[0042] The material grabbing manipulator conveying line 3 is composed of multiple groups of manipulator conveying mechanisms 31, each group of the manipulator conveying mechanisms 31 includes a mounting beam, a rodless conveying cylinder horizontally mounted on the mounting beam, a mounting plate horizontally slidably fitted on the mounting beam and driven to move by the rodless conveying cylinder, multiple lifting cylinders vertically and invertedly mounted on the mounting plate, and multiple finger cylinders mounted on the piston rods of the lifting cylinders, the finger cylinders being used to clamp the motor housing. The feeding device 2 is used to place the power supply housing 101 and transport the motor housing. The compression spring and bearing pressing device 4 is arranged on the side of the discharge position of the feeding device 2, receives the motor housing 102 transmitted to the discharge position from the feeding device 2 through the conveyance of the finger cylinder, and presses the compression spring and bearing into the inner bottom of the motor housing. The orientation positioning device 5 is arranged on the side of the discharge position of the compression spring and bearing pressing device 4, receives the motor housing with the compression spring and bearing pressed through the conveyance of the finger cylinder, and drives the motor housing to rotate around its center line to the desired orientation. The magnetic tile and retaining spring pressing device 6 is arranged on the side of the discharge position facing the positioning device 5, and receives the motor housing after positioning through the conveyance of the finger cylinder, and presses the magnetic tile and retaining spring into the motor housing. The magnetizing device 7 is arranged on the side of the discharge position of the magnetic tile and retaining spring pressing device 6, and receives the motor housing with the magnetic tile and retaining spring pressed through the conveyance of the finger cylinder, and magnetizes the motor housing. The flipping device 8 is arranged on the side of the discharge position of the magnetizing device 7, and receives the motor housing with the magnetized magnetic tile through the conveyance of the finger cylinder, and flips the motor housing 180 degrees up and down. The discharging device 9 is arranged on the side of the discharge position of the flipping device 8, and receives the flipped motor housing through the conveyance of the finger cylinder, and provides the motor housing for discharging and storage.

[0043] Based on the above structure, the motor housing is transported between the devices through the manipulator transport mechanism 31, that is, the motor housing on the discharge position of each device is transported to the loading position of each next device. In the above process, through the cooperation between the various devices, the compression spring, bearing, magnetic tile and retaining spring are inserted into the motor housing in the form of an assembly line, and the magnetic tile can also be magnetized at the same time. Finally, the motor housing after magnetization is stored, which significantly improves the convenience and efficiency of motor housing assembly, and can also reduce labor costs.

[0044] Specific as Figure 2As shown: the feeding device 2 includes a feeding conveyor belt 21, a discharging conveyor belt 22 and a guide plate 24; the feeding conveyor belt 21 and the discharging conveyor belt 22 are arranged side by side and in opposite directions; the guide plate is arranged above the feeding conveyor belt 21 and the discharging conveyor belt 22 at the same time, and the guide plate has a guide surface 241 that can guide the motor housing at the tail end of the feeding conveyor belt 21 to the head end of the discharging conveyor belt 22. The feeding conveyor belt 21 and the discharging conveyor belt 22 are respectively transmitted through the rollers and motors 28 / 29 connected to them; the feeding device 2 has the characteristics of compact structure and can conveniently provide motor housings for the entire assembly machine; the feeding device 2 is divided into a feeding conveyor belt 21 and a discharging conveyor belt 22, which can not only increase the amount of motor housings put in, but also realize the neat supply of motor housings. On the other hand, the putting-in end and the discharging position of the motor housing can be located at the same end of the entire feeding device 2, which is convenient for observing the motor housing at the discharging position when loading.

[0045] The feeding device 2 is further configured as follows: the width of the discharge conveyor belt 22 is only enough for one motor housing to pass through, and the width of the feed conveyor belt 21 is greater than the width of the discharge conveyor belt 22. Under this structure, the motor housings are conveyed in a single row in the discharge conveyor belt 22 to ensure the neatness of the arrangement of the motor housings; the widening of the feed conveyor belt 21 can increase the amount of motor housings placed on the feed conveyor belt 21, making it easier for operators to load materials.

[0046] A positioning plate 26 is provided at the tail end of the discharging conveyor 22, and the positioning plate 26 has a positioning groove 261 for the motor housing to enter. When the motor housing is conveyed to the tail end of the discharging conveyor 22, the motor housing will enter the positioning groove to achieve positioning for accurate grasping by the finger cylinder.

[0047] A partition 23 is provided between the feed conveyor belt 21 and the discharge conveyor belt 22, and a motor housing passage 25 is formed between one end of the partition 23 corresponding to the guide surface 241 and the guide surface 241. This structure can avoid the problem of interference between the motor housings on the feed conveyor belt 21 and the discharge conveyor belt 22, and improve the stability of the motor housing transportation.

[0048] A sensor 27 is provided at the discharge position of the discharge conveyor belt 22 to sense the motor housing entering the positioning groove so that the finger cylinder can grab the motor.

[0049] like Figure 3-5As shown, the compression spring and bearing press-fitting device 4 is further configured as follows: the compression spring and bearing press-fitting device 4 includes a turntable 41, a carrier tool 46, a press-fitting tool 42, a compression spring feeding assembly 43 and a bearing feeding assembly 44; the turntable 41 is arranged on the workbench 1; the carrier tool 46 has five and is evenly arranged on the turntable 41 in a circumferential manner, and sequentially forms a press-fitting upper position 414, a press-fitting position 415, a press-fitting discharge position 411, a compression spring loading position 412 and a bearing loading position 413 in the direction of rotation. The compression spring feeding assembly 43 corresponds to the compression spring loading position 412 to provide a compression spring to the carrier tool 46 on the compression spring loading position 412. The bearing feeding assembly 44 corresponds to the bearing loading position 413 to provide a bearing to the carrier tool 46 on the bearing loading position 413. The press-fitting loading position 414 corresponds to the discharge position of the feeding device 2, and the motor housing 102 on the discharge position of the feeding device 2 can be transported to the press-fitting loading position 414 by the manipulator transport mechanism 31. The press-fitting tool 42 corresponds to the press-fitting position 415, and presses down the motor housing on the carrier tool 46 transferred to the press-fitting position 415, so that the compression spring 30 and the shaft 20 on the carrier tool 46 are pressed into the inner bottom wall of the motor housing 103.

[0050] Specific as Figure 5 As shown, the carrier tooling 46 includes a positioning column 461 installed on the turntable 41 by bolts, a compression spring fixed to the top of the positioning column 461 by a pressure ring 462 and a bearing positioning core 464, and the pressure ring 462 is installed on the top of the positioning column 461 by bolts 463.

[0051] The compression spring feeding assembly 43 and the bearing feeding assembly 44 both include a vibration plate 434, a material distribution assembly 431 / 442 and a feeding manipulator 441 / 432 installed on the workbench 1. The vibration plate 434 feeds the compression spring or the retaining spring into the straight vibration groove 433 / 443 of the material distribution assembly 431 / 442 through the discharge channel, and then feeds it into the groove 4331 of the positioning block of the material distribution assembly 431 / 442; the feeding manipulator 441 / 432 grabs the retaining spring or the bearing, and then transports the grabbed retaining spring or the bearing to the positioning core 464.

[0052] The loading robot 441 / 432 includes a frame 451 installed on the workbench 1, a horizontal moving block 454 that can be horizontally moved and matched with the top of the frame 451 through a cylinder 452 and a guide rod, a lifting moving block 456 that can be raised and lowered and matched with the horizontal moving block 454 through a cylinder 453 and a guide rod, and a positioning sleeve 457 arranged on the lifting moving block 456. The lower port 4571 of the positioning sleeve 457 can be used for the bearing to be embedded. At the same time, an embedding portion 4572 that can be embedded in the center hole of the compression spring is formed on the lower end of the positioning sleeve 457. A ejecting cylinder 455 is also installed on the lifting moving block 456. The ejecting cylinder 455 is an inverted structure. The piston rod of the ejecting cylinder 455 passes through the lifting moving block 456 and enters into the positioning sleeve 457, which can eject the bearing embedded in the lower port of the positioning sleeve 457, or eject the compression spring stuck on the embedding portion 4572.

[0053] The press-fitting tool 42 comprises a press-fitting cylinder and a press block 421 . The press-fitting cylinder is mounted on the frame of the workbench 1 , and the press block 421 is mounted on the piston rod of the cylinder.

[0054] During operation, the turntable 41 rotates, so that the various workstations on the turntable 41 are replaced, and the vibration disk 434 in the compression spring feeding assembly 43 provides compression springs to feed the grooves on the positioning blocks of the material distribution assembly 443 / 433. The corresponding cylinder 452 drives the horizontal moving block 454 to move above the groove, and the corresponding cylinder 453 drives the lifting moving block 456 and the positioning sleeve 457 to move downward, so that the embedded portion 4572 on the positioning sleeve 457 is clamped into the center hole of the compression spring, and then the corresponding cylinder 453 drives the positioning sleeve 457 to move upward, and the corresponding cylinder 452 drives the positioning sleeve 457 to move horizontally to above the compression spring installation position 412, and the corresponding cylinder 453 drives the positioning sleeve 457 to move downward so that the lower end of the positioning sleeve 457 contacts the positioning core 464, and the ejecting cylinder 455 is started to push the compression spring away from the embedded portion 4572 and drop it onto the positioning core 464. The turntable 41 rotates, so that the carrier tooling 46 equipped with a compression spring rotates to the bearing installation position 413, and the bearing feeding assembly 44 feeds the bearing to the positioning core 464 in the same principle as the compression spring feeding assembly 43. The only difference is that a pressing cylinder corresponding to the groove 4331 is provided on the lower surface of the positioning block of the bearing feeding assembly 44. When the positioning sleeve 457 moves to the top of the bearing located in the groove, the pressing cylinder presses the bearing upward into the lower port of the positioning sleeve 457. After the carrier tooling 46 is installed with the bearing, it is transferred to the press-fitting loading position 414, and the finger cylinder grabs the motor housing on the feeding device 2 and sets it on the carrier tooling 46. The turntable 41 drives the carrier to rotate to the pressing position 415, and the pressing cylinder in the pressing tool 42 drives the pressing block 421 to press down, and the pressing block 421 presses down the motor housing, so that the compression spring and the bearing on the top of the positioning core 464 are stuck to the inner top wall of the motor housing in this working position; the turntable 41 continues to rotate, driving the pressed motor housing to rotate to the pressing discharge position 411 for the finger cylinder to grab.

[0055] like Figure 6As shown, the orientation positioning device 5 is further configured as follows: the orientation positioning device 5 includes a positioning mechanism, a pushing mechanism 58 and a rotating mechanism 57. The positioning mechanism includes a positioning ring 51 and an elastic positioning pin assembly 55; the positioning ring 51 can be loaded into the motor housing; the elastic positioning pin assembly 55 is arranged on the side wall of the positioning ring 51, and the end of the positioning pin 552 in the elastic positioning pin assembly can be inserted into the opening 1031 on the motor housing; the pushing mechanism has a positioning loading position 562 and a rotation orientation position 561, the pushing mechanism is used to fix the positioning ring 51, and can drive the positioning ring 51 to move between the positioning loading position 562 and the rotation orientation position 561; the rotating mechanism 57 corresponds to the rotation orientation position 561 up and down, and can drive the motor housing located in the positioning ring 51 to rotate, so that the opening of the motor housing corresponds to the elastic positioning pin assembly 55. Under the above structure, the finger cylinder grabs the motor housing on the press-fit discharge position 411 into the positioning ring 51 at the positioning loading position 562; the pushing mechanism 58 drives the positioning ring 51 and the motor housing to move to the rotation orientation position 561; the rotating mechanism 57 drives the motor housing on the rotation orientation position 561 to rotate; during the rotation of the motor housing, when the opening on the side wall of the motor housing does not correspond to the elastic positioning pin assembly 55, the elastic positioning pin assembly 55 is in a compressed state, and when the opening 1031 on the side wall of the motor housing corresponds to the end of the elastic positioning pin assembly 55, the end of the elastic positioning pin assembly 55 can be ejected into the opening, thereby positioning the direction of the motor housing, and has the characteristics of simple structure and precise positioning.

[0056] The elastic locating pin assembly includes a fixing sleeve 551, a locating pin 552 and a spring 553; the fixing sleeve 551 is fixed on the outer surface of the locating ring 51; the locating pin is slidably fitted in the fixing sleeve 551, and the end of the locating pin can pass through the locating ring 51 and enter the locating ring 51; the spring is arranged between the locating pin and the fixing sleeve 551, and pushes the end of the locating pin toward the inside of the locating ring 51.

[0057] Specifically, two ends of the spring respectively abut against the inner step of the fixing sleeve 551 and the outer step of the positioning pin.

[0058] A guide groove is provided on the side wall of the fixing sleeve 551 , and a guide pin is provided on the side wall of the positioning pin. The guide pin fits in the guide groove to ensure the stability of the movement of the positioning pin.

[0059] A rotating shaft 54 ​​is installed in the center hole of the positioning ring 51 through a bearing 53, and a rotating plate 52 supported by the power supply housing is connected to the top of the rotating shaft 54. This structure can facilitate the rotation of the motor housing; in this structure, the bearing is supported on the inner step of the center hole.

[0060] The rotating mechanism includes a cylinder and a motor installed in an inverted state on a frame of a workbench. The piston rod of the cylinder is connected to a rotating shaft through a thrust bearing. A rotating sleeve is connected to the lower end of the rotating shaft. At the same time, the rotating shaft is connected to the motor through gears and belts. Therefore, the cylinder can drive the rotating sleeve to be mounted on the motor housing. The motor drives the rotating sleeve to rotate through the rotating shaft, thereby driving the motor housing to rotate.

[0061] like Figure 7-12 As shown, the magnetic shoe and retaining spring pressing device 6 is further configured as follows: the magnetic shoe and retaining spring pressing device 6 includes a push-pull mechanism, the push-pull mechanism has a component pressing upper material position b and a component pressing position a, and can drive the motor housing to move between the component pressing upper material position b and the component pressing position a; a secondary pushing mechanism 61, which is movably arranged below the component pressing position a, and has a magnetic shoe loading position 611 and a retaining spring loading position 612 at the top of the secondary pushing mechanism 61; a magnetic shoe feeding mechanism 62 and a retaining spring feeding mechanism 63, both of which have a supply Material channel, and through the feed channel respectively correspond to the magnetic tile loading position 611 and the retaining spring loading position 612, so as to provide magnetic tiles and retaining springs for the magnetic tile loading position 611 and the retaining spring loading position 612; the pushing drive mechanism 65 is connected to the lower end of the secondary pushing mechanism 61 to drive the secondary pushing mechanism 61 to move up and down. When the secondary pushing mechanism 61 moves upward, the top of the secondary pushing mechanism 61 can enter into the motor housing 104 located at the component pressing position a, and press the magnetic tile 30 on the magnetic tile loading position 611 and the retaining spring 40 on the retaining spring loading position 612 into the motor housing 104. During the specific operation, the finger cylinder will grab the motor housing that has been oriented on the positioning device 5 and grab it to the component pressing and loading position b; the push-pull mechanism drives the motor housing with the opening facing downward to move to the component pressing position a; the magnetic tile feeding mechanism 62 and the retaining spring feeding mechanism 63 provide magnetic tiles and retaining springs to the magnetic tile loading position 611 and the retaining spring loading position 612 respectively; the pushing drive mechanism 65 drives the secondary pushing mechanism 61 to move upward, and pushes the magnetic tiles on the magnetic tile loading position 611 and the retaining spring on the retaining spring loading position 612 into the motor housing, and the pushing drive mechanism 65 drives the secondary pushing mechanism 61 to move downward, and the magnetic tiles and retaining springs can be pressed into the motor housing; it should be noted that when the magnetic tiles and retaining springs are clamped into the motor housing, the magnetic tiles and retaining springs are in a clamped state, so when the secondary pushing mechanism 61 moves downward, the magnetic tiles and retaining springs will not be brought out of the motor housing.

[0062] Specifically, the push-pull mechanism includes a bracket 641 and a push-pull cylinder assembly 642; the top of the bracket 641 is a slide groove 6411 for moving the power supply housing, the component pressing position b and the component pressing position a are respectively located at the two ends of the slide groove 6411, and the bottom wall of the slide groove 6411 corresponding to the component pressing position a is opened; the push-pull cylinder assembly 642 includes a press-fit push-pull cylinder 6422 and a positioning plate 6421; the positioning plate 6421 has a press-fit positioning groove for positioning the power supply housing 104, and the press-fit push-pull cylinder 6422 is connected to the positioning plate 6421 to drive the positioning plate 6421 to move in the slide groove 6411, thereby driving the motor housing to move between the component pressing position b and the component pressing position a.

[0063] like Fig. 9 , 11 As shown, a plurality of support plates 6412 are provided on the lower side of the bracket 641 corresponding to the slide groove 6411, and a press-fit slide 6413 for limiting the secondary pushing mechanism 61 is formed between the support plates 6412. The upper port of the press-fit slide 6413 is connected to the opening on the bottom wall of the slide groove 6411, and the inner wall of the press-fit slide 6413 is provided with a guide plate 64121 / 64122 matched with the back shape of the magnetic tile and the retaining spring to play a role of limiting and guiding the magnetic tile and the retaining spring.

[0064] A fixing frame 651 is provided above the component pressing position a corresponding to the slide groove 6411, and a pressing cylinder 652 is arranged on the fixing frame 651. A pressing plate is connected to the piston rod of the pressing cylinder 652. When the magnetic tile and the retaining spring are pressed into the motor housing, the pressing cylinder drives the pressing plate to press on the motor housing 104 to ensure the stability of the pressing of the magnetic tile and the retaining spring.

[0065] The magnetic tile feeding mechanism 62 and the snap spring feeding mechanism 63 both include a feeding channel; there are feeding ports on the side walls of the support plate 6412, and the positions of the four feeding ports are respectively connected with the two magnetic tile loading positions 611 and the two snap spring loading positions 612 when the secondary pushing mechanism 61 is in the downward state, and the discharge end of the feeding channel is connected with the feeding port. Under this structure, the magnetic tile or snap spring in the feeding channel can be transferred to the magnetic tile loading position 611 and the snap spring loading position 612, so that the secondary pushing mechanism 61 can be pushed into the motor housing 104.

[0066] The two magnetic tile installation positions 611 are symmetrically located on the secondary pushing mechanism 61, and the two spring installation positions 612 are also symmetrically arranged on the secondary pushing mechanism 61, so there are two feeding channels in the magnetic tile feeding mechanism 62 and the spring feeding mechanism 63. The two feeding channels 621 / 622 of the magnetic tile feeding mechanism 62 each include a magnetic tile conveyor belt 6221 driven by a motor, a feeding channel 6222 / 62111 connected to the tail end of the magnetic tile conveyor belt 6221, and a reversing component 623 that transfers the magnetic tile at the tail end of the magnetic tile conveyor belt 6221 to the feeding channel 6222 / 62111. This arrangement enables the two magnetic tile conveyor belts 6221 in the magnetic tile feeding mechanism 62 to be arranged on the same side, so as to facilitate the provision of magnetic tiles on the same side.

[0067] The reversing assembly 623 includes a feed motor 6231 and a feed cylinder 6233; the feed motor 6231 and the feed cylinder 6233 are both inverted and arranged on a frame on the workbench 1; the feed cylinder 6233 is connected to a feed shaft 6232 via a thrust bearing seat; an adsorption iron block 6234 is arranged at the lower end of the feed shaft 6232, and the feed shaft 6232 is docked with the tail end of the magnetic tile conveyor belt 6221; the feed motor 6231 is connected to the feed shaft 6232 via gears and belts; the feed channel 6222 / 62111 is arranged below the feed shaft 6232. Specifically, of the two feed channels of the magnetic tile feeding mechanism 62, one of them can feed in the same direction, and the other needs to be fed by 180 degrees through the reversing assembly 623 and the feed channel 6222.

[0068] The structure of the feeding channel 622 in the magnetic shoe feeding mechanism 62 that requires 180-degree reversing feeding is as follows: its feeding channel 6222 is an L-shaped structure, divided into a first channel 62221 perpendicular to the magnetic shoe conveyor belt 6221 and a second channel 62222 perpendicular to the first channel 62221, and a magnetic shoe reversing opening 50 for the magnetic shoe to be inserted is provided on the side wall of the first channel 62221 corresponding to the feeding shaft 6232. The adsorption iron block 6234 adsorbs the magnetic tile 60 at the tail end of the magnetic tile conveyor belt 6221, and the feeding motor 6231 drives the feeding shaft 6232 to rotate, driving the magnetic tile to rotate 180 degrees, and the feeding cylinder 6233 drives the reversed magnetic tile to move downward. When the feeding shaft 6232 passes through the magnetic tile reversing port 50 of the first channel 62221, the magnetic tile is clamped in the magnetic tile reversing port and is located in the first channel 62221. A pushing cylinder is provided on one end of the first channel 62221 to push the magnetic tile entering the first channel 62221 to the second channel 62222 which is perpendicular to the first channel 62221. The second channel 62222 also uses a pushing cylinder to push the magnetic tile to push the magnetic tile through the feeding port and into the magnetic tile loading position 611.

[0069] like Fig.10As shown, the structure of the feeding channel 621 that does not require reversing in the magnetic tile feeding mechanism 62 is: the feeding channel 62111 extends in the same direction as the magnetic tile conveyor belt 6221, and the feeding channel 6222 is below the magnetic tile conveyor belt 6221, the adsorption iron block 6234 adsorbs the magnetic tiles at the tail end of the magnetic tile conveyor belt 6221, the feeding cylinder 6233 drives the magnetic tiles to move downward into the feeding channel 62111, the feeding motor 6231 drives the feeding shaft 6232 to rotate, so that the raised adsorption part on the adsorption iron block 6234 is separated from the magnetic tiles, the feeding cylinder 6233 moves upward, and the pushing cylinder at the end of the feeding channel 62111 pushes the magnetic tiles through the feeding port into the magnetic tile loading position 611.

[0070] Since the clamping spring is light in weight, the feeding channel in the clamping spring feeding mechanism 63 can be transmitted using the straight vibration groove 631. The clamping spring is stored in the vibration plate 632, and the vibration plate 632 transmits the vibration of the clamping spring to the straight vibration groove 631, and the discharge port of the straight vibration groove is connected with the feeding port to directly play a feeding role.
