It is only for the convenience of describing the technical solution of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0034] The present application proposes a cap dispensing and gasket feeding mechanism, which is specifically as follows:

[0035] Reference can be made to Figure 1-2 , the present application is mainly used by being installed on both sides of the conveyor line 8 for conveying cosmetic caps; its main structure includes two groups of L-shaped plates 1 arranged on both sides of the conveyor line 8, a clamping mechanism 2 arranged on both sides of the L-shaped plate 1, a blocking mechanism 3 for blocking the caps on the conveyor line 8 from moving forward, a lifting mechanism 4 on the opposite side of the blocking mechanism 3, a rotating mechanism 5 that moves linearly through the lifting mechanism 4, a suction cup 6 that rotates through the rotating mechanism 5 to clamp the gasket, and a carrier 7 for carrying the gasket; the inner lid is installed on the cap through the mutual cooperation between the structures.

[0036] In addition, to cooperate with the above structure to achieve automatic control, it further includes a PLC controller 13 for automatic control, a first proximity sensor 9 installed on the side of the conveyor line 8 at the dispensing station and electrically connected to the PLC controller 13, a second proximity sensor 10 installed on the side of the conveyor line 8 at the cap insertion station, and the conveyor line 8 is also electrically connected to the PLC controller 13, and performs conveying or stopping actions according to the signals sent by the PLC controller 13. The PLC controller 13 is also electrically connected to the drivers of the dispensing shielding mechanism 11, the dispensing mechanism 101, the gasket blocking mechanism 12, the clamping mechanism 2, the lifting mechanism 4, the rotating mechanism 5, and the suction cup 6 respectively, and drives these actuators to perform corresponding actions.

[0037] Dispensing function: It can be referred to Figure 1-2 , the dispensing mechanism 101 adopts a commercially available automatic dispensing gun, and the automatic dispensing gun is electrically connected to the PLC controller 13, receives the signal for controlling opening and closing sent by the PLC controller 13, and performs the dispensing action. To control the reasonable opening of the automatic dispensing gun to achieve the dispensing work, a first proximity sensor 9 is provided on the lower side of the dispensing mechanism 101; after the first proximity sensor 9 senses the cap transported over, the data is transmitted to the PLC controller 13, and after being judged by the PLC controller 13, the conveyor line 8 is stopped, and the automatic dispensing gun is controlled to start the dispensing work; further, in order to prevent the cap from continuing to move forward due to inertia during dispensing, two sets of blocking structures identical to the structure of the blocking mechanism 3 are provided at the first proximity sensor 9, which are called the dispensing blocking mechanism 11; during operation, after the first proximity sensor 9 senses the cap transported over, the dispensing blocking mechanism 11 composed of the two sets of blocking structures extends out, separates and blocks two adjacent caps respectively to stop, so that only one cap exists at the dispensing station. Through the time delay control of the PLC controller 13, when the glue dripping is completed within the specified time, the dispensing blocking mechanism 11 retracts to release, and the PLC controller 13 controls the conveyor line 8 to restart the conveying.

[0038] It can be referred to Figure 1-2 , there are two sets of L-shaped plates 1, symmetrically installed on both sides of the conveyor line 8; a support position is formed on both sides, the conveyor line 8 is arranged between the L-shaped plates 1, and the distance between the L-shaped plates 1 is less than 1.4 times the diameter of the cap. Even if the cap is somewhat offset, the maximum offset does not exceed the radius. Therefore, the automatic dispensing gun arranged on the center line of the conveyor line 8 can always drop the glue into the cap.

[0039] It can be referred to Figure 1-2 , there are two sets of clamping mechanisms 2, symmetrically arranged on the sides of the two sets of L-shaped plates 1 away from the conveyor line 8; the clamping mechanism 2 is used to clamp the cap, playing a fixing role, so as to stably install and combine the gasket with the cap.

[0040] Among them, the clamping mechanism 2 includes a first cylinder 21 and a moving plate 22; the output end of the first cylinder 21 is connected to the moving plate 22, and the first cylinder 21 drives the moving plate 22 to move linearly through the inner wall of the L-shaped plate 1; when in use, a fixing plate is provided to fix the first cylinder 21, and the first cylinder 21 is installed and supported by the fixing plate; secondly, when installing, the distance between the fixing plate and the L needs to meet the required range for the linear movement of the moving plate 22. The driver of the clamping mechanism 2 is electrically connected to the PLC controller 13, and the PLC controller 13 controls the clamping mechanism 2 to clamp or release the bottle cap. Here, because it is necessary to align the gasket up and down with precision requirements, a pair of clamping mechanisms 2 symmetrically arranged on both sides are used. When the pair of clamping mechanisms 2 move towards the middle, the bottle cap can be exactly fixed directly below the gasket to complete the gasket insertion action.

[0041] Further, when the moving plate 22 moves through the movement of the first cylinder 21, the moving plate 22 moves through the inner part of the L-shaped plate 1. A bent arc 221 is formed by inward depression at one place where the moving plate 22 passes through the L-shaped plate 1, and the bent arc 221 fits the half-side edge of the bottle cap; during operation, the first cylinders 21 on both sides move synchronously towards the direction of the conveyor line 8; thus, the bent arcs 221 on the two moving plates 22 that move symmetrically come to the left and right sides of the bottle cap to perform clamping and fixing.

[0042] For reference Figure 1-2 , before the clamping mechanism 2 achieves stable clamping, it is necessary for the bottle cap to stop moving forward continuously on the conveyor line 8; to achieve this operation, a blocking mechanism 3 is provided. Here, the blocking mechanism 3 is called the gasket insertion blocking mechanism 12, and the gasket insertion blocking mechanism 12 is arranged on one side of one of the two groups of L-shaped plates 1; the output end of the gasket insertion blocking mechanism 12 passes through the inner wall of the L-shaped plate 1 and is located above the conveyor line 8 to block the flow of the bottle cap.

[0043] The dispensing blocking mechanism 11 and the gasket insertion blocking mechanism 12 both adopt the structure of the blocking mechanism 3. The blocking mechanism 3 includes a second cylinder 31 and a blocking rod 32; the output end of the second cylinder 31 is connected to the blocking rod 32; the second cylinder 31 drives the blocking rod 32 to move linearly through the moving plate 22 and the inner wall of the L-shaped plate 1; when installing, both the second cylinder 31 and the first cylinder 21 are installed and supported on the same fixing plate. The drivers of the first cylinder 21 and the second cylinder 31 are both electrically connected to the PLC controller 13 and are controlled by the PLC controller 13.

[0044] Before the clamping mechanism 2 moves, first, the second cylinder 31 drives the blocking rod 32 to penetrate into the moving plate 22 and the inner wall of the L-shaped plate 1, and the penetrated end is located above the conveyor line 8; to block the bottle cap on the conveyor line 8. When the clamping mechanism 2 clamps the bottle cap, the second cylinder 31 retracts again to the position before penetration.

[0045] Pad feeding function: A second proximity sensor 10 is also provided at the clamping mechanism 2. After the second proximity sensor 10 senses the bottle cap, it transmits the data to the PLC controller 13, which quickly controls the second cylinder 31 to work (the pad feeding blocking mechanism 12), prompting the blocking rod 32 to extend to block the bottle cap. After the blocking rod 32 extends, the first cylinder 21 starts to work to control the moving plate 22 to perform the clamping work.

[0046] For reference Figure 1-2 , after the operations of the clamping mechanism 2 and the blocking mechanism 3, the bottle cap is in a stable clamping state on the conveyor line 8. The lifting mechanism 4, the rotating mechanism 5, and the suction cup 6 are set to clamp and transfer the gasket in the carrier 7 to the upper side of the bottle cap to complete the assembly work;

[0047] Among them, the lifting mechanism 4 is provided on one side of the other set of L-shaped plates 1; the rotating mechanism 5 is provided on the slide rail of the lifting mechanism 4, and the suction cup 6 is provided at one end of the rotating mechanism 5 away from the lifting mechanism 4; the rotating mechanism 5 first rotates the suction cup 6 to make the suction cup 6 face upward and correspond to the output end of the upper carrier 7 up and down. Secondly, the lifting mechanism 4 drives the rotating mechanism 5 to perform a linear upward movement until it contacts the carrier 7 and takes out the gasket in the carrier 7. Then, the lifting mechanism 4 drives the rotating mechanism 5 to perform a linear downward movement again. When descending, the rotating mechanism 5 rotates the suction cup 6 to be inclined; until there is a bottle cap on the lower side and after the operations of the clamping mechanism 2 and the blocking mechanism 3, the rotating mechanism 5 rotates the suction cup 6 completely vertically downward, and then the lifting mechanism 4 performs a linear downward movement to assemble the gasket on the suction cup 6 onto the bottle cap. After that, the lifting mechanism 4 rises again to repeat the above operation steps.

[0048] Among them, it should be noted that the lifting mechanism 4, the rotating mechanism 5, and the suction cup 6 are all existing relatively mature technologies. The lifting mechanism 4 can be any one of the existing electric elevators or cylinders; the rotating mechanism 5 can be any one of the existing rotating motors or servo motors.

[0049] The drivers of the lifting mechanism 4, the rotating mechanism 5, and the suction cup 6 are all electrically connected to the PLC controller 13 and are controlled by the PLC controller 13 to perform corresponding actions. When the lifting mechanism 4 rises, it first controls the rotating mechanism 5 to perform a 180-degree rotation. The lifting mechanism 4 descends three times. The first time it descends one-third, the rotating mechanism 5 performs a 160-degree rotation. The second time it descends one-third, the rotating mechanism 5 performs a 30-degree rotation. At this time, the side of the suction cup 6 with the gasket adsorbed corresponds to the bottle cap on the lower side up and down; the third time it descends one-third again, the rotating mechanism 5 does not move. At this time, the suction cup 6 moves vertically downward to contact the bottom bottle cap and bonds the gasket in the bottle cap. Through the time delay control of the PLC controller 13, when the pad feeding is completed within the specified time, the pad feeding blocking mechanism 12 retracts, the clamping mechanism 2 releases, and the PLC controller 13 controls the conveyor line 8 to restart the conveying.

[0050] for reference Figure 1-2 The carrier 7 is provided at the top of the lifting mechanism 4 and is used to carry the gasket. The lower output end of the gasket corresponds to the suction cup 6 up and down.

[0051] Among them, the carrier 7 includes a mounting plate 71, a blocking bar 72 and a material bin 73. The mounting plate 71 is installed at the top of the lifting mechanism 4; the blocking bar 72 is fixedly installed on the upper surface of the mounting plate 71; the material bin 73 is communicatively provided at the bottom of the mounting plate 71; the gasket is pre-placed in the blocking bar 72, and the middle part of the blocking bar 72 is the communication place between the material bin 73 and the mounting plate 71, so that the gasket will enter the material bin 73; an opening is provided at the bottom of the material bin 73, and the diameter of the opening is smaller than the diameter of the gasket; when the suction cup 6 is displaced to the lower side of the opening, the suction cup 6 is prompted to adsorb and remove a gasket from the bottom of the material bin 73.

[0052] In order to trigger the reminder function when there are not many gaskets, a photoelectric sensor is provided on the mounting plate 71. The photoelectric sensor is connected to the same controller as the first proximity sensor 9 and the second proximity sensor 10; the photoelectric sensor can detect the blocking of light by an object. When the gasket descends to be completely not exposed, the sensor can detect the change in the blocked light and trigger corresponding actions or reminders.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
