[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention 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 invention.

[0029] In the description of the present invention, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] As Figure 1-9 shown, a continuous cap dropping mechanism of the present invention includes a platen 1, a plurality of feeding components 2 are arranged on the platen 1, a cover supporting plate 3 is arranged below each feeding component 2, an isolation component 4 is connected to the bottom of the cover supporting plate 3, a plurality of vacuum suction cups 5 are arranged below the isolation component 4, the vacuum suction cups 5 are installed on a flipping component 6, and the flipping component 6 is connected to a lifting component 7. The lifting component 7 is used to drive the flipping component 6 to flip and lift.

[0031] In the technical solution of the present invention, a plurality of blanking components 2 regularly distributed above the platen 1, as the initial storage unit of the cover body, can batch reserve cover bodies of different specifications. A cover support plate 3 is correspondingly arranged directly below each blanking component 2. When the blanking component 2 releases the cover body, the cover support plate 3 can quickly and stably receive the cover body, prevent the cover body from falling or shifting, ensure that the cover body is in a preset position, and enable the cover body to be smoothly docked with the vacuum suction cup 5 through the isolation component 4. A plurality of vacuum suction cups 5 serve as the actuating elements for directly grasping the cover body. The lifting component 7 can realize two-way motion control of the flipping component 6, drive the flipping component 6 to perform precise lifting motion in the vertical direction, ensure that the suction cup can accurately move and fit on the bottom of the cover body. At the same time, the lifting component 7 can also drive the flipping component 6 to complete the flipping action. After the vacuum suction cup 5 grabs the cover body, the flipping component 6 is driven by the lifting component 7 to flip, and accurately place the cover body on the target product, completing an efficient and stable cover dropping operation. Compared with the traditional cover dropping mechanism, it abandons the disadvantage of the fixed position of the suction cup and the driving shaft, avoids the problem of asynchronous lifting caused by a large number of suction cups, greatly improves the accuracy and efficiency of the cover dropping work, and can be widely applied to the capping operations of various products, having significant technical advantages and practical value.

[0032] Among them, the vacuum suction cup 5 can be connected to an external vacuum pump through an air extraction pipe.

[0033] As Figure 3 and Figure 4 shown, the isolation component 4 includes a push-pull rod 41. One end of the push-pull rod 41 is connected to a telescopic member 42. The telescopic member 42 is installed at the bottom of the platen 1. A plurality of clamping members 43 are connected to the push-pull rod 41. The clamping members 43 are rotatably connected to the cover support plate 3.

[0034] Specifically, by installing the telescopic member 42 at the bottom of the platen 1, the telescopic member 42 reciprocates to drive the horizontal movement of the push-pull rod 41. When the push-pull rod 41 moves, it will drive the adjacent clamping members 43 to act synchronously, providing a reliable clamping force to clamp the cover body below the cover support plate 3, so that the vacuum suction cup 5 can only adsorb one cover body, using mechanical force to break the vacuum adsorption interface between the cover bodies, further preventing adhesion. Through the active intervention of the isolation component 4, the vacuum adsorption state between adjacent cover bodies is broken, realizing single cover separation, and significantly improving the yield and operation efficiency of the packaging production line.

[0035] Among them, the clamping member 43 clamps the penultimate layer of cover bodies, the vacuum suction cup 5 adsorbs the last layer, and the telescopic member 42 of the cover body can be a telescopic cylinder or an electric telescopic rod.

[0036] As Figure 3 and Figure 4As shown, the clamping member 43 includes a rotating plate 431. The middle of the rotating plate 431 is rotatably connected to the cover support plate 3. The two ends of the rotating plate 431 are respectively hinged with a first connecting plate 432 and a second connecting plate 433. One end of the first connecting plate 432 away from the rotating plate 431 is hinged with a first clamping plate 434, and one end of the second connecting plate 433 away from the rotating plate 431 is hinged with a second clamping plate 435. The connection between the rotating plate 431 and the first connecting plate 432 is connected to the push-pull rod 41. A third clamping plate 4311 is formed at one end of the rotating plate 431 close to the first connecting plate 432, and a fourth clamping plate 4312 is formed at one end of the rotating plate 431 close to the second connecting plate 433.

[0037] Specifically, the middle of the rotating plate 431 is rotatably connected to the cover support plate 3, and the two ends are respectively hinged with the first clamping plate 434 and the second clamping plate 435 through the first connecting plate 432 and the second connecting plate 433, forming a four-bar linkage. When the push-pull rod 41 pulls the rotating plate 431, the rotating plate rotates around the hinge point, driving the first clamping plate 434 and the second clamping plate 435 to open and close through the connecting plates.

[0038] Open state: The clamping plates are open, allowing the cover to fall from the blanking hole 31 of the cover support plate 3 above the vacuum suction cup 5.

[0039] Closed state: The clamping plates clamp the penultimate layer of covers, preventing the upper covers from falling due to gravity or adhesion, ensuring that only a single cover contacts the vacuum suction cup each time.

[0040] The third clamping plate 4311 and the fourth clamping plate 4312 at both ends of the rotating plate 431 are arc-shaped plates, which match the edge contour of the cover. When the clamping plates open and close, they can perform radial limiting on the falling cover to avoid deviation.

[0041] Among them, the first clamping plate 434, the second clamping plate 435, the third clamping plate 4311 and the fourth clamping plate 4312 all adopt arc-shaped plate designs. The arc-shaped clamping plates can clamp the cover more evenly, avoiding local pressure concentration caused by flat contact during the clamping process, reducing the risk of cover damage and misalignment, and reducing friction through arc surface sliding during separation to improve the smoothness of the action.

[0042] As Figure 1 and Figure 2 shown, the blanking component 2 includes a material blocking rod 201. The lower end of the material blocking rod 201 is connected to the table board 1. A blanking channel 202 is formed between multiple material blocking rods 201; the blanking channel 202 surrounded by the material blocking rods 201 restricts the stacking direction of the covers to ensure that the covers fall vertically.

[0043] As Figure 2 and Figure 5As shown, a plurality of material discharging holes 31 are formed in the cover support plate 3, and the material discharging holes 31 are located between the material placing assembly 2 and the vacuum suction cup 5; the material discharging holes 3 of the cover support plate 3 are aligned with the position of the vacuum suction cup 5, guiding the cover to accurately fall to the adsorption area and reducing the position deviation.

[0044] As Figure 8 and Figure 9 shown, the flipping assembly 6 includes a mounting plate 61. The surface of the mounting plate 61 is connected to a plurality of vacuum suction cups 5. Both ends of the mounting plate 61 are connected to a flipping shaft 62. One end of the flipping shaft 62 is connected to a transmission cam 63 through a transmission shaft 64. A guide plate 65 is arranged on one side of the limit support plate 73, and a flipping chute 66 is formed in the guide plate 65. The transmission shaft 64 moves in the flipping chute 66.

[0045] By the operation of the lifting member 71, the mounting plate 61, the flipping shaft 62, the transmission cam 63 and the transmission shaft 64 are driven to descend. The transmission shaft 64 moves along a preset track in the flipping chute 66, which can drive the transmission cam 63 to rotate, and then drive the flipping shaft 62 and the mounting plate 61 to flip, so as to flip and cover the cover adsorbed by the vacuum suction cup 5.

[0046] Among them, the flipping chute 66 includes an upper arc-shaped slideway 661 and a lower arc-shaped slideway 662. The upper arc-shaped slideway 661 and the lower arc-shaped slideway 662 are such that when the transmission shaft 64 moves from the top to the bottom of the flipping chute 66, a 180° flip can be realized, and when the transmission shaft 64 moves from the bottom to the top of the flipping chute 66, a 180° flip can also be realized.

[0047] As Figure 1 and Figure 7 shown, the lifting assembly 7 includes a lifting member 71. The lower end of the lifting member 71 is connected with a lifting sleeve 72. The lifting sleeve 72 is sleeved outside the flipping shaft 62. Limiting support plates 73 are arranged on both sides of the lifting sleeve 72; by the operation of the lifting member 71, the lifting sleeve 72 and the flipping assembly 6 can be driven to lift, and the height of the vacuum suction cup 5 and the cover adsorbed by it can be adjusted, which is convenient for covering and placing products of different specifications and enhances the applicability of the mechanism.

[0048] Among them, the lifting member 71 can be a lifting cylinder or an electric lifting rod.

[0049] As Figure 6 and Figure 7As shown, a limiting rod 8 is installed on the limiting support plate 73. A first limiting plate 9 is rotatably connected to the limiting rod 8. The first limiting plate 9 is hinged to the second limiting plate 10. The second limiting plate 10 is connected to the turning shaft 62 through a limiting sleeve 11. A limiting rod 8 is installed on the limiting support plate 73. The limiting rod 8 is connected to the first limiting plate 9 and the second limiting plate 10 in a hinged manner, which limits the movement range of the turning assembly 6, ensures that the cover body can strictly follow the predetermined path during the turning process, thus avoiding the problems of dislocation and unstable operation of the cover body during the turning process, and further improving the operation accuracy.
