Description

Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, and in particular to an adaptive feeding mechanism for a dispensing machine. Background Technology

[0002] A dispensing machine, also known as a glue applicator or glue dripper, is an automated machine that controls fluids and applies them to the surface or interior of a product by dripping, coating, or filling them. In order to improve dispensing efficiency, a feeding mechanism is used to automate the feeding process when using a dispensing machine.

[0003] A patent document with authorization announcement number CN210527819U discloses a high-precision dispensing machine feeding mechanism, including a base, a wall plate vertically mounted on the base, a fixed plate mounted on one side of the base, and an X-axis guide rail horizontally mounted on the side of the wall plate. An X-axis slider is movably connected to the X-axis guide rail, and the X-axis slider moves along the X-axis guide rail under the drive of a first driving component mounted on the fixed plate. A support plate is vertically mounted on the X-axis slider, and a Z-axis guide rail is vertically mounted on the side of the support plate. A Z-axis slider is movably connected to the Z-axis guide rail, and a feeding component for inductor feeding is mounted on the Z-axis slider. This patent document utilizes a servo motor, X-axis guide rail, and lead screw to achieve horizontal movement of the feeding component, improving stroke and accuracy. The device operates more smoothly and without impact, effectively improving work efficiency while ensuring a high yield rate.

[0004] The above-mentioned and existing technologies have the following drawbacks: Most existing feeding assemblies use a fixed assembly structure for their suction cups. In actual production, the workpieces to be glued often have irregular surfaces, making it difficult for the suction cup to adjust its adsorption position according to the actual surface shape of the workpiece. This easily leads to the suction cup adsorbing onto irregular areas of the workpiece, failing to form effective vacuum adsorption, and consequently causing the workpiece to fall off and feeding failure.

[0005] Therefore, an adaptive feeding mechanism for a dispensing machine is proposed. Utility Model Content

Therefore, an adaptive feeding mechanism for dispensing machines is proposed.

[0019] Preferably, the circumferential surface of the limiting rod is fixedly fitted with a buffer sleeve.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] like Figures 1-4 As shown, this utility model provides an adaptive feeding mechanism for a dispensing machine, including a mounting base 1. A servo motor 2 is fixedly mounted on the surface of the mounting base 1. A square tube 3 is fixedly mounted on the output end of the servo motor 2. A vertical plate 4 is fixedly mounted on one end of the square tube 3. A first electric push rod 5 is fixedly mounted on the surface of the vertical plate 4. A connecting plate 6 is fixedly mounted on the output end of the first electric push rod 5. Two through holes 7 are opened on the surface of the connecting plate 6. A sliding plate 8 is slidably connected to the inner wall of the through holes 7. An air suction pipe 9 is fixedly mounted inside the sliding plate 8. The lower end of the air suction pipe 9 is fixedly connected to a suction cup 10. The surface of the connecting plate 6 is fixedly mounted with... There is a second electric push rod 11, the output end of which is fixedly connected to the slide plate 8. A controller 18 is fixedly mounted on the surface of the vertical plate 4. The servo motor 2, the first electric push rod 5, and the second electric push rod 11 are all electrically connected to the controller 18. By setting a movable suction cup 10, when loading the workpiece to be glued, the horizontal distance and relative position of the two suction cups 10 can be adjusted so that the suction cups 10 avoid irregular areas, accurately adhere to the effective adsorption surface of the workpiece, adapt to workpieces with irregular surfaces, ensure effective vacuum adsorption, avoid workpiece falling off and loading failure, and improve loading efficiency and success rate.

[0029] like Figures 2-4 As shown, the vertical cross-section of the slide plate 8 is in the shape of an "I". The slide plate 8 is slidably connected to the connecting plate 6. The "I" shaped slide plate 8 can support the suction pipe 9 and suction cup 10 with the help of the connecting plate 6. The surface of the vertical plate 4 is fixedly equipped with a guide plate 12, which is slidably connected to the connecting plate 6. The guide plate 12 can guide the connecting plate 6, making the connecting plate 6 more stable when sliding. The surface of the guide plate 12 is fixedly equipped with two positioning blocks 13, and the connecting plate 6 is located between the two positioning blocks 13. The positioning blocks 13 can limit the stroke of the connecting plate 6 and prevent the connecting plate 6 from falling off the surface of the guide plate 12.

[0030] like Figures 3-4As shown, a fixing ring 14 is fixedly mounted on the surface of the mounting base 1, and an extension plate 15 is fixedly mounted on the surface of the square tube 3. The extension plate 15 is slidably connected to the fixing ring 14. By setting the fixing ring 14 and the extension plate 15, the square tube 3 can be supported by the cooperation of the extension plate 15 and the fixing ring 14, so that the square tube 3 can move stably. Two limiting rods 16 are fixedly mounted on the surface of the mounting base 1. The limiting rods 16 can limit the rotation range of the square tube 3 and ensure the smooth and accurate adjustment of the orientation. A buffer sleeve 17 is fixedly sleeved on the circumferential surface of the limiting rod 16. The buffer sleeve 17 can reduce the collision force between the square tube 3 and the limiting rod 16.

[0031] The overall working principle is as follows: When loading the workpiece to be glued, the controller 18 receives the loading command and drives the servo motor 2 to operate. The output of the servo motor 2 drives the square tube 3 to move, the square tube 3 drives the vertical plate 4 to move, the vertical plate 4 drives the first electric push rod 5 to move, the connecting plate 6 follows the first electric push rod 5 to drive the slider to move, and the suction pipe 9 follows the slider to drive the suction cup 10 to be adjusted above the workpiece to be glued. During this process, the square tube 3 is supported by the cooperation of the extension plate 15 and the fixing ring 14, so that the square tube 3 moves stably. At the same time, the rotation range of the square tube 3 is limited by the limit rod 16 to ensure that the orientation adjustment is smooth and accurate. The buffer sleeve 17 can reduce the collision force between the square tube 3 and the limit rod 16. Then the first electric push rod 5 is activated, pushing the connecting plate 6 to drive the suction cup 10 closer to the workpiece surface. The guide plate 12 can guide the connecting plate 6 to make the sliding of the connecting plate 6 more stable. The positioning block 13 can limit the stroke of the connecting plate 6 to prevent the connecting plate 6 from falling off the surface of the guide plate 12. When the position of suction cup 10 needs to be adjusted, controller 18 can drive the second electric push rod 11 to slide the slide plate 8, thereby adjusting the horizontal distance and relative position of the two suction cups 10, so that the suction cups 10 avoid irregular areas and accurately adhere to the effective adsorption surface of the workpiece. After the suction cup 10 reaches the preset position, the suction pipe 9 connects to the external vacuum negative pressure source to form stable adsorption and complete the material picking. Then, the output end of the first electric push rod 5 retracts, driving the workpiece to rise. The servo motor 2 transfers the workpiece to the top of the dispensing station. The first electric push rod 5 pushes the connecting plate 6 down again, and the suction cup 10 releases the negative pressure to achieve precise unloading, completing one loading process. In this process, by adaptively adjusting the adsorption position of the suction cup 10, it can adapt to workpieces with irregular surfaces, ensure effective vacuum adsorption, avoid workpiece falling off and loading failure, and improve loading efficiency and success rate.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
