[0001] This invention relates to the field of feeding and assembly technology, specifically to an automatic feeding and assembly machine for lip gloss fuzz. Background Technology

[0002] With the booming development of the cosmetics industry, consumers are increasingly demanding higher quality, production efficiency, and hygiene and safety standards for beauty products such as lip gloss. Lip gloss products are usually precisely assembled from two parts: a brush head and a brush handle. The quality of this assembly directly affects the product's feel, sealing performance, and appearance.

[0003] Traditional lip gloss brush head assembly mainly relies on manual operation or semi-automated equipment. However, manual insertion is slow and has poor assembly accuracy. Although some automated equipment has been applied to lip gloss brush head assembly, such as vibratory feeder feeding, robotic arm gripping, and pneumatic pressing, the connection between each process is not smooth, the degree of automation is incomplete, and it is impossible to achieve closed-loop control of the entire process from feeding to finished product. This makes it difficult to meet the needs of large-volume, high-precision production and also cannot quickly adapt to the production switch of different product specifications, resulting in the industry pain point of insufficient flexible production capacity.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: As Figure 1 - Figure 11 The illustrated automatic feeding and assembly machine for lip gloss tufts includes a frame 1 that serves as the basic support for the entire equipment. The frame 1 is equipped with two rotatable carriers, a first carrier 2 and a second carrier 3. The first carrier 2 is a small turntable specifically for feeding tufts. The tufts are arranged in an orderly manner and fed into the workstation of the first carrier 2 via a vibrating feeder or other feeding device. They then rotate with the turntable to the picking position. For details, refer to... Figure 5The carrier 2 3 includes a large turntable 301 and a secondary turntable 302. A spacer ring 303 is provided between the large turntable 301 and the secondary turntable 302 for spacing and fixation. The carrier 2 3 is used for feeding brush rods. The brush rods are fed into the station of the large turntable 301 and rotate with the drive. The secondary turntable 302 and its components form an independent positioning platform corresponding to the brush rod station. A direct vibration feeding brush rod mechanism 17 and a flipping brush rod mechanism 18 are fixedly installed on the frame 1 on one side of the carrier 2 3. The direct vibration feeding brush rod mechanism 17 feeds the brush rods one by one, and the flipping brush rod mechanism 18 moves the brush rods. For state correction, a vision inspection mechanism 23 is installed on the frame 1 below the brush rod flipping mechanism 18. During the flipping process, it is used to detect whether the brush rod exists, whether the direction is correct, and whether there are any defects. A transfer mechanism 19 is fixedly installed on the frame 1 on the side of the flipping brush rod mechanism 18 near the carrier 2 3. Qualified brush rods are sent into the large turntable 301 station of the carrier 2 3. A Delta robot vision feeding mechanism 20 is set on the frame 1 on the side of the carrier 1 2 for flexibly grasping the brush head. A brush head flipping mechanism 24 is set between the Delta robot vision feeding mechanism 20 and the carrier 1 2.

[0023] Reference Figure 3 The tip-turning mechanism 24 consists of a lifting cylinder 241, a connecting block 242, a rotating plate 243, a clamping cylinder 244, a sliding block 245, and a track plate 246. Specifically, as shown in... Figure 3 As shown, the lifting cylinder 241 is located in front of the Delta robot vision feeding mechanism 20. The movable part of the lifting cylinder 241 is fixedly connected to the connecting block 242. The connecting block 242 has a through hole, and the rotating plate 243 passes through the through hole and can rotate freely. One end of the rotating plate 243 is fixed to the clamping cylinder 244, which is used to clamp the rough material conveyed by the Delta robot vision feeding mechanism 20. The other end of the rotating plate 243 is connected to the sliding block 245. The sliding block 245 has a protrusion on the side away from the rotating plate 243. The track plate 246 has a corresponding "7"-shaped track, and the protrusion can slide along the track.

[0024] In actual operation, after the clamping cylinder 244 grips the rough material, the lifting cylinder 241 drives the connecting block 242 to move down. At this time, the protrusion of the sliding block 245 slides along the track, causing the sliding block 245 to rotate synchronously. Then, the rotating plate 243 drives the clamping cylinder 244 to rotate, and finally the rough material is accurately placed on the work position of the carrier 2 for subsequent processing. The flipping mechanism 24 can not only efficiently complete the flipping and precise transfer of rough materials, but also has excellent adaptability and flexibility: for rough materials of different specifications, such as size differences and changes in shape characteristics, the track plate 246 with different curvatures can be replaced or the track path parameters can be adjusted. With the precise adjustment of parameters such as the stroke of the lifting cylinder 241 and the clamping force of the clamping cylinder 244, the stable gripping and flipping action of various materials can be adapted. This modular adjustment design can quickly respond to the change of production needs without replacing the entire mechanism, which greatly shortens the changeover time when producing multiple types of materials. It not only improves the versatility of the equipment, but also reduces the equipment modification cost caused by changes in material specifications.

[0025] A flexible brush tip feeding system 21 is located on the side of the Delta robot's vision feeding mechanism 20 away from the carrier 2. The flexible brush tip feeding system 21 and the direct vibration feeding brush rod mechanism 17 are located on the same side. A support frame 4 is fixedly installed on the frame 1 between the carrier 2 and the carrier 3. A brush tip end oiling mechanism 22 is fixedly installed on the support frame 4 to automatically apply oil to the brush tip end for lubrication. A flattening mechanism 30 is fixedly installed on the frame 1 between the carrier 2 and the carrier 3 to flatten the surface of the brush rod and the brush tip. It also includes a brush rod and brush tip pressing mechanism 25, a brush rod heating mechanism 26, a dotting mechanism 27, and a pulling mechanism arranged clockwise along the outside of the carrier 3. In this embodiment, the brush rod bristle clamping mechanism 25 aligns the oiled bristles with the brush rod and applies pressure to complete the initial pressing and fixing. The brush rod heating mechanism 26 accelerates the softening of the brush rod, making the originally brittle brush rod less prone to cracking. The dotting mechanism 27 fixes the brush rod and bristles together again, causing the brush rod to deform slightly in dots to form a mechanical snap, enhancing the connection strength. The tensile testing mechanism 28 applies tensile force to the assembled product to detect whether the bonding strength between the bristles and the brush rod meets the standard, realizing online quality control. Finally, the finished product unloading mechanism 29 automatically removes the qualified products that have passed the test and collects them in categories.

[0026] Example 2: The automatic feeding and assembly machine for lip gloss fuzz provided in Example 1 has been further optimized, with reference to... Figure 1 - Figure 11The support frame 4 is equipped with a clamping assembly 5, which can move along the X and Z axes. It also includes a support base 8 fixedly mounted on the carrier 3. The support base 8 is fixedly mounted on the sub-disc 302. A positioning assembly 9 is slidably mounted on the support base 8. L-shaped connecting rods 10 are rotatably mounted on both sides of the support base 8. The turning point of the L-shaped connecting rod 10 is the pivot point. A slot 110 is formed on the L-shaped connecting rod 10. Sliding pins 11 adapted to the slot 110 are fixedly mounted on both sides of the positioning assembly 9. The sliding pins 11 on the positioning assembly 9 pass through the slot 110 on the L-shaped connecting rod 10 and slide with it, converting the swing of the L-shaped connecting rod 10 into... The linear sliding of the positioning component 9 should be noted. A return spring is provided between the positioning component 9 and the support base 8 to automatically reset the positioning component 9 after the linkage is released. A pressure rod 12 is fixedly installed on the clamping component 5. When the clamping component 5 picks up the brush head from the carrier 2 and moves towards the oiling mechanism 22 at the tip of the brush head, the brush head is dipped in a certain amount of lubricating oil. Subsequently, when the clamping component 5 moves with the oiled brush head above the positioning component 9, the pressure rod 12 is collinear with the L-shaped connecting rod 10. Its movement synchronously drives the positioning component 9 to clamp, position and reinforce the brush rod located at the assembly station of the carrier 3, and accurately assemble the brush head with the brush rod.

[0027] Specifically, refer to Figure 4 and Figure 6 The clamping assembly 5 includes a material-grabbing upright plate 510 fixedly mounted on the support frame 4. A movable side plate 520 is slidably mounted on the material-grabbing upright plate 510. A first cylinder 530 is fixedly mounted on the movable side plate 520. A connecting plate 570 is fixedly mounted on the output end of the first cylinder 530. Therefore, the extension and retraction movement of the first cylinder 530 drives the connecting plate 570 to perform vertical, i.e., Z-axis, lifting and lowering movement. The pressure rod 12 is fixedly mounted on both sides of the connecting plate 570. In this embodiment, the pressure rod 12 is a rigid rod, and its length and position are precisely designed to ensure that when the movable side plate 520 is in the second cylinder 560... When the drive moves horizontally to above the positioning component 9 of the carrier 2 3, the pressure rod 12 can accurately and vertically press down the free end of the L-shaped connecting rod 10. It also includes a gripper 540, which is fixedly installed on the connecting plate 570. A slide rail 550 adapted to the moving side plate 520 is fixedly installed on the material picking plate 510. A second cylinder 560 is fixedly installed on one side of the material picking plate 510. The output end of the second cylinder 560 is fixed to the moving side plate 520. The extension and retraction movement of the second cylinder 560 directly drives the moving side plate 520 to reciprocate linearly along the slide rail 550 to achieve horizontal sliding, i.e., sliding along the X-axis.

[0028] The gripper 540 includes a horizontal plate 541 fixed to the connecting plate 570. A fixed box 543 is mounted on the side of the horizontal plate 541 near the oil supply box 6 via a support rod 542. The fixed box 543 is hollow inside, and a third cylinder 544 is rotatably mounted inside the fixed box 543, with its output end extending from one side of the fixed box 543. A sleeve 545 is rotatably mounted on the side of the fixed box 543 near the oil supply box 6, with the axis of the sleeve 545 coinciding with the axis of the third cylinder 544. A rotating... The sleeve 545 is equipped with gripper 546, preferably two to four, which are symmetrically hinged on the outer circumference of the sleeve 545. When closed, they form a clamping cavity for gripping the brush head. The output end of the third cylinder 544 extends into the sleeve 545 and is fixedly installed with a circular block 547. The gripper 546 is rotatably connected to the circular block 547. When the third cylinder 544 drives the circular block 547 to move up and down, it will push or pull the end of the gripper 546, thereby realizing the opening and closing action of the gripper 546.

[0029] A motor 548 is fixedly installed on the horizontal plate 541. The output end of the motor 548 is connected to the third cylinder 544 through gear transmission. The function of the motor 548 is to drive the entire cylinder body of the third cylinder 544 to rotate around its axis.

[0030] Specifically, refer to Figure 4 and Figure 7 The oiling mechanism 22 at the tip of the brush includes an oiling box 6 containing oil and water. A rotatable oil wheel 7 is installed inside the oiling box 6, partially immersed in lubricating oil for picking up and transferring a measured amount of lubricating oil. A central shaft 13 is rotatably mounted inside the oiling box 6. The oil wheel 7 is fixedly mounted on the central shaft 13 via a key connection and rotates with the central shaft 13. Both ends of the central shaft 13 extend through the oiling box 6 and are fixedly mounted with swing arms 14. The swing arms 14 are rigid rods, their length direction perpendicular to the central shaft 13. A first torsion spring 15 is sleeved on the central shaft 13. Both ends of the first torsion spring 15 are fixedly connected to the outer wall of the oiling box 6 and the swing arms 14, respectively. Preferably, the first torsion springs 15 are symmetrically arranged, i.e., one is installed at each end of the central shaft 13 to ensure force balance. When the first torsion spring 15 is in a pre-tightened state, its elastic force tends to pull the swing arms 14 to a preset initial position.

[0031] The oil drum 7 has a groove 710 for quantitatively containing lubricating oil. When the oil drum 7 rotates, the groove 710 scoops a fixed volume of lubricating oil from the lubricating oil. The oil dispensing box 6 is equipped with a scraper 16. The position of the scraper 16 is fixed, and the cutting edge of the scraper 16 abuts against the outer circumferential surface of the oil drum 7 to scrape off excess lubricating oil adhering to the smooth surface of the oil drum 7, i.e., the area outside the groove 710. This ensures that only the lubricating oil in the groove 710 is effectively transferred, thereby ensuring the accuracy and consistency of the oil dispensing amount.

[0032] Specifically, refer to Figure 5 and Figure 8 - Figure 11 The positioning component 9 includes a positioning block 910 slidably mounted on the support base 8, with its sliding direction perpendicular to the axis of the brush rod. Symmetrically arranged positioning arms 920 are mounted on the side of the positioning block 910 near the oil dispenser 6, with the clamping surfaces of the two positioning arms 920 facing each other. Each of the two positioning arms 920 has a receiving groove 921, and an inclined plate 930 is provided within the receiving groove 921. A roller 940 is mounted on the end of the inclined plate 930 outside the receiving groove 921 via an elastic element. The outer circumferential surface of the roller 940 is used to contact the outer wall of the brush rod. The elastic element is preferably a compression spring 941, providing a preload force to press the roller 940 inward against the brush rod. The groove of the receiving groove 921... A support pin 950 is fixedly installed on the inner bottom surface, and an inclined plate 930 is rotatably installed on the support pin 950. A constraint groove 922 is opened on the inner side of the receiving groove 921. A constraint rod 931 adapted to the constraint groove 922 is fixedly installed on the inclined plate 930. A second torsion spring 960 is sleeved on the support pin 950. The two ends of the second torsion spring 960 are fixed to the inner bottom surface of the receiving groove 921 and the inclined plate 930, respectively. Furthermore, guide half grooves are opened on the opposite sides of the positioning arm 920. When the two positioning arms 920 are closed, the two guide half grooves are combined to form a guide groove 923 for the insertion of the burr. The assembly with the rod body forms circumferential constraint and precise guiding positioning.

[0033] Working principle: 1. Feeding and straightening; Carrier 1 2 receives the brush heads arranged in an orderly manner by feeding devices such as vibrating plate and rotates them to the preset picking position. Carrier 2 3 receives the brush rod and rotates it to the assembly position. Support 8 and positioning component 9 correspond to the assembly position. At this time, positioning block 910 is located outside the rod body under the action of return spring, waiting to be clamped. The second cylinder 560 extends, driving the movable side plate 520 to move horizontally along the slide rail 550, moving the gripper 540 directly above the material handling station of the carrier 2. The first cylinder 530 extends, driving the connecting plate 570 and the gripper 540 to descend vertically. The third cylinder 544 actuates, driving the circular block 547 to move, closing the gripper 546 and firmly grasping the burr. The second cylinder 560 drives the movable side plate 520 to carry the burr horizontally towards the oiling box 6, where the pressure rod 12 will contact... And push the swing arm 14, the swing arm 14 overcomes the elastic force of the first torsion spring 15 and swings, driving the oil wheel 7 to rotate through the central shaft 13. As the oil wheel 7 rotates, its groove 710 scoops a metered amount of lubricating oil from the oil. The oil wheel 7 continues to rotate, turning the groove 710 with the metered amount of lubricating oil to the oiling position. At the same time, the motor 548 starts and drives the cylinder body of the third cylinder 544 to rotate through gear transmission, so that the circumference of the hair head is in the groove 710 area of ​​the oil wheel 7, completing the transfer of the metered amount of lubricating oil. II. Oiling and Assembly; The second cylinder 560 continues to operate, driving the moving side plate 520 to move the oiled brush head to the assembly position directly above the carrier 2 3. The first cylinder 530 drives the connecting plate 570 to descend. The pressure rod 12 fixed on the connecting plate 570 first contacts the L-shaped connecting rod 10. The L-shaped connecting rod 10 rotates around its fulcrum. The strip groove 110 on the L-shaped connecting rod 10 pushes the sliding pin 11, thereby driving the positioning block 910 to overcome the elastic force of the return spring and slide to one side of the rod body. The roller 940 on the positioning arm 920 first contacts the outer wall of the brush rod. Under the abutment of the rod body, the roller 940, together with the inclined plate 930, compresses the second torsion spring 960 to achieve flexible self-adaptation. The brush head enters the guide half grooves on both sides to form the guide groove 923, which precisely constrains the brush rod. The first cylinder 530 continues to drive the connecting plate 570 to descend, precisely inserting the vertical brush head into the guide groove 923 and completing the coaxial docking assembly with the brush rod. III. Fixing and Inspection: After assembly, the product rotates with the carrier 2 3 and is successively pressed by the brush rod bristle pressing mechanism 25, stabilized by the brush rod heating mechanism 26, mechanically prevented from falling off by the dotting mechanism 27, and inspected by the tensile testing mechanism 28. Qualified products are collected by the finished product unloading mechanism 29, completing the fully automated production process.

[0034] Finally, carrier 1 (2) and carrier 2 (3) continue to rotate in an orderly manner, sending the next bristle head and brush rod into the work station, and the equipment enters the next work cycle.
