Description

Technical Field

[0002] The current weighing of cylindrical lithium-ion batteries basically adopts the straight-line pull-belt type, which is essentially a modified version of the square shell battery. The cylindrical battery with the tray cup is transported to the designated position by the conveyor belt, and then the battery is separated from the tray cup by the attached clamping claw lifting mechanism. The separated battery is transferred to the tooling fixture at the designated weighing position, and then the tooling fixture is lowered to make the battery contact with the weighing tray matched with the weighing sensor alone to carry out the weighing process. After data feedback, the battery tooling fixture rises to re-accept the battery, and then the clamping claw lifter is repeated to grab the battery and mate it with the tray cup separated in the previous section. After pairing, it is transferred from the conveyor belt to the next process.

[0053] Reference Figure 1 , Figure 2 and Figure 3 The turret unit 2 includes a turret support seat 21, a central cam 24 and a turret clamp 23, and the turret clamp 23 is rotatably connected to the turret support seat 21. The turret support seat 21 is the base of the turret unit 2, which is used to carry the components of the turret unit 2; the turret clamp 23 is used to clamp and limit the battery 5 transported by the loading unit 1 to the turret unit 2. The central cam 24 is arranged on the turret support seat 21, and a first cam track 241 is opened on the outer peripheral side of the central cam 24. The turret clamp 23 moves along the first cam track 241 while rotating on the turret support seat 21. The first cam track 241 is opened according to the relative positions of the loading unit 1, the weighing unit 3 and the discharge turntable 4, that is, the turret clamp 23 moves along the first cam track 241 to realize the lifting and lowering of the turret clamp 23, thereby transferring the battery 5 from the loading unit 1 to the weighing unit 3 for weight measurement, and then transferring it to the discharge turntable 4.

[0054] Furthermore, the turret unit 2 also includes a central driving assembly 25, which is used to drive the turret fixture 23 to rotate on the turret support seat 21. The turret support seat 21 includes a support base 211 and a support sleeve 212, the support sleeve 212 is fixedly connected to the top of the support base 211, and the central cam 24 is fixedly sleeved on the support sleeve 212. The central driving assembly 25 includes a first driving motor 251 and a central gear 252, the central gear 252 is rotatably sleeved on the support sleeve 212, the output shaft of the first driving motor 251 is fixedly connected to a driving gear 253, and the driving gear 253 is meshed with the central gear 252, when the first driving motor 251 drives the driving gear 253 to rotate, the central gear 252 is driven to rotate synchronously. The upper end surface of the central gear 252 is fixedly connected with a lower power disk 254, which is rotatably connected to the support sleeve 212. The circumference of the lower power disk 254 is evenly arrayed with fixture support plates 22, and the turret fixture 23 can be raised and lowered on the fixture support plate 22.

[0055] Specifically, the central gear 252 is fixedly connected to the bottom of the lower power disk 254, the support sleeve 212 is sleeved with a central bearing, and the lower power disk 254 is rotatably connected to the support sleeve 212 via the central bearing.

[0056] Furthermore, the central driving assembly 25 also includes an upper driven disk 255 , which is rotatably connected to the supporting sleeve 212 , and one end of the clamp support plate 22 away from the lower power disk 254 is fixedly connected to the upper driven disk 255 .

[0057] Specifically, the end of the support sleeve 212 away from the lower power chuck is rotatably connected to the upper bearing, and the upper driven disk 255 is rotatably connected to the support sleeve 212 through the upper bearing. When the first drive motor 251 drives the lower power disk 254 to rotate, the upper driven disk 255 rotates synchronously with the lower power disk 254.

[0058] Reference Figures 2 to 6 The turret clamp 23 includes a left clamp 231, a right clamp 232, a rotation drive plate 233 and a swivel mounting plate 234. The swivel mounting plate 234 is slidably connected to the clamp support plate 22, and the rotation drive plate 233 is rotatably connected to the swivel mounting plate 234. The left clamp 231 and the right clamp 232 are rotatably connected to the rotation drive plate 233, and the left clamp 231 and the right clamp 232 slide on the swivel mounting plate 234 along the horizontal direction, that is, when the rotation drive plate 233 rotates on the swivel mounting plate 234, the left clamp 231 and the right clamp 232 are driven to slide on the swivel mounting plate 234 in a direction away from or close to each other, so as to realize the opening and closing of the left clamp 231 and the right clamp 232.

[0059] A bottom support plate 223 is fixedly arranged at the bottom of the clamp support plate 22, and a limiting groove 2231 is opened on the bottom support plate 223. The shape and size of the limiting groove 2231 match the shape and size of the battery 5 support cup. When the loading unit 1 transfers the battery 5 with the support cup to the turret unit 2, the support cup is inserted into the limiting groove 2231 to limit and fix the support cup so that the battery 5 with the support cup can circulate in the turret unit 2.

[0060] Furthermore, a guide rail 221 extending in a vertical direction is fixedly connected to the clamp support plate 22, a first slider 2341 is fixedly connected to the swivel mounting plate 234, the first slider 2341 is slidably connected to the guide rail 221, a connecting mounting block 2344 is fixedly connected to the side of the swivel mounting plate 234 facing the guide rail 221, a first pulley 2343 is fixedly connected to the side of the connecting mounting block 2344 facing away from the swivel mounting plate 234, and the first pulley 2343 slides on the first cam track 241.

[0061] Reference Figures 3 to 9 When the central driving assembly 25 drives the lower power disk 254 and the upper driven disk 255 to rotate and then drives the fixture support plate 22 to rotate, the turret fixture 23 arranged on the fixture support plate 22 is driven to rotate around the central axis 257 of the lower power disk 254. Since the central cam 24 is fixedly arranged, the first pulley 2343 on the turret fixture 23 will move along the first cam track 241 during the rotation process, thereby realizing the lifting and lowering movement of the turret fixture 23 on the corresponding fixture support plate 22. The first cam track 241 guides the sliding of the turret fixture 23 on the fixture support plate 22, that is, when the turret fixture 23 needs to rise, the corresponding first cam track 241 presents an upward trend track setting in this section; when the turret fixture 23 needs to fall, the corresponding first cam track 241 presents a downward trend track setting in this section; when the turret fixture 23 needs to maintain the same horizontal height, the corresponding first cam track 241 presents a horizontal trend track setting in this section.

[0062] Reference Figure 5 and Figure 6 Furthermore, a pressing driving arm 222 is slidably connected to the clamp support plate 22 for driving the rotating driving plate 233 to rotate, and the pressing driving arm 222 is fixedly connected to a pressing slider 2221, which is sleeved on the clamp support plate 22, and the pressing slider 2221 is slidably connected to the guide rail 221, and the pressing driving arm 222 is located above the turret clamp 23. When the pressing driving arm 222 slides downward and continuously presses the rotating driving plate 233, the rotating driving plate 233 rotates under the pressing action of the pressing driving arm 222, driving the left clamp 231 and the right clamp 232 to move away from each other, that is, at this time, the left clamp 231 and the right clamp 232 are in an open state.

[0063] Furthermore, a second cam track 242 is correspondingly provided on the central cam 24, and a second pulley 2222 is fixedly connected to the side of the downward pressing slider 2221 facing away from the downward pressing driving arm 222, and the second pulley 2222 slides on the second cam track 242, and the second cam track 242 guides the lifting and lowering movement of the downward pressing driving arm 222, and the first cam track 241 and the second cam track 242 are matched and arranged. Specifically, the lifting and lowering trends of the first cam track 241 and the second cam track 242 are synchronously arranged, and by changing the first cam track 241 and the second cam track 242 The distance between the cam tracks 242 enables the downward pressure driving arm 222 and the turret clamp 23 to approach and move away from each other, thereby realizing the opening and closing of the turret clamp 23. That is, when the first cam track 241 and the second cam track 242 are close to each other, the downward pressure driving arm 222 and the turret clamp 23 are also close to each other. At this time, as the turret unit 2 rotates, the downward pressure driving arm 222 drives the turret clamp 23 to open; when the first cam track 241 and the second cam track 242 are far apart, the downward pressure driving arm 222 is relatively far away from the turret clamp 23, and the turret clamp 23 is in a clamped state.

[0064] Furthermore, a waist-shaped slide groove 2331 is provided on the rotation driving plate 233, and the left clamping jaw 231 and the right clamping jaw 232 are both slidably arranged in the waist-shaped slide groove 2331. A clamping jaw slide rail 2342 extending in the horizontal direction is fixedly connected to the rotary mounting plate 234. A clamping jaw slider 2311 is fixedly connected to the left clamping jaw 231 and the right clamping jaw 232, and the two clamping jaw sliders 2311 are slidably connected to the clamping jaw slide rail 2342. When the rotation driving plate 233 rotates under the downward pressure of the downward pressure driving arm 222, the rotation action of the rotation driving plate 233 is converted into the horizontal sliding of the left clamping jaw 231 and the right clamping jaw 232 under the cooperation of the waist-shaped slide groove 2331 and the clamping jaw slide rail 2342, so that the opening action of the left clamping jaw 231 and the right clamping jaw 232 is realized.

[0065] Furthermore, the turret clamp 23 also includes a tension spring (not shown in the figure), one end of the tension spring is fixedly connected to the left clamp 231, and the other end is fixedly connected to the right clamp 232. When the left clamp 231 and the right clamp 232 are in an opening action, the tension spring elastically stretches. When the rotation drive plate 233 is free from the pressing action of the downward pressing drive arm 222, the tension spring elastically contracts, and the left clamp 231 and the right clamp 232 slide towards each other under the tension of the tension spring, that is, the left clamp 231 and the right clamp 232 are in a closing action, and at this time, the rotation drive plate 233 also rotates to reset.

[0066] Specifically, the process of clamping the battery 5 is as follows: the loading unit 1 conveys the battery 5 with the tray to the turret unit 2, the battery 5 with the tray is stuck in the bottom tray 223, and the battery 5 with the tray flows from the loading unit 1 to the turret unit 2. At this time, the pressing drive arm 222 slides along the second cam track 242 to a pressing state, that is, the pressing drive arm 222 presses against the rotating drive plate 233, so that the rotating drive plate 233 rotates clockwise until the left jaw 231 and the right jaw 232 are in an open state. At this time, the battery 5 with the tray is located between the left jaw 231 and the right jaw 232; the central drive assembly 25 drives the clamp support plate 22 to continue to rotate counterclockwise, and the pressing drive arm 222 rises along the second cam track 242. At this time, the rotating drive plate 233 is separated from the pressing action of the pressing drive arm 222, and the tension spring elastically contracts, pulling the left jaw 231 and the right jaw 232 to close, thereby clamping the cylindrical battery 5. Then, the central drive assembly 25 drives the turret unit 2 to rotate continuously counterclockwise. At this time, the downward drive arm 222 and the turret clamp 23 rise synchronously, and the turret clamp 23 clamps the battery 5. During the rising process, the turret clamp 23 drives the battery 5 to separate from the tray cup. At this time, the tray cup is still stuck in the bottom tray 223 and rotates synchronously with the turret unit 2.

[0067] Reference Figures 2 to 8 The weighing unit 3 includes a weighing support platform 31, a weighing sensor 32, a weighing support plate 33 and a weighing lower pressure plate 35.

A plurality of weighing sensors 32 are arranged on the weighing support platform 31 to form a plurality of weighing stations, which can weigh a plurality of batteries 5 at the same time. The weighing support platform 31 is provided with a weighing side plate 34 located on both sides of the weighing sensor 32. The weighing support plate 33 can be raised and lowered on the weighing side plate 34. The weighing support plate 33 is used to carry the cylindrical battery 5. The weighing support plate 33 is provided with an avoidance hole 331. The induction part of the weighing sensor 32 passes through the avoidance hole 331 to support the cylindrical battery 5, thereby weighing the cylindrical battery 5. The weighing pressing plate 35 is connected to the central driving assembly 25, and the central driving assembly 25 drives the weighing pressing plate 35 to rise and fall, and the weighing pressing plate 35 is used to drive the weighing supporting plate 33 to rise and fall. When the central driving assembly 25 drives the weighing pressing plate 35 to fall, it drives the weighing supporting plate 33 to fall, and the weighing supporting plate 33 drives the cylindrical battery 5 to fall during the falling process. When the cylindrical battery 5 contacts the sensing part of the weighing sensor 32, the weighing sensor 32 performs a weighing test on the cylindrical battery 5; after the weighing test is completed, the weighing supporting plate 33 rises, driving the cylindrical battery 5 to rise to separate from the weighing sensor 32.

[0068] Furthermore, the weighing lower pressure plate 35 can be raised and lowered on the weighing side plate 34. The weighing side plates 34 located on both sides of the weighing sensor 32 are fixedly connected to the opposite side with a downward pressure slide rail 341 extending in the vertical direction, and the weighing support plate 33 is fixedly connected to the opposite sides with a support plate slider, and the support plate slider is slidably connected to the downward pressure slide rail 341 on both sides. The weighing lower pressure plate 35 is fixedly connected to the opposite sides with a pressure plate slider, and the pressure plate slider is slidably connected to the downward pressure slide rail 341, and the weighing lower pressure plate 35 is located above the weighing support plate 33. When the weighing lower pressure plate 35 slides downward, it will drive the weighing support plate 33 to descend together.

[0069] Furthermore, the central drive assembly 25 also includes a second drive motor 256 and a central shaft 257. The second drive motor 256 is fixedly connected to the turret support seat 21, and the output shaft of the second drive motor 256 is fixedly connected to the central shaft 257. The central shaft 257 is arranged in the support sleeve 212 and is rotatably connected to the support sleeve 212. The top end of the central shaft 257 protrudes out of the support sleeve 212, and the top end of the central shaft 257 is fixedly connected to the top cam 26, that is, the top cam 26 covers the top cam 26. Located above the turret unit 2, the top cam 26 is preset with a full circle of convex edges 261 of a high section, a slope section and a low section. A third pulley 352 is fixedly connected to the weighing lower pressure plate 35, and the third pulley 352 rolls on the convex edge 261. When the third pulley 352 descends from the slope section of the top cam 26 to the low section, the weighing lower pressure plate 35 slides downward on the lower pressure slide rail 341, and the lower pressure arm 351 also descends with the weighing lower pressure plate 35. The descent of the weighing lower pressure plate 35 drives the weighing support plate 33 to descend.

[0070] Specifically, the process of the battery 5 falling into the weighing unit 3 is as follows: when the turret fixture 23 drives the battery 5 to flow to the top of the weighing unit 3, the second drive motor 256 is started, and the drive motor drives the central shaft 257 to rotate and then drives the top cam 26 to rotate, and the top cam 26 rotates from the high section to the low section. In this process, the third pulley 352 rolls with the convex edge 261 of the top cam 26, driving the weighing lower pressure plate 35 to move downward, and the lower pressure arm 351 presses against the rotating drive plate 233 and continues to rotate. When sliding downward, the rotating drive plate 233 is driven to rotate. At this time, the left jaw 231 and the right jaw 232 slide in the direction away from each other, that is, the left jaw 231 and the right jaw 232 are in an open state, releasing the battery 5, and the battery 5 falls onto the weighing support plate 33 located below the turret clamp 23; the weighing lower pressure plate 35 continues to descend until the third pulley 352 rolls to the low section of the convex edge 261. At this time, the battery 5 stands alone on the weighing sensor 32, and the battery 5 can be weighed and measured.

[0071] Furthermore, a weighing limit plate 36 is also provided on the weighing lower pressing plate 35. The weighing limit plate 36 is fixedly connected to the side of the weighing lower pressing plate 35 close to the weighing support plate 33. A limit through hole 361 is provided on the weighing limit plate 36, and the diameter of the limit through hole 361 is slightly larger than the diameter of the battery 5. When the weighing lower pressing plate 35 presses down the battery 5 to stand alone on the weighing support plate 33, the battery 5 is located in the limit through hole 361, that is, the weighing limit plate 36 virtually surrounds the battery 5, but does not contact the battery 5. The weighing limit plate 36 limits the battery 5 on the weighing support plate 33, effectively preventing the possibility of the battery 5 tipping over during the weighing detection process.

[0072] Reference Figure 7 and Figure 8 Furthermore, the weighing unit 3 further includes a first return spring 37 and a second return spring 38. The first return spring 37 is used to drive the weighing lower pressure plate 35 to reset when the convex edge 261 of the top cam 26 above the third pulley 352 is in the high position section; the second return spring 38 is used to drive the weighing support plate 33 to reset. Specifically, a cross plate is fixedly connected to the top of the weighing side plate 34, one end of the return spring is fixedly connected to the cross plate, and the other end is fixedly connected to the weighing lower pressure plate 35. A connecting plate 342 located below the weighing support plate 33 is fixedly connected between the two weighing side plates 34, and a guide column 343 is fixedly connected to the connecting plate 342. One end of the second return spring 38 is fixedly connected to the connecting plate 342, and the other end is fixedly connected to the weighing support plate 33. The weighing support plate 33 is provided with a clearance hole for the guide column 343 to pass through. When the weighing pressing plate 35 descends, the elasticity of the first return spring 37 stretches and the elasticity of the second return spring 38 compresses; when the convex edge 261 of the top cam 26 above the third pulley 352 rotates to the high position, the weighing pressing plate 35 is separated from the downward pressure limit of the top cam 26, the elasticity of the first return spring 37 contracts, driving the weighing pressing plate 35 and the weighing limit plate 36 to reset, and the elastic release of the second return spring 38 drives the weighing support plate 33 to reset. Since the pressing arm 351 rises with the weighing pressing plate 35, the rotating driving plate 233 is separated from the pressing action of the pressing arm 351, and the left clamping jaw 231 and the right clamping jaw 232 slide towards each other under the action of the tension spring to clamp the battery 5.

[0073] Reference Figure 2 and Fig.10The feeding unit 1 is used to receive the cylindrical battery 5 on the production line and input the cylindrical battery 5 into the turret unit 2. Specifically, the feeding unit 1 includes a feeding screw 14, a feeding turntable 13 and a feeding drive assembly 12. The feeding unit 1 also includes a feeding base 11, which is the base of the feeding unit 1 and is used to carry and install various components. The feeding screw 14 is arranged on one side of the feeding turntable 13 to input the battery 5 into the feeding turntable 13. The feeding turntable 13 is rotatably arranged on the feeding base 11. The feeding turntable 13 is axially evenly spaced with a plurality of feeding grooves 1311, and the arc length between two adjacent feeding grooves 1311 on the feeding turntable 13 is equal to the pitch of the feeding screw 14, so that the feeding screw 14 and the feeding turntable 13 are perfectly meshed and fed. The rotation of the feeding screw 14 drives the battery 5 to move horizontally to the feeding turntable 13 and is inserted into the feeding slot 1311 of the rotating feeding turntable 13. The feeding turntable 13 rotates to transfer the battery 5 with the cup in the feeding slot 1311 to the turret unit 2. The installation and driving structure of the feeding screw 14 can refer to the prior art and will not be elaborated in detail here. The feeding unit 1 also includes structures such as a read-write head. The installation structure and working principle of the read-write head refer to the prior art and will not be elaborated here.

[0074] The loading drive assembly 12 is used to drive the loading turntable 13 to operate. Specifically, the loading drive assembly 12 includes a third driving motor 121, a driving shaft 122 and a driving ratchet 123. The third driving motor 121 is fixedly arranged on the loading base 11, and the output shaft of the third driving motor 121 is fixedly connected to the driving shaft 122. The driving ratchet 123 is fixedly sleeved on the driving shaft 122. A pawl 124 is connected to the loading turntable 13. Specifically, the pawl 124 is rotatably connected to the side of the loading turntable 13 facing the driving ratchet 123, and the ratchet cooperates with the pawl 124.

[0075] Furthermore, the loading turntable 13 includes a loading tooth piece 131 and a rocker arm 132 , one end of the rocker arm 132 is sleeved on the driving shaft 122 and rotatably connected to the driving ratchet 123 , and the other end of the rocker arm 132 is fixedly connected to the loading tooth piece 131 .

[0076] Furthermore, the feeding tooth piece 131 is in a fan-shaped structure, and the feeding turntable 13 is provided with three feeding tooth pieces 131 and three swing rods 132, and the swing rods 132 are arranged one by one in correspondence with the feeding tooth pieces 131. The three swing rods 132 are stacked and arranged on the driving shaft 122, and correspondingly, three driving ratchets 123 are also arranged on the driving shaft 122, and the driving ratchets 123 and the swing rods 132 are also arranged one by one in correspondence, and a bearing is arranged between the swing rods 132 and the corresponding driving ratchets 123 to realize the rotational connection between the swing rods 132 and the ratchets. The three feeding tooth pieces 131 are assembled into a 270° fan-shaped structure, that is, there is a 90° gap on the feeding turntable 13. In order to ensure that the upper end surfaces of the three feeding tooth pieces 131 are located in the same horizontal plane, a padding block 133 is also arranged between the two swing rods 132 located below and the feeding tooth pieces 131.

[0077] The implementation process of the feeding unit 1 is as follows: the feeding screw 14 rotates to transfer the battery 5 with the support cup to the feeding turntable 13, and the third driving motor 121 drives the driving ratchet 123 to rotate. Under normal circumstances, the pawl 124 is stuck in the driving ratchet 123. When the power of the third driving motor 121 is transmitted to the driving ratchet 123, since the driving ratchet 123 is stuck with the pawl 124, the driving ratchet 123 rotates to drive the feeding turntable 13 to rotate clockwise. When the feeding turntable 13 rotates to the meshing point with the bottom support plate 223 on the clamp support plate 22, there is a rotation speed difference between the turret unit 2 and the feeding turntable 13, that is, the speed of the turret unit 2 is greater than the rotation speed of the feeding turntable 13. Since there are batteries 5 with the support cup on the feeding tooth plate 131 during the rotation process, The loading tooth piece 131 is partially inserted into the corresponding limiting groove 2231 of the bottom support plate 223. At this time, the loading tooth piece 131 will accelerate the rotation with the turret unit 2 (at this time, the driving ratchet 123 and the pawl 124 are in a loose state), and the loading tooth piece 131 can rotate freely with the turret unit 2. When all the batteries 5 on the loading tooth piece 131 enter the turret unit 2, the turret unit 2 no longer drives the loading tooth piece 131 to rotate synchronously, and the speed difference between the loading tooth piece 131 and the corresponding driving ratchet 123 disappears. The pawl 124 is again inserted into the teeth of the driving ratchet 123 to restore the original rotation speed. At this time, because there is a 90° gap in the loading turntable 13, the weighing unit 3 weighs the battery 5 during the time when the next loading tooth piece 131 rotates at a uniform speed to the meshing point. Three feeding teeth 131 are arranged so that there are some gaps in the feeding turntable 13. The weighing unit 3 can use the gaps to perform weighing. By using this time difference, each unit can perform weighing continuously without stopping the machine, thereby effectively improving the detection efficiency.

[0078] Reference Figure 1 and Figure 2The discharge turntable 4 includes a discharge turntable 41 and a driving gear 42. The discharge turntable 4 is provided with edge notches 411 in a uniform array. The driving gear 42 is fixedly connected to the bottom of the discharge turntable 41, and the driving gear 42 is meshed with the center gear 252. The first driving motor 251 drives the center gear 252 to rotate, thereby driving the driving gear 42 to rotate, so as to achieve the purpose of the discharge turntable 41 transferring the batteries 5 from the turret unit 2 to the discharge turntable 4.

[0079] The overall implementation process of the present invention is:

[0080] The feeding screw 14 uniformly conveys the battery 5 with the tray cup to the upper feeding turntable 13, and the third drive motor 121 drives the feeding turntable 13 to rotate, and conveys the battery 5 with the tray cup to the turret unit 2. In this process, the feeding unit 1 completes the feeding action of the tray cup battery 5, and completes the code reading action through the read-write head set at the bottom of this position; the first drive motor 251 drives the lower power disk 254 and the upper follower disk to rotate, thereby driving the rotation of the turret fixture 23 and the downward pressure drive arm 222. During the rotation process, the third drive motor 121 on the downward pressure drive arm 222 The second pulley 2222 rolls on the second cam track 242 to press the downward drive arm 222 downward, driving the rotating drive plate 233 to rotate, and the turret clamp 23 is in an open state at this time; when the turret clamp 23 rotates to the meshing point of the loading turntable 13, the downward drive arm 222 rises along the second cam track 242, and the rotating drive plate 233 is separated from the pressing effect of the downward drive arm 222, and the left clamp 231 and the right clamp 232 are closed to clamp the battery 5; the first drive motor 251 drives the turret unit 2 to continue to rotate counterclockwise, During this process, the turret clamp 23 and the downward pressure driving arm 222 rise synchronously along the first cam track 241 and the second cam track 242 respectively; when the turret clamp 23 rotates to the top of the weighing unit 3 and the weighing plates 33 on the weighing unit 3 are full of batteries 5, the first driving motor 251 stops intermittently, and the turret clamp 23 stops rotating at this time. At the same time, the second driving motor 256 is started, and the weighing downward pressure plate 35 drives the turret clamp 23 to release the battery 5, and drives the weighing plate 33 and the weighing limit plate 36 to descend. , so that the battery 5 falls onto the weighing sensor 32, and then the second drive motor 256 is also stopped intermittently, and weighing detection is performed at this time; after the weighing is completed, the second drive motor 256 is driven to rotate intermittently, so that the weighing support plate 33 drives the battery 5 to rise to the turret clamp 23. During the rising process, the turret clamp 23 clamps the battery 5. At this time, the first drive motor 251 is rotated to drive the turret clamp 23 to rotate, and drive the battery 5 to flow to the discharge turntable 4. The turret clamp 23 is released, and the discharge turntable 4 rotates the battery 5 out.

In the second embodiment, the central driving assembly 25 includes a dual-axis motor 258, a central gear 252, a first cam divider 2581 and a second cam divider 2582. The first cam divider 2581 and the second cam divider 2582 are respectively connected to the two output shafts of the dual-axis motor 258. The output end of the first cam divider 2581 is connected to an adapter, which is connected to the driving gear 253. The output end of the second cam divider 2582 is connected to the central shaft 257. The dual-axis motor 258 drives the first cam divider 2581 to work, which can drive the driving gear 253 to rotate, and then drive the central gear 252 to rotate to realize the rotation of the turret unit 2. The dual-axis motor 258 drives the second cam divider 2582 to work, which drives the central shaft 257 to rotate, and then drives the top cam 26 to rotate to realize the lifting and lowering of the weighing lower pressing plate 35. A dual-axis motor 258 is provided, and in conjunction with the use of a divider, only one driving source is needed to drive the driving gear 253 and the center shaft 257 respectively, thereby achieving mutual coordination of transportation and weighing. There is no need to adjust the coordination relationship between the two driving devices, and the operation steps and equipment structure are effectively simplified.
