Description

Technical Field

[0001] The utility model relates to the technical field of coiling devices, in particular to a feeding and pulling-back device for cutting coiled materials of hydrogen fuel cells. Background Art

[0002] During the production process of battery coils, operators rely on battery coil handling equipment to transport the battery coils. However, existing handling equipment has efficiency problems during the loading process. They cannot quickly and effectively align with the material axis. This limitation leads to the cumbersomeness of the battery coil loading process and increases the operation time.

[0003] A Chinese patent (CN219708612U) discloses an automatic feeding and pulling back structure for battery coils. Its core working principle involves the use of a shell, one side of which is provided with an operation panel, and the other side is provided with a transport shaft. A through hole is provided at the end of the transport shaft, and a camera electrically connected to the operation panel is provided at the end of the through hole to capture the alignment of the transport shaft and the material shaft of the equipment in real time, thereby simplifying the alignment process and reducing the observation and movement of operators. An annular block is sleeved on the transport shaft, which is connected to the annular block by two electric push rods. An electromagnet is installed on the annular block, which cooperates magnetically with the winding core of the battery coil to achieve the fixation and release of the battery coil. In addition, a buffer block is provided at the end of the through hole to reduce the impact of vibration of the transport shaft on the camera during alignment, and rollers and reinforcing rods are provided to enhance the structural strength and support, thereby ensuring the stability and durability of the transport shaft during long-term use.

[0004] Although the use of cameras reduces the movement and observation of personnel, the final result still needs to be observed by the human eye, so errors are inevitable. Although the loss of battery rolls is minimized by rollers, there is still a certain amount of loss. Utility Model Content

[0005] In view of the above problems, a feeding and pulling back device for cutting hydrogen fuel cell coils is provided, comprising a pushing plate for transporting battery coils, a rotating shaft which is sleeved with the pushing plate and drives the pushing plate, a movable track which ensures the movement of the pushing plate along the axis and is arranged on both sides of the device, a transfer roller for transporting battery coils, a positioning mechanism for confirming that the rotating shaft is coaxial with the transfer roller, and an operating panel for controlling the rotation of the rotating shaft, wherein a support frame is provided on the movable track, and the positioning mechanism comprises a vertical signal transmitter which is arranged on the support frame; a horizontal signal transmitter which is arranged on the moving track; and a signal receiver which is arranged on the transfer roller.

[0006] Preferably, the outer surface of the rotating shaft is provided with threads, and the pushing plate is connected to the rotating shaft via the threads.

[0007] Preferably, limit blocks are provided on both sides of the push plate, and sliding grooves adapted to the limit blocks are provided in the movable tracks on both sides of the device.

[0008] Preferably, an electromagnetic sheet is provided on the pushing disk, and the electromagnetic sheet is electrically connected to the device.

[0009] Preferably, the contact surface between the pushing disk and the battery coil is provided with a plurality of supporting bases.

[0010] Preferably, a cavity is provided inside the transfer roller, the inner diameter of the cavity is larger than the outer diameter of the contact surface with the push disk, and the overall outer diameter of the transfer roller is smaller than the size of the supporting base.

[0011] Preferably, an abutment plate is provided on the movable track and the support frame, and a through hole is provided on the abutment plate. The through hole is used for the passage of a connecting rod. After the connecting rod passes through the abutment plate, a cleaning brush is connected. The cleaning brush is used to clean the horizontal signal transmitter and the vertical signal transmitter. A spring is provided between the cleaning brush and the abutment plate along the axial direction of the connecting rod, and the spring is fixedly connected to the cleaning brush and the abutment plate respectively.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model has made significant innovations in the design of the feeding and pulling back device by introducing a set of precise positioning mechanisms, which are composed of vertical and horizontal signal transmitters and signal receivers installed on the transfer rollers. This advanced electronic positioning system can automatically detect and judge the coaxiality between the transfer roller and the rotating shaft, thereby ensuring the accuracy of the feeding and pulling back actions of the hydrogen fuel cell coils during the cutting process. Compared with the traditional method of relying on human eyes for judgment, this automated positioning mechanism effectively eliminates the errors that may be caused by human factors and significantly improves the accuracy of the entire positioning process. In addition, the introduction of automated operation not only improves work efficiency, but also reduces the time and labor intensity of manual operation, making the entire feeding and pulling back process more efficient and accurate. This innovative positioning mechanism design provides a more reliable and efficient solution for the cutting of hydrogen fuel cell coils, which helps to improve the quality and production efficiency of the final product.

[0014] 2. The utility model adopts an innovative threaded connection method in design, which closely combines the rotating shaft and the pushing disk. The cleverness of this connection method is that it can ensure that when the rotating shaft rotates, the pushing disk can move stably in the radial direction without any rotation phenomenon. This is very important for maintaining the stability of the battery coil during the feeding process, because it can avoid the coil deviation or instability that may be caused by the rotation of the pushing disk. In addition, in order to further improve the stability of the system, the utility model also specially designs a matching mechanism of the limit block and the slide groove. Through this matching, the movement trajectory of the pushing disk is accurately limited, thereby further enhancing the stability of the entire feeding system. This sophisticated design not only improves the accuracy of the feeding process, but also ensures the long-term stable operation of the system, which helps to improve production efficiency and product quality.

[0015] 3. A notable feature of the utility model is the specially designed electromagnetic sheets on its push disk. These electromagnetic sheets have strong adsorption capacity and can firmly adsorb the battery coils to ensure that the coils will not fall off during the movement, thereby avoiding possible damage to the coils. In addition, the design of the support base has also been carefully considered. It not only provides stable support for the battery coils, but also effectively reduces the relative rotation between the battery coils and the transfer rollers during the transportation process through its inclined surface design and retractable mechanism. This design is of great significance for protecting the high-value hydrogen fuel cell coils, because it minimizes the damage to the coils during the production and processing process, thereby ensuring the integrity of the materials and the final quality of the products. Through these ingenious designs, the utility model not only improves the stability and reliability of the feeding process, but also provides an effective solution for protecting expensive materials, which has a positive impact on improving production efficiency and reducing production costs.

DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-Figure 9: A feeding and pulling back device for cutting hydrogen fuel cell coils, including a pushing plate 4 for transporting battery coils, a rotating shaft 3 that is sleeved with the pushing plate 4 and drives the pushing plate 4, a moving track 5 that ensures the movement of the pushing plate 4 along the axis, a transfer roller 6 for transferring battery coils, a positioning mechanism 2 for confirming that the rotating shaft 3 is coaxial with the transfer roller 6, and an operating panel 1 for controlling the rotation of the rotating shaft 3, the moving track 5 is arranged on both sides of the device, and a support frame 21 is provided at the moving track 5 away from the operating panel 1, the support frame 21 is fixedly connected to the moving track, the positioning mechanism 2 includes a vertical signal transmitter 211, a horizontal signal transmitter 22 and a signal receiver 23, the vertical signal transmitter 211 is arranged on the support frame 21; the horizontal signal transmitter 22 is arranged on the moving track 5; and a plurality of signal receivers 23 are arranged along the circumference of the transfer roller 6.

[0031] At present, whether the transfer roller 6 and the transport axis are coaxial mainly depends on the assistance of the human eye, and some errors are inevitable. In the utility model, in order to avoid the error of the human eye, a positioning mechanism 2 is adopted. Specifically, a plurality of signal receivers 23 are arranged along the circumference of the transfer roller 6, and a horizontal signal transmitter 22 and a vertical signal transmitter 211 are respectively arranged on the conveying end of the movable track 5 and the support frame 21. When the signal receiver 23 on the transfer roller 6 simultaneously receives the signal emitted by the vertical signal transmitter 211, that is, when the rotating shaft 3 and the transfer roller 6 are coaxial, the operation panel 1 will feedback a signal, and the feedback signal can be a conversion of a signal light, displaying a red light when not coaxial, and turning to a green light when coaxial. When the green light is displayed, the operator controls the rotation of the rotating shaft 3 through the operation panel 1, and the rotating shaft 3 drives the push plate 4 to move along the radial direction of the axis, and the push plate 4 drives the battery coil to move until the battery coil is transported to the transfer roller 6. The above-mentioned signal and the vertical signal transmitter 211 The signal emitted can be an infrared signal, but is not limited to this.

[0032] Reference Figure 1-Figure 9 : The outer surface of the rotating shaft 3 is provided with threads, and the pushing plate 4 is connected to the rotating shaft 3 through the threads.

[0033] When the rotating shaft 3 rotates, the pushing plate 4 connected to the rotating shaft 3 by a thread will move precisely along the radial direction of the rotating shaft 3. This movement mechanism of the pushing plate 4 is essentially consistent with the principle of interaction between the bolt and the nut through the thread. In the matching mechanism of the bolt and the nut, the rotation of the bolt causes the nut to move linearly along the axis of the bolt without causing rotation around the axis. Similarly, in the mechanism of the present invention, the movement of the pushing plate 4 is also based on this mechanical principle, ensuring that it can achieve precise radial displacement when the rotating shaft 3 rotates, eliminating any unexpected rotational movement.

[0034] Reference Figure 4-Figure 6 : Limit blocks 41 are arranged on both sides of the push plate 4, and sliding grooves 51 adapted to the limit blocks 41 are opened in the moving tracks 5 on both sides of the device.

[0035] In order to prevent the pushing plate 4 from rotating unexpectedly with the rotating shaft 3, a limiting structure is provided in the device provided by the utility model, and outwardly extending limiting blocks 41 are arranged on both sides of the pushing plate 4. Correspondingly, slide grooves 51 matching the limiting blocks 41 are provided in the moving tracks 5 on both sides of the equipment. This design ensures that the pushing plate 4 only moves linearly along the radial direction of the rotating shaft 3, and does not rotate with the rotating shaft 3. This structure enhances the stability of the movement of the pushing plate 4, and ensures precise control of the pushing plate 4 during the feeding of the battery coil and the pulling back of the pushing plate 4 after the feeding is completed, effectively preventing the damage of the battery coil caused by the unexpected rotation of the pushing plate 4.

[0036] Reference Figure 4 and Figure 5 : An electromagnetic sheet 42 is provided on the driving disk 4, and the electromagnetic sheet 42 is electrically connected to the device through 41 in the moving track 5.

[0037] The design of the electromagnetic sheet 42 plays a key role in the present invention. It ensures that the battery coil is firmly fixed to the push plate 4 through a strong magnetic force, effectively preventing the battery coil from falling off during the movement of the push plate 4. This fixing method not only enhances the stability of the battery coil during feeding and pulling back operations, but also reduces the risk of the battery falling off due to inertia when the transportation process is suddenly stopped due to production interruption or equipment failure. This feature of the electromagnetic sheet 42 provides a guarantee for the accurate feeding and safe pulling back of the battery coil, while improving the efficiency and reliability of the entire production process.

[0038] Reference Figure 5 : The push plate 4 and the battery coil sleeve surface are provided with a plurality of support bases 43.

[0039] The support base 43 is used to support the battery coil.

[0040] Reference Figure 1-Figure 9 A cavity 61 is provided inside the transfer roller 6 , the inner diameter of the cavity 61 is larger than the outer diameter of the sleeve surface with the push disk 4 , and the overall outer diameter of the transfer roller 6 is smaller than the size of the support base 43 .

[0041] When the pushing plate 4 drives the battery coil to be transported to the transfer roller 6, the pushing plate 4 moves along the rotating shaft 3 until the pushing plate 4 enters the cavity 61 inside the transfer roller 6 and contacts the transfer roller 6. The contact surface between the support base 43 and the transfer roller 6 is inclined. During the continued transportation, the support base 43 is pressed to shrink inside the pushing plate 4, and the battery coil is gradually sent to the transfer roller 6 until the transportation is completed. Under ideal circumstances, until the transportation is completed, the battery coil will not rotate relative to the transfer roller 6, thereby minimizing the damage to the battery coil. When the transportation is completed, the electrical connection between the electromagnetic sheet 42 and the device is disconnected through the operation panel 1, the electromagnetic sheet 42 no longer absorbs the battery coil, and the rotating shaft is reversed to drive the pushing plate to pull back. The above-mentioned contraction mechanism can be a groove provided on the surface of the pushing plate 4, and a reset mechanism is provided in the groove, and the reset mechanism is connected to the support base 43.

[0042] Reference Figure 10-12 : An abutment plate 7 is provided on the movable track 5 and the support frame. A through hole is provided on the abutment plate 7. The through hole is used for the passage of a connecting rod 71. After the connecting rod 71 passes through the abutment plate 7, a cleaning brush 72 is connected. The cleaning brush 72 is used to clean the horizontal signal transmitter 22 and the vertical signal transmitter 211. A spring is provided between the cleaning brush 72 and the abutment plate 7 along the axial direction of the connecting rod 71. The spring is fixedly connected to the cleaning brush 72 and the abutment plate 7 respectively.

[0043] When the spring is in the initial state, due to the existence of its own tension, the cleaning brush 72 is away from the horizontal signal transmitter 22 and the vertical signal transmitter 211, so as to facilitate the coaxial positioning of the rotating shaft 3 and the transfer roller 6. When the positioning is completed, the pushing plate 4 is close to the transfer roller 6. During this process, the pushing plate 4 will first touch the connecting rod 71. At this time, the spring will be stretched, and the cleaning brush 72 begins to approach the horizontal signal transmitter 22 and the vertical signal transmitter 211 until it is completely swept. Similarly, when the transfer is completed, the pushing plate 4 is pulled back, the spring loses its thrust and begins to reset. The spring reset drives the cleaning brush 72 to sweep the horizontal signal transmitter 22 and the vertical signal transmitter 211 again to achieve the cleaning effect.

[0044] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
