DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 5 As shown, an automatic unloading device for new energy vehicle batteries according to an embodiment of the present invention comprises a working frame 1, a conveyor belt 11 is arranged at the top of the working frame 1, a pair of first hydraulic cylinders 2 are arranged symmetrically based on the center at the top of the working frame 1, a first connecting member 21 is arranged at the end of the output end of the first hydraulic cylinder 2, a clamping plate 22 is arranged at one end of the first connecting member 21 away from the first hydraulic cylinder 2, and the bottom end of the clamping plate 22 is not in contact with the conveyor belt 11;

[0032] In actual battery shell operations, when the battery shell is transported to a specified position, a plurality of battery blocks need to be filled into the interior of the battery shell by a manipulator. During the filling process, the battery shell is prone to move, which affects the position change of the battery shell and further affects the filling stability of the battery shell. To solve the above problems, the embodiment of the present invention provides a clamping plate 22. When in use, the battery shell is placed on the surface of the conveyor belt 11, and the conveyor belt 11 transports the battery shell to a specified position, and then the battery blocks are filled. When the battery shell stops, the first hydraulic cylinder 2 is started, and the output end of the first hydraulic cylinder 2 drives the clamping plate 22 to move toward the battery shell transported on the conveyor belt 11 through the first connecting member 21. After the clamping plate 22 fixes the battery shell, it stops moving, and then the battery blocks are filled into the battery shell. In this process, the battery shell is restricted and cannot move, so it will not move, ensuring the stability of the battery shell filled with battery blocks. After the battery shell is filled, the clamping restriction on the battery shell is released, and it continues to be transported through the conveyor belt 11, and then it is unloaded at the unloading end.

[0033] like Figures 2 to 8As shown, an annular notch 23 is provided on the side of the clamping plate 22, and a rotating belt 32 is slidably connected inside the annular notch 23, and a driving shaft 30 is inserted inside the rotating belt 32, and the axial surface of the driving shaft 30 is pressed and contacted with the inner surface of the rotating belt 32; a driving motor 3 is arranged above the driving shaft 30, and a second connecting member 31 is arranged between the driving motor 3 and the clamping plate 22, and the bottom end of the output end of the driving motor 3 is connected with the top end of the driving shaft 30; a baffle 24 is arranged at the end of the clamping plate 22 facing the conveyor belt 11 for feeding; when the clamping plate 22 clamps and fixes the battery shell, the driving motor 3 is started, and the driving motor 3 drives the driving shaft 30 to rotate, and the axial surface of the driving shaft 30 is pressed and contacted with the inner surface of the rotating belt 32, and as the driving motor 31 is driven, the driving motor 3 is driven to rotate. The driving shaft 30 rotates, and the driving shaft 30 drives the rotating belt 32 to rotate through the friction force. The rotating belt 32 rotates in the annular notch 23, and when the clamping plate 22 clamps the battery shell, the surface of the rotating belt 32 presses against the side of the battery shell. Therefore, as the rotating belt 32 rotates, the rotating belt 32 can drive the battery shell to move through the friction force, and stop when the battery shell is blocked by the baffle 24; after the conveyor belt 11 conveys the battery shell, the position can be further adjusted by the rotating belt 32, so as to accurately fill the battery shell and ensure the accuracy of the battery shell filling; it should be pointed out that part of the rotating belt 32 is located outside the annular notch 23; when the clamping plate 22 clamps the battery shell, the surface of the rotating belt 32 presses against the battery shell first.

[0034] A pair of limit frames 4 are symmetrically arranged on the side of the clamping plate 22 and based on the driving shaft 30. The limit frames 4 are used to limit the rotating belt 32 so that the rotating belt 32 is in full contact with the driving shaft 30. A buffer shaft 41 is arranged for internal rotation of the limit frame 4. The axial surface of the buffer shaft 41 is in contact with the surface of the rotating belt 32. The pair of limit frames 4 can limit the position of the rotating belt 32 so that the rotating belt 32 is in full contact with the driving shaft 30, which is beneficial to improving the transmission effect of the driving shaft 30 on the rotating belt 32. In addition, a buffer shaft 41 is arranged for internal rotation of the limit frame 4. The axial surface of the buffer shaft 41 is in contact with the surface of the rotating belt 32. The setting of the buffer shaft 41 can reduce the friction between the rotating belt 32 and the limit frame 4, so as to avoid excessive friction between the rotating belt 32 and the limit frame 4 affecting its own rotation.

[0035] The second connecting member 31 includes a mounting frame 311, and the driving motor 3 is mounted on the mounting frame 311; a pair of linkage plates 312 are symmetrically arranged on both sides of the mounting frame 311, and a linkage rod 313 is arranged on the side of the linkage plate 312 facing the clamping plate 22, and the end of the linkage rod 313 away from the linkage plate 312 passes through the interior of the clamping plate 22; an air spring 314 is arranged between the linkage plate 312 and the clamping plate 22; when the driving motor 3 is in use, the air spring 314 continuously applies an extrusion force to the driving motor 3 through the linkage plate 312 and the mounting frame 311, so that the driving motor 3 drives the driving shaft 30 and the rotating belt 32 to maintain a continuous pressing state; reducing the influence of the loosening of the rotating belt 32 on the use; and because the end of the linkage rod 313 away from the linkage plate 312 passes through the interior of the clamping plate 22, the movement of the driving motor 3 remains linear, and the position between the corresponding driving shaft 30 and the rotating belt 32 remains stable.

[0036] The air inlet of the air spring 314 is connected to a first hose 315, and the first hose 315 is externally connected to a first air pump; when the rotating belt 32 is used for a period of time and becomes loose, the air spring 314 is inflated by the first air pump and the first hose 315, so that the air spring 314 further expands, and cooperates with the linkage plate 312 and the mounting frame 311 to enable the driving motor 3 to drive the driving shaft 30 to increase the pressure against the rotating belt 32, thereby ensuring the pressure between the driving shaft 30 and the rotating belt 32, and ensuring the transmission effect between the driving shaft 30 and the rotating belt 32.

[0037] The first connecting member 21 includes a cylinder 211; the cylinder 211 is installed on the side of the clamping plate 22, and the piston 212 is slidably connected inside the cylinder 211. A push rod 213 is provided on the side of the piston 212 facing the first hydraulic cylinder 2, and the end of the push rod 213 away from the piston 212 is connected to the output end of the first hydraulic cylinder 2; a pressure relief valve 215 is provided on one side of the cylinder 211; when the clamping plate 22 clamps the battery shell, the pressure of the clamping plate 22 on the battery shell is the internal pressure of the cylinder 211, and the cylinder 211 is connected to the pressure relief valve 215, so as the push rod 213 drives the piston 212 to move into the cylinder 211, the pressure in the cylinder 211 increases. When it increases to a certain size, the pressure relief valve 215 will leak the gas inside the cylinder 211, so the upper limit of the internal pressure of the cylinder 211 is limited, and the upper limit of the pressure of the clamping plate 22 on the battery shell is limited, so as to prevent the battery shell from being damaged by excessive compression.

[0038] The other side of the cylinder 211 is connected to a second hose 214, which is externally connected to a second air pump; before the next clamping, the cylinder 211 is continuously inflated through the second air pump and the second hose 214, so that the gas pressure inside the cylinder 211 is continuously maintained at a constant level, ensuring the continuity of use of the cylinder 211.

[0039] A pair of guiding plates 5 are provided at the end of the clamping plate 22 facing the unloading conveyor belt 11; the guiding plate 5 is used to guide the battery shell conveyed by the conveyor belt 11; when the conveyor belt 11 conveys the battery shell, the guiding plate 5 at the end of the clamping plate 22 can guide the battery shell to avoid the battery shell being blocked by the end of the clamping plate 22 when moving, thereby ensuring the smooth movement of the battery shell.

[0040] The surface of the receiving plate 5 is covered with a layer of lubricating film; when the receiving plate 5 receives the battery housing, the lubricating film on the surface of the receiving plate 5 can reduce the friction between the battery housing and the receiving plate 5, which is beneficial to improve the smoothness of the receiving.

[0041] The lead plate 5 is made of elastic material; when the lead plate 5 is connected to the battery housing, a certain deformation may occur, which provides a buffer for the contact between the lead plate 5 and the battery housing, and is beneficial to protecting the battery housing.

[0042] During operation, the battery shell is placed on the surface of the conveyor belt 11, and the conveyor belt 11 transports the battery shell to a designated position, and then the battery block is filled. When the battery shell stops, the first hydraulic cylinder 2 is started, and the output end of the first hydraulic cylinder 2 drives the clamping plate 22 to move toward the battery shell transported on the conveyor belt 11 through the first connecting member 21, and stops moving after the clamping plate 22 fixes the battery shell, and then the battery block is filled into the battery shell. In this process, the battery shell is restricted and cannot move, so it will not move, ensuring the stability of the battery shell filling the battery block; after the battery shell is filled, the clamping restriction on the battery shell is released, and the conveyor belt 11 continues to convey it, and then it is unloaded at the unloading end; wherein when the clamping plate 22 clamps and fixes the battery shell, the drive motor 3 is started, and the drive motor 3 drives the drive shaft 30 to rotate, and the axial surface of the drive shaft 30 is pressed and contacted with the inner surface of the rotating belt 32. As the drive shaft 30 rotates, the drive shaft 30 drives the rotating belt 32 to rotate through friction, and the rotating belt 32 rotates in the annular notch 23, and When the clamping plate 22 clamps the battery shell, the surface of the rotating belt 32 presses against the side of the battery shell. Therefore, as the rotating belt 32 rotates, the rotating belt 32 can drive the battery shell to move by friction, and stop when the battery shell is blocked by the baffle 24; after the conveyor belt 11 conveys the battery shell, the position can be further adjusted by the rotating belt 32, thereby accurately filling the battery shell and ensuring the accuracy of the battery shell filling; it should be pointed out that part of the rotating belt 32 is located on the outside of the annular notch 23; when the clamping plate 22 clamps the battery shell, the surface of the rotating belt 32 presses against the battery shell first; wherein; a pair of limit frames 4 can limit the position of the rotating belt 32, so that the rotating belt 32 is fully in contact with the drive shaft 30, which is beneficial to improve the transmission effect of the drive shaft 30 on the rotating belt 32; in addition, a buffer shaft 41 is arranged through the internal rotation of the limit frame 4; the axial surface of the buffer shaft 41 is in contact with the surface of the rotating belt 32, and the setting of the buffer shaft 41 can reduce the friction between the rotating belt 32 and the limit frame 4, and avoid the excessive friction between the rotating belt 32 and the limit frame 4 affecting its own rotation.

[0043] When the driving motor 3 is in use, the air spring 314 continuously applies a squeezing force to the driving motor 3 through the linkage plate 312 and the mounting bracket 311, so that the driving motor 3 drives the driving shaft 30 and the rotating belt 32 to maintain a pressing state, thereby reducing the influence of the loosening of the rotating belt 32 on the use; and because the end of the linkage rod 313 away from the linkage plate 312 passes through the inside of the clamping plate 22, the movement of the driving motor 3 remains linear, and the corresponding position between the driving shaft 30 and the rotating belt 32 remains stable; wherein, when the rotating belt 32 is used for a period of time and becomes loose, the first air pump The air spring 314 is inflated with the first hose 315, so that the air spring 314 is further expanded, and the linkage plate 312 and the mounting bracket 311 are cooperated to make the driving motor 3 drive the driving shaft 30 to increase the pressure against the rotating belt 32, thereby ensuring the pressure between the driving shaft 30 and the rotating belt 32, and ensuring the transmission effect between the driving shaft 30 and the rotating belt 32; wherein when the clamping plate 22 clamps the battery shell, the pressure of the clamping plate 22 on the battery shell is the internal pressure of the cylinder 211, and the cylinder 211 is connected to the pressure relief valve 215, so as the push rod 213 drives the active The plug 212 moves toward the inside of the cylinder 211, and the pressure in the cylinder 211 increases. When it increases to a certain level, the pressure relief valve 215 will leak the gas inside the cylinder 211, so the pressure inside the cylinder 211 is limited, and the pressure of the clamping plate 22 on the battery shell is limited, so as to prevent the battery shell from being damaged by excessive compression; before the next clamping, the second air pump and the second hose 214 are used to continuously inflate the cylinder 211, so that the gas pressure inside the cylinder 211 is continuously maintained at a constant level, so as to ensure the continuity of the use of the cylinder 211; when the conveyor belt 11 is transporting the battery shell, the clamping plate 214 is used to continuously inflate the cylinder 211, so as to ensure the continuity of the use of the cylinder 211; when the conveyor belt 11 is transporting the battery shell, the clamping plate 214 is used to continuously inflate the cylinder 211, so as to ensure the continuity of the use of the cylinder 211; The receiving plate 5 at the end of the plate 22 can receive the battery shell to prevent the battery shell from being blocked by the end of the clamping plate 22 when moving, thereby ensuring the smooth movement of the battery shell; wherein the surface of the receiving plate 5 is covered with a layer of lubricating film; when the receiving plate 5 receives the battery shell, the lubricating film on the surface of the receiving plate 5 can reduce the friction between the battery shell and the receiving plate 5, which is beneficial to improving the smoothness of the connection; wherein the receiving plate 5 is made of elastic material; when the receiving plate 5 receives the battery shell, a certain deformation may occur, thereby providing a buffer for the contact between the receiving plate 5 and the battery shell, which is beneficial to protecting the battery shell.
