Description

Technical Field

[0001] This invention relates to the field of product assembly technology, specifically to a cosmetic container assembly equipment and process. Background Technology

[0002] Cosmetic containers typically consist of a bottle body and a cap. During assembly, specialized assembly equipment is used to assemble each component of the bottle body and cap separately. After the bottle body and cap are assembled separately, the assembled cap is screwed onto the assembled bottle body to complete the final assembly of the entire cosmetic container.

[0003] The lid of a cosmetic container includes an inner lid and an outer lid. During assembly, a robotic arm is typically used to move the outer lid to the pressing station first. Then, the robotic arm pre-inserts the inner lid onto the outer lid and releases it. Next, the pressing mechanism presses the inner lid into the outer lid. Obviously, only by ensuring that the outer lid is placed on the pressing station by the robotic arm first can the assembly of the inner and outer lids be achieved, thus forming a lid that meets the requirements.

[0004] However, in actual assembly processes, the outer cover often fails to be successfully moved to the pressing station by the robotic arm. In this case, the inner cover continues to be moved to the set position by the robotic arm and released, and then continues to be pressed by the pressing mechanism. Obviously, this will lead to assembly failure of the inner and outer covers due to the lack of the outer cover, resulting in defective products with missing outer covers. To solve this problem, existing technologies use an additional special detection mechanism in the process after the outer cover has moved to the pressing station to check whether there is an outer cover at the pressing station. If there is no outer cover, the robotic arm will not release the inner cover, thus successfully canceling the assembly of the inner and outer covers and avoiding defective products with missing outer covers, as illustrated in the invention patent application number 202210918456.0. However, adding an additional testing mechanism will undoubtedly increase the manufacturing cost of the equipment and the number of operating procedures. Therefore, how to prevent the inner cover from being released by the robot arm when there is no outer cover at the pressing station without adding an additional testing mechanism or additional testing procedures, and thus avoid defective products with missing outer covers, is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a cosmetic container assembly device and process to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cosmetic container assembly device, comprising a pressing station for placing an outer cap, a gripper for gripping an inner cap, and a driving component for moving the gripper. The pressing station includes a fixed hollow platform and a placement groove located inside the hollow platform. The outer cap is pressed and inserted into the placement groove, forming a gap between it and the hollow platform.

[0007] The gripper includes a fixed plate fixedly connected to the power output end of the drive component and two clamping plates arranged opposite to each other and elastically rotatably mounted on the fixed plate. The bottoms of the two clamping plates are elastically pressed inward to clamp the inner cover.

[0008] A central column is fixedly installed on the fixed plate, and a locking element for locking the two clamping plates is provided between the central column and the two clamping plates.

[0009] During the process of the drive component driving the gripper to move downwards to assemble the inner cover and the outer cover, when there is no outer cover at the pressing station, the bottom of the two clamps are inserted into the gap to prevent the inner cover from being released.

[0010] When there is an outer cover at the pressing station, the bottom inner sides of the two clamping plates first slide against the outer cover to make the two clamping plates rotate and release the inner cover, and then slide against the hollow platform to make the two clamping plates rotate further and separate from the outer cover, and drive the locking device to lock the two clamping plates.

[0011] In the aforementioned cosmetic container assembly equipment, a pressing plate is fixedly installed on the central column. The pressing plate abuts against the top of the inner cover and is offset from the outer cover so that the pressing plate presses the inner cover into the outer cover during the process of the gripper moving the inner cover downward.

[0012] In the aforementioned cosmetic container assembly equipment, the clamping plate includes an outwardly extending plate located at the bottom. The inner wall of the outwardly extending plate is an outwardly extending inclined surface. During the downward movement of the two clamping plates, the two inclined surfaces are driven to slide and abut against the top of the inner cover, the top of the outer cover, and the top of the hollow platform, so that the two clamping plates are pushed outward and rotated by the inner cover, the outer cover, and the hollow platform.

[0013] The aforementioned cosmetic container assembly equipment includes two locking plates that are fixedly connected to the two clamping plates one-to-one, and a round seat that is elastically slidably inserted into the central column. The top of the round seat is fixedly installed with two sets of locking pins that correspond one-to-one with the two locking plates. The bottom of the locking plate is provided with a slot for inserting and cooperating with the locking pins. In the initial state, the top of the two sets of locking pins elastically abuts against the bottom of the corresponding locking plate. During the process of the hollow platform pushing the two clamping plates to rotate, the two sets of locking pins are driven to insert into the corresponding slots to lock the two clamping plates.

[0014] The aforementioned cosmetic container assembly equipment also includes an auxiliary plate located above the gripper. A top rod is fixedly installed on the sliding seat. The top of the top rod passes through the fixed plate and abuts against the bottom of the auxiliary plate. During the process of the drive unit driving the gripper to move up and reset, the top of the top rod is driven to press against the auxiliary plate, so that the top rod drives the sliding seat to slide down elastically, thereby causing the two sets of locking pins to disengage from the corresponding locking slots.

[0015] In the aforementioned cosmetic container assembly equipment, the fixed plate includes a lifting plate connected to the power output end of the driving component. Two support plates are fixedly mounted on the lifting plate and rotatably connected to the two clamping plates in a one-to-one correspondence. A set of tension springs is connected between each of the two clamping plates and the two support plates.

[0016] In the aforementioned cosmetic container assembly equipment, a rubber ring is installed in the placement slot, and the inner wall of the rubber ring is pressed tightly against the outer surface of the outer cover.

[0017] In the aforementioned cosmetic container assembly equipment, a coating cotton is provided on the central column, and the coating cotton is soaked in lubricating oil. During the pressing process between the inner cover and the outer cover, the coating cotton is inserted into the inner cover to apply lubricating oil to the inner wall of the inner cover.

[0018] In the aforementioned cosmetic container assembly equipment, there are two application cotton pads, each connected to two clamping plates via a connecting rod. The two application cotton pads are slidably arranged. In the initial state, the outer diameter of the two application cotton pads is smaller than the diameter of the inner cavity of the inner cover. As the hollow platform pushes the two clamping plates to rotate, it causes the two application cotton pads to slide so that the outer surfaces of the two application cotton pads press against the inner wall of the inner cover.

[0019] A cosmetic container assembly process, based on the aforementioned cosmetic container assembly equipment, includes the following steps:

[0020] S1, Outer cover loading: The outer cover is placed into the pressing station by a robotic arm;

[0021] S2, Inner cover loading: The drive unit drives the gripper to clamp the inner cover between the two clamping plates and moves the gripper to the top of the pressing station. At this time, if there is an outer cover at the pressing station, the outer cover and the inner cover are coaxial.

[0022] S3, Pressing: The driving component moves the gripper holding the inner cover down. When there is no outer cover at the pressing station, the bottom of the two clamping plates is inserted into the gap formed between the outer cover and the hollow platform. At this time, the inner cover is not released. When there is an outer cover at the pressing station, the bottom of the inner cover is first inserted into the outer cover. Then, the bottom inner walls of the two clamping plates press the top of the outer cover to make the two clamping plates rotate elastically and release the inner cover. After that, the pressing plate on the central column continuously presses the inner cover into the outer cover. At the same time, the bottom inner walls of the two clamping plates press the top of the hollow platform to make the two clamping plates rotate further. The further rotation of the two clamping plates drives the two clamping plates to separate from the outer cover, while also driving the locking component to lock the two clamping plates, keeping the two clamping plates in a state of separation from the outer cover.

[0023] S4, Reset: After pressing is completed, the drive unit moves the gripper up, and the two clamps separate from the outer cover, so that the pressed outer cover and inner cover remain in the pressing station for the next assembly process.

[0024] Beneficial Effects: In the above technical solution, the cosmetic container assembly equipment and process provided by the present invention, through improvements to the gripper, cleverly utilizes the cooperation between the two clamping plates and the outer cover, the hollow platform, and the locking component. This ensures that when there is no outer cover at the pressing station, the two clamping plates do not contact the outer cover or the hollow platform, thus keeping the inner cover firmly clamped and preventing defective products lacking an outer cover. When there is an outer cover at the pressing station, the sliding contact between the two clamping plates and the outer cover allows the two clamping plates to be pushed and rotated by the outer cover, releasing the inner cover. At this point, the inner and outer covers are combined. Then, the sliding contact between the two clamping plates and the hollow platform further rotates the two clamping plates, pushing them. This not only separates the two clamping plates from the outer cover but also locks them in place with the locking component. Therefore, the gripper will not pick up the outer and inner covers when resetting, leaving them at the pressing station to be transported to the next process. As can be seen, the present invention ingeniously utilizes the presence of the outer cover to trigger the gripper to release the inner cover. When the outer cover is not present at the pressing station, the inner cover will not be released. There is no need to provide an additional detection mechanism, and the separate detection process is also eliminated. This achieves the goal of preventing the inner cover from being released when the outer cover is not at the pressing station, thereby avoiding defective products with missing outer covers and effectively solving the shortcomings of the prior art.

[0025] Furthermore, during the downward movement of the gripper, the inner cover is pressed against the outer cover by the pressing plate, thus eliminating the need for subsequent pressing processes and producing an unexpected technical effect. Attached Figure Description

[0046] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] First embodiment:

[0048] like Figure 1-17As shown, an embodiment of the present invention provides a cosmetic container assembly device, including a pressing station for placing an outer cap 20, a gripper for gripping an inner cap 21, and a driving component for driving the gripper to move. The pressing station includes a hollow platform 19 fixedly arranged and a placement groove 1801 located inside the hollow platform 19. The outer cap 20 is pressed and inserted into the placement groove 1801 and forms a gap with the hollow platform 19.

[0049] The gripper includes a fixed plate fixedly connected to the power output end of the drive component and two clamping plates 6 arranged opposite to each other and elastically rotatably mounted on the fixed plate. The bottoms of the two clamping plates 6 are elastically pressed inward to clamp the inner cover 21.

[0050] A central column 1 is fixedly installed on the fixed plate, and a locking element for locking the two clamping plates 6 is provided between the central column 1 and the two clamping plates 6;

[0051] During the process of the drive unit driving the gripper to move the inner cover 21 downward and assembling the outer cover 20, when there is no outer cover 20 at the pressing station, the bottom of the two clamping plates 6 are inserted into the gap so that the inner cover 21 is not released.

[0052] When the pressing station has an outer cover 20, the bottom inner sides of the two clamping plates 6 first slide against the outer cover 20 to make the two clamping plates 6 rotate and release the inner cover 21, and then slide against the hollow platform 19 to make the two clamping plates 6 rotate further and separate from the outer cover 20 and drive the locking member to lock the two clamping plates 6.

[0053] The cosmetic container assembly equipment provided in this embodiment is used for pressing and assembling the outer cap 20 and the inner cap 21. The terms related to direction and position in this embodiment are relative to the accompanying drawings. Specifically, the cosmetic container assembly equipment includes a turntable 18, which is driven to rotate by a drive motor. The number of pressing stations is multiple and arranged circumferentially on the top of the turntable 18. The pressing stations are used to press the inner cap 21 into the outer cap 20. The placement groove 1801 is opened on the top of the turntable 18. The bottom of the outer cap 20 is pressed and inserted into the placement groove 1801. The outer cap 20 is conveyed by a first feeding mechanism and removed from the first feeding mechanism by a robot and inserted into the placement groove 1801. The design of the first feeding mechanism for conveying the outer cap 20 and the robot for gripping the outer cap 20 are both existing technologies and will not be described in detail. When the outer cover 20 is pressed and inserted into the placement groove 1801, an annular gap is formed between the outer cover 20 and the hollow platform 19, for insertion and engagement with the bottoms of the two clamping plates 6 on the gripper. The inner cover 21 is conveyed by the second feeding mechanism and grasped by the gripper, such as... Figure 1 and 3As shown, the second feeding mechanism includes a bracket and a geared motor (or servo motor). Two rotating wheels 24 are rotatably arranged opposite each other on the left and right sides of the bracket, and the two rotating wheels 24 are fixedly connected coaxially through a shaft. The output shaft of the geared motor (or servo motor) is keyed to the rotating wheel 24 on the left side of the bracket or to the rotating wheel 24 on the right side of the bracket. A conveyor belt 23 is fitted on each of the two rotating wheels 24 on the left and the two rotating wheels 24 on the right side of the bracket. Multiple conveyor plates 22 are fixedly installed between the two conveyor belts 23 at equal intervals. The conveyor plates 22 have blind holes for inserting the inner cover 21. When the geared motor (or servo motor) is started, it drives the corresponding two rotating wheels 24 to rotate. The rotating wheels 24 drive the two conveyor belts 23 to rotate. The conveyor belts 23 then drive the multiple conveyor plates 22 to move to realize the conveying of the inner cover 21. The structures of the first feeding mechanism and the second feeding mechanism can be the same. The driving component that moves the gripper enables it to move vertically and horizontally. The driving component includes a column 25, on which a horizontal frame 26 is fixedly mounted. A horizontal sliding plate 30 is horizontally slidable on the horizontal frame 26. A first cylinder is connected to the horizontal sliding plate 30 to drive it to reciprocate horizontally. A set of opposing vertical guide rails 31 are fixedly mounted on the side of the horizontal sliding plate 30. A vertical sliding seat 29 is vertically slidable on the side of the horizontal sliding plate 30 via the set of vertical guide rails 31. A second cylinder 27 is also fixedly mounted on the horizontal sliding plate 30. A sliding plate 28, which is connected to the power output end of the second cylinder 27, is fixedly installed on the side of the 9. The second cylinder 27 drives the sliding plate 28 and the vertical sliding seat 29 to slide back and forth in the vertical direction. An auxiliary plate 33 is fixedly installed on the side of the sliding plate 28. A third cylinder 32 is fixedly installed on the auxiliary plate 33. The power output end of the third cylinder 32 passes through the auxiliary plate 33 and is fixedly connected to a lifting plate 35. The power output end of the third cylinder 32 is the power output end of the driving component. The third cylinder 32 drives the lifting plate 35 to slide back and forth in the vertical direction. The lifting plate 35 then drives the gripper to slide back and forth in the vertical direction. The working principle of the drive unit is as follows: First, the first cylinder drives the gripper to move above the corresponding conveyor plate 22. Then, the second cylinder 27 drives the gripper to move vertically downward to grab the inner cover 21 on the conveyor plate 22. Next, the second cylinder 27 drives the gripper holding the inner cover 21 to move upward. Then, the first cylinder drives the gripper holding the inner cover 21 to move towards the pressing station until it moves directly above the outer cover 20 located in the pressing station. Then, the third cylinder 32 drives the gripper and the inner cover 21 to move vertically downward and insert into the outer cover 20.During the process of the gripper moving down to grasp the inner cover 21, the inner cover 21 is inserted between the two clamping plates 6 from the bottom. The two clamping plates 6 are elastically rotated and clamped by the elastic force. The clamping plates 6 are arc-shaped. When the inner cover 21 is clamped by the two clamping plates 6, its lower half is located below the two clamping plates 6, and its upper half is located between the two clamping plates 6.

[0054] A central column 1 is fixedly installed on the fixed plate. The central column 1 is located between two clamping plates 6, and a locking element is provided between the central column 1 and the two clamping plates 6 to lock the two clamping plates 6. When the two clamping plates 6 are locked, they cannot be reset. The specific method and function of the locking element locking the clamping plates 6 are detailed below.

[0055] When the inner cover 21 is inserted downward into the outer cover 20 for assembly, two different operations will occur depending on whether the outer cover 20 is present at the pressing station. Specifically, when the outer cover 20 is not present at the pressing station, it is not desirable for the inner cover 21 to be released, otherwise a defective product with a missing outer cover 20 will be produced. Therefore, in this embodiment, when the third cylinder 32 drives the gripper holding the inner cover 21 to move downward, the bottom of the two clamping plates 6 corresponds to the gap. As the gripper moves downward, the bottom of the two clamping plates 6 is continuously inserted into the gap until it moves to the lowest position. During this process, the two clamping plates 6 maintain the state of clamping the inner cover 21, so that the inner cover 21 will not be released, and thus a defective product with a missing outer cover 20 will not be produced.

[0056] When the outer cover 20 is present at the pressing station, as the gripper holding the inner cover 21 moves downward, the bottom of the inner cover 21 first inserts into the outer cover 20. Then, the inner bottom sides of the two clamping plates 6 first slide against the top of the outer cover 20. Since the outer diameter of the outer cover 20 is larger than the outer diameter of the inner cover 21, the two clamping plates 6 are pushed to rotate by the outer cover 20 during the sliding contact process. After the two clamping plates 6 rotate, they release the clamping force on the inner cover 21, thereby releasing the inner cover 21. Then, the bottom inner sides of the two clamping plates 6 slide against the top of the hollow platform 19 to allow the two clamping plates 6 to rotate further. The further rotation of the two clamping plates 6 moves the two clamping plates 6 away from the outer cover 20, thereby separating the two clamping plates 6 from the outer cover 20. The further rotation of the two clamping plates 6 drives the two locking members to lock the two clamping plates 6 so that the two clamping plates 6 cannot be reset. Then, the third cylinder 32 drives the gripper to move up and reset. Since the two clamping plates 6 are not in contact with the outer cover 20 at this time, the outer cover 20 and the inner cover 21 remain in the pressing position.

[0057] This invention, through structural improvements to the gripper, cleverly utilizes the cooperation between the two clamping plates 6, the outer cover 20, the hollow platform 19, and the locking mechanism. This ensures that when the pressing station lacks the outer cover 20, the two clamping plates 6 do not contact the outer cover 20 or the hollow platform 19, thus guaranteeing that the two clamping plates 6 always hold the inner cover 21 firmly and prevents it from being released, thereby avoiding defective products lacking the outer cover 20. Conversely, when the pressing station has the outer cover 20, the sliding contact between the two clamping plates 6 and the outer cover 20 allows the two clamping plates 6 to be held firmly by the outer cover. The outer cover 20 is pushed and rotated to release the inner cover 21. At this time, the inner cover 21 and the outer cover 20 are combined together. Then, the two clamping plates 6 are pushed by the hollow platform 19 to rotate the clamping plates 6 further. At this time, the two clamping plates 6 not only separate from the outer cover 20, but also lock the two clamping plates 6 with locking elements. Therefore, when the gripper resets, it will not grab the outer cover 20 and the inner cover 21. The outer cover 20 and the inner cover 21 can be left in the pressing station and transported to the next process. It can be seen that the present invention ingeniously utilizes the presence of the outer cover 20 to trigger the gripper to release the inner cover 21. When the outer cover 20 is not present in the pressing station, the inner cover 21 will not be released. There is no need to provide an additional detection mechanism, and the separate detection process is also eliminated. The purpose of preventing the inner cover 21 from being released can be achieved, thereby avoiding defective products with missing outer cover 20, which can effectively solve the shortcomings of the prior art.

[0058] Furthermore, a pressing plate 2 is fixedly installed on the central column 1. The pressing plate 2 abuts against the top of the inner cover 21 and is offset from the outer cover 20 so that the pressing plate 2 presses the inner cover 21 into the outer cover 20 during the process of the gripper moving the inner cover 21 downward. Specifically, the pressing plate 2 is fixedly connected to the outer surface of the central column 1. The bottom of the pressing plate 2 abuts against the top of the inner cover 21. First, during the process of the gripper grabbing the inner cover 21 on the conveyor plate 22, as the second cylinder 27 drives the gripper to move down continuously, the inner cover 21 enters between the two clamping plates 6 and moves closer to the pressing plate 2. Then, during the process of the third cylinder 32 driving the gripper to move down, when the bottom of the inner cover 21 is inserted into the outer cover 20, the outer cover 20 squeezes the inner cover 21 to slide upward so that the top of the inner cover 21 abuts against the bottom of the pressing plate 2. Then, as the gripper continues to move down, the pressing plate 2 pushes the inner cover 21 to continuously insert into the outer cover 20 until the pressing plate 2 completely presses the inner cover 21 into the outer cover 20. At this time, the two clamping plates 6 also complete the separation from the outer cover 20 and are locked by the locking components.

[0059] Through the above structural design, the inner cover 21 and the outer cover 20 are pressed together during the downward movement of the gripper, thus eliminating the need for subsequent pressing processes and producing an unexpected technical effect.

[0060] In this embodiment, the clamping plate 6 includes an outwardly extending plate 601 located at the bottom. The outwardly extending plate 601 is arc-shaped, and the inner wall of the outwardly extending plate 601 is an outwardly extending inclined surface 602, so that the inclined surface 602 is inclined so that during the downward movement of the two clamping plates 6, the two inclined surfaces 602 are driven to slide and abut against the top of the inner cover 21, the top of the outer cover 20, and the top of the hollow platform 19, so that the two clamping plates 6 are pushed outward and rotated by the inner cover 21, the outer cover 20, and the hollow platform 19.

[0061] In this embodiment, the locking component includes two locking plates 7 that are fixedly connected to the two clamping plates 6 one-to-one, and a round seat 4 that is elastically slidably inserted into the central column 1. The top of the round seat 4 is fixedly installed with two sets of locking pins 401 that correspond one-to-one with the two locking plates 7. The bottom of the locking plate 7 is provided with a slot 701 that engages with the locking pins 401. In the initial state, the top of the two sets of locking pins 401 elastically abuts against the bottom of the corresponding locking plate 7. During the process of the hollow platform 19 pushing the two clamping plates 6 to rotate, the two sets of locking pins 401 are driven to insert into the corresponding slots 701 to lock the two clamping plates 6. Specifically, two locking plates 7 are located inside the two clamping plates 6. A slot 701 is formed at the bottom of the locking plate 7. A sliding hole 103 is formed at the top of the central post 1. A sliding seat 4 is slidably mounted within the sliding hole 103 via a spring 10. The spring 10 is located within the sliding hole 103 and abuts against the bottom of the sliding seat 4. Two upper notches 101, corresponding one-to-one with the two locking plates 7, are formed on the central post 1. The two locking plates 7 pass through the two upper notches 101 one-to-one. Two sets of locking posts 401 fixedly mounted on the top of the sliding seat 4 slide against the bottoms of the two locking plates 7 one-to-one. Under the limiting action of the locking plates 7, the spring 10 is initially compressed. The two clamping plates 6 and the outer cover 2... During the sliding contact process, the two clamping plates 6 drive the two locking plates 7 to rotate inward. At this time, the slot 701 moves closer to the locking post 401. When the two clamping plates 6 slide against the hollow platform 19, the two clamping plates 6 further drive the two locking plates 7 to rotate inward, so that the two locking posts 401 enter the corresponding slots 701 respectively. At this time, under the elastic force of the compression spring 10, the round seat 4 and the locking post 401 slide upward so that the two sets of locking posts 401 are inserted into the corresponding slots 701. Under the limiting action of the locking posts 401, the two clamping plates 6 are locked. When the two locking posts 401 disengage from the corresponding slots 701, the two clamping plates 6 will automatically reset under the action of elastic rotation force.

[0062] The top plate 3 is fixedly installed on the top of the central column 1, and the top plate 3 is fixedly connected to the fixing plate.

[0063] It also includes an auxiliary plate 33 located above the gripper. A top rod 5 is fixedly installed on the round slide seat 4. The top of the top rod 5 passes through the fixed plate and abuts against the bottom of the auxiliary plate 33. During the process of the drive unit driving the gripper to move up and reset, the top of the top rod 5 is driven to press the auxiliary plate 33 so that the top rod 5 drives the round slide seat 4 to slide down elastically, thereby causing the two sets of locking pins 401 to disengage from the corresponding locking slots 701. Specifically, since the auxiliary plate 33 is fixedly connected to the sliding plate 28, and the sliding plate 28 is driven to move by the second cylinder 27, while the gripper is driven to move by the third cylinder 32, when the third cylinder 32 drives the gripper to move upward and reset, it will cause the top of the push rod 5 to continuously approach the auxiliary plate 33. When the third cylinder 32 drives the gripper to reset, the top of the push rod 5 is pressed against the bottom of the auxiliary plate 33, and the push rod 5 and the round sliding seat 4 slide downward elastically. At this time, the two sets of locking pins 401 slide out from the corresponding locking slots 701, thereby canceling the locking pins 401 from limiting the locking plate 7, so that the two clamping plates 6 are unlocked. Under the action of elastic force, the two clamping plates 6 realize rotation and reset, preparing for the next clamping of the inner cover 21. It can be seen that the present invention utilizes the action of the gripper moving upward and resetting to also realize the automatic unlocking of the two clamping plates 6. The number of each set of card posts 401 is one or more. When there are multiple card posts 401, the arrangement direction of the multiple card posts 401 is adapted to the direction of the card slot 701 so that the multiple card posts 401 can be inserted into the card slot 701 at the same time.

[0064] In this embodiment, the fixed plate includes a lifting plate 35 connected to the power output end of the driving component. Two support plates 8 are fixedly mounted on the lifting plate 35, each corresponding to and rotatably connected to one of the two clamping plates 6. A set of tension springs 9 connects each of the two clamping plates 6 and the two support plates 8. Specifically, the two clamping plates 6 are located between the two support plates 8. A first connecting seat 603 is fixedly installed on the outer side of the clamping plate 6, and a second connecting seat 801 corresponding to the first connecting seat 603 is fixedly installed on the inner side of the support plate 8. The first connecting seat 603 and the second connecting seat 801 are rotatably connected via a rotating shaft 11. The clamping plate 6 rotates around the rotating shaft 11, and the tension spring 9 is located above the rotating shaft 11. One end of the tension spring 9 is fixedly connected to the inner side of the support plate 8, and the other end is fixedly connected to the outer side of the clamping plate 6. Under the elastic force of the tension spring 9, the clamping plate 6 achieves elastic linkage.

[0065] In this embodiment, a rubber ring 34 is installed in the placement groove 1801. The inner wall of the rubber ring 34 is pressed tightly against the outer surface of the outer cover 20, thereby providing stability of the outer cover 20 at the pressing position. When the outer cover 20 is inserted into the placement groove 1801, its upper half is located outside the placement groove 1801, so that the two clamps 6 can abut against the outer cover 20 during the downward movement.

[0066] In this embodiment, a sizing agent 15 is provided on the central column 1. The sizing agent 15 is soaked in lubricating oil. During the pressing process between the inner cap 21 and the outer cap 20, the sizing agent 15 is inserted into the inner cap 21 to apply lubricating oil to the inner wall of the inner cap 21. Specifically, by utilizing the lubricating oil soaked in the sizing agent 15, the lubricating oil on the sizing agent 15 can be applied to the threads on the inner wall of the inner cap 21 during the pressing process, which facilitates the subsequent screwing of the cap to the bottle body.

[0067] Furthermore, there are two applicator pads 15, each connected to one of the two clamping plates 6 via an adapter rod 14. The two applicator pads 15 are slidably positioned. Initially, the outer diameter of the two applicator pads 15 is smaller than the diameter of the inner cavity of the inner cover 21. As the hollow platform 19 pushes the two clamping plates 6 to rotate, it causes the two applicator pads 15 to slide, so that the outer surfaces of the two applicator pads 15 press against the inner wall of the inner cover 21. Specifically, the outer diameters of the two applicator pads 15 are coaxial with the inner cover 21. In actual operation, when the outer diameters of the two applicator pads 15 are directly larger than the diameter of the inner cavity of the inner cover 21, it is easy for the inner cover 21 to squeeze the applicator pads 15 when the two applicator pads 15 are inserted into the inner cover 21, causing the lubricating oil soaked on the applicator pads 15 to be squeezed to the outside of the inner cover 21. Conversely, when the outer diameters of the two applicator pads 15 are directly smaller than the diameter of the inner cavity of the inner cover 21, the lubricating oil on the two applicator pads 15 cannot be applied to the inner wall of the inner cover 21. To solve this technical problem, this application has optimized the above-mentioned structure. Since the outer circles of the two applicator cotton balls 15 are directly smaller than the diameter of the inner cavity of the inner cover 21, the two applicator cotton balls 15 will not contact the inner cover 21 when inserted into it, thus preventing the lubricating oil from overflowing to the outside of the inner cover 21. During the process of the hollow platform 19 pushing the two clamping plates 6 to rotate, the rotation of the clamping plates 6 drives the corresponding applicator cotton balls 15 to slide through the adapter rod 14. The sliding of the two applicator cotton balls 15 causes the outer side to press against the inner wall of the inner cover 21, thereby achieving the application of lubricating oil.

[0068] The central column 1 has a recessed hole at its bottom, and two inner plates 12 are fixedly installed inside the recessed hole. Tracks 1201 are provided on the opposite surfaces of the two inner plates 12. The central column 1 has two lower notches 102 that communicate with the recessed hole. Each of the two lower notches 102 corresponds to one of the two adapter rods 14, which pass through the corresponding lower notches 102. A connecting plate 13 is fixedly installed on the top of each of the two applicator pads 15. Guide plates 1301 are fixedly installed on both the front and rear sides of the connecting plate 13. The guide plates 1301 connect to the tracks... The sliding connection of the 1201 allows the two connecting plates 13 to slide between the two inner plates 12. The two connecting plates 13 correspond one-to-one with the two adapter rods 14. One end of the adapter rod 14 is rotatably connected to the connecting plate 13, and the other end is rotatably connected to the third connecting seat 604 installed on the clamping plate 6. When the two clamping plates 6 rotate, they pull the corresponding adapter rod 14, which pulls the corresponding connecting plate 13 to slide. The connecting plate 13 then drives the corresponding applicator 15 to move so that the applicator 15 squeezes the inner wall of the inner cover 21 to apply lubricating oil. Two return springs 17 are connected between the two connecting plates 13. The two ends of the return springs 17 are fixedly connected to the two connecting plates 13 respectively. A limiting block 16 located between the two return springs 17 is fixedly installed on one of the connecting plates 13. When the two clamping plates 6 are reset, the return springs 17 are used to drive the two connecting plates 13 to reset, and the limiting block 16 is used to limit the two connecting plates 13. In the initial state, the end of the limiting block 16 abuts against the connecting plate 13 so that the two applicator cotton 15 do not squeeze each other.

[0069] The pressing plate 2 has two clearance openings 201 that correspond one-to-one with the two adapter rods 14, so that the pressing plate 2 will not obstruct the rotation of the two adapter rods 14.

[0070] Second embodiment:

[0071] A cosmetic container assembly process includes the following steps:

[0072] S1, Outer cover 20 loading: The outer cover 20 is placed into the pressing station by a robotic arm;

[0073] S2, Inner cover 21 loading: The drive unit drives the gripper to clamp the inner cover 21 between the two clamping plates 6 and moves the gripper to the top of the pressing station. At this time, if there is an outer cover 20 in the pressing station, the outer cover 20 and the inner cover 21 are coaxial.

[0074] S3, Pressing: The driving component moves the gripper holding the inner cover 21 downward. When there is no outer cover 20 at the pressing station, the bottom of the two clamping plates 6 is inserted into the gap formed between the outer cover 20 and the hollow platform 19. At this time, the inner cover 21 is not released. When there is an outer cover 20 at the pressing station, the bottom of the inner cover 21 is first inserted into the outer cover 20. Then, the bottom inner walls of the two clamping plates 6 press the top of the outer cover 20 to make the two clamping plates 6 rotate elastically and release the inner cover 21. After that, the pressing plate 2 on the central column 1 continuously presses the inner cover 21 into the outer cover 20. At the same time, the bottom inner walls of the two clamping plates 6 press the top of the hollow platform 19 to make the two clamping plates 6 rotate further. The further rotation of the two clamping plates 6 drives the two clamping plates 6 to separate from the outer cover 20, while also driving the locking component to lock the two clamping plates 6, so that the two clamping plates 6 remain separated from the outer cover 20.

[0075] S4, Reset: After pressing is completed, the drive unit moves the gripper up, and at this time the two clamping plates 6 separate from the outer cover 20, so that the pressed outer cover 20 and inner cover 21 remain at the pressing station for the next assembly process.

[0076] In step S3, the locking component includes two locking plates 7 that are fixedly connected to the two clamping plates 6 one-to-one, and a round seat 4 that is elastically slidably inserted into the central column 1. The top of the round seat 4 is fixedly installed with two sets of locking pins 401 that correspond one-to-one with the two locking plates 7. The bottom of the locking plate 7 is provided with a slot 701 that engages with the locking pins 401. In the initial state, the top of the two sets of locking pins 401 elastically abuts against the bottom of the corresponding locking plate 7. During the process of the hollow platform 19 pushing the two clamping plates 6 to rotate, the two sets of locking pins 401 are driven to insert into the corresponding slots 701 to lock the two clamping plates 6. Specifically, two locking plates 7 are located inside the two clamping plates 6. A slot 701 is formed at the bottom of the locking plate 7. A sliding hole 103 is formed at the top of the central post 1. A sliding seat 4 is slidably mounted within the sliding hole 103 via a spring 10. The spring 10 is located within the sliding hole 103 and abuts against the bottom of the sliding seat 4. Two upper notches 101, corresponding one-to-one with the two locking plates 7, are formed on the central post 1. The two locking plates 7 pass through the two upper notches 101 one-to-one. Two sets of locking posts 401 fixedly mounted on the top of the sliding seat 4 slide against the bottoms of the two locking plates 7 one-to-one. Under the limiting action of the locking plates 7, the spring 10 is initially compressed. The two clamping plates 6 and the outer cover 2... During the sliding contact process, the two clamping plates 6 drive the two locking plates 7 to rotate inward. At this time, the slot 701 moves closer to the locking post 401. When the two clamping plates 6 slide against the hollow platform 19, the two clamping plates 6 further drive the two locking plates 7 to rotate inward, so that the two locking posts 401 enter the corresponding slots 701 respectively. At this time, under the elastic force of the compression spring 10, the round seat 4 and the locking post 401 slide upward so that the two sets of locking posts 401 are inserted into the corresponding slots 701. Under the limiting action of the locking posts 401, the two clamping plates 6 are locked. When the two locking posts 401 disengage from the corresponding slots 701, the two clamping plates 6 will automatically reset under the action of elastic rotation force.

[0077] In step S4, an auxiliary plate 33 located above the gripper is also included. A top rod 5 is fixedly installed on the sliding seat 4. The top of the top rod 5 passes through the fixed plate and abuts against the bottom of the auxiliary plate 33. During the process of the drive unit driving the gripper to move up and reset, the top of the top rod 5 is driven to press the auxiliary plate 33 so that the top rod 5 drives the sliding seat 4 to slide down elastically, thereby causing the two sets of locking pins 401 to disengage from the corresponding locking slots 701. Specifically, since the auxiliary plate 33 is fixedly connected to the sliding plate 28, the sliding plate 28 is driven to move by the second cylinder 27, and the gripper is driven to move by the third cylinder 32, when the third cylinder 32 drives the gripper to move up and reset, it will cause the top of the push rod 5 to continuously approach the auxiliary plate 33. When the third cylinder 32 drives the gripper to reset, the top of the push rod 5 is pressed against the bottom of the auxiliary plate 33, and the push rod 5 and the round sliding seat 4 slide downward elastically. At this time, the two sets of locking pins 401 slide out from the corresponding locking slots 701, thereby canceling the locking pins 401 from limiting the locking plate 7, so that the two clamping plates 6 are unlocked. Under the action of the elastic force, the two clamping plates 6 realize rotation reset, preparing for the next clamping of the inner cover 21.

[0078] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
