Description

Technical Field

[0001] The present invention relates to the technical field of assembly machines, and in particular to an assembly device for cosmetic packaging bottle caps. Background Art

[0002] Before installing existing cosmetic bottle caps, a PE gasket must be installed inside them to ensure a seal after being screwed onto the bottle body, thereby preventing the liquid in the bottle from leaking. There are currently two ways to assemble the PE gasket inside the bottle cap: one is to directly press the PE gasket into the bottle cap, and the other is to press the PE gasket into the bottle cap and connect it with an adhesive. Currently, when connecting with adhesive, the bottle cap is placed on a jig with a notch matching the bottle cap on top. After the jig is moved to the corresponding station, the bottle cap or gasket is placed thereon. After a long period of repeated friction with the bottle cap, the inner diameter of the jig's notch will increase. At this time, after the bottle cap is placed inside the notch of the jig, the position of the bottle cap will shift due to vibration during the movement of the jig, which makes it impossible to ensure that the bottle cap component is in the middle of the notch. If the gasket position shifts during this process, the glue on the gasket will be left on the thread of the inner cap after it contacts the thread of the inner cap, affecting the effect of the installation of the bottle cap and the bottle body, and affecting the sealing and isolation effect of the final product.

The clamping head 711 is an inverted L-shaped structure, and the bottom end of the head of the clamping head 711 is higher than the upper surface of the placement seat 6. The clamping head 711 can move inward close to the placement seat 6, thereby positioning and clamping the gasket located above the placement seat 6; The clamping head 711 is provided with a rubber elastic member. When the clamping head 711 is reset, the rubber elastic member contacts the bottle cap and can be deformed without causing pressure damage thereto.

[0021] The driving structure 8 slides up and down on the lifting ring 81 in the mounting cavity of the placement seat 6. The lifting ring 81 is provided with a plurality of mounting notches 811 distributed in a circular array. A driving rod 812 is provided in the mounting notches 811. The driving rod 812 is slidably inserted into the driving groove. The rotating seat 51 is penetrated by two openings at the top and bottom, and a lifting rod 83 is inserted into the opening for sliding up and down. The upper end of the lifting rod 83 is fixed to the lifting ring 81, and the bottom end of the lifting rod 83 passes through the opening and is placed under the rotating seat 51. A contact roller 85 is rotatably installed between the bottom ends of the two lifting rods 83 through an axle pin. The contact roller 85 is in rolling contact with the driving ring 52. A fixed ring 841 is fixed under the lifting rod 83, and a downward compression spring 84 is sleeved on the lifting rod 83. The two ends of the downward compression spring 84 are respectively in contact with the fixed ring 841 and the rotating seat 51. The downward compression spring 84 makes the lifting rod 83 always have a tendency to move downward, thereby making the lifting ring 81 have a tendency to move downward.

[0022] Reference Figure 5 、 Figure 6 as well as Figure 9The driving groove includes a lifting groove 72 vertically distributed above the side of the moving block 71, the lower end of the lifting groove 72 is provided with a clamping groove 73 inclined outward, the lower end of the clamping groove 73 is provided with a holding groove 74 facing vertically downward, and an inwardly inclined away groove 75 is provided below the holding groove 74. The lower end of the away groove 75 is provided with an extending groove distributed vertically downward. The distance between the upper end of the clamping groove 73 and the axis of the lifting ring 81 is smaller than the distance between the lower end of the clamping groove 73 and the axis of the lifting ring 81, and the distance between the upper end of the away groove 75 and the axis of the lifting ring 81 is larger than the distance between the lower end of the away groove 75 and the axis of the lifting ring 81. The contact roller 85 of the driving structure 8 located on the gasket area 11 contacts the lifting surface 521. The driving rod 812 of the driving structure 8 is located at the intersection of the lifting groove 72 and the clamping groove 73. Then, when the rotating seat 51 intermittently rotates one-fifth of a circle, the driving structure 8 moves from the gasket area 11 toward the coating area 12. The contact roller 85 will move from above the feeding surface 522 to the second inclined surface, and then move from the second inclined surface to the clamping surface 523. When moving along the second surface of the inclined plane, since the height of the loading surface 522 is higher than the clamping surface 523, the lifting ring 81, the driving rod 812, the lifting rod 83, and the contact roller 85 will also gradually move downward under the action of the downward pressure spring 84. The driving rod 812 moving downward will slide along the clamping groove 73 and push the moving block 71 to move inwardly close to the placement seat 6. The multiple moving blocks 71 move inwardly close to the placement seat 6 synchronously, thereby being able to center the gasket above the placement seat 6 so that the gasket is directly above the placement seat 6. When the contact roller 85 moves above the clamping surface 523, the driving rod 812 is located at the intersection of the clamping groove 73 and the holding groove 75, and the clamping heads 711 on the moving blocks 71 clamp and position the gasket above the placement seat 6. When the contact roller 85 moves along the clamping surface 523, the height of the end connecting the clamping surface 523 with the inclined surface 2 is higher than the height of the end connecting the clamping surface 523 with the away surface 524. The height of the contact roller 85 will gradually decrease. At this time, the driving rod 812 will move vertically downward along the holding groove 74, and the position of the moving block 71 remains unchanged. In this stage, the multiple clamping heads 711 can always ensure the positioning of the gasket, which is convenient for subsequent glue coating operations. When the placement seat 6 moves to just above the glue coating area 12, the driving rod 812 is at the intersection of the holding groove 74 and the clamping groove 73; After the gasket is coated with glue, the rotating seat 51 rotates another fifth of a circle, and the driving structure 8 will also rotate one fifth of a circle. The gasket located on the coating area 12 will move to the pressure covering area 13. During this process, the contact roller 85 in the driving structure 8 will move from above the clamping surface 523 to the away surface 524. When the surface of the clamping surface 523 moves, under the action of the lower pressure spring 84, the lifting ring 81, the driving rod 812, the lifting rod 83, and the contact roller 85 will continue to move downward. The downward moving driving rod 812 will slide along the away groove 74, thereby pushing the moving block 71 to move outward away from the placement seat 6. Multiple moving blocks 71 move outward away from the placement seat 6 synchronously, and there is a certain distance between the multiple clamping heads 711 and the placement seat 6. When the placement seat 6 with the glue-coated gasket is moved to the top of the capping area 13, there is a certain distance between the multiple clamping heads 711 and the placement seat 6. At this time, the grabbing robot in the bottle cap loader 4 grabs the bottle cap and buckles it directly on the placement seat 6. The gasket can be directly pressed onto the top of the bottle cap and bonded.

[0023] The placement seat 6 is penetrated from top to bottom to form a plurality of lifting holes 62 distributed in a circular array, and a plurality of lifting rods 82 are provided on the lifting ring 81, and the plurality of lifting rods 82 correspond to the plurality of lifting holes 62 one by one; When the contact roller 85 is above the loading surface 522, the lifting rod 82 is inserted into the lifting hole 62, and the top of the lifting rod 82 is flush with the upper surface of the placement seat 6. When the contact roller 85 is above the lifting surface 521, the top of the lifting rod 82 passes through the lifting hole 62 and is placed above the placement seat 6. When the gasket and bottle cap are pressed and assembled, the rotating seat rotates one-fifth of a circle again. At this time, the driving structure 8 will also rotate one-fifth of a circle, and the placement seat 6 and the bottle cap located on the pressing area 13 will move to the unloading area 14. During this process, the contact roller 85 in the driving structure 8 will move from above the distance surface 524 to the inclined surface three, and from the inclined surface three to the lifting surface 521. When moving along the inclined surface four, since the height of the distance surface 524 is lower than the height of the lifting surface 521, the lifting ring 81 and the driving rod 812 will return along the original path, and the height of the lifting ring 81 is better than the height when it is located at the loading surface 522. The top end of the lifting rod 82 passes through the lifting hole 62 and is placed above the placement seat 6, which can lift the bottle cap to prevent the gasket from being adsorbed on the placement seat 6, and to prevent the gasket from sticking to the placement seat 6 when the bottle cap is unloaded, causing the gasket to fall off.

[0024] Reference Figure 5 - Figure 10The adsorption part 9 includes a fixing sleeve 91 fixed to the top of the mounting cavity of the placement seat 6, the fixing sleeve 91 is inserted into the circular hole of the lifting ring 81, and the lower end opening of the fixing sleeve 91 is designed to form a circular opening, and a piston 92 is inserted into the fixing sleeve 91 to slide up and down. A pull rod 93 is fixed to the lower end of the piston 92, and the lower end of the pull rod 93 passes through the circular opening and is placed under the outside of the fixing sleeve 91, and a lower pressure ring 94 is fixed under the pull rod 93. A lifting spring 95 is sleeved on the pull rod 93, and the upper and lower ends of the lifting spring 95 are respectively abutted against the lower pressure ring 94 and the rotating seat 51. The rotating seat 51 is penetrated up and down to form a through hole, which is placed just below the pull rod 93 to facilitate the downward movement of the pull rod 93. The lifting spring 95 makes the lower pressure ring 94 and the pull rod 93 always have a tendency to move upward. The connection between the fixing sleeve 91 and the placement seat 6 is sealed, and the piston 92 and the inner wall of the fixing sleeve 91 are sealed.

[0025] The outer diameter of the lower pressure ring 94 is larger than the inner diameter of the lifting ring 81. A plurality of adsorption holes 61 are provided on the placement seat 6. The adsorption holes 61 are connected to the inner cavity of the fixing sleeve 91. After the lifting ring 81 moves downward to a certain extent, the downward movement of the lifting ring 81 can cause the lower pressure ring 94 to move downward together, thereby causing the piston 92 to move downward. The downward moving piston 92 increases the internal space of the fixing sleeve 91 and reduces the air pressure, so that the gasket can be pressed onto the placement seat 6 by the air pressure above the placement seat 6. After the clamping head 711 moves away from the placement seat 6, the gasket can also be fixed without affecting the normal downward pressure of the bottle cap.

[0026] Working principle: In the initial state, an empty placement seat 6 is located in the gasket area 11, and the placement seat 6 is directly below the grabbing manipulator of the gasket loader 2. The grabbing manipulator of the gasket loader 2 grabs a gasket and places it on top of the placement seat 6. Then, the placement seat 6 and the rotating seat 51 rotate one-fifth of a circle under the action of the precision intermittent divider and move to the glue coating area 12. When the driving structure 8 in the placement seat 6 moves from the gasket area 11 toward the glue coating area 12, the contact roller 85 will move from above the loading surface 522 to the second inclined surface, and then move from the second inclined surface to the clamping surface 523; When moving along the second surface of the inclined plane, since the height of the loading surface 522 is higher than the clamping surface 523, the lifting ring 81, the driving rod 812, the lifting rod 83, and the contact roller 85 will also gradually move downward under the action of the downward pressure spring 84. The driving rod 812 moving downward will slide along the clamping groove 73 and push the moving block 71 to move inwardly close to the placement seat 6. The multiple moving blocks 71 move inwardly close to the placement seat 6 synchronously, thereby being able to center the gasket above the placement seat 6 so that the gasket is directly above the placement seat 6. When the contact roller 85 moves above the clamping surface 523, the driving rod 812 is located at the intersection of the clamping groove 73 and the holding groove 74, and the clamping heads 711 on the multiple moving blocks 71 clamp and position the gasket above the placement seat 6. Then, the glue coating machine 3 performs glue coating on the gasket, and at this time, the lower surface of the lifting ring 81 contacts the upper surface of the fixed ring 841. After the gasket is coated with glue, the rotating seat 51 rotates one-fifth of a circle again and moves to the top of the pressure cover area 13. The driving structure 8 will also rotate one-fifth of a circle, and the gasket located on the coating area 12 will move to the pressure cover area 13. During this process, the contact roller 85 in the driving structure 8 will move from above the clamping surface 523 to the away surface 524. When the clamping surface 523 moves, the height of the end connecting the clamping surface 523 and the inclined surface 2 is higher than the height of the end connecting the clamping surface 523 and the away surface 524. Under the action of the lower pressure spring 84, the lifting ring 81 and the driving rod 812 The lifting rod 83 and the contact roller 85 will also continue to move downward, and the height of the contact roller 85 will gradually decrease. At this time, the driving rod 812 will move vertically downward along the holding groove 74, and the position of the moving block 71 will remain unchanged. In this stage, the multiple clamping heads 71 ​​can always ensure the positioning of the gasket. After a period of time, the driving rod 812 moving downward will slide along the away groove 75, thereby pushing the moving block 71 to move outward away from the placement seat 6. The multiple moving blocks 71 move outward away from the placement seat 6 synchronously, and there is a certain distance between the multiple clamping heads 711 and the placement seat 6. When the driving rod 812 moves along the holding groove 74 and away from the groove 75, the downwardly moving lifting ring 81 will also press the lower pressure ring 94 downward to make it move downward together. The downwardly moving lower pressure ring 94 will cause the piston 92 to move downward. The downwardly moving piston 92 increases the internal space of the fixing sleeve 91 and reduces the air pressure, so that the gasket can be pressed onto the placement seat 6 by the air pressure above the placement seat 6. After the clamping head 711 moves away from the placement seat 6, the gasket can still be fixed without affecting the normal downward pressure of the bottle cap. When the placement seat 6 with the glue-coated gasket is moved to the top of the capping area 13, there is a certain distance between the multiple clamping heads 711 and the placement seat 6. At this time, the grabbing robot in the bottle cap loader 4 grabs the bottle cap and buckles it directly on the placement seat 6. The gasket can be directly pressed onto the top of the inner part of the bottle cap and bonded. After that, the rotating seat 51 rotates one-fifth of a circle again and moves from the capping area 13 to above the unloading area 14. The driving structure 8 will also rotate one-fifth of a circle. The gasket located on the capping area 13 will move to the unloading area 14. During this process, the placement seat 6 and the bottle cap located on the capping area 13 will move to the unloading area 14. The contact roller 85 in the driving structure 8 will move from above the away surface 524 to the inclined surface three, and then move from the inclined surface three to the lifting surface 521. When moving along the inclined surface three, since the height of the away surface 524 is lower than the height of the lifting surface 521, Therefore, the lifting ring 81 and the driving rod 812 will return along the original path, and the height of the lifting ring 81 is higher than the height when it is located on the loading surface 522. When the contact roller 85 is above the lifting surface 521, the driving rod 812 is placed at the uppermost part of the lifting groove 72, and the top end of the lifting rod 82 passes through the lifting hole 62 and is placed above the placement seat 6. The top end of the lifting rod 82 passes through the lifting hole 62 and is placed above the placement seat 6, which can lift the bottle cap to prevent the gasket from being adsorbed on the placement seat 6, and prevent the gasket from sticking to the placement seat 6 and falling off when the bottle cap is unloaded. After unloading is completed, the rotating seat 51 rotates again so that the placement seat 6 moves from the unloading area 14 to above the gasket area 11, and the driving structure 8 will also rotate accordingly. During this process, the height of the lifting ring 81 decreases, and the driving rod 812 moves to the intersection of the jacking groove 72 and the clamping groove 73. The multiple clamping heads 711 move away from each other, waiting for the gasket to be loaded again, and the above operation is repeated.

[0027] By arranging a placement seat 6 above the rotating seat 51, a plurality of synchronously moving clamping members 7 are arranged on the placement seat 6, the clamping members 7 are connected to the driving structure 8, and the driving structure 8 is connected to the driving ring 52. Before the placement seat 6 moves to the glue coating area 12, the clamping members 7 can center and clamp the gasket, thereby facilitating the glue coating operation and improving the accuracy of subsequent pressing. In addition, during the pressing process, the clamping members 7 can stay away from the placement seat 6 to avoid contact with the bottle cap, which may cause the bottle cap to be unable to be pressed down. By arranging an adsorption member 9 above the placement seat 6 and connecting the adsorption member 9 to the driving structure 8, the clamping member 7 can be moved away from the gasket only after the adsorption member 9 adsorbs and fixes the gasket, and the position of the gasket can be kept fixed when the bottle cap is pressed down, thereby improving the accuracy of the press-fit assembly; By arranging a lifting rod 82 above the lifting ring 81, when the gasket and bottle cap are assembled and need to be unloaded, the lifting rod 82 can push the gasket and bottle cap to move upward and away from the placement seat 6, thereby preventing the gasket from sticking to the placement seat 6 and falling off when the bottle cap is unloaded.
