the rotor casing on each workstation is realized by a conveying device, so that the equipment at each workstation can work independently. When a single device fails, it can be taken out and replaced separately without disassembling the entire production line, thereby improving the work efficiency of maintenance personnel.

[0040] See also Figure 5 The shaft material tray 5 includes an ejection mechanism 2 and a telescopic mechanism 3. A 7-shaped ejection block 201 is arranged below the ejection mechanism 2. The tail of the ejection block 201 is located directly above the shaft material groove 501. The shaft material groove 501 is arranged between the telescopic mechanisms 3. The telescopic mechanisms 3 are two symmetrically arranged metal blocks with grooves.

[0041] The shaft material tray 5 of the present invention is used to store rotor shafts. When they need to be taken out, the telescopic mechanism 3 will take the shafts out of the shaft material tray 5 one by one, and then the ejection mechanism 2 will eject the shafts from the shaft material tray 5 from left to right to the first clamp 4, and the shafts will be clamped by the first clamp 4. The L-shaped ejection block 201 arranged below the ejection mechanism 2 is to match the shape of the shaft material groove 501. The shaft material groove 501 is a gap formed between two symmetrically arranged metal blocks with grooves by the telescopic mechanism 3. The width of the shaft material groove 501 is slightly larger than the width of the shaft, which is convenient for placing the shaft in the shaft material groove 501, allowing the shaft to remain horizontally placed in the shaft material groove 501, and the shaft will not fall from the material groove or get stuck and cannot be ejected. The grooves on the two symmetrically arranged metal blocks of the telescopic mechanism 3 are to increase friction and make it more convenient to take out the shaft.

After the first gripper 4 clamps the shaft, for the convenience of subsequent processes, it is necessary to adjust the shaft from a horizontal state to a vertical state. Therefore, the rotating motor 27 rotates to drive the first flipping mechanism 401 to flip, thereby driving the shaft clamped by the first gripper 4 to rotate and adjust it to a vertical state.

The second gripper 6 clamps the shaft sent by the first gripper 4 and is detected by the detection device arranged on the second gripper 6. After the detection, it rotates. Because the shaft is divided into upper and lower ends, one section is provided with a thread called the threaded end, and the other end is not provided with a thread. In order to facilitate subsequent pressing, the threaded end of the shaft needs to be facing upward before being sent into the pressing device 19. After the threaded end is facing upward, the shaft is placed on the base 10 of the pressing device 19. If it is detected that the threaded end is not facing upward, the second gripper 6 will not rotate.

The casing is clamped by the third clamp 8 and placed on the casing placement station 1902, and then the pressure head 1901 moves downward to press the shaft into the casing, and then the fourth clamp 9 places the casing clamping place after the shaft is pressed into the first placement place 12 of the pressing casing.

[0049] See also Figure 4 The casings that need to be pressed in the present invention all come from the casing material tray 23 arranged behind the pressing device 19. When the pressing device 19 needs a casing, the casing material tray 23 will rotate, and the casing material sub-tray 2302 with the largest number of casings currently stored will be rotated to the casing material port 2301, and the gripper installed on the second transfer device will grip the top casing of the casing material sub-tray 2302 at the casing material port 2301. After gripping the casing, the casing is transported to the back of the pressing device 19, and then the third gripper 8 arranged on the pressing device 19 will rotate to grip the casing behind the pressing device 19. , and then rotate back to place the clamped casing at the casing placement station 1902, and then the pressure head 1901 presses downward to press the shaft into the casing, and finally obtains the pressed casing.

When placed, the first placement place 12 of the pressing casing is moved to the end close to the pressing device 19 through the conveying device 28 of the pressing casing placement place, and then the fourth gripper 9 puts the shaft-entering casing on the first placement place 12 of the pressing casing. The conveying device 28 of the pressing casing placement place is provided with a slide groove, and the first placement place 12 of the pressing casing is installed on the slide groove. The sliding of the first placement place 12 of the pressing casing on the conveying devices of the pressing several placement places is realized by the slide groove. Since the laser welding equipment 20 is not connected to the pressing device 19, the first placement place 12 of the pressing casing is The placement place 12 also plays a role in direct engineering interaction between the laser welding equipment 20 and the pressing device 19. While enhancing the linkage between the two, it also ensures the independence between the two. The failure of one device will not affect the other device. Even if a failure occurs, it only needs to be repaired or directly replaced. At the same time, since each device is independent of each other and only performs engineering interaction through each transmission device, the equipment layout on the workbench 1 can be more compact, more equipment can be set up in a limited space, and more products can be produced under the same budget, which reduces the production cost of the product and improves the production efficiency of the product.

[0052] The laser welding device 20 welds the shaft to the housing to prevent the shaft from falling off.

[0053] After the shaft-entering casing is placed at the first placement position 12 of the shaft-pressing casing, the fifth gripper 11 arranged on the third conveying device 26 grips the shaft-entering casing from the first placement position 12 of the shaft-pressing casing. The fifth gripper 11 is arranged at the leftmost chute of the third conveying mechanism. Then the fifth gripper 11 rotates to transport the shaft-entering casing to the vicinity of the sixth gripper 13. The sixth gripper 13 is arranged at the second chute from left to right of the third conveying mechanism. The sixth gripper 13 grips the shaft-entering casing sent from the fifth gripper 11, and then The shell is transported to the second placement place 14 of the finalizing shell. The second placement place 14 of the finalizing shell can move forward and backward, and the shaft-entering shell placed on the second placement place 14 of the finalizing shell is transported forward to the laser welding equipment 20. The laser welding equipment 20 is provided with a welding place. When the second placement place 14 of the finalizing shell sends the shaft-entering shell to the welding place, the laser welding equipment 20 will automatically weld to weld the shaft to the shell to prevent the shaft from falling off. After the welding is completed, the second placement place 14 of the finalizing shell moves backward to take the shaft-entering shell out from the welding place.

[0054] See also Fig.10 The beating detection mechanism 21 includes a detection head 2101, and a rotating mechanism 2103 is provided on each side of the detection head 2101. The rotating mechanism 2103 is provided with a circle of grooves, and a belt 2102 is wound around the groove. A beating detection table 16 is also provided under the beating detection mechanism 21. The beating detection table 16 is used to place the detected casing. The detected casing is clamped by the eighth gripper 17, and the detected casing is transported to the gluing mechanism 22 through the third conveying device 26 connected to the eighth gripper 17.

[0055] After the welding of the shaft-entering casing of the present invention is completed, the seventh gripper 15 arranged on the third conveying mechanism will clamp the welded shaft-entering casing placed at the second placement position 14 of the shaft pressing casing. The seventh gripper 15 is arranged at the third slide slot from left to right of the third conveying mechanism. After the clamping is completed, the seventh gripper 15 transports the shaft-entering casing to the runout detection mechanism 21. The runout detection mechanism 21 is used to detect whether the outer circle runout of the casing is qualified. The runout detection mechanism 21 can move forward and backward. When detecting, the runout detection mechanism 21 will move forward to make the detected shaft-entering casing close to the runout detection mechanism 21. The belt 2102 provided in the runout detection mechanism 21 is rotated by the rotating mechanism 210 3 drives the belt 2102 to move, and fits the belt 2102 with the outer shell of the shaft-entering casing. The belt 2102 will drive the shaft-entering casing to rotate, so as to detect whether the outer circle runout of the casing is qualified. If it is detected that it is unqualified, the seventh gripper 15 will remove the shaft-entering casing from the production line. The surface of the detection head 2101 is provided with threads. During detection, the detection head 2101 will be attached to the upper surface of the shaft-entering casing. When the shaft-entering casing rotates, it will drive the detection head 2101 to rotate. If the outer circle runout of the shaft-entering casing is qualified, the detection head 2101 will rotate smoothly. If the outer circle runout of the shaft-entering casing is unqualified, the rotation of the detection head 2101 will be unsteady.

[0056] See also Fig.11 The gluing mechanism 22 includes a glue head 2202 and a gluing device 2204. The gluing device 2204 contains glue. The gluing device 2204 is connected to the gluing telescopic device 2203. The gluing mechanism 22 is also provided with a gluing position 2201 for placing the casing to be glued. A rotating mechanism 18 is also connected below the gluing position 2201. The rotating mechanism 18 can rotate the casing placed at the gluing position 2201.

[0057] After the shaft-entry casing of the present invention passes the vibration detection, the seventh gripper 15 will place the shaft-entry casing that has passed the detection on the vibration detection table 16, and then the eighth gripper 17 set on the third conveying device 26 will clamp the shaft-entry casing on the vibration detection table 16 and transport it to the gluing mechanism 22. The eighth gripper 17 is set at the rightmost slide slot of the third conveying device 26. After the eighth gripper 17 clamps the shaft-entry casing, it is turned 180 degrees to turn the shaft-entry casing over, and the turned shaft-entry casing is transported to the gluing mechanism 22 for gluing. The eighth gripper 17 places the shaft-entry casing on the gluing mechanism 22. At position 2201, when applying glue, the glue applying telescopic device 2203 performs a telescopic movement to move the glue head 2202 to the inside of the shaft entry casing, and aligns the glue head 2202 with the inner wall of the shaft entry casing. After alignment, the rotating mechanism 18 arranged directly below the glue applying position 2201 starts to rotate, and the rotating mechanism 18 drives the shaft entry casing to rotate as well. After starting to rotate, the glue applying device 2204 squeezes the internal glue to make the glue flow out from the glue head 2202 and evenly spread on the inner wall of the shaft entry casing. After the glue is evenly spread on the inner wall of the shaft entry casing for one week, the rotating casing stops rotating, and the shaft entry casing coated with glue is taken out, and the gluing work is completed.

[0058] It can be seen from the above embodiments that the present invention automatically takes out the rotor shaft by setting the shaft material tray 5, and then transports the shaft to the shaft pressing device 19 to complete the assembly of the shaft and the casing, and then transports the assembled casing to the laser welding device 20 to complete the welding of the shaft and the casing. After the welding is completed, the casing is transported to the detection device to detect whether the outer circle runout of the casing is qualified. After the detection, the casing is transported to the gluing mechanism 22 to complete the gluing, so that the production of the rotor starts from the rotor shaft, and the welding, runout detection and gluing are automatically completed, which further improves the automation of the rotor production. In addition, each station is independently set, and the movement of the rotor casing on each station is realized by the conveying device, so that the equipment at each station can work independently. When a single device fails, it can be taken out and replaced separately without disassembling the entire production line, which improves the work efficiency of the maintenance personnel. The above embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, several deformations and improvements can be made, which belong to the protection scope of the present invention.
