[0052] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0053] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0054] Figures 1-6 A quantitative dispensing device for plastic cup lids provided in this embodiment of the utility model includes:

[0055] The operating table 1 has multiple strip-shaped channels 2 arranged in parallel along the front-to-back direction at its upper end; multiple strip-shaped plates are arranged at intervals along the left-to-right direction at the upper end of the operating table 1, and the strip-shaped plates are arranged along the front-to-back direction, with the strip-shaped channels 2 formed between two adjacent strip-shaped plates.

[0056] The feeding mechanism is connected to the rear end of the strip channel 2 to continuously feed horizontally stacked plastic cup lids into the strip channel 2 from back to front.

[0057] The positioning detection mechanism is located above the operating table 1 and has multiple detection positions corresponding one-to-one with the strip groove 2 for detecting whether there is a plastic cup lid;

[0058] The lifting mechanism is provided with an installation groove on the bottom wall of the strip-shaped through groove 2, and the lifting mechanism is installed in the installation groove;

[0059] The separation and pushing mechanism is provided above each of the strip-shaped channels 2. The separation and pushing mechanism separates the multiple plastic cup lids at the frontmost side of the strip-shaped channels 2 from other plastic cup lids and pushes them forward to the lifting mechanism.

[0060] Packaging station 3;

[0061] A transfer mechanism is provided between the operating table 1 and the dispensing table 3 to transfer the plastic cup lid on the separation and pushing mechanism to the dispensing table 3.

[0062] In this embodiment, the processed plastic cup lids are conveyed to each strip-shaped channel 2 in a continuous horizontal stacking formation by the feeding mechanism, and the strip-shaped channel 2 guides the plastic cup lid column to move forward. Figure 2 As shown, once the foremost plastic cup lid moves forward to the detection position and is detected by the positioning detection mechanism, the separation and pushing mechanism begins to operate. Figure 3-4 As shown, it is in contact with a plastic cup lid that is currently in the separated position, such as Figure 5 As shown, the foremost plastic cup lids are pushed forward, separating them from the row of plastic cup lids and bringing them to the lifting mechanism, as... Figure 6 As shown, after being lifted by the lifting mechanism, the plastic cup lids enter the loading position of the transfer mechanism for easy clamping. Finally, the transfer mechanism moves the quantitative amount of plastic cup lids from the lifting mechanism to the dispensing table 3. After separation, the separation pushing mechanism returns to its initial position, the loading mechanism continues to convey the plastic cup lids forward, and the separation pushing mechanism waits for the next detection of the plastic cups by the positioning detection mechanism before performing the next separation. In this embodiment, the distance between the detection position of the positioning detection mechanism and the separation position of the separation pushing mechanism is constant, thereby ensuring that each separation can push the equal-length plastic cup lids forward, thus achieving quantitative separation of the plastic cup lids.

[0063] Preferably, in another embodiment of the present invention, the feeding mechanism includes:

[0064] Belt conveyor 4;

[0065] A limiting bracket 5 is disposed above the belt conveyor 4, and the limiting bracket 5 has a limiting groove that corresponds one-to-one with the strip through groove 2.

[0066] In this embodiment, a limiting bracket 5 is provided on the upper end of the belt conveyor 4. The limiting bracket 5 is provided with limiting grooves that correspond one-to-one with the strip through grooves 2. The limiting grooves are arranged in the front-back direction and are coaxially connected with the corresponding strip through grooves 2. The limiting grooves and the conveyor belt of the belt conveyor 4 form a conveying space that matches the plastic cup lid. The plastic cup lid is moved towards the operating table 1 by the conveyor belt. The limiting grooves ensure that the movement trajectory of the plastic cup lid is along the direction of the strip through groove 2.

[0067] Preferably, as another embodiment of the present invention, it further includes:

[0068] Mounting bracket 6 is mounted on the operating table 1, and all separation and pushing mechanisms are connected to the mounting bracket 6. The separation and pushing mechanism includes:

[0069] A linear drive unit 7 is mounted on the mounting bracket 6 in the front-to-back direction; the linear drive unit 7 may be a linear module with its slider facing downward and connected to the connecting seat 8.

[0070] A connecting seat 8 is disposed above the operating table 1 and is connected to the linear drive unit 7 in a transmission manner.

[0071] A lifting unit is mounted on the connecting seat 8;

[0072] Push plate 9 is vertically arranged and connected to the lifting unit.

[0073] In this embodiment, when the separation and pushing mechanism is not working, the connecting seat 8 is located at the rear limit position, and the pusher 9 is located above the strip groove 2. At this time, the area below the pusher 9 is the separation position. When the separation and pushing mechanism starts working, the lifting unit drives the pusher 9 to move downwards. The pusher 9 extends into the strip groove 2 and inserts into the gap between adjacent cup lids. The lower end contacts the plastic cup lid in the strip groove 2. Then, the linear drive unit 7 drives the connecting seat 8 to move forward. At this time, the pusher 9 moves forward accordingly and pushes the plastic cup lid located in front of it to separate from the row of plastic cup lids and move forward. After the linear drive unit 7 drives the connecting seat 8 to move forward to the front limit position, the lifting unit drives the pusher 9 to move upwards to above the strip groove 2. The linear drive unit 7 drives the connecting seat 8 to move backwards to the rear limit position, thus completing the quantitative separation of the plastic cup lids.

[0074] Specifically, the lifting unit includes:

[0075] The telescopic cylinder 22 has its cylinder body connected to the connecting seat 8, and its push rod is set vertically downward.

[0076] The L-shaped connecting plate 23 has one end connected to the push rod of the telescopic cylinder 22 and the other end connected to the push plate 9;

[0077] The slide rail 24 is vertically mounted on the connecting seat 8;

[0078] The slider 25 is mounted on the slide rail and is connected to the L-shaped connecting plate 23.

[0079] In this embodiment, the lifting unit, through the vertical extension and retraction of the telescopic cylinder 22, drives the L-shaped connecting plate 23 to move up and down, causing the lower end of the pusher 9 to extend between the two plastic cups below the separation position. The sliding rail limits the movement trajectory of the slider, making its lifting and lowering more stable.

[0080] Preferably, as another embodiment of this utility model, such as Figure 2-6 As shown, the positioning detection mechanism includes multiple sets of detection components, and the detection components include:

[0081] An infrared emitter 10 is mounted on the mounting bracket 6;

[0082] An infrared receiver 11 is provided with a mounting hole on the bottom wall of the strip-shaped through groove 2. The infrared receiver 11 is disposed in the mounting hole and is vertically opposite to the infrared transmitter 10. The detection position is formed between the infrared receiver 11 and the infrared transmitter 10.

[0083] In this embodiment, the infrared transmitter 10 emits infrared rays to the infrared receiver 11. When there is no plastic cup lid between them, the infrared receiver 11 receives the infrared rays emitted by the infrared transmitter 10. When the foremost plastic cup lid moves forward between them, the infrared rays between the infrared transmitter 10 and the infrared receiver 11 are interrupted, thereby forming a detection position between the infrared receiver 11 and the infrared transmitter 10.

[0084] Preferably, as another embodiment of this utility model, such as Figures 7-9 As shown, the lifting mechanism includes:

[0085] The lifting plate 12 is horizontally arranged in the mounting groove;

[0086] At least two lifting cylinders 13 are mounted on the operating table 1 via brackets, and the push rods of the lifting cylinders 13 are set upward and connected to the lifting plate 12;

[0087] The limiting rod 14 is vertically installed at the front end of the lifting plate 12.

[0088] In this embodiment, in the initial state, such as Figure 8As shown, the lifting plate 12 is located in the mounting groove, with its upper end flush with the upper end of the strip-shaped channel 2. The separation and pushing mechanism separates the foremost plastic cup lids in the strip-shaped channel 2 from the other plastic cup lids and pushes them forward onto the lifting plate 12. After the foremost plastic cup lids contact the limiting rod 14, the multiple plastic cup lids remain on the lifting plate 12. Then, the lifting cylinder 13 extends synchronously, lifting the lifting plate 12 upwards. Figure 9 As shown, this causes the plastic cup lid on the lifting plate 12 to move to the loading position of the transfer mechanism, and then the transfer mechanism transports it away. After the plastic cup lid is transported away, the lifting cylinder 13 retracts synchronously, and the lifting plate 12 returns to its initial position.

[0089] Preferably, in another embodiment of the present invention, the transfer mechanism includes:

[0090] A robotic arm is positioned between the operating table 1 and the dispensing table 3;

[0091] The clamping assembly 16 is connected to the robotic arm via a transmission.

[0092] In this embodiment, an existing robotic arm can be used, and will not be described in detail here. The robotic arm drives the gripping assembly 16 to move between the operating table 1 and the dispensing table 3, as follows: Figure 6 As shown, before the lifting mechanism lifts, the robotic arm drives the clamping assembly 16 to move above the strip channel 2, so that the loading position of the transfer mechanism is above the lifting mechanism.

[0093] Preferably, as another embodiment of this utility model, such as Figures 6-8 As shown, the clamping assembly 16 includes:

[0094] Connecting plate 17, the upper end of which is connected to the robotic arm;

[0095] Two vertical baffles 18 are both arranged at the lower end of the connecting plate 17 along the front-back direction, and a limiting cavity is formed between them;

[0096] Two clamping plates 19 are vertically arranged on both sides of the limiting cavity in the left-right direction, and the clamping plate 19 on the front side is provided with a notch corresponding to the limiting rod 14;

[0097] Two clamping cylinders 20 are disposed at the lower end of the connecting plate 17. The push rods of the two clamping cylinders 20 are horizontally arranged in the front-back direction and are respectively connected to the two clamping plates 19 to drive the two clamping plates 19 to move closer or further apart from each other.

[0098] The two clamping cylinders 20 extend and retract synchronously, and their push rods move in opposite directions. When the push rods of the two clamping cylinders 20 drive the two clamping plates 19...

[0099] In this embodiment, after the robotic arm moves the gripping assembly 16 above the strip-shaped through slot 2, as... Figure 8 As shown, the strip groove formed between the two vertical baffles 18 aligns with the strip through groove 2, forming a feeding position. The lifting cylinder 13 lifts the lifting plate 12 upwards, causing the plastic cup lid on the lifting plate 12 to move into the strip groove between the two vertical baffles 18. The two vertical baffles 18 continue to limit the plastic cup lid, and then the two clamping cylinders 20 drive the two clamping plates 19 to move closer together. The front clamping plate 19 passes through the notch to the limiting rod 14, as shown... Figure 9 As shown, the two clamping plates 19 clamp multiple plastic cup lids, thus completing the loading of the transfer mechanism. Then, the robotic arm moves the plastic cup lids to the dispensing table 3.

[0100] Preferably, in another embodiment of the present invention, the clamping assembly 16 further includes:

[0101] A horizontal baffle 21 is horizontally disposed in the limiting cavity and is connected to the two vertical baffles 18 respectively.

[0102] In this embodiment, when the lifting plate 12 moves the plastic cup lid upward to the loading position of the transfer mechanism, the plastic cup lid abuts against the horizontal baffle 21. The horizontal baffle 21 limits the plastic cup lid to prevent it from continuing to move upward under inertia after the lifting plate 12 stops rising, thus preventing the connection between the cup lids from becoming loose.

[0103] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
