[0026] The second rotating shaft penetrates the second bearing pair, and the second cylinder of the clutch mechanism is sleeved outside the second bearing pair;

[0027] The transmission pulley assembly comprises a driving pulley, a transmission belt, and a driven pulley, and the transmission belt is sleeved on the driving pulley and the driven pulley;

[0028] The motor;

[0029] The machine base is mounted on the machine base connector;

[0030] The driving gear of the gear pair is embedded in the buried hole one of the machine base, and the driven gear is embedded in the buried hole two of the machine base;

[0031] The gear ring assembly is sleeved in the through hole one of the machine base, and the concave roller shaft assembly is matched with the convex track on the surface of the through hole one, and the gear ring assembly rotates around the central shaft under the driving of the motor;

[0032] The unwinding device and the winding device are both mounted on the gear ring assembly through the support;

[0033] The bearing inner ring of the third bearing pair is fixed on the rotating shaft one, and the driving pulley of the transmission pulley assembly is sleeved on the bearing of the third bearing pair and is fixed with the bearing outer ring; The driving pulley of the transmission pulley assembly is located below the damping friction disc of the unwinding device, and the transmission between the two is through surface friction;

[0034] The driven pulley of the transmission pulley assembly is sleeved on the second rotating shaft, which is located below the clutch mechanism and is fixed with the first half-cylinder of the clutch mechanism;

[0035] The motor is installed on the base, and the motor shaft penetrates into the embedded hole and is connected with the driving gear.

[0036] The automatic winding manipulator for the fireproof insulating tape of the copper bar connector of the new energy battery pack comprises a unwinding device, a winding device and a transmission pulley assembly, which are all installed on the gear ring assembly and rotate with the gear ring assembly under the driving of the motor.

[0037] The damping friction disc of the unwinding device and the driving wheel of the transmission pulley assembly are connected through surface friction transmission, and the spring pressure value of the helical spring one applied to the damping friction disc is adjusted by screwing the adjusting bolt to compress the helical spring one, so as to adjust the surface friction force F between the damping friction disc and the driving wheel. 摩 The size.

[0038] The half cylinder one of the clutch mechanism in the winding device is fixed with the driven wheel of the transmission pulley assembly, and the outer diameter of the cylinder three composed of the half cylinder one and the half cylinder two increases synchronously in the winding direction of the winding device, so as to switch the clutch state of the clutch mechanism.

[0039] Therefore, when the automatic winding manipulator is combined with the automatic winding equipment for the fireproof insulating tape of the copper bar connector of the new energy battery pack, the matched accessories include a fireproof insulating tape assembly (including a winding core one and a fireproof insulating tape wound on the surface of the winding core one) and a winding core two, wherein the winding core one of the fireproof insulating tape assembly is sleeved outside the sleeve of the unwinding device and locked by the eccentric part of the eccentric shaft sleeve protruding out of the sleeve, and the winding core two is sleeved outside the cylinder three of the winding device. Then, the head of the outermost fireproof insulating tape of the fireproof insulating tape assembly (in the state that the release paper is peeled off) needs to be manually pre-wound and bonded on the surface of the copper bar connector to be processed. During the self-rotation of the gear ring assembly driven by the motor, the fireproof insulating tape will exert a pulling force F 拉 in the tangential direction of the sleeve. 拉 > the above F 摩 , the fireproof insulating tape will always be in a tension state and continuously automatically wound on the copper bar connector. At the same time, the sleeve, the damping friction disc and the driving wheel of the transmission pulley assembly rotate synchronously. Due to the linkage of the transmission belt in the transmission pulley assembly, the driven wheel of the transmission pulley assembly, the cylinder two of the clutch mechanism in the winding device and the half cylinder one also rotate synchronously. The self-rotation direction is the winding direction of the winding device. The outer diameter of the cylinder three composed of the half cylinder one and the half cylinder two increases synchronously, and the clutch mechanism switches the state to lock and drive the winding core two to rotate. At this time, only the end of the release paper peeled off from the head of the fireproof insulating tape needs to be manually pre-wound on the winding core two, so that the automatic winding manipulator can synchronously wind the release paper peeled off from the fireproof insulating tape installed on the unwinding device.

[0040] In addition, the transmission belt wheel assembly is used to realize linkage between the unwinding self-rotation of the unwinding device and the winding self-rotation of the winding device in the structure of the automatic winding manipulator, because the outer diameter of the fireproof insulating tape assembly on the unwinding device gradually linearly decreases in the automatic winding process of the copper bar connector by the automatic winding manipulator, and the outer diameter of the release paper wound on the winding device linearly increases, and the diameters of the driving wheel and the driven wheel of the transmission belt wheel assembly are both fixed values, and the transmission belt in the transmission belt wheel assembly allows transmission slip to occur between the driving wheel and the driven wheel.

[0041] Further, the automatic winding manipulator for the fireproof insulating tape of the copper bar connector of the new energy battery pack further comprises a tape cutting device.

[0042] When the automatic winding manipulator is used in the automatic winding equipment for the fireproof insulating tape of the copper bar connector of the new energy battery pack, the automatic winding manipulator can be arbitrarily translated or rotated in the multi-axis (generally four or five axes) direction of the equipment to adjust the real-time posture of the automatic winding manipulator, so as to realize automatic cutting of the fireproof insulating tape by the tape cutting device in the structure of the automatic winding manipulator, that is, to improve the automation degree of the automatic winding manipulator. At the same time, if the head of the fireproof insulating tape is manually fixed on the tape cutting device in advance, the head of the fireproof insulating tape can be automatically initially adhered on the copper bar connector to be processed by adjusting the real-time posture of the automatic winding manipulator, further improving the automation degree of the automatic winding manipulator.

[0043] Further, the automatic winding manipulator for the fireproof insulating tape of the copper bar connector of the new energy battery pack further comprises:

[0044] The first tensioning roller for tensioning the release paper between the unwinding device and the winding device, and the second tensioning roller for tensioning the tape between the unwinding device and the tape cutting device are both installed on the gear ring assembly.

[0045] The first tensioning roller can further ensure that the release paper is always tensioned between the unwinding device and the winding device, and the second tensioning roller can also further ensure that the tape is always tensioned between the unwinding device and the tape cutting device.

[0046] Compared with the prior art, the automatic winding manipulator for the fireproof insulating tape of the copper bar connector of the new energy battery pack has the following technical advantages:

[0047] 1. The automatic winding manipulator for the fireproof insulating tape of the copper bar connector of a new energy battery pack, when combined with the automatic winding equipment for the fireproof insulating tape of the copper bar connector of a new energy battery pack, can synchronously wind the release paper peeled off from the fireproof insulating tape installed on the unwinding device.

[0048] 2.

[0097] Therefore, when the automatic winding mechanical hand of the application is used in the automatic winding equipment of the fireproof insulating tape for the copper bar connector of the new energy battery pack, the matched accessories include the fireproof insulating tape assembly 8 (including the winding core one 8-1 and the fireproof insulating tape 8-2 which is wound on the surface of the winding core one 8-1 layer by layer) and the winding core two 9, wherein the winding core one 8-1 of the fireproof insulating tape assembly 8 is sleeved outside the sleeve 5-7 of the unwinding device 5, and is locked with the sleeve 5-7 through the eccentric shaft sleeve 5-8 which protrudes from the eccentric part 5-8-2 of the sleeve 5-7, and the winding core two 9 is sleeved outside the cylinder three of the winding device 6. Then, the tape head of the outermost fireproof insulating tape 8-2 of the fireproof insulating tape assembly 8 (in the state that the release paper 16 is peeled off) needs to be pre-wound and bonded on the surface of the copper bar connector to be processed by manual operation. During the self-rotation process of the motor 10 driven gear ring assembly 4, the fireproof insulating tape 8-2 will exert a pulling force F in the tangential direction of the sleeve 5-7 拉 , at this time, as long as F 拉 > the above F 摩 , the fireproof insulating tape 8-2 will always maintain a tension state and continuously automatically wind the copper bar connector, and the sleeve 5-7, the damping friction disc 5-6 and the driving wheel 7-1 of the transmission belt wheel assembly 7 rotate synchronously. Due to the linkage of the transmission belt 7-2 in the transmission belt wheel assembly 7, the driven wheel 7-3 of the transmission belt wheel assembly 7 and the cylinder two 6-3-1 and the half cylinder one 6-3-2 of the clutch mechanism 6-3 in the winding device 6 also rotate synchronously, and the self-rotation direction is the winding direction of the winding device 6. The outer diameter of the cylinder three which is composed of the half cylinder one 6-3-2 and the half cylinder two 6-3-3 together increases synchronously, the clutch mechanism 6-3 switches state to lock and drive the winding core two 9 to rotate. At this time, only the end of the release paper 16 which is peeled off from the tape head of the fireproof insulating tape 8-2 needs to be pre-wound on the winding core two 9 by manual operation, so that the automatic winding mechanical hand of the application can synchronously wind the release paper 16 which is peeled off from the fireproof insulating tape 8-2 installed on the unwinding device 5.

[0098] In addition, the automatic winding mechanical hand of the present application adopts the transmission belt wheel assembly 7 to realize linkage between the unwinding self-rotation of the unwinding device 5 and the winding self-rotation of the winding device 6, because the outer diameter of the fireproof insulating tape assembly 8 on the unwinding device 5 gradually linearly decreases in the automatic winding process of the copper bar connector by the automatic winding mechanical hand, while the outer diameter of the release paper 16 wound on the winding device 6 linearly increases. Considering that the diameters of the driving wheel 7-1 and the driven wheel 7-3 of the transmission belt wheel assembly 7 are both fixed values, the transmission belt 7-2 in the transmission belt wheel assembly 7 allows the transmission slip to occur between the driving wheel 7-1 and the driven wheel 7-3. In the embodiment, the diameter of the driving wheel 7-1 of the transmission belt wheel assembly 7 is the same as the outer diameter of the fireproof insulating tape 8-2 wound on the fireproof insulating tape assembly 8, and the diameter of the driven wheel 7-3 is the same as the outer diameter of the core shaft part of the winding core two 9. Therefore, at the beginning of the automatic winding of the copper bar connector by the automatic winding mechanical hand, the driving wheel 7-1 of the transmission belt wheel assembly 7 rotates one circle, and according to the diameter ratio of the driving wheel 7-1 and the driven wheel 7-3, the corresponding rotation speed of the driven wheel 7-3 is converted into the transmission ratio. Because the diameter ratio of the driving wheel 7-1 and the driven wheel 7-3 in the embodiment is 3:1, the driven wheel 7-3 needs to rotate three circles and does not have obvious slip. However, as the automatic winding process goes to the later stage, the outer diameter of the release paper 16 wound on the unwinding device 5 starts to increase, and the driven wheel 7-3 and the transmission belt 7-2 will have obvious slip. However, the above slip phenomenon does not affect the synchronous tension winding of the release paper 16 separated from the fireproof insulating tape 8-2 installed on the unwinding device 5 by the automatic winding mechanical hand.

[0099] As a second embodiment of the present application, the automatic fireproof insulating tape winding mechanical hand for the copper bar connector of the new energy battery pack provided in the embodiment has the same general structure as the first embodiment, as shown in Figure 11 However, the embodiment further includes a tape cutting device 13; the tape cutting device 13 is installed on the gear ring assembly 4.

[0100] When the automatic winding mechanical hand provided in the embodiment is used on the automatic fireproof insulating tape winding equipment combined with the copper bar connector of the new energy battery pack, the automatic winding mechanical hand can be arbitrarily translated or rotated in the multi-axis (generally four or five axes) direction of the equipment to adjust the real-time posture of the automatic winding mechanical hand, so as to realize the automatic cutting of the fireproof insulating tape 8-2 by the tape cutting device 13 in the structure of the automatic winding mechanical hand, that is, to improve the automation degree of the automatic winding mechanical hand. At the same time, if the head of the fireproof insulating tape 8-2 is manually fixed on the above-mentioned tape cutting device 13 in advance, the automatic initial adhesion of the head of the fireproof insulating tape 8-2 on the copper bar connector to be processed can also be realized by adjusting the real-time posture of the automatic winding mechanical hand, further improving the automation degree of the automatic winding mechanical hand.

[0101] As the third embodiment of the present application, the automatic wrapping manipulator of the fireproof insulating tape for the copper bar connector of the new energy battery pack provided in the embodiment has the same general structure as the second embodiment, as shown in Figure 12 However, the embodiment further comprises:

[0102] A tensioning roller one 14 for tensioning the release paper 16 between the unwinding device 5 and the winding device 6, and a tensioning roller two 15 for tensioning the tape between the unwinding device 5 and the tape cutting device 13, both of which are installed on the gear ring assembly 4.

[0103] The tensioning roller one 14 in the embodiment can further ensure that the release paper 16 is always kept tensioned between the unwinding device 5 and the winding device 6, and the tensioning roller two 15 can also further ensure that the tape is always kept tensioned between the unwinding device 5 and the tape cutting device 13.

[0104] The present application is not limited to the above-mentioned best embodiment, and anyone can derive other various forms of products under the inspiration of the present application, but regardless of any changes in shape or structure, any technical solution with the same or similar technical solution as the present application falls within the protection scope of the present application.
