Description

Technical Field

[0001] This utility model relates to the field of cosmetic production line technology, specifically an automatic positioning and installation mechanism for powder puffs. Background Technology

[0002] Setting powder is a commonly used product in the makeup process. Its packaging typically consists of a bottle, inner stopper, powder puff, and cap. The production process involves sequentially filling the bottle with powder, inserting the inner stopper, attaching the powder puff, and capping the bottle. The powder puff, as a makeup tool that comes into direct contact with the skin, is often designed with a ribbon attached to the upper side of the puff. The two ends of this ribbon connect to the puff, creating a space for the user to insert their fingers, making it convenient for holding and applying makeup.

[0003] In actual production, the outer side of the powder puff ribbon is usually printed with the brand logo to enhance product recognition. To ensure consistent user experience and brand image, the logo on the powder puff ribbon needs to be adjusted to be parallel and upright with the logo on the outside of the bottle during assembly. However, this adjustment is currently mostly done manually, requiring operators to manually rotate or flip the powder puff to align the logo. This manual adjustment method has the following problems: First, because the powder puff material is soft and easily deformed, and the ribbon position is fixed, the fine adjustment process is tedious and requires a high level of skill and concentration from the operator; second, manual operation is inefficient, making it difficult to meet the needs of large-scale production, and the high labor intensity can easily lead to worker fatigue; in addition, the consistency of manual adjustment is poor, and problems such as logo misalignment and tilting are prone to occur, affecting the product's appearance quality.

[0004] Therefore, the existing technology for adjusting the logo on the powder puff during the production of setting powder has drawbacks such as high labor intensity, low efficiency, and difficulty in ensuring consistency. An automated solution is urgently needed to optimize the production process. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses an automatic positioning and installation mechanism for powder puffs.

[0006] This utility model provides an automatic positioning and installation mechanism for powder puffs, including:

[0007] The conveyor transports the powder puffs from the tail end of the conveyor to the head end, near the conveyor belt of the assembly line;

[0008] The vision system, located above the beginning of the conveyor, is used to identify the ribbon on the powder puff closest to the production line and determine the orientation of the logo on the ribbon.

[0009] The gripper is used to grab the powder puff;

[0010] Adjust the motor to drive the gripper to rotate and adjust the orientation of the logo on the ribbon;

[0011] The transfer component drives the grippers to lift and move horizontally, transferring the powder puffs from the conveyor to the cosmetic cases on the assembly line conveyor belt.

[0012] Furthermore, the transfer assembly includes a horizontally arranged first linear slide, the drive end of which is mounted with a vertically arranged mounting plate;

[0013] A vertically arranged second linear slide is mounted on the mounting plate, and a fixed plate is mounted on its drive end.

[0014] A connector is mounted on the fixed plate;

[0015] An adjustment motor is fixedly installed at the upper end of the connector;

[0016] The lower side of the connector is provided with a pneumatic finger that is fixedly connected to the drive end of the adjustment motor;

[0017] The gripper is mounted on the drive end of the pneumatic finger.

[0018] Furthermore, a material storage assembly is provided on the upper side of the tail end of the conveyor;

[0019] The powder puffs are stacked one on top of the other inside the material storage component;

[0020] A gripping component is installed below the storage component to grip the powder puffs at the bottom of the storage component one by one and place them on the conveyor for transport.

[0021] Furthermore, the material storage assembly includes a discharge plate disposed on the upper side of the conveyor;

[0022] The feeding plate has feeding holes;

[0023] An upwardly extending feed cylinder is provided on the outside of the feed hole;

[0024] The powder puffs are stacked one on top of the other inside the feeding hopper.

[0025] Furthermore, the feeding cylinder is composed of 3-4 first connecting rods that are evenly distributed around the circumference and extend vertically.

[0026] Furthermore, the storage assembly also includes a retaining ring;

[0027] The first connecting rod is inserted into the fixed ring.

[0028] Furthermore, the inner side of the fixing ring is provided with an open, arc-shaped groove;

[0029] The first link is engaged in the slot.

[0030] Furthermore, a second link arranged in the same circumference is provided between the first link;

[0031] The second link is located below the fixed ring and has a gap between it and the fixed ring.

[0032] Furthermore, the upper end of the second link is provided with an inner chamfer.

[0033] Furthermore, the gripping components include a suction head and a cylinder that drives the suction head to rise and fall;

[0034] As the suction head rises, it picks up the powder puff at the bottom of the storage assembly.

[0035] As the suction head descends, the bottommost powder puff inside the storage assembly detaches from the storage assembly and falls onto the conveyor.

[0036] The beneficial effects of this utility model are:

[0037] 1. The vision system automatically identifies the orientation of the powder puff ribbon logo and uses an adjustable motor to drive the gripper for precise rotation. This eliminates problems such as logo misalignment or tilting caused by visual fatigue or skill differences during manual operation, ensuring that the logo on each powder puff remains parallel and upright with the logo on the outside of the cosmetic box. This significantly improves the product's appearance quality and the consistency of the brand image.

[0038] 2. The automated mechanism enables continuous conveying, identification, adjustment and installation of powder puffs. It can accurately position the logo orientation without manual intervention, overcoming the bottleneck of low efficiency of manual operation. It can meet the needs of large-scale assembly line production, significantly shorten the production cycle and improve the overall capacity.

[0039] 3. Replacing repetitive manual operations with automated equipment reduces reliance on operator skill and attention, lowers labor intensity, and reduces errors caused by fatigue, which helps save labor costs and improve the working environment. Attached Figure Description

[0046] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0047] like Figure 1 and Figure 2 As shown, this utility model discloses an automatic positioning and installation mechanism for powder puffs, which is vertically installed on one side of the conveyor belt of the assembly line. It includes a conveyor 1, which is equipped with two parallel, spaced, and synchronously moving conveyor belts 14. The upper side of the conveyor belts 14 moves from the tail end of the conveyor 1 to the head end, close to the conveyor belt of the assembly line.

[0048] A material storage assembly 11 is located directly above the tail end of conveyor 1, and powder puffs 2 are placed inside the material storage assembly 11 in a stacked manner. The specific structure of the material storage assembly 11 is as follows: Figure 4 As shown, the material storage assembly 11 includes a horizontally arranged feeding plate 111 positioned directly above the conveyor belt 14. The feeding plate 111 has a feeding hole 112, which allows the powder puff 2 to pass through. An upwardly extending feeding cylinder 113 is provided outside the feeding hole 112 and located directly above the feeding hole 112. The powder puff 2 is stacked vertically inside the feeding cylinder 113.

[0049] Since the powder puff 2 falls freely from the top of the feeding cylinder 113, its position may shift. Therefore, the feeding cylinder 113 is designed to consist of 3-4 vertically extending first connecting rods 114 evenly arranged around the circumference, with the lower ends of the first connecting rods 114 fixedly connected to the feeding plate 111. This design provides sufficient operating space for the hand to place the powder puff 2 between the first connecting rods 114, ensuring that the powder puff 2 is always supported by the hand during stacking, resulting in higher stacking accuracy. In this embodiment, four first connecting rods 114 are used because their positions not only form a circle but also a square, facilitating the marking and positioning of the first connecting rods 114.

[0050] The first connecting rod 114 extends upwards but is only fixed at its lower end, resulting in an unstable position. Therefore, a retaining ring 115 is provided above and near the feed plate 111, with the first connecting rod 114 inserted into it. The retaining ring 115's position near the feed plate 111 ensures higher positioning accuracy when the powder puff 2 falls; furthermore, the portion of the first connecting rod 114 above the retaining ring 115 is elastic, facilitating the placement of the powder puff 2. The retaining ring 115 has a threaded hole on its radially outer surface, with a set screw threadedly connected to it. The threaded end of the set screw abuts against the first connecting rod 114, securing the retaining ring 115. Moreover, the retaining ring 115 will not tilt due to the limiting effect of the first connecting rod 114.

[0051] During installation, the retaining ring 115 is first placed on the upper end of the first connecting rod 114, ensuring that each first connecting rod 114 is accurately inserted into the retaining ring 115. Then, the retaining ring 115 is driven downwards, resulting in significant friction during this downward movement. Therefore, the inner side of the retaining ring 115 is provided with an open, arc-shaped slot 116, into which the first connecting rod 114 is inserted. This slot 116 serves not only to limit the movement of the first connecting rod 114 but also to facilitate the downward movement of the retaining ring 115.

[0052] While the number of first connecting rods 114 facilitates the feeding of powder puff 2, the limited number of limiting points for powder puff 2 results in low positional accuracy during its descent. Therefore, a second connecting rod 117 extending upwards is provided at the center between adjacent first connecting rods 114, arranged circumferentially with the first connecting rods 114. The lower end of the second connecting rod 117 is also fixedly connected to the feeding plate 111, and the top of the second connecting rod 117 is located below the fixing ring 115, with a gap between them. The advantages of this arrangement are: 1. The second connecting rod 117 increases the limiting points for powder puff 2, resulting in higher positional accuracy for powder puff 2 located below the fixing ring 115; 2. The second connecting rod 117 is shorter, with less deformation at its upper end, and will not affect the positional accuracy of powder puff 2. Therefore, the second connecting rod 117 is not connected to the fixing ring 115, reducing the installation difficulty of the fixing ring 115.

[0053] To prevent the powder puff 2 from being blocked by the upper end of the second link 117, the upper end of the second link 117 is also provided with an inner chamfer 119, which not only allows the upper end of the second link 117 to avoid the powder puff 2, but also guides the powder puff 2 as it falls.

[0054] The lower end of the feeding hole 112 is provided with an inwardly protruding ring 118. The inner diameter of the ring 118 is smaller than the outer diameter of the powder puff 2, so that the powder puff 2 in the feeding cylinder 113 is stacked upward from the ring 118. Moreover, the inner diameter of the ring 118 is configured such that the powder puff 2 can fall downward from the ring 118 through external force deformation.

[0055] The conveyor belt 14 is also provided with baffles 15 on both sides. The baffles 15 block the powder puff 2, so that the powder puff 2 moves in a position on the conveyor belt 14.

[0056] A suction head 12 and a cylinder 13 located below the conveyor belt 14, driving the suction head 12 to rise and fall, are arranged between the conveyor belts 14. The suction head 12 can adsorb the lower end face of the powder puff 2 through its negative pressure. When the suction head 12 rises, it adsorbs and fixes the powder puff 2 at the bottom of the feeding cylinder 113; when the suction head 12 falls, the powder puff 2 deforms and detaches downward from the feeding plate 111, and the remaining powder puffs 2 fall freely and stack on the convex ring 118. When the suction head 12 falls below the conveyor belt 14, the powder puff 2 on the suction head 12 is supported by the conveyor belt 14, detaches from the suction head 12, and is conveyed with the conveyor belt 14. Therefore, the spacing of the conveyor belts 14 is set such that the supporting force of the conveyor belt 14 on the powder puff 2 is greater than the adsorption force of the suction head 12. With this setting, the suction head 12 is always in working condition, making operation more convenient. In another embodiment, the conveyor belt 14 only needs to be able to support the powder puff 2. When the powder puff 2 moves down and gets close to the conveyor belt 14, the negative pressure of the suction head 12 disappears, and it will not obstruct the powder puff 2 from being conveyed on the conveyor belt 14.

[0057] A gripper 4 is installed at the front end of conveyor 1 to grasp powder puffs 2; a transfer assembly is also provided to drive the gripper 4 to move up, down, and horizontally, transferring the powder puff 2 closest to the conveyor belt on conveyor 1 and placing it into a cosmetic box. The gripper 4 is driven to rotate by an adjusting motor 5, adjusting the orientation of the logo on the ribbon. This specific structure is as follows: Figure 3 As shown, a horizontally arranged first linear slide 6 is provided on one side of the front end of the conveyor 1. A conveying mounting plate 7 is installed on the drive end of the first linear slide 6. A vertically arranged second linear slide 16 is installed on the mounting plate 7, and a fixing plate 8 is installed on its drive end. A connecting seat 9 is installed on the fixing plate 8. An adjusting motor 5 is fixedly installed on the upper end of the connecting seat 9, with the drive end of the adjusting motor 5 facing downwards and fixedly connected to the housing of the pneumatic finger 10. With the drive end of the pneumatic finger 10 facing downwards, a gripper 4 is installed on the drive end of the pneumatic finger 10, which can grasp or release the powder puff 2.

[0058] A vision system 3, including a camera, is also installed above the front end of the conveyor 1. It captures images of the powder puff 2 closest to the production line. The back-end controller of the vision system 3 identifies the ribbon on the powder puff 2 and measures the orientation of the logo on the ribbon. This is used to control the rotation amplitude of the motor 5 to adjust the orientation of the logo on the ribbon.

[0059] To improve production efficiency, the conveying station, gripper 4, and adjusting motor 5 on conveyor 1 are all set up in parallel as two sets, which can be used to install two powder puffs 2 at the same time.

[0060] The working principle of this embodiment is as follows:

[0061] 1. Manually stack the powder puffs 2 one on top of the other inside the feed cylinder 113;

[0062] 2. The cylinder 13 drives the suction head 12 to rise and suction the powder puff 2 at the bottom.

[0063] 3. The cylinder 13 drives the suction head 12 to descend, and the powder puff 2 is placed on the conveyor belt 14 and moves with the conveyor belt 14 towards the assembly line conveyor belt;

[0064] 4. Vision system 3 identifies the orientation of the logo on the ribbon;

[0065] 5. The first linear slide 6 drives the gripper 4 to move towards the conveyor 1, and the second linear slide 16 drives the gripper 4 to descend and grab the powder puff 2 at the head end of the conveyor 1.

[0066] 6. The second linear slide 16 drives the gripper 4 to rise, and the first linear slide 6 drives the gripper 4 to move towards the cosmetic box. During this movement, the adjustment motor 5 rotates a certain amount under the control of the vision system 3, so that the logo on the ribbon rotates to an upright position and is parallel to the logo on the cosmetic box.

[0067] 7. When the powder puff 2 moves to the top of the makeup box and is close to the opening of the makeup box, the second linear slide 16 drives the gripper 4 to descend, the gripper 4 releases the powder puff 2, and the powder puff 2 falls into the makeup box.

[0068] Compared to existing technologies, the advantages of this embodiment are: 1. The vision system 3 automatically identifies the orientation of the ribbon logo on the powder puff 2 and uses the adjustment motor 5 to drive the gripper 4 to rotate precisely, eliminating problems such as logo misalignment and tilting caused by visual fatigue or skill differences during manual operation. This ensures that the logo on each powder puff 2 remains parallel and upright with the logo on the outside of the cosmetic box, significantly improving the product's appearance quality and brand image consistency. 2. The automated mechanism enables continuous conveying, identification, adjustment, and installation of the powder puff 2. Precise positioning of the logo orientation can be completed without manual intervention, overcoming the bottleneck of low efficiency in manual operation. This meets the needs of large-scale assembly line production, significantly shortens the production cycle, and increases overall capacity. 3. By replacing repetitive manual operations with automated equipment, the reliance on operator skill and attention is reduced, labor intensity is lowered, and errors caused by fatigue are reduced, which helps save labor costs and improve the working environment.
