[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

If the specific posture changes, the directional indicators will also change accordingly.

[0041] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0042] This utility model discloses a winding and unwinding device, which is mainly used to realize the winding and unwinding operations of the roll material. During the winding process, the device tightly and neatly winds the roll material onto the winding shaft of the material roll; during the unwinding process, the device controls the release speed and tension of the roll material to ensure the smooth operation of the roll material.

[0043] In one embodiment, please refer to Figures 1 to 9 The winding and unwinding device 100 includes a support frame 110, a material shaft 120, a drive mechanism 130, and a correction mechanism 140. The material shaft 120 is rotatably mounted on the support frame 110 and is used to fix the material roll 10. The drive mechanism 130 is mounted on the support frame 110 and is connected to the material shaft 120 for transmission, so as to drive the material shaft 120 to rotate the material roll 10, thereby realizing the winding and unwinding of the material roll 10. The correction mechanism 140 is mounted on the support frame 110 and is connected to the material shaft 120 for transmission, so as to adjust the axial position of the material shaft 120 and the material roll 10 relative to the support frame 110, thereby realizing the correction and straightening of the material roll 10.

[0044] In this embodiment, the drive mechanism 130 includes a first drive motor 131 and a drive shaft 132 that is drivenly connected to the output shaft of the first drive motor 131. The material shaft 120 is slidably connected to the drive shaft 132 so that the end of the material shaft 120 can be circumferentially positioned and axially moved relative to the drive shaft 132. The material shaft 120 and the drive shaft 132 use their own structure to limit the correction movement trajectory of the material shaft 120, reducing the setting of the track mechanism and facilitating the miniaturization of the winding and unwinding device 100.

[0045] In one embodiment, please refer to Figure 9One of the drive shaft 132 and the material shaft 120 is provided with a receiving groove 133, and the other is provided with a plug 121. The groove wall of the receiving groove 133 and the plug 121 are provided with a key protrusion and the other is provided with a keyway. The plug 121 is inserted into the receiving groove 133 and can move axially relative to the support frame 110. The key protrusion abuts against the groove wall of the keyway in a circumferential manner so as to transmit the rotational motion of the drive shaft 132 to the material shaft 120 and the material roll 10. By setting the cooperation relationship between the drive shaft 132 and the material shaft 120 in this way, not only can the rotational motion of the first drive motor 131 be transmitted to the material shaft 120, thereby driving the material shaft 120 to rotate to perform the winding and unwinding action, but the material shaft 120 and the drive shaft 132 can also use their own structure to limit the correction movement trajectory of the material shaft 120.

[0046] Specifically, a receiving groove 133 is provided on the drive shaft 132, and a plug 121 is formed at the end of the material shaft 120. A key protrusion extending axially is formed on the groove wall of the receiving groove 133, and a keyway extending axially is provided on the outer peripheral wall of the plug 121. This allows the material shaft 120 to not only move axially relative to the drive shaft 132 for correction, but also to receive the rotational motion transmitted from the drive shaft 132 to drive the material shaft 120 and the material roll 10 to rotate.

[0047] In one embodiment, please refer to Figures 1 to 9 The drive mechanism 130 also includes a coupling 135, which drives the output shaft of the first drive motor 131 and the transmission shaft 132, thereby ensuring the stability and reliability of the first drive motor 131 transmitting rotational motion to the transmission shaft 132.

[0048] In one embodiment, please refer to Figures 1 to 9 The drive mechanism 130 also includes a mounting frame 136, which is fixed to the support frame 110. The drive shaft 132 and the material shaft 120 are both rotatably mounted on the mounting frame 136. The first drive motor 131 is fixed to the mounting frame 136, thereby realizing the installation and setting of each component. It can be understood that several bearings are provided in the winding and unwinding device 100 to support the stability and reliability of the rotation of rotatable components such as the drive shaft 132 and the material shaft 120.

[0049] In one embodiment, please refer to Figures 1 to 9The correction mechanism 140 includes a second drive motor 141, a first pulley 142, a transmission belt 143, a second pulley 144, a lead screw 145, a nut 146, and a connector 147. The lead screw 145 has a shaft hole 148 and is sleeved on the transmission shaft 132 so that the transmission shaft 132 can rotate relative to the lead screw 145. The nut 146 is sleeved on the outer wall of the lead screw 145 and threadedly connected to the lead screw 145. The connector 147 connects the nut 146 and the material shaft 120. The first pulley 142 is fixed to the output shaft of the second drive motor 141, the second pulley 144 is sleeved on the outer wall of the lead screw 145, and the transmission belt 143 is wound between the first pulley 142 and the second pulley 144.

[0050] With this configuration, the second drive motor 141 can transmit rotational motion to the first pulley 142, which in turn can transmit the rotational motion to the second pulley 144 via the transmission belt 143. The second pulley 144 can drive the lead screw 145 to rotate, thereby driving the nut 146 to move axially. The axial movement of the nut 146 can drive the connector 147, the material shaft 120, and the material roll 10 to move axially relative to the support frame 110, thereby achieving the correction and straightening of the material roll 10.

[0051] Specifically, the correction mechanism 140 also includes a fixing frame 149, and the second drive motor 141 is fixed to the mounting frame 136 through the fixing frame 149, thereby realizing the installation of the second drive motor 141.

[0052] In one embodiment, please refer to Figures 1 to 8 The winding and unwinding device 100 also includes a sensor 150 and an adjusting bracket 160. The sensor 150 is mounted on the support frame 110 via the adjusting bracket 160 and is used to sense the winding and unwinding of the material roll 10. A correction mechanism 140 is provided to monitor the position of the winding and unwinding of the material roll in real time. Once a positional deviation is detected, correction adjustment is immediately performed. This real-time capability not only ensures the continuity and stability of winding and unwinding but also reduces equipment downtime caused by material positional deviation, improving equipment utilization and production efficiency. Specifically, the sensor 150 is a photoelectric sensor.

[0053] In this embodiment, the adjusting bracket 160 includes a fixed rod 161, a sliding frame 162, an adjusting member 163, a locking member 164, and an adjusting rod 165. The fixed rod 161 is fixed to the support frame 110. The sliding frame 162 is sleeved on the fixed rod 161 and can move axially relative to the fixed rod 161. The adjusting member 163 passes through the sliding frame 162 and abuts against the fixed rod 161 to lock the axial position of the sliding frame 162 relative to the fixed rod 161. One end of the adjusting rod 165 is provided with an adjusting groove 166, and the other end is fixed with a sensor 150. The locking member 164 passes through any position of the adjusting groove 166 and is detachably connected to the sliding frame 162 to adjust the position of the sensor 150 relative to the support frame 110.

[0054] With this configuration, the position of the sensor 150 relative to the support frame 110 and the roll material can be flexibly adjusted, making it easier for the sensor 150 to sense the roll material being wound up and unwound on the roll material 10. Specifically, the winding and unwinding device 100 also includes a guide roller 170, which is rotatably mounted on the support frame 110 to facilitate control of the extension trajectory of the roll material.

[0055] In one embodiment, the take-up and unwinding device 100 further includes a hand-operated expansion shaft, which is sleeved on the material shaft 120 and used to fix and release the material roll.

[0056] This utility model embodiment also discloses a battery current collector production device. Please refer to [link / reference]. Figures 1 to 9 The battery current collector production equipment is mainly used to manufacture current collectors in batteries. The battery current collector production equipment includes the winding and unwinding device 100 of any of the above embodiments.

[0057] It is understood that in the winding and unwinding device 100 of the above embodiment, the drive mechanism 130 includes a first drive motor 131 and a transmission shaft 132 that is drivenly connected to the output shaft of the first drive motor 131. The material shaft 120 is slidably connected to the transmission shaft 132 so that the end of the material shaft 120 can be circumferentially positioned and axially moved relative to the transmission shaft 132. The material shaft 120 and the transmission shaft 132 use their own structure to limit the correction movement trajectory of the material shaft 120, reducing the setting of the track mechanism, which is conducive to the miniaturization of the winding and unwinding device 100, and thus facilitates the spatial arrangement of the winding and unwinding device 100 on the battery current collector production equipment.

[0058] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
