[0015] A. Initialization

[0016] The material grabbing and positioning system works, the positioning arm moves toward the feed side and descends into position, at which time the positioning arm is aligned with the conveyor trough; the first set of positioning fingers on the feed side is aligned with the lifter.

[0017] The track conveying system works, conveying several workpieces to the discharge side on the track and keeping them on standby.

[0021] The riveting system works, and the riveting lifting platform rises to its position and stands by.

[0022] B. Lifter loading

[0023] The positioning arm keeps in alignment with the conveying trough. When sensor I detects that the workpiece is in place, the PLC control system issues a command, and the lifter drives a workpiece to rise until the bottom of the lifter is flush with the bottom of the conveying trough.

[0024] C. Material grabbing and positioning system handling

[0025] When the material grabbing and positioning system works, its horizontal motion device translates to the discharge side at a specified spacing L, and the positioning arm drives the workpiece to translate synchronously through the positioning finger.

[0026] D. The material grabbing and positioning system assists in positioning, and each station completes the processing

[0027] At the first station, the core assembly system assembles the core into winding A. When the work at this station is completed, a completion signal is given to the control system; if sensor III does not detect the workpiece, a completion signal is directly given to the control system.

[0030] At the fourth station, the riveting system works to synchronously roughen the two ends of the iron core of the assembled workpiece. When the work at this station is completed, a completion signal is given to the control system; if the sensor VIII does not detect the workpiece, a completion signal is directly given to the control system.

[0031] E. Reset the material grabbing and positioning system

[0032] After all the completion signals given by the four workstations are sent out, the PLC control system issues a command, the vertical motion device starts working, the positioning arm rises, and the horizontal motion device starts working, driving the vertical motion device and the positioning arm to move toward the feed side at a specified interval; then the vertical motion device descends, driving the positioning arm to descend and reset.

[0033] F. Cycle steps

[0034] Repeat steps B to E above.

[0035] The advantages of the present invention are as follows: A. It can realize the automated assembly of the magnetic circuit components of the magnetic holding relay, and a series of actions are all controlled by the PLC control system. The assembly precision is high, the riveting is firm and reliable, the finished product consistency is high, and it can be automated and continuously produced, with obvious economic benefits. B. During the handling process of the robot, the positioning finger only drives the workpiece to move horizontally; the positioning finger is separated from the workpiece when it rises, and it limits the workpiece from both sides again when it descends. The positioning finger does not need to be set up with a complex matching mechanism. C. During the assembly process of each part, the positioning arm always maintains a downward posture, positioning the workpiece from above, and the positioning finger positions from both sides. The workpiece is firmly controlled, which further improves the processing precision. D.

[0046] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings.

[0047] like Figures 1 to 10 It can be seen that the fully automatic assembly production line of the magnetic circuit components of the present invention includes a rail conveying system 1 for continuously conveying workpieces in the horizontal direction; it also includes: a lifter 2 for lifting the workpieces one by one in the vertical direction; a material grabbing and positioning system 3 for transporting the workpieces to a specified position; an iron core assembly system 4 for assembling the iron core into the winding; a left choke assembly system 5 for assembling the left choke; a right choke assembly system 6 for assembling the right choke; a riveting system 7 for riveting the two ends of the iron core; and a PLC control system 8 for coordinating the operation of each system.

[0048] The rail conveying system 1 comprises a rail 10 , in which a conveying crawler belt is arranged.

[0049] The lifter 2 is arranged at the discharge end of the track conveying system 1, and includes a lifting device, a resetting device and a driving device; it also includes a sensor I matched with the lifter 2, which is used to detect whether the workpiece is located on the lifter 2.

[0050] like Figure 2 , Figure 3 , Figure 8 It can be seen that the material grabbing and positioning system 3 includes a horizontally arranged conveying trough 30, on which a core assembly station, a left yoke sheet assembly station, a right yoke sheet assembly station, and a riveting station are arranged; it also includes a horizontal motion device 32 arranged on a frame, on which a vertical motion device 33 is arranged, and the lower end of the vertical motion device 33 is connected to a positioning arm 31 matching the conveying trough 30, and the lower end surface of the positioning arm 31 is evenly spaced with a plurality of groups of positioning fingers 310.

[0051] The working process of the material grabbing and positioning system 3 is as follows: the vertical motion device 33 works, the positioning arm 31 rises, and the positioning finger 310 rises synchronously; the horizontal motion device 32 works, driving the vertical motion device and the positioning arm 31 to move toward the feeding side at a specified interval; then the vertical motion device descends, driving the positioning arm 31 to descend and contact the conveying trough 30, at which time several groups of positioning fingers 310 respectively clamp a workpiece; the horizontal motion device works, driving the positioning arm 31, the positioning finger 310 and the workpiece to move toward the discharging side at a specified interval, and after being in place, the four workpieces are aligned with the core assembly station, the left yoke iron sheet assembly station, the right yoke iron sheet assembly station, and the riveting station respectively; the material grabbing and positioning system 3 performs reciprocating motion in this way.

[0052] It should be noted that four workstations are arranged on the conveying trough 30, but for the needs of equipment layout, the conveying trough 30 is relatively long. In order to solve the problem of accurate feeding in this case, the solution adopted is: the number of groups of positioning fingers 310 is greater than the number of workstations, and each group of positioning fingers is arranged at an equal interval L. The interval between each workstation is an integer multiple of L. Every time the grabbing and positioning system 3 moves once, several workpieces are translated once according to the interval L, so that each workpiece has a chance to stop at each workstation.

[0053] The lifter 2 is matched with the material grabbing and positioning system 3. When the positioning arm 31 moves toward the feeding side and descends into position, the lifter 2 rises, and the workpiece thereon is fed into the leftmost group of positioning fingers 310, and then is limited and moved horizontally along with the positioning arm 31.

[0054] The inner side of one side of the track 10 is cut with a clearance groove for matching with the winding power pin on the winding; matching the track 10, the inner side of one side of the conveying groove 30 is also cut with a clearance groove. During the entire operation of the device, the workpiece only moves horizontally, that is, the winding power pin is always arranged along the width direction of the track 10, and the assembled iron core, yoke iron sheet and other parts are also added along the width direction of the track, and will not interfere with the winding power pin.

[0055] like Figure 4It can be seen that the core assembly system 4 matches the core assembly station; the core assembly system 4 includes a vibration plate 41, a feed trough 42, a feeder 43, a feeding cylinder 44, and an assembly cylinder 45; the feed trough 42 is arranged at the outlet of the vibration plate 41, and the width of the feed trough 42 matches the diameter of the core B; the feeder 43 is arranged at the outlet of the feed trough 42, and the feeding cylinder 44 is transmission-connected with the feeder 43; the assembly cylinder 45 matches the feeder 43; the feeder 43 and the feed trough 42 are perpendicular to each other, and the assembly cylinder 45 and the feed trough 42 are parallel to each other.

[0056] It also includes a sensor II matched with the feeder 43, which is used to detect whether the iron core as an accessory is in place.

[0057] It also includes a sensor III matched with the core assembly station, which is used to detect whether the workpiece on the core assembly station is in place.

[0058] The working process of the iron core assembly system 4 is as follows: the vibration plate 41 vibrates continuously, and the iron core B is conveyed into the feed trough 42 in a lying posture, at which time the iron core B is parallel to the feed trough 42; when the iron core B is separated from the feed trough 42, the feeding cylinder 44 drives the feeder 43 to move, and the iron core B moves horizontally; then the assembly cylinder 45 works, and its ejector pin presses the iron core B to make it move axially and press it into the inner cavity of the winding A.

[0059] like Figure 4 It can be seen that the core assembly system 4 is also provided with a guide plate 46 for guiding the feeder 43 , and the guide plate 46 is provided with two through holes for passing the core B and the piston rod of the assembly cylinder 45 , respectively.

[0060] like Figure 3 It can be seen that the left choke assembly system 5 and the right choke assembly system 6 are respectively arranged on both sides of the material grabbing and positioning system 3; the left choke assembly system 5 assembles a choke on the winding skeleton from one side of the material grabbing and positioning system 3, and inserts a free end of the core B into the core positioning hole of the choke. The right choke assembly system 6 assembles the choke to the winding A from the other side of the material grabbing and positioning system 3, and inserts the other free end of the core B into the core positioning hole of the choke.

[0061] like Figure 3 , Figure 5It can be seen that the left choke assembly system 5 matches the left choke assembly station; the left choke assembly system 5 includes a choke vibration plate 51, a choke feed trough 52, a choke positioner 53, and a choke assembly cylinder 54. The choke feed trough 52 is arranged at the outlet of the choke vibration plate 51, the choke feed trough 52 is connected to the choke positioner 53 via a transition track 530, the choke positioner 53 is connected to the feeding notch arranged on the conveying trough 30 via a yoke feeding track 531, and the piston rod of the assembly cylinder 54 passes through the choke positioner 53 and extends into the yoke feeding track 531. The choke feed trough 52, the transition track 530 and the conveying trough 30 are arranged in parallel, and the assembly cylinder 54 and the yoke feeding track 531 are arranged vertically to the conveying trough 30.

[0062] It also includes a sensor IV matched with the yoke piece positioner 53, which is used to detect whether the yoke piece as an accessory is in place; it also includes a sensor V matched with the left choke piece assembly station, which is used to detect whether the workpiece is located at the left choke piece assembly station.

[0063] The choke vibration plate 51 adjusts the posture of the left choke C, and conveys the yoke with the required posture to the choke feed trough 52; the required posture is a standing posture, that is, the core positioning hole is at the top, the pin is at the bottom, and the pin of the choke is on the side of the conveying trough 30 of the material grabbing and positioning system 3; the choke feed trough 52 conveys the left choke C to the choke positioner 53 in a translational manner via the transition track 530, and then the choke assembly cylinder 54 works, and the piston rod drives the punch to impact the left choke, so that it translates into the work station along the loading track 531 in a direction perpendicular to the conveying trough 30, and is assembled on the winding frame under the action of the impact force, and a free end of the core B is inserted into the core positioning hole of the choke. The root of the yoke sheet feeding track 531 is provided with a clearance groove matching the pins of the yoke sheet along its length direction. When the yoke sheet moves along the feeding track 531, the pins of the yoke sheet are always restricted by the clearance groove, so that they only move horizontally and will not flip.

[0064] like Fig. 9 , Fig.10It can be seen that the choke plate vibration disk 51 includes a spiral vibration conveying track, and the choke plate feeding trough 52 is arranged at the outlet of the spiral vibration conveying track. The starting end of the choke plate feeding trough 52 is arranged as a cavity with a "└"-shaped cross section, and the ending end is arranged as a cavity with a "┘"-shaped cross section, and there is a gradual transition between the starting end and the ending end; the cavity matches the yoke plate. When the yoke plate is conveyed to the starting end, the yoke plate in a flat posture with the pins on top enters the choke plate feeding trough 52, and the one that does not meet the requirements falls into the disk again. The yoke plate is gradually adjusted in posture through the choke plate feeding trough 52, and is finally conveyed to the workstation in a posture that meets the assembly requirements.

[0065] like Figure 6 It can be seen that the right choke assembly system 6 matches the right choke assembly station; the structure and working principle of the right choke assembly system 6 are the same as those of the left choke assembly system 5; specifically, the right choke assembly system 6 includes a right choke vibration plate 61, a right choke feeding trough 62, a right choke positioner 63, and a right choke assembly cylinder 64. It also includes a sensor VI matched with the right choke positioner 63, which is used to detect whether the yoke sheet as an accessory is in place; it also includes a sensor VII matched with the right choke assembly station, which is used to detect whether the workpiece is located at the right choke assembly station.

[0066] Along the length direction of the material grabbing and positioning system 3, the positions of the left choke assembly system 5 and the right choke assembly system 6 are not required to be in front and behind; Figure 2 , Figure 3 It can be seen that in this embodiment, the corresponding workstation of the left choke assembly system 5 is at the rear, and the corresponding workstation of the right choke assembly system 6 is at the front.

[0067] like Figure 2 , Figure 3 It can be seen that three notches are arranged on both sides of the conveying trough 30 of the material grabbing and positioning system 3, which respectively match the piston rods of the assembly cylinder 45, the choke assembly cylinder 54 and the right choke assembly cylinder 64, and are used to convey accessories from the side of the conveying trough 30 in the vertical direction.

[0068] The riveting system 7 is used to synchronously upset the two free ends of the assembled iron core B so that the iron core B and the left choke piece C and the right choke piece D fit tightly.

[0069] like Figure 7It can be seen that the riveting system 7 includes left and right sliders 70, 70' matching the riveting station, and also includes a riveting platform 71 fixed on the frame, a riveting power cylinder 72 is arranged above the riveting platform 71, and a riveting lifting platform 73 is movably arranged below through a guide device, and the piston rod of the riveting power cylinder 72 is connected to the riveting lifting platform 73 by transmission; the left and right inclined wedge components 730, 730' are symmetrically arranged below the riveting lifting platform 73, and the left and right sliders 70, 70' are matched with guide holes; the left and right sliders 70, 70' are provided with a reset device. It also includes a matching sensor VIII matching the riveting station for detecting whether the workpiece is in place.

[0070] Working process of riveting system 7: the material grabbing and positioning system 3 transports the workpiece to the riveting station, the riveting power cylinder 72 works, the riveting lifting platform 73 impacts downward, and the left and right inclined wedge components 730, 730' wedge into the guide holes on the left and right sliders 70, 70', so that the left and right sliders 70, 70' shrink toward the middle synchronously, and impact the iron core B from both sides respectively, and roughen its end. When the operation is completed, the riveting lifting platform 73 moves up, and the left and right sliders 70, 70' are reset; the rear end of the riveting system 7 is matched with a finished product discharge trough 9 arranged in a vertical direction. The roughened workpiece is pushed to the finished product discharge trough 9 and discharged when the positioning arm 31 moves horizontally for the next time.

[0071] like Figure 7 It can be seen that the riveting system 7 also includes a booster cylinder 720 connected to the riveting power cylinder 72 for boosting the riveting power cylinder 72 .

[0072] The overall working process of this magnetic circuit component fully automatic assembly production line is:

[0073] Note on the expression method: In the following description, accessories refer to yoke iron sheets and iron cores; workpieces refer to winding A entering from the track conveying system 1, and winding A after gradually assembling various accessories continues to be called workpiece.

[0074] A. Initialization

[0075] The material grabbing and positioning system 3 works, the positioning arm 31 moves toward the feeding side and descends into position, at which time the positioning arm 31 is aligned with the conveying trough 30 ; the first group of positioning fingers 310 on the feeding side is aligned with the lifter 2 .

[0076] The track conveying system 1 is in operation, conveying a plurality of workpieces to the discharge side on the track 10 and keeping them on standby.

[0077] The vibrating plate 41 of the core assembly system 4 vibrates continuously to convey the core B in a flat position to the feeding trough 42 to wait.

[0078] The choke piece vibration plate 51 of the left choke piece assembly system 5 works to adjust the yoke piece and then transport it to the choke piece positioner 53 and wait.

[0080] The riveting system 7 works, and the riveting lifting platform 73 rises to its position and stands by.

[0081] B. Lifter 2 loading

[0082] The positioning arm 31 is kept in a matching state with the conveying trough 30. When the sensor I detects that the workpiece is in place, the PLC control system 8 issues a command, and the lifter 2 drives a workpiece to rise until the bottom of the lifter 2 is flush with the bottom of the conveying trough 30. In this step, the workpiece is restricted in the vertical direction by the top of the positioning arm 31, and in the horizontal direction by a group of positioning fingers 310 from the left and right sides.

[0083] C. Material grabbing and positioning system handling

[0084] The material grabbing and positioning system 3 works, and its horizontal motion device 32 translates toward the material discharging side at a specified spacing L, and the positioning arm 31 drives the workpiece to translate synchronously through the positioning finger 310; since the spacing between each station is an integer multiple of L, it can be ensured that the workpiece can be aligned with each station after translation.

[0085] During the operation of the present invention, the positioning finger 310 only drives the workpiece to move horizontally; the positioning finger 310 separates from the workpiece when rising, and limits the workpiece from both sides again when descending. The positioning finger 310 does not need to be provided with a complex matching mechanism.

[0086] D. The material grabbing and positioning system assists in positioning, and each station completes the processing

[0087] The material grabbing and positioning system 3 has a fixed posture, that is, during the processing, the positioning arm 31 always covers the top of the conveying trough 30, which can play a role in auxiliary positioning.

[0088] At the first workstation (core assembly workstation), the core assembly system 4 assembles the core B into the winding A.

[0089] Specifically: sensor II detects that the iron core B as an accessory is in place, the feeding cylinder 44 drives the feeder 43 to move, and the iron core B moves horizontally to the front end of the piston rod of the assembly cylinder 45; sensor III detects that the workpiece is located at the iron core assembly station, and the PLC control system 8 sends an operation instruction to the assembly cylinder 45 to assemble the iron core B into the winding A.

[0090] When the work at this station is completed, a completion signal is given to the control system; if sensor III does not detect the workpiece, a completion signal is directly given to the control system.

[0091] At the second station (left choke piece assembly station), the left choke piece assembly system 5 assembles a yoke piece onto the winding A from the side of the positioning arm 31 .

[0092] Specifically: sensor IV detects that the yoke piece as an accessory is in place, sensor V detects that the workpiece is in place, the PLC control system 8 sends an operation instruction to the yoke piece assembly cylinder 54, the operation of this workstation is completed, and a completion signal is given to the control system; if sensor V does not detect the workpiece, a completion signal is directly given to the control system.

[0093] At the third station (right choke piece assembly station), the right choke piece assembly system 6 assembles a yoke piece onto the winding A from the other side of the positioning arm 31 .

[0094] Specifically: sensor VI detects that the yoke piece as an accessory is in place, sensor VII detects that the workpiece is in place, the PLC control system 8 sends an operation instruction to the right yoke piece assembly cylinder 64, the operation of this workstation is completed, and a completion signal is given to the control system; if sensor VII does not detect the workpiece, a completion signal is given to the control system.

[0095] At the fourth station (riveting station), the riveting system 7 works to synchronously upset the two ends of the iron core B of the assembled workpiece.

[0096] Specifically: sensor VIII detects that the workpiece is in place, the PLC control system 8 sends an operation command to the riveting power cylinder 72, the riveting lifting platform 73 impacts downward, the left and right inclined wedge components 730, 730' are wedged into the guide holes on the left and right sliders 70, 70', so that the left and right sliders 70, 70' are synchronously contracted toward the middle, respectively impacting the iron core B from both sides to roughen its end.

[0097] When the work at this workstation is completed, a completion signal is given to the control system; if sensor VIII does not detect the workpiece, a completion signal is directly given to the control system.

[0098] In this step, the workpiece remaining in the riveting station in the previous operation cycle is pushed to the finished product discharge chute 9 by the positioning arm 31 and unloaded.

[0099] E. Reset the material grabbing and positioning system

[0100] After all the completion signals given by the four workstations are sent out, the PLC control system 8 issues a command, the vertical motion device 33 works, the positioning arm 31 rises, and the horizontal motion device 32 works, driving the vertical motion device and the positioning arm 31 to move toward the feed side at a specified interval; then the vertical motion device descends, driving the positioning arm 31 to descend and reset.

[0101] F. Cycle steps
