[0034] The utility model provides a battery shell cutting machine, which includes a transmission member 10, a pressing assembly 30, a cutting assembly 20 and a guide assembly, wherein the transmission member 10 is used to convey a battery 60; the pressing assembly 30 can be raised and lowered above the transmission member 10; the cutting assembly 20 can be movably arranged on one side of the transmission member 10, and the moving direction of the cutting assembly 20 is perpendicular to the transmission direction of the transmission member 10; the guide assembly can be movably arranged on the transmission member 10, and the guide assembly extends along the transmission direction of the transmission member 10.

[0035] The transmission member 10 may adopt a belt transmission module, and the battery 60 may be placed on the belt, and the battery 60 may be driven to move by the rolling of the belt to realize the transportation function.

[0036] A cutting station can be set at any position of the transmission member 10 , and the pressing assembly 30 is installed at the cutting station and is located directly above the transmission member 10 .

[0037] The clamping assembly 30 can be lifted and moved. In the initial state, the clamping assembly 30 rises to a high position. When the battery 60 is transported to the position, that is, transported to the position directly below the clamping assembly 30, the clamping assembly 30 descends until it abuts against the top of the battery 60, and the battery 60 is pressed against the transmission member 10 by the clamping assembly 30, so as to limit the height of the battery 60.

[0038] The guide components are provided on the left and right sides of the transmission member 10 . During the transportation of the battery 60 , the guide components are used to restrict the left and right sides of the battery 60 , thereby preventing the battery 60 from deviating from its transportation direction or falling off the transmission member 10 .

[0039] The guide assembly is movably arranged on the transmission member 10, and the moving direction of the guide assembly is arranged perpendicular to the transmission direction of the transmission member 10. The position of the guide assembly is adjusted so that the edge of the battery 60 fits the guide assembly as much as possible, thereby limiting the battery 60 in its length or width direction.

[0040] Correspondingly, the cutting assembly 20 can be movably arranged on both sides of the transmission member 10 , and the moving direction of the cutting assembly 20 is also perpendicular to the transmission direction of the transmission member 10 .

[0041] In the initial state, the cutting assembly 20 is retracted to the shortest position so that the cutting assembly 20 is separated from the transmission member 10 to avoid interference with the transportation of the battery 60 .

[0042] After the battery 60 is moved into position, the cutting assembly 20 extends out and moves onto the transmission member 10 so as to abut against the battery 60 and cut the battery 60 .

[0043] Among them, by adjusting the expansion and contraction size of the cutting assembly 20 , the cutting position of the cutting assembly 20 on the battery 60 can be more accurately controlled, and the size requirements of different batteries 60 can also be met.

[0044] Specifically, the cutting assembly 20 includes a first driving member 21 and a saw blade 22. The first driving member 21 is arranged on one side of the transmission member 10. The saw blade 22 can be rotatably arranged on the first driving member 21. The first driving member 21 drives the saw blade 22 to approach the transmission member 10 to cut the battery 60. Or, the first driving member 21 drives the saw blade 22 away from the transmission member 10.

[0045] The first driving member 21 may be a lead screw module, which is fixed to the left and / or right side of the transmission member 10. The saw blade 22 is mounted on the lead screw module, and the lead screw module can drive the saw blade 22 to move.

[0046] The driving direction of the lead screw module is perpendicular to the transmission direction of the transmission member 10 . When the lead screw module is extended, the saw blade 22 is driven to move toward the side close to the transmission member 10 .

[0047] The saw blade 22 can be controlled by a motor to achieve high-speed rotation to meet cutting requirements. Correspondingly, the motor for driving the saw blade 22 to rotate can also be installed on the first driving member 21.

[0048] The number of the cutting components 20 can be set to two, which are respectively installed on the left and right sides of the transmission member 10. For different types of batteries 60, the left and right sides of the battery 60 shell can be cut simultaneously by the two cutting components 20.

[0049] The technical solution of the utility model adopts the transmission member 10 to transmit the battery 60, and the length of the battery 60 is limited by the guide assembly; when the battery 60 is transmitted to the right position, the clamping assembly 30 descends to press the battery 60 on the transmission member 10, and the height of the battery 60 is limited by the clamping assembly 30; the cutting assembly 20 extends to cut the shell of the battery 60, and the position of the cutting assembly 20 can be adjusted according to the size of the battery 60, which will meet the size requirements of different batteries 60 and improve the compatibility and flexibility of the equipment.

[0050] The clamping assembly 30 includes a second driving member 31 and a clamping plate 32. The second driving member 31 is arranged above the transmission member 10. The clamping plate 32 is arranged on the second driving member 31. The second driving member 31 drives the clamping plate 32 to descend to clamp the battery 60. Alternatively, the second driving member 31 drives the clamping plate 32 to rise to release the battery 60.

[0051] The clamping assembly 30 can be fixed on the top of the transmission member 10 through a bracket. The second driving member 31 can be a threaded rod, and a threaded hole is set on the external bracket. The threaded rod is rotated to achieve its up and down movement in the threaded hole.

[0052] A twisting flap is installed at the top of the threaded rod to facilitate manual twisting. The clamping plate 32 is installed at the bottom of the threaded rod. When the threaded rod is twisted, the threaded rod moves up and down, and drives the clamping plate 32 to rise and fall. The threaded rod is twisted to make the clamping plate 32 close to the top of the battery 60. The clamping plate 32 cooperates with the transmission member 10 to clamp and fix the battery 60.

[0053] In addition, the threaded rod can also be connected to an external motor, and the motor can drive the threaded rod to rotate. Furthermore, the motor can be connected to an external controller, and a sensor can be installed on the clamping plate 32, and the sensor signal of the sensor can be fed back to the controller, so that the controller can automatically control the lifting and moving of the threaded rod and the clamping plate 32 through feedback adjustment, thereby improving the overall automation of the equipment.

[0054] In addition, the second driving member 31 may also be a screw module or a linear module, for example.

[0055] The guide assembly includes two guide plates 40 . The two guide plates 40 are arranged opposite to each other on both sides of the transmission member 10 . The extending direction of the two guide plates 40 is consistent with the transmission direction of the transmission member 10 .

[0056] The shape of the guide plate 40 is adapted to the shape of the transmission member 10 to ensure that the battery 60 can stably move along the transmission direction of the transmission member 10 during the transmission process. For example, according to different usage scenarios, the transmission member 10 can be arranged in an arc shape or other special shapes to meet the needs of changing the transmission direction of the battery 60. Correspondingly, the shape of the guide plate 40 also changes accordingly.

[0057] A driving mechanism, such as a cylinder, can be installed on the side of the guide plate 40 away from the transmission member 10, and the piston rod of the cylinder is connected to the guide plate 40, thereby driving the guide plate 40 to move. The driving direction of the driving mechanism is perpendicular to the transmission direction of the transmission member 10.

[0058] The guide plates 40 are provided on both the left and right sides of the transmission member 10. The guide plates 40 are moved by a driving mechanism, and the distance between the two guide plates 40 is adjusted to match the size of the battery 60, thereby limiting the left and right directions of the battery 60 and preventing the battery 60 from falling off the transmission member 10.

[0059] The distance between the two guide plates 40 can be adjusted at any time to meet the cutting requirements of batteries 60 of different models and sizes, thereby improving the overall compatibility of the device.

[0060] The battery shell cutting machine further includes a positioning assembly, and the positioning assembly is arranged on the transmission member 10 .

[0061] The positioning assembly includes a plurality of positioning plates 50 , and the plurality of positioning plates 50 are arranged on the transmission member 10 at intervals along the transmission direction of the transmission member 10 .

[0062] The transmission direction of the transmission member 10 is defined as the front, and the side opposite to the transmission direction of the transmission member 10 is defined as the rear. The plurality of positioning plates 50 are arranged at intervals in front and back, and only one battery 60 is placed between any two adjacent positioning plates 50. The positioning plates 50 are used to separate the batteries 60, thereby preventing the batteries 60 from interfering with each other during cutting.

[0063] Furthermore, the positioning assembly is detachably connected to the transmission member 10. The installation position of the top plate can be adjusted so that the distance between two adjacent positioning plates 50 matches the size of the battery 60, thereby limiting the front and rear sides of the battery 60.

[0064] In this embodiment, through the cooperation between the clamping assembly 30, the guide assembly and the positioning assembly, the height, length and width of the battery 60 can be restricted at the same time, which plays a role in fixing the battery 60 and ensures the stability of the battery 60 during the cutting process. At the same time, the positions of the clamping assembly 30, the guide assembly and the positioning assembly are all adjustable, which meets the requirements of different battery 60 sizes and improves the compatibility and flexibility of battery 60 cutting.
