[0003] The patent with the application publication number CN116065374A discloses a three-dimensional collar stretching mechanism, which includes a first claw and a second claw arranged side by side left and right. Both the first claw and the second claw include an upper claw and a lower claw arranged side by side up and down and capable of moving relatively far away or close to each other up and down, so as to realize the three-dimensional stretching of the collar in the up, down, left and right directions, enable the clothes hanger to smoothly penetrate into the collar, and when the two arms of the hanger are unfolded, it is not easy to lift the clothing body to cause clothing wrinkles, and the automatic hanging is completed while keeping the clothing flat and beautiful.

[0004] The existing collar stretching mechanisms are designed to operate when the clothes are in a flat state, which requires the clothes to be first laid flat and unfolded, and this usually requires additional devices and a large operating space to achieve. However, this design is not suitable for space-constrained environments, such as small wardrobes or other compact spaces, because they cannot provide enough space to accommodate the devices and processes required for laying out the clothes flat. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a collar stretching mechanism in a clothing hanging manner, which can be applied to a wardrobe with a relatively small space because no additional laying-out mechanism is required.

[0006] The core technical concept of the utility model lies in a double-gripping device system. The first gripping device uses a rotating electric claw to fix the clothing in a hanging state, and the second gripping device combines an electric push rod, a linkage mechanism and a pneumatic soft claw assembly to realize the automatic stretching and precise control of the clothing collar. The whole system realizes automatic operation through intelligent control, adapts to space-constrained environments, simplifies the clothing sorting process, avoids clothing wrinkles, and improves the sorting efficiency and quality.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: a collar stretching mechanism in a clothing hanging state,

[0008] including a first gripping device for keeping the clothing in a hanging state and a second gripping device for keeping the clothing collar in an open state;

[0009] The first grasping device includes a rotatable electric claw clip; it is used to grasp the clothing and keep it in a suspended state, with the collar of the clothing in a closed posture.

[0018] When the electric push rod drives the flexible claw assembly to expand through the link mechanism, the angle between the cross arm and the connecting rod increases. At the same time, the first angle gradually decreases, and the second angle gradually increases.

[0019] When the electric push rod drives the flexible claw assembly to retract through the link mechanism, the angle between the connecting rod and the cross arm gradually decreases, the first angle gradually increases, and the second angle gradually decreases.

[0023] When positive-pressure compressed air is introduced, the airbag or the pneumatic chamber expands, and the pneumatic flexible claw loosens the clothing;

[0029] The positioning optoelectronic component communicates with the control system to provide the rotation angle and speed information of the electric claw.

[0030] A further preferred technical solution of the utility model is that: the neckline stretching mechanism in the clothing hanging state further includes a bracket, the first and second grasping devices are installed on the bracket, and the first and second grasping devices are spaced apart by a certain distance.

[0031] A further preferred technical solution of the utility model is that: the pressure of the positive-pressure compressed air is 30-70 kPa, and the pressure of the negative-pressure compressed air is 60-100 kPa.

[0044] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.

[0045] It should be noted that: Similar reference numerals denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it will not be further defined and explained in the subsequent drawings.

[0046] As Figures 1 to 7 shown, a collar opening mechanism 100 in a state of hanging clothes includes a first grasping device 101 for keeping the clothes f in a hanging state and a second grasping device 102 for keeping the collar of the clothes in an open state. The function of the first grasping device 101 is to firmly grasp the clothes to ensure its stable hanging during operation and avoid slipping or twisting. The second grasping device 102 has a special function. Through a specific mechanical structure, it can gently and effectively open the collar of the clothes to an appropriate angle and width, thus facilitating the subsequent insertion of the clothes hanger or other operations.

[0047] This technical means aims to facilitate the convenience of users' operation in a narrow space such as inside a wardrobe, avoiding the extra space required for traditional flat-laying clothes and the possible problem of clothes wrinkles. By optimizing the grasping and opening mechanisms, this mechanism not only improves the efficiency of clothes hanging and sorting, but also ensures the flatness and beauty of the clothes during the operation. The specific technical solutions will be elaborated below:

[0048] The first grasping device 101 includes a rotatable electric claw 10 for grasping the clothes and keeping it in a hanging state, with the collar f1 of the clothes f in a closed posture. It has a high degree of flexibility and adaptability. The rotatable characteristic of the electric claw 10 enables it to grasp the clothes from multiple angles and reduce unnecessary stretching or damage to the clothes during hanging. In addition, the electric drive mechanism of the electric claw 10 provides precise control ability. The operator can control the grasping force of the claw by adjusting the rotation speed and torque of the motor, so as to adapt to clothes of different materials and thicknesses.

[0049] In terms of design, the electric claw 10 adopts a modular concept, which means that this module can quickly replace or upgrade components according to specific application requirements to adapt to the changing industrial environment.

[0050] Further, the second grasping device 102 includes an electric push rod 20, a deformable link mechanism 30, and a flexible claw assembly 40; the electric push rod 20 is connected to the flexible claw assembly 40 through the link mechanism 30; the electric push rod 20 not only serves as a driving force, but through the specific setting of the link mechanism 30, its telescopic movement can be converted into the opening and closing movement of the flexible claw assembly 40. Thereby enabling the flexible claw assembly 40 to flexibly grasp and manipulate the edge of the clothing collar f1, realizing the attitude change from closed to flared, providing convenience for the insertion of the clothes hanger g, as Figure 8 shown, and ultimately enabling the clothes hanger g to fully support the clothes.

[0051] The flexible claw assembly 40 includes a fixed seat 41 connected to the link mechanism 30, a connecting rod b, and a pneumatic flexible claw 43. The fixed seat 41 is connected to the pneumatic flexible claw 43 through the connecting rod b; the pneumatic flexible claw 43 grasps the edge of the clothing collar f1; the fixed seat 41 serves as a connection point and is connected to the pneumatic flexible claw 43 through the connecting rod b, and the spring b1 sleeved on the connecting rod b provides necessary elastic support and buffering effect between the fixed seat 41 and the pneumatic flexible claw 43. Such a configuration not only ensures the operation stability of the flexible claw assembly, but also enables it to pull the clothing collar f1 in an inclined state during operation, realizing more accurate control.

[0052] When the electric push rod 20 expands and contracts, the deformation of the link mechanism 30 drives the pneumatic flexible claw 43 to move between approaching and departing from the clothing f, and changes the clothing collar f1 from a closed attitude to a flared attitude, thereby facilitating the clothes hanger g to enter the clothing collar f1. The characteristic structure of the link mechanism 30 cleverly utilizes the mechanical principle (which will be specifically described below), so that under the drive of the electric push rod 20, the flexible claw assembly 40 can realize the expansion and retraction actions. The change in the angle between the cross arm 33 and the connecting rod b directly affects the attitude and opening / closing force of the flexible claw assembly.

[0053] In addition, in this embodiment, a spring b1 is sleeved on the connecting rod b, and the spring b1 abuts between the fixed seat 41 and the pneumatic flexible claw 43. This configuration not only provides necessary elastic support for the flexible claw assembly 40, but also enhances its stability and buffering ability during operation. In addition, the position of the spring b1 is designed just right, and its top just abuts between the fixed seat 41 and the pneumatic flexible claw 43, which not only ensures the power transmission efficiency of the flexible claw assembly when pulling the clothing collar f1, but also provides guarantee for the compactness during storage.

[0054] When the flexible claw assembly 40 is in the working state, the driving action of the linkage mechanism 30 enables the flexible claw assembly to present an inclined state, effectively pulling and stretching the clothing neckline f1. This technical means makes full use of the mechanical principle and realizes precise operation of the clothing neckline through the precise control of the linkage mechanism 30. When the flexible claw assembly 40 needs to be folded and stored, both the linkage mechanism 30 and the flexible claw assembly 40 can be smoothly folded and retracted, which not only saves space but also facilitates the storage and maintenance of the entire mechanism.

[0055] More specifically, the linkage mechanism 30 includes a first arm 31, a second arm 32, and a cross arm 33; they cooperate together to convert the power of the electric push rod 20 and precisely control the movement of the flexible claw assembly 40.

[0056] The cross arm 33 is connected to the electric push rod 20 through a connecting arm 34, and the inner end of the cross arm 33 is connected to the lower end of the connecting arm 34 through a hinge point, forming a flexible rotation node. Such a design allows the cross arm 33 to swing under the push of the electric push rod 20, thereby driving the movement of the entire linkage mechanism 30.

[0057] Both ends of the first arm 31 are respectively connected to the electric push rod 20 and the cross arm 33, and both ends of the second arm 32 are respectively connected to the electric push rod 20 and the fixed seat 41. The first arm 31 is a straight arm that connects the electric push rod 20 and the cross arm 33, while the second arm 32 is a bent arm that connects the electric push rod 20 and the fixed seat 41. The designs of these two arms not only provide mechanical strength but also achieve different motion characteristics and torque transmission efficiencies through the different shapes of the arm parts.

[0058] The first arm 31 is a straight arm and forms a first angle with the cross arm 33 in the first direction; the second arm 32 is a bent arm and forms a second angle with the connecting rod b in the first direction. When the electric push rod 20 is driven to extend or contract, it causes angle changes of the cross arm 33 and the two arms through the linkage mechanism 30.

[0059] When the flexible claw assembly 40 is unfolded, the angle between the cross arm 33 and the connecting rod b increases, the first angle between the first arm 31 and the cross arm 33 decreases, and the second angle between the second arm 32 and the connecting rod b increases. This angle change enables the flexible claw assembly 40 to be smoothly unfolded and effectively stretch the clothing neckline f1.

[0060] On the contrary, when the electric push rod 20 drives the flexible claw assembly 40 to retract, the angle between the cross arm 33 and the connecting rod b decreases, the first angle increases, and the second angle decreases, causing the flexible claw assembly 40 to fold inward and achieve compact storage.

[0061] Finally, when the flexible claw assembly 40 is fully retracted, the connecting rod b is parallel to the cross arm 33. This not only reflects the ingenious design of the linkage mechanism 30 but also enables the entire mechanism to be stored compactly, facilitating the effective use of space.

[0062] The linkage mechanism 30 allows for fine adjustment and control of the movement of the flexible claw assembly 40 to adapt to the collars f1 of clothes with different shapes and sizes, ensuring the flexibility and adaptability of the operation. By precisely controlling the telescoping of the electric push rod 20, the opening and closing force and angle of the flexible claw assembly 40 can be adjusted to achieve gentle and effective grasping of the clothes, avoiding damage to the clothes. This intelligent and automated design significantly improves the efficiency and quality of clothes sorting.

[0063] In addition, the collar expanding mechanism in this embodiment further includes a bracket 103. The first and second grasping devices are mounted on the bracket 103 and are spaced apart by a certain distance. The bracket 103 is used to firmly support the first and second grasping devices and ensure their stable operation throughout the operation. Of course, preferably, the spacing distance between the first and second grasping devices is adjustable, allowing them to adjust their positions according to the size of the collar to adapt to collars of different widths.

[0064] The first grasping device 101 further includes a driving motor a1, a rotating shaft a2, and an electric gripper body a3. The driving motor a1 is connected to the rotating shaft a2 through its output shaft, and the rotating shaft a2 is fixedly connected to the electric gripper body a3 so that the driving motor a1 controls the electric gripper body a3 to rotate back and forth through the rotating shaft a2. The electric gripper 10 is installed at the lower end of the electric gripper body a3. The driving motor a1 is the power source of the entire grasping device, responsible for providing the required torque and rotational speed to drive the entire system. The driving motor a1 can adopt a high-precision servo motor, ensuring precise control of the electric gripper body a3.

[0065] In addition, as a bridge connecting the driving motor a1 and the electric gripper body a3, the rotating shaft a2 transmits the rotational motion of the motor to the gripper body. This shaft is made of high-strength material, ensuring stability and durability under high loads.

[0066] Moreover, the electric gripper 10 installed at the lower end is convenient for daily inspection and maintenance work because its position is easily accessible, which helps reduce maintenance costs and improve maintenance efficiency. Also, it should be noted that the electric gripper 10 is designed in a small size for precise clamping of clothes, while the electric gripper body a3 is a larger three-dimensional structure that can provide sufficient stability and support force. In this way, the large size of the electric gripper body a3 and the precise clamping ability of the electric gripper 10 together improve the stability and reliability of the entire system, reducing the risk of clothes dropping or being damaged due to unstable clamping.

[0067] The first grasping device 101 further includes a positioning optoelectronic component k, which is installed on the side of the rotating shaft a2 or the side of the electric gripper body a3, and is used to detect the rotation action of the rotating shaft a2 or the electric gripper body a3; the positioning optoelectronic component k can capture and analyze the subtle changes in the rotation angle and speed in real time.

[0068] The positioning optoelectronic component k communicates with the control system to provide the rotation angle and speed information of the electric gripper 10. Through efficient data transmission, the rotation angle and speed information of the electric gripper 10 collected by the positioning optoelectronic component k is sent to the control system in real time. This process not only ensures the precise monitoring of the action of the electric gripper 10, but also realizes the dynamic adjustment and optimization of its action through feedback control, thereby improving the operation accuracy and response speed of the entire grasping device.

[0069] Further preferably, the design of the pneumatic flexible jaw 43 is an innovative means integrating mechanical engineering and pneumatic control technology. The internal pneumatic components, including air bags or pneumatic chambers, are the core components for realizing the opening and closing actions of the flexible jaw. These components are precisely driven by a pneumatic control system, which mainly includes key components such as a gas source (such as an air compressor), a solenoid valve, and a pressure regulator.

[0070] The working principle of the pneumatic control system is based on the flow and pressure change of compressed air. The gas source unit is responsible for providing clean and stable compressed air, while the solenoid valve, as a control component, controls the flow direction of compressed air by responding to electrical signals to realize the opening and closing actions of the flexible jaw. The pressure regulator ensures that the air pressure in the system is maintained within the required working range, so as to ensure that the pneumatic flexible jaw 43 can operate stably and precisely.

[0071] The vent holes on the pneumatic flexible jaw 43 are the key interfaces for connecting to the external gas source. Connected to the gas source through a conduit, the vent holes allow compressed air to enter the pneumatic components inside the flexible jaw. As Figure 3 and Figure 5 shown, when positive-pressure compressed air is introduced, the air bag or pneumatic chamber expands, pushing the flexible jaw to open and realizing the release of the clothing; while when negative-pressure compressed air is introduced, the air bag or pneumatic chamber contracts, and the flexible jaw tightly holds the clothing to complete the grasping action. The pressure of the positive-pressure compressed air is 30 - 70 kPa, and the pressure of the negative-pressure compressed air is 60 - 100 kPa. More preferably, the pressure of the positive-pressure compressed air is 50 kPa, and the pressure of the negative-pressure compressed air is 80 kPa.

[0072] In addition, the pneumatic control system preferably also includes various valves, such as directional control valves, flow control valves and pressure control valves, which work together to optimize the performance of the pneumatic soft claw. For example, a one-way valve prevents the compressed air from flowing in reverse, while a flow proportional valve allows the output flow to be continuously adjusted according to an electrical signal, thereby improving the response speed and control accuracy of the system.

[0073] In practical applications, the gripping ability, adaptability and operating accuracy of the pneumatic soft gripper 43 are achieved through a carefully designed pneumatic control system. This system not only provides efficient and stable power transmission, but also achieves fine control of the soft gripper action through the coordinated work of various control elements, meeting the complex requirements of opening the collar f1 of the clothing and grabbing the clothing f in the automated hanging operation.

[0074] More preferably, intelligent sensors, such as force sensors or distance sensors, are integrated into the first grasping device 101 and the second grasping device 102 to achieve real-time monitoring and adjustment of grasping force and position, thereby improving the accuracy and safety of the operation.

[0075] In addition, a wireless communication module, such as Wi-Fi or Bluetooth, is provided on the collar opening mechanism 100 so that it can receive operation instructions remotely or be integrated with a smart home system to achieve more convenient operation and automated control.

[0076] Preferably, the "finger" portion of the flexible gripper is made of a flexible material such as polymer silicone, and is bent and deformed by inflation, thereby adaptively covering the target object to achieve grasping.

[0077] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. "First" and "second" are only for the purpose of making the description easier to understand, without any other directional meaning, and cannot be used as a limitation on the present utility model.

[0078] The utility model provides a collar opening mechanism for hanging clothes. The principle and implementation method of the utility model are described in this article using specific examples. The above examples are only used to help understand the utility model and its core idea. It should be pointed out that for ordinary technicians in this technical field, the utility model can be improved and modified in some ways without departing from the principle of the utility model, and these improvements and modifications also fall within the protection scope of the claims of the utility model.
