Detailed Implementation

[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figure 1 and Figure 2 As shown, the battery flipping device 100 provided in this embodiment of the present invention includes a linear drive mechanism 1, a flipping drive mechanism 2, and a clamping mechanism 3. The flipping drive mechanism 2 is driven by the linear drive mechanism 1, and the linear drive mechanism 1 drives the flipping drive mechanism 2 to move along a first direction Z. The clamping mechanism 3 is driven by the flipping drive mechanism 2, and the flipping drive mechanism 2 drives the clamping mechanism 3 to rotate around a flipping axis, which is parallel to a second direction X. The clamping mechanism 3 clamps the battery 200 along the second direction X. The first direction Z is perpendicular to the second direction X.

[0022] For example, in Figure 1In the embodiment shown, the first direction Z is the height direction of the battery flipping device 100, the second direction X is the length direction of the battery flipping device 100 (that is, the length direction of the battery 200), and the third direction Y is the width direction of the battery flipping device 100. The first direction Z, the second direction X, and the third direction Y are perpendicular to each other.

[0023] The battery flipping device 100 provided in this embodiment of the present invention, when flipping a battery 200, first clamps the battery 200 along the second direction X using a clamping mechanism 3, and then drives the clamping mechanism 3 to rotate around a flipping axis parallel to the second direction X using a flipping drive mechanism 2, thereby achieving the flipping of the battery 200 clamped in the clamping mechanism 3. During this flipping process, the flipping drive mechanism 2 can be moved along the first direction Z by a linear drive mechanism 1 to adjust the positions of the flipping drive mechanism 2 and the clamping mechanism 3 in the first direction Z. This battery flipping device 100 achieves the flipping of the battery 200 by clamping first and then flipping, which is fast and precise and can reduce the vibration and impact on the battery 200.

[0024] In one embodiment, the battery flipping device 100 can be applied to the loading and unloading of the battery 200. During loading, the clamping mechanism 3 first clamps the battery 200 along the second direction X, and then the linear drive mechanism 1 drives the flipping drive mechanism 2 to move along the first direction Z. Once the flipping drive mechanism 2 reaches the loading position, the clamping mechanism 3 is rotated by the flipping drive mechanism 2, adjusting the battery 200 to a loading posture (e.g., an upright posture with the top surface facing up), thus achieving loading. During unloading, the clamping mechanism 3 first clamps the battery 200 along the second direction X, and then the flipping drive mechanism 2 drives the clamping mechanism 3 to rotate, adjusting the battery 200 to an unloading posture (e.g., a flat posture with the large surface facing up). Afterwards, the linear drive mechanism 1 drives the flipping drive mechanism 2 to move along the first direction Z until the flipping drive mechanism 2 reaches the unloading position, thus achieving unloading.

[0025] In one embodiment, when the flipping drive mechanism 2 drives the clamping mechanism 3 to flip, it can reciprocate between a first position and a second position. In the first position (e.g., Figure 1 As shown), the third direction Y is parallel to the width direction of the battery 200 clamped on the clamping mechanism 3. In the second position, the third direction Y is perpendicular to the width direction of the battery 200 clamped on the clamping mechanism 3.

[0026] In one embodiment, such as Figure 1 and Figure 2As shown, the linear drive mechanism 1 includes a first mounting bracket 11, a second mounting bracket 12, and a linear drive assembly 13. The second mounting bracket 12 is slidably connected to the first mounting bracket 11 along a first direction Z. The linear drive assembly 13 is mounted on the first mounting bracket 11 and is drively connected to the second mounting bracket 12. The linear drive assembly 13 is used to drive the second mounting bracket 12 to slide along the first direction Z. The flipping drive mechanism 2 is mounted on the second mounting bracket 12.

[0027] For example, in order to make the movement of the second mounting bracket 12 more stable, a slide rail structure 14 can be provided. The slide rail structure 14 is installed between the second mounting bracket 12 and the first mounting bracket 11, and the slide rail structure 14 realizes the sliding guidance of the second mounting bracket 12.

[0028] By mounting the linear drive assembly 13 on the first mounting bracket 11 and connecting the linear drive assembly 13 with the second mounting bracket 12, the second mounting bracket 12 can be driven to slide along the first direction Z by the linear drive assembly 13, thereby driving the flipping drive mechanism 2 mounted on the second mounting bracket 12 to move in the first direction Z and adjusting the position of the clamping mechanism 3 in the first direction Z.

[0029] In one embodiment, such as Figure 1 and Figure 2 As shown, the linear drive assembly 13 includes a driver 131, a lead screw 132, and a nut 133. The driver 131 is mounted on a first mounting bracket 11, and the output end of the driver 131 is connected to the lead screw 132. The axial direction of the lead screw 132 is parallel to the first direction Z, and the driver 131 is used to drive the lead screw 132 to rotate. The nut 133 is threadedly connected to the lead screw 132, and the second mounting bracket 12 is connected to the nut 133.

[0030] For example, the output of the driver 131 can be connected to the lead screw 132 via a coupling.

[0031] The driver 131 can be a drive motor.

[0032] By driving the lead screw 132 to rotate via the driver 131, the nut 133 threaded to the lead screw 132 can be moved in the first direction Z, which in turn can drive the second mounting bracket 12 to move in the first direction Z.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the flipping drive mechanism 2 includes a flipping drive assembly 21 and a flipping shaft 22. The flipping drive assembly 21 is mounted on the second mounting bracket 12, and the flipping shaft 22 is rotatably connected to the second mounting bracket 12 around the flipping axis. The flipping drive assembly 21 is connected to the flipping shaft 22 in a transmission manner, and the flipping drive assembly 21 is used to drive the flipping shaft 22 to rotate around the flipping axis.

[0034] The clamping mechanism 3 is mounted on the outer circumferential surface of the flipping shaft 22.

[0035] The rotation of the flip shaft 22 is driven by the flip drive assembly 21, thereby causing the clamping mechanism 3 mounted on the flip shaft 22 to flip.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, the flip drive assembly 21 includes a flip driver 211, a drive wheel 212, a driven wheel 213, and a transmission belt 214. The flip driver 211 is mounted on the second mounting bracket 12. The output end of the flip driver 211 is connected to the drive wheel 212. The flip driver 211 is used to drive the drive wheel 212 to rotate. The driven wheel 213 is connected to one end of the flip shaft 22. The transmission belt 214 is wound around the drive wheel 212 and the driven wheel 213.

[0037] For example, the flip driver 211 is a motor.

[0038] The drive wheel 212 is driven by the flip drive 211 to move the transmission belt 214 and make the driven wheel 213 rotate, thereby driving the flip shaft 22 connected to the driven wheel 213 to rotate, and then driving the clamping mechanism 3 to flip through the flip shaft 22.

[0039] In one embodiment, such as Figure 1 and Figure 2 As shown, a mounting block 23 can be provided on the outer peripheral surface of the flip shaft 22, and the clamping mechanism 3 is mounted on the mounting block 23 so that the clamping mechanism 3 can be installed on the flip shaft 22 through the mounting block 23.

[0040] In one embodiment, such as Figure 1 and Figure 2 As shown, the clamping mechanism 3 includes a clamping drive assembly 31, a first clamping plate 32, and a second clamping plate 33. The clamping drive assembly 31 is mounted on the outer peripheral surface of the flipping shaft 22. The clamping drive assembly 31 is connected to the first clamping plate 32 and the second clamping plate 33 in a transmission connection. The first clamping plate 32 and the second clamping plate 33 are arranged opposite to each other along the second direction X. The clamping drive assembly 31 is used to drive the first clamping plate 32 and the second clamping plate 33 to move closer to or further away from each other along the second direction X.

[0041] The first clamping plate 32 is used to cooperate with the second clamping plate 33 to clamp the battery 200.

[0042] When the clamping drive assembly 31 drives the first clamping plate 32 and the second clamping plate 33 to move closer to each other along the second direction X, the first clamping plate 32 and the second clamping plate 33 can clamp the battery 200.

[0043] In one embodiment, such as Figure 1 and Figure 2As shown, the clamping drive assembly 31 includes a clamping driver 311, a first drive plate 312, and a second drive plate 313. The clamping driver 311 is mounted on the outer peripheral surface of the flip shaft 22. The clamping driver 311 has a first output end and a second output end. The first output end is connected to the first drive plate 312, and the second output end is connected to the second drive plate 313. The clamping driver 311 is used to drive the first drive plate 312 and the second drive plate 313 to move closer to or further away from each other along the second direction X.

[0044] The first clamping plate 32 is mounted on the first drive plate 312, and the second clamping plate 33 is mounted on the second drive plate 313.

[0045] For example, the clamping driver 311 is a clamping cylinder.

[0046] By causing the clamping driver 311 to drive the first drive plate 312 and the second drive plate 313 to move closer or further away from each other along the second direction X, the first clamping plate 32 and the second clamping plate 33 are moved closer or further away from each other, thereby achieving the clamping of the battery 200.

[0047] In one embodiment, such as Figure 1 and Figure 2 As shown, the clamping mechanism 3 also includes a clamping mounting bracket 34 and a crash plate 35. The clamping mounting bracket 34 is mounted on the outer peripheral surface of the flip shaft 22, and the clamping drive assembly 31 is mounted on the clamping mounting bracket 34. The crash plate 35 is mounted on the clamping mounting bracket 34, and the clamping drive assembly 31 is located between the crash plate 35 and the flip shaft 22.

[0048] For example, with Figure 1 Taking the illustrated embodiment as an example, the first direction Z is the height direction of the battery flipping device 100. When the battery 200 is in an upright posture with its top surface facing up, the width direction of the battery 200 will be parallel to the width direction of the battery flipping device 100, that is, the width direction of the battery 200 will be parallel to the third direction Y. When the battery 200 is flipped to a flat posture with its large surface facing up, the width direction of the battery 200 will be parallel to the height direction of the battery flipping device 100, that is, the width direction of the battery 200 will be parallel to the first direction Z.

[0049] For example, the anti-collision plate 35 is mounted on the clamping mounting bracket 34 via the anti-collision mounting post 36.

[0050] By positioning the clamping drive assembly 31 between the anti-collision plate 35 and the flipping shaft 22, the battery 200 can only contact the anti-collision plate 35 when the clamping mechanism 3 clamps the battery 200, and will not collide with the clamping drive assembly 31.

[0051] In one embodiment, such as Figure 1 and Figure 2As shown, the first drive plate 312 is slidably connected to the clamping mounting frame 34 along the second direction X, and the second drive plate 313 is slidably connected to the clamping mounting frame 34 along the second direction X, so as to realize the stable movement of the first drive plate 312 and the second drive plate 313 in the second direction X.

[0052] In one embodiment, such as Figure 1 and Figure 2 As shown, a first pad 37 is provided on the side of the first clamping plate 32 near the second clamping plate 33, and a second pad 38 is provided on the side of the second clamping plate 33 near the first clamping plate 32.

[0053] Both the first pad 37 and the second pad 38 are elastic components.

[0054] For example, the first pad 37 and the second pad 38 are silicone blocks.

[0055] By setting a first pad 37 and a second pad 38, both of which are elastic elements, the collision between each clamping plate and the battery 200 can be reduced when clamping the battery 200.

[0056] In one embodiment, such as Figure 1 and Figure 2 As shown, the first pad 37 has a first groove 371 on the side near the second pad 38, and the second pad 38 has a second groove 381 on the side near the first pad 37.

[0057] A clamping space for clamping the battery 200 is formed between the groove wall of the first groove 371 and the groove wall of the second groove 381, so that the battery 200 can be clamped through the clamping space.

[0058] In one embodiment, such as Figure 1 and Figure 2 As shown, the battery flipping device 100 also includes a mounting base 4, on which the linear drive mechanism 1 is mounted.

[0059] The mounting base 4 can be installed on the frame of the coating machine to enable the battery flipping device 100 to be installed on the coating machine.

[0060] In one embodiment, such as Figure 1 and Figure 2 As shown, the mounting base 4 includes a raised base 41, a base plate 42, and a reinforcing rib 43. The base plate 42 is mounted on the raised base 41, and the reinforcing rib 43 is connected between the base plate 42 and the first mounting bracket 11.

[0061] This utility model embodiment also provides a coating machine, which includes a feeding device, a discharging device, a film-applying device, and the aforementioned battery flipping device 100. The feeding device can provide a battery 200 with its large surface facing up in a flat position. The battery flipping device 100 can flip the battery 200 provided by the feeding device from a flat position to an upright position with its top surface facing up. The film-applying device can apply film to the upright battery 200.

[0062] The battery flipping device 100 can also flip the battery 200 with the film applied from an upright position to a flat position, and the unloading device can unload the battery 200 with the film applied and in a flat position.

[0063] The coating machine provided in this embodiment of the utility model first provides a battery 200 in a lying position via a feeding device, then a battery flipping device 100 flips the battery 200 from the lying position to an upright position, and a film-applying device applies film to the upright battery 200. After film application, the battery flipping device 100 flips the film-applied battery 200 back from the upright position to the lying position, and finally, a feeding device unloads the battery. Specifically, when flipping the battery 200, the battery flipping device 100 first clamps the battery 200 along the second direction X via a clamping mechanism 3, and then drives the clamping mechanism 3 to rotate around a flipping axis parallel to the second direction X via a flipping drive mechanism 2, thereby achieving the flipping of the battery 200 clamped in the clamping mechanism 3. During this flipping process, the flipping drive mechanism 2 can be moved along the first direction Z via a linear drive mechanism 1 to adjust the positions of the flipping drive mechanism 2 and the clamping mechanism 3 in the first direction Z. The battery flipping device 100 flips the battery 200 by clamping it first and then flipping it. The action is fast and precise, which can reduce the vibration and impact on the battery 200.

[0064] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
