Description

Technical Field

[0001] This utility model relates to the field of cosmetic production equipment technology, and in particular to a flexible precision feeding station, especially a flexible precision feeding station for lipstick tube processing. Background Technology

[0002] With the rapid development of the cosmetics industry, the market demand for makeup products such as lipsticks is increasing daily, while the requirements for production efficiency and automation levels are also rising. In modern lipstick production lines, automated equipment is widely used in processes such as filling, cooling, demolding, and packaging, significantly improving production efficiency. However, the automation level of the initial step in the production process—material tray loading—is relatively lagging behind, becoming a bottleneck restricting further improvement in the overall production line efficiency.

[0003] Currently, common automated feeding mechanisms for lipstick tube processing typically operate as follows: a tray containing lipstick tubes is placed at the feeding station, where a robotic arm or conveyor picks them up one by one for subsequent processing. However, this feeding method has a significant drawback: the tray has a limited capacity and requires manual initial placement and subsequent replacement.

[0004] At the start of production, operators need to manually move and precisely place the fully loaded trays onto the designated feeding device. Each tray has a limited capacity; once the material in a tray is used up, the operator must remove the empty tray and replace it with a new, fully loaded one. Due to the high frequency of tray replacements, the production line requires dedicated operators for continuous monitoring and control. This not only increases the labor intensity of workers but also necessitates a continuous human investment at this workstation, resulting in high labor costs. Simultaneously, management personnel also need to invest significant effort in supervision to ensure the timeliness and accuracy of the feeding process, preventing line downtime due to untimely feeding. This high reliance on manual labor makes it difficult for the lipstick tube production line to achieve the true goal of "one-time feeding, long-term automatic operation"—intelligent and unmanned production.

[0005] Therefore, the existing feeding mechanism for lipstick tube processing has problems such as incomplete automation, frequent manual intervention, limited production efficiency due to material change interruptions, and high labor costs. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by providing a flexible and precise feeding station. This flexible and precise feeding station can achieve large-capacity material storage and automatic material replenishment, thereby significantly extending the automatic running time after a single feeding. It also has a compact structure and high feeding accuracy.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flexible precision feeding station, comprising a frame, a lifting mechanism on the frame, the lifting mechanism including two vertically parallel first conveyor belts with opposing surfaces, each first conveyor belt having a plurality of support parts for supporting storage trays, the storage trays having placement slots for horizontal material placement; a placement platform; a collection mechanism including a lifting platform for receiving storage trays; a translation device including a first pushing part for pushing the storage trays on the support parts to the placement platform, and a second pushing part for pushing the storage trays on the placement platform to the lifting platform; an industrial camera mounted on the top of the placement platform to capture the material distribution position of the storage trays on the placement platform; and a first robotic arm equipped with... The system includes: a material-grabbing suction cup; a material-flipping mechanism comprising a transverse slide rail with a sliding seat driven by a first cylinder, a rotating shaft rotatably mounted on the sliding seat, a receiving seat mounted on the rotating shaft, a material-receiving suction cup mounted on the receiving seat, a guide rod bent and connected to one side of the rotating shaft, a fixing block with a bending guide groove, the guide rod inserted into the bending guide groove, and a circulating material conveying mechanism for conveying the cyclic movement of a mold base, the mold base having a positioning groove for vertical material positioning, the material-flipping mechanism flipping the material to enter the positioning groove; and a second robotic arm for gripping the material in the positioning groove and conveying it to subsequent processing equipment. The working process of this flexible precision feeding station is as follows: Workers place the material horizontally into the placement slot of the storage tray, then insert the tray into the support of the lifting mechanism. This completes the worker's operation. Because the lifting mechanism has multiple supports, it can handle large quantities of material feeding at once. The lifting mechanism raises the storage tray to a position where its bottom is flush with the placement platform. Then, a translation device moves the storage tray onto the placement platform. During this process, storage trays that have been unloaded from the placement platform are also moved to the collection mechanism for collection. On the placement platform, the material is controlled by a control device... The first robotic arm, in conjunction with an industrial camera, removes material from the storage tray and places it onto the receiving seat of the flipping material mechanism. Then, through the flipping mechanism, the material is placed vertically into the positioning slot on the mold base. The mold base is circulated and transported by a circulating material conveying mechanism. Finally, the second robotic arm picks up the material from the positioning slot and sends it to the subsequent processing equipment. This flexible precision feeding station can be applied to different lipstick tube processing equipment for precise feeding. It can achieve large-capacity material storage and automatic material replenishment, thereby significantly extending the automatic running time after a single feeding. It also has a compact structure and high feeding accuracy.

[0008] In the above technical solution, preferably, a backlit LED panel is provided at the bottom of the placement platform, and the storage tray is made of a light-transmitting material. The backlit LED panel emits light to illuminate the storage tray made of the light-transmitting material, making the areas with and without material clearly distinguishable in brightness and darkness. This allows for accurate shooting by the industrial camera, enabling precise judgment of the material's position and avoiding misoperation.

[0009] In the above technical solution, preferably, the storage tray includes a rigid outer disc body, and a soft material plate is disposed within the rigid outer disc body. The material plate has several horizontally arranged placement slots for horizontally placing materials. The rigid outer disc body is used to maintain the stable movement of the storage tray during the operation of the lifting mechanism, the translation device, and the collecting mechanism. The soft material plate prevents scratching the surface of the material during material placement and when the suction cup on the first robotic arm handles fine materials. Furthermore, the horizontal placement slots allow workers to easily place materials horizontally within the slots during loading, eliminating the need for individual insertion as required by vertical placement methods, effectively improving loading efficiency.

[0010] In the above technical solution, preferably, the collecting mechanism includes a vertical plate with a vertical slide rail. A lifting platform is slidably mounted on the vertical slide rail, and the lifting platform is driven to rise and fall by a ball screw driven by a motor. This collecting mechanism collects storage trays via a storage tray at the top of the lifting platform. During operation, after receiving a storage tray, the lifting platform lowers to its lowest position and then raises itself until the top surface of the storage tray is flush with the top surface of the platform.

[0011] In the above technical solution, preferably, the motor and the ball screw are driven by a belt.

[0012] In the above technical solution, preferably, the translation device includes a horizontally arranged support plate disposed on the top of the lifting mechanism. A rack and a first slide rail are arranged parallel to each other on the bottom surface of the support plate. A first plate driven by a second cylinder is slidably disposed on the first slide rail. A second slide rail parallel to the first slide rail is disposed at the bottom of the first plate. A second plate is slidably disposed on the second slide rail. Two synchronous pulleys are disposed on both sides of the first plate along the direction of the first slide rail. A synchronous belt is disposed on the two synchronous pulleys. A gear is connected to the synchronous pulley located on the rear side in the direction of travel. The gear meshes with the rack. A fixed arm is fixedly connected to the second plate. The fixed arm is fixedly connected to the synchronous belt. A first lifting cylinder and a second lifting cylinder are disposed at the bottom of both sides of the second plate along the direction of travel. The movable end of the first lifting cylinder is connected to the first pushing part, and the movable end of the second lifting cylinder is connected to the second pushing part. When this translation device is in operation, the first and second lifting cylinders extend first and second pushing parts extend to the rear of the storage tray on the lifting platform and the placement platform. Then, the second cylinder extends, pushing the first plate forward. During the forward push of the first plate, the gear and rack mesh, driving the synchronous belt pulley to rotate. As the synchronous belt pulley rotates, the synchronous belt rotates. Since the side of the synchronous belt that moves forward is fixedly connected to the second plate through the fixed arm, it drives the second plate to move further forward relative to the first plate, thus allowing the second plate to extend a longer distance. This completes the process of pushing the storage tray on the lifting platform to the placement platform, and then pushing the storage tray on the placement platform to the collection mechanism. Afterward, the first and second lifting cylinders reset, and the second cylinder resets, thus completing one translation operation of the storage tray. This translation device has a compact structure, a long pushing distance, and does not obstruct the field of view of the industrial camera on top of the placement platform after resetting.

[0013] In the above technical solution, preferably, the circulating material conveying mechanism includes two parallel first guide grooves, and a second conveyor belt rotating in opposite directions is provided at the bottom of the two first guide grooves. The mold base is provided in the first guide groove and is moved by the second conveyor belt. A switching mechanism for switching the mold base between the two first guide grooves is provided at both ends of the first guide grooves. The switching mechanism includes a second guide groove that connects the two first guide grooves, a third cylinder for pushing the mold base from one end of the second guide groove to the other end, and a fourth cylinder for pushing the mold base from the second guide groove to the second conveyor belt. The switching mechanisms at both ends drive the mold base to switch in opposite directions. In this circulating material conveying mechanism, multiple mold holders are arranged in the first guide groove and transported by the second conveyor belts rotating in opposite directions on both sides. When the mold holders are transported to the end of the second conveyor belt, they enter one end of the second guide groove of the switching mechanism. At this time, the mold holders are pushed from one end of the second guide groove to the other end by the third cylinder, and then the mold holders are pushed from the second guide groove to the second conveyor belt by the fourth cylinder, so that the mold holders can circulate within the two first guide grooves and two second guide grooves that form a ring.

[0014] In the above technical solution, preferably, the mold base includes a base and a positioning mold. The base is provided with a receiving groove, and the positioning mold is inserted into the receiving groove. The positioning mold is provided with the positioning groove. This structure allows for the adaptation to the positioning of different types of materials by changing the positioning mold, thus enabling it to be adapted to the processing of different lipstick tubes.

[0015] In the above technical solution, preferably, a first magnet is provided at the bottom of the receiving groove, and a second magnet is provided at the bottom of the positioning mold, with the first magnet and the second magnet magnetically engaging. This structure enables the positioning mold and the receiving groove to be magnetically positioned, making the positioning more reliable and facilitating assembly and disassembly.

[0016] In the above technical solution, preferably, a feeding detection sensor is installed on the frame at the feed inlet side of the lifting mechanism. The feeding detection sensor consists of an infrared transmitter and an infrared receiver located on the upper and lower sides of the feed inlet. When the infrared receiver does not receive infrared light emitted by the infrared transmitter, the lifting mechanism stops operating. This structure uses the infrared receiver to detect whether the infrared light emitted by the infrared transmitter is blocked, preventing the lifting mechanism from operating while workers are loading the storage tray into it from the feed inlet.

[0017] Compared with the prior art, this utility model has the following advantages: The working process of this flexible precision feeding station is as follows: the worker lays the material horizontally in the placement slot of the storage tray, and then inserts the storage tray into the support part of the lifting mechanism, thus completing the worker's operation. Since the lifting mechanism has multiple support parts, it can complete the feeding operation of a large amount of material at one time. The lifting mechanism lifts the storage tray to a position where the bottom is flush with the placement platform, and then moves the storage tray horizontally onto the placement platform through the translation device. During this process, the storage trays that have been unloaded from the placement platform are also moved horizontally onto the collection mechanism for collection. On the platform, under the control of the control device, the first robotic arm, in conjunction with an industrial camera, removes the material from the storage tray and places it on the receiving seat of the flipping material mechanism. Then, through the flipping of the material mechanism, the material is placed vertically in the positioning slot on the mold base. The mold base is circulated and transported by the circulating material conveying mechanism. Then, the second robotic arm picks up the material in the positioning slot and sends it to the subsequent processing equipment. This flexible precision feeding station can be applied to different lipstick tube processing equipment for precise feeding. It can achieve large-capacity material storage and automatic material replenishment, thereby significantly extending the automatic running time after a single feeding. It also has a compact structure and high feeding accuracy. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1 to 13A flexible precision feeding station includes a frame 1, on which a lifting mechanism 2 is mounted. The lifting mechanism 2 includes two vertically parallel first conveyor belts 3 with opposing surface surfaces. Each first conveyor belt 3 is provided with several support parts 5 for supporting a storage tray 4. The support parts 5 are bent plates fixed to the surface of the first conveyor belt 3 and rotate with the rotation of the first conveyor belt 3. One support part 5 on each of the two first conveyor belts 3 is used to jointly support one storage tray 4. The storage tray 4 is provided with a placement groove 6 for horizontal material placement. The placement groove 6 is multiple... A parallel long straight groove; a placement platform 7 for placing a storage tray 4 for the first robotic arm 14 to grasp the material in the storage tray 4; a collection mechanism 8 including a lifting platform 9 for receiving the storage tray 4; a translation device 10 including a first pushing part 11 for pushing the storage tray 4 on the support 5 to the placement platform 7, and a second pushing part 12 for pushing the storage tray 4 on the placement platform 7 to the lifting platform 9; an industrial camera 13, mounted on top of the placement platform 7 to capture images of the storage tray 4. The material distribution position of the storage tray 4 on platform 7; the first robotic arm 14, which is equipped with a material-picking suction cup 15; the material-turning mechanism 16, which includes a transverse slide rail 17, on which a sliding seat 19 driven by a first cylinder 18 is provided, a rotating shaft 20 is rotatably mounted on the sliding seat 19, a receiving seat 21 is mounted on the rotating shaft 20, a receiving suction cup 22 is mounted on the receiving seat 21, and a guide rod 23 is bent and connected to one side of the rotating shaft 20. The material-turning mechanism 16 also includes a fixing block 24. The 4 is provided with a bending guide groove 25, and a guide rod 23 is inserted into the bending guide groove 25. When the first cylinder 18 drives the sliding seat 19 to slide back and forth, the guide rod 23 slides in the bending guide groove 25 to drive the receiving seat 21 to rotate 90 degrees; a circulating material conveying mechanism 26 is used to convey the mold base 27 to move cyclically. The mold base 27 has a positioning groove 28 for vertical positioning of the material. The flipping material mechanism 16 flips the material to enter the positioning groove 28; and a second robot arm 29 is used to pick up the material in the positioning groove 28 and send it to the subsequent processing equipment.The working process of this flexible precision feeding station is as follows: the worker lays the material horizontally in the placement slot 6 of the storage tray 4, and then inserts the storage tray 4 into the support part 5 of the lifting mechanism 2, thus completing the worker's operation. Since the lifting mechanism 2 has multiple support parts 5, it can complete the feeding operation of a large amount of material at one time. The lifting mechanism 2 lifts the storage tray 4 to a position where the bottom is flush with the placement platform 7, and then moves the storage tray 4 onto the placement platform 7 through the translation device 10. During this process, the storage tray 4 that has been unloaded from the placement platform 7 is also moved to the collection mechanism 8 for collection. On the placement platform 7, the material is collected under the control of the control device. The first robotic arm, in cooperation with the industrial camera 13, removes the material from the storage tray 4 and places it on the receiving seat 21 of the flipping material mechanism 16. Then, through the flipping of the flipping material mechanism 16, the material is placed vertically in the positioning groove 28 on the mold base 27. The mold base 27 is circulated and transported by the circulating material conveying mechanism 26. Then, the second robotic arm 29 picks up the material in the positioning groove 28 and sends it to the subsequent processing equipment. This flexible precision feeding station can be applied to different lipstick tube processing equipment for precise feeding. It can achieve large-capacity material storage and automatic material replenishment, thereby significantly extending the automatic running time after a single feeding. It also has a compact structure and high feeding accuracy.

[0032] In this embodiment, a backlit LED panel is provided at the bottom of the placement platform 7, and the storage tray 4 is made of a light-transmitting material. The light emitted by the backlit LED panel illuminates the storage tray 4 made of light-transmitting material, making the areas with and without material clearly distinguishable in brightness and darkness. This allows the industrial camera 13 to capture images accurately, accurately determine the position of the material, and avoid misoperation.

[0033] In this embodiment, the storage tray 4 includes a rigid outer plate 30, and a soft material plate 31 is disposed inside the rigid outer plate 30. Several horizontal placement slots 6 for horizontally placing materials are arranged on the soft material plate 31. The rigid outer plate 30 is used to keep the storage tray 4 moving stably during the operation of the lifting mechanism 2, the translation device 10 and the collecting mechanism 8. The soft material plate 31 can prevent scratching the surface of the material during material feeding and when the material is picked up by the suction cup 15 on the first robotic arm. Furthermore, the horizontal placement slots 6 allow workers to easily place the material horizontally in the placement slots 6 during loading, without having to insert each piece into the slot one by one as with vertical placement, effectively improving loading efficiency.

[0034] In this embodiment, the collection mechanism 8 includes a vertical plate 32, on which a vertical slide rail 33 is provided. A lifting platform 9 is slidably mounted on the vertical slide rail 33. The lifting platform 9 is driven to rise and fall by a ball screw 35 driven by a motor 34. This collection mechanism 8 collects the storage tray 4 at the top of the lifting platform 9. During operation, after receiving a storage tray 4, the lifting platform 9 lowers to its lowest position and then raises the lifting platform 9 until the top surface of the storage tray 4 is flush with the top surface of the placement platform 7.

[0035] In this embodiment, the motor 34 and the ball screw 35 are driven by a belt.

[0036] In this embodiment, the translation device 10 includes a horizontally positioned support plate 36 disposed on the top of the lifting mechanism 2. A rack 37 and a first slide rail 38 are parallel to each other on the bottom surface of the support plate 36. A first flat plate 40 driven by a second cylinder 39 is slidably mounted on the first slide rail 38. A second slide rail 41 parallel to the first slide rail 38 is disposed at the bottom of the first flat plate 40. A second flat plate 42 is slidably mounted on the second slide rail 41. Two synchronous pulleys 43 are disposed on both sides of the first flat plate 40 along the direction of the first slide rail 38. A timing belt 44 is provided on the timing pulley 43. A gear 45 is connected to the timing pulley 43 located on the rear side in the direction of travel. The gear 45 meshes with the rack 37. A fixed arm 46 is fixedly connected to the second plate 42. The fixed arm 46 is fixedly connected to the timing belt 44. A first lifting cylinder 47 and a second lifting cylinder 48 are provided at the bottom of both sides of the second plate 42 in the direction of travel. The movable end of the first lifting cylinder 47 is connected to a first pushing part 11, and the movable end of the second lifting cylinder 48 is connected to a second pushing part 12. When this translation device 10 is in operation, firstly, the first lifting cylinder 47 and the second lifting cylinder 48 extend, and the first pushing part 11 and the second pushing part 12 extend to the rear side of the lifting platform 9 and the storage tray 4 on the placement platform 7. Then, the second cylinder 39 extends, pushing the first plate 40 forward. During the forward pushing of the first plate 40, the gear 45 meshes with the rack 37, driving the synchronous pulley 43 to rotate. During the rotation of the synchronous pulley 43, the synchronous belt 44 rotates. The side of the synchronous belt 44 that moves forward is fixedly connected to the second plate 42 through the fixed arm 46. Therefore, the second plate 42 is moved forward further relative to the first plate 40, so that the second plate 42 extends a longer distance, completing the pushing of the storage tray 4 on the lifting platform 9 onto the placement platform 7, and the pushing of the storage tray 4 on the placement platform 7 onto the collection mechanism 8. Then the first lifting cylinder 47 and the second lifting cylinder 48 are reset, and then the second cylinder 39 is reset, thus completing one translation operation of the storage tray 4. The translation device 10 has a compact structure, a long pushing distance, and will not obstruct the shooting field of the industrial camera 13 on the top of the placement platform 7 after reset.

[0037] In this embodiment, the circulating material conveying mechanism 26 includes two parallel first guide grooves 49. The bottom of the two first guide grooves 49 is provided with a second conveyor belt 50 that rotates in opposite directions. A mold base 27 that is driven to move by the second conveyor belt 50 is provided in the first guide groove 49. At both ends of the first guide groove 49, there are shifting mechanisms 51 for shifting the mold base 27 between the two first guide grooves 49. The shifting mechanism 51 includes a second guide groove 52 that connects the two first guide grooves 49, a third cylinder 53 for pushing the mold base 27 from one end of the second guide groove 52 to the other end, and a fourth cylinder 54 for pushing the mold base 27 from the second guide groove 52 to the second conveyor belt 50. The shifting mechanisms 51 at both ends drive the mold base 27 to shift in opposite directions. When this circulating material conveying mechanism 26 is working, multiple mold bases 27 are arranged in the first guide groove 49 and transported by the second conveyor belt 50 rotating in opposite directions on both sides. When the mold base 27 is transported to the end of the second conveyor belt 50, it enters one end of the second guide groove 52 of the switching mechanism 51. At this time, the mold base 27 is pushed from one end of the second guide groove 52 to the other end by the third cylinder 53, and then the mold base 27 is pushed from the second guide groove 52 to the second conveyor belt 50 by the fourth cylinder 54, so that the mold base 27 can circulate within the two first guide grooves 49 and the two second guide grooves 52 that form a ring.

[0038] In this embodiment, the mold base 27 includes a base 55 and a positioning mold 56. The base 55 is provided with a receiving groove 57, and the positioning mold 56 is inserted into the receiving groove 57. The positioning mold 56 is provided with a positioning groove 28. This structure allows for the adaptation of positioning for different types of materials by replacing the positioning mold 56, thus enabling it to be adapted to the processing of different lipstick tubes.

[0039] In this embodiment, a first magnet 58 is provided at the bottom of the receiving groove 57, and a second magnet 59 is provided at the bottom of the positioning mold 56. The first magnet 58 and the second magnet 59 are magnetically attracted to each other. This structure enables the positioning mold 56 and the receiving groove 57 to be magnetically positioned, making the positioning more reliable and facilitating assembly and disassembly.

[0040] In this embodiment, a feeding detection sensor 60 is installed on the frame 1 on the side of the feed inlet 61 of the lifting mechanism 2. The feeding detection sensor 60 consists of an infrared transmitter and an infrared receiver located on the upper and lower sides of the feed inlet 61. When the infrared receiver does not receive the infrared light emitted by the infrared transmitter, the lifting mechanism 2 stops operating. This structure uses the infrared receiver to detect whether the infrared light emitted by the infrared transmitter is blocked, thus preventing the lifting mechanism 2 from running when workers are loading the storage tray 4 into the lifting mechanism 2 from the feed inlet 61.

[0041] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
