[0048] See also Figures 1-10 As shown, the present invention provides an assembly process of a special-shaped gasket and a bolt, comprising the following steps:

[0049] S1. Pour a number of special-shaped gaskets into the gasket storage hopper 100;

[0050] S2, then simultaneously start the film conveying motor 230 and the transmission motor 320 to drive the conveyor belt 210 and the transmission belt 310 to circulate, and then insert the hexagonal end of the bolt into the driving hole 311 of the transmission belt 310;

[0051] S3, the special-shaped gasket is hung on the hanging plate column 220 and transported to the top of the transmission belt 310 by the conveyor belt 210, and falls onto the top of the bolt driven by the transmission belt 310;

[0052] S4. As the transmission belt 310 moves, the bolt with the special-shaped gasket passes under the pressing plate assembly 400, and the special-shaped gasket is pressed to the hexagonal end of the bolt, and the assembly is completed;

[0053] S5. When the bolt is pushed by the transmission belt 310 to the discharge port 331 at the right end of the bolt support ring 330, the bolt falls into the inner side of the transmission belt 310 until the pushing hole 311 at the top moves under the bolt, and then the bolt falls into the collection box 340 to be collected;

[0054] The assembly structure includes a film storage hopper 100 , a film transport mechanism 200 with its left end located inside the film storage hopper 100 , a film loading mechanism 300 located directly below the film transport mechanism 200 , and a tablet pressing group 400 suspended above the right end of the film loading mechanism 300 .

[0055] Specifically, the film transport mechanism 200 includes a trapezoidal conveyor belt 210, a plurality of film hanging posts 220 embedded in the conveyor belt 210, and a film transport motor 230 mounted on the bottom front side of the film storage hopper 100. The left side of the conveyor belt 210 is located inside the film storage hopper 100, and an I-shaped pulley 241 coaxially connected to the film transport motor 230 is mounted at the lower left corner of the conveyor belt 210.

[0056] A fixed belt frame 240 is provided at the upper right corner of the conveyor belt 210. The fixed belt frame 240 has a triangular structure and its triangular parts are rotatably connected to I-shaped wheels 241 to stabilize the structure of the conveyor belt 210. A number of hanging column 220 is used to automatically hang the special-shaped gaskets from the storage bucket 100 and transport them out.

[0057] Furthermore, the bottom of the film storage hopper 100 is connected and welded with a square tube seat 101, and a discharge port 102 is opened on the radial right side of the top of the film storage hopper 100. The right side of the square tube seat 101 is open, and the upper left side of the conveyor belt 210 passes through the discharge port 102. The film transport motor 230 is located on the front side of the square tube seat 101, and the I-wheel 241 on its output shaft is embedded between the inner walls of the square tube seat 101.

[0058] Specifically, a plurality of circular holes are formed at equal intervals on the center line of the surface of the conveyor belt 210, and a threaded sleeve 211 is inserted into each circular hole. The half of the hanging column 220 facing the inner side of the conveyor belt 210 is provided with threads. The hanging column 220 is threadedly connected to the threaded sleeve 211, thereby adjusting the length of the hanging column 220 protruding from the conveyor belt 210 to accommodate special-shaped gaskets of different axial heights.

[0059] The center distance between two adjacent threaded sleeves 211 is equal to the center distance between two adjacent shifting holes 311. The rotation speeds of the film conveying motor 230 and the transmission motor 320 are the same, so that when the shifting hole 311 drives the bolt to move below the right end of the conveyor belt 210, it can receive the special-shaped gasket that slides down from the outside of the hanging column 220.

[0060] It is worth noting that a sealing assembly 250 is provided on the inner wall of the film storage hopper 100 and on both sides of the conveyor belt 210 to seal the space between the left side of the conveyor belt 210 and the film storage hopper 100, thereby preventing irregularly shaped gaskets from being stored therein and allowing the irregularly shaped gaskets to be picked up and transported out one by one by the hanging column 220.

[0061] The sealing assembly 250 includes a pair of sealing plates 251, a sealing box 253 welded to the inner side of the left corner of the bottom end of the sealing plate 251, and a sealing block 254 inserted into the sealing box 253. The sealing box 253 is welded to the inner side of the top end of the square tube seat 101 to seal the special-shaped gaskets, so that they are accumulated on the left bottom side of the conveyor belt 210 so that they can be hung by the hanging column 220.

[0062] A compression spring 255 is embedded between the sealing block 254 and the sealing box 253. The distance between the pair of sealing boxes 253 is greater than the outer diameter of the hanging column 220, so that the hanging column 220 passes between the pair of sealing boxes 253 and squeezes the pair of sealing blocks 254 open. Then, the pair of sealing blocks 254 automatically closes the gap between the pair of sealing boxes 253 under the action of the rebound force of the compression spring 255.

[0063] Furthermore, a column adjustment group 260 for adjusting the extension length of the hanging column 220 is provided inside the sealing group 250. The column adjustment group 260 includes a pair of dial plates 261 and a small motor 262 coaxially connected to the dial plates 261.

[0064] The output shaft end of the small motor 262 is coaxially connected to a screw rod, and the screw rod is threadedly connected to the threaded hole provided in the middle of the selector plate 261. Guide plates 252 are welded at upper and lower intervals on the inner side of the sealing plate 251. The selector plate 261 has a U-shaped structure and is engaged with a pair of guide plates 252 on the same side. When the small motors 262 located at the front and rear are started to drive the screw rod to rotate, due to the restriction of the guide plate 252, the selector plate 261 will extend or contract along the axial direction of the screw rod, thereby selecting to contact the radial front or rear side of the hanging piece column 220. As the conveyor belt 210 drives the hanging piece column 220 to roll on the side of the selector plate 261, the extension length is adjusted to match the special-shaped gaskets of different heights.

[0065] The distance between the pair of shift plates 261 is equal to the outer diameter of the inner end of the hanging column 220. The side surface of the shift plates 261 is frosted to increase the friction of the hanging column 220 for smooth rotation.

[0066] In addition, the film loading mechanism 300 includes a transmission belt 310, a transmission motor 320, and a bolt support ring 330 disposed inside the transmission belt 310. The output shaft of the transmission motor 320 is coaxially connected to a double-piece wheel 321 that is sleeved on the transmission belt 310. That is, the two wheels are spaced apart in the middle to allow the bolts to fall into the inner side of the transmission belt 310.

[0067] The size of the bolt support ring 330 is reduced in proportion to the size of the transmission belt 310. The bolt support ring 330 is used to press against the hexagonal end of the bolt to prevent the bolt from falling off at the left end and the middle section of the transmission belt 310.

[0068] A number of shifting holes 311 are provided at equal intervals on the center line of the surface of the transmission belt 310. The shifting holes 311 are strip-shaped hole structures with a small left end and a large right end. The large hole diameter is larger than the outer diameter of the special-shaped gasket and the hexagonal end of the bolt, and the small hole diameter is equal to the outer diameter of the bolt. In this way, the bolt is clamped at the left end of the transmission belt 310 and the belt is moved to the right end.

[0069] Furthermore, a discharge port 331 is vertically opened on the arc surface at the right end of the bolt support ring 330, and a guide sleeve 332 is sleeved between the upper and lower discharge ports 331 of the bolt support ring 330 to guide the bolt to fall vertically downward; a number of reinforcing ribs 333 are welded at equal intervals inside the right section of the bolt support ring 330 to stabilize the bolt support ring 330 and support the pressure plate group 400 to apply pressure to the special-shaped gasket; the side plates at both ends of the bolt support ring 330 are welded to the support frames at both ends of the transmission belt 310.

[0070] Specifically, the pressing group 400 includes several double pressing wheels 410 set at different heights and a support bracket 420 connected to the double pressing wheels 410 by pins. The several double pressing wheels 410 are gradually lowered from left to right. This structure is used to gradually roll the special-shaped gasket from the upper end of the bolt to its lower end to avoid the special-shaped gasket from being dislocated and stuck.

[0071] The left end of the support bracket 420 is welded to the bottom end of the fixed belt frame 240, and the right end of the support bracket 420 is welded to the right end bracket of the transmission belt 310, so that the multiple double pressure wheels 410 are stably suspended.

[0072] In addition, a bolt delivery group 500 is provided at the left end of the transmission belt 310. The bolt delivery group 500 includes a bolt delivery belt 510, a reduction motor 520 and a pair of guide rollers 530. A pair of bolt guide plates 540 are provided above the top surface of the bolt delivery belt 510. The right end of the bolt guide plate 540 is welded to the inner side of the bottom of the square tube seat 101 to guide the bolts to be delivered axially.

[0073] Furthermore, the reduction motor 520 is coaxially connected to the round roller sleeved on the left end of the bolt delivery belt 510, and a pair of guide rollers 530 are embedded in the side wall of the square tube seat 101 and sleeved on the right end of the bolt delivery belt 510, and the pair of guide rollers 530 are symmetrically arranged up and down, so as to tighten the right end of the bolt delivery belt 510 to form a straight surface, which is conducive to docking with the left end of the transmission belt 310 and smoothly transitioning the bolts; the left end of the bolt guide plate 540 is bent and provided with an outward-inclined flaring plate 550. The staff only needs to place the hexagonal end of the bolt facing the transmission belt 310 between the flaring plates 550, and it will be transported to the left end of the transmission belt 310 by the bolt delivery belt 510 until its hexagonal end is stuck in the large-diameter hole of the dial hole 311 and is stuck and taken away by its small-diameter hole.

[0074] It should be noted that the above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
