The bottom end of the output shaft of the second motor 7 is coaxially fixedly connected to a shaft, and the bottom end of the connecting shaft is coaxially fixedly connected to the glue-spinning disc 8, which matches the inner hole of the part.

[0030] A glue injection tube 9 is fixedly mounted on the slider 6, with the opening of the tube 9 facing the top end face of the glue-spinning disc 8. The glue injection tube 9 is connected to an external glue injection system. It should be noted that the glue injection system refers to the system that transports the glue liquid; this is existing technology and will not be described in detail here.

[0031] A pusher turntable 22 is rotatably mounted on the top of the base 1. The pusher turntable 22 is a horizontal disc. Multiple slots are formed on the circumferential end of the pusher turntable 22. These slots are used to engage parts and are compatible with the parts. The multiple slots are evenly distributed along the circumference of the pusher turntable 22. The revolution circumference of the slots intersects the downward extension line of the central axis of the connecting shaft.

[0032] A baffle 23 is fixedly installed on the top of the base 1. The baffle 23 is an arc-shaped plate. The baffle 23 is sleeved on the outside of the pusher turntable 22 and together with the pusher turntable 22 forms the same structure as the arc-shaped baffle and the glue injection turntable in the vacuum adsorption type glue injection turntable device described in announcement number CN216857223U.

[0033] A transmission chamber is provided inside the base 1, and a transmission mechanism is installed inside the transmission chamber. The transmission mechanism is used to drive the pusher turntable 22 to rotate intermittently. The pusher turntable 22 is connected to the slider 6 through the transmission mechanism.

[0034] Specifically, the transmission mechanism includes a first rotating shaft 12, a second rotating shaft 17, a third rotating shaft 21, a first transmission component, and a second transmission component.

[0035] A mounting block 11 is fixedly installed on the top inner wall of the transmission compartment. A first rotating shaft 12 passes through the mounting block 11 in a horizontal direction and is rotatably connected to the mounting block 11. The first rotating shaft 12 is driven to rotate by the slider 6 through a first transmission assembly.

[0036] Specifically, the first transmission assembly includes a rack 10 and a gear 14. The rack 10 is fixed vertically to the bottom of the slider 6, and the rack 10 is provided with a toothed section and a smooth section, with the toothed section located below the smooth section.

[0039] Specifically, the second transmission assembly includes a first bevel gear 15 and a second bevel gear 16. The first bevel gear 15 is fixedly sleeved on the first rotating shaft 12, and the second bevel gear 16 is fixedly sleeved on the second rotating shaft 17. The first bevel gear 15 and the second bevel gear 16 mesh with each other. In this embodiment, the transmission ratio between the first bevel gear 15 and the second bevel gear 16 is less than one.

[0040] The third rotating shaft 21 is vertically placed inside the transmission chamber, and its top and bottom ends are rotatably connected to the base 1. The top end of the third rotating shaft 21 extends out of the base 1 and is coaxially fixed to the pusher turntable 22. The third rotating shaft 21 is driven by the second rotating shaft 17 through a third transmission assembly. The third transmission assembly is used to drive the third rotating shaft 21 to rotate intermittently at a certain arc. The specific arc is optimized according to production needs and is existing technology, so it will not be described in detail here.

[0041] Specifically, the third transmission assembly includes a Geneva wheel 20 and a drive dial 18. The Geneva wheel 20 is fixedly mounted on the third rotating shaft 21, and the drive dial 18 is fixedly mounted on the second rotating shaft 17. A horizontal transmission plate is fixedly mounted on the drive dial 18, and a pin 19 is fixedly mounted vertically at the bottom of the transmission plate. The pin 19 is parallel to the third rotating shaft 21, and the pin 19 matches the push groove on the Geneva wheel 20 and slides along the push groove after rotating into it. After rotating into the push groove, the pin 19 abuts against the Geneva wheel 20 for transmission engagement, and the pin 19 is used to drive the Geneva wheel 20 to rotate intermittently. The third rotating shaft 21, the Geneva wheel 20, the second rotating shaft 17, the drive dial 18, the transmission plate, and the pin 19 together form a Maltese mechanism.

[0042] In this embodiment, the active dial 18 is a fan-shaped disk, and the central axis of the circular pin 19 is located on the extension line of the radial line in the middle of the fan-shaped disk.

[0043] Working principle: When using this device to apply adhesive to the inner hole of a part, the part is placed between one end of the pusher turntable 22 and the baffle 23 using an existing conveying mechanism or manually. Then, the first motor 3 is started, and its output shaft rotates forward and backward, driving the threaded rod 4 to rotate forward and backward. The threaded rod 4 pushes the slider 6 to slide up and down, and the slider 6 drives the rack 10 to move up and down. As the rack 10 moves up and down, it drives the gear 14 to rotate forward and backward.

[0044] When rack 10 moves down, gear 14 drives one-way bearing 13 to rotate freely.

[0045] When rack 10 moves upward, gear 14 drives one-way bearing 13 to rotate, and one-way bearing 13 drives first shaft 12 to rotate. First shaft 12 drives first bevel gear 15 to rotate, and first bevel gear 15 drives second bevel gear 16 to rotate. Second bevel gear 16 drives second shaft 17 to rotate, and second shaft 17 drives drive dial 18 to rotate. Drive dial 18 slides out of the arc-shaped groove of grooved wheel 20, thereby releasing the limiting effect on grooved wheel 20. At the same time, drive dial 18 drives transmission plate, and transmission plate drives round pin 19 to revolve around second shaft 17 and revolve closer to the push groove on grooved wheel 20. It should be noted that, to ensure the stable rotation of first bevel gear 15 and second bevel gear 16, both axial ends of first shaft 12 and bottom end of second shaft 17 are rotatably connected to the inner wall of transmission compartment.

[0046] When the pin 19 rotates into the groove on the grooved wheel 20, the pin 19 pushes the grooved wheel 20 to rotate by a certain arc. When the grooved wheel 20 rotates, it drives the third rotating shaft 21 to rotate. The third rotating shaft 21 drives the pusher turntable 22 to rotate by a certain arc. The slot of the pusher turntable 22 pushes the part between the single plate 23 and the pusher turntable 22 and gradually moves it directly below the glue-spraying disc 8.

[0047] Repeat the above steps until the first part is directly below the glue-spinning disc 8. At this point, the slider 6 moves down, causing the second motor 7 to move down as well. The output shaft of the second motor 7 drives the connecting shaft down, which in turn drives the glue-spinning disc 8 down into the inner hole of the part. Then, the second motor 7 is started, and its output drives the connecting shaft to rotate. The connecting shaft then drives the glue-spinning disc 8 to rotate, and the glue-spinning disc 8 sprays the glue flowing from the glue tube 9 onto the inner wall of the part's inner hole.

[0048] After the glue-spinning operation is completed, the second motor 7 is shut down. At this time, the slider 6 moves upward, and the glue-spinning disc 8 moves upward and out of the inner hole of the part. During this process, the slider 6 drives the rack 10 to move upward, and the rack 10 drives the toothed section to move upward and approach the gear 14 and finally mesh with the gear 14. It should be noted that when the toothed section of the rack 10 meshes with the gear 14, the glue-spinning disc 8 has already moved out of the inner hole of the part. Then, the pusher turntable 22 rotates a certain arc and pushes the next part to move directly below the glue-spinning disc 8. Thereafter, the above process is repeated, continuously spinning glue into the inner hole of subsequent parts.

[0049] It should be noted that the opening and closing of the second motor 7 and the first motor 3 can be controlled manually, by a sensor and controller, or by a micro switch and controller. All of these are existing mature technologies and will not be elaborated here.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
