[0002] The main functions of the lid include shielding dust and pollutants, sealing, anti-theft opening and safety protection; the lid can cover the top of the container or open object to prevent dust and pollutants from entering and keep the interior clean; in food and beverage packaging, the bottle cap has the performance of keeping the contents airtight to prevent the contents from being contaminated or deteriorated, and at the same time has the functions of anti-theft opening and safety protection.

[0003] In the traditional cap assembly process, the cap needs to be transported to the grabbing position by precise feeding equipment, and then the cap is grabbed and transferred by a robot for spinning installation.

[0066] The principle and advantages of the lid assembly machine's lid precision assembly press-in mechanism:

[0067] First, in the receiving state, the pneumatic push rod 271 pushes the sliding shaft A27 to slide along the limiting hole 16, so that the sliding shaft A27 drives the bottom plate 26 to slide between the bottom frame 24 and the V-shaped plate 22. At the same time, as the angle of the limiting hole 16 changes, the sliding shaft A27 drives the bottom frame 24 to rotate through the bottom rotating member 25, so as to adjust the opening of the receiving component 2 to align with the blanking plate 200, and then each cover body 100 is individually unloaded through the blanking plate 200, and the output cover body 100 falls into the interior of the receiving component 2 in an inclined downward direction. At this time, the V-shaped plate 22 located inside the receiving component 2 corrects and positions the cover body 100; at this time, the connecting column 210 located at the top of the receiving component 2 is on the magnet 13 Under the adsorption effect, the cover sleeve 29 is driven away from the bottom plate 26 to prevent the cover sleeve 29 from hindering the cover body 100 from entering the inner side of the V-shaped plate 22; it is worth mentioning that in the process of receiving materials, the vertical rod 47 in the clamping assembly 4 is squeezed by the pressing plate 15 and is in a downward sliding state, so that the vertical rod 47 squeezes the arc block 46 to rotate through the ball A48, and then the arc block 46 drives the clamping rod 43 on the outside of the sleeve 42 to be located at the opening of the receiving assembly 2. At this time, the torsion spring 45 forms a torsion force on the sleeve 42 to prevent the clamping rod 43 from being in a clamped state and hindering the cover body 100 from entering the inner side of the V-shaped plate 22; and the cover body 100 is positioned by the positioning column 7 on the outside of the V-shaped plate 22 to prevent friction with the V-shaped plate 22 during subsequent downward pressure.

[0068] After receiving the materials, the bottom frame 24 is driven to rotate downward to a horizontal state by the pneumatic push rod 271, and the bottom plate 26 is simultaneously driven to slide to one side, so that when the receiving component 2 is in a horizontal state, the bottom plate 26 is in an open state relative to the bottom of the receiving component 2; and when the receiving component 2 rotates downward to drive the connecting column 210 to disengage from the magnet 13, the cover sleeve 29 automatically falls on the top of the cover body 100. At this time, the cover body 100 can be vertically positioned by the matching groove 291 at the bottom of the cover sleeve 29 and the cover body 100. Since the volume of the cover body 100 is relatively large, the corresponding outer convex structure is relatively obvious. When the cover sleeve 29 falls, it drives the outer stopper 212 to be located at the cover body 10 0, and the stopper 212 is located between two adjacent protruding structures on the outside of the cover body 100. In order to make the stopper 212 better cooperate with the protruding structure, the stopper 212 is selected to have a plate or rod shape with a V-shaped bottom; and the receiving component 2 drives the vertical rod 47 away from the pressure plate 15, releases the squeezing of the vertical rod 47, and releases the squeezing of the arc block 46 by the vertical rod 47. At this time, the shaft sleeve 42 rotates automatically under the torsion force applied by the torsion spring 45, and drives the outer clamping rod 43 to automatically rotate from the opening of the receiving component 2 to the inside, so as to clamp the cover body 100, improve the stability of the cover body 100 after positioning, and prevent the cover body 100 from falling off after the bottom plate 26 is opened.

[0069] It is worth mentioning that the above-mentioned material connection method has the following advantages:

[0070] Advantage 1: The cover body 100 is received by the tilted receiving component 2, and the receiving component 2 limits the cover body 100 through the V-shaped plate 22, so that when the receiving component 2 drives the cover body 100 to rotate to a horizontal state, the cover body 100 is automatically positioned horizontally. At this time, the cover body 100 is coaxially aligned with the container below to ensure the accuracy of subsequent assembly.

[0071] Advantage 2: During the material connection process, the bottom plate 26 at the bottom of the V-shaped plate 22 is in a closed state to ensure that the cover body 100 can smoothly enter the inner side of the V-shaped plate 22. When the V-shaped plate 22 and the cover body 100 are rotated to a horizontal state, the bottom plate 26 automatically slides to one side during the rotation process to open the bottom of the V-shaped plate 22 to facilitate subsequent press-in assembly work.

[0072] Advantage three, when adjusting the material connection state, the receiving component 2 in an inclined state drives the connecting column 210 to approach the magnet 13, so that the magnet 13 adsorbs the connecting column 210, and the cover sleeve 29 is away from the bottom plate 26 to prevent the entry of the cover body 100 from being affected. When the material is connected and adjusted to a horizontal state, the receiving component 2 drives the connecting column 210 and the magnet 13 to separate from each other. At this time, the connecting column 210 drives the cover sleeve 29 to automatically fall on the top of the cover body 100 to achieve automatic alignment, so that the cover body 100 is horizontally and vertically positioned by the V-shaped plate 22 and the cover sleeve 29 to ensure the accuracy of the press-in assembly.

[0073] Advantage four: In order to ensure the matching accuracy between the cover sleeve 29 and the cover body 100, and to enable the connecting column 210 to drive the cover sleeve 29 to move under the adsorption action of the magnet 13, a ball bearing is provided between the sliding shaft B28 and the top plate 21 for sliding assembly, which can reduce the resistance of the sliding shaft B28 in axial and circumferential movement, thereby achieving precise matching between the cover sleeve 29 and the cover body 100.

[0074] Advantage five, by setting the clamping rod 43, it can be automatically located at the opening of the receiving component 2 when receiving the material, so as to prevent the feeding of the cover body 100 from being affected. When the material is received and adjusted to a horizontal state, the clamping rod 43 is automatically clamped on the inner side of the V-shaped plate 22 by the torsion force to ensure the stability of the cover body 100 after the horizontal positioning.

[0075] When the spinning component 3 in the lid precision assembly press-in mechanism of the lid assembly machine of the present application is pressed into the lid body 100, the lifting plate 32 is driven downward by the lifting drive mechanism of the lid assembly machine, and at the same time, the motor 33 on the top of the lifting plate 32 drives the spinning head 31 to rotate, so that the spinning head 31 gradually approaches the connecting column 210. When the V-shaped block 312 on the inner side of the spinning head 31 cooperates with the V-shaped groove 211 on the outer side of the connecting column 210, the spinning head 31 drives the connecting column 210 to rotate under the drive of the motor 33, so that the connecting column 210 is moved downward. The connecting column 210 drives the cover body 100 to rotate through the cover sleeve 29. When the stopper 212 on the outside of the cover sleeve 29 does not contact the protruding structure on the outside of the cover body 100 during circumferential rotation, relative sliding may occur between the cover sleeve 29 and the cover body 100. Since the cover body 100 is always located on the inner side of the cover sleeve 29, the positioning accuracy of the cover body 100 is not affected. When the stopper 212 falls between two adjacent protruding structures and abuts against the outer side of the protruding structures, it starts to drive the cover body 100 to rotate stably.

[0076] It is worth mentioning that before the spinning head 31 cooperates with the connecting column 210, the motor 73 simultaneously drives the positioning columns 7 on both sides of the V-shaped plate 22 to rotate through the gear transmission box 74, so that the positioning columns 7 drive the cover body 100 to move downward and fall to the top of the support plate 6. During the falling process, the cover sleeve 29 always adheres to the top of the cover body 100 by gravity, and the clamping force generated by the clamping rod 43 located on the outside of the cover body 100 is not enough to push the cover body 100 at the bottom of the cover sleeve 29 horizontally, so that the support plate 6 vertically supports the cover body 100 through the ring 61, and at this time, the positioning column 7 drives the outer section 71 to rotate from a horizontal state to a vertical state, thereby releasing the positioning effect on the cover body 100, and preventing the cover body 100 from rotating during the subsequent spinning process. Friction with the V-shaped plate 22 and the positioning column 7 affects the stability.

[0077] It is worth mentioning that the above spinning method has the following advantages:

[0078] Advantage 1: Before spinning, the lid body 100 is horizontally positioned by the positioning columns 7 on both sides of the V-shaped plate 22. When spinning begins, the lid body 100 is driven downward by rotating the positioning columns 7. Without affecting the positioning accuracy of the lid body 100, the cut surface 71 on the outside of the positioning columns 7 is rotated to the outside of the lid body 100, thereby releasing the horizontal positioning of the lid body 100 and preventing the lid body 100 from rubbing against the positioning columns 7 during spinning.

[0079] Advantage 2: The clamping rod 43 located on the outside of the cover body 100 ensures the horizontal stability of the cover body 100 before spinning. Although it is close to the outside of the cover body 100 during spinning, the clamping rod 43 can rotate due to the force of the cover body 100 and will not affect the assembly of the cover body 100.

[0080] Advantage three, when the positioning column 7 drives the cover body 100 to move downward, the cover body 100 can be placed on the top of the ring 61 for support, and the cover body 100 can be accurately positioned through the ring 61 and the cover sleeve 29. On this basis, the cover body 100 is spun and assembled to ensure the assembly accuracy of the cover body 100.
