[0041] The static contact unloading station 21 includes a vibration plate, a feeding track and a mechanical clamp; first, the static contact 10 is fed to the position of the mechanical clamp by the vibration plate and the feeding track, and then the mechanical clamp clamps the static contact 10 and places it in the static contact assembly groove 32; at this time, the frame 1 is provided with a telescopic rod located behind the mounting seat, and the telescopic rod moves the first clamp seat 35 forward through the guide rod 38, so that the static contact 10 can be smoothly placed in the assembly groove, and then when the turntable rotates, the first clamp seat 35 will be separated from the telescopic rod, so that the first clamp seat 35 will clamp the static contact 10; and a groove corresponding to the contact point on the static contact is provided on the side of the first clamp seat 35 that abuts against the static contact, and the groove can avoid damage to the contact point;
[0042] At the same time, a visual detector for detecting the contact points on the stationary contact 10 is also arranged on the feeding track.
[0043] Then the turntable rotates, and the mounting seat rotates to the magnetic bracket unloading station 22, and the magnetic bracket is transported forward under the action of the vibration plate and the feeding track, and then the mechanical clamp will clamp the magnetic bracket and put it into the magnetic bracket assembly slot 33; then the turntable continues to rotate and passes through the detection mechanism, and the pressure rod on the detection mechanism presses the magnetic bracket and the static contact downward, so that the welding position of the magnetic bracket and the static contact is aligned; and if the pressure rod does not press the static contact or the magnetic bracket, the photoelectric sensor on the detection mechanism will send a signal;

[0046] The core coil unloading station includes two vibration plates, which are used to transport the core assembly and the coil respectively. First, the coil will be clamped by the first mechanical gripper and the direction will be changed. Then, the second mechanical gripper will clamp the coil and place it on the coil seat 2412 of the processing table 241. Then, the coil seat 2412 will limit the position of the coil. Then, the fixing clamps 2413 on both sides will clamp the coil under the push of the cylinder.
[0047] Then, the core assembly 8 is delivered to the feeding seat 2430 under the action of the feeding track 2436. Figure 5-6 As shown, a driving block 2431 connected to a cylinder is slidably provided on the feeding seat 2430, and a clamping groove 2432 is provided on the driving block 2431. The clamping groove 2432 corresponds to the feeding track 2436 and is used to place the core assembly 8; it also includes a discharge hole 2433 arranged at the bottom of the feeding seat 2430 and located below the driving block 2431, and the discharge hole 2433 is connected to the feed port of the pushing pipe 2415 through a feeding pipe 2434; when the cylinder drives the clamping groove 2432 of the driving block 2431 to reach above the discharge hole 2433, the core assembly 8 falls into the discharge hole 2433, and then is sent to the pushing seat 2414 through the feeding pipe 2434, as shown in FIG. Figure 8-9As shown, a feed port is provided on the push seat 2414, and the feed port is connected to the push pipe 2415. When the core assembly 8 enters the push pipe 2415, the push rod 2416 will push the core assembly 8 into the center of the coil under the action of the cylinder 2417, thereby completing the assembly of the coil and the core;
[0048] Then, if Figure 4 As shown, the manipulator 242 includes a pneumatic clamp 2421 arranged on the frame 1, and a pair of connecting plates 2422 moving toward each other are arranged on the pneumatic clamp 2421, and the pair of connecting plates 2422 correspond to the clamping part of the core assembly 8 and the pressing plate 83 respectively. The connecting plate 2422 corresponding to the pressing plate 83 is provided with an abutment plate 2423, and the abutment plate 2423 is provided with a limiting groove 2424 matching the pressing plate 83; the connecting plate 2422 corresponding to the clamping part is provided with a correction plate 2425, and the correction plate A support plate 2426 located below the clamping portion is connected to 2425; an arc groove 2427 is provided on the correction plate 2425, and the arc groove 2427 is clamped with the clamping portion, and one side of the correction plate 2425 abuts against the end surface of the connecting tube 81, so as to make the core assembly 8 abut against the abutting plate 2423; and a limiting plate 2428 is also provided between the pair of connecting plates 2422, and one end of the limiting plate 2428 abuts against the peripheral side of the connecting tube 81, so as to limit the coil between the abutting plate 2423 and the limiting plate 2428;
[0049] The manipulator 242 will clamp the core assembly 8 with the coil, and at this time, the connecting plates 2422 of the pneumatic clamping claws are located at both ends of the core assembly, the abutment plate 2423 will correspond to one end of the pressing plate 83, and the correction plate 2425 will correspond to the clamping portion 84 of the pressing rod 82. Then, the correction plate 2425 will first be clamped on the clamping portion 84, and one side will abut against the connecting tube 81, and then the pressing plate 83 will be driven to move in the direction of the abutment plate 2423 until the pressing plate 83 is clamped in the limiting groove 2424; at the same time, the limiting plate 2428 on the manipulator will abut against the top of the connecting tube and be located at one end of the coil, thereby limiting the coil between the limiting plate 2428 and the pressing plate 83, and finally realizing the clamping of the coil and the core assembly 8, and ensuring that the relative position of the coil and the core assembly will not change;
[0050] Afterwards, combined Fig. 9 It can be seen that the third clamp seat 37 on the mounting seat will slide horizontally away from the coil when the guide rod 38 is pressed, and then the robot will clamp the coil and place it in the coil assembly groove 34. At this time, the two ends of the core assembly 8 will be clamped on the magnetic bracket 7 to fix the core assembly 8, and the third clamp seat 27 will clamp the coil, thereby ensuring that the relative position of the coil and the core assembly 8 will not change.
[0051] Then the mounting base 3 will be sent to the coil rotation station 25, as shown in FIG. Fig.10 As shown, the coil rotation station 25 is provided with a driving member 251 which is lifted up and down above the mounting seat, and a flip rod 252 which can slide horizontally left and right is connected to the driving member 251, and a conical head 253 facing the coil and corresponding to the rear end of the coil is provided on the flip rod 252. When the rear ends of the coil approach each other, the conical head 253 will drive the coil to rotate, and under the action of the driving member 251, the conical head 253 will move upward, so that the coil can rotate more, and a gap can be easily formed between the welding point of the coil and the static contact, which is convenient for the placement of the welding piece; at the same time, the extrusion member 254 elastically arranged on the driving member 251 will abut against the middle part of the coil, thereby preventing the coil from being driven upward by the conical head 253 and leaving the mounting seat.
[0052] Afterwards, the mounting seat will rotate to the welding station 26, such as Fig.11 As shown, the welding station 26 is provided with a welding sheet mechanism 262 and welding heads 263 located on both sides of the coil and the static contact. First, the welding sheet mechanism 262 will send the welding sheet to the welding position between the coil and the static contact through a pair of conveying rollers; then, the pressing piece 261 obliquely arranged above the mounting seat by the cylinder will push the welding part of the coil to rotate until the welding part of the coil fits with the static contact, and then a pair of welding heads will squeeze the static contact and the coil to achieve welding; finally, it will be sent to the material picking station to wait for being sent to the dividing plate 4 by the transfer station; the transfer station includes a conveyor belt located between the material picking station 27 and the feeding station 45, and a seat for placing the static contact of the coil is provided on the conveyor belt, and manipulators for clamping the coil on the seat are provided at both ends of the conveyor belt, so as to realize the clamping of the coil;

[0056] like Figure 12-13 As shown, the connection seat 5 includes a placement slot for placing the wiring terminal and a placement slot for placing the wiring board; first, the wiring board unloading station 41 allows the wiring board to be sent to the mechanical clamp under the action of the vibration plate and the feeding track, and then the mechanical clamp will clamp the wiring board 11 and place it on the connection seat 5, and then at the wiring terminal unloading station, the wiring terminal connected with the bolt will also be placed on the connection seat 5 under the action of the mechanical clamp, so as to realize the assembly of the wiring terminal and the wiring board 11, wherein a limit rod is set on the connection seat 5 when sliding, and when the mechanical clamp inserts the wiring terminal into the wiring board, the limit rod will rise to fix the wiring terminal in a limited position; then after being sent to the connection station 43, the motor on the connection station 43 will drive the screwdriver to rotate, thereby rotating the bolt on the wiring terminal inward to connect it with the wiring board;
[0057] Then the dividing plate continues to rotate, and a mechanical clamp located above the connecting seat 5 is provided on the transfer station 44. The mechanical clamp will clamp the terminal 12 connected to the terminal block 11 and place it in the terminal fixing groove 66 of the fixing seat 61; then after the fixing seat 61 reaches the discharge station 46, the discharge station 46 will place the magnetic bracket with the coil sent by the transfer mechanism 48 in the magnetic bracket clamping groove 62.

[0058] Afterwards, the finished seat 6 will be sent to the locking station 46, as shown in FIG. Fig.14 As shown, during the installation process, since the front end of the pressing rod is normally located at the welding position of the coil and the terminal board, it will hinder the welding of the two. Therefore, it is necessary to lock the station 46 so that the front end of the pressing rod 82 is inserted into the connecting tube 81, thereby avoiding the obstruction of welding.
[0059] The locking station 46 includes a locking rod 461 slidably arranged on the fixed seat 61 and corresponding to the pressing plate 83, and the locking rod 461 is provided with a locking portion 462 at one end thereof opposite to the pressing plate 83, and the locking portion 462 can be clamped between the pressing plate 83 and the connecting tube 81, and is used to limit the sliding reset of the pressing rod 82 in the direction of the connecting tube 81; it also includes a driving plate 463 slidably arranged on the frame 1, and the driving plate 463 is provided with a triangular conical block 464 at one end thereof facing the locking rod 461, and the locking rod 461 is provided with a pin shaft 465 matching the conical block 464; when the driving plate 463 moves in the direction of the pin shaft 465, the locking rod 461 moves in the direction away from the core assembly 8; it also includes a telescopic push rod 466 arranged on the frame 1 in front of the fixed seat 61, and the telescopic push rod 466 moves in the direction of the core assembly 8, and is used to push the pressing plate 83 in the direction away from the connecting tube 81;

The telescopic push rod 466 corresponds to the clamping portion 84 of the pressing rod 82, and can press the pressing rod 82 into the connecting tube 81, and make the pressing plate away from the connecting tube 81. At this time, the driving plate 463 located at the rear of the finished product seat 6 will move toward the pin shaft 465 connected with the locking rod 461. Under the action of the conical block 464, the pin shaft will drive the locking rod 461 to slide in the direction away from the core assembly 8. Then, after the pressing plate 83 is pushed by the telescopic push rod 466, the locking rod 461 is reset and abuts against one side of the pressing plate 83, so that the pressing plate 83 cannot be reset, thereby achieving the locking of the pressing rod 82.
[0061] Then, the finished product seat 6 will rotate to the pressure welding station 47. The pressure welding station 47 is provided with a push rod located behind the finished product seat 6. The push rod will push the guide rod connected to the connecting block, thereby driving the support block 65 to move away from the coil, and finally a gap will be generated between the terminal board 11 and the coil, and then the welding sheet will be sent into the gap between the two, and finally welding will be achieved through two welding heads.
[0062] After welding is completed, visual inspection can be used to check whether the product has any defects, and then it is sent to the material removal station and sent to the collection box by a mechanical gripper.
[0063] Through the above-mentioned processes, the overall assembly and welding of the magnetic release assembly is finally completed, the manual processing links are reduced, and the production quality and efficiency are improved.
[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
