Description

Technical Field

[0001] The utility model relates to the technical field of production devices, in particular to a battery shell production device. Background Art

[0002] Generally, power batteries use battery cases to protect the battery cells. After the battery case is produced, the battery cells are loaded into it, and finally the cap is installed and packaged to protect the battery. At present, when the battery case is produced, a cutting device is needed to cut the open end of the battery case to a suitable size, and then the battery cell is filled into the battery case, and then the open end of the battery case is sealed to form a complete battery.

A liftable mounting plate 400 is provided in the mounting cavity, and a cutting blade 411 is provided on the mounting plate 400 through a motor 410. A driving assembly for driving the mounting plate 400 to lift and lower so that the cutting blade 411 extends out of the cutting notch 102 is also provided in the mounting cavity.

[0025] In this embodiment, the clamping assembly 120 is arranged at one side of the operating table 101, and the battery housing 110 is fixed by the clamping assembly 120, so that it can be fixed on the operating table 101. When it is actually used, the clamping assembly 120 fixes the battery housing 110 so that one end of the battery housing 110 can extend to the cutting notch 102. At this time, the driving assembly can drive the mounting plate 400 to rise and fall in the mounting cavity, thereby realizing that the cutting blade 411 extends from the cutting notch 102, wherein the center position of the cutting blade 411 is fixedly mounted on the output shaft of the motor 410, thereby enabling the motor 410 to drive the cutting blade 411 to rotate, so as to cut the battery housing 110, so that one end of the battery housing 110 is cut to a suitable size, thereby facilitating the subsequent packaging of the battery;

[0026] In actual use, the clamping assembly 120 is moved on the operating table 101, so that when cutting the battery housing 110, the clamping assembly 120 is pushed to move slowly along the direction of the cutting notch 102, so that the battery housing 110 can be fed along the rotation direction of the cutting blade 411, so that the battery housing 110 can be cut better;

[0027] Among them, the opening of the installation cavity is set toward the other side of the operating table 101, and a side door 130 that can be opened and closed is set at the opening through a hinge. The opening and closing of the side door 130 can better facilitate the disassembly and assembly of the installation plate 400, the motor 410, the cutting blade 411 and the drive assembly in the installation cavity.

[0028] Combination Figure 2-3 As shown, in this embodiment, the clamping assembly 120 includes a base 121, and the upper side surface of the base 121 is relatively provided with a first slide groove 201 along its moving direction, and the upper side surface of the base 121 is perpendicular to the first slide groove 201 and is provided with a second slide groove 202 that penetrates the first slide groove 201; a slidable first slider 310 is relatively provided in the first slide groove 201, and a second slider 210 is slidably provided in the second slide groove 202, and a hinged connecting rod 220 is hingedly provided between the second slider 210 and the corresponding first slider 310, and a clamping plate 230 is relatively provided on the base 121 and is located on both sides of the second slide groove 202, and the clamping plate 230 is connected to the corresponding first slider 310 through a connecting plate 231, and the second slider 210 is located in the second slide groove 202 and slides to drive the hinged connecting rod 220 to pull the first slider 310 closer or farther away from each other, so as to realize the clamping of the battery housing 110 by the clamping plate 230.

[0029] In actual use, in order to better realize the smooth sliding of the first slider 310 in the first slide groove 201, the first slide groove 201 is provided with first limiting grooves 203 on the opposite side walls along its extension direction, and the first slider 310 is provided with a first limiting block extending into the corresponding first limiting groove 203 for sliding. In order to better realize the smooth sliding of the second slider 210 in the second slide groove 202, the second slide groove 202 is provided with second limiting grooves 204 on the opposite side walls along its extension direction, and the second slider 210 is provided with a second limiting block extending into the corresponding second limiting groove 204 for sliding.

[0030] The two hinged connecting rods 220 on the same side of the second slide groove 202 are arranged in parallel, and the hinged connecting rods 220 on both sides of the second slide groove 202 are arranged symmetrically, so that the second slider 210 can slide back and forth in the second slide groove 202, and can pull the hinged connecting rod 220 to drive the first slider 310 to move relatively in the first slide groove 201, wherein the clamping plate 230 is connected to the corresponding first slider 310 through the connecting plate 231, so that the relative movement of the first slider 310 in the first slide groove 201 can drive the two clamping plates 230 to move closer to or away from each other, thereby completing the clamping and fixing of the battery housing 110;

[0031] Among them, Figure 2 As shown, in order to enable the clamping plate 230 to stably clamp the battery housing 110, the two opposite sides of the clamping plate 230 are bent to form a bent portion that covers the side of the battery housing 110, thereby limiting the position of the battery housing 110 so that it can be stably clamped and fixed;

[0032] In actual use, the two ends of the articulated link 220 are rotatably mounted on the corresponding first slider 310 and second slider 210 respectively through the articulated shaft, thereby preferably realizing the articulated connection of the two ends of the articulated link 220.

[0033] In this embodiment, a rotatable first screw rod 320 is disposed in the second slide groove 202 along its extension direction. The first screw rod 320 is threadedly passed through the second slider 210 , and one end of the first screw rod 320 extends out of the base 121 .

[0034] In this embodiment, the second limit block and the second limit groove 204 are used to coordinately limit the second slider 210 in the second slide groove 202. Since the first screw rod 320 is threaded through the second slider 210, the rotation of the first screw rod 320 can drive the second slider 210 to reciprocate in the second slide groove 202, thereby realizing the relative movement of the clamping plate 230.

[0035] Among them, both ends of the first screw rod 320 are rotatably installed in the second slide groove 202 through the bearing seat, thereby realizing the rotatable installation of the first screw rod 320 in the second slide groove 202. Among them, in order to facilitate the operator to drive the first screw rod 320 to rotate, one end of the first screw rod 320 is extended out of the base 121, and the extended end of the first screw rod 320 is provided with a first hand-cranked wheel 321. Through the setting of the first hand-cranked wheel 321, it is better for the operator to drive the first screw rod 320 to rotate, thereby controlling the clamping assembly 120 to clamp the battery shell 110.

[0036] In this embodiment, a sliding groove 103 with a T-shaped cross section is provided on the operating table 101 along the moving direction of the clamping assembly 120 , and a sliding block 205 is provided on the lower side of the base 121 and slides in the corresponding sliding groove 103 .

[0037] In this embodiment, the sliding groove 103 and the sliding block 205 are matched to achieve the sliding of the base 121 on the operating table 101;

[0038] Among them, in order to facilitate the operator to push the base 121 to move, a handle 240 is provided on the upper side of the base 121 for pushing the base 121 to slide. At the same time, in order to prevent the sliding block 205 from sliding out of the sliding groove 103, blocking blocks (not shown in the figure) are installed at the ends of the sliding groove 103, thereby preventing the clamping assembly 120 from sliding out of the operating table 101.

[0039] Combination Figure 4 As shown, in this embodiment, the driving assembly includes a second screw rod 420 that is rotatable and passes through both ends of the mounting plate 400, a sprocket 421 is provided on the second screw rod 420 and near the lower end, a chain 422 is sleeved between the sprocket wheels 421, and the upper end of one of the two second screw rods 420 is extended out of the operating table 101.

[0040] In actual use of this embodiment, both ends of the second screw rod 420 are rotatably installed in the installation cavity through the bearing seat, thereby preferably realizing the rotatable installation of the second screw rod 420 in the installation cavity;

[0041] Among them, through the arrangement of the sprocket 421 and the chain 422, the two second screw rods 420 can rotate synchronously through the cooperation of the two, thereby realizing the lifting and lowering adjustment of the mounting plate 400 in the mounting cavity;

[0042] In order to facilitate the operator to drive the second screw rod 420 to rotate outside the cabinet 100, the upper end of one of the two second screw rods 420 is extended outside the operating table 101, and a second hand-cranked wheel 423 is provided at the extended end of the second screw rod 420.

[0043] Working principle: By rotating the first hand-cranked wheel 321 to rotate the first screw rod 320, the clamping plates 230 are driven to move away from each other, the battery housing 110 is placed between the clamping plates 230, and the first hand-cranked wheel 321 is rotated to rotate the first screw rod 320, and the clamping plates 230 are driven to move closer to each other to clamp and fix the battery housing 110, and then the second hand-cranked wheel 423 is rotated to drive the second screw rod 420 to rotate, so that the cutting blade 411 extends out of the cutting notch 102, and then the motor 410 is started to drive the cutting blade 411 to rotate, and the handle 240 drives the base 121 to move slowly, so that the battery housing 110 is slowly fed toward the cutting blade 411, so that the cutting blade 411 cuts the battery housing 110 into a suitable size, which is convenient for subsequent battery packaging.

[0044] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
