DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figure 1 — Figure 4As shown, the present invention provides: a cylindrical lithium battery cap packaging machine, including a workbench 1, a lithium battery loading assembly 2 and a cap loading assembly 3, the workbench 1 is provided with a conveyor belt 11 extending along the length direction of the workbench 1, and a plurality of transport assemblies are distributed on the conveyor belt 11 along its movement path, the transport assembly includes a fixed block 12 arranged on both sides of the conveyor belt 11 and a positioning plate 13 fixed between the two fixed blocks 12, and a plurality of battery limiting columns are arranged on the positioning plate 13 along its length direction, the cap loading assembly 3 is arranged in the middle of the workbench 1, the cap loading assembly 3 is used to place the cap on the lithium battery, and the tail of the workbench 1 is provided with a pressing assembly 14 for pressing the cap onto the lithium battery; the lithium battery loading assembly 2 includes a first A platform 21, a connecting rod 22, a first motor 23 and a cam 24; the first platform 21 is arranged on the front side of the workbench 1, and the first platform 21 is provided with a first material transport channel 211 corresponding to each battery limiting column, and the bottom of the tail end of the first material transport channel 211 is provided with a through hole; the connecting rod 22 is arranged at the bottom of the first platform 21, and the top of the connecting rod 22 is provided with a convex shaft that fits with the clearance of the through hole; the first motor 23 is arranged at the bottom of the first platform 21; the cam 24 is arranged on the output shaft of the first motor 23, and the cam 24 and the bottom end of the connecting rod 22 abut against each other; the lithium battery loading assembly 2 also includes a swing assembly 25 for placing the lithium battery on the first material transport channel 211 into the battery limiting column, and the swing assembly 25 is arranged at the front end of the workbench 1.

[0034] The lithium battery is continuously moved to each first material transport channel 211 by an external device until the lithium battery moves to the tail end of the first material transport channel 211, and then the first motor 23 starts to work and drives the cam 24 to rotate, thereby pushing the connecting rod 22 to move upward, and then driving the lithium battery at the tail end of the first material transport channel 211 to extend out of the first material transport channel 211. At this time, the swing mechanism clamps the extended lithium battery, and then puts the lithium battery into the battery limit column of the positioning plate 13, and then the swing mechanism returns to the first platform 21 to clamp the subsequent lithium battery. When the lithium battery is placed in the battery limit column, the swing mechanism is turned back to the first platform 21. After being positioned inside the column, the positioning plate 13 is driven by the conveyor belt 11 to move backward, thereby moving the subsequent positioning plate 13 to the previous position, so that the swing assembly 25 can continue to place the lithium battery on the subsequent transport assembly, and the positioning plate 13 moves with the lithium battery to the bottom of the cap loading assembly 3, and then the cap loading assembly 3 places the cap on the lithium battery, and then the positioning plate 13 is driven by the conveyor belt 11 to move to the bottom of the pressing assembly 14, and the cap placed on the lithium battery is installed on the lithium battery through the pressing assembly 14, thereby completing the packaging of the lithium battery.

[0035] Reference Figure 5As shown: a connecting shaft 121 is provided at the connection between the fixing block 12 and the positioning plate 13; through holes 131 that cooperate with the connecting shaft 121 are provided on both sides of the positioning plate 13; a locking nut 15 is threadedly connected to the connecting shaft 121, and the bottom end of the locking nut 15 abuts against the top end of the positioning plate 13.

[0036] The fixing blocks 12 are respectively arranged on both sides of the conveyor belt 11, and the top plate is placed on the fixing blocks 12 through the through holes 131 on both sides, and then the locking nut 15 is matched with the thread of the connecting shaft 121 to fix the positioning plate 13 between the two fixing blocks 12, ensuring that after the lithium battery is placed on the battery limit column, the conveyor belt 11 can smoothly drive the positioning plate 13 to move. At the same time, due to the detachable fixed connection between the positioning plate 13 and the fixing block 12, the positioning plate 13 can be quickly disassembled for maintenance and repair after long-term use, thereby extending the service life of the equipment.

[0037] Reference Figure 6 As shown: the swing assembly 25 includes a swing arm 251, a rotating shaft 252 and a support plate 253; the swing arm 251 has two and is relatively arranged on both sides of the conveyor belt 11; the rotating shaft 252 is arranged in the middle of the pair of swing arms 251, and the rotating shaft 252 is fixedly connected to the tail of the swing arm 251. The rotating shaft 252 drives the pair of swing arms 251 to swing in an arc through the first driving assembly 26; the support plate 253 is arranged in the middle of the pair of swing arms 251, and the two ends of the support plate 253 are respectively rotatably connected to the head of the swing arm 251; the bottom of the support plate 253 is provided with a clamping assembly for clamping the lithium battery.

[0038] When the plurality of first material transport channels 211 drive the lithium batteries to the tail of the first material transport channel 211, the swing assembly 25 is controlled by the first driving assembly 26 to move above the tail of the first material transport channel 211, and then the lithium batteries extending out of the first material transport channel 211 are clamped. Then, the first driving assembly 26 drives the swing arm 251 to reverse, thereby moving the support plate 253 holding the lithium batteries above the positioning plate 13 and inserting the lithium batteries into the battery limit column. Then, the clamping assembly at the bottom of the support plate 253 releases the clamping of the lithium batteries, and then the first driving assembly 26 continues to drive the swing arm 251 to rotate, thereby moving the support plate 253 to the top of the first material transport channel 211 again, clamping the next group of lithium batteries, thereby driving the swing arm 251 to swing back and forth by the first driving assembly 26, so that the lithium batteries at the tail end of the first material transport channel 211 can be placed on the positioning plate 13 at a certain interval, and then the lithium batteries are continuously capped and packaged.

[0039] Reference Figure 7As shown: the clamping assembly includes a connecting rod 254, a clamping block 255 and a first cylinder 256; the bottom of the support plate 253 is provided with a notch that is the same number as the battery limit column, and one end of the notch is provided with a semicircular groove corresponding to the diameter of the lithium battery; when the support plate 253 moves to above the positioning plate 13, the axis of the semicircular groove is collinear with the axis of the battery limit column; the connecting rod 254 is slidably arranged inside the support plate 253, and one end of the connecting rod 254 is provided with a vertical plate that passes through the top of the support plate 253; the clamping block 255 is arranged inside the notch and is fixedly connected to the connecting rod 254; the first cylinder 256 is arranged at the top of the support plate 253, and the output shaft of the first cylinder 256 is fixedly connected to the vertical plate of the connecting rod 254.

[0040] When the support plate 253 moves to the top of the first material conveying channel 211, the top of the lithium battery is just accommodated in the semicircular groove at the bottom of the support plate 253. Then the first cylinder 256 at the top of the support plate 253 starts to work and drives the connecting rod 254 to move, thereby driving the clamping blocks 255 in each groove to move until the clamping blocks 255 abut against the outer wall of the lithium battery, and then the lithium battery is clamped and fixed by the cooperation of the clamping blocks 255 and the semicircular groove. After that, the support plate 253 is driven by the swing arm 251 to move above the positioning plate 13, and the support plate 253 is fixed to the top of the positioning plate 13. The lithium battery clamped at the bottom of the support plate 253 is inserted into the battery limiting column above the positioning plate 13, and then the first cylinder 256 drives the connecting rod 254 to move in the opposite direction, thereby driving the clamping block 255 away from the lithium battery, and then placing the lithium battery into the battery limiting column. After that, the swing arm 251 drives the support plate 253 to move to the top of the first material transport channel 211 again to clamp the lithium battery, and the conveyor belt 11 moves the next transport component to the current position, and then repeats the above steps to automatically place the unpackaged lithium battery on the conveyor belt 11 for packaging.

[0041] Reference Figure 6 and Figure 7 As shown, both sides of the support plate 253 are rotatably connected to the swing arm 251 through the first bearing 257 respectively.

[0042] A rotating shaft is provided on both sides of the support plate 253, and a first bearing 257 is sleeved on the rotating shaft, so that the support plate 253 can be rotatably connected to a pair of swing arms 251. At the same time, the rotating shaft is relatively close to the top of the support plate 253, so that when the swing arm 251 drives the support plate 253 to swing in an arc, the support plate 253 always ensures that the bottom is vertically downward.

[0043] Reference Figure 6As shown: the first drive assembly 26 includes a bearing seat 261, a second motor 262, a first bevel gear 263 and a second bevel gear 264; the bearing seat 261 has two and is respectively arranged on the outside of a pair of swing arms 251, the bearing seat 261 is fixedly connected to the front end of the workbench 1, and the bearing seat 261 is rotatably connected to the rotating shaft 252; the second motor 262 is arranged on one side of the workbench 1; the first bevel gear 263 is arranged on the output shaft of the second motor 262; one end of the rotating shaft 252 extends out of the bearing seat 261 and is fixedly connected to the second bevel gear 264, and the second bevel gear 264 and the first bevel gear 263 are meshed with each other.

[0044] The second motor 262 drives the second bevel gear 264 to drive the rotating shaft 252 to rotate through the first bevel gear 263, thereby controlling the swing arm 251 to drive the support plate 253 to move. When the support plate 253 moves above the first material transport channel 211 and clamps and fixes the lithium battery, the second motor 262 reverses to drive the swing arm 251 to drive the support plate 253 to move above the positioning plate 13, and then place the lithium battery into the battery limit column. The second motor 262 periodically rotates forward and reverse, so that the swing arm 251 drives the support plate 253 to swing back and forth.

[0045] Reference Figure 8 As shown: the cap loading assembly 3 includes a second platform 31; the second platform 31 is arranged on one side of the workbench 1, and a second material transport channel 311 for transporting the caps is provided on the second platform 31, and the second material transport channel 311 corresponds one-to-one to the battery limiting columns; the cap loading assembly 3 also includes a displacement assembly 32 for transferring the caps from the second material transport channel 311 to the lithium battery.

[0046] The cap is continuously transported to each second material transport channel 311 by external equipment, and then when the positioning plate 13 containing the lithium battery moves to the bottom of the displacement component 32, the displacement component 32 starts to work, thereby moving the cap transported to the tail of the second material transport channel 311 to the lithium battery, thereby presetting the cap on the lithium battery, and the lithium battery with the pre-set cap continues to move to the bottom of the pressing component 14 driven by the conveyor belt, and then the cap is pressed onto the lithium battery by the pressing component 14, thereby completing the packaging process of the lithium battery.

[0047] Reference Figure 8 、 Figure 9 and Figure 10As shown: the displacement assembly 32 includes a displacement plate 321, an adsorption device 323 and a servo linear guide 324; the displacement plate 321 is arranged above the conveyor belt 11, and mounting plates 322 are provided on both sides of the displacement plate 321; the adsorption devices 323 are arranged at intervals on the displacement plate 321, and the adsorption devices 323 correspond one-to-one to the battery limit columns on the positioning plate 13; the servo linear guides 324 are respectively arranged on the outsides of the two mounting plates 322 and are fixedly connected to the workbench 1, and the slide on the servo linear guide 324 is fixedly connected to the mounting plate 322.

[0048] After that, the displacement plate 321 is moved to the top of the positioning plate 13 by the servo linear guide 324, and the suction cup is facing the lithium battery below, thereby presetting the cap on the lithium battery.

[0049] Reference Figure 9 and Figure 10 As shown, the displacement assembly 32 further includes a second cylinder 325 disposed inside the mounting plate 322 ; the output end of the second cylinder 325 is fixedly connected to the displacement plate 321 ; and the displacement plate 321 and the mounting plate 322 are slidably connected.

[0050] When the servo linear guide 324 drives the displacement plate 321 to move above the second material transport channel 311, the second cylinder 325 pushes the displacement plate 321 downward, thereby driving the suction cup of the adsorption device 323 close to the cap on the second material transport channel 311, so as to adsorb the cap onto the suction cup, and then the second cylinder 325 drives the displacement plate 321 to reset, and then the servo linear guide 324 drives the displacement plate 321 to move above the positioning plate 13, and the second cylinder 325 pushes the displacement plate 321 downward again, so as to preset the cap on the suction cup onto the lithium battery, and then the adsorption device 323 stops adsorbing the cap, and the second cylinder 325 pulls the displacement plate 321 back to its original position, and then moves it to the second material transport channel 311 again through the servo linear guide 324, and then repeats the above steps to continuously preset the cap onto the lithium battery.

[0051] Reference Figure 3As shown: a storage box 16 is provided at the bottom of the workbench 1.

[0052] After the lithium battery is packaged through the press-fitting assembly 14, the conveyor belt 11 continues to drive the transport assembly to move until the transport assembly passes through the arc surface at the tail of the conveyor belt 11 and reaches the bottom of the conveyor belt 11. At this time, the lithium battery on the transport assembly falls into the storage box 16 under the action of gravity, thereby storing the packaged lithium battery.

[0053] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
