A connecting column 113 is provided at the central position of the first turntable 110. A lifting column 123 is provided inside the connecting column 113. A turntable lifting cylinder 121 connected to the lifting column 123 is provided inside the machine base 100. The other end of the lifting column 123 is connected to a second turntable 120. The second turntable 120 can move closer to or away from the first turntable 110 in the axial direction of the first turntable 110 under the drive of the turntable lifting cylinder 121.

[0047] A main body feeding mechanism 300, a door seal feeding mechanism 400, a torsion spring feeding mechanism 500, an assembling mechanism 600, and a blanking mechanism 700 are arranged on the machine base 100 in sequence along the rotation direction of the first turntable 110.

[0048] A plurality of fixing grooves 112 are provided on the top of the first turntable 110. The plurality of fixing grooves 112 are arranged in a circular array centered on the first turntable 110. A fixing die 200 is provided in each fixing groove 112.

[0049] The top surface of the fixed mold 200 is provided with a first clamping groove 210 and a second clamping groove 220. The first clamping groove 210 is used to fix the lobster clasp main body 130, and the second clamping groove is used to fix the lobster clasp door seal 140. Moreover, the first clamping groove 210 and the second clamping groove 220 are communicated, so that the subsequent assembling mechanism 600 can push the lobster clasp door seal 140 into the first clamping groove 210 for assembling with the lobster clasp main body 130.

[0050] As is well known, a cylinder is provided on the lobster clasp door seal 140 for fixing the lobster clasp torsion spring 150 thereon, so that after the lobster clasp main body 130, the lobster clasp door seal 140 and the lobster clasp torsion spring 150 are assembled, the door seal can elastically move under the action of the lobster clasp torsion spring 150.

[0051] A lifting block 270 is arranged at the bottom of the fixed mold 200. When the fixed mold 200 is installed on the fixed groove 112, there is a descending gap between the bottom of the lifting block 270 and the fixed groove 112. A connecting rod 280 is arranged at the bottom of the first turntable 110 and extends through the first turntable 110 into the fixed groove 112 to be connected with the lifting block 270, and a clamping groove connected with the assembling mechanism 600 is arranged at the bottom end of the connecting rod 280.

[0052] A first through groove 240, a second through groove 250 and a third through groove 260 are opened on the fixed mold 200. A first limiting member 241, a second limiting member 251 and a third limiting member 261 are arranged on the lifting block 270. The first limiting member 241 is arranged in the first through groove 240, the second limiting member 251 is arranged in the second through groove 250, and the third limiting member 261 is arranged in the third through groove 260. Under normal conditions, the tops of the first limiting member 241, the second limiting member 251 and the third limiting member 261 are all located in the second clamping groove 220, and at least the first limiting member 241 and the second limiting member 251 cooperate to form a limiting area for realizing the limiting and fixing of the lobster clasp door seal 140. During use, the connecting rod 280 drives the lifting block 270 to descend under the drive of the assembling mechanism 600. The lifting block 270 drives the first limiting member 241, the second limiting member 251 and the third limiting member 261 to descend and be received in the fixed mold 200, releasing the limit on the lobster clasp door seal 140 to ensure that the lobster clasp door seal 140 can enter the first clamping groove 210 under the drive of the assembling mechanism 600 for assembling with the lobster clasp main body 130.

[0053] Furthermore, a fourth through groove 290 is opened on the fixed mold 200, and a fourth limiting member 291 is arranged on the lifting block 270. The fourth limiting member 291 is arranged in the fourth through groove 290 and is used for supporting and limiting the lobster clasp door seal 140.

[0054] The main body feeding mechanism 300 includes a first vibrating disk 310 arranged on the machine base 100, a main body feeding component 330, a main body pressing-down component 340, and a main body receiving part 320 arranged on the main body feeding component 330. The first vibrating disk 310 is a feeding vibrating disk in the prior art. The main body receiving part 320 is a rod-shaped structure matching the shape of the lobster clasp main body 130, and is used to connect with the discharging end of the first vibrating disk 310, so that a plurality of lobster clasp main bodies 130 are stacked on the main body receiving part 320, and the bottom is arranged on the main body feeding component 330 for the main body feeding component 330 to pick up and feed materials.

[0055] The main body feeding component 330 includes a first base 336 arranged on the machine base 100 through a plurality of plates. The top of the first base 336 has a first groove for accommodating the first main body feeding plate 332 and the second main body feeding plate 333. The side part is connected with a main body feeding cylinder 331. The piston of the main body feeding cylinder 331 is connected with the first main body feeding plate 332 and the second main body feeding plate 333 through a plate-shaped or block-shaped structure. A main body clamping groove 334 is formed between the first main body feeding plate 332 and the second main body feeding plate 333, and the distance between the first main body feeding plate 332 and the second main body feeding plate 333 is adjustable, so as to adjust the size of the main body clamping groove 334 and switch the clamping state or the detachable state of the lobster clasp main body 130.

[0056] Specifically, a first guiding block 335 is arranged on the side wall of the groove. The guiding surface of the first guiding block 335 inclines from the side close to the first turntable 110 to the middle of the first groove on the side away from the first turntable 110, ensuring that the distance between the first main body feeding plate 332 and the second main body feeding plate 333 is adjusted under the telescopic action of the main body feeding cylinder 331, so as to realize the clamping and feeding of the lobster clasp main body 130 and the pressing of the lobster clasp main body 130 onto the fixed die 200 by the main body pressing-down component 340.

[0057] The main body pressing-down component 340 includes a first connecting plate 341 connected to the machine base 100 and the main body receiving part 320 through a plurality of plates. A main body pressing-down cylinder 342 is arranged on the first connecting plate 341. A main body pressing-down block 343 corresponding to the position of the first clamping groove 210 of the fixed die 200 is connected to the piston of the main body pressing-down cylinder 342. When the first main body feeding plate 332 and the second main body feeding plate 333 clamp the lobster clasp main body 130 and displace to above the first clamping groove 210, the main body pressing-down block 343 is used to press down the lobster clasp main body 130 into the first clamping groove 210 for fixation.

[0058] The door seal feeding mechanism 400 includes a second vibrating disk 410 arranged on the machine base 100, a door seal feeding component 430, a door seal receiving part 420, and a door seal pressing-down component 460. The second vibrating disk 410 is a feeding vibrating disk in the prior art. The door seal receiving part 420 is a plate-like structure with a guide groove in an inclined shape, and is used to connect with the discharging end of the second vibrating disk 410, so that a plurality of lobster buckle door seals 140 are conveyed onto the door seal feeding component 430 under the guiding action of the guide rail.

[0059] In order to avoid the continuous falling of the lobster buckle door seals 140, a door seal limiting cylinder 440 is connected to the door seal receiving part 420 through a plurality of plates. The piston of the door seal limiting cylinder 440 is connected with two door seal limiting rods 450 through two plates. One of them is inserted into the guide groove from the top of the door seal receiving part 420, and the other is inserted into the guide groove from the bottom of the door seal receiving part 420. And a spring for resetting is arranged on the piston of the door seal limiting cylinder 440.

[0060] During use, the distance between the two door seal limiting rods 450 can only accommodate one lobster buckle door seal 140. The piston of the door seal limiting cylinder 440 extends to push the door seal limiting rod 450 inserted into the guide groove from the bottom of the door seal receiving part 420 to displace, so that it disengages from the guide groove. The lobster buckle door seal 140 located between the two door seal limiting rods 450 disengages from the limit and falls to the door seal feeding component 430. The piston of the door seal limiting cylinder 440 resets and contracts, so that the door seal limiting rod 450 inserted into the guide groove from the top of the door seal receiving part 420 disengages from the guide groove, and the lobster buckle door seal 140 in the guide groove falls between the two door seal limiting rods 450, waiting for the next door seal feeding.

[0061] The door seal feeding component 430 includes a second base 435 arranged on the machine base 100 through a plurality of plates. The top of the second base 435 has a second groove for accommodating a first door seal feeding plate 432 and a second door seal feeding plate 433. The side part is connected with a door seal feeding cylinder 431. The piston of the door seal feeding cylinder 431 is connected with the first door seal feeding plate 432 and the second door seal feeding plate 433 through a plate-like or block-like structure. A door seal clamping groove 434 is formed between the first door seal feeding plate 432 and the second door seal feeding plate 433. And the distance between the first door seal feeding plate 432 and the second door seal feeding plate 433 is adjustable, so as to adjust the size of the door seal clamping groove 434 and switch the clamping state or the detachable state of the lobster buckle door seal 140.

[0062] Specifically, a second guiding block is provided on the side wall of the groove. The guiding surface of the second guiding block inclines from the side close to the first turntable 110 towards the middle of the second groove away from the first turntable 110, ensuring that the distance between the first door seal feeding plate 432 and the second door seal feeding plate 433 is adjusted under the telescopic action of the door seal feeding cylinder 431, so as to realize the clamping and feeding of the lobster buckle door seal 140 and press it onto the fixed mold 200 by the door seal pressing component 460.

[0063] The door seal pressing component 460 includes a door seal pressing cylinder 461 arranged on the second turntable 120 through a plurality of plate bodies. The piston of the door seal pressing cylinder 461 is connected with a door seal pressing block 462 corresponding to the limiting area in the second clamping groove 220 of the fixed mold 200. During actual use, when the door seal is conveyed to the position corresponding to the second clamping groove 220 of the fixed mold 200 under the clamping action of the first door seal feeding plate 432 and the second door seal feeding plate 433, the door seal pressing block 462 presses the door seal in the door seal clamping groove 434 into the limiting area for limiting and fixing under the drive of the door seal pressing cylinder 461.

[0064] The torsion spring feeding component includes a third vibrating disk 510 arranged on the machine base 100, a torsion spring receiving part 520, a torsion spring feeding component 530 and a first torsion spring bending component, and a second torsion spring bending component 550 arranged on the torsion spring feeding component 530. The third vibrating disk 510 is a feeding vibrating disk in the prior art. The torsion spring receiving part 520 is arranged obliquely, and the feeding end of the torsion spring receiving part 520 is connected with the discharging end of the third vibrating disk 510.

[0065] It can be understood that it is inevitable to set sensors on the torsion spring receiving part 520 to detect whether the torsion spring reaches the set position, so as to facilitate the material taking of the torsion spring feeding component 530 and prevent the torsion spring from falling off, which will not be elaborated here.

[0066] The torsion spring feeding component 530 includes a third base 534 connected to the machine base 100 through a plurality of plate bodies. A first torsion spring feeding cylinder 531 is arranged on the third base 534. A second torsion spring feeding cylinder 532 is connected to the piston of the first torsion spring feeding cylinder 531 through a plurality of plate bodies. A torsion spring adjusting cylinder 535 is connected to the piston of the second torsion spring feeding cylinder 532 through a plurality of plate bodies. The piston of the torsion spring adjusting cylinder 535 is connected with a torsion spring clamping part 533 through a plurality of plate bodies. During actual use, the piston of the first torsion spring feeding cylinder 531 stretches and drives the torsion spring clamping part 533 to approach or move away from the fixed mold 200 in the radial direction of the first turntable 110, and the piston of the second torsion spring feeding cylinder 532 drives the torsion spring clamping part 533 to approach or move away from the fixed mold 200 in the axial direction of the first turntable 110.

[0067] Moreover, the torsion spring clamping member 533 adopts a structure with two clamping arms. The piston expansion and contraction of the torsion spring adjusting cylinder 535 can drive the torsion spring clamping member 533 to move on the plate body. By arranging an inclined groove body on the plate body, the distance between the two clamping arms can be adjusted, so that after the two clamping arms are inserted into the lobster clasp torsion spring 150, they can move away from each other to realize the state switching between the tight clamping of the lobster clasp torsion spring 150 and the torsion spring clamping member 533 and the separation from each other.

[0068] The first torsion spring bending assembly 540 includes a fourth base connected to the machine base 100 through a plate body. A first driving cylinder 543 is provided on the fourth base. The first driving cylinder 543 is connected with a first torsion spring bending cylinder 541 through a sliding rod. A bending pull block 544 is connected to the piston of the first torsion spring bending cylinder 541. A first torsion spring bending rod 542 is provided on the bending pull block 544.
