Description

Technical Field

[0001] The invention belongs to the field of bottle cap manufacturing, and in particular relates to a cosmetic packaging bottle cap assembly machine. Background Art

[0002] With the development of the times, the sales volume of cosmetics has been increasing, which has also led to an increase in the sales volume of cosmetic packaging bottle caps. Existing cosmetic bottle caps are mostly composed of an outer cover and an inner cover. The outer cover often has a brand logo on its surface, and the inner cover and the outer cover have positioning parts that are positioned and matched with each other. Their logos and positioning parts are fixed in position because they are produced through molds during production. They can be installed by identifying the position of the positioning parts during installation. Existing installation methods mostly use manual alignment and then extrusion to match, which is inefficient.

[0003] With the development of the cosmetics industry, the requirements for the sealing of cosmetic bottle caps on the market are also constantly increasing. Therefore, during the production process of today's cosmetic bottle caps, a layer of gasket will be added to the inside of the bottle cap. By adding the gasket to the inside of the bottle cap, the bottle cap will not directly contact the bottle mouth when in use, thereby playing a sealing and isolating role. When the gasket in the bottle cap is installed, the gasket is attached to the position of the bottle cap where the gasket should be attached through the glue on the gasket. If the position of the gasket is offset during this process, the glue on the gasket will be left on the threads of the inner cap after contacting the threads of the inner cap, affecting the installation effect of the bottle cap and the bottle body, and affecting the sealing and isolating effect of the final product. Therefore, if manual labor is used, low installation efficiency will easily lead to defective products. Summary of the invention

The inner cover 90 is displaced to the corresponding position at the workstation 13. After the placement, the control device 1 controls the first electric clamp 19 to move to the clamping position through the electric slide. The control device 1 controls the clamping jaws of the first electric clamp 19 to clamp the inner cover 90 and fix the position of the inner cover 90. After the film loading mechanism 4 has affixed the gasket 97, the control device 1 controls the clamping jaws of the first electric clamp 19 to release the inner cover 90 to complete the film loading process. The control device 1 controls the first electric clamp 19 to restore the position through the electric slide displacement, providing space for the work station 13 to drive the inner cover 90 to move. The pressing mechanism 6 squeezes the gasket 97 after placing the gasket 97 on the inner cover 90. The flip mechanism 7 includes a second bracket 20, and a third bracket 21 is slidably connected to the second bracket 20. The sliding connection method can be achieved by setting up an electric slide that moves up and down. The third A rotating electric clamp 22 is provided on the bracket 21 in a sliding connection. The sliding connection can be achieved by setting up an electric slide that can be displaced back and forth in the direction of the workstation 13. The third bracket 21 is provided with a fifth cylinder push rod 102 on the side biased to the workstation 13. After the workstation 13 displaces the inner cover 90 with the cover opening facing downward to the corresponding position, the control device 1 controls the rotating electric clamp 22 to move to the clamping position through the electric slide. The control device 1 controls the clamping jaws of the first electric clamp 19 to clamp the inner cover 90. The control device 1 controls the second bracket 20 to drive the rotating electric clamp 22 to move upward to the position where the clamp can be rotated through the electric slide. The control device 1 controls the rotating electric clamp 22 to rotate the clamp, flipping the direction of the inner cover 90, with the cover opening of the inner cover 90 facing downward.The control device 1 controls the rotating electric clamp 22 to move the inner cover 90 to the position where the inner cover 90 should be placed after it is turned over by the electric slider. The rotating electric clamp 22 releases the clamp, and the third cylinder push rod 102 moves to the upper part of the inner cover 90 with the cover opening facing downward. The fifth cylinder push rod 102 extends to squeeze the inner cover 90, and the fifth cylinder push rod 102 is recovered. The control device 1 controls the rotating electric clamp 22 and the fifth cylinder push rod 102 to restore the position through the electric slide displacement, providing space for the work station 13 to drive the displacement of the inner cover 90. The second positioning mechanism 8 includes a fourth bracket 23, and the fourth bracket The outer cover placing mechanism 9 comprises a base 25, a material placing area 26 is provided on the base 25, a second mechanical arm 27 is provided on one side of the material placing area 26, a second suction cup 28 is provided at the connecting end of the second mechanical arm 27, a third visual sensor 29 is provided on the second mechanical arm 27, the second mechanical arm 27 can rotate the outer cover 91 in a plane, and the third visual sensor 29 can identify the outer cover 91. The third visual sensor 29 provides the identification position to the control device 1, and locates the positioning part 100 on the outer cover 91 through the identification position. Through the positioning of the inner cover 90 and the outer cover 91, the control device 1 controls the second mechanical arm 27 to suck up the outer cover 91 and place it to the matching position with the inner cover 90. After the placement, the control device 1 controls the second mechanical arm 27 to release the outer cover 91 and restore the original state, providing a space for the station 13 to drive the displacement of the inner cover 90 and the outer cover 91. The capping mechanism 10 puts the outer cover 91 on the inner cover 90 and squeezes the outer cover 91 after they match each other. 10 can be achieved by setting up an electric push rod to squeeze the inner cover 90 and the outer cover 91. The lower cover mechanism 11 can unload the finished product on the workstation 13 after the inner cover 90 and the outer cover 91 are installed. The lower cover mechanism 11 can be manually implemented, and the inner cover 90 and the outer cover 91 are installed in a mutually matching manner by identifying the positioning position 100 of the inner cover 90 and the mark of the outer cover 91. At the same time, by identifying the position of the gasket 97 and the position of the gasket 97 of the inner cover 90, the gasket 97 is accurately attached to ensure that the gasket 97 is attached to the position of the gasket, so as to achieve the effect of sealing and isolation.

[0027] In this example, the station 13 of the cosmetic packaging bottle cap assembly machine includes a first positioning seat 30 and a second positioning seat 31. The first positioning seat 30 is provided with a detection hole 32. The first positioning seat 30 can be used to fix the inner cover 90 with the cover opening facing upward, and the second positioning seat 31 can be used to fix the inner cover 90 with the cover opening facing downward. An inner cover detection mechanism 33 is provided between the feeding mechanism 3 and the upper film mechanism 4. The inner cover detection mechanism 33 includes a fifth bracket. A sixth bracket 34 is slidably connected to the fifth bracket. This sliding connection method can be achieved by setting up an electric slide that can move up and down. A detection rod 35 that can pass through the detection hole 32 is slidably connected to the sixth bracket 34. This sliding connection method can be achieved by setting up a path on the sixth bracket 34 that can pass through the detection rod 35. A detection piece 36 is provided on the detection rod 35. The detection piece 36 limits the detection rod 35 from completely passing through the sixth bracket 34 downward.

A detection piece 36 is provided above the detection piece 36. The detection block 37 is provided with a detection port 38 through which the detection piece 36 can pass. The detection block 37 is fixed on the sixth bracket 34. The fixing method can be fixed by screws and nuts. After the first positioning seat 30 is moved to the corresponding position, the sixth bracket 34 is moved downward. When the inner cover 90 is arranged on the first positioning seat 30, due to the obstruction of the inner cover 90, the detection rod 35 slides upward, and the detection piece 36 is moved to the detection port 38. The detection port 38 outputs a high level to the control device 1. After receiving it, the control device 1 knows that there is an inner cover 90 at the station 13. When there is no inner cover 90 on the first positioning seat 30, because there is no obstruction of the inner cover, the detection rod 35 passes through the detection hole 32, and the detection piece 36 is not at the detection port 38 position. The detection port 38 outputs a low level to the control device 1. After receiving it, the control device 1 knows that there is no inner cover 90 at the station 13. After the detection, the control device 1 controls the sixth bracket 34 to move upward, providing a space for the station 13 to drive the displacement of the inner cover 90, thereby realizing the function of detecting whether there is an inner cover 90 on the station 13.

[0028] In this example, the pressing mechanism 6 includes a seventh bracket 56, and the seventh bracket 56 is provided with a first cylinder push rod 39 above the work station 13 and facing the work station 13.

[0029] In this example, the capping mechanism 10 includes an eighth bracket 40, and the eighth bracket 40 is provided with a second cylinder push rod 41 above the work station 13 and facing the work station 13. When the work station 13 moves to the corresponding position, the control device 1 controls the second cylinder push rod 41 to squeeze the outer cover 91, and restores the original position after squeezing, thereby ensuring a firm fit between the inner cover 90 and the outer cover 91.

[0030] In this example, the lower cover mechanism 11 includes a ninth bracket 42, which is slidably connected to a tenth bracket 43. This sliding connection can be achieved by setting up an electric slide that can move back and forth in the direction of the workstation 13. The tenth bracket 43 is slidably connected to an eleventh bracket 44. This sliding connection can be achieved by setting up an electric slide that can move up and down and back and forth. The eleventh bracket 44 is respectively provided with a second electric clamp 45 and a third cylinder push rod 46 inward and outward toward the turntable 2. The third cylinder push rod 46 is provided with a third electric clamp 47 at the connecting end. A placement platform 48 is provided under the third electric clamp 47. 48 includes a disc 49 and a fourth cylinder push rod 50, the disc 49 is fixed on the connecting end of the fourth cylinder push rod 50, when the finished product on the station 13 reaches the corresponding position, the control device 1 controls the eleventh bracket 44 to move downward, and the second electric clamp 45 clamps the finished product. After clamping, the control device 1 controls the eleventh bracket 44 to move upward. After the eleventh bracket 44 moves upward, the control device 1 controls the tenth bracket 43 to move to the outside of the station 13, the control device 1 controls the fourth cylinder push rod 50 to push the disc 49 upward, and after the second electric clamp 45 moves the finished product to the top of the disc 49, the control device 1 controls the eleventh bracket 44 moves downward, and after it falls on the disc 49, the control device 1 controls the second electric clamp 45 to release the finished product, the disc 49 falls, and the second electric clamp 45 returns to its original position. The third electric clamp 47 comes above the disc 49, and the control device 1 controls the third cylinder push rod 46 to push the third electric clamp 47 to move downward. After the disc 49 and the third electric clamp 47 fall to the same height, the control device 1 controls the third electric clamp 47 to clamp the finished product. The control device 1 controls the third cylinder push rod 46 to drive the third electric clamp 47 to move upward. After the second electric clamp 45 clamps the next finished product again, the control device 1 controls the third cylinder push rod 46 to push the third electric clamp 47 to move upward. The device 1 controls the eleventh bracket 44 to move upward. After the eleventh bracket 44 moves upward, the control device 1 controls the tenth bracket 43 to move toward the outside of the workstation 13, and the third electric clamp 47 moves to above the unloading area. The control device 1 controls the third cylinder push rod 46 to push the third electric clamp 47 to move downward. The third electric clamp 47 moves to the unloading area. The control device 1 controls the third electric clamp 47 to release the finished product. After the finished product is unloaded, the control device 1 controls the third electric clamp 47 to repeat the above actions after the second electric clamp 45 places the finished product on the disc 49. This design can achieve the displacement of the finished product to the required position height when unloading.

The connection method can be that the inner cover detection mechanism 33, the sheet loading mechanism 4, the first positioning mechanism 5, the sheet pressing mechanism 6, the flip cover mechanism 7, the second positioning mechanism 8, the outer cover placing mechanism 9, the cover pressing mechanism 10 and the lower cover mechanism 11 are all connected and positioned with the turntable 2 by screws and nuts, and at the same time, the distances and directions between the positions of the positioning holes are the same. This design realizes the replaceability of the mechanism and improves the versatility. When there is a better process, the mechanism position can be replaced in time without having to design the position from scratch, thereby reducing the difficulty of optimization.

[0032] In this example, the turntable 2 is provided with fixed columns 51 of the same number as the workstations 13, and the first placement position 52 and the second placement position 53 are both provided with limiting grooves 54 that cooperate with the fixed columns 51.
