[0006] The spring feeding assembly is arranged to send the spring in the vibrating tray into the inner sleeve of the roller in sequence; the spring pusher is arranged to limit the spring, so that only one spring falls into the receiving hole of the moving strip from the feeding pipe each time; the spring adjacent to the lowermost spring is separated by the spring pusher when the lowermost spring falls into the receiving hole, so that only one spring falls into the inner sleeve of the roller on the conveying belt each time.

[0007] As preferred, the iron core assembling device is arranged on the side of the spring feeding assembly, the iron core feeding assembly is arranged on the side of the conveying belt, and the iron core distributing assembly is arranged directly above the conveying belt; the iron core feeding assembly comprises a tray rack, an iron core hopper, a swing cylinder, a connecting block, a fan-shaped feeding piece and a swing arm, the tray rack is mounted on a rack, the tray rack is provided with the iron core hopper and the connecting block arranged side by side, a metal pipeline connected between the iron core hopper and the connecting block is arranged, and the metal pipeline is arranged at an inclined angle with the horizontal plane; the tray rack is provided with the swing cylinder hinged thereto, one end of the swing arm is hinged to the connecting block, and the other end of the swing arm is fixedly connected to the fan-shaped feeding piece; the piston shaft of the swing cylinder is hinged to the swing arm through a first pin shaft; when the piston shaft of the swing cylinder extends or retracts, the swing arm pushes the fan-shaped feeding piece to rotate relative to the iron core hopper; the end surface of the fan-shaped feeding piece facing the iron core hopper is provided with an annular groove for placing the assembled product; the iron core hopper is provided with an inclined part for stacking the assembled product; a filling part for preventing the assembled product from being stuck in the fan-shaped feeding piece is arranged between the iron core hopper and the fan-shaped feeding piece, and the filling part is arranged on the end surface of the iron core hopper facing the connecting block; the connecting block is provided with a first through hole, and the iron core distributing assembly comprises a receiving block, and a resin pipeline connected between the receiving block and the connecting block.

[0008] When the iron core feeding assembly is working, the assembly product will enter the metal pipe under the pushing of the swing cylinder, and then enter the iron core distributing assembly along the metal pipe. The assembly product includes the iron core and the rubber core, and the falling direction of the assembly product along the first through hole into the iron core distributing assembly is randomly disturbed. When the swing cylinder pushes the swing arm, the swing arm rotates relative to the connecting block. When the swing arm rotates, the fan-shaped feeding part is driven to rotate, and then the assembly product will roll along the inclined part into the annular groove, and then enter the metal pipe along the annular groove, and then enter the resin pipe along the first through hole in the connecting block.

[0009] As preferred, the iron core distributing assembly further comprises a turnover assembly, a support base, a fourth cylinder, a fifth cylinder, a first push block and a second push block; the support base is installed on the rack, the receiving block is installed on the support base, and the turnover assembly is arranged on the support base; the turnover assembly comprises a gear, a rack, a sixth cylinder and a rotating disc, the piston shaft of the sixth cylinder is connected with the rack, the rotating disc is installed on the receiving block through a bearing, an extension rod is arranged on the rotating disc, the gear is installed on the extension rod of the rotating disc and rotates synchronously with the rotating disc, the gear is meshed with the rack, a columnar through hole for the assembly product to pass through is arranged in the middle of the rotating disc, and the assembly product comprises an iron core and a rubber core; the fourth cylinder and the first push block are arranged above the rotating disc, the piston shaft of the fourth cylinder is connected with the first push block, and a second through hole for placing the assembly product is arranged on the first push block; a third through hole for receiving the assembly product is arranged at the position of the receiving block directly above the rotating disc, the second push block is arranged directly below the rotating disc, the second push block is connected with the piston shaft of the fifth cylinder, and a fourth through hole for receiving the assembly product is arranged on the second push block; a Hall sensor for detecting the positional relationship between the iron core and the rubber core is further arranged on the receiving block, and a detection through hole opposite to the Hall sensor is arranged on the side surface of the rotating disc; when the Hall sensor detects that the iron core is directly above the rubber core, the sixth cylinder pushes the rack to rotate the rotating disc by 180 degrees.

[0010] Since the falling direction of the assembly product into the receiving block is randomly disturbed, the iron core distributing assembly is required to uniformly arrange the direction of the assembly product, so that the falling direction of the assembly product into the drum sleeve is unique, and the rubber core needs to be directly above the iron core in the actual assembly process.

[0011] When the rubber core falls from above the iron core, the iron core of the combined product is in the columnar through hole, and the rubber core is in the opening position of the columnar through hole, so that the Hall sensor can only detect the signal of the iron core, and the turnover assembly will not drive the rotating disc to rotate; after the detection process is completed, the fifth cylinder controls the movement of the second push block, so that the fourth through hole on the second push block is opposite to the columnar through hole, so that the combined product falls into the inner sleeve of the roller along the fourth through hole. When the iron core falls from above the rubber core, the signal of the metal material detected by the Hall sensor during the detection process will change, because the Hall sensor cannot generate a signal when it encounters the rubber core when the rubber core is downward, and a signal will only be generated when the iron core is opposite to the Hall sensor. Therefore, when the combined product with the rubber core below the iron core is in the columnar through hole, the signal generation time of the Hall sensor will be different, and the turnover assembly will receive the signal and drive the rotating disc to rotate by 180 degrees, and then the fifth cylinder controls the movement of the second push block, so that the fourth through hole on the second push block is opposite to the columnar through hole, and then the combined product falls into the inner sleeve of the roller along the fourth through hole. Therefore, the iron core distribution assembly can unify the orientation of the combined product.

[0012] As preferred, the detection device and the defective product removing assembly are further arranged between the iron core assembling device and the sealing ring assembling device, the detection device comprises a first detection station for detecting the number of spring installations in the inner sleeve of the roller and a second detection station for detecting the orientation of the combined product, the first detection station comprises a fixed plate, a seventh cylinder, a detection mounting seat, a first proximity switch, a second proximity switch and a detection shaft; the fixed plate is arranged on the side of the installation support, the seventh cylinder is arranged on the fixed plate, and the detection mounting seat is mounted on the piston shaft of the seventh cylinder; a waist-shaped hole is arranged on the side wall of the detection mounting seat, and the first proximity switch is arranged on the waist-shaped hole; a second proximity switch is arranged on the other side wall of the detection mounting seat; a shaft sleeve is arranged on the bottom plate of the detection mounting seat, and the detection shaft is arranged in the shaft sleeve and can move up and down relative to the shaft sleeve; the second detection station is arranged adjacent to the first detection station and close to the defective product removing assembly, and comprises an eighth cylinder, a placing rack, a metal detection switch and a placing plate; the placing rack is arranged on the side of the installation support, the eighth cylinder is arranged on the placing rack, a placing plate is arranged on the piston shaft of the eighth cylinder, and the metal detection switch is arranged on the placing plate.

[0013] The first detection station is used for detecting whether the number of springs in the inner sleeve of the roller is accurate. When there is only one spring in the inner sleeve of the roller, the seventh cylinder pushes the detection mounting seat to move downward, and the detection shaft is synchronized to move close to the spring in the inner sleeve of the roller. When the spring contacts the detection shaft, the detection shaft moves upward and is close to the first proximity switch. At this time, the signal emitted by the first proximity switch is blocked by the detection shaft, and the first proximity switch feeds back the signal change to the control circuit. The second proximity switch is not blocked by the detection shaft at this time and does not generate an electrical signal. In this way, the product detection result is a qualified product. When multiple springs are placed in the inner sleeve of the roller, the detection shaft moves upward a greater distance after contacting the spring. At this time, the electrical signals emitted by the first proximity switch and the second proximity switch are simultaneously blocked by the detection shaft and feed back the signal change to the control circuit. In this way, the product detection result is an unqualified product.

[0014] The second detection station is used for detecting whether the combined product coming out of the iron core material distribution assembly is accurate. When detecting, the eighth cylinder works to control the metal detection switch to move downward and close to the combined product. When the iron core in the combined product is directly above the rubber core, the metal detection switch feeds back the detected signal to the control circuit. At this time, the detection result is an unqualified product. When the rubber core of the combined product is directly above the iron core, the metal detection switch cannot detect the signal. At this time, the detection result is a qualified product.

[0051] The specific operation process of the embodiment is as follows: first, the inner sleeve of the roller is transferred from the conveying pipeline 101 of the first level feeding assembly 10 to the turning assembly 11, the inner sleeve of the roller is placed on the conveying belt 3 after being turned by 180 degrees by the turning assembly 11, and then a spring is installed into the inner sleeve of the roller in sequence by the spring feeding assembly 4; the working principle of the spring feeding assembly 4 is as follows: the spring first falls along the feeding pipe 41 into the guide through hole 48 of the spring stopper 42, at this time, the receiving hole 49 on the moving strip 44 is opposite to the guide through hole 48, so that the spring automatically falls into the receiving hole 49 under the action of gravity; then the second cylinder 47 works to push the spring top block 43 into the guide through hole 48 to stop the spring adjacent to the lowermost spring, so that all the springs in the feeding pipe 41 cannot continue to fall; then the first cylinder 46 works to push the moving strip 44 so that the spring in the receiving hole 49 is directly below the spring ejector pin 411, and then the third cylinder 410 works to control the spring ejector pin 411 to move downward, so that the spring is placed into the inner sleeve of the roller. After that, the receiving hole 49 on the moving strip 44 returns to the position directly below the guide through hole 48, and the above steps are repeated, so that the spring can be continuously installed into the inner sleeve of the roller.

[0052] After the spring is installed, the assembly product is installed through the iron core distributing assembly 52 into the drum inner sleeve and above the spring. The assembly product is first moved by the spring feeding assembly 4 into the receiving block 522 of the iron core distributing assembly 52; the swing cylinder 502 drives the swing arm 506 to rotate back and forth, and the swing arm 506 rotates while the fan-shaped feeding piece 503 rotates relative to the iron core hopper 501, so that the assembly product will roll along the inclined part 510 into the annular groove 509, and then along the annular groove 509 into the connecting block 504, and then along the connecting block 504 into the resin pipeline 532. Then the iron core distributing assembly 52 starts to work, and the orientation of the assembly product is unified by the turnover assembly 521. When the rubber core is above the iron core and falls down, the iron core of the assembly product will be in the cylindrical through hole 556, and the rubber core will be in the opening position in the cylindrical through hole 556, so that the Hall sensor 531 can only detect the signal of the iron core, and then the turnover assembly 521 will not drive the rotating disc 554 to rotate; during the detection of the assembly product, the second push block 527 will abut against the bottom of the cylindrical through hole 556, so that the assembly product in the receiving block 522 will not move downward; after the detection process is completed, the fifth cylinder 525 controls the movement of the second push block 527, so that the fourth through hole 530 on the second push block 527 is opposite to the cylindrical through hole 556, so that the assembly product will fall down along the fourth through hole 530 into the drum inner sleeve. When the iron core is above the rubber core and falls down, the signal of the metal material detected by the Hall sensor 531 during the detection process will change, because the Hall sensor 531 cannot generate a signal when it encounters the rubber core when the rubber core is downward, and a signal will be generated only when the iron core is opposite to the Hall sensor. Therefore, when the assembly product with the rubber core below the iron core is in the cylindrical through hole 556, the signal generated by the Hall sensor 531 will be different in time, and then the turnover assembly 521 will receive the signal and drive the rotating disc 554 to rotate 180 degrees, and then the fifth cylinder 525 controls the movement of the second push block 527, so that the fourth through hole 530 on the second push block 527 is opposite to the cylindrical through hole 556, and then the assembly product will fall down along the fourth through hole 530 into the drum inner sleeve. When the turnover assembly 521 works, the sixth cylinder 533 pushes the rack 552 to move, and the rack 552 drives the gear 551 to mesh and rotate, and the gear 551 rotates while driving the rotating disc 554 to rotate. Therefore, the orientation of the assembly product can be unified through the iron core distributing assembly 52.

[0053] Then the number of springs in the inner sleeve assembly is detected by the first detection station 81 in the detection assembly 52, and then the installation direction of the assembled product is detected by the second detection station 82. The working principle of the first detection station 81 is as follows: when there is only one spring in the inner sleeve, the seventh cylinder 812 pushes the detection seat to move down, and the detection shaft 816 is synchronized to move close to the spring in the inner sleeve. When the spring contacts the detection shaft 816, the detection shaft 816 moves up and approaches the first proximity switch 814. At this time, the electrical signal emitted by the first proximity switch 814 is blocked by the detection shaft 816, so that the electrical signal generated by the first proximity switch 814 changes and is fed back to the control circuit. The second proximity switch 815 is not blocked by the detection shaft 816 at this time and the electrical signal does not change, so that the product detection result is a qualified product; when multiple springs are placed in the inner sleeve, the detection shaft 816 moves upward a greater distance after contacting the spring. At this time, the electrical signals generated by the first proximity switch 814 and the second proximity switch 815 are blocked by the detection shaft 816 at the same time, so that the first proximity switch 814 and the second proximity switch 815 feed back the changed electrical signals to the control circuit, so that the product detection result is unqualified. The working principle of the second detection station 82 is as follows: the eighth cylinder 821 works to control the metal detection switch 823 to move down and approach the assembled product. When the iron core in the assembled product is directly above the rubber core, the metal detection switch 823 will feed back the detected signal to the control circuit, and at this time the detection result is unqualified; when the rubber core of the assembled product is directly above the iron core, the metal detection switch 823 cannot detect the signal, and at this time the detection result is qualified. After detecting the unqualified product, the unqualified product is removed by the defective product removing assembly 13.

[0054] After the product detection process is completed, the sealing ring assembly begins. First, the sealing ring is placed in the opening of the inner sleeve by the sealing ring clamping assembly 91, and then the sealing ring is pressed tightly by the sealing ring pressing assembly 92. The sealing ring clamping assembly 91 moves the sealing ring in the horizontal direction by the third sliding block 904, and moves the sealing ring by the fourth sliding block 905, so as to facilitate the movement of the sealing ring in the horizontal and vertical directions.

[0055] Then the product is clamped by the blanking assembly 12 to the material frame 71 of the tray assembly 7, transported by the tray assembly 7 to the transfer assembly 6, and then transported by the transfer assembly 6 to the blanking assembly 15; the second slide rail 122 is arranged on the blanking assembly 12, a screw rod is arranged in the second slide rail 122, the screw rod is connected with the second motor 123, the first sliding platform 124 is arranged on the second slide rail 122, a threaded sleeve that is engaged with the screw rod is arranged on the first sliding platform 124, and the first sliding platform 124 moves along the second slide rail 122 while the screw rod rotates driven by the second motor 123. Similarly, the third motor 63 drives the moving platform 64 to move along the third slide rail 62 by the same principle as above, and the first motor 73 drives the placing platform 74 to move along the first slide rail 72 by the same principle as above.

[0056] The transfer assembly 6 comprises the moving platform 64 that moves along the horizontal direction and the lifting platform 66 that moves along the vertical direction, and the third clamping arm 68 is arranged on the lifting platform 66, so as to facilitate the transfer of the material frame 71 in the horizontal direction and the vertical direction. Two lifting platforms 66 are arranged on the moving platform 64, one of which is close to the feeding assembly 14, and the other is close to the blanking assembly 15, and the moving platform 64 controls the two lifting platforms 66 to move along the third slide rail 62 at the same time. In the initial state, the first empty material frame 71 is placed on the tray assembly 7, and the tray assembly 7 drives the first empty material frame 71 to be close to the blanking assembly 12; the blanking assembly 12 places the product on the first empty material frame 71, and then the tray assembly 7 transports the first material frame 71 full of products to the position directly below one of the lifting platforms 66, and then the two lifting platforms 66 move downward at the same time, one of the lifting platforms 66 clamps the second empty material frame 71, and the other clamps the first material frame 71 full of products, and then the moving platform 64 controls the two lifting platforms 66 to move synchronously, and finally the two lifting platforms 66 control the third clamping arm 68 to move downward at the same time; one of the lifting platforms 66 places the second empty material frame 71 on the tray assembly 7, and the other places the first material frame 71 full of products on the blanking assembly 15, so that the transfer assembly 6 can transfer two material frames 71 at the same time, greatly improving the product transfer efficiency.
