Description

Technical Field

[0001] The present application relates to the technical field of material strip winding, and in particular to a winding needle driving mechanism, a winding head and a winding device. Background Art

[0002] The production of multiple products involves the automatic winding of material strips, such as the automatic winding of thin films and the automatic winding of battery cells. Usually, multiple sets of winding needle assemblies are set on the winding head, so that there are winding needle assemblies working at different stations to improve efficiency. For each winding needle assembly, it is necessary to pass through multiple stations in sequence and complete the preset winding action at each station. In the prior art, each winding needle assembly is equipped with a winding power, that is, the winding needle assembly and the winding power correspond one to one. The number of winding powers set is large, resulting in a complicated winding head structure, large space occupation, large inertia and high energy consumption when switching the station of the winding needle assembly, and because the winding power and the line move with it, the overall speed is affected, which is easy to reduce the processing efficiency; on the other hand, due to space limitations, the specifications of the winding power cannot be large, but the power required by each station is different. Using the same winding power to meet the power requirements of each station either has insufficient power devices, which reduces efficiency, or has too large specifications, resulting in unnecessary costs and energy consumption.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Please refer to the attached Figure 1-11 , an embodiment of the present application provides a winding needle drive mechanism for driving the winding needles on each station to rotate and complete the required winding operation. The winding needle drive mechanism includes a frame 30, a movable seat 31, a drive module and a winding needle assembly 10. The frame 30 is fixedly arranged, and the movable seat 31 is movably arranged on the frame 30, and a plurality of stations are formed on the moving path, such as a winding station, a gluing station and a unloading station, etc. The winding needle assembly 10 is arranged on the movable seat 31, and passes through each station in sequence as the movable seat 31 moves to complete the processing, for example, it moves from the winding station to the gluing station and then moves to the unloading station to complete the processing of a material strip, and then moves from the unloading station to the winding station to restart the next cycle. The movable seat 31 can be either translational or rotational. To facilitate recycling, in a preferred embodiment, the movable seat 31 can be as follows Figure 1 The turntable structure shown is rotatably arranged on the frame 30. A plurality of workstations are arranged circumferentially. There can be one or more winding needle assemblies 10. In a preferred embodiment, the number of winding needle assemblies 10 is the same as the number of workstations, so that each workstation has a winding needle assembly 10 working, thereby improving the workstation efficiency.

[0043] The winding needle assembly 10 is rotatably arranged on the movable seat 31 so as to be able to rotate at each workstation, for example, the winding needle is used to wind the material strip at the winding station, and the wound material roll is rotated at the gluing station, etc. The driving module is used to drive the winding needle assembly 10 to rotate. In the present application, the driving module includes a plurality of power devices 20, and the plurality of power devices 20 are fixedly arranged, and one power device 20 corresponds to one workstation, that is, each workstation has an exclusive fixed power device 20, forming an exclusive workstation power. For example, the power device 20 corresponding to the winding station can be called the winding station power 20A, the power device 20 corresponding to the gluing station can be called the gluing station power 20B, and the power device 20 corresponding to the unloading station can be called the unloading station power 20C.

[0044] The winding needle assembly 10 and the power device 20 are not fixedly connected, nor are they one-to-one, but are switched. The power device 20 is one-to-one with the workstation, and the winding needle assembly 10 is rotatably set on the moving seat 31. In the process of passing through each workstation in sequence with the moving seat 31, the power device 20 for power transmission will be switched, that is, when moving to any workstation, it will be connected to the exclusive workstation power transmission of the workstation, and will be driven by the exclusive workstation power of the workstation to rotate. When switching workstations, it will be separated from the exclusive workstation power transmission of the workstation (that is, the transmission is interrupted), and only the winding needle assembly 10 and the transmission assembly will move with the moving seat 31. After moving to the next workstation, it will be reconnected to the exclusive workstation power transmission of the next workstation. For example, when the winding needle assembly 10 is in the winding station, it is connected to the winding station power 20A by transmission, and is driven by the winding station power 20A to rotate. When the winding needle assembly 10 completes the rotation operation of the winding station, it stops rotating and is separated from the winding station power 20A by transmission, and then moves to the gluing station with the movement of the moving seat 31. The winding needle assembly 10 in the gluing station is connected to the gluing station power 20B by transmission, establishes a power transmission path, and is driven by the gluing station power 20B to rotate. When the winding needle assembly 10 completes the processing of the gluing station, it stops rotating and is separated from the gluing station power 20B by transmission, and then moves to the unloading station and is connected to the unloading station power 20C by transmission, and is driven by the unloading station power 20C to rotate, completing the rotation operation of the unloading station. In this way, each time the winding needle assembly 10 switches a station, a power device 20 for transmitting power to it will be switched.

[0045] In other words, each workstation has an exclusive fixed power device 20, which is only used to drive the winding needle assembly 10 at the workstation to rotate, that is, after any winding needle assembly 10 moves to the workstation, the exclusive power of the workstation will drive the winding needle assembly 10 at the workstation to rotate. When the winding needle assembly 10 moves away, the power transmission with the winding needle assembly 10 is switched, and the power transmission is established with the next winding needle assembly 10 moved to the workstation to drive the newly moved winding needle assembly 10 to rotate.

[0046] With such an arrangement, on the one hand, each power device 20 is fixed on the frame 30 and does not need to follow the frequent movement of the winding needle assembly 10, which is convenient for line layout and simplifies the structural arrangement on the moving seat 31, reducing the moving inertia and energy consumption of the moving seat 31, and facilitating the improvement of the moving stability and moving speed of the moving seat 31, thereby improving the processing efficiency; on the other hand, each power device 20 is no longer arranged one-to-one with the winding needle assembly 10, but is exclusively matched and arranged according to the requirements of the workstation, becoming the exclusive power required by the workstation, with appropriate specifications to meet the power requirements of each workstation, ensuring processing efficiency, and each power device 20 does not need to be set as a large-specification power, which reduces the space volume, saves costs, and improves the compactness and reliability of the overall structure. There is no problem that each power device 20 needs to reduce its specifications due to space limitations, resulting in insufficient power at some high-power demand workstations and reducing processing efficiency.

[0047] It can be seen that the winding needle drive mechanism provided in the present application separates the drive module from the moving seat 31, effectively reducing the overall structural complexity, overall mass and rotational inertia of the moving seat 31, significantly reducing energy consumption, reducing volume, and improving movement stability, thereby improving processing efficiency; and the power device 20 is not one-to-one with the winding needle assembly 10, but is fixed one-to-one with the workstation, realizing a non-fixed drive mode, changing the traditional fixed transmission in the prior art, and realizing fixed-point drive, matching and meeting the power requirements of each workstation, with better performance and more in line with the core concept of mechanical design. All winding needle assemblies 10 are powered by a set of drive modules to achieve power drives of different workstation specifications; the entire winding needle drive mechanism has a more reasonable structural layout, a compact overall structure, high stability and high reliability.

[0048] Usually, the power required at the winding station is large and the winding speed is high. The winding station power 20A can be set as a large-sized power device 20. However, at the gluing station and the unloading station, the power required is small and the winding speed requirement is low. The gluing station power 20B and the unloading station power 20C can both use a smaller-sized power device 20, for example, Figure 1 As shown, power devices 20 of different specifications can be arranged in a staggered manner, occupying less space and being convenient for dispersed arrangement in dispersed spaces, making the overall structure more neat and compact.

[0049] The power device 20 of each of the above-mentioned workstations can be an electric motor, a cylinder, a hydraulic cylinder, a motor, etc. Based on the output being a rotational motion, an electric motor is preferred.

[0050] In order to realize the power switching of the winding needle assembly 10, or in other words, to realize the power transmission of each dedicated workstation power and any winding needle assembly 10 moved to the workstation, the power device 20, i.e., the dedicated workstation power, is provided with a first transmission part connected to the power output shaft, and the winding needle assembly 10 is provided with a second transmission part, which is connected to the reel 13 of the winding needle assembly 10 (the winding needle assembly 10 includes the reel 13 and the winding needle located in the reel 13, and the reel 13 drives the winding needle to rotate) and can drive the reel 13 to rotate. At the same time, the second transmission part can be connected or separated from the first transmission part on the power device 20, that is, it can be connected to the power device 20 for power transmission, and can also be separated from the power device 20 for power transmission, so as to realize the power switching of the winding needle assembly 10. The first transmission parts on all power devices 20 can have the same structure or different structures, for example, there are two or more different component structures, and the same is true for each second transmission part.

[0051] The first transmission part and the second transmission part may be a transmission shaft, a transmission wheel, or other transmission components, or may include both a transmission shaft and a transmission wheel.

[0052] For example, in some embodiments, the first transmission part includes a first transmission wheel 25 connected to the power output shaft of the power device 20, and the second transmission part includes a second transmission wheel 15 connected to the reel 13 and capable of driving the reel 13 to rotate. As the winding needle assembly 10 moves, the first transmission wheel 25 and the second transmission wheel 15 are close to each other, and power can be transmitted through magnetic force or friction. When the winding needle assembly 10 is removed from the workstation, the two transmission wheels are separated from each other, and the power transmission with the power device 20 of the workstation can be disconnected.

[0053] For example, the first transmission wheel 25 and the second transmission wheel 15 are both magnetic wheels, and the two form a magnetic wheel group that can transmit power. When the winding needle assembly 10 moves to the work station, the two magnetic wheels approach each other, and through magnetic repulsion, the rotating magnetic wheel set on the power device 20 will drive the magnetic wheel on the approaching winding needle assembly 10 to rotate, thereby driving the reel 13 to rotate. Alternatively, the first transmission wheel 25 and the second transmission wheel 15 form a friction wheel group. When the winding needle assembly 10 moves to the work station, the second transmission wheel 15 and the first transmission wheel 25 are against each other, and the rotating first transmission wheel 25 drives the second transmission wheel 15 to rotate through friction, thereby driving the reel 13 to rotate. In this way, the transmission structure is simple, which is convenient for power switching between the winding needle assembly 10 and the power device 20. The first transmission part of each power device 20 can be set as a transmission wheel.

[0054] Alternatively, in some embodiments, the first transmission part includes a first transmission shaft 23 and a first clutch 24. The first transmission shaft 23 is in transmission connection with the power output shaft of the power device 20, or can be formed by the power output shaft itself. The first clutch 24 is configured to connect or disconnect the first transmission shaft 23 and the second transmission shaft 14. The second transmission shaft 14 is in transmission connection with the reel 13 of the winding needle assembly 10. For example, Figure 2 As shown, the second transmission shaft 14 is rotatably arranged on the moving seat 31, the reel 13 is provided with a first gear 16, and the second transmission shaft 14 is provided with a second gear 17. The first gear 16 and the second gear 17 are meshed and connected, so that the second transmission shaft 14 is always connected to the reel 13. At the workstation, the first transmission shaft 23 and the second transmission shaft 14 are coaxial, and are connected or separated through the first clutch 24. The first clutch 24 has an engaged state and a separated state. For example, when the first clutch 24 is closed and switched to the engaged state, the first transmission shaft 23 and the second transmission shaft 14 can be connected, so that power can be transmitted from the power device 20 to the reel 13 in sequence through the first transmission shaft 23-first clutch 24-second transmission shaft 14, driving the winding needle assembly 10 to rotate. Disconnecting the first clutch 24, that is, switching the first clutch 24 to the separated state, will separate the first transmission shaft 23 and the second transmission shaft 14, interrupting the power transmission.

[0055] The first clutch 24 may be an electromagnetic clutch, other types of clutches, an electromagnetic lock, a hydraulic lock or a pneumatic lock, or a mechanical component that can meet the engagement and separation operations. Specifically, the first clutch 24 includes a first clutch component connected to the first transmission shaft 23 and a power source component connected to the first clutch component. The power source component may be a motor, a cylinder, a hydraulic cylinder, a motor or an electromagnetic coil, and the first clutch component is driven to be connected to or separated from the second transmission shaft 14 by means of electric control, pneumatic control, hydraulic control or electromagnetic control.

[0056] The first clutch component can be an electromagnetic component that can generate magnetism when powered on, and the second transmission shaft 24 is provided with a clutch part that can be attracted to the first clutch component in the axial direction (for example, formed by the end of the second transmission shaft 14 close to the first transmission shaft 23); the first clutch component generates magnetism after power is supplied and can attract the clutch part on the second transmission shaft 14, and the material of the clutch part is an electromagnetic adsorption material such as magnet or iron. Such as an electromagnetic clutch or an electromagnetic lock.

[0057] Or, the first clutch component is a clamping claw or a clamping block, which can clamp or hold the second transmission shaft 24 to drive the second transmission shaft 24 to rotate in the first state, and release it in the second state to move the second transmission shaft 24 away. Such as a hydraulic lock or a pneumatic lock structure (including a power source and an openable and closable locking claw, the base of the locking claw is connected to the first transmission shaft 23, and the claw is used to clamp or release the second transmission shaft 14, thereby transmitting power or cutting off power transmission).

[0058] Alternatively, one end of the first clutch member is connected to the first transmission shaft 23, is telescopically arranged, and can be engaged with the clutch portion on the second transmission shaft 24 to drive the second transmission shaft 24 to rotate.

[0059] Or, one end of the first clutch component is a fixed end, which is fixedly connected to the first transmission shaft 23, and the other end is a telescopic end, which can be telescoped under the drive of the power source. The telescopic end can be engaged with the clutch part on the second transmission shaft 14, such as one has a plug-in protrusion and the other has a groove. After plugging, they abut against the side wall of the groove to form a circumferential limit. When the first clutch component rotates with the first transmission shaft 23, it will drive the second transmission shaft 14 to rotate.

[0060] The first transmission parts on each power device 20 may have the same structure or different structures. Figure 1 and Figure 2 As shown, among the multiple power devices 20, the first transmission part on some of the power devices 20 is provided with a first transmission shaft 23 and a first clutch 24, and the first transmission part on other power devices 20 is provided with a first transmission wheel 25. Each second transmission part includes a second transmission shaft 14 and a second transmission wheel 15, and the second transmission shaft 14 and the second transmission wheel 15 are both connected to the reel 13 of the needle winding assembly 10, and can independently drive the reel 13 to rotate. That is, each needle winding assembly 10 is equipped with a second transmission shaft 14 and a second transmission wheel 15. When the needle winding assembly 10 moves to a station with a first transmission shaft 23, the second transmission shaft 14 connected thereto moves to a position coaxial with the first transmission shaft 23 of the station and matching with the first clutch 24 on the first transmission shaft 23. The first clutch 24 of the station is closed to realize the power transmission between the needle winding assembly 10 and the power device 20 of the station, and the reel 13 is driven to rotate by the second transmission shaft 14. When the winding needle assembly 10 moves to the station with the first transmission wheel 25, the first clutch 24 is in a disengaged state, and the power device 20 at the station drives the winding drum 13 to rotate through the first transmission wheel 25 and the second transmission wheel 15. That is, the winding needle assembly 10 transmits or disconnects power with the above-mentioned part of the power device 20 through the second transmission shaft 14, and connects or disconnects with the first transmission wheel 25 through the second transmission wheel 15, thereby realizing power transmission or disconnection with other power devices 20.

[0061] In an embodiment in which the first transmission portion includes or is the first transmission shaft 23, when the winding needle assembly 10 switches power, if the second transmission shaft 14 also needs to switch the first transmission shaft 23 connected thereto, for example, after the second transmission shaft 14 of the winding needle assembly 10 is connected to the first transmission shaft 23 of the winding station power 20A, when it moves to the next station, its second transmission shaft 14 needs to be connected to the first transmission shaft 23 of the next station, that is, every time the second transmission shaft 14 switches a station with the winding needle assembly 10, a first clutch 24 connected thereto needs to be replaced, which places high requirements on the structural setting of the first clutch 24 and the structure is relatively complicated.

[0062] Therefore, in a preferred embodiment provided by the present application, only one power device 20 has a first transmission part configured as a first transmission shaft 23 and a first clutch 24, and the first transmission parts of the remaining power devices 20 are non-shaft transmission structures, such as first transmission wheels 25. The second transmission parts of each winding needle assembly 10 are provided with a second transmission shaft 14 and a second transmission wheel 15. At the same time, the power device 20 has multiple first transmission parts, the number of the first transmission parts is the same as the number of the winding needle assemblies 10, and the first transmission parts and the winding needle assemblies 10 are set one-to-one. The power device 20 is independently connected to each winding needle assembly 10 through multiple first transmission parts, and establishes an exclusive transmission structure and transmission path with each winding needle assembly 10. The second transmission shaft 14 of each winding needle assembly 10 is combined or separated with the corresponding exclusive first clutch 24 and the first transmission shaft 23. When the winding needle assembly 10 switches the workstation, the second transmission shaft 14 does not need to switch the first transmission shaft 23 connected to it, and the corresponding first clutch 24 only needs to be switched to the separated state, and the winding needle assembly 10 can transmit power to the power device 20 of the other workstation through the second transmission wheel 15. For the power device 20, there is no need to frequently switch the second transmission shaft 14 connected thereto. After the connection paths are established with each second transmission shaft 14 through multiple first transmission shafts 23, during the process of each winding needle assembly 10 circulating in the workstation, the power transmission of different paths can be exchanged by simply switching the state of the first clutch 24 on each path. That is, each winding needle assembly 10 always maintains a stable and exclusive transmission path. When a certain winding needle assembly 10 moves to the workstation, the corresponding transmission path is started and other transmission paths are cut off. In this way, the power of the winding needle assembly 10 can be cut off very conveniently, and the circulation drive of each winding needle assembly 10 by the power device 20 can also be realized very conveniently. The power device 20 and the winding needle assembly 10 do not need to replace the structural connection object, and the overall structure is simpler and more stable.

[0063] The power device 20 can be a winding station power 20A. Because the winding station power 20A has large specifications, high power, and a high output rotation rate, the power transmission through the shaft is more stable and the transmission is more effective. The following is a detailed description of the first transmission part on the winding station power 20A including the first transmission shaft 23 as an example. In this embodiment, the winding station power 20A has multiple groups of first transmission parts, that is, multiple groups of first transmission shafts 23 and first clutches 24, which are respectively connected to the second transmission shafts 14 of each winding needle assembly 10. Taking the figure as an example, the winding needle assembly 10 is provided with three groups, which are respectively recorded as the winding needle assembly 10A, the winding needle assembly 10B and the winding needle assembly 10C. The winding station power 20A is provided with three groups of first transmission parts, the first transmission part A includes the first transmission shaft 23A and the first clutch 24A, the first transmission part B includes the first transmission shaft 23B and the first clutch 24B, and the first transmission part C includes the first transmission shaft 23C and the first clutch 24C. The first transmission part A is connected to the second transmission shaft 14A of the winding needle assembly 10A, the first transmission part B is connected to the second transmission shaft 14B of the winding needle assembly 10B, and the first transmission part C is connected to the second transmission shaft 14C of the winding needle assembly 10C. Each set of winding needle assembly 10 and the transmission part forms an independent module, and the transmission part moves with the movement of the winding needle assembly 10.

[0064] During the rotation of each winding needle assembly 10, the first transmission part moves accordingly, but always maintains a transmission connection with the winding station power 20A. Figure 2 As shown, the movable seat 31 rotates and moves, and is a turntable structure. A sun gear 21 is provided on the power output shaft of the winding station power 20A, and planetary gears 22 are provided on each first transmission shaft 23. Each planetary gear 22 is meshed and connected with the sun gear 21. When the winding needle assembly 10 rotates, the first transmission part rotates with the corresponding winding needle assembly 10 around the power output shaft of the winding station power 20A, and maintains meshing connection with the power output shaft of the winding station power 20A.

[0065] When the needle winding assembly 10A rotates to the winding station, the first clutch 24B and C are in a separated state, the first clutch 24A switches to an engaged state, the first transmission shaft 23A and the second transmission shaft 14A are engaged and connected, and the winding station power 20A drives the needle winding assembly 10A to rotate. When it is necessary to switch the station, the first clutch 24A switches to a separated state, the first transmission shaft 23A and the second transmission shaft 14A are separated, the needle winding assembly 10A stops rotating, and then the moving seat 31 rotates, each needle winding assembly 10 and each transmission part rotates around the power output shaft of the winding station power 20A, and the corresponding setting of the transmission part is maintained. The needle winding assembly 10A moves to the gluing station, and the folding assembly C rotates to the winding station. The first clutch 24A and B remain separated, and the first clutch 24C switches to an engaged state, the first transmission shaft 23C and the second transmission shaft 14C are engaged and connected, and the winding station power 20A drives the needle winding assembly 10C to rotate. In this way, each winding needle assembly 10 rotates cyclically, and the winding station power 20A drives each winding needle assembly 10 to rotate on the winding station in turn.

[0066] Such an arrangement can ensure the stability and effectiveness of the power transmission of the power device 20 at the workstation where the required power is the largest, and ensure the rotation rate of the winding needle assembly 10 at the workstation, thereby avoiding affecting the processing efficiency.

[0067] The power devices 20 at other stations transmit power to the needle assembly 10 through transmission wheels or other transmission structures. For example, the power required by the gluing station and the unloading station is relatively small, and the required rotation speed of the needle assembly 10 is relatively small, so the first transmission part of the power 20B of the gluing station and the power 20C of the unloading station can be a transmission wheel structure. Figure 1 As shown, the power output shaft of the power 20B of the gluing station is provided with a first transmission wheel 25A, and the power output shaft of the power 20C of the unloading station is provided with a first transmission wheel 25B. When each winding assembly moves to the gluing station or the unloading station, its second transmission wheel 15 is close to or in contact with the first transmission wheel 25 to transmit power. When switching stations, the two transmission wheels can be directly separated. For example, during the workstation rotation, the winding needle assembly 10A moves to the gluing station, the winding needle assembly 10B moves to the unloading station, and the winding needle assembly 10C moves to the winding station. The winding station power 20A drives the second transmission shaft 14C to rotate through the first transmission part C, thereby driving the winding needle assembly 10C to rotate. The second transmission wheel 15A of the winding needle assembly 10A is close to the first transmission wheel 25A of the gluing station. The gluing station power 20B drives the winding needle assembly 10A to rotate. The second transmission wheel 15B of the winding needle assembly 10B is close to the first transmission wheel 25B of the unloading station. The unloading station power 20C drives the winding needle assembly 10B to rotate.

[0068] In other words, for the winding station, the winding station power 20A drives the winding needle assembly 10 of the winding station through the transmission path of multiple groups of first transmission shaft 23-first clutch 24-second transmission shaft 14-reel 13; for the gluing station and the unloading station, the power device 20 drives the winding needle assembly 10 on the respective stations in turn through the transmission path of the first transmission wheel 25-second transmission wheel 15-reel 13.

[0069] With such an arrangement, the entire drive module has a reasonable and concise structure, ensuring the stability and effectiveness of power transmission by each power device 20. At the same time, the structure for switching transmission between the winding needle assembly 10 and the power device 20 is streamlined and reasonable, which can simplify the switching process of the power transmission path, ensure the stability of the power transmission path switching, and improve the switching speed.

[0070] Of course, in other embodiments, the first transmission part of each power device 20 may be the first transmission shaft 23. In this way, each power device 20 is provided with a first transmission shaft 23, and each winding needle assembly 10 is driven by the first transmission shaft 23. That is, each first transmission shaft 23 and each second transmission shaft 14 need to be switched and connected.

[0071] For example, the winding station power 20A is provided with a first transmission shaft 23D and a first clutch 24D, the gluing station power 20B is provided with a first transmission shaft 23E and a first clutch 24E, and the unloading station power 20C is provided with a first transmission shaft 23F and a first clutch 24F. When the winding needle assembly 10A is in the winding station, the second transmission shaft 14A moves to a position coaxial with the first transmission shaft 23D, and the first clutch 24D connects the first transmission shaft 23D and the second transmission shaft 14A, so that the winding station power 20A drives the winding needle assembly 10A in the winding station to rotate. The same is true for the gluing station and the unloading station. The first clutch 24E connects the first transmission shaft 23E and the second transmission shaft 14B of the winding needle assembly 10B, and the first clutch 24F connects the first transmission shaft 23F and the second transmission shaft 14C of the winding needle assembly 10C.

[0072] When each winding needle assembly 10 switches the workstation, each first clutch 24 switches to the separation state, disconnecting the connection between the first transmission shaft 23 and the second transmission shaft 14 at each workstation. Then the moving seat 31 moves, and each second transmission shaft 14 moves to a position on the new workstation that is coaxial with the first transmission shaft 23 and matches the first clutch 24, so that the first clutch 24 at the new workstation can connect to the new second transmission shaft 14. For example, the winding needle assembly 10C moves to the winding workstation, the winding needle assembly 10A moves to the gluing workstation, and the winding needle assembly 10B moves to the unloading workstation. The first clutch 24E on the winding workstation power 20A engages with the second transmission shaft 14C of the winding needle assembly 10C, and the winding workstation power 20A drives the winding needle assembly 10C to rotate and perform winding rotation. The first clutch 24E on the gluing workstation power 20B engages with the second transmission shaft 14A, driving the winding needle assembly 10A at the gluing workstation to rotate. The first clutch member 24F of the unloading station power 20C is engaged with the second transmission shaft 14B to drive the winding needle assembly 10B to rotate for unloading.

[0073] The power devices 20 for driving the needle winding assembly 10 to rotate may be, but are not limited to, electric motors, air cylinders, hydraulic cylinders, motors, and the like.

[0074] When the winding needle assembly 10 is in the workstation flow, due to the disconnection with the power device 20, the winding needle assembly 10 is prone to rotation, shaking, swaying, etc., resulting in angular misalignment, which can easily lead to the problem that the actual position of the winding needle or the material roll deviates from the preset position at the workstation and cannot be processed smoothly. Therefore, in the embodiment of the present application, a self-locking assembly 50 is also included. The self-locking assembly 50 is used to lock the rotation of the winding needle assembly 10 and can be set one-to-one with the winding needle assembly 10. For example, it can be used to lock the reel 13, or it can be used to lock the second transmission shaft 14 connected to the reel 13. When the winding needle assembly 10 stops rotating and moves to another workstation, the self-locking assembly 50 locks the winding needle assembly 10, effectively preventing the winding needle assembly 10 from rotating, shaking, moving, and other movements that may easily lead to angular misalignment, thereby ensuring the position accuracy of the winding needle assembly 10, and completely eliminating the possibility of the winding needle assembly 10 rotating when switching workstations, thereby improving stability and processing efficiency, and avoiding the problem that the actual position of the winding needle or the winding needle loading roll deviates from the preset position at the workstation, resulting in smooth processing.

[0075] Specifically, the self-locking assembly 50 includes a locking power 51, a pushing member 52 and a locking member 53. The locking power 51 is fixedly connected to the movable seat 31. The pushing member 52 pushes the locking member 53 to move under the drive of the locking power 51, so that the locking member 53 locks the reel 13 or the second transmission shaft 14 of the winding needle assembly 10 to prevent the winding needle assembly 10 from rotating. The locking member 53 can be locked by tightening, pressing or inserting a limit. When the winding needle assembly 10 moves to the workstation and needs to be rotated, the locking member 53 is reset under the drive of the pushing member 52 or the reset member, and the reel 13 or the second transmission shaft 14 is released, and the self-locking assembly 50 is unlocked. The winding needle assembly 10 can be rotated under the drive of the power device 20 of the workstation.

[0076] like Figure 2 As shown, in some embodiments, the locking member 53 of the self-locking assembly 50 can be arranged on the second transmission shaft 14 to lock the second transmission shaft 14. Since the second transmission shaft 14 is always meshed and connected with the reel 13 through the gear structure, locking the second transmission shaft 14 can lock the reel 13 to prevent the winding needle assembly 10 from rotating. In this way, the winding needle assembly 10 is still a simple independent module, which is convenient for independent replacement. The self-locking assembly 50 and the second transmission shaft 14 are both arranged on one side of the winding needle assembly 10 as matching parts. Compared with the reel 13, the second transmission shaft 14 has a smaller diameter, and the specifications and volume of the self-locking assembly 50 can also be smaller, which is convenient for layout. Of course, the self-locking assembly 50 can also be arranged at the winding needle assembly 10 to lock the reel 13. The following is uniformly explained as the self-locking assembly 50 being arranged at the second transmission shaft 14.

[0077] If the resetting of the locking member 53 is achieved by the pushing member 52, the locking member 53 is connected to the pushing member 52, and is driven by the pushing member 52 to move back and forth, and the needle winding assembly 10 is locked or unlocked. If the self-locking assembly 50 includes a reset member, the resetting of the locking member 53 is achieved by the reset member, and the locking member 53 and the pushing member 52 can be separately arranged. When the pushing member 52 pushes the locking member 53 to move and lock, the reset member produces elastic deformation. When the pushing member 52 is reset and moved back, the reset member recovers and drives the locking member 53 to reset and release the lock. For example, the reset member can be a spring. The spring is arranged on the moving path of the locking member 53, and one end is against the locking member 53. When the locking member 53 is locked and moved, the spring is compressed. Therefore, when the pushing member 52 that pushes the locking member 53 is reset and moved back, the spring pushes the locking member 53 to reset.

[0078] like Figure 3 As shown, in some embodiments, the self-locking assembly 50 further includes a guide structure, which guides the movement of the locking member 53 to prevent the locking member 53 from tilting, and is particularly suitable for embodiments in which the pushing member 52 and the locking member 53 are separately arranged.

[0079] The guide structure may include a guide column, and the locking member 53 is slidably mounted on the guide column. When a spring is provided, the spring may be mounted on the guide column and located on one side of the locking member 53, and the other end of the spring may abut against a boss on the guide column. In this way, the entire self-locking assembly 50 has a simple structure, a small volume, and is easy to arrange. The guide structure may also include a guide slot 522, and a part or the entirety of the locking member 53 is slidably mounted in the guide slot 522.

[0080] The locking member 53 locks the second transmission shaft 14 by tightening, pressing or embedding. If the locking member 53 and the second transmission shaft 14 are embedded, one of them has a protrusion, and the other has a groove for the protrusion to be embedded. When the locking member 53 is close to the second transmission shaft 14, the protrusion is embedded in the groove to achieve locking. If the locking member 53 is tightened, the locking member 53 is at least two clamping blocks 532 around the outer circumference of the second transmission shaft 14. The pusher 52 moves and pushes the clamping blocks 532 to get closer to tighten the second transmission shaft 14. If the locking member 53 is pressed, the locking member 53 will press against the second transmission shaft 14, and the second transmission shaft 14 will be locked by friction to achieve locking.

[0081] When the pushing member 52 and the locking member 53 are separately arranged, in order to facilitate the movement of the locking member 53, in some embodiments, a first wedge surface is provided on the pushing member 52, and a second wedge surface is provided on the locking member 53. The pushing member 52 moves to cause the first wedge surface to push the second wedge surface, thereby driving the locking member 53 to move.

[0082] For example Figure 2 and Figure 3 As shown, in some embodiments, the locking member 53 is sleeved on the second transmission shaft 14, and when the pushing member 52 translates in the direction close to the second transmission shaft 14, it will push the locking member 53 to move along the axial direction of the second transmission shaft 14, thereby locking the second transmission shaft 14 or the reel 13. For example, the hole wall of the through hole of the locking member 53 through which the second transmission shaft 14 passes forms an inner conical surface 531, and a boss is provided on the second transmission shaft 14, and the outer wall of the boss forms an outer conical surface. The axial movement of the locking member 53 along the second transmission shaft 14 can make the inner conical surface 531 press against the outer conical surface, locking the second transmission shaft 14 or the reel 13, thereby achieving the purpose of braking and locking the needle winding assembly 10. Alternatively, the second transmission shaft 14 has a boss, and one of the boss and the locking member 53 has a protrusion, and the other has a groove for the protrusion to be embedded. When the locking member 53 moves along the axial direction of the second transmission shaft 14, the protrusion is embedded in the groove, thereby locking the second transmission shaft 14.

[0083] like Figure 4As shown, in some embodiments, the locking member 53 includes at least two clamping blocks 532 arranged around the second transmission shaft 14, a slide groove 522 is arranged on the pushing member 52, and the two groove side walls are both first wedge-shaped surfaces, each clamping block 532 is slidably arranged in the slide groove 522, and the outer side wall away from the second transmission shaft 14 forms a second wedge-shaped surface, and abuts against the first wedge-shaped surface. The slide groove 522 on the pushing member 52 gradually increases in size along the direction approaching the locking member 53, similar to a V-shaped groove. When the pushing member 52 moves so that the first wedge-shaped surface pushes against the second wedge-shaped surface, each clamping block 532 gradually approaches the pushing member 52, and is squeezed by the gradually shrinking slide groove 522, so that each clamping block 532 can be brought close to each other and tighten the second transmission shaft 14.

[0084] like Figure 5 As shown, in some other embodiments, the locking member 53 includes at least two clamping blocks 532 arranged around the second transmission shaft 14, the pushing member 52 is sleeved on the second transmission shaft 14, and the pushing member 52 is provided with an arc track 523 gradually approaching the second transmission shaft 14, the arc track 523 and the clamping blocks 532 are arranged one-to-one, and the clamping blocks 532 are slidably connected to the arc track 523. When the pushing member 52 is rotated in a clockwise or counterclockwise direction ( Figure 5 The rotation of the push member 52 (in the counterclockwise direction) will drive the clamping block 532 to move along the arc track 523, so that each clamping block 532 is close to each other and tightens the second transmission shaft 14 to achieve locking. When the push member 52 rotates in the opposite direction, it will drive the clamping block 532 away from the second transmission shaft 14 to release the lock.

[0085] Specifically, the arc track 523 can be an arc groove, a sliding column is fixedly connected to the clamp block 532, one end of the sliding column extends into the arc groove so that the clamp block 532 can be slidably connected to the arc groove. The arc track 523 can also be an arc slide rail, a slider is provided on the slide rail, and the clamp block 532 is fixedly connected to the slider and can move along the arc slide rail.

[0086] The locking power 51 that drives the pusher 52 to move can be a motor, a cylinder, a motor, etc., depending on the specific embodiment. The pusher 52 can be a block or a ring, depending on the specific embodiment. Of course, when the pusher 52 pushes the locking member 53, in some embodiments, it will move toward the direction close to the second transmission shaft 14. In such embodiments, the pusher 52 can be provided with an avoidance groove arranged along the moving direction and used for the second transmission shaft 14 to move into, so as to avoid the second transmission shaft 14.

[0087] In addition to the above embodiments, the self-locking component 50 can also be formed by a hydraulic lock or a pneumatic lock (including a power source and a lock claw that can be opened and closed). Alternatively, in some other embodiments, the self-locking component 50 is an electromagnetic structure, including a power supply and a locking member 53. The locking member 53 is an electromagnetic member that can adsorb the second transmission shaft 14. The second transmission shaft 14 has a locking portion. The material of the locking portion is an electromagnetic adsorption material that can adsorb the electromagnetic member, such as magnet or iron. The locking portion is formed by a part of the second transmission shaft 14 or an adsorption member connected to the second transmission shaft 14. When the power supply changes on and off, the locking member 53 adsorbs the locking portion of the second transmission shaft 14 and holds the second transmission shaft 14 to achieve locking.

[0088] The embodiment of the present application also provides a winding head, Figure 7-9 As shown, it includes a needle insertion and extraction mechanism and a winding needle driving mechanism. The needle insertion and extraction mechanism is used to pull the winding needle out of the reel 13 to wind the material strip, and is used to push the winding needle back to the reel 13 to unload the material roll. The winding needle driving mechanism is the winding needle driving mechanism described in any of the above embodiments. The winding head has the above-mentioned fixed-point driving structure, which has the advantages of simple structure, high stability, high processing rate, etc. The derivation of this beneficial effect will not be repeated.

[0089] The winding needle in the winding drum 13 of the winding needle assembly 10 includes two needle bodies, which are called the first half needle 11 and the second half needle 12. The first half needle 11 and the second half needle 12 can both enter and exit the winding drum 13. At the winding station, the second half needle 12 is in an extended state, and the material tape conveying mechanism delivers the material tape to the second half needle 12, and then extends the first half needle 11 to clamp the material tape between the two half needles, and then the winding can be carried out; at the unloading station, first pull back the first half needle 11, and then pull back the second half needle 12 to complete the unloading of the material roll, and after the unloading is completed, the second half needle 12 is pushed out. In this way, when the winding needle assembly moves to the winding station, the second half needle is in an extended state, and the first half needle is located in the winding drum.

[0090] In the prior art, in order to realize the independent sliding of the two half needles, three sets of independent needle plugging and pulling assemblies are usually provided. Two needle plugging and pulling assemblies are provided at the blanking station to respectively perform plugging and pulling operations on the two half needles of the winding needle assembly 10 located at the blanking station (i.e., one first pulls out the first half needle 11, and the other then pulls out the second half needle 12, and then pushes out the second half needle 12 after the blanking is completed), and the other needle plugging and pulling assemblies are provided at the winding station to perform the needle plugging operation on the first half needle 11 of the winding needle assembly 10 located at the winding station (i.e., push the first half needle 11 out of the reel 13). However, the three sets of independent needle plugging and pulling assemblies require three sets of servo control systems and three sets of plugging and pulling structures, which makes the entire winding equipment structure complicated, occupies a large space, and consumes a large amount of energy, which is not conducive to cost control.

[0091] In the embodiments of the present application, Fig. 9As shown, the needle plugging and pulling mechanism includes a bearing seat 49, a first plugging member 41, a second plugging member 42 and a plugging and pulling drive device 40. The first plugging member 41 and the second plugging member 42 are both movably arranged on the bearing seat 49, and the plugging and pulling drive device 40 is fixed on the bearing seat 49. The first plugging member 41 is used to insert the first half of the needle of the winding needle assembly 10 at the winding station, and to pull out the first half of the needle of the winding needle assembly 10 at the unloading station; the second plugging member 42 is used to pull out and insert the second half of the needle of the winding needle assembly 10 at the unloading station; the plugging and pulling drive device 40 drives the first plugging member 41 and the second plugging member 42 to move to insert and pull out the needle. In this way, the insertion operation of the first half of the needle at the winding station and the pulling out operation of the first half of the needle at the unloading station are realized by the same plugging member, which reduces a set of plugging and pulling structures, simplifies the complexity of the structure, and reduces space occupancy.

[0092] Furthermore, the plug-in drive device 40 includes one power member or two power members, rather than three power members. In this way, the structure can be further simplified and the space occupied can be reduced. When the pull-out drive device includes one power member, the power member is recorded as the first power member, and the plug-in drive device 40 is also provided with a transmission switching assembly. The same first power member is switched and connected with the first plug-in member 41 and the second plug-in member 42 through the transmission switching assembly to drive the first plug-in member 41 to move in the first state, and drive the second plug-in member 42 to move in the second state. In other words, the transmission switching assembly has an input end and two output ends, forming two transmission paths. In the first state, the first transmission path is turned on and the second transmission path is turned off. In the second state, the second transmission path is turned on and the first transmission path is turned off.

[0093] When the plug-in drive device 40 includes two power members, they are referred to as a second power member and a third power member. The second power member is transmission-connected to the first plug-in member 41 to drive the first plug-in member 41 to move, and the third power member is transmission-connected to the second plug-in member 42 to drive the second plug-in member 42 to move.

[0094] like Fig.11 As shown, the first half needle 11 and the second half needle 12 both have a needle portion and a tail portion (respectively located at Fig.11 The reel 13 has a first end and a second end, and the needle can extend and retract from the first end of the reel 13. Pushing the needle out of the reel is the needle insertion operation, and pulling the needle from the outside of the reel back into the reel is the needle withdrawal operation. The tail is located at the second end of the reel 13, and the needle can be extended into and retracted from the first end of the reel 13 by operating the tail. Based on the above structure, it can be seen that the axial directions of the reel 13, the first half needle 11, and the second half needle 12 are all the axial directions of the winding needle. The first plug-in component 41 and the second plug-in component 42 are both located at the second end of the reel 13, and the needle insertion operation is performed close to the reel, and the needle withdrawal operation is performed away from the reel 13.

[0095] The bearing seat 49 is also provided with two transmission structures, which are denoted as the first transmission structure and the second transmission structure. The plug-in drive device 40 is respectively connected to the first plug-in member 41 and the second plug-in member 42 through the two transmission structures. The first transmission structure and the second transmission structure can be linear transmission structures, such as a screw nut structure, a transmission belt structure, a gear rack structure, a crank slider structure 46, etc., or a rocker structure.

[0096] The first plugging member 41 includes a first base body, which is connected to the output end of the transmission switching assembly or the power member through the first transmission structure. The plugging drive device 40 drives the first plugging member 41 to reciprocate, that is, to move closer to or away from the reel to perform the pin insertion and pin removal operations.

[0097] For example, the output end of the transmission switching assembly or the power member is connected to the first base through the rocker structure, and the rocker in the rocker structure swings to drive the first base to approach and move away from the reel along an arc path. For another example, the output end is connected to the first base through the crank slider structure 46, and the slider in the crank slider structure 46 reciprocates linearly to drive the first base to reciprocate in the axial direction of the reel. In this way, the movement direction of the first base is consistent with the movement direction of the first half needle, which is conducive to reducing the movement path, saving energy consumption, and improving the stability and safety of the needle insertion and removal operations.

[0098] The second plug-in member 42 includes a second base body, which is connected to the output end of the transmission switching assembly or the power member through a second transmission structure. The plug-in drive device 40 drives the second plug-in member 42 to reciprocate, that is, to approach or move away from the reel to insert and remove the needle. Similarly, the reciprocating movement of the second plug-in member 42 can be a linear reciprocating displacement, or it can be reciprocatingly approaching or moving away from the reel along an arc path.

[0099] In the embodiment of the present application, it is preferred that the first plug-in component 41 and the second plug-in component 42 both move back and forth in a straight line along the axial direction of the reel. Then, a first guide structure 47 may also be provided, and two first guide structures 47 are provided to guide the first plug-in component 41 and the second plug-in component 42 respectively to ensure the accuracy of the linear movement. Specifically, the first guide structure 47 includes a plurality of first guide rods, the first guide rods are connected to the bearing seat 49, and the extension direction is parallel to the axial direction of the reel 13, and the first base is slidably connected to the first guide rods to guide the first base in the axial direction of the reel 13.

[0100] Specifically, the two output ends of the transmission switching assembly are two second clutch members 48, or two one-way bearing structures with opposite transmission directions, or two ratchet structures with opposite transmission directions. The two output ends are transmission-connected to the first plug-in member 41 and the second plug-in member 42 respectively.

[0101] The second clutch 48 is a structure similar to the first clutch, and can be connected or separated with the first plug-in 41 or the second plug-in 42 to transmit power or stop power transmission. That is, the structure of the second clutch 48 is the same as that of the first clutch, and can be various implementation structures of the first clutch listed above, such as electromagnetic clutch, hydraulic lock, pneumatic lock, electromagnetic lock, mechanical component capable of interlocking connection, etc., while the first plug-in 41 and the second plug-in 42 are equivalent to the second transmission shaft, or the input end of the first transmission structure and the input end of the second transmission structure are equivalent to the second transmission shaft, so the composition and structure of the second clutch 48 will not be repeated here.

[0102] On the basis that both the first transmission structure and the second transmission structure include a crank slider structure 46 and a first guide structure 47, the transmission switching assembly can be a one-way bearing structure or a ratchet structure with two opposite transmission directions. The input ends of the two one-way bearing structures or ratchet structures with opposite transmission directions are connected to the first power member, and the output ends are respectively connected to the input ends of the first transmission structure and the second transmission structure. Both the one-way bearing and the ratchet are one-way transmission structures. The transmission directions of the two one-way bearing structures or ratchet structures are opposite. When the first driving member rotates forward or reverse, one of them can transmit power, while the other cannot transmit power. In this way, by controlling the forward and reverse rotation of the first power member, the switching of the first state and the second state of the transmission switching assembly can be realized without the need for an external power supply, which is conducive to simplifying the structure.

[0103] When the plug-in drive device 40 includes a second power member and a third power member, the second power member is transmission-connected to the first plug-in member 41 through the first transmission structure, and the third power member is transmission-connected to the second plug-in member 42 through the second transmission structure.

[0104] The first plug-in and pull-out member 41 can perform the pin insertion and pin pull-out operations through the same structure or different structures. For example, the first plug-in pin inserts the first half pin at the winding station through a structure, and performs the pin pull-out operation on the first half pin at the blanking station. Since the two first half pins are at the winding station and the blanking station respectively, when the same structure is used, the structure needs to be switched in two positions or two postures to correspond to the two first half pins at different stations respectively, thereby realizing the corresponding operation. For example, the first plug-in member 41 includes a first plug-in structure provided on the first substrate, the first plug-in structure having a pushing surface for pushing the first half needle on the winding station, and also having a connecting portion for connecting to the first half needle on the unloading station. When the first plug-in member 41 approaches the reel, the pushing surface of the first plug-in structure abuts against the first half needle on the winding station, pushing the first half needle to move, and pushing the first half needle out of the reel of the winding needle assembly 10 on the winding station, thereby realizing the needle insertion operation of the first half needle of the winding station, and then the first plug-in structure rotates or moves a certain distance toward the first half needle of the unloading station, so that the connecting portion is embedded in the push-pull groove 101 at the tail end of the first half needle of the unloading station, and then the first plug-in member 41 moves in a direction away from the reel, which will drive the first half needle of the unloading station back to the reel of the winding needle assembly 10 on the unloading station, thereby realizing the needle pulling operation of the first half needle of the unloading station.

[0105] Or, the first plug-in member 41 includes a pin insertion structure 43 and a pin pulling structure 44. Since the two first half pins are respectively located at the winding station and the unloading station, the two first half pins are operated separately by the pin insertion structure 43 and the pin pulling structure 44. The pin insertion structure 43 first completes the pin insertion operation on the first half pin at the winding station, and then the pin pulling structure 44 completes the pin pulling operation on the first half pin at the unloading station. Interference can be avoided by the alternating actions of the pin insertion structure 43 and the pin pulling structure 44. For example, in the axial direction of the reel 13, the position of the pin insertion structure 43 is opposite to the first half pin 11 of the winding pin at the winding station, and the position of the pin pulling structure 44 is opposite to the first half pin 11 of the winding pin at the unloading station. In the process of the first plug-in member 41 approaching the reel 13, the pin insertion structure 43 pushes the first half pin 11 of the winding station to move out of the reel on the winding station, and at the same time, the pin pulling structure 44 also approaches the first half pin of the unloading station. When the needle insertion structure 43 moves into place, the needle insertion operation is completed, and at the same time, the needle pulling structure 44 is connected to the first half needle 11 at the unloading station; then, the first plug-in member 41 moves away from the reel 13, the needle insertion structure 43 separates from the first half needle 11 at the winding station, and the needle pulling structure 44 drives the first half needle 11 at the unloading station to move in a direction away from the reel, and performs the needle pulling operation on the first half needle 11 at the unloading station.

[0106] Of course, in some other solutions, the first plug member 41 may also be configured in other forms, such as Fig.11As shown, the first plug-in member 41 may only include a pin insertion structure 43 and a pin pulling structure 44, and the first base body is omitted. The pin insertion structure 43 and the pin pulling structure 44 are respectively connected to the transmission switching assembly through a gear rack structure. The gears of the two gear rack structures are meshed, so that the driving member transmits power to one of the gears of the gear rack structures through the transmission switching assembly, thereby driving the racks of the two gear rack structures to synchronously displace. The pin insertion structure 43 and the pin pulling structure 44 are respectively connected to the racks of the two gear rack structures, so that the pin insertion structure 43 and the pin pulling structure 44 can be synchronously displaced, thereby completing the above-mentioned pin insertion operation and needle pulling operation.

[0107] Specifically, the needle pulling structure 44 includes a push member 441. When the first plug-in member 41 brings the push member 441 close to the reel, the tail boss (such as Fig.11 As shown in the figure, the push member 441 can pass over the push member 441 and be located on the side of the push member 441 away from the reel. When the first plug-in member 41 is away from the reel, the push member 441 abuts against the tail boss of the half needle and pushes the first half needle at the unloading station to move and realize the needle pulling operation.

[0108] In some embodiments, the push member 441 is elastically connected to the first substrate via an elastic member so as to be elastically displaceable relative to the first substrate. The push member 441 has an unlocking inclined surface (wedge-shaped surface) and a limiting surface, such as Fig.10 and Fig.11 As shown, the unlocking slope faces the first half needle 11 at the blanking station, and gradually moves away from the first half needle 11 at the blanking station in the direction close to the reel 13, and the limit surface is located on the side of the push member 441 away from the first half needle 11. During operation, when the first plug-in member 41 approaches the reel 13, the push member 441 also approaches the reel 13, and the tail of the first half needle 11 at the blanking station contacts and slides on the unlocking slope. Since the push member 441 is elastically connected to the first base body, it is pushed by the first half needle 11 at the blanking station, and the push member 441 overcomes the elastic force and avoids until the tail of the first half needle 11 at the blanking station passes over the push member 441 (for example, the push member 441 is embedded in the To the annular groove at the tail of the first half needle 11), so that the tail boss of the first half needle 11 in the unloading station is located on the side of the limiting surface away from the reel 13, and then the pushing member 441 recovers its state under the action of the elastic force; when the first plug-in member 41 is away from the reel 13, the pushing member 441 moves away from the reel 13 along with the first base, and the limiting surface abuts against the tail boss of the first half needle 11 in the unloading station, thereby pulling the first half needle 11 in the unloading station to move, so as to complete the needle pulling operation.

[0109] In this way, by elastically connecting the push piece 441 with the first substrate and forming an elastic avoidance elastic slope on the push piece 441, a one-way limit connection is achieved for the first half needle 11 at the unloading station (i.e., it avoids and passes in the direction close to the reel 13, and is limit-connected in the direction away from the reel 13). The control is performed by a purely mechanical structure without the intervention of other power sources, which is beneficial to saving kinetic energy loss and simplifying the control structure.

[0110] Here, the elastic connection between the push piece 441 and the first base can also be set as a telescopic connection, that is, the push piece 441 is linearly telescopically displaced in the direction of approaching and moving away from the first base, or can be set as a rotational connection, that is, the push piece 441 is rotationally connected to the first base, and the unlocking slope can be rotated by rotating the push piece 441 relative to the first base to avoid the tail of the first half needle 11 at the unloading station. When the push piece 441 is elastically connected to the first base through the elastic piece, a second guide structure for guiding the push piece 441 can also be provided to ensure the accuracy of the moving direction of the push piece 441.

[0111] Specifically, the push member 441 is configured as a wedge-shaped block, the elastic member is configured as a spring, and the push member 441 is connected to the first base through a mounting seat.

[0112] The mounting seat may be provided with a mounting groove, and the push member 441 is slidably connected in the mounting groove, and can protrude and hide in the mounting groove. In this way, the displacement of the push member 441 can be guided and the push member 441 can be accommodated through the mounting groove. At the same time, the elastic member and the second guide structure are both arranged in the mounting groove, which can improve the stability and reliability of the needle extraction structure 44 and help to improve the service life. The second guide structure includes a plurality of second guide rods, one end of which is connected to the push member, and the other end is passed through the mounting seat and slidably cooperates with the mounting seat. Here, a second linear bearing is arranged between the second guide rod and the mounting seat to ensure the stability of the linear sliding.

[0113] In some other embodiments, the push member 441 is a telescopic member, which is movably connected to the first substrate so that the telescopic member can extend and retract from the first substrate. For example, the needle pulling structure 44 can be set as a cylinder such as a cylinder or a hydraulic cylinder, and the telescopic member is set as a piston rod on the cylinder, or the needle pulling structure 44 is set as a solenoid valve, and the telescopic member is set as a valve core. During use, when the first substrate drives the needle pulling structure 44 to approach the reel 13, the telescopic member retracts relative to the first substrate so that the tail of the first half needle 11 at the unloading station passes over the telescopic member. When the first substrate drives the needle pulling structure 44 away from the reel 13, the telescopic member extends relative to the first substrate so that the tail of the first half needle 11 at the unloading station is against the telescopic member, and then the first substrate pulls the tail of the first half needle 11 at the unloading station through the telescopic member to move, so as to complete the needle pulling operation. In this way, the telescopic member is controlled by external power, with high response and sensitive action.

[0114] The pin insertion structure 43 includes a push plate, which is arranged on the first substrate. Specifically, the push plate can be connected to the first substrate, or can be a part of the first substrate. For example, when the first substrate is set as a sliding plate, the push plate and the sliding plate are set as one body. The push plate and the axial projection of the tail of the first half needle 11 in the winding station at least partially overlap, so that when the first substrate drives the push plate to approach the reel 13, the push plate and the tail of the first half needle 11 in the winding station are abutted, and then the first sliding plate pushes the tail of the first half needle 11 in the winding station to move through the push plate to complete the pin insertion operation. In this way, by the push plate and the tail of the first half needle 11 in the winding station abutting each other, the first sliding plate can drive the first half needle 11 in the winding station to move in one direction without using a connecting structure, and the structure is simple, stable and reliable.

[0115] The second plug-in piece 42 can also perform needle pulling and needle insertion operations on the second half needle at the unloading station through the same structure or a different structure. When the second half needle is inserted and pulled out through the same plug-in structure, the structure can be stuck in the tail of the second half needle at the unloading station and drive the second half needle to move back and forth.

[0116] For example, the second plug-in member 42 includes a second plug-in structure 45 , which is located opposite to the second half needle 12 of the winding needle at the blanking station, so that the second half needle 12 at the blanking station can be operated through the second plug-in structure 45 . When the winding needle is switched from the winding station to the unloading station, the second half needle 12 of the winding needle at the unloading station is connected to the second plug-in structure 45 on the second substrate, and then, the second substrate moves away from the reel 13, and the second substrate performs a needle pulling operation on the second half needle 12 at the unloading station through the second plug-in structure 45, that is, the second substrate pulls the second half needle 12 at the unloading station to move through the second plug-in structure 45 until the needle pulling operation is completed. Since the first substrate has performed a needle pulling operation on the first half needle 11 at the unloading station, the unloading of the material roll can be completed after the second half needle 12 at the unloading station completes the needle pulling operation; then, the second substrate approaches the reel 13, and the second substrate performs a needle insertion operation on the second half needle 12 at the unloading station through the second plug-in structure 45, that is, the second substrate pushes the second half needle 12 at the unloading station to move through the second plug-in structure 45 until the needle insertion operation is completed.

[0117] Specifically, the second plug-in structure 45 includes a push-pull plate, such as Figure 10-11 As shown, the push-pull plate is arranged on the second substrate, and the push-pull plate can be connected to the second substrate, or can be a part of the second substrate. For example, when the second substrate is arranged as a sliding plate, the push-pull plate and the sliding plate are arranged as one body. Moreover, when the second half needle 12 is in the blanking station, the push-pull plate is located in the push-pull groove 101 (as shown in FIG. 1 ) at the tail of the half needle. Fig.11 The tail of the middle half needle is shown in the annular groove on one side of the tail boss, and the push-pull groove 101 is limited in the axial direction of the reel 13. In this way, through the design of the push-pull plate, the push-pull plate can be matched with the original push-pull groove 101 on the second half needle 12, with a simple structure, stable and reliable.

[0118] Specifically, the side of the push-pull plate facing the second half needle 12 is configured to be arc-shaped and matched with the bottom of the push-pull groove 101, so that the push-pull groove 101 and the push-pull plate have a larger contact area.

[0119] During actual use, when the second half needle 12 is in the unloading station, the tail of the second half needle 12 is opposite to the second plug-in structure 45, so that the push-pull plate is located in the push-pull groove 101, and in the axial direction of the reel 13, the push-pull plate forms a limit on the push-pull groove 101, so that the second substrate can perform needle insertion and needle extraction operations on the second half needle 12 in the unloading station through the second plug-in structure 45; correspondingly, when the second half needle 12 is in the winding station, the tail of the second half needle 12 is staggered with the second plug-in structure 45, so that the push-pull plate extends out of the push-pull groove 101, and then in the axial direction of the reel 13, the push-pull plate cancels the limit on the push-pull groove 101.

[0120] The present application also provides a winding device, including a winding head as described in any of the above embodiments. The winding needle drive mechanism and the needle insertion and extraction mechanism of the winding device are both simplified in structure, and the entire winding head has a simplified and compact structure, reasonable arrangement, and high stability.
