[0043] A material unloading device and a battery cell shelling machine according to an embodiment of the utility model are described below in conjunction with the accompanying drawings.

[0044] The utility model aims to provide an embodiment of a battery core shelling machine. In addition, the utility model also aims to provide an embodiment of a material unloading device of the battery core shelling machine.

[0045] Taking into account the versatility of the blanking device, the utility model aims to provide a blanking device, which is mainly used to convert a column product from an upright state or an inclined state to a lying state, or, to convert a column product from a lying state to an upright state or an inclined state, or, moreover, to switch a column product between the three states of upright, lying and inclined.

[0046] Reference Figure 1 The utility model aims to provide an embodiment of a feeding device of a battery core shelling machine.

[0047] Among them, the main parts of the battery cell shelling machine can refer to the patent application document with the patent application name of Battery Cell Shelling Machine, application number 202210281782.5, application date March 22, 2022, application publication number CN114695947A, and application publication date July 1, 2022, and will not be described in detail.

[0048] It can be learned that the unloading position of the battery cell shelling machine provides an upright round rod battery, that is, the product to be unloaded.

[0049] Reference Figure 1 The battery cell shelling machine has a feeding device, which takes the battery off the turntable 21 of the battery cell shelling machine and places it on the conveyor belt below the feeding device to facilitate the battery transportation.

[0050] Reference Figure 2 As for the unloading device, the unloading device includes a clamping mechanism 1, a transmission mechanism 2 and a driving mechanism 6.

[0051] The clamping mechanism 1 can clamp and release the product to be unloaded. In some specific embodiments of the present invention, the clamping mechanism 1 can include two clamping claws 17, and the two clamping claws 17 can move closer to or farther from each other to clamp or release the product to be unloaded.

[0052] It is easy to understand that the present embodiment sets up a clamping mechanism 1, so that it can not only clamp the product to be unloaded to facilitate the removal of the product to be unloaded from the unloading position to prevent the product to be unloaded from falling, but also release the product to be unloaded so that the product to be unloaded is located in the discharge position to meet the unloading needs.

[0053] In some specific embodiments of the present invention, two clamping claws 17 can be installed on the centering cylinder, so that the two clamping claws 17 can clamp the product to be unloaded in a centering manner.

[0054] In some specific embodiments of the present invention, the unloading device may further include a limit plate 19, which is provided with a snap-in 20. The snap-in 20 is located at the unloading position, and the snap-in 20 can accommodate two claws 17 and limit the two claws 17 from moving away from each other, so that the product to be unloaded can be accommodated between the two claws 17 and prevented from falling out.

[0055] That is, when the two claws 17 move away from each other, the inner side of the clamping opening 20 abuts against the two claws 17, preventing the two claws 17 from moving further away from each other, so that the space between the two claws 17 is moderate, which makes it convenient for the product to be unloaded to rise and enter between the two claws 17, and prevents the product to be unloaded from tipping over due to lack of limit.

[0056] In some specific embodiments of the present invention, when the claw 17 is in the unloading position, a chamfered surface 18 can be provided at the bottom of the claw 17. The chamfered surface 18 guides the product to be unloaded between the two claws 17 to prevent the product to be unloaded from touching the edge of the claw 17 and being damaged.

[0057] In some specific embodiments of the present invention, the chamfered surfaces 18 of the two claws 17 can be matched to form a cone shape to achieve multi-directional guidance.

[0058] The transmission mechanism 2 includes a frame 3, a rotating seat 4 arranged on the frame 3, and a sliding rod 5 arranged on the rotating seat 4. The material clamping mechanism 1 is arranged at one end of the sliding rod 5.

[0059] It is easy to understand that in this embodiment, the transmission mechanism 2 is arranged so that the transmission mechanism 2 includes a frame 3, a swivel seat 4 and a sliding rod 5. Therefore, the composite activity of the clamping mechanism 1 can be realized by the rotation of the swivel seat 4 and the sliding of the sliding rod 5 relative to the swivel seat 4, eliminating the conventional translation mechanism, lifting mechanism and rotation mechanism, which is beneficial to reduce manufacturing costs and reduce occupied space.

[0060] Since the translation mechanism and the lifting mechanism have a translation stroke and a lifting stroke, the translation mechanism and the lifting mechanism will occupy the space at the top of the battery cell shelling machine, which is inconvenient for arranging other processing equipment of the battery cell shelling machine. Therefore, the diameter of the turntable 21 needs to be increased, which increases the occupied space of the battery cell shelling machine. The present embodiment omits the translation mechanism and the lifting mechanism, which is beneficial to reducing the occupied space, making the battery cell shelling machine small in size and convenient for arrangement. At the same time, it also saves the cost of manufacturing the translation mechanism and the lifting mechanism.

[0061] At the same time, combined Figure 1 and Figure 2 It can be seen that the present embodiment also omits the rotating mechanism that directly drives the clamping mechanism 1 to rotate with the motor 9, thereby reducing the circumferential space occupied by the turntable 21 of the battery cell shelling machine, further freeing up space, facilitating the arrangement and adjustment of the battery cell shelling machine, and helping to reduce the occupied space, making the battery cell shelling machine structure more compact.

[0062] In some specific embodiments of the present invention, the sliding rod 5 may include a linear guide rail, thereby preventing the sliding rod 5 from rotating and affecting material feeding. At the same time, the linear guide rail is a standard part that is easy to purchase and has a low manufacturing cost.

[0063] In some specific embodiments of the present invention, a bearing or the like may be provided between the rotating seat 4 and the frame 3 to reduce the wear caused by the rotation of the rotating seat 4 .

[0064] As for the driving mechanism 6 , the driving mechanism 6 mainly includes a driving pin 7 , a driving track 8 and a motor 9 .

[0065] The driving pin 7 is fixed to the other end of the sliding rod 5 , and the driving track 8 and the motor 9 are arranged on the frame 3 .

[0066] In detail, the output shaft of the motor 9 is connected to the swing arm 10, and the swing arm 10 is provided with a radial waist hole 11. The radial waist hole 11 and the driving path 8 are both used to accommodate the driving pin 7. When the motor 9 drives the swing arm 10 to rotate, the inner surface of the radial waist hole 11 abuts against the driving pin 7, so that the driving pin 7 moves along the driving path 8.

[0067] It is easy to understand that in this embodiment, the driving mechanism 6 is provided, and the driving mechanism 6 includes a motor 9, a driving pin 7 and a driving track 8. The driving pin 7 is located on the driving track 8, and the driving pin 7 is fixed on the sliding rod 5. Therefore, when the motor 9 drives the swing arm 10 to rotate, the swing arm 10 can move the driving pin 7, so that the driving pin 7 moves along the driving track 8, and then the sliding rod 5 and the swivel seat 4 rotate and move accordingly to complete the unloading action.

[0068] It is easy to understand that in this embodiment, the swing arm 10 is provided with a radial waist hole 11. Therefore, it can not only meet the need to move the driving pin 7, but also make different positions of the radial waist hole 11 abut the driving pin 7 without causing the failure of the movement. It is also convenient for the swing arm 10 to turn the direction to move the driving pin 7, so that the unloading device can continue to unload.

[0069] As for the driving track 8 , the driving track 8 includes a translation section 12 , a lifting section 13 and a connecting section 14 .

[0070] The translation section 12 is used to accommodate the translation of the driving pin 7 to drive the sliding rod 5 to slide relative to the rotating seat 4, so that the clamping mechanism 1 is close to or away from the unloading position of the product to be unloaded.

[0071] The lifting section 13 is used to accommodate the lifting of the driving pin 7 to drive the sliding rod 5 to slide relative to the rotating seat 4, so that the clamping mechanism 1 is close to or away from the discharge position of the product to be discharged;

[0072] The connecting section 14 connects the translation section 12 and the lifting section 13 to drive the sliding rod 5 and the rotating seat 4 to rotate together, so that the driving pin 7 switches between the translation section 12 and the lifting section 13 .

[0073] It is easy to understand that in this embodiment, the driving track 8 is provided so that the driving track 8 has a translation section 12, a lifting section 13 and a connecting section 14. Therefore, the clamping mechanism 1 can be translated, lifted and rotated, and the movement trajectory of the clamping mechanism 1 is strictly limited to meet the unloading requirements.

[0074] It should be noted that the translation section 12 and the lifting section 13 are limitations on functional results. Whether the translation section 12 and the lifting section 13 are horizontal, vertical, or inclined is determined based on the center of the swivel seat 4 and the actual required motion trajectory.

[0075] In some specific embodiments of the present invention, the lifting section 13 can be arranged above the swivel seat 4, the translation section 12 can be arranged on the horizontal side of the swivel seat 4, and the connecting section 14 connects the lifting section 13 and the translation section 12 at one end away from the swivel seat 4. The connecting section 14 is a circular ring section, and the center of the circular ring section is arranged close to the swivel seat 4.

[0076] It is easy to understand that the driving track 8 is formed in the above manner in this embodiment, and the structure is simple and easy to manufacture.

[0077] In some specific embodiments of the present invention, the lifting section 13 and the rotating seat 4 can be inverted, but the height and material consumption of the frame 3 will be increased.

[0078] In some specific embodiments of the present invention, the motor 9 can be fixed on the entity surrounded by the driving track 8 on the frame 3.

[0079] It is easy to understand that, in this embodiment, by fixing the motor 9 on the entity surrounded by the drive track 8 on the frame 3, the swing arm 10 can smoothly drive the drive pin 7 to switch between the sections, thereby reducing movement resistance and contributing to the miniaturization of the unloading device.

[0080] In some specific embodiments of the present invention, the radial waist hole 11 may be disposed between the driving track 8 and the sliding rod 5 .

[0081] It is easy to understand that, in this embodiment, the swing arm 10 and the sliding rod 5 are located on the same side of the frame 3 to facilitate assembly.

[0082] In some specific embodiments of the present invention, the frame 3 may include a vertical plate, and the vertical plate is provided with a driving track 8, and the driving track 8 connects two sides of the vertical plate in the thickness direction.

[0083] It is easy to understand that, in this embodiment, by connecting the driving path 8 to both sides of the vertical plate in the thickness direction, it is also convenient to disassemble and assemble the driving pin 7 and facilitate maintenance. At the same time, it also helps to simplify the frame 3 and reduce the manufacturing cost of the frame 3.

[0084] In some specific embodiments of the present invention, the clamping mechanism 1 can include a mounting plate 15 connected to the sliding rod 5 and a mounting block 16 connected to the mounting plate 15. The mounting block 16 is provided with a clamping assembly, which is used to clamp the product to be unloaded, and the clamping assembly is offset relative to the sliding rod 5.

[0085] It is easy to understand that, in this embodiment, by providing the mounting plate 15 and the mounting block 16, the position of the clamping assembly can be reasonably installed to reduce subsequent adjustments.

[0086] In some specific embodiments of the present invention, the clamping mechanism 1 may include a mounting plate 15 connected to the sliding rod 5, and a mounting block 16 obliquely connected to the mounting plate 15. The mounting block 16 is provided with a clamping assembly for clamping the product to be unloaded.

[0087] It is easy to understand that this embodiment, by tilting the mounting block 16 to connect the mounting plate 15, can, on the one hand, adapt to the arrangement requirement that the rotating surface of the clamping mechanism 1 does not pass through the center of the turntable 21, which helps to reduce the horizontal occupied space of the battery cell shelling machine; on the other hand, it also allows the two claws 17 to make the product to be unloaded roll down when unloading, avoiding falling and protecting the product to be unloaded.

[0088] In addition, the material clamping assembly can be prevented from touching the edge of the clamping port 20 when the rotating surface of the material clamping mechanism 1 does not pass through the center of the turntable 21 .

[0089] In some specific embodiments of the present invention, the mounting block 16 can be connected to the mounting plate 15 in an inclined manner. Specifically, the mounting block 16 shown in the figure is triangular, which is convenient for connecting the mounting plate 15 and the centering cylinder.

[0090] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0091] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
